1 to 3A are diagrams for explaining an embodiment according to the present invention. Among these, FIG. 1 is a cross-sectional view showing the double window 1. 2 is a longitudinal sectional view of the double window 1 of FIG. 1, that is, a sectional view taken along the line II-II of FIG. FIG. 3A is an enlarged view of the deflection layer 74 in the double window 1 of FIG. 1 to 3A show an example in which a total reflection louver type deflection layer 74 is laminated on the indoor 3 side of the inner window 6.

As shown in FIG. 1 to FIG. 3A, the double window 1 is installed in an opening 4 that opens toward the outdoor 2 and the indoor 3 between the adjacent outdoor 2 and the indoor 3. The outdoor 2 is an example of a first space, and the indoor 3 is an example of a second space. The double window 1 includes an outer window 5 that is an example of a first window and an inner window 6 that is an example of a second window. In the example of FIGS. 1 and 2, two outer windows 5 and two inner windows 6 are arranged.

The inner window 6 is disposed on the indoor 3 side of the outer window 5 and can be moved relative to the outer window 5. Sunlight L is incident on the outer window 5 from the outdoor 2 side, and the incident sunlight L is emitted to the indoor 3 through the inner window 6. In order to reduce the direct light to the indoor 3 and improve the illumination effect of the collected light, the double window 1 is provided with a light control sheet 70. In this embodiment, light incident on the second space (indoor 3 in the figure) from the first space (outdoor 2 in the figure) is treated as sunlight. However, the present invention is not limited to this, and the incident light is derived from artificial light. It may be a thing. The outer window 5 and the inner window 6 are, for example, plate-like members made of glass or resin having visible light permeability. The thicknesses of the outer window 5 and the inner window 6 may be the same or different from each other. For example, the soundproofness can be improved by making the outer window 5 and the inner window 6 different in thickness.

2 and 3A, the light control sheet 70 is disposed on the surface 6a of the inner window 6 on the indoor 3 side, and has a sheet shape as a whole. The inner window 6 shown in FIGS. 1 to 3A is a single glass window. The light control sheet 70 is a sheet that does not have a protruding portion that protrudes greatly toward the indoor 3, thereby effectively avoiding the loss of the aesthetics of the opening 4, and double windows in various openings 4. 1 can be applied.

As shown in FIGS. 1 and 2, the outer window 5 and the inner window 6 are held in the opening 4 by a holder 80. The holder 80 includes an outer window frame 81 that is an example of a first frame, an inner window frame 82 that is an example of a second frame, an outer window holder 83, and an inner window holder 84. The outer window holder 83 and the inner window holder 84 have rails 831 and 841 extending in a direction d2 (hereinafter referred to as a frontage direction) orthogonal to the opening direction d1 of the opening 4. The outer window 5 is held by the outer window holder 83 slidably, for example, slidable along the rail 831 with its outer peripheral edge held by the outer window frame 81. The inner window 6 is held by the inner window holder 84 so as to be movable along the rail 841, for example, slidable and removable, with a part or all of the outer peripheral edge thereof being held by the inner window frame 82. Yes. The inner window 6 may be, for example, rotatable (for example, inwardly opened or rotationally opened) or inclined (for example, inward) with respect to the outer window 5. Moreover, the inner window 6 and the outer window 5 can move non-parallel to the opening direction d1 by being slidable along the rails 831 and 841 extending in the frontage direction d2. The inner window 6 may be fixed to the opening 4, while the outer window 5 may be attached to the opening 4 so as to be able to perform operations such as translation and rotation.

The inner peripheries of the outer window frame 81 and the inner window frame 82 may be the same or different. For example, as shown in FIGS. 1 and 2, the inner window frame 82 may have an inner circumference smaller than the outer window frame 81. As a result, when the outdoor 2 is viewed from the indoor 3 side, the outer window frame 81 is difficult to enter the field of view, so that an aesthetic appearance can be ensured. As shown in FIG. 2, the lower upper end 82 a of the inner window frame 82 is located above (d31 side) the lower upper end 81 a of the outer window frame 81. Thereby, the reflected light L1 can be blocked by the inner window frame 82 so that the reflected light L1 irregularly reflected on the bottom surface of the outer window holder 83 (that is, the rail 831) or the bottom surface of the opening 4 does not travel to the indoor 3 side. As a result of being able to block the reflected light L1 that tends to travel to the indoor 3 side, the antiglare property can be improved. As shown in FIG. 2, the upper lower end 82 b of the inner window frame 82 is positioned below (d32 side) than the upper lower end 81 b of the outer window frame 81. As a result, even if the upper part of the outer window frame 81 functions as an eaves and restricts the amount of light incident on the inner window 6, the upper lower end 82b of the inner window frame 82 is low so that the inner window 6 has an effect of eaves. I hardly receive it. For example, the lower upper end 82a of the inner window frame 82 may be positioned above the lower upper end 81a of the outer window frame 81 in the range of 20 mm to 100 mm. For example, the upper lower end 82b of the inner window frame 82 may be positioned below the upper lower end 81b of the outer window frame 81 in the range of 20 mm to 100 mm.

The thickness of the air layer formed between the outer window 5 and the inner window 6 is not particularly limited, but may be within a range of 50 mm to 150 mm from the viewpoint of soundproofing and heat insulation, for example. Further, if air convection is generated inside the air layer, the heat insulation performance may be lowered. Therefore, in order to suppress the generation of convection, for example, it may be within a range of 50 mm to 80 mm. In addition, the thickness of an air layer refers to the space | interval along the opening direction d1 between the corresponding outer window 5 and the inner window 6. FIG.

The outer window frame 81 and the inner window frame 82 may be formed of a material having lower thermal conductivity than a metal such as aluminum or a metal such as resin or wood. The outer window frame 81 and the inner window frame 82 may be formed by laminating metal, resin, and wood, or mixing wood with resin. As an example, in FIGS. 1 and 2, the outer window frame 81 is formed of metal, and the inner window frame 82 is formed of resin. By using the outer window frame 81 as a metal window frame and the inner window frame 82 as a resin window frame, it is possible to improve heat insulation while suppressing costs. The present invention is not limited to such an embodiment. Both the outer window frame 81 and the inner window frame 82 may be formed of resin. Further, the inner window frame 82 may be made of a material having high thermal conductivity so that latent heat generated in the deflection layer 74 described later can be easily released.

The double window 1 may have a portion having an ultraviolet blocking function that absorbs or reflects ultraviolet rays on the outdoor 2 side of the deflection layer 74. The double window 1 may include a portion having a light diffusion function in the optical path from the outdoor 2 to the indoor 3 for incident light. For example, the outdoor 2 side and / or the indoor 3 side of the deflecting layer 74. Includes a portion having a light diffusion function. For example, as illustrated in FIG. 3A, the light control sheet 70 includes an ultraviolet absorbing adhesive layer 71 that is an example of a portion having an ultraviolet absorbing function, which is laminated on the surface 6 a of the inner window 6 on the indoor 3 side in the following order. The barrier layer 72, the first adhesive layer 73, the deflection layer 74, the second adhesive layer 75, and the light diffusion layer 76 which is an example of a portion having a light diffusion function. As the ultraviolet absorbing function of the portion having the ultraviolet absorbing function, for example, the light transmittance at a predetermined wavelength included in the wavelength range of 380 nm to 200 nm can be set to 5% or less. It is more preferable that the predetermined wavelength is included in a wavelength range of 380 nm to 300 nm because fading due to sunburn of furniture or goods caused by sunlight can be further suppressed.

When at least one of the outer window 5 and the inner window 6 has a light diffusion function, the light diffusion layer 76 can be omitted. In this case, the outer window 5 and / or the inner window 6 can be made of template glass, ground glass, frosted glass, or the like. In this case, the outer window 5 and the inner window 6 are an example of a portion having a light diffusion function provided on the outdoor 2 side of the deflection layer 74.

