Description

[Technical Field]

[0001] The present invention relates to fittings such as double sliding windows, single sliding windows, double-hung windows, and entrance sliding doors that are equipped with shoji screens that slide in the opening and closing directions. [Background technology]

[0002] Patent Document 1 discloses a sealing device for a sliding door joint that attaches a packing material made of synthetic resin to the space between the interior side of the joint frame of the outer door of a sliding door and the smoke deflector, and abuts the raised part of this packing material against the smoke deflector of the joint frame of the inner door, thereby improving the airtightness of the joint. The packing material is formed with a roughly U-shaped cross section, with one end engaging with a hook-shaped engaging portion formed on the joint frame of the outer screen, and the other end engaging with a protrusion formed on the tip of the smoke deflector. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jikko No. 54-9426 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, it is necessary to form a hook-shaped locking portion on the outer door frame to lock one end of the packing material, which raises the issue of high manufacturing costs for the outer door frame. Also, since the other end of the packing material only abuts against the protrusion at the tip of the smoke deflector, if the inner door frame is closed with its abutment toward the interior of the room, the tip of the smoke deflector of the inner door frame abuts against the side of the raised portion of the packing material, causing the packing material to deform and risk coming off the smoke deflector.

[0005] The object of the present invention is to provide a fitting that can reduce the risk of guide parts attached to a joint frame coming off and also reduce the manufacturing costs of the joint frame. [Means for solving the problem]

[0006] The present invention is a fitting in which at least one of a first shoji screen or a second shoji screen slides in an opening / closing direction, the first shoji screen having a first joining frame, the second shoji screen having a second joining frame, the first joining frame having a first side wall portion facing the second joining frame and a first smoke deflector portion formed continuously from the first side wall portion, the second joining frame having a second side wall portion facing the first joining frame and a second smoke deflector portion formed continuously from the second side wall portion, a guide part being disposed between the first side wall portion and the first smoke deflector portion, the guide part being disposed along the first side wall portion. a first extension piece arranged along the first side wall portion, a second extension piece arranged along the first smoke deflector portion, and a connecting piece connecting the first extension piece and the second extension piece, wherein the first extension piece is formed with a first protrusion protruding toward the first side wall portion, and the second extension piece is formed with a second protrusion protruding toward the first smoke deflector portion, and the guide component is attached to the first side wall portion and the first smoke deflector portion by inserting the first protrusion into a first recess formed in the first side wall portion and inserting the second protrusion into a second recess formed in the first smoke deflector portion. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a fixture that can reduce the risk of guide parts attached to a smoke deflector coming off and also reduce the manufacturing costs of the fitting frame. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a vertical cross-sectional view showing a sliding window 1, which is a fixture according to an embodiment of the present invention, and Fig. 2 is a horizontal cross-sectional view showing the sliding window 1. Fig. 3 is a horizontal cross-sectional view showing an enlarged joint portion of the sliding screen of the sliding window 1. The sliding window 1 comprises a window frame 2 fixed to an opening in the exterior wall of a building, and an outer shoji screen 3 and an inner shoji screen 4 which are arranged to slide open and close relative to the window frame 2. In the following explanation, the direction perpendicular to the up-down direction and the projection direction (indoor / outdoor direction) of the sliding window 1, i.e., the opening and closing direction in which the outer shoji screen 3 and inner shoji screen 4 slide, is defined as the left-right direction.

[0010] The window frame 2 is composed of an upper frame 21, a lower frame 22, and left and right vertical frames 23, 24 formed from extruded aluminum profiles. The outer shoji screen 3 is constructed by assembling an upper frame 31 formed from an extruded aluminum profile, a lower frame 32, a vertical frame 33 on the door end side, an outer joint frame 34, and double-pane glass 35. The inner shoji screen 4 is constructed by assembling an upper frame 41 formed from an extruded aluminum profile, a lower frame 42, a vertical frame 43 on the door end side, an inner joint frame 44, and double-pane glass 45. The outer shoji screen 3 and the inner shoji screen 4 are configured in a vertical configuration with upper frames 31, 41 and lower frames 32, 42 arranged between the upper and lower ends of vertical frames 33, 43, outer joint frame 34, and inner joint frame 44.

