Description

TECHNICAL FIELD

The present invention relates to a lock cylinder arrangement according to claim 1, a cylinder lock comprising such a lock cylinder arrangement according to claim 14, and a method for producing a lock cylinder arrangement according to claim 15.

STATE OF THE ART

Locking cylinder arrangements comprising a locking cylinder device, a rotary knob device with a rotary knob and a coupling device for engaging and disengaging the rotary knob device are known from the prior art, in particular from EP 2 287 423 A2 and the FR 2 742 469 A1 . A common problem with existing coupling devices is the fact that a spring is preloaded axially via a key. This leads to pressure on the key, which leads to ergonomic problems and even blockages, as the pressure on the key pushes the coding bolts outwards. Another disadvantage of the previous coupling devices is the required precise positioning of the rotary knob device relative to the lock cylinder device so that the spring forces of the spring of the lock cylinder device and the spring of the rotary knob device match. Otherwise, the coupling device can block, whereby turning is no longer possible, or the coupling device cannot couple and would always rotate freely.

PRESENTATION OF THE INVENTION

It is an object of the present invention to provide a lock cylinder arrangement which overcomes the disadvantages of the prior art. In particular, it is a task to provide a lock cylinder arrangement that is easy to assemble permitted and ensures reliable and stable operation.

This object is achieved by a locking cylinder arrangement according to claim 1. A locking cylinder arrangement is therefore specified which has a rotary knob device, locking cylinder device, a locking bit and a coupling device. The term “turn knob” is also known to those skilled in the art as “turn knob”. The same applies to the term “lock beard”, which is also known to those skilled in the art as “cam”. The rotary knob device comprises a rotary knob stator and a rotary knob rotor rotatably mounted in the rotary knob stator. The lock cylinder device comprises a lock cylinder stator and a lock cylinder rotor rotatably mounted in the lock cylinder stator. The locking bit is rotatably mounted with respect to the rotary knob device and the lock cylinder device. The coupling device extends along a longitudinal axis and can be brought into at least one engaged state and one disengaged state. The coupling device comprises a lock cylinder rotor coupler, a rotary knob rotor coupler rotatably mounted with respect to at least a first direction of rotation, a lock bit coupler, and at least one engagement element. The coupling device can be coupled or coupled to the lock cylinder rotor via the lock cylinder rotor coupler. The coupling device can further be coupled or coupled to the rotary knob rotor via the rotary knob rotor coupler. In addition, the coupling device can be coupled or is coupled to the locking bit via the locking bit coupler. The coupling device can be transferred from the engaged state to the disengaged state by rotating the rotary knob-rotor coupler with respect to the first direction of rotation. When engaged, the engagement element engages with the lock cylinder rotor coupler. In the disengaged state, the engagement element is out of engagement with the lock cylinder rotor coupler, so that the lock bit coupler can be rotated relative to the lock cylinder rotor coupler in the disengaged state.

This means that the engagement element can be disengaged from the lock cylinder rotor coupler by rotating the rotary knob rotor coupler with respect to the first direction of rotation. The coupling device is then in the disengaged state. When the coupling device is disengaged, the lock cylinder rotor coupler is preferably non-rotatable or fixedly mounted in the lock cylinder device when the rotary knob rotor coupler rotates. In other words, the coupling device according to the invention allows the rotary knob device to be actuated without the locking cylinder device being actuated.

Furthermore, it is preferred that the lock cylinder rotor coupler is rotatable with respect to the coupling device both in the disengaged and in the engaged state. Or to put it another way, rotation of the lock cylinder rotor coupler is preferably not prevented by the coupling device. Instead, it is preferred that rotation of the lock cylinder rotor coupler is permitted or prevented by the lock cylinder device. In particular, it is preferred that rotation of the lock cylinder rotor coupler with respect to the first direction of rotation and with respect to a second direction of rotation running opposite to the first direction of rotation is made possible when an authorized key is accommodated in the lock cylinder device. Furthermore, it is preferred that rotation of the lock cylinder rotor coupler with respect to the first direction of rotation and with respect to the second direction of rotation is impossible in the absence of an authorized key, or in other words is in a locked state.

The locking cylinder rotor coupler, the locking bit coupler and the locking bit are preferably designed such that a rotation of the locking cylinder rotor coupler with respect to the first direction of rotation and with respect to the second direction of rotation results in a rotation of the locking bit coupler and consequently of the locking bit with respect to these directions of rotation effects.

It is further preferred that the lock cylinder rotor coupler, the rotary knob rotor coupler, and the lock bit coupler are designed for a common rotation with respect to the first direction of rotation and/or a common rotation with respect to the second direction of rotation. Particularly preferably, the locking cylinder rotor coupler, the rotary knob rotor coupler, and the locking bit coupler are designed such that when the coupling device is engaged, power transmission from the locking cylinder rotor coupler to the locking bit coupler is made possible. This transmission is preferably made possible by the at least one engagement element which, when the coupling device is engaged, connects the locking cylinder rotor coupler to the locking bit coupler in a rotationally fixed manner. The release of this connection is preferably made possible by transferring the coupling device from its engaged state to its disengaged state, particularly preferably by rotating the rotary knob-rotor coupler relative to the locking bit coupler, whereby a rotation of the rotary knob-rotor coupler and the Lock bit coupler compared to the lock cylinder rotor coupler is made possible.

This means that the locking cylinder device is preferably always coupled to the locking bit. To put it another way, the locking bit is not mounted so that it can rotate freely. Furthermore, the lock cylinder device is preferably always coupled to the rotary knob device, with actuation of the rotary knob device disengaging the lock cylinder device. Consequently, the coupling device according to the invention has no interactions with the key itself. That is, and unlike the existing coupling devices, where a spring is preloaded axially over the key, the coupling device according to the invention does not cause any axial forces on a key received in the lock cylinder device. Consequently, with the lock cylinder arrangement according to the invention, no pressure is exerted on a key, thereby avoiding ergonomic problems or even blockages. A further advantage of the locking cylinder arrangement according to the invention lies in the length independence of the coupling device - this means that the same coupling device can be used for both a so-called Swiss profile and a so-called EU profile. In addition, the lock cylinder arrangement according to the invention is a self-contained arrangement and is not dependent on third-party parts. That is, and in contrast to the existing coupling devices, the coupling device according to the invention does not require precise positioning of the lock cylinder device with respect to the rotary knob device, thereby facilitating the assembly of the lock cylinder arrangement. Blocking of the clutch device or failure to engage the clutch device is also avoided with the clutch device according to the invention, which ensures reliable and stable operation. The locking cylinder arrangement according to the invention also has a short overall length compared to the existing locking cylinder arrangements. As a result, the rotary knob device can be guided longer, thereby increasing stability. A further advantage of the coupling device according to the invention is that the locking bit is not freely rotating due to the permanently coupled locking cylinder device (which cannot be rotated in the absence of an authorized key). Or to put it another way, the locking bit is arranged in a fixed manner, as is the case with a regular double cylinder. Because the locking bit cannot rotate freely, the locking bit cannot simply be driven directly during a drilling attack. This ensures protection against drilling or makes access more difficult and means that the locking cylinder arrangement according to the invention has a high level of security against manipulation.

