In the following description, the direction that connects the outdoor side (the +Y side shown in Figure 2, etc.) and the indoor side (the -Y side shown in Figure 2, etc.) along the horizontal direction is referred to as the indoor-outdoor direction (direction of arrow Y in the figure). The direction that is perpendicular to the indoor-outdoor direction and along the horizontal direction is referred to as the width direction (direction of arrow X in the figure). On one side of the width direction, the direction in which the sliding door 2 closes is referred to as the closing direction (the +X side shown in the figure). On the other side of the width direction, the direction in which the sliding door 2 opens is referred to as the opening direction (the -X side shown in the figure). The direction that is perpendicular to the indoor-outdoor direction and the width direction is referred to as the up-down direction (direction of arrow Z in the figure). In each component, the side that moves away from the center in the indoor-outdoor direction and the width direction may be referred to as the outside, and the side that moves towards the center may be referred to as the inside.

[0009] As shown in Figure 1, the sliding door 100 is a door that is opened and closed by manually moving the outdoor side sash 2A and the indoor side sash 2B in the width direction. The sliding door 100 comprises a frame 1, the outdoor side sash 2A and the indoor side sash 2B, an opening interlocking mechanism 27 (see Figure 2), a first closing interlocking mechanism 30 (see Figure 3), and a second closing interlocking mechanism 40 (see Figure 2).

The vertical middle of the vertical frames 16, 17 and the vertical middle of the mullions 18 are connected to the intermediate frames 13, 14. The lower ends of the vertical frames 16, 17 and the lower ends of the mullions 18 are connected to the lower frame 12.

[0012] The outdoor sash 2A and the indoor sash 2B, when closed, are positioned in an opening formed by the bottom frame 12, intermediate frame 14, vertical frame 17, and mullion 18. A side glass panel 81 is provided in the space formed by the bottom frame 12, intermediate frame 13, vertical frame 16, and mullion 18. The outdoor sash 2A and the indoor sash 2B are slidable toward the side glass panel 81. As shown in Figure 4, the outdoor sash 2A and the indoor sash 2B, when open, are positioned on the indoor side of the side glass panel 81. A wall may be provided in the space formed by the bottom frame 12, intermediate frame 13, vertical frame 16, and mullion 18.

[0013] As shown in Figure 1, a first upper glass panel 82 is provided in the space formed by the upper frame 11, the intermediate frame 13, the upper part of the vertical frame 16, and the upper part of the mullion 18. A second upper glass panel 83 is provided in the space formed by the upper frame 11, the intermediate frame 14, the upper part of the vertical frame 17, and the upper part of the mullion 18. The frame body 1 is formed up to the height of the shoji screen 2, and the first upper glass panel 82 and the second upper glass panel 83 may not be provided.

[0014] The shoji screen 2 comprises a frame 20 and a glass panel 29. The frame 20 comprises an upper frame 21 (see Figure 2), a lower frame 22 (see Figure 2), and a pair of vertical frames 23, 23.

[0015] The upper frame 21 and the lower frame 22 extend in the width direction. The vertical frame 23 extends in the vertical direction. The upper ends of the pair of vertical frames 23, 23 are connected to the upper frame 21. The lower ends of the pair of vertical frames 23, 23 are connected to the lower frame 22.

[0016] The glass panel 29 is housed inside the frame body 20 formed in a square frame shape. The glass panel 29 is formed of tempered glass, but may be ordinary plate glass, a resin plate material, or the like.

[0017] As shown in FIG. 2, the door wheel 21a provided on the upper frame 21 is supported slidably in the width direction by a rail 13a attached to the intermediate frames 13, 14. The shoji 2 is a single-slide door of the ceiling-suspended type.

[0018] As shown in FIGS. 1 and 3, in the indoor-side shoji 2B, at the vertical middle of the vertical frame 23 arranged on the door tip side among the pair of vertical frames 23, 23, a vertical frame 24 with a handle is provided instead of the vertical frame 23. In the indoor-side shoji 2B, on the door tip side among the pair of vertical frames 23, 23, instead of providing the vertical frame 23, a vertical frame 24 with a handle may be provided over substantially the entire length in the vertical direction.

