A lock assembly for a door includes a lock body for mounting above a door lever of the door and including a locking bolt supported in a housing of the lock body for movement between a retracted position and an extended position. The locking bolt is held in the retracted position and spring biased toward the extended position and releasable from the retracted position to move to the extended position in response to actuation of a trigger operatively coupled with the lock body. The lock assembly further includes a door lever assembly adapted for mounting on the door lever in rotative fixed relationship with the door lever, and operatively coupled with the locking bolt so that rotation of the door lever assembly causes movement of the locking bolt from the extended position to the retracted position.

An overhead door interlock device provides an electrical signal indication of the locked or unlocked status of an overhead door, and interfaces with control circuitry of the door's opener to allow or disallow operation of the door based on the locked or unlocked status. In one embodiment, a lever is pivotably attached to the doors track, with the lever engaging with a switch mechanism to indicate the locked or unlocked status of the door. A spring mechanism automatically returns the lever to an unlocked position when the door's lock bar is retracted, with the lever mechanically inhibiting locking of the door until the lever is moved by a user.

A pull handle may include a chassis, a latch disposed at least partially in the chassis, a thumb turn, and a dogging fastener movably disposed on the thumb turn. The thumb turn may be rotatable between a locking position and an unlocking position, where the thumb turn is coupled to the latch such that when the thumb turn is in the locking position the latch is in an extended position and when the thumb turn is in the unlocking position the latch is in a retracted position. The dogging fastener may be configured to move between a dogging position and an undogging position, where in the dogging position the dogging fastener engages the chassis to inhibit rotation of the thumb turn.

A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

A door lock for a domestic electrical appliance comprises a movably arranged locking member, which is selectively adjustable into an unlocking position and a locking position and in the unlocking position permits the opening of a closed door of the domestic appliance and in the locking position is in blocking engagement with a blockable component, at least when the door is closed. The blocking engagement causes the closed door to be blocked against opening. The door lock further comprises an electrically controllable actuator for actuating the locking member, and an electrical door detection switch that switches depending on the closing of the door. The doer lock also comprises an electrical auxiliary switch device, which selectively opens or closes an electrical shunt path to the door detection switch depending on the position of the locking member.

A method for operating a lockset generally includes transmitting an unlock command to an electronic actuator in response to receiving an unlock signal. In response to receiving the unlock command, the electronic actuator performs a first operation, including moving a holdback from a release position to a hold position. In response to actuation of a manual actuator, a latchbolt is moved from an extended position to a retracted position. The holdback in the hold position retains the latchbolt in the retracted position.
