This fixture is a raising and lowering window installed in a window opening of a house, and as shown in FIGS. 1 to 4, it is arranged on the upper side of the frame 1 fixed to the housing opening and the outdoor side in the frame 1 It includes an outer shell 4, an inner shell 2 disposed on the lower side of the indoor side in the frame 1, and left and right balancers 3, 3 installed in the frame 1. The outer gutter 4 is a fixed glide fixed to the frame 1. The inner seal 2 is a movable outer seal that slides up and down along the vertical frames 5 and 5. As shown in FIG. 4, the inner scissor 2 is suspended by wires 6 and 6 extending from the balancers 3 and 3, and can slide up and down with a light force and can stop at any height position. . In addition, the inner scissor 2 has latches 7, 7 engaged with the vertical frames 5, 5 on the left and right sides of the upper part, and can be turned indoors as shown in FIG. 6 by releasing the latches 7, 7. Yes, and this makes it possible to clean the inner shingles 2 easily. The side portions of the internal seal 2 and the vertical frames 5 and 5 are connected by arms 8 and 8, and the arms 8 and 8 regulate the falling angle of the internal seal 2.

枠1は、上枠9と下枠10と左右の縦枠5,5を枠組みして構成される。上枠9は、図1に示すように、外周側部材11と内周側部材12の2部材で構成してある。外周側部材11は、アルミニウム合金の押出形材で形成してある。内周側部材12は、合成樹脂の押出形材よりなり、外障子4の上框13の室内側に配置され、上枠9の室内側から見える部分を被っている。内周側部材12は、室外側と室内側の2箇所に係止部14a,14bを有し、その係止部14a,14bを外周側部材11に係止して取付けられている。内周側部材12は、室内側に額縁15にネジ止めされるアングル部16を有し、アングル部16の室外側に底壁17がアングル部16と面一に形成されおり、また底壁17は外周側部材11の室外側端部に形成された垂下片18の下端と略同じ高さ位置にある。底壁17の室外側端部には、柔軟なヒレ片19が室外側に突出して形成され、ヒレ片19の先端部が外障子4の上框13の室内側に当接している。内周側部材12は、内部が複数の中空部20a,20b,20c,20dに仕切られており、これにより断熱性を高めている。内周側部材12は、バランサー3,3を上枠9内にのみ込ませるため、図9(a)に示すように、左右両端部にアングル部16を残すようにしてL字形に切り欠き21が設けてある。   The frame 1 is configured by framing an upper frame 9, a lower frame 10, and left and right vertical frames 5, 5. The upper frame 9 is comprised by two members, the outer peripheral side member 11 and the inner peripheral side member 12, as shown in FIG. The outer peripheral side member 11 is formed of an extruded shape of an aluminum alloy. The inner peripheral side member 12 is made of an extruded material of a synthetic resin, is disposed on the indoor side of the upper collar 13 of the outer shutter 4 and covers a portion visible from the indoor side of the upper frame 9. The inner circumferential side member 12 has locking portions 14a and 14b at two locations, the outdoor side and the indoor side, and the locking portions 14a and 14b are locked to the outer circumferential side member 11 and attached.

A flexible fin piece 19 is formed on the outdoor side end of the bottom wall 17 so as to project outward, and the tip end of the fin 19 abuts against the indoor side of the upper collar 13 of the outer shell 4. The inner peripheral side member 12 is divided into a plurality of hollow portions 20a, 20b, 20c, and 20d inside, thereby enhancing the heat insulation. In order to fit the balancers 3 and 3 only into the upper frame 9, the inner circumferential side member 12 has an L-shaped notch 21 so that the angle portions 16 are left at the left and right ends as shown in FIG. It is provided.

上枠9の内周側部材12は、図20に示すように、アングル部16を別体で形成することもできる。この場合、内周側部材12の左右の側縁12aをまっすぐに切断するだけで、バランサー3の上部をのみ込ませるための孔を形成でき、図9(a)に示すようなL字形の切り欠き21が不要となるので、加工コストを抑えられる。また、アングル部16を額縁15に取付けたまま内周側部材12を取外すことができるので、メンテナンス性が向上する。   The inner peripheral side member 12 of the upper frame 9 can also be formed separately as the angle part 16 as shown in FIG. In this case, by simply cutting the left and right side edges 12a of the inner peripheral side member 12 straight, a hole for inserting the upper part of the balancer 3 can be formed, and an L-shaped notch as shown in FIG. Since 21 is unnecessary, processing cost can be held down. Further, since the inner circumferential side member 12 can be removed while the angle portion 16 is attached to the frame 15, the maintainability is improved.

