Description

횡단보도 설치용 LED 도로표지병{LED road signs for crosswalks}LED road signs for crosswalk installation {LED road signs for crosswalks}

본 발명은 횡단보도 설치용 LED 도로표지병에 관한 것으로서, 더욱 구체적으로는 횡단보도를 따라 양쪽에 일정간격을 두고 바닥에 설치되어 주야간의 횡단보도를 보행하는 보행자 식별이 용이하도록 면발광을 이용하여 사고 발생을 줄이도록 하며, 구조적으로는 커버 내부에 충격을 완화하고 빗물의 유입을 차단하여 파손이나 고장을 방지하는 기술에 관한 것이다.The present invention relates to an LED road signpost for crosswalk installation, and more specifically, it is installed on the floor at regular intervals on both sides along the crosswalk to facilitate identification of pedestrians walking on the crosswalk day and night by using surface light emission to cause accidents. It relates to a technology that reduces damage and prevents damage or failure by structurally mitigating impact on the inside of the cover and blocking the inflow of rainwater.

횡단보도[橫斷步道]는 일반적으로 차도에 설치되는 것으로서, 사람이 차도를 가로질러 다닐 수 있도록 도로를 횡단하는 형태로 설치된 길을 의미한다. 이러한 횡단보도는 차량과 보행자가 인식할 수 있도록 비행기 활주로와 같은 줄무늬 형태로 길을 표시하게 되어 있다.A crosswalk [橫斷步道] is generally installed on a roadway, and means a road installed in the form of crossing a road so that people can cross the roadway. These crosswalks are designed to mark the road in the same striped form as an airplane runway so that vehicles and pedestrians can recognize them.

그러나 야간에는 차량운전자가 이러한 횡단보도를 식별하기 어려운 문제점이 있었다. 따라서, 주야간에 횡단보도 식별을 위해 횡단보도를 따라 일정간격으로 도로표지병이 설치되고 있다.However, there is a problem in that it is difficult for vehicle drivers to identify such crosswalks at night. Therefore, road signs are installed at regular intervals along the crosswalk to identify crosswalks day and night.

지금까지의 도로표지병은 반사경이 부착되어 차량의 빛을 반사하는 형태로 운전자에게 표시되고 있지만, 차량 헤드라이트에서 주사되는 빛을 이용하여 반사하는 빛의 가시거리가 짧기 때문에 운전자가 멀리서 횡단보도를 식별하지 못하는 문제점이 있고, 차량 운전자의 높이, 차량의 헤드라이트 위치 및 조사각 등 다양한 변수로 인해 운전자마다 식별력의 차이가 발생하는 등의 문제점이 있었다.Until now, road signs are indicated to the driver in the form of reflecting the light of the vehicle with a reflector attached. There is a problem in that a difference in discrimination occurs for each driver due to various variables such as the height of the vehicle driver, the position of the headlights of the vehicle, and the irradiation angle.

이러한 문제점을 해결하기 위해 도로표지병에 LED를 설치하여 자체적으로 빛을 발광하여 식별력을 높이는 기술들이 개시되어 있으나, LED발광을 위해서 도로표지병의 구조가 복잡해지고 전자부품이 삽입되기 때문에, 각종 고장이 발생하고 빗물의 유입이나 습기유입에 의해 고장이 발생하는 문제점이 있다. 또한 차량이 도로표지병의 위를 지나면서 지속적으로 하중을 주기 때문에, 외부충격에 의해 커버가 파손되는 등의 문제가 있었다.In order to solve this problem, technologies to enhance identification by installing LEDs on road signs to emit light themselves have been disclosed. And there is a problem that failure occurs due to the inflow of rainwater or moisture inflow. In addition, since the vehicle passes over the road marker and continuously applies a load, there is a problem in that the cover is damaged due to external impact.

The sealing member 300 is applied with a rubber material having elasticity to have a buffering effect and a sealing effect for blocking gaps.

또한 밀폐부재(300)는 투명커버(400)가 위에서 누르는 힘으로 조명설치틀(200)을 강하게 누르는 기능을 갖기 때문에, 조명설치틀(200)이 흔들리지 않고 밀폐부재(300)에 의해 고정되는 구조가 된다.In addition, since the sealing member 300 has a function of strongly pressing the lighting installation frame 200 with the force that the transparent cover 400 presses from above, the structure in which the lighting installation frame 200 is fixed by the sealing member 300 without shaking. becomes

그리고 본 발명의 투명커버(400)는 투명한 재질로 적용되어 조명설치틀(200)의 불빛이 투명커버(400)를 통해 나올 수 있도록 하고, 본체(100)의 개방된 윗부분을 막아주는 기능을 갖는다. 상기 투명커버(400)의 재질은 외부의 충격으로부터 쉽게 파손되지 않도록 강화유리 또는 강화플라스틱으로 적용되는 것이 바람직하며, 도면에 도시한 바와 같이 충분한 두께로 형성되는 것이 바람직하다.In addition, the transparent cover 400 of the present invention is applied with a transparent material so that the light of the lighting installation frame 200 can come out through the transparent cover 400 and has a function of blocking the open upper part of the main body 100. . The material of the transparent cover 400 is preferably made of tempered glass or reinforced plastic so as not to be easily damaged from external impact, and is preferably formed to a sufficient thickness as shown in the drawing.

또한 상기 투명커버(400)의 테두리에는 도 5에 도시한 바와 같이 가압단턱(410)이 돌출형성되어, 상기 가압단턱(410)의 상부를 고정링(500)이 누르는 형태로 결합되어 투명커버(400)의 이탈을 방지하는 구조가 되어 있다. 그리고 상기 투명커버(400)의 가압단턱(410) 끝부분은 본체(100) 및 고정링(500)의 안쪽면과 접촉되어 있지 않고 간극(S)이 형성되도록 결합되어 있다. In addition, as shown in FIG. 5, a pressing step 410 is protruded from the edge of the transparent cover 400, and the upper part of the pressing step 410 is coupled in a form in which a fixing ring 500 presses the transparent cover ( 400) is structured to prevent separation. And the end of the pressing step 410 of the transparent cover 400 is not in contact with the inner surface of the main body 100 and the fixing ring 500 and is coupled to form a gap (S).

상기 간극(S)이 형성됨에 따라 투명커버(400)가 변형될 수 있는 공간이 확보되면서 투명커버(400)의 파손을 방지할 수 있는 구조가 된다. 좀 더 자세히 설명하면 투명커버(400)의 상부에서 강한중량이 작용하게 될 경우, 투명커버(400)의 테두리가 외측으로 벌어지게 된다. 이 과정에서 간극이 형성되어 있지 않다면 벌어지는 힘에 의해 투명커버(400)가 파손될 수 있다. 따라서, 간극(S)에 의해 투명커버(400)가 벌어지더라도 파손되는 것을 방지할 수 있는 것이다.As the gap S is formed, a space in which the transparent cover 400 can be deformed is secured and a structure capable of preventing damage to the transparent cover 400 is secured. In more detail, when a strong weight is applied from the top of the transparent cover 400, the edge of the transparent cover 400 spreads outward. If the gap is not formed in this process, the transparent cover 400 may be damaged by the opening force. Therefore, even if the transparent cover 400 is opened by the gap (S), it is possible to prevent damage.
