Description

{Floor traffic lights formed on pedestrian crossings}

The present invention relates to a floor traffic light formed in a crosswalk, and more particularly, the LED substrate is safely protected even if some water leakage occurs due to the multi-waterproof structure. It relates to a floor traffic light formed in a crosswalk in which the body sidewall is firmly supported while being pressed and pressed in a direction surrounding the outer circumferential surface of the support member, thereby increasing the maximum body load to a high degree.

In general, crosswalks are installed for pedestrians to cross the road on city roads or general roads where vehicles pass. Pedestrian traffic lights that repeatedly generate pedestrian signals and stop signals are installed in the crosswalk for the safety of pedestrians. Pedestrians are expected to safely wait on the sidewalk at the crosswalk.

Pedestrian traffic lights installed in conventional crosswalks simply tell pedestrians whether the signal of the crosswalk is a walking signal or a stop signal by color, so that the time necessary for crossing is not sufficiently secured or accidents occur due to late entry.

When pedestrians waiting at a pedestrian traffic light at a crosswalk have to wait safely within the safety line, many pedestrians unconsciously cross the crosswalk waiting line, the safety line, or even enter the roadway to wait for a pedestrian signal at a stop sign. There are many problems that can cause safety accidents.

Recently, there are many examples of braille sidewalk blocks for the visually impaired on pedestrian sidewalk lines in crosswalks.

The braille sidewalk block is a form in which a braille protrusion is formed on the upper surface of the block body, and recently, the braille protrusion is made to emit light at night so that not only the blind, but also general pedestrians, low vision and low vision people can sufficiently secure visibility, and pedestrians A number of light-emitting braille sidewalk blocks have been proposed to suppress trespassing.

In addition, by replacing the boundary stone installed at the boundary between the sidewalk and the road at the crosswalk with a light-emitting signal block that interlocks with the crosswalk traffic light, the crosswalk signal light can be used to recognize the crosswalk signal through the light emitted from the road and the sidewalk boundary. A number of techniques have been proposed.

On the other hand, in order to solve this problem, there are "Floor traffic lights for crosswalks" of Patent Application No. 10-2017-0149444 and "Floor traffic lights controlled in conjunction with crosswalk traffic lights" of Patent Application No. 10-2017-0161569. Since the conventional technology is a simple form in which an LED lighting substrate is installed on a block body, durability is greatly reduced, and thus it is difficult to apply in practice.

In addition, although it has to withstand a lot of rain in the rain, the light emitting signal for a crosswalk according to the prior art has a very weak waterproof property, and it is not possible to respond stably to a temperature change, so there is a problem in that it is easily broken.

The body 10, the support part 14, the support member 15, the cover 17, the inner cover so that the side wall is firmly supported while being pressed and pressed in the direction surrounding the outer circumferential surface of the support member so that the maximum bearing load of the body is highly increased. (100), the waterproof layer (200) is composed of a main configuration.

First, according to the present invention, a body 10 having a space 11 is formed through injection molding as shown in FIGS. 1 and 2 , and the body 10 is formed of a PC material transparent plastic.

Then, the support portion 14 for supporting the LED substrate 13 inserted into the body 10 so as to have an inclination of 10 to 15 degrees is formed.

At this time, the light of the LED lamp formed on the LED substrate 13 mounted on the support portion 14 that supports the inclination of 10 to 15 degrees increases as the light emitted to the outside increases as much as the inclination angle, so that it can be directly irradiated to the pedestrian.

Here, the light is not emitted to the driver on the side of the road, so that the view can be secured and the driver's eyesight can be protected from the light.

That is, as compared with a conventional LED lamp installed horizontally as in the prior art, the light emitted to the outside increases and the pedestrian can see it more efficiently.

On the other hand, a support member 15 fitted to the lower side of the body 10 is formed, and at this time, a cover 17 for sealing the space 16 of the support member 15 is formed.

The inner cover 100 has a lower compartment in which the assembly of the LED substrate 13 and the supporting part 14 is accommodated, and is formed in a reduced size compared to the lower part to form an upper compartment, and the upper compartment is bound to the upper plate of the body 10 . do. At this time, the transparent upper plate 110 is spaced apart from the bottom surface of the upper plate of the body 10 to form an air layer, so condensation is prevented. ) Even if cracks occur on the top plate, leakage is tightly blocked.

That is, the upper end of the inner cover 100 is inserted and installed into the slot groove 10d formed on the bottom surface of the upper plate of the body 10 . Accordingly, since the LED substrate 13 is precisely positioned in the center of the body 10 by the inner cover 100, the assembly is excellent, and in particular, the flow of the LED substrate 13 is prevented after construction.

In addition, the waterproof layer 200 according to the present invention is filled in the inner space of the body 10 except for the upper region of the LED substrate 13 to waterproof the LED substrate 13 . The waterproof layer 200 is formed of a waterproof coating layer containing epoxy, urethane, and silicone to seal the space between the lower portion of the LED substrate 13 and the inner peripheral surface of the body 10 and the outer peripheral surface of the inner cover 100 .

As it is provided, the maximum bearing load of the main body 10 is increased to a high degree, and in particular, damage caused by the sidewall splaying of the main body 10 is prevented.

In addition, a fitting groove (15b) is formed on the outer circumferential surface of the support member (15), and a fitting protrusion (10b) is formed on the inner circumferential surface of the side wall of the body 10 corresponding to the fitting groove (15b).

Accordingly, the inclined projection (10a) and the inclined groove (15a) are provided to be fitted in the horizontal direction by the fitting groove (15b) and the fitting projection (10b) in a state in which they are engaged at an inclination angle, and are engaged in a double binding structure, so that they are coupled in the longitudinal direction. The durability against the load applied in the lateral direction as well as the load applied in the lateral direction is improved.

In Fig. 4, the inclined protrusion 10a is spaced apart from the lower end of the side wall of the body 10, and a buffer space portion 10c is formed between the inclined protrusion 10a. The inclined protrusion 10a is brought into point contact with the inclined groove 15a by the buffer space portion 10c, so that the load caused by the pressing is distributed to prevent breakage and breakage.
