Description

本発明の一態様にかかる防火面格子では、前記窓枠側ブラケットを、下板部と縦板部とからなり、略L字形状を有する、持ち出し板部を備えるものとすることができる。
また、前記下板部を、屋外側端部の下部に備えられた屋外側開口係合凹部と、屋外側端部の上部に備えられた屋内側開口係合凹部と、上端縁に備えられた屋外側に向かうほど下側に向かう方向に傾斜し、かつ、屋外側の端部が前記屋内側開口係合凹部につながった傾斜案内部と、該傾斜案内部の屋内側の端部に備えられた上側開口保持凹部とを有するものとすることができる。
また、前記面格子側ブラケットを、屋外側部に備えられ、かつ、前記屋外側開口係合凹部と係合可能な屋外側枢軸と、屋内側端部に備えられ、かつ、前記屋内側開口係合凹部及び前記上側開口保持凹部のそれぞれと係合可能な屋内側枢軸とを有するものとすることができる。
前記面格子本体の閉鎖状態では、前記屋外側枢軸を前記屋外側開口係合凹部に対して係合させ、かつ、前記屋内側枢軸を前記上側開口保持凹部に対して係合させる。
前記解除機構が作動した際には、前記屋外側枢軸を前記面格子本体の揺動中心として、前記面格子本体の揺動動作を開始させる。
そして、前記面格子本体の揺動動作が進行する(開放角度が大きくなる)と、前記面格子本体の自重によって、前記屋外側枢軸を前記屋外側開口係合凹部から屋外側に抜け出させると同時に、前記屋内側枢軸を前記上側開口保持凹部から上側に抜け出させて前記傾斜案内部に対して係合させる。
そして、前記屋内側枢軸が前記屋内側開口係合凹部に対して係合するまで、前記屋内側枢軸を前記傾斜案内部に沿って屋外側へ摺動させることで、前記面格子本体を屋外側へとスライド移動させる。
なお、前記屋内側枢軸が前記屋内側開口係合凹部に係合した時点における前記面格子本体の姿勢次第で、前記面格子本体は、前記屋内側枢軸を揺動中心としてさらに揺動する。
In a fire grille according to one aspect of the present invention, the window frame side bracket can be provided with a protruding plate portion consisting of a lower plate portion and a vertical plate portion and having a generally L-shape.
The lower plate portion can have an outdoor opening engagement recess provided at the bottom of the outdoor end, an indoor opening engagement recess provided at the top of the outdoor end, an inclined guide portion provided at the upper edge which slopes downward as it approaches the outdoor side and whose outdoor end is connected to the indoor opening engagement recess, and an upper opening retaining recess provided at the indoor end of the inclined guide portion.
In addition, the grille side bracket can have an outdoor side pivot provided on the outdoor side and engageable with the outdoor side opening engagement recess, and an indoor side pivot provided at the indoor side end and engageable with each of the indoor side opening engagement recess and the upper opening retaining recess.
When the grille body is in a closed state, the outdoor pivot shaft engages with the outdoor opening engagement recess, and the indoor pivot shaft engages with the upper opening retention recess.
When the release mechanism is activated, the outdoor pivot shaft becomes the swing center of the grille body, and the grille body starts to swing.
Then, as the swinging motion of the grille body progresses (the opening angle becomes larger), the weight of the grille body causes the outdoor side pivot to slip out of the outdoor side opening engagement recess to the outdoor side, and at the same time, the indoor side pivot to slip out upward from the upper opening retaining recess and engage with the inclined guide portion.
Then, the indoor side pivot shaft is slid toward the outdoor side along the inclined guide portion until the indoor side pivot shaft engages with the indoor side opening engagement recess, thereby sliding the grille body toward the outdoor side.
Depending on the attitude of the grille body at the time when the indoor side pivot shaft engages with the indoor side opening engagement recess, the grille body may further swing around the indoor side pivot shaft as the swing center.

《網戸》
網戸19は、図2及び図3に示すように、屋外側枠体24の屋内側に取り付けられており、屋外側枠体24の開口部を塞いでいる。なお、本例の構造においては、網戸19の清掃や交換などのメンテナンス作業は、室内側から行うことが可能である。
Screen door
2 and 3, the screen door 19 is attached to the indoor side of the outdoor side frame body 24 and closes the opening of the outdoor side frame body 24. In the structure of this example, maintenance work such as cleaning and replacement of the screen door 19 can be performed from the indoor side.

