Adjustable weight workout stone

Abstract

A fabricated workout stone to provide an easily assembled and transportable equivalent of a solid cast concrete spherical stone. The fabricated steel stone includes a two-part shell body with a weight receiving rod extending inside from one shell part. A threaded opening in the free end of the rod receives a retaining bolt extending through the opposite shell securing the spherical shells together. Multiple weight lifting bar weights of varied sizes and mass are slidably secured on the rod to vary the total weight of the fabricated stone when assembled for use.

1 . A weight adjustable workout sphere comprising,
 a hollow sphere having a top shell half portion and a bottom shell half portion,   a weight receiving rod secured inside the bottom shell portion and extending inside the top shell portion when joined together,   a plurality of weight retainment spacer rings slidably positioned on the weight retainment rod,   a plurality of weights having a rod hole there within stacked on said weight retainment rod between said retainment spacer rings,   a pair of resilient spacers rings on said weight retaining rod between said respective retainment spacer rings and said weights,   a threaded attachment bolt extending through an aligned opening in the upper shell half portion registerable threadably within the free end of said weight receiving rod securing the top shell half portion to said bottom shell half portion.   
     
     
         2 . The weight adjustable workout sphere set forth in  claim 1  wherein said inner sides of said top and bottom shell half portions have multiple reinforcing ribs extending radially thereon. 
     
     
         3 . The weight adjustable workout sphere set forth in  claim 1  wherein said top and bottom shell half portions have aligned apertured rod receiving fittings secured respectively there within. 
     
     
         4 . The weight adjustable workout sphere set forth in  claim 1  wherein bottom shell half portion respective free edge has a shell adjoining alignment band disposed around and extending beyond said free edge of said shell half portions defining a retainment lip. 
     
     
         5 . The weight adjustable workout sphere set forth in  claim 1  wherein said weight retainment spacer rings are of varied dimensional thickness. 
     
     
         6 . The weight adjustable workout sphere set forth in  claim 2  wherein said multiple radially attached reinforcing ribs further comprise, a contoured notched upper surface. 
     
     
         7 . The weight adjustable workout sphere set forth in  claim 3  wherein said threaded attachment bolt is keyed and extends through and retained by said top shell half portion rod receiving fitting. 
     
     
         8 . The weight adjustable workout sphere set forth in  claim 3  wherein said rod receiving fittings are secured within said respective top and bottom shell half portions by welding. 
     
     
         9 . The weight adjustable workout sphere set forth in  claim 1  wherein said weight receiving rod is secured within said bottom shell half portion by welding. 
     
     
         10 . The weight adjustable workout sphere set forth in  claim 2  wherein said multiple reinforcing ribs are secured by welding.
