## Abstract

A truss designed folding Apparatus. The apparatus may be constructed of a first apparatus top section and a second apparatus top section which may be pivotally connected together by a center support structure. The apparatus may have two sets of legs. A first set of legs may be movably attached to the center support structure and a second set of legs may also be movably attached to the center support structure. Each set of legs may also be attached to the apparatus top via a first and a second leg support extending from the legs to the apparatus top sections. A shelf connection may be placed between the first and second leg support wherein, a shelf attached to each pair of legs the shelf may have a first section and second section, wherein the sections are attached to each other at opposite ends of the shelf connection.

## Claims
