[0003] [Patent Document 1] Patent No. 7457089 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, display devices such as those of the above-mentioned conventional technology are sometimes installed on building walls. In this case, decorative panels are expected to be installed on the building wall above and below the display device to hide the presence of the display device. However, in such a wall structure, the display device is blocked above and below by the decorative panels, which can make it difficult to dissipate heat generated by the display.

[0005] An object of the present invention is to provide a wall structure that can effectively exhaust heat generated from a display. [Means for solving the problem]

[0006] (1) A wall structure according to one aspect of the present invention comprises an architectural wall, a display device installed on the architectural wall, and a false wall arranged above and / or below the display device on the near side of the architectural wall, wherein the display device has a display attached to the architectural wall and a display cover attached to the architectural wall and covering the display, the display cover is arranged facing the display and has a front panel that transmits light emitted from the display, and a display decorative sheet that transmits light and is provided on the surface of the front panel, and a space is provided between the architectural wall and the false wall.

[0007] In this type of wall structure, a space is provided between the architectural wall and the false wall. This allows the heat generated by the display to flow from below to above through the space and escape to the ceiling as exhaust heat due to its temperature characteristics. This allows the heat generated by the display to be efficiently exhausted.

[0008] (2) In the above (1), an auxiliary decorative sheet having the same structure as the display decorative sheet may be provided on the surface of the false wall. In this configuration, the display decorative sheet of the display cover and the auxiliary decorative sheet of the false wall have the same structure, resulting in a wall structure that has a unified appearance when viewed from the front side, and can improve the appearance of the wall structure.

[0009] (3) In the above (1) or (2), the false wall may be fixed to the architectural wall via a plurality of pillar members, and the space may be defined by the architectural wall, the false wall, and the plurality of pillar members. In this configuration, the false wall can be easily fixed to the architectural wall, while a space can be secured between the architectural wall and the false wall.

[0010] (4) In any of the above (1) to (3), a dust removal member for removing dust may be disposed on the edge of the front surface of the display on the side of the front panel. In such a configuration, when dust present in the space flows from below to above together with the exhaust heat, the dust is attracted to the dust removal member, thereby preventing dust from adhering to the front surface of the display. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a wall structure that can effectively exhaust heat generated from a display. [Brief explanation of the drawings]

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0014] Fig. 1 is a front view showing a wall structure according to one embodiment of the present invention. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. In Figs. 1 and 2, a wall structure 100 according to this embodiment includes an architectural wall 1 and a display device 4 installed on the architectural wall 1. The architectural wall 1 has a structure in which, for example, a plasterboard 3 is joined to a wall main body 1A via structural plywood 2.

[0015] The display device 4 includes a display 5 attached to the architectural wall 1 and a display cover 6 attached to the architectural wall 1 and covering the display 5. Here, the X direction of the display device 4 is the width direction (left-right direction) of the display device 4. The Y direction of the display device 4 is the height direction (up-down direction) of the display device 4. The Z direction of the display device 4 is the depth direction (front-back direction) of the display device 4.

[0016] The display 5 is, for example, a panel display using surface-mounted LEDs. When viewed from the front, the display 5 has a horizontally long rectangular shape. In other words, the width dimension (X direction) of the display 5 is greater than the height dimension (Y direction) of the display 5. The display 5 is detachably attached to the wall surface 1a of the architectural wall 1 via a mounting bracket 7. When the display 5 is attached to the architectural wall 1, a space S is formed between the display 5 and the architectural wall 1.

[0017] A dust removal member 8 for removing dust is attached to the edge of the front surface 5a of the display 5 (see FIGS. 8 and 10). The front surface 5a of the display 5 is the surface of the display 5 facing the front panel 12 (described later). The dust removal member 8 is attached to the edge of the front surface 5a of the display 5 around the entire periphery of the display 5. The dust removal member 8 may be, for example, a sponge.

[0018] The display cover 6 includes a box-shaped cover body 9. The cover body 9 includes a housing 10 and a decorative sheet 11 provided on the surface of the housing 10, as shown in FIG.

[0019] The housing 10 is disposed to house the display 5 and transmits light emitted from the display 5. The housing 10 is formed of a light-transmitting resin such as acrylic. In this example, the housing 10 is formed of a gray smoke acrylic plate.

[0020] The housing 10 has a front panel 12 arranged to face the display 5, and side panels 13 erected from the periphery of the front panel 12 toward the building wall 1 so as to surround the display 5.

