Description

[Technical Field]

[0001] The present invention relates to a fitting equipped with an openable and closable shoji screen and a screen device. [Background technology]

[0002] In a screen device installed on the indoor wall of a building, the screen device is installed above the fittings, and the screen that is extended from the screen device conceals the fittings' shoji screens. Furthermore, storing the screen in the screen device allows light to enter through the shoji screen. However, if the screen covers the entire shoji screen, light cannot enter through the shoji screen, and if the screen covers the upper part of the shoji screen, the lower part of the shoji screen cannot be concealed from the outdoors. Even when opening the shoji screen for ventilation, depending on how it is opened, the shoji screen may interfere with the screen, preventing it from opening. In response to this problem, a head box-lifting blind lifting device has been known in the past, in which a head box is installed between the vertical frames on both sides of a double-pane glass sash, and the head box is raised and lowered between the vertical frames on both sides (see Patent Document 1).

[0003] In the conventional lifting device described in Patent Document 1, multiple tiers of slats are suspended from a head box, and the slats are raised and lowered by raising and lowering the head box, thereby providing privacy through the slats and admitting light through the double-pane sash. However, to conceal the entire double-pane sash with the slats, the head box must be raised to the top of the double-pane sash using the lifting device, and the slats must be pulled up to the top of the double-pane sash using the head box. In contrast, to admit light through the entire double-pane sash, the head box must be lowered to the bottom of the double-pane sash using the lifting device, and the slats must be folded into the bottom of the double-pane sash using the lifting device. Therefore, using the conventional lifting device to provide privacy and admit light through the double-pane sash is time-consuming. Furthermore, the lifting device is installed within the vertical frame, and the structure of the lifting device is complex, which may increase the workload of installing the lifting device on the vertical frame.

[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 a shoji screen that opens and closes, and are installed in openings of a building. The fittings are also installed between the indoor (indoor) and outdoor (outdoor) sides of a building to close the openings of the building. Below, two embodiments of the fittings will be explained using a fitting (window) equipped with a shoji screen that opens toward the indoor side as an example.

[0010] (First embodiment) FIG. 1 is a perspective view showing the fitting 1 of the first embodiment, and FIG. 2 is a front view showing the fitting 1 of the first embodiment. FIGS. 1 and 2 show the fitting 1 installed in a building as viewed from the indoor side. FIG. 3 is a longitudinal cross-sectional view showing the fitting 1 of the first embodiment taken along line X1-X1 in FIG. 2, showing a cross-section of the fitting 1 cut along a plane including the up-down direction R and the indoor-outdoor direction T. FIG. 4 is a transverse cross-sectional view showing the fitting 1 of the first embodiment taken along line X2-X2 in FIG. 2, showing a cross-section of the fitting 1 cut along a plane including the left-right direction S and the indoor-outdoor direction T.

[0011] When viewing the fitting 1 installed in a building from the front (see Figure 2), 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 2, 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 3 and 4) 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) when viewing the fitting 1 installed in a building from the front, and in Figure 4 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] As shown in the figure, the fitting 1 comprises an openable / closable shoji screen 2, a frame 3 surrounding the shoji screen 2, a pair of rails 4 attached to the shoji screen 2, and a screen device 5 connected to 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 rotates. The shoji screen 2 opens toward the indoor side and moves (rotates) between the indoor side and the frame 3 side (outdoor side) to open and close. The shoji screen 2 rotates to move from the indoor side of the frame 3 toward the frame 3 to close, and is positioned inside the frame 3 (at the opening 3A) to close the opening 3A in the frame 3. The shoji screen 2 also rotates to move from the opening 3A in the frame 3 toward the indoor side and open. This opens the shoji screen 2 and the opening 3A in the frame 3, allowing ventilation through the opening 3A in the frame 3 when the shoji screen 2 is opened.

[0013] The fitting 1 is a draped window (tilt-inward / opening window) and the opening and closing direction (how it opens and closes) of the shoji screen 2 can be switched. The shoji screen 2 is a square opening and closing body (tilt-inward / opening shoji screen) and is attached to a frame 3 so that the opening and closing direction can be switched. The opening and closing direction of the shoji screen 2 can be switched between the tilt-inward opening direction and the inward opening opening direction by rotating the handle 2A of the shoji screen 2. By switching the opening and closing direction, the shoji screen 2 opens and closes in the tilt-inward opening direction as a tilt-in shoji screen, and opens and closes in the inward opening opening direction as an inward opening shoji screen.

[0014] The frame body 3 is a rectangular opening frame (window frame) and is installed in an opening of a building. The frame body 3 has four frames 10-12 (an upper frame 10, a lower frame 11, and a pair of vertical frames 12) that are combined with each other, and the four frames 10-12 form a rectangular opening 3A. The frames 10-12 are frame materials that make up the frame body 3, and each is made of a shaped member (extruded shaped member) formed by extrusion molding. The upper frame 10 and the lower frame 11 are the 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 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 ends of the upper frame 10, the lower frame 11, and the left and right vertical frames 12 are connected to form the frames 10-12.

