Description

TECHNICAL AREA

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

Lock cylinder arrangements comprising a lock 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. A frequent problem with the existing coupling devices is the fact that a spring is prestressed axially using a key. This leads to pressure on the key, which leads to problems in terms of ergonomics and even blockages, since 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 may lock up preventing rotation, or the coupling device may not engage 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 an object to specify a lock cylinder arrangement which is easy to assemble allowed and ensures reliable and stable operation.

This object is achieved by a lock cylinder arrangement according to claim 1. A lock cylinder arrangement is therefore specified which has a rotary knob device, a lock cylinder device, a lock bit and a clutch device. The term "rotary knob" is also known to those skilled in the art as "rotary knob". The same applies to the term "lock bit", which is also known to those skilled in the art as "cam". The turning knob device comprises a turning knob stator and a turning knob rotor which is rotatably mounted in the turning knob stator. The lock cylinder device comprises a lock cylinder stator and a lock cylinder rotor rotatably mounted in the lock cylinder stator. The lock 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 clutch device comprises a lock cylinder rotor coupler, a rotary knob rotor coupler that is mounted rotatably with respect to at least a first direction of rotation, a lock bit coupler, and at least one engagement element. The clutch device can be coupled or is coupled to the lock cylinder rotor via the lock cylinder rotor coupler. The coupling device is further couplable or coupled to the knob rotor via the knob rotor coupler. In addition, the coupling device can be coupled or is coupled to the lock bit via the lock bit coupler. The clutch 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. In the coupled state, the engagement element engages with the lock cylinder rotor coupler. In the disengaged state, the engagement element is disengaged from 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 locking 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. In the disengaged state of the coupling device, the locking cylinder rotor coupler is preferably non-rotatably or fixedly mounted in the locking cylinder device when the rotary knob rotor coupler is rotated. 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 in the process.

Furthermore, it is preferred that the locking cylinder rotor coupler can be rotated with respect to the coupling device both in the disengaged and in the engaged state. In other words, 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 prohibited 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 opposite to the first direction of rotation is enabled 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 blocked state.

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

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. The lock cylinder rotor coupler, the rotary knob rotor coupler and the lock bit coupler are particularly preferably designed in such a way that when the clutch device is engaged, power can be transmitted from the lock cylinder rotor coupler to the lock bit coupler. This transmission is preferably made possible by the at least one engagement element which, in the engaged state of the coupling device, connects the lock cylinder rotor coupler to the lock 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 twisting the rotary knob rotor coupler relative to the lock bit coupler, which causes the rotary knob rotor coupler and the Lock bit coupler is made possible compared to the lock cylinder rotor coupler.

This means that the lock cylinder device is preferably always coupled to the lock bit. In other words, the lock bit is not freely rotatable. 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 axially pretensioned via the key, the coupling device according to the invention causes no axial forces on a key held in the lock cylinder device. Consequently, in the case of the locking cylinder arrangement according to the invention, no pressure is exerted on a key, as a result of which ergonomic problems or even blockages are avoided. A further advantage of the locking cylinder arrangement according to the invention lies in the length independence of the coupling device - the same coupling device can thus be used both for a so-called Swiss profile and for a so-called EU profile. In addition, the locking cylinder arrangement according to the invention is a self-contained arrangement and is not dependent on third-party parts. That is to say, 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, as a result of which the assembly of the lock cylinder arrangement is facilitated. Blocking of the clutch device or non-engagement of the clutch device is also avoided with the clutch device according to the invention, as a result of which it ensures reliable and stable operation. The lock cylinder arrangement according to the invention also has a short overall length compared to the existing lock cylinder arrangements. As a result, the turning knob device can be guided longer, thereby increasing stability. A further advantage of the coupling device according to the invention is that the lock bit is not freely rotating due to the permanently coupled lock cylinder device (which cannot be rotated in the absence of an authorized key). In other words, the lock bit is fixed, as is the case with a regular double cylinder. Due to the fact that the lock bit cannot be rotated freely, the lock bit cannot simply be driven directly in the event of a drilling attack. This ensures protection against drilling or makes access more difficult and means that the lock cylinder arrangement according to the invention has a high degree of protection against manipulation.

The knob-rotor coupler and the knob-rotor are preferably separate components, with the knob-rotor coupler and the knob-rotor being couplable to one another. However, it is also conceivable for the turning knob rotor coupler and the turning knob rotor to be designed in one piece, with the turning knob rotor coupler and the turning knob rotor being coupled to one another.

