Abstract:
1. A foldable galley cart, comprising: first and second frames, each frame comprising: first and second primary frame members each having a first and second distal end; first and second secondary frame members each having a first and second distal end; a primary hinge pivotally connecting the respective first distal ends of the first and second primary frame members; a first secondary hinge pivotally connecting the second distal end of the first secondary frame member to a midpoint of the first primary frame member; a second secondary hinge pivotally connecting the second distal end of the second secondary frame member to a midpoint of the second primary frame member; the cart further comprising a flexible material attached to and carried by the first and second frames that forms a generally rectangular-shaped, open-topped bin when the frame is in an expanded configuration; one or more stiffening elements extending around a top perimeter of the bin and being connected to the first distal ends of the respective primary and secondary frame members of the first and second frames for stiffening the bin and improving its weight bearing capability; at least one set of wheels rotatably attached to the first and second frames; and a handle attached to the first and second frames; wherein the one or more stiffening elements comprise at least a first and second stiffening element, the first and second stiffening elements being configured to be substantially parallel to each other when the cart is in the expanded configuration; the first and second stiffening elements being further configured to pivot downwardly toward each other about at least one of the primary hinges when the cart is being converted from the expanded configuration to a collapsed configuration; and the first and second stiffening elements being configured to substantially retain their shape when in the collapsed configuration.
