Description

[0001] The invention relates to a door fastening device and a cover element for a device for actuating a lock.

[0002] Devices for operating a lock, in particular a locking cylinder actuating element such as a key or a locking cylinder pin, are known from the prior art. Such devices are also referred to as intelligent locks or smartlocks and enable actuator-assisted opening and closing of the bolt of a door lock. For this purpose, the smartlock can move a bolt of the door lock from the closed position to an open position or vice versa, without the user having to manually operate a key. As a rule, such a smartlock only allows authorized persons to operate the door lock, e.g. those carrying a transponder or smartphone that is authorized to control the smartlock. Controlling the smartlock via a keypad or fingerprint sensor is also possible.

[0003] A smart lock usually includes an electric motor that generates drive energy for the closing or opening movement. A smart lock also includes energy sources such as non-rechargeable primary batteries or rechargeable secondary batteries (accumulators) that provide the electrical power to operate the electric motor. These batteries can also supply power to a control device and other elements of the smart lock. A control device of the smart lock can, for example, receive a control signal to open or close the door lock and then control the electric motor to carry out the corresponding movement. However, it is also conceivable for the control device to control the electric motor independently without receiving a control signal, e.g. in the case of a time control.

[0004] Currently, there are a variety of different locking cylinders, including EU profile cylinders, dead-bolt locks, and oval cylinders. Furthermore, the arrangement of the door handle and lock also varies on current doors. For example, the handle can be located above or below the lock.

[0005] Different smart lock solutions exist for the various locking cylinder variants and arrangements. A fundamental distinction must be made between solutions that require changing the locking cylinder and solutions that are based on the existing lock and do not require changing the locking cylinder. To enable simple, especially retrofitting, installation of a smart lock, it is desirable not to have to change the locking cylinder. Easy installation of the smart lock on a variety of locking cylinders or locks, as well as for a variety of relative arrangements between the door handle and the door lock, is particularly desirable. Furthermore, the best possible protection of the components of a smart lock is desirable, especially against external influences such as dirt particles and moisture.

[0006] Furthermore, it may be desirable to provide a smart lock with low weight, low installation space, and low energy consumption, while simultaneously reducing the locking time. Furthermore, reliable operation should be possible over a wide range of rotation angles. The noise level during operation should also be low. The smart lock should also be suitable for operating a variety of locking cylinders and locks, as well as for a variety of relative arrangements between the door handle and the door lock.

[0007] US Pat. No. 9,546,504 B2 discloses a motorized lock for a door, such as an apartment door. The document also discloses an adapter plate for mounting the lock on a door.

[0008] DE 10 2019 107 282 A1 discloses a door lock actuating device for actuating a door lock. The document discloses a support for mechanical connection to the door.

[0009] The disclosed door lock actuation devices are also characterized by the fact that both the batteries and a stator of the drive device used are arranged on or in a carrier body, which, when mounted on the door, is fixed relative to the door. However, this increases, among other things, the space required for the carrier body and thus for the smart lock.

[0010] The technical problem therefore arises of creating a door fastening device for a device for actuating a lock that enables simple mounting of the smart lock on a variety of locking cylinders or locks, as well as for a variety of relative arrangements between the door handle and the door lock. Furthermore, the technical problem arises of creating a cover element for a device for actuating a lock that provides the best possible protection for the components of the device, particularly against external influences such as dirt particles and moisture.

[0011] These components should also be designed in such a way that the device can be designed with very little installation space, wherein the device can in particular have at least one of the advantageous properties mentioned above and is particularly suitable for actuating a large number of locking cylinders or locks and for mounting on doors with a large number of relative arrangements between the door handle and the door lock.

[0012] The solution to the technical problem is achieved by the subject matter having the features of the independent claims. Further advantageous embodiments of the invention are set forth in the subclaims.

[0013] A door fastening device for a device for actuating a lock is proposed. The door fastening device, which can also be referred to as a door fastening element, refers to an element that can be fastened to the door, in particular in the region of a locking cylinder. The door fastening device can then be fastened to the door in a fixed position relative to the door. The actuating device, in particular a carrier body of this device, can then in turn be fastened to the door fastening device, in particular likewise in a fixed position. The door fastening device can in particular be designed as a door fastening plate, preferably as a circular plate. The door fastening device can have at least one recess or through-opening for arranging a locking cylinder section.The door fastening device can be plugged onto such a section, with the protruding section then extending into the recess. A locking cylinder actuating element arranged in the receiving section of the rotating body can then extend from the rotating body into the locking cylinder through this through-opening.

[0014] The central through-opening can have a plurality of sections, in particular a plurality of circular sections with mutually different diameters. The sections can be connected via a connecting section. While a center line of a first section can correspond to the longitudinal axis of the device (when this is fastened to the door fastening device), a center line of the further section can be arranged radially offset from the longitudinal axis of the device. The further section can then serve to accommodate a screw or other fastening means, which can be screwed from the side of the door fastening device facing away from the door through the further section into any threaded holes present in the locking cylinder or lock or the door.

[0015] The device can, in particular, generate a locking movement of the lock, which serves to open (unlock) the lock or close (lock) the lock. The device can, in particular, generate a movement of at least one movable locking element of the lock. Such a locking element can be, for example, a latch, a bolt, or a pin, which is moved into a recess in a strike plate or frame for locking.

[0016] This device can comprise a carrier body. The carrier body is designed for direct or indirect mechanical fastening to the door. With direct fastening, the carrier body can be fastened directly to the door or a door element. With indirect fastening, the carrier body can be fastened to the door or a door element via at least one intermediate element, e.g. the door fastening device. The carrier body can be fastened directly or indirectly, e.g. on or in a door leaf, on or in a fitting element of the door or on or in a mortise lock, which can be arranged in the door. In other words, the device, in particular the carrier body, can be fastened to the door or a door element or integrated into it. When mounted on the door, which is referred to below as the mounted state, the carrier body is arranged stationary relative to the door.

[0017] The door fastening device can thus be used for attachment to a door element. The attachment to the door can then be made via the door element.

[0018] The door element can, in particular, refer to an element that is fixedly arranged or attached to the door leaf. Such a door element can, in particular, be a locking cylinder of a door lock or another element of the door lock, e.g., a handle or knob for operating the lock, a fitting, in particular a security fitting, but also a different element of the door lock.

[0019] The carrier body can have at least one connecting element for fastening to the door or to the door fastening device. For the purposes of this invention, unless expressly stated otherwise, the term "have" can also have the meaning of the terms "form" or "comprising". A connecting element for the purposes of this invention can serve to create a mechanical connection between two components to be connected. A (mechanical) connection for the purposes of this invention can be a detachable or a non-detachable connection. Examples of a detachable connection are, for example, a snap-in connection, a clamp connection or a screw connection. Examples of a non-detachable connection are, for example, an adhesive connection or a welded connection. The detachable or non-detachable connection can be a positive-locking, a force-locking and / or a material-to-material connection.The components to be connected can have corresponding connecting elements that interact with each other to create the mechanical connection. An example of corresponding connecting elements is a thread and a screw.

[0020] A body or element within the meaning of this invention can comprise several different partial bodies or partial elements that can be mechanically connected to one another. However, it is also possible for a body to be formed as a single piece. This can mean that the body / element consists of a single piece of material or a single part and not of several different parts. Thus, a single-piece body can be formed as a monolithic, i.e., coherent body that cannot be separated without destruction.

[0021] The device can have a first end facing the door and a further end facing away from the door. When mounted on the door, the first end faces the door and is in particular fastened thereto, wherein the further end is a free end facing away from the door. The term "facing the door" in the sense of this invention can refer to the mounted state and can also mean facing the first end of the device. The term "facing away from the door" in the sense of this invention can likewise refer to the mounted state and can also mean facing the further end of the device. Accordingly, the door fastening device can have a side facing the door and a side facing away from the door.

[0022] The entire device can be cylindrical. Thus, a side wall of the device can form a circumferential surface of a cylinder. A front section of the device at the further end can form a cover section of the cylinder. A front section of the device at the first end can form a base section of the cylinder. Components of the device explained in more detail below, in particular the drive device and the control device, can then be arranged in an internal volume enclosed by the outer wall of the device.

[0023] The carrier body can also have a first end facing the door and a further end facing away from the door. In the assembled state, the first end faces the door, with the further end being an end facing away from the door. The carrier body is preferably designed as a rotationally symmetrical body. A (central) longitudinal axis (center axis), which can be an axis of symmetry of the carrier body, can correspond to a central longitudinal axis of the device, wherein this central longitudinal axis of the device can be oriented from the end facing the door to the end facing away from the door. The central longitudinal axis of the device can correspond to an axis of symmetry of the device, but this is not mandatory. The longitudinal axis can simultaneously correspond to an axis of rotation of a rotating body of the device. However, embodiments of the device are also conceivable in which the longitudinal axis does not correspond to this axis of rotation. In such cases, this can, for example,be arranged parallel to the axis of rotation but at a distance from it.

[0024] The support body can have at least one section for attaching elements of the device, which, when mounted, are then also arranged stationary relative to the door. In particular, at least one of the following elements can be attached to the support body: - a control device for controlling the operation of the device, - a printed circuit board on which the control device and / or at least one light source and / or at least one communication device and / or further electrical and / or electronic components can be arranged, - a stator of a drive device, - means for energy transmission such as conductor elements for electrically connecting different elements of the device, - a cover element - a part of a gearbox explained below.

[0025] However, this list is not exhaustive. The support body can further comprise at least one section for supporting elements of the device, which, in the assembled state, are arranged so as to be movable, in particular rotatable, relative to the door. Such an element can, in particular, be a rotating body of the device, which can thus be rotatably mounted on the support body.

[0026] It is possible for the carrier body to have at least two sections with different outer diameters. For example, the carrier body can comprise a first section, in particular a hollow section, with a first outer diameter and a further section with a further outer diameter, wherein the further outer diameter is smaller than the first outer diameter. The carrier body can also comprise a base section for connecting these two sections with different outer diameters. This base section can in particular be arranged in the inner volume of the first section and thus form an intermediate wall in this inner volume, which divides the inner volume into several, in particular two, sub-volumes. The further section can then be arranged in a sub-volume facing away from the door. The further section can be fastened to the base section and have a fastening section for fastening the stator.The further section can also have at least one bearing section for rotatably supporting the rotating body. The first section can have a receiving section for receiving a part of the rotating body, which can be arranged in particular in a partial volume of the described interior volume facing the door.

[0027] The carrier body can also have means for energy transmission and / or position determination. Via such means, for example, energy can be transmitted from a battery, i.e. a primary or secondary battery, to the drive device and / or to a control device. Such means can also be transmitted from an electrical connection element of the device to a battery. These means can be made of electrically conductive material. For example, the means can be designed as a conductor track or comprise such a track. Furthermore, such means can comprise pins made of conductive material. These can be attached to the carrier body in an exposed manner or at least partially integrated into the material of the carrier body. Such means can also be designed as conductive cables. Means for position determination enable, for example, a position signal to be transmitted to a control device.

[0028] It is possible for the carrier body to comprise a fastening body for fastening the carrier body, which can also be referred to as a carrier fastening body or carrier fastening element, to the door fastening device. The carrier body can be mechanically connected to this fastening body, e.g. via at least one fastening element designed as a locking element. For example, the fastening body can have locking recesses for receiving locking elements of the carrier body. Of course, the fastening body can alternatively or cumulatively also have locking elements for arrangement in locking recesses of the carrier body. However, it is also possible for the carrier body and the carrier fastening body to be formed in one piece. The fastening body can then have fastening and / or guide elements, explained in more detail below, for fastening to the door fastening device.The fastening body can be designed as a hollow cylinder and can be arranged in particular at an end of the carrier body facing the door.

[0029] Furthermore, the device can comprise a rotating body for generating the locking movement of the lock, which is rotatably mounted in or on the carrier body.

[0030] To generate the locking movement, the rotating body can have an interface for direct or indirect mechanical coupling with at least one locking element of the lock. This can mean that a rotational movement of the rotating body, which is transmitted via the interface to the lock or an element of the lock, can cause a locking movement of the locking element.

[0031] For example, the rotating body can have at least one section for receiving the lock cylinder actuating element. A lock cylinder actuating element can, in particular, be a key or a lock cylinder pin. Such a lock cylinder pin can have various geometric designs.

[0032] By actuating, in particular rotating, the locking cylinder actuating element, a bolt of the door lock can be moved from the closed position to an open position or vice versa if the locking cylinder actuating element can interact with the locking cylinder of the lock (e.g. the key is inserted into the locking cylinder). The locking cylinder actuating element can be arranged in a fixed position relative to the rotating body in or on the latter. The receiving section enables a rotationally fixed, in particular a positive and / or non-positive, connection of at least one section of the locking cylinder actuating element and the rotating body. The receiving section can be designed, for example, as a recess, in particular a blind hole-like recess, in a section of the rotating body.

[0033] However, it is also conceivable for the rotating body to have an interface for receiving an actuating element that serves to actuate a different element of the lock than the locking cylinder. The rotating body can also have an interface for directly actuating such a different element. In this case, for example, a rotary movement of the rotating body can be transmitted to the locking element not via the locking cylinder but via a different element.

[0034] The rotating body can also have a first end facing the door and a second end facing away from the door. In the assembled state, the first end faces the door, while the second end is an end facing away from the door. The rotating body is also preferably designed as a rotationally symmetrical body. A (central) longitudinal axis of the rotating body, which can be an axis of symmetry of the rotating body, can correspond to the longitudinal axis of the support body and / or the device, but can also be offset therefrom.

[0035] The device can comprise at least one bearing device for supporting the rotating body, wherein the rotating body is rotatably mounted in or on the carrier body via this bearing device. Such a bearing device can be designed as a rolling bearing, in particular as a ball bearing. However, it is also conceivable to design the bearing device as a plain bearing, fluid bearing, magnetic bearing, or with a different mode of operation. The bearing device can also implement a combination of different bearing principles, for example, a combination of ball and plain bearings.

[0036] The rotating body can have a manual actuation section. This will be explained in more detail below. The rotating body can have at least two sections or partial bodies with different outer diameters, which will also be explained in more detail below.

[0037] The device can further comprise a drive device for driving the rotating body. The drive device can comprise a stator and a rotor. The stator can denote a stationary part of the drive device that does not move during operation of the drive device to move the rotor. The rotor can therefore denote a movable, in particular rotatable, part of the drive device. The drive device, in particular the rotor, can be or become mechanically coupled to the rotating body to drive it. The drive device can be designed as a synchronous motor, in particular as a permanent magnet synchronous motor, as an asynchronous motor, as a servomotor, as a stepper motor, as a DC motor, in particular a brushless DC motor, or with a different mode of operation.

[0038] The device may comprise at least one bearing device for supporting the rotor, wherein the rotor is rotatably mounted in or on the support or rotating body, in particular on the stator, via this bearing device. Regarding the design of this bearing device, reference can be made to the previous explanations regarding the mounting of the rotating body.

