  • Patent number: 4887836
    Abstract: A cart with foldable side panels for transporting groceries and similar articles is shown. The cart includes a handle movable between a stowage position and an extended position for pulling the cart. A linkage couples the motion of the handle between its stowage position and its extended position to the side panels for causing the side panels to be in their folded position, resting upon the flatbed of the cart, when the handle is in its stowed position, and the side panels to be in their upstanding or erected position when the handle is in its extended position.

  • Patent number: 4878682
    Abstract: A center collapsible transport cart having at least two floor panels pivotally connected along a longitudinal pivot axis. Side panels and end members may be attached to the outer edges of the floor panel to form a desired cargo bed enclosure. When the cart is in its "operative" configuration the floor panels are horizontally disposed in approximate edge-to-edge juxtaposition. When converted to its "stowed" configuration the floor panels are generally vertically disposed in surface-to-surface juxtaposition, thereby forming a relatively flat collapsed structure. A tow bar handle is also pivotally disposable between the vertically juxtapositioned floor panels when the cart is in its stowed configuration.
