可動框体55の可動框本体551の上の見込面には、トップラッチ56を構成するトップラッチ本体561が固定されており、トップラッチ56を操作する操作部561aが屋内側見付壁551aを貫通して屋内側から操作可能に配置されている。 The top latch main body 561 constituting the top latch 56 is fixed to the prospective surface on the movable stile main body 551 of the movable stile body 55, and the operation unit 561a for operating the top latch 56 attaches the indoor side finding wall 551a. It penetrates and is arranged so that it can be operated from the indoor side.

図1,図2に示すように、換気框ユニット5は、見込壁511の2条の嵌合片511a,511bが内障子2の上框21のガラス間口21a内に挿入され、左、右竪フレーム53,54の2条の嵌合片531a,531b,541a,541bが内障子2の左、右竪框23,24のガラス間口23a,24aに挿入されて、内障子2の上方位置に配置されており、換気框ユニット5のガラス間口51aと左、右竪框23,24及び下框22の内周に複層ガラス等のパネルが装着されて内障子2を構成している。 As shown in FIGS. 1 and 2, in the ventilation stile unit 5, the two fitting pieces 511a and 511b of the prospect wall 511 are inserted into the glass frontage 21a of the upper stile 21 of the shoji sash 2, and the left and right vertical columns are used. The two fitting pieces 531a, 531b, 541a, 541b of the frames 53 and 54 are inserted into the glass frontages 23a and 24a of the left and right stiles 23 and 24 of the sash 2 and placed above the sash 2. Panels such as double glazing are attached to the glass frontage 51a of the ventilation stile unit 5 and the inner circumferences of the left and right stiles 23 and 24 and the lower stile 22 to form the internal shoji 2.

そして、内障子2に装着された可動框体55は、図3(a)に示す閉鎖状態から、操作部561aを上方に回動してトップラッチ56を解除したうえで屋内側にひくことで、図3(b)に示す開放状態とすることができる。 Then, the movable stile 55 attached to the shoji 2 is pulled indoors after releasing the top latch 56 by rotating the operation unit 561a upward from the closed state shown in FIG. 3A. , The open state shown in FIG. 3 (b) can be obtained.

以上の建具においては、内障子2の框材のガラス間口を利用して換気框ユニット5を装着することで、障子に対して簡単に換気装置を組み込むことができる。
しかし、障子の框材の内周に換気框ユニットを組み込むことで、火災時には、換気框ユニットの気密材などが溶融するなどして隙間が生じたりして、防火性能が劣化する可能性があった。
In the above fittings, the ventilation stile unit 5 can be easily incorporated into the sash by using the glass frontage of the stile material of the sash 2.
However, by incorporating the ventilation stile unit on the inner circumference of the stile material of the shoji, in the event of a fire, the airtight material of the ventilation stile unit may melt and create gaps, resulting in deterioration of fire protection performance. rice field.

例えば、火災時には、図7(a)に示すように、換気框ユニット5の上フレーム51に取付けられている屋外側の気密材s1及び屋内側の気密材s2が溶融することで、上フレーム51と可動框体55との間に屋内外に連通する連通路L1が発生する可能性があるが、特に、上フレーム51と可動框体55との間にはトップラッチ56が配置されていることから、連通路L1を確実に閉塞することは、難しかった。 For example, in the event of a fire, as shown in FIG. 7A, the airtight material s1 on the outdoor side and the airtight material s2 on the indoor side, which are attached to the upper frame 51 of the ventilation frame unit 5, are melted to melt the upper frame 51. There is a possibility that a communication passage L1 communicating indoors and outdoors may occur between the movable frame 55 and the movable frame 55, but in particular, a top latch 56 is arranged between the upper frame 51 and the movable frame 55. Therefore, it was difficult to reliably block the communication passage L1.

本実施形態の建具は、火災時に、換気框ユニット5の各フレームと可動框体55との間に発生する隙間を塞ぐために、加熱膨張材fを適切に配置したものである。
以下、具体的に説明する。
In the fitting of the present embodiment, the thermal expansion material f is appropriately arranged in order to close the gap generated between each frame of the ventilation frame unit 5 and the movable frame 55 in the event of a fire.
Hereinafter, a specific description will be given.

