Description

本開示は、サッシ構造に関する。 This disclosure relates to sash structures.

従来、採光部を大きく形成した大型の建具が知られている。大型の建具では障子の枚数が増加するので、障子に網戸を設ける場合には、網戸の数も増加する。そこで、複数の網戸を引き違い状に設けたサッシ構造が提案されている(例えば、特許文献1参照)。 Conventionally, large fittings with large lighting sections are known. Large fittings require a large number of shoji screens, and if screen doors are installed on the shoji screens, the number of screen doors also increases. Therefore, a sash structure with multiple sliding screen doors has been proposed (see, for example, Patent Document 1).

特開2017-8600号公報JP 2017-8600 A

通常換気や採風の為に窓を開放する場合、障子を開く操作を行った後に開放した障子に応じて網戸を所定位置に移動することで虫の侵入等を防止する。網戸と障子とが重なる位置がずれると虫が侵入する懸念が生じる。その為、障子及び網戸の枚数が多い場合にはユーザーに非常に煩雑な操作を求めることとなる。 When opening a window to allow ventilation or fresh air, the screen door is usually moved to a designated position in accordance with the opened screen door after the screen door is opened to prevent insects from entering. If the screen door and screen door overlap in a misaligned position, there is a risk of insects entering. Therefore, when there are a large number of screen doors and screen doors, the user is required to carry out very complicated operations.

本開示は、複数の障子と、前記複数の障子の室外側に配置される複数の網戸と、前記複数の網戸のうち室内側の内網戸と、前記複数の障子のうち室外側の外障子とを接続・分離可能な接続部と、を備え、前記内網戸と、前記外障子とは、前記接続部により接続された状態で連動して移動可能なサッシ構造に関する。 The present disclosure relates to a sash structure that includes multiple screen doors, multiple screen doors arranged on the exterior side of the multiple screen doors, and a connection section that can connect and separate an inner screen door on the interior side of the multiple screen doors and an outer screen door on the exterior side of the multiple screen doors, and the inner screen doors and the outer screen doors can move in conjunction with each other while connected by the connection section.

The up-down direction refers to the top-to-bottom direction. With respect to the appearance direction, the outside appearance direction refers to the side closer to the edge of the sliding window 100 in the left-to-right direction, and the inside appearance direction refers to the side closer to the center in the left-to-right direction.

枠体2は、引き違い窓100が配置される略矩形状の開口部201の周囲に矩形状に組まれる枠である。枠体2は、それぞれが長尺状の上枠21と、下枠22(図2参照)と、一対の縦枠23とを有する。 The frame body 2 is a rectangular frame assembled around a substantially rectangular opening 201 in which the sliding window 100 is placed. The frame body 2 has an upper frame 21, a lower frame 22 (see Figure 2), and a pair of vertical frames 23, each of which is elongated.

上枠21は、開口部201の上縁に沿って見付方向に略水平方向に延びるように配置される型材である。上枠21は、下方に向かって突出する複数の障子係合片211と、上側第1レール部212と、を有する。障子係合片211は、上枠21の見込方向に間を空けて3つ下方に突出している。障子係合片211は、上枠21の見付方向の一方から他方まで延びている。障子係合片211は、後述する障子3の上框31に挿入される。上側第1レール部212は、最も室外側に位置する障子係合片211から室外側に離れた位置で下方に向かって突出する。上側第1レール部212は、後述する網戸4が一枚設けられる場合に網戸4が係合する突出部である。上側第1レール部212は、上枠21の見付方向の一方から他方まで延びている。 The upper frame 21 is a molded member arranged to extend approximately horizontally in the front direction along the upper edge of the opening 201. The upper frame 21 has multiple shoji engagement pieces 211 that protrude downward and an upper first rail portion 212. The shoji engagement pieces 211 protrude downward in three pieces at intervals in the front direction of the upper frame 21. The shoji engagement pieces 211 extend from one side of the front direction of the upper frame 21 to the other side. The shoji engagement pieces 211 are inserted into the upper frame 31 of the shoji 3 described later. The upper first rail portion 212 protrudes downward at a position away from the shoji engagement piece 211 located on the outermost side of the room to the outside. The upper first rail portion 212 is a protruding portion that engages with the screen door 4 when one screen door 4 described later is provided. The upper first rail portion 212 extends from one side of the front direction of the upper frame 21 to the other side.

下枠22は、開口部201の下縁に沿って見付方向に略水平方向に延びるように配置される型材である。下枠22は、戸車レール部221と、下側第1レール部222とを有する。戸車レール部221は、下枠22の見込方向に間を空けて3つ配置される。戸車レール部221には、後述する戸車32aが係合して障子3がスライド可能に配置される。下側第1レール部222は、最も室外側に位置する戸車レール部221から室外側に離れた位置で上方に向かって突出する。下側第1レール部222は、後述する網戸4が一枚設けられる場合に網戸4が係合する突出部である。下側第1レール部222は、下枠22の見付方向の一方から他方まで延びている。 The lower frame 22 is a molded member arranged to extend approximately horizontally in the projection direction along the lower edge of the opening 201. The lower frame 22 has a wheel rail section 221 and a lower first rail section 222. Three wheel rail sections 221 are arranged at intervals in the projection direction of the lower frame 22. A wheel 32a (described later) engages with the wheel rail section 221 to allow the shoji screen 3 to slide. The lower first rail section 222 protrudes upward at a position away from the wheel rail section 221 located on the outermost side of the room. The lower first rail section 222 is a protruding section that engages with the screen door 4 when one screen door 4 (described later) is provided. The lower first rail section 222 extends from one side of the lower frame 22 to the other side in the projection direction.

縦枠23は、図1に示すように、開口部201の上下方向に延び、上枠21及び下枠22の両端で、上枠21及び下枠22を接続するように配置される。縦枠23は、見込方向に障子3を3枚配置可能に構成されている。 As shown in FIG. 1, the vertical frame 23 extends in the vertical direction of the opening 201 and is arranged to connect the upper frame 21 and the lower frame 22 at both ends of the upper frame 21 and the lower frame 22. The vertical frame 23 is configured so that three shoji screens 3 can be arranged in the prospective direction.

