Mode for Carrying Out the Invention

[0008] <1. First Embodiment> Hereinafter, the light-shielding shield 1 according to the first embodiment of the present disclosure will be described with reference to the drawings. In the present specification and each figure, the same elements as those already described are denoted by the same reference numerals, and detailed descriptions will not be repeated.

[0009] (1.1. Usage state of the light-shielding shield 1) With reference to FIG. 1, the usage state of the light-shielding shield 1 according to the embodiment will be described. FIG. 1 is a diagram showing an example of the usage state of the light-shielding shield 1 according to the first embodiment, FIG. 1A is a front view of the usage state, and FIG. 1B is a plan view of the usage state.

[0010] As shown in FIG. 1A, the light-shielding shield 1 is disposed and used on the upper surface of an outdoor structure such as a pergola 100 laid in a park or various outdoor spaces. In recent years, especially in summer, severe heat has continued mainly in urban areas. The causes include the generation of radiant heat in which the surface temperature of an object rises due to the heating of the substance by sunlight and is radiated to the surroundings.

[0011] When sunlight irradiates the surface of the light-shielding shield 1, the action of a reflection member 20 described later promotes the reflection of infrared rays and reduces the influence of radiant heat. That is, the outdoor structure provided with the light-shielding shield 1 can suppress the rise in the surface temperature by the light-shielding shield, so that the rise in temperature due to radiant heat from sunlight can be suppressed with respect to the inside of the indoor structure where people are located. The light-shielding shield 1 particularly exhibits its effect in summer. Further, the light-shielding shield 1 is detachably attached and may be installed on the outdoor structure only in seasons when it is particularly necessary, such as 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 ensured to be maximally wide. 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 view 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 view 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 presents a grid-like shape. In the illustrated example, the plurality of cross members 11 present a rectangular grid shape in plan view, but the plurality of cross members 11 may present 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 orthogonally 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 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 straddle adjacent vertical racks 11B alternately from one side and the other side in the thickness direction Z. Also, 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] And, the two reflecting members 20 adjacent to each other in the short side direction Y have different phases of the cycle in the bending. This will be described in detail with reference to FIGS. 2B and 2C. FIG. 2C is a cross-sectional view taken along line A'-A' in FIG. 2A. That is, FIGS. 2B and 2C are front views of the two reflecting members 20 adjacent to each other in the short side direction Y as viewed from the short side direction Y. In the following description, the phase corresponding to one cycle is described as 360°.

[0021] As shown in FIGS. 2B and 2C, the reflecting member 20 located on line A-A and the reflecting member 20 located on line A'-A' have different phases of the cycle of bending in the thickness direction Z in the front view. In the illustrated example, the phases of the two reflecting members 20 adjacent to each other in the short side direction Y are different by 180°. By making the phases of the two reflecting members 20 adjacent to each other in the short side direction Y different in this way, a gap formed between the two in the short side direction Y is formed. Also, by making the phases different, the surfaces of the reflecting members 20 will face various directions.

[0022] Note that the phases of the two reflecting members 20 adjacent to each other in the short side direction Y may be different from each other at an angle other than 180°, such as 90°. Also, in the illustrated example, among the plurality of reflecting members 20, the phases of the two reflecting members 20 adjacent to each other in the short side direction Y are uniformly different by 180° each, but this is not the case. That is, among the plurality of reflecting members 20, the phase shift between the two reflecting members 20 adjacent to each other in the short side direction Y may be different depending on the position.

[0023] (1.3. Small parenthesis) As described above, the light-shielding shield 1 in the present disclosure includes a mesh 10 and a reflective member 20 made of a metal foil attached to the mesh 10. Therefore, with a simple and low-cost configuration, the influence of radiant heat from sunlight can be effectively reduced. Further, when the mesh 10 is formed of a metal wire material having a grid shape and the reflective member 20 is formed of an aluminum foil, the light-shielding shield can have a lightweight configuration. Further, 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, in the light-shielding shield 1, the surface of the reflective member 20 can be angled to promote light reflection and air flow.

