Magnetic action lock
First Claim
1. Magnetic action lock, comprising a case, a cover and a frontal closure plate of the case inserted in the impost, a strike which can be opposed to the frontal plate when the impost of the door is brought adjacent to the jamb, a pair of magnets, a bolt inside whereof the first magnet of the pair is inserted, which in the closure position is inserted in the strike in which the second magnet of the pair is positioned, a mechanism for opening/closure of the lock and mechanisms for return of the handle, characterised in that the magnet in the bolt and the magnet in the strike have the poles aligned in the direction parallel to the axis of movement of the bolt, in that the frontal plate, the case and the cover are made in a ferromagnetic material and the strike is made in a non-magnetic material.

Abstract
Magnetic action lock for inside doors, comprising a case fixed in a cavity of the impost wing of the door and a frontal closure plate, a strike in the jamb of the door which can be opposed to said frontal plate, a bolt and a mechanism for movement of said bolt, a pair of magnets inserted in the head of said bolt and in said strike respectively, wherein the position of opening of said bolt is obtained thanks to the concatenation of magnetic flows between the magnet in said bolt and the frontal closure plate, while the position of closure is achieved thanks to the attraction of the magnet in said bolt by the magnet in said strike, wherein the magnets have the poles oriented parallel to the axis of motion of said bolt, the case and the frontal closure plate are in ferromagnetic material and the strike is in a non-magnetic material.
