TIRE WITH DURABLE SYNTHETIC BEADS
CROSS REFERENCE TO RELATED APPLICATIONS
This application claim the benefit of U.S. Provisional Application Serial No. 60/031,122 filed November 18, 1996.
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates generally to rubber tire beads and, more specifically, to tires beads incorporating a circular member made of a durable synthetic material in lieu of the conventionally used steel wire.
2. DESCRIPTION OF THE RELATED ART
Anyone who has ever had to replace a worn out tire has intimate knowledge of the cost associated therein. Hitting a pothole, running over debris (e.g. nails), or striking the curb just a little too hard are all instances which can lead to the sudden need to replace a tire. For many people, the cost of replacing one or more tires- is extremely burdensome on the family budget .
One of the factors leading to the high cost of tires can be found in the materials used in the construction of the tire beads. The bead of the tire is that part of the tire that holds the tire on the rim of the car. The conventional bead assembly is comprised of a group of steel wires. Rubber and fabric wraps around the steel wires to complete the bead package. The steel must have high tensile strengths to withstand the extreme forces placed on the tire and in addition be able to withstand temperatures in excess of 400 degrees Fahrenheit . It soon becomes evident that the high cost of steel used in the tire bead is a large contributor in the high cost of the tire. It is no secret that reducing the cost of all tires would greatly benefit the public and could in fact lead to many people replacing their tires at the appropriate time instead of waiting until the tires have lost essentially all of their tread. By replacing the conventional steel beads with plastic beads the total cost of the tire would decrease. There is, therefore, a need for an automobile tire having plastic beads in replace of steel beads wherein the plastic beads have the same tensile strength of steel and can withstand temperatures of 400 plus degrees Fahrenheit . The present invention provides such a device.
Tire beads have been described in the patent literature. For example, U.S. Pat. Nos. 5,201,972 issued to Brettschneider et al . on April 13, 1993, 4,823,857 issued to Orjela et al . on April 25, 1989, 5,467,807 issued to Neddenriep et al . on November 21, 1995, 5,429,168 issued to obb et al . on July 4, 1995, 5,198,050 issued to Gifford on March 30, 1993, 4,825,924 issued to Frerichs et al . on May 2, 1989, 4,817,696 issued to Janus et al . on April 4, 1989, 4,781,232 issued to Klose on November 1, 1988, German Pat. No. 1,098,840 issued on February 1961, and United Kingdom Pat. No. 2,135,253 published on August 30, 1984 all describe conventional tire beads but fail to disclose a hardened plastic tire circular member.
U.S. Pat. Nos. 4,794,967 issued to Charvet on January 3, 1989, 5,427,166 issued to Willard, Jr. on June 27, 1995, and 5,511,599 issued to Willard, Jr. on April 30, 1996 all describe especially reinforced tire beads but fail to disclose tire beads made of hardened plastic having the tensile strength of steel along with the ability to withstand temperatures in excess of 400 degrees Fahrenheit.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.
SUMMARY OF THE INVENTION
The present invention is a tire comprising a pair of opposing side walls which are circular and have an outside diameter and an inside diameter; a tread connecting the opposing side walls around the outside diameter; and a pair of opposing beads formed in the side walls by a synthetic circular member. The beads are formed by a circular member formed from a synthetic material which is able to withstand temperatures in excess of 400 degrees Fahrenheit. The circular member may have a circular, rectangular, square, triangular, or elliptical cross section. Also, the circular member may have a circular cross section with a flattened surface. Additionally, the circular member may be joined together in a plurality to form the bead.
The synthetic material used is preferably a plastic material which has a tensile strength similar to that of steel and is able to withstand temperatures in excess of 400° Fahrenheit. For example, for an automobile, the tire preferably has circular members with a tensile strength of about 900 to 2,500 Newtons per square millimeter. The synthetic material used is selected from the group consisting of a semi- crystalline plastic, a polyeitherimide plastic, a plastic having embedded glass, a plastic composition comprising polycarbonate and polyester PBT, and a polypheglene plastic. Accordingly, it is a principal object of the invention to provide a tire incorporating a plastic bead.
It is another object of the invention to provide a plastic tire bead having the tensile strength of steel .
It is a further object of the invention to provide plastic tire beads having the ability to withstand temperatures in excess of 400 degrees Fahrenheit. Still another object of the invention is to provide a plastic tire circular member having a rough outer surface which will facilitate rubber adhering to the plastic .
Yet another object of the invention is to provide a plastic bead to reduce the cost of manufacture of tires .
It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes .
