Description

[0001] The invention relates to a key-operating device for turning a key in a lock of a door or the like, comprising an actuating element, in particular a locking cylinder, and a housing in which an actuator, a rotating element driven by the actuator for connection with the key, and a gear for mechanical coupling of the actuator with the rotating element are arranged, wherein the housing can be connected via an adapter to a door, a component of the door, such as a door leaf and / or a rosette or the like, and / or the actuating element, in particular the locking cylinder.

[0002] Key-operating devices for turning a key in a lock having a locking cylinder of a door or the like are sufficiently known from the prior art.

[0003] Such a key-operated device is known, for example, from DE 10 2004 021 704 B3. The essential feature there is the design of a coupling device by means of which the actuator, with which the gearbox of the key-operated device is operated, can be engaged and disengaged. The actuator is only coupled to the gearbox when the key is to be turned electrically. Otherwise, the actuator is disengaged, which facilitates manual operation.

[0004] Another key-operated device is known from EP 3 000 953 B1. In this patent, it is specifically provided that the gearbox is arranged on the housing of the key-operated device via an intermediate buffer assembly. The buffer assembly is intended to counteract noise and vibration transmission and thus serves to dampen noise and vibration.

[0005] In the EP 3 000 953 B1, the key-operated device is attached to a lock cylinder via the base body itself, which is described as housing-like. The corresponding opening in the base body is designed for a Euro lock cylinder.

[0006] DE 10 2004 021 704 B3 includes a separate mounting plate. However, this plate is also designed for a specific type of lock cylinder, namely a Euro lock cylinder.

[0007] With key-operating devices known from the prior art, the aim is to achieve a compact and aesthetically pleasing design while simultaneously simplifying the installation and any necessary maintenance for a wide variety of different locking cylinders, including, for example, the maintenance and / or servicing of power sources. A disadvantage of key-operating devices known from the prior art is that they are designed for mounting on only one specific type of locking cylinder. This necessitates the production and stock of different key-operating devices for different locking cylinder types, or at least different mounting plates for different locking cylinder types. This results in high production and logistical costs.Design-related changes to such key operating devices can therefore entail a great deal of effort for adapting all components of the key operating device, especially in the area of ​​connection to a door and / or locking cylinder.

[0008] Based on this state of the art, it is therefore Task the present invention is to further develop the generic key actuation devices in such a way that they are suitable for various types of locking cylinders at low manufacturing costs, are easy to assemble and in particular enable a compact design combined with simplified maintenance and / or repair work.

[0009] To SolutionFor this purpose, a generic key actuation device is provided, in which the adapter is plate-shaped and has a recess, in particular an opening for receiving at least one mechanical connecting element arranged between the rotary element and the actuating element, in particular the locking cylinder, and / or a part of the length of the locking cylinder, and in which the adapter has an area for the arrangement of batteries and / or accumulators as a power source, wherein the batteries and / or accumulators as a power source are arranged in the housing and / or in which the adapter is detachably connected to the housing at least in this area, wherein the adapter closes the housing, in particular on the rear side, at least in this area, preferably completely or partially.

[0010] A key-operated device according to the invention, comprising an adapter, has a recess, in particular an opening in the adapter, which is fundamentally suitable for receiving a locking cylinder that projects lengthwise beyond a surface of a door leaf. The adapter serves to connect the key-operated device to the door leaf or a rosette. A screw connection and / or an adhesive connection can be provided for this purpose. A housing of the key-operated device is connected to the adapter. It is also possible that the recess does not receive a part of the locking cylinder, but merely a mechanical connecting element, which serves to connect a rotary element on one side of the door leaf and the lock in the door leaf.This embodiment of the invention is used, for example, when the locking cylinder, as a connection to a mortise lock, is flush with the door leaf, or at least does not protrude significantly beyond the door leaf.

[0011] The key-operating device according to the invention thus comprises an adapter via which, on the one hand, the housing of the key-operating device can be connected to a door or the like, and on the other hand, to the lock cylinder. According to the invention, this adapter is plate-shaped and has an opening that is prepared, for example, to receive a portion of the length of the lock cylinder. This opening in the adapter for receiving a portion of the length of the lock cylinder can be prepared for the interchangeable reception of modules. The modules are designed, on the one hand, with an outer contour corresponding to the opening in the adapter and, on the other hand, with an opening having an inner contour corresponding to an outer contour of the lock cylinder.

[0012] The adapter's plate-like design facilitates both mounting it to a door leaf or similar surface and mounting the housing or key-operated device to the adapter. Modules can also be easily inserted into such an adapter. A plate-like design is understood to be a version that has a sufficiently large surface area for attaching the adapter to a door leaf, thus providing a flat surface that is preferably positioned across the entire surface of the door leaf, with the opening for receiving the lock cylinder being located within this plate-like area. This design need not be rectangular. Rather, U-shaped, L-shaped, or C-shaped designs, as well as other variations thereof, are also possible and are likewise considered plate-like.

[0013] Such an adapter is inexpensive to manufacture. For example, it can be made of plastic and produced using an injection molding process.

[0014] According to the invention, the adapter has a compartment for batteries and / or accumulators as a power source, which contributes to the compact design of the key-operating device. The power source is located within the housing and is easily accessible by separating the housing from the adapter. This design also has the advantage that batteries can be easily replaced, even by untrained personnel. Nevertheless, the batteries and all other components within the housing are adequately protected against moisture and / or dust.

[0015] The adapter area can be designed such that the batteries and / or accumulators are fully or partially covered, so that the adapter additionally holds the batteries and / or accumulators within the housing via a covering portion of the adapter. The covering portion can be oriented with its surface normal perpendicular or parallel to the surface normal of the door leaf. This limits movement of the batteries and / or accumulators out of the housing towards the adapter and / or relative to the housing's side walls. Preferably, the housing overlaps the adapter, preventing any relative rotation of the housing relative to the adapter due to torque transmitted from the drive to the housing. Alternatively, the housing can be arranged in corresponding recesses or between projections of the adapter.

