ところで、断熱性能を向上させるために、各框を樹脂製とした樹脂窓においては、上框および下框と、縦框とを溶着して組み立てるため、各框の外形を揃える必要がある。このため、上框を換気框で構成した場合、換気框以外の下框や縦框を、換気框と同じ見付け寸法にして溶着しなければならず、各框の見付け幅が大きくなり、コストが増加するとともに、意匠性が低下するという課題がある。樹脂枠を用いたＦＩＸ窓においても同じ課題が生じる。したがって、框や枠を樹脂フレームで構成した建具では、換気装置を組み込むことが困難であった。また、アルミ製のフレームを溶着して框や枠を構成する場合も、同様の課題が生じる。
さらに、換気装置では、空気が流通する換気装置内部を容易にメンテナンスできるようにすることも重要である。
本発明の目的は、フレームを有する建具において、換気装置を容易に組み込むことができ、換気装置内部も簡単にメンテナンスできる建具を提供することにある。 By the way, in order to improve heat insulation performance, in the resin window which made each crucible resin, in order to weld and assemble an upper cage and a lower cage, and a vertical cage, it is necessary to equalize the outline of each cage. For this reason, when the upper weir is composed of a ventilating weir, the lower weirs and vertical weirs other than the ventilating weir must have the same dimensions and dimensions as the ventilating weir, and the width of finding each weir increases and the cost While increasing, there is a problem that the designability decreases. The same problem arises in the FIX window using a resin frame. Therefore, it was difficult to incorporate a ventilating device in the fixture which comprised the cage | basket and frame with the resin frame. Further, the same problem arises in the case where a frame made of aluminum is welded to form a crucible or a frame.
Furthermore, in the ventilator, it is also important to be able to easily maintain the inside of the ventilator through which air flows.
An object of the present invention is to provide a fitting having a frame in which a ventilating device can be easily incorporated and the inside of the ventilating device can be easily maintained.

Since the ventilating device 50 is attached to the lower surface of the upper rod 31, the same frame as the fold-off window 1 without the ventilating device 50 can be used for the shoring frame 30 including the upper rod 31. For this reason, compared with the case where the upper weir 31 is configured by a dedicated ventilation rod, the finding dimension of the upper weir 31, that is, the shoji frame 30 can be reduced, the designability can be improved, and the cost can be reduced.
In addition, since the ventilating device 50 is attached to the upper weir 31 using the concave groove 315 to which the ridge 40 is usually attached, there is no need to provide a novel structure for attaching the ventilating device 50 to the upper weir 31 The mounting structure of the ventilation device 50 can be simplified.
Furthermore, since the ventilating apparatus 50 includes the facing member holding portion 62 having the same structure as the lower rod 32 and the vertical rods 33, 34, the multilayer glass 35 can be held using the holding piece 624 and the ridge 40. The number of parts can be reduced because it is not necessary to separately provide parts to hold the multilayer glass 35.

換気装置５０は、上框３１に取り付けられ、かつ、複層ガラス３５を保持する換気装置本体６０と、換気装置本体６０に着脱可能に取り付けられた室外側アタッチメント７０、室内側アタッチメント８０を備えている。このため、室外側アタッチメント７０や室内側アタッチメント８０を取り外すだけで、換気装置本体６０を上框３１や複層ガラス３５から取り外すことなく、換気装置５０内部のメンテナンスを行うことができる。特に、通気部６５を開閉する可動部品である室外側作動板７２や、室内側作動板８２は、室外側アタッチメント７０や室内側アタッチメント８０を取り外すことで、交換や修理などのメンテナンスを容易に行うことができる。
その上、室外側アタッチメント７０、室内側アタッチメント８０は、カバー９０や室内側アタッチメント８０を取り外すことで室内側に露出するネジ８７、７３で取り付けられているので、室内側からの簡単な作業で取り外すことができ、この点でもメンテナンス性を向上できる。
さらに、換気装置５０でメンテナンス頻度が高くなるフィルター８１６は、カバー９０を外すだけで清掃が可能であるため、定期的なメンテナンス作業もきわめて容易に行え、引違い窓１を利用しているユーザーが容易に清掃することができる。その上、フィルター８１６は、面ファスナーなどでアタッチメント本体８１から取り外すことができるので、容易に洗浄したり、交換することができる。 The ventilation device 50 includes a ventilation device main body 60 attached to the upper rod 31 and holding the multilayer glass 35, an outdoor attachment 70 detachably attached to the ventilation device main body 60, and an indoor attachment 80 There is. Therefore, maintenance of the inside of the ventilating apparatus 50 can be performed without removing the ventilating apparatus main body 60 from the upper frame 31 or the multilayer glass 35 only by removing the outdoor side attachment 70 and the indoor side attachment 80. In particular, the outdoor operation plate 72 and the indoor operation plate 82, which are movable parts for opening and closing the ventilation portion 65, easily perform maintenance such as replacement and repair by removing the outdoor attachment 70 and the indoor attachment 80. be able to.
Moreover, since the outdoor attachment 70 and the indoor attachment 80 are attached by the screws 87 and 73 exposed to the indoor side by removing the cover 90 and the indoor attachment 80, they are removed by a simple operation from the indoor side. Maintenance can be improved in this respect as well.
Furthermore, since the filter 816, which requires high maintenance frequency with the ventilator 50, can be cleaned simply by removing the cover 90, regular maintenance work can be performed very easily, and the user using the sliding window 1 can It can be cleaned easily. Moreover, since the filter 816 can be removed from the attachment body 81 by a surface fastener or the like, it can be easily cleaned or replaced.

