Description

Roller type buffer being installed on guardrail}

The present invention relates to a roller type shock absorber of a guard rail that can be easily installed on a guard rail installed at the edge of a road to prevent vehicle shock and prevent the occurrence of secondary accidents. By installing two shock absorbing rollers on the guard rails that are already in use and using them, the shock absorbing rollers induces the vehicle to move forward safely while mitigating the primary impact as the shock absorbing rollers collide with the guard rails. The present invention relates to a roller type shock absorber that can be prevented.

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 two-stage guard rail is intended to protect small vehicles. However, the height of the two-stage guard rail is high due to the protection of the medium and large vehicles. Is higher than the two-stage guard rail. Therefore, there is a problem that the effective small vehicle protection is insignificant, and the buffering action is dependent on only one guardrail, and it can cope with a minor collision, but a collision of a certain level or more is caused by the reaction of the guardrail. There is a high risk of secondary collisions, and the reaction causes the vehicle to be in an uncontrollable state, putting it in a state of severe rocking and shaking so that the driver cannot handle the steering wheel. There is a higher risk of problems.

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, in order to protect the small vehicle effectively on the already installed guard rails two or more buffers on one axis to install a buffer roller in the middle and bottom of the guard rail By inserting a roller and installing it in the existing guard rail to provide a safer cushioning device of the guard rail that can more safely alleviate the impact of small vehicles, and can prevent secondary accidents.

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, two buffer rollers 5 formed of rubber, urethane, or the like are inserted in the center of the shaft 4 on which both ends are threaded, and a bracket for supporting the shaft 4 on which the buffer roller 5 is inserted is inserted. 6 is fixed to the fastening hole 7 drilled in the triangular bent part 2 by the bolt 8 and the nut 9, and the channel bracket 10 in which the plurality of fastening holes 7 ′ is drilled is a post 1. The nut (9) is fixed to the bolt (8 ') and the nut (9'), and the nut (9) is screwed on the thread (4) of the shaft (4) protruding into the lower bracket and the upper bracket (6) of the channel bracket (10). ''), Characterized in that one of the two buffer rollers 5 is formed between the triangular bends 2 and the other is located below the lowermost triangular bends 2. do.

In the figure, reference numeral 7 '' is a fastening hole drilled in the bracket 6.

In this way, the present invention provides a safe braking and normal driving direction of a small vehicle that is separated from the lane due to a failure or inexperience due to a buffer roller 5 installed between and below the triangular bent portion 2 of the guard rail 3. By catching it is possible to prevent secondary accidents.

The guard rail 3 is formed in two or three stages for the distinctive protection of large and small cars, and the installation height of the guard rail 3 is not purely intended for the protection of only small vehicles when the two-stage guard rail 3 is installed. In consideration of the installation of large and medium-sized vehicles, it is inevitable that the small car cannot be effectively protected. The problem is further exerted in the case of the three-stage guard rail 3.

However, the present invention is to install two shock absorbing rollers (5) downward on the two-stage guard rail (3) and the three-stage guard rail (3) only for medium and large vehicles in consideration of the protection of such medium and large vehicles. Since the installation of the present invention can be installed in the already installed two-stage or three-stage guard rail (3), the hassle and financial loss of removing and reinstalling the existing guard rail (3) is useful.

That is, the present invention is to use the existing two-stage or three-stage guard rail (3), for fastening the bracket (6) to the lower two triangular bent portion (2) of the two-stage or three-stage guard rail (3) The fastening hole 7 is drilled, and the channel bracket 10 is fastened to the post 1 with the bolt 8 'and the nut 9', and the two buffer rollers 5 respectively have two triangular bent portions ( 2) the bracket 6 supports the shaft 4 portion of the upper end of the buffer roller 5 and the shaft 4 portion between the two buffer rollers 5 so that the bracket 6 is positioned between and below the lower triangular bend 2; , The lower end of the shaft (4) is inserted into the fastening hole (7 ') of the channel bracket 10, the fastening hole (7' ') and the fastening hole (7) drilled in the guard rail (3) It is formed by fixing the bolt 8 and the nut 9 and fastening the shaft 4 by fastening the nuts 9 '' at both ends of the shaft 4.

As such, the present invention is continuously formed at regular intervals along the two-stage or three-stage guard rail 3, and 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, as described above, it is not only installed and used in the second or three-stage guard rail (3) along the edge of the road, but also can be installed in various ways such as the curved part of the road, the center line, the railing of the pier and the wall of the underground driveway.

According to the present invention installed as described above, a small vehicle, such as a vehicle that has fallen out of a lane due to a failure or driving immature, collides with a two-stage or three-stage guard rail 3, or a driver who recognizes a failure has a guardrail as a means of emergency braking ( It is useful when braking by 3), and the shock absorbing roller 5 of the 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 so that the stability is improved as compared with the conventional guard rail 3, so that the driver can stabilize the vehicle as 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, the installation position of the shock absorbing roller 5 can be lowered in order to effectively protect a small vehicle, and this feature can be implemented in the guard rail 3 that is already installed.

In this way, the present invention can be easily installed on the existing guard rail (3) installed for the safe braking of the accident vehicle and guidance to the normal driving state, the guard rail (3) of the installation height is not suitable for small vehicle protection By installing the buffer roller (5) on the lower side of the existing guard rail (3) to solve the problem of the trouble and financial loss can be easily installed the present invention to prevent damage to life and physical damage from vehicle accidents There is a preventable effect.