[0011] The upper frame 21 of the window frame 2 has a projection piece 210, an upper rail 211 that guides the outer shoji screen 3, and an upper guide groove 212 that guides the inner shoji screen 4. The upper rail 211 is formed by extending downward from the projection piece 210. The upper guide groove 212 is composed of a groove that is open downward and is partitioned by the projection piece 210, an interior hanging piece 213, and an intermediate hanging piece 214. The indoor side hanging piece 213 extends downward from the indoor side end of the projection piece portion 210. The intermediate hanging piece 214 is formed in the projection piece portion 210 between the upper rail 211 and the indoor side hanging piece 213. Specifically, the intermediate hanging piece 214 is arranged between the upper frame 31 of the outer shoji screen 3 and the upper frame 41 of the inner shoji screen 4. The lower frame 22 of the window frame 2 has a projection portion 220, a lower rail 221 that guides the outer shoji screen 3, and a lower rail 222 that guides the inner shoji screen 4.

[0012] The window frame 2 is fitted with airtight material that abuts against the interior surfaces of the outer shoji screen 3 and inner shoji screen 4. That is, the intermediate hanging piece 214 and the indoor hanging piece 213 have dovetail grooves that open to the outside of the room, and each dovetail groove is fitted with an airtight material 51 that abuts the indoor surface of the upper frame 31 and an airtight material 52 that abuts the indoor surface of the upper frame 41. An airtight material 53 that abuts the indoor surface of the lower frame 32 and an airtight material 54 that abuts the indoor surface of the lower frame 42 are attached to the dovetail groove formed in the lower frame 22. An airtight material 55 that abuts against the indoor surface of vertical frame 33 is attached to the dovetail groove formed in vertical frame 23. An airtight material 56 that abuts against the indoor surface of vertical frame 43 is attached to the dovetail groove formed in vertical frame 24. As shown in FIG. 2, a dovetail groove is also formed on the exterior surface of the inner joint frame 44, and an airtight material 57 is attached to abut against the interior surface of the outer joint frame 34. These airtight materials 51 to 56 ensure airtightness between the window frame 2 and the outer and inner shoji screens 3 and 4, and airtight material 57 ensures airtightness between the outer and inner joint frames 34 and 44.

[0013] In this embodiment, the lower frame 32 of the outer shoji screen 3 is provided with a door roller 36 guided by a lower rail 221, and the lower frame 42 of the inner shoji screen 4 is provided with a door roller 46 guided by a lower rail 222. In addition, an upper sliding piece 37 guided by an upper rail 211 is attached to the upper ends of the vertical frame 33 and outer joint frame 34 of the outer shoji screen 3, and an upper sliding piece (not shown) guided by an upper guide groove 212 is attached to the upper ends of the vertical frame 43 and inner joint frame 44 of the inner shoji screen 4. Here, the clearance between the upper sliding piece 37 of the outer shoji 3 and the upper rail 211 is, for example, 0.25 mm. On the other hand, the clearance between the upper sliding piece of the inner shoji 4 and the upper guide groove 212, i.e., the clearance between the indoor surface of the upper sliding piece and the outdoor surface of the dovetail groove forming portion where the airtight material 52 is attached on the indoor hanging piece 213, is, for example, 3.0 mm. Therefore, when the outer shoji 3 and the inner shoji 4 are subjected to positive pressure due to wind pressure, the amount of movement of the inner shoji 44 toward the indoor side is greater than the amount of movement of the outer shoji 34 toward the indoor side. Therefore, the airtight material 57 attached to the inner shoji 44 may move away from the indoor surface of the outer shoji 34, potentially reducing airtightness. For this reason, in this embodiment, a guide part 60 is attached to the outer joint frame 34 to reduce the amount of movement of the inner joint frame 44 toward the indoor side when subjected to positive pressure, and the airtightness provided by the airtight material 57 is maintained by maintaining an appropriate distance between the outer joint frame 34 and the inner joint frame 44 in the indoor / outdoor directions.