本実施形態の換気装置５０は外障子３Ａ、内障子３Ｂに設けられているので、換気装置が組み込まれていない障子を用いている引違い窓１であっても、障子３Ａ，３Ｂを換気装置５０付きの障子３Ａ，３Ｂに交換するだけで換気機能を追加することができる。このため、窓枠に換気装置を設ける場合に比べて、簡単なリフォーム作業で換気機能を有する引違い窓１とすることができる。したがって、引違い窓１を有する建物を、障子交換のみで第３種換気設備対応とすることができる。 Since the ventilating device 50 of the present embodiment is provided in the outer shutter 3A and the inner shutter 3B, the ventilating devices 3A and 3B can be used as the ventilating device even if the window 1 is a sliding window that does not incorporate a ventilating device. The ventilation function can be added simply by replacing with 50 shoji 3A, 3B. For this reason, compared with the case where a ventilation system is provided in a window frame, it can be set as the fold-over window 1 which has a ventilation function by easy remodeling operation. Therefore, the building having the switching window 1 can be made compatible with the type 3 ventilation equipment only by shoji replacement.

換気装置５０は、樹脂製の換気装置本体６０を主要構成とし、室内外に連続する金属部品が無いため、断熱性能を向上できる。また、換気装置本体６０や室内側アタッチメント８０の室内面を樹脂製のカバー９０で覆っているので、断熱性能を向上でき、かつ、合成樹脂製の障子枠３０の内観と統一感のある内観意匠とすることができる。
さらに、換気装置本体６０の連結部６３を、室内側連結片６３１、室外側連結片６３２の２つの連結片で構成し、これらの連結片６３１、６３２間の空間を含んで換気装置５０の通気部６５を構成したので、特に、室外側アタッチメント７０、室内側アタッチメント８０が閉鎖されている場合に、通気部６５の断熱性能を向上できる。 The ventilation device 50 has a resin-made ventilation device main body 60 as a main component, and there is no continuous metal part inside and outside the room, so the heat insulation performance can be improved. In addition, since the indoor surfaces of the ventilating apparatus main body 60 and the indoor side attachment 80 are covered with the resin cover 90, the heat insulation performance can be improved, and the interior appearance design has a sense of unity with the interior frame of the plastic frame 30 made of synthetic resin. It can be done.
Furthermore, the connecting portion 63 of the ventilating apparatus main body 60 is constituted by two connecting pieces of the indoor side connecting piece 631 and the outdoor side connecting piece 632, and ventilation of the ventilating apparatus 50 is carried out including the space between these connecting pieces 631, 632 Since the portion 65 is configured, in particular, when the outdoor attachment 70 and the indoor attachment 80 are closed, the heat insulating performance of the ventilation portion 65 can be improved.

