Description

本発明は樹脂材からなる枠体内に引き違い状の障子を納めてなる樹脂サッシに関し、特に下枠の敷居面について平坦な面の大きさを選択できる樹脂サッシに関する。 The present invention relates to a resin sash in which a sliding shoji is housed in a frame made of a resin material, and particularly to a resin sash capable of selecting a flat surface size for a sill surface of a lower frame.

従来から、枠体内に引き違い状の障子を納めてなるサッシにおいて、枠体及び障子を樹脂材で構成し、しかも下枠のレールの高さを揃えて敷居面を略フラットに形成した樹脂サッシが知られている。このような樹脂サッシとしては、例えば特許文献１に挙げるようなものがある。樹脂サッシの場合、上下枠及び左右の縦枠の各両端部を斜めに切断し、それらを突き合わせ溶着することで方形状の枠体を構成するようにすることがある。このように突き合わせて溶着をするためには、枠体を構成する上下枠及び左右の縦枠は断面形状が略同じとなるように形成する必要がある。
特開平１０−１１５１５２号公報 Conventionally, in a sash in which a sliding shoji is housed in a frame, the frame and shoji are made of a resin material, and the height of the rail of the lower frame is aligned to form a sill surface substantially flat. It has been known. Examples of such a resin sash include those described in Patent Document 1. In the case of a resin sash, a rectangular frame may be formed by obliquely cutting both end portions of the upper and lower frames and the left and right vertical frames and then butting them together. In order to perform welding in such a manner, the upper and lower frames and the left and right vertical frames constituting the frame body need to be formed so as to have substantially the same cross-sectional shape.
JP-A-10-115152

従来の樹脂サッシでは、敷居面における平坦な面が大きい下枠フラットサッシとするために、レール間に上面がレールと略同じ高さであるアタッチメントを設ける場合がある。このように平坦な面が大きい下枠フラットサッシには、アタッチメントを取付けるためレール間の凹部に突出状に形成した基部を設けて、この基部に対してアタッチメントを係合ないし嵌合させて固定するようにしている。 In the conventional resin sash, an attachment having an upper surface that is substantially the same height as the rail may be provided between the rails in order to obtain a lower frame flat sash having a large flat surface on the sill surface. In such a lower flat sash having a large flat surface, a base formed in a protruding shape is provided in the recess between the rails to attach the attachment, and the attachment is engaged or fitted to the base to be fixed. I am doing so.

一方で、コストダウンのためにアタッチメントを取付けることなくレールだけで敷居面を構成する場合もある。この場合にはレール間の凹部を平面のみで構成し、基部など突出する部分を設けないようにしていた。すなわち、アタッチメントを取付けて平坦な面を大きくした下枠フラットサッシと、アタッチメントを設けず敷居面をレールのみで構成した通常の樹脂サッシとでは、枠の形状が異なっており、相互に共用化することができなかった。そのため、コストの増大を招いていた。 On the other hand, there is a case where the sill surface is constituted only by rails without attaching an attachment for cost reduction. In this case, the concave portion between the rails is constituted only by a flat surface, and no protruding portion such as a base portion is provided. That is, the frame shape of the lower frame flat sash with the attachment attached and the flat surface enlarged, and the ordinary resin sash with the sill surface made up of only rails without attachments, are mutually shared. I couldn't. Therefore, the cost has been increased.

本発明の実施形態について図面に沿って詳細に説明する。図１は本実施形態における枠体及び障子の組み合わせを示した図である。本実施形態におけるサッシの基本構成は、建物開口部に取付けられる枠体１内に、外障子４と内障子５を引き違い状に納め、さらにその室外側には網戸６を納めてなるものである。枠体１は樹脂材からなり、下枠１０と上枠２０及び左右の縦枠３０、３０を方形状に枠組みして構成されるものである。また、外障子４と内障子５は、樹脂材からなる下框４０と上框５０及び左右の縦框６０、６０を方形状に框組みして框体２を構成し、その内部にガラス体３を納めてなるものである。 Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a view showing a combination of a frame and a shoji in this embodiment. The basic structure of the sash in this embodiment is that the outer shoji 4 and the inner shoji 5 are accommodated in the frame 1 attached to the building opening, and the screen door 6 is accommodated outside the outdoor door. is there. The frame 1 is made of a resin material, and is configured by a lower frame 10, an upper frame 20, and left and right vertical frames 30, 30 being framed in a square shape. The outer shoji 4 and the inner shoji 5 are composed of a lower rod 40, an upper rod 50, and left and right vertical rods 60, 60 made of a resin material in a square shape to form a frame 2, and a glass body inside thereof. 3 will be included.

