[0009] In the embodiments of the present invention, the description will be divided into multiple sections as necessary, but in principle, they are not unrelated to each other, and one is related to the other as a partial or complete modification, detail, etc. For this reason, in all the drawings, components having the same function are given the same reference numerals, and repeated explanations thereof will be omitted.

[0010] Furthermore, the number of components (including the number, numerical value, amount, range, etc.) is not limited to a specific number, and may be more or less than a specific number, unless otherwise specified or clearly limited in principle to a specific number. Furthermore, when referring to the shape of a component, etc., it includes things that are substantially similar or approximate to that shape, etc., unless otherwise specified or clearly considered not to be the case in principle.

[0011] A display device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the display device, and FIG. 2 is a side view of the display device. For ease of explanation, the up-down direction in FIG. 1 is referred to as the height direction of the display device 10, and the left-right direction in FIG. 2 is referred to as the front-rear direction of the display device 10. The display device 10 is mainly installed outdoors, such as in a store parking lot or a construction site, and displays advertisements and information to passersby and drivers. The display device 10 has support posts 11a and 11b, a beam 12 supported by the support posts 11a and 11b, and a base 20 that supports the support posts 11a and 11b. The base 20 has support legs 21a and 21b extending in the front-rear direction of the display device 10, and a beam 22 suspended between the support legs 21a and 21b.

[0012] The stand 20 has casters 18. The display device 10 has the casters 18, which makes it movable.

[0013] The stand 20 has an adjuster 19. The display device 10 can be installed outdoors (such as in a parking lot). In outdoor parking lots, the installation surface may be uneven. For this reason, it is advisable to extend and retract the adjuster 19 to install the display device 10 horizontally. In addition, the display device 10 can be fixed in place while being moved by the casters 18.

[0014] The display device 10 includes a first display unit 15 that displays images, videos, and the like, and a first right frame 13a and a first left frame 13b that support the first display unit 15. The first display unit 15 is, for example, an LED panel with an array of LEDs. The first right frame 13a is attached along one side of the first display unit 15 that extends in the height direction, and the first left frame 13b is attached along the other side of the first display unit 15 that extends in the height direction. The first right frame 13a is connected to a support column 11a by a hinge 17. The connection via the hinge 17 allows the first right frame 13a to rotate about the support column 11a. Therefore, the first display unit 15 connected to the first right frame 13a and the first left frame 13b connected to the first display unit 15 can rotate about the support column 11a.

[0015] The length in the height direction of the first right frame 13a is preferably equal to or longer than the length in the height direction of the first display unit 15. By making the length equal to or longer than the length in the height direction of the display unit 15, it is possible to protect the sides of the first display unit 15. Furthermore, the length in the height direction of the first left frame 13b is preferably equal to the length in the height direction of the first display unit 15 plus the length from the bottom surface of the first display unit 15 to the plane of the pedestal 20. By making the length like this, the first left frame 13b can support the first display unit 15 as it rotates.

[0016] The display device 10 includes a second display unit 16 that displays images, videos, and the like, and a second right frame 14a and a second left frame 14b that support the second display unit 16. The second display unit 16 is, for example, an LED panel with an array of multiple LEDs. The second right frame 14a is attached along one side of the second display unit 16 that extends in the height direction, and the second left frame 14b is attached to the other side of the second display unit 16 that extends in the height direction. The second right frame 14a is connected to a support column 11a via a hinge 17. The hinge 17 allows the second right frame 14a to rotate about the support column 11a. Therefore, the second display unit 16 attached to the second right frame 14a and the second left frame 14b connected to the second display unit 16 can also rotate about the support column 11a.

[0017] The length in the height direction of the second right frame 14a is preferably equal to or longer than the length in the height direction of the second display unit 16. By making the length equal to or longer than the length in the height direction of the second display unit 16, the sides of the display unit 16 can be protected. Furthermore, the length in the height direction of the second left frame 14b is preferably equal to the length in the height direction of the display unit 16 plus the length from the bottom surface of the display unit 16 to the plane of the pedestal 20. By making the length like this, the second left frame 14b can support the second display unit 16 as it rotates.

