ABSTRACT:
A chair which is usable as an ordinary seat, as a stadium seat, or as a beach seat comprises a generally quadralateral seat element having rigid side membes. A back support is pivotally secured to a rear end of the seat element to permit the back element to be moved from a collapsed position overlying the top of the seat to a support position extending upwardly in an inclined direction relative to the seat. A pair of arm elements are pivotally secured to the side frames of the seat and are pivotally movable between a position overlying the top of the seat and an upstanding position wherein the arm rests are disposed vertically above each side of the seat. Leg frames are provided having a generally inverted U-shaped configuration with the bight portion of the U-shape pivotally secured respectively to the side frames of the seat. The leg frames are pivotally movable from a position underlying the bottom portion of the seat to a position depending generally vertically downwardly from the seat. Additional features include a clamp element engagable with a stadium seat or a park bench to secure the seat frame in a fixed position relative to such support, and anti-tipping rods to provide support of the seat when the seat is used as a beach chair. The entire construction can be folded into a compact, generally rectangular package which can be readily inserted in a suitable carrying case.