本実施形態の建具の換気框ユニット5は、火災時に生じる換気框ユニット5の上フレーム51と可動框体55の上部との間の隙間を塞ぐために、図5,6に示すように、上フレーム51もしくは可動框体55に、第1加熱膨張材f1ないし第4加熱膨張材f4が配置されている。 The ventilation stile unit 5 of the fittings of the present embodiment has an upper frame as shown in FIGS. The first heating and expanding material f1 to the fourth heating and expanding material f4 are arranged on the 51 or the movable frame 55.

第1加熱膨張材f1は、可動框体55の可動框本体551の上見込面の左右両端部間において、長手方向に沿って設けられており、トップラッチ本体561が固定されている中央部位については、省かれている。 The first thermal expansion material f1 is provided along the longitudinal direction between the left and right ends of the upper prospective surface of the movable frame body 55 of the movable frame body 55, and the central portion to which the top latch body 561 is fixed. Is omitted.

第2加熱膨張材f2は、可動框体55の可動框本体551の上見込面の左右(見付)方向で中央部分において、トップラッチ本体561の両側に長手方向に沿って設けられており、トップラッチ本体561が干渉する中央部分については、省かれている。 The second thermal expansion material f2 is provided along the longitudinal direction on both sides of the top latch main body 561 at the central portion in the left-right (finding) direction of the upper prospective surface of the movable stile body 55 of the movable stile body 55. The central portion where the top latch body 561 interferes is omitted.

第3加熱膨張材f3は、上フレーム51の屋外側見付壁513の屋内側面の上方位置に設けられており、上フレーム51の見込壁511に固定されたトップラッチ受け562に対向するように、トップラッチ受け562が設けられている部分を含む中央範囲に設けられている。 The third heat expansion material f3 is provided at a position above the indoor side surface of the outdoor side finding wall 513 of the upper frame 51 so as to face the top latch receiver 562 fixed to the prospective wall 511 of the upper frame 51. , Is provided in the central range including the portion where the top latch receiver 562 is provided.

第4加熱膨張材f4は、可動框体55の屋内側見付壁551aの屋外側面に設けられており、可動框体55の上見込面に固定されたトップラッチ本体561に対向するように、トップラッチ本体561が設けられている部分を含む中央範囲に設けられている。なお、操作部561aが貫通する部分については、省かれている。 The fourth thermal expansion material f4 is provided on the outdoor side surface of the indoor side finding wall 551a of the movable frame 55 so as to face the top latch main body 561 fixed to the upper prospect surface of the movable frame 55. It is provided in the central range including the portion where the top latch main body 561 is provided. The portion through which the operation unit 561a penetrates is omitted.

したがって、火災が発生した際には、図7(b)にしめすように、上フレーム51と可動框体55の上部との間に配置された加熱発泡材f1〜加熱発泡材f4が発泡する。 Therefore, when a fire breaks out, the heated foaming material f1 to the heated foaming material f4 arranged between the upper frame 51 and the upper part of the movable frame 55 foams as shown in FIG. 7B.

そして、さらに火災が進み、上フレーム51と可動框体55の上部との間を気密している気密材s1,s2が溶融しても、図7(c)に示すように、加熱発泡材f1〜加熱発泡材f4が十分に発泡して、上フレーム51と可動框体55の上部との間に充満するので、屋内外の連通を抑制することができる。 Then, even if the fire further progresses and the airtight materials s1 and s2 that are airtight between the upper frame 51 and the upper part of the movable frame 55 melt, as shown in FIG. 7C, the heated foaming material f1 -Since the heated foaming material f4 is sufficiently foamed and fills between the upper frame 51 and the upper part of the movable frame 55, communication between indoors and outdoors can be suppressed.

具体的には、可動框体55の左右両端部間の長手方向に沿って設けられる第1加熱膨張材f1を、可動框体55の屋内側上見込面に設けることで、上フレーム51の下面に設けられた上戸当壁部512に対向させることができるので、発泡した第1加熱膨張材f1が素早く上戸当壁部512に到達して、上フレーム51と可動框体55との間に隙間が生じることを抑制することができる。 Specifically, the lower surface of the upper frame 51 is provided by providing the first thermal expansion material f1 provided along the longitudinal direction between the left and right ends of the movable frame 55 on the indoor side upper prospect surface of the movable frame 55. Since it can face the upper door wall portion 512 provided in the above, the foamed first thermal expansion material f1 quickly reaches the upper door wall portion 512, and a gap is provided between the upper frame 51 and the movable frame 55. Can be suppressed from occurring.

