Description

field of technology

The invention relates to a lock with an actuating element which is arranged rotatably in a housing and which is coupled to a driven part which is rotatably mounted in the housing in order to transmit a rotation to the driven part only if locking is authorized, the driven part being able to rotate the actuating element between a blocked position and a release position displaceable closing element, for example a bolt or a closing element.

The invention also relates to a lock cylinder with a cylinder core which is rotationally coupled to a locking element when a key is inserted into a key channel of the cylinder core.

State of the art

the DE 11 2007 001 299 B4 describes a so-called cam lock for a door or cabinet. In a cavity of a housing there is an actuating element designed as a handle, which can be rotated to actuate a swivel bolt located at the end of a shaft. In a normal position, the actuating element is secured against rotation with respect to the housing by a ratchet. In the case of locking authorization, the actuating element can be rotated relative to the housing. The actuating element is coupled to the shaft, so that when the locking mechanism is released, the bolt can be brought from a blocked position into a released position.

the DE 34 24 943 A1 discloses a lock that can be fastened to a door leaf and has an actuating element designed as a rotary knob is coupled with locking authorization with a handle mandrel to close a mortise lock located in the door. Authorization to lock is determined by inserting a key card into a slot in the lock housing.

the DE 203 17 239 U1 discloses a lockset in which a lock is connected to a clutch with a lock mandrel. In a coupled position, the handle mandrel is carried along when the handle is rotated. This does not occur in a non-clutched position.

the DE 201 00 424 U1 describes a profile cylinder with a knob.

From the EP 2 840 204 B1 a profile cylinder with a knob is known, in which a predetermined breaking point is provided. If the predetermined breaking point breaks, the knob can shift axially, so that a blocking pin enters a blocking recess, so that the knob can no longer be rotated.

the EP 3 670 791 B1 describes a double lock cylinder with a clutch which couples one of the two cylinder cores to a locking element, elements of the clutch being able to be displaced with the tip of a key inserted into the keyway of the cylinder core.

Furniture locks are also known from the prior art in which an actuating element has a reading device with which an electronic key, for example a transponder, can be read. If the electronic key has locking authorization, the actuating element is coupled to a coupling element, so that the rotary movement of the actuating element can be transmitted to the bolt. When the operating member is not coupled to the coupling member, the operating member can be rotated freely.

Summary of the Invention

The object of the invention is to improve the locking security of a lock characterized at the outset.

The object is achieved by the invention specified in the claims, the subclaims not only being advantageous developments of the lock specified in the main claim, but also representing individual solutions to the problem.

