Abstract
Abstract An up-down cabinet for lowering a cabinet from a wall so that easy access is provided to the cabinet. The cabinet is normally disposed adjacent the wall. By urging the cabinet away from the wall the cabinet pivots outwardly and downwardly on pivotally attached swing arms. The swing arms are attached to cables resting on cable pulleys. The cables are held in tension by coil springs. By applying tension on the cables the cabinet is easily retracted upwardly and rearwardly to its normal position against the wall.