[0015] The shoji screen 2 has a rectangular frame 20 and a transparent panel 21 arranged inside the frame 20. The frame 20 has four frames 22 to 24 (an upper frame 22, a lower frame 23, and a pair of vertical frames 24) that are fitted together. The frames 22 to 24 are frame materials that make up the frame 20, and each is made of shaped material (extruded shapes) 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 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 are connected to form a frame of the frames 22 to 24. The panel 21 is glass (double glazing in this case), fitted into the frame 20, and held by the frame 20 and the frames 22 to 24. Sunlight passes through the panel 21 from the outside to the inside, and lighting is provided by the shoji screen 2.

[0016] The rails 4 and the screen device 5 are located on the indoor side of the shoji screen 2. The rails 4 are guide rails that guide the screen device 5, and are attached to the shoji screen 2 (here, frame 20). The screen device 5 is movably connected to and attached to a pair of rails 4, and is guided by the rails 4 to move in the longitudinal direction of the rails 4. The longitudinal direction of the rails 4 is the direction in which the rails 4 extend, which is the up-down direction R in this case. The rails 4 extend in the up-down direction R, and guide the screen device 5 to move in the up-down direction R.

[0017] The rails 4 are located on the indoor side of the left and right vertical frames 24 of the frame body 20, and are attached to each of the left and right vertical frames 24. For each of the left and right vertical frames 24, the rails 4 protrude from the vertical frame 24 to the indoor side, are arranged along the vertical frame 24, and extend in the longitudinal direction (up-down direction R) of the vertical frame 24. The left and right ends of the screen device 5 are movably connected to the left and right rails 4, and the screen device 5 is guided by the left and right rails 4 to move in the longitudinal direction of the vertical frame 24.

[0018] The screen device 5 is movably connected to the left and right vertical frames 24 and the shoji screen 2 by the rail 4, and moves integrally with the shoji screen 2 as the shoji screen 2 opens and closes. When the shoji screen 2 is open and when it is closed, the screen device 5 moves along the rail 4 and stops at each position in the longitudinal direction of the rail 4. The screen device 5 also moves in a movable portion between one end of the rail 4 and a portion spaced apart from the end, and is stopped and held at each position in the movable portion of the rail 4. In this case, the one end of the rail 4 is the upper end, and the movable portion of the rail 4 is the portion between the upper end of the rail 4 and the portion where the handle 2A is located. The screen device 5 moves and stops above the handle 2A.

[0019] The screen device 5 has a box 30, a rotatable winding shaft 31 housed inside the box 30, a screen 32 that is movable (raise and lower) inside the shoji screen 2, an operating mechanism 33 that controls the movement of the screen 32, and a pair of stopping devices 6 that stop the screen device 5. The box 30 is a box-shaped case that extends in the left-right direction S. The winding shaft 31 is rotatably supported inside the box 30 and rotates in both directions around its axis. The axis of the winding shaft 31 is the center of rotation of the winding shaft 31, and the axes of the winding shaft 31 and the winding shaft 31 extend in the left-right direction S within the box 30.

[0020] The screen 32 is a covering body that covers the shoji screen 2 and has a sheet-like member (for example, a sheet or a netting material). One end of the screen 32 is attached to the winding shaft 31, and the screen 32 is wound up on the winding shaft 31. The screen 32 is wound up on the winding shaft 31 by rotating the winding shaft 31 in one direction and stored inside the box 30. The screen 32 is also unwound from the winding shaft 31 and the box 30 by rotating the winding shaft 31 in the other direction. As the winding shaft 31 rotates, the screen 32 moves up and down in the vertical direction R between the left and right rails 4. The lower end of the screen 32 is movably connected to the left and right rails 4. The screen 32 moves while being guided by the left and right rails 4, and unfolds along the shoji screen 2 between the left and right rails 4.

[0021] The screen device 5 stores and unwinds the screen 32 by rotating the winding shaft 31. The screen 32 moves in and out of the box 30, and also moves up and down in the vertical direction R. The left and right rails 4 guide the lower end of the screen 32 in the vertical direction R as the screen 32 moves. The operating mechanism 33 is operated by the user to rotate the winding shaft 31 in one direction and the other direction to operate the movement of the screen 32.

[0022] When storing the screen 32, the operating mechanism 33 rotates the winding shaft 31 in one direction in response to a user operation, and the screen 32 is wound up onto the winding shaft 31 so that it can be unwound. As a result, the screen 32 is wound up towards the box 30, moves upward, and is stored inside the box 30. When unwinding the screen 32, the operating mechanism 33 rotates the winding shaft 31 in the other direction in response to a user operation, and the screen 32 is unwound from the winding shaft 31. As a result, the screen 32 is unwound from the box 30 and moves downward. The screen 32 is unwound and deployed along the shoji screen 2, and is arranged along the shoji screen 2. The screen 32, which is arranged on the indoor side of the shoji screen 2, covers the panel 21 of the shoji screen 2.

