Description

本発明は、開口部を塞ぐ網材を備えるサッシに関する。   The present invention relates to a sash including a net member that closes an opening.

従来、窓などの開口部から虫が侵入することを防ぐための網戸があるが、網戸は非使用時（障子閉鎖時）においても常に露出した状態であるため、眺望の妨げになることが問題であった。そこで、特許文献１に示すように、非使用時に網部が収納されるスクリーン装置が提案されている。この装置においては、網部を付勢巻き取り可能な収納ケースが枠体に摺動自在に取り付けてある。使用時には、まず障子を開き、続いて収納ケースを障子の竪框の位置まで摺動させる。網部の先端は竪枠に係止させてあるので、収納ケースの摺動に伴って網部が引き出され、開口部を塞ぐ。そして収納ケースは障子の竪框に固定する。また、障子を閉める際には、収納ケースを障子の竪框から取り外すと、網部を巻き取りながら竪枠側へ摺動するので、その後障子を閉めればよい。このようなスクリーン装置によれば、非使用時には網部が収納ケース内に収納されて露出しない状態となるため、眺望が妨げられない。   Conventionally, there are screen doors to prevent insects from entering through openings such as windows, but the screen doors are always exposed even when not in use (when shojis are closed), which can hinder the view. Met. Therefore, as shown in Patent Document 1, a screen device has been proposed in which a net portion is stored when not in use. In this apparatus, a storage case capable of energizing and winding the net portion is slidably attached to the frame. In use, the shoji is first opened, and then the storage case is slid to the position of the shoji's heel. Since the tip of the mesh part is locked to the frame, the mesh part is pulled out as the storage case slides to close the opening. And fix the storage case to the shoji paper bag. Moreover, when closing the shoji, if the storage case is removed from the shoji of the shoji, it slides to the hoist frame side while winding up the mesh portion. According to such a screen device, when not in use, the net portion is stored in the storage case and is not exposed, so that the view is not hindered.

特許第３３９１７１２号公報Japanese Patent No. 3391712

しかしながら、特許文献１の発明では、障子と網部を別々に開閉しなければならず、操作が面倒であった。また、網部には常に収納ケースに巻き取られる方向に付勢力が働いているので、この付勢力により、開いた障子が閉鎖方向に動くおそれがあった。そして、この巻き取りのための機構が故障するおそれもあった。さらに、網部を取り替える際には収納ケースを分解しなければならず、メンテナンス性がよくなかった。   However, in the invention of Patent Document 1, the shoji and the net portion must be opened and closed separately, and the operation is troublesome. Further, since the urging force always acts on the net portion in the direction of being wound around the storage case, the urging force may cause the open shoji to move in the closing direction. And the mechanism for this winding may also break down. Furthermore, when replacing the net part, the storage case had to be disassembled, and maintenance was not good.

本発明は、上記事情を鑑みたものであり、簡易な構成で操作が容易な網材を有し、非使用時には網材が露出しないサッシ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 an object of the present invention is to provide a sash that has a mesh material that can be easily operated with a simple configuration and that does not expose the mesh material when not in use.

本発明のうち請求項１の発明は、サッシ枠と、引戸障子と、網材と、戸先側取付材と、戸当側取付材とを備え、引戸障子は、サッシ枠に納めてあって開口幅が制限されており、戸先側取付材は、引戸障子の戸先側竪框の見付面に取り付けてあり、戸当側取付材は、引戸障子の戸先側竪框に対向するサッシ枠の竪枠の戸当部に隣接する位置に取り付けてあり、網材は、引戸障子の摺動方向に折り畳み自在であって、戸先側取付材と戸当側取付材の間に着脱自在に取り付けてあり、開口幅の制限を解除して引戸障子をさらに開くと、網材が戸先側取付材又は戸当側取付材から外れることを特徴とする。 The invention of claim 1 of the present invention comprises a sash frame, a sliding door shoji, a net, a door end side mounting material, and a door side mounting material, and the sliding door shoji is housed in the sash frame. The opening width is limited, and the door-end side mounting material is attached to the finding surface of the door-end side fence of the sliding door shoji, and the door-hold side mounting material faces the door-end side fence of the sliding door shoji is attached to a position adjacent to the door hook part of the vertical frame of the sash frame, Amizai are self standing folding the sliding direction of the sliding door shoji, during the door end side mounting member and Toto side mounting member removable Ri Oh and freely mounting, when releasing the restriction of the opening width further open the sliding door sliding door, the net material is characterized Rukoto off the door leading side mounting member or Toto side mounting member.

本発明のうち請求項１の発明によれば、障子の戸先側竪框に取り付けた戸先側取付材と、戸先側竪框に対向する戸当部に隣接して取り付けた戸当側取付材の間に網材を取り付けてあるので、障子を開けると網材も連動して広がり、障子を閉めると網材も連動して折り畳まれるため、操作が容易である。また、障子の開口幅が制限されており、網材の幅も短いので、伸張及び折り畳みの際に網材が撓むことはない。さらに、網材は戸先側取付材と戸当側取付材に対して着脱自在であるから、取り替えが容易でメンテナンス性がよい。また、網材を使用した状態で開口幅の制限を解除して障子を開きすぎた場合には、網材が容易に戸先側取付材又は戸当側取付材から外れるので、網材を損傷することもない。さらに、既存のサッシへの後付けも容易であり、枠の取り替えなども必要ないので、費用が抑えられる。 According to the invention of claim 1 of the present invention , the door-end side attachment material attached to the door-end side fence of the shoji and the door-hold side attached adjacent to the door-hold portion facing the door-end side fence Since the mesh material is attached between the attachment materials, the mesh material spreads in conjunction with opening the shoji, and the mesh material is folded in conjunction with closing the shoji, so that the operation is easy. Also, have limited opening width of disabled child, the width of the web material is short and does not mesh material flexes during the stretching and folding. Furthermore, since the mesh material is detachable from the door end side attachment material and the door stop side attachment material, replacement is easy and maintenance is good. In addition, if the opening width restriction is released with the mesh material used and the shoji is opened too much, the mesh material is easily detached from the door-end side mounting material or the door-holding side mounting material. I don't have to. Further, retrofitting to an existing sash is easy, and there is no need to replace the frame, thereby reducing costs.