そして、第1加熱膨張材f1を配置することのできないトップラッチ56が固定された中央部分においては、可動框体55の屋内側見付壁551aの屋外側面に設けられた加熱膨張材f4が屋内側からトップラッチ56に向けて膨張する換気框ユニット5の全長に亘って閉塞することができる。 Then, in the central portion where the top latch 56 on which the first heating / expanding material f1 cannot be arranged is fixed, the heating / expanding material f4 provided on the outdoor side surface of the indoor side finding wall 551a of the movable frame 55 is used. It can be closed over the entire length of the ventilation stile unit 5 that expands from the inside toward the top latch 56.

また、火災時には熱によって上フレーム51及び可動框体55が反るなど変形した際に、両者の変形具合の違いで上フレーム51及び可動框体55の左右方向で中央付近に隙間が生じやすいが、可動框体55の屋外側上見込面に設けられた第2加熱膨張材f2が膨張することで中央付近に隙間が生じることを抑制し、さらに、第2加熱膨張材f2を配置することのできないトップラッチ56が干渉する部分についても、上フレーム51の屋外側見付壁513の屋内側面に設けられた加熱膨張材f3が屋外側からトップラッチ56に向けて膨張することで閉塞することができ、トップラッチ56が配置された複雑な空間における屋内外の連通を確実に閉塞することができる。 Further, in the event of a fire, when the upper frame 51 and the movable frame 55 are deformed due to heat such as warping, a gap is likely to occur near the center in the left-right direction of the upper frame 51 and the movable frame 55 due to the difference in the degree of deformation between the two. , It is possible to suppress the formation of a gap near the center due to the expansion of the second heating expansion material f2 provided on the outdoor side upper prospective surface of the movable frame 55, and further to arrange the second heating expansion material f2. Even in the portion where the top latch 56 interferes, the heat expansion material f3 provided on the indoor side surface of the outdoor side finding wall 513 of the upper frame 51 may be blocked by expanding from the outdoor side toward the top latch 56. It is possible to reliably block the indoor / outdoor communication in the complicated space where the top latch 56 is arranged.

なお、本実施形態の建具の換気框ユニット5は、上記加熱膨張材f1〜f4以外にも、加熱膨張材を配置してもよい。 In the ventilation stile unit 5 of the fitting of the present embodiment, a heating expansion material may be arranged in addition to the heating expansion materials f1 to f4.

例えば、本実施形態の建具の換気框ユニット5は、火災時に生じる換気框ユニット5の下フレーム52と可動框体55の下部との間の隙間を塞ぐために、下フレーム52の下戸当壁部522の屋外側面に第5加熱膨張材f5が配置されている。 For example, the ventilation stile unit 5 of the fitting of the present embodiment closes the gap between the lower frame 52 of the ventilation stile unit 5 and the lower part of the movable stile 55 that occurs in the event of a fire. A fifth heat-expanding material f5 is arranged on the outdoor side surface of the above.

したがって、火災が発生した際には、図7(b)にしめすように、下フレーム52と可動框体55の下部との間で加熱発泡材f5が発泡し、さらに火災が進み、下フレーム52と可動框体55の下部との間を気密している気密材sが溶融しても、図7(c)に示すように、下フレーム52と可動框体55の下部との間に充満するので、屋内外の連通を抑制することができる。 Therefore, when a fire breaks out, as shown in FIG. 7B, the heated foam material f5 foams between the lower frame 52 and the lower part of the movable frame 55, and the fire further progresses, and the lower frame 52 Even if the airtight material s, which is airtight between the movable frame 55 and the lower part of the movable frame 55, melts, the space between the lower frame 52 and the lower part of the movable frame 55 is filled as shown in FIG. 7 (c). Therefore, communication between indoors and outdoors can be suppressed.