[0039] The rotating body can also have means for energy transmission and / or means for position determination. In this regard, reference is made to the explanations regarding the corresponding means of the carrier body. The device, in particular the rotating body and / or the carrier body, can further have at least one contact element for establishing electrical contact between a carrier-body-side means for energy transmission and / or position signal transmission and a rotating-body-side means for energy transmission and / or position signal transmission. Preferably, the device has a first contact element for transmitting a potential at a first level and at least one further contact element for transmitting a potential at a further voltage level that is different from the first voltage level.In particular, the potential present at the positive pole of the at least one battery can be transmitted via the first contact element, and the potential present at the negative pole of the at least one battery can be transmitted via the further contact element. Such a contact element can be designed, for example, as a contact spring. The device can have further such contact elements for position signal transmission.

[0040] The contact element or a contact element on the rotating body side and a contact element on the carrier body side can be designed and / or arranged in particular in such a way that energy and / or signal transmission is also possible during a rotational movement of the rotating body.

[0041] The device is configured such that, in the assembled state, a drive force / torque generated by the drive device causes a rotary movement of the rotary body, which can then move a locking element of the door lock. For this purpose, the rotary body can actuate an element of the lock directly or indirectly in the assembled state - as explained above. For example, in the assembled state, the locking cylinder actuating element can be arranged in the receiving section of the rotary body. Such a rotary movement of the rotary body is also referred to below as a locking movement of the rotary body. A locking movement can then serve, particularly depending on the direction of rotation of the rotary movement, to open (unlock) the lock or close (lock) the lock.

[0042] According to a first alternative, a stator of the drive device can be attached to the support body, and the rotating body can have at least one section for accommodating at least one battery for supplying power to the drive device. This section is referred to below as the battery compartment. For the purposes of this invention, a battery refers to a power source. A battery can be a primary or secondary battery. For example, the battery can be a lithium battery.

[0043] According to a second alternative, the stator of the drive device is attached to the rotating body, and the support body can have at least one battery compartment. In this case, the stator is supported on the rotating body. During operation of the drive device, the stator rotates with the rotating body, while the at least one battery is arranged stationary relative to the support body.

[0044] It is possible for the device to comprise the at least one battery, which is then arranged in the battery compartment. If the battery is arranged in the battery compartment, in the first alternative, the battery rotates with the rotating body during a locking movement. The at least one battery can be arranged in the battery compartment in a removable or non-removable manner. The at least one battery can be rotationally symmetrical or non-rotationally symmetrical. The arrangement of several batteries in the battery compartment can also be a rotationally symmetrical arrangement, in particular with respect to a rotation axis of the rotating body.

[0045] Unless expressly stated otherwise or apparent from the context, the following statements refer to both the first and the second alternative.

[0046] The battery compartment can, in particular, be an internal volume of a hollow, in particular hollow-cylindrical, portion of the rotating or support body. The previously explained means for energy and / or signal transmission, which comprises, for example, at least one contact element, can be arranged on or in a wall and / or base portion of the battery compartment.

[0047] By arranging the stator of the drive device in / on the carrier body and the battery compartment in / on the rotating body, or vice versa, the space required for the device can be further reduced. This is because, if the stator is arranged in / on the carrier body, no space needs to be provided in the carrier body for one or more batteries. This allows the carrier body to be smaller than in smart locks, which provide for the arrangement of both the stator and the battery(ies) in the carrier body. The same applies to the second alternative, although in this case, no space needs to be provided in the carrier body for a stator.

[0048] Furthermore, the door fastening device has at least one element for mechanical connection to the carrier body or a carrier fastening element or the previously explained carrier fastening body.

[0049] According to the invention, the door fastening device has an adhesive surface for bonding the door fastening device to the door, in particular to a door element. An adhesive can be applied or arranged on this adhesive surface. In the bonded state, the door fastening device can be arranged in a fixed position relative to the door, in particular to the door leaf, and can be attached to the door.

[0050] Alternatively or additionally, the door fastening device comprises at least one element for establishing a clamping connection with the door, in particular a door element. Such an element can be, for example, a thread or a threaded bore into which clamping screws can be screwed to establish a clamping connection between the door fastening device and the door / door element, in particular the locking cylinder. Thus, a clamping screw screwed into the thread, in particular a tip of the clamping screw, can mechanically contact the door / door element, in particular the locking cylinder or another component of the door / another door element, and exert the clamping force.

[0051] Alternatively, the element for establishing the clamping connection can comprise a deformable portion of the door fastening device. This can be deformed, for example, by actuating an actuating element or by manual actuation in order to clamp the door fastening device to the door / door element.

[0052] In this case, the door fastening device can also include the actuating element. For example, the actuating element can be designed as a screw, wherein this screw can be arranged in or on the door fastening device, in particular in a threaded portion, such that upon actuation of the screw, the deformable portion is deformed to clamp the door fastening device to the door / door element. The deformable portion can then mechanically contact the door / door element.

[0053] The door fastening device preferably comprises a plurality of such elements. These are, in particular, arranged and / or designed to enable reliable and stationary fastening to the door, in particular to the locking cylinder. The arrangement and / or design of such elements can be adapted to the shape of a door element, in particular to the locking cylinder. The elements can, in particular, enable the device to be fastened to the door in such a way that the rotational axis of the rotating body corresponds to the rotational axis of the locking cylinder. In particular, elements for establishing a clamping connection can be arranged and / or designed to enable a three-point clamping connection between the door fastening device and the door.

[0054] The described door fastening device advantageously enables reliable and secure fastening as well as very quick installation of the device on a door, thus ensuring reliable function. Since the door fastening device can be attached to a variety of different doors, it also advantageously allows the device to have a wide range of applications.

[0055] Further alternatively or cumulatively, the door fastening device can have or form at least one element for producing a particularly detachable mechanical connection with the door.

[0056] Thus, the door fastening device can have at least one through-hole that serves to accommodate a screw for screwing the door fastening device to the door or a lock mounted in the door. In this case, the door or the locking cylinder can include at least one thread for receiving such a screw.

[0057] Particularly in the case of a plate-shaped door fastening device, it can have or form stiffening webs on one side, particularly on the side facing away from the door. Recesses can be arranged between these. Furthermore, the door fastening device can have the same thickness in the area of ​​these recesses and in the area of ​​the central through-opening described above, thereby minimizing undesirable uneven mechanical deformation during a production-related cooling process.

[0058] In a further embodiment, several elements for establishing a clamping connection with a locking cylinder are arranged around a central through-opening of the door fastening device. As explained, the central through-opening can serve to accommodate a portion of the locking cylinder and / or to accommodate a locking cylinder actuating element.

[0059] For example, threaded holes can be arranged around the central through-hole, wherein the threaded holes can be arranged and / or oriented in such a way as to ensure reliable attachment to a predetermined locking cylinder, e.g., to a locking cylinder used in the EU, Switzerland, the United Kingdom, the United States of America, Canada, the Nordic countries, or other countries. Thus, the arrangement and / or orientation of the threaded holes can be country-specific. The locking cylinder can, in particular, be a double cylinder, a knob cylinder, a round cylinder, or a half cylinder.

[0060] Center lines of two different threaded holes can enclose a predetermined angle that is different from 0° or 180°, but can also run parallel to each other.

[0061] This advantageously results in a reliable attachment to the door, in particular to a locking cylinder.

[0062] In a further embodiment, the at least one element for establishing a clamping connection is designed as a threaded bore. Such a threaded bore can be arranged in a side wall of a recess in a plate-shaped door fastening device. This advantageously results in simple production of an element for establishing a clamping connection, which enables reliable attachment to the door, in particular to a locking cylinder.

[0063] In a further embodiment, the central through-opening is arranged in a recess or depression in a surface of the door fastening device facing the door, wherein the at least one element for establishing a clamping connection is arranged outside the recess and / or in the region of a side wall delimiting the recess. This side wall can form a stiffening web. This advantageously results in a reliable attachment to the door, in particular to a locking cylinder.

[0064] In a further embodiment, the threaded bore extends from a side of the door fastening device facing away from the door to the side of the door fastening device facing the door, with a center line of the threaded bore extending from an opening of the threaded bore facing away from the door to an opening facing the door being oriented toward the recess. This advantageously results in a reliable fastening to the door, in particular to a locking cylinder.

[0065] In a further embodiment, the door fastening device has at least one section for receiving a fastening screw. Such a section can be designed, for example, as a (further) through-hole. This advantageously provides another option for attaching the door fastening device to the door. This advantageously increases the number of different doors to which the door fastening device can be attached, and thus the range of applications.

[0066] In a further embodiment, a door-facing opening of a threaded bore for establishing a clamping connection is arranged in a beveled side surface of a recess in the door-facing surface of the door fastening device. These recesses can be open, in particular, toward the door as well as toward the recess with the central through-opening. A surface of the beveled side surface can be oriented perpendicular to the centerline of the threaded bore. This advantageously results in simple production of the threaded bore and reliable clamping of the door fastening device to a locking cylinder.

[0067] In a further embodiment, the door fastening device comprises or forms at least one element for mechanical connection, which can also be referred to as a fastening element, to the carrier body, in particular a fastening body of the carrier body. Such an element for mechanical connection can be designed, for example, as a locking element.

[0068] For example, the support body, in particular the fastening body, can have or form at least one locking recess for receiving a locking element of the door fastening device. Of course, a reversed arrangement of the locking recess and the locking element is also possible. Such an element can also form a locking element, whereby the locking element prevents assembly when fastened.

[0069] This advantageously results in a reliable fastening of the carrier body of a device for actuating a lock to the door fastening device and thus to the door.

[0070] In a further embodiment, the door fastening device has or forms at least one guide element for guiding an assembly movement, wherein the device for actuation, in particular the carrier body, is fastened or can be fastened to the door fastening device by carrying out the assembly movement. The assembly movement can be a rotary movement. Such a guide element can be designed as a guide web, as a guide lug or as a guide groove or in another way. A guide element can be arranged or formed on a radial outer surface or side surface of the door fastening device. If the door fastening device has several such guide elements, these can be arranged or formed irregularly, in particular at different angular distances from one another, along the radial outer surface or the side surface of the door fastening device.

[0071] In particular, the guide element can be a component of a bayonet lock, which enables a quickly established and detachable mechanical connection of the carrier body to the door fastening device. Such a guide element can thus simultaneously also form an element for mechanical connection. The carrier body, in particular the fastening body explained above, can have corresponding fastening and / or guide elements, particularly at an end facing the door, which interact with the fastening and / or guide elements on the door fastening device side.

[0072] This advantageously results in a reliable and simple assembly of the carrier body of a device for actuating a lock on the door fastening device and thus on the door.

[0073] In a further embodiment, the door fastening device comprises or forms at least one element for enabling a disassembly movement. The disassembly movement can also be a rotational movement. In this case, the actuating device, in particular the carrier body, can comprise or form an element corresponding to this release element, which interacts with the release element.

[0074] For example, one of these elements can have a locking element, e.g. designed as a spring element, and the remaining element can have a receiving section for receiving the locking element in the assembled state. Then, for example, during the assembly movement, the device for actuation, in particular the carrier body, can be moved relative to the door fastening device in such a way that the locking element moves into the receiving section at the end of the assembly movement, i.e. in a predetermined relative position between the door fastening device and the carrier body. In this state, further relative movement between the carrier body and the door fastening device, in particular a disassembly movement, can be blocked. If the locking element is moved out of the receiving section, e.g. by actuation by a user, the disassembly movement can be released. The door fastening device or the carrier body can have an actuating element, e.g.a push button which is mechanically connected to the locking element or forms the latter, wherein a particularly manual actuation of the push button leads to the locking element being moved out of the receiving section.

[0075] The previously explained element for mechanical connection, in particular the previously explained locking element, can additionally form the release element.

[0076] This advantageously results in a reliable, but detachable, fastening of the device for actuating the lock to the door fastening device.

[0077] In a further embodiment, the door fastening device comprises or forms at least one stop element for limiting a relative movement, in particular the assembly movement, between the door fastening device and the actuating device, in particular the carrier body. This stop element can be formed in particular by the previously explained guide element for guiding the assembly movement, but also separately therefrom. This advantageously results in reliable and simple assembly of the device for actuating the lock on the door fastening device.

[0078] Further proposed is a cover element for a device for actuating a lock. The cover element can be arranged or attached, in particular, to a support body of the actuating device.

[0079] According to the invention, the cover element is configured such that it can be arranged or fastened to the device in such a way that a mechanical connection between the carrier body and a carrier fastening body, which can also be referred to as a carrier fastening element, or a door fastening device or a door is covered by the cover element.

[0080] The cover element can be hollow-cylindrical. In particular, an end of a connecting portion of the support body facing the door can be arranged in an internal volume of the cover element. This connecting portion will be explained in more detail below. An outer surface of the cover element can form a portion of the outer surface of the device. For example, an outer radius of the cover element can correspond to an outer radius of a portion of the device that forms a manual actuation surface for a user. The cover element can be mechanically connected to the support body in a rotationally fixed manner.

[0081] In a further embodiment, the cover element, in particular a lateral surface or a lateral section of a hollow cylindrical cover element, has or forms at least one through-opening.

[0082] For example, contact elements of a connection element for connecting an external energy source, which will be explained below, can extend through such a through opening or these contact elements can be accessible from the outside.

[0083] An element for enabling a disassembly movement or a locking element can also extend through such or another through opening, or such an element can be accessible or actuated from the outside.

[0084] The rotating body of the device for actuating the lock can have at least one receiving body for receiving the at least one battery and / or at least one actuating body, wherein the receiving body is arranged at least partially in an internal volume of the actuating body. The receiving body can be designed as a (first) hollow body and the actuating body can be designed as a (further) hollow body. The two bodies can form partial bodies of the rotating body. For the purposes of this invention, an at least partially arranged arrangement refers to a complete or only partial, i.e. incomplete, arrangement. An outer diameter of the receiving body can therefore be smaller than an inner diameter of the actuating body. It is possible for the receiving body to be arranged at an end of the rotating body facing the door or to form this door-facing end.The receiving body can then be arranged in a section of the interior volume of the actuating body facing the door or protrude into this section. The receiving body and / or the actuating body can be open towards one (front) side, in particular towards the side facing the door. Towards a (front) side facing away from the door, the receiving body and / or the actuating body can be at least partially closed, wherein the closing section forms a base section of the respective partial body. A base section of the receiving body can be arranged along the previously explained longitudinal axis of the device at a predetermined distance from a base section of the actuating body. The base sections can be oriented perpendicularly or substantially perpendicularly to the longitudinal axis. A further receiving volume can be formed between the base sections of the two partial bodies of the rotating body, which, for example,can serve to accommodate further elements of the device. For example, the stator, a control device and further components can be arranged in this further receiving volume. The receiving body and the actuating body can be designed as different bodies and mechanically connected to one another, preferably, but not necessarily, with a screw connection. The mechanical connection between the two partial bodies is a rotationally fixed connection. A section for receiving a locking cylinder actuating element (receiving section) or a lock actuating element different therefrom can be formed by the receiving body. The receiving body can also have an interface for the direct mechanical actuation of a lock element. The receiving body can also have the battery compartment. It is possible for the battery compartment and the receiving section orthe interface is arranged successively along the longitudinal axis of the device or the receiving body, wherein in particular the receiving section / interface is arranged closer to the door than the battery compartment in the assembled state. In this embodiment, the volumes of the battery compartment and the receiving section / interface can be spatially separate volumes that do not overlap. However, it is also possible for the volumes of the battery compartment and the receiving section / interface to overlap; in particular, the volume of the receiving section / interface can be arranged at least partially in a volume of the battery compartment. For example, several batteries can be arranged in the battery compartment, wherein these are arranged around the receiving section / interface. E.g.the receiving section / interface can be arranged between battery compartment sections in a cross-sectional plane oriented perpendicular to the longitudinal axis of the rotating body.

