Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The fitting 1 of one embodiment will be described. In this specification, the "viewing direction" means the surface direction of the facing material in the fitting 1 housed in the opening formed in the wall of the building, and the "depth direction" means the thickness direction (that is, the depth direction) of the facing material. The "depth direction" is also the indoor-outdoor direction. The "viewing surface" means each surface facing the outdoor side and the indoor side of the fitting 1, and the "depth surface" means the surface extending in the indoor-outdoor direction in the fitting 1. 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. Also, the "lateral direction" of the outer shutter 5 is also referred to as the left-right direction.

[0009] As shown in FIGS. 1 and 2, the building fixture 1 includes a frame body 2 attached to an opening of a building body (not shown), a vertical member 3 disposed within the frame body 2, a FIX portion 4 disposed on the indoor side X2 within the frame body 2 on one side in the left-right direction of the vertical member 3, an outer shutter 5 disposed on the outdoor side X1 within the frame body 2 on the other side in the left-right direction of the vertical member 3 and movable in the left-right direction, and a pleated screen door 58 (retractable screen door) disposed on the indoor side X2 in a pull-out manner on the other side in the left-right direction of the vertical member 3 within the frame body 2.

[0010] The frame body 2 is configured 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.

[0011] As shown in FIG. 1, the vertical member 3 is disposed to extend in the vertical direction at an intermediate portion 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 in the middle by the vertical member 3. As a result, on one side in the left-right direction of the frame body 2 on the indoor side X2, the FIX portion 4 is formed, and on the other side in the left-right direction of the frame body 2, an opening 25 that is opened and closed by the outer shutter 5 is formed.

[0012] As shown in FIGS. 1 and 2, the FIX portion 4 is configured by fixing a glass panel 41 as a facing material to the vertical member 3 and the frame body 2 on one side in the left-right direction of the vertical member 3 within the frame body 2 (the right side in FIGS. 1 and 2). The FIX portion 4 is a fixed window that cannot be opened or closed.

[0013] The outer shutter 5 is a shutter that can slide and move in the left-right direction (horizontal direction) within the frame body 2 on the outdoor side X1 within the frame body 2. The outer shutter 5 is configured to be able to open and close an opening 25 formed on the other side (the left side in FIGS. 1 and 2) of the FIX portion 4.

[0014] The outer shutter 5 is configured by housing a facing material 55 made of glass on the inner peripheral side of a frame body 50 formed by framing an upper frame (not shown), a lower frame 52, a vertical frame 53 disposed on the leading end side of the door, and a vertical frame 54 disposed on the trailing end side of the door in a rectangular shape.

[0015] The vertical frame 53 disposed on the door end side has a vertical frame main body 531 and a resin material 532 as shown in Fig. 2. The end of the facing material 55 on the vertical frame 53 side is sandwiched and held between the vertical frame main body 531 and the resin material 532.

[0016] As shown in Figs. 1 to 6, a handle 7 is attached to the prospective surface 533 of the vertical frame 53 disposed on the door end side. The handle 7 is attached to the prospective surface 533 on the inner peripheral side in the left - right direction of the resin material 532 of the vertical frame 53 on the indoor side X2 with respect to the facing material 55 of the outer shutter 5 by a handle structure 6 for fittings.

[0017] As shown in Fig. 4, a vertical frame side locking portion 26 and a hanging - prevention piece pushing portion 27 are provided on the prospective surface 231 of the vertical frame 23 on the door end side of the frame body 2.

[0018] The vertical frame side locking portion 26 is provided on the prospective 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 peripheral side in the left - right direction of the frame body 2, a hook housing portion 262 communicating with the opening 261, and a lower locking wall 263 that stands upright so as to protrude upward below the opening 261 and in front of the hook housing portion 262.

[0019] The lower locking wall 263 has a thickness in the left - right direction and is formed in a plate shape extending in the vertical direction and the indoor - outdoor direction. At the upper end portion of the lower locking wall 263, a hook portion 92 (described later) of the interlocking mechanism portion 9 is locked during the locking operation of the handle 7, and the locking of the hook portion 92 of the interlocking mechanism portion 9 is released during the unlocking operation of the handle 7.

[0020] The hanging - prevention piece pushing portion 27 is provided on the prospective surface 231 of the vertical frame 23 of the frame body 2 below the vertical frame side locking portion 26. The hanging - prevention piece pushing portion 27 is formed in a box shape protruding from the prospective surface 231 of the vertical frame 23.

