ABSTRACT:
A folding stool comprising a pair of hinged seat supports (10) connected to a pair of hinged leg supports (22) by way of a pair of pivots (26) in such a manner that the leg supports fold up into and fit within the seat supports thus making a compact package convenient to carry and store. Hinged leg supports and hinged seat supports cross each other at the point of the pivots in substantially X form when stool is open and in use. The leg supports are connected to each other by means of a flexible double acting hing (24) permitting rotation of the leg supports over the 180.degree. horizontal and, moving in concert about the pivots, leg supports and seat supports are brought into a position suitable for supporting an adult user at a comfortable, normal chair height. The dimension representing seat height when stool is in use is substantially greater than the longest dimension of the folded package.
A readily detachable and foldable seat (14) stretches across the top of and engages the seat supports preventing further opening of the stool while also holding support members in controlled and firm adjustment when stool is in use and under stress. With stool folded, seat fits snugly between folded support members presenting a compact package convenient to carry and store.
