Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems in conventional guard rails wherein (1) they merely absorb and disperse collision energy by the rupture of the guard rail and a vehicle in the collision thereof with the vehicle and (2) frequently cause dead and injury accidents since the protection effect of the guard rails is not sufficient in the entry of a violently running vehicle into pedestrians, entry of a vehicle into a facing lane, and collision thereof with signal lamps, street lights, telegram columns, street trees, and posts of highways in order to risks on roads which daily fall on all peoples and produce unavoidable risks and fear. <P>SOLUTION: The direction of the vehicle is corrected while relieving the collision energy of the violently running vehicle by the guard rail in which a crawler-like or conveyor belt-like device or equipment having racing or rotating resistance is incorporated. Consequently, the safety of occupants can be improved to prevent a secondary accident such as rear-collision. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a guardrail for roads.

Conventionally, various types of guard rails have been installed on roads, such as molded steel plates, iron pipes, wire steel, etc., and there are many roads with only white or yellow lines in the median strip. There are signal poles, streetlights and other iron poles, telegraph poles, street trees, highway pillars, etc. along the side lines and median strips, and these become great weapons if vehicles hit each day. Many lives are lost

However, when a vehicle contacts or collides with the current guardrail, the collision energy is absorbed and diffused by the destruction of both, and the vehicle, the passenger, and the guardrail are both severely damaged by the impact.

Also, on roads where the median is white or yellow, avoid the worst frontal collision that can cause death or injury if a vehicle on the opposite lane jumps over the median. It is a current situation that is not possible, is a fault of the current road, is one of the most common daily disasters that many people encounter most, and just hope that oncoming vehicles do not break the principle of trust The biggest fear on the road,

Currently, most of the guardrails installed on the road are steel plates, steel pipes, etc., and the vehicles are also steel plates. For this reason, if the vehicle and the guardrail come into contact with each other and an accident occurs, you can experience it on a daily basis. Encountering loud sounds without noise, causing a panic situation and inability to respond calmly, expanding damage

  Therefore, prevention and mitigation of collision accidents between the aforementioned vehicles and guardrails or iron poles such as signal lights, lighting lights, telephone poles, street trees, highway columns, protection of passengers, secondary accidents and vehicle fires The goal is prevention, runaway on sidewalks, prevention of frontal collisions by jumping into oncoming lanes, and reduction of loud acoustic collision noise in the event of an accident. Is trying to build a solid and safe road

  In other words, caterpillar or conveyor belt-shaped devices can be rotated and installed as road sides or median strips (eg, Fig. 1 and Fig. 2).

  The rotation of the above-mentioned devices may be no load or a load may be applied.

  Also, the rotational resistance of each rotating body may be set individually depending on the use site and use conditions, and may have a difference.

  When a runaway vehicle collides with the above-mentioned guard rail, the caterpillar or conveyor belt rotates and absorbs the energy of the collision, and the deformation performance of both the collision vehicle and the guard rail, the direction correction of the collision vehicle, and the guidance performance are It will improve, prevent secondary accidents, reduce damage, and save the lives of passengers

  For example, as shown in FIG. 2, the guard rail is installed on the side of the road, and the conventional guard rail can be used or modified even if it is modified.

  In addition, as shown in Fig. 3 (overhead view), it is installed in the center of the road as a median strip.

  Also, if each rotating body is made of rubber, synthetic resin, or other elastic body, or has a structure in which an elastic body is wound around the outer skin, the effect of absorbing collision energy can be improved.

1 is a side view of the guard rail, FIG. 2 is a plan view of the guard rail, and FIG. 3 is a front view (overhead view) of the guard rail.

Explanation of symbols

1 is the main body of the guard rail 2 is the rotating part of the guard rail 3 is the main body of the guard rail 4 is the rotating part of the guard rail 5 is the main part of the guard rail 6 is the rotating part of the guard rail 7 is the idling of the guard rail 8 which is a part is a road surface

Claims (1)

    A guardrail characterized in that a caterpillar-like or belt-conveyor-like device that holds idling or rotating resistance rotates due to a vehicle collision.