The knob-rotor coupler and the knob-rotor are preferably present as separate components, wherein the knob-rotor coupler and the knob-rotor can be coupled to one another. However, it is also conceivable that the rotary knob rotor coupler and the rotary knob rotor are formed in one piece, with the rotary knob rotor coupler and the rotary knob rotor being coupled to one another.

The same can be said for the lock cylinder rotor coupler and the lock cylinder rotor, which are preferably present as separate components and can therefore be coupled, but can also be designed in one piece and can therefore be coupled.

The rotary knob device can further comprise a housing, with the rotary knob stator being mounted in the housing. The housing and the rotary knob stator are preferably components designed separately from one another. However, it is also conceivable that the housing and the rotary knob stator are formed in one piece. In this case, the housing can be seen as a rotary knob stator, with the rotary knob rotor being rotatably mounted in the housing.

The same can be said for the lock cylinder device, which can further comprise a housing and the lock cylinder stator is mounted in the housing. The housing and the lock cylinder stator can in turn preferably be components designed separately from one another. Here too, however, it is just as conceivable that the housing and the lock cylinder stator are designed in one piece, with the housing being seen as a lock cylinder stator, and with the lock cylinder rotor being rotatably mounted in the housing.

The rotary knob-rotor coupler is preferably rotatably mounted about a second direction of rotation that runs opposite to the first direction of rotation.

It is further preferred that a through opening extends along the longitudinal axis from the proximal end to the distal end of the body. In the region of the distal end, the body preferably has a coupling structure which is designed for coupling with the rotary knob rotor or with a rotor extension element, so that rotation of the rotary knob rotor or the rotor extension element onto the rotary knob rotor -Coupler is transferable. The knob device may include one or more rotor extension elements.

The lock bit coupler preferably comprises a substantially cylindrical body having a proximal end and a distal end and preferably a through opening which extends through the body from the proximal end to the distal end along the longitudinal axis.

The locking structure preferably projects distally from the locking bit coupler. It is further preferred that the locking bit coupler, in particular its body, is at least partially accommodated in the through opening of the rotary knob rotor coupler. The locking structure of the lock cylinder rotor coupler preferably also projects at least partially through the through opening of the rotary knob rotor coupler. Particularly preferably, a distal region of the locking structure of the locking cylinder rotor coupler projects distally from the body of the rotary knob rotor coupler.

The coupling device preferably comprises at least one securing element which secures the components against axial displacement along the longitudinal axis. The securing element is, for example, a snap ring, which can be fastened to the locking structure in the area of the locking structure protruding from the body of the rotary knob-rotor coupler.

Furthermore, it is preferred that the lock cylinder rotor coupler and the lock cylinder rotor are connected to one another in a rotationally fixed manner, so that a rotation of the lock cylinder rotor with respect to the first direction of rotation results in a rotation of the lock cylinder rotor coupler with respect to the first direction of rotation and / or so that a rotation of the lock cylinder rotor with respect to the second direction of rotation leads to a rotation of the lock cylinder rotor coupler with respect to the second direction of rotation. If the lock cylinder device has one or more rotor extension elements, the lock cylinder rotor coupler is preferably connected to the lock cylinder rotor in a rotationally fixed manner via these rotor extension elements, with the rotor extension elements also being connected in a rotationally fixed manner to the lock cylinder rotor coupler and the lock cylinder rotor are connected.

Furthermore, it is preferred that the rotary knob rotor coupler and the rotary knob rotor are connected to one another in a rotationally fixed manner, so that a rotation of the rotary knob rotor with respect to the first direction of rotation results in a rotation of the rotary knob rotor coupler with respect to the first direction of rotation and/or such that a rotation of the rotary knob rotor with respect to the second direction of rotation leads to a rotation of the rotary knob rotor coupler with respect to the second direction of rotation. If the rotary knob device has one or more rotor extension elements, the rotary knob-rotor coupler is preferably connected in a rotationally fixed manner to the rotary knob rotor via these rotor extension elements, with the rotor extension elements also being non-rotatably connected to the rotary knob-rotor coupler and the rotary knob rotor are connected.

Furthermore, it is preferred that the locking bit coupler and the locking bit can be coupled to one another in such a way that a rotation of the locking bit coupler with respect to the first direction of rotation results in a rotation of the locking bit with respect to the first direction of rotation and/or such that a rotation of the locking bit coupler with respect to the second direction of rotation leads to a rotation of the lock bit with respect to the second direction of rotation.

When the coupling device is engaged or disengaged, the rotatability of these components preferably behaves as follows.

The coupling device is preferably further designed such that rotation of the rotary knob-rotor coupler with respect to the first direction of rotation and with respect to the second direction of rotation is possible both in the engaged state and in the disengaged state of the coupling device. The coupling device is preferably further designed such that a rotation of the locking bit coupler and thus of the locking bit is possible in the event of a rotation of the rotary knob rotor coupler with respect to the first direction of rotation and the second direction of rotation both in the engaged state and in the disengaged state of the coupling device .

The rotary knob rotor coupler and/or the locking cylinder rotor coupler and/or the locking bit coupler are preferably non-displaceable with respect to the longitudinal axis and/or non-displaceable with respect to a radial axis.

The engagement element is preferably radially displaceable with respect to a radial axis and in particular during a transition of the coupling device from the engaged state to the disengaged state and/or from the disengaged state to the engaged state. Additionally or alternatively, the engagement element is preferably immovable with respect to the longitudinal axis.

The radial axis is perpendicular to the longitudinal axis of the coupling device. When the coupling device is engaged, a radial distance between the engagement element and the longitudinal axis is preferably smaller than a radial distance when the coupling device is disengaged. Or to put it another way, the engagement element preferably moves radially outwards during a transition of the coupling device from the engaged state to the disengaged state in the event of a rotation of the rotary knob rotor coupler, or radially inwards when the coupling device transitions from the disengaged state to the engaged state .

Alternatively, it is also conceivable that the engagement element is designed to be axially displaceable with respect to the longitudinal axis. Particularly preferably, the engagement element is axially displaceable with respect to the longitudinal axis during a transition of the coupling device from the engaged state to the disengaged state and/or from the disengaged state to the engaged state.

The lock cylinder arrangement preferably comprises two or more engagement elements. Two or more of these engagement elements are preferably arranged offset from one another with respect to the longitudinal axis. Additionally or alternatively, an arrangement of two or more engagement elements has rotational symmetry with respect to rotation about a rotation axis D of 1.

