Description

[Detailed explanation of the invention] (1) Field of industrial application The present invention relates to a masking material for front fork claws or back fork setters in bicycle frame painting, and more specifically, for masking materials for front fork claws or back fork setters in the U-shape of front fork claws or back fork setters. A fixed stopper part that can be fitted into the groove by using a groove, and a pair of left and right oppositely provided on both left and right sides of the fixed stopper with an interval substantially equal to the thickness of the front hawk claw or back hawk setter. To make it possible to simply and accurately mask a front fork claw or a back fork setter when painting a bicycle frame, thereby streamlining the bicycle frame painting.

(2) Prior Art When painting a bicycle frame, it is necessary to mask the front fork claw or back fork setter of the frame.

However, because the above-mentioned front hawk claw or back hawk setter has a complicated shape with a U-shaped groove in the center, conventionally there was no suitable masking material, and most of them were wrapped in adhesive tape or the like. Masking was done by cutting pieces into appropriate shapes and pasting them together.

(3) Problems to be solved by the invention However, this conventional method using adhesive tape has the following problems.

First, depending on how the tape is adhered, a gap is likely to form between the tape and the unpainted portion of the bicycle frame, and as a result of paint flowing into the gap, a reliable masking effect cannot be obtained.

Second, applying tape during masking requires precision, but it takes a certain amount of time and skill to accurately position and apply the tape to a predetermined position. Efficiency is low.

Third, the tape to be pasted must be cut to match the shape of the masking part each time, and the cutting must be made to match the shape of the masking part accurately, which is a difficult and expensive process. They are forced to do such complicated work.

Fourthly, it is difficult to remove the tape after painting because it is covered with paint.

Fifth, because adhesive tape cannot be reused, the cost of masking material consumption is high.

(4) Means for solving the problems The purpose of this invention is to solve the above-mentioned drawbacks, and it can be installed with one touch when masking and painting a part of the bicycle frame. Accurate and reliable masking effects can be obtained without creating gaps, and the masking material can be applied and removed easily without requiring any skill. It is an object of the present invention to provide a simple masking material for painting a bicycle frame, which has a concave portion on its outer surface so that it can be easily attached and detached, and can be reused repeatedly.

The specific content of the present invention will be explained below according to an embodiment shown in the drawings. FIG. 1 shows a masking material suitable for masking the backhawk setter 7 of a bicycle frame, and FIG. The masking materials suitable for masking the front hawk claw 10 are shown, respectively.
0 or U-shaped groove 1 of Buckhawk setter 7
a fixed stopper part 1 that can be fitted into the fixed stopper parts 1 and 8; and rubber parts provided opposite to each other on both left and right sides of the fixed stopper part 1 with an interval substantially equal to the thickness of the front fork claw 10 or the back hawk setter 7. Or members 2a and 2b made of elastic material such as soft synthetic resin.
It consists of

Furthermore, the members 2a and 2b have grooves 4a and 4b, leaving their peripheral edges 3a and 3b on the inside facing each other.
are formed, and recesses 5a and 5b are formed in the center of the outer surface.

Furthermore, the fixed stopper part 1 retains the elastic force of the members 2a and 2b disposed opposite to each other on both its left and right sides, and also maintains the shape and size of the U-shaped grooves 11 and 8 provided in the front fork pawl 10 or the back fork setter 7. When the fixed stopper part 1 is fitted into the U-shaped grooves 11 and 8, the members 2a and 2b on both sides have the inner peripheral edges 3a and 3b aligned with the front hawk claws. 10 or the side of the backhawk setter 7 to completely mask the area surrounded by the peripheral edges 3a and 3b.

(5) Effect In the above-mentioned structure, before painting, as shown in Fig. 3 and below, it is attached to the setter 7 of the backhawk 6 on the bicycle frame from the opening of the U-shaped groove 8 toward the back as shown in Fig. 1. By inserting the fixed stopper part 1 made of masking material until its tip reaches the end, the members 2a and 2b on both sides of the fixed stopper part 1 are removed from the inner peripheral edges 3a and 3.
b is brought into close contact with the side surface of the backhawk setter 7 to completely mask the area surrounded by the peripheral edges 3a and 3b.

Further, by inserting the fixed stopper part 1 made of masking material shown in FIG. The inner peripheral edges 3a, 3b of the members 2a, 2b on both sides are brought into close contact with the side surfaces of the front fork claw 10, so that the portion surrounded by the peripheral edges 3a, 3b can be completely masked.

(6) Effects of the invention As explained above, the masking material of the invention is molded using elastic rubber or the like as its material, and the squeezing force due to its elasticity is concentrated only on the inner peripheral edge. This makes it possible to further strengthen the airtightness, which reliably prevents paint from flowing into the space between the masking material and the area to be painted, thereby achieving a complete masking effect. By preparing the material in a manner that matches the shape of the part, it is possible to achieve operational effects such as eliminating the need to cut a masking member such as a tape to fit the shape of the part when masking, as was done in the past. In addition, due to the presence of the fixed stopper part, accurate positioning can be achieved by simply inserting it into the U-shaped groove of the front fork claw or back fork setter until it touches the U-shaped groove.As a result, the overall painting work on the bicycle frame can be done quickly. Productivity can be improved.

Furthermore, the recesses 5a and 5b provided on the outer surface not only make it easier to attach the masking material, but also make it easier to remove the masking material, especially when removing the masking material after painting the frame, despite the paint adhering to it. can.
