Abstract

PURPOSE:In a ventilator for regulating the blowing, to reduce the depth of dimension by stretching a string section between a pair of rings arranged while facing against the wind to form a shutter while squeezing the wind path through the relative motion of ring. CONSTITUTION:A louver 17 is engaged with a projection 12B then rotated to rotate a ring 12, and the ring 12 moves obliquely back and fro along a groove 12A thereby a string member 13 is twisted or released between the rings 11, 12 without loosening the string member 13. Consequently when the string member 13 is twisted the vent area is reduced, while when it is released the ventilation is regulated. With such structure, the open face of an unit case is enlarged while the depth is reduced to regulate the flow reliably.

。FIG. 2 is a companion diagram for explaining the principle of the shutter in the present invention. A shutter is constructed by densely arranging thread-like members 10 between a pair of rings 8 and 9 arranged in the same direction in the wind blowing direction. - Ten thousand ring 8 is fixed and the other ring 9
By rotating the shutter in the circumferential direction as shown by arrows A or B, the shutter can be moved from the state shown at S in the figure to S! Adjust the ventilation opening area by changing the state shown in . The relationship between the rotational angle θ of the ring 90, the distance between the rings 8 and 9, the amount of ventilation R and the amount of ventilation Q is shown in the figure.

り量調整できる。FIG. 3 shows a complete embodiment of the invention. The shutter is made up of thread-like members 13 that are closely arranged along the curved surface formed by the rings 11 and 12. The ring 11 and the member 13 are inserted into the duct 14, and the grooves 11 on the outer circumferential surface of the ring 11 are inserted into the shutter.
Part A is tightened and fixed from the outside of the duct with a stopper 15. The shutter ring 12 has approximately the same length as the cylindrical case 16, and has oblique grooves 12A'i on its outer peripheral surface.
The groove 12A is engaged with a guide pin 16A provided on the inner peripheral surface of the case 16. Therefore, when the ring 12 rotates, the ring 12 moves back and forth in its length direction according to the inclination of the groove 12A, and the relationship between the rotation angle θ of the shutter and the distance shown in FIG. By matching them, the amount of squeezing can be adjusted without slack in the filament member 13. In addition, pin 16A
If the groove 12At is omitted and the engagement between the ring 12 and the case 16 is made slidable, after adjusting the rotation angle of the ring 12, by pulling the ring 12 completely forward, the amount of restriction can be adjusted without loosening the thread-like member 13. .
