ABSTRACT:
A flush bolt mechanism includes a frame, a slide guide bracket, a plunger reciprocally retained in the slide guide bracket having two first slots, a trigger member mounted to the plunger and reciprocally movable between a retracted position and an extended position, an elongated linkage assembly extending through the frame, and a resilient member biasing the linkage assembly toward a downward direction. The linkage assembly having a first end coupled to the shaft. The plunger includes two second slots and a shaft movable in the slots. The first and second slots are offset at an angle such that when the trigger member is activated to the retracted position, a second end of the linkage assembly is carried upwardly for latching engagement in the associated strike; when the trigger member is released from the retracted position, the second end of the linkage assembly is carried downwardly for disengagement with the strike.
