Electromechanical mounting device for insertion into a cylinder-type locking device

Description

[0001] The invention relates to an electromechanical installation device for insertion into a cylinder-type locking device or into a switching element according to claim 1. Furthermore, the invention relates to a cylinder-type locking device equipped with such an installation device. Finally, the invention relates to a locking device system with several locking devices, each comprising an installation device. State of the art

[0002] EP 1 914 368 B1 discloses a locking cylinder as a locking device with a locking element which, in a first position, is located in both a rotor and a cylinder housing, thus blocking rotation of the rotor relative to the cylinder housing. In this position, the locking element engages in a recess of the cylinder housing. In a second position, however, the locking element is completely located in the rotor, so that the rotor can rotate relative to the cylinder housing. A disadvantage of this is that the cylinder housing must have a recess for the locking element. Therefore, each different cylinder housing must have its own recess.

[0003] Document CH 717 289 A2 discloses a lock cylinder with a mechanical mounting device for insertion into a lock cylinder housing. The lock cylinder includes an electric motor which, when activated, acts on a locking bolt.

[0004] It is therefore an object of the present invention to further develop components for a locking device, a locking device and a locking device system in such a way that it is easier and / or more flexible to manufacture. Disclosure of the invention

[0005] The problem is solved by independent claim 1. Advantageous embodiments of the device are specified in the dependent device claims, the description, and the figures. Furthermore, the problem is also solved by a locking device according to claim 15. Advantageous embodiments of the locking device are specified in the associated dependent device claim, the description, and the figures. Additionally, the problem is also solved by a locking device system according to claim 17. Advantageous embodiments of the locking device system are specified in the description and the figures. Features and details described in connection with the installation device according to the invention also apply, conversely, to the locking device and / or the locking device system according to the invention.The features mentioned in the description and in the claims can each be essential to the invention individually or in combination.

[0006] According to the invention, an electromechanical installation device for insertion into a cylinder-type locking device or into a switching element is provided, comprising a stator and a rotor as components. The stator serves for insertion into a locking device housing or a switching element housing. Furthermore, the installation device is provided with a locking element. The rotor is mounted in the stator, in particular rotatably. The locking element is mounted in one of the components, in particular linearly movable, and is movable between a first position and a second position. In the first position, the locking element prevents rotation of the rotor in the stator. In the second position, the locking element allows rotation of the rotor in the stator.

[0007] In the first position, the locking element preferably engages in a locking element recess of the other component. This allows the locking element to preferably connect the rotor and the stator. Because the locking element is at least partially located in the stator in the first position, and the stator is designed to be inserted into a locking device housing, it is not necessary to provide a recess or bearing for the locking element in the locking device housing. Instead, the stator, which is inserted into a locking device housing, is a separate component that interacts with the locking element and thus prevents rotation of the rotor.

[0008] The first component can correspond to either the rotor or the stator. Similarly, the second component corresponds to the other of the two, i.e., either the stator or the rotor. Thus, the locking element can either be mounted in the rotor and engage with the stator in the first position, or the locking element can be mounted in the stator and engage with the rotor in the first position.

[0009] Preferably, the locking element is mounted in the rotor. The stator preferably includes a locking element recess into which the locking element engages in the first position. That is, the locking element is housed in the rotor, which has the advantage that the stator can be made relatively thin. In the second position, the locking element is preferably disengaged from the locking element recess.

[0010] Preferably, the locking element projects into the locking element recess in the first position. However, preferably, the locking element does not project beyond the outer circumference of the stator in the first position. The locking element is preferably arranged in a space bounded by the outer circumference of the stator in the first position. Thus, the locking device or switching element housing can be designed without a recess for the locking element.

[0011] It can be provided that the locking element is tensioned in the first position by at least one spring in the direction of the first position. The locking element preferably moves from the first position to the second position in one direction of movement. Preferably, the installation device, in particular the stator, comprises an interface against which the locking element rests in the first position and which limits the movement of the locking element against the direction of movement, i.e., when moving into the first position.

[0012] The locking device with the mounting device is preferably used to lock a spatial area. This spatial area is particularly fixed. For example, it could be a room in a building, such as an office, apartment, or house, or a storage space, such as a cupboard, mailbox, chest, box, safe, or drawer. The locking device is specifically designed to be installed in or attached to a locking element, particularly a door-like element, such as a front door, apartment door, room door, cupboard door, mailbox flap, or the front of a drawer.

[0013] Preferably, the stator of the installation device is at least indirectly connected to the locking element in a rotationally fixed manner. The locking device housing is preferably connected to the locking element in a rotationally fixed manner.

[0014] The locking device may have a driver or be connectable to one. A rotation of the rotor of the installation device serves to rotate the driver.

[0015] The driver is preferably designed as an eccentric. The driver can be designed as a locking lug. A rotation of the driver in a first direction may serve to move the locking element from an unlocked state to a locked state. A rotation of the driver in a second direction may serve to move the locking element from a locked to an unlocked state. For example, the installation device can be inserted, at least indirectly, into a mortise lock. In this case, a rotation of the driver can cause movement of the bolt of the mortise lock. Thus, a rotation of the driver in a first direction can, for example, cause the bolt to extend and thereby bring the locking element into the locked state. A rotation of the driver in a second direction can, for example,to cause the bolt to retract and thus bring about the unlocked state of the locking element.

[0016] Alternatively, the drive pin itself can act as a latch. For example, rotating the drive pin in one direction can cause it to assume a locking position. Rotating it in a second direction can cause it to assume an unlocking position.

[0017] According to the invention, the locking device housing is designed for insertion into or attachment to the locking element. The locking device is designed as a locking cylinder, in particular as a double cylinder or half cylinder, as a knob cylinder, as a furniture cylinder, or as a padlock.

[0018] Alternatively, the installation device can be designed for a switching element. This ensures that the switching element can only be operated by authorized users. A actuator of the switching element can be used to actuate a switch or push button. Therefore, the installation device can be integrated into a switching element, particularly a key switch, or it can function as a key switch.

[0019] The installation device, in particular the rotor, can be connected or connectable to a knob or a key in order to transmit a mechanical torque to the rotor. If interaction with a key is intended, the installation device, in particular the rotor, can include a keyway.

[0020] Preferably, the installation device includes a connecting section for connection to a driver.

[0021] The electromechanical installation device comprises an electromechanical actuator. The actuator can, in particular, be designed as an electric motor.

[0022] The actuator serves to enable the driver to move when the rotor rotates.

[0023] The actuator serves to enable the locking element to be moved into the second position.

[0024] The installation device may include an electronic control device, in particular a processor and / or a controller, to control the actuator. The control device may include an electronic memory.

[0025] The installation device may include a transmission device. The transmission device may be configured as a transmitter and receiver, a biometric sensor, a keypad for PIN entry, and / or a contact element for electrically contacting a key, particularly an electronic key. The transmitter and receiver may be configured to communicate with a mobile device, in particular a mobile phone or a card, via short-range wireless communication, in particular RFID or Bluetooth Low Energy.

