Description

本発明は、換気経路を設けた戸に関する。 The present invention relates to a door provided with a ventilation path.

浴室と脱衣室を仕切る戸には、換気機能が求められる。従来、特許文献１の発明のように、障子を納める枠体の上枠に換気経路を形成し、換気経路内に開閉弁を設けたものが知られている。この開閉弁は回動自在であり、通常時は垂れ下がった状態で換気経路を閉鎖している。そして浴室の換気扇を駆動すると、浴室内が負圧となることで開閉弁は浴室側に回動し、換気経路が開放されて、浴室の換気が可能となる。 The door that separates the bathroom from the dressing room must have a ventilation function. Conventionally, as in the invention of Patent Document 1, a ventilation path is formed in an upper frame of a frame body that houses a shoji, and an on-off valve is provided in the ventilation path. This on-off valve is pivotable and normally closes the ventilation path in a suspended state. When the bathroom fan is driven, the inside of the bathroom becomes negative pressure, so that the on-off valve rotates to the bathroom side, the ventilation path is opened, and the bathroom can be ventilated.

しかしながら、特許文献１の発明においては、浴室から開閉弁に至る換気経路内に水や水蒸気の浸入を妨げるような構造はなく、それらが容易に開閉弁まで到達してしまい、さらに開閉弁が脱衣室側に位置しているので、水や水蒸気が開閉弁を超えるとすぐに脱衣室側に入り込んでしまう点が問題であった。また、上枠が、換気経路の上側の第一上枠と、換気経路の下側の第二上枠に分かれており、障子を支持する第二上枠が天井には接しておらず、左右の縦枠のみに固定されるものであるから、強度が低い点も問題であった。 However, in the invention of Patent Document 1, there is no structure that prevents water and water vapor from entering the ventilation path from the bathroom to the on-off valve, and they easily reach the on-off valve, and the on-off valve is undressed. Since it is located on the room side, it has been a problem that water or water vapor enters the dressing room as soon as it exceeds the on-off valve. In addition, the upper frame is divided into a first upper frame on the upper side of the ventilation path and a second upper frame on the lower side of the ventilation path, and the second upper frame supporting the shoji is not in contact with the ceiling. Since it is fixed only to the vertical frame, the low strength is also a problem.

本発明は、上記事情を鑑みたものであり、換気経路を水や水蒸気が通過することなく、かつ換気経路部分の強度が高い戸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 thereof is to provide a door in which water and water vapor do not pass through the ventilation path and the strength of the ventilation path portion is high.

本発明は、枠体と、枠体に開閉自在に納めた障子と、開閉弁と、通気口カバーと、押圧部材とを備え、枠体の横枠又は障子の横框は、上側部分と、下側部分と、これらを繋ぐ連結壁とを有し、連結壁には、見込方向に貫通する通気口を設けてあって、上側部分と下側部分の間に換気経路を形成してあり、開閉弁は、換気経路の一方側の空間寄りに連結壁から離隔して設けてあり、自重で閉じ方向に回動自在で、換気経路の一方側の空間が負圧になると回動して開放状態となるものであり、通気口カバーは、通気口の周縁部を覆うものであり、押圧部材は、通気口カバーに取り付けてあって、開閉弁を一方側に押圧して常に開放状態とする押圧状態と、開閉弁から離隔する非押圧状態とに切替可能なものであり、押圧状態と非押圧状態のそれぞれにおいて移動を規制するストッパを有することを特徴とする。なお、ストッパは、押圧部材や通気口カバーなど、本発明を構成する何れの要素に設けてあってもよい。 The present invention comprises a frame, a shoji that can be freely opened and closed in the frame, an on-off valve, a vent cover, and a pressing member, and the horizontal frame of the frame or the reed of the shoji has an upper portion, It has a lower part and a connecting wall connecting them, and the connecting wall is provided with a vent hole penetrating in the expected direction, and a ventilation path is formed between the upper part and the lower part, The on-off valve is provided near the space on one side of the ventilation path and separated from the connecting wall, and is rotatable in the closing direction by its own weight, and rotates and opens when the space on one side of the ventilation path becomes negative pressure. The vent cover covers the peripheral edge of the vent, and the pressing member is attached to the vent cover and presses the open / close valve to one side so that it is always open. It can be switched between a pressed state and a non-pressed state separated from the on-off valve. It characterized by having a stopper for restricting the movement in the. The stopper may be provided on any element that constitutes the present invention, such as a pressing member or a vent cover.

