The following describes an embodiment of the present invention with reference to the drawings. Figures 1 to 3 show a first embodiment of the fitting of the present invention (an embodiment of the invention according to claims 1 and 2). This fitting is applied to an entrance door of a house, and comprises a frame 1 that is attached to an opening in the building frame, and a door 2 that is attached to the frame 1 by means of hinges 10 so that it can be opened by pivoting to the outside.

The frame 1 is formed by arranging an upper frame 11, a lower frame 12, a door end side vertical frame 13, and a hanging side vertical frame 14, which are all made of extruded aluminum alloy profiles.
As shown in Figure 1, the door-end side vertical frame 13 and the hanging side vertical frame 14 have a hollow section 15 with a roughly rectangular cross section on the outside of the room, with an inner peripheral projection surface 16 extending from the hollow section 15 to the inside of the room, and a door stopper section 17 protruding to the inner peripheral side is formed at the indoor end of the projection surface 16. A resin cover material 18 is attached to the indoor side of the door stopper section 17.
A first waterproofing material 3 is attached to the inner peripheral projecting surface 16 of the door end vertical frame 13 and the hanging end vertical frame 14, and the first waterproofing material 3 is curved toward the interior so that its tip abuts the outer peripheral projecting surface 29 of the door 2 at a position closer to the interior side. A second waterproofing material 4 is attached to the exterior side of the door stopper 17, and the second waterproofing material 4 abuts the indoor projecting surface of the door 2. The first waterproofing material 3 and the second waterproofing material 4 are made of, for example, EPDM (ethylene propylene rubber). By providing a double layer of waterproofing materials 3, 4 between the vertical frames 13, 14 and the door 2 in this way, the waterproofing performance and airtightness performance of this fitting are improved.

As shown in FIG. 1, a heat foaming material 5 that foams and expands with the heat of a fire is provided on the outer periphery of the second tight material 4 on the inner peripheral projected surface 16 of the door end vertical frame 13 and the hanging vertical frame 14 along the longitudinal direction of the vertical frames 13, 14 over the entire length of the vertical frames 13, 14. Such a heat foaming material 5 can be appropriately selected from commercially available products, and for example, "Fi-Block" manufactured by Sekisui Chemical Co., Ltd. can be used. This is an organic fire-resistant material that utilizes plastic technology. Under normal conditions, it is in the form of a thin sheet, and when heated to 200°C or higher, it expands 5 to 40 times in the thickness direction, forming an insulating layer. It will not disappear in the event of a fire, and no harmful gases will be generated. Fi-Block also has an adhesive layer with a release paper on one side, so it can be easily attached by peeling off the release paper.

2, the upper frame 11 has a hollow portion 15 of approximately rectangular cross section on the exterior side, similar to the vertical frames 13 and 14, with an inner peripheral visible surface 16 extending toward the interior side beyond the hollow portion 15, and a door stop portion 17 protruding toward the interior side is formed at the interior end of the visible surface 16. A resin cover material 18 is attached to the interior side of the door stop portion 17.
A first tension member 3 is provided on the inner peripheral projecting surface 16 of the upper frame 11, which abuts against the projecting surface 29 of the door 2. A second tension member 4 is attached to the exterior side of the door stopper 17, and the second tension member 4 abuts against the interior projecting surface of the door 2.
A heated foaming material 19 is provided along the longitudinal direction of the upper frame 11 at a position adjacent to the indoor side of the first tight material 3 on the inner peripheral projecting surface 16 of the upper frame 11 over the entire length of the upper frame 11.

As shown in FIG. 2, the lower frame 12 has a door stop 17 that protrudes inward on the indoor side, and a weatherstripping material 20 is attached to the outdoor side of the door stop 17, which abuts against the indoor facing surface of the door 2. A plastic slip 21 is attached to the indoor side of the door stop 17, which covers the attachment portion of the weatherstripping material 20.

