Description

  The present invention relates to a decorative structure that allows a symbol member such as an emblem attached to the front or back of an automobile body to be lifted by light emitted from an LED lamp.

  Conventionally, as this type of decorative structure, a plate-like or film-like light guide part with one end face attached to the vehicle side is the back side, and a plate-like or film located on the other end face side of the light guide part A vehicular light-emitting display device having a display portion superimposed in the thickness direction with a emblem of the shape as a surface side is disclosed (for example, see Patent Document 1). In this vehicular light emitting display device, light entering the display unit from the light source on the vehicle side is prevented from being transmitted to the surface in the thickness direction by the light shielding layer formed on the display unit so as to cover the other end surface of the light guide unit. And leaks in the direction crossing the thickness direction from the peripheral portion through the light guide portion, and is configured to illuminate the emblem from the peripheral side. Further, when the display unit is viewed from the thickness direction surface side, the outer peripheral edge of the light guide unit is formed in substantially the same shape along the outer peripheral edge of the emblem, or as the outer peripheral edge part of the light guide unit goes outward. A chamfered portion is formed so as to approach the vehicle side.

In the light emitting display device for a vehicle configured as described above, the emblem appears light and floats in the air by illuminating the emblem from the peripheral side with light leaking from the peripheral portion of the light guide portion. It is possible to display an unprecedented new image and to improve the image of the manufacturer, vehicle type, model, and the like. Further, when the display portion is viewed from the thickness direction surface side, if the outer peripheral edge of the light guide portion is formed in substantially the same shape along the outer peripheral edge of the emblem, the light leaking from the outer peripheral edge portion of the light guide portion is outside the emblem. The periphery can be illuminated almost evenly, making it easier to reach the viewer. Further, if a chamfered portion is formed on the outer peripheral edge of the light guide portion so as to approach the vehicle side toward the outside, the light passing through the light guide portion is viewed from the chamfered portion as well as the direction orthogonal to the thickness direction. It is easy to leak in an oblique direction toward the top so that the visibility of the emblem can be improved.

  However, in the light emitting display device for a vehicle shown in the above-mentioned conventional Patent Document 1, since the light source is provided inside the vehicle away from the light guide unit, a space for accommodating the light source must be provided inside the vehicle. In addition, there is a problem that the number of processing steps on the vehicle side increases. Moreover, in the vehicle light-emitting display device disclosed in the above-described conventional Patent Document 1, since the optical axis of the light source and the longitudinal direction of the light guide are substantially orthogonal, the light emitted from the light source reflects the reflecting surface of the light guide. In this case, since the light reaches the periphery of the light guide part after being reflected a great number of times, there is a problem that the amount of light leaking outside from the periphery of the light guide part is considerably reduced.

  The first object of the present invention is not to provide a storage space for the main LED lamp and the sub LED lamp on the mounted member side, and requires only a small number of processing steps on the mounted member side. An object of the present invention is to provide a decorative structure that can improve the function of illumination of a symbol member when a lamp is turned on. The second object of the present invention is to direct the light emitted from the main LED lamp or the sub LED lamp directly to the main irregular reflection surface or the sub irregular reflection surface, so that the light emitted from the main LED lamp or the sub LED lamp hardly attenuates. An object of the present invention is to provide a decorative structure that can reach a diffuse reflection surface and a sub-diffuse reflection surface and can brighten these reflection surfaces. A third object of the present invention is to provide a decorative structure that can secure high brightness of the main irregular reflection surface by providing a cover portion of the main irregular reflection surface without cleaning the main irregular reflection surface that is uneven and difficult to clean. To provide a body.

  In the invention according to claim 1, as shown in FIGS. 1 to 3, the symbol mark 12 is formed by an opaque plate material and attached to the attached member 11, and both surfaces are smooth by a transparent or translucent plastic. A base member 13 which is plate-shaped and formed in a shape corresponding to the symbol member 12 and interposed between the mounted member 11 and the symbol member 12, and reaches the peripheral portion of the base member 13 through the inside of the base member 13. A decorative structure including one or more main LED lamps 14 that emit light 14a, a main housing portion 13d that houses the main LED lamp 14 is formed in the base member 13, and the light reaching the peripheral portion. A main irregular reflection surface 13f for irregularly reflecting 14a is formed on the peripheral edge. In the decorative structure described in claim 1, when the main LED lamp 14 is turned on at night, the light 14 a emitted from the main LED lamp 14 directly reaches the main random reflection surface 13 f through the inside of the base member 13. Compared with the conventional one, the main irregular reflection surface 13f can be made to shine brighter. Thereby, the function as illumination of the symbol member 12 can be improved.

