ABSTRACT:
A tripod is elevated off the ground and supported by a three legged unit so that when opened it cradles the legs and/or the spreader of a tripod. The legs of the unit are hinged together along the spinal edge allowing the unit to fold close in a book-type manner. Attached to the unit is a platform leaf for the purpose of supporting a tripod operator. The platform leaf is supported by hinges attached to the top edge of one of the three legs and also by retractable folding legs. The retractable folding legs collapse to a position parallel to the platform leaf and the platform leaf collapses to a position parallel to the legs allowing the entire unit to be easily folded for compact transportation.
