[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a masking material used for covering and protecting a predetermined surface of an article.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, for example, when coating an automobile, a masking material (2) made of a flexible material such as polypropylene is coated so that the bumper (1) is not coated. Wear it. When the masking material (2) is applied to the bumper (1), if the masking material (2) is deformed, it becomes difficult to remove and attach the masking material (2).
(2) hardly adheres to the masking portion, so that the masking material (2) has a horizontal rib (3) and two upper and lower sides of the horizontal rib (3).
A plurality of vertical ribs (4, 5) are arranged in rows to prevent deformation.

[0003]

[Problems to be solved by the invention] However, in the above-mentioned conventional masking material (2), the vertical ribs above and below the horizontal rib (3) are used.
Since (4,5) communicate with each other, the apparent length L of the vertical rib is
The sum of the length of (4) and the length of the vertical rib (5) resulted in a large moment applied to the vertical rib, and the effect of the vertical rib to prevent deformation was small.

[0004]

According to the present invention, as a means for solving the above-mentioned conventional problems, a masking material (2) attached to a predetermined surface of an article to protect clothing on the predetermined surface is provided.
A), the masking material (2A) has a plurality of stages (21A, 22A)
A plurality of vertical ribs (4A, 5A) are arranged in a row, and the adjacent steps (21A, 2A)
The longitudinal ribs (4A, 5A) of 2A) provide a staggered masking material.

[0005]

[Function] In the present invention, the masking material (2A) is provided with a plurality of vertical ribs (4A, 5A) in a plurality of steps, and the vertical ribs (4A, 5A) of the adjacent steps (21A, 22A) are not connected to each other. Since the apparent length of the vertical rib is equal to the actual length of the vertical rib (4A) and the vertical rib (5A), and the moment exerted on the vertical rib (4A, 5A) becomes smaller, The deformation preventing effect by the vertical ribs (4A, 5A) is increased.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. (2A) is a masking material to be applied to a bumper (1) of an automobile, which is suitable for the bumper (1). A transverse rib (3A) having a shape to fit, along the longitudinal direction, the transverse rib (3A)
Vertical ribs (4A, 5A) are provided in the upper and lower two stages. The vertical ribs (4A) in the upper row (21A) and the vertical ribs (5A) in the lower row (22A) are alternated.

Further, flanges (6A, 7A) having a U-shaped cross section are formed on the upper and lower edges of the masking material (2A), and a longitudinally central portion of the lower stage (22A) of the masking material (2A). Is formed with a raised portion (8A), and an inclined portion (31A, 31A, 71A, 7A) is formed between the lateral rib (3A) and the flange (7A) on the left and right sides of the raised portion (8A).
1A) are formed respectively.

In the masking material (2A), a horizontal rib
(3A) and the flanges (6A, 7A) prevent bending deformation in the longitudinal direction, and the upper and lower vertical ribs (4A, 5A) prevent bending deformation in the short direction. A ridge (8A) at the center in the longitudinal direction of the lower stage (22A) of the material (2A)
Are formed, and inclined portions (31A, 31A, 71A, 71A) on the lateral ribs (3A) and the flange (7A) on the left and right sides of the raised portion (8A).
Are formed, the masking material (2A) exhibits even greater resistance to bending deformation in the hand direction, and when attached to the bumper (1) as shown in FIG. Disappears.

In addition, two vertical ribs on the upper and lower sides of the masking material (2A)
(4A, 5A) are not communicated and are staggered, so that the actual length and the apparent length are substantially equal, and the moment exerted on the longitudinal ribs (4A, 5A) is reduced accordingly.

In this embodiment, the horizontal ribs (3A) are provided. However, when the upper and lower vertical ribs (4A, 5A) are communicated with each other, when the masking material (2A) is manufactured by vacuum forming, the vertical ribs are formed. (4A, 5
A wrinkle is formed in the horizontal rib (3A) at the communicating portion of (A), and it becomes a structural defect, and it becomes easy to bend at that portion.However, in this embodiment, the upper and lower vertical ribs (4A, 5A) are staggered. Such a structural defect is not formed in the lateral rib (3A).

The masking material (2A) of the present invention is a sheet of a thermoplastic plastic such as polystyrene, polyethylene, polypropylene, ethylene-propylene copolymer, polyvinyl chloride, vinylidene chloride copolymer and ethylene-vinyl acetate copolymer. Or a sheet of the thermoplastic foam, or a sheet of a thermosetting plastic such as polyurethane, melamine resin, urea resin, phenol resin, epoxy resin, or a sheet of the foam of the thermosetting plastic, or styrene butadiene rubber A sheet of synthetic rubber and natural rubber such as acrylonitrile-styrene-butadiene rubber, acrylonitrile-butadiene rubber, or a sheet of a foam of the rubber, or a mixture of polyamide fiber, polyester fiber, acrylic fiber, acetate fiber, etc. Synthetic fiber, wood fiber, natural fiber, inorganic fiber and their non-woven fabric and knitted fabric, paper, cardboard,
It is a molded article formed of an impregnated sheet obtained by impregnating a binder such as polyurethane, melamine resin, urea resin, and phenol resin into wood, plywood, or a hard board, or a metal sheet, or a laminate of two or more of the above materials.

The masking material of the present invention includes calcium carbonate, magnesium carbonate, barium sulfate, calcium sulfate, calcium sulfite, calcium phosphate, calcium hydroxide, magnesium hydroxide, aluminum hydroxide, magnesium oxide, titanium oxide, iron oxide, Zinc oxide, alumina, silica, diatomaceous earth, dolomite, gypsum, talc, clay, asbestos, mica, glass fiber, calcium silicate, benite, white carbon, carbon black, iron powder, aluminum powder, stone powder, blast furnace slag, fry One or more of inorganic fillers such as asi, fillers such as wood flour, coconut powder, walnut powder, starch, cotton fiber powder, flour, coloring agents such as dyes and pigments, and plasticizers such as DOP and DBP. May be mixed.

[0013]

[Effects of the Invention] Therefore, in the present invention, since the masking material is hardly deformed when it is mounted and removed, the work of mounting and removing the masking material is facilitated, and the masking material can be closely attached to the masking portion. .