When at least one of the outer window 5 and the inner window 6 has an ultraviolet blocking function, the ultraviolet absorbing adhesive layer 71 can be omitted. In this case, a film having a function of reflecting or absorbing ultraviolet rays can be bonded to the outer window 5 and / or the inner window 6.

The ultraviolet absorbing adhesive layer 71 is provided on the outdoor 2 side with respect to the deflection layer 74. The light control sheet 70 is fixed to the inner window 6 by the adhesive force of the ultraviolet absorbing adhesive layer 71. The ultraviolet absorbing pressure-sensitive adhesive layer 71 is, for example, an adhesive containing an ultraviolet absorber and having visible light permeability. The ultraviolet absorbing adhesive layer 71 absorbs the ultraviolet light L2 incident from the outdoor 2 side, thereby suppressing the ultraviolet light L2 from entering the deflection layer 74. Thereby, deterioration of the deflection layer 74 due to the ultraviolet ray L2 can be suppressed.

The barrier layer 72 is fixed to the inner window 6 by the adhesive force of the ultraviolet absorbing adhesive layer 71. The barrier layer 72 is a film made of a resin such as PET (polyethylene terephthalate). The barrier layer 72 prevents the ultraviolet absorbent contained in the ultraviolet absorbing adhesive layer 71 from entering the deflection layer 74. Thereby, deterioration of the deflection | deviation layer 74 by an ultraviolet absorber can be suppressed.

The first adhesive layer 73 is, for example, an adhesive that does not contain an ultraviolet absorber and has visible light permeability. The deflection layer 74 is fixed to the barrier layer 72 by the adhesive force of the first adhesive layer 73.

The deflection layer 74 is disposed on the indoor 3 side of the inner window 6. The deflection layer 74 is stacked on the inner window 6 so as to be movable relative to the outer window 5 together with the inner window 6. The deflection layer 74 deflects the visible light L3 incident from the outdoor 2 side and emits it to the indoor 3 side. That is, the deflection layer 74 has a daylighting function of adjusting the optical path of the light in the outdoor 2 and taking the light into the indoor 3. As a specific configuration for the daylighting function, the deflection layer 74 in FIG. 3A includes a deflection layer main body 74a and a base material layer 74b. The base material layer 74b is, for example, a transparent or translucent resin film. The base material layer 74b is provided for manufacturing the deflection layer 74 in accordance with a manufacturing process described later. The base material layer 74b may be omitted.

The deflection layer body 74 a includes a first portion 741, a second portion 742, and a third portion 743. Note that the third portion 743 is integrally formed with the first portion 741 using the same material as the first portion 741. Hereinafter, the first portion 741 and the third portion 743 are collectively referred to as an integral layer 744.

The first portion 741 is bonded to the first adhesive layer 73 on the surface 741a on the outdoor two side. A plurality of substantially wedge-shaped grooves 741b are formed on the surface 741a of the first portion 741 at intervals in the vertical direction d3. Each groove 741b is formed in the first portion 741 over the entire region in the frontage direction d2 (see FIG. 1). The width of each groove 741b in the vertical direction d3 becomes narrower toward the indoor 3 side, that is, the third portion 743 side, and is finally closed in a state where the width is almost zero. The first portion 741 is made of a light transmissive material. This translucent material may be, for example, PET or acrylic resin.

The second portion 742 is provided inside each groove 741b so as to fill each groove 741b.
The second portion 742 has a shape that follows the groove 741b. Specifically, the second portion 742 has a side surface 742a, a steep slope 742b, a gentle slope 742c, and a bottom surface 742d. The side surface 742 a is flush with the surface 741 a of the first portion 741 and is bonded to the first adhesive layer 73. The steep slope 742b extends from the upper end of the side surface 742a toward the indoor 3 side, and is inclined downward d32 toward the indoor 3 side. On the other hand, the gentle slope 742c extends from the end of the steep slope 742b on the indoor 3 side toward the indoor 3 side, and is inclined downward d32 toward the indoor 3 side. The bottom surface 742d connects the lower end of the side surface 742a and the end of the gentle slope 742c on the indoor 3 side, that is, the lower end.

The second portion 742 has a lower refractive index of visible light L3 than the first portion 741. Accordingly, the second portion 742 can totally reflect the visible lights L31 and L32 incident on the inclined surfaces 742b and 742c from the first portion 741 side, that is, the interface with the first portion 741 at an incident angle larger than the critical angle.

The inclination angle θ1 of the steep slope 742b with respect to the opening direction d1 is larger than the inclination angle θ2 of the gentle slope 742c with respect to the opening direction d1. The inclination angle θ2 is 0 ° or more (θ2 ≧ 0). Since the inclination angle θ1 is larger than the inclination angle θ2, the steep slope 742b allows the visible light L31 from a high position on the outdoor 2 to enter at an incident angle larger than the critical angle, and the incident visible light L31 does not rise significantly and does not rise significantly. Total reflection is possible toward the back side of 3. On the other hand, since the inclination angle θ2 is small, the gentle slope 742c allows the visible light L32 from a low position in the outdoor 2 to be incident at an incident angle larger than the critical angle, and the incident visible light L32 does not rise significantly and does not rise significantly. Total reflection is possible toward the back side. By totally reflecting the visible lights L31 and L32 on the back side of the indoor 3, the indoor 3 can be illuminated brightly. That is, the illumination effect of the light taken in can be improved. In FIG. 3A, the visible lights L31 and L32 incident on the steep slope 742b or the gentle slope 742c are shown in a straight line, but in reality, they are refracted, that is, deflected every time they pass through interfaces having different refractive indexes.

The second portion 742 has a main portion 742e that functions as an adhesive, and an optional functional material 742f dispersed in the main portion 742e.

The main portion 742e is formed of a material having a lower refractive index than the first portion 741. The material of the main portion 742e may be a resin material, for example, an ionizing radiation curable resin that is cured by irradiation with ionizing radiation. The ionizing radiation curable resin may be, for example, an ultraviolet curable resin, an electron beam curable resin, a visible light curable resin, or a near infrared curable resin. The linear expansion coefficient of the main portion 742e is desirably the same as or close to the linear expansion coefficient of the first portion 741. By making the linear expansion coefficient of the main portion 742e the same as or close to the linear expansion coefficient of the first portion 741, separation of the second portion 742 from the first portion 741 due to thermal expansion of the main portion 742e can be suppressed.

The functional inclusion 742f is dispersed in the main portion 742e in anticipation of various functions. For example, in order to give the deflection layer 74 a heat shielding function, a heat ray absorbing material may be employed as the functional inclusion 742f. In this case, the heat ray absorbing material may be, for example, transparent inorganic nanoparticles. Inorganic nanoparticles include, for example, antimony tin oxide (ATO), indium tin oxide (ITO), lanthanum hexaboride (LaB6), aluminum doped zinc oxide, indium doped zinc oxide, gallium doped zinc oxide, tungsten oxide, six It may be nanoparticles of cerium boride, anhydrous zinc antimonate and copper sulfide or a mixture thereof. By using the heat-absorbing material, it is possible to suppress an increase in the temperature of the indoor 3 due to the heat rays of the sun, so that the amount of cooling equipment used can be suppressed to save energy and reduce CO ₂ .

