Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a masking material capable of completely masking the entire masked member.

[0002]

[Prior art]

 For example, when painting the window frame of an automobile door and the part below it in different colors, first paint the window frame, then mask the window frame with a masking material, and then paint the window frame below the window frame. It is common to paint.

In this case, an adhesive tape or an aluminum foil tape was used as a masking material for the window frame portion, and these tapes were wound around the window frame portion before painting before painting.

However, according to this method, not only is it troublesome to wind or peel off the tape, but also it is necessary to heat and dry the tape after painting. This heating causes the tape to stick to the window frame portion. In some cases, peeling was difficult, and there was also a trouble that the peeled end of the tape could not be easily found.

For this reason, as shown in, for example, Japanese Utility Model Registration No. 2503100 or 2532839, a masking material is made of a synthetic resin to form a molded product having a substantially U-shaped cross section, which is then molded. A method has been developed that uses the elasticity of the product itself to fit it into a window frame, which is the material to be masked, for masking.

[0006]

[Problems to be solved by the invention]

 However, since the masking material disclosed in the above publication has a substantially U-shaped cross section, an open surface is necessarily generated even when the masking material is fitted to the window frame member. Although it is often blown into the window frame portion from the open surface, and the masking material has flanges formed integrally with the masking material main body on both sides of the open surface for the purpose of preventing this blowing, In reality, it was impossible to prevent paint from being blown.

[0007] Although the conventional masking material can be fitted to the window frame portion by utilizing its elasticity, it does not fall off during painting.

In other words, in order to completely prevent the above-described spraying of the paint and the falling off of the masking material, it is necessary to cover the entire outer periphery of the masked member. Injection molding, vacuum molding, or air pressure molding cannot be performed because demolding becomes impossible, and the above-mentioned problem arises when tape is used as described above, so that tape cannot be used after all.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the masking material according to the present invention is based on a modified columnar member having a polygonal cross section partially having a concave groove, a ridge, and a flat surface along the longitudinal direction. A synthetic resin sheet having an inner peripheral shape corresponding to the outer peripheral shape of the masked member, covering the outer periphery of the masked member, and both end pieces abutting or overlapping each other on the flat surface. After the masking material main body and both end pieces of the masking material main body are abutted or overlapped with each other, they are constituted by fixing means for connecting and fixing the both end pieces to each other from the outer surface thereof.

In order to solve the above-mentioned problem, a masking material according to the present invention is characterized in that a cross section partially having a concave groove, a ridge, and a flat surface along a longitudinal direction has a polygonal shape. A synthetic resin material having an inner peripheral shape corresponding to the outer peripheral shape of the masked member formed of a columnar body, covering the outer periphery of the masked member, and both end pieces abutting or overlapping each other in the concave groove; After inserting both ends of the masking material body into the groove of the masking member by abutting or overlapping with the masking material body made of a sheet, the elastic fixing member can be fitted into the groove from the outer surface thereof. It is composed of members.

Further, in order to solve the above-mentioned problem, a masking material according to the present invention is characterized in that a cross section partially having a concave groove, a ridge, and a flat surface along a longitudinal direction has a polygonal shape. It has an inner peripheral shape corresponding to the outer peripheral shape of the masked member composed of a columnar body, covers the outer periphery of the masked member, and bends outward from the flat surface or the groove corresponding position at both ends. A masking material body made of a formed synthetic resin sheet and a fixing means such as a Velcro fastener or an adhesive tape for connecting and fixing the both end pieces to each other after facing the surfaces of both end pieces of the masking material body. It was done.

[Embodiment of the invention]

 Next, an embodiment of the masking material according to the present invention will be described with reference to the drawings. Reference numeral 1 denotes a masked member partially having a concave groove 2, a ridge and a flat surface 3 along the longitudinal direction. The masking member is a window frame portion of a passenger car.

