Abstract
Abstract A ball joint consisting of a plastic one-piece molding comprises two halves having substantially the same shape and each consisting of a shell having a semi-spherical recess and a mounting portion provided on the shell for mounting the ball joint on a work. The two halves are coupled together by a hinge and are capable of being joined together face to face by bending the hinge such that one half of a ball portion of a ball stud is received in the recess of each shell. The two halves can be mounted in a face-to-face joined state in a mounting hole of a panel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
In a ball joint comprising a plastic one-piece molding for assembly with a ball stud, said molding comprising two halves having substantially the same shape and each comprising a shell having a semi-spherical recess, a mounting portion provided on said shell for mounting said ball molding on a support member, said two halves being coupled together by hinge means for relative movement between an open apart position in which said halves are attached only by said hinge means and a closed position during assembly with a ball stud such that one half of a ball portion of a ball stud is received in said recess of each shell, said two halves being inseparable when in said closed position, each of said halves being coupled by a respective hinge member to a connecting member which bridges said halves in said closed position, and wherein said mounting portions project from respective side surfaces of said shells.
Claim 2
Dependent Claim
154 words
In a ball joint comprising a plastic one-piece molding for assembly with a ball stud, said molding comprising two halves having substantially the same shape and each comprising a shell having a semi-spherical recess, a mounting portion provided on said shell for mounting said ball molding on a support member, said two halves being coupled together by hinge means for relative movement between an open apart position in which said halves are attached only by said hinge means and a closed position during assembly with a ball stud such that one half of a ball portion of a ball stud is received in said recess of each shell, said two halves being inseparable when in said closed position, each of said halves being coupled by a respective hinge member to a connecting member which bridges said halves in said closed position, and wherein said mounting portions project from respective side surfaces of said shells.
Claim 3
Dependent Claim
54 words
The ball joint according to claim 1 wherein each of said shells comprises an exterior, bottom surface oppositely located with respect to an opening of said recess through which said ball stud projects from said recess, and wherein said connecting member engages each of said bottom surfaces, in said closed position of said halves.
Claim 4
Dependent Claim
20 words
The ball joint according to claim 1 wherein said hinges are provided on opposing ends formed on said connecting member.
Claim 5
Dependent Claim
41 words
The ball joint according to claim 1 wherein each of said halves further comprises a projection removably extending into an aperture formed in said connecting member, in order to promote alignment of said recesses in the closed position of said halves.
Claim 6
Dependent Claim
41 words
The ball joint according to claim 3 wherein each of said halves comprises a semi-annular, radially outwardly projecting flange formed adjacent said opening and spaced from said mounting portion for cooperation therewith to retain said ball joint upon said support member.
Claim 7
Dependent Claim
197 words
A ball joint linkage comprising a plastic one-piece molding for assembly with a ball stud, said molding comprising two halves having substantially the same shape and each comprising a shell having a semi-spherical recess, a mounting portion provided on said shell for mounting said ball molding on a support member, said two halves being coupled together by hinge means for relative movement between an open apart position and a closed position during assembly with a ball stud such that one half of a ball portion of a ball stud is received in said recess of each shell, said two halves being inseparable when in said closed position to form a ball joint, each of said halves being coupled by a respective hinge member to a connecting member which bridges said halves in said closed position, each of said halves further comprising a semi-annular, radially outwardly projecting flange, said support member having an aperture through which said ball stud projects in said assembly and closed position of said halves, wherein the periphery of said support member aperture is clamped between said mounting portions and said respective flanges to secure mounting of said ball joint on said support member.
Claim 8
Dependent Claim
197 words
A ball joint linkage comprising a plastic one-piece molding for assembly with a ball stud, said molding comprising two halves having substantially the same shape and each comprising a shell having a semi-spherical recess, a mounting portion provided on said shell for mounting said ball molding on a support member, said two halves being coupled together by hinge means for relative movement between an open apart position and a closed position during assembly with a ball stud such that one half of a ball portion of a ball stud is received in said recess of each shell, said two halves being inseparable when in said closed position to form a ball joint, each of said halves being coupled by a respective hinge member to a connecting member which bridges said halves in said closed position, each of said halves further comprising a semi-annular, radially outwardly projecting flange, said support member having an aperture through which said ball stud projects in said assembly and closed position of said halves, wherein the periphery of said support member aperture is clamped between said mounting portions and said respective flanges to secure mounting of said ball joint on said support member.
