ABSTRACT:
A top access cabinet (12) includes a cover (18) pivotably mounted thereto by a hinge and lever arrangement which permits the cover to pivot and slide with respect to the cabinet so that the cover can drop behind the rear wall of the cabinet when the cover is opened. Hinges (54) mount the cover (18) to the cabinet (12) along the rear wall (22) of the cabinet (12). Elongate slide members (60, 62) supported by the hinges (54) slidably mount channel members (56, 58) secured to the underside of the cover. Lever arms (32) disposed on each side of the cover (18) are mounted between the side walls (24, 26) of the cabinet and the cover. When the cover is raised, the lever arms (32) displace the cover (18) relative to the cabinet so that the channel (56, 58) members slide over the slide members (60, 62). Since the cover is slidably mounted relative to the cabinet, the lever arms (32) displace it rearwardly when lifted so that the cover is moved to a position behind the rear wall of the cabinet and thereby provide free access to the interior of the container. In order to slow descent of the cover and eliminate excessive wear on the hinges and levers, a spring-biased retarding mechanism (44) or equalizer including a stop member (86) is mounted to the cover (18).
