Description

本発明は、窓シャッター装置に関するものである。 The present invention relates to a window shutter device.

窓シャッターの下枠に防火性能を持たせる場合には、例えば、窓シャッターの下枠（水切板）に、窓開口部全閉時にシャッターカーテン下端の座板の下方部位を受け入れる凹部を設け、窓開口部全閉時に、下枠と座板の下方部位との間に屋内外を直接貫通する防火防煙上不利な空間が形成されないようにしている。 If the lower frame of the window shutter is to have fire protection performance, for example, the lower frame (drain plate) of the window shutter is provided with a recess for receiving the lower part of the seat plate at the lower end of the shutter curtain when the window opening is fully closed. When the opening is fully closed, a space that is disadvantageous in terms of fire protection and smoke protection that directly penetrates indoors and outdoors is not formed between the lower frame and the lower part of the seat plate.

防火性能が要求される窓シャッターでは、より長い避難時間を確保し、また、延焼をなるべく食い止めるため、耐火性能がより長い時間維持されることが望ましいが、窓シャッターの下枠は、建物の外壁から持ち出し状に設けられているため、窓開口部全閉状態において、屋外側で火災が発生した場合には、火災時の熱によって下枠の屋外側部位及び下面が加熱され、屋外側部位が倒れるように垂れて変形するおそれがある。 For window shutters that require fire protection, it is desirable to maintain fire resistance for a longer period of time in order to secure a longer evacuation time and prevent the spread of fire as much as possible. If a fire breaks out on the outdoor side when the window opening is fully closed, the outdoor side and lower surface of the lower frame will be heated by the heat of the fire, and the outdoor side will be heated. It may hang down and deform.

このような下枠の変形によって、座板の下方部位と下枠との間に室内外を貫通する防火防煙上不利な空間が形成されることや、下枠の垂れ下がりによる座板の抜けを防止するために、下枠の立ち上がり寸法を高くし、座板の下方部位を深く飲み込ませるようにしている（図１７、特許文献１）。 Due to such deformation of the lower frame, a space that penetrates indoors and outdoors is formed between the lower part of the seat plate and the lower frame, and the seat plate is prevented from coming off due to the hanging of the lower frame. In order to prevent this, the rising dimension of the lower frame is increased so that the lower portion of the seat plate is swallowed deeply (FIG. 17, Patent Document 1).

ここで、コストダウンや意匠性の向上等の理由から、窓シャッターにおいて、下枠の立ち上がり寸法を小さくしたい場合がある。しかしながら、下枠の立ち上がり寸法を小さくすることは、すなわち、下枠の凹部の深さが浅くなって、窓開口部全閉時に座板の下方部位の飲み込み寸法が小さくなることを意味し、加熱時の下枠の垂れ下がりによって座板が抜けやすくなってしまうという懸念がある（図８（Ｂ））。
特許第５７８５０３９号 Here, in the window shutter, there is a case where it is desired to reduce the rising dimension of the lower frame for the reason of cost reduction and improvement of design. However, reducing the rising dimension of the lower frame means that the depth of the recess of the lower frame becomes shallower, and the swallowing dimension of the lower portion of the seat plate becomes smaller when the window opening is fully closed. There is a concern that the seat plate will easily come off due to the hanging of the lower frame at the time (Fig. 8 (B)).

And a lower mounting piece 67. The bottom side 62, the outdoor side vertical side 63, and the lower side 64 of the lower frame 6 face the outdoor space.

