Abstract
Abstract A shapeable matrix comprises a plurality of first members (11) each of which has a plurality of projections (13) located on the periphery thereof, and a plurality of second members (1, 2, 3) each of which has a plurality of recesses (8, 10) located on the periphery thereof, each recess (8,10) being adapted to receive a respective one of the projections (13) of an adjacent first member (11). Means (7) are provided on each of the second members (1, 2, 3) for releasably clamping the projections (13) of the first members (11) in recesses (8, 10) of the second members (1, 2, 3) the clamping being operative in a released condition to permit alteration in the relative orientation of adjacent members and being operative in a clamped condition to prevent such alteration. A chair is disclosed which comprises a support frame (22) and a shapeable matrix (18) as set forth above mounted on the support frame (22).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A shapeable matrix comprising a plurality of first members each of which has a plurality of projections located on the periphery thereof, and a plurality of second members each of which has a plurality of recesses located on the periphery thereof, each recess being adapted to receive a respective one of the projections of an adjacent first member, and means provided on each of the second members for releasably clamping the projections of the first members in recesses of the second members, the clamping being operative in a released condition to permit alteration in the relative orientation of adjacent members and being operative in a clamped condition to prevent such alteration.
Claim 2
Dependent Claim
111 words
A shapeable matrix comprising a plurality of first members each of which has a plurality of projections located on the periphery thereof, and a plurality of second members each of which has a plurality of recesses located on the periphery thereof, each recess being adapted to receive a respective one of the projections of an adjacent first member, and means provided on each of the second members for releasably clamping the projections of the first members in recesses of the second members, the clamping being operative in a released condition to permit alteration in the relative orientation of adjacent members and being operative in a clamped condition to prevent such alteration.
Claim 3
Dependent Claim
30 words
A matrix according to claim 1, wherein each said first member comprises a central portion and a plurality of substantially spherical projections extending from the periphery of the central portion.
Claim 4
Dependent Claim
48 words
A matrix according to claim 1 or 2, wherein each said second member comprises a pair of plastic discs with a metal plate sandwiched between them, the discs and plate each having a plurality of openings in the periphery thereof which together define the said plurality of recesses.
Claim 5
Dependent Claim
52 words
A matrix according to claim 3, further comprising a pair of metal discs each sandwiched between the said metal plate and a respective one of the plastic discs, the said metal discs having serrated edges and being of such a size the serrated edges engage the said projections of the first member.
Claim 6
Dependent Claim
33 words
A matrix according to any preceding claim, wherein each first member has four projections arranged at 90° to one another, and each second member has four recesses arranged at 90° to one another.
Claim 7
Dependent Claim
37 words
A matrix according to any one of claims 1 to 4, wherein each first member has three projections arranged at 120° to one another, and each second projection has three recesses arranged at 120° to one another.
Claim 8
Dependent Claim
126 words
A chair which comprises a support frame; and a shapeable matrix mounted on the frame, the shapeable matrix comprising a plurality of first members each of which has a plurality of projections located on the periphery thereof, and a plurality of second members each of which has a plurality of recesses located on the periphery thereof, each recess being adapted to receive a respective one of the projections of an adjacent first member, and means provided on each of the second members for releasably clamping the projections of the first members in recesses of the second members, the clamping being operative in a released condition to permit alteration in the relative orientation of adjacent members and being operative in a clamped condition to prevent such alteration.
Claim 9
Dependent Claim
126 words
A chair which comprises a support frame; and a shapeable matrix mounted on the frame, the shapeable matrix comprising a plurality of first members each of which has a plurality of projections located on the periphery thereof, and a plurality of second members each of which has a plurality of recesses located on the periphery thereof, each recess being adapted to receive a respective one of the projections of an adjacent first member, and means provided on each of the second members for releasably clamping the projections of the first members in recesses of the second members, the clamping being operative in a released condition to permit alteration in the relative orientation of adjacent members and being operative in a clamped condition to prevent such alteration.
