First Claim
Patent Images
1. A non-pneumatic tire for a wheelchair or other wheeled apparatus, comprising:
- an integrally molded endless non-jointed elastomeric solid core element; and
at least one turn of a strain-resisting tensile member embedded in the interior of the solid core element and spaced substantially from both the radial innermost extent of and sidewalls of the tire, and extending continuously throughout such interior, and the tensile member being sufficiently extensible to permit snap-on mounting of the tire onto a channel-shaped rim.

Abstract
A non-pneumatic tire for a wheelchair or other wheeled apparatus includes an endless integrally molded solid core rubber tire with a tensile member embedded in the tire to minimize chance of roll-off of the tire from an associated rim. A method for producing the tire is disclosed.

9. A one-piece wheelchair tire comprising:
- a generally circular cross-sectioned integrally molded non-jointed endless elastomeric solid core element;
a slot formed at the radial inward surface of the core element; and
a continuous strain-resisting tensile member embedded in the core element intermediate the slot and approximate center of the core element, whereby the tire may be slightly stretched for installation onto a rim, while in use resisting roll-off encountered under side loading of the rim mounted tire. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-pneumatic tire assembly for a wheelchair or other wheeled apparatus, comprising:
-
a channel-shaped rim having a radial innermost portion and lateral upstanding sidewall surfaces terminating in outer edges; and a tire mounted on the rim comprising; an integrally molded endless non-jointed elastomeric solid core element seated between the sidewall surfaces; and at least one turn of a strain-resisting tensile member embedded in the interior of the solid core element and spaced substantially from both the radial innermost portion of the rim and said sidewall surfaces, and extending continuously throughout such interior; said tensile member being sufficiently extensible to permit snap-on mounting, and demounting of the tire from the rim while resisting roll-off while in assembled use on the wheelchair or other wheeled apparatus. - View Dependent Claims (16, 17, 18)

19. A one-piece solid core tire adapted to be snapped on to a channel-shaped rim member, for use in wheeled apparatus comprising:
-
an integrally molded endless and non-jointed elastomeric solid core element of toroidal shape; and a reinforcement integrally embedded interiorly within the solid core element and located near the center of the element cross section, extending throughout the interior of the element and spaced substantially from the lateral sides of the tire by intervening elastomeric material. - View Dependent Claims (20, 21, 22, 23)