[0085] The receiving body can have means for energy and / or signal transmission, which in particular enable a transmission of the potentials present at the positive pole and the negative pole of the at least one battery, in particular to corresponding contact elements of the receiving body. The receiving body can also comprise these contact elements for transmitting these potentials to energy transmission means on the carrier body. The receiving body can also comprise an element for contact-based position determination, e.g. a contact element and means for energy transmission for transmitting a potential for position determination. This will be explained in more detail below. Such contact elements can, for example, be arranged on or in a base section of the receiving body. Preferably, at least two contact elements are arranged on or in the base section, wherein these serve to transmit different potentials.These contact elements can protrude from the base section into the receiving volume between the base sections of the receiving and actuating bodies, i.e., protrude from a surface of the base section of the receiving body facing away from the door. The contact elements can be arranged radially offset from one another, i.e., at different radial distances from the longitudinal or symmetrical axis of the receiving body. Furthermore, these contact elements can contact conductor tracks or segments in the carrier body. This will be explained in more detail below. The arrangement of at least some sections of the receiving body of the rotating body in the interior volume of the actuating body advantageously results in a space-saving design of the rotating body and thus of the device.

[0086] The carrier body of a device for actuating a lock can be arranged, at least in part, within an interior volume of the actuating body. In particular, the receiving body can be arranged in a first part of this interior volume, and the carrier body can be arranged in a further part of this interior volume. The further part can, in particular, comprise the previously explained section between the base sections of the two partial bodies of the rotating body. The drive device, in particular the stator and the rotor, can also be arranged in this interior volume, in particular in the further part, further in particular in the section between the base sections, of the partial body.

[0087] It is possible for a section of the support body to be arranged in a space between the casing sections of the partial bodies of the rotating body. This section of the support body can extend from an end facing away from the door to a door-side end of the support body. This section can in particular be formed by the hollow section of the support body with the first outer diameter. A further section of the support body can be arranged in the section between the base sections of the partial bodies. This further section of the support body can in particular have the fastening and / or bearing sections of the support body explained. The arrangement of the support body, at least in sections, in the interior volume of the actuating body also advantageously results in a space-saving design of the device.

[0088] The carrier body of a device for actuating a lock can be arranged, at least in sections, between an outer wall of the receiving body, in particular a casing outer wall of a receiving body designed as a hollow body, and an inner wall of the actuating body, in particular an casing inner wall of a receiving body designed as a hollow body. This can correspond to the explained arrangement of a section of the carrier body, in particular the previously explained hollow section, in an intermediate space between the casing sections of the partial bodies of the rotating body.This section of the carrier body can form a connecting section which, in the assembled state, connects further sections of the carrier body, in particular the previously explained base section of the carrier body and / or the section for fastening the stator, to the door and thus ensures stable fastening to the door, while at the same time advantageously enabling the device to be designed with little installation space. An end of the connecting section facing the door can be mechanically connected to the door or the door fastening device in the assembled state. The device can also comprise a cover element, in particular a hollow cylindrical cover element, for covering the mechanical connection between the carrier body and a carrier fastening element, which will be explained in more detail below, or the door fastening device or a door.In particular, the door-facing end of the connecting portion can be arranged in an interior volume of the cover element. An outer surface of the cover element can form a portion of the outer surface of the device. The cover element can be mechanically connected to the support body in a rotationally fixed manner.

[0089] A section of the rotating body of a device for actuating a lock can extend through a through-opening of the carrier body. The diameter of the through-opening can be smaller than a maximum outer diameter or a minimum outer diameter of the carrier body. The through-opening can be arranged in the previously explained bottom section of the carrier body. A diameter of this through-opening can be smaller than the outer diameter of this bottom section. In particular, a connecting section of the receiving body and the actuating body can extend through the through-opening for the particularly rotationally fixed connection of these bodies, wherein the bodies are mechanically connected to one another by this connecting section. The connecting section can comprise a connecting means such as the previously explained screw. The connecting section of the partial bodies can, for example,connect the base section of the receiving body to the base section of the actuating body and for this purpose extend, for example, from a surface of the base section of the receiving body facing away from the door to a side of the base section of the actuating body facing the door, in particular along the longitudinal axis of the device. It is possible for the rotating body to be mounted on the support body in the region of this connecting section, in particular via a ball bearing. This does not preclude the rotating body from additionally being mounted in the region of a further section on the support body. In particular, a manual actuation section of the rotating body can be mounted on a further section of the support body via a plain bearing.

[0090] This advantageously results in a very space-saving design of the device, while at the same time ensuring that elements can be arranged in the internal volume of the device and thus protected from external influences.

[0091] The rotating body of a device for actuating a lock can have a cover element for the receiving body. The cover element can be arranged on a front side of the receiving body facing the door and thus cover or at least partially close the interior volume of the receiving body, in particular the battery compartment, on this front side. Thus, the interior volume of the receiving body can be arranged between the previously explained base section of the receiving body, the casing section of the receiving body, and the cover element. The cover element can be mechanically connected to the receiving body, preferably in a detachable and / or rotationally fixed manner. It is possible, for example, for the cover element and / or the receiving body to have (corresponding) locking elements for mechanical connection to one another.The device, in particular the cover element and / or the receiving body, can also have at least one spring element which clamps the cover element and the receiving body together when fastened to one another. Alternatively or cumulatively, such a spring element can be arranged or designed such that it fixes the at least one battery arranged in the interior volume of the receiving body, thereby ensuring not only a stable arrangement of the battery but also reliable electrical contact with the battery. The cover element advantageously results in an arrangement of the at least one battery in the battery compartment that is protected from external influences, e.g. dirt or moisture, and thus a reliable functioning of the device.

[0092] The cover element can have a section for receiving a locking cylinder actuation element or an interface for mechanically actuating a lock element. A receiving section or an interface can be designed, in particular, as a recess, in particular a blind hole-like recess, in the region of a surface of the cover element facing the door. The recess can, in particular, be a slot-shaped recess. The structural integration of the receiving section / interface into the cover element advantageously results in a very compact design of the device with a low installation space requirement, while simultaneously ensuring a protected arrangement of the at least one battery.

[0093] At least one section of the rotating body of a device for actuating a lock can form a manual actuation section for actuation by a user. This section can be a hollow section of the rotating body and, in particular, can be formed by the actuating body body explained above. This section can be closed on an end face facing away from the door, wherein this end face can form the end face of the device facing away from the door. A haptic actuating element and / or an optical output element of the device can be arranged on this end face, as explained in more detail below. An actuating surface can, in particular, partially or completely encompass the outer circumferential surface of the rotating body, in particular of the actuating body, or can be formed by it. This outer circumferential surface can also form the outer circumferential surface of the device.A user can manually actuate the manual actuation section, particularly in the area of ​​the actuating surface, and, for example, exert a torque on the rotating body. This torque can generate a locking movement.

[0094] The support body and other parts of the rotating body can be arranged, at least in sections, within an interior volume of the manual actuation section. Additional elements of the device, e.g., the drive mechanism, a control device, and other elements, can also be arranged within the interior volume. This advantageously results in a device that also enables the performance of a manual closing process with very limited installation space requirements.

[0095] The drive device of a device for actuating a lock can be designed as an external rotor motor. The external rotor motor can be designed, for example, as a brushless direct current motor (BLDC motor) or as a permanent magnet synchronous motor (PMSM motor). In this case, the drive device can comprise a stator with a predetermined number of n stator windings, where n can be, for example, 12. The stator windings can be electrically interconnected in a star connection, preferably in a double star connection. The drive device can further comprise a predetermined number m of magnetic elements, where m can be, for example, 14, which can be arranged on a rotor of the external rotor motor. The rotor can be rotatably mounted on or relative to the stator and / or on or relative to the carrier body via a bearing device as described above.The rotor and stator can—as previously explained—be arranged in the interior volume of the device, in particular in the manual actuation section, and furthermore, in particular, in the section between the base sections of the two partial bodies of the rotating body. Configuring the drive device as an external rotor motor advantageously results in a very compact design of the drive device, which can simultaneously reliably generate the torque required for the locking movement, which in turn results in reliable operation of the device.

[0096] A device for actuating a lock can comprise a gear for transmitting the movement of a rotor of the drive device to the rotating body or the carrier body. The gear can be designed, in particular, as a planetary gear. Preferably, the gear is designed as a coupling gear, in particular as a reduced coupling gear. Particularly preferably, the gear is designed as a Wolfrom gear. However, other embodiments of the gear are also conceivable. For example, the gear can be designed as a harmonic drive gear, which can also be referred to as a stress wave gear, harmonic gear or sliding wedge gear, or as a gear transmission. The gear can comprise a plurality of gear elements, in particular gears and / or gear rings. For example, the gear can comprise a sun gear, at least one ring gear and at least one epicyclic gear (planetary gear).The gear mechanism, in particular the gear elements, can - as explained above - be arranged in the internal volume of the device, in particular of the manual actuation section and further in particular in the section between the bottom sections of the two partial bodies of the rotating body.

[0097] It is possible for the rotor of the drive device to have or form a sun gear, or for the sun gear to be attached to the rotor. A first ring gear of the transmission can be mechanically connected, in particular in a rotationally fixed manner, to the carrier body. A further ring gear of the transmission can be or become mechanically connected to the rotating body, in particular in a rotationally fixed manner. Preferably, however, the further ring gear is mechanically connected to the rotating body via a clutch. The sun gear and the ring gears can be designed as externally or internally toothed gear rings. It is also possible for a bearing device, in particular a ball bearing, to be arranged between different ring gears of the transmission in order to reduce friction during a relative movement of the ring gears to one another, in particular when engaging and disengaging a clutch.

[0098] Planetary or epicyclic gears of the transmission can be rotatably mounted on an epicyclic gear carrier. The epicyclic gear carrier, in turn, can be arranged rotatably relative to the carrier body. At least one epicyclic gear pair, which can comprise two different epicyclic gears, can be rotatably mounted on the epicyclic carrier, with the two epicyclic gears of the pair being mounted on the epicyclic gear carrier so as to be rotatable about the same axis of rotation. A first epicyclic gear of a pair can mesh with the first ring gear, and a further epicyclic gear of the pair can mesh with the further ring gear. The epicyclic gears of a pair can be connected to one another in a rotationally fixed manner. It is also conceivable for both epicyclic gears of a pair to be formed by a one-piece epicyclic gear body.

[0099] The planetary gears of a pair can be helical-toothed planetary gears. This advantageously leads to reduced noise emissions during actuator-supported operation of the device. The number of teeth of the first and second planetary gears can be selected such that noise emissions during operation are reduced. In particular, the number of teeth of the first planetary gear is different from the number of teeth of the second planetary gear. The number of teeth of the first planetary gear can be smaller, but preferably larger, than the number of teeth of the second planetary gear. To reduce or avoid the axial forces generated by the helical gearing during actuator-supported operation, the helix angle of the first planetary gear can be different from the helix angle of the second planetary gear. This cancels out axial forces and relieves the load on the gear during actuator-supported operation.In particular, the helix angle of the second planetary gear can correspond to an inverted helix angle of the first planetary gear. This can mean that the helix angle of the helical gearing of the second planetary gear relative to a common reference axis, e.g., the rotational axis of the planetary gears, corresponds to the inverted value of the helix angle of the helical gearing of the first planetary gear or the difference between 180° and the value of the helix angle of the helical gearing of the first planetary gear.

[0100] Alternatively, it is possible for the rotor of the drive device to have the planetary gear carrier or for the planetary gear carrier to be attached to the rotor, wherein the transmission does not include a sun gear.

[0101] The gearing advantageously enables the conversion of a torque generated upstream of the drive device into a torque for the rotating body that is dimensioned to execute the locking movement. This enables reliable operation of the device.

[0102] A device for actuating a lock can comprise a clutch for establishing a separable connection between a rotor of the drive device and the rotating body or the carrier body. In the disengaged state, no force / torque can be transmitted from the rotor to the rotating body via the clutch. In the engaged state, a force / torque can be transmitted from the rotor to the rotating body via the clutch. In the engaged state, an actuator-supported locking movement can be carried out, since a torque can be transmitted from the drive device to the rotating body. Actuator-supported in the sense of this invention can mean that the drive torque for carrying out the locking movement is generated at least partially or exclusively by the drive device.

[0103] In the disengaged state, a manual locking movement can be enabled, which can be performed without the user having to overcome a blocking force / torque of the drive mechanism not operated during the manual locking movement, since such a blocking torque is not transmitted from the drive mechanism to the rotating body. Thus, a freewheel clutch is provided that enables simple manual actuation of the device, whereby, in particular, the rotating body can be decoupled (and thus freely rotated) from the drive mechanism during manual actuation.

[0104] The clutch can comprise a plurality of clutch elements that can be moved relative to one another to establish the engaged state and to establish the disengaged state. The clutch, in particular the clutch elements, can - as explained above - be arranged in the internal volume of the device, in particular of the manual actuation section and further in particular in the section between the base sections of the two partial bodies of the rotating body. For example, the clutch can comprise a first clutch element, e.g. a first hollow ring, and a further clutch element, e.g. a further hollow ring, wherein these clutch elements each have a gear section. The first clutch element can be or become mechanically connected to the rotor and the further clutch element to the rotating body, in particular the manual actuation section.The clutch elements can be designed as external, internal, or lateral gears, and in particular as helically toothed gear rings. Furthermore, the clutch can include a return element; this will be explained below.

[0105] In the engaged state, the coupling elements can be arranged relative to one another such that the gear sections mesh with one another. In the disengaged state, the coupling elements can be arranged relative to one another such that the gear sections do not mesh with one another. A relative movement for coupling can be oriented along or against the longitudinal axis of the device. Accordingly, a relative movement for disengaging can be oriented against or along this longitudinal axis. However, the relative movement can also have a different orientation. If the coupling element is annular, this orientation can in particular be oriented normal to the (circular) area enclosed by the coupling element.

[0106] The clutch can have at least one engagement element for establishing an engaged state in actuator-supported operation of the device. This can be arranged and / or designed such that the engaged state is established automatically or independently when the drive device is operated to generate a locking movement. It is conceivable, for example, that the at least one engagement element is mechanically coupled to the rotor and arranged and / or designed such that it generates a relative movement between the clutch elements (clutch movement) from a rotational movement of the rotor to establish the engaged state. Thus, the engagement element can be mechanically coupled to the rotor, in particular via the explained gear. This clutch movement can be generated, for example, by the at least one engagement element.The engagement element can at least partially and / or temporarily convert a torque generated by the drive device into a drive force for generating the clutch movement. It is particularly possible for the previously explained further hollow ring of the transmission to comprise or form the engagement element. In particular, several engagement elements can also interact with one another to generate this clutch movement.