[0016] Various locking cylinders are known, differing particularly in their external contours. To combine these differently shaped cylinders with the key-operated mechanism, the opening in the adapter is adapted to the largest external contour of the various cylinders. Here, the focus is not on the actual contour, but rather on the maximum dimensions of the cylinders in two perpendicular dimensions (height and width). To adapt the adapter to the external contour of the cylinder to be accommodated, modules are provided that can be inserted into the adapter's opening. These modules have an external contour corresponding to the opening in the adapter and can be positively connected to it. A positive connection represents an alternative or supplementary option.The modules, in turn, have an opening adapted to the outer contour of the lock cylinder to be accommodated. The key-operating device according to the invention is thus universally usable for various lock cylinders, whereby the adaptation to the respective lock cylinder can be achieved via a module that can be manufactured cost-effectively, for example, as an injection-molded plastic product, and the module can be installed in the adapter by non-specialized personnel through a simple insertion and connection process. According to a further embodiment of the invention, the opening in the adapter is prepared for the interchangeable reception of modules, which are designed on the one hand with an outer contour corresponding to the opening and on the other hand with an opening that has an inner contour corresponding to an outer contour of the lock cylinder.

[0017] Advantageously, only one adapter is needed for the various types of lock cylinders. The user of the key-operated device can easily adapt the adapter to the different types of lock cylinders on-site during installation. The user selects the module with an inner contour that matches the outer contour of the installed lock cylinder. This module is then inserted into the adapter's opening, which is designed for interchangeable modules. No tools are required. The adapter can then be mounted around the lock cylinder. Finally, the housing can be attached to the adapter.

[0018] In a preferred embodiment, the modules and adapter have locking elements, in particular locking hooks, in the area of ​​the opening prepared for the interchangeable receipt of modules, and corresponding locking elements, in particular locking openings, on the modules. Locking elements are advantageously suited to enabling quick and easy, in particular tool-free, assembly while simultaneously ensuring a positive-locking connection between the module and the adapter. The design as locking hooks and locking openings is particularly well suited for the detachable insertion of the modules into the adapter. The modules can also be removed from the adapter without damage. In the event of a move or, if necessary,If a change to a different lock cylinder is necessary, the module mounted in the adapter can be replaced with a different module suitable for a different lock cylinder. Therefore, it is not necessary to replace the adapter or even the entire key-operated device.

[0019] Preferably, the opening in the modules is designed to be keyhole-shaped for receiving a Euro cylinder or a Swiss round profile cylinder, oval for receiving a cylinder with an oval cross-section, or circular for receiving a cylinder with a round cross-section. This covers the most common types of cylinders and makes the key-operating device flexible for mounting on these cylinders.

[0020] Another embodiment provides that the module, with its surface oriented towards a door leaf or similar surface, is essentially flush within the adapter. The adapter thus has a flat surface aligned with the door leaf or similar surface. This surface of the adapter therefore rests against the door leaf or similar surface. To ensure the most uniform contact possible between the adapter and the door leaf, the module, when mounted within the adapter, is flush with this surface. This facilitates the mounting of the adapter to a door leaf or similar surface and results in an even distribution of force. This embodiment is particularly suitable for an adhesive bond between the door leaf and the adapter.In the case of a screw connection between the door leaf and the adapter, the flat surface is also advantageous in the area of ​​the module in that the adapter lies flat against the door leaf and no distortion is caused in the adapter by the screw connection.

[0021] It is also possible for the module to have a collar extending towards the surface of the door leaf, serving as a means of engagement with an opening that accommodates the lock cylinder. This design supports the intended positioning of the adapter even if the adapter does not encircle the lock cylinder or only does so for a very short length. The collar need not be completely closed; it can also be formed from sections, lugs, and / or bolt-like projections.

[0022] In another embodiment, the module has two holes for receiving screws, which connect the module to an end face of the lock cylinder. For lock cylinders that already have holes, the adapter can thus be positively connected to the lock cylinder using this module and two screws, without the need for additional drilling, for example, in the door leaf. Furthermore, no other connecting elements are required.

[0023] Alternatively or additionally, the adapter may be provided with holes on both sides of the opening for screws to attach it to a door leaf or rosette. This allows the adapter to be additionally secured to the door leaf with screws, or, if the lock cylinder does not have holes, solely to a door leaf or similar structure. The screws can be used to attach the adapter and the rosette to the door or similar structure.

[0024] Alternatively, for attachment to a door leaf or similar surface, the adapter can also be designed with a surface facing the door leaf or similar surface, which, at least in a partial area leaving the opening for the lock cylinder unobstructed, has an adhesive surface, in particular double-sided adhesive tape or an adhesive layer covered with a removable cover for activation. Attachment with an adhesive surface is particularly suitable, for example, if the user of the key device does not wish to drill into a door leaf or similar surface because, for example, they are a tenant rather than the owner. Furthermore, an adhesive surface is also suitable for doors where drilling is difficult or impossible, such as glass or metal doors. Attachment using an adhesive surface can also be carried out quickly and without tools.

[0025] Another embodiment provides for the adapter to have a U-shaped cross-section, serving as a receptacle for the housing. This allows all necessary components to be housed within the adapter or the key-operating device in a space-saving manner. The U-shaped cross-section of the adapter creates edge elements that are arranged along the outer contour of the adapter and extend parallel to the surface normal of one of the adapter's surfaces. These edge elements serve to receive the housing to be connected to the adapter and can also act as a dustproof and / or moisture-proof element between the adapter and the housing.

