Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface decoration method for decorating the surface of an article, and more particularly to a coating alternative surface decoration method for performing surface decoration as an alternative to conventional coating. However, the term “decoration” in the present invention does not merely apply color to the surface of an article instead of painting, but includes photographs, paintings, reliefs (reliefs), small sculptures, patterns, characters, symbols, It also includes those that apply decorative patterns such as colors to the surface, or apply uneven three-dimensional patterns to the surface of the article. The present invention further relates to a wiring for wiring a conductor pattern at the same time as decorating the surface of an article, and a method for decorating the surface.

[0002]

2. Description of the Related Art Conventionally, painting is widely used as a method of decorating the surface of an article. For example, paint is applied to decorate the outer surface of the body of an automobile. The coating process is roughly divided into pretreatment, undercoating (rust-proof coating), intermediate coating, and topcoating, and is a complicated process. In these steps, spray coating by an automatic coating machine is widely used, and an electrostatic coating method is also used to improve coating efficiency.

[0003] Also, especially in the case of automobiles such as long-distance trucks and buses, trains, aircraft, shutters on the outer walls and entrances of buildings, etc., paintings, patterns,
There are also those with characters. Conventionally, these surface decorations are drawn by a method such as spraying or brushing the painted outer surface of the vehicle body. Furthermore, conventionally, metal is previously vapor-deposited on a plastic molded product so that a part of an automobile part appears to be made of metal.

[0004]

As described above, the decoration of the outer surface of an automobile has conventionally been performed by painting.
Conventional coating methods involve complicated steps and are costly. In particular, spray coating has the following serious drawbacks because the paint must be diluted and sprayed with a large amount of solvent. (1) Since the film obtained by one spraying is extremely thin, the spraying operation must be performed many times,
It takes time, cost and time. (2) Since the solvent is dried together with the evaporation of the solvent, a large amount of the solvent is required, which not only increases the cost but also causes a problem of pollution. (3) Of the paint actually sprayed from the nozzle, the rate of adhering to the surface of the article is about 1/10, and waste of material is large. In order to reduce such waste, it is preferable to move the nozzle as far away from the surface as possible, but the strength of the painted surface is reduced and a practical problem arises. (4) Paints and solvents that have not rebounded or hit the surface of the object to be coated become fine powder and float in the air, invading the respiratory organs of the worker or deteriorating the working environment. It can cause pollution problems around factories, giving the painting industry a dark, tight and dirty image. Solving these problems requires a great deal of money and effort, but lacks good workers.
Therefore, there is a major problem of an increase in coating cost.

[0005] Further, in the conventional coating method, usually, one color,
At most two color paint is the limit, photos, paintings, characters,
Complex surface decoration, such as symbols, patterns, and multicolored colors, has the disadvantage of being extremely difficult. Recently, painting has been performed on the body of a long-distance truck or the fuselage of an aircraft, but painting on a very large surface by spraying it is very troublesome, and the cost is greatly increased. There is. In particular, since painting is performed after normal painting is performed, the cost of surface decoration is extremely high. In addition, once decorating, if it gets dirty or gets tired, re-decorating the surface is a lot more troublesome than first decorating, Will increase. In particular, it is concerned with the weather resistance and light resistance of paints.However, it is an extremely advanced technology to repaint partially painted colors that have faded naturally due to sunlight, etc. Is required, and it is naturally extremely expensive. The same applies to a partial repainting due to a small collision or the like. As a result, a large amount of waste is caused, such as discarding the entire unit in favor of high repair costs.

Conventionally, a sheet with a desired decoration has been attached to the surface of a painted body of an automobile. However, a sheet having a large area is limited to a simple pattern. However, there is a disadvantage that it is not uniform, it is difficult to be individualized, and it cannot sufficiently meet a wide range of needs of users. Furthermore, since the method is applied to the surface once coated, there is a disadvantage that the cost increases.

In addition, painting or text is drawn on the surface of a shutter at the entrance of a building for the purpose of advertisement or the like, and a transparent synthetic resin sheet is further coated thereon. After drawing paintings and characters on top, a transparent sheet is attached, which has the drawback that the work is troublesome and the cost increases. Furthermore, as a method of performing surface decoration, a method of decorating the surface of a synthetic resin molded article has been proposed. In this method, a resin is injected in a state in which a decorative sheet is set in a molding mold and molded. And decorating at the same time, for example, it cannot be applied to decorating the surface of the entire body of a car, even if it is only a very small part of the car body. In order to apply it to the decoration of the surface of an already formed article, it is possible to apply the technique of depositing metal on a plastic molded product as described above, but this operation is troublesome and the body of the automobile However, it is not practical to apply to a surface having a large area as described above because the cost increases.