1 and 2, the door 2 has a so-called flush structure in which a U-shaped cross-section frame 22 is framed on all four sides, a heat insulating material 23 such as polystyrene foam boards is placed inside the frame, and steel plate panels 24, 25 are attached to the outside and inside of the door. The edges of the panels 24, 25 are bent forward and fixed to the frame 22 with rivets 26. The frame 22 is reinforced by placing a metal frame 22b inside the resin frame 22a.
As shown in Figure 3, the door 2 is attached to the hanging side vertical frame 14 with hinges 10 arranged at three places on the upper, lower and middle part of the hanging side. A handle 27 is attached to the middle part in the vertical direction on the door end side of the door 2, and a lock 28 is provided above and below the handle 27. The door is locked by engaging a deadbolt of the lock 28 (not shown) with a receiver provided on the door end side vertical frame 13.

As shown in Figure 1, on the projected surfaces 29 on the door tip and hanging side of the door 2, a heated foaming material 6 is provided along the longitudinal direction of the frame 22, adjacent to the outside side of the tip of the first tight material 3 that abuts against the door 2, over the entire length of the frame 22.
An edge material 30 made of an aluminum profile is attached to the front face 29 of the door 2. The edge material 30 has a smoke deflector 31 on the outside of the room, which hides the gap between the door front vertical frame 13 and the door 2 from the outside of the room.
As shown in FIG. 2, on the underside of the door 2, a heated foaming material 32 is provided along the longitudinal direction of the frame 22 at a position adjacent to the exterior side of the weatherstripping material 20, over the entire length of the frame 22.

Fig. 4 is a cross-sectional view of the fitting of the first embodiment, showing the state when a fire breaks out. Fig. 5 is a comparative example of the fitting of the first embodiment, showing the state when a fire breaks out when there is no heating foam material 6 on the projected surface 29 of the door end side and the hanging side of the door 2.
When a fire breaks out, the heat of the fire causes the door 2 to expand vertically, causing the heated surface to warp. The door 2's hanging side is restrained by the hinge 10 to the hanging side vertical frame 14, and the door end side is engaged at its vertical middle part with the door end vertical frame 13 by a lock 28, so the door end side warps more at the top and bottom.
As shown in Figure 4, in the event of a fire, the building fixture of this embodiment will have the heated foaming material 5 provided on the projected surfaces 16 of the vertical frames 13, 14 foam and expand in the space between the first tight material 3 and the second tight material 4, sealing the gap between the vertical frames 13, 14 and the door 2 from the inside of the room, and the heated foaming material 6 provided in the vicinity of the first tight material 3 on the projected surfaces 29 on the door end and hanging side of the door 2 foam and expand to seal the gap between the frame 1 and the projected surfaces 16, 29 of the door 2. Therefore, even if the door 2 warps due to heat and the upper and lower parts on the door end side move in the indoor/outdoor direction as shown in the figure, no gap will be created between the vertical frames 13, 14 and the door 2.
On the other hand, in the comparative example where there is no heating foaming material 6 on the projected surface 29 on the door tip side and hanging side of the door 2, when the door 2 warps due to heat and the upper and lower parts on the door tip side move in the indoor/outdoor direction, a gap 33 is created between the door tip side vertical frame 13, as shown in Figure 5. Note that no gap is created on the hanging side of the door 2 even if only the heating foaming material 5 is provided on the hanging side vertical frame 14.

In the case of a fire, the fitting of the first embodiment closes the gap between the upper frame 11 and the door 2 by foaming and expanding the heated foaming material 19 provided on the inner peripheral visible surface 16 of the upper frame 11. Also, the gap between the lower frame 12 and the door 2 closes by foaming and expanding the heated foaming material 32 provided on the underside of the door 2.
In this way, the building fixture of this embodiment has the gap between the frame 1 and the door 2 sealed on all four sides with heated foam materials 5, 6, 19, and 32, preventing flames and smoke from communicating between the inside and outside of the room through the gap between the frame 1 and the door 2, thereby demonstrating fire resistance.

Figures 6 to 8 show a second embodiment of the fitting according to the present invention (an embodiment of the invention according to claim 3). Like the first embodiment, this fitting is applied to an entrance door, and comprises a frame 1 that is attached to an opening in the building frame, and a door 2 that is attached to the frame 1 by means of hinges 10 so that it can be opened by pivoting to the outside of the room.

