本発明は、引違い窓や片引き窓等の建具に関し、詳しくは、下枠の上面が略平坦（フラット）に形成され、室内外の床材上面との段差を小さくしたバリアフリータイプの掃出し窓に用いられる建具に関する。 TECHNICAL FIELD The present invention relates to a fitting such as a sliding window or a sliding window, and more specifically, a barrier-free type sweep window in which the upper surface of a lower frame is formed to be substantially flat (flat) and the step between the indoor and outdoor floor materials is reduced. It relates to joinery used in

住宅等のテラスやバルコニー等に面した外壁位置には、居住者が室内からテラス等に出入りするための掃出し窓が設けられている。このような掃出し窓としては、外壁に固定された窓枠と、この窓枠内にスライド自在に支持された可動障子とを備えた、引違い窓や片引き窓等の建具（サッシ窓）が一般的である。
このサッシ窓として、近年、居住者の高齢化や、車いす利用者の利便性等に配慮したバリアフリータイプの掃出し窓が提案されている（例えば、特許文献１参照）。 Sweep windows for residents to enter and exit the terrace and the like from the room are provided at the outer wall positions facing the terrace and balcony of the house. As such a sweep window, a fitting (sash window) such as a sliding window or a single sliding window, which includes a window frame fixed to the outer wall and a movable shoji that is slidably supported in the window frame, is generally used. Is.
As this sash window, in recent years, a barrier-free type sweep window has been proposed in consideration of the aging of residents and the convenience of wheelchair users (see, for example, Patent Document 1).

特許文献１に記載された掃出し窓は、上面が略フラットに形成された下枠と、室内外の障子とを備えた引違い窓であって、下枠上面には、障子の戸車を案内する案内溝と、障子下端の室外側に垂下されたスライド片を挿入するスライド溝とが形成されている。そして、障子のスライド片の室内側側面に取り付けられた気密材と、スライド溝の室外側側面とが当接することで、タイトラインが形成されるようになっている。 The sweep window described in Patent Document 1 is a sliding window having a lower frame whose upper surface is formed to be substantially flat, and indoor and outdoor shojis, and guides a shoji door to the upper surface of the lower frame. A guide groove and a slide groove into which a slide piece suspended from the outdoor side of the lower end of the shoji is inserted are formed. And the tight line is formed by the airtight material attached to the indoor side surface of the sliding piece of the shoji and the outdoor side surface of the slide groove abutting.

しかしながら、前記特許文献１に記載の下枠および障子の構造では、スライド溝が案内溝よりも室外側に形成されており、障子のガラスパネルと下框との間に雨水等が浸入した場合には、この雨水等が下枠上面に落下して案内溝や気密材の上面に溜まってしまうことになる。そして、特に、室内側の案内溝や室内側障子の気密材の上面に溜まった雨水等は、気密材に阻まれて排水されずに案内溝や気密材に沿って流れ、室内側障子の召合せ部を超えて室内側まで浸入する可能性がある。このように従来の構造では、障子を閉じた際に室内側に露出する下枠上面に雨水等が浸入するという問題がある。 However, in the structure of the lower frame and the shoji described in Patent Document 1, the slide groove is formed on the outdoor side of the guide groove, and rainwater or the like enters between the glass panel of the shoji and the lower arm. The rainwater or the like falls on the upper surface of the lower frame and accumulates on the upper surface of the guide groove or the airtight material. In particular, rainwater collected on the indoor guide groove and the top of the airtight material of the indoor shoji flows along the guide groove and the airtight material without being drained by the airtight material. There is a possibility of entering the indoor side beyond the fitting section. As described above, the conventional structure has a problem that rainwater or the like enters the upper surface of the lower frame exposed to the indoor side when the shoji is closed.

本発明の目的は、下枠上面をフラットにしても室内側に露出する下枠上面への雨水等の浸入を確実に防止することができる建具を提供することにある。 An object of the present invention is to provide a joinery that can reliably prevent intrusion of rainwater and the like into the lower frame upper surface exposed to the indoor side even if the lower frame upper surface is flat.

