  • Slide interlock and cabinet stabilizer
    Patent number: 4372632
    Abstract: A locking and bracing apparatus, comprising a vertically movable interlock bar and a horizontally movable outrigger-type support brace, is mounted to a cabinet having a drawer. When the brace is in a stored position within the cabinet or in any position intermediate the stored position and a fully extended position, a peg which is on the interlock bar and slidably rides over the brace keeps the interlock bar in a raised position whereby the drawer is locked in a closed position within the cabinet. When the brace is in the fully extended position to support the cabinet from tipping, the peg is disposed in a hole formed in the brace so that the brace is locked in the extended position and the interlock bar is in a lowered position whereby the drawer is unlocked. Thereafter, if the drawer is pulled outward from the cabinet, the interlock bar is blocked by the drawer from being moved from the lowered position so that the brace remains locked in the extended position.