Further, in the process of manufacturing an automobile, there is a step of wiring wires to a vehicle body. Conventionally, a harness in which many wires are bundled is wired along a chassis, and this is performed manually. I have. This task is very cumbersome and difficult to automate. Of course, such wiring work is performed separately from the painting of the chassis surface.

An object of the present invention is to replace the above-described conventional surface decoration by painting with a simple method of simplifying the outer surfaces of vehicles such as automobiles, trains, and aircrafts, and the outer surfaces of buildings and the surfaces of shutters at entrances and exits. It is possible to decorate at low cost by work, and it is possible to decorate a wide variety of pictures, paintings, letters, symbols, reliefs, small sculptures, patterns, colors, etc., and it is possible to individualize,
To provide a painting alternative surface decoration method that can respond to a wide range of needs, and that can be used simultaneously with the painting process, such as the company name or company mark, which was done manually after painting. Things.

Another object of the present invention is to provide a wiring and painting alternative surface decoration method which enables wiring of a conductor to be performed simultaneously with surface decoration, for example, on the surface of an automobile chassis.

[0011]

According to the present invention, there is provided a method for decorating a substitute surface for a coating, which comprises applying a desired photograph, painting, relief, small sculpture, pattern, character, symbol, color, etc., to the surface of an article to be decorated. After covering the decorative sheet with the decorative pattern described above, a transparent or translucent protective sheet is placed on the decorative sheet and fixed. In a preferred embodiment of the method of the present invention, the protective sheet is formed into a tubular shape with a heat-shrinkable material, and after covering the surface of the article with a decorative sheet, the article is wrapped with the protective sheet and heated. The decorative sheet and the protective sheet are fixed to the surface of the article by performing the treatment. When such a heat-shrinkable protective sheet is used, adhesion and heat fusion are not required for fixing, so that the fixing operation can be easily performed and decoration on both the inner and outer surfaces of the article. Can be performed simultaneously, and the cost can be reduced.

[0012] The method for decorating a surface in place of a coating according to the present invention further comprises the steps of providing desired pictures, paintings, reliefs, small sculptures, patterns, characters,
A decorative sheet having a decorative pattern such as a symbol and color is fixed to a back surface of a transparent or translucent protective sheet to form a composite sheet, and then the decorative sheet is a protective sheet and an article to be decorated. The composite sheet is fixed on the surface of the article so as to be interposed between the article and the surface.

[0013] In the method for decorating a substitute surface for painting according to the present invention, a desired decorative pattern such as a photograph, a picture, a pattern, a character, a symbol or a color is further formed on the back surface of a transparent or translucent decorative / protective sheet. Thereafter, the decorative / protective sheet is put on and fixed to the surface of the article. Since the sheet used in this method has both the function as a decorative sheet and the function as a protective sheet, it will be referred to as a decorative / protective sheet in this specification.
Further, for example, when the body of an automobile is decorated with a single black color, the decoration / protection sheet may be constituted by a single black sheet. In such a case, the single sheet itself may be black, or a black layer may be provided on the back surface of the transparent sheet.

The method for decorating a wiring and painting alternative surface according to the present invention, in which the wiring is performed simultaneously with the decoration, is a protective sheet for decorating the surface of an article after arranging a conductor according to a desired pattern on the surface of the article. Is fixed on the surface of the article. In carrying out this method, after arranging the conductive wires, a filler sheet or a decorative sheet may be placed thereon, and a protective sheet may be further placed thereon and fixed. Furthermore, the wiring and painting alternative surface decorating method according to the present invention, in which wiring is performed simultaneously with decorating, forms a desired conductive material pattern on the surface of a decorative sheet made of an electrically insulating material that decorates the surface of an article. After the decorative sheet is put on the surface of the article, an electrically insulating protective sheet is put on the decorative sheet and fixed to the surface of the article. When implementing this method, the formation of the conductive material pattern on the surface of the decorative sheet can be performed by various methods. For example, it can be formed by printing using a conductive ink. Alternatively, the adhesive is printed on the surface of the decorative sheet according to a desired pattern,
It can also be formed by sprinkling and fixing a highly conductive metal powder before it dries. In addition, the conductive material pattern may be seen through the protective sheet, but when it is not desired, the second decorative sheet is placed on the decorative sheet on which the conductive material pattern is formed, and the protective sheet is placed thereon. What is necessary is just to cover it. Alternatively, a decorative pattern may be provided on the surface side of the decorative sheet on which the conductive material pattern is formed.

