により筒体の屈曲状態が次第に変つたり、あるい
は空気吹出口に他の器物が接触した際に筒体の屈
曲状態が大きく変つたりして、空気吹出方向が設
定した方向からズレ易いという問題があつた。 However, these devices do not have a means for fixedly positioning the cylindrical body in a specific bent state, that is, in a state in which air is blown out in a specific direction. The bending state of the cylinder may gradually change due to the outlet's own weight, or the bending state of the cylinder may change significantly when another object comes into contact with the air outlet, causing the air blowing direction to change from the set direction. I had a problem with it slipping easily.
また逆に、空気吹出方向を若干変更したい場合
でも、空気吹出口全体の向きを変えなければなら
ないため、大型の空調装置にあつては特に、その
手間と労力が馬鹿にならなかつた。 On the other hand, even if it is desired to slightly change the air blowing direction, the direction of the entire air blowing outlet must be changed, which requires considerable time and effort, especially in the case of large air conditioners.
そこで本考案は、空気吹出口を特定の空気吹出
方向において固定的に位置決めでき、かつ一定の
範囲内であればその空気吹出方向を簡易に変更で
きるようにすることを目的とする。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to enable fixed positioning of an air outlet in a specific air blowing direction, and to easily change the air blowing direction within a certain range.
そして、上記の目的を達成するために、本考案

The projecting pieces of each stay 4 and 9 are pivotally connected to the short pipe 2 by bolts 20 and nuts 21, respectively, and attached to the short pipe 2. And air outlet 1
In order to connect the gap between the flange 7 of the pipe 9 and the flange 3 of the short pipe 2, a bellows 22 is attached at both ends to the flanges 3 and 7 in an airtight manner. The bellows 22 is made of canvas or the like, processed to prevent wind from passing through, and its outer diameter is approximately equal to the outer diameter of the short tube 2.

The respective positioning plates 10 attached to are located at positions facing each other. Both positioning plates 5 and 10 have holes (not shown) drilled in each.
The positioning bolts 23, 23 are inserted through them. Then, when each positioning bolt 23 is screwed into the wing nuts 24 and 24A on both sides of the positioning plate 5, and the nut 25 is screwed into the outside of the positioning plate 10 (on the connection tube 6 side), the distance between both positioning plates 5 and 10 is reduced. It is now configurable.

Loosen the wing nuts 24 and 24A or the nut 25 screwed into the handle 15 of the connecting tube 6.
When manually moved in the horizontal direction, the outlet 19 swings over a wide range in the horizontal direction (direction of arrow A or direction of arrow B in FIG. 2) about the bolt 20 as an axis with respect to both stays 4, 4 of the short pipe 2. do. When the air outlet 19 has been rotated to the desired position, tighten the wing nuts 24 and 24A of each positioning bolt 23 from both sides of the positioning plate 5, and tighten the nuts 25 to the positioning plate 10 to direct the air outlet 19 to the desired position. to be fixed.
これにより、供給ダクト１内の空調空気は短管
２、蛇腹２２、接続筒６及び吹出側円筒１６を経
て吹出部１８の向けられた方向へ吹き出す。 As a result, the conditioned air in the supply duct 1 passes through the short pipe 2, the bellows 22, the connecting cylinder 6, and the blow-off side cylinder 16, and blows out in the direction toward which the blow-off part 18 is directed.

る。すなわち、吹出口１９に回転円筒１１を設け
たことにより、吹出口１９から出る空調空気の吹
出方向の変る範囲が拡大される。 Here, the air flowing inside the connecting tube 6 is
When the pressure reaches , the air pressure decreases because the blowout part 18 becomes conical and open on the outside, and a vortex is generated on the inner wall surface of the blowout side cylinder 16, resulting in a negative pressure in this part. Therefore, when the rotating cylinder 11 is rotated by the handle 15 and the air supply port 12 of the cylinder 11 is placed over the opening 6a on one side of the connecting cylinder 6 or the two openings 6a, 6a, the outside air is drawn into the air supply port 12. And this intake port 12 and the opening 6a
It enters the connecting cylinder 6 through the air supply port 12, reaches the negative pressure part of the blowout side cylinder 16 on the side of the air supply port 12, and increases the pressure in this part. Therefore, the blowing direction of the conditioned air coming out of the blowing part 18 is bent in the opposite direction to the air supply port 12. That is, by providing the rotating cylinder 11 at the outlet 19, the range in which the blowing direction of the conditioned air coming out of the outlet 19 changes is expanded.
なお、上記実施例において短管２と接続筒６と
を蛇腹２２により連結することとしたが、蛇腹に
限定されるものでなく、蛇腹と同様の機能を有す
