[0009] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. Fig. 1 shows a hinged door 1 as a fixture. The hinged door 1 is, for example, a front door. The hinged door 1 is configured by fitting a main door 3 and a sub door 4 inside a frame body 2 provided at an opening of a building so that they can be opened and closed.

[0010] The main door 3 and the secondary door 4 are large enough to close half of the left and right width areas of the inner space of the frame 2. In the main door 3 and the secondary door 4, the left and right vertical frame 23 sides are referred to as the "hanging side", and the side opposite the hanging side is referred to as the "door end side". Furthermore, in the frame 2, the main door 3 and the secondary door 4, the surface arranged along the direction connecting the outside side X1 and the inside side X2 (the thickness direction of the main door 3 and the secondary door 4) is referred to as the "visible surface". The "up and down" direction in the hinged door 1 is the up and down direction along the vertical direction.

[0011] The frame body 2 is formed by framing a hollow upper frame 21, a lower frame 22, and left and right vertical frames 23 into a rectangular shape that conforms to the shape of the opening. As shown in Fig. 2, the main door 3 and the sub door 4 are placed inside the frame body 2 so that their door end faces 3a, 4a butt against each other in the left-right center. The main door 3 and the sub door 4 are opened inside the frame body 2 by rotating the door end side toward the outside side X1 around the axes of pivot hinges 31, 41 provided at the upper and lower parts of the hanging side, respectively, and closed inside the frame body 2 by rotating the door end side toward the inside side X2.

[0012] Handles 32, 42 extending in the vertical direction are provided on the door end sides of the main door 3 and the sub door 4, respectively. However, the shape of the handles 32, 42 is arbitrary and is not limited to a shape extending in the vertical direction. Concealed door closers 33, 43 are provided inside the upper part of the hanging side of the main door 3 and the sub door 4. Two locks 34, 34 arranged vertically and separately are attached inside the door end side of the main door 3. The locks 34, 34 are provided to lock and unlock between them and the door end surface 4a of the sub door 4.

[0013] An upper French drop 5 and a lower French drop 6 are provided inside the door end side of the sub-door 4. The upper French drop 5 is disposed at the upper part of the sub-door 4, and the lower French drop 6 is disposed at the lower part of the sub-door 4. The upper French drop 5 and the lower French drop 6 each have an operating portion 51, 61, fixing members 52, 62, and receiving brackets 53, 63.

[0014] The operating units 51, 61 are parts operated by the user when moving the fixing members 52, 62 up and down, and are disposed at the upper and lower parts, respectively, of the leading surface 4a of the sub-door 4. As shown in Figures 3 and 4, the operating units 51, 61 are attached to the leading surface 4a of the sub-door 4 with the operating surfaces 51a, 61a exposed to the leading surface 4a of the sub-door 4.

[0015] The fixing members 52, 62 are disposed adjacent to the door end surface 4a inside the sub-door 4. The fixing members 52, 62 have rods 521, 621 extending along the vertical direction of the sub-door 4, and connection parts 522, 622 that connect a lower end 521a of the rod 521 and an upper end 621a of the rod 621 to the operating parts 51, 61, respectively.

[0016] When the user operates the operating unit 51, 61, the rod 521, 621 moves up and down via the connecting portion 522, 622. In detail, when the rod 521, 621 is operated in the retracting direction by the operating unit 51, 61, the rod 521, 621 is completely accommodated inside the child door 4, and the upper end 521b and the lower end 621b of the rod 521, 621 do not protrude from the upper projected surface 4b and the lower projected surface 4c of the child door 4. When the rod 521, 621 is operated in the protruding direction by the operating unit 51, 61, the upper end 521b and the lower end 621b of the rod 521, 621 protrude from the upper projected surface 4b and the lower projected surface 4c of the child door 4 toward the upper frame 21 and the lower frame 22, respectively, as shown in FIG. 3 and FIG. 4.

