アルミニウム合金製の室外部材（形材）および室内部材（形材）を、樹脂材料などからなる断熱材で連結した断熱形材を用いて障子の框を構成した断熱サッシが知られている（例えば、特許文献１参照）。 There is known a heat insulating sash in which an outdoor member (shape member) made of an aluminum alloy and an indoor member (shape member) are connected by a heat insulating material made of a resin material or the like to form a shoji screen (for example, , See Patent Document 1).

特開平７−３０５５６６号公報JP-A-7-305556

しかしながら、前記断熱形材では、室外部材および室内部材は、各部材にかしめ等で固定された断熱材のみで連結され、摺動片や端部キャップ等の框の端部に設けられた端部部材は室内外部材の連結には使用されていない。そして、断熱材は、板状に形成されているので、断熱形材に曲げ方向やねじり方向の力が加わった場合には、断熱材部分が湾曲・変形することがあった。このため、曲げ・ねじり剛性を向上した断熱形材が求められていた。 However, in the heat insulating shape member, the outdoor member and the indoor member are connected only by the heat insulating material fixed to each member by caulking or the like, and are provided at the end portions of the scissors such as sliding pieces and end caps. The member is not used to connect the indoor and outdoor members. And since the heat insulating material is formed in plate shape, when the force of the bending direction or the twist direction was added to the heat insulating shape member, the heat insulating material part might be bent and deformed. For this reason, there has been a demand for a heat insulating shape with improved bending / torsional rigidity.

本発明の目的は、断熱形材が用いられたサッシ窓において、断熱形材の曲げ・ねじり剛性を向上することができるサッシ窓を提供することにある。 The objective of this invention is providing the sash window which can improve the bending and torsional rigidity of a heat insulation shape member in the sash window using the heat insulation shape member.

本発明は、上枠、下枠および左右の縦枠で構成された窓枠と、上框、下框および左右の竪框で構成された障子とを備えたサッシ窓であって、前記上框、下框、左右の竪框のうちの少なくとも１つの框は、金属製の室外部材および室内部材と、前記室外部材および室内部材に跨って配置された断熱ブリッジ材とを備えた断熱形材で構成され、この断熱形材の端部には、前記室外部材および室内部材に跨って配置されて室外部材および室内部材の端部の間隔が広がらないように規制する断熱材からなる端部部材が設けられていることを特徴とする。 The present invention is a sash window comprising a window frame composed of an upper frame, a lower frame and left and right vertical frames, and a shoji composed of an upper frame, a lower frame and left and right frames, And at least one of the left and right saddles is a heat insulating shape member comprising a metal outdoor member and an indoor member, and a heat insulating bridge member disposed across the outdoor member and the indoor member. And an end member made of a heat insulating material that is disposed across the outdoor member and the indoor member and regulates the interval between the outdoor member and the indoor member so as not to widen. It is provided.

ここで、断熱ブリッジ材および断熱材からなる端部部材は、少なくとも、金属製の室外部材、室内部材に比べて熱伝導率が低い材料（断熱材）で構成された部材であればよく、例えば、ウレタン樹脂や塩化ビニル樹脂等の熱伝導率が小さく、熱を通しにくい合成樹脂等で構成されたものが利用できる。 Here, the end member made of the heat insulating bridge material and the heat insulating material may be a member made of a material (heat insulating material) having a lower thermal conductivity than at least the metal outdoor member and the indoor member, for example, In addition, those composed of a synthetic resin such as urethane resin or vinyl chloride resin that has a low thermal conductivity and is difficult to pass heat can be used.

このようなサッシ窓では、断熱形材の端面に設けられた端部部材を各室外部材および室内部材に跨って配置し、各室外部材、室内部材に係合したり、ビス等で固定することで室外部材および室内部材の端部間隔が広がらないようにしているため、断熱形材の曲げ・ねじり剛性を向上できる。特に、端部部材は、断熱形材の端部に配置され、断熱形材つまり断熱ブリッジ材の長手方向に対し、直交方向に配置されるため、断熱形材の曲げ・ねじり剛性を効果的に向上できる。
さらに、端部部材は、断熱性の部材で構成されているので、室外部材および室内部材に跨って配置されていても、断熱性を低下させることが無く、断熱形材つまりはサッシ窓の断熱性能を十分に維持できる。 In such a sash window, the end member provided on the end face of the heat insulating shape member is disposed across each outdoor member and the indoor member, and is engaged with each outdoor member, the indoor member, or fixed with a screw or the like. Therefore, the end-to-end spacing between the outdoor member and the indoor member is not increased, so that the bending / torsional rigidity of the heat insulating shape can be improved. In particular, the end member is disposed at the end of the heat insulating shape member and is disposed in a direction orthogonal to the longitudinal direction of the heat insulating shape member, that is, the heat insulating bridge material, so that the bending and torsional rigidity of the heat insulating shape member is effectively improved. It can be improved.
Furthermore, since the end member is composed of a heat insulating member, even if it is disposed across the outdoor member and the indoor member, the heat insulating property is not deteriorated, that is, the heat insulating shape, that is, the heat insulation of the sash window. Sufficient performance can be maintained.

