Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a frame for placard,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banner, and more particularly, to a banner frame fastened to both sides of a banner in order to securely fasten both sides of the banner with a rope or the like.

A conventional banner is made of cloth or vinyl paper on which various advertisement texts and notices are described, and a through-hole is formed on both sides of the banner to be opened up and down so that a frame made of wood is fitted and projected upward and downward, One end of the rope is bound to the upper and lower portions of the rope so as to be horizontally or vertically positioned between the pair of postcards or between the various structures, .

This conventional banner is difficult to assemble because the rope is bound to the upper and lower protrusions of the frame made of wood. Even after the banner is assembled, the rope is loosened by external force such as strong wind, The frame protrudes from the upper and lower ends of the banner, and the rope is bound to the protruding portion. Therefore, when a strong wind blows, the frame made of wood is easily broken and the banner is broken or torn Which can result in a deterioration of the aesthetics of the streets and buildings where the banners are installed.

In addition, the above-mentioned conventional banner needs to be folded and sewed at the end of the banner, and it is troublesome to bond the banner through the screws or staples between the banner and the wooden frame after inserting the wooden frame And the installation time and labor cost are increased. In addition, the banners and their supports, which are removed after use, are incapable of being reused in most cases.
