Description

The invention relates to an electromechanical installation device for insertion in a lock cylinder-like locking device or in a switching element according to claim 1. The invention also relates to a lock cylinder-like locking device equipped with such an installation device. Finally, the invention relates to a locking device system with a plurality of locking devices, each of which includes an installation device.

State of the art

The EP 1 914 368 B1 discloses a lock cylinder as a locking device with a blocking element which, in a first position, is located both in a rotor and in a lock cylinder housing and thus blocks rotation of the rotor relative to the lock cylinder housing. Here, the blocking element engages in a recess of the lock cylinder housing. In a second position of the blocking element, on the other hand, the blocking element is located completely in the rotor, so that the rotor can be rotated relative to the lock cylinder housing. The disadvantage of this is that the lock cylinder housing must have a recess for the blocking element. Therefore, individual different lock cylinder housings must each have a recess.

It is therefore the object of the present invention to further develop components for a locking device, a locking device and a locking device system such that it can be manufactured more easily and/or more flexibly.

Disclosure of Invention

The object is achieved by independent claim 1. Advantageous developments of the device are specified in the dependent device claims, the description and in the figures. Furthermore, the object is also achieved by a locking device according to claim 13. Advantageous developments of the locking device are specified in the associated dependent device claim, the description and in the figures. In addition, the object is also achieved by a locking device system according to claim 15. Advantageous developments of the locking device system are specified in the description and in the figures. Features and details that are described in connection with the installation device according to the invention also apply vice versa in connection with the locking device according to the invention and/or the locking device system. The features mentioned in the description and in the claims can each be essential to the invention individually or in combination.

According to the invention, an electromechanical built-in device is provided for use in a lock cylinder-like locking device or in a switching element with a stator having a rotor as components. The stator is used for insertion into a locking device housing or into a switching element housing. Furthermore, the installation device is provided with a blocking element. The rotor is mounted in the stator, in particular rotatably. The blocking element is mounted in one of the components, in particular so that it can move linearly, and can be moved between a first position and a second position. In the first position, the blocking element blocks rotation of the rotor in the stator. In the second position, the locking element allows the rotor to rotate in the stator.

In the first position, the blocking element preferably engages in a blocking element recess of the other component. As a result, the blocking element can preferably connect the rotor and the stator. Because the blocking element is partially arranged in the stator at least in the first position and the stator is designed to be inserted into a locking device housing, it is not necessary to make a recess or bearing for the blocking element in the locking device housing. Rather, a separate component is provided with the stator, which is inserted into a locking device housing, which interacts with the locking element and can thus prevent rotation of the rotor.

The first component can correspond to the rotor or the stator. Correspondingly, the second component corresponds to the other of the components, i. H. either the stator or the rotor. Thus, either the blocking element can be mounted in the rotor and can engage in the stator in the first position, or the blocking element is mounted in the stator and can engage in the rotor in the first position.

The blocking element is preferably mounted in the rotor. The stator preferably includes a blocking element recess in which the blocking element engages in the first position. i.e. the blocking element is housed in the rotor, which has the advantage that the stator can be made relatively thin. In the second position, the blocking element is preferably disengaged from the blocking element recess.

In the first position, the blocking element preferably protrudes into the blocking element recess. However, the blocking element preferably does not protrude beyond the outer circumference of the stator in the first position. In the first position, the blocking element is preferably arranged in an installation space which is delimited by the outer circumference of the stator. The housing of the locking device or switching element can thus be free of a recess for the blocking element.

Provision can be made for the blocking element to be tensioned in the first position by at least one spring in the direction of the first position. The blocking element preferably moves from the first position to the second position in a direction of movement. The installation device, in particular the stator, preferably comprises an interface on which the locking element rests in the first position and which prevents the movement of the locking element against the direction of movement, ie. H. when moving to the first position.

The locking device with the built-in device preferably serves to lock a spatial area. In particular, the spatial area is fixed. For example, the physical area may be a building space, such as an office, apartment, or house, or a storage space, such as a closet, mailbox, chest, box, safe, or drawer. In particular, the locking device serves to be used in a door-like locking element, for example a front door, an apartment door, a room door, a cupboard door, a mailbox flap or the front of a drawer, or to be attached to a locking element.

The stator of the built-in device is preferably connected at least indirectly in a rotationally fixed manner to the closure element. The locking device housing is preferably non-rotatably connected to the locking element.

The locking device can have a driver or can be connected to a driver. A rotation of the rotor of the installation device serves to rotate the driver.

The driver is preferably designed as an eccentric. The driver can be designed as a locking lug. It may be that a rotation of the driver in a first direction is used to convert the closure element from an unlocked state to a locked state. It may be that a rotation of the driver in a second direction serves to convert the closure element from a locked to an unlocked state. For example, the installation device can be used at least indirectly in a mortise lock. In this case, a rotation of the driver can cause the bolt of the mortise lock to move. So the rotation of the driver in a first direction z. B. an extension of the bolt and thus bringing about the locked state of the closure element. A rotation of the driver in a second direction can, for. B. bring about a retraction of the bolt and thus bringing about the unlocked state of the closure element.

Alternatively, the driver itself can act as a latch. So the rotation of the driver in a first direction z. B. cause the driver to assume a locked position.

The rotation of the driver in a second direction can, for. B. cause the driver to assume an unlocked position.

The closure device housing is used in particular for insertion into or attachment to the closure element. The locking device can be designed, for example, 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.

Alternatively, the installation device can be provided for a switching element. The switching element can only be operated by authorized users. A driver of the switching element can be used to actuate a switch or button. The built-in device can thus be used in a switching element, in particular in a key switch, or can correspond to a key switch.

The installation device, in particular the rotor, can be connected or can be connected to a knob or a key in order to transmit a mechanical torque to the rotor. If interaction with a key is provided, the installation device, in particular the rotor, can include a key channel.

It is preferably provided that the installation device comprises a connecting section in order to be connected to a driver.

The electromechanical installation device includes an electromechanical actuator. The actuator can be designed in particular as an electric motor.

The actuator serves to make it possible for the driver to be movable when the rotor rotates.

The actuator serves to enable the locking element to be moved to the second position.

