Description

本開示は、内窓に関する。詳しくは、二重窓における外窓の屋内側に配置される内窓に関する。 This disclosure relates to an inner window. More specifically, the present invention relates to an inner window arranged on the indoor side of the outer window in a double-glazed window.

従来、建物の開口部に、内窓と外窓とが二重に設けられて構成される二重窓が知られている（例えば、特許文献１参照）。二重窓は、窓を二重にすることで、断熱性能を高めることができると共に、防音性を高くすることができる。二重窓は、新築時に外窓と内窓とを同時に設けることや、既設の窓の屋内側に、リフォームにより内窓を追加することで設けることもできる。 Conventionally, there is known a double-glazed window in which an inner window and an outer window are doubly provided at an opening of a building (see, for example, Patent Document 1). The double-glazed window can improve the heat insulating performance and the soundproofing property by making the window double. Double-glazed windows can be installed at the same time as an outer window and an inner window at the time of new construction, or by adding an inner window by remodeling to the indoor side of the existing window.

屋内側に配置される内窓は、上枠を有する枠体と、枠体内に配置される障子と、を有する。上枠には、下方に突出する下方突出レールが形成されている。障子の上端部には、上枠の下方突出レールを収容するレール収容ガイドが形成されている。上枠の下方突出レールが、障子のレール収容ガイドに収容されてガイドされることで、障子は、枠体内を見付方向の左右方向にスライド移動可能である。 The inner window arranged on the indoor side has a frame body having an upper frame and a shoji screen arranged in the frame body. The upper frame is formed with a downward projecting rail that projects downward. At the upper end of the shoji, a rail accommodating guide for accommodating the downward protruding rail of the upper frame is formed. The downward protruding rail of the upper frame is accommodated and guided by the rail accommodating guide of the shoji, so that the shoji can slide and move in the left-right direction in the finding direction inside the frame.

One is provided at the corresponding position, and one is provided at the position corresponding to the center in the left-right direction when the internal sash 3 is positioned at the fully open open position located on the opposite side of the closed position in the slide movement direction. .. For example, one shoji retaining member 7 is provided at a position corresponding to the center in the left-right direction when the shoji 4 is positioned in the closed position on the upper frame downward protruding rail 213 for the shoji, and the shoji 4 is provided. One is provided at a position corresponding to the center in the left-right direction when it is located in a fully open open position located on the opposite side of the closed position in the slide moving direction.

障子外れ止め部材７は、図５に示すように、内障子用上枠下方突出レール２１２又は外障子用上枠下方突出レール２１３が延びる左右方向に所定の長さを有して形成される。障子外れ止め部材７は、左右方向に離間する２つのネジ７５により、内障子用上枠下方突出レール２１２又は外障子用上枠下方突出レール２１３の下端部２１２ａ，２１３ａに固定される。 As shown in FIG. 5, the shoji retaining member 7 is formed to have a predetermined length in the left-right direction in which the shoji upper frame downward projecting rail 212 or the shoji upper frame downward projecting rail 213 extends. The shoji retaining member 7 is fixed to the lower end portions 212a and 213a of the upper frame downward protruding rail 212 for internal obstacles or the upper frame downward protruding rail 213 for external obstacles by two screws 75 separated in the left-right direction.

障子外れ止め部材７の下端部７ａの位置は、図２及び図３に示すように、内障子用上枠下方突出レール２１２又は外障子用上枠下方突出レール２１３の下端部２１２ａ，２１３ａよりも所定高さ下方側に位置する。障子外れ止め部材７の下端部７ａの位置は、経年劣化などで、窓枠２の下方突出レール（内障子用上枠下方突出レール２１２及び外障子用上枠下方突出レール２１３）と障子（内障子３、外障子４）との掛かりが少なくなったとしても、障子外れ止め部材７の下端部７ａが障子（内障子３、外障子４）に引っ掛かって、障子（内障子３、外障子４）が窓枠２から外れることを防止できる位置が設定される。 As shown in FIGS. 2 and 3, the position of the lower end portion 7a of the shoji retaining member 7 is higher than the lower end portions 212a and 213a of the upper frame downward projecting rail 212 for internal shoji or the upper frame downward projecting rail 213 for external shoji. It is located on the lower side of the predetermined height. The position of the lower end 7a of the shoji retaining member 7 is due to deterioration over time, etc. Even if the amount of contact with the shoji 3 and the outer shoji 4) is reduced, the lower end 7a of the shoji retaining member 7 is caught by the shoji (inner shoji 3, outer shoji 4) and the shoji (inner shoji 3, outer shoji 4) is caught. ) Is set at a position where it can be prevented from coming off the window frame 2.

