Furthermore, the present invention relates to a locking cylinder, in particular a profile cylinder, with one going from one end of the lock cylinder to the other end Shaft, a component arranged essentially concentrically to the shaft and a coupling arrangement for coupling the shaft to the component, the Coupling arrangement at least one coupling element, which is between a coupling position, in which the coupling element interlocks the shaft and the component in the direction of rotation connects, and a decoupling position is displaceable, in which the shaft and the Component are decoupled from each other in the direction of rotation, and has a drive that is configured to move a drive member, thereby closing the coupling member offset.

Finally, the present invention relates to a locking arrangement for a door or the like, with a lock cylinder having a lock bit, a door inside Actuator and an outside actuator.

Such a locking cylinder or locking arrangement are from DE 100 65 155 A1 known.

In general, the present invention relates to the field of lock cylinders and in particular the field of electronic locking cylinders. In the field of locking cylinders the profile cylinders are of particular economic importance. A profile cylinder is a locking cylinder, which is designed to be exchangeable in accordance with DIN 18251 locks prepared for this purpose, e.g. Mortise locks according to DIN 18,251th

A mortise lock according to this DIN standard has a latch and a bolt The latch is usually operated with a pusher, the latch is usually opened with of the profile cylinder moves.

Conventional mechanical profile cylinders are key operated and have in the Usually a number of so-called pin tumblers

For some years there has been a trend towards so-called electronic locking cylinders, where the task of the key completely or partially by a electronic chip is met. In this context, general reference is made at Schloss + Beschlag-Markt, March 1996 edition, pages 70 - 73.

With the electronic locking cylinders, the mechanical actuation of the Riegels continued with the key at the beginning of their development. Before that at these systems, however, the authorization to operate the bolt via one "ID card chip" checked. This is often a passive or active transponder, i.e. a chip on which a special authorization code is stored, which is queried by the respective lock or cylinder. The Queries can be made via contacts (e.g. magnetic stripe reader) or wirelessly (in the Usually by radio).

The next stage of development is the use of mechanical Keys completely dispensed with. For example, in DE 199 23 786 A1 System described in which a lock bit of the profile cylinder via a hollow shaft is rotatably connected to a knob on the inside of the door.

Another shaft extends from the inside of the door knob to an outside of the door Knob. The outside knob is freely rotatable and from the lock bit uncoupled. Only when the user's authorization has been successfully confirmed the hollow shaft is coupled to the through shaft to the outside of the door To connect the pommel to the lock bit. The coupling arrangement provided for this has an electromagnet, which has a rocker armature acts. The magnet armature is between a coupling position and a decoupling position movable.

Another electronic locking cylinder is known from DE 100 65 155 A1 mentioned at the beginning known, the one with a door outside knob connected hollow shaft and has an inner shaft extending therein, both with the lock bit and with is connected to the inside of the door knob.

For coupling the two shafts, a coupling arrangement is provided, one by means of a solenoid axially displaceable slide, which has a drive member forms. With an axial movement of the slide, radially aligned coupling pins offset to the outside and engage in recesses or Openings in the hollow shaft. The inner circumferential recesses are roof-like Flanks delimited from each other, which are able to the dowel pins in the Decoupling position of the slide push radially inwards to the hollow shaft and to decouple the inner shaft from each other.

Another electronic profile cylinder is known from EP 0 999 328 A1. The The inside of the door knob is in turn non-rotatable via a hollow shaft with the lock bit connected. The outside knob is connected to another hollow shaft, the end face by means of a connecting sleeve with the hollow shaft on the inside of the door can be coupled. This is done by a drive in the form of a solenoid.

Another electronic profile cylinder is known from DE 198 34 692 A1. On Knob on the inside of the door is connected to the lock bit via a hollow shaft. The knob on the outside of the door is rotatably connected to an inner hollow shaft that extends up to the knob on the inside of the door. A coupling arrangement for coupling the two hollow shafts are provided inside the knob on the inside of the door.

An electronic profile cylinder is also known from DE 198 24 713 A1. On Knob on the inside of the door is rotatably connected to a hollow shaft that extends up to the Lock bit suffices. In the same way is a door outside knob with a hollow shaft connected, which extends to the lock bit. There is one on the lock bit Rocker swivel mounted as a magnetic anchor. A central hollow shaft penetrates the Profile cylinder and carries two magnetic coils in the area of the lock bit. By means of the Magnetic coil arrangement, the swiveling magnetic armature can either be in one Spend the position in which the lock bit is connected to the inside knob, or in another position in which it is connected to the outside knob.