When the above-described decorating method according to the present invention is carried out, the material and thickness of the decorating sheet and the protective sheet depend on the type of the article to be decorated, the content of the decorating pattern, the necessary durability, An optimum material may be selected from many available materials in consideration of various parameters such as transparency, workability according to the surface shape, and cost, and a material having a necessary thickness may be used. For example, a decorative sheet can be used from a thickness of 0.1 mm to a thickness of about 100 mm. For example, there are cases where only a part of the body of an automobile is framed with aluminum-evaporated parts, but this is also done at the same time as the other parts of the body using a decorative sheet formed with a picture of aluminum color. It can be decorated and cost can be reduced. When a heat-shrinkable protective sheet is used, the surface is deformed along irregularities on the surface, so that a three-dimensional pattern with irregularities can be formed on the surface. For example, when decorating the hood of an automobile, the decoration of the emblem can be performed simultaneously with the decorating of the surface. Furthermore, when a painting is applied as a decorative pattern, a three-dimensional painting can be applied by using a decorative sheet provided with a concavo-convex pattern according to the content of the painting.

Further, according to the method for decorating a substitute surface of a paint of the present invention, a destination address, a description about the contents, a picture, and the like are formed on a decorative sheet on the surface of a packing material such as a cardboard box or a wooden box. This can be fixed to the surface together with the protective sheet. In this case, the sheet may be fixed so as to cover the entire packing material, or the sheet may be fixed to a part of the surface of the packing material. If the entire packing material is covered with a sheet, the surface of the packing material itself is left as it is without any entry, so if there is no damage, it can be reused as it is, which has the advantage of protecting the natural environment. is there. Of course, what was conventionally printed on the packaging material at the flat stage, but the method of the present invention also performs printing in the packaging process at the time of final export or export. Depending on the direction of reduction.

In this example, a case where a hood (front hood) of a passenger car is decorated will be described as an example.
FIG. 2 is a sectional view of a bonnet whose surface is decorated by the method of this embodiment. First, in step S1, the surface of the steel sheet 1 pressed into a desired shape to be used as a material of the bonnet is subjected to a base treatment to remove foreign substances on the surface and clean the surface. Next, in step S2, the decorative sheet 2 on which a decorative pattern to be formed on the surface of the bonnet, for example, a color or black-and-white photograph of a landscape such as a sunrise, sunset, mountains, or a seaside, is recorded. Cover. In this case, the dimension of the decorative sheet 2 is set to be slightly larger than the dimension of the steel sheet so that the peripheral edge of the decorative sheet covers the back surface of the steel sheet. In this example, the decorative sheet 2 on which the photograph is recorded is used, but this recording can be performed by printing or printing. Further, step S
In 3, an insulator 3 for sound insulation and vibration isolation is put on the back surface of the steel plate 1. The material of the insulator 3 may be a conventionally used material.

Next, in step S4, a protective sheet 4 formed in a cylindrical shape is put on the whole. This protective sheet 4 is formed of a transparent or translucent heat-shrinkable resin.
Finally, in step S5, the whole is heated to shrink the protective sheet 4. Due to this shrinkage, the decorative sheet 2, the insulator 3, and the protective sheet 4 are firmly fixed to the steel sheet 1. During the contraction, these materials are deformed according to the contour of the steel plate 1, so that these materials can be brought into close contact with the steel plate. As described above, in this example, the outer surface of the hood of the automobile can be decorated, and at the same time, an insulator or the like can be attached to the back surface of the bonnet simultaneously with the decoration of the outer surface. This operation is significantly simpler and much cheaper than the conventional operation. Further, the decoration of the outer surface can easily respond to various needs of the user (including not only colors but also characters, etc.) only by changing the photograph recorded on the decoration sheet 2.