そのため、経年劣化などで、障子（内障子３、外障子４）の掛かりが少なくなったとしても、障子外れ止め部材７の下端部７ａは、障子（内障子３、外障子４）の上部レールガイド３１２，４１２に引っ掛かりやすく、内障子３が窓枠２から外れることを防止できる。 Therefore, even if the shoji (inner shoji 3, outer shoji 4) is less likely to be hooked due to deterioration over time, the lower end 7a of the shoji retaining member 7 is the upper rail of the shoji (inner shoji 3, outer shoji 4). It is easy to get caught in the guides 312 and 412, and it is possible to prevent the shoji screen 3 from coming off the window frame 2.

障子外れ止め部材７は、図５に示すように、左右方向の両端部が、それぞれ、左右方向の外側に向かうに従って先細りした形状に形成される。具体的には、障子外れ止め部材７の左右方向の両端部は、それぞれ、左右方向の外側に向かうに従って幅が狭くなる形状に形成され、且つ、左右方向の外側に向かうに従って内障子用上枠下方突出レール２１２又は外障子用上枠下方突出レール２１３の下端部２１２ａ，２１３ａからの高さが徐々に小さくなる形状に形成される。これにより、人が触った場合の安全性を確保できる。また、障子外れ止め部材７が振れ止め部材６の係合パッキン板６３の凹部６３１を掻き分けて移動されるため、内障子３又は外障子４をスムーズに移動させることができる。 As shown in FIG. 5, the shoji retaining member 7 is formed so that both ends in the left-right direction are tapered toward the outside in the left-right direction. Specifically, both ends of the shoji retaining member 7 in the left-right direction are formed in a shape in which the width becomes narrower toward the outside in the left-right direction, and the upper frame for the inner shoji is formed toward the outside in the left-right direction. It is formed in a shape in which the height from the lower end portions 212a and 213a of the lower protruding rail 212 or the lower protruding rail 213 for the upper frame for shoji is gradually reduced. This makes it possible to ensure safety when a person touches it. Further, since the shoji shoji retaining member 7 is moved by scraping the recess 631 of the engaging packing plate 63 of the steady rest member 6, the internal shoji 3 or the external shoji 4 can be smoothly moved.

上枠屋内側下方延出壁部２１４は、図２及び図３に示すように、内障子３の屋内側に配置され、上枠上面板部２１１における屋内側の見込方向の端部から、下方に所定長さ延出する。本実施形態においては、上枠屋内側下方延出壁部２１４の下端部２１４ａは、内障子用上枠下方突出レール２１２の下端部２１２ａ及び外障子用上枠下方突出レール２１３の下端部２１３ａよりも上方側に位置する。 As shown in FIGS. 2 and 3, the lower extending wall portion 214 on the indoor side of the upper frame is arranged on the indoor side of the shoji screen 3, and is downward from the end portion of the upper frame upper plate portion 211 on the indoor side in the prospective direction.

振れ止め部材６には、振れ止め部材本体６１の一対の垂直面部６１２又は一対の傾斜面部６１３の間に内障子用上枠下方突出レール２１２が配置されることで、内障子用上枠下方突出レール２１２が配置される。これにより、内障子３が窓枠２内を見付け方向にスライド移動する際において、内障子３の屋内外方向の移動が規制され、内障子３と窓枠２とのガタつきが抑制される。 The steady rest member 6 is provided with the inner shoji upper frame downward projecting rail 212 between the pair of vertical surface portions 612 or the pair of inclined surface portions 613 of the steady rest member main body 61, so that the inner shoji upper frame downward protrusion Rail 212 is arranged. As a result, when the sash 3 slides in the window frame 2 in the finding direction, the movement of the sash 3 in the indoor / outdoor direction is restricted, and the rattling between the sash 3 and the window frame 2 is suppressed.