The built-in device can include an electronic control device, in particular a processor and/or a controller, in order to control the actuator. The control device may include an electronic memory.

The mounting device may include a transmission device. The transmission device can be designed as a transmitting and receiving unit, as a biometric sensor, as a keypad for entering a PIN and/or as a contact element for making electrical contact with a key, in particular an electronic key. The transmitting and receiving unit can be designed to communicate with a mobile unit, in particular a mobile phone or a card, by wireless short-range communication, in particular RFID or Bluetooth Low Energy.

The transmission device can be used to send and/or receive electronic data that make it possible to determine whether a user is authorized to unlock the spatial area. 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 completed with a positive result, the actuator can be controlled to enable the driver to rotate.

Alternatively, the transmission device can transmit an opening command. The actuator can be controlled on the basis of the opening command in order to enable the driver to rotate. For example, due to the opening command, the blocking element can be moved electromechanically into the second position or the movement into the second position can be released electromechanically.

The transmission device serves in particular additionally or alternatively to transmit electrical energy to the built-in device. The electrical energy can be provided for actuating the actuator and/or for the control device.

The installation device according to the invention preferably comprises a blocking element. The blocking element can be moved into a release position by the actuator. An actuator assembly of the installation device includes the blocking element, the actuator and the blocking element.

Provision is preferably made for the blocking element to allow movement of the blocking element from the first position into the second position in a release position and to prevent movement of the blocking element from the first position into the second position in a blocking position.

In particular, it can be provided that when the blocking element is in the release position, the rotation of the rotor allows the blocking element to move into the second position. Here, in particular, the stator forces the blocking element into the second position.

The blocking element preferably comprises a recess in which the blocking element is arranged in the second position. In the first position, on the other hand, the blocking element is outside of the recess. In the release position, the blocking element is arranged in such a way that the cutout is opposite the blocking element, so that the blocking element can move into the cutout.

The actuator preferably serves to enable movement of the blocking element from the blocking position into the release position. So the actuator can move the blocking element in the release position and / or z. B. cause a movement of the blocking element in the release position by tensioning a spring.

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

The blocking element can be moved, in particular rotated, between the release position and the blocking position.

It can be provided that the blocking element is arranged on the output shaft of the actuator designed as an electric motor. The actuator preferably enables the blocking element to be rotated from the blocking position into the release position. The actuator preferably rotates the blocking element from the blocking position to the release position. This allows a very space-saving design.

The rotor preferably accommodates the electromechanical actuator and/or the blocking element.

In the case of the built-in device, the stator can be of cylindrical design. This is advantageous for mounting in a lock housing. Preferably, the stator may include at least one opening configured to receive a fastener passed through the latch housing for non-rotatably mounting the stator to the latch housing. This is a very easy way to attach the stator.

The stator may include multiple openings to accommodate a fastener used in different latch housings. This increases the flexibility of use of the built-in device.

The rotor can include a connecting section which is designed to be directed towards a driver of the locking device in the installed state.

The rotor can be designed to enter into an operative connection with a clutch part. The coupling part can be designed so that it can be brought into engagement 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 part.

The connecting section preferably includes a guide for the coupling part.

The connecting section preferably protrudes beyond the stator.

Preferably, the stator includes a stator body and a shell. The casing preferably at least partially encloses the stator body.

Provision can be made for the at least one opening to be formed in the stator body and in the casing.

The stator may include a stator insert. The stator insert element preferably at least partially includes the aforementioned blocking element recess.

The stator insert element is preferably inserted into the stator body. It may be that the stator insert element is covered by the shell from the outside. This achieves a simple assembly.

In particular, the blocking element recess can include a contact surface. The contact surface and the blocking element are preferably designed in relation to one another in such a way that the blocking element is spaced apart from the blocking element by contact with the contact surface. The distance enables the blocking element to operate almost without wear and damage over time. In addition or as an alternative, it can be provided that the blocking element remains in the first position as a result of the contact with the contact surface.

Provision can be made for the stator insert element to encompass the contact surface.

It may be that the stator comprises a stator element which has a further contact surface for the blocking element in order to move the blocking element from the first position into the second position.

The stator element is preferably movably mounted in the rest of the stator.

In particular, the stator comprises an annular projection which is accommodated in the rotor and/or protrudes into the keyway. The projection is interrupted in at least one section by a gap in order to interact with a key like a bayonet 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 the second protective element part are preferably designed separately from one another. The first and second protective element parts are preferably urged towards one another by a spring device.

The spring device is designed in particular as a leaf spring, which is adapted to the contour of the protective element parts. The leaf spring sits with particular advantage on the outer surface of the first and second protective element parts and presses them together so that the spring device is designed like a clasp.

In particular, the spring device compresses the gap to a certain extent in the direction of a smaller gap dimension. Due to the design as a leaf spring, the spring device is designed to be particularly space-saving. For example, the spring device can be curved, in particular in the form of an open ring.

The protective element parts can be clamped to the rotor by the spring device. This results in a simple assembly.

The installation device preferably comprises an extension element. The extension element is designed to move axially to a rotor axis of the rotor in a first direction when a key is inserted and to move axially to the rotor axis in a second direction opposite to the first direction when the key is removed. This allows certain actions to be carried out by the built-in device simply by inserting the key. The extension element thus extends the effective range of the key. The key channel can thus be made particularly short.

In this case, the extension element can be moved, in particular linearly, between an insertion position and a withdrawal position in the axial direction.

Alternatively, when the extension member moves linearly, the extension member may be referred to as a pusher.

The extension element is preferably moved from the withdrawal position to the insertion position when a key is inserted and/or is moved from the insertion position to the withdrawal position when a key is withdrawn.

Because this task is performed by the extension element as part of the locking device, it is possible to better protect the interior of the locking device against manipulation. In this case, the blocking device can comprise at least one wall, behind which the extension element is at least partially arranged. "Behind" here is to be understood from the point of view of the user operating the locking device. The pushed-in position is a position in which the extension element is further away from the user than in the withdrawn position. Here, the wall can delimit a key channel to the rear.