The door-end side vertical frame 13 and the hanging side vertical frame 14 are formed from aluminum shaped material, and as shown in Figure 6, have a door stop portion 17 that protrudes inwardly on the indoor side, and a weatherstripping material 7 is attached to the outdoor side of the door stop portion 17, and the weatherstripping material 7 abuts against the indoor facing surface of the door 2.
The first heating foaming material 8 is provided along the longitudinal direction on the inner peripheral projected surface 16 of the door end vertical frame 13 and the hanging side vertical frame 14, facing the indoor position of the projected surface 29 of the door 2. Furthermore, the second heating foaming material 9 is provided along the longitudinal direction on the inner peripheral projected surface 16 of the door end vertical frame 13 and the hanging side vertical frame 14, at a position on the indoor side of the first heating foaming material 8 and on the outer peripheral side of the tight material 7. As shown in FIG. 8, the first heating foaming material 8 is provided only on the upper and lower parts of the inner peripheral projected surface 16 of the door end vertical frame 13 and the hanging side vertical frame 14. The length of the first heating foaming material 8 at the upper and lower parts is 450 mm, respectively. On the other hand, the second heating foaming material 9 is provided over the entire length of the vertical frames 13 and 14.
As shown in Figure 6, a protrusion 34 is provided along the longitudinal direction on the inner projecting surface 16 of the door-end vertical frame 13 and the hanging-side vertical frame 14, and the indoor side edge of the first heated foaming material 8 and the indoor side edge of the second heated foaming material 9 can be positioned by abutting them against the protrusion 34, respectively. This makes it possible to easily and accurately attach the first heated foaming material 8 and the second heated foaming material 9.

The upper frame 11 is made of aluminum material, and as shown in FIG. 7, a door stop 17 is provided on the interior side, protruding inward, and a weatherstripping material 7 is attached to the exterior side of the door stop 17, which abuts against the interior facing surface of the door 2. A heated foam material 35 is provided along the entire length of the upper frame 11 at the outer periphery of the weatherstripping material 7 on the inner facing surface 16 of the upper frame 11.

The bottom frame 12 is made of aluminum material, and as shown in FIG. 7, a door stop 17 is provided on the interior side, protruding inward, and a weatherstripping material 7 is attached to the exterior side of the door stop 17, which abuts against the interior facing surface of the door 2. A resin slip 21 is attached to the interior side of the door stop 17, which covers the mounting portion of the weatherstripping material 7. A heated foam material 36 is provided along the entire length of the bottom frame 12 at the outer periphery of the weatherstripping material 7 on the inner facing surface 16 of the bottom frame 12, along the longitudinal direction of the bottom frame 12.

Fig. 9 is a cross-sectional view of the fitting of the second embodiment, showing the state when a fire occurs. Fig. 10 is a comparative example of the fitting of the second embodiment, showing the state when a fire occurs when the first heated foaming material 8 is not provided.
As shown in Figure 9, in the event of a fire, the building fixture of this embodiment causes the second heated foaming material 9 provided on the projected surface 16 on the outer periphery of the weatherstripping material 7 of the vertical frames 13, 14 to foam and expand, sealing the gap between the vertical frames 13, 14 and the door 2 from the inside of the room, and also causes the first heated foaming material 8 provided at the upper and lower parts on the outside of the room than the second heated foaming material 9 on the projected surface 16 of the vertical frames 13, 14 to foam and expand, sealing the gap between the vertical frames 13, 14 and the projected surfaces 16, 29 of the door 2. Therefore, even if the door 2 is thermally warped and the upper and lower parts on the door tip side move in the indoor/outdoor direction as shown in the same figure, no gap will be created between the vertical frames 13, 14 and the door 2.
On the other hand, in the comparative example without the first heating foaming material 8, when the door 2 is thermally warped and the upper and lower parts on the door end side move in the indoor/outdoor direction, a gap 33 is created between the door end vertical frame 13 as shown in Fig. 10. Note that the hanging side of the door 2 is restrained by the hinge 10, so no gap is created even with only the second heating foaming material 9. Therefore, in the second embodiment, the first heating foaming material 8 on the hanging side can be omitted.

