Description

Technical Field

[0001] The present invention relates to a fitting having a shoji that slides in the opening and closing direction.

Background Art

[0002] In a sliding window, which is a fitting, a crescent, which is a locking device, is provided on a calling frame, which is a vertical frame of a pair of shojis. In the state where the shoji is closed, the shoji is locked by the crescent. Further, the crescent lock of the crescent is provided on the inner calling frame of the inner shoji, and the crescent receiver of the crescent is provided on the outer calling frame of the outer shoji. However, depending on the temperature difference between the inside and outside of the shoji, the calling frame may be deformed so as to warp in the inside-outside direction of the room, and the crescent receiver may come into contact with the calling frame of the inner shoji. As a result, the sliding of the shoji may be hindered, which may interfere with the opening and closing of the shoji, and the shoji may not be locked by the crescent. In particular, in the case of a shoji with high heat insulation performance, the temperature difference between the inside and outside of the shoji becomes large, so that the deformation of the calling frame in the inside-outside direction of the room becomes large, and the crescent receiver is likely to come into contact with the calling frame of the inner shoji. On the other hand, conventionally, a composite sash in which a collision avoidance member is attached to the inner calling frame is known (see Patent Document 1).

[0003] In the conventional composite sash described in Patent Document 1, when closing the shoji, the tip of the ridge of the collision avoidance member contacts the indoor side surface of the outer calling frame to maintain the distance between the outer calling frame and the inner calling frame, and prevent the tight material of the inner calling frame from colliding with the outer calling frame and being damaged. However, in the conventional composite sash, in order to prevent the tight material from colliding with the outer calling frame, it is necessary to limit by the collision avoidance member so that the minimum distance between the indoor side surface of the outer calling frame and the outdoor side surface of the inner calling frame does not become smaller than the protruding length of the tight material. Therefore, the protruding length of the ridge of the collision avoidance member is the same length as the protruding length of the tight material, or longer than the protruding length of the tight material. Along with this, when the tip of the ridge of the collision avoidance member contacts the indoor side surface of the outer calling frame, there is a possibility that the tight material does not contact the indoor side surface of the outer calling frame, and the airtightness between the outer calling frame and the inner calling frame of the shoji is not exhibited.

Embodiments for Carrying Out the Invention

[0009] An embodiment of the fitting of the present invention will be described with reference to the drawings. The fitting of the present embodiment is a fitting including at least one shoji that slides in the opening and closing direction, and is installed in an opening of a building. Further, the fitting is installed between the indoor (interior) and outdoor (exterior) of the building, and closes the opening of the building by the shoji. Hereinafter, taking the case where the fitting is a sliding window as an example, the fitting of the present embodiment will be described.

[0010] FIG. 1 is a front view showing the fitting 1 of the present embodiment, showing the fitting 1 installed in a building as viewed from the indoor side. FIG. 2 is a longitudinal sectional view showing the fitting 1 of the present embodiment, and FIG. 3 is a transverse sectional view showing the fitting 1 of the present embodiment. As shown in the figure, the fitting 1 includes two openable and closable shoji screens 2 and 3 (first shoji screen 2, second shoji screen 3) that are sliding shoji screens, a locking device 4 attached to the shoji screens 2 and 3, and a frame body 5 surrounding the shoji screens 2 and 3. The opening 5A of the frame body 5 is opened and closed by the shoji screens 2 and 3.

[0011] When the fitting 1 installed in the building is viewed from the front (see FIG. 1), the vertical direction is the vertical direction R, and the horizontal direction is the horizontal direction S. In FIG. 1, the vertical direction R is the vertical direction, and the horizontal direction S is the horizontal direction. The indoor-outdoor direction T (see FIGS. 2 and 3) is the indoor-outdoor direction (indoor-outdoor direction) of the fitting 1 installed in the building. Further, the indoor-outdoor direction T is the front-rear direction (depth direction) and the thickness direction of the shoji screens 2 and 3 when the fitting 1 installed in the building is viewed from the front, and in FIG. 3, it is the horizontal direction orthogonal to the horizontal direction S. Thus, the directions related to the fitting 1 are specified in the state of being installed in the building. Also, the indoor side and the outdoor side with respect to the fitting 1 are the indoor side and the outdoor side in the state of being installed in the building.

[0012] The frame body 5 is a rectangular opening frame (window frame) and is installed in the opening of the building. Further, the frame body 5 has four frames 10 to 13 (upper frame 10, lower frame 11, a pair of vertical frames 12, 13) combined with each other, and a rectangular opening 5A is formed by the four frames 10 to 13. The frames 10 to 13 are frame members constituting the frame body 5 and are made of, for example, profile materials (extruded profile materials) formed by extrusion molding. The upper frame 10 and the lower frame 11 are the upper and lower horizontal frames of the frame body 5 and extend in the horizontal direction (horizontal direction S) at the upper and lower parts of the frame body 5. The pair of vertical frames 12, 13 (first vertical frame 12, second vertical frame 13) are side frames located on the left and right side parts of the frame body 5 and extend in the vertical direction (vertical direction R) at the side parts of the frame body 5. The ends of the upper frame 10, the lower frame 11, and the left and right vertical frames 12, 13 are connected to each other, and the frames 10 to 13 are framed.