内障子３が移動されて、振れ止め部材６が障子外れ止め部材７が配置された位置に移動した場合には、上部レールガイド３１２，４１２に障子外れ止め部材７が配置された位置に移動した場合と同様に、経年劣化などで、窓枠２と障子（内障子３、外障子４）との掛かりが少なくなったとしても、下方突出レール（内障子用上枠下方突出レール２１２及び外障子用上枠下方突出レール２１３）の下端部２１２ａ，２１３ａに障子外れ止め部材７が取り付けられているため、障子外れ止め部材７の下端部７ａは、振れ止め部材６に引っ掛かりやすく、内障子３が窓枠２から外れることを防止できる。 When the internal obstacle 3 was moved and the steady rest member 6 moved to the position where the obstacle retaining member 7 was arranged, it moved to the position where the obstacle retaining member 7 was arranged on the upper rail guides 312 and 412. As in the case, even if the window frame 2 and the shoji (inner shoji 3 and outer shoji 4) are less engaged due to deterioration over time, the downward protruding rail (upper frame lower protruding rail 212 for the inner shoji and the outer shoji) Since the shoji retaining member 7 is attached to the lower ends 212a and 213a of the upper frame downward protruding rail 213), the lower end 7a of the shoji retaining member 7 is easily caught by the steady rest member 6 and the internal obstacle 3 is attached. It is possible to prevent the window frame 2 from coming off.

次に、内窓１の施工手順について説明する。内窓１の施工時において、内障子３及び外障子４を窓枠２に組み込む場合について説明する。内障子３及び外障子４を、窓枠２内に、いわゆるケンドン式にて組み込んで建て込む。 Next, the construction procedure of the inner window 1 will be described. A case where the inner sash 3 and the outer sash 4 are incorporated into the window frame 2 at the time of construction of the inner window 1 will be described. The internal shoji 3 and the external shoji 4 are built in the window frame 2 by incorporating them in a so-called Kendon style.

外障子４をケンドン式で窓枠２に組み込む場合には、外障子４の上部を内窓１の窓枠２の内部側に傾けて、外障子４を徐々に立てながら、上方側に持ち上げて、外障子４の上部レールガイド４１２を上枠２１の外障子用上枠下方突出レール２１３に挿入して、上方側に更に持ち上げた後に、下方側に下ろすことで、外障子４の戸車３２１を下枠２２の外障子用下部レール２２２に挿入する。内障子３をケンドン式で窓枠２に組み込む場合には、内障子３の上部を内窓１の窓枠２の内部側に傾けて、内障子３を徐々に立てながら、上方側に持ち上げて、内障子３の上部レールガイド３１２を上枠２１の内障子用上枠下方突出レール２１２に挿入して、上方側に更に持ち上げた後に、下方側に下ろすことで、内障子３の戸車３２１を下枠２２の内障子用下部レール２２１に挿入する。 When the shoji 4 is incorporated into the window frame 2 by the Kendon method, the upper part of the shoji 4 is tilted toward the inside of the window frame 2 of the inner window 1, and the shoji 4 is gradually raised and lifted upward. , The upper rail guide 412 of the outer sash 4 is inserted into the upper frame downward protruding rail 213 for the outer sash of the upper frame 21, lifted further upward, and then lowered to the lower side to lower the door roller 321 of the outer sash 4. It is inserted into the lower rail 222 for the shoji of the lower frame 22. When incorporating the shoji 3 into the window frame 2 in a Kendon style, the upper part of the shoji 3 is tilted toward the inside of the window frame 2 of the inner window 1, and the shoji 3 is gradually raised and lifted upward. , The upper rail guide 312 of the inner sash 3 is inserted into the upper frame downward protruding rail 212 for the inner sash of the upper frame 21, and after being further lifted upward, it is lowered to the lower side to lower the door roller 321 of the inner sash 3. It is inserted into the lower rail 221 for the inner shoji of the lower frame 22.

その後、内障子３の上端の左右方向の端部において、振れ止め部材６を、内障子３と上枠２１の内障子用上枠下方突出レール２１２との掛かりが適正になるよう調整を行う。外障子４の上端の左右方向の端部において、振れ止め部材６を、外障子４と上枠２１の外障子用上枠下方突出レール２１３との掛かりが適正になるよう調整を行う。 After that, at the left-right end of the upper end of the inner sash 3, the steady rest member 6 is adjusted so that the inner sash 3 and the upper frame downward projecting rail 212 for the inner sash of the upper frame 21 are properly engaged. At the left-right end of the upper end of the outer sash 4, the steady rest member 6 is adjusted so that the outer sash 4 and the upper frame 21 upper frame downward projecting rail 213 are properly engaged.

