気密部材６の具体的な構造について、さらに図７、図８及び図９を用いて説明する。本実施形態の気密部材６は、気密部材本体６１と、複数枚の板状片６２と、引き寄せ部材７と、によって構成される。これらの気密部材本体６１、板状片６２及び引き寄せ部材７は、軟質樹脂材によって一体に成形されている。 The specific structure of the airtight member 6 will be further described with reference to FIGS. 7, 8 and 9. The airtight member 6 of the present embodiment is composed of an airtight member main body 61, a plurality of plate-shaped pieces 62, and an attracting member 7. The airtight member main body 61, the plate-shaped piece 62, and the pulling member 7 are integrally molded of a soft resin material.

気密部材本体６１は、下枠２２の室外側レール２２１と室内側レール２２２とに亘る大きさを有するブロック状に形成される。気密部材本体６１は、図６に示すように、室外側レール２２１よりも低い位置に配置される。しかし、気密部材本体６１の上面６１ａは、外障子３及び内障子４の開閉動作に支障がない程度に、外障子３及び内障子４に近接するように配置されている。 The airtight member main body 61 is formed in a block shape having a size extending over the outdoor side rail 221 and the indoor side rail 222 of the lower frame 22. As shown in FIG. 6, the airtight member main body 61 is arranged at a position lower than the outdoor rail 221. However, the upper surface 61a of the airtight member main body 61 is arranged so as to be close to the outer sash 3 and the inner sash 4 so as not to interfere with the opening / closing operation of the outer sash 3 and the inner sash 4.

気密部材本体６１の室内側端面６１ｂには、２つの係合凸部６１１，６１１が設けられる。気密部材６は、係合凸部６１１，６１１を、下枠２２の室内側レール２２２に設けられる２つの係合穴２２２ａ，２２２ａに対してそれぞれ室外側から挿入することによって、下枠２２の上面２２ａに取り付けられる。 Two engaging protrusions 611 and 611 are provided on the indoor side end surface 61b of the airtight member main body 61. The airtight member 6 inserts the engaging protrusions 611 and 611 into the two engaging holes 222a and 222a provided in the indoor side rail 222 of the lower frame 22 from the outdoor side, respectively, thereby inserting the upper surface of the lower frame 22 from the outdoor side. It is attached to 22a.

複数の板状片６２は、気密部材本体６１の上面６１ａにおける室内側に、上方に向けて突出して設けられる。詳しくは、複数の板状片６２は、気密部材本体６１の上面６１ａの室内側の端部付近に、面方向が室内外方向に沿い、且つ下枠２２の延び方向に所定の間隔をおいて平行に配置される。板状片６２は、図６に示すように、内障子４の内召し合わせ框４４の下端部４４ｂとオーバーラップする高さを有している。そのため、板状片６２は、開閉移動する内障子４の内召し合わせ框４４の下端部４４ｂと接触する。このとき、板状片６２は、下枠２２の延び方向に沿って倒れるように弾性的に変形して重なり合う。これによって、複数の板状片６２は、閉位置に配置される内召し合わせ框４４の係合溝４ｂにおける室内側レール２２２よりも室外側の部位を塞ぎ、気密性を確保する。 The plurality of plate-shaped pieces 62 are provided on the indoor side of the upper surface 61a of the airtight member main body 61 so as to project upward. Specifically, the plurality of plate-shaped pieces 62 are arranged in the vicinity of the indoor end of the upper surface 61a of the airtight member main body 61 in the indoor / outdoor direction and at predetermined intervals in the extending direction of the lower frame 22. Arranged in parallel. As shown in FIG. 6, the plate-shaped piece 62 has a height that overlaps with the lower end portion 44b of the inner sash 44 of the internal sash 4. Therefore, the plate-shaped piece 62 comes into contact with the lower end portion 44b of the inner sash 44 of the internal shoji 4 that moves open and close. At this time, the plate-shaped pieces 62 are elastically deformed and overlapped with each other so as to fall down along the extending direction of the lower frame 22. As a result, the plurality of plate-shaped pieces 62 close the portion outside the indoor side rail 222 in the engaging groove 4b of the inner mating stile 44 arranged at the closed position to ensure airtightness.