網戸アタッチメント5は、上枠21及び下枠22が一枚の網戸4のみ取り付け可能な形状の場合に、上枠21及び下枠22に取り付けて、後述する網戸4を引き違い状に配置する部材である。網戸アタッチメント5は、上側アタッチメント51と、下側アタッチメント52と、を有する。 The screen door attachment 5 is a component that is attached to the upper frame 21 and the lower frame 22 when the upper frame 21 and the lower frame 22 are shaped so that only one screen door 4 can be attached, and that arranges the screen door 4 (described later) in a sliding manner. The screen door attachment 5 has an upper attachment 51 and a lower attachment 52.

上側アタッチメント51は、上枠21の前面側に固定され、上枠21の上面に連続する上面51aと、最も室外側で上下方向に延びる前面51bと、を有する。上側アタッチメント51は、前面51bの下端から見込方向室内側に、上枠21の上側第1レール部212と平行に見付方向に延びる上側第2レール部511を有する。 The upper attachment 51 is fixed to the front side of the upper frame 21 and has an upper surface 51a that is continuous with the upper surface of the upper frame 21, and a front surface 51b that extends in the vertical direction on the outermost side of the room. The upper attachment 51 has an upper second rail portion 511 that extends in the forward direction parallel to the upper first rail portion 212 of the upper frame 21 from the lower end of the front surface 51b toward the inside of the room in the forward direction.

下側アタッチメント52は、下枠22の前面側に固定される。下側アタッチメント52は、下枠22から見込方向室外側へ延びる下面52aと、最も室外側で上下方向に延びる前面52bと、を有する。下側アタッチメント52は、前面52bの上端から見込方向室内側に、下枠22の下側第1レール部222と平行に見付方向に延びる下側第2レール部521を有する。 The lower attachment 52 is fixed to the front side of the lower frame 22. The lower attachment 52 has a lower surface 52a extending from the lower frame 22 toward the outside of the room in the forward-looking direction, and a front surface 52b extending in the vertical direction at the outermost side of the room. The lower attachment 52 has a lower second rail portion 521 extending in the forward-looking direction parallel to the lower first rail portion 222 of the lower frame 22 from the upper end of the front surface 52b toward the inside of the room in the forward-looking direction.

上側第1レール部212及び下側第1レール部222によって、室内側に網戸4が移動可能なレールが1本、上側第2レール部511及び下側第2レール部521によって、室外側に網戸4が移動可能なレールが1本、合計2本配置される。これにより、網戸4を室内側と室外側の2本のレールで引き違い状に移動させることが可能になっている。例えば、6枚の障子3のうち、2枚を見付方向の一方、2枚を他方に開いた場合、網戸4は見付方向の内側に連続して4枚配置することができる。6枚の障子3すべてを左右どちらか一方に寄せた場合、残りの開口に4枚の網戸を配置することができる。 The upper first rail section 212 and the lower first rail section 222 provide one rail on the indoor side along which the screen door 4 can move, and the upper second rail section 511 and the lower second rail section 521 provide one rail on the outdoor side along which the screen door 4 can move. This allows the screen door 4 to be moved in a sliding manner on the two rails on the indoor and outdoor sides. For example, if two of the six shoji screens 3 are opened to one side in the viewing direction and two to the other, four screen doors 4 can be placed consecutively on the inside of the viewing direction. If all six shoji screens 3 are moved to either the left or right, four screen doors can be placed in the remaining opening.

上側アタッチメント51及び下側アタッチメント52の見付方向左右端部には、不図示の網戸4の脱落防止部材が設けられる。脱落防止部材は、例えばストッパ部品、又は見込方向室外側に伸びるサッシ枠の張り出しであってよい。網戸4の脱落防止部材を設けることで、網戸4の見付方向左右端部に縦方向に延びるアタッチメントを設けずとも網戸4の脱落を防止することができる。 Members for preventing the screen door 4 from falling off (not shown) are provided on the left and right ends of the upper attachment 51 and the lower attachment 52 in the forward direction. The anti-fall-off member may be, for example, a stopper part or a protrusion of the sash frame extending to the outside of the forward direction. By providing a member for preventing the screen door 4 from falling off, it is possible to prevent the screen door 4 from falling off without providing attachments that extend vertically on the left and right ends of the screen door 4 in the forward direction.

障子3は、枠体2の内側で見付方向に移動自在に6枚配置される。複数の障子3のうち、室外側に配置される障子3を内障子310、室外側に配置される障子3を外障子330、内障子310と外障子330との間に配置される障子3を中障子320と呼ぶ。障子3のそれぞれは、框30と、ガラス部35と、を有する。図1及び図2に示すように、框30は、それぞれが長尺状の上框31、下框32及び一対の縦框33を有する。框30は、内周側に向かって開口した断面視略コの字状に形成される。 Six shoji screens 3 are arranged inside the frame 2 so that they can move freely in the viewing direction. Of the multiple shoji screens 3, the shoji screen 3 arranged on the outside of the room is called the inner shoji screen 310, the shoji screen 3 arranged on the outside of the room is called the outer shoji screen 330, and the shoji screen 3 arranged between the inner shoji screen 310 and the outer shoji screen 330 is called the middle shoji screen 320. Each of the shoji screens 3 has a frame 30 and a glass section 35. As shown in Figures 1 and 2, each of the frames 30 has a long upper frame 31, a lower frame 32, and a pair of vertical frames 33. The frame 30 is formed in a roughly U-shaped cross section that opens toward the inner circumference.

図5Aは、網戸4を見付方向内側に移動させている途中の図である。一方の縦枠23は省略して示している。図5Aに示すように、外網戸420を引き違い窓100の見付方向内側へ引いていくと、図5Bに示すように、外網戸420の見付方向外側の網戸縦框43に固定された第2係合部4522が、内網戸410の見付方向内側の網戸縦框43に固定された第1係合部4512に係合する。外網戸420を移動させることによって、外網戸420及び内網戸410が係合した状態で、互いに連動して見付方向内側に移動する。反対方向に移動させる場合、第1係合部4512と第2係合部4522が係合している状態で内網戸410の見付方向内側の網戸縦框43を押せば、内網戸410に連動して外網戸420が見付方向外側に移動する。 Figure 5A shows the screen door 4 in the middle of being moved inward in the front view. One of the vertical frames 23 is omitted. As shown in Figure 5A, when the outer screen door 420 is pulled inward in the front view of the sliding window 100, the second engagement portion 4522 fixed to the screen door vertical frame 43 on the outer side in the front view of the outer screen door 420 engages with the first engagement portion 4512 fixed to the screen door vertical frame 43 on the inner side in the front view of the inner screen door 410, as shown in Figure 5B. By moving the outer screen door 420, the outer screen door 420 and the inner screen door 410 move inward in the front view in conjunction with each other while remaining engaged. To move in the opposite direction, if the first engaging portion 4512 and the second engaging portion 4522 are engaged and the vertical screen frame 43 on the inside of the inner screen 410 in the viewing direction is pushed, the outer screen 420 will move outward in the viewing direction in conjunction with the inner screen 410.

