A latch assembly for housing cover is provided. Latch assembly has switch, latch, elastic clamp, and pushbutton. Switch is disposed on first side of cover. Switch is slidable in first direction to unlocked position for unlocking latch assembly and slidable in second direction to locked position for locking latch assembly. Latch has projection for engaging and disengaging with latch slot in housing for releasably latching cover to housing. Elastic clamp has detent portion for releasable engagement with notch in second side of cover. Latch and elastic clamp are disposed on second side of cover opposite switch and coupled to switch. Pushbutton extends through aligned openings in switch, latch, and portion of elastic clamp. Latch assembly is unlocked by depressing pushbutton to impinge on elastic clamp portion, thereby disengaging detent portion from notch and by simultaneously moving the switch in the first direction.

A lock includes a pair of spaced apart parallel bolts connected by a plate extending between the bolts. A slot, formed in a hinged structure, such as a gate, extends from a free edge of the structure (an edge opposite a hinged edge) to an end point at a determined distance from the free edge. The plate is received in the slot. Each bolt is located on an opposite side of the hinged structure, when the plate is received in the slot. The slot defines a range of sliding motion of the plate and bolts.

A collinear latching and locking system is disclosed. In embodiments, the system includes a strike with a lock bolt disposed at or defined by an end of the strike. The system further includes a latch pawl configured to surround at least a portion of the strike. The strike and the latch pawl are configured to actuate linearly along the same axis. In this regard, the strike and the latch pawl have a collinear configuration and actuation path. The system further includes a latch cam configured to actuate the latch pawl from a latched position to an unlatched position when the latch cam is turned.

An arm-receiving door handle and sliding lock system, including an arm-receiving door handle assembly, including an interior plate removably connected to at least a portion of an inner surface of a door to receive a limb of a user thereon, and an exterior plate removably connected to at least a portion of an exterior surface of the door, and a sliding lock assembly, including a knob assembly removably connected to the interior plate to move laterally from unlocked in a first position to at least partially locked in a second position, and from locked in the second position to at least partially unlocked in the first position, a carrier connected to the knob assembly, and a bolt removably connected within at least a portion of the carrier to move from retracted within the carrier to at least partially extended from the carrier in response to moving the knob assembly toward the second position, and move from extended to at least partially retracted within the carrier in response to moving the knob assembly toward the first position.

A roof assembly for a convertible motor vehicle includes a roof to be placed in contact with a frame of the motor vehicle in a closed roof position, a manual locking device carried by the roof and capable of being operated by hand when the roof is in the closed roof position according to a first operating mode, in which the manual locking device cooperates with the frame to carry out a first constraining action in order to secure the roof to the frame in the closed roof position, and according to a second operating mode, in which the locking device refrains from cooperating with the frame, thus removing the first constraining action, characterized in that it further includes an additional locking device carried by the roof to automatically exert a second constraining action to secure the roof to the frame at least in response to a positioning or a movement of the roof in/to the closed roof position, the additional locking device having release means capable of being operated by hand in order to remove the second constraining action.

A door assembly for an animal enclosure includes a door frame and a door each having a plurality of interconnected horizontal and vertical wires. The door frame defines an opening for an animal to pass therethrough, and the door is slidably coupled to the door frame such that it moves between an open position and a closed position relative to the door frame to allow egress and ingress through the opening. A catch member is coupled to the door frame. A latch includes a base member, a bolt, and a lever portion. A first vertical wire and a second vertical wire of the door are spaced from one another such that the first vertical wire is at a first end of the door and the second vertical wire is at a second end of the door. In the closed position, the bolt is coupled to the first vertical wire.

An aircraft is equipped with an auxiliary access control barrier (AACB) to prevent access to an area of the aircraft. The AACB includes laterally extendable door panels that are slidably attached to each other to vary a width of the AACB, a hinge by which the door panels are pivotably attached to the aircraft, such that the door panels are pivotable between a deployed position, in which the door panels are positioned across the opening to prevent passage through the opening and in which the AACB has a first width, and a stowed position, in which the door panels are positioned to allow passage through the opening and in which the AACB has a second width, and one or more locks to prevent relative motion between the door panels to fix the width of the AACB and/or to secure the AACB within the opening in the bulkhead.