[0017] The connecting parts 522, 622 are attached to the rods 521, 621 so as to connect the lower end 521a and the upper end 621a of the rods 521, 621 to the operating parts 51, 61. The connecting parts 522, 622 are made of metal rod-shaped or plate-shaped members. The connecting parts 522, 622 extend from the lower end 521a and the upper end 621a of the rods 521, 621 toward the operating parts 51, 61, and are fixed to the movable parts 511, 611 of the operating parts 51, 61 by bolts 512, 612. As a result, the rods 521, 621 are attached to the operating parts 51, 61 so as to be offset from the door end surface 4a toward the hanging side (left side in Figs. 3 and 4) by an amount corresponding to the length of the connecting parts 522, 622. The offset amount of the rods 521, 621 by the connecting portions 522, 622 corresponds to the positions of the recesses 531, 631 of the receiving fittings 53, 63 which will be described later.

[0018] The receiving bracket 53 of the upper French drop 5 is attached to the lower surface 21a of the upper frame 21 so as to face the upper visible surface 4b on the door edge side of the sub-door 4. The receiving bracket 63 of the lower French drop 6 is attached to the upper surface 22a of the lower frame 22 so as to face the lower visible surface 4c on the door edge side of the sub-door 4. The receiving brackets 53, 63 have recesses 531, 631 that receive upper end portions 521b and lower end portions 621b of the rods 521, 621 protruding from the sub-door 4, and flange portions 532, 632 that extend outward from the periphery of the recesses 531, 631.

[0019] The configuration of the receiving brackets 53, 63 will be described in further detail with reference to the receiving bracket 63 shown in Figures 5, and 8 to 10. Figures 5, and 8 to 10 show the receiving bracket 63 attached to the lower frame 22. The receiving bracket 53 attached to the upper frame 21 has the same configuration as this receiving bracket 63, and therefore the description of the configuration of the receiving bracket 63 shown in Figures 5, and 8 to 10 also applies to the description of the configuration of the receiving bracket 53.

[0020] The recesses 531, 631 of the receiving brackets 53, 63 have a rectangular shape that is long in the left-right length direction of the upper frame 21 and the lower frame 22 in a plan view. The flanges 532, 632 extend outward around the four peripheries of the rectangular recesses 531, 631, but extend longer in the direction along the length direction of the upper frame 21 and the lower frame 22 than in the direction along the indoor-outdoor direction of the upper frame 21 and the lower frame 22. As a result, screw fastening portions 532a, 532a, 632a, 632a are formed on both the left and right sides of the recesses 531, 631. The receiving brackets 53, 63 are fixed to the lower surface 21a of the upper frame 21 and the upper surface 22a of the lower frame 22 by screws 533, 633 at the screw fastening portions 532a, 532a, 632a, 632a, respectively.

[0021] As shown in Fig. 5, in a plan view, position P1 of edges 532b, 632b of the receiving metal fittings 53, 63 arranged closest to the parent door 3 is arranged at a position shifted toward the hanging end side of the child door 4 from position P0 of the door end surface 4a of the child door 4. As a result, the receiving metal fittings 53, 63 are not exposed at all from the door end surface 4a of the child door 4 to the parent door 3 side, and are arranged completely hidden by the upper visible surface 4b and the lower visible surface 4c of the child door 4. Therefore, as shown in Figs. 6 and 7, the receiving metal fittings 53, 63 cannot be seen by people passing by the parent door 3 side.

[0022] 8, the screw fastening portions 532a, 632a of the receiving fittings 53, 63 may be provided only on the flange portions 532, 632 extending from the recesses 531, 631 toward the hanging side of the child door 4. The flange portions 532, 632 of the receiving fittings 53, 63 extend farther toward the hanging side of the child door 4 than the parent door 3 side, forming the screw fastening portions 532a, 632a into which the screws 533, 633 are driven.

[0023] According to this, the extension amount of the flange portion 532, 632 arranged on the parent door 3 side of the recessed portion 531, 631 can be kept to a necessary minimum, or the flange portion 532, 632 itself can be prevented from extending, so that the edge 532b, 632b on the parent door 3 side of the receiving metal fitting 53, 63 can be brought closer to the door end surface 4a of the child door 4. As a result, the receiving metal fitting 53, 63 can make the distance L between the recessed portion 531, 631 and the door end surface 4a of the child door 4 smaller than that of the receiving metal fitting 53, 63 shown in Fig. 5. Since the offset amount of the rod 521, 621 can be reduced by shortening the connecting portion 522, 622, the rod 521, 621 can be moved up and down more smoothly when the operating portion 51, 61 is operated.

