本実施形態では、ガラス外れ止め部材４０ａとガラス外れ止め部材４０ｂは、同じ形状のガラス外れ止め部材４０である。次に、このガラス外れ止め部材４０の構成について説明する。図６は、本実施形態のガラス外れ止め部材４０の分解斜視図である。 In the present embodiment, the glass retaining member 40a and the glass retaining member 40b are glass retaining members 40 having the same shape. Next, the configuration of the glass retaining member 40 will be described. FIG. 6 is an exploded perspective view of the glass retaining member 40 of the present embodiment.

図６に示すように、本実施形態のガラス外れ止め部材４０は、框体３０に固定される保持金具４１と、保持金具４１によって保持される押さえ片４２と、を備える。本実施形態では、保持金具４１及び押さえ片４２は、何れも金属製（例えば、ステンレス鋼）である。 As shown in FIG. 6, the glass retaining member 40 of the present embodiment includes a holding metal fitting 41 fixed to the frame 30 and a holding piece 42 held by the holding metal fitting 41. In the present embodiment, the holding metal fitting 41 and the holding piece 42 are both made of metal (for example, stainless steel).

保持金具４１は、框体３０との間に隙間を形成する台部４１ａと、台部４１ａの両側（見込方向に直交する）に配置される取付部４１ｂと、を備える。両側の取付部４１ｂのそれぞれには、見込方向に細長い締結孔４１ｃが形成される。この締結孔４１ｃに締結部材としてのネジ４５が締結されることにより、保持金具４１が框体３０に固定される。台部４１ａは、固定された状態で框体３０の見込面との間に隙間を形成する。台部４１ａの室内側の端部には、室内側から室外側に切り欠かれた係合孔４１ｄが形成される。また、台部４１ａの室内側の端部には、ガラス２５側に向かって延出する延出片４１ｅが形成される。延出片４１ｅは、係合孔４１ｄを跨る壁状に形成されており、保持金具４１に係合された状態の押さえ片４２に対向する。 The holding metal fitting 41 includes a base portion 41a that forms a gap between the holding metal fitting 41 and the frame body 30, and mounting portions 41b that are arranged on both sides (orthogonal in the prospective direction) of the base portion 41a. Fastening holes 41c elongated in the prospective direction are formed in each of the mounting portions 41b on both sides. By fastening the screw 45 as a fastening member to the fastening hole 41c, the holding metal fitting 41 is fixed to the frame 30. The base portion 41a forms a gap between the base portion 41a and the prospective surface of the frame 30 in a fixed state. At the end of the base 41a on the indoor side, an engagement hole 41d cut out from the indoor side to the outdoor side is formed. Further, at the end portion of the base portion 41a on the indoor side, an extension piece 41e extending toward the glass 25 side is formed. The extending piece 41e is formed in a wall shape straddling the engaging hole 41d, and faces the holding piece 42 in a state of being engaged with the holding metal fitting 41.

押さえ片４２は、ガラス２５の端部に対向する押さえ部４２ａと、押さえ部４２ａの下部から室内側に延びる係合部４２ｂと、押さえ部４２ａの下部で係合部４２ｂの両側にそれぞれ延びる足部４２ｃと、を備える。押さえ片４２の係合部４２ｂが保持金具４１の係合孔４１ｄに係合することで押さえ片４２が保持金具４１に係合固定される。本実施形態の係合部４２ｂは、その先端がガラス２５側に突出する爪状に形成されており、台部４１ａの裏側を通って爪状の部分が係合孔４１ｄの端面に係合する。 The holding piece 42 has a holding portion 42a facing the end of the glass 25, an engaging portion 42b extending inward from the lower portion of the holding portion 42a, and a foot extending on both sides of the engaging portion 42b at the lower portion of the holding portion 42a. A portion 42c and the like are provided. The holding piece 42 is engaged and fixed to the holding metal fitting 41 by engaging the engaging portion 42b of the holding piece 42 with the engaging hole 41d of the holding metal fitting 41. The engaging portion 42b of the present embodiment is formed in a claw shape whose tip protrudes toward the glass 25, and the claw-shaped portion passes through the back side of the base portion 41a and engages with the end surface of the engaging hole 41d. ..