In addition, the material of each airtight material 31A, 31B is not specifically limited.

次に、レール間上面部材３２は、長尺角筒状に形成されたアルミ押出形材製の部材であり、図５、６に示すように、下枠１２の長手方向途中位置で三分割されており、図５、６中、左側から第１〜第３のレール間上面部材３２Ａ，３２Ｂ，３２Ｃの３つの部材から構成されている。第１および第２のレール間上面部材３２Ａ，３２Ｂの一方側（図５中、左側）端部、および第３のレール間上面部材３２Ｃの他方側（図５中、右側）端部には、それぞれつまみ部材３２１が取り付けられている。そして、第１および第２のレール間上面部材３２Ａ，３２Ｂは、第１のレール間上面部材３２Ａのつまみ部材３２１を縦枠１３に当接させるとともに、この第１のレール間上面部材３２Ａの他方側端部に第２のレール間上面部材３２Ｂのつまみ部材３２１を当接させ、第２のレール間上面部材３２Ｂの他方側端部を、下枠本体１２４に設けられた風止板３８に当接させて取り付けられている。また、第３のレール間上面部材３２Ｃは、一方側端部を風止板３８に当接させ、他方側端部のつまみ部材３２１を縦枠１３に当接させて取り付けられている。 Next, the top surface member 32 between the rails is a member made of an aluminum extruded shape formed in a long rectangular tube shape, and is divided into three at a midway position in the longitudinal direction of the lower frame 12 as shown in FIGS. 5 and 6, the first to third inter-rail upper surface members 32A, 32B, and 32C are configured from the left side. At one end (left side in FIG. 5) of the first and second upper surface members 32A, 32B between the first rail and the second rail, and at the other end (right side in FIG. 5) of the third upper surface member 32C between the rails, A knob member 321 is attached to each. The first and second rail upper surface members 32A and 32B abut the knob member 321 of the first rail upper surface member 32A against the vertical frame 13, and the other of the first rail upper surface members 32A. The knob member 321 of the second top surface member 32B between the rails is brought into contact with the side end portion, and the other end portion of the second top surface member 32B between the rails is brought into contact with the windshield plate 38 provided on the lower frame main body 124. It is attached in contact. The third inter-rail upper surface member 32 C is attached with one end abutted against the windshield 38 and the knob member 321 at the other end abutted with the vertical frame 13.

また、第１および第２のレール間上面部材３２Ａ，３２Ｂは、室外側障子１５Ｂを開放した状態で、先ず第１のレール間上面部材３２Ａを上方に引き抜き、つづいて第２のレール間上面部材３２Ｂをスライドさせてから上方に引き抜いて取り外される。一方、第３のレール間上面部材３２Ｃは、室内側障子１５Ａを開放した状態で、上方に引き抜いて取り外されるようになっている。このように、レール間上面部材３２を下枠本体１２４から取り外すことによって、下枠内部空間１２５が上方に開口するため、掃除機等を用いて下枠内部空間１２５の清掃を容易に行うことができるようになっている。 In addition, the first and second upper surface members 32A, 32B between the rails first pull the upper surface member 32A between the first rail upward and then the second upper surface member between the rails with the outdoor shoji 15B open. After sliding 32B, it is pulled out and removed. On the other hand, the third inter-rail upper surface member 32C is pulled out and removed with the indoor shoji 15A opened. Thus, by removing the rail upper surface member 32 from the lower frame main body 124, the lower frame inner space 125 opens upward, so that the lower frame inner space 125 can be easily cleaned using a vacuum cleaner or the like. It can be done.

