Description

The present invention relates to a clutch assembly for a lock cylinder, comprising a housing, a switching element disposed in the housing, a drive means disposed in the housing, and a coupling device displaceable between a coupling position and a disengaging position.

Such coupling arrangements are in the prior art, for example from the document EP 2 302 149 A1 known.

Such clutch assemblies are used, in particular in electromechanical lock cylinders, to switch between a clutched state and a disengaged state. In the dome state is an actuator, For example, a handle or a door knob rotatably connected by means of the clutch assemblies with a cam for actuating a lock of the corresponding door. In the uncoupled state, the actuator is freely rotatable, so that the lock can not be operated.

Between the dome state and the decoupled state is switched back and forth in response to a received authorization signal. The input of such an authorization signal can be wireless or via a corresponding control by a person. An evaluation then checks whether an authorization to open the door is present and optionally switches the clutch assembly in the coupled state.

In addition, coupling arrangements are also known which lock or release a shaft of the actuating element against the door to be opened or another stationary object in a rotationally fixed manner. With a confirmed authorization to open the door, the shaft of the actuator is then unlocked so that the actuator can be rotated and a lock can be operated. Otherwise, the actuator can not be rotated due to the obstruction against the door or the other object.

All these embodiments have in common that an electromechanical clutch assembly is required, which can switch between two switching states, a coupled state and a decoupled state, back and forth. Usually, an electric motor is activated. The movement of the electric motor is then translated into a movement of mechanical elements for coupling and decoupling.

In particular, in the said case that by means of the clutch assembly in a coupled state, an actuating member is rotatably coupled and can rotate freely in a decoupled state, the case may arise that due to the position of the actuating element, in particular a freely rotatable door knob, the clutch assembly does not the uncoupled state can be put into the coupled state. In general, this is because the intended coupling elements instead of interfering with each other due to their position relative to each other. Only by a continued rotation, for example, the doorknob then get these elements back into a position relative to each other, in which they can interlock. During such a period, however, it is undesirable to permanently energize the corresponding drive device and to apply a force to the mechanism so that the coupling elements move into one another when the relative position is appropriate. This is partly due to the fact that the mechanical elements involved should be as low as possible and durable in the long term, on the other hand, that thereby the energy consumption increases significantly. Therefore, it is endeavored to have to apply the force required for a single switching operation or the required moment only once by means of the drive means. Furthermore, so-called force accumulators are provided which, in the case of the collision or blocking of elements involved in the coupling process, store and then release the force or energy when the relative position of the elements involved changes.

In the prior art, various solutions have been proposed for such power storage. On the one hand there are mechanical solutions that often use spring elements as energy storage. In addition, there are also solutions that make use of magnetic fields.

Furthermore, it is endeavored in the prior art to be able to cover as large a variety of door geometries and fields of application with certain concepts for clutch arrangements or elements of lock cylinders. Also, it increasingly happens that lock cylinder systems must be changed, so that a variety of uses in retrofitting and repair area is required.

Therefore, in the prior art, in addition to lock cylinder systems that are designed specifically for a specific installation situation, also modular arrangements known about adapter pieces or shaft extensions in a variety of installation situations, such as one or two-sided operable doors, doors of different thickness, etc., can be used are.

This is how the document shows EP 1 736 622 A1 a lock cylinder with a lock cylinder housing, in which on one or both sides a rotatable by a knob knob shaft is rotatably supported, and with electrical and / or electronic and / or magnetic and / or electromagnetic and / or electromechanical and / or mechanical functional elements, to which at least one Closing element and at least one electromechanically operating coupling means which rotatably connects the closing element with the knob shaft due to an authorization signal and / or releases the knob shaft to actuate a lock, as well as include a transmitter that generates the authorization signal due to an input or an input signal. The knob shaft consists of at least two segments which are rotatably connected to each other, wherein at least one functional element is arranged in at least one segment.

In the area of operating by means of magnet coupling arrangements, the document mentioned above shows EP 2 302 149 A1 an actuating device, for example in the form of a lock cylinder or a lever handle with a drive member mounted in a housing and a movable by actuation of the drive member in an operative position of a switching member output member, wherein the switching member by magnetic force during displacement of a switching element associated first magnet between the active position and a Counteracting position is movable back and forth, in which counteracting position a movement of the driven part is prevented by pressing the drive member. The manipulation security of such an actuator is to be increased by a second magnet adjacent to the first magnet and oppositely poled to the first magnet and associated with the switching member, wherein the two identically designed magnets build up a substantially vanishing quadrupole moment in the distance.

A similar arrangement shows the document DE 10 2008 018 297 A1 , This document shows a lock cylinder with a housing, a rotatably mounted in the housing closure member and at least one drive shaft which is switchable by means of a movable magnetic actuator by a magnetic actuator slide between a rotatable uncoupled position and a rotationally fixed coupling position to the closing member. To the switching mechanism between To improve coupling position and uncoupled position, one or more coupling members, which are acted upon by the force of a spring einliegen in coupling recesses from which they can dodge in the uncoupled position, and by being slidably held in the coupling position, are provided.

Furthermore, the document shows DE 10 2009 043 358 A1 a lock cylinder with a housing, a rotatably mounted in the housing closing member and at least one drive shaft which is switchable by means of a first magnet by magnetic force displaceable closing member between a rotatable uncoupled position and a rotationally fixed coupling position to the closing member.

