Abstract: A storage cabinet is provided with a front opening for access to the interior thereof, and a door is coupled to the cabinet for movement between a closed position wherein the door extends vertically across the access opening, and an open storage position wherein the door is disposed generally horizontally and is positioned at least in partial overlapping relationship directly over the cabinet top wall. A pair of support mechanisms couple the door to the cabinet housing adjacent the upper corners thereof. The support mechanism includes an intermediate support member which is hinged on a bracket secured adjacent the front edge of the housing top wall for swinging movement about a horizontal hinge axis which is located adjacent the front edge of the top wall. A gear is rotatably supported on the intermediate support member with its rotational axis being spaced radially from the hinge axis.

Abstract: An adjustable auxiliary work support assembly which includes a shelflike auxiliary support connected to one end of a parallelogram linkage. The other end of the linkage is connected to a carriage which is slidably supported within a guide rail fixed to the underside of a main support. The linkage enables the auxiliary support to be vertically swung upwardly and downwardly. A cam structure includes first and second cams respectively fixed to the rail and linkage, and a cam follower pivotally mounted on the carriage and cooperating between the cams to effect automatic lowering of the auxiliary support when the latter is closely adjacent the front edge of the main support and is pushed inwardly toward the latter. The cam structure also includes a pair of side cams fixed to the carriage in strattling relationship to the cam follower, and which cooperate with the fixed cam on the linkage to effect automatic lowering of the linkage when it is pivotally swung sidewardly beyond a permissible angular extent.