引き寄せ部材７は、気密部材本体６１の上面６１ａにおける室外側の端部に、上方に向けて突出して設けられる。詳しくは、引き寄せ部材７は、図６及び図７に示すように、気密部材本体６１の上面６１ａから、室外側レール２２１の室内側面２２１ｂに沿って上方に延びる小さなブロック片からなる。引き寄せ部材７は、室外側レール２２１の室内側面２２１ｂに密接している。引き寄せ部材７の上端面７１は、室外側レール２２１の上端よりも低い位置に配置される。そのため、外障子３の戸車３７が室外側レール２２１に沿って転動する際に支障が生じることはない。 The pulling member 7 is provided at the outdoor end of the upper surface 61a of the airtight member main body 61 so as to project upward. Specifically, as shown in FIGS. 6 and 7, the pulling member 7 is composed of a small block piece extending upward from the upper surface 61a of the airtight member main body 61 along the indoor side surface 221b of the outdoor rail 221. The pulling member 7 is in close contact with the indoor side surface 221b of the outdoor side rail 221. The upper end surface 71 of the pulling member 7 is arranged at a position lower than the upper end of the outdoor rail 221. Therefore, there is no problem when the door roller 37 of the shoji 3 rolls along the outdoor rail 221.

引き寄せ部材７は、図７、図８及び図９に示すように、室外側レール２２１の室内側面２２１ｂから室内側に向けて最も突出する室内側端面７２を有する。この室内側端面７２は、室外側レール２２１の室内側面２２１ｂに対して略平行に配置される。この室内側端面７２の左右両側部には、それぞれ室内側端面７２から室外側レール２２１の室内側面２２１ｂに向けて傾斜する傾斜面７３，７３が設けられる。 As shown in FIGS. 7, 8 and 9, the pulling member 7 has an indoor side end surface 72 that protrudes most toward the indoor side from the indoor side surface 221b of the outdoor side rail 221. The indoor side end surface 72 is arranged substantially parallel to the indoor side surface 221b of the outdoor side rail 221. Inclined surfaces 73 and 73 inclined from the indoor side end surface 72 toward the indoor side surface 221b of the outdoor side rail 221 are provided on the left and right side portions of the indoor side end surface 72, respectively.

室外側レール２２１の室内側面２２１ｂから室内側へ向かう引き寄せ部材７の突出量、すなわち、室外側レール２２１の室内側面２２１ｂから引き寄せ部材７の室内側端面７２までの距離は、外障子３の下框３２の係合溝３ｂにおける室内側の開口縁３ｂ１（図５参照）と、室外側レール２２１の室内側面２２１ｂとの隙間の大きさよりは小さい。しかし、この距離は、外障子３の外召し合わせ框３４の下端部３４ｂにおいて室外側レール２２１を挟み込んでいる樹脂部品３４４の室内側の開口縁３４４ｂ（図５参照）と、室外側レール２２１の室内側面２２１ｂとの隙間の大きさよりも僅かに大きい。 The amount of protrusion of the pulling member 7 from the indoor side surface 221b of the outdoor side rail 221 toward the indoor side, that is, the distance from the indoor side surface 221b of the outdoor side rail 221 to the indoor side end surface 72 of the pulling member 7 is the lower frame of the outer sash 3. It is smaller than the size of the gap between the opening edge 3b1 (see FIG. 5) on the indoor side in the engaging groove 3b of 32 and the indoor side surface 221b of the outdoor side rail 221. However, this distance is set between the opening edge 344b (see FIG. 5) on the indoor side of the resin component 344 sandwiching the outdoor rail 221 at the lower end 34b of the outer mating frame 34 of the outer sash 3 and the outdoor rail 221. It is slightly larger than the size of the gap with the indoor side surface 221b.