[0107] The clutch can also have precisely one or more return elements for establishing a disengaged state. This return element can be designed as a spring element, in particular as a wave spring, disc spring, wire bending spring, or a spring element designed differently therefrom, or can comprise precisely one such spring element or several such spring elements. The at least one return element can be arranged, for example, between the coupling elements that are movable relative to one another. It is thus conceivable that precisely one wave spring or wire bending spring, or several, in particular three, wave springs or wire bending springs, are arranged between such coupling elements.

[0108] The clutch can in particular be designed as an automatic clutch. This can mean that clutch elements are arranged and / or designed and interact with one another in such a way that the engaged state is established and / or remains established upon or after the start of operation of the drive device for carrying out an actuator-supported locking movement. For this purpose, the rotational movement of the rotor can cause a relative movement between the clutch elements of the clutch to establish and / or maintain the engaged state. During this relative movement (engaging movement), a restoring force of the restoring element can be overcome. Furthermore, such an automatic clutch can also comprise the explained restoring element, which generates a force to establish the disengaged state. For example,The disengaged state is established at or after the end of operation of the drive device for performing an actuator-assisted locking movement. The corresponding relative movement (disengaging movement) can be generated entirely or partially by the restoring force of the restoring element.

[0109] The automatic clutch can, however, be designed in such a way that this disengaging movement can only take place in a released state. To establish the disengaged state, for example, after the locking movement has ended, the drive device can be operated to release the disengaging movement. For this purpose, the drive device can be operated in such a way that the rotating body is rotated in a predetermined direction of rotation, which is in particular oriented opposite to the direction of rotation of the previously ended locking movement. Through this rotary movement, the relative movement to establish the disengaged state can be released and brought about by the restoring force generated by the restoring element. Alternatively, the disengaged state can also be established by a user actuating the manual actuation section in such a way that the rotating body is rotated in the aforementioned predetermined direction of rotation.

[0110] The provision of a clutch advantageously simplifies manual actuation of the device to execute a locking movement, since—as previously explained—no locking torque needs to be overcome. The wave spring clutch design advantageously enables a very space-saving design of the clutch.

[0111] The device for operating a lock may comprise the door fastening element or the door fastening device. The door fastening element and corresponding advantages have already been explained above.

[0112] The carrier body and / or the rotating body of a device for actuating a lock can have at least one element for transmitting energy from a battery to the drive device. Alternatively or cumulatively, the carrier body and / or the rotating body can have at least one element for transmitting energy from a connection element of the device for connecting an external energy source to the drive device and / or to a battery arranged in the battery section. Such means for transmitting energy have already been explained above and can, in particular, be designed as conductor tracks. It is possible for the control device to also be supplied with energy via the at least one element for transmitting energy from a battery to the drive device.

[0113] It is thus conceivable that the drive device and / or a battery are supplied with energy via the connection element if an external energy source is connected to the device via the connection element. This energy can thus be used to operate the drive device and / or to charge the battery. The connection element can be designed for wired or wireless energy transmission, e.g., for inductive or infrared-based energy transmission. An external energy source can be detachably connected to the connection element.

[0114] It is also conceivable for the connection element, and thus the device, to be permanently connected to an external power source, e.g., via a power cable. In this case, the energy for operating the drive device can be provided partially or entirely by the external power source. With such a power supply, the battery can serve as an energy buffer, providing, for example, energy to operate the drive device in the event of a failure of the external power supply.

[0115] The means for energy transmission can, for example, comprise at least one slip ring which is arranged in or on the carrier body, in particular in or on a side of the previously explained base section of the carrier body facing the door.

[0116] Preferably, several electrically insulated slip rings, in particular two slip rings, with different radii can be arranged in or on the carrier body, whereby these can serve in particular for the transmission of drive energy. However, it is of course also conceivable for the slip rings to be arranged in or on the rotating body, and for the carrier body to have contact elements for contacting the slip rings. Furthermore, the means for energy transmission can comprise conductor tracks that are embedded at least partially in the carrier body.

[0117] A potential present at each of the two poles of the at least one battery can then be transmitted via these slip rings. For this purpose, these slip rings can be contacted by the previously explained contact elements of the rotating body, wherein this contact is also maintained during a rotational movement of the rotating body. These slip rings can in particular be designed as complete slip rings. A charging potential can then also be transmitted to a pole of the at least one battery, in particular a positive pole, via a first slip ring, which serves to transmit the positive potential. The charging potential can in this case be provided by an element on a circuit board of the device, wherein the charging potential is generated, for example, from a potential present at the previously explained connection element.The connection element can thus comprise a first contact element for contacting a positive potential of the external energy source and a further contact element for contacting a negative pole of the external energy source. The first contact element of the connection element can be electrically connected to a connection element on the circuit board via means for energy transmission, whereby this connection is not routed via one of the slip rings. A charging voltage can then be generated by an element on the circuit board and transmitted to the first slip ring. The further contact element of the connection element can be electrically connected to a further slip ring, which serves to transmit the negative potential, via means for energy transmission. This slip ring can then be connected to a connection element on the circuit board via further means for energy transmission.

[0118] The carrier body and / or the rotating body of a device for actuating a lock can comprise at least one element for contact-based position determination. The contact can, in particular, be an electrical contact. The contact-based position determination can, in particular, be a sliding contact-based position determination. Thus, the carrier body and / or the rotating body can comprise elements arranged and / or configured such that, at least in angular positions from selected angular ranges, during a rotational movement of the rotating body, electrical contact is established between an element on the rotating body side and an element on the carrier body side. Preferably, in angular positions from angular ranges different from the selected angular ranges, no electrical contact can be established between the elements. The angular positions or angular ranges can refer to a predetermined reference angle.Furthermore, contact states of the elements, in particular a state with established contact and a state with no contact, and in particular their temporal progression during the rotational movement, can be determined. These can be determined, for example, as a function of a temporal progression of a potential of an element for contact-based position determination, e.g., by the control device. Depending on the contact state or a temporal progression, a direction of rotation and a change in angular position can be determined by the rotational movement. A current angular position can then be determined with reference to a reference angle, in particular both for an actuator-supported and a manually performed locking movement.

[0119] A position-determining element can be designed in the same way as or by means of an energy-transmitting element. It is conceivable that an energy-transmitting device could also serve for position determination.

[0120] For example, the device can comprise, as element(s) for position determination, one or more further slip rings arranged electrically insulated from one another, in particular two further slip rings, with different radii, which can in particular be arranged in or on the carrier body. A radius of one of these slip rings can be different from the radii of the slip rings for drive energy transmission, in particular smaller than or larger than these radii, but also lie between these radii. The radii of the slip rings are in particular selected such that slip rings for drive energy transmission and slip rings for position determination are arranged electrically insulated from one another.

[0121] A slip ring for position determination can be an incomplete slip ring. An incomplete slip ring comprises at least one ring segment that can be contacted to establish an electrical contact and at least one electrically non-contactable ring segment in which no electrical contact can be established with the slip ring (insulating section). Thus, the device can include at least one additional slip ring, in particular an incomplete slip ring, for determining the position of the rotating body.

[0122] In particular, at least one contactable segment, preferably a plurality of contactable segments, of at least one incomplete slip ring can be arranged on the door-facing surface of the base section of the rotating body, wherein an incomplete slip ring consists of at least one contactable segment or a plurality of electrically insulated contactable segments. The at least one contactable segment and at least one insulating section can be arranged along a circular line on the surface, wherein a center line of the at least one segment and a center line of the at least one insulating section are arranged on the circular line.

[0123] If such an incomplete slip ring comprises a number of s segments, where s can be equal to or greater than 1, a length of a circular arc-shaped center line of a segment and a length of a circular arc-shaped center line of an insulating section adjacent along the circular line can each correspond to the total length of the circular line divided by 2 x s, or a central angle of the respective center line can be 360° / (2 x s). Segments of several, particularly preferably exactly two, incomplete slip rings with different radii are preferably arranged on the surface of the base section of the rotating body facing the door. The segments of different slip rings can be arranged along circular lines with different radii. Segments of different slip rings can be arranged at an angular offset from one another, in particular with an angular offset corresponding to half a segment length.This can mean that a radial line along which a segment, in particular a segment start or end, of a first incomplete slip ring is arranged is arranged with an angular offset from a radial line immediately adjacent in the circumferential direction, along which a segment, in particular a segment start or end, of another incomplete slip ring is arranged. This angular offset can be (-)360° / (4 xs).

[0124] The device can comprise, as a further element for determining the position, at least one contact element for contacting the contactable segments of an incomplete slip ring, which can be arranged in particular on the rotating body. For each incomplete slip ring of the device, the device can comprise, for example, a number t of contact elements, where t can be equal to or greater than 1. Preferably, the number s of segments is an integer multiple of the number t of contact elements. Several contact elements can be arranged along a circular line with the same radius as the circular line of the incomplete slip ring, in particular uniformly.

[0125] If the device comprises a plurality of slip rings, the at least one contact element for contacting the at least one segment of a first incomplete slip ring (first contact element) can be arranged at an angular offset to the at least one contact element for contacting the at least one segment of a further incomplete slip ring (further contact element), in particular with an angular offset of 360° / (2 xs), where s - as explained above - can be one or an integer multiple of one. This can mean that a radial line along which the first contact element, in particular its center point, is arranged, is arranged at an angular offset to a radial line immediately adjacent in the circumferential direction, along which the second contact element, in particular its center point, is arranged.

[0126] During a rotary motion, contact elements can move along a circular path. During the motion, a contactable segment can enter a contacted state, in which it is electrically contacted by a contact element, or a non-contacted state, in which it is not contacted by a contact element. Thus, a contacting or non-contacting state can occur for a contact element during the motion.

[0127] These states can be determined by evaluating electrical signals, in particular a potential, e.g. by the control device. For example, a potential in the contacted or contacting state can be different from the potential in the non-contacted or non-contacting state, where the potential can be, for example, a potential applied to the contact element or to the segment. By determining the contact states, in particular the temporal sequence of the different contact states that arise during a rotary movement, a direction of rotation and an angle of rotation of the rotary movement can be determined. This in turn enables the current angular position of the rotary body to be determined starting from a zero angle position determined, for example, during calibration or a reference run, even during or after a locking movement carried out by manual actuation.

[0128] The energy transmission means enable reliable energy transmission and thus operation of the drive device even during rotation of the rotating body. They can also enable rotational position determination.

[0129] In particular, this enables reliable rotational position determination with very low energy consumption.

[0130] Furthermore, the device can comprise at least one of the following elements or devices: the previously explained connection element for connecting an external energy source, at least one optical output element, at least one light source, at least one haptic actuating element, at least one control device for controlling the operation of the device, at least one communication device.

[0131] An external energy source connected via the connection element can charge the at least one battery. It is possible for the device to have at least one further energy storage device, e.g. for supplying energy to the control device, in addition to the battery for supplying energy to the drive device. In this case, this further energy storage device can also be charged via the connection element. The connection element can - as explained above - comprise a plurality of contact elements for contacting different voltage potentials of the external energy source, e.g. a first contact element for contacting a positive potential and a further contact element for contacting a negative potential. This can correspond, for example, to the potential at a negative pole of the battery. The connection element can furthermore have at least one magnetic element for magnetically fastening the external energy source oran external energy transfer element such as a charging plug.

[0132] The optical output element can be used to output an optically detectable signal, in particular to a user. At least part of this optical output element can be arranged on a front side of the device facing away from the door. Thus, the output element can be arranged, for example, in or on the rotating body, preferably in or on the base section of the actuating body of the rotating body.

[0133] The device can also comprise at least one light-guiding element. Radiation generated by a light source can be guided by this at least one light-guiding element to the optical output element, through which the radiation is then output as an optically detectable signal. The at least one light-guiding element can be arranged in a stationary manner on the carrier body, in particular in or on a circuit board, wherein the circuit board is arranged in a stationary manner on the carrier body. If the device comprises a plurality of light-guiding elements, the radiation guided by each of the light-guiding elements can be guided to the optical output element. The light-guiding element can in particular be curved or have a curved section for beam guidance. The light-guiding element can have an incident radiation section, wherein radiation is radiated into the light-guiding element via the incident radiation section, e.g. from a light source.Furthermore, the light-guiding element can have an emission section through which radiation exits the light-guiding element to the optical output element. A central center line of the light-guiding element, which connects the incident radiation section and the emission section, can be curved.

[0134] The light-guiding element can be a ring or ring-segment-shaped element. The at least one light-guiding element can also comprise different segments, which can be optically separated segments. This can mean that radiation radiated into a first segment is not transmitted into a further segment. Thus, different radiations, in particular from different light sources, can be transmitted separately through the different segments. If the light-guiding element is (partially) ring-shaped, the different segments can each have central angles of the same size, but preferably central angles of different sizes. In other words, the length of the circular arcs formed by the different segments can be the same or different from one another. E.g.a first segment may have a central angle that is k times the central angle of another segment, where k may be an integer and may be, for example, 3.

[0135] As an alternative to forming a light-guiding element with different segments, the device can comprise a plurality of light-guiding elements, which can be optically separated from one another. These light-guiding elements can also be partially annular, in particular with identical or different center angles, in accordance with the preceding embodiments.

[0136] The at least one light source can be designed as an LED, for example, but different designs of the light source are also conceivable. The light source can be arranged in a fixed location on the carrier body, in particular in or on the circuit board. The device preferably comprises a plurality of light sources, wherein at least one of the light sources is arranged such that radiation can be radiated into a first light-guiding element or into a first segment of a light-guiding element. At least one further light source can be arranged such that radiation can be radiated into a further light-guiding element or into a further segment of the light-guiding element.

[0137] The haptic actuating element can be used to generate an actuating signal through manual actuation by a user. This actuating signal can be, for example, a control signal for a locking movement. It can be arranged, in particular, on a front side of the device facing away from the door. Thus, the actuating element can be arranged, for example, in or on the rotating body, preferably in or on the base section of the actuating body of the rotating body, or form a part, in particular a central part, of this base section.

[0138] The at least one haptic actuating element can be designed, in particular, as a pushbutton. The haptic actuating element is preferably mechanically connected to the rotating body in a rotationally fixed manner. The optical output element described above can have a central through-opening or recess in which the haptic actuating element can be arranged.

[0139] By actuating the haptic actuating element, a switching element of the device, in particular a switching element arranged on the circuit board, can be actuated to generate a switching signal. For this purpose, the device can comprise a force transmission element, in particular a spring-mounted one, which transmits a pressure force exerted on the haptic actuating element to the switching element. Thus, when actuated by a user, the push button and the force transmission element can execute a switching movement, during which the switching element is actuated. The spring-mounted mounting can exert a restoring force on the force transmission element and the push button. This can lead to a movement of the force transmission element and the push button whose direction is opposite to the switching movement direction, whereby the actuation of the switching element is canceled.Furthermore, the spring-loaded mounting can also provide a clearly perceptible haptic feedback for the user. However, spring-loaded mounting is not mandatory, so the force transmission element can also be non-spring-loaded.