In general, one strives in the field of electronic profile cylinders, if possible to implement simple mechanical solutions. Furthermore, it is generally advantageous if there is a continuous shaft so that electrical lines from the inside of the door Knobs can easily be moved to the outside knob without, for example To have to provide sliding contacts, such as the profile cylinder EP 0 999 328 A1 is necessary.

In view of the above, it is the object of the present invention to provide a to provide improved locking cylinder or an improved locking arrangement

This object is achieved in accordance with a first aspect of the present invention Solved at the beginning as the first mentioned locking cylinder in that on the drive member and / or at least one permanent magnet is arranged on the coupling member, which is designed to close the coupling element when the drive member moves offset.

This measure allows movement of the drive member to be largely free of friction be implemented in an offset of the coupling element. The necessary power transmission takes place through the magnetic field of the permanent magnet.

Another advantage is usually that the drive is independent of the Positional condition of the clutch assembly can work, regardless of whether the coupling element is in the coupling or uncoupling position.

It is particularly advantageous for the locking cylinder according to the first aspect of the Invention if the component is a lock bit or a housing of the profile cylinder.

This makes it possible to set up the coupling arrangement so that the coupling element establishes a direct positive connection between the shaft and the lock bit. This saves space and components. It's not necessary, to nest several waves into each other.

In the present case, a lock bit means drivers of any shape, including pinions, gears, crossbars, etc.

It is also particularly advantageous if the shaft extends from one end of the Lock cylinder to the other end through shaft. In this embodiment overall, the lock cylinder can be mechanically particularly simple and robust form. It is not necessary to store several rotatable shafts one inside the other.

Furthermore, the above object is achieved by a second aspect of the invention Lock cylinder, as he was initially called second, solved, the component is a lock bit or a housing of the lock cylinder.

By the measure, a continuous shaft of the locking cylinder on the coupling element Coupling directly with the lock bit becomes particularly easy mechanically and robust construction with few components. In particular, it is not necessary to store several rotatable shafts nested in each other. hereby Through-contact between the inside and outside is also simplified. There are no sliding contacts necessary.

The above object is further achieved by the locking arrangement mentioned at the beginning, wherein the door inside actuating element and the door outside actuating element are rotatably connected to each other via a shaft that passes through the lock bit and rotatably connected to the lock bit by means of a coupling arrangement is.

Overall, a mechanically simple locking arrangement is created, which with only provide the full functionality of an electronic profile cylinder for just a few components can.

It is particularly preferred if the locking cylinder of the locking arrangement is a Lock cylinder according to the first or second aspect of the present invention.

It is the lock cylinder according to the second aspect of the present invention of particular advantage if on the drive member and / or on the coupling member at least one permanent magnet is arranged, which is designed for a Movement of the drive member to move the coupling element.

The provision of the permanent magnet enables a coupling or uncoupling process realize particularly low friction. Furthermore, a permanent magnet in mechanically simple and robust design can be integrated.

With the lock cylinders according to both aspects of the present invention, it is from Particularly advantageous if the lock bit has a radial recess in which the Coupling member is mounted radially displaceable.

As a result, the space available in the lock cylinder is optimal exploited. The coupling element is in the uncoupled state in the lock bit and in the coupling position creates a positive connection to the shaft, which preferably is continuously formed.

Overall, it is also advantageous if the drive member is axially movable Slider is formed. As a result, the drive can be of simple construction become.

Furthermore, it is advantageous overall if the drive is designed as an axial drive. An axial drive can be built comparatively easily into a generally elongated one integrate aligned profile cylinder. It is particularly advantageous if the Drive is designed as an electrical solenoid.

According to an alternative embodiment, the drive is an electric motor Spindle drive designed.

According to a further, particularly preferred embodiment, the drive member movable between a coupling position and a decoupling position, the Drive element in the coupling position, the coupling element by means of a first permanent magnet moved to the dome position.

