Abstract

A lock device includes a first lock part, a second lock part, which can be arranged on the first lock part in a fastening direction and is connected to the first lock part in a closing state, and an actuating element, on which the second lock part is movably arranged. In the closing state the second lock part is held on the first lock part via the actuating element, and the second lock part acts with the actuating element such that in a loaded state, when force is acting on the second lock part relative to the first lock part along the fastening direction, the actuating element is rigidly connected to the first lock part and holds the second lock part on the first lock part, whereas in an unloaded state the second lock part can be detached from the first lock part by actuation of the actuating element.

First claim

The invention claimed is:

1. A lock device for releasably connecting two elements to each other, comprising:
a first lock part connectable to a first element,
a second lock part connectable to a second element, wherein the second lock part can be arranged on the first lock part in a fastening direction and is connected to the first lock part in a closing state of the lock device, and wherein, in a loaded state of the lock device, a force is acting on the second lock part relative to the first lock part along the fastening direction, and
an actuating element, on which the second lock part is movably arranged,
wherein in the closing state the second lock part is held on the first lock part via the actuating element and the second lock part acts together with the actuating element in such a way that in the loaded state, the actuating element is fixedly connected to the first lock part and holds the second lock part on the first lock part, whereas in an unloaded state the second lock part can be detached from the first lock part by actuation of the actuating element, and
wherein in the closing state the actuating element is held by friction or catch locking on the first lock part via a section provided between the first lock part and the second lock part, which is elastic at least in sections.

2. The lock device according to claim 1 , wherein the friction-locking or catch-locking connection between the actuating element and the first lock part is blocked in the loaded state of the second lock part, whereas in the unloaded state of the second lock part it can be released.

3. The lock device according to claim 1 , wherein the actuating element can in the fastening direction be inserted together with the second lock part into a recess of the first lock part to establish the closing state and, to release, can be taken out from the recess counter to the fastening direction.

4. The lock device according to claim 1 , wherein the second lock part is arranged shiftably along the fastening direction on the actuating element.

5. The lock device according to claim 4 , wherein the second lock part is mounted shiftably on the actuating element via at least one guiding opening.

6. The lock device according to claim 1 , wherein in the closing state in the loaded state the actuating element is held friction-locking by static friction on the first lock part.

7. The lock device according to claim 6 , wherein the second lock part has a blocking section with at least one run-up slope, which, when a force is acting on the second lock part relative to the first lock part along the fastening direction, runs up onto a run-up slope on a section of the actuating element, so that the blocking section connects the section of the actuating element to the first lock part by friction.

8. The lock device according to claim 7 , wherein the second lock part has a blocking section, which connects the second lock part and the actuating element to each other in such a way that, when a force is acting on the second lock part, the blocking section acts onto a section of the actuating element, so that the blocking section connects the section of the actuating element to the first lock part by friction.

9. The lock device according to claim 6 , wherein in the unloaded state the actuating element is held on the first lock part by static friction.

10. The lock device according to claim 1 , wherein the actuating element has at least one catch locking element, which in the closing state engages positive-locking with a catch section of the first lock part.

11. The lock device according to claim 10 , wherein the second lock part has a blocking section, which in the loaded state, when a force is acting on the second lock part, acts together with the at least one catch locking element of the actuating element to block the catch-locking connection of the actuating element to the first lock part.

12. The lock device according to claim 11 , wherein the blocking section has at least one run-up slope, which, when a force is acting on the second lock part, runs up onto a run-up slope of the at least one catch locking element in such a way that the at least one catch locking element cannot be detached from the catch section.

13. The lock device according to claim 11 , wherein the blocking section, when a force is acting on the second lock part, comes into engagement with a housing section of the at least one catch locking element in such a way that the at least one catch locking element cannot be detached from the catch section.

14. The lock device according to claim 11 , wherein the blocking section connects the second lock part and the actuating element to each other in such a way that when a force is acting on the second lock part the blocking section acts onto a section of the actuating element in such a way that the at least one catch locking element cannot be detached from the catch section.

15. The lock device according to claim 10 , wherein in the unloaded state the positive-locking connection between the at least one catch locking element of the actuating element and the catch section of the first lock part can be released by applying a compressive force onto the at least one catch locking element and removing the at least one catch locking element from the catch section.

16. The lock device according to claim 10 , wherein in the unloaded state the positive-locking connection between the at least one catch locking element of the actuating element and the catch section of the first lock part can be released by applying a tensile force onto the actuating element relative to the first lock part.

17. The lock device according to claim 16 , wherein the at least one catch locking element has a slope, which is designed in such a way that when a tensile force is acting onto the actuating element counter to the fastening direction, the slope runs up onto the catch section and thereby the positive-locking connection of catch locking element and catch section is released.

18. The lock device according to claim 10 , wherein in the unloaded state the positive-locking connection between the at least one catch locking element of the actuating element and the catch section of the first lock part can be released by turning the actuating element around the fastening direction or by shifting the actuating element relative to the first lock part transverse to the fastening direction.

19. The lock device according to claim 1 , further comprising restoring means to transfer the second lock part either into an unblocked position relative to the actuating element in the unloaded state or into a blocked position relative to the actuating element.

20. The lock device according to claim 19 , wherein the restoring means are formed mechanically by a spring or magnetically.
