ANEMO HANGER DEVICE

PROBLEM TO BE SOLVED: To secure an effective air volume and reduce noise by a method wherein an air volume, flowing from a horizontal pipe unit into a vertical pipe unit, is regulated by displacing a pair of shutter units. SOLUTION: An air volume regulating mechanism, having a pair of shutter units 5x, 5y, is arranged in a vertical pipe unit 2 while the shutter unit 5x is provided with a configuration obtained by cutting the cylinder into four equal segments through a cutting surface passing through the axial line of the cylinder and abutting surface units 5xf, 5xr, formed by bending the left-and- right end parts inwardly by a right angle, are provided. In this case, such a pair of shutter units 5x, 5y are formed so as to be capable of being displaced by sliding along the internal peripheral surface of the vertical pipe unit 2 into circumferential direction to regulate an air volume, flowing from the horizontal pipe unit 3 into the vertical pipe unit 2, through the displacement of respective shutter units 5x, 5y. According to this method, an effective air volume can be secured and the reduction of noise can be contrived.
