<p>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 ).</p> |
