Description

本発明は、住宅用サッシのシール材に関する。より詳細には、住宅用サッシのサッシ枠内にスライドして開閉自在に嵌合された障子とサッシ枠との隙間を塞ぐ住宅用サッシのシール材に関するものである。   The present invention relates to a sealing material for a housing sash. More specifically, the present invention relates to a sealing material for a housing sash that closes a gap between a shoji frame that is slidably fitted in a sash frame of a housing sash and that can be freely opened and closed.

図９に示すように、通常の住宅用サッシは、上枠１１，下枠１２，縦枠１３，１４からなる矩形状のサッシ枠１０内に、２枚の障子２１，２２が引き違いに嵌合されている。これにより、２枚の障子２１，２２はスライドして開閉自在で、閉鎖時には両障子２１，２２の召合せ框２１Ａ，２２Ａ間に設けられたロック部材１００を施錠することによって両障子２１，２２は互いに引き寄せられる。   As shown in FIG. 9, in a normal residential sash, two shojis 21 and 22 are fitted in a rectangular sash frame 10 composed of an upper frame 11, a lower frame 12, and vertical frames 13 and 14. Are combined. As a result, the two shojis 21 and 22 are slidable to open and close, and when they are closed, both shojis 21 and 22 are locked by locking the lock member 100 provided between the summing rods 21A and 22A of both shojis 21 and 22. Are attracted to each other.

このような障子２１，２２とサッシ枠１０との間には、施錠時及び無施錠時に両障子２１，２２を閉鎖したときに両者間の隙間を塞いで室外側から室内側に進入する音を効果的に低減するための各種シール材が設けられている。
障子２１，２２の上框２１Ｂ，２２Ｂには、例えば、図１０に示すような、シール材３１，３２が室外側と室内側にそれぞれ設けられ、障子２１，２２の戸先框２１Ｃ，２２Ｃには、図１１に示すような、シール材３３が室外側に設けられている。なお、図１０は図９のＡ−Ａ線拡大断面を示し、図１１は図９のＢ−Ｂ線拡大断面を示している。
シール材３１，３２は、上框２１Ｂ，２２Ｂに沿って左右（図９において左右）に連続して延び、シール材３３は、戸先框２１Ｃ，２２Ｃに沿って上下（図９において上下）に連続して延びているが、上框２１Ｂと戸先框２１Ｃのコーナー部及び上框２２Ｂと戸先框２２Ｃのコーナー部においてシール材３１，３２とシール材３３は繋がっていない。
室外側のシール部３１は、上框２１Ｂ，２２Ｂに形成された凹溝２１ＢＭ内の室外側上部に設けられた嵌合部２１ＢＫに嵌め込まれる取付部３１ａと、その取付部３１ａに一体成形されたリップ状のシール部３１ｂからなり、シール部３１ｂの先端部がサッシ枠１０の上枠１１に突設されたフランジＦ１の室外側側面に接触している。また、室内側のシール部３２は、全体がリップ状であり、上框２１Ｂ，２２Ｂに形成された凹溝２１ＢＭ内の室内側上部にその付け根部が接着され、先端部がサッシ枠１０の上枠１１に突設されたフランジＦ１の室内側側面に接触している。 Between such shojis 21 and 22 and the sash frame 10, when both shojis 21 and 22 are closed when locked and unlocked, a sound is entered between the outside and the inside from the outside of the room. Various sealing materials are provided for effective reduction.
For example, as shown in FIG. 10, seal materials 31 and 32 are provided on the outdoor side and the indoor side respectively on the upper side 21 </ b> B and 22 </ b> B of the shoji 21 and 22. As shown in FIG. 11, a sealing material 33 is provided on the outdoor side. 10 shows an enlarged cross section taken along line AA in FIG. 9, and FIG. 11 shows an enlarged cross section taken along line BB in FIG.
The sealing materials 31 and 32 continuously extend from side to side (left and right in FIG. 9) along the upper flanges 21B and 22B, and the sealing material 33 extends vertically (up and down in FIG. 9) along the door-end rods 21C and 22C. Although extending continuously, the sealing materials 31 and 32 and the sealing material 33 are not connected to each other at the corners of the upper rod 21B and the door rod 21C and at the corners of the upper rod 22B and the door rod 22C.
The outdoor-side seal portion 31 is integrally formed with a mounting portion 31a that is fitted into a fitting portion 21BK provided in the upper portion of the outdoor side in the concave groove 21BM formed in the upper flanges 21B and 22B, and the mounting portion 31a. It consists of a lip-shaped seal portion 31b, and the tip of the seal portion 31b is in contact with the outdoor side surface of the flange F1 projecting from the upper frame 11 of the sash frame 10. Further, the indoor side seal portion 32 has a lip shape as a whole, and a base portion thereof is bonded to an upper portion on the indoor side in the concave groove 21BM formed in the upper flanges 21B and 22B, and a tip portion thereof is above the sash frame 10. It contacts the indoor side surface of the flange F <b> 1 projecting from the frame 11.