本実施形態では、押さえ片４２は、保持金具４１に係合した状態でも見込方向で若干の移動が可能となっている。保持金具４１と押さえ片４２の係合を解除する場合は、係合部４２ｂの爪状の部分を框体３０側に押し込んで係合を解除し、押さえ片４２を室内外側に移動させる。 In the present embodiment, the holding piece 42 can be slightly moved in the prospective direction even when it is engaged with the holding metal fitting 41. When disengaging the holding metal fitting 41 and the holding piece 42, the claw-shaped portion of the engaging portion 42b is pushed toward the frame 30 to disengage the engaging piece 42, and the holding piece 42 is moved indoors and outdoors.

框体３０に固定されたガラス外れ止め部材４０の取付状態について説明する。まず、吊元側縦框（縦框）３３に固定されるガラス外れ止め部材４０ａについて説明する。図７は、本実施形態の建具１に適用されるガラス外れ止め部材４０ａ及びその周囲を示す拡大横断面図である。 The mounting state of the glass retaining member 40 fixed to the frame 30 will be described. First, the glass detachment preventing member 40a fixed to the hanging base side vertical stile (vertical stile) 33 will be described. FIG. 7 is an enlarged cross-sectional view showing the glass retaining member 40a applied to the fitting 1 of the present embodiment and its surroundings.

図７に示すように、ガラス外れ止め部材４０が吊元側縦框３３に固定された状態では、押さえ部４２ａが室外側ガラス２５ａの吊元側端部に室外側で対面した状態となる。ガラス外れ止め部材４０ａは、保持金具４１を框体３０に取り付けた状態で加熱発泡材３８を配置し、ガラス２５を嵌め込んだ状態で押さえ片４２を保持金具４１に係合させる。加熱発泡材３８は、ガラス２５の４周を囲う帯状に形成されており、ガラス外れ止め部材４０に差し掛かる部分では、保持金具４１の台部４１ａのガラス２５側の面に加熱発泡材３８が載った状態となる。加熱発泡材３８は、接着剤、接着テープ等を用いた接着固定やネジ等を用いた締結固定等、適宜の方法で框体３０に固定される。 As shown in FIG. 7, when the glass retaining member 40 is fixed to the hanging-side vertical frame 33, the holding portion 42a faces the hanging-side end of the outdoor glass 25a on the outdoor side. In the glass retaining member 40a, the heated foam material 38 is arranged with the holding metal fitting 41 attached to the frame 30, and the holding piece 42 is engaged with the holding metal fitting 41 with the glass 25 fitted. The heated foaming material 38 is formed in a band shape surrounding four circumferences of the glass 25, and the heated foaming material 38 is formed on the surface of the base portion 41a of the holding metal fitting 41 on the glass 25 side at a portion approaching the glass retaining member 40. It will be in the state of being placed. The heated foaming material 38 is fixed to the frame 30 by an appropriate method such as adhesive fixing using an adhesive, adhesive tape, etc., or fastening and fixing using screws or the like.

保持金具４１は、吊元側縦框３３の中空部３３ｂに配置される室外側縦框芯材３３ｅに締結孔４１ｃを通じてネジ４５が締結固定されることにより、吊元側縦框３３の見込面に固定される。上述のように、締結孔４１ｃは、見込方向に長い長孔となっている。従って、吊元側縦框３３及び室外側縦框芯材３３ｅに対する加工位置を変えることなく、保持金具４１の取付位置を見込方向（室内外方向）で調整することが可能となっている。例えば、室外側ガラス２５ａの室外側面から保持金具４１の延出片４１ｅまでの長さを距離ｄ１とすると、距離ｄ１は保持金具４１の取付位置によって変わることになる。押さえ片４２は保持金具４１によって位置が決まるので、ガラス２５と押さえ片４２の位置関係は保持金具４１の取付位置によって調整することができる。 The holding metal fitting 41 is fixed to the outdoor vertical frame core material 33e arranged in the hollow portion 33b of the hanging source side vertical frame 33 through the fastening hole 41c, so that the screw 45 is fastened and fixed to the prospective surface of the hanging source side vertical frame 33. Is fixed to. As described above, the fastening hole 41c is an elongated hole long in the prospective direction. Therefore, it is possible to adjust the mounting position of the holding metal fitting 41 in the prospective direction (indoor / outdoor direction) without changing the processing position with respect to the hanging source side vertical frame 33 and the outdoor vertical frame core material 33e. For example, assuming that the length from the outdoor surface of the outdoor glass 25a to the extension piece 41e of the holding metal fitting 41 is the distance d1, the distance d1 changes depending on the mounting position of the holding metal fitting 41. Since the position of the holding piece 42 is determined by the holding metal fitting 41, the positional relationship between the glass 25 and the holding piece 42 can be adjusted by the mounting position of the holding metal fitting 41.

