PROBLEM TO BE SOLVED: To provide a weight bag for preventing a standing signboard used at site, etc., for road works or building from being blown down. SOLUTION: A weight bag is so formed that it is developed in the shape of a square, a folding line is made in the central part, and both sides of the folding line are formed into bag sections 8. In the case the bag sections 8 are filled with sand, etc., and are opened from the folding line, since the bag sections can be easily set in feet, etc., of a signboard, weight acts on the feet of the signboard to prevent it from being blown down. Conveying efficiency is greatly promoted by attaching a string 5 used for the portable signboard to the part of the folding line. |
