Description

Multi-function signboard

The present invention relates to a multifunctional billboard, and more particularly, to maintain a stable erected form without tilting the frame structure of the banner billboard, which is configured to easily and conveniently install and move banners such as banners displaying advertisement contents, At the same time, it is improved to allow wind to pass through, so that it does not easily fall over in strong wind even when any heavy body is combined, and disassembly and assembly are simple, so it is easy to install and disassemble, as well as good storage and portability, and can be used regardless of indoors and outdoors. It is related to a multifunctional standing signboard invented to be used for hanging various objects as well as banners having any shape.

Commonly known outdoor advertisements include signboards protruding from the outer wall of a building and billboards or banners installed to be located in pedestrian passages, and advertisements in which pedestrians are written by the signboards, billboards, banners, etc. It is to make it easy to observe the advertisement through the eyes.

The conventional banner support device related to this technology is attached to the wall of the building or the banner is connected to the upper and lower sides of the horizontal fixing bar connected to the vertical support bar, respectively, and is positioned at the eye level of the pedestrian and at an appropriate position. that is going to have an effect.

However, the banner support device as described above makes it difficult to fix and remove the banner, as well as increases the fixing and removal time, and the banner support always maintains a certain shape, requiring a certain storage space and installation space, as well as transportation There are downsides to being uncomfortable.

On the other hand, recently, banner posts (or banner billboards) are 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 constructed so that it is not easily knocked over by the wind by putting a weight of water, and the banner bulletin board is widely used in stores in various fields because it is easy to move and has advantages such as low price, unlike fixed bulletin boards.

As a conventional banner support device, Korean Utility Model Registration 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 portion installed to be foldable by an elastic bar elastically connecting the support pieces; It has a form configured to include a banner fixing means installed on the support and fixing one side of the banner, and a banner support means connected to the support piece to support the other side of the banner.

In addition, the banner fixing means is made of a fixing hook connected to protrude from the outside of the support via a spring from the inside of the two supports among the plurality of supports, and the banner support means is formed with a fixing hole on the upper side of the support piece, respectively As it is inserted into the inside, it is made of a support bar having a fixing hanger at the top, and a locking piece having a transfer hole is installed in the remaining support of the plurality of supports to insert one side of the elastic bar.

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 inserted into the upper part of the support piece are standardized and connected, so the size of the advertising sheet that can be fixed is limited Therefore, 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 posts have a forward leaning structure, resulting in a lack of stability as well as a problem of being easily knocked over by the wind. Also, as a means to prevent banner posts from collapsing, most of the banner posts are hollow tubes lacking space to insert support rods It is impossible to add weight because it uses a shaped stand, and it is impossible to use it as an outdoor banner post without a stand filled with water or sand.

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

Here, looking at the representative types of conventional banner posts, vertical flags, X-shapes, and Y-shapes are used. It does not fall well compared to the J-shaped and Y-shaped bulletin boards.

However, in the case of the banner type, the banner rotates when the wind blows, so the advertising effect is lowered and the price competitiveness is lowered. In addition to losing effectiveness, there is a problem of causing safety accidents or causing inconvenience to people's passage.

The present invention has been devised to solve these conventional problems, and the frame structure of the banner signboard, which can easily and conveniently install and move banners such as banners displaying advertisement contents, is stably erected without leaning forward. It is formed to hold and at the same time allows wind to pass through, so it does not fall easily in strong wind, and it is possible to prevent falling by combining weights of any shape, and disassembly and assembly are simple, so installation and disassembly are easy. Of course, it has good storage and portability, can be used both indoors and outdoors, can be combined with banners of any shape, and can also be used for hanging various objects, greatly improving the usability of the product and its compatibility. Its purpose is to provide a multi-functional signboard that can
