Abstract: A push pad exit device comprising a horizontal push bar actuator mechanically linked to a vertical door handle assembly for use on the interior side of entrance doors where a means of emergency egress is desired, is presented. The operating mechanisms of the push bar actuator and vertical door handle assembly are concealed presenting a smooth uncluttered appearance. The push pad exit device further including an improved roller latch bolt. The improved roller latch bolt allows for a roller to make contact with a ramp surface of a corresponding strike plate on a sweep side of the plate and allows for the roller support to make contact with the strike plate on a latch side of the plate.

Abstract: A knob-less horizontal-shift fire door lock includes a base including a longitudinal bar, an unlocked-state positioning member arranged in the longitudinal bar and having a positioning section; a latch pivoted to the base and having a free end elastically biased outside the base to engage a keeper on a door jamb; a push board pivoted in the base; and a handle bar slidably mounted on the longitudinal bar. The handle bar is biased by an elastic element to protrude outwards and moving a guide pin to slide in a guide groove of the positioning section. The handle bar is depressible toward the longitudinal bar to move the push board to drive the latch to retract into the base to achieve an unlocked state. The handle bar is further shiftable horizontally to cause the guide pin to slide into a horizontal groove of the positioning section for being secured in position.

Abstract: An exit device having a dogging mechanism assembly for providing a visual indication of the state or position of at least certain components of the exit device, such as, for example, a latch, drive rod, and/or a hook bracket. The dogging mechanism assembly includes a displaceable arm actuator mechanism that is coupled to the hook bracket, the hook bracket being adapted to lockingly engage the drive rod. The actuator arm mechanism is adapted to displace an indicator mechanism at least from a first indicator position to a second indicator position as the actuator arm mechanism is displaced to at least one of a first position and a second position. The indicator mechanism has one or more indicators that provide a visual indication of a state or position of a component of the exit device when the indicator mechanism is in at least one of a first and second indicator position.

Abstract: A retractor element includes a rigid slide connected between a latch bolt and a solenoid plunger for movement between a first position and a second position, the slide operably connected to plunger. A pivoting link defines a slot having an inner end portion extending transversely, the slot configured for pivoting the link when the slide moves between the first position and the second position of the slide. When the retracting mechanism is energized the plunger retracts causing movement of the slide to the second position of slide and the pin to enter the transverse end of the slot in the link. A bearing surface intersects the path of movement of the pin such that significantly less current is required for retaining the plunger in the retracted position than to retract the plunger for blocking the return of the latch bolt to the projected position.

Abstract: An operative member (688) for a door lock (2) includes a body (690) having two walls (692) and a connecting wall (694) extending between the walls (692). The body (690) defines a space (698) extending from an end face (696) through the other end face (696) of the body (690). The space (698) has an opening (700) spaced from the connecting wall (692). Two end caps (708) are mounted to the end faces (696) of the body (690) and received in the space (698). Each end cap (708) includes a hook (722) having an insertion groove (724). The insertion grooves (724) of the end caps (708) face the same direction. The insertion grooves (724) of the end caps (708) receive two pins (622, 624). When the operative member (688) is operated, the hooks (722) push the pins (622, 624) to retract a latch (38) to a retracted, unlatching position.

Abstract: An electronic push retraction exit device includes a support rail, a push rail and a latch mechanism having a latch bolt operably connected to the push rail and movable between latched and unlatched positions. A control circuit in the exit device drives a linear actuator to retract and hold the push rail and the latch bolt in the unlatched position. The linear actuator preferably includes a stepping motor and is connected to the push rail through a lost motion connection allowing the exit device to be mechanically operated without moving the linear actuator. The control circuit preferably includes an electrical adjustment for the retraction distance of the latch bolt and an adjustable relatch timer. The exit device may be operated by a remote switch attached to a control connection, which may be permanently closed to simulate a prior art electrically operated exit device for compatibility with third party control systems.
