Abstract
Abstract ABSTRACT OF THE DISCLOSURE CHAIR A stacking chair having a unitary tubular frame supporting seat and back panels. The frame is formed in one piece from circular section tubing and defines a pair of closed loops at opposite sides of the chair forming the legs and two cross members behind the back panel. The back panel is rolled over the tubular frame at the top and sides and defines hand grip openings at the top corners and in the centre region of the back just below the lower cross member. The seat is made of a peripheral frame covered by a sheet steel member which is rolled over the frame except at the sides where the sheet member overhangs the chair frame and is secured thereto.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
156 words
A chair comprising a seat panel, a back panel and a unitary tubular frame supporting said panels, the frame being shaped to define a pair of closed loops at opposite sides of the chair, each including a pair of generally upright limbs forming front and rear legs, and top and bottom limbs extending between upper and lower ends of the respective upright limbs, said limbs forming the rear legs of the respective loops having portions which extend upwardly above said top limbs and to which said back panel is secured, the frame further including a first cross member joining said upwardly extending limb portions and a second cross member coupling said top limbs, said frame cross members comprising the only portions of the frame connecting the loops, said seat panel being supported on and secured to said top limbs of the respective loops and serving as a structural member maintaining the required spacing of said loops.
Claim 2
Dependent Claim
156 words
A chair comprising a seat panel, a back panel and a unitary tubular frame supporting said panels, the frame being shaped to define a pair of closed loops at opposite sides of the chair, each including a pair of generally upright limbs forming front and rear legs, and top and bottom limbs extending between upper and lower ends of the respective upright limbs, said limbs forming the rear legs of the respective loops having portions which extend upwardly above said top limbs and to which said back panel is secured, the frame further including a first cross member joining said upwardly extending limb portions and a second cross member coupling said top limbs, said frame cross members comprising the only portions of the frame connecting the loops, said seat panel being supported on and secured to said top limbs of the respective loops and serving as a structural member maintaining the required spacing of said loops.
Claim 3
Dependent Claim
50 words
A chair as claimed in claim 1, wherein said second cross member is disposed behind said back panel and couples said top limbs by way of intermediate frame portions exten-ding upwardly from the respective top limbs inwardly of and secured to said upwardly extending portions of the rear leg limbs.
Claim 4
Dependent Claim
52 words
A chair as claimed in claim 2, wherein said back panel defines an opening, for use in lifting the chair, said opening being disposed immediately below said second cross member and the panel being shaped so that said opening presents a smooth edge to the hand of a person lifting the chair.
Claim 5
Dependent Claim
78 words
A chair as claimed in claim 2, wherein said back panel overlies both of said first and second cross members, wherein at least said first cross member and said frame portions to which the back panel is secured are of circular shape in cross section, and where said back panel comprises a sheet form member marginal por-tions of which are rolled over said cylindrical frame portions whereby said marginal portions of the panel present a smooth external surface.
Claim 6
Dependent Claim
46 words
A chair as claimed in claim 4, wherein said back panel includes a central marginal portion which is rolled over said first cross member, and cut-outs at respectively opposite ends of said central portion through which portions of the chair frame are exposed, providing hand grips.
Claim 7
Dependent Claim
43 words
A chair as claimed in claim 1, wherein said loops of the frame are disposed in respective planes which are angled outwardly towards the bottom of the chair to an extent sufficient to permit the chair to be stacked with other similar chairs.

A chair as claimed in claim 6, further compri-sing respective arms each of a generally C-shaped confi-guration comprising a bottom limb, a top limb and a base, the bottom limbs of the respective arms being removably secured to lower surfaces of said top limbs of the frame with the bases of the arms at the rear of the chair and the top limbs projecting forwardly, the arms being arranged to permit stacking of the chair with other similar chairs, primarily from the front.
Claim 9
Dependent Claim
51 words
A chair as claimed in claim 7, wherein each said arm is formed from a generally tubular member the shape of which is distorted along at least the lower limb of the member to a profile designed to permit the arm to seat snugly on said top limb of the frame.

Dependent Claim
58 words
A chair as claimed in claim 8, wherein said top limb of each arm includes a flattened outer portion which is folded back on itself to define respective upper and lower superposed flattened parts, and wherein the arm is provided with an arm rest comprising a cover on said upper part trapped between said upper and lower parts.
Claim 11
Dependent Claim
63 words
A chair as claimed in claim 1, wherein said seat comprises a peripheral frame of circular cross-section and a panel of sheet material secured to said frame with marginal portions of the sheet rolled over the frame to present a smooth external profile and portions of said sheet overhanging the frame at opposite sides of the seat and secured to the chair frame.
Claim 12
Dependent Claim
44 words
A chair as claimed in claim 1, having at least one arm coupled to said frame and a tablet pivotally coupled to said arm for movement between a generally horizontal position in which the tablet defines a work surface, and a raised inoperative position.
Claim 13
Dependent Claim
23 words
A chair as claimed in claim 1 in combination with wire frame basket releasably coupled to said chair and disposed below the seat.