[0024] The screw fastening portions 532a, 632a of the receiving fittings 53, 63 may be provided only on the flange portions 532, 632 extending from the recesses 531, 631 to at least one of the outdoor side X1 and the indoor side X2. Fig. 9 shows an example in which the screw fastening portions 532a, 632a are provided on both of the flange portions 532, 632 extending from the recesses 531, 631 to the outdoor side X1 and the indoor side X2. The flange portions 532, 632 extend farther in the indoor / outdoor direction than in the left-right length direction of the upper frame 21 and the lower frame 22, forming the screw fastening portions 532a, 632a into which the screws 533, 633 are driven.

[0025] In this case, as in the case of the receiving bracket 53, 63 shown in Fig. 8, the extension amount of the flange portion 532, 632 arranged on the parent door 3 side of the recess 531, 631 can be kept to a necessary minimum, or the flange portion 532, 632 itself can be prevented from extending. In this case, too, the end edge 532b, 632b on the parent door 3 side of the receiving bracket 53, 63 can be brought closer to the door end surface 4a of the child door 4, so that the distance L between the recess 531, 631 and the door end surface 4a of the child door 4 can be made smaller than that in the case of the receiving bracket 53, 63 shown in Fig. 5. The receiving bracket 53, 63 shown in Fig. 9 is screwed to the upper frame 21 and the lower frame 22 on both sides of the recess 531, 631, so that the fixed state of the receiving bracket 53, 63 is stable, as in the case of the receiving bracket 53, 63 shown in Fig. 5.

[0026] As shown in Fig. 10, the receiving metal fittings 53, 63 may have screw fastening portions 531a, 631a into which screws 533, 633 are driven inside the recesses 531, 631. Fig. 10 shows an example in which the screw fastening portions 531a, 631a are formed at the bottoms of the recesses 531, 631, but the screw fastening portions 531a, 631a may be formed on the side surfaces of the recesses 531, 631, for example.

[0027] In this receiving metal fitting 53, 63, the flange portion 532, 632 extending in any direction around the recessed portion 531, 631 can be limited to the minimum extension amount, or the flange portion 532, 632 itself can be prevented from extending, so that the end edge 532b, 632b on the parent door 3 side of the receiving metal fitting 53, 63 can be brought closer to the door end surface 4a of the child door 4. In addition to being able to reduce the distance L between the recessed portion 531, 631 and the door end surface 4a of the child door 4, since the screws 533, 633 are not arranged in the flange portion 532, 632, the receiving metal fitting 53, 63 can be made less noticeable when the child door 4 is opened. The receiving metal fitting 53, 63 can be stably fixed to the upper frame 21 and the lower frame 22 with the minimum number of screws 533, 633 required.

[0028] The hinged door 1 as the fitting of the present embodiment described above provides the following advantages.

[0029] (1) A hinged door 1 having a frame body 2 attached to an opening, a parent door 3 and a child door 4 that are placed inside the frame body 2 with their door end faces 3a, 4a butted together so as to be able to be opened and closed, and a French stop (upper French stop 5, lower French stop 6) for fixing the child door 4, wherein the French stops 5, 6 have fixing members 52, 62 (rods 521, 621) that are arranged so as to be able to move up and down inside the door end side of the child door 4, and receiving brackets 53, 63 that receive the ends (upper end 521b, lower end 621b) of the fixing members 52, 62 protruding from the child door 4, and the positions of the edges 532b, 632b of the receiving brackets 53, 63 on the parent door 3 side are arranged closer to the hanging side of the child door 4 than the position of the door end face 4a of the child door 4.

[0030] According to this, the entirety of the receiving metal fittings 53, 63 are arranged completely hidden on the side of the hanging end of the child door 4 from the door end surface 4a of the child door 4, so the receiving metal fittings 53, 63 are not exposed from the door end surface 4a of the child door 4 to the parent door 3 side and are not visible to people passing by the parent door 3 side. Therefore, the appearance of the hinged door 1 is not impaired for people passing by the parent door 3 side, and the design is improved.

[0031] (2) In the above (1), the receiving bracket 53, 63 has a recess 531, 631 that accommodates the end (upper end 521b, lower end 621b) of the fixing member (rod 521, 621), and a flange portion 532, 632 extending outward from the recess 531, 631, and the receiving bracket 53, 63 has a screw-fastening portion 532a, 632a only on the flange portion 532, 632 extending from the recess 531, 631 toward the hanging side of the sub-door 4.

