  As shown in FIGS. 5A to 5C and FIG. 7, the metal fitting 40 has a first plate-like portion 40a, a second plate-like portion 40b, and a fixing portion 40c. The first plate-like portion 40a is formed in, for example, a rectangular band shape, and covers the side surface 24g of the resin vertical rod 24b. An adhesive or the like may not be provided between the first plate-like portion 40a and the side surface 24g. The side surface 24g constitutes a part of the outer peripheral surface 25a (see FIG. 1) of the shoji frame 25. For this reason, the 1st plate-shaped part 40a has covered the part along the outer peripheral surface 25a of the shoji frame 25 among the resin vertical rods 24b.

  Similar to the first plate-like portion 40a, the second plate-like portion 40b is formed in, for example, a rectangular belt shape, and covers the bottom surface 24h of the resin vertical rod 24b. The second plate-like portion 40b is bent at an angle of 90 ° with respect to the first plate-like portion 40a. An adhesive or the like may not be provided between the second plate-like portion 40b and the bottom surface 24h. The bottom surface 24h constitutes a part of the outer peripheral surface 25a (see FIG. 1) of the shoji frame 25, similarly to the side surface 24g. For this reason, the 2nd plate-shaped part 40b has covered the part along the outer peripheral surface 25a of the shoji frame 25 among the resin vertical rods 24b. The second plate portion 40b is formed integrally with the first plate portion 40a. For this reason, it is in the state where the corner part of the lower side of the door end of resin vertical gutter 24b was covered.

  The fixed part 40c is connected to the first plate-like part 40a via the connecting part 40f. In the present embodiment, the side surface 24g of the resin vertical rod 24b is disposed on the right vertical frame 14 side with respect to the side surface 24f of the metal vertical rod 24a. For this reason, the connecting portion 40f is formed so that the fixed portion 40c and the first plate-like portion 40a both come into contact with the target surface (the side surface 24f of the metal vertical rod 24a and the side surface 24g of the resin vertical rod 24b). The fixing portion 40c is formed in a rectangular plate shape, and is in contact with the side surface 24f of the metal vertical rod 24a. The fixing part 40c has openings 40e at two places, for example. A fixing member 42 such as a screw is inserted into the opening 40e. A heating foam material 40d is attached to the surface of the fixed portion 40c (the surface facing the right vertical frame 14). A through hole for inserting the fixing member 42 is provided at a position overlapping the opening 40e in the heating foam material 40d.

  In the present embodiment, the first plate-like portion 40a and the second plate-like portion 40b cover the side surface 24g and the bottom surface 24h of the resin vertical rod 24b by fixing the metal fitting 40 to the metal vertical rod 24a by the fixing member 42. The shoji 20 can be easily manufactured.

  As shown in FIGS. 6A, 6B, and 7, the metal fitting 41 has a cover portion 41a and a fixing portion 41b. The cover part 41a is formed in, for example, a rectangular band shape, and is in a state in which corners are notched. The cover portion 41a covers the bottom surface 22g of the resin lower bar 22b. An adhesive or the like may not be provided between the cover portion 41a and the bottom surface 22g. The bottom surface 22g constitutes a part of the outer peripheral surface 25a (see FIG. 1) of the shoji frame 25. For this reason, the cover part 41a has covered the part along the outer peripheral surface 25a of the shoji frame 25 among the resin lower crosspieces 22b.

  The fixing part 41b is formed integrally with the cover part 41a. The fixing portion 41b is formed in a rectangular plate shape, and is in contact with the bottom surface 22f of the metal lower bar 22a. The fixed part 41b has openings 41c at two places, for example. A fixing member 43 such as a screw is inserted into the opening 41c. A heating foam material 41d is affixed to the surface of the fixing portion 41b (the surface facing the lower frame 12). A through hole for inserting the fixing member 43 is provided at a position overlapping the opening 41c in the heating foam material 41d.

  In this embodiment, by fixing the metal fitting 41 to the metal lower rail 22a by the fixing member 43, the shoji 20 having a configuration in which the cover portion 41a covers the bottom surface 22g of the resin lower rail 22b can be easily manufactured.

  In the conventional opening device 200 having the configuration in which the metal fittings 40 and 41 are not provided in the above configuration, when a fire occurs indoors, as shown in FIG. 9, as shown in FIG. And so on). In this case, the shoji 120 is warped at the dropping portion of the resin vertical rod 124b, and a gap formed between the shoji 120 and the frame 110 is increased. For this reason, the space inside and outside the opening device 200 may penetrate.

  Further, as shown in FIG. 9, in addition to the resin vertical rod 124b, the resin vertical frame 114b, the door-to-door packing 118, and other portions formed of the resin material fall off. For this reason, even when the warp of the shoji 120 is not formed, a linear gap (indicated by an arrow in the figure) may be formed between the shoji 120 and the frame 110.

