Abstract

Provided is a closure device for the releasable connecting of two parts to each other including a first closure part, having a first base body, at least two first engaging sections formed on the first base body, spaced apart from each other along a loading direction and forming between them a gap, and at least one first magnetic section arranged on the first base body, and a second closure part, having a second base body, at least one second engaging section formed on the second base body, and at least one second magnetic section arranged on the second base body.

First claim

The invention claimed is:

1. A closure device for the releasable connecting of two parts to each other, with
a first closure part, having a first base body, at least two first engaging sections formed on the first base body, spaced apart from each other along a loading direction and forming between them a gap, and at least one first magnetic section arranged on the first base body, and
a second closure part, having a second base body, at least one second engaging section formed on the second base body, and at least one second magnetic section arranged on the second base body, wherein the first closure part and the second closure part are placeable against each other such that, in a closed position, the at least one second engaging section is received at least partly by the gap for the bracing of a loading acting between the first closure part and the second closure part along the loading direction, wherein in the closed position the at least one first magnetic section and the at least one second magnetic section interact by magnetic attraction,
wherein the first base body is connectible to a first part and the second base body to a second part, wherein at least one of
the first base body comprises a first fastening section, by which the first base body is to be connected to the first part, wherein the first fastening section defines a plane extending along the loading direction, relative to which a bottom of the gap is recessed, and
the second base body comprises a second fastening section, by which the second base body is to be connected to the second part, wherein the second fastening section defines a plane extending along the loading direction, relative to which a bottom adjoining the at least one second engaging section is recessed,

wherein the at least one second engaging section comprises a bearing surface, which in the closed position is in abutment with one of the at least two first engaging sections for the bracing of a loading acting in the loading direction on the second closure part, and
wherein the bearing surface is inclined to the loading direction and to a closing direction, along which the first closure part and the second closure part may be placed against each other, such that, under a loading against the second closure part in the loading direction, the bearing surface of the at least one second engaging section is configured to provide a force component in the closing direction relative to the first closure part to prevent the first and second closure parts from separating.

2. The closure device according to claim 1 , wherein the at least two first engaging sections of the first base body and/or the at least one second engaging section of the second base body are made of a flexible material.

3. The closure device according to claim 1 , wherein an intermediate section of the first base body between the at least two first engaging sections of the first base body is made of a flexible material.

4. The closure device according to claim 1 , wherein the flexible material comprises a thermoplastic elastomer, especially a thermoplastic polyurethane, or a synthetic rubber material, especially acrylonitrile-butadiene rubber.

5. The closure device according to claim 1 , wherein the flexible material comprises fibers, in particular glass fibers, especially in a fraction of less than 15 wt. percent.

6. The closure device according to claim 1 , wherein the at least two first engaging sections and/or the at least one second engaging section extend in the form of webs transversely to the loading direction.

7. The closure device according to claim 1 , wherein the at least one first magnetic section is formed by a magnetic element which is received in a receiving opening of the first base body, and/or in the at least one second magnetic section is formed by a magnet element which is received in a receiving opening of the second base body.

8. The closure device according to claim 1 , wherein a first magnetic section is arranged within each of the at least two first engaging sections and/or a second magnetic section is arranged within the at least one second engaging section.

9. The closure device according to claim 1 , wherein the at least one first magnetic section and/or the at least one second magnetic section are magnetized along a direction of magnetization which is collinear with the loading direction.

10. The closure device according to claim 1 , wherein at least one of the first base body and the second base body are curved, viewed along the loading direction.

11. The closure device according to claim 1 , wherein the first closure part comprises more than two first engaging sections, which are evenly spaced apart from each other along the loading direction, wherein every two adjacent ones of the first engaging sections form between them a gap, which is configured to at least partly receive the at least one second engaging section in the closed position.

12. An article of clothing, comprising a closure device according to claim 1 .