[0021] As shown in FIGS. 5 and 6, the handle structure 6 for fittings includes a handle 7, a handle mechanism portion 8 connected to the handle 7, and an interlocking mechanism portion 9 connected to the handle mechanism portion 8. The handle 7 is attached to a vertical frame 53 disposed on the door tip side via the handle mechanism portion 8. The interlocking mechanism portion 9 is connected to the handle 7 by being connected to the handle mechanism portion 8.

[0022] The handle 7 can be locked and unlocked by moving it up and down (in the finding direction). When the handle 7 is moved downward, it is disposed at the locked position (see FIG. 5), and when it is moved upward, it is disposed at the unlocked position (see FIG. 6). The handle 7 is made of metal.

[0023] As shown in FIG. 5, the locked position of the handle 7 is a position where the hook portion 92 of the interlocking mechanism portion 9 is locked to the lower locking wall 263 of the vertical frame side locking portion 26 disposed on the vertical frame 23. As shown in FIG. 6, the unlocked position of the handle 7 is a position where the hook portion 92 of the interlocking mechanism portion 9 is disengaged from the lower locking wall 263 of the vertical frame side locking portion 26 disposed on the vertical frame 23.

[0024] As shown in FIGS. 5, 6, 10, and 11, the handle 7 has a cylindrical handle body 71 (grip portion) having a rectangular opening penetrating in the indoor-outdoor direction, and a rear convex portion 72 (rear side metal member) protruding from the back surface of the handle body 71 toward the vertical frame 53 side (see FIG. 11).

[0025] As shown in FIGS. 5 to 7, the handle body 71 is fixed to the vertical frame main body 531 in a state where the rear surface 71a extending in the vertical direction is disposed along the expected surface 533 of the vertical frame 53.

[0026] The handle body 71 constitutes a grip portion that is used during the opening and closing operation of the exterior member 5 and during the locking and unlocking operation of the handle 7. The handle body 71 can perform the opening and closing operation of the exterior member 5 by moving the exterior member 5 left and right with the hand, and can perform the locking and unlocking operation of the hook portion 92 by moving it up and down with the hand.

[0027] As shown in FIG. 11, the rear convex portion 72 is disposed on the rear side of the handle body 71 and is integrally formed with the handle body 71. The rear convex portion 72 protrudes from the rear surface of the handle body 71 and is formed in a rectangular parallelepiped block shape extending in the vertical direction. The rear convex portion 72 has an upper surface 721, a lower surface 722, a rear surface 723, and a pair of side surfaces 724.

[0028] As shown in FIGS. 5 and 6, at least a part of the rear convex portion 72 is disposed inside the vertical frame 53. The rear convex portion 72 moves in the vertical direction by gripping the handle body 71 and moving it in the vertical direction.

[0029] As shown in FIG. 11, the rear convex portion 72 is formed with an upper through hole 725 penetrating in the indoor-outdoor direction, a lower through hole 726 penetrating in the indoor-outdoor direction, and an intermediate open groove 727 penetrating in the indoor-outdoor direction and opening toward the side opposite to the handle body 71.

[0030] 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 to the handle body 71, and a biasing member 77 is disposed on the handle 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 through the rear convex portion 72 and move in the vertical direction in conjunction with the locking and unlocking operation of the handle 7.

[0031] The biasing member 77 biases the intermediate shaft member 76 that moves along the intermediate operation resistance change guide groove 834 (described later) to the side opposite to the handle body 71.

[0032] As shown in FIG. 10, a handle mechanism portion 8 is attached to the rear convex portion 72. As shown in FIGS. 10 and 11, the handle mechanism portion 8 includes an operation fitting 731 fixed to the upper side of the rear surface 723 of the rear convex portion 72 of the handle 7, a hanging prevention 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 portion 81.

[0033] As shown in FIG. 11, the operating fitting 731 is formed in a crank shape. The operating fitting 731 includes an upper vertical plate 731a that extends in the vertical direction along the rear surface 723 of the rear convex portion 72 and is fixed to the rear surface 723 of the rear convex portion 72, an intermediate horizontal plate 731b that extends horizontally from the lower end of the upper vertical plate 731a to the side opposite to 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 to the handle body 71. The lower vertical plate 731c is connected to the lower end portion of an interlocking member 91, which will be described later, as shown in FIGS. 5 and 6.

