Abstract
The three-legged folding chair has a primary frame with two legs and an apex, a secondary frame with two arms and an apex, and a third leg. The secondary frame is pivotally attached to the primary frame by two pivot pins. A back rest is secured to the primary frame adjacent to the primary frame apex. A support seat is attached to the arms of the secondary frame and are spaced from the secondary frame apex. The third leg is connected to the backrest adjacent to the primary frame apex. The apex of the secondary frame is held in a use position by the third leg. The secondary frame intersects the primary frame at an angle of about 66.degree. when held by the third leg. Both pivot pins are held out of axial alignment with each other when in the use position. The ground contact ends of the primary frame legs are under the forward edge of the support seat, the third leg is relatively short and weight is transferred to the third leg. The backrest is spaced forwardly from the primary frame apex.
