An exemplary deadbolt includes a pair of rollers positioned on opposing sides of an axial centerline of the deadbolt. The deadbolt may include chamfers or tapered surfaces extending from side surfaces of the deadbolt toward a face of the deadbolt. The rollers may extend beyond the face, one of the side surfaces, and/or one of the tapered surfaces. As the bolt moves from a retracted position to an extended position, one of the rollers may engage an edge of an opening in a strike plate, for example when the deadbolt is misaligned with the strike plate opening. As the rollers engage the edge, the deadbolt may be urged to a more aligned position.

A lock system may comprise a lock assembly including a locking element movable between locking and unlocking positions, and a first lock actuating assembly configured to be mechanically operated to actuate the locking element to move between the locking and unlocking positions, with mechanical operation of the first lock actuation assembly occurring through a physical object. The system may also comprise a second lock actuating assembly configured to be electrically operated to actuate the locking element to move between the retracted and extended positions, with electrical operation of the second lock actuating assembly occurring through reception of a wireless signal by the second lock actuating assembly. The lock and lock actuating assemblies may have at least one mode of operation characterized by the lock assembly being actuated only by substantially simultaneous operation of the first lock actuating assembly and operation of the second lock actuating assembly.

A system is provided for securing a lid of a container to prevent animal intrusion that includes a container, a lid, and a mechanism for securing the lid in a closed position. In an embodiment, the mechanism includes a gravity-actuated swivel lock for locking the mechanism when the container is tilted from a preferred orientation. In another embodiment, the system includes a mechanical claw configured to press at least one release lever for releasing the container lid, while grasping the container for lifting and tilting, to empty the container contents into a garbage truck.

Disclosed is a side-by-side refrigerator. The side-by-side refrigerator include a refrigerator body, the interior of the refrigerator body being provided with a refrigerating compartment; a first door body and a second door body, and the first door body and the second door body are respectively arranged on the refrigerator body to jointly open and close the refrigerating compartment, the first door body is provided with a first door seal, and the second door body is provided with a second door seal, and a door body locking assembly, and the first door body and the second door body are locked by the door body locking assembly when the refrigerating compartment is closed, and the first door seal and the second door seal jointly seal a gap between the first door body and the second door body.

An improved surface bolt having a one-piece bolt and, in some embodiments, a one piece channel base in which the bolt is slidably mountable. In some embodiments, the channel base has first and second opposing edges with sidewalls along the edges, and each sidewall has a lip overhanging the base to define a groove or slot. The bolt has first and second opposing edges with ridges that slidably mount within the grooves. The bolt can include a handle extending from a first bolt member surface and a bumper extending from an opposed second bolt member surface and constraining sliding movement of the bolt between fastener heads or other stops extending from the channel base. Some embodiments of the bolt and channel base are made of a lightweight material such as plastic for example; and the bolt and channel base can include scoring, allowing their size to be altered at the score lines.

Systems, apparatuses, and methods provide for technology that moves a vent panel into a pressurization position to close a depressurization vent to allow an apparatus to be pressurized. In the pressurization position, a first protrusion abuts a door structure. The vent panel is coupled with the first protrusion. The technology moves the vent panel to a depressurization position to open the depressurization vent to depressurize the apparatus. In the depressurization position the first protrusion is separated from the door structure. The technology moves the vent panel to an intermediate position between the pressurization position and the depressurization position. In the intermediate position the first protrusion abuts the door structure.

The present invention relates to a locking device with arrangement for selecting an active side of a door, the locking device comprising a first side configured to face a first side of a door and a second side configured to face a second side of a door when the locking device is mounted in the door, a bolt that is configured to move between an extended position and a retracted position, said movement being in a direction parallel to the first side and the second side, and a bolt operating mechanism configured to control a position of the bolt, and the arrangement comprising a first handle receiving portion arranged on the first side of the locking device, and configured to rotate when a first handle is operated, a second handle receiving portion arranged on the second side of the locking device, and configured to rotate when a second handle is operated, wherein the first handle receiving portion and the second handle receiving portion are configured to move independently of each other; the arrangement also comprising a connector configured to transmit a movement from the first handle receiving portion or the second handle receiving portion to the bolt operating mechanism of the locking device; an actuator movable from a first position, in which it connects the first handle receiving portion to the connector to a second position in which it connects the second handle receiving portion to the connector, so that a rotation of the first handle receiving portion or second handle receiving portion is configured to generate a movement of the bolt; and a fastening device configured to fixate the actuator in the first position or the second position, wherein the fastening device is configured to be accessible from a third side of the locking device, said third side being essentially perpendicular to the first and second side.

Disclosed, in some embodiments, is a latch assembly mountable to a structure for securing a moveable barrier in a closed position. The latch assembly comprising a latching unit with a displaceable latch pin, and a retractable actuator mounted in a housing of the latching unit. The retractable actuator being moveable along a latch axis to move the latch pin towards a retracted position to enable the moveable barrier to be moveable from the closed position. The retractable actuator including an elongate body extending between opposing ends, and a knob being formed separate to the elongate body and mounted thereon via a mounting arrangement. Also disclosed, in some embodiments, is a receiver unit having a magnet for attracting the latch pin the latch pin towards a displaced position. The receiver unit including a receiver body and a carrier, the receiver body including an interior surface defining a cavity for receiving the carrier therein. The carrier being configured for retaining the magnet. The carrier includes at least one retention portion