[0034] The anti-idling piece 732 is formed in a convex shape that protrudes from the rear surface 723 (the surface on the side of the vertical frame 23) of the rear convex portion 72. As shown in FIGS. 5 and 6, the anti-idling piece 732 is attached in a state of being biased toward the vertical frame 23 side by a biasing member 733 disposed inside the rear convex portion 72.

[0035] When the outer sash 5 is closed, the anti-idling piece 732 is pushed into the inner peripheral side of the vertical frame 53 of the outer sash 5 by the anti-idling piece pushing portion 27, and when the outer sash 5 is opened, the anti-idling piece 732 is pushed out to the outer peripheral side of the vertical frame 53 of the outer sash 5 by the biasing member 733. The handle 7 can be moved downward only when the anti-idling piece 732 is in a pushed-in state, and cannot be moved downward when the anti-idling piece 732 protrudes to the outer peripheral side.

[0036] As shown in FIGS. 7 and 8, the handle mechanism portion 8 is disposed so as to penetrate through the through openings 532a and 532b of the resin material 532 and is fixed to the vertical frame body 531 and the resin material 532 of the vertical frame 53. Two openings 531a and 531b are formed in the vertical frame body 531 side by side in the vertical direction, and the operating fitting 731 and the anti-idling piece 732 are disposed so as to protrude to the outer peripheral side of the vertical frame 53 through the openings 531a and 531b.

[0037] As shown in FIGS. 9 and 10, the mechanism frame portion 81 includes a metal frame 82 (rear side metal member) arranged to surround the rear convex portion 72 of the handle 7, a U-shaped resin U-shaped frame portion 84 (resin member), and a resin circumferential frame portion 85 (resin member). The handle 7 is fixed to the vertical frame body 531 via the mechanism frame portion 81.

[0038] As shown in FIGS. 10 and 11, the metal frame 82 is arranged 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 arranged on the outdoor side X1, and the other side frame 83 is arranged on the indoor side X2.

[0039] As shown in FIG. 11, each of the pair of side frames 83 has a side plate 831, an upper plate 835, an upper rear plate 836, a lower plate 837, and a lower rear plate 838. The side plate 831 is formed in a plate shape that extends in the vertical direction and has a thickness in the indoor-outdoor direction.

[0040] The side plate 831 is arranged along the side surface 724 of the rear convex portion 72. The upper plate 835 is arranged along the upper surface 721 of the rear convex portion 72. The lower plate 837 is arranged along the lower surface 722 of the rear convex portion 72. The upper rear plate 836 and the lower rear plate 838 are arranged along the rear surface 723 of the rear convex portion 72.

[0041] A pair of upper linear guide grooves 832, a pair of lower linear guide grooves 833, and a pair of intermediate operation resistance change guide grooves 834 (guide portions) are formed in the pair of side plates 831.

[0042] As shown in FIG. 11, each of the pair of upper linear guide grooves 832 is formed in a groove shape that penetrates in the thickness direction at the upper part of the side plate 831 and extends linearly in the vertical direction.

[0043] A pair of upper linear guide grooves 832 guide the movement of the upper shaft member 74. Both ends of the upper shaft member 74 are respectively disposed in the upper through holes 725 of the rear convex portion 72 of the handle 7 and are arranged in the pair of upper linear guide grooves 832. Both ends of the upper shaft member 74 are guided by the pair of upper linear guide grooves 832 and move vertically along the pair of upper linear guide grooves 832 when the handle 7 is moved vertically by the locking and unlocking operation of the handle 7.

[0044] As shown in FIG. 11, a pair of lower linear guide grooves 833 are respectively formed in a groove shape penetrating in the thickness direction at the lower part of the side plate 831 and extending linearly in the vertical direction.

[0045] A pair of lower linear guide grooves 833 guide the movement of the lower shaft member 75. Both ends of the lower shaft member 75 are respectively disposed in the lower through holes 726 of the rear convex portion 72 of the handle 7 and are arranged in the pair of lower linear guide grooves 833. Both ends of the lower shaft member 75 are guided by the pair of lower linear guide grooves 833 and move vertically along the pair of lower linear guide grooves 833 when the handle 7 is moved vertically by the locking and unlocking operation of the handle 7.

