Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail for each example.

Example

[0012] (Overall Structure) Figure 1 is a perspective view showing an example of the assembled display board 12 of the present invention as assembled on the loading platform 16 of the truck 14. This assembled display board 12 has a structure in which several display board units 18 are stacked vertically and supported by vertical support columns 32. A pair of vertical clamps 34 are fixed to the rear tilt plate 30 of the truck 14, and the vertical support columns 32 are fixed to these, and the display board units 18 are connected and fixed thereon.

[0013] Furthermore, the display board units 18 are supported from the back using the horizontal support columns 38. A pair of horizontal clamps 40 are fixed to the side tilt plate 36 of the truck 14, and one end of the two horizontal support columns 38 is connected.

[0014] The horizontal support column 38 and the horizontal clamp 40 are connected by a flexible joint, and the horizontal support column 38 and the display board unit 18 are also connected by a flexible joint. Therefore, no matter where the display board units 18 are stacked, the fixed position of the horizontal clamp 40 can be adjusted to securely support the display board units 18 on the loading platform 16 of the truck 14 with a pair of horizontal support columns 38. The structure of the display board unit 18 will be described in FIG. 2, the connection structure of the vertical clamp 34 will be described in FIG. 3, and the structure of the horizontal clamp 40 will be described in FIG. 4.

[0015] Figure 2 is a block diagram showing an example of the internal structure of the display board unit 18. Inside the signboard unit 18, a power supply unit 20, a communication unit 22, a display control unit 24, and a display unit 26 are incorporated, and the whole is sealed. The communication unit 22, the display control unit 24, and the display unit 26 are driven by the power supply unit 20 equipped with a battery. For example, it is an electric bulletin board that can be used while charging or replacing the battery.

[0016] The communication unit 22 receives the data of the display image 29 from the remote controller 28 operated by the user, and displays the image on the display unit 26 under the control of the display control unit 24. In this way, the signboard unit 18 can freely select the image to be displayed by the remote controller 28. The assembled signboard 12 of the present invention can freely stack one, two, or three signboard units 18 to display a screen of any size. As a result, information for a construction site or road guidance can be displayed in detail.

[0017] FIG. 3 is a perspective view of the back surface 42 of two stacked signboard units 18 and the vertical struts 32 and vertical clamps 34 that support them. On the back surface 42 of the signboard unit 18, one rail 46 is fixed on each of the left and right sides. The periphery of the rail 46 has the same structure on the left and right. Since the drawing would become complicated, the overall structure of the right back is shown by a broken line, and only the front rail 46 and its peripheral structure are shown by a solid line.

[0018] A vertical clamp 34 is fixed to the rear spoiler 30 of the truck 14. By turning the handle 41, the square bar 33 integrated with the vertical strut 32 is pressed against the rear spoiler 30 side, and the vertical strut 32 is fixed so as to stand vertically. The structure of the handle 41 is the same as that attached to the horizontal clamp 40 described in FIG. 4.

[0019] On the rail 46 attached to the signboard unit 18, male and female column connectors 48 are attached to the upper and lower parts thereof, respectively. In the example of this drawing, the column connector 48 attached to the lower side of the uppermost signboard unit 18 is connected to the column connector 48 attached to the upper side of the lower signboard unit 18. Note that a thin pipe is inserted inside the thick pipe to form a male structure, and both pipes are fixed with screws 49. Screws 49 are also provided in the female structure part, and after connection, the screws 49 are tightened to fix the connected state.

[0020] And the column connector 48 attached to the lower side of the lower signboard unit 18 is connected to the vertical column 32. In this way, the columns of the two signboard units 18 are connected and fixed to the upper side of the vertical column 32. Note that a hinge 62 is fixed at the center of the rail 46 of the topmost signboard unit 18, which constitutes a signboard-side universal joint 54. The other end 56 of the horizontal column 38 is connected to this signboard-side universal joint 54 using a pin 53. FIG. 4 shows the connection structure on one end side of this horizontal column 38.

[0021] Note that the rail 46 is fixed to the back surface 42 of the signboard unit 18 in order to detachably fix the column connector 48 and the signboard-side universal joint 54. Each member can be slid along the rail 46 for positioning and fixed in advance, eliminating the need for on-site detachment and attachment work. Only the necessary parts need to be fixed. In the example of the drawing, a signboard-side universal joint 54 and a column connector 48 are fixed to the back surface 42 of the uppermost signboard unit 18, and there is no signboard-side universal joint 54 on the back surface 42 of the lower signboard unit 18, and column connectors 48 are fixed vertically. Since high strength is required for the column connector 48, the signboard-side universal joint 54, and the vertical clamp 34, they are made of SUS (stainless steel) or the like. The rail 46 and the horizontal column 38 can maintain sufficient strength even with an aluminum alloy or the like, and thus the weight can be reduced.

[0022] FIG. 4 is a perspective view showing the structure around the horizontal clamp 40 that connects the horizontal column 38. The horizontal clamp 40 is fixed to the lateral tilting plate 36 of the truck 14. The horizontal clamp 40 is fixed so as to clamp the lateral tilting plate 36 by turning the handle 41. A bearing 58 is fixed to the upper surface of the horizontal clamp 40. One end 52 of the horizontal support column 38 is connected to an arm welded to the side surface of a pipe 60 loosely fitted into the bearing 58 by using a pin 53. These constitute the clamp-side flexible joint 50.