[0014] As shown in Figure 3, smoke deflectors 342, 442 are provided continuously over approximately the entire length of the outer and inner joint frames 34 and 44, respectively, on the indoor-side side wall 341 of the outer joint frame 34 and the outdoor-side side wall 441 of the inner joint frame 44 that faces this side wall 341. The smoke deflector portion 342 of the outer joint frame 34 extends from the end of the side wall portion 341 on the vertical frame 24 side toward the interior of the room, and further extends toward the vertical frame 23 side, forming a hook shape. The smoke deflector portion 442 of the inner joint frame 44 extends from the side wall portion 441 toward the exterior of the room, and further extends toward the vertical frame 24 side, forming a hook shape. Therefore, when the outer shoji screen 3 and the inner shoji screen 4 are closed, the smoke deflector portions 342, 442 engage with each other, and the outer joint frame 34 and the inner joint frame 44 are drawn toward each other.

[0015] Guide parts 60 are attached to the recessed groove defined by the side wall part 341 and the smoke deflector part 342 of the outer joint frame 34. The guide parts 60 are attached to three locations, for example, the upper end side, the lower end side, and the middle part in the vertical direction of the outer joint frame 34. The attachment locations and number of guide parts 60 may be determined according to the height dimensions of the outer shoji screen 3 and the inner shoji screen 4, etc. In this embodiment, the outer sash 34 to which the guide part 60 is attached is the first sash, and the outer shoji screen 3 is the first shoji screen. Also, when the outer shoji screen 3 is placed in the closed position, the inner sash 44 placed on the indoor side of the outer sash 34 is the second sash, and the inner shoji screen 4 is the second shoji screen. The side wall portion 341 of the outer sash 34 is the first side wall portion, and the smoke deflector portion 342 is the first smoke deflector portion, and the side wall portion 441 of the inner sash 44 is the second side wall portion, and the smoke deflector portion 442 is the second smoke deflector portion. The side wall portion 341 is formed with a first through hole 345, which serves as a first recess for mounting the guide component 60, and the smoke deflector portion 342 is formed with a second through hole 346, which serves as a second recess for mounting the guide component 60. The first through hole 345 and the second through hole 346 are circular through holes, and as shown in FIG. 4 , the first through hole 345 is formed at a position closer to the vertical frame 23 than the tip of the smoke deflector portion 342. Therefore, when the exterior joint frame 34 is viewed from the inside of the room, the first through hole 345 is not hidden by the smoke deflector portion 342. Therefore, both the first through hole 345 and the second through hole 346 are visible when the exterior joint frame 34 is viewed from the inside of the room.

[0016] Next, the guide component 60 will be described with reference to Figures 5 and 6. Figure 6 is a cross-sectional view taken along line VV in Figure 5(A). The guide part 60 is a molded product made of synthetic resin, and comprises a first extension piece 61 arranged along the side wall part 341 which is the first side wall part, a second extension piece 62 arranged along the smoke return part 342, and a connecting piece 63 connecting the first extension piece 61 and the second extension piece 62. The first extension piece 61 has an abutment surface 611 that abuts against the side wall portion 341, and a first protrusion 64 that protrudes toward the side wall portion 341 is formed on the abutment surface 611. The first protrusion 64 is formed on the tip side of the first extension piece 61. In addition, a slope 612 is formed on the tip of the first extension piece 61. The length dimension of the first extension piece 61 in the sliding direction of the outer screen 3, i.e., the left-right direction of the sliding window 1, is greater than the left-right length dimensions of the second extension piece 62 and the smoke deflector portion 342, as shown in Figure 3. Furthermore, the left-right length dimension of the first extension piece 61 is greater than the left-right dimension of the smoke deflector portion 442 of the inner joint frame 44. The second extension piece 62 has an abutment surface 621 that abuts against the smoke deflector portion 342, and a second protrusion 65 that protrudes toward the smoke deflector portion 342 is formed on the abutment surface 621. The second protrusion 65 is formed on the tip side of the second extension piece 62. In addition, a slope 622 is formed on the tip of the second extension piece 62. The left-right dimension of the second extension piece 62 is smaller than the left-right dimension of the smoke deflector portion 342. However, the length is set so that the tip of the smoke deflector portion 442 can abut against the second extension piece 62 when the outer shoji screen 3 and inner shoji screen 4 are closed.

