The lower ends of the vertical frames 16, 17 and the lower end of the mullion 18 are connected to the lower frame 12.

[0012] When closed, the outdoor-side shoji screen 2A and the indoor-side shoji screen 2B are disposed 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-side shoji screen 2A and the indoor-side shoji screen 2B are slidable toward the side glass panel 81. As shown in FIG. 4, when open, the outdoor-side shoji screen 2A and the indoor-side shoji screen 2B are disposed 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 top 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 top 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 is formed up to the height of the shoji screen 2, and it is not necessary that the first upper glass panel 82 and the second upper glass panel 83 are provided.

[0014] The shoji screen 2 has a frame body 20 and a glass panel 29. The frame body 20 has an upper frame 21 (see FIG. 2), a lower frame 22 (see FIG. 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 up-down 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 20 which is formed in a four-sided frame shape. The glass panel 29 is made of tempered glass. The glass panel 29 corresponds to the panel material in the claims. As the panel material, ordinary plate glass, a resin plate material, etc. can be used.

[0017] As shown in Fig. 2, a door roller 21a provided on an upper frame 21 is supported so as to be slidable in the width direction on a rail 13a attached to intermediate frames 13 and 14. The shoji screen 2 is a top-hung single-sliding door.

[0018] The outdoor-side door 2A and the indoor-side door 2B are opened and closed in conjunction with each other by an interlocking mechanism 27, so that the outdoor-side door 2A follows the movement of the indoor-side door 2B. The interlocking mechanism 27 has an interlocking member 27A attached to the bottom frame 22 of the outdoor-side door 2A. A back plate 272 is attached to the inside of the bottom frame 22 by a screw 271. The back plate 272 is attached to the back plate 272 by a screw 273 from the recess of the interlocking member 27A that is recessed from the indoor side. As shown in FIG. 3, a cushioning material 275 is provided on the surface of the interlocking member 27A facing the indoor-side door 2B. When the indoor-side door 2B moves in the opening direction, the vertical frame 23 on the end side of the indoor-side door 2B hits the cushioning material 275 of the outdoor-side door 2A. As a result, the outdoor-side door 2A is pushed by the indoor-side door 2B, and the outdoor-side door 2A also opens. A door stopper member 28 having the same structure as the interlocking member 27A is attached to the bottom frame 12 of the door pocket portion. As shown in Fig. 4, when the vertical frame 23 on the door end side of the outdoor side shoji 2A hits the cushioning material 275 of the door stopper member 28, the movement of the outdoor side shoji 2A and the indoor side shoji 2B in the opening direction is restricted.

[0019] As shown in Figures 1 and 3, in the indoor side shoji 2B, a vertical frame with a handle 24 is provided in place of the vertical frame 23A located on the door end side of the pair of vertical frames 23, 23 in the vertical direction midway. In the indoor side shoji 2B, the vertical frame 23 may not be provided on the door end side of the pair of vertical frames 23, 23, and the vertical frame 24 with a handle may be provided over approximately the entire length in the vertical direction. The vertical frame 24 with a handle corresponds to the vertical member in the claims.

[0020] As shown in Fig. 5, the handle-equipped vertical frame 24 has a vertical frame portion 25 and handle portions 26, 26 provided on both the indoor and outdoor sides. The vertical frame portion 25 and the handle portions 26, 26 are integrally formed. The vertical frame portion 25 and the handle portion 26 are integrally formed from an aluminum profile.

[0021] The vertical frame portion 25 has a base portion 251, recessed wall portions 252, 252 on both indoor and outdoor sides, and extended wall portions 253, 253 on both indoor and outdoor sides. The base portion 251 is disposed along the end surface 29a of the glass panel 29. The base portion 251 is formed in a flat plate shape. The plate surface of the base portion 251 faces in the width direction. The recessed wall portion 252 is connected to both ends of the base portion 251 in the indoor / outdoor direction. The inner surface in the width direction of the recessed wall portion 252 is shaped to be recessed outward in the width direction. The extended wall portion 253 extends inward in the width direction from the outer end of the recessed wall portion 252 in the indoor / outdoor direction.

