Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
187 words
A demountable building comprising a roof and side walls, said side walls consisting essentially of an even number of panels in the shape of equilateral triangles having substantially identical dimensions, with said side wall panels leaning alternately inward and outward, and said roof comprising half as many panels as said side walls meeting at a common apex, each panel comprising a triangular frame and a sheet covering at least one side of said frame, said frames constituting the principal load-bearing support for the building, and said side wall panels being assembled alternately so that the base portion of at least two side wall panels lie in a horizontal plane along the bottom of said building with a third intermediate side wall panel nested therebetween having its base portion in a horizontal plane along the upper edge of the wall of said building, said three side wall panels being interlocked by interfitting means, said interfitting means comprising a plurality of mating surfaces which abut each other along the adjacent edges of adjacent panels whereby the weight of said intermediate panel gives a wedging effect between said mating surfaces.
Claim 2
Dependent Claim
187 words
A demountable building comprising a roof and side walls, said side walls consisting essentially of an even number of panels in the shape of equilateral triangles having substantially identical dimensions, with said side wall panels leaning alternately inward and outward, and said roof comprising half as many panels as said side walls meeting at a common apex, each panel comprising a triangular frame and a sheet covering at least one side of said frame, said frames constituting the principal load-bearing support for the building, and said side wall panels being assembled alternately so that the base portion of at least two side wall panels lie in a horizontal plane along the bottom of said building with a third intermediate side wall panel nested therebetween having its base portion in a horizontal plane along the upper edge of the wall of said building, said three side wall panels being interlocked by interfitting means, said interfitting means comprising a plurality of mating surfaces which abut each other along the adjacent edges of adjacent panels whereby the weight of said intermediate panel gives a wedging effect between said mating surfaces.
Claim 3
Dependent Claim
35 words
A building as claimed in claim 1 in which said interfitting means comprise connecting members positioned between the panels, the edges of said panels and said connecting members being formed with interfitting tongues and grooves.
Claim 4
Dependent Claim
29 words
A building as claimed in claim 1 in which the edges of said panels lie in planes making an angle of about 20* with the planes of said sheets.
Claim 5
Dependent Claim
24 words
A building as claimed in claim 3 in which said interfitting means comprise interfitting tongues and grooves formed in the edges of said panels.
Claim 6
Dependent Claim
36 words
A building as claimed in claim 1 consisting essentially of fifteen panels interconnected to form a structure having the shape of an icosahedron from which five sides having apices at a common point have been removed.
Claim 7
Dependent Claim
29 words
A demountable building as claimed in claim 1 in which said interfitting means are projections extending from the edges of the panels at an acute angle to said edges.
Claim 8
Dependent Claim
44 words
A demountable building as claimed in claim 6 in which said projections have surfaces mating with surfaces on adjacent panels and extending transversely with respect to a horizontal lIne lying in either the principal plane of its panel or in a plane perpendicular thereto.
Claim 9
Dependent Claim
68 words
A building as claimed in claim 1 in which at least some of said panels have a discrete first sheet covering one side of the panel frame and having its edges substantially flush with those of said frame, and a discrete second sheet covering the opposite side of said frame, at least one of the edges of said second sheet projecting beyond the edge of said first sheet.
Claim 10
Dependent Claim
15 words
A building as claimed in claim 1 having eight sidewall panels and four roofing panels.
