Description

[Technical field]

[0001] The present disclosure relates to a sash structure. [Background technology]

[0002] Conventionally, large fittings with large lighting sections are known. Since the number of shoji screens increases in large fittings, the number of screen screens also increases when screen screens are provided on the shoji screens. Therefore, a sash structure with multiple screen screens installed in a sliding manner has been proposed (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-8600 A Summary of the Invention [Problem to be solved by the invention]

[0004] When opening a window for ventilation or air intake, the screen door is moved to a specified position in accordance with the opened screen door after the screen door is opened to prevent insects from entering. If the screen door and screen door overlap in a misaligned position, there is a risk of insects entering. Therefore, if there are many screen doors and screen doors, the user is required to perform very complicated operations. [Means for solving the problem]

[0005] The present disclosure relates to a sash structure comprising a plurality of screen doors, a plurality of screen doors arranged on the outside of the plurality of screen doors, and a connection part capable of connecting and separating an inner screen door on the inside of the plurality of screen doors and an outer screen door on the outside of the plurality of screen doors, wherein the inner screen doors and the outer screen doors can move in conjunction with each other while connected by the connection part.

[0007] A first embodiment of the present disclosure will be described in detail below with reference to the drawings. A sash structure 1 of the first embodiment is provided in a large sliding window 100 installed in a building 200, for example. As shown in Fig. 1, the sash structure 1 has a frame 2, a plurality of shoji screens 3, a plurality of screen doors 4, a screen door attachment 5 (see Fig. 2), and a connection part 6 (see Fig. 3A). In the sash structure 1, six shoji screens 3 and four screen doors 4 are arranged so as to be movable in the viewing direction.

[0008] In this specification, the appearance direction refers to the left-right direction when viewed from the front of the sliding window 100, and the look-out direction refers to the indoor-outdoor direction of the sliding window 100. The up-down direction refers to the top-to-bottom direction. With regard to the appearance direction, the outside appearance direction refers to the side closer to the edge of the sliding window 100 in the left-to-right direction, and the inside appearance direction refers to the side closer to the center in the left-to-right direction.

[0009] The frame body 2 is a frame assembled in a rectangular shape around a substantially rectangular opening 201 in which the sliding window 100 is disposed. The frame body 2 has an upper frame 21 and a lower frame 22 (see FIG. 2), each of which is long, and a pair of vertical frames 23.

[0010] The upper frame 21 is a molded member arranged to extend substantially horizontally in the front direction along the upper edge of the opening 201. The upper frame 21 has a plurality of shoji engagement pieces 211 protruding downward and an upper first rail portion 212. The shoji engagement pieces 211 protrude downward in three pieces at intervals in the front direction of the upper frame 21. The shoji engagement pieces 211 extend from one side to the other in the front direction of the upper frame 21. The shoji engagement pieces 211 are inserted into the upper frame 31 of the shoji 3 described later. The upper first rail portion 212 protrudes downward at a position away from the shoji engagement piece 211 located at the outermost side of the room to the outside. The upper first rail portion 212 is a protruding portion with which the screen door 4 described later engages when one screen door 4 is provided. The upper first rail portion 212 extends from one side to the other in the front direction of the upper frame 21.

[0011] The bottom frame 22 is a mold member arranged to extend substantially horizontally in the front direction along the lower edge of the opening 201. The bottom frame 22 has a roller rail portion 221 and a lower first rail portion 222. Three roller rail portions 221 are arranged at intervals in the front direction of the bottom frame 22. A roller 32a described later engages with the roller rail portion 221 to allow the shoji screen 3 to slide. The lower first rail portion 222 protrudes upward at a position away from the roller rail portion 221 located on the outermost side of the room to the outside. The lower first rail portion 222 is a protruding portion with which the screen door 4 described later engages when one screen door 4 is provided. The lower first rail portion 222 extends from one side of the bottom frame 22 to the other side in the front direction.

[0012] 1, the vertical frame 23 extends in the vertical direction of the opening 201 and is arranged so as to connect the upper frame 21 and the lower frame 22 at both ends of the upper frame 21 and the lower frame 22. The vertical frame 23 is configured so that three shoji screens 3 can be arranged in the prospective direction.

[0013] The screen door attachment 5 is a component that is attached to the upper frame 21 and the lower frame 22 when the upper frame 21 and the lower frame 22 are shaped so that only one screen door 4 can be attached thereto, and that arranges the screen door 4 (described later) in a sliding manner. The screen door attachment 5 has an upper attachment 51 and a lower attachment 52.

[0014] The upper attachment 51 is fixed to the front side of the upper frame 21 and has an upper surface 51a that is continuous with the upper surface of the upper frame 21, and a front surface 51b that extends in the vertical direction at the outermost side of the room. The upper attachment 51 has an upper second rail portion 511 that extends in the front direction parallel to the upper first rail portion 212 of the upper frame 21 from the lower end of the front surface 51b toward the inside of the room in the front direction.

