  • Patent number: 4601479
    Abstract: A combination shopping cart and stock cart that includes a wheeled chassis providing a carton-carrying platform; a pair of generally vertical upright support posts at the rear of the chassis; an inverted, U-shaped, generally vertical support member the bight of which comprises a horizontal cross support member located forward of the upright support posts; and a generally horizontal side support member on each side of the cart connecting the upright support posts with the outer ends of the bight of the inverted U-shaped support member to provide a side support frame on each side of the cart. A cantilever beam means is pivotally mounted to the two side support frames so as to pivot from a horizontal, operative position to a vertical, out-of-the-way position. In its out-of-the-way position, the cantilever beam means lies substantially entirely outside the vertical space directly above the carton-carrying platform.

  • Patent number: 4593922
    Abstract: A combination nesting stop and stabilizer bracket for use with a shopping cart having a lading-carrying basket of wire construction constructed so that one shopping cart can be telescoped within a cart of similar construction during storage of the carts. The device prevents the basket from being twisted out of shape to force the bottom portion of the hinged rear wall of the basket into the gap on either side between that bottom portion and the side walls of the basket. At the same time, it prevents the bight of the relatively heavy wire U-shaped rear rim element of the basket framework of a first cart from being forced into a gap between the bottom wires of the basket and the horizontally disposed support element at the front of the tubular elevated support frame of a second cart that is telescoped within the first cart.

  • Patent number: 4423882
    Abstract: A shopping cart with a baby seat at the rear of the cart. The front wall of the seat, against which the infant or child leans, has an upright, closed position and an open position. The width of the baby seat front wall is less than the width of the main lading-carrying basket of the shopping cart, so that it can be swung down from its upright, closed position in the forward direction, when desired, to rest on the bottom wall of the basket to increase the capacity of the shopping cart by adding the space enclosed by the side and rear walls of the baby seat. A latch holds the baby seat front wall in its upright, closed position and preferably cooperates with a lost motion hinge at the bottom of the wall, and in its preferred form includes at least one cammed latch member that slides up across a ramp or slide member to (1) move the front wall upward as it approaches its closed position, and then (2) drop the front wall down to seat it in its closed position. The latch can be released by reversing this procedure.

  • Patent number: 4298127
    Abstract: A stacking basket assembly utilizing a simplified basket construction. Each basket has a nestable base that is constructed of an array of interconnected wires into front, bottom and rear walls to provide strength, rigidity, and interlocking capabilities. Each of the baskets has removable end walls with camming ears that interlockingly and securely engage the base of the basket with minimal initial force. The end walls snap-fit into the base of the basket in a wedging action for improved stacking interlock and to avoid inadvertent disengagement.
