Title: Electric lock with automatic spring opening
Inventor: HENRI VINCENTI
IPC: E05C19/16
Filed: 1989-10-25
Abstract: Electrical locking device making it possible remotely to lock and unlock doors constituting emergency exits, characterised in that it opens automatically, under the effect of a return spring (R), when its electrical supply is cut. The bolt (P) is driven, on closure, by an endless screw (V), itself rotated by a D.C. electric motor (M), the nut (E) moved by the endless screw is not solidly attached to the bolt. The bolt (P) is held in the closed position by an annular electromagnet (A) which it passes through, whilst the travel switch (I1) which it actuates by arriving in the extreme closure position causes the nut moved by the endless screw to return into the rear position, thus allowing the automatic opening operation of the lock under the effect of the return spring when the supply of the electromagnet is cut.
