Description

[Technical Field]

[0001] The present invention relates to a fitting having a shoji screen attached to a frame so as to be able to open and close. [Background technology]

[0002] In fixtures with openable shoji screens, the opening of the screen may be restricted for safety reasons. For example, in a sliding window, the screen may be allowed to open to a limited position on the outdoor side, but may be restricted from being fully opened to the outdoor side. A known device for restricting the opening of such shoji screens is an opening limiting stopper device for casement windows, which uses an arm to keep the shoji screen in a half-open position (see Patent Document 1).

[0003] In the conventional opening limiting stopper device described in Patent Document 1, when the shoji screen is opened, an arm pivotally attached to the frame supports the screen in a half-open position. A switch knob switches between fully open and half-open positions, and moving the switch knob allows the screen to be fully opened. However, with conventional opening limiting stopper devices, there is a risk that the switch knob may be moved by mistake. In this case, the restriction on the opening of the shoji screen may be accidentally released, allowing the screen screen to be unintentionally fully opened. [Prior art documents] [Patent documents]

[0009] An embodiment of the fitting of the present invention will be described with reference to the drawings. The fittings of this embodiment are fittings equipped with opening and closing shoji screens, and are installed in openings of buildings. The fittings are also installed between the interior (indoor) and exterior (outdoor) of a building to close the openings of the building. Below, the fittings of this embodiment will be explained using as an example a sliding window, which is an outward-opening fitting.

[0010] Fig. 1 is a front view showing the fitting 1 of this embodiment, showing the fitting 1 installed in a building as viewed from the indoor side. Fig. 2 is a longitudinal cross-sectional view showing the fitting 1 of this embodiment, showing the fitting 1 cut along a plane including the up-down direction R and the indoor-outdoor direction T. Fig. 3 is a transverse cross-sectional view showing the fitting 1 of this embodiment, showing the fitting 1 cut along a plane including the left-right direction S and the indoor-outdoor direction T. Figs. 2 and 3 schematically show the shape of the fitting 1. As shown in the figure, the fitting 1 comprises a shoji screen 2 that opens and closes by pivoting, a frame 3 that surrounds the shoji screen 2, and an opening / closing device 4 that opens and closes the shoji screen 2. The shoji screen 2 is attached to the frame 3 so that it can be opened and closed, and an opening 3A in the frame 3 is opened and closed by the shoji screen 2 that opens and closes.

[0011] When viewing the fitting 1 installed in a building from the front (see Figure 1), the direction that is up and down is the up-down direction R, and the direction that is left and right is the left-right direction S. In Figure 1, the up-down direction R is the vertical direction, and the left-right direction S is the horizontal direction. The indoor-outdoor direction T (see Figures 2 and 3) is the indoor-outdoor direction (indoor-outdoor direction) of the fitting 1 installed in a building. Furthermore, the indoor-outdoor direction T is the front-to-back direction (depth direction) and the thickness direction of the shoji screen 2 when viewing the fitting 1 installed in a building from the front, and in Figure 3 it is the horizontal direction perpendicular to the left-to-right direction S. In this way, the directions related to the fitting 1 are specified by the directions when it is installed in a building. Furthermore, the indoor side and outdoor side of the fitting 1 are the indoor side and outdoor side when it is installed in a building.

[0012] The frame body 3 is a rectangular opening frame (window frame) and is installed in an opening in a building. The frame body 3 has four frames 10-13 (an upper frame 10, a lower frame 11, and a pair of vertical frames 12, 13) that are combined with each other, and the four frames 10-13 form a rectangular opening 3A. The frames 10-13 are frame materials that make up the frame body 3, and each is made of a shaped member (extruded shape) formed by extrusion molding. The upper frame 10 and the lower frame 11 are upper and lower horizontal frames of the frame body 3, and extend in the horizontal direction (left-right direction S) at the top and bottom of the frame body 3. The pair of vertical frames 12, 13 are side frames located on the left and right sides of the frame body 3, and extend in the vertical direction (up-down direction R) at the sides of the frame body 3. The upper frame 10, the lower frame 11, and the left and right vertical frames 12, 13 are connected at their ends to form the frames 10-13.