接続部6は、内網戸410と外障子330とを分離可能に接続し、内網戸410及び外障子330を互いに連動して開閉可能に構成する構成部である。接続部6は、網戸側障子接続部61と、磁石部材62と、を有する。 The connection part 6 is a component that separably connects the inner screen 410 and the outer screen 330, and configures the inner screen 410 and the outer screen 330 to be able to open and close in conjunction with each other. The connection part 6 has a screen side screen connection part 61 and a magnet member 62.

図3A及び図5Bに示すように、網戸側障子接続部61は、内網戸410に設けられる網戸係合部45の第1網戸係合部451と一体に形成される部材である。網戸側障子接続部61は、第1網戸係合部451の見込片4513における室内側の端部から屈曲し、見付方向に延びる面である。網戸側障子接続部61は、磁石固定部611と、網戸縦框固定部612と、を有する。磁石固定部611は、見込片4513における室内側の端部に繋がり、見付方向に延びる平坦な面である。磁石固定部611には、後述する障子3の縦框33に付着するための磁石部材62が固定される。網戸縦框固定部612は、網戸側障子接続部61を内網戸410の網戸縦框43に固定する面である。網戸縦框固定部612は、内網戸410の見付方向内側の網戸縦框43にねじにより固定される。網戸縦框固定部612が網戸縦框43に固定されることにより、網戸側障子接続部61と一体に連続している第1網戸係合部451がともに網戸縦框43に固定される。 3A and 5B, the screen door side shoji connection part 61 is a member formed integrally with the first screen door engagement part 451 of the screen door engagement part 45 provided on the inner screen door 410. The screen door side shoji connection part 61 is a surface that bends from the indoor side end of the projection piece 4513 of the first screen door engagement part 451 and extends in the visible direction. The screen door side shoji connection part 61 has a magnet fixing part 611 and a screen door vertical frame fixing part 612. The magnet fixing part 611 is a flat surface that is connected to the indoor side end of the projection piece 4513 and extends in the visible direction. A magnet member 62 for attaching to the vertical frame 33 of the shoji door 3 described later is fixed to the magnet fixing part 611. The screen door vertical frame fixing part 612 is a surface that fixes the screen door side shoji connection part 61 to the screen door vertical frame 43 of the inner screen door 410. The screen door vertical frame fixing part 612 is fixed with a screw to the screen door vertical frame 43 on the inside of the inner screen door 410 in the viewing direction. By fixing the screen door vertical frame fixing part 612 to the screen door vertical frame 43, the first screen door engagement part 451, which is integrally connected to the screen door side shoji connection part 61, is also fixed to the screen door vertical frame 43.

磁石部材62は、内網戸410及び外障子330を接続する。磁石部材62は、磁石62aと、保持プレート62bと、障子側磁石部63と、を有する。磁石62aは、板状の磁石である。保持プレート62bは、磁石62aを保持するプレートである。保持プレート62bを磁石固定部611にねじ留めすることにより、磁石62aが磁石固定部611に取り付けられ、網戸縦框43の室内側面に、磁力を有する部分が形成される。 The magnet member 62 connects the inner screen 410 and the outer screen 330. The magnet member 62 has a magnet 62a, a holding plate 62b, and a screen-side magnet part 63. The magnet 62a is a plate-shaped magnet. The holding plate 62b is a plate that holds the magnet 62a. By screwing the holding plate 62b to the magnet fixing part 611, the magnet 62a is attached to the magnet fixing part 611, and a part having magnetic force is formed on the indoor side of the screen vertical frame 43.

障子側磁石部63は、図3Aに示すように、外障子330における見付方向内側の縦框33に固定される。障子側磁石部63は、縦框33の室外側面に固定される板状の磁石であり、縦框33の室外側面から見込面33aを覆うように断面視略L字型に屈曲している。障子側磁石部63は、鉄や着磁性のステンレス等により構成されてもよい。障子側磁石部63は、網戸側障子接続部61の磁石固定部611と対向する位置に配置される。磁石固定部611には磁石部材62が取り付けられている。このため、図6に示すように、内網戸410が外障子330に重ねられると、磁石部材62の磁石62a及び障子側磁石部63が磁力により引き合って付着し、内網戸410と外障子330が接続される。 As shown in FIG. 3A, the screen side magnet part 63 is fixed to the vertical frame 33 on the inside of the outer screen 330 in the view direction. The screen side magnet part 63 is a plate-shaped magnet fixed to the exterior side surface of the vertical frame 33, and is bent in a roughly L-shape in cross section so as to cover the exterior side surface of the vertical frame 33 and the view surface 33a. The screen side magnet part 63 may be made of iron or magnetizable stainless steel. The screen side magnet part 63 is positioned opposite the magnet fixing part 611 of the screen side screen connection part 61. A magnet member 62 is attached to the magnet fixing part 611. Therefore, as shown in FIG. 6, when the inner screen 410 is placed on the outer screen 330, the magnet 62a of the magnet member 62 and the screen side magnet part 63 attract each other by magnetic force and adhere to each other, and the inner screen 410 and the outer screen 330 are connected.

図6に示すように、外障子330を中障子320に重ねるように見付方向内側へ引くと、内網戸410が外障子330に接続されているので、接続部6により接続された状態で内網戸410が外障子330と連動して移動する。内網戸410は外障子330の外側を覆うように配置されている。このため内網戸410が見付方向に移動するときに、外網戸420の見付方向内側の網戸縦框43に取り付けられたモヘア46が内網戸410の網部44に当接した状態でスライド移動する。 As shown in FIG. 6, when the outer screen 330 is pulled inward in the front view so that it overlaps with the middle screen 320, the inner screen 410, which is connected to the outer screen 330, moves in conjunction with the outer screen 330 while connected by the connection part 6. The inner screen 410 is arranged to cover the outside of the outer screen 330. Therefore, when the inner screen 410 moves in the front view, the mohair 46 attached to the screen vertical frame 43 on the inside of the outer screen 420 in the front view slides in contact with the mesh part 44 of the inner screen 410.