なお、本実施形態では、押さえ片４２は、保持金具４１に係合された状態でも見込方向に若干移動可能となっているが、この移動範囲も保持金具４１の位置によって決まるので、何れにしても保持金具４１の取付位置によってガラス２５とガラス外れ止め部材４０ａの位置関係が調整されることになる。 In the present embodiment, the holding piece 42 can be slightly moved in the prospective direction even when it is engaged with the holding metal fitting 41, but this moving range is also determined by the position of the holding metal fitting 41. However, the positional relationship between the glass 25 and the glass retaining member 40a is adjusted depending on the mounting position of the holding metal fitting 41.

以上、図７を参照して吊元側縦框３３に固定されるガラス外れ止め部材４０ａについて説明したが、戸先側縦框３４でも同様の構成及び方法でガラス外れ止め部材４０ａが吊元側縦框３３と同様に距離ｄ１の設定で戸先側縦框３４に固定される。 Although the glass retaining member 40a fixed to the hanging base side vertical stile 33 has been described above with reference to FIG. 7, the glass retaining member 40a is also provided on the hanging source side by the same configuration and method in the door end side vertical stile 34. Similar to the vertical stile 33, it is fixed to the door end side vertical stile 34 by setting the distance d1.

次に、上框（横框）３１に固定されるガラス外れ止め部材４０ｂについて説明する。図８は、本実施形態の建具１に適用されるガラス外れ止め部材４０ｂ及びその周囲を示す拡大縦断面図である。 Next, the glass retaining member 40b fixed to the upper stile (horizontal stile) 31 will be described. FIG. 8 is an enlarged vertical sectional view showing the glass retaining member 40b applied to the fitting 1 of the present embodiment and its surroundings.

図８に示すように、ガラス外れ止め部材４０ｂが上框３１に固定された状態では、押さえ部４２ａが室外側ガラス２５ａの上端部に室外側で対面した状態となる。なお、ガラス外れ止め部材４０ｂを上框３１に固定する方法は、吊元側縦框３３に固定する場合と基本的に同様であるが、ガラス２５とガラス外れ部材４０ｂの位置関係は、ガラス２５とガラス外れ部材４０ａの位置関係とは異なるように、保持金具４１が固定される。本実施形態では、縦框（吊元側縦框３３及び戸先側縦框３４）に設定されるガラス２５に対するガラス外れ止め部材４０の位置関係を示す距離ｄ１よりも、上框３１のガラス２５に対するガラス外れ止め部材４０の位置関係を示す距離ｄ２の方が長くなるように設定される。即ち、上框３１のガラス外れ止め部材４０は、縦框（吊元側縦框３３及び戸先側縦框３４）に比べて相対的に隙間が大きくなるようにレイアウトされる。 As shown in FIG. 8, when the glass retaining member 40b is fixed to the upper stile 31, the holding portion 42a faces the upper end portion of the outdoor glass 25a on the outdoor side. The method of fixing the glass detachment preventing member 40b to the upper stile 31 is basically the same as the case of fixing to the hanging source side vertical stile 33, but the positional relationship between the glass 25 and the glass detachment member 40b is the glass 25. The holding metal fitting 41 is fixed so as to be different from the positional relationship between the glass and the glass detaching member 40a. In the present embodiment, the glass 25 of the upper stile 31 is larger than the distance d1 indicating the positional relationship of the glass retaining member 40 with respect to the glass 25 set in the vertical stile (the vertical stile 33 on the hanging side and the vertical stile 34 on the door end side). The distance d2 indicating the positional relationship of the glass retaining member 40 with respect to the glass is set to be longer. That is, the glass retaining member 40 of the upper stile 31 is laid out so that the gap is relatively larger than that of the vertical stile (the vertical stile 33 on the hanging side and the vertical stile 34 on the door end side).

