Dual rim spacer

Abstract

A non-compressible spacer for use in mounting dual rims on a wheel. Spacer has an annular medial portion with radially outwardly directed uniformly spaced undulations. The undulations are marquise-shaped areas alternating with .[.apexly opposed cone-shaped.]. .Iadd.opposed colinearly aligned radially outwardly concave .Iaddend.areas. The ends of the marquise-shaped areas and the space between the .[.cone-shaped.]. .Iadd.opposed colinearly aligned radially outwardly concave .Iaddend.areas seat on the wheel felloe.

What is claimed is: 
     
       1. A non-compressible spacer for use in mounting dual rims on a vehicle wheel, characterized in that, said spacer has an annular medial portion having a plurality of radially outwardly directed substantially uniformly spaced undulations comprising marquise-shaped areas alternating with apexly opposed cone-shaped areas, the radially inner dimensions of said spacer being such that the space between said marquise-shaped areas and said cone-shaped areas will slidingly engage and seat on the load-bearing surface of a wheel for dual rims.   
     
     
       2. A non-compressible spacer according to claim 1, further characterized in that, lateral flanges formed integrally with said annular medial portion comprise circumferentially undulating flanges directed radially outwardly with axially outer surfaces for seating against opposed flanges of said dual rims, said circumferential undulations being directed radially inwardly laterally of a marquise-shaped area and directed radially outwardly laterally of a cone-shaped area. .Iadd. 3. A non-compressible spacer for use in mounting dual rims on a vehicle wheel, characterized in that,   said spacer has an annular medial portion having a plurality of radially outwardly directed substantially uniformly spaced undulations comprising marquise-shaped areas alternating with pairs of opposed colinearly aligned radially outwardly concave areas, the radially inner dimensions of said spacer being such that the space between said marquise-shaped areas and said opposed colinearly aligned radially outwardly concave areas will slidingly engage and seat on the load-bearing surface of a wheel for dual rims. .Iaddend..Iadd.4. A non-compressible spacer according to claim 3, further characterized in that,   lateral flanges formed integrally with said annular medial portion comprise circumferentially undulating flanges directed radially outwardly with axially outer surfaces for seating against opposed flanges of said dual rims, said circumferential undulations being directed radially inwardly laterally of a marquise-shaped area and directed radially outwardly laterally of an opposed colinearly aligned radially outwardly concave area..Iaddend.