[0026] The adapter is preferably adapted to the outer contours of the batteries and / or accumulators. This secures the batteries and / or accumulators in recesses within the adapter when the housing is placed on it. The batteries and / or accumulators are arranged within the housing and supported by the adapter, so that the majority of their volume is contained within the housing, while a portion of their volume is located within the adapter. This allows for a compact housing design in the area of ​​the power source. Simultaneously, all electrical connections are located within the housing, so that only the mechanical connections between the housing and the adapter need to be disconnected when changing the batteries.

[0027] Finally, the adapter can be connected to the housing via snap-fit ​​elements. This allows the housing to be mounted to the adapter without tools. It can also be easily detached from the adapter. This enables, among other things, quick access to components such as the batteries, which can then be replaced effortlessly.

[0028] Further advantages and features will become apparent from the following character description. This will show Fig. 1 the housing of a key-operated device in a first view; Fig. 2 the housing of a key-operated device in three further views; Figs. 3 to 7 views of the key-operated device looking at the internal elements; Fig. 8 a view of a key-operated device looking at a rotary element and a locking cylinder; Fig. 9 the key-operated device and locking cylinder in a cross-section looking at a key; Fig. 10 the rotary element in a top view with a key; Fig. 11 a circuit board with first elements; Fig. 12 the rotary element with receptacles and second elements; Fig. 13 a side view of the rotary element together with the circuit board; Fig. 14 a view of an adapter connecting the housing to the locking cylinder; Fig. 15 a view of the adapter without the housing; Fig. 16 another view of the adapter; Fig.17 Another embodiment of the adapter with an opening for receiving modules and an adhesive device; Figs. 18 and 19 Further views of the adapter; Fig. 20 Modules for the adapter in various versions; Fig. 21 An adapter with a Euro module; Fig. 22 An adapter with a UK module; Fig. 23 An adapter with a Swiss module; Fig. 24 A first view of an adapter with a Scandinavian module and mounted housing; Fig. 25 A second view of the adapter with the Scandinavian module according to Fig. 25.

[0029] Fig. 1 Figure 1 shows a key actuation device 1 according to the invention in a first view. External elements of the key actuation device 1 are visible. In particular, a housing 2 and an adapter 5 for mounting on a lock cylinder (not shown) are visible. Figure 1(shown), a rotary dial 4 and a control surface 3 as part of the housing 2.

[0030] Such a key operating device 1 is usually mounted on the inside of a house or apartment on a locking cylinder 16, for example in a door or the like, wherein the locking cylinder 16 cooperates with a lock (not shown in detail) to operate a latch and / or a bolt of the lock.

[0031] The key operating device 1 encloses a key 17 inserted into the lock cylinder 16 (as will also be shown below). Figs. 9 and 10(as can be seen). The key 17 can be operated, for example, by means of the rotary knob 4 or via an actuator 6 that can be controlled via the operating surface 3. For this purpose, the operating surface 3 has, for example, an activation element 65. The opening and closing of the locking cylinder 16 or the lock using the key 17 located in the key operating device 1 can therefore be carried out mechanically by turning the rotary knob 4 or electromechanically by means of the activation element 65 by controlling the actuator 6.

[0032] Instead of the key 17, an adapter element may also be provided which connects a key-like element inserted into the lock cylinder or a comparable actuating element directly or indirectly to the rotary wheel 4 in a rotationally fixed manner.

[0033] In one embodiment, the activation element 65 is designed in the form of two pushbuttons 66. One pushbutton 66 can be used to open and the other pushbutton 66 to close the lock.

[0034] Fig. 2Figure 1 shows a front view, a side view, and a bottom view of the key-operated device 1. The front view refers to the side that, when mounted on a surface (e.g., a door leaf or a rosette), faces the user. The front view shows that, in this embodiment, the rotary knob 4 has a circular base. It also shows that the housing 2 has a U-shaped base. The side view reveals that the operating surface 3 is not flush with the surface to which the rotary knob 4 is attached, but rather projects beyond this surface, forming a kind of protrusion on the housing 2. As can be seen in the bottom view of the key-operated device 1, the rotary knob 4 extends slightly beyond the protrusion of the operating surface 3 on the housing 2.

[0035] The Figs. 3 to 7Views through the key actuation device 1 show further essential elements of the key actuation device 1 located inside the key actuation device 1.

[0036] In Fig. 3 It can be seen that the externally arranged rotary wheel 4 is non-rotatably connected to and interacts with an internally located rotating element 7. This rotating element 7 is connected via its toothed ring 31 to an output pinion 8 of the actuator 6. The actuator 6 can be, for example, an electric motor, in particular a DC motor. The actuator 6 is in turn connected to a power source 9, for example, batteries or accumulators. The rotating element 7, or rather the toothed ring 31 arranged on the rotating element 7, together with the output pinion 8, forms a gearbox 13 driven by the actuator 6. The actuator 6 is thus permanently mechanically coupled to the rotating element 7 via a gearbox 13.

[0037] The rotating element 7 can be equipped with a device for adjusting the force required to rotate the rotating element 7. This device can, in particular, serve as a child safety lock. The device can include an activation element 65 and an electrical and / or mechanical lock that can be activated or deactivated via the activation element 65. One embodiment provides that the actuator 6 is designed as a DC motor and the electrical lock as a short-circuit brake. The mechanical lock can be designed as a friction brake acting against the rotating element 7. The friction brake is preferably electrically activatable. The adjustment of the force required to rotate the rotating element 7 can be configured to activate and / or deactivate the activation element 65 in a time-dependent and / or actuation-dependent manner. Actuation-dependent activation can be effected by a specific key combination, e.g.,...B. simultaneous pressing of the two buttons 66. The time-dependent activation can be carried out via a specific pressing duration, e.g. pressing one button 66 for 5 seconds.

[0038] The setting of the device can be indicated by a visual signal, for example by an LED.