In this embodiment, the first permanent magnet is used to Move the coupling element into the coupling position. As a result, the coupling position be set up with little friction. It is also possible to drive the drive member into the coupling position to move without this directly leading to the coupling element in the Dome position is offset. Rather, this can only take place if, for example by rotating a knob, the coupling element into an opening or the like can come up with. A constant supply of energy is not necessary because the power to Coupling is provided by the permanent magnet.

According to a further preferred embodiment, the drive member in the Decoupling the coupling element by means of a second permanent magnet in the Entkuppelposition. In this embodiment, basically the same applies as for the Embodiment described above, only that the second permanent magnet for active decoupling is formed.

For example, in one embodiment, the coupling element can be in a housing of the profile cylinder, so that the uncoupling position of the coupling member enables the shaft and a lock bit that is firmly connected to it to move freely are. In this embodiment, the shaft is rotationally fixed to the in the coupling position Housing fixed and the lock bit locked.

If, however, the shaft is freely rotatable in the uncoupling position and in the Coupling position is rotatably connected to the lock bit, the second permanent magnet also be used to remove the coupling element from the coupling position actively reset to the uncoupling position. In this embodiment, it is from particularly preferred if the first and second permanent magnets on the drive member are staggered in the direction of movement. It goes without saying that the first and second permanent magnets are installed upside down so that the first permanent magnet, the coupling element in the coupling position and the second permanent magnet forces the coupling element into the uncoupling position.

According to a further, overall preferred embodiment, the shaft is as Hollow shaft formed and the drive member is movably mounted in the shaft.

In this way, the available space in the profile cylinder is optimal Way exploited. Through the design as a hollow shaft is also a direct coupling easy to implement for the lock bit.

It is also advantageous if the coupling element is mounted so as to be radially displaceable. The radial On the one hand, the coupling element can be moved in a structurally simple manner, especially when the coupling element in the lock bit or in the housing of the Lock cylinder is stored.

Furthermore, a form fit between the Realize the shaft and the component or locking bit. So it’s particularly beneficial when the coupling element engages in an opening in the shaft in the coupling position a positive connection between the component and the shaft can be easily namely by providing one or more openings in the shaft.

It is also advantageous if the coupling element has a third permanent magnet having. In this embodiment, it is generally conceivable that only the coupling element has a permanent magnet which therefor when the drive member moves ensures that the coupling element is displaced.

However, it is particularly advantageous if at least one permanent magnet is attached to the Drive member and another permanent magnet is provided on the coupling member, so that the effects of the permanent magnets add up.

It is understood that the above and those yet to be explained Features not only in the specified combination, but also in other combinations or used alone, without the scope of to leave the present invention.

10 shows a schematic illustration of a modification of the embodiment in FIG. 10.

A first embodiment of a locking arrangement according to the invention is shown in FIG. 1 generally designated 10.

The locking arrangement 10 has a locking cylinder 12 which acts as a profile cylinder for a mortise lock S is formed, which is installed in a door T.

An outside of the door is marked with A, the inside with I.

The locking cylinder 12 has a housing 17, in which a shaft 18 along a Longitudinal axis 19 is rotatably mounted.

The shaft 18 is designed as a hollow shaft and is non-rotatable with an inner knob 14 and an outer knob 16 connected.

The locking cylinder 12 is designed as an electronic locking cylinder.

There is an antenna 20 inside the outer knob 16. The antenna 20 is via an antenna line 22 connected to a control device 24 which in the Inner knob 14 is arranged. The antenna line 22 runs through the hollow shaft 18 through and can be designed without sliding contact. In other embodiments the antenna can also be provided in the inner knob.

In this embodiment, a further antenna 20 'is provided in the inner knob 14, which is directly connected to the control device 24.

In an idle state, the shaft 18 with the knobs 14 fixedly attached to it in rotation is 16 freely rotatably mounted in the housing 17. To turn a knob To operate bolt of the lock S, the shaft 18 with a lock bit 32 of the To lock the locking cylinder 12.

Before actuating the clutch arrangement 30, however, in the control device 24 checked whether the person requesting access is authorized or not.

The authorized persons each carry a transponder 26, which has a Radio link 28 with the respective antenna 20 or 20 'in a communication connection stands if the person is close enough to the respective knob 14 or 16.

An authorization code stored in the transponder 26 is transmitted via the antenna 20 or 20 ' read out and forwarded to the control device 24. This checked the authorization code and controls the clutch arrangement 30 when released. If the control device 24 does not release the read authorization code, also the clutch arrangement 30 is not activated. The same applies if a person without transponder 26 on one of the knobs 14 and 16 rotates.

