Abstract
Abstract In articles formed from at least two boards in each of two planes and joined by plugs fitted into spaced holes formed in the faces of the boards in one plane and aligned holes in the ends of the boards of the other plane, the boards in each plane are of different width and arranged so that the adjacent edges of the boards in one plane are covered by a board in the other plane. The narrower boards are provided with at least two holes and the wider boards with at least three holes across their width, the spacing of all the holes being equal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
Boards connected at an angle, preferably a right-angle, to each other and of which boards at least one is provided with spaced holes on a line across its face and at least one other board is provided in a planar edge with holes aligned with the holes of the first-mentioned board, and connecting pins being frictionally held in the holes of said boards, characterised in that in the planes defined by the boards at an angle to at least one of the other boards of different width and substantially the same total width are arranged so that the boards in one plane cover the gap between the boards in the other plane, the narrower boards being provided with at least two holes and the wider boards being provided with at least three holes and the spacing of the holes in all of the boards being equal and the spacing (a) of the outer holes from the nearest board edges in lines drawn through the holes being less than half the spacing of the holes from each other.
Claim 2
Dependent Claim
177 words
Boards connected at an angle, preferably a right-angle, to each other and of which boards at least one is provided with spaced holes on a line across its face and at least one other board is provided in a planar edge with holes aligned with the holes of the first-mentioned board, and connecting pins being frictionally held in the holes of said boards, characterised in that in the planes defined by the boards at an angle to at least one of the other boards of different width and substantially the same total width are arranged so that the boards in one plane cover the gap between the boards in the other plane, the narrower boards being provided with at least two holes and the wider boards being provided with at least three holes and the spacing of the holes in all of the boards being equal and the spacing (a) of the outer holes from the nearest board edges in lines drawn through the holes being less than half the spacing of the holes from each other.
Claim 3
Dependent Claim
51 words
Boards according to claim 1, characterised in that in each plane defined by the boards extending at an angle to at least one of the other boards there is at least one narrower board and one wider board, the wider boards covering the gap between the boards in the other plane.
Claim 4
Dependent Claim
35 words
Boards according to claim 1, characterised in that only narrow boards or only wide boards are arranged in at least one of the planes defined by the boards extending at an angle to each other.
Claim 5
Dependent Claim
20 words
Boards according to claim 1, characterised in that the boards in one plane are replaced by a single wider board.
Claim 6
Dependent Claim
50 words
Boards according to claim 1, characterised in that the holes passing through the faces of the boards are provided with connecting pins projecting from both sides of the holes and the boards having holes in their ends are placed over said connecting pins on both sides of the provided therewith.
Claim 7
Dependent Claim
20 words
Boards according to claim 1, characterised in that the boards are of pine or spruce and the pins of beech.
Claim 8
Dependent Claim
18 words
Boards according to claim 1, characterised in that the boards consist of laths of plastics or sheet metal.
Claim 9
Dependent Claim
15 words
Boards according to claim 1, characterised in that the pins are of metal or platics.