Further, in order to impart a light shielding function and designability to the deflection layer 74, a coloring material may be employed as the functional content 742f. In this case, the colorant may be a pigment, and more specifically, a black pigment such as carbon black, graphite, or titanium nitride. By using the black pigment, the deflection layer 74 can exhibit the light blocking function of the visible light L3. Further, bluish particles such as amber, blue, and purple, reddish particles, yellowish particles, and the like may be used as the colorant. The second portion 742 of the deflection layer 74 may be composed of two or more layers having different functions. For example, the layer on the outdoor side of the second portion 742 may have a heat shielding function, and the layer on the indoor side of the second portion 742 may have a design function. By configuring the deflecting layer 74 with two or more layers having different functions, for example, it becomes easy to achieve both a low refractive index and a heat shielding function.

The deflection layer 74 can be manufactured, for example, as follows. First, an integrated layer 744 of the first portion 741 and the third portion 743 is made of a material such as ionizing radiation curable epoxy acrylate. Specifically, a mold roll having a convex portion corresponding to the configuration (that is, arrangement, shape, etc.) of the groove 741b of the first portion 741 is prepared. Next, a sheet of the base material layer 74b is fed between the mold roll and the nip roll, and a curable material is supplied between the mold roll and the base material layer 74b in accordance with the feeding of the sheet. Next, the curable material is pressed with a mold roll and a nip roll so that the liquid curable material supplied onto the base material layer 74b is filled in the concave portion of the mold roll. At this time, the surface 741a and the groove are formed on the curable material while securing the third portion 743 by supplying the curable material onto the base material layer 74b so that the mold roll and the base material layer 74b do not contact each other. The shape of 741b is transferred. Next, the integral layer 744 is obtained by irradiating the curable resin with light to cure (solidify) the curable material. Next, a liquid composition containing a curable material such as urethane acrylate that forms the main portion 742e by curing and a functional content 742f is supplied to the integrated layer 744. Next, the composition is filled into each groove 741b of the first portion 741 using a doctor blade. At this time, the excess composition overflowing out of the groove 741b is scraped off with a doctor blade. Subsequently, the 2nd part 742 is obtained by irradiating ionizing radiation and hardening a composition. In this way, the deflection layer 74 having the base layer 74b and the deflection layer body 74a is manufactured.

FIG. 3B is an enlarged view showing a modification of the deflection layer 74 of FIG. 3A. As shown in FIG. 3B, the deflection layer 74 may be inclined upward d31 as the bottom surface 742d moves toward the indoor 3 side. The deflecting layer 74 may be made of a material having a lower refractive index than the deflecting layer body 74a that does not include the functional inclusion 742f. 3B, the inclination angle θ1 of the steep slope 742b with respect to the opening direction d1 is larger than the inclination angle θ2 of the gentle slope 742c with respect to the opening direction d1. The inclination angle θ2 is 0 ° or more (θ2 ≧ 0). Further, the inclination angle θ3 of the bottom surface 742d with respect to the opening direction d1 is smaller than θ1 (θ1> θ3).

The second adhesive layer 75 is, for example, an adhesive that does not contain an ultraviolet absorber and has visible light permeability. The light diffusion layer 76 is fixed to the deflection layer 74 by the adhesive force of the second adhesive layer 75.

The light diffusion layer 76 is disposed on the indoor 3 side of the deflection layer 74. The light diffusion layer 76 diffuses the visible light L <b> 3 deflected by the deflection layer 74 and emits it to the indoor 3. The light diffusion layer 76 may be, for example, template glass, frosted glass, or frosted glass. According to the light diffusion layer 76, a diffused light distribution obtained by diffusing the visible light L3 deflected by the deflection layer 74 can be obtained, so that the indoor 3 can be illuminated uniformly and brightly. In addition, by providing the light diffusion layer 76, it is possible to reduce the glare that can be seen from the indoor side according to the repeated arrangement of the first portion 741 and the second portion 742 having different refractive indexes. .

The double window 1 configured as described above can be assembled using, for example, a double window kit including the inner window 6, the light control sheet 70, the inner window frame 82, and the inner window holder 84 as follows. it can. In the following example, it is assumed that the outer window 5, the outer window frame 81, and the outer window holder 83 are already provided in the opening 4. First, the light control sheet 70 is affixed to the inner window 6 via the ultraviolet absorbing adhesive layer 71. The light control sheet 70 may be attached at any of the manufacturing stage of the inner window 6 and the assembly stage (that is, the construction stage) of the double window 1. The light control sheet 70 before being attached to the inner window 6 may have a release sheet attached to the ultraviolet absorbing adhesive layer 71. When affixing the adhesive layer of the light control sheet 70 to the inner window 6 through water, when the water control is performed so that the end of the light control sheet 70 is positioned about several mm inside the end of the inner window 6, It is easy to drain water between the window 6 and the light control sheet 70. Next, the inner window frame 82 is attached to the outer periphery of the inner window 6 and the light control sheet 70. The inner window frame 82 may be attached either before the assembly step to the opening of the double window 1 or during the assembly step to the opening of the double window 1. Next, the inner window holder 84 is installed in the opening 4 so as to be adjacent to the outer window holder 83 on the indoor 3 side. The inner window holder 84 may be installed by fixing the inner window holder 84 to the opening 4 by screwing or the like. Next, the inner window 6 is fitted into the inner window holder 84 and attached. Thus, the double window 1 can be easily assembled by combining the existing outer window 5 and the double window kit. In addition, when there is not enough space for installing the inner window holder 84 in the opening 4 or there is a step in the opening 4, an auxiliary material called a fusible frame at the lower end on the indoor 3 side of the opening 4 May be installed.

In FIG. 2, the inner window holder 84 is mounted substantially horizontally. For example, it is assumed that the inner window 6 is attached to be within 3 ° from the horizontal. However, when the inner window holder 84 is greatly inclined from the horizontal, the reflection surface of the deflection layer 74 laminated on the inner window 6 may take an angle that is not intended in design. In such a case, the angle of the inner window 6 may be adjusted by disposing an angle adjusting attachment (not shown) below the inner window holder 84.

In FIG. 3A, the second portion 742 of the deflection layer 74 has a reflective surface that is asymmetric in a longitudinal sectional view. When the inner window 6 is configured to be detachable from the inner window holder 84, it is asymmetrical by attaching the inner window 6 to the inner window holder 84 by turning it upside down in consideration of the incident angle of light and the necessity of daylighting. You may use a reflective surface properly.

First, sunlight L from the outdoors 2 enters the outer window 5 in the double window 1 assembled as described above. The sunlight L that has entered the outer window 5 passes through the outer window 5 and then enters the inner window 6. At this time, part of the sunlight L that has passed through the outer window 5 can enter the outer window holder 83 or the bottom surface of the opening 4 and be irregularly reflected. The irregularly reflected irregularly reflected light L1 is not properly incident on the inclined surfaces 742b and 742c of the deflecting layer 74 and cannot be deflected in the intended direction. On the other hand, in this embodiment, since the lower upper end 82a of the inner window frame 82 is at a high position, the irregularly reflected light L1 can be blocked. Thereby, the glare resulting from the irregularly reflected light L1 can be suppressed, and the antiglare property can be improved.

Next, the sunlight L incident on the inner window 6 is incident on the ultraviolet absorbing adhesive layer 71 immediately after passing through the inner window 6. Of the sunlight L incident on the ultraviolet absorbing adhesive layer 71, the ultraviolet L2 is absorbed by the ultraviolet absorbing adhesive layer 71 and hardly transmits. Since the ultraviolet ray L2 hardly passes through the ultraviolet absorbing adhesive layer 71, the incidence of the ultraviolet ray L2 on the deflection layer 74 located on the emission side of the ultraviolet absorbing adhesive layer 71 is suppressed. Thereby, deterioration of the deflection layer 74 due to the ultraviolet ray L2 can be suppressed. On the other hand, of the sunlight L incident on the ultraviolet absorbing adhesive layer 71, the visible light L3 passes through the ultraviolet absorbing adhesive layer 71 with almost no absorption.

