次に、上枠２１、下枠２２および左右の縦枠２３，２４について、図５に拡大して示す下枠２２を例に説明する。
図５に示すように、下枠２２の見込み片部２２０は、見込み方向つまり室内外方向に沿って形成され、複数の中空部（ホロー部）を有する形状とされている。室外見付け片部２１０は、見込み片部２２０の見込み方向の略中間部から各枠の見付け方向（下枠２２では上方）に突設されている。
見込み片部２２０は、室外見付け片部２１０よりも室外側に延出する室外延出部２２１と、室外延出部２２１の室外側に延出され、かつ、室外延出部２２１よりも厚さ寸法が小さい室外端部２２２とを備えている。
室内見付け片部２３０は、見込み片部２２０の室内側端部から各枠の見付け方向に突設されている。 Next, the upper frame 21, the lower frame 22, and the left and right vertical frames 23 and 24 will be described using the lower frame 22 shown in an enlarged manner in FIG. 5 as an example.
As shown in FIG. 5, the prospective piece 220 of the lower frame 22 is formed along the prospective direction, that is, the indoor / outdoor direction, and has a shape having a plurality of hollow parts (hollow parts). The outdoor finding piece portion 210 is provided so as to project from the substantially middle portion of the prospective direction of the prospective piece portion 220 in the finding direction of each frame (upward in the lower frame 22).
The prospective piece 220 is extended to the outdoor side of the outdoor extension piece 221 and to the outdoor side of the outdoor extension piece 221 and is thicker than the outdoor extension 221. And an outdoor end 222 having a small size.
The room finding piece 230 is provided so as to protrude from the indoor side end of the prospective piece 220 in the direction in which each frame is found.

室外延出部２２１の見込み面（上面）には、断面略Ｌ字状に形成された係合片部２２３が一体に形成されている。係合片部２２３は、見込み片部２２０の上面から見付け方向（下枠２２では上方）に突設され、さらに室外方向に延長されている。
係合片部２２３よりも室外側には、室外延出部２２１と室外端部２２２との厚さ寸法の差で生じる段差部２２４が形成されている。このため、室外延出部２２１の上面と、室外端部２２２の上面は、段差部２２４を介して連続している。 On the prospective surface (upper surface) of the outdoor extension 221, an engagement piece 223 having a substantially L-shaped cross section is integrally formed. The engagement piece portion 223 protrudes from the upper surface of the prospective piece portion 220 in the direction of finding (upward in the lower frame 22), and further extends in the outdoor direction.
A stepped portion 224 is formed on the outdoor side of the engagement piece portion 223, which is generated due to a difference in thickness between the outdoor extending portion 221 and the outdoor end portion 222. For this reason, the upper surface of the outdoor extension part 221 and the upper surface of the outdoor end part 222 are continuous via the step part 224.

室外端部２２２の上面には、突出片部２２５と、取付片部２２６とが一体に形成されている。
突出片部２２５は、段差部２２４よりも室外側の位置で、室外端部２２２の上面から見付け方向（下枠２２では上方）に突設されている。このため、突出片部２２５と段差部２２４との間には溝が形成されている。
取付片部２２６は、突出片部２２５よりも室外側の位置で、室外端部２２２の上面から見付け方向に突設され、さらに室外方向に延長されている。このため、突出片部２２５と取付片部２２６との間にも溝が形成されている。この突出片部２２５と取付片部２２６との溝は、前記押縁２７の取付溝としても利用されている。
ここで、突出片部２２５および取付片部２２６の上面は、室外延出部２２１の上面とほぼ同じ高さ位置とされている。 A projecting piece 225 and a mounting piece 226 are integrally formed on the upper surface of the outdoor end 222.
The protruding piece portion 225 is provided so as to protrude from the upper surface of the outdoor end portion 222 in the direction of finding (upward in the lower frame 22) at a position outside the stepped portion 224. For this reason, a groove is formed between the protruding piece portion 225 and the stepped portion 224.
The attachment piece 226 protrudes in the direction of finding from the upper surface of the outdoor end 222 at a position outside the protruding piece 225 and further extends in the outdoor direction. For this reason, a groove is also formed between the projecting piece 225 and the mounting piece 226. The groove between the protruding piece 225 and the attachment piece 226 is also used as the attachment groove of the pressing edge 27.
Here, the upper surfaces of the protruding piece part 225 and the attachment piece part 226 are substantially the same height as the upper surface of the outdoor extending part 221.

室外見付け片部２１０には、前記気密材２６が装着される装着溝２１１が形成されている。また、室外見付け片部２１０の上端部の室外面には、室外側に僅かに突出する突起２１２が形成されている。
下枠２２の下レール２４２には溝２４５が形成され、図３に示すように戸車４６を案内するレール部材２４６が保持されている。 A mounting groove 211 in which the airtight member 26 is mounted is formed in the outdoor finding piece 210. In addition, a projection 212 slightly protruding outward is formed on the outdoor surface of the upper end portion of the outdoor finding piece 210.
A groove 245 is formed in the lower rail 242 of the lower frame 22, and a rail member 246 for guiding the door wheel 46 is held as shown in FIG.

上枠２１および縦枠２３、２４は、下枠２２における下レール２４２に対応する上レール２４１、戸当り部２４３、２４４の形状が相違する点と、下枠２２の室外端部２２２の下面には断面Ｌ字状の係止部２２７が形成されているのに対し、上枠２１および縦枠２３、２４には形成されていない点を除き、下枠２２と同じ断面形状とされている。すなわち、上枠２１、縦枠２３、２４は同一断面形状とされている。 The upper frame 21 and the vertical frames 23 and 24 are different from each other in that the shapes of the upper rail 241 corresponding to the lower rail 242 in the lower frame 22 and the door contact portions 243 and 244 are different, and the lower surface of the outdoor end portion 222 of the lower frame 22. Is formed in the same cross-sectional shape as the lower frame 22 except that the upper frame 21 and the vertical frames 23 and 24 are not formed. That is, the upper frame 21 and the vertical frames 23 and 24 have the same cross-sectional shape.