なお、障子では、通常、左右の竪框間に上框および下框を連結しているので、端部部材は障子の外周面に露出する竪框の上下端面のみに取り付ければよく、竪框に接合される上框や下框の端部には取り付ける必要がない。一方、上框および下框間に竪框を連結した場合には、上框および下框の左右両端部に端部部材を取り付ければよい。
また、本発明においては、断熱ブリッジ材は、室外部材および室内部材のポケット部に断熱材を充填して形成してもよいし、予め成形された略板状の断熱ブリッジ材によって形成してもよい。 In a shoji, the upper and lower heels are usually connected between the left and right heels, so the end members only need to be attached to the upper and lower ends of the heel exposed on the outer peripheral surface of the shoji. It is not necessary to attach to the ends of the upper and lower eyelids to be joined. On the other hand, when a collar is connected between the upper collar and the lower collar, end members may be attached to the left and right ends of the upper collar and the lower collar.
Further, in the present invention, the heat insulating bridge material may be formed by filling the pocket portions of the outdoor member and the indoor member with the heat insulating material, or may be formed by a substantially plate-shaped heat insulating bridge material formed in advance. Good.

さらに、予め成形された断熱ブリッジ材を用いる場合には、室外部材および室内部材のポケット部に挿入のみして取り付けてもよいし、挿入した上でかしめることで固定してもよい。すなわち、断熱ブリッジ材を室外部材および室内部材の両方にかしめによって固定すれば、断熱材を充填した場合と同様に、端部部材だけでなく断熱ブリッジ材によっても室内外部材間が連結されるため、連結強度が向上し、断熱形材の剛性がより向上できる。
また、断熱ブリッジ材は室外部材または室内部材の一方のみにかしめによって固定してもよいし、いずれの部材に対してもかしめないでポケット部に挿通のみしてもよく、要するに、断熱ブリッジ材を室外部材および室内部材の少なくとも一方に対してその長手方向にスライド移動可能に設けてもよい。 Furthermore, in the case of using a preliminarily molded heat insulating bridge material, it may be attached only by being inserted into the outdoor member and the pocket portion of the indoor member, or may be fixed by caulking after being inserted. That is, if the heat insulating bridge material is fixed to both the outdoor member and the indoor member by caulking, the indoor and outdoor members are connected not only by the end member but also by the heat insulating bridge material as in the case where the heat insulating material is filled. The connection strength is improved and the rigidity of the heat insulating shape can be further improved.
Further, the heat insulating bridge material may be fixed to only one of the outdoor member or the indoor member by caulking, or may be only inserted into the pocket portion without being caulked to any member. It may be provided so as to be slidable in the longitudinal direction with respect to at least one of the outdoor member and the indoor member.

ここで、前記室外部材および室内部材にはポケット部が形成され、前記端部部材は各ポケット部に係合固定されて前記室外部材および室内部材の間隔を一定に保持していることが好ましい。
端部部材によって室内外部材の間隔が開かないように保持する手段としては、例えば、端部部材を室内外部材にそれぞれビス止めすることなどでも可能であるが、室内外部材にポケット部を形成し、このポケット部に端部部材を係合固定すれば、端部部材を容易に取り付けることができ、簡単な構造で室内外部材間の間隔も一定に保持できる。 Here, it is preferable that a pocket portion is formed in the outdoor member and the indoor member, and the end member is engaged and fixed to each pocket portion to keep a constant interval between the outdoor member and the indoor member.
As means for holding the end member so that the space between the indoor and outdoor members is not opened, for example, the end member can be screwed to the indoor / outdoor member, but a pocket portion is formed in the indoor / outdoor member. If the end member is engaged and fixed in the pocket portion, the end member can be easily attached, and the space between the indoor and outdoor members can be kept constant with a simple structure.

また、前記ポケット部は、室外部材および室内部材の長手方向全長に渡って形成され、前記断熱ブリッジ材が挿入されるポケット部を兼用していることが好ましい。
端部部材が係合固定されるポケット部を、室内外部材において断熱ブリッジ材が挿入されるポケット部と兼用すれば、室外部材および室内部材の構成は従来のものと同一にでき、前記ポケット部に係合される係合部を有する端部部材を新規に用意するだけで本発明を実現できるので、コスト増加を最小限に抑えることができ、断熱形材の剛性を安価にかつ容易に向上できる。 Moreover, it is preferable that the said pocket part is formed over the longitudinal direction full length of an outdoor member and an indoor member, and also serves as the pocket part in which the said heat insulation bridge | bridging material is inserted.
If the pocket portion to which the end member is engaged and fixed is also used as the pocket portion into which the heat insulating bridge material is inserted in the indoor / outdoor member, the configuration of the outdoor member and the indoor member can be the same as the conventional one, and the pocket portion Since the present invention can be realized simply by newly preparing an end member having an engaging portion to be engaged with the housing, the increase in cost can be minimized and the rigidity of the heat insulating shape can be easily improved at low cost. it can.

さらに、前記上枠および下枠には障子を案内する上レールおよび下レールがそれぞれ形成され、前記上框、下框、左右の竪框のうちの少なくとも竪框は、金属製の室外部材および室内部材と、前記室外部材および室内部材に跨って配置された断熱ブリッジ材とを備えた断熱形材で構成され、前記各端部部材は、竪框の上下両端に取り付けられて前記各レールに対して摺動される上部側摺動片および下部側摺動片で構成されていることが好ましい。 Further, an upper rail and a lower rail for guiding a shoji are formed on the upper frame and the lower frame, respectively, and at least one of the upper rod, the lower rod, and the left and right rods includes a metal outdoor member and an indoor Each of the end members is attached to the upper and lower ends of the eaves with respect to each of the rails. It is preferable that the upper side sliding piece and the lower side sliding piece are slid.