[0013] The upper frame 10 and the lower frame 11 (see Fig. 2) each have two rails 10A, 10B, 11A, 11B (the first rails 10A, 11A, the second rails 10B, 11B) that protrude toward the inside of the opening 5A of the frame body 5. In each of the upper frame 10 and the lower frame 11, the rails 10A, 10B, 11A, 11B are formed in parallel with each other and extend in the longitudinal direction (left - right direction S) of the frames 10, 11. The first rails 10A, 11A are indoor - side rails located on the indoor side, and the second rails 10B, 11B are outdoor - side rails located on the outdoor side.

[0014] The shoji 2, 3 are slide - type movable shoji (panel bodies) that move by sliding and are movably (slidably) arranged in the opening 5A of the frame body 5. The shoji 2, 3 slide in the left - right direction S in the opening 5A of the frame body 5 and move in a drawn - apart state. By the sliding of each of the shoji 2, 3, the opening 5A of the frame body 5 is opened and closed. When the pair of shoji 2, 3 are in the closed state, the pair of shoji 2, 3 are locked by the locking device 4. In a state where the locking by the locking device 4 is released, the shoji 2, 3 slide in a drawn - apart manner in the opening - closing directions (opening directions K1, K2, closing directions H1, H2) to open and close.

[0015] The opening - closing directions of the shoji 2, 3 are the sliding directions (here, the left - right direction S) of the shoji 2, 3 when opening and closing the shoji 2, 3. The opening directions K1, K2 of the shoji 2, 3 are the directions in which the shoji 2, 3 slide when opening the shoji 2, 3, and the closing directions H1, H2 of the shoji 2, 3 are the directions in which the shoji 2, 3 slide when closing the shoji 2, 3. Therefore, the opening directions K1, K2 and the closing directions H1, H2 are respectively one side and the other side of the sliding direction (opening - closing direction) of the shoji 2, 3. Also, the opening direction K1 of the first shoji 2 and the opening direction K2 of the second shoji 3 are in opposite directions, and the closing direction H1 of the first shoji 2 and the closing direction H2 of the second shoji 3 are in opposite directions.

[0016] The first shoji 2 is a first-side shoji located on one side in the indoor-outdoor direction T, and the second shoji 3 is a second-side shoji located on the other side in the indoor-outdoor direction T. Here, one side in the indoor-outdoor direction T is the indoor side, and the other side in the indoor-outdoor direction T is the outdoor side. Therefore, the first shoji 2 is an indoor-side shoji (inner shoji) located on the indoor side, and the second shoji 3 is an outdoor-side shoji (outer shoji) located on the outdoor side. The first shoji 2 is slidably connected to the first rails 10A and 11A and slides along the first rails 10A and 11A. The second shoji 3 is slidably connected to the second rails 10B and 11B and slides along the second rails 10B and 11B.

[0017] The first shoji 2 is on the indoor side of the second shoji 3 and slides in the opening direction K1 and the closing direction H1 to open and close, and is arranged at the fully closed position F1 by sliding in the closing direction H1. The second shoji 3 is on the outdoor side of the first shoji 2 and slides in the opening direction K2 and the closing direction H2 to open and close, and is arranged at the fully closed position F2 by sliding in the closing direction H2.

[0018] The fully closed positions F1 and F2 of the shojis 2 and 3 are the positions where the shojis 2 and 3 are respectively arranged when the shojis 2 and 3 are completely closed. The shojis 2 and 3 slide from the open state in the closing directions H1 and H2 respectively and are arranged at the fully closed positions F1 and F2. When the pair of shojis 2 and 3 are respectively arranged at their fully closed positions F1 and F2, the opening 5A of the frame body 5 is closed by the pair of shojis 2 and 3. Also, the shojis 2 and 3 slide from the fully closed positions F1 and F2 in the opening directions K1 and K2 respectively to become open and are arranged at the fully open position.

[0019] Each of the shoji screens 2 and 3 has a rectangular frame 20, 30 and panels 21, 31 disposed inside the frames 20, 30. The panels 21, 31 are made of glass (e.g., double glazing, laminated glass) and are respectively fitted into the frames 20, 30. The frame 20 of the first shoji screen 2 has four frames 22 to 25 (upper frame 22, lower frame 23, door end frame 24, summons frame 25) combined with each other, and the frame 30 of the second shoji screen 3 has four frames 32 to 35 (upper frame 32, lower frame 33, door end frame 34, summons frame 35) combined with each other. The frames 22 to 25, 32 to 35 are frame members constituting the frames 20, 30 and are made of, for example, shaped materials (extruded shaped materials) formed by extrusion molding.

[0020] The upper frames 22, 32 and the lower frames 23, 33 are the upper and lower horizontal frames of the frames 20, 30 and extend horizontally at the upper and lower parts of the frames 20, 30. The door end frames 24, 34 and the summons frames 25, 35 are the left and right vertical frames of the frames 20, 30 respectively and extend vertically at the left and right side parts of the frames 20, 30. The respective ends of the frames 22 to 25 and the frames 32 to 35 are connected to each other, and the frames 22 to 25 and the frames 32 to 35 are respectively framed.

