Description

field of technology

[0001] The invention relates to a lock with an actuating element rotatably arranged in a housing, which is coupled to an output part rotatably mounted in the housing for transmitting a rotation to the output part only in the case of a locking authorization, wherein the output part has a locking element, for example a bolt or a locking member, which can be displaced between a blocking position and a release position by rotating the actuating element.

[0002] The invention further relates to a locking cylinder with a cylinder core which is rotationally coupled to a locking member when a key is inserted into a key channel of the cylinder core. State of the art

[0003] DE 2522351 U1 discloses a furniture lock in which a bolt with a crank rod is driven by a rotary disc. The latter, in turn, is rotated by the cam of a locking cylinder. The rotary disc interacts with a linearly movable tumbler element.

[0004] FR 2522351 A1 describes a locking cylinder with tumbler elements that can enter an escape recess of a rotatable element when the rotatable element has been brought into a release position by turning a key.

[0005] US 2,036,768 A describes a locking cylinder in which the key tip has coding recesses that can interact with axially displaceable locking slides. The locking slides can emerge from locking openings in an annular part that is rotationally and axially fixedly coupled to the housing.

[0006] DE 11 2007 001 299 B4 describes a so-called cam lock for a door or cabinet. A handle-shaped actuating element is located in a cavity in a housing, which can be rotated to operate a pivot bolt located at the end of a shaft. In its normal position, the actuating element is secured against rotation relative to the housing by a locking mechanism. When authorized to lock, 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 moved from a locked position to a released position.

[0007] DE 34 24 943 A1 discloses a lock that can be attached to a door leaf and has an actuating element designed as a rotary knob. When authorized to lock, this actuating element is coupled to a handle to close a mortise lock located in the door. Authorization to lock is established by inserting a key card into a slot in the lock housing.

[0008] DE 203 17 239 U1 discloses a handle assembly in which a handle is connected to a coupling with a handle spindle. In a coupled position, the handle spindle is driven when the handle is turned. This does not occur in a non-coupled position.

[0009] DE 201 00 424 U1 describes a profile cylinder with a knob.

[0010] EP 2 840 204 B1 discloses a profile cylinder with a knob in which a predetermined breaking point is provided. If the predetermined breaking point breaks, the knob can shift axially, causing a locking pin to enter a locking recess, preventing the knob from turning.

[0011] EP 3 670 791 B1 describes a double locking cylinder with a coupling that couples one of the two cylinder cores to a locking member, wherein elements of the coupling can be moved with the tip of a key inserted into the keyway of the cylinder core.

[0012] Furthermore, furniture locks are known from the prior art in which an actuating element has a reading device with which an electronic key, such as 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. If the actuating element is not coupled to the coupling element, the actuating element can be rotated freely. Summary of the invention

[0013] The invention is based on the object of improving the locking security of a lock characterized at the beginning.

[0014] The object is achieved by the invention specified in the independent claims, wherein the subclaims are advantageous developments of the lock specified in the main claim.

[0015] First and foremost, a rotation-preventing locking connection between the driven part and the housing is proposed. As a result of this rotation-preventing locking connection, the driven part and the locking element interacting with it, for example, the bolt carried by the driven part, remain in a defined rotational position—i.e., either in a release position or a locked position—in an operating position in which the driven part is not coupled to the actuating element. In the coupled state, in which the actuating element is rotationally coupled to the driven part, a torque can be applied to the driven part. This torque is intended to release the locking connection between the driven part and the housing in order to displace the locking element through further rotation of the driven part, for example, to displace the bolt between the locked position and the release position.In one embodiment of a lock according to the invention, the driven part is locked to the housing in an initial position, which can be a locked position or a released position of the bolt, but can also be an intermediate position, so that the bolt cannot leave its operating position, for example the locked position or released position, due to vibrations or gravity. The actuating element can be uncoupled from the driven part in this operating position, so that it can rotate freely. If a locking authorization is recognized by inserting a key with locking authorization or by bringing a transponder with locking authorization close to the actuating element, a coupling projection can enter a coupling recess in the driven part in order to create a rotationally fixed connection between the actuating element and the driven part.If a torque is subsequently applied to the actuating element, it is transferred to the output part via the coupling connection. This torque and in particular an initial rotation of the actuating element lead to the cancellation of the locking connection. For this purpose, the locking connection is provided with a first locking element that is connected to the housing in a rotationally fixed manner. A second locking element is provided, which is formed by the output part. One of the two locking elements can be moved 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. If, for example, 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 rotational positions of the output part, the output part can be locked in different rotational positions.It can be provided that an axially movable locking element surrounds a coupling element of the output part. The locking element is an annular body and the coupling element can be coupled to the actuating element in the manner described above. In the locking positions, a locking element formed by a pin can engage in the locking recesses. It can be provided that the locking projection is formed by a free end of a pin which is inserted into a bore in the housing and whose free end freely engages a cavity in the housing in which the output part is located. It can further be provided that the axially movable locking element is acted upon by a spring element. The spring element preferably acts in an axial direction relative to the axis of rotation of the output part and acts on the locking element into the locking position.

