Abstract
A cabinet is provided with a curved, upwardly-swinging door and interior shelves. The curved shelf door is mounted on a pair of opposed pivot arms which rotate on a horizontal axis. Each pivot arm is provided with a disk portion having a central boss and an arm portion tangent to the disk portion. The central boss engages a fixed stud at the side of the cabinet and provides a center pivot for each of the arms. A gas spring for each arm is provided, which is pivotably connected at one end to the arm and at the other end to a side wall of the cabinet. The gas spring serves a dual purpose of counterbalancing the door as it moves between an open and a closed position and opening the door unassisted once the user initiates movement of the door, this opening feature being very beneficial to seated and physically disabled users.