[0021] The door end frames 24, 34 and the summons frames 25, 35 are the ends (edges) of the shoji screens 2, 3 in the opening and closing direction. The door end frames 24, 34 are located at the front ends on the closing directions H1, H2 of the shoji screens 2, 3, and the summons frames 25, 35 are located at the front ends on the opening directions K1, K2 of the shoji screens 2, 3. The summons frame 25 of the first shoji screen 2 is an indoor summons frame (inner summons frame) located on the indoor side, and the summons frame 35 of the second shoji screen 3 is an outdoor summons frame (outer summons frame) located on the outdoor side. When the pair of shoji screens 2, 3 are arranged in the fully closed positions F1, F2, the summons frames 25, 35 of the pair of shoji screens 2, 3 overlap in the indoor-outdoor direction T and face each other and summon each other.

[0022] The locking device 4 is crescent-shaped and has a crescent lock 4A provided on the first sliding door 2 and a crescent receiver 4B provided on the second sliding door 3 for receiving the crescent lock 4A. The crescent lock 4A is a locking component of the locking device 4 provided on the calling frame 25 of the first sliding door 2, and the crescent receiver 4B is a lock receiving component of the locking device 4 provided on the calling frame 35 of the second sliding door 3. When the crescent lock 4A is received and engaged by the crescent receiver 4B, the pair of sliding doors 2 and 3 are locked.

[0023] The calling frames 25 and 35 of the sliding doors 2 and 3 are vertical frames located on one side (the front side of the opening directions K1 and K2) in the opening and closing direction of the sliding doors 2 and 3. Among the calling frames 25 and 35 of the pair of sliding doors 2 and 3, the calling frames 25 and 35 of one of the sliding doors 2 and 3 are vertical members facing the calling frames 25 and 35 of the other sliding door 2 and 3. Thus, the fitting 1 includes the vertical frames of the sliding doors and vertical members facing the vertical frames of the sliding doors in a state where the sliding doors are arranged in the fully closed position. The vertical frames of the sliding doors are arranged on the indoor side or the outdoor side of the vertical members and are arranged facing the vertical members in the indoor-outdoor direction T. The vertical members are vertical portions extending in the vertical direction and are arranged along the vertical frames of the sliding doors. Also, one of the vertical frames of the sliding doors and the vertical members has a first facing portion facing the other of the vertical frames of the sliding doors and the vertical members, and the other of the vertical frames of the sliding doors and the vertical members has a second facing portion facing the one of the vertical frames of the sliding doors and the vertical members.

[0024] The vertical frames of the sliding doors and the vertical members are the calling frames 25 and 35 of the sliding doors 2 and 3 (see FIG. 3). Here, the calling frame 25 of the first sliding door 2 is the vertical frame 6, and the calling frame 35 of the second sliding door 3 is the vertical member 7. Also, the calling frame 25 (vertical frame 6) of the first sliding door 2 has a first facing portion 40, and the calling frame 35 (vertical member 7) of the second sliding door 3 has a second facing portion 50. In a state where the sliding doors 2 and 3 are arranged in the fully closed positions F1 and F2, the calling frame 25 of the first sliding door 2 is arranged on the indoor side of the calling frame 35 of the second sliding door 3, and the calling frames 25 and 35 of the sliding doors 2 and 3 are arranged facing each other in the indoor-outdoor direction T. The calling frame 35 of the second sliding door 3 is a proximity portion close to the calling frame 25 of the first sliding door 2, and when the sliding doors 2 and 3 are arranged in the fully closed positions F1 and F2, it is arranged close to the calling frame 25 of the first sliding door 2 in the indoor-outdoor direction T and is mated with the calling frame 25 of the first sliding door 2.

[0025] The first facing portion 40 is a one-sided facing portion provided on one of the mating frames 25 and 35 of the shoji screens 2 and 3, and the second facing portion 50 is the other-sided facing portion provided on the other of the mating frames 25 and 35 of the shoji screens 2 and 3. One of the mating frames 25 and 35 of the shoji screens 2 and 3 that is located on the indoor side (here, the mating frame 25 of the first shoji screen 2 which is the vertical frame 6) has the first facing portion 40, and the other of the mating frames 25 and 35 of the shoji screens 2 and 3 that is located on the outdoor side (here, the mating frame 35 of the second shoji screen 3 which is the vertical member 7) has the second facing portion 50.

[0026] The first facing portion 40 is the outdoor-side portion of the mating frame 25 of the first shoji screen 2 (the portion facing the mating frame 35 of the second shoji screen 3 and the second facing portion 50), and is arranged facing the outdoor side and the second facing portion 50. The second facing portion 50 is the indoor-side portion of the mating frame 35 of the second shoji screen 3 (the portion facing the mating frame 25 of the first shoji screen 2 and the first facing portion 40), and is arranged facing the indoor side and the first facing portion 40. In a state where the shoji screens 2 and 3 are arranged at the fully closed positions F1 and F2, the first facing portion 40 and the second facing portion 50 are arranged facing each other across a location between the mating frame 25 of the first shoji screen 2 and the mating frame 35 of the second shoji screen 3 in the indoor-outdoor direction T.