  The invention according to claim 2 is the invention according to claim 1, and further, as shown in FIGS. 1 to 3, the peripheral portion of the base member 13 is perpendicular to the vertical line erected on the attached member 11. The base member 13 has a main irregular reflection surface 13f inclined at an angle α in the range of 0 to 60 degrees, and irregularities for irregularly reflecting the light 14a are formed on the main irregular reflection surface 13f. In the decorative structure described in claim 2, when the main LED lamp 14 is turned on at night, the light 14a emitted from the main LED lamp 14 directly hits the main irregular reflection surface 13f and is irregularly reflected by the main irregular reflection surface 13f. Since the base member 13 comes out of the base member from the symbol member 12 side, the main irregular reflection surface 13f shines brighter than the conventional member, and the symbol member 12 can be lifted more clearly.

  The invention according to claim 3 is the invention according to claim 1, and further, as shown in FIGS. 4 to 6, the peripheral portion of the base member 53 is perpendicular to the vertical line erected on the attached member 11. The main irregular reflection surface 53f is inclined at an angle β in the range of 30 to 60 degrees on the side opposite to the base member 53 side, and the main irregular reflection surface 53f is formed with irregularities for irregularly reflecting the light 14a. Features. In the decorative structure described in claim 3, when the main LED lamp 14 is turned on at night, the light 14a emitted from the main LED lamp 14 directly hits the main irregular reflection surface 53f and is irregularly reflected by the main irregular reflection surface 53f. Since it comes out of the base member from the symbol member 12 side of the base member 53, the main irregular reflection surface 53f shines brighter than the conventional member, and the symbol member 12 can be lifted more clearly.

  The invention according to claim 4 is the invention according to claim 3, and further, as shown in FIGS. 4 to 6, the peripheral edge portion of the base member 53 is added to the main random reflection surface 53 f and the main random reflection surface 53 f. It has the cover part 53g which extends toward the to-be-attached member 11 from the protruding end, and has a tip closely attached to the to-be-attached member 11. In the decorative structure described in claim 4, since the main irregular reflection surface 53f is shielded from the outside air by the cover portion 53g and the mounted member 11, dust hardly accumulates on the main irregular reflection surface 53f, and has irregularities and is cleaned. Even if it is difficult to clean the main irregular reflection surface 53f, it is possible to ensure high luminance of the main irregular reflection surface 53f.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, and further, as shown in FIGS. 7 and 8, a punched portion in which characters, symbols, or figures are punched into the symbol member 82. 82d is formed, and an auxiliary member 85 is formed between the symbol member 82 and the base member 53. The auxiliary member 85 is formed of a transparent or translucent plastic and has a flat plate shape corresponding to the symbol member 82. A sub-accommodating portion 85d that accommodates the sub-LED lamp 84 is formed on the member 85, and the emitted light 84a passes through the inside of the auxiliary member 85 and directly reaches the surface of the auxiliary member that faces the punching portion 82d. Is arranged, and a secondary irregular reflection surface 85d for irregularly reflecting the light 84a is formed on the surface facing the punched portion 82d. In the decorative structure described in claim 5, when the main LED lamp 14 and the sub LED lamp 84 are turned on at night, the light emitted from the main LED lamp 14 passes directly through the base member 53 and directly onto the main irregular reflection surface. Therefore, the main irregular reflection surface can be brightly illuminated, and the light 84a emitted from the sub LED lamp 84 passes through the auxiliary member 85 and directly reaches the secondary irregular reflection surface 85d. Therefore, the secondary irregular reflection surface 85d is brightly illuminated. be able to. Thereby, the function of the symbol member 82 as illumination can be further improved.

  According to the present invention, since the base member is interposed between the mounted member and the symbol member, and the main housing portion for housing the main LED lamp is formed in the base member, when the main LED lamp is turned on at night, Light passes directly through the inside of the base member and directly reaches the main diffused reflection surface formed on the peripheral edge of the base member. As a result, since the main irregular reflection surface can be made to shine brighter than the conventional one, the function of the symbol member as an illumination can be improved. In addition, a space for accommodating a light source must be provided inside the vehicle, and in comparison with a conventional vehicle light emitting display device in which the number of processing steps on the vehicle side is increased, in the present invention, the main LED is provided on the mounted member side. There is no need to provide a storage space for the lamp and the sub LED lamp, and the number of processing steps to be performed on the mounted member side is very small. As a result, in the present invention, it is possible to reduce the number of processing steps for the mounted member and the number of steps for assembling the decorative structure to the mounted member.