The visible light L3 that has passed through the ultraviolet absorbing adhesive layer 71 passes through the barrier layer 72 and the first adhesive layer 73 in order and then enters the deflection layer 74.

Of the deflection layer 74, the visible light L3 incident on the surface 741a of the first portion 741 travels inside the first portion 741, and has an interface 742b with the second portion 742 having a lower refractive index than the first portion 741. Incident to 742c. At this time, since the steep slope 742b has a posture (θ1> θ2) nearly parallel to the visible light L31 from a high position, the visible light L31 from a high position is larger than the critical angle on the steep slope 742b. Easy to enter at an incident angle. Thereby, the visible light L31 from a high position can be reliably totally reflected by the steep slope 742b. Further, since the steep slope 742b is inclined downward d32, the total reflection direction by the steep slope 742b is close to the horizontal direction, that is, the opening direction d1. Thereby, the rising of visible light L31 from a high position can be suppressed, and visible light L31 can be totally reflected toward the back side of indoor 3. On the other hand, since the gentle slope 742c has a posture (θ2 ≧ 0) that is nearly parallel to the visible light L32 from a low position, the visible light L32 from the low position is more than the critical angle on the gentle slope 742c. Easy to enter at a large incident angle. Thereby, the visible light L32 from a low position can be reliably totally reflected by the gentle slope 742c. Further, since the gentle slope 742c is inclined downward d32, the total reflection direction by the gentle slope 742c is close to the horizontal direction. Thereby, the rising of the visible light L32 from a low position is suppressed, and the visible light L32 can be totally reflected toward the back side of the indoor 3.

On the other hand, in the deflection layer 74, the visible light L3 incident on the side surface 742a of the second portion 742 is incident on the functional content 742f and is affected by the functional content 742f. For example, when the functional inclusion 742f is a heat-absorbing material, the heat of visible light L3 can be absorbed and the transfer of heat to the indoor 3 side can be suppressed.

Next, the visible light L 3 emitted from the deflection layer 74 passes through the second adhesive layer 75 and enters the light diffusion layer 76. The visible light L3 incident on the light diffusion layer 76 is diffused and emitted to the indoor 3.

According to this embodiment, the light from the outdoor 2 is deflected by the deflecting layer 74 and taken into the indoor 3, so that the illumination effect of the taken light can be improved while avoiding direct light.

It is also possible to obtain a clear view in a timely manner by moving the inner window 6 which is a sliding window in the frontage direction d2 to an open state and opening one side.

When at least one of the outer window 5 and the inner window 6 has a light diffusion function, the light diffusion layer 76 can be omitted. In this case, the outer window 5 and / or the inner window 6 can be made of template glass, ground glass, frosted glass, or the like.

When at least one of the outer window 5 and the inner window 6 has an ultraviolet blocking function, the ultraviolet absorbing adhesive layer 71 can be omitted. In this case, a film having a function of reflecting or absorbing ultraviolet rays can be bonded to the outer window 5 and / or the inner window 6.

The double window 1 of the present embodiment is not limited to the configuration shown in FIGS. 1 to 3A, and can be variously changed as shown in the following modifications. In the following description and the drawings used in the following description, the same reference numerals as those used for the corresponding parts in the above embodiment are used for the parts that can be configured in the same manner as in the above embodiment. The duplicated explanation is omitted.

(First modification)
In the embodiment described with reference to FIGS. 1 to 3, the example in which the deflection layer 74 is laminated on the indoor side of the inner window 6 is shown. However, as shown in FIG. 4 as a first modification, the deflection layer 74 may be laminated on the outdoor side of the second window.

FIG. 4 is a longitudinal sectional view showing an example in which a deflection layer 74 is laminated on the outdoor 2 side of the inner window 6 as the double window 1 according to the first modification. In the double window 1 of the second modification, the light control sheet 70 is laminated in the following order on the surface 6b on the outdoor 2 side of the inner window 6, in the following order: an adhesive layer 202, a light diffusion layer 76, an adhesive layer 75, It has the hard coat layer 201 which is an example of the part which has the deflection | deviation layer 74 and an ultraviolet-ray absorption function.

The hard coat layer 201 has weather resistance, light transmissivity, and scratch resistance that hardly causes deterioration due to ultraviolet rays, heat, water, chemicals, temperature changes, and the like. The hard coat layer 201 may be formed, for example, by applying an electron beam curable transparent resin to which an ultraviolet absorber is added on the deflecting layer 74 and curing the applied transparent resin by electron beam irradiation.

Note that an ultraviolet adhesive layer 71 similar to that shown in FIG. 3A may be disposed between the hard coat layer 201 and the deflection layer 74. When the outer window 5 has an ultraviolet blocking function, the ultraviolet absorbing adhesive layer 71 can be omitted, or the ultraviolet adhesive layer 71 and the outer window 5 having an ultraviolet blocking function can be used in combination. Further, instead of providing the light diffusion layer 76, the inner window 6 itself may have a light diffusion function. When the inner window 6 itself has a light diffusing function, the inner window 6 may be a template glass, frosted glass, or frosted glass, or a light diffusing agent is dispersed in the inner window 6 or a layer having a light diffusing function is provided. Or you may.

Also in the first modified example, the visible light L3 can be deflected by the deflecting layer 74 and taken into the indoor 3 in the same way as the double window 1 of the above-described embodiment and modified example, so that direct light is reduced. However, the illumination effect of the light taken in can be improved. Moreover, the visible light L3 deflected by the deflection layer 74 is diffused by the light diffusion layer 76, so that the indoor 3 can be illuminated brightly. Further, by absorbing the ultraviolet ray L2 by the hard coat layer 201, the deterioration of the deflection layer 74 due to the ultraviolet ray L2 can be suppressed. Further, since the deflection layer 74 can be protected by the hard coat layer 201, the weather resistance of the deflection layer 74 can be improved. Further, in the first modified example, since the deflection layer 74 is disposed so as to avoid the indoor side, the chance of dirt adhering to the surface of the deflection layer 74 is reduced.

(Second modification)
In the embodiment described with reference to FIGS. 1 to 3, an example in which the deflection layer 74 is laminated on the inner window 6 has been shown. However, as shown in FIG. 5 as a second modification, the deflection layer 74 may be laminated on the outer window 5.

FIG. 5 is a longitudinal sectional view showing an example in which a deflection layer 74 is laminated on the indoor 3 side of the outer window 5 as the double window 1 according to the second modification. FIG. 5 corresponds to a case in which the inner window 6 in FIG. That is, instead of laminating the light control sheet 70 shown in FIG. 3A on the surface of the inner window 6 on the indoor 3 side, the light control sheet 70 may be laminated on the surface of the outer window 5 on the indoor 3 side. When the outer window 5 has an ultraviolet blocking function, the ultraviolet absorbing adhesive layer 71 can be omitted. According to the second modification, the deflecting layer 74 is disposed on the outer window 5 side, not on the inner window 6 that is in contact with the indoor 3 and is likely to cause condensation. Therefore, it is possible to suppress the occurrence of mold on the deflection layer 74 or the occurrence of peeling due to condensation.

Also in the second modified example, similarly to the double window 1 of the above-described embodiment and modified example, it is possible to improve the illumination effect of the light taken in while reducing the direct light by the deflection layer 74. In the second modified example, since the deflection layer 74 is arranged so as to avoid the indoor side, the chance that dirt adheres to the surface of the deflection layer 74 is reduced.

(Third Modification)
In the second modification described with reference to FIG. 5, the example in which the deflection layer 74 is laminated on the indoor side of the inner window 6 is shown. However, as shown in FIG. 6 as a third modification, the deflection layer 74 may be laminated on the outdoor side of the outer window 5.