第1実施形態によれば、以下の効果が奏される。サッシ構造1を、複数の障子3と、複数の障子3の室外側に配置される複数の網戸4と、複数の網戸4のうち室内側の内網戸410と、複数の障子3のうち室外側の外障子330とを接続・分離可能な接続部6と、を含んで構成し、内網戸410と、外障子330とを、接続部6により接続された状態で連動して移動可能に構成した。内網戸410と外障子330が接続部6により接続されており、連動して移動する。このため、一度の動作で網戸4と障子3とを移動させることができ、利便性が向上する。さらに、障子3及び網戸4を開閉すると、障子3の縦框33と網戸4の網戸縦框43との位置がずれ、縦框33、網戸縦框43が目立つ場合がある。しかし、内網戸410と外障子330が接続されるため、内網戸410と外障子330とを重ねた状態で連動して移動させることができる。これにより、室内側から引き違い窓100を見た際に、障子3の縦框33に加えて網戸4の網戸縦框43がガラス351越しに視認されて意匠性に影響を与える度合いを低減することができる。 According to the first embodiment, the following effects are achieved. The sash structure 1 includes a plurality of screens 3, a plurality of screens 4 arranged on the exterior side of the plurality of screens 3, and a connection part 6 that can connect and separate the inner screen 410 on the interior side of the plurality of screens 4 and the outer screen 330 on the exterior side of the plurality of screens 3, and the inner screen 410 and the outer screen 330 are configured to be movable in conjunction with each other while connected by the connection part 6. The inner screen 410 and the outer screen 330 are connected by the connection part 6 and move in conjunction with each other. Therefore, the screen 4 and the screen 3 can be moved with a single operation, improving convenience. Furthermore, when the screen 3 and the screen 4 are opened or closed, the position of the vertical frame 33 of the screen 3 and the vertical frame 43 of the screen 4 may be misaligned, and the vertical frame 33 and the vertical frame 43 of the screen may be noticeable. However, because the inner screen 410 and the outer screen 330 are connected, the inner screen 410 and the outer screen 330 can be moved together while overlapping. This reduces the degree to which the screen 4's vertical frame 43 is visible through the glass 351 in addition to the vertical frame 33 of the screen 3 when looking at the sliding window 100 from inside the room, thereby affecting the design.

第1実施形態によれば、接続部6を、内網戸410及び外障子330を接続する磁石部材62を含んで構成した。内網戸410と外障子330が磁石部材62により接続されるため、内網戸410と外障子330を接続するためのスペースを小さくすることができる。さらに、内網戸410と外障子330を離す場合にも、使用者が力を入れるのみで済むため、開閉及び移動操作が単純で操作性が向上する。 According to the first embodiment, the connection portion 6 is configured to include a magnet member 62 that connects the inner screen door 410 and the outer screen 330. Because the inner screen door 410 and the outer screen 330 are connected by the magnet member 62, the space required to connect the inner screen door 410 and the outer screen 330 can be reduced. Furthermore, when separating the inner screen door 410 and the outer screen 330, the user only needs to apply force, simplifying the opening/closing and moving operations and improving operability.

本開示は上記実施形態に限定されるものではなく、本開示の目的を達成できる範囲での変形、改良等は本開示に含まれる。以降の説明において、第1実施形態と共通する構成については説明を省略し、共通する符号を用いる。 This disclosure is not limited to the above embodiment, and includes modifications, improvements, etc., within the scope that can achieve the purpose of this disclosure. In the following explanation, explanations of configurations common to the first embodiment will be omitted, and common reference numerals will be used.

図7A及び図7Bに示す第1実施形態の第1変形例に係る引き違い窓100Aでは、第1網戸係合部451Aは、第2網戸係合部452と同一の形状をしている。すなわち、図4に示す第2網戸係合部452の部材を上下逆さまにすることで、図4に示す室内側面4521を、室外側面4511Aとして内網戸410の網戸縦框43の室外側面にねじにて固定することができる。同様に、断面視略L字型の第2係合部4522が、第1係合部4512Aを構成する。 In the sliding window 100A according to the first modified example of the first embodiment shown in Figures 7A and 7B, the first screen engagement portion 451A has the same shape as the second screen engagement portion 452. That is, by turning the member of the second screen engagement portion 452 shown in Figure 4 upside down, the indoor side surface 4521 shown in Figure 4 can be fixed to the outdoor side surface of the screen vertical frame 43 of the inner screen 410 with a screw as the outdoor side surface 4511A. Similarly, the second engagement portion 4522, which is generally L-shaped in cross section, constitutes the first engagement portion 4512A.

引き違い窓100Aは、第1実施形態と比べて、網戸側障子接続部61を有していない。磁石部材62Aは、平板状の磁石62aと、磁石62aを保持する横断面視略コの字状の保持プレート62bと、障子側磁石部63Aと、を、有する。内網戸410の網戸縦框43の室外側延出片402bに、直接、磁石部材62Aの磁石62aが固定されている。図7Bに示すように、保持プレート62bは、内網戸410の網戸縦框43における室内側延出片402aと室外側延出片402bとの間に配置されている。保持プレート62bは、上下方向の長さが磁石62aよりも長く、上下方向の中央部に磁石62aが保持プレート62bに係合するように取り付けられる。網戸縦框43の室内側の面の一部に貫通孔43aが形成されている。保持プレート62bの一部が貫通孔43aを挿通する。磁石62aは、保持プレート62bよりも室内側へ見込方向に突出しており、貫通孔43aから室内側に突出する。保持プレート62bを網戸縦框43の室内側面にねじ留めすることにより、網戸縦框43の室内側面に、磁力を有する部分が形成される。磁石62aは、外障子330の縦框33の室外側面に取り付けられた障子側磁石部63Aに磁力により付着する。 The sliding window 100A does not have a screen door side shoji connection part 61, unlike the first embodiment. The magnet member 62A has a flat magnet 62a, a holding plate 62b that is roughly U-shaped in cross section to hold the magnet 62a, and a shoji side magnet part 63A. The magnet 62a of the magnet member 62A is fixed directly to the outdoor extension piece 402b of the screen door vertical frame 43 of the inner screen door 410. As shown in FIG. 7B, the holding plate 62b is disposed between the indoor extension piece 402a and the outdoor extension piece 402b of the screen door vertical frame 43 of the inner screen door 410. The holding plate 62b is longer in the vertical direction than the magnet 62a, and is attached so that the magnet 62a engages with the holding plate 62b in the vertical center. A through hole 43a is formed in a part of the indoor side surface of the screen door vertical frame 43. A part of the retaining plate 62b is inserted through the through hole 43a. The magnet 62a protrudes in the forward direction toward the interior side of the room beyond the retaining plate 62b, and protrudes from the through hole 43a toward the interior side of the room. By screwing the retaining plate 62b to the interior side of the screen frame 43, a part having magnetic force is formed on the interior side of the screen frame 43. The magnet 62a is attached by magnetic force to the screen side magnet part 63A attached to the exterior side of the frame 33 of the outer screen 330.