A rotational symmetry of 1 means that the engagement element or elements can only be converted into themselves when rotated through 360°. The axis of rotation preferably corresponds to the axis of rotation mentioned above, i.e. the axis of rotation running parallel to the longitudinal axis of the coupling device. Or to put it another way, the engagement elements are not arranged symmetrically with respect to the longitudinal axis of the coupling device.

The lock cylinder rotor coupler preferably has at least one recess. When engaged, the engagement element is preferably at least partially accommodated in this recess. Additionally or alternatively, the engagement element is preferably removed from this recess in the disengaged state.

When engaged, the engagement element preferably engages with the lock bit coupler. Additionally or alternatively, the engagement element is in disengaged state is preferably engaged with the locking bit coupler. Additionally or alternatively, the locking bit coupler preferably has at least one recess, the engagement element being at least partially accommodated in this recess in the engaged state and/or in the disengaged state.

When engaged, the engagement element is preferably disengaged from the rotary knob-rotor coupler. Additionally or alternatively, the engagement element is preferably in engagement with the rotary knob-rotor coupler in the disengaged state. Additionally or alternatively, the rotary knob-rotor coupler preferably has at least one recess, the engagement element being at least partially accommodated in this recess in the disengaged state and/or being removed from this recess in the engaged state.

As mentioned earlier, the engagement element is preferably designed for radial displacement. It is further preferred that the locking cylinder rotor coupler is at least partially mounted in the locking bit coupler and the locking bit coupler is in turn at least partially mounted in the rotary knob rotor coupler. These components are now preferably designed and arranged in such a way that when the coupling device is transferred from its engaged state to the disengaged state in the event of a rotation of the rotary knob rotor coupler with respect to the first direction of rotation, the engagement element comes out of the recess in the lock cylinder rotor coupler and in the lock bit coupler is increasingly moved radially outwards into the recess in the rotary knob rotor coupler. When the coupling device is disengaged, the engagement element is preferably completely removed from the recess of the lock cylinder rotor coupler and is located at least partially in the recess of the lock bit coupler and the rotary knob rotor coupler. These components are further preferably designed and arranged in such a way that the engagement element increasingly moves radially inwards into the recess in the locking cylinder rotor coupler during the transfer from the disengaged state to the engaged state from the recess in the rotary knob rotor coupler and in the lock bit coupler is postponed.

The recesses preferably have a shape corresponding to the engagement element. For example, the engagement element can have a round shape, with the recesses then preferably also having a round shape. The engagement element particularly preferably has the shape of a ball. Other shapes, such as a cylindrical shape, are of course just as conceivable.

A number of recesses in the lock bit coupler and/or a number of recesses in the lock cylinder rotor coupler preferably corresponds to a number of the engagement elements. It is further preferred that two or more recesses of the lock bit coupler and/or two or more recesses of the lock cylinder rotor coupler are arranged offset from one another with respect to the longitudinal axis and/or that an arrangement of these two or more recesses ensures rotational symmetry with respect to a rotation about an axis of rotation of 1. This means that, analogous to the arrangement of the engagement elements, the recesses of the locking cylinder rotor coupler or the locking bit coupler also preferably have a non-symmetrical arrangement.

A number of the recesses in the rotary knob-rotor coupler preferably corresponds to at least a number of the engagement elements. Preferably, the number of recesses in the rotary knob-rotor coupler is twice or twice the number of engagement elements. If, for example, three engagement elements are present, the rotary knob-rotor coupler preferably has six recesses. If the number of recesses in the rotary knob-rotor coupler corresponds to the number of engagement elements, the coupling device is designed to disengage in one direction of rotation, here in relation to the first direction of rotation. If the number of recesses in the rotary knob-rotor coupler is twice as large as the number of engagement elements, the coupling device is designed to disengage in both directions of rotation, here in relation to the first direction of rotation and the second direction of rotation.

The locking cylinder rotor coupler and/or the rotary knob rotor coupler and/or the locking bit coupler preferably comprises at least one execution element, so that the engagement element can be at least partially disengaged when guided along the execution element. Additionally or alternatively, the lock cylinder rotor coupler and/or the rotary knob rotor coupler and/or the lock bit coupler preferably comprises at least one insertion element, so that the engagement element can be at least partially brought into engagement while guided along the insertion element.

This means that the engagement and disengagement of the engagement element is preferably carried out in a guided manner, namely by guiding the engagement element along insertion elements and execution elements. The execution element(s) and/or the insertion element(s) are preferably around the surfaces or at least areas thereof delimiting the recess of the lock cylinder rotor coupler or the rotary knob rotor coupler or the lock bit coupler.

It is preferred that the engagement element is guided along the execution element of the lock cylinder rotor coupler and is disengaged from the lock cylinder rotor coupler when the rotary knob rotor coupler rotates with respect to the first direction of rotation of more than 0°, in particular a rotation in a range of approximately 1° to 60°, particularly preferably a rotation in a range of approximately 30° to 55°. The engagement of the engagement element with the lock cylinder rotor coupler, guided along the insertion element of the lock cylinder rotor coupler, preferably takes place when the rotary knob rotor coupler rotates with respect to the first direction of rotation of more than 350 °, in particular when rotating in one Range from about 350° to 380°, particularly preferably in a range from about 374° to 378°. These rotations refer to an untwisted state of the rotary knob-rotor coupler. The non-twisted state of the rotary knob-rotor coupler can also be referred to as the basic position of the coupling device. So a state in which the rotary knob device has not been operated by a user. A twisted state of the knob-rotor coupler therefore corresponds to a state in which the knob device has been operated by a user, preferably by rotating a knob of the knob device with respect to the first direction of rotation.

As will be explained in more detail below in connection with the stop elements, a rotation of the rotary knob rotor coupler can be transferred to the locking bit coupler. When the rotary knob rotor coupler is rotated with respect to the first direction of rotation, the locking bit coupler is therefore also rotated, with the engagement element guided along the execution element of the lock cylinder rotor coupler being disengaged from the lock cylinder rotor coupler when the lock cylinder rotor coupler is rotated Locking bit coupler with respect to the first direction of rotation of more than 0°, in particular with a rotation in a range of approximately 1° to 30°, particularly preferably with a rotation in a range of approximately 1° to 25°. The engagement of the engagement element with the lock cylinder rotor coupler, which is guided along the insertion element of the lock cylinder rotor coupler, preferably takes place when the lock bit coupler rotates with respect to the first direction of rotation of more than 320 °, in particular when rotating in a range of about 320° to 360°, particularly preferably in a range of about 330° to 360°. These rotations relate This means that the locking bit coupler is twisted compared to its untwisted state.

It is further preferred that the engagement element, guided along the insertion element of the rotary knob-rotor coupler, engages with the rotary knob-rotor coupler when the rotary knob-rotor coupler rotates with respect to the first direction of rotation of more than 0°, in particular at a rotation in a range of approximately 5° to 60°, particularly preferably a rotation in a range of approximately 10° to 55°. The disengagement of the engagement element with the rotary knob-rotor coupler, guided along the execution element of the rotary knob-rotor coupler, preferably takes place when the rotary knob-rotor coupler rotates with respect to the first direction of rotation of more than 350 °, in particular in a range of 350 ° to 380°, particularly preferably in a range of approximately 374° to 378°.