付勢部材59は、ロック装置16により面格子本体14を閉鎖位置にロックした状態では、台座部58の屋外側面と、面格子本体14を構成する左右の縦框本体34a、34b(縦框閉塞片35a、35bの屋外側板部)の屋内側面との間で圧縮されている。 When the grille main body 14 is locked in the closed position by the locking device 16, the biasing member 59 is compressed between the outdoor side of the base portion 58 and the indoor side of the left and right vertical frame main bodies 34a, 34b ( the outdoor side panel portions of the vertical frame blocking pieces 35a, 35b) that constitute the grille main body 14.

また、窓枠側ロック部材51に備えられた係合孔57の中心軸と、面格子側ロック部材52に備えられた係合ピン62の中心軸とを、上下方向に向けて配置し、かつ、解除機構63による係合ピン62の可動方向を、中心軸の方向と一致する下向きとしているため、ロック装置16の屋内外方向の寸法を小さくできる。このため、防火面格子1の屋外側への張出量を抑えることができる。 In addition, the central axis of the engagement hole 57 in the window frame locking member 51 and the central axis of the engagement pin 62 in the grille locking member 52 are arranged in the vertical direction, and the direction in which the engagement pin 62 is moved by the release mechanism 63 is downward, which coincides with the direction of the central axis, so that the size of the locking device 16 in the indoor/outdoor direction can be reduced. This makes it possible to reduce the amount by which the fire grille 1 protrudes outdoors.

ケーシング本体64aは、面内方向両側に配置された1対の側板部79と、1対の側板部79の屋内側の端部同士をつなぐ前板部80とを有する。1対の側板部79の互いに対向する内側面には、屋内側係止溝81と屋外側係止溝82とが、上下方向の全長にわたり備えられている。前板部80の上下方向中間部には、上下方向に長い長孔であるガイド孔83が備えられている。ガイド孔83の面内方向に関する幅寸法は、係合ピン62aを構成する後述の軸部84の外径よりもわずかに大きく、ガイド孔83の上下方向の長さ寸法は、係合ピン62aを構成する軸部84の外径よりも十分に大きい。ケーシング本体64aの内側には、係合ピン62aの屋外側部分及び解除機構63aが収容されている。 The casing body 64a has a pair of side plate parts 79 arranged on both sides in the in-plane direction, and a front plate part 80 connecting the indoor end parts of the pair of side plate parts 79. An indoor side locking groove 81 and an outdoor side locking groove 82 are provided on the inner surfaces facing each other in the vertical direction over the entire length. A guide hole 83, which is a long hole that is long in the vertical direction, is provided in the vertical middle part of the front plate part 80. The width dimension of the guide hole 83 in the in-plane direction is slightly larger than the outer diameter of a shaft part 84 (described later) that constitutes the engagement pin 62a, and the length dimension of the guide hole 83 in the vertical direction is sufficiently larger than the outer diameter of the shaft part 84 that constitutes the engagement pin 62a. The outdoor side part of the engagement pin 62a and the release mechanism 63a are housed inside the casing body 64a.

可動板87は、矩形板状に構成されており、ケーシング本体64aに備えられた屋内側係止溝81の内側に配置されている。可動板87の下部には、上向き凸状の下側係止部89が備えられている。可動板87の上端部は、融解部材73aを介して、ケーシング本体64aに固定されている。このため、可動板87は、融解部材73aが溶断する以前の状態では、ケーシング本体64aに対する相対変位が不能であるが、火災発生時に、融解部材73aが溶断すると、ケーシング本体64aに対する相対変位が可能になる。具体的には、可動板87は、屋内側係止溝81に沿って下方への移動が可能になる。 The movable plate 87 is configured in a rectangular plate shape and is disposed inside the indoor side locking groove 81 provided in the casing body 64a. The lower part of the movable plate 87 is provided with an upwardly protruding lower locking portion 89. The upper end of the movable plate 87 is fixed to the casing body 64a via the melting member 73a. Therefore, the movable plate 87 cannot be displaced relative to the casing body 64a before the melting member 73a melts, but when the melting member 73a melts in the event of a fire, the movable plate 87 becomes capable of being displaced relative to the casing body 64a. Specifically, the movable plate 87 becomes capable of moving downward along the indoor side locking groove 81 .
