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.

The invention provides a digital lock (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the digital lock (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close the digital lock (100, 1001, 1002).

A rotation converter according to certain embodiments generally includes a case, an input member, a shuttle, and an output member. The input member is rotatably mounted to the case, and is rotatable from an input member home position in each of a first rotational direction and a second rotational direction. The shuttle is movably mounted in the case, and is engaged with the input member such that rotation of the input member from the input member home position in each of the first rotational direction and the second rotational direction drives the shuttle from a shuttle home position to a shuttle actuated position. The output member is rotatably mounted to the case and engaged with the shuttle such that the output member rotates in an output member rotational direction in response to movement of the shuttle from the shuttle home position to the shuttle actuated position.

A door lock device is provided and includes: a housing, an acting assembly arranged in the housing and having a lock tongue, an operating assembly arranged in the housing and interlocked with an outdoor handle, and a regulating assembly arranged in the housing for a user to regulate the operating assembly into an interlocking state or an idle state. As such, in the interlocking state, the outdoor handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and in the idle state, the operating assembly cannot drive the acting assembly and the outdoor handle cannot be interlocked with the lock tongue.

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 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 lock with a handle assembly and a lock articulating assembly. The handle assembly has a handle member and a lock assembly. The handle member has a central bore and a locking plug groove. The lock assembly has a lock arm with a body positionable within the central bore. The body includes a central bore and a radial bore which is alignable with the locking plug groove. The lock assembly further has an outward locking plug configured to translate along the radial bore and selectively into the locking plug groove. The lock articulating assembly includes a slider (or a second cam), an actuator, a cam coupled to a motor. The cam is selectively engageable with the slider to rotate and/or translate the slider. The actuator is coupled to the slider, so that movement to the slider imparts movement of the actuator.

The invention provides a magnetic actuator (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the magnetic actuator (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close a digital lock realised with the magnetic actuator 100, 1001, 1002. The magnetic actuator of the invention can also be used to realise a valve.

A door lock device is provided and includes: a housing, an acting assembly arranged in the housing and having a lock tongue, an operating assembly arranged in the housing and interlocked with an outdoor handle, and a regulating assembly arranged in the housing for a user to regulate the operating assembly into an interlocking state or an idle state. As such, in the interlocking state, the outdoor handle drives the acting assembly through the operating assembly to cause the lock tongue to extend or retract relative to the housing, and in the idle state, the operating assembly cannot drive the acting assembly and the outdoor handle cannot be interlocked with the lock tongue.