[0015] The lower attachment 52 is fixed to the front side of the lower frame 22. The lower attachment 52 has a lower surface 52a extending from the lower frame 22 toward the outside of the room in the viewing direction, and a front surface 52b extending in the vertical direction at the outermost side of the room. The lower attachment 52 has a lower second rail portion 521 extending in the viewing direction parallel to the lower first rail portion 222 of the lower frame 22 from the upper end of the front surface 52b toward the inside of the room in the viewing direction.

[0016] The upper first rail portion 212 and the lower first rail portion 222 provide one rail on the indoor side along which the screen door 4 can move, and the upper second rail portion 511 and the lower second rail portion 521 provide one rail on the outdoor side along which the screen door 4 can move, for a total of two rails. This allows the screen door 4 to move in a sliding manner on the two rails on the indoor and outdoor sides. For example, if two of the six shoji screens 3 are opened to one side in the front view and two to the other, four screen doors 4 can be placed consecutively on the inside of the front view. If all six shoji screens 3 are moved to either the left or right, four screen doors can be placed in the remaining opening.

[0017] The left and right ends of the upper attachment 51 and the lower attachment 52 in the front direction are provided with anti-falling members for the screen door 4 (not shown). The anti-falling members may be, for example, stopper parts or protrusions of the sash frame extending to the outside of the front direction. By providing the anti-falling members for the screen door 4, it is possible to prevent the screen door 4 from falling off without providing attachments that extend vertically at the left and right ends of the screen door 4 in the front direction.

[0018] Six shoji screens 3 are arranged inside the frame 2 so that they can move freely in the viewing direction. Of the multiple shoji screens 3, the shoji screen 3 arranged on the outside of the room is called the inner shoji screen 310, the shoji screen 3 arranged on the outside of the room is called the outer shoji screen 330, and the shoji screen 3 arranged between the inner shoji screen 310 and the outer shoji screen 330 is called the middle shoji screen 320. Each of the shoji screens 3 has a frame 30 and a glass section 35. As shown in Figures 1 and 2, each of the frames 30 has a long upper frame 31, a lower frame 32, and a pair of vertical frames 33. The frame 30 is formed in a roughly U-shape in cross section, opening toward the inner circumference.

[0019] The upper frame 31 is disposed below the upper frame 21 and extends along the front direction. The upper frame 31 is provided with a slit 311 into which the screen engagement piece 211 of the upper frame 21 is inserted.

[0020] The lower frame 32 is disposed above the lower frame 22 and extends along the front direction. A roller 32a is disposed inside the lower frame 32. The roller 32a engages with the roller rail portion 221 of the lower frame 22, and the roller 32a allows the frame 30 to move in the front direction.

[0021] The vertical frame 33 is disposed inside the vertical frame 23. The vertical frame 33 extends in the vertical direction so as to connect the upper frame 31 and the lower frame 32, and is disposed in a pair on the left and right with a gap therebetween in the front direction.

[0022] Glass section 35 is held on the inner periphery of frame 30 and is a surface material that closes opening 201. Glass section 35 has glass 351 composed of multi-layer glass, spacer 352, and grating channel 353. Glass 351 is arranged between the outside and inside of the room with spacer 352 sandwiched between them. An end of glass 351 is held by grating channel 353, which is a substantially U-shaped elastic member, and is inserted into the inner periphery of frame 30.

[0023] The screen door 4 is placed on the outside of the shoji screen 3, and prevents insects and the like from entering through the opening 201 that is opened when the shoji screen 3 is opened. Multiple screen doors 4 are placed in the viewing direction, and the multiple screen doors 4 include an inner screen door 410 placed on the indoor side and an outer screen door 420 placed on the outdoor side. The screen door 4 has a screen door frame 40, a mesh part 44, a screen door engaging part 45 as an engaging member and an engaged member, and mohair 46 as a blocking member.

[0024] The screen frame 40 is formed by assembling an upper screen frame 41, a lower screen frame 42, and a pair of vertical screen frames 43 into a frame shape. As shown in FIG. 3A, each of the upper screen frame 41, the lower screen frame 42, and the pair of vertical screen frames 43 has a rectangular tubular portion 401 and a pair of extension pieces 402. The rectangular tubular portion 401 has a generally rectangular cross-sectional shape and a hollow structure with a hollow interior. The pair of extension pieces 402 are plate-like portions that extend from the rectangular tubular portion 401 toward the outside of the frame formed by the screen frame 40. The pair of extension pieces 402 has an indoor extension piece 402a and an outdoor extension piece 402b. The indoor extension piece 402a extends outward from the indoor end of the rectangular tubular portion 401, and the outdoor extension piece 402b extends outward from the outdoor end of the rectangular tubular portion 401. The indoor extension piece 402a and the outdoor extension piece 402b extend parallel to each other with a gap between them.