Furthermore, the document shows EP 1 443 162 A2 a lock cylinder, in particular profile cylinder, with a shaft, a component disposed substantially concentrically with the shaft and a coupling arrangement for coupling the shaft to the component, wherein the coupling arrangement comprises at least one coupling element, which between a coupling position in which the coupling element, the shaft and the Component in the rotational direction positively connects to each other, and a Entkuppelposition is displaceable, in which the shaft and the component are uncoupled in the rotational direction of each other, and having a drive which is adapted to move a drive member, thereby to displace the coupling element. In this case, at least one permanent magnet is arranged on the drive member and / or on the coupling element, which is designed to move the coupling element during a movement of the drive member.

Based on this prior art, it is an object of the present invention to provide an improved clutch assembly that is inexpensive to manufacture, durable and tamper-resistant, and is suitable for use in as many types of applications and installation situations as possible.

According to the invention, it is therefore proposed to further develop the coupling arrangement mentioned at the outset such that the switching element is rotatable about a switching axis by means of the drive device, wherein the switching element is fixed in the axial direction with respect to the switching axis, and wherein the coupling device rotatably and parallel to the shift axis displaceable in the housing is mounted, wherein the switching element or the coupling device has at least one first designed as a permanent magnet solenoid, wherein a polar axis of the at least one shift magnet is parallel to the shift axis, and wherein the other accordingly from the coupling device and the switching element has at least a first pair of dome magnets, each dome magnet is designed as a permanent magnet, wherein the pole axes of the dome magnets of a pair of dome magnets each parallel to the shift axis, and wherein the dome magnets of a pair of dome magnets are polarized in opposite directions.

Furthermore, a lock cylinder is proposed with such a coupling arrangement or one of its embodiments with a concentrically arranged to the housing component, wherein the housing and the component in the coupling position in the rotational direction are positively connected to each other, and in the Entkuppelposition the housing and the component in the direction of rotation disconnected from each other.

• Bereitstellen der Kupplungsanordnung in einer ersten Schaltposition, in der der erste Schaltmagnet mit einem ersten Kuppelmagneten von dem ersten Paar von Kuppelmagneten derart zusammenwirkt, dass die Kuppeleinrichtung in die Entkuppelposition versetzt ist, und
• Drehen des Schaltelements um die Schaltachse in die zweite Schaltposition, so dass der erste Schaltmagnet mit einem zweiten Kuppelmagneten von dem ersten Paar von Kuppelmagneten derart zusammenwirkt, dass sich die Kuppeleinrichtung in bezüglich der Schaltachse axialer Richtung bewegt und in die Kuppelposition versetzt wird.

Furthermore, a method for coupling two elements of a lock cylinder is proposed by means of a coupling arrangement, wherein the coupling arrangement comprises a drive device for rotating a switching element about a switching axis and a coupling device which is displaceable with respect to the switching axis in the axial direction between a dome position and a Entkuppelposition the switching element or the coupling device has a first switching magnet designed as a permanent magnet, wherein a polar axis of the at least one switching magnet is parallel to the switching axis, and wherein the corresponding other of the coupling device and the switching element has at least a first pair of dome magnets, each dome magnet as a permanent magnet is formed, wherein the pole axes of the dome magnets of a pair of dome magnets are each parallel to the shift axis and are poled in opposite directions, with the following steps:

• Providing the clutch assembly in a first shift position in which the first shift solenoid cooperates with a first dome magnet of the first pair of dome magnets such that the dome is offset to the disengaged position, and
• Rotating the switching element to the switching axis to the second switching position, so that the first switching magnet with a second dome magnet of the first pair of dome magnets cooperates such that the coupling device moves in relation to the switching axis axial direction and is set in the dome position.

The clutch assembly, the lock cylinder and the method make it possible to effect the rotational movement of the drive device in a translational movement of the coupling device parallel to the shift axis in a secure manner. The drive device may in particular be a stepper motor. In addition, by means of the magnets, in particular of the at least one switching magnet and the first and the second dome magnet, an effective functionality allows, as it should be met by a force storage. At the same time a compact construction is possible, and the elements involved are not subject to any wear. Thus, a durable durability and maintenance freedom of the arrangement is given.

Furthermore, it is possible to couple with respect to the switching axis axial direction. In particular, it can thus be avoided to have to couple over a peripheral surface. This not only allows the use as a replacement element in door elements of predetermined nature and specific bore diameters, as interaction with adjacent to a peripheral surface elements is avoided, but also the use in modular lock cylinder arrangements, since the front side with respect to the switching axis axial direction then in Rotational direction positive coupling is made possible, for example by means of at least one with respect to a rotational axis of a knob shaft eccentrically arranged pin member.

The object initially posed is therefore completely solved.

In one embodiment of the clutch assembly can be provided that the switching element is rotatable in a first switching position and in a second switching position, wherein in the first switching position of the first solenoid with a first dome magnet of the first pair of dome magnets cooperates such that the coupling device is set in the uncoupling position, and wherein in the second switching position, the first switching magnet cooperates with a second coupling magnet of the first pair of coupling magnets such that the coupling device is set in the coupling position.