本発明によれば、換気経路の一方側の空間（浴室）寄りに連結壁から離隔して開閉弁を設けてあって、また換気経路の途中に設けた連結壁が水や水蒸気の浸入を妨げることにより、水や水蒸気が他方側の空間（脱衣室）に入り込まない。また、連結壁により換気経路の上下の上側部分と下側部分とが一体になっているので、強度が高い。さらに、通気口カバーが通気口の小口の色目の違いを覆い隠すので意匠性が良好であり、また、通気口カバーが清掃などの際に通気口の小口のエッジで手を切る怪我を防ぐので安全性も高い。そして、通気口カバーに押圧部材を取り付けるので、横枠又は横框に加工を施す必要がない。 According to the present invention, the on-off valve is provided apart from the connecting wall near the space (bathroom) on one side of the ventilation path, and the connecting wall provided in the middle of the ventilation path prevents water and water vapor from entering. Therefore, water and water vapor do not enter the space on the other side (dressing room). Moreover, since the upper and lower upper and lower portions of the ventilation path are integrated by the connecting wall, the strength is high. In addition, the vent cover covers the difference in the color of the vent's mouth, so it has good design, and the vent cover prevents injuries that cut the hand at the edge of the vent's mouth when cleaning. High safety. And since a press member is attached to a vent hole cover, it is not necessary to process a horizontal frame or a reed.

Moreover, the bathroom side end of the trunk | drum 32 is a taper shape by planar view. Further, as shown in FIG. 4 (b), the body portion 32 has a lower height at the bathroom side end portion, and in particular, an inclined portion 37 inclined downward toward the bathroom side is formed at the tip portion. is there.