下枠２２において、中骨２５および縦枠（第２縦枠）２４間は固定面材３が配置されるため、室外側に露出しない。一方、下枠２２において、中骨２５および縦枠（第１縦枠）２３間は固定面材３が配置されていない開口とされており、この部分が内障子４の室外側に露出する下枠室外露出面２０５とされている。
また、縦枠２４の見込み面は固定面材３が配置されるため室外側に露出しない。一方、縦枠２３の見込み面において、内障子４の室外側の部分は、図６に示すように、縦枠室外露出面２０６とされている。
すなわち、下枠室外露出面２０５は、下枠２２の室外見付け片部２１０の上面において装着溝２１１よりも室外側の面と、室外見付け片部２１０の室外面と、室外延出部２２１の上面とを備えて構成されている。
同様に、縦枠室外露出面２０６は、縦枠２３の室外見付け片部２１０の表面（見込み面）において装着溝２１１よりも室外側の面と、縦枠２３の室外見付け片部２１０の室外面と、室外延出部２２１の表面とを備えて構成されている。 In the lower frame 22, the fixed face material 3 is disposed between the middle bone 25 and the vertical frame (second vertical frame) 24, so that it is not exposed to the outdoor side. On the other hand, in the lower frame 22, an opening in which the fixed face material 3 is not disposed is formed between the middle bone 25 and the vertical frame (first vertical frame) 23, and this portion is exposed to the outside of the inner door 4. A frame outdoor exposure surface 205 is provided.
Moreover, since the fixed surface material 3 is arrange | positioned, the prospective surface of the vertical frame 24 is not exposed to the outdoor side. On the other hand, on the prospective surface of the vertical frame 23, the outdoor side portion of the inner shoji 4 is a vertical frame outdoor exposed surface 206 as shown in FIG. 6.
That is, the lower frame outdoor exposed surface 205 is a surface outside the mounting groove 211 on the upper surface of the outdoor finding piece portion 210 of the lower frame 22, the outdoor surface of the outdoor finding piece portion 210, and the upper surface of the outdoor extending portion 221. And is configured.
Similarly, the vertical frame outdoor exposed surface 206 includes a surface outside the mounting groove 211 on the surface (expected surface) of the outdoor finding piece 210 of the vertical frame 23 and an outdoor surface of the outdoor finding piece 210 of the vertical frame 23. And the surface of the outdoor extension part 221.

下枠２２および縦枠２３には、アルミニウムやステンレス等の金属製とされて、下枠室外露出面２０５および縦枠室外露出面２０６を覆う下枠用カバー材５０および縦枠用カバー材６０が取り付けられている。
下枠用カバー材５０は、図６、７にも示すように、前記縦枠２３に取り付けられた縦枠用カバー材６０と、中骨２５との間に配置されて下枠２２に取り付けられている。なお、下枠用カバー材５０の長さ寸法（下枠２２の長手方向に沿った寸法であり、片引き窓１の左右方向の寸法）は、縦枠用カバー材６０および中骨２５間の寸法に比べて僅かに小さくされている。これは、樹脂製の下枠２２と、金属製の下枠用カバー材５０とで線膨張係数が異なるため、熱による伸び量の違いを吸収できるようにするためである。このため、下枠用カバー材５０と中骨２５との間に隙間が生じるため、この隙間を隠すために、端部キャップ５３が配置されている。 The lower frame 22 and the vertical frame 23 are made of metal such as aluminum or stainless steel, and have a lower frame cover material 50 and a vertical frame cover material 60 that cover the lower frame outdoor exposed surface 205 and the vertical frame outdoor exposed surface 206. It is attached.
As shown in FIGS. 6 and 7, the lower frame cover member 50 is disposed between the vertical frame cover member 60 attached to the vertical frame 23 and the middle bone 25 and attached to the lower frame 22. ing. Note that the length dimension of the lower frame cover member 50 (the dimension along the longitudinal direction of the lower frame 22 and the horizontal dimension of the one-way window 1) is the dimension between the vertical frame cover member 60 and the middle bone 25. It is slightly smaller than This is because the resin lower frame 22 and the metal lower frame cover member 50 have different linear expansion coefficients, so that the difference in the amount of elongation due to heat can be absorbed. For this reason, since a gap is generated between the lower frame cover member 50 and the middle bone 25, an end cap 53 is arranged to hide the gap.

端部キャップ５３は、下枠用カバー材５０および中骨２５間に配置される本体板部５３１と、本体板部５３１の上面および室外面に取り付けられたカバー板部５３２、５３３とを備えている。本体板部５３１には、前記下枠用カバー材５０を支持する突起部５３４が形成されている。この突起部５３４は、下枠用カバー材５０が熱によって伸縮しても突起部５３４の上面から外れないような長さ寸法に設定されている。また、突起部５３４は、下枠用カバー材５０の端部に当接する面が傾斜面とされ、本体板部５３１に対して弾性変形可能に構成されている。このため、端部キャップ５３を、下枠用カバー材５０および中骨２５間の隙間に上方から押し込むと、突起部５３４の傾斜面が下枠用カバー材５０の端部に当接して突起部５３４が中骨２５側に弾性変形し、下枠用カバー材５０が突起部５３４の傾斜面を超えると、突起部５３４が元の状態に戻り、下枠用カバー材５０に係合する。これにより、端部キャップ５３を下枠用カバー材５０および中骨２５間に取り付けることができる。 The end cap 53 includes a main body plate portion 531 disposed between the lower frame cover member 50 and the middle bone 25, and cover plate portions 532 and 533 attached to the upper surface and the outdoor surface of the main body plate portion 531. Yes. The main body plate portion 531 is formed with a protruding portion 534 that supports the lower frame cover material 50. The projecting portion 534 is set to have such a length dimension that it does not come off from the upper surface of the projecting portion 534 even when the lower frame cover member 50 is expanded or contracted by heat. Further, the protrusion 534 is configured such that a surface that contacts the end of the lower frame cover member 50 is an inclined surface, and is elastically deformable with respect to the main body plate portion 531. For this reason, when the end cap 53 is pushed into the gap between the lower frame cover member 50 and the middle bone 25 from above, the inclined surface of the protrusion 534 comes into contact with the end of the lower frame cover member 50 and the protrusion When 534 is elastically deformed toward the middle bone 25 and the lower frame cover member 50 exceeds the inclined surface of the protrusion 534, the protrusion 534 returns to its original state and engages with the lower frame cover member 50. Thereby, the end cap 53 can be attached between the lower frame cover member 50 and the middle bone 25.

