[0008] <1. First Embodiment> The following describes a light-shielding shield 1 according to the first embodiment of this disclosure with reference to the drawings. In this specification and in each drawing, elements similar to those already described are denoted by the same reference numerals, and detailed descriptions are not repeated.
[0009] (1.1. Usage status of light-blocking shield 1) Referring to Figure 1, the usage state of the light-shielding shield 1 according to the embodiment will be described. Figure 1 is a diagram showing an example of the usage state of the light-shielding shield 1 according to the first embodiment, where Figure 1A is a front view of the usage state and Figure 1B is a top view of the usage state.
[0010] As shown in Figure 1A, the light-shielding shield 1 is used by being placed on the upper surface of outdoor structures such as pergolas 100 installed in parks and various outdoor spaces. In recent years, particularly in urban areas, extreme heat has persisted during the summer. One of the causes of this is the generation of radiant heat, which is emitted into the surroundings when the surface temperature of an object rises due to the heating of the material by sunlight.
[0011] When sunlight shines on the surface of the light-shielding shield 1, the reflective member 20, described later, promotes the reflection of infrared rays, reducing the effects of radiant heat. In other words, outdoor structures equipped with the light-shielding shield 1 have their surface temperature suppressed by the shield, thus suppressing the temperature rise caused by radiant heat from sunlight inside indoor structures where people are located. The light-shielding shield 1 is particularly effective in the summer. Furthermore, the light-shielding shield 1 is removable and may be installed on outdoor structures only during seasons when it is particularly needed, such as in the summer.
[0012] As shown in FIG. 1B, the light-shielding shield 1 has a rectangular shape with a long side and a short side in plan view. In the following description, the direction along the long side of the light-shielding shield 1 is referred to as the long side direction X (an example of the first direction), the direction along the short side of the light-shielding shield 1 is referred to as the short side direction Y (an example of the second direction), and the direction along the thickness of the light-shielding shield 1 is referred to as the thickness direction Z.
[0013] In the illustrated example, the light-shielding shield 1 is arranged in accordance with the movement of the sun. Specifically, it is preferable that the light-shielding shield 1 is arranged such that the long side direction X is along the east-west direction and the short side is along the north-south direction. By arranging it in this way, even in the time zone when the sun is located in the east or west and the angle of sunlight becomes low, a light-shielding space located below the light-shielding shield 1 can be secured as wide as possible. The specific structure of such a light-shielding shield 1 will be described below.
[0014] (1.2. Structure of the light-shielding shield 1 and members) FIG. 2 is a diagram showing the light-shielding shield 1 according to the first embodiment, and FIG. 2A is a plan view of the light-shielding shield 1. As shown in FIG. 2A, the light-shielding shield 1 includes a metal mesh 10, a plurality of reflective members 20 made of metal foil attached to the mesh 10, and a frame member 30 covering the outside of the mesh 10. The structures of the mesh 10 and the reflective member 20 will be described with reference to FIG. 3.
[0015] FIG. 3 is a diagram showing each member of the light-shielding shield 1 shown in FIG. 2. FIG. 3A is a plan view of the mesh 10, and FIG. 3B is a cross-sectional view taken along line B-B in FIG. 3A. As shown in FIGS. 3A and 3B, the mesh 10 has a rectangular shape with a long side and a short side in plan view. The mesh 10 has a plurality of cross members 11 extending along either the long side direction X or the short side direction Y that are perpendicular to each other, and as a whole, it has a grid-like shape. In the illustrated example, the plurality of cross members 11 have a rectangular grid shape in plan view, but the plurality of cross members 11 may have a square grid shape.
[0016] The plurality of rack members 11 have a plurality of horizontal racks 11A extending along the long side direction X and a plurality of vertical racks 11B extending along the short side direction Y. The horizontal racks 11A and the vertical racks 11B are arranged perpendicular to each other, and the intersecting portions are connected. The horizontal racks 11A and the vertical racks 11B are made of metal wire.
[0017] Figure 3C is a plan view of the reflecting member 20. The reflecting member 20 shown in Figure 3C is composed of, for example, the following materials. · Aluminum foil with an aluminum component ratio of 99.3% or more, a foil thickness of 15 μm, and a shiny surface · The back surface is processed with polyethylene. That is, the reflecting member 20 preferably has a material with a high reflectivity to infrared rays. The reflectivity is a physical quantity representing the strength of light reflection by a substance.