[0013] The shoji screen 2 is an opening / closing body that can be opened and closed, and has a rectangular frame 20 and a panel 21 arranged inside the frame 20. The frame 20 has four frames 22 to 25 (an upper frame 22, a lower frame 23, and a pair of vertical frames 24, 25) that are combined with each other. The frames 22 to 25 are frame materials that make up the frame 20, and each is made of shaped material (extruded shaped material) formed by extrusion molding. The upper frame 22 and the lower frame 23 are horizontal frames on the top and bottom of the frame 20, and extend horizontally at the top and bottom of the frame 20. The pair of vertical frames 24, 25 are side frames located on the left and right sides of the frame 20, and extend vertically on the sides of the frame 20. The ends of the upper frame 22, the lower frame 23, and the left and right vertical frames 24, 25 are connected to form a frame of the frames 22 to 25. The panel 21 is glass (for example, double glazing) that is fitted into the frame 20 and held by the frame 20 and the frames 22 to 25.

[0014] The opening and closing device 4 has a rotatable handle 4A, is attached to the frame 3, and is connected to the shoji screen 2. Here, the opening and closing device 4 is attached to the bottom frame 11 of the frame 3 and connected to the bottom stile 23 of the frame body 20 of the shoji screen 2. The handle 4A is located on the indoor side of the bottom frame 11 and protrudes toward the indoor side. When opening or closing the shoji screen 2, the handle 4A is rotated to operate an interlocking mechanism (not shown) of the opening and closing device 4. The interlocking mechanism applies a force to the shoji screen 2 in the opening and closing directions (opening direction and closing direction) in conjunction with the rotation of the handle 4A. The opening and closing device 4 rotates and moves the shoji screen 2 in both the opening and closing directions in conjunction with the rotation of the handle 4A. As a result, the shoji screen 2 moves (rotates) toward the outdoor side and the frame 3 side (indoor side) to open and close. The connection of the opening and closing device 4 to the shoji screen 2 can be released. By disconnecting the opening and closing device 4 from the shoji screen 2, the shoji screen 2 can be manually moved and opened / closed without using the opening and closing device 4.

[0015] FIG. 4 is a vertical cross-sectional view showing the state in which the shoji screen 2 of the fitting 1 of this embodiment is open, and shows the state in which the shoji screen 2 is manually opened. As shown in the figure, the fitting 1 is equipped with a support mechanism 5 that supports a shoji screen 2 so that it can be opened and closed. The support mechanism 5 is attached to the upper parts of the vertical frames 12, 13 of the frame body 3 and to the upper part of the shoji screen 2 (frame body 20), rotatably supporting the upper part of the shoji screen 2 and connecting the upper part of the shoji screen 2 to the frame body 3. The shoji screen 2 moves by rotating around the upper part supported by the support mechanism 5. In doing so, the lower part of the shoji screen 2 moves toward the outside and the frame body 3 relative to the upper part of the shoji screen 2, causing the shoji screen 2 to rotate.

[0016] The shoji screen 2 is placed inside the frame 3 (at the opening 3A), and rotates around the top to move between the outside and the frame 3 to open and close. When opening and closing, the shoji screen 2 moves in the closing and opening directions to be located at a closed position P1 (see Figure 2) and an open position P2 (see Figure 4). The closed position P1 of the shoji screen 2 is the position where the shoji screen 2 is located when the shoji screen 2 is closed (fully closed position), and the open position P2 of the shoji screen 2 is the position where the shoji screen 2 is located when the shoji screen 2 is opened (fully open position). The shoji screen 2 moves between the closed position P1 and the open position P2 by rotating.

