Description

  The present invention relates to a corner masking piece set used for coating a surface to be coated with a masking tape so that the paint does not adhere to the surface to be coated.

  For example, when painting a door or window frame, conventionally, a winding tape and sheet called a masking tape or a curing tape is used to protect the window glass or window frame by performing a setup called curing. We are painting the outer walls. When masking tape is applied, work in the horizontal and vertical directions is easy and good adhesion can be obtained, but it is often the case that the tape is folded at the corner and work is not possible. was there.

  Referring to FIG. 3, 11 indicates a vertical portion of the window frame 10, 12 indicates a horizontal portion, 13 indicates a corner portion, and 14 indicates a masking tape. When the operator applies the masking tape 14 from the vertical portion 11 to the horizontal portion 12, the folding line 15 is set in the diagonal direction of the corner portion 13 (FIG. 3B), and the masking tape 14 is once bent 90 degrees outward from the frame ( 3C), and thereafter, an operation (FIG. 3D) is generally performed (FIG. 3D) in which the folding line 16 folds in the direction of the horizontal portion 12 (17 indicates an adhesive surface).

  When the tape attachment state at the corner portion 13 in this folding operation is seen, as shown in the sectional view in FIG. 3D, the adhesive surfaces 17 of the masking tape 14 are between the first fold line 15 and the next fold line 16. Bonds but does not bond to corner portion 13. Moreover, when the adhesion state in the horizontal part 12 is seen, although the part ahead of the fold line 15 adhere | attaches, only the half of the corner part 13 is adhere | attached, and the other half triangle of the corner part 13 is adhered. The region 18 floats and the adhesion is insufficient.

  In addition, there are workers with skills that cannot completely perform the folding operation itself, and as a result of the incomplete folding operation by such an operator, irregular folding may be performed, and wrinkles may be formed in the folded portion. For this reason, when effective masking cannot be performed, not only a clean painting line at the corner cannot be obtained, but also extra work such as removal of the coating sagging after painting work is required.

  On the other hand, when the prior art was investigated, Special Table 2010-513688 was found. The invention of the same issue is a masking article itself and is used to shield both the door hinge and the corner. This masking article has a form adapted to the shape of the door hinge, and facilitates handling when the masking article is applied, and is a corner part formed by crossing two masking tapes. It does not give any suggestions to the processing.

Special table 2010-513688

  The present invention has been made in view of the above points, and the problem is that masking of the corner portion formed by the intersection of two strips of masking tape can be suitably performed, and a clear parting line and a clean painted surface can be obtained. Is to be obtained. Another object of the present invention is to obtain a high-quality paint finish at the corner portion, even if it is not a skilled worker, and to reduce labor and greatly shorten the work period.

  In order to solve the above-mentioned problems, the present invention is used for coating the surface to be coated with a masking tape so that the paint does not adhere to the surface to be coated. A masking piece that has approximately the same size and shape as the shape of the corner portion formed by crossing, and an adhesive means is formed on the back surface, and the painter folds it into pockets for work clothes A means of having a size and shape that can be used without being stored and having a peeling surface on one side thereof for attaching the masking pieces in a plurality of rows and a plurality of rows so as to be peelable. It was taken.

  The present invention provides a corner masking piece comprising a masking piece having substantially the same size and shape as the shape of the corner portion, and an adhesive means formed on the back surface, and a mount on which a plurality of masking pieces are attached. Is a set. The purpose is to prevent a shortage of adhesion and the occurrence of folding wrinkles that occur when a tape is folded to work by sticking a masking piece to the corner portion.

  Each masking piece has almost the same size and shape as the shape of the corner formed by crossing two masking tapes from two directions. It has a size and a shape that can be used without being folded in pockets of work clothes. And the said masking piece is affixed on the peeling surface, and it arranges in multiple rows and multiple rows.

  As a masking piece set for corners according to the present invention, one masking piece is a square having a size of 33 × 33 mm, and one mount has a width of at least two rows so that the masking pieces are pasted in at least two rows. What is set as a rectangle having a size of 100 mm or less and a length of about 150 mm or less is one desirable form.

