Description

本発明は、建具に関し、特に、建具の断熱性能に関する。   The present invention relates to joinery, and more particularly, to heat insulation performance of joinery.

一般家庭において、室内から室外に逃げる熱の半分以上は窓から逃げるといわれる。ガラス自体の改良だけでなく、ガラスの複層化により、ガラスの断熱性能は大きく向上しつつある。このため、ガラスよりもむしろサッシ（枠体）の方が熱を逃がしやすい。   In ordinary households, it is said that more than half of the heat escaping from room to room escapes from the window. Not only the improvement of the glass itself, but also the heat insulation performance of the glass has been greatly improved by the multilayering of the glass. For this reason, a sash (frame body) rather than glass tends to release heat.

樹脂のサッシは、アルミニウムのサッシよりもコストが高くなるものの、断熱性能や質感にすぐれるという長所がある。樹脂のサッシ枠は、特に、北海道などの寒冷地で好まれている。   Resin sashes are more expensive than aluminum sashes, but have the advantage of superior thermal insulation performance and texture. Resin sash frames are particularly preferred in cold regions such as Hokkaido.

特開２００５−２７３２３１号公報JP-A-2005-273231

サッシを樹脂で形成すれば断熱性能は大きく向上するが、更に、断熱性能を向上させるためにさまざまな研究開発が行われている。たとえば、樹脂サッシの内部を複数の空間に分割したり、それらの空間にウレタンなどの断熱材を挿入するといった方法も提案されているが、このような方法はサッシの形状を複雑化するため製造が難しい。   If the sash is made of resin, the heat insulation performance will be greatly improved, but various research and development have been conducted to further improve the heat insulation performance. For example, methods such as dividing the interior of a resin sash into a plurality of spaces and inserting a heat insulating material such as urethane into those spaces have been proposed, but such methods are manufactured to complicate the shape of the sash. Is difficult.

本発明は、上記課題に鑑みてなされたものであり、その主たる目的は、簡易な構成にて、かつ、効果的にサッシの断熱性能を向上させるための技術、を提供することにある。   This invention is made | formed in view of the said subject, The main objective is to provide the technique for improving the heat insulation performance of a sash effectively with a simple structure.

本発明のある態様の建具（サッシ窓）は、内側レールにおいて走行可能となるように内障子を収め、外側レールにおいて走行可能となるように外障子を収める枠体と、枠体の縦枠に沿って追加的に取り付けられ、縦枠の断熱性能を強化する第１の断熱強化部材と、を備える。   A joinery (sash window) according to an aspect of the present invention includes a frame that houses an inner shoji so that it can run on the inner rail, and a vertical frame that holds the outer shoji so that it can run on the outer rail. And a first heat insulation reinforcing member that is additionally attached along the wall and reinforces the heat insulation performance of the vertical frame.

この態様によると、枠体をシンプルな構造としつつも、断熱効果を高めやすい縦枠に第１の断熱強化部材を後から追加することで、製造コストを抑制しつつ断熱性能を高めやすくなる。   According to this aspect, it becomes easy to improve heat insulation performance, suppressing manufacturing cost by adding a 1st heat insulation reinforcement | strengthening member later to the vertical frame which is easy to raise a heat insulation effect, making a frame a simple structure.

第１の断熱強化部材は、第１の断熱強化部材の内壁と縦枠の表面により筒状空間を形成してもよい。
縦枠に沿って延伸する第１の断熱強化部材そのものが筒状空間（断熱層）を備えてもよいが、筒の３面を第１の断熱強化部材の内壁により形成し、残る１面を縦枠の表面で形成することにより、第１の断熱強化部材をよりシンプルな構造にしやすくなる。 The first heat insulating reinforcing member may form a cylindrical space by the inner wall of the first heat insulating reinforcing member and the surface of the vertical frame.
The first heat-insulating / reinforcing member itself extending along the vertical frame may be provided with a cylindrical space (heat-insulating layer), but the three surfaces of the tube are formed by the inner wall of the first heat-insulating / reinforcing member, and the remaining one surface is formed. By forming on the surface of the vertical frame, the first heat insulating reinforcing member can be easily made into a simpler structure.