[0022] A glass groove 31 is formed on the inner edges of the substrate portion 251, the recess wall portion 252, and the extension wall portion 253, that is, on surfaces facing inward in the width direction. The glass groove 31 corresponds to a panel groove in the claims.

[0023] An end face 29a of the glass panel 29 is disposed at the center of the glass groove 31 in the indoor / outdoor direction. A pressing edge locking piece 255 that protrudes outward in the indoor / outdoor direction is provided at both ends of the outer side of the base plate portion 251 in the indoor / outdoor direction. A pressing edge 41 is provided along the surface facing inward in the width direction of the recess wall portion 252 and the extension wall portion 253. The pressing edge 41 is formed in a ring shape in a horizontal cross section. A surface 41b facing inward in the indoor / outdoor direction of the pressing edge 41 abuts against the seal material 30. The locking piece 41a of the pressing edge 41 is locked to the pressing edge locking piece 255. The pressing edge 41 supports the glass panel 29 via the seal material 30. The vertical frame portion 25 and the pressing edge 41 correspond to the panel holding portion in the claims. The vertical frame portion 25 corresponds to at least a part of the panel holding portion in the claims.

[0024] Handle portion 26 protrudes outward in the indoor / outdoor direction from the inner end in the width direction of extending wall portion 253. Handle portion 26 is formed in a plate shape. The plate surface of handle portion 26 faces the width direction. A user can grip handle portion 26 in the width direction. A protrusion 261 that protrudes outward in the width direction is provided at the outer end in the indoor / outdoor direction of handle portion 26.

[0025] A surface 26b of the handle portion 26 facing outward in the width direction is set back inward in the width direction relative to a surface 25a of the vertical frame portion 25 facing outward in the width direction.

[0026] It is preferable that width W1 from surface 25a of vertical frame portion 25 to surface 26a facing inward in the width direction of handle portion 26 is 10 mm to 40 mm.

[0027] A cushioning recess 257 recessed inward in the width direction is formed on the surface 25a of the vertical frame portion 25. A protrusion 37b provided on the mounting portion 32a of the cushioning material 32 is engaged with the opening edge of the cushioning recess 257. The cushioning material 32 protrudes outward in the width direction beyond the surface 25a of the vertical frame portion 25.

[0028] As shown in Fig. 4, when the outdoor-side screen 2A and the indoor-side screen 2B are open, the distance from the cushioning material 32 of the vertical frame with handle 24 to the cushioning material 17a provided on the vertical frame 17 is defined as the effective opening width W11. Since the width W1 of the vertical frame portion 25 is set short at 10 mm to 40 mm, it is possible to ensure a wide effective opening width W11.

[0029] In the fitting 100 configured in this manner, the handle portion 26 of the vertical frame with handle 24 is formed integrally with the vertical frame portion 25. Since there is no need to provide reinforcement to the vertical frame for mounting a handle, the vertical frame with handle 24 can be configured compactly, ensuring a wide effective opening width W11 when the shoji screen 2 is opened. By configuring the vertical frame with handle 24 compactly, the design is improved.

[0030] The handle portion 26 protrudes from the vertical frame portion 25 to both the outdoor side and the indoor side. By making the handle portion 26 compact on both the indoor and outdoor sides, the design on both the indoor and outdoor sides is improved. Users can hold the handle portion 26 from both the indoor and outdoor sides to open and close the shoji screen 2.

[0031] By forming the handle portion 26 integrally with the vertical frame portion 25 rather than forming the handle and the vertical frame separately, the number of parts can be reduced. The installation work for attaching the handle to the vertical frame can also be reduced.

[0032] If the width of the vertical frame is short, the strength with which the glass panel is held will be low; however, in the building fixture 100, the glass panel 29 is made of reinforced glass that is resistant to breaking even when bent, and therefore damage to the glass panel 29 can be suppressed.

[0033] Since the width W1 from the surface 25a of the vertical frame 25 of the handle portion 24 to the surface 26a of the handle portion 26 is 10 mm to 40 mm, the vertical frame 24 with handle has a slim design, further improving the aesthetic appeal.

[0034] Second Embodiment The fitting according to the second embodiment will be described mainly with reference to Figures 6 to 8. In the embodiments and modifications described below, the configurations corresponding to the embodiments described above may be given the same reference numerals and descriptions thereof may be omitted.