In the following, left and right indicate the left and right direction when the sash is viewed from the indoor side. As shown in FIG. 5, the first embodiment of the sash is a sliding window in which two sliding door shojis (an outer shoji 2 a and an inner shoji 2 b) are placed in a sash frame 1 in a left-right manner. A frame 8 is provided on the indoor side of the sash frame 1. Each of the external shoji 2a and the inner shoji 2b is assembled on the inner circumference side by assembling the door end side hooks 21a and 21b, the door bottom side hooks 22a and 22b, the upper hooks 23a and 23b, and the lower hooks 24a and 24b. Glass panels 25a and 25b are fitted. As shown in FIG. 3, the glass panels 25a and 25b are made of double-glazed glass and have a large expected width, so that the panel holding portion on the inner peripheral side of each heel is on the outdoor side in the external obstacle 2a, and in the room on the internal obstacle 2b. Take it inside. And the groove | channel of the cross-sectional substantially U shape extended in the up-down direction is formed in the outdoor side surface and indoor side surface of the door-end side hooks 21a and 21b, and it takes a hand when opening and closing the external shoji 2a and the internal shoji 2b The clue part 211 is. Moreover, the stopper 6 is attached to the indoor side surface of the lower collar 24a of the external shoji 2a. The stopper 6 protrudes indoors by the urging force of the built-in spring. When the outer shoji 2a or the inner shoji 2b is opened, the door butt side heel 22b of the inner shoji 2b is moved to the stopper 6. It abuts so that it cannot be opened any more. In addition, the stopper 6 is provided near the door butt side of the lower arm 24a, and restricts the opening width of the external shoji 2a and the internal shoji 2b within a narrow range. Moreover, if the stopper 6 is pushed in against the urging force of the spring, the restriction is released and the outer obstacle 2a and the inner obstacle 2b can be opened widely. And in this embodiment, the net | network material 3 is provided in the indoor side of the external shoji 2a, and it explains in full detail below.

まず、図１〜図４に示すように、外障子２ａの戸先側竪框２１ａの室内側面に、戸先側取付材４を取り付けてある。戸先側取付材４は、戸先側竪框２１ａと略同じ上下長さを有するものであり、断面が室内外方向に長い矩形で中空の本体部４１と、本体部４１の左側面の室外側端から室外側に向けて突出する中空の嵌合部４２からなり、全体として断面略Ｌ字形である。本体部４１は、室外側面が戸先側竪框２１ａの室内側面に当接していて、室内側に向けて突出しており、嵌合部４２は、戸先側竪框２１ａの室内側の手掛部２１１に嵌合していて、手掛部２１１の底面にネジ止めしてある。そして、本体部４１の左側面の室内側寄りの位置には、左側に向けて突出する突出片４３を形成してあり、本体部４１の左側面の、嵌合部４２の室内側面と突出片４３の間部分が、網材３の取付面４４となっている。なお、本体部４１の室内側端は、突出片４３よりも室内側に延出しており、この延出部分は、戸先側取付材４の嵌合部４２によって塞がれた戸先側竪框２１ａの手掛部２１１の代わりとして機能する。   First, as shown in FIGS. 1 to 4, the door-end side attachment material 4 is attached to the indoor side surface of the door-end side ridge 21 a of the external shoji 2 a. The door-end side attachment material 4 has substantially the same vertical length as the door-end side flange 21a, and has a rectangular main body 41 having a long cross section in the indoor / outdoor direction, and a left side chamber of the main body 41. It consists of the hollow fitting part 42 which protrudes toward an outdoor side from an outer side end, and is a cross-sectional substantially L shape as a whole. The main body 41 has an outdoor side surface that is in contact with the indoor side surface of the door-end side wall 21a and protrudes toward the indoor side, and the fitting part 42 is a handle on the indoor side of the door-side side wall 21a. It fits into the portion 211 and is screwed to the bottom surface of the hand-held portion 211. And the protrusion piece 43 which protrudes toward the left side is formed in the position close | similar to the indoor side of the left side surface of the main-body part 41, The indoor side surface and protrusion piece of the fitting part 42 of the left side surface of the main-body part 41 are formed. A portion between 43 is a mounting surface 44 of the net member 3. In addition, the indoor side end of the main body 41 extends to the indoor side from the protruding piece 43, and this extended portion is a door-end side cover closed by the fitting portion 42 of the door-end side mounting material 4. It functions as a substitute for the handle portion 211 of the bag 21a.