FIG. 6 is a longitudinal sectional view showing an example in which a deflection layer 74 is laminated on the outdoor 2 side of the outer window 5 as the double window 1 according to the third modification. FIG. 6 corresponds to the first modified example (FIG. 4) in which the inner window 6 is replaced with the outer window 5. That is, instead of laminating the light control sheet 70 shown in FIG. 4 on the surface of the inner window 6 on the outdoor 2 side via the adhesive layer 202, the adhesive layer 202 is formed on the surface of the outer window 5 on the outdoor 2 side. You may laminate through. Further, in the example shown in FIG. 6, the deflection layer 74 is disposed on the outdoor 2 side from the outer window 5, and thus is more easily deteriorated due to scratches and wind and rain than when disposed on the indoor 3 side. For this reason, on the outdoor 2 side of the deflection layer 74, a hard coat layer 201 having not only an ultraviolet absorbing function but also excellent scratch resistance and water resistance is disposed. By disposing the hard coat layer 201, deterioration of the deflection layer 74 due to scratches or wind and rain can be suppressed. Further, on the indoor 3 side of the deflection layer 74, a light diffusion layer 76 is arranged in the same manner as in the embodiment and the modification described above. The light diffusion layer 76 may be fixed to the deflection layer 74 via an adhesive layer, or may be coated on the deflection layer 74. According to the third modified example, the deflecting layer 74 is disposed on the outer window 5 side, not on the inner window 6 where the dew layer 74 is in contact with the indoor 3 and condensation is likely to occur. Therefore, it is possible to suppress the occurrence of mold on the deflection layer 74 or the occurrence of peeling due to condensation.

Also in the third modified example, similarly to the double window 1 of the above-described embodiment and modified example, it is possible to improve the illumination effect of the light taken in while avoiding direct light by the deflection layer 74.

(Fourth modification)
In the embodiment described with reference to FIGS. 1 to 3, an example in which the deflection layer 74 is laminated on the inner window 6 has been shown. However, as shown in FIG. 7 as a fourth modification, the deflection layer 74 may be included in the inner window 6 as a part of the inner window 6.

FIG. 7 is a longitudinal sectional view showing an example in which a deflection layer 74 is arranged inside the inner window 6 as the double window 1 according to the fourth modification. The inner window 6 of the fourth modification is an embodiment of double-glazed glass, and the deflection layer 74 is combined with double-glazed glass. Specifically, the inner window 6 of the fourth modified example includes, in order from the outdoor 2 side, a first inner window substrate 61, a light control sheet 70 having the configuration shown in FIG. 3A, an intermediate layer 63, and a second inner window. And a window substrate 62. Although not shown, at least one of the first inner window substrate 61 and the second inner window substrate 62 may be provided with a thermal barrier coating called a Low-E metal film. The first inner window substrate 61 and the second inner window substrate 62 are connected by a frame-shaped spacer 301 disposed between the peripheral portions of the inner window substrates 61 and 62. A sealant 302 is provided on the outer peripheral surface of the spacer 301. The intermediate layer 63 may be filled with an inert gas such as air or argon, or the intermediate layer 63 may be in a vacuum state.

In the example shown in FIG. 7, the deflection layer 74 is laminated on the first inner window substrate 61, but the deflection layer 74 in the second modification (see FIG. 4) is formed on the second inner window substrate 62. It may be laminated on top. The second window 6 including the deflection layer 74 has a configuration called a so-called pair glass as a whole, a pair of inner window substrates 61 and 62 whose relative positions are positioned and a gap is formed between them. have. However, the present invention is not limited to the illustrated example, and the inner window 6 may have a configuration called so-called laminated glass, and the intermediate layer 63 may be deleted. Further, the number of substrates constituting the inner window 6 may be three or more. The distance between the first inner window substrate 6 and the second inner window substrate 62 may be, for example, within 20 mm in consideration of heat insulation.

Also in the fourth modified example, similarly to the double window 1 of the above-described embodiment and modified example, it is possible to improve the illumination effect of the light taken in while reducing the direct light by the deflection layer 74. Moreover, since the heat insulation effect can be enhanced by using the double-glazed glass, the energy consumption for operating the air conditioner can be suppressed.

In another embodiment in which the deflection layer 74 or the light control sheet 70 is disclosed as a component different from the inner window 6 or the outer window 5, at least one of the inner window 6 and the outer window 5 has two or more transparent plates. You may employ | adopt the structure called a pair glass and a laminated glass, and a structure which has an optical substrate.

(Fifth modification)
In the fourth modified example described with reference to FIG. 7, the example in which the deflection layer 74 is included in the inner window 6 as a part of the inner window 6 is shown. However, as shown in FIG. 8 as a fifth modification, the deflection layer 74 may be included in the outer window 5 as a part of the outer window 5.

FIG. 8 is a longitudinal sectional view showing an example in which a deflection layer 74 is arranged inside the outer window 5 as the double window 1 according to the fifth modification. In the 4th modification, although the inner window 6 was the aspect of multilayer glass, in the 6th modification, the outer window 5 is the aspect of multilayer glass. FIG. 8 corresponds to a structure in which the first inner window substrate 61 in FIG. 7 is replaced with the first outer window substrate 51 and the second inner window substrate 62 in FIG. 7 is replaced with the second outer window substrate 52. Similarly to the fourth modification, the intermediate layer 63 may be deleted.

Also in the fifth modified example, similarly to the double window 1 of the above-described embodiment and modified example, it is possible to improve the illumination effect of the light taken in while avoiding direct light by the deflection layer 74. Moreover, the energy consumption of an air conditioner can be reduced by improving the heat insulation effect of the double window 1.

(Sixth Modification)
In the above-described embodiment and modification, an example in which the deflection layer 74 is laminated on the inner window 6 or the outer window 5 or forms a part of the inner window 6 or the outer window 5 has been described. However, as shown in FIG. 10 as a sixth modified example, the deflection layer 74 may be disposed apart from the inner window 6 and the outer window 5. For example, the deflection layer 74 may be provided with a gap with respect to the inner window 6 and the outer window 5, and may be movable relative to the inner window 6 and the outer window 5. Further, the deflecting layer 74 may be configured to always face the outer window 5, or drawn out from a storage space (not shown) at the upper end or the lower end inside the opening 4 to be in time with the outer window 5. You may be comprised so that it may oppose. Thereby, the user can freely select the field of view.

FIG. 9 is a longitudinal sectional view showing an example in which a deflection layer 74 is arranged on the outdoor 2 side of the outer window 5 through a gap as the double window 1 according to the sixth modification. The deflection layer 74 of the sixth modification is held by the holder 401 at the end of the opening 4 on the outdoor 2 side. More specifically, the deflection layer 74 is movable, for example, slidable along the rail 402 of the holder 401 extending in the frontage direction d2 in the frontage direction d2. The movement of the deflection layer 74 can be performed independently of the movement of the outer window 5 and the movement of the inner window 6. Note that the holder 401 may be integrated with the outer window holder 83, and the deflection layer 74 may not be able to move relative to the outer window holder 83. The deflection layer 74 may be parallel to the outer window 5 and the inner window 6 or may be non-parallel. If standing, the position of the holder 401 may be adjusted, and the deflection layer 74 may be inclined with respect to the outer window 5 to be configured like a shade.

Since the deflection layer 74 of the sixth modified example is disposed on the outdoor 2 side from the outer window 5, it is more likely to be deteriorated due to scratches or wind and rain than when disposed on the indoor 3 side. For this reason, on the outdoor 2 side of the deflection layer 74, a hard coat layer 201 having not only an ultraviolet absorbing function but also excellent scratch resistance and water resistance is disposed. By disposing the hard coat layer 201, deterioration of the deflection layer 74 due to scratches or wind and rain can be suppressed. Further, on the indoor 3 side of the deflection layer 74, a light diffusion layer 76 is arranged in the same manner as in the embodiment and the modification described above. The light diffusion layer 76 may be fixed to the deflection layer 74 via an adhesive layer, or may be coated on the deflection layer 74.