[0024] Further, in the light-shielding shield 1 of the present disclosure, a plurality of reflective members 20 are provided for each region partitioned by the horizontal bars 11A. Thereby, for example, compared with a configuration in which the reflective member 20 is covered with a single metal foil and the mesh 10 is integrally covered with a single reflective member 20, the size of the reflective member 20 can be suppressed, and the procurement of the material of the metal foil that becomes the reflective member 20 can be facilitated. Further, a gap is formed between the plurality of reflective members 20 to create an air flow and suppress an increase in the surface temperature of the reflective member 20.

[0025] Further, in the light-shielding shield 1 of the present disclosure, the phases of the periods in the bending of two adjacent reflective members 20 are different from each other. Therefore, the gap formed between two adjacent reflective members 20 can be enlarged, an air flow is likely to occur between the two reflective members 20, and an increase in the surface temperature of the light-shielding shield 1 due to the radiant heat of sunlight can be suppressed. Further, by making the phases of two adjacent reflective members 20 different from each other, a plurality of reflective members 20 can secure reflective surfaces at efficient angles for a wide range of irradiation angles while the irradiation angle of sunlight changes over time.

[0026] In addition, since the mesh 10 is formed of a metallic material, a certain rigidity can be imparted to the light-shielding shield 1. Further, since the reflecting member 20 is formed of an aluminum foil, sunlight can be efficiently reflected, and the influence of radiant heat can be effectively reduced.

[0027] <2. Second Embodiment> Next, with reference to FIGS. 4 and 5, the structure of the light-shielding shield 2 according to the second embodiment will be described. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and repeated descriptions thereof will be omitted.

[0028] FIG. 4 is a view showing the light-shielding shield 2 according to the second embodiment, FIG. 4A is a plan view of the light-shielding shield 2, and FIG. 4B is a cross-sectional view taken along line C-C in FIG. 4A. As shown in FIGS. 4A and 4B, in the light-shielding shield 2 according to the second embodiment, the mesh 10 includes a first mesh 10A and a second mesh 10B that are arranged at intervals in the thickness direction Z. That is, the light-shielding shield 2 has a two-layer structure.

[0029] As shown in FIG. 4B, the first mesh 10A is arranged on the upper side (front surface side) in the thickness direction Z. The second mesh 10B is arranged on the lower side (back surface side) in the thickness direction Z. The first mesh 10A and the second mesh 10B are identical in shape and size to each other in the long side direction X and the short side direction Y. In the illustrated example, the phases of the periods in the bending are different from each other between the reflecting 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 separating member 12. The separating member 12 is attached between the first mesh 10A and the second mesh 10B in the thickness direction Z. The separating member 12 separates the first mesh 10A and the second mesh 10B in the thickness direction Z. The structure of the separating member 12 will be described in detail with reference to FIG. 5.

[0031] FIG. 5 is a view showing an example of the separation member 12 in FIG. 4B, and FIG. 5A is an enlarged view of the P portion in FIG. 4B. As shown in FIG. 5A, a pair of grooves 12C that are recessed inward in the thickness direction Z are formed at the central portion of the short side direction Y at the peripheral edge of the separation plate 12A. The separation plate 12A is arranged so that the horizontal crossbar 11A is fitted into each of the pair of grooves 12C. Therefore, it is possible to prevent displacement in the long side direction X and the short side direction Y of the separation plate 12A. And since the horizontal crossbar 11A contacts the bottom of the groove 12C in the separation member 12, each horizontal crossbar 11A will not approach further in the thickness direction Z. That is, the regulation (separation) that the first mesh 10A and the second mesh 10B approach each other in the thickness direction Z is achieved.