[0021] The front panel 12 has a rectangular shape when viewed from the depth direction (Z direction). The side panels 13 are made up of an upper panel 14 connected to the upper edge of the front panel 12, a lower panel 15 connected to the lower edge of the front panel 12, and side panels 16 and 17 connected to the side edges on both sides of the front panel 12, respectively.

[0022] The decorative sheet 11 is a display decorative sheet and is attached to the surface of the housing 10. The surface of the housing 10 is the outer surface of the housing 10. The decorative sheet 11 is a printed sheet for expressing a pattern. The decorative sheet 11 is made up of decorative sheets 11A to 11E.

[0023] Decorative sheet 11A is attached to the entire surface of front panel 12. Decorative sheet 11B is attached, for example, to the front surface of top panel 14 (see FIG. 7). Decorative sheet 11C is attached, for example, to the front surface of bottom panel 15. Decorative sheets 11D and 11E are attached, for example, to the entire surfaces of side panels 16 and 17, respectively.

[0024] 4, the decorative sheet 11 has a light-transmitting base material 21, a picture print layer 22, and a light-transmitting smoke print layer 23. The light-transmitting base material 21 is disposed on the front side (opposite the display 5) in the depth direction (Z direction) of the decorative sheet 11. In other words, the light-transmitting smoke print layer 23 is disposed closer to the display 5 than the light-transmitting base material 21.

[0025] The light-transmitting substrate 21 is a substrate that is transparent to visible light. The light-transmitting substrate 21 is formed of, for example, a transparent resin. Examples of transparent resins include PET, PMMA, polyethylene, polypropylene, and nylon. If necessary, a surface protection layer may be provided on the surface side of the light-transmitting substrate 21 (the side opposite to the picture print layer 22).

[0026] The picture-printed layer 22 is a layer that expresses the picture of the printed matter. The picture-printed layer 22 has a first color pattern layer 24 provided on one surface of the light-transmitting substrate 21 and a second color pattern layer 25 provided on the first color pattern layer 24.

[0027] The first color pattern layer 24 and the second color pattern layer 25 are formed by, for example, screen printing, inkjet printing, gravure printing, offset printing, etc. The first color pattern layer 24 and the second color pattern layer 25 are composed of a plurality of dots (not shown). Here, a dot is a point that is an element that constitutes a printed image.

[0028] The transparent smoke printed layer 23 is a layer for attenuating light transmitted through the decorative sheet 11. The transparent smoke printed layer 23 is provided on the outermost surface of the picture printed layer 22, opposite the light-transmitting substrate 21. The transparent smoke printed layer 23 is provided on the second color pattern layer 25. The transparent smoke printed layer 23 is formed by, for example, screen printing, inkjet printing, gravure printing, offset printing, etc., using ink in which a small amount of carbon black is dispersed in a resin binder such as a vinyl-based, acrylic-based, urethane-based, or polyester-based binder.

[0029] In such a decorative sheet 11, when the display 5 is not lit, the pattern of the pattern-printed layer 22 is visible. When the display 5 is lit, transmitted light from the display 5 (pattern display, video display, etc.) is visible.

[0030] When producing the cover body 9 as described above, first, a flat acrylic plate 19 is prepared, as shown in Fig. 5(a). Then, as shown in Fig. 5(b), the acrylic plate 19 is processed into a box shape to form the housing 10. Thereafter, as shown in Fig. 5(c), decorative sheets 11A to 11E are attached to the surfaces of the front panel 12, top panel 14, bottom panel 15, and side panels 16 and 17 of the housing 10, respectively. In this way, the cover body 9 is obtained.

[0031] Fig. 6 is a perspective view of the display cover 6 as seen from the front side. Fig. 7 is a plan view of the display cover 6 shown in Fig. 6. In Fig. 6 and Fig. 7, the dimensions in the depth direction (Z direction) of the upper panel 14 and the lower panel 15 of the side panel 13 are smaller than the dimensions in the depth direction of the side panels 16 and 17 of the side panel 13.

[0032] A support member 30 is fixed to the rear end of the side plate 13. The rear end of the side plate 13 is the end of the side plate 13 opposite the front plate 12. The support member 30 is a member for supporting the housing 10 on the building wall 1.

[0033] The support member 30 is composed of supports 31A and 31B (see Figure 2) fixed to the rear ends of the upper and lower plates 14 and 15, respectively, and supports 32A and 32B fixed to the rear ends of the side plates 16 and 17, respectively.

