Abstract
A body (14) of the electric lock, embedded in a jamb of a fixed frame, contains an electromechanical release device comprising a loading bolt (28) suitable to be retracted in the body (14). A pusher (34) is movable between a retracted position in the body (14) and a forward position in a selvage (26) to expel from the selvage (26) the nose (20) of the lock and release the latter. There are provided elastic means (52) for the pusher (34) to be returned to the forward position. An escapement system (44) is suitable to hold the pusher (34) at the retracted position. A kinematic mechanism (46) interlocks the loading bolt (28) and the escapement system (44) such that, when the loading bolt (28) is caused to retract, the pusher (34) is held at the retracted position by the escapement system (44); when an electromagnet (42) is excited, the escapement system (44) releases the pusher (34), which is snapped to the forward position to expel the nose (20).
