  • Patent number: 5873204
    Abstract: The present invention comprises a cart having a base and three sidewalls extending there around and upward therefrom. Four wheels are secured at bottom corners of the sidewalls to provide for easy mobility of the cart. A pair of partial doors are hingedly secured to and extend along end edges of two opposing sidewalls for permitting partial coverage of a fourth side of the cart. Each partial door includes a spring biased manually operable pin for cooperating with a plurality of slots in the cart base. In this manner the doors can be positioned from an orientation substantially coextensive with a front edge of the cart base, to positions wherein the doors are oriented inwardly of the cart loading interior space. Each door is secured to its respective sidewall in a manner wherein it can be lifted a distance sufficient to lift the pin thereof free from and above the base slots.