縦枠5は、図2に示すように、外周側部材22と内周側部材23とアングル材39とを有している。外周側部材22はアルミニウム合金の押出形材よりなり、内周側部材23とアングル材39は合成樹脂の押出形材よりなる。

The tight material 25 provided between the vertical frames 5 and 5 and provided on the outer peripheral portion of the outdoor side surface of the outer shutter 4 is in contact with the indoor side of the foremost portion of the viewing wall 24. As described above, by enabling the erector 4 to be erected straight from the indoor side, it has conventionally been necessary when erecting the erector 4 laterally between the vertical frames 5 and 5 Since the transfer space is not required, the size of the vertical frame 5 can be reduced, and as a result, the lighting area and the opening area increase in the left-right direction. A rectangular hollow portion 26 is provided on the indoor side of the finding wall 24.

縦枠5の内周側部材23は、図2に示すように、外周側部材22の中空部26の室内側に内周側から係合させて取付けてある。内周側部材23は、図1,9に示すように、バランサー3より下方に設けてある。すなわち、内周側部材23の上部を外周側部材22よりも短く、フラットに切断することにより、内周側部材23の上端と上枠9の下面間にバランサー3の取付けスペース27を確保している。
内周側部材23は、図2に示すように、室内側に外周側に凹んだ凹部28が形成されている。凹部28の底部は、内障子2を吊るワイヤー6の挿通部29となっている。ワイヤー挿通部29の内周側の室外側と室内側の壁には、内向き突部30a,30bがそれぞれ設けてあり、図3に示すように、内障子2の下部に外周側に突設したロッド棒31が内向き突部30a,30b間に案内されている。ロッド棒31には、ワイヤー6の下端部が係止している。凹部28の室外側は、複数の中空部32a,32b,32c,32dに仕切られている。
図2に示すように、室外側の内向き突部30aの内周側には鉤型の係止片33が形成してあり、係止片33のさらに内周側には室内側が開口した室外ガイド溝34aを有している。係止片33と室内側の内向き突部間30b間には、樹脂製の目板35が取付けてある。目板35は、図6に示すように、バランサー3の下から内障子2の上框36と重合する高さ位置にわたって設けてあり、ワイヤー挿通部29は目板35に隠れて見えなくしてある。なお目板35は、図18に示すように、室外側端部に形成した係止部37を縦枠5の係止片33に係止し、その係止部37を支点として外周側に回転させることで、室内側端部に形成した係止片38が縦枠5の内向き突部30bに弾発的に係止して取付けられる。目板35を取外す際は、図6に示すように、内障子2を内倒しした状態で、目板35の下端に指を差し入れて内周側に引っ張ればよい。
As shown in FIG. 2, the inner peripheral side member 23 of the vertical frame 5 is engaged with and attached to the indoor side of the hollow portion 26 of the outer peripheral side member 22 from the inner peripheral side. The inner circumferential side member 23 is provided below the balancer 3 as shown in FIGS.

The outdoor side of the recess 28 is divided into a plurality of hollow portions 32a, 32b, 32c, 32d.
As shown in FIG. 2, a hook-shaped locking piece 33 is formed on the inner peripheral side of the inward projection 30 a on the outdoor side, and the indoor side is open on the inner peripheral side of the locking piece 33. It has a guide groove 34a. A resin-made eye plate 35 is attached between the locking piece 33 and the inward projection 30b on the indoor side. As shown in FIG. 6, the eye plate 35 is provided from below the balancer 3 to a height position overlapping with the upper collar 36 of the inner gutter 2, and the wire insertion portion 29 is hidden behind the eye plate 35 and is invisible. . Note that, as shown in FIG. 18, the eye plate 35 locks the locking portion 37 formed at the outdoor end to the locking piece 33 of the vertical frame 5, and rotates around the locking portion 37 as a fulcrum As a result, the locking piece 38 formed at the indoor end is resiliently locked and attached to the inward projection 30 b of the vertical frame 5. When removing the eye plate 35, as shown in FIG. 6, it is sufficient to insert a finger at the lower end of the eye plate 35 and pull it on the inner circumferential side in a state in which the inner seal 2 is turned inward.

