Description

窓window
　本発明は、窓に関する。 The present invention relates to windows.
　昨今のコロナ禍において、室内の通風換気を定期的に行うことが重要となっているが、例えば、一戸建て住宅の１階で道路に面している部屋や、集合住宅の共用廊下に面している部屋では、窓のすぐ外側を人が通行することから、通行人の視線を気にして、窓を開放しての通風換気が疎かになりがちである。カーテンを引きまわしてから窓を開放することなどももちろんできるが、通行人の視線が気になることに変わりはなく、また、採光性などに影響が出る。 In the recent corona disaster, it is important to regularly ventilate the room. In the room where the room is, people pass by just outside the window, so they tend to neglect ventilation by opening the window because they are concerned about the eyes of passers-by. Of course, it is possible to open the windows after pulling the curtains, but this does not change the visibility of passers-by, and it also affects the lighting performance.
　一戸建て住宅、集合住宅をはじめ種々の建物においては、窓は、採光性、通風性、遮視性、防犯性、防虫性などの様々な機能性を考慮しながら、建物の置かれている環境、デザイン性、居住人又は利用者の意向により、様々なタイプが採用されている。例えば、引き違い窓、上げ下げ窓、開き窓、すべり出し窓、倒し窓、突き出し窓など、様々な窓のタイプが用意されている。これらのタイプの窓の中で、一般に多く用いられている引き違い窓に対し、遮視性に着目したものとして、建物の外壁よりも室外側に突出させて開放する平行突き出し窓が知られている（例えば、特許文献１参照）。 In various buildings such as detached houses and collective housing, the windows are designed to provide various functions such as lighting, ventilation, visibility, crime prevention, and insect repellency. Various types are adopted depending on the design and the intention of residents or users. For example, there are various types of windows such as sliding windows, double-hung windows, casement windows, sliding windows, tilting windows, and projecting windows. Among these types of windows, in contrast to the sliding windows that are commonly used, parallel projecting windows, which are opened by projecting from the outer wall of the building to the outside, are known as those that focus on visibility. (See Patent Document 1, for example).
特開２０１４－０４７５４３号公報JP 2014-047543 A
　しかしながら、平行突き出し窓は、引き違い窓などに対して外部からの視線を遮る遮視性が優れているが、窓の開放時に障子を建物の室外側に突出させるため、すぐその外側を通行する通行人の邪魔になったり、左右横の隙間から室内を視認されたりするなどの問題があった。 However, parallel projecting windows are excellent in blocking the line of sight from the outside compared to double sliding windows. There were problems such as being an obstacle for passers-by and being able to see the interior through gaps on the left and right sides.
　本発明は、上記のような事情に鑑みなされたものであり、通行人を含め建物の外部に存する者の視線を気にすることなく、また、通行人の邪魔にならずに通風換気を行える窓を提供することを目的とする。 The present invention has been made in view of the above circumstances, and can perform ventilation without worrying about the line of sight of people outside the building, including passers-by, and without disturbing passers-by.

A space surrounded by the peripheral edges of the upper frame 21, the lower frame 22, the right frame 23, and the left frame 24 forms an outdoor-side opening 29, and the space extending between the upper back frame 25 and the lower back frame 27 is an indoor-side opening. forming part 26; An air tight rubber 28 is provided around the room-side opening 26 . The shoji 30 is formed from an upper rail 31 , a lower rail 32 , a right frame 33 , a left frame 34 and glass (for example, multi-layer glass) 35 .
　窓１０は、建物Ｂに設けられるが（後述する図９から図１２参照）、図１及び図２に示すように、室外側開口部２９が室内側開口部２６よりも広く設定されており、室外側開口部２９が室内側開口部２６よりも広く設定されたことによって窓枠２０の内側において余剰空間部２１ａ，２２ａが形成される。障子３０は、室内側開口部２６と室外側開口部２９との間で室内側開口部２６を開閉する。後述するように、障子３０は、障子３０と窓枠２０との間に介設された移動機構４０によって、室外側開口部２９と室内側開口部２６との間で移動させられる。障子３０が窓枠２０の室内側開口部２６から室外側開口部２９に向かって移動して開放されたとき、余剰空間部２１ａ，２２ａは、建物Ｂの室内側と室外側を連通させる。 The window 10 is provided in the building B (see FIGS. 9 to 12 described later), but as shown in FIGS. 1 and 2, the outdoor opening 29 is set wider than the indoor opening 26, Excess spaces 21 a and 22 a are formed inside the window frame 20 by setting the outdoor-side opening 29 wider than the indoor-side opening 26 . The shoji 30 opens and closes the indoor opening 26 between the indoor opening 26 and the outdoor opening 29 . As will be described later, the shoji 30 is moved between the outdoor-side opening 29 and the indoor-side opening 26 by a moving mechanism 40 interposed between the shoji 30 and the window frame 20 . When the shoji 30 is moved from the indoor side opening 26 of the window frame 20 toward the outdoor side opening 29 and opened, the surplus space parts 21a and 22a communicate the indoor side and the outdoor side of the building B.例文帳に追加
　ここで、余剰空間部２１ａ，２２ａは、少なくとも１箇所において形成されていればよい。すなわち、図１及び図２では、余剰空間部２１ａ，２２ａについて、上枠２１内側の余剰空間部２１ａと下枠２２内側の余剰空間部２２ａの双方が形成されている態様を示しているが、後述するように、本発明の要旨は、双方が形成される態様に限られるものではなく、余剰空間部２１ａのみ、余剰空間部２２ａのみに形成されている態様も含むものである。すなわち、余剰空間部２１ａ，２２ａは、上枠２１内側及び／又は下枠２２内側に設けられていればよい。 Here, the redundant space portions 21a and 22a may be formed at least one location. That is, in FIGS. 1 and 2, regarding the surplus space portions 21a and 22a, both the surplus space portion 21a inside the upper frame 21 and the surplus space portion 22a inside the lower frame 22 are formed. As will be described later, the gist of the present invention is not limited to the aspect in which both are formed, but includes aspects in which only the surplus space 21a and only the surplus space 22a are formed. That is, the surplus spaces 21a and 22a may be provided inside the upper frame 21 and/or inside the lower frame 22 .
　窓枠２０は、室内外方向（前後方向）に所定の奥行をもって形成されており、窓枠２０の前面（室外側開口部２９）は、窓１０が設けられる建物Ｂの外壁の外面と実質的にほぼ同一面に位置するように配置される。障子３０は、窓枠２０の右枠２３、左枠２４に設けられている移動機構４０の障子ガイドレール４１に沿って、室内外方向（前後方向）に平行して移動可能であり（ここでは、スライド移動。図１及び図２中、実線白矢印参照）、障子３０は、窓枠２０の室外側で開放状態、窓枠２０の室内側で閉鎖状態となる。 The window frame 20 is formed with a predetermined depth in the indoor-outdoor direction (front-rear direction), and the front surface of the window frame 20 (outdoor opening 29) is substantially aligned with the outer surface of the outer wall of the building B where the window 10 is provided. are arranged so as to be positioned substantially flush with each other. The shoji 30 can move in parallel with the indoor and outdoor directions (front and back directions) along the shoji guide rails 41 of the movement mechanism 40 provided on the right frame 23 and the left frame 24 of the window frame 20 (here , slide movement (see solid white arrows in FIGS. 1 and 2), the shoji 30 is open on the outdoor side of the window frame 20 and closed on the indoor side of the window frame 20 .
