Application December 18, 1946,-Serial No. 716,900 1 Claim. (01. 155-136) This invention relates to an improvement in a foldin stool, and specifically contemplates providing a supporting frame which may be easily and quickly folded into a comparatively of their respective ends but are limited in the distance which they may be spread apart by stops which are an integral part of said body member. These latter frame members constitute the legs small, compact unit. 5 of said structure which engage the means upon Although there are numerous varieties of foldwhich 1saiddfolding stool supporting structure is ing stools in existence, the improvement in the 0 e p 1168 supporting structure of the folding type stool Referring to the drawings: proposed in this invention will substantially Figure 1 is an oblique view of the distended reducef bioth the time and expense required in supporting structure for a folding stool incormanu ac uring the said supporting structure porating one embodiment of this invention. for folding stools of a ty e presently in use.

The openings [1, l8 and [9 are provided in the leaves H, l2 and I3, respectively, for the reception of suitable pins, one of which is indicated at 20 in Figures 1 and 3, upon which said arms and legs are operably mounted for pivotal motion therearound. As shownlin Figures. 1 and: 3, the: arm 2 and the leg.5 are pivotally mounted on the same pin 20, through the opening I9 in the leave 1 and 3 that the arms are=swiveledadiaeent t'o the inner surfaces of the leaves H, I2. and lit whereas the legs are swiveled adjacent to the outer surfaces of said leaves.
