Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a signboard that is attached to the outer wall of a building or other building.

[Conventional technology]

There are many places where billboards are attached to the exterior walls of buildings and other buildings to provide information and advertisements, such as the name of the company that is occupying the building. For example, a hard board made of wood, metal, or plastic is used, and advertising characters are written on the front and back sides of the board.

[Problem that the invention seeks to solve]

In this way, since a single plate-shaped member is used as the display body of the signboard, the size is almost permanently determined at the time of installation.

On the other hand, because signboards are installed protruding from the outside of buildings, they are susceptible to the effects of wind, especially on windy days like typhoons, and are subject to large wind pressures, which can cause the signboards to fall. It is a danger.

Furthermore, during transportation and installation, large plate-like members must be handled, which is inconvenient.

An object of the present invention is to eliminate the disadvantages of the conventional example, and to provide a signboard that is less susceptible to the effects of wind and the like, is safe, and is convenient to transport and handle.

[Means for solving problems]

In order to achieve the above object, the gist of the present invention is to attach a display body that expands and contracts by air pressure to a base.

[Effect]

According to the present invention, air is injected into the display body to inflate it, expand it, and project it outward from the outer wall of a building, etc., and on days when the wind is strong and the wind pressure is high, the air inside is evacuated and the display body is inflated and expanded. to reduce wind resistance.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a longitudinal sectional front view showing an embodiment of the signboard of the present invention;
The figure is a cross-sectional plan view of the same as above, and in the figure, 1 indicates a box-shaped base with a U-shaped cross section, and 2 indicates a translucent display body that is airtightly attached to the opening surface of the base 1. For example, the base 1 is made of a stretchable flexible material such as rubber so that it has a box shape with a U-shaped cross section when stretched, and advertising characters 10 such as a company name are written on the surface. and the display body 2 constitute the main body part A of the signboard.

The main body A of the signboard constructed in this way is attached to a tubular fixture 3.
It is fixed to the outside of the outer wall 5 of the building 4, and a blower 6 is separately provided, and an air supply/exhaust pipe 7 with a valve 8 installed in the middle is connected to this, and the air supply/exhaust pipe 7 is passed through the fixture 3. The tube end was communicated with the inside of the main body part A of the signboard.

Note that 9 in the figure indicates a lighting device such as a fluorescent lamp disposed within the base 1.

Next, to explain the usage and operation, the valve 8 is opened and the blower 6 blows air through the air supply and exhaust pipe 7 to the base 1 and the display body 2.
When the display body 2 is fed into the air, the display body 2 is expanded by the air and bulges into a box-like shape.

When the valve 8 is closed in this state, the display body 2 maintains its box shape and the advertisement characters 10 appear on the surface as shown in FIG.
The display body 2 serves as a signboard. Then, at night, when the lighting device 9 is turned on, the light rays emitted from it are transmitted to the outside through the semi-transparent display body 2, making the display body 2 stand out.

By the way, when the wind is strong and a large wind pressure is applied to the display body 2, the air inside the display body 2 is removed by opening the valve 8 or by reversing the air blower +M6, and the air is deflated as shown in Fig. 3. If the main body A of the signboard is placed in the opening of the base 1, the size of the main body A of the signboard will be approximately equal to the size of the base 1, and as a result, the wind pressure received here will be reduced.

In the above embodiment, the display body 2 is made of a material that expands and contracts itself, such as rubber, but the present invention is not limited to this, and the display body 2 may be formed into a bellows shape. Any structure that allows the display body 2 to expand and contract as a whole may be used.

〔Effect of the invention〕

As mentioned above, since the signboard of the present invention expands and contracts itself, it can freely change its capacity depending on the magnitude of wind pressure, etc., and prevents dangers such as falling due to wind on windy days. It is safe to use.

In addition, it is easy to handle because it can be contracted during transportation and installation (improving work efficiency, and it is lightweight even after it is installed on a building, so only weak mounting tools are needed). Since the load applied to the building is small, safety can be ensured in this respect as well.
In terms of cost, it is also inexpensive because it uses air.