The same can be said for the locking cylinder rotor coupler and the locking 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 turning knob device may further comprise a housing, wherein the turning knob stator is supported in the housing. The housing and the rotary knob stator are preferably components that are designed separately from one another. However, it is just as conceivable that the housing and the rotary knob stator are designed 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 also include 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 that are 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 mounted so as to be rotatable about a second direction of rotation running opposite to the first direction of rotation. In addition or as an alternative to this, the locking cylinder rotor coupler and/or the locking bit coupler is preferably mounted such that it can rotate about the first direction of rotation and/or about the second direction of rotation.

The first direction of rotation and the second direction of rotation preferably run around a common axis of rotation. The axis of rotation extends through the coupling device and is preferably parallel to the longitudinal axis of the coupling device.

The locking cylinder rotor and/or the turning knob rotor and/or the locking bit are preferably mounted such that they can rotate about the first direction of rotation and/or about the second direction of rotation.

In addition or as an alternative to this, the lock cylinder rotor coupler is preferably at least partially accommodated in the lock bit coupler and/or at least partially in the rotary knob rotor coupler. In addition or as an alternative to this, the lock bit coupler is preferably at least partially accommodated in the rotary knob rotor coupler.

The knob-rotor coupler preferably includes a generally cylindrical body having a proximal end and a distal end. Furthermore, it is preferred that a through-opening extends along the longitudinal axis, starting 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 to the rotary knob rotor or to a rotor extension element, so that rotation of the rotary knob rotor or the rotor extension element on the rotary knob rotor -Coupler is transferrable. The turning knob device may include one or more rotor extension members.

The cam coupler preferably includes a generally cylindrical body having a proximal end and a distal end, and preferably a through hole extending through the body from the proximal end to the distal end along the longitudinal axis.

The key cylinder rotor coupler preferably comprises a generally cylindrical body having a proximal end and a distal end. In the area of the proximal end, a coupling structure is preferably provided, which allows a coupling with the locking cylinder rotor or with a rotor extension element, so that a rotation of the locking cylinder rotor or the rotor extension element can be transmitted to the locking cylinder rotor coupler. The lock cylinder device may include one or more rotor extension members.

In the region of the distal end, a locking structure is provided which extends away from the distal end of the body along the longitudinal axis. This locking structure also preferably has a substantially cylindrical shape. A cross section of Detent structure is preferably smaller than a cross-section of the body.

The lock bit coupler, the lock cylinder rotor coupler and the rotary knob rotor coupler are preferably components that are designed separately from one another. In the assembled state of the coupling device, the lock cylinder rotor coupler, in particular its body and the locking structure, is preferably at least partially accommodated in the through opening of the lock bit coupler. The locking structure preferably protrudes distally from the lock bit coupler. It is further preferred that the locking bit coupler, in particular its body, is at least partially accommodated in the passage opening of the rotary knob rotor coupler. The locking structure of the lock cylinder rotor coupler preferably likewise protrudes at least partially through the passage opening of the rotary knob rotor coupler. More preferably, a distal portion of the locking structure of the lock barrel rotor coupler projects distally from the body of the 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.

It is also preferred that the lock cylinder rotor coupler and the lock cylinder rotor are connected to one another in a torque-proof 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 or such that rotation of the lock cylinder rotor with respect to the second direction of rotation results in 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 non-rotatably connected to the lock cylinder rotor via these rotor extension elements, with the rotor extension elements also being non-rotatably connected to the lock cylinder rotor coupler and the lock cylinder rotor are connected.

It is further 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 relative to the first direction of rotation and/or such that rotation of the rotary knob rotor relative to the second direction of rotation results in rotation of the rotary knob rotor coupler relative 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 non-rotatably connected 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 as well as the rotary knob rotor.

It is further preferred that the lock bit coupler and the lock bit can be coupled to one another in such a way that a rotation of the lock bit coupler with respect to the first direction of rotation results in a rotation of the lock bit with respect to the first direction of rotation and/or such that a rotation of the lock 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.

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

The clutch device is preferably further designed in such a way 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 enabled both in the engaged state and in the disengaged state of the clutch device. The coupling device is preferably further designed in such a way that rotation of the lock bit coupler and thus of the lock bit is enabled in the event of rotation of the rotary knob rotor coupler with respect to the first direction of rotation and the second direction of rotation both in the coupled state and in the uncoupled state of the coupling device .