次に、下枠用カバー材５０および縦枠用カバー材６０について詳細に説明する。なお、各カバー材５０、６０は、ほぼ同じ構成であるため、下枠用カバー材５０を例に説明する。
下枠用カバー材５０は、図５に示すように、表面板部材５１と、立ち上がり部材５５との２部材で構成されている。
立ち上がり部材５５は、立ち上がり壁部５６と、係止片部５７とを備えて構成されている。
立ち上がり壁部５６は、下枠２２の見付け方向に沿って設けられ、その下端部は、取付片部２２６の角部（凸部）に係合する係合溝を有する係合部５６１と、係合部５６１から斜め下方に延出されたガイド部５６２とを備えている。立ち上がり壁部５６の上端部は、室内側に延出された突片部５６３を備えている。 Next, the lower frame cover member 50 and the vertical frame cover member 60 will be described in detail. Since the cover members 50 and 60 have substantially the same configuration, the cover material 50 for the lower frame will be described as an example.
As shown in FIG. 5, the lower frame cover member 50 includes two members, a surface plate member 51 and a rising member 55.
The rising member 55 includes a rising wall portion 56 and a locking piece portion 57.
The rising wall portion 56 is provided along the direction in which the lower frame 22 is found, and a lower end portion of the rising wall portion 56 includes an engagement portion 561 having an engagement groove that engages with a corner portion (convex portion) of the attachment piece portion 226. And a guide portion 562 extending obliquely downward from the joint portion 561. The upper end portion of the rising wall portion 56 includes a projecting piece portion 563 that extends to the indoor side.

係止片部５７は、立ち上がり壁部５６から室内側に突出した水平部５７１と、水平部５７１の先端から斜め下方に向かって延出された傾斜部５７２と、傾斜部５７２の下端から下方に向かって延出された鉛直部５７３と、鉛直部５７３の上下方向の中間部から室内側に突出された当接部５７４とを備えている。このため、鉛直部５７３の下端は、当接部５７４よりも下方に突出して形成されている。
当接部５７４の室内側先端には、斜め上方に延出されたガイド部５７５が形成されている。 The locking piece portion 57 includes a horizontal portion 571 that protrudes indoors from the rising wall portion 56, an inclined portion 572 that extends obliquely downward from the tip of the horizontal portion 571, and a lower portion from the lower end of the inclined portion 572. And a contact portion 574 that protrudes indoors from an intermediate portion in the vertical direction of the vertical portion 573. For this reason, the lower end of the vertical portion 573 is formed to protrude downward from the contact portion 574.
A guide portion 575 extending obliquely upward is formed at the indoor front end of the contact portion 574.

立ち上がり部材５５は、係合部５６１の係合溝が取付片部２２６の凸部に係合し、鉛直部５７３の室内面が見込み片部２２０の段差部２２４に当接している。この際、取付片部２２６の凸部と段差部２２４との間の寸法は、係合されていないフリー状態の立ち上がり部材５５における係合部５６１の溝部および鉛直部５７３の室内面間の寸法よりも小さな寸法に設定されている。このため、立ち上がり部材５５は、取付片部２２６および段差部２２４間にはめ込まれた状態では、立ち上がり壁部５６および係止片部５７が撓んで配置され、係合部５６１および鉛直部５７３が取付片部２２６および段差部２２４に付勢された状態で取り付けられている。
また、立ち上がり部材５５を取り付ける場合には、立ち上がり壁部５６のガイド部５６２が取付片部２２６に当接して係合部５６１が室内側に移動するように弾性変形するため、係合部５６１の取付片部２２６への係合をスムーズに行うことができる。 In the rising member 55, the engaging groove of the engaging portion 561 engages with the convex portion of the attachment piece portion 226, and the indoor surface of the vertical portion 573 is in contact with the step portion 224 of the prospective piece portion 220. At this time, the dimension between the convex part of the mounting piece part 226 and the step part 224 is based on the dimension between the groove part of the engaging part 561 and the indoor surface of the vertical part 573 in the free state rising member 55 which is not engaged. Even small dimensions are set. For this reason, when the rising member 55 is fitted between the mounting piece 226 and the stepped portion 224, the rising wall portion 56 and the locking piece portion 57 are bent and the engaging portion 561 and the vertical portion 573 are attached. It is attached in a state where it is urged by the piece portion 226 and the step portion 224.
When the rising member 55 is attached, the guide portion 562 of the rising wall portion 56 abuts against the attachment piece portion 226 and elastically deforms so that the engaging portion 561 moves to the indoor side. Engagement with the attachment piece 226 can be performed smoothly.

当接部５７４は、係合片部２２３と見込み片部２２０の上面との間の溝に差し込まれており、ガイド部５７５が係合片部２２３に当接することで、鉛直部５７３が上方に浮き上がることを防止している。したがって、鉛直部５７３が段差部２２４から外れることも防止できる。
したがって、立ち上がり壁部５６の係合部５６１、係止片部５７の鉛直部５７３、当接部５７４、ガイド部５７５によって、立ち上がり部材５５を下枠２２に係合する係合部が構成されている。 The contact portion 574 is inserted into a groove between the engagement piece portion 223 and the upper surface of the prospective piece portion 220, and the vertical portion 573 is moved upward by the guide portion 575 contacting the engagement piece portion 223. Prevents floating. Therefore, it is possible to prevent the vertical portion 573 from coming off the stepped portion 224.
Therefore, the engaging portion 561 of the rising wall portion 56, the vertical portion 573 of the locking piece portion 57, the contact portion 574, and the guide portion 575 constitute an engaging portion that engages the rising member 55 with the lower frame 22. Yes.

表面板部材５１は、平板状に形成された表面板部５１１と、表面板部５１１の室外側端縁部近傍の下面から突設された断面Ｌ字状の係合片部５１２と、表面板部５１１の室内側端部の近くの下面から突設されたフック部５１３とを備えている。
表面板部材５１と立ち上がり部材５５とは、係合片部５１２で形成される溝部に、立ち上がり壁部５６の突片部５６３を差し込むことで連結されている。
また、フック部５１３の折曲された凸部を、室外見付け片部２１０の突起２１２に係止することで、表面板部材５１は、スナップフィット式に室外見付け片部２１０に取り付けられる。
なお、表面板部材５１において、フック部５１３よりも室内側に延出された部分は、室外見付け片部２１０の上面に当接し、室外見付け片部２１０に取り付けられた気密材２６部分までを覆っている。
この際、表面板部５１１は、その表面が室内側から室外側に向かって低くなるように水勾配が付けられている。この水勾配は、２〜４度程度、例えば３度とされ、表面板部５１１上の雨水等をスムーズに室外側に排出できるように設定されている。 The surface plate member 51 includes a surface plate portion 511 formed in a flat plate shape, an engagement piece portion 512 having an L-shaped cross section protruding from the lower surface of the surface plate portion 511 in the vicinity of the outdoor edge, and a surface plate And a hook portion 513 protruding from the lower surface near the indoor side end portion of the portion 511.
The surface plate member 51 and the rising member 55 are connected by inserting the protruding piece portion 563 of the rising wall portion 56 into the groove portion formed by the engaging piece portion 512.
Further, the surface plate member 51 is attached to the outdoor finding piece portion 210 in a snap-fit manner by engaging the bent convex portion of the hook portion 513 with the protrusion 212 of the outdoor finding piece portion 210.
In the surface plate member 51, the portion extending to the indoor side from the hook portion 513 is in contact with the upper surface of the outdoor finding piece portion 210 and covers up to the portion of the airtight material 26 attached to the outdoor finding piece portion 210. ing.
At this time, the surface plate portion 511 is provided with a water gradient so that the surface thereof becomes lower from the indoor side toward the outdoor side. This water gradient is set to about 2 to 4 degrees, for example, 3 degrees, and is set so that rainwater or the like on the surface plate portion 511 can be smoothly discharged to the outdoor side.