さらに、本実施形態の建具は、換気框ユニット5の左、右竪フレーム53,54と可動框体55の左右側面との間の隙間を塞ぐために、左、右竪フレーム53,54の見込壁531,541の内周面に第6加熱膨張材f6が配置されている。 Further, in the fitting of the present embodiment, in order to close the gap between the left and right vertical frames 53 and 54 of the ventilation frame unit 5 and the left and right side surfaces of the movable frame 55, the prospective walls of the left and right vertical frames 53 and 54 are closed. The sixth heating and expanding material f6 is arranged on the inner peripheral surface of 531,541.

第6加熱膨張材f6が膨張することで、左、右竪フレーム53,54と可動框体55の側面との間を気密している気密材s,sが溶融しても、加熱発泡材f6が発泡して、左、右竪フレーム53,54と可動框体55の側面との間に充満するので、屋内外の連通を抑制することができる。 Even if the airtight materials s and s that are airtight between the left and right vertical frames 53 and 54 and the side surfaces of the movable frame 55 are melted by the expansion of the sixth heat expansion material f6, the heat foam material f6 Foams and fills between the left and right vertical frames 53 and 54 and the side surfaces of the movable frame 55, so that communication between indoors and outdoors can be suppressed.

また、本実施形態の建具は、換気框ユニット5の上フレーム51の屋外側上面に長手方向に沿って加熱膨張材f7が配置されており、火災時に膨張して、障子の上框21の変形と換気框ユニット5の変形具合が異なることで生じる上框21と換気框ユニット5の間の隙間を塞ぐことができる。 Further, in the fitting of the present embodiment, the heating expansion material f7 is arranged along the longitudinal direction on the outdoor side upper surface of the upper frame 51 of the ventilation frame unit 5, and expands in the event of a fire to deform the upper frame 21 of the shoji. It is possible to close the gap between the upper stile 21 and the ventilation stile unit 5 caused by the different deformations of the ventilation stile unit 5 and the ventilation stile unit 5.

また、本実施形態の建具は、換気框ユニット5の下フレーム52の中空部に排水経路が形成されており、排水経路の排水口が形成されている部分に加熱膨張材f8が配置されており、火災時に膨張して、換気框ユニット5の排水経路を塞ぐことができる。 Further, in the fitting of the present embodiment, a drainage path is formed in the hollow portion of the lower frame 52 of the ventilation frame unit 5, and the heat expansion material f8 is arranged in the portion where the drainage port of the drainage path is formed. , It can expand in the event of a fire and block the drainage path of the ventilation stile unit 5.

また、本実施形態の建具は、換気框ユニット5の下フレーム52のガラス間口52aの屋内側に長手方向に沿って加熱膨張材f9が配置されており、火災時に膨張して、ガラス間口52aに生じる隙間を塞ぐことができる。 Further, in the fitting of the present embodiment, the heat expansion material f9 is arranged along the longitudinal direction on the indoor side of the glass frontage 52a of the lower frame 52 of the ventilation frame unit 5, and expands in the event of a fire to reach the glass frontage 52a. The resulting gap can be closed.

以上のように、本実施形態の建具においては、トップラッチを備えた換気装置が配置されている建具において、火災時に換気装置に発生する連通路を確実に閉塞することができるので、換気装置の気密材を必要以上に耐火仕様にすることなく、防火性能を向上させることができる。 As described above, in the fittings of the present embodiment, in the fittings in which the ventilation device provided with the top latch is arranged, the communication passage generated in the ventilation device in the event of a fire can be reliably blocked. Fire protection performance can be improved without making the airtight material more fire resistant than necessary.

特に、換気装置において、トップラッチ56が配置される上フレーム61と可動框体55の間隙は、火災時には、上フレーム51の屋外側見付壁513と可動框体55の屋内側見付壁551aによって形成される空間を複数の方向から膨張する加熱膨張材によって充満させることとなるので、より確実に隙間の発生を防ぐことができる。 In particular, in the ventilation system, the gap between the upper frame 61 on which the top latch 56 is arranged and the movable frame 55 is such that in the event of a fire, the outdoor side finding wall 513 of the upper frame 51 and the indoor side finding wall 551a of the movable frame 55 Since the space formed by the above is filled with the heat-expanding material that expands from a plurality of directions, it is possible to more reliably prevent the generation of gaps.

