However, in the invention disclosed in Patent Document 1, when the air volume adjusting member is not mounted, the opening area is narrowed due to the presence of the air passage obstruction plate, the pressure loss is increased, and the air volume is reduced. In order to prevent a decrease in the amount of air, it is necessary to replace the flange member formed by a mold different from the flange member to which the air volume adjusting member is attached, or to prevent the hook from being disposed in the air volume adjusting member when the air volume adjusting member is fully opened. The gap of the interference of the sliding portion is provided on the obstruction plate. Change to different The method of forming the flange member of the mold requires replacement of the flange member each time the opening and closing operation is performed, which is not practical. Further, in the method of providing the notch to the obstruction plate, there is no means for merely blocking the notch when the air passage is to be fully closed, and the air passage cannot be fully closed. In order to make the air volume adjusting member slide to the air passage when the obstruction plate is not provided with a notch, it is necessary to make the flange outer shape twice as large as the opening. Since the flange member itself is too large, it is not practical.

The present invention has been made in view of the above, and it is an object of the present invention to provide a ventilation system component that can close an open end when an air volume adjusting member is used, but suppresses the air volume adjusting member without being installed. The area of the opening at the open end is reduced, and the common components can be applied regardless of the presence or absence of the air volume adjusting member.

In order to solve the above problems and achieve the object, the present invention is a ventilation system component provided in a ventilation passage, comprising: a flange member including: a cylindrical connecting tubular portion; and a flange portion connected from the flange One end portion of the tubular portion protrudes in a square shape in the diameter increasing direction; and the guide rail is traversed at an opening end of one end side of the connecting tubular portion in a diagonal direction of the flange portion; the lattice plate member is detachably mounted The front surface of the flange member and the pair of semicircular air volume adjusting members are slid on the guide rail and moved between a first position in which the opening end is opened and a second position in which the opening end is closed, and are disposed in the second position. A circular shape is formed at the position.

According to the present invention, there is an effect that a system member for ventilation can be obtained, and the system member for ventilation can close the open end when the air volume adjusting member is used, but the opening end can be suppressed without installing the air volume adjusting member. The area of the opening is reduced, and the common components can be applied with or without the air volume adjusting member.

Fig. 8 is a front elevational view showing a state in which the air volume adjusting member of the ventilation terminator of the embodiment is closed at the open end, with the lattice plate member omitted. 9th A front view of the ventilating terminal of the embodiment of the embodiment is omitted, and the air flow adjusting member is omitted. The recess 16 is provided around the open end 13. A flat plate-shaped guide rail 14 that traverses the flange portion 3 in the diagonal direction is provided at the open end 13. Further, the opening end 13 is provided with a reinforcing rib 15 which is traversed in a diagonal direction different from the guide rail 14 and which is aligned with the guide rail 14 to have a cross frame structure. The front surface of the guide rail 14 and the reinforcing rib 15 is formed on the same surface as the portion corresponding to the bottom of the concave portion 16 of the flange portion 3. The recessed portion 16 on the front surface of the flange portion 3 is fitted and mounted in a semicircular air volume adjusting member 8 so as to be slidable in the diagonal direction of the flange portion 3 along the guide rail 14. The air volume adjusting member 8 is an area of about half of the area in which the recess 16 is equally divided by the reinforcing ribs 15. The two air volume adjusting members 8 are slid independently of the guide rail 14 between the first position where the open end 13 is opened and the second position where the open end 13 is closed. In the embodiment, the first position is located at the end of the guide rail 14, and the second position is located at the center of the guide rail 14. The air volume adjusting member 8 has a semicircular chord that faces each other so as to be formed in a circular shape when placed at the second position.

Fig. 10 is a front elevational view showing the air volume adjusting member of the ventilation terminator of the embodiment. Fig. 11 is a side view of the air volume adjusting member of the ventilation terminator of the embodiment. Fig. 12 is a cross-sectional view showing an air volume adjusting member of the ventilation terminator of the embodiment. Fig. 12 is a cross section taken along the line XII-XII in Fig. 10. Fig. 13 is a view showing a mounted state of the air volume adjusting member of the ventilation terminator of the embodiment. Fig. 13 is a cross section taken along the line XIII-XIII in Fig. 3. Each of the air volume adjusting members 8 is hooked to the sliding portion 17 and hung in the guide rail 14, and is prevented from coming off at the front end by a hook 18 having a wide contact area, and is attached to the guide rail 14. The hook finger portion 19 is formed in the air volume adjusting member 8, and when the air volume is adjusted, the finger is hooked to the hook finger portion 19, and the air volume adjusting member 8 can be smoothly slid. Such as As described above, since the front surface of the reinforcing rib 15 is formed on the same surface as the flange portion 3, when the air volume adjusting member 8 closes the open end 13, the air volume adjusting members 8 can be in close contact with each other, and the reinforcing rib 15 can be made thinner. It is made to inhibit the air supply performance.

As shown in FIG. 3 and FIG. 8, the display unit 20 having the opening size indicating the opening end 13 corresponding to the sliding position of the air volume adjusting member 8 is attached to the edge of the recessed portion 16 on the front surface of the flange portion 3, Each of the air volume adjusting members 8 is respectively provided with an indicator 21 which is aligned with the display unit 20, and the opening size of the opening end 13 coincides with the display unit 20.

In the case where the air volume adjusting member 8 slides along the side of the flange portion 3, even if one side of the flange portion 3 is 1.8 times the diameter of the open end 13, it is impossible to ensure sufficient coverage of the open end 13 only by the air volume adjusting member 8. area. Therefore, it is necessary to provide a flat portion having an area of 0.1 times the diameter of the open end 13 on both sides of the open end 13. When the flat portion is provided at the open end 13, when the air volume adjusting member 8 is not attached, the flat portion becomes a pressure loss, and since the air blowing performance is hindered, the supply is made common to the components. Further, in order to secure the area sufficient to cover the open end 13 by only the air volume adjusting member 8, since one side of the flange portion 3 needs to be twice the diameter of the open end 13, the size of the flange member 4 becomes large, and Increased material costs, damage to design, etc.

In the system member for ventilation of the embodiment, although one side of the flange portion 3 is 1.8 times the diameter of the open end 13, the state in which the air volume adjusting member 8 is removed as shown in Fig. 9 can be made in addition to the guide rail 14 and the reinforcing rib. Outside 15 The structure of the open end 13 is maintained. Therefore, in the ventilation terminator 1 of the embodiment, the opening end 13 can be closed when the air volume adjusting member 8 is used. However, when the air volume adjusting member 8 is not attached, the reduction of the opening area of the opening end 13 is suppressed, regardless of the installation air volume adjustment. For component 8, a common component can be applied.