[0017] The shoji screen 2 moves (rotates) from the open position P2 toward the closed position P1 inside the frame body 3 to close, and is positioned at the closed position P1. When the shoji screen 2 is completely closed, it is positioned at the closed position P1, and the opening 3A of the frame body 3 is closed by the shoji screen 2 in the closed position P1. The shoji screen 2 moves from the closed position P1 toward the open position P2 outside (towards the outdoors) of the frame body 3 to open, and is positioned at the open position P2. The open position P2 is a position closer to the outdoors than the closed position P1. When the shoji screen 2 is completely open, it is positioned at the open position P2, and the opening 3A of the shoji screen 2 and the frame body 3 are opened. In contrast, when the opening and closing device 4 is connected to the shoji screen 2, the opening and closing device 4 restricts the movement and opening of the shoji screen 2.

[0018] FIG. 5 is a vertical cross-sectional view showing a state in which the opening of the shoji screen 2 of the fitting 1 of this embodiment is restricted, and shows a state in which the shoji screen 2 is opened by the opening and closing device 4. As shown in the figure, the fitting 1 is equipped with an arm 6 connected to a frame 3 and a shoji screen 2 (here, the frame 20 of the shoji screen 2). The arm 6 is provided on the opening and closing device 4, constitutes part of the interlocking mechanism of the opening and closing device 4, and is rotatably attached to the frame 3. In conjunction with the rotation of the handle 4A, the opening and closing device 4 moves the arm 6 of the interlocking mechanism between the outside and the frame 3 side, and the arm 6 moves (rotates) the shoji screen 2 to open or close it. The arm 6 is a connecting arm connected to the bottom frame 11 of the frame 3 and the bottom frame 23 of the frame 20 of the shoji screen 2.

[0019] The opening and closing device 4 is connected to the bottom frame 23 of the shoji screen 2 by an arm 6, and moves the bottom frame 23 of the shoji screen 2 between the outdoor side and the bottom frame 11 side of the frame 3 (indoor side), thereby moving and opening the shoji screen 2. The arm 6 of the opening and closing device 4 is a restricting member that restricts the movement and opening of the shoji screen 2, and restricts the movement and opening of the shoji screen 2 at a restricting position P3. The restricting position P3 is an intermediate position between the closed position P1 and the open position P2, and is a position on the outdoor side of the closed position P1 and on the frame 3 side (indoor side) of the open position P2. The opening and closing device 4 moves (rotates) the shoji screen 2 between the closed position P1 and the restricting position P3 by the arm 6 to open and close it, and restricts the opening of the shoji screen 2 between the closed position P1 and the open position P2.

[0020] When opening the shoji screen 2, the opening and closing device 4 moves the arm 6 from the bottom frame 11 of the frame body 3 toward the outdoor side, and the arm 6 moves the shoji screen 2 in the opening direction from the closed position P1 to the limiting position P3, thereby placing the shoji screen 2 at the limiting position P3. At this time, the arm 6 gradually protrudes from the bottom frame 11 of the frame body 3 toward the outdoor side, gradually moving the shoji screen 2 toward the outdoor side. When closing the shoji screen 2, the opening and closing device 4 moves the arm 6 from the outdoor side of the bottom frame 11 of the frame body 3 toward the bottom frame 11, and the arm 6 moves the shoji screen 2 in the closing direction from the limiting position P3 to the closed position P1, thereby placing the shoji screen 2 at the closed position P1. At this time, the arm 6 is gradually pulled back toward the bottom frame 11 on the indoor side, gradually moving the shoji screen 2 toward the indoor side. When the shoji screen 2 is placed at the closed position P1, the arm 6 is positioned along the bottom frame 11 of the frame body 3 and the bottom stile 23 of the frame body 20.

[0021] The arm 6 restricts the movement of the shoji screen 2 in the opening direction at the restricting position P3, and the shoji screen 2 stops at the restricting position P3. As a result, the movement of the shoji screen 2 in the opening direction and the opening are restricted at the restricting position P3, and the movement of the shoji screen 2 beyond the restricting position P3 toward the open position P2 and the opening are restricted. The arm 6 also prevents the movement of the shoji screen 2 from the restricting position P3 toward the open position P2, and prevents the shoji screen 2 from moving to the open position P2 and opening. The opening and closing device 4 restricts the opening degree of the shoji screen 2 by the arm 6, and moves and opens and closes the shoji screen 2 within the opening degree from the closed position P1 to the restricting position P3.