屋内側垂直辺６１は開口幅方向に延びているが、本実施形態では、開口幅方向両端のガイドレール枠３までは達しておらず、屋外側垂直辺６３よりも短尺である（図３、図１０（Ａ））。屋内側垂直辺６１は、上辺６０から垂直状に立ち上がる上側部位と、上辺６０から垂下する下側部位とからなる。屋内側垂直辺６１と屋外側垂直辺６３との間の空間の上方は開放状となっており、屋外側垂直辺６３と、屋内側垂直辺６１と、底辺６２と、から凹部６００が形成されている。底辺６２には、長孔状の水抜き孔６２０が形成されている。屋外側垂直辺６３の上端には、屋内側に向かって延びる水平片６３０が形成されている。上辺６０、屋内側垂直辺６１の下側部位、下辺６４、後辺６５から中空状の屋内側部位が形成されている。図１７に示す従来例の下枠６´と比較すると明らかなように、本実施形態に係る下枠６（屋外側垂直辺６３）の立ち上がり寸法Ｈ１は、従来の下枠６´（屋外側垂直辺６３´）の立ち上がり寸法Ｈ２よりも小さい。 The indoor side vertical side 61 extends in the opening width direction, but in the present embodiment, it does not reach the guide rail frames 3 at both ends in the opening width direction, and is shorter than the outdoor side vertical side 63 (FIG. 3, FIG. FIG. 10 (A). The indoor vertical side 61 includes an upper portion that rises vertically from the upper side 60 and a lower portion that hangs down from the upper side 60. The upper part of the space between the indoor side vertical side 61 and the outdoor side vertical side 63 is open, and a recess 600 is formed from the outdoor side vertical side 63, the indoor side vertical side 61, and the bottom side 62. ing. A long hole-shaped drain hole 620 is formed in the bottom 62. A horizontal piece 630 extending toward the indoor side is formed at the upper end of the vertical side 63 on the outdoor side. A hollow indoor side portion is formed from the upper side 60, the lower portion of the indoor vertical side 61, the lower side 64, and the rear side 65. As is clear from comparison with the lower frame 6'of the conventional example shown in FIG. 17, the rising dimension H1 of the lower frame 6 (outdoor side vertical side 63) according to the present embodiment is the conventional lower frame 6'(outdoor side vertical side). It is smaller than the rising dimension H2 of the side 63').

本実施形態では、屋外側垂直辺６３の立ち上がり寸法は、屋内側垂直辺６１の立ち上がり寸法よりも大きく、すなわち、屋内側垂直辺６１の上端の高さ位置は、屋外側垂直辺６３の上端の高さ位置よりも低い位置にあるが、この逆でもよい。また、図示の態様では、屋内側垂直辺６１の下側部位が凹部６００の屋内側部位を形成しているが、屋内側垂直辺６１は上辺６０（凹部６００よりも屋内側に位置する部位）から立ち上がる辺であってもよい。また、屋内側垂直辺６１に、例えば屋内側に延びる片を一体形成してもよい。図示の下枠６の形状は一実施例であって、本発明が適用される下枠６の形状や構成は図示のものに限定されない。例えば、底辺６２は下辺６４と一体で水平方向に延びるものでもよい。例えば、図示の下枠６は、一部材から一体形成されているが、複数の部材の組み合わせから下枠を形成してもよい。例えば、下枠６の屋内側部位（上辺６０を備える）を別部材から形成してもよい（屋内側垂直辺６１を別部材から形成してもよい）。 In the present embodiment, the rising dimension of the outdoor vertical side 63 is larger than the rising dimension of the indoor vertical side 61, that is, the height position of the upper end of the indoor vertical side 61 is the upper end of the outdoor vertical side 63. It is lower than the height position, but vice versa. Further, in the illustrated embodiment, the lower portion of the indoor vertical side 61 forms the indoor portion of the recess 600, but the indoor vertical side 61 is the upper side 60 (a portion located on the indoor side of the recess 600). It may be the side that rises from. Further, for example, a piece extending to the indoor side may be integrally formed on the vertical side 61 on the indoor side. The shape of the lower frame 6 shown in the figure is an embodiment, and the shape and configuration of the lower frame 6 to which the present invention is applied are not limited to those shown in the figure. For example, the bottom side 62 may be integrated with the lower side 64 and extend in the horizontal direction. For example, although the lower frame 6 shown in the figure is integrally formed from one member, the lower frame may be formed from a combination of a plurality of members. For example, the indoor side portion (including the upper side 60) of the lower frame 6 may be formed from another member (the indoor side vertical side 61 may be formed from another member).

