Abstract

The tyre (10) comprises a pair of annular support members (20), each coupled respectively to or integral with a lip (101) on each side wall of the tyre (10). The annular support members (20) project into the cavity between the side walls, towards the ground engaging surface of the tyre. In use, the annular support members (20) support the ground engaging surface of the tyre when partially deflated/depressurized. Fixing of the members (20) is by adhesive and/or screws (30). The member (20) have lateral air passages (202).

Description

TIRE

BACKGROUND OF THE INVENTION

1. Field of the Invention:

The present invention relates to vehicle tires and, more particularly, to a vehicle tire, which supports the tire for normal functioning for a length time when the tire damaged accidentally.

2. Description of the Related Art:

For a safety driving, the condition of vehicle tires must be regularly checked. There are two kinds of vehicle tires used in existing motorcars, namely, the tire having an inner tube, and the tire without inner tube. According to conventional tire designs, a meshed metal wire structure formed of transverse metal wires and a longitudinal metal wires is arranged in between the carcass and the tread. The two layers of metal wires are arranged at 1726 . This meshed metal wire structure can only reinforce the structural strength of the tire. It cannot protect the tire against piercing of an external sharp object. When a nail or the like pierced through the open spaces in the meshed metal wire structure, the tire leaks, and a tire explosion accident may occur.

SUMMARY OF THE INVENTION

The present invention has been accomplished to provide a tire, which eliminates the aforesaid problems. According to one aspect of the present invention, the tire comprises a main tire 1.

-

member, the main tire member having two inward lips and transverse air holes and screw holes extended through the inward lips, two supplementary tire members respectively adhered to the inward lips of the main tire member on the inside of the main tire member, and a plurality of screws respectively threaded into the screw holes of the supplementary tire members and engaged into respective recessed holes in the inward lips. According to another aspect of the present invention, the supplementary tire members have embedded therein reinforcing steel wires and meshed reinforcing members. In an alternate form of the present invention, the supplementary tire members are respectively formed integral with the inward lips of the main tire member.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. l is an exploded view in section of the present invention.

FIG. 2 is an assembly view in sectional elevation of the present invention.

FIG. 3 is a sectional view of the present invention, showing the main tire member flattened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. from l through 3, a tire in accordance with the first embodiment of the present invention is shown comprised of a main tire member l0 and two annular supplementary l l; tire members 20 bilaterally fastened to the inside of the main tire member 10.

The main tire member 10 has embedded therein reinforcing steel wires and meshed reinforcing members (not shown), comprising two inward lips 101 respectively inwardly protruded from the two opposite sidewalls thereof and a plurality of recessed holes (not shown) in the inward lips 101.

The supplementary tire members 20 each comprise an endless groove 203 extended along one of the two opposite lateral sidewalls thereof, a plurality of transverse screw holes 201 extended through the two opposite lateral sidewalls in communication with the endless groove 203, and a plurality of transverse air holes 202 transversely extended through the two opposite lateral sidewalls for ventilation and heat dissipation.

Further, the supplementary tire members 20 each have a bottom sidewall corrugated.

Referring to FIGS. 13 again, the inward lips 101 of the main tire member 10 and the endless grooves 203 of the annular supplementary tire members 20 are covered with a layer of glue, and then the endless grooves 203 of the annular supplementary tire members 20 are respectively adhered to the inward lips 101 of the main tire member 10, and then screw 30 are respectively threaded into the screw holes 201 of the supplementary tire members 20 and 1 ' ;, 1 1 1 - ,, , engaged into the respective recessed holes in the inward lips 101 to fixedly secure the supplementary tire members 20 to the inside of the main tire member 10, and then the main tire member 10 is fastened to a wheel rim 50, forming with the wheel rim SO a vehicle tire. In case the main tire member 10 exploded due to an accident, the supplementary tire members 20 support the main tire member in shape, enabling the car to be continuously driven to the repair shop safely to receive a repair work.

It is to be understood that the drawings are designed for purposes of illustration only, and are not intended for use as a definition of the limits and scope of the invention disclosed.
