Description

Floor traffic light

The present invention relates to a floor traffic light that is installed on the floor of a sidewalk or crosswalk adjacent to a crosswalk and operates in conjunction with a traffic light, so that pedestrians crossing the crosswalk can easily recognize the walking signal.

In general, crosswalks allow vehicles to safely cross roads, and are usually installed at road intersections or other places where there are many people crossing the road.

Crosswalk traffic lights are usually installed at crosswalks to periodically display stop signals and crossing signals, and these crosswalk traffic lights are installed at a certain height from the floor through supports.

The crosswalk traffic light is installed at the pedestrian's eye level, but the signal can only be seen by raising the head, so pedestrians who use their cell phones with their heads down cannot see the signal.

Accordingly, many technologies have been proposed for floor traffic lights that are controlled in conjunction with crosswalk traffic lights on sidewalks near crosswalks or on the floor within crosswalks.

As prior art related to the floor traffic light, a floor-embedded traffic light is disclosed in Korean Patent Publication No. 10-2009-0085239 (2009.08.07).

The patent describes a process in which white paint is applied to a crosswalk at regular intervals, a groove with a certain width is formed on the floor between the white paint and the white paint, and a plurality of red LED lamps and blue LEDs are arranged in a row at the bottom of the groove. An LED lamp device equipped with a lamp is installed embedded in the floor, and the red LED lamp and blue LED lamp of the LED lamp device blink sequentially according to the pedestrian crossing signal, thereby forming a floor-embedded traffic light.

In addition, Republic of Korea Patent Publication No. 10-2126461 (LED floor traffic light) includes a watertight packing in the case to block moisture from entering the inside, and an expansion member inside the case to dissipate heat through movement of air. The floor traffic light is activated.

In addition, Republic of Korea Patent Publication No. 10-1798404 (light-emitting sidewalk block) includes a support body that supports the LED lighting board inside the block body, a finishing base is installed to seal the bottom of the block body, and the inside of the block body. A light emitting sidewalk block composed of a structure in which an epoxy layer is filled between the lower part and an LED lighting board is disclosed.

However, all conventional technologies, including the above patents, did not have a perfect waterproof structure, so moisture easily entered the inside of the case after construction, causing failure of the LED module as well as the control panel due to moisture. As a result, frequent failures occurred after construction. It is difficult to maintain, and even if you want to replace it, you have to dig up the entire area around the installation location of the floor traffic light, which leads to an increase in replacement time as well as an increase in replacement cost.

In particular, as the installation space for floor traffic lights is small, it is not possible to provide enough wires during initial construction, and as they are installed embedded in concrete or cement, there is a problem in that it is not easy to replace one or part of several floor traffic lights. .

In fact, due to the various problems described above, most of the time, the space where several floor traffic lights are buried is dug up and then all of the floor traffic lights, not just some, are replaced.

Registered Patent Publication No. 10-2317117 (2021.10.19. Waterproof LED floor traffic light) Registered Patent Publication No. 10-2126461 (2020.06.18. LED floor traffic light) Registered Patent Publication No. 2249343 (2021.04.30. Floor traffic lights formed at crosswalks)

The present invention was created to solve the above-mentioned problems, and aims to provide a floor traffic light that completely blocks the penetration of moisture by improving waterproofness and prevents malfunction of the LED and lighting board due to moisture.

The solution of the present invention to solve the above problem is to form an accommodating space inside with the lower part open, and cut a certain length at the lower end on both walls in the longitudinal direction to form a wire passing hole (11). , a case 10 in which a binding piece 12 is formed at the edge of the wire passing hole 11 to protrude into the internal receiving space; A partition wall (25) is formed at a certain distance apart from the inner surface of the edge part of the case (10), and a waterproof space (20) is formed between the inner surface of the edge part of the case (10) and the partition wall (25); A partition wall (30) that connects the inner side of the edge portion of the case (10) and the partition wall (25) to partition the waterproof space (20) and reinforces the side surface of the case (10); A lighting board 40 installed in the internal accommodation space of the case 10 and having a plurality of red LEDs and green LEDs arranged on the upper surface; It is inserted into the opened lower part of the case 10 and both ends are bound to the binding piece 12, and a wire drawing hole 52 is formed on the surface for drawing out a wire connected to the lighting board 40, and the wire A wire storage unit 50 having a cross-section formed in a '∩' shape with a wire receiving groove 53 provided therein to accommodate the wire drawn out through the draw-out hole 52 and exposed to the outside; It is composed of a molding material 60 that is filled in the internal accommodation space of the case 10 and molds the lighting board 40 to block it from being exposed to the outside and prevents moisture from penetrating.