［座板と下枠］
凹部６００は、シャッターカーテン５の昇降経路の直下に位置しており、窓開口部の全幅を越えてガイドレール枠３の下方にまで達している。凹部６００には、窓開口部全閉状態においてシャッターカーテン５の下端の座板５１の下端部位５１００が受け入れられる。座板５１の下方部位は凹部６００内に受け入れられているので、座板５１の下端と凹部６００の底面との間に隙間が形成されていても、屋内側を直線的に連通する空間は形成されない。窓開口部全閉状態において、座板５１の下端部位５１００は、凹部６００内に位置しており、下端部位５１００の屋外側には、下枠６の屋外側垂直辺６３が位置しており、下端部位５１００は直接屋外側空間には面していない。窓開口部全閉状態において、下枠６の屋内側垂直辺６１は、下端部位５１００の屋内側に位置しており、屋内側垂直辺６１は直接屋外側空間には面していない。屋内側片５１３の第１片５１３０は、下枠６の屋内側垂直辺６１の上端の上方に位置して屋内側に向かって水平に延びており、屋外側部位は凹部６００の上方に位置しており、屋内側部位は上辺６０の上方に位置している。屋内側片５１３の第２片５１３１は、下枠６の屋内側垂直辺６１の屋内側に位置して、屋内側垂直辺６１と離間対向している。 [Seat plate and lower frame]
The recess 600 is located directly below the elevating path of the shutter curtain 5, and extends beyond the entire width of the window opening to the bottom of the guide rail frame 3. In the recess 600, the lower end portion 5100 of the seat plate 51 at the lower end of the shutter curtain 5 is accepted in the state where the window opening is fully closed. Since the lower portion of the seat plate 51 is received in the recess 600, even if a gap is formed between the lower end of the seat plate 51 and the bottom surface of the recess 600, a space that linearly communicates with the indoor side is formed. Not done. In the fully closed state of the window opening, the lower end portion 5100 of the seat plate 51 is located in the recess 600, and the outdoor side vertical side 63 of the lower frame 6 is located on the outdoor side of the lower end portion 5100. The lower end portion 5100 does not directly face the outdoor side space. In the fully closed state of the window opening, the indoor vertical side 61 of the lower frame 6 is located on the indoor side of the lower end portion 5100, and the indoor vertical side 61 does not directly face the outdoor space. The first piece 5130 of the indoor side piece 513 is located above the upper end of the indoor side vertical side 61 of the lower frame 6 and extends horizontally toward the indoor side, and the outdoor side portion is located above the recess 600. The indoor side portion is located above the upper side 60. The second piece 5131 of the indoor side piece 513 is located on the indoor side of the indoor side vertical side 61 of the lower frame 6 and is separated from and opposed to the indoor side vertical side 61.

図１７に示すように、本実施形態に係る下枠６の立ち上がり寸法Ｈ１は、従来の下枠６´の立ち上がり寸法Ｈ２よりも小さく、座板５１の下端部位５１００の高さ寸法は、従来の座板５１´の下端部位５１００´の高さ寸法よりも小さい。図１７に示す下枠６´の立ち上がり寸法や座板５１´の下端部位５１００´の高さ寸法を小さくした場合には、窓開口部全閉時に座板の下方部位の飲み込み寸法が小さくなることから、加熱時の下枠６´´の垂れ下がりによって座板５１が抜けやすくなってしまう（図８（Ｂ））。 As shown in FIG. 17, the rising dimension H1 of the lower frame 6 according to the present embodiment is smaller than the rising dimension H2 of the conventional lower frame 6', and the height dimension of the lower end portion 5100 of the seat plate 51 is the conventional height dimension. It is smaller than the height dimension of the lower end portion 5100'of the seat plate 51'. When the rising dimension of the lower frame 6'and the height dimension of the lower end portion 5100' of the seat plate 51'shown in FIG. 17 are reduced, the swallowing dimension of the lower portion of the seat plate becomes smaller when the window opening is fully closed. Therefore, the seat plate 51 is easily pulled out due to the hanging of the lower frame 6 ″ during heating (FIG. 8 (B)).

