DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a lamp for an automobile, which is provided to improve the appearance of the lamp when viewed from the front by covering a gap between the lamp body and a reflector. The present invention relates to a decorative member called an extension. Specifically, the aim was to further enhance the design effect of automotive lighting by expressing clear and good-looking metallic characters and marks on the surface of such extensions. TECHNICAL FIELD The present invention relates to a technique for preventing characters or marks in a metallic tone from peeling off or disappearing.

[0002]

2. Description of the Related Art Conventionally, when a metal-like character or mark is expressed on the surface of a decorative member called an extension which is provided to improve the appearance of a lamp from the front, a painted surface is used. A sticker printed with metallic characters and marks was pasted on top of the.

[0003]

However, the method of attaching a sticker on which metallic characters or marks are printed as described above has a problem that the sticker is peeled off. This is because in the case of an automotive lamp having a light source inside and a front surface covered with a lens, the extension to which the seal is attached becomes extremely hot. Also,
This is because the seal is easily peeled off due to a difference in the coefficient of thermal expansion based on the difference in the material of the seal and the extension between when the light is on and when the light is off. In particular, when a metal seal is bent and affixed to the curved surface portion of the extension in accordance with the curved surface, a strong stress is always applied to the bent and affixed seal, and therefore, the seal is easily peeled off from the end of the seal.

Accordingly, the present invention overcomes the above-mentioned problems, and even when a metal-like character or mark is expressed on the surface of a decorative member of an automotive lamp called an extension, An object of the present invention is to prevent a character or a mark portion of a key from peeling off or disappearing.

[0005]

In order to solve the above-mentioned problems, a decorative member of a vehicle lamp according to the present invention has a non-painted portion formed in a painted portion to expose a reflection surface of a base. The method for manufacturing a decorative member of a vehicle lamp according to the present invention comprises:
A metal member is formed on the decorative member to form a reflective surface, and then a sticker on which a character and a mark are molded is pasted on the reflective surface. The paint and then the seal were peeled off to form letters and marks consisting of areas where the reflective surface was exposed in the painted area.

Therefore, in the decorative member of the vehicle lamp and the method of manufacturing the same according to the present invention, the metallic characters and marks in the painted portion have only the underlying reflective surface exposed. There is no need to worry about the sticker peeling off, as in the case where a sticker with characters or marks printed on a painted surface.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a decorative member of a vehicular lamp of the present invention and a method of manufacturing the same.

The drawings show the present invention applied to an extension of an automotive headlamp.

The extension 1 shown in FIG. 1 is a decorative member provided to improve the appearance of the lamp when viewed from the front by covering a gap between a lamp body (not shown) and the reflector. .

As shown in FIG. 1, the overall shape of the extension 1 as viewed from the front has a substantially square shape with rounded corners, and comprises an aluminum deposition portion 2 and a metallic coating portion 3.

The aluminum vapor deposition section 2 comprises an aluminum vapor deposition surface 3, and reflects light from a light source (not shown) toward the front of the lamp.

The metallic coating portion 4 is a portion where the metallic coating 5 is applied on the aluminum vapor deposition surface 3 and enhances the design effect when the lamp is viewed from the front.

A metallic character (mark) 6 is expressed in the metallic coating portion 4. As shown in FIGS. 1 and 2, the metallic character 6 is formed by leaving the metallic coating 5 only on the character-shaped portion so that the underlying aluminum vapor-deposited surface 3 is exposed only on the character-shaped portion. It was made.

As shown in FIGS. 1 and 2, the metallic character 6 is formed in a portion near the peripheral edge portion of the extension 1 and in a portion having a curved surface.

The front surface of the extension 1 is covered with a front lens 7 having a substantially square shape as in the case of the extension 1 (see FIG. 1).

As the front lens 7, a lens which is almost transparent is used (see FIG. 1). Extension 1
If the metallic characters 6 formed on the metallic painted portion 4 cannot be clearly seen from the front of the lamp through the front lens 7, the meaning of forming the metallic characters on the metallic painted portion 4 for the purpose of design effect is bothersome. Is no longer there.

Thus, the metallic characters (marks) 6 expressed on the metallic coating portion 4 of the above-described extension 1 of the automotive headlamp are formed as follows.
3 to 9 are schematic diagrams for sequentially explaining a method of forming the metal character 6.

First, a masking seal 8 is prepared in advance.

The masking seal 8 has a back surface of a seal 9 in the form of characters and marks attached to a release paper 11 via a seal adhesive 10 and a front surface of the seal 9 via an application adhesive 12. Application film 1
3 (see FIG. 3).

Then, for the extension 1 (work) to which the above-mentioned seal 9 is to be affixed, aluminum deposition is first performed on the entire surface to form an aluminum deposition surface 3 (see FIG. 4).

Next, with respect to the masking seal 8 prepared in advance, first, only the release paper 11 is peeled off (see FIG. 5).

In this case, the bonding force between the seal 9 and the release paper 11 by the seal adhesive 10 is weak, and the bonding force between the seal 9 and the application film 13 by the application adhesive 12 is stronger. When the sticker 9 is pulled in a direction away from the pattern paper 11, the seal 9 is peeled off from the release paper 11 in a state of being stuck on the application film 13.

