Abstract
A vehicle wheel assembly for a toy vehicle including a substantially hollow tire portion including two structurally identical mating shells made of a relatively rigid plastic material, such as, polypropylene, polyethylene, or polystyrene, wherein the shells are mated along the centerline of the tire portion, a wheel portion for receiving the tire portion, and a retainer lip extending radially inwardly from each of the mating shells to frictionally engage the wheel portion and retain the shells in mating engagement on the wheel portion.
Claims6
A vehicle wheel assembly for a toy vehicle comprising:
- a substantially hollow tire portion including two structurally identical mating shells made of a relatively rigid plastic material, each of said shells including an outer annular wall, an inner annular wall generally concentric with said outer annular wall, and a side wall joining said outer and inner annular walls along their exterior edges, said shells including means for facilitating mutual alignment and support thereof and being in mating engagement along the outer peripheral center line of said tire portion;
- a wheel portion for receiving said tire portion;
- and retaining means for retaining said shell members in mating engagement on said wheel portion, said retaining means including a retainer lip extending generally radially inwardly from said inner annular walls of said mating shells for frictionally engaging said wheel portion;
- said wheel portion including a substantially cylindrical portion for receiving said shells and a flange extending radially from one end of said cylindrical portion for engaging one of said shells;
- the outer diameter of said cylindrical portion being slightly greater than the inner diameter of said retainer lip.