第１の断熱強化部材は、縦枠との間に複数の筒状空間を形成してもよい。
第１の断熱強化部材の内部を複数の筒状空間に区切ることで、筒状空間における内部空気の対流を抑制し、ひいては、断熱性能をいっそう高めやすくなる。 A 1st heat insulation reinforcement | strengthening member may form a some cylindrical space between vertical frames.
By dividing the interior of the first heat insulation reinforcing member into a plurality of cylindrical spaces, convection of the internal air in the cylindrical spaces is suppressed, and as a result, the thermal insulation performance can be further enhanced.

枠体の下枠に沿って追加的に取り付けられ、下枠の断熱性能を強化する第２の断熱強化部材、を更に備えてもよい。
縦枠だけでなく下枠も熱の通り道になりやすいため、下枠を第２の断熱強化部材で断熱補強することにより、枠体全体としての断熱性能をいっそう高めやすくなる。 You may further provide the 2nd heat insulation reinforcement | strengthening member attached along the lower frame of a frame, and strengthening the heat insulation performance of a lower frame.
Since not only the vertical frame but also the lower frame is likely to be a path for heat, the thermal insulation performance of the entire frame can be further enhanced by reinforcing the lower frame with the second thermal insulation reinforcing member.

縦枠の下部に内障子を停止させるためのストッパー、を更に備えてもよい。このストッパーは、第１の断熱強化部材を差し込むための切欠部を有してもよい。
第１の断熱強化部材をストッパーの切欠部に差し込むことで、より長い第１の断熱強化部材を利用でき、また、第１の断熱強化部材の下端部を下枠の上面だけでなくストッパーでも覆うことができるので、第１の断熱強化部材により形成される筒状空間の密封性を高めやすくなる。 You may further provide the stopper for stopping the inner shoji in the lower part of a vertical frame. This stopper may have a notch for inserting the first heat insulation reinforcing member.
By inserting the first heat insulation reinforcing member into the notch portion of the stopper, a longer first heat insulation reinforcing member can be used, and the lower end portion of the first heat insulation reinforcing member is covered not only by the upper surface of the lower frame but also by the stopper. Therefore, it becomes easy to improve the sealing performance of the cylindrical space formed by the first heat insulation reinforcing member.

本発明によれば、簡易構成にて、サッシの断熱性能を高めやすくなる。   According to this invention, it becomes easy to improve the heat insulation performance of a sash with a simple structure.

図１は、障子１１０の形成方法を説明するための模式図である。
障子１１０は、パネル１０２（ガラス）を樹脂製の框（かまち）１０１で囲ったものである。本実施形態におけるパネル１０２は、３層ガラスであり層間にはアルゴンガスやクリプトンガスなどの不活性ガスが封入されている。不活性ガスが輻射熱を遮断する効果によりパネル１０２の断熱性能を高めている。 FIG. 1 is a schematic diagram for explaining a method of forming the shoji 110.
The shoji 110 is obtained by surrounding a panel 102 (glass) with a resin stool 101. The panel 102 in this embodiment is a three-layer glass, and an inert gas such as argon gas or krypton gas is sealed between the layers. The heat insulating performance of the panel 102 is enhanced by the effect of the inert gas blocking radiant heat.

框１０１の形成に際しては、まず、樹脂の押し出し成型品である框部材から２つの横框１０６ａ，１０６ｂと２つの縦框１０８ａ，１０８ｂを斜め４５度にて切り出す。そして、横框１０６ａ，１０６ｂ，縦框１０８ａ，１０８ｂの継ぎ目を溶かして接着することにより額縁形状の框１０１を作る。すなわち、横框１０６ａ，１０６ｂ，縦框１０８ａ，１０８ｂの内部構造は同一であり、横框１０６と縦框１０８は長さだけが異なる。次に、框１０１（横框１０６ａ，１０６ｂ，縦框１０８ａ，１０８ｂ）にパネル１０２を嵌め、図示しない結合部材等によりパネル１０２を框１０１に固定する。こうして、障子１１０が形成される。   When forming the ridge 101, first, the two horizontal ridges 106a and 106b and the two vertical ridges 108a and 108b are cut at an angle of 45 degrees from the ridge member that is an extruded product of resin. Then, the frame-shaped ridge 101 is made by melting and bonding the joints of the horizontal ridges 106a and 106b and the vertical ridges 108a and 108b. That is, the internal structures of the reeds 106a and 106b and the reeds 108a and 108b are the same, and the reed 106 and the reeds 108 differ only in length. Next, the panel 102 is fitted to the ridge 101 (the horizontal ridges 106a and 106b, the vertical ridges 108a and 108b), and the panel 102 is fixed to the ridge 101 with a coupling member or the like (not shown). Thus, the shoji 110 is formed.

