Description

The invention relates on the one hand to a locking device for a closure element or a switching element according to the preamble of claim 1. Such a locking device is provided with a stator, with a rotor having a rotor axis and with an electromechanical actuator in the rotor. The rotor has a first rotor element and a second rotor element, the first rotor element and the second rotor element being arranged axially one behind the other in relation to the rotor axis. The first rotor element and the second rotor element are connected to one another in a rotationally fixed manner. The electromechanical actuator is arranged in one of the rotor elements. Furthermore, the invention relates to a locking device equipped with such a locking device. Locking devices are available in numerous designs, for example in the form of a locking cylinder.

State of the art

The EP 1 914 368 B1 discloses a lock cylinder with a cylinder housing as a stator. The lock cylinder also includes a rotor in which an electric motor is arranged. The electric motor moves a blocking element, which can be brought into a release position and into a blocking position, as a result of which movement of the rotor relative to the stator is enabled or prevented. The rotor is designed as a monolithic component that can be inserted into the lock cylinder. The disadvantage here is that the rotor can hardly be reduced in size and/or adapted to special circumstances.

Disclosure of Invention

The object of the invention is therefore to reduce the size of the rotor of a generic locking device, in particular to create a locking device provided with such a locking device.

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 15. Advantageous developments of the locking device are specified in the description and in the figures. Features and details that are described in connection with the blocking device according to the invention also apply in connection with the locking device according to the invention and vice versa. The features mentioned in the description and in the claims can each be essential to the invention individually or in combination.

A locking device according to the invention for a closure element or for a switching element is provided with a stator, a rotor with a rotor axis and an electromechanical actuator in the rotor. The rotor has a first rotor element and a second rotor element. The first rotor element and the second rotor element are arranged axially one behind the other in relation to the rotor axis and are connected to one another in a torque-proof manner. The electromechanical actuator is arranged in one of the rotor elements.

The non-monolithic rotor elements are thus produced according to the invention as individual rotor elements prior to assembly. This makes it possible to optimize the rotor elements with regard to the elements to be accommodated or held. This also opens up the possibility of being able to produce necessary structures on or in the rotor elements more easily and/or more cost-effectively.

The rotor elements can be particularly well adapted for function and/or assembly. Due to the good adaptation, it is possible to optimize the size of the blocking device according to the invention or to adapt it to the circumstances. For example, one rotor element may require higher material strength than the other rotor element.

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 locking 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 blocking device serves to be used in a particular door-like closure 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 closure element. Preferably, the stator of the blocking device is at least indirectly non-rotatably connected to the closure element.

The locking device can have a driver or can be connected to a driver. Rotation of the ratchet rotor 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 blocking 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 z. B. cause the driver to assume an unlocked position.

In a preferred embodiment, the locking device is designed as a built-in device. The installation device is designed to be inserted into a locking device housing of a locking device. The built-in device is preferably fastened in a rotationally fixed manner in the locking device housing by means of a fastening element. Thus, in the assembled state of the locking device, the stator of the locking device and the locking device housing can form a common fixed unit.

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. In the event that the blocking device is designed as an installation device, the advantage of saving installation space by subdividing the rotor into a first and a second rotor element according to the invention is particularly great.

The locking 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. The locking device may include a keyway. A key can be inserted into the key channel.

If the blocking device is designed as a built-in device, it is preferably provided that the blocking device comprises a connecting section in order to be connected to a driver.

Alternatively, it can be provided that the locking device itself is designed as a lock cylinder, in particular as a double cylinder or half cylinder, as a knob cylinder, as a furniture cylinder or as a padlock. In this case, the stator also serves as a housing for insertion into or attachment to the closure element.

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

The electromechanical locking device includes the 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. For this purpose, a blockage can be canceled and/or a clutch can be adjusted.

For example, the locking device can include a locking element. In a first position, the blocking element prevents the rotor from being rotated with respect to the stator. In a second position, the locking member allows the rotor to rotate relative to the stator. The locking member is moveable between the first and second positions.

The blocking element can be movably mounted in the rotor. The rotor preferably includes a linear guide for the locking element. It can be provided that the stator includes a blocking element recess in which the blocking element engages in the first position. In the second position, the blocking element is disengaged from the blocking element recess.

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

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

The locking device may include a transmission device. The transmission device can be used as a transmitting and receiving unit, as a biometric sensor, as a keypad for

PIN input and / or be designed as a contact element for electrical contacting a particular 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 a user's authorization to unlock the spatial area or to actuate the switching element. 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 blocking device. The electrical energy can be provided for actuating the actuator and/or for the control device.