The reason why the adhesive force between the seal 9 and the release paper 11 by the seal adhesive 10 is weak is that the seal adhesive 10 is easily peeled off from the release paper 11. The seal adhesive 10 is directly adhered to the seal 9 peeled off from the release paper 11 (FIG. 5).
reference).

Next, the masking seal 8 peeled from the release paper 11 in this manner is affixed on the aluminum deposition surface 3 (see FIG. 4) formed on the extension 1 (work), and then the application film 13 and pull it off (see FIG. 6).

In this case, the bonding strength between the seal 9 and the aluminum deposition surface 3 of the extension 1 (work) by the seal adhesive 10 is considerably strong, and the application adhesive 1
2, the bonding force between the seal 9 and the application film 13 is weaker.
Is pulled away from the extension 1 (work), only the application film 13 is peeled off from the seal 9 and the seal 9 remains attached to the aluminum deposition surface 3 of the extension 1 (work).

Since the application adhesive 12 is more easily peeled off from the seal 9 than from the application film 13, when the application film 13 is peeled off from the seal 9, the application adhesive 12 adheres to the application film 13. . Therefore, the upper surface of the seal 9 is exposed (see FIG. 6).

Next, a metallic coating 5 is applied on the aluminum-deposited surface 3 of the extension 1 (work) to which the seal 9 on which the characters and marks are molded is attached (see FIG. 7).

In this case, since the upper surface of the seal 9 attached to the aluminum vapor-deposited surface 3 is exposed as described above, when looking at the portion to which the seal 9 is attached, the metallic coating 5 is not sealed. 9 (see FIG. 7).

Next, after temporarily drying the metal-coated surface by drying at room temperature, a cellophane tape 14 is attached to the metal-coated surface of the upper surface of the seal 9, and then the cellophane tape 14 is pulled off (FIG. 8). reference).

In this case, since the adhesive force of the cellophane tape 14 is extremely strong, the cellophane tape 14 and the seal 9
Has a very strong bond with metallic painted surfaces. Therefore, since the bonding force between the seal 9 and the aluminum deposition surface 3 of the extension 1 (work) by the seal adhesive 10 is weaker, when the cellophane tape 14 is pulled in a direction away from the extension 1 (work), the upper surface becomes The metallic-coated seal 9 is peeled off from the aluminum-deposited surface 3 of the extension 1 (work) while the metallic-coated surface is kept adhered to the cellophane tape 14.

Since the seal adhesive 10 is more easily peeled from the aluminum vapor deposition surface 3 of the extension 1 (work) than the seal 9, the seal adhesive 10 is peeled off from the aluminum vapor deposition surface 3 of the extension 1 (work). The seal adhesive 10 adheres to the seal 9.
Therefore, the aluminum deposition surface 3 is exposed at the portion where the seal 9 in which the characters and marks are molded is attached (see FIG. 8). Therefore, metal-like characters and marks 6 are expressed in the metallic coating portion 4 of the extension 1 (see FIG. 9).

Finally, the extension 1 (work) is placed in a drying oven and the main surface of the metallic coated surface is dried to finish the process.

As described above, characters (marks) 6 are formed in the metallic coating portion 4 of the extension 1 by painting and leaving the aluminum vapor deposition surface 3 as a base (FIG. 6). 9).

In this case, an aluminum-deposited surface 3 is formed as a base of the metallic coating portion 4, and this aluminum-deposited surface 3 is exposed, so that the exposed portion looks like a metallic shine. Therefore, metal-like characters (marks) 6 can be formed in the metallic coating portion 4 (see FIG. 9).

It should be noted that the specific shape or configuration of each part shown in the above-described embodiment is merely an example of the embodiment for carrying out the present invention.
Therefore, the technical scope of the present invention should not be interpreted in a limited manner.

[0036]

As is apparent from the above description, the decorative member of the vehicular lamp of the present invention is disposed inside the front lens and forms a metal-deposited reflection surface on the base to form the reflection surface. By forming a non-painted part in the painted part, in the decorative part of the vehicle lamp, which is partly a reflective part and the other part of the reflective surface is further painted and becomes a painted part, Characters and marks composed of an area exposing the underlying reflective surface are formed, and the method of manufacturing a decorative member for a vehicle lighting device of the present invention firstly forms a reflective surface by performing metal evaporation on the decorative member. , Then the letters on the reflective surface,
Paste the seal with the mark, then apply further paint on the reflective surface including the part where the seal was pasted,
By removing the seal, a character or a mark is formed in the painted portion, which is composed of a region where the reflection surface is exposed.

Therefore, in the decorative member of the vehicle lamp and the method of manufacturing the same according to the present invention, the metallic characters and marks formed in the painted portion of the decorative member are exposed on the underlying metal-deposited reflective surface. Because it is visible, there is no fear that the sticker will peel off, as in the case where a sticker printed with metallic characters or marks is applied on the painted part.

According to the second and fourth aspects of the present invention, characters and marks are formed on the curved surface of the decorative member where stress is easily applied to the pasted seal. Since it is not necessary to attach a seal on which characters and marks are printed, metal-like characters and marks can be easily expressed on such portions.