また、戸当側の、戸先側取付材４に対向する位置には、戸当側取付材５を取り付けてある。戸先側取付材４が外障子２ａの戸先側竪框２１ａの室内側面に取り付けてあるので、戸当側取付材５の取り付け位置は、戸先側竪框２１ａに対向するサッシ枠１の竪枠１１の戸当部９ａの、室内側に隣接する位置、すなわち竪枠１１の、内障子２ｂの戸尻側竪框２２ｂに対向する位置となる。戸当側取付材５は、後述のロック部品７により着脱自在に取り付けられるものとなっており、ここでは取り付けた状態を前提として説明する。戸当側取付材５は、戸先側取付材４と略同じ上下長さを有するものであり、断面略Ｈ字形で、２つの略コ字形の開口部がそれぞれ左右方向を向いている。右側の開口部の底面は網材３の取付面５１となっており、戸先側取付材４の取付面４４と、戸当側取付材５の取付面５１とが対向している。また、左側の開口部内には、ロック部品７が納められている。なお、開口部の側面の間隔は、戸先側取付材４の嵌合部４２の室内側面と突出片４３の間隔よりわずかに狭くなっており、図１（ａ）に示すように、外障子２ａを閉じた際には、戸当側取付材５の右側部分が戸先側取付材４の嵌合部４２の室内側面と突出片４３の間に納まる。これにより、戸先側取付材４の取付面４４と戸当側取付材５の取付面５１に挟まれた閉じた空間が形成され、この空間が網材３を納める収納部５２となる。ここで、嵌合部４２の室内側面と、突出片４３の室外側面には、樹脂製の滑り止め部材４５を取り付けてあり、嵌合部４２と突出片４３の間に納めた戸当側取付材５が外れにくいようになっている。   Moreover, the door stop side attachment material 5 is attached to the door stop side at a position facing the door tip side attachment member 4. Since the door-end side attachment material 4 is attached to the indoor side surface of the door-end side ridge 21a of the external shoji 2a, the attachment position of the door-hold side attachment material 5 is that of the sash frame 1 facing the door-end side ridge 21a. It is a position adjacent to the indoor side of the door holding portion 9a of the heel frame 11, that is, a position of the heel frame 11 that faces the door butt side ridge 22b of the inner limb 2b. The door-holding side attachment material 5 is detachably attached by a lock part 7 described later, and here, the attached state will be described on the assumption. The door-holding side attachment material 5 has substantially the same vertical length as the door-end side attachment material 4, has a substantially H-shaped cross section, and two substantially U-shaped openings respectively face in the left-right direction. The bottom surface of the opening on the right side is the attachment surface 51 of the net member 3, and the attachment surface 44 of the door-end side attachment member 4 and the attachment surface 51 of the door stop side attachment member 5 are opposed to each other. A lock component 7 is housed in the left opening. In addition, the space | interval of the side surface of an opening part is slightly narrower than the space | interval of the indoor side surface of the fitting part 42 of the door-end side attachment material 4, and the protrusion piece 43, and as shown in FIG. When 2a is closed, the right side portion of the door-holding side attachment material 5 fits between the indoor side surface of the fitting portion 42 of the door-end side attachment material 4 and the protruding piece 43. Thereby, a closed space is formed between the mounting surface 44 of the door-end side mounting material 4 and the mounting surface 51 of the door-holding side mounting material 5, and this space becomes the storage portion 52 in which the net member 3 is stored. Here, a non-slip member 45 made of resin is attached to the indoor side surface of the fitting portion 42 and the outdoor side surface of the protruding piece 43, and the door side mounting attached between the fitting portion 42 and the protruding piece 43 is provided. The material 5 is difficult to come off.

さらに、網材３は、図１に示すように上面視してジグザグ状で、左右方向に折り畳み自在となっている。網材３の右側端は、戸先側取付材４の取付面４４に面ファスナー３１によって着脱自在に取り付けてあり、網材３の左側端は、戸当側取付材５の取付面５１に面ファスナー３１によって着脱自在に取り付けてある。網材３は、この左右端の面ファスナー３１のみによって固定されており、従来の折り畳み式の網材のように撓み防止のためのワイヤーなどは有していない。そして、図４（ｂ）に示すように、網材３の上端部は、サッシ枠１の上枠１２に形成した内障子２ｂのガイド溝１２１ｂに納まっている。一方、網材３の下端部には、略三角形の切欠部３２を形成してあり、切欠部３２を、サッシ枠１の下枠１３に形成した内障子２ｂのガイドレール１３１ｂが挿通している。   Further, as shown in FIG. 1, the net member 3 is zigzag in a top view and can be folded in the left-right direction. The right end of the mesh member 3 is detachably attached to the attachment surface 44 of the door end side attachment member 4 by a surface fastener 31, and the left end of the mesh member 3 faces the attachment surface 51 of the door stop side attachment member 5. Removably attached by a fastener 31. The net member 3 is fixed only by the left and right hook-and-loop fasteners 31 and does not have a wire or the like for preventing bending unlike a conventional folding net member. Then, as shown in FIG. 4B, the upper end portion of the mesh material 3 is accommodated in the guide groove 121 b of the inner limb 2 b formed on the upper frame 12 of the sash frame 1. On the other hand, a substantially triangular notch 32 is formed at the lower end of the net 3, and the notch 32 is inserted through a guide rail 131 b of the inner limb 2 b formed on the lower frame 13 of the sash frame 1. .