そして、この押圧部材３を取付用通気口カバー２ｂのホルダ２４に挿入してある。押圧部材３の胴部３２の外寸とホルダ２４の内寸は略同じであるが、胴部３２の浴室側端は先細形状となっているので、挿入しやすくなっている。挿入の際、ホルダ２４内の突条２５が胴部３２の左右の側壁に引っ掛かるが、側壁の内側が中空なので、側壁は内側に撓んで挿入が可能となり、突条２５は凹部３５に納まる。押圧部材３は突条２５が凹部３５に納まる範囲で見込方向に移動可能であり、脱衣室側から把持部３３を持って操作する。押圧部材３を最も浴室側まで押し込むと図７（ａ）の状態となり、突条２５が脱衣室側のストッパ３１ａと中間突起３６の間に嵌まっていて、押圧部材３の見込方向位置が固定されている。この状態の押圧部材３は、図１において実線で表されていて、押圧部材３の浴室側端が開閉弁１を浴室側に押圧して常に換気経路Ｃを開放状態としており、この状態を押圧状態とよぶ。この際、押圧部材３の浴室側端部の高さが低くなっていることで、開閉弁１の軸部１１を回避しており、また、押圧部材３の浴室側端の傾斜部３７が、開放状態の開閉弁１の面部１２と略平行になって広い面で当接するので、開閉弁１を確実に保持できる。なお、押圧状態においては、ホルダ２４の突条２５の脱衣室側端が、押圧部材３の脱衣室側のストッパ３１ａに係合しており、ストッパ３１ａは直角形状なので突条２５がストッパ３１ａを乗り越えることはできないから、それ以上押圧部材３が浴室側に移動することは規制されている。一方、中間突起３６は三角形なので、押圧部材３の胴部３２の側壁が撓むことで（内側が中空なので撓みやすい）突条２５が中間突起３６を乗り越えることができるから、把持部３３を持って力を加えれば押圧部材３を脱衣室側に引くことができる。また、押圧部材３を最も脱衣室側まで引くと図７（ｂ）の状態となり、突条２５が浴室側のストッパ３１ｂと中間突起３６の間に嵌まっていて、押圧部材３の見込方向位置が固定されている。この状態の押圧部材３は、図１において二点鎖線で表されていて、押圧部材３の浴室側端が開閉弁１から離隔して開閉弁１は回動自在となっており（図１（二点鎖線）では自重で垂れ下がって換気経路Ｃを閉鎖している）、この状態を非押圧状態とよぶ。なお、非押圧状態においては、ホルダ２４の突条２５の浴室側端が、押圧部材３の浴室側のストッパ３１ｂに係合しており、ストッパ３１ｂは直角形状なので突条２５がストッパ３１ｂを乗り越えることはできないから、それ以上押圧部材３が脱衣室側に移動することは規制されている。一方、中間突起３６は三角形なので、押圧部材３の胴部３２の側壁が撓むことで（内側が中空なので撓みやすい）突条２５が中間突起３６を乗り越えることができるから、把持部３３を持って力を加えれば押圧部材３を浴室側に押すことができる。なお、突条２５は、見込方向両端部の突出幅が大きく、見込方向中間部の突出幅が小さいので、突条２５の見込方向両端部が中間突起３６を乗り越えて押圧状態と非押圧状態の中間状態になった際に、押圧部材３を見込方向に動かしやすくなっている。このように、押圧部材３を押し引きすることで押圧状態と非押圧状態を切替可能であり、押圧状態では開閉弁１が常に換気経路Ｃを開放した状態となる。一方、非押圧状態では開閉弁１が回動自在であって、通常は自重で垂れ下がって換気経路Ｃを閉鎖した状態となり、浴室が負圧になると回動して換気経路Ｃを開放した状態となる。 The pressing member 3 is inserted into the holder 24 of the mounting vent cover 2b. Although the outer dimension of the trunk | drum 32 of the press member 3 and the inner dimension of the holder 24 are substantially the same, since the bathroom side end of the trunk | drum 32 is a taper shape, it is easy to insert. At the time of insertion, the ridge 25 in the holder 24 is caught on the left and right side walls of the body portion 32, but since the inside of the side wall is hollow, the side wall can be bent and inserted, and the ridge 25 is stored in the recess 35. The pressing member 3 can move in the expected direction as long as the ridges 25 are accommodated in the recesses 35, and is operated by holding the grip portion 33 from the dressing room side. When the pressing member 3 is pushed all the way to the bathroom side, the state shown in FIG. 7A is obtained, and the protrusion 25 is fitted between the stopper 31a on the dressing room side and the intermediate protrusion 36, and the position in the expected direction of the pressing member 3 is fixed. Has been. The pressing member 3 in this state is represented by a solid line in FIG. 1, and the bathroom side end of the pressing member 3 presses the on-off valve 1 toward the bathroom side to always open the ventilation path C, and this state is pressed. It is called a state. At this time, because the height of the bathroom-side end of the pressing member 3 is low, the shaft portion 11 of the on-off valve 1 is avoided, and the inclined portion 37 at the bathroom-side end of the pressing member 3 is Since the opening / closing valve 1 is substantially parallel to the surface portion 12 and abuts on a wide surface, the opening / closing valve 1 can be reliably held. In the pressed state, the undressing chamber side end of the protrusion 25 of the holder 24 is engaged with the stopper 31a on the undressing chamber side of the pressing member 3, and the stopper 31a has a right-angled shape. Since it cannot get over, it is restricted that the press member 3 moves to the bathroom side any more. On the other hand, since the intermediate protrusion 36 has a triangular shape, the protrusion 25 can get over the intermediate protrusion 36 by bending the side wall of the body portion 32 of the pressing member 3 (because the inside is hollow). If a force is applied, the pressing member 3 can be pulled toward the dressing room. Moreover, when the pressing member 3 is pulled to the dressing room side most, it will be in the state of FIG.7 (b), and the protrusion 25 will fit between the stopper 31b and the intermediate protrusion 36 of the bathroom side, and the expected direction position of the pressing member 3 Is fixed. The pressing member 3 in this state is represented by a two-dot chain line in FIG. 1, and the end of the pressing member 3 on the bathroom side is separated from the opening / closing valve 1 so that the opening / closing valve 1 is rotatable (FIG. 1 ( In the alternate long and two short dashes line), the ventilation path C is hung down by its own weight), and this state is called a non-pressed state. In the non-pressed state, the bathroom side end of the ridge 25 of the holder 24 is engaged with the stopper 31b on the bathroom side of the pressing member 3, and since the stopper 31b has a right angle, the ridge 25 gets over the stopper 31b. Since it cannot be performed, it is restricted that the pressing member 3 moves to the dressing room side any more. On the other hand, since the intermediate protrusion 36 has a triangular shape, the protrusion 25 can get over the intermediate protrusion 36 by bending the side wall of the body portion 32 of the pressing member 3 (because the inside is hollow). If the force is applied, the pressing member 3 can be pushed to the bathroom side. In addition, since the protrusion 25 has a large protrusion width at both ends in the prospective direction and a small protrusion width at the intermediate portion in the expectation direction, the both ends in the expectation direction of the protrusion 25 get over the intermediate protrusion 36 and are in a pressed state and a non-pressed state. When the intermediate state is reached, the pressing member 3 is easily moved in the expected direction. In this way, it is possible to switch between the pressed state and the non-pressed state by pushing and pulling the pressing member 3, and the open / close valve 1 always opens the ventilation path C in the pressed state. On the other hand, in the non-pressed state, the opening / closing valve 1 is freely rotatable, and normally it is hung down by its own weight to close the ventilation path C, and when the bathroom is under negative pressure, it is rotated to open the ventilation path C. Become.

