Abstract
Abstract A limited number of tubular frame sections of similar predetermined shape are provided. Frame sections can be secured together by way of inserts. The frame sections are shaped so that they can be manually assembled into various articles of furniture as for example a chair, an ottoman, or a table, the articles having suitable strength and rigidity and being foldable or collapsible into a compact condition. Various types of flexible material is attachable to the assembled frames to form seating material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
A set of similarly shaped joinable tubular frame sections, the frame sections having means at their ends whereby one section can be joined to another, whereby to form the frame of an article of furniture, said sections being of generally U configuration, the ends of first sections being joinable to ends of other sections with said other sections lying in planes generally transverse to planes of the first sections to form the frame of an article of furniture, having generally parallel upright portions and portions extending transversely between the upright portions, and means providing a supporting surface secured to said transversely extending portions, said upright portions comprising sections having a configuration providing three bends, iNcluding an intermediate bend and two bends between the intermediate bend and the end part of the sections, and flexible means comprising elongated elements having portions looped around said intermediate bends for holding the sections in joined relationship.
Claim 2
Dependent Claim
152 words
A set of similarly shaped joinable tubular frame sections, the frame sections having means at their ends whereby one section can be joined to another, whereby to form the frame of an article of furniture, said sections being of generally U configuration, the ends of first sections being joinable to ends of other sections with said other sections lying in planes generally transverse to planes of the first sections to form the frame of an article of furniture, having generally parallel upright portions and portions extending transversely between the upright portions, and means providing a supporting surface secured to said transversely extending portions, said upright portions comprising sections having a configuration providing three bends, iNcluding an intermediate bend and two bends between the intermediate bend and the end part of the sections, and flexible means comprising elongated elements having portions looped around said intermediate bends for holding the sections in joined relationship.
Claim 3
Dependent Claim
154 words
A set of similarly shaped joinable tubular frame sections, the frame sections having means at their ends whereby one section can be joined to another, whereby to form the frame of an article of furniture, said sections being of generally U configuration, the ends of the first sections being joinable to ends of other sections with said other sections lying in planes generally transverse to planes of the first sections to form the frame of an article of furniture, having generally parallel upright portions and portions extending transversely between the upright portions and means providing a supporting surface secured to said transversely extending portions, flexible supporting means secured to said transversely extending portions, and flexible seat material secured to and supported by said flexible means, said flexible means comprising straps having parts attached to the supporting surface in a manner to urge the joined sections together to hold the article rigidly assembled under compression.
Claim 4
Dependent Claim
154 words
A set of similarly shaped joinable tubular frame sections, the frame sections having means at their ends whereby one section can be joined to another, whereby to form the frame of an article of furniture, said sections being of generally U configuration, the ends of the first sections being joinable to ends of other sections with said other sections lying in planes generally transverse to planes of the first sections to form the frame of an article of furniture, having generally parallel upright portions and portions extending transversely between the upright portions and means providing a supporting surface secured to said transversely extending portions, flexible supporting means secured to said transversely extending portions, and flexible seat material secured to and supported by said flexible means, said flexible means comprising straps having parts attached to the supporting surface in a manner to urge the joined sections together to hold the article rigidly assembled under compression.
Claim 5
Dependent Claim
41 words
Apparatus as in claim 2, wherein the sections include a rear section to form the back of a chair, said flexible means comprising a strap attached to the supporting surface and passing in back of the rear section of the chair.
Claim 6
Dependent Claim
23 words
Apparatus as in claim 3, wherein said flexible means comprises a strap attached to the supporting surface and passing underneath said upright portions.
Claim 7
Dependent Claim
14 words
Apparatus as in claim 1, wherein said supporting surface comprises a rigid table top.
Claim 8
Dependent Claim
24 words
Apparatus as in claim 2, said strap means having parts engaging said generally parallel upright portions and parts secured to said flexible seat material.
Claim 9
Dependent Claim
