Abstract
A utility cart is presented having improved assembleability, economy, rigidity and stability. In one feature, the cart includes a wheeled frame having a shelf supported by the frame. The shelf includes a movable surface and the frame includes a retention surface. The movable surface moves between a position of out of engagement with the retention surface and a position in engagement with the retention surface. This structure allows the shelf to snap into place without the need for separate mechanical fasteners. According to another feature, the cart includes a top shelf configured to deflect U-shaped leg members inward to apply a binding force upon the bottom shelf. According to a third feature, the cart includes a cross member connecting two leg members, the cross member having L-shaped slots to receive protuberances on the leg members.