摺動片によって端部部材を兼用していれば、新規な端部部材を別途用意する必要がなく、従来から用いられている摺動片の構造を一部修正するだけでよいので、部品点数の増加を抑えることができ、コスト増加も抑えることができる。 If the sliding piece also serves as an end member, there is no need to prepare a new end member separately, and it is only necessary to partially modify the structure of the sliding piece that has been used in the past. Increase, and cost increase can also be suppressed.

The wall portions 51 and 52 are integrally formed with cover portions 51A and 52A that cover the upper end surfaces of the outdoor member 25A and the indoor member 25B.

そして、上部側摺動片５０の各壁部５１，５２には、竪框２５の室外部材２５Ａおよび室内部材２５Ｂの各ポケット部４０の係合溝４３に係合する係合部５５，５６を備えている。
係合部５５，５６は、図７，８に示すように、係合溝４３の幅寸法に比べて幅寸法が小さい挿入ガイド部５５Ａと、幅寸法が拡大する幅拡大部５５Ｂと、幅寸法が係合溝４３の幅寸法と略同一とされた嵌合部５５Ｃとを備えている。このため、係合部５５，５６をポケット部４０に差し込んだ当初は、挿入ガイド部５５Ａが係合溝４３に挿入されるため、係合溝４３と係合部５５，５６の中心軸が多少ずれていてもスムーズに差し込むことができる。そして、さらに上部側摺動片５０を押し込むと、幅拡大部５５Ｂによって軸合わせが行われた後、係合溝４３に嵌合部５５Ｃが圧入嵌合される。
従って、上部側摺動片５０は、断熱ブリッジ材２５Ｃと同様に、各ポケット部４０に係合して各室外部材２５Ａ、室内部材２５Ｂを連結している。
なお、図示しないが、他の竪框２６、内召合せ框２８に取り付けられる上部側摺動片５０や、各竪框２５，２６、内召合せ框２８に取り付けられる下部側摺動片６０においても、各ポケット部４０に係合する係合部が形成され、この係合部を係合溝４３に嵌合することで各室外部材２５Ａ，２６Ａ，２８Ａ、室内部材２５Ｂ，２６Ｂ，２８Ｂを連結している。 The wall portions 51 and 52 of the upper sliding piece 50 are provided with engaging portions 55 and 56 that engage with the engaging grooves 43 of the outdoor member 25A of the flange 25 and the pocket portions 40 of the indoor member 25B. I have.
As shown in FIGS. 7 and 8, the engaging portions 55 and 56 are, as shown in FIGS. Is provided with a fitting portion 55 C substantially the same as the width dimension of the engaging groove 43. For this reason, when the engaging portions 55 and 56 are initially inserted into the pocket portion 40, the insertion guide portion 55A is inserted into the engaging groove 43, so that the central axes of the engaging groove 43 and the engaging portions 55 and 56 are somewhat different. Even if it is displaced, it can be inserted smoothly. When the upper side sliding piece 50 is further pushed in, axial alignment is performed by the width expanding portion 55 B, and then the fitting portion 55 C is press-fitted into the engagement groove 43.
Accordingly, the upper sliding piece 50 engages with each pocket portion 40 to connect each outdoor member 25A and the indoor member 25B, similarly to the heat insulating bridge member 25C.
Although not shown, in the upper side sliding piece 50 attached to the other basket 26 and the inner summoning bowl 28 and the lower side sliding piece 60 attached to each of the collars 25 and 26 and the inner summing bowl 28, In addition, an engagement portion that engages with each pocket portion 40 is formed, and by engaging this engagement portion with the engagement groove 43, each of the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B are connected. is doing.

なお、上部側摺動片５０、下部側摺動片６０の各係合部５５，５６は、ポケット部４０に圧入するだけでもよいし、圧入後、ポケット部４０をかしめることでより強固に固定してもよい。
また、各断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃは、ポケット部４０に挿通するだけでもよいし、ポケット部４０に挿通後、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃの長手方向の一端側のみをかしめによって固定してもよく、さらには従来と同様に、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃの長手方向全長に渡ってかしめを行って固定してもよいが、本実施形態では、一端部側のみをかしめによって固定している。 It should be noted that the engaging portions 55 and 56 of the upper side sliding piece 50 and the lower side sliding piece 60 may be merely press-fitted into the pocket portion 40, or more firmly by caulking the pocket portion 40 after press-fitting. It may be fixed.
Moreover, each heat insulation bridge | bridging material 21C-26C, 28C may just penetrate the pocket part 40, and after inserting in the pocket part 40, it fixes only one end side of the longitudinal direction of the heat insulation bridge | bridging material 21C-26C, 28C by caulking. Further, as in the conventional case, it may be fixed by caulking over the entire length in the longitudinal direction of the heat insulating bridge members 21C to 26C, 28C, but in this embodiment, only one end side is caulked. It is fixed.

すなわち、本実施形態では、各竪框２５，２６、内召合せ框２８に取り付けられる断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃは、下端部側つまり下部側摺動片６０の上側に隣接して配置される部分のみがかしめによって固定されている。例えば、テラス窓のように、障子２０Ａ，２０Ｂの高さ寸法が約２メートルと高く、各断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃの高さ（長手）寸法も同様に２メートル近くある場合でも、その下端縁から約１０センチメートル程度の高さ範囲内のみでかしめを行っている。 In other words, in the present embodiment, the heat insulating bridge members 25C, 26C, and 28C attached to the respective scissors 25 and 26 and the inner summon scissors 28 are arranged adjacent to the lower end side, that is, the upper side of the lower sliding piece 60. Only the part to be fixed is fixed by caulking. For example, even if the height of the shoji 20A, 20B is as high as about 2 meters and the height (longitudinal) size of each heat insulating bridge member 25C, 26C, 28C is also close to 2 meters like a terrace window, Caulking is performed only within a height range of about 10 centimeters from the lower edge.

