Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a decorative member used as, for example, an automobile emblem, a decorative molding, a name plate 1, etc.

[Prior art]

Decorative members include moldings and name plates displaying emblems, letters, etc. that are attached to the exterior of automobiles. This emblem is a graphic representation of the vehicle name, company name, roadway, etc. Molding is a wire or band-shaped thing used for the interior and exterior of cars. A name plate expresses the car name, company name, etc. in characters.

This emblem, molding, nameplate etc. are usually
It has been aesthetically treated to make it easier to see, but the extent of this is not necessarily sufficient. Therefore, in the industrial world, improvements have been made to make emblems, moldings, name plates, etc. easier to see.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a decorative member that is easy to see for a viewer.

[Structure of the invention]

The decorative member of the present invention includes a translucent base, a first decorative body provided on the surface of the base, and a portion of the back surface of the base excluding the portion corresponding to the first decorative body. and a second decorative body formed on the back surface of the base so as to cover the first decorative body.

The decorative member of the present invention is mainly used for aesthetically treated emblems, moldings, name plates, etc. used for vehicles, particularly automobiles, and in some cases, license plates. Note that the decorative member of the present invention is not limited to emblems, moldings, name plates, and license plates, and may be used for other decorative members.

The base body, which is a component of the present invention, is usually the main body of a decorative member, and is a member having a constant thickness and having a front surface and a back surface. When the decorative member is a molding, the base body is usually an elongated body. Further, when the decorative member is a name plate, the base body is usually rectangular. The substrate has a translucent property that allows light to pass therethrough. The higher the degree of light transmission, the better. Therefore, it is desirable that the substrate has good transparency. Particularly desirable is a completely transparent body. Therefore, the substrate is preferably made of transparent glass or transparent resin. The substrate is preferably colorless and transparent, but may be colored and transparent or semitransparent depending on the case. The base material is, for example, vinyl chloride resin, AB
It is preferable to make it from S resin, polycarbonate resin, or acrylic resin. The shape, thickness, and size of the J3 base are variously set depending on the conditions of use. When the decorative member of the present invention is used as an emblem or a name plate, the thickness of the base is preferably about 3 to 5 Qmm. The shape of the base body is preferably a flat plate, and may be lens-shaped depending on the case.

The first decorative body, which is a component of the present invention, is provided on the surface located on the viewer side, that is, the surface of the base body. The first decorative object is a member such as a character or a figure that has been aesthetically treated. The degree of aesthetic treatment is not particularly critical, but it is desirable that it match the taste of the person.

The first decorative body is preferably one with strong light-shielding properties. Note that the second decorative body may be constructed by forming a metallic coating film on the surface of the base, or may be constructed by plating, vapor deposition, sputtering, printing, or the like. Printing is preferably carried out by screen printing using ink or paint that does not transmit light.

When the decorative member of the present invention is used as an emblem or a name plate 1, the symbols forming the emblem and characters such as a car name become the first decorative object. The first decoration uses letters, numbers, figures, patterns, symbols, etc. The characters may be any foreign language characters such as the alphabet, katano, hiragana, kanji, or Greek characters. The numbers may be honorary numerals or Roman numerals. Any figure, pattern, or symbol is fine.

The thickness of the first decorative body may be thin. When the decorative member of the present invention is used as an automobile emblem, molding, or name plate, the thickness of the first decorative body is preferably 2 to 4 mm.

The second decorative body, which is a component of the present invention, is a background member of the first decorative body. Therefore, it is desirable that the color of the second decorative body is different from the color of the first decorative body. For example, when the first decorative body is red, the second decorative body may be black, white, blue, etc. The second decorative body preferably has strong light-shielding properties. Further, the second decorative body needs to be large enough to cover the first decorative body. This is because the second decorated body becomes the background of the first decorated body. Therefore, the second decoration body is preferably formed on almost the entire back surface of the base body.

In the decorative member of the present invention, the first decorative body is provided on the front surface of the base, and the second decorative body is formed on the opposite side, the back surface of the base.

Here, the second decorative body is not formed in a portion of the back surface of the base body that corresponds to the first decorative body.