[0023] The fitting 1 is equipped with a stop device 6 provided on the screen device 5. The stop devices 6 are attached to the left and right ends of the box 30 and are located at the left and right ends of the screen device 5. The stop devices 6 are stopper devices located on the indoor side of the shoji screen 2 and rail 4, and are engaged with the rail 4 to stop the screen device 5 as it moves along the rail 4. The screen device 5 is held on the rail 4 by the stop device 6. The stop device 6 holds the screen device 5 in a stopped position after it has moved, maintaining the screen device 5 in a stopped state.

[0024] Fig. 5 is a front view showing the fitting 1 of the first embodiment with the screen 32 unfolded, and Fig. 6 is a cross-sectional view showing the fitting 1 of the first embodiment taken along line X3-X3 in Fig. 5. Fig. 7 is a front view showing the fitting 1 of the first embodiment with the screen device 5 moved, and Fig. 8 is a cross-sectional view showing the fitting 1 of the first embodiment taken along line X4-X4 in Fig. 7. Figs. 5 and 7 show the fitting 1 installed in a building as seen from the indoor side.

[0025] As shown in the figure, the screen device 5 moves in the up-down direction R along the left and right rails 4 and is held in a stopped position by the left and right stop devices 6. The screen device 5 also moves to the upper end of the rails 4 and is held at the upper end of the rails 4, which is the stopped position, by the stop devices 6 (see FIG. 5). When the shoji screen 2 is in the open state and when the shoji screen 2 is in the closed state, the screen 32 is guided by the left and right rails 4 and unfolded from the box 30 of the screen device 5 to the lower end of the rails 4. As a result, the screen 32 unfolds over the entire panel 21 of the shoji screen 2 and covers the entire panel 21 of the shoji screen 2. The screen 32 conceals the panel 21 on the shoji screen 2. At the same time, opening the shoji screen 2 allows ventilation in the fitting 1.

[0026] The screen device 5 moves from the upper end of the rail 4 to the middle part of the rail 4 in the longitudinal direction (the part between the upper and lower ends), and is held at the middle part of the rail 4, which is the stopping position, by the stop device 6 (see Figure 7). In this state, the screen 32 unfolds at the lower part of the panel 21 of the shoji screen 2 (the part from the middle part to the lower part of the rail 4) and covers the lower part of the panel 21 of the shoji screen 2. The screen 32 conceals the lower part of the panel 21 of the shoji screen 2. At the same time, sunlight passing through the panel 21 allows lighting to enter the upper part of the panel 21 of the shoji screen 2 (the part from the middle part to the upper part of the rail 4). In addition, by opening the shoji screen 2, ventilation in the fitting 1 is possible.

[0027] 9 is a longitudinal cross-sectional view showing the rail 4 and the stop device 6 of the fitting 1 of the first embodiment taken along line X5-X5 in FIG. 2, and shows the upper part including the upper end of the rail 4. FIGS. 10 and 11 are cross-sectional views showing the rail 4 and the stop device 6 of the fitting 1 of the first embodiment taken along line X6-X6 in FIG. 9, and show the end of the box 30 of the screen device 5.

[0028] As shown in the figure, the rail 4 has guide portions 4A and 4B that guide the screen device 5 and a locking portion 4C that locks the stop device 6. Here, two guide portions 4A and 4B (a first guide portion 4A and a second guide portion 4B) are formed on the rail 4. The guide portions 4A and 4B are groove portions (guide groove portions) that extend in the longitudinal direction of the rail 4 and are open toward the screen device 5 in the left-right direction S. The two guide portions 4A and 4B extend parallel to each other and spaced apart in the indoor-outdoor direction T, which is the thickness direction of the shoji screen 2. The first guide portion 4A is an indoor-side guide portion located on the indoor side (the stop device 6 side) of the second guide portion 4B, and the second guide portion 4B is an outdoor-side guide portion located on the outdoor side (the shoji screen 2 side) of the first guide portion 4A.

[0029] The locking portion 4C of the rail 4 is a wall portion (locking wall portion) that protrudes toward the screen device 5 in the left-right direction S, and is arranged along the left-right direction S. The locking portion 4C is adjacent to the stop device 6 in the indoor-outdoor direction T, and the stop device 6 is locked to the locking portion 4C, causing the stop device 6 to stop the screen device 5. The locking portion 4C also has an opposing surface portion 4D that faces the stop device 6, and the stop device 6 is locked to the opposing surface portion 4D. The opposing surface portion 4D is an indoor surface portion of the locking portion 4C that is located on the indoor side, and is arranged along the left-right direction S. The locking portion 4C and the opposing surface portion 4D extend in the longitudinal direction of the rail 4. The opposing surface portion 4D is formed in a flat shape and is arranged facing the indoor side.