First and foremost, a rotation-inhibiting latching connection between the driven part and the housing is proposed. As a result of this rotation-inhibiting latching connection, the driven part and the closing element interacting with it, for example the bolt carried by the driven part, remain in a defined rotational position in an operating position in which the driven part is not coupled to the actuating element, i.e. either in a release position or in a locked position . In the coupling state, in which the actuating element is rotationally coupled to the driven part, a torque can be applied to the driven part. With this torque, the latching connection between the driven part and the housing is to be canceled in order to shift the closing element by further subsequent rotation of the driven part, for example to shift the latch between the locked position and the release position. In one embodiment of a lock according to the invention, the driven part is in an initial position, which can be a locked position or a release position of the bolt, but which can also be an intermediate position, latched to the housing, so that the bolt cannot move into its operating position due to vibrations or gravity , For example, the locked position or release position can leave. In this operating position, the actuating element cannot be coupled to the driven part, so that it can rotate freely. Used by plugging a key with locking authorization or by bringing a transponder with locking authorization close to the actuating element, locking authorization is recognized, a coupling projection can enter a coupling recess of the driven part in order to establish a non-rotatable connection between the actuating element and the driven part. If a torque is then applied to the actuating element, this is transmitted to the driven part via the clutch connection. This torque and in particular an initial rotation of the actuating element lead to the release of the locking connection. For this purpose it can be provided in particular that the snap-in connection forms a first snap-in element which is firmly connected to the housing. A second locking element can be provided, which is formed by the driven part. One of the two latching elements can be displaceable relative to the housing and against the restoring force of a spring element. The other locking element can be axially fixed relative to the housing. For example, if one of the locking elements has a locking projection that can engage in one of several locking recesses of the other locking element in different rotary positions of the driven part corresponding locking positions, the driven part can be locked in different rotary positions. It can be provided that an axially movable latching element surrounds a coupling element of the driven part. The latching element can be an annular body and the coupling element can be coupled to the actuating element in the manner described above. In the latching positions, a latching element formed by a pin can engage in the latching depressions. Provision can be made for the latching projection to be formed by a free end of a pin which is inserted in a bore in the housing and whose free end engages freely in a cavity in the housing in which the driven part is located. Provision can also be made for the axially movable latching element to be acted upon by a spring element. The spring element preferably acts in an axial direction in relation to the axis of rotation of the driven part and acts on the locking element into the locking position. A rotation of the coupling element relative to the latching element can lead to an axial displacement of the latching element, which causes the latching projection to emerge from the latching recess. In an exemplary embodiment of the invention, it is provided that the coupling element has a control bevel which interacts with a control element. The control element can be a control element that is firmly connected to the axially movable latching element and can be formed by a diagonal pin. The control bevel can be formed by a V-slot of the coupling element. The coupling element preferably has two V-recesses through which a control pin reaches. The opening of the coupling element, into which one end of a control pin preferably engages, can also be heart-shaped. The control element connected to the axially movable latching element preferably interacts with the control bevel of the coupling element in such a way that a relative rotation of the coupling element with respect to the axially movable latching element results in an axial displacement of the latching element, in which case the latching connection is released. It can be provided that the locking element has a ring shape. The ring body formed in this way has two diagonally opposite bores, in each of which a free end of a control pin is inserted. In a development of the invention, it is provided that the driven part has a driven element. Furthermore, it can be provided that the coupling element has an end face which is supported on a support shoulder of the driven element. The driven part or driven element can have a threaded section which protrudes backwards out of the housing cavity of the housing and to which the pivot bolt is fastened. The coupling element can be plugged into a cavity of the driven element that is open toward its end face. The bottom of this cavity can form the support shoulder. Provision can also be made for the output element to form a guide slot or, in particular, two diagonally opposite guide slots, in which the control pin rests in an axially movable manner. During the release of the locking connection can in the to Twist the coupling element lying in the open cavity of the output element relative to the output element. The detent element cannot twist relative to the output element because the control pin, which is connected to the detent element in a rotationally fixed manner, is guided in the guide slots of the output element. During this rotary displacement of the coupling element, however, the latching element can shift in the axial direction relative to the driven part or driven element. In a further development it is provided that the locking depressions are arranged on a narrow edge of the ring-shaped locking element. For this purpose, the narrow edge of the latching element can form a free space that extends over a circumferential angle of approximately 90°. The two ends of the free space can form stops. The detent depressions can be located in a wall of the free space that extends on a peripheral line, so that the detent pin, which engages in the free space or also the detent depressions, also forms a rotary stop at the same time, with which the angle of rotation by which the driven part or the elements of the output section can be rotated is limited. In a development, it is also provided that the driven part or driven element has a recess, which is preferably a circumferential recess that extends over a limited circumferential area. The locking pin and in particular a locking projection formed by the locking pin can reach through this recess, so that the two ends of the recess also form rotary stops. To generate the spring force that holds the latching elements in their latching position, a tension spring can be provided which has a first end which acts on the control pin. The tension spring can extend through a central cavity of the driven part or driven element. The other end of the tension spring may be attached to a pin which crosses the central cavity of the output part or element. With the spring element, a spring force can thus be applied between the latching element and the driven part. The invention can be implemented in a furniture lock, which has an elongated housing in an opening of a drawer or a Furniture door can be used. The furniture lock can be operated with a rotary knob. When the furniture lock is actuated, a swivel bolt can be pivoted, which in a restrained position restrains the drawer or the furniture door in a closed position. In a release position, the drawer or the furniture door can be opened.