In this way, it is ensured that, in the first switching position, the first switching magnet cooperates with a first coupling magnet of the first pair of coupling magnets and in the second switching position the switching magnet cooperates with a second coupling magnet of the first pair of coupling magnets. In this way, the opposite polarity of the dome magnets of the pair of dome magnets can be exploited to offset the coupling device. This saves complex solutions that require a rotation of magnets around their own longitudinal or transverse axis. The mechanical structure is significantly simplified in this way, which makes the production more cost effective and the overall structure more robust.

In a further embodiment of the coupling arrangement can be provided that the switching element has the at least one first formed as a permanent magnet switching magnet, and wherein the coupling device comprises the at least one first pair of dome magnets.

This accurate assignment of the switching magnet to the switching element and the pair of dome magnets to the coupling device allows a particularly space-saving design. In particular, in this way, as will be explained in more detail below and configured, the possibility of using multiple solenoids and multiple pairs of dome magnets is simplified.

In a further embodiment of the coupling arrangement can be provided that the housing is formed as a cylindrical hollow shaft, wherein the housing extends along a longitudinal axis, wherein the switching axis is the longitudinal axis or parallel to the longitudinal axis straight line, and wherein the housing is a perpendicular to Having the longitudinal axis extending end face.

In this way, the clutch assembly may be provided as, for example, a module for use in a modular or segmented knob shaft. The installation in Knaufwellen or lock cylinder arrangements for use in fixed installation situations is particularly easy in this way possible. The coupling direction parallel to the longitudinal axis is achieved by the parallelism of the indexing axis with the longitudinal axis. In this way it is possible to design the coupling arrangement such that it is coupled over the end face. This is also advantageous in particular for use in modular lock cylinder arrangements, since a selective coupling with elements adjoining in the axial direction is made possible.

In a further embodiment it can be provided that the end face is a coupling surface of the coupling arrangement, wherein at least a portion of the coupling device protrudes eccentrically in the dome position with respect to the longitudinal axis of the end face and is withdrawn in the uncoupling position in the housing.

In this way, it is thus provided that, via the coupling arrangement, which protrudes from the end face in the coupling position, a positive-locking coupling with an element adjoining in the axial direction can be brought about in the direction of rotation. In the decoupled position, this portion of the clutch assembly is retracted into the housing so that there is no clutch with the adjacent member and as far as the clutch assembly or its housing can be freely rotatable.

In a further embodiment of the coupling arrangement can be provided that the coupling device comprises at least a first pin member and a disc member in which the at least one first pair of dome magnets is received, and wherein the at least one first pin member on the disc element with respect to the switching axis in the axial direction and rotationally fixed, and wherein the at least one first pin member extends from the disc member in the axial direction.

In this way, it is possible to hold by means of the disc element as a kind of support element at least a first pin element and also in the case of more than one pin element to move all pin elements together.

In a further embodiment of the clutch assembly can be provided that the drive means comprises a coaxial to the shift axis extending drive shaft, wherein the switching element by means of a sleeve portion rotatably connected to the drive shaft, and wherein the switching element is a from the sleeve portion in respect to the shift axis radial direction extending first wing carrier, which carries the first switching magnet.

In this way, an axially compact design is achieved, in which the switching element can be directly connected rotationally fixed to a drive shaft of the drive device. Radially outwardly there extends a first wing carrier, which then carries the first switching magnet and can be rotated by actuation of the drive device.

In a further embodiment it can be provided that the disc element of the coupling device is mounted on the sleeve portion of the switching element.

In this way, an even more compact design is also possible. The first switching magnet on the first wing carrier can thus be rotated relative to the coupling device and optionally interact with the first or second coupling magnet of the pair of coupling magnets. The disc element is then displaced in the axial direction on the sleeve portion of the switching element when the switching position is changed.

In a further embodiment of the coupling arrangement can be provided that the coupling arrangement comprises two pairs of dome magnets.

The use of a second pair of dome magnets can in particular provide a uniform application of force to the disc element, which can avoid tilting of the disc element on the sleeve section.

In a further embodiment of the coupling arrangement can be provided that the switching element comprises a second wing carrier, in which a second switching magnet is received, wherein the second wing carrier with respect to the switching axis opposite to the first wing carrier extends in the radial direction, and wherein a polarity of the second Solenoid corresponding to the first switching magnet in the axial direction.

In this way, both pairs of dome magnets can be applied simultaneously and used to move the clutch assembly. As a result, the total shift forces increase, and these are also introduced symmetrically with respect to the shift axis in the coupling device.

In a further embodiment of the coupling arrangement can be provided that the switching element has a third wing carrier, in which a third switching magnet is received, wherein the third wing carrier with respect to the switching axis axially spaced from the first wing carrier extends in the radial direction, wherein a pole axis of the third Switching magnet coaxially with the switching axis of the first switching magnet, and wherein the polarities of the first switching magnet and the third switching magnet are in the opposite direction in the axial direction.

In this way, the acting magnetic forces can be increased again. Due to the opposite orientation of the polarities of the first switching magnet and the third switching magnet, one of these switching magnets acts attractively together with the dome magnets of the first pair of dome magnets and the other one together in a repulsive manner. In this way, the switching forces can be significantly increased.

