Variable weight shot put assembly

Abstract

An assembly and method for a variable weight shot put assembly. The assembly maintains its size while its total weight can be altered by the user as the user trains. The assembly includes a sphere, the shot put, which splits into at least two portions. Slugs are placed in various inner cavities located within the sphere. Slugs have different set weights and weights are placed in the inner cavities so that the sphere maintains its original center of gravity.

What is claimed is: 
     
         1 . A variable weight shot put assembly, comprising:
 a sphere having a base portion and a top portion, the sphere configured to separate between the base portion and the top portion along a mating surface;   an internal cavity located within the sphere in communication with the mating surface;   a slug located in the internal cavity; and   a fastener configured to secure the base portion and the top portion together.   
     
     
         2 . The assembly of  claim 1 , wherein the base portion and the top portion interlock along the mating surface. 
     
     
         3 . The assembly of  claim 1 , wherein the internal cavity is split between the base portion and the top portion thereby forming a base internal cavity in the base portion and a top internal cavity in the top portion. 
     
     
         4 . The assembly of  claim 3 , wherein the base internal cavity and the top internal cavity are aligned when the sphere is secured. 
     
     
         5 . The assembly of  claim 3 , wherein the base internal cavity and the top internal cavity are offset when the sphere is secured. 
     
     
         6 . The assembly of  claim 1 , further comprising:
 a slug tray located in the internal cavity.   
     
     
         7 . The assembly of  claim 6 , wherein the slug is housed within the slug tray. 
     
     
         8 . The assembly of  claim 6 , wherein the slug tray is interchangeable. 
     
     
         9 . The assembly of  claim 1 , wherein the slug is interchangeable. 
     
     
         10 . The assembly of  claim 1 , wherein the slug placement centers the center of gravity within the sphere. 
     
     
         11 . A variable weight shot put assembly, comprising:
 a sphere having a base portion and a top portion the sphere configured to separate between the base portion and the top portion along a mating surface;   a plurality of internal cavities in the base portion and in the top portion;   a plurality of slugs configured to reside in the plurality of internal cavities; and   a fastener configured to secure the base portion and the top portion together.   
     
     
         12 . The assembly of  claim 11 , wherein the plurality of internal cavities form a symmetrical pattern around a center of the sphere. 
     
     
         13 . The assembly of  claim 11 , wherein the plurality of slugs are aligned with and located in the plurality of internal cavities between both the top portion and the base portion. 
     
     
         14 . The assembly of  claim 13 , wherein the placement of the plurality of slugs within the sphere is alterable so as to adjust the pattern. 
     
     
         15 . A method for using a variable weight shot put assembly, comprising:
 opening a sphere including at least one internal cavity, the sphere configured to separate along a mating surface between a top portion and a bottom portion, the at least one internal cavity having an opening along the mating surface;   locating a one or more slugs in the at least one internal cavity;   exchanging the one or more slugs to adjust the weight within the sphere; and   securing the one or more slugs in the sphere through the use of a fastener in communication with the sphere.   
     
     
         16 . The method of  claim 15 , further comprising:
 locating the one or more slugs in a slug tray.   
     
     
         17 . The method of  claim 16 , further comprising:
 locating the slug tray in the internal cavity.   
     
     
         18 . The method of  claim 15 , further comprising:
 arranging the one or more slugs within the sphere in a selected pattern.   
     
     
         19 . The method of  claim 18 , wherein arrangement of the one or more slugs maintains a center of gravity of the sphere about a center point of the sphere. 
     
     
         20 . The method of  claim 15 , wherein each of the one or more slugs are located in a separate cavity within the at least one internal cavity.
