DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character-type license plate, and more particularly, to a license plate using an EL luminous body so as to emit a number or the like.

[0002]

2. Description of the Related Art Generally, a number plate is a metal plate on which predetermined characters (including numbers) are written. The number plate is attached to the front and rear portions of a vehicle, and at the same time, it is mounted on a vehicle at night. It is illuminated by a number light.

In order to improve the visibility at night,
As shown in FIGS. 6 and 7, a character 3 is punched out of a character 3 having a predetermined ground color and a transparent synthetic resin plate is formed on the character 3 on an open / close frame 2 attached to the entire surface of the flat case 1. While fixing the attached license plate 4,
There are also cases in which an illuminating lamp 5 is provided inside the case 1, and a luminous license plate in which characters on the license plate 4 are illuminated by the illuminating lamp 5 at night or the like is also known.

As a light source of such a license plate, a light bulb is currently used. However, such a light bulb has a drawback that the character 3 cannot be uniformly illuminated unless a light dispersion plate or the like is used. E that emits light on the surface
A character-type license plate using an L illuminant has also been developed (Japanese Utility Model Laid-Open No. 58-41642, Japanese Utility Model Publication 7-5).
No. 2766). As shown in FIG. 8, the EL luminous body 6 includes a luminous body 61 formed of a transparent waterproof resin sheet 62.
The electrode terminal 63 for connecting to an AC power supply extends from the luminous body 61 and projects from the cover of the resin sheet 62.
The conducting wire 7 is connected to the electrode terminal 63, and the conducting wire 7 is configured to be connected to the DC / AC converter 8.

However, the light-emitting license plate of an automobile must exhibit light-emitting properties even under severe weather conditions such as typhoons and thunderstorms, and under conditions where vibrations are constantly applied. It is assumed that a short circuit or a luminous body itself is destroyed. Therefore, although a sealing material or the like is provided on the upper end surface of the case 1 to prevent water, dust, and the like from entering the case 1, it cannot be completely prevented. In this case, it is assumed that when water or the like enters the EL luminous body 6, it enters from the end of the resin sheet 62.

[0006] Further, the EL luminous body 6 as described above maintains luminescence for more than 10000 hours, but it is inevitable that the luminous time elapses or that the EL luminous body 6 is replaced due to some kind of situation. However, conventionally, such exchangeability as described above is not considered at all, and it is not practical at present.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and in a character-type license plate using an EL luminous body, it is possible to prevent water from entering from the end of the luminous body and to provide a character with excellent exchangeability. It is intended to provide an optical license plate.

[0008]

Means for Solving the Problems To solve the above-mentioned problems, a character-type license plate according to the present invention is provided with an opening / closing frame attached to the entire surface of a case, which is colored in a prescribed ground color and has a character. In a character-type license plate in which a portion is punched out and a character plate is fixed with a license plate plate on which a transparent synthetic resin plate is adhered, and an EL luminous body is provided inside the case to make the character portion shine.
The EL luminous body is supported by a support member that covers at least an end thereof, and the support member is detachably supported on an upper part of a case.

According to the present invention, since the end of the EL luminous body is covered with the support member, water does not enter the luminous body from the end, and the inside of the case, not the bottom of the case, It was supported in a suspended state. Since water or the like entering the case tends to flow along the inner surface or the bottom surface of the case, supporting the device in a suspended state makes it difficult for water or the like to come into contact with the EL luminous body surface, thereby improving durability. Further, since the frame is supported by the support member and the frame is placed on the upper part (for example, a flange) of the case, there is an advantage that the frame can be easily replaced simply by opening the opening / closing frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a light-emitting license plate according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the light-emitting license plate according to the present invention when an open / close frame is opened. Shows a sectional view of a main part.

As is apparent from these figures, the character-type license plate according to the present invention is provided with an opening / closing frame 2 attached to the entire surface of a flat case 1 and is colored with a prescribed ground color, and punches out three characters. A number plate 4 having a transparent synthetic resin plate adhered to the character 3 is fixed (see FIGS. 5 to 7), and an EL luminous body 6 is provided inside the case 1.
Is provided. The EL luminous body 6 has a structure in which a luminous body 61 is covered with a transparent waterproof resin sheet 62, and an electrode terminal 63 for connecting to an AC power source extends from the luminous body, and the resin sheet It has a structure that protrudes from the cover. A conductor 7 is connected to the electrode terminal, and the conductor 7 is configured to be detachably connected to a DC / AC converter 8 via a watertight outlet C.