[0017] As shown in FIGS. 5(A) and 5(D), the first protrusion 64 and the second protrusion 65 are formed as substantially circular protrusions in a side view to match the shapes of the first through-hole 345 and the second through-hole 346. 6, the first protrusion 64 has a guide surface 641 on the base end side of the first extension piece 61, i.e., on the connecting piece 63 side, and a locking surface 642 on the tip side of the first extension piece 61. The first inclination angle, which is the inclination angle of the guide surface 641 with respect to the abutment surface 611, is approximately 30 degrees, and the second inclination angle, which is the inclination angle of the locking surface 642 with respect to the abutment surface 611, is approximately 80 degrees. The second protrusion 65 has a guide surface 651 on the base end side of the second extension piece 62, i.e., on the connecting piece 63 side, and a locking surface 652 on the tip side of the second extension piece 62. A first inclination angle, which is the inclination angle of the guide surface 651 relative to the abutment surface 621, is approximately 30 degrees, and a second inclination angle, which is the inclination angle of the locking surface 652 relative to the abutment surface 621, is approximately 80 degrees. Therefore, the first inclination angle of the guide surfaces 641, 651 of the first protrusion 64 and the second protrusion 65 is set to be an angle smaller than the second inclination angle of the locking surfaces 642, 652. A recess 623 is formed on the contact surface 621 of the second extending piece 62 around the second protrusion 65. This reduces the thickness of the second extending piece 62 around the second protrusion 65. Because the recess 623 thins the second extending piece 62, the second extending piece 62, which has a shorter extension dimension from the connecting piece 63 than the first extending piece 61, is also configured to be able to elastically deform.

[0018] The first extension piece 61 and the second extension piece 62 of the guide component 60 extend in directions that move away from each other as they move from the base end, i.e., the connecting piece 63 side, toward the tip end. Therefore, as shown in FIG. 4 , when the guide component 60 is inserted between the side wall portion 341 and the smoke deflector portion 342, the tip ends of the first extension piece 61 and the second extension piece 62 bend in directions that move toward each other. Furthermore, when the guide surfaces 641, 651 of the first protrusion 64 and the second protrusion 65 abut against the side wall portion 341 and the smoke deflector portion 342, the first inclination angle of the guide surfaces 641, 651 is small, at approximately 30 degrees, so that the first extension piece 61 and the second extension piece 62 are deformed, allowing the guide component 60 to be smoothly inserted between the side wall portion 341 and the smoke deflector portion 342. Then, the first protrusion 64 is inserted into the first through-hole 345, and the second protrusion 65 is inserted into the second through-hole 346, causing the elastically deformed first extension piece 61 and second extension piece 62 to abut against the side wall portion 341 and the smoke deflector portion 342, thereby attaching the guide component 60. At this time, the first extension piece 61 and the second extension piece 62 abut against the side wall portion 341 and the smoke deflector portion 342 and are slightly elastically deformed toward each other, and the reaction force causes the abutment surface 611 of the first extension piece 61 and the abutment surface 621 of the second extension piece 62 to be pressed against the side wall portion 341 and the smoke deflector portion 342. Therefore, the guide component 60 can be easily attached to the outer joint frame 34 by simply pushing it between the side wall portion 341 and the smoke deflector portion 342, as shown in FIG. 4 .

[0019] When the outer shoji screen 3 and the inner shoji screen 4 are moved to their respective closed positions, the smoke deflector portion 442 of the inner shoji screen 44 is inserted between the first extension piece 61 and the second extension piece 62 of the guide part 60 of the outer shoji screen 34. When the outer shoji screen 3 and the inner shoji screen 4 are closed, if the inner shoji screen 4 is closer to the outside of the room relative to the outer shoji screen 3, the tip of the smoke deflector portion 442 is guided by the slope 612, moving the inner shoji screen 44 closer to the inside of the room, allowing the appropriate distance between the outer shoji screen 3 and the inner shoji screen 4. Also, when the outer shoji screen 3 and the inner shoji screen 4 are closed, if the inner shoji screen 4 is closer to the inside of the room relative to the outer shoji screen 3, the tip of the smoke deflector portion 442 is guided by the slope 622, moving the inner shoji screen 44 closer to the outside of the room, allowing the appropriate distance between the outer shoji screen 3 and the inner shoji screen 4. Furthermore, by arranging the smoke deflector section 442 between the first extension piece 61 and the second extension piece 62, the outer shoji screen 3 and the inner shoji screen 4 can be pulled together to maintain an appropriate distance between the interior and exterior directions, and the airtight material 57 attached to the inner joint frame 44 can be securely abutted against the outer joint frame 34 to maintain airtightness.