換気装置本体６０は、取付部６１、面材保持部６２に複数の中空部を設け、さらに連結部６３は２つの連結片６３１、６３２で構成したので、強度を確保でき、見込み寸法（Ｚ軸方向の寸法）を上框３１と同じスリムな寸法とすることができる。
さらに、室外側作動板７２はＸ軸方向にスライドするため、室外側アタッチメント７０の見込み寸法を小さくできる。このため、換気装置本体６０において連結部６３の見込み方向の位置を室外側にずらして設けることができ、連結部６３から室内側の空間を広く形成できる。したがって、室内側アタッチメント８０の室内側作動板８２が室外側に回動する空間を確保しつつ、換気装置５０の見込み寸法を小さくすることができる。 The ventilation device main body 60 is provided with a plurality of hollow portions in the mounting portion 61 and the face material holding portion 62, and the connecting portion 63 is constituted by the two connecting pieces 631 and 632, so strength can be secured. The dimension of the direction) can be made the same slim dimension as the upper weir 31.
Furthermore, since the outdoor side actuating plate 72 slides in the X-axis direction, the expected dimension of the outdoor side attachment 70 can be reduced. For this reason, the position of the connection direction of the connection part 63 in the ventilation device main body 60 can be shifted to the outdoor side, and the space on the indoor side from the connection part 63 can be widely formed. Therefore, the specifiable dimensions of the ventilation device 50 can be reduced while securing a space in which the indoor side operating plate 82 of the indoor side attachment 80 rotates to the outdoor side.

次に、第２実施形態の引違い窓１Ａについて、図６，７を参照して説明する。
図６は、引違い窓１Ａの外観姿図であり、図７は引違い窓１Ａの上部を示す断面図である。なお、引違い窓１Ａにおいて、第１実施形態の引違い窓１と同じ構成には同一符号を付し、説明を省略する。
引違い窓１Ａは、換気装置５０Ａの室外側アタッチメント７０Ａを室内側に取り外すことができるように構成されている点が、第１実施形態と相違する。
換気装置５０Ａは、換気装置本体６０Ａと、室外側アタッチメント７０Ａと、室内側アタッチメント８０Ａと、カバー９０と、図示略のキャップとを備える。
換気装置本体６０Ａは、第１実施形態の換気装置本体６０と同様に、取付部６１と、面材保持部６２と、連結部６３とを備えている。取付部６１および面材保持部６２間には、通気部６５が形成されている。連結部６３の室外側連結片６３２は、取付部６１および面材保持部６２の室外面に連続して形成されている。この室外側連結片６３２には、図６に示すように、複数のスリット６３６が形成されている。 Next, the reflection window 1A of the second embodiment will be described with reference to FIGS.
FIG. 6 is an external appearance view of the switching window 1A, and FIG. 7 is a cross-sectional view showing an upper portion of the switching window 1A. In addition, in the reflection window 1A, the same components as those of the reflection window 1 of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The difference window 1A is different from the first embodiment in that it is configured so that the outdoor attachment 70A of the ventilator 50A can be removed to the indoor side.
The ventilator 50A includes a ventilator main body 60A, an outdoor attachment 70A, an indoor attachment 80A, a cover 90, and a cap (not shown).
The ventilator main body 60 </ b> A includes the attachment portion 61, the face material holding portion 62, and the connection portion 63 as in the ventilator main body 60 of the first embodiment. A ventilation portion 65 is formed between the mounting portion 61 and the facing material holding portion 62. The outdoor side connecting piece 632 of the connecting portion 63 is continuously formed on the chamber outer surface of the mounting portion 61 and the facing member holding portion 62. As shown in FIG. 6, the outdoor connection piece 632 has a plurality of slits 636 formed therein.

室外側連結片６３２の室内側には、室外側アタッチメント７０Ａが配置される。室外側アタッチメント７０Ａは、第１実施形態の室外側アタッチメント７０と同様に、通気孔７１３を有するアタッチメント本体７１と、通気孔７２３を有する室外側作動板７２とを備える。通気孔７１３は、スリット６３６に合わせて形成されている。すなわち、通気孔７１３は、スリット６３６と開口面積、サイズがほぼ同じであり、見込み方向に重なる位置に設けられ、通気部６５に連通している。この通気孔７１３は、第１実施形態と同じく、図示略の室外側連結部材、室内側連結部を介して操作ツマミに連結された室外側作動板７２を、換気装置５０の長手方向（Ｘ軸方向）に沿ってスライド移動させることで、開閉される。したがって、室外側アタッチメント７０Ａは、通気部６５の室外側開口を開閉する。
ここで、第１実施形態の室外側アタッチメント７０は、換気装置本体６０に対して室外側に取り外し可能に取り付けられている。一方、第２実施形態の室外側アタッチメント７０Ａは、換気装置本体６０Ａに対して、室内側に取り外し可能に取り付けられている。 An outdoor attachment 70A is disposed on the indoor side of the outdoor connection piece 632. Similar to the outdoor attachment 70 of the first embodiment, the outdoor attachment 70A includes an attachment main body 71 having a vent 713 and an outdoor operation plate 72 having a vent 723. The vent 713 is formed in alignment with the slit 636. That is, the vent hole 713 has an opening area and size substantially the same as those of the slit 636, is provided at a position overlapping in the prospective direction, and communicates with the vent portion 65. Similar to the first embodiment, the vent hole 713 is provided with the outdoor side actuating member 72 connected to the operation knob via the outdoor side connecting member (not shown) and the indoor side connecting portion in the longitudinal direction of the ventilation device 50 (X axis It is opened and closed by sliding along the direction. Therefore, the outdoor-side attachment 70A opens and closes the outdoor-side opening of the vent portion 65.
Here, the outdoor-side attachment 70 of the first embodiment is removably attached to the outdoor side with respect to the ventilator main body 60. On the other hand, the outdoor-side attachment 70A of the second embodiment is removably attached to the indoor side with respect to the ventilator main body 60A.

