1. An electrically actuated mechanism for loading a door or other passage-closing structure in the closed position relative to a stationary member, comprising:

  • a lock bolt reciprocally mounted on one of said passage-closing structure or said stationary member and movable between a retracted, non-locking position and an extended, locking position;

    biasing means mounted on said one passage-closing structure or said stationary member for mechanically urging said lock bolt toward said retracted position;

    actuating means mounted on said one passage-closing structure or said stationary member and responsive to a momentary electrical signal for moving said lock bolt in opposition to said biasing means from said retracted position to said extended position;

    mechanical latch means mounted on the other of said passage-closing structure or said stationary member for retaining said lock bolt in said extended position notwithstanding cessation of said momentary electrical signal to said actuating means; and

    release means mounted on said one passage-closing structure or said stationary member and responsive to a momentary electrical signal for mechanically displacing said latch means and disengaging said latch means from said lock bolt to permit said biasing means to move said lock bolt from said extended position to said retracted position independently of any said electrical signals.