The transponder 26 can be a passive transponder that is Derives energy for sending its authorization code inductively from a read signal, which is transmitted by the antenna 20 or 20 '.

However, more preferred are active transponders 26 that have their own energy supply and also work over longer distances.

Active transponders are often in one for the purpose of saving energy Sleep mode. For example, they can be woken up by turning an idle one of the knobs 14 or 16 and then a magnetic switch, not shown informs the control device 24. The control device 24 then sends a wake-up signal via the respective antenna 20 or 20 'to the transponder 26, which thereupon fed from its own energy supply sends its authorization code that is received and passed on by the respective antenna 20 or 20 '.

In other embodiments, an authorization code may be electrical or magnetic contact (check card with card reader) or entered via keyboard etc. become.

In the prior art, such electronic locking cylinders are common distinguish between the outside A and the inside I. The inner knob is often 14 permanently connected to the locking bit 32 in a rotationally fixed manner.

In the present embodiment, however, a different concept is followed. at this concept, it is usually necessary to unlock it from the inside the lock S to carry an authorized transponder 26.

Furthermore, it is understood that the locking cylinder 12 as an exchange cylinder for conventional ones mechanical profile cylinder is designed, that is, an energy source for supply the control device 24 and a drive 34 to be described, for example housed in the outer knob 16 or the inner knob 14.

Since the locking arrangement 10 is designed so that the actual process of locking or unlocking the lock S by the user's muscular strength, namely by turning the respective knob 14 or 16, the energy consumption is Locking arrangement 10 so low that operation with a single battery is very long periods of time can be guaranteed.

It goes without saying that the lock S also has a latch as a mortise lock can, which may be operated by a door handle (not shown).

The coupling arrangement 30 for coupling the locking bit 32 to the shaft 18 or has an axial drive 34 for uncoupling these components. The axial drive 34 is arranged essentially inside the shaft 18 and has an electromagnetic Solenoid 36 on. The lifting magnet 36 is connected to a rod 38 Drive member connected in the form of a slide 40. The solenoid 36 is for this designed to move the slide 40 in the direction parallel to the axis 19 as it is shown schematically at 41.

In the embodiment shown, the slide has a first permanent magnet 42 and a second permanent magnet 44.

The permanent magnets 42, 44 are arranged offset in the direction parallel to the axis 19 and are fixed with opposite polarity on the slide 40.

While the solenoid 36 within the shaft 18 in a range between Locking bit 32 and the outer knob 16 (or the inner knob 14) is arranged the slider 40 is generally arranged in the area of the locking bit 32.

The lifting magnet 36 is connected to the control device 24 via a line 46 and receives control signals from it.

In Fig. 1, the slide 40 is shown in a decoupling position, in which the second Permanent magnet 44, due to its magnetic field, ensures that the locking bit 32 is uncoupled from the shaft 18. If the solenoid 36 has a suitable control signal receives via line 46, the slide 40 is placed in a coupling position, in which the first permanent magnet 42 ensures due to its magnetic field that the lock bit 32 is coupled to the shaft 18 in a rotationally fixed manner.

For this purpose, there is a coupling member in the form of a driver in the locking bit 32 50 radially displaceable.

In the radial position of the coupling member 50 shown, the coupling member 50 completely accommodated in the lock bit 32.

In the illustrated embodiment, a third permanent magnet is in the coupling member 50 54 provided. In the uncoupled position of the slide 40 shown the north pole of the second permanent magnet 44 the north pole of the third permanent magnet 54 opposite, so that they repel each other. As a result, the coupling member 50 pressed radially outwards into the locking bit 32.

If the solenoid 36 receives a control signal, the slide 40 is in the Coupled position offset at which the first permanent magnet 42 to the coupling member 50 faces. The south pole of the first permanent magnet 42 pulls the north pole of the third permanent magnet 54 so that the coupling member 50 to the slide 40 is drawn.

At least one opening 52 is provided in the shaft 18, into which the coupling member 50 falls due to the magnetic attraction as soon as the shaft 18 through Turning one of the knobs 14, 16 is in the correct rotational position.

