Abstract

Lock cylinder ( 10 ) for at least an ignition starter switch ( 50 ) or a wheel lock ( 70 ) at a vehicle with a cylinder core ( 12 ) which is at least pivotably received in a cylinder housing ( 11 ) wherein in the cylinder core ( 12 ) at least one blocking element ( 13 ) is provided which prevents a rotation of the cylinder core ( 12 ) in the cylinder housing ( 11 ) in a blocking position and in a releasing position releases a rotation in the cylinder housing ( 11 ) and wherein a key channel ( 12.1 ) extents through the cylinder core ( 12 ) in which a key ( 14 ) is insertable and with which the blocking element ( 13 ) is movable between the blocking position and the releasing position and wherein by the cylinder core ( 12 ) at least two rotation positions ( 0 , III) can be occupied, namely an off-position ( 0 ) and a starting position (III) wherein in the off-position ( 0 ) a key ( 14 ) is insertable and detractable in the key channel ( 12.1 ) and in the starting position (III) at least an appliance, particularly a starter of the vehicle can be switched on.
According to the invention, it is intended that a particularly mechanical resetting block ( 15 ) is existent which prevents a resetting of the cylinder core ( 12 ) at least from the starting position (III) in the off-position ( 0 ) by a particularly simple rotation of the cylinder core ( 12 ).

First claim

1 . Lock cylinder for at least an ignition starter switch or a wheel lock at a vehicle with
a cylinder core which is at least pivotably received in a cylinder housing wherein in the cylinder core at least one blocking element is provided which prevents a rotation of the cylinder core in the cylinder housing in a blocking position and in a releasing position releases a rotation in the cylinder housing and wherein a key channel extents through the cylinder core in which a key is insertable and with which the blocking element is movable between the blocking position and the releasing position and wherein by the cylinder core at least two rotation positions can be occupied, namely an off-position and a starting position wherein in the off-position a key is insertable and detractable in the key channel and in the starting position at least an appliance, particularly a starter of the vehicle can be switched on, characterized in that a particularly mechanical resetting block is existent which prevents a resetting of the cylinder core at least from the starting position in the off-position by a particularly simple rotation of the cylinder core.

2 . Lock cylinder according to claim 1 ,
characterized in that the resetting block prevents a resetting of the cylinder core from a driving position in the off-position, particularly in an ACC-position by a particularly exclusive rotation of the cylinder core.

3 . Lock cylinder according to claim 1 ,
characterized in that the cylinder core comprises at least three stable rotation positions namely an off-position, an ACC-position and a driving position in which the cylinder core is fixed by a fixing element, particularly in a form- and force-fitting manner.

4 . Lock cylinder according to claim 1 ,
characterized in that the cylinder core comprises at least one instable rotation position, namely a starting position which is only achievable against a particularly permanently acting additional turning force.

5 . Lock cylinder according to claim 1 ,
characterized in that the resetting block blocks the cylinder core, particularly in a form-fitting manner, with a simple rotation of the cylinder core from the starting position into the off-position wherein particularly the resetting block blocks the cylinder core from the driving position into the off-position, particularly in the ACC-position.

6 . Lock cylinder according to claim 1 ,
characterized in that the resetting block comprises an adjustable blocking element which in a blocking position mechanically blocks the rotation of the cylinder core from the driving position into the off-position and in the releasing position releases the rotation of the cylinder core into the off-position.

7 . Lock cylinder according to claim 1 ,
characterized in that the resetting block is assembled between the cylinder housing and the cylinder core, particularly between an inner surface shell of the cylinder housing and an outer surface shell of the cylinder core or that the resetting block is assembled in an axial extension of the cylinder core.

8 . Lock cylinder according to claim 1 ,
characterized in that the blocking element of the resetting block is transferable from the blocking position into the releasing position by a longitudinal shift of the cylinder core or by an actuation of the actuation element which mechanically interacts with the blocking element.

9 . Lock cylinder according to claim 1 ,
characterized in that the actuation element is configured as a knob, ring or key.

10 . Lock cylinder according to claim 1 ,
characterized in that the blocking element of the resetting block is transferable from the blocking position into the releasing position by a pressure force or tensile force to a key which is inserted in the key channel of the cylinder core wherein a longitudinal shift of the cylinder core in the cylinder housing is provokable.

11 . Lock cylinder according to claim 1 ,
characterized in that the resetting block comprises a blocking element and a blocking path which at least form-fittingly interacts in the blocking position wherein particularly the form-fit is repealed when the blocking element is in the releasing position.

12 . Lock cylinder according to claim 1 ,
characterized in that the blocking element is assembled in or at the cylinder housing and the blocking path is assembled in or at the cylinder core.

13 . Lock cylinder according to claim 1 ,
characterized in that the blocking element of the resetting block is assembled rigidly to the cylinder housing, particularly in form of a cam with preferably a control element particularly in form of a leading slope and mechanically interacts with at least one longitudinally shiftable coupling element with a blocking path of the resetting block wherein preferably the coupling element is pushable against the cylinder core, particularly by a spring, and is configured torque-proof with the cylinder core.

14 . Lock cylinder according to claim 1 ,
characterized in that between the cylinder housing and the cylinder core a shifting element is intended, particularly in form of a lever element which supports an axial shifting of the cylinder core to the cylinder housing.

15 . Lock cylinder according to claim 1 ,
characterized in that is existent which interacts with the key, particularly the key bit, and a locking bolt of a wheel lock in a way that the locking bolt remains in the releasing position until a withdrawal of the key from the key channel has occurred.

16 . Lock cylinder according to claim 1 ,
characterized in that a blocking element for repeated starting is existent which prevents the cylinder core from being more than once transferable directly from the driving position into the starting position.

17 . Wheel lock for blocking a functionally essential component of a vehicle,
characterized in that according to claim 1 or an ignition starter switch is existent wherein the ignition start switch is in mechanical operative connection with the lock cylinder via a coupling element.

18 . Wheel lock according to claim 17 ,
characterized in that at least a transponder, particularly in form of a coil, is intended in the area of the insertion opening of the key channel wherein at least a data exchange or an energy exchange is transferable to an electronic component of the key.

19 . Wheel lock according to claim 17 ,
characterized in that at least a rotation of the cylinder core by the resetting block, particularly in form of the longitudinally shiftable coupling element is transferable to a control element for controlling a locking bolt or an ignition starter switch.

20 . Method for operation of a lock cylinder or a wheel lock a with at least one ignition starter switch at a vehicle with
a cylinder core which is at least pivotably accepted in a cylinder housing wherein in the cylinder core at least one blocking element is intended which in a blocking position prevents a rotation of the cylinder core in the cylinder housing and in a releasing position releases a rotation in the cylinder housing and wherein a key channel extents through the cylinder core in which a key is insertable and with which the blocking element is movable between the blocking position and the releasing position and wherein by the cylinder core at least two rotation positions can be occupied, namely an off-position and a starting position wherein in the off-position a key is insertable and detractable in the key channel and in t
