Exercise tool and weight member thereof

Abstract

A weight member for exercise includes a resilient shell that defines an inner chamber. The inner chamber contains a filling having weighting and shock-absorbing properties. The filling includes a high specific weight material and one of a foamable low specific weight material and a non-foamable low specific weight material. An exercise tool including a handle and at least one weight member attached to the handle is also disclosed.

1 . A weight member for exercise comprising a resilient shell that defines an inner chamber, said inner chamber containing a filling that has weighting and shock-absorbing properties. 
   
   
       2 . The weight member of  claim 1 , wherein said filling includes a high specific weight material and one of a foamable low specific weight material and a non-foamable low specific weight material. 
   
   
       3 . The weight member of  claim 1 , wherein said filling is formed from a mixture of high specific weight granules and low specific weight granules. 
   
   
       4 . The weight member of  claim 3 , wherein said shell is formed with a hole in spatial communication with said inner chamber for introducing said filling into said inner chamber, said weight member further comprising a stopper for closing said hole. 
   
   
       5 . The weight member of  claim 4 , wherein said stopper is formed with an air inflation hole that permits charging of air into said inner chamber. 
   
   
       6 . The weight member of  claim 1 , wherein said shell is provided with an air inflation hole that permits charging of air into said inner chamber. 
   
   
       7 . The weight member of  claim 1 , wherein said shell is formed with a handle coupling hole that is spatially isolated from said inner chamber and that is adapted for extension of a handle therethrough. 
   
   
       8 . The weight member of  claim 7 , further comprising a rigid inner ring fitted in said handle coupling hole and adapted for extension of the handle therethrough. 
   
   
       9 . The weight member of  claim 1 , wherein said shell is formed with at least one finger hole that is spatially isolated from said inner chamber. 
   
   
       10 . An exercise tool, comprising:
 a handle; and   at least one weight member for exercise, said weight member including a resilient shell that is attached to said handle and that defines an inner chamber, said inner chamber containing a filling having weighting and shock-absorbing properties.   
   
   
       11 . The exercise tool of  claim 10 , wherein said filling includes a high specific weight material and one of a foamable low specific weight material and a non-foamable low specific weight material. 
   
   
       12 . The exercise tool of  claim 10 , wherein said filling is formed from a mixture of high specific weight granules and low specific weight granules. 
   
   
       13 . The exercise tool of  claim 12 , wherein said shell is formed with a hole in spatial communication with said inner chamber for introducing said filling into said inner chamber, said exercise tool further comprising a stopper for closing said hole. 
   
   
       14 . The exercise tool of  claim 13 , wherein said stopper is formed with an air inflation hole that permits charging of air into said inner chamber. 
   
   
       15 . The exercise tool of  claim 10 , wherein said shell has a tubular extension that defines a hole in spatial communication with said inner chamber for introducing said filling into said inner chamber, said handle having one end inserted fittingly into said tubular extension. 
   
   
       16 . The exercise tool of  claim 10 , wherein said handle is connected integrally to said shell. 
   
   
       17 . The exercise tool of  claim 10 , wherein said weight member further includes a coupling seat secured to said shell and fastened to one end of said handle. 
   
   
       18 . The exercise tool of  claim 17 , wherein said coupling seat is formed with a radial pin hole and permits extension of said one end of said handle therein, said handle being provided with a spring-loaded pin mechanism to engage said pin hole. 
   
   
       19 . The exercise tool of  claim 17 , wherein said coupling seat and said shell are formed with a hole in spatial communication with said inner chamber for introducing said filling into said inner chamber. 
   
   
       20 . The exercise tool of  claim 10 , wherein said shell is formed with a handle coupling hole that is spatially isolated from said inner chamber and that permits extension of said handle therethrough. 
   
   
       21 . The exercise tool of  claim 20 , wherein said weight member further includes a rigid inner ring fitted in said handle coupling hole, said handle extending through said inner ring. 
   
   
       22 . The exercise tool of  claim 10 , comprising two of said weight members attached to opposite ends of said handle. 
   
   
       23 . The exercise tool of  claim 10 , wherein said handle has opposite ends secured to said shell of said weight member.