障子側磁石部63Aは、第1実施形態と比べて、縦框33の見込面33aを覆う部分を有さない。障子側磁石部63Aは、略長方形のプレートであり、外障子330における見付方向内側の縦框33の室外側面に固定されている。 Compared to the first embodiment, the screen side magnet part 63A does not have a portion that covers the visible surface 33a of the vertical frame 33. The screen side magnet part 63A is a roughly rectangular plate, and is fixed to the exterior surface of the vertical frame 33 on the inside of the visible direction of the outer screen 330.

第1変形例によれば、第1網戸係合部451Aと第2網戸係合部452の部材を共通化できるため、部品点数を低減させることができる。 According to the first modified example, the first screen door engaging portion 451A and the second screen door engaging portion 452 can be made of the same material, thereby reducing the number of parts.

図8A及び図8Bに示す第1実施形態の第2変形例に係る引き違い窓100Bでは、磁石部材62Bは、外障子330の縦框33の室外側面に取り付けられている。引き違い窓100Bは、第1実施形態と比べて、障子側磁石部63を有していない。図8Bに示すように、磁石部材62Bは、磁石62aと、保持プレート62bと、を有する。保持プレート62bは、断面視略L字型の形状を有し、縦框33の室外側の見付面に沿う室外側面当接部621と、縦框33の見込面に沿う見込面当接部622と、を有する。保持プレート62bは、樹脂により形成され、室外側面当接部621に磁石62aを保持するように構成される。 In the sliding window 100B according to the second modified example of the first embodiment shown in Fig. 8A and Fig. 8B, the magnet member 62B is attached to the exterior side of the vertical frame 33 of the outer screen 330. Unlike the first embodiment, the sliding window 100B does not have a screen-side magnet part 63. As shown in Fig. 8B, the magnet member 62B has a magnet 62a and a holding plate 62b. The holding plate 62b has a generally L-shaped cross section and has an exterior side abutment part 621 that fits along the exterior-side visible surface of the vertical frame 33, and a projected surface abutment part 622 that fits along the projected surface of the vertical frame 33. The holding plate 62b is made of resin and is configured to hold the magnet 62a to the exterior side abutment part 621.

第2変形例では、図8Aに示すように、網戸係合部45の第1網戸係合部451Bと網戸側障子接続部61Bが一体に成形されている。網戸側障子接続部61Bは、着磁性の素材、例えば、鉄や着磁性のステンレスで構成され、磁石部材62Bの一部を構成する。網戸側障子接続部61Bは、第1網戸係合部451の見込片4513における室内側の端部から屈曲し、見付方向に延びる。網戸側障子接続部61Bが直接磁石62aに付着することで、内網戸410と外障子330が接続される。 In the second modified example, as shown in FIG. 8A, the first screen door engagement portion 451B of the screen door engagement portion 45 and the screen door side screen connection portion 61B are integrally molded. The screen door side screen connection portion 61B is made of a magnetic material, such as iron or magnetic stainless steel, and constitutes part of the magnet member 62B. The screen door side screen connection portion 61B bends from the indoor end of the projection piece 4513 of the first screen door engagement portion 451 and extends in the visible direction. The screen door side screen connection portion 61B is directly attached to the magnet 62a, connecting the inner screen door 410 and the outer screen door 330.

第2変形例によれば、第1網戸係合部451と網戸側障子接続部61Bとを一体の部材で構成することができる。そして、磁石部材62Bを外障子330の縦框33側に取り付けることで、網戸4の構成を簡易にし、軽量化が可能になる。 According to the second modified example, the first screen door engagement portion 451 and the screen door side shoji connection portion 61B can be constructed as a single member. In addition, by attaching the magnet member 62B to the vertical frame 33 side of the outer shoji door 330, the structure of the screen door 4 can be simplified and made lighter.

図9A及び図9Bに示す第2実施形態に係る引き違い窓100Cでは、接続部6Cは、磁石部材62Cと、当接部64と、を有する。引き違い窓100Cは、第1実施形態と比べて、網戸側障子接続部61を有していない。 In the sliding window 100C according to the second embodiment shown in Figures 9A and 9B, the connection portion 6C has a magnet member 62C and an abutment portion 64. Unlike the first embodiment, the sliding window 100C does not have a screen door side shoji connection portion 61.

第1網戸係合部451Cは、見込片4513から見付方向内側に突出する見付片4514を有する。見付片4514は、網戸4の網戸縦框43における室内側延出片402aに当接するとともに室内側延出片402aと平行に延びる。見付片4514は、室内側延出片402aにねじにて固定される。 The first screen engagement portion 451C has a sight piece 4514 that protrudes inward in the sight direction from the sight piece 4513. The sight piece 4514 abuts against the indoor side extension piece 402a of the screen vertical frame 43 of the screen 4 and extends parallel to the indoor side extension piece 402a. The sight piece 4514 is fixed to the indoor side extension piece 402a with a screw.

磁石部材62Cは、磁石62aと、保持プレート62bとを有する。保持プレート62bは、外障子330における縦框33の見込面33aに固定される。 The magnet member 62C has a magnet 62a and a retaining plate 62b. The retaining plate 62b is fixed to the projecting surface 33a of the vertical frame 33 of the outer screen 330.