For example, the transmission device can be attached to the latching device. Preferably, the transmission device is resiliently attached to the latching device.

The locking device according to the invention preferably comprises a blocking element. The actuator assembly may include an actuator assembly having the actuator, the locking member, and the blocking member.

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 enables the blocking element to be moved 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 so that the recess is opposite the blocking element, so that the blocking element can move into the recess.

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.

Provision is preferably made for the first rotor element to be arranged in front of the second rotor element from the perspective of a user in a state in which the blocking element is installed in the closure element. From the user's point of view, the second rotor element is arranged behind the first rotor element. In other words, the first rotor member includes a front face that faces the user in a state where the locking member is installed in the shutter member. In other words, the second rotor element is located between the driver and the first rotor element and/or the second rotor element is designed to be arranged between the driver and the first rotor element.

The stator preferably has a base. The base is preferably designed to be directed inwards and/or towards a driver of the locking device or the locking device in the installed state. The base is preferably configured to face away from a keyway or knob.

The second rotor element and the base are preferably designed in such a way that the second rotor element can be inserted into the stator from the base. The second rotor element and the base are preferably designed in such a way that the second rotor element can only be inserted into the stator from the base.

In particular, the second rotor element can preferably be inserted into the stator from the base side without the first rotor element. Particularly preferably, the second rotor element can be inserted into the stator from the base side only without the first rotor element. The second rotor element is preferably assembled by simply pushing it in.

The second rotor element preferably includes a protrusion integrally formed with the remainder of the second rotor element. According to the invention, the projection fixes the axial position relative to the stator, in particular in one spatial direction, in particular in the direction of insertion. This is a particularly simple and space-saving method of assembling the second rotor element. The second rotor element is preferably designed without an in particular ring-shaped groove for receiving a retaining ring. Rather, the rotor element is fixed axially in at least one spatial direction by the one-piece projection.

Provision can be made for a section of the stator which surrounds the second rotor element to have a greater wall thickness than a section of the stator which surrounds the first rotor element. Alternatively or additionally, the first rotor element can have a larger diameter than the second rotor element.

This can make it possible for the stator to provide at least one functionality. For example, the locking element recess can be provided in the part of the stator surrounding the second rotor element.

The stator may include a stator member having a first abutment surface for moving the locking member from the first position to the second position.

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

Preferably, the stator element may be provided in the part of the stator surrounding the second rotor element.

It can be provided that the stator has a second contact surface for the blocking element. The second contact surface serves to leave the blocking element in the first position. The second contact surface can serve to space the blocking element away from the blocking element when it contacts the second contact surface. The second bearing surface can preferably be provided in the part of the stator surrounding the second rotor element.

The stator may include a stator insert. The stator insert element preferably comprises the second contact surface. Additionally or alternatively, the stator insert element can comprise a guide surface for the stator element.

If the first rotor element is designed with a larger diameter than the second rotor element, the first rotor element is enabled to have at least one special functionality. For example, the first rotor element can house the transmission device and/or the keyway.

In particular, it is provided that the stator compensates for a difference in the diameter of the first and the second rotor element. This makes it possible for the stator z. B. is cylindrical.

Alternatively or additionally, the first rotor element and/or the second rotor element is/are designed in a cylindrical manner. In particular, the second rotor element protrudes into the first rotor element. This creates a connection option at least for the transmission of a torque between the first and the second rotor element.

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 in at least one spatial direction, in particular in the insertion direction of the first rotor element, can preferably be fixed by the end face. i.e. the first rotor element is already positioned when it is inserted into the stator, which simplifies assembly.

Additionally or alternatively, the first rotor element is fixed axially in at least one direction, preferably in both axial directions, by a ring, for example a snap ring.

Provision is preferably made for the first rotor element to be made from a different material, in particular from a harder and/or stronger material, than the second rotor element. In particular, the first rotor element can be made of a ceramic material and/or can serve as a protection against drilling. This has the advantage that the rotor has optimal properties at the various points in the stator.

In the blocking device according to the invention, it can be provided that the first rotor element detaches from the second rotor element when or at a specific mechanical stress. This can be realized in that one of the rotor elements, in particular the second rotor element, includes a predetermined breaking point. This prevents higher damage in the event of a break-in. In addition, this increases burglary security, since a potential burglar can hardly gain access.

