Abstract: A non-pneumatic tire for a vehicle is provided that has a body of elastic material and a circumferentially-extending crown portion that has a running surface and circumferentially-extending sidewalls joined to the crown portion. A number of radially-extending springs are at least partially embedded within the tire body. An internal support structure includes a circumferentially extending backbone and at least one connector component that connects the backbone to each of the springs.

Abstract: A non-pneumatic tire for a vehicle featuring a body of elastic material and having a circumferentially-extending crown portion featuring a running surface and circumferentially-extending sidewalls joined to the crown portion. The side walls terminate in circumferentially-extending beads which are adapted to engage the rim of a vehicle wheel. A number of radially-extending and circumferentially-spaced compound-curve springs made of a composite material are at least partially embedded within the crown portion and the sidewalls. The curved springs have ends terminating within the beads of the tire body. A circumferentially-extending belt constructed of a high-strength and low stretch material is positioned radially outside of the compound-curve springs.

Abstract: A non-pneumatic bicycle tire has a main tire body and at least one rim retaining member. The main tire body includes a rim engagement portion and a ground contact portion with a ground contact surface. The at least one rim retaining member is fixedly attached to the rim engagement portion. The at least one rim retaining member includes a pair of elastically deformable rim retaining portions extending laterally in opposite axial directions. Preferably, the main tire body has a plurality of the rim retaining members coupled thereto. In one embodiment, the rim retaining members are attached to the inner surface of the main tire body, while in another embodiment, the rim retaining members are embedded into the rim engagement portion of the main tire body.

Abstract: A non-pneumatic resilient tire which derives its capacity to bear a load from laminated elements capable of supporting bending moments. The laminated elements include a stack of resilient sheets superposed and separated by a layer of rubber adhering to the latter, forming a beam capable of undergoing bending stress.

Abstract: A non-pneumatic tire comprises circumferentially-spaced support elements joined together by an interconnection structure with the interposition of flexible joints, so as to ensure good overall operation.

Abstract: A vehicle tire includes a rubber or elastomer tire body which has a circumferentially extending crown portion and opposite sidewalls joining the crown portion. The sidewalls terminate in circumferentially extending beads adapted to be received in a vehicle wheel rim. A plurality of circumferentially spaced arcuate leaf springs are, at their ends, resiliently embedded into the respective beads. The leaf springs support parts of the internal face of the crown portion.

Abstract: A pair of roller skis 300 each constituted by attaching elastic wheels 302 to a boot-placing plate 301 in the front thereof and at the back thereof. The elastic wheels 302 each comprises a wheel supporting means having a circular rim part on the outer periphery and a tire part mounted on the circular rim part of the wheel supporting means and being elastically deformable in the direction perpendicular to the running direction of the wheel. Each elastic wheel 302 enables the running direction thereof to be simply changed with the wheel shaft kept in the same direction, and utilization of the features permits a skier to operate the roller skis with a feeling similar to that afforded by conventional snow skis.

Abstract: The improved wheel assembly includes a hub member having a cylindrical casing with an axial bore adapted to receive the end of a wheel axle, and a plurality of threaded bolts which threadably engage conventional lug nuts; a tubeless, airless tire member having three continuous supporting belts, a plurality of reverse inclined Z-shaped supporting rods connected to each other and to each supporting belt, and a transverse central opening adapted to receive the hub; and an annular cap member adapted to engage the outer periphery of the central opening of the tire member and to receive the bolts of the hub member.
