A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.

A corral gate latch release device facilitates quick release of a corral gate latch without a user having to dismount from a horse. The device includes a gate door and a latch coupled to and extending from the gate door. A base post is positioned adjacent to the gate door when the gate door is in a closed position. A latch lock is positioned on the base post to engage the latch when the gate door is in the closed position. A linkage is coupled to the base post and is operationally coupled to the latch lock to disengage the latch lock from the latch. A grip arm is operationally coupled to the linkage to be grasped to move the linkage for disengaging the latch lock from the latch.

A door security device for an out-swing door includes a mounting plate secured to the door, a hinge pin assembly supported by the mounting plate proximate the door outside edge, a clasp swing plate secured to the hinge pin assembly for pivotal movement between unlocked and locked positions, a door frame anchor bolt received in a clasp cut-out of the clasp swing plate captured behind an enlarged anchor bolt head in the locked position in a lowermost position of the clasp swing plate, the clasp swing plate biased by force of gravity to the lowermost position, and the mounting plate having a first receiver top surface at the hinge pin vertical axis, the first receiver top surface defining the uppermost position of the clasp swing plate in an unlocked position parallel to the mounting plate and defining the lowermost position of the clasp swing plate in the unlocked position perpendicular to the mounting plate.

Safes and related locking assemblies, mechanisms, and enclosures. In some embodiments, the locking mechanism may comprise one or more fixed locking members, such as studs, mounted on or otherwise coupled to the body of the safe or other enclosure, such as a box, building, vehicle, trailer or the like. In some embodiments, the locking members may be mounted to the door/lid frame of the enclosure. Additional moveable locking members may be positioned on and/or moveably coupled with the safe door, which may allow the moveable locking members to engage the fixed locking members on the door frame to lock the door/lid in place.

A latch mechanism includes a first and second latch body. The first and second latch body respectively includes a first and second base, a first and second latch portion and a first and second acting portion. The first latch body disposes through the second base. The second acting portion is pivoted to the second base. The second latch portion is disposed on the rotational path and limited to the first latch portion. The second acting portion includes a first and a second pushing structure. When the second acting portion is rotated along the rotational path, the second latch portion is pushed by the first pushing structure such that the second latch portion is disengaged from the first latch portion, and then the first acting portion is pushed by the second pushing structure such that the first latch body is disengaged from the second latch body in a releasing direction.

A safety switch comprises a switching device having a casing housing electric and/or electronic control means adapted to be connected with one or more circuits, an operating device adapted to be anchored to a movable part of the access to interact with the switching means when the access is opened/closed for the opening/closure of the circuits, means for detecting the opening of the access associated with the switching device and with the operating device for sending a stop command of the machine or plant upon the detection or request for the opening of the access, driving means for sending activation/deactivation and/or signalling controls and that comprise a touch monitor provided with one or more virtual controls and at least one microprocessor suitable for associating the virtual controls with a control and/or signalling function.

The invention discloses a locking device and a refrigerator, wherein the locking device comprises a first lock block and a second lock block; the first lock block comprises a base and a tongue; the second lock block comprises an accommodating cavity, a clamping block, a return spring and a pushing block; the pushing block pushes the clamping block to slide in the sliding groove; and the tongue enters the tongue channel to be engaged with the clamping block so that the two lock blocks are engaged with each other. The locking device has the function of automatically adjusting the height difference between different cabinet doors and cabinet bodies, and is therefore more flexibly suitable for locking various cabinets or refrigerators.

A gate latch pull system for a swinging gate and gate post. A gate latch with pivotal latch lever is mounted on a gate post and a latch bar on an inside edge of a swinging gate. A T shaped lever with first and second lever arms and a swinging base is pivotally mounted on the gate post above the gate latch. A vertical linkage connectable between bottom of swinging base and top of the pivotal latch lever, with the linkage adjustable in length during connection of the base and the latch lever such that when the latch lever is in a latched position and the swinging base is vertical, the linkage has flexibility, slack and weight enough to provide additional downward weight bias to pivotal motion of the latch lever.

An intelligent lock and latch system which may include a housing that can be coupled to a post. The system employs a latch pin that can coupled to a gate and used in connection with the housing to secure the gate. The housing can further comprise a front cavity, a back cavity, one or more mounting holes, a slot, and a recess. The housing can be coupled to the post by one or more fasteners through the housing's mounting holes or using a mounting adapter. The intelligent lock and latch system can further comprise a back cover supporting gears, an electrical system and motor to power the gears, and a keypad to operate the system that be a standalone system or can communicate through wireless communication to a hub or mobile device.
