Description

本発明は、開き戸に係り、詳しくは扉体の反り防止構造を備えた開き戸に関するものである。 The present invention relates to a hinged door, and more particularly to a hinged door having a warp prevention structure of a door body.

開き戸において、扉体の戸尻側の上下2点で扉体を枢支した場合には、扉体の戸尻側の高さ方向の中間部を支持する部材がないことから、扉体が熱を受けた場合に当該扉体に反りが発生するおそれがあることが知られている(特許文献1~3)。 In a hinged door, when the door body is pivotally supported at two points above and below the door tail side of the door body, the door body heats up because there is no member that supports the middle portion of the door body in the height direction on the door tail side. It is known that the door body may be warped when the door is received (Patent Documents 1 to 3).

特許文献1~3には、このような課題に対応する手段が開示されている。特許文献1~3では、扉体の戸尻側見込面に反り防止手段を設けることでこの課題に対応している。 Patent Documents 1 to 3 disclose means for dealing with such problems. Patent Documents 1 to 3 deal with this problem by providing a warp prevention means on the door end side prospective surface of the door body.

特許文献4に記載のような開き扉付き引戸を防火仕様とする場合には、同様に、開き扉の反りも問題が生じ得る。この場合、開き扉は、引戸の扉体内に設けられるため、扉体の反り防止手段は、よりシンプルな構造かつ省スペースで設置できるものであることが望ましい。