As mentioned before, when the rotary knob-rotor coupler is rotated, the locking bit coupler is also rotated, with the engagement element guided along the insertion element of the rotary knob-rotor coupler engaging with the rotary knob-rotor coupler when the locking bit is rotated -Coupler with respect to the first direction of rotation of more than 0 °, in particular with a rotation in a range of approximately 1 ° to 30 °, particularly preferably with a rotation in a range of approximately 1 ° to 25 °. The disengagement of the engagement element with the rotary knob-rotor coupler, which is guided along the execution element of the rotary knob-rotor coupler, preferably takes place when the locking bit coupler rotates with respect to the first direction of rotation of more than 320 °, in particular in a range from 320 ° to 360°, particularly preferably in a range of approximately 330° to 360°.

The disengagement of the engagement element with the lock cylinder rotor coupler is preferably carried out guided along the execution element of the lock bit coupler. Particularly preferably, the engagement element is brought into engagement with the rotary knob rotor coupler, guided along the insertion element of the lock bit coupler. This execution element and insertion element of the lock bit coupler are preferably one and the same element. This element can therefore also be referred to as the first on-off guide element of the locking bit coupler. Furthermore, it is preferred that the engaging element is brought into engagement with the lock cylinder rotor coupler guided along the insertion element of the lock bit coupler. Disengaging the engagement member with the knob-rotor coupler preferably takes place guided along the execution element of the locking bit coupler. This element is preferably one and the same element. This element can therefore be referred to as a second on-off guide element. The first on-off guide element and the second on-off guide element are preferably different elements from one another.

The locking bit coupler preferably has at least one stop element and the rotary knob rotor coupler preferably has at least one stop element, the stop elements forming a stop when the rotary knob rotor coupler rotates with respect to the first direction of rotation, so that the locking bit coupler also is rotated with respect to the first direction of rotation.

The stop element of the locking bit coupler is preferably an element that projects radially from an outer surface of the locking bit coupler, in particular from the body of the locking bit coupler. The stop element of the rotary knob-rotor coupler is preferably an element that projects axially from the rotary knob-rotor coupler. In particular, the stop element of the rotary knob-rotor coupler extends axially, or with respect to the longitudinal axis of the coupling device, outwards from the proximal end of the rotary knob-rotor coupler. As already mentioned earlier, the locking bit coupler is preferably at least partially accommodated in the rotary knob rotor coupler. In this state, the stop elements are arranged relative to one another in such a way that, in the event of rotation of the rotary knob-rotor coupler, they abut against one another with respect to the first direction of rotation and form a stop. This transfers the rotation of the rotary knob rotor coupler to the locking bit coupler. It is preferred that the locking bit coupler has two or more stop elements. Analogously, it is preferred that the rotary knob-rotor coupler also has two or more stop elements.

The rotary knob-rotor coupler preferably comprises at least one fixing element. The fixing element is preferably designed to fix the engagement of the engagement element with the lock cylinder rotor coupler in the engaged state. A fixation of the engagement element by the fixing element can preferably be canceled by rotating the rotary knob-rotor coupler with respect to the first direction of rotation.

That is, the fixing element prevents loosening of the engagement between the engagement element and the lock cylinder rotor coupler in the absence of rotation of the Rotary knob-rotor coupler with respect to the first direction of rotation. The fixing element is preferably arranged on an inner surface of the rotary knob rotor coupler facing the through opening and is particularly preferably formed by a region of the inner surface. Particularly preferably, the fixing element is formed by the area of the inner surface, which is arranged between two recesses in the rotary cylinder rotor body. In other words, the fixing element is an element that projects radially inwards.

In the non-twisted state of the rotary knob rotor coupler, the fixing element prevents the engagement element from moving out of the recess of the lock cylinder rotor coupler. In the event of a rotation of the rotary knob rotor coupler, however, the fixing element is also rotated accordingly and moved away from the engagement element, whereupon the engagement element can move out of the recess in the lock cylinder rotor coupler.

The coupling device preferably further comprises at least one restoring element, wherein the restoring element is designed to form a restoring force on the rotary knob-rotor coupler.

The restoring force is preferably such that the rotary knob-rotor coupler is transferred to the non-twisted state in the absence of a rotational force relative to the locking bit coupler or remains in the non-twisted state.

This is sometimes important because otherwise, when using the locking cylinder device with a key, the rotary knob-rotor coupler would not rotate due to friction and inertia and this would result in a twist between the rotary knob-rotor coupler and the locking bit coupler, which would result in this This results in a decoupling process being started and the locking cylinder device is no longer coupled to the locking bit coupler and would spin. The restoring element therefore ensures that the rotary knob rotor coupler is always at the same angle, preferably at a 0° angle, to the locking bit coupler. Therefore, a pretensioning force on the restoring element in the basic position, or in other words, for the rotary knob-rotor coupler to remain in the non-twisted state in the absence of a rotational force, is also preferred. To put it another way, it is preferred that the restoring element exerts a restoring force on the rotary knob-rotor coupler even in the non-twisted state of the rotary knob-rotor coupler. In particular, it is preferred that a restoring force of the restoring element in the untwisted state of the rotary knob-rotor coupler is smaller than a restoring force of the restoring element in the twisted state of the rotary knob-rotor coupler.

The restoring element is preferably at least partially mounted in the rotary knob rotor coupler and in the locking bit coupler.

The restoring element is preferably a spring element such as a torsion spring. However, other spring elements such as a spring plate are just as conceivable. In this case the restoring force is a spring force. However, other restoring elements are also conceivable, for example magnetic elements, where the restoring force is a magnetic force.

It is further preferred that the rotary knob-rotor coupler and the locking bit coupler each have a pressure element against which the restoring element is preferably increasingly pressed when the rotary knob-rotor coupler rotates. Particularly preferably, the pressure element of the rotary knob-rotor coupler is an area of the inner surface of the body, which faces the through opening of the rotary knob-rotor coupler, and the pressure element of the locking bit coupler is preferably an area of the inner surface of the body Body which faces the through opening of the lock bit coupler.

The locking bit coupler and the locking bit preferably each have at least one transmission element, the transmission elements forming a stop when the locking bit coupler rotates with respect to the first direction of rotation and/or with respect to a second direction of rotation running opposite to the first direction of rotation, so that the locking bit moves along is rotated in the first and/or second direction of rotation.

This means that the transmission elements are preferably designed to transmit the torque from the locking bit coupler in both directions of rotation to the locking bit. The transmission element of the locking bit coupler is preferably an element that projects radially from the body of the locking bit coupler. An embodiment of the transmission element of the locking bit and an embodiment of the transmission element of the locking bit coupler are preferably designed to be complementary to one another and/or for a positive connection.