一方、室内側上面部材３３は、下枠本体１２４における室内部材１２１の室内側凹溝部１２１Ｂに沿って上方に開口した凹溝状に形成されている。そして、室内側上面部材３３の上面は、室内部材１２１の上面よりも若干低い位置で、室内側レール部３０Ａの上面部３０１と略同一高さ位置に設けられている。このような室内側上面部材３３によれば、室内側レール部３０Ａと室内側上面部材３３との隙間１２６から室内側凹溝部１２１Ｂに入ったゴミや埃が室内側上面部材３３に溜まるようになっている。そして、室内側上面部材３３を下枠本体１２４から取り外すことで、溜まったゴミや埃を排出できて室内側凹溝部１２１Ｂの清掃を容易に行うことができるようになる。 On the other hand, the indoor upper surface member 33 is formed in a concave groove shape that opens upward along the indoor concave groove portion 121 B of the indoor member 121 in the lower frame main body 124. The upper surface of the indoor-side upper surface member 33 is provided at a position that is slightly lower than the upper surface of the indoor member 121 and at substantially the same height as the upper surface portion 301 of the indoor-side rail portion 30A. According to such an indoor upper surface member 33, dust and dirt that enter the indoor concave groove portion 121B through the gap 126 between the indoor rail portion 30A and the indoor upper surface member 33 are accumulated in the indoor upper surface member 33. ing. Then, by removing the indoor-side upper surface member 33 from the lower frame main body 124, accumulated dust and dust can be discharged, and the indoor-side recessed groove 121B can be easily cleaned.

次に、図５〜図７に示すように、下枠１２の長手方向略中央部（召合せ部２３の下方）の下枠本体１２４には気密部材である風止板３８が設けられている。この風止板３８は、下枠内部空間１２５を左右に仕切る、すなわち障子１５を閉じた状態で室内空間に連通する図５の左側と室外空間に連通する図５の右側とに下枠内部空間１２５を仕切る部材である。この風止板３８は、閉じた障子１５の召合せ側縦框１８Ａ，１８Ｂの下端部に当接するヒレ状の複数の当接片３８１を有しており、これにより召合せ部２３における見込み方向の気密ラインが形成されている。また、風止板３８の左右両端部には、第２および第３のレール間上面部材３２Ｂ，３２Ｃの端部に当接してこれらを位置決めする位置決め部３８２が形成されている。 Next, as shown in FIGS. 5 to 7, a windshield plate 38, which is an airtight member, is provided on the lower frame main body 124 in the substantially central portion in the longitudinal direction of the lower frame 12 (below the summing portion 23). . The windshield 38 partitions the lower frame internal space 125 into the left and right sides, that is, the lower frame internal space on the left side of FIG. 5 that communicates with the indoor space with the shoji 15 closed and the right side of FIG. 5 that communicates with the outdoor space. 125 is a member that partitions 125. The windbreak plate 38 has a plurality of fin-shaped contact pieces 381 that contact the lower ends of the summing-side vertical rods 18A and 18B of the closed shoji 15 so that the prospective direction in the summing portion 23 can be obtained. The airtight line is formed. Further, positioning portions 382 are formed at both left and right end portions of the windshield plate 38 to abut against the end portions of the second and third inter-rail upper surface members 32B and 32C and position them.

次に、下枠１２における気密、水密構造について、図７〜図１１に基づいて詳しく説明する。
図７および図８は、引違い窓１０における召合せ部の下部を示す斜視図、および縦断面図である。図９は、室内側障子１５Ａの下部を拡大して示す縦断面図である。図１０(Ａ)〜(Ｃ)は、室内側の召合せ框１８Ａ下端に設けられる摺動部材４０を示す三面図である。図１１は、摺動部材４０を示す斜視図である。 Next, the airtight and watertight structure in the lower frame 12 will be described in detail with reference to FIGS.
7 and 8 are a perspective view and a longitudinal sectional view showing the lower part of the summing portion in the sliding window 10. FIG. 9 is an enlarged longitudinal sectional view showing the lower part of the indoor shoji 15A. 10 (A) to 10 (C) are three views showing the sliding member 40 provided at the lower end of the indoor summoning bowl 18A. FIG. 11 is a perspective view showing the sliding member 40.