In addition, the invention can also be implemented on other locks, for example a lock cylinder. An exemplary embodiment of the invention is, for example, a lock cylinder and in particular a knob cylinder. The lock cylinder has a housing that has, for example, a standard cross-sectional profile. The lock cylinder can be a half cylinder or a double lock cylinder. It is in particular a knob cylinder. An actuator, which forms the actuating element and can be a shaft, is inserted in a core bore of the housing. An operating knob can be connected to this shaft. The shaft is connected to a clutch which is arranged in the housing and which can interact with a locking element. If a torque is exerted on the clutch, for example by applying a corresponding torque to the shaft, a latching element can be brought out of a latched position along with a first rotation of the shaft or an actuating button seated on the shaft. The locking element is preferably non-rotatably connected to the coupling element. In the latched position, however, the latching element is restrained against rotation relative to the housing by means of a latching projection, for example the free end of a latching pin. The first rotation of the shaft, which preferably takes place against the restoring force of a spring element, leads to a displacement of the locking element, in particular in the axial direction, so that the locking projection emerges from a locking opening of the locking element and thus releases the locking element for rotation. As soon as the locking element has assumed its release position, the driven element can be rotated. It can be provided in particular be that the coupling element interacts with the driven element in such a way that a relative movement and in particular a relative rotation between the coupling element and the driven element brings the locking element from its locking position into a release position. This takes place against the restoring force of a spring element. The spring element can be a compression spring which is supported on the actuator, for example a shaft inserted in the housing cavity. For this purpose, the shaft can have an end bore, in which the compression spring is inserted, which can act on a transmission element, which has an opening, which is in particular a transverse bore, in which a control pin is inserted, which is located by the spring in a crest area of two control bevels, the V - literally stand by each other. The two control bevels are formed by the coupling element, which is non-rotatably connected to the actuator. The coupling element can also be connected to the actuator in the same material. The control pin crossing the coupling element can engage in a guide slot of the driven element. Provision is made in particular for the two ends of the control pin to engage in bores in the latching element and in an opening, for example a guide slot, in the driven element. The locking pin can be inserted in a borehole arranged in the profile section of the housing of the lock cylinder. A latching projection of the latching pin can protrude from this bore and interact with the latching depressions of the latching element arranged on a circular arc. The driven element can transmit its rotation to the rotation of a locking element, with which a mortise lock can be actuated, for example. An optional coupling can be provided with which the driven element can be brought into a non-rotatable connection with the closing element. This is provided in particular when the lock cylinder is a double lock cylinder in which a cylinder core is inserted in one housing half, which cylinder core can be turned with a key and which is held in a locked position with tumbler pins. If the key has an authorized mechanical coding, the tumbler pins sorted in such a way that the cylinder core can be rotated. For this purpose, the cylinder core is coupled to the closing element with the help of the clutch. The output element can then not be coupled to the closing element. However, it can also be provided that the output element is permanently coupled in rotation to the closing element and the latching connection between the latching element or the output element and the housing is canceled with the key. The closing element can also be turned by turning a knob if the latching connection is released by applying a torque. Due to a preferably permanent rotary connection of the driven element, the rotary movement of the knob is transmitted to the closing element. On the other hand, the driven element can also be coupled to the locking member via the clutch if the locking cylinder is to be actuated via the actuating button which interacts with the actuator. To this end, it is advantageous if, along with the displacement of the latching element from the latched position to the release position, a transmission element is displaced, which interacts with the clutch in such a way that an axial displacement of the transmission element leads to a clutch of the closing element with the output element. For this purpose, a driver acted upon by a spring can be displaced axially in the direction of the closing element, so that the driver, which interacts with driving flanks of the driven element, can be coupled to the closing element in a rotationally fixed manner.