[0018] In other words, the reflecting member 20 preferably has a material with a low emissivity. The emissivity is a physical quantity representing the strength of thermal radiation emitted by a substance. Generally, it is known that when the reflectivity is high, the emissivity is low. Specifically, the material, component ratio, and gloss affect the emissivity and reflectivity. For example, aluminum foil with a shiny surface has a high reflectivity and a low emissivity due to its gloss. Note that the reflecting member 2 of the reflecting member 20 may be a metal foil material other than aluminum. This is because metal foil has a high reflectivity and a low emissivity compared to non-metallic materials. Next, the attachment state of the reflecting member 20 to the mesh 10 will be described.
[0019] Figure 2B is a cross-sectional view taken along line A-A in Figure 2A. As shown in Figure 2B, in the light-shielding shield 1, the reflecting member 20 extends along the long side direction X and extends in a zigzag shape while bending when viewed from the short side direction Y. The reflecting member 20 is connected in the long side direction X so as to alternately straddle adjacent vertical racks 11B from one side and the other side in the thickness direction Z. Further, as shown in Figure 2A, a plurality of reflecting members 20 are provided for each region partitioned by the horizontal racks 11A. In the illustrated example, six reflecting members 20 are attached to the mesh 10. Note that the quantity of the reflecting members 20 can be arbitrarily selected.
[0020] Furthermore, the two reflective members 20 adjacent to each other in the short-side direction Y have different phases of their periods during bending. This point will be explained in detail using Figures 2B and 2C. Figure 2C is a cross-sectional view taken along the line A'-A' in Figure 2A. That is, Figures 2B and 2C are front views of each of the two reflective members 20 adjacent to each other in the short-side direction Y, as seen from the short-side direction Y. In the following explanation, the phase corresponding to one period will be described as 360°.
[0021] As shown in Figures 2B and 2C, the reflective member 20 located on line AA and the reflective member 20 located on line A'-A' have different phases in the period of bending in the thickness direction Z when viewed from the front. In the illustrated example, the phases of the two reflective members 20 adjacent to each other in the short side direction Y are 180° apart. By making the phases of the two reflective members 20 adjacent to each other in the short side direction Y different in this way, a gap is formed between them in the short side direction Y. In addition, by making the phases different, the surfaces of the reflective members 20 will face in various directions.
[0022] Note that the phases of two adjacent reflective members 20 in the short-side direction Y may differ from each other by an angle other than 180°, such as 90°. Also, in the illustrated example, the phases of two adjacent reflective members 20 in the short-side direction Y differ by a uniform 180°, but this is not limited to this. In other words, the phase difference between two adjacent reflective members 20 in the short-side direction Y may differ depending on their position.
[0023] (1.3.Summary) As described above, the light-shielding shield 1 in this disclosure comprises a mesh 10 and a reflective member 20 made of metal foil attached to the mesh 10. Therefore, it is possible to effectively reduce the effects of radiant heat from sunlight with a simple and inexpensive configuration. Furthermore, if the mesh 10 is formed of metal wires exhibiting a grid pattern and the reflective member 20 is formed of aluminum foil, the light-shielding shield can be made lightweight. In addition, the reflective member 20 extends along the long side direction X and extends in a zigzag shape while bending when viewed from the short side direction Y. Therefore, the surface of the reflective member 20 in the light-shielding shield 1 can be angled to promote light reflection and airflow.
[0024] Furthermore, in the light-shielding shield 1 of this disclosure, multiple reflective members 20 are provided for each region partitioned by the horizontal bars 11A. This makes it possible to reduce the size of the reflective members 20 and to procure the metal foil material for the reflective members 20 more easily compared to a configuration in which, for example, the reflective members 20 are made from a single piece of metal foil and the mesh 10 is covered integrally with the single reflective member 20. In addition, gaps are formed between the multiple reflective members 20, creating airflow and suppressing the rise in the surface temperature of the reflective members 20.
[0025] Furthermore, in the light-shielding shield 1 of this disclosure, the two adjacent reflective members 20 have different phases in their bending period. As a result, the gap formed between the two adjacent reflective members 20 can be made larger, making it easier for air to flow between the two reflective members 20, and thus suppressing the rise in surface temperature of the light-shielding shield 1 due to radiant heat from sunlight. In addition, by making the phases of the two adjacent reflective members 20 different, it is possible to secure reflective surfaces with efficient angles for a wide range of irradiation angles for multiple reflective members 20 as the irradiation angle of sunlight changes over time.
[0026] Furthermore, since the mesh 10 is made of metal, a certain degree of rigidity can be given to the light-shielding shield 1. Also, since the reflective member 20 is made of aluminum foil, sunlight can be efficiently reflected, and the effects of radiant heat can be effectively reduced.