このかしめの領域は、かしめを行う数によって設定される。すなわち、各かしめ箇所は、１センチメートル程度の間隔で行うため、例えば、１０個のかしめを行えば、かしめが行われた領域は約１０センチメートル程度となる。また、かしめ数が多くなるほど連結強度が向上するので、かしめ数は必要となる連結強度に応じて設定される。この断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃ部分のかしめは、主に、障子２０Ａ，２０Ｂが搬送中などに誤って落下した際の衝撃で、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂが長手方向にずれてしまうことを防止するものである。従って、上部側摺動片５０や下部側摺動片６０をかしめておくこと等で前記衝撃を支持できるように設計している場合には、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃ部分をかしめる必要はないし、かしめが必要な場合でも、どの程度支持すればよいかによってそのかしめ数を設定すればよい。 This caulking area is set by the number of caulking. That is, since each caulking location is performed at intervals of about 1 cm, for example, if 10 caulking is performed, the area where caulking is performed is about 10 cm. Further, since the connection strength increases as the number of caulking increases, the number of caulking is set according to the required connection strength. The caulking of the heat insulating bridge members 25C, 26C, and 28C is mainly due to an impact when the shojis 20A and 20B are accidentally dropped during transportation or the like, and the outdoor members 25A, 26A, and 28A and the indoor members 25B, 26B, and 28B. Is prevented from shifting in the longitudinal direction. Accordingly, when the upper side sliding piece 50 and the lower side sliding piece 60 are caulked so as to be able to support the impact, the heat insulating bridge members 25C, 26C and 28C need to be caulked. Even if caulking is necessary, the number of caulking may be set depending on how much support is required.

また、上框２１，２２、下框２３，２４に取り付けられる断熱ブリッジ材２１Ｃ〜２４Ｃは、左右両端のうち、外召合せ框２７、内召合せ框２８側の端部のみがかしめによって固定されている。このかしめ数も必要な強度によって設定すれば良い。 Moreover, as for the heat insulation bridge | bridging materials 21C-24C attached to the upper cage | baskets 21 and 22 and the lower cage | baskets 23 and 24, only the edge part by the side of the outer summoning basket 27 and the inner summoning basket 28 is fixed by crimping. ing. This caulking number may be set according to the required strength.

合成樹脂製の断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃは、温度変化に伴う伸縮量がアルミニウム合金製の室外部材２１Ａ〜２６Ａ，２８Ａ、室内部材２１Ｂ〜２６Ｂ，２８Ｂに比べて大きい。このため、夏や昼間など、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃの温度が上昇すると、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃはかしめによって固定されていない上端側が上方つまり上部側摺動片５０側に伸張し、断熱ブリッジ材２１Ｃ〜２４Ｃは竪框２５，２６側の端部が竪框２５，２６側つまり竪框２５，２６に取り付けられた上部側摺動片５０や下部側摺動片６０側に伸張する。
このため、本実施形態では、伸張時に断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃが上部側摺動片５０や下部側摺動片６０に衝突しないように、予め上部側摺動片５０や下部側摺動片６０との間に隙間（クリアランス）７１，７２が設けられている。 The heat insulating bridge members 21C to 26C and 28C made of synthetic resin have a larger amount of expansion and contraction due to temperature change than the outdoor members 21A to 26A and 28A and the indoor members 21B to 26B and 28B made of aluminum alloy. For this reason, when the temperature of the heat insulating bridge members 21C to 26C, 28C rises in summer or daytime, the upper end side of the heat insulating bridge members 25C, 26C, 28C that is not fixed by caulking extends upward, that is, toward the upper sliding piece 50 side. In addition, the end portions of the heat insulating bridge members 21C to 24C on the side of the flanges 25 and 26 are located on the side of the flanges 25 and 26, that is, on the upper side sliding piece 50 or the lower side sliding piece 60 attached to the side walls 25 and 26. Stretch.
For this reason, in the present embodiment, the upper-side sliding piece 50 and the lower-side sliding are previously provided so that the heat insulating bridge members 21C to 26C and 28C do not collide with the upper-side sliding piece 50 and the lower-side sliding piece 60 during extension. Gaps (clearances) 71 and 72 are provided between the piece 60.