The invention relates to a lock cylinder with a cylinder core which, when a key is inserted into a key channel of the cylinder core, can be brought with a locking element into a coupling position which transmits rotation from the key to the locking element. With the above-described in particular ring-shaped latching element, a driven element which is permanently coupled in rotation with the closing element can be held in a latching position which is non-rotatable with respect to the housing. Due to the rotary coupling of the output element to the closing element, the closing element is also relative to the housing as long as non-rotatable until the locking elements are brought out of their locking position. According to an independent solution to the problem of further developing a lock cylinder in a user-friendly manner, this can be done by the key tip of the key inserted in the keyway displacing a transmission element in such a way that the locking connection between the two locking elements is canceled. With this measure, the security of a lock cylinder is improved since the locking element receives an additional rotation restriction, which acts in particular on the inside of the door, since the latching elements are arranged on the side of the lock cylinder opposite the cylinder core actuated by a key.

Description of the embodiments

That in the Figures 1 to 16 lock shown consists essentially of a housing 9, which has a thread on its peripheral surface, onto which a fastening nut can be screwed. The front of the housing 9 has an edge overhang. The threaded portion of the housing 9 can be inserted into a hole in a cabinet door or the like and secured to the cabinet door by screwing the nut backwards.

The housing 9 has a housing cavity 22 in which an actuator 2 is inserted. The actuator 2 has a mechanical coupling with a coupling projection 26 in a coupling recess 25 of a coupling element 3 can intervene. An actuating element 1 forms a rotary knob with which the lock can be operated. In a housing of the actuating element 1 there can be an electronic circuit which interacts with a reading device in order to read out an identifier of a transponder. If the transponder has locking authorization, the actuator 2 , which is non-rotatably connected to the actuating element 1 , is connected to the coupling element 3 in that the coupling projection 26 engages in a coupling recess 25 . If the transponder does not have locking authorization or if the lock is in a normal state, the coupling projection 26 does not engage in the coupling recess 25, so that the actuating element 1 and the actuator 2 connected thereto in a rotationally fixed manner can be rotated freely in relation to the housing 9.

In addition, a driven part 3 , 4 , 7 , which is formed by the coupling element 3 , a latching element 4 and a driven element 7 , is inserted in the cavity 22 of the housing 9 . The coupling part can also include other elements, such as a control pin 5, a tension spring 6 or a pin 23.

The driven element 7 has a threaded section 28 onto which nuts 29 can be screwed. A swivel bolt 14 can be fastened to the free end of the driven element 7 with the nuts 29 . The bolt can be connected to the output element 7 in a torque-proof manner.

The output element 7 has a central cavity and a cavity which is open on the side facing away from the thread 28 and forms a supporting shoulder 20 with its base. The wall of the driven element 7 surrounding the cavity has a recess 24 which is open in the circumferential direction and has narrow sides 24' which form stops.

The wall of the cavity of the output element 7 also forms two diametrically opposite guide slots 18 in which the control pin 5 can be displaced in the axial direction relative to the axis of rotation of the actuating element 1 .

An end face 21 of the coupling element 3 can be supported on the support shoulder 20 and has a section which engages in the cavity of the driven element 7 . On its side facing away from the end face 21, the coupling element 3 has the coupling recesses 25 for the entry of the coupling projection 26.

Like the driven element 7, the coupling element has a central cavity. The central cavity is surrounded by a wall which belongs to a section of the clutch element 3 engaging in the cavity of the driven element 7 . A V-slot is located there, which forms control bevels 19' with sloping edges.

The edge surrounding the cavity of the driven element 7 is surrounded by a latching element 4, which has a ring shape and two diametrically opposite bores 27, in which the two ends of the control pin 5 are tied up. The control pin 5 reaches through the V-slot 19 and lies in the guide slots 18 of the driven element 7 .

