Disclosed herein is a panelboard guard assembly configured to restrict access to a panelboard having a cover and a door defined therein, the cover having first and second side edges. The panelboard guard assembly includes overlapping members that are, at least in some implementations, mutually coupled to each other. The panelboard guard assembly further includes an adjustment mechanism that extends between and couples the members together, the adjustment mechanism facilitating adjustment of the distance between the outer ends of the members.

Disclosed are a connecting assembly, a door guardrail and a fence using the connecting assembly. The connecting assembly includes a first connector and a second connector, a transverse locking device and a longitudinal locking device are arranged between the first connector and the second connector, and the longitudinal locking device is capable of limiting relative movement of the first connector and the second connector in a transverse direction.

Methods and apparatus for using a gate latch to selectively prevent the opening of a gate barrier. The gate latch includes a retainer assembly to selectively prevent a latch member attached to a gate barrier from moving sufficiently to allow the gate barrier to swing open. A swing blocker may be provided on the same latch as the retaining assembly so that the gate may be opened only in a first direction.

A method of opening a door of a pet enclosure includes pushing a tab of a latch toward an interior of the pet enclosure with a first hand so that the door of the pet enclosure is vertically displaceable. The method further includes vertically lifting the door with a second hand so that a horizontal wire rod of the door is traversed in front of the tab. The method further includes rotating the door from a closed position to an opened position.

A guide-type actuator assembly is disclosed, which includes a guiding actuator member having a body and at least one corresponding actuating section. The body is used to couple with a first object and cause a second object to move relative to the at least one corresponding actuating section. With these arrangements, at least two objects can be quickly connected together and easily disconnected from one another.

The storage box includes: a box body having an opening toward a vehicle upper side; a fixed lid provided on a vehicle rear side of the opening; a movable lid provided on a vehicle front side of the opening; first shafts provided on a vehicle front side of the movable lid; a second shaft provided on a vehicle rear side of the movable lid; and a guide including first rails guiding the first shafts and second rails guiding the second shafts, to move the movable lid from a fully-closed position to a fully-opened position through a sliding operation and a turning operation. The second rails include slope portions guiding the second shaft so that the movable lid moves to an inner side of the box body relative to the fixed lid when the movable lid starts the sliding operation from the fully-closed position.

A latching mechanism having a camming surface to engage the latching mechanism without human intervention when a door is traversed from an opened position to a closed position is disclosed. Other latching mechanisms are also disclosed. The latching mechanism may also be rotatable to engage the latching mechanism and prevent opening of the door from the closed position.
