[Technical Field]

[0001] The present invention relates to a panel and a panel installation structure that exhibits a perspective effect. [Background technology]

[0002] Conventionally, a louver unit having a plurality of louver blades arranged in the vertical direction is known (see Patent Document 1). In this louver unit, the louver blades are attached to a rotating shaft, and the rotation angle of each louver blade can be changed by rotating this rotating shaft, allowing for ventilation and lighting as well as a perspective effect.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-144445 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the louver unit described in Patent Document 1, the louver blades are arranged separately from each other so that the rotation angle of each louver blade can be changed by rotating the rotation shaft. This makes it difficult to increase the strength of the louver blades, and it is difficult to improve the durability of the louver unit against, for example, flying objects. On the other hand, a so-called surface grating can be cited as a highly durable material, but it is difficult for the surface grating to achieve the aforementioned perspective effect.

[0005] An object of the present invention is to provide a panel and a panel installation structure that can achieve a perspective effect and improve durability. [Means for solving the problem]

[0006] The panel of the present invention has at least a first panel layer and a second panel layer stacked in an out-of-plane direction, the first panel layer having at least a first wall portion extending in an in-plane direction to form a through-hole between adjacent portions, the second panel layer having at least a second wall portion extending in the in-plane direction to form a through-hole between adjacent portions, the first wall portion and the second wall portion being arranged overlapping each other in the out-of-plane direction, and the adjacent portions of the first wall portion and the adjacent portions of the second wall portion intersecting each other. The panel installation structure of the present invention is characterized in that a fixture is installed in an opening in a building frame, and the above-mentioned panel of the present invention is installed at a position on one side of the fixture, either indoors or outdoors. [Effects of the Invention]

[0009] [First embodiment] A first embodiment of the present invention will be described below with reference to the drawings. 1 and 2, a panel 10 according to the first embodiment is disposed via brackets 5 on the outdoor side of an operable window 4, which serves as a fixture installed in an opening 3 of a building skeleton 2, and the panel installation structure 1 according to this embodiment is formed by installing the panel 10 in this manner. The panel 10 has a panel layer 20A (first panel layer) and a panel layer 20B (second panel layer) that are stacked in the out-of-plane direction. The operable window 4 is a so-called draped window that can be opened vertically or horizontally. In the following description, the left-right direction of the panel 10 is the X-axis direction, the up-down direction of the panel 10 is the Y-axis direction, and the projection direction of the panel 10 is the Z-axis direction (depth direction). The X, Y, and Z-axis directions are perpendicular to one another. The X and Y-axis directions of the panel 10 are included in the in-plane direction, and the Z-axis direction is included in the out-of-plane direction. Furthermore, the outside and inside sides of the opening / closing window 4 are opposed to each other in the out-of-plane direction.

[0010] As shown in FIGS. 2 to 4, the panel layers 20A and 20B are formed as separate members and are joined together in the Z-axis direction with an adhesive or the like. The panel layer 20A has a rectangular shape overall, and as shown in Fig. 4A, has a first wall portion 24 on the entire surface that extends in the in-plane direction and forms a through-hole 23 between adjacent portions 22. The distance between adjacent portions 22 is constant. The through-hole 23 is formed in a slit shape, but is not limited to this, and may be formed in a hole shape, for example. The first wall portion 24 has first constituent portions 25, 26 in which adjacent portions 22 extend along the X-axis direction (first direction) in the in-plane direction, and second constituent portions 27, 28 that adjoin the first constituent portions 25, 26 and have adjacent portions 22 extending along the Y-axis direction (second direction), and is configured by arranging a plurality of rectangular units 21, each formed by the first constituent portions 25, 26 and the second constituent portions 27, 28, in the vertical and horizontal directions. Note that the unit 21A that forms the right side surface of the panel layer 20A shown in Figure 4(A) is configured as a half unit formed by the first constituent portion 25 and the second constituent portion 28, and in this way the constituent portions of the unit 21 can be changed as appropriate depending on the shape and dimensions of the panel layer 20A. As shown in Fig. 4A, each of the first constituent portions 25, 26 and the second constituent portions 27, 28 is formed in a substantially rectangular shape when viewed from the front. The first constituent portion 25 and the second constituent portion 27 are adjacent to each other in the X-axis direction, and the second constituent portion 28 and the first constituent portion 26 are adjacent to each other in the X-axis direction. The first constituent portion 25 and the second constituent portion 28 are adjacent to each other in the Y-axis direction, and the second constituent portion 27 and the first constituent portion 26 are adjacent to each other in the Y-axis direction. Furthermore, the first constituent portions 25, 26 are disposed diagonally opposite each other, and the second constituent portions 27, 28 are disposed diagonally opposite each other. The first constituent parts 25, 26 and the second constituent parts 27, 28 are each formed continuously in a long length from a continuous resin material, and are configured to be easily formed, for example, by a 3D printer. The panel layer 20A can be formed using a 3D printer, but is not limited to this. For example, it may be formed by injection molding using an injection molding device or by press molding using a press molding device. The panel layer 20A may also be appropriately colored.