[0027] FIG. 4 is a cross-sectional view showing the mating frames 25 and 35 of the shoji screens 2 and 3 arranged at the fully closed positions F1 and F2 of the present embodiment, and shows the mating frames 25 and 35 of the shoji screens 2 and 3 cut along the line X1-X1 in FIG. 1. FIG. 5 is a cross-sectional view showing the mating frames 25 and 35 of the shoji screens 2 and 3 sliding toward the fully closed positions F1 and F2 of the present embodiment, and shows a cross-sectional view of the same location as the mating frames 25 and 35 of the shoji screens 2 and 3 shown in FIG. 4. FIG. 6 is a view showing the mating frame 35 of the second shoji screen 3 as viewed in the direction of arrow Y1 in FIG. 5 and the mating frame 25 of the first shoji screen 2 as viewed in the direction of arrow Y2 in FIG. 5, and the mating frame 25 of the first shoji screen 2 is shown by a dashed line. FIG. 7 is a cross-sectional view showing the mating frames 25 and 35 of the shoji screens 2 and 3 sliding toward the fully closed positions F1 and F2 of the present embodiment, and shows an intermediate stage in which the shoji screens 2 and 3 shown in FIG. 5 slide toward the fully closed positions F1 and F2. In FIGS. 5 to 7, the description of the crescent lock 4A is omitted.

[0028] FIG. 8 is a cross-sectional view showing the mating frames 25 and 35 of the shoji screens 2 and 3 arranged at the fully closed positions F1 and F2 of the present embodiment, and shows the mating frames 25 and 35 of the shoji screens 2 and 3 cut along the line X2-X2 in FIG. 1. FIG. 9 is a cross-sectional view showing the mating frames 25 and 35 of the shoji screens 2 and 3 sliding toward the fully closed positions F1 and F2 of the present embodiment, and shows a cross-sectional view of the same location as the mating frames 25 and 35 of the shoji screens 2 and 3 shown in FIG. 8.

[0029] As shown in the drawing, the mating frame 25 (vertical frame 6) and the first opposing portion 40 of the first shoji screen 2 are located on the indoor side of the mating frame 35 (vertical member 7) and the second opposing portion 50 of the second shoji screen 3, and the mating frame 35 and the second opposing portion 50 of the second shoji screen 3 are located on the outdoor side of the mating frame 25 and the first opposing portion 40 of the first shoji screen 2. The mating frame 25 of the first shoji screen 2 has a guide component 60 (see FIGS. 4 to 7) for guiding the sliding of the shoji screens 2 and 3 and a first tight material 26 (see FIGS. 6, 8, and 9) that can be elastically deformed. The mating frame 35 of the second shoji screen 3 has a second tight material 36 that can be elastically deformed.

[0030] The guide component 60 is attached to the first opposing part 40, is located between the first opposing part 40 and the second opposing part 50 in the indoor-outdoor direction T, and faces the second opposing part 50. The first tight material 26 is one-sided tight material provided on one of the mating frames 25 and 35 of the sliding doors 2 and 3, and the second tight material 36 is the other-sided tight material provided on the other of the mating frames 25 and 35 of the sliding doors 2 and 3. The guide component 60 is attached to the first opposing part 40 located on the indoor side of the two opposing parts 40 and 50, and the first tight material 26 is provided. Also, the second tight material 36 is provided on the second opposing part 50 located on the outdoor side of the two opposing parts 40 and 50.

[0031] The tight materials 26 and 36 extend in the longitudinal direction (vertical direction R) of the mating frames 25 and 35, and are arranged to be spaced apart from each other in the opening and closing direction (left-right direction S) of the sliding doors 2 and 3. The first tight material 26 is located on the front side in the opening direction K1 of the first sliding door 2 with respect to the second tight material 36, and the second tight material 36 is located on the front side in the opening direction K2 of the second sliding door 3 with respect to the first tight material 26. The first tight material 26 is notched at the location of the guide component 60 and is vertically divided at the location of the guide component 60 (see FIG. 6). Therefore, the first tight material 26 is located on both sides in the vertical direction R of the guide component 60 and is provided on the portion excluding the location of the guide component 60 in the longitudinal direction of the mating frame 25. The second tight material 36 is provided over the entire longitudinal direction of the mating frame 35.

[0032] In a state where the sliding doors 2 and 3 are arranged at the fully closed positions F1 and F2, the first tight material 26 (see FIG. 8) protrudes in the indoor-outdoor direction T (here, the outdoor side) from the first opposing part 40 toward the second opposing part 50, abuts against the second opposing part 50, and closes the portion between the first opposing part 40 and the second opposing part 50. The first tight material 26 (see FIGS. 4 and 6) is not provided at the location of the guide component 60 and does not abut against the second opposing part 50 at the location of the guide component 60. The second tight material 36 (see FIGS. 4 and 8) protrudes in the indoor-outdoor direction T (here, the indoor side) from the second opposing part 50 toward the first opposing part 40, abuts against the first opposing part 40 and the guide component 60, and closes the portion between the first opposing part 40 and the second opposing part 50.

[0033] The crescent lock 4A and the crescent receiver 4B are provided on the mating frames 25 and 35 of the sliding doors 2 and 3, and are arranged to face each other in the indoor-outdoor direction T (see Fig. 4). Therefore, the crescent lock 4A and the crescent receiver 4B constitute a part of the mating frames 25 and 35 facing each other, and also constitute a part of the facing portions 40 and 50 of the mating frames 25 and 35 facing each other. Thus, the mating frame 25 and the first facing portion 40 of the first sliding door 2 have the crescent lock 4A, and the mating frame 35 and the second facing portion 50 of the second sliding door 3 have the crescent receiver 4B.