The fitting 100A comprises a frame 1A and two shoji screens 2C, 2C. In the frame 1A, two mullions 18 are arranged between a vertical frame 16 and a vertical frame 17.

[0036] The configuration of the shoji 2C is the same as that of the indoor shoji 2B of the fitting 100. The right-side shoji 2C seen from the indoor side is configured by flipping the left-side shoji C in the width direction. When the two shoji 2C are closed, the vertical frames 24 with handles are arranged with their faces 25a facing each other.

[0037] In the fitting 100A configured in this manner, the handle portion 26 of the vertical frame with handle 24 is formed integrally with the vertical frame portion 25. Since there is no need to provide reinforcement to the vertical frame to attach a handle, the vertical frame with handle 24 can be configured compactly, and a wide effective opening width W11 can be ensured when the shoji screen 2 is opened. By configuring the vertical frame with handle 24 compactly, the design is improved.

[0038] Surface 26b of handle portion 26 facing outward in the width direction is set back inward in the width direction from surface 25a of vertical frame portion 25. When shoji screens 2C are closed, a space S (see FIG. 8) is formed between handle portions 26 of adjacent shoji screens 2C, so that a user can reach into space S and grasp handle portion 26 to open shoji screens 2C.

[0039] Third embodiment The fitting according to the third embodiment will be described mainly with reference to FIG. 9. As shown in FIG. 9, the vertical frame 25B is configured as a separate body from the handle portion 26B. The handle portion 26B is formed integrally with the ridge portion 41B.

[0061] In the fitting constructed in this manner, the handle portion 26E of the vertical frame with handle 24E is formed integrally with the vertical frame portion 25. Since there is no need to provide reinforcement to the vertical frame to attach a handle, the vertical frame with handle 24E can be constructed compactly, and a wide effective opening width W11 can be ensured when the shoji screen 2 is opened. The compact construction of the vertical frame with handle 24E improves the design.

[0062] If the shoji screen 2 is to be opened and closed manually only from the indoor side, the handle portion 26E can be provided only on the indoor side.

[0063] The handle portion 26E is provided with an extension 267 that protrudes inward in the width direction. A user can grip the extension 267 to open or close the container.

The vertical frame portion 25G and the pressing edge portion 41G correspond to the panel holding portion in the claims.

[0075] A glass groove 31G is formed on the surfaces facing inward in the width direction, which are the inner edges of the substrate portion 251, the connecting wall portion 500, and the abutting wall portion 411. The glass groove 31G is formed by a recess surrounded by the abutting walls 411, 411, the connecting walls 500, 500, and the substrate portion 251. The glass groove 31G corresponds to a panel groove in the claims.

[0076] A protrusion 502 is formed inside the hollow portion 501, protruding inward in the indoor / outdoor direction from the extending wall portion 253. The protrusion 502 extends in the indoor / outdoor direction. The protrusion 502 serves to position the upper frame 21 and the lower frame 22 when they are connected to the vertical frame 23. When positioning the upper frame 21 with respect to the vertical frame 23, the upper frame 21 can be positioned in the width direction by bringing the upper frame 21 into contact with the protrusion 502. When positioning the lower frame 22 with respect to the vertical frame 23, the lower frame 22 can be positioned in the width direction by bringing the lower frame 22 into contact with the protrusion 502.

[0077] The handle portion 26G protrudes outward in the indoor / outdoor direction from the inner end of the extending wall portion 253 in the width direction. The handle portion 26G is formed in a plate shape. The plate surface of the handle portion 26G faces the width direction. A user can grip the handle portion 26G in the width direction. The inner surface 26a of the handle portion 26G facing inward in the width direction is formed as a smooth surface. The outer surface 26b of the handle portion 26G facing outward in the width direction is formed as a smooth surface. The inner surface 26a of the handle portion 26G and the surface of the pressing edge portion 41G facing inward in the width direction are formed to be flush with each other.

[0078] An outer surface 26b of the handle portion 26 facing outward in the width direction is set back inward in the width direction relative to an outer surface 25a of the vertical frame portion 25G facing outward in the width direction.

