Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
140 words
A furniture connector assembly including a plug, a fastener, and a grommet wherein said plug has a substantially cylindrical shape and has at least one flat side face, said plug being further formed with a spigot extending radially and obliquely from said flat side face with respect to the axis of said plug, said spigot including a bore extending the entire length of said spigot, and said grommet including a substantially cylindrical shank and having a locating surface at one of its ends to abut the free end of said spigot on said plug, said grommet also having a bore passing through said shank, said bore being inclined to the axis of said shank of said grommet, said fastener passing, in use, through said bore in said spigot of said plug and into said inclined bore in said grommet shank.
Claim 2
Dependent Claim
140 words
A furniture connector assembly including a plug, a fastener, and a grommet wherein said plug has a substantially cylindrical shape and has at least one flat side face, said plug being further formed with a spigot extending radially and obliquely from said flat side face with respect to the axis of said plug, said spigot including a bore extending the entire length of said spigot, and said grommet including a substantially cylindrical shank and having a locating surface at one of its ends to abut the free end of said spigot on said plug, said grommet also having a bore passing through said shank, said bore being inclined to the axis of said shank of said grommet, said fastener passing, in use, through said bore in said spigot of said plug and into said inclined bore in said grommet shank.
Claim 3
Dependent Claim
48 words
A furniture connector assembly according to claim 1, wherein the sum of the acute angles between said axis of said plug and the direction of said bore in said plug, and said axis of said grommet and the direction of said inclined bore in said grommet, is 90°.
Claim 4
Dependent Claim
30 words
A furniture connector according to claim 1, wherein said plug includes a floor extending across said plug in a plane parallel to said direction of said bore in said spigot.
Claim 5
Dependent Claim
17 words