[0032] According to this, the extension amount of the flange parts 532, 632 arranged on the parent door 3 side of the recessed parts 531, 631 can be kept to a necessary minimum, or the flange parts 532, 632 themselves can be prevented from extending, so that the edge 532b, 632b on the parent door 3 side of the receiving metal fittings 53, 63 can be brought closer to the door end surface 4a of the child door 4. This makes it possible to reduce the distance L between the recessed parts 531, 631 of the receiving metal fittings 53, 63 and the door end surface 4a of the child door 4, so that the connecting parts 522, 622 can be shortened to reduce the offset amount of the rods 521, 621, and the rods 521, 621 can be moved up and down more smoothly.

[0033] (3) In the above (1), the receiving bracket 53, 63 has a recess 531, 631 that accommodates the end (upper end 521b, lower end 621b) of the fixing member (rod 521, 621) and a flange portion 532, 632 extending outward from the recess 531, 631, and the receiving bracket 53, 63 has a screw-fastening portion 532a, 632a only on the flange portion 532, 632 extending from the recess 531, 631 to at least one of the outside side X1 and the inside side X2.

[0034] According to this, the extension amount of the flange parts 532, 632 arranged on the parent door 3 side of the recessed parts 531, 631 can be kept to a necessary minimum, or the flange parts 532, 632 themselves can be prevented from extending, so that the edge 532b, 632b on the parent door 3 side of the receiving metal fittings 53, 63 can be brought closer to the door end surface 4a of the child door 4. This makes it possible to reduce the distance L between the recessed parts 531, 631 of the receiving metal fittings 53, 63 and the door end surface 4a of the child door 4, so that the connecting parts 522, 622 can be shortened to reduce the offset amount of the rods 521, 621, and the rods 521, 621 can be moved up and down more smoothly. When screw fastening portions 532a, 632a are provided on both the outdoor side X1 and the indoor side X2 of the recesses 531, 631, the receiving brackets 53, 63 are screwed to the upper frame 21 and the lower frame 22 on both sides of the recesses 531, 631, so that the fixed state of the receiving brackets 53, 63 is stable.

[0035] (4) In the above (1), the receiving metal fittings 53, 63 have screw fastening portions 531a, 631a inside the recesses 531, 631.

[0036] According to this, the extension amount of the flange portion extending around the recessed portion 531, 631 can be kept to the minimum necessary, or the flange portion itself can be prevented from extending around, so that the end edge 532b, 632b on the parent door 3 side of the receiving metal fitting 53, 63 can be brought closer to the door end surface 4a of the child door 4. This makes it possible to further reduce the distance L between the recessed portion 531, 631 of the receiving metal fitting 53, 63 and the door end surface 4a of the child door 4, so that the connecting portion 522, 622 can be shortened to reduce the offset amount of the rod bar 521, 621, and the rod bar 521, 621 can be moved up and down more smoothly. Since no screw is arranged on the flange portion, the receiving metal fitting 53, 63 can be made less noticeable when the child door 4 is opened. The receiving metal fitting 53, 63 can be stably fixed to the upper frame 21 and the lower frame 22 with the minimum number of screws 533, 633 required.

[0037] In the above embodiment, the rods 521, 621 are exemplified as the fixing members 52, 62 provided on the upper French drop 5 and the lower French drop 6, but the present invention is not limited thereto. The fixing members 52, 62 that are provided so as to be movable up and down by the operation of the operation parts 51, 61 may be, for example, members formed in a plate shape.

[0038] The operating parts of the upper French drop 5 and the lower French drop 6 are not limited to being operated by the user, but may be configured to unlock the child door 4 in conjunction with the opening operation of the parent door 3.

[0039] The offset structure of the rods 521, 621 is not limited to the structure described above, and may be such that, for example, the connection parts 522, 622 and the movable parts 511, 611 of the operation parts 51, 61 are integrally formed.

[0040] In the above embodiment, an upper French stopper 5 and a lower French stopper 6 are provided at the upper and lower parts, respectively, of the leading edge of the sub-door 4, but a French stopper may be provided at only one of the upper and lower parts, respectively, of the leading edge of the sub-door 4.
