DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] An embodiment of a shoji screen will be described with reference to Figs. 1 to 3. As shown in FIG. 1, the shoji screen 10 has a framework 11. The framework 11 has a lower crosspiece 12, an upper crosspiece 13, an upper middle crosspiece 14A, a lower middle crosspiece 14B, a left vertical crosspiece 15A, and a right vertical crosspiece 15B. These are made of wood. The lower crosspiece 12, the upper crosspiece 13, the upper middle crosspiece 14A, and the lower middle crosspiece 14B extend in the left-right direction. The left vertical crosspiece 15A and the right vertical crosspiece 15B extend in the up-down direction. The lower crosspiece 12 connects the lower end of the left vertical crosspiece 15A to the lower end of the right vertical crosspiece 15B. The upper crosspiece 13 connects the upper end of the left vertical crosspiece 15A to the upper end of the right vertical crosspiece 15B. The upper center rail 14A and the lower center rail 14B are located between the lower rail 12 and the upper rail 13, and connect the left side vertical rail 15A and the right side vertical rail 15B.

[0009] The frame 11 has a left side upright 16A and a right side upright 16B. These are made of wood. The left side upright 16A extends vertically to the left of the center in the horizontal direction. The right side upright 16B extends vertically to the right of the center in the horizontal direction. The left side upright 16A and the right side upright 16B are connected to the lower rail 12, the upper rail 13, and the middle rails 14A and 14B.

[0010] The shoji screen 10 has a child shoji screen 20 that can be opened and closed in the left-right direction in the area surrounded by a pair of upper and lower center bars 14A, 14B and a pair of left and right vertical bars 15A, 15B. Fig. 1 shows the shoji screen 10 with the child shoji screen 20 in a closed state. The child shoji screen 20 has shoji paper 21 attached thereto, as indicated by dots. The child shoji screen 20 is formed so that the room interior of the left vertical bar 16A and the right vertical bar 16B can be opened and closed.

[0011] The framework 11 has central uprights 16C. The central uprights 16C extend vertically through the center in the left-right direction. One of the central uprights 16C connects the upper rail 13 and the upper center rail 14A. One of the central uprights 16C connects the lower rail 12 and the lower center rail 14B.

[0012] The framework 11 has horizontal members 18 extending in the left-right direction at various locations. Between the lower rail 12 and the lower center rail 14B, horizontal members 18 that connect the left vertical rail 15A and the right vertical rail 15B are arranged in parallel in the vertical direction. These horizontal members 18 are connected to each of the left vertical rail 16A, the right vertical rail 16B, and the center vertical rail 16C.

[0013] Between the lower center rail 14B and the upper center rail 14A, a cross bar 18 that connects the left side vertical rail 15A and the left side vertical rail 16A is arranged in parallel in the vertical direction. Also, a cross bar 18 that connects the right side vertical rail 15B and the right side vertical rail 16B is arranged in parallel in the vertical direction.

[0014] Between the upper middle rail 14A and the upper rail 13, a cross bar 18 that connects the left side vertical rail 15A and the right side vertical rail 15B is arranged in parallel in the vertical direction. The cross bar 18 is connected to each of the left side vertical rail 16A, the right side vertical rail 16B, and the center vertical rail 16C.

[0015] As shown in FIG. 2, the shoji screen 10 is provided with a daylight plate 25 at each opening formed by the lower crosspiece 12, the upper crosspiece 13, the pair of upper and lower middle crosspieces 14A, 14B, the pair of left and right vertical crosspieces 15A, 15B, and the vertical crosspieces 16A, 16B, 16C. For example, the daylight plate 25 is a glass plate. Also, for example, the daylight plate 25 is a resin plate such as an acrylic resin. The daylight plate 25 may be a transparent plate or a translucent plate. The horizontal bar 18 described above is disposed on the indoor side of the daylight plate 25. The daylight plate 25 has an outer edge engaged with a groove formed in a member forming each opening. Among these grooves, the grooves that open downward in the upper crosspiece 13, the upper middle crosspiece 14A, and the lower middle crosspiece 14B are formed at the right end or left end to a depth that allows the daylight plate 25 to be attached and detached.

[0016] (Tateko) The structures of the uprights 16A, 16B, and 16C will be described below. Note that, hereinafter, when there is no need to distinguish between the uprights 16A, 16B, and 16C, they will simply be referred to as uprights 16.

[0017] As shown in FIG. 3, the upright member 16 is formed by a force member 30 and a push edge 31 . The force element 30 is a member that has an indoor end surface 30a and an outdoor end surface 30b and extends in the vertical direction. The force element 30 has a cross section that is wider the closer it is to the edge 31, that is, the outdoor end surface 30b that holds the daylight panel 25 is wider than the indoor end surface 30a. In this embodiment, the force element 30 has an isosceles trapezoidal cross section.

[0018] The edge 31 is a member that extends vertically along the force element 30 on the outdoor side of the force element 30. The edge 31 is connected to the force element 30 by brass nails (not shown) that are driven into various places from the outdoor side. By connecting the edge 31 to the force element 30, a groove is formed in the upright 16 into which the outer edge of the daylight plate 25 engages.

