[0007] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. A description will be given of a fitting 1 according to one embodiment. In this specification, the "visible direction" refers to the face direction of the surface material of the fitting 1 placed in an opening formed in the wall of a building, and the "visible direction" refers to the thickness direction of the surface material (i.e., the depth direction). The "visible direction" also refers to the indoor / outdoor direction. The "visible surface" refers to the surface of the fitting 1 facing the outside and the inside of the room, respectively, and the "visible surface" refers to the surface of the fitting 1 extending in the indoor / outdoor direction. In the drawings, the outdoor side of the fitting 1 is referred to as the outdoor side X1, and the indoor side of the fitting 1 is referred to as the indoor side X2. The "horizontal direction" of the outer shoji screen 5 is also referred to as the left-right direction.

[0008] As shown in Figures 1 and 2, the building fixture 1 comprises a frame body 2 attached to an opening in a building frame (not shown), a post 3 arranged within the frame body 2, a FIX section 4 arranged on the indoor side X2 within the frame body 2 on one side of the post 3 in the left-right direction, an outer shoji screen 5 arranged on the outdoor side X1 within the frame body 2 on the other side of the post 3 in the left-right direction and movable in the left-right direction, and a pleated screen 58 (retractable screen) arranged on the indoor side X2 within the frame body 2 on the other side of the post 3 in the left-right direction so as to be retractable.

[0009] The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape.

[0010] As shown in Figure 1, the mullion 3 is arranged extending vertically at a midpoint in the left-right direction on the indoor side X2 of the frame body 2. The opening of the frame body 2 is divided into left and right parts midway in the left-right direction by the mullion 3. As a result, on the indoor side X2 of the frame body 2, a FIX section 4 is formed on one side in the left-right direction of the frame body 2, and an opening 25 that is opened and closed by an outer screen 5 is formed on the other side in the left-right direction of the frame body 2.

[0011] As shown in Figures 1 and 2, the FIX section 4 is configured by fixing a glass panel 41 as a surface material to the mullion 3 and the frame body 2 on one side in the left-right direction (the right side in Figures 1 and 2) of the mullion 3 within the frame body 2. The FIX section 4 is a fixed window that cannot be opened or closed.

[0012] The outer shoji screen 5 is a shoji screen that can be opened and closed by sliding left and right (horizontally) within the frame body 2 on the outside X1 of the frame body 2. The outer shoji screen 5 is configured to be able to open and close an opening 25 formed on the other side of the FIX section 4 (the left side in Figures 1 and 2).

[0013] The outer shoji screen 5 is constructed by fitting a glass panel 55 around the inner periphery of a rectangular frame body 50 made up of an upper frame (not shown), a lower frame 52, a vertical frame 53 located at the front of the door, and a vertical frame 54 located at the rear of the door.

[0014] 2, the vertical stile 53 arranged on the door end side has a vertical stile main body 531 and a resin material 532. The end of the face material 55 on the vertical stile 53 side is sandwiched and held between the vertical stile main body 531 and the resin material 532.

[0015] As shown in Figures 1 to 6, a handle 7 is attached to the visible surface 533 of the vertical frame 53 located on the door edge side. The handle 7 is attached to the visible surface 533 on the inner circumferential side in the left-right direction of the resin material 532 of the vertical frame 53, on the indoor side X2 of the surface material 55 of the outer shoji screen 5, by the handle structure 6 for fittings.

[0016] As shown in FIG. 4, a vertical frame side locking portion 26 and an anti-emptying piece pushing portion 27 are provided on the visible surface 231 of the vertical frame 23 on the door end side of the frame body 2.

[0017] The vertical-frame-side locking portion 26 is provided on the visible surface 231 of the vertical frame 23 of the frame body 2. The vertical-frame-side locking portion 26 is formed in a box shape and has an opening 261 that opens toward the inner periphery in the left-right direction of the frame body 2, a hook accommodating portion 262 that communicates with the opening 261, and a lower locking wall 263 that stands below the opening 261 and in front of the hook accommodating portion 262 so as to protrude upward.