[0011] The panel layer 20B has a rectangular shape overall and is disposed rearward relative to the panel layer 20A in the Z-axis direction. As shown in FIG. 4B, the panel layer 20B has, on the entire surface thereof, second wall portions 34 that extend in the in-plane direction and form through-holes 33 between adjacent portions 32. The distance between the adjacent portions 32 is constant. The through-holes 33 are formed in a slit shape, but are not limited to this, and may be formed in a hole shape, for example. The second wall portion 34 has second component portions 37, 38, in which adjacent portions 32 extend along the Y-axis direction (second direction) in the in-plane direction, and first component portions 35, 36, which are adjacent to the second component portions 37, 38 and have adjacent portions 32 extending along the X-axis direction (first direction), and is configured by arranging a plurality of rectangular units 31, each formed by the first component portions 35, 36 and the second component portions 37, 38, in the vertical and horizontal directions. Note that the unit 31A forming the right edge of the panel layer 20B shown in Figure 4(B) is configured as a half unit formed by the second component portion 38 and the first component portion 36, and in this way the component portions of the unit 31 can be changed as appropriate depending on the shape and dimensions of the panel layer 20B. As shown in Fig. 4(B), each of the first component portions 35, 36 and the second component portions 37, 38 is formed in a substantially rectangular shape when viewed from the front. The second component portion 38 and the first component portion 35 are adjacent to each other in the X-axis direction, and the first component portion 36 and the second component portion 37 are adjacent to each other in the X-axis direction. The second component portion 38 and the first component portion 36 are adjacent to each other in the Y-axis direction, and the first component portion 35 and the second component portion 37 are adjacent to each other in the Y-axis direction. Furthermore, the second component portions 37, 38 are disposed diagonally opposite each other, and the first component portions 35, 36 are disposed diagonally opposite each other. The first constituent parts 35, 36 and the second constituent parts 37, 38 are each formed of a continuous, long resin material, and are configured to be easily formed using, for example, a 3D printer. The panel layer 20B can be formed using a 3D printer, but this is not limiting. For example, it may be formed by injection molding using an injection molding device or by press molding using a press molding device. The panel layer 20A may also be colored as appropriate.

[0012] The above-mentioned panel layers 20A and 20B are formed from the same material and have the same shape and dimensions, and panel layer 20B is rotated 90 degrees to the right about an axis along the Z-axis direction relative to panel layer 20A. These panel layers 20A and 20B are stacked in the Z-axis direction and joined together with an adhesive or the like to form a two-layer panel 10. Panel layer 20A is disposed on the front side, and panel layer 20B is disposed on the rear side. The first wall portion 24 and the second wall portion 34 are arranged to overlap each other in the Z-axis direction (out-of-plane direction). The first component portion 25 and the second component portion 38 overlap in the Z-axis direction, the first component portion 26 and the second component portion 37 overlap in the Z-axis direction, the second component portion 27 and the first component portion 35 overlap in the Z-axis direction, and the second component portion 28 and the first component portion 36 overlap in the Z-axis direction.

