In such a case, there is a problem that a passage (through hole) of a flame is generated by opening the door toe 56.

  On the other hand, in the present embodiment, the shoji opening prevention metal fitting 80 having the L-shaped section or the U-shaped cross section and having the overlapping portion A overlapping the vertical rail 37 in the prospective direction is attached to the engaging groove portion 60. Therefore, even if the shoji 40 (the door toe 56) is applied with a force pulled toward the heating surface, the shoji opening prevention metal fitting 80 hits the vertical rail 37 and is blocked. Therefore, the shoji opening prevention metal fitting 80 plays a role of preventing the shoji 40 (the door toe 56) from being opened in the event of a fire and causing the passage of a flame, so that when the fire occurs, It is possible to realize the sliding window 10 that can be prevented from being opened and causing a flame passage.

  In the present embodiment, a pulling piece 72 composed of an aluminum block 74 and a resin cover 76 is attached to the engaging groove 60, and the aluminum block 74 overlaps the vertical rail 37 in the prospective direction. It was decided to have an overlapping part.

  For this reason, not only the shoji opening prevention metal fitting 80 but also the attracting piece 72 has a function of preventing the door toe 56 from opening and causing a flame passage when the overlapping portion hits the vertical rail 37 in the event of a fire. It becomes possible to make it. Therefore, it is possible to more appropriately prevent the door toe 56 from opening when a fire occurs and causing a flame passage.

  In the present embodiment, the length of the shoji opening prevention metal fitting 80 in the vertical direction is longer than the length of the aluminum block 74 in the vertical direction.

  Since the drawing piece 72 is a conventional part having a drawing function, it is difficult to increase the length in the vertical direction even though the conventional part can be provided with a shoji opening prevention function. In the present embodiment, in order to compensate for this, the length of the shoji opening prevention metal fitting 80, which is a dedicated member for preventing the shoji opening, is made longer than the length of the drawing piece 72 (aluminum block 74). Therefore, it is possible to give the dedicated member a great function to prevent the opening of the shoji, and it is possible to more appropriately prevent the door toe 56 from opening when a fire occurs and the passage of a flame to occur.

  Further, in the present embodiment, the length in the vertical direction of the shoji opening prevention metal fitting 80 is 8% or more and 12% or less of the length in the vertical direction of the door toe 56.

  If the length in the vertical direction of the shoji opening prevention metal fitting 80 is smaller than 8% of the length in the vertical direction of the door toe 56, the function for preventing the shoji opening does not work sufficiently, while if it is larger than 12%, the length increases. The effect of preventing the opening of shoji is not expected to improve much, and the cost merit is reduced. Therefore, in such a case, it is possible to realize the shoji opening prevention metal fitting 80 that appropriately operates the shoji opening prevention function at low cost.

  Further, in the present embodiment, the flame shielding metal fitting 70 that is continuous in the longitudinal direction of the door end rod 56 is attached to the engagement groove portion 60.

  Therefore, it becomes possible to interrupt a flame appropriately and a fire prevention function improves further.

  In the present embodiment, the thickness of the overlapping portion A of the shoji opening prevention metal fitting 80 is greater than the thickness of the flame shield metal fitting 70.

  Therefore, when the shoji opening prevention metal fitting 80 hits the vertical rail 37, the shoji opening prevention metal fitting 80 is not damaged due to the thick thickness of the shoji opening prevention metal fitting 80, and a reliable block is formed. The Therefore, it is possible to more appropriately prevent the door toe 56 from opening when a fire occurs and causing a flame passage.

  Further, in the present embodiment, a metal reinforcing material (reinforcing material 78) that is continuous in the longitudinal direction of the door end rod 56 is inserted into the engagement groove 60, and the shoji opening prevention metal fitting 80 is reinforced. The material 78 is fixed with screws 90.

  Therefore, even if the door toe 56 is exposed to a flame and melted in the event of a fire, the state in which the shoji opening prevention metal fitting 80 is fixed to the metal reinforcing material (the reinforcing material 78) is maintained. Therefore, it is possible to more appropriately prevent the door toe 56 from opening when a fire occurs and causing a flame passage.

  Further, in the present embodiment, the frame body 20 and the casing 50 (specifically, the upper frame 30, the lower frame 32, the left and right vertical frames 35, the upper casing 52, the lower casing 54, and the left and right casings (doors) While the leading rod 56 and the summoning rod 58)) are made of synthetic resin, the upper frame 30 and the upper rod 52 are provided on the upper frame 30 and the upper rod 52 with the upper frame hanging bracket 31 and the upper rod hanging that overlap each other in the prospective direction when the shoji is closed. A metal fitting 53 is provided. That is, as shown in FIG. 2, the upper frame hanging bracket 31 and the upper rod suspension bracket 53 are fixed to the upper frame 30 and the upper rod 52, respectively, and overlap each other in the prospective direction when the shoji 40 is closed. (Overlapping). In such a state, when a fire occurs, both hanging brackets engage with each other and play a role of hanging the shoji 40. In other words, the upper frame hanging bracket 31 and the upper frame hanging bracket 53 are configured so that the shoji 40 does not fall down (does not collapse) even if the synthetic resin frame 20 and the casing 50 are exposed to a flame and melted in the event of a fire. It is for making.

  In the present embodiment, due to the action of the upper frame hanging bracket 31 and the upper rod hanging bracket 53 described above, the door rod 56 is relatively difficult to open at the upper part of the rod (the door rod 56). The opening prevention metal fitting 80 is provided in the lower part where the door-end fence 56 is easy to open. As described above, in this embodiment, the shoji opening prevention metal fitting 80 is provided at an appropriate position in the door toe 56, so that when the fire occurs, the door toe 56 is opened and a flame passage is formed. This can be prevented more appropriately.

  Further, in the present embodiment, the prevention metal fitting side heating foaming material 85 is attached to the shoji opening prevention metal fitting 80, and the flameproofing metal fitting side heating foaming material 84 is also attached to the flameproofing metal fitting 70. The prevention metal fitting side heating foam material 85 and the flame shield metal fitting heating material 84 are opposed to each other with the vertical rail 37 positioned between the two heating foam materials.

  Therefore, when both of the foamed materials are expanded by being exposed to a flame in the event of a fire, the vertical rail 37 located between the both is sandwiched, and the vertical rail 37 can be prevented from being deformed. It becomes. Therefore, the engagement groove portion 60 formed in the door toe 56 is less likely to be detached from the vertical rail 37, and it is possible to more appropriately prevent the door toe 56 from opening and causing a flame passage when a fire occurs. It becomes possible.

  In the present embodiment, a rail-side heating foam material 86 is attached to the vertical rail 37, and the rail-side heating foam material 86 is composed of a prevention metal fitting-side heating foam material 85 and a flame shield metal fitting-side heating foam material 84. The at least one of the heating foamed materials was opposed to.

  Therefore, since the vertical rail 37 is more reliably sandwiched between the heated foam materials, it is possible to more appropriately suppress the vertical rail 37 from being deformed. Therefore, the engagement groove portion 60 formed in the door toe 56 is more difficult to come off from the vertical rail 37, and it is more appropriately prevented that the door toe 56 is opened and a flame passage is formed when a fire occurs. It becomes possible to do.
