摘要： For use with a conventional retractable latch bolt, an electrically operated strike assembly comprising a strike lip movable between its closed position effective to block the latch bolt and its open position, solenoid means, a locking cam or locking member movable between a first position corresponding to the closed and locked condition of the lip and a second position corresponding to the unlocked condition of the lip, and cam means drivingly connected to the lip to be moved thereby when the lip moves from its closed condition to its open condition. The locking cam is effective to prevent movement of the said cam means by the lip when the locking cam is in its first position. The solenoid is operatively connected to the locking cam and arranged to move it from its first position to its second position.

摘要： A latch and actuator assembly, primarily intended for use as a panic exit device, in which a push bar substantially spanning the width of a hinged closure is mounted for bodily rectilinear movement in the closure-opening direction and perpendicularly toward the closure, one or more toggle-like linkages being interposed between the push bar and an actuator, mounted for movement transversely of the closure and operatively connected to a movable latch bolt, the actuator being biased toward boltprojected position and being moved to bolt-retracted position by the elongation of the toggle-like linkages upon such movement of the push bar. In one form of the invention, the apices of two such toggle-like linkages are joined by a rigid stretcher; while in another and preferred form, a guide lip engages the roller at the apex of each toggle to confine that roller in contact with the inner surface of the push bar.

摘要： A panic exit latch and actuator assembly comprising housing means, a latchbolt movable between a projected position and a retracted position, an actuator element operatively connected to the latchbolt and arranged to move the latchbolt to its retracted position in response to movement of the actuator element, and control means including a control member movable between a first position and a second position and cooperating means for locking the actuator element in its latch-projected position. The control member and the actuator element are connected to the latchbolt by lost-motion connection means so that the latchbolt can be retracted by the control member without changing the position of the actuator element and so that the latchbolt can be retracted by the actuator element without changing the position of the control member. The said cooperating means is operated by movement of the control member to lock the actuator element against movement which, in turn, locks the panic bar against movement.
