Description

[Detailed explanation of the idea] The present invention relates to a masking jig for painting.

Conventionally, when painting a motorcycle's fuel tank in two colors, the first color of paint was first sprayed onto the entire surface of the fuel tank suspended from a hanger, and after drying, there was no need to paint the second color. The second color is applied by covering the areas with a masking jig, and the masking jig is removed and then allowed to dry. By the way, the masking jig used in the conventional painting process is made of fiber-reinforced plastic, and when it is fitted into the fuel tank, it maintains the fitted state by its own elastic force. However, fiber-reinforced plastics do not have sufficient elasticity, and as they are repeatedly used, their elasticity becomes weaker. For this reason, when the masking jig is fitted to the fuel tank and painting is performed, the mounting position of the masking jig may shift, and in severe cases, the masking jig may fall from the fuel tank.

The present invention has been made in order to eliminate such conventional drawbacks, and an object of the present invention is to provide a masking jig for painting that can reliably maintain the fitting state to the object to be coated.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. First, in FIG. 1, when painting an object to be painted, for example, a fuel tank 1 of a motorcycle, in two colors, the entire surface of the fuel tank 1 is painted with the first color. After drying, the parts not to be painted with the second color are masked using the masking jig 2 according to the present invention, and the second color is painted.

In FIG. 2, a masking jig 2 includes a pair of handles 5 and 6 integrally provided on a masking body 4 which includes an elastic member 3 made of metal, for example, piano wire. The masking body 4 is made of synthetic resin, for example, fiber reinforced plastic (FRP), and has a shape of approximately U corresponding to the external shape of the attachment part of the fuel tank 1.
Formed in a letter shape. The elastic member 3 buried in the masking body 4 is curved into a substantially U-shape corresponding to the masking body 4, and is integrally buried inside the masking body 4 when the masking body 4 is molded. That is, the masking body 4 is molded in at least two layers, and after the first layer is molded, the elastic member 3 is temporarily fixed with adhesive paper 7, and then the second layer is stacked to form the inside of the masking body 4. The elastic member 3 is embedded in the.

Further, metal handles 5,
6 are welded in advance, and these handles 5 and 6 are projected from the surface of the masking body 4 when the second layer of the masking body 4 is molded. Therefore, the handles 5 and 6 are integral with the elastic member 3 within the masking body 4, and are firmly fixed to the masking body 4.

Next, to explain the operation of this embodiment, when painting the fuel tank 1 in two colors, first, the fuel tank 1 is suspended from a hanger (not shown).
After spraying and painting the entire outer surface of the fuel tank 1 with the first color paint, it is dried.

Next, apply the second color, but at this time,
As shown in FIG. 3, a masking tape 8 is pasted on the painted position of the fuel tank 1, and the masking jig 2 is fitted to the fuel tank 1 so as to overlap the masking tape 8. Thereafter, a second color is applied to the portions not masked by the masking jig 2, the masking jig 2 is removed, the masking tape 8 is peeled off, and the fuel tank 1 is dried to complete the coating process.

At the time of such painting, the masking jig 2 has an elastic member 3 embedded in its masking body 4, so its elastic force is strengthened, and it firmly clamps the fuel tank 1 and maintains its fitted state. securely hold. Therefore, as shown by the chain line in FIG. 3, the masking jig fixing tape 9 that has been used in the past can be placed in close contact with the surface of the masking jig 8, and the masking jig fixing tape 8 can be kept in close contact with the surface of the masking jig 8. This will definitely prevent it from falling.
In addition, the handles 5 and 6 that are held when attaching and removing the masking jig 2 to and from the fuel tank 1 are welded to the elastic member 3, so they do not fall off the masking body 4, extending the service life. Ru.

FIG. 4 shows another example of how the masking jig 2 is fitted to the fuel tank 1, in which the masking jig 2 is directly fitted to the fuel tank 1, and the edge of the masking jig 2 is Masking tape 8 may be attached to the fuel tank 1 and the fuel tank 1.

In the above embodiment, the motorcycle fuel tank 1
Although the masking jig for two-color painting has been described, the present invention is not limited thereto, and can be widely implemented as a masking jig for painting.

As described above, according to the present invention, in order to exert an elastic force in the direction of pinching the object to be painted when it is fitted to the object to be painted, it is formed of synthetic resin in accordance with the external shape of the object to be painted. Since a metal elastic member that exerts an elastic force in the same direction as the main body is embedded in the masking body, the elastic force of the synthetic resin is reinforced by the elastic member, and the force to clamp the object to be coated is improved. ,
The state of fitting to the object to be coated is reliably maintained. Therefore, during painting, the masking jig is reliably prevented from shifting from the dividing position or falling from the object to be painted, making it possible to obtain clear dividing lines, and eliminating the need for the masking jig that was previously required. Fixing tape is no longer required, improving work efficiency.