[0027] <2. Second Embodiment> Next, the structure of the light-shielding shield 2 according to the second embodiment will be described with reference to Figures 4 and 5. Note that components similar to those in the first embodiment are denoted by the same reference numerals, and repeated explanations are omitted.
[0028] Figure 4 shows a light-shielding shield 2 according to the second embodiment, where Figure 4A is a plan view of the light-shielding shield 2 and Figure 4B is a cross-sectional view along line C in Figure 4A. As shown in Figures 4A and 4B, the light-shielding shield 2 according to the second embodiment comprises a first mesh 10A and a second mesh 10B arranged at intervals in the thickness direction Z. In other words, the light-shielding shield 2 has a two-layer structure.
[0029] As shown in Figure 4B, the first mesh 10A is positioned on the upper side (front side) in the thickness direction Z. The second mesh 10B is positioned on the lower side (back side) in the thickness direction Z. The first mesh 10A and the second mesh 10B are identical in shape and size in the long side direction X and the short side direction Y. In the illustrated example, the phases of the bending periods are different for the reflective members 20 attached to the first mesh 10A and the second mesh 10B, respectively.
[0030] In the second embodiment, the light-shielding shield 2 further includes a separation member 12. The separation member 12 is installed between the first mesh 10A and the second mesh 10B in the thickness direction Z. The separation member 12 separates the first mesh 10A and the second mesh 10B in the thickness direction Z. The structure of the separation member 12 will be described in detail with reference to Figure 5.
[0031] Figure 5 shows an example of the separation member 12 in Figure 4B, and Figure 5A is an enlarged view of section P in Figure 4B. As shown in Figure 5A, a pair of grooves 12C are formed in the center of the short side direction Y on the periphery of the separation plate 12A, recessed inward in the thickness direction Z. The separation plate 12A is positioned so that the crossbars 11A are fitted into the inside of each of the pair of grooves 12C. This prevents misalignment of the separation plate 12A in the long side direction X and the short side direction Y. Since the crossbars 11A are in contact with the bottom of the grooves 12C in the separation member 12, each crossbar 11A cannot get any closer in the thickness direction Z. In other words, the first mesh 10A and the second mesh 10B are restricted (separated) from getting too close to each other in the thickness direction Z.
[0032] Figure 5B is a view taken along arrow D in Figure 5A. As shown in Figure 5B, the separation member 12 is composed of two separation plates 12A. The two separation plates 12A are spaced apart from each other at both ends in the thickness direction Z, sandwiching the vertical support 11B and the cushioning material 12B, and are connected to the vertical support 11B by adhesive and bolts 14. This positions the separation member 12 relative to the first mesh 10A and the second mesh 10B.
[0033] In the illustrated example, as shown in Figure 4B, two separation members 12 are arranged with a gap in the long side direction X, but depending on the arrangement, the two separation members 12 may be arranged with a gap in the short side direction Y. The number, arrangement position, and orientation of the separation members 12 can be arbitrarily set according to the size of the first mesh 10A and the second mesh 10B and the bending stiffness in the thickness direction Z.
[0034] Furthermore, as shown in Figure 4B, a square pipe 40 is positioned between the first mesh 10A and the second mesh 10B, extending along the short side Y at the center of the long side X. The square pipe 40 is made of, for example, aluminum. This further increases the rigidity of the first mesh 10A and the second mesh 10B. In the illustrated example, the square pipe 40 is shown positioned at the center of the long side X, but this is not limited to this configuration. That is, the position, extension direction, and number of square pipes 40 can be arbitrarily changed according to the size of the light-shielding shield 2 or the positional relationship of other components. Also, as shown in Figure 4B, the light-shielding shield 2 is equipped with a fixing member 13. The structure of the fixing member 13 will be described later (see Figure 7).
[0035] As described above, the light-shielding shield 2 according to the second embodiment comprises a first mesh 10A and a second mesh 10B, each with a reflective member 20 attached. By stacking the mesh 10 and the reflective member 20 in the thickness direction Z in this way, the shielding effect against radiant heat can be enhanced.
[0036] Furthermore, the light-shielding shield 2 according to the second embodiment includes a separating member 12 that separates the first mesh 10A and the second mesh 10B in the thickness direction Z. Therefore, in the first mesh 10A and the second mesh 10B which are arranged so that the thickness direction Z is vertical, the deflection of the light-shielding shield 2 can be prevented so that the upper first mesh 10A does not bend.