In the second embodiment, the second heated foam material 9 can be provided on the visible surface of the vertical frames 13, 14 on the outer periphery of the door stopper 7 (for example, the exterior surface of the door stopper 17). In this case, the second heated foam material 9 on the visible surface is closer to the interior than the first heated foam material 8 on the visible surface. In the event of a fire, the second heated foam material 9 on the visible surface will foam and expand toward the exterior, pushing the first heated foam material 8 on the visible surface toward the exterior, thereby reliably sealing the gap between the door 2, which is bent toward the exterior, and the vertical frames 13, 14.

In the case of a fire, the fitting of the second embodiment closes the gap between the upper frame 11 and the door 2 by foaming and expanding the heated foaming material 35 provided on the inner peripheral visible surface 16 of the upper frame 11. In addition, the heated foaming material 36 provided on the inner peripheral visible surface 16 of the lower frame 12 closes the gap between the lower frame 12 and the door 2 by foaming and expanding.
In this way, the building fixture of this embodiment has the gap between the frame 1 and the door 2 sealed on all four sides with heated foaming materials 8, 9, 35, and 36, preventing flames and smoke from communicating between the interior and exterior of the room through the gap between the frame 1 and the door 2, thereby demonstrating fire resistance.

Figure 11 shows a third embodiment of the fitting according to the present invention (embodiment of the invention according to claim 3). Like the first embodiment, this fitting is applied to an entrance door, and is a parent-child door that includes a frame 1 that is attached to an opening in the building structure, and a parent door (door) 37 and a sub-door 38 that are attached to the frame 1 by hinges 10 so that they can be opened by rotating to the outside of the room.

The first heated foaming material 8 and the second heated foaming material 9 are provided on the inner peripheral projecting surfaces 16 of the left and right vertical frames 39, 39, as in the second embodiment.
An edge material (corresponding to the door-end vertical frame 13 in the second embodiment) 40 made of an aluminum shaped material is provided on the door end surface of the small door 38 over the entire height direction of the small door 38. The edge material 40 has a door stop portion 41 on the indoor side that protrudes toward the outer periphery of the small door 38. A weatherstripping material 7 is attached to the outdoor side surface of the door stop portion 41. The weatherstripping material 7 abuts against the indoor facing surface of the main door 37.
The first heating foaming material 8 is provided along the longitudinal direction on the projected surface 42 of the edge material 40 on the outer periphery of the small door, facing the projected surface 29 of the main door 37 at a position closer to the interior side. Furthermore, the second heating foaming material 9 is provided along the longitudinal direction on the projected surface 42 of the small door outer periphery of the edge material 40, at a position on the interior side of the room and on the outer periphery side of the tight material 7 than the first heating foaming material 8. As shown in FIG. 12, the first heating foaming material 8 is provided only on the upper and lower parts of the projected surface 42 of the edge material 40 on the outer periphery of the small door. The length of the first heating foaming material 8 at the upper and lower parts is 450 mm, respectively. On the other hand, the second heating foaming material 9 is provided over the entire length of the edge material 40.
The upper frame 11 and the lower frame 12 are provided with a weatherstripping material 7 and heat-foaming materials 35, 36, similar to the second embodiment shown in FIG.

Fig. 13 is a cross-sectional view of the fitting of the third embodiment, showing a state when a fire occurs. Fig. 14 is a comparative example of the fitting of the third embodiment, showing a state when a fire occurs when the first heated foaming material 8 is not provided.
In the case of the fittings of this embodiment, as shown in Fig. 13, in the event of a fire, the second heating foaming material 9 provided on the projected surface 42 on the outer periphery side of the tight material 7 of the edge material 40 of the small door 38 foams and expands to close the gap between the main door 37 and the small door 38 from the inside of the room, and the first heating foaming material 8 provided on the upper and lower parts of the projected surface 42 of the edge material 40 of the small door 38 foams and expands to close the gap between the projected surfaces of the main door 37 and the small door 38. Therefore, even if the main door 37 is thermally warped and the upper and lower parts of the door tip side move in the indoor/outdoor direction as shown in the figure, no gap will be created between the main door 37 and the small door 38. The gap between the hanging side of the main door 37 and the small door 38 and the vertical frames 39, 39 is closed by the first heating foaming material 8 and the second heating foaming material 9 that have foamed and expanded.
On the other hand, in the comparative example without the first heated foaming material 8, when the main door 37 is thermally warped and the upper and lower parts on the door edge side move in the indoor/outdoor direction, a gap 33 is created between the main door 37 and the edge material 40 of the small door 38, as shown in Fig. 14. Since the hanging sides of the main door 37 and the small door 38 are restrained by the hinges 10, no gap is created even with only the second heated foaming material 9. Therefore, in the third embodiment, the first heated foaming material 8 on the hanging side can be omitted.

