Abstract

To provide a fixture capable of preventing an inner window from being deformed or damaged or like.SOLUTION: A fixture is provided with an outer window 1 and an inner window 2, wherein the inner window 2 comprises soft fins 4a, 4b filling gaps between frames 3a, 3b and sashes 6, 7 to release pressure in a middle layer 5 by deformation of the soft fins 4a, 4b created by pressure difference between the middle layer 5 positioned in a middle of the outer window and the inner window and an inside of a room.SELECTED DRAWING: Figure 1

Description

本発明は、外窓と内窓を備える建具に関する。 The present invention relates to a fitting including an outer window and an inner window.

従来より、断熱性や遮音性を向上するために、既存の窓（外窓）の室内側に内窓を設置することがある。このような二重窓においては、外窓に強い風圧（正圧、負圧）を受けると、外窓・内窓間の中間層が外窓に押されて圧縮されたり引っ張られて膨張したりして、中間層の圧力が変化し、これが原因で内窓が変形したり破損したりするおそれがある。これを防ぐために、どのサッシメーカーも、強風時や長期不在時には、内窓を少し開けるように注意喚起を行っており（非特許文献１参照）、せっかくの内窓の効果が損なわれている。また、中高層の建物に内窓を設置した場合には、戸建て住宅の場合よりも風圧による使用環境が悪くなるので、内窓が変形したり破損したりするリスクが高まる。 Conventionally, an inner window may be installed on the indoor side of an existing window (outer window) in order to improve heat insulation and sound insulation. In such double glazing, when strong wind pressure (positive pressure, negative pressure) is applied to the outer window, the intermediate layer between the outer window and the inner window is pushed by the outer window and compressed or expanded by being pulled. Then, the pressure of the intermediate layer changes, which may deform or damage the inner window. In order to prevent this, any sash maker warns that the inner window should be opened a little during strong winds or when there is a long absence (see Non-Patent Document 1), and the effect of the inner window is impaired. Further, when the inner window is installed in a middle-high-rise building, the use environment due to wind pressure becomes worse than in the case of a detached house, and thus the risk of the inner window being deformed or damaged increases.

Has a soft fin that abuts the outer rail, and the inner shoji has a soft fin that abuts the inner rail only on the inner side of the inner rail of the frame. Due to the pressure difference, the outer shoji moves to the outside of the room and the soft fin moves away from the outer rail, or the inner shoji moves to the inside of the room and the soft fin moves away from the inner rail, releasing the pressure in the middle layer. And

請求項１記載の発明による建具は、内窓に枠と障子間の隙間を塞ぐ軟質ヒレを有し、外窓・内窓間の中間層と室内との圧力差により、軟質ヒレが変形して中間層の圧力を逃がすので、強風時に内窓を閉め切ったままでも、内窓が変形したり破損したりすることを防止できる。 The fitting according to the invention of claim 1 has a soft fin that closes the gap between the frame and the shoji in the inner window, and the soft fin deforms due to the pressure difference between the intermediate layer between the outer window and the inner window and the room. Since the pressure in the intermediate layer is released, it is possible to prevent the inner window from being deformed or damaged even when the inner window is closed in a strong wind.

請求項２記載の発明による建具は、外障子は、枠の外レールの室外側のみに外レールに当接する軟質ヒレを有し、内障子は、枠の内レールの室内側のみに内レールに当接する軟質ヒレを有し、外窓・内窓間の中間層と室内との圧力差により、外障子が室外側に移動して軟質ヒレが外レールから離れるか、内障子が室内側に移動して軟質ヒレが内レールから離れることで、中間層の圧力を逃がすので、強風時に内窓を閉め切ったままでも、内窓が変形したり破損したりすることを防止できる。 In the joinery according to the invention of claim 2, the outer shoji has a soft fin that contacts the outer rail only on the outer side of the outer rail of the frame, and the inner shoji has the inner rail only on the inner side of the inner rail of the frame. It has a soft fin that abuts, and due to the pressure difference between the middle layer between the outer and inner windows and the room, the outer shoji moves to the outside and the soft fin separates from the outer rail, or the inner shoji moves to the inside. Since the soft fin is released from the inner rail, the pressure in the intermediate layer is released, so that it is possible to prevent the inner window from being deformed or damaged even when the inner window is completely closed in strong wind.