具体的には、断熱ブリッジ材２１Ｃ〜２４Ｃは、各框２１〜２４の外召合せ框２７、内召合せ框２８側の端縁が、各框２１〜２４の端縁と面一となるように配置され、その端縁側がかしめによって固定されている。一方、断熱ブリッジ材２１Ｃ〜２４Ｃの竪框２５，２６側の端縁は、図４（Ａ）に示すように、各框２１〜２４の端縁までは延長されておらず、端縁から所定の寸法Ｌ１だけ離れた位置までしか設けられていない。つまり、断熱ブリッジ材２１Ｃ〜２４Ｃの長さ寸法は、基準温度の状態で、各框２１〜２４の室外部材２１Ａ〜２４Ａ、室内部材２１Ｂ〜２４Ｂに比べて寸法Ｌ１だけ短くされ、断熱ブリッジ材２１Ｃ〜２４Ｃと、上部側摺動片５０および下部側摺動片６０との間には、隙間７１が設けられている。
このため、図４（Ｂ）に示すように、温度が上昇して断熱ブリッジ材２１Ｃ〜２４Ｃが伸張しても、各摺動片５０，６０に対して寸法Ｌ２の隙間７１が残り、摺動片５０，６０に衝突することがないように構成されている。 Specifically, in the heat insulating bridge materials 21C to 24C, the end edges of the outer summing rods 27 and the inner summoning rods 28 of the respective ridges 21 to 24 are flush with the end edges of the respective ridges 21 to 24. The edge side is fixed by caulking. On the other hand, as shown in FIG. 4 (A), the edges of the heat insulating bridge members 21C to 24C on the side of the flanges 25 and 26 are not extended to the edges of the flanges 21 to 24, and are predetermined from the edges. It is provided only up to a position separated by the dimension L1. That is, the length dimension of the heat insulating bridge members 21C to 24C is shortened by the dimension L1 as compared with the outdoor members 21A to 24A and the indoor members 21B to 24B of the respective cages 21 to 24 in the state of the reference temperature, and the heat insulating bridge member 21C. A gap 71 is provided between ˜24C and the upper side sliding piece 50 and the lower side sliding piece 60.
For this reason, as shown in FIG. 4B, even if the temperature rises and the heat insulating bridge members 21C to 24C expand, the gap 71 of the dimension L2 remains on the sliding pieces 50 and 60, and the sliding It is comprised so that it may not collide with piece 50,60.

同様に、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃは、下端側が下部側摺動片６０の上端縁に隣接して、その端縁側がかしめによって固定されている。一方、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃの上端側は、図８（Ａ）に示すように、上部側摺動片５０の下端縁から所定の寸法Ｈ１だけ離れた位置までしか設けられていない。つまり、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃの高さ寸法は、基準温度の状態で、各框２５，２６，２８の室外部材２５Ａ，２６Ａ，２８Ａ、室内部材２５Ｂ，２６Ｂ，２８Ｂの高さ寸法に比べて、各摺動片５０，６０の高さ寸法および前記高さ寸法Ｈ１を足した分だけ短くされ、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃと、上部側摺動片５０との間には、隙間７２が設けられている。
このため、図８（Ｂ）に示すように、温度が上昇して断熱ブリッジ材２５Ｃ、２６Ｃ，２８Ｃが伸張しても、上部側摺動片５０に対して高さ寸法Ｈ２の隙間７２が残り、上部側摺動片５０に衝突することがないように構成されている。 Similarly, the heat insulating bridge members 25C, 26C, and 28C are adjacent to the upper end edge of the lower sliding piece 60 on the lower end side, and the end side is fixed by caulking. On the other hand, the upper end sides of the heat insulating bridge members 25C, 26C, and 28C are provided only up to a position away from the lower end edge of the upper sliding piece 50 by a predetermined dimension H1, as shown in FIG. That is, the height dimensions of the heat insulating bridge members 25C, 26C, and 28C are set to the height dimensions of the outdoor members 25A, 26A, and 28A, and the indoor members 25B, 26B, and 28B of each of the scissors 25, 26, and 28 in the state of the reference temperature. Compared with the height dimension of each sliding piece 50, 60 and the height dimension H1, it is shortened, and between the heat insulating bridge members 25C, 26C, 28C and the upper side sliding piece 50, A gap 72 is provided.
Therefore, as shown in FIG. 8B, even if the temperature rises and the heat insulating bridge members 25C, 26C, and 28C expand, a gap 72 having a height dimension H2 remains with respect to the upper sliding piece 50. The upper side sliding piece 50 is configured not to collide.

なお、各断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃが設けられている部分は、レール１６〜１９等に当接するシール材によって室外側から区画されているので、隙間が形成されていても水密性や気密性に影響を与えることはない。また、上下の框２１〜２４や内召合せ框２８部分の隙間７１，７２は、サッシ窓の使用時には利用者が視認することができないため、意匠性を低下させることもない。
但し、竪框２５，２６部分に生じる隙間７２は、障子２０Ａ，２０Ｂを開いた際に、その側面に露出するため、利用者が視認することができる。このため、上部側摺動片５０には、断熱ブリッジ材２５Ｃ，２６Ｃの外側面側に配置されて前記隙間７２部分を被覆する被覆片５７が下方に突出して形成されている。 In addition, since the part in which each heat insulation bridge | bridging material 21C-26C, 28C is provided is divided from the outdoor side by the sealing material contact | abutted to the rails 16-19 etc., even if a clearance gap is formed, watertightness or airtightness Does not affect sex. Moreover, since the user cannot visually recognize the upper and lower ridges 21 to 24 and the gaps 71 and 72 in the inner summon ridge 28, the design is not deteriorated.
However, since the gap 72 generated in the flanges 25 and 26 is exposed to the side surfaces when the shojis 20A and 20B are opened, the user can visually recognize them. For this reason, the upper-side sliding piece 50 is formed with a covering piece 57 that is disposed on the outer surface side of the heat insulating bridge members 25C and 26C and covers the gap 72 portion.

