  Here, in the above conventional door, as described above, since the rigidity of the thermal expansion refractory member is relatively low, the thermal expansion refractory member is crushed when the surface material and each force bone are joined by rivets. Therefore, deformation (specifically, dent deformation) is likely to occur in the vicinity of the joint portion of the rivet in the surface material. For example, if the deformation amount of the surface material becomes excessive, (Near the joint portion of the rivet) is noticeable, there is a possibility that the design of the door is reduced. Therefore, there is room for improvement from the viewpoint of design.

The outdoor-side deformation suppressing unit 71 is a deformation suppressing unit for suppressing the deformation of the outdoor-side surface member 40a, and the indoor-side deformation suppressing unit 72 is a deformation suppressing unit for suppressing the deformation of the indoor-side surface member 40b. is there. The outdoor-side deformation suppressing portion 71 and the indoor-side deformation suppressing portion 72 are flat substantially plate-like members, and are provided between the outdoor-side surface material 40a or the indoor-side surface material 40b and the first heat shield 61, respectively. Have been. More specifically, as shown in FIG. 6B, the outdoor-side deformation suppressing portion 71 is configured such that the outdoor-side surface material 40 a has a space 41 between the outdoor-side surface material 40 a and the first heat-shielding portion 61.

In addition, the indoor-side deformation suppressing unit 72 is configured to contact the prospect-side part 41 and the first heat-shielding part 61 between the prospect-side part 41 and the first heat-shielding part 61 of the indoor-side surface material 40b. It is arranged and spaced apart from the outdoor-side deformation suppressing portion 71.

  Further, the specific shape and size of the outdoor-side deformation suppressing unit 71 and the indoor-side deformation suppressing unit 72 can be arbitrarily set as long as the deformation of the outdoor-side surface material 40a or the indoor-side surface material 40b can be suppressed. However, in the embodiment, the settings are as follows. That is, the planar shapes of the outdoor-side deformation suppressing unit 71 and the indoor-side deformation suppressing unit 72 are set to be substantially rectangular. The length in the left-right direction of the outdoor-side deformation suppressing portion 71 and the indoor-side deformation suppressing portion 72 is set to be substantially the same as the length in the left-right direction of the central piece 36a of the upper lateral force bone 33.

It can be fixed to any part of 41, and it becomes easy to fix the outdoor-side fixture 81 and the indoor-side fixture 82 described later.

  Further, the method of forming the outdoor-side deformation suppressing portion 71 and the indoor-side deformation suppressing portion 72 is arbitrary, but in the embodiment, the outdoor-side deformation suppressing portion 71 has the expected side portion 41 of the outdoor-side surface material 40a. It is formed by folding at least once, and more specifically, as shown in FIG. 6 (b), it is formed by folding the prospective side portion 41 of the outdoor surface material 40a only once. In addition, the indoor-side deformation suppressing portion 72 is formed by folding the prospective side portion 41 of the indoor-side surface material 40b one or more times. Specifically, as shown in FIG. It is formed by folding the prospective side portion 41 of the surface material 40b only once. Thereby, the fold portion of the outdoor-side deformation suppressing portion 71 and the indoor-side deformation suppressing portion 72 can be formed in a curved shape, and the outdoor-side surface material 40a and the outdoor-side deformation suppressing portion 71 are formed separately (or indoor side). (In the case where the surface material 40b and the indoor-side deformation suppressing portion 72 are formed separately), it is easier to ensure the safety in use of the opening / closing body 20, and the first heat shield 61 is made of a thermal expansion refractory member. In this case, the first heat shield 61 is easily expanded so as to expand toward the outside of the opening / closing body 20. Further, the number of parts of the opening / closing body 20 can be reduced, and the manufacturing cost of the opening / closing body 20 can be reduced.

  Here, the method of fixing the outdoor surface material 40a and the indoor surface material 40b is arbitrary, but in the embodiment, the outdoor surface material 40a is, as shown in FIG. The prospective side portion 41 is fixed to the central piece 36a of the upper lateral force bone 33 by the outdoor fixing tool 81 via the outdoor deformation suppressing portion 71 and the first heat shielding portion 61.