　窓枠２０には、障子３０の上方（窓枠２０の上枠２１側内部）において、上枠２１、上背枠２５、上背枠２５に対応する位置の右枠２３及び左枠２４によって囲われた空間である余剰空間部２１ａが設けられている。同様に、障子３０の下方（窓枠２０の下枠２２側内部）において、下枠２２、下背枠２７、下背枠２７に対応する位置の右枠２３及び左枠２４によって囲われた空間である余剰空間部２２ａが設けられている。換言すると、余剰空間部２１ａ，２２ａは、障子３０が開閉に伴って移動するための空間とは別の空間を形成している。障子３０を室内側開口部２６から室外側開口部２９に向かって移動して開放したときには（図２参照）、余剰空間部２１ａ，２２ａと室内側開口部２６を介して、窓１０の室外側と室内側は連通し、通風換気が行われる。一方、障子３０を室内側に閉鎖したときには（図１参照）、窓枠２０の室内側開口部２６が障子３０によって塞がれ、窓１０の室外側と室内側は遮断される。 The window frame 20 is surrounded by an upper frame 21, an upper back frame 25, and a right frame 23 and a left frame 24 at positions corresponding to the upper back frame 25 above the shoji 30 (inside the upper frame 21 side of the window frame 20). A surplus space portion 21a, which is a closed space, is provided. Similarly, below the shoji 30 (inside the lower frame 22 side of the window frame 20), the lower frame 22, the lower back frame 27, the space surrounded by the right frame 23 and the left frame 24 at positions corresponding to the lower back frame 27 A surplus space portion 22a is provided. In other words, the surplus spaces 21a and 22a form a space separate from the space in which the shoji 30 moves as it opens and closes. When the shoji 30 is moved from the indoor side opening 26 toward the outdoor side opening 29 and opened (see FIG. 2), the outdoor side of the window 10 is opened through the redundant space portions 21a and 22a and the indoor side opening 26. and the indoor side communicate with each other, and ventilation is performed. On the other hand, when the shoji 30 is closed to the indoor side (see FIG. 1), the indoor-side opening 26 of the window frame 20 is closed by the shoji 30, and the outdoor side and the indoor side of the window 10 are blocked.
　以下に、窓１０のより詳しい構造について、図３から図７を参照して説明する。図３は窓枠２０の正面図を、図４は障子３０の背面図を、図５は窓１０の縦断面図を、図６は窓１０の横断面図を、図７は窓１０の室外側に配置された防犯機構５０（面格子）の正面図を、それぞれ示す。なお、本発明の要旨は図３から図７に示す態様に限定されるものではなく、種々の変形を加えることが可能である。 A more detailed structure of the window 10 will be described below with reference to FIGS. 3 to 7. FIG. 3 is a front view of the window frame 20, FIG. 4 is a rear view of the shoji 30, FIG. 5 is a vertical cross-sectional view of the window 10, FIG. The front view of the crime prevention mechanism 50 (surface grating) arrange|positioned outside is shown, respectively. The gist of the present invention is not limited to the aspects shown in FIGS. 3 to 7, and various modifications can be added.
　窓枠２０は、図３に示すように、正面視において、例えば、縦横比で縦長の矩形に形成されている。窓枠２０の正面視の形状は、これに限らず、設置される建物Ｂの条件や環境に応じて、輪郭において正方形、円形又は異形のものであってもよいし、縦横比で横長のものであってもよい。要するに、障子３０を開放したときに窓１０の室外側と室内側が連通するように、余剰空間部２１ａ，２２ａ及び室内側開口部２６が設けられていればよい。余剰空間部２１ａ，２２ａ及び室内側開口部２６の形状も、窓枠２０及び障子３０の形状に応じて適宜なものを採用することができる。 As shown in FIG. 3, the window frame 20 is formed in a vertically long rectangle with an aspect ratio when viewed from the front. The shape of the window frame 20 when viewed from the front is not limited to this, and depending on the conditions and environment of the building B in which it is installed, the contour may be square, circular, or irregular, or may be long in aspect ratio. may be In short, it is sufficient that the surplus spaces 21a and 22a and the indoor opening 26 are provided so that the outdoor side and the indoor side of the window 10 communicate with each other when the shoji 30 is opened. The shapes of the surplus space portions 21 a and 22 a and the indoor-side opening portion 26 can also be appropriately selected according to the shape of the window frame 20 and the shoji screen 30 .
　窓１０は、窓１０の外側を通行する通行人からの視線を気にせずに通風換気のために開放できることに主眼としていることから、図３に示すように、余剰空間部２１ａ，２２ａは、通行人の一般的な視線の高さに対応することとなる窓枠２０の左右、すなわち、右枠２３及び左枠２４と障子３０の間ではなく、通行人の一般的な視線の高さに対応しない窓枠２０の上下、すなわち、上枠２１及び下枠２２と障子３０の間に設けられている。 The main purpose of the window 10 is that it can be opened for ventilation without worrying about the line of sight of passers-by passing through the outside of the window 10. Therefore, as shown in FIG. The left and right sides of the window frame 20, that is, between the right and left frames 23 and 24 and the shoji 30, which correspond to the height of the general line of sight of passers-by, are not at the height of the general line of sight of passers-by. It is provided above and below the window frame 20 that does not correspond, that is, between the upper frame 21 and the lower frame 22 and the shoji 30 .
　障子３０は、障子３０と窓枠２０との間に介設された移動機構４０によって移動させられるが、第１実施形態では、移動機構４０は、障子３０が窓枠２０に対し平行して開放されるように、障子３０の全体をスライド可能に移動させる。 The shoji 30 is moved by a moving mechanism 40 interposed between the shoji 30 and the window frame 20. In the first embodiment, the moving mechanism 40 moves the shoji 30 parallel to the window frame 20. The entire shoji 30 is slidably moved so as to be carried out.
　具体的には、図３に示すように、窓枠２０の左右、すなわち、右枠２３及び左枠２４と障子３０の間には、障子３０の移動に必要となる間隙が設けられており、この間隙の四隅（図中、室内側開口部２６の四隅の外側近傍）には、障子３０を移動させるための移動機構４０として、障子ガイドレール４１と、障子ガイドレール４１に係合するハウジング４２が配置されている。障子ガイドレール４１は、右枠２３及び左枠２４の上下において余剰空間部２１ａ，２２ａが確保される位置に設けられる。ハウジング４２は、障子３０の四隅にそれぞれ固定された状態で障子ガイドレール４１に対しスライド可能に係合することとなり、ハウジング４２に設けられているネジの締め付けによって障子ガイドレール４１への係合ひいては摩擦力の強度を調節可能である。障子ガイドレール４１は、室外側開口部２９の周縁と上背枠２５又は下背枠２７との間に延在しており、障子３０は、それらによって移動する範囲が規制される。 Specifically, as shown in FIG. 3, between the left and right of the window frame 20, that is, between the right frame 23 and the left frame 24 and the shoji 30, a gap necessary for moving the shoji 30 is provided. Shoji guide rails 41 and housings 42 engaged with the shoji guide rails 41 are provided at the four corners of this gap (near the four corners of the indoor opening 26 in the figure) as a moving mechanism 40 for moving the shoji 30. are placed. The shoji guide rail 41 is provided at a position where surplus spaces 21a and 22a are secured above and below the right frame 23 and the left frame 24, respectively. The housings 42 are slidably engaged with the shoji guide rails 41 while being fixed to the four corners of the shoji 30, respectively. The strength of the frictional force is adjustable. The shoji guide rails 41 extend between the periphery of the outdoor opening 29 and the upper back frame 25 or the lower back frame 27, and the range of movement of the shoji 30 is restricted by them.
　第１実施形態では、移動機構４０をスライド機構とした場合について説明しているが、移動機構４０は、これに限定されるものではない。例えば、複数のリンク片を組み合わせたリンク機構や、前後方向に伸縮するアーム機構を採用してもよい。要するに、窓枠２０の室外側と室内側を往復可能な移動機構４０とすることも可能である。ただし、障子３０の操作性、特に、前後方向の移動に要する力を調節可能な点でスライド機構が好ましい。 Although the moving mechanism 40 is a slide mechanism in the first embodiment, the moving mechanism 40 is not limited to this. For example, a link mechanism that combines a plurality of link pieces or an arm mechanism that extends and contracts in the front-rear direction may be employed. In short, it is also possible to make the moving mechanism 40 capable of reciprocating between the outdoor side and the indoor side of the window frame 20 . However, the slide mechanism is preferable in terms of the operability of the shoji 30, especially the force required for the movement in the front-rear direction.
　障子３０は、図４に示すように、背面視（正面視も同様）において、例えば、正方形に形成されている。ここでは、縦長の窓枠２０に対して障子３０を正方形としているが、障子３０の背面視（正面視）の形状は、これに限らず、設置される建物Ｂの条件や環境に応じて、輪郭において矩形、円形又は異形のものであってもよいし、縦横比で縦長又は横長のものであってもよい。例えば、窓枠２０が正方形である場合、その上下に余剰空間部２１ａ，２２ａを確保すると、障子３０は縦横比において横長の矩形となる。 As shown in FIG. 4, the shoji 30 is, for example, square when viewed from the rear (the same is true for the front view). Here, the shoji 30 is square with respect to the vertically long window frame 20, but the shape of the shoji 30 when viewed from the rear (front view) is not limited to this. It may have a rectangular, circular or irregular shape in outline, and may have a vertical or horizontal aspect ratio. For example, when the window frame 20 has a square shape, if extra space portions 21a and 22a are secured above and below the window frame 20, the shoji 30 will have a horizontally long rectangular aspect ratio.