図２は、サッシ窓１００の形成方法を説明するための模式図である。
サッシ窓１００（建具）の枠体１１２も樹脂成型品である。框１０１と同様、樹脂の押し出し成型品である枠部材から左枠１１４、右枠１１８（合わせて、あるいは、特に特定しないときには「縦枠」ともよぶ）と上枠１１６、下枠１２０（合わせて、あるいは、特に特定しないときには「横枠」ともよぶ）を斜め４５度にて切り出す。縦枠と横枠のそれぞれの継ぎ目を溶かして接着することにより額縁形状の枠体１１２が形成される。枠体１１２においても、左枠１１４、右枠１１８、上枠１１６、下枠１２０の内部構造は同一であり、縦枠と横枠は長さだけが異なる。 FIG. 2 is a schematic diagram for explaining a method of forming the sash window 100.
The frame body 112 of the sash window 100 (joint) is also a resin molded product. As with the bag 101, the left frame 114 and the right frame 118 (also referred to as “vertical frame” unless otherwise specified), the upper frame 116, and the lower frame 120 (also combined) Or, if not specified, it is also called “horizontal frame”) at an angle of 45 degrees. The frame-shaped frame body 112 is formed by melting and bonding the joints of the vertical and horizontal frames. Also in the frame body 112, the left frame 114, the right frame 118, the upper frame 116, and the lower frame 120 have the same internal structure, and the vertical frame and the horizontal frame differ only in length.

ここで、図１に関連して説明した障子１１０を枠体１１２に嵌める。具体的には、室外側の障子１１０（以下、「外障子１２４」とよぶ）と室内側の障子１１０（以下、「内障子１２６」とよぶ）を上枠１１６側に嵌めて、下枠１２０のレールに障子１１０の車輪を載せることにより、引き違い窓としてのサッシ窓１００が形成される。   Here, the shoji 110 described with reference to FIG. Specifically, the outdoor shoji 110 (hereinafter referred to as “external shovel 124”) and the indoor shoji 110 (hereinafter referred to as “internal shoji 126”) are fitted to the upper frame 116 side, and the lower frame 120 is fitted. The sash window 100 as a sliding window is formed by placing the wheels of the shoji 110 on the rail.

図３は、サッシ窓１００の中央部における側断面図である。図４は、サッシ窓１００の中央部における上断面図である。
サッシ窓１００の本体は、室外側に半分だけ突き出した状態で壁１２８に固定される（半外付け窓）。サッシ窓１００の枠体１１２は、ネジにより壁１２８に固定される。半外付け窓は、サッシ窓１００の室内側にカーテンを設置する空間を確保できるので、室内をすっきりさせることができる。また、サッシ窓１００を壁１２８に取り付ける作業が比較的容易になるというメリットもある。 FIG. 3 is a side sectional view of the central portion of the sash window 100. FIG. 4 is an upper cross-sectional view at the center of the sash window 100.
The main body of the sash window 100 is fixed to the wall 128 in a state in which only half of the sash window 100 protrudes to the outdoor side (half-external window). The frame body 112 of the sash window 100 is fixed to the wall 128 with screws. The semi-external window can secure a space for installing the curtain on the indoor side of the sash window 100, so that the room can be cleaned. There is also an advantage that the operation of attaching the sash window 100 to the wall 128 becomes relatively easy.

