The floor area 23 serves as an abutment for the movement of the actuating knob 3 in push button actuation direction 74 ,

Furthermore, the step mandrel 61 with his first spigot 63 in the second blind hole 37 of the pipe socket 26 screwed. The step mandrel 61 is thus fixed to the control knob 3 connected. This is the base plate 62 outside the push button housing 2 , in particular on the second housing end face 11d , at. This is also the movement of the actuating knob 3 against the pushbutton actuation direction 74 blocked.

The operation button 3 is thus locked or in its locked position. The operation button 3 is parallel to the actuation axis 10 immovable.

The torsion pressure and leg spring 6 is also inside the push button housing 2 arranged. In particular, the Torsionsdruck- and -schenkelfeder 6 at its second end of the spring 6b inside the spring intake groove 21 arranged. In addition, the Torsionsdruck- and -schenkelfeder 6 around the pipe socket 26 of the actuating button 3 and the locking sleeve 5 arranged around. It is spaced from both. In this case, the torsion pressure and -shank spring is supported 6 at its first end of the spring 6a in the direction of the spring axis 69 at the second wall end face 27d of the actuator button housing 25 from. The torsion pressure and leg spring 6 is thus between the actuating button 3 and the push button housing 2 parallel to the spring axis 69 clamped and presses the operating button 3 and the push button housing 2 apart. Respectively. the operation button 3 stands with the torsion pressure and leg spring 6 against the pushbutton actuation direction 74 relative to the push button housing 2 drivable in connection. Respectively. the push-button torsion spring 6 urges the activation button 3 from the push button housing 2 out.

In addition, the first spring wire end 68a the torsion pressure and leg spring 6 inside the spring end receiving slot 76 of the actuating button 3 arranged, and the second spring wire end 68b is inside the spring end receiving hole 76 of the push-button housing 2 arranged. The torsion pressure and leg spring 6 is in the locked state of the push button 1 biased. This allows the operation button 3 , in particular the actuating button housing 25 , relative to the push button housing 2 in unlocking direction 51 only counteracting the force of the torsion pressure and -shank spring 6 around the actuation axis 10 to be turned around. Respectively. the operation button 3 , in particular the actuating button housing 25 , stands with the torsion pressure and leg spring 6 against the unlocking direction 51 relative to the push button housing 2 drivable in connection. The movement of the actuating button 3 , in particular the actuating button housing 25 , contrary to the unlocking direction 51 is also locked by the fact that the locking pin 56 at the first Sperrnuten 18 assigned groove side surfaces 16b issue.

The thigh feather 8th is inside the spring receiving groove 39 of the actuating button 3 arranged. Here is the first spring wire end 73a inside the spring end receiving groove 77 of the actuating button 3 arranged and the second spring wire end 73b is located at the Federendeabstützkante the actuating knob 3 as well as on the second segment side surface 50d of an actuating segment 50 of the cylinder core 4 at. As a result, the leg spring 8th upon rotation of the cylinder core 4 relative to the actuator button housing 25 in the unlocking direction 51 curious; excited.

The locking sleeve 5 is, as already explained, to the pipe socket 26 of the actuating button 3 arranged around. Here are the locking bars 32 of the actuating button 3 inside the groin guide slots 57 arranged. Here are the two strips side surfaces 32b each at the two slot side edges 57b at. As a result, is the operation button 3 with the locking sleeve 5 around the actuation axis 10 non-rotatable in connection.

The last end faces 32a are also at the Schlitzendkanten 57a at. In this position, the locking sleeve 5 from the compression spring 7 crowded, which around the pipe socket 26 around and within the step heel 60 the locking sleeve 5 is arranged. In particular, the compression spring is supported 7 single end on the locking sleeve 5 , in particular on the support surface 60a , and at the other end at the base plate 62 of the step mandrel 61 from.

The locking sleeve 5 also stands for the actuation axis 10 non-rotatable with the push-button housing 2 in connection. These are the locking pins 56 the locking sleeve 5 within the first locking groove 18 arranged.

The locking sleeve 5 thus stands with the compression spring 7 relative to the actuating button 3 against the pushbutton actuation direction 74 drivable in connection.

The lock cylinder core 4 is in a conventional manner within the actuator button housing 25 arranged. In the direction of the actuation axis 10 is the lock cylinder core 4 by means of the locking tumbler 46 immovable with the actuator button housing 25 connected. As long as no matching key in the lock cylinder core 4 is plugged in, is the lock cylinder core 4 around the actuation axis 10 non-rotatable with the actuator button housing 25 in connection, since the platelet tumblers 45 within the locking grooves 48 are arranged.