[0032] FIG. 5B is a view seen from the direction of arrow D in FIG. 5A. As shown in FIG. 5B, the separation member 12 is composed of two separation plates 12A. The two separation plates 12A are arranged at both ends in the thickness direction Z with a space between them so as to sandwich the vertical crossbar 11B and the buffer material 12B, and are connected to the vertical crossbar 11B by an adhesive and bolts 14. Thereby, the positioning of the separation member 12 with respect to the first mesh 10A and the second mesh 10B is achieved.

[0033] In the illustrated example, as shown in FIG. 4B, two separation members 12 are arranged at intervals in the long side direction X, but depending on the arrangement position, two separation members 12 may be arranged at intervals in the short side direction Y. The quantity, arrangement position, and orientation of the separation members 12 can be arbitrarily set according to the sizes of the first mesh 10A and the second mesh 10B and the bending rigidity in the thickness direction Z.

[0034] Also, as shown in FIG. 4B, between the first mesh 10A and the second mesh 10B, the square pipe 40 is arranged to extend along the short side direction Y at the central part in the long side direction X. The square pipe 40 is formed of, for example, an aluminum material. Thereby, the rigidity of the first mesh 10A and the second mesh 10B can be further enhanced. In the illustrated example, the configuration in which the square pipe 40 is arranged at the central part in the long side direction X is shown, but this is not the only case. That is, the arrangement position, the extending direction, and the quantity of the square pipe 40 can be arbitrarily changed according to the situation such as the size of the light shielding shield 2 or the positional relationship of other components. Also, as shown in FIG. 4B, the light shielding shield 2 includes a fixing member 13. The structure of the fixing member 13 will be described later (see FIG. 7).

[0035] As described above, the light shielding shield 2 according to the second embodiment includes the first mesh 10A and the second mesh 10B, and the reflecting members 20 are attached to each of them. In this way, by laminating the mesh 10 and the reflecting member 20 in the thickness direction Z, the shielding effect of radiant heat can be enhanced.

[0036] Also, 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 arranged such that the thickness direction Z is the vertical direction, the deflection of the light shielding shield 2 can be prevented so that the first mesh 10A located above does not bend.

[0037] <3. Third Embodiment> Next, with reference to FIGS. 6 and 7, the structure of the light shielding shield 3 according to the third embodiment will be described. Regarding the same configurations as those in any of the above-described embodiments, the same reference numerals will be given and repeated descriptions will be omitted.

[0038] FIG. 6 is a view showing a light-shielding shield 3 according to the third embodiment, and FIG. 6A is a plan view of the light-shielding shield 3. As shown in FIG. 6A, the light-shielding shield 3 according to the third embodiment includes a frame member 30 that covers the peripheries 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 thereof. 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, respectively.

[0039] FIG. 6B is a cross-sectional view taken along line E-E in FIG. 6A. As shown in FIG. 6B, the horizontal frame 30A has a U-shaped cross-section that opens inward in the long-side direction, and the ends of the first mesh 10A and the second mesh 10B in the long-side direction X are respectively accommodated therein. Although not shown, the vertical frame 30B has the same configuration. That is, the vertical frame 30B has a U-shaped cross-section that opens inward in the short-side direction Y, and the ends of the first mesh 10A and the second mesh 10B in the short-side direction Y are respectively accommodated therein.

[0040] In the present embodiment, the reflecting member 20 extends in a zigzag shape while bending so as to straddle the first mesh 10A and the second mesh 10B arranged at intervals in the thickness direction Z. In other words, among the plurality of vertical bars 11B arranged side by side in the long-side direction X, the reflecting member 20 is connected so as to sew between the vertical bars 11B that are adjacent to each other in the long-side direction X while being separated from each other in the thickness direction Z, and is attached to the first mesh 10A and the second mesh 10B.