  In addition, the peripheral edge of the base member has a main irregular reflection surface inclined at an angle α in the range of 0 degrees to 60 degrees on the base member side with respect to a vertical line standing on the mounted member. If irregularities for irregularly reflecting light are formed on the base member, the light emitted from the main LED lamp directly hits the main irregular reflection surface and diffusely reflects, and then comes out of the base member from the symbol member side of the base member. The symbol member can be clearly lifted. Further, the peripheral edge of the base member has a main random reflection surface that is inclined at an angle β in a range of 30 degrees to 60 degrees on the opposite side to the base member side with respect to a vertical line erected on the attached member. By forming irregularities for irregularly reflecting light on the main irregular reflection surface, the light emitted from the main LED lamp directly hits the main irregular reflection surface and diffusely reflects and then exits from the symbol member side of the base member to the outside of the base member. Can shine brighter, and the symbol member can be raised more clearly. Further, if the peripheral edge portion of the base member has a cover portion that extends from the projecting end of the main irregular reflection surface toward the attached member in addition to the main irregular reflection surface, the main irregular reflection surface is covered with the cover portion. In addition, since it is shielded from the outside air by the attached member, it is possible to ensure high brightness of the main irregular reflection surface without cleaning the main irregular reflection surface which is difficult to deposit dust on the main irregular reflection surface and is difficult to clean.

  Further, an auxiliary member is interposed between the symbol member having the punched portion and the base member, and the sub LED lamp emits light passing through the auxiliary member, and the sub housing portion that accommodates the sub LED lamp serves as the auxiliary member. When the main LED lamp and the sub LED lamp are turned on at night by forming a side irregular reflection surface that diffusely reflects light on the surface facing the punched portion of the auxiliary member, the light emitted from the main LED lamp is mainly diffusely reflected. As the light directly reaches the surface, the light emitted from the sub LED lamp also reaches the sub diffuse reflection surface directly. As a result, the main irregular reflection surface and the sub irregular reflection surface can be brightly illuminated, and the function of the symbol member as an illumination can be further improved.

Next, the best mode for carrying out the present invention will be described with reference to the drawings.
<First Embodiment>
As shown in FIGS. 1 to 3, the decorative structure 10 includes a symbol member 12 attached to the attached member 11, a base member 13 interposed between the attached member 11 and the symbol member 12, and a base member 13. And a main LED lamp 14 that emits light 14 a that reaches the peripheral edge of the base member 13. In this embodiment, the mounted member 11 is a front panel of an automobile, and the symbol member 12 is an emblem of an automobile manufacturer. The emblem 12 is formed with a symbol mark of an automobile manufacturer by a plate material such as an opaque ABS resin, polypropylene resin, polycarbonate resin, polyphenylene oxide (PPO) resin or the like. Specifically, the emblem 12 is formed in a disk shape, and has a pair of substantially semicircular holes 12a and 12a on the inner upper and lower portions. In other words, the emblem 12 has the bar portion 12c extending at a constant width in the lateral direction at the center of the ring portion 12b having a constant width. The base member 13 is formed of a transparent or translucent plastic, such as an acrylic resin, a polycarbonate resin, or a PPO resin, and has a flat plate shape on both sides. The base member 13 has a shape corresponding to the emblem 12, and includes a pair of holes 13a and a ring portion 13b. And a bar portion 13c. Since acrylic resin has high transparency, it is suitable for the base member 13. Further, both surfaces of the base member 13 are formed in a mirror shape. Specifically, the surface roughness (Ra) of both surfaces of the base member 13 is set to 10 μm or less, preferably 1 μm or less. Here, the surface roughness of both surfaces of the base member 13 is limited to 10 μm or less because the light 14 a of the main LED lamp 14 emitted from the inside of the base member 13 is reflected on both surfaces of the base member 13. This is to prevent the both sides from coming out to the outside. In addition, both surfaces of the base member may be formed in a mirror shape, and a plate of ABS resin or the like subjected to opaque plating may be laminated on both surfaces of the base member, or opaque plating may be performed on both surfaces of the base member. . As a result, the light 14a emitted from the main LED lamp does not come out to the outside from both sides of the base member.