The second rotor element can be designed to be arranged between the aforementioned driver and the first rotor element in the installed state. The second rotor element may extend between the base of the stator and the first rotor element. In this case, the second rotor element protrudes in particular beyond the base.

The second rotor element preferably accommodates the electromechanical actuator and/or the control device for controlling the actuator. This allows these elements to be placed as far away from the outside as possible to increase security.

The second rotor element preferably accommodates the blocking element. Additionally or alternatively, the blocking element can be arranged in the second rotor element. An actuator group is particularly preferably arranged in the second rotor element, the actuator group comprising the blocking element, the blocking element and the actuator.

Alternatively or additionally, the locking device comprises a latching element for latching in at least one position of the rotor relative to the stator and/or an anti-removal element for preventing a key from being removed in at least one position of the rotor relative to the stator. The locking element or the anti-removal element is or are preferably arranged on the first rotor element and/or interact with the first rotor element.

The latching element can be arranged to be axially movable. This is made possible by the different radii of the rotor elements.

The installation device can also comprise at least one anti-drill rod which is arranged in the first rotor element and in the second rotor element.

The transmission device is preferably arranged in the first rotor element, with the first rotor element in particular radially surrounding the transmission device. As a result, the transmission device is protected, in particular with regard to assembly.

The locking device can comprise an extension element which is designed to move axially to the rotor axis 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. When the key is inserted, the extension element is in an insertion position. When a key is removed, the extension element is in a withdrawal position. The extension element can extend the radius of action of the key.

The extension element can in particular be linearly movable. In this case, the extension element can be called a slider.

For example, the key channel can be short. This is particularly conceivable if the locking device is designed without mechanical coding. For example, the key channel can essentially be limited to the first rotor element.

Alternatively or additionally, the blocking device can include the key channel, which accommodates a key when it is inserted. The electromechanical actuator is preferably behind the key channel. Additionally or alternatively, the electronic control device is behind the key channel. Additionally or alternatively, the blocking element and/or the blocking element lies behind the key channel. This increases safety and/or saves installation space.

It is conceivable that a wall delimits the key channel to the rear. "Back" is to be understood here from the point of view of the user who operates the locking device. The control device, the actuator, the blocking element and/or the blocking element are protected against manipulation by the wall.

For example, the locking device can form the wall.

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

The extension element can be used to couple a driver to the rotor. In particular, the extension element serves to couple a driver to the second rotor element. Here, the extension element can move a coupling part into a coupling position. The movement of the extension element for moving the coupling part into the coupling position preferably takes place when a key is inserted into the key channel of the locking device. Provision can be made for the coupling part to be in the coupling position when the extension element is in the inserted position.

It can be provided that the first rotor element surrounds the extension element radially. It can be provided that the second rotor element guides the extension element.

In particular when the blocking device is designed as a built-in device, the stator can comprise an opening which is designed to accommodate a fastening element, which is guided through the locking device housing, for fastening the stator to a housing of the locking device in a rotationally fixed manner. In this case, the opening is arranged in particular radially with respect to the second rotor element. Preferably, the opening is provided in the part of the stator surrounding the second rotor element. This enables the stator to be firmly fixed to the closure device.

A locking device according to the invention comprises a locking device housing and a locking device designed as a built-in device. The installation device is accommodated in the lock cylinder housing, with the locking device in particular comprising a fastening element, with the fastening element being inserted into the locking device housing from the outside in order to fasten the stator to the locking device housing in a rotationally fixed manner. The fastener can z. B. be designed as a screw or a pin.

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.

In the here right half of the housing 101 designed as a built-in locking device 1 is used according to a first embodiment of the invention. The installation device 1 comprises a 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, corresponds to 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 code 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 locking 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. Here, the key and the locking devices can be mechanically identical to each other.

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, in the lower area through openings 104, of which the right through opening with a Reference is provided. The through openings 104 here extend perpendicularly to the axis of rotation of the driver 103.

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.

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 . A fastening element 102 in the form of a screw is screwed through the through opening 104 on the right here from the underside of the housing 101 and into an opening 21 on the left here in the casing 14 of the stator 10 and a stator body 11 of the stator 10 which will be explained in more detail later. The screw 2 thus fixes the stator 10 in the housing 101. The key channel 36 for inserting the key 200, which is formed in a first rotor element 32 of the rotor 30, is also designated here.

