A magnetic self-latching device for a gate has a main body with handles on either side for operation or has an arrangement to be remotely actuated. A latching body has a high strength magnet usually provided at the bottom of a cavity which defines a latching shoulder. The latching body is adapted to be fixed to a gate post. The main body, with its housing, can be mounted on the gate frame and incorporates a latch pin which, in the door-closed position, is displaced by magnetic attraction to an extended latching position and against the biasing of a return spring. The gate cannot be opened until actuation of the mechanism occurs, for example by rotating a handle to retract the pin against the magnetic force; the gate can then be swung open. When the handle is released, the biasing spring retains the latch pin in a retracted position.

A door-locking mechanism is for locking a door of a cabinet with respect to a main body of the cabinet. The door-locking mechanism includes a supporting component being operatively mountable onto the door, a driving component being operatively moveable with respect to the supporting component between at least first and second configurations, and at least one transmission component being operatively moveable with respect to the supporting component between drawn-in and drawn-out configurations. The door-locking mechanism also includes at least one locking rod being operatively connectable to the at least one transmission component and being movable between disengaged and engaged configurations with respect to a corresponding catch-rod of the cabinet, in response to the at least one transmission component being operated between the drawn-in and drawn-out configurations respectively, via an operation of the driving component from the first to the second configuration.

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 lockset (10) is actuable by pivoting a lever (14,16) about a longitudinal axis of the lockset (10) by rotating the lever (14,16) and by pivoting the lever (14,16) about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset (10) includes an inside lever (14) and an outside lever (16), each associated with an independent mechanism, each of which can independently actuate the lockset (10). A keyed locking cylinder (250) is disposed axially in the outside lever (16) and pivots with the outside lever (16). The keyed lock cylinder (250) has an opening that pivotably engages an actuator (260). The actuator (260) extends into a retractor assembly (33) of the lockset (10) and is configured to perform an unlocking or locking function when actuated.

A door latch which provides leverage to the door in both the closing and opening operations of the latch's door handle. The door latch has a door axle attached to an edge of the door and a striker is attached to the cabinet. A latch pivoting component has a base bearing journaled to the door axle and a handle attached to the base bearing for manually rotating the base bearing about the door axle. A cam is attached to the base bearing and is engageable with the striker by rotation of the base bearing. The cam includes a closing cam segment and an opening cam segment. The opening cam segment engages and slides along the striker as the latch pivoting component is rotated in an opening direction of rotation. The closing cam segment engages and slides along the striker as the latch pivoting component is rotated in a closing direction of rotation.

A retractor assembly for a cylindrical lockset comprises inner and outer retractors. Each of the retractors has a cam engaging surface to convert rotary motion from the inside door handle into linear latch-retracting motion. Inner and outer spindles having retractor activation cams are configured to bear upon cam surfaces of the inner and outer retractors to retract the latch. When the inner door handle is operated, the inner retractor acts directly upon the tailpiece of the latch bolt assembly to retract the latch. When the outer door handle is operated, the outer retractor presses on the inner retractor, causing it to retract the latch. If there is an attack, a blocker assembly engages with members formed in the outer retractor to render the outer retractor inoperative to move into a latch-retracting position without interfering with operation of the inner retractor to move into a latch-retracting position.

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.

A control unit 1 for the lock of a safe having a front housing part 4 and a rear h housing part 3. A controller 6 is integrated in the control unit 1 that, when a correct combination is entered in the keypad 5, moves a module through a motor 11 in the number of turns corresponding with this combination. The module has a transmission board 8 integrated in the housing 2 of the control unit 1 and a bolt 9 for actuating the safe's lock.

A handle locking structure includes a handle having a pivot portion pivotally connected to a sliding box, a buckle portion for hooking on a cabinet and a handle shaft, and a positioning structure including a base connected to the handle shaft, a positioning device mounted in the base and an elastic member placed on the positioning device. When the handle is hooked on the cabinet, a peripheral limiter of a head member of the positioning device is disengaged from a position-limiting notch of the base to reset the elastic member, so that the positioning device is automatically locked to the sliding box, avoiding vibration of the handle and improving the locking stability of the handle.
