The preferred embodiment of Road and Sand Sled is comprised of at least some of the following: a board with a raised front end, pull rope holes and rails secured by slide bolts. It will also have four wheels with bearings that are attached to the axels with pressure caps
In the preferred embodiment of the invention, shown in
In order to use Road and Sand Sled, a user simply loads all of his supplies onto the board. The rails can be folded upright and secured with the slide bolts, if desired. The sled is then dragged behind a user to the destination.
The components of Road and Sand Sled may vary widely but will likely include plastic, metal and other components. The metals would ideally be selected from available steel or alloys of steel and aluminum. The production process related to the use of these metals insures that the metal is non-corrosive, durable and strong. The selected metal should have high impact strength and be capable of accepting and retaining coloring materials for an extended length of time.
The plastic used in the production will ideally be selected for durability and longevity. Thermoplastics are commonly used in the manufacturing of components similar to those used in this invention. Polyethylene, polypropylene, and other similar thermoplastic materials would be among those with the necessary traits. Members of this family are recognized universally as being versatile and of high quality.
The plastic components of Road and Sand Sled can also be formed with the use of plastic molding techniques, such as injection molding or blow molding. Injection molding requires melted plastic to be forcefully injected into relatively cool molds. As the plastic begins to harden, it takes on the shape of the mold cavity. This technique is ideal for the mass production of products. Alternatively, blow molding, a form of extrusion, could be utilized. Blow molding involves a molten tube being pushed into a mold. Compressed air then forces the molten tube against the cold walls of the mold.
It should be obvious that the board and other components of the present invention can be of various shapes and sizes. The preferred embodiment of the board is approximately fifty inches in length, thirty inches in width and four inches in thickness. The preferred embodiment of this invention has wheels with six-inch diameters. The rails are approximately six inches in height and extend approximately the length of the back and sides of the board.
It should also be obvious that the components of the invention can be made of various types of plastics or other suitable materials and can be of any color. For example, the board and wheels could be made of metal instead of plastic and the rails could be made of plastic instead of metal. While the current invention is discussed with regard to its usefulness on beaches, it should be obvious that the Road and Sand Sled could be utilized in any setting, indoor or outdoors.
It will be recognized by those skilled in the art that changes or modifications may be made to the above-described embodiments without departing from the broad inventive concepts of the invention. It should therefore be understood that this invention is not limited to the particular embodiments described herein, but is intended to include all changes and modifications that are within the scope and spirit of the invention as set forth in the claims.