[0026] The transmission device can be used to send and / or receive electronic data that allows a user's authorization to unlock the spatial area to be determined. For example, the transmission device can receive an authorization code and / or an authorization time window, which is checked by the control device. If the check is successful, the actuator can be activated to enable rotation of the drive mechanism.

[0027] Alternatively, the transmission device can transmit an opening command. Based on this opening command, the actuator can be controlled to allow the driver to rotate. For example, the opening command can electromechanically move the locking element into the second position or electromechanically release the movement into the second position.

[0028] The transmission device serves, in particular, additionally or alternatively, to transmit electrical energy to the installation device. The electrical energy can be used to actuate the actuator and / or the control device.

[0029] Preferably, the installation device according to the invention comprises a locking element. The locking element can be moved by the actuator into a release position. An actuator assembly of the installation device comprises the locking element, the actuator, and the locking element.

[0030] Preferably, the blocking element in a release position allows the movement of the locking element from the first position to the second position, and in a blocking position prevents the movement of the locking element from the first position to the second position.

[0031] In particular, it can be provided that, when the locking element is in the release position, the rotation of the rotor allows the locking element to move into the second position. In this process, the stator, in particular, forces the locking element into the second position.

[0032] Preferably, the blocking element includes a recess into which the locking element is arranged in the second position. In the first position, the locking element is located outside the recess. In the release position, the blocking element is arranged such that the recess is opposite the locking element, allowing the locking element to retract into the recess.

[0033] The actuator is primarily used to enable movement of the locking element from the locking position to the release position. Thus, the actuator can move the locking element to the release position and / or, for example, initiate movement of the locking element to the release position by tensioning a spring.

[0034] The blocking element can, for example, be disc-shaped.

[0035] The blocking element can be movable, in particular rotatable, between the release position and the blocking position.

[0036] The locking element can be arranged on the output shaft of the actuator, which is designed as an electric motor. Preferably, the actuator allows the locking element to rotate from the locking position to the release position. This allows for a very space-saving design.

[0037] According to the invention, the rotor houses the electromechanical actuator and / or preferably the blocking element.

[0038] In the mounting device, the stator can be cylindrical. This is advantageous for installation in a locking device housing. Preferably, the stator can include at least one opening designed to receive a fastening element passing through the locking device housing for rotationally fixed attachment of the stator to the locking device housing. This is a very simple method of securing the stator.

[0039] The stator can include multiple openings to accommodate a fastening element when used in different locking device housings. This increases the application flexibility of the mounting device.

[0040] The rotor may include a connecting section which, in the installed state, is designed to be directed towards a driver of the locking device.

[0041] The rotor can be designed to engage with a coupling element. The coupling element can be designed to engage with the driver. This creates the operative connection between the installation device, in particular the rotor of the installation device, and the driver. The locking device can include the coupling element.

[0042] Preferably, the connecting section includes a guide for the coupling part.

[0043] The connecting section preferably extends beyond the stator.

[0044] Preferably, the stator comprises a stator body and a casing. The casing preferably encloses the stator body at least partially.

[0045] It may be provided that at least one opening is formed in the stator body and in the casing.

[0046] The stator can include a stator insert element. The stator insert element preferably includes at least part of the aforementioned locking element recess.

[0047] Preferably, the stator insert element is inserted into the stator body. It is possible that the stator insert element is covered externally by the casing. This facilitates easy assembly.

[0048] In particular, the locking element recess can include a contact surface. The contact surface and the locking element are preferably configured such that the locking element is spaced apart from the blocking element by its contact with the contact surface. This spacer enables virtually wear-free and damage-free operation of the locking element over time. Additionally or alternatively, it can be provided that the locking element remains in its first position due to its contact with the contact surface.

[0049] It may be provided that the stator insert element encompasses the contact surface.

[0050] The stator may include a stator element that has an additional contact surface for the locking element in order to move the locking element from the first position to the second position.

[0051] Preferably, the stator element is movably mounted within the rest of the stator.

[0052] The stator comprises, in particular, an annular projection that is received in the rotor and / or projects into the keyway. The projection is interrupted by a gap in at least one section to interact with a key in a bayonet-like manner as a key removal lock. The annular projection is preferably divided into at least a first protective element part and a second protective element part. The first and second protective element parts are preferably separate from each other. Preferably, the first and second protective element parts are pressed against each other by a spring device.

[0053] The spring assembly is designed in particular as a leaf spring, which is adapted to the contour of the protective element parts. The leaf spring sits advantageously on the outer surface of the first and second protective element parts and presses them together, so that the spring assembly has a clamp-like design.

[0054] The spring device essentially compresses the gap to a smaller size. Its leaf spring design makes it particularly space-saving. For example, the spring device can be curved, especially in the shape of an open ring.

[0055] The spring mechanism allows the protective element components to be clamped to the rotor, resulting in easy assembly.

[0056] According to the invention, the installation device comprises an extension element. The extension element is designed to move axially to a rotor axis in a first direction when a key is inserted, and to move axially to a second direction opposite to the first direction when the key is removed. This allows the installation device to perform certain actions simply by inserting the key. Thus, the extension element extends the effective range of the key. The key channel can therefore be designed to be particularly short.

[0057] The extension element is movable in an axial direction, particularly linearly, between an insertion position and a withdrawal position.

[0058] If the extension element moves linearly, it can alternatively be called a slider.

[0059] The extension element is preferably moved from the pull-out position to the insertion position when a key is inserted and / or moved from the insertion position to the pull-out position when a key is removed.

[0060] Because this function is performed by the extension element as part of the locking mechanism, it is possible to better protect the interior of the locking mechanism against tampering. The locking mechanism can include at least one wall behind which the extension element is at least partially located. "Behind" here refers to the perspective of the user operating the locking mechanism. The insertion position is a position in which the extension element is further away from the user than in the removal position. In this position, the wall can define a keyway to the rear.

[0061] The extension element preferably travels its essential length along the rotor axis of the closing device and is mounted in a manner axially movable with respect to the rotor axis.

[0062] The extension element is located inside the locking device where the locking mechanism is situated. Thus, the control device, actuator, blocking element, and / or locking element are protected from tampering, particularly by the wall.

[0063] Preferably, each insertion movement of a key into an end position acts on the extension element. In particular, each insertion movement of the key into an end position acts on the extension element in such a way that the extension element is moved from the withdrawal position to the insertion position.

[0064] The locking device may include a force storage device, in particular a spring, to force the extension element into the release position. Preferably, the extension element includes an engagement element for engaging the key. This ensures that the extension element is always moved from the insertion position to the release position when the key is removed.

[0065] The extension element is preferably designed to allow the coupling part to be moved.

[0066] The extension element is specifically designed to be movable independently of the coupling part. "Independent" in this context means that the movement of the extension element cannot be transmitted to the coupling part via a connection. However, the independent movement of the extension element from the coupling part does not preclude the coupling part from following the movement of the extension element, for example, because the coupling part is spring-loaded in the direction of the extension element.

[0067] In particular, the extension element is designed in the axial direction without a positive fit to the coupling part.

[0068] The coupling part is preferably arranged outside the stator, in particular in the guide of the rotor.