[0013] In this way, the second component parts 37, 38 are arranged to overlap the first component parts 25, 26 in the Z-axis direction, and the first component parts 35, 36 are arranged to overlap the second component parts 27, 28 in the Z-axis direction, so that adjacent parts 22, 32 of the first wall part 24 and the second wall part 34 are perpendicular to each other. As a result, the panel 10 has a lattice-like (grid-like) appearance when viewed from the front or rear, as shown in Fig. 3. Note that the through-holes 23, 33 formed in the panel 10 provide ventilation and lighting. 2, when the panel 10 is viewed obliquely, the appearance exhibits a perspective effect in which the through-holes 23, 33 are blocked depending on the thickness dimension in the Z-axis direction of the panel layers 20A, 20B (approximately 15 mm in the first embodiment, but not limited to this dimension), and the appearance is changed compared to the appearance when viewed from the front or rear. Note that the area in which the through-holes 23, 33 are blocked changes depending on the angle at which the panel 10 is viewed, and therefore the appearance of the panel 10 changes depending on the angle at which the panel 10 is viewed. In addition, for example, if a flying object strikes a portion of panel layer 20A, panel layer 20A will elastically deform to some extent to disperse the impact, and the force of the impact can be dispersed to other portions of panel layer 20A via panel layer 20B. Even if a portion of panel layer 20A is broken by the impact of a flying object or the like, panel layer 20B will elastically deform and disperse the force of the impact. In this way, panel 10 can disperse external forces applied by flying objects or the like, and can disperse the forces in stages, thereby improving the durability of panel 10. When a flying object or the like strikes the panel layer 20B, the panel layer 20A exerts the above-mentioned function.

[0014] [Second embodiment] 5 and 7, the panel 10B according to the second embodiment is similar to the panel 10 of the first embodiment in that it includes two layers, but differs in that it includes panel layers 40A and 40B instead of panel layers 20A and 20B. The panel layers 40A and 40B are stacked in the out-of-plane direction and bonded to each other with an adhesive or the like. As shown in FIG. 7A, the panel layer 40A (first panel layer) is rectangular overall and has a first wall portion 44 on its entire surface that extends in an in-plane direction and forms through-holes 43 between adjacent portions 42. The through-holes 43 are formed in the shape of a slit or hole. In the first wall portion 44, adjacent portions 42 are arranged in a random manner in the in-plane direction, with components in which the adjacent portions 42 extend along the X-axis direction and components in which the adjacent portions 42 extend along the Y-axis direction. The first wall portion 44 is formed from a continuous, long resin material. As shown in FIG. 7B, the panel layer 40B (second panel layer) is rectangular overall and has second wall portions 54 on the entire surface that extend in the in-plane direction and form through-holes 53 between adjacent portions 52. The through-holes 53 are formed in the shape of slits or holes. In the second wall portion 54, adjacent portions 52 are arranged in the in-plane direction in a random manner, with components in which the adjacent portions 52 extend along the X-axis direction and components in which the adjacent portions 52 extend along the Y-axis direction. The second wall portion 54 is formed from a continuous, long resin material. In the above-described panel 10B, the panel layer 40A is disposed on the front side, and the panel layer 40B is disposed on the rear side, with the first wall portion 44 and the second wall portion 54 overlapping in the Z-axis direction. Furthermore, adjacent portions 42 of the first wall portion 44 and adjacent portions 52 of the second wall portion 54 are disposed so as to intersect at least a portion of the overlapping portion in the Z-axis direction, thereby providing the panel 10B with a unique appearance due to the combination of the panel layers 40A and 40B when viewed from the front or rear, as shown in Fig. 6. Furthermore, the through-holes 43 and 53 formed in the panel 10B provide ventilation and lighting. 5, when viewed obliquely, panel 10B has an appearance that exhibits a perspective effect in which through-holes 43, 53 are blocked depending on the thickness dimension in the Z-axis direction of panel layers 40A, 40B, and presents an appearance that changes compared to the appearance when viewed from the front or rear. Note that the areas where through-holes 43, 53 are blocked vary depending on the angle from which panel 10B is viewed, and therefore the appearance of panel 10B varies depending on the angle from which panel 10B is viewed. In addition, for example, if a flying object strikes a portion of panel layer 40A, panel layer 40A will elastically deform to some extent to disperse the impact, and the force of the impact can be dispersed to other portions of panel layer 40A via panel layer 40B. Even if a portion of panel layer 40A is broken by the impact of a flying object or the like, panel layer 40B will elastically deform to disperse the force of the impact. In this way, panel 10B can disperse external forces applied by flying objects or the like, and can disperse the forces in stages, thereby improving the durability of panel 10B. When a flying object or the like hits the panel layer 40B, the panel layer 40A performs the above-mentioned function.