The extension element preferably traverses the substantial length along the rotor axis of the closure device and is accommodated so as to be axially movable with respect to the rotor axis.

The extension member is located inside the locking device where the locking mechanism is located. Thus, the control device, the actuator, the blocking element and/or the blocking element is protected from manipulation in particular by the wall.

Provision is preferably made for each insertion movement of a key into an end position to act on the extension element. In particular, each insertion movement is effective of the key to an end position on the extension element in such a way that the extension element is moved from the withdrawal position into the insertion position.

Provision can be made for the blocking device to include an energy accumulator, in particular a spring, in order to urge the extension element into the withdrawal position. Preferably, the extension element comprises an engagement element for engagement with the key. This makes it possible for the extension element to always be moved from the insertion position into the withdrawal position when the key is withdrawn.

The extension element is preferably designed to move the coupling part.

The extension element is in particular designed to be movable independently of the coupling part. Independent means here that a movement of the extension element cannot be transferred to the coupling part via a connection with the coupling part. The independent movement of the extension member from the coupling part, however, involves the coupling part following a movement of the extension member, for example because the coupling part is biased towards the extension member by a spring.

In particular, the extension element is designed in the axial direction without a form fit to the coupling part.

The coupling part can preferably be arranged outside the stator, in particular in the guide of the rotor.

It can be provided that the coupling part remains in a coupling position during a movement of the extension element in the second direction. In the coupling position, the coupling part is in operative connection with the driver. In a decoupling position, the coupling part is out of operative connection with the driver. Due to the fact that the coupling part remains in the coupling position during a movement of the extension element into the withdrawal position, an operative connection remains between the rotor and the driver after the key has been withdrawn. Because the blocking element also blocks movement of the rotor after the key has been removed, movement of the driver is blocked at the same time by the blocking element. As a result, the driver is protected against manipulation. The coupling part can include a coupling element. The coupling element can establish the operative connection between the rotor and the driver. The coupling element can in particular be guided in the guide of the rotor. When the extension element moves into the withdrawal position, the coupling element preferably remains in the coupling position, ie in operative connection with the driver. The coupling element thus ensures that the coupling position is maintained. The extension element can preferably be moved independently of the coupling element.

Preferably, the built-in device includes a front side that faces outwards when installed. When the installation device is in the installed state, the blocking element is arranged between the front side and the coupling part. In addition, the blocking element is arranged between the front side and the guide for the coupling part.

Provision can be made for the actuator to be arranged between the front side and the guide for the coupling part when the installation device is in the installed state.

Provision is preferably made for each insertion movement of the key into an end position to act on the extension element.

Provision can be made for the extension element to act on the coupling part without an interposed force accumulator. An energy accumulator, in particular a spring, can be provided in order to urge the extension element in the second direction. However, the energy accumulator does not serve to charge itself if the extension element and the coupling part have different possibilities of movement, for example if the coupling part cannot be operatively connected to the driver due to a current spatial arrangement.

The coupling part is preferably designed in several parts with a spring. Mechanical energy can be stored by means of the spring in the case of a momentary spatial arrangement of the clutch part in relation to the driver, which prevents engagement. If the spatial arrangement of the clutch part in relation to the driver permits engagement, then the clutch part engages by means of the spring force of the spring of the clutch part.

It is preferably provided that a 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 to be filigree and to save installation space.

The extension element can be designed to interact with the coupling part in the direction of rotation without a form fit. This prevents the extension element from transmitting the torque to the coupling part.

The extension element can be designed to interact with the coupling part without a form fit.

The extension element is preferably designed in one piece.

The extension element is preferably angled. It can be provided that a first part of the extension element, which is intended to interact with the key, extends radially further outwards than a second part of the extension element, which is intended to interact with the coupling part. The advantage is that the second part more runs in the middle in order to be able to push the coupling part better. This keeps the dimensions of the coupling part in particular small.

Preferably, the stator includes a base which is designed to be directed inwards and/or towards the aforesaid driver of the locking device in the installed state. The base is preferably designed to face away from a keyway or knob and/or from the front.

The rotor preferably includes a projection that abuts the base. In particular, the projection is formed integrally with a connecting portion. Additionally or alternatively, the projection can be formed in one piece with a guide for the blocking element. Additionally or alternatively, the projection can be designed in one piece with an installation space for the blocking element, for the actuator and/or for the control device. Additionally or alternatively, the projection can be formed in one piece with an installation space for the actuator assembly.

The rotor can be divided into a first section and a second section. A first section can be directed towards the front side and a second section can be directed towards the base side.

It can be provided that sections of the rotor have different diameters. The first section of the rotor can preferably have a larger diameter than a second section of the rotor.

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

Provision can be made for the first section to be made from a different material, in particular from a harder and/or stronger material, than the second section. In particular, the first section can be made of a ceramic material and/or can serve as a protection against drilling.

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

The second section preferably accommodates the blocking element.

The blocking element is preferably mounted in the second section.

Preferably, where the stator surrounds the second portion, the at least one opening, preferably the plurality of openings, is located for the fastener.

In particular, the first section accommodates the transmission device and/or the key channel.

Provision is preferably made for the extension element to extend from the first section to the second section.

The rotor may include a first rotor element and a second rotor element. The first rotor element and the second rotor element are preferably connected to one another in a reversibly detachable manner. The first rotor element may include the first section. The second rotor element may include the second section.

It can be provided that the first rotor element comprises an end surface facing towards the second rotor element. The axial position relative to the stator can preferably be fixed in one spatial direction by the end face.

It can be provided that the second rotor element includes the projection for abutment on the base.

Due to the projection of the second rotor element and an axial attachment of the first rotor element, for example the end surface of the first rotor element or a snap ring, it is possible to insert the first rotor part from the front side and the second rotor part from the base side into the stator, in particular into the stator body to stick. If the first and the second rotor part are connected to one another, the rotor is fixed axially to the rotor axis.

In particular, the rotor elements can be connected to one another in a reversibly detachable manner. The reversibly detachable connection can be produced by means of a form fit and/or force fit. The reversible detachability can be provided in particular in the direction of rotation, preferably also in the axial direction. i.e. a defective rotor element can be replaced.