[0018] The lower locking wall 263 has a thickness in the left-right direction and is formed in a plate shape that extends in the up-down direction and the indoor-outdoor direction. A hook portion 92 (described later) of the interlocking mechanism 9 is engaged with the upper end of the lower locking wall 263 when the handle 7 is locked, and the hook portion 92 of the interlocking mechanism 9 is released from the engagement when the handle 7 is unlocked.

[0019] The empty-hanging prevention piece pushing-in portion 27 is provided on the visible surface 231 of the vertical frame 23 of the frame body 2, below the vertical frame side locking portion 26. The empty-hanging prevention piece pushing-in portion 27 is formed in a box shape that protrudes from the visible surface 231 of the vertical frame 23.

[0020] As shown in Figures 5 and 6, the handle structure 6 for fittings comprises a handle 7, a handle mechanism 8 connected to the handle 7, and an interlocking mechanism 9 connected to the handle mechanism 8. The handle 7 is attached to a vertical frame 53 located on the door end side via the handle mechanism 8. The interlocking mechanism 9 is connected to the handle 7 by being connected to the handle mechanism 8.

[0021] The handle 7 can be locked or unlocked by moving it up and down (in the forward direction). When the handle 7 is moved downward, it is placed in the locked position (see Figure 5), and when it is moved upward, it is placed in the unlocked position (see Figure 6). The handle 7 is made of metal.

[0022] The locked position of the handle 7 is a position where the hook portion 92 of the interlocking mechanism 9 is engaged with the lower engaging wall 263 of the vertical frame-side engaging portion 26 arranged on the vertical frame 23, as shown in Fig. 5. The unlocked position of the handle 7 is a position where the hook portion 92 of the interlocking mechanism 9 is disengaged from the lower engaging wall 263 of the vertical frame-side engaging portion 26 arranged on the vertical frame 23, as shown in Fig. 6.

[0023] As shown in Figures 5, 6, 10 and 11, the handle 7 has a cylindrical handle main body 71 (grip portion) with a rectangular opening that penetrates in the indoor / outdoor direction, and a rear convex portion 72 (rear side metal member) (see Figure 11) that protrudes from the rear of the handle main body 71 toward the vertical frame 53.

[0024] As shown in FIGS. 5 to 7, the handle body 71 is fixed to the vertical frame body 531 with the rear surface 71a extending in the vertical direction arranged along the visible surface 533 of the vertical frame 53.

[0025] The handle body 71 constitutes a handle portion that is used when opening and closing the outer shoji screen 5, and also when locking and unlocking the handle 7. The handle body 71 can be used to open and close the outer shoji screen 5 by manually moving it left and right, and can also be used to lock and unlock the hook portion 92 by manually moving it up and down.

[0026] 11, the rear protrusion 72 is disposed on the rear side of the handle body 71 and is formed integrally with the handle body 71. The rear protrusion 72 protrudes from the rear of the handle body 71 and is formed in the shape of a rectangular parallelepiped block extending in the vertical direction. The rear protrusion 72 has an upper surface 721, a lower surface 722, a rear surface 723, and a pair of side surfaces 724.

[0027] 5 and 6, at least a portion of the rear protrusion 72 is disposed inside the vertical frame 53. The rear protrusion 72 moves up and down by gripping the handle body 71 and moving it up and down.

[0028] As shown in Figure 11, the rear convex portion 72 is formed with an upper through hole 725 that penetrates in the indoor / outdoor direction, a lower through hole 726 that penetrates in the indoor / outdoor direction, and an intermediate open groove 727 that penetrates in the indoor / outdoor direction and opens toward the opposite side of the handle main body 71.