  Since the present invention is configured and operates as described above, a masking piece is attached to a corner portion formed by the intersection of two strips of masking tape, and the paint is applied to the surface to be coated by the masking tape. It can be coated so that it does not adhere, and effective masking can be performed, and there is an effect that a clear parting line and a beautiful painted surface can be obtained. Further, according to the present invention, even if it is not a skilled worker, it is possible to obtain a high-quality paint finish at the corner portion, and also it is possible to reduce labor and greatly shorten the work period.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of a corner masking piece set 20 according to the present invention. In the description of the embodiment, the same components as those in FIG.

  The masking piece set 20 has almost the same size and shape as the shape of the corner portion 13 formed by crossing two strips of masking tapes 14 from two directions, and an adhesive means 23 is formed on the back surface. The masking piece 21 and the size and shape of the masking piece 21 that can be used during the work by being stored in the pockets of the work clothes without being folded, and the masking pieces 21 are peeled in a plurality of rows and a plurality of rows. It is composed of a mount 22 having a peeling surface 24 on one side thereof for possible attachment.

  The masking piece 21 is made of a paper product. For example, one masking piece 21 is formed in a square having a size of 33 × 33 mm. The dimension of 33 mm is an example, and the present invention should not be limitedly used. However, it is a dimension that is easily compatible with the width of commercially available masking tapes, the width of the window frame 10 to which the masking tape is attached, and the like, and it can be said that it has a certain degree of rationality as a numerical value.

The masking piece 21 in the embodiment is made of a thin film made of Japanese paper, and is formed by forming an acrylic pressure-sensitive adhesive layer as the bonding means 23, and is a commercially available product called sealing masking tape G-91Re (trade name). . The physical property table is shown below.
Table 1

  The above physical properties are examples, and are not limited to these values. However, the main component Japanese paper is a material that is biodegradable and does not contain harmful components, is easy to peel off from the mount 22, does not curl when picked with a fingertip, maintains flatness, and has good workability. . In addition, the name by the thickness of a thin piece follows the customary thing which calls a thing thicker than 1/100 inch (about 0.25 mm) a sheet | seat, and a thin thing a film.

  In the embodiment, the mount 22 is made of a sheet material thicker than the masking piece 21, and the peeling surface 24 is formed on the entire surface. The masking pieces 21 of the above size are affixed to the peeling surface 24 in an arrangement of two rows and three rows. In such an example, the mount 22 has an appropriate size of a rectangle having a width of about 80 mm and a length of about 140 mm. The size of the breast pocket of men's clothing is generally 90-100 mm wide and 100-120 mm deep, so the masking piece set 20 of 80 × 140 mm can fit in the pocket with room. It is.

  A method of using the masking piece set 20 having such a configuration will be described with reference to FIG. FIG. 2A shows the corner portion 13 of the window frame 10 as in FIG. 1. First, the masking piece 21 of the present invention is attached thereto. Since the masking piece 21 is simply peeled off and pasted from the mount 22, this operation can be performed by anyone who is not an expert. FIG. 2B shows a state after the work. Even if the masking piece 21 is attached to the corner portion 13 with a slight deviation, there is almost no problem in the painting process.

  Next, the masking tape 14 is attached to the vertical portion 11 of the window frame 10. At this time, the masking piece 21 may be covered with the masking tape 14 (FIG. 2C). Thereafter, the masking tape 14 is affixed to the horizontal portion 12, and the masking piece 21 is similarly covered at this time (this state is shown in FIG. 2D). In the above description, the masking piece 21 is attached to the corner portion 13, the masking tape 14 is attached to the vertical portion 11, and then temporarily separated and then attached to the horizontal portion 12.

  However, it is obvious that the masking tape 14 for corners according to the present invention may be used and the masking tape 14 may be folded in the same manner as the previous work procedure shown in FIG. Since the corner portion 13 of the window frame 10 is completely covered by using the masking piece 21, the corner portion 13 is completely masked even if the same method as before is performed. It does not cause problems such as.

  According to the present invention, the masking operation can be easily executed as described above, and the problem of inability to do so hardly occurs. Further, even if the position is slightly shifted when the masking piece 21 is pasted, the painting operation is not affected. Therefore, work efficiency can be remarkably improved. After the masking operation, the necessary curing is performed and the painting operation is carried out.

An example of the masking piece set for corners which concerns on this invention is shown, A is a front view and B is a side view. It is front explanatory drawing which shows the usage method of the masking piece for corners same as the above in order of the process of ABCD. It is front explanatory drawing which shows the usage method of the masking piece for corners so far in order of the process of ABCD.