Provision can be made for the first rotor element to comprise a first fastening means and the second rotor element to comprise a second fastening means, with the rotor elements being fastened to one another in a form-fitting and/or force-fitting manner, preferably in a form-fitting manner, by the first and second fastening means in the direction of rotation.

Provision can be made for the first and the second rotor element to be connected to one another at least indirectly in the axial direction by a positive and/or non-positive connection, preferably a positive connection, for example a latching connection. The locking device can include a latching device, the first rotor element and the second rotor element being connected to one another via the latching device. The latching device can provide the latching connection. For example, both the first rotor element and the second rotor element are clipped with the latching device.

The invention also provides a lock cylinder-like locking device with an inserted installation device according to the invention. The installation device can be designed as described within the scope of this disclosure.

The locking device preferably comprises a fastening element which is inserted from the outside through a recess in the locking device into the locking device housing in order to fasten 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.

The locking device housing is preferably designed without the blocking element recess.

The locking device can include the coupling part. The coupling part is preferably designed in several parts. The coupling part can comprise a sliding element. The sliding element is actuated by the extension element. The coupling part can include the coupling element. The coupling element preferably establishes the operative connection to the driver. The coupling part can comprise a spring, the spring being arranged between the sliding element and the coupling element. 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 element. This can occur in a spatial arrangement in which the coupling element cannot be brought into operative connection with the driver. This makes it possible for every movement of the key to act on the extension element and/or for the extension element to be designed in one piece.

The locking device can include the driver.

Finally, the invention provides a locking device system with a plurality of locking devices according to the invention. The locking devices can be designed as described within the scope of this disclosure. Their installation devices are advantageously constructed identically in each case. In particular, the locking devices comprise locking device housings that are different from one another. For example, a locking device can be designed as a double cylinder and a further locking device can be designed as a half cylinder. In another example, one locking device can be designed as a double cylinder and another locking device can be designed as a furniture cylinder or as a padlock.

The built-in device is preferably free of mechanical coding. i.e. the locking authorization results exclusively from the electronic data that are sent and/or received by the built-in device by means of the transmission device. This makes it possible, in particular, to construct the built-in devices identically.

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

An installation device 1 according to a first exemplary embodiment of the invention is inserted in the right half of the housing 101 here.

According to the invention, the installation device 1 has 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 closure element. Thus, on the one hand, a locking device housing 101, which is adapted to the locking element, is provided and, on the other hand, a generic installation device that can be used in different locking device housings 101. In this case, the installation device 1 comprises those elements which are necessary for blocking a movement of the driver 103 and for releasing the movement of the driver 103 .

In this way, a locking device system according to the invention that is easy to produce and has a plurality of locking devices 100 can also be made available. In this case, installation devices 1 according to the invention are used in at least two of the following different locking device housings: in a locking device housing 101 of a double cylinder with a first length, in a locking device housing 101 of a double cylinder with a second length, in a locking device housing of a half cylinder, in a locking device housing of a furniture lock, in a Locking device housing of a padlock. The driver 103 can, for. B, in the case of a furniture lock themselves act as a bolt.

For this purpose, the installation device 1 comprises the stator 10 arranged on the outer circumference, in which a rotor 30 of the installation device 1 is inserted so that it can rotate about a rotor axis 35 which, for example, coincides with the axis of rotation of the driver 103 . On its front side 37 facing away from the driver 103, the rotor 30 comprises a key channel 36 for inserting a shank of a key 200. The key 200 carries an electronic locking secret in the form of electronic data. The authorization of a user to unlock the door can be determined on the basis of the locking code.

The key 200 is preferably designed without mechanical coding. Accordingly, the installation device 1 according to the invention is designed without a mechanically coded tumbler. Thus, it can only be determined on the basis of the electronic locking code whether the user has authorization or not. In this case, the key 200 and the installation devices 1 can be mechanically identical to one another. This increases the generic application possibilities of the built-in device 1.

2 Figure 12 shows the closure device 100 partially disassembled. The housing 101 has, for example in both halves of the recess for the driver 103, openings 104 in the lower area, of which the opening on the right is provided with a reference number. The openings 104 here extend perpendicularly to the axis of rotation of the driver 103. The openings 104 serve to fasten the built-in element 1 in the locking device housing 101 by means of a fastening element 102.

The driver 103 has, for example, an internal contour that is non-circular in cross section, for example in the form of an internal tooth system, in which an insert 105 preferably engages in a form-fitting manner. For this purpose, the insert 105 has an outer contour that is preferably designed to complement the inner contour of the driver 103, here in the form of external teeth, so that the two parts 103, 105 are arranged in a rotationally fixed manner with respect to one another.

A connecting section 38 of the installation device 1 protrudes into the insert 105 . A coupling part 41 is slidably arranged in a guide 42 in the connecting section 38 . The coupling part 41 is designed in several parts. Depending on the position of the coupling part 41 , the coupling part 41 can establish or release an operative connection between the rotor 30 and the driver 103 , in particular via the insert 105 . For this purpose, the coupling part 41 of the locking device 100 can engage in a non-illustrated inner contour of the insert 105 in a form-fitting manner. The guide 42 preferably forms a linear guide for the coupling part 41, so that the coupling part 41 is arranged to be guided along the rotor axis 35 of the rotor 30 so that it can be moved. In an engaged state, the coupling part 41 is both in the guide 42 and in operative connection with the driver 103, the coupling part 41 being slightly disengaged. In the disengaged state, the coupling part 41 is set back in the guide 42, so that the operative connection with the driver 103 is eliminated.

The installation device 1 is designed in particular 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 . As a result, different functions can be achieved in the locking device. The guide 42 is arranged outside of the stator 10 so that different coupling parts 41 can be used easily.

If the installation device 1 is to be rigidly connected to the driver 103, this can also be carried out using the guide 42. Here, a connecting element (not shown) can be inserted into the guide 42, which establishes the rigid connection to the driver. It is also possible to use a cam in the guide 42, which always rotates with the rotor 30, but takes the driver 103 with it only in a predetermined angular range.