当接部64は、内網戸410の見付方向の端部側から延び、外障子330の見付方向の端部に向けて延びる。当接部64は、第1網戸係合部451Cの見込片4513から連続して、第1網戸係合部451Cと一体に形成される。当接部64は、着磁性部材配置代641と、障子当接部642と、を有する。着磁性部材配置代641は、第1網戸係合部451Cの室内側の端部から、見付方向内側へわずかに屈曲する。障子当接部642は、着磁性部材配置代641の見付方向内側の端部から略直角に屈曲して見込方向に延びる。障子当接部642は、外障子330における縦框33の見込面33aに対向して延びる。縦框33の見込面33aに対向する障子当接部642の内面には、磁石643が固定される。磁石643は、着磁性の素材で形成される長方形のプレートである。磁石643の厚さは、着磁性部材配置代641の見付方向に延びる長さ寸法よりも小さい。磁石643は、磁石62aと対向する位置に取り付けられる。 The abutment portion 64 extends from the end side of the inner screen 410 in the visible direction and extends toward the end of the outer screen 330 in the visible direction. The abutment portion 64 is continuous with the projection piece 4513 of the first screen engagement portion 451C and is formed integrally with the first screen engagement portion 451C. The abutment portion 64 has a magnetic member arrangement portion 641 and a screen abutment portion 642. The magnetic member arrangement portion 641 is slightly bent inward in the visible direction from the end on the indoor side of the first screen engagement portion 451C. The screen abutment portion 642 is bent at approximately a right angle from the end on the inner side in the visible direction of the magnetic member arrangement portion 641 and extends in the visible direction. The screen abutment portion 642 extends opposite the projection surface 33a of the vertical frame 33 in the outer screen 330. A magnet 643 is fixed to the inner surface of the door abutment portion 642 that faces the visible surface 33a of the vertical frame 33. The magnet 643 is a rectangular plate made of a magnetizable material. The thickness of the magnet 643 is smaller than the length of the magnetizable member placement area 641 extending in the visible direction. The magnet 643 is attached in a position opposite the magnet 62a.

図9Aに示すように、当接部64は、第1網戸係合部451Cと連続している。当接部64には、磁石643が設けられており、外障子330の縦框33における見込面33aに配置された磁石62aに付着している。当接部64が外障子330の縦框33の見付方向の端部に磁石643を介して当接する。同時に、第1網戸係合部451Cの見込片4513が内網戸410の網戸縦框43における一対の延出片402に当接する。この状態で、外障子330を見付方向の外側に向かって押せば、外障子330が移動するに伴って、磁石643により磁石部材62Cに磁着している当接部64が外障子330に連動して移動する。当接部64の移動に伴って、当接部64と一体に形成された見込片4513に押される内網戸410が移動する。 9A, the abutment portion 64 is continuous with the first screen door engagement portion 451C. A magnet 643 is provided on the abutment portion 64, and is attached to a magnet 62a arranged on the projection surface 33a of the vertical frame 33 of the outer screen 330. The abutment portion 64 abuts against the end of the vertical frame 33 of the outer screen 330 in the projection direction via the magnet 643. At the same time, the projection piece 4513 of the first screen door engagement portion 451C abuts against a pair of extension pieces 402 on the vertical frame 43 of the inner screen 410. In this state, if the outer screen 330 is pushed outward in the projection direction, as the outer screen 330 moves, the abutment portion 64, which is magnetically attached to the magnet member 62C by the magnet 643, moves in conjunction with the outer screen 330. As the abutment portion 64 moves, the inner screen door 410 moves as it is pushed by the projection piece 4513 formed integrally with the abutment portion 64.

逆に、外障子330を見付方向内側に向かって押すと、外障子330の縦框33の見込面33aが、当接部64を見付方向内側に押すので、外障子330と内網戸410とが連動して移動する。 Conversely, when the outer screen 330 is pushed inward in the facing direction, the projecting surface 33a of the vertical frame 33 of the outer screen 330 pushes the abutment portion 64 inward in the facing direction, so that the outer screen 330 and the inner screen 410 move in conjunction with each other.

第2実施形態によれば、第1網戸係合部451Cと当接部64とが一体に形成され、当接部64が外障子330の見付方向の端部に当接可能なので、外障子330を見付方向の内側へ移動させる際は、外障子330と内網戸410との連動を物理的に一体の部材を押すことで行うことができる。したがって、より確実で安定した移動が可能となる。外障子330を見付方向外側へ移動させる際に、外障子330と内網戸410との連動を磁石で行うように構成することで、接続部6Cの構成や配置を複雑にせず、製造コストを低減するとともに施工性を向上させることができる。 According to the second embodiment, the first screen engagement portion 451C and the abutment portion 64 are formed integrally, and the abutment portion 64 can abut against the end of the outer screen 330 in the front direction. Therefore, when moving the outer screen 330 inward in the front direction, the outer screen 330 and the inner screen 410 can be linked by pushing the physically integrated member. This allows for more reliable and stable movement. By configuring the outer screen 330 to link with the inner screen 410 using a magnet when moving the outer screen 330 outward in the front direction, it is possible to reduce manufacturing costs and improve workability without complicating the configuration and arrangement of the connection portion 6C.

The projection outer portion 6511d is located opposite the abutment surface 6511a and is a side portion that connects the exterior side surface 6511b and the interior side surface 6511c. The projection outer portion 6511d extends from the exterior side surface 6511b toward the interior side in the projection direction, bends in the projection direction near the center of the projection direction, moves away from the abutment surface 6511a, and then extends to the end of the interior side surface 6511c in the projection direction. The engagement claw 6511e is formed on the projection outer portion 6511d and is a cantilever-shaped portion that can be elastically deformed. The tip of the engagement claw 6511e bulges out from the base end side so that it can engage with the protruding engagement portion 653 described later.

貫通孔配置部6512は、ねじを挿通可能な貫通孔6512aが形成された略半円形の部分であり、固定部本体部6511の上端と下端からそれぞれ延びている。 The through-hole arrangement portion 6512 is a substantially semicircular portion in which a through-hole 6512a through which a screw can be inserted is formed, and extends from both the upper and lower ends of the fixing portion main body portion 6511.

