<p>PROBLEM TO BE SOLVED: To accumulate carriages in a shape low in volume. SOLUTION: This wheelbarrow is constituted by providing installation members 1b, 1b of a wheel in the inside of a carriage 1 formed on a rectangular outer frame 1a by square pipesproviding installation pipes 2 of the wheel of a frame shape on side surfaces of the installation members 1b by making a surface of the frame vertical to a surface of the carriage 1 and providing the frame shape on the outer frame 1a by making it vertical on the surface of the carriage 1. Contour shapes formed by projecting the leg 4, the stopper 5, the frame of the installation pipe 2 of the wheel and the square pipe of the carriage 1 on a surface vertical with the surface of the carriage 1 are respectively made a trapezoid with a part of the square pipe as a lower bottom or a triangle with the square pipe as one side and with both end angles of the side as acute angles. Each of the frames is installed on the outer frame 1a of the carriage 1 and the side surfaces of the installation members 1b of the wheel, and it is possible to accumulate the trapezoidal and triangular frame shapes as the upper ones can be fit in the lower ones.</p> |