[0079] A width W1 from an outer surface 25a of the vertical frame portion 25G to an inner surface 26a of the handle portion 26G facing inward in the width direction is preferably 10 mm to 40 mm.

[0080] A cushioning recess 257 recessed inward in the width direction is formed on the outer surface 25a of the vertical frame portion 25G. A protrusion 37b provided on the mounting portion 32a of the cushioning material 32 is engaged with the opening edge of the cushioning recess 257. The cushioning material 32 protrudes outward in the width direction beyond the outer surface 25a of the vertical frame portion 25G.

[0081] As shown in Figs. 16 and 17, a cover member 505 is attached to the lower end of the handle portion 26G. The cover member 505 has a shape that covers the side and bottom surfaces of the handle portion 26G. The cover member 505 is fixed to the handle portion 26G with screws. The cover member 505 is formed of a resin such as plastic. The cover member 505 is formed to a size that covers, for example, about 2 cm from the lower end of the handle portion 26G. The cover member may be shaped to cover not only the lower end of the handle portion 26G but also the lower ends of the vertical frame portion 25G and the pressing edge portion 41G.

[0082] As shown in Fig. 4, when the outdoor-side screen 2A and the indoor-side screen 2B are open, the distance from the cushioning material 32 of the glass-holding member with handle 24G to the cushioning material 17a provided on the vertical frame 17 is defined as the effective opening width W11. Since the width W1 of the vertical frame portion 25G is set short at 10 mm to 40 mm, a wide effective opening width W11 can be ensured.

[0083] The handle portion 26G of the glass-holding member with handle 24G is formed integrally with the vertical frame portion 25G. Since there is no need to provide reinforcement to the vertical frame to attach the handle, the glass-holding member with handle 24G can be configured compactly, and the effective opening width W11 when the shoji screen 2 is opened can be secured widely. The design is improved by configuring the glass-holding member with handle 24G compactly.

[0084] A connecting wall 500 is provided between the widthwise outer end of the abutting wall 411 of the pressing edge 41G and the indoor / outdoor end of the base plate 251 of the vertical frame 25G, connecting them together. The provision of the connecting wall 500 can improve the strength of the glass holding member with handle 24G.

[0085] The handle portion 26G protrudes from the vertical frame portion 25G to both the outdoor side and the indoor side. The inner surface 26a and the outer surface 26b of the handle portion 26G are formed to be smooth without any irregularities. By making the handle portion 26G compact and simple on both the indoor and outdoor sides, the design on both the indoor and outdoor sides is improved. Users can hold the handle portion 26G from both the indoor and outdoor sides to open and close the shoji screen 2.

[0086] By forming the handle 26G integrally with the vertical frame 25G, rather than making the handle and the vertical frame separate, the number of parts can be reduced. The assembly work required to attach the handle to the vertical frame can be reduced. Since there is no need to provide reinforcement to the vertical frame or the edge to attach the handle, the glass retaining member with handle 24G can be made compact, and a wide effective opening width W11 can be ensured when the shoji screen 2 is opened.

[0087] If the width of the vertical frame is short, the strength with which the glass panel is held will be low. However, since the glass panel 29 is made of reinforced glass that is resistant to breaking even when bent, damage to the glass panel 29 can be suppressed.

[0088] The width W1 from the outer surface 25a of the vertical frame portion 25G of the glass-holding member with handle 24G to the inner surface 26a of the handle portion 26G is 10 mm to 40 mm, so that the glass-holding member with handle 24G has a slim design, further improving the aesthetic appeal.

[0089] A protrusion 502 is formed inside the hollow portion 501 formed in the glass holding member with handle 24G, so that positioning can be performed reliably and easily when connecting the upper frame 21 and the lower frame 22 to the vertical frame 23.

[0090] A cover member 505 is attached to the lower end of the handle portion 26G, so that the end of the member can be reliably protected even if the glass holding member with handle 24G is manufactured by extrusion molding of aluminum material.

[0091] Although the preferred embodiments of the present disclosure have been described above with reference to the accompanying drawings, it goes without saying that the present disclosure is not limited to the examples. The shapes and combinations of the components shown in the above examples are merely examples, and various modifications can be made based on design requirements, etc., without departing from the spirit of the present disclosure.
