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. |

1. A collapsible cart comprising:
a support member defining a support surface configured to support an object; a first leg member pivotally coupled to the support member, the first leg member pivoting from a stowed position to a deployed position; a second leg member pivotally coupled to the support member, the second leg member pivoting from a stowed position to a deployed position; and at least one coupling assembly including:
at least one hollow axle coupled to the second leg member, the at least one 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, anda pin coupled to the distal end of the tether and configured to be inserted into the aperture in the distal end of the axle. |