[0140] The control device can be arranged in a stationary manner on the carrier body, in particular in or on the circuit board. It can be designed as a computing device, which in particular can comprise at least one microcontroller or an integrated circuit or can be designed as such. The control device can, for example, control the generation of a stator voltage, wherein the device can comprise at least one element for generating this stator voltage. This element can also be arranged in or on the circuit board. The control device can also control the generation of a charging voltage for the at least one battery, wherein the device can comprise at least one element for generating this charging voltage. This element can also be arranged in or on the circuit board. The control device can also process a signal generated by actuating the haptic operating element and, depending on this generated signal, e.g.generate a control signal. The control device can also control the operation of the at least one light source and / or control communication of the device with at least one external device, e.g. a mobile terminal such as a mobile phone or a server device. Data or signal transmission serving the communication can take place via the at least one communication device. The at least one communication device can be designed in particular for wireless communication. This can take place, for example, according to one or more standards, e.g. according to the Bluetooth standard, a WLAN standard, an NFC standard, a Z-Wave standard and / or another radio standard. Such a communication device can also be arranged in or on the circuit board.

[0141] The components of the device can be made of various materials. Thus, the following elements can be made of plastic, particularly a glass-fiber-reinforced polymer or glass-fiber-reinforced thermoplastic such as PA, PBT, or PPA: the receiving body of the rotating body, which serves to transmit the positive potential; a cover element of the rotating body; a carrier fastening element; the carrier body; and the planetary gear carrier. However, other materials such as carbon fibers or glass beads can also be mixed into the plastic as an alternative or in addition to glass fibers.

[0142] The following elements can also be made of plastic, in particular of polymethyl methacrylate, polyamide, in particular polyamide 12, polyoxymethylenes or styrene-acrylonitrile copolymer: the optical output element, the light-guiding element.

[0143] The following elements can also be made of plastic, in particular polyoxymethylene (POM), especially a homopolymer POM: a coupling element, a planetary gear, and a connecting element for connecting the receiving body and the actuating body. A carrier element for a light-guiding element can also be made of plastic, in particular a polycarbonate. A cover element of the carrier body can also be made of plastic, in particular an acrylonitrile-butadiene-styrene copolymer. A non-conductive material of the connection element, which can be arranged in particular between the contact elements explained for their electrical insulation, can be made of plastic, in particular PPS.

[0144] The following elements can also be made of metal, in particular sintered metal, steel, preferably stainless steel, or non-ferrous metals such as aluminum or bronze: the actuating body of the rotating body, the push button, a coupling element, in particular a coupling ring gear, and the rotor. These specifications are purely exemplary; other materials may also be selected.

[0145] A device having the features of one of the embodiments described in this disclosure advantageously forms a smart lock with low weight, space requirements, and energy consumption, yet enables rapid execution of the locking movement and thus a short locking time. It also enables reliable, particularly actuator-assisted, actuation of a lock over a wide range of rotation angles. The noise level during actuator-assisted operation is low. Furthermore, the smart lock is suitable for a variety of locking cylinders and locks, as well as for a variety of relative arrangements between the door handle and the door lock. A further advantage is the simple and quick installation of the proposed smart lock.

[0146] Further described is a method for operating a device for actuating a lock according to one of the embodiments described in this disclosure, wherein the drive device is operated to generate a rotary movement of the rotary body. In the assembled state, in which the rotary body is mechanically connected via an actuating element, e.g., a lock cylinder actuating element, or directly to a lock element, this rotary movement can then generate / cause a locking movement of the lock. In particular, the control device can generate a corresponding control signal for the drive device. The control device can also generate the stator voltages, in particular their temporal profiles, such that the desired rotary movement is generated. The rotary movement then serves to open or close the lock. The control signal can be generated as a function of an input signal. E.g.,An input signal can be generated by means of the haptic actuating element. The input signal can also be generated by a device external to the device, e.g., by a mobile device. In this case, the input signal can, in particular, be an encrypted input signal that is encrypted for a specific device. In particular, the device can be controlled only or also by input signals that are encrypted for a specific device, thereby ensuring that control is only by authorized users. It is also possible for the control device to determine a rotational position of the rotating body. This has already been explained above. The control device can then control the drive device depending on the determined rotational position.

[0147] The control device can generally control the operation of the device, in particular also a calibration operation, and can carry out necessary or desired functions for this purpose, e.g. safety functions such as a function for preventing overcurrent.

[0148] The device is thus configured to perform a method according to one of the embodiments described in this disclosure.

[0149] Also described is a method for mounting a device for actuating a lock on a door fastening device. In this case, an assembly movement, in particular a rotary movement, can be carried out. This allows the device to be mounted on the door fastening device. For example, the device can be placed on the door fastening device with the end facing the door and then the assembly movement can be carried out. In a method also described for dismantling the device for actuating a lock from the door fastening device, a dismantling movement, in particular a rotary movement opposite to the assembly rotational movement, can be carried out. This allows the device to be dismantled from the door fastening device. For example, the dismantling movement can be carried out and the device can then be removed from the door fastening device.Before the disassembly movement is carried out, it can be released, e.g. by actuating a corresponding element.

[0150] A method for mounting a door fastening device on a door is also described. The door fastening device can be glued to the door using the adhesive surface, whereby adhesive can be applied to this surface for this purpose. Alternatively or additionally, the door fastening device can be clamped to the door, in particular a door element, using an element for establishing a clamping connection.

[0151] The invention is explained in more detail using exemplary embodiments. The figures show: Fig. 1 a perspective view of a device for operating a lock from a side facing away from the door, Fig. 2 a perspective view of a device for operating a lock from a side facing away from the door, Fig. 3 a longitudinal section through a device for operating a lock, Fig. 4 a perspective view of a carrier body, Fig. 5 a further perspective view of a first hollow body of a rotating body, Fig. 6 a cross-section through a device for actuating a lock in the region of a supporting section of a carrier body, Fig. 7 shows a further cross-section through a device for actuating a lock in the region of a supporting section of a carrier body, Fig. 8 a detailed section through a device for actuating a lock in the region of a supporting section of a carrier body, Fig. 9 a perspective view of a backdrop ring, Fig. 10 a perspective view of a first coupling ring, Fig. 11 a perspective view of another coupling ring and a coupling hollow body, Fig. 12 a detailed section of the device for operating a lock in the area of ​​the coupling rings, Fig. 13 is a plan view of a circuit board of the device, Fig. 14 a detailed section through the device for operating a lock in the area of ​​the printed circuit board, Fig. 15 is a perspective view of a device for actuating a lock in a further embodiment from a side facing away from the door, Fig. 16 a longitudinal section through the Fig. 15 shown device, Fig. 17 is a perspective view of a door fastening device according to the invention from a side facing the door, Fig. 18 is a perspective view of a door fastening device according to the invention from a side facing away from the door, Fig. 19 a longitudinal section through a door fastening device according to the invention in a further embodiment.

[0152] In the following, identical reference symbols designate elements or features with identical or similar technical properties. Not all figures necessarily depict all elements of the device.

[0153] Fig. 1 shows a perspective view of a device 1 for operating a lock from a side facing away from the door. The device 1, which can also be referred to as a smart lock, is essentially cylindrical. The device 1 has a lateral surface 2 as well as a front side 3 facing the door and a front side 4 facing away from the door. The device 1 is fastened with the front side 3 facing the door to a door (not shown) or to a locking cylinder (also not shown) of the door, either directly or via a door fastening device designed in particular as a fastening plate 5 (see e.g. Fig. 17). However, it is also conceivable to attach the device 1 to the door in a different way or to integrate it into the door. The device 1 comprises a carrier body 6 (see Fig. 3) and a rotating body 7. The device 1 also comprises a cover element 13 according to the invention of the carrier body 6, which has a connecting section 18 ( Fig. 3) of the carrier body 7 with the door or the door fastening device. An outer surface of the cover element 13 forms part of the outer surface 2 of the device 1. On the end face 3 facing away from the door, the device 1 has a haptic actuating element designed as a push button 8, which is arranged in a central area of ​​the end face 3 facing away from the door. An outer surface of this push button 8 can be a concave, i.e. inwardly curved, surface. Also in Fig. 1 shows an optical output element 10, which comprises or is formed by a light output element 11 with an annular section. This output element 10 is arranged on the side 3 of the device 1 facing away from the door. The push button 8 is arranged in a recess surrounded by the annular section of the light output element 11. The output element 10 serves to emit an optical signal.

[0154] A part of the outer surface 2 of the device 1, which is formed by the rotating body 7, forms a manual actuation element 12 of the device 1. A user can rotate the rotating body 7 by actuating the area of ​​this part of the outer surface 2 and thus - as explained in more detail below - execute a manual locking movement. However, the rotating body 7 can also be actuated by operating a drive device (not shown in Fig. 1) of the device 1, especially when an actuator-supported locking movement is carried out. Further in Fig. 1 shows a locking element 9, which can be designed in particular as a locking button, for mechanically connecting the support body 6 to the door or a door fastening device. The function of this locking element 9 is described in relation to Fig. 17 is explained in more detail.

[0155] Also shown is a longitudinal axis L of the device 1. This can correspond to a rotational axis of the rotating body 7. However, it is not mandatory that the rotational axis of this longitudinal axis L correspond to the device 1; the axes can also be offset from one another. An arrow symbolizes an orientation of the longitudinal axis L, which is oriented from the end face 3 facing the door to the end face 4 facing away from the door.

[0156] If reference is made below to a side facing the door, this refers to a side that faces the end face 3 of the device 1 facing the door. A side facing away from the door refers to a side that faces the end face 4 of the device 1 facing away from the door. An inner surface or radial inner surface can refer to a surface that faces the longitudinal axis L and whose normal vector is oriented parallel to a radial direction. An outer surface or radial outer surface can refer to a surface that faces away from the longitudinal axis L and whose normal vector is also oriented parallel to a radial direction. The radial direction is perpendicular to the longitudinal axis L and oriented away from it. The explained meanings apply unless expressly explained otherwise or unless otherwise indicated by the context. The device 1 further comprises a connection element 46 for connecting an external energy source, e.g. via a charging plug.The connection element 46 has a pin-shaped first contact element 63 and a second annular disk-shaped contact element 64. The first contact element 63 serves to contact a positive potential of the energy source, the second contact element 64 to contact a negative potential. Of course, reversed polarity / contacting is also conceivable. The contact elements 63, 64 are arranged on the casing surface 2 of the device 1, in particular in the region of the cover element 13, and can be contacted from the outside. The contact elements 63, 64 can extend through a first through-opening 109 in a casing section of the cover element 13. Alternatively or cumulatively, the contact elements 63, 64 can be contacted through the first through-opening 109. The first through-opening 109 is formed as a recess in the end face of the casing section facing away from the door.In other words, the first through-opening 109 is not completely surrounded by the casing section. The contact elements 63, 64 are electrically insulated from one another. The connection element 46 is designed as a magnetic connection element and can, for example, have at least one magnetic element (not shown) for magnetically attaching an external connection element, e.g., the charging plug, to the connection element 46. It is conceivable that the first and / or second contact elements 63, 64 are also designed to be magnetic.

[0157] It can also be seen that the locking element 9 extends through a further through-opening 110 in the casing section of the cover element 13 or is arranged in this.

[0158] However, it is of course also possible that the first and / or the further through-opening 109, 110 can be completely surrounded by the casing section and are thus not open towards the end side facing away from the door or towards the door.

[0159] Fig. 2 shows a perspective view of the Fig. 1 from a side 3 facing the door. An internal volume 14 of the device 1 can be seen. In the internal volume 14 are arranged, among other things, partial bodies of the rotating body 7, in particular a receiving body designed as a first hollow body 15, which can also be referred to as the inner body of the rotating body 7. This first hollow body 15 has a Fig. 2 shown cover element 16, which has an internal volume 17 (see Fig. 3) of the first hollow body 15. This inner volume 17 of the first hollow body 15 serves to accommodate at least one battery 27 (see Fig. 3) for supplying energy to a drive device of the device 1 and thus forms a battery compartment of the device 1. The cover element 16 is detachably connected to a casing section of the first hollow body 15, in particular via a locking connection. This can be established via interacting locking elements. In a state in which the cover element 16 is fastened to the casing section, it forms a ceiling section of the first hollow body 15. It can also be seen that the cover element 16 has a recess 38 on an upper side facing the door, which recess serves to receive a locking cylinder actuating element, in particular a locking cylinder pin. The locking cylinder actuating element can be arranged in this recess, wherein it is connected to the cover element 16 in a rotationally fixed manner, e.g., in a form-fitting manner. The recess thus forms a section 38 for receiving a locking cylinder actuating element. Fig. 2 shows that the recess is slot-shaped.

[0160] Also visible are various components or sections of the carrier body 6. Fig. 2 a carrier fastening element 21, which is provided with a connecting section 18 (see Fig. 3) is mechanically rigidly connected. This connecting section 18 of the carrier body 6 is arranged between a radial outer wall of the first hollow body 15 and a radial inner wall of an actuating body of the rotary body 7, which is designed as a further hollow body 19, and serves for the mechanical connection of the carrier body 6 to the door or the door fastening device. The further hollow body 19 forms a further partial body of the rotary body 7. This carrier fastening element 21, which is essentially ring-shaped or hollow-cylindrical, has locking elements for the mechanical connection to the connecting section 18 (see Fig. 3). The locking elements of the carrier fastening element 21 can be designed as locking recesses 22 (see Fig. 3) into which locking lugs 23 of the connecting section 18 can engage to establish the mechanical connection. The locking recesses 22 can be formed on a radial outer side (i.e., on an outer surface of the casing) of the carrier fastening element 21. Furthermore, the carrier fastening element 21 has bayonet recesses 45 on an inner surface of the casing for guiding an assembly movement, which are used to receive and guide the movement of guide elements of the door or a door fastening device, in particular a fastening plate 5 (see Fig. 17). The function of the bayonet recesses 45 in conjunction with guide elements of a mounting plate 5 is explained below. However, such guide elements can also be arranged or formed on the door or a lock. The bayonet recesses 45 and the guide elements of the mounting plate 5, designed as guide webs 24 (see Fig. 17) form elements of a bayonet lock for mechanically connecting the carrier body 6 to the fastening plate 5. In the illustrated embodiment, the carrier fastening element 21 has three bayonet recesses 45 along the inner surface of the casing, wherein the bayonet recesses 45 are arranged unevenly along the inner surface of the casing. In particular, an angular distance between a first and a second recess 45 can be different from an angular distance between the second and a third recess 45 and / or different from an angular distance between the third and the first recess 45. This can ensure that the carrier body 6 can only be fastened to the fastening plate 5 with a predetermined orientation relative to the latter. The recesses 45 are thus arranged and / or designed in such a way that a poka-yoke principle is provided with regard to the mounting on the fastening plate 5.Also visible are manufacturing-related grooves in the inner surface of the casing. The bayonet recesses 45, in particular, allow the carrier body 6 to be plugged onto the mounting plate 5, with the guide webs 24 being inserted into the bayonet recesses 45. During this plugging process, a locking cylinder pin or a key can also be inserted into the receiving section 38.

