<Outline of luminous ornament 1>
Next, the outline of the light emitting ornament 1 will be described with reference to FIGS. 2A and 2B. The light emitting ornament 1 is a decorative component for a vehicle door lining, which is attached to a portion of the vehicle interior side of the door base 4 that is aligned with the pull handle 5. The light emitting ornament 1 functions as a lighting device in the vehicle door lining R and is turned on when the vehicle interior becomes dark at night or the like. With the illumination function of the light emitting ornament 1, for example, when the door is open, it is possible to inform a vehicle behind or a person that the vehicle is in the door open state.

When the light emitting ornament 1 exerts the illumination function, only the lower portion of the light emitting ornament 1 emits light, and the upper portion of the light emitting ornament 1 does not emit light. Specifically, as shown in FIG. 2A, the light emitting ornament 1 has a knife-like outer shape that is long in the front-rear direction of the vehicle, and has a lower end portion at a position somewhat rearward of the front end. The light emitting region 1a is formed in a substantially triangular shape. A light source is arranged outside the vehicle in the light emitting area 1a, and when the light source is turned on, the light emitting area 1a emits light with a predetermined brightness.

The non-light emitting area 1b is adjacent to the light emitting area 1a above the light emitting area 1a and does not emit light even when the light source of the light emitting ornament 1 is turned on.

Further, the light emitting ornament 1 functions as a decorative component for improving the design of the door in a situation where the illumination function is not required such as daytime. In the light emitting ornament 1, the light emitting area 1a in a non-light emitting state has a different appearance from the non-light emitting area 1b. That is, the decoration style of the interior surface of the light emitting area 1a is a metallically colored surface, while the decoration style of the interior surface of the non-light emitting area 1b has a wood grain or carbon pattern. It is the surface. Here, the decoration style means visual characteristics such as coloration, pattern, luster, and texture of the surface that appear due to the decoration treatment applied to the surface.

As described above, since the decoration style of the vehicle interior surface of the light emitting area 1a and the decoration style of the vehicle interior surface of the non-light emitting area 1b are different, the design of the door is improved by combining the different decoration styles. It will be.

<Structure of luminous ornament 1>
Next, the configuration of the light emitting ornament 1 will be described in detail with reference to the drawings. As shown in FIG. 3, the light emitting ornament 1 has an ornament unit 10 and a light source unit 30 as main components. The ornament unit 10 is a plate-shaped member exposed inside the vehicle. That is, the ornament unit 10 defines the outer shape of the light emitting ornament 1, and is positioned inside the vehicle to exhibit the decorative property of the light emitting ornament 1.

The ornament unit 10 corresponds to a decoration unit and has a portion that emits light when the light source of the light emitting ornament 1 is turned on and a portion that does not emit light. The portion of the ornament unit 10 that does not emit light is the non-light emitting area 1b. On the other hand, in the ornament unit 10, the light emitting region 10a, which is a light emitting portion, is a part of the light emitting region 1a, and corresponds to a portion of the light emitting region 1a excluding the light source unit 30. As described above, in the present embodiment, the non-light emitting area 1b and the light emitting area 10a are integrated as the ornament unit 10.

The ornament unit 10 is fixed to the vehicle inner surface of the door base 4. Note that both the fixing method using screws and the fixing method using snap fit engagement are used to fix the ornament unit 10 to the door base 4.

The light source unit 30 corresponds to an illuminating body, has a lamp 31 as a light source, and a light guide 32 having an emission surface 32 a that emits light from the lamp 31, and is provided on the vehicle exterior side of the ornament unit 10. It is arranged. That is, the light source unit 30 is arranged at a position sandwiched between the door base 4 corresponding to the base member and the ornament unit 10 corresponding to the decoration unit.

More specifically, the light source unit 30 is attached to the surface of the ornament unit 10, which is outside the light emitting region 10a and faces the door base 4. The light source unit 30 is assembled to the light emitting region 10a by a snap fitting engagement fixing method.