[0037] <3. Third Embodiment> Next, the structure of the light-shielding shield 3 according to the third embodiment will be described with reference to Figures 6 and 7. Note that components similar to those in any of the embodiments described above are denoted by the same reference numerals, and repeated explanations are omitted.
[0038] Figure 6 shows a light-shielding shield 3 according to the third embodiment, and Figure 6A is a plan view of the light-shielding shield 3. As shown in Figure 6A, the light-shielding shield 3 according to the third embodiment includes a frame member 30 that covers the periphery of the first mesh 10A and the second mesh 10B from the outside in the long side direction X and the short side direction Y. The frame member 30 has a rectangular shape with a long side and a short side in plan view, and encloses the first mesh 10A and the second mesh 10B inside. The frame member 30 includes a pair of horizontal frames 30A along the long side direction X and a pair of vertical frames 30B along the short side direction Y.
[0039] Figure 6B is a cross-sectional view along line EE in Figure 6A. As shown in Figure 6B, the horizontal frame 30A has a U-shape with a cross-section that opens inward in the direction of the long side, and the ends of the first mesh 10A and the second mesh 10B in the direction of the long side X are housed inside. Although not shown, the vertical frame 30B has a similar configuration. That is, the vertical frame 30B has a U-shape with a cross-section that opens inward in the direction of the short side Y, and the ends of the first mesh 10A and the second mesh 10B in the direction of the short side Y are housed inside.
[0040] In this embodiment, the reflective member 20 extends in a zigzag pattern, bending alternately to straddle the first mesh 10A and the second mesh 10B, which are spaced apart in the thickness direction Z. In other words, the reflective member 20 is attached to the first mesh 10A and the second mesh 10B by weaving between the vertical struts 11B that are adjacent to each other in the long side direction X, while being spaced apart in the thickness direction Z.
[0041] The light-shielding shield 3 according to the third embodiment includes a fixing member 13. The fixing member 13 is positioned inside the frame member 30 and fixes the ends of the first mesh 10A and the second mesh 10B to the frame member 30. Figure 6B shows the fixing member 13 inside the vertical frame 30B, fixing the ends of the first mesh 10A and the second mesh 10B in the long side direction X to the vertical frame 30B. On the other hand, the fixing member 13 is similarly positioned inside the horizontal frame 30A and fixes the ends of the first mesh 10A and the second mesh 10B in the short side direction Y to the horizontal frame 30A.
[0042] Figure 7 shows an example of the fixing member 13 in Figure 6B, and Figure 7A is an enlarged view of section Q in Figure 6B. As shown in Figure 7A, the fixing member 13 consists of a U-shaped fixing plate 13A with a cross section that opens inward in the long side direction X, and bolts 14 that connect the fixing plate 13A to the inner surface of the frame member 30. A pair of bent portions 13B are formed at the end of the fixing plate 13A. The fixing member 13 is connected to the inner surface of the vertical frame 30B with the bent portions 13B engaged with the vertical struts 11B. In this way, the first mesh 10A and the second mesh 10B are fixed to the vertical frame 30B by the fixing member 13. Although not shown, the fixing plate 13A housed inside the horizontal frame 30A is connected to the inner surface of the horizontal frame 30A with the bent portions 13B engaged with the horizontal struts 11A.
[0043] Figure 7B is a view from arrow F in Figure 7A. As shown in Figure 7B, a pair of slits 13C are formed in the central part of the periphery of the fixing plate 13A. The fixing member 13 is attached to the frame member 30 such that the horizontal bar 11A is fitted inside the pair of slits 13C. This makes it possible to suppress displacement of the fixing plate 13A in the short side direction Y. The number, position, and orientation of the fixing members 13 can be arbitrarily changed according to the size of the light-shielding shield 2 or the positional relationship of other components.
[0044] As described above, in the third embodiment of the light-shielding shield 3, the reflective member 20 extends in a zigzag shape, bending alternately to straddle the first mesh 10A and the second mesh 10B. Therefore, the angle of the reflective member 20 can be set according to the distance Z in the thickness direction between the first mesh 10A and the second mesh 10B, and by securing a large light-shielding surface of the reflective member 20 when sunlight is irradiated, light-shielding efficiency can be ensured.
[0045] Furthermore, the light-shielding shield 3 according to the third embodiment includes a fixing member 13. This allows the first mesh 10A and the second mesh 10B to be fixed to the frame member 30, preventing the first mesh 10A and the second mesh 10B from shifting relative to the frame member 30.
[0046] <4. Fourth Embodiment> Next, the structure of the light-shielding shield 4 according to the fourth embodiment will be described with reference to Figures 8 and 9. Note that components similar to those in any of the embodiments described above are denoted by the same reference numerals, and repeated explanations are omitted.
