    摘要: The present invention concerns nestable shopping carts including a lifter mechanism allowing the rear wheels of each cart to rise when they are nested together in order to facilitate their displacements when forming a line and to limit the wear of rear wheels. The lifter system comprises the wheeled chassis of the cart having a front end section sloping downwardly from a line of junction. The chassis also comprises a rear cross-bar that may pass above the line of junction of a following similar cart. The lifter system can be easily modified to cancel its rising property in that it also comprises a height adapter removably connectable to the cross-bar for reducing, when connected to the cross-bar, the height of the bottom surface of the cross-bar causing the rear end of the chassis to lift when a following similar shopping cart is nested into the shopping cart.