一方、シール材３３は、戸先框２１Ｃ，２２Ｃに形成された凹溝２１ＣＭ内の室外側端部に設けられた嵌合部２１ＣＫに嵌め込まれる取付部３３ａと、その取付部３３ａに一体成形された３本のリップ状のシール部３３ｂからなり、障子２１の閉鎖時に、シール部３３ｂの先端部がサッシ枠１０の縦枠１３に突設されたフランジＦ２の室外側側面に接触している。
また、図１２に示すように、戸先框２１Ｃ，２２Ｃの上下２ケ所には、障子２１，２２の閉鎖時に、サッシ枠１０の縦枠１３，１４に突設されたフランジＦ２の先端に当接する位置決め部材３４が設けられている。なお、図１２は図９のＣ−Ｃ線拡大断面を示している。 On the other hand, the sealing material 33 is integrally formed with a mounting portion 33a that is fitted into a fitting portion 21CK provided at an outdoor side end portion in the recessed groove 21CM formed in the door rods 21C and 22C, and the mounting portion 33a. Further, when the shoji 21 is closed, the front end portion of the seal portion 33b is in contact with the outdoor side surface of the flange F2 protruding from the vertical frame 13 of the sash frame 10.
In addition, as shown in FIG. 12, at the upper and lower portions of the door toe fences 21C and 22C, when the shoji screens 21 and 22 are closed, they are in contact with the tips of the flanges F2 protruding from the vertical frames 13 and 14 of the sash frame 10. A positioning member 34 in contact therewith is provided. FIG. 12 shows an enlarged cross section taken along the line CC of FIG.

障子とサッシ枠間の隙間をシール材で塞いで遮音性を高めたサッシ構造は種々知られている（例えば、特許文献１，２等）。   Various sash structures in which a gap between the shoji and the sash frame is closed with a sealing material to improve sound insulation are known (for example, Patent Documents 1 and 2).

しかしながら、従来例として示した住宅用サッシには形状の異なる３種類のシール材３１，３２，３３が使用されているので部品点数が多く、組み付けに工数がかかるとともにコスト高になるといった問題がある。
また、フランジＦ１，Ｆ２に弾接するシール材３１，３２，３３のリップ部は肉厚が薄いので反力が弱くなりがちで障子２１，２２の安定性が懸念されるとともに、フランジＦ１，Ｆ２に対する弾接量が少ないと障子２１，２２のバラツキなどに対応することができず遮音効果が低下するといった恐れもある。
さらには、障子２１，２２の上框２１Ｂと戸先框２１Ｃのコーナー部及び上框２２Ｂと戸先框２２Ｃのコーナー部においては、シール材３１，３２とシール材３３は繋がっていないので、特にコーナー部では室外側から室内側に音が進入してしまう。 However, since the three types of sealing materials 31, 32, and 33 having different shapes are used in the residential sash shown as the conventional example, there is a problem that the number of parts is large, the number of man-hours is increased, and the cost is increased. .
Further, since the lip portions of the sealing materials 31, 32, 33 that are in elastic contact with the flanges F1, F2 are thin, the reaction force tends to be weak, and there is a concern about the stability of the shojis 21, 22, and the lip portions with respect to the flanges F1, F2 are concerned. If the amount of elastic contact is small, it may not be possible to cope with variations in the shojis 21 and 22, and the sound insulation effect may be reduced.
Furthermore, since the sealing materials 31 and 32 and the sealing material 33 are not connected in the corner portions of the upper and lower doors 21B and 21C of the shoji 21 and 22 and the corners of the upper and lower doors 22B and 22C, At the corner, sound enters from the outdoor side to the indoor side.