以下、本発明の実施の形態を図面に基づいて説明する。図１，２は、本発明の建具の第１実施形態を示している。本建具は、室外側に既存の外窓１が取付けられている窓開口部の室内側に内窓２を取付けて二重窓にしたものである。 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of a fitting of the present invention. This fitting is a double window in which the inner window 2 is attached to the inside of the window opening where the existing outer window 1 is attached to the outside.

外窓１は、上枠１４と下枠１５と左右の縦枠１６，１６を枠組みしてなる枠と、枠内に引違い状に開閉自在に納めた外障子１７及び内障子１８を備える。枠１４，１５，１６と障子１７，１８の框は、アルミ製である。 The outer window 1 includes an upper frame 14, a lower frame 15, and left and right vertical frames 16, 16 as a frame, and an outer shoji 17 and an inner shoji 18 which are accommodated in the frame so as to be opened and closed in a pulling manner. Frames of the frames 14, 15 and 16 and the shoji 17 and 18 are made of aluminum.

内窓２は、上枠８と下枠１９と左右の縦枠３ａ，３ｂを、枠組みしない状態で額縁２０の内周面にそれぞれ取付けて形成した枠と、枠内に引違い状に開閉自在に納めた外障子６及び内障子７を備える。外障子６と内障子７は、上框２１と下框２２と戸先框２３と召合せ框と２４を框組みし、その内側にガラス２５を嵌め込んで構成してある。枠３ａ，３ｂ，８，１９と障子６，７の框２１，２２，２３，２４は、樹脂製である。 The inner window 2 is a frame formed by attaching the upper frame 8, the lower frame 19, and the left and right vertical frames 3a and 3b to the inner peripheral surface of the frame 20 without the frame, and can be opened and closed in a sliding manner in the frame. The external shoji 6 and the internal shoji 7 stored in The outer shoji 6 and the inner shoji 7 are constructed by assembling an upper frame 21, a lower frame 22, a door end frame 23, a summing frame and 24, and fitting a glass 25 inside thereof. The frames 3a, 3b, 8, 19 and the frames 21, 22, 23, 24 of the shoji 6, 7 are made of resin.

内窓２は、図１に示すように、左右の縦枠３ａ，３ｂの内周側面から外障子６の戸先６ａと内障子７の戸先７ａに向けてのびる軟質ヒレ４ａ，４ｂを有しており、軟質ヒレ４ａ，４ｂにより縦枠３ａ，３ｂと障子６，７の戸先６ａ，７ａとの間の隙間を塞いでいる。軟質ヒレ４ａ，４ｂは、左右の縦枠３ａ，３ｂに室内外方向に間隔をおいて２つずつ設けてある。 As shown in FIG. 1, the inner window 2 has soft fins 4a, 4b extending from the inner peripheral side surfaces of the left and right vertical frames 3a, 3b toward the door tip 6a of the outer shoji 6 and the door tip 7a of the inner shoji 7. Therefore, the soft fins 4a, 4b close the gap between the vertical frames 3a, 3b and the door ends 6a, 7a of the shoji 6,7. Two soft fins 4a, 4b are provided on the left and right vertical frames 3a, 3b at intervals in the indoor/outdoor direction.