突出係合部653は、固定部本体部6511に係合して室外側及び室内側へ進退可能な可動部品である。突出係合部653は、突出本体部6531と、係合爪6532と、を有する。突出本体部6531は、ストッパ固定部651の見込外側部6511dの屈曲形状に沿って屈曲し、見込外側部6511dの外側面に係合している。突出本体部6531は、見込外側部6511dに係合し、室内外方向にスライド可能に配置されている。突出本体部6531の室外側の先端は、図10Aに示すように、後述する被係合部66に係合可能に配置されているとともに、内網戸410の網戸縦框43における室内側延出片402aの端部に係合可能に配置されている。突出本体部6531の室内側は、見込外側部6511dの室内側の部分の側面に当接している。係合爪6532は、突出本体部6531における固定部本体部6511側に、ストッパ固定部651の係合爪6511eに係合可能に配置されている。係合爪6532は、突出本体部6531における見込方向の中央部付近に、室外側から室内側に向かって片持ち状に延び、先端側が基端側よりも膨出している。 The protruding engagement part 653 is a movable part that can engage with the fixing part main body part 6511 and move forward and backward to the outside and inside of the room. The protruding engagement part 653 has a protruding main body part 6531 and an engagement claw 6532. The protruding main body part 6531 is bent along the bent shape of the projected outer part 6511d of the stopper fixing part 651 and engages with the outer surface of the projected outer part 6511d. The protruding main body part 6531 engages with the projected outer part 6511d and is arranged so as to be slidable in the indoor and outdoor directions. As shown in FIG. 10A, the tip of the protruding main body part 6531 on the outdoor side is arranged so as to be able to engage with the engaged part 66 described later, and is arranged so as to be able to engage with the end of the indoor extension piece 402a of the screen vertical frame 43 of the inner screen 410. The indoor side of the protruding main body part 6531 abuts against the side of the indoor side part of the projected outer part 6511d. The engagement claw 6532 is arranged on the fixing part main body 6511 side of the protruding main body 6531 so as to be able to engage with the engagement claw 6511e of the stopper fixing part 651. The engagement claw 6532 extends in a cantilever shape from the outside to the inside of the room near the center of the protruding main body 6531 in the projection direction, with the tip side bulging out more than the base end side.

付勢部652は、固定部本体部6511の内部に配置されるコイルばねである。付勢部652は、突出係合部653を常に室外側へ付勢するように突出係合部653に当接している。 The biasing portion 652 is a coil spring disposed inside the fixing portion main body 6511. The biasing portion 652 abuts against the protruding engagement portion 653 so as to constantly bias the protruding engagement portion 653 toward the outside of the room.

被係合部66は、図10Aに示すように、内網戸410の見付方向内側の網戸縦框43に固定される。被係合部66は、図10Aに示すように、2つの断面視略L字型の部分が接続されたような形状をしている。被係合部66は、網戸固定部661と、ストッパ係合部662と、を有する。網戸固定部661は、固定面661aと、見込面661bとを有する。固定面661aは、内網戸410の網戸縦框43における室外側延出片402bの室内側の面にビスにて固定される。見込面661bは、固定面661aから略直角に屈曲して見込方向へ延びる面である。ストッパ係合部662は、係合見付面662aと、係合見込面662bと、を有する。係合見付面662aは、網戸固定部661の見込面661bにおける室内側の端部から略直角に屈曲して見付方向に延びる面である。係合見付面662aは、ストッパ部材65の突出係合部653に当接する面である。詳細には、突出係合部653の突出本体部6531の室外側の端部が、係合見付面662aの室内側の面に当接する。係合見込面662bは、突出本体部6531の室外側の端部から見込方向に延びる端部に対向する。係合見付面662aと係合見込面662bが突出本体部6531の室外側の端部を覆うように配置され、係合見付面662a及び係合見込面662bにより構成される角に突出本体部6531が係合することで、ストッパ部材65が被係合部66に係合する。 As shown in FIG. 10A, the engaged portion 66 is fixed to the screen frame 43 on the inner side of the inner screen 410 in the projection direction. As shown in FIG. 10A, the engaged portion 66 has a shape in which two parts that are approximately L-shaped in cross section are connected. The engaged portion 66 has a screen fixing portion 661 and a stopper engaging portion 662. The screen fixing portion 661 has a fixing surface 661a and a projection surface 661b. The fixing surface 661a is fixed to the indoor surface of the outdoor extension piece 402b in the screen frame 43 of the inner screen 410 with a screw. The projection surface 661b is a surface that bends at an approximately right angle from the fixing surface 661a and extends in the projection direction. The stopper engaging portion 662 has an engagement projection surface 662a and an engagement projection surface 662b. The engagement surface 662a is a surface that bends at a right angle from the indoor end of the projection surface 661b of the screen fixing portion 661 and extends in the projection direction. The engagement surface 662a is a surface that abuts against the protruding engagement portion 653 of the stopper member 65. In detail, the outdoor end of the protruding main body portion 6531 of the protruding engagement portion 653 abuts against the indoor surface of the engagement surface 662a. The engagement surface 662b faces the end that extends in the projection direction from the outdoor end of the protruding main body portion 6531. The engagement surface 662a and the engagement surface 662b are arranged to cover the outdoor end of the protruding main body portion 6531, and the protruding main body portion 6531 engages with the corner formed by the engagement surface 662a and the engagement surface 662b, so that the stopper member 65 engages with the engaged portion 66.

ストッパ部材65は、常に付勢部652により付勢されているので、ストッパ部材65の突出係合部653が被係合部66のストッパ係合部662と、網戸縦框43の室内側延出片402aとの間に挿入されて係合している。これにより、内網戸410と外障子330とが接続されている。外障子330の見付方向の端部を見付方向の外側に向かって押せば、突出係合部653の先端側が網戸縦框43の室内側延出片402aを同時に押すので、外障子330と内網戸410とが連動して動き、移動する。逆に、外障子330を見付方向内側に向かって押すと、突出係合部653の先端側がストッパ係合部662の係合見込面662bを押すので、外障子330と内網戸410とが連動して動き、移動する。 The stopper member 65 is always biased by the biasing portion 652, so that the protruding engagement portion 653 of the stopper member 65 is inserted between the stopper engagement portion 662 of the engaged portion 66 and the indoor extension piece 402a of the screen vertical frame 43 and engaged. This connects the inner screen 410 and the outer screen 330. If the end of the outer screen 330 in the front direction is pushed toward the outside in the front direction, the tip side of the protruding engagement portion 653 simultaneously pushes the indoor extension piece 402a of the screen vertical frame 43, so that the outer screen 330 and the inner screen 410 move and move in conjunction with each other. Conversely, if the outer screen 330 is pushed toward the inside in the front direction, the tip side of the protruding engagement portion 653 pushes the engagement projection surface 662b of the stopper engagement portion 662, so that the outer screen 330 and the inner screen 410 move and move in conjunction with each other.