[0015] [Third embodiment] 8, the panel 10C according to the third embodiment has a four-layer structure including the panel layers 40A and 40B described above, as well as a panel layer 60A (third panel layer) and a panel layer 60B (fourth panel layer). The panel layers 40A and 40B have the same structure as described above, with the panel layer 60A having the same structure as the panel layer 40A, and the panel layer 60B having the same structure as the panel layer 40B. In this panel 10C, the panel layers 40A, 40B, 60A, and 60B are stacked in this order from the front side in the out-of-plane direction and bonded to each other with an adhesive or the like. As described above, panel 10C has four panel layers 40A, 40B, 60A, and 60B, and therefore provides ventilation, lighting, and a perspective effect, while also presenting an appearance that changes in a variety of ways depending on the angle from which panel 10C is viewed, thereby improving design. Furthermore, since panel 10C has four panel layers 40A, 40B, 60A, and 60B, it can disperse impacts from flying objects and the like in more stages and breakage can also be divided into multiple stages compared to, for example, panels 10 and 10B, which have a two-layer structure, thereby achieving greater durability. Although the panel 10C is configured to include the panel layers 40A, 40B, 60A, and 60B, the panel 10C is not limited to this and may be configured to include, for example, three or four or more panel layers each having a different shape.

[0016] [Fourth embodiment] In Figure 9, the panel 10D of the fourth embodiment is configured to include a panel layer 80A (first panel layer) configured with a plurality of units 81 formed in a hexagonal shape when viewed from the front or rear, and a panel layer 80B (second panel layer) configured with a plurality of units 81 formed in a hexagonal shape when viewed from the front or rear. The panel layers 80A, 80B have on their front surfaces a first wall portion 84 and a second wall portion 94 that overlap in the Z-axis direction, and the first wall portion 84 includes a plurality of units 81 that extend in the Y-axis direction and have through-holes 83 formed between adjacent portions 82, and other units 81 that extend along the in-plane direction and in a direction intersecting the X- and Y-axis directions and have through-holes 83 formed between adjacent portions 82. The second wall portion 94 is configured with a plurality of units 81 like the first wall portion 84, but the arrangement and extension direction of adjacent portions across the through-holes differ from those of the first wall portion 84, and the adjacent portions 82 in both the first wall portion 84 and the second wall portion 94 intersect with each other. The aforementioned panel 10D can provide ventilation and lighting by forming through-holes 83 and the like, and can also produce a perspective effect when viewed from an angle, and the appearance of panel 10D can be changed depending on the angle from which panel 10D is viewed. In addition, since the panel 10D is made up of two layers, panel layers 80A and 80B, whose adjacent portions intersect with each other, the durability of the panel can be improved in the same manner as described above. The panel 10D is not limited to the units 81 formed in a hexagonal shape, and may be configured by arranging a plurality of units 81 formed in other polygonal shapes.

[0017] [Destructive testing] A destructive test was conducted on the panel 10B according to the second embodiment. For the destructive test, the panel layer 40A was a single hard layer, and the panel layer 40B was two hard layers. The panel 10B was manufactured using a 3D printer and fixed within the frame of a fixed window. A portion of the panel layer 40A was pressurized in the Z-axis direction from the front side with a hydraulic cylinder, and the load was measured with a load cell at the tip of the hydraulic cylinder. The displacement of the panel 10B was measured from the rear side of the panel 10B using a displacement meter. The results of the destructive test are shown in the graph shown in Figure 10(A). In Figure 10(B), panel layer 40A is labeled as layer 1, and panel layer 40B is labeled as layer 2. In this graph, the vertical axis represents the "load" measured by the load cell, and the load increases as the distance from the "0" position increases upward. The horizontal axis represents the "displacement" measured by the displacement meter, and the displacement increases as the distance from the "0" position increases to the right. This graph shows that after panel layer 40A is pressurized by the hydraulic cylinder and elastically deforms to break, the load decreases, and panel layer 40B elastically deforms, causing other portions of panel layer 40A other than the broken portion to withstand a certain amount of load before breaking. Then, the load decreases again, and panel layer 40B elastically deforms to withstand a certain amount of load before breaking. This shows that the load force applied to panel 10B pressurized by the hydraulic cylinder is distributed in stages according to the amount of displacement. The results of the destructive test show that when a portion of panel 10B is subjected to a load from the front side, as shown in Figure 10 (B), even if the "first layer (panel layer 40A)" elastically deforms and breaks, the "second layer (panel layer 40B)" elastically deforms, thereby suppressing the destruction of panel 10B and improving the durability of panel 10B. Furthermore, when the panel layer 40A is not broken, the durability of the panel 10B is improved by the elastic deformation of the panel layer 40A and the panel layer 40B.