[0023] With the clamp-side flexible joint 50, the horizontal support column 38 can be freely oriented both horizontally and vertically. Also with the signboard-side flexible joint 54 described with reference to FIG. 3, the horizontal support column 38 can be freely oriented both horizontally and vertically. As a result, the signboard unit 18 can be installed on both the rear tilting plate 30 and the lateral tilting plate 36, and no matter how many signboard units 18 are stacked, a pair of horizontal support columns 38 can be connected to the horizontal clamps 40 fixed to the rear tilting plate 30 or the lateral tilting plate 36 to support the signboard unit 18. Variations in the signboard position will be described with reference to FIG. 5.

[0024] FIG. 5 is a plan view showing an example of the arrangement of the assembled signboard 12 on the loading platform 16 of the truck 14. (a) shows an example in which the signboard unit 18 is arranged on the front side surface of the truck 14. In FIG. 1, it was arranged on the rear tilting plate 30 of the truck 14, so the horizontal clamps 40 were fixed to the left and right lateral tilting plates 36. On the other hand, in the example of (a), a pair of horizontal clamps 40 are arranged and fixed to the lateral tilting plate 36 on the side opposite to the signboard unit 18. Also according to the example of (b), the signboard unit 18 can be arranged on the rear side surface of the truck 14. For example, in order to increase the strength against wind etc., one horizontal clamp 40 can be fixed to the rear tilting plate 30 and the other horizontal clamp 40 can be fixed to the lateral tilting plate 36 to support the signboard unit 18.

[0025] (Function) As described with reference to FIG. 1, the assembled signboard 12 of the present invention can be transported in a state where the clamp, the support column, and the signboard unit are separated and assembled on site. Therefore, a dedicated vehicle equipped with a signboard is not required. Also, it is not necessary to arrange a professional driver to drive the dedicated vehicle. That is, it can be transported by a light truck 14 or the like that can be driven with a regular driver's license, and can be assembled on site on its loading platform 16. By preparing a plurality of signboard units 18 and stacking and connecting them, signboards of free sizes from small to large can be assembled on site.

[0026] As described with reference to FIG. 2, each signboard unit 18 has a function in which the image display mechanism is sealed and operates independently. By freely selecting the display image 29 with the remote controller 28, a plurality of signboard units 18 can be stacked, and free guidance displays and advertisement displays can be made according to the size. A large screen can be configured with a plurality of signboard units 18, and an image of a large screen with free vertical and horizontal dimensions can be configured. The display image of the large screen to be displayed on the plurality of signboard units 18 may be divided and transmitted to each signboard unit 18 and the display timings may be synchronized.

[0027] As described with reference to FIGS. 1 and 5, on the loading platform 16 of the truck 14, the vertical support column 32 can be fixed using the rear tilt plate 30 and the side tilt plate 36, and one or a plurality of signboard units 18 can be stacked and connected at an arbitrary location. Furthermore, the support strength of the stacked signboards can be increased by a pair of side support columns 38 and side clamps 40.

[0028] As described with reference to FIG. 3, since the support column connector 48 is attached to the back surface 42 of each signboard unit 18, a plurality of signboard units 18 can be freely stacked on top of or below each other and easily connected to the vertical support column 32.

[0029] As described with reference to FIGS. 3 and 4, one end 52 of the horizontal support column 38 is connected to the horizontal clamp 40 via the clamp-side flexible joint 50, and the other end 56 of the horizontal support column 38 is connected to the signboard unit 18 via the signboard-side flexible joint 54. Therefore, the height and position of the signboard unit 18 can be freely selected and easily and reliably supported and fixed. As a result, the loading platform 16 of the truck 14 can also be effectively utilized.

[0030] When using the assembled signboard 12 of the present invention, first, prepare the number of signboard units 18 corresponding to the size of the signboard to be adopted at the target construction site or the like and the display image data of each signboard unit 18. Further, determine the arrangement position and orientation of the signboard, and prepare the fixing position of the clamp and the horizontal support column 38 of the required length. It is also possible to mark the position where the clamp is to be fixed on the spoiler of the truck, or to fix the clamp in advance at the corresponding location of the truck. When arriving at the site, the signboard units 18 are stacked and then the horizontal support column 38 is connected, and the assembly is completed immediately.

[0031] In addition, since the support column connector 48 and the signboard-side flexible joint 54 are detachably fixed to the back surface 42 of the signboard unit 18, as shown in FIG. 3, the support column connector 48 at the upper part of the uppermost signboard unit 18 is excluded, and only the signboard-side flexible joint 54 is attached to this signboard unit 18. As a result, unnecessary parts can be excluded in advance to reduce the weight. Furthermore, forgetting to place or dropping parts and tools at the road construction site can also cause traffic accidents. Therefore, by simplifying the overall structure and simplifying the assembly work at the site as much as possible, safety can be achieved.

[0032] Note that the frame surrounding the image display section of the signboard unit 18 is made of a material with low strength for weight reduction. Therefore, vertical reinforcing rails 46 are attached to the left and right of the back surface 42. The cross-sectional shape of this rail 46 is arbitrary, but in the embodiment, it is also made of an aluminum alloy rail, which is a lightweight metal, as a reinforcing member in order to reduce the overall weight. And only the male and female column connectors 48 and the signboard-side flexible joints 54 are made of a high-strength metal such as stainless steel that is resistant to bending and twisting, and are externally fixed to both ends of the rail 46, thereby reducing the overall weight. With this structure, it has become possible to stack and connect multiple signboard units 18. Note that the vertical clamp 34 fixes the vertical column 32 by releasing the reinforcing square column 33 that prevents twisting, but a structure that directly fixes only the vertical column 32 may also be used.