図2,3に示すように、内周側部材23の室内側には、アングル材39が取付けてある。アングル材39は、外周側部材22と内周側部材23とに形成された係止溝40a,40bに内周側から係止片41a,41bをそれぞれ係止して取付けられる。アングル材39は、合成樹脂の押出形材よりなり、額縁15にネジ止めされるアングル部42と、内周側部材23の室内側壁に沿って内周側にのびる見付部43を一体に有している。見付部43は中空状に形成してある。見付部43の内周側端部には、室外側が開口した室内ガイド溝34bを有している。室内ガイド溝34bは、内周側部材23に形成された室外ガイド溝34aと対向して設けてあり、図3に示すように、室外ガイド溝34aと室内ガイド溝34bとで挟持する形で、内障子2の内倒し角度を規制するアーム8が連結されたスライダー44が上下方向に摺動可能に案内してある。また、室内ガイド溝34bの内周側端部45は、図2に示すように、内障子2の上部に取付けられたラッチ7の爪46の摺動部になっている。図9に示すように、内周側部材23はバランサーの下で切断されている一方で、アングル材39は上枠9の下面までのびている。縦枠5の内周側部材23とアングル材39は、取外し可能となっている。   As shown in FIGS. 2 and 3, an angle member 39 is attached to the indoor side of the inner peripheral side member 23. The angle members 39 are attached to the locking grooves 40a and 40b formed in the outer peripheral side member 22 and the inner peripheral side member 23, respectively, by locking the locking pieces 41a and 41b from the inner peripheral side. The angle member 39 is made of an extruded material of synthetic resin, and integrally has an angle portion 42 screwed to the frame 15 and a detection portion 43 extending on the inner peripheral side along the indoor side wall of the inner peripheral side member 23. doing. The finding portion 43 is formed in a hollow shape. At the inner circumferential end of the finding portion 43, there is provided an indoor guide groove 34b opened at the outdoor side. The indoor guide groove 34b is provided to face the outdoor guide groove 34a formed in the inner peripheral side member 23, and as shown in FIG. 3, the indoor guide groove 34b is sandwiched between the outdoor guide groove 34a and the indoor guide groove 34b. A slider 44 connected with an arm 8 for restricting the inward tilt angle of the inner scissor 2 is slidably guided in the vertical direction. Further, as shown in FIG. 2, the inner peripheral end 45 of the indoor guide groove 34 b is a sliding portion of the claw 46 of the latch 7 attached to the upper portion of the inner shutter 2. As shown in FIG. 9, the inner circumferential side member 23 is cut under the balancer, while the angle member 39 extends to the lower surface of the upper frame 9. The inner circumferential side member 23 of the vertical frame 5 and the angle member 39 are removable.

このように、縦枠5を外周側部材22と内周側部材23とに分割して形成することで、内周側部材23の上部をフラットに切断するだけで、縦枠5の上部内周側面にバランサー3の取付けスペース27を容易に確保することができる。内周側部材23の室内側に外周側に凹んだ凹部28を形成し、凹部28の底部側から入口側にかけてワイヤー挿通部29、内障子2の下部(ロッド棒31)のガイド部(内向き突部30a,30b)、アームスライダー44のガイド部(ガイド溝34a,34b)、内障子2の上部(ラッチ7)のガイド部(アングル材39の内周側端部45)を順に形成することで、縦枠5の見付寸法をコンパクトに抑えつつ高機能のガイド部を構成できる。アングル材39を内周側部材23と別体で形成し、アングル材39を上枠までのばし、アングル材39の内周側端部45を内障子2上部(ラッチ7)のガイド部としたことで、アングル材39でバランサー3を隠蔽することができ、また、内障子2上部をバランサー3の下端を超えて上までスムーズにガイドできる。内周側部材23とアングル材39を樹脂製とし、さらにこれらに中空部32a,32b,32c,32dを設けることで、高い断熱性能が得られる。さらに、内周側部材23の凹部28に樹脂製の目板35を取付けてワイヤー挿通部29を隠したことで、断熱性能がさらに向上すると共に、意匠性が向上する。目板35、内周側部材23、アングル材39は、取外し可能なので、メンテナンス性が良い。   As described above, the vertical frame 5 is divided into the outer peripheral side member 22 and the inner peripheral side member 23 so that the upper inner periphery of the vertical frame 5 can be obtained simply by cutting the upper portion of the inner peripheral side member 23 into a flat shape. The mounting space 27 of the balancer 3 can be easily secured on the side surface. A recessed portion 28 recessed toward the outer peripheral side is formed on the indoor side of the inner peripheral side member 23, and the wire inserting portion 29 from the bottom side to the inlet side of the recessed portion 28 Forming the projections 30a, 30b), the guide portions (guide grooves 34a, 34b) of the arm slider 44, and the guide portions (inner peripheral end 45 of the angle member 39) of the upper portion (latch 7) of the inner shutter 2 in this order Thus, the high-performance guide portion can be configured while suppressing the size of the vertical frame 5 in a compact size. The angle member 39 is formed separately from the inner peripheral side member 23, the angle member 39 is extended to the upper frame, and the inner peripheral end 45 of the angle member 39 is used as a guide portion of the upper inner scissor 2 (latch 7). Thus, the balancer 3 can be concealed by the angle member 39, and the upper part of the inner scissor 2 can be smoothly guided to the upper side beyond the lower end of the balancer 3. By making the inner peripheral side member 23 and the angle member 39 made of resin and further providing the hollow portions 32a, 32b, 32c, 32d in these, high heat insulation performance can be obtained. Furthermore, by attaching the resin-made eye plate 35 to the recessed part 28 of the inner peripheral side member 23 and concealing the wire insertion part 29, while a heat insulation performance is further improved, a designability improves. Since the eye plate 35, the inner peripheral side member 23, and the angle member 39 are removable, they have good maintainability.