外窓１に正圧がかかると、外窓・内窓間の中間層５が外窓１に押されて圧縮されるため、図３（ａ）に示すように、内窓２にも正圧がかかり（図中の矢印２６参照）、中間層５の気圧が室内側よりも高くなる。すると、左右の縦枠３ａ，３ｂに設けた軟質ヒレ４ａ，４ｂが室内側に向けて曲がるように変形し、軟質ヒレ４ａ，４ｂの先端が障子６，７の戸先６ａ，７ａから離れ、軟質ヒレ４ａ，４ｂの先端と障子６，７の戸先６ａ，７ａとの間の隙間を通じて中間層側から室内側に空気が流れる（図中の矢印２７参照）。これにより、中間層５の圧力が逃げ、中間層５が室内と等圧になる。
一方、外窓１に負圧がかかると、外窓・内窓の中間層５が外窓１に引っ張られて膨張するため、図３（ｂ）に示すように、内窓２にも負圧がかかり（図中の矢印２８参照）、中間層５の気圧が室内側より低くなる。すると、左右の縦枠３ａ，３ｂに設けた軟質ヒレ４ａ，４ｂが室外側に向けて曲がるように変形し、軟質ヒレ４ａ，４ｂの先端が障子６，７の戸先６ａ，７ａから離れ、軟質ヒレ４ａ，４ｂの先端と障子６，７の戸先６ａ，７ａとの間の隙間を通じて室内側から中間層側に空気が流れる（図中の矢印２９参照）。これにより、中間層５の圧力が逃げ、中間層５が室内と等圧になる。 When a positive pressure is applied to the outer window 1, the intermediate layer 5 between the outer window and the inner window is pressed by the outer window 1 and compressed, so that a positive pressure is also applied to the inner window 2 as shown in FIG. Is applied (see arrow 26 in the figure), and the atmospheric pressure of the intermediate layer 5 becomes higher than that on the indoor side. Then, the soft fins 4a, 4b provided on the left and right vertical frames 3a, 3b are deformed so as to bend toward the indoor side, and the tips of the soft fins 4a, 4b are separated from the door ends 6a, 7a of the shoji 6,7. Air flows from the middle layer side to the room side through the gap between the tips of the soft fins 4a, 4b and the door ends 6a, 7a of the shoji 6, 7 (see arrow 27 in the figure). As a result, the pressure of the intermediate layer 5 escapes, and the intermediate layer 5 becomes an equal pressure in the room.
On the other hand, when a negative pressure is applied to the outer window 1, the intermediate layer 5 between the outer window and the inner window is pulled by the outer window 1 and expands. Therefore, as shown in FIG. Is applied (see arrow 28 in the figure), and the atmospheric pressure of the intermediate layer 5 becomes lower than the indoor side. Then, the soft fins 4a and 4b provided on the left and right vertical frames 3a and 3b are deformed so as to bend toward the outdoor side, and the tips of the soft fins 4a and 4b are separated from the door ends 6a and 7a of the shoji 6,7. Air flows from the indoor side to the intermediate layer side through the gap between the tips of the soft fins 4a, 4b and the door ends 6a, 7a of the shoji 6, 7 (see arrow 29 in the figure). As a result, the pressure of the intermediate layer 5 escapes, and the intermediate layer 5 becomes an equal pressure in the room.

以上に述べたように本建具は、内窓２に枠（縦枠）３ａ，３ｂと障子６，７間の隙間を塞ぐ軟質ヒレ４ａ，４ｂを有し、外窓・内窓間の中間層５と室内との圧力差により、軟質ヒレ４ａ，４ｂが変形して中間層５の圧力を逃がすので、強風時に内窓２を閉め切ったままでも、内窓２が変形したり破損したりすることを防止できる。
本建具は、縦枠３ａ，３ｂに軟質ヒレ４ａ，４ｂを追加するだけでよいため、容易に実施できる。 As described above, the present fitting has the soft fins 4a and 4b for closing the gap between the frames (vertical frames) 3a and 3b and the shoji 6 and 7 in the inner window 2, and the middle layer between the outer window and the inner window. Since the soft fins 4a and 4b are deformed by the pressure difference between the inner window 2 and the room to release the pressure of the intermediate layer 5, the inner window 2 may be deformed or damaged even when the inner window 2 is closed in a strong wind. Can be prevented.
This fitting can be easily implemented because it only needs to add the soft fins 4a and 4b to the vertical frames 3a and 3b.