以上、図８を参照して上框３１に固定されるガラス外れ止め部材４０ｂについて説明したが、下框３２でも同様の構成及び方法でガラス外れ止め部材４０ｂが上框３１と同様に距離ｄ２の設定で下框３２に固定される。 Although the glass retaining member 40b fixed to the upper stile 31 has been described above with reference to FIG. 8, the glass retaining member 40b of the lower stile 32 has the same configuration and method as the upper stile 31 and has a distance d2. It is fixed to the lower stile 32 by setting.

以上説明した上記実施形態の構成によれば、以下のような効果を奏する。
建具１は框体３０を構成する吊元側縦框３３、戸先側縦框３４、上框３１及び下框３２のそれぞれに固定されるガラス外れ止め部材４０を備え、ガラス外れ止め部材４０は、ガラス２５の端部に見込方向一側で対面する押さえ片４２と、押さえ片を保持し、見込方向に長く形成される締結孔４１ｃを通じてネジ（締結部材）４５によって吊元側縦框３３、戸先側縦框３４、上框３１又は下框３２に固定される保持金具（保持部）４１と、を有する。 According to the configuration of the above-described embodiment described above, the following effects are obtained.
The fitting 1 includes a glass retaining member 40 fixed to each of the hanging side vertical stile 33, the door end side vertical stile 34, the upper stile 31 and the lower stile 32 constituting the stile body 30, and the glass retaining member 40 is provided. , The holding piece 42 facing the end of the glass 25 on one side in the prospective direction, and the hanging side vertical frame 33 by the screw (fastening member) 45 through the fastening hole 41c formed long in the prospective direction to hold the holding piece. It has a holding metal fitting (holding portion) 41 fixed to a vertical stile 34 on the door end side, an upper stile 31 or a lower stile 32.

これにより、加工位置を変えることなく保持金具４１の位置を調整することができる。また、火災発生時に樹脂製の框体３０が溶融してガラス２５が反ろうとしても締結孔４１ｃによって見込方向への押さえ片４２の移動が許容されるので、ガラス２５への応力の集中によるヒビや破損の発生を防止又は効果的に遅らせることができる。 As a result, the position of the holding metal fitting 41 can be adjusted without changing the processing position. Further, even if the resin frame 30 melts and the glass 25 tries to warp in the event of a fire, the fastening hole 41c allows the holding piece 42 to move in the prospective direction, so that cracks due to stress concentration on the glass 25 are allowed. Or damage can be prevented or effectively delayed.

また、本実施形態では、吊元側縦框３３及び戸先側縦框３４に固定されるガラス外れ止め部材ａと上框３１及び下框３２に固定されるガラス外れ止め部材４０ｂが、見込方向で位置をずらして配置される。 Further, in the present embodiment, the glass retaining member a fixed to the hanging base side vertical stile 33 and the door end side vertical stile 34 and the glass retaining member 40b fixed to the upper stile 31 and the lower stile 32 are in the expected direction. It is arranged by shifting the position with.

これにより、縦と横で異なるガラス２５の反りに応じてガラス外れ止め部材４０ａ，４０ｂの見込方向の位置をずらすことにより、框体３０の溶融時にガラス２５がガラス外れ止め部材４０ａ，４０ｂの応力による破損を効果的に防止できる。 As a result, the positions of the glass retaining members 40a and 40b in the prospective direction are shifted according to the warpage of the glass 25 which is different in the vertical and horizontal directions, so that the glass 25 is stressed by the glass retaining members 40a and 40b when the frame 30 is melted. Can effectively prevent damage caused by.