In the third embodiment, the second heated foam material 9 can also be provided on the visible surface of the edge material 40 on the outer periphery of the tight material 7 (for example, the exterior surface of the door stop 41). In this case, since the second heated foam material 9 on the visible surface is closer to the interior than the first heated foam material 8 on the visible surface, in the event of a fire the second heated foam material 9 on the visible surface will foam and expand toward the exterior, pushing the first heated foam material 8 on the visible surface toward the exterior, thereby reliably sealing the gap between the main door 37 and the small door 38 that are bent toward the exterior.

Figure 15 shows a fourth embodiment of the fitting according to the present invention (an embodiment of the invention according to claim 4). Like the first embodiment, this fitting is applied to an entrance door, and comprises a frame 1 attached to an opening in the building frame, and a door 2 attached to the frame 1 by means of hinges 10 so that it can be opened by pivoting to the outside of the room. It differs from the first embodiment in that the frame 1 is provided with insulating properties by an insulating bridge material 45.

As shown in Figure 15, the door-end vertical frame 13 and the hanging-side vertical frame 14 are insulating profiles consisting of an exterior profile 43 and an interior profile 44 made of extruded aluminum alloy, and a resin insulating bridge material 45 connecting the exterior profile 43 and the interior profile 44.
A first tension material 3 that abuts against the projected surface 29 of the door 2 is provided at the indoor end position of the inner peripheral visible surface 16 of the outdoor side shape member 43. The indoor side shape member 44 has a door stop portion 17 that protrudes toward the indoor side, and a second tension material 4 that abuts against the indoor side visible surface of the door 2 is provided on the outdoor side surface of the door stop portion 17. A heating foaming material 5 that foams and expands due to the heat of a fire in the event of a fire is provided at the outer peripheral position of the second tension material 4 on the inner peripheral visible surface 16 of the indoor side shape member 44 along the longitudinal direction of the vertical frames 13, 14 over the entire length of the vertical frames 13, 14.
The upper frame (not shown), like the vertical frames 13, 14, is also an insulating profile consisting of an exterior profile 43 and an interior profile 44 made of extruded aluminum alloy, and a resin insulating bridge material 45 connecting the exterior profile 43 and the interior profile 44.

As shown in FIG. 15, on the projected surface 29 on the door end side and the hanging side of the door 2, a heated foaming material 6 is provided along the entire length of the frame 22 in the longitudinal direction of the frame 22, adjacent to the outdoor side of the tip of the first tight material 3 that abuts against the door 2.

The building fixture in this embodiment has insulating performance because the upper frame and vertical frames 13, 14 are made of insulating profiles consisting of an aluminum exterior profile 43 and an interior profile 44, and a resin insulating bridge material 45 connecting the exterior profile 43 and the interior profile 44.
Furthermore, in the same manner as in the first embodiment, in the event of a fire, the heated foaming material 5 provided on the projected surface 16 of the vertical frames 13, 14 will foam and expand in the space between the first tight material 3 and the second tight material 4, sealing the gap between the vertical frames 13, 14 and the door 2 from the inside of the room, and the heated foaming material 6 provided in the vicinity of the first tight material 3 on the projected surface 29 on the door end and hanging side of the door 2 will foam and expand, sealing the gap between the frame 1 and the projected surfaces 16, 29 of the door 2. Therefore, even if the door 2 warps due to heat and the upper and lower parts on the door end side move in the indoor/outdoor direction, no gap will be created between the vertical frames 13, 14 and the door 2 (see Figure 4).

