BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector mounted on a vehicle, particularly a large reflector mounted on a large cargo transportation vehicle such as a truck or a trailer.

[0002]

2. Description of the Related Art A reflector mounted on the back of a vehicle retroreflects the natural light during the daytime and the headlight of the following vehicle at nighttime in the same direction as the incident direction, so that the vehicle stops and parks ahead. Alternatively, a driver behind the vehicle is visually recognized that the vehicle is running, and attention is drawn to prevent a rear-end collision accident or the like. Therefore, there is a demand for a reflection performance that can be reliably viewed in any weather regardless of day or night. Also, in particular, large cargo transportation vehicles such as trucks and trailers (total vehicle weight 8
t or more than 5t of the maximum loading capacity), with the recent revision of security standards, it is mandatory to install a large reflector, and its shape, size, color, performance, etc. are specified. . Incidentally, the shape of the reflector is 1 on each side.
It is a rectangle of 30 mm or more, provided with a fluorescent part and a reflective part, and the areas of the fluorescent part and the reflective part are 400 mm ² and 80 mm, respectively.
0 mm ² or more, having the ability to confirm its fluorescence from a distance of 150 m behind in the daytime, the number is 4 or less, the color of the fluorescence is red, and the color of the reflected light is yellow It is prescribed.

FIGS. 5A and 5B are a front view and a sectional view taken along the line V--V of a conventional example of such a large reflector.
The reflector 1 is of a frame type, and a fluorescent portion 3 and a reflective portion 4 are provided on the surface of a reflective substrate 2 made of aluminum alloy or the like.
Is provided. The fluorescent portion 3 is formed by attaching a tape containing a fluorescent pigment to the peripheral edge of the surface of the reflective substrate 2. The reflection section 4 is formed by attaching a reflection tape to the inside of the fluorescent section 3, and constitutes a retroreflection section by reflecting external light in the incident direction. The reflector 1 configured as described above is fastened and fixed to a predetermined portion of the vehicle body 7 by a plurality of set screws (or bolts) 5.

Reference numeral 8 denotes a washer, 9 denotes a screw mounting hole through which the set screw 5 is inserted, and 10 denotes a tape escape portion provided around the screw mounting hole 9 on the front surface side of the reflective substrate 2. The escape portion 10 is provided to prevent a portion around the screw mounting hole 9 of the fluorescent portion 3 made of a soft tape from being damaged when the set screw 5 is tightened with a high-speed tool such as an impact driver at the time of attachment to the vehicle body 7. ing.

FIG. 6 shows another conventional example of a large reflector. This reflector 1 is called a chevron type (zebra type), and is a reflection substrate 2 made of an aluminum alloy or the like.
A reflective tape is adhered to the entire surface of the reflective member with an adhesive to form a reflective portion 4, and a fluorescent tape is adhered to the surface of the reflective portion 4 in a chevron pattern to provide a fluorescent portion 3.

[0006]

As described above, in the conventional reflector 1, when the set screw 5 is tightened at the time of attachment to the vehicle body, the fluorescent portion 3 in the case of the frame type and the reflecting portion 4 in the case of the chevron type are used. A part, especially the peripheral portion of the screw mounting hole 9 is easily damaged by the screw head, so the tape around the screw mounting hole 9 is cut out to provide a tape escape portion 10,
The underlying reflective substrate 2 is exposed. However, the formation of such a tape escape portion 10 requires trimming the fluorescent tape in accordance with the outer shape of the reflective substrate 2 or opening a hole corresponding to the screw mounting hole 9. There has been a problem that the number of working steps increases and the manufacturing cost increases. Further, as shown in FIG. 5 (c), when a wrap margin L is provided at the boundary with the reflective tape and affixed, there is a problem that a step is generated due to the tape thickness or wrinkles are generated to impair the appearance. Was. Furthermore, in the case of a chevron-type reflector shown in FIG. 6 or a reflector provided with a fluorescent portion 3 and a reflective portion 4 on the surface of a reflective substrate 2 having an irregular cross-sectional shape as shown in FIG. Since the number of steps is significantly increased, there is a problem that productivity is reduced.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and its purpose is to complicate the pattern of the fluorescent part and the reflective part or to make the sectional shape of the reflective substrate. It is an object of the present invention to provide a reflector which can be easily manufactured even if it is complicated, and which can prevent the appearance from being deteriorated even when the lap portion is provided by overlapping the edges of the fluorescent portion and the reflective portion. .

