Publication number: 20030151334Abstract: A computer enclosure includes a base (10), a hood (30), a pair of locating plates (50), a pair of positioning plates (60), and a pair of connecting mechanisms (70). The hood includes a top cover (32), and a bezel (38) perpendicularly attached to an end of the top cover. The locating plates are secured to opposite sides of the base. The positioning plates are secured to opposite sides of the hood near the bezel. The connecting mechanisms are disposed between the base and the hood, and pivotably connected with the locating plates and the positioning plates. The hood is thereby pivotably secured to the base.Type: ApplicationFiled: April 22, 2002Publication date: August 14, 2003Inventors: Jung-Chi Chen, Yun-Lung Chen

Publication number: 20030151339Abstract: A refrigeration unit with improved storage and accessibility features has a thermally insulated cabinet and door defining a storage space with a plurality of support elements. The support elements include easily removable door shelves and horizontal cabinet shelves that can be removed or repositioned without the door being fully opened due to dished regions adjacent the shelf supports that allow the shelves to be pivoted and removed rather than slid straight out of the cabinet. Indicia on one of the shelves follows the contour of one of the door shelves to indicate approximately the shelf space occupied by an adjacent door shelf and thus where items can be set without interfering with the closure of the door. The refrigeration unit also includes a cam assembly at the lower door hinge which biases the door closed when open approximately 35 degrees or less. The refrigeration unit also includes features for attaching an overlay panel to the door easily.Type: ApplicationFiled: February 14, 2002Publication date: August 14, 2003Inventors: William A.
