Further advantageous embodiments of the invention are in the Be spelling, the figures and the subclaims.

In the following the invention is exemplified with reference to the Described drawing, the only figure of a partial axial section Embodiment of an attached to a door leaf, fiction, ge system shows.

The locking system according to the invention shown in the figure comprises egg NEN arranged on an inside of a door leaf 80 inside knob 10 and an outside knob 50 . The knobs 10 , 50 each include a housing 11 , 51 made of plastic, which is open on its side facing away from the door leaf 80 , and which is also surrounded by a cover cap 13 , 53 , also made of plastic. The cover caps 13 , 53 each extend up to a rosette 15 , 55 connected to the door leaf 80 .

The housing 11 of the inner rotary knob 10 is rotatably connected to a sleeve 12 made of metal, which extends through a pre-arranged in the door leaf 80 lock 90 and terminates within the door leaf 80th A rotatably connected to the housing 51 of the outer knob 50 , also made of metal hollow shaft 52 extends through the sleeve 12 of the inner knob 10 through into the interior of the housing 11 .

The axial fixation of the sleeve 12 and the shaft 52 - and thus of the two knobs 10 , 50 - is carried out by fixing springs 17 , 57 of the rosettes 15 , 55 , which are detachable by a tool in the fixing recesses formed on the sleeve 12 and the shaft 52 18 , 58 intervene. With regard to this fixation, reference is made to the German utility model 2 95 11 547 registered on July 19, 1995.

On the sleeve 12 of the inner knob 10 , a three-part, consisting of a cylinder adapter 34 , a closing element 30 and a bearing sleeve 36 be arranged adapter unit.

The cylinder adapter 34 made of metal has in a plane par allel to the door leaf 80 a cross-sectional shape that that of a conventional, z. B. corresponds as a profile, round or oval cylinder formed locking cylinder. The cylinder adapter 34 is inserted into corresponding openings in the door leaf 80 and the lock 90 and is thus arranged in the lock 90 in a rotationally fixed manner.

The locking element 30, which is also made of metal, comprises a sleeve-shaped bearing section 31 , to which a locking bit 33 is formed for actuating a bolt, not shown, of the lock. The closing beard 33 is flush with the axial end of the sleeve-shaped bearing section 31 facing the inner rotary knob 10 in the arrangement according to the figure. The closing element 30 consequently has an asymmetrical structure.

In the resin-made bearing sleeve 36 of the cylinder adapter 34 and the closure element 30 are mutually rotatably arranged in such a way that the closing element 30 is located with its bearing portion 31 between two annular bearing portions 35 of the cylinder adapter 34th In the cylinder adapter 34 , a recess 38 for the locking beard 33 is provided, which allows the locking element 30 to be rotated relative to the cylinder adapter 34 by 360 °. The cylinder adapter 34 is consequently also constructed asymmetrically.

The position of the axis of rotation of the locking unit according to the invention - about what che the knobs 10 , 50 , the sleeve 12 , the shaft 52 and the locking element 30 can be rotated - is thus through the cylinder adapter 34 and the corresponding openings in the door leaf 80 and in the lock 90th fixed.

The sleeve 12 of the inner rotary knob has a guide slot 19 which extends in the axial direction and is formed as an incision in the sleeve wall starting from the free end of the sleeve 12 . The Füh approximately slot 19 cooperates with a guide and actuating rib 32 of the closing element 30 , which is formed on the opposite side of the lock bit 33 on the inner wall of the sleeve-shaped Lagerab section 31 and extends in the axial direction over its entire length GE.

In the bearing sleeve 36, a slit 37 is formed, the outgoing than 36 incision is formed from the left in the figure axial end of the bearing sleeve. Consequently, the bearing sleeve 36 also has an asymmetrical structure. The guiding and actuating rib 32 of the closing element 30 protrudes through the slot 37 of the bearing sleeve 36 so far into the aligned with the slot 37 guide slot 19 of the inner rotary knob sleeve 12 that the guide and actuating rib 32 approximately flush with the inner wall of the Inner knob sleeve 12 completes.

