Abstract
Abstract A foldable cooling/baking rack has first and second end frames, each of which includes a pair of laterally spaced posts. The rack also has a plurality of generally rectangular shelving elements which are generally horizontally disposed and which are connected to the end frames. The shelving elements and end frames are movable between an upright, operable position and a folded, inoperable position. In the upright positions, the shelving elements are disposed generally perpendicularly to the end frames, while in the folded, inoperable position, the shelving elements and end frames are disposed in a generally non-perpendicular relationship. In one embodiment, the shelving elements are detachably connected to the second end frame, and are pivotably, but non-detachably, connected to the first end frame. A number of alternative joints, including T-shaped and L-shaped joints, are suggested for the pivotal connection between the sheliving elements and the first end frame. Likewise, a number of alternative embodiments for the detachable connection between the shelving units and second end frame are also provided.