In this way, the light source unit 30 is arranged at a position sandwiched between the door base 4 and the ornament unit 10, so that the light source unit 30 can be made compact in a limited space such as the inside of a vehicle door. Can be placed. As a result, the concealment of the lamp 31 included in the light source unit 30 as the light source can be effectively realized, and thus the stealth property showing the property of concealing the existence of the light emitting region 1a in a situation where the illumination function is not required such as daytime is improved. Hereinafter, each of the ornament unit 10 and the light source unit 30 will be described in more detail.

<Structure of ornament unit 10>
As shown in FIGS. 3 and 4, the ornament unit 10 has a light emitting region 10a and a non-light emitting region 1b. Each of the light emitting region 10a and the non-light emitting region 1b includes an ornament base material 11 made of a resin material and a decorative film 12 attached according to the surface shape of the ornament base material 11 on the inside of the vehicle.

Both the light-emissive region 10a and the non-emissive region 1b have a laminated structure as shown in FIG. 5, and have a structure in which the decorative film 12 is attached to the surface of the ornament base material 11. On the surface of the ornament base material 11, a design layer 12a forming the decorative film 12 and an adhesive layer 12f applied to attach the light shielding layer 12c are formed.

The ornament base material 11 is a member corresponding to a transmissive body, and is formed as a gray resin molded product by adding a black pigment to a translucent white resin material. As the resin material of the ornament base material 11, acrylonitrile butadiene styrene resin (ABS), polycarbonate resin (PC), polymethyl methacrylate resin (PMMA), etc. can be used. As a material for the ornament base material 11, a material considered to be suitable may be selected in consideration of heat resistance, chemical resistance, impact resistance, combustion resistance, etc. In this embodiment, PC resin is used. ..

When the blending amount of the PC resin material forming the ornament base material 11 is 100, the blending ratio of the black pigment is preferably set to 1 or less. With the above configuration, the ornament base material 11 is formed as a resin molded product made of a gray color similar to black, and the light transmittance can be maintained relatively high to ensure the desired brightness of the light emitting region 10a.

As shown in FIG. 3, the ornamental base material 11 forming the light-emissible region 10a has a configuration in which a light source unit 30 is arranged outside the vehicle, and transmits light from the light source unit 30. The ornament base material 11 contains a light-scattering material, and light passing through the ornament base material 11 becomes diffused. As a result, when the lamp 31 included in the light source unit 30 is turned on, the light is transmitted while diffusing through the ornament base material 11 forming the light emitting region 10a, so that the entire light emitting region 10a can be made to emit light. A known light diffusing agent can be used as the light scattering material.

In the present embodiment, the ornament base material 11 forming the light emitting area 10a and the ornament base material 11 forming the non-light emitting area 1b are integrally molded, but the present invention is not limited to this, and the light emitting area 10a is not limited thereto. The ornament base material 11 forming the non-light emitting area 1b and the ornament base material 11 forming the non-light emitting area 1b may be individually molded.

The decorating film 12 is a member corresponding to a decorating body, is positioned on the innermost side of the vehicle in the ornament unit 10, and imparts the decorating property to the ornament unit 10. The decorative film 12 is composed of a colorless and transparent film base material made of PMMA resin or polyethylene terephthalate resin (PET), and a light-shielding layer 12c and a design layer 12a which are sequentially laminated by surface treatment. It is a film having a light property. That is, the decorative film 12 is a decorative laminated body that is exposed to the vehicle interior side of the ornament base material 11 and is capable of transmitting light that has passed through the ornament base material 11.

The design layer 12a that constitutes the decorative film 12 is a portion that imparts decorativeness to the ornament unit 10, and includes a metal layer 12b formed of a metal thin film formed by vacuum deposition processing, as shown in FIG. It has been configured. As a result, the vehicle interior surface side of the ornament unit 10 is colored so as to have a metallic texture.