このように構成した戸の第一実施形態によれば、換気経路Ｃの浴室寄りに連結壁７から離隔して開閉弁１を設けてあって、開閉弁１から脱衣室まで距離があるので、浴室側から流入する水や水蒸気が開閉弁１を通過しても脱衣室側まで届きにくい。また、換気経路Ｃの途中に設けた連結壁７が水や水蒸気の浸入を妨げる。特に、通気口７１の下側に下側部分６の上側面６１から立ち上がる連結壁７の壁面が存在しているので、確実に止水される。よって、水や水蒸気が脱衣室に入り込まない。また、連結壁７により換気経路Ｃの上下の上側部分５と下側部分６とが一体になっているので、強度が高い。さらに、通気口カバー２ａ，２ｂが通気口７１の小口の色目の違い（金属の切断面なので周囲と色目が異なる）を覆い隠すので意匠性が良好であり、また、通気口カバー２ａ，２ｂが清掃などの際に通気口７１の小口のエッジで手を切る怪我を防ぐので安全性も高い。そして、取付用通気口カバー２ｂに押圧部材３を取り付けるので、上枠１０ａに加工を施す必要がない。また、開閉弁１は左右に長い単一部材のものであるから、左右方向のどの位置で押圧部材３により押圧してもよいので、任意の通気口７１に取付用通気口カバー２ｂ及び押圧部材３を取り付けて適宜操作位置を変更することができ、左右勝手の違いなどにも容易に対応できる。さらに、押圧部材３によって開閉弁１を強制的に開放状態に保持することができるので、２４時間換気にも対応可能である。そして、この押圧部材３はストッパ３１ａ，３１ｂにより所定範囲以上動くことはなく、開閉弁１や機構の破損を防いでいる。また、開閉弁１が浴室側に位置しており、押圧部材３を戸の見込中程に設けることができるので、押圧部材３の脱衣室側への露出が少なく意匠性が良好であるとともに、押圧部材３自体は見えにくいので意匠性を考慮する必要性が小さく、設計の自由度が高い。 According to the first embodiment of the door configured as described above, the opening / closing valve 1 is provided at a distance from the connecting wall 7 near the bathroom of the ventilation path C, and there is a distance from the opening / closing valve 1 to the dressing room. Even if water or steam flowing in from the bathroom side passes through the on-off valve 1, it is difficult to reach the dressing room side. Moreover, the connection wall 7 provided in the middle of the ventilation path C prevents water and water vapor from entering. In particular, since the wall surface of the connecting wall 7 rising from the upper side surface 61 of the lower portion 6 exists below the vent hole 71, the water is reliably stopped. Therefore, water and water vapor do not enter the dressing room. Further, since the upper and lower upper portions 5 and 6 of the ventilation path C are integrated by the connecting wall 7, the strength is high. Further, since the vent cover 2a, 2b covers the difference in the color of the small opening of the vent 71 (because it is a metal cut surface, the surrounding and the color are different), the design is good, and the vent covers 2a, 2b Safety is also high because it prevents injuries that cut the hand at the edge of the small opening of the vent 71 during cleaning. And since the pressing member 3 is attached to the ventilation hole cover 2b for attachment, it is not necessary to process the upper frame 10a. Further, since the on-off valve 1 is a single member that is long in the left-right direction, it can be pressed by the pressing member 3 at any position in the left-right direction. 3 can be attached and the operation position can be changed as appropriate, so that it is possible to easily cope with differences in the right and left hand. Furthermore, since the on-off valve 1 can be forcibly held in the open state by the pressing member 3, it can cope with 24-hour ventilation. The pressing member 3 does not move beyond a predetermined range by the stoppers 31a and 31b, and the on-off valve 1 and the mechanism are prevented from being damaged. Moreover, since the on-off valve 1 is located on the bathroom side and the pressing member 3 can be provided in the middle of the expected door, the exposure of the pressing member 3 to the dressing room side is small and the design is good. Since the pressing member 3 itself is difficult to see, the necessity for considering the design is small, and the degree of freedom in design is high.

