Abstract:
A three-wheeled cart includes a bottom portion with a base inclined downwardly toward a rear end of the cart, a pair of side walls attached to the base, the base and side walls defining a cavity therebetween. The bottom portion can have a pair of wedge-shaped fenders extending generally perpendicular to the side walls and a pair of axle mounts attached to the side walls and extending below the base, each side wall, fender and axle mount being integral with each other and part of a monolithic piece. A pair of front wheels is coupled via an axle to the axle mounts, the front wheels disposed below the fenders and inwardly therefrom. The cart can have a back portion attached to the bottom portion, the back portion having a back plate inclined rearwardly toward the rear end of the cart. A handle portion is attached to the side rails and has a support portion disposed rearwardly of the back plate. A rear wheel is operatively coupled to the bottom portion and disposed rearwardly of the bottom portion, the rear wheel configured to pivot about a vertical axis to facilitate the turning of the cart.