The window frame portion of the passenger car has an irregularly shaped columnar body having a polygonal surface as shown in the figure, and the concave groove 2 is for fitting a weather strip for sealing the window glass. The masked member 1 shown here is an example of an existing type of passenger car. Therefore, although there is a slight difference depending on the vehicle type, the masked member 1 is common in that it has a deformed columnar body having a polygonal surface as described above. doing. However, the masked member 1 in the present invention is not limited to the window frame portion of a passenger car, but can be widely used for those having the concave groove 2 and the flat surface 3 as described above.

Reference numeral 4 denotes a masking material main body having an inner peripheral shape that substantially matches the outer peripheral shape of the masked member 1, and is formed in a shape that can cover the entire periphery of the masked member 1. At the same time, when the masking material main body 4 is fitted to the masked member 1, the masking material body 4 comes into close contact or almost close contact (in the drawing, a gap is shown between the masking material body 4 and the masked member 1 so as to be present. However, this is for the convenience of illustration, and in reality, it is in close contact or almost in close contact.)

Reference numeral 5 denotes an end piece of the masking material main body 4, which may be formed more flexibly than the masking material main body 4. That is, the end pieces 5 are fixed to the masking member 1 by an elastic fixing member 6 or other fixing means 7 described later. The elastic fixing member 6 is inserted into the concave groove 2 from outside the both end pieces 5 after being inserted so as to overlap with the concave groove 2 formed in the masking member 1. Both end pieces 5 are preferably formed more flexibly than the masking material main body 4.

On the other hand, as will be described later, even if both end pieces 5 are similarly inserted into the concave grooves 2, they may be inserted so as to abut each other and may be abutted or overlapped on the flat surface 3 of the masked member 1. After that, when these are connected and fixed by the fixing means 7, the both end pieces 5 may have the same hardness (or softness) as the masking material main body 4.

However, the masking material main body 4 is not formed to be extremely hard. That is, the masking material main body 4 and the end piece 4 are integrally formed of a synthetic resin, and the masking material main body 4 opens the end piece 4 to both sides by human power, but retains flexibility and so as not to break. It is formed to have shape. That is, in order to form the masking material main body 4 as described above, the masking material main body 4 can also be realized by changing the thickness of the corner ridge portion and the flat surface portion. In this case, the thinner thickness is, for example, 0.7 to 2.0 mm, and the thicker thickness is, for example, 3 to 2.0 mm. It is formed to a thickness of about 0 to 6.0 mm. By forming in this way, not only the flexibility and the shape retention can be realized, but also the handling ease when attaching or detaching the masking material main body 4 to or from the masking member 1 is improved. is there. In addition, as for the thickness when the both end pieces 5 of the masking material body 4 are formed flexibly, the thinner one of the above numerical values may be selected.

The masking material main body 4 can be molded by a molding method based on vacuum molding, air pressure molding, and press molding, which is combined with blow molding. Molding machines that can do this with one device have already been developed.

Examples of the synthetic resin material used here include thermoplastic resins such as nylon, polyester, polystyrene, polyethylene, polypropylene, and polyvinyl chloride, or a resin mixture thereof, and a resin for improving heat resistance. Mixing inorganic fillers such as calcium carbonate, talc, bentonite, stone powder, blast furnace slag and fly ash is conventional.

The elastic fixing member 6 is formed by fitting the masking material body 4 to the masked member 1 and then fitting the elastic fixing member 6 into the concave groove 2 so that the masking material body 4 and the masking member 1 Is used to firmly adhere the masking material. For this purpose, it is necessary to prevent the masking material main body 4 from being accidentally moved in this state, to facilitate the attachment / detachment work, and to enable repeated use. Needless to say, high heat resistance and high elasticity are required, so a spring material formed by bending a metal plate into a U-shape, V-shape, or coil strip, or fluoro rubber, silicon rubber, butyl rubber, a It is preferably formed of cryl rubber or the like, and the width thereof is formed to be slightly larger than the width of the concave groove 2 or more. Regarding the length of the elastic fixing member 6, a plurality of short ones may be prepared and used in a connected manner, but may be arranged in a required place in a stepping stone shape.

Then, the masked member 1 is fitted so as to be covered with the masking material main body 4. In this case, the masking material main body 4 can be pulled open by pulling the both end pieces 4 right and left. In addition, the masking member 1 is formed so that the inner circumferential shape of the masking material main body 4 matches the outer circumferential shape of the masked member 1.