[0029] An upper shaft member 74 is disposed in the upper through-hole 725. A lower shaft member 75 is disposed in the lower through-hole 726. An intermediate shaft member 76 (moving member) is disposed in the intermediate open groove 727 on the side opposite the handle main body 71, and a biasing member 77 is disposed on the handle main body 71 side of the intermediate shaft member 76. The upper shaft member 74, the lower shaft member 75, and the intermediate shaft member 76 are disposed so as to pass through the rear convex portion 72, and move up and down in conjunction with the locking and unlocking operation of the handle 7.

[0030] The biasing member 77 biases the intermediate shaft member 76, which is moved along an intermediate operation resistance change guide groove 834 (described later), in the direction opposite to the handle main body 71.

[0031] As shown in Fig. 10, a handle mechanism 8 is attached to the rear convex portion 72. As shown in Figs. 10 and 11, the handle mechanism 8 includes an operating fitting 731 fixed to the upper side of the rear surface 723 of the rear convex portion 72 of the handle 7, an anti-idle piece 732 provided on the lower side of the rear surface 723 of the rear convex portion 72 of the handle 7, and a mechanism frame 81.

[0032] As shown in Figure 11, the operating fitting 731 is formed in a crank shape. The operating fitting 731 has an upper vertical plate 731a that extends vertically along the back surface 723 of the rear surface convex portion 72 and is fixed to the back surface 723 of the rear surface convex portion 72, an intermediate horizontal plate 731b that extends horizontally from the lower end of the upper vertical plate 731a toward the opposite side from the handle body 71, and a lower vertical plate 731c that extends downward from the end of the intermediate horizontal plate 731b opposite the handle body 71. As shown in Figures 5 and 6, the lower vertical plate 731c is connected to the lower end of an interlocking member 91, which will be described later.

[0033] The empty hanging prevention piece 732 is formed in a convex shape that protrudes from the back surface 723 (the surface on the vertical frame 23 side) of the back surface convex portion 72. The empty hanging prevention piece 732 is attached in a state where it is biased toward the vertical frame 23 side by a biasing member 733 arranged inside the back surface convex portion 72, as shown in Figures 5 and 6 .

[0034] When the outer screen 5 is closed, the anti-idle piece 732 is pushed into the inner periphery of the vertical stile 53 of the outer screen 5 by the anti-idle piece pushing portion 27, and when the outer screen 5 is opened, it is pushed out to the outer periphery of the vertical stile 53 of the outer screen 5 by the biasing member 733. The handle 7 can only be moved downward when the anti-idle piece 732 is pushed in, and cannot be moved downward when the anti-idle piece 732 is protruding outward.

[0035] 7 and 8, the handle mechanism 8 is fixed to the vertical stile body 531 of the vertical stile 53 and the resin material 532 in a state in which it is disposed so as to penetrate through the through openings 532a and 532b of the resin material 532. Two openings 531a and 531b are formed in the vertical stile body 531, side by side in the vertical direction, and the operating fitting 731 and the empty-hanging prevention piece 732 are disposed so as to protrude to the outer periphery side of the vertical stile 53 through the openings 531a and 531b.

[0036] 9 and 10, the mechanism frame 81 has a metal frame 82 (rear metal member) arranged to surround the rear convex portion 72 of the handle 7, a U-shaped resin frame 84 (resin member), and a resin surrounding frame 85 (resin member). The handle 7 is fixed to the vertical frame main body 531 via the mechanism frame 81.

[0037] 10 and 11, the metal frame 82 is disposed on the rear side of the handle body 71 and includes a pair of side frames 83. One of the pair of side frames 83 is disposed on the outdoor side X1, and the other side frame 83 is disposed on the indoor side X2.

[0038] 11, each of the pair of side frames 83 has a side panel 831, an upper panel 835, an upper back panel 836, a lower panel 837, and a lower back panel 838. The side panel 831 is formed in the shape of a plate that extends in the vertical direction and has a thickness in the indoor / outdoor directions.

[0039] The side plate 831 is disposed along the side surface 724 of the rear protrusion 72. The top plate 835 is disposed along the top surface 721 of the rear protrusion 72. The bottom plate 837 is disposed along the bottom surface 722 of the rear protrusion 72. The upper rear plate 836 and the lower rear plate 838 are disposed along the rear surface 723 of the rear protrusion 72.

