<<< About Heated Foam 70 >>>
In the present embodiment, as shown in FIGS. 5 and 6, the heating foam material 70 is attached to both the above-described slide member frame facing surface 53 and the above-described vertical region surface 60. (It may be fixed with a fixing tool such as a screw). The heated foam 70 expands when exposed to a flame during a fire, and its volume increases. And by this, a clearance can be filled and the path of a flame can be blocked.

  Conventionally, the heating foam material 70 has not been provided on the slide member frame facing surface 53. Therefore, in the event of a fire, the flame is opposed to the slide member frame facing surface 53 of the slide member 52 provided on the frame facing surface facing the vertical frame 13 of the door 20 and the door frame 21 of the frame 10. There has been a problem that it easily passes through the gap between the inner side surface 14 and the inner side surface 14.

  Furthermore, due to the fact that thermal expansion along the vertical direction occurs in the slide member 52 in the event of a fire, the glemon pin 54 located at the narrow portion of the glemon receiver 56 moves to the wide portion and engages. There was an event that would come off. In such a case, the restraint of the door 20 on the frame body 10 is released, and there is a problem in that a fire through hole is formed.

  On the other hand, in the present embodiment, since the heating foam material 70 is provided on the slide member frame facing surface 53, the flame passes through the gap between the slide member frame facing surface 53 and the inner side surface 14 in the event of a fire. It is possible to appropriately suppress problems that occur.

  Further, since the heating foam material 70 is provided on the region surface 60 where the vertical sliding member is not located, the heating foam material 70 expands toward the inner side surface 14 of the frame 10 in the event of a fire. Therefore, the expanded heating foam 70 can block the thermal expansion of the slide member 52 in the vertical direction. Therefore, disengagement of the glemon pin 54 is avoided, and the problem of forming a fire through hole can be appropriately suppressed.

  Further, in the present embodiment, as shown in FIGS. 5 and 6, the heating foam material 70 is formed on both the region surface 60 a where the upper slide member is not located and the region surface 60 b where the lower slide member is not located. It was decided to provide. Therefore, in the event of a fire, the flame between the upper and lower region surfaces 60a, 60b and the inner side surface 14 is flamed at both the upper and lower positions of the door frame 21 and the vertical frame 13 facing the door frame 21. Can be appropriately suppressed.

  In this embodiment, as shown in FIGS. 5 and 6, the slide member is divided into six parts so as to avoid physical interference with the latch housing part 43 that houses the gremon pin 54, the latch 42, and the like. A heating foam material 70 is affixed to the frame facing surface 53. Moreover, the heating foam material 70 is affixed on each of the upper region surface 60a and the lower region surface 60b.

  As shown in FIG. 4, the vertical region surface 60 includes a vertical first region surface 60 c that is hidden or exposed behind the slide member 52 by a sliding operation of the slide member 52, and a slide member. 52, the second region surface 60d in the vertical direction that is always exposed regardless of the sliding operation of 52 is provided. In the present embodiment, of the first region surface 60c and the second region surface 60d, The heating foam material 70 is provided only on the second region surface 60d. The heating foam material 70 may be provided on the entire second region surface 60d, or may be provided on a part of the second region surface 60d.

  In addition, the heating foam material 70 has a rectangular shape in which the long side direction is along the vertical direction in plan view. Further, the length of the heating foam material 70 in the short side direction (that is, the width of the heating foam material 70) substantially matches the width of the slide member frame facing surface 53 and the region surface 60 (length in the prospective direction). .