また、本実施形態の建具においては、上フレーム51の屋外側見付壁513と可動框体55の屋内側見付壁551aによって形成される空間は、屋内側の見込面に配置される第1加熱膨張材f1と屋内側見付面に配置される第4加熱膨張材f4によって屋内側の防火構造が構成され、屋外側の見込面に配置される第2加熱膨張材f2と屋外側見付面に配置される第3加熱膨張材f4によって屋外側の防火構造を構成している。 Further, in the fitting of the present embodiment, the space formed by the outdoor side finding wall 513 of the upper frame 51 and the indoor side finding wall 551a of the movable frame 55 is arranged on the indoor side prospective surface. A fireproof structure on the indoor side is formed by the heating expansion material f1 and the fourth heating expansion material f4 arranged on the indoor side finding surface, and the second heating expanding material f2 arranged on the outdoor side prospective surface and the outdoor side finding surface. The fireproof structure on the outdoor side is formed by the third heating and expanding material f4 arranged on the surface.

そのため、屋内側で火災が発生した場合には、上フレーム51と可動框体55は屋内側に向かって中央が膨らむように反り、両者の変形具合の相違によって上フレーム51と可動框体55の屋内側見付壁551aとの間の中央付近に隙間が生じやすいが、該隙間を第1加熱膨張材f1と第4加熱膨張材f4によって比較的早期に塞ぐことができる。 Therefore, when a fire breaks out on the indoor side, the upper frame 51 and the movable frame 55 warp so that the center bulges toward the indoor side, and the upper frame 51 and the movable frame 55 are deformed due to the difference in the degree of deformation between the upper frame 51 and the movable frame 55. A gap is likely to occur near the center between the indoor side finding wall 551a, but the gap can be closed relatively early by the first heating expansion material f1 and the fourth heating expansion material f4.

また、屋外側で火災が発生した場合には、上フレーム51と可動框体55は屋外側に向かって中央が膨らむように反り、両者の変形具合の相違によって上フレーム51の屋外側見付壁513と可動框体55の間の中央付近に隙間が生じやすいが、該隙間を第2加熱膨張材f2と第3加熱膨張材f3によって比較的早期に塞ぐことができる。 Further, when a fire breaks out on the outdoor side, the upper frame 51 and the movable frame 55 warp so that the center bulges toward the outdoor side, and the outdoor side finding wall of the upper frame 51 due to the difference in the degree of deformation between the two. A gap is likely to occur near the center between the 513 and the movable frame 55, but the gap can be closed relatively early by the second heating expansion material f2 and the third heating expansion material f3.

なお、換気框ユニット5に配置される各加熱膨張材の幅や長さは、適宜変更してもよい。
例えば、可動框体55の屋外側上面に配置される第2加熱膨張材f2は、トップラッチ56の両側の中央部分のみではなく、トップラッチ56部分を除く左右両端部間全長に設けてもよい。
The width and length of each thermal expansion material arranged in the ventilation stile unit 5 may be appropriately changed.
For example, the second thermal expansion material f2 arranged on the outdoor side upper surface of the movable frame 55 may be provided not only in the central portion on both sides of the top latch 56 but also in the entire length between the left and right end portions excluding the top latch 56 portion. ..

また、本発明は、実施形態の換気框ユニット5に配置された加熱膨張材のすべてを備えていなくてもよい。例えば、上フレーム51と可動框体55との間の空間について、屋内側の防火構造を構成する屋内側見込面に配置される第1加熱膨張材f1と屋内側見付面に配置される第4加熱膨張材f4のみを配置したものでもよく、屋外側見込面に配置される第2加熱膨張材f2と屋外側見付面に配置される第3加熱膨張材f4のみを配置したものでもよい。 Further, the present invention does not have to include all of the thermal expansion materials arranged in the ventilation stile unit 5 of the embodiment. For example, regarding the space between the upper frame 51 and the movable frame 55, the first heat expansion material f1 arranged on the indoor side prospective surface constituting the indoor fireproof structure and the indoor side finding surface are arranged. 4 Only the heating / expanding material f4 may be arranged, or only the second heating / expanding material f2 arranged on the outdoor side prospective surface and the third heating / expanding material f4 arranged on the outdoor side finding surface may be arranged. ..

以上の実施形態は,請求項に記載された発明を限定するものではなく,例示として取り扱われることは言うまでもない。 It goes without saying that the above embodiments do not limit the invention described in the claims and are treated as examples.