Also in the sixth modified example, similarly to the double window 1 of the above-described embodiment and modified example, it is possible to improve the illumination effect of the light taken in while avoiding direct light by the deflection layer 74. In addition, by arranging the deflection layer 74 on the outdoor 2 side of the outer window 5, light with a high incident angle can be deflected in the direction of a low incident angle, and reflection loss at the window surface can be minimized. More light amount of sunlight L can be taken in by the deflection layer 74.

(Seventh Modification)
In the sixth modified example described with reference to FIG. 9, the deflection layer 74 is provided at a position on the outdoor side with respect to the outer window 5 with a gap from the inner window 6 and the outer window 5. An example is shown. However, as shown in FIG. 10 as a seventh modified example, the deflection layer 74 is provided at a position between the outer window 5 and the inner window 6 via a gap with respect to the inner window 6 and the outer window 5. It may be done. Further, the deflecting layer 74 may be configured to always face the outer window 5 and the inner window 6, or may be drawn out from the storage space (not shown) at the upper or lower end inside the opening 4. You may be comprised so that it may oppose the window 5 and the inner window 6 timely. Thereby, the user can freely select the field of view.

FIG. 10 is a longitudinal sectional view showing an example in which a deflection layer 74 is arranged on the indoor 3 side of the outer window 5 through a gap as the double window 1 according to the seventh modification. Further, in the double window 1 according to the seventh modified example, the deflection layer 74 is disposed on the outdoor 2 side of the inner window 6 from the inner window 6 via a gap. The deflection layer 74 of the seventh modified example is held by the holder 801 between the outer window 5 and the inner window 6 in the opening 4. More specifically, the deflection layer 74 is movable in the frontage direction d2 along the rail 802 of the holder 801 extending in the frontage direction d2, and is slidable. In addition, although the deflection | deviation layer 74 of FIG. 10 is 1 sheet sash, you may make it 2 sheets. In the double window 1 of the seventh modified example, a hard coat layer 201 containing an ultraviolet absorber is disposed on the outdoor 2 side of the deflecting layer 74 as in the sixth modified example (FIG. 9). A light diffusion layer 76 is disposed on the indoor 3 side of the deflection layer 74. The movement of the deflection layer 74 can be performed independently of the movement of the outer window 5 and the movement of the inner window 6. Note that the holder 801 may be integrated with the inner window holder 84, and the deflection layer 74 may not be able to move relative to the outer window holder 83.

Also in the seventh modified example, similarly to the double window 1 of the above-described embodiment and modified example, it is possible to improve the illumination effect of the light taken in while avoiding direct light by the deflection layer 74.

(Eighth modification)
In the sixth and seventh modified examples described with reference to FIGS. 9 and 10, the deflection layer 74 is located on the outdoor side of the outer window 5 or at a position between the outer window 5 and the inner window 6. An example is shown in which the inner window 6 and the outer window 5 are provided via gaps. However, as shown in FIG. 11 as an eighth modification, the deflection layer 74 is provided at a position closer to the indoor side than the inner window 6 with respect to the inner window 6 and the outer window 5 via a gap. Also good. Further, the deflecting layer 74 may be configured to always face the inner window 6, or may be drawn out from a storage space (not shown) at the upper or lower end inside the opening 4 to be in time with the inner window 6. You may be comprised so that it may oppose. Thereby, the user can freely select the field of view.

FIG. 11 is a longitudinal sectional view showing an example in which a deflection layer 74 is disposed on the indoor 3 side of the inner window 6 through a gap as the double window 1 according to the eighth modification. The deflection layer 74 of the eighth modification is held by the holder 801 on the indoor side of the inner window 6 in the opening 4. More specifically, the deflection layer 74 is movable in the frontage direction d2 along the rail 802 of the holder 801 extending in the frontage direction d2, and is slidable. In addition, although the deflection | deviation layer 74 of FIG. 11 is 1 sheet sash, you may make it 2 sheets. In the double window 1 of the eighth modified example, a hard disk containing an ultraviolet absorber on the outdoor 2 side of the deflecting layer 74 as in the sixth modified example (FIG. 9) and the seventh modified example (FIG. 10). A coat layer 201 is disposed. A light diffusion layer 76 is disposed on the indoor 3 side of the deflection layer 74. The movement of the deflection layer 74 can be performed independently of the movement of the outer window 5 and the movement of the inner window 6. Note that the holder 801 may be integrated with the inner window holder 84, and the deflection layer 74 may not be able to move relative to the outer window holder 83.

Also in the eighth modified example, similarly to the double window 1 of the above-described embodiment and modified example, it is possible to improve the illumination effect of the light taken in while avoiding direct light by the deflection layer 74.

(Ninth Modification)
In the embodiment and the modification described above, the example in which the normal line direction to the sheet surface of the deflection layer 74 is directed in a certain direction has been described. However, the present invention is not limited to this example, and the deflection layer 74 may be supported so that the normal direction to the sheet surface of the deflection layer 74 can be changed.

FIG. 12 is a perspective view showing a deflection layer 74 supported as a double window 1 according to a ninth modification so as to be rotatable about a predetermined axis. The deflection layer 74 of the ninth modification includes a louver type deflection layer (see FIG. 3A and the like) that deflects light by total reflection, a louver type deflection layer (see FIG. 20) that deflects light by specular reflection, and a prism type. The deflection layer (see FIG. 18) and the craze type deflection layer (see FIG. 19) may be used.

As shown in FIG. 12, the deflection layer 74 of the ninth modification is supported rotatably about an axis extending in the frontage direction d2. Specifically, the double window 1 according to the fourteenth modification includes a support shaft member 142 connected to the deflection layer 74 and a drive device 143 capable of driving the support shaft member 142. The support shaft member 142 extends in the frontage direction d2.

In addition, as shown in FIG. 12, you may support the deflection | deviation layer 74 rotatably centering on the axis line 144 extended in the perpendicular direction d3.

According to the ninth modification, by rotating the deflection layer 74, the orientation of the deflection layer 74 can be adjusted according to the installation position, time, time, and the like. Thereby, like the 1st modification, the deflection | deviation layer 74 can exhibit scheduled functions, such as a daylighting function, a light shielding function, a heat shielding function, with respect to sunlight irrespective of time and time. For example, when the orientation of the deflection layer 74 is adjusted so that the bottom surface 742d of the deflection layer 74 in FIG. 3A is at the top, the light that has been totally reflected when the steep slope 742b and the gentle slope 742c are at the top, Therefore, it is not totally reflected and is absorbed by the main portion 742e and the functional inclusion 742f, whereby a high heat shielding function is obtained.

(10th modification)
In the ninth modification described with reference to FIG. 12, the example in which the deflection layer 74 is supported so that the orientation of the deflection layer 74 can be changed has been described. However, the specific configuration shown in FIG. 12 is merely an example of a support method that allows the orientation of the deflection layer 74 to be varied. FIGS. 13 to 16 show another example of a configuration for supporting the deflection layer 74 so that the orientation of the deflection layer 74 can be changed as a tenth modification.

FIG. 13 is a longitudinal sectional view showing an example in which a deflection layer 74 is arranged on the indoor 3 side of the inner window 6 through a gap as the double window 1 according to the tenth modification. FIG. 14 is a perspective view showing a double window 1 according to a tenth modification. FIG. 15 is an enlarged perspective view of the deflection layer 74 in the double window 1 of the tenth modification. In FIG. 15, the main portion 742e and the functional inclusion 742f (see FIG. 3A) constituting the second portion 742 are not shown.