[0161] By performing a rotational movement (assembly movement) of the carrier body 6, the carrier body 6 and the fastening plate 5 can then be connected to one another. The bayonet recesses 45 simultaneously form stop elements for this assembly movement. Thus, the carrier body 6 can only be rotated relative to the fastening plate 5 up to a predetermined angular position. Once this angular position is reached, a desired orientation is set between the carrier body 6 and the fastening plate 5, and thus also between the carrier body 6 and a locking cylinder. The state in which this desired orientation is set can also be referred to as the assembled state of the carrier body 6. In this state, the carrier body 6 is fixedly attached to the locking cylinder or to the door via the fastening plate 5.

[0162] Also shown is a notch 65 in the carrier fastening element 21, which forms an optically detectable marking for a user and makes it possible to align the device 1 relative to the fastening plate 5 for carrying out the assembly movement in such a way that the guide webs 24 can be plugged on and inserted into the bayonet recesses 45. The fastening plate 5 thus has a corresponding notch 66. If a user positions the device 1 relative to the fastening plate 5 before plugging on in such a way that the notches 65, 66 are aligned or overlap in a common projection plane, which can be oriented perpendicular to the explained longitudinal axis L, the plugging on and insertion of the guide webs 24 into the bayonet recesses 45 is made possible.

[0163] Fig. 3 shows a longitudinal section through a device 1 for actuating a lock. Shown is the carrier body 6, which has a connecting section 18, a base section 25, a support section 20, and a cover element 13. The connecting section 18 is hollow-cylindrical and has a first outer diameter. The connecting section 18 is open towards a front side facing the door and towards a side remote from the door. The base section 25 is arranged in the inner volume of the connecting section 18. The base section 25 divides the inner volume of the connecting section 18 into two sub-volumes. The first hollow body 15 of the rotary body 7 is arranged in a first sub-volume facing the door. At least a part of the support section 20 of the carrier body 6 is arranged in a second sub-volume facing away from the door. Shown are the Fig. 2 already explained locking lugs 23 and locking recesses 22 for fastening the connecting section 18 to the carrier fastening element 21. It can be seen that the carrier fastening element 21, in addition to the locking recesses 22, also has locking lugs that engage in locking openings in the casing section of the connecting section 18. The locking lugs of the carrier fastening element 21 can be formed by sections that delimit the locking recesses 22. Also shown is a fastening plate 5 (see also Fig. 17), wherein the carrier fastening element 21 is mounted on the fastening plate 5.

[0164] In a door-facing surface of the floor section 25, conductor tracks 26a, 26b, 26c, 26d (see Fig. 4) are arranged, which serve to transmit voltage potentials from batteries 27 to a drive device.

[0165] The support section 20 is also hollow-cylindrical and protrudes from a surface of the base section 25 facing away from the door in the direction away from the door. The support section 20 comprises a first sub-section 20a and a further sub-section 20b. In the direction away from the door, i.e. along the longitudinal axis L, the first sub-section 20a merges into the further sub-section 20b. Both an outer and an inner diameter of the first sub-section 20a are larger than the corresponding diameters of the further sub-section 20b. An outer diameter of the sub-sections 20a, 20b is each smaller than the outer diameter of the connecting section 18. In the support section 20, in particular in the further sub-section 20b, a stator 28 (see Fig. 6) of the drive device can be fastened to the support body 6. Likewise, a printed circuit board 29 can be fastened in the support section 20 to the support body 6 and / or to the stator 28, e.g., via a soldered and / or adhesive connection. It is conceivable, for example, that an assembly comprising the printed circuit board 29 and the stator 28 fastened to the printed circuit board 29 is pre-assembled and then fastened to the support section 20.

[0166] Also shown is a rotating body 7, which—as already explained above—has a first hollow body 15 (inner body) and a further hollow body 19 (outer body), wherein the further hollow body 19 can also be referred to as the actuating body. The hollow bodies 15, 19 are formed as separate components and are mechanically connected. The mechanical connection is established in particular via a screw 30. The connecting section of the hollow bodies 15, 19 extends through a through-opening 31 of the carrier body 6, in particular the through-opening formed by the support section 20 and a through-opening 31 in the base section 25.

[0167] Also shown is a threaded portion 98 of the first hollow body 15, which protrudes from a central region of a top side of a base portion 33 of the first hollow body 15 facing away from the door and extends through the through-opening 31 of the base portion 25 into the interior volume of the support portion 20. The threaded portion 98 has a thread accessible from the side facing away from the door, into which the screw 30 can be screwed. The rotating body 7 is rotatably mounted on the support body 6, in particular on an inner surface of the first partial portion 20a of the support portion 20, via a ball bearing 32.

[0168] The first hollow body 15 serves to accommodate at least one battery 27, in particular a battery stack formed from several batteries 27, wherein these batteries 27 are thus rotatably mounted on the carrier body 6. The at least one battery 27 is arranged in an inner volume 17 of the first hollow body 15. This inner volume 17 thus forms the battery compartment. In the illustrated embodiment, the rotating body 7 comprises a cover element 16, which is fastened to a casing section of the first hollow body 15. The first hollow body 15 further has the base section 33. On this base section 33, contact springs (see Fig. 5) are arranged contact elements 85a, 85d for establishing electrical contact between the battery terminals and the conductor tracks 26a, 26b, as well as contact elements also designed as contact springs for electrically contacting conductor track segments 26c, 26d, which enable the position of the rotating body 7 to be determined. This will be explained below. Also shown are fixing elements designed as rubber mats 99, between which the battery stack is pressed and thus clamped in the interior volume 17 when the cover element 16 is fastened. Also shown is the section 38 designed as a recess in the cover element 16 for receiving a lock cylinder actuating element. Fig. 3 shows two rubber mats 99, with a first rubber mat 99 being arranged on the side of the interior volume 17 facing the door and a second rubber mat 99 being arranged on a side of the interior volume 17 facing away from the door. Of course, embodiments with only one rubber mat 99 are also conceivable, which can be arranged either on the side of the interior volume 17 facing away from the door or on the side facing the door. A rubber mat 99 can have through-openings, e.g., for energy transmission means.

[0169] The first hollow body 15 is arranged, at least in sections, within an internal volume 34 of the further hollow body 19. The shell sections of the hollow bodies 15, 19 are arranged parallel and at a predetermined radial distance from one another, wherein—as already explained above—the connecting section 18 of the carrier body 6 extends, at least in sections, between an outer wall of the shell section of the first hollow body 15 and an inner wall of the shell section of the further hollow body 19. A section of the further hollow body 19, in particular an outer wall of the shell section, forms a manual actuation surface for a user. Thus, the further hollow body 19 forms a manual actuation element 12, which was already explained above. An outer radius of the further hollow body 19 is equal to an outer radius of the cover element 13.The interior volume 34 enclosed by the further hollow body 19 is open on an end face facing the door, i.e., unlocked. On an end face facing away from the door, the further hollow body 19 has a base section 35. This base section 19, in turn, has an actuating element designed as a push button 8, which forms a central section of the base section 35 and can be actuated from the outside by a user, in particular, can be pressed toward the door. Pressing the push button 8 can serve to generate a control signal.

[0170] Furthermore, the rotating body 7 comprises a light emitting element 11, which has the function already described with reference to Fig. 1. The light emitting element 11 is connected to a door-facing surface of the base portion 35 of the further hollow body 19, in particular glued thereto. The annular portion of the light emitting element 11 extends through the base portion 35 and thus forms an optical output element 10. The light emitting element 11 is part of a coupling hollow body 101. This is designed as a hollow body open towards the side facing the door, wherein the coupling hollow body 101 has or forms a further coupling ring 78 on an end face facing the door. On an end face facing away from the door, the coupling hollow body 101 has a base portion, wherein the light emitting element 11 forms this base portion or a part thereof.

[0171] The device 1, in particular the rotating body 7, comprises a fastening sleeve 102 that protrudes from the coupling hollow body 101 in a central region of the door-facing surface of the base portion of the coupling hollow body 101. The fastening sleeve 102 and the coupling hollow body 101 can be formed as separate components or as a single piece. An outer diameter of the fastening sleeve 102 tapers toward the door-facing end face 3 of the device 1. An inner volume of the fastening sleeve 102 serves to accommodate the screw 30. It is shown that the fastening sleeve 102 has radially inwardly projecting stop webs 103 for a screw head in the inner volume, wherein the screw head can be arranged in a part of the inner volume of the fastening sleeve 102 facing away from the door. The threaded portion 98 of the first hollow body 15 can be arranged in a part of the inner volume facing away from the door. The partial volumes can be separated by the stop webs 103.The fastening sleeve 102 can further comprise locking elements for the mechanical connection of the push button 8, which can be inserted into the interior volume from the side facing away from the door and can be mechanically and, in particular, rotationally fixedly secured to the fastening sleeve 102 by means of a locking connection. For this purpose, the push button 8 can comprise at least one corresponding locking element. In the attached state, the push button 8 covers the interior volume of the fastening sleeve 102, in particular with a screw 30 arranged therein.

[0172] When the device 1 is manually actuated, a user can generate a rotary movement of the manual actuation element 12 and thus of the further hollow body 19 by applying a torque. Due to the mechanical connection to the first hollow body 15, this also rotates, and thus also a locking cylinder actuation element arranged in a rotationally fixed manner in section 38. The rotating body 7 thus executes a manually generated locking movement. Depending on the direction of rotation, a door lock can thus be set to an open or closed state.

[0173] During automatic or actuator-assisted actuation of the device 1, a drive device can generate a torque. This torque is transmitted to the rotating body 7, in particular the further hollow body 19, via a gear mechanism (explained in more detail below) and a clutch (also explained in more detail below), generating a corresponding rotational movement, i.e., an actuator-assisted locking movement. Analogous to manual actuation, this can rotate a locking cylinder actuating element arranged in a rotationally fixed manner in section 38.

[0174] In Fig. 3 further shows the connecting element 46. Contact elements 63, 64 of the connecting element 46 are arranged on a connecting circuit board 67. This is arranged on the carrier body 6, in particular in a section of the connecting section 18. In Fig. 3 shows that the connecting circuit board 67 is attached, in particular glued, to an inner surface of the connecting section 18. The connecting circuit board 67 can have conductor tracks that contact the contact elements 63, 64. The connecting section 18 has a through-opening 68 through which the contact elements 63, 64 arranged on the connecting circuit board 67 extend.

[0175] Fig. Fig. 4 shows a perspective view of a carrier body 6 of a device 1 from a side facing the door, wherein in particular the conductor tracks 26a,...,26d arranged in a carrier body 6, in particular a bottom section 25 of the carrier body 6, and designed as slip rings or slip ring segments are shown. These are accessible from a side of the bottom section 25 facing the door. Thus, they can be contacted by contact elements 85a, 85d (see Fig. 5) of the rotating body 7 are electrically contacted.

[0176] The device 1 comprises, in particular, two complete slip rings 26a, 26b, i.e., not divided into segments arranged electrically insulated from one another. A first complete slip ring 26a serves to transmit a negative potential, which is applied to a negative pole of a battery 27 or a battery stack. The further complete slip ring 26b serves to transmit a positive potential, which is applied to a positive pole of the battery 27 or the battery stack. The electrical connection of the poles to these slip rings 26a, 26b is established via the contact elements 85a, 85b explained above. The complete slip rings 26a, 26b can be connected via further conductor tracks 69 to connections on a printed circuit board 29 (see Fig. 13). These conductor tracks 69 can be embedded in a material of the carrier body 6 and guided from the slip rings 26a, 26b to the printed circuit board 29. It is shown that a diameter of the first slip ring 26a is smaller than a diameter of the second slip ring 26b and the first slip ring 26a is arranged within the second slip ring 26b. It is possible for the second contact element 64 of the connection element 46 to be electrically connected to the first complete slip ring 26a via a conductor track, which can in particular be arranged in / on the connection printed circuit board 67. However, the first contact element 63 of the connection element 46 can be connected directly to a connection element of the printed circuit board 29 via a conductor track and not be guided via a slip ring 26a, 26b.

[0177] Also shown are nine segments of an incomplete third slip ring 26c and nine segments of an incomplete fourth slip ring 26d. Each of these incomplete slip rings 26c, 26d comprises the nine segments shown. For clarity, only one segment per slip ring 26c, 26d is provided with a reference symbol. Of course, more or fewer than the nine segments shown may be present. The segments are arranged along a circular path and separated from one another by insulating sections arranged between the segments along this circular path.

[0178] A diameter of the second slip ring 26b is smaller than a diameter of the third slip ring 26c, and a diameter of the third slip ring 26c is smaller than a diameter of the fourth slip ring 26d. The third slip ring 26c is arranged within the fourth slip ring 26d, and the second slip ring 26b is arranged within the third slip ring 26c. A potential of these slip rings 26c, 26d can also be connected via conductor tracks 69 to connection elements on the printed circuit board 29 (see Fig. 2) be conducted.

[0179] The segments of the third and fourth slip rings 26c, 26d are arranged equiangularly, i.e., at equal angular intervals, along a circular path. However, the segments of the two slip rings 26c, 26d are arranged at an angular offset from one another, in particular with an angular offset of half the segment length. A radial line along which a segment, in particular a segment start or end, of the third slip ring 26c is arranged is arranged at an angular offset from a radial line directly adjacent in the circumferential direction, along which a segment, in particular a segment start or end, of the fourth slip ring 26d is arranged.This angular offset can be in a range from 0° (exclusive) to 20° (inclusive) with respect to a mathematically positive direction of rotation about a longitudinal axis of the carrier body 6 and can preferably be 10° if this longitudinal axis is oriented from the side facing the door to the side of the carrier body 7 facing away from the door.

[0180] The segments can be connected by corresponding contact elements 85c, 85d (see Fig. 5) of the rotating body 7, whereby various contact states can occur. In particular, segments of both slip rings 26c, 26d can be contacted by contact elements 85c, 85d (first contact state). One segment(s) of the third slip ring 26c, but no segment of the fourth slip ring 26d, can be contacted by contact element(s) 85c (second contact state). One segment(s) of the fourth slip ring 26d, but no segment of the third slip ring 26c, can be contacted by contact element(s) 85d (third contact state). No segment of the third slip ring 26c and no segment of the fourth slip ring 26d can be contacted by contact elements 85c, 85d (fourth contact state). During a rotational movement of the rotating body 7, these states can change over time, whereby this change of state can also be dependent on the direction of rotation.The contact states can be determined by evaluating electrical signals, in particular a potential. For example, a potential of a segment contacted by contact elements 85c, 85d can be different from a potential of a segment not contacted by contact elements 85c, 85d. By determining the contact states, in particular the temporal sequence of the various contact states occurring during a rotary movement, a direction of rotation and an angle of rotation of the rotary movement can be identified. This in turn enables the determination of a current angular position of the rotary body 7, starting from a zero angle position determined, for example, during a calibration or reference run. This can then be used to control the movement, e.g.if an angular position to be set for setting the closed state of the lock or an angular position of the rotary body 7 to be set for setting the open state of the lock is to be set, in particular actuator-supported.