[0025] The upper screen frame 41 is a long shaped member that extends in the front direction at the top of the screen 4. The lower screen frame 42 is a long shaped member that extends in the front direction at the bottom of the screen 4. As shown in FIG. 2, the screen wheel 42a is disposed inside the pair of extension pieces 402 of the lower screen frame 42, and the screen 4 can move in a sliding manner by engaging with the lower first rail portion 222 and the lower second rail portion 521. The vertical screen frame 43 is a shaped member that connects the ends of the upper screen frame 41 and the lower screen frame 42 and extends in the vertical direction. The net portion 44 is a breathable net that can prevent the intrusion of insects and the like. The net portion 44 is disposed inside the frame formed by the screen frame 40 so as to follow the front surface of the screen frame 40 on the outdoor side.

[0026] As shown in Fig. 3, the mohair 46 is disposed between the inner screen door 410 and the outer screen door 420, and between the inner screen door 410 and the outer screen door 330, and is a member that seals the gaps between the inner screen door 410 and the outer screen door 420, and between the inner screen door 410 and the outer screen door 330. The mohair 46 is formed with bristles in which bundles of fibers are aligned from one side to the other, and is disposed in a frame shape around the four periphery of the screen door 4.

[0027] The mohair 46 is arranged between the inner screen 410 and the outer screen 420, and between the inner screen 410 and the outer screen 330. The mohair 46 is fixed to the indoor side of the screen frame 40 (vertical screen frame 43 in FIG. 3A) of the screen 4, and protrudes towards the indoor side in the expected direction. In detail, the mohair 46 is inserted into the mohair attachment portion 403 provided on the indoor extension piece 402a of the screen frame 40.

[0028] As shown in Figure 6, when the outer screen door 420 and the inner screen door 410 are moved from an overlapping state in the forward direction to a state in which they are shifted in the forward direction, the mohair 46 attached to the vertical screen door frame 43 of the outer screen door 420 abuts against the mesh portion 44 of the inner screen door 410.

[0029] The screen door engagement portion 45 is a component that is fixed to the screen door vertical frame 43 of the screen door 4 and connects adjacent screen doors 4. Fig. 3A is a partial enlarged view of the part surrounded by the imaginary line E1 in Fig. 1. Fig. 3B is a partial enlarged view of the part surrounded by the imaginary line E2 in Fig. 1. As shown in Figs. 3A and 3B, the screen door engagement portion 45 has a first screen door engagement portion 451 and a second screen door engagement portion 452. The first screen door engagement portion 451 and the second screen door engagement portion 452 constitute an engaging member and an engaged member, one of which can be engaged with and separated from the other.

[0030] As shown in FIG. 3A, the first screen door engaging portion 451 is a member fixed to the inner screen door 410. The first screen door engaging portion 451 is provided on the screen door vertical frame 43 located on the inner side of the inner screen door 410 in the front direction. Two first screen door engaging portions 451 are attached, one above the screen door vertical frame 43 and one below. The first screen door engaging portion 451 has an exterior side surface 4511, a first engaging portion 4512 as an engaging portion, and a projection piece 4513. The exterior side surface 4511 abuts against the exterior surface of the screen door vertical frame 43 and has a flat surface extending along the front direction. The first engaging portion 4512 has a generally L-shaped cross-sectional shape that protrudes from the exterior side surface 4511 to the exterior side. The first engagement portion 4512 has a short side portion 4512a and a long side portion 4512b, and the short side portion 4512a extends from the inside to the outside in the projection direction. The long side portion 4512b extends from the outside end of the short side portion 4512a in the projection direction. The long side portion 4512b extends approximately parallel to the outside surface of the screen door vertical frame 43. The first engagement portion 4512 is a portion that engages the inner screen door 410 and the outer screen door 420 by engaging with the second engagement portion 4522 described later. The projection piece 4513 extends from the end of the exterior side surface 4511 so as to cover the projection direction of the screen door vertical frame 43. The projection piece 4513 is continuous with the screen door side shoji connection portion 61 described later, and connects the screen door engagement portion 45 and the screen door side shoji connection portion 61.