次に、この引き寄せ部材７の作用及び効果について説明する。外障子３の外召し合わせ框３４が開位置から閉位置に向けて移動すると、外召し合わせ框３４の下端部３４ｂの樹脂部品３４４の室内側の開口縁３４４ｂが、まず、傾斜面７３に当接する。室外側レール２２１の室内側面２２１ｂから引き寄せ部材７の室内側端面７２までの距離は、外障子３の下框３２の係合溝３ｂにおける室内側の開口縁３ｂ１（図５参照）と、室外側レール２２１の室内側面２２１ｂとの間の隙間の大きさよりも小さいため、外障子３の移動時に、下框３２の係合溝３ｂが引き寄せ部材７と干渉することはなく、外障子３の開閉動作が重くなることはない。 Next, the action and effect of the attracting member 7 will be described. When the outer sash 34 of the outer sash 3 moves from the open position to the closed position, the opening edge 344b on the indoor side of the resin part 344 of the lower end 34b of the outer sash 34 first hits the inclined surface 73. Contact. The distance from the indoor side surface 221b of the outdoor side rail 221 to the indoor side end surface 72 of the pulling member 7 is the opening edge 3b1 (see FIG. 5) on the indoor side in the engaging groove 3b of the lower frame 32 of the outer sash 3 and the outdoor side. Since it is smaller than the size of the gap between the rail 221 and the indoor side surface 221b, the engaging groove 3b of the lower stile 32 does not interfere with the pulling member 7 when the outer sash 3 is moved, and the outer sash 3 is opened and closed. Does not become heavy.

外召し合わせ框３４がさらに閉位置に向けて移動すると、樹脂部品３４４の室内側の開口縁３４４ｂは、傾斜面７３に沿って室内側に向けて次第に案内される。これによって、外召し合わせ框３４は、図６中の白抜き矢印に示すように、室内側に向けて徐々に引き寄せられる。外障子３が閉位置に停止すると、樹脂部品３４４の室内側の開口縁３４４ｂは、引き寄せ部材７の室内側端面７２に配置され、室内側に向けて最も引き寄せられる。そのため、樹脂部品３４４の室外側の開口縁３４４ａが、室外側から室外側レール２２１の室外側面２２１ａに向けて確実に密接する。したがって、クレセント錠４８の施錠によって外召し合わせ框３４を内召し合わせ框４４に引き寄せて気密性を向上させることに加えて、外障子３の外召し合わせ框３４の下端部３４ｂにおいても気密性を向上させることができる。 When the outside stile 34 is further moved toward the closed position, the opening edge 344b on the indoor side of the resin component 344 is gradually guided toward the indoor side along the inclined surface 73. As a result, the outside stile 34 is gradually pulled toward the indoor side as shown by the white arrow in FIG. When the outer sash 3 is stopped at the closed position, the opening edge 344b on the indoor side of the resin component 344 is arranged on the indoor end surface 72 of the attracting member 7 and is most attracted toward the indoor side. Therefore, the opening edge 344a on the outdoor side of the resin component 344 is surely brought into close contact with the outdoor side surface 221a of the outdoor side rail 221 from the outdoor side. Therefore, in addition to improving the airtightness by attracting the outer-sealing stile 34 to the inner-sealing stile 44 by locking the crescent lock 48, the lower end portion 34b of the outer-sealing stile 34 of the shoji 3 is also airtight. Can be improved.

引き寄せ部材７は、下枠２２の室外側レール２２１の室内側面２２１ｂから室内側に向けて突出するように配置され、閉位置に向けて移動する外障子３の外召し合わせ框３４に当接することによって、外障子３の外召し合わせ框３４を次第に室内側に向けて案内する傾斜面７３を有する。そのため、外障子３の外召し合わせ框３４の下端部３４ｂは、引き寄せ部材７の室内側端面７２に向けて円滑に案内される。 The pulling member 7 is arranged so as to project toward the indoor side from the indoor side surface 221b of the outdoor side rail 221 of the lower frame 22, and abuts on the outer sash 34 of the outer sash 3 moving toward the closed position. As a result, it has an inclined surface 73 that gradually guides the outside-combining stile 34 of the outside shoji 3 toward the indoor side. Therefore, the lower end portion 34b of the outer mating stile 34 of the outer sash 3 is smoothly guided toward the indoor side end surface 72 of the pulling member 7.

引き寄せ部材７は、気密部材６に一体に設けられているため、気密部材６を下枠２２に取り付けるだけで、気密部材６による内召し合わせ框４４の下端部４４ｂの気密性を向上させる効果に加えて、引き寄せ部材７による外召し合わせ框３４の下端部３４ｂの気密性を向上させる効果を容易に得ることができる。 Since the pulling member 7 is integrally provided with the airtight member 6, simply attaching the airtight member 6 to the lower frame 22 has the effect of improving the airtightness of the lower end portion 44b of the inner mating stile 44 by the airtight member 6. In addition, the effect of improving the airtightness of the lower end portion 34b of the outer mating stile 34 by the pulling member 7 can be easily obtained.

