Modular heavy bag with spindle support requiring no outer shell

Abstract

A heavy bag for boxing, martial arts, or other athletic practice, requiring no outer unitary sheath and having a lower support member, the lower support member having an upwardly extending spindle, there being slidably receivable on the spindle a plurality of independently stuffed modular toroidal drums or cells whose central aperture is complimentary with the diameter of the spindle, each of the stuffed modular toroidal drums or cells having independent support to prevent compression of the stuffed toroidal drums or cells the spaces between adjacent toroidal drums or cells being covered by padded hook and loop fasteners girding the toroidal drums or cells.

1 . A modular heavy bag for use in boxing, the martial arts, or other athletic exercises, the modular heavy bag comprising:
 spindle having a base member, said spindle extending vertically upwardly there from terminating in a threaded upper end;   a plurality of modular stuffed drums having a toroidal shape, each drum having a centrally disposed vertical aperture dimension corresponding to a diameter dimension of said spindle, said modular stuffed drums stacked on said spindle, each of said modular stuffed drums supported independently from said adjacent modular stuffed drum;   means for supporting said modular heavy bag.   
     
     
         2 . The modular heavy bag in accordance with  claim 1  wherein each of said modular stuffed drums are formed of a casing having a cylindrical side wall, planar upper wall, and planar lower wall, and a cylindrical inner wall thereby defining a toroidal cavity for the receipt of stuffing material. 
     
     
         3 . The modular heavy bag in accordance with  claim 2  wherein each of said modular stuffed drums has a securable opening to allow for the positioning of stuffing materials therein. 
     
     
         4 . The modular heavy bag in accordance with  claim 3  wherein said modular stuffed drums are filled with a stuffing material, said stuffing material selected from a group consisting of sand, pieces of cut cloth, clothing, gel, liquid, foam, rubber, particles or pellets of rubber and egg foam. 
     
     
         5 . The modular heavy bag in accordance with  claim 4  wherein said stuffing materials can be positioned within said drums to vary the density and hardness of the respective drums. 
     
     
         6 . The modular heavy bag in accordance with  claim 1  wherein a support means secured to said upper end of said spindle is secured to an overhead bracket, said support means providing vertical support to said spindle and to said modular stuffed drums minimizing sag of said drums and maintaining desired vertical densities within said heavy bag. 
     
     
         7 . The modular heavy bag in accordance with  claim 2  wherein a lower modular stuffed drum positioned on said spindle is supported by said base member and an upper modular stuffed drum positioned on said spindle is supported by an upper support member positioned within said upper modular stuffed drum adjacent said planar upper wall and cooperable with said means for supporting said modular heavy bag. 
     
     
         8 . The modular heavy bag in accordance with  claim 7  wherein said means for supporting said modular heavy bag comprises a plurality of flexible support members, one end of each being secured to said upper support member in said upper modular stuffed drum, and opposing ends being secured to a support bracket. 
     
     
         9 . The modular heavy bag in accordance with  claim 7  wherein said means for supporting said modular heavy bag comprises a threaded collar threadedly secured to said upper end of said spindle, said threaded collar having an aperture there through for receipt of an attachment means for hanging said heavy bag, said upper support member secured to said spindle by a flange nut and lock nut below said threaded collar. 
     
     
         10 . The modular heavy bag in accordance with  claim 2  wherein a lower modular stuffed drum is supported by said base member, said lower modular stuffed drum having positioned in its centrally disposed vertical aperture a T-shaped intermediate support member comprising an intermediate planar support positioned adjacent said outer upper planar wall of said lower modular stuffed drum, a depending support arm having a central bore slidably receivable on said spindle, said depending support arm resting on said base member, said intermediate support member supporting said upper modular stuffed drum. 
     
     
         11 . The modular heavy bag in accordance with  claim 2  wherein a delineation defined by said planar lower wall of said upper modular stuffed drum and said planar upper wall of said lower modular stuffed drum is girded by a coupling belt. 
     
     
         12 . The modular heavy bag in accordance with  claim 11  wherein said coupling belt is padded and secured about said delineation by hook and loop fasteners. 
     
     
         13 . The modular heavy bag in accordance with  claim 2  wherein a lower modular stuffed drum is supported by said base member, and wherein said spindle is stepped, having a greater lower diameter accommodating said lower modular stuffed drum and a smaller upper diameter accommodating an upper modular stuffed drum, said upper modular stuffed drum supported by an intermediate support slidably receivable on said upper portion of said spindle and supported by said lower portion of said stepped spindle.
