  More specifically, between the frame 2 and the frame 5, more specifically, between the left frame member 20 of the frame 2 and the left frame member 50 of the frame 5 and the right frame member 20 of the frame 2. A link mechanism 8 as a part for moving the shoji 3 to open and close is provided between the right frame 50 of the frame 5 and the frame 20 on the lower side of the frame 2 and the frame 5. Latch mechanisms 9 are provided between the lower saddle member 50 as components for maintaining the shoji 3 closed.

  Since the structure in which the link mechanism 8 or the latch mechanism 9 is attached between the frame member 20 and the frame member 50 on the left and right and the lower side of the joinery 1 is the same, here, the left frame member 20 of the frame 2 is used. An example of the attachment structure of the link mechanism 8 that is attached between the housing 5 and the left brace 50 of the housing 5 will be described.

  As shown in FIG. 3, the link mechanism 8 includes a frame fixing portion 8 a and a hook fixing portion 8 b that are fixed to the left frame member 20 and the left hook member 50. The saddle fixing portion 8b forms a saddle chamber exterior 512 included in the left saddle member 50, and is in contact with the saddle outer peripheral wall portion 512b that forms the outer peripheral surface 5a facing the inner peripheral surface 2a of the left frame member 20, A screw (not shown) penetrating with the outer peripheral wall portion 512b is screwed and fixed to the reinforcing member 11 provided in the hollow portion 512a provided in the outer portion 512 of the outer chamber.

  The coffin reinforcing member 11 provided in the hollow portion 512a of the coffin chamber exterior 512 has a U-shaped cross section so that the two U-shaped opposing wall portions 11a face each other in the inner and outer peripheral directions. The two walls 11a are connected to each other at the outer edges by connecting portions 11b. The two wall portions 11a are disposed in the vicinity of the heel outer peripheral wall portion 512b and the heel inner peripheral wall portion 512c facing the heel outer peripheral wall portion 512b in the tub outer portion 512, respectively. A thermally expandable graphite 15 as a heating foam material is provided on the facing surface.

  The frame fixing portion 8a forms a frame body main body portion 21 provided in the left frame member 20, and abuts against a frame inner peripheral wall portion 21c that forms an inner peripheral surface 2a that faces the outer peripheral surface 5a of the left brim member 50. The screws 16 penetrating together with the frame inner peripheral wall portion 21c are screwed and fixed to the fixing member 12 provided in the hollow portion 21a included in the frame material main body portion 21.

  As shown in FIGS. 3 and 4, the fixing member 12 is formed by bending a steel plate, and includes two plate portions 121 and 122 that face each other at an interval in the left-right direction, and two plate portions 121 and 122. It has the connection board part 123 which connects the indoor edges, and is provided over substantially the full length of the frame material 20 on the left side. The two plate portions 121 and 122 have a prospective direction in which the outer plate portion 121 as the fixed opposing wall portion located on the left side, that is, the outer peripheral side is more likely than the inner plate portion 122 as the contact fixed wall portion located on the right side, that is, the inner peripheral side. The outer plate part 121 protrudes from the inner plate part 122 to the outdoor side.

  The fixing member 12 provided in the hollow portion 21a of the left frame member 20 is fixed by a screw 16 that fixes the link mechanism 8 with the inner plate portion 122 abutting against a portion of the inner surface of the frame inner peripheral wall portion 21c on the indoor side. Is done. For this reason, the outer plate portion 121 of the fixing member 12 has the resin facing portion 121a opposed to the frame inner peripheral wall portion 21c in the state where the link mechanism 8 is attached, and the indoor portion is the inner plate. A metal facing portion 121b facing the portion 122 is formed. Further, the heat-expandable graphite 15 is provided on the resin facing portion 121a of the outer plate portion 121 over the almost entire length of the fixing member 12 at a position facing the surface on the inner plate portion 122 side, that is, the frame inner peripheral wall portion 21c. ing.

  The fixing members 12 provided on the left and right frame members 20 and the lower frame member 20 in the frame 2 are connected to each other by the connecting members (not shown) at the corners of the frame 2. Yes.

  According to the fitting 1 of this embodiment, in order to fix the link mechanism 8 or the latch mechanism 9 attached to the frame member 20 of the synthetic resin frame member 20 and the saddle member 50 that face each other when the shoji 3 is closed. The metal fixing member 12 has a frame inner peripheral wall portion 21c as the other facing wall portion facing the brazing member 50 as the other hollow member in the hollow portion 21a of the frame member 20 as one hollow member. Since the link mechanism 8 or the latch mechanism 9 is fixed in contact with the frame mechanism 20, even if the frame member 20 is melted, the link mechanism 8 or the latch mechanism 9 can be held.

  The fixing member 12 is spaced apart from the frame inner peripheral wall portion 21c, which is provided separately from the inner plate portion 122 that is in contact with the frame inner peripheral wall portion 21c and to which the link mechanism 8 or the latch mechanism 9 is fixed. Since the thermally expandable graphite 15 is provided on the surface of the opposed outer plate portion 121 on the inner plate portion 122 side, the thermally expandable graphite 15 foams toward the inner plate portion 122 side when heated. When the frame inner peripheral wall portion 21c of the frame member 20 is melted, the expanded thermally expandable graphite 15 can enter between the frame body 2 and the casing 5 to be filled. For this reason, even if the frame member 20 is melted, it is possible to prevent the penetration of the flame.

  In addition, since the fixing member 12 provided with the thermally expandable graphite 15 is provided in the hollow portion 21a of the frame member 20, even if the shoji 3 is opened, the thermally expandable graphite 15 is exposed to the outside. The design of the joinery 1 is not impaired. For this reason, even if it is the joinery 1 provided with the frame 2 and the frame 5 made of synthetic resin, it is possible to provide the joinery 1 that is difficult to penetrate the flame and that has excellent design.