[0034] The supports 31A and 31B support the housing 10 on the building wall 1 and also have the function of reinforcing the upper panel 14 and the lower panel 15. The supports 31A and 31B extend in the width direction (X direction) of the display cover 6 up to the vicinity of the side panels 16 and 17. In other words, a gap is provided between the support 31A and the side panels 16 and 17. A gap is provided between the support 31B and the side panels 16 and 17. Note that both ends of the supports 31A and 31B may be in contact with the side panels 16 and 17, respectively. The supports 31A and 31B are formed of, for example, aluminum.

[0035] As shown in Fig. 8, the support body 31A has a substantially rectangular cylindrical main body 33 arranged on the inner surface side of the top plate 14, and a protective part 34 with an L-shaped cross section that is integrated with the main body 33 and covers the rear end surface 14a of the top plate 14. The inner surface of the top plate 14 is the inner surface of the top plate 14 (the surface facing the display 5). The rear end surface 14a of the top plate 14 is the end surface of the top plate 14 opposite to the front plate 12. The support body 31A is fixed to the top plate 14 with multiple (three in this case) screws 35 (see Figs. 6 and 7).

[0036] To the support body 31A, multiple sets (three sets in this case) of mounting brackets 36 and mounting plates 37 are connected for attaching the housing 10 to the building wall 1. These mounting brackets 36 and mounting plates 37 are arranged at predetermined intervals in the width direction (X direction). The mounting brackets 36 and mounting plates 37 are made of, for example, iron.

[0037] The mounting bracket 36 is connected to the support body 31A so as to be positioned behind the support body 31A. The mounting bracket 36 is attached to the building wall 1 via a mounting plate 37. The mounting bracket 36 has a main body 36a with an inverted U-shaped cross section and two protruding portions 36b that protrude from both ends of the main body 36a to opposite sides in the depth direction (Z direction). The main body 36a is connected to the main body 33 of the support body 31A by screws 38. The mounting bracket 36 has dimensions that ensure the necessary strength and do not hinder the dissipation of heat from the display 5, which will be described later.

[0038] The mounting plate 37 has a bent shape that extends from the top plate 14 along the main body 33 of the support body 31A to the rear end of the mounting bracket 36. One end of the mounting plate 37 is in contact with the inner surface of the top plate 14. One end of the mounting plate 37 may be joined to the inner surface of the top plate 14. The other end of the mounting plate 37 protrudes to a position higher than the mounting bracket 36.

[0039] The mounting plate 37 is connected to the main body 33 of the support body 31A by screws 39. The portion of the mounting plate 37 that protrudes beyond the mounting bracket 36 (the other end of the mounting plate 37) serves as a fastening portion 40 that is fastened to the architectural wall 1. In other words, the mounting plate 37 has the fastening portion 40.

[0040] Although not specifically shown, the support body 31B has a main body portion 33 and a protective portion 34, similar to the support body 31A. The main body portion 33 is disposed on the inner surface side of the lower plate 15. The protective portion 34 covers the rear end surface (not shown) of the lower plate 15.

[0041] Although not specifically shown, mounting brackets 36 and mounting plates 37 are connected to support body 31B, similar to support body 31A. Multiple sets (two sets in this case) of mounting brackets 36 and mounting plates 37 are connected to support body 31B (see FIG. 1). These mounting brackets 36 and mounting plates 37 are arranged in a staggered manner with respect to the multiple sets of mounting brackets 36 and mounting plates 37 connected to support body 31A.

[0042] The supports 32A and 32B support the housing 10 on the building wall 1 and also have the function of reinforcing the side panels 16 and 17. The supports 32A and 32B extend in the height direction (Y direction) of the display cover 6. The supports 32A and 32B are made of the same material as the supports 31A and 31B.

[0043] 9, the support body 32B has a substantially rectangular cylindrical main body 43 arranged on the inner surface side of the side panel 17, and a protective part 44 with an L-shaped cross section that is integrated with the main body 43 and covers the rear end surface 17a of the side panel 17. The inner surface of the side panel 17 is the inner surface of the side panel 17 (the surface facing the display 5). The rear end surface 17a of the side panel 17 is the end surface of the side panel 17 opposite to the front panel 12. The support body 32B is fixed to the side panel 17 with a plurality of screws 45.

[0044] A plurality of mounting plates 46 for mounting the housing 10 to the building wall 1 are attached to the support body 32B. The mounting plates 46 are arranged at predetermined intervals in the height direction (Y direction). The mounting plates 46 are made of, for example, iron.

