This application is a continuation in part of application Ser. No. 12/586,328, filed Sep. 21, 2009.
BACKGROUND OF THE INVENTION1. Field of the Invention
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.
2. Description of the Prior Art
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 from inanimate objects.
The heavy bags are filled with a stuffing material which can vary. Normally cut up cloth, clothing or leather is used as the stuffing filler. However, it is not unusual to find heavy bags which are stuffed with sand filler, bead filler, foam, or other energy absorbent material which provide resistance, yet some flexibility to punches, kicks and other athletic movement. Typically the heavy bag shell is filled from the top with the stuffing or filler material and then drawn tight and secured to a support apparatus such as a chain, rope, ring or the like, which in turn is secured to a bracket eyebolt or frame which supports the heavy bag at a desired height above the floor.
The bag is used by boxers, martial arts practitioners, and other athletes, and as such, the bag is struck with the hands, feet, and other anatomical parts such as the knees, elbows, and the like, as well as inanimate objects such as weapons or striking instruments. Over time the typical heavy bag experiences sagging in that under the influence of the athletic forces imposed on the outer shell and gravity, the stuffing or filling has a tendency to migrate downwardly toward the bottom of the bag. 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. It is therefore desirable to create a heavy bag that avoids the sagging or settling affect, and insures that the relative density and resistance experienced by the athlete in training remains the same over time. It is also desirable to provide a degree of rigidity to the bag to minimize side flexing or shape deformation due to repeated striking in one particular area of the bag. Applicant's spindle support acts as a spine to minimize these undesired effects.
Applicant has further developed the heavy bag to eliminate the need for the outer shell. This allows for a more facile assembly and disassembly of the heavy bag by the individual and also allows for ease of shipping due to certain size and weight constraints. This improved and modified heavy bag can have particular desirability to an individual who wishes to have a heavy bag in his home for more convenient exercise and workouts.
OBJECTS OF THE INVENTIONAn 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.
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.
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.
A still further object of the present invention is to provide for a novel modular heavy bag which may be easily assembled and disassembled.
Another object of the present invention is to provide for a novel heavy bag which is modularized as to provide specific density customization for each individual cell.
SUMMARY OF THE INVENTIONA 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.
These and other objects of the present invention will become apparent, particularly when taken in light of the following illustrations wherein:
Ideally, the bag is stuffed with filing such that it presents a uniform density and uniform resistance from the top 18 of the bag to the bottom 16 of the bag when struck by a user. However, gravity dictates that the stuffing or filling material will settle such that through use, and time, the lower end 16 of the bag will have a density and resistance greater than the upper portion 18 of the bag. It should be noted that the heavy bags vary in length. Boxing specific bags are shorter since they are designated to be struck by the fists, while martial arts bags are longer to accommodate foot and knee strikes. The longer the bag, the more pronounced the affects of settling as the taller column of filler material creates even more internal pressure.
This settling affect of the heavy bag 10 could be greatly reduced by incorporating modularized segments which are individually stuffed and each module could be prevented from affecting an adjacent module thereby reducing the peak compression by providing individualized support to each modular segment. This can be accomplished with a support spindle post as illustrated in the two embodiments in
The stuffed modular toroidal drums or cells 40 (
The toroidal drum member or cell 40, when being placed on a stepped support post (see
The multiple ceiling mounts 20 illustrated in
Therefore, while the present invention has been disclosed with respect to the preferred embodiments thereof, it will be recognized by those of ordinary skill in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore manifestly intended that the invention be limited only by the claims and the equivalence thereof.
