Note that the other end of the second inclined member 24 may be extended to the square timber 20d and connected to the square timber 20d. The degree of freedom in designing the muntin 21 can be increased depending on whether or not the second inclined member 24 is extended to the square timber 20d.

The horizontal member 23 is provided, for example, on an imaginary line connecting the central part of the square timber 20b and the central part of the square timber 20d. The central portion of the square bar 20b is, for example, equal to the position that bisects the square bar 20b extending in the Y-axis direction into an upper region and a lower region. The central portion of the square timber 20d is, for example, equal to the position that bisects the square timber 20d extending in the Y-axis direction into an upper region and a lower region. Note that these positions may be, for example, positions slightly shifted in the range of several mm to several tens of mm from the relevant position.

Among the plurality of crosspieces 21a2, the crosspieces 21a2 adjacent to the square beam 20c are arranged at a fixed distance _D1 from the square beam 20c in the Y-axis direction. A generally triangular lattice design is formed by the plurality of horizontal members 21a2 in a space surrounded by the second inclined member 24, the square members 20c, and the square members 20d. This roughly triangular lattice allows the space on the back side of the composite shoji 100 to be visually recognized from the front side of the composite shoji 100, or the space on the front side of the composite shoji 100 from the back side of the composite shoji 100.

The plurality of vertical members 21b1 are provided in a space surrounded by the first inclined member 22, the square members 20b, and the horizontal member 23. The number of the plurality of vertical bars 21b1 is, for example, twelve. One end of each of the plurality of vertical members 21b1 is connected to the first inclined member 22. The vertical member 21b1 extends from the connection point as a starting point toward the horizontal member 23 in the Y-axis direction in parallel with the square beam 20b. The other end of each of the plurality of vertical members 21b1 is connected to the horizontal member 23. The plurality of vertical bars 21b1 are arranged at a certain distance _D31 from each other in the X-axis direction. Among the plurality of vertical bars 21b1, the vertical bars 21b1 adjacent to the square bar 20b are arranged at a constant distance D ₃₂ from the square bar 20b in the Y-axis direction.

A generally triangular lattice design is formed in the space surrounded by the first inclined member 22, the square members 20b, and the horizontal member 23 by the plurality of vertical members 21b1. This roughly triangular lattice allows the space on the back side of the composite shoji 100 to be visually recognized from the front side of the composite shoji 100, or the space on the front side of the composite shoji 100 from the back side of the composite shoji 100.

The plurality of vertical members 21b2 are provided in a space surrounded by the second inclined member 24, the square members 20b, and the horizontal member 23. The number of the plurality of vertical bars 21b2 is, for example, twelve. One end of each of the plurality of vertical members 21b2 is connected to the second inclined member 24.

A generally triangular lattice design is formed in the space surrounded by the second inclined member 24, the square members 20b, and the horizontal member 23 by the plurality of vertical members 21b2. This roughly triangular lattice allows the space on the back side of the composite shoji 100 to be visually recognized from the front side of the composite shoji 100, or the space on the front side of the composite shoji 100 from the back side of the composite shoji 100.

The first shoji 2-1 and the second shoji 2-2 configured in this way are provided with a frame 25, a stick 20, and a muntin 21 having the same structure, and are arranged point-symmetrically with respect to the intersection line CL. Ru. The intersection line CL is a line where the vertical center plane and the horizontal center plane intersect. The vertical center plane is a virtual plane passing through the center of the frame 1 in the Y-axis direction and parallel to the XZ plane. The center of the frame 1 in the Y-axis direction is, for example, equal to the position that bisects the opening formed inside the frame 1 into an upper region and a lower region. The lateral central plane is a virtual plane that passes through the center of the frame 1 in the X-axis direction and is parallel to YZ. The center of the frame 1 in the X-axis direction is, for example, equal to the position that bisects the opening formed inside the frame 1 into a right side area and a left side area.

In this way, the first shoji 2-1 and the second shoji 2-2 are provided with the frame 25, the attachment 20, and the kumiko 21 that have the same structure, so that they can be connected to the first shoji 2-1 and the second shoji. Compared to the case where each of 2-2 has a different shape, manufacturing is easier, and the mass production effect of the composite shoji 100 can be expected.

In addition, by arranging the first shoji 2-1 and the second shoji 2-2 point-symmetrically with respect to the intersection line CL, a virtual The line is located in the gap between two adjacent horizontal bars 21a2 of the second shoji 2-2. An imaginary line extending the horizontal bar 21a2 of the first shoji 2-1 in the X-axis direction is located in the gap between two adjacent horizontal bars 21a1 of the second shoji 2-2. In this way, in the composite shoji 100 according to the present embodiment, the positions of the laterals 21a1 and 21a2 of the first shoji 2-1 are the same as the positions of the laterals 21a1 and 21a2 of the second shoji 2-2. It's off.

