The distance x2 between the upper surface 35d of the receiving plate portion 35b and the lower edge 33e of the sagging prevention member 33 is larger than the interval x1 between the upper surface 35d of the receiving plate portion 35b and the lower end of the roller 34. For this reason, even if the door 20 is opened and closed in a state where the door 20 is normally attached to the frame body 10, the sagging prevention member 33 and the roller 34 do not come into contact with the receiving plate portion 35b.

  Such joinery 1 is exposed to a flame due to a fire or the like, and for example, the synthetic resin frame body 10 positioned between the hinge 17 supporting the door 20 and the frame reinforcing member 15 is softened or melted. As a result, a gap is generated between the hinge 17 and the frame reinforcing member 15, and the door end side of the door 20 may hang down. At this time, if the door 20 is in a closed state, the roller 34 provided at the lower end on the door-end side is brought into contact with the door 20 to prevent the door-end side from drooping. Even if the synthetic resin roller 34 is melted by the heat of the flame, the lower edge 33e of the sag prevention member 33 abuts on the upper surface 35d of the receiving member 35 to support the door 20. It is possible to prevent the front side from sagging. For this reason, even if the fitting 1 is exposed to a flame, there is no gap that penetrates the interior and the exterior.

  On the other hand, when the door 20 is opened, some external force is applied, the door tip side of the door 20 hangs down, and the lower edge 33e of the sag prevention member 33 is below the upper surface 35d of the receiving member 35 as shown in FIG. Even when the door 20 is closed, when the door 20 is closed, after the roller 34 comes into contact with the inclined portion 35c of the receiving member, the surface of the roller 34 rolls to smoothly move the door 20 to a position facing the lower frame 14. The door 20 is configured to be moved and closed. At this time, since the roller 34 is made of a synthetic resin, even if it contacts with the iron receiving member 35, the generation of metal sound can be suppressed.

  The vertical frame 12 on the door end side is provided with the above-described regulating member 50 that regulates the downward movement of the frame reinforcing member 15 provided on the vertical frame 12 in a state where the frame body 10 is fixed to the housing 2. It has been.

  As shown in FIG. 16, the regulating member 50 is disposed in the vertical groove 12 g and the horizontal groove 14 g provided to be connected to the right vertical frame 12 of the frame body 10, that is, the vertical frame 12 and the lower frame 14 on the door end side. Has been. In FIG. 16, the frame body 10 is partially broken in order to make the state of the regulating member 50 easier to see.

  The regulating member 50 is a metal member, for example, an iron member, having a width slightly narrower than the width of the vertical groove portion 12g and the horizontal groove portion 14g. As shown in FIGS. 14 and 17, the restricting member 50 is fixed to the lower end 15c side of the frame reinforcing member 15 provided in the vertical frame 12 on the door end side by the screw 40 via the outer peripheral side wall portion 12c. The fixed portion 51, the downwardly extending portion 52 extending downward from the frame side fixed portion 51, and the casing facing the casing 2 extending in the direction of finding from the lower edge of the downward extending portion 52 and facing the lower casing 2 Part 53.

  The downward extending portion 52 connected to the frame side fixing portion 51 that is in contact with the bottom of the vertical groove portion 12g extends toward the open end 12i side of the vertical groove portion 12g on the upper end side, and the vertical groove portion 12g. The vertical groove portion 12g is connected to the horizontal groove portion 14g so as to extend along the open end 12i from the portion reaching the open end 12i. That is, the housing facing portion 53 that faces the lower housing 2 is positioned on the open end 14 i side of the lateral groove portion 14 g that is recessed in the outer peripheral surface 14 f placed on the housing 2 in the lower frame 14. Therefore, when the frame body 10 is placed on the placement surface 2a of the housing 2, the housing-facing portion 53 is in contact with or placed close to the placement surface 2a of the lower housing 2. It arrange | positions so that it may oppose.

  That is, in the regulating member 50 in which the frame side fixing portion 51 on the upper end side is fixed to the frame reinforcing member 15, the housing facing portion 53 on the lower end side is in contact with or close to the mounting surface 2 a of the lower housing 2. Since they face each other, even when the frame reinforcing member 15 moves downward, the restriction member 50 is brought into contact with the mounting surface 2a of the lower housing 2 and the downward movement is restricted. . Here, when the housing facing portion 53 of the regulating member 50 fixed to the frame reinforcing member 15 is not in contact with the mounting surface 2a of the lower housing 2, the housing facing portion 53 and the mounting surface 2a The interval is set to be smaller than the vertical width in which the upper frame 13 and the upper collar 24 overlap in the prospective direction.