It is preferable that one side of the partition wall 30 connected to the partition wall 25 is cut by a certain length from the end to form a separation space 35 between the partition wall 25 and the partition wall 25.

Here, on one side of the sidewalk or on one side of the road surface, a traffic light insertion space is formed by cutting to a width and depth that allows the floor traffic light to be inserted and bound, and is inserted into the inside of the traffic light insertion space to be bound or seated on the floor. It is preferable to install a traffic light mounting member 70 formed of a tube with an open upper side with a cross section of '∪' or a plate with a cross section of '-'.

Hereinafter, a floor signal light according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

As shown, the floor traffic light according to the present invention is formed at the bottom of the waiting line of the crosswalk or the edge of the crosswalk line on the road side to provide additional walking signal information to pedestrians, and is a separate traffic signal installed on one side of the crosswalk. It is connected to a controller (not shown) with a power line and operates by receiving power through the power line and receiving walking signal information.

The floor traffic light of the present invention consists of a case 10, a waterproof space 20, a partition wall 30, a lighting board 40, a wire storage part 50, and a molding material 60.

The case 10 is molded from a transparent resin material and is formed as a rectangular cylinder with an open lower part and an accommodating space formed therein. On both walls in the longitudinal direction of the case 10, wire passing holes 11 are formed by cutting a certain length at the lower end through which wires pass, and at the edge of the wire passing holes 11, a binding piece protrudes into the internal receiving space. (12) is formed.

The wire passing hole 11 is sufficient as long as the wire can pass through it. For example, it can be formed by cutting the hole 11 to have a width and length of approximately 20 mm.

The upper surface of the case 10 is formed to be convexly curved. The upper surface of the case is formed to be convexly curved, which increases the bearing capacity and effectively responds not only to vertical loads but also to loads applied in a diagonal direction, thereby significantly reducing the possibility of damage.

Additionally, a plurality of reinforcing ribs 15 are formed on the upper inner surface of the case 10 in the width direction. By forming the reinforcing ribs 15, the bearing capacity is further increased, thereby improving the strength of the housing and preventing damage due to vertical or diagonal loads.

When the reinforcing ribs 15 are formed, the LEDs (red LEDs, green LEDs) arranged on the upper surface of the lighting board 40 are arranged to be located between the reinforcing ribs 15, so that when light is emitted from the LEDs, It is desirable to pass through the case so that it can be effectively investigated externally.

Additionally, anti-slip protrusions 13 may be formed on the upper surface of the case 10 at set intervals to prevent slipping.

The waterproof space 20 is formed at the edge of the case 10, and a partition wall 25 is formed at a certain distance from the inner side of the edge of the case 10, thereby forming a space within the edge of the case 10. It is formed between the side and the partition wall (25).

Since the case 10 is molded with the molding material 60, moisture penetration is basically impossible. However, even if the case 10 is molded with the molding material 60, the materials of the molding material 60 and the case 10 are As they differ, moisture penetrates through the gaps between them.

The lighting board is corroded by the infiltrated moisture, causing failure.

In the present invention, a waterproof space 20 is formed at the edge of the case 10, so that even if moisture penetrates through the gap between the molding material 60 and the case 10, it stays in the waterproof space 20, so that the infiltrated moisture is illuminated. It blocks movement to the substrate.

Here, when the waterproof space 20 is formed by the partition wall 25, the reinforcing force of the case 10 may be lowered due to the waterproof space. To solve this problem, the partition wall 30 is formed in the waterproof space 20. The partition wall 30 connects the inner side of the edge of the case 10 and the partition wall 25 to divide the waterproof space 20 into a plurality of spaces and reinforces the side of the case 10. .

The lighting board 40 is installed in the internal accommodation space of the case 10, and has a plurality of red LEDs and green LEDs arranged on the upper surface, and a heat sink is installed on the back of the lighting board 40 for effective heat dissipation. It can be.

At this time, the lighting board 40 may be installed tilted in one direction in the internal accommodation space of the case 10.

A control unit (not shown) connected to a traffic signal controller is installed below the lighting board 40 to control its operation by supplying power to the lighting board.

The wire storage unit 50 of the present invention is provided on the inner lower side of the case 10, and is installed so that both ends are fastened to the binding piece 12 by being inserted into the opened lower part of the case 10.
Reference numeral 51 denotes a binding groove formed on both ends of the wire storage unit 50 so as to be inserted into and fastened to the binding piece 12.