[0018] Fig. 3 is a plan view of the display device 10. For ease of explanation, Fig. 3 shows a part of the display device 10 with a dashed line. The direction of the beam 12 in Fig. 3 is referred to as the central direction. Figs. 4 and 5 are explanatory diagrams of the lower fixing part 70. The display device 10 has the lower fixing part 70 that fixes the first display unit 15 and the second display unit 16 at the bottom of the display device 10.

[0019] The lower fixing part 70 has a plate 87, holes 71 to 75, and a member 81. The plate 87 is provided on the mount 20, and the holes 71 to 75 are provided in the plate 87. The holes 71 to 75 are used to fix the first display unit 15 to the plate 87, for example, via bolts. The holes 71 to 75 are provided on the locus of a hole 83 of the member 81 that rotates on the plate 87. The member 81 and the hole 83 will be described later.

[0020] Hole 71 is provided closest to beam 12 among holes 71 to 75. Hole 71 is for fixing display unit 15 so that it is parallel to beam 12. Hereinafter, the state in which first display unit 15 (second display unit 16) is parallel to beam 12 will be referred to as the closed state. Hole 72 is provided so that when first display unit 15 is rotated forward from the closed state, the angle α of rotation of first display unit 15 is 5 degrees. Hole 73 is provided so that the angle α of rotation of first display unit 15 is 10 degrees. Hole 74 is provided so that the angle α of rotation of first display unit 15 is 15 degrees. Hole 75 is provided so that the angle α of rotation of first display unit 15 is 20 degrees. In other words, holes 71 to 75 are provided so that the angles α of rotation of first display unit 15 are 0 degrees, 5 degrees, 10 degrees, 15 degrees, and 20 degrees. The angle α and the number of holes 71 to 75 are not limited to the above.

[0021] The lower fixing part 70 includes a member 81. The member 81 is provided at the lower part of the rotating first left frame 13b. The member 81 can move on a plate 87 as the first left frame 13b rotates. The member 81 is provided with a hole 83. The member 81 is fixed to the plate 87 by overlapping the hole 83 with one of the holes 71 to 75 of the plate 87. The hole 83 of the member 81 and each of the holes 71 to 75 of the plate 87 can be fastened with a bolt or the like. The user of the display device 10 can use the lower fixing part 70 to fix the first display unit 15 at a desired angle α (0 degrees, 5 degrees, 10 degrees, 15 degrees, or 20 degrees in this embodiment).

[0022] The lower fixing portion 70 has holes 76 to 80 and a member 82. The holes 76 to 80 are provided in a plate 87. The holes 76 to 80 are used to fix the second display unit 16 to the plate 87, for example, via bolts. The holes 76 to 80 are provided on the trajectory of a hole 84 of a member 83 that rotates on the plate 87. The member 82 and the hole 84 will be described later.

[0023] Hole 76 is provided closest to beam 12 among holes 76-80. Hole 76 is a hole for fixing second display unit 16 in a closed state. Hole 77 is a hole provided so that when second display unit 16 is rotated rearward from the closed state, the angle β of second display unit 16 is 5 degrees. Hole 78 is provided so that angle β is 10 degrees. Hole 79 is provided so that angle β is 15 degrees. Hole 80 is provided so that angle β is 20 degrees. In other words, holes 76-80 are provided so that the angle β of second display unit 16 is 0 degrees, 5 degrees, 10 degrees, 15 degrees, and 20 degrees. Note that angle β and the number of holes 76-80 are not limited to those described above.

[0024] The lower fixing portion 70 includes a member 82. The member 82 is provided at the bottom of the rotatable second left frame 14b. The member 82 can move on a plate 87 as the second left frame 14b rotates. The member 82 is provided with a hole 84. Meanwhile, the plate 87 is provided with holes 76 to 80. The holes 76 to 80 are provided on the trajectory of the hole 84 that moves along the plate 87. Therefore, the member 82 is fixed to the plate 87 by overlapping the hole 84 with one of the holes 76 to 80 of the plate 87. The hole 84 of the member 82 and each of the holes 76 to 80 of the plate 87 may be fastened with a bolt or the like. A user of the display device 10 can use the lower fixing portion 70 to fix the second display unit 16 to the plate 87 at a desired angle.