　障子３０の右框３３及び左框３４の背面の中央には、障子３０を窓枠２０にロックするとともに、前後方向に障子３０を移動させるときの把手となるカムラッチハンドル３６が設けられている。カムラッチハンドル３６は、ハンドル本体が縦状態で「閉」、横状態で「開」となるように設けられており、縦状態において、ハンドル本体に交差する方向に延在する施錠片が窓枠２０の背面に設けられている係止部材に係止することにより、障子３０を窓枠２０にロックする。 A cam latch handle 36 is provided at the center of the back surface of the right frame 33 and the left frame 34 of the shoji 30 to lock the shoji 30 to the window frame 20 and to serve as a handle for moving the shoji 30 in the front-rear direction. . The cam latch handle 36 is provided so that the handle body is "closed" in the vertical state and "open" in the horizontal state. The shoji 30 is locked to the window frame 20 by engaging with a locking member provided on the back surface of the door 20. - 特許庁
　なお、図４では、位置関係を説明するため、障子３０の右框３３及び左框３４の上下には移動機構４０としての障子ガイドレール４１と、障子ガイドレール４１に係合するハウジング４２が図示されている。 In addition, in FIG. 4, in order to explain the positional relationship, a shoji guide rail 41 as a moving mechanism 40 and a housing 42 that engages with the shoji guide rail 41 are shown above and below the right frame 33 and left frame 34 of the shoji 30. It is
　以上の構造を踏まえ、窓１０における通風換気について説明する。障子３０は、図５及び図６に示すように、窓枠２０の室外側と室内側で前後方向に移動する（図５及び図６中、実線白矢印参照）。前述のとおり、窓枠２０の前面（室外側開口部２９）は、窓１０が設けられる建物Ｂの外壁の外面と実質的にほぼ同一面に位置するように配置されるが、障子３０も、最大限開放したときに、建物Ｂの外壁の外面と実質的にほぼ同一面に位置する。 Based on the above structure, the ventilation at the window 10 will be explained. As shown in FIGS. 5 and 6, the shoji 30 moves forward and backward on the outside and inside of the window frame 20 (see solid white arrows in FIGS. 5 and 6). As described above, the front surface of the window frame 20 (outdoor opening 29) is arranged so as to be substantially flush with the outer surface of the outer wall of the building B in which the window 10 is provided. It is positioned substantially flush with the outer surface of the outer wall of building B when opened to the maximum extent.
　障子３０が窓枠２０の室内側開口部２６から室外側開口部２９に向かって移動して開放されたとき、余剰空間部２１ａ，２２ａと室内側開口部２６を介して、窓１０の室外側と室内側は連通し、通風換気が行われる（図５中、破線白矢印参照）。障子３０は、窓枠２０の室内側と室外側との間で、窓枠２０に対し無段階に停止可能に設けられている。通風換気に際しては、建物Ｂに設けられている他の窓などとの相対的関係によって、空気Ａは、室外側から室内側へ、又は、室内側から室外側へ、流通することとなる。空気Ａの流れは、余剰空間部２１ａ，２２ａと室内側開口部２６の上下の位置関係が平行ではないため、実際上は図中の破線白矢印で示したほどシャープではないものの、緩やかなクランク状となる。 When the shoji 30 moves from the indoor-side opening 26 of the window frame 20 toward the outdoor-side opening 29 and is opened, the outdoor side of the window 10 passes through the redundant space portions 21a and 22a and the indoor-side opening 26. and the indoor side communicate with each other, and ventilation is performed (see the broken white arrow in FIG. 5). The shoji 30 is provided so as to be steplessly stopable with respect to the window frame 20 between the indoor side and the outdoor side of the window frame 20.例文帳に追加During ventilation, the air A flows from the outdoor side to the indoor side or from the indoor side to the outdoor side depending on the relative relationship with other windows provided in the building B. Since the vertical positional relationship between the surplus spaces 21a and 22a and the room-side opening 26 is not parallel, the flow of the air A is actually not as sharp as indicated by the dashed white arrow in the figure, but it is a gentle crank. shape.
　図５及び図６では、防犯機構５０として、窓枠２０の室外側に網戸付き面格子５１を設けた例を示している。図７に、正面から見た網戸付き面格子５１の外観を示す。網戸付き面格子５１は、面格子５１（狭義の意味で面格子５１ということがある）と、面格子５１に取り付けられた網戸５２とから構成される。窓１０は、最大限開放した状態の障子３０が建物Ｂの外壁の外面と実質的にほぼ同一面に位置するように配置されることから建物Ｂの外壁の外面から外側に突出する態様の窓に比べて防犯性に優れているが、面格子５１を付加することによって防犯性をより一層向上させることができる。また、網戸付き面格子５１とすれば、特に夏季における防虫性を併せて達成することができる。ただし、面格子５１と網戸５２は、別々に設けてもよく、例えば、窓枠２０の室外側には面格子５１のみを設けておき、窓枠２０の室内側に巻取り式の網戸５２を設けるようにしてもよい。 FIG. 5 and FIG. 6 show an example in which a surface lattice 51 with a screen door is provided on the outdoor side of the window frame 20 as the crime prevention mechanism 50 . FIG. 7 shows the appearance of the screen door-equipped lattice 51 viewed from the front. The screen door-equipped screen door 51 is composed of a screen door 51 (sometimes referred to as a screen door 51 in a narrow sense) and a screen door 52 attached to the screen door 51 . The window 10 is arranged so that the shoji 30 in the maximum open state is substantially flush with the outer surface of the outer wall of the building B, so that the window 10 projects outward from the outer surface of the outer wall of the building B. However, by adding the surface lattice 51, the crime prevention performance can be further improved. Moreover, if the surface lattice 51 with a screen door is used, it is also possible to achieve insect repellency especially in summer. However, the lattice 51 and the screen door 52 may be provided separately. For example, only the lattice 51 is provided on the outdoor side of the window frame 20, and the roll-up screen door 52 is provided on the indoor side of the window frame 20. You may make it provide.
　なお、図５では、説明の便宜上、開放状態における障子３０のカムラッチハンドル３６を省略しているが、図６に示すように、カムラッチハンドル３６は、横状態で位置している。 In FIG. 5, for convenience of explanation, the cam latch handle 36 of the shoji 30 in the open state is omitted, but as shown in FIG. 6, the cam latch handle 36 is positioned horizontally.
　余剰空間部２１ａ，２２ａは、図５に示すように、縦断面視において、室外側開口部２９の一部として、室内側から室外側に向かって開口する。余剰空間部２１ａ，２２ａの外側の輪郭は窓枠２０の輪郭によって画定されるが、その具体的な形状については種々のものとしてよい。図５では、室内側開口部２６の周縁（上縁、下縁）から室外側開口部２９の周縁（上縁、下縁）に向かって、段状（ここでは、Ｌ字状）とした場合を示している。補足すれば、略水平方向の上枠２１と略垂直方向の上背枠２５の二辺、及び、同じく略水平方向の下枠２２と略垂直方向の下背枠２７の二辺がそれぞれ交差することによって、余剰空間部２１ａ，２２ａの外側の輪郭が段状（ここでは、Ｌ字状）となっている。 As shown in FIG. 5, the surplus spaces 21a and 22a open from the indoor side toward the outdoor side as part of the outdoor side opening 29 in a vertical cross-sectional view. The outer contours of the surplus spaces 21a and 22a are defined by the contour of the window frame 20, but the specific shape thereof may vary. In FIG. 5 , when stepped (here, L-shaped) from the peripheral edge (upper edge, lower edge) of the indoor side opening 26 toward the peripheral edge (upper edge, lower edge) of the outdoor side opening 29 is shown. Supplementally, the two sides of the substantially horizontal upper frame 21 and the substantially vertical upper back frame 25, and the two sides of the substantially horizontal lower frame 22 and the substantially vertical lower back frame 27 respectively intersect. As a result, the outer contours of the surplus spaces 21a and 22a are stepped (here, L-shaped).
