JPH1060830A - Anti-dazzle board capable of being connected to guard rail in expressway - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable a large-sized truck to direct a headlight upwards, and to ensure a visual field widely by assembling a frame using an iron material, forming an upper layer of a plastic board, to which wind holes are formed, and connecting the plastic board to an existing guard rail by metal fittings. SOLUTION: A frame using an iron material 1 is assembled, the upper layer of the frame is formed of a plastic board, to which wind holes 2 are formed, and the plastic board is connected to an existing guard rail 4 by metal fittings 5, 6. One anti-dazzle board and another are coupled successively by recessed sections and projecting sections, and the picture, etc., of trees are drawn on the surfaces of the boards. Unstable feeling due to the heightening of height is reduced by preparing the surfaces of the boards of plastics and lightening the boards. Height is heightened and the light of a headlight for a large-sized truck can be interrupted by installing the anti-dazzle board to the existing guard rail 4, and the headlight is directed upwards for the large-sized truck, and a visual field can be widened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-shielding plate which can be connected to a guardrail of a median strip on an expressway.

[0002]

2. Description of the Related Art In a conventional light-shielding plate and glare prevention net, the height from the ground is about 1500 mm, and when a large truck runs with headlights facing upward, it is dazzling to oncoming vehicles.

[0003]

At present, the headlights of passenger cars are set to have a field of view of about 100 meters forward when facing upward and about 30 meters forward when facing downward.
To stop a car within 30 meters ahead, you must run at a speed of 40 to 50 kilometers per hour. However, they run at speeds of over 80 km / h on highways. In other words, if you are traveling in a field of view of about 30 meters with the headlights facing down,
Even if you find an obstacle 30 meters ahead and step on the sudden brakes, it is not enough. Not only that, they could even slip and cause a major accident. Next, a case where the vehicle is driven with the headlights facing upward in a field of view of about 100 meters.
It has the effect of a light shielding plate and a glare prevention net which are currently widely used, and can prevent glare to oncoming vehicles. However, when a large truck turns the headlights upward, the height of the currently popular light blocking plate and anti-glare net is not enough, and the headlights hit the oncoming vehicle, which is very dazzling. May cause. That is, it is considered that the current light shielding plate and glare prevention net do not have the effect of preventing glare when a large truck runs at night. The present invention has been devised to solve these disadvantages.

[0004]

According to the present invention, the surface of the light-shielding plate is made of plastic or aluminum to reduce the weight, thereby reducing the sense of instability due to the height increase. In addition, by providing an air hole on the surface, it is hard to be affected by the cross wind.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a frame is assembled by using an iron material. The upper layer is formed of a plastic plate or an aluminum plate provided with air holes. Then, it is connected to an existing guard rail having a height of about 600 mm by a mounting bracket.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment will be described with reference to FIGS.
The upper layer of a frame of 0 mm × 1200 mm is formed of a plastic plate or an aluminum plate (3) provided with an air hole (2) having an opening of 150 × 200 mm. Then, the mounting bracket (5.6) is attached to the existing guardrail (4) having a height of about 600 mm.
Connect with The light shielding plate and the light shielding plate can be connected one after another by the concave portion (7) and the convex portion (8). Then, a picture of trees or the like can be applied to the surface of the light shielding plate.

[0007]

The present invention has the above-described structure, and has the following effects.

[0008] By attaching the light-shielding plate of the present invention having a height of 1200 mm to an existing guard rail having a height of about 600 mm, the total height becomes 1800 mm and the light of the headlights of a large truck can be almost blocked. You can also feel free to turn the headlights upward and widen your field of view. This enables early detection of obstacles, which is effective in preventing accidents.