[0025] The lower fixing portion 70 has stoppers 85 and 86 that protrude upward from a plate 87. In this embodiment, the stopper 85 is provided in front of the hole 75, and the stopper 86 is provided behind the hole 80. By protruding upward from the plate 87, the stoppers 85 and 86 serve as stoppers for the members 82 and 81. This allows the stoppers 85 and 86 to limit the range of movement of the first left frame 13b and the second left frame 14b. Note that in this embodiment, the stoppers 85 and 86 are provided on the plate 87, but they may also be provided on the beams 22, for example.

[0026] FIG. 6 is a plan view of the display device 10. FIG. 7 is an exploded view illustrating the upper fixing portion. The display device 10 has an upper fixing portion 30 that fixes the first display unit 15 and the second display unit 16. The upper fixing portion 30 has a hole 31 in the first display unit 15, a hole 32 in the second display unit 16, holes 34 and 35 in the beam 12, and brackets 40, 50, and 60. The hole 31 is provided on the plane of the first display unit 15, and the hole 32 is provided on the plane of the second display unit 16. The holes 34 and 35 are provided on the bottom surface (rear surface) of the beam 12. The holes 34 and 35 are provided on the bottom surface of the beam 12 on the side facing the support 11b.

[0027] The display device 10 includes a control unit, a power supply unit, a battery, a remote control receiver, etc. (not shown). The display device 10 also includes a separate remote control. The control unit receives an operation signal from the remote control received by the remote control receiver and performs processes such as switching the display content to be displayed on the first display unit 15 and the second display unit 16, setting a display schedule, or reading externally created display data.

[0028] FIG. 8 is a perspective view of the bracket 40, FIG. 9 is a front view of the bracket 40, FIG. 10 is a plan view of the bracket 40, and FIG. 11 is a side view of the bracket 40. The bracket 40 has an attachment portion 41, a connection portion 42, and a fixing portion 43. Next, the attachment of the bracket 40 to the second display unit 16 will be described. The attachment portion 41 is fixed to the hole 35 of the beam 12, and the fixing portion 43 is fixed to the second display unit 16. Specifically, the fixing portion 43 has a fixing hole 49. When the fixing hole 49 is aligned with the hole 32 of the second display unit 16 and fastened with a bolt or the like, the bracket 40 can be fixed to the display unit 16. The fixing portion 43 is also used when connecting brackets 50 and 60, which will be described later. Furthermore, the connecting portion 42 of the bracket 40 is used when connecting brackets 50 and 60, which will be described later. The connecting portion 42 has a connecting hole 44, a hole 45, and a hole 46. Furthermore, connecting portion 42 has bending portion 42h. By providing bending portion 42h, bracket 40 is strengthened. Display device 10 is intended for outdoor use. Bend portion 42h makes bracket 40 less likely to bend even if display units 15, 16 are blown by strong winds or the like.

[0029] The mounting portion 41 has a mounting hole 48. By aligning the mounting hole 48 with the hole 35 provided in the beam 12 and fastening it with a bolt or the like, the bracket 40 can be fixed to the beam 12. Here, the length L9 from the bottom surface (rear surface) of the beam 12 to the plane of the second display unit 16 is (Fig. 1). The mounting portion 41 has a rising portion 41h. The height direction length L10 of the rising portion 41h is set to be the same as the length L9 (Fig. 1) from the bottom surface (rear surface) of the beam 12 to the plane of the second display unit 16. When attaching the bracket 40, even if the heights of the second display unit 10 and the bottom surface of the beam 12 differ (even if the length L9 occurs), the bracket 40 has the rising portion 41h, so the beam 12 and the first display unit 15 can be connected.

