Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening masking material for protecting paints from entering holes such as a harness hole and a water drain hole provided in a floor panel when painting an under floor of an automobile.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, for example, in order to protect the opening (2) of a car floor panel (1) from being painted, it is made of plastic with a flange (5) at the opening edge of the container-like insert (4). The masking material (3) is provided (No. Shokai 61-130368).

[0003]

[Problems to be solved by the device]

 However, the conventional masking material (3) cannot be tightly attached to the opening (2), and there is a risk that it may come off from the opening (2) before or during painting.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention raises the substantially central part of the bottom of the container-like insertion part (14) having a shape corresponding to the shape of the opening (2) over the entire diameter. To form a clip portion (16), and an engaging protrusion (17) that engages with the back side peripheral edge of the opening portion (2) is provided on the peripheral surface of the insertion portion (14). Is provided.

[0005]

[Action]

 When the clip portion (16) of the masking material (13) of the present invention is pinched with a finger and pushed, the masking material (13) bends around the clip portion (16). In this state, if the insertion part (14) of the masking material (13) is inserted into the target opening (2) and the finger is released, the masking material (13) will be stretched by elasticity and the insertion part (14 The engaging projection (17) of (1) engages with the back side peripheral edge of the opening (2).

[0006]

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 to 4. A masking material (13) is a container-shaped insertion part (14) and a flange (15) inserted from an opening edge of the insertion part (14). ) And a clip portion (16) formed by raising a substantially central portion of the bottom portion of the insertion portion (14) over the entire diameter, and the clip portion is provided on the peripheral surface of the insertion portion (14). An engaging protrusion (17) is formed to guide the (16).

The masking material (13) is a sheet of thermoplastic such as polystyrene, polyethylene, polypropylene, ethylene-propylene copolymer, polyvinyl chloride, vinylidene chloride copolymer, ethylene-vinyl acetate copolymer, or the like. The thermoplastic plastic foam sheet, the thermosetting plastic sheet of polyurethane, melamine resin, urea resin, phenol resin, epoxy resin or the like, or the thermosetting plastic foam sheet, or styrene-butadiene rubber. , Sheets of synthetic rubber and natural rubber such as acrylonitrile-styrene-butadiene rubber, acrylonitrile-butadiene rubber or foams of the rubbers, or methylpentene copolymer, polyethylene terephthalate, polyamide, po Liquid crystal types such as carbonate, cellulose acetate, polysulfone, polyether sulfonate, polyphenylene sulfide, polyphenylene oxide, polyamide imide, polyether imide, polyether ether ketone, polyimide, engineering plastics, liquid crystal types such as polyallyl ether, etc. Sheets or foam sheets of one or a mixture of two or more engineering plastics such as compression molding type of raw resin, amorphous polymer, aminobiimaleimide, thermosetting aromatic polyimide of biimaleimidoazine, etc. Synthetic fibers such as liamide fiber, polyester fiber, acrylic fiber, acetate fiber, wood fiber, natural fiber, inorganic fiber and their non-woven fabrics, knitted fabrics, paper, cardboard, wood, plywood, ha It is an impregnated sheet obtained by impregnating a board or the like with a binder such as polyurethane, melamine resin, urea resin or phenol resin, or a metal sheet, or a molded product made of a laminate of two or more of the above materials. The masking material (13) of the present invention is particularly preferably one having a high internal elasticity of the above materials, and these elastic materials are manufactured by vacuum molding, injection molding, press molding, cast molding or the like.

The masking material (13) 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, bentonite, white carbon, carbon black, iron powder, aluminum powder, stone powder, blast furnace slag, Inorganic fillers such as fly ash, wood powder, coconut powder, walnut powder, starch, cotton fiber powder, wheat flour, and other fillers, dyes, pigments and other colorants, DOP, DBP and other plasticizers, etc. Two or more kinds may be mixed.

As shown in FIG. 3, the masking material (13) can be bent around the clip portion (16) by pinching and pushing the clip portion (16) with a finger. In this state, for example, an automobile floor panel When the insertion part (14) is inserted into the opening (2) of (1) and the finger is released, the masking material (13) stretches elastically to restore its shape as shown in FIG. The engaging protrusion (17) of 4) engages with the back side peripheral edge of the opening (2) to prevent the masking material (13) from coming off the opening (2).

In this way, the masking material (13) is attached to the opening (2) and then painting is performed. After the painting, the clip portion (16) of the masking material (13) is pinched with a finger and bent, The masking material (13) is removed from the opening (2).

[0011]

[Effect of device]

 Therefore, in the present invention, the masking material can be securely attached to the opening without separating.