また、本実施形態では、長手方向が長い吊元側縦框３３及び戸先側縦框３４に固定されるガラス外れ止め部材４０ａの押さえ片４２とガラス２５の隙間よりも長手方向が短い上框３１及び下框３２に固定されるガラス外れ止め部材４０ｂの押さえ片４２とガラス２５の隙間の方が大きくなるように、見込方向で位置をずらして保持金具４１が吊元側縦框３３、戸先側縦框３４、上框３１及び下框３２のそれぞれに締結固定される。 Further, in the present embodiment, the upper stile whose longitudinal direction is shorter than the gap between the holding piece 42 of the glass retaining member 40a fixed to the hanging source side vertical stile 33 and the door end side vertical stile 34 which are long in the longitudinal direction and the glass 25. The holding metal fitting 41 is displaced in the prospective direction so that the gap between the holding piece 42 of the glass retaining member 40b fixed to the 31 and the lower stile 32 and the glass 25 is larger, and the holding metal fitting 41 is the hanging side vertical stile 33 and the door. It is fastened and fixed to each of the front vertical stile 34, the upper stile 31 and the lower stile 32.

これにより、長手方向が長いため反り易くなっているガラス２５を吊元側縦框３３及び戸先側縦框３４のガラス外れ止め部材４０ａによってしっかりと保持しつつ、火災発生時には相対的にガラス２５との間の隙間が大きい上框３１及び下框３２に配置されるガラス外れ止め部材４０ｂによって上下ではガラス２５の反りを許容することで応力の集中を防ぎ、ガラス２５の破損をより一層防止できる。 As a result, the glass 25, which is easily warped due to its long longitudinal direction, is firmly held by the glass detachment preventing member 40a of the hanging side vertical frame 33 and the door end side vertical frame 34, and the glass 25 is relatively held in the event of a fire. The glass retaining member 40b arranged on the upper stile 31 and the lower stile 32 having a large gap between the glass and the glass 25 allows the glass 25 to warp at the top and bottom, thereby preventing stress concentration and further preventing the glass 25 from being damaged. ..

上記実施形態の変形例について説明する。なお、以下の説明において上記実施形態と共通又は同様の構成については同じ符号を付してその説明を省略する場合がある。 A modified example of the above embodiment will be described. In the following description, the same reference numerals may be given to the configurations common to or similar to those of the above embodiment, and the description thereof may be omitted.

図９は、変形例のガラス外れ止め部材２４０の保持金具２４１を示す斜視図である。図９に示すように、保持金具２４１は、框体３０との間に隙間を形成する台部２４１ａと、台部２４１ａの両側に配置される取付部２４１ｂと、を備える。両側の取付部２４１ｂのそれぞれには、見込方向に細長い締結孔２４１ｃが形成される。この締結孔２４１ｃに締結部材としてのネジ４５が締結されることにより、保持金具２４１が框体３０に固定される。台部２４１ａは、固定された状態で框体３０の見込面との間に隙間を形成する。台部２４１ａの室内側の端部には、室内側から室外側に切り欠かれた係合孔２４１ｄが形成される。 FIG. 9 is a perspective view showing a holding metal fitting 241 of the glass retaining member 240 of the modified example. As shown in FIG. 9, the holding metal fitting 241 includes a base portion 241a forming a gap between the holding metal fitting 241 and the frame portion 30, and mounting portions 241b arranged on both sides of the base portion 241a. Fastening holes 241c elongated in the prospective direction are formed in each of the mounting portions 241b on both sides. By fastening the screw 45 as a fastening member to the fastening hole 241c, the holding metal fitting 241 is fixed to the frame 30. The base portion 241a forms a gap between the base portion 241a and the prospective surface of the frame 30 in a fixed state. At the end of the base portion 241a on the indoor side, an engagement hole 241d cut out from the indoor side to the outdoor side is formed.

図１０は、変形例の建具１に適用されるガラス外れ止め部材２４０ａ及びその周囲を示す拡大横断面図である。図１１は、変形例の建具に適用されるガラス外れ止め部材２４０ｂ及びその周囲を示す拡大縦断面図である。なお、図１０及び図１１に示す建具１は、ガラス外れ止め部材４０に関する構成以外は、上記実施形態と同様の構成である。 FIG. 10 is an enlarged cross-sectional view showing the glass retaining member 240a applied to the fitting 1 of the modified example and its surroundings. FIG. 11 is an enlarged vertical cross-sectional view showing the glass retaining member 240b applied to the fitting of the modified example and its surroundings. The fitting 1 shown in FIGS. 10 and 11 has the same configuration as that of the above embodiment except for the configuration relating to the glass retaining member 40.