[0039] Fig. 4 Figure 1 shows a view through the back of the key-operating device 1. "Back" means the side that, in the case of installation, rests against the mounting surface, e.g., a door leaf. Visible are, firstly, guides (10, 11) for receiving fastening elements (43, 44). In one embodiment, these serve to fasten the adapter 5 to the locking cylinder 16. Secondly, the batteries 47 of the power source 9 are visible. The power source 9 can also be electrically connected to the device for adjusting the force required to rotate the rotary element 7.

[0040] Fig. 5shows a view through the front of the key actuation device 1.

[0041] Fig. 6 Figure 1 shows a side view of the key-operating device 1 with a view through to internal elements. The rotary knob 4 is again visible, located outside the housing 2 and non-rotatably connected to the rotating element 7 inside the housing 2 of the key-operating device 1. For this purpose, the rotary knob 4 is connected to the rotating element 7 by means of a shaft-hub connection 12, which extends from the rotary knob 4 into the housing 2 on one side and from the rotating element 7 outside the housing 2 on the other. The key-operating device 1 can be manually operated via the rotary knob 4, which acts like a doorknob, to move a latch and / or bolt of a lock (not shown) in a door.

[0042] In Fig. 7The rotary knob 4 and the rotating element 7 are visible, connected by means of the shaft-hub connection 12. A circuit board 15 is arranged in the housing 2 between the rotary knob 4 and the rotating element 7. The adapter 5 is also visible, which is connected to the housing 2 by means of locking elements 14. A guide 10 for a screw is also visible.

[0043] Fig. 8 Figure 1 shows the key actuation device 1 with rotary wheel 4 and rotary element 7, wherein the key actuation device 1 is mounted on a locking cylinder 16.

[0044] Fig. 9Figure 1 shows the key-operating device 1 and the lock cylinder 16 in a cross-sectional view, with a key 17 inserted in the lock cylinder 16 and held in a receptacle 18 of the rotary element 7. The shaft-hub connection 12 between the rotary wheel 4 and the rotary element 7 is visible, with an additional retaining screw 19 connecting the rotary wheel 4 and the rotary element 7. In the illustrated embodiment, the rotary element 7 is cup-shaped and essentially closed in the direction of the rotary wheel 4. In the direction of the lock cylinder 16, the rotary element 7 is essentially open. An internal circumferential wall 21 provides a space 22. The key 17 is held in this space 22, which forms a key or adapter element receptacle 27. The rotary element 7 also has a projection extending into the space 22.This projection is designed as a circumferential groove 20 in space 22 and serves, on the one hand, to reinforce the rotating element 7 and, on the other hand, allows the key 17 with its key head 23 to rest against this projection or groove 20, so that the key 17 is pushed or held, depending on the key head 23, over the rotating element 7 towards the locking cylinder 16. The key 17 is shown here in a position that is actually undesirable, namely that the receptacle 18, and thus the key 17, is positioned in such a way that the key 17 could theoretically be moved slightly out of the locking cylinder 16 unintentionally, so that rotation of a roller in the locking cylinder 16 would no longer be possible. Therefore, means for determining the position are provided, as well as means to fix the key 17 in a position that can prevent the key from being moved out of the locking cylinder in the aforementioned manner.The means for determining position consist of stationary first elements 33, in particular Hall sensors 34, and second elements 37, in particular magnets 38, which are movable relative to the first elements 33. When the magnets 38 are moved past the Hall sensors 34, signals or impulses are triggered that allow conclusions to be drawn about the position of the magnets 38 and thus about the position of the key 17. If, during position determination, a position is detected at which the key 17 could theoretically be moved slightly out of the locking cylinder 16, an evaluation unit triggers the activation of the inactive actuator 6 or prevents the deactivation of the active actuator 6, so that the actuator 6 rotates the rotary element 7 by an angle sufficient to prevent the key 17 from being moved out of the locking cylinder 16 unintentionally. Reference is also made to the following in this regard: Figs. 11 to 13 referred.

[0045] In this context, "non-active actuator" means a stationary and therefore not energized actuator, while an "active actuator" is energized and thus performs a rotation as intended.

[0046] Further details of the key or adapter element receptacle 27 for the key 17 in the rotary element 7 are taken from the Fig. 10 recognizable.

[0047] Fig. 10Figure 1 shows a detailed view of the rotary element 7 arranged in the housing 2, with the key or adapter element receptacle 27 and the key 17 held therein. Among other things, a circumferential wall 21 of the rotary element 7 is visible. This wall 21 forms an outer surface 32 of the rotary element 7. The rotary element 7 serves to rotate the key 17 to open or close the lock. In the illustrated embodiment, the outer surface 32 corresponds to the surface of a cylinder. In the area of ​​the outer surface 32, the rotary element 7 has a toothed ring 31. This toothed ring 31 is rotationally fixed and integrally connected to the rotary element 7. As described above, the toothed ring 31 meshes with the output pinion 8 of the transmission 13.

[0048] In Fig. 10It can also be seen that the rotating element 7 has two receptacles 18 and 24 for a part of the key 17, in particular the key head 23 or an adapter element. The first receptacle 18 and the second receptacle 24 are formed within the space 22 defined by the circumferential wall 21 and are perpendicular to each other. The receptacles 18 and 24 have a common area 28 centrally located, which is essentially circular. The first receptacle 18 and the second receptacle 24 each have two sub-areas 25 and 26, which are arranged on both sides of the common area 28. Two sub-areas 25, 26 and the common area 28 together form a receptacle 18, 24. The common area 28 divides the first receptacle 18 and the second receptacle 24 into two sub-areas 25 and 26, respectively.Furthermore, the two sub-areas 25 and 26 of the first recording 18 and the second recording 24 extend preferably radially from the common area 28 in the rotating element 7.

