Abstract: A door handle has an elongated member pivotally connected with a plate member. The elongated member has a toe portion which interacts with the plate member. In this way, the elongated member is at least partially retained by the plate member at each end. The door handle provides an anti-ligature design that thwarts suicide attempts by persons attempting to affix or hang ligatures on the door handle. The door handle is also easily operable by those with disabilities.

Abstract: A lock assembly for automatically dead bolting a closure to a closure frame when the ambient temperature is raised above a predetermined temperature by fire comprises a striker plate, which defines a bolt hole, mounted on the closure frame. A cooperating latching mechanism, installed in the closure, includes a housing and a bolt assembly mounted in housing for reciprocal movement to and from a latched position projecting into the striker plate bolt hole and for movement to an extreme dead bolted position projecting further into the bolt hole beyond the latched position. A stop pin mechanism associated with the bolt assembly prevents the bolt assembly from being moved out of the dead bolted position once this position is assumed and a spring urges the bolt toward the dead bolted position.