[0031] The second screen door engaging portion 452 is a member fixed to the outer screen door 420 as shown in FIG. 3B. The second screen door engaging portion 452 is fixed to the screen door frame 43 located on the outer side of the outer screen door 420 in the front direction. The second screen door engaging portion 452 is attached to the positions corresponding to the first screen door engaging portion 451, one above the screen door frame 43 and one below. As shown in FIG. 4, the second screen door engaging portion 452 has an indoor side surface 4521 and a second engaging portion 4522 as an engaging portion. The indoor side surface 4521 abuts against the indoor side surface of the screen door frame 43 and has a flat surface extending along the front direction. The indoor side surface 4521 is fixed to the indoor side surface of the screen door frame 43 of the outer screen door 420 with a screw. The second engagement portion 4522 has a generally L-shaped cross section that protrudes from the indoor side surface 4521 toward the indoor side. The second engagement portion 4522 has a short side portion 4522a and a long side portion 4522b, and the short side portion 4522a extends from the outdoor side to the indoor side in the projection direction. The long side portion 4522b extends in the projection direction from the indoor end of the short side portion 4522a. The long side portion 4522b extends approximately parallel to the indoor surface of the screen door vertical frame 43.

[0032] FIG. 5A is a diagram showing the screen door 4 being moved inward in the face direction. One of the vertical frames 23 is omitted. As shown in FIG. 5A, when the outer screen door 420 is pulled inward in the face direction of the sliding window 100, the second engagement part 4522 fixed to the screen door vertical frame 43 on the outer side in the face direction of the outer screen door 420 engages with the first engagement part 4512 fixed to the screen door vertical frame 43 on the inner side in the face direction of the inner screen door 410, as shown in FIG. 5B. By moving the outer screen door 420, the outer screen door 420 and the inner screen door 410 move inward in the face direction in conjunction with each other while engaged. When moving in the opposite direction, if the screen door vertical frame 43 on the inner side in the face direction of the inner screen door 410 is pushed while the first engagement part 4512 and the second engagement part 4522 are engaged, the outer screen door 420 moves outward in the face direction in conjunction with the inner screen door 410.

[0033] The connection part 6 is a component that separably connects the inner screen door 410 and the outer screen door 330, and configures the inner screen door 410 and the outer screen door 330 to be able to be opened and closed in conjunction with each other. The connection part 6 has a screen door side screen door connection part 61 and a magnet member 62.

[0034] As shown in FIG. 3A and FIG. 5B, the screen door side shoji connection part 61 is a member formed integrally with the first screen door engagement part 451 of the screen door engagement part 45 provided on the inner screen door 410. The screen door side shoji connection part 61 is a surface that bends from the end of the interior side of the projection piece 4513 of the first screen door engagement part 451 and extends in the visible direction. The screen door side shoji connection part 61 has a magnet fixing part 611 and a screen door vertical frame fixing part 612. The magnet fixing part 611 is a flat surface that is connected to the end of the interior side of the projection piece 4513 and extends in the visible direction. A magnet member 62 for attaching to the vertical frame 33 of the shoji door 3 described later is fixed to the magnet fixing part 611. The screen door vertical frame fixing part 612 is a surface that fixes the screen door side shoji connection part 61 to the screen door vertical frame 43 of the inner screen door 410. The screen door vertical frame fixing part 612 is fixed by a screw to the screen door vertical frame 43 on the inside of the inner screen door 410 in the view direction. By fixing the screen door vertical frame fixing part 612 to the screen door vertical frame 43, the first screen door engagement part 451, which is integrally connected to the screen door side shoji connection part 61, is also fixed to the screen door vertical frame 43.

[0035] The magnet member 62 connects the inner screen 410 and the outer screen 330. The magnet member 62 has a magnet 62a, a holding plate 62b, and a screen-side magnet part 63. The magnet 62a is a plate-shaped magnet. The holding plate 62b is a plate that holds the magnet 62a. By screwing the holding plate 62b to the magnet fixing part 611, the magnet 62a is attached to the magnet fixing part 611, and a part having magnetic force is formed on the indoor side of the screen vertical frame 43.

[0036] As shown in FIG. 3A, the screen side magnet part 63 is fixed to the vertical frame 33 on the inside of the outer screen 330 in the view direction. The screen side magnet part 63 is a plate-shaped magnet fixed to the exterior side surface of the vertical frame 33, and is bent in a generally L-shape in cross section so as to cover the exterior side surface of the vertical frame 33 and the view surface 33a. The screen side magnet part 63 may be made of iron or magnetizable stainless steel. The screen side magnet part 63 is disposed in a position facing the magnet fixing part 611 of the screen side screen connection part 61. The magnet member 62 is attached to the magnet fixing part 611. Therefore, as shown in FIG. 6, when the inner screen 410 is placed on the outer screen 330, the magnet 62a of the magnet member 62 and the screen side magnet part 63 attract each other by magnetic force and adhere to each other, and the inner screen 410 and the outer screen 330 are connected.