また、ロック部品７は、図１及び図６に示すように、前述のとおり戸当側取付材５の左側の開口部内に納められており、上下動自在な軸部７１を有している。軸部７１の室内側端部は戸当側取付材５の室内側面を貫通しており、先端には室内側に露出する操作部７２を設けてある。また、軸部７１の、戸当側取付材５の開口部内に位置する部分に、左側に向けて突出する閉用フック７３を設けてある。さらに、軸部７１の室外側端部は戸当側取付材５の室外側面を貫通しており、先端には右側に向けて突出する開用フック７４を設けてある。軸部７１と、操作部７２、閉用フック７３及び開用フック７４は一体となっており、操作部７２を上下動させることで、閉用フック７３及び開用フック７４も同時に上下動する。なお、閉用フック７３は下向きの鉤状であり、開用フック７４は上向きの鉤状である。そして、サッシ枠１の竪枠１１の右側面の、閉用フック７３に対向する位置には、上向きの鉤状の係合フック７５を取り付けてある。係合フック７５は、金属平板を折り曲げて形成したもので、竪枠１１の右側面にネジ止めしてある。これにより、外障子２ａを閉鎖した状態で操作部７２を下げれば、閉用フック７３が係合フック７５に係合して、戸当側取付材５が竪枠１１に固定される。一方、戸先側取付材４の嵌合部４２の左側面の、開用フック７４に対向する位置には、開用フック７４の先端が挿入される孔を形成してある。これにより、戸当側取付材５が戸先側取付材４に当接した状態で操作部７２を上げれば、開用フック７４が戸先側取付材４の嵌合部４２の孔に係合して、戸当側取付材５が戸先側取付材４に固定される。   As shown in FIGS. 1 and 6, the lock component 7 is housed in the opening on the left side of the door-holding side attachment member 5 as described above, and has a shaft portion 71 that can move up and down. The indoor side end portion of the shaft portion 71 penetrates the indoor side surface of the door-holding side attachment member 5, and an operation portion 72 exposed to the indoor side is provided at the tip. Further, a closing hook 73 protruding toward the left side is provided at a portion of the shaft portion 71 located in the opening of the door-holding side attachment material 5. Furthermore, the outdoor side end part of the shaft part 71 penetrates the outdoor side surface of the door-holding side attachment member 5, and an opening hook 74 protruding toward the right side is provided at the tip. The shaft portion 71, the operation portion 72, the closing hook 73, and the opening hook 74 are integrated. By moving the operation portion 72 up and down, the closing hook 73 and the opening hook 74 also move up and down at the same time. The closing hook 73 has a downward hook shape, and the opening hook 74 has an upward hook shape. An upward hook-like engagement hook 75 is attached to the right side surface of the collar frame 11 of the sash frame 1 at a position facing the closing hook 73. The engagement hook 75 is formed by bending a metal flat plate, and is screwed to the right side surface of the collar frame 11. Thereby, if the operation part 72 is lowered in a state in which the external shoji 2a is closed, the closing hook 73 is engaged with the engaging hook 75, and the door-holding side attachment member 5 is fixed to the collar frame 11. On the other hand, a hole into which the tip of the opening hook 74 is inserted is formed on the left side surface of the fitting portion 42 of the door end side attachment member 4 at a position facing the opening hook 74. Thereby, if the operation part 72 is raised in a state in which the door-holding side attachment material 5 is in contact with the door-end side attachment member 4, the opening hook 74 is engaged with the hole of the fitting part 42 of the door-end side attachment member 4. Then, the door-holding side attachment material 5 is fixed to the door-end side attachment material 4.

次に、このサッシの動作について説明する。通常はロック部品７の操作部７２を下げて、戸当側取付材５をサッシ枠１の竪枠１１に固定した状態にしておく。外障子２ａを閉鎖した状態（図１（ａ）、図３（ａ））においては、網材３が、戸先側取付材４と戸当側取付材５によって形成された収納部５２に折り畳まれて納まっており、外部からは見えないようになっている。そして、外障子２ａを開けると、戸先側竪框２１ａとともに戸先側取付材４が右側へ移動し、網材３が伸張して開口部を塞ぐ（図１（ｂ）、図３（ｂ））。外障子２ａはストッパー６により開口幅が制限されているから、図５に示すように一部のみが開口した状態となり、その部分が網材３により塞がれる。また、外障子２ａを閉じると、戸先側竪框２１ａとともに戸先側取付材４が左側へ移動し、網材３が折り畳まれて収納部５２に納まる。この際、網材３の上端部は上枠１２に形成した内障子２ｂのガイド溝１２１ｂに納まっており、また下端部に形成した切欠部３２を下枠１３に形成した内障子２ｂのガイドレール１３１ｂが挿通しているので、網材３の室内外方向の動きは規制され、網材３は撓むことなくスムーズに伸張し、また折り畳まれる。一方、外障子２ａを閉鎖した状態で、ロック部品７の操作部７２を上げて、戸当側取付材５とサッシ枠１の竪枠１１の係合を解除し、戸当側取付材５を戸先側取付材４に固定した状態にすれば、網材３を使用せずに外障子２ａを開くことができる（図２、図３（ｃ））。この状態においても、網材３は戸先側取付材４と戸当側取付材５によって形成された収納部５２に折り畳まれて納まっており、外部からは見えないようになっている。そして、ストッパー６を押し込んで開口幅の制限を解除すれば、外障子２ａを全開にすることもできる。   Next, the operation of this sash will be described. Usually, the operation part 72 of the lock part 7 is lowered, and the door-holding side attachment material 5 is fixed to the flange frame 11 of the sash frame 1. In the state (FIG. 1 (a), FIG. 3 (a)) in which the external shoji 2a is closed, the net member 3 is folded into the storage portion 52 formed by the door-end side mounting member 4 and the door-holding side mounting member 5. It is stored and is not visible from the outside. Then, when the external shoji 2a is opened, the door-end side attachment material 4 moves to the right side together with the door-end side rod 21a, and the net member 3 extends to close the opening (FIGS. 1B and 3B). )). Since the opening width of the external shoji 2 a is limited by the stopper 6, only a part is opened as shown in FIG. 5, and the part is closed by the net member 3. Further, when the external shoji 2a is closed, the door-end side attachment material 4 moves to the left side together with the door-end side collar 21a, and the net member 3 is folded and stored in the storage portion 52. At this time, the upper end portion of the mesh member 3 is accommodated in the guide groove 121b of the inner limb 2b formed on the upper frame 12, and the guide rail of the inner limb 2b formed on the lower frame 13 with the notch 32 formed on the lower end portion. Since 131b is inserted, the movement of the mesh member 3 in the indoor / outdoor direction is restricted, and the mesh member 3 is smoothly stretched and folded without being bent. On the other hand, in a state where the external shoji 2a is closed, the operation portion 72 of the lock part 7 is raised to release the engagement between the door-holding side attachment member 5 and the collar frame 11 of the sash frame 1, and the door-holding side attachment member 5 is If it is made into the state fixed to the door-end side attachment material 4, the outer shoji 2a can be opened without using the net | network material 3 (FIG. 2, FIG.3 (c)). Even in this state, the net member 3 is folded and stored in the storage portion 52 formed by the door end side attachment member 4 and the door stop side attachment member 5 so that it cannot be seen from the outside. And if the stopper 6 is pushed in and the restriction | limiting of opening width | variety is cancelled | released, the external shoji 2a can also be fully opened.

