Tennis racket having filler therein

Abstract

A tennis racket includes a tubular body and a bridge member. The tubular body has a first tubular member and a second tubular member. The first and second tubular members each have a grip portion, a neck portion, and a frame portion. The interior of the tubular body is divided into a first chamber, a second chamber, and a central chamber by two partition walls disposed in the tubular body. Two fillers are disposed in the first and second chambers respectively. The bridge member is a solid structure connected with the two frame portions of the tubular body. By means of the aforesaid arrangement, the structural strength of the tennis racket is enhanced, and the shock-absorbing effect is provided by the fillers.

What is claimed is: 
     
         1 . A tennis racket defining an imaginary central axis and comprising:
 a tubular body having a first tubular member and a second tubular member, said first and second tubular members being connected integrally with each other and located at two sides of said central axis, said first tubular member having a first grip portion, a first frame portion, and a first neck portion having two opposite ends thereof connected integrally with said first grip portion and said first frame portion respectively, said second tubular member having a second grip portion, a second frame portion, and a second neck portion having two opposite ends thereof connected integrally with said second grip portion and said second frame portion respectively, said first and second grip portions both extending along said central axis and connected with each other, an end of said first frame portion located opposite to said first grip portion being connected with an end of said second frame portion located opposite to said second grip portion; and   a bridge member having two opposite ends thereof connected with said first and second frame portions respectively;   wherein said tubular body has an outer periphery wall, an inner periphery wall, a first partition wall connected between said outer periphery wall and said inner periphery wall, and a second partition wall connected between said outer periphery wall and said inner periphery wall, such that an interior of said tubular body is divided into a central chamber, a first chamber, and a second chamber;   wherein said first and second chambers are located at two opposite sides of said central chamber, and two fillers are disposed in said first and second chambers respectively.   
     
     
         2 . The tennis racket as claimed in  claim 1 , wherein said bridge member is a solid structure. 
     
     
         3 . The tennis racket as claimed in  claim 1 , wherein said first and second grip portions are spaced from each other and combined together by a connecting strip in such a way that a gap is formed between said first and second grip portions. 
     
     
         4 . The tennis racket as claimed in  claim 3 , wherein said connecting strip is a stepped structure with a first section and second section; said first section is closer to said first and second neck portions than said second section; said first section is connected with an entire surface of said inner periphery wall of said first grip portion and an entire surface of said inner periphery wall of said second grip portion, and said second section is connected with a partial surface of said inner periphery wall of said first grip portion and a partial surface of said inner periphery wall of said second grip portion. 
     
     
         5 . The tennis racket as claimed in  claim 4 , wherein an outer surface of said first section is flushed with outer surfaces of said first and second neck portions. 
     
     
         6 . The tennis racket as claimed in  claim 1 , wherein said inner periphery wall of said first grip portion is directly connected with said inner periphery wall of said second grip portion.
