Abstract
ABSTRACT OF THE DISCLOSURE
A mobile cart has fixed tray supports for a plurality of discrete and removable trays, the cart has a frame with a base and caster wheels and side frames with corner posts, and a top member structurally connecting the side frames; the trays each have a roll-section formed frame with a perimeter piece, an upper inward turned inverted U-shaped top flange, a lower inward turned floor pad, and a downward facing inverted U-shaped support nest on the bottom of each side of the frame; a tray floor in the frame has a support surface on the floor pads and upturned flanges of less than ninety degrees underneath the top flanges; each side frame has a rear stop peg and front stop peg extending in front respective corner posts, a tray support rail in between the stops, and a hold down peg above and spaced from the rear stop pegs; the tray fits upon the support with the nests upon the rails and the hold down pegs keep the trays in place during transit, the cart and trays are ideally suited for the transport and retailing of flowers, plants and other loose and delicate goods.