The installation device 1 has a cover 14 with which the installation device 1 is pushed into an associated insertion opening 106 of the housing 101 . Fastening element 102, here in the form of a screw, for example, is screwed in through recess 104 on the right here from the underside of housing 101 and through an opening 21 on the left here in casing 14 of stator 10 and a stator body 11 of stator 10, which is explained in more detail later. The fastening element 102 thus fixes the stator 10 in the housing 101. Furthermore here the key channel 36 for inserting the key 200 is designated, which is formed in a first rotor element 32 of the rotor 30 .

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

The opening 21 is provided in a part of the stator body 11 that has a thicker wall than another part of the stator body 11 . In this case, the opening 21 is formed in the part of the stator 10 with the greater wall thickness, so that the built-in element 1 is securely fastened in the locking device housing 101 . A plurality of openings 21 are preferably provided in order to fasten the built-in device 1 in different locking device housings 101 and/or with different fastening elements 102 (see Fig. 2 and 8th ).

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

3 shows that the stator 10 is cylindrical. The casing 14, not shown, is here adapted to the contour of the stator body 11 (see also figure 8 ). This makes it particularly easier to use the stator 10 in different locking device housings 101 that are easy to manufacture.

In 3 the installation device 1 is shown without the cover 14 and the coupling part 41 . 4 shows the installation device 1 without the casing 14 and without the stator body 11 in the partially dismantled state.

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.

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 Fig. 4 ) fixed axially towards the driver 103 in the direction of the arrow 79 . In this case, the end surface 66 is in contact with an inner structure of the stator 10 , in particular of the stator body 11 .

A circumferential projection 43 (see Fig. 4 ) of the second rotor element 33, here as a collar, serves as a stop for the second rotor element 33 on the stator 10. The second rotor element 33 can be inserted from a base 23 of the stator 10 until the projection 43 rests against the base 23. The projection 43 is preferably formed in one piece with the second rotor element 33 . Due to the one-piece design, the second rotor element 33 can only be inserted into the stator 10 from the base 23 .

The insertion of the rotor 30 or the rotor element 33 from the base 23 is particularly favored by the subdivision into the insert element 1 and the locking device housing 101 .

Due to the fact that the projection 43 rests against the base side 23, the second rotor element 33 is fixed axially towards the front side 37 against the direction of the arrow 79. The second rotor element 33 is inserted into the stator 10 from a base side 23 of the stator 10 during assembly without the first rotor element 32 . The use of the projection 43 allows additional installation space in the rotor 30.

The first and second rotor elements 32, 33 are connected to one another in a rotationally fixed manner after insertion, in particular in a reversibly detachable manner. Due to the division into rotor elements 32, 33, assembly of the rotor 30 is particularly easy to accomplish. By linking the two rotor elements 32, 33, the resulting rotor 30 can be tilted forwards and backwards, i. H. with and against the direction of the arrow 79, fixed axially.

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

The rotor elements 32, 33 can be made of mutually 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 useful because the first rotor element 32 is designed to hold the key 200 and is therefore exposed to greater mechanical loads than the second rotor element 33. Drill protection can also be implemented in this way in a simple manner. For example, the first rotor element 32 can be made of a ceramic material.

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

The stator body 11 is designed like a sleeve. 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 that surrounds the second rotor element 33 is designed with a greater wall thickness than that part of the stator body that surrounds the first rotor element 32. As a result, 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.

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

A blocking element 31 is mounted in the rotor 30, in particular in the second rotor element 33, preferably perpendicularly to the rotor axis 35, towards the blocking element 51 and away from it so that it can be moved linearly. in a figure 5 In the first position shown, the blocking element 31 is in a blocking element recess 15 (see Fig. figure 5 ), which is formed by a stator insert element 13 and stator elements 12. As a result, the rotor 30 and thus the coupling part 41 are prevented from being rotated relative to the stator 10 . The turning of the inserted key 200 to unlock the associated lock is blocked or prevented. In a second position of the blocking element 31 (not shown), the blocking element 31 is disengaged from the blocking element recess 15 of the stator 10. This makes it possible to rotate the rotor 30 in the stator 10 and thus the driver 103.

The locking element recess 15 is outward, i. H. to the locking device housing 101, formed closed. Thus, the blocking element 31 is in the first position and in the second position completely within the installation device 1. It is therefore not necessary to make a blocking element recess in the locking device housing 101. In the exemplary embodiments presented here, the blocking element recess 15 is outwardly delimited at least by the casing 14, preferably also by the stator insert element 13.

The blocking 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 connected to the guide 81 and the installation space 82 in one piece.

The blocking element 31 is urged into the first position by at least one spring 34, preferably a plurality of springs 34. In the embodiment of figure 5 several springs 34 are provided. The stator, in particular the stator elements 12 and/or the stator insert element 13, limit the movement of the blocking element 31 against the direction of the arrow 70. The blocking element 31 remains in the installation space delimited by the casing 14. Thus, it is not necessary to provide a locking member recess in the buckle housing 101 .

The stator elements 12 and the stator insert element 13 are arranged in the portion of the stator 10 which surrounds the second rotor element 33 . The small diameter of the second rotor element 33 makes it possible to provide the movable stator elements 12 in the stator 10 .

The blocking element 51 is between a release position in which the cutout 54 is opposite the blocking element 31 so that the blocking element 31 moves into the cutout 54 and locking positions in which the recess 54 does not oppose the locking member 31 so that the locking member 31 is prevented from entering the recess 54, rotatably. In the figures 4 and 5 Blocking positions of the blocking element 51 are shown.

The blocking element 31 is designed on its contact section 63 facing the blocking element 51 so that it can move into the recess 54 when the blocking element 51 is in the release position and the recess 54 is opposite the contact section 63 of the blocking element 31, in figure 5 i.e. pointing upwards. This makes it possible for the blocking element 31 to reach the second position.

A first contact surface 16 of the stator elements 12 facing the blocking element 31 is designed to push the blocking element 31 in the direction of the blocking element 51, i.e. into the second position, when the rotor 30 rotates, in which the rotor 30 can rotate freely relative to the stator 10. The first contact surface 16 is designed as an inclined surface that pushes the blocking element 31 into the second position.