  As the main LED lamp 14, a lamp having a rated current of 10 mA to 500 mA, preferably about 20 mA having a relatively small luminance and a small amount of heat generation is used. For this reason, a limiting resistor (not shown) having a resistance value as small as 500Ω to 1.5 kΩ can be used. The main LED lamp 14 is fixed to the circuit board 17 via the lead wires 16 by soldering. The main LED lamp 14 is arranged so that light directly reaches a main irregular reflection surface formed at a peripheral portion of a base member described later. Here, “direct light reaches” means not only a phenomenon in which light is directly applied to the peripheral portion of the base member but also a phenomenon in which light directed to the peripheral portion is reflected on both surfaces of the base member and reaches the peripheral portion. Including. In other words, it is arranged so that the optical axis of the main LED lamp 14 faces the peripheral edge of the base member. In this embodiment, six main LED lamps 14 are used, and two circuit boards 17 are used. Three main LED lamps 14 and one limiting resistor are fixed to one circuit board 17 by soldering. Each circuit board 17 is connected to an electrical wiring 18 for supplying power from the main LED lamp 14. Further, the base member 13 is formed with a pair of main housing portions 13d and 13d having a substantially semicircular shape in plan view near the intersection of the ring portion 13b and the bar portion 13c. In these main housing parts 13d and 13d, circuit boards 17 each having three main LED lamps 14 and one limiting resistor fixed by soldering are housed one by one, and a cap 19 is adhered. . Two of the three main LED lamps 14 are soldered to the circuit board 17 so as to face the circumferential direction of the ring portion 13b of the base member 13, and the remaining one is in the longitudinal direction of the bar portion 13c of the base member 13. Soldered to the circuit board 17 so as to face outward. That is, the three main LED lamps 14 are provided so as to emit light toward different peripheral portions of the base member. The remaining one of the main LED lamps is not soldered to the circuit board so as to face the longitudinal direction outside of the bar portion of the base member, but on the longitudinal direction inside (longitudinal center side) of the bar portion of the base member. You may solder to a circuit board so that it may face. Further, the number of main LED lamps 14 fixed to one circuit board is not limited to three, and may be one, two, or four or more. The cap 19 is formed with a through hole 19a in which the one-way filter 21 is mounted and a through hole 19b through which the electric wiring 18 passes. The one-way filter 21 can prevent pressure fluctuation in the main housing portion 13d and can prevent intrusion of water, steam, dust and the like. Further, after the electric wiring 18 is inserted into the through hole 19b of the cap 19, the inside of the main housing portion 13d is sealed and the electric wiring 18 is fixed by closing the through hole 19b with the hot melt adhesive 22. . The circuit board 17 in the main housing portion 13d is fixed by being sandwiched between a rib 13e protruding from the base member 13 and a rib 19c protruding from the cap 19.

  On the peripheral edge of the base member 13, that is, on the outer peripheral edge and inner peripheral edge of the ring portion 13 b of the base member 13, and both side edges of the bar portion 13 c of the base member 13, stand at points corresponding to the both end edges of the front panel 11. A main irregular reflection surface 13f is formed on the base member 13 side with respect to the provided vertical line and is inclined at an angle α in the range of 0 to 60 degrees, preferably 40 to 50 degrees. On the main irregular reflection surface 13f, fine irregularities for irregularly reflecting the light 14a emitted from the main LED lamp 14 are formed. The unevenness on the main irregular reflection surface 13f is directly sandblasted on the reflection surface, sandblasted on the mold for molding the base member 13, or rough filed with coarse No. 0 to No. 2 medium. Or it forms by apply | coating the coating material (For example, the transparent coating material which disperse | distributed the glass particle) to diffusely reflect. The surface roughness (Ra) of the main irregular reflection surface 13f is set in the range of 20 to 100 μm, preferably 40 to 60 μm. Here, the reason why the angle of the main irregular reflection surface 13f is limited to 60 degrees or less on the base member 13 side with respect to the vertical line erected on the front panel 11 is that when the angle exceeds 60 degrees, the base member is exposed from the emblem. There is too much trouble. The reason why the surface roughness of the main irregular reflection surface 13f is limited to the above range is to effectively diffusely reflect the light 14a emitted from the main LED lamp 14.