[0037] As shown in Figure 6, when the outer screen 330 is pulled inward in the front view so that it overlaps with the middle screen 320, the inner screen door 410 moves in conjunction with the outer screen 330 while connected by the connection part 6, since the inner screen door 410 is connected to the outer screen 330. The inner screen door 410 is arranged to cover the outside of the outer screen 330. Therefore, when the inner screen door 410 moves in the front view, the mohair 46 attached to the screen door vertical frame 43 on the inside of the outer screen door 420 in the front view slides while abutting against the mesh part 44 of the inner screen door 410.

[0038] According to the first embodiment, the following effects are achieved. The sash structure 1 includes a plurality of screens 3, a plurality of screens 4 arranged on the exterior side of the plurality of screens 3, an inner screen 410 on the interior side of the plurality of screens 4, and a connection part 6 that can connect and separate the outer screen 330 on the exterior side of the plurality of screens 3, and the inner screen 410 and the outer screen 330 are configured to be movable in conjunction with each other while connected by the connection part 6. The inner screen 410 and the outer screen 330 are connected by the connection part 6 and move in conjunction with each other. Therefore, the screen 4 and the screen 3 can be moved with a single operation, improving convenience. Furthermore, when the screen 3 and the screen 4 are opened or closed, the position of the vertical frame 33 of the screen 3 and the vertical frame 43 of the screen 4 may be misaligned, and the vertical frame 33 and the vertical frame 43 of the screen may be noticeable. However, because the inner screen door 410 and the outer screen door 330 are connected, the inner screen door 410 and the outer screen door 330 can be moved together while overlapping. This reduces the degree to which the screen door vertical frame 43 of the screen door 4 is visible through the glass 351 in addition to the vertical frame 33 of the screen door 3 when looking at the sliding window 100 from inside the room, which affects the design.

[0039] According to the first embodiment, the connection section 6 is configured to include a magnet member 62 that connects the inner screen door 410 and the outer screen 330. Because the inner screen door 410 and the outer screen 330 are connected by the magnet member 62, it is possible to reduce the space required to connect the inner screen door 410 and the outer screen 330. Furthermore, when separating the inner screen door 410 and the outer screen 330, the user only needs to apply force, which simplifies the opening / closing and moving operations and improves operability.

[0040] The present disclosure is not limited to the above embodiment, and modifications and improvements within the scope of achieving the object of the present disclosure are included in the present disclosure. In the following description, the description of the configuration common to the first embodiment will be omitted, and the same reference numerals will be used.

[0041] In the sliding window 100A according to the first modified example of the first embodiment shown in Figures 7A and 7B, the first screen door engagement portion 451A has the same shape as the second screen door engagement portion 452. That is, by turning the member of the second screen door engagement portion 452 shown in Figure 4 upside down, the indoor side surface 4521 shown in Figure 4 can be fixed to the outdoor side surface of the screen door vertical frame 43 of the inner screen door 410 with a screw as the outdoor side surface 4511A. Similarly, the second engagement portion 4522, which is generally L-shaped in cross section, constitutes the first engagement portion 4512A.

[0042] The sliding window 100A does not have a screen door side door connection part 61, unlike the first embodiment. The magnet member 62A has a flat magnet 62a, a holding plate 62b that is substantially U-shaped in cross section to hold the magnet 62a, and a screen door side magnet part 63A. The magnet 62a of the magnet member 62A is fixed directly to the outdoor extension piece 402b of the screen door vertical frame 43 of the inner screen door 410. As shown in FIG. 7B, the holding plate 62b is disposed between the indoor extension piece 402a and the outdoor extension piece 402b of the screen door vertical frame 43 of the inner screen door 410. The holding plate 62b is longer in the vertical direction than the magnet 62a, and is attached so that the magnet 62a engages with the holding plate 62b in the vertical center. A through hole 43a is formed in a part of the indoor side surface of the screen door vertical frame 43. A part of the retaining plate 62b is inserted through the through hole 43a. The magnet 62a protrudes in the forward direction toward the interior side of the room further than the retaining plate 62b, and protrudes from the through hole 43a to the interior side of the room. By screwing the retaining plate 62b to the interior side of the screen frame 43, a part having magnetic force is formed on the interior side of the screen frame 43. The magnet 62a is attached by magnetic force to the screen side magnet part 63A attached to the exterior side of the frame 33 of the outer screen 330.

[0043] Compared to the first embodiment, the shoji side magnet part 63A does not have a portion that covers the visible surface 33a of the vertical frame 33. The shoji side magnet part 63A is a substantially rectangular plate, and is fixed to the exterior side surface of the vertical frame 33 on the inside of the visible direction of the outer shoji 330.

[0044] According to the first modified example, the first screen door engaging portion 451A and the second screen door engaging portion 452 can be made of the same material, thereby reducing the number of parts.