縦枠用カバー材６０は、図６に示すように、表面板部材６１と、立ち上がり部材６５とを備えている。立ち上がり部材６５は、下枠用カバー材５０の立ち上がり部材５５と同一部品であるため、説明を省略する。
表面板部材６１は、表面に水勾配が形成されていない点を除き、下枠用カバー材５０の表面板部材５１と同じ構成であるため、説明を省略する。 As shown in FIG. 6, the vertical frame cover member 60 includes a surface plate member 61 and a rising member 65. Since the rising member 65 is the same component as the rising member 55 of the lower frame cover member 50, the description thereof is omitted.
Since the surface plate member 61 has the same configuration as the surface plate member 51 of the lower frame cover member 50 except that a water gradient is not formed on the surface, the description thereof is omitted.

下枠用カバー材５０は、表面板部材５１の室内側端部と、立ち上がり部材５５の下端部とで、下枠２２に接触しているが、その他の部分は下枠２２から離れて配置されている。このため、下枠用カバー材５０と下枠２２との間には、下枠側ホロー部（中空部）５９が形成されている。
縦枠用カバー材６０も、同様に、表面板部材６１の室内側端部と、立ち上がり部材６５の下端部とで縦枠２３に接触し、その他の部分は縦枠２３から離れて配置されている。このため、縦枠用カバー材６０と縦枠２３との間には、縦枠側ホロー部（中空部）６９が形成されている。 The lower frame cover member 50 is in contact with the lower frame 22 at the indoor side end portion of the surface plate member 51 and the lower end portion of the rising member 55, but the other portions are arranged away from the lower frame 22. ing. Therefore, a lower frame side hollow portion (hollow portion) 59 is formed between the lower frame cover member 50 and the lower frame 22.
Similarly, the vertical frame cover member 60 is in contact with the vertical frame 23 at the indoor side end portion of the surface plate member 61 and the lower end portion of the rising member 65, and other portions are arranged away from the vertical frame 23. Yes. Therefore, a vertical frame side hollow portion (hollow portion) 69 is formed between the vertical frame cover member 60 and the vertical frame 23.

また、縦枠用カバー材６０の表面板部材６１の見込み面は、縦枠２３の室外見付け片部２１０、室内見付け片部２３０、戸当り部２４３の見込み面とほぼ揃った位置に配置されている。このため、内障子４を開いた際に、縦枠２３および縦枠用カバー材６０の見込み面がほぼ直線状に揃って配置されて意匠性が向上する。 Further, the prospective surface of the surface plate member 61 of the vertical frame cover member 60 is arranged at a position substantially aligned with the prospective surfaces of the outdoor finding piece portion 210, the indoor finding piece portion 230, and the door stop portion 243 of the vertical frame 23. Yes. For this reason, when the inner shoji 4 is opened, the prospective surfaces of the vertical frame 23 and the vertical frame cover member 60 are arranged substantially in a straight line, so that the design is improved.

［網戸レール］
上枠２１および下枠２２には、スライド式の網戸７０を案内する網戸レール７１が取り付けられている。網戸レール７１は、アルミニウムやステンレス等の金属製のレールであり、図５に示すように、取付片部２２６にビス止めされる固定片部７１１と、固定片部７１１から網戸７０側に突出するレール部７１２と、固定片部７１１から室外端部２２２側に突出するカバー部７１３とを備えている。
レール部７１２の上端は、下枠用カバー材５０の上面や、室外見付け片部２１０、室内見付け片部２３０の上面とほぼ同じ高さ位置とされている。
カバー部７１３は、網戸レール７１を固定するビスが室外側に露出しないように、室外端部２２２と取付片部２２６との間の溝部の開口を覆っている。ただし、カバー部７１３と室外端部２２２との間には僅かな隙間が設定され、その隙間から排水可能に構成されている。 [Screen door rail]
A screen door rail 71 for guiding a sliding screen door 70 is attached to the upper frame 21 and the lower frame 22. The screen door rail 71 is a rail made of metal such as aluminum or stainless steel, and as shown in FIG. 5, a fixed piece portion 711 screwed to the attachment piece portion 226, and protrudes from the fixed piece portion 711 to the screen door 70 side. The rail part 712 and the cover part 713 which protrudes from the fixed piece part 711 to the outdoor end part 222 side are provided.
The upper end of the rail portion 712 is set at substantially the same height as the upper surface of the lower frame cover member 50 and the upper surfaces of the outdoor finding piece portion 210 and the indoor finding piece portion 230.
The cover part 713 covers the opening of the groove part between the outdoor end part 222 and the mounting piece part 226 so that the screw that fixes the screen door rail 71 is not exposed to the outdoor side. However, a slight gap is set between the cover portion 713 and the outdoor end portion 222, and drainage is possible from the gap.