室内側アタッチメント８０Ａは、第１実施形態の室内側アタッチメント８０と同様に、通気部６５に連通可能な通気孔８１５が形成されたアタッチメント本体８１と、アタッチメント本体８１に対して回動自在に取り付けられた室内側作動板８２と、図示略の端部部材、ガイド部材、操作ツマミとを備えている。室内側作動板８２は、操作ツマミの開閉操作によって、下端部が室外側および室内側に移動し、アタッチメント本体８１の通気孔８１５を開閉できる。したがって、室内側アタッチメント８０Ａは、通気部６５の室内側開口を開閉する。
室内側アタッチメント８０Ａは、第１実施形態の室内側アタッチメント８０と同じく、換気装置本体６０に対して室内側に取り外し可能に取り付けられている。 The indoor side attachment 80A is rotatably attached to the attachment main body 81 in which the vent hole 815 capable of communicating with the ventilating portion 65 is formed, and the attachment main body 81, similarly to the indoor side attachment 80 of the first embodiment. The indoor side operation plate 82, an end member (not shown), a guide member, and an operation knob are provided. The lower end portion of the indoor side operation plate 82 moves to the outdoor side and the indoor side by the opening and closing operation of the operation knob, and the air vent 815 of the attachment main body 81 can be opened and closed. Therefore, the indoor side attachment 80A opens and closes the indoor side opening of the ventilation part 65.
The indoor side attachment 80A is removably attached to the indoor side with respect to the ventilator main body 60, similarly to the indoor side attachment 80 of the first embodiment.

このような第２実施形態によれば、前記第１実施形態と同様の効果を奏することができる。さらに、室内側アタッチメント８０Ａに加えて室外側アタッチメント７０Ａも室内側に取り外すことができるので、作業者は、各アタッチメント７０Ａ，８０Ａを取り外してメンテナンスする場合に、引違い窓１Ａの室外側に移動して作業する必要が無く、換気装置５０Ａ内部のメンテナンスを容易に行うことができる。
また、室外側アタッチメント７０Ａが室外面に露出しないため、換気装置５０Ａの外観意匠を向上できる。すなわち、換気装置５０Ａにおいて、室外側に露出するのは、換気装置本体６０Ａであり、室外側アタッチメント７０Ａは室外側連結片６３２で覆われているので、図６に示すようにスリット６３６が形成された換気装置本体６０Ａのみが室外側に露出する。したがって、換気装置本体６０Ａおよび室外側アタッチメント７０Ａが室外側に露出する場合と比較して、換気装置５０Ａの外観意匠を向上できる。 According to such a second embodiment, the same effect as that of the first embodiment can be obtained. Furthermore, since the outdoor side attachment 70A can be removed to the indoor side in addition to the indoor side attachment 80A, the worker moves to the outdoor side of the sliding window 1A when maintenance is performed by removing each attachment 70A, 80A. There is no need to carry out maintenance work, and maintenance inside the ventilator 50A can be easily performed.
Moreover, since the outdoor side attachment 70A is not exposed to the chamber outer surface, the external appearance design of the ventilator 50A can be improved. That is, in the ventilating device 50A, the ventilating device main body 60A is exposed to the outdoor side, and the outdoor side attachment 70A is covered with the outdoor side connecting piece 632, so the slits 636 are formed as shown in FIG. Only the ventilator main body 60A is exposed to the outdoor side. Therefore, the appearance design of the ventilation device 50A can be improved as compared with the case where the ventilation device main body 60A and the outdoor attachment 70A are exposed to the outdoor side.
