  • Patent number: 3977689
    Abstract: A nestable merchandise cart including a rear frame and hinged side frames which pivot outwardly until limit stops are engaged, and a movable shelf which, when in place to support a load, locks the side frames into positions generally perpendicular to the rear frame. The shelf can be raised and stored, which releases the side frames to pivot outwardly and form a tapered nest into which a like cart will fit nestingly. The side frames may be biased outwardly by springs and pivot outwardly automatically when the shelf is raised, and may also pivot inwardly against the rear frame to a collapsed position suitable for high density packing and shipment of the cart.