[0020] [Effects of the embodiment] According to this embodiment, the first protrusion 64 of the first extension piece 61 is inserted into the first through-hole 345 of the side wall 341, and the second protrusion 65 of the second extension piece 62 is inserted into the second through-hole 346 of the smoke deflector 342. This allows the guide component 60 to be securely attached to the outer sill 34 and prevents the guide component 60 from falling off. That is, when the outer and inner shoji screens 3 and 4 are closed, wind pressure may cause one of the shoji screens to move toward the outside or inside of the room, causing the tip of the smoke deflector 442 to collide with the tip of the first extension piece 61 or the second extension piece 62. Even if the first extension piece 61 or the second extension piece 62 moves to some extent away from the side wall 341 or the smoke deflector 342, the first protrusion 64 and the second protrusion 65 will not come off the first through-hole 345 and the second through-hole 346, improving the retention effect of the guide component 60. Furthermore, even if one of the first protrusion portion 64 or the second protrusion portion 65 comes out of the first through hole 345 or the second through hole 346, the other of the first protrusion portion 64 or the second protrusion portion 65 remains inserted into the first through hole 345 or the second through hole 346, thereby preventing the guide part 60 from falling off and further improving the holding effect of the guide part 60. Furthermore, by opening the outer shoji screen 3 and the inner shoji screen 4, the abutment between the smoke deflector portion 442 and the guide part 60 is released, and the first protrusion portion 64 or the second protrusion portion 65 that has come out of the first through hole 345 or the second through hole 346 is reinserted into the first through hole 345 or the second through hole 346, thereby maintaining the attached state of the guide part 60. This reduces the risk of the guide part 60 attached to the outer joint frame 34 coming off. Also, since it is only necessary to form the first through hole 345 and the second through hole 346 in the outer joint frame 34, the manufacturing cost of the outer joint frame 34 can also be reduced.

[0021] Because the abutment surface 611 of the first extension piece 61 abuts against the side wall portion 341 and the abutment surface 621 of the second extension piece 62 abuts against the smoke deflector portion 342, it is possible to prevent a gap from being formed between the tips of the first extension piece 61 and the second extension piece 62 and the outer joint frame 34. This prevents the smoke deflector portion 442 of the inner joint frame 44 from getting into the gap between the first extension piece 61 and the second extension piece 62 and the outer joint frame 34 when the outer shoji screen 3 and the inner shoji screen 4 are closed. Therefore, even if the smoke deflector portion 442 abuts against the tips of the first extension piece 61 and the second extension piece 62, it is possible to smoothly guide the smoke deflector portion 442 between the first extension piece 61 and the second extension piece 62, and it is possible to properly maintain the distance between the outer shoji screen 3 and the inner shoji screen 4. Furthermore, since each abutment surface 611, 621 of the guide part 60 abuts against the side wall portion 341 and the smoke deflector portion 342, it is possible to prevent gaps from occurring between the guide part 60 and the side wall portion 341 and the smoke deflector portion 342. This prevents noise from the guide part 60 that would occur if a gap were to exist and the first extension piece 61 and the second extension piece 62 were to deform and collide with the side wall portion 341 and the smoke deflector portion 342, and it is possible to stably attach the guide part 60 to the outer joint frame 34.

[0022] The first recess and second recess into which the first protrusion 64 and second protrusion 65 are inserted are configured by the first through hole 345 and the second through hole 346, so the first recess and the second recess can be easily formed by drilling. Furthermore, when attaching the guide component 60 to the outer joint frame 34, the second protrusion 65 can be seen from the second through hole 346, so the second protrusion 65 can be easily inserted into the second through hole 346, and the first protrusion 64, which is at the same height as the second protrusion 65, can also be easily inserted into the first through hole 345, improving the ease of attachment of the guide component 60. Furthermore, when removing the guide part 60 from the outer joint frame 34, a jig or the like can be inserted into the first through hole 345 or the second through hole 346 and the first protrusion 64 or the second protrusion 65 can be pushed in to remove the guide part 60 from the first through hole 345 or the second through hole 346, and the guide part 60 can also be easily removed from the outer joint frame 34. Since the left-right dimension of the second extension piece 62 is shorter than the left-right dimension of the smoke deflector portion 342, the second extension piece 62 is less likely to fall toward the outside of the room, and the second protrusion portion 65 can be prevented from coming off the second through hole 346. The left-right dimension of the first extension piece 61 is longer than the left-right dimension of the smoke deflector portion 442, so that the entire smoke deflector portion 442 can be brought into contact with the first extension piece 61, thereby preventing the inner joint frame 44 from twisting.

