Filed:

May 8, 1979

Appl. No.:

6/037393

Inventors:

Ransome J. Wyman - Calabases CA
Richard A. Alshin - Long Beach CA
Charles H. Gilbert - Fullerton CA

Assignee:

Carefree Bicycle Tire Company - Marina Del Rey CA

International Classification:

B60C 712

US Classification:

152327

Abstract:

A solid monolithic tire for use on a wheel rim can be improved by incorporating within the tire a circumferentially extending tunnel formed on the inside of the tire body. Further, the tire body has inclined side walls that converge outwardly to form a V-shaped cross section. The apex of this V-shaped cross section forms the tread portion of the tire. Each of the side walls of the tire terminate in a thickened portion which forms a bead shoulder capable of seating on the bead flanges of the wheel rim to which the tire is mounted. Extending down through the thickened portion of either side of the tire is a bead which has a lower bead wall on the portion most distal to the thickened portion. A bead cord extends circumferentially embedded within the bead near the lower bead wall. The process by which the tire is formed allows the bead cord to be positioned in its appropriate place within the bead.

International Classification:

US Classification:

152322

Abstract:

A monolithic non-pneumatic urethane tire for use on a wheel rim of the type having a pair of laterally spaced bead flanges formed with wheel rim side walls which extend upwardly from the bottom of the wheel rim is improved by providing a tire body with certain structural features and locating a tubular insert inside the tire body. The tire body has a circumferentially extending tunnel on its inside and includes side walls which converge outwardly to a thickened portion. The thickened portion forms a bead shoulder that seats on top of the bead flanges of the wheel rim and also includes a bead which extends downwardly into the wheel rim adjacent the side walls of the wheel rim. The tubular insert is a semiresilient hollow tube mounted within the tunnel of the tire body to maintain the bead portion of the tire body against the side walls of the wheel rim. The tube is resilient against deflection along a line passing through both of the beads but is capable of being distorted along a line passing through the tire body toward the center of the wheel rim.

Inventors:

Charles A. Gilbert - Washington DC

International Classification:

A42B 106

US Classification:

2 10

Abstract:

Visors, for a cap or headpiece. Particularly, a focus vision visor in the form of one or more blinders which depend vertically from the visor, so as to limit peripheral vision. The blinders in the non-use storage mode may be secured to the underside of the visor.

International Classification:

B60C 700

US Classification:

152323

Abstract:

A solid, monolithic bicycle tire made of urethane rubber with a cured hardness of from 60 to 70 Durometer A. The tire is formed with a pair of laterally spaced bead shoulders that seat on the bead seats of the wheel rim, and is generally triangular in cross-section, with radially outwardly converging, slightly concave side walls that merge into a relatively narrow tread section. A circumferential, arch-shaped tunnel is formed in the inner side of the tire between the bead shoulders, and the material between the tunnel and the converging outer surfaces forms narrow, inwardly inclined side walls that are compressed when pressure is applied radially inwardly against the tread. The inclination of the side walls results in a substantial amplification of the deflection of the tire under impact loads, as compared to the deflection of similar-thickness side walls that are not inclined, but instead, are parallel to one another. As the tire is compressed under load, the side walls tend to collapse inwardly, causing the bead shoulders to grip the wheel rim with increasing force, thereby resisting any tendency of the bead shoulders to climb up over the edge of the wheel rim. The tire is also held firmly on the rim by means of a circumferential bead-locking insert that is placed in the bottom of the wheel rim before the tire is mounted.