[0040] The pair of side plates 831 are formed with a pair of upper linear guide grooves 832, a pair of lower linear guide grooves 833, and a pair of middle operation resistance change guide grooves 834 (guide portions).

[0041] As shown in FIG. 11, the pair of upper linear guide grooves 832 are each formed in the upper part of the side plate 831 as a groove penetrating through the thickness direction, and extend linearly in the vertical direction.

[0042] The pair of upper linear guide grooves 832 guide the movement of the upper shaft member 74. Both end portions of the upper shaft member 74 arranged in the upper through-hole 725 of the rear convex portion 72 of the handle 7 are arranged in the pair of upper linear guide grooves 832, respectively. When the handle 7 is moved up and down by the locking / unlocking operation of the handle 7, both end portions of the upper shaft member 74 are guided by the pair of upper linear guide grooves 832 and move up and down along the pair of upper linear guide grooves 832.

[0043] As shown in FIG. 11, the pair of lower linear guide grooves 833 are each formed in the lower part of the side plate 831 as a groove penetrating through the thickness direction, and extending linearly in the vertical direction.

[0044] The pair of lower linear guide grooves 833 guide the movement of the lower shaft member 75. Both end portions of the lower shaft member 75 arranged in the lower through-hole 726 of the rear convex portion 72 of the handle 7 are arranged in the pair of lower linear guide grooves 833, respectively. When the handle 7 is moved up and down by the locking / unlocking operation of the handle 7, both end portions of the lower shaft member 75 are guided by the pair of lower linear guide grooves 833 and move up and down along the pair of lower linear guide grooves 833.

[0045] The pair of intermediate operation resistance change guide grooves 834 guide the movement of the intermediate shaft member 76. As shown in Fig. 11 , the pair of intermediate operation resistance change guide grooves 834 are each formed as a groove penetrating in the thickness direction in an intermediate portion between the upper linear guide groove 832 and the lower linear guide groove 833 in the up-down direction of the side panel 831. Both ends of the intermediate shaft member 76 disposed in the intermediate open groove 727 of the rear convex portion 72 of the handle 7 are disposed in the pair of intermediate operation resistance change guide grooves 834.

[0046] As shown in Figures 12 and 13, when the handle 7 is moved up and down by the locking / unlocking operation of the handle 7, both ends of the intermediate shaft member 76 are guided by a pair of intermediate operation resistance change guide grooves 834 and move up and down along the pair of intermediate operation resistance change guide grooves 834.

[0047] The intermediate operation resistance change guide groove 834 is formed so that the distance from the handle main body 71 varies at the center, top, and bottom in the vertical direction. The intermediate shaft member 76 is urged in the opposite direction to the handle main body 71 by the urging member 77, and therefore, by moving the intermediate shaft member 76 along the intermediate operation resistance change guide groove 834, it is possible to change the operation resistance of the handle 7.

[0048] As shown in Figures 11 to 13, the intermediate operation resistance change guide groove 834 has an upper end locking opening 834a (locking portion), an upper side inclined guide groove 834b (inclined guide portion), a central protruding guide groove 834c (convex guide portion), a lower side inclined guide groove 834d (inclined guide portion), and a lower end locking opening 834e (locking portion).

[0049] The upper end locking opening 834a, the upper side inclined guide groove 834b, the central protruding guide groove 834c, the lower side inclined guide groove 834d and the lower end locking opening 834e are formed continuously in this order from the upper side to the lower side of the intermediate operating resistance change guide groove 834.

[0050] The central protruding guide groove 834c is formed in the center in the up-down direction of the intermediate operation resistance change guide groove 834. The central protruding guide groove 834c is formed in a curved shape that protrudes convexly toward the handle body 71 side.