[0030] 9 is set to be equal to or shorter than half the length L8 of the beam 12 in the front-to-rear direction shown in FIG. 7. This prevents the connecting portions 41 of the brackets 40 from coming into contact with each other even when the brackets 40 are attached to the holes 34, 35 of the beam 12.

[0031] FIG. 12 is a perspective view of bracket 50, FIG. 13 is a front view of bracket 50, FIG. 14 is a plan view of bracket 50, and FIG. 15 is a side view of bracket 50. Bracket 50 is connected to bracket 40 for use. Bracket 50 has connecting portion 52 and fixing portion 53. Connecting portion 52 has multiple holes 54, 55, 56, and 57. When bracket 50 is used by stacking bracket 40 on bracket 40, the length L2 between holes 54, 55, 56, and 57 is the same as the length L1 between holes 44, 45, and 46 of bracket 40 so that the holes of bracket 40 overlap. Width 52w of connecting portion 52 is wider than outer width 42w of connecting portion 42 of bracket 40. By setting width 52w of connecting portion 52 wider than width 42 of connecting portion 42 of bracket 40, bracket 50 can be stacked on bracket 40. Connecting portion 52 has bent portion 52h. Bracket 50 has bent portion 52h, which gives it a U-shaped cross section. Bent portion 52h increases the strength of bracket 50. Bent portion 52h makes bracket 50 less likely to bend even if display units 15, 16 are blown by strong winds, etc.

[0032] Fixing portion 53 of bracket 50 is provided with fixing holes 59. When fixing holes 59 are aligned with holes 32 on the plane of second display unit 16 and fastened with bolts or the like, bracket 50 can be fixed to second display unit 16. Furthermore, when bracket 50 is used by overlapping bracket 60, fixing holes 59 also serve as holes for connecting bracket 50 to bracket 60.

[0033] FIG. 16 is a front view of bracket 60, FIG. 17 is a plan view of bracket 60, and FIG. 18 is a side view of bracket 60. Bracket 60 has a connecting portion 62 and a fixing portion 63. Connecting portion 62 has a plurality of holes 64, 65, 66, and 67. Brackets 40, 50, and 60 can be stacked together. Therefore, the length L3 between holes 64, 65, 66, and 67 of bracket 60 is the same as the length L1 between holes 44, 45, 46, and 49 of bracket 40 and the length L2 between holes 54, 55, 56, 57, and 59 of bracket 50. By making lengths L1, L2, and L3 the same, brackets 40, 50, and 60 can be stacked together. The lengths of brackets 40, 50, and 60 can be changed by stacking them together. Furthermore, when the second display unit 16 is in a closed state, the length L4 from the hole 48 in the mounting portion 41 of the bracket 40 shown in Figure 10 to the hole 46 in the connection portion 42 is the same as the distance (length) from the hole 32 in the second display unit 16 to the hole 35 in the beam 12.

[0034] Furthermore, the outer width 62w of the connecting portion 62 is wider than the outer width 521w of the connecting portion 52 of the bracket 50. This wider width allows the bracket 60 to be stacked on top of the bracket 50. The connecting portion 62 has a bent portion 62h. The bracket 60 has a U-shaped cross section due to the bent portion 62h. The bent portion 62h increases the strength of the bracket 60. Therefore, even if the display units 15, 16 are blown by strong winds, the bracket 60 is less likely to bend.

[0035] Bracket 40 has connecting portion 42, bracket 50 has connecting portion 52, and bracket 60 has connecting portion 62. By providing connecting portions 42, 52, and 62, for example, when bracket 50 is to be placed on bracket 40, connecting portion 42 of bracket 40 can be slid between bent portions 52 of bracket 50. Because bracket 50 has bent portion 52h, bracket 50 can be easily placed on bracket 40.

[0036] The diameters of holes 44, 45, and 46 of bracket 40, holes 54, 55, 56, and 57 of bracket 50, and holes 64, 65, 66, and 67 of bracket 60, and fixing holes 49, 59, and 69 are all the same. When brackets 40, 50, and 60 are stacked and fixed, the same diameters allow the overlapping brackets 40, 50, and 60 to be fixed together. Furthermore, because the diameters of fixing holes 49, 59, and 69 are the same, no gaps are created between the brackets when, for example, a bolt is inserted into the holes. Therefore, when brackets 40, 50, and 60 are stacked and used, the brackets do not wobble.

