Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improved structure of a stud-shaped road signal device installed at the center of the ground surface of an intersection.

[Prior Art] A reflector and a light emitting diode are provided on the four side walls of a truncated pyramidal stud body, and a solar cell is placed on the top surface of the stud body, so that when the surrounding environment is bright, such as during the daytime, the solar cell is activated. Charge electricity to storage battery,
When the surrounding environment becomes dark at night, etc., it detects that the electromotive force of the solar cell has decreased, and a switching circuit is activated to blink the light emitting diode using the power from the storage battery that was charged during the day. A type road signal device is already known from Utility Model Publication No. 57-61137.

In order to attach the solar cell to the tack body, such conventional devices form a concave accommodating part on the upper center surface of the tack body, fit the solar cell directly into the accommodating part, and fill the gap with silicone resin to form an integral part. It is fixed with adhesive.

[Problems to be solved by the invention] The conventional device as described above has the following problems.

In other words, as the ground-mounted stud-type road signal device is installed at the center of the ground surface at an intersection as described above, there is a risk that an excessive load from a vehicle running over the solar cell may cause it to be crushed and damaged. There is. In such a case, it becomes necessary to replace the damaged solar cell, but in conventional devices, the solar cell is directly adhesively fixed to the stud body, so the silicone resin that is the adhesive is gradually dissolved to separate the solar cell. The replacement work was time-consuming.

[Means for Solving the Problems] Therefore, the present invention forms a concave accommodating part in the center of the stud main body, adhesively fixes the solar cell in the box frame-shaped saucer with silicone resin, etc. It is fitted and fixed in a removable manner by screwing into the housing part.

[Function] The solar cell is adhesively fixed in the saucer, and the saucer is fixed to the rivet main body by screws or other easy-to-attach/remove means, so when replacing the solar cell, the replacement work is simple by attaching and detaching the whole saucer. Can be done quickly.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings.The rivet main body 1, which is formed in the shape of a short square truncated pyramid, is made of aluminum die-casting, and has a square concave accommodating portion 2 in the center of its upper surface. It is formed. A concave groove 3 in the shape of a letter is provided in the center of the bottom surface of the accommodating part 2,
Further, two through holes 4, 4 are bored in the groove 3. On the other hand, rectangular window holes are formed on the four side walls of the stud body 1, and red reflectors 5a, 5 are formed therein.
a and yellow reflectors 5b, 5b are loaded. Further, high-brightness light emitting diodes 6a, 6a... that emit red light are installed in the reflectors 5a, 5a, and high-brightness light-emitting diodes 6b, 6b... that emit yellow light are installed in the reflectors 5b, 5b, respectively. A resin lens 7 is attached.

Reference numeral 8 denotes a box-frame-shaped saucer with an external shape that fits inside the accommodating portion 2 of the rivet main body 1, and is made of aluminum die-cast like the rivet main body 1, and has a concave groove of the rivet main body 1 in the center of its lower surface. A reinforcing rib 9 having a shape matching 3 is protruded, and two screw holes 10 are bored in the reinforcing rib 9 at positions matching the through holes 4 of the groove 3. . A solar cell 11 is installed in this saucer 8, and a gap 12 between it and the saucer 8 is filled with transparent silicone resin 13 and integrally fixed with adhesive. 14 and 15 are solar cells 1
This is a transparent glass plate with a square plane located on the upper and lower surfaces of 1 to protect it.

Then, the saucer 8 is fitted into the accommodating portion 2 of the rivet main body 1 with the concave groove 3 and the reinforcing rib 9 aligned, and the screw of the saucer 8 is inserted from the lower surface of the rivet main body 1 through the through holes 4, 4. Screws 16, 16 are inserted into the holes 10, 10 and tightened, thereby removably fixing the saucer 8 to the rivet main body 1. The gap between the saucer 8 and the stud body 1 is filled with silicone grease 24 to make it waterproof. If waterproofing means such as silicone grease 24 is not used, water droplets will accumulate in the gap between the saucer 8 and the rivet body, and in winter, this will freeze and expand, causing the screws 16, 16 and the housing There is a risk of damage to the inside of part 2. silicone grease 2
4 is used to prevent the above situation.

A cylindrical part 17 is integrally formed on the lower surface of the stud body 1, and a printed circuit board 18 forming a light/dark sensitive switching circuit and a sealed storage battery 19 such as a lead-shielded small battery are accommodated here. There is.
Reference numeral 20 denotes a substantially cubic container, which is buried underground with its top opening aligned with the ground surface. An O-ring 21 is mounted in a groove 23 on the upper opening edge of the container 20, and the O-ring 21 is hermetically pressed against the lower surface of the stud body 1. 22 is inserted into the four corners of the rivet main body 1 and screwed into screw holes formed in the four corners of the container 20, thereby attaching the rivet main body 1 to the container 20.
The figure shows a bolt that is removably fixed to the frame. The bolt 22 has a tapered surface that contacts the rivet body 1 to prevent it from loosening. Furthermore, by filling the container 20 with liquid silicone, even if rainwater enters from the outside, the printed circuit board 1
8 and storage battery 19 are protected.

Since the present invention is constructed as described above, when replacing the solar cell 11, the bolt 2 is first replaced.
2 to remove the rivet main body 1 from the container 20, and then remove the screws 16, 16 from the lower surface of the rivet main body 1, then the solar cell 11 can be removed together with the saucer 8. Then, another saucer 8 containing a new solar cell 11 is screwed to the rivet body 1, and then the rivet body 1
is fixed to the container 20 with bolts 22 and the solar cell 11
The exchange has been completed.

[Effects of the present invention] As described above, according to the present invention, the solar cell 11 is adhesively fixed to the saucer 8, and the saucer 8 is fixed to the rivet main body 1 by means of easy attachment and detachment such as screwing. The solar cells 11 can be replaced more easily and quickly than in the past, and the work can be completed in a short time at intersections with heavy traffic, so this work does not hinder the safety of workers and the flow of traffic. This contributes to the promotion of public interest, such as by saving time.

In addition, since the reinforcing ribs 9 are provided protrudingly on the lower surface of the saucer 8, the pressure resistance of the saucer 8 is increased, thereby making it possible to prevent damage to the solar cells 11 due to crushing.
