る換気装置に関する。[Detailed Description of the Invention] Industrial Application Field This invention relates to a ventilation device that is fitted into a ceiling opening of a unit room, for example, and connected to a ventilation duct that exhausts the air to the outside.
従来の技術
従来この種の換気装置は第3図のような構造に
なつていた。Prior Art Conventionally, this type of ventilation system had a structure as shown in Figure 3.
すなわちユニツトルームの天井1の開口部に換

た。 The closing structure of conventional ventilation equipment is the outer cylinder 3 of the ventilation opening.
A plurality of slide legs 6 are fitted around the periphery of the opening/closing cover 5 that slides on the inner surface, and at the position where the knob 7 is pressed,
The peripheral edge 8 of the opening/closing cover 5, the inner surface of the vent outer tube 3, the locking tube 9, and the opening/closing cover 5 were in close contact to close the exhaust passage. Further, when opening the exhaust passage, the opening/closing cover was moved downward by a distance A as shown by the solid line in FIG. 3 to secure the opening area.

広くとれるようにするものである。Problems to be Solved by the Invention However, with such a structure, if the ventilation port outer case 3 is deformed during the work of connecting the ventilation duct 4 to the ventilation port outer case 3, the fitting with the sliding leg 6 of the opening/closing cover 5 may occur. The opening/closing cover 5 becomes hard and cannot be opened and closed smoothly, and when opening the exhaust passage, the opening/closing cover 5 descends below the ventilation port body 2, resulting in a problem that the effective indoor height of the unit room becomes low. Therefore, the present invention is designed to prevent the ventilation port main body 2 from being affected by the deformation of the ventilation port outer cylinder 3 when connecting the exhaust duct.
The exhaust passage can be opened and closed smoothly, and the exhaust passage can be widened by a slight movement of the opening/closing cover 5.
問題点を解決するための手段
そして上記問題点を解決する本考案の技術的な
手段は、換気口外筒内方にガイド筒を設け、上記
ガイド筒内面に開閉カバーを移動自在に取付ける
とともに、筒状のガイド筒は、開閉体側に向かつ
て外方へ広がる円錐状に形成したものである。Means for Solving the Problems The technical means of the present invention for solving the above problems is to provide a guide cylinder inside the outer cylinder of the ventilation port, to attach an opening/closing cover movably to the inner surface of the guide cylinder, and to The shaped guide tube is formed into a conical shape that widens outward toward the opening/closing body.
作 用 この技術的手段による作用は次のようになる。Effect The effect of this technical means is as follows.
すなわち、換気口本体の外筒内面に設けたガイ
ド筒に開閉カバーのスライド脚を嵌合させ、この
間のスライド動作により、換気口本体の排気通路
を開閉するが、前記ガイド筒は、開閉体側に向か
い、外方へ広がる円錐状に形成する。 That is, the sliding legs of the opening/closing cover are fitted into the guide tube provided on the inner surface of the outer cylinder of the ventilation port body, and the sliding action during this period opens and closes the exhaust passage of the ventilation port body. Form into a conical shape that spreads outward.
この結果、換気ダクトの接続連結時に、外筒が
変形しても、ガイド筒の内面は変形することがな

状になつているので、開閉カバーのわずかな移動
で排気通路を広くとれ、開閉カバーは換気口本体
より下方にさがることなく、ユニツトルーム内の
室内高さが低くなることもない。 As a result, even if the outer cylinder is deformed when the ventilation duct is connected, the inner surface of the guide cylinder will not be deformed, and the state of engagement with the sliding legs of the opening/closing cover will not change, allowing smooth opening and closing operations. As the guide tube moves toward the opening and closing body, it becomes a conical shape that expands outward, so the exhaust passage can be widened with a slight movement of the opening and closing cover, and the opening and closing cover does not go down below the vent body, allowing the unit to open. The indoor height of the room does not become low.

設けているので落下することもない。 Next, the operation of the configuration of this embodiment will be explained. The sliding leg 16 of the opening/closing cover 13 is fitted into the guide groove 17 of the guide cylinder 12, and when the operating knob 15 is pulled downward from the state shown by the imaginary line in FIG. As shown, the necessary exhaust passage A is secured between the ventilation port main body 10, but since the guide tube faces the opening/closing body side and has a conical shape that spreads outward, the opening/closing cover 13
A wide opening is formed with a slight movement of the Since the slide leg 16 slides within the guide groove 17,
It operates smoothly without rattling, and since the tip of the slide leg 16 is provided with an outwardly protruding locking portion 18, it will not fall.