As shown in FIG. 14, the double window 1 of the tenth modification includes a plurality of strip-shaped deflection layers 74 arranged in the vertical direction d <b> 3 and each deflection layer 74 so that the orientation of each deflection layer 74 can be changed. And a support member 101 that supports In the tenth modification, the deflection layer 74 has a so-called blind mode. As shown in FIG. 13, the deflection layer 74 is arranged at a position facing the inner window 6 on the indoor 3 side. The deflection layer 74 of the tenth modified example is also called a slat or a blade plate, and is formed as a thin plate-like member that is elongated in the frontage direction d2. As shown in FIG. 15, the deflection layer 74 of the tenth modification is formed in a slightly curved thin plate shape.

Further, as shown in FIG. 14, the double window 1 of the tenth modified example has a mounting box 102, a ladder cord 103, a lifting / lowering cord 104, and an operation grip 105. The attachment box 102 is a fixture for attaching the deflection layer 74 to the wall. The ladder cord 103 hangs down from the mounting box 102 and supports each deflecting layer 74 in a state of being spaced apart in the vertical direction d3. The lifting / lowering cord 104 can pull up the deflection layer 74. The operation grip 105 is connected to the lifting / lowering cord 104, the ladder cord 103 and the lifting / lowering cord 104.

The ladder code 103 controls the direction of each deflection layer 74, that is, the normal direction of the sheet surface of each deflection layer 74, so that each deflection layer 74 is substantially parallel. By operating the ladder code 103 via the operation grip 105, the direction of the deflection layer 74 can be adjusted. At this time, the direction of each deflection layer 74 is changed so as to rotate about an axis parallel to the longitudinal direction d2.

Further, by operating the lifting / lowering cord 104 via the operation grip 105, each deflection layer 74 can be pulled up so as to narrow the interval in the vertical direction d3 sequentially from the deflection layer 74 on the lower d32 side. At this time, at least a part of each deflection layer 74 is accommodated in the mounting box 102, and the inner window 6 is exposed to the indoor 3. Similarly, by operating the lifting / lowering cord 104 via the operation grip 105, the deflection layer 74 gathered upward can be lowered to a position facing the inner window 6.

For example, as shown in FIG. 13, when the sheet surface of the deflection layer 74 extends substantially in the vertical direction d3, various functions expected for the deflection layer 74 with respect to sunlight L from the outdoors 2, for example, A lighting function, a light shielding function, a heat shielding function, etc. can be exhibited. In addition, when the altitude of the sun changes, the deflection layer 74 is changed with respect to the sunlight L from the sun whose altitude is changed by changing the direction of all the deflection layers 74 using the ladder code 103. Effectively perform planned functions.

FIG. 16 is a longitudinal sectional view showing a deflecting layer 74 in a different direction from FIG. 13 in the tenth modification. When the sunlight L is to be taken into the indoor 3 as it is, the direction of the deflection layer 74 may be adjusted as shown in FIG. 16 so that the sunlight L passes between the neighboring deflection layers 74. . According to this method, compared with the case where sunlight L permeate | transmits the 1st part 741 of the light control sheet 70, it becomes possible to take in sunlight L in the indoor 3 with a higher transmittance | permeability. Moreover, when the 2nd part 742 contains the functional substance 742f (refer FIG. 3A) which has visible-light-shielding property, in the state shown by FIG. It is also possible to prevent peeping from the opening direction d1.

As described above, according to the tenth modification example, as in the configuration of FIGS. 1 to 3A, the light from the outdoor 2 is deflected by the deflecting layer 74 and taken into the indoor 3 so that the direct light can be obtained. While avoiding, the illumination effect of the light taken in can be improved. In addition, by adjusting the orientation of the deflection layer 74 according to the installation position, time, time, etc., the deflection layer 74 has a daylighting function, a light shielding function, a heat shielding function, etc. The planned function can be demonstrated.

(Eleventh modification)
The deflection layer 74 illustrated in the embodiment and the modification described above has a size facing the entire area of the outer window 5 and the inner window 6. However, the present invention is not limited to this example, and the deflection layer 74 may be disposed only in a part of the region facing the outer window 5 or may be disposed only in a part of the region facing the inner window 6. Good.

FIG. 17 is a longitudinal sectional view showing an example in which the deflection layer 74 is partially arranged on the inner window 6 and the outer window 5 as the double window 1 according to the eleventh modification. In the example shown in FIG. 17, the deflection layer 74 is disposed in a region facing the upper half of the outer window 5 and a region facing the lower half of the inner window 6. More specifically, the deflection layer 74 shown in FIG. 17 is partially laminated on the surface 5 a on the indoor 3 side of the outer window 5 and the surface 6 a on the indoor 3 side of the inner window 6. Although the deflection layer 74 of FIG. 17 is laminated on the upper half of the surface 5a of the outer window 5 and the lower half of the surface 6a of the inner window 6, it is not limited to such a configuration.

For example, the deflection layer 74 may be laminated on the lower half of the surface 5 a of the outer window 5 and the upper half of the surface 6 a of the inner window 6. Further, the deflection layer 74 may be laminated at the central portion in the vertical direction d3 of the surface 5a of the outer window 5 or the surface 6a of the inner window 6. By arranging the deflection layer 74 at the center of the outer window 5 or the inner window 6 in the vertical direction d3, it is deflected from below the height of the human line of sight, depending on the height of the opening 4 and the depth in the frontage direction. It is possible to suppress the light from reaching the human eye directly, or it is possible to omit the arrangement of the deflecting layer 74 in a region that becomes trapped by the opening 4 and is difficult to be effectively used. Further, the deflection layer 74 may be partially laminated on the surface 5 b on the outdoor 2 side of the outer window 5 and the surface 6 b on the outdoor 2 of the inner window 6. Further, the deflection layer 74 may be partial to the surfaces 5a and 5b of the outer window 5 and the surfaces 6a and 6b of the inner window 6 not only in the vertical direction d3 but also in the frontage direction d2. Good. Alternatively, the deflection layer 74 having a size that is partially projected on the inner window 6 and the outer window 5 in the opening direction d1 is provided on the outdoor 2 side of the outer window 5, between the outer window 5 and the inner window 6, or on the inner side. You may arrange | position to the indoor 3 side of the window 6 through a space | gap. Moreover, even if the deflection layer 74 is partially laminated on the inner window substrates 61 and 62 or the outer window substrates 51 and 52 in the multi-layer glass mode shown in the fourth and fifth modifications. Good.

Also in the eleventh modification, similarly to the double window 1 of the embodiment and the modification described above, the illumination effect of the light taken in while avoiding direct light by the deflection layer 74 can be improved. Moreover, it is also possible to secure a view of the outdoor 2 from the indoor 3 by securing a transparent region where the deflection layer 74 is not disposed in a part of the outer window 5 and the inner window 6.

(Twelfth modification)
In the embodiment and the modification described above, the specific configuration of the deflection layer 74 that deflects the traveling direction of light incident from the first space and guides it to the second space has been described. However, the configuration of the deflection layer 74 described above is only an example, and various configurations can be employed.

FIG. 18 is a longitudinal sectional view showing a prism type deflection layer 74 as the double window 1 according to the twelfth modification. As shown in FIG. 18, the deflection layer 74 of the twelfth modification is a prism form. Specifically, as shown in FIG. 18, the deflection layer 74 has a prism surface 7400, and deflects the visible light L <b> 3 by reflection or refraction at the prism surface 7400 to be taken into the indoor 3.