It is fixed by being attached to the central piece 36a of the upper lateral force bone 33 through the intermediary. Further, as shown in FIG. 6, with respect to the indoor side surface member 40 b, the prospective side portion 41 of the indoor side surface member 40 b is connected to the upper lateral force bone 33 via the indoor side deformation suppressing portion 72 and the first heat shielding portion 61.

It is fixed by being attached to the central piece 36a of the upper lateral force bone 33 through the intermediary. In addition, the above-mentioned "outdoor-side fixing tool 81" and "indoor-side fixing tool 82" correspond to the "fixing tool" in the claims.

  In this case, the specific configuration of the outdoor-side fixing device 81 and the indoor-side fixing device 82 is arbitrary, but in the embodiment, the outdoor-side surface material 40a and the indoor-side surface material 40b are connected to the upper lateral force bone 33. In order to firmly fix it, it is configured using screws. The specific configuration of the outdoor-side surface material 40a, the indoor-side surface material 40b, the outdoor-side deformation suppressing unit 71, and the indoor-side deformation suppressing unit 72 is arbitrary. For example, the outdoor-side fixing member 81 or the indoor side In order to enhance the attachment of the fixing device 82, the fixing device 82 may be configured as follows. That is, an insertion hole for inserting the outdoor-side fixing tool 81 or the indoor-side fixing tool 82 into each of the outdoor-side surface material 40a, the indoor-side surface material 40b, the outdoor-side deformation suppressing unit 71, and the indoor-side deformation suppressing unit 72.

The length of the side portion 41 and the outdoor-side deformation suppressing portion 71 may be set to such an extent that the side portion 41 and the outdoor-side deformation suppressing portion 71 overlap. Substantially the same). By attaching the outdoor fixing member 81 to the vicinity of the fold of the outdoor deformation suppressing portion 71, the length of the outdoor deformation suppressing portion 71 in the front-rear direction can be shortened. (Note that the same applies to the indoor fixture 82).

  According to the second feature, the deformation (specifically, the dent deformation) of the outdoor surface material 40a due to the fixing of the outdoor surface material 40a by the outdoor fixing device 81 can be suppressed, and the indoor fixing device 82 can be suppressed. The deformation of the indoor side surface material 40b due to the fixing of the indoor side surface material 40b due to the above can be suppressed. In particular, even if the outdoor fixture 81 and the indoor fixture 82 are screws, the deformation of the outdoor surface material 40a and the deformation of the indoor surface material 40b can be suppressed. Therefore, compared with the prior art (the technique of fixing the portion on the side of the expected surface of the surface material to each force bone via the thermal expansion refractory member) with the rivet, the outdoor surface material 40a or the indoor surface material 40b is not used. Since the deformation can be prevented from becoming excessive, the design of the opening / closing body 20 can be maintained.

The prospective side portion 41 of the indoor-side surface material 40b is arranged so as to abut on each other at an interval.

  Specifically, the indoor end of the room at the prospective portion 41 of the outdoor surface material 40a and the outdoor end of the room at the prospective portion 41 of the indoor surface material 40b do not abut. They are arranged facing each other. In this case, the length of the interval is arbitrary, but from the viewpoint of maintaining the design of the opening / closing body 20, the outdoor fixture 81 can be fixed to the outdoor surface material 40a, and the indoor surface material 40b It is desirable to set as short as possible as long as the indoor fixture 82 can be fixed to the inside.

  Due to such a third feature, the outdoor side surface material is compared with a case where the prospect side portion 41 of the outdoor side surface material 40a and the prospect side portion 41 of the indoor side surface material 40b are arranged without a space therebetween. Heat conduction between the interior surface member 40b and the interior surface member 40b can be avoided, and the heat shielding performance of the opening / closing body 20 can be easily enhanced.

