Abstract
Abstract In this assembly the lockring is made from a flat metal strip crimped at regular intervals to curve the strip into a band. The ends of the band are riveted together to form a circular lockring. This lockring has spring fingers which alternate at different angles from one side of the lockring to grip a flange of a wheel tire rim. The lockring is fixed to a metal trim ring which underlies the outer flange of the wheel tire rim. The attached together lockring and trim ring are assembled with a molded plastic wheel cover by pins on the wheel cover passing through spaced openings in the attached together lockring and trim ring, said pins being either headed over or receiving push clips applied thereto.

Claim 1
Independent Claim
201 words
A lockring made from a flat straight strip of metal, and comprising a band of metal formed with transverse notches opening to one edge of the band and providing spring fingers between the notches, and also provided with transverse equiangularly spaced crimps increasing in depth toward the opposite edge of the band to cause said straight strip to curve into a circular band shape, the portions of the band between the crimps being in a common flat plane of said flat strip, the ends of said strip being overlapped and attached together to hold said crimped strip in circular band shape, a trim ring having a flange in a flat plane contacting said flat portions of said lockring, a plastic wheel cover having a flange in a flat plane contacting the flange of said trim ring, and means to attach said flanges of said trim ring and wheel cover to said flat portions of said lockring, said spring fingers being bent to one side of the plane of said flat portions, and said crimps extending to an opposite side of said plane of said flat portions, alternates of said spring fingers being bent to different angles relative to said flat portions.
