Description

本発明は、遮熱断熱シートに関するものである。   The present invention relates to a heat insulating heat insulating sheet.

従来より梱包材として広く利用されている気泡緩衝材は、ポリスチレンフィルムによって複数の気泡室が平面上に形成されている。   In a bubble cushioning material that has been widely used as a packing material, a plurality of bubble chambers are formed on a plane by a polystyrene film.

この気泡緩衝材は、気泡室内の空気の作用によって主に緩衝材として使用されているが、その気泡室内の空気の作用によって熱の伝達が低減されることから、断熱シートとしても利用されるようになっている（たとえば、特許文献１参照。）。   This bubble cushioning material is mainly used as a cushioning material by the action of the air in the bubble chamber, but since the heat transfer is reduced by the action of the air in the bubble chamber, it is also used as a heat insulating sheet. (For example, see Patent Document 1).

特開２０１３−２２７０４０号公報JP, 2013-227040, A

ところが、上記従来の気泡緩衝材をそのまま断熱シートとして用いた場合には、断熱材としての作用があるものの、光を透過させてしまうことから遮熱性がなく、また、ポリスチレンフィルム自体に耐火性がないといった不具合があった。   However, when the conventional air bubble cushioning material is used as it is as a heat insulating sheet, it has an effect as a heat insulating material but does not have a heat shielding property because it transmits light, and the polystyrene film itself has a fire resistance. There was a problem that it was not there.

そのため、上記従来の気泡緩衝材を断熱シートとして用いて、被災時等の簡易的なテントなどを形成することは困難であった。   Therefore, it has been difficult to form a simple tent or the like in the event of a disaster by using the conventional bubble cushioning material as a heat insulating sheet.

そこで、請求項１に係る本発明では、複数の気泡室が形成された可撓性を有する空気層の表面及び裏面に光を反射する反射面が形成された可撓性を有する反射層を設けた矩形状のシート本体の各辺に他のシート本体を接続するための拡張片を設けた遮熱断熱シートにおいて、前記シート本体の各辺に設けられた拡張片のうち、一の拡張片は、基端部がシート本体の端縁部上側にシート本体の内側へ向けて伸延させて取付けられるとともに、中途部が基端部から上側に折曲され基端部の上側面に沿ってシート本体の外側へ向けて伸延されシート本体の端縁部上側からシート本体の端縁部下側に折曲され、先端部がシート本体の端縁部下側にシート本体の内側へ向けて伸延させて着脱自在に取付けられ、その一の拡張片と対向する辺に設けられた他の拡張片は、基端部がシート本体の端縁部下側にシート本体の内側へ向けて伸延させて取付けられるとともに、中途部が基端部から下側に折曲され基端部の下側面に沿ってシート本体の外側へ向けて伸延されシート本体の端縁部下側からシート本体の端縁部上側に折曲され、先端部がシート本体の端縁部上側にシート本体の内側へ向けて伸延させて着脱自在に取付けられていることにした。
Therefore, in the present invention according to claim 1, a flexible reflective layer having reflective surfaces for reflecting light is provided on the front and back surfaces of a flexible air layer in which a plurality of bubble chambers are formed.