これに対して、本実施形態では、窓開口部全閉時において、屋内側片５１３の第２片５１３１は、下枠６の屋内側垂直辺６１の屋内側に位置して、屋内側垂直辺６１と離間対向している。下端部位５１００の屋外側には、下枠６の屋外側垂直辺６３が位置しており、下端部位５１００は直接屋外側空間には面しておらず、座板５１の下端部位５１００の屋内側に屋内側片５１３が形成されていると共に、下端部位５１００の屋内側に屋内側垂直辺６１が位置しており、屋内側片５１３及び屋内側垂直辺６１は直接屋外側空間には面しておらず、加熱時の熱の影響を受けにくい。加熱時に下枠６が垂れ下がるように変形し得るが、下枠６の屋内側垂直辺６１（加熱時の熱の影響を受け難い部位）の上方部位に、座板５１の屋内側片５１３（加熱時の熱の影響を受け難い部位）の第２片５１３１が係止ないし当接することで、座板５１の抜けを可及的に防止する（図８（Ａ））。 On the other hand, in the present embodiment, when the window opening is fully closed, the second piece 5131 of the indoor side piece 513 is located on the indoor side of the indoor side vertical side 61 of the lower frame 6 and is located on the indoor side vertical side. It faces away from 61. The outdoor side vertical side 63 of the lower frame 6 is located on the outdoor side of the lower end portion 5100, the lower end portion 5100 does not directly face the outdoor side space, and the indoor side of the lower end portion 5100 of the seat plate 51. The indoor side piece 513 is formed in the indoor side piece 513, and the indoor side vertical side 61 is located on the indoor side of the lower end portion 5100, and the indoor side piece 513 and the indoor side vertical side 61 directly face the outdoor side space. It is not easily affected by the heat during heating. The lower frame 6 can be deformed so as to hang down during heating, but the indoor side piece 513 (heating) of the seat plate 51 is located above the indoor vertical side 61 (the part that is not easily affected by the heat during heating) of the lower frame 6. The second piece 5131 (a portion that is not easily affected by the heat of the time) is locked or abutted to prevent the seat plate 51 from coming off as much as possible (FIG. 8 (A)).

座板５１の下端部位５１００の屋内側のポケットＰ２には、熱膨張耐火部材（図示せず）が収容されている。火災時の熱で熱膨張耐火部材が膨張すると、熱膨張した熱膨張耐火部材が、座板５１の下端部位５１００の屋内側、底辺６２の上方、屋内側片５１３の第１片５１３０の下側、屋内側垂直辺６１の屋外側で囲まれた空間を開口幅方向に亘って閉塞することで、屋内外空間を連通する隙間が形成されることを防止する。なお、熱膨張耐火部材を第１片５１３０の下面に設けてもよい。 A thermal expansion refractory member (not shown) is housed in a pocket P2 on the indoor side of the lower end portion 5100 of the seat plate 51. When the thermal expansion refractory member expands due to the heat of a fire, the thermally expanded refractory member expands on the indoor side of the lower end portion 5100 of the seat plate 51, above the bottom 62, and below the first piece 5130 of the indoor side piece 513. By closing the space surrounded by the outdoor side of the indoor side vertical side 61 in the opening width direction, it is possible to prevent the formation of a gap communicating with the indoor / outdoor space. The thermal expansion refractory member may be provided on the lower surface of the first piece 5130.

［下枠と窓サッシ下枠］
図９に示すように、下枠６の上側装着片６６は後方に向かって上向き傾斜状に延びており、上端には上側係止片６６０が形成されている。下枠６の下側装着片６７は下向き膨出状の湾曲辺であり、中途部位には下方に向かって延びる下側係止片６７０が形成されている。上側装着片６６には、開口幅方向に間隔を存して複数の挿通孔６８が形成されており、下枠６を窓サッシの下枠１６に固定する螺子Ｓ３を挿通させるようになっている。上側装着片６６には、挿通孔６８の直下に位置して、後方に向かって下向き傾斜状に延びるガイド片６９が形成されている。 [Bottom frame and window sash bottom frame]
As shown in FIG. 9, the upper mounting piece 66 of the lower frame 6 extends rearward in an upwardly inclined manner, and the upper locking piece 660 is formed at the upper end. The lower mounting piece 67 of the lower frame 6 is a curved side having a downward bulge, and a lower locking piece 670 extending downward is formed in the middle portion. A plurality of insertion holes 68 are formed in the upper mounting piece 66 at intervals in the opening width direction, and a screw S3 for fixing the lower frame 6 to the lower frame 16 of the window sash is inserted. .. The upper mounting piece 66 is formed with a guide piece 69 that is located directly below the insertion hole 68 and extends downward in an inclined manner toward the rear.