The rotary knob rotor coupler and/or the lock cylinder rotor coupler and/or the lock bit coupler are preferably immovable with respect to the longitudinal axis and/or immovable 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 clutch device from the engaged state to the disengaged state and/or from the disengaged state to the engaged state. In addition or as an alternative to this, 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. In the engaged state of the clutch device, a radial distance between the engagement element and the longitudinal axis is preferably smaller than a radial distance in the disengaged state of the clutch device. In other words, the engagement element preferably moves radially outwards when the clutch device transitions 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 clutch device transitions from the disengaged state to the engaged state .

As an alternative to this, however, it is just as 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 offset from one another with respect to the longitudinal axis. Additionally or alternatively, an arrangement of two or more engagement elements has a rotational symmetry with respect to a rotation about an axis of rotation D of 1.

A rotational symmetry of 1 means that the engagement element or elements can only be converted into itself with a rotation of 360°. The axis of rotation preferably corresponds to the above-mentioned axis of rotation, ie the axis of rotation running parallel to the longitudinal axis of the coupling device. In other words, 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. In the engaged state, the engagement element is preferably at least partially accommodated in this recess. In addition or as an alternative to this, the engagement element is preferably removed from this recess in the uncoupled state.

In the engaged state, the engagement element is preferably in engagement with the lock bit coupler. Additionally or alternatively, the engagement element is in disengaged state is preferably engaged with the lock bit coupler. In addition or as an alternative to this, the locking bit coupler preferably has at least one recess, the engagement element being accommodated at least partially in this recess in the engaged state and/or in the disengaged state.

The engagement member is preferably disengaged from the rotary knob rotor coupler when engaged. In addition or as an alternative to this, the engagement element is preferably engaged with the rotary knob rotor coupler in the disengaged state. In addition or as an alternative to this, 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 member is preferably configured for radial displacement. It is further preferred that the lock cylinder rotor coupler is at least partially mounted in the lock bit coupler and the lock 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 the engagement element, when the clutch 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, out of the recess in the lock cylinder rotor coupler and is increasingly shifted radially outwards in the lock bit coupler into the recess in the rotary knob rotor coupler. In the disengaged state of the coupling device, 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 turning knob rotor coupler. These components are also preferably designed and arranged in such a way that the engagement element during the transition from the disengaged state to the engaged state from the recess in the rotary knob rotor coupler and in the lock bit coupler increasingly radially inwards into the recess in the lock cylinder rotor 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 is particularly preferably in the form of a sphere. Other shapes, such as a cylindrical shape, are of course also 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 engagement elements. It is also 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 to one another with respect to the longitudinal axis and/or that an arrangement of these two or more recesses has rotational symmetry with regard 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 lock cylinder rotor coupler or the lock bit coupler preferably also have a non-symmetrical arrangement.

A number of the recesses in the knob-rotor coupler preferably corresponds to at least a number of the engagement elements. Preferably, the number of recesses in the knob-rotor coupler is twice or more than the number of engagement elements. If, for example, there are three engagement elements, 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, then the coupling device is designed for decoupling in one direction of rotation, ie in this case with respect 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 for disengaging in both directions of rotation, ie in this case with respect to the first direction of rotation and the second direction of rotation.

The lock cylinder rotor coupler and/or the rotary knob rotor coupler and/or the lock bit coupler preferably comprises at least one execution element, so that the engagement element can be at least partially disengaged 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 engaged 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 extension elements. The execution element or elements and/or the introductory element or elements are preferably around the surfaces delimiting the recess of the lock cylinder rotor coupler or the rotary knob rotor coupler or the lock bit coupler or at least regions thereof.

It is preferred that the disengagement of the engagement element from the lock cylinder rotor coupler, guided along the execution element of the lock cylinder rotor coupler, when the rotary knob rotor coupler rotates more than 0° with respect to the first direction of rotation, in particular at a rotation in a range of about 1° to 60°, particularly preferably a rotation in a range of about 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 more than 350° with respect to the first direction of rotation, in particular when it rotates in one Range from about 350° to 380°, particularly preferably in a range from about 374° to 378°. These rotations relate to an untwisted state of the rotary knob-rotor coupler. The untwisted state of the rotary knob rotor coupler can also be referred to as the basic position of the coupling device. In other words, a state in which the rotary knob device has not been actuated by a user. A twisted state of the rotary knob rotor coupler thus corresponds to a state in which the rotary knob device has been actuated by a user, preferably by turning a rotary knob of the rotary knob device with respect to the first rotational direction.

