Abstract
A cart includes a platform assembly, a handle assembly, first wheel assembly and a second wheel assembly. In use, the cart may folded from a deployed position in which it rolls along a surface to transport items, to a stowed position, in which it is collapsed in a compact geometry for storage. The cart may be further integrated into a chair, chaise lounge, garden cart, bicycle utility cart or a bicycle passenger cart.
Claims64
A collapsible cart comprising:
- a support assembly including:
- a seat member comprising a frame and supporting material coupled to the frame, wherein the seat member defines a seating surface configured to support an object,
- a first leg member pivotally coupled to the seat member frame, the first leg member pivoting from a stowed position to a deployed position,
- a second leg member pivotally coupled to the seat member frame, the second leg member pivoting from a stowed position to a deployed position;
- and
- at least one coupling assembly including:
- a hollow axle coupled to the second leg member, the hollow axle having a diameter, a distal end, a proximal end, a passage extending from the distal end to the proximal end through the axle, and an aperture extending through the distal end, the aperture being perpendicular to the passage,
- a tether threaded through the hollow axle, the tether having a distal end and a proximal end,
- a pin coupled to the distal end of the tether and configured to be inserted into the aperture in the distal end of the axle, and
- a stop member coupled to the proximal end of the tether, the stop member being sized larger than the diameter of the hollow member.