次に、本発明の戸の第二実施形態について説明する。第二実施形態は、図１０に示すように、枠体１０と、枠体１０に開閉自在に納めた２枚の障子２０とを備えており、２枚の障子２０が引き違いとなった引戸である。枠体１０は、第一実施形態と同様にアルミニウム製の形材からなるものであり、上下の横枠（上枠１０ａと下枠１０ｂ）と、左右の縦枠１０ｃとを四周枠組みしたものであるが、図８に示すように、２枚の障子２０を納めるため見込幅が長くなっている。見込幅以外の構成は第一実施形態と略同じであり、枠体１０の上枠１０ａは上側部分５と下側部分６とを有していて、下側部分６の下側に、２枚の障子２０の上框２０ａを摺動自在に納めてある。上側部分５の下側面５１と下側部分６の上側面６１の見込方向中央には、両面５１，６１を繋ぐ連結壁７を形成してある。そして連結壁７には、見込方向に貫通する通気口７１を設けてあって、上側部分５の下側面５１と下側部分６の上側面６１との間に換気経路Ｃを形成してある。なお、図９（障子は図示省略してある）に示すように、通気口７１は略矩形で左右方向に長く、左右に９つ並んでいる。そしてそれぞれの通気口７１には、第一実施形態と同じ通気口カバー２ａ，２ｂを取り付けてあり、右側端の通気口７１を除いた左側の８つの通気口７１に取り付けるのはホルダを有さない通気口カバー２ａ（図６）であり、右側端の通気口７１に取り付けるのは取付用通気口カバー２ｂ（図５）である。また、カバー材８及びカバー材８に設けた開閉弁１も、第一実施形態と同じものである。 Next, a second embodiment of the door of the present invention will be described.

Although the pressing member 4 is rotatable, it is restricted by the stopper 41a on the bathroom side so that it does not rotate more clockwise than the state in which the first arm portion 42 faces the bathroom side (the state indicated by the solid line in FIG. 13). ing. Further, the stopper 41b on the dressing room side is restricted from rotating counterclockwise as compared with the state in which the second arm portion faces the dressing room side (the state indicated by the two-dot chain line in FIG. 13).

押圧部材４はねじりコイルバネ４６により時計回りに付勢されているが、これを操作するために、第二腕部４３の先端にワイヤ９１を取り付けてある。ワイヤ９１を右側（図１３の上側）に引くと、押圧部材４がねじりコイルバネ４６の付勢力に抗して反時計回りに回転する。ワイヤ９１は、右側の縦枠１０ｃの左側面に取り付けた滑車９２に掛けられていて下向きに延びており、ワイヤ９１の先端は操作部９に接続されている。操作部９は、図１４に示すように、ケース９３と、スライダ９４からなる。なお、図１４（ａ）、（ｃ）は、右側の縦枠１０ｃに取り付けた操作部９を左側から見た正面図であり、図１４（ｂ）、（ｄ）は、操作部９を脱衣室側から見た縦断面図であって、ここでは図１４（ａ）、（ｃ）の手前側を表側とする。ケース９３は、縦長の箱形であって、右側の縦枠１０ｃの左側面の脱衣室側寄りに取り付けてあり、上端が開口している。そしてケース９３の表側面の上下方向中程には、上下に延びる係合溝９５を形成してある。係合溝９５は、下端に溝幅が広い幅広部９５ａを形成してある。また、スライダ９４は、ケース９３内に上下動自在に納めてあり、表側に開口する箱形の受部９６と、受部９６の表側に被せた蓋部９７とを有していて、蓋部９７の上端にワイヤ９１を接続してある。そして、受部９６及び蓋部９７の内部にはバネ９８を設けてあって、バネ９８は受部９６に対して蓋部９７を表側に付勢している。また、蓋部９７の表側には摘み部９９を形成してある。摘み部９９は、基部９９ａと、頂部９９ｂからなり、基部９９ａは、その幅及び上下長さが係合溝９５の幅広部９５ａと略同じである。そして頂部９９ｂは基部９９ａの表側に形成してあり、基部９９ａよりも幅が狭く、係合溝９５の上側部分の溝幅と略同じである。 The pressing member 4 is urged clockwise by the torsion coil spring 46. In order to operate this, a wire 91 is attached to the tip of the second arm portion 43. When the wire 91 is pulled to the right (upper side in FIG. 13), the pressing member 4 rotates counterclockwise against the biasing force of the torsion coil spring 46. The wire 91 is hung on a pulley 92 attached to the left side surface of the right vertical frame 10 c and extends downward, and the tip of the wire 91 is connected to the operation unit 9. As shown in FIG. 14, the operation unit 9 includes a case 93 and a slider 94. 14 (a) and 14 (c) are front views of the operation unit 9 attached to the right vertical frame 10c as viewed from the left side, and FIGS. 14 (b) and 14 (d) illustrate the operation unit 9 being undressed. It is the longitudinal cross-sectional view seen from the chamber side, Comprising: Here, the near side of FIG. 14 (a), (c) is made into the front side. The case 93 has a vertically long box shape, and is attached to the left side of the right vertical frame 10c near the dressing room, and has an upper end that is open. An engagement groove 95 extending vertically is formed in the middle of the front side surface of the case 93 in the vertical direction. The engaging groove 95 is formed with a wide portion 95a having a wide groove width at the lower end. The slider 94 is housed in the case 93 so as to be movable up and down, and has a box-shaped receiving portion 96 that opens to the front side and a lid portion 97 that covers the front side of the receiving portion 96. A wire 91 is connected to the upper end of 97. A spring 98 is provided inside the receiving portion 96 and the lid portion 97, and the spring 98 biases the lid portion 97 toward the front side with respect to the receiving portion 96. Further, a knob portion 99 is formed on the front side of the lid portion 97. The knob 99 includes a base 99a and a top 99b, and the base 99a has substantially the same width and vertical length as the wide portion 95a of the engagement groove 95. The top 99b is formed on the front side of the base 99a, is narrower than the base 99a, and is substantially the same as the groove width of the upper portion of the engagement groove 95.

