Abstract

A pivotable folding utility table includes a table top having a pair of support pedestals pivotally attached thereto. A first pivotal support brace including a distal end and a proximal end attached to the first support pedestal. A second pivotal support brace including a distal end and a proximal end attached to the second support pedestal. The distal ends of the first and second pivotal support braces pivotally attached to a retaining assembly preferably mounted in relation to the table top. Specifically, the retaining assembly includes a cross-brace member operably disposed through openings formed in the distal ends of the first and second pivotal support braces, thus providing a pivotal engagement in relation to the table top. Alternatively, a second retaining assembly including a cross-brace member may be mounted in relation to the table top, wherein the distal end of the first pivotal support brace pivotally engages the first retaining member and the distal end of the second pivotal support brace pivotally engages the second retaining member. In addition, the first and second support pedestals may comprise at least one support leg, wherein each support leg of the first and second support pedestals are laterally offset from each other so as to permit an offset displacement of the support legs when the support pedestals are disposed in a collapsed position.