Figure 16 shows a fifth embodiment of the fitting according to the present invention (an embodiment of the invention according to claim 5). Like the second embodiment, this fitting is applied to an entrance door, and comprises a frame 1 attached to an opening in the building frame, and a door 2 attached to the frame 1 by means of hinges 10 so that it can be opened by pivoting to the outside of the room. It differs from the second embodiment in that the frame 1 is provided with insulating properties by an insulating bridge material 45.

As shown in Figure 16, the door-end vertical frame 13 and the hanging-side vertical frame 14 are insulating profiles consisting of an exterior profile 43 and an interior profile 44 made of extruded aluminum alloy, and a resin insulating bridge material 45 connecting the exterior profile 43 and the interior profile 44.
A first heating foaming material 8 is provided along the longitudinal direction of the vertical frame 13 at the indoor end position of the inner peripheral projected surface 16 of the outdoor exterior shape member 43 of the door end vertical frame 13. The first heating foaming material 8 is provided so that the indoor edge coincides with the indoor edge of the inner peripheral projected surface 16 of the outdoor exterior shape member 43 and does not cover the insulating bridge 45. As in the second embodiment, the first heating foaming material 8 is provided only at the upper and lower parts of the entire length of the vertical frame 14 (see FIG. 8).
16, the interior side molded member 44 has a door stop portion 17 that protrudes toward the inner periphery, and a weatherstripping material 7 that abuts against the interior side visible surface of the door 2 is provided on the exterior side surface of the door stop portion 17. A second heating foaming material 9 that foams and expands due to the heat of a fire in the event of a fire is provided on the outer periphery side of the weatherstripping material 7 on the interior side visible surface 16 of the interior side molded member 44 along the longitudinal direction of the vertical frame 13 over the entire length of the vertical frame 13.
The hanging side vertical frame 14 is provided with only the second heating foaming material 9, and not with the first heating foaming material 8.
The upper frame (not shown), like the vertical frames 13, 14, is also an insulating profile consisting of an exterior profile 43 and an interior profile 44 made of extruded aluminum alloy, and a resin insulating bridge material 45 connecting the exterior profile 43 and the interior profile 44.

The building fixture in this embodiment has insulating performance because the upper frame and vertical frames 13, 14 are made of insulating profiles consisting of an aluminum exterior profile 43 and an interior profile 44, and a resin insulating bridge material 45 connecting the exterior profile 43 and the interior profile 44.
In addition, in the case of the fittings of this embodiment, as in the second embodiment, the second heating foaming material 9 provided on the outer peripheral side projected surface 16 of the weatherstripping material 7 of the vertical frames 13, 14 foams and expands in the event of a fire to close the gap between the vertical frames 13, 14 and the door 2 from the inside of the room, and the first heating foaming material 8 provided on the upper and lower parts of the inner peripheral side projected surface 16 outside the room from the insulating bridge material 45 of the door end vertical frame 13 foams and expands to close the gap between the door end vertical frame 13 and the projected surfaces 16, 29 of the door 2, so that even if the door 2 is thermally warped and the upper and lower parts of the door end side move in the indoor/outdoor direction, no gap is generated between the vertical frames 13, 14 and the door 2 (see FIG. 9). The first heating foaming material 8 is provided on the inner peripheral side projected surface 16 of the outdoor exterior shape material 43 so as not to cover the insulating bridge material 45, so that the first heating foaming material 8 can be easily attached and is not easily peeled off.