In this way, in the decorative member of the present invention, since the second decorative body is not formed on the back surface of the base body at a portion corresponding to the first decorative body, light can be emitted from the rear of the back surface of the base body. If the irradiation is deviated, the light will pass through the above-mentioned portion as it is, and will further pass through the interior of the substrate which has translucency. However, the light hitting the second decorative member is blocked by the second decorative member.

The second decorative body is preferably constructed by forming a thin film on the back surface of the base. The thickness of the thin film is 0.05-5
Approximately 0μ is preferable. The thin film may be formed by a PVD method or CVD method such as vapor deposition or sputtering, or by painting, plating, or the like. The material of the thin film may be determined as appropriate, but metal chromium is preferable, for example. When the base is an electrical insulator, a thin film may be formed by electroless plating, and this may be used as the second additive body. Incidentally, when several first lIO sieves are provided, a plurality of second decorations may be provided. For example, when the first decorative bodies provided on the surface of the base body are three letters of the alphabet A, B, and C, the number of second decorative bodies is correspondingly three. One of the second decorative bodies is placed behind the letter A on the back side of the base, and the other second decorative body is placed behind the letter B on the back side of the base. The remaining second decorative body is provided on the back side of the base body behind the letter C.

Now, a third decorative body may be provided on the back surface of the base body on which the second decorative body is not formed. This third decorative body is
The color is different from that of the first decorative body and the second decorative body. As the third decorative body, it is preferable to use a luminous body that emits light. A typical light emitting body is a panel. The Eshi panel is called an electroluminescence device, and is a planar light-emitting device that utilizes electroluminescence, which emits light when an electric field is applied to the phosphor. This is formed by providing electrodes on both sides of a luminescent layer containing zinc sulfide or the like formed into a panel shape. E [When voltage is applied to the electrodes of the panel, the light-emitting layer emits light. The brightness of an EL panel is usually not bright enough to be used for lighting, but it is bright enough to make characters visible from a distance even at night. EL panels emit light from a flat surface, so they have a large viewing range (-) compared to other displays.
CIt has many advantages such as good visibility, thin and light weight (typically about 1 mm thick), easy integration into automobiles, impact resistance, and extremely low power consumption. There is ÷÷.

EL panels can be manufactured using thin film types with a light-emitting layer and M pole deposited on them, organic dispersion types, hollow types, and flexible types.
[The panel's emitted light color can be freely selected from blue to orange, such as green, blue-green, blue, red, orange, white, yellow-white, etc.
Select as appropriate for the decorative member. Sho 11EL
When the panel is used for an emblem (11) molding etc. that is exposed to wind and rain, it is desirable to cover it with a moisture-proof coating. For example, the EL panel may be coated with a protective film, or the EL panel may be housed in a container to prevent moisture. As other light emitters, a light reflecting body such as a mirror, or a light emitting diode may be used. The light reflecting body may be one that causes random reflection.

As described above, when a light emitter, which is a third decoration, is provided on the back surface of the base where the second decoration is not formed, that is, on the above-mentioned part, (if the viewer views the decorative member from an oblique direction) if you see,
As will be explained in the examples below, the first decoration body is
The second decorated body and the third IJII appear to be floating against the background of the light emission.

In particular, when the first decorative body is an EL panel, the light emitted from the electroluminescent EL panel is used as a backdrop, making it easier for the viewer to see the first decorative body. Therefore, if applied to the emblem, molding, or name plate of a car, even when the car is traveling at a relatively high speed at night, viewers can easily see the figures and letters on the emblem, molding, or name plate. Become. Furthermore, since the background is the light emitted by the 6m electroluminescent panel, the design effect is also good.

(Effects of the Invention) The decorative member of the present invention includes a translucent base, a first decorative body provided on the surface of the base, and a second decorative body provided on the back surface of the base. A second decorative body is formed on the back surface of the base body so as to cover the first decorative body, except for corresponding parts. When the decorative member is viewed from an oblique direction, the first decorative body appears to be floating, with the back side of the base corresponding to the second decorative body and the first decorative body being the silver back. Particularly when viewed from an oblique direction, the first decorative body overlaps the target area and appears double, as illustrated in Figure 1, and has a strong visual appeal to the viewer, making it difficult for the viewer to see the first decoration. The first decorative body becomes easier to see. Moreover, its design effect is also good.

