Embodiments of the present disclosure will be described in detail below with reference to the drawings. One embodiment of a fitting 1 will be described. 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 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 designated as the outdoor side X1, and the indoor side of the fitting 1 is designated as the indoor side X2. The "horizontal direction" of the outer shoji screen 5 is also referred to as the left-right direction.

As shown in Figures 1 and 2, the fixture 1 comprises a frame 2 attached to an opening in the building frame (not shown), a mullion 3 placed within the frame 2, a fixed part 4 placed on the indoor side X2 within the frame 2 on one side of the mullion 3, an outer shoji screen 5 placed on the outdoor side X1 within the frame 2 on the other side of the mullion 3 and movable left and right, and a pleated screen 58 (retractable screen) placed on the indoor side X2 within the frame 2 on the other side of the mullion 3 in the left and right direction and retractable.

The frame body 2 is constructed 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.

As shown in Figure 1, the upright 3 is positioned midway between the left and right sides of the interior side X2 of the frame body 2, extending vertically. The opening of the frame body 2 is divided into left and right halves by the upright 3 midway between the left and right sides. As a result, on the interior side X2 of the frame body 2, a fixed section 4 is formed on one left-right side of the frame body 2, and an opening 25 that is opened and closed by the outer screen 5 is formed on the other left-right side of the frame body 2.

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

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 side X1 of the frame body 2. The outer shoji screen 5 is configured to open and close an opening 25 formed on the other side of the fixed section 4 (the left side in Figures 1 and 2).

The outer shoji screen 5 is constructed by fitting a glass panel 55 onto 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 door tip, and a vertical frame 54 located at the door tail.

As shown in Figure 2, the vertical stile 53 located 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.

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 lateral side of the resin material 532 of the vertical frame 53, on the interior side X2 of the room, relative to the face material 55 of the outer shoji screen 5, using the door handle structure 6.

As shown in Figure 4, the projecting surface 231 of the vertical frame 23 on the door-end side of the frame body 2 is provided with a vertical frame-side locking portion 26 and an anti-empty door-hanging piece push-in portion 27.

The vertical frame-side locking portion 26 is provided on the projecting surface 231 of the vertical frame 23 of the frame body 2. The vertical frame-side locking portion 26 is box-shaped and has an opening 261 that opens toward the inner periphery of the frame body 2 in the left-right direction, a hook accommodating portion 262 that communicates with the opening 261, and a lower locking wall 263 that stands below the opening 261 and protrudes upward in front of the hook accommodating portion 262.

The lower locking wall 263 is formed as a plate that is thick in the left-right direction and extends vertically and in the indoor-outdoor direction. The hook portion 92 (described below) of the interlocking mechanism 9 engages 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 disengages when the handle 7 is unlocked.

The empty-hanging prevention piece pushing-in portion 27 is provided on the projecting 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 projecting surface 231 of the vertical frame 23.

As shown in Figures 5 and 6, the door handle structure 6 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.

The handle 7 can be locked or unlocked by moving it up or 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.

As shown in Figure 5, the locked position of the handle 7 is 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 Figure 6, the unlocked position of the handle 7 is 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 Figures 5, 6, 10, and 11, the handle 7 has a cylindrical handle body 71 (grip portion) with a rectangular opening that penetrates from the inside to the outside, and a rear projection 72 (rear metal member) that protrudes from the rear of the handle body 71 toward the vertical frame 53 (see Figure 11).

As shown in Figures 5 to 7, the handle body 71 is fixed to the vertical stile body 531 with the vertically extending back surface 71a positioned along the visible surface 533 of the vertical stile 53.

The handle body 71 constitutes the handle portion used to open and close the outer shoji screen 5, and also to lock and unlock 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.

As shown in Figure 11, the rear protrusion 72 is located 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.

As shown in Figures 5 and 6, at least a portion of the rear projection 72 is disposed inside the vertical frame 53. The rear projection 72 moves up and down by gripping the handle body 71 and moving it up and down.

As shown in Figure 11, the rear protrusion 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 body 71.

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

The biasing member 77 biases the intermediate shaft member 76, which moves along the intermediate operation resistance change guide groove 834 (described below), in the direction opposite to the handle body 71.

As shown in Figure 10, the handle mechanism 8 is attached to the rear protrusion 72. As shown in Figures 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 protrusion 72 of the handle 7, an anti-idle piece 732 provided on the lower side of the rear surface 723 of the rear protrusion 72 of the handle 7, and a mechanism frame 81.

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 back surface convex portion 72 and is fixed to the back surface 723 of the back surface convex portion 72, an intermediate horizontal plate 731b that extends horizontally from the lower end of the upper vertical plate 731a on the side opposite the handle body 71, and a lower vertical plate 731c that extends downward from the end of the intermediate horizontal plate 731b on the side opposite the handle body 71. As shown in Figures 5 and 6, the lower vertical plate 731c is connected to the lower end of the interlocking member 91, which will be described later.