[0069] It can be provided that the coupling part remains in a engaged position when the extension element moves in the second direction. In the engaged position, the coupling part is operatively connected to the drive. In a disengaged position, the coupling part is disengaged from the drive. Because the coupling part remains in the engaged position when the extension element moves into the release position, an operative connection between the rotor and the drive remains after the key is removed. Furthermore, because the locking element prevents movement of the rotor after the key is removed, the locking element simultaneously prevents movement of the drive. This protects the drive from tampering. The coupling part can include a coupling element. The coupling element can establish the operative connection between the rotor and the drive.The coupling element can be guided, in particular, within the rotor guide. Preferably, the coupling element remains in the engaged position, i.e., in operative connection with the drive element, when the extension element moves into the release position. Thus, the coupling element ensures that the engaged position is maintained. Preferably, the extension element is movable independently of the coupling element.

[0070] Preferably, the installation device comprises a front panel that faces outwards when installed. In the assembled state, the locking element is positioned between the front panel and the coupling part. Furthermore, the locking element is positioned between the front panel and the guide for the coupling part.

[0071] It may be provided that the actuator, in the assembled state of the mounting device, is positioned between the front and the guide for the coupling part.

[0072] Preferably, it is provided that each insertion movement of the key into an end position acts on the extension element.

[0073] It may be designed that the extension element acts on the coupling part without an intermediate energy storage device. While an energy storage device, in particular a spring, may be provided to push the extension element in the second direction, the energy storage device does not serve to charge itself if the extension element and the coupling part have different movement capabilities, for example, if the coupling part cannot engage with the drive element due to a momentary spatial arrangement.

[0074] The coupling element is preferably designed as a multi-part assembly with a spring. The spring allows mechanical energy to be stored when the coupling element is momentarily arranged in a spatial configuration relative to the drive element that prevents engagement. If the spatial configuration of the coupling element relative to the drive element allows engagement, the coupling element engages by means of the spring force of its own spring.

[0075] Preferably, it is provided that torque can be transmitted from the rotor to the coupling part without the extension element transmitting the torque. This makes it possible to design the extension element in a more delicate manner and save installation space.

[0076] The extension element can be designed to interact with the coupling part without a positive locking connection in the direction of rotation. This prevents the extension element from transmitting torque to the coupling part.

[0077] The extension element can be designed to interact with the coupling part without a positive fit.

[0078] The extension element is preferably formed in one piece.

[0079] The extension element is preferably angled. It can be provided that a first part of the extension element, intended for interaction with the key, extends radially further outwards than a second part of the extension element, intended for interaction with the coupling part. The advantage is that the second part is positioned more centrally, allowing the coupling part to be pushed more easily. This keeps the dimensions, particularly of the coupling part, to a minimum.

[0080] Preferably, the stator comprises a base side which, in the installed state, is configured to face inwards and / or towards the aforementioned driver of the locking device. The base side is preferably configured to face away from a keyway or knob and / or from the front.

[0081] The rotor preferably includes a projection that abuts the base. In particular, the projection is formed integrally with a connecting section. Additionally or alternatively, the projection can be formed integrally with a guide for the locking element. Additionally or alternatively, the projection can be formed integrally with an installation space for the locking element, the actuator, and / or the control device. Additionally or alternatively, the projection can be formed integrally with an installation space for the actuator assembly.

[0082] The rotor can be subdivided into a first section and a second section. The first section can be directed towards the front and the second section towards the base.

[0083] It is possible for sections of the rotor to have different diameters. Preferably, the first section of the rotor can have a larger diameter than a second section of the rotor.

[0084] Accordingly, it is conceivable that the stator has different wall thicknesses. For example, the wall thickness of the stator where it surrounds the first section of the rotor may be less than the wall thickness where it surrounds the second section of the rotor.

[0085] The first section may be made of a different material, in particular a harder and / or stronger material, than the second section. Specifically, the first section may be made of a ceramic material and / or serve as a drill guard.

[0086] The second section preferably accommodates the electromechanical actuator and / or the control device for controlling the actuator.

[0087] The second section preferentially incorporates the blocking element.

[0088] Preferably, the locking element is mounted in the second section.

[0089] Preferably, where the stator surrounds the second section, at least one opening, preferably several openings, for the fastening element is arranged.

[0090] The first section contains, in particular, the transmission device and / or the key channel.

[0091] Preferably, the extension element extends from the first section to the second section.

[0092] The rotor may comprise a first rotor element and a second rotor element. Preferably, the first rotor element and the second rotor element are reversibly and detachably connected to each other. The first rotor element may comprise the first section. The second rotor element may comprise the second section.

[0093] The first rotor element may comprise an end surface facing the second rotor element. The end surface may preferably define the axial position relative to the stator in a spatial direction.

[0094] It may be provided that the second rotor element encompasses the projection towards the system on the base side.

[0095] Due to the projection of the second rotor element and an axial fastening of the first rotor element, for example the end face of the first rotor element or a snap ring, it is possible to insert the first rotor part from the front and the second rotor part from the bottom into the stator, in particular into the stator body. Once the first and second rotor parts are connected, the rotor is axially fixed to the rotor axis.

[0096] In particular, the rotor elements can be reversibly and detachedly connected to one another. The reversibly detachable connection can be achieved through a form-fit and / or force-fit. The reversibility can be provided, in particular, in the direction of rotation, and preferably also in the axial direction. This means that a defective rotor element can be replaced.

[0097] It can be provided that the first rotor element comprises a first fastening means and the second rotor element comprises a second fastening means, wherein the rotor elements are attached to each other in the direction of rotation by the first and the second fastening means in a form-fit and / or force-fit manner, preferably in a form-fit manner.

[0098] It can be provided that the first and second rotor elements are connected to each other, at least indirectly in the axial direction, by a positive-locking and / or force-locking connection, preferably a positive-locking connection, for example, a snap-fit ​​connection. The locking device can include a snap-fit ​​device, wherein the first rotor element and the second rotor element are connected to each other via the snap-fit ​​device. The snap-fit ​​device can provide the snap-fit ​​connection. For example, both the first rotor element and the second rotor element are clipped to the snap-fit ​​device.

[0099] The invention also provides a cylinder-type locking device with an inserted mounting device according to the invention. The mounting device can be designed as described in this disclosure.

[0100] The locking device preferably comprises a fastening element that is inserted from the outside through a recess in the locking device into the locking device housing in order to secure the stator to the locking device housing in a rotationally fixed manner. The fastening element is preferably designed as a screw or as a clamping bolt.

[0101] The locking device housing is preferably designed without the locking element recess.

[0102] The locking device can include the coupling element. The coupling element is preferably multi-part. The coupling element can include a sliding element. The sliding element is actuated by the extension element. The coupling element can include the coupling component. Preferably, the coupling component establishes the operative connection to the driver. The coupling element can include a spring, the spring being arranged between the sliding element and the coupling component. The spring can absorb a mechanical force when the sliding element is moved by the extension element, but the movement cannot be transmitted to the coupling component. The coupling component can be arranged in a spatial configuration in which the coupling component cannot be brought into operative connection with the driver. This makes it possible for any movement of the key to act on the extension component and / or for the extension component to be formed in one piece.