また、特許文献１に記載のシール材は、障子２１，２２の下框２１Ｄ，２２Ｄに相当する部位に取付けられ、防音機能と防水機能に優れるものであるので、障子２１，２２の上框２１Ｂ，２２Ｂ及び戸先框２１Ｃ，２２Ｃからは音が進入してしまう。
さらに、特許文献２に記載のシール材は、障子２１，２２の上框２１Ｂ，２２Ｂ及び戸先框２１Ｃ，２２Ｃに相当する部位に合成ゴムからなるスポンジ材を挟むものであるので、遮音性をより高めようとすると障子２１，２２の開閉性が悪くなったり、スポンジ材が破れるなど損傷してかえって遮音性を低下させるといった恐れがある。 Moreover, since the sealing material of patent document 1 is attached to the site | part equivalent to the lower collars 21D and 22D of the shoji 21 and 22 and is excellent in a soundproof function and a waterproof function, the upper arm 21B of the shoji 21 and 22 is used. , 22B and the door-towers 21C, 22C enter the sound.
Furthermore, since the sealing material described in Patent Document 2 has a sponge material made of synthetic rubber sandwiched between portions corresponding to the upper ridges 21B and 22B and the door end ridges 21C and 22C of the shoji 21 and 22, the sound insulation is further improved. If it tries to do so, the opening / closing performance of the shojis 21 and 22 may be deteriorated, or the sponge material may be broken and damaged, and the sound insulation may be lowered.

そこで、本発明の目的とするところは、部品点数が少なくて組み付けが容易でしかも遮音性に優れる住宅用サッシのシール材を提供することにある。   Therefore, an object of the present invention is to provide a sealing material for a housing sash that has a small number of parts, is easy to assemble, and is excellent in sound insulation.

なお、括弧内の記号は、図面および後述する発明を実施するための形態に記載された対応要素または対応事項を示す。   Note that symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and modes for carrying out the invention described later.

本発明によれば、シール材は、障子の上框又は戸先框のいずれか、あるいは上框及び戸先框の両方に沿って取付けられる両側壁部と底壁部からなる断面略コ字状の取付基部と、その取付基部の両端部から底壁部に向かって内方に延び、前記断面略コ字状の開口部に案内された前記サッシ枠に突設されたフランジを挟みそのフランジの側面に弾接する室外側リップ部及び室内側リップ部とからなる一部品であるので、従来のものと比較して部品点数が抑えられる。
これにより、障子に対するシール材の組み付けが容易になるとともにコストの削減を図れる。
特に、戸先框にシール材を取付けた場合に、障子の閉鎖時にフランジの先端を取付基部の底壁部に底突きさせ、底壁部をストッパーとして機能させるようにすれば、位置決め部材も不要になるので、一層、シール材の組み付けが容易になるとともにコストの削減となる。 According to the present invention, the sealing material has a substantially U-shaped cross-section composed of both side wall portions and bottom wall portions that are attached along either the upper or door side of the shoji or both the upper and door side walls. And a flange projecting inwardly from the both ends of the mounting base toward the bottom wall portion and guided by the opening having a substantially U-shaped cross section, and sandwiching the flange projecting from the flange. Since this is a single part consisting of the outdoor lip part and the indoor lip part that are elastically contacted with the side surfaces, the number of parts can be reduced compared to the conventional one.
As a result, the assembly of the sealing material to the shoji can be facilitated and the cost can be reduced.
In particular, when a sealing material is attached to the door toe, the positioning member is not required if the front end of the flange is made to butt against the bottom wall of the mounting base when the shoji is closed and the bottom wall functions as a stopper. As a result, the assembly of the sealing material becomes easier and the cost is reduced.

また、シール材の取付基部は断面略コ字状であるので、障子の上框や戸先框に断面略矩形状の凹溝を設けてその凹溝にシール材の取付基部を嵌め込む構成にすれば、シール材を障子に安定して取付けることができる。
さらに、シール材は、取付基部の両端部から底壁部に向かって延設された室外側リップ及び室内側リップでフランジを挟んで弾接するものであるので、障子自体も安定化するとともに、十分な弾接量を確保できるので障子の形状バラツキや障子とフランジ間の位置バラツキなどにも対応することができ、安定した遮音効果が得られ、その上、断熱性にも優れる。 In addition, since the mounting base portion of the sealing material has a substantially U-shaped cross section, a concave groove having a substantially rectangular cross section is provided in the upper and door of the shoji, and the mounting base portion of the sealing material is fitted into the concave groove. Then, the sealing material can be stably attached to the shoji.
Furthermore, the seal material is elastically contacted by sandwiching the flange between the outdoor lip and the indoor lip extending from both ends of the mounting base toward the bottom wall, so that the shoji itself is stabilized and sufficiently Therefore, it is possible to cope with the variation in the shape of the shoji and the position variation between the shoji and the flange, so that a stable sound insulation effect can be obtained and the heat insulation is also excellent.

