Abstract:
1. An access system for a temperature-controlled storage device, the access system comprising: a perimeter frame configured to move substantially vertically along a surface of the temperature-controlled storage device between a raised position and a lowered position, wherein moving the perimeter frame into the raised position exposes an opening into a temperature-controlled space within the temperature-controlled storage device; a plurality of substantially transparent display case doors mounted within the perimeter frame and configured to move along with the perimeter frame between the raised position and the lowered position, wherein the plurality of display case doors substantially cover the opening when the perimeter frame and the display case doors are in the lowered position and are configured to facilitate presentation of items within the temperature-controlled space, wherein each of the display case doors is configured to rotate substantially horizontally between an open position and a closed position when the perimeter frame is in the lowered position and provides access to the same temperature-controlled space through a different portion of the opening; and a torsion spring assembly coupled to the perimeter frame and configured to counteract a weight of the perimeter frame and the plurality of display case doors, wherein the torsion spring assembly is configured to store energy when the perimeter frame and the plurality of display case doors are moved into the lowered position and to release the stored energy when the perimeter frame and the plurality of display case doors are moved into the raised position.