[0103] The locking device can include the driver.

[0104] Finally, the invention provides a locking device system with several locking devices according to the invention. The locking devices can be configured as described in this disclosure. Their mounting devices are advantageously identical in design. In particular, the locking devices comprise different locking device housings. For example, one locking device can be configured as a double cylinder and another as a half cylinder. In another example, one locking device can be configured as a double cylinder and another as a furniture cylinder or a padlock.

[0105] Preferably, the installation device is free of mechanical coding. This means that access authorization is derived solely from the electronic data that is sent and / or received by the installation device via the transmission device. This makes it possible, in particular, to construct identical installation devices. Preferred embodiment of the invention

[0106] The invention is explained in more detail below using an exemplary embodiment. Technical features with the same function are indicated in the figures with identical reference numerals. The figures show: Preferred embodiments of the invention

[0107] The invention is explained in more detail below with reference to exemplary embodiments. Technical features with the same function are indicated in the figures by identical reference numerals. The figures show: Fig. 1 a locking device according to the invention with an installation device according to the invention and a key according to a first embodiment, Fig. 2 the locking device made of Fig. 1 , which is partially disassembled, Fig. 3 the installation device designed as an installation device made of Fig. 2 , which is also part of a locking device according to the invention, without a casing, and a coupling part Fig. 4 the installation device made of Figure 3 without casing and stator body in a partially disassembled state, Figs. 5 and 6 show selected elements of the mounting device. Fig. 4 Fig. 7 shows an installation device according to a second embodiment in a partially disassembled state without a casing, and a stator body in a partially disassembled state. Fig. 8 shows a longitudinal section through the installation device according to the invention. Figure 7 , Fig. 9 a second rotor element of the installation device made of Fig. 7Fig. 10 shows a coupling part of the locking device. Figure 1 and Fig. 11 a representation of an alternative coupling part of the locking device according to the invention.

[0108] Fig. 1 Figure 1 shows a locking device 100 in the form of a locking cylinder, as used in mortise locks to unlock or lock a building door by means of a bolt. For this purpose, the locking device 100 has a housing 101 with a recess in which a driver 103, designed as a locking lug, is rotatably arranged. The driver 103 serves to move a bolt in the locking or unlocking direction.

[0109] In the right half of the housing 101 shown here, a mounting device 1 according to a first embodiment of the invention is inserted.

[0110] According to the invention, the installation device 1 comprises its own stator 10, which is inserted into a locking device housing 101. This makes it possible to design the installation device 1 independently of the installation situation on the locking element. Thus, on the one hand, a locking device housing 101 adapted to the locking element is provided, and on the other hand, a generic installation device is provided that can be inserted into various locking device housings 101. The installation device 1 includes those elements that are necessary for locking and releasing the movement of the driver 103.

[0111] In this way, a simple-to-manufacture locking device system according to the invention with several locking devices 100 can also be provided. Here, installation devices 1 according to the invention are inserted into at least two of the following different locking device housings: into a locking device housing 101 of a double cylinder with a first length, into a locking device housing 101 of a double cylinder with a second length, into a locking device housing of a half cylinder, into a locking device housing of a furniture lock, into a locking device housing of a padlock. The driver 103 can, for example, in the case of a furniture lock, itself act as a bolt.

[0112] The installation device 1 comprises the externally arranged stator 10, in which a rotor 30 of the installation device 1 is rotatably inserted about a rotor axis 35, which coincides, for example, with the axis of rotation of the driver 103. The rotor 30 has a keyway 36 on its front face 37, facing away from the driver 103, for inserting the shaft of a key 200. The key 200 carries an electronic key secret in the form of electronic data. The user's authorization to unlock the door can be determined based on this key secret.

[0113] The key 200 is preferably designed without a mechanical coding. Accordingly, the installation device 1 according to the invention is designed without a mechanically coded locking mechanism. Thus, it is only possible to determine whether the user has authorization or not based on the electronic key secret. The keys 200 and the installation devices 1 can be mechanically identical to each other. This increases the generic application possibilities of the installation device 1.

[0114] Fig. 2Figure 1 shows the locking device 100, which is partially disassembled. The housing 101 has openings 104 in its lower area, for example in both halves of the recess for the driver 103, the right-hand opening of which is marked with a reference numeral. The openings 104 extend perpendicular to the axis of rotation of the driver 103. The openings 104 serve to fasten the installation element 1 in the locking device housing 101 by means of a fastening element 102.

[0115] The driver 103 has, by way of example, an internal contour that is not circular in cross-section, for example in the form of an internal toothing, into which an insert 105 preferably engages in a form-fitting manner. The insert 105 has an external contour that is preferably complementary to the internal contour of the driver 103, here in the form of external toothing, so that both parts 103 and 105 are arranged in a rotationally fixed manner relative to each other.

[0116] A connecting section 38 of the installation device 1 projects into the insert 105. A coupling part 41 is slidably arranged in a guide 42 within the connecting section 38. The coupling part 41 is multi-part. Depending on its position, the coupling part 41 can establish or release an operative connection between the rotor 30 and the driver 103, particularly via the insert 105. For this purpose, the coupling part 41 of the locking device 100 can engage positively in an inner contour of the insert 105 (not shown). The guide 42 preferably forms a linear guide for the coupling part 41, so that the coupling part 41 is movably guided along the rotor axis 35 of the rotor 30. In a coupled state, the coupling part 41 is located both in the guide 42 and in operative connection with the driver 103, with the coupling part 41 being slightly disengaged.In the disengaged state, the coupling part 41 is recessed in the guide 42, so that the operative connection with the driver 103 is terminated.

[0117] The installation device 1 is designed in such a way that different coupling parts 41 can interact with the installation device 1. In particular, different coupling parts 41 can be arranged in the guide 42. This allows for different functions in the locking device. The guide 42 is arranged outside the stator 10, so that different coupling parts 41 can be easily used.

[0118] If the mounting device 1 is to be rigidly connected to the driver 103, this can also be done using the guide 42. A connecting element (not shown) can be inserted into the guide 42 to establish the rigid connection to the driver. It is also possible to insert a cam into the guide 42 that always rotates with the rotor 30, but only engages the driver 103 within a predetermined angular range.

[0119] The mounting device 1 has a sleeve 14, with which the mounting device 1 is inserted into a corresponding insertion opening 106 of the housing 101. The fastening element 102, shown here by way of example in the form of a screw, is screwed in through the recess 104 on the right from the underside of the housing 101 and through an opening 21 on the left in the sleeve 14 of the stator 10 and a stator body 11 of the stator 10, which will be explained in more detail later. The fastening element 102 thus secures the stator 10 in the housing 101. Also shown here is the keyway 36 for inserting the key 200, which is formed in a first rotor element 32 of the rotor 30.

[0120] The opening 21 is formed in both the shell 14 and the stator body 11.

[0121] The opening 21 is provided in a part of the stator body 11 that has a greater wall thickness than another part of the stator body 11. The opening 21 is formed in the part of the stator 11 with the greater wall thickness, thus ensuring secure fastening of the installation element 1 in the locking device housing 101. Preferably, several openings 21 are provided to fasten the installation element 1 in different locking device housings 101 and / or with different fastening elements 102 (see figure). Fig. 2 and 8 ).