図１（Ａ）及び図１（Ｂ）には、下枠１０と下框４０の組み合わせ部分を示している。図１（Ａ）には基本フラット枠体を示している。その下枠１０は、樹脂材からなり、下部には中空状に形成されてなる中空部１１を有し、その上部には敷居面１２が形成されている。敷居面１２には、室外側から順にそれぞれ突出状の網戸レール部１２ａ、外レール部１２ｂ、内レール部１２ｃ、及び室内側部１２ｄが形成されている。これら外レール１２ｂ、内レール部１２ｃ、及び室内側部１２ｄの上面は、略同じ高さとなるように形成されている。 1A and 1B show a combined portion of the lower frame 10 and the lower eyelid 40. FIG. FIG. 1A shows a basic flat frame. The lower frame 10 is made of a resin material, has a hollow portion 11 formed in a hollow shape at the lower portion, and a sill surface 12 is formed at the upper portion. On the sill surface 12, a protruding screen door rail portion 12a, an outer rail portion 12b, an inner rail portion 12c, and an indoor side portion 12d are formed in order from the outdoor side. The upper surfaces of the outer rail 12b, the inner rail portion 12c, and the indoor side portion 12d are formed to have substantially the same height.

網戸レール部１２ａと外レール部１２ｂにより外側凹部１３が、外レール部１２ｂと内レール部１２ｃにより中間凹部１４が、内レール部１２ｃと室内側部１２ｄにより内側凹部１５が、それぞれ形成されている。上枠２０と縦枠３０についても、略同じ断面形状を有するように形成される。 The outer recess 13 is formed by the screen door rail portion 12a and the outer rail portion 12b, the intermediate recess portion 14 is formed by the outer rail portion 12b and the inner rail portion 12c, and the inner recess portion 15 is formed by the inner rail portion 12c and the indoor side portion 12d. . The upper frame 20 and the vertical frame 30 are also formed to have substantially the same cross-sectional shape.

また、下枠１０の網戸レール部１２ａには、網戸レールカバー８０が取付けられる。網戸レールカバー８０は、外側凹部１３の室外面と底面を略覆う板状に形成され、上面には網戸６を案内する網戸レール８１が形成されている。この網戸レール８１の上端は外レール部１２ｂや内レール部１２ｃの上面と略同じ高さとなるように形成されている。 A screen door rail cover 80 is attached to the screen door rail portion 12 a of the lower frame 10. The screen door rail cover 80 is formed in a plate shape that substantially covers the outdoor surface and bottom surface of the outer recess 13, and a screen door rail 81 that guides the screen door 6 is formed on the top surface. The upper end of the screen door rail 81 is formed to have substantially the same height as the upper surfaces of the outer rail portion 12b and the inner rail portion 12c.

図１（Ｂ）には拡張フラット枠体を示している。その下枠１０は、図１（Ａ）に示す基本フラット枠体の下枠１０に対して、中間凹部１４には外側アタッチメント７０を、内側凹部１５には内側アタッチメント７５を、それぞれ取付けてなるものである。外側アタッチメント７０及び内側アタッチメント７５の上面は、いずれも各レール部の上面と略同じ高さとなるように形成されており、したがって図１（Ｂ）に示す下枠は、図１（Ａ）に示す下枠よりも、略フラットな平面部分が広くなる。 FIG. 1B shows an extended flat frame. The lower frame 10 is constructed by attaching an outer attachment 70 to the intermediate recess 14 and an inner attachment 75 to the inner recess 15 with respect to the lower frame 10 of the basic flat frame shown in FIG. It is. The upper surfaces of the outer attachment 70 and the inner attachment 75 are both formed so as to be substantially the same height as the upper surface of each rail portion. Therefore, the lower frame shown in FIG. 1 (B) is shown in FIG. 1 (A). The substantially flat plane portion is wider than the lower frame.

また、下枠１０の網戸レール部１２ａには、基本フラット枠体の場合とは異なる網戸レールカバー８０が取付けられる。この場合の網戸レールカバー８０は、外側凹部１３の室外面と底面を覆う点では基本フラット枠体に取付けられるものと同様であるが、外側凹部１３の室外面を覆う部分については中空状に形成され、その上面には平坦部８４を有している。すなわち、拡張フラット枠体に取付けられる網戸レールカバー８０によっても、下枠１０の敷居面１２における略フラットな平面部分を広くしている。 Further, a screen door rail cover 80 different from the case of the basic flat frame body is attached to the screen door rail portion 12a of the lower frame 10. The screen rail cover 80 in this case is the same as that attached to the basic flat frame in that it covers the outdoor surface and bottom surface of the outer recess 13, but the portion covering the outdoor surface of the outer recess 13 is formed in a hollow shape. The upper surface has a flat portion 84. That is, the substantially flat plane portion in the sill surface 12 of the lower frame 10 is also widened by the screen door rail cover 80 attached to the extended flat frame body.

