Abstract
Abstract A tire rim and a pair of spider members circumferentially attached at the outer peripheries thereof at least in part to the tire rim for providing virtually uniform force distribution over the tire rim during rotational action of the vehicle wheel. The spider members are paraboloidal in shape, the inner portions of these members being adjacent to each other. The wheel is reversible offering a choice of design patterns in the spider configurations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
A reversible vehicle wheel, comprising: a tire rim forming a drop center portion with two substantially radially extending wall portions; a first disc member of a generally smooth flaring shape; and a second disc member generally of the same smooth and substantially identical shape as said first disc member, each of said first and second disc members being attached at the outer periphery thereof in surface to surface engagement respectively with each of said two wall portions, the convex surface portions of said disc members being substantially in surface-to-surface engagement at an imaginary plane radially extending and substantially bisecting the center of the drop center portion of the rim and the interface of the convex surface portions of the discs.
Claim 2
Dependent Claim
120 words
A reversible vehicle wheel, comprising: a tire rim forming a drop center portion with two substantially radially extending wall portions; a first disc member of a generally smooth flaring shape; and a second disc member generally of the same smooth and substantially identical shape as said first disc member, each of said first and second disc members being attached at the outer periphery thereof in surface to surface engagement respectively with each of said two wall portions, the convex surface portions of said disc members being substantially in surface-to-surface engagement at an imaginary plane radially extending and substantially bisecting the center of the drop center portion of the rim and the interface of the convex surface portions of the discs.
Claim 3
Dependent Claim
45 words
The reversible vehicle wheel as stated in claim 1, including: a tire mounted on said tire rim; and valve means provided on the rim and oppositely displaced from each other for inflating the tire from either side of the wheel and for providing wheel balance.
Claim 4
Dependent Claim
29 words
The reversible vehicle wheel as stated in claim 1, wherein said disc members are of steel for providing greater elastic limits to the vehicle wheel during rotational action thereof.
Claim 5
Dependent Claim
76 words
The reversible vehicle wheel as stated in claim 1, wherein each of said disc members has an axle mounting aperture at its center and a plurality of a stud-admitting apertures for mounting said wheel, the axle mounting apertures being aligned with each other and each stud mounting aperture of the first disc member being aligned with a corresponding stud mounting aperture of the second disc member for optionally mounting said vehicle wheel on either side thereof.
Claim 6
Dependent Claim
17 words
The reversible vehicle wheel as stated in claim 1, wherein said disc members have design patterns therein.
Claim 7
Dependent Claim
18 words
The reversible vehicle wheel as stated in claim 1, wherein said disc members have different design patterns therein.
Claim 8
Dependent Claim
30 words
The reversible vehicle wheel as stated in claim 1 said disc members being attached at their outer peripheries to the extending wall portions of the rim by means of welds.
Claim 9
Dependent Claim
37 words
The reversible vehicle wheel as stated in claim 7, wherein said welds are at the interface between the outer peripheries of the disc members and the radially extending wall portions of the drop center of the rim.
