Abstract
Abstract A ball joint in which a ball socket member of resilient material such as synthetic resin receives a ball stem mounted on one end of a first link. The socket member is provided with a projecting member and a receiving flange which are spaced apart so that when the socket member is inserted in an opening of a second link and is turned, the peripheral edge portion of the second link around the opening is held between the projecting member and the flange. The socket member is also provided with a projection adapted to engage in an aperture in the second link to prevent relative turning movement therebetween.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
183 words
A ball joint assembly comprising a socket member, a first link including a ball stem adapted for insertion in said socket member, said socket member including a projecting member and a receiving flange spaced from one another, and a second link having an opening through which said socket member is insertable with the ball stem engaged in said socket member, such that said second link can be brought to a position between the projecting member and receiving flange, and coupling means on said socket member and second link for holding the same together and preventing relative rotation therebetween, said coupling means being operatively engaged by turning the socket member and link relative to one another after insertion of the socket member in said opening, said coupling means including a resilient arm member extending radially from said flange and including a portion remote from said flange facing the sEcond link, and a projection extending between said second link and resilient arm member at said facing location resiliently bearing between these elements when the socket member is inserted in said opening in said second link.
Claim 2
Dependent Claim
183 words
A ball joint assembly comprising a socket member, a first link including a ball stem adapted for insertion in said socket member, said socket member including a projecting member and a receiving flange spaced from one another, and a second link having an opening through which said socket member is insertable with the ball stem engaged in said socket member, such that said second link can be brought to a position between the projecting member and receiving flange, and coupling means on said socket member and second link for holding the same together and preventing relative rotation therebetween, said coupling means being operatively engaged by turning the socket member and link relative to one another after insertion of the socket member in said opening, said coupling means including a resilient arm member extending radially from said flange and including a portion remote from said flange facing the sEcond link, and a projection extending between said second link and resilient arm member at said facing location resiliently bearing between these elements when the socket member is inserted in said opening in said second link.
Claim 3
Dependent Claim
36 words
An assembly as claimed in claim 1 wherein said second link is provided with a notch extending into said opening, said projecting member passing through said notch when the socket member is inserted in said opening.
Claim 4
Dependent Claim
19 words
An assembly as claimed in claim 1 comprising knob projections externally on said socket member to facilitate turning thereof.
Claim 5
Dependent Claim
31 words
An assembly as claimed in claim 1 wherein said socket member is provided with longitudinal slots spaced around its periphery to facilitate engagement of the ball stem in said socket member.
Claim 6
Dependent Claim
16 words
An assembly as claimed in claim 1 wherein said projection is mounted on said arm member.
Claim 7
Dependent Claim
25 words
An assembly as claimed in claim 5 wherein said coupling means comprises means on said second link for receiving said projection and holding the same.
Claim 8
Dependent Claim
27 words
An assembly as claimed in claim 6 wherein said means on the second link for receiving said projection is constituted by a hole in said second link.
Claim 9
Dependent Claim
27 words
An assembly as claimed in claim 6 wherein said means on the second link for receiving said projection is constituted by a concavity in said second link.
