ABSTRACT:
The stowable shelf bag cart of the present invention includes a base portion resting on a wheeled chassis. The base portion includes a fixed lower shelf. A frame extends upwardly from the base portion, and includes four upright corner members connected at their upper ends by four lateral braces. The two ends of the cart are enclosed by end walls and a cover extends over the top of the cart. A stowable shelf is placed approximately halfway between the base and the top of the frame. The shelf includes axial projections at both ends that glide within a track fixed to each end wall. One other projection is located at each of the four corners of the stowable shelf. These projections are slidably received in tracks that are integral with the four upright corner members above the level of the stowable shelf. Latches are provided that securely lock the stowable shelf in the shelf position, yet permit the shelf to be easily adjusted to a right or left side wall position by one person without using any tools.
