Description

A cloth fixed device of signboard frame}

The present invention relates to a fabric fixing device of the signboard, and more particularly to a fabric fixing device of the signboard frame that can be used when fixing the fabric of the signboard frame can perform a number of roles.

In general, the signboard is intended to be easily visually visible, and is installed vertically with respect to the signboard attaching surface so that it can be seen from both sides, and the back surface is closely attached to the attaching surface. .

The structure of such a signboard is usually composed of a signboard frame and a cloth. The signboard frame is made of a material such as aluminum, and is made of a square, a circle, and the like, and can be equipped with a lighting fixture inside.

In addition, the fabric is fixed to the signboard so as to visually display the shape, shape, color, etc. of symbols, characters, etc. to be displayed, such fabric is usually a synthetic resin material coated on the front and rear surfaces, and the fiber yarn inside It intersects horizontally and vertically.

Therefore, by fixing the entire edge of the fabric along the ceiling portion formed in the signboard frame, the fabric is maintained and fixed at a constant tension on the front and back, or one side of the signboard.

Referring to FIG. 1, a method of fixing a cloth to a conventional signage frame will be described.

As shown in FIG. 1, the conventional signage frame is formed with a ceiling fixed end 2 curved at an upper end thereof, and one side end of the cloth 3 adheres closely to the side surface of the ceiling fixed end 2, and then an air compressor. Using a portable air stapler (4) connected to the fixed and fixed to the opposite end of the fabric (3), one end is pulled in close contact with the forceps and the like so as to have a predetermined tension toward the opposite fabric fixing end (2) If the other person shoots again using the stapler 4, the other end of the cloth 3 is also fixed.

When the cloth is maintained at a constant tension on the signboard frame and fixed in the same manner as described above, various characters, etc., to be displayed thereon are written and designed.

However, the fabric fixing method as described above uses forceps and the like because it is difficult to do it by hand to pull the fabric. These tongs have been designed to bite the fabric along with the signboard because the tongs directly damage the fabric.

However, even when using tongs, only one piece of cloth pulls a certain area of fabric, so after a few staples, there is an inconvenience of having to remove it and move it to the side again. Accordingly, it may be used after fixing it over the entire length of the signboard frame using several tongs.

However, considering the size of the signboard, the number of tongs to be used to make a signboard will be enormous. For example, only one tong can be stapled to the fabric by 150 to 200 mm (10 to 20 cm). Then, assuming that 5m (5000mm) signboards are commonly used, the total number of tongs used is about 20 to as many as 35.
