Abstract:
1. A mechanical-magnetic connecting structure for connecting two elements, to which one connecting module each can be attached, wherein the connecting modules comprise a locking device comprising: at least one spring locking element, which is arranged in one of the connecting modules, and a blocking piece for positively locking the connecting modules, which is arranged in the other connecting module, and a movable unlocking element with a force-deflecting rising sliding surface, which likewise is arranged in the other connecting module, and a magnet-armature structure comprising at least one magnet which is arranged in one of the connecting modules and at least one armature which is arranged in the other connecting module, wherein the locking device is operatively connected in that: a. the connecting module with magnet and the connecting module with armature can be shifted laterally with respect to each other and are formed such that a weakening of the magnetic force occurs the further the magnet and the armature are shifted against each other, b. the connecting module with magnet or the connecting module with armature is coupled with the unlocking element via a coupling device, so that in the case of the lateral displacement between magnet and armature the spring locking element is moved by the unlocking element from an engagement position in which the spring locking element is in engagement with the blocking piece into a non-engagement position in which the spring locking element no longer is in engagement with the blocking piece, wherein the force-deflecting rising sliding surface urges aside the spring locking element, c. the magnetic force is designed such that during a closing operation the connecting modules are pulled towards each other from a predetermined minimum distance, whereby the spring locking element is urged against the blocking piece, until the spring locking element snaps in engagement, and during a opening operation after reaching the non-engagement position between blocking piece and spring locking element the magnetic force is sufficiently weakened in order to separate the modules, and d. a return arrangement is provided for at least returning the unlocking element into the starting position in which the spring locking element can be brought in engagement with the blocking piece.
