Abstract
Abstract A wheel adapted to be rotated about a normally horizontal axis perpendicular to a normal direction of travel has a hub centered on the axis and a central core body made of a hard material and coaxially surrounding the hub. This core body has an annular outer surface centered on and turned radially away from the axis and having a pair of axially opposite edges. A pair of similar side-wall bodies of a soft material symmetrically flank and are joined to the core body and each have an annular surface having a radial outer edge joining the core body at a respective one of the edges thereof and a radial inner edge at the hub. The surfaces of the side-wall bodies curve continuously from their outer edges to their inner edges.

Total Claims: 8
Claim 1
Independent Claim
148 words
A wheel adapted to be rotated about a normally horizontal axis perpendicular to a normal direction of travel, the wheel comprising: a hub centered on the axis; a central core body made of a hard material and coaxially surrounding the hub, the core body having an annular outer surface centered on and turned radially away from the axis and having a pair of axially opposite edges; and a pair of similar side-wall bodies of a soft material symmetrically flanking and joined to the core body and each having an annular surface having a radial outer edge joining the core body at a respective one of the edges thereof and a radial inner edge at the hub, the outer surfaces of the side-wall bodies meeting the outer surface of the core body at the edges thereof and forming a smooth continuation of the outer surface of the core body.
Claim 2
Dependent Claim