[0030] Of the two guide portions 4A, 4B, the first guide portion 4A on the stop device 6 side is located on the outdoor side (the shoji screen 2 side) of the locking portion 4C. The locking portion 4C is a wall portion (opposing wall portion) that faces the stop device 6 in the indoor-outdoor direction T, and is also a wall portion (the groove wall portion of the first guide portion 4A that is a guide groove portion) that is located on the indoor side (the stop device 6 side) of the first guide portion 4A. The guide portions 4A, 4B, the locking portion 4C, and the opposing surface portion 4D are located on the indoor side (the stop device 6 side) of the shoji screen 2, the outdoor side (the shoji screen 2 side) of the stop device 6, and between the shoji screen 2 and the stop device 6 in the indoor-outdoor direction T.

[0031] The screen unit 5 has connecting portions 5A and 5B that are movably connected to the rail 4. Here, the two connecting portions 5A and 5B (first connecting portion 5A and second connecting portion 5B) are provided at the ends of the box 30 of the screen unit 5. The connecting portions 5A and 5B are plate-shaped protrusions (connecting protrusions) provided at the left and right ends of the screen unit 5, respectively, and protrude toward the rail 4 in the left-right direction S. The two connecting portions 5A and 5B are formed parallel to each other and spaced apart from each other in the indoor-outdoor direction T. The first connecting portion 5A is an indoor-side connecting portion located on the indoor side (the side of the stop device 6) of the second connecting portion 5B, and the second connecting portion 5B is an outdoor-side connecting portion located on the outdoor side (the side of the shoji screen 2) of the first connecting portion 5A.

[0032] The connecting portions 5A and 5B of the screen unit 5 are guided portions that are guided by the guide portions 4A and 4B of the rail 4, and protrude toward the guide portions 4A and 4B. The connecting portions 5A and 5B are inserted inside the guide portions 4A and 4B and are arranged movably within the guide portions 4A and 4B. As a result, the first connecting portion 5A is movably connected to the first guide portion 4A, and the second connecting portion 5B is movably connected to the second guide portion 4B. The screen unit 5 is movably connected to the left and right guide portions 4A and 4B and the left and right rails 4 by the left and right connecting portions 5A and 5B. The connecting portions 5A and 5B and the screen unit 5 move while being guided by the guide portions 4A and 4B in the longitudinal direction (up and down direction R) of the guide portions 4A and 4B and the rail 4.

[0033] The stopping device 6 has a base part 40, a movable movable material 50 that is engaged with the engaging part 4C of the rail 4, a biasing means 7 that biases the movable material 50 toward the engaging part 4C, two links 41 and 42 that move the movable material 50, an operating member 43 that controls the movement of the movable material 50, and a cover 44 that covers the parts of the stopping device 6 other than the operating member 43. The base part 40 has a storage part 40A that stores the movable material 50, and is fixed to an end of the box 30 of the screen device 5.

[0034] The movable material 50 is movably held by the base portion 40, and slides and moves in the indoor / outdoor direction T between a position inside the storage portion 40A and a position outside the storage portion 40A. The biasing means 7 is a spring that is an elastic material that can be elastically deformed, and is located on the indoor side of the movable material 50. In this example, the biasing means 7 is a compression coil spring, and two biasing means 7 are provided between the movable material 50 and the base portion 40. The movable material 50 is biased by the biasing means 7 toward the outdoor side, which is the outside side of the storage portion 40A, and toward the locking portion 4C of the rail 4.

[0035] The movable material 50 is a latch that is latched by the latch portion 4C of the rail 4, and moves between a latch position P1 (see FIGS. 9 and 10) where it is latched by the latch portion 4C and a separated position P2 (see FIG. 11) where it is separated from the latch portion 4C. The latch position P1 is a position (a position outside the storage section 40A) where the movable material 50 is latched by the latch portion 4C and held by the latch portion 4C, and the separated position P2 is a position (a position inside the storage section 40A) where the movable material 50 is separated from the latch portion 4C and is released from the latch portion 4C. The movable material 50 moves from the latch position P1 toward the indoor side to the separated position P2 and is positioned at the separated position P2, and then moves from the separated position P2 toward the outdoor side to the latch position P1 and is positioned at the latch position P1.