以上の実施形態に示す引き寄せ部材７は、気密部材６の気密部材本体６１に一体に成形されている。しかし、引き寄せ部材７は、図１０に示すように、気密部材６とは別体に形成され、下枠２２の室外側レール２２１の室内側面２２１ｂに、両面接着テープ、係合穴と係合凸部とによる係合等の適宜の固定手段によって取り付けられてもよい。これによって、気密部材６が取り付けられた既設の下枠２２に、引き寄せ部材７を後付けすることができる。 The pulling member 7 shown in the above embodiment is integrally molded with the airtight member main body 61 of the airtight member 6. However, as shown in FIG. 10, the pulling member 7 is formed separately from the airtight member 6, and has a double-sided adhesive tape, an engaging hole and an engaging convex on the indoor side surface 221b of the outdoor side rail 221 of the lower frame 22. It may be attached by an appropriate fixing means such as engagement with a portion. As a result, the pulling member 7 can be retrofitted to the existing lower frame 22 to which the airtight member 6 is attached.

図１１及び図１２は、第２実施形態に係る引き寄せ部材８を示している。図７及び図８に示される第１実施形態に係る引き寄せ部材７を有する気密部材６と同一符号の部位は、同一構成の部位を示している。それらの詳細な説明は上記説明を援用し、以下においては省略する。 11 and 12 show the pulling member 8 according to the second embodiment. A portion having the same reference numeral as the airtight member 6 having the attracting member 7 according to the first embodiment shown in FIGS. 7 and 8 indicates a portion having the same configuration. The detailed explanations thereof refer to the above explanations and are omitted below.

引き寄せ部材８は、気密部材本体６１の上面６１ａにおける室外側の端部に、上方に向けて突出して設けられる複数の板状部材８１からなる。板状部材８１は、それぞれ軟質樹脂によって気密部材本体６１の上面６１ａに一体に成形されている。各板状部材８１は、気密部材本体６１の上面６１ａから、室外側レール２２１の室内側面２２１ｂに沿って上下方向に延びており、室外側レール２２１の延び方向に沿って、間隔をあけて並んで設けられている。板状部材８１は、室外側レール２２１の室内側面２２１ｂにそれぞれ密接している。板状部材８１は、それぞれ室外側レール２２１の上端よりも低い位置に配置されるため、外障子３の戸車３７が室外側レール２２１に沿って転動する際に支障が生じることはない。 The pulling member 8 is composed of a plurality of plate-shaped members 81 provided so as to project upward at the outdoor end of the upper surface 61a of the airtight member main body 61. Each of the plate-shaped members 81 is integrally molded with a soft resin on the upper surface 61a of the airtight member main body 61. Each plate-shaped member 81 extends vertically from the upper surface 61a of the airtight member main body 61 along the indoor side surface 221b of the outdoor rail 221 and is arranged at intervals along the extending direction of the outdoor rail 221. It is provided in. The plate-shaped member 81 is in close contact with the indoor side surface 221b of the outdoor side rail 221. Since each of the plate-shaped members 81 is arranged at a position lower than the upper end of the outdoor rail 221, there is no problem when the door roller 37 of the shoji 3 rolls along the outdoor rail 221.