[0019] As shown in FIG. 3, the vertical frame 24 with a handle has a vertical frame portion 25 and handle portions 26 provided on both the indoor and outdoor sides. The vertical frame portion 25 and the handle portions 26 are integrally formed. The vertical frame portion 25 and the handle portions 26 are integrally molded from an aluminum profile.

[0020] The opening interlocking mechanism 27 interlocks and moves the outdoor-side shoji 2A in the opening direction when the indoor-side shoji 2B moves in the opening direction.

[0021] The opening interlocking mechanism 27 has a prospective surface 23a along the indoor-outdoor direction in the vertical frame 23 of the indoor-side shoji 2B and an opening interlocking member 27A. The prospective surface 23a of the vertical frame 23 of the indoor-side shoji 2B corresponds to the fifth surface of the claim.

[0022] As shown in Figure 2, the opening interlocking member 27A is attached to the lower frame 22 of the outdoor side sash 2A. Inside the lower frame 22, a backing plate 272 is attached by screws 271. The opening interlocking member 27A is attached to the backing plate 272 by screws 273 from a recess that is recessed from the indoor side. As shown in Figure 3, a cushioning material 275 is provided on the surface of the opening interlocking member 27A that faces the indoor side sash 2B.

[0023] The lower visible surface 23a of the vertical frame 23 on the door-end side of the indoor shoji screen 2B faces the opening direction. The opposing surface 275a of the cushioning material 275 faces the visible surface 23a of the vertical frame 23. The opposing surface 275a corresponds to the sixth surface of the claim.

[0024] When the handle portion 26 is grasped and the indoor sliding door 2B is moved in the opening direction, the lower projection surface 23a of the vertical frame 23 on the tail end side of the indoor sliding door 2B comes into contact with the opposing surface 275a of the cushioning material 275 of the outdoor sliding door 2A. The outdoor sliding door 2A is pushed by the indoor sliding door 2B and also moves in the opening direction. A door stop member 28, which has the same configuration as the opening interlocking member 27A, is attached to the lower frame 12 of the door pocket portion. As shown in Figure 4, when the vertical frame 23 on the tail end side of the outdoor sliding door 2A hits the cushioning material 275 of the door stop member 28, the movement of the outdoor sliding door 2A and the indoor sliding door 2B in the opening direction is restricted.

[0025] As shown in Figure 3, the first closing interlocking mechanism 30 moves the outdoor side sash 2A in the closing direction in conjunction with the movement of the indoor side sash 2B in the closing direction. The first closing interlocking mechanism 30 includes a first interlocking member 31B provided on the vertical frame 23 of the indoor side sash 2B and a second interlocking member 31A provided on the vertical frame 23 of the outdoor side sash 2A.

[0026] The first interlocking member 31B and the second interlocking member 31A are composed of the same elongated interlocking member 31. The orientation of the elongated interlocking member 31 is reversed in the width direction and in the indoor / outdoor direction between the first interlocking member 31B and the second interlocking member 31A. The elongated interlocking member 31 is made of resin.

[0027] The vertical frame 23 of the outdoor-side shoji screen 2A has a locking recess 231 formed on the surface facing the indoor side, which is recessed to the outdoor side. The locking recess 231 is formed along substantially the entire vertical length of the vertical frame 23 of the outdoor-side shoji screen 2A. The locking recess 231 opens to the indoor side. The widthwise length of the opening side 231a of the locking recess 231 is shorter than the widthwise length of the back side 231b of the locking recess 231. The vertical frame 23 of the outdoor-side shoji screen 2A and the vertical frame 23 of the indoor-side shoji screen 2B face each other in the indoor-outdoor direction. The vertical frame 23 of the indoor-side shoji screen 2B has a locking recess 231 formed on the surface facing the outdoor side. The locking recess 231 corresponds to the groove of the claim.

[0028] The locking recess 231 formed in the vertical frame 23 of the indoor side shoji screen 2B is configured by reversing the locking recess 231 formed in the vertical frame 23 of the outdoor side shoji screen 2A in the indoor / outdoor direction, and therefore its explanation is omitted.

