Abstract (en)
A latch bolt assembly having a blocking member (60A,60B) which is held in a non-blocking position by a fusible element (62A,62B) and which is biased into a blocking position upon a melting of the fusible element. In one embodiment of the invention, the blocking member (60A) is pivotable into a position to engage a portion of a handle mechanism (22) of the latch bolt assembly to prevent operation of the handle. In a second embodiment of the invention, the blocking member (60A) is slidably carried in the latch bolt (14) and is slidable into a position preventing retraction of the latch bolt upon a melting of the fusible element. <IMAGE> <IMAGE>
