Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushion cover for covering a terminal support of a road guard cable.

[0002]

[Prior Art] In snowy areas such as Hokkaido and Tohoku,
Car tire slip accidents often occur due to road surface freezes. A guard cable is installed based on a specified standard at the curved part where it is considered that there are many accidents.

The original function of the guard cable is to stop the vehicle by absorbing the collision energy by the elasticity of the guard cable and the fall of the intermediate column when the sliding vehicle collides with the guard cable at an angle. Is.

However, in practice, it is said that the driver thinks that it is dangerous to go to the guard cable, and therefore tends to intentionally direct the vehicle to the guard cable end column when slipping occurs. In addition, the end of the guard cable is often the starting point of the bend of the road, and it can be said that it is the place where slippage occurs most easily.

As a result, in many cases, the automobile collides head-on with the guard cable end column and the impact with the tough guard cable end column causes the driver to suffer great damage in spite of the attempt to avoid the danger. Will receive.

In order to prevent this, it has been proposed to wrap the guard cable end struts with a cushion cover entirely made of soft cushioning material. However, since an automobile usually slides at a speed of about 50 km / hr, it is difficult to think that a cushion cover having such a structure can completely absorb the momentum depending on the collision direction of the automobile. It is predicted that a collision with a cable end brace cannot be avoided.

That is, in the conventional cushion cover,
It does not consider how to effectively use the original function of the existing guard cable, and it can be said that the safety measures are attempted by relying only on the flexibility of the cushioning material that forms the main body of the cushion cover. .

[0008]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cushion cable end support cushion cover which can reduce damage to an automobile or a driver by adding a reinforcing material.

Further, an object of the present invention is to guide an automobile coming toward the guard cable end support to the guard cable body side so that the original function of the guard cable can be effectively exhibited. The purpose is to provide a cushion cover for a pillar.

[0010]

The cushion cover 10 for a guard cable end column according to the present invention has a reinforcing member 1 provided therein, which will be described below with reference to the reference numerals in the accompanying drawings. The strength of the reinforcing member 1 is preferably set to be slightly weaker than that of the automobile bumper 12 and the guard cable end support column 3.

In another aspect of the present invention, the reinforcing member 1 is arranged eccentrically in the direction opposite to the guard cable main body 4 when viewed from the geometrical center of the entire cushion cover 10 in a plan view.

[0012]

The cushion cover 10 is mounted so as to enclose the guard cable end support column 3. When the vehicle 11 collides with the guard cable end support column 3 and the collision energy is at a sufficiently low level, the cushion cover 10
It is absorbed by the elastic deformation of the cushioning material 6. When the collision energy exceeds a certain level, the portion that cannot be completely absorbed by the cushioning material 6 is absorbed to some extent by the elastic deformation or plastic deformation of the reinforcing material 1, and the damage to the automobile 11 and the driver is alleviated.

When the strength of the reinforcing member 1 is set to be slightly weaker than that of the automobile bumper 12 and the guard cable end column 3, the deformation of the reinforcing member 1 occurs before the automobile bumper 12 and the guard cable end column 3 to reinforce. The material 1 effectively functions as a shock absorbing damper.

When the driver intentionally moves toward the guard cable end support column 3, the driver places the guard cable end support column 3 at the geometric center of the cushion cover 10.
Based on the premise that the vehicle is present, the traveling direction of the automobile is directed to the center of the cushion cover 10.

However, since the reinforcing material 1 is eccentrically arranged on the opposite side of the guard cable body 4 from the geometric center of the cushion cover 10, the cushion cover 1 is provided.
The vehicle 11 colliding with the center of 0 does not collide with the center of the guard cable end column 3, and the vehicle 11 is mechanically moved to the guard cable main body 4 side by the reinforcing member 1 existing as a resistance element diagonally forward. It is guided and slowed down and stopped by the original function of the guard cable.

[0016]

EXAMPLES In each of the examples shown in FIGS. 1 to 3, the circular pipe constituting the reinforcing member 1 is a high-tensile steel material having a diameter of 60 k, and as an example, the guard cable terminal column 3 having a diameter of 114.3 mm has a diameter of 250 mm. I used a thickness of 5 mm. The outer shell of the cushion cover 10 is made of synthetic resin, and a foam material is used as the cushioning material 6 inside.

The cushion cover 10 is formed with a vertical groove portion 14 which is opened on one side surface and a lower surface until it reaches the back of the reinforcing member 1. When the cushion cover 10 is attached to the existing guard cable end support column 3, This is done by fitting the vertical end groove portion 14 so that the guard cable end column 3 and the guard cable 4 are fitted therein. Since the end fixing bolt 5 of the guard cable is located on the back side of the reinforcing member 1 which is the deepest part of the vertical groove portion 14, it does not affect the conventional guard cable construction method.

The reinforcing member 1 is arranged eccentrically on the guard cable terminal column 3 side with respect to the geometric center of the cushion cover 10. Therefore, as shown in FIG. 1, the automobile 11 traveling in the direction of the arrow A has the cushion cover 1
When the vehicle hits the center of 0, the cushion cover 10 breaks and rotates in the direction of arrow C, that is, in the counterclockwise direction, so that the vehicle 11 does not collide head-on with the guard cable end support column 3 at the arrow B. Proceed in the direction of the guard cable body 4 as shown.

In the embodiment shown in FIG. 1, since the reinforcing material 1 is composed of a circular tube crushed from one side in the radial direction to the entire length in the longitudinal direction, the manufacturing of the reinforcing material 1 is simplified and facilitated. Become. When the crushing process of the circular pipe is performed according to the outer shape of the guard cable end support column 3,
The cushion cover 10 can be easily attached to the existing guard cable end column 3 by simply covering it from above,
No special fixing work is required.

In the present situation where many guard cables are already installed in snowy areas and it is practically impossible to modify them, the ease of manufacture and the ease of installation due to the simplicity of this structure make traffic safety easy. It is very useful in establishing measures early.

In the embodiment shown in FIG. 2, the reinforcing material 1 of the cushion cover 10 is arranged on the side of the lane diagonally in front of the guard cable terminal column 3 when viewed from the traveling direction of the lane 7 which is the target of the guard cable 4. There is. Therefore, if the automobile 11 deviates more outward than the center of the cushion cover 10, the automobile 11 will hit the reinforcing member 1 and will not directly hit the guard cable end support 3. The reinforcing material 1 properly fulfills the role of shock absorption.

In the embodiment shown in FIG. 3, the surface 9 of the cushion cover 10 is provided with an arrow 9 pointing toward the guard cable body 4 by printing or the like. Therefore, the driver is psychologically guided toward the guard cable body 4 by the arrow 9, and the automobile 11 is decelerated and stopped by the original function of the guard cable. As for color,
The yellow arrow is used as an example on a black background, which is the clearest combination and has good luminescence even at night.

[0023]

As described above, in the cushion cover of the present invention, since the reinforcing material 1 having a required strength, preferably a strength slightly weaker than the automobile bumper 12 and the guard cable end support 3, is provided inside, A higher cushioning effect can be obtained as compared with the conventional cushion cover, and damage to the automobile and the driver can be reduced.

The reinforcement 1 is used as a cushion cover 1
Guard cable body 4 as seen from the overall geometric center of 0
Since it is arranged so as to be eccentric in the direction opposite to, the car 11 is accurately guided to the side of the guard cable main body 4 while using the psychology of the driver, who is the winner, toward the guard cable end column 3. Since the original function of the guard cable can be effectively exerted, traffic safety can be dramatically improved.
