[Operation of this embodiment]
Hereinafter, the operation of the raising / lowering window 1 according to the present embodiment will be described. For example, when a fire occurs on the outdoor side, it is as follows.
During a fire on the outdoor side, the raising / lowering window 1 gradually rises in temperature upon receiving radiant heat from the outdoor side.
Each of the heat-expandable materials 71 to 80 and 91 expands as shown in FIG. 6 when reaching the expansion temperature (about 150 ° C.). In addition, the cross-sectional position shown in FIG.

  The expansion of the heating expansion materials 71 and 72 fills the space between the eaves cover material 61, the outdoor finding piece portion 321 and the extending piece portion 121A. At this time, the eaves cover member 61 is heated from the outdoor side and is slightly loosened with respect to the screw 6, so that it is easily bent and deformed. For this reason, the eaves cover material 61 is bent and deformed so as to expand to the outdoor side by the expanding thermal expansion materials 71 and 72. Thereby, the wall thickness of the expanded thermal expansion materials 71 and 72 increases.

  The resin attachment 63 is softened when it reaches the expansion temperature of each of the heat expansion materials 71 to 80, 91 or a predetermined softening temperature lower thereby, and the resin attachment 63 and the frame cover material 62 are easily disengaged. Become. In this state, the heating expansion material 80 expands downward and press-contacts the resin attachment 63, thereby applying a force in a direction away from the frame prospective piece portion 122 side to the frame cover member 62. Due to this force, the frame cover member 62 is released from the frame prospective piece portion 122 by being disengaged from the resin attachment 63.

The heating expansion material 73 expands upward at substantially the same timing as the heating expansion material 80, and covers the outdoor side of the heel cover material 61 while assisting the removal of the frame cover material 62. Since the resin attachment 63 is softened, the resin attachment 63 is easily detached from the screw 7 due to the expansion of the heat expansion material 73 and falls off the frame prospective piece 122.
In this way, the expansion of the heating expansion materials 71, 72, 73 expands the outside of the lower sliding piece 39 by heat.

Further, the soot hollow portion 326 is filled by the expansion of the heating expansion material 74, and the groove portion 120 is filled by the expansion of the heating expansion material 75 to 77. Thereby, the upper part, the lower part, and the indoor side of the lower sliding piece 39 are thermally shielded.
Further, the frame hollow portion 127 is filled by the expansion of the heating expansion materials 78 and 79. Thereby, for example, a flame or the like is prevented from entering the frame hollow portion 127 from the drain port (not shown) of the hanging piece portion 123.

  In addition, each expansion | swelling place in the upper frame 11, the vertical frame 13, the upper eaves 21,31, the lower eaves 22,32, and the vertical eaves 23,33 is thermally interrupted by expansion | swelling of each heating expansion material 91.

[Effect of this embodiment]
(1) A heel cover material 61 that covers the lower heel 32 and the outdoor side of the groove forming portion 121 is provided, and the heat expansion materials 71 and 72 are disposed between the heel cover material 61 and the lower heel 32 and the groove forming portion 121. Therefore, the expansion of the heating expansion materials 71 and 72 at the time of a fire can fill the space between the cover material 61 and the lower rod 32 and the groove forming portion 121, and cut off the heat conduction from the outdoor side to the lower sliding piece 39. it can.
In addition, since the firewood cover material 61 is attached to the lower firewood 32, and the heating expansion material 73 is disposed on the outer surface side of the firewood cover material 61 on the window opening 5 side surface of the frame prospective piece portion 122, in the event of a fire In this case, the heated expansion material 73 expands without being hindered by the attachment portion of the heel cover material 61, and the expansion can efficiently cover the outdoor side of the heel cover material 61. From the outdoor side to the lower sliding piece 39 The heat conduction can be effectively blocked.
In addition, since the frame cover member 62 located on the outdoor side of the saddle cover member 61 is attached to the frame prospective piece portion 122 via the resin attachment 63, the resin attachment is required until the heating expansion material 73 reaches the expansion temperature in the event of a fire. Since the frame cover material 62 is easily detached due to the softening of the 63, it can be quickly removed by the expansion of the heat expansion material 73. For this reason, the expansion of the heating expansion material 73 is not hindered by the frame cover material 62.
In addition, since the heat expansion materials 71 and 72 are disposed between the heel cover material 61 and the lower heel 32 and the groove forming portion 121, the heat expansion materials 71 and 72 can be protected from the outdoor side by the heel cover material 61. In addition, since the heel cover material 61 covers the lower heel 32 and the outdoor side of the groove forming portion 121, the heating expansion materials 71 and 72, the lower heel 32 and the groove forming portion 121 can be hidden from the outdoor side. Moreover, by covering the heating expansion material 73 with the frame cover material 62, the heating expansion material 73 can be protected from the outdoor side and can be blinded.