Since heat conduction between the power bones 33 and the power bones 33 can be easily avoided, the heat shielding performance of the opening / closing body 20 can be further enhanced. In addition, since the first heat shield 61 is disposed so as to contact each of the second indoor heat shield 62 and the second indoor heat shield 63, the first heat shield 61 is located outside the second indoor heat shield 63. The central piece 36a of the upper lateral force bone 33 and the outdoor-side surface material 40a (or the indoor-side surface material) are different from the case where the heat-shielding portion 62 and the second indoor-side heat-shielding portion 63 are arranged with a gap therebetween. 40b) to suppress heat conduction between the prospective side portion 41 or between the central piece 36a of the upper lateral force bone 33 and the outdoor deformation suppressing portion 71 (or the indoor deformation suppressing portion 72).

Further, the number of parts of the opening / closing body 20 can be reduced, and the manufacturing cost of the opening / closing body 20 can be reduced.

  In addition, since the first heat shield 61 is a thermal expansion refractory member, the first heat shield 61 expands due to the heat of the fire, so that the outdoor member 40a or the indoor member 40b and the support member are mutually reciprocated. The gap between them can be closed, and the heat shielding performance of the opening / closing body 20 can be further enhanced. In addition, even if the first heat shield 61 is a thermal expansion refractory member, the outdoor-side fixing member 81 or the outdoor-side surface material 40a by the indoor-side fixing member 82 by the outdoor-side deformation suppressing portion 71 and the indoor-side deformation suppressing portion 72. Since the deformation of the outdoor-side surface material 40a or the indoor-side surface material 40b due to the fixing of the indoor-side surface material 40b can be suppressed, the design of the opening / closing body 20 can be easily maintained.

  Further, since the outdoor fixing member 81 and the indoor fixing member 82 are screws, the outdoor surface member 40a or the indoor surface member 40b can be firmly fixed to the support member. Further, even if the outdoor-side fixing tool 81 and the indoor-side fixing tool 82 are screws, the outdoor-side fixing tool 81 or the outdoor-side surface material by the indoor-side fixing tool 82 by the outdoor-side deformation suppressing unit 71 and the indoor-side fixing unit 72.

Although the outdoor deformation suppressing portion 71 and the first heat shielding portion 61 are described as being mounted on the upper surface of the upper lateral force bone 33, the present invention is not limited to this. For example, as shown in FIG. 8, the front end of the first heat shield 61 is located outside (in front of) the front end of the outdoor deformation suppressing portion 71 and the front end of the central piece 36 a of the upper lateral force bone 33. ), The outdoor deformation suppressing portion 71 and the first heat shield 61 may be mounted on the upper surface of the upper lateral force bone 33 (the rear end of the first heat shield 61 and the chamber). The arrangement relationship between the rear end of the inner deformation suppressing portion 72 and the rear end of the central piece 36a of the upper lateral force bone 33 is substantially the same. In this case, for example, the outdoor deformation suppressing portion 71 may be formed such that the front end of the outdoor deformation suppressing portion 71 is substantially flush with the front end of the central piece 36a of the upper lateral force bone 33. . Alternatively, as shown in FIG. 8, in order to reduce the material cost of the outdoor-side deformation suppressing unit 71, the front end of the outdoor-side deformation suppressing unit 71 is positioned in a more probable direction than the front end of the central piece 36 a of the upper lateral force bone 33.

Although it is caused by the omission of the inner deformation suppressing portion 72, the dent deformation in the outdoor surface material 40a or the indoor surface material 40b is hardly noticeable from the outside, so that the design of the opening / closing body 20 can be prevented from deteriorating. On the other hand, when the outdoor-side deformation suppressing portion 71 and the indoor-side deformation suppressing portion 72 are omitted in the heat shielding structure on the door end side of the opening / closing body 20 or the heat shielding structure on the door end side of the opening / closing body 20, When at least a part of the opening 3 is opened, the door-side side surface and the door-side side surface of the opening / closing body 20 are easily visible from the front direction or the rear direction. The dent deformation is more conspicuous in the outdoor-side surface material 40a or the indoor-side surface material 40b caused by the omission of the suppressing portion 72.
