In one form, a multipoint locking assembly included a first latch device, a second latch device, and a mortise assembly coupled to the first and second latch devices. The mortise assembly may comprise a first transmission coupled to the first latch device via a first flexible member, a second transmission coupled to the second latch device via a second flexible member, and an actuation assembly operable to actuate the first and second transmissions. At least one of the transmissions comprises a slack removal device operable to remove slack in the flexible member to which it is coupled, thereby ensuring proper transmission of pulling forces between the transmission and the latch device.

Mortise and multipoint latching assembly

An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.

Exit device systems and methods

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.

Multi-point exit device

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.

Adjustable dead-latching bolt mechanisms

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 door lock includes a latch assembly positioned at least partially within the door and movable between an engaged position in which the door is held in a closed position and a disengaged position in which the door is movable from a closed position to an open position. An outside spindle is rotatable about an axis and an inside spindle is rotatable about the axis to move the latch assembly between the engaged position and the disengaged position. A locking plate is movable along the axis between a locked position in which the outside spindle is fixed and an unlocked position in which the outside spindle and the inside spindle are each rotatable and a privacy lock actuator positioned on the inside of the door and movable in a direction substantially normal to the axis to move the locking plate between the locked position and the unlocked position.

In one form, a multipoint locking assembly includes a first latch device, a second latch device, and a mortise assembly coupled to the first and second latch devices. The mortise assembly may comprise a first transmission coupled to the first latch device via a first flexible member, a second transmission coupled to the second latch device via a second flexible member, and an actuation assembly operable to actuate the first and second transmissions. At least one of the transmissions comprises a slack removal device operable to remove slack in the flexible member to which it is coupled, thereby ensuring proper transmission of pulling forces between the transmission and the latch device.

An exemplary locking system includes an outer actuator, an outer spindle coupled to the outer actuator, a center spindle coupled to a latch assembly, and a lock control assembly selectively coupling the outer spindle and the center spindle. The lock control assembly is operable in a locked state wherein rotation of the manual actuator is prevented, and an unlocked state wherein the manual actuator is operable to rotate the center spindle. The lock control assembly is configured to transition from the locked state to the unlocked state in response to rotation of the center spindle, for example by an inner actuator.