このように２種類の枠体１について、基本フラット枠体を共用し、下枠１０に対するアタッチメント取付けの有無により略フラットな平面部分の大きさを異なるものとしている。このため、基本フラット枠体の下枠１０には、アタッチメントの取付部が形成されている。ただし、図１（Ａ）のようにアタッチメントを取付けることなく基本フラット枠体のみで用いる場合もあるため、下枠１０を構成する面とアタッチメントを構成する面とを互いに当接させ、その当接面でネジないしビス止めまたは嵌合により面固定がなされるようにしている。すなわち、下枠１０にアタッチメント取付けのための突出部分を設けないようにしている。 As described above, the basic flat frame body is shared for the two types of frame bodies 1, and the size of the substantially flat plane portion is different depending on whether or not the attachment is attached to the lower frame 10. For this reason, the attachment part of an attachment is formed in the lower frame 10 of the basic flat frame. However, as shown in FIG. 1A, there is a case where only the basic flat frame body is used without attaching an attachment. Therefore, the surface constituting the lower frame 10 and the surface constituting the attachment are brought into contact with each other, and the contact is made. The surface is fixed by screws or screws or fitting on the surface. In other words, the lower frame 10 is not provided with a protruding portion for attaching the attachment.

基本フラット枠体と拡張フラット枠体では、内部に納める障子の形状が異なっている。図１（Ａ）に示すように、基本フラット枠体に納める外障子４の下框４０は、室外面を垂下した室外垂下部４１と、室内面を垂下した室内垂下部４２とを有し、室外垂下部４１は下枠１０の外側凹部１３に、室内垂下部４２は下枠１０の中間凹部１４に、それぞれ納められる。また、内障子５の下框４０も、室外面を垂下した室外垂下部４１と、室内面を垂下した室内垂下部４２とを有し、室外垂下部４１は下枠１０の中間凹部１４に、室内垂下部４２は下枠１０の内側凹部１５に、それぞれ納められる。すなわち、基本フラット枠体を選択した場合、障子は両側垂下障子であって下框４０の室内外垂下部により下枠１０のレール部を跨ぐように配置される。 The basic flat frame and the extended flat frame are different in the shape of the shoji that can be accommodated inside. As shown in FIG. 1 (A), the lower arm 40 of the outer panel 4 to be stored in the basic flat frame has an outdoor hanging portion 41 that hangs down the outdoor surface, and an indoor hanging portion 42 that hangs down the indoor surface, The outdoor hanging part 41 is housed in the outer recessed part 13 of the lower frame 10, and the indoor hanging part 42 is housed in the intermediate recessed part 14 of the lower frame 10. In addition, the lower arm 40 of the inner shoji 5 also has an outdoor hanging portion 41 that hangs down the outdoor surface and an indoor hanging portion 42 that hangs down the indoor surface, and the outdoor hanging portion 41 is formed in the intermediate recess 14 of the lower frame 10. The indoor hanging parts 42 are respectively stored in the inner recesses 15 of the lower frame 10. That is, when the basic flat frame is selected, the shoji is a double-sided shoji and is arranged so as to straddle the rail portion of the lower frame 10 by the indoor and outdoor hanging portions of the lower arm 40.

図１（Ｂ）に示すように、拡張フラット枠体に納める外障子４の下框４０は、室外面を垂下した室外垂下部４１を有し、室内面については垂下されずに室内下端部４３を構成する。室外垂下部４１は下枠１０の外側凹部１３に納められ、室内下端部４３は下面が外側アタッチメント７０の上面に対向する。また、内障子５の下框４０も、室外面を垂下した室外垂下部４１を有し、室内面については垂下されずに室内下端部４３を構成する。室外垂下部４１は下枠１０の中間凹部１４に納められ、室内下端部４３は下面が内側アタッチメント７５の上面に対向する。すなわち、拡張フラット枠体を選択した場合、障子は片側垂下障子であって下框４０の室外垂下部が下枠１０の凹部に飲み込まれるように配置される。 As shown in FIG. 1 (B), the lower arm 40 of the external shoji 4 to be accommodated in the extended flat frame has an outdoor hanging portion 41 that hangs down the outdoor surface, and the indoor lower surface 43 does not hang down on the indoor surface. Configure. The outdoor hanging portion 41 is housed in the outer recessed portion 13 of the lower frame 10, and the lower surface of the indoor lower end portion 43 is opposed to the upper surface of the outer attachment 70. Further, the lower arm 40 of the inner shoji 5 also has an outdoor hanging portion 41 that hangs down the outdoor surface, and constitutes the indoor lower end portion 43 without hanging down on the indoor surface. The outdoor hanging portion 41 is housed in the intermediate recess 14 of the lower frame 10, and the lower surface of the indoor lower end portion 43 is opposed to the upper surface of the inner attachment 75. That is, when the extended flat frame is selected, the shoji is a one-sided shoji and is arranged so that the outdoor hanging portion of the lower arm 40 is swallowed by the recess of the lower frame 10.