FIG. 3 is a flow chart showing the sequential steps in the second embodiment of the method for decorating a coating alternative surface according to the present invention, and FIG. 4 is a sectional view showing the structure of the final article formed by this example. is there. First, in step S1, a base treatment of the surface of the article 11 whose surface is to be decorated is performed.
Next, in step S2, the decorative sheet 12 having a desired photograph on the surface is fixed to the back surface of the transparent or translucent protective sheet 13 to form a composite sheet. For fixing these sheets, an appropriate adhesive may be used, or these sheets may be overlapped and heated and heat-sealed,
An optimum method may be adopted according to the material of the sheet to be used. Finally, in step S3, the composite sheet 12,

Also in this example, desired decoration can be easily and inexpensively applied to the surface of the article 11, and the content of the decoration is a decoration sheet.
Various decorations are possible by selecting 12 appropriately.

FIG. 5 is a flow chart showing the sequential steps in a third embodiment of the method for decorating a coating alternative surface according to the present invention. The structure of the final product formed by this example is similar to that shown in FIG. First, in step S1, a base treatment of the surface of the article to be decorated is performed. Next, in step S2, desired decoration is formed by printing or printing on the back surface of the decoration / protection sheet formed into a tubular shape with a transparent or translucent heat-shrinkable material. In this case, it is preferable to turn the front and back of the tubular decoration / protection sheet. Next, in step S3, after the front and back of the decoration / protection sheet are returned to the original, in step S4, the decoration
An article is covered so that an article may be wrapped with a protection sheet. Lastly, in step S5, the decorating / protecting sheet is shrunk by performing a heat treatment and fixed to the article. When the protective sheet is put on the article in step S4, the desired decorative portion is made to come to the desired surface of the article. Since the sheet used in this example has both a decoration function and a protection function, it is referred to as a decoration / protection sheet. In this embodiment, the decorating / protecting sheet is decorated by inverting the front and back, but the decorating can be performed by a method such as direct printing on the back surface of the tubular decorating / protecting sheet. Does not require a step of turning over.

Next, a surface decorating method according to the present invention for decorating the surface of an article and at the same time wiring a conductor on the inner surface of the main body will be described. FIG. 6 is a flowchart showing the sequential steps of one embodiment of such a surface decoration method, and FIG. 7 is a cross-sectional view showing the structure of a final product obtained by this method. In this example, it is assumed that the surface of the chassis of the automobile is decorated and wiring is performed along the inner surface of the chassis. First, in step S1, a base treatment is performed on the surface and inner surface of the chassis to be decorated. Next, in step S2, a conductor 23 in which a copper core wire 21 is covered with an insulating sheath 22 is temporarily fixed to the inner surface of the chassis 24 as shown in FIG. FIG. 7 shows only the inner surface of the chassis. This temporary fixing can be performed using, for example, an adhesive, or a temporary and inexpensive material such as a vinyl tape may be used for temporary fixing. Next, in step S3, a filler sheet 25 made of a deformable insulating material is put on the conductor 23. The purpose of the filler sheet 25 is to flatten the surface of the portion where the wires are wired and to prevent displacement of the wires 23.For example, when a copper wire having a small diameter or a copper wire having a flat cross section is used. May be omitted. Finally, in step S4, the protection sheet 26 is put on and fixed to the filling sheet 25. It is not necessary to decorate the car chassis 24 with special photos or paintings, but symbols or patterns that guide the work related to the conductors are formed on the back surface of the protective sheet 26 by a printing method or the like. You can also.

FIG. 8 is a flowchart showing the sequential steps in another embodiment of the surface decorating method according to the present invention in which conductor wiring is performed, and FIG. 9 is a sectional view showing the structure of the final product. In this embodiment, a protective sheet having a wiring pattern formed of a conductive material is fixed to the inner surface of an automobile chassis instead of using a conductive wire. In the present example, desired decoration is applied to the surface of the chassis at the same time as performing such wiring. First, in step S1, a first decorative sheet 31 having a desired decoration is prepared and a conductive material is applied according to a desired wiring pattern to form a conductive pattern 33 on the surface. A decorative sheet 32 is prepared. The conductive pattern 33 is formed by mixing a highly conductive metal powder such as copper or aluminum with an adhesive according to a desired pattern.
After applying to the surface of the decorative sheet 32 or printing an adhesive on the surface, it can be performed by sprinkling metal powder while not drying. Therefore, if the conductivity is good, only a small amount of material can be used, which can contribute to the effective use of resources. As described above, the present invention also provides a method for establishing a wiring method with an extremely small volume.