According to the invention described in the first aspect, both end pieces 5 of the masking material main body 4 are abutted or overlapped with each other on the flat surface 3 of the masked member 1, and a fixing means such as an adhesive tape is used. 7, and are connected and fixed to each other.

According to the invention described in claim 2, both end pieces 5 of the masking material main body 4 are inserted into the concave groove 2 of the masked member 1 so as to abut against each other or overlap with each other. The elastic fixing member 6 is fitted into the groove 2 from the outside of the groove 4 (the groove 2). The masking material main body 4 can be fixed to the masked member 1 by inserting the elastic fixing member 6. However, if there is a concern that the masking material main body 4 may come off, the masking may be performed from outside the elastic fixing member 6 with an adhesive tape or the like. The material body 4 and the masked member 1 may be integrally wound (partially) and fixed.

Further, in the present invention described in claim 3, both end pieces 5 of the masking material main body 4 face each other in the concave groove 2 or the flat surface 3 of the masked member 1, and are arranged on the both end pieces 5 in advance. It is connected and fixed to each other by the provided Velcro fastener 8. In this case, an adhesive tape or a clip can be used instead of the Velcro fastener 8.

When removing the masking material main body 4 from the masked member 1, the reverse operation may be performed.

[Effect of the invention]

 As described above, according to the masking material according to the present invention (claim 1), the masking is made of a deformed columnar body having a polygonal cross section partially having a concave groove, a ridge, and a flat surface along the longitudinal direction. A masking material body made of a synthetic resin sheet having an inner peripheral shape corresponding to the outer peripheral shape of the member, covering the outer periphery of the masked member, and having both end pieces abutting or overlapping each other on the flat surface; After the two end pieces of the masking material main body are abutted or overlapped with each other, they are constituted by fixing means for connecting and fixing these two end pieces together from the outer surface, so that the entire masking member is covered with the masking material main body. After fitting, both ends of this masking material body are abutted or overlapped on the flat surface formed on the masked member. Then, if the both end pieces are connected and fixed to each other from outside by a fixing means, the entire periphery of the masked member can be covered by the masking material main body. Adhesion of the masking material and the falling off of the masking material from the masking member can be completely prevented, and the masking material body is almost in close contact with the masking member. Not only can masking be performed, but also the masking material body can be easily attached and detached to and from the masked member by a small number of people (conventionally, a group of four persons, but according to the present invention, one to two persons). It has the effect of being able to do so.

Further, according to the masking material of the present invention (claim 2), the cover is formed of a deformed columnar body having a polygonal cross section partially having a concave groove, a ridge, and a flat surface along the longitudinal direction. It is made of a synthetic resin sheet that has an inner peripheral shape corresponding to the outer peripheral shape of the masking member, covers the outer periphery of the masked member, and has both ends abutting or overlapping each other in the concave groove. After the masking material main body and both ends of the masking material main body are inserted into the concave groove of the masked member so as to abut or overlap with each other, the elastic fixing member can be fitted into the concave groove from the outer surface thereof. Therefore, after the masking material body is fitted so as to cover the entire masked member, both end pieces of the masking material body are formed on the masked member. Inserting the elastic fixing member into the concave groove from the outside so as to abut or overlap in the concave groove to cover the entire masked member, similar to the invention according to claim 1 above. It has the effect of.

Further, according to the masking material according to the present invention (claim 3), a masking target is formed of a deformed columnar body having a polygonal cross section partially having a concave groove, a ridge, and a flat surface along the longitudinal direction. A synthetic resin material having an inner peripheral shape corresponding to the outer peripheral shape of the member, covering the outer periphery of the masked member, and forming both end pieces bent outward from the flat surface or the position corresponding to the concave groove. After the masking material main body made of a sheet and the surfaces of both end pieces of the masking material main body face each other, fixing means such as a Velcro fastener or an adhesive tape for connecting and fixing the both end pieces to each other are used. It has a similar effect.