Particularly preferred is the design of the transmission element of the locking bit, preferably such that it forms an exception that is complementary to the transmission element of the locking bit coupler and can thus transmit the torque in a form-fitting manner in both directions of rotation.

The lock cylinder arrangement preferably further comprises a rotary knob, which is connected to the rotary knob rotor. When the lock cylinder arrangement is installed in a cylinder lock in a door, the rotary knob device and consequently the rotary knob is preferably located on the inside of the building or living space, while the lock cylinder device is preferably located on the outside of the building or living space.

It is further preferred that the lock cylinder arrangement has further components, as are already known in conventional lock cylinder arrangements. For example, the locking cylinder device of the locking cylinder arrangement according to the invention can also have tumblers on the cylinder, which interact with mechanical coding of a key and allow the locking cylinder device to be unlocked in the case of an authorized key, etc. However, mechatronic locking cylinder devices are also conceivable, whereby an electrically controlled actuator would be provided to lock the locking cylinder device.

In a further aspect, a cylinder lock comprising a lock cylinder arrangement as described above is specified.

Explanations in connection with the lock cylinder arrangement apply analogously to a cylinder lock comprising the lock cylinder arrangement and vice versa.

In a further aspect, a method for producing a lock cylinder arrangement for a cylinder lock is specified. The method comprises the steps of i) providing a rotary knob device comprising a rotary knob stator and a rotary knob rotor rotatably mounted in the rotary knob stator, ii) providing a locking cylinder device comprising a locking cylinder stator and a rotatably mounted in the locking cylinder stator Locking cylinder rotor, iii) providing a locking bit which is rotatably mounted with respect to the rotary knob device and the locking cylinder device, and iv) providing a Coupling device. The coupling device extends along a longitudinal axis and can be brought into at least one engaged state and one disengaged state. The coupling device comprises a lock cylinder rotor coupler, a rotary knob rotor coupler rotatably mounted with respect to at least a first direction of rotation, a lock bit coupler, and at least one engagement element. The coupling device can be coupled to the lock cylinder rotor via the lock cylinder rotor coupler. The coupling device can be coupled to the rotary knob rotor via the rotary knob rotor coupler. The coupling device can be coupled to the locking bit via the locking bit coupler. The coupling device can be transferred from the engaged state to the disengaged state by rotating the rotary knob-rotor coupler with respect to the first direction of rotation. When engaged, the engagement element engages with the lock cylinder rotor coupler. In the disengaged state, the engagement element is out of engagement with the lock cylinder rotor coupler, so that the lock bit coupler can be rotated relative to the lock cylinder rotor coupler in the disengaged state.

In particular, it is a method for producing a lock cylinder arrangement as described above. Explanations in connection with the lock cylinder arrangement therefore apply analogously to the method for producing the lock cylinder arrangement and vice versa.

DESCRIPTION OF PREFERRED EMBODIMENTS

Aspects of the lock cylinder arrangement according to the invention will now be based on the Figures discussed.

Like from the Figures 1 to 8 As can be seen, the locking cylinder arrangement 1 comprises a rotary knob device 2 comprising a rotary knob stator 29 and a rotary knob rotor 10 which is rotatably mounted in the rotary knob stator 29 about an axis of rotation D, a locking cylinder device 3 comprising a locking cylinder stator 11 and a rotatable about the axis of rotation D in the lock cylinder stator 11 mounted lock cylinder rotor 12, a locking bit 4, which is rotatably mounted about the axis of rotation D with respect to the rotary knob device 2 and the lock cylinder device 3, and a coupling device 5. The Figures 1 to 4 show a lock cylinder arrangement 1 according to the Swiss profile, while the Figures 5 to 8 represent a lock cylinder arrangement 1 comprehensive according to the EU profile. The lock cylinder arrangements of these figures also differ in the absence ( Figures 1-2 and 5-6 ) or the presence ( Figures 3-4 and 7-8 ) of rotor extension elements 30, 31. The coupling devices 5 are the same for both profiles and in the presence and absence of rotor extension elements 30, 31. This means that the coupling device 5 according to the invention can be used for both a Swiss profile and an EU profile.

The remaining components of the lock cylinder arrangements 1 shown here are commercially available and well-known components. The lock cylinder arrangement 1 further comprises a rotary knob 32, which is connected to the rotary knob rotor 10, a housing 33, 34 for receiving the rotary knob stator 29 or the lock cylinder stator 11, and fastening means 35, 36 such as fastening screws . Using the fastening screws 35, 36, the lock cylinder stator 11 or the rotary knob stator 29 are screwed to the respective housing 34, 33 and the rotary knob 32 to the rotary knob rotor 10.

The coupling device 5 according to the invention will be explained in detail below. At this point and with reference to the Figures 2 , 4 , 6 and 8th However, attention is drawn to the advantage of the coupling device 5 according to the invention, which does not cause any axial forces on a key 37 received in the locking cylinder device. In particular, there are no interactions whatsoever between the coupling device 5 and a recorded key 37. As a result, no key extensions or the like are necessary.

How good looking Figure 9 As can be seen, the coupling device 5 extends along a longitudinal axis L and can be brought into at least one engaged state and one disengaged state. When the coupling device 5 is installed, the longitudinal axis L of the coupling device 5 runs parallel to a longitudinal axis L 'of the locking cylinder arrangement. The coupling device 5 comprises a locking cylinder rotor coupler 6, a rotary knob rotor coupler 7 which is rotatably mounted with respect to a first direction of rotation d1, a locking bit coupler 8, and at least one engagement element 9. In the examples shown here, the coupling device comprises three engagement elements 9, 9a, 9b, which here each have the shape of a ball. The rotary knob-rotor coupler 7, the locking cylinder rotor coupler 6, and the locking bit coupler 8 are rotatably mounted about the axis of rotation D with respect to a first direction of rotation d1 and a second direction of rotation d2 running opposite to the first direction of rotation d1. The axis of rotation D extends through the coupling device 5 and parallel to the longitudinal axis L of the coupling device.

In the examples shown, the rotary knob rotor coupler 7 and the rotary knob rotor 10 or the lock cylinder rotor coupler 6 and the lock cylinder rotor 12 are separately formed components which can be coupled to one another. It is important to understand that these components can also be present in one piece, i.e. in the form of a single element or individual piece. The locking cylinder arrangements 1 shown here also each include a rotary knob device 2 comprising a housing 33 and a locking cylinder device 3 comprising a housing 34, with the rotary knob stator 29 in the housing 33 of the rotary knob device 2 or the locking cylinder stator 11 in Housing 34 of the lock cylinder device 3 are stored. This means that in these examples these components are also present as separate components. However, it is also important to understand here that a one-piece training is just as conceivable. The coupling device 5 shown here further comprises a restoring element 27 and a spacer 38, the spacer 38 setting a radial distance between the restoring element 27 and the components of the coupling device 5. In connection with the Figures 9 , 19 and 22c to 30c Further explanations about the reset element 27 will be made later.

