A lock assembly for a door includes a lock body having a housing with at least one deadbolt supported in the housing for movement between a retracted position and an extended position and biased toward the extended position by a spring, and a trigger mechanism mounted on the door separate from the lock body for engagement with a door jamb upon closure of the door, said trigger mechanism being adapted to hold the at least one deadbolt in the retracted position when the door is open in opposition to a spring bias, and to permit movement of the at least one deadbolt to the extended position upon engagement of the trigger mechanism with the door jamb.

In an embodiment, the present application discloses a door lock, comprising: a knob, positioned on a side of a door; a lock body, disposed within the door; and a connecting assembly, comprising a connecting shaft, comprising a front end and an opposite, rear end; and a receiving piece, comprising a connecting shaft receiving portion and a knob receiving portion. The knob receiving portion is configured to fixedly connect to the knob, and the connecting shaft receiving portion is configured to receive and detachably connect to the rear end. In an installed state, the front end acts on at least a part of the lock body to control the open and close of the lock body. The connecting shaft receiving portion and the rear end further have at least two connecting mechanisms in a longitudinal axis direction, so as to adjust the distance between the knob and the lock body. The door lock can adapt to doors of different thicknesses by adjusting the distance between the knob and the lock body.

A privacy lock assembly and method of operation are provided. The lock assembly has a push button offset from the central axis of the lock assembly for locking and unlocking the assembly. The lock assembly includes compression springs to maintain integrated handles in predetermined orientations when the handles are not subject to a load.

Various disclosed embodiments include a lock assembly and hinge assembly. The hinge assembly has a security engagement extension feature. The hinge assembly also includes a receiver. The receiver has a receiving area for receiving at least a portion of the security engagement extension feature and the receiver has a receiver security engagement feature formed as part of the receiver. The receiver security engagement feature is complementary to the security engagement extension.

A door having a modular locking system that in embodiments includes a dish which can be arranged on a first side of the door; an actuating lever that can be pivoted in relation to the dish for actuating the locking device that is on the other side of the door; a securing device for arresting the actuating lever on the dish; and a release module that disengages the arresting action; wherein the release module is an extension of the dish.

Various embodiments, relate to a system of lockers including a plurality of tracks and a plurality of walls. At least two of the plurality of walls slidably coupled to at least two of the plurality of tracks. Four of the plurality of walls form four sides of a locker cavity. The system also includes a plurality of doors. Each of the plurality of doors are oriented perpendicular to the plurality of the walls. A first door of the plurality of doors is coupleable to a second door of the plurality of doors so as to form a third door, and at least one of the plurality of doors form one side of the locker cavity. The system also includes a back wall, which forms one side of the locker cavity. The system further includes a lock for securing positions of the plurality of walls and of the plurality of doors.

A privacy lock assembly and method of operation are provided. The lock assembly has a push button offset from the central axis of the lock assembly for locking and unlocking the assembly. The lock assembly includes compression springs to maintain integrated handles in predetermined orientations when the handles are not subject to a load.

An interconnection assembly includes a chassis, and cam plates that are rotatably coupled to the chassis to pivot about a plurality of rotational axises. An upper cam plate is operatively coupled to a deadbolt. The upper cam plate has a cam surface. A lower cam plate is rotatably coupled to the chassis to pivot about a second rotational axis. The lower cam plate is operatively coupled to an interior latch bolt handle. The lower cam plate has a cam slot. A linkage bar is rotatably coupled to the chassis to pivot about a pivot axis. The linkage bar has a first linkage portion having a first cam follower configured to operatively engage the cam surface of the upper cam plate and has a second linkage portion having a second cam follower operatively received in the cam slot of the lower cam plate.

A lockable bolt device for an interior of a door. The lockable bolt device includes a door attachment plate having a horizontal aperture therethrough, configured to securely attach to the door, and a jamb attachment plate having two horizontal apertures therethrough, configured to securely attach to a door jamb. The jamb attachment plate also includes a vertical aperture therethrough, such that the vertical aperture is configured to removably accept an angled bolt therethrough for storage of the angled bolt when the lockable bolt device is in an unlocked configuration. When the door is in a closed position and the horizontal apertures are aligned, the two plates are configured to accept the angled bolt through the horizontal apertures to secure the door in the closed position. The lockable bolt device is useful to prevent an individual from passing through the door from an exterior of the door.

Apparatus, systems, and methods for selectively locking and unlocking a passenger door. The apparatus includes a first shaft, having a first longitudinal centerline, and a member, connected to the first shaft. A handle is connected to the first shaft via the member, the handle being movable via rotation of the first shaft from a locked position and an unlocked position. A first protrusion extends from the handle and a latch crank is connected to the second shaft. A second protrusion extends from the latch crank and a linkage is connected between the latch crank and the member. When the handle in the locked position, the first protrusion is positioned adjacent to the second protrusion to prevent rotation of the second shaft. When the handle is in the unlocked position, the first protrusion is positioned away from the second protrusion to enable the second shaft to rotate.
