エザーカバーに関する。[Detailed description of the invention] <Industrial field of application> This invention is a fire damper that is installed on the outer wall of a high-rise building such as an apartment complex and connected to a range hood, etc. installed indoors by an exhaust duct. Regarding the attached weather cover.

する様にしていた。<Conventional technology and its problems> Conventionally, in this type of weather cover with a fire damper, the fire damper was stored and held in the cover body by rotating around one side of the opening edge (inner surface of the front edge) of the bottom exhaust outlet of the cover body. A cover body is provided with a mounting piece for attaching one end of a temperature fuse to one edge of the fire damper, which is pivotably mounted on the fire damper, and the other edge facing the other edge thereof, and the other edge is close to the other edge when the fire damper is in the retracted and upright state. A mounting piece for attaching the other end of the temperature fuse is provided on the upper inner surface of the cover, and by installing the temperature fuse between this mounting piece and the above-mentioned mounting piece, the exhaust outlet of the cover body can be automatically closed in the event of a fire, etc. It was designed to store and hold the blocking fire damper.

火対策上好ましい格納構造ではなかつた。 However, in the conventional fire prevention damper storage structure, the damper itself has attached parts such as mounting pieces for attaching the temperature fuse, so when a fire occurs, the temperature fuse is cut off due to high heat and the fire prevention damper is kept in the retracted state. When the fire damper is released and the fire damper is tilted under its own weight in a direction that blocks the exhaust outlet, the attached member and the fuse piece that remains after being cut rest on the bird-proofing net stretched over the exhaust outlet. However, the fire damper did not have a suitable storage structure for fire prevention, as it stopped mid-tilt before completely blocking the exhaust outlet.

る。<Problem to be solved by the invention> The technical problem to be solved by the invention is to store and maintain the damper inside the cover body with the temperature fuse without providing any attached parts in order to freely attach the temperature fuse to the fire damper. By providing a weather cover with a fireproof damper, the fireproof damper completely tilts over the exhaust outlet and secures the outlet when a temperature fuse is blown due to high heat during a fire or the like. It is to block the situation.

たことを特徴とする。<Means for Achieving the Technical Problem> The technical means taken by the present invention to achieve the above-mentioned problem is to store and hold a fire damper that is rotatably pivoted on one side of the opening edge of the exhaust outlet. One end of the presser rod, which has an abutment part in the middle for locking the presser in the direction, is pivotally attached to the upper inner surface of the cover main body, and the presser rod is arranged in a hanging manner, and the pivot point at one end of this presser rod is used as a fulcrum. A temperature fuse is strung across the entire presser rod from the other end of the presser rod to the upper inner surface of the cover body via a spring material attached to the damper retracting direction, and the presser rod is pressed and biased in the retracting direction. The fire damper is characterized in that the tip side is brought into contact with the inner surface of the cover body.

る。<Function> According to the above-mentioned technical means of the present invention, when a temperature fuse is blown due to high heat during a fire or the like, the midway abutting portion is brought into contact with the fire damper and the damper is activated. The presser rod, which is biased by a spring member in the retracting direction of the damper that locks the presser foot, is in a free state with its upper end pivoted as a fulcrum. As a result, the fire prevention damper is released from its stored state and tilts under its own weight in the direction of closing the exhaust outlet, thereby closing the exhaust outlet.
又、温度ヒユーズが高熱によつて切れる以前は
押え杆が防火ダンパーを格納方向に押圧付勢して

保持する。<Example> An example of the present invention will be described based on the drawings.
The cover body 1 includes a curved plate 1a extending from the top surface to the front surface, and a back plate 1 having an exhaust inlet 3 connected to a range hood etc. through an exhaust duct 2.
A bird-preventing net 5 is stretched over the entire surface of the exhaust outlet 4 which is opened on the lower surface thereof, and on one side of the opening edge (inner surface of the front edge).
One edge of a fireproof damper 6 that closes the outlet 5 is rotatably mounted on a pivot 7, and the fireproof damper 6 is stored and held within the cover body 1 by a storage and holding device A.

成してなる。 The storage/holding device A includes a presser rod A 1 equipped with a contact portion 8 in the middle that presses and locks the fire damper 6 in the storage direction, and a spring member that biases the entire presser rod A 1 in the damper 6 storage direction. It consists of a temperature fuse A2 and a temperature fuse A3 .

図示した様に当接部８を防火ダンパー６の格納方
向（傾斜起立方向）に向ける。 The presser rod a 1 is made by bending a desired elongated metal rod material such as wire into a roughly V-shape (bifurcated shape) from the front, and bending both rod materials 100 from the middle part into a roughly V-shape from the side. The open end (one end) of both rod members 100 is rotated to a hanging fixture 9 fixedly attached to the upper inner surface of the cover main body 1. The presser foot a1 is freely pivoted and placed in a hanging shape. At this time, as shown in the figure, the contact portion 8 is oriented in the retracting direction (tilting direction) of the fire damper 6.
バネ材a2は、上端枢着部１０を支点に宙ぶらり

杆a1と同様に垂下状に配備する。 The spring material A2 is moved from the suspension fitting 9 in such a way that the entire presser rod A1 , which is suspended in the air with the upper end pivoting part 10 as a fulcrum, is attached in the direction in which the damper 6 is stored, with the pivoting part 10 as the fulcrum. It is strung across the other end (lower end) of the presser rod A 1 together with the temperature fuse A 3 , and one end of it is connected to the upper edge of the fire damper 6 which is stored and held in an inclined upright position and the upper end pivot of the presser rod A 1 . It is latched and fixed to the hanging metal fitting 9 between the attachment part 10 and arranged in a hanging shape like the presser rod A1 .

防火ダンパー６に当接させるものである（第１図
乃至第３図）。 Then , one end of temperature fuse A3 is hooked to the other end (lower end) of spring material A2 , and the other end (lower end) of temperature fuse A3 is held down via hook rod A4 to the lower end of rod A1 . The presser rod A1 is urged in the damper 6 retracting direction, and the contact portion 8 of the presser rod A1 is brought into contact with the fire damper 6 (Figs. 1 to 3). .

（第４図及び第５図）。 When the temperature fuse A3 is blown due to high heat in the event of a fire, etc., the presser rod A1 becomes free and dangling around its upper end pivot point 10, and the fire damper 6 is retracted. The holding state is released and the device falls down, thereby blocking the exhaust outlet 4 (FIGS. 4 and 5).

て押え係止する形状であればよい。 Although the above embodiment has been described in detail as a form in which the presser rod a 1 is bent in a substantially dogleg shape on its side to provide the contact portion 8 in the middle thereof, the present invention is limited to this form. The presser rod a1 , which has the upper end pivot portion 10 as its fulcrum, is not attached to the damper 6 by the spring material a2.
Any shape is acceptable as long as the midway portion thereof comes into contact with and presses the fire damper 6 stored and held in the inclined upright state when it is biased in the retracting direction.

る。<Effects of the invention> Since the weather cover with a fire damper of the present invention is constructed as described above, the fire damper, which is released from the retracted state when the temperature fuse is blown, completely closes the exhaust outlet under its own weight. The outlet is tilted down onto a bird-prevention net stretched over the ground to reliably close the outlet.

することが出来る。 In addition, since the fire damper is pressed against the inner surface of the cover body via a presser rod, the fire damper will not rattle due to the exhaust (air blow) from the range hood side or the inflow of outdoor wind. Moreover, since the fire damper does not rattle within the cover body during transportation of this product, the temperature fuse, which is stretched across the spring material attached to the cover body and the presser rod, is prevented from breaking before use. I can do it.