[0049] The receptacles 18 and 24 are each defined by two parallel and spaced-apart walls 29. The distance between the walls 29 corresponds essentially to the typical material thickness of the key head 23 or the adapter element, so that the key head 23 or the adapter element is held in the receptacle without play. The walls 29 may exhibit slight elasticity to compensate for different material thicknesses of the key heads 23 or the adapter elements.

[0050] If the common area 28 and the circumferential wall 21 are circular, the common area forms an inner circle interrupted by the sub-areas 25 and 26, and the circumferential wall 21 forms an outer circle. The walls 29 of the first receptacle 18 and the second receptacle 24 preferably terminate flush with a free edge region 30 of the circumferential wall 21 of the rotating element 7. The receptacles 18 and 24 thus extend over the full inner diameter of the circumferential wall 21. A part of the key 17, in particular the key head 23 or the adapter element, engages in the two sub-areas 25 and 26 of the first receptacle 18 or the second receptacle 24.

[0051] The Figs. 11, 12 and 13 show components of a device with which the position, direction of movement and / or speed of movement of the rotary element 7 relative to the housing 2 can be determined.

[0052] For this purpose, two corresponding elements are provided as components, namely that at least one first element 33 is fixedly arranged in the housing 2 and at least one second element 37, which is movable relative to the first element 33, is arranged on the rotating element 7. The corresponding elements 33 and 37 are preferably electromagnetic and / or electromechanical.

[0053] Particularly preferred are the electromagnetic elements Hall sensors 34 and magnets 38, and the electromechanical elements microswitches and triggers. It is therefore possible to provide either a combination of Hall sensors 34 and magnets 38, or a combination of microswitches and triggers, or to provide microswitches and triggers in addition to the combination of Hall sensors 34 and magnets 38. Thus, there is a purely electromagnetic solution, a purely electromechanical solution, and a solution that represents a combination of electromagnetic and electromechanical solutions.

[0054] The arrangement of the Hall sensors 34 and magnets 38, or the microswitches and triggers, is such that the magnets 38 are presented to the Hall sensors 34 when the rotary element 7 rotates, thereby generating a pulse that is detected in an evaluation unit and analyzed with regard to the rotational movement and / or rotational speed. This allows, for example, the determination of whether the rotary element 7 is approaching a stop limiting its rotation. Such a stop can be defined, for example, by the position of the bolt in the lock and / or the end position of the retracted latch. If the rotary element 7 approaches this stop, the current supply to the actuator 6 can be reduced or switched off based on the evaluated pulse to prevent increased power consumption in the stop position. This evaluation is important when the key-operated device 1 is operated upon activation of the actuator 6.

[0055] Generally, such a key-operated device 1 is located on the inside of a building, attached to a door. The key-operated device 1 can be manually turned from inside the building using the rotary element 7 to turn the key 17 in the lock cylinder 16. The key-operated device 1 is not accessible from outside the building, so it can only be operated by activating the actuator 6. For this purpose, a device for entering a key secret can be provided on the outside of the building. This device can be a keypad for entering a specific combination of numbers or letters, which, if it matches the key secret, connects the actuator 6 to the power source 9, causing the actuator 6 to rotate the key 17.Other methods for transmitting the key secret are possible, such as using a transponder, a biometric reader (e.g., a fingerprint or iris scan), or transmitting the key secret stored on a smartphone or similar device. Wireless transmission of the key secret is preferred.

[0056] In the Fig. 11 In the preferred embodiment shown, first elements 33 are arranged on a circuit board 15. The first elements 33 are the Hall sensors 34. The circuit board 15 with the Hall sensors 34 is fixedly installed in the housing 2 and has bores 35 through which screws 40 are guided, with which the circuit board 15 is positively connected to the housing 2 or other fixed components of the key actuation device 1.

[0057] In Fig. 12A preferred embodiment of the second, movable elements 37 and their arrangement in housing 2 is shown. Fig. 12 The depicted rotating element 7 has receptacles 36 distributed around its circumference, arranged at regular angular intervals from one another. The receptacles 36 are thus arranged at regular intervals on a circular path. The receptacles 36 can be fitted with second elements 37. In the example shown, they are fitted with magnets 38. The second elements 37, in this example the magnets 38, are arranged on the circular path at specific angular intervals from one another. The receptacles 36 can be fitted with magnets 38 depending on the desired function of the key-operating device 1.

[0058] Specifically, in the Fig. 12In the example shown, the rotating element 7 has three magnets 38, each arranged on a circular path offset from one another by 120°. First elements 33, i.e., in this example Hall sensors 34, are also visible, arranged on a circuit board 15 fixed within the housing 2 such that their arrangement on a circular path essentially coincides with the circular path on which the receptacles 36 are arranged. The first elements 33, in particular the Hall sensors 34, as well as the second elements 37, are arranged on the circular path at specific angular intervals. In this particular example, four Hall sensors 34 are fixedly arranged on a circular path within the housing 2, each offset from one another by 90°. Other angular intervals and / or numbers of magnets 38 and / or Hall sensors 34 are possible, and the receptacles 36 allow for simplified assembly, at least by the manufacturer.

[0059] It is essential that the number of first elements 33, in particular the Hall sensors 34, is preferably not equal to the number of second elements 37, in particular the magnets 38. With regard to the angular distances, it is essential that the angular distances of the first elements 33 and the second elements 37 do not coincide, so that a complete overlap of all first elements 33 over all second elements 37 is avoided. For this purpose, the angular distances of the first elements 33 can differ from each other, or the angular distances of the second elements 37 can differ from each other, or the angular distances of the first elements 33 can differ from the angular distances of the second elements 37, or both the angular distances of the first elements 33 can differ from each other and / or the angular distances of the second elements 37 can differ from each other as well as the angular distances of the first elements 33 from the angular distances of the second elements 37.The example shown is one in which the angular distances between the first and second elements 37 are not different (the Hall sensors 34 are offset from each other by 90° and the magnets 38 by each other by 120°), but the angular distances between the first elements 33 and the second elements 37 differ due to the arrangement at angular distances of 90° versus 120°. In contrast, it would also be conceivable, for example, to arrange the first magnet 38 at an angular distance of 120° to the second magnet 38 and the second magnet 38 at an angular distance of 60° to the third magnet 38, so that the angular distance between the third magnet 38 and the first magnet 38 would be 180°. This variability allows for the generation of a larger data set, which serves to evaluate the direction of rotation and / or rotational speed or the position of the rotary wheel 4 relative to the housing 2.