The anti-empty hanging piece 732 is formed in a convex shape that protrudes from the back surface 723 (the surface facing the vertical frame 23) of the back surface convex portion 72. As shown in Figures 5 and 6, the anti-empty hanging piece 732 is attached while being biased toward the vertical frame 23 by a biasing member 733 arranged inside the back surface convex portion 72.

When the outer screen 5 is closed, the anti-idle piece 732 is pushed into the inner periphery of the vertical frame 53 of the outer screen 5 by the anti-idle piece pushing portion 27, and when the outer screen 5 is opened, the biasing member 733 pushes it outward from the vertical frame 53 of the outer screen 5. The handle 7 can only be moved downward when the anti-idle piece 732 is pushed in; it cannot be moved downward when the anti-idle piece 732 protrudes outward.

As shown in Figures 7 and 8, the handle mechanism 8 is fixed to the vertical stile body 531 and the resin material 532 of the vertical stile 53, with the handle mechanism 8 positioned through the through-openings 532a and 532b of the resin material 532. The vertical stile body 531 has two openings 531a and 531b formed side by side in the vertical direction, and the operating fitting 731 and the empty-hanging prevention piece 732 are positioned so as to protrude outward from the outer periphery of the vertical stile 53 through the openings 531a and 531b.

As shown in Figures 9 and 10, the mechanism frame 81 includes a metal frame 82 (rear metal member) that surrounds the rear protrusion 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 body 531 via the mechanism frame 81.

As shown in Figures 10 and 11, the metal frame 82 is located on the rear side of the handle body 71 and has a pair of side frames 83. One of the pair of side frames 83 is located on the exterior side X1, and the other is located on the interior side X2.

As shown in Figure 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 as a plate that extends vertically and has a thickness in the indoor/outdoor directions.

The side panel 831 is arranged along the side surface 724 of the rear convex portion 72. The top panel 835 is arranged along the top surface 721 of the rear convex portion 72. The bottom panel 837 is arranged along the bottom surface 722 of the rear convex portion 72. The upper back panel 836 and the lower back panel 838 are arranged along the back surface 723 of the rear convex portion 72.

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 intermediate operating resistance change guide grooves 834 (guide portions).

As shown in Figure 11, the pair of upper linear guide grooves 832 are each formed as a groove penetrating the thickness direction at the top of the side panel 831 and extending linearly in the vertical direction.

The pair of upper linear guide grooves 832 guide the movement of the upper shaft member 74. Both ends of the upper shaft member 74, which are positioned in the upper through-hole 725 of the rear convex portion 72 of the handle 7, are positioned in the pair of upper linear guide grooves 832, respectively. When the handle 7 is moved up and down due to the locking/unlocking operation of the handle 7, both ends 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.

As shown in Figure 11, the pair of lower linear guide grooves 833 are each formed as grooves that penetrate the thickness direction at the bottom of the side panel 831 and extend linearly in the vertical direction.

The pair of lower linear guide grooves 833 guide the movement of the lower shaft member 75. Both ends of the lower shaft member 75, which are positioned in the lower through-hole 726 of the rear convex portion 72 of the handle 7, are positioned in the pair of lower linear guide grooves 833, respectively. When the handle 7 is moved up and down due to the locking/unlocking operation of the handle 7, both ends 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.

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 grooves that penetrate the thickness direction in the 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, which is positioned in the intermediate open groove 727 of the rear convex portion 72 of the handle 7, are positioned in the pair of intermediate operation resistance change guide grooves 834.

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 the 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.

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 biased in the opposite direction to the handle main body 71 by the biasing member 77, so that the intermediate shaft member 76 can move along the intermediate operation resistance change guide groove 834 to change the operation resistance of the handle 7.

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).

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

The central protruding guide groove 834c is formed in the vertical center 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.

The upper 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 inclined guide groove 834b is connected to the upper end of the central protruding guide groove 834c. The upper inclined guide groove 834b extends at an angle so that the distance from the handle body 71 changes.

The upper inclined guide groove 834b is formed so as to incline toward the handle body 71 as it moves from the upper end to the lower end of the intermediate operation resistance change guide groove 834. In other words, the upper inclined guide groove 834b inclines toward the opposite side from the handle body 71 as it moves upward from the upper end of the central protruding guide groove 834c.

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 operating resistance change guide groove 834, stopping the movement of the handle 7 and holding it in a predetermined position.

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 so that the distance from the handle body 71 changes.

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

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 operating resistance change guide groove 834, stopping the movement of the handle 7 and holding it in a predetermined position.

The handle 7 configured in this manner is attached to the metal frame 82 so as to be 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 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, causing the handle 7 to move up and down relative to the metal frame 82.

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 disengage from the upper end locking openings 834a of the pair of intermediate operation resistance change guide grooves 834 and move downward.