[0034] The first facing portion 40 is a finding portion on the outdoor side of the mating frame 25 of the first sliding door 2 and includes the crescent lock 4A. The second facing portion 50 is a finding portion on the indoor side of the mating frame 35 of the second sliding door 3 and includes the crescent receiver 4B. The first facing portion 40 has an attachment surface 41 (see Fig. 4) to which the guide component 60 is attached, left and right protrusions 42 (see Figs. 6 and 8), and a holding groove portion 43 (see Figs. 6 and 8) for holding the guide component 60. The attachment surface 41 is located on the indoor side of the guide component 60, and the attachment surface 41 and the guide component 60 are adjacent to the crescent lock 4A in the opening and closing direction of the first sliding door 2. The first tight material 26 is connected to one of the left and right protrusions 42 and protrudes from the protrusion 42 toward the second facing portion 50.

[0035] The left and right protrusions 42 of the first opposing portion 40 are formed at intervals in the opening and closing direction of the first shoji 2, extend in the longitudinal direction of the calling frame 25 of the first shoji 2, and face each other in the opening and closing direction of the first shoji 2. Further, the left and right protrusions 42 protrude in the indoor-outdoor direction T (here, the outdoor side) toward the second opposing portion 50, and bend toward each other at the ends on the second opposing portion 50 side (outdoor side). The protrusion 42 is notched at the locations of the guide component 60 and the mounting surface 41, is divided vertically at the locations of the guide component 60 and the mounting surface 41, and is located on both sides in the vertical direction R of the guide component 60 and the mounting surface 41. The holding groove portion 43 is a groove-shaped portion formed between the protrusion 42 and the mounting surface 41, and is formed at two locations on the left and right of the first opposing portion 40 at intervals in the opening and closing direction of the first shoji 2. The left and right holding groove portions 43 are respectively located on both sides in the vertical direction R of the guide component 60 and the mounting surface 41, and face each other in the opening and closing direction of the first shoji 2.

[0036] The guide component 60 has a locking portion 61 that is locked to the holding groove portion 43 of the first opposing portion 40 (see FIG. 6). The locking portion 61 is a protruding piece formed at the upper and lower ends of the guide component 60, and is formed at two locations on the left and right of the guide component 60 at intervals in the opening and closing direction of the first shoji 2 at the upper and lower ends of the guide component 60 respectively. The left and right locking portions 61 are respectively located at the upper and lower ends of the guide component 60, and are respectively locked to the holding groove portion 43. The locking portion 61 is a fitting portion that protrudes in the vertical direction R, is fitted inside the holding groove portion 43, is locked to the holding groove portion 43, and is held by the holding groove portion 43.

[0037] The upper and lower locking portions 61 of the guide component 60 are locked to the upper and lower holding groove portions 43, and the guide component 60 is sandwiched between the upper and lower holding groove portions 43. The holding groove portion 43 restricts the movement of the locking portion 61 and the guide component 60 in the indoor-outdoor direction T and the left-right direction S. Further, by sandwiching the guide component 60 between the upper and lower holding groove portions 43, the movement of the guide component 60 in the vertical direction R is restricted. Thereby, the guide component 60 abuts against the mounting surface 41 and the first opposing portion 40, and is attached to the mounting surface 41 and the first opposing portion 40.

[0038] In a state where the shoji screens 2 and 3 are arranged at the fully closed positions F1 and F2, the guide component 60 is arranged at a position (indoors position) separated from the second facing portion 50 in the indoor-outdoor direction T, compared to the first tight material 26 (the end portion (tip portion) on the second facing portion 50 side (outdoor side) of the first tight material 26). Therefore, the first tight material 26 is arranged at a position (outdoor side position) closer to the second facing portion 50 than the guide component 60 in the indoor-outdoor direction T. Thus, when comparing the positions in the indoor-outdoor direction T, the portion of the guide component 60 that is located closest to the second facing portion 50 is arranged at a position separated from the second facing portion 50 compared to the portion (tip portion) of the first tight material 26 that is located closest to the second facing portion 50.

[0039] The guide component 60 is not arranged at a position closer to the second facing portion 50 than the first tight material 26, and is arranged only at a position separated from the second facing portion 50 compared to the first tight material 26. Therefore, the first tight material 26 can abut against the second facing portion 50 in a state where the second facing portion 50 is in contact with the guide component 60, and can also abut against the second facing portion 50 even in a state where the second facing portion 50 is not in contact with the guide component 60. Thus, the first tight material 26 surely abuts against the second facing portion 50.

[0040] When the mating frames 25 and 35 of the shoji screens 2 and 3 are deformed so as to warp in the indoor-outdoor direction T due to the temperature difference between the indoor side and the outdoor side of the shoji screens 2 and 3 (the indoor-outdoor temperature difference), the facing portions 40 and 50 of the mating frames 25 and 35 of the shoji screens 2 and 3 may come into contact with each other, preventing the shoji screens 2 and 3 from sliding. In contrast, the guide component 60 has a sliding surface portion 62 (see FIGS. 4 to 7) for sliding the second facing portion 50, and guides and slides the shoji screens 2 and 3 by means of the sliding surface portion 62. When the sliding surface portion 62 comes into contact with the second facing portion 50 as the shoji screens 2 and 3 slide, the sliding surface portion 62 slides the second facing portion 50 while separating the first facing portion 40 and the second facing portion 50 from each other in the indoor-outdoor direction T, guiding the sliding shoji screens 2 and 3.

