The present invention relates wagons to transport general items or equipment from one location to another. More particularly, wagons that are motorized.
In general, wagons or carts are used for carrying or transporting multiple, heavy or bulky items from location to another. Wagons consists of having a cargo-hold or basket to store or carry items, wheels or tracks to traverse over various surfaces or terrains and handle(s) aid in directionally pushing or pulling the wagon to the destination. The cargo-hold or basket of the wagon commonly has a bottom section and walls or liners made of metal, wood, plastic, fabric, or combinations of materials.
Users have difficulty pulling a non-motorized and heavily loaded wagon, when traversing soft or rough terrains and elevation changes.
Folding wagons have small wheels that will bury in soft terrains such as sand or grass, or easily catch in rough or rocky terrain when the wagon is loaded with heavy items, producing a lot of pulling effort by the user.
Wagons that do not have synchronous and directional steering, such as castor wheels, are difficult to turn when the wagon is loaded with heavy items and in soft or rough terrain.
Motorized wagons in the current market are not small, portable and light enough to be stored and transported within an automobile.
Presently there is no wagon that that is portable to be stored in the trunk or inside of a car, and light and simple enough to be easily deployed, and when loaded with heavy items, have the versatility to traverse a multitude of terrains and elevations and direction with very little effort and much control by the user.
The present invention seeks to provide a solution to the problems by providing a lightweight, and motorized folding wagon that fits and can be transported in an automobile. The wagon has large wheels with treaded tires, controlled steering and controlled motor propulsion(s) and braking, to allow transport of heavy loads on a variety of terrains and elevation changes, enabling high control of the wagon and little pulling effort by the user.
Some embodiments of the present invention are illustrated as an example and are not limited by the figures of the accompanying drawings, in which like references may indicate similar elements and in which:
