Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
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 annular outer wall, an inner annular wall generally concentric with said outer wall, and a side wall joining said outer and inner 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 centerline of said tire portion; a wheel portion for receiving said tire portion; and retaining means for retaining said shell members in mating engagement with said wheel portion; said wheel portion including a first and a second member and said retaining means comprising means at respective exterior ends of said first and second members for engaging said shells and inwardly facing bonding surfaces at respective interior ends of said wheel members whereby said bonding surfaces are adapted to be bonded together to retain said shell members in mating relationship.
Claim 2
Dependent Claim
