Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to vehicle tires and, more particularly, to a tire breaker and anti-knock arrangement, which protects the tire against piercing of external sharp objects.  
           [0003]    2. Description of the Related Art  
           [0004]    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 17˜26°. 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  
         [0005]    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 breaker and anti-knock arrangement comprises a tire, the tire having two inward lips respectively protruded from two opposite sidewalls thereof at an inner side, and a supplementary bearing structure supported inside the tire between the inward lips for enabling the driver to keep driving the car to a repair shop upon a tire explosion due to an accident. According to another aspect of the present invention, the supplementary bearing loop comprises two supplementary bearing loops each formed of a plurality of arched bearing members connected in series, a plurality of compression springs respectively connected between the arched bearing members of the supplementary bearing loops, and two annular flexible packing rings respectively fastened to the inward lips and the supplementary bearing loops.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0013]    Referring to FIG. 1, the tire  10  comprises two inward lips  101  respectively inwardly protruded from the two opposite sidewalls thereof, and reinforcing wires  101   a  embedded in the inward lips  101 . The inward lips  101  have a corrugated bottom sidewall  102 , and a plurality of locating holes  103  and plugholes  104 .  
         [0014]    Referring to FIGS. 2, 3,  3 A, and  4 , a supplementary bearing structure  2000  is mounted in the tire  10 , and then fastened with the tire  10  to a wheel rim  50 . The supplementary bearing structure  2000  comprises two supplementary bearing loops each formed of a plurality of arched bearing members  20  connected in series, a plurality of compression springs  282  respectively connected between the arched bearing members  20  of the supplementary bearing loops, and two peripherally slotted annular flexible packing rings  30  respectively fastened to the inward lips  101  and the supplementary bearing loops of the arched bearing members  20 .  
         [0015]    Referring to FIGS. 3A and 4 again, each annular flexible packing ring  30  has a corrugated inner diameter  301  fitting the corrugated bottom sidewall  102  of one inward lip  101  of the tire  10 .  
         [0016]    Referring to FIGS. 2, 3, and  4  again, the arched bearing members  20  each comprise a corrugated bottom sidewall  201  fitting the corrugated inner diameter  301  of the corresponding annular flexible packing ring  30 , a downward stop flange  202  stopped at one side of the corresponding annular flexible packing ring  30 , a screw rod  203  disposed at one end, a coupling lug  204  disposed at the other end and defining a coupling hole  204   a , which receives the screw rod  203  of another arched bearing members  20 , a plurality of plug rods  207  and locating rods  205   a  and  206   a  respectively press-fitted into corresponding plugholes  104  and locating holes  103  in the inward lips  101  of the tire  10 , and coupling tubes  205   a  or  206   a . The coupling tubes  205  of the arched bearing members  20  of one supplementary bearing loop each have a longitudinal series of hook holes  205   c . The coupling tubes  206  of the arched bearing members  20  of the other supplementary bearing loop each have a hook  206   c . The coupling tubes  206  of the arched bearing members  20  of one supplementary bearing loop are respectively inserted into the coupling tubes  205  of the arched bearing members  20  of the other supplementary bearing loop, enabling the hooks  206   c  to be selectively hooked in the hook holes  205   c . The compression springs  208  are respectively mounted in the coupling tubes  206  of the arched bearing members  20  of one supplementary bearing loop and the coupling tubes  205  of the arched bearing members  20  of the other supplementary bearing loop.  
         [0017]    In case the tire  10  exploded due to an accident, the supplementary bearing structure  200  supports the tire  10  in shape, enabling the car to be continuously driven to the repair shop safely to receive a repair.  
         [0018]    [0018]FIGS. 5 and 6 show an alternate form of the present invention. According to this embodiment, the inward lips  101  of the tire  10  are made relatively thicker than the aforesaid first embodiment of the present invention, and the aforesaid flexible annular packing rings  30  are eliminated.  
         [0019]    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.
