Abstract

A padlock comprises a lock body, a hoop which is displaceably held at the lock body, a cylinder core into which at least one core pin is inserted and which is supported directly in a reception opening rotatable about a cylinder axis in order selectively to lock or release the hoop at the lock body, and a tumbler housing into which at least one housing pin is inserted and which is received in a fixed position in the lock body.

First claim

The invention claimed is:

1. A padlock comprising:
a lock body;
a hoop, the hoop being displaceably held at the lock body;
a cylinder core into which at least one core pin is inserted and which is rotatably supported about a cylinder axis in direct contact with a reception opening of the lock body in order selectively to lock or release the hoop at the lock body, wherein the padlock does not comprise a cylinder housing for the cylinder core; and
a tumbler housing that is received as a separate element from and in a fixed position relative to the lock body and into which at least one housing pin is inserted.

2. The padlock in accordance with claim 1 , in which the tumbler housing is pressed in the lock body.

3. The padlock in accordance with claim 1 , further comprising a securing pin to hold the cylinder core axially fixedly in the lock body.

4. The padlock in accordance with claim 3 , in which the securing pin is inserted in a pin passage of the tumbler housing extending in parallel with the at least one housing pin.

5. The padlock in accordance with claim 3 , in which the securing pin is inserted in a throughgoing pin passage of the tumbler housing.

6. The padlock in accordance with claim 3 , in which the securing pin is arranged behind the at least one housing pin in the key insertion direction.

7. The padlock in accordance with claim 3 , in which the cylinder core is axially fixedly held in the lock body only by the securing pin.

8. The padlock in accordance with claim 3 , in which the securing pin engages into a groove of the cylinder core extending in the peripheral direction with respect to the cylinder axis.

9. The padlock in accordance with claim 8 , in which the capability of being rotated of the cylinder core is restricted to an angular range of less than 180°, in that the groove only extends over a corresponding angular range of the periphery of the cylinder core.

10. The padlock in accordance with claim 9 , in which the capability of being rotated of the cylinder core is restricted to an angular range of less than 120°.

11. The padlock in accordance with claim 9 , in which the capability of being rotated of the cylinder core is restricted to an angular range approximately 110°.

12. The padlock in accordance with claim 8 , in which the groove is arranged behind the at least one core pin in the key insertion direction.

13. The padlock in accordance with claim 1 , in which the reception opening is configured as a reception borehole and the lock body has a further reception opening for receiving the tumbler housing.

14. The padlock in accordance with claim 13 , in which the further reception opening is a further reception borehole.

15. The padlock in accordance with claim 13 , in which the two reception boreholes are arranged next to one another and mutually overlapping.

16. The padlock in accordance with claim 1 , in which the tumbler housing is substantially cylindrical and is aligned in parallel with the cylinder core.

17. The padlock in accordance with claim 16 , in which the tumbler housing has a cut-out arcuate in cross-section which extends in the axial direction and which the cylinder core contacts.

18. The padlock in accordance with claim 1 , further comprising a locking device for the selective locking and release of the hoop, the locking device comprising a rotational latch drive-effectively coupled to the cylinder core and two blocking balls which can be pressed into a respective locking recess of the hoop limbs of the hoop by means of the rotational latch.

19. The padlock in accordance with claim 1 , wherein the lock body is free of pin tumbler passages.

20. A padlock comprising:
a lock body;
a hoop, the hoop being displaceably held at the lock body;
a cylinder core into which at least one core pin is inserted and which is rotatably supported about a cylinder axis in direct contact with a reception opening of the lock body in order selectively to lock or release the hoop at the lock body; and
a tumbler housing that is received as a separate element from and in a fixed position relative to the lock body and into which at least one housing pin is inserted, the tumbler housing surrounding only a portion of a full periphery of the cylinder core.