[0016] A rotation of the coupling element relative to the locking element can lead to an axial displacement of the locking element, which causes the locking projection to emerge from the locking recess. In one embodiment of the invention, the coupling element has a control bevel that interacts with a control element. The control element can be a control element that is firmly connected to the axially movable locking element and can be formed by a diagonal pin. The control bevel can be formed by a V-slot in the coupling element. The coupling element preferably has two V-recesses through which a control pin engages. The opening in 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 locking 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 locking element results in an axial displacement of the locking element, which releases the locking connection. The locking element has a ring shape. The ring body thus formed has two diagonally opposite bores, in each of which a free end of a control pin is inserted. In a further development of the invention, it is provided that the output part has an output element. Furthermore, it can be provided that the coupling element has an end face that is supported on a support shoulder of the output element. The output part or output element can have a threaded portion that protrudes rearward from the housing cavity of the housing and to which the pivot bolt is fastened.The coupling element can be inserted into a cavity in the output element that is open towards its front side. The base of this cavity can form the support shoulder. It can further be provided that the output element forms a guide slot or, in particular, two diagonally opposite guide slots in which the control pin lies for axial movement. During the release of the locking connection, the coupling element lying in the cavity of the output element that is open towards the front side can rotate relative to the output element. The locking element cannot rotate relative to the output element because the control pin, which is connected to the locking element in a rotationally fixed manner, is guided in the guide slots of the output element. However, during this rotational displacement of the coupling element, the locking element can move in the axial direction relative to the output part or output element.The locking recesses are arranged on a narrow edge of the annular locking element. For this purpose, the narrow edge of the locking 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 locking recesses can be located in a wall of the free space extending along a circumferential line, so that the locking pin, which engages in the free space or the locking recesses, simultaneously also forms a rotation stop, with which the angle of rotation by which the output part or the elements of the output part can be rotated is limited. In a further development, it is further provided that the output part or output 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 extend through this recess, so that the two ends of the recess also form rotation stops. To generate the spring force that holds the locking elements in their locked position, a tension spring can be provided, which has a first end that engages the control pin. The tension spring can extend through a central cavity of the output part or output element. The other end of the tension spring can be attached to a pin that crosses the central cavity of the output part or output element. The spring element can thus apply a spring force between the locking element and the output part. The invention can be implemented in a furniture lock having an elongated housing that can be inserted into an opening in a drawer or furniture door. The furniture lock can be operated with a rotary knob.When the furniture lock is operated, a swivel bolt can be pivoted, which, in a locking position, locks the drawer or furniture door in a closed position. In a release position, the drawer or furniture door can be opened.