図１０及び図１１に示すように、ガラス外れ止め部材２４０ａ，２４０ｂは、何れもＬ字状のプレート部材２４６を框体３０（上框３１、下框３２、吊元側縦框３３又は戸先側縦框３４）の見込面に配置し、このＬ字状のプレート部材２４６を介した状態で保持金具２４１がネジ４５によって框体３０に締結固定される。 As shown in FIGS. 10 and 11, the glass retaining members 240a and 240b each have an L-shaped plate member 246 as a frame 30 (upper frame 31, lower frame 32, hanging side vertical frame 33 or door end). It is arranged on the prospective surface of the side vertical frame 34), and the holding metal fitting 241 is fastened and fixed to the frame 30 by the screw 45 in a state of being interposed through the L-shaped plate member 246.

図１０に示すように、吊元側縦框３３の見込面に固定された保持金具２４の係合孔２４１ｄに押さえ片２４２が係合される。変形例の押さえ片２４２は、上記実施形態と同様の構成である。保持金具２４１は、上記実施形態の構成に比べて見込方向に直交する長手方向が長い形状となっており、押さえ片２４２も見込方向に直交する方向が長いものが用いられる。室外側ガラス２５ａの室外側面から保持金具２４１の室内側端部までの長さを距離ｄ３とすると、距離ｄ３は保持金具２４１の取付位置によって変わる。押さえ片２４２は保持金具２４１によって位置が決まるので、ガラス２５と押さえ片２４２の位置関係は保持金具２４１の取付位置によって調整することができる。戸先側縦框３４に固定されるガラス外れ止め部材２４０ａも同様の方法で取付位置が設定される。 As shown in FIG. 10, the holding piece 242 is engaged with the engaging hole 241d of the holding metal fitting 24 fixed to the prospective surface of the hanging side vertical frame 33. The holding piece 242 of the modified example has the same configuration as that of the above embodiment. The holding metal fitting 241 has a shape having a longer longitudinal direction orthogonal to the prospective direction as compared with the configuration of the above embodiment, and a holding piece 242 having a longer direction orthogonal to the prospective direction is used. Assuming that the length from the outdoor surface of the outdoor glass 25a to the indoor end of the holding metal fitting 241 is a distance d3, the distance d3 changes depending on the mounting position of the holding metal fitting 241. Since the position of the holding piece 242 is determined by the holding metal fitting 241, the positional relationship between the glass 25 and the holding piece 242 can be adjusted by the mounting position of the holding metal fitting 241. The mounting position of the glass retaining member 240a fixed to the door end side vertical frame 34 is set in the same manner.

図１１に示すように、上框３１の見込面に固定された保持金具２４の係合孔２４１ｄに押さえ片２４２が係合される。室外側ガラス２５ａの室外側面から保持金具２４１の室内側端部までの長さを距離ｄ４とすると、距離ｄ４も保持金具２４１の取付位置によって変わる。下框３２に固定されるガラス外れ止め部材２４０ａも同様の方法で取付位置が設定される。 As shown in FIG. 11, the holding piece 242 is engaged with the engaging hole 241d of the holding metal fitting 24 fixed to the prospective surface of the upper stile 31. Assuming that the length from the outdoor surface of the outdoor glass 25a to the indoor end of the holding metal fitting 241 is a distance d4, the distance d4 also changes depending on the mounting position of the holding metal fitting 241. The mounting position of the glass retaining member 240a fixed to the lower stile 32 is set in the same manner.

以上説明した本変形例においても、締結孔２４１ｃにより保持金具２４１の取付位置を見込方向で調整することができる。例えば、上記実施形態同様に距離ｄ３に対して距離ｄ４が長くなるようにガラス外れ止め部材２４０の取付位置を設定することができる。即ち、本変形例においても上記実施形態と同様の効果を奏する。 Also in the present modification described above, the mounting position of the holding metal fitting 241 can be adjusted in the prospective direction by the fastening hole 241c. For example, as in the above embodiment, the mounting position of the glass retaining member 240 can be set so that the distance d4 becomes longer with respect to the distance d3. That is, the same effect as that of the above-described embodiment is obtained in this modification.