引違い窓１０の召合せ部２３を構成する室内側障子１５Ａの縦框（召合せ框）１８Ａ下端には、樹脂製一体成形品の摺動部材４０が取り付けられている。この摺動部材４０は、縦框１８Ａの下方から挿入されるとともにビス止めにより取り付けられるもので、下方に突出した室内外２つの摺動片４１を備えて形成されている。これらの摺動片４１は、障子１５における下框１７の下端室内外両縁から下方に突出して形成された突出片１７６に連続して設けられ、これらの摺動片４１および突出片１７６によって前記垂下片１７５が構成されている。従って、摺動部材４０の摺動片４１は、下枠１２上面に形成された隙間１２６に挿入されるとともに、室外側の摺動片４１には、室内側の気密材３１Ａが室内側側面に当接され、風止板３８の当接片３８１が室外側側面および下端縁に当接されている。このように風止板３８による見込み方向の気密ラインと、気密材３１による横方向の気密ラインとが連続形成されるようになっている。 A sliding member 40 made of a resin integrally molded product is attached to the lower end of the vertical saddle (summing rod) 18A of the indoor shoji 15A that constitutes the summing portion 23 of the sliding window 10. The sliding member 40 is inserted from the lower side of the vertical rod 18A and attached by screwing, and is formed with two indoor and outdoor sliding pieces 41 protruding downward. These sliding pieces 41 are continuously provided on projecting pieces 176 that are formed to project downward from both ends of the lower end of the lower lid 17 in the shoji 15 and are formed by the sliding pieces 41 and the projecting pieces 176. A drooping piece 175 is formed. Therefore, the sliding piece 41 of the sliding member 40 is inserted into the gap 126 formed on the upper surface of the lower frame 12, and the indoor airtight material 31 A is placed on the indoor side surface of the outdoor sliding piece 41. The contact piece 381 of the windshield plate 38 is in contact with the outdoor side surface and the lower end edge. In this way, the airtight line in the expected direction by the windshield plate 38 and the airtight line in the horizontal direction by the airtight material 31 are continuously formed.

以上のような風止板３８と摺動部材４０とによって引違い窓１０の召合せ部２３下方における気密、水密構造が構成され、室外空間から雨水等が浸入しないようになっている。しかし、強風を伴う降雨の場合などには、障子１５のガスケット１９Ａの弾性変形によりガラスパネル１９とガスケット１９Ａとの間から雨水等が下框１７や縦框１８内部に浸入してしまう可能性がある。このように下框１７や縦框１８内部に浸入した雨水は、図９に一点鎖線の矢印で示すように、レール部３０の上面に落下し、レール部３０の上面部３０１や気密材３１の上面に溜まってしまう。これは、気密材３１と垂下片１７５とが当接しているため、雨水が下方に落下できないからであり、溜まった雨水は、レール部３０の上面部３０１や気密材３１に沿って流れることとなる。そして、室内側レール部３０Ａにおいて、上面部３０１や気密材３１Ａの上面は、横気密ラインよりも室内側、つまり室内空間に位置するため、室内側障子１５Ａの縦框（召合せ框）１８Ａを超えて図７の右側に雨水が流れると、室内側に露出した下枠上面（上面部３０１、気密材３１Ａの上面）に雨水が流入してしまうこととなる。 The windshield plate 38 and the sliding member 40 as described above form an airtight and watertight structure below the summing portion 23 of the sliding window 10 so that rainwater or the like does not enter from the outdoor space. However, in the case of rain accompanied by strong winds, etc., there is a possibility that rainwater or the like may enter the lower rod 17 or the vertical rod 18 from between the glass panel 19 and the gasket 19A due to elastic deformation of the gasket 19A of the shoji 15. is there. The rainwater that has entered the lower rod 17 or the vertical rod 18 in this manner falls to the upper surface of the rail portion 30 as indicated by the dashed line arrow in FIG. 9, and the upper surface portion 301 of the rail portion 30 and the airtight material 31 It accumulates on the top surface. This is because the airtight material 31 and the hanging piece 175 are in contact with each other, so that rainwater cannot fall downward. The accumulated rainwater flows along the upper surface portion 301 of the rail portion 30 and the airtight material 31. Become. In the indoor rail portion 30A, the upper surface portion 301 and the upper surface of the airtight material 31A are located on the indoor side, that is, the indoor space with respect to the horizontal airtight line. If rainwater flows to the right side of FIG. 7 beyond that, rainwater will flow into the lower frame upper surface (upper surface portion 301, upper surface of the airtight material 31A) exposed to the indoor side.