図４〜６は、本発明の建具の第２実施形態を示している。本建具は、図５に示すように、外障子６の上框２１は、上枠８の外レール９の室外側のみに外レール９に当接する軟質ヒレ１０を有し、内障子７の上框２１は、上枠８の内レール１１の室内側のみに内レール１１に当接する軟質ヒレ１２を有している。各軟質ヒレ１０，１２は、上框２１と一体に設けてある。
また、図６に示すように、外障子６の戸先６ａは、室内側から見て左側の縦枠３ａの内周側面に当接しており、当該縦枠３ａは外障子６の戸先部の室内側面に当接する軟質ヒレ３０ａを有している。内障子７の戸先７ａは、室内側から見て右側の縦枠３ｂの内周側面に当接しており、当該縦枠３ｂは内障子７の戸先部の室外側面に当接する軟質ヒレ３０ｂを有している。 4-6 has shown 2nd Embodiment of the fittings of this invention. In this fitting, as shown in FIG. 5, the upper frame 21 of the outer shoji 6 has a soft fin 10 that abuts against the outer rail 9 only on the outer side of the outer rail 9 of the upper frame 8, and The frame 21 has a soft fin 12 that comes into contact with the inner rail 11 only on the indoor side of the inner rail 11 of the upper frame 8. Each of the soft fins 10 and 12 is provided integrally with the upper frame 21.
As shown in FIG. 6, the door tip 6a of the shoji screen 6 is in contact with the inner peripheral side surface of the vertical frame 3a on the left side as viewed from the indoor side, and the vertical frame 3a is the door tip part of the shoji screen 6. It has a soft fin 30a that comes into contact with the indoor side surface of the. The door tip 7a of the inner shoji 7 contacts the inner peripheral side surface of the vertical frame 3b on the right side when viewed from the indoor side, and the vertical frame 3b contacts the outdoor side surface of the door tip of the inner shoji 7 soft fin 30b. have.

図７（ａ）は、内窓２に正圧がかかったとき（図中の矢印２６参照）の状態を示している。このとき、外障子６と内障子７は正圧に押されて室内側に若干移動し、内障子７の上框２１の軟質ヒレ１２が上枠８の内レール１１から離れ、図中の矢印２７に示すように中間層側から室内側に向かって空気が流れる。同時に、図８（ｂ）に示すように、内障子７が室内側に移動するのに伴い、内障子７の戸先部が縦枠３ｂの軟質ヒレ３０ｂから離れ、図中の矢印２７に示すように、中間層側から室内側に向かって空気が流れる。これにより、中間層５の圧力が逃げ、中間層５が室内と等圧になる。
図７（ｂ）は、内窓２に負圧がかかったとき（図中の矢印２８参照）の状態を示している。このとき、外障子６と内障子７は負圧に引っ張られて室外側に若干移動し、外障子６の上框２１の軟質ヒレ１０が上枠８の外レール９から離れ、図中の矢印２９に示すように室内側から中間層側に向かって空気が流れる。同時に、図８（ａ）に示すように、外障子６が室外側に移動するのに伴い、外障子６の戸先部が縦枠３ａの軟質ヒレ３０ａから離れ、図中の矢印２９に示すように、室内側から中間層側に向かって空気が流れる。これにより、中間層５の圧力が逃げ、中間層５が室内と等圧になる。 FIG. 7A shows a state when positive pressure is applied to the inner window 2 (see arrow 26 in the figure). At this time, the outer shoji 6 and the inner shoji 7 are pushed by the positive pressure and slightly move to the indoor side, and the soft fin 12 of the upper frame 21 of the inner shoji 7 is separated from the inner rail 11 of the upper frame 8, and is indicated by an arrow in the figure. As shown by 27, air flows from the intermediate layer side toward the indoor side. At the same time, as shown in FIG. 8(b), as the inner shoji 7 moves to the indoor side, the door tip portion of the inner shoji 7 separates from the soft fin 30b of the vertical frame 3b and is shown by an arrow 27 in the figure. Thus, air flows from the intermediate layer side toward the indoor side. As a result, the pressure of the intermediate layer 5 escapes, and the intermediate layer 5 becomes an equal pressure in the room.
FIG. 7B shows a state when negative pressure is applied to the inner window 2 (see arrow 28 in the figure). At this time, the external shoji 6 and the internal shoji 7 are pulled by the negative pressure and slightly move to the outside of the room, and the soft fin 10 of the upper frame 21 of the external shoji 6 is separated from the outer rail 9 of the upper frame 8, and the arrow in the figure shows. As indicated by 29, air flows from the indoor side toward the intermediate layer side. At the same time, as shown in FIG. 8(a), as the shoji screen 6 moves to the outside of the room, the door tip of the shoji screen 6 separates from the soft fin 30a of the vertical frame 3a and is indicated by an arrow 29 in the figure. Thus, the air flows from the indoor side toward the intermediate layer side. As a result, the pressure of the intermediate layer 5 escapes, and the intermediate layer 5 becomes an equal pressure in the room.