[0047] Figure 8 shows the surface of the light-shielding shield 4 according to the fourth embodiment, where Figure 8A is a plan view of the surface of the light-shielding shield 1. Figure 8B is a cross-sectional view taken along the GG line in Figure 8A. As shown in Figures 8A and 8B, the reflective member 20 in the light-shielding shield 4 according to the fourth embodiment comprises a first reflective member 20A and a second reflective member 20B.
[0048] The first reflective members 20A are attached to the first mesh 10A located on the surface, extend along the long side direction X, and are arranged in multiples in the short side direction Y. The first reflective members 20A extend in a zigzag pattern while bending within the first mesh 10A. The phase of the bending period coincides among multiple reflective members 20 adjacent to each other in the short side direction Y.
[0049] Figure 9 shows the back surface of the light-shielding shield 4 shown in Figure 8, and Figure 9A is a plan view of the back surface of the light-shielding shield 4. Figure 9B is a cross-sectional view taken along line HH in Figure 9A. As shown in Figures 9A and 9B, the second reflective members 20B are attached to the first mesh 10A and the second mesh 10B, extending along the short side direction Y and arranged in multiples in the long side direction X.
[0050] As shown in Figure 9B, the second reflective member 20B extends in a zigzag pattern, bending alternately to straddle the first mesh 10A and the second mesh 10B. In other words, the second reflective member 20B is attached to the first mesh 10A and the second mesh 10B by weaving between the horizontal bars 11A that are adjacent to each other in the short side direction Y, while being spaced apart in the thickness direction Z. Note that the second reflective member 20B may be attached only to the second mesh 10B.
[0051] As described above, in this embodiment, the light-shielding shield 4 has a first reflective member 20A attached to the first mesh 10A that extends along the long side direction X, and a second reflective member 20B mainly attached to the second mesh 10B that extends along the short side direction Y.
[0052] Furthermore, in the light-shielding shield 4 according to this embodiment, the first reflective member 20A extends in a zigzag pattern while bending in the first mesh 10A, and the second reflective member 20B extends in a zigzag pattern while bending so as to alternately straddle the first mesh 10A and the second mesh 10B. As a result, the gap formed between the first reflective member 20A and the second reflective member 20B is further enlarged, and the airflow between the first mesh 10A and the second mesh 10B can be increased even further. This is expected to more effectively suppress the rise in surface temperature of the first reflective member 20A and the second reflective member 20B.
[0053] <5. Other uses> Next, other uses of the shading shields 1-4 in this disclosure will be described with reference to Figures 10 to 12. Figure 10 is a diagram showing other examples of use, with Figure 10A showing a first example of use and Figure 10B showing a second example of use. As shown in Figure 10A, the shading shields 1-4 may be placed on the roof of the workshop 200. Alternatively, as shown in Figure 10B, the shading shield 1 may be suspended in the attic of the ceiling of the house 300. Since the shading shields 1-4 have the function of suppressing the transfer of radiant heat, they can achieve their effect.
[0054] Figure 11 shows other examples of use, with Figure 11A showing a third example of use and Figure 11B showing a fourth example of use. As shown in Figure 11A, the shading shields 1 to 4 may be placed both above the ceiling and in the attic of the house 400. In this case, a higher radiant heat shielding effect can be expected compared to when they are placed either above the ceiling or in the attic. Also, as shown in Figure 11B, the shading shields 1 to 4 may be applied to the ceiling and above the interior of a structure where animals are exclusively located, such as a livestock barn 500. In this case, the shading shields 1 to 4 may be laid above the interior in a manner that they are suspended from the ceiling.
[0055] Figure 12 shows other examples of use, with Figure 12A showing a fifth example of use and Figure 12B showing a sixth example of use. As shown in Figure 12A, the shading shields 1-4 may be attached to the roof of the fish farm's cages 600. Alternatively, as shown in Figure 12B, the shading shields 1-4 may be applied inside the cultivation house 700.
[0056] In other words, the extreme heat of recent summers is having serious consequences not only in urban areas but also in rural areas. These consequences extend to various fields that are heavily influenced by the natural environment, such as agriculture, fisheries, and livestock farming. Therefore, it is expected that applying the light-shielding shields 1 to 4 described in this disclosure to various fields will help mitigate such serious impacts.
[0057] <6. Other variations> Although the configurations of the light-shielding shields 1 to 4 according to the first to fourth embodiments have been described above, the application of the technical concept of this disclosure is not limited to the above embodiments.
