Abstract
Abstract An article combined with other parts which assemble into an item of furniture, the article constituting a spacer of extruded aluminum having a cylindrical bore therethrough and, as seen in cross-section, grooves outboard of such bore which are right angles to each other. Bores of aligned spacers receive posts and outboard legs therein define grooves which receive vertical panels with horizontal members between spacers, such horizontal members having openings which are aligned with the bores to receive vertical pipe. The vertical pipe thereby aligns the spacers, horizontal members and indirectly the vertical members. In one embodiment, L-shaped portions formed in the extruded spaces opposite the legs define further grooves which permit the use of connecting clips between adjacent shelves. Additional spacers having further grooves to provide midway and central aligned supports for larger shelves are also disclosed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
278 words
A spacer for supporting a horizontal platform which comprises an upright member having a uniform cross-section throughout its length, said member defining a groove for receiving a vertical panel and an opening spaced from said groove, said opening adapted to receive a vertical post for connecting a plurality of like spacers with horizontal platforms having aligned openings receiving said vertical post, said groove defined by two planar parallel longer sides and a shorter interior end so that as seen in cross-section each side is longer than their distance apart, planes coninciding with said sides being parallel to and spaced outwardly of said opening so that they are spaced outboard of and parallel to planes tangent to said opening, and a plane generally coinciding with said interior end throughout its length projecting through about the centerline of said opening, said member defining a further like groove which is adapted to receive a further vertical panel disposed at right angles to said first mentioned vertical panel on the other side of said opening, said grooves as seen in cross-section each having uniform depths defined by said interior ends, lines connecting said interior ends of said grooves to each other and to the centerline of said opening forming substantially a right triangle with the two shorter sides of said right triangle being equal in length, said member having a plane of symmetry which contains said centerline, the outer sides of said member which define in part its periphery coinciding in part, as seen in cross-section, with the sides of a square and said plane of symmetry coinciding with the diagonal of said square, said opening being circular as seen in cross-section.
Claim 2
Dependent Claim
278 words
A spacer for supporting a horizontal platform which comprises an upright member having a uniform cross-section throughout its length, said member defining a groove for receiving a vertical panel and an opening spaced from said groove, said opening adapted to receive a vertical post for connecting a plurality of like spacers with horizontal platforms having aligned openings receiving said vertical post, said groove defined by two planar parallel longer sides and a shorter interior end so that as seen in cross-section each side is longer than their distance apart, planes coninciding with said sides being parallel to and spaced outwardly of said opening so that they are spaced outboard of and parallel to planes tangent to said opening, and a plane generally coinciding with said interior end throughout its length projecting through about the centerline of said opening, said member defining a further like groove which is adapted to receive a further vertical panel disposed at right angles to said first mentioned vertical panel on the other side of said opening, said grooves as seen in cross-section each having uniform depths defined by said interior ends, lines connecting said interior ends of said grooves to each other and to the centerline of said opening forming substantially a right triangle with the two shorter sides of said right triangle being equal in length, said member having a plane of symmetry which contains said centerline, the outer sides of said member which define in part its periphery coinciding in part, as seen in cross-section, with the sides of a square and said plane of symmetry coinciding with the diagonal of said square, said opening being circular as seen in cross-section.
Claim 3
Dependent Claim
13 words
A spacer in accordance with claim 1, wherein said opening has a gap.
Claim 4
Dependent Claim
20 words
A spacer in accordance with claim 2, wherein said gap occupies an arc of about 50° centered from said centerline.
Claim 5
Dependent Claim
306 words
A spacer for supporting a horizontal platform which comprises an upright member having a uniform cross-section throughout its length, said member defining a groove for receiving a vertical panel and an opening spaced from said groove, said opening adapted to receive a vertical post for connecting a plurality of like spacers with horizontal platforms having aligned openings receiving said vertical post, said groove defined by two planar parallel longer sides and a shorter interior end so that as seen in cross-section each side is longer than their distance apart, planes coinciding with said sides being parallel to and spaced outwardly of said opening so that they are spaced outboard of and parallel to planes tangent to said opening, and a plane generally coinciding with said interior end throughout its length projecting through about the centerline of said opening, said member defining a further like groove which is adapted to receive a further vertical panel disposed at right angles to said first mentioned vertical panel on the other side of said opening, said grooves as seen in cross-section each having uniform depths defined by said interior ends, lines connecting said interior ends of said grooves to each other and to the centerline of said opening forming substantially a right triangle with the two shorter sides of said right triangle being equal in length, said member having a plane of symmetry which contains said centerline, the outer sides of said member which define in part its periphery coinciding in part, as seen in cross-section, with the sides of a square and said plane of symmetry coinciding with the diagonal of said square, said member defining a pair of additional grooves for receiving connecting clips adjacent said first-mentioned groove and said further groove, said additional grooves facing said opening and being inclined substantially 45° to said plane of symmetry.
Claim 6
Dependent Claim
306 words
A spacer for supporting a horizontal platform which comprises an upright member having a uniform cross-section throughout its length, said member defining a groove for receiving a vertical panel and an opening spaced from said groove, said opening adapted to receive a vertical post for connecting a plurality of like spacers with horizontal platforms having aligned openings receiving said vertical post, said groove defined by two planar parallel longer sides and a shorter interior end so that as seen in cross-section each side is longer than their distance apart, planes coinciding with said sides being parallel to and spaced outwardly of said opening so that they are spaced outboard of and parallel to planes tangent to said opening, and a plane generally coinciding with said interior end throughout its length projecting through about the centerline of said opening, said member defining a further like groove which is adapted to receive a further vertical panel disposed at right angles to said first mentioned vertical panel on the other side of said opening, said grooves as seen in cross-section each having uniform depths defined by said interior ends, lines connecting said interior ends of said grooves to each other and to the centerline of said opening forming substantially a right triangle with the two shorter sides of said right triangle being equal in length, said member having a plane of symmetry which contains said centerline, the outer sides of said member which define in part its periphery coinciding in part, as seen in cross-section, with the sides of a square and said plane of symmetry coinciding with the diagonal of said square, said member defining a pair of additional grooves for receiving connecting clips adjacent said first-mentioned groove and said further groove, said additional grooves facing said opening and being inclined substantially 45° to said plane of symmetry.
Claim 7
Dependent Claim
13 words
A spacer in accordance with claim 4, wherein said member comprises an extrusion.
Claim 8
Dependent Claim
14 words
A spacer in accordance with claim 5, wherein said member is composed of aluminum.