外障子１２４と内障子１２６は、いずれも３層ガラスとして形成されるパネル１０２を框１０１で囲むことにより形成される。図３に示すように障子１１０（外障子１２４および内障子１２６）の横框１０６ｂ（下側）には車輪１３０が取り付けられる。内障子１２６の車輪１３０は、下枠１２０の室内側に形成される内側レール１３２を走行する。外障子１２４の車輪１３０は、下枠１２０の室外側に形成される外側レール１３４を走行する。   Both the external shoji 124 and the internal shoji 126 are formed by surrounding the panel 102 formed of three-layer glass with a ridge 101. As shown in FIG. 3, wheels 130 are attached to the recumbency 106b (lower side) of the shoji 110 (the outer shoji 124 and the inner shoji 126). The wheel 130 of the inner impeller 126 travels on the inner rail 132 formed on the indoor side of the lower frame 120. The wheel 130 of the outer panel 124 runs on an outer rail 134 formed on the outdoor side of the lower frame 120.

なお、左枠１１４、上枠１１６、右枠１１８、下枠１２０は、同一の枠部材から形成されるため、下枠１２０だけでなく、左枠１１４、上枠１１６および右枠１１８にも内側レール１３２と外側レール１３４と同様の構造が形成されているが、レールとして機能するのは下枠１２０だけである。框１０１のうち、車輪１３０が取り付けられるのも横框１０６ｂだけである。   Since the left frame 114, the upper frame 116, the right frame 118, and the lower frame 120 are formed from the same frame member, not only the lower frame 120 but also the left frame 114, the upper frame 116, and the right frame 118 are inside. A structure similar to that of the rail 132 and the outer rail 134 is formed, but only the lower frame 120 functions as a rail. Of the rod 101, the wheel 130 is attached only to the horizontal rod 106b.

左枠１１４の下方においては、内側レール１３２の一部を覆うようにストッパー１３６が設置される（図４）。ストッパー１３６は、内障子１２６が左枠１１４に接触・衝突するのを抑止する。   A stopper 136 is installed below the left frame 114 so as to cover a part of the inner rail 132 (FIG. 4). The stopper 136 prevents the inner impediment 126 from contacting and colliding with the left frame 114.

縦框１０８には、ｙ軸方向（縦方向）に沿って延伸する金属製のパネル芯材１３８が挿入される（図４）。パネル芯材１３８は、樹脂製の縦框１０８が熱などのストレスにより変形するのを抑止するための骨組みとして機能する。   A metal panel core 138 extending along the y-axis direction (longitudinal direction) is inserted into the vertical rod 108 (FIG. 4). The panel core material 138 functions as a framework for preventing the resin vertical rod 108 from being deformed by stress such as heat.

図４に示すように、サッシ窓１００の閉鎖時においては、外障子１２４は左枠１１４側に位置し、内障子１２６は右枠１１８側に位置する。なお、外障子１２４の外側には更に網戸１４０が設置されてもよい。   As shown in FIG. 4, when the sash window 100 is closed, the outer panel 124 is positioned on the left frame 114 side, and the inner panel 126 is positioned on the right frame 118 side. In addition, a screen door 140 may be further installed outside the shoji 124.

下枠１２０には、ｘ軸方向（横方向）に沿って延伸する金属製の下枠芯材１４２が挿入される（図３）。下枠芯材１４２は、下枠１２０において内側レール１３２と外側レール１３４の間の最下層空間に挿入され、外障子１２４と内障子１２６の重量を支える骨組みとして機能する。   A metal lower frame core material 142 extending along the x-axis direction (lateral direction) is inserted into the lower frame 120 (FIG. 3). The lower frame core member 142 is inserted into the lowermost layer space between the inner rail 132 and the outer rail 134 in the lower frame 120 and functions as a framework that supports the weight of the outer panel 124 and the inner panel 126.