  The operation of the decorative structure 10 configured as described above will be described. When the main LED lamp 14 is turned on at night, the light 14a emitted from the main LED lamp 14 passes through the base member 13, and most of the light directly reaches the main irregular reflection surface 13f. A part of the light is reflected by both smooth surfaces of the base member 13 and reaches the main random reflection surface 13f. Then, after the light 14a that has reached the main irregular reflection surface 13f is irregularly reflected by the main irregular reflection surface 13f and then exits from the emblem 12 side of the base member 13 to the outside of the base member, the main irregular reflection surface 13f shines brighter than the conventional one. The emblem 12 can be raised more clearly. As a result, the function of the emblem 12 as illumination can be improved.

<Second Embodiment>
4 to 6 show a second embodiment of the present invention. 4 to 6, the same reference numerals as those in FIGS. 1 to 3 denote the same components. In this embodiment, the base member 53 is fitted into a dish-shaped recess formed in the front panel 11. At the peripheral edge of the base member 53, 30 is provided on the opposite side to the base member 53 side with respect to a vertical line erected at a point corresponding to the edge of the base member of the front panel 11 (excluding a cover portion described later). A main irregular reflection surface 53f is formed which is inclined at an angle β in the range of 60 ° to 60 °, preferably 40 ° to 50 °. On the main irregular reflection surface 53f, fine irregularities for irregularly reflecting the light 14a emitted from the main LED lamp 14 are formed as in the first embodiment. Since the formation method and surface roughness of the main irregular reflection surface 53f are the same as the formation method and the surface roughness of the main irregular reflection surface 13f in the first embodiment, repeated description is omitted. In addition to the main irregular reflection surface 53 f, a cover portion 53 g extending from the projecting end of the main irregular reflection surface 53 f toward the front panel 11 and having a tip closely attached to the front panel 11 is formed on the periphery of the base member 53. It is formed integrally. The outer surface 53h of the cover portion 53g is inclined at an angle γ in the range of 0 degrees to 30 degrees, preferably 0 degrees to 5 degrees toward the base member 53 with respect to a vertical line erected on the outer peripheral edge thereof. The outer surface 53h faces an inclined surface 11a that creates a recess in the front panel 11. The configuration other than the above is the same as that of the first embodiment.

  In the decorative structure 50 configured as described above, when the main LED lamp 14 is turned on at night, most of the light 14a emitted from the main LED lamp 14 directly hits the main irregular reflection surface 53f and is irregularly reflected by the main irregular reflection surface 53f. After that, since it comes out of the base member on the emblem 12 side of the base member 53, the main irregular reflection surface 53f shines brighter, and the emblem 12 can be lifted more clearly. Further, since the main irregular reflection surface 53f is shielded from the outside air by the cover portion 53g and the front panel 11, dust hardly accumulates on the main irregular reflection surface 53f. As a result, high brightness can be ensured when the light 14a is irregularly reflected by the main irregular reflection surface 53f without cleaning the main irregular reflection surface 53f that has fine irregularities and is difficult to clean. A part of the light 14a emitted from the main LED lamp 14 passes through the cover portion 53g and is emitted in the horizontal direction from the outer surface 53h. The emitted light 14a is reflected by the inclined surface 11a of the front panel 11 and travels straight in a direction away from the front panel. The front panel 11 at the periphery of the emblem can be lifted by the light 14a. Since the operation other than the above is substantially the same as the operation of the first embodiment, repeated description will be omitted.

<Third Embodiment>
7 and 8 show a third embodiment of the present invention. 7 and 8, the same reference numerals as those in FIGS. 4 to 6 denote the same components. In this embodiment, a punched portion 82 d in which characters are punched is formed in the emblem 82, and an auxiliary member 85 is interposed between the emblem 82 and the base member 53. In this embodiment, the punched portion 82d is a letter XYZ formed by punching the bar portion 12c of the emblem 82. The auxiliary member 85 is formed in substantially the same manner as the base member 53. That is, the auxiliary member 85 has a flat plate shape on both sides made of transparent or translucent plastic such as acrylic resin, polycarbonate resin, PPO resin, etc., and is formed in a shape corresponding to the emblem 82, and has a pair of holes 85a and a ring. It has a portion 85b and a bar portion 85c. Since acrylic resin has high transparency, it is suitable for the auxiliary member 85. However, the peripheral portion of the auxiliary member 85 is preferably formed as a mirror surface or a diffusely reflecting surface that stands up with respect to the front panel 11, and the auxiliary diffused surface 85d that diffusely reflects the light 84a on the surface facing the punched portion 82d of the auxiliary member 85. Is formed. On the auxiliary irregular reflection surface 85d, fine irregularities for irregularly reflecting light 84a emitted from an auxiliary LED lamp 84 described later are formed. Since the method of forming irregularities and the surface roughness on the auxiliary irregular reflection surface 85d are the same as the method of forming the main irregular reflection surface 13f in the first embodiment and the surface roughness, repeated description will be omitted. By providing irregularities on the auxiliary irregular reflection surface 85d, the light 84a emitted from the auxiliary LED lamp 84 can be effectively irregularly reflected.