バランサー3は、図7,9に示すように、縦枠5の上部内周側面に取付けてあり、より詳細には、縦枠5の内周側部材23の上端と上枠9との間で、縦枠5の外周側部材22内の室外側の見付壁24と室内側の見付部43の間のスペース27に配置し、外周側部材22の内周側面に取付けてある。バランサー3は、図8,9に示すように、縦枠5の室内側の見付部43の内周側縁より外周側に略収まっており、すなわち縦枠5の室内側の見付寸法内に略収まっており、室内側から見るとバランサー3はアングル材39の見付部43に隠れて見えない。厳密に言えば、バランサー3の上部に設けられる主軸56の先端部やラチェット58及びクリック59等の部品がアングル材39の見付部43より内周側に少し出っ張るが、この部分は後述するバランサーカバー61のストッパー69にてカバーされて隠れる。またバランサー3は、縦枠5の室外側の見付寸法(室外側の見付壁24の見付寸法)内には、全体が完全に収まっている。またバランサー3は、図9に示すように、上枠9の内周側部材12の端部に形成した切り欠き21より、上枠9内に15mm程度のみ込ませてあり、のみ込ませた分だけバランサー3の下端位置が高くなっている。   As shown in FIGS. 7 and 9, the balancer 3 is attached to the upper inner peripheral side surface of the vertical frame 5, and more specifically, between the upper end of the inner peripheral side member 23 of the vertical frame 5 and the upper frame 9. The space 27 is disposed in the space 27 between the outdoor-side viewing wall 24 and the indoor-side viewing portion 43 in the outer peripheral side member 22 of the vertical frame 5 and is attached to the inner peripheral side surface of the outer peripheral side member 22. As shown in FIGS. 8 and 9, balancer 3 is substantially accommodated on the outer peripheral side from the inner peripheral side edge of find portion 43 on the indoor side of vertical frame 5, that is, within the looking dimension of indoor side of vertical frame 5. The balancer 3 can not be seen behind the finder 43 of the angle member 39 when viewed from the indoor side. Strictly speaking, the tip of the main shaft 56 provided on the upper part of the balancer 3 and parts such as the ratchet 58 and the click 59 are slightly protruded to the inner peripheral side from the finding part 43 of the angle member 39 It is covered and hidden by the stopper 69 of the cover 61. The whole of the balancer 3 is completely contained within the outside-side looking dimension of the vertical frame 5 (the looking-down dimension of the outside-side looking wall 24). Further, as shown in FIG. 9, the balancer 3 is only about 15 mm embedded in the upper frame 9 from the notch 21 formed at the end of the inner peripheral side member 12 of the upper frame 9, and the balancer The lower end position of 3 is high.

バランサー3は、図7,10,11に示すように、外周側に合成樹脂で形成されたベース部材47が配置され、ベース部材47にゼンマイバネ48を収容した香箱49とワイヤー6を巻き取るドラム50とを、それぞれの軸を左右方向に向けて上下に並べて軸支し、香箱49とドラム50を被うようにベース部材47に内周側から金属製のプレート51を取付けている。香箱49とドラム50の外径は、略同じになっている。香箱49の外周側には香箱歯車52が、ドラム50の外周側にはドラム歯車53がそれぞれ設けてあり、香箱歯車52とドラム歯車53に噛み合うように連係歯車54がベース部材47に取付けてあり、ゼンマイバネ48に蓄勢された回転トルクが連係歯車54を介してドラム50に伝達されている。このように香箱歯車52とドラム歯車53の間に連係歯車54を噛ませることで、香箱歯車52とドラム歯車53を香箱49とドラム50の外周からはみ出さないように小さくでき、ベース部材47の見込み方向寸法を香箱49とドラム50の外径ぎりぎりまで小さくできる。逆に言えば、縦枠5の見込み寸法に対して香箱49とドラム50の径をできるだけ大きくすることができ、これにより大荷重にも対応可能なバランサー3となっている。3つの歯車52,53,54は、鉛直線上に一直線に配置され、且つ3つの歯車52,53,54のピッチ円直径を同じにしてある。これにより、各歯車52,53,54が負担するトルクを均一化でき、スムーズな回転を確保すると共に、歯車52,53,54の耐久性を向上できる。
ドラム50は、内周側に向かうにつれて径が小さくなっており、径を小さくすることでできたスペース95(図12参照)を利用して、後述する内障子2のラッチ7の爪46が通過できる溝部55を設けている。歯車52,53,54とドラム50は、樹脂製である。