[0029] The elongated interlocking member 31 is positioned on the portion of the vertical frame 23 other than the lower part in the vertical direction. The elongated interlocking member 31 has a locking portion 311, an extension portion 312, a visible wall portion 313, an interlocking wall portion 314, and an inclined wall portion 315.

[0030] The following describes the first interlocking member 31B attached to the indoor side of the sliding door 2B. The second interlocking member 31A is configured by reversing the first interlocking member 31B in the width direction and the indoor / outdoor direction, and will be omitted from description except for the differences. The locking portion 311 is located on the back side 231b of the locking recess 231 of the vertical frame 23. The extension portion 312 extends from the locking portion 311 to the outdoor side. The length of the locking portion 311 in the width direction is longer than the length of the extension portion 312 in the width direction. As a result, the locking portion 311 is locked into the locking recess 231 of the vertical frame 23.

[0031] The visible wall portion 313 is positioned along the opening side 231a of the locking recess 231 of the vertical frame 23. The visible wall portion 313 is positioned along the surface of the vertical frame 23 facing the outside. The widthwise length of the visible wall portion 313 is longer than the widthwise length of the extension portion 312.

[0032] The interlocking wall portion 314 extends from the inner end of the shoji screen 2 in the width direction of the visible wall portion 313 toward the outside. In the interlocking wall portion 314 of the first interlocking member 31B, the surface 314a facing the closing direction is aligned with the indoor / outdoor direction. In the interlocking wall portion 314 of the second interlocking member 31A, the surface 314b is aligned with the indoor / outdoor direction. The surface 314b of the second interlocking member 31A faces the surface 314a of the first interlocking member 31B. The surface 314a of the first interlocking member 31B corresponds to the first surface of the claim. The surface 314b of the second interlocking member 31A corresponds to the second surface of the claim.

[0033] The inclined wall section 315 extends outward from the outer end of the shoji screen 2 in the width direction of the visible wall section 313, and gradually curves inward in the width direction of the shoji screen 2 as it extends outward. The outdoor end of the inclined wall section 315 is connected to the outdoor end of the interlocking wall section 314.

[0034] In the long interlocking member 31, the tip 316 that connects the interlocking wall portion 314 and the inclined wall portion 315 is formed in a V-shape and tapers towards the end. The length of the tip 316 of the long interlocking member 31 decreases in the width direction as it faces the outdoor side.

[0035] The widthwise length A1 of the long interlocking member 31 is approximately the same as the widthwise length A2 of the vertical frame 23. Lengths A1 and A2 are approximately 5 mm to 10 mm apart.

[0036] As shown in Figure 6, a mohair 32 is attached to the lower part of the locking recess 231 of the vertical frame 23, instead of a long interlocking member 31. The mohair 32 has a base portion 321 and a pile portion 322. The base portion 321 is formed in a strip shape that extends in the vertical direction. The pile portion 322 protrudes from one side of the base portion 321 toward the opposing vertical frame 23.

[0037] The base portion 321 is fitted into the locking recess 231 of the vertical frame 23. By applying adhesive to the other side of the base portion 321, it can be fixed within the locking recess 231. By bending the walls on both sides of the opening side 231a of the vertical frame 23 toward the base portion 321, the base portion 321 can be fixed within the locking recess 231. The locking recess 231 is a conventional groove for attaching the mohair 32.

[0038] As shown in Figure 4, when the handle portion 26 is grasped and the indoor sash 2B is moved a predetermined distance in the closing direction, the surface 314a of the first interlocking member 31B provided on the indoor sash 2B comes into contact with the surface 314b of the second interlocking member 31A provided on the outdoor sash 2A, as shown in Figure 5. The outdoor sash 2A is pushed by the indoor sash 2B and the outdoor sash 2A also moves in the closing direction. Both the outdoor sash 2A and the indoor sash 2B are closed.

