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.

Description

RELATED APPLICATIONS[0001]This application is a continuation in part of application Ser. No. 12 / 586,328, filed Sep. 21, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to exercise equipment, and more particularly, to heavy bags used in boxing, martial arts, athletic training, and for other athletic purposes, and in particular, to a heavy bag which incorporates features which prevents the sagging of the bag stuffing over time and use, and from flexing on its vertical axis from repeated blows or strikes to one area of the bag, and eliminates the need for an outer shell allowing for ease of shipping, assembly, and disassembly.[0004]2. Description of the Prior Art[0005]Heavy bags are generally vertical, longitudinal cylinders which are supported from a frame or from a ceiling. The bags are formed of a canvass, leather, or other suitable shell material which will stand up to punches, kicks and other athletic movement, as well as strikes ...

AI Technical Summary

Benefits of technology

[0009]An object of the present invention is to provide a novel heavy bag for athletic training in which the stuffing is modularized and supported on an internal spindle and requires no outer shell or sheathing, thereby facilitating assembly and disassembly.

[0010]Another object of the present invention is to provide for a novel heavy bag in which the stuffing or filler is modularized and supported on an internal spindle and which avoids the settling or sagging of the stuffing or filler thereby contributing to a modular heavy bag which maintains its relative density and resistance over its operating length time.

[0011]Another object of present invention is to provide for a novel heavy bag in which the stuffing or filler is modularized and supported by an internal spindle, which internal spindle being vertically oriented and stabilized at its upper end functions as a spine and minimizes side flex and shape deformation in the bag, which is caused by repeated strikes or blows to the bag in the same general area.

[0012]A still further object of the present invention is to provide for a novel modular heavy bag which may be easily assembled and disassembled.

Problems solved by technology

This presents a drawback to the athlete in training in that the density of the bag now varies such that punches and kicks delivered to one elevation of the bag may experience unpredictable density levels.

This affects the athlete's training and may also contribute to injury since the athlete through experience expects to encounter a known resistance at different levels of the bag which the sagging of the stuffing and filler disrupts.