[0181] Fig. Figure 5 shows a perspective view of a first hollow body 15 of a rotary body 7 of a device 1 from a side facing away from the door. Shown is a surface of a bottom section 33 of the first hollow body 15 facing away from the door. The first hollow body 15 has contact elements 85a, 85d designed as contact springs, in particular as spring tongues. Contact elements 85a of a first set of three contact elements (first contact elements 85a) serve to contact the Fig. 4 shown first complete slip ring 26a. Contact elements 85b of a second set of three contact elements (second contact elements 85) serve to contact the Fig. 4. Contact elements 85c of a third set of three contact elements (third contact elements 85c) are used to contact the Fig. 4 shown segments of the third incomplete slip ring 26c. Contact elements 85d of a fourth set of three contact elements (fourth contact elements 85d) serve to contact the Fig. 4. The contact elements 85a, 85d are each arranged along a circular path with a predetermined angular offset between contact elements 85a, 85d adjacent along the circular path, in particular with an angular offset of 120°. Of course, more or fewer than the three contact elements 85a, 85d shown can be present per set. The angular offset can - as previously explained - depend on the number of segments present and the number of contact elements 85a, 85d present. The radii of the circular paths differ from one another, with the radius of a first circular path along which the first contact elements 85a are arranged being smaller than the radius of a second circular path along which the second contact elements 85b are arranged.The radius of the second circular path, in turn, is smaller than the radius of a third circular path along which the third contact elements 85c are arranged. The radius of this third circular path is in turn smaller than the radius of a fourth circular path along which the fourth contact elements 85c are arranged. Each of the first contact springs 85a is arranged with a third contact spring 85c along a common radial line with respect to a longitudinal axis of the rotating body 7. Likewise, each of the second contact springs 85b is arranged with one of the fourth contact springs 85d along a common radial line. However, the radial lines along which a pair of second and fourth contact springs 85b, 85d are arranged are arranged at an angular offset from a radial line immediately adjacent in the circumferential direction, along which a pair of first and third contact springs 85a, 85c are arranged.This angular offset can be 360° divided by the number of segments, i.e. 40° in the illustrated embodiment, with respect to a mathematically positive direction of rotation about the longitudinal axis of the first hollow body 15, if this longitudinal axis is oriented from the side facing the door to the side of the first hollow body 15 facing away from the door.

[0182] Fig. 6 shows a cross-section through a device 1 for actuating a lock in the region of a support section 20 of a carrier body 6. A stator 28 of a drive device with 12 stator windings 52 is fastened to an outer surface of the support section 20, in particular a further partial section 20b of the support section 20. The stator windings 52 are wound around pole shoes 53 of the stator 51, which protrude radially from a central section 74 of the stator 51, wherein the pole shoes 53 are arranged with equal angular spacings between adjacent pole shoes 53 along a circular line. The central section 74 has a through-opening through which the support section 20 and the rotating body 7 extend. For the sake of clarity, only one stator winding 52 and one pole shoe 53 are provided with a reference numeral.

[0183] Also shown is a rotor 54 of the drive device with permanent magnets 55. The drive device is designed as an external rotor motor, in particular as a brushless external rotor motor, wherein the stator 51 is arranged in an internal volume enclosed by the rotor 54, which is designed as a hollow ring or hollow cylinder. The permanent magnets 55 are arranged on an inner surface of the rotor 54 facing the pole pieces 53. The permanent magnets 55 have alternating polarities along the circumferential direction of the rotor 54. For the sake of clarity, only one permanent magnet 55 is provided with a reference symbol.

[0184] The rotor 54 forms a sun gear of a planetary gear and has teeth 57 on an outer surface thereof, which mesh with gears 58 of a first stage of the gear. In other words, the rotor 54 is designed as an externally toothed gear rim or ring gear. The gears 58 of this first stage are each rotationally fixed to a gear 59 of a second stage (see, for example, Fig. 7), wherein a gear pair consisting of connected gears 58, 59 is rotatably mounted on a planetary gear carrier 60. The gears 58, 59 of a gear pair are designed as helical gears, wherein a helix angle of the gear 59 of the second stage is inverted with respect to a helix angle of the gear 58 of the first stage. Furthermore, the number of teeth of the gear 58 of the first stage is greater than the number of teeth of the gear 59 of the second stage. A gear pair can, in particular, be designed as an integral component or in one piece. The gears 58 of the first stage additionally mesh with a hollow ring 75 designed as an internally toothed gear ring.This hollow ring 75 is mechanically connected in a rotationally fixed manner to the support body 6, in particular to an inner surface of a hollow-cylindrical section 95 of the connecting section 18, which projects beyond the base section 25 of the support body 6 in the direction away from the door and delimits the previously explained second partial volume facing away from the door. This is also particularly evident in . Fig. 8. Thus, the gears 58 of the first stage are arranged between the hollow ring 75 and the rotor 54.

[0185] Fig. Fig. 7 shows a further cross section through a device 1 for actuating a lock in the region of the support section 20 of the support body 6, which in relation to the Fig. 6 is offset along the longitudinal axis L of the device 1 towards the end face 4 facing away from the door. Fig. Figure 7 shows that the gears 59 of the second stage mesh with a link ring 62 formed as an internally toothed gear ring, which is part of a coupling of the device 1. This link ring 62 is rotatably mounted relative to the carrier body 6.

[0186] Fig. Figure 8 shows a detailed section through the device 1 for actuating a lock in the region of the support section 20 of the carrier body 6. It can be seen that a shaft 61 is rotatably mounted in / on the planetary gear carrier 60, with the gears 58, 59 of a gear pair being non-rotatably attached to the shaft 61. The planetary gear carrier 60 is designed as a hollow ring and is rotatably arranged in the inner volume 34 of the further hollow body of the rotating body 19.

[0187] A rotational axis and central center axis of the shaft 61 is oriented parallel to the rotational axis of the rotating body 7. The gears 58 of the first stage are arranged at an end of the shaft 61 facing the door, and the gears 59 of the second stage are arranged at an end of the shaft 61 facing away from the door. It can also be seen that a door-facing end section of the rotor 54 is rotatably mounted via a ball bearing 56 on the carrier body 6, in particular on an outer surface of a first partial section 20a of the support section 20 of the carrier body 6.

[0188] It can also be seen that the guide ring 62 is rotatably mounted on the hollow ring 75 via a ball bearing 51, wherein the ball bearing 51 is arranged between mutually facing outer surfaces of the rings 62, 75. The guide ring 62 is arranged behind the hollow ring 75 along the longitudinal axis L of the device 1 in a direction oriented from the side 3 facing the door to the end face 4 facing away from the door.

[0189] The device 1 further comprises a first coupling ring 77 and a further coupling ring 78, which can be part of a hollow coupling body 101. This first coupling ring 77 is designed as a laterally toothed gear ring, with teeth arranged on a side surface of the coupling ring 77 facing away from the door. The further coupling ring 78 is also designed as a laterally toothed gear ring, with teeth arranged on a side surface of the coupling ring 77 facing the door. In a coupled state, the teeth of the two coupling rings 77, 78 mesh. In a disengaged state, the teeth of the first coupling ring 77 do not engage with the teeth of the further coupling ring 78, and the two coupling rings 77, 78 do not mesh with each other. The teeth are formed by beveled side surfaces of the coupling rings 77, 78. The first coupling ring 77 is rotatably mounted on the link ring 62.In addition, the first coupling ring 77 is mounted on the link ring 62 for linear movement. A movement axis of this linear movement is oriented parallel to the longitudinal axis L of the device 1.

[0190] Fig. 9 shows a perspective view of a link ring 62 from a side facing away from the door. Fig. Figure 10 shows a perspective view of a first coupling ring 77 from a side facing away from the door. The first coupling ring 77 has radially inwardly projecting coupling webs 79 on an inner surface of the casing. On a side surface facing the door, the first coupling ring 77 has coupling lugs 80 projecting from this side surface in a direction toward the door.

[0191] A casing outer surface 105 of this first coupling ring 77 is of stepped design. As a result, a radius of a first section 105a of this casing outer surface 105 facing away from the door is smaller than a radius of a first section 105b of this casing outer surface 105 facing the door. Due to the stepped design, a contact surface 106 for the, for example, Fig. 12 is formed. Also visible are guide lugs 107 for clamping and locking a wave spring 84 on the first coupling ring 77. These guide lugs 107 protrude radially outward from the first section 105a and are arranged at a distance from the contact surface 106, wherein a section of the wave spring 84 can be clamped between the contact surface 106 and the guide lugs 107. The first coupling ring 77 also has a web 108 which protrudes from the contact surface 106 and also protrudes radially outward from the first section 105a. This web 108 also serves to lock the wave spring 84, which is slotted. The wave spring 84 is then arranged on the first coupling ring 77 such that the web 108 is arranged in the slot of the wave spring 84.

[0192] A side surface of the link ring 62 facing away from the door has recessed sections 81 and coupling sections 82, wherein a width of the link ring 62 in the region of the recessed sections 81 is smaller than in the region of the coupling sections 82, wherein the width is measured along a central axis of the link ring 62. A recessed section 81 is arranged between each two coupling sections 82 adjacent along a circumferential direction. The link ring 62 also has transition sections 83, which are arranged along the circumferential direction between a coupling section 82 and a recessed section 81, as well as between this recessed section 81 and the next coupling section 82. In these transition sections 82, the width of the link ring 62 decreases or increases. For the sake of clarity, only two transition sections 83 are provided with a reference symbol.

[0193] If the rotor 54 is set in rotation, the sun gear of the transmission rotates and meshes with the gears 58 of the first stage. The planetary carrier 60 performs a circular movement along the inner surface of the hollow ring 75. The rotation of the gears 58 of the first stage leads to a rotation of the gears 59 of the second stage, which mesh with the link ring 62. This generates a rotation of the link ring 62. During this rotation, the recessed sections 81, the coupling sections 82, and the transition sections 83 move relative to the coupling webs 79, with a coupling web 79 being arranged between two coupling sections 82 adjacent along the circumferential direction.During this rotary movement, on the one hand, a rotary movement of the link ring 62 is transmitted to the first coupling ring 77, and on the other hand, the first coupling ring 77 is displaced towards the further coupling ring 78, so that an engaged state is created. The coupling webs 79 contact the side surface of the link ring 62 facing away from the door, even in the region of the recessed sections 81, so that even with such contact, a rotary movement can be transmitted from the link ring 62 to the first coupling ring 77. However, as explained in more detail below, the first coupling ring 77 is in a disengaged state with respect to the further coupling ring 78 when the coupling webs 77 contact the side surface in the region of the recessed sections 81. Such a rotary movement of the first coupling ring 77 in the disengaged state is limited by the coupling lugs.80, which during the rotational movement are connected to corresponding coupling lugs 36 (see . Fig. 3), which protrude from an end face of the connecting section 18 of the carrier body 6 facing away from the door. This blocks the rotational movement of the coupling ring 77, although the link ring 62 can continue to rotate and the coupling webs 77 are thus moved along the side surface of the link ring 62 into the region of a transition section 83. This displaces the first coupling ring 77 towards the further coupling ring 78, which simultaneously removes the stop state between the coupling lugs 80, 36 and allows the rotational movement of the first coupling ring 77 to be released again. In the engaged state, the rotational movement of the first coupling ring 77 is then transferred to the further coupling ring 78 and thus to the hollow coupling body 101. This is mechanically connected or fixed against rotation to the further hollow body 19 of the rotating body 7.forms part of this rotating body 7, so that it too is set in a rotary movement and thus an actuator-supported locking movement can be carried out. For disengaging, the drive device is operated in such a way that the link ring 62 is rotated by a predetermined angle counter to the direction of rotation of the immediately preceding rotary movement. Due to the resulting relative rotation between the link ring 62 and the first coupling ring 77, the coupling webs 77 are moved from the regions of the transition sections 82 into the regions of the recessed sections 81, whereby a disengaging movement of the first coupling ring 77 away from the further coupling ring 78 is released, so that a disengaged state is established. To establish the disengaged state, the device 1 comprises a wave spring 84 (see . Fig. 12), which is arranged between the coupling rings 77, 78 and which presses the first coupling ring 77 away from the further coupling ring 78.

[0194] Fig. Figure 11 shows a perspective view of a further coupling ring 78 and a coupling hollow body 101 from a side facing the door, wherein the further coupling ring 78 is a component of the coupling hollow body 101. The toothed section arranged on a side surface of the coupling ring 78 facing the door is visible. On an outer surface of the casing, the coupling hollow body 101 has radially projecting webs 96. These serve for the rotationally fixed attachment of the further hollow body 19 of the rotating body 7 to the coupling hollow body 101. In particular, the coupling hollow body 101 can be inserted into the further hollow body 19, wherein the webs 96 are arranged in corresponding recesses in the inner casing surface. This then creates a rotationally fixed connection. A bottom section of the coupling hollow body 101 forms the light emitting element 11 (see Fig. 3). Further shown is the Fig. 3 already explained fastening sleeve 102. The bottom section of the coupling hollow body 101 has through-openings 104 arranged around a foot section of the fastening sleeve 102. In the assembled state, the actuating webs 90 extend through these through-openings 104 (see Fig. 14).

[0195] Fig. 12 shows a detailed section of the device 1 for actuating a lock in the area of ​​the coupling rings 77, 78. Shown is the wave spring 84, which is arranged between the explained contact surface 106 and a door-facing end face of the further coupling ring 78. If the first coupling ring 77 is moved toward the further coupling ring 78 as previously explained to establish the engaged state, the wave spring 84 is clamped between the coupling rings 77, 78. To perform this engagement movement, a spring force of the wave spring 84 must be overcome. In the clamped state, the wave spring 84 exerts a restoring force on the first coupling ring 77.However, this restoring force only generates a disengaging movement of the first coupling ring 77 away from the further coupling ring 78 when this disengaging movement is released as also explained above, in particular when the coupling webs 79 are located in recessed sections 81 of the side surface of the first coupling ring 77 facing away from the door.

[0196] In summary, a gear of the device comprises the rotor 54, the gear wheels 58, 59, the link ring 62 and the hollow ring 75. The link ring 62 is simultaneously part of a coupling of the device 1, wherein the coupling additionally comprises the first and the further coupling ring 77, 78 as well as the wave spring 84.

[0197] Fig. 13 shows a plan view of a surface of a printed circuit board 29 of the device 1 facing away from the door. Electronic or electrical components of the device 1 can be arranged on or in the printed circuit board 29, which in Fig. 13 are shown schematically. One of these components can, in particular, be a control device of the device 1, which can be designed, for example, as a microcontroller or integrated circuit. Further components can form elements of a communication device of the device 1.

[0198] On the illustrated surface of the circuit board 29, a ring-shaped or disc-shaped support element 86 is arranged, in which light-guiding elements 87a, 87b are embedded. Fig. 13 shows emission sections of these light-guiding elements 87a, 87b. A first light-guiding element 87a is partially annular and has a center angle from a range of 120° (exclusive) to 0° (exclusive). A further light-guiding element 87b is also partially annular, wherein the partially annular section has a center angle from a range of 240° (inclusive) to 360° (exclusive). The light-guiding elements 87a, 87b are optically separated from one another, in particular by a separating section, in particular by a material of the carrier element 86, so that no radiation is guided from the first into the further light-guiding element 87a, 87b and vice versa.Preferably, the first light-guiding element 87a has a center angle in a range of 89° to 80°, with a separating section having a center angle in a range of 1° to 10°, and the further light-guiding element 87b having a center angle equal to the difference between 360° and the sum of these two center angles. The center angles can be determined for circular arc-shaped center lines of the light-guiding elements 87a, 87b and the separating section.

