Abstract
Abstract A multi purpose, manually operated carrying device, which can be utilized as a wheel barrow, a dolly or as a snow shovel. It comprises a substantially flat bottomed, trough-shaped container with two opposite side walls, and one transverse end wall, which container is adapted for a pair of wheels and provided with a pivotable handle member. The handle member and the container are mutually adapted to each other such that the handle member can be fixed to the container in a first position wherein the handle member extends along the substantially flat container bottom and making the device operative as a dolly, and in a second position wherein the handle member can be fixed to the end wall making the device operative as a wheel barrow. A snow shovel is provided upon removal of the wheels.