ここで、上部レールガイド３１２，４１２は、内障子３及び外障子４を、窓枠２内に、いわゆるケンドン式にて組み込む場合に、内障子用上枠下方突出レール２１２及び外障子用上枠下方突出レール２１３を収容可能である。一方、下方突出レール（内障子用上枠下方突出レール２１２及び外障子用上枠下方突出レール２１３）の下端部２１２ａ，２１３ａに障子外れ止め部材７を取り付けた場合には、障子外れ止め部材７を取り付けた位置においては、障子外れ止め部材７が邪魔になって、内障子３及び外障子４を、窓枠２内に、いわゆるケンドン式にて組み込む場合に、上部レールガイド３１２，４１２には、内障子用上枠下方突出レール２１２及び外障子用上枠下方突出レール２１３を収容できない。 Here, the upper rail guides 312 and 412 include the upper frame downward protruding rail 212 for the inner sash and the upper frame for the outer sash when the inner sash 3 and the outer sash 4 are incorporated into the window frame 2 by the so-called Kendon method. It can accommodate the downward protruding rail 213. On the other hand, when the shoji retaining member 7 is attached to the lower ends 212a and 213a of the downward projecting rail (upper frame downward projecting rail 212 for internal shoji and lower projecting rail 213 for external shoji), the shoji retaining member 7 At the position where the shoji is attached, the shoji retaining member 7 becomes an obstacle, and when the shoji 3 and the shoji 4 are incorporated into the window frame 2 by the so-called Kendon method, the upper rail guides 312 and 412 , The upper frame downward projecting rail 212 for internal shoji and the upper frame downward projecting rail 213 for external shoji cannot be accommodated.

そのため、本実施形態においては、障子外れ止め部材７を、内障子３又は外障子４をスライド移動させることで、内障子３又は外障子４が配置されない位置であって内障子３又は外障子４がスライド移動されて配置されることが可能な位置において、内障子用上枠下方突出レール２１２又は外障子用上枠下方突出レール２１３の下端部２１２ａ，２１３ａに固定する。 Therefore, in the present embodiment, the shoji retaining member 7 is moved by sliding the shoji 3 or the shoji 4, so that the shoji 3 or the shoji 4 is not placed at the position where the shoji 3 or the shoji 4 is not arranged. Is fixed to the lower end portions 212a, 213a of the upper frame downward projecting rail 212 for internal shoji or the upper frame downward projecting rail 213 for external shoji at a position where the sliding door can be slid and arranged.

As shown in FIG. 5, the shoji retaining member 7 is fixed to 213a by a screw 75. After that, the internal sash 3 and the external sash 4 are slid to the position where the sash retaining member 7 is attached.

また、窓枠２内に内障子３又は外障子４を建て込む前において、障子外れ止め部材７を、内障子用上枠下方突出レール２１２又は外障子用上枠下方突出レール２１３の下端部２１２ａ，２１３ａに、障子外れ止め部材７をネジ７５により固定してもよい。その後、障子外れ止め部材７を取り付けた位置を避けた位置において、窓枠２内に内障子３又は外障子４を建て込んで、障子外れ止め部材７を取り付けた位置に、内障子３及び外障子４をスライド移動させる。 Further, before the internal sash 3 or the external sash 4 is built in the window frame 2, the sash retaining member 7 is attached to the lower end portion 212a of the internal sash upper frame downward protrusion rail 212 or the external sash upper frame downward protrusion rail 213. The shoji retaining member 7 may be fixed to the 213a with a screw 75. After that, the inner sash 3 or the outer sash 4 is built in the window frame 2 at a position avoiding the position where the sash removal prevention member 7 is attached, and the inner sash 3 and the outside are at the position where the sash removal prevention member 7 is attached. Slide the shoji 4 to move.