図７、図１１に示すように、窓サッシの下枠１６は、前側に向かって緩やかに下向き傾斜状の上辺１６０と、水平状の下辺１６１と、上辺１６０と下辺１６１の前側部位を連結する垂直辺１６２と、上辺１６０の先端（垂直辺１６２よりも屋外側に位置する）に形成した上側被係止片１６００と、下辺１６１の先端（垂直辺１６２よりも屋外側に位置する）に形成した下側被係止片１６１０と、を備えている。垂直辺１６２は、螺子Ｓ３が固定される被固定部であり、垂直辺１６２には、下枠６側の挿通孔６８に対応して、螺子Ｓ３が螺入される部位（1つの態様では、螺子孔を備えていないが、予め螺子孔を備えていてもよい）を備えている。 As shown in FIGS. 7 and 11, the lower frame 16 of the window sash connects the upper side 160 gently inclined downward toward the front side, the lower side 161 horizontally, and the front side portions of the upper side 160 and the lower side 161. Formed on the vertical side 162, the upper locked piece 1600 formed at the tip of the upper side 160 (located on the outdoor side of the vertical side 162), and the tip of the lower side 161 (located on the outdoor side of the vertical side 162). The lower locked piece 1610 and the like are provided. The vertical side 162 is a fixed portion to which the screw S3 is fixed, and the vertical side 162 is a portion into which the screw S3 is screwed corresponding to the insertion hole 68 on the lower frame 6 side (in one embodiment, It does not have a screw hole, but it may have a screw hole in advance).

下枠６の上側装着片６６の上側係止片６６０及び下側装着片６７の下側係止片６７０を窓サッシの下枠１６の被係止部１６００、１６１０にそれぞれ係止させた状態で螺子Ｓ３によって、下枠６の後端側部位を窓サッシの下枠１６に固定する。図１１に示すように、ガイド片６９は、予め定められた角度に螺子Ｓ３の軸部の進入角度を規制するような角度で延びており、螺子Ｓ３が取り付けられた状態で、螺子Ｓ３の軸部とガイド片６９は近接平行ないし当接している。また、ガイド片６９は、下枠６を窓サッシの下枠１６に連結した状態で、下枠１６（被固定部としての垂直辺１６２）に接触しないような寸法を有している。 In a state where the upper locking piece 660 of the upper mounting piece 66 of the lower frame 6 and the lower locking piece 670 of the lower mounting piece 67 are locked to the locked portions 1600 and 1610 of the lower frame 16 of the window sash, respectively. The rear end side portion of the lower frame 6 is fixed to the lower frame 16 of the window sash by the screw S3. As shown in FIG. 11, the guide piece 69 extends at a predetermined angle at an angle that regulates the approach angle of the shaft portion of the screw S3, and the shaft of the screw S3 is attached with the screw S3 attached. The portion and the guide piece 69 are in close parallel or in contact with each other. Further, the guide piece 69 has dimensions so as not to come into contact with the lower frame 16 (vertical side 162 as a fixed portion) in a state where the lower frame 6 is connected to the lower frame 16 of the window sash.

従来、下枠６を躯体（窓サッシの下枠１６等）に螺子で固定する際に、螺子の角度が定まり難く、取付作業の作業性が悪くなっていた。本実施形態では、下枠固定螺子（螺子Ｓ３）の挿通孔６８に近接してガイド片６９を設けて螺子Ｓ３の角度を規制することで、螺子Ｓ３の角度を定まり易くしている。こうすることで、螺子Ｓ３が打ち易くなり、打ち損じも低減する。また、下枠６が固定された状態で、ガイド片６９は躯体（窓サッシの下枠１６）と非接触状態にあるため、挿通孔６８から侵入した雨水が躯体へ伝達することを可及的に防止している。 Conventionally, when the lower frame 6 is fixed to the frame (lower frame 16 of the window sash, etc.) with screws, the angle of the screws is difficult to determine, and the workability of the mounting work is deteriorated. In the present embodiment, the guide piece 69 is provided in the vicinity of the insertion hole 68 of the lower frame fixing screw (screw S3) to regulate the angle of the screw S3, so that the angle of the screw S3 can be easily determined. By doing so, the screw S3 can be easily hit and the hitting failure can be reduced. Further, since the guide piece 69 is in a non-contact state with the skeleton (lower frame 16 of the window sash) with the lower frame 6 fixed, it is possible that rainwater invading from the insertion hole 68 is transmitted to the skeleton. It is prevented.