A wire withdrawal hole 52 is formed on the surface of the wire storage unit 50 for drawing out wires connected to the lighting board 40, and the cross-section is '∩' shaped so that a wire receiving groove 53 is formed inside. It is formed by

Since the wire receiving groove 53 is formed, the length of the wire connected to the lighting board 40 is made sufficiently long, and the extra wire exposed to the outside through the wire withdrawal hole 52 is placed in the wire receiving groove. It can be stored in (53), and as extra wires are stored, if replacement is required in the future due to damage to the case or malfunction of the lighting board, only the floor signal light in question is separated from the sidewalk floor, the wires are cut, and the new floor is installed. It can be easily replaced by connecting a traffic light.

In other words, conventionally, each floor traffic light is constructed so that it is connected to each other with no spare wire, making it difficult to lift just one floor traffic light from its installation position, and also, the wire is buried in asphalt or concrete with no spare wire. As a result, replacement work was quite difficult as the wires had to be exposed by digging all around and underneath the floor traffic light. However, in the case of the present invention, the extra wires are accommodated in the wire receiving groove and are not in contact with asphalt or concrete. There is an advantage in that replacement work can be done easily by being provided in good condition.

The molding material 60 is filled in the internal accommodation space and the waterproof space 20 of the case 10 to mold the lighting board 40 and isolate it from the outside, thereby preventing moisture infiltration and preventing malfunctions due to moisture. This is a configuration for

In the present invention, as the molding material 60 fills the inner space of the case 10 and the waterproof space 20, the inflow of moisture is primarily prevented to increase waterproofness, and moisture is prevented from entering through the gap between the molding material and the case. Even if it penetrates, the waterproof space is provided to secondarily block the movement of moisture into the internal space of the case 10 where the lighting board is provided.

Meanwhile, in the present invention, even if moisture penetrates into the waterproof space, it is basically blocked from moving to the partition wall, but the partition wall 30 to reinforce the case 10 is formed on the outermost edge of the case 10 and the partition wall. As (25) is connected, there is a possibility that moisture may move to the partition wall (25) through the tip of the partition wall (30).

In order to prevent moisture penetrating through the tip of the partition wall 30 from moving to the partition wall 25, one side of the partition wall 30 connected to the partition wall 25 is cut by a certain length from the end. It is preferable that a separation space 35 is formed between the partition wall 25 and the partition wall 25.

Due to the formation of the separation space 35, even if there is moisture moving along the tip of the partition wall 30, it is prevented from reaching the tip of the partition wall, and ultimately, moisture does not penetrate into the internal accommodation space of the case equipped with the lighting board. This prevents malfunctions due to moisture.

In this way, the present invention has a triple waterproof structure through the composition of the molding material, waterproof space, and separation space, thereby providing superior waterproofness.

Meanwhile, the floor traffic light of the present invention is constructed by forming a traffic light insertion space (1) on one side of the sidewalk or road surface and then embedding it. If replacement is necessary due to damage or failure after embedding, it can be replaced more easily. A separate floor signal light seating member 70 is installed so that the

The traffic light insertion space (1) is formed by cutting to a width and depth that allow the floor traffic light to be inserted and fastened, and the floor traffic light mounting member (70) is inserted into the traffic light insertion space (1) and fastened to the floor surface. It is installed so that it rests on the.

The sea signal light seating member 70 is formed as a tube body with an open upper side and a cross-section in the shape of '∪', or as a plate body in the shape of '-' in the cross-section.

It is installed so that the floor traffic light is seated on the inner space or upper surface of the floor traffic light seating member 70, and when the floor traffic light seating member 70 is formed as a tubular body, the internal width is the same when the case 10 is inserted. It is preferable that it is formed to be the same as the width of the case 10 so that it is not pulled out when bound.

When the width of the floor traffic light seating member 70 is formed to be the same as the width of the case 10, the case 10 is in a forcibly bound state, and the pressure of the ground is applied to both sides of the floor traffic light seating member 70. As a result, the case 10 does not come out.

Of course, the inner width of the floor signal light seating member may be formed to be larger than the width of the case 10 by approximately 5 mm or less. In this case, because the case 10 can be easily removed, a separate binding guide member 75 is required.

The binding guide member 71 can be made of a cushion material and is provided between the floor signal light seating member 70 and the case 10 to serve as a medium so that the case 10 can be provided in a forcibly fastened state. do.

Even if the floor signal light seating member 70 is not provided, it does not matter much as the wire accommodated in the wire receiving groove of the wire storage part does not easily come into contact with urethane or concrete. However, in the case where the floor signal light seating member is provided, Since the contact itself is fundamentally blocked, replacement work can be easily performed when replacing the floor signal light in the future.

According to the present invention configured as described above, it completely blocks moisture due to its excellent waterproofing properties, thereby preventing malfunction of the lighting board due to moisture, allowing it to be used for a long time, and spare wires can be stored, preventing damage or breakdown in the future. It is an invention with excellent workability as it can be easily replaced when replacement is necessary.