[0060] A second embodiment, not shown in the figures, which in particular represents an example of a device for determining the position of the key or adapter element receptacle 27 in an angular position relative to the locking cylinder 16, differs from the example described above in that, in this case, the number of first elements 33, i.e., in particular the Hall sensors 34, is equal to the number of second elements 37, in particular the magnets 38, whereby at least two positions of the key or adapter element receptacle 27 can be detected. Alternatively, triggers can be provided as first elements 33 and microswitches as second elements 37. Preferably, the rotary element 7 has two magnets 38 or microswitches, each arranged on a circular path offset from each other by 180°, and two Hall sensors 34 or triggers are arranged stationary on a circular path in the housing 2, each offset from each other by 180°.

[0061] If the rotary element 7 is in a position where the Hall sensor 34 and magnet 38 or microswitch and trigger are exactly opposite each other, and if the position represents a position of the key 17 relative to the lock cylinder in which the key 17 could, for example, be unintentionally moved slightly out of the lock cylinder 16 by a blow, the elements Hall sensor 34 and magnet 38 or microswitch and trigger generate a signal that initiates activation of the actuator 6 via the evaluation unit, so that the actuator 6 of the rotary element 7 is rotated by an angle sufficient to turn the key 17 in the lock cylinder 16 to such an extent that a relative movement of the key 17 in the longitudinal axis direction of the lock cylinder 16 is excluded.

[0062] Fig. 13Figure 1 shows a side view of the circuit board 15, the rotary element 7, and the lock cylinder 16. Here it is particularly clear that the first elements 33, in the form of Hall sensors 34, are fixedly mounted on the circuit board 15. The second elements 37, which are movable relative to the first elements, are the magnets 38. These magnets 38 are mounted on a gear 39 of the rotary element 7. The gear 39 engages with the drive pinion 8. When the rotary element 7 is set into rotation, either by the actuator 6 driving the gearbox 13 or by manually turning the rotary knob 4, the movable elements 37 are moved past the fixed elements 33, triggering a pulse.In the embodiment with the Hall sensors 34 and the magnets 38, an electromagnetic pulse is triggered, but depending on the embodiment, an electromechanical pulse or both an electromechanical and an electromagnetic pulse can also be triggered.

[0063] The operating principle of determining position, direction of movement, or speed of movement using Hall sensors and magnets is based on the fact that Hall sensors, when subjected to a magnetic field perpendicular to their semiconductor layer, produce an output voltage. This output voltage is also called the Hall voltage. Hall sensors typically have four electrodes for this purpose. Of these four electrodes, two are used to supply a current, and two, located orthogonally to the first two, serve as measuring electrodes. The function of the electrodes can be interchanged. This corresponds to a spinning-current operation. The measuring electrodes measure the Hall voltage. Thus, the moment a magnet approaches a Hall sensor, the Hall voltage increases; conversely, when the magnet moves away, the Hall voltage decreases. This increase or decrease is measured by the sensor's position and direction of movement.The voltage drop corresponds to the electromagnetic pulse triggered when a magnet passes by a Hall sensor. Hall sensors can be designed as discrete Hall sensors or as integrated Hall sensors. Unlike discrete Hall sensors, integrated Hall sensors are incorporated into circuits, which may include signal amplification, analog-to-digital conversion, or digital signal processing. Possible shapes include rectangular, butterfly, or cross-shaped.

[0064] According to the exemplary embodiment, the position, direction of movement, and / or speed of movement of the rotating element 7 relative to the housing 2 are determined by arranging a Hall sensor 34 in a fixed position within the housing 2 and moving a magnet 38, movable relative to the Hall sensor 34, past the Hall sensor on the rotating element 7, thereby triggering an electromagnetic pulse. This pulse is then evaluated with respect to the position, direction of movement, and / or speed of movement of the rotating element 7 relative to the housing 2. Beyond position determination, the direction of movement and / or speed of movement of the rotating element 7 can thus be determined continuously or dynamically throughout its rotation. This is particularly simplified when the number of Hall sensors 34 is not equal to the number of magnets 38, or when the angular distances on one or more of the circular paths differ.

[0065] In the exemplary embodiment of a device for determining the position of the key or adapter element receptacle 27 in an angular position relative to the locking cylinder 16, the position is determined by a first element 33 being fixedly arranged in the housing 2 and a second element 37, movable relative to the first element 33 and arranged directly or indirectly at the key or adapter element receptacle 27, being moved past the first element 33 and triggering an electromechanical and / or electromagnetic pulse which is evaluated with regard to the position of the key or adapter element receptacle 27 relative to the housing 2, whereby a static comparison of the two elements 33 and 37 is detected as a pulse which represents a specific position of the key or adapter element receptacle 27 in an angular position relative to the locking cylinder 16, and generates a signal to activate the actuator 6.so that actuator 6 is moved through a certain angle until elements 33 and 37 are no longer statically opposed to each other and therefore no longer generate any momentum.

[0066] As an adapter element for insertion into the key or adapter element receptacle 27, devices that can be connected to the key or adapter element receptacle 27 in a form-fit or force-fit manner are suitable, such as adapter elements with an end-mounted polygonal head that can be inserted into the key or adapter element receptacle 27.

