Patent ID: 8430434

Claim:
A mechanical-magnetic connecting structure for connecting two elements, comprising: a first connecting module connected to one of the two elements and comprising a spring locking element of a locking device, a second connecting module connected to the other of the two elements and comprising a locking piece of the locking device, the locking device constructed for formfittingly locking the connecting modules, a magnet-armature structure comprising a magnet arranged in one of the first and second connecting modules, and an armature arranged in the other one of the first and second connecting modules, wherein the magnet and the armature are movable relative to one another, and a coupling device coupling the magnet or the armature to the movable locking piece, wherein during a closing operation, the first and second connecting modules are moved towards each other, by means of the magnet-armature structure, are pulled towards each other starting from a predetermined minimum separation such that the spring locking element is urged against the locking piece until the spring locking element engages the locking piece in an engagement position in a formfitting manner such that the first and second connecting modules, by means of the locking piece and the spring locking element, are held with respect to each other, and during an opening operation, the magnet and the armature are moved relative to one another sideways with respect to the closing direction such that a magnetic force generated by the magnet-armature structure is weakened, wherein during the movement of the magnet and the armature relative to one another sideways with respect to the closing direction from the engagement position, in which the spring locking elements are moved relative to one another sideways with respect to the closing direction from the engagement position, in which the spring locking element is in engagement with the locking piece, into a non-engagement position, in which the spring locking element is no longer in engagement with the locking piece, thereby, allowing for a separation of the first and second connecting modules.