このように構成したサッシによれば、外障子２ａの戸先側竪框２１ａに取り付けた戸先側取付材４と、戸先側竪框２１ａに対向する戸当部９ａに隣接して取り付けた戸当側取付材５の間に網材３を取り付けてあるので、外障子２ａを開けると網材３も連動して広がり、外障子２ａを閉めると網材３も連動して折り畳まれるため、操作が容易である。この際、戸先側取付材４は外障子２ａと一体になって動くので、戸先側取付材４が垂直方向から傾くことはなく、開口部が網材３によって確実に塞がれ隙間が生じない。また、ストッパー６により外障子２ａの開口幅が制限されていて網材３の幅が短いので、伸張及び折り畳みの際に網材３が撓むことはなく、撓み防止のワイヤーなどが不要となっており、またこのワイヤーを巻き取る装置なども不要となっている。よって、網材３には何らの付勢力も働いていないので、開いた外障子２ａが閉鎖方向に動くことはなく、開口幅の制限の範囲内の任意の位置で停止できる。そして、巻き取りのための機構などがない簡易な構成であるから、全体がコンパクトで（本実施形態では全体がサッシ枠１の見込幅内に納まっている）、費用が抑えられ、ワイヤーを巻き取る装置などの故障のおそれもない。また、網材３の上端部は上枠１２に形成した内障子２ｂのガイド溝１２１ｂに納まっており、また下端部に形成した切欠部３２を下枠１３に形成した内障子２ｂのガイドレール１３１ｂが挿通しているので、網材３の上下端部が左右方向にガイドされてスムーズに伸張し、また折り畳まれるとともに、網材３の上下端部と上枠１２又は下枠１３との間の隙間が小さくなって、虫が侵入しにくくなっている。さらに、網材３は戸先側取付材４と戸当側取付材５に対して面ファスナーにより着脱自在に取り付けてあるから、取り替えが容易でメンテナンス性がよい。また、網材３を使用した状態で開口幅の制限を解除して外障子２ａを開きすぎた場合には、網材３が容易に戸先側取付材４又は戸当側取付材５から外れるので、網材３を損傷することもない。さらに、戸先側取付材４を外障子２ａの戸先側竪框２１ａに取り付け、戸当側取付材５をサッシ枠１の竪枠１１に取り付けるだけでよいため、既存のサッシへの後付けも容易であり、サッシ枠１の取り替えなども必要ないので、費用が抑えられる。   According to the sash comprised in this way, it attached adjacent to the door stop part 9a which opposes the door-end side attachment material 4 attached to the door-end side fence 21a of the shoji 2a, and the door-end side fence 21a. Since the mesh member 3 is attached between the door-holding side attachment members 5, the mesh member 3 spreads in conjunction with the opening of the outer shoji 2a, and the mesh member 3 is also folded in conjunction with the closing of the outer guard member 2a. Easy to operate. At this time, since the door-end side attachment material 4 moves integrally with the shingles 2a, the door-end side attachment material 4 is not inclined from the vertical direction, and the opening is reliably closed by the netting material 3 and a gap is formed. Does not occur. In addition, since the opening width of the outer obstacle 2a is limited by the stopper 6 and the width of the mesh member 3 is short, the mesh member 3 does not bend at the time of expansion and folding, and a wire for preventing bending is unnecessary. In addition, a device for winding this wire is not required. Therefore, since no urging force is applied to the net member 3, the open outer obstacle 2a does not move in the closing direction, and can be stopped at any position within the range of the opening width limit. And since it is a simple structure without a winding mechanism, etc., the whole is compact (in the present embodiment, the whole is within the expected width of the sash frame 1), the cost is reduced, and the wire is wound. There is no risk of failure of the equipment to be removed. Further, the upper end portion of the mesh member 3 is accommodated in the guide groove 121b of the inner limb 2b formed in the upper frame 12, and the guide rail 131b of the inner limb 2b in which the notch portion 32 formed in the lower end portion is formed in the lower frame 13. Since the upper and lower ends of the mesh material 3 are guided in the left-right direction, the mesh material 3 is smoothly stretched and folded, and between the upper and lower ends of the mesh material 3 and the upper frame 12 or the lower frame 13. The gap is getting smaller, making it harder for insects to enter. Further, since the net member 3 is detachably attached to the door end side attachment member 4 and the door stop side attachment member 5 by means of a hook-and-loop fastener, it can be easily replaced and has good maintainability. Moreover, when the restriction | limiting of opening width | variety is cancelled | released in the state which used the net | network material 3, and the external shoji 2a is opened too much, the net | network material 3 will remove | deviate easily from the door-end side attachment material 4 or the door stop side attachment material 5. Therefore, the net material 3 is not damaged. Furthermore, since it is only necessary to attach the door-end side attachment material 4 to the door-end side cage 21a of the external shoji 2a and attach the door-hold side attachment material 5 to the cage frame 11 of the sash frame 1, the retrofit to the existing sash is also possible. Since it is easy and replacement of the sash frame 1 is not necessary, the cost can be reduced.