[0037] Furthermore, the width 42w of the connecting portion 42 of the bracket 40, the width 52w of the connecting portion 52 of the bracket 50, and the width 62w of the connecting portion 62 of the bracket 60 are set to 42w < 52w < 62w. This prevents the user from stacking the brackets 40, 50, and 60 in the wrong order. Furthermore, the width 52w of the connecting portion 52 is set to be the same as or slightly wider than the outer width 42w of the connecting portion 42. This prevents the bracket 50 from wobbling when stacked on top of the bracket 40. The width 62w of the connecting portion 62 is set to be the same as or slightly wider than the outer width 521w of the connecting portion 52. This prevents the bracket 50 from wobbling at the connecting portion 62 of the bracket 60 when stacked on top of the bracket 50.

[0038] The display device 10 is provided with brackets 40, 50, and 60 for fixing the first display unit 15 to the beam 12. The brackets 40, 50, and 60 for fixing the first display unit 15 are similar to the brackets 40, 50, and 60 for fixing the second display unit 116 to the beam 12, and therefore a description thereof will be omitted.

[0039] Next, a method for fixing the first display unit 15 and the second display unit 16 of the display device 10 will be described. FIG. 19 is a diagram illustrating the first display unit 15 and the second display unit 16 in a closed state (when the angles α and β are 0 degrees). When the first display unit 15 is closed, the user aligns the hole 71 of the lower fixing portion 70 with the hole 83 of the member 81. The user can fix the first display unit 15 to the plate 87 by fastening the overlapping holes 71 and 83 with a bolt or the like. When the second display unit 16 is closed, the user aligns the hole 76 of the lower fixing portion 70 with the hole 84 of the member 82. The user can fix the second display unit 16 to the plate 87 by fastening the overlapping holes 76 and 84 with a bolt or the like. The user of the display device 10 can fix the first display unit 15 and the second display unit 16 to the plate 87 using the lower fixing portion.

[0040] The first display unit 15 and the second display unit 16 are each fixed to the beam 12 via the bracket 40 by the upper fixing portion 30. Specifically, the user aligns the hole 34 in the beam 12 with the hole 48 in the mounting portion 41 of the bracket 40 and fastens them together with a bolt or the like. Next, the fixing hole 43 in the bracket 40 aligns with the hole 15 in the first display unit 15 and fastens them together with a bolt or the like. The user can then fix the first display unit 15 to the beam 12 via the bracket 40. Because the length from the hole 31 in the first display unit 15 to the hole 34 in the beam 12 is equal to the length L4 of the bracket 40, the hole 34 in the beam 12 and the hole 46 in the bracket 40 are perfectly aligned. Furthermore, the length L6 from the hole 46 in the connecting portion 42 to the end of the fixing portion 43 is set shorter than the length L7 from the hole 31 in the first display unit 15 in the forward direction. Therefore, when the first display unit 15 in the closed state is fixed to the beam 12, the fixing portion 43 of the bracket 40 does not protrude from the first display unit 15. In this way, the user can fix the first display unit to the beam 12 via the bracket 40. The method for fixing the second display unit 16 to the beam 12 via the bracket 40 is similar to the method for fixing the first display unit 15 to the beam 12, so a description thereof will be omitted.

[0041] The longitudinal length L9 of the mounting portion 41 (FIG. 9) is half the length L8 (FIG. 7) of the beam 12 in the front-to-rear direction. This ensures that when the first display unit 15 and the second display unit 16 are fixed to the beam 12 via their respective brackets 40, the mounting portions 41 of the brackets 40 do not come into contact with each other. The mounting portions 41 and the fixing portions 43 of the brackets 40 are also rounded. This prevents a user of the display device 10 from being injured by the corners between the mounting portions 41 and the fixing portions 43.

