  Tire with lip edge structureUSPTO Application #: 20060000537Title: Tire with lip edge structure Abstract: A tire with a lip edge structure comprises a tire body having an opening; two lip edges formed on two sides of the opening; two adhering portions; each lip edge having an adhering portion; a steel beam being embedded in the adhering portion for retaining the tire body; the adhering portion being an enlarged cambered portion, which protrudes at an outer portion of the tire body; two slide-proof cloths; an outer side of each adhering portion being enclosed by one of the mono-nylon slide-proof cloth. The slide-proof cloths are made of mono nylon with a rubber layer; the rubber layer has a thickness between 0.3 mm to 2.0 mm. The slide-proof cloth is interleaved by mono-nylon of 10˜50*10˜50 EPI and is interleaved by mono-nylon with each yarn being ranged from 210 Diner to 840 Diner. The lip edges are made of Kevlar Bead.

FIELD OF THE INVENTION [0001] The present invention relates to tires, and particular to a tire with a lip edge structure; wherein the adhering portions of the lip edges have outward cambered shapes so as to tightly buckle the wheel rims. A slide-proof cloth is placed upon each adhering portion so as to provide a friction force to the interface between the adhering portions and the wheel rim. BACKGROUND OF THE INVENTION [0002] In the prior art, tires can be classified as tube type (TT) and tubeless type (TL). The prior art tires are fixed to wheel rims by lip edges of the tires. In the design of lip edges, it is necessary to prevent the lip edges from sliding and releasing and the connection of the lip edges and the wheel rims must be air-tight so as to provide a safety driving to users. [0003] With reference to FIGS. 6, 7, the prior art tire lip edges are illustrated. In the prior art, each lip edge 1 has an adhering portion 2. A steel beam 3 is embedded into the adhering portion 2. Thereby, the lip edge can be firmly secured to the ear portions of the wheel rim. [0004] Referring to FIG. 7, an un-buckled adhering portion 2 is illustrated. It is illustrated that the adhering portion 14 has an angled outer side. As the adhering portion 2 is buckled with the ear portion 3, a gap is formed so that air possibly drains from the gap 7. This is especially harmful to a tubeless type tire. [0005] To improve the defect in the prior art, sealant is filled in the gap and the contact surfaces of the adhering portions and wheel rims. Or the wheel rim is shaped to match the shape of the lip edges. However, this will increase the cost. Especially, the tubeless type tire has a cost of 10 higher than that of the tube type tire. [0006] However, from FIG. 6, it is illustrated that the adhering portions can not fully adhere to the wheel rims so that the buckling effect between the lip edges and the wheel rims are not effective. This is dangerous when the bicycle with the tires drives in a high speed as the tire is released from the wheel rim. [0007] In one development, the adhering portion is textured so as to increase the friction force between the adhering portions and the wheel rims to have a preferred slide-proof effect, but this will cause that the air is vented from the gaps in the texture regions. SUMMARY OF THE INVENTION [0008] Accordingly, the primary object of the present invention is to provide a tire with a lip edge structure, wherein the adhering portions have an outward cambered shapes for tightly buckling the wheel rims. [0009] Another object of the present invention is to provide a tire with a lip edge structure, wherein a slide-proof cloth is placed upon the adhering portion so as to provide a friction force to the interface between the adhering portions and the wheel rim. [0010] A further object of the present invention is to provide a tire with a lip edge structure, wherein sealant is filled between the contact surfaces of the adhering portions and the wheel rim so that no air can vents from the tire. [0011] To improve the defect in the prior art, the present invention provides a tire with a lip edge structure which comprises a tire body having an opening; two lip edges formed on two sides of the opening; two adhering portion; each lip edge having a respectively adhering portion; a steel beam being embedded in the adhering portion for retaining the tire body; the adhering portion being an enlarged cambered portion, which protrudes at an outer portion of the tire body; two slide-proof cloths; an outer side of each adhering portion being enclosed by one of the mono-nylon slide-proof cloths. The slide-proof cloths are made of mono nylon with a rubber layer; and the rubber layer has a thickness between 0.3 mm to 0.2 mm. The slide-proof cloth is interleaved by mono-nylon of 10.about.50*10.about.50 EPI and is interleaved by mono-nylon with each yarn being ranged from 210 Diner to 840 Diner. The lip edges are made of Kevlar Bead. [0012] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 is a schematic perspective view of the tire of the present invention. [0014] FIG. 2 is a schematic cross view showing the lip edges of the present invention. [0015] FIG. 3 is a schematic cross view showing the assembly of the tire and wheel rim according to the present invention. [0016] FIG. 4 is a partial cross section view showing that the lip edge is coated with slide-proof cloth according to the present invention. [0017] FIG. 5 is a schematic cross view showing the assembly of the present invention with the wheel rim of the tire without any inner tire. [0018] FIG. 6 is a schematic cross view showing the assembly of a tire and a wheel rim in the prior art. [0019] FIG. 7 is a schematic cross view of the lip edge in the prior art.