[0067] Using the described means and methods for determining the position, it is possible to ascertain whether the rotating element 7, and thus the key 17, is in a position that allows the key 17 to be moved out. Typically, positions in which the key 17 can be moved out of the lock cylinder 16 are those in which the key 17 is inserted vertically or horizontally (depending on the design of the lock cylinder and the key) in the lock cylinder 16. Positions in which the key 17 can be moved back and forth are undesirable, as this is equivalent to the key 17 being unintentionally moved a portion of the lock cylinder 16. With the key 17 even slightly moved out of the lock cylinder 16, proper operation could then be prevented, since the rotational movement would be blocked by at least one pin inside the lock cylinder 16 that is not in a release position.If a position is determined that allows the key 17 to be moved out of the lock cylinder, the rotary element 7 is rotated out of this position by the actuator 6. The position can be determined continuously or dynamically during actuation of the key-operating device 1, i.e., throughout the entire rotational movement, or statically, i.e., only after the rotational movement, e.g., an opening or closing operation, has ended. Determining the direction of movement can serve to identify an opening or closing operation. The speed of movement can be determined and adjusted.

[0068] Fig. 14 Figure 1 shows an embodiment of the adapter 5 by means of which the housing 2 can be connected to a door or the like and / or the locking cylinder 16. The adapter 5 is plate-shaped, as is also the case in particular with the Figs. 15 and 16can be removed, and has an opening 41 for at least partial reception of part of the length of a lock cylinder 16.

[0069] In Fig. 14It can also be seen that the lock cylinder 16 is partially received by the adapter 5. The lock cylinder 16 thus protrudes, for example, a few millimeters from the door leaf or the escutcheon. The adapter 5, with its corresponding opening 41, is placed onto this part of the lock cylinder 16, so that the lock cylinder 16 is positively engaged in the opening 41. For a force-fit connection between the adapter 5 and the lock cylinder 16, fastening is provided by means of fasteners in the form of a screw 43 and two spring-loaded bolts 44. Guides 10, 11 are provided in the adapter 5 to receive the screw 43 and the bolts 44; these guides are oriented towards the outer surface 48 of the lock cylinder 16. In the case of installation, the fasteners 43, 44 are therefore in contact with the outer surface 48 or the outer surface of the lock cylinder 16.The adapter 5 can be adjusted and fixed relative to the lock cylinder 16 using the screw 43 and the bolts 44. Additionally, the adapter 5 can be bonded to the door leaf.

[0070] As can be seen from a synthesis of the Figs. 15 to 17 As can be seen, the opening 41 for receiving the locking cylinder 16 has a circular area 46 around which three guides 10, 11 are arranged. The three guides 10, 11 can be seen in particular as Fig. 15A guide 10 for receiving a screw 43 is designed to extend radially to the circular area 46 of the opening 41, according to the embodiment. The two guides 11 for receiving the spring-loaded bolts 44 are preferably oriented secantally. It is particularly preferred that the secantly oriented guides 11 are arranged at equal angular distances to the radially oriented guide 10 and that the angular distance between the secantly oriented guides 11 is smaller than the angular distance between the radially oriented guide 10 and each secantly oriented guide 11. Thus, according to the embodiment, the angle between the radially oriented guide 10 and each of the two secantly oriented guides 11 is larger than the angle between the two secantly oriented guides 11. The angular distance between the radial guide 10 and each of the two secantly oriented guides 11 therefore corresponds, for example, toat an obtuse angle and the angular distance between the two secantial guides 11 is an acute angle. In the illustrated embodiment, the angular distances between the radially oriented guide 10 and each secantly oriented guide 11 are identical.

[0071] In Figs. 15 and 16 The locking elements 14, with which the adapter 5 can be connected to the housing 2, can also be seen.

[0072] As this is particularly evident from Fig. 15 As can be seen, the adapter 5 also has a compartment 45 for the arrangement or installation of the power source 9. Batteries 47 and / or accumulators can be accommodated in this compartment 45. The compartment 45 can be adapted to the external contours of commercially available batteries 47 or accumulators. By separating the housing 2 from the adapter 5, which is fixed to the lock cylinder 16 and, if applicable, to the door leaf, the batteries 47 become accessible for replacement.

[0073] The Fig. 16 It can also be seen that the adapter 5, which serves as a receptacle for the housing 2, has a U-shaped cross-section and, on both sides of the opening 41 for receiving the locking cylinder 16, has holes 49 for receiving screws to fasten the adapter 5 to a door leaf or the like. In particular, two holes 49 can be provided on each side of the opening 41. The distance between the holes 49 on both sides of the opening 41 can, for example, correspond to the distance that commercially available door rosettes have as the hole spacing.

[0074] The Figs. 17 to 19 Figure 1 shows another embodiment of an adapter 5. This adapter 5 is also plate-shaped and U-shaped in cross-section and has an opening 50 for partially accommodating part of the length of the locking cylinder 16. Modules 55, such as those found in [reference to specific product / service], can be inserted into this opening 50. Fig. 20The adapter 5 is prepared for the interchangeable reception of such modules 55. The modules 55 are designed such that they have, on the one hand, an outer contour corresponding to the opening 50 in the adapter 5 and, on the other hand, an opening 50 with an inner contour 56 corresponding to the outer contour of a locking cylinder 16, whereby the modules 55 enable the adapter 5 to be adapted to different locking cylinders 16. As can be seen from the Figs. 17 to 20 As can be seen, the opening 50 in the adapter 5 and thus also the modules 55 are oval in the embodiment shown.