In a further embodiment, it may be provided that the switching element has a fourth wing carrier, in which a fourth shift magnet is received, wherein the fourth wing carrier extends with respect to the shift axis opposite to the third wing carrier in the radial direction, and wherein a polarity of the fourth shift magnet in axial direction of the third switching magnet corresponds, wherein a pole axis of the fourth switching magnet coaxial with the pole axis of the second switching magnet, and wherein the polarities of the fourth switching magnet and the second switching magnet in the axial direction are in opposite directions.

In this way, an increased and symmetrical application of force to the coupling device is made possible, since even the second pair of dome magnets on one side attracting and on the other side is repulsively subjected to field forces. In addition, the disc member is securely held on the sleeve portion between the first and third wing carrier and the second and fourth wing carrier.

In one embodiment of the coupling arrangement can be provided that the disc element between the first and third wing carrier or the second and fourth wing carrier with respect to the switching axis is arranged axially displaceable on the sleeve portion.

In this way, the disk element can not fall off the sleeve portion. The travel paths of the disc element are limited by the wing carrier.

In a further embodiment of the coupling arrangement can be provided that the coupling device comprises two pin elements, which are arranged opposite to each other with respect to the switching axis.

In particular, it can be provided that the two pin elements are arranged diametrically opposite to each other with respect to the switching axis. In this way, by means of the pin elements or a respective pin element with respect to the shift axis radially inwardly supporting housing portion simultaneously in the direction of rotation one stop is provided for each of the wing carriers. This avoids that a wing carrier in the direction of rotation during rotation between the first and the second switching position is rotated too far. Fixed attacks are provided which would also allow realignment in the event of a step loss.

In a further embodiment of the coupling arrangement can be provided that the pole axes of a respective switching magnet and the first coupling magnet of a respective pair of coupling magnets in the first switching position and the pole axes of the respective switching magnet and the second coupling magnet of a respective pair of coupling magnets in the second switching position spaced from each other are.

In the switching positions, therefore, the pole axes do not necessarily have to be coaxial with one another. These may also be offset from each other, yet the magnetic field forces may be sufficient to allow displacement of the coupling device.

In particular, it can be provided that a pole axis of a switching magnet is arranged in both the first and the second switching position in the circumferential direction between a polar axis of a dome magnet and a pin member.

In this way, it is not necessary to apply any form of holding forces in the first switching position or the second switching position, so that the coupling arrangement holds its respective position. The wing carriers are then trapped by the magnetic field forces and the bearing provided in the direction of rotation on the pin elements in the respective switching position and can not get into another position without re-actuation of the drive device. Thus, an energization of the clutch assembly is necessary only for a switching operation. Holding forces applied by the drive device are necessary neither in the first nor in the second switching position.

In a further embodiment it can be provided that the housing is divided into two parts in the longitudinal direction.

In this way, a particularly simple assembly of the entire coupling arrangement in the housing is made possible.

In one embodiment of the lock cylinder can be provided that the component is a cam or a shaft segment of a segmented knob shaft.

Thus, a coupling can be made both directly with a lock bit for actuating a lock and in any other shaft segment, such as an extension module or any other segment.

In a further embodiment of the lock cylinder can be provided that the housing is a shaft segment of a segmented knob shaft of the lock cylinder, a handle of the lock cylinder or a knob shaft of the lock cylinder. The coupling arrangement can thus directly form a shaft segment or module of a segmented or modular knob shaft. Furthermore, the coupling arrangement can be arranged in a handle, for example a doorknob, a door handle or another actuating device, or the housing can be the knob shaft of the lock cylinder, so that the knob shaft can be coupled with a component, for example the cam, at the front.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Fig. 1 shows a schematic view of the arrangement of a lock cylinder 10 in a door 12. The lock cylinder is used, in the presence of a person, to allow the actuation of a lock 14 to open the door 12. The door 12 in this case has an outer side 18, is assumed in the present example that people want to gain access from here. Opposite the outer side 18 is an inner side 20, which constitutes a safe area in the present example.

Accordingly, on an outer side of the door 12, for example, a handle, such as an outer knob 22, arranged. In the present example, this outer knob 22 has a receiving device 24 and / or an input device 26, via which an authorization signal, for example from an RFID chip or an active wireless signal, can be received or via which, for example, a code can be typed. It is then evaluated whether the transmitted or entered code authorizes opening of the door 12 and, if so, opening of the door 12 is enabled.

In order to optionally provide for opening the door 12, it is provided that the outer knob 22 couple in the direction of rotation via a knob shaft 32 in a coupling position with the closing element 16 and not in a uncoupling position. A provided between the outer knob 22 and the closing element 16 outer knob shaft is designated by the reference numeral 32. The knob shaft 32 extends within a lock cylinder housing 30 and rotates relative to the lock cylinder housing 30. On an inner side of the door 12 can also be a handle, such as an inner knob 28, may be provided, which in turn is coupled to an inner knob shaft 34 with the closing element 16. In the example shown, the inside 20 is safe. The inner knob 28 is therefore permanently coupled via the inner knob shaft 34 with the closing element 16. It is therefore always possible to actuate the closing element 16 by means of the inner knob. In contrast, however, a coupling arrangement 40 is provided between the outer knob 22 and the closing element 16. This is the outer knob 22 only rotatably coupled with the closing element 16, if an authorization exists. For the clutch assembly 40 thus there are two states. First, a Entkuppelposition in which the outer knob 22 is freely rotatable about an axis of rotation 38 of the knob shaft 32, and a dome position in which the outer knob 22 is rotatably coupled to the closing element 16.

