Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、防火シャッターに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fireproof shutter.
一般にシャッターは第３図〜第５図に示すように帯板に
よるスラット１を繋ぎ合わせてなるもので、天井裏等の
収納ボックス２内の巻取り軸３に根本端から巻取られて
収納されるものである。Generally, the shutter is formed by connecting the slats 1 made of strips as shown in FIGS. 3 to 5, and is stored by being wound up from the root end on the winding shaft 3 in the storage box 2 such as the ceiling. It is something.
そして、先端を引くと巻取り軸３が介装したバネに抗し
て回転しながらスラット１がレール４に沿って引き出さ
れる。このようにしてシャッターを閉める。When the tip is pulled, the slat 1 is pulled out along the rail 4 while rotating against the spring provided by the winding shaft 3. The shutter is closed in this way.
また、シャッターを開けるにはスラット１を持ち上げれ
ば、バネにより付勢される巻取り軸３に巻取られる。To open the shutter, the slat 1 is lifted, and the slat 1 is wound around the winding shaft 3 urged by a spring.
ところで、現在シャッターのうち、防火機能（甲種防
火、乙種防火）を有するものは、スラット１を含めて全
体が金属製、あるいはステンレス製のものがほとんどで
ある。By the way, at present, most shutters having a fireproof function (type A fireproof, type B fireproof) are made entirely of metal or stainless steel, including the slats 1.
しかしこのような従来の防火シャッターでは、火災発生
時の加熱によりシャッター自体が強度を失うとともに、
熱膨張によりスラット１がレール４からはずれてしまう
おそれもあり、防火、防煙性能に問題を生じる。However, in such a conventional fireproof shutter, the shutter itself loses strength due to heating when a fire occurs,
There is also a risk that the slat 1 will be disengaged from the rail 4 due to thermal expansion, which causes a problem in fireproof and smokeproof performance.
さらに、シャッターが閉まっていると全面的に視界がな
くなり、火災等において避難するのに支障をきたすこと
もある。Further, when the shutter is closed, the visibility is completely lost, which may hinder evacuation due to a fire or the like.
本考案の目的は前記従来例の不都合を解消し、熱に強
く、かつ視界確保が可能な防火シャッターを提供するこ
とにある。An object of the present invention is to provide a fireproof shutter that eliminates the disadvantages of the conventional example, is resistant to heat, and can secure a visual field.
本考案は前記目的を達成するため、上下端相互に嵌合リ
ブを設けたスラットを透明なアルミナセラミックで成形
し、この嵌合リブ同士の結合で該スラットをすだれ状に
繋ぎ合わせたことを要旨とするものである。In order to achieve the above-mentioned object, the present invention forms a slat provided with fitting ribs at the upper and lower ends of a transparent alumina ceramic, and connects the slat in a comb shape by coupling the fitting ribs. It is what
本考案によれば、スラットはファインセラミックで形成
してあるので、強度を有するだけでなく、高熱にも耐え
るものとなり、熱膨張もほとんど生じない。According to the present invention, since the slats are made of fine ceramics, they have strength and can withstand high heat, and thermal expansion hardly occurs.
さらに、スラットは透明なので閉めた状態でもシャッタ
ーの反対側が見え、視界が確保できる。In addition, since the slats are transparent, the other side of the shutter can be seen even when the slats are closed, thus ensuring visibility.
以下、図面について本考案の実施例を詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第１図は本考案の防火シャッターの１実施例を示す斜視
図、第２図は同上縦断側面図である。FIG. 1 is a perspective view showing an embodiment of a fireproof shutter of the present invention, and FIG. 2 is a vertical side view of the same.
本考案のシャッターも基本的な構成は前記第３図〜第５
図に示した従来タイプと同じであり、帯板によるスラッ
ト１を繋ぎ合わせてなるもので、天井裏等の収納ボック
ス２内の巻取り軸３に根本端から巻取られて収納される
ものである。The shutter of the present invention also has the basic structure shown in FIGS.