　この点、窓１０では、前述のとおり、空気Ａの流れが緩やかなクランク状となることから、図８に示すように、縦断面視において、風誘導面としての余剰空間部２１ａ，２２ａの外側の輪郭を滑らかにすることを考慮し、室内側開口部２６の周縁から室外側開口部２９の周縁に向かって、上枠２１及び下枠２２を斜線状又は円弧状としてもよい。これにより、空気Ａの流れを相対的にスムーズに誘導することが可能となる。なお、窓１０のデザイン上の要請などにより、通風換気に支障のない範囲で、段状、斜線状又は円弧状の組合せによって上枠２１及び下枠２２を形成してもよい。 In this regard, in the window 10, as described above, the flow of the air A is in a gentle crank shape, so as shown in FIG. The upper frame 21 and the lower frame 22 may be shaped obliquely or arcuately from the rim of the indoor opening 26 toward the rim of the outdoor opening 29 in consideration of smoothing the contours of . This makes it possible to guide the flow of the air A relatively smoothly. Depending on the design requirements of the window 10, the upper frame 21 and the lower frame 22 may be formed in a combination of steps, oblique lines, or arcs as long as ventilation is not hindered.
　以上、窓１０の構成について説明したが、窓１０が設置される条件や環境によっては、障子３０の開放時に、余剰空間部２１ａ，２２ａ及び室内側開口部２６を通して、建物Ｂの室内に通行人の視線が届くことも考えられる。そこで、図９から図１２を参照して、窓１０の遮視性について、説明する。 Although the configuration of the window 10 has been described above, depending on the conditions and environment in which the window 10 is installed, when the shoji 30 is opened, a passerby may enter the room of the building B through the surplus spaces 21a and 22a and the indoor opening 26. It is also conceivable that the line of sight of Therefore, the visibility of the window 10 will be described with reference to FIGS. 9 to 12. FIG.
　図９から図１２は、窓１０と通行人Ｐ（身長Ｈ１を１７０ｃｍ程度と想定）の視線の関係について、４つのケースを図示している。 FIGS. 9 to 12 illustrate four cases regarding the line-of-sight relationship between the window 10 and the passerby P (whose height H1 is assumed to be about 170 cm).
　図９は、窓１０の上下長さＬが相対的に長く（１６０ｃｍ程度と想定）、余剰空間部２１ａ，２２ａが曲尺状（Ｌ字状）の場合を図示している。上下方向中心高さＨ２は１５０ｃｍ程度を想定している。この例では、上枠２１内側の余剰空間部２１ａと室内側開口部２６を通して建物Ｂの室内側が見える範囲（上の視界）は、視線Ｕ１（開放状態の障子３０の上桟３１の上縁と窓枠２０の室内側開口部２６の上縁とを結ぶ線）と視線Ｕ３（余剰空間部２１ａの室外側先端＜室外側開口部２０の周縁＞と開放状態の障子３０の上桟３１の上縁とを結ぶ線）を境界線とする範囲となる。この範囲には、視線Ｕ２（余剰空間部２１ａの室外側先端と窓枠２０の室内側開口部２６の上縁とを結ぶ線）が含まれる。同様に、下枠２２内側の余剰空間部２２ａと室内側開口部２６を通して建物Ｂの室内側が見える範囲（下の視界）は、視線Ｄ１（開放状態の障子３０の下桟３２の下縁と窓枠２０の室内側開口部２６の下縁とを結ぶ線）と視線Ｄ３（余剰空間部２２ａの室外側先端と開放状態の障子３０の下桟３２の下縁とを結ぶ線）に囲われた範囲となる。この範囲には、視線Ｄ２（余剰空間部２２ａの室外側先端と窓枠２０の室内側開口部２６の下縁とを結ぶ線）が含まれる。 FIG. 9 illustrates a case where the vertical length L of the window 10 is relatively long (assumed to be about 160 cm) and the surplus spaces 21a and 22a are curved (L-shaped). The center height H2 in the vertical direction is assumed to be approximately 150 cm. In this example, the range (upper visibility) where the interior of the building B can be seen through the surplus space 21a inside the upper frame 21 and the interior opening 26 is the line of sight U1 (the upper edge of the upper rail 31 of the shoji 30 in the open state). A line connecting the upper edge of the indoor-side opening 26 of the window frame 20) and the line of sight U3 (the outdoor-side tip of the surplus space 21a <peripheral edge of the outdoor-side opening 20> and the upper crosspiece 31 of the open shoji 30 The line connecting the edge) is the boundary line. This range includes the line of sight U2 (the line connecting the outdoor-side tip of the surplus space 21a and the upper edge of the indoor-side opening 26 of the window frame 20). Similarly, the range (lower visibility) where the interior of the building B can be seen through the surplus space 22a inside the lower frame 22 and the interior opening 26 is the line of sight D1 (the lower edge of the lower rail 32 of the shoji 30 in the open state and the window A line connecting the lower edge of the indoor-side opening 26 of the frame 20) and a line of sight D3 (a line connecting the outdoor-side tip of the surplus space 22a and the lower edge of the lower beam 32 of the shoji 30 in the open state). range. This range includes the line of sight D2 (the line connecting the outdoor-side tip of the surplus space 22a and the lower edge of the indoor-side opening 26 of the window frame 20).
　この例では、図９に示すように、余剰空間部２１ａ，２２ａ及び室内側開口部２６を通した視界が形成されるが、通常の通行人Ｐの視線は、窓１０の上下ともに視界から外れることになる。この場合、障子３０の上桟３１及び下桟３２の上下方向の幅を狭く設定することができる。 In this example, as shown in FIG. 9, a field of view is formed through the surplus spaces 21a and 22a and the room-side opening 26, but the line of sight of a normal passer-by P is out of the field of view both above and below the window 10. It will be. In this case, the vertical width of the upper crosspiece 31 and the lower crosspiece 32 of the shoji 30 can be set narrow.
　図１０は、図９に対し、窓１０の上下長さＬが相対的に短い（１１５ｃｍ程度と想定）場合を図示している。上下方向中心高さＨ２は１４０ｃｍ程度を想定している。この例では、窓１０の上下の視界を規定する、余剰空間部２１ａ，２２ａの室外側先端と、上桟３１の上縁及び下桟３２の下縁が通行人Ｐの視線の位置に近くなることから、通行人Ｐの身長Ｈ１によっては、余剰空間部２１ａ，２２ａと室内側開口部２６を通して建物Ｂの室内側が見える可能性が高まる。そこで、図１０では、窓１０の上下ともに視界が形成されないように、すなわち、境界線となる複数の視線が形成されないように、窓１０の上については、視線Ｕ１（余剰空間部２１ａの室外側先端と開放状態の障子３０の上桟３１の上縁と窓枠２０の室内側開口部２６の上縁とを結ぶ線）に、窓１０の下については、視線Ｄ１（余剰空間部２２ａの室外側先端と開放状態の障子３０の下桟３２の下縁と窓枠２０の室内側開口部２６の下縁とを結ぶ線）に、それぞれ一本化している。 FIG. 10 illustrates a case where the vertical length L of the window 10 is relatively short (assumed to be about 115 cm) compared to FIG. The center height H2 in the vertical direction is assumed to be approximately 140 cm. In this example, the ends of the excess spaces 21a and 22a, the upper edge of the upper rail 31, and the lower edge of the lower rail 32, which define the upper and lower fields of view of the window 10, are close to the line of sight of the passerby P. Therefore, depending on the height H1 of the passerby P, the possibility that the interior of the building B can be seen through the surplus spaces 21a and 22a and the interior opening 26 increases. Therefore, in FIG. 10, the line of sight U1 (the outdoor side of the surplus space 21a) is set above the window 10 so that the field of view is not formed both above and below the window 10, that is, so that a plurality of lines of sight that serve as boundaries are not formed. A line connecting the top edge of the shoji 30 in the open state and the upper edge of the upper beam 31 of the shoji 30 and the upper edge of the room-side opening 26 of the window frame 20), and below the window 10, the line of sight D1 (the room of the surplus space 22a). A line that connects the outer tip, the lower edge of the lower rail 32 of the shoji 30 in the open state, and the lower edge of the indoor-side opening 26 of the window frame 20).