続いて、このように構成した押圧部材４及び操作部９の動作について説明する。押圧部材４は、ねじりコイルバネ４６により時計回りに付勢されているので、スライダ９４は、常にワイヤ９１で上側に引っ張られる状態である。スライダ９４の摘み部９９を裏側へ押し込むと、図１４（ａ）、（ｂ）に示すように、基部９９ａがケース９３内に納まり、頂部９９ｂが係合溝９５を上端まで摺動して、スライダ９４がケース９３の上端部で固定される。すると、押圧部材４は時計回りに回転して浴室側のストッパ４１ａに当接した状態となる（図１３において実線で示した状態）。このとき、図１２に示すように、押圧部材４の第一腕部４２が開閉弁１を浴室側に押圧して常に換気経路Ｃを開放状態としており、この状態を押圧状態とよぶ。この際、第一腕部４２の高さが低くなっていることで、開閉弁１の軸部１１を回避しており、また、第一腕部４２の傾斜部４４が、開放状態の開閉弁１の面部１２と略平行になって広い面で当接するので、開閉弁１を確実に保持できる。なお、押圧状態においては、押圧部材４の第一腕部４２が浴室側のストッパ４１ａに当接しており、それ以上押圧部材４が時計回りに回転することは規制されている。一方、この状態からスライダ９４の摘み部９９を係合溝９５の下端の幅広部９５ａの位置まで押し下げると、バネ９８の付勢力によって摘み部９９が表側に飛び出し、基部９９ａが幅広部９５ａに納まって、スライダ９４がケース９３の下端部で固定される。すると、押圧部材４はワイヤ９１に引っ張られて、ねじりコイルバネ４６の付勢力に抗して反時計回りに回転し、脱衣室側のストッパ４１ｂに当接した状態となる（図１３において二点鎖線で示した状態）。このとき、押圧部材４の第一腕部４２が開閉弁１から離隔して開閉弁１は回動自在となっており（図１２（二点鎖線）では自重で垂れ下がって換気経路Ｃを閉鎖している）、この状態を非押圧状態とよぶ。なお、非押圧状態においては、押圧部材４の第二腕部４３が脱衣室側のストッパ４１ｂに当接しており、それ以上押圧部材４が反時計回りに回転することは規制されている。このように、操作部９のスライダ９４を上下させることで、押圧部材４を回転させて押圧状態と非押圧状態を切替可能であり、押圧状態では開閉弁１が常に換気経路Ｃを開放した状態となる。一方、非押圧状態では開閉弁１が回動自在であって、通常は自重で垂れ下がって換気経路Ｃを閉鎖した状態となり、浴室が負圧になると回動して換気経路Ｃを開放した状態となる。 Next, operations of the pressing member 4 and the operation unit 9 configured as described above will be described. Since the pressing member 4 is urged clockwise by the torsion coil spring 46, the slider 94 is always pulled upward by the wire 91. When the knob portion 99 of the slider 94 is pushed back, as shown in FIGS. 14A and 14B, the base portion 99a is housed in the case 93, and the top portion 99b slides through the engagement groove 95 to the upper end. A slider 94 is fixed at the upper end of the case 93. Then, the pressing member 4 rotates clockwise and comes into contact with the bathroom-side stopper 41a (a state indicated by a solid line in FIG. 13). At this time, as shown in FIG. 12, the first arm portion 42 of the pressing member 4 presses the on-off valve 1 toward the bathroom to always open the ventilation path C, and this state is called a pressed state. At this time, since the height of the first arm portion 42 is low, the shaft portion 11 of the on-off valve 1 is avoided, and the inclined portion 44 of the first arm portion 42 is opened and closed. Since the first surface portion 12 is substantially parallel to and abuts on a wide surface, the on-off valve 1 can be reliably held. In the pressed state, the first arm portion 42 of the pressing member 4 is in contact with the bathroom-side stopper 41a, and further rotation of the pressing member 4 in the clockwise direction is restricted. On the other hand, when the knob part 99 of the slider 94 is pushed down to the position of the wide part 95a at the lower end of the engaging groove 95 from this state, the knob part 99 pops out to the front side by the biasing force of the spring 98, and the base part 99a is accommodated in the wide part 95a. Thus, the slider 94 is fixed at the lower end of the case 93. Then, the pressing member 4 is pulled by the wire 91, rotates counterclockwise against the biasing force of the torsion coil spring 46, and comes into contact with the stopper 41b on the dressing room side (the two-dot chain line in FIG. 13). The state shown in). At this time, the first arm portion 42 of the pressing member 4 is separated from the on-off valve 1 so that the on-off valve 1 is rotatable (in FIG. 12 (two-dot chain line), it hangs down by its own weight and closes the ventilation path C. This state is called a non-pressed state. In the non-pressing state, the second arm portion 43 of the pressing member 4 is in contact with the stopper 41b on the dressing room side, and the pressing member 4 is restricted from rotating counterclockwise any further. In this way, by moving the slider 94 of the operation unit 9 up and down, the pressing member 4 can be rotated to switch between the pressed state and the non-pressed state, and the open / close valve 1 always opens the ventilation path C in the pressed state. It becomes. On the other hand, in the non-pressed state, the opening / closing valve 1 is freely rotatable, and normally it is hung down by its own weight to close the ventilation path C, and when the bathroom is under negative pressure, it is rotated to open the ventilation path C. Become.