[0045] In the sliding window 100B according to the second modified example of the first embodiment shown in FIG. 8A and FIG. 8B, the magnet member 62B is attached to the exterior side of the vertical frame 33 of the outer screen 330. The sliding window 100B does not have a screen-side magnet part 63, unlike the first embodiment. As shown in FIG. 8B, the magnet member 62B has a magnet 62a and a holding plate 62b. The holding plate 62b has a generally L-shaped cross section and has an exterior side abutment part 621 along the exterior facing surface of the vertical frame 33, and a projected surface abutment part 622 along the projected surface of the vertical frame 33. The holding plate 62b is made of resin and is configured to hold the magnet 62a on the exterior side abutment part 621.

[0046] In the second modified example, as shown in Fig. 8A, the first screen door engagement portion 451B of the screen door engagement portion 45 and the screen door side screen connection portion 61B are integrally molded. The screen door side screen connection portion 61B is made of a magnetic material, such as iron or magnetic stainless steel, and constitutes a part of the magnet member 62B. The screen door side screen connection portion 61B bends from the indoor side end of the projection piece 4513 of the first screen door engagement portion 451 and extends in the visible direction. The screen door side screen connection portion 61B is directly attached to the magnet 62a, thereby connecting the inner screen door 410 and the outer screen door 330.

[0047] According to the second modification, the first screen door engaging portion 451 and the screen door side screen connection portion 61B can be constructed as an integral member. And, by attaching the magnet member 62B to the vertical frame 33 side of the outer screen 330, the structure of the screen door 4 can be simplified and made lighter.

[0048] In the sliding window 100C according to the second embodiment shown in Figures 9A and 9B, the connection portion 6C has a magnet member 62C and an abutment portion 64. Unlike the first embodiment, the sliding window 100C does not have a screen door-side shoji connection portion 61.

[0049] The first screen engaging portion 451C has a sight piece 4514 that protrudes inward in the sight direction from the sight piece 4513. The sight piece 4514 abuts against the indoor side extension piece 402a of the screen vertical frame 43 of the screen 4 and extends parallel to the indoor side extension piece 402a. The sight piece 4514 is fixed to the indoor side extension piece 402a with a screw.

[0050] The magnet member 62C includes a magnet 62a and a retaining plate 62b. The retaining plate 62b is fixed to the projecting surface 33a of the vertical frame 33 of the outer sash 330.

[0051] The abutment portion 64 extends from the end side of the inner screen 410 in the front direction and extends toward the end of the outer screen 330 in the front direction. The abutment portion 64 is continuous with the front piece 4513 of the first screen engagement portion 451C and is formed integrally with the first screen engagement portion 451C. The abutment portion 64 has a magnetizable member arrangement portion 641 and a screen abutment portion 642. The magnetizable member arrangement portion 641 is slightly bent inward in the front direction from the end portion on the indoor side of the first screen engagement portion 451C. The screen abutment portion 642 is bent at a substantially right angle from the end portion on the inner side in the front direction of the magnetizable member arrangement portion 641 and extends in the front direction. The screen abutment portion 642 extends opposite the front surface 33a of the vertical frame 33 in the outer screen 330. A magnet 643 is fixed to the inner surface of the door abutment portion 642 that faces the front surface 33a of the vertical frame 33. The magnet 643 is a rectangular plate made of a magnetizable material. The thickness of the magnet 643 is smaller than the length of the magnetizable member arrangement space 641 extending in the front direction. The magnet 643 is attached in a position facing the magnet 62a.

[0052] As shown in FIG. 9A, the abutment portion 64 is continuous with the first screen door engagement portion 451C. The abutment portion 64 is provided with a magnet 643, which is attached to the magnet 62a arranged on the projection surface 33a of the vertical frame 33 of the outer screen 330. The abutment portion 64 abuts against the end of the vertical frame 33 of the outer screen 330 in the projection direction via the magnet 643. At the same time, the projection piece 4513 of the first screen door engagement portion 451C abuts against a pair of extension pieces 402 on the vertical frame 43 of the inner screen 410. In this state, if the outer screen 330 is pushed outward in the projection direction, the abutment portion 64, which is magnetically attached to the magnet member 62C by the magnet 643, moves in conjunction with the outer screen 330 as the outer screen 330 moves. As the abutting portion 64 moves, the inner screen door 410, which is pressed by the projection piece 4513 formed integrally with the abutting portion 64, moves.

[0053] Conversely, when the outer screen 330 is pushed inward in the facing direction, the facing surface 33a of the vertical frame 33 of the outer screen 330 pushes the abutment portion 64 inward in the facing direction, so that the outer screen 330 and the inner screen door 410 move in conjunction with each other.

