Description

Roller type buffer being installed on guardrail}

The present invention relates to a roller type shock absorber of the guard rail that can be easily installed on the guard rail installed at the edge of the road to prevent vehicle shock and prevent the occurrence of secondary accidents. The rollers are fixedly installed on the two-stage guard rail or the triangular bent section of the three-stage guard rail to safely drive the vehicle in the forward direction while mitigating the primary impact with a cushioning roller when the vehicle is out of the roadway. The present invention relates to a roller type shock absorber of a guardrail capable of preventing secondary accidents.

Conventional guard rails are bent in two or three stages so that the triangular bent portion is directed toward the center of the road, and is installed as bolts and nuts at posts buried in the ground at regular intervals, and the triangular bent portion is used for large or small vehicles. It is installed to mitigate the impact in the event of a collision.

However, the above guardrail structure has a problem that the buffering action is dependent on only one guardrail, and it can cope with minor collisions, but a collision of a certain level or more is caused by the reaction of the guardrail and the vehicle is bounced off the road and the secondary vehicle is driven. The risk of a serious collision is high, and the reaction causes the vehicle to be in an uncontrollable state, putting it in a state of severe shaking and shaking so that the driver cannot operate the steering wheel. There is this higher issue.

In order to solve the disadvantage of the guard rail, a roller-type guard rail in which a plurality of buffer rollers are fitted at predetermined intervals is designed.

However, the roller-type guard rail as described above is a completely independent structure, which is incompatible with the existing guard rail, and thus the existing guard rail must be removed and reinstalled. have.

The object of the present invention, in view of the conventional problems as described above, easily installed on the already installed guard rails to overcome the problems of the conventional guard rails, to more safely alleviate the impact of the vehicle, and to prevent secondary accidents It is to provide a roller-type shock absorber of this possible guardrail.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a plate-shaped steel fixed by fastening means to the buried post (1) at regular intervals are bent in multiple stages to the two-stage or three-stage guard rail (3) in which two or three triangular bent portions (2) are formed. In this case, a buffer roller 5 formed of rubber, urethane, or the like is inserted in the center of the shaft 4 on which both ends are threaded, and a bracket 6 supporting the shaft 4 on which the buffer roller 5 is inserted is provided. ) Is fixed to the fastening hole 7 drilled in the triangular bent portion 2 of each stage by the number of the stages with bolts 8 and nuts 9, and nuts 9 'are fastened to both ends of the shaft 4. It is characterized in that the formed.

Here, the present invention has a different structure according to the type of the guard rail (3), in the case of the two-stage guard rail (3) one buffer roller (5) is inserted into the shaft (4) as shown in Figure 2 It is installed between the bent portion (2), in the case of the three-stage guard rail (3), two buffer rollers (5) are inserted into the long shaft (4) as shown in Figure 3 is installed between the triangular bent portion (2) Lose.

In the figure, reference numeral 7 'denotes a fastening hole drilled in the bracket 6, and 9' denotes a nut fastened to threads machined at both ends of the shaft 4.

The present invention, as described above, enables the prevention of secondary accidents by guiding safe braking and normal driving of a vehicle that has fallen out of the lane due to a broken vehicle or an immature driving.

The guard rail 3 is formed in two or three stages for the distinctive protection of a large vehicle and a small vehicle. Accordingly, one or two shock absorbing rollers 5 are inserted into the shaft 4. Regardless of what kind of guardrail 3 is already installed as described above, the present invention can be installed, and it is useful to prevent the hassle and financial loss of removing and reinstalling the existing guardrail 3.

The present invention uses a conventional guard rail (3), drills a fastening hole (7) for fastening the bracket (6) to the triangular bent portion (2) of the guard rail (3), the buffer roller (5) is a triangle The bracket 6 is positioned to support the shaft 4 on the upper and lower ends of the buffer roller 5 so as to be located between the bent portions 2, and the fastening hole 7 'and the guard rail 3 drilled in the bracket 6 are supported. The fastening hole 7 drilled in the c) is fixed to the bolt 8 and the nut 9, and both ends of the shaft 4 are fastened to the nut 9 ′ to fix the shaft 4. In this way, the present invention is provided with a buffer roller 5 in succession at regular intervals along the guard rail (3), this state is shown in FIG. Here, the buffer roller 5 is rotated on the shaft 4, and the function of the buffer roller 5 can be added by using a material having excellent elastic force such as rubber or urethane, and in some cases, a steel pipe It can also be formed. In addition, it is not only installed on the guard rail 3 of the road side as described above, but also can be used in various ways, such as installed on the curvature of the road, the center line, the railing of the piers and the wall of the underground driveway.

In the present invention formed as described above, if the driver breaks the lane due to a failure or driving immaturity and hits the guard rail 3, or a driver who recognizes the failure to brake by the collision to the guard rail 3 by means of emergency braking. As it is useful for, the shock absorbing roller 5 made of elastic material primarily relieves the impact of the vehicle colliding with the guard rail 3 at an angle. The vehicle in which the shock is primarily reduced is cushioned again by the guard rail 3 to improve stability compared to the conventional guard rail 3, thereby stabilizing the vehicle as the driver intended.

In particular, since the shock absorbing roller 5 is rotated on the shaft 4, the vehicle collided with the shock absorbing roller 5 is stably guided in the normal traveling direction of the vehicle while the shock is alleviated by the shock absorbing roller 5, so that the guard The risk of being thrown off by reaction by the rail 3 is reduced so that the driver can correct the steering wheel and find the original normal driving direction.

Accordingly, the present invention has a secondary accident due to deformation of the guard rail 3 and collision with another vehicle that is normally driven by the vehicle being bounced off the road in response to a collision by the conventional guard rail 3. As well as being eliminated, there is a feature of the present invention in that this action can be implemented in the guard rail 3 that is already installed.

In this way, the present invention can be implemented using the existing guard rail (3) installed for the safe braking of the accident vehicle and the guidance to the normal driving state, and the hassle and financial loss of removing the existing guard rail (3) By solving the problem, the present invention can be easily carried out, there is an effect that can prevent the damage and physical damage caused by the vehicle accident.