[0051] The upper-side inclined guide groove 834b is formed on the upper end side (one end side) of the intermediate operation resistance change guide groove 834. The upper-side inclined guide groove 834b is connected to the upper end of the central protruding guide groove 834c. The upper-side inclined guide groove 834b extends at an angle such that the distance from the handle body 71 changes.

[0052] The upper-side inclined guide groove 834b is formed so as to be inclined toward the handle main body 71 as it moves from the upper end side to the lower end side of the intermediate operation resistance change guide groove 834. In other words, the upper-side inclined guide groove 834b is inclined so as to be directed away from the handle main body 71 as it moves upward from the upper end of the central protruding guide groove 834c.

[0053] An upper end locking opening 834a is formed at the upper end of the upper inclined guide groove 834b. The upper end locking opening 834a locks both ends of the intermediate shaft member 76 at the upper end of the intermediate operation resistance change guide groove 834 so as to stop the movement of the handle 7 and hold it in a predetermined position.

[0054] The lower inclined guide groove 834d is formed on the lower end side (other end side) of the intermediate operation resistance change guide groove 834. The lower inclined guide groove 834d is connected to the lower end of the central protruding guide groove 834c. The lower inclined guide groove 834d extends at an angle such that the distance from the handle body 71 changes.

[0055] The lower-side inclined guide groove 834d is formed so as to be inclined toward the handle main body 71 as it moves from the lower end side to the upper end side of the intermediate operation resistance change guide groove 834. In other words, the lower-side inclined guide groove 834d is inclined so as to be directed away from the handle main body 71 as it moves downward from the lower end of the central protruding guide groove 834c.

[0056] A lower end locking opening 834e is formed at the lower end of the lower inclined guide groove 834d. The lower end locking opening 834e locks both ends of the intermediate shaft member 76 at the lower end of the intermediate operation resistance change guide groove 834 so as to stop the movement of the handle 7 and hold it in a predetermined position.

[0057] The handle 7 configured in this manner is attached to the metal frame 82 in a state in which it is movable up and down relative to the metal frame 82. By operating the handle 7 to move it up and down, both ends of the upper shaft member 74, both ends of the lower shaft member 75, and both ends of the intermediate shaft member 76, which are provided on the rear convex portion 72 of the handle 7, are guided along the pair of upper linear guide grooves 832, the pair of lower linear guide grooves 833, and the pair of intermediate operation resistance change guide grooves 834 of the metal frame 82, and the handle 7 moves up and down relative to the metal frame 82.

[0058] When the handle 7 is moved from the upper unlocked position (see Figure 12) to the lower locked position (see Figure 13), both ends of the intermediate shaft member 76 move downward, disengaging from the upper end engagement openings 834a of the pair of intermediate operation resistance change guide grooves 834.

[0059] The intermediate shaft member 76, which has come out of the upper end locking opening 834a and moved downward, moves along the upper side inclined guide groove 834b, then in the middle part, moves along the central protruding guide groove 834c, and on the lower side, moves along the lower side inclined guide groove 834d, and is locked in the lower end locking opening 834e at the lower end of the lower side inclined guide groove 834d.

[0060] As a result, since the intermediate shaft member 76 is biased in the opposite direction to the handle main body 71 by the biasing member 77, when the intermediate shaft member 76 moves from above to below in the upper side inclined guide groove 834b of the intermediate operating resistance change guide groove 834, the operating resistance gradually increases.

[0061] Conversely, when the handle 7 is moved from the lower locked position (see Figure 13) to the upper unlocked position (see Figure 12), both ends of the intermediate shaft member 76 move upward, disengaging from the lower end engagement openings 834e of the pair of intermediate operation resistance change guide grooves 834.

[0062] The intermediate shaft member 76, which has disengaged from the lower end locking opening 834e and moved upward, is moved along the lower side inclined guide groove 834d, then in the middle, moved along the central protruding guide groove 834c, and on the upper side, moved along the upper side inclined guide groove 834b, and is locked in the upper end of the upper side inclined guide groove 834b by the upper end of the upper side inclined guide groove 834b.