[0018] [Action and effect] The panels 10, 10B, 10C, and 10D of this embodiment have first wall portions 24, 44, and 84 and second wall portions 34, 54, and 94 that are arranged so as to overlap each other in the out-of-plane direction, so that the respective through-holes 23, 33, 43, 53, and 83 also overlap each other in the out-of-plane direction, allowing for ventilation and lighting while also achieving the aforementioned oblique effect. Furthermore, since the longitudinal directions of adjacent portions 22, 32, 42, 52, 82 of the first wall portions 24, 44, 84 and the second wall portions 34, 54, 94 intersect with each other, the external design of the panels 10, 10B, 10C, 10D can be changed depending on the direction from which they are viewed.In addition, even if, for example, a portion of the panel layer 20A, 40A, 60A, 80A is pressed, the force can be distributed to the aforementioned panel layers 20B, 40B, 60B, 80B, etc., thereby improving the durability of the panels 10, 10B, 10C, 10D against flying objects, etc. The unit 21 in the first wall portion 24 of the panel layer 20A has first constituent portions 25, 26 and second constituent portions 27, 28, and the unit 31 in the second wall portion 34 of the panel layer 20B has first constituent portions 35, 36 and second constituent portions 37, 38, so that the rigidity of the first wall portion 24 and the second wall portion 34 can be increased, and the durability of the panel 10 can be improved. In panels 10, 10B, 10C, and 10D, panel layers 20A, 40A, 60A, and 80A are formed separately from panel layers 20B, 40B, 60B, and 80B, which improves ease of manufacturing, and can make manufacturing significantly easier, especially when constructing a panel by stacking three or more panel layers.

[0019] [Variations] In the above embodiment, first wall portions 24, 44, 84 are formed on the entire surface of panel layers 20A, 40A, 60A, 80A, and second wall portions 34, 54, 94 are formed on the entire surface of panel layers 20B, 40B, 60B, 80B, but this is not limited to this. For example, first wall portions 24, 44, 84 and second wall portions 34, 54, 94 may be formed on a portion of panel layer 20A, 40A, 60A, 80A or panel layer 20B, 40B, 60B, 80B, and a planar portion (not shown) that does not penetrate in the Z-axis direction may be formed on another portion of panel layer 20A, 40A, 60A, 80A or panel layer 20B, 40B, 60B, 80B. In the above embodiment, at least one of the panel layers 20A, 20B, 40A, 40B, 60A, 60B, 80A, and 80B may be entirely made of the same material, or may be made by laminating layers with different physical properties. For example, at least one of the panel layers 20A, 20B, 40A, 40B, 60A, 60B, 80A, and 80B may be made by laminating hard layers and soft layers, in which case, the hard layers and soft layers may be alternately laminated. By alternately laminating hard layers and soft layers in this manner, the rigidity of the panel layers 20A, 20B, 40A, 40B, 60A, 60B, 80A, and 80B themselves is primarily maintained by the hard layers, while the soft layers can absorb impacts, such as those caused by collisions with flying objects, thereby further improving the durability of the panels 10, 10B, 10C, and 10D. In the above embodiment, the first wall portions 24, 44, 84 and the second wall portions 34, 54, 94 are made of a continuous, long resin material, but this is not limited thereto. As long as they are moldable, at least one of the first wall portions 24, 44, 84 and the second wall portions 34, 54, 94 may be made of a segmented material. In the above embodiment, the adjacent portions 22, 42, 82 of the first wall portions 24, 44, 84 and the adjacent portions 32, 52 of the second wall portions 34, 54, 94 intersect with each other, but this is not limiting and there may be portions where no intersection occurs. In the above embodiment, the panel layers 20A, 40A, 60A, 80A and the panel layers 20B, 40B, 60B, 80B are constructed as separate members and joined together, but this is not limited to this. For example, the panel layers 20A, 40A, 60A, 80A and the panel layers 20B, 40B, 60B, 80B may be formed continuously and integrally. In the above embodiment, the panel layers 20A, 40A, 60A, and 80A and the panel layers 20B, 40B, 60B, and 80B have the same thickness. However, this is not limiting and the panel layers may have different thicknesses. In this case, when the panels 10, 10B, 10C, and 10D are viewed obliquely, the appearances of the panels 10, 10B, 10C, and 10D can be changed depending on whether they are viewed from the front or rear. Furthermore, the durability characteristics of the panels 10, 10B, 10C, and 10D can be changed as needed. In the above embodiment, the panel 10 is disposed on the outdoor side in the Z-axis direction relative to the operable window 4, but this is not a limitation and the panel may be disposed on the indoor side in the Z-axis direction. The same applies to the panels 10B, 10C, and 10D. Furthermore, the panels 10, 10B, 10C, and 10D are not limited to being disposed and used as described above, and may be installed, for example, as a face material within the window frame of a fixed window, or may be attached to an aluminum extrusion and installed. In the above embodiment, the opening / closing window 4 is used as the fixture, but the fixture is not limited to the opening / closing window 4, and various other casement windows may also be used as the fixture.

