Abstract

A folding chair construction comprising a plurality of substantially U-shaped portions, each having a pair of parallel side sections connected by a right angle corner member to a medial section, providing back and seat portions and front and rear legs hingedly connected for movement between a folded position, wherein all of the U-shaped portions are superposed with one another, and an erected position, wherein the U-shaped portions are relatively angularly disposed. The side sections of the back and seat portions and the medial sections of all portions are formed of tubular members connected for relative, telescoping movement between extended and retracted positions when the chair is in the unfolded and folded positions, respectively. A flexible fabric support portion is permanently secured to the back and seat portions by outwardly extending portions of the fabric which are looped around the side and medial sections and stitched to themselves. The width of the outwardly extending portions is not substantially greater than the lengths of the side and medial sections about which they are looped when such sections are in their retracted positions.

A folding chair construction comprising, in combination:

(a) a back portion of essentially U-shaped configuration including a pair of parallel, first side sections, each connected at one end to opposite ends of a first medial section and extending therefrom to free ends;
(b) a seat portion of essentially U-shaped configuration including a pair of parallel, second side sections each connected at one end to opposite ends of a second medial section and extending therefrom to free ends;
(c) first hinge means connecting said back and seat portions adjacent said free ends of each of said first and second side sections for pivotal movement between relatively folded and erected positions wherein said back and seat portions are in superposed and angularly disposed relation, respectively;
(d) front leg means of essentially U-shaped configuration including a pair of parallel, third side sections, each connected at one end to opposite ends of a third medial section and extending therfrom to free ends;
(e) rear leg means of essentially U-shaped configuration including a pair of parallel, fourth side sections, each connected at one end to opposite ends of a fourth medial section and extending therefrom to free ends;
(f) second hinge means connecting said front leg means and said seat portion adjacent said one ends of said second side sections and said free ends of said third side sections for pivotal movement between respective fold and erected positions wherein said front leg means and said seat portion are in supoerposed and angularly disposed relation, respectively;
(g) third hinge means connecting said rear leg means and said seat portion adjacent said free ends of each of said second and fourth side sections for pivotal movement between respective folded and erected positions wherein said front and rear leg means are in supoerposed relation and said rear leg means and said seat portion are in angularly disposed relation, respectively;
(h) each of said first and second side sections and said first, second, third and fourth medial sections comprising a plurality of tubular members connected in end-to-end relation for axial, telescoping movement between mutually extended and retracted positions;
and
(i) a unitary support portion of flexible material secured to said first side and medial portions and said second side and medial portions to extend laterally between both of said first and second side sections and longitudinally between said first and second medial sections when said back and seat portions are in said erected position, and said tubular members are in said mutually extended positions.