[0023] [Variations] The present invention is not limited to the configuration of the above embodiment. The guide component is not limited to being attached to the outer joint frame 34, but may also be attached to the inner joint frame 44. That is, as shown in FIG. 7, a first through hole 445 and a second through hole 446 are formed in the side wall portion 441 and the smoke deflector portion 442 of the inner joint frame 44. Then, the guide component 60B is arranged between the side wall portion 441 and the smoke deflector portion 442, and the first protrusion portion 64 of the first extension piece 61 is inserted into the first through hole 445, and the second protrusion portion 65 of the second extension piece 62 is inserted into the second through hole 446. In this modification, the inner joint frame 44 to which the guide component 60B is attached is the first joint frame, and the inner shoji screen 4 is the first shoji screen. Furthermore, when the inner shoji screen 4 is positioned in the closed position, the outer shoji screen 34, which is positioned on the outside of the inner shoji screen 44, is the second shoji screen, and the outer shoji screen 3 is the second shoji screen. The side wall portion 441 of the inner shoji screen 44 is the first side wall portion, the smoke deflector portion 442 is the first smoke deflector portion, and the side wall portion 341 of the outer shoji screen 34 is the second side wall portion, and the smoke deflector portion 342 is the second smoke deflector portion. In this way, even when the guide part 60B is attached to the inner shoji screen 44, the same effect as in the above embodiment can be achieved. Furthermore, the first shoji screen to which the guide component is attached is not limited to a movable shoji screen that slides in the opening and closing direction, but may also be a fixed shoji screen that is fixed to the window frame.

[0024] 8, a guide component 60C may be used that has a first extending piece 61C in which the abutment surface 611 is formed only on the tip end side, and the remaining portion is a spaced surface 615 spaced away from the side wall portion 341. Similarly, a guide component may be used that has a second extending piece in which the abutment surface 621 is formed only on the tip end side, and the remaining portion is a spaced surface spaced away from the smoke deflector portion 342.

[0025] The first recess and the second recess are not limited to the first through hole 345 and the second through hole 346, but may be formed as recesses that do not penetrate the side wall portion 341 or the smoke deflector portion 342. However, through holes have the advantage that they can be processed more easily and that the second protrusion portion 65 can be seen from the second through hole 346. The shapes of the first protrusion 64 and the second protrusion 65 are not limited to those in the above embodiment, and may be, for example, approximately hemispherical protrusions, as long as they can be inserted into the first recess and the second recess to attach the guide part to the joint frame. The fittings of the present invention are not limited to the sliding window 1, but may also be single sliding windows, casement windows, entrance sliding doors, etc. In other words, any fittings that have a shoji screen (including a door) that can slide in the opening and closing directions relative to the fitting frame may be used.

[0026] [summary] The present invention is a fitting in which at least one of a first shoji screen or a second shoji screen slides in an opening / closing direction, the first shoji screen having a first joining frame, the second shoji screen having a second joining frame, the first joining frame having a first side wall portion facing the second joining frame and a first smoke deflector portion formed continuously from the first side wall portion, the second joining frame having a second side wall portion facing the first joining frame and a second smoke deflector portion formed continuously from the second side wall portion, a guide part being disposed between the first side wall portion and the first smoke deflector portion, the guide part being disposed along the first side wall portion. a first extension piece arranged along the first side wall portion, a second extension piece arranged along the first smoke deflector portion, and a connecting piece connecting the first extension piece and the second extension piece, wherein the first extension piece is formed with a first protrusion protruding toward the first side wall portion, and the second extension piece is formed with a second protrusion protruding toward the first smoke deflector portion, and the guide component is attached to the first side wall portion and the first smoke deflector portion by inserting the first protrusion into a first recess formed in the first side wall portion and inserting the second protrusion into a second recess formed in the first smoke deflector portion. According to the present invention, the guide component attached to the first stile includes a first protrusion inserted into a first recess in the first side wall and a second protrusion inserted into a second recess in the first smoke deflector. These protrusions protrude in opposite directions, toward the exterior and interior of the room. Therefore, when the guide component abuts against the second smoke deflector, even if the first or second extension piece moves somewhat away from the first side wall or the first smoke deflector, the protrusions remain in the recesses, enhancing the retention of the guide component. Furthermore, even if one protrusion disengages from the recess, the other protrusion remains inserted, preventing the guide component from falling off and further enhancing the retention of the guide component. This reduces the risk of the guide component being disengaged from the stile. Furthermore, since only a recess needs to be formed in the first stile, the manufacturing cost of the stile can be reduced.