Moreover, the width W ₄ of the crosspiece 21a1 or the crosspiece 21a2 in the Y-axis direction is narrower than the distance D ₄ between adjacent crosspieces 21a1 or the distance D ₄ between adjacent crosspieces 21a2.

Further, the width W ₃ of the vertical bars 21b1 or 21b2 in the X-axis direction is narrower than the distance D ₃₁ between adjacent vertical bars 21b1 or the distance D ₃₁ between adjacent vertical bars 21b2.

As shown in FIG. 3, the first shoji 2-1 is provided with a first light control section 3-1 that faces the first shoji 2-1 and is a plate-shaped light control section whose transparency can be changed. Transparent means that visible light can be transmitted. By changing the transparency, that is, changing the transmittance, you can control the shading of the landscape, or control the shading of each of the first design, second design, and third design (control the shading of the pattern). It is possible to change the appearance of the design. The plate shape has larger dimensions in the length direction and width direction (X-axis direction and Y-axis direction) than the dimension in the thickness direction (Z-axis direction), and both the front and back surfaces in the thickness direction are This includes forms in which the surface is flat and forms in which one or both of the front and back surfaces are curved. The light control unit includes light control glass, light control film, light control panel, electronic paper, light guide plate lighting, organic EL lighting, transparent liquid crystal, transparent organic EL, and the like. The light control unit may have a function as a transparent display. For example, light guide plate lighting is a panel that emits light by illuminating a transparent light guide plate from the edge or surface with light emitted from a light source such as an LED, and by changing the intensity and color tone of the light emitted from the light source, Transparency can be changed. Further, transparent liquid crystals and transparent organic EL are used for the purpose of changing the transparency of the light control unit depending on the image to be projected. In addition, these light control parts may, for example, change the entire light control part to a single color (for example, a cloudy white color), or they may be capable of projecting an image (for example, a grid pattern, landscape, illustration, or character display, which will be described later). It is also possible to change the degree of transmission of visible light. Note that examples of methods for changing the transparency of the light control section include an electrochromic method and a gaschromic method.

In an electrochromic type light control section, a light control material layer is sandwiched between film electrodes from both sides of the light control material layer, and a DC or AC voltage is applied to these film electrodes. Examples of electrochromic light control parts include those using polymer dispersed liquid crystal, and structures in which an electrolyte layer and a light control layer using tungsten oxide (WO3) are sandwiched between transparent electrodes. One has a structure in which an electrolyte layer and a magnesium-nickel alloy layer are sandwiched between transparent electrodes, and one has an indium tin oxide (ITO) layer, a tungsten oxide layer, a tantalum oxide layer, a palladium layer, and a magnesium alloy layer on a glass substrate. There are those with a laminated structure (see Non-Patent Document 1). (Non-Patent Document 1: K. Tajima et al., "Near colorless all-solid-state switchable mirror based on magnesium-titanium thin film", JOURNAL OF APPLIED PHYSICS 103, 013512, American Institute of Physics, 2008.) In a gaschromic type light control unit, the light control material film is oxidized or reduced by exposing the light control material film to, for example, oxygen or hydrogen gas. As a gas chromic type light control unit, for example, there is one using a tungsten oxide (WO3) film coated with a catalyst layer such as platinum (see Non-Patent Document 2). (Non-Patent Document 2: A. Georg et al., "Switchable windows with tungsten oxide", Vacuum 82, Elsevier Ltd., 2008, pp. 730-735). Note that the method of changing the transparency of the light control section is not limited to these methods.

The first light control unit 3-1 is provided so as to be movable in the horizontal direction integrally with the first shoji 2-1.

Further, the first light control section 3-1 may be one in which the first light control section 3-1 itself changes the transparency, or, for example, a light source provided outside the first light control section 3-1 may emit light. It may also be changed by receiving light. The same applies to the second light control section 3-2. With this configuration, the transparency can be changed using a light source provided outside the first light control section 3-1, even if the first light control section 3-1 does not have a complicated mechanism to change the transparency by itself. Therefore, the transparent area of the first light control section 3-1 can be increased, and the area where the grid pattern and the scenery overlap can be expanded.

In addition, by controlling the light intensity, it is possible to change the scene by controlling the line of sight, maintaining privacy, or creating a sense of freedom.

Although the composite shoji 100 of this embodiment includes the frame 1, the first shoji 2-1 can be directly attached to, for example, a lintel, threshold, wall, ceiling, or floor of a building without using the frame 1. A configuration may also be adopted in which a second shoji 2-2 is provided. Moreover, the first shoji 2-1 and the second shoji 2-2 used in the composite shoji 100 of this embodiment can be used not only as shoji doors but also as windows, free-standing partitions, small openings, etc. is also applicable. Furthermore, the composite shoji 100 of this embodiment can be applied to applications such as sliding doors and walls, where one of the first shoji 2-1 and second shoji 2-2 is fixed and the other is movable. It is. The same applies to the composite shoji 100A, the composite shoji 100B, and the composite shoji 100C.