次に、それぞれのサッシについてより詳細に説明する。まず、基本フラット枠体を選択した場合のサッシについて説明する。図２には基本フラット枠体を用いたサッシの縦断面図を、図３には基本フラット枠体を用いたサッシの横断面図を示している。これら各図に示すように、枠体１を構成する下枠１０と上枠２０及び左右の縦枠３０、３０は略同じ断面形状を有している。また、框体２を構成する下框４０と上框５０及び左右の縦框６０、６０についても、略同じ断面形状を有している。 Next, each sash will be described in more detail. First, the sash when the basic flat frame is selected will be described. FIG. 2 is a longitudinal sectional view of a sash using the basic flat frame body, and FIG. 3 is a transverse sectional view of the sash using the basic flat frame body. As shown in these drawings, the lower frame 10 and the upper frame 20 and the left and right vertical frames 30 and 30 constituting the frame 1 have substantially the same cross-sectional shape. Further, the lower rod 40, the upper rod 50, and the left and right vertical rods 60, 60 constituting the housing 2 have substantially the same cross-sectional shape.

基本フラット枠体の下枠１０について説明する。図４には、下枠１０の拡大図を示している。上述のように、下枠１０の上部には室外側から順に網戸レール部１２ａ、外レール部１２ｂ、内レール部１２ｃ、及び室内側部１２ｄが形成されている。外レール部１２ｂと内レール部１２ｃは、上面がそれぞれ外レール及び内レールとして形成されており、これらに下框４０下部に設けられる戸車４５が載置され、外障子４及び内障子５を長手方向に走行自在としている。 The lower frame 10 of the basic flat frame will be described. FIG. 4 shows an enlarged view of the lower frame 10. As described above, the screen door rail portion 12a, the outer rail portion 12b, the inner rail portion 12c, and the indoor side portion 12d are formed on the lower frame 10 in order from the outdoor side. The outer rail portion 12b and the inner rail portion 12c have upper surfaces formed as an outer rail and an inner rail, respectively, and a door wheel 45 provided under the lower arm 40 is placed on the outer rail portion 12b and the inner rail portion 12c.

次に、拡張フラット枠体を選択した場合のサッシについて説明する。図５には拡張フラット枠体を用いたサッシの縦断面図を、図６には拡張フラット枠体を用いたサッシの横断面図を、それぞれ示している。これら各図に示すように枠体１は、上述の基本フラット枠体に対して網戸レールカバー８０と外側アタッチメント７０及び内側アタッチメント７５を設けてなるものである。すなわち、下枠１０の中空部１１や網戸レール部１２ａ、外レール部１２ｂ、内レール部１２ｃ、及び室内側部１２ｄの形状は図２に示したものと同一であり、上枠２０や縦枠３０の形状についても同様である。また、下枠１０の中空部１１内部に設けられる外レール補強材９０及び内レール補強材９１の構成についても図２に示したものと同一である。 Next, the sash when the extended flat frame is selected will be described. FIG. 5 shows a vertical cross-sectional view of a sash using an extended flat frame, and FIG. 6 shows a cross-sectional view of a sash using an extended flat frame. As shown in each of these drawings, the frame 1 is provided with a screen door rail cover 80, an outer attachment 70, and an inner attachment 75 with respect to the basic flat frame described above. That is, the shape of the hollow part 11 of the lower frame 10, the screen door rail part 12a, the outer rail part 12b, the inner rail part 12c, and the indoor side part 12d is the same as that shown in FIG. The same applies to 30 shapes. The configurations of the outer rail reinforcing member 90 and the inner rail reinforcing member 91 provided in the hollow portion 11 of the lower frame 10 are also the same as those shown in FIG.

図７には、図５の下枠１０及び下框４０付近の拡大図を示している。網戸レールカバー８０は、図２に示したものと同様に金属からなり、下枠１０の外側凹部１３の室外面と底面を略覆う被覆部８２と、外側凹部１３の室外面上端部と係合する係合部８３を有している。ただし、被覆部８２の外側凹部１３の室外面を覆う部分については、中空部を有するように形成されており、その上面に平坦部８４が形成されている点で図２に示したものとは異なる。また、平坦部８４に隣接するように網戸レール８１が形成されている。 FIG. 7 shows an enlarged view of the vicinity of the lower frame 10 and the lower eyelid 40 of FIG. The screen door rail cover 80 is made of metal, similar to that shown in FIG. 2, and engages with a covering portion 82 that substantially covers the outer surface and bottom surface of the outer recess 13 of the lower frame 10, and the upper end portion of the outer surface of the outer recess 13. It has the engaging part 83 to do. However, the portion covering the outdoor surface of the outer recessed portion 13 of the covering portion 82 is formed so as to have a hollow portion, and what is shown in FIG. 2 in that a flat portion 84 is formed on the upper surface thereof. Different. A screen door rail 81 is formed so as to be adjacent to the flat portion 84.

