Balloon-shaped metal lettering

Abstract

To provide balloon-shaped metal cut letters. [Solution] These are metal letters used for signs, decorations, etc., and are made by welding multiple metal plates together and applying internal pressure with gas or liquid to form an inflated shape. These metal cut letters have excellent weather resistance and durability for outdoor use and can be used for a long period of time. This is a device for adding weather resistance and durability to letter-shaped balloons used at events, etc., which are made by bonding two thin aluminum sheets together and filling the inside with air. By applying high internal pressure with gas or liquid to letters made of multiple metal sheets, this device is designed to reproduce a shape equivalent to a balloon made of two thin aluminum sheets bonded together and filled with air. This is a device for adding weather resistance and durability for outdoor use to letter-shaped balloons made of aluminum foil or polyethylene film used as decorations at events, etc.

Description

[Technical Field]

[0001] This invention relates to obtaining letter-shaped balloon-shaped cut letters that are weather-resistant for outdoor use and durable for long-term use on letter-shaped balloons made of aluminum foil or polyethylene film used as decorations at events, etc. [Background technology]

[0002] Letter-shaped balloons made of aluminum foil or polyethylene film, which are used as decorations at events, cannot withstand wind and rain outdoors, and over time the air inside the balloons escapes, meaning they cannot maintain their shape for long periods of time and are therefore discarded.

[0003] The applicant is not aware of any prior art related to the present invention at the time of filing this application. Summary of the Invention [Problem to be solved by the invention]

[0004] To obtain cut letters in the shape of letter balloons, which have weather resistance suitable for outdoor use and durability suitable for long-term use, for letter balloons made of aluminum foil or polyethylene film used as decorations at events, etc. [Means for solving the problem]

[0005] The metal cut letters are used for signs, decorations, etc., and are made by joining a plurality of metal plates by welding and forming them into a bulging shape by applying internal pressure with gas or liquid, thereby producing metal cut letters that are excellent in weather resistance and durable enough to be used outdoors for a long period of time. [Effects of the Invention]

[0006] The metal cut letters of this invention, when properly installed, will not change shape even when used outdoors for a long period of time, and do not need to be discarded in a short period of time like letter-shaped balloons made of aluminum foil or polyethylene film, and because they are made of metal, they are easy to recycle. [Brief explanation of the drawings]

[0007] [Figure 1] This is a diagram showing the state of the metal cut-out letters of the present invention before two metal plates are joined together. [Figure 2] 1 is a diagram showing the metal cut-out letters of the present invention after two metal plates are joined together. [Figure 3] This is a diagram showing the state of the metal cut-out letters of the present invention after two metal plates are joined together and then internal pressure is applied using gas or liquid to form them. [Figure 4] This is a diagram showing the intended shape of the cut metal letters of the present invention, showing the two metal plates before they are joined together. [Figure 5] This is a diagram showing the cut sheet of metal lettering related to the present invention before the two metal plates are joined together, taking into account the shape that will deform after forming. DETAILED DESCRIPTION OF THE INVENTION

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the balloon-shaped metal cut letter according to the present invention will be described with reference to the accompanying drawings.

[0009] Figure 1 shows the metal cut-out letters of this invention before the two metal plates are joined together. As shown in Figure 2, the upper and lower metal plates are joined together and internal pressure is applied using gas or liquid.

[0010] Figure 3 shows the state after molding by applying internal pressure using gas or liquid.

[0011] During the forming process shown in Figure 3, some shapes may be deformed and not become the intended shape. In the case of the intended shape shown in Figure 4, the intended shape can be obtained after forming by joining and forming sheet materials in the shape shown in Figure 5, anticipating the deformation.

[0012] In order to prevent deformation during molding due to internal pressure caused by gas or liquid, reinforcing materials may be placed in areas where deformation is expected.

[0013] In some cases, the thickness of one of the two metal plates shown in Figure 1 is increased to take deformation into account, and the upper and lower plates are formed one side at a time and then joined after forming.

[0014] The joints of the tubes shown in Figures 2 and 3 for applying internal pressure using gas or liquid act as reinforcement during molding and may become areas that cannot be molded, so the locations where they are placed should be areas that will have minimal effect on the desired shape after molding. [Industrial Applicability]

[0015] The method for molding balloon-shaped metal cut letters according to the present invention can be applied to other purposes besides letters, and can be used in other industrial fields.

Claims

[Claim 1] These metal cut letters are used for signs, decorations, etc. and are made by welding together multiple metal plates and applying internal pressure with gas or liquid to form them into a bulging shape.They are highly weather-resistant and durable enough to be used outdoors for a long time.