Next, in step S2, the articles to be decorated, that is, the surface 34a and the inner surface 34b of the chassis 34 are subjected to a base treatment. Further, in step S3, the above-described first decorative sheet 31 is mounted on the surface 34a of the chassis 34, and the second decorative sheet 32 having the conductive pattern 33 formed on the surface is covered on the inner surface 34b of the chassis 34. Next, in step S4, a cylindrical protective sheet 35 made of a transparent or translucent material having an electrical insulating property and a heat shrink property is covered so as to wrap the first and second decorative sheets 31 and 32. Finally, in step S5, a heat treatment is performed to shrink the protective sheet 35 so that the first and second decorative sheets 31 and 32 and the protective sheet 35 are attached to the surface 34 of the chassis 34.
a and the inner surface 34b. Since the conductor patterns 33 are both held between the electrically insulating second decorative sheet 32 and the protective sheet 35, safety is ensured. In this embodiment, since no conducting wire is used as compared with the previous embodiment, there is an advantage that wiring work is not required and cost can be further reduced. If it is inappropriate to apply a large current to a conductive pattern formed by applying a conductive material, the conductive pattern and a conventional conductive wire that has been used can be mixed. That is, after the conductor is wired on the surface of the decorative sheet on which the conductor pattern is formed, the protective sheet can be covered. The technology of this embodiment of the present invention can also be applied to a switchboard and a control panel of a machine called a "machine", whereby the switchboard and the control panel can be made thinner. Further, in this embodiment, since a cylindrical one is used as the protection sheet 35, the decoration on the chassis surface and the wiring to the inner surface of the chassis can be performed simultaneously, and the work efficiency is improved,
There is an advantage that the cost can be reduced.

FIG. 10 is a sectional view showing a chassis decorated by a modification of the fifth embodiment of the wiring and surface decorating method according to the present invention shown in FIGS. 8 and 9. In this example,
After first applying an insulating sheet 36 to the inner surface 34b of the chassis 34,
A second decorative sheet 32 having a conductor pattern 33 formed on the back surface is prepared, and the first decorative sheet 31 is applied to the front surface 34a of the chassis 34 and the second decorative sheet 31 is placed on the insulating sheet 36 applied to the inner surface 34b. The decorative sheet 32 is applied so that the conductor pattern 33 is on the inner side, and further covered with a cylindrical protective sheet 35 so as to cover the first and second decorative sheets 31 and 32, and is shrunk by heating. It is. In this example, since the conductor pattern 33 is formed on the insulating sheet 36, it is not necessary to make one of the second decorative sheet 32 and the protective sheet 35 from an electrically insulating material. There is an advantage that the range is expanded.

The present invention is not limited to the above-described embodiment, but can be variously modified and modified. For example, in the above-described embodiment, the case where decoration is performed on the outer surface or the chassis of the passenger car has been described.
Vehicles such as trucks and buses, vehicles such as trains and aircraft, and exterior surfaces of buildings, shutters at doorways, and surfaces of packing materials can also be decorated. Further, in the example shown in FIG. 2, the decoration of the outer surface of the hood of the passenger car and the attachment of the insulator to the inner surface are performed simultaneously. However, the decoration and the lining of the outer surface of the door are performed simultaneously. You can also. In this case, after the decorative sheet is covered on the surface of the door steel plate, the back surface of the steel plate can be covered with a lining material, for example, a textile, and finally a protective sheet can be covered on the whole and fixed. Further, by forming irregularities on the surface of the decorative sheet and coloring the surface, a decorative pattern having a three-dimensional effect can be provided. Such irregularities can be formed, for example, by a well-known photographic etching method using a photosensitive resin.

[0026]

As described above, according to the present invention, the decoration of the surface can be performed very easily and at low cost as compared with the conventional coating, and the contents of the decoration can be reduced to photographs, pictures, reliefs, A wide variety of decorative patterns, such as sculptures, patterns, characters, symbols, colors, etc., can be used to sufficiently meet various needs of users. Further, when the decoration of the outer surface and the decoration of the inner surface are performed simultaneously, the working efficiency is further improved and the cost is further reduced. In addition, in the method in which the wiring of the conductor or the conductor pattern is performed simultaneously with the decoration of the surface, the wiring work of the conventional conductor harness is not required, the work efficiency is improved, and the cost can be reduced. Further, by employing the wiring technology of the conductor pattern according to the present invention, it is possible to easily manufacture the switchboard and the control panel, reduce the cost, and further reduce the thickness of these products.
