Abstract

Abstract A collapsible beach chair which is formed from a covering, such as canvas, which is folded and joined together to define a pair of seat compartments and a pair of back compartments with the compartments being joined together by a transverse hinge portion of the covering. The seat compartments are joined together by a longitudinal hinge portion of the covering separate and apart from a longitudinal hinge portion of the covering joining together the back compartments. Each compartment has therein a stiffening element which includes a rigid backing having a padded surface. The hinge portions of the covering are so arranged that the seat may be folded with all four compartments being disposed in side-by-side relationship and with the back forming compartments disposed outermost. The back forming compartments are joined together by releasable strap means and carry handles to facilitate the carrying thereof. If desired, suitable strap means may be provided for tying together the handles and there may be a shoulder carrying strap. There are further strap means between the seat compartments and the back compartments for maintaining the back compartments at selected upstanding positions relative to the seat portion.

Claim 1
Independent Claim 408 words
A collapsible beach chair comprising: a flexible covering defining a front side and a rear side of said chair, said covering having portions joined together to define four compartments including first and second generally rectangular seat compartments and first and second generally rectangular back compartments separated by integral hinge-defining portions of said covering, wherein said first and second seat compartments are in substantial longitudinal alignment with said first and second back compartments, respectively, said hinge-defining portions comprising means for facilitating folding of said chair to a compact collapsed stack of said four compartments in side-by-side relation; four compartment stiffening members disposed in said four compartments, respectively, each stiffening member comprising a rigid rectangular member having at least one padded surface facing the front side of said chair; wherein said hinge-defining portions include a transverse hinge portion extending between seat compartment and said back compartments, a longitudinal back hinge portion extending between said first and second back compartments, and a longitudinal seat hinge portion extending between said first and second seat compartments; an integral back support strap extending transversely through said first and second back compartments and having first and second free ends extending out from first and second mutually remote longitudinal edges of said first and second back compartments, respectively, wherein said back support strap is bonded to said covering inside each of said first and second back compartments at locations between the stiffening members and the rear side of the chair; an integral seat support strap extending transversely through said first and second seat compartments and having first and second free ends extending out from first and second mutually remote longitudinal edges of said first and second seat compartments, respectively, wherein said seat support strap is bonded to said covering inside each of said first and second seat compartments at locations between the stiffening members and the rear side of the chair; first engagement means for releasably securing the first ends of said back support strap and said seat support strap directly together to provide an adjustable length engagement between the first longitudinal edge of said first back compartment and the first longitudinal edge of said first seat compartment; and second engagement means for releasably securing the second ends of said back support strap and said seat support strap directly together to provide an adjustable length engagement between said second longitudinal edge of said second back compartment and said second longitudinal edge of said second seat compartment.
Claim 2
Dependent Claim 408 words
A collapsible beach chair comprising: a flexible covering defining a front side and a rear side of said chair, said covering having portions joined together to define four compartments including first and second generally rectangular seat compartments and first and second generally rectangular back compartments separated by integral hinge-defining portions of said covering, wherein said first and second seat compartments are in substantial longitudinal alignment with said first and second back compartments, respectively, said hinge-defining portions comprising means for facilitating folding of said chair to a compact collapsed stack of said four compartments in side-by-side relation; four compartment stiffening members disposed in said four compartments, respectively, each stiffening member comprising a rigid rectangular member having at least one padded surface facing the front side of said chair; wherein said hinge-defining portions include a transverse hinge portion extending between seat compartment and said back compartments, a longitudinal back hinge portion extending between said first and second back compartments, and a longitudinal seat hinge portion extending between said first and second seat compartments; an integral back support strap extending transversely through said first and second back compartments and having first and second free ends extending out from first and second mutually remote longitudinal edges of said first and second back compartments, respectively, wherein said back support strap is bonded to said covering inside each of said first and second back compartments at locations between the stiffening members and the rear side of the chair; an integral seat support strap extending transversely through said first and second seat compartments and having first and second free ends extending out from first and second mutually remote longitudinal edges of said first and second seat compartments, respectively, wherein said seat support strap is bonded to said covering inside each of said first and second seat compartments at locations between the stiffening members and the rear side of the chair; first engagement means for releasably securing the first ends of said back support strap and said seat support strap directly together to provide an adjustable length engagement between the first longitudinal edge of said first back compartment and the first longitudinal edge of said first seat compartment; and second engagement means for releasably securing the second ends of said back support strap and said seat support strap directly together to provide an adjustable length engagement between said second longitudinal edge of said second back compartment and said second longitudinal edge of said second seat compartment.
Claim 3
Dependent Claim 50 words
The collapsible beach chair according to claim 1 wherein said flexible covering is canvas and sewn together at seams to define said compartments, and wherein said back support strap and said seat support strap are bonded to said covering by stitched seams extending along the respective lengths of the straps.
Claim 4
Dependent Claim 68 words
A chair according to claim 1 wherein said longitudinal back hinge portion is relatively narrow to permit said first and second back compartments to be folded in side-by-side facing relation, and wherein said longitudinal seat hinge portion is relatively wide to permit said first and second compartments to be folded in spaced apart side-by-side facing relation to one another with said first and second back compartments positioned therebetween.
Claim 5
Dependent Claim 35 words
The chair according to claim 1 further comprising cooperating strap means extending from said first and second mutually remote longitudinal edges of said seat compartments for releasably holding the four compartments in said folded relation.
Claim 6
Dependent Claim 38 words
The chair according to claim 1 further comprising first and second handles secured to said first and second mutually remote longitudinal edges of said seat compartments, and positioned adjacent one another in the folded relation of said compartments.
Claim 7
Dependent Claim 30 words
