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 includes a lock with a latch. An inside face plate and an outside face plate of the door lock are respectively mounted to an inside plate and an outside plate of the door lock. A washer plate is sandwiched between the inside face plate and the outside face plate. An inside cylinder and an outside cylinder are connected between the inside plate and the outside plate. An inside collar is connected between the inside face plate and the inside cylinder, and an outside collar is connected between the outside face plate and the outside cylinder. When the door lock is set in ready-to-open mold, the door can be opened by either rotating the shafts or the door handle by one hand. When the door lock is set in locked mold, the door cannot be opened by simply rotating the door handle.

The invention relates to a lock including a locking mechanism having a latch that is movable between a latched position, which is provided for securing a counter-piece movable relative to the locking mechanism, and an unlatched position provided for releasing the counter-piece, and having an actuation element for manually moving the latch into the unlatched position. The lock furthermore includes a coupling element that can be transferred between a coupled state, in which it is coupled to the latch, and a decoupled state, in which it is movable relative to the latch, and that can be moved from a passive position into an active position by means of the actuation element, wherein the latch can be moved into the unlatched position by a movement of the coupling element, which is in the coupled state, from the passive position into the active position by the actuation element.

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 mechanism for selectively coupling a first moving part with a second moving part. The mechanism includes and engaging member that is movable between a detent position, a uncoupled position, and a coupled position in which the load transferring surface is within the aperture. A biasing member biases the engaging member into the detent position or coupled position. The engaging member overrides the biasing force and moves out of the detent position into the uncoupled position when first and second moving parts move relative to each other. When the engaging member is in the coupled position, the first and second moving parts are coupled for movement together. One embodiment of the invention is a child safety door handle rotating on a spindle. Other embodiments include water faucets, stove or burner controls, or any other rotatable or movable parts.

A handle set including a chassis and a handle mounted on the chassis. The handle includes a shank having a load bearing section, a primary actuating section, and a secondary actuating section. The chassis includes a housing, a support spindle, a primary actuator, and a secondary actuator. The support spindle is longitudinally coupled with the load bearing section, and the primary actuator is rotationally coupled with the primary actuating section of the handle. The handle set has a first configuration in which the secondary actuating section is engaged with the secondary actuator, and a second configuration in which the secondary actuating section is disengaged from the secondary actuator.
