A locking assembly having a bolt carrier and a bolt receiver is disclosed. The locking assembly may include a T-shaped bolt that engages with the bolt carrier and the bolt receiver to lock or unlock a door. The T-shaped bolt may slide between an engaged and disengaged position. The locking assembly may further include an access box that may move between a locked position and an unlocked position, and a cable configured to extend from a back side to a front side of the door via a door hole. The cable may include a first cable end that engages with the T-shaped bolt, and a second cable end that may be inserted and positioned in an access box interior portion. The second cable end may be pulled via the access box to slide the T-shaped bolt from the engaged position to the disengaged position.

The disclosure relates to a child safety lock mechanism for a cupboard, the cupboard includes at least one movable door and fixed frame, the locking mechanical system includes an external section arranged on the outside of the cupboard door, an internal section secured to a part of the frame, a latching means and a releasing means, wherein the external section is removably lockable to the internal section by the latching means and releasable by the releasing means. The latching means and releasing means are mutually engageable to release the latch, and extend from a first surface of the door to a second surface of the door to effect the engagement.

An apparatus is provided that includes a base defining a cavity; a lid coupled to the base; a latch; and a resilient member. The lid is pivotable between a first state in which the cavity is enclosed and a second state in which the cavity is exposed. The latch includes a first portion, a second portion, and a third portion. Each of the second and third portions interact with the base when the lid is in the first position so as to discourage the lid from transitioning to the second state. The resilient member is disposed between the latch and the lid such that moving the first portion of the latch so as to compress the resilient member moves each of the second and third portions of the latch away from the base.

The latching means and releasing means are mutually engageable to release the latch, and extend from a first surface of the door to a second surface of the door to effect the engagement.

The invention relates to a device (200) for locking a door, which comprises: a bolt (40) comprising a bar (52) configured to engage in a housing secured to the frame (80) accommodating the door and a pusher means secured to the bar (41) and spaced apart from the bar by a stem and in which the bolt is positioned on the door at a height relative to the foot of the door of between thirty and eighty centimetres, such that the bar of the bolt can be engaged with or disengaged from the housing secured to the frame by pressure applied by a user's knee against the pusher means.

A door lock system includes a first component mounted on one side of a door and a second component mounted on the opposite side. The system features a structure that mechanically connects the two components, designed to pass through the gap between the closed door and its frame. Additionally, the system incorporates a communication link between the first and second components.

A gate assembly includes a base member, a door cover member, and an operating member. The door cover member is arranged on the base member, and includes a body, a movable portion, and two gate portions. The body is provided with a through slot and two protruding posts. The movable portion is arranged on the body and is movable relative to the body along a first axis. The movable portion is provided with two limiting posts and an accommodating portion. Two gate portions are movably arranged on the body and the movable portion. Each of the gate portions is provided with a limiting hole formed in an inclined direction and a positioning hole formed along a second axis orthogonal to the first axis. Each of the limiting posts extends through the limiting hole, and each of the protruding posts extends through the positioning hole.