For the arrangement of coupling arrangement 40 there are several possible positions, which are designated 40, 40 'and 40 "For example, the coupling arrangement can be arranged directly in the outer knob 22 and couple it with the knob shaft 32 or decouple. a coupling arrangement is designated, which is arranged within the knob shaft 32. Here, the coupling arrangement provides 40 quasi for bringing two partial waves of the clutch shaft 32 with each other or not. Furthermore, the coupling arrangement, as indicated at 40 ", can of course be arranged directly at one end of the coupling shaft 32 and optionally engage directly in the closure element 16 in a rotationally secure manner or be decoupled from it "possible positions for coupling surfaces.

An axial direction with respect to the axis of rotation 38 is in the Fig. 1 schematically denoted by X. The corresponding radial plane then results from the spatial directions Y and Z.

The coupling surfaces thus extend in the illustrated example thus perpendicular to a rotation axis 38 of the knob shaft. In the prior art, couplings over a circumferential surface are also known in principle. Furthermore, it is also known, instead of a rotationally fixed coupling or decoupling of elements by means of a coupling arrangement optionally a block shaft 32 against a lock cylinder housing 30 to block or release. These obstructions also take place via a corresponding lateral surface. A knob shaft 32 thus generally has the shape of a cylinder. This knob shaft is rotatably mounted in a lock cylinder housing. In principle, it is also possible to store a knob shaft directly, that is to say without lock cylinder housing 30, in a door 12. However, the clutch assemblies contemplated herein are particularly suitable for use in coupling to end surfaces of the respective elements. Here, the peculiarity is that the respective coupling surfaces 36, 36 'and 36 "are aligned perpendicular to a rotation axis 38. A significant advantage provided thereby is the compatibility with any doors 12, since structural measures in a radial plane within the Door 12 are not necessary.

Of course, it is quite possible in the embodiments that also the inner knob 28 is coupled to the closing element 16 by means of a coupling arrangement 40 in the manner described above. In this case, then both the inside and the outside actuating the door 12 is linked to a permission.

The Fig. 2 shows a further possible use of a clutch assembly 40 in the context of a modular lock cylinder 10 '. Identical elements are identified by the same reference numerals and will not be explained again below.

Once again, by means of an outer knob 22 in a dome position, a closing element 16 for actuating the lock 14 is to be coupled. For this purpose, a multi-module knob shaft 32 is provided. For example, a module of the knob shaft 32 may be the clutch assembly 40. Another module 46 may carry the closure member 16. Another module 44 may be formed as an extension module depending on the thickness of the door 12 to couple the modules 40 and 46 rotatably. The clutch assembly selectively couples via the clutch surface 36 to the adjacent module 44. The clutch assembly 40 may then be mounted in or on the outside knob 22, for example. In principle, the modules 40, 44 and 46 of the knob shaft 32 can be arranged directly in the door 12. You can also choose, similar to the representation in the Fig. 1 be surrounded by a lock cylinder housing 30.

Similarly, another internal knob shaft 34 is formed of two modules. A module 48 couples with the inner knob 28 and may for example have a standard length. Furthermore, an extension module 42 is used to adapt to a thickness of the door 12. Of course, similar, as in the Fig. 1 explained, the inner knob shaft 34 may be provided with an electromechanical coupling of order 40, even if an authorization 20 is to be queried on an inner side.

An embodiment of the coupling arrangement 40 will be described below in connection with FIGS Fig. 3 to 7 explained. At first it is in the Fig. 3 explained in detail the embodiment of a switching element 50 and subsequently in connection with the Fig. 4 the embodiment of a coupling device 80 explained. The Fig. 5 and 6 then go into the whole setup in both the uncoupling position and the dome position. In connection with the Fig. 7 Geometrical details of dimensioning are explained.

Fig. 3 shows an embodiment of a switching element 50. The switching element 50 is rotatably mounted in the clutch assembly about a shift axis 52. In the following, the terms "in the axial direction" are therefore to be understood with reference to the switching axis 52, they thus refer to a direction parallel to the direction X. Consequently, "in the radial direction" refers to a direction perpendicular to the switching axis 52, that is to say in FIG YZ plane. A "rotation direction" 136 thus denotes a rotation of the switching element 50 about the switching axis 52.

The switching element 50 has an inner recess 54. This may have a cross-sectional profile, so that a rotationally fixed coupling with a drive device (in Fig. 3 not shown) in a rotationally stable manner can be produced. For example, the recess 54 may have a non-rotationally symmetrical cross-section which corresponds to that of a drive shaft of the drive device.

Furthermore, the switching element 50 has a sleeve section 56. The sleeve portion 56 extends with kontantem cross section in the axial direction. The sleeve portion 56 is bounded at both ends in the axial direction by wing carrier 58, 59, 60, 61. In principle, at least one first wing carrier 58 is to be provided. In this case, an opposite end may be provided by a simple flange of the sleeve portion 56 which extends radially outwardly at an end of the sleeve portion 56 opposite the first wing carrier 58. The first wing carrier 58 extends in the radial direction, starting from the sleeve portion 56 to the outside and has a first switching magnet 62. The first switching magnet 62 is designed as a permanent magnet. The first shift magnet 62 has a first pole axis 66. A polarity of the polar axis is indicated by the letters "N" and "S". The polarities shown in the figures are to be understood merely as examples with regard to their absolute north-south orientation. Accordingly, the polarity of the first switching axis 66 could also be configured differently. Then arise for all other pole axes of the switching element and in the Fig. 4 shown dome devices according to also opposite polarity.