縦枠２３および縦枠２４には、図４，６に示すように、室外端部２２２の室外面（見付け面）を被覆し、網戸７０の縦框が当接するカバー７５が取り付けられている。このカバー７５は、アルミニウムやステンレス等の金属製のカバーであり、縦枠２３、２４の取付片部２２６にビス止めされる固定片部７５１と、固定片部７５１から網戸７０側に突出する戸当り部７５２と、固定片部７５１から室外端部２２２側に突出するカバー部７５３とを備えている。
カバー部７５３は、室外端部２２２と取付片部２２６との間の溝部の開口から、室外端部２２２の室外面を覆い、さらに、室外端部２２２に沿って室内側に折曲され、その先端部は、室外端部２２２に形成された凹部に係合されている。 As shown in FIGS. 4 and 6, a cover 75 is attached to the vertical frame 23 and the vertical frame 24 so as to cover the outdoor surface (finding surface) of the outdoor end portion 222 and to which the vertical fence of the screen door 70 abuts. The cover 75 is a cover made of metal such as aluminum or stainless steel, a fixed piece 751 screwed to the attachment piece 226 of the vertical frames 23 and 24, and a door protruding from the fixed piece 751 to the screen door 70 side. A contact portion 752 and a cover portion 753 projecting from the fixed piece portion 751 toward the outdoor end portion 222 are provided.
The cover portion 753 covers the outdoor surface of the outdoor end portion 222 from the opening of the groove portion between the outdoor end portion 222 and the attachment piece portion 226, and is further bent to the indoor side along the outdoor end portion 222. The distal end is engaged with a recess formed in the outdoor end 222.

［排水経路］
下枠用カバー材５０で被覆された下枠２２の下枠室外露出面２０５は、内障子４の室外側に配置されるため、前記下枠側ホロー部５９には雨水が浸入する。また、縦枠用カバー材６０の表面に付着した水も、縦枠用カバー材６０から下枠２２の室外延出部２２１に流れる。このため、下枠２２の下枠側ホロー部５９に浸入した水を排水する経路が必要となる。
本実施形態では、下枠２２において室外延出部２２１の表面に係合片部２２３が形成され、室外端部２２２の表面に突出片部２２５、取付片部２２６が形成されている。そのため、係合片部２２３、突出片部２２５、取付片部２２６の一部を切り欠いて、排水経路としている。 [Drainage route]
Since the lower frame outdoor exposed surface 205 of the lower frame 22 covered with the lower frame cover member 50 is disposed outside the inner door 4, rainwater enters the lower frame side hollow portion 59. Further, water adhering to the surface of the vertical frame cover material 60 also flows from the vertical frame cover material 60 to the outdoor extension 221 of the lower frame 22. For this reason, a path for draining water that has entered the lower frame side hollow portion 59 of the lower frame 22 is required.
In the present embodiment, an engagement piece 223 is formed on the surface of the outdoor extension 221 in the lower frame 22, and a protruding piece 225 and an attachment piece 226 are formed on the surface of the outdoor end 222. Therefore, a part of the engagement piece 223, the protruding piece 225, and the attachment piece 226 is cut out to form a drainage path.

係合片部２２３は、図６，７にも示すように、縦枠２３側の端部と、中骨２５側の端部との２箇所に切欠部２２８が形成されて排水経路とされている。
また、突出片部２２５および取付片部２２６も２箇所に切欠部２２９が形成されて排水経路とされている。この切欠部２２９は、下枠２２の長手方向に沿った位置が、前記係合片部２２３の２つの切欠部２２８とは異なる位置に形成されている。
したがって、下枠側ホロー部５９に浸入した水は、係合片部２２３に沿って流れて左右いずれかの切欠部２２８から突出片部２２５側に流れ、さらに突出片部２２５に沿って流れた水は、切欠部２２９から網戸レール７１の下側の隙間を介して室外側に排出される。なお、本実施形態では、突出片部２２５、取付片部２２６によって、下枠２２の上面から突出して下枠２２の長手方向に連続する突出片が構成され、切欠部２２９によって突出片に形成された切欠部が構成されている。 As shown in FIGS. 6 and 7, the engagement piece portion 223 is formed with a notch 228 in two places, an end on the vertical frame 23 side and an end on the middle bone 25 side, and serves as a drainage path. Yes.
Further, the projecting piece 225 and the mounting piece 226 are also formed with a notch 229 at two places to form a drainage path. The notch 229 is formed at a position along the longitudinal direction of the lower frame 22 that is different from the two notches 228 of the engagement piece 223.
Accordingly, the water that has entered the lower frame side hollow portion 59 flows along the engaging piece portion 223, flows from the left or right cutout portion 228 to the protruding piece portion 225 side, and further flows along the protruding piece portion 225. Water is discharged from the notch 229 to the outdoor side through a gap below the screen door rail 71. In the present embodiment, the protruding piece portion 225 and the mounting piece portion 226 form a protruding piece that protrudes from the upper surface of the lower frame 22 and continues in the longitudinal direction of the lower frame 22, and is formed in the protruding piece by the notch portion 229. A notch is formed.

ここで、係合片部２２３に形成された切欠部２２８は、下枠用カバー材５０で覆われて隠されている。
突出片部２２５、取付片部２２６に形成された切欠部２２９は、網戸レール７１のカバー部７１３によって室外側から視認できないように隠されている。また、取付片部２２６の上面には、網戸レール７１の固定片部７１１が取り付けられており、固定片部７１１の室内側には下枠用カバー材５０が配置されて前記切欠部２２９が覆われているので、網戸レール７１のレール部７１２と、下枠用カバー材５０の立ち上がり部材５５との隙間からも前記切欠部２２９は視認できないように隠されている。 Here, the notch 228 formed in the engagement piece 223 is covered and hidden by the lower frame cover member 50.
The cutout portion 229 formed in the protruding piece portion 225 and the attachment piece portion 226 is hidden by the cover portion 713 of the screen door rail 71 so that it cannot be seen from the outdoor side. A fixed piece 711 of the screen door rail 71 is attached to the upper surface of the attachment piece 226, and a cover material 50 for the lower frame is disposed on the indoor side of the fixed piece 711 so as to cover the notch 229. Therefore, the notch 229 is also hidden from the gap between the rail portion 712 of the screen door rail 71 and the rising member 55 of the lower frame cover member 50 so as not to be visible.