A locking pin 11 is inserted in a bore 30 of the housing 9. The locking pin 11 has a free end which forms a locking projection 11' which projects into the housing cavity 22. The latching projection 11′ reaches through the recess 24 of the driven element 7, so that the driven element 7 can only rotate through a limited angle of rotation, which is limited by the angular distance between the two stops 24′.

The latching projection 11 ′ also engages in a free space 31 of the latching element 4 which extends over a circumferential angle and which is open towards one end face of the latching element 4 . The two angularly offset ends of the free space 31 pointing away from each other form stops 32 for limiting the rotation of the locking element 4.

The peripheral edge of the free space 31 extending in the circumferential direction has a plurality of latching depressions 16 which are angularly offset from one another. This rotational coupling between the locking projection 11 ′ and the locking element 4 can be canceled by an axial displacement of the locking element 4 , so that the locking element 4 can be rotated relative to the housing 9 . Provision is made in particular for the latching element 4 to be able to rotate by at least 90° with respect to the housing 9 and latch in at least two intermediate positions. However, this angle can also be smaller, for example 30°.

The locking position is maintained by means of a spring element, which is formed by a tension spring 6 in the exemplary embodiment. To this end, a free end of the tension spring 6 acts on the control pin 5 . The tension spring 6 extending through the central cavity of the coupling element 3 and the central cavity of the output element 7 is attached at its other end to the pin 23 which is firmly connected to the output element 7 .

The operation of the lock is as follows:

In a normal position, the coupling projection 26 does not engage in the coupling recess 25 so that the actuating element 1 and the actuator 2 firmly connected thereto can be rotated freely with respect to the housing 9 .

The latching pin 11 engages with its latching projection 11 ′ in one of the latching recesses 16 of the latching element 4 so that the latching element 4 cannot be twisted relative to the housing 9 . The control pin 5, which is assigned to the locking element 4 in a rotationally fixed manner, also lies in the guide slot 18 of the driven element 7, so that the entire driven part, in particular made up of the coupling element 3, the driven element 7 and the locking element 4, cannot rotate. The bolt 14 fixed in a rotationally fixed manner on the driven element 7 is thus held in a rotationally fixed position relative to the housing 9 .

If a key element with locking authorization is used to actuate actuating element 1, which, depending on the design of actuating element 1, can be a mechanical or an electronic key such as a transponder, for example, coupling projection 26 is brought into coupling recess 25, so that actuating element 1 a torque can be applied to the coupling element 3 . The sloping control bevel 19' of the V-slot 19 is now supported on the control pin 5, so that the force acting in the circumferential direction on the control pin 5 generates an axial component which shifts the locking element 4 relative to the coupling element 3, so that the locking projection 11' comes out of the locking recess 16. As soon as the locking projection 11' has emerged from the locking recess 16, the axial restraint of the locking element 4 on the housing is missing, so that the locking element 4 can rotate in the circumferential direction until the locking projection 11' can enter the locking recess 16 following in the circumferential direction. Along with this, because of the non-rotatable coupling of the latching element 4 to the driven element 7, the driven element 7 and the bolt 14 connected thereto are also pivoted further. If the actuating element is rotated continuously, the driven element 7 and thus the bolt 14 can be rotated from a stop position to the stop position. This turning process is not interrupted as soon as the next possible detent position is reached. Only when the turning process has ended, that is to say no more torque is applied to the actuating element 1 and the coupling between the actuator 2 and the coupling element 3 is released, does the latching function take effect.

A further application of torque to the actuating element leads to a renewed axial displacement of the locking element 4 and the exit of the locking projection 11' from the locking recess 16, so that the locking element 4 can continue to rotate together with the driven element 7 and the bolt 14 connected thereto.

In this sequence, the bolt 14 can be displaced between a locked position and a locked position.