[0041] The light-shielding shield 3 according to the third embodiment includes a fixing member 13. The fixing member 13 is disposed inside the frame member 30 and fixes the end portions of the first mesh 10A and the second mesh 10B to the frame member 30, respectively. In FIG. 6B, inside the vertical frame 30B, a fixing member 13 that fixes the end portions in the long-side direction X of the first mesh 10A and the second mesh 10B to the vertical frame 30B is shown. On the other hand, the fixing member 13 is similarly disposed inside the horizontal frame 30A and fixes the end portions in the short-side direction Y of the first mesh 10A and the second mesh 10B to the horizontal frame 30A.

[0042] FIG. 7 is a view showing an example of the fixing member 13 in FIG. 6B, and FIG. 7A is an enlarged view of the Q portion in FIG. 6B. As shown in FIG. 7A, the fixing member 13 includes a fixing plate 13A having a U-shaped cross section that opens toward the inside in the long-side direction X, and a bolt 14 that connects the fixing plate 13A to the inner surface of the frame member 30. A pair of bent portions 13B are formed at the end portions of the fixing plate 13A. The fixing member 13 is configured such that the fixing plate 13A is connected to the inner surface of the vertical frame 30B in a state where the bent portion 13B is engaged with the vertical bar 11B. Thereby, 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 in a state where the bent portion 13B is engaged with the horizontal bar 11A.

[0043] FIG. 7B is a view seen from the F direction in FIG. 7A. As shown in FIG. 7B, a pair of slits 13C are formed at the central portion of the peripheral edge 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. Therefore, displacement of the fixing plate 13A in the short-side direction Y can be suppressed. Note that the number, the disposed position, and the 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 light-shielding shield 3 according to the third embodiment, the reflecting member 20 extends in a zigzag shape while bending so as to straddle the first mesh 10A and the second mesh 10B alternately. Therefore, the angle of the reflecting member 20 can be adjusted according to the distance in the thickness direction Z between the first mesh 10A and the second mesh 10B, and by ensuring a large light-shielding surface of the reflecting member 20 when sunlight is irradiated, the light-shielding efficiency can be ensured.

[0045] Further, the light-shielding shield 3 according to the third embodiment includes a fixing member 13. Therefore, the first mesh 10A and the second mesh 10B can be fixed to the frame member 30, and it is possible to prevent the first mesh 10A and the second mesh 10B from being displaced with respect to the frame member 30.

[0046] <4. Fourth Embodiment> Next, with reference to FIGS. 8 and 9, the structure of the light-shielding shield 4 according to the fourth embodiment will be described. Note that the same reference numerals are given to the same configurations as those in any of the above-described embodiments, and repeated descriptions will be omitted.

[0047] FIG. 8 is a view showing the surface of the light-shielding shield 4 according to the fourth embodiment, FIG. 8A is a plan view of the surface of the light-shielding shield 1, and FIG. 8B is a cross-sectional view taken along line G-G in FIG. 8A. As shown in FIGS. 8A and 8B, the reflecting member 20 in the light-shielding shield 4 according to the fourth embodiment includes a first reflecting member 20A and a second reflecting member 20B.

[0048] The first reflecting member 20A is attached to the first mesh 10A located on the surface, extends along the long side direction X, and a plurality of them are arranged side by side in the short side direction Y. The first reflecting member 20A extends in a zigzag shape while bending in the first mesh 10A. In a plurality of reflecting members 20 adjacent to each other in the short side direction Y, the phases of the bending periods coincide.

[0049] FIG. 9 is a view showing the back surface of the light-shielding shield 4 shown in FIG. 8, FIG. 9A is a plan view of the back surface of the light-shielding shield 4, and FIG. 9B is a cross-sectional view taken along line H-H in FIG. 9A. As shown in FIGS. 9A and 9B, the second reflecting member 20B is attached to the first mesh 10A and the second mesh 10B, extends along the short side direction Y, and a plurality of them are arranged side by side in the long side direction X.