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 lock bit coupler. When the rotary knob-rotor coupler is rotated with respect to the first direction of rotation, the lock bit coupler is therefore also rotated, with the disengagement of the engagement element, which is guided along the execution element of the lock cylinder rotor coupler, from the lock cylinder rotor coupler when the Lock bit coupler with respect to the first direction of rotation of more than 0°, in particular with a rotation in a range of about 1° to 30°, particularly preferably with a rotation in a range of about 1° to 25°. The guided engagement of the engagement element with the lock cylinder rotor coupler along the insertion element of the lock cylinder rotor coupler preferably takes place when the lock bit coupler rotates more than 320° with respect to the first direction of rotation, in particular when it rotates in a range of about 320° to 360°, particularly preferably in a range of about 330° to 360°. These rotations are related here to a twisting of the lock bit coupler compared to its untwisted state.

It is further preferred that the guided engagement of the engagement element with the rotary knob rotor coupler along the insertion element of the rotary knob rotor coupler occurs when the rotary knob rotor coupler rotates more than 0° with respect to the first direction of rotation, in particular at a rotation in a range of about 5° to 60°, particularly preferably a rotation in a range of about 10° to 55°. The disengagement of the engagement element from 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 is rotated 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 from about 374° to 378°.

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

The disengagement of the engagement element from the lock cylinder rotor coupler is preferably guided along the guide element of the lock bit coupler. Particularly preferably, the engagement element is also brought into engagement with the rotary knob rotor coupler, guided along the insertion element of the lock bit coupler. This lead-out element and lead-in 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 lock bit coupler. It is further 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 from the rotary knob rotor coupler is preferably guided along the execution element of the lock bit coupler. This element is preferably in turn one and the same element. This element can therefore be referred to as a second on-off guide element. The first on-off guide member and the second on-off guide member are preferably different members from each other.

The lock 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 lock bit coupler also is rotated with respect to the first direction of rotation.

The stop element of the cam coupler is preferably an element protruding radially from an outer surface of the cam coupler, in particular from the body of the cam coupler. The stop member of the knob-rotor coupler is preferably a member protruding axially from the knob-rotor coupler. In particular, the stop member of the knob-rotor coupler extends axially, or outwardly with respect to the longitudinal axis of the coupling device, from the proximal end of the knob-rotor coupler. As mentioned earlier, the cam coupler is preferably at least partially housed within 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 a rotation of the turning knob/rotor coupler with respect to the first direction of rotation, they strike against one another and form a stop. This transfers the rotation of the rotary knob rotor coupler to the cam coupler. It is preferable that the cam coupler has two or more stopper members. Analogously, it is preferred that the rotary knob rotor coupler also has two or more stop elements.

The knob-rotor coupler preferably includes at least one locating 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. Fixing 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 locating member prevents disengagement between the engaging member and the lock cylinder rotor coupler in the absence of rotation of the 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 that faces the through-opening and is particularly preferably formed by a region of the inner surface. The fixing element is particularly preferably 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 protrudes radially inwards.

In the untwisted state of the rotary knob rotor coupler, the fixing element prevents the engaging 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, on the other hand, 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 clutch device preferably further comprises at least one restoring element, wherein the restoring element is designed to generate a restoring force on the rotary knob-rotor coupler.

The restoring force is preferably such that the rotary knob rotor coupler is converted to the untwisted state or remains in the untwisted state in the absence of a torsional force applied to the cam coupler.

This is sometimes important, because otherwise, when using the lock cylinder device with a key, the rotary knob rotor coupler would not rotate due to friction and inertia, and this would result in twisting between the rotary knob rotor coupler and the lock bit coupler, which would lead to this means that a decoupling process is started and the lock cylinder device is no longer coupled to the cam 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 lock bit coupler. Therefore, a biasing force on the return member in the home position, or in other words, the knob-rotor coupler remaining in the untwisted state in the absence of torsional force application, is also preferred. In other words, it is preferred that the restoring element exerts a restoring force on the rotary knob rotor coupler even when the rotary knob rotor coupler is not rotated. 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 mounted at least partially in the rotary knob rotor coupler and in the lock 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, e.g. magnetic elements, with the restoring force being a magnetic force.