In the exemplary embodiment, the bolt 14 is a rotary bolt which can be rotated about an axis of rotation, the axis of rotation being the axis of rotation of the actuating element.

That in the Figures 17-28 illustrated embodiment is a lock cylinder. The exemplary embodiment represents a double lock cylinder which has two cylinder halves. In the in the figure 19 The half shown on the left can insert a cylinder core 44, which can be turned by a key, for which purpose the cylinder core 44 has a key channel 42 in a known manner, into which the key can be inserted in order to insert tumbler bores not shown in the drawings into cylinder-side and housing-side tumbler bores Sort tumbler pins in such a way that the cylinder core 44 can be rotated. The tip of the key can shift a transmission link 41 so that a driver 40 couples the cylinder core 44 to a locking element 14 so that a rotation of the key leads to a rotation of the locking element 14 . If the key is pulled out of the cylinder core 44 again, a spring element 39 causes an axial displacement of the driver 40 into a position in which the cylinder core 44 is not rotationally coupled to the closing element 14 . The lock cylinder can be inserted into a door in which there is a mortise lock which is actuated by the rotation of the locking member 14.

In the in the figure 19 A device is arranged in the half of the lock cylinder shown on the right, as has essentially already been described above. The rotary movement of a turning knob, not shown, which is placed on an extension 43 of an actuator 2 is transmitted to the actuator 2 . The actuator 2 forms an actuating element 1 and in a normal state is connected to the housing 9 in a non-rotating manner in order to rotate an output element 7 if a latching connection between a coupling element 3 or the output element 7 and the housing 9 has previously been released. In the course of releasing the locking connection, a transmission element 33 is displaced in an axial direction. The closing element 14 is connected in a rotationally fixed manner to the driven element 7 by means of the driver 37 , so that a rotational movement transmitted to the driven element 7 is transmitted to the closing element 14 .

In an embodiment not shown is a half cylinder in which the in the figure 19 Half of the lock cylinder shown on the left is missing. The half cylinder can only be actuated by a knob.

The actuator 2 , which can be rotated about an axis of rotation, is inserted in a housing cavity 22 of the housing 9 formed by a bore, this axis of rotation corresponding to the axis of rotation of the cylinder core 44 and the closing element 14 . The actuator 2 is restrained axially in the housing cavity 22 with a C-ring.

A tubular extension, which forms a coupling element 3 , protrudes from an end face of the actuator 2 protruding into the housing cavity 22 . A bore 45 is formed, in which the axially displaceable transmission member 33 is inserted. The transmission element 33 is acted upon in the axial direction by a compression spring 6 which is supported on the bottom of the bore 45 .

The wall of the coupling element 3 has two heart-shaped openings 19 lying opposite one another, which form two control bevels 19' which stand in a V-shape relative to one another. The transmission member 33 has an opening 34 extending in the radial direction, in which a control pin 5 is inserted. The two ends of the control pin 5 engage through the openings 19 therethrough. The spring element 6 acts on the transmission element 33 in such a way that the control pin 5 lies in the apex area of the two control bevels 19'.

The coupling element 3 is inserted in an annular latching element 4, which has radial, opposite bores 27 into which the outer ends of the control pin 5 protrude, so that the latching element 4 is coupled to the transmission member 33 in a rotationally fixed manner. However, the latching element 4 can shift slightly relative to the coupling element 3 if the ends of the control pins 5 move along the control slope 19' away from the apex of the control slopes 19'.

A locking pin 11 is inserted in a bore 30 of the housing 9 and forms a locking projection 11' with a free end. The latching projection 11 ′ engages in one of several latching recesses 16 of the latching element 4 . The latching element 4 is an annular body which forms an essentially smooth-walled end face which is opposite an end face of the actuator 2 surrounding the coupling element 3 . A face of the latching element 4 pointing away therefrom has a multiplicity of latching depressions over the entire circumference 16, into which the latching projection 11' can engage in order to latch the latching element 4 to the housing 9 in a rotationally fixed manner. The spring element 6 acts on the locking element 4 in its locking positions.