[0046] A pair of intermediate operation resistance change guide grooves 834 guide the movement of the intermediate shaft member 76. As shown in FIG. 11, a pair of intermediate operation resistance change guide grooves 834 are respectively formed in a groove shape penetrating in the thickness direction at an intermediate portion between the upper linear guide groove 832 and the lower linear guide groove 833 in the vertical direction of the side plate 831. Both ends of the intermediate shaft member 76 are disposed in the intermediate open grooves 727 of the rear convex portion 72 of the handle 7 and are arranged in the pair of intermediate operation resistance change guide grooves 834.

[0047] As shown in FIGS. 12 and 13, both ends of the intermediate shaft member 76 are guided by the pair of intermediate operation resistance change guide grooves 834 and move vertically along the pair of intermediate operation resistance change guide grooves 834 when the handle 7 is moved vertically by the locking and unlocking operation of the handle 7.

[0048] The intermediate operation resistance change guide groove 834 is formed such that the distances from the handle body 71 are different at the center in the vertical direction, at the upper part, and at the lower part. Since the intermediate shaft member 76 is biased to the side opposite to the handle body 71 by the biasing member 77, it is possible to change the operation resistance of the handle 7 by moving the intermediate shaft member 76 along the intermediate operation resistance change guide groove 834.

[0049] As shown in FIGS. 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).

[0050] 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 continuously formed in this order from the upper side to the lower side of the intermediate operation resistance change guide groove 834.

[0051] The central protruding guide groove 834c is formed at the center in the vertical direction of the intermediate operation resistance change guide groove 834. The central protruding guide groove 834c is formed in a rounded shape that protrudes convexly toward the handle body 71 side.

[0052] The upper side inclined guide groove 834b is formed at 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 obliquely so that the distance from the handle body 71 changes.

[0053] The upper side inclined guide groove 834b is formed to be inclined so as to face the handle body 71 side as it goes 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 face the side opposite to the handle body 71 as it goes upward from the upper end of the central protruding guide groove 834c.

[0054] At the upper end of the upper side inclined guide groove 834b, an upper end locking opening 834a is formed. The upper end locking opening 834a locks both ends of the intermediate shaft member 76 at the upper end of the intermediate operation resistance changing guide groove 834 so as to stop the movement of the handle 7 and hold it at a predetermined position.

[0055] The lower side inclined guide groove 834d is formed on the lower end side (the other end side) of the intermediate operation resistance changing guide groove 834. The lower side inclined guide groove 834d is connected to the lower end of the central protruding guide groove 834c. The lower side inclined guide groove 834d extends obliquely so that the distance from the handle body 71 changes.

[0056] The lower side inclined guide groove 834d is formed to be inclined so as to face the handle body 71 side as it goes from the lower end side to the upper end side of the intermediate operation resistance changing guide groove 834. In other words, the lower side inclined guide groove 834d is inclined so as to face the side opposite to the handle body 71 as it goes downward from the lower end of the central protruding guide groove 834c.

[0057] At the lower end of the lower side inclined guide groove 834d, a lower end locking opening 834e is formed. The lower end locking opening 834e locks both ends of the intermediate shaft member 76 at the lower end of the intermediate operation resistance changing guide groove 834 so as to stop the movement of the handle 7 and hold it at a predetermined position.

[0058] The handle 7 configured in this way is attached to the metal frame 82 in a state where it can move relatively in the vertical direction with respect to the metal frame 82. By operating the handle 7 to move it in the vertical direction, 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 a pair of upper linear guide grooves 832, a pair of lower linear guide grooves 833, and a pair of intermediate operation resistance changing guide grooves 834 of the metal frame 82, so that the handle 7 moves in the vertical direction with respect to the metal frame 82.

[0059] When the handle 7 moves from the upper unlocking position (see Fig. 12) to the lower locking position (see Fig. 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.

[0060] The intermediate shaft member 76 that has disengaged from the upper end locking opening 834a and moved downward is moved along the upper side inclined guide groove 834b, moved along the central protruding guide groove 834c in the middle part, and moved along the lower side inclined guide groove 834d on the lower side, and is locked to the lower end locking opening 834e at the lower end of the lower side inclined guide groove 834d.

[0061] Thus, since the intermediate shaft member 76 is biased by the biasing member 77 to the side opposite to the handle body 71, when the intermediate shaft member 76 moves downward from above along the upper side inclined guide groove 834b of the intermediate operation resistance change guide groove 834, the operation resistance gradually increases.

[0062] Conversely, when the handle 7 moves from the lower locking position (see Fig. 13) to the upper unlocking position (see Fig. 12), both ends of the intermediate shaft member 76 disengage from the lower end locking openings 834e of the pair of intermediate operation resistance change guide grooves 834 and move upward.