  According to the fitting 1 of this embodiment, the drooping prevention member 33 provided on the door rod 23 of the door 20 is in a state where the door 20 closes the opening formed by the frame body 10, and the door tip of the door 20. When the side hangs down, the sag preventing member 33 is brought into contact with the receiving member 35 provided in the frame body 10, so that it is possible to prevent the door 20 from hanging down. At this time, the eaves reinforcing member 27 to which the sagging prevention member 33 is fixed is provided in the door-end eaves 23, and the frame reinforcing member 15 to which the receiving member 35 is fixed is provided in the right vertical frame 12. Therefore, the lower frame 14 and the lower collar 25 are not provided with the sag prevention member 33 and the receiving member 35. For this reason, the lower frame 14 and the lower rod 25 are not required to have strength for supporting the door 20, and it is not necessary to provide the rod reinforcing member 27, the frame reinforcing member 15 and the like. It is possible to reduce. Therefore, it is possible to provide the joinery 1 capable of preventing the door 20 from hanging down while suppressing the weight and cost.

  Further, the frame reinforcing member 15, the heel reinforcing member 27, the sag prevention member 33, and the receiving member 35 provided in the right vertical frame 12 and the hollow portions 12 a, 23 a, and 23 b of the door-end 框 23 are all non-combustible. Since the sag prevention member 33 is fixed to the heel reinforcement member 27 and the receiving member 35 is fixed to the frame reinforcement member 15, the door 20 even if the fitting 1 is exposed to a flame or the like and is heated. It is possible to maintain a state in which the opening is closed by the door 20 without hanging down.

  Further, since the sag prevention member 33 faces the receiving member 35 with a gap in the vertical direction when the door 20 does not hang down, the door 20 does not hang down, that is, the door 20 is normally attached. In this state, it can be opened and closed smoothly without contacting the frame 10 or the like.

  When the door 20 is closed in a state where the opening is opened and the lower edge 33e of the sag prevention member 33 hangs down so as to be positioned below the receiving member 35, the sag prevention member 33 is below the lower edge 33e of the sag prevention member 33. The lower end of the positioned roller 34 comes into contact with the receiving member 35 first. For this reason, since the sag prevention member 33 is prevented from contacting the receiving member 35 by the roller 34, even if the door 20 hangs down, the sag prevention member 33 is brought into contact with the receiving member 35 when the door 20 is closed. The door 20 can be smoothly closed.

  Further, since the roller 34 is made of a synthetic resin, when the roller 34 and the receiving member 35 come into contact with each other, the roller 34 rolls on the receiving member 35 so that the door 20 can be closed more smoothly. is there.

  Moreover, since the door 20 in which the multilayer glass 26 is provided on the inner peripheral side of the housing 21 has a large ratio of the weight of the multilayer glass 26 to the total weight, the door 20 is rotatably supported by the frame body 10. Since the hinge 17 and the sag prevention member 33 are provided on opposite sides of the double-glazed glass 26 in the prospective direction, the door 20 can be supported in a more stable state.

  In the said embodiment, although the roller 34 was provided in the drooping prevention member 33 as a guide member, the example was shown, but it does not restrict to this. For example, as shown in FIG. 11, a synthetic resin cap 36 that covers the tip of the sag prevention member may be provided. Further, as shown in FIG. 12, a bent guide portion 33 f obtained by bending the lower end portion of the sag preventing member 33 may be provided so that the edge 33 g of the lower extending portion 33 c does not contact the receiving member 35. Further, the guide member is not necessarily provided if it only prevents the drooping due to a fire and it is not necessary to open and close after the drooping.

  Moreover, in the said embodiment, although the sagging prevention member 33 was demonstrated in the example provided in the groove part 23i of the door rod 23, you may provide in the outer side of a groove part. At this time, as shown in FIG. 13, the sagging prevention member may have a shape in which the fixing portion 33h that is in contact with the inner peripheral wall portion 23k forming the outer hollow portion 23a extends downward as it is.

  In the frame 10 provided in the joinery 1 of the present embodiment, the vertical frames 11 and 12 and the horizontal frames 13 and 14 have ends 11h, 12h, 13h, and 14h that are cut so that the cut ends form 45 degrees. Since they are welded together, the frame reinforcing member 15 accommodated in the hollow portions 11 a and 12 a of the vertical frames 11 and 12 cannot be arranged up to the end of the frame body 10. For this reason, the frame reinforcement member 15 provided in the vertical frame 13 is located in a state of being separated upward from the placement surface 2a of the housing 2 on which the frame body 10 is placed. And since the regulating member 50 which protrudes below the said frame reinforcement member 15 and regulates the downward movement of the frame reinforcement member 15 is being fixed to the frame reinforcement member 15, the downward direction of the frame reinforcement member 15 is fixed. The movement is restricted, and it is possible to maintain the state in which the sag preventing member 33 contacts the receiving member 35 fixed to the frame reinforcing member 15 and supports the door 20.