[0017] The invention can, however, also be implemented on other locks, for example a locking cylinder. One exemplary embodiment of the invention is a locking cylinder, and in particular a knob cylinder. The locking cylinder has a housing which, for example, has a standard cross-sectional profile. The locking cylinder can be a half cylinder or a double locking cylinder. In particular, it is a knob cylinder. An actuator which forms the actuating element and can be a shaft is inserted into a core bore in the housing. An actuating knob can be connected to this shaft. The shaft is connected to a coupling arranged in the housing which can interact with a locking element. If a torque is exerted on the coupling, for example by applying a corresponding torque to the shaft, a first rotation of the shaft orA locking element can be moved from a locking position using an actuating button on the shaft. The locking element is preferably connected to the coupling element in a rotationally fixed manner. In the locking position, however, the locking element is held against rotation relative to the housing by means of a locking projection, for example the free end of a locking pin. The first rotation of the shaft, which preferably occurs against the restoring force of a spring element, leads to a displacement of the locking element, particularly in the axial direction, so that the locking projection emerges from a locking opening in the locking element and thus releases the locking element for rotation. As soon as the locking element has assumed its release position, the output element can be rotated.In particular, it can be provided that the coupling element interacts with the output element in such a way that a relative movement and in particular a relative rotation between the coupling element and the output element moves the locking element from its locked position into a release position. This occurs counter to the restoring force of a spring element. The spring element can be a compression spring that is supported on the actuator, for example a shaft inserted in the housing cavity. For this purpose, the shaft can have a front bore in which the compression spring is inserted, which can act on a transmission element that has an opening, which is in particular a transverse bore, in which a control pin is inserted, which is located by the spring in an apex region of two control slopes that are arranged in a V-shape relative to one another. The two control slopes are formed by the coupling element, which is connected to the actuator in a rotationally fixed manner.The coupling element can also be connected to the actuator using the same material. The control pin crossing the coupling element can engage in a guide slot of the output element. In particular, it is provided that the two ends of the control pin each engage in bores of the locking element and engage in an opening, for example a guide slot of the output element. The locking pin can be inserted into a bore arranged in the profile section of the housing of the locking cylinder. A locking projection of the locking pin can protrude from this bore and interact with the locking recesses of the locking element arranged on a circular arc. The output element can transmit its rotation to the rotation of a locking element, with which, for example, a mortise lock can be operated. An optional coupling can be provided with which the output element can be brought into a rotationally fixed connection with the locking element.This is particularly intended when the locking cylinder is a double locking cylinder in which a cylinder core is inserted into one housing half, which can be turned with a key and which is held in a locked position by tumbler pins. If the key has a mechanical coding that authorises locking, the tumbler pins are arranged in such a way that the cylinder core can be turned. For this purpose, the cylinder core is coupled to the locking element using the coupling. In this case, the output element cannot be coupled to the locking element. However, it can also be provided that the output element is permanently rotationally coupled to the locking element and the locking connection between the locking element or the output element and the housing is released using the key. The locking element can also be turned by turning a knob if the locking connection is released by applying torque.Due to a preferably permanent rotary connection of the output element, the rotary movement of the knob is transmitted to the locking element. On the other hand, the output element can also be coupled to the locking element via the coupling if the locking cylinder is to be actuated via the actuating button, which interacts with the actuator. For this purpose, it is advantageous if, along with the displacement of the locking element from the detent position to the release position, a transmission element is displaced. This transmission element interacts with the coupling in such a way that an axial displacement of the transmission element leads to a coupling of the locking element with the output element. For this purpose, a driver acted upon by a spring can be displaced axially towards the locking element so that the driver, which interacts with driving flanks of the output element, can be coupled to the locking element in a rotationally fixed manner.

[0018] The invention relates to a locking cylinder with a cylinder core that, when a key is inserted into a keyway of the cylinder core, can be brought into a coupling position with a locking element, transmitting rotation from the key to the locking element. With the previously described annular locking element, an output element permanently coupled to the locking element can be held in a rotationally fixed locking position relative to the housing. Due to the rotational coupling of the output element to the locking element, the locking element is also rotationally fixed relative to the housing until the locking elements are moved out of their locking position.According to an independent solution to the problem of developing a locking cylinder in a practical manner, this can be achieved by having the tip of the key inserted into the keyway displace a transmission element in such a way that the locking connection between the two locking elements is eliminated. This measure improves the security of a locking cylinder because the locking element receives an additional rotational lock, which is particularly effective on the inside of the door, since the locking elements are arranged on the side of the locking cylinder opposite the cylinder core actuated by a key.

