Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A collapsible framework comprising a plurality of spars pivotally connected with hub members, and with one another to form a two-dimensionally expanding linkage, and at least one upright brace, detachably connectable between at least one said hub member and an adjoining said hub member above it, to brace the linkage in an expanded condition and wherein said upright brace comprises a plurality of rigid lengths detachably connected end-to-end by plug and socket connections and by resilient tensioning means which serve to draw adjacent lengths into interfitting relationship when said lengths are aligned.
Claim 2
Dependent Claim
92 words
A collapsible framework comprising a plurality of spars pivotally connected with hub members, and with one another to form a two-dimensionally expanding linkage, and at least one upright brace, detachably connectable between at least one said hub member and an adjoining said hub member above it, to brace the linkage in an expanded condition and wherein said upright brace comprises a plurality of rigid lengths detachably connected end-to-end by plug and socket connections and by resilient tensioning means which serve to draw adjacent lengths into interfitting relationship when said lengths are aligned.
Claim 3
Dependent Claim
32 words
A collapsible framework according to claim 1 wherein said upright brace is of iron or steel whereby a cladding sheet having magnetic securing means thereon, can readily be attached to said brace.
Claim 4
Dependent Claim
170 words
A collapsible framework comprising a plurality of spars pivotally connected with hub members, and with one another to form a two-dimensionally expanding linkage, and at least one upright brace, detachably connectable between at least one said hub member and an adjoining said hub member above it, to brace the linkage in an expanded condition and wherein said hub members include first hub members which lie on a notional first surface of the erected framework and second hub members which lie on a notional second surface of the erected framework generally parallel with, and spaced from said first surface, each said first hub member being connected, via the spars extending therefrom, with respective said second hub members, and conversely, each said first hub member being directly opposed by a respective said second hub member the spars of which are pivotally connected with the spars of the opposing first hub member, and each said first hub member being connected with the opposing said second hub member by a resiliently extensible tensioning element.
Claim 5
Dependent Claim
170 words
A collapsible framework comprising a plurality of spars pivotally connected with hub members, and with one another to form a two-dimensionally expanding linkage, and at least one upright brace, detachably connectable between at least one said hub member and an adjoining said hub member above it, to brace the linkage in an expanded condition and wherein said hub members include first hub members which lie on a notional first surface of the erected framework and second hub members which lie on a notional second surface of the erected framework generally parallel with, and spaced from said first surface, each said first hub member being connected, via the spars extending therefrom, with respective said second hub members, and conversely, each said first hub member being directly opposed by a respective said second hub member the spars of which are pivotally connected with the spars of the opposing first hub member, and each said first hub member being connected with the opposing said second hub member by a resiliently extensible tensioning element.
Claim 6
Dependent Claim
33 words
A collapsible framework according to claim 3 wherein said upright brace is of iron or steel whereby by a cladding sheet having magnetic securing means thereon can readily be attached to said brace.