このような本実施形態によれば、以下のような効果がある。
(1) 障子２０Ａ，２０Ｂの竪框２５，２６、内召合せ框２８の上下両端に設けられる端部部材である上部側摺動片５０、下部側摺動片６０を各室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂに跨って配置して各ポケット部４０に係合したので、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂ間の連結強度を向上でき、竪框２５，２６、内召合せ框２８の曲げ・ねじり剛性を向上できる。
また、上部側摺動片５０、下部側摺動片６０は、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂの長手方向に直交する面状に形成されているので、室内部材２５Ｂ，２６Ｂ，２８Ｂに対して室外部材２５Ａ，２６Ａ，２８Ａが軸直交方向に曲げられたり、ねじられたりした際に、各上部側摺動片５０、下部側摺動片６０でその力を支持できるので、各竪框２５，２６や内召合せ框２８の曲げ剛性やねじり剛性を効果的に向上できる。特に、摺動片５０，６０は、それぞれ２本の係合部５５，５６を備え、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂにそれぞれ２カ所で係合されているので、各框２５，２６，２８の曲げ剛性やねじり剛性をより一層向上できる。 According to this embodiment, there are the following effects.
(1) The upper side sliding piece 50 and the lower side sliding piece 60, which are end members provided at the upper and lower ends of the shojis 25A and 26 of the shoji 20A and 20B, and the inner summoning gore 28, are respectively connected to the outdoor members 25A and 26A. , 28A and the indoor members 25B, 26B, 28B and engaged with the pocket portions 40, the connection strength between the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B can be improved. The bending / torsional rigidity of the collars 25 and 26 and the inner summon bowl 28 can be improved.
Moreover, since the upper side sliding piece 50 and the lower side sliding piece 60 are formed in a plane shape orthogonal to the longitudinal direction of the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B, the indoor member 25B. , 26B, 28B, when the outdoor members 25A, 26A, 28A are bent or twisted in the direction perpendicular to the axis, the upper side sliding pieces 50 and the lower side sliding pieces 60 can support the force. Therefore, the bending rigidity and torsional rigidity of each of the collars 25 and 26 and the inner summoning collar 28 can be effectively improved. In particular, the sliding pieces 50 and 60 have two engaging portions 55 and 56, respectively, and are engaged with the outdoor members 25A, 26A and 28A and the indoor members 25B, 26B and 28B at two locations, respectively. The bending rigidity and torsional rigidity of each flange 25, 26, 28 can be further improved.

(2) 上部側摺動片５０、下部側摺動片６０は、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂにおいて断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃが挿入されるポケット部４０に、係合部５５，５６を係合しているので、摺動片５０，６０を係合するための新たなポケット部を別途形成する必要がない。このため、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂは従来と同一のものを利用でき、上部側摺動片５０、下部側摺動片６０のみを新規に用意すればよいため、コスト増加を最小限に抑えることができ、断熱形材の剛性を安価にかつ容易に向上できる。 (2) The upper side sliding piece 50 and the lower side sliding piece 60 are provided in the pocket portion 40 in which the heat insulating bridge members 25C, 26C, and 28C are inserted in the outdoor members 25A, 26A, and 28A and the indoor members 25B, 26B, and 28B. Since the engaging portions 55 and 56 are engaged, it is not necessary to separately form a new pocket portion for engaging the sliding pieces 50 and 60. Therefore, the outdoor members 25A, 26A, and 28A and the indoor members 25B, 26B, and 28B can be the same as the conventional ones, and only the upper side sliding piece 50 and the lower side sliding piece 60 need be newly prepared. Therefore, the increase in cost can be minimized, and the rigidity of the heat insulating shape can be improved inexpensively and easily.

(3) 上部側摺動片５０、下部側摺動片６０は、ポケット部４０に圧入嵌合し、適宜かしめるだけでよいので、ビスなどで固定する場合に比べて取付作業も容易に行うことができる。さらに、各摺動片５０，６０の係合部５５，５６を、幅寸法の異なる挿入ガイド部５５Ａ、幅拡大部５５Ｂ、嵌合部５５Ｃで構成したので、係合部５５，５６を容易にポケット部４０に挿入することができ、この点でも取付作業性を向上できる。 (3) Since the upper side sliding piece 50 and the lower side sliding piece 60 need only be press-fitted into the pocket 40 and caulked as appropriate, the mounting work can be performed more easily than when fixed with screws or the like. be able to. Furthermore, since the engaging portions 55 and 56 of the sliding pieces 50 and 60 are constituted by the insertion guide portion 55A, the width expanding portion 55B and the fitting portion 55C having different width dimensions, the engaging portions 55 and 56 can be easily formed. It can be inserted into the pocket portion 40, and the mounting workability can be improved in this respect.

(4) 本実施形態では、摺動片５０，６０が、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂを連結する端部部材を兼用しているので、端部部材を別途用意する必要がなく、従来から用いられている摺動片５０，６０の構造を一部修正するだけでよいので、部品点数の増加を抑えることができ、コスト増加も抑えることができる。 (4) In the present embodiment, the sliding pieces 50, 60 also serve as end members for connecting the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B. There is no need to do this, and it is only necessary to partially modify the structure of the sliding pieces 50 and 60 that have been used conventionally, so that an increase in the number of parts can be suppressed and an increase in cost can also be suppressed.

(5) 摺動片５０，６０で室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂを連結しているので、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃは全長に渡ってかしめる必要が無く、端部の一部分のみをかしめればよいため、かしめ作業が軽減され、生産性も向上できる。 (5) Since the outdoor members 25A, 26A, 28A and the indoor members 25B, 26B, 28B are connected by the sliding pieces 50, 60, the heat insulating bridge members 25C, 26C, 28C do not have to be caulked over the entire length. Since only a part of the end portion needs to be caulked, the caulking work is reduced and the productivity can be improved.