[0063] As a result, since the intermediate shaft member 76 is biased in the opposite direction to the handle main body 71 by the biasing member 77, when the intermediate shaft member 76 moves from below to above in the lower side inclined guide groove 834d of the intermediate operating resistance change guide groove 834, the operating resistance gradually increases.

[0064] As described above, with the intermediate shaft member 76 being urged in the opposite direction to the handle main body 71 by the urging member 77, the intermediate shaft member 76 moves while being guided by the intermediate operation resistance change guide groove 834, and as a result, when the handle 7 is moved in the up and down direction to lock or unlock the handle 7, the operation resistance during the locking or unlocking operation of the handle 7 changes. This improves the operability of the handle 7.

[0065] Next, we will explain the configurations of the metal frame 82, the resin U-shaped frame portion 84, and the resin surrounding frame portion 85. The resin U-shaped frame portion 84 and the resin surrounding frame portion 85 are attached to the metal frame 82 so as to surround the metal frame 82, as shown in Figures 9 and 10.

[0066] The resin U-shaped frame portion 84 and the resin surrounding frame portion 85 of the mechanism frame portion 81 are disposed between the handle 7 and the metal frame 82, and are fixed to the vertical frame main body 531. As a result, the handle 7 is fixed to the vertical frame main body 531 via the resin members (the resin U-shaped frame portion 84, the resin surrounding frame portion 85).

[0067] 11 and 12, the resin U-shaped frame portion 84 is formed in a U-shape and arranged along the outer surface of the top plate 835, the outer surface of the upper rear plate 836, the outer surface of the lower rear plate 838, and the outer surface of the bottom plate 837 of the metal frame 82. As shown in FIGS. 9 and 10, the resin U-shaped frame portion 84 has a back resin plate 841 (back plate), an upper resin plate 842 (upper plate), and a lower resin plate 843 (lower plate).

[0068] The rear resin plate 841 is disposed along the outer surface of the upper rear plate 836 and the outer surface of the lower rear plate 838 of the metal frame 82, and is thereby disposed along the rear surface 723 (see FIG. 11) of the rear convex portion 72. The upper resin plate 842 is disposed along the outer surface of the upper plate 835 of the metal frame 82, and is thereby disposed along the upper surface 721 (see FIG. 11) of the rear convex portion 72. The lower resin plate 843 is disposed along the outer surface of the lower plate 837 of the metal frame 82, and is thereby disposed along the lower surface 722 (see FIG. 11) of the rear convex portion 72.

[0069] The rear resin plate 841 is formed to have a thickness in the left-right direction of the fitting 1 and extends in the up-down direction. The rear resin plate 841 is arranged along the upper rear plate 836 and the lower rear plate 838 of the side frame 83 of the metal frame 82.

[0070] An upper opening 841a and a lower slit opening 841b are formed in the rear resin plate 841. An operating fitting 731 fixed to the upper side of the rear surface 723 of the rear protrusion 72 is disposed to pass through the upper opening 841a. An empty hook prevention piece 732 provided on the lower side of the rear surface 723 of the rear protrusion 72 of the handle 7 is disposed to pass through the lower slit opening 841b.

[0071] The upper resin plate 842 extends horizontally from the upper end of the back resin plate 841 toward the handle main body 71. The upper resin plate 842 is arranged along the upper plates 835 of the pair of side frames 83 of the metal frame 82. The lower resin plate 843 extends horizontally from the lower end of the back resin plate 841 toward the handle main body 71. The lower resin plate 843 is arranged along the lower plates 837 of the side frames 83 of the metal frame 82.

[0072] The resin surrounding frame 85 is disposed at the end of the rear convex portion 72 of the handle 7 on the handle main body 71 side. The resin surrounding frame 85 is formed in a frame shape that goes around the outer periphery of the rear convex portion 72 of the handle 7.

[0073] As shown in FIG. 10, the resin surrounding frame portion 85 has a resin frame main body 851 formed in a rectangular frame shape and extending in the vertical direction, an upper protruding resin plate 852, and a lower protruding resin plate 853.