[0063] The intermediate shaft member 76 that has disengaged from the lower end locking opening 834e and moved upward is moved along the lower side inclined guide groove 834d, moved along the central protruding guide groove 834c in the middle part, and moved along the upper side inclined guide groove 834b on the upper side, and is locked to the upper end locking opening 834a at the upper end of the upper side inclined guide groove 834b.

[0064] Thus, since the intermediate shaft member 76 is biased by the biasing member 77 to the side opposite to the handle body 71, when the intermediate shaft member 76 moves upward from below along the lower side inclined guide groove 834d of the intermediate operation resistance change guide groove 834, the operation resistance gradually increases.

[0065] As described above, with the intermediate shaft member 76 biased by the biasing member 77 to the side opposite to the handle body 71, when the intermediate shaft member 76 is guided by the intermediate operation resistance change guide groove 834 and moves, when the handle 7 is moved in the vertical direction during locking and unlocking of the handle 7, the operation resistance during the locking and unlocking operation of the handle 7 changes. Thereby, the operation feeling of the handle 7 can be improved.

[0066] Next, the configurations 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 FIGS. 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.

[0067] 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 fixed to the vertical frame main body 531. As a result, the handle 7 is fixed to the vertical frame main body 531 via resin members (resin U-shaped frame portion 84, resin surrounding frame portion 85).

[0068] As shown in FIGS. 11 and 12, the resin U-shaped frame portion 84 is formed in a U shape disposed along the outer surfaces of the upper surface plate 835, the upper back plate 836, the lower back plate 838, and the lower surface 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 surface plate), and a lower resin plate 843 (lower surface plate).

[0069] The back resin plate 841 is disposed along the outer surfaces of the upper back plate 836 and the lower back plate 838 of the metal frame 82, and thus is disposed along the back surface 723 of the back convex portion 72 (see FIG. 11). The upper resin plate 842 is disposed along the outer surface of the upper surface plate 835 of the metal frame 82, and thus is disposed along the upper surface 721 of the back convex portion 72 (see FIG. 11). The lower resin plate 843 is disposed along the outer surface of the lower surface plate 837 of the metal frame 82, and thus is disposed along the lower surface 722 of the back convex portion 72 (see FIG. 11).

[0070] 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 the lower rear plate 838 of the side frame 83 of the metal frame 82.

[0071] 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 convex portion 72 penetrates and is arranged in the upper opening 841a. A hanging prevention piece 732 provided on the lower side of the rear surface 723 of the rear convex portion 72 of the handle 7 penetrates and is arranged in the lower slit opening 841b.

[0072] The upper resin plate 842 extends horizontally from the upper end of the rear resin plate 841 toward the handle body 71 side. The upper resin plate 842 is arranged along the upper surface plate 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 rear resin plate 841 toward the handle body 71 side. The lower resin plate 843 is arranged along the lower surface plate 837 of the side frame 83 of the metal frame 82.

[0073] The resin surrounding frame portion 85 is arranged at the end portion on the handle body 71 side of the rear convex portion 72 of the handle 7. The resin surrounding frame portion 85 is formed in a frame shape that surrounds along the outer peripheral edge of the rear convex portion 72 of the handle 7.

[0074] As shown in FIG. 10, the resin surrounding frame portion 85 has a resin frame body 851 formed in a rectangular frame shape and extending in the up-down direction, an upper protruding resin plate 852, and a lower protruding resin plate 853.

[0075] As shown in FIG. 9, the resin frame body 851 is formed to surround along the outer peripheral edge of the rear convex portion 72 of the handle 7 at the end portion on the handle body 71 side of the metal frame 82. The upper protruding resin plate 852 is formed in a plate shape that protrudes horizontally on the opposite side of the handle body 71 at the upper end portion side of the resin frame body 851. The lower protruding resin plate 853 is formed in a plate shape that protrudes horizontally on the opposite side of the handle body 71 at the lower end portion side of the resin frame body 851.

[0076] As shown in FIGS. 5 to 8, the interlocking mechanism portion 9 includes an interlocking member 91 connected to the operating fitting 731 and extending upward from the operating fitting 731, and a hook portion 92 connected to the upper end portion side of the interlocking member 91.