More specifically, the deflection layer 74 of the twelfth modification has a sheet-like main body portion 7401 and a plurality of unit prisms 7402 arranged on the main body portion 7401. The main body portion 7401 and the unit prism 7402 are made of a translucent material. In the example of FIG. 18, the unit prisms 7402 are arranged in the vertical direction d3 and extend in the frontage direction d2. Each unit prism 7402 is arranged on one surface of the main body portion 7401 without any gap.

The unit prism 7402 has a first surface 7402a and a second surface 7402b arranged to face each other in the vertical direction d3. The deflection layer 74 reflects, in particular, totally reflects the visible light L3 incident on the unit prism 7402 from one of the first surface 7402a and the second surface 7402b on the other of the first surface 7402a and the second surface 7402b. Accordingly, the deflection layer 74 can deflect the visible light L3 and emit it to the indoor 3 side.

Also in the twelfth modification, the illumination effect of the light taken in while avoiding the direct light can be improved by the deflection layer 74 as in the double window 1 of the embodiment and the modification described above. Further, according to the twelfth modification, the number of parts of the deflection layer 74 can be reduced by configuring the deflection layer 74 with a prism.

(13th modification)
FIG. 19 is a longitudinal sectional view showing a craze-type deflection layer 74 as the double window 1 according to the thirteenth modification. As shown in FIG. 19, the deflection layer 74 of the thirteenth modification is a craze mode. The term “craze” (sometimes referred to as “craze”) refers to a substantially linear crack or crack formed in a resin film. In particular, the craze in the thirteenth modified example is one in which resin fibrils (that is, fibrous resin) remain between the wall surfaces of cracks or cracks formed in the resin film, and no resin fibrils remain. It is different from a crack.

As shown in FIG. 19, the deflection layer 74 of the thirteenth modification has a main body portion 7410 made of a resin film and a plurality of crazes 7411 formed on the surface 7410 a on the outdoor 2 side of the main body portion 7410.

The craze 7411 is, for example, a straight plate with a sharp tip such as a blade or blade, and can be obtained by imparting a minute bending deformation along the straight line to the resin film.

In the double window 1 of the thirteenth modified example, the visible light L3 incident on the craze 7411 of the deflecting layer 74 travels in the craze 7411 and then the resin fibril 7411a (that is, the high refractive index layer). It is incident on the gap 7411b (that is, the low refractive index layer). In FIG. 19, only one gap 7411b is representatively shown. When the incident angle of the visible light L3 to the gap 7411b is larger than the critical angle, the visible light L3 is totally reflected by the gap 7411b and travels toward the indoor 3 side. Since the visible light L3 is totally reflected by the plurality of randomly arranged gaps 7411b, the visible light L3 is emitted at various angles. Therefore, it can be expected that the deflection layer 74 has a light diffusion function and suppresses glare.

Also in the thirteenth modification, similarly to the double window 1 of the above-described embodiment and modification, the illumination effect of the light taken in can be improved by reducing the direct light by the deflection layer 74. Further, according to the thirteenth modification, the number of parts of the deflection layer 74 can be reduced by configuring the deflection layer 74 with crazes.

(14th modification)
FIG. 20 is a longitudinal sectional view showing a mirror louver type deflection layer 74 as the double window 1 according to the fourteenth modification. The deflection layer 74 of the twelfth modification has a plurality of blades 7415 arranged at intervals in the vertical direction d3. Each blade 7415 deflects the visible light L3 toward the indoor 3 side by specularly reflecting the visible light L3 on its upper surface 7415a. The deflection layer 74 shown in FIG. 20 is prepared by preparing a transparent base material with a cut 7416 and then filling the transparent base cut 7416 with a high reflectivity material such as aluminum. obtain. In the deflection layer 74 obtained by this method, the upper surface 7415a of the blade 7415 is formed of a high reflectivity material such as aluminum. As another example, the blade 7415 may be formed as a gap. In this example, total reflection due to the difference in refractive index between the transparent substrate and the blade 7415 made of a gap can be caused, and a deflection function that does not cause reflection loss due to total reflection can be expected.

Also in the fourteenth modification, similarly to the double window 1 in the embodiment and the modification described above, it is possible to improve the illumination effect of the light taken in while avoiding direct light by the deflection layer 74.

(15th modification)
FIG. 21 is a longitudinal sectional view showing an example in which an angle-dependent light control sheet 7420 is arranged on the indoor 3 side of the deflection layer 74 as the double window 1 according to the fifteenth modification. As shown in FIG. 21, in the fifteenth modification, a deflection layer 74 is laminated on the outer window 5, and an angle-dependent light control sheet 7420 is laminated on the inner window 6. The angle-dependent light control sheet 7420 selectively scatters only incident light from a predetermined angle range and transmits other incident light.

The angle-dependent light control sheet 7420, for example, maintains a resin composition containing at least two types of photopolymerizable oligomers or monomers in a film form, and cures the film form body by irradiating ultraviolet rays from a predetermined direction. You may form by doing.

The angle-dependent light control sheet 7420 of the fifteenth modified example has an optical characteristic of scattering the visible light L3 incident from obliquely above at an angle of a predetermined angle or more. Further, the angle-dependent light control sheet 7420 has an optical characteristic of transmitting visible light incident from obliquely above at an angle less than a predetermined angle, visible light incident from the horizontal direction, and visible light incident from obliquely below.

Among the visible light L3 incident on the deflection layer 74, the visible light L3 not incident on the steep slope 742b or the gentle slope 742c (see FIG. 3A) can travel obliquely downward toward the indoor 3 side. The visible light L3 traveling obliquely downward may become glare and feel dazzling.

However, in the fifteenth modification, the visible light L3 traveling obliquely downward can be scattered by the angle-dependent light control sheet 7420. Thereby, the glare resulting from the visible light L3 which progresses diagonally downward can be suppressed.

Also in the fifteenth modification, similarly to the double window 1 in the embodiment and the modification described above, the illumination effect of the light taken in while avoiding direct light can be improved by the deflection layer 74. Further, the glare can be suppressed by scattering the visible light L3 that could not be appropriately deflected by the deflection layer 74 by the angle-dependent light control sheet 7420.

(16th modification)
FIG. 22 is a longitudinal sectional view showing an example in which the deflection layer 74 is reinforced as the double window 1 according to the sixteenth modification. As shown in FIG. 22, in the sixteenth modification, the outer peripheral edge of the light control sheet 70, that is, the deflection layer 74 is covered with the covering material 151, and the outer peripheral edges of the light control sheet 70 and the windows 5 and 6 are window frames. 81, 82. The covering material 151 is formed of, for example, a silicone resin, an acrylic resin, a urethane resin, a polysulfide resin, and a mixture thereof. The covering material 151 may be disposed not only to cover the boundary between the substrate and the deflection layer 74 but also to run on the deflection layer 74.

FIG. 22 shows a mode in which the end portion of the deflection layer 74 is accommodated in the window frames 81 and 82. However, this modification is not limited to this. When the deflection layer 74 is attached to the existing outer window 5 and inner window 6 later, the end of the deflection layer 74 may not be accommodated in the window frames 81 and 82. In this case, the boundary between the substrate and the deflection layer 74 can be covered by disposing the covering material 151 along the periphery of the deflection layer 74 so as to cover the boundary between the substrate and the deflection layer 74.

According to the sixteenth modified example, the coating material 151 can suppress the intrusion of moisture, foreign matter, and the like into the deflection layer 74, so that the deterioration of the deflection layer 74 and the peeling of the deflection layer 74 can be suppressed.

The aspects of the present invention are not limited to the individual embodiments described above, but include various modifications that can be conceived by those skilled in the art, and the effects of the present invention are not limited to the contents described above. That is, various additions, modifications, and partial deletions can be made without departing from the concept and spirit of the present invention derived from the contents defined in the claims and equivalents thereof.