[0042] FIG. 20 shows the first display unit 15 and the second display unit 16 when their rotation angles α and β are 5 degrees. When the first display unit 15 rotates at an angle α of 5 degrees, the user aligns the hole 83 of the member 81 of the first display unit 15 with the hole 72 of the lower fixing part 70. The user fastens the holes 83 and 72 with a bolt to secure the first display unit 15 to the plate 87. When the second display unit 16 rotates at an angle β of 5 degrees, the user aligns the hole 84 of the member 82 of the second display unit 16 with the hole 77 of the lower fixing part 70. The user fastens the holes 84 and 77 with a bolt to secure the second display unit 16 to the plate 87. The user can secure the first display unit 15 and the second display unit 16 to the plate 87 using the lower fixing part 70.

[0043] Furthermore, the first display unit 15 and the second display unit 16 are fixed to the beam 12 by the upper fixing portion 30. Specifically, the user places the bracket 40 on top of the bracket 50. Because the width 52w of the bracket 50 is slightly larger than the outer width 42w of the bracket 40, the bracket 40 fits snugly on the bracket 50. Next, the user places the hole 44 of the bracket 40 on the hole 54 of the bracket 50. Here, the length L1 between the holes 44 to 46, 49 of the bracket 40 is the same as the length L2 between the holes 54 to 57, 59 of the bracket 50. Therefore, the holes 44 to 46, 49 of the bracket 40 and the holes 54 to 57, 59 of the bracket 50 fit snugly on each other. That is, when hole 44 of bracket 40 and hole 54 of bracket 50 overlap, hole 45 of bracket 40 and hole 55 of bracket 50 overlap, hole 46 of bracket 40 and hole 56 of bracket 50 overlap, and hole 49 of bracket 40 and hole 57 of bracket 50 overlap. For example, a user can fasten holes 44 and 54, and holes 46 and 56 with bolts to secure brackets 40 and 50. Brackets 40 and 50 then become a single bracket 100.

[0044] The user can fix the bracket 100 to the beam 12 by aligning the mounting hole 48 of the bracket 100 with the hole 34 of the beam 12 and fastening them with a bolt. The user can also fix the bracket 100 to the first display unit 15 by aligning the hole 59 of the fixing portion 53 of the bracket 100 with the hole 31 provided in the plane of the first display unit 15 and fastening them with a bolt. In other words, the first display unit 15 is fixed to the beam 12 via the bracket 100. In this way, when the rotation angle α of the first display unit is 5 degrees, the first display unit 15 is fixed to the beam 12 via the bracket 100 (40, 50). Note that when the rotation angle β of the second display unit 16 is 5 degrees, the method of fixing the second display unit 16 to the beam 12 is the same as the method of fixing the first display unit 15 to the beam 12, so a description thereof will be omitted.

[0045] 21 is a diagram showing the case where the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are both 10 degrees. When the rotation angle α of the first display unit 15 is 10 degrees, the user aligns the hole 83 of the member 81 of the first display unit 15 with the hole 73 of the lower fixing part 70 and fastens them with a bolt. This fixes the first display unit 15 to the plate 87. When the rotation angle β of the second display unit 16 is 10 degrees, the user aligns the hole 78 of the lower fixing part 70 with the hole 84 of the member 82 of the second display unit 16 and fastens them with a bolt. When the hole 78 and the hole 84 are fastened together, the second display unit 16 is fixed to the plate 87. When the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are each 10 degrees, the rotating first display unit 15 and second display unit 16 are fixed to the plate 87 by the lower fixing part 70.

