Hoop chair

A chair comprising:

• a metal circular cross-section frame component substantially defining the periphery of a chair seat or back;
• upholstery means, said upholstery means having a body portion forming a seat or back of the chair, and including a welt formed around substantially the periphery of said body portion;
• clamping means for cooperating with said frame component for holding said upholstery means so that said upholstery means body remains in place defining an operative chair seat or back portion, said clamping means consisting of a clamping component having a peripheral configuration cooperating with said frame component to operatively hold said upholstery means therebetween;
• said clamping component comprising an inner ring having a substantially half-circular concave peripheral cross-section so that said clamping component and said frame component clamp said upholstery means therebetween so that said welt is disposed on the opposite side of said ring and said frame from said body of said upholstery means;
• and
• means for supporting said frame component off the ground.

A chair comprising:

• a frame component substantially defining the periphery of a chair seat or back and comprising a metal circular cross-section tubular hoop having a pair of adjacent open end portions;
• upholstery means, said upholstery means having a body portion forming a seat or back of the chair, and including a welt formed around substantially the periphery of said body portion;
• clamping means for cooperating with said frame component for holding said upholstery means welt so that said upholstery means body remains in place defining an operative chair seat or back portion, said clamping means including a clamping component having a peripheral configuration cooperating with said frame component to operatively hold said upholstery means therebetween;
• means for supporting said frame component off the ground;
• and
• means for adjusting the seat or back portion area defined by the periphery of said hoop, comprising internal threading formed in said frame hoop at said open end portions, the threading in one open end portion being left-handed and the threading in the other open end portion being right-handed;
• a connector connecting said open end portion, said connector comprising a central rotatable body portion, and a pair of shaft portions extending outwardly from opposite sides of said body portion, one of said shaft portions being threaded for cooperation with said hoop open end left-handed internal threads, and the other of shaft portions having external threading for cooperating with said hoop open end right-handed internal threads.

A chair comprising:

• a generally circular cross-section frame component defining substantially the periphery of a chair seat and back;
• upholstery means forming the seat and back of said chair, including a body defining the chair seat and back, and a welt formed around substantially the entire periphery of said body;
• clamping means for clamping said upholstery means body to said frame component so that said welt is disposed on the opposite side of said frame component from said seat and back, said clamping means consisting of a clamping component having a peripheral configuration corresponding to the peripheral configuration of said frame component;
• said clamping component comprising an inner ring having a substantially half-circular concave peripheral cross-section so that said clamping component and said frame component clamp said upholstery means therebetween so that said welt is disposed on the opposite side of said ring and said frame from said body of said upholstery means;
• and
• means for supporting said frame component off the ground.