次に、各アタッチメントについて説明する。外側アタッチメント７０は、下枠１０の中間凹部１４に長手方向に沿って設けられるもので、外障子４と内障子５の召合せ部分及び下枠１０の両端部近傍以外の領域に設けられる。なお、中間凹部１４の外障子４と内障子５の召合せ部分には、気密性及び水密性確保のための気密ブロック７８が設けられ、下枠１０の両端部近傍は、排水のために空間として流路を形成する。 Next, each attachment will be described. The outer attachment 70 is provided along the longitudinal direction in the intermediate recess 14 of the lower frame 10, and is provided in a region other than the summing part of the outer shoji 4 and the inner shoji 5 and the vicinity of both ends of the lower frame 10. In addition, an airtight block 78 for ensuring airtightness and watertightness is provided at the summing portion of the outer shoji 4 and inner shoji 5 in the intermediate recess 14, and the vicinity of both ends of the lower frame 10 is a space for drainage. To form a flow path.

外側アタッチメント７０は二部材からなり、下枠１０に対して固定される上方に開放した溝形状の基部材７１と、基部材７１の上方を覆うように設けられるカバー部材７２とから構成される。基部材７１は、下枠１０の中間凹部１４底面に形成されている取付部１４ａに対して底面を当接させ、ネジ止めすることによって面固定される。 The outer attachment 70 is composed of two members, and is composed of a groove-shaped base member 71 that is fixed to the lower frame 10 and opens upward, and a cover member 72 that is provided so as to cover the upper portion of the base member 71. The base member 71 is fixed to the surface by bringing the bottom surface into contact with the mounting portion 14a formed on the bottom surface of the intermediate recess 14 of the lower frame 10 and screwing it.

基部材７１は、上部に被係合部７１ａを有しており、カバー部材７２は基部材７１上部の被係合部７１ａに対して係合する係合部７２ａを下部に有している。また、カバー部材７２は上面７３が平面状に形成されており、この上面７３の高さは外レール部１２ｂの上面の高さと略同じであって、また外レール部１２ｂの上面と略連続状とされている。すなわち、カバー部材７２の上面７３は、外レール部１２ｂの上面を室内側に拡張して平坦面を広くしている。 The base member 71 has an engaged portion 71 a at the upper portion, and the cover member 72 has an engaging portion 72 a that engages with the engaged portion 71 a at the upper portion of the base member 71 at the lower portion. The cover member 72 has an upper surface 73 formed in a planar shape, and the height of the upper surface 73 is substantially the same as the height of the upper surface of the outer rail portion 12b, and is substantially continuous with the upper surface of the outer rail portion 12b. It is said that. That is, the upper surface 73 of the cover member 72 extends the upper surface of the outer rail portion 12b to the indoor side to widen the flat surface.

内側アタッチメント７５は、下枠１０の内側凹部１５に長手方向に沿って設けられるもので、下枠１０の両端部近傍以外の領域に設けられる。なお、内側凹部１５の下枠１０両端部近傍には、内障子５が縦枠３０に衝突しないように戸当たりブロック１６が設けられる。 The inner attachment 75 is provided in the inner recess 15 of the lower frame 10 along the longitudinal direction, and is provided in a region other than the vicinity of both end portions of the lower frame 10. A door stop block 16 is provided in the vicinity of both ends of the lower frame 10 of the inner recess 15 so that the inner card 5 does not collide with the vertical frame 30.

内側アタッチメント７５は断面略コ字状に形成され、その両側面には下枠１０の内側凹部１５両側面に形成された取付部１５ａに適合する嵌合部７６が形成されている。下枠１０の内側凹部１５に形成された取付部１５ａは、上述のように嵌合凹部として形成されているので、内側アタッチメント７５の嵌合部７６は、それに対して嵌合自在な嵌合凸部として形成されている。このため、内側アタッチメント７５は内側凹部１５に対して上方から挿入することで容易に取付けることができる。このように、内側アタッチメント７５は内側凹部１５の取付部１５ａに対して面固定される。 The inner attachment 75 is formed in a substantially U-shaped cross section, and fitting portions 76 are formed on both side surfaces of the inner attachment 75 to fit the mounting portions 15a formed on both side surfaces of the inner recess 15 of the lower frame 10. Since the attachment portion 15a formed in the inner concave portion 15 of the lower frame 10 is formed as a fitting concave portion as described above, the fitting portion 76 of the inner attachment 75 is a fitting convex that can be freely fitted thereto. It is formed as a part. For this reason, the inner attachment 75 can be easily attached to the inner recess 15 by being inserted from above. In this manner, the inner attachment 75 is fixed to the mounting portion 15 a of the inner recess 15.

また、内側アタッチメント７５の上面７７は平面状に形成されており、その高さが内レール部１２ｃの上面及び室内側部１２ｄの上面の高さと略同じとされている。また、内側アタッチメント７５の上面７７は、内レール部１２ｃから室内側部１２ｄに渡って設けられており、内レール部１２ｃの上面から室内側部１２ｄの上面までを略連続状として拡張し、平坦面を広くしている。 Further, the upper surface 77 of the inner attachment 75 is formed in a planar shape, and the height thereof is substantially the same as the height of the upper surface of the inner rail portion 12c and the upper surface of the indoor side portion 12d. Further, the upper surface 77 of the inner attachment 75 is provided from the inner rail portion 12c to the indoor side portion 12d, and extends from the upper surface of the inner rail portion 12c to the upper surface of the indoor side portion 12d as a substantially continuous shape. The surface is widened.

