Patent number: 6470935Abstract: The present invention discloses a tire for a conventional rim, having two exterior sidewalls and two interior walls, and an annular tread portion with a center, an interior and an exterior surface. The first and second sidewalls extend radially from the tread portion. Each sidewall has a perimeter edge which is sized and configured to be coupled to a wheel hub. The first and second interior walls extend from substantially near the perimeter edge of the first and second sidewalls, respectively, to a predetermined location on the interior surface of the tread portion. The first and second interior walls being attached to the tread portion to transfer loads applied to the tire by alternatively flexing and compressing in response to the loads applied to the tire.Type: GrantFiled: May 2, 2000Date of Patent: October 29, 2002Assignee: Fulsang Architecture Inc.Inventor: Eric J.

Patent number: 6451142Abstract: Optics used in a high vacuum environment are mounted by bonding by use of addition polymerizing material which used in that environment. The suitability for use in the high vacuum environment is achieved by precise control of outgassing of trapped and dissolved gases, including low molecular weight hydrocarbons and amines, and unreacted material from component parts of said addition polymerizing material. A plurality of application quantities of the polymer are prepared in a large batch for use as pre-mixed frozen (PMF) material. The use of the large batch enables more precise control of mixture so that near-stoichiometric proportions of the polymer components are easily achieved.Type: GrantFiled: June 22, 2000Date of Patent: September 17, 2002Assignee: Agilent Technologies, IncInventors: Vijaya N. V. Raghavan, Mark Timothy Sullivan, Gerald William Purmal

Patent number: 5632829Abstract: A pneumatic in-line skating wheel having a tire body and central hub chemically bonded during a polyurethane casting process and further including an annularly encapsulated air bladder centrally spaced within the tire body to provide shock absorption. The bladder in one embodiment is in communication with a valve for inflation and deflation thereof such that the overall tire resiliency may be adjusted, enabling adjustable performance characteristics of the wheel. One embodiment of the valve incorporates a resilient core within a rigid barrel and stretchable to allow an inflation needle to stretch the core and drive a poppet off a seat at the interior end of the barrel.Type: GrantFiled: July 14, 1995Date of Patent: May 27, 1997Assignee: The Hyper CorporationInventors: Tom Peterson, Neal Piper

Patent number: 5265659Abstract: The relatively harsh "ride" of a non-pneumatic tire ("NPT") is greatly improved by a ring of elastomeric material referred to as a "ride-enhancing insert" ("RI"). The RI is pre-positioned on the outer surface of a wheel rim on which the NPT is to be molded of elastomeric material, most preferably a polyurethane, which is peculiarly well-suited to survive normal use on various vehicles, particularly as a replacement for a conventional spare tire, or "minispare" in an automobile. The RI is surprisingly tolerant of stress and heat loads generated by operation of the NPT/RI. The RI has a large effect on the spring rate of the NPT when deflected over a cleat, and a reduction in spring rate when deflected over a smooth laminar surface. This is of particular importance since the deflection over a cleat is where the improvement in ride is most noticeable.Type: GrantFiled: March 18, 1992Date of Patent: November 30, 1993Assignee: Uniroyal Goodrich Licensing Services, Inc.Inventors: Scott R. Pajtas, Luis G. Balderas-Ariza

Patent number: 4514243Abstract: A tire for a wheelchair wheel or the like in the form of a composite extrusion comprising a relatively soft, elastomeric casing extruded over a semirigid core. End faces of a length of extruded stock are joined by thermal fusion developed by a ferromagnetic element inserted in the tire and exposed to high frequency electromagnetic radiation.Type: GrantFiled: July 9, 1982Date of Patent: April 30, 1985Assignee: Dan T. Moore Co.Inventors: Dan T. Moore, III, Michael F. Fischer

Patent number: 4493355Abstract: Puncture-proof vehicle tires consisting essentially of one material and comprising a tread thicker than the side walls, an encircling empty space between the tread and the base of the tire and an encircling plastics reinforcement in the base of the tire.Type: GrantFiled: January 11, 1982Date of Patent: January 15, 1985Assignee: Bayer AktiengesellschaftInventors: Jakob Ippen, Friedel Stuttgen

Patent number: 4362202Abstract: A semi-pneumatic tire body for assembly to the rim of a wheel comprises spaced tread and root portions interconnected with spaced sidewalls to define an annular cavity. An annular load-bearing rib is connected to the root portion and extends radially toward the tread portion to be normally spaced apart from the tread portion in the unloaded state in order to establish communication between the internal chambers of the tire for free gaseous interchange and for free response of the tire to load forces.Type: GrantFiled: March 30, 1981Date of Patent: December 7, 1982Assignee: Sun Metal Products, Inc.Inventor: Martin B. Sacks

Patent number: 4121639Abstract: A tire and wheel construction for vehicles such as automobiles, trucks, farm equipment, etc., which includes a wheel comprised of inner and outer disc portions, bolted together in their central portions, a rim portion formed in two annular, opposed half sections from the respective disc portions, and an outwardly turned flange from the outer periphery of each rim half section. The tire comprises an inner annular wall, including opposed, annular edge projections, configurated for clamped engagement between the rim flanges, an outer annular tread wall and opposed side walls, integrally connecting between the inner and tread walls to define a completely enclosed annular chamber.Type: GrantFiled: August 15, 1977Date of Patent: October 24, 1978Inventor: Avelino Fernandez

Patent number: 3994329Abstract: A safety tire comprising a tread (11), spaced beads (12) and sidewalls connecting the beads to the sides of the tread by forming under the tread a central inflatable chamber, each sidewall comprising an outside wall convex towards the outside and an inside partition convex towards the inside delimiting between each other lateral chambers distinct from the central inflatable chamber, characterized in that said lateral chambers are filled with a flexible cellular material rendering the sidewalls suitable to support the load of the wheel with a limited sagging of the tire in case of the deflating of the central chamber.Type: GrantFiled: May 27, 1975Date of Patent: November 30, 1976Assignee: Pneumatiques, Caoutchouc Manufacture et Plastiques Kleber-ColombesInventors: Yves Masson, Jack Benard

Patent number: 3948303Abstract: A replaceable resilient tire particularly adapted for mounting on a wheel of a low velocity vehicle, such as a wheel chair, tricycle, bicycle and the like. The mounting of the tire on the rim of a wheel may be accomplished without the use of special tools, and by a person having little or no mechanical skill. The tire is of light weight, has a small transverse cross section, has good roll ability, and can be manufactured from a wide choice of extruded resilient rubber compounds or polymerized resins at a substantial saving of cost. A tensioned nylon rod of circular shape is disposed within the confines of the tire and exerts a radially directed force on the tire to maintain it in a fixed position on the rim.Type: GrantFiled: January 28, 1974Date of Patent: April 6, 1976Inventor: Ernest G.
