The invention involves a keeper (20) to interact with a bolt (16) of a lock (10); The keeper includes a bracket (22) for attachment to a structure, and a keeper rod (24) secured to the bracket, the keeper rod extending from one surface (27) of the bracket. In the keeper, a shaft (32) is attached to the bracket and can rotate freely relative to the bracket such that it extends in a longitudinal direction (X); a blade (40) is mounted on the shaft (32) on one side of the bracket near the keeper rod in such a way as to always rotate along with the shaft; an angular position indicator (46) is also mounted so as to always rotate along with the shaft; the blade being so positioned that it can be rotated by the latch when the latch hooks on to or releases from the keeper rod, and the angular position indicator (46) being capable of indicating the angular position of the blade. The invention is for example intended to be used on an aircraft door such as that of a helicopter.

An actuator-controlled strike comprising a housing disposable within a doorframe and including a chamber for receiving a spring latch and a dead latch of a mortise-type lockset. A keeper is pivotably mounted within the chamber to restrain the spring latch. A pivotable spring latch lifter is positively driven by the keeper, and a pivotable dead latch release platform is supported by the keeper when the spring latch is locked within the strike. The keeper is released by the actuator and then may be rotated which causes rotation of the dead latch release platform, allowing the dead latch to enter the chamber. The keeper positively drives the spring latch lifter to lift the spring latch onto the external ramp of the strike. In an alternate embodiment, an internal ramp feature may be used instead of the spring latch lifter to positively lift the spring latch out of the chamber.

An actuator-controlled strike comprising a housing disposable within a doorframe and including a cavity for a spring latch and a dead latch of a mortise-type lockset. A keeper is pivotably mounted within the chamber to engage the spring latch. A pivotably mounted kicker cooperates with the keeper. A pivotably mounted dead latch release is supported by the keeper when the spring latch is within the strike. The keeper is released by the actuator and rotates into a position to ramp the spring latch out of the strike, also allowing the dead latch release to release the dead latch into the cavity, allowing the spring latch to be ramped out of the strike. Pivoting the keeper causes the kicker to urge the spring latch onto an exit ramp on a face of the keeper. The dead latch release can be installed in a plurality of different locations in the housing.

An actuator-controlled electric strike for operating in conjunction with a spring latch of a lockset is provided. The strike comprises a housing having an entry chamber therein, and a spring latch keeper disposed in the entry chamber for movement between a keeper locked position and a keeper unlocked position. The spring latch keeper includes a keeper face, a second surface recessed from the keeper face and a contact ridge between the keeper face and second surface. The keeper face is contactable by the spring latch when the spring latch keeper is in the keeper locked position. The contact ridge, disposed at a non-perpendicular angle with the rotational axis of the keeper is contactable by the spring latch as the keeper moves toward its unlocked position so that a contact point on said spring latch changes as said spring latch exits said entry chamber.

An electric strike assembly includes a housing formed with a recessed portion therein, a keeper assembly pivotably mounted in the recessed portion of the housing, a lock leg pivotably mounted in the recessed portion of the housing and configured to rotate independently of the rotation of the keeper assembly, a block assembly having a blocking element configured to engage and disengage the keeper assembly, and to control engagement and disengagement of the blocking element with the keeper assembly. A method of capturing and releasing a latch bolt mounted in a door includes mounting an electric strike assembly in an associated door jamb and controlling an actuator to rotate an, actuator paddle to engage a blocking element such that the blocking element is engaged or disengaged from a keeper assembly.

A lock including a latch provided at one of a door and a cabinet, and a coupler provided at the other one of the door and the cabinet, the coupler including a housing including a latch insertion hole, an engaging lever including an engaging lever body rotatably provided within the housing, a latch insertion groove having a first end of the latch inserted therein by extending from a first end of the engaging part body, and first, second, third, and fourth projections formed by extending a second end of the engaging lever body.

A surgical device comprising: a closure assembly including: (a) a movement unit including: a bar that moves in a direction of a prescribed motion; (b) a latch unit including: (i) a latch plate including a hook latch that selectively receives the bar, the latch plate being movable in the direction of the prescribed motion between (A) a lockable state where the hook latch is engageable by the bar of the movement unit, and (B) an unlockable state where the bar does not reach the hook latch or the hook latch is moved out of alignment with the prescribed motion so that the hook latch is not engaged by the bar; and (ii) a stop that restricts movement of the movement unit relative to the hook latch.

The present disclosure provides a door lock device for releasably locking a door of a washing machine. The door lock device has first to third latches, and a drive motor and a latch drive mechanism for moving the third latch. The first latch releasably locks the door of the washing machine and is movable in frontward and rearward directions. The movement of the first latch is changed at a change position. The first latch is always biased frontward by a spring. The second latch releasably locks the first latch, which locks the door of the washing machine, at a door locking position. The third latch is moved in a direction perpendicular to the movement direction of the first latch. The third latch restricts the first latch at the door locking position, or unlocks the first latch after pushing the first latch from the door locking position against the spring.
