ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to motor vehicles steered by walking attendants.
BACKGROUND OF THE INVENTION
Carts of various sorts have been used around the home and in business settings to haul goods from one place to another. Many of these carts are of uncomplicated construction, lacking automated features and costing relatively little. Others, produced at great expense, can transport large and heavy loads with minimal human intervention. A need presently exists for a utility cart which fills a niche between these two extremes.
SUMMARY OF THE INVENTION
In light of the problems associated with the prior art, it is a principal object of the invention to provide residential and commercial users with a motorized utility cart for transporting heavy and bulky loads of minimal complexity and cost.
It is another object of the invention to provide a utility cart of the type described with motor-driven, traction wheels whose speed and direction of rotation are controlled by a walking attendant.
Still another object of the invention is to provide a utility cart with a load-carrying hopper which may be automatically elevated for dumping.
It is a further object of the invention to a utility cart with a hopper that may be readily detached from a supporting platform so that loads having dimensions large than the hopper can be carried directly upon the platform without impediment.
It is an additional object of the invention to provide a utility cart with a “three-way,” swinging gate which: pivots up, pivots down, and is removable for expedited loading and unloading its associated hopper.
It is an object of the invention to provide improved elements and arrangements thereof in a utility cart for the purposes described which is lightweight in construction, inexpensive to manufacture, and dependable in use.
Briefly, the cart in accordance with this invention achieves the intended objects by featuring a platform supported by casters and traction wheels. Atop the platform is positioned a hopper which may be lifted by a motorized dumping mechanism for dumping through a swinging gate. The hopper may be detached from the platform and lifting mechanism, if desired, by means of removable pins. Similar pins permit the gate to be operated from different positions on the hopper. A handlebar extends upwardly from the platform and supports a plurality of switches for selectively controlling the direction of electric current flow to the motors powering the wheels and dumping mechanism.
The foregoing and other objects, features and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.
