Abstract

A lock, in particular for a two-wheeler, comprises: a lock body; a hoop that is movable between an open position and a closed position; a latch that is movably supported at the lock body between a locked position in which it blocks the hoop in its closed position against a departure from the closed position and an unlocked position in which it releases the hoop; a sensor for detecting the latch position; and a movably supported lever. A coupling section of the lever is movement-coupled to the latch here. In addition, the lever is supported such that on a movement of the coupling section, a deflection section spaced apart from the coupling section carries out a movement that is greater in comparison therewith, with the sensor detecting the position of the deflection section of the lever to detect the latch position.

First claim

What is claimed is:

1. A lock ( 11 ) comprising
a lock body ( 13 );
a hoop ( 17 ) that is movable between an open position and a closed position;
a latch ( 19 ) that is movably supported at the lock body ( 13 ) between a locked position in which it blocks the hoop ( 17 ), while the hoop ( 17 ) is in the closed position, against a departure from the closed position, and an unlocked position in which it releases the hoop ( 17 ); and
a sensor ( 41 ) for detecting the latch position;
wherein the lock further comprises a movably supported lever ( 33 ), with a coupling section ( 35 ) of the lever ( 33 ) being movement-coupled to the latch ( 19 );
with the lever ( 33 ) being supported such that on a movement of the coupling section ( 35 ), a deflection section ( 37 ) of the lever ( 33 ) spaced apart from the coupling section ( 35 ) carries out a movement that is larger than the movement of the coupling section ( 35 );
and with the sensor ( 41 ) detecting the position of the deflection section ( 37 ) of the lever ( 33 ) to detect the latch position;
wherein the deflection section ( 37 ) magnetically cooperates with the sensor ( 41 );
wherein the deflection section ( 37 ) has a permanent magnet ( 43 ) and the sensor ( 41 ) is configured as a magnetic sensor.

2. A lock in accordance with claim 1 , wherein the lever ( 33 ) is pivotably supported about a pivot point ( 39 ).

3. A lock in accordance with claim 2 , wherein the pivot point ( 39 ) is provided between the coupling section ( 35 ) and the deflection section ( 37 ).

4. A lock in accordance with claim 1 , wherein the coupling section ( 35 ) is provided at a first end of the lever ( 33 ) and the deflection section ( 37 ) is provided at a second end of the lever ( 33 ) opposite the first end.

5. A lock in accordance with claim 1 , wherein the hoop ( 17 ) is at least partly arranged within the lock body ( 13 ) and wherein the latch ( 19 ) and the lever ( 33 ) are arranged completely within the lock body ( 13 ).

6. A lock in accordance with claim 1 , wherein the sensor ( 41 ) is configured as a Hall sensor or as a magnetic field sensor; and/or wherein the sensor ( 41 ) is configured for a three-dimensional magnetic detection.

7. A lock in accordance with claim 1 , wherein the lock comprises an inner housing that is arranged within the lock body ( 13 ), with the sensor ( 41 ) being arranged within the inner housing and the lever ( 33 ) being arranged outside the inner housing.

8. A lock in accordance with claim 7 , wherein the inner housing is closed fully around its periphery.

9. A lock in accordance with claim 1 , wherein the lever ( 33 ) is supported such that it has a single degree of freedom.

10. A lock in accordance with claim 1 , wherein the lock comprises a drive motor ( 29 ) for moving the latch ( 19 ).

11. A lock in accordance with claim 10 , wherein the lever ( 33 ) is aligned substantially in parallel with the drive motor ( 29 ).

12. A lock in accordance with claim 1 , wherein the hoop ( 17 ) has a first engagement recess ( 21 ) into which the latch ( 19 ) can engage when the hoop ( 17 ) is in the closed position to block the hoop ( 17 ) against a departure from the closed position.

13. A lock in accordance with claim 12 , wherein the hoop ( 17 ) has a second engagement recess ( 27 ) into which the latch ( 19 ) can engage when the hoop ( 17 ) is in the open position to block the hoop ( 17 ) against a departure from the open position.