The metal layer 12b constituting the design layer 12a is made of a metal thin film having a thickness of about 10 to 100 nm and has a light reflectance of about 90% and a light transmittance of about 10%. As a result, in the daytime, external light is reflected by the design layer 12a, so that the light emitting ornament 1 is decorated with the metallic design applied to the design layer 12a. In addition, at night, the light emitted from the light source unit 30 is transmitted through the ornament base material 11 and the decorative film 12 and can be seen through the metallic design of the design layer 12a, so that the light emitting ornament 1 can be used in the daytime. Will be decorated with an unusually illuminated design.

The design layer 12a will be described in detail, as shown in FIG. 5, as a metal layer 12b, a pattern portion 12g arranged on the metal layer 12b, and a coating layer forming a surface in order from the ornament base material 11 side. The top layer 12h is formed by stacking.

The pattern portion 12g is a layer provided with a pattern such as a grain pattern of about 1 to 10 μm and is formed by a printing process. Here, the picture includes a pattern such as wood grain, a pattern, and characters. The top layer 12h is a UV hard coat layer or a protective film, has a thickness of about 3 to 130 μm, and is formed for the purpose of increasing the film strength of the decorative film 12 and preventing scratches or peeling.

As shown in FIG. 5, the light-shielding layer 12c that constitutes the decorative film 12 is arranged in a light-shielding portion 12d that shields the light emitted from the light source unit 30 toward the inside of the vehicle, and in an area adjacent to the light-shielding portion 12d. , A portion that also has a transmitting portion 12e that transmits light.

The light shielding layer 12c is formed on the surface side of the ornament base material 11 by a printing process such as gravure printing. At this time, the light shielding layer 12c is formed by laminating at least two layers by a printing process, and suppresses the occurrence of pinholes.

The light-shielding portion 12d is a portion of the light-shielding layer 12c that corresponds to the non-light-emitting region 1b, and is formed by solid-printing a black ink on the surface side of the ornament base material 11 by a printing process. Or, it is colored in the same color as black.

A portion of the light-shielding portion 12d, which is solidly printed with black ink, does not have a light-transmitting property, and blocks light transmitted through the ornament base material 11. As a result, the non-light emitting region 1b does not emit light while the light emitting ornament 1 emits light.

The transmissive portion 12e is a portion of the light shielding layer 12c corresponding to the light emitting region 10a, and is formed such that the central portion is cut out in a substantially elliptical shape. In addition, in the configuration in which the transmissive portion 12e is transparent, the term “transparent” includes not only colorless and transparent but also translucent with a tint such as translucent slightly clouded.

Here, as shown in FIG. 5, at least a part of the pattern portion 12g is arranged on the light shielding portion 12d, and the end E of the pattern portion 12g is located at the boundary K between the light shielding portion 12d and the transmission portion 12e. It is placed on top. According to such a configuration, since the pattern portion 12g and the transmissive portion 12e are lined up neatly adjacent to each other, the end portion E of the pattern portion 12g becomes the boundary of the light emitting region 1a and the appearance is improved, and the pattern portion 12g is provided. Even in such a case, the decorative effect of light is properly exerted.

Further, the metal layer 12b is arranged on the light shielding layer 12c, the top layer 12h as a coating layer is provided on the metal layer 12b, and the pattern portion 12g is arranged on the metal layer 12b. With such a configuration, it is possible to form the pattern portion 12g with a small number of layers.

Further, in order to blur the boundary line between the light shielding portion 12d on the side where the pattern portion 12g is not provided and the light transmitting portion 12e, and to make the light emitted from the ornament unit 10 appear vague, the light transmitting portion 12e changes to the light shielding portion 12d. It is preferable that the gradation is provided so that the print density of the light-shielding portion 12d is gradation so that the print density becomes darker as the distance from the transmission portion 12e increases. By doing so, the boundary line between the light-shielding portion 12d and the transmissive portion 12e on the side where the pattern portion 12g is not provided can be hidden, and the texture of the light-emitting region of the light-emitting ornament 1 can be further enhanced, and the light-emitting illumination can be provided. It can be vague and improve the design.

