Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 246 words
A furniture connector for connecting two furniture parts aligned and abutted at a right angle to each other, said furniture connector comprising: a dowel-like housing having a central axis, said housing having axially extending therethrough an opening, said housing adapted to be fitted within a bore in a first furniture part and including a portion adapted to be positioned adjacent a second furniture part to be connected to the first furniture part, said portion of said housing being axially divided by at least one separating slot extending through said portion from said opening to the outer surface of said housing; an elongated expansion member having an axis and extending through said portion of said housing, said expansion member having head means within said opening for rotation of said expansion member and thread means adapted to be threadably anchored in the second furniture part upon rotation of said head means and for thereby moving said housing and the first furniture part axially of said expansion member toward the second furniture part; said axes of said housing and said expansion member extending at a right angle to each other; and clamping means, positioned to be urged by said head means upon rotation thereof, for causing said housing, upon movement thereof toward the second furniture part, to expand outwardly against a wall of the bore formed in the first furniture part, in separate directions extending on opposite sides of said expansion member and diverging outwardly from said axis thereof.
Claim 2
Dependent Claim 246 words
A furniture connector for connecting two furniture parts aligned and abutted at a right angle to each other, said furniture connector comprising: a dowel-like housing having a central axis, said housing having axially extending therethrough an opening, said housing adapted to be fitted within a bore in a first furniture part and including a portion adapted to be positioned adjacent a second furniture part to be connected to the first furniture part, said portion of said housing being axially divided by at least one separating slot extending through said portion from said opening to the outer surface of said housing; an elongated expansion member having an axis and extending through said portion of said housing, said expansion member having head means within said opening for rotation of said expansion member and thread means adapted to be threadably anchored in the second furniture part upon rotation of said head means and for thereby moving said housing and the first furniture part axially of said expansion member toward the second furniture part; said axes of said housing and said expansion member extending at a right angle to each other; and clamping means, positioned to be urged by said head means upon rotation thereof, for causing said housing, upon movement thereof toward the second furniture part, to expand outwardly against a wall of the bore formed in the first furniture part, in separate directions extending on opposite sides of said expansion member and diverging outwardly from said axis thereof.
Claim 3
Dependent Claim 18 words
A connector as claimed in claim 1, wherein said portion of said housing has a planar outer surface.
Claim 4
Dependent Claim 20 words
A connector as claimed in claim 2, wherein said planar outer surface is adapted to contact the second furniture part.
Claim 5
Dependent Claim 15 words
A connector as claimed in claim 1, comprising two said slots positioned in staggered positions.
Claim 6
Dependent Claim 40 words
A connector as claimed in claim 1, wherein said opening has inclined surfaces converging axially of said expansion member toward the second furniture part, and said clamping means includes inclined faces complementary to and in engagement with said inclined surfaces.
Claim 7
Dependent Claim 17 words
A connector as claimed in claim 5, wherein said inclined faces are integral with said expansion member.
Claim 8
Dependent Claim 24 words
A connector as claimed in claim 5, wherein said inclined faces are on a separate clamping member which is mounted on said expansion member.
Claim 9
Dependent Claim 24 words
A connector as claimed in claim 7, wherein said clamping member has female threads in engagement with said thread means of said expansion member.
Claim 10
Dependent Claim 261 words
A furniture connector for connecting two furniture parts aligned and abutted at a right angle to each other, said furniture connector comprising: a dowel-like housing having a central axis, said housing having axially extending therethrough an opening, said housing adapted to be fitted within a bore in a first furniture part and including a portion adapted to be positioned adjacent a second furniture part to be connected to the first furniture part, said housing comprising a cylinder of circular cross-section, the circumference of said cylinder being discontinued at said portion, said portion having the configuration of a circular segment directed toward the interior of said cylinder; an elongated expansion member having an axis and extending through said circular segment portion of said housing, said expansion member having head means within said opening for rotation of said expansion member and thread means adapted to be threadably anchored in the second furniture part upon rotation of said head means and for thereby moving said housing and the first furniture part axially of said expansion member toward the second furniture part; said axes of said housing and said expansion member extending at a right angle to each other; and said circular segment portion forming clamping means, to be urged by said head means upon rotation thereof, for causing said cylinder of said housing, upon movement thereof toward the second furniture part, to expand outwardly against a wall of the bore formed in the first furniture part, in separate directions extending on opposite sides of said expansion member and diverging outwardly from said axis thereof.
Claim 11
Dependent Claim 261 words
A furniture connector for connecting two furniture parts aligned and abutted at a right angle to each other, said furniture connector comprising: a dowel-like housing having a central axis, said housing having axially extending therethrough an opening, said housing adapted to be fitted within a bore in a first furniture part and including a portion adapted to be positioned adjacent a second furniture part to be connected to the first furniture part, said housing comprising a cylinder of circular cross-section, the circumference of said cylinder being discontinued at said portion, said portion having the configuration of a circular segment directed toward the interior of said cylinder; an elongated expansion member having an axis and extending through said circular segment portion of said housing, said expansion member having head means within said opening for rotation of said expansion member and thread means adapted to be threadably anchored in the second furniture part upon rotation of said head means and for thereby moving said housing and the first furniture part axially of said expansion member toward the second furniture part; said axes of said housing and said expansion member extending at a right angle to each other; and said circular segment portion forming clamping means, to be urged by said head means upon rotation thereof, for causing said cylinder of said housing, upon movement thereof toward the second furniture part, to expand outwardly against a wall of the bore formed in the first furniture part, in separate directions extending on opposite sides of said expansion member and diverging outwardly from said axis thereof.
