A door lock has an inner door assembly, an indoor doorknob assembly, and an outdoor doorknob assembly. The inner door assembly has a locking assembly casing. The indoor doorknob assembly has a positioning resilient component located in the locking assembly casing and configured to switch the door lock between a locked state and an unlocked state. The door is provided with enhanced protection by enclosing the positioning resilient component in the locking assembly casing, so the safety is further improved.

An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.

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.

Disclosed is a closure for a door of a shipping container. The closure includes a housing, an outside handle pivotally mounted relative to the housing, an inside handle pivotally mounted relative to the housing, and a catch connected to the inside handle. The closure is configured so that movement of the inside handle between a first position and a second position causes corresponding movement of the catch. A locking mechanism can releasably fix the inside handle relative to the outside handle, such that when in a locked position rotation of the outside handle causes corresponding rotation of the inside handle and when in an unlocked position the inside handle can be rotated independently of the outside handle.

A locking mechanism is provided for a portal closure that includes a first side, and a second side The portal closure including a latch movable into and out of engagement with a latch receiver and a latch driving device coupled to the latch for moving the latch into and out of engagement with the latch receiver The latch driving device includes a controllable lock member movable between a locked position where the latch is fixedly positioned in the latch receiver and an unlocked position where the latch is capable of being disengaged from the latch receiver and a second side latch driving device mover disposed on the second side of the portal closure. The locking mechanism includes a first side latch driving device mover disposed on the first side of the portal closures, and coupled to the latch driving device for moving the latch driving device to cause the latch to move into and out of engagement with the latch receiver. A signal generator is provided for generating a human detectable signal. A lock actuator is coupled to the controllable lock member for moving the locking mechanism between a first normal position wherein the second side lock driving device is capable of being moved between an unlocked position to permit the latch to be disengaged from the latch receiver and a locked position where the latch is prevented from being disengaged from the latch receiver; and a second emergency position wherein the second side lock driving device is in the locked position, and the signal generator is actuated to generate a human detectable signal. A power source is provided for powering the signal generator when the locking mechanism is in the second emergency position. A switch is coupled between the power source and the signal generator for controlling the flow of current between the power source and the signal generator.

A handle assembly for a window or door leaf having first and second opposing sides, the handle assembly having a forward end and a rearward end, the handle assembly comprising: a first handle grip, configured for mounting to a first side of the leaf, the first handle grip being moveable rotatably and axially relative to a first handle axis, and a second handle grip configured for mounting to the second side of the leaf, the second handle grip being movable at least rotatably relative to a second handle axis, each handle grip having a closed position, wherein the handle grip is in a first angular position and an open position, wherein the handle grip is in a second angular position, the handle assembly having a rest mode and a locked mode.

An opening device for a door lock is provided. The opening device includes a driver rigidly connected to an inside handle; an inside shaft designed to rotate an internal latching mechanism of the door lock, the inside shaft having a follower and a through cavity; a first gear engaged rotationally to the driver; an outside shaft designed to be rotated by an outside handle, the outside shaft including a cylindrical part disposed inside the through cavity of the inside shaft, a polyhedral part engaged with the outside handle, and a gear seat located at end of the cylindrical part and outside of the inside shaft; a second gear slidable along the gear seat; an engagement mechanism causing the first gear and the second gear to be engaged, thereby causing the driver to engage the follower, which causes the inside shaft to rotate in response to rotation of the outside shaft.

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 latch for a motor vehicle compartment includes a latch pawl having a locked position and an unlocked position, the locked position preventing access to the compartment, the unlocked position providing access to the compartment, and an actuator that rotates about a first pivot point. The actuator selectively engages with the latch pawl to move the latch pawl from the locked position to the unlocked position.

The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle (20) is connected to the rotor (30) so as to transmit a torque and is held on the rotor (30) by a clamping spring (50). The clamping spring (50) has a receiving area for a magnet (60). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle (20) and the rotor (30) is triggered by an external influence on the magnet (60) (FIG. 1).
