Rubber barbell weight with at least one colored rubber belt and a method of making the same

Abstract

A method of making a rubber barbell weight with as least on colored rubber belt has acts of providing at least one annular colored rubber belt, providing a mold, placing the at least one annular colored rubber belt in the mold, placing rubber raw materials in the mold, heating and pressing the mold and releasing the mold. The mold has two middle molds. Each middle mold has at least one recess formed radially in an inside wall of the mold. The annular colored rubber belt is placed into the recesses of the middle molds. The rubber raw materials are placed into the mold. Because top and bottom flanges of each recess of the middle mold limit the annular colored rubber belt only fusing with adjacent rubber raw materials, an outside surface of the annular colored rubber belt does not mix with the color of the rubber raw materials.

1 . A rubber barbell weight with at least one annular colored rubber belt comprising:
 an annular edge;   at least two recesses formed radially in the annular edge; and   at least one annular colored rubber belt, and each one of the at least one annular colored rubber belt formed between corresponding two recesses.   
   
   
       2 . The rubber barbell weight as claimed in  claim 1  having two recesses and one annular colored rubber belt. 
   
   
       3 . The rubber barbell weight as claimed in  claim 1  having three recesses and two annular colored rubber belts. 
   
   
       4 . A method of making a rubber barbell weight with at least one colored rubber belt comprising acts of:
 providing at least one annular colored rubber belt;   providing a mold, wherein the mold comprises
 a lower mold having
 a top surface; 
 a cavity formed in the top surface of the lower mold; 
 
 two middle molds attached to the top surface of the lower mold, and each middle mold being semicircular and having
 a top surface; 
 an inside wall; and 
 at least one recess, and each one of the at least one recess formed radially in the inside wall of the middle mold and having a top flange and a bottom flange; and 
 
 an upper mold is attached to the top surfaces of the middle molds and having
 a bottom surface; and 
 a cavity formed in the bottom surface of the upper mold and aligning with the cavity of the lower mold; 
 
   placing each one of the at least one annular colored rubber belt in corresponding recesses of the middle molds between corresponding top and bottom flanges;   placing rubber raw materials into the cavities of the lower and upper molds and inside the at least one annular colored rubber belt;   heating and pressing the mold; and   releasing the mold.   
   
   
       5 . The method as claimed in  claim 4 , wherein
 only one annular colored rubber belt is provided at the act of placing each one of the at least one annular colored rubber belt; and   each middle mold has one recess.   
   
   
       6 . The method as claimed in  claim 4 , wherein
 two annular colored rubber belts are provided at the act of placing each one of the at least one annular colored rubber belt; and   each middle mold has two recesses.