各板状部材８１は、室外側レール２２１の室内側面２２１ｂから室内側に向けて同一の突出高さを有している。板状部材８１は、外障子３の框体３０と接触した際に容易に撓むことができるため、各板状部材８１の室内側に向けた突出高さは、外障子３の下框３２の係合溝３ｂにおける室内側の開口縁３ｂ１（図５参照）と、室外側レール２２１の室内側面２２１ｂとの隙間の大きさと同等以上であってもよい。これによって、板状部材８１からなる引き寄せ部材８であっても、外障子３の外召し合わせ框３４と当接した際には、引き寄せ部材７と同様に、外召し合わせ框３４を室内側に向けて引き寄せることができる。 Each plate-shaped member 81 has the same protruding height from the indoor side surface 221b of the outdoor side rail 221 toward the indoor side. Since the plate-shaped member 81 can be easily bent when it comes into contact with the frame 30 of the outer sash 3, the protruding height of each plate-shaped member 81 toward the indoor side is the lower stile 32 of the outer sash 3. The size of the gap between the indoor side opening edge 3b1 (see FIG. 5) in the engaging groove 3b and the indoor side surface 221b of the outdoor side rail 221 may be equal to or larger than the size of the gap. As a result, even in the pulling member 8 made of the plate-shaped member 81, when the pulling member 8 comes into contact with the outer mating stile 34 of the outer shoji 3, the outer mating stile 34 is moved to the indoor side in the same manner as the pulling member 7. Can be drawn towards.

板状部材８１の室内側へ向けたそれぞれの突出高さは、図１３に示すように異ならせてもよい。詳しくは、室外側レール２２１の室内側面２２１ｂから室内側に向けた板状部材８１のそれぞれの突出高さは、板状部材８１の並び方向の両端部に配置される板状部材８１ａ，８１ａから室外側レール２２１の延び方向の中央Ｃ側に配置される板状部材８１ｂ，８１ｂに向かうに従って次第に増大している。これによれば、引き寄せ部材８は、外障子３が閉位置に近づくに従って、外召し合わせ框３４に対して次第に室内側に向けて引き寄せる力を大きくすることができるため、より確実に外召し合わせ框３４を室内側に引き寄せることができる。 The protruding heights of the plate-shaped members 81 toward the indoor side may be different as shown in FIG. Specifically, the protruding heights of the plate-shaped members 81 from the indoor side surface 221b of the outdoor side rail 221 toward the indoor side are from the plate-shaped members 81a and 81a arranged at both ends in the arrangement direction of the plate-shaped members 81. The number gradually increases toward the plate-shaped members 81b and 81b arranged on the center C side in the extending direction of the outdoor rail 221. According to this, as the outer sash 3 approaches the closed position, the pulling member 8 can gradually increase the pulling force toward the indoor side with respect to the outer sash stile 34, so that the outer sash member 8 can be sewn more reliably. The stile 34 can be pulled toward the room side.

図１１、図１２及び図１３に示した引き寄せ部材８は、６つの板状部材８１によって構成されている。しかし、引き寄せ部材８を構成する板状部材８１は、少なくとも１つあればよい。引き寄せ部材８は、図１０に示した引き寄せ部材７と同様に、気密部材６と別体に構成され、室外側レール２２１の室内側面２２１ｂに取り付けられてもよい。 The pulling member 8 shown in FIGS. 11, 12 and 13 is composed of six plate-shaped members 81. However, the number of plate-shaped members 81 constituting the attracting member 8 may be at least one. Similar to the pulling member 7 shown in FIG. 10, the pulling member 8 may be configured separately from the airtight member 6 and may be attached to the indoor side surface 221b of the outdoor side rail 221.

以上説明した引き寄せ部材７，８を有する気密部材６及び引き寄せ部材７，８は、上枠２１に設けられてもよい。引き寄せ部材７，８を有する気密部材６及び引き寄せ部材７，８が上枠２１と下枠２２にそれぞれ設けられる場合は、外障子３の外召し合わせ框３４の上端部３４ａと下端部３４ｂの両方の気密性を向上させることができる。この場合は、特に、引違い窓１が、床面から天井までの高さを有する大きな高さ寸法を有していても、外召し合わせ框３４及び内召し合わせ框４４の重ね合わせ部位における気密性を高めることができる。 The airtight member 6 having the attracting members 7 and 8 and the attracting members 7 and 8 described above may be provided on the upper frame 21. When the airtight member 6 having the pulling members 7 and 8 and the pulling members 7 and 8 are provided on the upper frame 21 and the lower frame 22, respectively, both the upper end portion 34a and the lower end portion 34b of the outer mating stile 34 of the outer sash 3 are provided. Can improve the airtightness of. In this case, in particular, even if the sliding window 1 has a large height dimension having a height from the floor surface to the ceiling, the airtightness at the overlapping portion of the outer merging stile 34 and the inner merging stile 44 is particularly high. It can enhance the sex.
