Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
A one-piece wheel of reinforced resin comprising a wheel disc having an outer face and an inner face, the latter being intended to rest against a hub, the disc being formed with a plurality of fastening holes extending from the outer face to the inner face and facilitating attachment of the wheel to the hub, further comprising a corresponding plurality of plate means of a material more rigid than said reinforced resin embedded in the disc, each of said plate means being formed with a bore, said bores being respectively aligned with the fastening holes, and the plate means having an outer face that extends out at least as far adjacent to the holes as the immediately surrounding portions of the outer face of the disc.
Claim 2
Dependent Claim
126 words
A one-piece wheel of reinforced resin comprising a wheel disc having an outer face and an inner face, the latter being intended to rest against a hub, the disc being formed with a plurality of fastening holes extending from the outer face to the inner face and facilitating attachment of the wheel to the hub, further comprising a corresponding plurality of plate means of a material more rigid than said reinforced resin embedded in the disc, each of said plate means being formed with a bore, said bores being respectively aligned with the fastening holes, and the plate means having an outer face that extends out at least as far adjacent to the holes as the immediately surrounding portions of the outer face of the disc.
Claim 3
Dependent Claim
20 words
A wheel according to claim 1 wherein the thickness of each plate means is less than that of the disc.
Claim 4
Dependent Claim
27 words
A wheel according to claim 1 wherein the area of each plate means in plan view is a multiple of the cross-sectional area of the correspOnding hole.
Claim 5
Dependent Claim

A wheel according to claim 4 wherein each plate means is trapezoidal.
Claim 7
Dependent Claim
32 words
A wheel according to claim 3 wherein each plate means is curved in cross section to permit a partial covering of it on its outer face by the material of the disc.
Claim 8
Dependent Claim
34 words
A wheel according to claim 1 wherein each plate means is formed adjacent to the bore therein with a beveled portion to facilitate centering of the wheel as it is tightened on the hub.
Claim 9
Dependent Claim