外障子４と内障子５については、上述のようにそれぞれ下框４０が室外垂下部４１と室内下端部４３を有しており、外障子４の室外垂下部４１は下枠１０の外側凹部１３に納められ、外障子４の室内下端部４３は外側アタッチメント７０の上面７３に対向配置され、内障子５の室外垂下部４１は下枠１０の中間凹部１４に納められ、内障子５の室内下端部４３は内側アタッチメント７５の上面７７に対向配置される。室外垂下部４１の内側面には気密材７が設けられており、各気密材７が外レール部１２ｂや内レール部１２ｃに対し当接する。また、室内下端部４３の下面にも気密材７が設けられており、各気密材７が外側アタッチメント７０の上面７３や内側アタッチメント７５の上面７７に対し当接する。 As for the external shoji 4 and the internal shoji 5, as described above, the lower arm 40 has the outdoor hanging portion 41 and the indoor lower end portion 43, and the outdoor hanging portion 41 of the external shovel 4 is the outer recess 13 of the lower frame 10. The indoor lower end 43 of the outer shoji 4 is disposed opposite to the upper surface 73 of the outer attachment 70, and the outdoor hanging portion 41 of the inner shoji 5 is received in the intermediate recess 14 of the lower frame 10. The part 43 is disposed to face the upper surface 77 of the inner attachment 75. An airtight material 7 is provided on the inner side surface of the outdoor hanging portion 41, and each airtight material 7 abuts against the outer rail portion 12b and the inner rail portion 12c. Moreover, the airtight material 7 is provided also on the lower surface of the indoor lower end portion 43, and each airtight material 7 comes into contact with the upper surface 73 of the outer attachment 70 and the upper surface 77 of the inner attachment 75.

上框５０や縦框６０の形状については、基本フラット枠体を選択した場合の框体２に用いられるものと同一である。なお、縦框６０のうち内障子５の召合せ框には、室内側に断面中空状の召合せ框補強材を設けている。拡張フラット枠体を選択した場合の框体２は、室外垂下部４１と室内下端部４３を有する下框４０と、室外垂下部４１と室内垂下部４２を有するそれ以外の框とで、断面形状が異なることになる。図８（Ａ）には、下框４０と縦框６０の溶着部分の拡大図を示す。下框４０と縦框６０は、それぞれ端部を斜め４５°に切断し、端面を互いに突き合わせて溶着し固定するようにしている。 The shapes of the upper rod 50 and the vertical rod 60 are the same as those used for the frame 2 when the basic flat frame is selected. In addition, the sump heel of the inner shoji 5 in the vertical cage 60 is provided with a summit reinforced material having a hollow cross section on the indoor side. When the extended flat frame is selected, the housing 2 includes a lower housing 40 having an outdoor hanging portion 41 and an indoor lower end portion 43, and other housings having an outdoor hanging portion 41 and an indoor hanging portion 42. Will be different. FIG. 8A shows an enlarged view of the welded portion of the lower rod 40 and the vertical rod 60. The lower rod 40 and the vertical rod 60 each have an end portion cut at an angle of 45 °, and the end surfaces are brought into contact with each other to be welded and fixed.

この場合に縦框６０の室内垂下部に相当する部分の先端は、下框４０の室内下端部４３の先端と突き合わされる。縦框６０の室外垂下部に相当する部分の先端は、室内垂下部に相当する部分の先端と同じ見付方向位置にあるので、室内下端部４３よりも見付方向外側まで延出している下框４０の室外垂下部４１は、縦框６０との突き合わせ面よりも外側に配置されることになる。上述のように縦框６０の室外垂下部に相当する部分と、下框４０の室外垂下部４１にはそれぞれ気密材７が設けられており、そのままでは気密材７が連続状とならない。図８においては、ハッチングで示した部分が気密材７を表している。 In this case, the tip of the portion corresponding to the indoor hanging portion of the vertical rod 60 is abutted with the tip of the indoor lower end 43 of the lower rod 40. Since the tip of the part corresponding to the outdoor hanging part of the vertical shaft 60 is at the same position as the tip of the part corresponding to the indoor hanging part, it extends below the indoor lower end part 43 to the outside in the finding direction. The outdoor hanging portion 41 of the heel 40 is disposed outside the butt face with the vertical heel 60. As described above, the airtight material 7 is provided in the portion corresponding to the outdoor hanging portion of the vertical rod 60 and the outdoor hanging portion 41 of the lower rod 40, and the airtight material 7 is not continuous as it is. In FIG. 8, the hatched portion represents the airtight material 7.