サッシ窓１００の断熱性を特に高めたいのは窓を閉鎖したときである（図４に示す状態）。図４を参照すると、右枠１１８側においては、内障子１２６によってほぼ熱の流れを遮断できるが、左枠１１４には横経路Ａとして示す熱の抜け道がある。すなわち、右枠１１８側から抜けようとする熱は断熱性能が高い内障子１２６を通り抜ける必要があるが、左枠１１４側から抜けようとする熱は、外障子１２４や内障子１２６を通り抜けなくても左枠１１４だけを通り抜ければよい。そこで、本実施形態においては、左枠１１４の延伸方向（ｙ方向）に沿って延伸する縦枠カバー部材１４４（第１の断熱強化部材）を追加することにより、横経路Ａにおける熱の通過を抑制し、左枠１１４の断熱性能を強化している。   The heat insulating property of the sash window 100 is particularly desired to be enhanced when the window is closed (the state shown in FIG. 4). Referring to FIG. 4, on the right frame 118 side, the heat flow can be substantially blocked by the inner impeller 126, but the left frame 114 has a heat escape path indicated as a lateral path A. In other words, the heat that tries to escape from the right frame 118 side needs to pass through the inner limb 126 having high heat insulation performance, but the heat that tries to escape from the left frame 114 side does not pass through the outer obstacle 124 and the inner limb 126. Need only pass through the left frame 114. Therefore, in the present embodiment, by adding a vertical frame cover member 144 (first heat insulation reinforcing member) that extends along the extending direction (y direction) of the left frame 114, the passage of heat in the lateral path A is prevented. It suppresses and the heat insulation performance of the left frame 114 is strengthened.

同様に、図３を参照すると、下枠１２０にも下経路Ｂとして示される熱の抜け道が開いている。そこで、下枠１２０の延伸方向に沿って延伸する下枠カバー部材１４６（第２の断熱強化部材）を更に追加し、下経路Ｂにおける熱の通過を抑制し、下枠１２０の断熱性能も強化している。   Similarly, referring to FIG. 3, the lower frame 120 also has a passage for heat shown as the lower path B. Therefore, a lower frame cover member 146 (second heat insulating reinforcing member) extending along the extending direction of the lower frame 120 is further added to suppress the passage of heat in the lower path B, and the heat insulating performance of the lower frame 120 is also enhanced. doing.

縦枠カバー部材１４４は、左枠１１４の延伸方向の全域にわたって取り付けられることが好ましいが、少なくとも縦框１０８の長さと同程度以上の長さを有することが好ましい。同様に、下枠カバー部材１４６は、下枠１２０の延伸方向の全域にわたって取り付けられることが好ましいが、少なくとも横框１０６の長さと同程度以上の長さを有することが好ましい。   The vertical frame cover member 144 is preferably attached over the entire region of the left frame 114 in the extending direction, but preferably has a length that is at least as long as the vertical rod 108. Similarly, the lower frame cover member 146 is preferably attached over the entire region of the lower frame 120 in the extending direction, but preferably has a length that is at least equal to or longer than the length of the horizontal rib 106.

本実施形態においては、下枠１２０と左枠１１４に断熱強化部材を取り付け、上枠１１６と右枠１１８には取り付けていない。上述の理由により右枠１１８に断熱強化部材を取り付けたときの断熱効果が、左枠１１４（窓閉鎖時における内障子１２６の反対側の縦枠）に取り付けた場合に比べて低いためであるが、必要であれば右枠１１８にも取り付けてもよい。また、上枠１１６に断熱強化部材を取り付ける場合、障子１１０を枠体１１２に嵌め込むときの施工作業性が若干低下する可能性があるが、必要であれば上枠１１６にも断熱強化部材を取り付けてもよい。左枠１１４、上枠１１６、右枠１１８、下枠１２０のうち、左枠１１４に縦枠カバー部材１４４を取り付けたときの断熱効果が最も大きい。   In the present embodiment, the heat insulation reinforcing members are attached to the lower frame 120 and the left frame 114, and are not attached to the upper frame 116 and the right frame 118. This is because the heat insulation effect when the heat insulation reinforcing member is attached to the right frame 118 for the above-described reason is lower than the case where the heat insulation effect is attached to the left frame 114 (the vertical frame on the side opposite to the impeller 126 when the window is closed). If necessary, it may be attached to the right frame 118. Moreover, when attaching a heat insulation reinforcement | strengthening member to the upper frame 116, construction workability | operativity when inserting the shoji 110 in the frame 112 may fall a little, but if necessary, a heat insulation reinforcement | strengthening member is also attached to the upper frame 116, if necessary. It may be attached. Of the left frame 114, the upper frame 116, the right frame 118, and the lower frame 120, the thermal insulation effect is greatest when the vertical frame cover member 144 is attached to the left frame 114.