[0036] The stop device 6 and the movable material 50 are located on the opposite side of the shoji screen 2 with respect to the locking portion 4C and the opposing surface portion 4D. When the movable material 50 at the locking position P1 is locked by the locking portion 4C, the movable material 50, the stop device 6, and the screen device 5 are stopped and held in the stopped position. The movable material 50 and the stop device 6 are held and stopped by the locking portion 4C, and the screen device 5 is held and stopped by the locking portion 4C via the movable material 50 and the stop device 6. Furthermore, when the movable material 50 moves from the locking position P1 to the separated position P2, the hold of the movable material 50, the stop device 6, and the screen device 5 at the stopped position is released, and the stop device 6 and the screen device 5 can move along the rail 4.

[0037] The biasing means 7 biases the movable material 50 from the separated position P2 toward the locking position P1, placing the movable material 50 at the locking position P1. The biasing force of the biasing means 7 holds the movable material 50 at the locking position P1, restricting movement of the movable material 50 from the locking position P1 to the separated position P2. When moving the stop device 6 and the screen device 5 along the rail 4, the movable material 50 is moved from the locking position P1 to the separated position P2 against the biasing force of the biasing means 7, and the movable material 50 is separated from the locking portion 4C. This releases the locking of the movable material 50 to the locking portion 4C, and the stop and holding of the screen device 5 by the stop device 6 is released. In this state, the stop device 6 and the screen device 5 are moved, and the stop device 6 stops and holds the screen device 5 again at the stop position to which it was moved.

[0038] On the indoor side of the shoji screen 2, the first connecting portion 5A of the screen unit 5 is located on the outdoor side (shoji screen 2 side) of the locking portion 4C, and the locking portion 4C and the opposing surface portion 4D of the rail 4 are arranged between the stop device 6 and the movable material 50. The first connecting portion 5A moves along the locking portion 4C inside the first guide portion 4A of the rail 4, while being guided by the first guide portion 4A. In the indoor-outdoor direction T, the locking portion 4C and the opposing surface portion 4D face the stop device 6 and the movable material 50, and are arranged between the stop device 6 and the first connecting portion 5A, and between the movable material 50 and the first connecting portion 5A. The locking portion 4C faces the movable material 50 and the first connecting portion 5A, respectively. The stop device 6 and the movable material 50 are located on the indoor side of the locking portion 4C and the opposing surface portion 4D, and move in the longitudinal direction of the rail 4 along the locking portion 4C and the opposing surface portion 4D when the screen unit 5 moves.

[0039] The movable member 50 is positioned at the locking position P1, with the locking portion 4C and the opposing surface 4D positioned between it and the first connecting member 5A, and is pressed against the opposing surface 4D of the locking portion 4C by the biasing means 7. In this state, the movable member 50 is biased by the biasing means 7 to sandwich the locking portion 4C between itself and the first connecting member 5A, and is locked to the opposing surface 4D of the locking portion 4C. Furthermore, the first connecting member 5A is positioned at the movable member 50, with the locking portion 4C and the opposing surface 4D positioned between itself and the movable member 50. In the first guide member 4A, the first connecting member 5A is locked to the locking portion 4C, with the locking portion 4C sandwiched between itself and the movable member 50 at the locking position P1.

[0040] The movable member 50 has a contact portion 51 that contacts the locking portion 4C and the opposing surface portion 4D. The contact portion 51 is an end portion on the outdoor side (locking portion 4C side) of the movable member 50, and is pressed against the locking portion 4C and the opposing surface portion 4D. The contact portion 51 is provided with a slippage prevention material (e.g., rubber) that prevents slippage relative to the locking portion 4C and the opposing surface portion 4D, and the slippage prevention material of the contact portion 51 contacts the locking portion 4C and the opposing surface portion 4D. The locking portion 4C is sandwiched between the contact portion 51 of the movable member 50 and the first connecting portion 5A. As a result, the contact portion 51 and the movable member 50 are held by the opposing surface portion 4D of the locking portion 4C and are locked to the opposing surface portion 4D of the locking portion 4C. The movable member 50 and the first connecting portion 5A are attached to the locking portion 4C by sandwiching the locking portion 4C between them.

[0041] At any position of the locking portion 4C in the longitudinal direction of the rail 4 (the movement direction of the screen device 5), the movable material 50 is pressed against the opposing surface 4D of the locking portion 4C, and the movable material 50 and the first connecting portion 5A sandwich the locking portion 4C. Furthermore, the movable material 50 is locked to the opposing surface 4D of the locking portion 4C at any position of the locking portion 4C in the longitudinal direction of the rail 4, and is held by the opposing surface 4D of the locking portion 4C at locking position P1. As a result, the stop device 6 and the screen device 5 stop at any position of the locking portion 4C in the longitudinal direction of the rail 4 and are held in the stop position.