［カバー材の取付手順］
以下、本実施形態に係る片引き窓１において、下枠用カバー材５０および縦枠用カバー材６０の取付手順について説明する。なお、縦枠用カバー材６０の取り付け手順は、下枠用カバー材５０と同一であるため、以下の説明では、下枠用カバー材５０の取り付け手順を例に説明する。
まず、立ち上がり部材５５を、下枠２２に取り付ける。すなわち、立ち上がり部材５５を室内側に傾けた状態で、ガイド部５７５および当接部５７４を係合片部２２３の溝部に差し込む。そして、当接部５７４を差し込んで、鉛直部５７３が段差部２２４に当接したら、立ち上がり部材５５を垂直方向に戻し、立ち上がり壁部５６のガイド部５６２を取付片部２２６に押し付け、係合部５６１を取付片部２２６の凸部に係合する。 [Installation procedure of cover material]
Hereinafter, the attachment procedure of the lower frame cover member 50 and the vertical frame cover member 60 in the single-drawing window 1 according to the present embodiment will be described. In addition, since the attachment procedure of the cover material 60 for vertical frames is the same as the cover material 50 for lower frames, the following description demonstrates the attachment procedure of the cover material 50 for lower frames as an example.
First, the rising member 55 is attached to the lower frame 22. That is, the guide portion 575 and the contact portion 574 are inserted into the groove portion of the engagement piece portion 223 with the rising member 55 inclined to the indoor side. When the abutting portion 574 is inserted and the vertical portion 573 comes into contact with the stepped portion 224, the rising member 55 is returned to the vertical direction, and the guide portion 562 of the rising wall portion 56 is pressed against the mounting piece portion 226 to engage the engaging portion. 561 is engaged with the convex portion of the mounting piece 226.

次に、図５の二点鎖線で示すように、立ち上がり部材５５の突片部５６３に、表面板部材５１の表面板部５１１と係合片部５１２間の溝を差し込む。そして、表面板部材５１のフック部５１３を室外見付け片部２１０の突起２１２に係合して取り付ける。これにより、下枠用カバー材５０を、ビスなどを用いることなく、スナップフィット式に下枠２２に取り付けることができる。
同様の手順で、縦枠用カバー材６０も縦枠２３に取り付けることができる。なお、本実施形態では、先に縦枠用カバー材６０を取り付けた後に、下枠用カバー材５０を取り付ける手順とされている。 Next, as shown by a two-dot chain line in FIG. 5, a groove between the surface plate portion 511 and the engagement piece portion 512 of the surface plate member 51 is inserted into the protruding piece portion 563 of the rising member 55. Then, the hook portion 513 of the surface plate member 51 is engaged with and attached to the protrusion 212 of the outdoor finding piece portion 210. Thereby, the cover material 50 for lower frames can be attached to the lower frame 22 in a snap-fit manner without using screws or the like.
The vertical frame cover member 60 can also be attached to the vertical frame 23 in the same procedure. In this embodiment, the cover material 50 for the lower frame is attached after the cover material 60 for the vertical frame is attached first.

以上により、下枠２２の下枠室外露出面２０５が下枠用カバー材５０で覆われ、縦枠２３の縦枠室外露出面２０６が縦枠用カバー材６０で覆われる。また、下枠用カバー材５０、縦枠用カバー材６０で覆われていない取付片部２２６の部分は、網戸レール７１およびカバー７５によって覆われる。 As described above, the lower frame outdoor exposed surface 205 of the lower frame 22 is covered with the lower frame cover material 50, and the vertical frame outdoor exposed surface 206 of the vertical frame 23 is covered with the vertical frame cover material 60. The portion of the attachment piece 226 that is not covered with the lower frame cover member 50 and the vertical frame cover member 60 is covered with the screen door rail 71 and the cover 75.

［本実施形態の効果］
（１）本実施形態では、内障子４の室外側に露出する下枠２２の下枠室外露出面２０５と、縦枠２３の縦枠室外露出面２０６とを、下枠用カバー材５０および縦枠用カバー材６０で被覆しているので、太陽光が下枠室外露出面２０５や縦枠室外露出面２０６に到達することを防止できる。このため、樹脂枠である下枠２２や縦枠２３の表面温度が上昇することも防止でき、樹脂枠の熱変形等の影響を軽減できる。
さらに、金属製の網戸レール７１やカバー７５を取り付けているので、下枠用カバー材５０や縦枠用カバー材６０で覆われていない取付片部２２６や、縦枠２３の室外端部２２２の室外面に太陽光が照射することを防止でき、この点でも樹脂枠の熱変形などの影響をより軽減できる。
また、気温が低い場合に、樹脂製の窓枠２に衝撃が加わると、割れや破損が生じる虞がある。特に、下枠２２や縦枠２３は、内障子４を開いて開口を出入りする際に、物を落とすことなどで衝撃が加わり、破損する可能性がある。本実施形態では、下枠２２や縦枠２３の室外露出面２０５，２０６を、金属製の下枠用カバー材５０、縦枠用カバー材６０で覆って保護しているため、物を落としたりしても、下枠２２や縦枠２３が破損することを防止できる。 [Effect of this embodiment]
(1) In the present embodiment, the lower frame outdoor exposed surface 205 of the lower frame 22 exposed to the outdoor side of the inner shoji 4 and the vertical frame outdoor exposed surface 206 of the vertical frame 23 are connected to the lower frame cover member 50 and the vertical frame cover material 50. Since it is covered with the frame cover material 60, it is possible to prevent sunlight from reaching the lower frame outdoor exposed surface 205 and the vertical frame outdoor exposed surface 206. For this reason, it can also prevent that the surface temperature of the lower frame 22 and the vertical frame 23 which are resin frames rises, and can reduce the influence of a thermal deformation etc. of a resin frame.
Further, since the metal screen door rail 71 and the cover 75 are attached, the attachment piece 226 not covered with the lower frame cover material 50 and the vertical frame cover material 60 and the outdoor end 222 of the vertical frame 23 It is possible to prevent the outdoor surface from being irradiated with sunlight, and also in this respect, the influence of thermal deformation of the resin frame can be further reduced.
In addition, when the temperature is low and an impact is applied to the resin window frame 2, there is a possibility that cracking or breakage may occur. In particular, the lower frame 22 and the vertical frame 23 may be damaged by dropping an object or the like when the inner sliding element 4 is opened to enter or leave the opening. In this embodiment, the outdoor exposed surfaces 205 and 206 of the lower frame 22 and the vertical frame 23 are covered and protected by the metal lower frame cover material 50 and the vertical frame cover material 60, so that objects can be dropped. Even so, it is possible to prevent the lower frame 22 and the vertical frame 23 from being damaged.