図５は、縦枠カバー部材１４４の周辺拡大図である。
左枠１１４は、下枠１２０と同構造であるため、内側レール１３２と外側レール１３４を有する。ただし、左枠１１４の内側レール１３２と外側レール１３４は実際にはレールとして機能しない。本実施形態においては、内側レール１３２と外側レール１３４の側面に小さなツメが形成されている。縦枠カバー部材１４４の側面にもツメが形成されており、縦枠カバー部材１４４のツメと左枠１１４のツメを噛み合わせることにより、ツールフリーにて縦枠カバー部材１４４を左枠１１４に取り付けることができる。このように、左枠１１４においては本来必要ない内側レール１３２と外側レール１３４の構造を再利用して縦枠カバー部材１４４を取り付けている。 FIG. 5 is an enlarged view of the periphery of the vertical frame cover member 144.
Since the left frame 114 has the same structure as the lower frame 120, the left frame 114 includes an inner rail 132 and an outer rail 134. However, the inner rail 132 and the outer rail 134 of the left frame 114 do not actually function as rails. In the present embodiment, small claws are formed on the side surfaces of the inner rail 132 and the outer rail 134. A tab is also formed on the side surface of the vertical frame cover member 144, and the vertical frame cover member 144 is attached to the left frame 114 in a tool-free manner by engaging the tabs of the vertical frame cover member 144 and the tabs of the left frame 114. be able to. As described above, the vertical frame cover member 144 is attached to the left frame 114 by reusing the structure of the inner rail 132 and the outer rail 134 that are not originally required.

なお、縦枠カバー部材１４４と左枠１１４の接続を更に強化するために、縦枠カバー部材１４４の一部を左枠１１４にネジで止めてもよい。   In order to further strengthen the connection between the vertical frame cover member 144 and the left frame 114, a part of the vertical frame cover member 144 may be fixed to the left frame 114 with a screw.

左枠１１４に縦枠カバー部材１４４を取り付けると、縦枠カバー部材１４４の表面と縦枠カバー部材１４４の内壁により２つの筒状空間１４８ａ，１４８ｂが形成される。筒状空間１４８は、ｙ方向（縦方向）に延伸する実質的な閉鎖空間である。この筒状空間１４８が断熱層として機能することにより、横経路Ａ（図４参照）における熱の流れを抑止する。筒状空間１４８が小さすぎると充分な断熱性能を期待できないし、筒状空間１４８が大きすぎると内部空気の対流現象により断熱性能が下がってくる。このため、左枠１１４や縦枠カバー部材１４４の大きさに応じて、縦枠カバー部材１４４の内部に形成される筒状空間１４８の数の最適数を決定すればよい。すなわち、筒状空間１４８は１つでもいいし、３つ以上でもよい。最適数は実験により決定すればよい。筒状空間１４８に、ウレタンなどの断熱材を挿入してもよい。本実施形態においては施工性やコストを考慮し、筒状空間１４８には何も挿入しないものとして説明する。   When the vertical frame cover member 144 is attached to the left frame 114, two cylindrical spaces 148a and 148b are formed by the surface of the vertical frame cover member 144 and the inner wall of the vertical frame cover member 144. The cylindrical space 148 is a substantially closed space extending in the y direction (longitudinal direction). The cylindrical space 148 functions as a heat insulating layer, thereby suppressing the heat flow in the lateral path A (see FIG. 4). If the cylindrical space 148 is too small, sufficient heat insulating performance cannot be expected, and if the cylindrical space 148 is too large, the heat insulating performance decreases due to the convection phenomenon of internal air. Therefore, the optimum number of the cylindrical spaces 148 formed inside the vertical frame cover member 144 may be determined according to the size of the left frame 114 and the vertical frame cover member 144. That is, the cylindrical space 148 may be one, or three or more. The optimum number may be determined by experiment. A heat insulating material such as urethane may be inserted into the cylindrical space 148. In the present embodiment, it is assumed that nothing is inserted into the cylindrical space 148 in consideration of workability and cost.