[0019] The pressing edge 31 has a first restricting portion 33 and a second restricting portion 34 and is formed to have a substantially T-shaped cross section. The first restricting portion 33 abuts against the outdoor end surface 30b of the force element 30 and is formed to be narrower than the outdoor end surface 30b. The first restricting portion 33 restricts movement of the daylight plate 25 in the left-right direction. The second restricting portion 34 is formed to have a width approximately equal to the outdoor end surface 30b of the force element 30. The second restricting portion 34 restricts movement of the daylight plate 25 to the outdoor side.

[0020] In addition, the first restricting portion 33 contacts the force element 30 in the center in the left-right direction in the central upright element 16C. The first restricting portion 33 is formed so as to contact the force element 30 in the center and center left area in the left-right direction in the left-right direction in the left-right direction in the left-right direction in the left-right direction in the left-right direction in the right-right direction in the right-right direction in the right-right direction in the left-right direction in the right-right direction in the left-right direction in the right-left ... left-right direction in the right-left direction in the left-right direction in the right-left direction in the left-right direction in the right-left direction in the left-right direction in the left-right direction in the right-left direction in the left-right direction in the right-left direction in the left-right direction in the right-left direction in the left-right direction in the left-right direction in the right-left direction in the left-right direction in the right-left direction in

[0021] In addition, in the portion between the lower middle rail 14B and the upper middle rail 14A, the vertical bars 16A, 16B are often covered by the sliding door 20. Therefore, in that portion, the vertical bars 16A, 16B may have a rectangular cross section of the forceps 30.

[0022] (Assembling method) An example of a method for assembling a shoji screen 10 will be described. First, the lower rail 12, the upper rail 13, the pair of upper and lower middle rails 14A, 14B, the pair of left and right vertical rails 15A, 15B, the tension members 30 of the vertical rails 16A, 16B, 16C, and the horizontal members 18 are connected to each other to assemble the framework 11. Next, the deep grooves formed in each of the upper rail 13, the upper middle rail 14A, and the lower middle rail 14B are used to place the daylight board 25 so as to block each opening. Then, the pressing edge 31 is connected to the tension members 30 of each vertical rail 16A, 16B, 16C to assemble the shoji screen 10.

[0023] The operation and effects of this embodiment will be described. (1) The tension member 30 is formed with a cross section that becomes wider from the indoor end face 30a toward the outdoor end face 30b. When the shoji screen 10 is viewed from inside the room, the indoor end face 30a, which is not directly exposed to light, is strongly impressed. In other words, the narrow indoor end face 30a gives a strong impression, preserving the delicate appearance of a shoji screen, while the wide outdoor end face 30b forms a groove, which allows the daylight plate 25 to be securely held in place.

[0024] (2) The cross section of the forceps 30 is an isosceles trapezoid. This makes the forceps 30 wider on both sides of the end surface 30a on the interior side, which prevents the impression of the shoji screen 10 from changing depending on the viewing direction from the interior side.

[0025] (3) In the central upright 16C, the first restricting portion 33 of the pressing edge 31 abuts against the force element 30 in the central region in the left-right direction. In the left upright 16A, the first restricting portion 33 abuts against the force element 30 in the central and left-center regions in the left-right direction. In the right upright 16B, the first restricting portion 33 abuts against the force element 30 in the central and right-center regions in the left-right direction. With this configuration, the daylight plate 25 that engages with the central upright 16C and the left upright 16A, and the daylight plate 25 that engages with the central upright 16C and the right upright 16B can be more reliably held. That is, the daylight plate whose left edge and right edge both engage with the grooves of the uprights can be more reliably held.

[0026] (4) The shoji screen 10 includes a child shoji screen 20 whose opening is closed by shoji paper 21. This can improve the design of the shoji screen 10. This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0027] The frame 11 is not limited to being made of wood, but may be made of light metal or the like. The shoji screen 10 does not have to be equipped with a child shoji screen 20.

[0028] In the left and right upright members 16A, 16B, the pressing edge 31 may abut against the force element 30 at a central position in the left-right direction. In the upright member 16, the force member 30 is disposed on the indoor side, and the ridge 31 is disposed on the outdoor side. However, the upright member 16 may have a configuration in which the force member 30 is disposed on the outdoor side, and the ridge 31 is disposed on the indoor side.

[0029] The force element 30 has a cross section in the shape of an isosceles trapezoid. However, the force element 30 may have a cross section in a shape that is wider the closer to the pressing edge 31, and may have, for example, a cross section in the shape of a non-isosceles trapezoid or a cross section in the shape of a triangle.

[0030] The technical ideas that can be understood from the above-described embodiment and modified examples will be described. (Appendix 1) The ridge is A first restricting portion is provided that restricts movement of the light collecting plate in the left-right direction by contacting the force element, The framework comprises: a central standup element located at the center in the left-right direction, a left standup element located to the left of the central standup element, and a right standup element located to the right of the central standup element, The first restricting portion is The central upright member abuts against the force element at the center in the left-right direction, The left upright element abuts against the force element in the center and left-center areas in the left-right direction, The right upright element abuts against the force element in the center and right-center areas in the left-right direction.

[0031] (Appendix 2) The framework has a pair of upper and lower middle rails between a lower rail and an upper rail, the pair of left and right vertical rails being connected to each other, The shoji screen is provided with a child shoji screen that is supported by the pair of upper and lower middle bars and can be opened and closed in the left-right direction in an area surrounded by the pair of left and right vertical bars and the pair of upper and lower middle bars.
