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. Thus, the doors can be moved and positioned by either operating the pins manually to clear the slots, and then releasing the pin for insertion within the desired slot, or they can be lifted in their entirety and then let down to position the pins in the desired slots. The base front edge also has an inwardly angled portion along the length thereof that angles up to a horizontal shoulder. The horizontal shoulder includes the first pair of the plurality of pin retaining slots. A vertical portion then rises from the level of the shoulder to the level of the main area of the cart base. This angled structure permits a third means for operating the doors, wherein they can be slammed closed. In this mode, the end of the pin rides up on the angled portion when the door is closed with sufficient force, thereby overcoming the biasing force of the spring. The pins of each door will then insert into the first slots in the shoulder area. The vertical edge prevents any further movement of the doors inwards as the pins thereof are blocked thereby.