下枠６が窓サッシの下枠１６に固定された状態で、下枠６の下面（下辺６４）は、窓サッシの下枠の下面（下辺１６１）よりも僅かに上方に位置している。図１７に示す従来例では、下枠６´の下面が窓サッシの下枠１６´の下面よりも下方に位置しており、納まりに制限があった。また、サッシ下の防水シート貼りやシーリング等の作業がし難くなっていた。本実施形態では、下枠６の下面を窓サッシの下枠１６の下面よりも上方に位置させたことで（下枠６の下面と窓サッシの下枠１６の下面を同じ高さ位置としてもよい）、納まりのバリエーションが拡大し、サッシ下の防水シート貼りやシーリング等の作業性が向上する。 With the lower frame 6 fixed to the lower frame 16 of the window sash, the lower surface (lower side 64) of the lower frame 6 is located slightly above the lower surface (lower side 161) of the lower frame of the window sash. In the conventional example shown in FIG. 17, the lower surface of the lower frame 6'is located below the lower surface of the lower frame 16' of the window sash, and there is a limitation in fitting. In addition, it was difficult to attach a tarpaulin under the sash and perform sealing. In the present embodiment, the lower surface of the lower frame 6 is positioned above the lower surface of the lower frame 16 of the window sash (even if the lower surface of the lower frame 6 and the lower surface of the lower frame 16 of the window sash are positioned at the same height). Good), the variation of fitting is expanded, and the workability such as attaching a waterproof sheet under the sash and sealing is improved.

図１４に示すように、連結部材８は、概ね方形状の水平板状部８０と、水平板状部８０の第１辺から垂直に立ち上がる第１垂直板状部８１と、水平板状部８０の第２辺（第１辺に隣接する辺であり、第１辺に対して直角に延びる辺）から垂直に立ち上がる第２垂直板状部８２と、からなり、第１垂直板状部８１と第２垂直板状部８２は平面視において互いに直角に延びている。図示の態様では、第１辺は長辺であり、第２辺が短辺である。水平板状部８０には、連結部材８を下枠６に固定するための螺子Ｓ４の挿通孔として例示する長孔８００が形成されている。第１垂直板状部８１、第２垂直板状部８２の上側部位には、連結部材８をガイドレール下地枠２に固定するリベットＲを装着するための孔８１０、８２０がそれぞれ形成されている。図示の態様では、第１垂直板状部８１と第２垂直板状部８２は独立して水平板状部８０から立ち上がっているが、第１垂直板状部８１と第２垂直板状部８２の近接する端部同士を垂直部材（図示せず）を介して連結（例えば溶接）することで、強度を増してもよい。 As shown in FIG. 14, the connecting member 8 includes a substantially square horizontal plate-shaped portion 80, a first vertical plate-shaped portion 81 rising vertically from the first side of the horizontal plate-shaped portion 80, and a horizontal plate-shaped portion 80. A second vertical plate-shaped portion 82 rising vertically from the second side (a side adjacent to the first side and extending at a right angle to the first side), and a first vertical plate-shaped portion 81. The second vertical plate-shaped portion 82 extends at right angles to each other in a plan view. In the illustrated embodiment, the first side is the long side and the second side is the short side. The horizontal plate-shaped portion 80 is formed with an elongated hole 800 exemplified as an insertion hole for a screw S4 for fixing the connecting member 8 to the lower frame 6. Holes 810 and 820 for mounting the rivet R for fixing the connecting member 8 to the guide rail base frame 2 are formed in the upper portions of the first vertical plate-shaped portion 81 and the second vertical plate-shaped portion 82, respectively. .. In the illustrated embodiment, the first vertical plate-shaped portion 81 and the second vertical plate-shaped portion 82 independently rise from the horizontal plate-shaped portion 80, but the first vertical plate-shaped portion 81 and the second vertical plate-shaped portion 82 The strength may be increased by connecting (for example, welding) the adjacent ends of the above to each other via a vertical member (not shown).