In the above configuration, the light-shielding portion 12d of the decorative film 12 cannot transmit the light transmitted through the ornament base material 11, and the light transmitted through the ornament base material 11 is transmitted only by the transmission portion 12e. As a result, while the light emitting ornament 1 emits light, only the portion of the decorative film 12 where the transmissive portion 12e is located emits light. As a result, only a predetermined portion of the light emitting area 1a can be made to emit light, and the decorative effect brought about by the illumination effect of the light emitting ornament 1 is improved.

Further, the light from the light source unit 30 is transmitted through the ornament base material 11 containing the light-scattering material when the light is emitted toward the ornament unit 10. As a result, the irradiation range of the light emitted from the ornament unit 10 is widened, and compared with the case where the light-scattering material is not contained, while illuminating a wide range around the light-emitting ornament 1, its irradiation brightness is substantially within the irradiation range. It is uniform, and it is possible to achieve a good lighting effect.

As described above, in the present embodiment, the decorative film 12 is attached to the surface of the ornament base material 11 to form the decorative body on the surface of the ornament base material 11. However, the method for forming the decorative body on the surface of the ornament base material 11 is not limited to this, and for example, a vapor deposition process or mirror ink coating is directly applied to the resin surface of the ornament base material 11. May be. It is preferable to form the design layer 12a by attaching the decorative film 12 described above, in that the light transmitting portion 12e and the light shielding portion 12d can be freely arranged.

On the other hand, as shown in FIG. 4, a boss 13 and an engagement protrusion 14 for fixing the ornament unit 10 to the door base 4 are formed on the rear surface side of the ornament unit 10. The boss 13 is a portion that is fitted into a boss hole 4a formed at a corresponding position in the door base 4 and fixed with a screw in this state. The engagement protrusion 14 is a portion that fits into a fitting hole 4 b formed at a corresponding position in the door base 4 and snap-fits to the door base 4. The boss 13 and the engaging projection 14 correspond to the decorative unit side fixing portion, and extend from the surface of the ornament unit 10 on the vehicle outer side.

Further, the boss 13 and the engaging projection 14 are provided in the ornament unit 10 in a region excluding the light emitting region 10a, and are provided at both ends in the longitudinal direction of the ornament unit 10, as shown in FIG. Since the boss 13 and the engaging protrusion 14 are provided in the non-light emitting area 1b as described above, the ornament unit 10 can be attached and fixed to the door base 4 so as not to interfere with the irradiation of light from the light emitting area 10a. I can.

Further, as shown in FIG. 4, ribs 15 are provided upright on the vehicle exterior rear surface of the ornament unit 10. The rib 15 is provided to secure the rigidity of the ornament unit 10, extends from the back surface of the ornament unit 10, and is endless so as to form a substantially trapezoidal outline when the back surface of the ornament unit 10 is viewed from the front. Has been formed. The rib 15 surrounds the light source unit 30 when the light source unit 30 is assembled to the ornament unit 10. As a result, the light source unit 30 can be arranged more compactly in a limited space such as the inside of the vehicle door.

<Structure of light source unit 30>
The light source unit 30 constitutes the light emitting region 1 a of the light emitting ornament 1 together with the ornament base material 11 and the decorative film 12 constituting the light emitting region 10 a of the ornament unit 10. As shown in FIG. 6, the light source unit 30 has a lamp 31 and a light guide 32 having an emission surface 32a for emitting light from the lamp 31. The lamp 31 and the light guide 32 are held by a holder 33, and are integrated as a light source unit 30 via the holder 33.

