Abstract
Abstract A universal joint assembly for tubular members for use as structural elements for furniture or the like characterized in that the jointing assembly comprises a central module body shaped as a cube, each face of the cube having a circular cavity or recess and at least one connector piece. The connector piece is provided with a circular projection fitting into any one of the circular recesses of the module body. A jointing screw engages through a hole in the connector and is received in a threaded bore in the module body to securely fasten the connector piece to the module body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
Universal jointing assembly comprising a module body having a plurality of faces, means defining a recess in each of the faces of said module body, at least one connector piece having a projection engaged in one of said recesses and at least one pair of leg members, a jointing screw member securing said connector piece to said module body, at least one tubular member telescopically engaged over said connector piece and means for expanding said legs members to engage the interior walls of said tubular member.
Claim 2
Dependent Claim
86 words
Universal jointing assembly comprising a module body having a plurality of faces, means defining a recess in each of the faces of said module body, at least one connector piece having a projection engaged in one of said recesses and at least one pair of leg members, a jointing screw member securing said connector piece to said module body, at least one tubular member telescopically engaged over said connector piece and means for expanding said legs members to engage the interior walls of said tubular member.
Claim 3
Dependent Claim
24 words
Universal jointing assembly as claimed in claim 1 wherein said module body member is shaped as a cube having six substantially square shaped faces.
Claim 4
Dependent Claim
57 words
Universal jointing assembly as claimed in claim 2 wherein said adaptor includes four post members having an inner surface conforming to said connector piece and right angled outer face portions conforming to the corners of a tubular member of square cross section, said post members connected to a web overlying the axial end of said connector piece.
Claim 5
Dependent Claim
