Abstract

A wheeled utility cart includes a rigid rectangular basket component formed of molded plastic or a wire basket weave configuration. The wheels are relatively large, to permit use of the cart on rough, soft, and/or uneven surfaces, unlike the conventional small diameter casters provided on shopping carts. The wheels support the cart at a convenient height and the front and rear wheels are independently and automatically retractable, to permit the cart to be inserted into the back of a motor vehicle, such as a van, station wagon, or sport utility vehicle having a back door or gate. Lockable brakes are also provided for at least the rear wheels, to prevent the cart from rolling on a slope. The brake operation is by means of a high mounted lever, to preclude operation or disengagement by small children. A track is provided beneath the cart, which engages a mating track installed in the rear floor of the vehicle. The cart may thus be securely but removably anchored within the vehicle, for transport from store to home or other destinations as desired. Removable child seating and inner liner, as well as a cover which may be secured over the basket, are also provided for further utility. Thus, the cart may be loaded into the owner'"'"'s vehicle, transported to the store or other area, used by the owner for shopping, and loaded back into the vehicle for transport back home or to another destination as desired, by the retractable and extendible wheel mechanism.

said container portion including first and second upper rod passages and first and second lower rod passages formed respectively through said first and second lateral walls, with said lateral support means being selectively inserted through said rod passages and engaging said at least one sling seat to provide support thereto within said container portion of said cart.

8. The utility cart according to claim 1, including:

a padded upper periphery disposed about said container portion.

9. The utility cart according to claim 1, wherein:

said container portion of said cart is formed in a porous, open weave pattern.

10. The utility cart according to claim 1, wherein:

said container portion of said cart is formed of materials selected from the group consisting of plastics and metal wire.