[0020] [Summary of the present invention] (1) The panel of the present invention has at least a first panel layer and a second panel layer stacked in an out-of-plane direction, the first panel layer having at least a first wall portion extending in an in-plane direction to form a through-hole between adjacent portions, the second panel layer having at least a second wall portion extending in the in-plane direction to form a through-hole between adjacent portions, the first wall portion and the second wall portion being arranged overlapping each other in the out-of-plane direction, and the adjacent portions of the first wall portion and the adjacent portions of the second wall portion intersecting each other. According to the panel of the present invention, since it has a first wall portion and a second wall portion that are arranged to overlap each other in the out-of-plane direction, the respective through-holes also overlap in the out-of-plane direction, allowing for ventilation and lighting while also achieving the aforementioned perspective effect. Furthermore, adjacent parts of the first wall portion and adjacent parts of the second wall portion intersect with each other, so the external design can be configured to change depending on the direction from which the panel is viewed, thereby improving the design.In addition, even if, for example, part of the first panel layer is pressed, the force can be distributed to the second panel layer mentioned above, etc., thereby improving the durability of the panel against flying objects, etc. (2) In the panel of the present invention, at least one of the first wall portion and the second wall portion may have, in the in-plane direction, a first component portion in which the adjacent portions extend along a first direction, and a second component portion adjacent to the first component portion and in which the adjacent portions extend along a second direction that intersects with the first direction. With this configuration, at least one of the first wall portion and the second wall portion has the above-mentioned first component portion and second component portion, so that the rigidity of that one wall portion can be increased, thereby improving the durability of the panel. (3) In the panel of the present invention, at least one of the first panel layer and the second panel layer laminated in the out-of-plane direction may be formed by laminating a hard layer and a soft layer. With this configuration, the rigidity of the panel layer itself is maintained mainly by the hard layer, while the soft layer can absorb the impact of a collision with a flying object, for example, and therefore the durability of the panel can be improved. For example, in the case where a plurality of hard layers and soft layers are alternately laminated, even if a hard layer breaks, the soft layer absorbs the impact, so that breakage of the other hard layers can be suppressed. (4) In the panel of the present invention, the first panel layer and the second panel layer may be formed as separate members and joined to each other. This configuration can improve ease of manufacturing compared to when the first panel layer and the second panel layer are formed continuously and integrally, and can make manufacturing significantly easier, especially when the panel is constructed by stacking three or more panel layers. (5) The panel installation structure of the present invention is characterized in that a fixture is installed in an opening in a building structure, and the aforementioned panel of the present invention is installed at one side of the fixture, either indoors or outdoors. According to the panel installation structure of the present invention, it is possible to configure a panel installation structure that can exhibit the effects of the panel of the present invention described above.