次に、本発明のサッシの第二実施形態を示す。第一実施形態と異なるのは、網材３を内障子２ｂの室内側に設けてある点であり、サッシ枠１、外障子２ａ及び内障子２ｂや外障子２ａに設けたストッパー６は第一実施形態と同じである。また、戸先側取付材４及び戸当側取付材５も第一実施形態と同じものであるが、第一実施形態とは左右に反転した向きとなる。より詳しくは、図７〜図１０に示すように、内障子２ｂの戸先側竪框２１ｂの室内側面に、戸先側取付材４を取り付けてある。内障子２ｂは、ガラスパネル２５ｂを保持するパネル保持部分が室内側に持ち出しているが、戸先側取付材４はその持出部分の戸先側に位置しており、嵌合部４２が戸先側竪框２１ｂの室内側の手掛部２１１に嵌合していて、手掛部２１１の底面にネジ止めしてある。そして、本体部４１の右側面に網材３の取付面４４がある。   Next, a second embodiment of the sash of the present invention will be shown. The difference from the first embodiment is that the net member 3 is provided on the indoor side of the inner impeller 2b, and the sash frame 1, the outer imperial child 2a, the inner imperial child 2b, and the stopper 6 provided on the outer imperial child 2a are the first. This is the same as the embodiment. Moreover, although the door end side attachment material 4 and the door stop side attachment material 5 are the same as 1st embodiment, it becomes the direction reversed right and left with 1st embodiment. More specifically, as shown in FIGS. 7 to 10, the door-end side attachment material 4 is attached to the indoor side surface of the door-end side ridge 21 b of the inner limb 2 b. Although the panel holding part which holds the glass panel 25b is taken out indoors, the door-end side attachment material 4 is located in the door-end side of the carrying-out part, and the fitting part 42 is the door. The front side hook 21b is fitted to the indoor side handle 211, and is screwed to the bottom surface of the handle 211. The attachment surface 44 of the net member 3 is provided on the right side surface of the main body 41.

また、戸当側の、戸先側取付材４に対向する位置には、戸当側取付材５を取り付けてある。戸先側取付材４が内障子２ｂの戸先側竪框２１ｂの室内側面に取り付けてあるので、戸当側取付材５の取り付け位置は、戸先側竪框２１ｂに対向するサッシ枠１の竪枠１１の戸当部９ｂの、室内側に隣接する位置、すなわち竪枠１１の室内側に延びるアングル片１１１と、アングル片１１１に連続して設けてある額縁８に跨った位置となる。戸当側取付材５は、左側の開口部の底面が網材３の取付面５１となっており、戸先側取付材４の取付面４４と、戸当側取付材５の取付面５１とが対向していて、両者の間に収納部５２が形成される。また、右側の開口部内には、第一実施形態と同じロック部品７が納められている。   Moreover, the door stop side attachment material 5 is attached to the door stop side at a position facing the door tip side attachment member 4. Since the door-end side attachment material 4 is attached to the indoor side surface of the door-end side ridge 21b of the inner shoji 2b, the attachment position of the door-hold side attachment material 5 is that of the sash frame 1 facing the door-end side ridge 21b. This is a position adjacent to the indoor side of the door holding portion 9 b of the frame frame 11, that is, a position straddling the angle piece 111 extending to the indoor side of the frame frame 11 and the frame 8 provided continuously to the angle piece 111. The door-holding-side attachment material 5 has a bottom surface of the opening on the left side as an attachment surface 51 of the net member 3, an attachment surface 44 of the door-end side attachment material 4, and an attachment surface 51 of the door-holding side attachment material 5. Are opposite to each other, and a storage portion 52 is formed between the two. Further, the same lock component 7 as that in the first embodiment is accommodated in the opening on the right side.

さらに、網材３も第一実施形態と同様のものであり、戸先側取付材４の取付面４４と戸当側取付材５の取付面５１に、それぞれ面ファスナー３１によって着脱自在に取り付けてある。ただし、図１０（ｂ）に示すように、下端部に切欠部は形成されていない。網材３の上下端に対向する面には、それぞれ上枠１２又は下枠１３のアングル片１２２，１３２と額縁８に跨って受板３３を取り付けてあり、網材３の上下端が受板３３にわずかな隙間を開けて対向した状態となっている。   Further, the net member 3 is the same as that of the first embodiment, and is detachably attached to the attachment surface 44 of the door end side attachment member 4 and the attachment surface 51 of the door stop side attachment member 5 by the hook-and-loop fasteners 31 respectively. is there. However, as shown in FIG. 10B, the notch is not formed at the lower end. The receiving plate 33 is attached to the surface facing the upper and lower ends of the net member 3 so as to straddle the angle pieces 122 and 132 of the upper frame 12 or the lower frame 13 and the frame 8, respectively. 33 is in a state of facing a small gap.