　この例では、図１０に示すように、障子３０の上桟３１及び下桟３２の上下方向の幅を広く設定することにより、窓１０の上下における視線を一本化し、余剰空間部２１ａ，２２ａ及び室内側開口部２６を通した視界は形成されない。 In this example, as shown in FIG. 10, by setting the width of the upper beam 31 and the lower beam 32 of the shoji 30 in the vertical direction to be wide, the line of sight above and below the window 10 is unified, and the surplus spaces 21a and 22a are formed. And the view through the interior opening 26 is not formed.
　図１１は、図１０に対し、窓１０の上下長さＬが相対的に短い（９７ｃｍ程度と想定）場合を図示している。上下方向中心高さＨ２は１４０ｃｍ程度を想定している。この例では、図１０に示した視線の一本化を窓１０の上に限っており、その趣旨は、通行人Ｐとして成人を想定し、身長Ｈ１の低い子供の視線にはあえて対処しない例ということができる。この例では、窓１０の上については、視線Ｕ１（余剰空間部２１ａの室外側先端と開放状態の障子３０の上桟３１の上縁と窓枠２０の室内側開口部２６の上縁とを結ぶ線）に一本化することによって視界が形成されず、窓１０の下については、視線Ｄ１（開放状態の障子３０の下桟３２の下縁と窓枠２０の室内側開口部２６の下縁とを結ぶ線）と視線Ｄ３（余剰空間部２２ａの室外側先端と開放状態の障子３０の下桟３２の下縁と窓枠２０の室内側開口部２６に対応する建物Ｂの額縁の室内側とを結ぶ線）に囲われた視界が形成されることとなる。 FIG. 11 illustrates a case where the vertical length L of the window 10 is relatively short (assumed to be about 97 cm) compared to FIG. The center height H2 in the vertical direction is assumed to be approximately 140 cm. In this example, the unification of the line of sight shown in FIG. 10 is limited to the top of the window 10. The purpose of this is to assume that the passerby P is an adult, and that the line of sight of a child with a short height H1 is not dealt with. It can be said that In this example, above the window 10, the line of sight U1 (the tip of the outdoor side of the surplus space 21a, the upper edge of the upper rail 31 of the shoji 30 in the open state, and the upper edge of the indoor opening 26 of the window frame 20) The line of sight is not formed under the window 10, and the line of sight D1 (the lower edge of the lower crosspiece 32 of the shoji 30 in the open state and the room-side opening 26 of the window frame 20) edge) and the line of sight D3 (outdoor-side tip of the surplus space 22a, the lower edge of the lower beam 32 of the shoji 30 in the open state, and the room of the frame of the building B corresponding to the indoor-side opening 26 of the window frame 20) A field of view surrounded by a line connecting the inside is formed.
　この例では、図１１に示すように、障子３０の上桟３１の上下方向の幅を広く設定することにより、窓１０の上における視線を一本化し、余剰空間部２１ａ及び室内側開口部２６を通した視界は形成されない。一方、障子３０の下桟３２の上下方向の幅は狭く設定することにより、余剰空間部２２ａ及び室内側開口部２６を通した視界は形成される。 In this example, as shown in FIG. 11, by setting the upper crosspiece 31 of the shoji 30 wide in the vertical direction, the line of sight above the window 10 is unified, and the surplus space 21a and the indoor opening 26 are arranged. A view through is not formed. On the other hand, by setting the vertical width of the lower crosspiece 32 of the shoji 30 narrowly, a field of view through the extra space 22a and the interior opening 26 is formed.
　図１２は、窓１０の上下長さＬが相対的に短く（９５ｃｍ程度と想定）、上枠２１内側の余剰空間部２１ａが曲尺状（Ｌ字状）、下枠２２内側の余剰空間部２２ａが斜線状の場合を図示している。上下方向中心高さＨ２は１３０ｃｍ程度を想定している。この例では、窓１０の上においては、図１０及び図１１に対し、障子３０の上桟３１の上下方向の幅を広く設定していないため、視線Ｕ１（開放状態の障子３０の上桟３１の上縁と窓枠２０の室内側開口部２６の上縁とを結ぶ線）と視線Ｕ３（余剰空間部２１ａの室外側先端と開放状態の障子３０の上桟３１の上縁とを結ぶ線）を境界線とする視界が形成される。また、窓１０の下においては、図１１と同様に、視線Ｄ１（開放状態の障子３０の下桟３２の下縁と窓枠２０の室内側開口部２６の下縁とを結ぶ線）と視線Ｄ３（余剰空間部２２ａの室外側先端と窓枠２０の室内側開口部２６に対応する建物Ｂの額縁の室内側とを結ぶ線）を境界線とする視界が形成される。 12, the vertical length L of the window 10 is relatively short (assumed to be about 95 cm), the surplus space 21a inside the upper frame 21 is curved (L-shaped), and the surplus space 22a inside the lower frame 22. is oblique. The center height H2 in the vertical direction is assumed to be approximately 130 cm. In this example, above the window 10, the width of the upper beam 31 of the shoji 30 in the vertical direction is not set wider than in FIGS. A line connecting the upper edge and the upper edge of the indoor-side opening 26 of the window frame 20) and a line of sight U3 (a line connecting the outdoor-side tip of the surplus space 21a and the upper edge of the upper beam 31 of the shoji 30 in the open state) ) is formed as a boundary line. Under the window 10, as in FIG. 11, the line of sight D1 (the line connecting the lower edge of the lower crosspiece 32 of the shoji 30 in the open state and the lower edge of the interior-side opening 26 of the window frame 20) and the line of sight A field of view is formed with a boundary line D3 (a line connecting the outside edge of the surplus space 22a and the inside of the frame of building B corresponding to the inside opening 26 of the window frame 20).
　この例では、図１２に示すように、障子３０の上桟３１の上下方向の幅をやや広めに設定することにより、余剰空間部２１ａ及び室内側開口部２６を通した視界を狭め、通行人Ｐが平均的な身長Ｈ１の成人であれば、その視線は、窓１０の上の視界から外れることになる。一方、障子３０の下桟３２の上下方向の幅は狭く設定することにより、余剰空間部２２ａ及び室内側開口部２６を通した視界は形成される。 In this example, as shown in FIG. 12, by setting the width of the upper crosspiece 31 of the shoji 30 in the vertical direction to be slightly wider, the field of view through the surplus space 21a and the indoor opening 26 is narrowed, thereby If P is an adult of average height H1, his line of sight will be out of sight above window 10 . On the other hand, by setting the vertical width of the lower crosspiece 32 of the shoji 30 narrowly, a field of view through the extra space 22a and the interior opening 26 is formed.
　窓１０の遮視性については、上述したように、窓１０と建物Ｂとの相対的な位置関係や窓１０の仕様などによって種々の対応を取ることが可能であるが、通行人Ｐの視線がどうしても窓１０の視界に含まれてしまうような場合に備えて、窓１０の通風換気性と遮視性の両立を図る範囲で、障３０が窓枠２０の室内側開口部２６から室外側開口部２９に向かって移動して開放されたときに余剰空間部２１ａ，２２ａにおける遮視性を向上させる遮視機構６０を更に備えてもよい。 Regarding the visibility of the window 10, as described above, it is possible to take various measures depending on the relative positional relationship between the window 10 and the building B and the specifications of the window 10. In preparation for the case where the is inevitably included in the field of vision of the window 10, the barrier 30 is separated from the indoor side opening 26 of the window frame 20 to the outdoor side within the range of achieving both ventilation and visibility of the window 10. A shielding mechanism 60 that improves the shielding performance in the surplus spaces 21a and 22a when moved toward the opening 29 and opened may be further provided.
　図１３から図１６は、遮視機構６０の例として、遮視フラップ６２の２つのケースを図示している。図１３は遮視フラップ６２を示す縦断面図、図１４はその一部を拡大して示す斜視図、図１５は遮視フラップ６２の他の例を示す縦断面図、図１６はその一部を拡大して示す斜視図である。なお、これらの図は窓枠２０の上枠２１のみを図示しているが、必要に応じて、同様の遮視機構６０を窓枠２０の下枠２２に設けてもよい。 FIGS. 13 to 16 illustrate two cases of shielding flaps 62 as examples of the shielding mechanism 60. FIG. 13 is a longitudinal sectional view showing the shielding flap 62, FIG. 14 is a perspective view showing an enlarged part thereof, FIG. 15 is a longitudinal sectional view showing another example of the shielding flap 62, and FIG. 16 is a part thereof. 1 is an enlarged perspective view of FIG. Although these figures show only the upper frame 21 of the window frame 20, a similar shielding mechanism 60 may be provided on the lower frame 22 of the window frame 20 as required.