It goes without saying that instead of a single opening 52, there are also a plurality of openings can be provided. Then the angular amount by which the shaft 18 is smaller is smaller must be rotated until the coupling member 50 comes into the coupling position.

1. Zum einen wird das Kuppelglied 50 mittels des ersten Permanentmagneten 42 aktiv in die Kuppelposition versetzt. Mittels des zweiten Permanentmagneten 44 wird das Kuppelglied 50 auch aktiv zurückgestellt, in die Entkuppelposition. Demzufolge nimmt das Kuppelglied 50 immer eine definierte Position ein, nämlich entweder die Kuppelposition oder die Entkuppelposition.

2. Der Schieber 40 kann zu einem beliebigen Zeitpunkt von der Entkuppelstellung in die Kuppelstellung bewegt werden. Wenn der Hubmagnet 36 bspw. selbsthemmend ausgebildet ist, ist nach dieser Bewegung keine weitere Energiezufuhr zu dem Hubmagneten 36 notwendig. Durch die Wirkung der Permanentmagnete wird das Kuppelelement 50 dann ohne weiteres in die Öffnung 52, d.h. in die Kuppelposition versetzt, sobald die Öffnung 52 sich in der geeigneten Drehstellung befindet.

3. Dadurch, dass die Kraft zum Bewegen des Kuppelgliedes 50 durch die Magnetfelder der Permanentmagnete hervorgerufen wird, kann der Hubmagnet 36 mit geringer Reibung und folglich geringer Energiezufuhr bewegt werden. Durch die Anordnung des Kuppelgliedes 50 in dem Schließbart 32 wird der in dem Schließzylinder 12 vorhandene Bauraum optimal ausgenutzt.

4. Durch die Maßnahme, dass der Innenknauf 14 und der Außenknauf 16 über eine durchgehende Hohlwelle miteinander verbunden sind, ist die Durchkontaktierung zwischen Innenseite und Außenseite einfach zu realisieren. Dadurch, dass die Kupplungsanordnung 30 mit der Welle 18 mitdrehend ausgebildet sein kann, kann die Durchkontaktierung auch durch den Schieber 40 hindurch erfolgen, ohne dass Schleifkontakte oder Ähnliches vorgesehen werden müssen.

The clutch assembly 30 is advantageous for several reasons:

1. On the one hand, the coupling element 50 is actively moved into the coupling position by means of the first permanent magnet 42. By means of the second permanent magnet 44, the coupling element 50 is also actively returned to the uncoupling position. As a result, the coupling element 50 always assumes a defined position, namely either the coupling position or the uncoupling position.

2. The slide 40 can be moved from the uncoupling position to the coupling position at any time. If the lifting magnet 36 is designed to be self-locking, for example, no further energy supply to the lifting magnet 36 is necessary after this movement. Due to the action of the permanent magnets, the coupling element 50 is then easily moved into the opening 52, ie into the coupling position, as soon as the opening 52 is in the suitable rotational position.

3. Due to the fact that the force for moving the coupling element 50 is caused by the magnetic fields of the permanent magnets, the lifting magnet 36 can be moved with little friction and consequently with little energy input. The arrangement of the coupling element 50 in the locking bit 32 makes optimal use of the space available in the locking cylinder 12.

4. The measure that the inner knob 14 and the outer knob 16 are connected to each other via a continuous hollow shaft, the through-connection between the inside and outside is easy to implement. Because the coupling arrangement 30 can be designed to rotate with the shaft 18, the plated-through hole can also be made through the slide 40 without sliding contacts or the like having to be provided.

It is understood that exactly the two permanent magnets shown on the slide 40 42 and 44 can be provided or distributed in the circumferential direction a plurality of in each case a plurality of first permanent magnets 42 and second permanent magnets 44. This applies in particular when the clutch arrangement 30 is in contact with the shaft 18 rotates and a plurality of openings 52 are provided in the shaft 18. Then pro A first and a second permanent magnet 42, 44 are provided in each case in the opening 52 his.

In general, the two permanent magnets 42, 44 can each be the same size. alternative for this purpose it is also possible for the permanent magnets 42, 44 to have different sizes or provide a differently strong permanent magnetic field. It would be particularly preferred if the first, attracting permanent magnet 42 has smaller dimensions is as the second repulsive permanent magnet 44. According to another Embodiment could also be a permanent magnet somewhat in the radial direction be set back to a different magnetic field with the same dimensions to exert on the coupling element 50.

