ABSTRACT:
A cabinet (10) comprises a top wall (12), bottom wall (14), two identical side walls (16), each having a front edge (18), and a back wall (20), the walls (12, 14, 16, 20) defining a front opening (22). A flipper door (24) is adapted to cover the opening (22) and the front edges (18) of the side walls (16) when the flipper door (24) is in the closed position. To this end, the width of the flipper door (24) is greater than the distance between the sidewalls (16) of the cabinet (10). In addition, the flipper door (24) is suspended by a rack-and-pinion assembly (26) which includes racks (30) secured to the side walls (16) and pinion gears (36) rotatably engaging the racks (30). The pinion gears (36) are coupled together by an axle (40). The ends of the axle (40) engage lower guide channels (34) in the racks (30). Pivot links (46) are pivotally coupled to the ends of the axle (40) between the pinion gears (36) and the racks (30). The pivot links (46) are also pivotally connected to flipper door brackets (52) through stud shafts (62) mounted to the brackets (52) and pivotally connected to the pivot links (46). The stud shafts (62) ride in upper guide channels (42) in the racks (30). The flipper door brackets (52) are rigidly secured to the flipper door (24). When the flipper door (24) is moved to its forward-most position, the links (46) operate to offset and translate forwardly and upwardly the pivot axis of the flipper door (24) to enable the flipper door (24) to close over opening (22) and the front edges (18) of the side walls (16).