[0039] The second closing interlocking mechanism 40 shown in Figure 2 moves the outdoor sliding door 2A in the closing direction in conjunction with the movement of the indoor sliding door 2B in the closing direction. The second closing interlocking mechanism 40 includes a third interlocking member 41B provided on the upper frame 21 of the indoor sliding door 2B and a fourth interlocking member 41A provided on the upper frame 21 of the outdoor sliding door 2A.

[0040] The third interlocking member 41B and the fourth interlocking member 41A are composed of the same upper interlocking member 41. The orientation in which the upper interlocking member 41 is positioned is reversed in the width direction and in the indoor / outdoor direction between the third interlocking member 41B and the fourth interlocking member 41A. The upper interlocking member 41 is made of metal.

[0041] The third interlocking member 41B will be described below. The fourth interlocking member 41A is configured by reversing the third interlocking member 41B in the width direction and in the indoor / outdoor direction, and will be described in part except for the differences. As shown in Figure 8, the upper interlocking member 41 is fixed to the upper surface 21u of the upper frame 21. As shown in Figure 9, the upper interlocking member 41 has a fixing plate portion 411, a first upright plate portion 412, a second upright plate portion 413, and a cushioning material 414.

[0042] As shown in Figure 8, the fixing plate portion 411 is positioned on the upper surface 21u of the upper frame 21. An extension portion 411c extending outwards is provided at one end of the fixing plate portion 411 in the width direction. A screw 411a is inserted through the screw hole 411b (see Figure 9) of the fixing plate portion 411 and screwed to the upper surface 21u of the upper frame 21.

[0043] The first upright plate portion 412 extends upward from the outdoor end of the extension portion 411c of the fixed plate portion 411. The second upright plate portion 413 extends upward from the other end in the width direction of the extension portion 411c of the fixed plate portion 411. The other end in the width direction of the first upright plate portion 412 and the outdoor end of the second upright plate portion 413 are joined together.

[0044] The cushioning material 414 is fixed to the other side in the width direction of the second upright plate portion 413 by a screw 414c.

[0045] In the cushioning material 414 of the third interlocking member 41B, the surface 414a facing the closing direction is aligned with the indoor / outdoor direction. In the cushioning material 414 of the fourth interlocking member 41A, the surface 414b is aligned with the indoor / outdoor direction. The surface 414b of the fourth interlocking member 41A faces the surface 414a of the third interlocking member 41B. The surface 414a of the third interlocking member 41B corresponds to the third surface of the claim. The surface 414b of the fourth interlocking member 41A corresponds to the fourth surface of the claim.

[0046] As shown in Figure 4, when the handle portion 26 is grasped and the indoor sash 2B is moved in the closing direction, the surface 414a of the third interlocking member 41B provided on the indoor sash 2B comes into contact with the surface 414b of the fourth interlocking member 41A provided on the outdoor sash 2A. The outdoor sash 2A is pushed by the indoor sash 2B and the outdoor sash 2A also moves in the closing direction. Both the outdoor sash 2A and the indoor sash 2B are closed.

[0047] In the sliding door 100 configured in this way, when the indoor sash 2B moves in the closing direction, the surface 314a of the first interlocking member 31B facing the closing direction and the surface 314b of the second interlocking member 31A come into contact. The surface 314b of the second interlocking member 31A is pushed in the closing direction by the surface 314a of the first interlocking member 31B, causing both the indoor sash 2B and the outdoor sash 2A to close. Since the first interlocking member 31B and the second interlocking member 31A are made of resin, they can be attached to the vertical frame 23 by fitting them in or by adhesive. Even if the width of the vertical frame 23 is short, the first interlocking member 31B and the second interlocking member 31A can be attached to the vertical frame 23.

[0048] The first interlocking member 31B and the second interlocking member 31A are constructed by reversing the same long interlocking member 31 in the width direction and the indoor / outdoor direction. This reduces the number of parts compared to constructing the first interlocking member 31B and the second interlocking member 31A from separate components.

[0049] When the shoji screens 2 are installed, they may shift in the indoor / outdoor direction, causing one shoji screen 2 to be positioned closer to the other shoji screen 2, and potentially causing the long interlocking member 31 of one shoji screen 2 to come into contact with the other shoji screen 2. Because the tip 316 of the long interlocking member 31 has a tapered shape, the contact area with the other shoji screen 2 is small. As a result, frictional resistance when opening and closing the shoji screens 2 is suppressed, allowing the shoji screens 2 to be opened and closed smoothly even when one shoji screen 2 is positioned closer to the other shoji screen 2.

