<p>The cart having a basket (100), including front (110), bottom (108), rear (112) and opposed rectangular side panels (104, 106), which is attached to a wheeled cart frame (101). The rear panel is pivotally attached to the upper rear portion of the basket for nesting. The lower portion of the basket is pivotally attached to the frame and is maintained in a horizontal use position by two opposed latching protrusions (206) attached to the basket and having notches (210) which engage the edges (212) of openings positioned on each side of the frame. During nesting, the basket is automatically rotated to a predetermined upper position whereby the front portion of the basket is tilted upwardly so that it can enter inside the rear portion of the next forward cart. When the latching notches are disengaged from the openings, the basket is automatically rotated upward by the force of latching springs (214) coupling the basket to the frame. A substantially U-shaped rod (202) extends horizontally along the front and side panels wherein each of its free ends is attached to the latching protrusions. A spring-loaded mechanism urges the U-shaped rod toward a forward rest position. Impact of the rod with the next forward cart during nesting results in its rearward deflection, thereby disengaging the latching protrusions from the latching edges so that the basket can be rotated upwardly to the predetermined upper position to permit nesting. </p> |
