Abstract

A closure device for releasably connecting two parts with each other includes a first closure member and a second closure member attachable to the first closure member and in a closed position is held on the first closure member. The second closure member has a rigid second locking protrusion, wherein the second locking protrusion can be brought into engagement with the first locking protrusion in an engagement direction and in the closed position engages the first locking protrusion in a positive locking manner. The first closure member includes a first magnetic member and the second closure member includes a second magnetic member, the first magnetic member and the second magnetic member being constituted to magnetically attract each other when the second closure member is attached to the first closure member for closing the closure device.

First claim

The invention claimed is:

1. A closure device for releasably connecting two parts with each other, comprising
a first closure member having a rigid first locking portion,
a second closure member which is attachable to the first closure member and in a closed position is held on the first closure member, the second closure member having a rigid second locking portion, wherein the second locking portion can be brought into engagement with the first locking portion in an engagement direction and in the closed position engages the first locking portion in a positive locking manner,
wherein the first closure member comprises a first magnetic member and the second closure member comprises a second magnetic member, the first magnetic member and the second magnetic member being constituted to magnetically attract each other when the second closure member is attached to the first closure member for closing the closure device,
wherein a force application element is pivotably attached to the second locking portion at a force application location, the force application element being constituted to introduce a force into the second closure member,
wherein the first closure member further comprises a base and a locking element rigidly attached to the base and carrying the first locking portion, wherein the second closure member further comprises a locking part carrying the second locking portion and having a front face which, in the closed position, faces the locking element of the first closure member, and
wherein, in the closed position, when viewed in a direction opposite the engagement direction, the force application location on the second closure member is located between the front face and a center of the first magnetic member of the first closure member.

2. The closure device according to claim 1 , wherein the force application element is a bracket pivotable about a pivot axis on the second closure member constituting the force application location.

3. The closure device according to claim 1 , wherein the force application element is a rope, chain or cable pivotable about a pivot point on the second closure member constituting the force application location.

4. The closure device according to claim 1 , wherein the force application element is adjustably attached to the second closure member.

5. The closure device according to claim 1 , wherein the locking element with the first locking portion arranged thereon and the base forms a U-shaped recess in which the locking part with the second locking portion arranged thereon engages in the closed position of the closure device.

6. The closure device according to claim 5 , wherein the first locking portion forms a first leg and the base forms a second leg of the U-shaped recess, the first leg and the second leg extending substantially parallel to each other.

7. The closure device according to claim 1 , wherein the first closure member comprises a blocking element, wherein the blocking element in the closed position faces a back face of the second closure member facing in a direction opposite to the engagement direction, the blocking element being constituted to prevent the second locking portion from moving out of its engagement with the first locking portion in the direction opposite the engagement direction when the closure device is in its closed position.

8. The closure device according to claim 7 , wherein the second closure member comprises a support element attached to the locking part and extending, in the direction opposite to the engagement direction, beyond the locking part, the support element being constituted to prevent an abutment of the back face with the blocking element prior to the second locking portion engaging the first locking portion.

9. The closure device according to claim 1 , wherein
the first locking portion, on a side which in the closed position faces away from the second locking portion, comprises a slanted face or
the second locking portion, on a side which in the closed position faces away from the first locking portion, comprises a slanted face configured to guide the second locking portion, when attaching the second closure member in a closing direction perpendicular to the engagement direction to the first closure member, past the first locking portion when closing the closure device.

10. The closure device according to claim 1 , wherein, for opening the closure device, the second closure member is
pivotable with its second locking portion about the first locking portion of the first closure member or
displaceable such that the second locking portion slides along the first locking portion to disengage the second locking portion from the first locking portion.

11. The closure device according to claim 1 , wherein the force application element constitutes a belt receptacle for fixing a belt to the second closure member.

12. The closure device according to claim 1 , wherein the first closure member carries a belt receptacle for fixing a belt to the first closure member.

13. The closure device according to claim 1 , wherein the force application element is a bracket comprising two ends via which the force application element is pivotably attached to at least one opening of the second locking portion, wherein an attachment of the force application element to the second locking portion is secured by a securing element arranged on the bracket and preventing the ends from being detached from the at least one opening.

14. The closure device according to claim 1 , wherein the magnetic members are arranged to generate an attractive force along the engagement direction or in a direction perpendicular to the engagement direction.

15. The closure device according to claim 1 , further comprising a magnetic field sensor for sensing, in the closed position, a magnetic field produced by the magnetic members.

16. A closure device for releasably connecting two parts with each other, comprising
a first closure member having a rigid first locking portion,
a second closure member which is attachable to the first closure member and in a closed position is held on the first closure member, the second closure member having a rigid second locking portion, wherein the second locking portion can be brought into engagement with the first locking portion in an engagement direction and in the closed position engages the first locking portion in a positive locking manner,
wherein the first closure member comprises a first magnetic member and the second closure member comprises a second magnetic member, the first magnetic member and the second magnetic member being constituted to magnetically attract each other when the second closure member is attached to the first closure member for closing the closure device,
wherein the first closure member comprises a base and a blocking element rigidly attached to the base, wherein the blocking element in the closed position faces a back face of the second closure member facing in a direction opposite to the engagement direction, the blocking element being constituted to prevent the second locking portion from moving out of its engagement with the first locking portion in the direction opposite the engagement direction when the closure device is in its closed position, and
wherein the first closure member comprises a locking element rigidly attached to the base and carrying the first locking portion, wherein the second closure member comprises a locking part carrying the second locking portion and having a front face opposite the back face, the front face, in the closed position, facing the locking element of the fi