A cylindrical section of the transmission element 7 is inserted in an annular space between the peripheral wall of the coupling element 3 and the inner wall of the latching element 4. The cylindrical section of the transmission element 7 has a diametrical guide slot 18 in which the control pin 5 lies, so that the latching element 4 can rotate with it the output element 7 is connected. On the side opposite the guide slot 18, the driven element 7 forms a plurality of driving flanks 36, which can interact with the driver 37 when the latter has been brought into the intermediate space between the driving flanks 36 by axial displacement.

The operation of the lock cylinder is as follows:

In a normal position, the Figures 19 to 21 and 25 and 26 represent, no torque is applied to the actuator 2. The spring element 6 acts on the transmission element 33 in the direction of the closing element 14. The driver 37, which lies between the driving flanks 36 of the driven element 7, is coupled in a rotationally fixed manner to the closing element 14, so that the closing element 14 can only be rotated if the locking elements have previously been locked 4, 11 have been brought into a release position. The output element 7 is thus permanently non-rotatably connected to the closing element 14 .

In this operating position, the latching element 4 is acted upon by the control pin 5 in the direction of the closing element 14 in such a way that the latching projection 11 ′ engages in one of the many latching depressions 16 of the latching element 4 . In these locking positions, the locking element 4, the transmission member 33 and the output element 7 is connected to the housing 9 in a rotationally fixed manner. The actuator 2 is also tied to the housing 9 in a rotationally fixed manner in this position.

If a torque is exerted on the actuator 2, the locking pin 5 can slide along one of the two control slopes 19'. This is associated with an axial displacement of the control pin 5 and, consequently, with an axial displacement of the latching element 4, so that the latching projection 11' is released from the latching recess 16. Along with this, the latching element 4 and the further elements coupled in a torque-proof manner to the latching element 4, in particular the driven element 7, the transmission element 33 and the actuator 2, can be rotated further.

In order to actuate the lock cylinder with a key inserted into the key channel 42, the latching elements 4, 11 must first be disengaged from the latching engagement. For this purpose, a transmission element 41 is provided, which is supported on the driver 40 with a compression spring 39 . The transmission member 41 is supported on the extension 35 of the transmission member 33 from. The driver 40 is subjected to a force against the driver 37 with a compression spring 38 so that when the key is not inserted into the key channel 42 the driver 40 does not cause a non-rotatable connection between the cylinder core 44 and the locking element 14 . When the key is not inserted, the locking element 14 is connected to the housing 9 in a rotationally fixed manner via the latching elements 4 , 11 .

If the key is inserted into the key channel 42, this non-rotatable connection between the locking element 14 and the housing 9 is canceled by the locking element 4 being displaced in the axial direction so that the locking projection 11' leaves the locking recess 16. When the key is inserted, the tip of the key acts on the transmission element 41 and displaces it in the axial direction. This has the consequence that the transmission element 41 against the Face of the extension 35 of the transmission member 33 acts and the latter is displaced in the axial direction. At the same time, the latching element 4 is also displaced in the axial direction in such a way that the latching projection 11′ emerges from the council recess 16 and the locking element 14 is thus prevented from rotating. In the course of this axial displacement of the key, the driver 40 couples the cylinder core 44 to the locking element 14 in a rotationally fixed manner, so that the locking element 14 can be rotated by turning the key.

If the key is then pulled out of the key channel 42 of the cylinder core 44 again, the transmission element 41 is displaced by the force of the relaxing compression spring 39 and the driver 40 is displaced by the relaxing compression spring 38 back into the operating position shown in Figure 32 , in which the driver 40 is not rotationally coupled to the closure member 14. The compression spring 6 tensioned during the axial displacement of the transmission element 33 relaxes, so that the locking element 4 is also brought back into the locking position.