[0054] According to the second embodiment, the first screen door engagement portion 451C and the abutment portion 64 are integrally formed, and the abutment portion 64 can abut against the end of the outer screen 330 in the front direction, so that when the outer screen 330 is moved inward in the front direction, the outer screen 330 and the inner screen 410 can be linked by pushing a physically integrated member. Therefore, more reliable and stable movement is possible. By configuring the outer screen 330 to be linked with the inner screen 410 by a magnet when moving the outer screen 330 outward in the front direction, the configuration and arrangement of the connection portion 6C are not complicated, and manufacturing costs can be reduced and workability can be improved.

[0055] In the sliding window 100D according to the third embodiment shown in Figures 10A and 10B, the connection part 6D has a stopper member 65 as an advancing / retreating engaging member, and an engaged part 66. The stopper member 65 is attached to the vertical frame 33 on the inside of the outer screen 330 in the viewing direction so as to be able to advance and retreat freely relative to the inner screen 410. The stopper member 65 has a stopper fixing part 651, an urging part 652, and a protruding engaging part 653.

[0056] As shown in FIG. 10B, the stopper fixing portion 651 has a fixing portion main body portion 6511 and a through hole arrangement portion 6512. The fixing portion main body portion 6511 has a predetermined thickness and has a hollow space inside, and has an abutment surface 6511a, an exterior side surface 6511b, an interior side surface 6511c, a projected outer portion 6511d, and an engagement claw 6511e. The abutment surface 6511a is a flat surface that can abut against the projected surface of the vertical frame 33. The exterior side surface 6511b is a surface that extends in the visual direction from the exterior end of the abutment surface 6511a. The interior side surface 6511c is a surface that extends in the visual direction opposite the exterior side surface 6511b. The projection outer portion 6511d is located at a position opposite to the abutment surface 6511a, and is a side portion connecting the exterior side surface 6511b and the indoor side surface 6511c. The projection outer portion 6511d extends from the exterior side surface 6511b toward the indoor side surface in the projection direction, bends in the projection direction near the center of the projection direction, moves away from the abutment surface 6511a, and then extends to the end of the indoor side surface 6511c in the projection direction. The engagement claw 6511e is formed on the projection outer portion 6511d and is a cantilever-shaped portion that can be elastically deformed. The tip of the engagement claw 6511e bulges out from the base end side so as to be able to engage with the protruding engagement portion 653 described later.

[0057] The through hole arrangement portion 6512 is a substantially semicircular portion in which a through hole 6512a through which a screw can be inserted is formed, and extends from each of the upper and lower ends of the fixing portion main body portion 6511.

[0058] The protruding engagement portion 653 is a movable part that can engage with the fixing portion main body portion 6511 and move forward and backward toward the outside and inside of the room. The protruding engagement portion 653 has a protruding main body portion 6531 and an engagement claw 6532. The protruding main body portion 6531 is bent along the bent shape of the projected outside portion 6511d of the stopper fixing portion 651 and engages with the outer surface of the projected outside portion 6511d. The protruding main body portion 6531 engages with the projected outside portion 6511d and is arranged so as to be slidable in the indoor and outdoor directions. As shown in FIG. 10A, the tip of the protruding main body portion 6531 on the outdoor side is arranged so as to be able to engage with the engaged portion 66 described later, and is arranged so as to be able to engage with the end of the indoor side extension piece 402a of the screen vertical frame 43 of the inner screen 410. The indoor side of the protruding main body portion 6531 abuts against the side surface of the indoor side portion of the projected outside portion 6511d. The engagement claw 6532 is disposed on the fixing portion main body 6511 side of the protruding main body 6531 so as to be able to engage with the engagement claw 6511e of the stopper fixing portion 651. The engagement claw 6532 extends in a cantilever shape from the outside to the inside of the room near the center of the protruding main body 6531 in the projection direction, with the tip side bulging out more than the base end side.

[0059] The biasing portion 652 is a coil spring disposed inside the fixing portion main body 6511. The biasing portion 652 abuts against the protruding engagement portion 653 so as to constantly bias the protruding engagement portion 653 toward the exterior side.

