Abstract
Abstract A bearing fastener having an annular bearing portion including an annular cylindrical bearing sleeve portion and an integral radially outwardly extending annular head portion, an annular locking ring portion, and a resilient connecting portion integral with the head portion and the locking ring portion. In the bearing assembly, the bearing sleeve portion is received over a cylindrical bearing portion of a stud connecting two relatively movable members. The annular locking ring portion is received in an annular groove or notch in the stud to secure the bearing portion on the stud.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
A bearing fastener assembly for attaching two platelike members for relative movement, comprising: a stud adapted to be secured at one end to one of the members and having at the opposite end an annular groove and intermediate the groove and said one end exhibiting a generally cylindrical bearing portion, and an integral bearing fastener comprising a bearing grommet portion including a central annular bearing portion encircling the bearing portion of said stud and a pair of opposed radially outwardly extending integral head portions adapted to overlie and retain the second member, an annular locking ring portion disposed within the annular groove and encircling said stud retaining said bearing grommet portion and the second member on said stud, and a resilient connecting portion integral with said bearing grommet portion and said locking ring portion interconnecting said locking ring and the adjacent head portion of said bearing grommet portion.
Claim 2
Dependent Claim
148 words
A bearing fastener assembly for attaching two platelike members for relative movement, comprising: a stud adapted to be secured at one end to one of the members and having at the opposite end an annular groove and intermediate the groove and said one end exhibiting a generally cylindrical bearing portion, and an integral bearing fastener comprising a bearing grommet portion including a central annular bearing portion encircling the bearing portion of said stud and a pair of opposed radially outwardly extending integral head portions adapted to overlie and retain the second member, an annular locking ring portion disposed within the annular groove and encircling said stud retaining said bearing grommet portion and the second member on said stud, and a resilient connecting portion integral with said bearing grommet portion and said locking ring portion interconnecting said locking ring and the adjacent head portion of said bearing grommet portion.
Claim 3
Dependent Claim
36 words
The bearing fastener assembly defined in claim 1, characterized in that said locking ring portion includes a plurality of resilient locking fingers biased against said stud within the annular groove preventing inadvertent removal of the ring.
Claim 4
Dependent Claim
42 words
The bearing fastener assembly defined in claim 2, characterized in that said resilient connecting portion tensions the integral edge of said locking ring portion, biasing the opposed edge of said ring portion against the adjacent head portion of said bearing grommet portion.
Claim 5
Dependent Claim
50 words
The bearing fastener assembly defined in claim 1, characterized in that the axial length of said bearing grommet portion is approximately equal to the axial length of the bearing portion of the stud, and said locking ring portion is received against the adjacent head portion of said bearing grommet portion.
Claim 6
Dependent Claim
58 words
The bearing fastener assembly defined in claim 4, characterized in that the length of said resilient interconnecting portion is approximately equal to the radial width of said adjacent head portion, and said connecting portion tensions the integral edge of said locking ring portion away from said adjacent head portion, biasing the opposed edge against the adjacent head portion.
Claim 7
Dependent Claim
28 words
The bearing fastener assembly defined in claim 1, characterized in that said integral bearing fastener is formed of a resilient plastic material having a low coefficient of friction.
Claim 8
Dependent Claim
28 words
A bearing fastener assembly defined in claim 1, characterized in that the opposed outer surfaces of said head portions are generally planer to provide a smooth bearing surface.
Claim 9
Dependent Claim
22 words
The bearing fastener assembly defined in claim 7, characterized in that the opposed head portions have an arcuate radially outer exterior surface.
