Abstract: A cam mechanism has different portions thereof arranged on a main unit, which may be a refrigerator, and on a door. When the door is closed, a hinge pin is locked at one end of a hinge groove, keeping the cam mechanism in a first locked position. As the door is opened, the hinge pin is guided by the hinge groove and a guide pin is guided by a guide groove, permitting the door to rotate and slide. Thus, the hinge pin is locked at the other end of the hinge groove, bringing the cam mechanism to a second locked position. A boss slides on a rib and thereby maintains the second locked position, permitting the door to rotate about the hinge pin. This structure helps realize a door opening/closing mechanism with enhanced operability at reduced cost.

Abstract: A hinge assembly allows an access panel to be pivotally coupled to a cabinet, even though the cabinet includes a top cover that overlaps an upper edge of the panel. To open the access panel, a latch is actuated to first release a lower edge of the panel. The hinge assembly then allows the lower edge to be pulled out from over a base rail of the cabinet. Once the lower edge is off of the base rail, the hinge assembly allows the panel to be lowered without obstruction from the base rail. Lowering the panel then moves the panel's upper edge out from underneath the overlapping top cover. From there, the hinge assembly allows the panel to be swung open. To close the access panel, the process is reversed.
