Claim 3

The combination as defined in claim 1 in which said tab is offset from said members so that one surface of said member and one surface of said tab are in substantial alignment with each other when said member and said tab are lying in parallel planes.

Claim 4

A combination as defined in claim 2 in which the member edge of said member and said tab is slanted from the hinge means to permit free hinge movement of said tab relative to said member in at least one direction.

Claim 5

A combination as defined in claim 3 in which the edges of said member and said tab are tapered so to permit said tab to be swung relative to said member in two directions.

Claim 6

A combination as defined in claim 4 in which said member edge forms a member corner on said member, and said tab edge forms a tab corner on said tab, and in which said tab and said member are so positioned that the corners meet, and in which said hinge means is formed adjacent the location where said corners meet.

Claim 7

A combination as defined in claim 5 in which said member edge slants from said member corner toward said member, and in which said tab edge slants from said tab corner towards said tab, whereby said tab is enabled to swing from a position in a plane parallel to said member into angular positions on either side of said plane.

Claim 8

A fastening device for releasably connecting two members together, the combination including: a. a member having a first and second surface terminating in an edge providing a member corner, b. at least one non-overlapping tab extending outwardly from the edge of said member, said tab having first and second surfaces terminating in a tab edge which provides a tab corner, said member and said tab being positioned adjacent to each other with said corners being positioned adjacent to each other, and with said tab and said member being offset from each other, c. integral hinge means positioned at said corners for connecting said member and said tab and permitting said tab to swing into different angular positions, d. at least one pin extending and supported from said first surface of said member, said pin being adjacent to said member edge and disposed inwardly of said member edge from said tab so that said pin is offset along said member edge from which said tab extends, and e. said pin and said tab on said member being adapted to be removably connected to a respective tab and pin of another member whereby a plurality of members are connected together.

Claim 9

A fastening device for releasably connecting two members together, the combination including: a. a member having a first and second surface terminating in an edge providing a member corner, b. at least one non-overlapping tab extending outwardly from the edge of said member, said tab having first and second surfaces terminating in a tab edge which provides a tab corner, said member and said tab being positioned adjacent to each other with said corners being positioned adjacent to each other, and with said tab and said member being offset from each other, c. integral hinge means positioned at said corners for connecting said member and said tab and permitting said tab to swing into different angular positions, d. at least one pin extending and supported from said first surface of said member, said pin being adjacent to said member edge and disposed inwardly of said member edge from said tab so that said pin is offset along said member edge from which said tab extends, and e. said pin and said tab on said member being adapted to be removably connected to a respective tab and pin of another member whereby a plurality of members are connected together.

Claim 10

A fastening device for releasably connecting one member to another, the combination: a. a plurality of members, each having a first member surface and a second member surface and a member edge to which said surfaces join, said member edge slanting inwardly from said first member surface toward said second member surface, b. at least one tab extending outwardly from but not overlapping said member edge of each of said members in a plane generally parallel to the plane of the member, each tab having a first tab surface and a second tab surface and a hole in said tab extending between said tab surfaces, said first tab surface being aligned with said second member surface, and including a tab edge extending from an end of said first tab surface to an end of said second tab surface, c. hinge means joining each tab to a member, said hinge means being positioned where said second member surface and said first tab surface are substantially aligned with each other, said hinge means permitting each tab to swing from planar alignment with the member to which it is connected by said hinge means, into various angular positions, and d. a pin extending outwardly from the second surface of each member at substantially right angles and positioned inwardly from the member edge of said member, said pins extending through said holes in said members to hingedly connect said members with their slanting member edges adjacent to each other in order to hingingly connect said members together.

Claim 11

A fastening device for releasably connecting one member to another, the combination: a. a plurality of members, each having a first member surface and a second member surface and a member edge to which said surfaces join, said member edge slanting inwardly from said first member surface toward said second member surface, b. at least one tab extending outwardly from but not overlapping said member edge of each of said members in a plane generally parallel to the plane of the member, each tab having a first tab surface and a second tab surface and a hole in said tab extending between said tab surfaces, said first tab surface being aligned with said second member surface, and including a tab edge extending from an end of said first tab surface to an end of said second tab surface, c. hinge means joining each tab to a member, said hinge means being positioned where said second member surface and said first tab surface are substantially aligned with each other, said hinge means permitting each tab to swing from planar alignment with the member to which it is connected by said hinge means, into various angular positions, and d. a pin extending outwardly from the second surface of each member at substantially right angles and positioned inwardly from the member edge of said member, said pins extending through said holes in said members to hingedly connect said members with their slanting member edges adjacent to each other in order to hingingly connect said members together.

Claim 12

A connector for use in a construction embodying a plurality of such connectors, said connectors comprising: a substantially planar base plate having a peripheral polygonal edge defining a plurality of adjoining sides; a single attachment member hingedly mounted to and extending laterally outwardly of certain of said sides, adjacent the corresponding end of each of said certain sides, said attachment member comprising a substantially planar tab having an aperture therein; connecting means formed on said base plate adjacent the opposite ends of said certain sides, for releasably engaging corresponding attachment members on adjacent ones of said connectors, said connecting means comprising upstanding pins formed on at least one face of said plate in registry with the apertures in said corresponding tabs on adjacent connectors, for insertion into said apertures in releasable frictional engagement therewith.

Claim 13