The light source unit 30 is located on the back side of the light emitting area 10a of the ornament unit 10 and functions as an illuminating body that emits light toward the front of the light emitting area 10a. The lamp 31 is suitable as a light source for vehicle lighting, such as an LED lamp. The light guide 32 is a long light guide plate, and as shown in FIG. 6, the vertical width gradually increases from the front end to the rear end in the longitudinal direction.

Further, the light guide 32 is fitted into a holder 33, which is a frame formed to match the outer shape of the light guide 32, and is held by the holder 33. The holder 33 is preferably colored in white so as to favorably reflect the light emitted from the light guide plate, and is made of, for example, a material in which a white pigment is added to PC resin.

The lamp 31 is attached to the holder 33 at a position adjacent to the front end of the light guide 32. If the lamp 31 is mounted at a position adjacent to the front end of the light guide 32 in this way, the light traveling direction and the light guide direction by the light guide 32 coincide with each other, so that a good light guiding effect is obtained. You can In particular, in the present embodiment, of the both ends in the longitudinal direction of the light guide 32, the width of the front end on the side where the lamp 31 is attached is narrower than that of the rear end. That is, since the width of the light guide plate becomes wider toward the downstream side in the traveling direction of light, the light from the lamp 31 that spreads in a fan shape can be guided more appropriately. When the length of the light guide 32 in the longitudinal direction is relatively long, the lamps 31 may be attached to the sides of both ends of the light guide 32 in the longitudinal direction.

The light source unit 30 having the above configuration is assembled on the back surface side of the ornament unit 10 in a snap fit form.

<Modification>
In the above embodiment, the decorative component for vehicle according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit of the invention, and it goes without saying that the present invention includes equivalents thereof. Further, the materials, arrangement positions, shapes, and the like of the above-mentioned members are merely examples for achieving the effects of the present invention, and do not limit the present invention.

In the above-described embodiment, as shown in FIG. 5, the design layer 12a constituting the decorative film 12 includes, in order from the ornament base material 11 side, a metal layer 12b, a pattern portion 12g, and a top layer 12h as a coating layer. , And are laminated, but the arrangement and the configuration can be appropriately changed without being limited to this.

For example, like the decorative film 12X shown in FIG. 9, the end portion E of the design portion 12g of the design layer 12a may be arranged so as to overlap the transmission portion 12e. Even with such a configuration, since the pattern portion 12g and the transmissive portion 12e are lined up neatly adjacent to each other, the end portion E of the pattern portion 12g becomes the boundary of the light emitting region 1a, and the appearance is improved, and when the pattern portion 12g is provided. Even then, the decoration effect by light is appropriately exhibited.

At this time, it is preferable that the pattern portion 12g includes a second light shielding portion 12i, which is different from the light shielding portion 12d that is the first light shielding portion, on at least a part of the surface facing the light shielding layer 12c. At this time, it is more preferable that the pattern portion 12g is provided with the second light shielding portion 12i on the entire surface facing the light shielding layer 12c. According to such a configuration, even if the pattern portion 12g has a light-transmitting property, a difference in light and dark appears clearly, so that the appearance is improved.

In the decorative film 12X shown in FIG. 9, the area of the overlapping portion where the pattern portion 12g overlaps the transmissive portion 12e and the second light shielding portion 12i is such that the pattern portion 12g does not overlap the transmissive portion 12e and the second light shielding portion 12i. It is preferable that the area is smaller than the area of the overlapping portion. With such a configuration, light leakage from the pattern portion 12g is appropriately suppressed.

When the example shown in FIG. 5 and the example shown in FIG. 9 are combined, the end E of the pattern portion 12g is arranged on the boundary K between the light-shielding portion 12d and the transmissive portion 12e, or the end portion of the pattern portion 12g. E is arranged so as to overlap with the transmissive portion 12e. In other words, the end portion E of the pattern portion 12g may be arranged so as to coincide with the boundary K between the light shielding portion 12d and the transmission portion 12e or to be arranged beyond the boundary K. According to such a configuration, since the pattern portion and the transparent portion are lined up adjacently and neatly, the edge of the pattern portion becomes the boundary of the light emitting region to improve the appearance, and the pattern portion with the pattern formed is provided. Even in such a case, the decorative effect of light is properly exerted.