A coupling gear 54 is attached to the base member 47 so as to mesh with the barrel gear 52 and the drum gear 53. The rotational torque stored in the spring 48 is transmitted to the drum 50 via the connecting gear 54. As described above, by engaging the coupling gear 54 between the barrel gear 52 and the drum gear 53, the barrel gear 52 and the drum gear 53 can be made smaller so as not to protrude from the outer periphery of the barrel 49 and the drum 50. The expected direction dimension can be reduced to just the outside diameter of the barrel 49 and the drum 50. Conversely speaking, the diameter of the barrel 49 and the drum 50 can be made as large as possible with respect to the expected dimensions of the vertical frame 5, and thereby, the balancer 3 can cope with a large load. The three gears 52, 53, 54 are arranged in a straight line on the vertical line, and the pitch circle diameters of the three gears 52, 53, 54 are the same. As a result, the torques that the gears 52, 53, 54 bear can be made uniform, smooth rotation can be ensured, and the durability of the gears 52, 53, 54 can be improved.
The diameter of the drum 50 decreases toward the inner circumferential side, and the claws 46 of the latch 7 of the inner scissor 2 described later pass through the space 95 (see FIG. 12) formed by reducing the diameter. The groove 55 is provided. The gears 52, 53, 54 and the drum 50 are made of resin.
In the base member 47, the shaft 90 of the drum 50 and the shaft 91 of the connecting gear 54 are integrally formed on the bottom plate portion 89. Further, as shown in FIG. 11, the base member 47 is provided with a side wall 93 so as to cover the periphery of the case 92 of the metal barrel 49.

A claw piece 72a to be engaged with the vertical hook 71 of the outer shutter 4 is provided on the outdoor side at the top, and a claw piece 72b is engaged with the angle member 39 of the vertical frame 5 at the indoor side. The balancer cover 61, as shown in FIG. 14, is inserted into and locked to the inner peripheral side member 23 of the vertical frame 5 with the locking pieces 70a, 70b and 70c formed at the lower end in an oblique state. When the outer peripheral side is pushed and raised vertically, the upper claws 72a and 72b are held and held between the vertical weir 71 and the vertical frame 5 of the outer shell 4 as shown in FIG. 8A. The upper end of the balancer cover 61 is in contact with the lower surface of the inner peripheral side member 12 of the upper frame 9 as shown in FIG. 9C. At a lower end portion of the balancer cover 61, as shown in FIGS. 7 and 8, there is provided an eye plate sagging preventing portion 73 which engages with the eye plate 35 of the vertical frame 5 to prevent the eye plate 35 from being lowered. The balancer cover 61 can be easily removed by inserting a tool such as a minus driver into a notch 74 (see FIG. 9C) formed in the upper indoor side surface of the stopper 69.

内障子2のラッチ7は、図15〜17に示すように、縦框75の上端部に固定されるベース部76と、ベース部76に内外周方向に摺動可能に保持されたラッチ本体77と、ラッチ本体77を外周側に付勢するバネ78と、ベース部76上面に設けた操作部材79とを有している。ラッチ本体77は、外周側面の下部室内側に爪46をベース部76から突出して有しており、爪46は縦枠5の凹部28の入口側に係合している。操作部材79はラッチ本体77と係合しており、操作部材77を内周側に動かすと、ラッチ本体77の爪46がベース部76に没入し、内障子2を室内側に倒せるようになる。
ラッチ本体77の爪46は、内障子2の上端から所定の寸法A(図15参照)だけ下がった位置に設けてあり、その寸法Aは、バランサーカバー61のストッパー69の下面と溝部55の上端との間の寸法B(図7参照)と略同じか、それ以上としてある。これにより内障子2をその上端がストッパー69に当接する限界まで上げたときでも、ラッチ本体77の爪46が溝部55の上端まで届かず、内障子2をストッパー69に当接する限界まで支障なく上げることができる。また、ラッチ5の爪46を室内寄りに配置したことで、内障子2を上げたときに爪46がバランサー3のドラム50と干渉するのを避けることができる。
As shown in FIGS. 15-17, the latch 7 of the inner scissor 2 includes a base 76 fixed to the upper end of the longitudinal rod 75 and a latch body 77 slidably held by the base 76 in the inner and outer peripheral directions. And a spring 78 for biasing the latch body 77 to the outer peripheral side, and an operation member 79 provided on the upper surface of the base portion 76. The latch main body 77 has a claw 46 projecting from the base portion 76 on the lower chamber side of the outer peripheral side, and the claw 46 is engaged with the inlet side of the concave portion 28 of the vertical frame 5. The operating member 79 is engaged with the latch main body 77, and when the operating member 77 is moved to the inner peripheral side, the claws 46 of the latch main body 77 retract into the base portion 76, and the inner shutter 2 can be turned indoors. .
The claw 46 of the latch main body 77 is provided at a position lowered by a predetermined dimension A (see FIG. 15) from the upper end of the inner shell 2, and the dimension A is the lower surface of the stopper 69 of the balancer cover 61 and the upper end of the groove 55 And approximately the same as or larger than the dimension B (see FIG. 7). Thus, even when the inner scissor 2 is raised to the limit where the upper end thereof abuts against the stopper 69, the claw 46 of the latch main body 77 does not reach the upper end of the groove 55 and raises the inner scissor 2 to the limit of abutting the stopper 69 be able to. Further, by arranging the claws 46 of the latch 5 closer to the room, it is possible to prevent the claws 46 from interfering with the drum 50 of the balancer 3 when the inner scissor 2 is raised.