It goes without saying that instead of an electromagnetic lifting magnet 36 also a Electromotive spindle drive can be used to slide 40 to move axially.

For through-contacting between inside I and outside A, shaft 18 can be used a longitudinal groove can be provided in which one electrical line or several electrical Lines are inserted.

In general, it is also possible to provide only one permanent magnet in the slide 40, that is attractive. In this case, the coupling element 50 could be made of one soft magnetic material in the locking bit 32 radially displaceably and by elastic means (e.g. a spring) in the opposite direction be biased.

According to a further alternative embodiment, only one is on the coupling element 50 Permanent magnet is present, which via elastic means in the uncoupling position is biased. In this case, the slide 40 would be made of a soft magnetic Material so that the permanent magnet in the coupling element against the spring preload is tightened towards the slide.

According to a further embodiment, it is also conceivable for the clutch arrangement 30 to be replaced by a magnetic coil in the area of the locking bit 32, the Solenoid is designed to couple element 50 between the coupling position and the decoupling position.

In general, it is of course also conceivable to use a shaft instead of a continuous shaft 18 to provide, which is non-rotatably connected to the lock bit 32, and another shaft, which is rotatably connected to the outer knob 16 and by means of the coupling arrangement 30 can be coupled with the lock bit 32.

The inside could also be operated with a switch to make it transponder-free To achieve closing.

• der Schließbart 32,
• die Welle 18,
• der Schieber 40 (genauer das Schiebergehäuse zum Aufnehmen der Permanentmagnete),
• bei einem elektromotorischen Antrieb dessen Spindel,
• ggf. eine Außenhülle des Kuppelgliedes um den Permanentmagneten 54 herum.

It is understood that the following components should be made of non-magnetic material:

• the lock bit 32,
• wave 18,
• the slide 40 (more precisely the slide housing for receiving the permanent magnets),
• in the case of an electric motor drive, its spindle,
• if necessary, an outer shell of the coupling element around the permanent magnet 54.

A further embodiment of a locking cylinder 60 is shown in FIGS. 2 and 3 shown, which can be used in a locking arrangement that is the same as the locking arrangement 10 of FIG. 1.

The lock cylinder 60 is structurally and functionally identical to that in many respects Lock cylinder 12 of Fig. 1. The same elements are therefore with the same reference numerals Mistake. In the following, only the differences from the locking cylinder 12 will be discussed received.

The shaft 18 has a radial bore 62 through which the lifting magnet 36 inside the shaft 18 can be fixed, for example by means of a grub screw.

Furthermore, the shaft 18 has three openings 52 which are evenly spaced around the circumference, which are each elongated in the circumferential direction. Between two of the openings 52, a further radial bore 64 is provided, into which a pin (not shown) for Longitudinal guidance of the slide 40 is insertable. For this purpose, the slide 40 a longitudinal groove 66 into which the pin is inserted. The longitudinal groove 66 serves as a guide and has such a length that the pin acts as a stop for defined end positions of the slider 40 can be used.

In Fig. 2 it can also be seen that three corresponding to the openings 52 in the slide Pairs of first and second permanent magnets 42, 44 are provided are.

The housing 17 has a radial slot 68 in the cylindrical part. In corresponding In this way, the shaft 18 has a radial groove 70

Accordingly, the shaft 18 can be axially attached by means of a snap ring or the like fix the housing 17 without restricting the rotational mobility.

On the housing 17 there is also a bore 72 for a forend screw in itself conventionally provided.

The striker 32 has a radial bore 74 that extends from the outer circumference his nose extends to a central bore 76.

In the radial bore 74, the coupling element 50 is mounted so as to be radially movable.

It is understood that after insertion of the coupling element 50, a sealing plug or the like can be provided to prevent the coupling member 50 accidentally slips out of the radial bore 74.

The permanent magnet 54 is inserted into a longitudinal bore of the coupling element 50 is designed as a blind hole.

As a result, the permanent magnet 54 is prevented from directly contacting one of the Permanent magnets 42 or 44 comes into contact and that the coupling element 50 a receives higher stability.

It goes without saying that the coupling element 50 is also closed in the region of the blind bore once the permanent magnet 54 is inserted.

