蝶番１１ａ，１１ｂ，１１ｃは、図３に示すように、戸２の上部位置と、戸２の上下方向中間部上寄りの位置と、戸２の下部位置の３箇所に設けてある。本建具は、後述するように、戸２に水圧がかかったときに、戸２の下部が室内側に変位して下枠１３と縦枠１４のタイト材３ａ，３ｂに圧着するように、戸２の下端より下側の蝶番１１ｃ（の中心）までの寸法Ｌ１が戸２の上端より上側の蝶番１１ａ（の中心）までの寸法Ｌ２より長くしてある。具体的には、戸２の下端より下側の蝶番１１ｃまでの寸法Ｌ１を５００ｍｍ、戸２の上端より上側の蝶番１１ａまでの寸法Ｌ２を２４５ｍｍとしてある。 As shown in FIG. 3, the hinges 11a, 11b, and 11c are provided at three positions: an upper position of the door 2, a position above the middle portion in the vertical direction of the door 2, and a lower position of the door 2. As will be described later, this fitting is a door so that when water pressure is applied to the door 2, the lower part of the door 2 is displaced toward the room and is crimped to the tight materials 3a and 3b of the lower frame 13 and the vertical frame 14. The dimension L1 from the lower end of 2 to the hinge 11c (center) is longer than the dimension L2 to the hinge 11a (center) above the upper end of the door 2. Specifically, the dimension L1 from the lower end of the door 2 to the hinge 11c below is 500 mm, and the dimension L2 from the upper end of the door 2 to the hinge 11a above is 245 mm.

本建具は、以下に説明するように、洪水等で室外側の水位が高まったときに、外部水圧を利用したドアタイト性向上による耐水機構を備えている。
図８，９は、室外側が半分程度の高さまで水３８に浸かった状態を示している。このとき戸２は、戸２の下端より下側の蝶番１１ｃまでの寸法Ｌ１が戸２の上端より上側の蝶番１１ａまでの寸法Ｌ２より長くしてあることで、図８（ｂ）に示すように、戸２が外部水圧により下部が室内側に撓み変形し、これに伴い下枠１３のタイト材３ｂ及び縦枠１４のタイト材３ａにより強く押し付けられる。このときに下枠のタイト材３ｂは、図８（ｃ）に示すように、戸当接部８が戸２のコーナー部３７に沿う形で変形して戸２のコーナー部３７をくわえ込む。また縦枠１４のタイト材３ａは、図９（ａ），（ｂ）に示すように、戸当接部８が戸２のコーナー部３７に沿って変形し、変形した戸当接部８が外周側連結壁２７と内周側連結壁２８の間に入り込む形で、戸２のコーナー部３７をくわえ込む。戸２は、下に行くほど水圧による室内側への変位量が大きく、その分タイト材３ａに強く圧着する。外周側連結壁２７と内周側連結壁２８を戸当接部８よりも硬い材質で形成したことで、水圧を受けても外周側連結壁２７と内周側連結壁２８が変形せずに元の形態を維持し、戸当接部８が水圧で内周側に押し流されて戸２との間に隙間があくのを防止できる。 As explained below, this fitting is equipped with a water resistance mechanism that improves door tightness by using external water pressure when the water level outside the room rises due to floods or the like.
FIGS. 8 and 9 show a state in which the outdoor side is immersed in water 38 to a height of about half. At this time, the door 2 has a dimension L1 up to the hinge 11c below the lower end of the door 2 longer than the dimension L2 up to the hinge 11a above the upper end of the door 2, as shown in FIG. 8 (b). In addition, the lower part of the door 2 is bent and deformed toward the room due to the external water pressure, and accordingly, the door 2 is strongly pressed by the tight material 3b of the lower frame 13 and the tight material 3a of the vertical frame 14. At this time, as shown in FIG. 8C, the tight material 3b of the lower frame is deformed so that the door contact portion 8 is formed along the corner portion 37 of the door 2 and holds the corner portion 37 of the door 2. Further, in the tight material 3a of the vertical frame 14, as shown in FIGS. 9A and 9B, the door contact portion 8 is deformed along the corner portion 37 of the door 2, and the deformed door contact portion 8 is formed. The corner portion 37 of the door 2 is gripped so as to enter between the outer peripheral side connecting wall 27 and the inner peripheral side connecting wall 28. The lower the door 2, the larger the amount of displacement toward the room due to water pressure, and the stronger the pressure is applied to the tight material 3a. By forming the outer peripheral side connecting wall 27 and the inner peripheral side connecting wall 28 with a material harder than the door contact portion 8, the outer peripheral side connecting wall 27 and the inner peripheral side connecting wall 28 are not deformed even when subjected to water pressure. The original shape can be maintained, and the door contact portion 8 can be prevented from being swept toward the inner peripheral side by water pressure and a gap is formed between the door contact portion 8 and the door 2.

図１０，１１は、比較例として、戸２の下端より下側の蝶番１１ｃまでの寸法Ｌ１と戸２の上端より上側の蝶番１１ａまでの寸法Ｌ２を同じにした場合（いずれも２４５ｍｍ）をした場合を示している。比較例では、同じように半分程度まで水３８に浸かった場合でも、戸２の下端部がわずかに室内側に変位するのみで、戸２の下端より２４５ｍｍ上に上がったＥ−Ｅ断面（図８のＣ−Ｃ断面と同じ高さ位置）では、図１１（ａ）に示すように、蝶番１１ｃで拘束されているために戸２は室内側に変位せず、したがってタイト材３ａのタイトが不十分となり、タイト材３ａと戸２の間から水が浸入するおそれがある。 As a comparative example, FIGS. 10 and 11 show the case where the dimension L1 up to the hinge 11c below the lower end of the door 2 and the dimension L2 up to the hinge 11a above the upper end of the door 2 are the same (both are 245 mm). Shows the case. In the comparative example, even when the door 2 is immersed in water 38 to about half, the lower end of the door 2 is only slightly displaced toward the room, and the EE cross section rises 245 mm above the lower end of the door 2 (FIG. (At the same height position as the CC cross section of 8), as shown in FIG. 11 (a), the door 2 is not displaced to the indoor side because it is restrained by the hinge 11c, and therefore the tight material 3a is tight. It becomes insufficient, and water may infiltrate between the tight material 3a and the door 2.

このように本建具は、戸２に水圧がかかったときに戸２の下部が室内側に変位して下枠１３と縦枠１４のタイト材３ａ，３ｂに圧着し、しかもタイト材３ａ，３ｂは戸２のコーナー部３７をくわえ込むため、戸２とタイト材３ａ，３ｂの間から水が室内に浸入するのを防止することができる。