Further, as in the decorative film 12Y shown in FIG. 10, the position of the pattern portion 12g can be arranged on the top layer 12h as a coating layer. With such a configuration, the pattern portion 12g can be easily formed, and the pattern portion 12g can be additionally provided to the existing light emitting ornament. At this time, the clear coating 12j may be provided on the pattern portion 12g. Further, it is preferable to provide the black coating layer B corresponding to the light shielding portion 12d on the back surface side of the ornament base material 11.

Here, as shown in FIG. 10, it is preferable that the width h of the transmissive region in the black coating layer B is formed smaller than the width H of the transmissive portion 12e in the light shielding layer 12c (that is, h<H). .. With this configuration, the light emitted from the light source unit 30 toward the inside of the vehicle is narrowed down by the black coating layer B, so that diffusion of the light transmitted to the inside of the vehicle is suppressed.

Further, the shape and the like of the light emitting area 1a (light emitting area 10a) and the non-light emitting area 1b in the ornament unit 10 can be appropriately changed. For example, as in the ornament unit 10X shown in FIG. 11, the side edge of the light emitting area 1aX (light emitting area 10aX) is aligned with the side edge of the non-light emitting area 1bX, or the light emitting area 1aX (light emitting area 10aX) is changed. It is also possible to make the upper end portion coincide with the upper end portion of the non-light emitting area 1bX.

Further, the end portion E of the pattern portion 12g may be arranged so as to intersect with the boundary line formed by the boundary K between the light shielding portion 12d and the transmission portion 12e. According to such a configuration, the positional relationship between the end E of the pattern portion 12g and the boundary K between the light shielding portion 12d and the transmission portion 12e differs depending on the location, and it is possible to generate light shading.

In the above embodiment, the metal layer 12b forming the decorative film 12 is formed on the surface side of the ornament base material 11 by the vacuum vapor deposition process, but the present invention is not limited to this, and the vapor deposition process is not limited thereto. Besides, it may be formed by surface treatment such as printing treatment, painting treatment, plating treatment, or transfer treatment.

In the above embodiment, the light shielding layer 12c that constitutes the decorative film 12 is formed on the front surface side of the ornament base material 11 by a printing process such as gravure printing, but is not limited to this. In addition to the printing treatment, it may be formed by surface treatment such as painting treatment, vapor deposition treatment, plating treatment, or transfer treatment. However, when the light-shielding layer 12c is formed by gradation processing, it is advantageous to select a printing process capable of easily performing high-definition gradation processing, particularly a gravure printing process, and there is also a cost reduction effect.

In the above-described embodiment, the case where the surface light-emitting body including the lamp 31 and the light guide 32 is used as the illuminating body that radiates light toward the front of the light emitting region 1a has been described, but the present invention is not limited thereto. .. For example, a point light emitting body may be used as the irradiation body including only the lamp 31. Alternatively, instead of the lamp 31 and the light guide 32, an illuminator having an organic EL as a light source may be used.

In the above-described embodiment, the case used as the decorative component of the vehicle door lining R has been described, but the present invention is not limited to this, and can be applied to a roof lining, a door lining, a side lining, or the like. For example, it is possible to use a light emitting ornament as a decorative component for a seat back board that is attached to the back of a driver's seat or a passenger seat. In particular, for the light emitting ornament, a touch panel as an information display screen may be formed.

Further, the light emitting ornament may be used as a decorative component for a roof mounted on the left and right side portions of a vehicle or a roof pillar that supports the roof. In addition, the light emitting ornament may be used as a decorative part for the dashboard located in front of the driver's seat, or as a decorative member for its surroundings or a decorative part for a console box provided between seats. A light emitting ornament may be used.
