[Problems to be solved by the invention]
The conventional signage frame has the following problems.
(1) Angle materials have low torsional strength and are likely to be distorted or deformed. In particular, in the case of a signboard installed outdoors, distortion and deformation are likely to occur in the signboard frame due to the influence of wind.
(2) Welding angle materials on site requires a lot of labor, manpower and time, and it often takes several days to construct one signboard.
(3) Since skilled techniques are required for the welding operation, the number of people who can produce signboard frames is limited.
(4) Rust is likely to occur at the weld, and once rust occurs, it expands to the surroundings.
[0004]
[Means for Solving the Problems]
An object of the present invention is to provide a signboard frame that has sufficient strength, is resistant to rust, and requires less labor and time for manufacturing.

A pair of parallel long intermediate members 4c and 4c and 4d and 4d are also connected to each other by two or more reinforcing metal fittings 40.
[0015]
When a signboard is constructed using the signboard frame having the above-described structure, the frame body 1 is assembled by connecting the corner members 3a to 3d and the intermediate members 4a to 4d at a construction site or a factory. A post 2 is manufactured by attaching a column 2 to the body 1. Next, the base 22 of the column 2 is bolted to the base (column), and the display panel is attached to the frame 1. Moreover, when constructing an illumination signboard in which the display panel is illuminated from the inside, the display panel is attached after installing necessary devices such as a fluorescent lamp and a ballast in the assembled frame 1. In addition, when installing the required equipment for illumination, an angle etc. are arrange | positioned in the frame 1 as needed, and, thereby, a required equipment is installed in a predetermined position.
[0016]
(Embodiment 2)
Although the frame body shown in Embodiment 1 is a horizontally long rectangle, it can be formed into a vertically long rectangle or a square by changing the length of the intermediate member. Further, instead of a single intermediate member that connects a pair of adjacent corner members, a plurality of intermediate members that are connected may be connected. In this case, it is desirable to employ the same structure as the connection structure between the corner member and the intermediate member for the connection between the intermediate members.
[0017]
As long as the corner member and the intermediate member are plated on both inside and outside, the plating material may be other than zinc. Further, the dimensions of the corner member, the intermediate member, and other members are merely examples, and the present invention is not limited thereto.
[0018]
【The invention's effect】
(1) Since the corner member and the intermediate member constituting the frame body are formed of square pipes that are resistant to twisting, there is no problem that the frame is distorted or deformed by wind or its own weight.
(2) When a square pipe is used, rust is likely to occur on the inner surface that cannot be painted. However, in the signboard frame of the present invention, the inner and outer surfaces of the corner member and the intermediate member are plated, so that rust hardly occurs. In addition, the construction period is shortened because no painting work is required on site. Furthermore, since no painting equipment or painting technology is required, the production cost can be kept low.
(3) Since the frame can be assembled and disassembled, it can be manufactured without welding equipment and welding technology, and the construction period is shortened. Further, since the welding equipment and the welding technique are not required, the manufacturing cost can be further reduced. Furthermore, corner members, intermediate members, and other necessary members can be transported to the site and manufactured on the spot, thereby reducing transportation costs. In addition, since welding is not used for assembling, there is no problem that rust is generated at the welded portion and the rust expands to the whole.
(4) Since the frame can be assembled and disassembled, the signboard can be easily removed and disassembled in a short time.
(5) When the size or shape of the signboard needs to be changed in the future, it is possible to realize a signboard whose size or shape has been changed by reusing most of the members.
(6) In general, a signboard having sufficient strength and resistant to rust can be realized in a short period of time and at a low cost.
