[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a signboard structure used as, for example, a storefront exterior sign such as a convenience store.
[0002]
[Prior art]
Conventionally, as shown in FIG. 8, a billboard structure used for a storefront exterior sign such as a convenience store is a metal storage box 100 such as aluminum for storing a light source 103 such as a fluorescent lamp, and a frame for storing an acrylic face plate 102. 101 and a milky white acrylic face plate 102, and the frame 101 is configured to be detachable from the storage box 100 in order to install or replace the light source 103 or to replace the damaged acrylic face plate 102. Is common.
[0003]
[Problems to be solved by the invention]
However, the above-described conventional signboard structure has the following problems.
That is,
(1) Since the storage box 100 is made of metal, the weight is large. Therefore, when the storage box 100 is attached or removed for replacement, the work becomes large, which requires not only a lot of time and labor, but also a heavy object. Therefore, it is necessary to work without dropping it on the ground from the viewpoint of safety, which inevitably increases the number of work steps, and thus requires more time and labor.
(2) The frame 101 is usually made of aluminum and is similarly heavy. In the design as a signboard, the outer shape is restricted by the shape of the frame 101, so the outer shape can be designed freely. Cannot be done, it becomes a uniform one that receives a square and flat impression. Since the four sides of the peripheral side of the signboard are blocked by the frame 101, the peripheral side cannot be used as an effective display part (conventionally, the surface of the acrylic face plate 102 is printed or given some uneven shape. However, since the outer shape cannot be freely selected and the peripheral side surface cannot be used as the display portion, the degree of freedom in design must be reduced. , Poor gaze)
(3) Since the signboard structure is fixed by screwing, the replacement work for mounting and replacement is very complicated and cannot be performed efficiently.
It had the problem that.
[0004]
The present invention has been made in view of such a technical background. Therefore, the object of the present invention is lightweight, requires less time and labor for attachment and detachment, and has a high degree of freedom in design selection. The objective is to provide a signboard structure with excellent impression and gaze.
[0005]
Another object of the present invention is to provide a signboard structure that can be easily attached and detached in a shorter time.
[0006]
[Means for Solving the Problems]
The signboard structure according to the invention of claim 1 is a board-shaped hollow molded body in which a signboard body including a signboard face plate is integrally molded using a light-transmitting thermoplastic resin. A recessed portion for light source arrangement projecting inwardly and a fixing portion to the wall surface side are formed on the rear wall on the wall fixing side, and a light source is arranged in the concave portion, and the fixing portion is arranged on the back surface.