[0199] Light sources, in particular light sources designed as LEDs, can be arranged on the circuit board 29. The light sources (not shown) can in particular be arranged relative to the light-guiding elements 87a, 87b in such a way that light emitted by the light sources is radiated into the light-guiding elements 87a, 87b. This light is then guided from an irradiation section of the light-guiding elements 87a, 87b to the respective light-emitting section. In this case, the device 1 can comprise at least one light source per light-guiding element 87a, 87b. Preferably, the device 1 comprises at least two light sources per light-guiding element 87a, 87b, each of which can radiate emitted light into the corresponding light-guiding element 87a, 87b. In this case, the number of light sources that radiate light into the first light-guiding element 87a can be greater than the number of light sources that radiate light into the further light-guiding element 87b.A material of the carrier element 86 is particularly opaque and preferably reflective, more preferably fully or highly reflective, for radiation emitted by the light sources. The center line of a cross-sectional area of ​​the light-guiding elements 87a, 87b in a cross-sectional area in which the longitudinal axis L of the device 1 is also arranged can have a curved profile. This enables reliable light guidance from the light sources of the circuit board 29 into the light-emitting element 11. Radiation emerging from the emission section of a light-guiding element 87a, 87b radiates into the light-emitting element 11 (see ). Fig. 1), which is made of translucent material.

[0200] It is further shown that the circuit board 29 is designed in the shape of a hollow disc and has a central through-opening through which the support section 20 of the carrier body and the connecting section of the hollow bodies 15, 19 of the rotating body 7 extend.

[0201] Fig. 14 shows a detailed section through the device 1 for actuating a lock in the area of ​​the circuit board 29. The light emitting element 11 and the push button 9 are shown. On a surface of the circuit board 29 facing away from the door, the Fig. 13 is arranged. An annular force transmission element 87 is arranged in an interior volume of the support element 86. This annular force transmission element 87 has switch actuation webs 88 on an outer surface of the casing, which protrude radially outward from the outer surface of the casing. These switch actuation webs 88 can actuate microswitches 89 arranged on or in the circuit board 29. On a surface of the push button 8 facing the door, the push button 8 has actuation webs 90 that protrude from the surface toward the door. The actuation webs 90 contact a surface of the force transmission element 87 facing away from the door and slide on this surface during a rotational movement of the push button 9.If the push button 9 is actuated and pressed toward the end face 3 of the device 1 facing the door, the actuating webs 90 press on the force transmission element 87, which is then moved with the switch actuating webs 88 toward the end face 3 of the device 1 facing the door. This movement causes the switch actuation webs 88 to actuate the microswitches 89, thus generating a switching signal. This switching signal can be, for example, an input signal from a user, e.g., a signal to perform an actuator-supported locking movement. The force transmission element 87 is spring-mounted on the circuit board 29. When the push button 9 is pressed to actuate the microswitches 89, a spring force must be overcome.If the user releases the push button 9, i.e. if it is no longer pressed, the spring force provided by the spring bearing causes the force transmission element 87 and with it the push button 9 to be moved towards the front side 4 facing away from the door, whereby the switch actuation webs 88 also no longer actuate the microswitches 89.

[0202] Fig. Figure 15 shows a perspective view of a device 1 for actuating a lock in a further embodiment. The device 1 is essentially cylindrical, but a length of the Fig. 15 shown device 1 along a longitudinal axis L of the device 1 is greater than a length of the Fig. 2 is the device 1. The device shown in Fig. The device 1 shown in Figure 15 has a shell surface 2 as well as a front side 3 facing the door and a front side 4 facing away from the door and is - analogous to the explanations for Fig. 1 - with the front side 3 facing the door attached to a door (not shown) or to a locking cylinder of the door.

[0203] According to the Fig. The device 1 shown in Figure 2 also has the Fig. The device 1 shown in Figure 15 has, on the front side 3 facing away from the door, a haptic actuation element designed as a push button 8 and an optical output element 10 with a light output element 11. Likewise, a part of the outer surface 2 of the device 1, which is formed by a rotating body 7, forms a manual actuation element 12 of the device 1.

[0204] In Fig. 15 also shows a locking element 9 of the device 1 for mechanically connecting the support body 6 to the door or a door fastening device. The function of this locking element 9 is described in relation to Fig. 17 explained in more detail. Not in Fig. 15 shows a connection element 46 for connecting an external power source. This was designed with reference to the Fig. The embodiment shown in Figure 1 has also already been explained.

[0205] In Fig. 15 shows an internal volume 14 of the device 1, wherein, among other things, partial bodies of the rotating body 7, in particular a first hollow body 15, are arranged in the internal volume 14. This first hollow body 15 serves to accommodate at least one battery 27 (see Fig. 16) for supplying energy to a drive device of the device 1 and thus forms a battery section or compartment of the device 1. The hollow body 15 has a recess on a front side facing the door, which serves to receive a locking cylinder actuating element, in particular a key. A locking cylinder actuating element, in particular designed as a key, can be arranged in this recess, wherein it is then connected to the hollow body 15 in a rotationally fixed manner, e.g., in a form-fitting manner. Fig. 15 shows that the recess is slot-shaped. Various components or sections of the carrier body 6 are also visible. Fig. 15 a cover element 13 and a carrier fastening element 21, which is provided with a connecting section 18 (see Fig. 16) is mechanically rigidly connected. The support fastening element 21 corresponds to the Fig. 2 shown support fastening element 21.

[0206] Fig. 16 shows a longitudinal section through the Fig. 15 illustrated device 1. Shown are the support fastening element 21, a support body 6 and a rotating body 7 of the device 1. In contrast to the device shown in Fig. In the embodiment of the device 1 shown in Figure 3, the first hollow body 15 of the rotary body 7 is different from that shown in Fig. 3. The first hollow body 15 has a ceiling section 91 and a floor section 33, wherein the ceiling section 91 forms an end face facing the door and the floor section 33 forms a floor side of the first hollow body 15 facing away from the door. It is shown that a casing section 92 of the first hollow body 15 is open at least in sections to enable an arrangement of batteries 27 in the interior volume of the hollow body 15. The batteries 27 can be arranged in the interior volume of the first hollow body 15 such that a longitudinal axis of the batteries 27 can be oriented parallel to the longitudinal axis L of the device 1. The first hollow body 15 has two intermediate walls 93 which extend in the interior volume of the first hollow body 15 between the floor section 33 and the ceiling section 91. A surface of the intermediate walls 93 can be oriented parallel to a longitudinal axis of the first hollow body 15.The intermediate walls 93 are arranged parallel to one another, with the volume between the intermediate walls 93 forming the explained section 38 for receiving a lock cylinder actuating element and a partial volume of the internal volume 17 of the first hollow body 15. Thus, the axis of rotation of the rotating body 7 can also run through the section 38, and the intermediate walls 93 can be arranged at a distance from this axis of rotation. The ceiling section 91 has a slot-shaped opening through which the lock cylinder actuating element can be inserted into the volume between the intermediate walls 93. In . Fig. 16 shows that a bottom surface 94 of the section 38 is offset relative to the bottom section 33 along the longitudinal axis L of the device 1 toward the end face 4 of the device 1 facing away from the door. In particular, a section of the intermediate walls 93 extends through the bottom section 33. The batteries 27 are arranged in a remaining part of the internal volume of the first hollow body. As in the case of the Fig. In the embodiment shown in Figure 3, a connecting section 18 of the support body 6 is arranged between an outer shell wall of the first hollow body 15 and an inner shell wall of a further hollow body 19 of the rotary body 7 and serves for the mechanical connection of a support section 20 of the support body 6 with the door or a door fastening device. The arrangement and design of further elements, e.g. of the device 1, can also be designed according to the embodiment shown in Fig. 3 illustrated embodiment. Fig. 17 shows a perspective view of a door fastening device designed as a fastening plate 5, which is also referred to below as a door fastening element, from a side facing the door. The fastening plate 5 is circular disk-shaped and has a central through-opening 39. The central through-opening 39 is arranged in a central recess 43 in the surface of the fastening plate 5 facing the door, wherein this recess 43 extends from a central region of the fastening plate 5 in the radial direction, starting from a central axis of the fastening plate 5, to the edge of the fastening plate 5. This recess 43 serves to accommodate a section of a locking cylinder protruding from the door. The fastening plate 5 can be plugged onto such a section, wherein the protruding section then extends into the recess 43.

[0207] The central through-opening 39 has a first circular section 39a and a further circular section 39b, wherein a diameter of the first circular section 39a is larger than a diameter of the further circular section 39b. The circular sections 39a, 39b are connected via a connecting section 39c. While a center line of the first circular section 39a can correspond to the longitudinal axis L of the device 1 (when this is fastened to the fastening plate 5), a center line of the further circular section 39b is radially offset from the longitudinal axis L (see Fig. 1) of the device 1. The further circular section 39b serves to accommodate a screw or other fastening means, whereby this screw can be screwed from the side of the mounting plate 5 facing away from the door through the further circular section 39b into any threaded holes present in the locking cylinder or lock or the door. This enables the mounting plate 5 to be screwed to the door.

[0208] A lock cylinder actuating element can extend through the first circular section 39a, which is received in a corresponding receiving section of the rotary body (in Fig. 17 not shown).

[0209] Threaded holes 40 are arranged around the through opening 39, in particular the first circular section 39a. The threaded holes 40 are arranged and / or oriented in such a way that reliable attachment to a predetermined locking cylinder is ensured, e.g., to a locking cylinder used in the EU, Switzerland, the United Kingdom, or the Nordic countries.

[0210] Center lines of two different threaded holes can enclose a predetermined angle, but can also run parallel to each other.

[0211] The threaded holes 40 extend from a side of the fastening plate 5 facing away from the door to the side facing the door. The center lines of the threaded holes 40 from an opening of the threaded hole facing away from the door to an opening facing the door are oriented towards the recess 43. The threaded holes 40 serve to receive screws (not shown), in particular grub screws, which can be screwed into the threaded holes 40 from the side of the fastening plate 5 facing away from the door in order to establish a clamping connection with a locking cylinder arranged in the recess 43. In particular, the Fig. In the embodiment shown in Figure 17, a three-point clamping connection of the fastening plate 5 to the locking cylinder can be established, in particular to the section of the locking cylinder arranged in the recesses 43. The door-facing openings of the threaded bores 40 are arranged in beveled side surfaces of recesses 41 in the door-facing surface of the fastening plate 5, wherein these recesses 41 are open in particular towards the door as well as towards the recess 43. Also shown are two further decentralized through-openings 42, which also serve to accommodate screws, wherein these screws can be screwed from the side of the fastening plate 5 facing away from the door through the decentralized through-openings 42 into any threaded bores present in the locking cylinder or lock or the door. These decentralized through-openings 42 also enable the fastening plate to be screwed to the door.A center line of the decentralized through-openings 42 is arranged radially offset from a center line of the first circular section 39a. Also shown is that the surface of the mounting plate 5 facing the door is, at least in sections, a straight and uncurved surface. This can serve as an adhesive surface 44 for bonding the mounting plate 5 to the door or a lock.

[0212] On a radial outer surface of the casing, the fastening plate 5 has the already Fig. 2 explained guide webs 24 for guiding an assembly movement, which are inserted into corresponding bayonet recesses 45 of the carrier body 6, in particular of a carrier fastening element 21 (see Fig. 2). In the illustrated embodiment, the fastening plate 5 has three guide webs 24 along the outer surface of the casing, which—like the bayonet recesses and in particular corresponding to their arrangement—are arranged irregularly along the outer surface of the casing. The guide webs 24 are arranged on the edge of the outer surface of the fastening plate 5 facing the door and protrude therefrom. In the area of ​​the guide webs 24, the outer surface of the casing has manufacturing-related recesses 100.

[0213] The fastening plate 5 further comprises a spring-loaded locking element 9, which is arranged in a blind hole-like recess in the outer surface of the casing. This locking element 9 is actuated by the spring force of a spring element 47 (see Fig. 19) is pressed outward in a radial direction. When the carrier body 6 is mounted on the fastening plate 5, the locking element 9 can extend through through openings in the carrier fastening element 21 and cover element 13 and thus block a relative movement, in particular a rotational movement for disassembly (dismantling movement) between the carrier body 6 and the fastening plate 5. To release this disassembly movement, a user can press the locking element 9 inward in a radial direction through the through openings and out of them. The disassembly movement is then released.

[0214] Fig. 18 shows a perspective view of the Fig. 17, from a side facing away from the door. On a surface facing away from the door, the fastening plate 5 has stiffening webs 48. Recesses 50 can be arranged between these stiffening webs 48 in order to save material during the manufacture of the fastening plate 5 and to ensure a thickness (strength) of the door fastening device that is as constant as possible for production, since with a thickness that is as constant as possible, undesirably uneven mechanical deformation during a production-related cooling process is minimized. For the sake of clarity, only one stiffening web 48 and one recess 50 are provided with a reference numeral. It is shown that the threaded holes 40 are each arranged in a side wall of one of these recesses.Overall, the door fastening device has the same thickness in the area of ​​the recesses 50 on the surface facing away from the door and in the area of ​​the central recess 43 on the surface facing toward the door, which—as previously explained—enables high-quality manufacturing. Likewise, the fastening plate 5 on the surface facing away from the door has recesses 49 for accommodating screw heads, which can be created, for example, by countersinking, in the area of ​​the further, partially circular section 39b and the decentralized through openings 42.

[0215] Fig. 19 shows a cross section through the Fig. 17 shows the fastening plate 5. In particular, the spring-loaded locking element 9 can be seen. The spring-loaded locking element 9 comprises an enveloping body 70, a push button 71 and the spring element 47. The push button 71 is movably, in particular linearly movable, mounted in the enveloping body 70. An inner surface of a base section 72 of the enveloping body serves as a stop surface for limiting the relative movement between the enveloping body 70 and the push button 71. An inner surface of a cover section 73 of the enveloping body 70 serves as a further stop surface for limiting the relative movement between the enveloping body 70 and the push button 71. A through-opening is arranged in the cover section 73, through which opening a partial section 75 of the push button 71 extends. The push button 71 is of hollow cylindrical design, with the spring element 47 being arranged in an internal volume of the push button 71.A first end of the spring element 47 is supported on the base section 72 of the casing body 70, a second end of the spring element 47 on an inner surface of the end face of the push button 71. A casing section of the push button 71 has partial sections 74, 75 with different diameters, wherein the diameter of a first partial section 74 is greater than the diameter of the further partial section 75. It is also shown that the inner diameter of the casing section is constant. The further partial section 75 extends through the explained through-opening in the cover section 73. The transition between the partial sections 74, 75 forms a stop surface of the push button 71, which can strike the inner surface of the cover section 73. The in . Fig.The enveloping body 70 shown in Figure 19 is essentially cuboid-shaped and is arranged in a recess / depression on the outer surface of the fastening plate 5. This allows a positive connection to be established between the enveloping body 70 and the fastening plate 5. A bottom portion of this depression can have further depressions that serve to insert a tool for disassembling the enveloping body 70.