After disengaging from the upper end locking opening 834a and moving downward, the intermediate shaft member 76 moves along the upper inclined guide groove 834b, then along the central protruding guide groove 834c in the middle, and then along the lower inclined guide groove 834d on the lower side, until the lower end of the lower inclined guide groove 834d is locked in the lower end locking opening 834e.

As a result, the intermediate shaft member 76 is biased in the opposite direction from the handle body 71 by the biasing member 77, and as the intermediate shaft member 76 moves from top to bottom along the upper inclined guide groove 834b of the intermediate operation resistance change guide groove 834, the operation resistance gradually increases.

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 locking openings 834e of the pair of intermediate operation resistance change guide grooves 834.

After disengaging from the lower end locking opening 834e and moving upward, the intermediate shaft member 76 moves along the lower inclined guide groove 834d, then along the central protruding guide groove 834c in the middle, and along the upper inclined guide groove 834b on the upper side, until the upper end of the upper inclined guide groove 834b is locked in the upper end locking opening 834a.

As a result, the intermediate shaft member 76 is biased in the opposite direction from the handle body 71 by the biasing member 77, and as the intermediate shaft member 76 moves from bottom to top along the lower inclined guide groove 834d of the intermediate operation resistance change guide groove 834, the operation resistance gradually increases.

As described above, when the intermediate shaft member 76 is biased in the opposite direction from the handle body 71 by the biasing member 77, the intermediate shaft member 76 moves while being guided by the intermediate operation resistance change guide groove 834. As a result, when the handle 7 is moved in the vertical 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.

Next, the configuration of the metal frame 82, the resin U-shaped frame portion 84, and the resin surrounding frame portion 85 will be described. As shown in Figures 9 and 10, 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.

The resin U-shaped frame portion 84 and resin surrounding frame portion 85 of the mechanism frame portion 81 are positioned 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 (resin U-shaped frame portion 84, resin surrounding frame portion 85).

As shown in Figures 11 and 12, the resin U-shaped frame portion 84 is formed in a U-shape and is arranged along the outer surfaces of the upper plate 835, upper back plate 836, lower back plate 838, and lower plate 837 of the metal frame 82. As shown in Figures 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).

The rear resin plate 841 is positioned 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 positioned along the rear surface 723 of the rear convex portion 72 (see Figure 11). The upper resin plate 842 is positioned along the outer surface of the upper plate 835 of the metal frame 82, and is thereby positioned along the upper surface 721 of the rear convex portion 72 (see Figure 11). The lower resin plate 843 is positioned along the outer surface of the lower plate 837 of the metal frame 82, and is thereby positioned along the lower surface 722 of the rear convex portion 72 (see Figure 11).

The rear resin plate 841 is formed with 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 lower rear plate 838 of the side frame 83 of the metal frame 82.

The rear resin plate 841 is formed with an upper opening 841a and a lower slit opening 841b. The upper opening 841a is fitted with an operating fitting 731 fixed to the upper side of the rear surface 723 of the rear protrusion 72. The lower slit opening 841b is fitted with an anti-idle piece 732 attached to the lower side of the rear surface 723 of the rear protrusion 72 of the handle 7.

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

The resin surrounding frame 85 is located at the end of the rear convex portion 72 of the handle 7 on the handle body 71 side. The resin surrounding frame 85 is formed in a frame shape that surrounds the outer periphery of the rear convex portion 72 of the handle 7.

As shown in Figure 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.

As shown in Figure 9, the resin frame main body 851 is formed around the outer periphery of the rear convex portion 72 of the handle 7 at the end of the metal frame 82 facing the handle main body 71. The upper protruding resin plate 852 is formed as a plate that protrudes horizontally from the upper end of the resin frame main body 851 on the side opposite the handle main body 71. The lower protruding resin plate 853 is formed as a plate that protrudes horizontally from the lower end of the resin frame main body 851 on the side opposite the handle main body 71.

As shown in Figures 5 to 8, the interlocking mechanism 9 includes an interlocking member 91 that is connected to the operating fitting 731 and extends upward from the operating fitting 731, and a hook portion 92 that is connected to the upper end of the interlocking member 91.

The interlocking member 91 extends vertically 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 vertically, the interlocking member 91 moves vertically in conjunction with the vertical movement of the operating fitting 731. By providing the interlocking member 91, when the hook portion 92 is provided at a position vertically separated from the handle 7, the hook portion 92 can be operated from the operating fitting 731 at a position vertically separated.

The hook portion 92 is formed in a hook shape with an open bottom. When moved vertically 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 in the locked position, and when the handle 7 is moved upward to the upper position, it is positioned in the locked position.

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

In addition, 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 setting the locking position of the handle 7 on the lower side in the direction of gravity, the locked position can be easily maintained even if there is a malfunction with the handle 7 or if an earthquake occurs. This prevents the outer shoji screen 5 from opening unintentionally when not intended.

In addition, this embodiment is equipped 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 from the operating fitting 731 at a position vertically separated.