In a corresponding manner, a second wing carrier 59 is provided, which extends from the sleeve portion 56 in the direction opposite to the first wing carrier 58 radially outward direction. The second wing carrier 59 carries a second switching magnet 63. The second switching magnet 63 has a second pole axis 67. A polarity of the second pole axis 67 is identical to that of the first pole axis 66. The pole axes 66 and 67 extend parallel to the switching axis 52.

Correspondingly, on a first end and the second wing carrier 58, 59 opposite end of the sleeve portion 56, a third wing carrier 60 and in a radially opposite direction to the third wing carrier 60 extending fourth wing carrier 61. The third wing carrier 60 has a third switching magnet 64th with a third pole axis 68. The fourth wing carrier 61 has a fourth switching magnet 65 with a fourth polar axis 59. The pole axes 68 and 69 also extend parallel to the switching axis 52. The third pole axis 68 extends coaxially with the first pole axis 66. The fourth polar axis 69 extends coaxially with the second polar axis 67. The polarities of the pole axes 68 and 69 and of the third switching magnet 64, respectively and the fourth switching magnet 65 are in opposite directions to the polarities of the first switching axis 66 and the second switching axis 67 or in opposite directions to the first switching magnet 62 and the second switching magnet 63, respectively.

Each of the wing supports 58 to 61 has bearing surface sections 70 with a concave curvature. Each of the wing supports thus has a constriction, as it were, in the area of the support surface sections 70. As will be explained below, these support surface portions 70 serve as a stop for the switching element 50 to a pin element (in the Fig. 3 not shown) or a respective housing portion radially inwardly bearing the pin element with respect to the indexing axis, for example in the case of a step loss.

Fig. 4 shows an embodiment of a coupling device 80. The coupling device has a disk element 82. The disk element has in the illustrated embodiment at least one, for example, two flats on its outer periphery. The flats 84, 84 'allow a rotationally fixed bearing with respect to the switching axis 52 and at the same time continues to be offset in the axial Direction X with respect to the switching axis 52 allows. Furthermore, a rotationally fixed arrangement of the disc element 82 is provided by the pin elements 90, 91 or by the pin elements 90, 91 overlapping housing sections, which in cooperation with grooves 88, 89 in the disc member 82 a rotationally fixed guide in the axial direction X with respect to the switching axis 52nd provides. In this respect, the flats 84, 84 'are not necessarily provided. The disk element 82 has an inner recess 86. The inner recess 86 corresponds in its cross section to an outer periphery of the sleeve portion 56. The disc member 82 is thus guided with the inner recess 86 on the sleeve portion 56. Consequently, the coupling device 80 is displaceable along the sleeve portion 56 in an assembled state parallel to the indexing axis 52. To avoid frictional forces, a diameter of the inner recess may be larger than a diameter of the sleeve portion. A bearing of the disc element 52 can be provided solely by means of the grooves 88, 89, which will be explained below, and the housing sections supporting the pin elements 90, 91 or the pin elements 90, 91.

Furthermore, the disc element 82 has at least one, in the illustrated embodiment, two circumferential grooves 88 which extend in the axial direction X with respect to the switching axis 52. A peripheral groove or groove 88, 89 is thus a circumferential reduction of the disk element 82 that extends through the entire thickness of the disk element 82 in the axial direction with respect to the indexing axis 52. A pin element 90, 91 is received in each of these circumferential grooves or grooves 88, 89. In the illustrated embodiment, a first pin member 90 is received in the circumferential groove 88 and a second pin member 91 in the circumferential groove 89. Each of the pin members has a recessed area 92. This recessed area 92 with reduced circumferential diameter corresponds to the circumferential grooves 88 and 89. In this way, a pin member 90 and 91 in a circumferential groove 88 and 89 insert such that it is coupled in the axial direction X with the disc member 82 and with this is jointly offset. Radially outwardly, each of the pin members may be attached to, for example, a housing of the clutch assembly 40 (in FIG Fig. 4 not shown) to be supported. In the pin member 90, a portion 101 is marked and on the pin member 91, a portion 102 is marked. The portions 101 and 102, respectively, are those portions of the dome 80 which are in a dome position protrude from a housing of the clutch assembly 40 to provide a non-rotatable coupling. By means of the two sections 101 and 102, this is possible in a form-fitting manner about the indexing axis 52, in that the sections 101 and 102 engage in corresponding recesses of an adjacent element, when they pass through a housing (in FIG Fig. 4 not shown) of the clutch assembly 40 occur.