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 urged 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 according to the direction of movement 71 is perpendicular to the direction of movement 70 of the blocking element 31.

When the rotor 30 is unlocked relative to the stator 10, the locking element 31 is initially located in the locking element recess 15. The locking element 31 is guided in the second rotor element 33 in this case. In addition, the blocking element 31 is in contact with 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 blocking element 31 . The blocking element 31 is centered by the contact with the contact surfaces 16 . This position of the blocking element 31 is referred to as the rest position. In the rest position, the blocking element 31 is preferably arranged at a distance from the blocking element 51 .

A user now wants to unlock the door and inserts the key 200 into the key channel 36. This starts electronic communication of the key with the control device 53, in which it is determined electronically whether the user is authorized.

If the user is authorized to unlock the door, the control device 53 controls the actuator 52 . The actuator 52 designed as an electric motor rotates the blocking element 51 into the release position in which the recess 54 is opposite the blocking element 31 . If the rotor 30 is now started to rotate using the key 200, the blocking element 31 slides along one of the first contact surfaces 16 into the second position, in which the blocking element 31 engages in the recess 54. Here, the springs 34 are stretched. The blocking element 31 moves in the direction of movement 70.

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

The rotor 30 is now freely rotatable. The locking element 31 slides along that of the first contact surfaces 16 into which the locking element 31 is rotated. The locking element 31 is surrounded by the first contact surfaces 16 in both directions of rotation, so that rotation in both directions when it contacts one of the first contact surfaces 16 allows the locking element 31 to move into the second position. So that there are first contact surfaces 16 in both directions of rotation, the blocking element recess 15 is surrounded on both sides by stator elements 12 .

The stator 10 has second contact surfaces 17, which the blocking element 31 leaves in the first position. The second contact surfaces 17 are functionally used when the user is not authorized to unlock the door. The second contact surfaces 17 are formed in the stator insert element 13 . If the blocking element 31 is in the rest position, the second contact surfaces 17 are spaced further away from the blocking element 31 than the first contact surfaces 16.

The second contact surfaces 17 are preferably also inclined, but in the opposite direction to the first contact surfaces 16 in relation to the direction of movement 70 of the blocking element 31.

At its end facing the stator insert element 13, the blocking element 31, seen along the axis of rotation of the blocking element 51 and/or the rotor axis 35, has a cross section which has the shape of a preferably symmetrical trapezium tapering in the direction of the blocking element 51. The legs of this trapezoid form head surfaces 60 outwardly in relation to the blocking element 31. The head surface 60 and the corresponding contact surface 17 are designed to be inclined relative to the direction of movement of the blocking element 31.

If the user is not authorized to unlock the door, the sequence is as follows. The locking element 31 is initially in the rest position. A key 200 without a locking authorization is inserted into the keyway 36 . The electronic data exchange shows 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 does not oppose the blocking element 31, as in FIG figure 4 and 5 shown. Rather, an outer circumference of the blocking element 51 lies opposite the blocking element 31 .

If the rotor 30 is rotated, the blocking element 31 tries to slide along the first contact surface 16 . However, this is not possible because the blocking element 31 is on an outer circumference of the blocking element 31 stands up. Thus, the blocking element 31 cannot be pushed into the second position against the force of the springs 34 .

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

Here, the head surface 60 of the blocking element 31 comes into contact with the corresponding second contact surface 17 opposite one of the legs of the trapezoid.

In this state, the stator element 12 or the stator elements 12 have been moved back in the direction of rotation against the force of a spring element 18 . The spring element 18 presses the stator element 12 against the locking element 31 as the rotor 30 rotates further.

The contact surface 17 is designed in such a way that the contact surface 17 holds the blocking element 31 in the first position. Thus, the rotor 30 remains blocked by the blocking element 31 so that the door cannot be unlocked.

Every second contact surface 17 corresponds to a respective head surface 60 of the blocking element 31 facing the head surface 60. The surface 60 and the corresponding contact surface 17 are designed in such a way that the contact surface 17 is located between the surface 60 and the blocking element 51 when the blocking element 31 is on the contact surface 17 is applied.

If an attempt is made to turn the rotor 30 further, the blocking element 31 slides away from the blocking element 51 counter to the direction of movement 70 . This is achieved by the slope of the second contact surface 17. The blocking element 31 can slide along with the head surface 60 on the second contact surface 17 . The blocking element 31 and the blocking element 51 can thus be spaced apart from one another when they are in contact with the second contact surface 17 . Additionally or alternatively, the forces that act on the blocking element 31 in the event of further attempted rotation of the rotor 30 are diverted into the second contact surface 17 . A contributing factor here is that the head surfaces 60 correspond to the second contact surfaces and the blocking element 31 thus lies flat against the second contact surface.

In figure 5 the blocking element recess is provided with the reference number 15 . 6 shows the arrangement of figure 5 Seen from an end face of the blocking element 31, only without blocking element 51. Here, the stator elements 12 are in the second position.

The blocking element 31 is surrounded by the second contact surfaces 17 in both directions of rotation, so that the rotation in both directions of rotation when it rests on one of the second contact surfaces 16 leaves the blocking element 31 in the first position.

In the first position of the stator elements 12, the first contact surfaces 16 are closer to the blocking element 31 than the second contact surfaces 17. In the second position of the stator elements, the second contact surfaces 17 protrude more into the blocking element recess 15 than the first contact surfaces 16.

The blocking element 31 is formed in one piece. As a result, first contact sections 64 of the blocking element 31, which are used to contact the first contact surfaces 16, are rigidly connected to the head surfaces 60, which are used to contact the second contact surfaces 17. The top surfaces 60 serve here as second contact sections. The first and the second abutment sections 60, 64 are rigidly connected to the third abutment section 63 of the locking element, which serves to abut in the recess 54.

The stator elements 12 and the stator insert element 13 are arranged in the portion of the stator 10 which surrounds the second rotor element 33 . Due to the small diameter of the second rotor element 33, it is possible to provide the first and the second system sections 16, 17 in the stator 10.