さらに、本発明によれば、戸先框に取付けられたシール材の取付基部は、障子の閉時にサッシ枠に突設されたフランジの先端に当接する部位を有し、その当接する部位、例えば、フランジの先端と直接に当接する部位に、あるいは、取付基部の側壁部や底壁部から、フランジの先端に当接する部位を突設し、その突設した部位と取付基部の底壁部との間に、あるいは、取付基部の底壁部を部分的に内方に突出させて、フランジの先端に当接する部位（凸部）とするともに、前記内方側とは逆側となる外方側に形成される凹部に、緩衝用のスポンジ材を設けたので、障子を閉めるときの位置決めをするストッパーとしての機能を果たし、フランジの先端が底突きするとき発生する音を効果的に抑制する。 Furthermore, according to the present invention, the mounting base portion of the sealing member attached to the door leading end stiles has a site at the tip of the flange protruding from the sash frame to the closed shoji abutting, portion thereof abuts, e.g. A portion that abuts against the front end of the flange protrudes from a portion that abuts directly on the front end of the flange, or from the side wall or bottom wall portion of the mounting base, and the projecting portion and the bottom wall portion of the mounting base Or the bottom wall of the mounting base is partially protruded inward to form a portion that contacts the tip of the flange (projection), and the outer side opposite to the inner side Since the cushioning sponge material is provided in the recess formed on the side, it functions as a stopper for positioning when closing the shoji and effectively suppresses the sound generated when the flange tip bottoms out. .

また、サッシ枠から延びるフランジは、その側面が、室外側リップ部及び室内側リップ部でシールされるとともにその先端もスポンジ材でシールされる構成であり、計３点が面によってシールされるので、遮音性は向上し断熱性にも優れる。このとき、シール材の室外側リップ部及び室内側リップをソリッド材で形成すれば、障子の開閉性を特に悪くすることなく、スポンジ材と相俟ってシール性を高めることができる。無論シール材全体が微発泡を含む発泡体であってもよい。
なおスポンジ材は、戸先框において部分的、例えば、上下２ケ所にするだけで障子を閉めるときのストッパーになるが、シール材の取付基部と同様に戸先框に沿って上下に連続的に設けるようにすれば遮音性はさらに向上し断熱効果も向上する。 In addition, the flange extending from the sash frame is configured such that the side surface is sealed by the outdoor lip portion and the indoor lip portion, and the tip is also sealed by the sponge material, and a total of three points are sealed by the surface. Sound insulation is improved and heat insulation is excellent. At this time, if the outdoor lip portion and the indoor lip of the sealing material are formed of a solid material, the sealing performance can be enhanced in combination with the sponge material without particularly deteriorating the opening / closing performance of the shoji. Of course, the whole sealing material may be a foam containing fine foaming.
Sponge material can be used as a stopper when closing the shoji partially at the door toe, for example, just two places at the top and bottom. If provided, the sound insulation is further improved and the heat insulation effect is improved.

特に、請求項５及び請求項６に係る発明によれば、フランジの先端が直接的にスポンジ材に当接しないため、スポンジ材は破れ難い。   In particular, according to the inventions according to claims 5 and 6, since the tip of the flange does not directly contact the sponge material, the sponge material is hardly broken.

It extends rightward from the frame 14 and is elastically contacted with the indoor side surface of the flange F2 guided by an opening having a substantially U-shaped cross section of the mounting base 51.

また、シール材５０は、図４及び図５で示すように、障子２１の上框２１Ｂと戸先框２１Ｃのコーナー部，及び障子２２の上框２２Ｂと戸先框２２Ｃのコーナー部では連続していて、全体形状では略Ｌ字状である。本発明の実施形態に係る住宅用サッシでは障子２１，２２の数に対応して２つの略Ｌ字状のシール材５０が取付けられる。
すなわち、上框２１Ｂ，２２Ｂに取付けられた取付基部５１の側端部と戸先框２１Ｃ，２２Ｃに取付けられた取付基部５１の上端部は接続されるとともに、上框２１Ｂ，２２Ｂ及び戸先框２１Ｃ，２２Ｃにおいて、取付基部５１に延設された室外側リップ部５２の端部同士及び室内側リップ部５３の端部同士も接続されている。
それらコーナー部における接続は、図６（ａ）に示すような、金型を使用した型成形接続による方法や、図６（ｂ）に示すような、押出成形された２本のシール材の端部同士を接着剤などを使用して接続する方法によって行われる。
なお、サッシ枠１０の上枠１１から延びるフランジＦ１と縦枠１３から延びるフランジＦ２もコーナー部では接続され、略Ｌ字状に連続的に延びることが好ましい。 Further, as shown in FIGS. 4 and 5, the sealing material 50 is continuous at the corners of the upper screen 21 </ b> B and the door toe 21 </ b> C of the shoji 21 and at the corners of the upper foot 22 </ b> B of the shoji 22 and the door toe 22 </ b> C. The overall shape is substantially L-shaped. In the sash for a house according to the embodiment of the present invention, two substantially L-shaped sealing members 50 are attached corresponding to the number of shojis 21 and 22.
That is, the side end of the mounting base 51 attached to the upper rod 21B, 22B and the upper end of the mounting base 51 attached to the door toe 21C, 22C are connected, and the upper rod 21B, 22B and the door toe are connected. In 21C and 22C, the ends of the outdoor lip portion 52 extended to the attachment base 51 and the ends of the indoor lip portion 53 are also connected.
Connections at these corners can be achieved by a method using mold connection as shown in FIG. 6 (a), or by the end of two extruded seal members as shown in FIG. 6 (b). It is performed by a method of connecting the parts using an adhesive or the like.
In addition, it is preferable that the flange F1 extended from the upper frame 11 of the sash frame 10 and the flange F2 extended from the vertical frame 13 are also connected at the corner portion, and extend continuously in a substantially L shape.

