ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a load bearing cart which is collapsible into a compact package which is light and conveniently carried. The cot may be readily reassembled.
The prior art includes U.S. Pat. No. 4,063,744 which discloses a collapsible carrier for camp packs as well as game having a single centrally located large diameter wheel and having removable handle bars which are storable within the collapsed assembly for enhanced portability. U.S. Pat. No. 4,444,405 illustrates a cart having one large centrally located wheel which has shock absorbing means as well as a mileage meter for use on rough terrain.
An important aspect of the present invention involves its use in connection with carrying game such as a deer or even larger game which has been killed in the woods and in such terrain as to be inaccessible by motorized vehicles. The task of removing large game from such terrain is generally a two-man job wherein each man carries one end of a horizontal pole from which the animal is suspended. Game carriers have been provided having some limited collapsibility but generally being of a type configured in such a manner as a hand cart with relatively larger wheels. Carts with a single wheel at one end as well as sleds have also been utilized for this purpose.
The devices of the prior art have been relatively ineffective in providing a practical means for transporting large game as a one man operation. The single wheeled devices are difficult to balance and are bulky when an attempt is made to carry them and are relatively of expensive construction. Such devices are generally incapable of utilization for any other purpose except transport of game or camping equipment. A more versatile device which is light and collapsible into a suitable package may be useful in lieu of the hand carts wherein wheels are fixed adjacent a lower corner, and wherein inexpensive means may be used for transporting loads such as layers of sod, sacks of grain, vegetables or construction materials including concrete blocks and the like.
The invention further contemplates provision of a removable brace for stabilizing the wheels and their mountings to facilitate transporting a load on the cart. Both rigid and flexible load bearing supports may be utilized and by removing the brace and providing a flexible support a recliner may be provided for the user such as a beach chair. Other beach equipment may be transported by the cart before its conversion as to a beach chair.
SUMMARY OF THE INVENTION
Accordingly, it is an important object of this invention to provide an assembly which is portable fitting into relatively close quarters and being light weight as may be readily assembled by one person for carrying game or other loads including camping equipment and the like.
Another object of the invention is to provide an all purpose cart which may be inexpensively manufactured and readily assembled and disassembled.
Another important object of the invention is to provide a collapsible cart constructed of light weight material preferably such as plastic or aluminum having a telescopic handle carried by a horizontal body having wheels carried by brackets for folding into side by side relation on the body and yet being adjustable for positioning in a generally central location in respect to the load in transversely aligned relation for bearing a load.
It has been found that a useful portable cart assembly may be provided utilizing light weight tubular structural members which may be round or square in cross-section for constructing a body having sides carrying a handle in telescopic relation thereto and which has wheel carrying brackets for longitudinal movement on the body and which are folded upwardly positioning the wheels in side by side relation for enhancing the portability of the assembly.
Another important object of the invention is the provision of a removable brace for stabilizing the wheels and their brackets during transporting of a load. A flexible or rigid support may be utilized for carrying a variety of loads without interfering with assembly and disassembly of the cart.