図１２、図１３を参照しつつ、ガイドレール下地枠２と連結部材８との固定構成について説明する。連結部材８は、水平板状部８０の下面をガイドレール下地枠２の下端に一致ないし近接させ、第１垂直板状部８１をガイドレール下地枠２の第１見込辺２１の内面（開口部から遠い側の面）に当接させ、第２垂直板状部８２をガイドレール下地枠２の屋内側見付片２０（第１部分２００）の屋外側面に当接させて、第１垂直板状部８１と第１見込辺２１、第２垂直板状部８２と屋内側見付辺２０を、それぞれ、固定手段として例示するリベットＲで固定する。ガイドレール下地枠２に固定された連結部材８において、第１垂直板状部８１は、見込方向ないし屋内外方向に延び、第２垂直板状部８２は、見付方向に延びている。すなわち、連結部材８は、２つの部位（第１垂直板状部８１と第２垂直板状部８２）において、ガイドレール下地枠２の２つの面（第１見込辺２１、屋内側見付辺２０）に固定されており、本実施形態では、前記２つの面は、異なる方向（第１見込辺２１は見込方向、屋内側見付辺２０は見付方向）に延びている。第１垂直板状部８１とガイドレール下地枠２の第１見込辺２１を固定するリベットＲの軸心線と第２垂直板状部８２とガイドレール下地枠２の屋内側見付辺２０を固定するリベットＲの軸心線は平面視において直交する。 A fixed configuration of the guide rail base frame 2 and the connecting member 8 will be described with reference to FIGS. 12 and 13. In the connecting member 8, the lower surface of the horizontal plate-shaped portion 80 coincides with or is close to the lower end of the guide rail base frame 2, and the first vertical plate-shaped portion 81 is placed on the inner surface (opening portion) of the first prospective side 21 of the guide rail base frame 2. The second vertical plate-shaped portion 82 is brought into contact with the outdoor side surface of the indoor side finding piece 20 (first portion 200) of the guide rail base frame 2 so as to be in contact with the surface on the side far from the first vertical plate. The shaped portion 81 and the first prospective side 21, the second vertical plate-shaped portion 82 and the indoor side finding side 20 are fixed by rivets R exemplified as fixing means, respectively. In the connecting member 8 fixed to the guide rail base frame 2, the first vertical plate-shaped portion 81 extends in the prospective direction or the indoor / outdoor direction, and the second vertical plate-shaped portion 82 extends in the finding direction. That is, the connecting member 8 has two surfaces (first prospective side 21, indoor side found side) of the guide rail base frame 2 in two portions (first vertical plate-shaped portion 81 and second vertical plate-shaped portion 82). It is fixed to 20), and in the present embodiment, the two surfaces extend in different directions (the first prospective side 21 is the prospective direction, and the indoor side found side 20 is the founding direction). The axial core line of the rivet R that fixes the first prospective side 21 of the first vertical plate-shaped portion 81 and the guide rail base frame 2, the second vertical plate-shaped portion 82, and the indoor side found side 20 of the guide rail base frame 2 The axial core lines of the fixed rivets R are orthogonal to each other in a plan view.

連結部材８の水平板状部８０は、下枠６の上辺６０に近接対向して延びており、連結部材８の水平板状部８０は、固定手段として例示する螺子Ｓ４によって下枠６に固定される。螺子Ｓ４は、略垂直方向に延び、連結部材８の水平板状部８０の長孔８００、下枠６の上辺６０の孔６０１を貫通し、下枠６の中空部内の幅方向両端部位に設けた被連結部材９に固定されている。 The horizontal plate-shaped portion 80 of the connecting member 8 extends in close proximity to the upper side 60 of the lower frame 6, and the horizontal plate-shaped portion 80 of the connecting member 8 is fixed to the lower frame 6 by a screw S4 exemplified as a fixing means.

The connected member 9 has an L-shaped side view from the hanging side 91 that hangs down along the lower portion of the vertical side 61, and the connected member 9 uses a rivet R to make the upper surface 90 into the upper side 60 (rivet R) of the lower frame 6. It is fixed to the lower frame 6 by being connected to the fixing hole 602). The connected member 9 functions as a reinforcing member, and is made of a metal material having a melting point higher than that of the aluminum mold material forming the lower frame 6 and having a high strength against heat, for example, a steel steel plate. The elongated hole 800 of the horizontal plate-shaped portion 80 of the connecting member 8 is aligned with the screw hole 900 of the upper surface portion 90 of the connected member 9 and fixed with the screw S4. The shaft portion of the screw S4 is located in the hollow portion of the lower frame 6. It is also possible to provide the connected member outside the hollow portion of the lower frame 6 on the lower surface of the lower side 64 and fix it with a screw, but in the present embodiment, the connected member 9 is exposed to the outside of the lower frame 6. Since there is no such thing, it is not necessary to match the color of the aluminum material of the lower frame 6 in consideration of the appearance design, and the horizontal plate-shaped portion 80 of the connecting member 8 and the upper surface portion of the connected member 9 are sandwiched between the lower side 60. Since 90 is located, workability when tightening the screw S4 is good. When the connected member 9 is inserted into the hollow portion of the lower frame 6, the cross-sectional shape of the connected member 9 is set along the cross-sectional shape of the hollow portion of the lower frame 6 so as to reduce the play or rattling of the connected member 9. The shape is easy to fix the screw S4 to the connected member 9. In the illustrated embodiment, the upper surface portion 90 of the connected member 9 extends along the lower surface of the upper side 60 of the lower frame 6, and the hanging side 91 extends along the lower portion of the indoor vertical side 61 of the lower frame 6. However, the shape of the connected member 9 is not limited to that shown in the figure, and for example, a hanging side (shown) that hangs down from the indoor side end of the upper surface portion 90 along the rear side 65 of the lower frame 6. It may be provided with a U-shaped side view.