The central bore 76 which passes through the shaft 18 in the assembled state has radial recesses 78 at its axial edge regions. These serve to the lock bit 32 on two plain bearings 80, 82 rotatably, which in corresponding radial recesses of the housing 17 are used.

4, the slide 40 is shown in greater accuracy. You can see that the Slider 40 is designed as a solid, non-magnetic element with a cylindrical shape. A plurality of radial bores 86 have been drilled in the slider 40 to to receive the permanent magnets 42, 44 therein. The longitudinal groove 66 is also milled.

5 shows the locking cylinder 60 in a cross-sectional view in the uncoupling position.

It can be seen that the coupling element 50 due to the repulsive effect of the third Permanent magnets 54 and one of the second permanent magnets 44 in the decoupling position is held. 5 shows that the permanent magnets 42, 44, 54 can be provided with interchanged polarities. So is that shown in Fig. 5 Decoupling position realized by the repulsive forces of two south poles, whereas this is done in Fig. 1 and Fig. 4 by north poles.

5, the shaft 18 can be freely rotated. With in other words, twisting one of the knobs 14, 16 does not result in one The lock bit 32 also turns. The lock S cannot therefore be unlocked or be locked.

FIG. 6 shows a representation corresponding to FIG. 5, with the slide 40 in the Dome position has been moved. Accordingly, the coupling element 50 is one the first permanent magnet 42 has been attracted and positively engages in the opening 52 associated with this permanent magnet 42.

Rotational movements 90 of the shaft 18 are consequently in rotary movements 92 of the locking bit 32 implemented.

It can be seen that the openings 52 each have a length 96 or U in the circumferential direction have that is larger than the outer diameter K of the coupling element. As a result, can secure engagement of the coupling element 50 in the opening 52 even at faster Rotational movement of the shaft 18 can be achieved.

Furthermore, the length 96 of the openings 52 is also greater than the diameter 94 or d of the first and second permanent magnets 42, 44.

The ratio of U / K should be in the range from 1.1 to 3.5, preferably in Range from 1.6 to 2.2 to ensure that on the one hand a safe The coupling element 50 can be engaged in the openings 52 and on the other Side occurs a safe interaction between the magnets 42, 44 and 54 that corresponds to the desired mode of operation.

Due to the fact that the openings 52 are longer than that in the circumferential direction The diameter K of the coupling element 50 also arises when the shaft 18 no more force is applied, a magnetic reset. Because in this State, the permanent magnets 54, 42 try to move axially closer together, see above that the coupling element 50 detaches from the flank of the opening 52 and within the Centered opening 52. As a result, situations are avoided in which the Coupling member 50 adheres in frictional engagement to a side flank of the opening 52, with a Force that may exceed the force of the permanent magnets for decoupling.

Accordingly, the special design of the elongated in the circumferential direction Openings 52 achieved a safe decoupling by the magnetic reset become.

In Fig. 5 it is also shown how the slide 40 in the longitudinal direction by means of a pin 98 is guided, which is inserted into the radial bore 64 and the longitudinal groove 66.

In Fig. 7, a locking cylinder 60 'is shown in a modified version.

The locking cylinder 60 'corresponds in its mode of operation and its structure Lock cylinder 60 and the same elements are provided with the same reference numbers.

Only the differences are discussed below.

In contrast to the locking cylinder 60, the slide 40 'only has first permanent magnets 42 and no second permanent magnets 44.

The coupling element 50 'is reset by means of an elastic device, in a return spring 100 in the illustrated embodiment. Alternatively, there is a compression spring 100 'provided.

The advantage of this embodiment is the smaller number of permanent magnets However, the permanent magnets must be in the coupling position (shown in Fig. 7) constantly overcome the force of the return spring 100.

8 shows a further modified embodiment of a locking cylinder 60 " shown.

The basic structure corresponds to the locking cylinder 60 of Figures 2 to 6; the How it works is somewhat different and is explained below.

In the case of the lock cylinder 60 ', the lock bit 104 is in a conventional manner as Fully solid component executed and fixed to the shaft 18 in a rotationally fixed manner. It does not contain Coupling element.

Instead, a coupling member 108 is radially displaceably mounted on the housing 106. The coupling element 108 is in a corresponding manner to the coupling element 50 with a third permanent magnet 110 provided.

In the uncoupling position shown in Fig. 8, the shaft 18 is common with the Lock bit 104 freely rotatable.

