An electronic door lock system includes a gasket system for protecting electrical and mechanical components from exterior water and air. A lock portion may include a gasket, a circuit board, and a plate disposed between a first and second housing. The gasket includes an L-shaped perimeter that wraps around a first side and perimeter edge of the circuit board. The plate compresses the gasket perimeter against a ridge on the first housing to form a seal around the circuit board.

Described herein are example fluid guards that can be used with locking devices. Various aspects may be particularly applicable to electrical locks, but they may also be applicable to mechanical locks. A locking device guard can include a guard cover, a fluid absorber, and a coupling element. The fluid absorber can be configured in a closed configuration to fit at least partially within a cup of a lock face. The coupling element can be configured to couple the guard cover to the lock and can define a second axis. The coupling element can be configured to allow the guard cover to rotate about the second axis.

An anti-theft structure composed of a lock core composed of a lock core seat, a lock core shell, a push plate provided in a slide groove of the lock core shell, lock plates and washers alternately superimposedly provided in the lock core shell, a limiting plate and a positioning plate disposed on the lock core shell and placed in the lock core seat together with the shell, a latch lever, a brake bolt plate provided in an accommodating groove of the lock core seat, a compression spring provided in a groove of the lock core seat and pushing against the brake bolt plate, a positioning baffle provided in an accommodating chamber of the lock core seat and located at a bottom of the lock core shell, and a retaining ring embedded in a ring groove of the lock core seat; and a key provided with a ring groove.

A latch assembly for use in a storage container is provided, and comprises a bracket having a body, a first side, and a second side, the bracket being releasably secured to the first or the second body component of the storage container. The first side includes a protruding segment. The body includes at least one slot positioned thereon, the bracket being secured to the storage container via a fastener inserted through the at least one slot. The latch assembly also includes a handle secured to the bracket. When the handle is moved in a first direction, the bracket moves from a latched position to an unlatched position where the protruding segment passes through a lock box assembly, and when the handle is moved in a second direction, the bracket moves from an unlatched position to a latched position where the lock box assembly blocks movement of the protruding segment. The latch assembly is used in conjunction with a lock system.

A door lock system includes a toolless handing assembly that selectively sets a handle in a left or right home position. The handing assembly may cooperate with a disc and a spring that biases the disc to a default position. The disc may be rotated in a first direction to set the disc in a first home position. A catch may engage the disc to retain the disc in the first home position. The catch may be released to return the disc to the default position and the disc may be rotated in a second direction to set the disc in a second home position, opposite the first home position.

A lock portion of an electronic door lock system includes a first housing and a second housing secured to a backplate of the first housing. The second housing is secured to a first surface of the backplate and only accessible from a second surface of the backplate. One or more wires are secured to the second housing in a service loop and connected to an actuator within the second housing.

A door lock system may include an outer spindle operatively connected to a disc with a larger diameter than a diameter of the outer spindle. The disc may include an opening that slidingly receives a lock spindle along a lock axis configured to engage a lock body. The lock spindle and the spindle opening may have complementary shapes and sizes such that the lock spindle is rotationally coupled to the disc about the center axis. Torque may be transmitted from a handle to the disc and from the disc to the lock spindle via the opening.

A door lock system that adjusts to doors of different thicknesses. The door lock system may include self-adjusting spindles that engage and center a lock body in a door. The spindles may exert equal and opposing forces that center the lock body within the door and align the lock body with a latch.

A door assembly includes a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces, a cylinder lock mounted to the second surface at the hole, and a cylinder dry lock assembly mounted to the door at the hole adjacent the first surface. The cylinder dry lock assembly including a main body that defines a central orifice, a low-friction member received within the central orifice, and an actuation mechanism extending from the low-friction member and engageable with the cylinder lock. Actuating the cylinder lock rotates the actuation mechanism, and the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces at the hole.

A lock for an aircraft door. The lock includes an outer shell having an inner cavity. A core is rotatably mounted within the inner cavity to rotate about an axis of the core. The core has a keyhole extending through the core from a first end of the core for receiving a key therein, to an opposed second end of the core. The keyhole defines an air leakage path through the core. A cam has a cam arm mounted about the core and is rotatable therewith. The second end of the core protrudes from the cam. A cover is attached to the second end of the core. The cover blocks the keyhole at the second end of the core and obstructing the air leakage path. An aircraft door, methods, and a retrofit kit are also disclosed.
