Plastic washtub leg

Claim 1

A plastic leg for a washtub comprising a substantially flat and rigid elongated plastic preform, said preform including a pair of elongated spaced apart grooves formed therein and extending throughout substantially the entire length thereof, said grooves dividing said preform into three substantially parallel elongated sections and forming living hinges so that said preform can be folded into a substantially prism shape having a triangular cross section, and means for maintaining said preform in its folded condition including a plurality of apertures formed in said plastic preform along one edge thereof and a plurality of cooperating tabs extending from said preform along the opposite edge thereof, said tabs extending through said apertures when said preform is folded into its prism shape so that the free ends of said tabs are accessible from the exterior of said leg, each of said tabs including a shoulder portion which is adapted to fit over the upper surface of said apertures on the exterior of said leg to prevent said tabs from being withdrawn from the apertures after they pass therethrough, said shoulder portions extending in directions substantially perpendicular to the axes of said apertures, some of said shoulder portions extending in a direction different from the remaining shoulder portions.