内障子2の上框36は、図1に示すように、室外側に配置された金属製形材80と、室内側に配置された樹脂製形材81とを組み合わせて構成してあり、上框36の室内外方向の中央より室内側は樹脂製形材81の中空部82a,82b,82cで構成してある。
ラッチ本体77は、図16に示すように、爪46をベース部76に没入させたときに上框36内に挿入される後端部83を有しており、この後端部83は爪46よりも室外側に設けてあり、したがってラッチ本体77は平面視で略クランク状となっている。そして後端部83は、爪46をベース部76に没入したときには、樹脂製形材81の最も室外側の中空部82aよりも室外側に挿入される。そのため、ラッチ7を取付けるために樹脂製形材81の中空部82a,82b,82cを切欠く必要がないので、加工が容易であると共に、樹脂製形材81の中空部82a,82b,82cにより高い断熱性能が得られる。
なお、内障子2の上框36以外の框(下框84、縦框75)も、上框36と同様に金属製形材80と樹脂製形材81とを組み合わせて構成してある。外障子4の各框も、金属製形材80と樹脂製形材81とを組み合わせて構成してある。
As shown in FIG. 1, the upper collar 36 of the inner seal 2 is configured by combining a metal profile 80 disposed on the outdoor side and a resin profile 81 disposed on the indoor side. The indoor side from the center of the indoor / outdoor direction of the weir 36 is constituted by hollow portions 82a, 82b, 82c of the resin shaped material 81.
The latch body 77 has a rear end 83 which is inserted into the upper collar 36 when the claw 46 is inserted into the base 76 as shown in FIG. The latch main body 77 is substantially crank-shaped in plan view. When the claw 46 is inserted into the base portion 76, the rear end portion 83 is inserted outside the hollow portion 82a on the outermost side of the resin shaped member 81. Therefore, there is no need to cut out the hollow portions 82a, 82b and 82c of the resin shaped member 81 in order to attach the latch 7, so that processing is easy and by the hollow portions 82a, 82b and 82c of the resin shaped member 81. High thermal insulation performance is obtained.
In the same manner as the upper rod 36, the outer rods 36 (lower rod 84 and vertical rods 75) other than the upper rod 36 of the internal seal 2 are also configured by combining the metal shaped material 80 and the resin shaped material 81. Each collar of the outer shutter 4 is also configured by combining a metal profile 80 and a resin profile 81.

以上に述べたように本建具は、内障子2を吊るバランサー3を縦枠5の上部内周側面に取付けたことで、上枠9の見付寸法を小さくすることができ、バランサー3は内障子2を吊るワイヤー6を巻き取るドラム50を有し、内障子2は、上端がドラム50の下端より上にくる高さまでガイドされていることで、内障子2をその上端を少なくともドラム50の下端より高い位置まで摺動できる(実施形態のものは、さらに香箱49の下端より高い位置まで摺動できる)ため、開口面積を大きくできる。バランサー(バランサーカバー61)は、下端より上下方向の中間部にわたって内障子2のラッチ7の爪46が通過できる溝部55を有しているので、ラッチ7の爪46がバランサー3に衝突して内障子2の可動範囲が規制されることがない。さらにバランサー(バランサーカバー61)は、ドラム50より高い位置に内障子2のストッパー69を有するので、ストッパー69を別途設置する必要がないので、部品コストや組み立てコストを低減することができ、しかもバランサー3の大きさによらず広い開口面積を確保できる。   As described above, this fixture can reduce the size of the upper frame 9 by attaching the balancer 3 for suspending the inner scissor 2 to the upper inner peripheral side surface of the vertical frame 5, and the balancer 3 is The inner shutter 2 is guided to a height at which the upper end is above the lower end of the drum 50, so that the inner shutter 2 has at least the upper end of the drum 50. Since it can slide to a position higher than the lower end (in the embodiment, it can slide to a position higher than the lower end of the barrel 49), the opening area can be increased. Since the balancer (balancer cover 61) has a groove 55 through which the claw 46 of the latch 7 of the inner shutter 2 can pass over the middle portion in the vertical direction from the lower end, the claw 46 of the latch 7 collides with the balancer 3 The movable range of the shoji 2 is not restricted. Furthermore, since the balancer (balancer cover 61) has the stopper 69 of the inner shutter 2 at a position higher than the drum 50, there is no need to separately install the stopper 69, so parts cost and assembly cost can be reduced. A wide opening area can be secured regardless of the size of 3.

