A lock assembly has an actuator that is moveable between first and second positions and a locking structure that is coupled to the actuator. The locking structure is positioned to engage a portion of a lock when the actuator is in the first position to prevent movement of the actuator to the second position. A latch assembly is preferably coupled to the actuator and includes a latch that is moveable between engaged and disengaged positions. Moving the actuator from the first position to the second position moves the latch to the engaged position, and moving the actuator from the first position to a third position moves the latch to a disengaged position.

An exit device assembly for use in association with a door having a top, a bottom and a generally vertical surface. The exit door assembly includes an exit device configured to be mounted on the surface of the door, the exit device including a manually movable member, a latch mechanism configured to be mounted adjacent one of the top and the bottom of the door, the latch mechanism including a latch movable between a locking position and a non-locking position, and a non-rigid device for causing movement of the latch in response to movement of the manually movable member.

A glass door construction set in a pre-existing frame includes glass door leaves made of two or more panes of glass, which define a top edge, a bottom edge, and two lateral edges. The top and bottom edges include a top and bottom rail, respectively, to enhance the structural integrity of the glass door leaves. The lateral edges, however, remain free of the typical perimeter framing required on current glass doors to meet the stringent impact standards. The glass door leaves each include handles on either side of the glass leaves that are interconnected to effectively create a structural equivalent of an I-beam. The handles provide the necessary structural rigidity along a vertical extent to meet impact standards.

Latch mechanisms adapted to prevent unauthorized displacement of a latch bolt from an extended, locked position to a retracted, unlocked position. The latch mechanisms prevent the failure of a latch bolt of one latch mechanism to return to an extended lock position from interfering with the ability of a latch bolt of an inter-related latch mechanism from being able to return to an extended, locked position. Further embodiments provide a mounting bracket mounted to a door to allow the associated latch mechanism to be indirectly secured to the door. Additionally, the mounting bracket may have a plurality of mounting orifices that allow the mounting bracket to be used with a wide range of latch mechanisms, as well as provide adjustable attachment of the latch mechanism to the mounting bracket.

A universal door lock-driving assembly is installed in an exterior space of a door panel. The door panel is furnished with at least one of an embedded lock cartridge, an embedded vertical-extending lock bar assembly and an exposed vertical-extending lock bar assembly. The universal door lock-driving assembly includes a base set, an action unit, a driving member and a slidable unit. The slidable unit can assemble a first assembling member and a second assembling member. The first assembling member can apply a penetration slot on the base set to generate interaction with the embedded lock cartridge or the embedded vertical-extending lock bar assembly. The second assembling member can interact with an exposed lock bar. Thus, the universal door lock-driving assembly can be used to unlock at least the lock cartridge and the lock bar assembly.

Provided is a door lock, including at least one latch portion, and a controlling portion for actuating the latch portion. The controlling portion includes a base having a configuration hole and a linkage assembly disposed on the base. The linkage assembly includes an actuating member movably disposed on the base, a driving member connected to the actuating member, a sliding member connected to the driving member, disposed on the base and having at least one opening, and a connecting member connected to the sliding member and the latch portion for enabling the sliding member to drive the connecting member and actuate the latch portion and exposing the configuration hole from the opening when the actuating member drives the driving member to actuate the sliding member. When the door lock is repaired, the screw thread can be set in the configuration hole from the opening without removing the linkage assembly.

A center slide assembly for a multi-point exit device. Upper and lower spool assemblies may be displaced from first positions to second positions along an inner region of a center slide. The displacement of the spool assemblies may displace upper and lower pull cables so as to retract latch mechanisms from extended positions to retracted positions. A first latching pin may be displaced, along with the displacement of the upper spool assembly, along an abutment surface of a tilting link so as to pivotally displace the tilting link from an unlocked position to a locked position. Displacement of the lower spool assembly may displace a second latching pin to a position wherein the second latching pin may be received and retained within a jog of the tilting link when the tilting link is in the locked position, which may thereby retain the associated latch mechanism in the retracted position.

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.

An example exit device includes a mounting assembly configured for mounting to a door, a pushbar movably mounted to the mounting assembly, a latchbolt mounted to the mounting assembly for movement between an extended position and a retracted position, and a rocker lever engaged between the pushbar and the latchbolt such that the pushbar is operable to move the latchbolt between the extended position and the retracted position. The exit device further includes impact dampener mounted to the exit device and configured to dampen impact between a first component of the exit device and a second component of the exit device during movement of the first component relative to the second component.

The displacement of the spool assemblies may displace upper and lower pull cables so as to retract latch mechanisms from extended positions to retracted positions. A first latching pin may be displaced, along with the displacement of the upper spool assembly, along an abutment surface of a tilting link so as to pivotally displace the tilting link from an unlocked position to a locked position. Displacement of the lower spool assembly may displace a second latching pm to a position wherein the second latching pin may be received and retained within a jog of the tilting link when the tilting link is in the locked position, which may thereby retain the associated latch mechanism in the retracted position.