[0074] 9, the resin frame main body 851 is formed so as to wrap around the outer periphery of the rear convex portion 72 of the handle 7 at the end of the metal frame 82 on the handle main body 71 side. The upper protruding resin plate 852 is formed in the shape of a plate that protrudes horizontally on the upper end side of the resin frame main body 851 opposite the handle main body 71. The lower protruding resin plate 853 is formed in the shape of a plate that protrudes horizontally on the lower end side of the resin frame main body 851 opposite the handle main body 71.

[0075] As shown in Figures 5 to 8, the interlocking mechanism part 9 comprises an interlocking member 91 connected to the operating fitting 731 and extending upward from the operating fitting 731, and a hook part 92 connected to the upper end side of the interlocking member 91.

[0076] The interlocking member 91 is formed to extend in the vertical direction and is connected to the handle 7 via the handle mechanism 8. The interlocking member 91 extends upward from the operating fitting 731. When the handle 7 is operated in the vertical direction, the interlocking member 91 moves up and down in conjunction with the up and down movement of the operating fitting 731. By providing the interlocking member 91, when the hook portion 92 is provided at a position away from the handle 7 in the vertical direction, the hook portion 92 can be operated from the operating fitting 731 at a position away from the handle 7 in the vertical direction.

[0077] The hook portion 92 is formed in a hook shape that is open at the bottom. When moved up and down by the interlocking member 91, the hook portion 92 can be moved between a locked position where it is engaged with the lower engaging wall 263 of the vertical frame-side engaging portion 26, and an unlocked position where it is disengaged from the lower engaging wall 263 of the vertical frame-side engaging portion 26. In this embodiment, when the handle 7 is moved downward to the lower position, it is positioned at the locked position, and when the handle 7 is moved upward to the upper position, it is positioned at the locked position.

[0078] This embodiment provides the following advantages: The handle structure 6 for fittings of this embodiment is equipped with a handle 7 that can be moved up and down to lock and unlock. This allows the outer sliding door 5 to be opened and closed and locked and unlocked in one continuous motion using the handle 7, improving operability.

[0079] In this embodiment, the handle 7 is placed in the locked position when moved downward, and in the unlocked position when moved upward. Therefore, by placing the locking position of the handle 7 on the lower side in the direction of gravity, the locking position can be easily maintained even in the event of a malfunction of the handle 7 or an earthquake. This prevents the outer screen 5 from opening unintentionally.

[0080] Furthermore, this embodiment is provided with an interlocking member 91 that is connected to the handle 7 and extends in the vertical direction. Therefore, when the hook portion 92 is provided at a position vertically separated from the handle 7, providing the interlocking member 91 allows the hook portion 92 to be operated at a position vertically separated from the operation fitting 731. This improves the degree of freedom in arranging the vertical frame-side locking portion 26 that locks the hook portion 92 that is operated when the handle 7 is locked or unlocked.

[0081] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0082] In the above embodiment, the door can be locked and unlocked by moving the handle 7 in the up and down direction, but this is not limiting. For example, the door can be locked and unlocked by moving the handle 7 in the left and right direction.

[0083] In the embodiment described above, the biasing member 77 is configured to bias the intermediate shaft member 76 (moving member) in the direction opposite to the handle main body 71, but the present invention is not limited to this. The biasing member 77 may also be configured to bias the intermediate shaft member 76 (moving member) toward the handle main body 71.

[0084] In the above embodiment, the interlocking member 91 is provided between the handle 7 and the hook portion 92, but the present invention is not limited to this. The interlocking member 91 does not have to be provided between the handle 7 and the hook portion 92.

[0085] In the above embodiment, the rear metal member is configured by both the metal frame 82 and the rear convex portion 72 of the handle 7, but this is not limited thereto. The rear metal member may be configured by either the metal frame 82 or the rear convex portion 72 of the handle 7. [Explanation of symbols]