[0045] The mounting plate 46 has a curved shape that extends from the side plate 17 to the rear end of the support body 32. One end of the mounting plate 46 is in contact with the inner surface of the side plate 17. One end of the mounting plate 46 may be joined to the inner surface of the side plate 17. The other end of the mounting plate 46 is in contact with the rear end of the support body 32. The other end of the mounting plate 46 may be joined to the rear end of the support body 32.

[0046] The mounting plate 46 has a fastening portion 47 that is fastened to the architectural wall 1. The fastening portion 47 protrudes to a position above the support body 32B (see FIG. 6).

[0047] Although not specifically shown, the support body 32A has a main body portion 43 and a protective portion 44, similar to the support body 32B described above. The main body portion 43 is disposed on the inner surface side of the side panel 16. The protective portion 44 covers the rear end surface (not shown) of the side panel 16. Also, similar to the support body 32B described above, an attachment plate 46 is connected to the support body 32A.

[0048] 8 and 10, a black sheet 51, which is a non-transparent material that does not have optical transparency, is disposed around the display 5 on the inner surface of the front panel 12. As the black sheet 51, for example, a black cutting sheet is used.

[0049] The black sheet 51 is attached to the entire inner surface of the front panel 12 between the display 5 and the top panel 14, bottom panel 15, and side panels 16 and 17. The black sheet 51 is also attached to the front portions of the inner surfaces of the top panel 14, bottom panel 15, and side panels 16 and 17. As a result, the display 5 cannot be seen from the front side of the display device 4, and therefore the presence of the display 5 cannot be known.

[0050] Returning to FIGS. 1 and 2, the wall structure 100 further includes false walls 60 and 65 arranged above and below the display device 4 on the front side of the architectural wall 1.

[0051] The false wall 60 is fixed to the architectural wall 1 via a plurality of pillar members 61. A space S1 is formed between the false wall 60 and the architectural wall 1. The space S1 is defined by the architectural wall 1, the false wall 60, and the plurality of pillar members 61. A gap is provided between the display device 4 and the false wall 60. A gap is provided between the false wall 60 and the ceiling 64.

[0052] The false wall 60 has a plasterboard 62 fixed to a pillar member 61 and a decorative sheet 63 attached to the front surface of the plasterboard 62. The decorative sheet 63 is an auxiliary decorative sheet and is provided on the surface of the false wall 60. The structure of the decorative sheet 63 is the same as that of the decorative sheet 11 of the display cover 6.

[0053] The false wall 65 is positioned away from the floor surface 66. The false wall 65 is fixed to the architectural wall 1 via a plurality of pillar members 67. A space S2 is formed between the false wall 65 and the architectural wall 1. The space S2 is defined by the architectural wall 1, the false wall 65, and the plurality of pillar members 67. A gap is provided between the display device 4 and the false wall 65. Like the false wall 60, the false wall 65 has a plasterboard 62 and a decorative sheet 63. The decorative sheet 63 is provided on the surface of the false wall 65.

[0054] In this way, spaces S1 and S2 are provided between the architectural wall 1 and the false walls 60 and 65, respectively. Therefore, the heat generated from the display 5 flows from below to above as exhaust heat due to the temperature characteristics as shown in Fig. 11 (see arrows). The exhaust heat then travels along the architectural wall 1 and escapes to the ceiling 64.

[0055] Floating walls 68 are disposed on both the left and right sides of the display device 4. Although not specifically shown, the floating walls 68 have the same structure as the floating walls 60 and 65. A gap is provided between the display device 4 and the floating walls 68.

[0056] 12, the area between the false walls 60 and 65 in the architectural wall 1 is a display area 70 in which the display device 4 is placed. The above-mentioned mounting bracket 7 for detachably mounting the display 5 is fixed to the center of the display area 70.

[0057] As shown in Fig. 8, a rectangular cylindrical positioning bar 71 for positioning the display cover 6 is fixed to the upper part of the display area 70. The positioning bar 71 extends in the width direction (X direction). The positioning bar 71 is fixed to the building wall 1 by screws 72. The positioning bar 71 is made of aluminum, for example. The positioning bar 71 has an upper surface 71a which is a mounting surface on which the mounting bracket 36 of the display cover 6 is placed.

