Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates generally to a motor vehicle and more particularly, to a vehicle wheel rim assembly that allows the car driver to drive the car to the car shop safety for receiving a repair work when the tire is broken.  
         [0003]     2. Description of the Related Art  
         [0004]     When the tire of a vehicle wheel is inflated, high-pressure air supports the tire in shape for running on the road. If a pointed body pierced the tire, the broken tire becomes unable to support the vehicle wheel for normal running on the road, and the broken tire must be repaired immediately. However, It is dangerous if one of the wheels of a vehicle is broken during a high speed running.  
       SUMMARY OF THE INVENTION  
       [0005]     The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a wheel rim assembly for vehicle tire, which supports the tire in shape for enabling the car to run to a repair shop in case the tire is broken during running. To achieve this and other objects of the present invention, the wheel rim assembly comprises a wheel rim body holding a tire, a mounting ring mounted on the wheel rim body, the mounting ring being comprised of two semicircular frame bars, the semicircular frame bars each having an inner mounting wall fitting the periphery of the wheel rim body, an outer mounting groove formed in an outer wall thereof, a lever-operated hook at a first end thereof, and a retaining loop at a second end thereof, the lever-operated hook of one of the semicircular frame bars being connectable to the retaining loop of the other of the semicircular frame bars, a packing rubber mounted in the outer mounting grooves of the semicircular frame bars, and a supplementary tire support mounted on the packing rubber around the mounting ring.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0019]     Referring to FIGS.  1 ˜ 9 , a wheel rim assembly in accordance with the present invention is shown comprised of a wheel rim body  60 , a mounting ring  10 , and a supplementary tire support  20 .  
         [0020]     The mounting ring  10  is comprised of two semicircular frame bars  101  and  101   a  (see  FIGS. 1 and 2 ). The semicircular frame bars  101  and  101   a  each have an inner mounting wall  104  fitting the periphery of the wheel rim body  60 , and an outer mounting groove  105  formed in the outer wall thereof and extending along the length for receiving a packing rubber  106  (see  FIG. 3 ). The semicircular frame bars  101  and  101   a  each further has a lever-operated hook  102  at one end and a retaining loop  103  at the other end. By means of fastening the lever-operated hook  102  of one semicircular frame bar  101  or  101   a  to the retaining loop  103  of the other semicircular frame bar  101   a  or  101 , the two semicircular frame bars  101  and  101   a  are connected together and fastened to the periphery of the wheel rim body  60  (see  FIGS. 8 and 9 )  
         [0021]     Referring to  FIGS. 4 through 7  again, the supplementary tire support  20  is mounted on the packing rubber  16  around the mounting ring  10 , comprised of a plurality of joint blocks  201 , a plurality of links  30 , a first end connecting member  202 , a second end connecting member  202   a , a plurality of screw bolts  40 , a plurality of elongated packing plates  41 , and a tensile spring  50 .  
         [0022]     The joint blocks  201  each have two mounting through holes  201   a  transversely extending through the two opposite lateral sidewalls thereof near the front and rear ends for mounting.  
         [0023]     The links  30  connect the joint blocks  201  in series, each comprising two mounting holes  301  transversely extending through two opposite lateral sidewalls thereof near the front and rear ends and respectively one mounting through hole  201   a  of each of two adjacent joint blocks  201 .  
         [0024]     The elongated packing plates  41  are respectively attached to the two opposite lateral sidewalls of each of the joint blocks  201 .  
         [0025]     The screw bolts  40  are respectively fastened to the two eyed-ends of the elongated packing plates  41 , the mounting through holes  201   a  of the joint blocks  201  and the mounting holes  301  of the links  30  to connect the joint blocks  201  in series.  
         [0026]     The first end connecting member  202  and the second end connecting member  202   a  are connected together to join the ends of the series of joint blocks  20  (see FIGS.  5 ˜ 7 ). The first end connecting member  202  comprises a front coupling rod  202   b , a cushion  203   a  around the root of the front coupling rod  202   b , and two hooks  202   d  symmetrically disposed at two opposite lateral sides. The second end connecting member  202   a  comprises a front coupling hole  202   c  for receiving the front coupling rod  202   b  of the first end connecting member  202 , two hangers  21  respectively pivotally provided at two opposite lateral sides thereof for hooking on the hooks  202   d  at the first end connecting member  202 , two locking levers  202   e  adapted to move the hangers  21  between the locking position and the unlocking position, and two hooks  202   g  for holding the locking levers  202   e  in the received position. Further, the end connecting member  202  or  202   a  has two recessed portions  202   f  symmetrically formed in the two opposite lateral sides corresponding to the hooks  202   d  or locking lever  202   e.    
         [0027]     The tensile spring  50  is mounted on the coupling rod  202   b  of the first end connecting member  202  and supported between the cushion  203   a  and the second end connecting member  202   a  around the coupling hole  202   c.    
         [0028]     Further, the joint blocks  201  and the end connecting members  202  and  202   a  each have an inner mounting groove  203  fitting the packing rubber  106  around the mounting ring  10 .  
         [0029]     Referring to  FIGS. 11 and 12  and  FIGS. 8 and 9  again, the tire  1000  is fastened to one side of the wheel rim body  60  at first, and then the semicircular frame bars  101  and  101   a  are inserted into the inside of the tire  1000  and joined together around the wheel rim body  60 , and then the packing rubber  106  is fastened to the outer mounting grooves  105  of the semicircular frame bars  101  and  101   a  of the mounting ring  10 , and then the first and second end connecting members  202  and  202   a  of the supplementary tire support  20  are fastened together to secure the supplementary tire support  20  to the packing rubber  106  at the mounting ring  10  around the wheel rim body  10  within the tire  1000 .  
         [0030]     Referring to  FIG. 10 , when wishing to remove the supplementary tire support  20  from the mounting ring  10  and the wheel rim body  10 , insert a screwdriver or the like into the recessed portion  202   f  to lift the respective locking lever  202   e  and hanger  21  from the respective hook  202   g  or  202   d.    
         [0031]     Referring to  FIG. 13 , when the tire  1000  is broken, the supplementary tire support  20  support the broken tire  1000 , enabling the driver to drive the car to a vehicle repair shop for repair. Further, the packing rubber  106  absorbs shocks from the supplementary tire support  20 .  
         [0032]     Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