（２）下枠２２と下枠用カバー材５０との間には下枠側ホロー部５９が形成され、縦枠２３と縦枠用カバー材６０との間には縦枠側ホロー部６９が形成されている。このため、下枠用カバー材５０および縦枠用カバー材６０を、下枠２２および縦枠２３から離間して配置でき、金属製のカバー材５０，６０から下枠２２、縦枠２３に熱が伝わることを抑制できる。したがって、下枠２２、縦枠２３の熱変形をさらに抑制できる。 (2) A lower frame side hollow portion 59 is formed between the lower frame 22 and the lower frame cover member 50, and a vertical frame side hollow portion 69 is formed between the vertical frame 23 and the vertical frame cover member 60. Is formed. For this reason, the lower frame cover material 50 and the vertical frame cover material 60 can be arranged apart from the lower frame 22 and the vertical frame 23, and heat is applied from the metal cover materials 50, 60 to the lower frame 22 and the vertical frame 23. Can be suppressed. Therefore, the thermal deformation of the lower frame 22 and the vertical frame 23 can be further suppressed.

（３）下枠用カバー材５０の上面（表面板部材５１の表面）と、下枠２２の室内見付け片部２３０、下レール２４２、室外見付け片部２１０の各上面と、網戸レール７１の上面との高さ位置を同じ高さに設定しているので、下枠２２、下枠用カバー材５０、網戸レール７１の上面をほぼフラットな状態にできる。このため、下枠２２の上面を車椅子で移動でき、バリアフリー対応の片引き窓１とすることができる。 (3) The upper surface of the lower frame cover member 50 (the surface of the surface plate member 51), the upper surfaces of the indoor finding piece 230, the lower rail 242, and the outdoor finding piece 210 of the lower frame 22, and the upper surface of the screen door rail 71 Therefore, the upper surface of the lower frame 22, the lower frame cover member 50, and the screen door rail 71 can be made almost flat. For this reason, the upper surface of the lower frame 22 can be moved with a wheelchair, and the barrier-free compatible sliding window 1 can be obtained.

（４）下枠用カバー材５０および網戸レール７１の上面と、下枠２２の上面とがほぼ揃っており、縦枠用カバー材６０およびカバー７５の見込み面と、縦枠２３の見込み面とがほぼ揃っているため、下枠２２および縦枠２３の見込み面をほぼフラットでシンプルな意匠にでき、外観を向上できる。
その上、下枠２２や縦枠２３の係合片部２２３、段差部２２４、突出片部２２５、取付片部２２６等を、下枠用カバー材５０、縦枠用カバー材６０、網戸レール７１、カバー７５で隠すことができ、この点でも意匠性を向上できる。特に、下枠２２の係合片部２２３や、突出片部２２５、取付片部２２６には、排水経路用の切欠部２２８、２２９を形成しているが、これらの切欠部２２８、２２９も下枠用カバー材５０や網戸レール７１で隠すことができ、意匠性を向上できる。 (4) The upper surface of the lower frame cover material 50 and the screen door rail 71 and the upper surface of the lower frame 22 are substantially aligned, the expected surface of the vertical frame cover material 60 and the cover 75, and the expected surface of the vertical frame 23. Therefore, the prospective surfaces of the lower frame 22 and the vertical frame 23 can be made into a substantially flat and simple design, and the appearance can be improved.
In addition, the engaging piece 223, the stepped portion 224, the protruding piece 225, the mounting piece 226, and the like of the lower frame 22 and the vertical frame 23 are attached to the lower frame cover material 50, the vertical frame cover material 60, and the screen door rail 71. The cover 75 can be hidden, and the design can be improved in this respect. In particular, the engagement piece portion 223, the protruding piece portion 225, and the attachment piece portion 226 of the lower frame 22 are formed with notch portions 228 and 229 for drainage passages. It can be hidden by the frame cover material 50 or the screen door rail 71, and the design can be improved.

（５）下枠用カバー材５０および縦枠用カバー材６０は、下枠２２や縦枠２３にスナップフィット式に取り付けられるので、ビス等で固定する場合に比べて、容易に取り付けることができる。さらに、取り外しも容易であるため、カバー材５０、６０が変形・破損した場合でも容易に交換できる。
その上、各カバー材５０、６０は、表面板部材５１、６１と、立ち上がり部材５５、６５との２つの部材で構成しているので、これらが一体に形成されている場合に比べて、カバー材５０、６０の着脱作業を容易に行うことができる。例えば、表面板部材５１、６１が立ち上がり部材５５、６５と別体であれば、当接部５７４を係合片部２２３の溝部に差し込む場合などに視認しながら作業でき、各カバー材５０、６０を下枠２２、縦枠２３に取り付ける作業や取り外す作業を容易に行うことができる。 (5) Since the lower frame cover material 50 and the vertical frame cover material 60 are attached to the lower frame 22 and the vertical frame 23 in a snap-fit manner, they can be easily attached as compared to the case of fixing with screws or the like. . Furthermore, since it is easy to remove, the cover members 50 and 60 can be easily replaced even when they are deformed or damaged.
In addition, the cover members 50 and 60 are composed of two members, that is, the surface plate members 51 and 61 and the rising members 55 and 65. The attachment and detachment work of the materials 50 and 60 can be easily performed. For example, if the surface plate members 51 and 61 are separate from the rising members 55 and 65, the work can be performed while visually recognizing when the contact portion 574 is inserted into the groove portion of the engagement piece portion 223. Can be easily attached to and removed from the lower frame 22 and the vertical frame 23.

（６）下枠用カバー材５０、縦枠用カバー材６０において、立ち上がり部材５５、６５は同一部品を兼用できるため、部品種類を少なくできる。また、表面板部材５１、６１は、水勾配の有無のみが相違するため、容易に製造できる。 (6) In the lower frame cover material 50 and the vertical frame cover material 60, since the rising members 55 and 65 can also use the same component, the number of components can be reduced. Moreover, since the surface plate members 51 and 61 differ only in the presence or absence of a water gradient, they can be easily manufactured.

（７）網戸レール７１やカバー７５が、上枠２１、下枠２２、縦枠２３、２４とは別体のアタッチメント式であるため、網戸７０の種類に応じて交換することができる。したがって、スライド網戸や上げ下げ網戸、ロール網戸など、様々な種類の網戸を利用することができる。
さらに、網戸レール７１、カバー７５は、金属製であるため、樹脂製の断面が細い形状の網戸レールを用いる場合に比べて、剛性を向上できて、破損や変形の発生を抑制できる。 (7) Since the screen door rail 71 and the cover 75 are an attachment type separate from the upper frame 21, the lower frame 22, and the vertical frames 23, 24, they can be exchanged according to the type of the screen door 70. Therefore, various types of screen doors such as a sliding screen door, a lifting screen door, and a roll screen door can be used.
Furthermore, since the screen door rail 71 and the cover 75 are made of metal, the rigidity can be improved and the occurrence of breakage and deformation can be suppressed as compared with the case where a screen door rail having a thin resin cross section is used.

