An anti-theft door lock assembly includes a main locking unit. The main locking unit has a main lock set, a lock tongue disposed inside the main lock set and having one end thereof to protrude out of the main lock set, a pushed member disposed inside the main lock set and connected with another end of the lock tongue, a connection link disposed inside the main lock set and connected with the pushed member, an action member disposed at one end of the main lock set, and a depression rocker arm furnished to the main lock set and connected with the connection link.

An exit device has an overall height when a panic bar of the exit device is in its extended position. The exit device is configured to be received, at least in part, within a recess defined within a body of the door so that the height at which the extended panic bar protrudes beyond an outer surface of the door is reduced.

A door exit device may include an actuator, an upper latch, and a lower latch. The actuator may be operatively coupled to the upper latch by a first drive and to the lower latch by a second drive. Each drive may include a housing which is mountable to the exterior of a door panel and a drive rod slidably supported within the housing. The housing may include a base which is mountable to the door panel and a cover attachable to the base with the drive rod located between the base and the cover. The housing may be configured to extend from the actuator to the latch to conceal the entire length of the rod between the actuator and the latch.

A latch mechanism having an adjustment mechanism that adjusts the distance to which a latch bolt extends into a mating recess. The adjustment mechanism may include a driver component and a driven component. Rotation of the driver component about a first axis may displace the driven component, thereby causing the position of the latch bolt to be adjusted along a second axis that is non-parallel to the first axis. According to certain embodiments, the first axis is perpendicular to the second axis. The latch mechanism may also include an inner housing that is displaced as the latch bolt is extended into, and retracted from, a mating recess in an adjacent structure. Further, the position of the inner housing may remain generally static as the position of the latch bolt is adjusted along the second axis via operation of the adjustment mechanism.

A dampener for an exit device may be disposed between a portion of an exit device actuator and an exit device chassis so that the dampener dampens vibrations to reduce noise of the exit device and/or inhibit unintentional movement of the actuator to an actuated position. The dampener may be composed at least partially of a viscoelastic material.

A reinforcing assembly may be configured for use in conjunction with a door latch mechanism. The reinforcing assembly is configured to reside within a recess or mortise defined within a body of the door. A body of said door latch mechanism is configured to be received, at least in part, within said reinforcing assembly. The reinforcing assembly includes a body having a back plate and one or more walls thereby defining a latch receiving cavity. At least one fastener is configured to secure the reinforcing assembly to the body of the door. The at least one fastener may be oriented substantially normal to the transverse plane of the door when securing the reinforcing assembly within the body of the door.

A latching device may include a latch, and a blocker configured to reduce the operational force used to move the latch to a latch disengaged position when an associated door is loaded with a force in a direction of egress. In some embodiments, the blocker may resist the force in the direction of egress by transferring the load the latch in a manner which reduces resultant friction generated by the latch when it is moved to the latch disengaged position. In some embodiments, the blocker may resist the force in the direction of egress by direction the force away from the latch.

A cable operated mechanical locking external disconnect enclosure for multi-point latch uses. The enclosures provide safety, in that, once the main enclosure door is closed, and the disconnect is turned on, the main enclosure is locked and only automatically unlocks when the disconnect is turned off. Thus, the door of the disconnect enclosure is locked when the disconnect or circuit breakers are turned to the on position. There is also a manual by-pass latch for each door.

A panic bar latch release assembly is disclosed having an inside latch release and an outside pull type handle latch. The handle latch includes a main housing having a pivotal pull handle. The inside latch release includes a first bar mount, a second bar mount, and an elongated push bar. The first bar mount has a support bracket with a floor with a first stop wall and an extended portion with a push rod guide hole extending therethrough. A body portion is coupled to the support bracket which includes a handle mount channel which is partially defined by a second stop wall. A handle mount is pivotally coupled to the body portion. An elongated push rod is positioned within a push rod channel of the door so as to extend through the push rod guide hole.

An exit device comprises an inner door handle adapted to be mounted to a door for movement relative to the door from a first position to a second position. A pair of brackets are adapted to be operatively connected between the respective ends of a horizontal portion and a vertical portion of the door handle. Each bracket comprises a first bracket member secured to the door handle, a second bracket member adapted to be secured to the door, and a pin for joining the first bracket member and the second bracket member for rotation about an axis through the pin. The first bracket member and the second bracket member pivot relative to one another when the door handle moves between the first position and the second position.