Description of the embodiments

[0020] The Figures 1 to 16The lock shown essentially consists 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 a protruding edge. 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 on from the rear.

[0021] 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 that can engage in a coupling recess 25 of a coupling element 3. An actuating element 1 forms a rotary knob with which the lock can be operated. An electronic circuit can be located in a housing of the actuating element 1, which interacts with a reading device to read an identifier from a transponder. If the transponder has locking authorization, the actuator 2, which is connected to the actuating element 1 in a rotationally fixed manner, is connected to the coupling element 3 by the coupling projection 26 engaging 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 relative to the housing 9.

[0022] Furthermore, an output part 3, 4, 7 is located in the cavity 22 of the housing 9, which is formed by the coupling element 3, a locking element 4, and an output element 7. The coupling part may also include other elements, such as a control pin 5, a tension spring 6, or a pin 23.

[0023] The output element 7 has a threaded portion 28 onto which nuts 29 can be screwed. A pivot bolt 14 can be attached to the free end of the output element 7 using the nuts 29. The bolt can be connected to the output element 7 in a rotationally fixed manner.

[0024] The output element 7 has a central cavity and a hollow space open on the side facing away from the thread 28, the bottom of which forms a support shoulder 20. The wall of the output element 7 surrounding the cavity has a recess 24 open in the circumferential direction with narrow sides 24' that form stops.

[0025] The wall of the cavity of the output element 7 also forms two diametrically opposed 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.

[0026] An end face 21 of the coupling element 3, which has a portion that engages into the cavity of the output element 7, can be supported on the support shoulder 20. The coupling element 3 has, on its side facing away from the end face 21, the coupling recesses 25 for the entry of the coupling projection 26.

[0027] The coupling element, like the output element 7, has a central cavity. The central cavity is surrounded by a wall belonging to a section of the coupling element 3 that engages in the cavity of the output element 7. There is a V-slot located there, which, with its inclined edges, forms control bevels 19'.

[0028] The edge surrounding the cavity of the output element 7 is surrounded by a locking element 4, which has a ring shape and two diametrically opposed bores 27 in which the two ends of the control pin 5 are secured. The control pin 5 passes through the V-slot 19 and is located in the guide slots 18 of the output element 7.

[0029] A locking pin 11 is inserted into a bore 30 of the housing 9. The locking pin 11 has a free end which forms a locking projection 11' projecting into the housing cavity 22. The locking projection 11' extends through the recess 24 of the output element 7, so that the output element 7 can only rotate through a limited angle of rotation, which is limited by the angular distance between the two stops 24'.

[0030] The locking projection 11' further engages in a free space 31 of the locking element 4, which extends over a circumferential angle and is open toward one end of the locking element 4. The two angularly offset ends of the free space 31, facing away from each other, form stops 32 for limiting the rotation of the locking element 4.

[0031] The peripheral edge of the free space 31, which extends in the circumferential direction, has a plurality of locking recesses 16 located at an angular offset from one another. The locking recesses 16 serve as the entry point for the locking projection 11' in order to couple the locking element 4 to the housing 9 in the direction of rotation. By axially displacing the locking element 4, this rotational coupling between the locking projection 11' and the locking element 4 can be canceled, so that the locking element 4 can be rotated relative to the housing 9. In particular, it is provided that the locking element 4 can be rotated by at least 90° relative to the housing 9 and can lock in at least two intermediate positions. However, this angle can also be smaller, for example, 30°.

[0032] The locking position is maintained by a spring element, which in the exemplary embodiment is a tension spring 6. For this purpose, a free end of the tension spring 6 engages the control pin 5. The tension spring 6, which extends 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.

[0033] The lock functions 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 freely rotated relative to the housing 9.

[0034] The locking pin 11 engages with its locking projection 11' into one of the locking recesses 16 of the locking element 4, so that the locking element 4 cannot be rotated relative to the housing 9. The control pin 5, which is rotationally fixed to the locking element 4, also lies in the guide slot 18 of the output element 7, so that the entire output part, formed in particular by the coupling element 3, the output element 7, and the locking element 4, cannot rotate. The latch 14, which is rotationally fixed to the output element 7, is thus held in a rotationally fixed position relative to the housing 9.

