Abstract
Abstract A universal joint is composed of first and second yokes each having two through holes, a hollow rectangular parallelepiped support member positioned to cooperate with the first and second yokes, the support member having five rectangular plate sections leaving a rectangular opening, and formed with four through holes, the adjacent rectangular plate sections being completely integral with each other at connecting edges thereof, and pins insertable into the through holes of the yokes and of the support member so as to connect the yokes with the support member, thereby producing a universal joint light in weight and high in torsional strength.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A universal joint, comprising: first and second yokes, each having two side sections, each of said side sections having a hole therein; a hollow rectangular parallelepiped support member positioned between the side sections of said first and second yokes, said support member having five rectangular plate sections, four of said rectangular plate sections including respective holes, each of said four rectangular plate sections being integrally connected to adjacent plate sections at adjoining edges thereof; four bushings, one each being disposed in a respective hole of said support member, each of said bushings being formed with a cylindrical opening therethrough and an annular flange section at one end thereof, said flange sections being located between the rectangular plate sections of said support member and the side sections of said yokes; and pin means inserted into the respective holes of the side sections of said yokes and the bushings disposed in said support member plate sections for pivotally coupling said yokes and support member plate sections.
Claim 2
Dependent Claim
164 words
A universal joint, comprising: first and second yokes, each having two side sections, each of said side sections having a hole therein; a hollow rectangular parallelepiped support member positioned between the side sections of said first and second yokes, said support member having five rectangular plate sections, four of said rectangular plate sections including respective holes, each of said four rectangular plate sections being integrally connected to adjacent plate sections at adjoining edges thereof; four bushings, one each being disposed in a respective hole of said support member, each of said bushings being formed with a cylindrical opening therethrough and an annular flange section at one end thereof, said flange sections being located between the rectangular plate sections of said support member and the side sections of said yokes; and pin means inserted into the respective holes of the side sections of said yokes and the bushings disposed in said support member plate sections for pivotally coupling said yokes and support member plate sections.
Claim 3
Dependent Claim
24 words
A universal joint as claimed in claim 1 wherein each of said bushings is press-fitted into one of said holes in said support member.
Claim 4
Dependent Claim
153 words
A universal joint, comprising: first and second yokes, each having two side sections, each of said side sections having a hole therein; a hollow rectangular parallelepiped support member positioned between the side sections of said first and second yokes, said support member having five rectangular plate sections, four of said rectangular plate sections including respective holes, each of said four rectangular plate sections being integrally connected to adjacent plate sections at adjoining edges thereof; four bushings, one each being disposed in a respective hole of said support member, each of said bushings being formed with a cylindrical opening therethrough; four annular resilient members, one each being disposed within a respective support member hole and about a respective bushing; and pin means inserted into the respective holes of the side sections of said yokes and the bushings disposed in said support member plate sections for pivotally coupling said yoke and support member plate sections.
Claim 5
Dependent Claim
153 words
A universal joint, comprising: first and second yokes, each having two side sections, each of said side sections having a hole therein; a hollow rectangular parallelepiped support member positioned between the side sections of said first and second yokes, said support member having five rectangular plate sections, four of said rectangular plate sections including respective holes, each of said four rectangular plate sections being integrally connected to adjacent plate sections at adjoining edges thereof; four bushings, one each being disposed in a respective hole of said support member, each of said bushings being formed with a cylindrical opening therethrough; four annular resilient members, one each being disposed within a respective support member hole and about a respective bushing; and pin means inserted into the respective holes of the side sections of said yokes and the bushings disposed in said support member plate sections for pivotally coupling said yoke and support member plate sections.
Claim 6
Dependent Claim
