Abstract

A wheel is composed of a rigid plastic inner section forming the wheel hub and rim and a resilient plastic tire section encircling the rim. A key formed integrally with the rim extends radially outward therefrom and interlockingly projects into the tire so as to mechanically connect the tire to the rim all around the wheel. The key can be formed with axially extending portions spaced radially outboard of the rim and terminating flush with the outer surface of the tire section so as to provide colored side wall decorations at one or both sides of the wheel.

Claims

1. An improved wheel comprising

A. a discoid section

(1) shaped to define a wheel rim, a wheel hub and connections between the rim and hub, and

(2) being composed of a first plastic material having selected physical characteristics,

B. a generally toroidal tire section

(1) encircling the discoid section rim, and

(2) being composed of a second plastic material having at least one physical characteristic different from those of the first plastic material, and

C. means mechanically connecting the tire section to the rim around the circumference of the discoid section, said connecting means including one or more portions

(1) extending appreciably radially beyond the outermost radial extent of said rim into said tire section, and

(2) extending axially to the outer surface of the tire section terminating flush therewith on at least one tire section sidewall at a location spaced radially outward from the periphery of said rim.

2. The wheel defined in claim 1 wherein the two sections differ in their elastomeric characteristic.

3. The wheel defined in claim 1 wherein the two sections differ in their color characteristic.

4. The wheel defined in claim 1 wherein said one or more portions includes a circular axially extending flange spaced radially out from the rim thereby defining a circular stripe on at least one tire section side wall.

5. The wheel defined in claim 4 wherein the plastic materials of the discoid and tire sections have different colors so that said one or more portions constitutes a tire section side wall decoration.

6. The wheel defined in claim 4 wherein said flange extends to the outer surfaces of the tire section on both sides of the wheel so as to define stripes on both the tire section side walls.

7. The wheel defined in claim 6 wherein at least one edge of the flange is formed with a circumferential array of recesses so that the stripe formed by the flange is interrupted on at least one tire section side wall.

8. An improved wheel comprising

A. a discoid section shaped to define a wheel rim, a wheel hub and connections between the rim and hub,

B. a toroidal tire section encircling the discoid section rim, and

C. plastic tire section sidewall decorating means

(1) projecting radially out from the discoid section rim appreciably beyond the outermost radial extent of said rim into the tire section,

(2) having axially extending portions spaced radially outboard of the rim periphery which terminate and define exposed surfaces at the outer surface of the tire section on at least one side of the tire section, and

(3) said decorating means and said tire section being colored differently so that said exposed surfaces of the decorating means appear as contrasting colored indicia at said surface of the tire section.

9. The wheel defined in claim 8 wherein said decorating means comprise

A. a generally flat ring spaced concentrically around said rim, and

B. means defining connections between said rim and said ring.

10. The wheel defined in claim 9 wherein said ring and connections are formed integrally with said discoid section.

11. The wheel defined in claim 10 wherein the opposite edges of said flat ring terminate at the outer surfaces of both tire section side walls so as to form circular side wall stripes at both sides of the tire section.

12. The wheel defined in claim 11 wherein at least one edge of said ring is formed with a circular array of recesses so that the circular side wall stripe formed by that edge is interrupted.

13. The wheel defined in claim 8 wherein

A. said tire section is black, and

B. said discoid section and said decorating means are colored differently from black.
