<Operation to open the surface grid 6 by the upper bracket 12>
According to the upper bracket 12 having the above-described configuration, by having the resin screw 60 having a configuration different from that of the lower bracket 10, different operations can be performed as described below. The operation will be described with reference to FIGS. 14 and 15.

14 and 15 are cross-sectional views and side views for explaining an operation in which the resin screw 60 is melted and the surface grid 6 is opened.

As shown in FIG. 14, a fire occurs inside the building having the sash 2, and the heat causes the resin screw 60 to melt (indicated by a dotted line in FIG. 14A). The configuration of the upper bracket 12 other than the resin screw 60 is made of SUS and has heat resistance, and does not melt at the temperature at which the resin screw 60 melts (for example, around 200 ° C.).

When the resin screw 60 melts, the connection between the third bracket 54 and the back plate 56 is released. As a result, the back plate 56 moves downward by gravity together with the front plate 80 connected to the back plate 56 (see arrow D1). Since the front plate 80 is urged downward by the urging member 84, it can be moved downward more reliably. Further, since the long hole 90 is formed in the second arm 82B connected to the front plate 80 and the shaft member 88 is inserted therein, the second arm 82B can move downward together with the front plate 80, and the back side can be moved downward. The downward movement of the plate 56 and the front plate 80 can be further promoted.

When the connection between the third bracket 54 and the back plate 56 is completely disconnected, the surface grid 6 moves away from the upper bracket 12 and the sash 2 as shown in FIG. When the second arm 82B of the arm member 82 rotates with respect to the first arm 82A in the rotation direction P about the shaft member 88, the upper portion of the surface grid 6 moves outward. Since the resin screw is not used in the lower bracket 10 described above, the surface grid 6 is not fixed by the lower bracket 10, and the surface grid 6 is released only by the upper bracket 12. In the lower bracket 10, the surface grid 6 is rotated by rotating the third bracket 18 shown in FIGS. 4 and 5 with the rotation axis 19 as the center of rotation. As a result, the surface grid 6 can be rotated so that the upper side of the surface grid 6 is opened. By such an operation, the closed area by the surface grid 6 can be released, the heat 100 inside the building having the sash 2 can be released upward, and the safety can be improved.

As described above, the upper bracket 12 of the present embodiment has a first bracket 50 as a sash side bracket fixed to the sash 2 and a face grid side connected to the first bracket 50 and fixed to the face grid 6. A third bracket 54 as a bracket is provided. The upper bracket 12 is further made of a thermoplastic resin and includes a resin screw 60 for fixing the third bracket 54 to the surface grid 6.

According to such a configuration, when a fire occurs in the building to which the surface grid 6 is attached, the resin screw 60 is melted by heat, so that the fixing of the third bracket 54 and the surface grid 6 is released, and the surface grid 6 is released. It becomes possible to move in the direction away from the sash. By automatically moving the surface grid 6 to open the space in the event of a fire, the heat inside the building can be released to the outside, and safety can be improved. As described above, even when the mounting structure 8 is mounted on the sash 2, it is possible to prevent the sash 2 from being adversely affected by fire protection, and the flame shielding performance of the sash 2 can be maintained.

Further, the upper bracket 12 of the present embodiment further includes a front plate 80, a back plate 56, and an arm member 82. The front plate 80 is arranged outside the vertical groove 58 formed along the vertical direction D of the surface grid 6. The back plate 56 is connected to the front plate 80 and is arranged inside the vertical groove 58 of the surface grid 6, and the resin screw 60 penetrating the third bracket 54 is screwed into the back plate 56. The arm member 82 has a first arm 82A and a second arm 82B attached so as to be relatively rotatable, the first arm 82A is attached to the first bracket 50, and the second arm 82B is attached to the front plate 80. Has been done.

According to such a configuration, when the resin screw 60 is melted, the fixing of the third bracket 54 and the back plate 56 is released, so that the back plate 56 and the front plate 80 are vertically separated from the fixed portion by the surface grid 6. It becomes movable along the groove 58. Further, since the front plate 80 and the first bracket 50 are connected by the arm member 82, the arm member 82 can be rotated so as to open by moving the front plate 80, and the angle at which the surface grid 6 opens can be set to the arm. It can be controlled by the member 82.

Further, the upper bracket 12 of the present embodiment is further attached between the surface grid 6 and the front plate 80 at a position below the front plate 80, and urges the surface grid 6 and the front plate 80 to come close to each other. The urging member 84 is provided.

According to such a configuration, the front plate 80 can be reliably moved downward when the resin screw 60 is melted, and the rotation of the arm member 82 can be promoted.

Further, according to the upper bracket 12 of the present embodiment, the second arm 82B has an elongated hole 90 formed along the longitudinal direction in which the second arm 82B extends. Further, the first arm 82A has a shaft member 88 that is inserted into the elongated hole 90 of the second arm 82B and can move along the elongated hole 90. The first arm 82A and the second arm 82B are relatively rotatably attached around the shaft member 88 of the first arm 82A.

According to such a configuration, the first arm 82A with respect to the second arm 82B within the range in which the shaft member 88 of the first arm 82A moves through the elongated hole 90 of the second arm 82B when the resin screw 60 is melted. It becomes relatively movable. This makes it possible to promote the movement of the front plate 80 and the back plate 56 when the resin screw 60 is melted.

Further, according to the upper bracket 12 of the present embodiment, the melting point of the thermoplastic resin constituting the resin screw 60 is 180 ° C. or higher and 220 ° C. or lower.