It is further preferred that the turning knob rotor coupler and the lock bit coupler each have a pressure element against which the restoring element is preferably increasingly pressed when the turning knob rotor coupler rotates. More preferably, the pressing member of the rotary knob rotor coupler is a portion of the inner surface of the body facing the through hole of the rotary knob rotor coupler, and the pressing member of the cam coupler is preferably a portion of the inner surface of the Body facing the through hole of the cam coupler.

The cam coupler and the cam preferably each have at least one transmission element, with the transmission elements forming a stop when the cam 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 cam 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 lock bit coupler to the lock bit in both directions of rotation. The transmission element of the cam coupler is preferably an element protruding radially from the body of the cam coupler. One configuration of the transmission element of the lock bit and one configuration of the transmission element of the lock bit coupler are preferably designed to complement one another and/or for a positive connection.

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

The lock cylinder assembly preferably further includes 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 are preferably located on the inside of a building or living space, while the locking cylinder device is preferably located on the outside of a building or living space.

Furthermore, it is preferred that the lock cylinder arrangement has additional 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, in the case of an authorized key, allow the locking cylinder device to be unlocked, etc. However, mechatronic locking cylinder devices are just as conceivable, with an electrically controlled actuator for blocking the lock cylinder device would be provided.

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

Explanations in connection with the locking cylinder arrangement apply analogously to a cylinder lock comprising the locking 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 lock cylinder device comprising a lock cylinder stator and a rotor rotatably mounted in the lock cylinder Lock cylinder rotor, iii) providing a lock bit, which is rotatably mounted with respect to the rotary knob device and the lock 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 clutch device comprises a lock cylinder rotor coupler, a rotary knob rotor coupler that is mounted rotatably with respect to at least a first direction of rotation, a lock bit coupler, and at least one engagement element. The clutch 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 lock bit via the lock bit coupler. The clutch 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. In the coupled state, the engagement element engages with the lock cylinder rotor coupler. In the disengaged state, the engagement element is disengaged from 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 locking cylinder arrangement thus apply analogously to the method for producing the locking cylinder arrangement and vice versa.

DESCRIPTION OF PREFERRED EMBODIMENTS

Aspects of the inventive lock cylinder arrangement are now based on the figures discussed.

How from the Figures 1 to 8 shows, the lock cylinder arrangement 1 comprises a rotary knob device 2 comprising a rotary knob stator 29 and a rotary knob rotor 10 mounted rotatably about an axis of rotation D in the rotary knob stator 29, a lock cylinder device 3 comprising a lock cylinder stator 11 and a rotatable the axis of rotation D in the lock cylinder stator 11 mounted locking cylinder rotor 12, a lock bit 4, which is rotatably mounted about the axis of rotation D with respect to the rotary knob device 2 and the locking cylinder device 3, and a coupling device 5. The Figures 1 to 4 show a lock cylinder assembly 1 according to the Swiss profile, while the Figures 5 to 8 represent a lock cylinder arrangement 1 comprising according to the EU profile. Furthermore, the locking cylinder arrangements of these figures differ by 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, respectively. This means that the coupling device 5 according to the invention can be used both for a Swiss profile and for an EU profile.

The other components of the locking cylinder arrangements 1 shown here are commercially available and generally known components. Thus, 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 accommodating the rotary knob stator 29 or the lock cylinder stator 11, and fastening means 35, 36 such as fastening screws . The locking cylinder stator 11 and the rotary knob stator 29 are screwed to the respective housing 34 , 33 and the rotary knob 32 to the rotary knob rotor 10 by means of the fastening screws 35 , 36 .

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, reference is made to the advantage of the coupling device 5 according to the invention, which does not cause any axial forces on a key 37 accommodated in the lock cylinder device. In particular, no interactions whatsoever take place between the coupling device 5 and a key 37 that has been received. As a result, no key extensions or the like are necessary.