[0058] In the wall structure 100 described above, when attaching the display device 4 to the architectural wall 1, first the display 5 is attached to the mounting bracket 7. Then, with the mounting bracket 36 of the display cover 6 temporarily placed on the positioning bar 71, the fastening portion 40 of the mounting plate 37 of the display cover 6 is screwed and fastened to the architectural wall 1 with a plurality of screws 74 (see FIG. 8), and the fastening portion 47 of the mounting plate 46 of the display cover 6 is screwed and fastened to the architectural wall 1 with a plurality of screws 75 (see FIG. 9). In this way, the display device 4 is fixed to the architectural wall 1 while being disposed between the upper and lower false walls 60, 65.

[0059] As described above, in this embodiment, spaces S1 and S2 are provided between the architectural wall 1 and the false walls 60 and 65. As a result, heat generated from the display 5 flows from below to above through the space S1 as exhaust heat due to temperature characteristics and escapes to the ceiling 64. Therefore, the heat generated from the display 5 can be efficiently exhausted.

[0060] Furthermore, in this embodiment, the decorative sheet 11 of the display cover 6 and the decorative sheet 63 of the raised walls 60, 65 have the same structure, so that the wall structure 100 has a unified appearance when viewed from the front side, thereby improving the appearance of the wall structure 100.

[0061] In this embodiment, the false walls 60, 65 are fixed to the architectural wall 1 via pillar members 61, 67, respectively. Therefore, the false walls 60, 65 can be easily fixed to the architectural wall 1, while spaces S1, S2 can be secured between the architectural wall 1 and the false walls 60, 65.

[0062] In this embodiment, a dust removal member 8 for removing dust is disposed on the edge of the front surface 5a of the display 5. Therefore, when dust present in the spaces S1 and S2 flows from below to above together with the exhaust heat, the dust is adsorbed by the dust removal member 8, and therefore, adhesion of dust to the front surface 5a of the display 5 is suppressed.

[0063] The present invention is not limited to the above embodiment. For example, in the above embodiment, the supports 31A and 31B fixed to the upper and lower panels 14 and 15 of the side panel 13, respectively, are attached to the architectural wall 1 via the mounting brackets 36, but the present invention is not particularly limited to such an embodiment. The supports 32A and 32B fixed to the side panels 16 and 17 of the side panel 13, respectively, may be attached to the architectural wall 1 via the mounting brackets.

[0064] In addition, in the above embodiment, the mounting bracket 36 is attached to the architectural wall 1 via the mounting plate 37, but this is not particularly limited to such a configuration. For example, the mounting bracket 36 may be provided with a fastening portion that is fastened to the architectural wall 1, so that the mounting bracket 36 can be attached directly to the architectural wall 1.

[0065] In the above embodiment, the decorative sheet 11 is provided on the surfaces of the front plate 12 and the side plates 13 of the housing 10, but this is not a particular limitation. For example, the decorative sheet 11 may be provided only on the surface of the front plate 12.

[0066] Furthermore, in the above embodiment, the structure of the decorative sheet 63 of the raised walls 60, 65 is the same as the structure of the decorative sheet 11 of the display cover 6, but this is not particularly limited to that form, and the structure of the decorative sheet 63 and the structure of the decorative sheet 11 may be different.

[0067] Furthermore, in the above embodiment, the housing 10 is made of a resin such as acrylic, but is not limited to this form, and the housing 10 may be made of transparent glass or the like.

[0068] In the above embodiment, the display device 4 has a horizontally long rectangular shape in which the width (X direction) dimension is greater than the height (Y direction) dimension, but is not limited to such a shape. The display device 4 may have a vertically long rectangular shape in which the height dimension is greater than the width dimension, or may have a square shape in which the width dimension is equal to the height dimension.

[0069] Furthermore, in the above embodiment, a gap is provided between the display device 4 and the false walls 60, 65, 68, but this is not a particular limitation, and the display device 4 and the false walls 60, 65, 68 may be in contact with each other.

[0070] In addition, in the above embodiment, false walls 60, 65 are respectively arranged above and below the display device 4, but this is not particularly limited to such a configuration. For example, if the display device 4 is installed in the upper part of the architectural wall 1, a false wall may be arranged only below the display device 4. If the display device 4 is installed in the lower part of the architectural wall 1, a false wall may be arranged only above the display device 4.

[0071] Furthermore, in the above embodiment, one display device 4 is attached to the wall surface 1a of the architectural wall 1, but this is not particularly limited to this form, and multiple display devices 4 may be attached to the wall surface 1a of the architectural wall 1 in a state lined up in the width direction (X direction).
