Patent ID: 8851534

Claim:
A magnetic closure with a magnet-armature structure, comprising: a first closure member having a magnet; a second closure member having an armature, the magnet and the armature being constituted such that, for an automatic closing, the armature and the magnet mutually attract each other in a closing direction below a predetermined minimum distance, wherein for opening the magnetic closure the magnet is moved with respect to the armature into an open position so that the surfaces of the magnet and the armature facing each other in a mutually attracting manner become smaller, whereby the force of attraction between magnet and armature becomes smaller; and an opening-assisting spring for assisting the opening, the opening-assisting spring being arranged on one of the first and the second closure member, wherein the opening-assisting spring is pretensioned during an opening operation, wherein the opening-assisting spring comprises an ejector pin attached thereto and is constituted such that a movement of the magnet with respect to the armature causes said ejector pin to be moved relative to a surface of the other of the first and the second closure member, thereby pretensioning the opening-assisting spring, and wherein the ejector pin, during the opening operation, is in contact with the surface of the other of the first and second closure member.