上記実施形態及び変形例では、開閉可能な障子を備える建具として縦辷り窓を例に説明したが、横辷り窓や引違い窓のような開閉可能な障子を備える建具にも本発明を適用できる。また、ＦＩＸ窓のような框体の内側に窓を固定する建具に本発明を適用することができる。 In the above-described embodiments and modifications, a vertical sash window has been described as an example of a fitting having a sash that can be opened and closed. .. Further, the present invention can be applied to a fitting for fixing a window inside a frame such as a FIX window.

次に、図１２及び図１３を参照して上記変形例のガラス外れ止め部材２４０をＦＩＸ窓に適用した例について説明する。図１２は、本発明の一実施形態に係るＦＩＸ窓２０１に適用されるガラス外れ止め部材２４０及びその周囲を示す拡大横断面図である。図１３は、本発明の一実施形態に係るＦＩＸ窓２０１に適用されるガラス外れ止め部材２４０及びその周囲を示す拡大縦断面図である。 Next, an example in which the glass retaining member 240 of the above-mentioned modified example is applied to the FIX window will be described with reference to FIGS. 12 and 13. FIG. 12 is an enlarged cross-sectional view showing the glass retaining member 240 applied to the FIX window 201 according to the embodiment of the present invention and its surroundings. FIG. 13 is an enlarged vertical sectional view showing the glass retaining member 240 applied to the FIX window 201 according to the embodiment of the present invention and its surroundings.

なお、図１２及び図１３に示すＦＩＸ窓２０１は、上述の縦辷り窓の枠体１０と基本構造が同じものを框体とし、この枠体１０の内側にガラス２５を固定したものである。以下の説明では、吊元側縦枠１３を左右一側の縦枠１３とし、戸先側縦枠１４を左右他側の縦枠１４として説明する。 The FIX window 201 shown in FIGS. 12 and 13 has a frame body having the same basic structure as the frame body 10 of the above-mentioned vertical window, and the glass 25 is fixed inside the frame body 10. In the following description, the hanging source side vertical frame 13 will be referred to as a left and right vertical frame 13, and the door end side vertical frame 14 will be referred to as a left and right other side vertical frame 14.

枠体１０の室外側には、ガラス２５を押さえる樹脂製の押し縁部材１２７が嵌合固定される。また、枠体１０の室内側の見付面には、ガラス止め部材１２８が配置される。ガラス止め部材１２８は、見込方向でガラス２５を挟んで押し縁部材１２７の反対側に位置する。例えば、図１２では、左右一側に配置される縦枠１３に押し縁部材１２７及びガラス止め部材１２８が設けられる構成が示され、図１３では、下枠１２に押し縁部材１２７及びガラス止め部材１２８が設けられる構成が示される。 A resin ridge member 127 that presses the glass 25 is fitted and fixed to the outdoor side of the frame body 10. Further, a glass fixing member 128 is arranged on the finding surface on the indoor side of the frame body 10. The glass fixing member 128 is located on the opposite side of the push edge member 127 with the glass 25 sandwiched in the prospective direction. For example, FIG. 12 shows a configuration in which a push edge member 127 and a glass stopper member 128 are provided on a vertical frame 13 arranged on one side on the left and right sides, and FIG. 13 shows a configuration in which a push edge member 127 and a glass stopper member 128 are provided on a lower frame 12. The configuration in which 128 is provided is shown.

本変形例のＦＩＸ窓２０１は、枠体（框体）１０を構成する縦枠（縦框）１３，１４及び上枠（上框）１１、下枠（下框）１２のそれぞれに固定されるガラス外れ止め部材２４０を備え、ガラス外れ止め部材２４０は、ガラス２５の端部に見込方向一側で対面する押さえ片２４２と、押さえ片２４２を保持し、見込方向に長く形成される締結孔２４１ｃを通じてネジ４５によって縦枠１３，１４、上枠１１又は下枠１２に固定される保持金具２４１と、を有する。 The FIX window 201 of this modification is fixed to each of the vertical frames (vertical frames) 13, 14 and the upper frame (upper frame) 11 and the lower frame (lower frame) 12 constituting the frame body (frame body) 10. The glass retaining member 240 is provided, and the glass retaining member 240 holds the holding piece 242 facing the end of the glass 25 on one side in the prospective direction and the holding piece 242, and is formed long in the prospective direction. It has a holding metal fitting 241 fixed to a vertical frame 13, 14, an upper frame 11 or a lower frame 12 by a screw 45 through the glass 45.

