Description

MOUNTING BRACKET FOR SIGN BOARD}

The present invention relates to a stereolithography fastener, and more particularly, it relates to a stereolithographic fastener for fixing a top plate or a bottom plate to a side frame without assembling screws or welding, Thereby improving the fixation force and preventing the clearance between the upper plate or the lower plate and the side frame, thereby improving the appearance and reliability of the product.

A stereoscopic signboard is a signboard that is installed to inform the consumers of business places or business contents such as a company or a shop.

Such stereoscopic signboards must have differentiated identification or visibility so that the consumers can easily recognize the contents, and an illuminating device for enabling the consumers to be seen not only in the daytime but also in the nighttime is indispensably provided.

4, the stereoscopic signboard 100 includes a tubular side frame 120 with both open ends and an upper panel (not shown) mounted on the upper side of the side frame 120 An upper cover 135 for sealing the upper panel 130 and the side frame 120 and a base module 140 mounted with the illumination unit 160.

The side frame 120 is formed with a locking part 125 for fixing the upper panel 130 and the base panel 140. The locking part 125 may be integrally formed by bending the side frame 120, Or extrusion or the like.

Then, when the upper panel 130 is fixed to the side frame 120, the upper panel 130 is fixed using a welding method, a taka method, or a method of bonding using a resin such as silicone.

The welding method is advantageous in that the inside is clean and external impurities do not permeate at the time of installation. However, since the welding operation must be performed at the corners where the engaging portion and the upper panel are in contact with each other in the narrow side frame, There is a problem that welding is difficult, and even in such a case, there is a problem that the working environment is not easy and there are many defects. Therefore, there is a problem that the labor cost increases, the cost increases, and the productivity decreases.

In the case of the taka system, although the workability is relatively easier than the welding method, the upper panel is mechanically fixed through the engaging portion and the upper panel. Therefore, in the case of the upper panel made of acrylic or the like having a high hardness, .

In addition, in the case of the above-mentioned bonding method, the side frame, which is made of a metal, and the upper panel made of a synthetic resin are different from each other in physical properties, and adhesiveness is poor.

Further, all of the above-described methods are repeatedly exposed at a high temperature and a low temperature due to the characteristics of the stereolithography board 1 provided outside, and the thermal expansion coefficients of the interlocking fixed portion (metal material) and the upper panel (synthetic resin) This causes a problem of distortion or separation (separation).

This has a problem in that not only the durability of the stereoscopic signboard itself is lowered but also water or foreign matter enters between the separated gaps to cause a malfunction or a safety accident of the illuminating part.