[0022] Fig. 6 is a plan view showing the shoji screen 2 to which the arm 6 of the fitting 1 of this embodiment is connected, and Fig. 7 is a plan view showing the shoji screen 2 to which the arm 6 of the fitting 1 of this embodiment is disconnected. Figs. 6 and 7 show a part of the bottom frame 23 of the shoji screen 2 and the part of the arm 6 on the shoji screen 2 side as viewed from above. As shown in the figure, the fitting 1 comprises an attachment part 30 provided on the shoji screen 2, a connecting member 40 that can connect and disconnect the arm 6 to the shoji screen 2, and an operating part 50 that is operated by the user. The attachment part 30 is an attachment member fixed to the shoji screen 2 (here, the bottom frame 23 of the frame body 20) and protrudes from the bottom frame 23 towards the indoor side. The attachment part 30, connecting member 40, and operating part 50 are located on the indoor side of the shoji screen 2, and the connecting member 40 and operating part 50 are attached to the attachment part 30.

[0023] The connecting member 40 is provided on the shoji screen 2 and connects the arm 6 to the shoji screen 2, and is capable of releasing the connection of the arm 6 to the shoji screen 2. The connecting member 40 is rotatably supported by a shaft 41, and is rotatably attached to the mounting part 30 by the shaft 41. The operating part 50 is a part (operating member) for operating the connection and release of the arm 6 to the shoji screen 2, and is used to operate the connection and release of the arm 6 to the shoji screen 2 by the connecting member 40. The operating part 50 has a shaft 51, and is rotatably attached to the mounting part 30 by the shaft 51. The shafts 41, 51 are attached to the mounting part 30 at a distance from each other in the left-right direction S. The connecting member 40 and the operating part 50 are rotatably connected to the shoji screen 2 by the shafts 41, 51 and the mounting part 30, respectively, and rotate around the shafts 41, 51.

[0024] The connecting member 40 is a connecting arm formed in an arm shape, and has an engaging portion 42 that engages with the operating component 50. The engaging portion 42 is provided at one end (tip end) of the connecting member 40, with the other end (base end) of the connecting member 40 supported by the shaft 41, and is spaced apart from the shaft 41 and the one end of the connecting member 40. When the engaging portion 42 engages with the operating component 50 and is held by the operating component 50, the connecting member 40 extends in the left-right direction S and is arranged along the mounting portion 30, forming an elongated hole portion 43 between the connecting member 40 and the mounting portion 30. The elongated hole portion 43 is located on the outdoor side (shoji screen 2) of the connecting member 40, and extends in the left-right direction S along the mounting portion 30 and the connecting member 40.

[0025] The arm 6 has a connecting protrusion 6A that is connected to the connecting material 40. The connecting protrusion 6A is provided at the tip of the arm 6 on the shoji screen 2 side, and is arranged so as to be able to move inside the elongated hole 43. The connecting protrusion 6A is sandwiched between the mounting part 30 and the connecting material 40, and is connected to the connecting material 40 so that its position inside the elongated hole 43 can be changed in the longitudinal direction of the elongated hole 43 (left-right direction S). When the shoji screen 2 moves (opens or closes), the connecting protrusion 6A moves in the longitudinal direction of the elongated hole 43 along the mounting part 30 and the connecting material 40 while rotating inside the elongated hole 43. The arm 6 pushes the mounting part 30 and the shoji screen 2 in the opening direction (towards the outdoors) with the connecting protrusion 6A to open the shoji screen 2, and pulls the connecting material 40 and the shoji screen 2 in the closing direction (towards the indoors) with the connecting protrusion 6A to close the shoji screen 2.