[0122] The rotor 30 is freely rotatable in the stator body 11 of the stator 10, but is fixed in position in the direction of its rotor axis 35, which runs parallel to the insertion direction of the key 200 into the key channel 36.

[0123] Fig. 3Figure 1 shows that the stator 10 is cylindrical. The shell 14, not shown, is adapted to the contour of the stator body 11 (see also Figure 1). Figure 8 This makes it particularly easy to insert the stator 10 into different, but easy-to-manufacture, locking device housings 101.

[0124] In Fig. 3 The installation device 1 is shown without the casing 14 and the coupling part 41. Fig. 4 The installation device 1 is shown without casing 14 and without stator body 11 in a partially disassembled state.

[0125] The rotor 30 comprises a first rotor element 32 and a second rotor element 33. The first rotor element 32 forms a first section of the rotor 30 and the second rotor element 33 forms a second section of the rotor 30.

[0126] During assembly, the first rotor element 32 can be inserted into the stator 10 from the front side 37. The first rotor element 32 is connected by an end surface 66 facing the second rotor element 33 (see figure). Fig. 4 ) axially towards the driver 103 in the direction of arrow 79. Here, the end surface 66 rests against an internal structure of the stator 10, in particular the stator body 11.

[0127] A fully formed lead 43 (see Fig. 4 The collar of the second rotor element 33 serves as a stop for the second rotor element 33 against the stator 10. The second rotor element 33 can be inserted from a base side 23 of the stator 10 until the projection 43 abuts the base side 23. The projection 43 is preferably formed integrally with the second rotor element 33. Due to this integral design, the second rotor element 33 can only be inserted into the stator 10 from the base side 23.

[0128] The insertion of the rotor 30 or the rotor element 33 from the base side 23 is particularly facilitated by the division into the insert element 1 and the locking device housing 101.

[0129] The projection 43, positioned against the base 23, fixes the second rotor element 33 axially towards the front 37, opposite to the direction of arrow 79. During assembly, the second rotor element 33 is inserted into the stator 10 from a base 23 without the first rotor element 32. The projection 43 provides additional installation space within the rotor 30.

[0130] The first and second rotor elements 32, 33 are connected to each other in a rotationally fixed manner after insertion, particularly in a reversible manner. The division into rotor elements 32, 33 makes assembly of the rotor 30 particularly easy. By connecting the two rotor elements 32, 33, the resulting rotor 30 is axially fixed forwards and backwards, i.e., with and against the direction of arrow 79.

[0131] The rotor elements 32, 33 are cylindrical in shape. The first rotor element 32 has an inner contour into which the second rotor element 33 is inserted.

[0132] The rotor elements 32 and 33 can be made of different materials. For example, the first rotor element 32 is made of a harder or more wear-resistant material than the second rotor element 33. This is particularly advantageous because the first rotor element 32 is designed to hold the key 200 and is therefore subject to greater mechanical stresses than the second rotor element 33. This also allows for a simple way to implement drill protection. For example, the first rotor element 32 can be made of a ceramic material.

[0133] The coupling part 41 is arranged in a rotationally fixed manner on the second rotor element 33 of the rotor 30 of the installation device 1. The second rotor element 33 has the guide 42 into which the coupling part 41 engages and is thus arranged in a rotationally fixed manner relative to the second rotor element 33.

[0134] The stator body 11 is designed in a sleeve-like form. The first rotor element 32 has a larger diameter than the second rotor element 33. As a result, the part of the stator body 11 surrounding the second rotor element 33 has a greater wall thickness than the part surrounding the first rotor element 32. Consequently, the stator body 11 has a greater wall thickness in the area of ​​the second rotor element 33 than in the area of ​​the first rotor element 32.

[0135] The rotor, in particular the second rotor element 33, houses an actuator assembly 50 in an installation space 82 (see Fig. 7The actuator group 50 comprises an electromechanical actuator 52, here in the form of an electric motor, on whose output shaft a locking element 51 is arranged in a rotationally fixed manner. The locking element 51 includes a recess 54, which will be explained in more detail later. In addition, the second rotor element 33 houses an electronic control device 53 for controlling the actuator 52.

[0136] A locking element 31 is mounted in the rotor 30, in particular in the second rotor element 33, preferably perpendicular to the rotor axis 35, so as to be linearly movable towards and away from the blocking element 51. In a Figure 5 In the first position shown, the locking element 31 is located in a locking element recess 15 (see. Fig. 5), which is formed by a stator insert element 13 and stator elements 12. This prevents the rotor 30, and thus the coupling part 41, from rotating relative to the stator 10. The rotation of the inserted key 200 to unlock the associated lock is blocked or prevented. In a second position of the locking element 31 (not shown), the locking element 31 is disengaged from the locking element recess 15 of the stator 10. This allows the rotor 30, and thus the driver 103, to rotate within the stator 10.

[0137] The locking element recess 15 is closed to the outside, i.e., towards the locking device housing 101. Thus, the locking element 31 is located completely within the mounting device 1 in both the first and second positions. Therefore, it is not necessary to provide a locking element recess in the locking device housing 101. In the embodiments presented here, the locking element recess 15 is bounded to the outside at least by the sleeve 14, and preferably also by the stator insert element 13.

[0138] The locking element 31 is guided in a guide 81. Because the second rotor element 33 forms the installation space 82 and the guide 81, the projection 43 is integrally connected to the guide 81 and the installation space 82.

[0139] The locking element 31 is forced into the first position by at least one spring 34, preferably several springs 34. In the exemplary embodiment of the Figure 5Several springs 34 are provided. The stator, in particular the stator elements 12 and / or the stator insert element 13, limit the movement of the locking element 31 against the direction of arrow 70. The locking element 31 remains within the installation space defined by the housing 14. Thus, it is not necessary to provide a locking element recess in the locking device housing 101.

[0140] The stator elements 12 and the stator insert element 13 are arranged in the section of the stator 10 that surrounds the second rotor element 33. The small diameter of the second rotor element 33 makes it possible to position the movable stator elements 12 within the stator 10.

[0141] The locking element 51 is rotatable between a release position, in which the recess 54 is opposite the locking element 31, so that the locking element 31 can move into the recess 54, and locking positions, in which the recess 54 is not opposite the locking element 31, so that the locking element 31 is prevented from moving into the recess 54. Figure 4 and 5 The blocking positions of the blocking element 51 are shown.

[0142] The locking element 31 is designed at its section 63 facing the blocking element 51 to be able to move into the recess 54 when the blocking element 51 is in the release position and the recess 54 is opposite the section 63 of the locking element 31. Figure 5 so pointing upwards. This makes it possible for the locking element 31 to move into the second position.

[0143] A first contact surface 16 of the stator elements 12, facing the locking element 31, is designed to force the locking element 31 towards the blocking element 51, i.e., into the second position, when the rotor 30 rotates, in which the rotor 30 is freely rotatable relative to the stator 10. The first contact surface 16 is designed as an inclined surface that forces the locking element 31 into the second position.