The coupling device 5 can be coupled to the lock cylinder rotor 12 via the lock cylinder rotor coupler 6 and to the rotary knob rotor 10 via the rotary knob rotor coupler 7. Furthermore, the coupling device 5 can be coupled to the locking bit 4 via the locking bit coupler 8. The lock cylinder rotor coupler 6, the rotary knob rotor coupler 7, and the locking bit coupler 8 are designed in such a way that when the coupling device 5 is engaged, power transmission from the locking cylinder rotor coupler 6 to the locking bit coupler 8 is made possible. This transmission is made possible by the engagement elements 9, 9a, 9b, which connect the locking cylinder rotor coupler 6 to the locking bit coupler 8 in a rotationally fixed manner when the coupling device 5 is engaged. This connection is released by transferring the coupling device 5 from its engaged state to its disengaged state by rotating the rotary knob rotor coupler 7 relative to the locking bit coupler 8, which results in a rotation of the rotary knob rotor coupler 7 and the locking bit. Coupler 8 compared to the lock cylinder rotor coupler 6 is made possible.

Like from the Figures 9 and 10 As can be seen, the lock cylinder rotor coupler 6 comprises a substantially cylindrical body 39 with a proximal end 40 and a distal end 41. In the area of the proximal end 39, a coupling structure 42 is provided, which has a coupling with the lock cylinder rotor 12 or with a rotor extension element 30 is permitted, so that a rotation of the lock cylinder rotor 12 or the rotor extension element 30 can be transferred to the lock cylinder rotor coupler 6. In particular, this coupling structure 42 is designed for a rotationally fixed connection to the lock cylinder rotor 12 or a rotor extension element 30. In the area of the distal end 41, a locking structure 43 is provided, which extends away from the distal end 41 of the body 39 along the longitudinal axis L. This locking structure 43 also has a substantially cylindrical shape. A cross section of the locking structure is smaller than a cross section of the body 39. The lock cylinder rotor coupler 6, in particular its body 39, here comprises three recesses 13, 13a, 13b. The recesses 13, 13a, 13b are designed to be complementary to the engagement elements 9, 9a, 9b and have the shape of circular openings. When the clutch device 5 is engaged, the engagement elements 9, 9a, 9b are at least partially accommodated in these recesses 13, 13a, 13b. When the clutch device 5 is disengaged, the engagement elements 9, 9a, 9b are removed from these recesses 13, 13a, 13b.

In the Figures 11 to 14 the locking bit coupler 8 is shown, which here also comprises a substantially cylindrical body 44 with a proximal end 45 and a distal end 46. It also has a through opening 47, which extends from the proximal end 45 to the distal end 46 along the longitudinal axis L through the body 44. Analogous to the locking cylinder rotor coupler 6, the locking bit coupler 8 also includes recesses 14, 14a, 14b, which are designed to be complementary to the engagement elements 9, 9a, 9b and here have the shape of circular openings. Both in the engaged state and in the disengaged state of the coupling device 5, the engagement elements 9 are at least partially accommodated in these recesses 14, 14a, 14b.

Like in the Figures 15 and 16 As can be seen, the rotary knob rotor coupler 7 also includes a substantially cylindrical body 48 with a proximal end 49 and a distal end 50. It also has a through opening 51 which extends along the longitudinal axis L from the proximal end 49 to the distal end 50 of the body 48 extends. In the area of the distal end 50, the body 48 also has a coupling structure 52, which is designed for a coupling with the rotary knob rotor 10 or with a rotor extension element 31, so that rotation of the rotary knob rotor 10 or the rotor Extension element 31 can be transferred to the rotary knob rotor coupler 7. In particular, this coupling structure 52 is designed for a rotation-proof connection with the rotary knob rotor 10 or a rotor extension element 31. Analogous to the locking bit coupler 8 and the locking cylinder rotor coupler 6, the rotary knob rotor coupler 7 also has three recesses 15, 15a, 15b on, see Figure 9 , wherein the engagement elements 9, 9a, 9b are at least partially accommodated in these recesses 15, 15a, 15b in the disengaged state of the coupling device 5 and are removed from these recesses 15, 15a, 15b in the engaged state of the coupling arrangement 5.

In the assembled state of the coupling device 5, as shown in the Figures 17 to 21 is shown, the lock cylinder rotor coupler 6, in particular its body 39 and the locking structure 43, is at least partially accommodated in the through opening 47 of the lock bit coupler 8. The locking structure 43 of the locking cylinder rotor coupler 6 protrudes distally from the locking bit coupler 8. In addition, the locking bit coupler 8, in particular its body 44, is at least partially accommodated in the through opening 51 of the rotary knob rotor coupler 7, the locking structure 43 of the locking cylinder rotor coupler 6 also being at least partially through the through opening 51 of the rotary knob. Rotor coupler 7 protrudes through and distally from the body 48 of the rotary knob rotor coupler 7.

Like especially in the Figures 9 and 20 As can be seen, the coupling device 5 further comprises a securing element 53, here in the form of a snap ring, which secures the components against axial displacement along the longitudinal axis L. The snap ring 53 is fastened to the locking structure 43 in the area of the locking structure 43 of the locking cylinder rotor coupler 6 protruding from the body 48 of the rotary knob rotor coupler 7. Consequently, the rotary knob rotor coupler 7, the lock cylinder rotor coupler 6 and the lock bit coupler 8 are mounted so that they cannot be moved with respect to the longitudinal axis L. These components are also mounted immovably with respect to a radial axis R, which runs perpendicular to the longitudinal axis L of the coupling device 5.

The coupling device 5 is preferably assembled as follows. In a first step, the lock cylinder rotor coupler 6 is inserted into the lock bit coupler 8. In a second step, the engagement elements 9, 9a, 9b are inserted into the recesses 14, 14a, 14b of the lock bit coupler 8. In a third step, the spacer 38 is inserted over the locking structure 43 of the lock cylinder rotor coupler 6. In a fourth step, the restoring element 27 is inserted into the rotary knob-rotor coupler 7. In a fifth step, the rotary knob rotor coupler 7, comprising the restoring element 27, is connected to the lock bit coupler 8 and the lock cylinder rotor coupler 6 accommodated therein. In a sixth step, the security element 53 is attached to the locking structure 43 of the lock cylinder rotor coupler 6.

As can be seen from the figures, the engagement elements 9, 9a, 9b are arranged offset from one another with respect to the longitudinal axis L. In addition, the engagement elements 9, 9a, 9b have rotational symmetry with respect to a rotation of the rotation axis D of 1, so they can only be converted back into themselves in the event of a rotation of 360 °. The recesses 13, 13a, 13b of the lock cylinder rotor coupler 6, the recesses 14, 14a, 14b of the lock bit coupler 8, and the recesses 15, 15a, 15b of the rotary knob rotor coupler 7 are analogous to the engagement elements 9 , 9a, 9b are each arranged offset from one another with respect to the longitudinal axis L and also have rotational symmetry with respect to a rotation about the rotation axis D of FIG. This asymmetrical design means that coupling is only possible at certain rotational positions of the rotary knob-rotor coupler 7.

