Abstract

A padlock comprises a lock body and a hoop, in particular a flexible hoop, which has a first hoop end. In this respect, the lock body has a first hoop receiver in order to selectively receive the first hoop end therein. The lock body further comprises a blocking element which is displaceable between a blocked position in which it blocks the first hoop end against an exiting from the first hoop receiver and a release position in which it releases the first hoop end for an exiting from the first hoop receiver. The lock body furthermore comprises a drive element which is rotatable between a locked position in which it locks the blocking element in its blocked position and an unlatched position in which it permits a displacement of the blocking element into its release position. The drive element in turn comprises a rotary body and a latch element which is displaceably supported at the rotary body, with the latch element being preloaded toward the blocking element in the unlatched position in order to secure the blocking element against an automatic displacement into the release position.

First claim

The invention claimed is:

1. A padlock comprising a lock body and a hoop having a first hoop end, wherein the lock body has a first hoop receiver in order to selectively receive the first hoop end therein;
wherein the lock body comprises a blocking element which is displaceable between a blocked position in which it blocks the first hoop end against an exiting from the first hoop receiver and a release position in which it releases the first hoop end for an exiting from the first hoop receiver;
and wherein the lock body comprises a drive element which is rotatable between a locked position in which it locks the blocking element in its blocked position and an unlatched position in which it permits a displacement of the blocking element into its release position,
wherein the drive element comprises a rotary body and a latch element which is displaceably supported by the rotary body relative to the rotary body, and
wherein the latch element is preloaded toward the blocking element in the unlatched position in order to secure the blocking element against an automatic displacement into the release position.

2. The padlock in accordance with claim 1 , wherein the hoop is a flexible hoop.

3. The padlock in accordance with claim 1 , wherein the latch element is radially displaceable with respect to an axis of rotation of the drive element.

4. The padlock in accordance with claim 1 , wherein the rotary body has a latch receiver in which the latch element is received.

5. The padlock in accordance with claim 4 , wherein a spring element is further received in the latch receiver, said spring element preloading the latch element in the direction out of the latch receiver.

6. The padlock in accordance with claim 4 , wherein the latch receiver is aligned in the direction of the blocking element in the unlatched position.

7. The padlock in accordance with claim 4 , wherein a cross-section of the latch receiver and a cross-section of the latch element are formed in a complementary manner with respect to one another.

8. The padlock in accordance with claim 4 , wherein the latch receiver and the latch element are configured in such a manner that a rotational alignment of the latch element is fixed in the latch receiver.

9. The padlock in accordance with claim 1 , wherein the blocking element at least substantially has a spherical shape.

10. The padlock in accordance with claim 1 , wherein the latch element has a cylindrical basic shape;
wherein a transition from a jacket surface of the latch element is rounded off or chamfered toward an end face facing the blocking element in the unlatched position;
and wherein the transition is radially aligned in such a manner that it is led past the blocking element on the rotation of the drive element from the locked position into the unlatched position.

11. The padlock in accordance with claim 1 , wherein the rotary body has a cylindrical basic shape with a jacket surface which locks the blocking element in its blocked position in the locked position and which has a recess which is aligned toward the blocking element in the unlatched position and which permits a displacement of the blocking element into its release position.

12. The padlock in accordance with claim 11 , wherein the jacket surface is a concavely formed jacket surface.

13. The padlock in accordance with claim 11 , wherein the latch element extends into the recess while it secures the blocking element against an automatic displacement into the release position.

14. The padlock in accordance with claim 1 , wherein the lock body comprises a lock cylinder which is operatively coupled to the drive element in order to rotate the drive element between the locked position and the unlatched position in dependence on an actuation of the lock cylinder.

15. The padlock in accordance with claim 1 , wherein the lock body comprises a lock cylinder which is operatively coupled to the rotary body, in order to rotate the drive element between the locked position and the unlatched position in dependence on an actuation of the lock cylinder.

16. The padlock in accordance with claim 1 , wherein the hoop has a second hoop end which is permanently connected to the lock body.

17. The padlock in accordance with claim 10 , wherein the second hoop end is permanently received in a second hoop receiver of the lock body.

18. The padlock in accordance with claim 10 , wherein the lock body comprises a further blocking element which blocks the second hoop end against an exiting from the second hoop receiver in a blocked position;
and wherein the drive element locks the further blocking element in its blocked position both in the locked position and in the unlatched position.

19. The padlock in accordance with claim 1 , wherein the hoop has a second hoop end;
wherein the lock body has a second hoop receiver in order to selectively receive the second hoop end therein;
and wherein the lock body comprises a further blocking element which is displaceable between a blocked position in which it blocks the second hoop end against an exiting from the second hoop receiver and a release position in which it releases the second hoop end for an exiting from the second hoop receiver, with the drive element also locking the further blocking element in its blocked position in the locked position and also permitting a displacement of the further blocking element into its release position in the unlatched position.

20. The padlock in accordance with claim 19 , wherein the drive element comprises a further latch element which is displaceably supported at the rotary body; and
wherein the further latch element is preloaded toward the further blocking element in the unlatched position in order to secure the further blocking element against an automatic displacement into the release position.

21. A padlock comprising a lock body and a hoop having a first hoop end, wherein the lock body has a first hoop receiver in order to selectively receive the first hoop end therein;
wherein the lock body comprises a blocking element which is displaceable between a blocked position in which it blocks the first hoop end against an exiting from the first hoop receiver and a release position in which it releases the first hoop end for an exiting from the first hoop receiver;
and wherein the lock body comprises a drive element which is rotatable between a locked position in which it locks the blocking element in its blocked position and an unlatched position in which it permits a displacement of the blocking element into its release position,
wherein the drive element comprises a rotary body and a latch element which is displaceably supported at the rotary body relative to the rotary body, and
wherein the latch element is preloaded toward the blocking element in the unlatched position in order to secure the blocking element against an automatic displacement into the release position, wherein the latch element has a cylindrical basic shape whose cross-section is a circular segment such that the latch element has a radial flat side.

22. The padlock in accordance with claim 21 , wherein a transition from the radial flat side is rounded off or chamfered toward an end face of the latch element facing the blocking element in the unlatched position and is aligned in such a manner that it is led past the blocking element on the rotation of the drive element from the locked position into the unlatched position.

23. A padlock comprising a lock body