外障子330と内網戸410の動きを連動させたくない場合、ストッパ部材65の被係合部66に対する係合を解くことができる。具体的には、突出係合部653に使用者が手を掛けて室内側へ引き寄せると、付勢部652が縮まる。このとき、図10Bに示すように、突出本体部6531側に設けられている係合爪6532が、ストッパ固定部651の見込外側部6511dに設けられた係合爪6511eに弾性変形して係合する。突出本体部6531の係合爪6532とストッパ固定部651の係合爪6511eが係合すると、突出本体部6531が室内側に引き寄せられた状態で固定されるので、外障子330と内網戸410の係合が解かれる。よって、外障子330と内網戸410は別々に移動することができる。 If you do not want the outer screen 330 and the inner screen 410 to move in tandem, you can release the engagement of the stopper member 65 with the engaged portion 66. Specifically, when the user places his or her hand on the protruding engagement portion 653 and pulls it toward the inside of the room, the biasing portion 652 contracts. At this time, as shown in FIG. 10B, the engagement claw 6532 provided on the protruding main body portion 6531 side elastically deforms and engages with the engagement claw 6511e provided on the projected outer portion 6511d of the stopper fixing portion 651. When the engagement claw 6532 of the protruding main body portion 6531 and the engagement claw 6511e of the stopper fixing portion 651 engage, the protruding main body portion 6531 is fixed in a state pulled toward the inside of the room, and the engagement between the outer screen 330 and the inner screen 410 is released. Therefore, the outer screen 330 and the inner screen 410 can move separately.

第3実施形態では、網戸係合部45の第1網戸係合部451Dは、内網戸410の網戸縦框43における室外側の面に固定されている。第1網戸係合部451Dの形状は、図4に示す第2網戸係合部452の形状と同一である。第1網戸係合部451Dは、網戸縦框43における被係合部66が固定されていない部分に固定されている。第2網戸係合部452Dの配置は、第1実施形態の場合と同様である。すなわち、第2網戸係合部452Dは、外網戸420の見付方向外側の網戸縦框43における室内側の面に、第1網戸係合部451Dと係合可能な位置に固定されている。したがって、第3実施形態においても、内網戸410と外網戸420は連動して移動することができる。 In the third embodiment, the first screen door engaging portion 451D of the screen door engaging portion 45 is fixed to the exterior side surface of the screen door vertical frame 43 of the inner screen door 410. The shape of the first screen door engaging portion 451D is the same as the shape of the second screen door engaging portion 452 shown in FIG. 4. The first screen door engaging portion 451D is fixed to a portion of the screen door vertical frame 43 where the engaged portion 66 is not fixed. The arrangement of the second screen door engaging portion 452D is the same as in the first embodiment. That is, the second screen door engaging portion 452D is fixed to a position where it can engage with the first screen door engaging portion 451D on the interior side surface of the screen door vertical frame 43 on the outer side of the viewing direction of the outer screen door 420. Therefore, even in the third embodiment, the inner screen door 410 and the outer screen door 420 can move in conjunction with each other.

第3実施形態によれば、ストッパ部材65と被係合部66の機械的な係合によって、外障子330と内網戸410の動きを連動させることができるので、障子や網戸4が大型化により重量が増加しても、より確実に外障子330と内網戸410の移動を連動させることができる。 According to the third embodiment, the movement of the outer screen 330 and the inner screen 410 can be linked by the mechanical engagement of the stopper member 65 and the engaged portion 66, so that even if the screen or screen 4 is enlarged and therefore heavy, the movement of the outer screen 330 and the inner screen 410 can be linked more reliably.

第1実施形態では、網戸係合部45が網戸縦框43の上下方向の一方と他方に取り付ける丈の短い部品として説明した。しかし、配置する場所は上下方向の一方と他方に限定されない。例えば上下方向の中央部に一か所配置してもよい。さらに、網戸係合部は、網戸縦框43の上下方向の一方から他方に亘って配置される長尺状の形状を有していてもよい。網戸係合部が上下方向に通しで配置されることで、外網戸420側と内網戸410側の配置を厳密に合わせる必要がなくなり、施工性及び操作性が向上する。 In the first embodiment, the screen door engaging portion 45 is described as a short part that is attached to one side and the other side of the vertical screen door frame 43 in the vertical direction. However, the location of placement is not limited to one side and the other side in the vertical direction. For example, it may be placed in one place in the vertical center. Furthermore, the screen door engaging portion may have a long shape that is placed from one side to the other side in the vertical direction of the screen door frame 43. By placing the screen door engaging portion continuously in the vertical direction, it is no longer necessary to strictly match the placement of the outer screen door 420 side and the inner screen door 410 side, improving workability and operability.

第1実施形態~第3実施形態では、モヘア46は外網戸420に取り付けられ、内網戸410に向かって見込方向に延びている。しかし、内網戸410に取り付けられ、外網戸420に向かって見込方向に延びていてもよい。 In the first to third embodiments, the mohair 46 is attached to the outer screen 420 and extends in the forward direction toward the inner screen 410. However, it may also be attached to the inner screen 410 and extend in the forward direction toward the outer screen 420.

上記の実施形態では、障子3が6枚、網戸4が4枚設けられた引き違い窓100を例に説明した。障子3や網戸4の数は限定されない。例えば、障子3が3枚設けられた引き違い窓であってもよく、それより多くてもよい。 In the above embodiment, a sliding window 100 having six shoji screens 3 and four screen doors 4 has been described as an example. The number of shoji screens 3 and screen doors 4 is not limited. For example, the sliding window may have three shoji screens 3, or more than that.
