The straight portion 163b is located on the outdoor side (the side where the shoji 20 opens) of the arc portion 163c, and restricts the movement of the shaft portion 521 of the lock pin 52 in the expected direction. The inclined portion 163a is located on the outdoor side of the entrance of the notch portion 163, and is inclined toward the outdoor side as it descends from the lower end portion of the straight portion 163b.

In the notch 163, when the shaft portion 521 of the lock pin 52 is located in the range of the length L1 excluding the inclined portion 163a, the shaft portion is formed by the straight portion 163b extending in the direction orthogonal to the moving direction even if the shoji 20 tries to open. The movement of 521 is surely blocked. In the above-mentioned engaging position, the center of the shaft portion 521 of the lock pin 52 is within the range of the length L2 of the straight portion 163b. When the shaft portion 521 of the lock pin 52 moves by a length L3 from the engaging position, it reaches the inclined portion 163a. As long as it is located within the range of the length L2 of the notch 163, the linear portion 163b extending in the orthogonal direction prevents the shaft portion 521 from moving.

On the other hand, the length (hanging allowance) in the vertical direction in the range where the warp prevention metal fitting 95 and the warp prevention receiving metal fitting 96 overlap in the expected direction is defined as the length d2 (see FIG. 17). In the present embodiment, the length d2 of the hooking allowance of the warp prevention metal fitting 95 and the warp prevention receiving metal fitting 96 is configured to be longer than the length L2 of the straight line portion 163b described above. When the relationship of length d2> length L2 is established, the door end side of the shoji 20 is lowered due to melting or the like at the time of a fire, the center of the shaft portion 521 is lowered to the position of the inclined portion 163a, and the length of the straight portion 163b. Even if it deviates from the range of L2, the opening of the shoji 20 can be reliably prevented by the warp prevention metal fitting 95 and the warp prevention receiving metal fitting 96 within the range of the length d2 of the hooking allowance.

Further, as shown in FIG. 17, the shaft portion 521 disengages from the notch portion 163 from the engaging position that has entered the inside of the notch portion 163, and does not interfere with the notch portion 163 including the inclined portion 163a when the shoji 20 opens. Let the distance to the position be the length d1. In the present embodiment, the shape and mounting position of the warp prevention metal fitting 95 and the warp prevention receiving metal fitting 96 are set so that the length d2 is longer than the length d1. That is, the relationship of length d2> length d1 is also established. As a result, even when the door end side of the shoji 20 is lower than the length L2 and the lock pin 52 is about to be disengaged from the lock pin receiving metal fitting 16, the warp prevention metal fitting 95 and the warp prevention receiving metal fitting 96 are engaged with each other. The opening of the shoji 20 can be prevented. In the normal opening operation of the shoji 20, the slide plate 51 is moved downward by the handle mechanism 57 so as to exceed the range of the length d2. Therefore, when the shoji 20 is opened, the warp prevention metal fitting 95 and the warp prevention receiving metal fitting 96 are used. Does not interfere.

A pedestal portion 315 having a length may be arranged to arrange the core material connecting metal fitting 70.

In the above embodiment, the thickness of the door end side vertical stile 34 is secured by each of the outdoor side hollow portion 34a and the indoor side hollow portion 34b, and the slide plate 51 is the door end surface of the door end side vertical stile 34. It is configured to be located approximately in the center of the expected direction. As a result, the slide plate 51 is difficult to separate from the door end side vertical frame 34 regardless of whether the flame source is on the outdoor side or the indoor side. In addition, the core material connecting metal fittings 70 and 71 prevent the frame 30 from being separated indoors. As described above, since the warp prevention metal fitting 95 is fixed to the slide plate 51 that is firmly held even in the event of a fire, a configuration that can more reliably prevent the warp of the door end side vertical frame 34 is realized.

A modified example of the above embodiment will be described. In the following description, the same reference numerals may be given to the configurations common to or similar to those of the above embodiment, and the description thereof may be omitted.

FIG. 19 is a perspective view showing the warp prevention metal fitting 97 fixed to the slide plate 51a of the modified example and its surroundings. In this modification, the method of fixing the warp prevention metal fitting 97 to the slide plate 51a is different from that of the above embodiment. The structure of the warp prevention metal fitting 97 is the same as that of the warp prevention metal fitting 95 of the above embodiment, and is composed of a fixing portion 951, an inclined portion 952, an engaging portion 953, and a bending portion 954.

As shown in FIG. 19, a through hole 98 for attaching the warp prevention metal fitting 97 is separately formed in the slide plate 51a of the modified example. The warp prevention metal fitting 97 is set on the back side of the slide plate 51a so that the engaging portion 953 protrudes from the through hole 98. In the warp prevention metal fitting 97, a fixing portion 951 located on the back side of the slide plate 51a is fastened and fixed from the surface of the slide plate 51a by screws 956.

That is, a through hole 98 for attaching the warp prevention metal fitting 97 is formed in the slide plate 51a of the fitting 1 of the modified example, and the warp prevention metal fitting 97 is provided from the fixing portion 951 and the fixing portion 951 located on the back side of the slide plate 51a. It has an engaging portion 953 that projects toward the door end side through the through hole 98.

The warp prevention metal fitting 97 of this modification also has the same effect as the warp prevention metal fitting 95 of the above embodiment. Further, since it is not necessary to prepare the back plate 955 for fixing the warp prevention metal fitting 97 to the slide plate 51a, it is possible to prevent the warp prevention of the door end side vertical frame 34 with a simple configuration. Further, in the work of fixing the warp prevention metal fitting 97 to the slide plate 51a, it is not necessary to perform the fastening work while pressing the back plate, so that the work process can be facilitated.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiments and modifications, and can be appropriately modified. For example, the frame body 10 and the frame body 30 of the above embodiment are both made of resin, but at least one of the frame body 10 and the frame body 30 in the prospective direction outdoor side and the indoor side is made of metal such as aluminum. The cover member may be additionally arranged. That is, the resin frame and the resin frame may have a metal member attached to the inside, the indoor side, or the outdoor side thereof. Further, the present invention is not limited to a resin frame or stile, but can be applied to a metal frame or stile such as aluminum, an aluminum resin composite sash, or the like. Further, in the above embodiment, the lock pin and the lock pin receiving metal fitting are arranged at two upper and lower positions, but the configuration is not limited to this. For example, a configuration in which three or more lock pins and lock pin receiving metal fittings are arranged may be used.

Further, in the above embodiment, the self-propelled door is described as an example of the fitting of the present invention, but the present invention is not limited to this configuration, and various configurations including a swing-type opening / closing door, an opening / closing window, and the like for opening and closing the shoji screen are provided. The present invention can be applied to fittings.