Rotational movements of the knobs 14, 16 consequently lead to unlocking or locking movements of the lock bit 104.

If the slide 40 "is brought into the other position, the coupling element engages 108 into one of the openings 52 and consequently locks the shaft 18 and the locking bit 104 against rotational movements.

As a result, the coupling position for the lock cylinder 60 "is the starting position, so that unauthorized persons cannot operate the locking cylinder 60 ". Only when one Appropriate release takes place using an authorization code, the coupling element 108 moved into the uncoupling position around the shaft 18 and thus the locking bit 104 to unlock.

FIGS. 9a and 9b show a further embodiment of a clutch arrangement 114 shown.

In the decoupling position shown in FIG. 9a there is a soft magnetic Rocker 116 in alignment with shaft 18 and does not engage in a locking bit 32, which is shown schematically.

This position is realized in a stable manner by means of a permanent magnet 118 which points to a End of the rocker 116 acts, the other end against rocking movements by means of a stop 117 is held.

If the permanent magnet 118 is moved under the other end of the rocker 116, is pivoted about an unspecified axis, so that one end of the The rocker engages in a corresponding recess in the locking bit 32 around the shaft 18 and to couple the locking bit 32 positively to one another (FIG. 9b).

A further embodiment of a clutch arrangement 120 is shown in FIGS. 10a and 10b.

In the clutch arrangement 120, a radial slide 122 is mounted on the shaft 18. A permanent magnet 124 is fixed to the radial slide 122.

Another permanent magnet 126 is by means of a stroke drive, for example one electromotive spindle drive 119 displaceable in the axial direction. In Fig. 10a the radial slide 122 by the repulsive forces of the permanent magnets 124, 126 in an opening of the lock bit 32 driven to form fit between the lock bit 32 and shaft 18 to manufacture.

10b, the radial slide 122 is form-fitting in one Deepening of the shaft 18 is added, so that between the shaft 18 and the lock bit 32 no form fit is established.

The radial slide can be disengaged automatically, e.g. by means of roof-like Flanks between the radial slide 122 and the locking bit 32.

11 shows an alternative embodiment of a slide 40 "'.

In this embodiment, the slider is circumferential instead of several distributed first permanent magnet 42 and a plurality of circumferentially distributed second Permanent magnet 44 a disc-like permanent magnet 130 on this is in Aligned longitudinal direction of the axis 19 and acts regardless of the rotational position the north pole of the permanent magnet 130 for decoupling (or coupling) and the South Pole for coupling (or decoupling).

The slide 40 "'is structurally easier to manufacture, but it will not achieved magnetic reset as described above.

12 shows a further alternative embodiment of a slide 40 ^IV .

In this embodiment, the longitudinal groove 66 ″ is in the region of the second permanent magnet 44 a little longer.

In this case, a stable uncoupling position of the slide 40 can also be achieved without self-locking of the lifting drive 36. This is because the stroke H of the slide 40 ^IV is selected such that, in the decoupling position, the permanent magnet 54 is offset by a travel amount Δs with respect to the second permanent magnet 44. As a result, the repelling poles are slightly further apart than if they were directly opposite each other. As a result, a certain repulsive force must be overcome in order to move the slide 40 ^IV from the uncoupling position towards the coupling position.

FIG. 13 shows a modification of the embodiment of FIG. 10, which is generally 120 ' is designated.

The clutch arrangement 120 'has a spring-loaded spring in the decoupling direction Radial slide 122 'on which a permanent magnet 124' is fixed.

An electromotive spindle drive 119 'is a soft magnetic one Element 126 'displaceable in the axial direction.

The soft magnetic element is in the position shown in FIG 126 'in the same axial position as the radial slide 122' and the radial slide 122 'is pulled into an unspecified opening of the shaft 18 against which Force of a compression spring 132.

If the soft magnetic element 126 'is axially displaced (dashed position in Fig. 13), there is no magnetic interaction between the permanent magnet 124 'and the element 126', so that the radial slide 122 'by means of the Compression spring 132 is pulled into the uncoupling position.

In this embodiment, only a permanent magnet is necessary, the travel of the However, drives 119 'are somewhat larger in comparison to the embodiment in FIG. 10. Furthermore, there is no addition of the actuating forces as in the embodiment in FIG. 10 instead of.