It is the same as the conventional type shown in the figure, and is made by connecting the slats 1 by strips, and is stored by being wound up from the root end on the winding shaft 3 in the storage box 2 such as in the ceiling. is there.
スラット１の形状も第３図に示すような相互に嵌合リブ
1a,1bを有し、このリブ1a,1b同士の結合で帯状の板がす
だれ状に繋がるものであるが、本考案ではこのスラット
１をファインセラミック５で形成する。The shape of the slat 1 is also a mutually fitting rib as shown in FIG.
Although the strips 1a and 1b are provided and the strip-shaped plates are connected to each other in a comb shape by the connection between the ribs 1a and 1b, in the present invention, the slats 1 are formed of fine ceramics 5.
ファインセラミックには材質別に、酸化アルミニウム
（Al2O3）を主体とするアルミナセラミック、炭化けい
素（SiC）を主体とするもの、窒化けい素（Si3N4）を主
体とするものなど種々があるが、本考案ではアルミナセ
ラミックを使用した。There are various types of fine ceramics such as alumina ceramics mainly composed of aluminum oxide (Al 2 O 3 ), those mainly composed of silicon carbide (SiC) and those mainly composed of silicon nitride (Si 3 N 4 ). Although, there is an alumina ceramic in the present invention.
さらに、このアルミナセラミックは透明にすることがで
きるので、透明なファインセラミック５として前記スラ
ット１を透明なものとして成形した。Further, since this alumina ceramic can be made transparent, the slat 1 was formed as a transparent fine ceramic 5 so as to be transparent.
なお、収納ボックス２内では巻取り軸３の他にガイド軸
６を設けた複軸構造とすれば、スラット１の巻上げ、引
き出し時における衝撃を少なくして、セラミックの欠点
である衝撃性の弱さを補うこともできる。If the storage box 2 has a multi-axis structure in which a guide shaft 6 is provided in addition to the winding shaft 3, the shock at the time of winding and pulling out the slat 1 is reduced, and the shock resistance, which is a defect of ceramics, is weak. You can make up for it.
また、レール４は従来と同じくステンレス等の金属製で
よいが、この部分もファインセラミックとしてもよい。Further, the rail 4 may be made of metal such as stainless steel as in the conventional case, but this portion may be made of fine ceramic.
このようにして、スラット１は透明なファインセラミッ
ク５で構成されており、2,000℃以上の融点を持ち、耐
熱性、耐蝕性、及び強度がガラスよりも優れたものとな
る。Thus, the slats 1 are composed of the transparent fine ceramics 5, have a melting point of 2,000 ° C. or higher, and are superior in heat resistance, corrosion resistance, and strength to glass.
また、熱膨張率は金属の1/10以下であり、火災発生時の
高温（1,000℃）程度では強度に変化を生じない。In addition, the coefficient of thermal expansion is 1/10 or less of that of metal, and its strength does not change at high temperatures (1,000 ° C) when a fire occurs.
以上述べたように本考案の防火シャッターは、従来のス
テンレス製のシャッターに比べて熱に強く、火災発生時
の加熱によりシャッター自体が強度を失うようなことが
なく、また、熱膨張も生じにくいので、スラットが膨張
してレールからはずれてしまうおそれもなく、防火、防
煙性能に優れるものである。As described above, the fireproof shutter of the present invention is more resistant to heat than conventional stainless steel shutters, the shutter itself does not lose its strength due to heating when a fire occurs, and thermal expansion does not easily occur. Therefore, there is no fear that the slat will expand and come off the rail, and it has excellent fire and smoke prevention performance.
さらに、シャッターが閉まっている時でも、スラットを
通してシャッターの反対側が見え、視界確保ができるの
で、避難するのに支障をきたすおそれがないものであ
る。Furthermore, even when the shutter is closed, the other side of the shutter can be seen through the slats and the visibility can be secured, so there is no danger of hindering evacuation.