このように、本実施形態においては、障子外れ止め部材７を、内障子用上枠下方突出レール２１２及び外障子用上枠下方突出レール２１３の下端部２１２ａ，２１３ａに取り付けている。そのため、経年劣化などで、窓枠２と障子（内障子３、外障子４）との掛かりが少なくなったとしても、内障子３及び外障子４は、障子外れ止め部材７が邪魔になって、窓枠２から外れにくい。よって、障子（内障子３、外障子４）が窓枠２から外れることを防止できる。 As described above, in the present embodiment, the shoji retaining member 7 is attached to the lower ends 212a and 213a of the upper frame downward projecting rail 212 for the internal shoji and the upper frame downward projecting rail 213 for the external obstacle. Therefore, even if the window frame 2 and the shoji (inner shoji 3 and outer shoji 4) are less likely to be engaged due to deterioration over time, the shoji retaining member 7 becomes an obstacle in the inner shoji 3 and the outer shoji 4. , It is hard to come off from the window frame 2. Therefore, it is possible to prevent the shoji (inner shoji 3, outer shoji 4) from coming off the window frame 2.

本実施形態によれば、以下の効果が奏される。本実施形態の内窓１は、窓枠２内に配置され横方向にスライド移動可能な障子（内障子３，外障子４）と、を備え、上枠２１は、下方に突出する下方突出レール（内障子用上枠下方突出レール２１２，外障子用上枠下方突出レール２１３）を有し、障子（内障子３，外障子４）は、上方に向けて開放すると共に下方突出レール（内障子用上枠下方突出レール２１２，外障子用上枠下方突出レール２１３）の少なくとも一部を収容して障子（内障子３，外障子４）の横方向へのスライド移動をガイドするレール収容ガイド部（上部レールガイド３１２，４１２、振れ止め部材６）を有し、下方突出レール（内障子用上枠下方突出レール２１２，外障子用上枠下方突出レール２１３）の下端部２１２ａ，２１３ａには、障子（内障子３，外障子４）のスライド移動の移動範囲の一部において、下方突出レール（内障子用上枠下方突出レール２１２，外障子用上枠下方突出レール２１３）を下方に延長するように取り付け可能な障子外れ止め部材７が取り付けられる。 According to this embodiment, the following effects are achieved. The inner window 1 of the present embodiment includes a shoji (inner shoji 3, outer shoji 4) arranged in the window frame 2 and slidable in the lateral direction, and the upper frame 21 is a downward protruding rail protruding downward. It has (upper frame downward projecting rail 212 for internal shoji, upper frame downward projecting rail 213 for external shoji), and the shoji (internal shoji 3, external shoji 4) is opened upward and downward projecting rail (internal shoji). Rail accommodating guide unit that accommodates at least a part of the upper frame downward projecting rail 212 and the external shoji upper frame downward projecting rail 213) and guides the lateral slide movement of the shoji (inner shoji 3, outer shoji 4). (Upper rail guides 312, 412, steady rest member 6) are provided, and the lower end portions 212a, 213a of the downward projecting rails (upper frame downward projecting rail 212 for internal shoji, upper frame downward projecting rail 213 for external shoji) In a part of the movement range of the sliding movement of the shoji (inner shoji 3, outer shoji 4), the downward projecting rail (upper frame downward projecting rail 212 for internal shoji, upper frame downward projecting rail 213 for external shoji) is extended downward. The shoji retaining member 7 that can be attached is attached.

これにより、経年劣化などで、窓枠２と障子（内障子３、外障子４）との掛かりが少なくなったとしても、下方突出レール（内障子用上枠下方突出レール２１２及び外障子用上枠下方突出レール２１３）の下端部２１２ａ，２１３ａに障子外れ止め部材７が取り付けられているため、障子外れ止め部材７が邪魔になって、障子（内障子３、外障子４）が窓枠２から外れることを防止できる。 As a result, even if the engagement between the window frame 2 and the shoji (inner shoji 3 and outer shoji 4) is reduced due to deterioration over time, the lower protruding rail (upper frame lower protruding rail 212 for the inner shoji and the upper shoji for the outer shoji). Since the shoji retaining member 7 is attached to the lower ends 212a and 213a of the frame downward projecting rail 213), the shoji retaining member 7 becomes an obstacle and the shoji (inner shoji 3 and outer shoji 4) becomes the window frame 2. It can be prevented from coming off from.
