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, chaize 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; andat 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. 2. The collapsible cart of claim 1, wherein, when in the deployed position, the first and second leg members cooperate to support the support member over a surface. 3. The collapsible cart of claim 1, further comprising a wheel removably coupled to the at least one hollow axle, the wheel being retained to the at least one hollow axle when the pin is inserted into aperture in the distal end of the axle. 4. The collapsible cart of claim 1, wherein the coupling assembly further comprises: a stop member coupled to the proximal end of the tether, the stop member being sized larger than the diameter of the hollow member. 5. The collapsible cart of claim 1, wherein the support member comprises a frame and supporting material coupled to the frame. 6. The collapsible cart of claim 1, further comprises a back member pivotally coupled to the support member, the back member including a frame and supporting material coupled to the frame. 7. The collapsible cart of claim 6, wherein the seatback member frame is pivotable from a stowed position, in which the seatback member is oriented generally parallel to the support member, to a deployed position, in which the seatback member is oriented non-parallel to the support member.