The operating segments 50 of the lock cylinder core 4 also lie on the locking sleeve 5 at. They are each within a detent recess 78 arranged, locked in this form-fitting manner. In particular, the cylinder core stop surface is located 52 on the second planar surface 59c on, and the cylinder core surface 53 lies on the locking sleeve spiral surface 59d over the entire surface.

The actuation segments pass through this 50 the gaps 34 , In addition, the first segment side surface lies 50c preferably on the first stop surface 34a at. In addition, the operating segments 50 in the wells 35 arranged.

In summary, in the locked state of the push button 1 , as long as thus no matching key in the lock cylinder core 4 is inserted, the lock cylinder core 4 , the actuator button housing 25 , the locking sleeve 5 and the push button housing 2 to each other about the actuation axis 10 non-rotatable. In addition, the operating button 3 also not in push button actuation direction 74 in the push button housing 2 be pressed, so do not be pressed. Also, he can not oppose the push button operation direction 74 relative to the push button housing 2 to be moved. actuating button 3 and push button housing 2 are firmly connected or locked together in the locked state.

To unlock the push button 1 Now a matching key in push button actuation direction 74 in the lock cylinder core 4 plugged in. This will cause the platelet tumblers 45 from the locking grooves 48 out into the interior of the lock cylinder core 4 moved in. Now the lock cylinder core 4 relative to the actuating button 3 by means of the key in the unlocking direction 51 to be turned around.

During the rotation of the lock cylinder core 4 slides the cylinder core surface 53 on the locking sleeve spiral surface 59d so along, that the locking sleeve 5 relative to the actuating button 3 in push button actuation direction 57 is moved ( 16 ). This will cause the two locking pins 56 the locking sleeve 5 each from the first locking groove 18 moved out ( 17 ). The compression spring 7 is compressed and stretched. Also the leg spring 8th is due to the rotation of the lock cylinder core 4 relative to the actuator button housing 25 curious because the spring wire ends 73a ; 73b be pushed apart.

Once the locking pin 56 outside the first locking grooves 18 are arranged, the locking sleeve 5 and thus also the actuating button housing 25 relative to the push button housing 2 in unlocking direction 51 to be turned around. Because the second segment side surfaces 50d to the second stop surfaces 34b the spaces between 34 are triggered, when continuing the key rotation or rotation of the lock cylinder core 4 in unlocking direction 51 the entire operating button 3 together with the locking sleeve 5 taken. The rotation is maximum until the locking pin 56 at the second Sperrnuten 19 assigned groove side surfaces 16b the locking sleeve receiving grooves 16 nudge.

When turning the actuating knob 3 in unlocking direction 51 relative to the push button housing 2 becomes the torsion pressure and leg spring 6 curious because the spring wire ends 68a ; 68b be forced apart in the circumferential direction. The rotation of the locking sleeve 5 relative to the push button housing 2 also causes the pin spiral surfaces 56d the locking pin 56 at the web spiral surfaces 17a the barrier webs 17 slide along 18 ). This causes an additional or simultaneous or superimposed linear movement of the locking sleeve 5 in push button actuation direction 74 relative to the actuating button 3 and to the push-button housing 2 , In particular, this causes the locking sleeve 5 from the actuation segments 50 of the cylinder core 4 is spaced ( 19 ). This locks the locking pins 56 as soon as they are in the direction of the actuation axis 10 seen in alignment with the second locking grooves 19 are arranged, driven by the force of the compression spring 7 partly in the second locking grooves 19 one ( 20 ). This is the locking sleeve 5 again about the actuation axis 10 non-rotatable in the push-button housing 2 arranged.

The locking sleeve 5 However, it can only engage as far as the locking sleeve spiral surface 59d on the cylinder core surface 53 abuts. In this position are the locking pins 56 not yet completely within the second locking groove 19 arranged.

The lock cylinder core 4 is in its actuated limit stop. As a result, the key is next released by the operator. As a result, the lock cylinder rotates 4 automatically, in particular driven by the leg spring 8th , contrary to the unlocking direction 51 back to its non-actuated home position.

When turning back the lock cylinder core 4 slides the cylinder core surface 53 again, but opposite to before, on the locking sleeve spiral surface 59d along until the surfaces 53 ; 59d again together over the whole area. Because of this, the locking sleeve 5 , driven by the force of the compression spring 7 against the pushbutton actuation direction 74 relative to the actuating button 3 , in particular to the lock cylinder core 4 , and the push button housing 2 moved so that the locking pin 56 completely in the second locking grooves 19 lock in place ( 25 ).

