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.

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、突出移動機構部７の上下方向移動板７１を退避位置（図４における二点鎖線の位置）に位置させた状態で、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 inner sash 3 and the outer sash 4 are placed in the window frame 2 in a so-called Kendon style with the vertical movement plate 71 of the protrusion movement mechanism 7 positioned at the retracted position (the position of the alternate long and short dash line in FIG. 4). Build in and build.

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.

続けて、突出移動機構部７の２つのネジ７３，７３を緩めて、上下方向移動板７１を、スリット開口７１１に沿って上方側に移動させて突出位置で固定する。これにより、図３に示すように、上下方向移動板７１を、上枠２１の上枠屋内側下方延出壁部２１４や内障子用上枠下方突出レール２１２に引っ掛かる位置まで上方側に移動させることができる。 Subsequently, the two screws 73, 73 of the protrusion movement mechanism portion 7 are loosened, and the vertical movement plate 71 is moved upward along the slit opening 711 and fixed at the protrusion position. As a result, as shown in FIG. 3, the vertical moving plate 71 is moved upward to a position where it is hooked on the upper frame indoor side downward extending wall portion 214 of the upper frame 21 and the upper frame downward protruding rail 212 for internal shoji. be able to.

上下方向移動板７１の上端部７１２の位置は、内障子３の上端よりも所定高さ上部側に位置する。上下方向移動板７１の上端部７１２の位置は、経年劣化などで、窓枠２の内障子用上枠下方突出レール２１２と内障子３との掛かりが少なくなったとしても、上下方向移動板７１の上端部７１２が窓枠２の内障子用上枠下方突出レール２１２の下端部２１２ａ又は上枠屋内側下方延出壁部２１４の下端部２１４ａに引っ掛かって、内障子３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。 The position of the upper end portion 712 of the vertical movement plate 71 is located on the upper side of a predetermined height with respect to the upper end portion of the internal sash 3. The position of the upper end portion 712 of the vertical moving plate 71 is such that the vertical moving plate 71 is less likely to be engaged with the lower protruding rail 212 for the inner shoji of the window frame 2 due to deterioration over time. The upper end portion 712 of the window frame 2 is caught by the lower end portion 212a of the upper frame downward projecting rail 212 for the inner shoji of the window frame 2 or the lower end portion 214a of the lower extending wall portion 214 on the indoor side of the upper frame, and the inner shoji 3 is disengaged from the window frame 2. A position that can prevent this is set.

そのため、経年劣化などで、内障子３の掛かりが少なくなったとしても、上下方向移動板７１は、上枠２１の上枠屋内側下方延出壁部２１４や内障子用上枠下方突出レール２１２に引っ掛かりやすく、内障子３が倒れることを防止できる。 Therefore, even if the hanging of the internal shoji 3 is reduced due to deterioration over time, the vertical moving plate 71 can be used for the upper frame 21 upper frame indoor side downward extending wall portion 214 and the inner shoji upper frame downward protruding rail 212. It is easy to get caught in the sash, and it is possible to prevent the shoji screen 3 from falling over.

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、障子（内障子３，外障子４）は、障子（内障子３，外障子４）の上端部よりも上方側に突出する突出位置に移動可能な突出移動機構部７を備える。 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) that is arranged in the window frame 2 and can be slid laterally, and the upper frame 21 is a downward protruding rail that protrudes 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). It has (upper rail guides 312, 412, steady rest member 6), and the shoji (inner shoji 3, outer shoji 4) protrudes upward from the upper end of the shoji (inner shoji 3, outer shoji 4). A protrusion movement mechanism unit 7 that can be moved to a position is provided.

これにより、上下方向移動板７１を、上枠２１の上枠屋内側下方延出壁部２１４や内障子用上枠下方突出レール２１２に引っ掛かる位置まで上方側に移動させることができる。上下方向移動板７１の上端部７１２は、内障子３の上端よりも上部側に位置する。そのため、経年劣化などで、窓枠２の内障子用上枠下方突出レール２１２と内障子３との掛かりが少なくなったとしても、上下方向移動板７１は、上枠２１の上枠屋内側下方延出壁部２１４や内障子用上枠下方突出レール２１２に引っ掛かりやすく、内障子３が倒れることを防止できる。 As a result, the vertical moving plate 71 can be moved upward to a position where it is caught by the upper frame indoor side downward extending wall portion 214 of the upper frame 21 and the upper frame downward protruding rail 212 for internal shoji. The upper end portion 712 of the vertical movement plate 71 is located on the upper side of the upper end portion of the internal sash 3. Therefore, even if the engagement between the lower protruding rail 212 for the upper frame for the inner sash of the window frame 2 and the inner sash 3 is reduced due to deterioration over time, the vertical movement plate 71 is below the upper frame indoor side of the upper frame 21. It is easy to get caught in the extending wall portion 214 or the lower protruding rail 212 for the upper frame for the internal sash, and the internal sash 3 can be prevented from falling.

