ABSTRACT:
A latch device, which is especially adapted for an exit bar, incorporates a trigger assembly. When the latch device is retracted and released, as ordinarily occurs when the door is opened, the latch bolt is biased to an intermediate extended position. The trigger engages the rim of the strike plate which in turn releases a retainer arm and allows the latch bolt to project to an extended position within the strike thereby providing a latch function of high integrity.
