Abstract
A magneto-mechanical locking device for locking a door can be displaced in relation to a stationary frame. The locking device contains a locking element produced from a magnetizable material and disposed on the frame. The locking device further has a permanent magnet that is mounted on the door and can be twisted from a first release position, in which the locking element is subject to substantially no action of magnetic force, to a second locking position, in which the locking element is attracted by the action of magnetic force of the permanent magnet and locks the door.
Claims22
A magneto-mechanical locking device on a movable door disposed opposite a stationary frame comprising:
- a locking element disposed on the stationary frame and made from a magnetizable material;
- a permanent magnet accommodated on the door, said permanent magnet being rotatable from a first release position where substantially no magnetic force effect is exerted on said locking element, to a second latching position where said locking element is attracted by a magnetic force effect of said permanent magnet for locking the door;
- and
- said locking element having projections for engaging, in the second latching position, in associated receptacles of the door for producing an interlocking connection.