[0144] The stator elements 12 are movably mounted on the stator insert element 13 between a first position and a second position. The stator elements 12 are forced into the first position by means of spring elements 18. The spring elements 18 are mounted in the stator 10. The movement of the stator elements 12 from the first position to the second position in the direction of movement 71 is perpendicular to the direction of movement 70 of the locking element 31.

[0145] In the unlocking sequence of the rotor 30 relative to the stator 10, the locking element 31 is initially located in the locking element recess 15. Here, the locking element 31 is guided in the second rotor element 33. Additionally, the locking element 31 rests against the first contact surfaces 16 of the stator elements 12. Thus, the contact surfaces 16 act as boundary surfaces that limit the outward movement of the locking element 31. The contact against the contact surfaces 16 centers the locking element 31. This position of the locking element 31 is referred to as the rest position. In the rest position, the locking element 31 is preferably arranged at a distance from the locking element 51.

[0146] A user now wants to unlock the door and inserts the key 200 into the key channel 36. This initiates electronic communication between the key and the control device 53, which electronically determines whether the user is authorized.

[0147] If the user is authorized to unlock the door, the control device 53 activates the actuator 52. The actuator 52, designed as an electric motor, rotates the locking element 51 into the release position, in which the recess 54 is opposite the locking element 31. If the rotor 30 is now turned using the key 200, the locking element 31 slides along one of the first contact surfaces 16 into the second position, in which the locking element 31 engages in the recess 54. This tensions the springs 34. The locking element 31 moves in the direction of movement 70.

[0148] The stator elements 12 remain in the first position. This is made possible by the fact that the spring elements 18 exert a higher force on the stator element 12, along which the locking element 31 slides, than the springs 34 exert on the locking element 31.

[0149] The rotor 30 is now freely rotatable. The locking element 31 slides along the first contact surface 16 into which it is rotated. The locking element 31 is surrounded by the first contact surfaces 16 in both directions of rotation, so that when it comes into contact with one of the first contact surfaces 16, rotation in either direction moves the locking element 31 into the second position. To ensure that first contact surfaces 16 are present in both directions of rotation, the locking element recess 15 is surrounded on both sides by stator elements 12.

[0150] The stator 10 has secondary contact surfaces 17 that hold the locking element 31 in the first position. These secondary contact surfaces 17 are functionally used when the user is not authorized to unlock the door. The secondary contact surfaces 17 are formed in the stator insert element 13. When the locking element 31 is in its rest position, the secondary contact surfaces 17 are further engaged by the locking element 31 than the primary contact surfaces 16.

[0151] Preferably the second mounting surfaces 17 are also inclined, but in the opposite direction to the first mounting surfaces 16 with respect to the direction of movement 70 of the locking element 31.

[0152] At its end facing the stator insert element 13, the locking element 31, viewed along the axis of rotation of the blocking element 51 and / or the rotor axis 35, has a cross-section in the form of a preferably symmetrical trapezoid that tapers towards the blocking element 51. The legs of this trapezoid form end faces 60 outwards with respect to the locking element 31. The end face 60 and the corresponding contact surface 17 are inclined towards the direction of movement of the locking element 31.

[0153] If the user is not authorized to unlock the door, the following sequence occurs. The locking element 31 is initially in its rest position. A key 200 without authorization is inserted into the key channel 36. The electronic data exchange indicates that there is no authorization to unlock the door. Therefore, the actuator 52 is not activated, and the blocking element 51 remains in a blocking position in which the recess 54 is not opposite the locking element 31, as shown in Figure 4 and 5 as shown. Rather, an outer circumference of the blocking element 51 is opposite the locking element 31.

[0154] When the rotor 30 is rotated, the locking element 31 attempts to slide along the first contact surface 16. However, this fails because the locking element 31 rests on an outer circumference of the blocking element 31. Thus, the locking element 31 cannot be forced into the second position against the force of the springs 34.

[0155] Instead, the stator element 12, which is located in the direction of rotation of the locking element 31, is pushed back by the locking element 31 against the force of the spring 18 until the locking element 31 rests against the second contact surface 17. The stator element 12 is now in the second position.

[0156] In this process, the head surface 60 of the locking element 31 comes into contact with the corresponding second contact surface 17, which is opposite one of the legs of the trapezoid.

[0157] In this state, the stator element 12 or stator elements 12 have been moved back in the direction of rotation against the force of a spring element 18. As the rotor 30 continues to rotate, the spring element 18 presses the stator element 12 against the locking element 31.

[0158] The contact surface 17 is designed such that it holds the locking element 31 in the first position. Thus, the rotor 30 remains blocked by the locking element 31, preventing the door from unlocking.

[0159] Every second contact surface 17 corresponds to a respective head surface 60 of the locking element 31 facing the other. The surface 60 and the respective corresponding contact surface 17 are designed such that the contact surface 17 is located between the surface 60 and the blocking element 51 when the locking element 31 is in contact with the contact surface 17.

[0160] If an attempt is made to rotate the rotor 30 further, the locking element 31 slides away from the blocking element 51 in the opposite direction of movement 70. This is achieved by the slope of the second contact surface 17. The locking element 31 can slide along the second contact surface 17 with its head surface 60. Thus, the locking element 31 and the blocking element 51 can be spaced apart from each other when in contact with the second contact surface 17. Additionally or alternatively, the forces acting on the locking element 31 during further attempted rotation of the rotor 30 are transferred into the second contact surface 17. This is facilitated by the fact that the head surfaces 60 correspond to the second contact surfaces, and thus the locking element 31 rests flat against the second contact surface.

[0161] In Fig. 5 The locking element recess is marked with the reference number 15. Fig. 6 shows the arrangement of Fig. 5Viewed from one end face of the locking element 31, but without the blocking element 51. Here, the stator elements 12 are in the second position.

[0162] The locking element 31 is surrounded in both directions of rotation by the second contact surfaces 17, so that when the locking element 31 comes into contact with one of the second contact surfaces 16 during rotation in both directions, it remains in the first position.

[0163] In the first position of the stator elements 12, the first contact surfaces 16 are located closer to the locking element 31 than the second contact surfaces 17. In the second position of the stator elements, the second contact surfaces 17 protrude further into the locking element recess 15 than the first contact surfaces 16.

[0164] The locking element 31 is formed in one piece. This means that the first contact sections 64 of the locking element 31, which serve to contact the first contact surfaces 16, are rigidly connected to the end surfaces 60, which serve to contact the second contact surfaces 17. The end surfaces 60 thus serve as the second contact sections. The first and second contact sections 60, 64 are rigidly connected to the third contact section 63 of the locking element, which serves to contact the recess 54.

[0165] The stator elements 12 and the stator insert element 13 are arranged in the section of the stator 10 that surrounds the second rotor element 33. Due to the small diameter of the second rotor element 33, it is possible to integrate the first and second system sections 16, 17 into the stator 10.

[0166] The fact that the stator comprises a stator body 11 and the stator insert element 13 simplifies the installation of the mounting element 1. The sleeve 14 serves to secure the stator insert element 13 in the stator body 11. The stator body 11 has a stator recess 19 into which the stator insert element 13 is inserted. The sleeve 14 covers the stator insert element 13.