As described above, this fitting (first embodiment) comprises a frame 1 and a door 2, and the door 2 is opened and closed by rotating. The frame 1 has a first tightness material 3 that abuts against the visible surface 29 of the door 2, a second tightness material 4 that abuts against the visible surface of the door 2, and a heated foaming material 5 that foams in the space between the first tightness material 3 and the second tightness material 4 during a fire. The heated foaming material 6 is also provided near the first tightness material 3 on the opposite side of the second tightness material 4 from the first tightness material 3 on the visible surface 16, 29 of the frame 1 or the door 2, so that the gap between the frame 1 and the door 2 is blocked by the heated foaming materials 5, 6 during a fire, thereby achieving fireproof performance. The heated foaming material 6 is also provided near the first tightness material 3 on the visible surface 16, 29 of the frame 1 or the door 2 on the opposite side of the second tightness material 4 from the first tightness material 3, so that no gap is generated between the frame 1 and the door 2 even when the door 2 warps due to the heat of the fire during a fire.
In addition, since the frame 1 of this fitting (first embodiment) is made of aluminum, the frame 1 is less likely to deform or melt in the event of a fire, compared to a frame 1 made of resin, or a frame 1 whose exterior side is made of aluminum and whose interior side is made of resin, improving fire resistance. Moreover, the heated foaming material 5 that foams in the space between the first and second weatherstripping materials 3 and 4 in the event of a fire is provided on the projected surface 29 of the aluminum frame 1 facing the inner periphery, so that the heated foaming material 5 foams and expands quickly in the event of a fire to seal the gap between the frame 1 and the door 2, further improving fire resistance.

This fitting (first embodiment) comprises a frame 1 and a door 2, the door 2 rotates to open and close, the frame 1 has a weatherstripping material (first weatherstripping material) 3 that abuts against the projected surface 29 of the door 2 on the closing side in the opening and closing direction, and heated foaming materials 5, 6 that close the gap between the frame 1 and the projected surfaces 16, 29 of the door 2 in the event of a fire are provided on the opening side and closing side of the door 2 near the weatherstripping material 3, so that the gap between the frame 1 and the door 2 is closed by the heated foaming materials 5, 6 in the event of a fire, thereby achieving fire prevention performance. The heated foaming material 5 is also provided on the opening side of the door 2 near the weatherstripping material 3, so that no gap is created between the frame 1 and the door 2 even when the door 2 warps due to the heat of the fire in the event of a fire.
In addition, because the frame 1 of this fitting (first embodiment) is made of aluminum, the frame 1 is less likely to deform or melt in the event of a fire, improving fire resistance, compared to frames made of resin, or frames made of aluminum on the exterior side and resin on the interior side. Moreover, the heated foaming material 5 on the closing side of the door 2 near the weatherstripping material 3 is provided facing the inner periphery on the visible surface 16 of the aluminum frame 1, so that the heated foaming material 5 can foam and expand quickly in the event of a fire to seal the gap between the frame 1 and the door 2, further improving fire resistance.

This fitting (second and third embodiments) comprises a frame 1 and a door (door 2, main door 37), and the doors 2, 37 rotate to open and close. The frame (frame 1, edge material 40) has a weatherstripping material 7 that abuts the visible surface of the closing side of the door 2, 37 in the opening and closing direction, and a first heated foaming material 8 is provided on the frame 1, 40 or the visible surface of the door 2, 37 closer to the closing side of the door 2, 37, and a second heated foaming material 9 is provided on the visible surface or visible surface of the frame 1, 40 closer to the closing side of the door 2, 37 and on the outer periphery of the weatherstripping material 7 than the first heated foaming material 8, so that in the event of a fire the gap between the frame 1, 40 and the door 2, 37 is sealed by the first and second heated foaming materials 8, 9, thereby providing fire resistance. By providing a first heating foaming material 8 on the frame 1, 40 near the closing side of the door 2, 37 or on the prospective surface of the door 2, 37, no gap is generated between the frame 1, 40 and the door 2, 37 even when the door 2, 37 is warped by the heat of fire in the event of a fire.
Since the first heated foaming material 8 is provided on the upper and lower parts of the projected surface of the frame 1, 40 on the door end side or the door 2, 37, a small amount of heated foaming material 8 can effectively seal gaps caused by thermal warping of the door 2, 37.
When the second heated foaming material 9 is provided on the visible surface of the frame 1, 40 on the outer periphery of the door material 7, the second heated foaming material 9 foams and expands in the visible direction in the event of a fire, pushing the first heated foaming material 8, thereby more reliably sealing the gap between the door 2, 37 warped by heat and the frame 1, 40.