図１３に示すように、下枠６の開口幅方向の両端部には、キャップ１７が固定されている。キャップ１７は、下枠６の中空部の端部に挿入する挿入部を備えており、リベットＲによって、挿入部を下枠６の上辺６０（リベットＲの固定用の孔６０３）に連結することで、下枠６に固定されている。 As shown in FIG. 13, caps 17 are fixed to both ends of the lower frame 6 in the opening width direction. The cap 17 is provided with an insertion portion to be inserted into the end of the hollow portion of the lower frame 6, and the insertion portion is connected to the upper side 60 of the lower frame 6 (hole 603 for fixing the rivet R) by the rivet R. It is fixed to the lower frame 6.

本実施形態では、下枠６は、ガイドレール下地枠２の下端部位および窓サッシの下枠１６に連結されている。下枠６の屋内側部位は、当該屋内側部位を窓サッシの下枠１６に対して支持する第１支持手段と、当該屋内側部位をガイドレール下地枠２に対して支持する第２支持手段とによって持ち出し状に支持されている。下枠６とガイドレール下地枠２の連結部位（螺子Ｓ４によって固定される部位）、すなわち第２支持手段は、下枠６の後端側の支持手段（上側装着片６６、下側装着片６７、螺子Ｓ３）、すなわち第１支持手段よりも屋外側に位置している。本実施形態では、屋外側に持ち出し状に支持されている下枠６は、複数箇所においてシャッター側縦枠（ガイドレール下地枠２）の下方部位に固定された連結部材８を介して当該シャッター側縦枠に連結されており、下枠６は連結部材８によって複数箇所でシャッター側縦枠に支持ないし吊持されることになり、下枠６の屋外側部位が下方に垂れるように変形ないし回動する力に連結部材８が対抗することができ、下枠６に補強板材を設けることなく、火災時の熱による下枠の熱変形（例えば、熱変形して屋外側・下方に垂れるように倒れること）を可及的に防止する。シャッター側縦枠（ガイドレール下地枠２）は連結部材８によって複数面において下枠６に固定されているので、シャッター側縦枠を補強することによって当該縦枠に作用する力に対抗することができ、防火上不利やシャッター側縦枠（ガイドレール下地枠２）の開きや傾きの発生を防止する。 In the present embodiment, the lower frame 6 is connected to the lower end portion of the guide rail base frame 2 and the lower frame 16 of the window sash. The indoor side portion of the lower frame 6 is a first support means for supporting the indoor side portion with respect to the lower frame 16 of the window sash, and a second support means for supporting the indoor side portion with respect to the guide rail base frame 2. It is supported by a carry-out. The connecting portion between the lower frame 6 and the guide rail base frame 2 (the portion fixed by the screw S4), that is, the second supporting means is the supporting means on the rear end side of the lower frame 6 (upper mounting piece 66, lower mounting piece 67). , Screw S3), that is, located on the outdoor side of the first support means. In the present embodiment, the lower frame 6 supported on the outdoor side in a carry-out shape is on the shutter side via a connecting member 8 fixed to a lower portion of the shutter side vertical frame (guide rail base frame 2) at a plurality of locations. The lower frame 6 is connected to the vertical frame, and the lower frame 6 is supported or suspended by the shutter side vertical frame at a plurality of places by the connecting member 8, and the lower frame 6 is deformed or rotated so as to hang downward. The connecting member 8 can oppose the moving force, and the lower frame is thermally deformed by the heat of a fire (for example, it is thermally deformed and hangs down on the outdoor side / downward side) without providing a reinforcing plate material on the lower frame 6. To prevent falling down as much as possible. Since the shutter side vertical frame (guide rail base frame 2) is fixed to the lower frame 6 on a plurality of surfaces by the connecting member 8, it is possible to counter the force acting on the vertical frame by reinforcing the shutter side vertical frame. This can prevent the disadvantage of fire prevention and the opening and tilting of the vertical frame on the shutter side (guide rail base frame 2).