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 according to the invention the rotor 30 comprises a first rotor element 32 and a second rotor element 33 . Here is in 3 the installation device 1 is shown without the cover 14 .

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 .

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 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.

Both rotor elements 32, 33 are reversibly detachable, for example by means of a screw 24, fastened to one another and arranged in the stator body 11 so as to be freely rotatable.

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.

The design of both the first rotor element 32 and the second rotor element 33 is adapted to their functions.

On the one hand, the opening 21 is provided in the part of the stator 10 which surrounds the second rotor element 33 . The opening 21 is formed in both the shell 14 and 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 . Several openings are preferably provided in order to fasten the installation device 1 in different locking device housings 101 (see Fig. 8 ).

The second rotor element 33 accommodates an actuator assembly 50. 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 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.

A blocking element 31 is mounted in the second rotor element 33, preferably perpendicularly to the rotor axis 35, towards and away from the blocking element 51 so that it can be moved. 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 second rotor element 33 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 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 elements 12 and the stator insert body 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 recess 54 faces the locking element 31 so that the locking element 31 can enter the recess 54 and blocking positions in which the recess 54 does not face the locking element 31 so that the locking element 31 is prevented is to move into the recess 54, rotatable. In the figures 4 and 5 Blocking positions of the blocking element 51 are shown.

The blocking element 31 is designed at its blocking element 51 facing contact portion 63 to be able to move into the recess 54 when the blocking element 51 in the Release position is located 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 linearly guided in the second rotor element 33. In addition, the blocking element 31 is in contact with the first contact surfaces 16 of the stator elements 12 . As a result, the blocking element 31 is centered. 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 in surrounded by the first contact surfaces 16 in both directions of rotation, so that the rotation in both directions when in contact with one of the first contact surfaces 16 can move the blocking element 31 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 does not succeed since the blocking element 31 stands on an outer circumference of the blocking element 31 . 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 trapezium.

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 present.

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 against one of the second contact surfaces 17 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 locking 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 body 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 a stator insert body 13, assembly of the built-in element 1 is facilitated. The shell 14 serves to fasten the stator insert body 13 in the stator body 11 . The stator body 11 has a stator recess 19 into which a stator insert element 13 is inserted.

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 . The effective range of the key 200 is thereby lengthened by the short key channel 36. If 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.

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 to allow the Extension element 40 comes into contact with the coupling part 41 . Here, either the extension element 40 or the coupling part 41 can protrude through the passage 39 .

When the key 200 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 urged by a spring 49 into the withdrawal position.

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 key 200 and the coupling part 41.

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 . This allows the extension element to be of filigree design.

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, a spring (not shown) can be tensioned during the movement of the blocking element 51 into the release position. When the key is inserted in the insertion 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. Here, a rotation of the rotor 30 is inhibited by the latching element 61 in the stator in such a way that the Locking element 31 can take the rest position. 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 latching element 61 is provided on the first rotor element 32 . 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.

An annular projection 22 is formed by means of, in particular, half-shell-like parts whose inner surfaces 26 facing one another interact with the key 200 in the manner of a bayonet catch. 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 Figures 7 to 9 12 show a further exemplary embodiment of a locking 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 rotationally fixed manner in the direction of rotation. 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 locking 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 (see Fig. 9 ).

The end face 66 is not in contact with an inner contour of the stator 10 but rather with an outer surface of the stator 10 . As a result, the first rotor element 32 is fixed in the direction of the arrow 79 . Additionally or alternatively, 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 into the withdrawal position when the key is withdrawn.

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 .

As in figure 7 shown, the key channel 36 ends with a wall 36a. As in figure 8 As shown, only a portion of the extension member 40 designed to interact with the key 200 protrudes into the keyway 36. The wall 36a is substantially closed except for a portion necessary for the extension member 40 to protrude into the keyway . Due to the fact that the extension element 40 has a filigree design, at least with the part of the extension element 40 that protrudes into the key channel 36, the wall 36a can close off the key channel 36 and the components located behind it, namely the blocking element 31, the blocking element 51, the actuator 52 and the control device 53, protect. The key channel 36 can be made correspondingly short.

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 .

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 one another.

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 .

In a further alternative of the invention, the locking device 1 is not designed as a built-in device 1 . Rather, the stator 10 is designed as a locking device housing 101 . The rotor 30 can thus be designed to be pushed directly into a lock cylinder housing 101 . The locking device housing 101 then takes over the function of the stator 10.

It may be that the actuator moves the blocking element 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 element 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 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.
