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.