[0026] The arm 6 is connected to the connecting member 40 by the connecting protrusion 6A, and is connected to the shoji screen 2 via the connecting member 40 and the mounting portion 30. The connecting member 40 holds the connecting protrusion 6A and the arm 6 so that they can rotate and move in the left-right direction S, and connects the connecting protrusion 6A and the arm 6 to the shoji screen 2 via the mounting portion 30. The arm 6 moves in the left-right direction S while rotating relative to the connecting member 40, the mounting portion 30, and the shoji screen 2. When the shoji screen 2 moves, the connecting protrusion 6A and the arm 6 are maintained in a connected state to the shoji screen 2 by the connecting member 40.

[0027] The operation component 50 is a rotatable holding component that holds the connecting member 40, and has a holding portion 52 that holds the connecting member 40, and a switching portion 53 that is used to switch the operation component 50. The holding portion 52 is a recess that opens toward the connecting member 40. The engagement portion 42 of the connecting member 40 is disposed inside the holding portion 52 and engages with the holding portion 52. When the arm 6 is connected to the shoji screen 2 by the connecting member 40, the operation component 50 holds the engagement portion 42 and the connecting member 40 by the holding portion 52. The switching portion 53 is an operating portion for operating (switching) the operation component 50, and is a knob (protrusion) in this case. The state of the operation component 50 can be switched by pinching the switching portion 53 and rotating the operation component 50 together with the switching portion 53.

[0028] The switching unit 53 is used to switch the operation element 50 between a maintained state F1 (the state shown in FIG. 6) and a released state F2 (the state shown in FIG. 7). The maintained state F1 of the operation element 50 is a state in which the operation element 50 maintains the connection of the arm 6 to the shoji screen 2 by the connecting member 40, and the released state F2 of the operation element 50 is a state in which the operation element 50 can release the connection of the arm 6 to the shoji screen 2 by the connecting member 40. The maintained state F1 of the operation element 50 is a state in which the holding portion 52 holds the engaging portion 42 and the connecting member 40, and the released state F2 of the operation element 50 is a state in which the holding portion 52 releases the holding of the engaging portion 42 and the connecting member 40. The switching unit 53 rotates the operation element 50 between the maintained state F1 (maintained position) and the released state F2 (released position) to switch between the maintained state F1 and the released state F2. Using the switching unit 53, the operating component 50 is operated to switch between a state F1 in which the arm 6 maintains its connection to the shoji screen 2 via the connecting material 40, and a state F2 in which the arm 6 is released from its connection to the shoji screen 2 via the connecting material 40.

[0029] The user operates the operation component 50 using the switching unit 53, switching the operation component 50 between a maintained state F1 and a released state F2. The operation component 50 also operates to connect the arm 6 to the shoji screen 2 via the connecting member 40 and to release the connection of the arm 6 to the shoji screen 2 via the connecting member 40. By rotating the operation component 50 from the released state F2 to the maintained state F1 while the arm 6 can be connected to the shoji screen 2 via the connecting member 40, the operation component 50 is switched from the released state F2 to the maintained state F1. As a result, the engaging portion 42 of the connecting member 40 fits into the holding portion 52 of the operation component 50, and the engaging portion 42 engages with the holding portion 52. The operation component 50 also holds the connecting member 40, connecting the arm 6 to the connecting member 40 and the shoji screen 2.

[0030] The operating component 50 causes the connecting member 40 to maintain the connection of the arm 6 to the shoji screen 2 by the holding portion 52. The arm 6 is maintained in a state connected to the connecting member 40 and the shoji screen 2 by the operating component 50. In this state, the shoji screen 2 moves only between the closed position P1 and the limiting position P3 to open and close. Furthermore, by moving the shoji screen 2 in the opening direction, the shoji screen 2 moves from the closed position P1 to the limiting position P3, and the opening of the shoji screen 2 is limited at the limiting position P3, and the shoji screen 2 is opened at the limiting position P3. The arm 6 prevents the shoji screen 2 from moving between the limiting position P3 and the open position P2, and prevents the shoji screen 2 from opening to the open position P2.