After turning back the lock cylinder core 4 or during that time the key is then removed from the lock cylinder core by the operator 4 pulled out.

The operation button 3 is now in the unlocked, unactuated state. Because the locking bars 32 are now in the direction of the actuation axis 10 in alignment with the passage grooves 20 of the push-button housing 2 arranged ( 22 . 23 ). The movement of the actuating button 3 in push button actuation direction 74 is therefore no longer locked.

Will the operating button 3 operated by the operator by pressing in push-button actuation direction 74 in the push button housing 2 is pressed, he takes the locking sleeve 5 With. This will be the locking pin 56 the locking sleeve 5 again from the second locking grooves 19 of the push-button housing 2 pressed out. With the control knob 3 is also the step mandrel 61 in the direction of the pushbutton actuation direction 74 relative to the push button housing 2 postponed. This will be the actuating mechanism 101 the lock mechanics operated in a conventional manner such that the lock 100 is unlocked ( 26 ).

During the operating stroke or immediately after releasing the operating button by the operator at the beginning of the return stroke of the operating knob 3 together with the locking sleeve 5 already automatically, in particular by the force of the torsion pressure and -shank spring 6 , as far as the direction of unlocking 51 Turned back until the locking bars 32 at the first groove side surfaces 20b the passageways 20 nudge ( 27 ). The movement of the actuating button 3 and the locking sleeve 5 against the unlocking direction 51 is therefore limited or the return angle is limited or the movement is interrupted. This intermediate position is a prerequisite that during the return stroke of the actuating knob 3 against the pushbutton actuation direction 74 an automatic or automatic locking takes place. In particular, it is a prerequisite for the operation button 3 can not return to its unlocked position:
The locking sleeve 5 is turned back so far until the locking pin 56 in the direction of the actuation axis 10 in alignment with the barrier bars 17 are arranged ( 26 ) or the locking pin 56 no longer in alignment with the second locking grooves 19 are.

In the actuated position of the actuating knob 3 is the torsion pressure and leg spring 6 in the direction of its spring axis 66 compressed. After releasing the control knob 3 by the operator, the operating button snaps 3 therefore automatically, in particular driven by the Torsionsdruck- and -schenkelfeder 6 , contrary to the push button actuation direction 74 back until the pin turn surfaces 56d at the web spiral surfaces 17a nudge ( 28 ). That is, during the return stroke of the operation knob 3 hit the surfaces 56d ; 17a each other.

Due to this, the movement of the locking sleeve 5 against the pushbutton actuation direction 74 interrupted, whereas the actuating button 3 continue counter to the push button actuation direction 74 emotional. The operation button 3 thus moves relative to the locking sleeve 5 continue counter to the push button actuation direction 74 , The operation button 3 moves so far against the push button actuation direction 74 until the step mandrel 61 on the push button housing 2 abuts. The step mandrel 61 thus forms the abutment for the return stroke of the actuating knob 3 , The locking bars 32 then again completely outside the through-grooves 20 of the push-button housing 2 arranged or from the Durchgangsnuten 20 drove out.

Once the locking bars 32 again completely outside the through-grooves 20 of the push-button housing 2 are arranged ( 29 ), becomes the operation button 3 automatically, in particular driven by the torsion compression spring 6 , contrary to the unlocking direction 51 turned back to its original position, in which the locking bars 32 in alignment with the floor surface 23 are arranged. The locking sleeve 5 is taken along.

Powered by the force of the compression spring 7 returns the locking sleeve 5 automatically against the push button actuation direction 74 back to starting position. In this case slide due to the superimposed rotational movement of the locking sleeve 5 the pin turn surfaces 56 at the web spiral surfaces 17a along until the locking pins 56 back into the first locking grooves 18 engage.

The push button 1 is thus back in its locked position and can only be operated again by inserting a suitable key. The inventive push-button 1 ensures a high degree of protection against unauthorized opening of the vehicle door, hood or flap. Because by the fact that the push button 1 during the return stroke of the actuating button 3 automatically locked, so without actuation by means of the key, the push button must 1 not be actively locked. This is done automatically and purely mechanically, preferably by spring forces and coordinated surfaces, in particular helical surfaces. In particular with hoods, in particular bonnets, and flaps of a vehicle, this is an important safety aspect in order to avoid accidents.

In the context of the invention, it is also the case that instead of the lock cylinder core, a cylinder core is present, which by means of a tool, for. B. a screwdriver or wrench is rotatable. For this purpose, the cylinder core on corresponding connection elements. In this case, the cylinder core is basically rotatable in the unlocking due to lack of platelet tumblers, but only against the force of the leg spring, so that the push button thereby remains in its locked position.