[0035] If a key element with locking authorization is used to actuate the actuating element 1, which key element can be a mechanical or electronic key such as a transponder depending on the design of the actuating element 1, the coupling projection 26 is brought into the coupling recess 25 so that a torque can be applied to the coupling element 3 using the actuating element 1. The obliquely running control bevel 19' of the V-slot 19 is now supported on the control pin 5 so that the circumferential force acting on the control pin 5 generates an axial component which displaces the locking element 4 relative to the coupling element 3 so that the locking projection 11' emerges from 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 to the housing is no longer present, 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. At the same time, due to the rotationally fixed coupling of the locking element 4 to the output element 7, the output element 7 and the associated latch 14 are also pivoted further. If the actuating element is continuously rotated, the output element 7 and thus the latch 14 can be rotated from one stop position to the stop position. This rotation process is not interrupted once the next possible detent position is reached. The detent function only engages when the rotation process is terminated, i.e., no more torque is applied to the actuating element 1, and the coupling between the actuator 2 and the coupling element 3 is released.

[0036] A further application of a torque to the actuating element leads to a renewed axial displacement of the locking element 4 and to 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 output element 7 and the bolt 14 connected thereto.

[0037] In this sequence, the bolt 14 can be moved between a blocking position and a locking position.

[0038] In the exemplary embodiment, the latch 14 is a rotary latch that can be rotated about a rotation axis, wherein the rotation axis is the rotation axis of the actuating element.

[0039] The Figures 17-28 The illustrated embodiment is a locking cylinder. The embodiment represents a double locking cylinder that has two cylinder halves. Figure 19A cylinder core 44 can be inserted into the half shown on the left, which can be turned by a key. For this purpose, the cylinder core 44 has a keyway 42 in a known manner, into which the key can be inserted in order to sort tumbler pins (not shown in the drawings) inserted into tumbler bores on the cylinder side and the housing side in such a way that the cylinder core 44 can be rotated. The key tip can displace a transmission member 41 so that a driver 40 couples the cylinder core 44 to a locking member 14 so that rotation of the key leads to rotation of the locking member 14. If the key is withdrawn from 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 locking member 14.The locking cylinder can be inserted into a door in which there is a mortise lock which is operated by the rotation of the locking member 14.

[0040] In the in the Figure 19In the half of the locking cylinder shown on the right, a device is arranged, essentially as already described above. The rotary movement of a rotary knob (not shown), which is located 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 rotationally inhibited manner in order to rotate an output element 7 if a locking connection between a coupling element 3 or the output element 7 and the housing 9 has previously been released. When the locking connection is released, a transmission member 33 is displaced in an axial direction. The locking member 14 is connected to the output element 7 by the driver 37 in a rotationally fixed manner, so that a rotary movement transmitted to the output element 7 is transmitted to the locking member 14.

[0041] An embodiment not shown is a half cylinder in which the Figure 19 The half of the locking cylinder shown on the left is missing. The half cylinder can only be operated with a knob.

[0042] The actuator 2 is located in a housing cavity 22 of the housing 9 formed by a bore and can be rotated about a rotational axis, which corresponds to the rotational axis of the cylinder core 44 and the locking member 14. The actuator 2 is axially secured in the housing cavity 22 with a C-ring.

[0043] A tubular extension protrudes from an end face of the actuator 2, which projects into the housing cavity 22, forming a coupling element 3. A bore 45 is formed in which the axially displaceable transmission member 33 is inserted. The transmission member 33 is axially biased by a compression spring 6 supported on the bottom of the bore 45.

[0044] The wall of the coupling element 3 has two opposing heart-shaped openings 19, which form two V-shaped control slopes 19'. The transmission member 33 has a radially extending opening 34 into which a control pin 5 is inserted. The two ends of the control pin 5 extend through the openings 19. The spring element 6 acts on the transmission member 33 such that the control pin 5 lies in the apex region of the two control slopes 19'.