[0075] In Fig. 20Four modules 55 are shown as examples, which can be inserted alternatively into the opening 50 in the adapter 5. The openings 50 in the modules 55 are preferably keyhole-shaped for receiving a Euro cylinder or a Swiss round profile cylinder, oval for receiving a cylinder with an oval cross-section, or circular for receiving a cylinder with a round cross-section. Depending on their inner contour 56, the modules 55 shown are thus suitable, for example, for a Euro cylinder 59, a UK oval cylinder 61, a Swiss round profile cylinder 62, or a Scandinavian oval cylinder 63. The oval cross-section of the modules 55 has the advantage that all modules can be inserted alternatively into the opening 50 of the adapter 5, so that the adapter 5 can be combined with common outer contours of the cylinders 16 in the modules 55.Furthermore, additional contours that deviate from the standard outer contours can be produced if required.

[0076] The modules 55 are to be interchangeable, i.e., replaceable at will, and inserted into the opening 50 of the adapter 5. The modules 55 therefore have locking elements, in particular locking hooks 54, and the adapter 5 has corresponding locking elements, in particular locking openings 53, in the area of ​​the opening 50 corresponding to the locking elements on the modules 55. How the Fig. 20 As can be seen from the diagram, the modules 55 preferably have locking elements in the form of locking hooks 54, which, according to the exemplary embodiment, are formed on both sides of the outer edge of the module 55. The locking openings 53 are, as shown in the diagram, Figs. 18 and 19The locking elements are preferably slot-shaped. In the assembled state, the locking hooks 54 engage in the locking openings 53. The modules 55 are thus clipped into the adapter 5. The locking elements 53, 54 therefore serve to provide a force-fit, yet detachable connection between a module 55 and an adapter 5.

[0077] In addition to the locking elements 53, 54, stop elements 57 and stop surfaces 52 can also be provided, as can be seen from the Figs. 18 to 20 can be removed. In the assembled state, the stop elements 57 of a module 55 are in operative connection with the stop surfaces 52 of an adapter 5. They form a positive-locking connection between module 55 and adapter 5. They thus contribute to the connection between module 55 and adapter 5 being secured against slippage.

[0078] The Figs. 17 and 18Figure 1 shows a view of the adapter 5, in which the surface 60 of the adapter 5 is visible, which, in the fully assembled state, rests against a door leaf or the like. This surface 60 of the adapter faces a user of the key-operated device 1 when the user inserts a module 55 into the adapter 5. To insert the module, the user can, for example, grasp the module 55 with two fingers, gently squeeze the locking hooks 54 together, insert the locking hooks 54 into the locking openings 53, and allow them to engage by releasing the pressure. In the assembled state, the module 55 is preferably arranged flush within the adapter 5 with the surface 60 of the adapter 5 facing the door leaf or the like.

[0079] The surface 60, which is aligned with a door leaf or the like, can have an adhesive device 51 at least in a partial area, leaving the opening 50 free for the locking cylinder 16, as shown in Fig. 17The adhesive device 51 also has an opening, specifically in the area where the adapter 5 has an opening 50 for the locking cylinder 16. The adhesive device 51 can preferably be a double-sided adhesive tape or an adhesive layer covered with a removable cover for activation. The adapter 5 can thus be attached to the door leaf or the like by means of the adhesive device 51.

[0080] Alternatively or additionally, the adapter 5 can be attached to a door leaf with screws. For this purpose, the adapter 5 preferably has holes 49 on both sides of the opening 50 for receiving screws.

[0081] Another embodiment provides that the module 55 has two bores 58 for receiving screws, which screws connect the module 55 to an end face 64 of the lock cylinder 16. The bores 58 are in Fig. 20 and Fig. 26as can be seen. The adapter 5 accordingly has two bores in the area of ​​the opening 50 for receiving modules 55.

[0082] Fig. 21 Figure 5 shows an adapter 5 with a module 55 for a Euro cylinder 59 and a Euro cylinder 59, part of the length of which is accommodated in the adapter 5. The adapter 5 is thus connected to the Euro cylinder 59 via the module 55, which has an inner contour 56 that corresponds to the outer contour of the Euro cylinder 59.

[0083] Similarly, it shows Fig. 22 an adapter 5 with a module 55 for a UK oval cylinder lock 61 and a UK oval cylinder lock 61 and Fig. 23 an adapter with a module 55 for a Swiss round profile and a Swiss round profile locking cylinder 62.

[0084] In Fig. 24An adapter 5 with a module 55 for a Scandinavian oval cylinder lock 63 is shown. In this figure, the housing 2 is attached to the adapter 5 by means of the snap-fit ​​elements 14 for housing attachment. The curvature of the U-shaped adapter 5 points in the opposite direction to that shown in the previous figures. This is due to the bores in the Scandinavian oval cylinder lock 63. When the cylinder lock 63 is installed in a door, these bores are located above the keyhole 17. However, since the adapter 5 is to be constructed identically for all module types 55, the bores 58 for the Scandinavian oval cylinder lock 63 in the adapter 5 must be located between the area for the power source 9 and the circular area 46.For mounting on the Scandinavian oval cylinder lock 63, the adapter 5, and thus the key operating device 1, must be rotated 180° compared to mounting on the other cylinder locks shown. Therefore, when mounting on a door or the like, the rotary knob 4 points downwards in the case of a Scandinavian oval cylinder lock 63 (see also...). Fig. 25 ), but upwards for the other lock cylinder types shown.

[0085] The invention is described in particular in connection with known locking cylinders 16 and the keys 17 used with them. Such a locking cylinder 16 need not be formed in one piece. Rather, locking elements formed in two pieces can also be provided, which on the one hand have a lever for actuating a lock, in particular for moving a latch and / or a bolt, and on the other hand have a connecting element between the two parts of the locking element. Such a locking element, which can again also be formed in one piece, is to be referred to as an actuating element within the meaning of the invention and must have an element that is rotatable relatively within the lock, which can drive the mechanism of the lock via the lever. The invention can, for example, also be used after removing part of such a locking element by connecting the remaining part of the locking element to the connecting element.An adapter element may be provided for this purpose.