[0031] With the arm 6 connected to the shoji screen 2 by the connecting member 40, the operating component 50 is switched from the maintained state F1 to the released state F2 by rotating the operating component 50 from the maintained state F1 to the released state F2. This causes the holding portion 52 of the operating component 50 to disengage from the engaging portion 42 of the connecting component 40, and the engagement of the engaging portion 42 with the holding portion 52 is released. In addition, the holding of the connecting component 40 by the operating component 50 is released, making it possible to release the connection of the arm 6 to the connecting component 40 and the connection of the arm 6 to the shoji screen 2 by the connecting member 40.

[0032] In this way, the release state F2 of the operation part 50 is a state in which the connection of the arm 6 to the shoji screen 2 by the connecting member 40 can be released. In this state, by moving the shoji screen 2 in the opening direction, the connecting member 40 is pulled toward the interior by the connecting projection 6A and the arm 6, rotates toward the interior, and detaches from the operation part 50. At the same time, the connecting projection 6A and the arm 6 detach from the connecting member 40, and the connection of the arm 6 to the shoji screen 2 by the connecting member 40 is released.

[0033] By operating the operating part 50, the connecting member 40 is caused to release the connection of the arm 6 to the shoji screen 2. In this state, the shoji screen 2 moves between the closed position P1 and the open position P2 to open and close. Furthermore, by moving the shoji screen 2 in the opening direction, the shoji screen 2 moves from the closed position P1 past the limiting position P3 to the open position P2, and is opened at the open position P2. When connecting the arm 6 to the shoji screen 2, the shoji screen 2 is moved to a position closer to the closed position P1 than the limiting position P3, and the operating part 50 is switched from the release state F2 to the maintenance state F1 in a state where the arm 6 can be connected to the shoji screen 2 by the connecting member 40. As a result, the connecting member 40 is held by the operating part 50, and the arm 6 is connected to the shoji screen 2 by the connecting member 40.

[0034] 8 and 9 are perspective views showing the periphery of the connecting material 40 in the shoji screen 2 of the fitting 1 of this embodiment. As shown in the figure, the fitting 1 is equipped with a detachable restricting component 60 that restricts the operation of the operating component 50. The restricting component 60 is located on the indoor side of the shoji screen 2. The mounting portion 30, the connecting member 40, the operating component 50, and the restricting component 60 constitute a connecting mechanism that connects the arm 6 to the shoji screen 2. The mounting portion 30, the connecting member 40, the operating component 50, the restricting component 60, and the connecting mechanism are provided on the shoji screen 2 and move integrally with the shoji screen 2.

[0035] The restricting member 60 is a restricting material (attaching member) that is removably attached to the operation member 50, and is attached to the operation member 50 while covering the operation member 50. The restricting member 60 is also attached to the operation member 50 in the maintained state F1, and restricts the operation member 50 from switching from the maintained state F1 to the released state F2 (see FIG. 9 ). The restricting member 60 fixes the operation member 50 in the maintained state F1, restricts the switching operation of the operation member 50, and holds the operation member 50 in the maintained state F1. The restricting member 60 prevents the operation member 50 from switching from the maintained state F1 to the released state F2, and maintains the arm 6 connected to the shoji screen 2 by the connecting member 40.

[0036] The restricting component 60 is detachable from the operation component 50. When the operation component 50 is switched from the maintained state F1 to the released state F2, the restricting component 60 is detached from the operation component 50 in the maintained state F1, thereby releasing the fixation of the operation component 50 in the maintained state F1 (see FIG. 8). By removing the restricting component 60, the restriction on the switching operation of the operation component 50 is released, and the operation component 50 can be switched from the maintained state F1 to the released state F2. Thereafter, by switching the operation component 50, the connection of the arm 6 to the shoji screen 2 by the connecting member 40 can be released.

[0039] As shown in the figure, the regulating component 60 has an upper plate portion 61 located on the upper surface, a lower plate portion 62 located on the lower surface, a protrusion portion 63 protruding upward from the lower plate portion 62, a side wall portion 64 located between the upper plate portion 61 and the lower plate portion 62, a clamping portion 65 that clamps the operation component 50, a locking portion 66 that locks with the operation component 50, a contact portion 67 that contacts the shoji screen 2, and a fixing portion 68 that fixes the operation component 50. The upper plate portion 61 is a covering portion that covers the operation component 50 from above, and is placed on the operation component 50. The upper plate portion 61 is positioned above the operation component 50 and contacts the operation component 50 from above.

