Abstract
Abstract A wall system comprises hollow framework structural members which can be assembled to form a hollow framework and subsequently disassembled, and transparent and opaque wall elements, the framework being intended to support the wall elements. The hollow framework structural member comprise vertical studs and horizontal battens. The invention is characterized in that each of the studs comprises a stud profile (5) and an end-piece the upper and the lower end of the stud profile; in that channels (7) are distributed peripherally around and along the profile; in that recesses are provided peripherally around the end-pieces; in that the channels (7) and the recesses are distributed uniformly and equidistantly around respective peripheries, the channels (7) and the recesses being at least eight in number and being intended to lie in register with one another; and in that one or more battens is, are, intended to be fitted into recesses of one and the same end-piece; and in that the vertical edge of a wall element supported by respective battens extends along respective channels (7) in the stud profile (5).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
214 words
A wall system including hollow framework structural members which can be assembled to form a hollow framework and subsequently disassembled, and transparent and opaque wall elements, said hollow framework being intended to support said wall elements, said structural members comprising studs or posts which are intended to extend vertically, and battens which are intended to be placed horizontally between the studs, characterised in that each of said studs includes a stud profile (5, 5') and an end-piece (6,6') at the upper and the lower ends respectively of the stud profile; in that the stud profile (5, 5') has channels (7) distributed around the periphery thereof and extending along the length thereof; in that the the end-pieces (6, 6') have recesses (8) distributed around the periphery thereof; in that the channels (7) and the recesses (8) are distributed uniformly and equidistantly around respective peripheries, said channels (7) and recesses (8) being at least eight in number and being intended to lie in register with one another; in that one or more battens (2, 3) are intended to be fitted into recesses (8) of one and the same end-piece (6, 6'); and in that the vertical edge of a wall element supported by respective battens extends along a corresponding channel (7) in the stud profile (5,5').
Claim 2
Dependent Claim
214 words
A wall system including hollow framework structural members which can be assembled to form a hollow framework and subsequently disassembled, and transparent and opaque wall elements, said hollow framework being intended to support said wall elements, said structural members comprising studs or posts which are intended to extend vertically, and battens which are intended to be placed horizontally between the studs, characterised in that each of said studs includes a stud profile (5, 5') and an end-piece (6,6') at the upper and the lower ends respectively of the stud profile; in that the stud profile (5, 5') has channels (7) distributed around the periphery thereof and extending along the length thereof; in that the the end-pieces (6, 6') have recesses (8) distributed around the periphery thereof; in that the channels (7) and the recesses (8) are distributed uniformly and equidistantly around respective peripheries, said channels (7) and recesses (8) being at least eight in number and being intended to lie in register with one another; in that one or more battens (2, 3) are intended to be fitted into recesses (8) of one and the same end-piece (6, 6'); and in that the vertical edge of a wall element supported by respective battens extends along a corresponding channel (7) in the stud profile (5,5').
Claim 3
Dependent Claim
44 words
A wall system according to claim 1, characterised in that said stud profile (5,5') in cross section has an equilateral, polygonal shape; in that said channel (7) is of U-shaped cross-section; and in that a channel is provided in each side of the polygon.
Claim 4
Dependent Claim
48 words
A wall system according to claim 1 characterised in that the system further includes profile strips (42) which are intended to co-act with those channels (7) of the stud profile (5, 5') which are located between the channel or channels (7) along which the wall element (4) extends.
Claim 5
Dependent Claim
73 words
A wall system according to claim 3, wherein the profile strips (42) have a cross-section which is a truncated triangle with equal base angles, the effective convergent angle (2 V) of which is equal to 360° divided by the number of channels (7) in the stud profile (5, 5'), and the truncated surface (43) of which has a width which corresponds to the width of one side of the stud profile (5, 5').
Claim 6
Dependent Claim
96 words
A wall system according to claim 1, characterised in that each end-piece (6, 6') has in cross-section a fully circular, or essentially a fully circular shape; in that said recesses (8) are substantially U-shaped, where each recess has a gape width (B1) which is smaller than the largest width (B2) of the recess (8); and in that the system also includes a fastener device (12) which comprises a substantially U-shaped part (13) which is intended to be fitted into the recess (8), one such fastener device being provided at each end of each batten (2, 3).
Claim 7
Dependent Claim
36 words
A wall system according to claim 1, characterised in that said battens (2, 3) are substantially of U-shaped cross-section, and in that the width of the U is adapted to the thickness of the wall element.
Claim 8
Dependent Claim
67 words
A wall system according to claim 3, wherein means adjacent each of the upper and lower ends of the stud profile, including said end pieces, said upper and lower ends of the stud profile and the adjacent ends of each said profile strip, structurally interlock said profile strips and said stud profile and maintain each said profile strip in its associated said channel in said stud profile.