(6) 断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃは、その長手方向の一端側のみをかしめで固定しているので、温度に応じて断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃが伸縮した場合に、室外部材２１Ａ〜２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂに対して断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃを自由にスライド移動させることができる。
このため、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃが、ポケット部４０に注入固定されている場合や、全長に渡ってかしめられている場合のように、室外部材２１Ａ〜２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂの熱伸び量の差によって断熱形材（各框２１〜２６，２８）が反ってしまうことがない。すなわち、本実施形態では、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃは自由にスライド移動できるので、室外部材２１Ａ〜２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂの熱伸び量に差が生じても、各框２１〜２６，２８の反りを防止できる。特に、寸法が大きく長尺な竪框２５，２６，２８においても効果的に熱反りを防止できる。 (6) Since the heat insulating bridge members 21C to 26C and 28C are fixed by caulking only one end side in the longitudinal direction, when the heat insulating bridge members 21C to 26C and 28C expand and contract depending on the temperature, the outdoor member 21A The heat insulating bridge members 21C to 26C and 28C can be slid freely with respect to ˜26A and 28A and the indoor members 25B, 26B and 28B.
For this reason, the outdoor members 21A to 26A, 28A and the indoor members 25B, when the heat insulating bridge members 21C to 26C, 28C are injected and fixed in the pocket portion 40, or are caulked over the entire length, The heat insulating shape members (each ridge 21 to 26, 28) do not warp due to the difference in the amount of thermal elongation between 26B and 28B. That is, in this embodiment, since the heat insulating bridge members 21C to 26C and 28C can freely slide and move, each of the outdoor members 21A to 26A and 28A and the indoor members 25B, 26B and 28B has a difference in thermal expansion amount. Warpage of the ridges 21 to 26, 28 can be prevented. In particular, thermal warpage can be effectively prevented even in the case of the large and long ridges 25, 26, and 28.

(7) 各断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃと、上部側摺動片５０、下部側摺動片６０との間には、所定の隙間７１，７２が形成されているので、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃが熱伸びしても各摺動片５０，６０に衝突することを防止でき、衝突によって上部側摺動片５０等が押し上げられることを防止できる。また、衝突により、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃが湾曲することも防止できるので、室外部材２１Ａ〜２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂの端部を自由にスライド移動させることができ、この点でも熱反りの発生を防止できる。 (7) Since predetermined gaps 71 and 72 are formed between each of the heat insulating bridge members 21C to 26C and 28C and the upper side sliding piece 50 and the lower side sliding piece 60, the heat insulating bridge material 21C. Even if .about.26C and 28C are thermally expanded, they can be prevented from colliding with the sliding pieces 50 and 60, and the upper side sliding piece 50 and the like can be prevented from being pushed up by the collision. Further, since it is possible to prevent the heat insulating bridge members 21C to 26C and 28C from being bent due to the collision, the end portions of the outdoor members 21A to 26A and 28A and the indoor members 25B, 26B and 28B can be freely slid, Also in this respect, the occurrence of thermal warpage can be prevented.

(8) 上部側摺動片５０には、被覆片５７が形成されているので、断熱ブリッジ材２５Ｃ，２６Ｃと上部側摺動片５０間の隙間７２を塞ぐことができ、意匠性の低下を防止できる。さらに、断熱ブリッジ材２５Ｃ，２６Ｃは、下端部分をかしめで固定することで、上端部分に隙間７２を形成しているので、下端側に隙間を形成した場合に比べて、利用者が視認し難い箇所に隙間７２を形成することになるので、意匠性をより向上できる。 (8) Since the covering piece 57 is formed on the upper side sliding piece 50, the gap 72 between the heat insulating bridge members 25C, 26C and the upper side sliding piece 50 can be closed, and the design property is reduced. Can be prevented. Furthermore, since the heat insulation bridge members 25C and 26C have the lower end portion thereof fixed by caulking to form the gap 72 at the upper end portion, it is difficult for the user to visually recognize as compared with the case where the gap is formed on the lower end side. Since the gap 72 is formed at the location, the design can be further improved.

なお、本発明は前記各実施形態の構成に限定されるものではない。
例えば、前記実施形態では、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃは一端側をかしめていたが、長手方向全長に渡ってかしめてもよい。この場合には、隙間７１，７２を設ける必要が無く、室外部材２１Ａ〜２６Ａ，２８Ａおよび室内部材２１Ｂ〜２６Ｂ，２８Ｂの連結強度をより一層向上できる。
また、一部分をかしめる場合でも、例えば、断熱ブリッジ材２５Ｃ，２６Ｃ，２８Ｃの上端側や中間部の一部分のみをかしめてもよい。同様に、断熱ブリッジ材２１Ｃ〜２４Ｃの框２５、２６側の端部や中間部の一部分のみをかしめてもよい。但し、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃの中間部をかしめると、その両端部で熱伸びが生じ、それぞれに熱伸びを許容するための隙間を形成しなければならず、組立作業性が低下するため、前記実施形態のように一方の端部をかしめることが好ましい。
さらに、断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃはかしめで固定せずに、ポケット部４０に挿入のみしてもよい。この場合は、上部側摺動片５０、下部側摺動片６０のポケット部４０への係合部分をかしめて連結強度を高めればよい。
また、前記実施形態では、予め成形された板状の断熱ブリッジ材２１Ｃ〜２６Ｃ，２８Ｃを用いていたが、溶融された樹脂をポケット部４０に注入して断熱ブリッジ材を構成してもよい。 In addition, this invention is not limited to the structure of each said embodiment.
For example, in the embodiment, the heat insulating bridge members 21C to 26C and 28C are caulked on one end side, but may be caulked over the entire length in the longitudinal direction. In this case, it is not necessary to provide the gaps 71 and 72, and the connection strength of the outdoor members 21A to 26A and 28A and the indoor members 21B to 26B and 28B can be further improved.
Further, even when a part is caulked, for example, only the upper end side of the heat insulating bridge members 25C, 26C, and 28C or a part of the intermediate part may be caulked. Similarly, you may crimp only the edge part by the side of the collar 25,26 of the heat insulation bridge | bridging materials 21C-24C, or a part of intermediate part. However, if the intermediate portions of the heat insulating bridge members 21C to 26C and 28C are caulked, thermal elongation occurs at both ends thereof, and a gap for allowing thermal elongation must be formed in each of them, resulting in reduced assembly workability. Therefore, it is preferable to caulk one end as in the above embodiment.
Further, the heat insulating bridge members 21C to 26C and 28C may be only inserted into the pocket portion 40 without being fixed by caulking. In this case, the engagement strength of the upper side sliding piece 50 and the lower side sliding piece 60 to the pocket portion 40 may be increased by caulking.
Moreover, in the said embodiment, although the plate-shaped heat insulation bridge | bridging material 21C-26C, 28C shape | molded previously was used, you may comprise the heat insulation bridge | bridging material by inject | pouring the melted resin into the pocket part 40. FIG.