[0040] The lower plate portion 62 is spaced downward from the upper plate portion 61 and is disposed below the operating component 50, and contacts the operating component 50 from below. The protrusion portion 63 is located between the upper plate portion 61 and the lower plate portion 62, and is disposed on the shoji 2 side (outdoor side) of the operating component 50, and contacts at least the operating component 50. The side wall portion 64 is connected to the edges of the upper plate portion 61 and the lower plate portion 62, and is disposed along the up-down direction R, and contacts the operating component 50 from the side.

[0041] The clamping portion 65 is a portion including the upper plate portion 61, the lower plate portion 62, and the side wall portion 64 of the regulating component 60, and is formed into a concave shape by the upper plate portion 61, the lower plate portion 62, and the side wall portion 64. The clamping portions 65 are disposed above and below the operation component 50, and the upper plate portion 61 and the lower plate portion 62 clamp the operation component 50 including the shaft member 51 in the vertical direction R. The operation component 50 is positioned between the upper plate portion 61 and the lower plate portion 62 of the clamping portion 65 in the vertical direction R, and is disposed inside the clamping portion 65. The operation component 50 fits inside the clamping portion 65, and the clamping portion 65 comes into contact with the operation component 50 at multiple points. Here, the clamping portion 65 comes into contact with the operation component 50 from above, below, and sides by the upper plate portion 61, the lower plate portion 62, and the side wall portion 64.

[0042] In the regulating component 60, the side wall portion 64 is located on one side in the left-right direction S, and the locking portion 66 is located on the other side in the left-right direction S. The locking portion 66 is a protrusion that protrudes downward, and is located on the opposite side of the side wall portion 64 in the left-right direction S with respect to the operation component 50. The side wall portion 64 contacts the operation component 50 from one side in the left-right direction S, and the locking portion 66 contacts the operation component 50 from the other side in the left-right direction S. The locking portion 66 is hooked onto and locked to the operation component 50, and is held by the operation component 50. The locking portion 66, which is locked onto the operation component 50, holds the clamping portion 65 in a position where it clamps the operation component 50.

[0043] The locking portion 66 prevents the clamping portion 65 from coming off the operation component 50, and the clamping portion 65 is maintained in a state in which it clamps the operation component 50. In this state, the locking portion 66 restricts movement of the regulating component 60 to one side in the left-right direction S, and the clamping portion 65 restricts movement of the regulating component 60 upward, downward, and to the other side in the left-right direction S. The arm 6 is located below the upper plate portion 61 and the locking portion 66 of the regulating component 60 and is disposed spaced below the upper plate portion 61. The locking portion 66 protrudes downward from the upper plate portion 61 and extends from the upper plate portion 61 to the arm 6, and abuts against the arm 6 while being locked to the operation component 50. Here, the lower end of the locking portion 66 abuts against the upper surface of the arm 6, and the locking portion 66 is locked to the operation component 50 at a location between the upper plate portion 61 and the arm 6.

[0044] The contact portion 67 is the portion of the regulating component 60 that faces the shoji screen 2, and comes into contact with the shoji screen 2 and is pressed down by the shoji screen 2. As the contact portion 67 comes into contact with the shoji screen 2, the contact portion 67 and the regulating component 60 are supported by the shoji screen 2, and the contact portion 67 regulates the movement of the regulating component 60 towards the outdoor side. Furthermore, the regulating component 60 is prevented from rotating together with the operating component 50, and the regulating component 60 is maintained in a state in which it regulates the switching of the operating component 50. The contact portion 67 is arranged along the indoor side of the bottom frame 23 of the shoji screen 2, and comes into contact with the bottom frame 23 of the shoji screen 2 from the indoor side.

