  • Patent number: 6139029
    Abstract: A multipurpose two-wheeled cart whose wheels are removable from the body of the cart to leave a generally planar flat bottom, so that the cart can be used as a sled. Side extensions may be mounted to hold bulky loads. Removable handles are provided at both of the sloping ends of the body and are adjustable to keep grips at the same height from the ground when the wheels are removed. Either or both of the handles may be mounted and used, depending on whether terrain and load make it desirable for one person or two people to move the cart and its load. The handles, wheels, and side extensions all fit within the body to provide a compact unit for transport in a motor vehicle. Stiffeners on the bottom of the body may be used as runners.