[0046] Furthermore, when the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are each 10 degrees, the first display unit 15 and the second display unit 16 are fixed to the beam 12 by the upper fixing part 30. Specifically, the user places the bracket 40 on the bracket 50. At this time, the hole 46 of the bracket 40 is aligned with the hole 54 of the bracket 50. The length L1 between the holes 44-46 and 49 of the bracket 40 is the same as the length L2 between the holes 54-57 and 59 of the bracket 50d. Therefore, when the hole 46 of the bracket 40 is aligned with the hole 54 of the bracket 50, the hole 49 is aligned with the hole 55. When the user fastens the holes 46 and 54 and the holes 49 and 55 with bolts, the brackets 40 and 50 become a single bracket 101. When the user aligns the mounting holes 48 of the combined bracket 101 with the holes 34 of the beam 12 and fastens them with a bolt, the bracket 101 is fixed to the beam 12. When the user aligns the fixing holes 59 of the bracket 101 with the holes 31 of the first display unit 15 and fastens them with a bolt, the bracket 101 is fixed to the first display unit. In this way, when the rotation angle α of the first display unit 15 is 10 degrees, the first display unit is fixed to the beam 12 via the bracket 101. When the rotation angle β of the second display unit 16 is 10 degrees, the method of fixing the second display unit 16 to the beam 12 is the same as the method of fixing the first display unit 15 to the beam 12, so a description thereof will be omitted.

[0047] FIG. 22 is a diagram showing the case where the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are both 15 degrees. When the rotation angle α of the first display unit 15 is 15 degrees, the user aligns the hole 83 of the member 81 of the first display unit 15 with the hole 74 of the lower fixing part 70 and fastens them with a bolt. This fixes the first display unit 15 to the plate 87. When the rotation angle β of the second display unit 16 is 15 degrees, the user aligns the hole 79 of the lower fixing part 70 with the hole 84 of the member 82 of the second display unit 16 and fastens them with a bolt. This fixes the second display unit 16 to the plate 87. When the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are both 15 degrees, the rotating first display unit 15 and second display unit 16 are fixed to the plate 87 by the lower fixing part 70.

[0048] When the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are both 15 degrees, the first display unit 15 and the second display unit 16 are fixed to the beam 12 by the upper fixing part 30. Specifically, the user places the bracket 40 on the bracket 50 so that the hole 46 of the bracket 40 and the hole 54 of the bracket 50 are aligned. The user then fastens the hole 46 of the bracket 40 to the hole 54 of the bracket 50 with a bolt. This secures the brackets 40 and 50 in place. Next, the user places the bracket 60 on top of the brackets 40 and 50. The width 62w of the bracket 60 (FIG. 17) is slightly larger than the outer width 521w (FIG. 15) of the bracket 50. Therefore, the bracket 60 fits snugly on the bracket 50. After placing brackets 40 and 50 on bracket 60, the user aligns hole 64 of bracket 60 with hole 55 of bracket 50. Here, the length L1 between holes 44-46, 49 of bracket 40, the length L2 between holes 54-57, 59 of bracket 50, and the length L3 between holes 64-67 of bracket 60 are the same. Therefore, when brackets 40, 50, and 60 are stacked, if any holes overlap, the other holes also overlap. The user fastens hole 55 of bracket 50 (hole 49 of bracket 40 overlaps below bracket 50) to hole 64 of bracket 60 with a bolt, and brackets 40, 50, and 60 become a single bracket 102. The user then fastens holes 57 and 66, and holes 59 and 67 of bracket 102 with a bolt.

[0049] Next, the user aligns the mounting hole 48 of the bracket 102 with the hole 34 of the beam 12 and fastens it with a bolt. This fixes the bracket 102 to the beam 12. The user aligns the fixing hole 69 of the bracket 102 with the hole 31 provided in the plane of the first display unit 15 and fastens it with a bolt. This fixes the bracket 102 to the first display unit 15. In this way, when the rotation angle α of the first display unit 15 is 15 degrees, the first display unit 15 is fixed to the beam 12 via the bracket 102. Note that when the rotation angle β of the second display unit 16 is 15 degrees, the method of fixing the second display unit 16 to the beam 12 is the same as the method of fixing the first display unit 15 to the beam 12, so a description thereof will be omitted.