The disk element 82 has at least one pair 98 of dome magnets 94, 95. In the illustrated embodiment, two pairs 98, 99 of dome magnets 94 to 97 are present. A first pair 98 has a first dome magnet 94 and a second dome magnet 95. A second pair 99 has a third dome magnet 96 and a fourth dome magnet 97. The first dome magnet 94 has a pole axis 104. The second dome magnet 95 has a pole axis 105. The third dome magnet 96 has a third pole axis 106. The fourth dome magnet 97 has a fourth pole axis 107. The pole axes 104 to 107 run parallel to a switching axis 52 or a bore axis of the inner recess 86. The pole axes 104 to 107, the pin elements 90 and 91 thus all extend in the axial direction X. The pole axes 104, 105 of the first coupling magnet 94 and the second Dome magnets 95 are poled in opposite directions. Thus, the pole axes of the first pair 98 are poled in opposite directions. The same applies to the second pair 99. The pole axes 106 and 107 of the third dome magnet 96 and the fourth dome magnet 97 are poled in opposite directions. Accordingly, it follows that the pole axes 104 and 106 of the first and third dome magnets 94, 96 are poled in the same direction. The same applies to the same direction polarity of the pole axes 105 and 107 of the second dome magnet 95 and the fourth dome magnet 97. In particular, the first dome magnet 94 and the third dome magnet 96 are arranged diametrically opposite to each other with respect to the switching axis 52. The same applies in particular to the second dome magnet 95 and the fourth dome magnet 97.

In Fig. 5 the clutch assembly 40 is shown in a uncoupled position 110. In the uncoupling position 110, the switching element 50 is in a first switching position 114.

The clutch assembly 40 has a housing 118. For example, the housing 118 may be the housing of a shaft module or shaft segment, as described in connection with FIG Fig. 2 was explained. However, the housing 118 may also be, for example, a portion of a knob shaft 32 or a portion of a knob 22, 28 itself, as in connection with the Fig. 1 was explained.

In the uncoupling position 110, the pin members 90 and 91 are retracted into the housing 118. Schematically illustrated is an end face 134 of the housing 118. The housing 118 has substantially the shape of a hollow cylinder. In the illustrated embodiment, this hollow cylinder has a circular cross-section. In principle, of course, other cross-sectional shapes are conceivable. Accordingly, there is an end face 134. This end face 134 is to form a coupling surface 36. Accordingly, the pin elements 90, 91 are movable by two recesses in the end face 134. In the Fig. 6 are the pin members 90, 91 positioned so that they protrude from the end face 134, it will be discussed below. In the uncoupling position 110 of Fig. 5 they are retracted into the housing 118, that is, the pin members 90, 91 do not protrude from the end face 134.

The housing 118 has a longitudinal axis 132. The longitudinal axis 132 extends coaxially with the switching axis 52. This is not necessarily the case, however, is given in the present embodiment. Consequently, statements "axial direction" in the direction of the spatial direction X and statements "in the radial direction" in the Y-Z plane.

The clutch assembly 40 has a drive device 128 for driving the clutch assembly 40. The drive device 128 may be, for example, an electric motor, in particular a stepping motor. An energy source, such as an accumulator or a battery may be provided within the drive device 128. Of course, an external power supply is possible. For driving and / or powering the drive device 128, an electrical connection 120 is provided. About electronics is this connection 120 with the Drive device 128 coupled. The electronics have a first part 122 and a second part 123, which are connected by means of a flat conductor 124. The electronics 122, 123 may perform the tasks of driving the drive device 128. In principle, however, it can also verify, for example, incoming authorization requests and thus perform in the sense of evaluation electronics for confirmation of authorization and subsequent actuation of the clutch arrangement 40. Between the first part 122 and the second part 123 in the axial direction, a drilling protection 126 is provided. This avoids drilling and external energizing of the drive device 128. Consequently, for example, in the second part 123 of the electronics, safety-critical circuits can be arranged behind the drill protection.

From the drive device 128, a drive shaft 130 extends. This is rotatably with the according to Fig. 3 designed switching element connected. On the sleeve portion 56 of the switching element 50 is as in Fig. 4 shown coupling device 80 is arranged.

The switching element 50 is in the first switching position. Here, the first wing carrier 58 and the third wing carrier 60 serve their respective bearing surface portions 70 as abutment against a housing portion supporting the first pin member 90 in the event of a step loss, or generally in the event that the switching element is rotated too far. For the second wing carrier 59 and the fourth wing carrier 61, corresponding bearing surface portions serve as abutment on a housing portion supporting the second pin member 91 in the case of step loss, or generally in case the switching element is turned too far. In the Fig. 6 shown second switching position 116 is offset by 90 °. The first switching position 114 and the second switching position 116 are thus precisely defined. In the case of a step loss of the drive device 128, a control of the drive device 128 can thus be restored.

In the in the Fig. 5 The first shift solenoid 62 and the second shift solenoid 63 attractively cooperate with the second clutch solenoid 95 and the fourth clutch magnet 97. Accordingly, the third shift solenoid 64 and the fourth shift solenoid 65 cooperatively repel each other the second dome magnet 95 and the fourth dome magnet 97. As a result, the dome device is attracted and abuts against the first and second wing supports 58, 59. In this way, the first switching position 114 is established, in which the pin elements 90 and 91 are retracted into the housing 118.

