Abstract
Abstract A one-piece molded wheel which may be used on a wide variety of vehicles is disclosed. The wheel includes a generally annular tire portion integral with a central spoke portion and a hub portion. The generally annular tire portion has a U-shaped cross section with a pair of open edges which may receive a decorative annular band to give the tire portion the appearance of having a decorative side wall. The spoke portion comprises a plurality of spoke members which cooperate to define substantially U-shaped sections composed of planar members with each section oppositely oriented from each adjacent section. The configuration of the wheel makes it possible to manufacture it in a one-step molding operation.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
204 words
A one-piece molded wheel comprising: a generally annular tire portion, a central spoke portion, and a hub portion; said generally annular tire portion comprising a radially outer generally cylindrical peripheral portion having tread means extending outwardly thereof for engaging a surface upon which the wheel is rolled, a radially inner generally cylindrical rim portion disposed radially inwardly of the tire portion, and an intermediate annular portion disposed generally transversely of said peripheral and rim portions extending between corresponding axial edges thereof and formed integrally therewith, and a plurality of support members each having one end integral with said peripheral portion and its other end integral with said rim portion; said central spoke portion comprising a plurality of spoke members, each spoke member having one end integral with said rim portion of the annular tire portion and the other end integral with said hub portion to provide support therefor; said hub portion being substantially cylindrically shaped and defining an opening for receiving an axle of a vehicle in rotatable relationship therewith; an annular band disposed between corresponding axial edges of said rim and said peripheral portions opposite from said annular portion; and means forming part of said annular portion for securing said annular band thereto.
Claim 2
Dependent Claim
204 words
A one-piece molded wheel comprising: a generally annular tire portion, a central spoke portion, and a hub portion; said generally annular tire portion comprising a radially outer generally cylindrical peripheral portion having tread means extending outwardly thereof for engaging a surface upon which the wheel is rolled, a radially inner generally cylindrical rim portion disposed radially inwardly of the tire portion, and an intermediate annular portion disposed generally transversely of said peripheral and rim portions extending between corresponding axial edges thereof and formed integrally therewith, and a plurality of support members each having one end integral with said peripheral portion and its other end integral with said rim portion; said central spoke portion comprising a plurality of spoke members, each spoke member having one end integral with said rim portion of the annular tire portion and the other end integral with said hub portion to provide support therefor; said hub portion being substantially cylindrically shaped and defining an opening for receiving an axle of a vehicle in rotatable relationship therewith; an annular band disposed between corresponding axial edges of said rim and said peripheral portions opposite from said annular portion; and means forming part of said annular portion for securing said annular band thereto.
Claim 3
Dependent Claim
19 words

Claim 8
Dependent Claim
22 words
The one-piece molded wheel of claim 4 wherein an annular band is disposed on the open edges of said substantially U-shaped section.
Claim 9
Dependent Claim
24 words
The one-piece molded wheel of claim 1 wherein said annular band has at least one visually observable characteristic which is different from said wheel.
Claim 10
Dependent Claim
17 words