　遮視機構６０は、図１３に示すように、窓枠２０の右枠２３及び左枠２４の余剰空間部２１ａに対応する位置に設けられた一対のフラップガイドレール６１と、フラップガイドレール６１にスライド可能に係合し、障子３０の前後方向の移動に伴ってフラップガイドレール６１に沿って前後方向に移動する遮視フラップ６２とを備える。 As shown in FIG. 13, the shielding mechanism 60 includes a pair of flap guide rails 61 provided at positions corresponding to the surplus spaces 21a of the right frame 23 and the left frame 24 of the window frame 20, and the flap guide rails 61. and a shielding flap 62 that is slidably engaged and moves in the front-rear direction along the flap guide rail 61 as the shoji 30 moves in the front-rear direction.
　フラップガイドレール６１は、遮視フラップ６２がカバーする範囲を残し、窓枠２０の室内側から室外側に向かってやや下向きに傾斜するように延在している。左右一対のフラップガイドレール６１の間には空間が拡がっており、通風換気の妨げにはならない。一方、遮視フラップ６２は、板状の部材であり、視界を遮る。遮視フラップ６２は、後述するように、障子３０の上桟３１の頂部に可倒に取り付けられており、障子３０の閉鎖状態では、上背枠２５に沿って起立しており、障子３０の開放状態では、余剰空間部２１ａと室内側開口部２６を通した視界の一部を遮るように室内側から室外側に向かってやや下向きに傾斜する。 The flap guide rail 61 extends so as to incline slightly downward from the indoor side of the window frame 20 toward the outdoor side, leaving a range covered by the shielding flap 62 . A space is widened between the pair of left and right flap guide rails 61, which does not hinder ventilation. On the other hand, the blocking flap 62 is a plate-like member and blocks the field of view. As will be described later, the shielding flap 62 is attached to the top of the upper rail 31 of the shoji 30 so as to be foldable. In the open state, it inclines slightly downward from the indoor side to the outdoor side so as to partially block the view through the surplus space portion 21a and the indoor side opening portion 26. - 特許庁
　図１３は、図９における視界を例として、障子３０が室外側いっぱいに開放されたときの遮視フラップ６２の遮視性を示している。遮視フラップ６２は、余剰空間部２１ａにおいて、視線Ｕ１（開放状態の障子３０の上桟３１の上縁＜遮視フラップ６２の室外側先端＞と窓枠２０の室内側開口部２６の上縁とを結ぶ線）、視線Ｕ３（余剰空間部２１ａの室外側先端と開放状態の障子３０の上桟３１の上縁＜遮視フラップ６２の室外側先端＞とを結ぶ線）、視線Ｕ２（余剰空間部２１ａの室外側先端と遮視フラップ６２の室内側先端と窓枠２０の室内側開口部２６の上縁とを結ぶ線）によって囲われた範囲の視界を遮ることとなる。 FIG. 13 shows the visibility of the shielding flap 62 when the shoji 30 is fully opened to the outside, taking the field of view in FIG. 9 as an example. In the surplus space 21a, the shielding flap 62 is positioned along the line of sight U1 (the upper edge of the upper beam 31 of the shoji 30 in the open state <outdoor-side tip of the shielding flap 62> and the upper edge of the indoor-side opening 26 of the window frame 20). ), the line of sight U3 (the line connecting the tip of the surplus space 21a on the outdoor side and the upper edge of the upper rail 31 of the shoji 30 in the open state <the tip of the outdoor side of the shielding flap 62>), the line of sight U2 (the surplus The line connecting the outdoor-side tip of the space 21a, the indoor-side tip of the shielding flap 62, and the upper edge of the indoor-side opening 26 of the window frame 20) obstructs the field of view in the area surrounded.
　図１４は、遮視フラップ６２の具体的な例を示している。遮視フラップ６２は、その上端（障子３０が開放されたとき＜図中、実線表示＞に室内側先端となる）に滑り部材６４が設けられており、滑り部材６４は、コの字状に形成されたフラップガイドレール６１に沿ってスライド可能である。遮視フラップ６２は、その下端（障子３０が開放されたとき＜図中、実線表示＞に室外側先端となる）において丁番６３を介して障子３０の上桟３１の頂部に取り付けられており、丁番３０は、障子３０の前後移動に応じて、遮視フラップ６２を上桟３１に対して可倒にする。これにより、遮視フラップ６２は、障子３０が開放されたとき＜図中、実線表示＞には視線を遮る方向に面するとともに、障子３０が閉鎖されたとき＜図中、破線表示＞には上背枠２５に沿って起立して、障子３０の開閉の妨げにならない。 FIG. 14 shows a specific example of the shielding flap 62. FIG. The shielding flap 62 is provided with a sliding member 64 at its upper end (when the shoji 30 is opened, it becomes the tip of the room inside <indicated by solid line in the figure>), and the sliding member 64 is formed in a U-shape. It is slidable along the formed flap guide rail 61 . The shielding flap 62 is attached to the top of the upper beam 31 of the shoji 30 via a hinge 63 at its lower end (the tip of the outdoor side when the shoji 30 is opened <indicated by the solid line in the figure>). , the hinge 30 allows the shielding flap 62 to be tilted with respect to the upper crosspiece 31 according to the longitudinal movement of the shoji 30. - 特許庁As a result, when the shoji 30 is opened <indicated by a solid line in the figure>, the shielding flap 62 faces the direction of blocking the line of sight, and when the shoji 30 is closed <indicated by a broken line in the figure> It stands up along the upper back frame 25 and does not interfere with the opening and closing of the shoji 30. - 特許庁
　図１５及び図１６は、遮視フラップ６２の他の例を示している。遮視機構６０は、窓１０の通風換気性と遮視性の両立を図ろうとするものであるが、この他の例では、遮視フラップ６２は板状の材質で形成されることを考慮し、遮視フラップ６２自体に通風換気性を持たせようとするものである。 15 and 16 show another example of the blocking flap 62. FIG. The shielding mechanism 60 is intended to achieve both ventilation and shielding properties of the window 10. In this other example, the shielding flap 62 is made of a plate-like material. , the shielding flap 62 itself is intended to have ventilation.
　すなわち、この他の例では、図１５及び図１６に示すように、遮視フラップ６２は、遮視フラップ６２が傾斜したときに重力で自然に開放する通風板６５を有している。通風板６５は、遮視フラップ６２が傾斜すると自然に鉛直方向に垂下するように、遮視フラップ６２に回動可能に取り付けられる。これにより、垂下した通風板６５によって遮視性が確保されるとともに、通風板６５が開放したことによって生じた空間を通して、通風換気が行われる。図１６に拡大して示すように、通風板６５は、障子３０が開放されたとき＜図中、実線表示＞には鉛直方向に垂下するとともに、障子３０が閉鎖されたとき＜図中、破線表示＞には遮視フラップ６２と一体的に上背枠２５に沿って起立して、障子３０の開閉の妨げにならない。 That is, in this other example, as shown in FIGS. 15 and 16, the shielding flap 62 has a ventilation plate 65 that naturally opens due to gravity when the shielding flap 62 is tilted. The ventilation plate 65 is rotatably attached to the shielding flap 62 so that it naturally hangs vertically when the shielding flap 62 is tilted. As a result, visibility is ensured by the hanging ventilation plate 65, and ventilation is performed through the space created by the opening of the ventilation plate 65. - 特許庁As shown in an enlarged view in FIG. 16, the ventilation plate 65 hangs down in the vertical direction when the shoji 30 is opened (indicated by solid line in the figure), and when the shoji 30 is closed (indicated by broken line in the figure). Display> stands along the upper back frame 25 integrally with the shielding flap 62 so as not to interfere with the opening and closing of the shoji 30.例文帳に追加
　以上、窓１０について説明したが、次のような変形も可能である。すなわち、建物Ｂの同じ部屋又は別の部屋に設けられている他の窓などとの相対的関係によって、１つの窓１０においては、上枠２１内側の余剰空間部２１ａと下枠２２内側の余剰空間部２２ａのいずれか１つを設けるような構成としてもよい。効率的な通風換気のためには、複数の窓、例えば、対角線上にある２つの窓を同時に開放することがあるため、そのような場合には、１つの窓１０に上枠２１内側の余剰空間部２１ａと下枠２２内側の余剰空間部２２ａの双方を必ずしも設けなくてもよく、少なくとも１箇所の余剰空間部２１ａ又は２２ａが設けられていればよい。 Although the window 10 has been described above, the following modifications are also possible. That is, depending on the relative relationship with other windows provided in the same room or another room of the building B, in one window 10, the surplus space part 21a inside the upper frame 21 and the surplus space part 21a inside the lower frame 22 A configuration in which one of the space portions 22a is provided may be employed. For efficient ventilation, a plurality of windows, for example, two windows on a diagonal line may be opened at the same time. It is not necessary to provide both the space 21a and the extra space 22a inside the lower frame 22, as long as at least one extra space 21a or 22a is provided.