  The auxiliary member 85 is formed with a sub-accommodating portion 85e that accommodates the sub-LED lamp 84. The sub-accommodating portion 85e is formed in a shape corresponding to the pair of main accommodating portions 13d and 13d formed in the base member 53, and is formed in two so as to communicate with the pair of main accommodating portions 13d and 13d, respectively. . In the main housing portion 13d and the sub housing portion 85e that communicate with each other, there is a single circuit board 17 on which two main LED lamps 14, one sub LED lamp 84, and one limiting resistor are soldered. The cap 19 is bonded to the sub-accommodating portion 85e while being accommodated. The circuit board 17 is fixed by being sandwiched between a rib 13e protruding from the base member 53 and a rib 85f protruding from the auxiliary member 85. One sub-LED lamp 84 is soldered to the circuit board 17 via the lead wire 16 so as to be accommodated in the sub-accommodating portion 85e and directed inward in the longitudinal direction (longitudinal direction center side) of the bar portion 85c of the auxiliary member 85. The two main LED lamps 14 are soldered to the circuit board 17 via the lead wires 16 so as to be accommodated in the main accommodating portion 13d and directed in the circumferential direction of the ring portion 85b of the auxiliary member 85 (FIG. 4). reference). As a result, the light 14 a emitted from the main LED lamp 14 passes through the base member 53, and the light 84 a emitted from the sub LED lamp 84 passes through the auxiliary member 85. The configuration other than the above is the same as that of the second embodiment.

  In the decorative structure 80 configured as described above, when the main LED lamp 14 and the sub LED lamp 84 are turned on at night, the light 14a emitted from the main LED lamp 14 passes through the base member 53 to the main random reflection surface 53f. At this time, the main member 53 comes out of the base member 53 from the emblem 82 side of the base member 53, so that the main irregular reflection surface 53f can be brightly illuminated (see FIG. 4). On the other hand, since the light 84a emitted from the sub LED lamp 84 passes through the auxiliary member 85 and directly reaches the sub diffuse reflection surface 85d and comes out of the base member from the emblem 82 side of the base member 53, the sub diffuse reflection surface 85d is brightened. Can shine. As a result, the main irregular reflection surface 53f shines brightly (see FIG. 4), whereby the emblem 82 can be clearly lifted, and the auxiliary irregular reflection surface 85d shines brightly, whereby the punched portion 82d formed on the emblem 82 Since the characters can be clearly raised, the function of the emblem 82 as illumination can be further improved. Here, by changing the color of the light 14a emitted from the main LED lamp 14 and the color of the light 84a emitted from the sub LED lamp 84, the function of the emblem 82 as an illumination can be further improved. Since the operation other than the above is substantially the same as the operation of the second embodiment, repeated description will be omitted.

  In the second embodiment, the example in which the main LED lamp is housed in the base member as in the first embodiment has been described. However, the main irregular reflection surface 53f and the cover portion 53g shown in FIG. 4 are provided. By using the base member, the main LED lamp can be provided on the attached member side as in the prior art. In the first to third embodiments, the emblem of an automobile manufacturer is cited as the symbol member. However, the emblem of a vehicle operating company such as a truck, bus, train, airplane, or ship, the emblem of an industrial machine manufacturer, It may be an emblem or insignia of a national or local government. In the first to third embodiments, the front panel of the vehicle is used as the attached member. However, a rear panel, hatchback, trunk lid, front grill, or the like of the vehicle may be used. Further, in the third embodiment, the punched portion in which the characters XYZ are punched is formed in the emblem, but a punched portion in which characters other than XYZ, symbols, or figures are punched may be formed.
