Adjustable fluid-fillable exercise weights

Abstract

A weight container, which includes an adjustable calibrating bellow including two outer ribs and at least one inner rib; wherein the outer ribs may collapse and fold around the inner rib; a locking apparatus located adjacent to one outer rib; and a cover receiving apparatus located adjacent to the other outer rib. Further, a pair of weight containers may be connected to a crossbar to define an exercise apparatus. The weight container may further be adapted to engage a base to define a drinking apparatus.

1 . A weight container comprising:
 an adjustable calibrating bellow including two outer ribs and at least one inner rib;   wherein the outer ribs may collapse and fold around the inner rib;   a locking apparatus located adjacent to one outer rib; and   a cover receiving apparatus located adjacent to the other outer rib.   
     
     
         2 . The weight container as claimed in  claim 1  wherein the outer ribs have a larger diameter than the inner rib. 
     
     
         3 . The weight container as claimed in  claim 1  wherein the weight container is made of food grade plastics. 
     
     
         4 . The weight container as claimed in  claim 1  wherein the cover receiving apparatus is adapted to receive a drinking cap cover including a drinking valve. 
     
     
         5 . The weight container as claimed in  claim 1  wherein the locking apparatus is an abutment designed to engage a corresponding aperture. 
     
     
         6 . An exercise apparatus comprising:
 a pair of weight containers; and   a crossbar for connecting the two weight containers;   wherein each of the weight containers includes an adjustable calibratable cylindrical bellow and a locking apparatus adapted to engage the crossbar.   
     
     
         7 . The exercise apparatus as claimed in  claim 6  wherein the crossbar contains a mating plate designed to engage the locking apparatus of the weight container. 
     
     
         8 . The exercise apparatus as claimed in  claim 6  wherein the bellow includes two outer ribs and at least one inner rib; wherein the outer ribs may collapse and fold around the inner rib. 
     
     
         9 . The exercise apparatus as claimed in  claim 7  wherein the outer ribs have a larger diameter than the inner rib. 
     
     
         10 . The exercise apparatus as claimed in  claim 6  wherein the weight container is made of food grade plastics. 
     
     
         11 . The exercise apparatus as claimed in  claim 6  wherein the exercise apparatus further comprises a cover designed to engage a cover receiving means of the weight container. 
     
     
         12 . The exercise apparatus as claimed in  claim 11  wherein the cover is a drinking cap cover including a drinking valve. 
     
     
         13 . A drinking apparatus comprising;
 a weight container; and   a base;   wherein the weight container includes an adjustable calibrating cylindrical bellow and a locking apparatus adapted to engage the base.
