Abstract
Abstract Several rattan furniture joints are disclosed, one comprising a T-shaped connection for two rattan poles, a second joint having the poles parallel and alongside one another, and the third joint having the poles connected end-to-end. In each of these three types of joint two internally threaded plastic inserts are pinned in aligned openings in the poles, and a threaded male stud or shank member is provided to connect the two poles. The method provides for rotating one plastic insert with respect to the other to facilitate the assembly of the parts, and this assembly step can be achieved by providing a slotted head on at least the rotatable insert, or merely by virtue of the fact that one pole can be rotated with respect to the other during assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A mechanical joint for rattan furniture comprising: (a) a first cylindrical member having an opening, (b) a second cylindrical member having an opening aligned with said first member opening, (c) an internally threaded plastic sleeve in each of said openings, said sleeves extending substantially the full length of said openings, (d) means for anchoring at least one of said sleeves in its associated opening and with the other sleeve being slidably seated in its opening for retention therein, (e) a screw threaded steel shank threadably received in both sleeves, said shank having a length significanly less than the combined axial length of said sleeves, said shank having no head thereon to provide both ends of said steel shank spaced axially inwardly of and within the plastic sleeves, and said shank being threaded in the same direction throughout its length, and (f) means for rotating the other sleeve to assemble said members tightly together.
Claim 2
Dependent Claim
153 words
A mechanical joint for rattan furniture comprising: (a) a first cylindrical member having an opening, (b) a second cylindrical member having an opening aligned with said first member opening, (c) an internally threaded plastic sleeve in each of said openings, said sleeves extending substantially the full length of said openings, (d) means for anchoring at least one of said sleeves in its associated opening and with the other sleeve being slidably seated in its opening for retention therein, (e) a screw threaded steel shank threadably received in both sleeves, said shank having a length significanly less than the combined axial length of said sleeves, said shank having no head thereon to provide both ends of said steel shank spaced axially inwardly of and within the plastic sleeves, and said shank being threaded in the same direction throughout its length, and (f) means for rotating the other sleeve to assemble said members tightly together.
Claim 3
Dependent Claim
37 words
The joint defined by claim 1 wherein said one sleeve anchoring means comprises at least one pin oriented normal to the axis of said threaded sleeve, said one pin located adjacent an inner end of said sleeve.
Claim 4
Dependent Claim
50 words
The joint defined by claim 1 wherein means is provided for anchoring said other sleeve in its associated opening, said anchoring means for each sleeve comprising at least one pin oriented normal to the axis of said threaded sleeve, said one pin located adjacent a inner end of said sleeve.
Claim 5
Dependent Claim
38 words
The joint defined by claim 1 wherein said one sleeve anchoring means comprises ribs defined on the outside surface thereof, said sleeve formed from a plastic material somewhat harder than said material from which said members are fabricated.
Claim 6
Dependent Claim
54 words
The joint defined by claim 1 wherein said means for rotating said other sleeve comprises a headed annular portion thereof, said headed portion defining a flange adapted to abut the associated member, and said headed portion defining a tool receiving socket to facilitate rotation of said other sleeve with respect to said one sleeve.
Claim 7
Dependent Claim
58 words
The joint defined by claim 5 wherein said joint is T-shaped with said cylindrical members oriented perpendicular to one another, said first cylindrical member having said one sleeve anchored in an axial end opening at one end thereof, and said first cylindrical member having said one end formed to fit the cylindrical contour of said second cylindrical member.
Claim 8
Dependent Claim
24 words
The joint defined by claim 5 wherein said cylindrical members have their respective openings oriented diametrically and said aligned openings extending through said members.