Within the housing 11 of the inner knob 10 , a cylindrical coupling unit 40 is arranged, in which a guide channel 42 is ausgebil det. The free end portion of the shaft 52 of the outer knob 50 , with which the shaft 52 projects into the guide channel 42 , is flattened and thus has a non-circular cross-section, which corresponds to the free cross section of the guide channel 42 , so that the shaft 52 - and there with the outer rotary knob 50 - non-rotatably connected to the coupling unit 40 .

By a stop 56 , which is formed on the outer knob 50 facing the end of the flattened area, the maximum insertion depth of the shaft 52 is fixed in the guide channel 42 .

A connector designed as a connector 24 is axially displaceable within the Füh approximately 42 channel and inserted into a socket member 59 that rotatably and axially immovably connected to the shaft 52 of the Au ßendknopfs 50 . The cross section of the connecting element 24 corresponds to the non-circular cross section of the shaft 52 and there with the free cross section of the guide channel 42 , in which the connecting element 24 can consequently not rotate.

The guide channel 42 of the coupling unit 40 proceeds from the leaf door 80 facing away from end face in a bore 25 smaller diam sers over which a cap 13 formed in the bore 13 a leading to the outside.

Via a through the hollow shaft 52 extending electrical connec tion line 22 , which comprises individual signal and supply lines, the socket element 59 is connected to a angeordne in the outer knob 50 , in the figure by its cover 53 hidden code input unit connected. The code input unit is designed as a receiver unit of a transponder unit and is connected via the connection element 24 to a control and actuation unit of the transponder unit, which is integrated in the coupling unit 40 . In this way, the coupling unit 40 is part of the transponder unit.

In the outer knob 50 space is provided for a battery unit or a rechargeable battery unit for supplying power to the locking system.

The control and actuation unit includes, in addition to electronic components, a motor with which a pin-shaped, not shown in the figure, offset parallel to the axis of rotation of the clamping unit and extending with actuators can be actuated. The connecting line 22 serves to supply the motor with voltage.

By means of the motor, the driver can be moved back and forth between a driving position and a free-wheel position, the driver being engaged in its driving position and disengaged from recesses 14 in its free-wheeling position.

The recesses 14 are each provided in the form of a bore in a one piece with the sleeve 12 of the inner knob 10 entrainment disk 16 . A plurality of such recesses 14 are arranged distributed around the edge of the driving plate 16 in the circumferential direction. The drive plate 16 forms an end face region of the housing 11 and a contact surface for the clutch unit 40 arranged therein.

Consequently, by means of the motor, the clutch unit 40 can optionally be brought into a driving or in a freewheeling state, the clutch unit 40 being in the driving state when in one of the recesses 14 in the driver, which rotates the inner rotary knob 10 and thus the locking bit 33 by means of the outer knob 50 allowed.

In the clutch unit 40 , a motion sensor, not shown, is arranged, which is designed to detect a rotational movement of the clutch unit and is used to block an axial movement of the driver between its driving and free-running state by providing a corresponding signal, while the clutch unit turns.

The locking system according to the invention works as follows:
The sleeve 12 of the inner knob 10 is inserted with the adapter unit plugged into the openings provided in the door leaf 80 and the lock 90 until the fixing spring 17 of the rosette 15 snaps into the fixing recess 18 of the sleeve 12 .

This allows, on the one hand, the asymmetrical structure of the adapter unit consisting of the cylinder adapter 34 , the closing element 30 and the bearing sleeve 36 , these optionally before insertion into the lock 90 either with the locking bit 33 or the opposite axial end of the closing element 30 in front to insert the sleeve 12 of the inner rotary button 10 .

As a result, the locking system according to the invention can be used on doors in which the lock 90 is arranged close to one of the side surfaces of the door leaf 80 , regardless of whether it is the inside or the outside thereof.

In the arrangement according to the figure, the door leaf 80 on the inner knob 10 facing side of the lock 90 is thinner than on the opposite side, so that the closing element 30 is arranged on the sleeve 12 such that it with its lock bit 33 the inside of the door is facing.

The adapter unit is then brought into the desired axial position on the sleeve 12 , in which the locking bit 33 can actuate the bolt of the lock 90 .