  On the other hand, in the building provided with the opening device 100 according to the present embodiment, when a fire occurs indoors, resin materials (resin upper rail 21b, resin lower rail 22b, resin vertical gutters) arranged on the indoor side are similarly used. 23b and 24b) melt at high temperatures and fall off. At this time, in this embodiment, the metal fittings 40 and 41 remain even when the resin material (21b to 24b) is dropped. That is, as shown in FIG. 8, the first plate-like portion 40a and the second plate-like portion 40b of the metal fitting 40 are arranged on the side surface 24g and the bottom surface 24h of the resin vertical rod 24b, and on the bottom surface 22g of the resin lower rail 22b. Will be in the state where the cover part 41a of the metal fitting 41 is arranged. Thereby, since the expansion of the clearance gap between the shoji 20 and the frame 10 is suppressed, the space inside and outside the opening part apparatus 100 becomes difficult to penetrate.

  In addition, the heating foam 40d provided on the metal fitting 40 and the heating foam 41d provided on the metal fitting 41 are foamed by heat and enter between the metal fittings 40, 41 and the right vertical frame 14 and the lower frame 12. Therefore, the space between the shoji 20 and the frame 10 can be closed. Thereby, it can prevent that the space of the room | chamber interior and the outdoor penetrates.

  Moreover, the warp of the shoji 20 occurs more greatly on the upper side than the lower side of the shoji 20. On the other hand, since the temperature of the upper side of the shoji 20 is higher than that of the lower side, the heating foam material disposed on the upper side of the frame body 10 among the heating foam materials 51 to 66 is disposed on the lower side of the frame body 10. Swells faster than heated foam. Thus, since the space between the shoji 20 and the frame 10 is closed earlier than the lower side, the space between the room and the outside is difficult to penetrate on the upper side of the shoji 20. On the other hand, since heat is not easily transmitted to the lower side of the frame body 10, the foaming timing may be delayed for the heated foam material disposed below the frame body 10 among the heated foam materials 51 to 66. is there. In this case, since the metal fittings 40 and 41 are not provided in the conventional configuration, the space between the room and the outside penetrates from when the lower side of the shoji is warped until the gap is closed by the heating foam material. There was a case. On the other hand, in this embodiment, since the metal fittings 40 and 41 are provided in the lower corner part of the shoji 20, the spread of the clearance gap between the shoji 20 and the frame 10 will be suppressed. Thereby, it becomes possible to prevent the space between the room and the outdoor from penetrating more reliably.

  Moreover, in this embodiment, as shown in FIG. 10, since the metal fittings 40 and 41 remain even if the resin material (21b to 24b) falls off, a linear shape is formed between the shoji 20 and the frame body 10. Formation of a gap can be avoided. Thereby, it becomes possible to prevent the space between the room and the outdoor from penetrating more reliably.

  As mentioned above, according to this embodiment, the metal fittings 40 and 41 which cover the part along the outer peripheral surface 25a of the shoji frame 25 among resin materials (21b-24b) are being fixed to the metal material (21a-24a). Therefore, even when a fire occurs in the room and the resin material (21b to 24b) falls off, the state where the outer peripheral surface 25a of the shoji frame 25 is covered with the metal fittings 40 and 41 is maintained. In this case, since the spread of the gap between the shoji 20 and the frame 10 is suppressed, the space inside and outside the opening device 100 is difficult to penetrate. Thereby, it becomes possible to improve a flame-shielding property.

The technical scope of the present invention is not limited to the above-described embodiment, and appropriate modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the opening device 100 using the composite material of metal and resin has been described. However, the present invention is not limited to the composite sash, and can be applied to a metal sash. Nor.

  In the above embodiment, an opening device having a so-called swing-type shoji has been described as an example. However, the present invention is not limited to this, and the opening device having a sliding-type shoji, The present invention can also be applied to an opening device having a sliding type shoji.

  In addition, with respect to the configuration of the above embodiment, for example, a heating foam material (heating foam material 63 and the like) provided in the right vertical frame 14 is disposed at a position facing the first plate-like portion 40a and the fixing portion 40c of the metal fitting 40. It may be a configured. Similarly, the heating foam material (heating foam material 54 etc.) provided in the lower frame 12 is arranged at a position facing the second plate-like portion 40b of the metal fitting 40 and the cover portion 41a of the metal fitting 41. Also good.

  Moreover, although the said embodiment gave and demonstrated the structure by which the metal fittings 40 and 41 were attached to the lower side of the door end of the shoji 20, it is not restricted to this. For example, even if the metal fittings 40 and 41 are disposed at any position on the outer peripheral surface 25a of the shoji 20, it is possible to obtain the same effect as in the above embodiment.
