Description

Elastic body headlight shield for median strip}

The present invention is mounted on the upper part of the center divider installed in the center of a road running at a relatively high speed such as a highway, etc. to limit the light of the headlights of vehicles running on the opposite road, even at night or in bad weather. In addition to being able to easily identify the center divider, in the case of the existing steel mesh structure, the main material of the shielding film is urethane-based so that the steel shielding film is not separated and flies to the opposite lane to cause secondary damage to the other driver in the event of a center separator impact accident. Silicone-based. It is made of rubber-based elastomer, and has a structure that can be connected with a connecting rod with an LED diode luminous body inserted so that the light-shielding film and the light-shielding film can be assembled and installed. Furthermore, it is a structure in which the wire rope and the LED control line are passed through the inside of the connecting rod.

In general, the shading screen is installed on the road center divider and is a mesh-patterned steel or aluminum-based structure, which is installed to help secure the driver's visibility at night by blocking the headlights of vehicles coming from the opposite lane. Is a kind of

However, if most of these shading screens are impacted, there is a high risk of causing a serious secondary accident by falling into the opposite lane. Most of the existing shading screens are made of iron or aluminum, so they are not easily broken by impact and the weight is close to 30 kg each, in the opposite lane. In the case of flying, the other driver could be hit by a thunderbolt of tens of kilograms of iron without knowing the English.

Currently, in order to install a median divider on a road, it must undergo a crash test supervised by the Road Traffic Research Institute under the Road Corporation. The evaluation items of this test are that the vehicle must not break through the separator, the deformation distance of the facility is within 1m, and the vehicle will not fall. In addition, there is an item that damages to a third party by scattering accessory materials on or off the road to protect the driver. In the handbook of the Ministry of Land, Infrastructure and Transport, the weight of the subsidiary material scattered due to the appearance of the shading screen, etc., must be within 2kg, and the distance flying is limited to 1m ahead.

The severity of secondary accidents exists when the steel mesh shading film and accessories installed on the upper surface of the current center divider are scattered by impact.

The present invention is a light-shielding film that is placed on the road center divider. In the event of a central divider impact accident, the light-shielding film is removed and flies to the opposite lane to prevent secondary damage to the other driver, and restrictively block the lights of the headlights of vehicles running on the opposite road. For the effect of a light-shielding film, a number of through holes are formed and the main material is urethane. Silicone-based. It provides molding and attachment of rubber-based elastomers, and the light shielding film is limited in size to be molded in the longitudinal direction in consideration of economy, and the longitudinal connection between the light shielding film and the light shielding film is provided with a connection rod, and the connection rod in the form of a tube The goal is to solve the problem by constructing the wire rope and the LED control line to pass through.

The purpose of the elastomeric light shielding film is that the lower installation surface is attached to both sides of the center separator to prevent separation of the shielding film in the event of an impact of the center separator to prevent scattering and to minimize the impact even when colliding with a vehicle. Here, the elastic light shielding film is connected in the longitudinal direction using a connecting rod.At this time, a wire rope is also inserted into the connection rod insertion hole formed in the elastic light shielding film, so that the elastic light shielding film connected in the longitudinal direction is scattered by the wire rope when a vehicle collides and prevents the light shielding film from being separated. Do it.

The elastic light shielding film and the light shielding film are connected to each other so that the LED diode light-emitting body is inserted into the connecting rod so that it can be assembled and installed,

The connecting rod serves to support the shading film even in severe winds, and the LED light emitter and power are built into the connecting rod to serve as a safety guide light so that the central separator can be easily identified.

In addition, after attaching a solar cell and a capacitor to supply power by converting solar energy into electric energy from the side to a part of the center section,

A safety driving light consisting of two-color LEDs that light up and turn off in red or green and a speed detection sensor that detects the speed of the vehicle are built-in inside the connecting rod, and are connected to the speed detection sensor to signal that the vehicle is traveling at high or low speed. When delivered, the two-color LED of the safety driving lamp is turned on and off in red or green, and the LED of the safety guide lamp is also provided, including a control unit that turns on and off.

According to the present invention, the light shielding film formed of an elastomer material can be formed by adding various colors on the side of the design to realize aesthetics in road structures,

The elastomeric light-shielding film is designed to be limited to the upper surface of the center separator to provide support and attach both sides of the lower end of the elastic body light-shielding film directly to the left and right ends of the upper surface of the road center separator. By preventing departure, it can prevent scattering and minimize its impact even when colliding with a vehicle.

The elastic light shielding film is molded to a certain size in the longitudinal direction and limited so that it can be mass-produced, giving economic feasibility.

The lengthwise connection between the elastic light shielding membranes is provided with a connecting rod, and an LED light emitter is embedded inside the connecting rod, so that the central separator can be easily identified even at night or in bad weather, as well as a speed sensor that detects the speed of the vehicle. When the vehicle speeds up, it provides an effect that can induce safe driving by selecting the color of the LED illuminator and turning it off and on.

In addition, since the elastic light shielding light connected in the longitudinal direction by the connecting rod includes a wire rope therein, it has the effect of preventing the scattering of the elastic light shielding film and the separation of the light shielding film.

Figure 2 is a connecting rod member of the present invention

A preferred embodiment of the invention will be described in detail based on the accompanying drawings.

The terms to be described later are defined in consideration of functions in the present invention, and it is stated that they should be interpreted as a concept consistent with the technical idea of the present invention and a meaning commonly or commonly recognized in the art.