本建具は、バランサー3のベース部材47を樹脂製とし、樹脂製のベース部材47と金属製のプレート51とでドラム50と香箱49を保持しており、その樹脂製のベース部材47を縦枠5内周側面に当接させたことで、縦枠5からバランサー3に冷気が伝わるのを防止できるので、断熱性能が向上する。ベース部材47自体を樹脂製としたことで、バランサー3と縦枠5との間に樹脂製のスペーサー等の断熱材を介在させる必要がないので、部品点数を削減できる上、バランサー3の取付けが簡単になり、しかもバランサー3の厚みを薄くできる。また、ドラム50等の軸90等をベース部材47に一体成形できるので、これによってもバランサー3の厚みを薄くできる。またバランサー3は、ベース部材47やドラム50等の主要な部品が樹脂製であり、香箱49の金属製のケース92の周囲はベース部材76の側壁93で覆われているので、単に枠への取付面だけに樹脂製のスペーサー等を介在させて断熱した場合よりも断熱性が高い。さらに、バランサー3の金属製のプレート51の内観露出面を樹脂製のバランサーカバー61で被ってあることで、該プレート51から室内に冷気が放射されるのを抑えることができるので、断熱性能がさらに向上する。内周側に金属製のプレート51を配置したことで、必要な強度を担保することができ、またプレート51上にラチェット58やクリック59等の荷重のかかる部品を配置することができる。   In this fixture, the base member 47 of the balancer 3 is made of resin, and the drum 50 and the barrel 49 are held by the base member 47 made of resin and the plate 51 made of metal. Since the cold air can be prevented from being transmitted from the vertical frame 5 to the balancer 3 by being brought into contact with the inner circumferential side surface 5, the heat insulation performance is improved. Since the base member 47 itself is made of resin, there is no need to interpose a heat insulating material such as a resin spacer between the balancer 3 and the vertical frame 5, so that the number of parts can be reduced and the balancer 3 can be attached. This can be simplified and the thickness of the balancer 3 can be reduced. Further, since the shaft 90 and the like of the drum 50 and the like can be integrally formed on the base member 47, the thickness of the balancer 3 can be reduced also by this. In the balancer 3, the main parts such as the base member 47 and the drum 50 are made of resin, and the periphery of the metal case 92 of the barrel 49 is covered by the side wall 93 of the base member 76. Thermal insulation is higher than the case where heat insulation is performed by interposing a resin spacer or the like only on the mounting surface. Furthermore, by covering the exposed inner surface of the metal plate 51 of the balancer 3 with the resin balancer cover 61, it is possible to suppress the radiation of cold air from the plate 51 into the room, so the heat insulating performance is improved. Further improve. By arranging the metal plate 51 on the inner peripheral side, it is possible to secure necessary strength, and to place a load-appearing part such as the ratchet 58 or the click 59 on the plate 51.

本建具は、バランサー3が縦枠5の上部内周側面に取付けてあり、バランサー3は縦枠5の見付寸法内に収まっており、且つ上部を上枠9内にのみ込ませてあることで、開口面積を上下方向、左右方向共に大きくできる。本建具は、上枠9の下面にブラケット64を有し、バランサー3はブラケット64に引っ掛けるための引掛け部(係止片63)を有することで、バランサー3を上枠9にのみ込ませて取付けるのが容易である。バランサー3の引掛け部(係止片63)は、金属製のプレート51に設けてあることで、バランサー3にかかる荷重を上枠9に伝えられるので、バランサー3を1本のネジ67だけで安定して枠1に取付けできる。縦枠5が外周側部(外周側部材22)と内周側部(内周側部材23)とからなり、内周側部(内周側部材23)はバランサー3より下方に設けてあり、内障子2のガイド部(凹部28)と内障子2を吊る吊部材(ワイヤー6)の挿通部29を有することで、バランサー3を取付けるために縦枠5に複雑な加工をする必要がなく、製造コストを低減できる。さらに、内周側部(内周側部材23)は樹脂製であり、吊部材の挿通部29が樹脂製の目板35で塞いであることで、断熱性及び意匠性が向上する。   In this construction, the balancer 3 is attached to the upper inner peripheral side surface of the vertical frame 5, and the balancer 3 is accommodated within the found dimensions of the vertical frame 5, and the upper portion is embedded in the upper frame 9. The opening area can be increased in both the vertical and horizontal directions. This fixture has a bracket 64 on the lower surface of the upper frame 9, and the balancer 3 has a hooking portion (locking piece 63) for hooking on the bracket 64, thereby attaching the balancer 3 only to the upper frame 9. It is easy. The hooking portion (locking piece 63) of the balancer 3 is provided on the metal plate 51, so that the load applied to the balancer 3 can be transmitted to the upper frame 9. It can be attached to the frame 1 stably. The vertical frame 5 is composed of an outer peripheral side portion (an outer peripheral side member 22) and an inner peripheral side portion (an inner peripheral side member 23), and an inner peripheral side portion (an inner peripheral side member 23) is provided below the balancer 3. By having the guide part (concave part 28) of the inner gutter 2 and the insertion part 29 of the hanging member (wire 6) for suspending the inner gutter 2, there is no need to make complicated processing on the vertical frame 5 in order to attach the balancer 3. The manufacturing cost can be reduced. Further, the inner peripheral side portion (inner peripheral side member 23) is made of resin, and the heat insulating property and the designability are improved by the insertion portion 29 of the hanging member being closed by the resin made plate 35.