A gradation is a state in which the color tone changes continuously as the position within a particular drawing changes. The same applies to the composite shoji 100A, the composite shoji 100B, and the composite shoji 100C.

In addition, the composite shoji 100 of the present embodiment has a structure in which the transparency of at least one of the first shoji 2-1 and the second shoji 2-2 is adjusted by the movement of at least one of the first shoji 2-1 and the second shoji 2-2. It may be configured to change in conjunction with the movement of the first shoji 2-1 and the second shoji 2-2, or to change independently of the movement of the first shoji 2-1 and the second shoji 2-2. For example, a control device provided inside or outside of the composite shoji 100 may control the movement of the first shoji 2-1 and the second shoji 2-2 in conjunction with the movement of at least one of the first shoji 2-1 and the second shoji 2-2. - Change the transparency of at least one of 2. In addition, the control device may operate independently of the movement of the first shoji 2-1 and second shoji 2-2, for example, in conjunction with the external situation of the first shoji 2-1 and second shoji 2-2. Alternatively, the transparency of the first shoji 2-1 and the second shoji 2-2 may be changed according to the user's arbitrary settings.

In addition, when changing the transparency in conjunction with the movement of at least one of the first shoji 2-1 and the second shoji 2-2, in addition to the distance sensor described later, for example, a position sensor, a semi-mechanical switch, a weight sensor, etc. may also be used. The position sensor includes, for example, a resolver that outputs the rotation angle of the wheels that assist the movement of the first shoji 2-1 and the second shoji 2-2 as an AC voltage (analog signal), a rotary encoder, and the first shoji 2-1 and the second shoji 2-2. This includes a linear encoder that detects the straight line position of the second shoji 2-2. Further, the position sensor is not limited to these, and may be any sensor that can detect the moving position of the first shoji 2-1 and second shoji 2-2, and may be a hall sensor, photo interrupter, photoelectric sensor, etc. Good too. The semi-mechanical switch is, for example, a limit switch whose contacts are pushed down and position information is output when the first shoji 2-1 and second shoji 2-2 move. The weight sensor is, for example, a capacitance weight sensor that outputs a signal having a value corresponding to the load from the moving first shoji 2-1 and second shoji 2-2.

In addition, when changing the transparency independently of the movement of the first shoji 2-1 and second shoji 2-2, the transparency is changed according to sunlight, temperature, weather, and time of day (day and night). Alternatively, the transparency may be changed by detecting that a person approaches the first shoji 2-1 and the second shoji 2-2. When using sunlight, for example, the transparency is changed according to the amount of sunlight detected by an irradiation sensor that detects the amount of sunlight irradiated on the first shoji 2-1 and the second shoji 2-2. be able to. When using air temperature, for example, the transparency can be changed depending on the temperature detected by an air temperature sensor that detects the indoor temperature, outside temperature, etc. around the first shoji 2-1 and second shoji 2-2. can. When using the weather, the transparency can be changed depending on weather information distributed over the Internet, for example. When using time periods, for example, by using table information that associates each time period such as early morning, daytime, night, and late night with multiple transparency levels that differ for each time period, you can Transparency can be changed accordingly. When detecting people and changing the transparency, for example, a human sensor that detects people around the first shoji 2-1 and second shoji 2-2 can be used. Examples of the human sensor include an infrared sensor, a temperature sensor, an imaging camera, and a sound sensor. The infrared sensor detects the amount of infrared rays emitted from the surface of the face or body existing around the first shoji 2-1 and the second shoji 2-2, and outputs it as a detection signal. The temperature sensor detects the body temperature of people around the first shoji 2-1 and second shoji 2-2 and outputs it as a detection signal. The imaging camera takes images of people around the first shoji 2-1 and second shoji 2-2 and outputs them as imaged data. The sound sensor collects sounds emitted by people around the first shoji 2-1 and second shoji 2-2, and outputs them as audio data.

Below, a configuration example for changing the transparency of the first shoji 2-1 and the second shoji 2-2 will be described.

The movement of the first shoji 2-1 and the second shoji 2-2 includes, for example, the direction, amount of movement, or position of at least one of the first shoji 2-1 and the second shoji 2-2.

When changing the transparency depending on the direction of movement, the control device changes the transparency of the first shoji 2-1 that moves in the plus X-axis direction (first direction) to the first shoji that moves in the minus X-axis direction (second direction). Control is performed to make the transparency different from 2-1.