また、窓枠１０の断熱ブリッジ材１１Ｃ〜１４Ｃも、全長にわたってかしめてもよいし、端部や中間部の一部分のみをかしめてもよいし、かしめを行わずポケット部１５に挿入のみしてもよいし、溶融樹脂をポケット部１５に注入して構成してもよい。なお、窓枠１０の各室外部材１１Ａ〜１４Ａ、室内部材１１Ｂ〜１４Ｂはそれぞれ躯体にビス等で固定されているので、これらを連結する断熱ブリッジ材１１Ｃ〜１４Ｃにおける連結強度は輸送時に必要となる程度であり、それほど要求されない。従って、各枠１１〜１４において端部部材で室外部材１１Ａ〜１４Ａ、室内部材１１Ｂ〜１４Ｂを連結する必要はない。 Further, the heat insulating bridge members 11C to 14C of the window frame 10 may be caulked over the entire length, may be caulked only at a part of the end portion or the intermediate portion, or may be only inserted into the pocket portion 15 without being caulked. Alternatively, molten resin may be injected into the pocket portion 15 and configured. In addition, since each outdoor member 11A-14A and indoor member 11B-14B of the window frame 10 are each fixed to the housing with a screw etc., the connection intensity | strength in the heat insulation bridge | bridging material 11C-14C which connects these is needed at the time of transportation. Is not so required. Therefore, it is not necessary to connect the outdoor members 11A to 14A and the indoor members 11B to 14B at the end members in the respective frames 11 to 14.

本発明の端部部材としては、上部側摺動片５０、下部側摺動片６０を用いたものに限らない。例えば、摺動片を備えない開き窓において、障子の框に取り付けられる端部キャップを端部部材として利用してもよい。さらに、上部側摺動片５０、下部側摺動片６０を有する場合でも、これらの摺動片５０，６０とは別に端部部材を設けてもよい。 The end member of the present invention is not limited to those using the upper side sliding piece 50 and the lower side sliding piece 60. For example, in the case of an opening window that does not include a sliding piece, an end cap that is attached to a shoji screen may be used as the end member. Further, even when the upper side sliding piece 50 and the lower side sliding piece 60 are provided, an end member may be provided separately from these sliding pieces 50 and 60.

さらに、端部部材（上部側摺動片５０、下部側摺動片６０）は、室外部材２１Ａ〜２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂのポケット部４０に係合されるものに限らない。例えば、端部部材（摺動片５０，６０）を係合するポケット部を別途設けてもよいし、端部部材をネジで室外部材２１Ａ〜２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂに固定してもよい。要するに、端部部材は、室外部材２５Ａ，２６Ａ，２８Ａおよび室内部材２５Ｂ，２６Ｂ，２８Ｂの間隔を一定に維持でき、各框の端部の開きを防止できるものであればよい。
また、各摺動片５０，６０の材質は、合成樹脂などの熱伝導率が低く、断熱性能を維持できるものであればよく、実施にあたって適宜選択すればよい。
さらに、他の構成、例えば、各框２１〜２８や、各框２１〜２８で保持される面材の具体的な構造・形状や、各枠１１〜１４の構造、躯体への取付構造等は前記実施形態のものに限らない。 Further, the end members (the upper side sliding piece 50 and the lower side sliding piece 60) are not limited to those engaged with the pocket portions 40 of the outdoor members 21A to 26A, 28A and the indoor members 25B, 26B, 28B. . For example, a pocket portion for engaging the end member (sliding pieces 50, 60) may be provided separately, and the end member is fixed to the outdoor members 21A to 26A, 28A and the indoor members 25B, 26B, 28B with screws. May be. In short, the end member may be any member that can maintain a constant interval between the outdoor members 25A, 26A, and 28A and the indoor members 25B, 26B, and 28B and can prevent the end portions of the ridges from opening.
Moreover, the material of each sliding piece 50 and 60 should just be selected suitably in the implementation, as long as it has a low thermal conductivity such as synthetic resin and can maintain the heat insulating performance.
Furthermore, other configurations, for example, the specific structures / shapes of the face materials held by the flanges 21-28, the flanges 21-28, the structures of the frames 11-14, the mounting structure to the frame, etc. The present invention is not limited to the above embodiment.