[0041] The sliding surface portion 62 of the guide component 60 is a surface portion that faces the second opposing portion 50 in the guide component 60, and is arranged facing the outdoor side and the second opposing portion 50. The second opposing portion 50 slides along the sliding surface portion 62, and the guide component 60 enters between the first opposing portion 40 and the second opposing portion 50. At this time, the guide component 60 applies a force in a direction separating the first opposing portion 40 and the second opposing portion 50 from each other in the indoor-outdoor direction T to relatively displace the first opposing portion 40 and the second opposing portion 50 in a direction separating them from each other in the indoor-outdoor direction T. Along with this, the guide component 60 widens the indoor-outdoor direction T interval between the first opposing portion 40 and the second opposing portion 50, and relatively separates the first opposing portion 40 and the second opposing portion 50 from a state of contacting each other to a state of not contacting each other in the indoor-outdoor direction T.

[0042] By separating the opposing portions 40 and 50 from each other, the guide component 60 separates the calling frames 25 and 35 of the shoji 2 and 3 in the indoor-outdoor direction T, and widens the indoor-outdoor direction T interval between the calling frames 25 and 35. In that state, the guide component 60 guides and slides the shoji 2 and 3 by the sliding surface portion 62 without bringing the first opposing portion 40 and the second opposing portion 50 into contact. The shoji 2 and 3 slide while being guided by the guide component 60 with the guide component 60 sandwiched between the opposing portions 40 and 50 of each other.

[0043] The second opposing portion 50 slides relative to the sliding surface portion 62 of the guide component 60 in the opening and closing direction of the shoji 2 and 3. The guide component 60 maintains the indoor-outdoor direction T interval between the first opposing portion 40 and the second opposing portion 50 at an interval where the shoji 2 and 3 can slide (an interval where the first opposing portion 40 and the second opposing portion 50 do not contact) by the sliding surface portion 62, and guides the shoji 2 and 3 in the sliding direction. The first opposing portion 40 and the second opposing portion 50 are separated from each other in the indoor-outdoor direction T more than in the state before the second opposing portion 50 contacts the sliding surface portion 62 when the second opposing portion 50 contacts the sliding surface portion 62. The indoor-outdoor direction T interval between the first opposing portion 40 and the second opposing portion 50 after the second opposing portion 50 contacts the sliding surface portion 62 is wider than the indoor-outdoor direction T interval between the first opposing portion 40 and the second opposing portion 50 before the second opposing portion 50 contacts the sliding surface portion 62. In that state, the sliding of the shoji 2 and 3 is guided by the sliding surface portion 62, and the shoji 2 and 3 slide.

[0044] Here, as the shoji 2 and 3 slide, the crescent receiver 4B of the second opposing portion 50 contacts the sliding surface portion 62 of the guide component 60 and slides on the sliding surface portion 62. For example, the sliding surface portion 62 contacts two edge portions 4C, 4D (first edge portion 4C, second edge portion 4D) provided on the crescent receiver 4B. The two edge portions 4C, 4D are spaced apart in the opening and closing direction of the second shoji 3 and are arranged facing away from each other in the opposite direction to the opening and closing direction of the second shoji 3. The first edge portion 4C is located on the front side in the closing direction H2 of the second shoji 3 with respect to the second edge portion 4D and is arranged facing the front side in the closing direction H2 of the second shoji 3. The second edge portion 4D is located on the front side in the opening direction K2 of the second shoji 3 with respect to the first edge portion 4C and is arranged facing the front side in the opening direction K2 of the second shoji 3. When the shoji 2 and 3 slide in the closing directions H1, H2 toward the fully closed positions F1, F2, the first edge portion 4C of the crescent receiver 4B contacts the sliding surface portion 62 and slides on the sliding surface portion 62. When each of the shoji 2 and 3 slides in the opening directions K1, K2 from the fully closed positions F1, F2, the second edge portion 4D of the crescent receiver 4B contacts the sliding surface portion 62 and slides on the sliding surface portion 62.

[0045] The sliding surface portion 62 of the guide component 60 has a flat surface portion 63 provided on the central side portion including the center of the sliding surface portion 62 in the opening and closing direction of the first shoji 2, and inclined portions 64, 65 provided on the end portion including the tip of the sliding surface portion 62 in the opening and closing direction of the first shoji 2. The flat surface portion 63 is formed in a flat shape, arranged along the opening and closing direction of the first shoji 2, and faces the second opposing portion 50 in the indoor-outdoor direction T. The end portion of the sliding surface portion 62 is the tip side portion including the tip of the sliding surface portion 62 and is located in the portion including the tips on both sides of the sliding surface portion 62 in the opening and closing direction of the first shoji 2. The inclined portions 64, 65 are provided at least at one (either one or both) of the end portions on both sides of the sliding surface portion 62 and are formed in an inclined shape. Further, the inclined portions 64, 65 are inclined in a direction gradually separating from the second opposing portion 50 toward the tip of the sliding surface portion 62 with respect to the opening and closing direction of the first shoji 2. The inclined portions 64, 65 are formed in a curved shape or a flat shape and curve or extend straight in the inclined direction with respect to the opening and closing direction of the first shoji 2.