この第二実施形態のサッシも、第一実施形態と同様に動作するものであり、ロック部品７の操作部７２を下げて戸当側取付材５をサッシ枠１の竪枠１１に固定した状態にしておき、内障子２ｂを閉鎖した状態（図７（ａ）、図９（ａ））から内障子２ｂを開けると、戸先側竪框２１ｂとともに戸先側取付材４が左側へ移動し、網材３が伸張して開口部を塞ぐ（図７（ｂ）、図９（ｂ））。また、内障子２ｂを閉じると、戸先側竪框２１ｂとともに戸先側取付材４が右側へ移動し、網材３が折り畳まれて収納部５２に納まる。一方、内障子２ｂを閉鎖した状態で、ロック部品７の操作部７２を上げて戸当側取付材５とサッシ枠１の竪枠１１の係合を解除し、戸当側取付材５を戸先側取付材４に固定した状態にすれば、網材３を使用せずに内障子２ｂを開くことができる（図８、図９（ｃ））。   The sash according to the second embodiment also operates in the same manner as the first embodiment, and the operation part 72 of the lock part 7 is lowered and the door holding side attachment material 5 is fixed to the flange frame 11 of the sash frame 1. Then, when the pouch 2b is opened from the state in which the pouch 2b is closed (FIG. 7 (a), FIG. 9 (a)), the door-end side attachment material 4 moves to the left side together with the door-end side hook 21b. Then, the net member 3 extends to close the opening (FIGS. 7B and 9B). Further, when the inner shoji 2b is closed, the door-end side attachment material 4 moves to the right side together with the door-end side collar 21b, and the net member 3 is folded and stored in the storage portion 52. On the other hand, in a state in which the inner impeller 2b is closed, the operation portion 72 of the lock component 7 is raised to release the engagement between the door-holding side attachment member 5 and the collar frame 11 of the sash frame 1, and the door-holding side attachment member 5 is moved to the door. If it fixes to the front side attachment material 4, the inner impeller 2b can be opened without using the net | network material 3 (FIG. 8, FIG.9 (c)).

このように構成した第二実施形態のサッシにおいても、内障子２ｂを開けると網材３も連動して広がり、内障子２ｂを閉めると網材３も連動して折り畳まれるため、操作が容易であり、その他、第一実施形態と同様の作用効果を奏するものである。ただし、網材３の上下端が上下枠のガイド溝又はガイドレールにガイドされていないので、その点を除く。また、サッシ枠１からは室内側に突出しているが、全体はコンパクトである。   Even in the sash of the second embodiment configured as described above, the net member 3 spreads in conjunction with the opening of the inner impeller 2b, and the net member 3 is also folded in conjunction with closing the inner impeller 2b, so that the operation is easy. There are other effects similar to those of the first embodiment. However, since the upper and lower ends of the net 3 are not guided by the guide grooves or guide rails of the upper and lower frames, this point is excluded. Moreover, although it protrudes from the sash frame 1 to the indoor side, the whole is compact.

次に、本発明のサッシの第三実施形態を示す。第一実施形態と異なるのは、網材３を内障子２ｂの室外側に設けてある点であり、サッシ枠１、外障子２ａ及び内障子２ｂや外障子２ａに設けたストッパー６は第一実施形態と同じである。また、戸先側取付材４及び戸当側取付材５も第一実施形態と同じものであるが、第一実施形態とは室内外及び左右に反転した向きとなる。より詳しくは、図１１〜図１４に示すように、内障子２ｂの戸先側竪框２１ｂの室外側面に、戸先側取付材４を取り付けてあり、嵌合部４２が戸先側竪框２１ｂの室外側の手掛部２１１に嵌合していて、手掛部２１１の底面にネジ止めしてある。そして、本体部４１の右側面に網材３の取付面４４がある。   Next, a third embodiment of the sash of the present invention will be shown. The difference from the first embodiment is that the net member 3 is provided outside the inner door 2b. The sash frame 1, the outer door 2a, the inner door 2b, and the stopper 6 provided on the outer door 2a are the first ones. This is the same as the embodiment. Moreover, although the door end side attachment material 4 and the door stop side attachment material 5 are also the same as 1st embodiment, it becomes the direction reversed inside and outside and left and right with 1st embodiment. More specifically, as shown in FIGS. 11 to 14, the door-end side attachment material 4 is attached to the outdoor side surface of the door-end side ridge 21 b of the inner shoji 2 b, and the fitting portion 42 is the door-end side ridge. It fits into the outdoor handle 21b of 21b and is screwed to the bottom of the handle 211. The attachment surface 44 of the net member 3 is provided on the right side surface of the main body 41.

また、戸当側の、戸先側取付材４に対向する位置には、戸当側取付材５を取り付けてある。戸先側取付材４が内障子２ｂの戸先側竪框２１ｂの室外側面に取り付けてあるので、戸当側取付材５の取り付け位置は、戸先側竪框２１ｂに対向するサッシ枠１の竪枠１１の戸当部９ｂの、室外側に隣接する位置、すなわち竪枠１１の、外障子２ａの戸尻側竪框２２ａに対向する位置となる。戸当側取付材５は、左側の開口部の底面が網材３の取付面５１となっており、戸先側取付材４の取付面４４と、戸当側取付材５の取付面５１とが対向していて、両者の間に収納部５２が形成される。また、右側の開口部内には、第一実施形態と同じロック部品７が納められている。   Moreover, the door stop side attachment material 5 is attached to the door stop side at a position facing the door tip side attachment member 4. Since the door-end side attachment material 4 is attached to the outdoor side surface of the door-end side ridge 21b of the inner shoji 2b, the attachment position of the door-hold side attachment material 5 is that of the sash frame 1 facing the door-end side ridge 21b. It is a position adjacent to the outdoor side of the door holding portion 9b of the heel frame 11, that is, a position of the heel frame 11 that faces the door butt side ridge 22a of the external shoji 2a. The door-holding-side attachment material 5 has a bottom surface of the opening on the left side as an attachment surface 51 of the net member 3, an attachment surface 44 of the door-end side attachment material 4, and an attachment surface 51 of the door-holding side attachment material 5. Are opposite to each other, and a storage portion 52 is formed between the two. Further, the same lock component 7 as that in the first embodiment is accommodated in the opening on the right side.