[0042] The links 41, 42 (first link 41, second link 42) of the stopping device 6 constitute a link mechanism (here, a slider-crank mechanism) that moves the movable member 50 from the locking position P1 to the separated position P2 against the biasing force of the biasing means 7. The first link 41 is located on the outdoor side (rail 4 side) of the second link 42, and one end 41A on the indoor side of the first link 41 and one end 42A on the outdoor side of the second link 42 are attached to and rotatably connected by a connecting pin 45. In addition, the other end 41B on the outdoor side of the first link 41 is rotatably connected to the base part 40, and the other end 42B on the indoor side of the second link 42 is rotatably connected to the movable member 50. The operating member 43 is rotatably connected to the base part 40, covers the links 41, 42, and comes into contact with a rotatable roller 46. The roller 46 is attached to the connecting pin 45 and is provided at the connecting portion of the links 41, 42 where one end 41A of the first link 41 and one end 42A of the second link 42 are connected.

[0043] When the movable member 50 is disposed at the locking position P1, the first link 41 and the second link 42 approach each other in the indoor / outdoor direction T, and the connecting pin 45 and the roller 46 move away from the movable member 50 in the left-right direction S. The operating member 43 is pushed by the roller 46 in a direction moving away from the movable member 50 in the left-right direction S, and moves away from the movable member 50. From this state, a force in a direction moving toward the movable member 50 is applied to the operating member 43 in the left-right direction S, pushing the operating member 43 toward the movable member 50. This causes the operating member 43 to rotate toward the movable member 50 and move closer to the movable member 50.

[0044] With the position of the other end 41B of the first link 41 fixed, the roller 46 is pushed toward the movable member 50 by the operating member 43 and approaches the movable member 50 together with the connecting pin 45. At the same time, the first link 41 and the second link 42 are displaced toward the indoor side (the opposite side of the rail 4) while rotating, and the other end 42B of the second link 42 moves toward the indoor side together with the movable member 50. The movable member 50 receives a force toward the indoor side from the other end 42B of the second link 42 and moves from the locking position P1 to a separated position P2 on the indoor side.

[0045] When the state in which the operating member 43 is being pressed toward the movable member 50 is released and the force in the direction in which the operating member 43 approaches the movable member 50 is released, the movable member 50 moves from the separated position P2 to the outdoor locking position P1 due to the biasing force of the biasing means 7. At the same time, the other end 42B of the second link 42 moves toward the outdoor side together with the movable member 50, and the connecting pin 45 and roller 46 move away from the movable member 50. The operating member 43 is pushed by the roller 46 in the direction in which it moves away from the movable member 50, and moves away from the movable member 50 by rotating.

[0046] In the fitting 1 described above, the shoji screen 2, rail 4, screen device 5, and stop device 6 make it easy to open the shoji screen 2 for ventilation, let in light through the shoji screen 2, and conceal the shoji screen 2 with the screen 32 of the screen device 5. Furthermore, ventilation, lighting, and privacy can be achieved simultaneously with a simple mechanism. The number of parts for ventilation, lighting, and privacy and the time required to assemble the fitting 1 can be reduced, making it possible to improve the workability of assembling the fitting 1.

[0047] The screen device 5 can be attached to and detached from the rail 4. Therefore, the screen device 5 can be easily replaced, and by replacing the screen device 5, the color or design of the screen 32 can also be easily changed. Even in fittings that do not already have a screen device 5 installed in a building, the rail 4 and screen device 5 can be easily installed without replacing the shoji screen.

[0048] By sandwiching the locking portion 4C of the rail 4 between the movable material 50 and the first connecting portion 5A, the screen device 5 moving along the rail 4 can be stopped at any position in the movable portion of the rail 4, and the screen device 5 can be held at any position in the movable portion of the rail 4. The first guide portion 4A of the rail 4 guides the first connecting portion 5A of the screen device 5, and the first connecting portion 5A connected to the first guide portion 4A and the movable material 50 can stably sandwich the locking portion 4C.

[0049] Regardless of the opening / closing direction (opening / closing method) of the shoji screen 2, ventilation can be achieved by opening the shoji screen 2 toward the indoor side, lighting can be provided by the shoji screen 2, and the indoor side of the shoji screen 2 can be easily concealed by the screen 32 of the screen device 5. The position of the screen device 5 in the vertical direction R can be adjusted by the rail 4 and the stop device 6 extending in the vertical direction R, allowing lighting to be provided at the upper part of the panel 21 of the shoji screen 2, while the screen 32 of the screen device 5 can conceal the lower part of the panel 21 of the shoji screen 2.

[0050] The rail 4 is required to have at least one guide portion (a guide portion corresponding to the first guide portion 4A), and the screen unit 5 is required to have at least one connecting portion (a connecting portion corresponding to the first connecting portion 5A). Therefore, the rail 4 may have only one guide portion or three or more guide portions, and the screen unit 5 may have only one connecting portion or three or more connecting portions. In contrast, the movable member 50 may be locked to the opposing surface portion 4D and the locking portion 4C without sandwiching the locking portion 4C between the movable member 50 and the first connecting portion 5A. In this case, for example, the movable member 50 is pressed against the opposing surface portion 4D and the locking portion 4C by the biasing means 7, and the movable member 50 is locked to the opposing surface portion 4D and the locking portion 4C by friction between the opposing surface portion 4D of the movable member 50 and the locking portion 4C.