In the accompanying drawings, Figure 1 is a urethane-based. Silicone-based. It shows the elastomer light-shielding film 10 injection-molded of an elastomer material such as rubber, and is formed to a certain height and length by injection molding, and it is natural that various colors can be implemented by mixing pigments.

A plurality of glare prevention holes (10-1) through which the side portions of various shapes and sizes are penetrated are formed on the side of the elastic light shielding film to block a certain portion of the headlights of vehicles coming from the opposite lane, especially the direct sunlight from the high-beam headlights. It plays a role of preventing glare installed to help secure visibility. Not completely obstructing the view of the other lane means that if the view is completely blocked, the driving field of view is narrowed and the view of the opposite lane is hindered.

Here, the elastic light-shielding film 10 may be transparent or translucent due to material properties, and thus formation of the glare prevention hole 10-1 may be omitted in the case of a transparent color or a translucent color.

In addition, the elastic light shielding film has a connection rod insertion hole 10-2 through which one end of the connection rod to be described later is inserted in the longitudinal direction.

The connecting rod insertion hole is not represented in detail in the drawings with the wire rope 10-3 to be described later, but also serves to allow the operation line 10-4 for controlling the LED and the speed sensor to pass.

Here, the central separator of the expressway is usually formed of a concrete pouring body, and the steel posts are fixed at regular intervals with anchor bolts on the upper surface of the highway, and bolts are installed between the brackets on both sides of a light shield made of ordinary steel or aluminum and the bracket connecting the posts. It is common to do.

At this time, if an impact occurs on the body of the road median, the normal shading screen falls to the opposite lane, and by-products such as props are scattered, and there is a high risk of causing a serious secondary accident.

In order to prevent the risk of an accident, the elastic body light-shielding film 10 is formed by dividing the lower shape into one fixing part 10-5 and the other fixing part 10-6, and a fixing insertion hole in the one fixing part and the other fixing part ( 10-5) are formed respectively and are fixed with anchor bolts 10-7 in connection with the fixing insertion holes on the left and right sides of the upper part of the road center divider in the drawing.

In this case, it is possible to significantly prevent the scattering of by-products such as posts or brackets from the impact and the fall of the light shield to the opposite lane by separating the body of the elastic light shielding film directly to the road center separator without erecting the posts.

In Figure 2

It is intended to show that the shape of the elastic light-shielding film 10 can be variously formed by cross-section (A-TYPE) or (I-TYPE), but it is intended to show that the design can be modified even in a Z-TYPE shape.

In Fig. 2, the elastic light shielding film

It shows a connecting rod 20 that enables a plurality of connections in the longitudinal direction and prevents shaking of the elastic light shielding film in strong winds.

The connecting rod is divided into one tube (20-1), the other tube (20-2), and the center tube (20-3), and a male thread is formed on the outer circumference of the one and the other tube, and a female thread is formed on the central tube. It is a structure that is combined. This allows a fixed length to be adjusted with a screw thread and facilitates assembly and disassembly of the turnable light shield.

In particular, the central tube 20-3 is a transparent colored tube made of a silicone-based or urethane-based material having high hardness, and a perforated hole 20-4 is formed on the central tube. The role of the perforated hole is not indicated in detail in the drawing, but is intended to insert the LED 20-5, the light emitting diode and the small battery 20-6. After that, the perforated hole is closed with a rubber cover. As a result, it is visually confirmed from the outside that the LED is emitted in the transparent color central tube, and the central separator can be easily identified at night and in bad weather, leading to safe driving.

Also, although it is not shown in detail in the drawing, a small solar panel (20-7), power storage unit (20-8), LED control unit (20-9), and speed sensor unit (20-10) are provided at one end of the road median. It is possible to induce slow driving by continuously turning off and flashing LEDs for safety warnings caused by vehicle speeding or by repeatedly turning off and flashing the color of the LED light-emitting element in red and green.

At this time, for the continuous supply of power, the connecting rod insertion hole (10-2) formed through the elastic light shielding film and the connection rod are in the form of a tube, so that the operation line and the power supply line can be connected by wire. It will be self-evident that it will be a structure that is tightly bound to one end. The wire rope plays an important role in remarkably preventing the risk of causing a secondary accident by falling and scattering the elastic light shielding film in the opposite lane.

Herein, referring to FIG. 3

On the drawing, a rail member 30 that is extruded and integrated into a Π cross-sectional shape at the bottom and a Ⅱ cross-sectional shape is shown. A plurality of anchor coupling holes 30-1 are formed through the lower Π shape of the rail member. Anchor bolts (30-2) are connected and attached to both ends of the upper surface of the central separator, and a plurality of bolt coupling holes (30-3) are formed in the longitudinal direction in the upper Ⅱ shape cross section of the rail member. It is a structure in which the lower end of the I-TYPE elastic body light-shielding film is inserted into the shape II, and is connected with the through-hole 30-4 formed at the lower end of the I-TYPE elastic body light-shielding film, and is coupled with a coupling bolt 30-5.

Since the rail part structure is integrally attached with the road center separator for a long length along the road center separator, the entire rail part is prevented from separating even from the impact of a vehicle, and it is less likely to be carved and scattered separately.

Subsequently, the installation speed is also doubled in the elastic light shielding film assembled on the rail part, so that installation in a short time is possible.

The present invention is not limited by the above-described embodiments and the accompanying drawings, and various modifications and applications not illustrated within the scope of the present invention are possible, as well as substitution of components and other equivalent embodiments. Since it can be changed, the contents related to modifications and applications of the features of the present invention should be interpreted as being included within the scope of the present invention.