　また、上記の説明では、窓枠２０の前面（室外側開口部２９）や最大限開放したときの障子３０の位置について、窓１０が設けられる建物Ｂの外壁の外面と実質的にほぼ同一面に位置するように配置されるとしたが、窓１０が設置される建物Ｂの仕様や建物Ｂの周囲の環境によっては必ずしもそのように限定しなくてもよい。例えば、窓枠２０の前面（室外側開口部２９）や最大限開放したときの障子３０は、窓１０と通行人Ｐとの距離が取れるよう場合には建物Ｂの外壁の外面から室外側に突出した位置に、また、外側の窓辺に花壇のスペースを設けるような場合には室内側に引き込まれた位置にくるように配置してもよい。 Further, in the above description, the front surface of the window frame 20 (outdoor opening 29) and the position of the shoji 30 when opened to the maximum are substantially flush with the outer surface of the outer wall of the building B in which the window 10 is provided. However, depending on the specifications of the building B in which the window 10 is installed and the surrounding environment of the building B, this need not necessarily be the case. For example, the front surface of the window frame 20 (outdoor opening 29) and the shoji screen 30 when opened to the maximum extent may extend from the outer surface of the outer wall of the building B to the outdoor side if the distance between the window 10 and the passerby P can be secured. It may be placed in a protruding position, or in the case of providing a flower bed space on the outside window side, it may be placed in a position pulled into the room.
（第２実施形態）
　以上、第１実施形態及びその変形例に係る窓１０を説明したが、次に、図１７から図２２を参照して、第２実施形態に係る窓１０Ａ，１０Ｂを説明する。第１実施形態に係る窓１０は、余剰空間部２１ａ，２２ａが窓枠２０の上枠２１内側及び／又は下枠２２内側に設けられる場合（すなわち、上枠２１内側のみ、下枠２２内側のみ、上枠２１内側及び下枠２２内側の双方の３つの態様）において、障子３０が窓枠２０に対し平行して開放されるように、移動機構４０が障子３０の全体をスライド可能に移動させる態様であるが、これに対し、第２実施形態に係る窓１０Ａ，１０Ｂは、余剰空間部２１ａ，２２ａが窓枠２０の上枠２１内側又は下枠２２内側に設けられる場合（すなわち、上枠２１内側のみ、下枠２２内側のみの２つの態様）において、障子３０が窓枠２０に対し上下方向に傾斜して開放されるように、移動機構４０が障子３０の上部又は下部を回動可能に移動させるものである。 (Second embodiment)
The window 10 according to the first embodiment and its modification has been described above. Next, windows 10A and 10B according to the second embodiment will be described with reference to FIGS. 17 to 22. FIG. In the window 10 according to the first embodiment, when the excess space portions 21a and 22a are provided inside the upper frame 21 and/or inside the lower frame 22 of the window frame 20 (that is, only inside the upper frame 21 and only inside the lower frame 22 , inside the upper frame 21 and inside the lower frame 22), the moving mechanism 40 slidably moves the entire shoji 30 so that the shoji 30 is opened parallel to the window frame 20. In contrast, the windows 10A and 10B according to the second embodiment are provided with the redundant space portions 21a and 22a inside the upper frame 21 or inside the lower frame 22 of the window frame 20 (that is, the upper frame 21 inside only, and lower frame 22 only inside), the movement mechanism 40 can rotate the upper or lower part of the shoji 30 so that the shoji 30 is tilted vertically with respect to the window frame 20 and opened. is to be moved to

The gist of the present invention is not limited to the embodiments shown in FIGS. 17 to 22, and various modifications can be made. Differences from the window 10 according to the first embodiment will be mainly described below.
　まず、窓１０Ａでは、図１７に示すように、窓枠２０の上枠２１内側の余剰空間部２１ａのみが設けられている。下枠２２内側には、通風換気を積極的に行うための余剰空間部２２ａは設けられていない。障子３０は、図１８に示すように、下桟３２の左右端に移動機構４０としてのヒンジ４３が設けられており、窓枠２０の右枠２３及び左枠２４の下部に回動可能に取り付けられる。障子３０の背面に設けられているカムラッチハンドル３６は、右框３３及び左框３４の上下方向中央から上桟３１寄りに位置している。 First, in the window 10A, as shown in FIG. 17, only the extra space 21a inside the upper frame 21 of the window frame 20 is provided. Inside the lower frame 22, there is no extra space 22a for positive ventilation. As shown in FIG. 18, the shoji 30 is provided with hinges 43 as a moving mechanism 40 at the left and right ends of the lower beam 32, and is rotatably attached to the lower portions of the right frame 23 and the left frame 24 of the window frame 20. be done. A cam latch handle 36 provided on the rear surface of the shoji 30 is positioned closer to the upper crosspiece 31 from the vertical center of the right frame 33 and the left frame 34 .
　以上の構造を踏まえ、窓１０Ａにおける通風換気について説明する。障子３０は、図１９に示すように、カムラッチハンドル３６を室外側に押し込むと、下桟３２に設けられているヒンジ４３を支点として、障子３０の上部である上桟３１が室内側開口部２６の周縁（上縁）から室外側へ回動可能に移動し（図１９中、実線白矢印参照）、窓枠２０に対し上下方向に傾斜して開放される。室外側へ移動した上桟３１は、最大限開放された状態で、窓枠２０の前面（室外側開口部２９）、ひいては、窓１０Ａが設けられる建物Ｂの外壁の外面と実質的にほぼ同一面に位置する。 Based on the above structure, the ventilation at the window 10A will be explained. As shown in FIG. 19, when the cam latch handle 36 of the shoji 30 is pushed to the outside of the room, the hinge 43 provided on the lower beam 32 serves as a fulcrum, and the upper beam 31, which is the upper part of the shoji 30, opens to the indoor side. 26 from the peripheral edge (upper edge) of 26 to the outdoor side (see the solid white arrow in FIG. 19), and tilts up and down with respect to the window frame 20 to be opened. The upper beam 31 moved to the outdoor side is substantially the same as the front surface of the window frame 20 (outdoor opening 29), and thus the outer surface of the outer wall of the building B where the window 10A is provided, in the maximum open state. located on the surface.
　障子３０の上桟３１が窓枠２０の室内側開口部２６から室外側開口部２９に向かって移動して開放されたとき、余剰空間部２１ａと室内側開口部２６を介して、窓１０Ａの室外側と室内側は連通し、通風換気が行われる（図１９中、破線白矢印参照）。通風換気に際しては、建物Ｂに設けられている他の窓などとの相対的関係によって、空気Ａは、室外側から室内側へ、又は、室内側から室外側へ、流通することとなる。空気Ａの流れは、余剰空間部２１ａと室内側開口部２６の上下の位置関係が平行ではないため、実際上は図中の破線白矢印で示したほどシャープではないものの、緩やかなクランク状となる。 When the upper beam 31 of the shoji 30 moves from the indoor-side opening 26 of the window frame 20 toward the outdoor-side opening 29 and is opened, the window 10A is opened through the surplus space 21a and the indoor-side opening 26. The outdoor side and the indoor side communicate with each other, and ventilation is performed (see the broken white arrow in FIG. 19). During ventilation, the air A flows from the outdoor side to the indoor side or from the indoor side to the outdoor side depending on the relative relationship with other windows provided in the building B. Since the vertical positional relationship between the excess space 21a and the room-side opening 26 is not parallel, the flow of the air A is actually not as sharp as indicated by the dashed white arrow in the figure, but has a gentle crank shape. Become.
