Abstract
Abstract A mobile extra display cart is described. The cart includes a plurality of vertically adjustable shelves which slide in two vertical tracks located on the back wall of the cart. The plurality of vertically adjustable shelves are designed to pivot upwardly against the back of the cart when the stacked products are removed from the respective shelves. To facilitate the use of the mobile extra display cart as a delivery cart for the stacked products, each respective shelf is molded from plastic and contains an upper and lower lip to keep the stacked products from sliding off the shelves. In addition, there is provided a top cap which is adjustable in the vertical tracks and is hinged at the back of the cart. The top cap is designed to pivot downwardly covering the top layer of the stacked products and in combination with a pair of straps joined together in a Y configuration, the cap is maintained in compression with the stacked products to prevent them from falling out from between the shelves.