本実施形態においては、突出移動機構部７は、障子（内障子３，外障子４）の上端部よりも上方側にスライド移動可能に障子（内障子３，外障子４）に設けられる。これにより、突出移動機構部７の上下方向移動板７１をスライド移動させることで、突出移動機構部７の上下方向移動板７１を容易に上方側に移動させて、内障子３が倒れることを容易に防止できる。 In the present embodiment, the protruding movement mechanism portion 7 is provided on the shoji (inner shoji 3, outer shoji 4) so as to be slidable upward from the upper end portion of the shoji (inner shoji 3, outer shoji 4). As a result, by sliding the vertical movement plate 71 of the protrusion movement mechanism portion 7, the vertical movement plate 71 of the protrusion movement mechanism portion 7 can be easily moved upward, and the internal shoji 3 can be easily collapsed. Can be prevented.

次に、第２実施形態について説明する。第２実施形態は、第１実施形態の変形形態であり、第１実施形態の突出移動機構部７に代えて、突出移動機構部８を備える。第２実施形態のその他の構成は、第１実施形態の構成と同様である。第２実施形態の説明において、第１実施形態と同様の構成については、説明を省略する場合がある。 Next, the second embodiment will be described. The second embodiment is a modified form of the first embodiment, and includes a protruding movement mechanism unit 8 instead of the protruding movement mechanism unit 7 of the first embodiment. The other configurations of the second embodiment are the same as the configurations of the first embodiment. In the description of the second embodiment, the description of the same configuration as that of the first embodiment may be omitted.

第２実施形態の突出移動機構部８について説明する。図５及び図６に示すように、第２実施形態の突出移動機構部８は、内障子３に設けられた振れ止め部材６の一対の上部板６２，６２のうちの屋外側の上部板６２ａの上面に設けられる。 The protrusion movement mechanism portion 8 of the second embodiment will be described. As shown in FIGS. 5 and 6, the protrusion movement mechanism portion 8 of the second embodiment is the outdoor side upper plate 62a of the pair of upper plates 62, 62 of the steady rest member 6 provided on the internal sash 3. It is provided on the upper surface of the.

突出移動機構部８は、固定板８１と、上側移動板８２と、付勢部８３と、を備える。固定板８１は、振れ止め部材６の一対の上部板６２，６２のうちの屋外側の上部板６２ａの上面に沿って形成された板状に形成される。固定板８１は、振れ止め部材６の屋外側の上部板６２ａの上面に固定される。 The protrusion moving mechanism portion 8 includes a fixing plate 81, an upper moving plate 82, and an urging portion 83. The fixing plate 81 is formed in a plate shape formed along the upper surface of the upper plate 62a on the outdoor side of the pair of upper plates 62, 62 of the steady rest member 6. The fixing plate 81 is fixed to the upper surface of the upper plate 62a on the outdoor side of the steady rest member 6.

上側移動板８２は、固定板８１の見付方向の左右方向の外側の端部に付勢部８３を介して接続される。上側移動板８２は、内障子３の上端よりも上方側の突出位置（図６における実線の位置）と、突出位置よりも下方側の位置であって内障子３を窓枠２に建て込む際に位置させる退避位置（図５における二点鎖線の位置）と、に移動可能に構成される。 The upper moving plate 82 is connected to the outer end of the fixing plate 81 in the left-right direction in the finding direction via the urging portion 83. The upper moving plate 82 is located at a protruding position above the upper end of the internal sash 3 (the position of the solid line in FIG. 6) and a position below the protruding position when the internal sash 3 is built in the window frame 2. It is configured to be movable to the retracted position (the position of the alternate long and short dash line in FIG. 5).

付勢部８３は、上側移動板８２を突出位置側に付勢する。内障子３を窓枠２に建て込む場合には、上側移動板８２を付勢部８３の付勢力に抗して固定板８１側へ手で押圧しながら建て込む。そして、内障子３を窓枠２に建て込んだ後に、上側移動板８２から手を離すことで、上側移動板８２を付勢部８３の付勢力により、突出位置に移動させることができる。これにより、突出移動機構部８は、内障子３の上端部よりも上方側に突出する側に立ち上がるように付勢される。 The urging portion 83 urges the upper moving plate 82 toward the protruding position. When the internal shoji 3 is built in the window frame 2, the upper moving plate 82 is built while being manually pressed toward the fixed plate 81 against the urging force of the urging portion 83. Then, after the internal shoji 3 is built in the window frame 2, the upper moving plate 82 can be moved to the protruding position by the urging force of the urging portion 83 by releasing the hand from the upper moving plate 82. As a result, the protruding movement mechanism portion 8 is urged to stand up on the side protruding upward from the upper end portion of the internal sash 3.