How good looking figure 9 shows, 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 lock cylinder arrangement. The coupling device 5 comprises a lock cylinder rotor coupler 6, a rotary knob rotor coupler 7 which is mounted rotatably with respect to a first direction of rotation d1, a lock bit coupler 8, and at least one engagement element 9. In the examples shown here, the clutch device comprises three engagement elements 9, 9a, 9b, which here each have the shape of a sphere. The rotary knob rotor coupler 7, the lock cylinder rotor coupler 6 and the lock bit coupler 8 are mounted so that they can rotate 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 components which are designed separately from one another and can be coupled to one another. It should be understood that these components can also be present in one piece, ie each in the form of a single element or piece. The locking cylinder arrangements 1 shown here also each comprise 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 and the lock cylinder stator 11 in the Housing 34 of the lock cylinder device 3 are mounted. This means that these components are also present as separate components in these examples. However, it should also be understood here that a one-piece design is just as conceivable. The clutch device 5 shown here also includes 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 clutch device 5 . In connection with the figures 9 , 19 and 22c to 30c further explanations for 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 lock bit 4 via the lock bit coupler 8 . The lock cylinder rotor coupler 6, the rotary knob rotor coupler 7 and the lock bit coupler 8 are designed in such a way that when the coupling device 5 is engaged, a power transmission from the lock cylinder rotor coupler 6 to the lock bit coupler 8 is made possible. This transmission is made possible by the engagement elements 9, 9a, 9b, which connect the lock cylinder rotor coupler 6 to the lock bit coupler 8 in a rotationally fixed manner when the coupling device 5 is in the engaged state. This connection is released by transferring the coupling device 5 from its engaged state to its disengaged state by twisting the rotary knob rotor coupler 7 relative to the lock bit coupler 8, which causes the rotary knob rotor coupler 7 and the lock bit Coupler 8 against the lock cylinder rotor coupler 6 is made possible.

How from the figures 9 and 10 shows, the locking cylinder rotor coupler 6 comprises a substantially cylindrical body 39 with a proximal end 40 and a distal end 41. In the region of the proximal end 39, a coupling structure 42 is provided which is a coupling with the locking cylinder rotor 12 or with a rotor extension element 30, so that a rotation of the lock cylinder rotor 12 or of the rotor extension element 30 can be transmitted to the lock cylinder rotor coupler 6. In particular, this coupling structure 42 is designed for a non-rotatable connection with 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 from the distal end 41 of the body 39 along the longitudinal axis L away. This locking structure 43 also has an essentially cylindrical shape here. A cross section of the locking structure is smaller than a cross section of the body 39. The locking cylinder rotor coupler 6, in particular its body 39, here comprises three recesses 13, 13a, 13b. The recesses 13, 13a, 13b are designed to complement the engagement elements 9, 9a, 9b and have the shape of circular openings. In the engaged state of the coupling device 5, the engagement elements 9, 9a, 9b are at least partially accommodated in these recesses 13, 13a, 13b. In the disengaged state of the coupling device 5, the engagement elements 9, 9a, 9b are removed from these recesses 13, 13a, 13b.

In the Figures 11 to 14 1 shows the cam coupler 8, which here also comprises a substantially cylindrical body 44 with a proximal end 45 and a distal end 46. Next he has a through hole 47, which extends from proximal end 45 to distal end 46 along longitudinal axis L through body 44 . Analogously to the lock cylinder rotor coupler 6, the lock bit coupler 8 also has recesses 14, 14a, 14b, which are designed to complement the engagement elements 9, 9a, 9b and have the shape of circular openings here. 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.

As in the Figures 15 and 16 As can be seen, the turning knob rotor coupler 7 also comprises 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 coupling to the rotary knob rotor 10 or to 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 turning knob rotor coupler 7 . In particular, this coupling structure 52 is designed for a non-rotatable connection with the rotary knob rotor 10 or a rotor extension element 31. Analogous to the lock bit coupler 8 and the lock 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 when the clutch device 5 is in the disengaged state and are removed from these recesses 15, 15a, 15b in the engaged state of the clutch 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 lock cylinder rotor coupler 6 protrudes distally from the lock bit coupler 8 . In addition, the lock 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, with the locking structure 43 of the lock cylinder rotor coupler 6 also being at least partially through the through-opening 51 of the rotary knob Rotor coupler 7 and protrudes distally from the body 48 of the rotary knob rotor coupler 7 .

