Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a masking device used primarily to apply color-coded coating to the outer surface of a motorcycle fuel tank or other curved object to be coated.

Conventionally, as this type of masking means, for example, the first
As shown in the figure and second figure, a parting tape c is pasted on the outer surface of the non-painted part b of the fuel tank or other object to be painted a along the upper edge thereof, and then it is rolled in advance. The prepared roll masker d made of paper or resin sheet is unrolled and applied one after another, and the upper edge of the roll masker d is slightly polymerized and adhered to the tape c, so that next time a new painted surface e is formed on the upper side of the roll masker d. A method is known in which the masker d and the tape c are removed after forming the masker d, but in such a method, since the masker d already exists on a flat surface, it is removed from the curved surface of the non-painted area b. It takes a considerable amount of time and effort to apply the masker d in a roughly conforming manner, and it is also wrinkled to some extent, creating gaps through which paint mist tends to enter. They cannot be used, and therefore, a new one must be used each time, which is uneconomical and other inconveniences.

The purpose of the present invention is to obtain a device free of such inconveniences, and is made from a synthetic resin thin plate formed into an inner surface shape that approximately conforms to the outer surface of the non-coated portion 2 of a fuel tank or other object to be coated 1. A coating film 4 is attached to at least one side edge of the masking member 3, spanning between the masking member 3 and the object 1 to be coated, to be formed next.
A guide portion 7 such as a guideline is formed to regulate the adhesion position of the parting tape 6 that forms the parting edge 5.

FIGS. 3 to 5 show one example, and the masking member 3 is made of a sheet material made of synthetic resin such as orientated polyester, acrylic butadiene styrene, or polyvinyl chloride, and is made of a sheet material made of a synthetic resin such as orientated polyester, acrylic butadiene styrene, or polyvinyl chloride. It is generally made by vacuum forming, and its wall thickness is, for example, 0.5
It should be about 3 mm. If necessary, a magnet 8 is buried along the inner surface of the member 3 as shown clearly in FIG. 5, so that the magnet 8 is attracted to the member 3 when it is attached to the non-coated portion 2 side. The guide portion 7 is, for example, in the shape of a concave groove formed along the upper edge of the member 3, as clearly shown in FIG. I made it so that a 5-sided edge was created. In the illustrated example, the object to be painted 1 is prepared in a state in which the first coating film 1a has been applied in advance, and the entire object is painted in two upper and lower colors using the coating film 4 described above. .

FIGS. 6 and 7 show a modification thereof. In this case, the above-mentioned guide portion 7 consists of a marking line or other indicating line made on the member 3, and the parting tape 6 is attached along this line. It is stuck and extends upward,
A separate stripe tape 6a is attached in advance to the upper inner surface of the tape 6 using the upper edge of the member 3 as a guide surface, and the tape 6a is then left as it is after painting to form a striped pattern. I decided to make it. In this case, the tape 6a cooperates with the tape 6 and effectively functions as a parting tape inside the tape 6. The remaining points are not particularly different from the previous one.

To explain its operation, the masking member 3 is brought into contact with the non-painted part 2 of the object 1 from the outside to position it, and then the parting tape 6 is guided along the upper edge by the guide part 7. The masking member 3 is fixed in a sealed state by pasting, and in this state, painting is applied to form a coating film 4. Next, the tape 6 is peeled off and the member 3 is removed. can be used as is for the next task. According to the inventor's experiments, the installation process takes 5 seconds to 5 minutes per unit, compared to the conventional 2 to 5 minutes.
10 seconds and the member 3 is repeatedly pressed for example 20 seconds.
It was confirmed that the member 3 could be used more than once, and that the member 3 was in close contact with the non-painted area 2 and sealed with the tape 6, so that there were no gaps and the intrusion of mist was 100% prevented.

In this way, according to the present invention, the masking member 3 is made of a synthetic resin thin plate molded to have an inner surface shape that approximately matches the outer surface of the non-painted portion 2, and a guide portion 7 for regulating the adhesion position of the parting tape 6 is attached to the masking member 3. This makes the attachment and detachment work simple and easy, and the member 3 can be used repeatedly, making it economical.Furthermore, it does not cause wrinkles or the like when applied, thus avoiding the various disadvantages of the conventional ones mentioned above. It has the advantage of being simple in structure and inexpensive.

Claims (1)

[Scope of utility model registration request] At least one side edge of a masking member 3 made of a thin synthetic resin plate formed into an inner surface shape that approximately conforms to the outer surface of the non-painted portion 2 of a fuel tank or other object to be painted 1 is provided between the masking member 3 and the object to be painted 1. This masking device for painting is formed with guidelines and other guide parts 7 for regulating the adhesion position of a parting tape 6 which is pasted over the area to form a parting edge 5 of a coating film 4 to be formed next.