〔Example〕

FIG. 1 J3 and FIG. 2 are diagrams showing a decorative member according to an embodiment of the present invention. FIG. 1 is a perspective view, and FIG. 2 is a sectional view taken along the obliquely inclined outer edge of the letter 2 of △.

Since this decorative member is constructed to have a good design effect, it is mainly used for automobile decorative moldings. The decorative member of this example includes a flat J base 1, a first decorative body 2 provided on the surface 1a of the base 1,
A thin film 3 as a second decorative body is provided over almost the entire back surface 1b of the base 1, and an EL light emitting diode (EL) as a third decorative body for surface emission is provided on the outer surface of the thin film 3.
It is equipped with panel 4. Here, on the back surface 1b of the base body 1, the thin film 3 is not formed on a portion 5 corresponding to the characters 2. Therefore, when the base 1 is viewed from the rear of the back surface 1b, the region 5 where the thin film 3 is not formed is designated as A.

In this example, the substrate 1 has a thickness of 2.5 to 3.5 mm, is made of transparent resin, and is colorless and transparent. This substrate 1 is almost completely transparent.

The letter A 2 has a thickness of 30 to 50 microns, is made from acrylic paint, and has a black color.

The thin film 3 has a thickness of 30 to 50 μm and is made of acrylic paint, and its color is white, unlike the color of the characters 2. Both the letters 2 and the thin film 3 have excellent light-shielding properties and block light.
υHas the property of not being able to pass through anything or at all. [L panel 4
is an organic dispersion type, and its luminescent color is green. This EL panel 4 has 60 pols 1~. At 400 Hz, the brightness is approximately 107-transverts. Incidentally, when the EL panel 4 is installed in a car, since the car battery usually has a capacity of 12 volts or more, it is preferable to use a booster to increase the applied voltage.

In the decorative member J3 of this embodiment having such a structure, when the EL panel 4 is energized and causes it to emit green electroluminescence, the light from the peripheral edge 4a of the EL panel 4 is absorbed by the light-shielding member. Since it hits the thin film 3 which is , it does not proceed any further. However, E
The light from the central part 4b of the panel 4 passes through the part 5 of the back surface of the base 1 corresponding to the first decorative body 2, and then passes through the inside of the transparent base 1, and passes through the light-shielding characters. This corresponds to the back surface 2a of 2. As a result, when a viewer looks from the outside on the decorative portion side, the letter A 2 itself does not emit any light, but the outer edge of the black letter A 2 appears to emit green light.

When a viewer on the front side of the decorative member looks at the decorative member with the EL panel 4 emitting electroluminescence in this manner, the outer edge of the black letter 2 of A is υ2-recognizable J: El panel 4 Because it appears to emit green light, it has a strong visual appeal to the viewer, and as a result, the character 2 is easier for the viewer to see than conventional emblems, moldings, and nameplates.

In particular, when the viewer views from an oblique direction as shown in Figure 2, the black letter A 2 is visible within the viewing angle θ1,
Also, V of visual angle θ2! The green electroluminescent color of the EL panel 4 can be seen in the circle. This can be expressed graphically as shown in FIG. 1, where a portion 5 behind the letter A 2 appears to emit green light, which is the emission color of the EL panel 4. Therefore, it has a stronger visual appeal to viewers than conventional emblems, moldings, name plates, and number plates. Therefore, even when the decorative member of this example is used as an emblem, name plate 1 to number plate, or license plate of a car running at high speed, the viewer can easily see the letter A 2.

Furthermore, in this embodiment, the luminescent color (green) of the electroluminescent EL panel 4, which is green, which is a different color from the color of the characters 2 and the color of the thin film 3, is visible at the outer edge of the characters 2, so that the design effect is improved. Good. Especially at night, when viewed from an angle, the outer edge of the letter 2 of the letter A glows green, creating a unique design effect.

FIG. 3 shows another embodiment of the invention. This embodiment has almost the same structure as the above-mentioned embodiment, but the transparent base 11
The difference is that a plurality of square-shaped second decoration bodies 13 are provided on the back surface of the . As shown in FIG. 3, this second decorative body 13 is
It is large enough to cover the first decorative body 12 which is the letter G. In this example as well, when the EL panel (not shown) provided on the back side of the base 11 is made to emit light, the outer edges of the first decorative body 12, which are the letters T and G, appear to emit light.