筒状空間１４８を形成する４側面のうちの１側面は左枠１１４の表面により形成され、残る３側面は縦枠カバー部材１４４の内壁面により形成される。縦枠カバー部材１４４で左枠１１４をカバーすることで筒状空間１４８を作る構造であるため、縦枠カバー部材１４４の構造をシンプルにできるというメリットがある。
変形例として、筒状空間１４８を有する縦枠カバー部材１４４、すなわち、筒状の縦枠カバー部材１４４を左枠１１４に取り付けてもよい。 One of the four side surfaces forming the cylindrical space 148 is formed by the surface of the left frame 114, and the remaining three side surfaces are formed by the inner wall surface of the vertical frame cover member 144. Since the cylindrical space 148 is formed by covering the left frame 114 with the vertical frame cover member 144, there is an advantage that the structure of the vertical frame cover member 144 can be simplified.
As a modification, the vertical frame cover member 144 having the cylindrical space 148, that is, the cylindrical vertical frame cover member 144 may be attached to the left frame 114.

図６は、縦枠カバー部材１４４の上面図および側面図である。図７は、下枠カバー部材１４６の上面図および側面図である。
縦枠カバー部材１４４と下枠カバー部材１４６の構造はほとんど同じであるが、下枠カバー部材１４６の側面には３つの切欠部１５０ａ〜１５０ｃが形成されている点において縦枠カバー部材１４４と相違する。 FIG. 6 is a top view and a side view of the vertical frame cover member 144. FIG. 7 is a top view and a side view of the lower frame cover member 146.
The structures of the vertical frame cover member 144 and the lower frame cover member 146 are almost the same, but are different from the vertical frame cover member 144 in that three notches 150a to 150c are formed on the side surface of the lower frame cover member 146. To do.

切欠部１５０の意味を説明するために、いったん図３に戻る。内障子１２６の外表面を流れ落ちる雨水は、いったん下枠カバー部材１４６の上に落ちる。下枠１２０の上面には図示しない取水口が形成されている。下枠カバー部材１４６の切欠部１５０ａ〜１５０ｃ（図７）から下枠カバー部材１４６の中に流れ込んだ雨水は、下枠１２０の取水口から下枠カバー部材１４６の内部（下枠芯材１４２のある空間）にも流れ込み（図３）、そこから排水される。このように、切欠部１５０は、サッシ窓１００の排水性をよくするために設けられている。   In order to explain the meaning of the notch 150, the description returns to FIG. The rainwater that flows down the outer surface of the inner impeller 126 once falls on the lower frame cover member 146. A water intake (not shown) is formed on the upper surface of the lower frame 120. Rainwater that flows into the lower frame cover member 146 from the notches 150 a to 150 c (FIG. 7) of the lower frame cover member 146 passes through the intake of the lower frame 120 to the inside of the lower frame cover member 146 (of the lower frame core member 142. It flows into a certain space (Fig. 3) and drains from there. Thus, the notch 150 is provided to improve the drainage of the sash window 100.

図８は、ストッパー１３６の拡大斜視図である。図９は、ストッパー１３６の拡大上面図である。
ストッパー１３６は、内側レール１３２の左枠１１４側の端部を覆うことにより、内障子１２６の移動を規制する。本実施形態におけるストッパー１３６は、縦枠カバー部材１４４を通すための切欠部１５２を備える。ストッパー１３６に切欠部１５２を設けることにより、縦枠カバー部材１４４をストッパー１３６に差し込むことができる。このため、より長い縦枠カバー部材１４４を利用でき、また、縦枠カバー部材１４４の下端部を下枠１２０の上面だけでなくストッパー１３６でも覆うことができるので、縦枠カバー部材１４４により形成される筒状空間１４８の密封性を高めることができる。これにより、縦枠カバー部材１４４による断熱効果をいっそう高めることができる。 FIG. 8 is an enlarged perspective view of the stopper 136. FIG. 9 is an enlarged top view of the stopper 136.
The stopper 136 covers the end of the inner rail 132 on the left frame 114 side, thereby restricting the movement of the inner limb 126. The stopper 136 in the present embodiment includes a notch 152 for allowing the vertical frame cover member 144 to pass therethrough. By providing the notch 152 in the stopper 136, the vertical frame cover member 144 can be inserted into the stopper 136. For this reason, the longer vertical frame cover member 144 can be used, and the lower end portion of the vertical frame cover member 144 can be covered not only by the upper surface of the lower frame 120 but also by the stopper 136, so that the vertical frame cover member 144 is formed. The sealing property of the cylindrical space 148 can be improved. Thereby, the heat insulation effect by the vertical frame cover member 144 can further be improved.

