Heavy duty fitness equipment bag

Abstract

A weighted exercise device includes an inner bag for filler content containment; and an outer bag, wherein the inner and outer bags have a reinforced double closure to eliminate leaking, bursting, migration or seepage of filler content.

AI Technical Summary

Benefits of technology

[0013]In one aspect, a weighted exercise device includes an inner bag for filler content containment; and an outer bag, wherein the inner and outer bags have a reinforced double closure to eliminate leaking, bursting, migration or seepage of filler content.

[0014]In another aspect, one embodiment of the invention consists of two bags, an inner bag for sand containment and an outer bag with handles and other attributes employed in numerous exercises. The inner bag consists of a industrial strength material (though not necessarily limited to nylon) sewn and taped for the containment of sand. The outer bag is a stronger, more durable material including novel handles for exercise manipulation by the exercising user. The unique handle fabrication is ergonomically designed and padded for user comfort and safety. Both the inner and outer bags have double-secure, continuously covered closures to eliminate leaking, bursting or any unwelcome migration or seepage of filler contents. Moreover, the novel environmentally clean fill system disclosed herein establishes a manageable and secure bag filling process. The clean fill system allows the user to fill the inner bag with a flat funnel type structure that attaches to the inner bag during the filling process.

Problems solved by technology

Duffle bags are awkward to use in weight training and have limited range of manipulative motion since they only have one handle.

Obviously duffle bags were not intended for weight training.

A common problem with the type of exercise bag just described is that a substantial amount sand may leak out of the inner bag as well as the PVC bag when the exercise bag is thrown about or used as a weight lifting device.

Another problem is that the straps, being standard polypropylene webbing typically about 1½″ wide, are difficult to grip.

Strap edges may bring about injuries to the hands such as cuts and blisters.

Long term use is difficult without wearing gloves.

Generally speaking, known “fill-able” exercise bags are unpleasantly stiff and difficult to handle.

As a consequence of various shortcomings of the nature just explained, initially popular, fill-able exercise bags fell out of use fairly quickly and, in fact, are believed no longer available in the marketplace.

Bags of the USB type just referenced also tend to leak or slowly lose sand or other filler.

As with the earlier described Woody Bag™ the latter type bag has employed the same, unsatisfactory strap construction.

It, too, cuts into the hand and fingers causing discomfort and difficulty of use.

Common stitching of this sort is not adequately durable to withstand rapidly accelerated movements and impacts typical of exercise bag use.

Besides, weak stitching renders the bags vulnerable to breakage.

Exercise bags of the multi-inner bag type just described have been found awkward to use when loosely filled only with a single liner.

Like other known structures this flap presents a challenge to secure gripping and is often found more difficult to use than a webbing strap.

Durability of the double-backed flap construction is found to be inferior to a webbing strap.

The poor product construction and durability of pre-existing exercise bags has driven many gyms and users away from their use even though such bags could be used with a superior fitness regimen.

The popular demand for bag devices, more specifically sandbag or other flexibly weighted bags in aggressive training regimens has resulted in the introduction of a series of failure prone products.

Multiple problems face the exercising consumer: faulty or weak fabrication, bag leakage, inferior grip designs resulting in grip failure and / or hand injuries.

Even the supposedly simple activity of filling the exercise bag can be a messy process and difficult to manage without experiencing sand (or filler substance) overflowing into the environment.

All told, end users increasingly complain about the problems seemingly inherent in the use of sand-filled exercise bags.

Gym management personnel also complain of untidiness and maintenance demands due to bag leakage, handle grip injuries and breakage, and slippery floors brought about by spilled sand.