[0060] As shown in FIG. 10A, the engaged portion 66 is fixed to the screen frame 43 on the inner side of the inner screen 410 in the projection direction. As shown in FIG. 10A, the engaged portion 66 has a shape in which two parts that are approximately L-shaped in cross section are connected. The engaged portion 66 has a screen fixing portion 661 and a stopper engaging portion 662. The screen fixing portion 661 has a fixing surface 661a and a projection surface 661b. The fixing surface 661a is fixed to the indoor surface of the outdoor extension piece 402b of the screen frame 43 of the inner screen 410 with a screw. The projection surface 661b is a surface that bends at an approximately right angle from the fixing surface 661a and extends in the projection direction. The stopper engaging portion 662 has an engagement projection surface 662a and an engagement projection surface 662b. The engagement prospective surface 662a is a surface that bends at a right angle from the indoor end of the prospective surface 661b of the screen fixing portion 661 and extends in the prospective direction. The engagement prospective surface 662a is a surface that abuts against the protruding engagement portion 653 of the stopper member 65. In detail, the outdoor end of the protruding main body portion 6531 of the protruding engagement portion 653 abuts against the indoor surface of the engagement prospective surface 662a. The engagement prospective surface 662b faces the end that extends in the prospective direction from the outdoor end of the protruding main body portion 6531. The engagement prospective surface 662a and the engagement prospective surface 662b are arranged to cover the outdoor end of the protruding main body portion 6531, and the protruding main body portion 6531 engages with the corner formed by the engagement prospective surface 662a and the engagement prospective surface 662b, so that the stopper member 65 engages with the engaged portion 66.

[0061] The stopper member 65 is always biased by the biasing portion 652, so that the protruding engagement portion 653 of the stopper member 65 is inserted between the stopper engagement portion 662 of the engaged portion 66 and the indoor extension piece 402a of the screen vertical frame 43 and engaged. This connects the inner screen 410 and the outer screen 330. If the end of the outer screen 330 in the front direction is pushed toward the outside in the front direction, the tip side of the protruding engagement portion 653 simultaneously pushes the indoor extension piece 402a of the screen vertical frame 43, so that the outer screen 330 and the inner screen 410 move and move in conjunction with each other. Conversely, if the outer screen 330 is pushed toward the inside in the front direction, the tip side of the protruding engagement portion 653 pushes the engagement projection surface 662b of the stopper engagement portion 662, so that the outer screen 330 and the inner screen 410 move and move in conjunction with each other.

[0062] If it is not desired to link the movements of the outer screen 330 and the inner screen 410, the stopper member 65 can be disengaged from the engaged portion 66. Specifically, when the user places his / her hand on the protruding engagement portion 653 and pulls it toward the inside of the room, the biasing portion 652 contracts. At this time, as shown in FIG. 10B, the engagement claw 6532 provided on the protruding main body portion 6531 side elastically deforms and engages with the engagement claw 6511e provided on the projected outer portion 6511d of the stopper fixing portion 651. When the engagement claw 6532 of the protruding main body portion 6531 and the engagement claw 6511e of the stopper fixing portion 651 engage with each other, the protruding main body portion 6531 is fixed in a state of being pulled toward the inside of the room, and the engagement between the outer screen 330 and the inner screen 410 is released. Therefore, the outer screen 330 and the inner screen 410 can move separately.

[0063] In the third embodiment, the first screen door engaging portion 451D of the screen door engaging portion 45 is fixed to the surface of the screen door vertical frame 43 on the outside of the room of the inner screen door 410. The shape of the first screen door engaging portion 451D is the same as the shape of the second screen door engaging portion 452 shown in FIG. 4. The first screen door engaging portion 451D is fixed to a portion of the screen door vertical frame 43 where the engaged portion 66 is not fixed. The arrangement of the second screen door engaging portion 452D is the same as that of the first embodiment. That is, the second screen door engaging portion 452D is fixed to a position where it can engage with the first screen door engaging portion 451D on the surface of the screen door vertical frame 43 on the outside of the view direction of the outer screen door 420. Therefore, even in the third embodiment, the inner screen door 410 and the outer screen door 420 can move in conjunction with each other.

[0064] According to the third embodiment, the movements of the outer screen 330 and the inner screen door 410 can be linked by mechanical engagement between the stopper member 65 and the engaged portion 66, so that even if the screen or screen door 4 becomes larger and therefore heavier, the movements of the outer screen 330 and the inner screen door 410 can be linked more reliably.

[0065] In the first embodiment, the screen door engaging portion 45 is described as a short part attached to one side and the other side of the screen door vertical frame 43 in the vertical direction. However, the location of placement is not limited to one side and the other side in the vertical direction. For example, it may be placed in one place in the vertical center. Furthermore, the screen door engaging portion may have a long shape that is placed from one side to the other side in the vertical direction of the screen door vertical frame 43. By placing the screen door engaging portion continuously in the vertical direction, it is no longer necessary to strictly match the placement of the outer screen door 420 side and the inner screen door 410 side, improving workability and operability.

[0066] In the first to third embodiments, the mohair 46 is attached to the outer screen door 420 and extends in the front direction toward the inner screen door 410. However, it may also be attached to the inner screen door 410 and extend in the front direction toward the outer screen door 420.

[0067] In the above embodiment, the sliding window 100 is described as having six shoji screens 3 and four screen doors 4. There is no limitation on the number of shoji screens 3 and screen doors 4. For example, the sliding window may have three shoji screens 3, or may have more than three. [Explanation of symbols]