そこで、下框４０は溶着部分近傍で室外垂下部４１の気密材７を切欠き、縦框６０も溶着部分近傍で室外垂下部に相当する部分の気密材７を切欠いて、溶着部分には室内面に気密部４６ａを有したＬ字状のコーナーブロック４６を設ける。コーナーブロック４６を取付けた溶着部分の拡大図を図８（Ｂ）に示す。気密部４６ａは、下框４０の気密材７及び縦框６０の気密材７とそれぞれ連続状となるように形成しており、これによって下框４０と縦框６０の気密を連続的になすようにしている。 Therefore, the lower rod 40 cuts out the airtight material 7 of the outdoor hanging portion 41 near the welded portion, and the vertical rod 60 also cuts out the portion of the airtight material 7 corresponding to the outdoor hanging portion near the welded portion. An L-shaped corner block 46 having an airtight portion 46a on the surface is provided. FIG. 8B shows an enlarged view of the welded portion to which the corner block 46 is attached. The airtight portion 46a is formed so as to be continuous with the airtight material 7 of the lower rod 40 and the airtight material 7 of the vertical rod 60, so that the airtightness of the lower rod 40 and the vertical rod 60 is made continuous. I have to.

次に、外障子４及び内障子５と枠体１の位置関係について説明する。図７に示すように、カバー部材７２は、室内側端部を断面略Ｌ字状に形成した室内面部７４を有している。内障子５の下框４０に形成された室外垂下部４１は、下枠１０の中間凹部１４に納められ、その室外面はカバー部材７２の室内面部７４と所定間隔の隙間を有して対向している。ここで、室外垂下部４１の室外面とカバー部材７２の室内面部７４の間隔は、室内外の気圧差などによる内障子５の室外側への移動量を規定する。したがって、この間隔はできるだけ小さくすることで内障子５の移動量を小さくすることができる。しかし一方で、気温の変化による樹脂材の変形を考慮すると、室外垂下部４１の室外面とカバー部材７２の室内面部７４の間には、ある程度の隙間を設けておくことが必要である。 Next, the positional relationship between the outer shoji 4 and inner shoji 5 and the frame 1 will be described. As shown in FIG. 7, the cover member 72 has an indoor surface portion 74 in which an indoor side end portion is formed in a substantially L-shaped cross section. The outdoor hanging part 41 formed on the lower collar 40 of the inner shoji 5 is housed in the intermediate recess 14 of the lower frame 10, and the outdoor surface thereof is opposed to the indoor surface part 74 of the cover member 72 with a predetermined gap. ing. Here, the distance between the outdoor surface of the outdoor hanging portion 41 and the indoor surface portion 74 of the cover member 72 defines the amount of movement of the inner shoji 5 to the outdoor side due to an atmospheric pressure difference between the indoor and the outdoor. Therefore, the amount of movement of the inner shoji 5 can be reduced by making this interval as small as possible. On the other hand, however, considering the deformation of the resin material due to changes in temperature, it is necessary to provide a certain gap between the outdoor surface of the outdoor hanging portion 41 and the indoor surface portion 74 of the cover member 72.

図９は、図７において障子が室外側に移動した状態を示した図である。この図に示すように内障子５は、下框４０の室外垂下部４１の室外面がカバー部材７２の室内面部７４に当接する位置まで室外側に移動する。この際、下框４０の戸車４５は内レール部１２ｃの内レール１２ｆに乗り上げる。ただし、戸車４５は内レール１２ｆから完全に外れることがないように室外垂下部４１の室外面とカバー部材７２の室内面部７４の隙間を設定している。 FIG. 9 is a view showing a state in which the shoji is moved to the outdoor side in FIG. As shown in this figure, the inner shoji 5 moves to the outdoor side to a position where the outdoor surface of the outdoor hanging portion 41 of the lower collar 40 contacts the indoor surface portion 74 of the cover member 72. At this time, the door wheel 45 of the lower arm 40 rides on the inner rail 12f of the inner rail portion 12c. However, the gap between the outdoor surface of the outdoor hanging portion 41 and the indoor surface portion 74 of the cover member 72 is set so that the door wheel 45 is not completely detached from the inner rail 12f.

本実施形態では、内レール部１２ｃの内レール１２ｆは断面円弧状の凸部として形成されており、室外垂下部４１の室外面とカバー部材７２の室内面部７４の隙間が内レール１２ｆの幅の約２分の１とされている。したがって、図９に示すように、内障子５が室外側に移動し、室外垂下部４１の室外面がカバー部材７２の室内面部７４に当接する位置で、戸車４５の室外面が内レール１２ｆの頂部に配置される状態となり、戸車４５は内レール１２ｆからは外れていない。 In the present embodiment, the inner rail 12f of the inner rail portion 12c is formed as a convex portion having an arc cross section, and the gap between the outdoor surface of the outdoor hanging portion 41 and the indoor surface portion 74 of the cover member 72 is the width of the inner rail 12f. It is about half. Therefore, as shown in FIG. 9, the inner surface of the door wheel 45 is moved to the outdoor side of the inner rail 12 f at a position where the inner shovel 5 moves to the outdoor side and the outdoor surface of the outdoor hanging portion 41 contacts the indoor surface portion 74 of the cover member 72. It will be in the state arrange | positioned at the top part, and the doorwheel 45 is not removed from the inner rail 12f.

