【発明の属する技術分野】
本発明は建物の屋上の機械室等に使用される排気ガラリに関する。
【０００２】
【従来の技術】
従来の排気ガラリは建物の開口部の周縁部に取付けられる枠状のフレ−ムと、この枠状のフレ−ムの両側部のフレ−ム部材に両端部が固定された、所定間隔でほぼ４５度傾斜する多数個の固定羽根とで構成されている。
【０００３】
【発明が解決しようとする課題】
従来の排気ガラリは枠状のフレ−ムに所定間隔で多数個の固定羽根を取付けているため、室内の排気や排煙を多数個の固定羽根間より外部へ排出したり、外部より空気が侵入して換気を行なうことができるが、常時多数個の固定羽根間は開放状態となっているため、暴風雨の場合には多数個の固定羽根間より暴風雨が室内へ浸入し、室内を汚してしまう等の欠点があった。
【０００４】
本発明は以上のような従来の欠点に鑑み、通常時には多数個の開閉羽根が開放状態になっており、排気、排煙、換気を行なうことができるとともに、暴風雨の場合には多数個の開閉羽根間に隙間が生じないように自動的に閉じて、内部への暴風雨の浸入を阻止することができる排気ガラリを提供することを目的としている。
【０００５】
本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、本発明は建物の開口部の周縁部に取付けられる枠状のフレ−ムと、この枠状のフレ−ムの対向するフレ−ム部材に所定間隔で両端部が枢支され、所定量以上の風圧が作用すると該風圧によって回動して、該フレ−ムの開口部を閉じる多数個の開閉羽根と、この多数個の開閉羽根に取付けられた、常時は開放状態を保ち、所定量以上の風圧が作用すると該風圧によってフレ−ムの開口部を閉じるように作用させることができる開閉羽根支持手段とで排気ガラリを構成している。
【０００７】
【発明の実施の形態】
以下、図面に示す実施の形態により、本発明を詳細に説明する。

【０００９】
前記多数個の開閉羽根６は先端両側部が前記枠状のフレ−ム５の前面板５ｃ、５ｃに当接する、ほぼへ字状に形成された開閉羽根本体８と、この開閉羽根本体の両側部より外方へ突出するように形成された、前記フレ−ム部材５ａ、５ａの側面板５ｄ、５ｄに形成された軸９、９に回動可能に支持される筒状の軸受１０、１０とで構成されている。
【００１０】
前記開閉羽根支持手段７は前記開閉羽根６の後端部に、それぞれ一体あるいは固定的に取付けられた重り１１で構成されている。
【００１１】
上記構成の排気ガラリ１は、常時は開閉羽根支持手段７としての開閉羽根６の重り１１によって、開閉羽根６の先端部がフレ−ム部材５ａ、５ａの前面板５ｃ、５ｃに当接された、開閉羽根６、６間が開放された状態となっている。
このため、排気、排煙や換気を行なうことができる。
強風や暴風雨時には多数個の開閉羽根６に風が当り、該風圧が開閉羽根支持手段７としての開閉羽根６の重り１１の付勢力よりも大きくなると、開閉羽根６を閉じる方向に自動的に回動させて、枠状のフレ−ム５の開口部５ｂを閉じ、室内への風、雨の浸入を自動的に阻止する。

【００１５】
図１３ないし図１５に示す本発明の第４の実施の形態において、前記本発明の第３の実施の形態と主に異なる点は、多数個の開閉羽根６Ａを強制的に閉状態を保つことができる多数個の開閉羽根６Ａを同時に閉状態にするように取付けられた紐やワイヤ−１８と、この紐やワイヤ−１８の下端部を係止させる枠状のフレ−ム５Ａの下部フレ−ム部材１３に取付けられた着脱可能な係止具１９とからなる閉状態保持機構２０を備えた開閉羽根支持手段７Ｂを用いた点で、このような開閉羽根支持手段７Ｂを用いて構成した排気ガラリ１Ｃにしても、前記本発明の第３の実施の形態と同様な作用効果が得られる。

[Prior art]
A conventional exhaust gallery has a frame-like frame attached to the periphery of an opening of a building and frame members at both ends fixed to frame members on both sides of the frame-like frame. It is composed of a number of fixed blades inclined at 45 degrees.
[0003]
[Problems to be solved by the invention]
In the conventional exhaust gallery, a large number of fixed blades are attached to the frame-shaped frame at predetermined intervals, so that indoor exhaust and smoke are discharged to the outside from between the many fixed blades, and air is discharged from the outside. It can invade and ventilate, but since many fixed blades are always open, in case of storms, storms infiltrate into the room from between many fixed blades and contaminate the room. There were drawbacks such as getting lost.
[0004]
In view of the above disadvantages of the present invention, the present invention normally has a large number of opening and closing blades in an open state, and can perform exhaust, smoke exhaust, ventilation, and in the case of a storm, a large number of opening and closing. It is an object of the present invention to provide an exhaust gutter which can be automatically closed so that no gap is generated between the blades and can prevent intrusion of storm into the inside.

A frame-shaped frame 5 formed by using an angle material attached to a peripheral portion of the portion 4 and opposite frame members 5a and 5a of the frame-shaped frame 5 are pivotally fixed at both ends at predetermined intervals. It is supported, and when a wind pressure of a predetermined amount or more acts thereon, it is rotated by the wind pressure to close the opening 5b of the frame-shaped frame 5, and a number of opening / closing blades 6 are attached to the plurality of opening / closing blades 6. Open / close blade supporting means 7 which can be kept open at all times and act to close the opening 5b of the frame 5 when the wind pressure exceeds a predetermined amount. ing.
[0009]
The plurality of opening / closing blades 6 are formed in a substantially U-shaped opening / closing blade main body 8, both ends of which contact the front plates 5 c, 5 c of the frame-shaped frame 5, and both sides of the opening / closing blade main body. Cylindrical bearings 10, 10 rotatably supported by shafts 9, 9 formed on the side plates 5d, 5d of the frame members 5a, 5a formed so as to protrude outward from the portions. It is composed of
[0010]
The opening / closing blade supporting means 7 is constituted by a weight 11 integrally or fixedly attached to the rear end of the opening / closing blade 6.
[0011]
In the exhaust gallery 1 having the above structure, the tip of the opening / closing blade 6 is always in contact with the front plates 5c, 5c of the frame members 5a, 5a by the weight 11 of the opening / closing blade 6 as the opening / closing blade supporting means 7. The opening and closing blades 6 are open.
Therefore, exhaust, smoke exhaust, and ventilation can be performed.
When the wind hits a large number of the opening / closing blades 6 in a strong wind or a storm, when the wind pressure becomes larger than the urging force of the weight 11 of the opening / closing blade 6 as the opening / closing blade supporting means 7, the opening / closing blade 6 is automatically turned in the closing direction. By moving the frame, the opening 5b of the frame 5 is closed to automatically prevent the wind and rain from entering the room.
