Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a road sign equipped with a light emitting device such as a light emitting diode.

[Prior Art] Conventionally, road signs have been put into practical use in which light emitting diodes are arranged on the display surface of the sign and are made to blink to attract the attention of drivers and the like. To explain its specific structure in detail using a stop sign as an example, first, an aluminum strip is bent into an inverted triangular shape, and a front plate and a back plate are fixed to each opening of the aluminum strip to form a box. A mold casing is formed, the word "stop" is displayed on the top plate, a light emitting diode is arranged around the periphery of the top plate, a storage battery for causing the light emitting diode to emit light is housed in the casing, and each light emitting diode is placed in the casing. They are connected using internal wiring.

[Problems to be solved by the invention] According to the above-mentioned conventional technology, the entire casing is made into a box-shaped casing in order to accommodate the storage battery, the wiring for the light emitting diode, etc. inside the casing, so there is a problem that the overall weight becomes heavy. be. For this reason, the pillars that support it are required to be sturdy, and therefore, when converting a conventionally common plate-shaped road sign to a road sign equipped with the above-mentioned light emitting device, it is necessary to replace the entire pillar. This was an obstacle to the spread of road signs equipped with the device.

[Means for Solving the Problems] Therefore, in the present invention, a holder frame 2 having a U-shaped cross section is fixed to the periphery of the back side of a sign board 1 on which a road sign is displayed, and the sign board is attached to the holder frame 2. A plurality of through holes 3, 3... are bored through one surface, and
Light emitting diodes 4, 4... are placed in these through holes 3, 3...
is inserted and fixed so that its light emitting part 5 protrudes from the surface of the sign board 1, and wiring 6 is provided inside the holder frame 2 to connect each light emitting diode 4, 4..., and the holder frame 2 is A cover plate 8 is fitted into the opening 7 to enclose the light emitting diodes 4, 4... and wiring 6 within the holder frame 2, and a storage battery 9 for causing the light emitting diodes 4, 4... to emit light. A road sign equipped with a light emitting device is constructed by fixing a box 11 containing a solar cell 10 for charging a storage battery to the back surface of a sign board 1.

[Function] Since the holder frame 2 on the back side of the sign board 1 acts as a reinforcing frame, the strength of the plate-shaped sign board 1 is increased.

Inside the holder frame 2 are light emitting diodes 4, 4...
On the other hand, since the storage battery 9 and the solar cell 10 for charging the storage battery are housed in a separate box 11, the box-shaped casing conventionally used to house them becomes unnecessary.

[Example] An embodiment of the present invention will be described below.

The sign board 1 is formed from an aluminum plate shaped into an inverted triangle, which is the shape of a temporary stop regulation sign, and has the word "stop" displayed on its surface. and,
To increase the strength of the sign board itself, the periphery is bent slightly backwards and squeezed.

The holder frame 2 is made of aluminum and has vertical walls 2b, 2b on both sides of a back plate 2a.
are erected to form a U-shaped cross section as a whole.
This holder frame 2 is attached by arranging three pieces in an inverted triangular shape on the periphery of the back surface of the sign plate 1 and fixing the back plate 2a. The back plate 2a of the holder frame 2 is provided with a plurality of through holes 3, 3, . The light emitting diode 4 is inserted into the through holes 3, 3, . On the other hand, a push nut 12 is disposed in the holder frame 2 to face the through holes 3, 3, . 4 is fixed. The light emitting diodes 4, 4, . Furthermore, the opening 7 of the holder frame 2
The light emitting diodes 4, 4, . . . and the wiring 6 are enclosed within the holder frame 2 by fitting a cover plate 8 having a generally torii-shaped cross section.

Next, the storage battery 9 is connected to the solar cell 1 for charging the storage battery.
The box 11 that accommodates 0 will be explained.

As shown in FIG. 4, the box 11 is constructed into a box shape by combining two members: a U-shaped base frame 11a and a U-shaped lid frame 11b. The base frame 11a is fixed to the back surface of the sign board 1 so as to be in contact with the vertical wall 2b of the holder frame 2 located on the upper side, and a through hole 14 communicating with the holder frame 2 is bored in the lower wall 11c in contact with the holder frame 2. The wiring 6 connecting the light emitting diodes 4, 4, . The storage battery 9
is attached to the base frame 11a by a substantially C-shaped holder 15.The lower end key part 17 of the holder 15 is engaged with the horizontal groove 16 of the base frame 11a, and the holder 1 is attached to the base frame 11a.
The body of the storage battery 9 is held by the arc-shaped portion 15' of the battery 9,
Furthermore, screw the upper end of the holder 15 with screws 18, 18.
It is fixed with.

Further, a solar cell 10 for charging the storage battery 9 is installed on the upper wall 11b of the base frame 11a. The solar cell 10 has a light-receiving surface 10' that is similar to the sign plate 1.
It is designed to protrude from the top surface and is connected to the storage battery 9 and a sensor circuit (not shown). When it is bright during the day, the electromotive force of the solar cell 10 is charged to the storage battery 9, and when it is dark at night, the sensor circuit detects that the electromotive force of the solar cell 10 has decreased, and the switching circuit is activated during the daytime. The light-emitting diodes 4, 4, . . . are made to blink using the electric power of the storage battery 9 that has been charged.

Note that 11e is a circuit box installed next to the storage battery 10, in which the blinking circuit and the sensor circuit are sealed with silicone resin to make it waterproof.

On the other hand, the lid frame 11b of the box 11 is
It is fitted so as to surround the upper surface and both side surfaces of the base frame 11a, and is attached to the base frame 11a with screws 19, 19, . . . . Therefore, when the storage battery 9 has reached the end of its service life or has malfunctioned, it can be easily replaced by removing the lid frame 11b of the box 11 and removing the holder 15.

The three mounting members 20, 20, 20 horizontally fixed to the back surface of the signboard 1 are used to attach the signboard 1 to a post erected on the road. The head of the bolt is fitted into the groove 21, and a column fastening fitting having a planar substantially Ω shape is screwed onto the bolt to connect it to the column.

[Effect of the invention] As explained above, according to the invention, the sign board 1
The holder frame 2 fixed to the back side acts as a reinforcing frame, and also accommodates the light emitting diodes 4, 4... and wiring 6 inside the holder frame 2.
Since the storage battery 9 and the solar cell 10 are housed in the box 11, the casing that conventionally housed them is no longer necessary, making it possible to reduce the overall weight to about 2/3 of the conventional product, while maintaining sufficient strength. drooping Therefore, it is possible to replace conventional road signs without replacing the support.
Replacement work time and costs can be reduced. Furthermore, since the storage battery 9 is housed in the box 11, the storage battery 9 can be easily replaced, and maintenance after installation is thereby facilitated, resulting in highly practical effects.
