Abstract

A holding device (10) for holding a component (12), the holding device (10) being convertible from a component holding mode into a component release mode by magnetic force. The holding device (10) for holding the component (12) has a movable detent element (14), the position of which is not influenced by the magnetic force. A method for releasing a snap-in connection between a holding device (10) and a component (12) is also provided, having the following steps: generating a magnetic field in the vicinity of the holding device (10); and applying a force that moves the holding device (10) and the component (12) apart from each other to release the snap-in connection.

First claim

The invention claimed is:

1. A holding device for holding a component, with the holding device being convertible from a component holding mode into a component release mode by magnetic force, the holding device comprising: a movable detent element configured to hold the component, a position of which is not influenced by the magnetic force, and a locking element which inhibits a movement of the detent element in the component holding mode in an inhibited position, and which releases the movement of the detent element in the component release mode in a release position.

2. The holding device according to claim 1 , wherein the locking element consists of ferromagnetic material at least in sections.

3. The holding device according to claim 1 , further comprising a spring element ( 18 ) which pretensions the locking element in a direction of the inhibited position.

4. The holding device according to claim 1 , further comprising a housing, and the locking element rests against the housing in the inhibited position.

5. The holding device according to claim 1 , wherein the detent element is elastically deformable at least in sections.

6. The holding device according to claim 1 , further comprising a housing in which the detent element is arranged with clearance in a direction which runs perpendicular to an approach direction with which the component is approached for holding.

7. The holding device according to claim 1 , further comprising a housing in which the detent element is arranged, and a damping element between the housing and the detent element.

8. The holding device according to claim 1 , wherein the holding device is switchable from the component holding mode to the component release mode without magnetic force and non-destructively when a force which exceeds a predetermined threshold value acts between the component and the detent element.

9. A method for releasing a snap-in connection between a holding device and a component, comprising the following steps:
generating a magnetic field in a vicinity of the holding device; and
applying a force that moves the holding device and the component apart from each other to release the snap-in connection;
wherein a magnetic force is exerted by the magnetic field, and said magnetic force moves a locking element from an inhibited position, in which the locking element inhibits a movement of a detent element, into a release position, in which the locking element releases the movement of the detent element.

10. The method according to claim 9 , wherein the locking element is converted from the inhibited position into the release position against a spring force.

11. The method according to claim 9 , wherein the detent element is elastically deformed when the connection is released, when the locking element is located in the release position and the force moving the holding device and the component apart from each other is applied.

12. The method according to claim 9 , wherein the magnetic field is generated by an electromagnet which is activated to release the connection.

13. The method according to claim 9 , wherein the holding device is part of a first aircraft component and the component is part of a second aircraft component.