[0045] The coupling element 3 is inserted into an annular locking element 4, which has radial, opposing bores 27 into which the outer ends of the control pin 5 protrude, so that the locking element 4 is rotationally fixedly coupled to the transmission member 33. However, the locking element 4 can shift slightly relative to the coupling element 3 if the ends of the control pins 5 shift along the control slope 19' away from the apex of the control slopes 19'.

[0046] A locking pin 11 is inserted into a bore 30 of the housing 9, the free end of which forms a locking projection 11'. The locking projection 11' engages in one of several locking recesses 16 of the locking element 4. The locking element 4 is an annular body that forms a substantially smooth-walled end face that lies opposite an end surface of the actuator 2 surrounding the coupling element 3. An end face of the locking element 4 facing away from this has a plurality of locking recesses 16 over its entire circumference, into which the locking projection 11' can engage in order to lock the locking element 4 to the housing 9 in a rotationally fixed manner. The spring element 6 urges the locking element 4 into its locking positions.

[0047] A cylindrical section of the transmission element 7 is inserted into an annular space between the peripheral wall of the coupling element 3 and the inner wall of the locking element 4. The cylindrical section of the transmission element 7 has a diametrical guide slot 18 in which the control pin 5 is located, so that the locking element 4 is connected in a rotationally fixed manner to the output element 7. On the side opposite the guide slot 18, the output element 7 forms a plurality of driving flanks 36, which can interact with the driver 37 when the latter has been brought into the space between the driving flanks 36 by an axial displacement.

[0048] The locking cylinder works as follows: In a normal position, which Figures 19 to 21 and 25 and 26, no torque is exerted on 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 output element 7, is rotationally fixedly coupled to the closing element 14, so that the closing element 14 can only be rotated if the locking elements 4, 11 have previously been moved into a release position. The output element 7 is thus permanently connected to the closing element 14 in a rotationally fixed manner.

[0049] In this operating position, the locking element 4 is acted upon by the control pin 5 in the direction of the closing member 14 such that the locking projection 11' engages in one of the many locking recesses 16 of the locking element 4. In these locking positions, the locking element 4, the transmission element 33, and the output element 7 are connected in a rotationally fixed manner to the housing 9. The actuator 2 is also connected in a rotationally fixed manner to the housing 9 in this position.

[0050] If a torque is applied to 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 locking element 4, so that the locking projection 11' is released from the locking recess 16. As a result, the locking element 4 and the other elements non-rotatably coupled to the locking element 4, in particular the output element 7, the transmission element 33, and the actuator 2, can be rotated further.

[0051] In order to operate the locking cylinder with a key inserted into the keyway 42, the locking elements 4, 11 must first be disengaged. For this purpose, a transmission member 41 is provided, which is supported on the driver 40 by a compression spring 39. The transmission member 41 is supported on the extension 35 of the transmission member 33. A compression spring 38 applies force to the driver 40 against the driver 37, so that when the key is not inserted into the keyway 42, the driver 40 does not create a rotationally fixed connection between the cylinder core 44 and the locking member 14. When the key is not inserted, the locking member 14 is thus rotationally fixedly connected to the housing 9 via the locking elements 4, 11.

[0052] When the key is inserted into the keyway 42, this rotationally fixed connection between the locking member 14 and the housing 9 is released by displacing the locking element 4 in the axial direction, so that the locking projection 11' leaves the locking recess 16. Upon insertion of the key, the key tip acts on the transmission member 41 and displaces it in the axial direction. This results in the transmission member 41 acting against the end face of the extension 35 of the transmission member 33, and the latter is displaced in the axial direction. At the same time, the locking element 4 is also displaced in the axial direction such that the locking projection 11' emerges from the locking recess 16, thus removing the rotational inhibition of the locking member 14. During this axial displacement of the key, the driver 40 couples the cylinder core 44 to the locking member 14 in a rotationally fixed manner, so that the locking member 14 can be rotated by turning the key.

[0053] If the key is subsequently withdrawn from the keyway 42 of the cylinder core 44, the transmission member 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 locking member 14. The compression spring 6, which was tensioned during the axial displacement of the transmission member 33, relaxes, so that the locking element 4 is also returned to the locking position.
