Abstract: A door for an arc-resistant compartment includes an opening there-through. Flap structure includes a flap member coupled to the door and movable between an opened position permitting air to pass through the opening, and a closed position covering the opening. Spring structure is engaged with the flap member to bias the flap member to the closed position. Handle structure is coupled to the flap member and extends through the door for moving the flap member to the opened position against the bias of the spring structure. Retaining structure provides a retaining force on the flap member to retain the flap member in the open position, against the bias of the spring structure. During an arcing event in the compartment, pressure within the compartment together with the bias of the spring structure overcomes the retaining force to automatically move the flap member to the closed position.

Abstract: To open the two-action gate, a sliding of a latch and a lifting to disengage a double stop is required. Performing one step without the other fails to open the gate. The gate is engaged in a frame which may in turn be engaged in a partition or “inside the home” fence or other barrier. Via a thumb tab with the rest of the hand holding onto the top tube of the gate, a portion of the latch can be slid out of the frame. Then the hand may lift up the gate to lift a double stop up and clear of a lower portion of the frame such that the gate is swingable. Once the double stop is clear of the lower portion of the frame and the gate has been swung several degrees, the gate may be lowered and then swung at will. The two steps of sliding and lifting minimize the chance that children can open the gate.