Because the stator comprises a stator body 11 and the stator insert element 13, assembly of the built-in element 1 is facilitated. The shell 14 serves to fasten 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 shell 14 covers the stator insert element 13.

figure 5 shows selected elements of the built-in device 1 4 . while showing figure 5 the arrangement of the blocking element 31 in relation to the blocking element 51 and the stator insert element 13 together with the stator elements 12.

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

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

The keyway 36 is provided in the first rotor member 32 . The key channel 36 thus ends in front of the actuator 52. The key channel 36 ends in front of the control device 53. This increases the security against manipulation.

An extension element 40 is intended to mechanically interact with the key 200 . If the key 200 is pushed into the key channel 36, upon contact it moves the extension element 40 axially or parallel to the rotor axis 35 into a pushed-in position.

The extension part 40 preferably moves the coupling part 41 away from the rotor 30 in the direction of the driver 103, so that the coupling part 41 can engage the driver 103 in rotation. A passage 39 is provided in the connecting portion 38 for the extension member 40 to abut against the coupling member 41 . Here, either the extension element 40 or the coupling part 41 can protrude through the passage 39 .

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 removal position. The extension element 40 is pushed into the withdrawal position by a force accumulator 49 .

The extension element 40 extends from the first rotor element 32 to the second rotor element 33. As a result, the extension element bridges a distance between the inserted key 200 and/or the key channel 36 and the coupling part 41. The effective space of the key 200 is thereby extended.

The first rotor element 32 surrounds the extension element 40 radially.

The second rotor element 33 includes a guide 65 for axially guiding the extension element 40 between the withdrawn position and the inserted position.

The extension element 40 is angled in the example shown. A first part of the extension element 40, which is intended to interact with the key 200, runs radially further outward than a second part of the extension element 40, which is intended to interact with the coupling part 41. As a result, the second part can be arranged more centrally in order to be able to push the coupling part 41 better.

The extension element 40 is designed to push the coupling part 41 but without being positively engaged with the coupling part 41 . The extension element 40 can thus be moved independently of the coupling part 41 . Rather, when the key is removed, the coupling part 41 initially remains engaged.

This allows the extension element to be of filigree design.

Torque is transmitted from the key 200 to the rotor 30 to the clutch member 41 . In this case, no torque is transmitted via the extension element 40 . Rather, the torque from the first rotor element 32 to the second Rotor element 33, whose leadership 42 is transferred to the coupling part 41. The torque is transmitted from the coupling part 41 to the driver 103 via the insert 105 .

The extension element 40 serves to return the blocking element 51 mechanically and/or magnetically from the release position to the blocking position. Here, the extension element 40 can be moved back into the withdrawal position when the key is withdrawn. When the extension element is moved into the withdrawal position, a movement of the blocking element 51 into the blocking position can be caused or permitted. For example, in relation to the second embodiment in figure 7 shown spring are stretched during the movement of the blocking element 51 in the release position. When the key is inserted in the inserted position, the extension element 40 holds the blocking element 51 in the release position and allows the blocking element 51 to move back into the blocking position if the extension element 40 with the key 200 moves in the direction of the front side 37 when the key is removed.

A latching element 61 is provided which holds the rotor 30 in position with respect to the stator 10 .

The latching element 61 is formed, for example, by means of a spring-loaded latching lug. i.e. the rotor 30 can overcome the detent 61 when rotating, so that the function of the rotor 30 is maintained. Here, the detent 61 gives haptic feedback to the user that a desired position has been reached. The locking element 61 is arranged to be axially movable. The axial mobility of the latching element 61 is made possible by the different diameters of the rotor elements 32, 33.

The latching element 61 is movably mounted in an opening (not shown) in the stator 10 , in particular in the stator body 11 . The opening is open to the outside, so that the sleeve 14 limits the mobility of the latching element 61 to the outside. The opening is partially closed towards the inside, so that the latching element 61 is guided in the stator body 11 , but partially opened axially and/or towards the inside, so that the latching element 61 can engage in the rotor 30 .

Furthermore, the detent 61 determines a position in which the key 200 can be inserted and removed. In this position, the locking element 31 is in the rest position at a distance from the blocking element 51 so that the actuator 52 can rotate the blocking element 51 .

The latching element 61 is provided on the first rotor element 32 .

The locking element 61 can be moved axially. This is made possible due to the different diameters of the first and second rotor elements 32, 33.

An annular projection 22 is formed by means of, in particular, half-shell-like parts whose inner surfaces 26 facing one another have a bayonet-type catch with the key 200 work together. The parts are inserted into a peripheral groove 45 of the first rotor element 32 . Outwardly protruding projections 25 of the annular projection 22 fix the parts of the projection 22 in the stator body 11 in their position relative to one another and to the stator body 11. The annular projection 22 acts with the inserted key 200, preferably like a bayonet, as a key removal lock.

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 have a rectangular ring cross-section. On the outer peripheral 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.

The Figures 7 to 9 12 show a further exemplary embodiment of an installation device 1 designed as an installation device. Unless described below, the second exemplary embodiment corresponds to the first exemplary embodiment.

figure 7 shows the installation device 1 without the casing 14 and the stator body 11 in the partially dismantled state. 8 shows a sectional view.

Instead of the screw 24, the first rotor element 32 comprises fastening means 67 and the second rotor element 33 has fastening means 68 corresponding thereto, which interlock positively so that the first rotor element 32 and the second rotor element 33 are fastened to one another in a torque-proof manner. Here, the first and the second fastening means 67, 68 are designed as projections and corresponding recesses.

Instead of the coil as the transmission device 44 , contact elements are provided, which transmit data and/or electrical energy to the installation device 1 via electrical contact with the key 200 . The contact elements 44 are attached to a housing 46 in a resilient manner.

The housing 46 also serves to fasten the rotor elements 32, 33 to one another axially. Thus, the housing 46 serves as a latching device. For this purpose, the housing 46 includes a first latching element 47 which latches into the first rotor element 32 . For this purpose, the first rotor element 32 has an edge 78 . The housing 46 has a second latching element 48 which latches into the second rotor element 33 . For this purpose, the second rotor element 33 includes a groove 77.