また、図３及び図９に示すように、戸先框２１Ｃ，２２Ｃの上下２ケ所には、障子２１，２２の閉鎖時に、サッシ枠１０の縦枠１３，１４に突設されたフランジＦ２の先端に当接する緩衝用のスポンジ材Ｓが独立して部分的に設けられている。
スポンジ材Ｓは、取付基部５１の底壁部５１ｃの内面側（取付基部５１の開口部に案内されるフランジＦ２側）に設けられ、図３（ａ）から図３（ｂ）に示すように、障子２１，２２の閉時に対向するフランジＦ２の先端に直接に当接し撓むことによりフランジＦ２の先端を周囲から覆い隠すようになっている。そして、スポンジＳは、フランジＦ２の先端が底突きすることによって障子２１，２２の位置決めを行うストッパーとしても機能する。スポンジ材Ｓは、ゴム様弾性体で、ＥＰＤＭゴムや熱可塑性エラストマーからなり、比重は０．０５〜１．１である。また、シール材５０と別体で貼り付けされても、シール材５０と同時に一体成形されていてもよい。 As shown in FIGS. 3 and 9, flanges F <b> 2 projecting from the vertical frames 13 and 14 of the sash frame 10 when the shoji 21 and 22 are closed are located at the upper and lower portions of the door toe fences 21 </ b> C and 22 </ b> C. A cushioning sponge material S that is in contact with the tip is partially provided independently.
The sponge material S is provided on the inner surface side (the flange F2 side guided by the opening of the mounting base 51) of the bottom wall 51c of the mounting base 51, as shown in FIGS. 3 (a) to 3 (b). When the shoji 21 and 22 are closed, the front end of the flange F2 is directly abutted and bent so as to cover the front end of the flange F2 from the surroundings. The sponge S also functions as a stopper for positioning the shojis 21 and 22 by the bottom end of the flange F2. The sponge material S is a rubber-like elastic body made of EPDM rubber or thermoplastic elastomer, and has a specific gravity of 0.05 to 1.1. Further, it may be attached separately from the sealing material 50 or may be integrally formed simultaneously with the sealing material 50.

なお、シール材５０を構成する取付基部５１，室外側リップ部５２及び室内側リップ部５３の材質は、特に限定されるわけではないが、ゴム様弾性体であってＥＰＤＭゴムなどのソリッドゴム材や熱可塑性エラストマーなどのソリッド樹脂材からなり、障子２１，２２に組み付けたときの安定性を図るとともに、フランジＦ１，Ｆ２に弾接したときの障子２１，２２の開閉性を良好なものにしている。また、シール材５０の軽量化のためにソリッド材ではなくスポンジ材（微発泡のものも含む）であってもよい。
さらに、室外側リップ部５２及び室内側リップ部５３のフランジＦ１，Ｆ２に弾接する部位に水性シリコーンなどの摺動材を塗布したり、摺動材を貼着したり共押出しして障子２１，２２の開閉性をさらに良好にすることもできる。 The material of the mounting base 51, the outdoor lip portion 52, and the indoor lip portion 53 constituting the seal member 50 is not particularly limited, but is a rubber-like elastic body such as a solid rubber material such as EPDM rubber. It is made of solid resin material such as plastic elastomer and is designed to be stable when assembled to the shoji 21 and 22, and to make the shoji 21 and 22 open and close when elastically contacted with the flanges F1 and F2. Yes. Further, in order to reduce the weight of the sealing material 50, a sponge material (including a fine foamed material) may be used instead of a solid material.
Further, sliding material such as aqueous silicone is applied to the portions of the outdoor lip portion 52 and the indoor lip portion 53 that are in elastic contact with the flanges F1 and F2, or sliding material is attached or coextruded to produce the shoji 21, The opening / closing property of 22 can be further improved.