In the examples shown, the engagement elements 9, 9a, 9b are relative to the longitudinal axis L is mounted immovably, but is radially displaceable with respect to the radial axis R and carries out a radial displacement along the radial axis R during a transition of the coupling device 5 from the engaged state to the disengaged state and from the disengaged state to the engaged state. This radial displaceability is demonstrated in particular by comparing the Figures 22a to 29c clear, which represents different coupling states of the coupling device 5. In particular, these figures show the disengagement of the lock cylinder device 3, specifically the lock cylinder rotor coupler 6, when the rotary knob rotor coupler 7 rotates about the axis of rotation D and with respect to the first direction of rotation d1.

Like from the Figures 22a to 29c As can be seen, the coupling device 5 can be transferred from the engaged state to the disengaged state by rotating the rotary knob rotor coupler 7 with respect to the first direction of rotation d1. In the coupled state of the coupling device 5, as in the Figures 20 and 22a to 22c is shown, the engagement elements 9, 9a, 9b are in engagement with the lock cylinder rotor coupler 6. In the uncoupled state of the coupling device 5, as shown, for example, in the Figures 24a to 26c is shown, the engagement elements 9, 9a, 9b are disengaged from the lock cylinder rotor coupler 6, so that the lock bit coupler 8 is rotatable relative to the lock cylinder rotor coupler 6 in the disengaged state. As can be seen from these figures, a radial distance between the engagement elements 9, 9a, 9b and the longitudinal axis L in the engaged state of the coupling device 5 is smaller than a radial distance in the disengaged state of the coupling device 5. As can also be seen in particular from Figures 22a , 23a and 24a As can be seen, the engagement elements 9, 9a, 9b are removed from the recesses 13, 13a, 13b in the lock cylinder when the coupling device 5 is transferred from its engaged state to the disengaged state in the event of a rotation of the rotary knob-rotor coupler 7 with respect to the first direction of rotation d1 -Rotor coupler 6 and the recesses 14, 14a, 14b in the lock bit coupler 8 are increasingly displaced radially outwards into the recesses 15, 15a, 15b in the rotary knob rotor coupler 7. When the coupling device 5 is disengaged, the engagement elements 9, 9a, 9b are completely removed from the recesses 13, 13a, 13b of the locking cylinder rotor coupler 6 and are located in the recesses 14, 14a, 14b of the locking bit coupler 8 and the recesses 15, 15a, 15b of the rotary knob rotor coupler 7, see e.g Figures 24a, 25a and 26a . When the coupling device 5 is transferred back to the engaged state, the engagement elements 9, 9a, 9b are removed from the recesses 15, 15a, 15b in the rotary knob rotor coupler 7 and the recesses 14, 14a, 14b in the lock bit coupler 8 increasingly shifted radially inwards again into the recesses 13, 13a, 13b in the lock cylinder rotor coupler 6, see for example Figures 27a, 28a and 29a .

The lock cylinder rotor coupler 6, the rotary knob rotor coupler 7, and the lock bit coupler 8 include execution elements 16, 17, 18, along which the engagement elements 9 are at least partially disengaged. The lock cylinder rotor coupler 6, the rotary knob rotor coupler 7 and the lock bit coupler 8 also each include insertion elements 19, 20, 21, along which the engagement elements 9 are at least partially brought into engagement. These execution elements 16, 17, 18 and insertion elements 19, 20, 21 are each the recesses 13-13b, 14-14b, 15-15b of the lock cylinder rotor coupler 6 or the rotary knob rotor coupler 7 or the locking bit coupler 8 delimiting surfaces or at least areas thereof.

The disengagement of the engagement elements 9, 9a, 9b, guided along the execution elements 16 of the locking cylinder rotor coupler 6, takes place here when the rotary knob rotor coupler 7 rotates with respect to the first direction of rotation d1 in a range of approximately 30° to 55° , please refer Figures 22a to 24c . These rotations refer to an untwisted state of the rotary knob-rotor coupler 7, as shown, for example, in Figures 17 to 22c is shown.

The engagement of the engagement elements 9, 9a, 9b with the rotary knob-rotor coupler 7, guided along the insertion element 21 of the rotary knob-rotor coupler 7, takes place here when the rotary knob-rotor coupler 7 rotates with respect to the first direction of rotation d1 Range from about 10° to 55°, see Figures 22a to 26c .

The disengagement of the engagement elements 9, 9a, 9b with the rotary knob-rotor coupler 7, which is guided along the execution element 18 of the rotary knob-rotor coupler 7, takes place here when the rotary knob-rotor coupler 7 rotates with respect to the first direction of rotation d1 in one Range from approximately 374° to 378°, see Figures 27a to 29c .

The engagement of the engagement elements 9, 9a, 9b with the lock cylinder rotor coupler 6, guided along the insertion elements 19 of the lock cylinder rotor coupler 6, takes place in a range when the rotary knob rotor coupler 7 rotates with respect to the first direction of rotation d1 from about 374° to 378°, see also Figures 27a to 29c .

The disengagement of the engagement elements 9, 9a, 9b with the lock cylinder rotor coupler 6 along the execution elements 17 of the lock bit coupler 8 as well as the engagement of the engagement elements 9, 9a, 9b guided along the insertion elements 20 of the lock bit coupler 8 with the rotary knob-rotor coupler 7 take place here along the same surfaces. These surfaces are therefore also referred to herein as the first on-off guide elements 22 of the locking bit coupler 8. Analogously, the engagement elements 9, 9a, 9b are brought into engagement with the lock cylinder rotor coupler 6 along the insertion elements 20 of the lock bit coupler 8 and the engagement elements 9, 9a, 9b are disengaged from the rotary knob rotor coupler 7 along the execution elements 17 of the locking bit coupler 8 along the same surfaces. These surfaces are therefore also referred to herein as second on-off guide elements 23.