そこで、本実施形態の摺動部材４０の摺動片４１には、室内側のレール部３０Ａの上面部３０１や気密材３１Ａに沿って流れてきた雨水等を排水するための排水手段である排水開口部４２が設けられている。この排水開口部４２は、室外側の摺動片４１の室内外の側面に開口し、かつレール部３０Ａの上面部３０１および気密材３１Ａの上面よりも高い位置から摺動片４１の下端縁で開口された開放形状とされている。そして、排水開口部４２は、室内側障子１５Ａを閉じた状態において、図７に示すように、風止板３８の当接片３８１、つまり見込み方向の気密ラインよりも室内側（図中、右側）に形成されており、室外空間の風雨等が排水開口部４２から室内側に入り込まないようになっている。このような排水開口部４２により、室内側のレール部３０Ａの上面部３０１や気密材３１Ａに沿って流れてきた雨水等は、下枠１２上面の隙間１２６を介して下枠内部空間１２５に排出され、前記排水弁３９を介して室外空間に排水されるようになっている。 Therefore, the sliding piece 41 of the sliding member 40 of the present embodiment is drainage that is a drainage means for draining rainwater and the like flowing along the upper surface portion 301 of the indoor rail portion 30A and the airtight material 31A. An opening 42 is provided. The drainage opening 42 opens at the indoor / outside side surface of the sliding piece 41 on the outdoor side, and at the lower edge of the sliding piece 41 from a position higher than the upper surface portion 301 of the rail portion 30A and the upper surface of the airtight material 31A. It is an open shape with an opening. Then, as shown in FIG. 7, the drain opening 42 is located on the indoor side of the windshield plate 38, that is, on the airtight line in the prospective direction (right side in the figure), as shown in FIG. ) So that wind and rain in the outdoor space do not enter the indoor side through the drainage opening 42. By such a drainage opening 42, rainwater or the like flowing along the upper surface portion 301 of the indoor rail portion 30A or the airtight material 31A is discharged to the lower frame internal space 125 through the gap 126 on the upper surface of the lower frame 12. The water is drained to the outdoor space through the drain valve 39.

また、摺動部材４０の底面部４３は、レール部３０Ａの上面部３０１および戸車案内部３０２に沿った形状になっている、すなわち、上面部３０１に沿った略水平な部分と戸車案内部３０２に沿って上向き凸な部分とを有して形成されている。従って、レール部３０Ａの上面部３０１や気密材３１Ａに沿って流れてきた雨水等が、上面部３０１や気密材３１Ａに近接した摺動部材４０の底面部４３に阻まれ、室内側障子１５Ａの縦框（召合せ框）１８Ａを超えて室内側に流入しにくくなっている。 Further, the bottom surface portion 43 of the sliding member 40 has a shape along the upper surface portion 301 and the door guide portion 302 of the rail portion 30A, that is, a substantially horizontal portion along the upper surface portion 301 and the door wheel guide portion 302. And an upwardly convex portion. Accordingly, rainwater or the like flowing along the upper surface portion 301 or the airtight material 31A of the rail portion 30A is blocked by the bottom surface portion 43 of the sliding member 40 adjacent to the upper surface portion 301 or the airtight material 31A, and the indoor side shoji 15A It is difficult for it to flow into the indoor side beyond the vertical fence (summit bowl) 18A.