さらに、網材３も第一実施形態と同様のものであり、戸先側取付材４の取付面４４と戸当側取付材５の取付面５１に、それぞれ面ファスナー３１によって着脱自在に取り付けてある。ただし、図１４（ｂ）に示すように、上端部と下端部の両方に略三角形の切欠部３２を形成してあり、上側の切欠部３２を、サッシ枠１の上枠１２に形成した外障子２ａのガイドレール１２１ａが挿通しており、下側の切欠部３２を、サッシ枠１の下枠１３に形成した外障子２ａのガイドレール１３１ａが挿通している。   Further, the net member 3 is the same as that of the first embodiment, and is detachably attached to the attachment surface 44 of the door end side attachment member 4 and the attachment surface 51 of the door stop side attachment member 5 by the hook-and-loop fasteners 31 respectively. is there. However, as shown in FIG. 14B, a substantially triangular notch 32 is formed at both the upper end and the lower end, and the upper notch 32 is formed on the upper frame 12 of the sash frame 1. The guide rail 121a of the shoji 2a is inserted, and the guide rail 131a of the shoji 2a formed on the lower frame 13 of the sash frame 1 is inserted through the lower notch 32.

この第三実施形態のサッシも、第一実施形態と同様に動作するものであり、ロック部品７の操作部７２を下げて戸当側取付材５をサッシ枠１の竪枠１１に固定した状態にしておき、内障子２ｂを閉鎖した状態（図１１（ａ）、図１３（ａ））から内障子２ｂを開けると、戸先側竪框２１ｂとともに戸先側取付材４が左側へ移動し、網材３が伸張して開口部を塞ぐ（図１１（ｂ）、図１３（ｂ））。また、内障子２ｂを閉じると、戸先側竪框２１ｂとともに戸先側取付材４が右側へ移動し、網材３が折り畳まれて収納部５２に納まる。一方、内障子２ｂを閉鎖した状態で、ロック部品７の操作部７２を上げて戸当側取付材５とサッシ枠１の竪枠１１の係合を解除し、戸当側取付材５を戸先側取付材４に固定した状態にすれば、網材３を使用せずに内障子２ｂを開くことができる（図１２、図１３（ｃ））。   The sash according to the third embodiment also operates in the same manner as the first embodiment, and the operation part 72 of the lock part 7 is lowered and the door holding side attachment material 5 is fixed to the flange frame 11 of the sash frame 1. Then, when the pouch 2b is opened from the state where the pouch 2b is closed (FIG. 11 (a), FIG. 13 (a)), the door-side attachment material 4 moves to the left side together with the door-side ridge 21b. Then, the net member 3 expands to close the opening (FIGS. 11B and 13B). Further, when the inner shoji 2b is closed, the door-end side attachment material 4 moves to the right side together with the door-end side collar 21b, and the net member 3 is folded and stored in the storage portion 52. On the other hand, in a state in which the inner impeller 2b is closed, the operation portion 72 of the lock component 7 is raised to release the engagement between the door-holding side attachment member 5 and the collar frame 11 of the sash frame 1, and the door-holding side attachment member 5 is moved to the door. If it is made the state fixed to the front side attachment material 4, the inner impeller 2b can be opened without using the net | network material 3 (FIG. 12, FIG. 13 (c)).

このように構成した第三実施形態のサッシにおいても、内障子２ｂを開けると網材３も連動して広がり、内障子２ｂを閉めると網材３も連動して折り畳まれるため、操作が容易であり、その他、第一実施形態と同様の作用効果を奏するものである。なお、網材３の上端部については、第一実施形態のようにガイド溝１２１ｂにガイドされていても、第三実施形態のようにガイドレール１２１ａにガイドされていても、同様の作用効果を奏する。   Even in the sash of the third embodiment configured as described above, the net member 3 spreads in conjunction with the opening of the inner impeller 2b, and the net member 3 is also folded in conjunction with the closing of the impeller 2b, so that the operation is easy. There are other effects similar to those of the first embodiment. It should be noted that the upper end portion of the net member 3 has the same function and effect regardless of whether it is guided by the guide groove 121b as in the first embodiment or guided by the guide rail 121a as in the third embodiment. Play.

次に、本発明のサッシの第四実施形態を示す。第一実施形態と異なるのは、図１５に示すように、網材３を外障子２ａの室内側と内障子２ｂの室内側の両方に設けてある点であり、サッシ枠１、外障子２ａ及び内障子２ｂや外障子２ａに設けたストッパー６は第一実施形態と同じである。そして、外障子２ａの室内側に設けた網材３部分については第一実施形態と同じであり、内障子２ｂの室内側に設けた網材３部分については第二実施形態と同じである。このように構成した第四実施形態のサッシにおいては、第一実施形態及び第二実施形態と同様の作用効果を奏するものであり、また、サッシの両側に開口部を設けることで、より効率のよい換気が可能である。なお、ストッパー６の位置が第一実施形態と同じであるから、左右の外障子２ａと内障子２ｂの開口幅の合計が、第一実施形態の外障子２ａの開口幅と等しくなる。   Next, 4th embodiment of the sash of this invention is shown. As shown in FIG. 15, the first embodiment is different from the first embodiment in that the mesh member 3 is provided on both the indoor side of the external obstacle 2a and the indoor side of the internal obstacle 2b, and the sash frame 1 and the external obstacle 2a. And the stopper 6 provided in the inner imperial child 2b and the outer imperial child 2a is the same as 1st embodiment. And the net | network material 3 part provided in the room inner side of the external shoji 2a is the same as 1st embodiment, and the net | network material 3 part provided in the room inner side of the inner shoji 2b is the same as 2nd embodiment. In the sash of the fourth embodiment configured in this manner, the same effects as the first embodiment and the second embodiment are achieved, and more efficient by providing openings on both sides of the sash. Good ventilation is possible.