[0045] The fixing portions 68 are recesses formed in the upper plate portion 61, which are open toward the indoor side and are disposed on both sides of the switching portion 53 of the operation component 50, facing the outdoor side and in the left-right direction S. The switching portion 53 is disposed inside the fixing portions 68 and fits into the fixing portions 68. The fixing portions 68 come into contact with the switching portion 53 of the operation component 50 in the maintained state F1 to fix the switching portion 53. The restricting component 60 holds the switching portion 53 by the fixing portions 68, preventing the switching portion 53 from moving (rotating), and restricting the switching operation of the operation component 50 using the switching portion 53. The fixing portions 68 of the restricting component 60 restrict switching of the operation component 50 from the maintained state F1 to the released state F2 using the switching portion 53, thereby maintaining the operation component 50 in the maintained state F1. The fixing portions 68 are pressed by the switching portion 53, and the fixing portions 68 restrict movement of the restricting component 60 toward the indoor side and in the left-right direction S.

[0046] When attaching the regulating component 60, the locking portion 66 is positioned above the operation component 50, and while inserting the operation component 50 into the clamping portion 65, the locking portion 66 is moved downward toward the operation component 50. This rotates the regulating component 60, clamping the operation component 50 between the clamping portion 65, and hooking and locking the locking portion 66 onto the operation component 50, thereby attaching the regulating component 60 to the operation component 50. At the same time, the fixing portion 68 fixes the switching portion 53 of the operation component 50, and the contact portion 67 contacts the shoji screen 2. In this state, the locking portion 66 abuts against the arm 6. In this way, the regulating component 60 is attached to the operation component 50 without using any mounting parts such as screws.

[0047] As explained above, in the fitting 1 of this embodiment, the restricting component 60 prevents the restriction on opening of the shoji screen 2 at the restricting position P3 from being accidentally released, improving the safety of the fitting 1. Furthermore, even in fittings that do not have the restricting component 60 already installed in the building, the restricting component 60 can be attached to the operating component 50 without the need for replacing or modifying components, allowing new functions to be added.

[0048] The fixing portion 68 of the restricting component 60 prevents operation using the switching portion 53 of the operating component 50, making it possible to easily prevent the arm 6 from being disconnected from the shoji screen 2. Furthermore, by bringing the contact portion 67 of the restricting component 60 into contact with the shoji screen 2, the restricting component 60 can be stably attached to the operating component 50, and the restricting component 60 can reliably restrict the switching of the operating component 50 from the maintained state F1 to the released state F2.

[0049] By engaging the locking portion 66 of the regulating component 60 with the operation component 50 and bringing it into contact with the arm 6, rattle of the locking portion 66 and the regulating component 60 is suppressed, and the regulating component 60 can be stably attached to the operation component 50. In addition, by supporting the locking portion 66 with the arm 6, it is possible to suppress up and down rattle of the locking portion 66 and the regulating component 60. The clamping portion 65 and the locking portion 66 of the regulating component 60 make it easy to attach the regulating component 60 to the operation component 50, improving the workability of the attachment work of the regulating component 60.

[0050] The contact portion 67 of the regulating component 60 may be brought into contact with a portion other than the bottom frame 23 of the shoji screen 2. The locking portion 66 of the regulating component 60 may be engaged with the operating component 50 in a manner other than by hooking, for example, by being inserted into a locking hole formed in the operating component 50 and locked into the locking hole. The switching portion 53 of the operating component 50 may be a portion other than a knob that can switch the operating component 50.

[0051] In the fitting 1 of this embodiment, the mounting part 30, connecting member 40, operating part 50, and restricting part 60 are provided on the bottom frame 23 of the shoji screen 2, and the arm 6 is connected to the bottom frame 11 of the frame body 3 and the bottom frame 23 of the shoji screen 2. Alternatively, the mounting part 30, connecting member 40, operating part 50, and restricting part 60 may be provided on a part other than the bottom frame 23 of the shoji screen 2, and the arm 6 may be connected to a part other than the bottom frame 11 of the frame body 3 and a part other than the bottom frame 23 of the shoji screen 2. Furthermore, the present invention is not limited to sliding windows, but can also be applied to other outward-opening fittings and fittings other than outward-opening fittings.