本建具は、バランサー3のドラム50の軸90が左右方向を向いているので、バランサー3を縦枠5内に収めることができ、またバランサー3を上枠9内に収める必要がないため上枠9の見付寸法を小さくできることから、開口面積(上下方向)を大きくできる。縦枠5の内周側部材23の上端と上枠9間にバランサーカバー61が取付けてあるので、意匠性がよい。バランサーカバー61は、室内側から簡単に取り外すことができ、バランサーカバー61を取外すことでバランサー3の調整やメンテナンスが容易に行える。   In this construction, since the shaft 90 of the drum 50 of the balancer 3 faces in the left-right direction, the balancer 3 can be accommodated in the vertical frame 5, and the balancer 3 does not have to be accommodated in the upper frame 9. Since the find size of 9 can be reduced, the opening area (vertical direction) can be increased. Since the balancer cover 61 is attached between the upper end of the inner peripheral side member 23 of the vertical frame 5 and the upper frame 9, the design is good. The balancer cover 61 can be easily removed from the indoor side, and by removing the balancer cover 61, adjustment and maintenance of the balancer 3 can be easily performed.

図19は、上枠9に取付けられるブラケット64とバランサーカバー61の他の実施形態を示している。ブラケット64は、左右勝手違いのものとしてあり、バランサー3を引っ掛けるための爪片66とは別に垂下片85を有し、バランサーカバー61の上部のストッパー69を垂下片85に内周側から係合するとともに、内障子2の全開時にストッパー69が受ける上向きの衝撃を、垂下片85の下端で受け止め可能としている。
本実施形態によれば、バランサーカバー61を取り付ける際、傾斜させた状態でバランサーカバー61の下端を縦枠5の内周側部材23の上端に載置させた後、バランサーカバー61を起立させてバランサーカバー61の上端近傍をブラケット64の垂下片85に係合させるだけでバランサーカバー61の装着ができ、バランサーカバー61の取り付けを容易に行うことができる。
そしてブラケット64の垂下片85を利用して、内障子2開放時にストッパー69が受けた衝撃を垂下片85に受けさせるとともに、垂下片85から上枠9で確実に受け止めることができる。また、バランサーカバー61の下端に設けた突起部86を、縦枠5の載置部に嵌合させていることから、バランサーカバー61は上下でそれぞれ係合状態となり、安定した固定が可能となる。
FIG. 19 shows another embodiment of the bracket 64 and the balancer cover 61 attached to the upper frame 9. The bracket 64 has left and right handedness and has a hanging piece 85 separately from the claw piece 66 for hooking the balancer 3 and engages the stopper 69 on the upper part of the balancer cover 61 with the hanging piece 85 from the inner peripheral side At the same time, the lower end of the hanging piece 85 can receive an upward impact which the stopper 69 receives when the inner shutter 2 is fully opened.
According to the present embodiment, when attaching the balancer cover 61, after the lower end of the balancer cover 61 is placed on the upper end of the inner peripheral side member 23 of the vertical frame 5 in an inclined state, the balancer cover 61 is erected. The balancer cover 61 can be mounted simply by engaging the vicinity of the upper end of the balancer cover 61 with the hanging piece 85 of the bracket 64, and the balancer cover 61 can be easily attached.
The hanging piece 85 of the bracket 64 can be used to make the hanging piece 85 receive the impact received by the stopper 69 when the inner shell 2 is opened, and the upper frame 9 can reliably receive the impact from the hanging piece 85. In addition, since the projection 86 provided at the lower end of the balancer cover 61 is fitted to the mounting portion of the vertical frame 5, the balancer cover 61 is engaged at the upper and lower sides, and stable fixing is possible. .

本発明は以上に述べた実施形態に限定されない。枠や障子の形態は、適宜変更することができる。バランサーの樹脂製のベース部材、金属製のプレートの形状は、適宜変更することができる。またバランサーは、香箱とドラムを同一軸上に配置したものであってもよい。バランサーは上枠にのみ込ませてなくてもよい。本発明は、上げ下げ窓の他、上げ下げ窓付きの戸等に適用することもできる。   The present invention is not limited to the embodiments described above. The form of the frame and the shoji can be changed as appropriate. The shape of the resin base member of the balancer and the shape of the metal plate can be changed as appropriate. Also, the balancer may be one in which the barrel and the drum are arranged on the same axis. The balancer does not have to be embedded in the upper frame.