In the present invention, as shown in FIGS. 1 and 2, the EL luminous body 6 is supported by a support member 9.
In this embodiment, the support member 9 is shown in FIGS.
As shown in the figure, in a shape corresponding to the shape of the EL luminous body 6,
The lower member 91 is formed in a frame shape so that the surface of the EL luminous body 6 is exposed, and an upper member 92 having a similar shape and having a flange 921 projecting in the circumferential direction. The EL luminous body 6 is sandwiched between the upper member 92 and fixed. That is, as shown in FIG. 4, in this embodiment, the EL luminous body 6 is attached to the lower member 91 and the upper member 92.
The grooves 911 and 922 are formed so as to support the ends of the EL element 6. The ends of the EL luminous body 6 are sandwiched and fixed to the grooves 911 and 922 by the adhesive 10. By bonding and fixing with the adhesive 10 in this manner, the upper member 92 and the lower member 91 are integrated, and the end of the EL luminous body 6 is covered with the adhesive. Water can be prevented from entering from the part. When the resin sheet 62 of the EL luminous body 6 is sandwiched between the bonded portions as in this embodiment, the groove is not necessarily formed because the portion is a thin portion. However, in the case where the EL light emitting body 61 is sandwiched, the groove as described above is more firmly formed.
It is clear that the L light-emitting body 6 can be supported, and water and the like hardly enter.

The electrode terminal 63 connected to the conductive wire 7 of the EL luminous body 6 is inserted into a through hole 93 formed by a groove formed in the upper member 92 and the lower member 91.
So that the conducting wire 7 comes out of the support member 9 (see FIG. 5). Also in this case, the adhesive 10
As a result, the insertion hole 93 is in a filled state, and water or the like does not enter from this portion. The conductor 7 is provided with a watertight outlet C at an end thereof, and the watertight outlet C is detachably connected to a converter 8. The watertight outlet C may be further housed in a commonly used watertight container.

On the other hand, a flange 11 is formed at the peripheral end of the case 1 over the entire circumference.
The sealing material 1 which is also elastic over substantially the entire circumference
2 are formed. When the opening and closing frame 2 is closed, the sealing material 12 comes into contact with the convex portion 41 of the license plate 4 attached to the opening and closing frame, and acts so as to prevent water or the like from entering the case 1. Has become.

As described above, the upper member 92 is formed with the flange 921 protruding all around in the circumferential direction. This flange 921 protrudes in the circumferential direction from the upper end of the upper member. The EL luminous body 6 supported by the support member 9 is supported by placing the flange 921 on the flange 11 of the case 1. For this reason, the EL luminous body 6 is provided in the case 1 in a so-called suspended state. Further, the flange 921 is provided so as not to be in contact with the sealing material 12, and even when water invades beyond the sealing material 12, most of the water is removed from the wall surface of the case 1 or the flange 11. It moves downward along.

According to the above-described embodiment, the supporting member is frame-shaped, but it is apparent that the supporting member may be shaped so as to cover a gap in the frame of the upper member and the lower member. In this case, it is clear that at least a portion of the upper member that covers the inside of the frame in the above embodiment is preferably transparent.

As described above, according to the present invention, the EL luminous body 6
Is supported by the upper member 92 and the lower member 91, and the EL luminous body 6 can be supported in a suspended state in the case 1. The risk of exposure is reduced, and the end of the EL luminous body 6 is sandwiched between the upper member and the lower member 91 and integrated with the adhesive 10, so that water from the end, Infiltration of salt and the like can be prevented. Further, when the EL luminous body 6 is transported as a part or stored, there is no possibility that the EL luminous body 6 is bent, and when the EL luminous body 6 is replaced, the converter 8 and the EL luminous body 6 are connected as described above. Since the connection is made by the watertight outlet C, the EL illuminator 6
In case of failure, it can be easily replaced simply by removing the outlet C, which is extremely practical. Further, even when vibration is applied, there is also an advantage that vibration is absorptive due to the suspended state.

[0018]

As described above, according to the light-emitting license plate of the present invention, since the end of the EL luminous body is covered with the support member, water does not enter the luminous body from the end. In addition, instead of being supported on the bottom surface of the case, it is supported in the case so as to be suspended in the air. Since water or the like entering the case tends to flow along the inner surface or the bottom surface of the case, supporting the device in a suspended state makes it difficult for water or the like to come into contact with the EL luminous body surface, thereby improving durability. Further, since the frame is supported by the support member and the frame is placed on the upper part (for example, a flange) of the case, there is an advantage that the frame can be easily replaced simply by opening the opening / closing frame.