[0050] As shown in FIG. 9B, the second reflecting member 20B extends in a zigzag shape while bending so as to straddle the first mesh 10A and the second mesh 10B alternately. In other words, the second reflecting member 20B is connected so as to sew between the horizontal bars 11A that are adjacent to each other in the short side direction Y while being spaced apart from each other in the thickness direction Z among the plurality of horizontal bars 11A arranged side by side in the short side direction Y, and is attached to the first mesh 10A and the second mesh 10B. Note that the second reflecting member 20B may be attached only to the second mesh 10B.

[0051] As described above, in the light-shielding shield 4 according to the present embodiment, the first reflecting member 20A attached to the first mesh 10A extends along the long side direction X, and the second reflecting member 20B mainly attached to the second mesh 10B extends along the short side direction Y.

[0052] Further, in the light-shielding shield 4 according to the present embodiment, the first reflecting member 20A extends in a zigzag shape while bending in the first mesh 10A, and the second reflecting member 20B extends in a zigzag shape while bending so as to straddle the first mesh 10A and the second mesh 10B alternately. Therefore, the gap formed between the first reflecting member 20A and the second reflecting member 20B can be further enlarged, and the air flow flowing between the first mesh 10A and the second mesh 10B can be further increased. As a result, it is expected that the rise in the surface temperature of the first reflecting member 20A and the second reflecting member 20B can be more effectively suppressed.

[0053] <5. Regarding Other Applications> Next, with reference to FIGS. 10 to 12, other uses of the light-shielding shields 1 to 4 in the present disclosure will be described. FIG. 10 is a diagram showing other usage examples, FIG. 10A is a diagram showing a first usage example, and FIG. 10B is a diagram showing a second usage example. As shown in FIG. 10A, the light-shielding shields 1 to 4 may be arranged on the roof of the workplace 200. Further, as shown in FIG. 10B, the light-shielding shield 1 may be suspended and arranged in the attic of the ceiling of the house 300. Since the light-shielding shields 1 to 4 have the function of suppressing the transmission of radiant heat, the effect can be achieved.

[0054] FIG. 11 is a diagram showing other usage examples, FIG. 11A is a diagram showing a third usage example, and FIG. 11B is a diagram showing a fourth usage example. As shown in FIG. 11A, the light-shielding shields 1 to 4 may be arranged on both the upper part of the ceiling and the attic in the house 400. In this case, a higher radiant heat shielding effect can be expected compared to the case where they are arranged on either the upper part of the ceiling or the attic. Further, as shown in FIG. 11B, the light-shielding shields 1 to 4 may be applied to the ceiling of a structure where animals are exclusively located, such as the livestock shed 500, and above the interior. In this case, the light-shielding shields 1 to 4 may be laid above the interior in a manner suspended from the ceiling.

[0055] FIG. 12 is a diagram showing other usage examples, FIG. 12A is a diagram showing a fifth usage example, and FIG. 12B is a diagram showing a sixth usage example. As shown in FIG. 12A, the light-shielding shields 1 to 4 may be attached to the roof of the pond 600 in the aquaculture farm. Further, as shown in FIG. 12B, the light-shielding shields 1 to 4 may be applied inside the cultivation house 700.

[0056] That is, the severe heat in recent summers has had a profound impact not only in urban areas but also in rural areas. And the impact extends to various fields that are greatly affected by the natural environment, such as agriculture / aquaculture / livestock industry. Therefore, by applying the light-shielding shields 1 to 4 according to the present disclosure to various fields, it is expected to suppress such a profound impact.

[0057] <6. Other Modification Examples> The configurations of the light-shielding shields 1 to 4 according to the first to fourth embodiments have been described above. However, the application of the technical idea of the present disclosure is not limited to the above embodiments. For example, for any of the light-shielding shields 1 to 4, the frame member may be omitted.

[0058] Further, in the light-shielding shield 2 according to the second embodiment, although the reflecting members 20 in the first mesh 10A and the second mesh 10B are both shown to extend along the long side direction X, this is not the only case. That is, in the light-shielding shield 2 according to the second embodiment, one of the reflecting members 20 of the first mesh 10A and the second mesh 10B may be changed to extend in the short side direction Y.