As in particular in the figures 9 and 20 As can be seen, the coupling device 5 further includes 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 here 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 immovably 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 cam coupler 8. In a third step, the spacer 38 is placed 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 including the reset element 27 is connected to the lock bit coupler 8 and the lock cylinder rotor coupler 6 accommodated therein. In a sixth step, the securing 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 offset relative to 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 axis of rotation D of FIG. 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 offset from one another with respect to the longitudinal axis L and also have rotational symmetry with respect to a rotation about the axis of rotation D of FIG. This asymmetrical design means that engagement is only possible at certain rotational positions of the rotary knob rotor coupler 7 .

In the examples shown, the engaging elements are 9, 9a, 9b with respect to the longitudinal axis L is immovably but radially displaceable with respect to the radial axis R and perform a radial displacement along the radial axis R during a transition of the clutch device 5 from the engaged state to the disengaged state and from the disengaged state to the engaged state. This radial displacement is in particular by comparing the Figures 22a to 29c clearly which different coupling states of the coupling device 5 represents. 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 shows, the clutch 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 for example in the Figures 20 and 22a to 22c is shown, the engaging elements 9, 9a, 9b are engaged with the lock cylinder rotor coupler 6. In the decoupled state of the coupling device 5, as 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 can be rotated relative to the lock cylinder rotor coupler 6 in the disengaged state. As can also be seen from these figures, a radial distance between the engagement elements 9, 9a, 9b and the longitudinal axis L when the coupling device 5 is engaged is smaller than a radial distance when the coupling device 5 is disengaged Figures 22a , 23a and 24a shows that the engagement elements 9, 9a, 9b are released from the recesses 13, 13a, 13b in the lock cylinder when the clutch 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 shifted radially outwards into the recesses 15, 15a, 15b in the rotary knob rotor coupler 7. In the disengaged state of the coupling device 5, the engagement elements 9, 9a, 9b are completely removed from the recesses 13, 13a, 13b of the lock cylinder rotor coupler 6 and are located in the recesses 14, 14a, 14b of the lock bit coupler 8 and the recesses 15, 15a, 15b of the rotary knob rotor coupler 7, see eg Figures 24a, 25a and 26a . When the coupling device 5 is transferred back into the engaged state, the engagement elements 9, 9a, 9b are released 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 moved back into the recesses 13, 13a, 13b in the lock cylinder rotor coupler 6 radially inwards, see eg Figures 27a, 28a and 29a .

The lock cylinder rotor coupler 6, the rotary knob rotor coupler 7, and the lock bit coupler 8 comprise execution elements 16, 17, 18, along which the engagement elements 9 are guided, at least partially, disengaged. Also, the lock cylinder rotor coupler 6, the turning knob rotor coupler 7 and the lock bit coupler 8 each comprise insertion elements 19, 20, 21, along which the engaging elements 9 are guided at least partially engaged. These lead-out elements 16, 17, 18 and lead-in elements 19, 20, 21 are in each case the recesses 13-13b, 14-14b, 15-15b of the lock cylinder rotor coupler 6 or the turning knob rotor coupler 7 or the lock 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 turning 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 relate to an untwisted state of the rotary knob rotor coupler 7, as for example in the 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 in a single rotation of the rotary knob rotor coupler 7 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, 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 range from about 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 one area when the turning 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 from the lock cylinder rotor coupler 6 along the extension elements 17 of the lock bit coupler 8 and the engagement of the engagement elements 9, 9a, 9b guided along the introduction elements 20 of the lock bit coupler 8 with the rotary knob rotor coupler 7 are here along the same surfaces. These surfaces are therefore also referred to herein as the first on/off guide elements 22 of the lock bit coupler 8 . The engaging 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 engaging elements 9, 9a, 9b are disengaged from the rotary knob rotor coupler 7 in a similar manner along the execution elements 17 of the lock bit coupler 8 along the same surfaces. These surfaces are therefore also referred to herein as second on-off guide elements 23 .

How from the figures 9 , 19 and 22c to 30c shows, the clutch 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 converts to the untwisted state in the absence of a rotational force acting on the rotary knob rotor coupler 7 relative to the cam coupler 8 becomes or remains in the untwisted state. The restoring element 27 is mounted in the rotary knob rotor coupler 7 and in the lock bit coupler 8 . As for example in figure 9 As can be seen, the body 48 of the rotary knob rotor coupler 7 comprises 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 pushed 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 assembled state of the coupling device 5 in the distal Area of the cam coupler 8 stored. This distal area of the lock bit coupler 8 has the shape of a semicircular receptacle 55 here. Furthermore, the turning knob rotor coupler 7 and the lock bit coupler 8 each have a pressure element 56, 57 against which the restoring element 27 is increasingly pressed when the turning knob rotor coupler 7 rotates. The pressing member 56 of the knob-rotor coupler 7 is a portion of the inner surface of the body 48 which faces the through hole 51 of the knob-rotor coupler 7 . The pressure element 57 of the lock bit coupler 8 is also an area of the inner surface of the body 44 which faces the through opening 47 of the lock bit coupler 8 . This is particularly the case figures 22c , 23c , etc.