[0050] FIG. 23 is a diagram showing the case where the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are both 20 degrees. When the rotation angle α of the first display unit 15 is 20 degrees, the user aligns the hole 83 of the member 81 of the first display unit 15 with the hole 75 of the lower fixing part 70 and fastens them with a bolt. This fixes the first display unit 15 to the plate 87. When the rotation angle β of the second display unit 16 is 20 degrees, the user aligns the hole 84 of the member 82 of the second display unit 16 with the hole 80 of the lower fixing part 70 and fastens them with a bolt. This fixes the second display unit 16 to the plate 87. When the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are both 20 degrees, the rotating first display unit 15 and second display unit 16 are fixed to the plate 87 by the lower fixing part 70.

[0051] When the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are both 20 degrees, the first display unit 15 and the second display unit 16 are fixed to the beam 12 by the upper fixing part 30. Specifically, the user places the bracket 40 on the bracket 50 so that the hole 46 of the bracket 40 aligns with the hole 54 of the bracket 50. The user then fastens the holes 46 of the bracket 40 to the holes 54 of the bracket 50 with a bolt, and similarly fastens the holes 49 of the bracket 40 to the holes 55 of the bracket 50 with a bolt. This secures the brackets 40 and 50 in place. The user then places the bracket 60 on top of the brackets 40 and 50. The width 62w of the bracket 60 (FIG. 17) is slightly larger than the outer width 521w of the bracket 50 (FIG. 15). Therefore, the bracket 60 fits snugly on the bracket 50. The user fastens the brackets 50 and 60 together with a lap bolt so that the hole 57 of the bracket 50 is aligned with the hole 64 of the bracket 60, and fastens the brackets 50 and 60 together with a bolt through the hole 59 of the bracket 50 and the hole 65 of the bracket 60. Then, the brackets 40, 50, and 60 become a single bracket 103.

[0052] Next, the user aligns the mounting hole 48 of the bracket 103 with the hole 34 of the beam 12 and fastens it with a bolt. This fixes the bracket 103 to the beam 12. The user aligns the fixing hole 69 of the bracket 103 with the hole 31 provided in the plane of the first display unit 15 and fastens it with a bolt. This fixes the bracket 103 to the first display unit 15. In this way, when the rotation angle α of the first display unit 15 is 20 degrees, the first display unit 15 is fixed to the beam 12 via the bracket 103. Note that when the rotation angle β of the second display unit 16 is 20 degrees, the method of fixing the second display unit 16 to the beam 12 is the same as the method of fixing the first display unit 15 to the beam 12, so a description thereof will be omitted.

[0053] In this embodiment, the rotation angle α of the first display unit 15 and the rotation angle β of the second display unit 16 are described as 0 degrees, 5 degrees, 10 degrees, 15 degrees, and 20 degrees. The display device 10 includes hinges 17 on the first display unit 15 and the second display unit 16. Therefore, for example, when the rotation angle α of the first display unit 15 is 5 degrees and the rotation angle β of the second display unit 16 is 20 degrees, the first display unit 15 can be fixed to the beam 12 using brackets 100 (40, 50), and the second display unit 16 can be fixed to the beam 12 using brackets 103 (40, 50, 60). In this way, even when the display device 10 is installed at a corner such as a T-junction or a Y-junction, the display units can be easily viewed from various directions by changing the rotation angles of the first display unit 15 and the second display unit.

[0054] The first display unit 15 and the second display unit 16 each rotate by means of the hinge 17. The first display unit 15 and the second display unit 16 are fixed to the beam 12 by the upper fixing unit 30. The first display unit 15 and the second display unit 16 are fixed to the holes 71 to 75 and the holes 76 to 80 of the plate 87 by the lower fixing unit 70. Therefore, even when the display device 10 is installed at a corner such as a T-junction or a Y-junction, the angle at which the display units 15 and 16 rotate can be changed to match the angle of the road, making the display units easily visible to passersby.

[0055] In addition, in this embodiment, it has been described that the holes 34, 35 are provided on the bottom surface (rear surface) of the beam 12. However, this is not restrictive, and the holes 34, 35 may be provided on the flat surface of the beam 12. In this case, the length of the rising portion 41h of the bracket 40 should be the length L9 from the bottom surface of the beam 12 to the flat surface of the first display unit 15 plus the length of the beam 12 in the height direction (the thickness of the beam 12).