[0077] The interlocking member 91 is formed to extend in the vertical direction and is connected to the handle 7 via the handle mechanism portion 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 vertical movement of the operating fitting 731. By providing the interlocking member 91, when the hook portion 92 is provided at a position separated from the handle 7 in the vertical direction, the hook portion 92 can be operated at a position separated from the operation from the operating fitting 731 in the vertical direction.

[0078] The hook portion 92 is formed in a hook shape with an open bottom. When the hook portion 92 is moved in the vertical direction by the interlocking member 91, it can move to a locked position where it is locked to the lower locking wall 263 of the vertical frame side locking portion 26 and an unlocked position where it is disengaged from the lower locking wall 263 of the vertical frame side locking portion 26. In the present embodiment, when the handle 7 is moved downward and located at the lower position, it is located at the locked position, and when the handle 7 is moved upward and located at the upper position, it is located at the locked position.

[0079] According to the present embodiment, the following effects are achieved. The handle structure 6 for a building fixture of the present embodiment includes an outer shutter 5 having a vertical frame 53 and a metal handle 7 fixed to the vertical frame 53 via resin members (resin U-shaped frame portion 84, resin surrounding frame portion 85). Thereby, since the resin members (resin U-shaped frame portion 84, resin surrounding frame portion 85) are arranged between the vertical frame 53 of the outer shutter 5 and the metal handle 7, the heat insulation performance and the dew prevention performance can be improved.

[0080] Further, in the present embodiment, the handle 7 includes a handle main body 71, a rear convex portion 72 and a metal frame 82 disposed on the rear side of the handle main body 71, and the resin members (resin U-shaped frame portion 84, resin circumferential frame portion 85) are disposed between the rear convex portion 72 and the metal frame 82 and the vertical frame 53. Thereby, with a simple configuration in which only the resin members (resin U-shaped frame portion 84, resin circumferential frame portion 85) are disposed between the rear convex portion 72 and the metal frame 82 of the handle 7 and the vertical frame 53, the heat insulation performance and the dew prevention performance can be improved.

[0081] Further, in the present embodiment, the metal frame 82 has an upper panel 835, a lower panel 837, an upper rear panel 836 and a lower rear panel 838, and the resin member includes an upper resin plate 842 disposed along the upper panel 835, a lower resin plate 843 disposed along the lower panel 837, and a rear resin plate 841 disposed along the upper rear panel 836 and the lower rear panel 838, and is provided with a U-shaped resin U-shaped frame portion 84. Thereby, on the upper rear panel 836 side and the lower rear panel 838 side of the metal frame 82, by disposing the resin U-shaped frame portion 84 between the vertical frame 53 side of the handle 7 and the vertical frame 53, the heat insulation performance and the dew prevention performance on the vertical frame 53 side of the handle 7 can be improved.

[0082] Further, in the present embodiment, the resin member has a frame-shaped resin circumferential frame portion 85 that is disposed at an end portion of the rear convex portion 72 on the handle main body 71 side and that circulates along the outer peripheral edge of the rear convex portion 72. Thereby, on the handle main body 71 side of the rear convex portion 72, by disposing the resin circumferential frame portion 85 between the outer peripheral edge of the rear convex portion 72 of the handle 7 and the vertical frame 53, the heat insulation performance and the dew prevention performance on the outer peripheral edge side of the handle main body 71 side of the rear convex portion 72 of the handle 7 can be improved.

[0083] As described above, a preferred embodiment of the present disclosure has been described. However, the present disclosure is not limited to the above-described embodiment and can be appropriately modified.

[0084] In the above embodiment, the configuration is such that the lock can be locked and unlocked by moving the handle 7 in the vertical direction, but it is not limited thereto. For example, the configuration may be such that the lock can be locked and unlocked by moving the handle 7 in the horizontal direction.

[0085] In the above-described embodiment, the biasing member 77 is configured to bias the intermediate shaft member 76 (moving member) to the side opposite to the handle body 71, but the present invention is not limited thereto. The biasing member 77 may be configured to bias the intermediate shaft member 76 (moving member) toward the handle body 71 side.

[0086] In the above-described embodiment, the interlocking member 91 is provided between the handle 7 and the hook portion 92, but the present invention is not limited thereto. The interlocking member 91 may not be provided between the handle 7 and the hook portion 92.

[0087] In the above-described embodiment, the rear side metal member is constituted by both the metal frame 82 and the rear convex portion 72 of the handle 7, but the present invention is not limited thereto. The rear side metal member may be constituted by either one of the metal frame 82 and the rear convex portion 72 of the handle 7.
