    Abstract: A utility cart is an apparatus that allows a user to easily carry and access items which are placed inside of the utility car. The utility cart includes a carriage, a base, and a wheel assembly. The carriage further includes a plurality of elongated supports and a closed-shape frame. The plurality of elongated supports and the closed-shape frame define a funnel-like structural shape of the carriage which allows a user to easily access items which are placed inside of the utility cart. The base provides a structural foundation for the utility cart and the wheel assembly is integrated into the base. The wheel assembly provides a conveyance means which allows the utility cart to be translated along the ground or other surface.