以上のように構成された本実施形態に係る住宅用サッシのシール材５０は、障子２１，２２の上框２１Ｂ，２２Ｂ及び戸先框２１Ｃ，２２Ｃの両方に沿って取付けられる両側壁部５１ａ，５１ｂと底壁部５１ｃからなる断面略コ字状の取付基部５１と、その取付基部５１の両端部から底壁部５１ｃに向かって延び、断面略コ字状の開口部に案内されたサッシ枠１０に突設されたフランジＦ１，Ｆ２を挟みそのフランジＦ１，Ｆ２の側面に弾接する室外側リップ部５２及び室内側リップ部５３とからなる一部品であるので、障子２１，２２に対するシール材５０の組み付けが容易になるとともにコストの削減を図れる。   The sealing material 50 of the sash for a house according to the present embodiment configured as described above includes both side wall portions 51a attached along both the upper side 21B and 22B of the shoji 21 and 22 and the door end side 21C and 22C. A mounting base 51 having a substantially U-shaped cross section including 51b and a bottom wall 51c, and a sash frame extending from both ends of the mounting base 51 toward the bottom wall 51c and guided to an opening having a substantially U-shaped cross section. 10 is a part composed of an outdoor lip portion 52 and an indoor lip portion 53 which are in contact with the side surfaces of the flanges F1 and F2 with the flanges F1 and F2 projecting from the flange 10 therebetween. Can be easily assembled and the cost can be reduced.

また、シール材５０の取付基部５１の形状は断面略コ字状であり、障子２１，２２の上框２１Ｂ，２２Ｂ及び戸先框２１Ｃ，２２Ｃに設けられた断面略矩形状の凹溝２１ＢＭ，２２ＢＭ，２１ＣＭ，２２ＣＭに対して嵌め込まれるようにして取付けられるので、シール材５０を障子２１，２２に安定して取付けることができる。
さらに、シール材５０は、取付基部５１の両端部から底壁部５１ｃに向かって延設された室外側リップ５２及び室内側リップ５３でフランジＦ１，Ｆ２を挟んで弾接するものであるので、障子２１，２２自体も安定化するとともに、十分な弾接量を確保できるので障子２１，２２の形状バラツキや障子２１，２２とフランジＦ１，Ｆ２間の位置バラツキなどにも対応することができ、安定した遮音効果が得られ、その上、断熱性にも優れる。 In addition, the shape of the mounting base 51 of the sealing material 50 is substantially U-shaped in cross section, and the concave groove 21BM having a substantially rectangular cross section provided in the upper collars 21B and 22B and the door end fences 21C and 22C of the shojis 21 and 22. Since it is attached so as to be fitted to 22BM, 21CM, and 22CM, the sealing material 50 can be stably attached to the shojis 21 and 22.
Further, since the sealing material 50 is elastically contacted with the flanges F1 and F2 sandwiched between the outdoor lip 52 and the indoor lip 53 extending from both ends of the mounting base 51 toward the bottom wall 51c. 21 and 22 itself can be stabilized, and a sufficient amount of elastic contact can be secured, so that it is possible to cope with variations in the shape of the shojis 21 and 22 and position variations between the shojis 21 and 22 and the flanges F1 and F2. Sound insulation effect is obtained, and in addition, heat insulation is excellent.

また、シール材５０は、その全体形状を略Ｌ字状にして上框２１Ｂ，２２Ｂ及び戸先框２１Ｃ，２２Ｃに一体的に取付けられるので、組み付けはさらに容易になるとともに、上框２１Ｂ，２２Ｂと戸先框２１Ｃ，２２Ｃのコーナー部でもシール材５０は連続しているので室外側から室内側に音が進入することをコーナー部においても確実に抑制することができ、断熱性にも優れる。   Further, since the seal member 50 is formed in a substantially L shape and is integrally attached to the upper collars 21B and 22B and the door-end fences 21C and 22C, the assembly is further facilitated and the upper collars 21B and 22B. Since the sealing material 50 is continuous even in the corner portions of the door-end lamps 21C and 22C, it is possible to reliably suppress the sound from entering from the outdoor side to the indoor side even in the corner portion, and the heat insulation is excellent.

