Abstract

A to a padlock comprising a lock body and a hoop that is movable between a closed position and an open position and that has a first hoop end and a second hoop end, wherein a first hoop receiver for the first hoop end and a second hoop receiver for the second hoop end are formed in the lock body, and wherein a latch mechanism is provided that is adjustable by a cylinder core that is rotatable about a cylinder axis between a locked position in which the latch mechanism fixes the hoop in the closed position and a release position in which the latch mechanism releases the hoop for a movement into the open position.

First claim

The invention claimed is:

1. A padlock having a lock body and a hoop, the hoop being movable between a closed position and an open position and the hoop having a first hoop end and a second hoop end, wherein a first hoop receiver for the first hoop end and a second hoop receiver for the second hoop end are formed in the lock body,
wherein a latch mechanism is provided that is adjustable by means of a cylinder core rotatable about a cylinder axis between a locked position in which the latch mechanism fixes the hoop in the closed position and a release position in which the latch mechanism releases the hoop for a movement into the open position,
wherein the hoop is formed as one of a rigid hoop and a flexible hoop,
with both a first retaining pin passage for a rigid hoop and a second retaining pin passage for a flexible hoop being formed in the lock body, with the first retaining pin passage opening into the first hoop receiver and the second retaining pin passage opening into the second hoop receiver;
and with a retaining pin being provided that is inserted into the first retaining pin passage with a rigid hoop and is inserted into the second retaining pin passage with a flexible hoop, with the retaining pin, in the open position of the hoop, plunging into the first retaining pin passage and securing the first hoop end against a removal from the first hoop receiver with a rigid hoop, and plunging into the second retaining pin passage and securing the second hoop end against a removal from the second hoop receiver with a flexible hoop.

2. The padlock in accordance with claim 1 ,
wherein the two retaining pin passages have the same cross-section.

3. The padlock in accordance with claim 2 ,
wherein the two retaining pin passages have the same diameter.

4. The padlock in accordance with claim 1 ,
wherein the second retaining pin passage is arranged above the first retaining pin passage and/or beneath the latch mechanism.

5. The padlock in accordance with claim 1 ,
wherein a plurality of tumblers arranged above one another are provided, with the second retaining pin passage being arranged above the plurality of tumblers and/or the first retaining pin passage being arranged next to and/or beneath the uppermost of the plurality of tumblers.

6. The padlock in accordance with claim 1 ,
wherein with a rigid hoop, the first hoop end has a longitudinal groove into which the retaining pin engages to displaceably secure the first hoop end in the first hoop receiver.

7. The padlock in accordance with claim 1 ,
wherein with a rigid hoop, no further retaining pin is inserted into the second retaining pin passage.

8. The padlock in accordance with claim 1 ,
wherein with a flexible hoop, the second hoop end has a cutout into which the retaining pin engages to fixedly secure the second hoop end in the second hoop receiver.

9. The padlock in accordance with claim 1 ,
wherein a compression spring is received in the first hoop receiver that urges the first hoop end in the direction of the open position of the hoop.

10. The padlock in accordance with claim 9 ,
wherein with a flexible hoop, an extension piece is received in the first hoop receiver.

11. The padlock in accordance with claim 10 ,
wherein the extension piece has a longitudinal groove and a further retaining pin is inserted into the first retaining pin passage that engages into the longitudinal groove of the extension piece to displaceably secure the extension piece in the first hoop receiver.

12. The padlock in accordance with claim 1 ,
wherein the cylinder core cooperates via an end face entrainer device with the latch mechanism.

13. The padlock in accordance with claim 1 ,
wherein the latch mechanism comprises two latches preloaded in opposite directions and respectively radially outwardly into the locked position in which the latches in the closed position of the hoop engage into respective locking sections formed in the first and second hoop ends to fix the hoop in the closed position.

14. The padlock in accordance with claim 13 ,
wherein the latches have a respective chamfer at their radially outwardly directed latch ends.

15. The padlock in accordance with claim 13 ,
wherein the locking sections are each formed as a groove at least partially peripheral around the longitudinal axis of the respective hoop end, with the latches having a respective concave cutout at their radially outwardly directed latch ends, said cutout being respectively counter-shaped to a part of the respective groove facing the respective latch end.

16. The padlock in accordance with claim 1 ,
wherein the cylinder core is directly received in a cylinder core receiver formed in the lock body.

17. The padlock in accordance with claim 1 ,
wherein housing pins and pin springs are directly received in housing pin bores that are formed in the lock body.

18. The padlock in accordance with claim 1 ,
wherein a plastic jacket is pushed onto the lock body from the hoop side and a plastic flap at the counter-hoop side is clipped onto it to form an outer housing for the lock body.

19. The padlock in accordance with claim 1 ,
wherein both a rigid hoop and a flexible hoop are provided that are selectively mountable to the lock body.