[0167] Figure 5 shows selected elements of the installation device 1 from Fig. 4 . This shows Fig. 5 the arrangement the locking element 31 in relation to the blocking element 51 and the stator insert element 13 together with stator elements 12.

[0168] A transmission element 44, here for example in the form of a coil, is provided to establish a data and / or power transmission connection with the key 200. This makes it possible to read electronic data, such as authentication information or an opening command, from or receive it from the key 200. The electronic control device 53 is coupled to the transmission element 44 to read and, if necessary, evaluate the data. If the control device 53 checks that the user of the key 200 is authorized to open the corresponding door, and / or if the control device 53 has received an opening command, an electromechanical actuator assembly 50 is activated.

[0169] The transmission element 44 is arranged in the first rotor element 32.

[0170] The key channel 36 is provided in the first rotor element 32. Thus, the key channel 36 ends before the actuator 52. The key channel 36 ends before the control device 53. This increases the tamper resistance.

[0171] An extension element 40 is designed to interact mechanically with the key 200. When the key 200 is inserted into the key channel 36, it moves the extension element 40 axially, or parallel to the rotor axis 35, into an insertion position upon contact.

[0172] Preferably, the extension element 40 moves the coupling element 41 away from the rotor 30 and towards the driver 103, so that the coupling element 41 can engage in rotation with the driver 103. A passage 39 is provided in the connecting section 38 to allow the extension element 40 to come into contact with the coupling element 41. Either the extension element 40 or the coupling element 41 can protrude through the passage 39.

[0173] When the key is removed, the extension element 40 moves axially to the rotor axis in a second direction, opposite to the first direction, into a release position. The extension element 40 is forced into the release position by a force storage device 49.

[0174] The extension element 40 extends from the first rotor element 32 to the second rotor element 33. This allows the extension element to bridge a gap between the inserted key 200 and / or the key channel 36 and the coupling part 41. This extends the effective range of the key 200.

[0175] The first rotor element 32 surrounds the extension element 40 radially.

[0176] The second rotor element 33 includes a guide 65 to axially guide the extension element 40 between the pull-out position and the insertion position.

[0177] In the example shown, the extension element 40 is angled. A first part of the extension element 40, which is intended for interaction with the key 200, extends radially further outwards than a second part of the extension element 40, which is intended for interaction with the coupling part 41. This allows the second part to be positioned more centrally, making it easier to slide the coupling part 41.

[0178] The extension element 40 is designed to push the coupling part 41, but without engaging with it in a positive-locking manner. Thus, the extension element 40 is movable independently of the coupling part 41. Rather, when the key is removed, the coupling part 41 initially remains engaged.

[0179] This allows the extension element to be designed with a delicate structure.

[0180] A torque is transmitted from the key 200 to the rotor 30 and then to the coupling part 41. No torque transmission occurs via the extension element 40. Instead, the torque is transmitted from the first rotor element 32 to the second rotor element 33, whose guide 42 leads to the coupling part 41. From the coupling part 41, the torque is transmitted via the insert 105 to the driver 103.

[0181] The extension element 40 serves to mechanically and / or magnetically return the locking element 51 from the release position to the locking position. In this way, the extension element 40 can be moved back to the release position when the key is removed. When the extension element moves to the release position, a movement of the locking element 51 into the locking position can be caused or permitted. For example, as described in the second embodiment in Figure 7The spring shown is tensioned during the movement of the locking element 51 into the release position. With the key inserted, the extension element 40 holds the locking element 51 in the release position and allows the locking element 51 to return to the locking position when the extension element 40, with the key 200, moves towards the front 37 during key removal.

[0182] A locking element 61 is provided which holds the rotor 30 in position relative to the stator 10.

[0183] The detent element 61 is formed by means of a spring-loaded detent lug. This means that the rotor 30 can overcome the detent lug 61 during rotation, thus maintaining the function of the rotor 30. The detent lug 61 provides haptic feedback to the user that a desired position has been reached. The detent element 61 is arranged to be axially movable. This axial movement of the detent element 61 is made possible by the different diameters of the rotor elements 32 and 33.

[0184] The locking element 61 is movably mounted in an opening (not shown) of the stator 10, in particular of the stator body 11. The opening is open to the outside, so that the casing 14 limits the outward movement of the locking element 61. The opening is partially closed to the inside, so that the locking element 61 is guided in the stator body 11, but is partially open axially and / or inwards, so that the locking element 61 can engage with the rotor 30.

[0185] Furthermore, the locking lug 61 defines a position in which the key 200 can be inserted and removed. In this position, the locking element 31 is in its rest position, spaced apart from the blocking element 51, so that the actuator 52 can rotate the blocking element 51.

[0186] The locking element 61 is provided on the first rotor element 32.

[0187] The locking element 61 is axially movable. This is made possible by the different diameters of the first and second rotor elements 32, 33.

[0188] An annular projection 22 is formed by means of, in particular, half-shell-shaped parts, the mutually facing inner surfaces 26 of which interact with the key 200 in a bayonet-like manner. The parts are inserted into a circumferential groove 45 of the first rotor element 32. Outwardly projecting projections 25 of the annular projection 22 fix the parts of the projection 22 in the stator body 11 in their relative position to each other and to the stator body 11. The annular projection 22, with the inserted key 200, preferably acts in a bayonet-like manner as a key removal lock.

[0189] The projection 22 has a first protective element part 87 and a second protective element part 90. The protective element parts 87 and 90 have the shape of a half-ring and / or a rectangular ring cross-section. On the outer circumferential surface of the protective element parts 87 and 90 are the projections 25, which engage in recesses in the stator when the protective element parts 87 and 90 are mounted thereon.

[0190] The Figures 7 to 9 Figure 1 shows a further embodiment of a mounting device designed as a mounting device. Unless otherwise described below, the second embodiment corresponds to the first embodiment.

[0191] Figure 7 The figure shows the installation device 1 without casing 14 and stator body 11 in a partially disassembled state. Fig. 8 shows a cross-sectional view.

[0192] Instead of the screw 24, the first rotor element 32 comprises fastening means 67 and the second rotor element 33 comprises corresponding fastening means 68, which interlock positively, so that the first rotor element 32 and the second rotor element 33 are fixed to each other in a rotationally fixed manner. The first and second fastening means 67, 68 are designed as projections and corresponding recesses.

[0193] Instead of the coil as transmission device 44, contact elements are provided which transmit data and / or electrical energy to the installation device 1 via an electrical contact with the key 200. The contact elements 44 are spring-loaded on a housing 46.

[0194] The housing 46 also serves to axially fasten the rotor elements 32, 33 to one another. Thus, the housing 46 acts as a locking device. For this purpose, the housing 46 includes a first locking element 47, which engages in the first rotor element 32. The first rotor element 32 has an edge 78 for this purpose. The housing 46 includes a second locking element 48, which engages in the second rotor element 33. The second rotor element 33 has a groove 77 for this purpose.