  Moreover, since the outer plate part 121 provided with the thermally expandable graphite 15 has the metal facing part 121b and the resin facing part 121a facing the frame inner peripheral wall part 21c, the frame inner peripheral wall part 21c is melted. When the thermally expandable graphite 15 is foamed while penetrating, it passes between the frame inner peripheral wall portion 21c in which the thermally expandable graphite 15 provided in the resin facing portion 121a is melted and between the frame body 2 and the casing 5. enter in. That is, when the joinery 1 is heated, the heat-expandable graphite 15 provided in the resin facing portion 121a foams without being blocked by the inner plate portion 122 and enters between the frame body 2 and the casing 5. It is possible. For this reason, it is possible to make the thermally expandable graphite 15 enter between the frame body 2 and the housing 5 more reliably.

  Further, since the thermally expandable graphite 15 is provided at a portion where the outer plate 121 protrudes from the inner plate 122 contacting the frame inner peripheral wall 21c, the thermally expandable graphite 15 is opposed to the inner plate 122. It opposes the frame inner peripheral wall 21c without doing. For this reason, when the frame inner peripheral wall portion 21c is melted and penetrated, the thermally expandable graphite 15 provided at a position facing the frame inner peripheral wall portion 21c is foamed, and the space between the frame body 2 and the casing 5 is increased. It is possible to enter without trouble.

  In the said embodiment, although the example which provided the thermally expansible graphite 15 in the resin opposing part 121a of the outer-plate part 121 of the fixing member 12 was demonstrated, it does not restrict to this. For example, as the second embodiment, as shown in FIGS. 5 and 6, the thermally expandable graphite 15 is attached to almost the entire surface of the outer plate portion 171 of the fixing member 17 on the inner plate portion 172 side. The portion 172 may be provided at a plurality of positions with appropriate widths in the longitudinal direction only at a portion where a screw for fixing the link mechanism 8 or the latch mechanism 9 is screwed. In the case of the second embodiment, since the thermally expandable graphite 15 provided on the outer plate portion 171 and the frame inner peripheral wall portion 21c face each other between the inner plate portions 172 provided at a plurality of locations, the thermally expandable graphite. When 15 is heated and the inner peripheral wall portion 21c melts and penetrates, the thermally expansible graphite 15 foamed from between the inner plate portions 172 is caused to enter between the frame body 2 and the casing 5 It is possible to charge.

  Moreover, in the said embodiment, although the fixing member 12 was comprised by one member, the fixing member 12 may be comprised by the some member. For example, as shown in FIGS. 7 and 8, as the third embodiment, the fixing member 17 of the second embodiment is an outer member, and the cross-sectional shape is inside the outer member 17 from the fixing member 17 of the second embodiment. It may be a fixing member 19 in which a small U-shaped metal inner member 18 is arranged and fixed with screws. In this case, the inner plate portion of the plate portion 181 on the side adjacent to the inner plate portion 172 to which the link mechanism 8 or the latch mechanism 9 of the outer member 17 among the plate portions 181 of the inner member 18 facing each other is fixed. Thermally expandable graphite 15 is affixed to the surface on the 172 side. Here, the inner member 18 corresponds to a heating foam mounting member.

  In the case of the third embodiment, the outer member 17 to which the link mechanism 8 or the latch mechanism 9 is fixed and the inner member 18 to which the thermally expandable graphite 15 is attached are separate members. Can be brought closer to the frame inner peripheral wall portion 21c. For this reason, it is possible to more reliably fill the heat-expandable graphite 15 that has been heated and expanded by entering between the frame body 2 and the housing 5. Moreover, since the shape of the outer member 17 is not restrained by the arrangement of the thermally expandable graphite 15, it can be made to function as a reinforcing member by enlarging the outer member 17, for example. That is, the fixing member 19 composed of a plurality of members reinforces the frame material 20 and allows the thermally expandable graphite 15 to enter between the frame body 2 and the casing 5 to be filled, so that fire resistance is excellent. The joinery 1 can be provided. At this time, the outer member 17 constituting the fixing member 19 corresponds to a reinforcing member.

Further, the shape of the outer member 17 and the inner member 18 is not limited to a U-shaped cross section, and the outer member 17 and the inner member 18 are joined to each other, and the portion fixed to the frame inner peripheral wall portion 21c is fixed. It may have any shape as long as the thermally expandable graphite 15 is attached to face the inner circumferential wall portion 21c.
In the above embodiment, the parts attached between the two hollow members are the link mechanism 8 and the latch mechanism 9, but the present invention is not limited thereto, and may be a crescent lock, for example.

  In the above-described embodiment, the fixing members 12 and 19 in which the thermally expandable graphite 15 is attached to the surface of the fixed opposing wall 121 on the side of the contact fixing wall 122 are the frame member 20 and the saddle member 50. Although the example provided only in the frame material 20 was demonstrated, the fixing members 12 and 19 may be provided only in the frame material 50 or the frame material 20 and the frame material 50, respectively.

  Moreover, in the said embodiment, although the example which affixed the thermally expansible graphite 15 to the fixing member 12 in the hollow part 21a of the frame material 20 was demonstrated, you may provide in the hollow part 511a of the brazing material 50. FIG. . Moreover, although the example which made the two hollow members the frame material 20 and the eaves material 50 was given and demonstrated, it is not restricted to this, For example, eaves materials used as the summon part of a sliding shoji, or as shown in FIG. It is also possible to adopt a configuration in which the thermally expandable graphite 15 is expanded between the brazing material 50 and the vertical bone 30.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
