A locking system for a door, including a primary locking mechanism and a secondary locking mechanism, in which the primary locking mechanism includes an electrical actuator that causes a first plate and a second plate to be magnetically attracted to one another when actuated such that rotation of a doorknob effects a corresponding rotation of the spindle, and in which the secondary locking mechanism includes a detent that is formed in a knob collar and an aperture that extends through a rotator collar; and a pin that is translatable through the aperture to be disposed in the detent of the knob collar, when the secondary locking mechanism is in an unlocked condition, such that the knob collar and the rotator collar are rotatably fixed to one another.

A door handle includes a human body detection sensor, a controller, a servo assembly, and an engaging assembly. The controller is electrically connected with the human body detection sensor and the servo assembly, and the engaging assembly is controlled by the servo assembly. The engaging assembly includes a first engaging state and a second engaging state. When the engaging assembly is in the first engaging state, the door handle is able to drive a lock body connecting shaft to rotate; and when the engaging assembly is in the second engaging state, the door handle is unable to drive the lock body connecting shaft to rotate.

A door handle is configured for mounting to a door, and includes a shell having a front side and a rear side, with the shell defining an internal chamber. A shank extends from the rear side of the shell, and a light source is seated in the internal chamber. A window pattern is positioned on the rear side of the shell such that the light source is operable to project onto the door a light pattern corresponding to the window pattern.

A child/pet-proofing apparatus and system is described. The apparatus is configured to facilitate the locking and unlocking of doors, cabinets, and drawers of a household while retaining the original aesthetic of the doors, cabinets, and drawers by employing the pre-existing hardware as a sophisticated manipulator of an internal locking mechanism disposed within a housing behind the face or front of the drawer or cabinet. The locking mechanism is configured to be locked and unlocked via two-step process which namely includes pushing the knob inwards and then turning the knob while it remains depressed. As the push-and-turn action is performed, an internal pocket spring is compressed, which enables the placement of locking pins into specifically arranged pin holes disposed on a drive disc. The drive disc is in communication with a lock arm which is then pivoted away from the junction of the drawer/cabinet and the surrounding cabinet housing.

A button assembly for a door lock may include a button and a shank. The button may be toollessly couplable to the shank to allow force transmission between the button and the shank. The button may transfer linear force and torque along a longitudinal axis of the button to the shank to allow a state of an associated lock body to be changed.

A positive dual-locking latch for use in combination with a door and including a latch base; a handle assembly at least partially housed within and translatable relative to the latch base; and a latch assembly mechanically coupled to the handle assembly. The handle assembly includes a handle member at least partially housed within a housing member, with the handle assembly being biased by a handle spring in a direction away from the latch base. The latch assembly includes at least one latch spring and a latch member mechanically coupled to the at least one latch spring. The handle assembly and the latch assembly are operably configured to translate the positive dual-locking latch between a first locked configuration and a second locked configuration when the handle member receives a pushing force, and between the second locked configuration and an unlocked configuration when the handle member receives a pulling force.

A door handle includes a human body detection sensor, a controller, a servo assembly, and an engaging assembly. The controller is electrically connected with the human body detection sensor and the servo assembly, and the engaging assembly is controlled by the servo assembly. The engaging assembly includes a first engaging state and a second engaging state. When the engaging assembly is in the first engaging state, the door handle is able to drive a lock body connecting shaft to rotate; and when the engaging assembly is in the second engaging state, the door handle is unable to drive the lock body connecting shaft to rotate.

A locking system for a door, including a primary locking mechanism and a secondary locking mechanism, in which the primary locking mechanism includes an electrical actuator that causes a first plate and a second plate to be magnetically attracted to one another when actuated such that rotation of a doorknob effects a corresponding rotation of the spindle, and in which the secondary locking mechanism includes a detent that is formed in a knob collar and an aperture that extends through a rotator collar; and a pin that is translatable through the aperture to be disposed in the detent of the knob collar, when the secondary locking mechanism is in an unlocked condition, such that the knob collar and the rotator collar are rotatably fixed to one another.

The utility model relates to a safe door with a recessed lock and door handle, which comprises a door plate, a door handle and a lock. The door handle is recessed and installed in a first step hole of the door plate through a first connecting structure, the lock is recessed and installed in a second step hole of the door plate, and the upper surfaces of the door handle and the lock are not higher than the upper surface of the door plate. The utility model redesigns the door plate, and sets the position where a lock disc and the door handle are installed into the form of step holes, so that the lock and the door handle are recessed and installed on the door plate.

A rotary knob for operating an electronically actuable deadbolt is described herein. According to some embodiments, the rotary knob includes a chassis, an outer wall rotatably coupled to the chassis about a central axis of the knob, a cantilevered beam attached to an inner surface of the outer wall and extending towards the central axis of the knob such that the beam is configured to rotate with the outer wall about the central axis, a circuit board coupled to the chassis, the circuit board including signal traces, and an electrical contact extending from the cantilevered beam in a direction toward the signal traces and electrically connectable with the signal traces. A controller of the rotary knob is configured to determine a position of the deadbolt based on at least the state of the electrical connection between the electrical contact and the signal traces.