このように構成した戸の第三実施形態によれば、第一実施形態と同様に、換気経路Ｃの浴室寄りに連結壁７から離隔して開閉弁１を設けてあって、開閉弁１から脱衣室まで距離があるので、浴室側から流入する水や水蒸気が開閉弁１を通過しても脱衣室側まで届きにくい。また、換気経路Ｃの途中に設けた連結壁７が水や水蒸気の浸入を妨げる。特に、通気口７１の下側に下側部分６の上側面６１から立ち上がる連結壁７の壁面が存在しているので、確実に止水される。よって、水や水蒸気が脱衣室に入り込まない。また、連結壁７により換気経路Ｃの上下の上側部分５と下側部分６とが一体になっているので、強度が高い。さらに、通気口カバー２ａ，２ｃが通気口７１の小口の色目の違い（金属の切断面なので周囲と色目が異なる）を覆い隠すので意匠性が良好であり、また、通気口カバー２ａ，２ｃが清掃などの際に通気口７１の小口のエッジで手を切る怪我を防ぐので安全性も高い。そして、取付用通気口カバー２ｃに押圧部材４を取り付けるので、上枠１０ａに加工を施す必要がない。また、開閉弁１は左右に長い単一部材のものであるから、左右方向のどの位置で押圧部材４により押圧してもよいので、任意の通気口７１に取付用通気口カバー２ｃ及び押圧部材４を取り付けて適宜操作位置を変更することができ、左右勝手の違いなどにも容易に対応できる。さらに、押圧部材４によって開閉弁１を強制的に開放状態に保持することができるので、２４時間換気にも対応可能である。そして、この押圧部材４はストッパ４１ａ，４１ｂにより所定範囲以上動くことはなく、開閉弁１や機構の破損を防いでいる。また、開閉弁１が浴室側に位置しており、押圧部材４を戸の見込中程に設けることができるので、押圧部材４の脱衣室側への露出が少なく意匠性が良好であるとともに、押圧部材４自体は見えにくいので意匠性を考慮する必要性が小さく、設計の自由度が高い。そして、押圧部材４をねじりコイルバネ４６によって付勢してあるので、１本のワイヤ９１で押圧状態と非押圧状態の切替操作を行うことができる。このワイヤ９１は、端部が操作部９のスライダ９４に取り付けてあるので、ワイヤ９１がバタついて邪魔になることもない。また、滑車９２によりワイヤ９１を縦枠１０ｃ側に寄せてあって、ワイヤ９１の先端に取り付けたスライダ９４を上下に動かすだけでよいので、操作が容易である。さらに、押圧部材４を取付用通気口カバー２ｃの上辺に取り付けてあり、またねじりコイルバネ４６のコイル部分が回転軸４５の上側部分に外挿され、ねじりコイルバネ４６の足が取付用通気口カバー２ｃの上辺に係合しているので、取付用通気口カバー２ｃの下辺に滞留する結露水などによって、押圧部材４が固着して動きにくくなったり、ねじりコイルバネ４６が腐食したりする不具合が生じない。 According to the third embodiment of the door configured as described above, similarly to the first embodiment, the on-off valve 1 is provided at a distance from the connecting wall 7 near the bathroom of the ventilation path C. Since there is a distance to the dressing room, even if water or water vapor flowing in from the bathroom side passes through the on-off valve 1, it is difficult to reach the dressing room side. Moreover, the connection wall 7 provided in the middle of the ventilation path C prevents water and water vapor from entering. In particular, since the wall surface of the connecting wall 7 rising from the upper side surface 61 of the lower portion 6 exists below the vent hole 71, the water is reliably stopped. Therefore, water and water vapor do not enter the dressing room. Further, since the upper and lower upper portions 5 and 6 of the ventilation path C are integrated by the connecting wall 7, the strength is high. Furthermore, since the vent cover 2a, 2c covers the difference in the color of the small opening of the vent 71 (because it is a metal cut surface, the surrounding and the color are different), the design is good, and the vent covers 2a, 2c Safety is also high because it prevents injuries that cut the hand at the edge of the small opening of the vent 71 during cleaning. And since the pressing member 4 is attached to the ventilation hole cover 2c for attachment, it is not necessary to process the upper frame 10a. Further, since the on-off valve 1 is a single member that is long to the left and right, it can be pressed by the pressing member 4 at any position in the left-right direction, so that the mounting vent hole cover 2c and the pressing member can be attached to any vent hole 71. 4 can be attached and the operation position can be changed as appropriate, so that it is possible to easily cope with differences in the right and left hand. Furthermore, since the on-off valve 1 can be forcibly held in the open state by the pressing member 4, it can cope with 24-hour ventilation. The pressing member 4 does not move beyond a predetermined range by the stoppers 41a and 41b, and the on-off valve 1 and the mechanism are prevented from being damaged. Moreover, since the on-off valve 1 is located on the bathroom side and the pressing member 4 can be provided in the middle of the expected door, the exposure of the pressing member 4 to the dressing room side is small and the design is good. Since the pressing member 4 itself is difficult to see, the necessity for considering the design is small and the degree of design freedom is high. Since the pressing member 4 is urged by the torsion coil spring 46, the switching operation between the pressing state and the non-pressing state can be performed with one wire 91. Since the end portion of the wire 91 is attached to the slider 94 of the operation unit 9, the wire 91 does not flutter and get in the way. Further, since the wire 91 is moved toward the vertical frame 10c by the pulley 92 and the slider 94 attached to the tip of the wire 91 only needs to be moved up and down, the operation is easy. Further, the pressing member 4 is attached to the upper side of the attachment vent cover 2c, the coil portion of the torsion coil spring 46 is extrapolated to the upper portion of the rotating shaft 45, and the foot of the torsion coil spring 46 is attached to the attachment vent port cover 2c. Since the engaging member is engaged with the upper side of the mounting member, the depressing water stays on the lower side of the mounting vent cover 2c and the pressing member 4 is not fixed and hardly moves, and the torsion coil spring 46 is not corroded. .

