A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

A lock, a fitting and a strike plate, in addition to a closing device for sliding doors, allow frontal or lateral locking of a sliding door. Further a sliding door system has a closing device.

The present disclosure relates to a locking assembly for locking at least one second body to a first body. The first body may have at least one accommodating cavity for accommodating the at least one second body respectively. The locking assembly may include a knob on the first body and a pushing device between the knob and the first body. The knob may be configured to rotate around an axis to switch the locking assembly between a locked state and an unlocked state. The pushing device may be configured to apply an elastic pressing force on the knob in a direction away from the first body during rotation of the knob.

A dynamic lock mechanism includes a lock body defining a longitudinal axis, the lock body including an opening extending from a first end of the lock body to a second end of the lock body, a lock plunger configured to travel within the opening in the lock body such that the lock plunger is enclosed within the opening when the lock plunger is in a first position and at least a portion of the lock plunger extends out of the opening when the lock plunger is in a second position, the lock plunger including a retention channel, a catch member disposed within the lock body and configured to engage with the retention channel of the lock plunger when the lock plunger is in the second position, and a first tensionable member coupled to the lock plunger and a second tensionable member coupled to the catch member.

A screwless strike assembly for a lock includes a box body provided with side wall elements that bound a cavity that is suitable for receiving a latch or a bolt of the lock. The box body is suitable for being positioned in a housing seat of a frame of a door or another support element. The assembly includes a front plate, provided with a passage opening for the latch or bolt, and formed according to the geometrical shape of the box body. The assembly is provided with elements for fixing in the housing seat. The fixing elements include one or more locking arms integrally obtained on, and protruding from the rear of front plate, and elastically yieldable from a rest configuration to a spreadable fixing configuration in which they engage a bounding surface of the housing seat. The box body includes one or more pushing surfaces configured for spreading and pressing one or more locking arms against the bounding surface to achieve the spreading fixing configuration.

An auto-latching latch assembly is mounted to a follower door of a double door. The latch assembly includes a latch movable between an unlatching position and a latching position and a movable member jointly movable with the latch. A positioning member is jointly pivotable with the movable member. When the latch moves to the unlatching position, the positioning member positions the latch in the unlatching position. When the follower door is closed while a primary door of the double door is closed, an actuation latch presses against and releases the positioning member to move the latch to the latching position, reliably locking the follower door.

A multipoint lock assembly for a swinging door panel includes a mortise housing that is installed in a mortise along the non-hinged edge of the door panel. A latch operating mechanism and a lock operating mechanism are disposed in the mortise housing. Each of these mechanisms is designed to be operated with a standard rotary operator such as a handle or knob for the latch operating mechanism and a key and/or thumb turn for the lock operating mechanism. The latch operating mechanism is transitionable between left- and right-hand orientations and includes a deadlatch feature that prevents forced back-drive. Turning the key and or thumb turn of the lock operating mechanism extends a deadbolt and extends upper and lower shoot bolts from edges of the door. When extended, the shoot bolts also are secured against forced back-drive by unique mechanism configurations.

Locks for storage containers having closures such as doors, covers or lids are disclosed. The lock is mounted to the closure and is latched in such a manner as to selectively prevent opening or removal of the closure. The latch of the lock can engage a slot in the storage container, a bracket on the storage container, or a strike on the storage container. Alternatively, the latch can engage a mounting bracket on the door or other portion of the door to selectively block movement of a handle for the door. Further, the latch can have a locking device which can selectively block movement of the latch. Movement of the locking device can be selectively controlled by a magnetic key.

An electronic lock with an electronic sensing arrangement to accurately sense relative positions of a bolt which mechanically locks a door, such as a door of an electronic drop safe, and to also sense an electronically controlled plunger which locks the bolt in place. The arrangement provides a mechanism for sensing a variety of mechanical malfunctions, as well as, potential fraud or tampering situations.

A tamper-proof lock includes: a housing, shaft/handle, cam, lever, spring, and plate. The shaft is pivotally mounted in a housing orifice, with the cam pivotally mounted to the shaft. The cam has first and second shaped openings at first and second respective radial positions, and an arcuate recess. The lever is secured to the shaft, and has a protrusion that alternately engages each of first and second ends of the arcuate recess to respectively/selectively drive the cam to rotate/counter-rotate in first and second directions, into locked and unlocked cam positions. The spring biases the plate for a protrusion thereon to be respectively received within each of first and second shaped cam openings, when aligned therewith at those cam positions, and for a curved surface of the plate to be correspondingly received within first and second curved cam recesses, respectively, when aligned therewith, which facilitate withdrawal of the plate protrusion.