（８）下枠用カバー材５０と中骨２５との間にクリアランスを確保し、その隙間を端部キャップ５３で隠しているので、下枠用カバー材５０と下枠２２との熱伸縮量が異なるために、下枠用カバー材５０が中骨２５に押し付けられることも防止できる。 (8) Since a clearance is secured between the lower frame cover member 50 and the middle bone 25 and the gap is hidden by the end cap 53, the amount of thermal expansion and contraction between the lower frame cover member 50 and the lower frame 22 Therefore, it is possible to prevent the lower frame cover member 50 from being pressed against the middle bone 25.

［変形例］
本発明は、以上の実施形態で説明した構成のものに限定されず、本発明の目的を達成できる範囲での変形例は、本発明に含まれる。
例えば、前記実施形態では、下枠用カバー材５０や網戸レール７１の上面を、室外見付け片部２１０、室内見付け片部２３０、下レール２４２の上面とほぼ同じ高さとして下枠２２のフラット化を実現しているが、バリアフリーが要求されない場合には、下枠用カバー材５０の上面高さを、下枠２２の上面と異ならせてもよい。同様に、縦枠用カバー材６０の見込み面と、縦枠２３の見込み面とを揃えなくてもよい。 [Modification]
The present invention is not limited to the configuration described in the above embodiment, and modifications within a range in which the object of the present invention can be achieved are included in the present invention.
For example, in the embodiment, the lower frame 22 is flattened so that the upper surfaces of the lower frame cover member 50 and the screen rail 71 are substantially the same height as the upper surfaces of the outdoor finding piece 210, the indoor finding piece 230, and the lower rail 242. However, when barrier-free is not required, the upper surface height of the lower frame cover member 50 may be different from the upper surface of the lower frame 22. Similarly, the prospective surface of the vertical frame cover member 60 and the prospective surface of the vertical frame 23 may not be aligned.

前記実施形態では、下枠用カバー材５０と下枠２２との間に下枠側ホロー部５９を形成し、縦枠用カバー材６０と縦枠２３との間に縦枠側ホロー部６９を形成していたが、下枠用カバー材５０や縦枠用カバー材６０を下枠２２や縦枠２３に密着させてホロー部を形成しなくてもよい。
カバー７５と同様に、網戸レール７１のカバー部７１３を延長して、上枠２１や下枠２２の室外端部２２２の室外面を被覆してもよい。 In the embodiment, the lower frame side hollow portion 59 is formed between the lower frame cover member 50 and the lower frame 22, and the vertical frame side hollow portion 69 is interposed between the vertical frame cover member 60 and the vertical frame 23. Although the lower frame cover material 50 and the vertical frame cover material 60 are in close contact with the lower frame 22 and the vertical frame 23, the hollow portion may not be formed.
Similarly to the cover 75, the cover portion 713 of the screen door rail 71 may be extended to cover the outdoor surfaces of the outdoor end portions 222 of the upper frame 21 and the lower frame 22.

本発明において、下枠用カバー材５０が下枠２２の上面における下枠室外露出面２０５を被覆するとは、表面温度が上昇しやすく熱変形等の影響を受けやすい部分や、落下物が衝突しやすい部分を覆うことを意味する。したがって、下枠用カバー材５０は、下枠室外露出面２０５の全面を覆うものに限らない。すなわち、下枠用カバー材５０は、下枠２２の表面温度の上昇を抑制して熱変形等の影響を軽減したり、落下物等が直接下枠２２に衝突しないように保護できればよいため、前記熱変形等の影響を受けにくい部分や、落下物が衝突するおそれが無い部分は覆わずに、熱変形等の影響を受けやすい部分や落下物が衝突するおそれがある部分のみを覆うものでもよい。
同様に、縦枠用カバー材６０が縦枠２３の見込み面における縦枠室外露出面２０６を被覆するとは、少なくとも熱変形等の影響を受けやすい部分や、物が衝突しやすい部分を覆うことを意味する。したがって、縦枠２３の縦枠室外露出面２０６を覆う縦枠用カバー材６０も、縦枠室外露出面２０６の全面を覆うものに限らず、縦枠室外露出面２０６の一部を残して覆うものでもよい。 In the present invention, when the lower frame cover member 50 covers the lower frame outdoor exposed surface 205 on the upper surface of the lower frame 22, the surface temperature is likely to rise, and a portion that is easily affected by thermal deformation or a falling object collides. It means covering easy parts. Therefore, the lower frame cover member 50 is not limited to covering the entire lower frame outdoor exposed surface 205. That is, the lower frame cover material 50 only needs to suppress the increase in the surface temperature of the lower frame 22 to reduce the influence of thermal deformation or the like, or to protect the fallen object from directly colliding with the lower frame 22. Even if it covers only parts that are not easily affected by thermal deformation, etc., parts that are not likely to collide with falling objects, and parts that are susceptible to thermal deformation, etc. Good.
Similarly, covering the vertical frame outdoor exposed surface 206 on the prospective surface of the vertical frame 23 with the vertical frame cover material 60 covers at least a portion that is susceptible to thermal deformation or a portion that is likely to collide with an object. means. Therefore, the vertical frame cover material 60 covering the vertical frame outdoor exposed surface 206 of the vertical frame 23 is not limited to covering the entire surface of the vertical frame outdoor exposed surface 206, but covers a part of the vertical frame outdoor exposed surface 206. It may be a thing.

下枠用カバー材５０や縦枠用カバー材６０は、表面板部材５１、６１および立ち上がり部材５５、６５が別体とされたものに限定されず、これらが一体に形成されたカバー材でもよい。また、下枠用カバー材５０や縦枠用カバー材６０の下枠２２や縦枠２３への取付構造は、前記実施形態に限定されない。
また、本発明は、前記実施形態の片引き窓１に限定されず、両袖片引き窓にも適用可能である。 The cover material 50 for the lower frame and the cover material 60 for the vertical frame are not limited to those in which the surface plate members 51 and 61 and the rising members 55 and 65 are separated, and may be a cover material in which these are integrally formed. . Moreover, the attachment structure to the lower frame 22 and the vertical frame 23 of the cover material 50 for lower frames and the cover material 60 for vertical frames is not limited to the said embodiment.
Further, the present invention is not limited to the single sliding window 1 of the above-described embodiment, but can be applied to a double sleeve single sliding window.
