Description

multifunctional billboard

The present invention relates to a multi-functional billboard, and more particularly, to maintain the frame structure of a banner billboard configured to simply and conveniently install and move a banner such as a placard on which advertisement content is displayed, stably erected without leaning forward. At the same time, it is improved so that the wind can pass through it, so it does not fall over easily in strong winds no matter what weight is combined, and it is easy to install and disassemble due to simple disassembly and assembly, as well as good storage and portability, and can be used indoors or outdoors It is possible and relates to a multifunctional billboard invented so that it can be used for hanging various objects as well as banners having any shape.

Generally known outdoor advertisements include a signboard protruding from the outer wall of a building and a billboard or banner installed to be located in a pedestrian's driving path, and advertisements in which pedestrians are described by the signboard, billboard, and banner. It is to make it easy to observe the advertisements through the eyes.

The conventional banner support device related to such a technology is attached to the wall of a building or connected to the upper and lower sides of a horizontal fixing bar in which a banner is connected to a vertical support bar, and is fixed at the eye level of pedestrians and fixed at an appropriate position to provide a certain advertisement to bring about an effect.

However, the banner support device as described above not only makes it difficult to fix and remove the banner, but also increases the fixing and dismantling time, and the banner support always maintains a certain shape, requiring a certain storage space and installation space, as well as transportation. There is a downside to being uncomfortable.

On the other hand, in recent years, banner posts (or banner billboards) have been widely used to post banners made of fabric paper, resin sheets, etc. on which advertisement contents such as photos and texts are displayed. It is configured not to easily fall over by the wind by putting a weight of water, and the banner post is widely used in stores in various fields because it is easy to move and has advantages such as a low price, unlike a fixed post.

As a conventional banner support device, Korean Utility Model Publication No. 10-203062 has been proposed.

Such a banner support device includes a plurality of supports connected to both sides of the support piece, and a support part installed so as to be foldable by an elastic bar elastically connecting the supports; It has a form configured to include a banner fixing means installed on the support to fix one side of the banner, and a banner supporting means connected to the support piece to support the other side of the banner.

In addition, the banner fixing means is formed as a fixing hook that is connected to the outside of the support through a spring on the inside of the two supports among the plurality of supports, and the banner support means forms a fixing hole on the upper side of the support piece, It is made as a support bar having a fixed hook on the upper part while being inserted therein, and a locking piece having a transfer hole is installed on the other support of the plurality of supports, so that one side of the elastic bar is inserted.

However, in the banner support device as described above, the length of the two supports rotatably connected to the lower part of the support piece and the support bar respectively inserted into the upper part of the support piece are standardized and the size of the advertisement sheet that can be fixed is limited. There is a disadvantage in that it is not possible to easily fix advertisement sheets having various sizes.

In addition, most of the conventional banner post stands have a structure that leans forward, so they lack stability and easily fall over in the wind. It is impossible to add weight because it uses a pedestal in a shape, and it is impossible to use as an outdoor banner post without a pedestal filled with water or sand.

In addition, even when outdoor use is used indoors, it is inconvenient to have to fill the pedestal with water or sand, and the pedestal reduces portability. There is a problem of having to empty it or emptying it, and in particular, there is a problem that the banner post itself cannot be used for any other purpose.

Here, if we take a closer look at the typical types of banner posts in the prior art, vertical flag types, X-shaped and Y-shaped, etc. are used. It does not fall over easily compared to the Y-shaped and Y-shaped bulletin boards.

However, in the case of the flag type, as the banner rotates when the wind blows, the advertising effect is lowered as well as the competitiveness compared to the price. In addition to loss of effectiveness, there is a problem that causes a safety accident or inconveniences people's passage.