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

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

As in the first exemplary embodiment, the extension element 40 is moved into the withdrawal position by the spring 49 . In addition, the extension element 40 comprises a resilient engagement element 74. The engagement element 74 is intended for engagement with the key 200. FIG. The engagement of the engagement element 74 in the key 200 allows the extension element 40 to be moved from the insertion position to the extraction position when the key is withdrawn, e.g. if movement by the spring 49 has been prevented by manipulation.

The engagement of the engagement element 74 takes place in that the engagement element 74 in the pushed-in position on an inner side 75 of the stator body 11, which the second rotor element 33 bears against the resilient action of the engagement element 74 and is urged to engage in the key 200. In the trigger position, the in figure 8 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 as a result of the resilient force and/or chamfers.

The cavity 76 transitions into the keyway 36 .

figure 9 shows the second rotor element 33. Here, a groove 77, which is designed to engage with the latching element 48, is shown. The groove 77 also serves as a predetermined breaking point. In the event of an attempt at manipulation, the second rotor element 33 breaks apart at the groove 77 , with the essential part of the second rotor element 33 with the control device 53 and the actuator group 50 remaining in the stator 10 .

In the second embodiment of the Figures 7 to 9 a spring device 88 is provided. The spring device 88 is designed as a leaf spring which is 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 projection 22 is clamped to the first rotor element 32 in a manner similar to a snap ring by the spring device 88 . However, the rotor 30 can be rotated without the projection 22 rotating together with the spring device 88 , so that the projection 22 is fastened in the stator 10 in a rotationally fixed manner during a rotation of the key 200 .

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

As in figure 10 shown, the coupling part 41 is designed in several 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.

The slide member 91 is slid by the extension member 40 when the extension member 40 slides from the withdrawal position to the insertion position. The coupling element 92 is intended to be guided in the guide 42 and to be operatively connected to the driver 103 in a coupling position. If the sliding element 91 is displaced when the key 200 is inserted and the insert 105 and the coupling element 92 are in a geometrically matching spatial position with respect to one another, the coupling element 92 is also displaced via the spring 93, so that the coupling element 92 moves into the coupling position , i.e. H. engages with the insert 105 and is thus in operative connection with the driver 103. If the sliding element 91 is displaced when the key 200 is inserted and the insert 105 and the coupling element 92 are in a spatial position that does not match one another geometrically, the spring 93 is tensioned and the coupling element 92 initially remains in an uncoupling position until the insert 105 and the coupling element 92 can assume a geometrically matching spatial position in relation to one another and the coupling element 92 reaches the coupling position as a result of the force of the spring 93 . The coupling element 92 is arranged in the guide 42 both in the coupling position and in the uncoupling position. In the uncoupled position, the coupling element 92 is further away from the driver 103 than in the coupled position.

In order to allow a small installation space for the locking device 1, it is provided here that the key 200 pushes the extension element 40 into the pushed-in position without an energy accumulator connected in between. The extension element 40 pushes the coupling part 41 without an interposed force accumulator. Rather, the energy accumulator in the form of the spring 93 is provided outside an interior space of the locking device 1 in the connecting section 38 .

The extension element 40 is designed to push the coupling part 41 but without being positively engaged with the coupling part 41 . For this purpose, the extension element comprises a section 86. The extension element 40 can thus be moved independently of the coupling part 41. Rather, when the key is removed, the coupling element 92 initially remains in the coupling position. In the trigger position, however, the extension member allows movement of the coupling member 92 to the uncoupled position. As a result, the driver 103 is connected to the stator 10 via the coupling element 92, the second rotor element 33 and the blocking element 31, so that the driver 103 cannot rotate when the key is removed. This provides good protection against manipulation.

A movement of the coupling element 92 in the uncoupling position can, for. B. via a pressure on another sliding element 94 done. The sliding element 94 can, for example 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 displaced. As a result, a further coupling element 95 is pushed into a coupling position with the driver 103 either directly or by tensioning a further spring 96 . At least when the key of the locking device 100 according to the invention is removed, the coupling element 92 is shifted from the coupling position into the uncoupling position.

In figure 11 Another exemplary embodiment of a coupling part 41 of a locking device 100 according to the invention is shown. For example, the coupling part 41 is the figure 11 used when a knob is used on the other side of the door. The knob is firmly connected to the driver 103. If the key 200 is withdrawn from the locking device 100 according to the invention and the extension element 40 is moved into the withdrawal position, the force of the spring 96 presses the coupling element 92 into the uncoupling position.

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

It is conceivable that the coupling part 41 is missing in the installation device 1 according to the invention. Rather, 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 serve as a bolt itself, z. B. in a furniture lock. The driver 103 and the insert 105 can be formed in one piece with each other.

The stator insert element 13 and the stator body 11 can be designed in one piece. It is also conceivable that the shell 14 is missing and the stator body is fastened directly in the closing device housing 101 .

It may be that the actuator moves the blocking element 51 back into the blocking position. This can be provided in particular for knob cylinders.

The blocking element 51 can alternatively be designed in the form of a plunger. In this case, a preferably bistable magnet can be used as an actuator. The plunger may be spring loaded in one direction, preferably away from the magnet.

Elements of the first embodiment can be implemented in the second embodiment and vice versa. For example, the second exemplary embodiment can comprise a coil as the transmission device 44 or the first exemplary embodiment can comprise contact elements as the transmission device 44 . For example, the rotor elements 32, 33 of the first embodiment may be fixed together as in the second embodiment. The extension member 40 of the first embodiment and the second Embodiment can be interchanged. The axial fixing of the first rotor element 32 with respect to the stator can take place in accordance with the first or second exemplary embodiment.

The installation device 1 according to the invention can be used in a switching element housing, not shown. In this way, a switching element is obtained which can only trigger a switching process if the user has electronic authorization. Here, a driver that rotates with the rotor 30 is used, which actuates a switch. Due to the installation device 1 according to the invention, it is not necessary to provide a blocking element recess in the switching element housing itself. Rather, the stator 10 and the switching element housing together form a fixed component.

The invention is not limited in its implementation to the preferred exemplary embodiment given above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different designs. All of the features and/or advantages resulting from the claims, the description or the drawings, including structural details or spatial arrangements, can be essential to the invention both on their own and in a wide variety of combinations.