[0195] The first rotor element 32 is axially fixed by a snap ring 72, both in the direction of arrow 79 and against the direction of arrow 79. The snap ring 72 is arranged in a groove 73 of the first rotor element 33.

[0196] The locking element 61 is arranged in the stator 10 and engages in a recess 69 of the first rotor element 32.

[0197] As in the first embodiment, the extension element 40 is moved into the trigger position by the spring 49. The extension element 40 also includes a spring-loaded engagement element 74. The engagement element 74 is designed to engage with the key 200. By engaging the key 200, the extension element 40 can be moved from the insertion position to the trigger position when the key is pulled, for example, if movement by the spring 49 has been prevented by manipulation.

[0198] The engagement of the engagement element 74 occurs when, in the insertion position, the engagement element 74 rests against an inner surface 75 of the stator body 11, which the second rotor element 33 abuts against the spring action of the engagement element 74, and is forced into engagement with the key 200. In the withdrawal position, which is in Figure 8In contrast, as shown, the engagement element 74 is located in a cavity 76 inside the first rotor element 32. This makes it possible for the engagement element 74 to slide out of the key 200 due to the spring force and / or chamfers.

[0199] The cavity 76 transitions into the keyway 36.

[0200] Figure 9 Figure 1 shows the second rotor element 33. A groove 77, designed for engagement with the locking element 48, is shown. The groove 77 also serves as a predetermined breaking point. In the event of an attempted tampering, the second rotor element 33 breaks apart at the groove 77, with the essential part of the second rotor element 33, including the control device 53 and the actuator group 50, remaining in the stator 10.

[0201] In the second embodiment of the Figures 7 to 9A spring device 88 is provided. The spring device 88 is designed as a leaf spring adapted to the contour of the projection 22, the projection 22 being inserted in a groove 45 of the rotor 30, in particular of the first rotor element 32. This results in simple assembly, since the spring device 88 clamps the projection 22 to the first rotor element 32 similarly to a snap ring. However, the rotor 30 can be rotated without the projection 22 and the spring device 88 rotating with it, so that during rotation of the key 200, the projection 22 is fixed against rotation in the stator 10.

[0202] The spring device 88 is adapted to the contour of the projection 22 and is applied to its outer circumference. Thus, the projection 22 and the spring device 88 are designed in such a way that they are particularly small and easy to assemble.

[0203] As in Figure 10As shown, the coupling part 41 is designed in multiple parts. The coupling part 41 comprises a sliding element 91, a coupling element 92, and a spring 93. The sliding element 91 is guided in a channel 38a of the connecting section 38.

[0204] The sliding element 91 is displaced by the extension element 40 when the extension element 40 moves from the withdrawal position to the insertion position. The coupling element 92 is designed to be guided in the guide 42 and to be in a coupling position in operative connection with the driver 103. When the key 200 is inserted and the sliding element 91 is displaced, and the insert 105 and the coupling element 92 are in a geometrically compatible spatial position relative to each other, the coupling element 92 is also displaced by the spring 93, so that the coupling element 92 enters the coupling position, i.e., engages with the insert 105 and thus is in operative connection with the driver 103.If the sliding element 91 is moved when the key 200 is inserted, and the insert 105 and the coupling element 92 are in a geometrically misaligned position relative to each other, the spring 93 is tensioned and the coupling element 92 initially remains in a disengaged position until the insert 105 and the coupling element 92 can assume a geometrically compatible position relative to each other and the coupling element 92 is forced into the engaged position by the force of the spring 93. In both the engaged and disengaged positions, the coupling element 92 is arranged in the guide 42. In the disengaged position, the coupling element 92 is further away from the driver 103 than in the engaged position.

[0205] To allow for a small installation space for the locking device 1, the key 200 is designed to push the extension element 40 into the insertion position without an intermediate energy storage device. The extension element 40 then pushes the coupling part 41 without an intermediate energy storage device. The energy storage device, in the form of the spring 93, is instead located outside the interior of the locking device 1 in the connecting section 38.

[0206] The extension element 40 is designed to push the coupling part 41, but without engaging with it in a positive-locking manner. For this purpose, the extension element includes a section 86. Thus, the extension element 40 is movable independently of the coupling part 41. Rather, when the key is removed, the coupling element 92 initially remains in the engaged position. However, in the disengaged position, the extension element allows the coupling element 92 to move into the disengaged position. This connects the driver 103 to the stator 10 via the coupling element 92, the second rotor element 33, and the locking element 31, preventing the driver 103 from rotating when the key is removed. This provides effective tamper protection.

[0207] Movement of the coupling element 92 into the uncoupling position can be effected, for example, by pressing on a further sliding element 94. The sliding element 94 can, for instance, be part of another locking device on the other side of the door. When a key is inserted into the further locking device, the sliding element 94 is moved. This, either directly or by tensioning a further spring 96, pushes another coupling element 95 into a coupling position with the driver 103. At least when the key of the locking device 100 according to the invention is removed, the coupling element 92 is moved from the coupling position to the uncoupling position.

[0208] In Figure 11 Figure 1 shows a further embodiment of a coupling part 41 of a locking device 100 according to the invention. For example, the coupling part 41 of the Figure 11This is used when a knob is used on the other side of the door. The knob is firmly connected to the follower 103. When the key 200 is removed from the locking device 100 according to the invention and the extension element 40 is moved into the removal position, the force of the spring 96 pushes the coupling element 92 into the uncoupling position.

[0209] The installation device 1 according to the first or the second embodiment can also be used in other locking devices, for example in a half cylinder, a knob cylinder, a furniture cylinder or a padlock.

[0210] It is conceivable that the coupling part 41 is missing in the installation device 1 according to the invention. Instead, locking devices according to the invention can be provided in which the driver 103 is rigidly attached to the rotor 30. The driver 103 can also itself serve as a bolt, e.g., in a furniture lock. The driver 103 and the insert 105 can be formed integrally.

[0211] The stator insert element 13 and the stator body 11 can be formed as a single piece. It is also conceivable that the casing 14 is omitted and the stator body is directly attached to the locking device housing 101.

[0212] The actuator may move the locking element 51 back into the locking position. This may be the case, in particular, with knob cylinders.

[0213] The blocking element 51 can alternatively be designed in the form of a plunger. In this case, a preferably bistable magnet is suitable as the actuator. The plunger can be spring-loaded in one direction, preferably in the direction away from the magnet.

[0214] Elements of the first embodiment can be implemented in the second embodiment and vice versa. For example, the second embodiment can include a coil as a transmission device 44, or the first embodiment can include contact elements as a transmission device 44. For example, the rotor elements 32, 33 of the first embodiment can be attached to one another as in the second embodiment. The extension element 40 of the first and second embodiments can be interchanged. The axial fixing of the first rotor element 32 with respect to the stator can be carried out according to either the first or the second embodiment.

[0215] The installation device 1 according to the invention can be inserted into a switching element housing (not shown). This results in a switching element that can only trigger a switching operation if the user has electronic authorization. A driver that rotates with the rotor 30 is used to actuate a switch. Due to the installation device 1 according to the invention, it is not necessary to provide a locking element recess in the switching element housing itself. Rather, the stator 10 and the switching element housing together form a stationary component.