さらに、戸先框２１Ｃ，２２Ｃに取付けられたシール材５０の取付基部５１には、障子２１，２２の閉時にサッシ枠１０に突設されたフランジＦ２の先端に直接当接する緩衝用のスポンジ材Ｓが設けられているので、障子２１，２２を閉めるときの位置決め用のストッパーとして機能するとともに、フランジＦ２の先端が底突きするとき発生する音を効果的に抑制する。
また、障子２１，２２の閉鎖時には、サッシ枠１０から延びるフランジＦ１，Ｆ２は、その側面が、室外側リップ部５２及び室内側リップ部５３でシールされるとともに縦枠１３，１４においてはフランジＦ２の先端もスポンジ材Ｓでシールされる構成であり、計３点が面によってシールされるので、遮音性は向上し断熱性にも優れる。特に室外側リップ部５２及び室内側リップ５３はソリッド材で形成されているので、障子２１，２２の開閉性を特に悪くすることなく、スポンジ材Ｓと相俟ってシール性を高めることができる。 Further, the mounting base portion 51 of the sealing material 50 attached to the door rods 21C and 22C has a cushioning sponge material that directly contacts the tip of the flange F2 protruding from the sash frame 10 when the shoji 21 and 22 are closed. Since S is provided, it functions as a positioning stopper when closing the shojis 21 and 22, and effectively suppresses the sound generated when the tip of the flange F2 bottoms out.
When the shojis 21 and 22 are closed, the side surfaces of the flanges F1 and F2 extending from the sash frame 10 are sealed by the outdoor lip portion 52 and the indoor lip portion 53, and the flanges F2 in the vertical frames 13 and 14 are sealed. The tip is also sealed with the sponge material S, and a total of three points are sealed by the surface, so that the sound insulation is improved and the heat insulation is excellent. In particular, since the outdoor lip portion 52 and the indoor lip 53 are formed of a solid material, the sealing performance can be enhanced in combination with the sponge material S without particularly deteriorating the opening / closing performance of the shojis 21 and 22. .

なお、本発明の実施形態では、シール材５０を障子２１，２２の上框２１Ｂ，２２Ｂ及び戸先框２１Ｃ，２２Ｃの両方に沿って取付けるようにしたが、障子２１，２２の上框２１Ｂ，２２Ｂのみ、あるいは、障子２１，２２の戸先框２１Ｃ，２２Ｃのみに取付ける構成にすることも可能である。
また、フランジＦ２の先端に当接するスポンジ材Ｓをシール材５０の取付基部５１に設けるようにしたが、スポンジ材Ｓを特に設けることなく、障子２１，２２の閉鎖時にフランジＦ１，Ｆ２の先端を取付基部５１の底壁部５１ｃに直接底突きさせ、底壁部５１ｃをストッパーとして機能させることも可能である。これによれば、スポンジ材Ｓなどの位置決め部材を別に用意する必要がないので、部品点数がさらに減り、一層、シール材５０の組み付けが容易になるとともにコストの削減となる。 In the embodiment of the present invention, the seal member 50 is attached along both the upper collars 21B and 22B of the shojis 21 and 22 and the door-end fences 21C and 22C. It is also possible to adopt a configuration that attaches only to 22B or only to the door toe doors 21C and 22C of the shoji 21 and 22.
Further, the sponge material S that contacts the tip of the flange F2 is provided on the mounting base 51 of the seal material 50. However, without providing the sponge material S, the tips of the flanges F1 and F2 are closed when the shoji 21 and 22 are closed. It is also possible to cause the bottom wall portion 51c of the mounting base portion 51 to directly bottom so that the bottom wall portion 51c functions as a stopper. According to this, since it is not necessary to separately prepare a positioning member such as the sponge material S, the number of parts is further reduced, and the assembly of the seal material 50 is further facilitated and the cost is further reduced.

また、本発明の実施形態では、スポンジ材Ｓを、戸先框２１Ｃ，２２Ｃにおいて上下２ケ所に設けたが、シール材５０の取付基部５１と同様に戸先框２１Ｃ，２２Ｃに沿って上下に連続的に設けることもでき、これによれば遮音性はさらに向上し、断熱効果も向上する。   Further, in the embodiment of the present invention, the sponge material S is provided at two places on the top and bottom of the door toe 21C and 22C. However, like the mounting base 51 of the seal material 50, the sponge material S is vertically moved along the door toe 21C and 22C. It can also be provided continuously, and according to this, the sound insulation is further improved and the heat insulation effect is also improved.