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Fig. 1, the present invention, hereinafter referred to as a tire 10, comprises a pair of opposing side walls 12, a tread 14 and a pair of opposing tire beads 15, formed by the encasement of a circular member 16. Although what is shown in Fig. 1 is a cross-sectional view, tire 10 should be understood to be conventional in shape, thus opposing side walls 12 are circular and have an inside diameter 20 and an outside diameter 22. The overall profile of the side walls 12 are shaped in a manner to provide the best equilibrium curve for generating normal and lateral forces on the tire 10 during inflated running. Each of the circular members 16 are embedded within one of the side walls 12 by processes known by those skilled in the art . The circular members 16 are located near the edge of the tire defining the inside diameter 20. Fig. 1 also illustrates the tire 10 retained on a rim 24 by the beads and proximate to the area where the circular members 16 are located. Turning now to Fig. 2 of the drawings, a circular member 16 is shown having a circular cross section 30. The circular members 16 may also have an elliptical cross section. The circular members 16 are completely solid and unitary in construction. The circular members 16 are preferably molded into whole units by any suitable blow-molded injection process known to one skilled in the art of blow-mold injection.
The circular member 16 has essentially the same tensile strength as steel but is lighter and therefore less expensive. As an example, if the tire 10 is to be used for automobiles, the tensile strength of the circular members 16 must be between the range of 900 to 2,500 Newtons per square millimeters. In addition, the circular members 16 are made of a synthetic material that is able to withstand temperatures in excess of 400 degrees Fahrenheit. The circular members 16 must be able to withstand such temperature since when forming the tire 10, temperatures in excess of 400 degrees Fahrenheit are reached.
The synthetic material which make up the circular members 16 is preferably a plastic, which can be any semi-crystalline plastic. The material used can be a polyetherimide polymer such as ULTEM, which is manufactured by General Electric Polymer Plastic Division. The material used to make the circular members 16 could also be a plastic that has glass material embedded in it, such as NYLON- 6 or NYLON-12, made by General Electric Polymer Plastic Division. The synthetic material could also be a polymer made from polycarbonate and polyester PBT, such as ZENOY, manufactured by General Electric Polymer Plastic Division. In addition, the circular members 16 could be made from a plastic made of polypheglene, such as SUPEC, which is made by General Electric Polymer Plastic Division. In conventional steel tire beads, rubber and fabric wrap around the steel core to complete the bead package. The same is true with the present invention. To better facilitate the adhering of rubber and fabrics to the circular members 16, the outer surface of the circular members 16 may be grated, scratched, or coated with a course material which is able to withstand temperatures in excess of 400 degrees Fahrenheit . The outside and inside diameters of the circular members 16 may vary depending on tire size. Likewise, the circular members 16 circumference will also vary according to tire size.
Referring to Fig. 3, a flat surface 34 may be provided on the circular members 16 along the outside circumference. The flat surface 34 makes it easier for the rubber of the tire 10 to bind to the circular members 16.
Referring now to Fig. 5, the circular members 16 with the circular cross section 30 may be bundled as a plurality of circular members 16. Each individual circular member 16 is made of a synthetic material, such as those described above, that has the tensile strength of steel and can withstand temperatures in excess of 400 degrees Fahrenheit. Also, each individual circular member 16 is made of a solid construction and comes in various dimensions based on required tire 10 size.
Referring to Fig. 4, a circular member 16 is shown to have a rectangular cross section 38, which may also be a square cross section. As above, the circular members 16 are made of a synthetic material that has the tensile strength of steel and can withstand temperatures in excess of 400 degrees Fahrenheit. The circular member 16 is unitarily constructed by blow mold injection and comes in various dimensions based on required tire size. Referring to Fig. 6, the circular members 16 with the rectangular cross section 38 or square cross section may be bundled together as a plurality of circular members 16. Each individual circular member 16 made of a synthetic material that has the tensile strength of steel and can withstand temperatures in excess of 400 degrees Fahrenheit. Also, each individual circular member 16 is made of a solid construction and comes in various dimensions based on required tire size.
Referring to Fig. 7, a circular member 16 is shown to have a triangular cross section 46. As above, the circular members 16 are made of a synthetic material that has the tensile strength of steel and can withstand temperatures in excess of 400 degrees
Fahrenheit. The circular members 16 is unitarily constructed by blow mold injection and comes in various dimensions based on required tire 10 size.
Referring to Fig. 8, the circular members 16 with the triangular cross section 46 may be bundled together as a plurality of circular members 16 forming a hexagonally sided assembly. Each individual circular member 16 is made of a synthetic material that has the tensile strength of steel and can withstand temperatures in excess of 400 degrees Fahrenheit. Also, each individual circular member 16 is made of a solid construction and comes in various dimensions based on required tire 10 size.
It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
