Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates generally to a wheel rim and more particularly, to a wheel rim with tire anti-breaking anti-knocking protection.  
         [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 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 comprises a wheel rim body holding a tire, the wheel rim body having a flange extended around the periphery thereof on the middle, and a supplementary tire support mounted on the flange of the wheel rim body and adapted to support the tire in shape in case the tire is broken during running. The supplementary tire support is comprised of a plurality of joint blocks, a plurality of links that connect the joint blocks in series, and two end connecting members that join the ends of the series of joint blocks:

     DETAILED DESCRIPTION OF THE INVENTION  
       [0012]     Referring to FIGS.  1 ˜ 4 , a wheel rim with tire anti-knocking anti-breaking protection in accordance with the present invention is shown comprised of a wheel rim body  10 , and a supplementary tire support  200  mounted around the periphery of the wheel rim body  10 . The supplementary tire support  200  is comprised of a plurality of joint blocks  20 , a plurality of links  30 , a first end connecting member  40 , a second end connecting member  40   a,  and a screw bolt  50 .  
         [0013]     The wheel rim body  10  comprises a flange  101  extended around the periphery on the middle (see  FIG. 1 ). The cross section of the flange  101  can be made having any of a variety of shapes.  
         [0014]     The joint blocks  20  are hollow block members (see  FIGS. 1A and 2 ), each having a top recess  201  fixedly mounted with a packing pad  203 , and two pairs of through holes  202  axially aligned at two opposite lateral sides. The packing pad  203  has a recessed portion  204  fitting the flange  101  of the wheel rim body  10 .  
         [0015]     The links  30  connect the joint blocks  20  in series, each comprising two barrels  301  transversely disposed at two ends (see  FIG. 2 ).  
         [0016]     The first end connecting member  40  and the second end connecting member  40   a  are connected together to join the ends of the series of joint blocks  20  (see  FIG. 4 ). The first end connecting member  40  comprises a U-shaped base frame  402 , a transverse barrel  401  connected to the ends of the U-shaped base frame  402 , and a screw hole  403  extended through a middle part of the U-shaped base frame  402  (see  FIG. 3 ). The second end connecting member  40   a  comprises a U-shaped base frame  402 , two barrels  401  respectively connected to the ends of the U-shaped base frame  402 , and a through hole  403   a  extended through a middle part of the U-shaped base frame  402  (see  FIG. 3 ).  
         [0017]     The screw bolt  50  is inserted through the through hole  403   a  of the second end connecting member  40   a  and threaded into the screw hole  403  of the first end connecting member  40  to secure the first end connecting member  40  and the second end connecting member  40   a  together, having a polygonal shoulder  501  for the grasping of a wrench or the like that is used to drive the screw bolt  50  into the screw hole  403  of the first end connecting member  40  (see  FIG. 3 ).  
         [0018]     Referring to FIGS.  1 ˜ 4  again, by means of connecting the barrels  301  of the links  30  and the barrels  401  of the end connecting members  40 ; 40   a  to the through holes  202  of the joint blocks  20  with screw bolts, the rim support  200  and the joint blocks  20  with the links  30  and the end connecting members  40 ; 40   a  are fastened together, thereby forming the desired supplementary tire support  2000  around the periphery of the wheel rim body  10  within the tire  1000 .  
         [0019]     Referring to  FIG. 5 , when the tire  1000  is broken, the supplementary tire support  2000  support the broken tire  1000 , enabling the driver to drive the car to a vehicle repair shop for repair.  
         [0020]     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.
