A door handle lock and a locking method are provided. The door handle lock comprises a first lock body, a second lock body, and a locking part, and the locking part is engaged with a movable part to lock the first lock body, thus being difficult to unlock. The door handle lock is mounted within a rotation range of the door handle, and the rotation of the door handle is limited by the first lock body. Such a setting effectively prevents a child from unlocking without permission and then opening the door to escape, thus improving the security.

A latch includes a retention portion. The retention portion is configured to prevent a first device, coupled to the latch, from being removed while the retention portion is in a first configuration. The retention portion is configured to allow the first device to be removed while the retention portion is in a second configuration. The latch also includes a spring portion configured to allow the retention portion to transition between the first configuration and the second configuration.

A child safety lock for a cupboard or drawer comprising a movable door or drawer and a fixed frame member, the safety lock comprising: a latch member, rail attachment member, a fixing screw and a catch member, the latch part to be fitted on a surface of the fixed frame member, by means of the rail attachment member and the fixing screw; the latch member including a laterally extending tongue, and the rail attachment member including a groove housing comprising a receiving groove to receive the tongue by sliding the tongue into the groove thus retaining the latch part and the rail attachment means together, and a through hole centrally in the tongue such that when tongue is located in the groove the fixing screw may be screwed through the through hole and into the groove housing this securing the latch part to the rail attachment member, the safety lock also including a C-shaped clamp with opposing clamp sides and a connecting base to fit around the fixed frame member and the rail attachment means.

A magnetic door lock control system for use with an egress handle system and a door is provided. The magnetic door lock control system employs magnets that communicate with one another across the door jamb thereby eliminating the need for a hard wired electrical connection between the egress handle system (e.g., a mechanical switch bar) configured with a door and a door locking mechanism mounted above the door in the header of the entranceway. In this way, the need for an electrical wire loop between the egress handles and the door locking mechanism is eliminated.

The present invention relates generally to the field of cabinet locks. More specifically, the present invention relates to a cabinet lock device primarily comprised of a pendulum housing, a latch housing, a catch housing release, and a door plate that can be attached to a rear door surface of a cabinet door. The door plate further receives the catch housing release. The pendulum and latch housing is further comprised of a latch and a pendulum wherein the pendulum activates a series of internal mechanisms within the pendulum and latch housing when movement of the cabinet is detected, which ultimately releases the latch into the catch housing release such that the cabinet door automatically locks in an automatic fashion. The catch housing release is further comprised of a release lever that can be used to unlock the cabinet from the outside after the device has been locked.

A reel locking device includes: a reel seat; a vertical reel rotatably connected to the reel seat and used for retracting and releasing a gate mesh; a synchronization member fixedly connected to one end of the vertical reel; an automatic locking mechanism that prevents the synchronization member from rotating freely and that includes a resettable manual unlocking slider; and an elastic pressing mechanism that obstructs the movement of the manual unlocking slider and that includes a pressing member that does not obstruct the movement of the manual unlocking slider after being pressed, and that when not pressed or after resetting obstructs the movement of the manual unlocking slider. A mesh type gate is further disclosed including the above reel seat on one side and a buckle seat on another side, where a free end of the gate mesh includes a pull ring for being fastened to the buckle seat.

A gate apparatus that includes a gate, an elongate member or gate base for the ends of the gate, and a stairway post adapter such that a wooden stairway post can serve as a base for a gate without harming the wood of the stairway post. The stairway post adapter includes a vertical or longitudinally running channel for receiving the gate base, a horizontally or laterally extending channel for receiving a strap, and a recess or receptor or face for confronting a section of a stairway post. The gate base includes an upper and lower eyelet. Each of the ends of the gate includes upper and lower pins for engaging the upper and lower eyelets of the gate bases. On the hinge side of the gate, the pins are relatively long and remain in the eyelets as the gate is lifted and swung. On the latch side of the gate, the pins are relatively short such that that latch side of the gate can be lifted and disengaged from the eyelets and then swung open. The gate is extendable and retractable in length, and is reversible.

A cabinet lock includes a latch configured to translate between extended and retracted positions and a lever configured to rotate between engaged and disengaged positions. The latch may be coupled to the lever with a pin in a corresponding slot. When the lever is in the disengaged position the latch may be in the extended position and when the lever is in the engaged position the latch may be in the retracted position. The lever includes a ferromagnetic portion responsive to a magnet within a threshold distance, where the presence of the magnet moves the lever to the engaged position.

A gate assembly including a pivoting gate element secured to a doorway and/or passageway and employing a dual actuator latching mechanism having a simple yet unique locking lever and pawl mechanism for remote and manual latch release freeing the gate to swing to an open position, and automatic re-locking of the latching mechanism. The gate assembly includes a frame element for supporting the pivoting gate element and securing the gate to a doorway and/or passageway as well as latching the gate to a closed position at the frame element.

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.