室外垂下部４１の室外面とカバー部材７２の室内面部７４との隙間をこのように設定することにより、樹脂材の変形を考慮しつつも、室内外の気圧差などによって内障子５が室外側に移動した場合、戸車４５が中間凹部１４に落ち込むことがなく、扱いやすいサッシとすることができる。 By setting the gap between the outdoor surface of the outdoor hanging portion 41 and the indoor surface portion 74 of the cover member 72 in this way, the inner shoji 5 can be moved to the outdoor side due to a difference in the atmospheric pressure outside the room while taking into account the deformation of the resin material. When the door is moved to the position, the door 45 does not fall into the intermediate recess 14, and the sash can be easily handled.

また、外障子４についても、同様の位置関係に配置される。図７に示すように、外障子４の場合には、室外垂下部４１の室外面は網戸レールカバー８０の室内面部８５と所定間隔の隙間を有して対向する。そこで、この隙間を戸車４５がレールから完全に外れることがないように、内障子５の場合と同様の間隔に設定する。すなわち、室外垂下部４１の室外面と網戸レールカバー８０の室内面部８５の隙間が、外レール１２ｅの幅の約２分の１とされている。こうすることで、図９に示すように、内障子５が室外側に移動した場合に、外障子４の下框４０における室外垂下部４１の室外面が網戸レールカバー８０の室内面部８５に当接し、この状態で下框４０の戸車４５は、外レール部１２ｂの外レール１２ｅの頂部まで乗り上げた状態となり、戸車４５は外レール１２ｅからは外れていない。 The external shoji 4 is also arranged in the same positional relationship. As shown in FIG. 7, in the case of the shoji 4, the outdoor surface of the outdoor hanging portion 41 faces the indoor surface portion 85 of the screen door rail cover 80 with a predetermined gap. Therefore, this gap is set to the same interval as in the case of the inner shoji 5 so that the door wheel 45 is not completely detached from the rail. That is, the gap between the outdoor surface of the outdoor hanging portion 41 and the indoor surface portion 85 of the screen door rail cover 80 is set to about one half of the width of the outer rail 12e. In this way, as shown in FIG. 9, when the inner shovel 5 moves to the outdoor side, the outdoor surface of the outdoor hanging portion 41 on the lower arm 40 of the outer shoji 4 contacts the indoor surface portion 85 of the screen door rail cover 80. In this state, the door wheel 45 of the lower arm 40 is in a state of riding on the top of the outer rail 12e of the outer rail portion 12b, and the door wheel 45 is not detached from the outer rail 12e.

次に、縦枠３０の形状について説明する。図１０には、図６における縦枠３０及び縦框６０付近の拡大図を示している。この図に示すように、縦枠３０の外レール部１２ｂの室外面は、縦框６０の気密材７が当接する部分から先端側にかけて、室内側に向かう傾斜面とされて傾斜部３１を形成している。また、縦枠３０の内レール部１２ｃについても同様に形成されている。なお、枠体１は下枠１０と上枠２０及び縦枠３０が全て略同じ断面形状を有しているから、外レール部１２ｂと内レール部１２ｃは四周に渡って同様に傾斜部３１を有している。 Next, the shape of the vertical frame 30 will be described. FIG. 10 shows an enlarged view of the vicinity of the vertical frame 30 and the vertical rod 60 in FIG. As shown in this figure, the outdoor surface of the outer rail portion 12b of the vertical frame 30 is an inclined surface toward the indoor side from the portion where the airtight material 7 of the vertical rod 60 abuts to the front end side to form the inclined portion 31. is doing. Further, the inner rail portion 12c of the vertical frame 30 is formed in the same manner. In the frame 1, the lower frame 10, the upper frame 20, and the vertical frame 30 all have substantially the same cross-sectional shape, so that the outer rail portion 12 b and the inner rail portion 12 c are similarly provided with the inclined portion 31 over the four circumferences. Have.

このように外レール部１２ｂ及び内レール部１２ｃに傾斜部３１を設けたことにより、外障子４や内障子５を開き始める際に、気密材７と各レール部との間に生じる摩擦による抵抗力を小さくすることができ、障子の初動開閉力を小さくすることができるので、小さな力で障子を開閉することができる。 By providing the inclined portion 31 on the outer rail portion 12b and the inner rail portion 12c as described above, resistance due to friction generated between the airtight member 7 and each rail portion when the outer shoji 4 and the inner shoji 5 are opened. Since the force can be reduced and the initial opening and closing force of the shoji can be reduced, the shoji can be opened and closed with a small force.