14. A lock in accordance with claim 1 , wherein the latch ( 19 ) is preloaded against the hoop ( 17 ) so that it contacts a contour ( 25 ) of the hoop ( 17 );
and wherein the contour ( 25 ) of the hoop ( 17 ) is configured such that, as a consequence of the preload, the latch ( 19 )
adopts its locked position in the closed position of the hoop ( 17 );
adopts its unlocked position in positions of the hoop ( 17 ) that are between the closed position and the open position of the hoop ( 17 ); and
adopts a securing position that differs from the locked position and from the unlocked position in the open position of the hoop ( 17 ).

15. A lock in accordance with claim 14 , wherein the securing position of the latch ( 19 ) lies between the locked position and the unlocked position.

16. A lock in accordance with claim 1 , wherein the hoop ( 17 ) has a first engagement recess ( 21 ) into which the latch ( 19 ) can engage when the hoop ( 17 ) is in the closed position to block the hoop ( 17 ) against a departure from the closed position; wherein the hoop ( 17 ) has a second engagement recess ( 27 ) into which the latch ( 19 ) can engage when the hoop ( 17 ) is in the open position to block the hoop ( 17 ) against a departure from the open position;
wherein the latch ( 19 ) is preloaded against the hoop ( 17 ) so that it contacts a contour ( 25 ) of the hoop ( 17 ), wherein the contour ( 25 ) of the hoop ( 17 ) is configured such that, as a consequence of the preload, the latch ( 19 )
adopts its locked position in the closed position of the hoop ( 17 );
adopts its unlocked position in positions of the hoop ( 17 ) that are between the closed position and the open position of the hoop ( 17 ); and
adopts a securing position that differs from the locked position and from the unlocked position in the open position of the hoop ( 17 );
wherein the contour ( 25 ) of the hoop ( 17 ) has the first engagement recess ( 21 ) and the second engagement recess ( 27 ) so that, as a consequence of the preload, the latch ( 19 )
engages into the first engagement recess ( 21 ) in the closed position of the hoop ( 17 ), with the locked position of the latch ( 19 ) being defined by the depth of the engagement; and
engages into the second engagement recess ( 27 ) in the open position of the hoop ( 17 ), with the securing position of the latch ( 19 ) being defined by the depth of the engagement.

17. A lock in accordance with claim 1 , wherein the lock ( 11 ) is configured to selectively block a wheel of a two-wheeled vehicle.

18. A lock ( 11 ) comprising
a lock body ( 13 );
a hoop ( 17 ) that is movable between an open position and a closed position;
a latch ( 19 ) that is movably supported at the lock body ( 13 ) between a locked position in which it blocks the hoop ( 17 ), while the hoop ( 17 ) is in the closed position, against a departure from the closed position, and an unlocked position in which it releases the hoop ( 17 ); and
a sensor ( 41 ) for detecting the latch position;
wherein the lock further comprises a movably supported lever ( 33 ), with a coupling section ( 35 ) of the lever ( 33 ) being movement-coupled to the latch ( 19 );
with the lever ( 33 ) being supported such that on a movement of the coupling section ( 35 ), a deflection section ( 37 ) of the lever ( 33 ) spaced apart from the coupling section ( 35 ) carries out a movement that is larger than the movement of the coupling section ( 35 );
and with the sensor ( 41 ) detecting the position of the deflection section ( 37 ) of the lever ( 33 ) to detect the latch position;
wherein the deflection section ( 37 ) magnetically cooperates with the sensor ( 41 );
wherein the lock comprises an inner housing that is arranged within the lock body ( 13 ), with the sensor ( 41 ) being arranged within the inner housing and the lever ( 33 ) being arranged outside the inner housing.

19. The lock in accordance with claim 18 , wherein the sensor ( 41 ) is configured as a Hall sensor or as a magnetic field sensor; and/or wherein the sensor ( 41 ) is configured for a three-dimensional magnetic detection.
