Abstract
Abstract A furniture joint for joining hollow-ended structural sections of modular furniture and especially the highly finished elements employed in the steel-and-glass-look type of furniture. This type of furniture requires a continuity of surface appearances having mirror-like attributes. The joining of the hollow-ended sections which advantageously may be cut from available lengths of mirrorized plastic tubing is accomplished by the use of a splined collar of elastomeric material and connector spuds which fit in the annular spaces between the connector arms and the tubing. The splines of the collar are adapted to be torsionally distorted ("squeegeed") during assembly. This distortion of the splines prevents the joint from inadvertently coming apart under the axial strain that the furniture joint may be expected to carry in normal use. However, the joint may be disassembled and the elements reused if rotational twisting is employed together with a pulling effort.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A furniture joint comprising a connector having at least one spud arm, a splined collar of elastomeric material adapted to fit snuggly over said spud arm, said splined collar having a flange at one end thereof partially enclosing said one end and a plurality of bumper elements extending inwardly and axially from said flange, said bumper elements being located so as to contact an end surface of said spud arm, and a hollow-ended member having an internal diameter dimensioned to fit over and helically squeegee and elongate the splines of said collar during assembly.
Claim 2
Dependent Claim
94 words
A furniture joint comprising a connector having at least one spud arm, a splined collar of elastomeric material adapted to fit snuggly over said spud arm, said splined collar having a flange at one end thereof partially enclosing said one end and a plurality of bumper elements extending inwardly and axially from said flange, said bumper elements being located so as to contact an end surface of said spud arm, and a hollow-ended member having an internal diameter dimensioned to fit over and helically squeegee and elongate the splines of said collar during assembly.
Claim 3
Dependent Claim
42 words
A furniture joint according to claim 1 wherein said collar is dimensioned so as to fit over said spud arm with sufficient snugness to prevent rotation thereon when said hollow member is twisted with respect to said spud arm during said assembly.
Claim 4
Dependent Claim
53 words
A furniture joint in accordance with claim 1 wherein said internal diameter of said hollow-ended member is so dimensioned and said elastomeric material of said splines is so selected as to cause said helical squeegee to remain set during the application of a thrust and twist opposite to that applied during said assembly.
Claim 5
Dependent Claim
26 words
A furniture joint in accordance with claim 1 wherein said connector is of mirror-finished metal and wherein said hollow-ended member is of externally-mirrorized extruded plastic tubing.
Claim 6
Dependent Claim
58 words
A furniture joint in accordance with claim 4 wherein said spud arm includes a portion having an axial length longer than the the axial length of said spline collar by an amount sufficient to compensate for the elongation of said collar during said assembly whereby said hollow-ended externally mirrorized member and said mirror-finished connector may be smoothly abutted.
Claim 7
Dependent Claim
100 words
A collar for insertion in the annular clearance between the male and female members of a furniture joint comprising a substantially cylindrical elastomeric shell having a plurality of elongate splines thereon, said shell being of a material having sufficient resiliency to undergo elongation during assembly of said members, a flange at one end of said shell partially enclosing said one end, and a plurality of bumper elements extending inwardly and axially from said flange, said bumper elements being located so as to space said flange a predetermined distance away from an end surface of one of said furniture joint members.
Claim 8
Dependent Claim
100 words
A collar for insertion in the annular clearance between the male and female members of a furniture joint comprising a substantially cylindrical elastomeric shell having a plurality of elongate splines thereon, said shell being of a material having sufficient resiliency to undergo elongation during assembly of said members, a flange at one end of said shell partially enclosing said one end, and a plurality of bumper elements extending inwardly and axially from said flange, said bumper elements being located so as to space said flange a predetermined distance away from an end surface of one of said furniture joint members.