  The joinery 1 includes a sag prevention member 33 on the door toe 23, and even if the receiving member 35 of the sag prevention member 33 is fixed to the frame reinforcing member 15 and is heated by being exposed to a flame or the like, the door 20 hangs down. It is configured to maintain the state where the opening made by the frame body 10 is closed by the door 20, but when the frame reinforcing member 15 moves downward, the door toe 23 side of the door 20 is lowered. There is a possibility that a through-hole may be formed on the door 20. For example, when the joinery 1 is exposed to a flame, the frame reinforcing member 15 is heated, and there is a risk that thermal expansion is generated such that the lower end 15c of the frame reinforcing member 15 moves downward. As described above, even when the frame reinforcing member 15 is thermally stretched, the fitting 1 according to the present embodiment is configured such that the regulating member 50 fixed to the frame reinforcing member 15 is brought into contact with the mounting surface 2a of the frame 2 and the frame 2 When the downward movement of the reinforcing member 15 is restricted, the door 20 does not hang down. For this reason, it is possible to maintain the state in which the opening is closed by the door 20. In particular, the restricting member 50 restricts the downward movement of the frame reinforcing member 15 by coming into contact with the mounting surface 2a of the frame 2 on which the frame body 10 is placed. It is possible to restrict the downward movement of 15.

  Further, since the frame reinforcing member 15 is also fixed to a portion of the housing 2 adjacent to the vertical frame 12 on the door-end side by the frame fixing bracket 16, the downward movement of the frame reinforcing member 15 is more reliably regulated. Is possible. In addition, since the regulating member 50 and the frame fixing bracket 16 are fixed to the frame reinforcing member 15 with a single screw 40, the fitting 1 having a low cost and excellent workability can be obtained by reducing the number of screws 40 and the number of mounting steps. It is possible to provide.

  In addition, since the regulating member 50 is provided in the longitudinal groove portion 12g of the longitudinal frame 12 and the lateral groove portion 14g of the lower frame 14 which are formed to be slightly wider than the regulation member 50 and are connected to each other. The regulating member 50 is guided by the longitudinal groove portion 12g and the lateral groove portion 14g. For this reason, even if the door 20 hangs down and is supported by the frame reinforcing member 15, the restricting member 50 is connected to the frame reinforcing member 15, so that the frame reinforcing member 15 is reliably twisted without being twisted. 20 can be supported.

  In the above embodiment, the casing facing portion 53 of the regulating member 50 is configured to have a flat plate shape extending in the horizontal direction. However, as shown in FIG. It is good also as a structure which has the bending part 54 bent to the inward side of the horizontal groove part 14g, ie, the bottom part side. In this case, the frame reinforcing member 15 can be more reliably supported by being further guided in the lateral groove portion 14g.

  Moreover, in the said embodiment, the downward extension part 52 connected with the frame side fixing | fixed part 51 has the inclination part 52a extended toward the open end 12i side of the vertical groove part 12g in the upper end side. Yes. This is because the welded portion between the vertical groove portion 12g and the horizontal groove portion 14g generates burrs due to welding inside, so that the burr is cut off and the regulating member 50 is provided. At this time, burrs are less likely to be removed on the inner side of the open ends 12i and 14i of the vertical groove portion 12g and the horizontal groove portion 14g, and the burrs may remain. The burrs remaining in the vertical groove portion 12g and the horizontal groove portion 14g may interfere with the regulating member 50. For this reason, in order to arrange the regulating member 50 on the open ends 12i and 14i side of the longitudinal groove portion 12g and the lateral groove portion 14g, an inclined portion 52a is provided. However, if the burr can be cut to the bottom side of the longitudinal groove portion 12g and the lateral groove portion 14g. 18 (b) and FIG. 18 (c), the frame-side fixing portion 51 is vertically extended, and the regulating member 50 including the frame-side fixing portion 51 and the housing facing portion 53, or the frame-side fixing. The restriction member 50 may be composed of the part 51, the housing facing part 53, and the bent part 54. Further, as shown in FIG. 18D, the restricting member 50 may have a plate shape in which the frame side fixing portion 51 extends downward.

  In the above embodiment, the frame reinforcing member 15, the heel reinforcing member 27, the sag preventing member 33, the receiving member 35, and the regulating member 50 are all made of nonflammable iron, but the present invention is not limited thereto, and is flame retardant. Alternatively, any nonflammable member may be used. Further, when fire resistance is not required, any member having higher rigidity and strength than the synthetic resin constituting the frame and the casing may be used.

  In the said embodiment, although the example which was set as the laminated glass 26 which formed two glass plates facing each other at intervals and was integrally formed was demonstrated in the said embodiment, glass is a single plate or 3 or more plate glass. They may be formed integrally with each other facing each other at an interval. Moreover, the combination of the plate glass which comprises glass material is not restricted to the low reflection glass and netted glass as shown in FIG. 2, The structure containing float glass may be sufficient.

  In the said embodiment, although the frame reinforcement member 15 demonstrated the example fixed to the housing 2 via the metal frame fixing metal fitting 16, the frame reinforcement member 15 is not via a metal member, It may be fixed to a flame-retardant or non-flammable housing.

  In addition, 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.