[0051] The screen device 5 is not limited to being moved in the up-down direction R, but may also be moved in other directions (for example, the left-right direction S). When the screen device 5 is moved in the left-right direction S, the rail 4 is attached, for example, to the upper frame 22 and the lower frame 23 of the frame body 20 of the shoji screen 2 and extends in the left-right direction S. The fitting 1 is not limited to a window, but may be other fittings equipped with a shoji screen 2. If the fitting 1 is a door, for example, the shoji screen 2 is a door body having a window section, and the screen device 5 is connected to the door body to cover the window section of the door body with the screen 32. Furthermore, the present invention is not limited to draped windows, but can be applied to other fittings, for example, various inward-opening fittings in which the shoji screen opens toward the interior, various outward-opening fittings in which the shoji screen opens toward the exterior, and various sliding fittings in which the shoji screen opens by sliding.

[0052] (Second embodiment) Next, a second embodiment of the fitting 1 will be described. In the fitting 1 of the second embodiment, explanations of the same matters as those in the fitting 1 of the first embodiment will be omitted, and the following will mainly describe matters that differ from the fitting 1 of the first embodiment. Furthermore, in the fitting 1 of the second embodiment, the same names and symbols as those in the fitting 1 of the first embodiment will be used for components that correspond to those in the fitting 1 of the first embodiment.

[0053] Fig. 12 is a perspective view showing the fitting 1 of the second embodiment, and Fig. 13 is a front view showing the fitting 1 of the second embodiment. Figs. 12 and 13 show the fitting 1 installed in a building as viewed from the indoor side. Fig. 14 is a cross-sectional view showing the fitting 1 of the second embodiment taken along line X7-X7 in Fig. 13, showing a cross section of the fitting 1 cut along a plane including the left-right direction S and the indoor-outdoor direction T. Fig. 15 is a cross-sectional view showing the fitting 1 of the second embodiment taken along line X8-X8 in Fig. 13, showing the rail 4, screen device 5, and stop device 6 as viewed from below.

[0054] As shown in the figure, in the fitting 1 of the second embodiment, the locking portions 4C are locking members attached to each of the left and right rails 4, and are provided on the indoor surface of the rails 4, and are arranged facing the indoor side (the stopping device 6 side). The locking portions 4C are provided at multiple locations in the longitudinal direction of the rail 4, and the rail 4 has multiple locking portions 4C. The multiple locking portions 4C are provided at intervals in the longitudinal direction of the rail 4, are spaced apart from each other in the longitudinal direction of the rail 4, and each receives a movable member 50 of the stopping device 6. The movable member 50 of the stopping device 6 is hooked onto the locking portions 4C and locked.

[0055] Fig. 16 is a front view showing the fitting 1 of the second embodiment with the screen 32 unfolded, and Fig. 17 is a cross-sectional view showing the fitting 1 of the second embodiment taken along line X9-X9 in Fig. 16. Fig. 18 is a front view showing the fitting 1 of the second embodiment with the screen device 5 moved, and Fig. 19 is a cross-sectional view showing the fitting 1 of the second embodiment taken along line X10-X10 in Fig. 18. Figs. 16 and 18 show the fitting 1 installed in a building as seen from the indoor side.

[0056] As shown in the figure, the movable member 50 of the stopping device 6 comes into contact with each of the multiple locking portions 4C and is locked to each of the multiple locking portions 4C. The stopping device 6 and the screen device 5 are stopped at the positions of each of the multiple locking portions 4C in the longitudinal direction of the rail 4 and are held in the stopped position by the movable member 50 and the multiple locking portions 4C.

[0057] 20 is a longitudinal cross-sectional view showing the rail 4 and the stop device 6 of the fitting 1 of the second embodiment taken along the line X11-X11 in FIG. 13, and shows the upper part including the upper end of the rail 4. FIGS. 21 and 22 are cross-sectional views showing the rail 4 and the stop device 6 of the fitting 1 of the second embodiment taken along the line X12-X12 in FIG. 20, and show the end of the box 30 of the screen device 5.

[0058] As shown in the figures, in the fitting 1 of the second embodiment, unlike the movable material 50 of the fitting 1 of the first embodiment, the movable material 50 is arranged at the locking position P1 without being pressed against the opposing surface portion 4D and the locking portion 4C by the biasing means 7. In addition, the movable material 50 is locked to the locking portion 4C without sandwiching the locking portion 4C between the movable material 50 and the first connecting portion 5A of the screen device 5.