[0050] The width of the long interlocking member 31 is approximately the same as the width of the vertical frame 23 of the indoor sash 2B and the width of the vertical frame 23 of the outdoor sash 2A. The long interlocking member 31 is inconspicuous, improving the appearance.

[0051] The long interlocking member 31 is also attached to the locking recess 231 of the vertical frame 23 to which the mohair 32 is attached. There is no need to newly machine the locking recess 231 for attaching the long interlocking member 31, thus reducing the amount of processing work required.

[0052] A mohair 32 is attached to the lower side of the locking recess 231, and a long interlocking member 31 is attached above the mohair 32. Even if the long interlocking member 31 is about to slip downward, it is supported by the mohair 32, thus preventing the long interlocking member 31 from slipping downward.

[0053] As the indoor sash 2B moves in the closing direction, the surface 414a of the third interlocking member 41B facing the closing direction and the surface 414b of the fourth interlocking member 41A come into contact. The surface 414b of the fourth interlocking member 41A is pushed in the closing direction by the surface 414a of the third interlocking member 41B, causing both the indoor sash 2B and the outdoor sash 2A to close. The force generated when the indoor sash 2B and the outdoor sash 2A close is borne by the first interlocking member 31B, the second interlocking member 31A, the third interlocking member 41B, and the fourth interlocking member 41A, so the force is distributed and the outdoor sash 2A can be reliably closed in conjunction with the first interlocking member 31B and the second interlocking member 31A. Since excessive force is not applied to the first interlocking member 31B and the second interlocking member 31A, damage to the first interlocking member 31B and the second interlocking member 31A is suppressed.

[0054] As the indoor sliding door 2B moves in the opening direction, the visible surface 23a of the indoor sliding door 2B and the opposing surface 275a of the opening interlocking member 27A attached to the outdoor sliding door 2A come into contact. The opposing surface 275a of the opening interlocking member 27A is pushed in the opening direction by the visible surface 23a of the indoor sliding door 2B, causing both the indoor sliding door 2B and the outdoor sliding door 2A to open.

[0055] The upper parts of the indoor sash 2B and the outdoor sash 2A are suspended from the upper frame 11 in a top-hung type system. Since no large operating force is required when opening and closing, the indoor sash 2B and the outdoor sash 2A can be reliably operated in conjunction.

[0056] Preferred embodiments of this disclosure have been described above with reference to the attached drawings, but it goes without saying that this disclosure is not limited to these examples. The shapes and combinations of the components shown in the above examples are just examples and can be modified in various ways based on design requirements, etc., without departing from the spirit of this disclosure.

[0057] In the embodiment shown above, the first interlocking member 31B and the second interlocking member 31A are formed from the same elongated interlocking member 31, but this is not limited to this. The cross-sectional shapes of the first interlocking member 31B and the second interlocking member 31A may be different, and they may be formed from different materials.

[0058] The tip 316 of the long interlocking member 31 is tapered, but is not limited to this. The other end of the long interlocking member 31 on the shoji screen 2 side may be elongated in the width direction.

[0059] The widthwise length of the long interlocking member 31 is approximately the same as, but not limited to, the widthwise length of the vertical frame 23 of the indoor sash 2B and the widthwise length of the vertical frame 23 of the outdoor sash 2A. The widthwise length of the long interlocking member 31 can be set as appropriate.

[0060] The long interlocking member 31 is attached to the locking recess 231 of the vertical frame 23 to which the mohair 32 is attached, but is not limited to this. The long interlocking member 31 may be attached to another groove in the vertical frame 23, or to the vertical frame 23 by adhesive or the like.

[0061] A mohair 32 is attached to the lower side of the locking recess 231, and a long interlocking member 31 is attached above the mohair 32, but this is not limited to this configuration. The mohair 32 does not need to be attached to the locking recess 231.