[0027] In the fitting of the present invention, it is preferable that at least one of the tip of the first extension piece and the tip of the second extension piece abuts against at least one of the first side wall portion and the first smoke deflector portion. According to the present invention, because the tips of the first and second extension pieces abut against the first side wall and the first smoke deflector, gaps can be prevented from occurring between the tips of the extension pieces and the first joining frame. This prevents the second smoke deflector from getting into the gap between the extension pieces and the first joining frame when the shoji screen is closed, and even if the second smoke deflector abuts against the tip of an extension piece, it can be smoothly guided between the first and second extension pieces, maintaining an appropriate distance between the shoji screens.

[0028] In the fitting of the present invention, it is preferable that the first extension piece abuts against the first side wall portion, and the second extension piece abuts against the first smoke deflector portion. According to the present invention, each extension piece of the guide part abuts against the first side wall portion and the first smoke deflector portion of the first joint frame, thereby preventing the guide part from making noise and allowing the guide part to be stably attached to the first joint frame.

[0029] In the building fixture of the present invention, it is preferable that the first recess is composed of a first through hole that penetrates the first side wall portion, and the second recess is composed of a second through hole that penetrates the first smoke deflector portion. According to the present invention, the first and second recesses are formed as through-holes, which makes manufacturing easy. Furthermore, when attaching the guide component to the first joint frame, the protrusion of the guide component is visible through the through-hole, which improves the ease of installation.

[0030] In the fitting of the present invention, it is preferable that the width dimension of the second extension piece along the sliding direction of the shoji screen is shorter than the width dimension of the first smoke deflector portion. According to the present invention, the dimension of the second extension piece in the sliding direction of the shoji screen is shorter than the dimension of the first smoke deflector portion in the left-right direction, making it difficult for the second extension piece to deform and preventing the second protrusion portion from coming off the second recess.

[0031] In the fitting of the present invention, it is preferable that the width dimension of the first extension piece along the sliding direction of the shoji screen is equal to or greater than the width dimension of the second smoke deflector portion. According to the present invention, the entire second smoke deflector portion can be abutted against the first extension piece, thereby preventing the second joint frame from twisting.

[0032] In the building fixture of the present invention, the first protrusion and the second protrusion have a guide surface formed on the connecting piece side and a locking surface formed on the tip side of the first extension piece and the tip side of the second extension piece, and it is preferable that the first inclination angle, which is the inclination angle of the guide surface with respect to the sliding direction of the shoji screen, is smaller than the second inclination angle, which is the inclination angle of the locking surface with respect to the sliding direction. According to the present invention, the first inclination angle of the guide surface of each protrusion is smaller than the second inclination angle of the locking surface of each protrusion, allowing each protrusion to have an arrowhead-shaped cross section. Therefore, the first inclination angle of the guide surface of each protrusion can be made small, approximately 30 degrees, allowing the first extension piece and the second extension piece to be smoothly inserted when the guide component is inserted between the first side wall portion and the first smoke deflector portion from the connecting piece side. Furthermore, the second inclination angle of the locking surface of each protrusion can be made large, approximately 80 degrees, making it difficult for each protrusion to come out of the recess when inserted into the recess, further improving the retention effect of the guide component.

[0033] In the fitting of the present invention, it is preferable that the first recess is formed in a position that does not overlap with the first smoke deflector portion in the front direction. According to the present invention, the first recess is formed at a position that does not overlap with the first smoke deflector portion in the forward direction, and therefore the first recess can be easily processed.