Like from the Figures 9 , 19 and 22c to 30c As can be seen, the coupling device 5 further comprises a restoring element 27 in the form of a torsion spring. The restoring element 27 exerts a restoring force on the rotary knob-rotor coupler 7 in such a way that the rotary knob-rotor coupler 7 is transferred to the non-twisted state relative to the locking bit coupler 8 in the absence of a rotational force on the rotary knob-rotor coupler 7 or remains in an untwisted state. The restoring element 27 is stored in the rotary knob rotor coupler 7 and in the locking bit coupler 8. Like for example in Figure 9 As can be seen, the body 48 of the rotary knob-rotor coupler 7 includes an opening 54 through which the restoring element 27 can be inserted into the interior of the body 48, in particular into its through opening 51. Since the locking bit coupler 8 is at least partially inserted into the through opening 51 of the rotary knob rotor coupler 7, the restoring element 27 also comes into contact with the locking bit coupler 8. In particular, the restoring element 27 is in the distal position in the assembled state of the coupling device 5 Area of the locking bit coupler 8 stored. This distal region of the locking bit coupler 8 has the shape of a semicircular receptacle 55. Furthermore, the rotary knob-rotor coupler 7 and the locking bit coupler 8 each have a pressure element 56, 57, against which the restoring element 27 is increasingly pressed when the rotary knob-rotor coupler 7 rotates. The pressure element 56 of the rotary knob rotor coupler 7 is a region of the inner surface of the body 48 which faces the through opening 51 of the rotary knob rotor coupler 7. The pressure element 57 of the locking bit coupler 8 is also an area of the inner surface of the body 44, which faces the through opening 47 of the locking bit coupler 8. This is particularly evident from the Figures 22c , 23c , etc. out.

Like in particular from the Figures 22a and 22b As can be seen, the rotary knob-rotor coupler 7 comprises fixing elements 26, the fixing elements 26 being designed to fix the engagement of the engagement elements 9, 9a, 9b with the lock cylinder rotor coupler 6 in the engaged state. The fixing elements 26 are arranged on an inner surface of the rotary knob-rotor coupler 7 facing the through opening 51 of the rotary knob-rotor coupler 7 and are formed by a region of the inner surface. The fixing elements 26 are here each formed by the area of the inner surface, which is arranged between two recesses 15, 15a, 15b, ... of the rotary knob-rotor coupler 7.

The fixing elements 26 protrude radially inwards and come to rest on an outer surface of the engagement elements 9, 9a, 9b in the non-twisted state of the rotary knob rotor coupler 7, so that the engagement elements 9, 9a, 9b do not come out of the recess 13, 13a, 13b of the lock cylinder rotor coupler 6 can move out. In the event of a rotation of the rotary knob-rotor coupler 7, however, its fixing elements 26 are also rotated accordingly and thereby moved away from the engagement elements 9, 9a, 9b, whereupon the engagement elements 9, 9a, 9b move out of the recess 13, 13a, 13b in the lock cylinder -Rotor coupler 6 can move out, see e.g Figures 23a, 23b, 24a and 24b .

This means that the engagement elements 9, 9a, 9b can be disengaged from the lock cylinder rotor coupler 6 by rotating the rotary knob rotor coupler 7 with respect to the first direction of rotation d1. Then the coupling device 5 is in the disengaged state, as in, for example Figures 24a to 26c is shown. As can be seen from these figures, the asymmetrical arrangement of the engagement elements 9, 9a, 9b and the recesses 13, 13a, 13b of the lock cylinder rotor coupler 6, prevents the recesses 14, 14a, 14b of the lock bit coupler 8, and the recesses 15, 15a, 15b of the rotary knob-rotor coupler 7 re-engage as long as the rotational position of the rotary knob-rotor coupler 7 is not correct. Or to put it another way, the recesses 13-13b, 14-14b, 15-15b are only accessible to the engagement elements 9, 9a, 9b when the rotary knob-rotor coupler 7 is in a certain rotational position. Otherwise, the engagement elements 9, 9a, 9b abut against the body 39 of the lock cylinder rotor coupler 6, see e.g Figures 24a, 24b, 25a, 25b, 26a and 26b .

The Figures 27a to 28c show the coupling device 5 shortly before reaching it re-engaged state. The Figures 29a to 29c show the coupling device 5 in its re-engaged state. The coupling device 5 is transferred into its re-engaged state by the restoring force of the restoring element 27, here therefore by the spring preload, which is increasingly generated when the rotary knob-rotor coupler 7 is rotated with respect to the first direction of rotation d1. That is, the coupling device 5 is close to its original position, as shown in FIGS Figures 27a to 27c is shown, the locking bit coupler 8 is twisted back by the spring preload as soon as there is space, which results in the engagement elements 9, 9a, 9b being pushed back into the locking cylinder rotor coupler 6. This condition is in the Figures 28a to 28c shown. In this state, however, the coupling device 5 is not yet fully engaged. To do this, the user must leave the rotary knob-rotor coupler 7 free, with the remaining spring preload returning the rotary knob-rotor coupler 7 to the original position, i.e. to the basic position, with respect to the second direction of rotation d2. Only then is the coupling device 5 fully engaged again, see Figures 29a to 29c .

As just mentioned, the coupling device 5 is located Figures 29a to 29c in a basic state, i.e. an untwisted state of the rotary knob-rotor coupler 7 but also of the lock cylinder rotor coupler 6. If an authorized key 37 is now included in the lock cylinder device 3, the lock cylinder rotor coupler is connected in a rotationally fixed manner 6 with the remaining components of the coupling device 5 so that the entire coupling device 5 is rotated with respect to the first direction of rotation d1 and / or the second direction of rotation d2. Or to put it another way, when the lock cylinder rotor coupler 6 is rotated by turning an authorized key 37, the components of the coupling device 5 do not carry out any relative movements to one another, see Figures 30a to 30c .

The Figures 31 to 42 now show these processes in the case of a coupling device 5, which is connected to a locking cylinder device 3 and a rotary knob device 2.

From these figures it can also be seen that when the rotary knob-rotor coupler 7 is rotated by turning a rotary knob 32 ( Figures 31 to 36 ) or when the lock cylinder rotor coupler 6 is rotated by turning an authorized key 37 ( Figures 37 to 42 ) a rotation of the locking bit coupler 8 and the locking bit 4 is caused.

A rotation of the locking bit coupler 8 in the event of a rotation of the rotary knob 32 is caused by stop elements 25 of the turning knob rotor coupler 7, which form a stop with corresponding stop elements 24 of the locking bit coupler 8, see Figures 9 and 31 . The stop elements 24 of the locking bit coupler 8 are each elements that protrude radially from the outer surface of the locking bit coupler 8. The stop elements 25 of the rotary knob-rotor coupler 7 are elements which protrude axially from the rotary knob-rotor coupler 7 and which extend outwards from the proximal end 49 of the rotary knob-rotor coupler 7 with respect to the longitudinal axis L of the coupling device 5.

A rotation of the lock bit 4 is caused by the rotation of the lock bit coupler 8. For this purpose, the locking bit coupler 8 has a transmission element 28, which interacts with a corresponding transmission element of the locking bit 4. Like from the Figures 9 , 32 , 33 , 35 and 26 As can be seen, the transmission element 28 of the locking bit coupler 8 is an element that protrudes radially from the body 44 of the locking bit coupler 8.

As mentioned, they show Figures 37 to 42 an actuation of the lock cylinder device 1 by turning an authorized key 37s. Due to the rotation-proof connection, the entire coupling device 5 and consequently also the locking bit 4 are also rotated.