本変形例のＦＩＸ窓２０１によっても、見込方向に長く形成される締結孔２４１ｃによって火災発生時に応力が集中してガラス２５が破損する事態の発生を防止できる。即ち、上記実施形態や変形例と同様の効果を奏する。 Also in the FIX window 201 of this modification, it is possible to prevent the occurrence of a situation where the glass 25 is damaged due to stress concentration at the time of a fire due to the fastening hole 241c formed long in the prospective direction. That is, the same effect as that of the above-described embodiment or modification is obtained.

このように、上記実施形態や変形例の構成に制限されるわけではなく、框体及びガラスを備える種々の建具に本発明を適用できる。また、ガラス外れ止め部材の構成も適宜変更することができる。例えば、室内外の両方に押さえ片を有する構成や室内側にのみ押さえ片を有する構成とすることも場合によっては可能である。 As described above, the present invention is not limited to the configurations of the above-described embodiments and modifications, and the present invention can be applied to various fittings including a frame and glass. In addition, the configuration of the glass retaining member can be changed as appropriate. For example, in some cases, it is possible to have a holding piece both indoors and outdoors, or to have a holding piece only on the indoor side.

上記実施形態では、長孔として形成される締結孔４１ｃ，２４１ｃを利用して保持金具４１，２４１の取付位置を見込方向でずらす例を説明したが、この構成に限定されない。例えば、上記実施形態の保持金具４１，２４１の締結孔４１ｃ，２４１ｃを長孔から丸孔に変更し、上框３１及び下框３２に対する保持金具４１のネジの締結位置と、吊元側縦框３３及び戸先側縦框３４に対する保持金具４１のネジの締結位置と、を見込方向でずらすことにより、ガラス２５に対する押さえ片４２の位置を調整する構成としてもよい。このように、框体３０に対する締結箇所が見込方向で異なるものの、吊元側縦框３３及び戸先側縦框３４に固定されるガラス外れ止め部材４０と、横框である上框３１又は下框３２に固定されるガラス外れ止め部材４０と、が見込方向で位置をずらして配置される建具を上記実施形態とは異なる方法で実現することもできる。 In the above embodiment, an example in which the mounting positions of the holding metal fittings 41 and 241 are shifted in the prospective direction by using the fastening holes 41c and 241c formed as the elongated holes has been described, but the present invention is not limited to this configuration. For example, the fastening holes 41c and 241c of the holding metal fittings 41 and 241 of the above embodiment are changed from long holes to round holes, and the screw fastening positions of the holding metal fittings 41 with respect to the upper stile 31 and the lower stile 32 and the hanging side vertical stile. The position of the holding piece 42 with respect to the glass 25 may be adjusted by shifting the screw fastening position of the holding metal fitting 41 with respect to the 33 and the door end side vertical frame 34 in the prospective direction. In this way, although the fastening points to the stile 30 differ depending on the expected direction, the glass retaining member 40 fixed to the hanging side vertical stile 33 and the door end side vertical stile 34, and the horizontal stile upper stile 31 or lower. It is also possible to realize a fitting in which the glass retaining member 40 fixed to the stile 32 and the fitting are arranged so as to be displaced in the prospective direction by a method different from the above-described embodiment.

また、上記実施形態で説明した上框３１、下框３２、吊元側縦框３３及び戸先側縦框３４の構成に限られず、框体の構成は適宜変更することができる。例えば、框体（上框、下框、吊元側縦框及び戸先側縦框）の見込方向室内側及び室外側の何れか一側又は両方にアルミ形材等の金属製のカバー部材を配置する構成としてもよい。 Further, the configuration is not limited to the upper stile 31, the lower stile 32, the hanging source side vertical stile 33, and the door end side vertical stile 34 described in the above embodiment, and the configuration of the stile body can be appropriately changed. For example, a metal cover member such as an aluminum profile is placed on either one or both of the indoor side and the outdoor side in the expected direction of the frame (upper frame, lower frame, hanging side vertical frame and door end side vertical frame). It may be configured to be arranged.