[0059] The locking portion 4C has a receiving portion 4E that receives the movable member 50, a restricting portion 4F that restricts the movement of the movable member 50, a recess 4G in which the movable member 50 is placed, and two guide portions 4H, 4I (a first guide portion 4H and a second guide portion 4I) that guide the movable member 50. The receiving portion 4E and the restricting portion 4F are spaced apart in the longitudinal direction of the rail 4 and each protrude toward the indoor side (the side of the stopping device 6). The receiving portion 4E is located below the restricting portion 4F, and the restricting portion 4F is located above the receiving portion 4E. The recess 4G is a concave portion formed between the receiving portion 4E and the restricting portion 4F of the locking portion 4C and is open toward the indoor side. The movable member 50 (contact portion 51) at the locking position P1 is placed in the recess 4G and is held within the recess 4G by the receiving portion 4E and the restricting portion 4F.

[0060] The receiving portion 4E and the restricting portion 4F of the locking portion 4C face each other in the longitudinal direction of the rail 4, sandwiching the recess 4G and the movable member 50 therebetween. At the locking position P1, the movable member 50 is placed on the receiving portion 4E from above and comes into contact with the receiving portion 4E. The receiving portion 4E receives the movable member 50 and restricts movement of the movable member 50 in the longitudinal direction of the rail 4 (downward in this case), thereby stopping the movable member 50 and the stopping device 6. When the movable member 50 is arranged at the locking position P1 (arranged in the recess 4G) due to the biasing force of the biasing means 7, it is hooked onto the receiving portion 4E of the locking portion 4C, locked by the receiving portion 4E, and held by the receiving portion 4E and the locking portion 4C.

[0061] In the longitudinal direction of the rail 4, the restricting portion 4F is located on the opposite side of the movable material 50 at the locking position P1 from the receiving portion 4E, and the movable material 50 is disposed between the receiving portion 4E of the rail 4 and the restricting portion 4F. The restricting portion 4F is disposed above the movable material 50, spaced apart from the movable material 50 in the longitudinal direction of the rail 4 (upward in this case), forming a gap between the movable material 50 and the restricting portion 4F. When the movable material 50 moves in a direction away from the receiving portion 4E (upward in this case) within the recess 4G, the movable material 50 moves from the receiving portion 4E toward the restricting portion 4F and abuts against the restricting portion 4F. The restricting portion 4F abuts against the movable material 50 moving in a direction away from the receiving portion 4E, thereby restricting the movement of the movable material 50 in a direction away from the receiving portion 4E. The restricting portion 4F stops the movement of the movable material 50, preventing the movable material 50 from disengaging from the locking portion 4C (recess 4G).

[0062] The guide portions 4H and 4I are inclined surfaces that slope toward the indoor side (the side of the stopping device 6) with respect to the longitudinal direction of the rail 4, and are located outside the recessed portion 4G of the rail 4 in the longitudinal direction of the rail 4. When the movable material 50 moves from the outside of the locking portion 4C toward the recessed portion 4G, the guide portions 4H and 4I guide the movable material 50 toward the recessed portion 4G of the rail 4. The first guide portion 4H is located below the recessed portion 4G and the receiving portion 4E and connects to the receiving portion 4E. When the movable material 50 moves toward the receiving portion 4E while contacting the first guide portion 4H, the movable material 50 is pushed toward the separated position P2 by the first guide portion 4H and moves from the locking position P1 toward the separated position P2. When the movable material 50 moves beyond the first guide portion 4H to the receiving portion 4E (recessed portion 4G), the biasing force of the biasing means 7 causes the movable material 50 to move to the locking position P1 and be positioned within the recessed portion 4G.

[0063] The second guide portion 4I is located above the recessed portion 4G and the restricting portion 4F and is connected to the restricting portion 4F. When the movable material 50 moves toward the restricting portion 4F while contacting the second guide portion 4I, the movable material 50 is pushed toward the separated position P2 by the second guide portion 4I and moves from the locking position P1 toward the separated position P2. When the movable material 50 moves beyond the second guide portion 4I to the restricting portion 4F (recessed portion 4G), the biasing force of the biasing means 7 causes the movable material 50 to move to the locking position P1 and be positioned within the recessed portion 4G. After being guided to the recessed portion 4G by the guide portions 4H and 4I, the movable material 50 is received and locked by the receiving portion 4E.

[0064] In the fitting 1 of the second embodiment, the movable material 50 is locked by the receiving portions 4E of the locking portions 4C at each position of the multiple locking portions 4C in the longitudinal direction of the rail 4 (the movement direction of the screen device 5), and is held by the receiving portions 4E of the locking portions 4C at the locking position P1. The receiving portions 4E of the locking portions 4C stably lock the movable material 50, making it possible to reliably hold the screen device 5 in the stopped position. In addition, the restricting portions 4F of the locking portions 4C prevent the movable material 50 from coming off the locking portions 4C, making it possible to maintain the movable material 50 in a state locked by the locking portions 4C.