以上に述べたように本建具は、外障子６は、枠（上枠）８の外レール９の室外側のみに外レール９に当接する軟質ヒレ１０を有し、内障子７は、枠（上枠）８の内レール１１の室内側のみに内レール１１に当接する軟質ヒレ１２を有し、外窓・内窓間の中間層５と室内との圧力差により、外障子６が室外側に移動して軟質ヒレ１０が外レール９から離れるか、内障子７が室内側に移動して軟質ヒレ１２が内レール１１から離れることで、中間層５の圧力を逃がすので、強風時に内窓２を閉め切ったままでも、内窓２が変形したり破損したりすることを防止できる。
本建具は、外障子６に枠８の外レール９の室外側のみに外レール９に当接する軟質ヒレ１０を設け、内障子７に枠８の内レール１１の室内側のみに内レール１１に当接する軟質ヒレ１２を設けるだけなので、容易に実施できる。なお、当初は外障子６に外レール９の室外側と室内側の両方に外レール９に当接する軟質ヒレを設け、内障子７に内レール１１の室外側と室内側の両方に内レール１１に当接する軟質ヒレを設けておき、後から外障子６の室内側の軟質ヒレを切除し、内障子７の室外側の軟質ヒレを切除してもよい。 As described above, in the present fitting, the outer shoji 6 has the soft fin 10 that abuts on the outer rail 9 only on the outer side of the outer rail 9 of the frame (upper frame) 8, and the inner shoji 7 has the frame ( The upper frame 8 has a soft fin 12 only on the inner side of the inner rail 11 that abuts against the inner rail 11. Due to the pressure difference between the middle layer 5 between the outer window and the inner window and the room, the outer shoji 6 is placed outside the room.

As shown in, the shutter 45 is normally held at a position higher than the ventilating portion 31, and the air is always allowed to flow through the ventilating portion 31 while being shielded.

内窓２に正圧がかかると、図２４（ａ）中の矢印２７に示すように、通気部３１を中間層側から室内側に向けて空気が流れ、中間層５の圧力を逃がす。内窓２に負圧がかかると、通気部３１を室内側から中間層側に向けて空気が流れ、中間層５の圧力を逃がす。したがって、強風時に内窓２を閉め切ったままでも、内窓２が変形したり破損したりすることを防止できる。
火災が発生すると、図２４（ｂ）に示すように、保持ブロック４７が溶融することでシャッター４５が下降し、シャッター４５が通気部３１を塞ぐ。これにより、火炎や煙が通気部３１を通過するのを防ぐことができ、防火性能を有するものとなる。 When a positive pressure is applied to the inner window 2, as shown by an arrow 27 in FIG. 24( a ), air flows through the ventilation part 31 from the intermediate layer side toward the indoor side, and the pressure of the intermediate layer 5 is released. When a negative pressure is applied to the inner window 2, air flows through the ventilation part 31 from the indoor side toward the intermediate layer side, and the pressure of the intermediate layer 5 is released. Therefore, it is possible to prevent the inner window 2 from being deformed or damaged even when the inner window 2 is completely closed during strong wind.
When a fire occurs, as shown in FIG. 24( b ), the holding block 47 melts and the shutter 45 descends, and the shutter 45 closes the ventilation part 31. As a result, it is possible to prevent flames and smoke from passing through the ventilation section 31 and to have fireproof performance.