[0008]

In order to achieve the above object, according to the present invention, a fluorescent portion and a reflective portion are formed on a surface of a reflective substrate, and the fluorescent portion is formed by applying a fluorescent paint.
The reflection part is formed by sticking a reflection tape.

[0009]

In the present invention, the fluorescent portion is formed by applying a fluorescent paint, thereby eliminating the need for trimming the tape and forming the tape escape portion. Since the thickness of the end portion of the fluorescent coating material is reduced by somebody, when a reflecting portion is formed by overlapping a reflecting tape on the end portion, the step portion is inconspicuous.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 is a front view of the reflector according to the present invention,
FIG. 2 is an enlarged sectional view of a main part of the reflector. In the drawings, the same components as those of the conventional device shown in FIGS. 5 to 7 are denoted by the same reference numerals. In these figures, in this embodiment, a fluorescent paint is applied to the peripheral edge of the surface of a reflective substrate 2 formed in a plate shape by using an aluminum alloy or the like.
Further, a frame-shaped reflector 20 is manufactured by forming a reflection portion 4 by attaching a reflection tape to the inside of the fluorescent portion 3, that is, a central portion of the surface of the reflection substrate 2. A set screw (not shown) inserted into the mounting hole 9 is screwed into a screw hole 21 of the vehicle body 7 to fix the reflector 20 to the vehicle body 7. The fluorescent portion 3 can be easily formed by applying a fluorescent paint by a conventionally known silk printing method or the like.

In such a reflector 20, since the fluorescent portion 3 is formed by applying a fluorescent paint, unlike the case of a fluorescent tape, the tape is trimmed or an opening is formed at a position corresponding to the tape escape portion 10. It is suitable for manufacturing a reflector having a complicated fluorescent portion or a reflective substrate having a complicated cross-sectional shape, and can be manufactured at low cost. Also, as shown in FIG. 3, even when the reflecting portion 4 is overlapped with the fluorescent portion 3, the edge of the fluorescent portion 3 made of the fluorescent paint is dropped and the thickness is reduced.
A sharp step hardly occurs, and the appearance is not impaired.

FIG. 4 shows another embodiment of the present invention.
(A) is an example in which a white paint is applied to the surface of the reflective substrate 2 to form the reflective layer 24, and a fluorescent paint is applied thereon to form the fluorescent portion 3, and (b) is an edge of the reflective tape. The part is overlapped with the fluorescent part 3 and adhered to form the reflective part 4,
This is an example in which the surfaces of the fluorescent section 3 and the reflecting section 4 are covered and protected by a transparent film 25. The other configuration is the same as the above embodiment.

In such a configuration, the same effect as in the above embodiment can be obtained. In particular, the fluorescent part 3 and the reflecting part 4
In the reflector whose surface is covered and protected by the transparent film 25, there is no possibility that the fluorescent part 3 and the reflective part 4 are damaged, stained, or the reflective part 4 is peeled off.
There is an advantage that durability can be improved.

[0014]

As described above, in the reflector according to the present invention, the fluorescent portion is formed by applying a fluorescent paint on the surface of the reflective substrate, so that the work of trimming and attaching the fluorescent tape is unnecessary. It is suitable for manufacturing a reflector having a complicated fluorescent portion or a reflective substrate having a complicated cross-sectional shape, and can reduce the manufacturing cost. In addition, since the coating generally has a reduced thickness due to the peripheral portion dropping off, when a reflective portion is formed by overlapping reflective tapes, a sharp step does not occur, and the appearance is impaired as in the past. There is nothing.