It is obvious that in the offset by 90 ° and in the Fig. 6 shown second switching position 116 with respect to the attractive forces and repulsive forces due to the opposite polarity of the first dome magnet 94 and the third dome magnet 96 just inverse conditions. If the switching element 50 is thus rotated from the first switching position 114 into the second switching position 116 by means of the drive device 128 with a corresponding actuation, in particular by 90 °, the magnetic field forces cause the coupling device 80 to move in the axial direction and into contact with the third wing carrier 60 and the fourth wing carrier 61 passes. Consequently, the first pin member 90 projects with the portion 101 and the second pin member 91 with the portion 102 of the end face 134 of the housing 118 out. A positive rotational coupling with an adjoining the end face 134 element is made. Are corresponding recesses in this adjoining element not in registration with the pin members 90 and 91, however, the switching element 50 remains in the second switching position 116, as in the following in connection with the Fig. 7 will be explained in detail. The magnetic field forces, which are still a force on the coupling device 50 in the axial direction, in the Fig. 6 exercise in the positive X direction, thus acting as a kind of energy storage. If the coupling arrangement 40 is rotated, for example by means of an external knob element 22, then the pin elements 90, 91 snap into corresponding recesses of an adjacent component as soon as they lie in coincidence with corresponding recesses in this component and then protrude from the end face 134.

In the second switching position 116, the first wing carrier 58 and the third wing carrier 60 is a housing portion which supports the second pin element 91 as a stop. The second wing carrier 59 and the fourth wing carrier 61 is a housing portion which supports the first pin element 90 as a stop. In the Fig. 6 a portion of the drive shaft 130 can be seen and designated by the reference numeral 130. Furthermore, the housing 118 is designed in particular in two parts. It can be special be cut in the axial direction. In this way can be like in the Figures 5 and 6 shown the individual components of the clutch assembly 40 easy to assemble and ultimately join the two housing halves.

Fig. 7 shows a view in the negative X direction on the coupling device 80 and the switching element 50. Furthermore, the cross sections of the pin members 90 and 91 are shown. The pin elements 90, 91 supporting housing sections are designated by the reference numerals 142 and 144, respectively. In addition, the same elements are identified by the same reference numerals and will therefore not be explained again.

From the representation of Fig. 7 that the clutch assembly 40 in the uncoupling position 110 in the Fig. 5 shows, the switching element 50, the first switching position 114 a. You can see them in the direction of the Fig. 7 These are in particular the third wing carrier 60 and the fourth wing carrier 61. In the first switching position 114, the third wing carrier 60 (and the first wing carrier 58) serves a housing section 142 supporting the pin element 90 as a stop. The fourth wing carrier 61 (and the second wing carrier 59) serves a housing portion 144 supporting the pin element 91 as a stop. Serve as explained above, the concave support surface portions 70th

It is crucial that in the direction of rotation 136 in the first switching position 114, the pole axes 68 and 69 or 66 and 67 are not arranged coaxially with the pole axes 105 and 107, respectively. Rather, the pole axes of the switching magnets 64, 65 and 62, 63 are in the direction of rotation 136 between the pin elements 90, 91 and the pole axes 105 and 107 of the corresponding dome magnets 95 and 97th

In this way, the magnetic field forces ensure that the switching element 50 can not inadvertently rotate from one switching position into the other switching position. The switching element 50 is held in the corresponding position by the drive device 128, which is in particular a stepping motor, and in the case of a step loss with the corresponding contact surface sections 70 pressed on the first pin member 90 and the second pin member 91. The thus defined first switching position 114 is thus held without force on the switching element 50. Energizing the drive means 128 to hold the position is not necessary. The same also applies to the second switching position 116. Overlap sections 138 and 140 are selected to be correspondingly large, so that sufficient magnetic field forces in the axial direction X for displacing the coupling device 50 are maintained.

In the Fig. 8 1 schematically shows a sequence of an embodiment of a method 150 for coupling two elements of a lock cylinder by means of a coupling arrangement. The clutch arrangement has a drive device 128 for rotating a shift element 50 about a shift axis 52 and a coupling device 80. The coupling device 80 is displaceable relative to the switching axis 52 in the axial direction between a coupling position 112 and a Entkuppelposition 110, wherein the switching element 50 or the coupling device 80 has at least one formed as a permanent magnet first switching magnet 62 to 65, wherein a pole axis 66 to 69 of the at least one Shifting magnet 62 to 65 is parallel to the switching axis 52, and wherein the corresponding other of the coupling device 80 and the switching element 50 at least a first pair 98, 99 of dome magnets 94 to 97, wherein each dome magnet 94 to 97 is formed as a permanent magnet, wherein the pole axes 104 to 107 of the dome magnets 94 to 97 of a pair 98, 99 of dome magnets 94 to 97 each extend parallel to the indexing axis 52 and are polarized in opposite directions. In particular, it may be a clutch arrangement, as shown in the FIGS. 3 to 7 is shown.

After starting the method, the clutch assembly 40 is first provided in a first switching position 114 in a step 152, in which the first solenoid with a first dome magnet 94 to 97 of the first pair 98 of dome magnets 94 to 97, cooperates such that the coupling device 80 is set in the uncoupling position 110. This condition is for example in the Fig. 5 shown.

This is followed by a rotation of the switching element 50 about the switching axis 52 in the second switching position 116, so that the first switching magnet 62 with a second dome magnet 95 of the first pair 98 of dome magnets 94 to 97 cooperates such that the coupling device 80 with respect to the switching axis 52 axial direction X moves and is placed in the dome position 112.

The two elements are then coupled and the process can end. For uncoupling, the switching element 50 is correspondingly to be rotated back into the first switching position by means of the drive device 128.