[0046] Here, the inclined portions 64 and 65 of the sliding surface portion 62 are provided at both end portions of the sliding surface portion 62. One of the inclined portions (the first inclined portion 64) of the inclined portions 64 and 65 on both sides is provided at one end portion of the sliding surface portion 62 located on the front side in the closing direction H1 of the first shoji 2, and is formed in a curved shape. Further, the other inclined portion (the second inclined portion 65) of the inclined portions 64 and 65 on both sides is provided at the other end portion of the sliding surface portion 62 located on the front side in the opening direction K1 of the first shoji 2, and is formed in a planar shape. The first inclined portion 64 comes into contact with the second opposing portion 50 when the shojis 2 and 3 slide in the closing directions H1 and H2 toward the fully closed positions F1 and F2. The second inclined portion 65 comes into contact with the second opposing portion 50 when the shojis 2 and 3 slide in the opening directions K1 and K2 from the fully closed positions F1 and F2.

[0047] The flat portion 63 of the sliding surface portion 62 is provided between both end portions (the inclined portions 64 and 65) of the sliding surface portion 62. The inclined portions 64 and 65 are continuously formed with the flat portion 63, and are inclined so as to gradually separate from the second opposing portion 50 toward the tip from the flat portion 63 of the sliding surface portion 62 with respect to the opening and closing direction of the first shoji 2, and are inclined toward the indoor side.

[0048] As the shojis 2 and 3 slide, when the second opposing portion 50 comes into contact with the inclined portions 64 and 65 of the sliding surface portion 62, the second opposing portion 50 slides from the tip 64A, 65A sides toward the flat portion 63 side of the inclined portions 64 and 65. The sliding surface portion 62 slides the shojis 2 and 3 while gradually separating the first opposing portion 40 and the second opposing portion 50 in the indoor-outdoor direction T by the inclined portions 64 and 65 that slide the second opposing portion 50. The second opposing portion 50 slides from the inclined portions 64 and 65 to the flat portion 63 of the sliding surface portion 62, gets on the second opposing portion 50 side (outdoor side) of the sliding surface portion 62 without coming into contact with the first opposing portion 40, and slides on the flat portion 63. The sliding surface portion 62 slides the shojis 2 and 3 while maintaining the interval in the indoor-outdoor direction T between the first opposing portion 40 and the second opposing portion 50 by the flat portion 63 that slides the second opposing portion 50.

[0049] When comparing the positions in the indoor-outdoor direction T with the shoji 2 and 3 arranged at the fully closed positions F1 and F2, the tip 64A of the first inclined portion 64 is arranged at a position separated from the second opposing portion 50 more than the mounting surface 41 of the first opposing portion 40, and the mounting surface 41 is arranged at a position closer to the second opposing portion 50 than the tip 64A of the first inclined portion 64. The tip 64A of the first inclined portion 64 is the tip of the first inclined portion 64 in the opening and closing direction of the first shoji 2, is located at the tip of the sliding surface portion 62 in the opening and closing direction of the first shoji 2, and is provided at the position most separated from the second opposing portion 50 in the first inclined portion 64, the sliding surface portion 62, and the guide component 60. In the indoor-outdoor direction T, the tip 64A of the first inclined portion 64 is arranged at a position on the indoor side than the mounting surface 41, and the mounting surface 41 is arranged at a position on the outdoor side than the tip 64A of the first inclined portion 64. On the other hand, the tip 65A of the second inclined portion 65 is arranged at the same position as the mounting surface 41 in the indoor-outdoor direction T.

[0050] When comparing the positions in the indoor-outdoor direction T, the portion of the sliding surface portion 62 of the guide component 60 excluding the inclined portions 64 and 65 is arranged at a position separated from the second opposing portion 50 more than the portion of the first tight material 26 (see FIG. 8) located on the second opposing portion 50 side most among the portion of the first opposing portion 40 located on the second opposing portion 50 side most. Here, the second opposing portion 50 side is the outdoor side, and the position separated from the second opposing portion 50 is the indoor side position (the position on the mounting surface 41 side). Also, the second opposing portion 50 is the portion located on the first opposing portion 40 side (indoor side) most of the second opposing portion 50.

[0051] The portion of the sliding surface portion 62 excluding the inclined portions 64 and 65 is a flat surface portion 63 which is a portion of the sliding surface portion 62 other than the inclined portions 64 and 65. The portion of the first opposing portion 40 that is closest to the second opposing portion 50 is the outdoor-side ends of the left and right protrusions 42 which are the portions of the first opposing portion 40 that are located on the outermost outdoor side. The portion of the first tight material 26 that is closest to the second opposing portion 50 is the outdoor-side end of the first tight material 26 which is the portion of the first tight material 26 that is located on the outermost outdoor side. When comparing the positions in the indoor-outdoor direction T, the flat surface portion 63 is at the same position as the outdoor-side ends of the left and right protrusions 42, or at a position more outdoor than the outdoor-side ends of the left and right protrusions 42, and is arranged at a position more indoor than the outdoor-side end of the first tight material 26.

[0052] The guide component 60 has a protective sheet 66 provided on the sliding surface portion 62. The sliding surface portion 62 is entirely covered and protected by the protective sheet 66. The protective sheet 66 covers the flat surface portion 63 and the inclined portions 64 and 65 of the sliding surface portion 62 and protects the entire sliding surface portion 62. When the second opposing portion 50 slides on the sliding surface portion 62, the protective sheet 66 suppresses damage to the sliding surface portion 62 caused by the sliding of the second opposing portion 50.