本発明は、上記の実施形態に限定されない。たとえば、換気経路は、枠体の下枠に形成してもよいし、障子の横框（上框又は下框）に形成してもよい。また、開閉弁は、カバー材ではなく上側部分に直接取り付けてあってもよい。さらに、押圧状態において、押圧部材を開閉弁の開度が異なる複数の位置で固定できるようにして、換気量を選択調整できるようにしてもよい。また、操作部は、ワイヤの先端に取り付けるものであって、押圧状態と非押圧状態の２箇所で固定できるものであればどのような構造であってもよい。たとえば、スライダは、受部と蓋部の２部材からなるものではなく、単一部材の裏面に樹脂製のバネを一体成型したものであってもよいし、スライダの摺動方向が水平方向となるような構造であってもよい。さらに、押圧部材の形状によっては、スライダを上げたときに非押圧状態とし、下げたときに押圧状態とすることもできる。ただし、２４時間換気の状態を維持する場合には、上記の実施形態のように、スライダを上げて押圧部材がねじりコイルバネにより回転した状態で押圧状態となる方が望ましい。 The present invention is not limited to the above embodiment. For example, the ventilation path may be formed in the lower frame of the frame body, or may be formed on the side of the shoji (upper arm or lower arm). The on-off valve may be directly attached to the upper portion instead of the cover material. Further, in the pressed state, the ventilation amount may be selectively adjusted by fixing the pressing member at a plurality of positions where the opening / closing valve opening is different. In addition, the operation unit may be attached to the tip of the wire and may have any structure as long as it can be fixed at two places, a pressed state and a non-pressed state. For example, the slider is not composed of two members, the receiving portion and the lid portion, and may be a single member integrally formed with a resin spring on the back surface, and the slider sliding direction is the horizontal direction. Such a structure may be used. Furthermore, depending on the shape of the pressing member, it can be in a non-pressed state when the slider is raised and in a pressed state when it is lowered. However, in the case of maintaining the 24-hour ventilation state, it is desirable that the slider is lifted and the pressing member is rotated by the torsion coil spring to be in the pressing state as in the above embodiment.