さらに、図７及び図８に示すように、戸先框２１Ｃ，２２Ｃに取付けられるシール材５０の断面形状を変えて、スポンジ材Ｓの位置を、フランジＦ２の先端が直接的にスポンジ材Ｓに当接しないようにすることもできる。
すなわち、図７（ａ）に示すものは、シール材５０の取付基部５１の室外側側壁部５１ａから、フランジＦ２の先端に当接する部位５１ｄを突設し、その突設した部位５１ｄと取付基部５１の底壁部５１ｃとの間に、スポンジ材Ｓを設けたものである。突設した部位５１ｄにフランジＦ２の先端が当接すると突設した部位５１ｄはスポンジ材Ｓを圧縮させるのでスポンジ材Ｓは緩衝機能を果たす。先端に当接する部位５１ｄは、室内側側壁部５１ｂから突設されるものであってもよく、図７（ｂ）に示すように、シール材５０の取付基部５１の底壁部５１ｃから、フランジＦ２の先端に当接する部位５１ｄが突設されるものであってもよい。底壁部５１ｃから突設されるものは、底壁部５１ｃからフランジＦ２側に略平行（或いは略平行でなくてもよい）に延び室内側側壁部５１ｂ側（図７（ｂ））あるいは室外側側壁部５１ａ側に略垂直（或いは略垂直でなくてもよい）に折れ曲がった断面略鉤状である。また、図７（ｂ）のように直角状に折れ曲がるだけでなく、円弧を描きながら折れ曲がっていてもよい。さらに、底壁部５１ｃから突設する場合は、断面略鉤状に限定されず、底壁部５１ｃから室内側側壁部５１ｂあるいは室外側側壁部５１ａ側で、且つフランジＦ２側に傾斜したヒレ状であってもよい。
また、図８に示すものは、シール材５０の取付基部５１の底壁部５１ｃを部分的に、ここでは略中央部分を内方に突出させて、フランジＦ２の先端に当接する部位である凸部５１ｅとするともに、外方側に形成される凹部５１ｆに、スポンジ材Ｓを設けたものである。内方に突出させた凸部５１ｅにフランジＦ２の先端が当接するとその凸部５１ｅはスポンジ材Ｓを圧縮させるのでスポンジ材Ｓは緩衝機能を果たす。
これによれば、スポンジ材ＳはフランジＦ２の先端に直接に当接しないので、スポンジ材Ｓは破れ難く、長期的に使用することができる。
また、スポンジ材Ｓは、図３，図７，図８のように中実状であってもよく、空間を有する中空状であってもよい。 Further, as shown in FIGS. 7 and 8, the cross-sectional shape of the seal material 50 attached to the door rods 21C and 22C is changed to change the position of the sponge material S so that the tip of the flange F2 is directly connected to the sponge material S. It is also possible not to make contact.
That is, in FIG. 7A, a portion 51d that abuts against the tip of the flange F2 is projected from the outdoor side wall portion 51a of the mounting base 51 of the sealing material 50, and the protruding portion 51d and the mounting base are provided. The sponge material S is provided between the bottom wall portion 51c of 51. When the tip of the flange F2 comes into contact with the projecting part 51d, the projecting part 51d compresses the sponge material S, so that the sponge material S functions as a buffer. The part 51d in contact with the tip may protrude from the indoor side wall 51b, and as shown in FIG. 7 (b), from the bottom wall 51c of the mounting base 51 of the sealing material 50 to the flange. A portion 51d that abuts on the tip of F2 may be projected. What protrudes from the bottom wall 51c extends substantially parallel (or may not be substantially parallel) from the bottom wall 51c to the flange F2 side, or on the indoor side wall 51b side (FIG. 7 (b)) or the chamber. The cross section is substantially bowl-shaped and bent substantially perpendicularly (or may not be substantially perpendicular) to the outer side wall 51a side. In addition to being bent at a right angle as shown in FIG. 7B, it may be bent while drawing an arc. Furthermore, when projecting from the bottom wall portion 51c, it is not limited to a substantially bowl-shaped cross section, but is a fin shape inclined from the bottom wall portion 51c to the indoor side wall portion 51b or the outdoor side wall portion 51a and to the flange F2 side. It may be.
Further, in FIG. 8, the bottom wall portion 51c of the mounting base portion 51 of the sealing material 50 is partially protruded, and here, a substantially central portion protrudes inward, and is a convex portion that is a portion that comes into contact with the tip of the flange F2. In addition to the portion 51e, a sponge material S is provided in a recess 51f formed on the outer side. When the tip of the flange F2 comes into contact with the projecting portion 51e projecting inwardly, the projecting portion 51e compresses the sponge material S, so that the sponge material S functions as a buffer.
According to this, since the sponge material S does not directly contact the tip of the flange F2, the sponge material S is not easily broken and can be used for a long time.
Further, the sponge material S may be solid as shown in FIGS. 3, 7, and 8, or may be hollow with a space.