For this purpose, the adapter unit can simply be pushed back and forth on the sleeve 12 , the bearing sleeve 36 sliding along the outer wall of the sleeve 12 and the guiding and actuating rib 32 of the closing element 30 being guided through the guide slot 19 of the sleeve 12 .

Then the shaft 52 of the outer knob 50 through the sleeve 12 through and with its free end in the guide channel 42 of the hitch be 40 unit inserted into it until the fixing spring 57 of the rosette 55 snaps into the fixing recess 58 of the shaft 52 .

In order to produce the electrical plug-in connection between the mounted at the free end of the shaft 52 sleeve member 59 and disposed in the guide channel 42 connecting element 24, the terminal can element 24 acted upon from outside with a counter-holding tool who to, the through hole 13 a of the cap 13 and the Bore 25 of the coupling unit 40 can be inserted.

The correct relative alignment of the socket member 59 and the on circuit element 24 is guaranteed by the non-circular cross-sections of the shaft 52 , the guide channel 42 and the connecting element 24 , which allow the insertion of the shaft 52 into the sleeve 12 only with correct relative relative angular orientation .

The stop 56 of the shaft 52 prevents the shaft 52 from penetrating too far into the coupling unit 40 when the door leaf thicknesses are too small and the connection element 24, for example, presses against a circuit board or other electronic components, which in the region of the door leaf 80 pointing away from the coupling unit 40 are arranged.

The axial displaceability of the adapter unit on the sleeve 12 , the possi bility of turning the asymmetrically constructed adapter unit and the telescopic insertion of the sleeve 12 and the shaft 52 make it possible to adapt the locking system according to the invention both to different door leaf thicknesses and to different axial positions of the lock 90 inside the door leaf 80 .

This adjustment becomes easy in the manner described above when assembling the locking system during its installation made on the door leaf, whereby none of the components of the locking system for this adaptation must be structurally changed in any way.

By rotating the inner rotary knob 10 is transmitted via the formed in the sleeve 12, guide slot 19 and the guide and Betätigungsrip pe 32 of the locking element 30 taken along the closing element 30 and entrained in this way together with the tätigungsrippe also on the guide and Be 32 bearing sleeve 36 from the Zylin deradapter 34 rotated. About the lock bit 33 , the bolt of the lock 90 can be operated in this way and the door can be unlocked and locked at any time by means of the inner rotary knob 10 .

The trained as a receiver unit of the transponder unit code input unit in the outer knob 50 responds to an authorization code, for example in the form of a radio or induction signal, which is transmitted to the receiver unit via a transmitter, which can be designed in any manner.

The transmitter can be an authorized person z. B. in the form of a Carry a credit card with you.

Upon receipt of the authorization code, the motor of the clutch unit 40 is actuated by the receiver unit via the connecting line 22 in order to change from the freewheeling state to the driving state, ie in order to either enable or prevent actuation of the bolt of the lock 90 via the external rotary knob 50 .

The motion sensor of the clutch unit 40 designed to detect a rotary movement ensures that the driver does not move from its driver position to the freewheeling position or vice versa as long as the clutch unit 40 is rotating.

This is advantageous, for example, if the locking system is provided with an automatic timer, which ensures that the driver is automatically moved back into its free-running position after a predeterminable period of time following the transfer of the coupling unit 40 into the driving position. This automatic decoupling of the outer knob 50 and the inner knob 10 can then be prevented by the movement sensor when an authorized person actuates the outer knob 50 beyond the end of this period.

In the above-described embodiment of the locking system according to the invention, an electrical signal path in the form of the connecting line 22 thus extends through the hollow shaft 52 of the outer rotary knob 50 . Alternatively, an optical signal path can also be provided in the form of light guides, for example.

Instead of the transponder unit described can in the fiction any code entry unit, those for converting a coded signal into electrical or optical Si gnale is able to control together with one by means of these signals and thus between a take-away and a freewheel reversible clutch unit. The code gift unit could be used, for example, to distinguish fingerprints press or other individualizing body characteristics and only reverse the clutch unit if her fingerprint - or any other physical characteristic - is one authorized person is identified.