　なお、ここでは、図示していないが、障子３０の上桟３１については、窓枠２０に対し自由となるように構成してもよいし、拘束されるように構成してもよい。障子３０の上桟３１を窓枠２０に対し自由とする場合には、窓枠２０の上桟３１が室外側開口部２９の位置で規制されるように、室外側開口部２９の周縁（上縁）に当接させるほか、窓枠２０にストッパーを設けたり、窓枠２０と障子３０を伸縮自在のアームで接続したりしてもよい。一方、拘束する場合には、第１実施形態に係る窓１０で示したような障子ガイドレール４１を右枠２３及び左枠２４に室内側から室外側に向かって下方に傾斜するように設けることによってハウジング４２を介してスライド可能としてもよい。この場合、障子ガイドレール４１は、室外側開口部２９の周縁と上背枠２５との間に延在しており、障子３０は、それらによって移動する範囲が規制される。 Although not shown here, the upper crosspiece 31 of the shoji 30 may be configured to be free with respect to the window frame 20, or may be configured to be constrained. When the upper beam 31 of the shoji 30 is set free with respect to the window frame 20 , the upper beam 31 of the window frame 20 is regulated at the position of the outdoor opening 29 . The window frame 20 may be provided with a stopper, or the window frame 20 and the shoji 30 may be connected by an extendable arm. On the other hand, when restraining, the shoji guide rail 41 shown in the window 10 according to the first embodiment is provided on the right frame 23 and the left frame 24 so as to be inclined downward from the indoor side to the outdoor side. may be slidable through the housing 42 by the . In this case, the shoji guide rails 41 extend between the periphery of the outdoor opening 29 and the upper back frame 25, and the range of movement of the shoji 30 is restricted by them.
　次に、窓１０Ｂでは、図２０に示すように、窓枠２０の下枠２２内側の余剰空間部２２ａのみが設けられている。上枠２１内側には、通風換気を積極的に行うための余剰空間部２１ａは設けられていない。障子３０は、図２１に示すように、上桟３１の左右端に移動機構４０としてのヒンジ４３が設けられており、窓枠２０の右枠２３及び左枠２４の上部に回動可能に取り付けられる。障子３０の背面に設けられているカムラッチハンドル３６は、右框３３及び左框３４の上下方向中央から下桟３２寄りに位置している。 Next, in the window 10B, as shown in FIG. 20, only an extra space 22a inside the lower frame 22 of the window frame 20 is provided. Inside the upper frame 21, there is no surplus space 21a for positive ventilation. As shown in FIG. 21, the shoji 30 is provided with hinges 43 as a moving mechanism 40 at the left and right ends of the upper crosspiece 31, and is rotatably attached to the upper part of the right frame 23 and the left frame 24 of the window frame 20. be done. A cam latch handle 36 provided on the rear surface of the shoji 30 is positioned closer to the lower rail 32 from the vertical center of the right frame 33 and the left frame 34 .
　以上の構造を踏まえ、窓１０Ｂにおける通風換気について説明する。障子３０は、図２２に示すように、カムラッチハンドル３６を室外側に押し込むと、上桟３１に設けられているヒンジ４３を支点として、障子３０の下部である下桟３２が室内側開口部２６の周縁（下縁）から室外側へ回動可能に移動し（図２２中、実線白矢印参照）、窓枠２０に対し上下方向に傾斜して開放される。室外側へ移動した下桟３２は、最大限開放された状態で、窓枠２０の前面（室外側開口部２９）、ひいては、窓１０Ｂが設けられる建物Ｂの外壁の外面と実質的にほぼ同一面に位置する。 Based on the above structure, the ventilation at the window 10B will be explained. As shown in FIG. 22, when the cam latch handle 36 of the shoji 30 is pushed to the outside of the room, the hinge 43 provided on the upper beam 31 serves as a fulcrum, and the lower beam 32, which is the lower part of the shoji 30, opens to the indoor side. 26 from the peripheral edge (lower edge) of 26 to the outside of the room (see the solid white arrow in FIG. 22), and tilts vertically with respect to the window frame 20 to be opened. The lower beam 32 moved to the outdoor side is substantially the same as the front surface of the window frame 20 (outdoor opening 29) and the outer surface of the outer wall of the building B in which the window 10B is provided in the maximum open state. located on the surface.
　障子３０の下桟３２が窓枠２０の室内側開口部２６から室外側開口部２９に向かって移動して開放されたとき、余剰空間部２２ａと室内側開口部２６を介して、窓１０Ｂの室外側と室内側は連通し、通風換気が行われる（図２２中、破線白矢印参照）。通風換気に際しては、建物Ｂに設けられている他の窓などとの相対的関係によって、空気Ａは、室外側から室内側へ、又は、室内側から室外側へ、流通することとなる。空気Ａの流れは、余剰空間部２２ａと室内側開口部２６の上下の位置関係が平行ではないため、実際上は図中の破線白矢印で示したほどシャープではないものの、緩やかなクランク状となる。 When the lower rail 32 of the shoji 30 moves from the indoor-side opening 26 of the window frame 20 toward the outdoor-side opening 29 and is opened, the window 10B is opened through the surplus space 22a and the indoor-side opening 26. The outdoor side and the indoor side communicate with each other, and ventilation is performed (see the broken white arrow in FIG. 22). During ventilation, the air A flows from the outdoor side to the indoor side or from the indoor side to the outdoor side depending on the relative relationship with other windows provided in the building B. Since the vertical positional relationship between the surplus space 22a and the room-side opening 26 is not parallel, the flow of the air A is actually not as sharp as indicated by the dashed white arrow in the figure, but has a gentle crank shape. Become.
　なお、ここでは、図示していないが、障子３０の下桟３２については、窓枠２０に対し自由となるように構成してもよいし、拘束されるように構成してもよい。障子３０の下桟３２を窓枠２０に対し自由とする場合には、窓枠２０の下桟３２が室外側開口部２９の位置で規制されるように、室外側開口部２９の周縁（下縁）に当接させるほか、窓枠２０にストッパーを設けたり、窓枠２０と障子３０を伸縮自在のアームで接続したりしてもよい。一方、拘束する場合には、第１実施形態に係る窓１０で示したような障子ガイドレール４１を右枠２３及び左枠２４に室内側から室外側に向かって上方に傾斜するように設けることによってハウジング４２を介してスライド可能としてもよい。この場合、障子ガイドレール４１は、室外側開口部２９の周縁と下背枠２７との間に延在しており、障子３０は、それらによって移動する範囲が規制される。 Although not shown here, the lower beam 32 of the shoji 30 may be configured to be free with respect to the window frame 20, or may be configured to be constrained. When the lower rail 32 of the shoji 30 is free from the window frame 20, the lower rail 32 of the window frame 20 is regulated at the position of the outdoor opening 29. The window frame 20 may be provided with a stopper, or the window frame 20 and the shoji 30 may be connected by an extendable arm. On the other hand, when restraining, the shoji guide rail 41 shown in the window 10 according to the first embodiment is provided on the right frame 23 and the left frame 24 so as to be inclined upward from the indoor side to the outdoor side. may be slidable through the housing 42 by the . In this case, the shoji guide rails 41 extend between the periphery of the outdoor opening 29 and the lower back frame 27, and the range of movement of the shoji 30 is restricted by them.
　窓１０Ａ，１０Ｂには、窓１０と同様に、防犯機構５０としての面格子５１又は網戸付き面格子５１を付加してもよく、また、遮視機構６０を付加してもよい。遮視機構６０については、上枠２１内側の余剰空間部２１ａが形成される窓１０Ａのみならず、下枠２２内側の余剰空間部２２ａが形成される窓１０Ｂについても、それらが設置される条件や環境において通行人Ｐ等からの視線を遮断する遮視性を向上させる必要がある場合には、窓１０Ａでは障子３０の上桟３１に、窓１０Ｂでは障子３０の下桟３２に設けることにしてもよい。 As with the window 10, the windows 10A and 10B may be provided with a screen lattice 51 or screened screen lattice 51 as a security mechanism 50, or may be provided with a shielding mechanism 60.