このような本実施形態によれば、以下のような効果がある。
（１）すなわち、室内側のレール部３０Ａの上面部３０１や気密材３１Ａに沿って流れてきた雨水等が、摺動部材４０の摺動片４１に形成した排水開口部４２から排水されるので、下枠１２上面をフラットに形成するレール部３０Ａ上面に浸入した水を、召合せ部２３を超えて室内側まで流入させずに、その手前で下枠内部空間１２５に落下させて排水することができ、障子１５を閉じた際に室内側に露出した下枠１２上面への雨水等の浸入がない引違い窓１０を構成することができる。 According to this embodiment, there are the following effects.
(1) That is, rainwater or the like flowing along the upper surface portion 301 of the indoor rail portion 30A or the airtight material 31A is drained from the drain opening 42 formed in the sliding piece 41 of the sliding member 40. In addition, water that has entered the upper surface of the rail portion 30A that forms the upper surface of the lower frame 12 in a flat manner does not flow into the indoor side beyond the summing unit 23, but is dropped into the lower frame internal space 125 before it is drained. The sliding window 10 can be configured so that rainwater or the like does not enter the upper surface of the lower frame 12 exposed to the indoor side when the shoji 15 is closed.

（２）また、樹脂製一体成形品の摺動部材４０の摺動片４１に排水開口部４２を設けることで、アルミ形材製の下框１７に排水開口部４２を形成するための加工を施す必要がなくなり、加工手間を軽減することができる。つまり、下框１７がアルミ形材製であることから、このアルミ形材に加工を施すと手間が増加してしまうが、摺動部材４０はアルミ形材製ではなく樹脂成形品であるため、このような摺動部材４０の摺動片に排水開口部４２を形成することは比較的容易で、加工手間の増加を招かずに製造することができる。 (2) Further, by providing the drainage opening 42 on the sliding piece 41 of the sliding member 40 of the resin integrally molded product, the processing for forming the drainage opening 42 on the lower rod 17 made of aluminum shape material is performed. This eliminates the need to apply and can reduce processing effort. That is, since the lower bar 17 is made of an aluminum shape, the labor is increased when the aluminum shape is processed, but the sliding member 40 is not made of an aluminum shape but a resin molded product. It is relatively easy to form the drain opening 42 in the sliding piece of such a sliding member 40, and it can be manufactured without causing an increase in processing labor.

（３）さらに、排水開口部４２がレール部３０の上面部３０１や気密材３１の上面よりも高い位置から摺動片４１の下端縁まで延長して形成されているので、レール部３０や気密材３１の上面に沿って流れてきた水を確実に摺動片４１の下方、つまりレール部３０とレール間上面部材３２との隙間に落下させることができる。 (3) Further, since the drain opening 42 is formed extending from a position higher than the upper surface 301 of the rail portion 30 and the upper surface of the airtight material 31 to the lower end edge of the sliding piece 41, the rail portion 30 and the airtight The water flowing along the upper surface of the material 31 can be surely dropped below the sliding piece 41, that is, into the gap between the rail portion 30 and the rail upper surface member 32.

（４）また、摺動部材４０の底面部４３がレール部３０の上面に近接して設けられることで、レール部３０や気密材３１に沿って流れてきた雨水等が摺動部材４０の底面部４３に阻まれて召合せ部２３下方に浸入しにくくでき、室内側への雨水等の浸入をより確実に防止することができる。 (4) Since the bottom surface portion 43 of the sliding member 40 is provided close to the top surface of the rail portion 30, rain water or the like flowing along the rail portion 30 or the airtight material 31 can be removed from the bottom surface of the sliding member 40. It is blocked by the portion 43, making it difficult to enter the lower portion of the summoning portion 23, and intrusion of rainwater or the like into the indoor side can be more reliably prevented.