Specifically, for example, a distance sensor provided on the pillar portion 12 of the frame 1 measures the distance to the square timber 20b of the first shoji 2-1. The measured distance information is input to the moving direction detection section of the control device.

Based on the input distance information, the moving direction detection unit of the control device determines that the first shoji 2-1 is moving in the plus X-axis direction if the distance becomes longer with the passage of time, A first direction detection signal, which is a signal indicating the direction, is input to the transparency control section.

Furthermore, based on the input distance information, the moving direction detection unit of the control device determines that the first shoji 2-1 is moving in the minus X-axis direction if the distance becomes shorter with the passage of time. Then, a second direction detection signal, which is a signal indicating the direction, is input to the transparency control section.

The transparency control unit controls the first light control unit 3-1 so that when the first direction detection signal is input, the transparency is increased, and when the second direction detection signal is input, the transparency is lowered to approach an opaque state. Control.

Further, the control device may control the transparency of the second light control section 3-2 in the moving direction of the second light control section 3-2, similarly to the first light control section 3-1.

In this way, by changing the transparency depending on the moving direction, for example, when the first shoji 2-1 and the second shoji 2-2 move in a direction closer to each other, by increasing the transparency of each other, a new lattice is created. When the pattern is provided to the user and moves away from each other, the transparency of each other is reduced, thereby providing the user with a grid pattern similar to a conventional shoji screen.

When changing the transparency of the first shoji 2-1 depending on the amount of movement of the first shoji 2-1, for example, a distance sensor provided on the column part 12 of the frame 1 is used to The distance is measured, and the measured distance information is input to the movement amount detection section of the control device.

The movement amount detection unit of the control device compares the distance information input just before the first shoji 2-1 starts moving with the distance information input at the time the first shoji 2-1 completes its movement. For example, if the distance from the pillar part 12 of the frame 1 to the square timber 20b of the first shoji 2-1 changes from 0 mm to 200 mm before and after the movement, the difference will be 200 mm, and this value will be used as the first movement amount information. , input to the transparency control section. In addition, if the distance from the pillar part 12 of the frame 1 to the square timber 20b of the first shoji 2-1 changes from 50 mm to 150 mm before and after the movement, the difference will be 100 mm, and this value will be used as the second movement amount information. , input to the transparency control section.

The transparency control unit refers to table information that associates the amount of movement of the first shoji 2-1 with the transparency of the first shoji 2-1, and adjusts the first dimming so that the transparency corresponds to the amount of movement. Control section 3-1.

Further, the control device may control the transparency of the second light control section 3-2 by the amount of movement of the second light control section 3-2, similarly to the first light control section 3-1.

In this way, by changing the transparency depending on the amount of movement, for example, if the first shoji 2-1 moves slightly, the transparency is controlled to be the same as that of washi paper pasted on a normal shoji, and the first shoji 2-1 moves slightly. If -1 moves significantly, the transparency is controlled to be equivalent to that of transparent glass. As a result, a new lattice pattern is provided to the user in conjunction with the amount of movement of at least one of the first shoji 2-1 and second shoji 2-2 by the user, or a lattice pattern similar to that of the conventional shoji is provided to the user. provided to the user.

When changing the transparency of the first shoji 2-1 depending on the position of the first shoji 2-1, for example, a distance sensor provided on the column part 12 of the frame 1 measures the distance to the square timber 20b of the first shoji 2-1. is measured, and the measured distance information is input to the position detection section of the control device.

The position detection unit detects the position of the square timber 20b of the first shoji 2-1 based on the input distance information. For example, the position of the square timber 20b of the first shoji 2-1 can be detected based on the distance from the particular position, with the position of the pillar 12 as a particular position. The position detection section inputs a position detection signal, which is a signal indicating the detected position, to the transparency control section.

The transparency control unit input to the transparency control unit refers to table information that associates the position of the first shoji 2-1 with the transparency of the first shoji 2-1, and adjusts the transparency so that the transparency corresponds to the position. Controls the first light control section 3-1.

Further, the control device may control the transparency of the second light control section 3-2 at the position of the second light control section 3-2, similarly to the first light control section 3-1.

In this way, by changing the transparency depending on the position, for example, when the first shoji 2-1 is located near the pillar part 12, the transparency is controlled to be equivalent to Japanese paper, and the first shoji 2-1 is controlled to be close to the pillar part 12. 13, the transparency is controlled to be equivalent to that of transparent glass. As a result, a new lattice pattern is provided to the user in conjunction with at least one of the first shoji 2-1 and the second shoji 2-2, or a lattice pattern similar to that of the conventional shoji is provided to the user. .

Further, although the composite shoji 100 of the present embodiment includes two shojis (the first shoji 2-1 and the second shoji 2-2), the composite shoji 100 may include a combination of three or more shojis. . The same applies to the composite shoji 100A, the composite shoji 100B, and the composite shoji 100C.