第２実施形態においては、内障子３及び外障子４を窓枠２に組み込む場合に、突出移動機構部８の上側移動板８２を手で押さえた状態で、内障子３及び外障子４を、第１実施形態と同様に、窓枠２内に、いわゆるケンドン式にて組み込む。そして、突出移動機構部８の上側移動板８２から手を離す。これにより、上側移動板８２は、付勢力により上方側に突出する突出位置に移動される。 In the second embodiment, when the internal sash 3 and the external sash 4 are incorporated into the window frame 2, the internal sash 3 and the external sash 4 are held in a state where the upper moving plate 82 of the protruding movement mechanism portion 8 is held by hand. Similar to the first embodiment, it is incorporated in the window frame 2 by a so-called Kendon method. Then, the hand is released from the upper moving plate 82 of the protruding moving mechanism portion 8. As a result, the upper moving plate 82 is moved to a protruding position protruding upward by the urging force.

このようにして、図５に示すように、上側移動板８２を、上枠２１の内障子用上枠下方突出レール２１２に引っ掛かる位置まで上方側に移動させることができる。上側移動板８２の上端部８２１は、内障子３の上端よりも上部側に位置する。そのため、経年劣化などで、内障子３の掛かりが少なくなったとしても、上側移動板８２は、上枠２１の内障子用上枠下方突出レール２１２に引っ掛かりやすく、内障子３が倒れることを防止できる。 In this way, as shown in FIG. 5, the upper moving plate 82 can be moved upward to a position where the upper frame 21 is hooked on the lower protruding rail 212 for the shoji screen. The upper end portion 821 of the upper moving plate 82 is located on the upper side of the upper end of the internal shoji 3. Therefore, even if the sash 3 is less likely to be hooked due to deterioration over time, the upper moving plate 82 is likely to be caught on the lower protruding rail 212 for the sash of the upper frame 21 to prevent the sash 3 from falling over. can.

第２実施形態においても、第１実施形態と同様の効果を奏することができる。具体的には、上側移動板８２を、上枠２１の内障子用上枠下方突出レール２１２に引っ掛かる位置まで上方側に移動させることができる。そのため、経年劣化などで、窓枠２の内障子用上枠下方突出レール２１２と内障子３との掛かりが少なくなったとしても、上側移動板８２は、上枠２１の内障子用上枠下方突出レール２１２に引っ掛かりやすく、内障子３が倒れることを防止できる。 Also in the second embodiment, the same effect as that of the first embodiment can be obtained. Specifically, the upper moving plate 82 can be moved upward to a position where the upper frame 21 is hooked on the lower protruding rail 212 for the shoji screen. Therefore, even if the engagement between the lower protruding rail 212 for the inner shoji of the window frame 2 and the inner shoji 3 is reduced due to deterioration over time, the upper moving plate 82 is below the upper frame for the inner shoji of the upper frame 21. It is easy to get caught on the protruding rail 212, and it is possible to prevent the internal shoji 3 from falling over.

本実施形態においては、突出移動機構部８は、内障子３の上端部よりも上方側に突出する側に立ち上がるように付勢される。これにより、内障子３及び外障子４を窓枠２に組み込んだ後に、上側移動板８２を押さえた状態から手を離すだけで、上側移動板８２を容易に上方側に移動させて、内障子３が倒れることを容易に防止できる。 In the present embodiment, the protruding movement mechanism portion 8 is urged to stand up on the side protruding upward from the upper end portion of the internal sash 3. As a result, after incorporating the inner sash 3 and the outer sash 4 into the window frame 2, the upper sash can be easily moved upward by simply releasing the hand from the state where the upper sash 82 is held. 3 can be easily prevented from falling over.

本実施形態においては、突出移動機構部８は、振れ止め部材６に設けられる。これにより、振れ止め部材６において内障子３の振れを抑制しつつ、振れ止め部材６に設けられた突出移動機構部８において内障子３が倒れることを防止できる。 In the present embodiment, the protrusion movement mechanism portion 8 is provided on the steady rest member 6. As a result, it is possible to prevent the internal sash 3 from falling in the protrusion movement mechanism portion 8 provided on the steady rest member 6 while suppressing the sway of the internal sash 3 in the steady rest member 6.