以上、実施形態に基づいてサッシ窓１００、特に、縦枠カバー部材１４４と下枠カバー部材１４６について説明した。
樹脂の枠体１１２は、押し出し成形された枠部材から左枠１１４、上枠１１６、右枠１１８、下枠１２０を作るため、これらは同一構造となる。このため、縦枠カバー部材１４４のような断熱構造をはじめから枠部材に形成すると、上枠１１６ではその断熱構造が障子１１０を嵌め込むときの邪魔になる可能性がある。本実施形態においては、特に、熱を逃がしやすい左枠１１４に縦枠カバー部材１４４を後から追加することで、左枠１１４の断熱性能を選択的に強化している。後付け方式の断熱強化であるため、必要な箇所に最適な大きさの断熱強化部材を付加できる。特に、半外付け窓の場合には、熱の逃げ道を効果的に塞ぎやすい。 The sash window 100, particularly the vertical frame cover member 144 and the lower frame cover member 146 have been described based on the embodiment.
Since the resin frame 112 forms the left frame 114, the upper frame 116, the right frame 118, and the lower frame 120 from the extruded frame member, they have the same structure. For this reason, if the heat insulating structure such as the vertical frame cover member 144 is formed on the frame member from the beginning, the heat insulating structure on the upper frame 116 may interfere with the insertion of the shoji 110. In the present embodiment, in particular, the thermal insulation performance of the left frame 114 is selectively enhanced by adding a vertical frame cover member 144 later to the left frame 114 from which heat is easily released. Since it is a retrofitting heat insulation reinforcement, a heat insulation reinforcement member of an optimal size can be added to a necessary location. In particular, in the case of a semi-external window, it is easy to effectively block the heat escape path.

枠体１１２は樹脂成形品であるため、アルミニウムの枠体１１２よりも複雑な成形が可能である。図４に示したように、左枠１１４にツメを設け、ここに縦枠カバー部材１４４のツメを噛み合わせることにより、ワンタッチで縦枠カバー部材１４４を追加できる。また、ストッパー１３６に切欠部１５２を設けることで縦枠カバー部材１４４の断熱効果をいっそう高めている。   Since the frame body 112 is a resin molded product, it can be formed more complicated than the aluminum frame body 112. As shown in FIG. 4, the vertical frame cover member 144 can be added with one touch by providing a claw on the left frame 114 and engaging the claw of the vertical frame cover member 144 therewith. Further, by providing the stopper 136 with the notch 152, the heat insulating effect of the vertical frame cover member 144 is further enhanced.

枠体１１２の内部に複数の閉鎖空間を作れば枠体１１２の断熱性能は向上するが、製造が難しくなるためコストアップ要因になりやすい。本実施形態においては、枠体１１２そのものの構造はシンプルでありながら、断熱効果を高めやすい場所に断熱強化部材を簡単に追加できるため、コストを抑制しつつ断熱性能の向上を図ることができる点に優位性がある。   If a plurality of closed spaces are created inside the frame body 112, the heat insulation performance of the frame body 112 is improved, but the manufacturing becomes difficult, and this tends to be a cost increase factor. In the present embodiment, since the structure of the frame body 112 itself is simple, a heat insulation reinforcing member can be easily added to a place where the heat insulation effect can be easily improved, so that the heat insulation performance can be improved while suppressing costs. Has an advantage.