[0053] The protective sheet 66 is a low-friction sheet that reduces the frictional force on the second opposing portion 50, and reduces the frictional force acting on the second opposing portion 50 that slides on the sliding surface portion 62 as compared to when the protective sheet 66 is not on the sliding surface portion 62. Due to the protective sheet 66, the frictional force (friction coefficient) between the second opposing portion 50 that slides on the sliding surface portion 62 and the sliding surface portion 62 is smaller than the frictional force (friction coefficient) between the second opposing portion 50 and the sliding surface portion 62 when the protective sheet 66 is not on the sliding surface portion 62. The frictional force (friction coefficient) is the dynamic frictional force (dynamic friction coefficient). The protective sheet 66 is a synthetic resin sheet, and here it is a fluororesin sheet made of fluororesin.

[0054] As described above, in the fitting 1 of the present embodiment, the tight materials 26 and 36 and the guide component 60 ensure the airtightness of the mating frames 25 and 35 (vertical frames 6 and vertical members 7) of the sliding doors 2 and 3 of the fitting 1, and when the mating frames 25 and 35 of the sliding doors 2 and 3 are deformed in the indoor-outdoor direction T, the sliding doors 2 and 3 can be smoothly slid. Further, by sliding the second opposing portion 50 along the inclined portions 64 and 65 of the sliding surface portion 62, the first opposing portion 40 and the second opposing portion 50 are gradually separated in the indoor-outdoor direction T, and the sliding doors 2 and 3 can be smoothly slid.

[0055] The tip 64A of the first inclined portion 64 is disposed at a position separated from the second opposing portion 50 more than the mounting surface 41 of the first opposing portion 40. Therefore, even when the amount of deformation of the mating frames 25 and 35 of the sliding doors 2 and 3 in the indoor-outdoor direction T increases, the second opposing portion 50 can be brought into contact with the first inclined portion 64, and the first opposing portion 40 and the second opposing portion 50 are separated in the indoor-outdoor direction T, and the sliding doors 2 and 3 can be slid.

[0056] When comparing the positions in the indoor-outdoor direction T, the flat surface portion 63 of the sliding surface portion 62 is disposed at a position closer to the indoor side than the outdoor side end of the first tight material 26 between the outdoor side ends of the left and right protrusions 42 and the outdoor side end of the first tight material 26. Thereby, the first tight material 26 can be surely brought into contact with the second opposing portion 50, and the sliding surface portion 62 of the guide component 60 can be stably brought into contact with the second opposing portion 50.

[0057] The damage to the sliding surface portion 62 can be suppressed by the protective sheet 66. Further, by locking the locking portion 61 of the guide component 60 to the holding groove portion 43 of the first opposing portion 40, the guide component 60 can be easily attached to the first opposing portion 40. In the fitting 1 provided with the locking device 4 including the crescent lock 4A and the crescent receiver 4B where the crescent receiver 4B of the first opposing portion 40 slides on the sliding surface portion 62, the airtightness of the mating frames 25 and 35 of the sliding doors 2 and 3 is ensured, and the sliding doors 2 and 3 can be smoothly slid.

[0058] Note that the protective sheet 66 is not limited to a fluororesin sheet. For example, it may be a sheet in which cut pile of fluororesin fibers (fluororesin fibers) is spread on the surface. Also, in the sliding surface portion 62 of the guide component 60, similar to the tip 64A of the first inclined portion 64, the tip 65A of the second inclined portion 65 may be arranged at a position separated from the second opposing portion 50 more than the mounting surface 41 of the first opposing portion 40. Portions other than the edge portions 4C and 4D of the crescent receiver 4B of the second opposing portion 50 or portions other than the crescent receiver 4B may contact and slide on the sliding surface portion 62.

[0059] When the second opposing portion 50 contacts the sliding surface portion 62 when the shoji 2 and 3 slide in the closing directions H1 and H2, and the second opposing portion 50 does not contact the sliding surface portion 62 when the shoji 2 and 3 slide in the opening directions K1 and K2, only the first inclined portion 64 may be provided on the sliding surface portion 62 without providing the second inclined portion 65 on the sliding surface portion 62. On the contrary, when the second opposing portion 50 contacts the sliding surface portion 62 when the shoji 2 and 3 slide in the opening directions K1 and K2, and the second opposing portion 50 does not contact the sliding surface portion 62 when the shoji 2 and 3 slide in the closing directions H1 and H2, only the second inclined portion 65 may be provided on the sliding surface portion 62 without providing the first inclined portion 64 on the sliding surface portion 62. Thus, the inclined portions 64 and 65 may be provided only on either one of the end portions on both sides of the sliding surface portion 62.

[0060] The fitting 1 is not limited to a sliding window and may be other fittings (for example, a single-slide window, a window having three or more shoji) provided with a sliding shoji. When the fitting 1 is a single-slide window, in a state where the shoji is arranged at the fully closed position, the vertical frame 6 of the shoji faces, for example, the vertical stud. Therefore, in this case, the vertical stud is the vertical member 7. Also, the vertical member 7 may have the first opposing portion 40, and the vertical frame 6 of the shoji may have the second opposing portion 50, and the guide component 60 may be attached to the first opposing portion 40 of the vertical member 7. Thus, the first opposing portion 40 and the guide component 60 may be provided on either the vertical frame 6 of the shoji or the vertical member 7. The vertical frame 6 of the shoji may be arranged on the indoor side of the vertical member 7 and face the vertical member 7, or may be arranged on the outdoor side of the vertical member 7 and face the vertical member 7.

[0061] As described above, in the present embodiment, the fittings described in the following (1) to (7) are disclosed.
