  • Patent number: 5649718
    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.

  • Patent number: 5445399
    Abstract: A positive locking arrangement for a retractable leg of a collapsible hand truck. A slide connected to the hand truck front axle is retained within a slot formed in a tab connected to the retractable leg. The slide includes a projection interlocking the tab thereto. To disengage the locked members, the retractable leg must be swung backwardly in a first motion, thus aligning the slot with the projection. In a second motion, the slide is then raised, the projection just passing through the slot, and the slide continues to feed through the tab, coming to a final vertical position parallel to and against the hand truck body. The slide terminates at an angle, thus cooperating with the tab so as to be urged by gravity to a lowermost position, thus favoring engagement. The tab is inclined to extend upwardly from its anchoring point, thus limiting downward movement of the slide. A removable pin or hook is inserted into the slot when it is desired to secure the slide in the deployed, locked condition.