As in particular from the Figures 22a and 22b shows, 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 coupled 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. Specifically, the fixing elements 26 are each formed here 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 cannot protrude from the recesses 13, 13a, 13b of the lock cylinder rotor coupler 6 can move out. If the rotary knob rotor coupler 7 is rotated, however, its fixing elements 26 are also rotated accordingly and are thereby moved away from the engagement elements 9, 9a, 9b, whereupon the engagement elements 9, 9a, 9b move out of the recesses 13, 13a, 13b in the lock cylinder -Rotor coupler 6 can move out, see eg Figures 23a, 23b, 24a and 24b .

This means that the engagement elements 9, 9a, 9b can be disengaged from the locking cylinder rotor coupler 6 by rotating the rotary knob rotor coupler 7 with respect to the first direction of rotation d1. Then there is the coupling device 5 in the disengaged state, as for example in the Figures 24a to 26c is shown. As can further 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, the recesses 14, 14a, 14b of the lock bit coupler 8, and the recesses 15, 15a, 15b of the turning knob rotor coupler 7 a re-engagement as long as the rotational position of the turning knob rotor coupler 7 is not correct. In other words, the recesses 13-13b, 14-14b, 15-15b for the engagement elements 9, 9a, 9b are only accessible when the rotary knob rotor coupler 7 is in a specific rotary position. Otherwise, the engagement elements 9, 9a, 9b abut against the body 39 of the lock cylinder rotor coupler 6, see eg Figures 24a, 24b, 25a, 25b, 26a and 26b .

the Figures 27a to 28c show the coupling device 5 shortly before reaching its reconnected 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, in this case 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, is the coupling device 5 in the vicinity of its original position, as shown in FIGS Figures 27a to 27c is shown, the lock bit coupler 8 is twisted back by the spring preload as soon as there is space, which means that the engagement elements 9, 9a, 9b are pushed back into the lock cylinder rotor coupler 6 again. This state is in the Figures 28a to 28c shown. In this state, however, the clutch device 5 is not yet fully engaged. To do this, the user must release the knob-rotor coupler 7, with the remaining spring preload returning the knob-rotor coupler 7 to the original position, ie to the basic position, with respect to the second direction of rotation d2. Only then is the coupling device 5 fully engaged again, see FIG Figures 29a to 29c .

As just mentioned, the coupling device is 5 of Figures 29a to 29c in a basic state, i.e. a non-twisted state of the rotary knob rotor coupler 7 but also of the lock cylinder rotor coupler 6. If an authorized key 37 is now received in the lock cylinder device 3, the non-rotatable connection of the lock cylinder rotor coupler 6 with the other components of the coupling device 5 to the fact 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, the components of the coupling device 5 do not move relative to one another when the lock cylinder rotor coupler 6 is rotated by turning an authorized key 37, see FIG Figures 30a to 30c .

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

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

Twisting of the lock bit coupler 8 in the event of a twist of the rotary knob 32 is caused by stop elements 25 of the rotary knob rotor coupler 7, which form a stop with corresponding stop elements 24 of the lock bit coupler 8, see figures 9 and 31 . The stop elements 24 of the lock bit coupler 8 are each elements that protrude radially from the outer surface of the lock bit coupler 8 . The stop elements 25 of the rotary knob rotor coupler 7 are elements that protrude axially from the rotary knob rotor coupler 7 and 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 twisting of the lock bit 4 is caused by the twisting of the lock bit coupler 8 . For this purpose, the cam coupler 8 has a transmission element 28 which interacts with a corresponding transmission element of the cam 4 . How from the figures 9 , 32 , 33 , 35 and 26 shows that the transmission element 28 of the lock bit coupler 8 is an element that protrudes radially from the body 44 of the lock bit coupler 8 .

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