Highway Protection Barrier {HIGHWAY PROTECTION BARRIER}

The present invention protects a vehicle, such as safety barriers, parapets, impact attenuators, terminals and transitions, barriers made of flexible materials such as rubber or other elastomers. Related to highway protection barriers called vehicle restraint barriers, elastic members are provided inside to provide adequate stiffness to the barrier or fence to prevent twisting and damping caused by a vehicle crash. Allow.

Obviously, highway protection barriers are located on the side of the road or in the middle of the road, as a means of demarcating prohibited areas, and subsequent damage from vehicle accidents or crashes caused by carelessness or other uncontrollable situations on the road. It is provided as a means to reduce.

To provide highway protection barriers.

Vehicle protection systems, such as fences or protective barriers, known as "guide rails," are generally made of rigid members and are subject to permanent deformation upon impact, which can occur suddenly and cause severe damage to the vehicle due to the stiffness of the fence or barrier. In addition to causing damage, the occupants in the vehicle are also seriously injured.

In addition, if, for example, the barrier is made of fully flexible discrete members or a bollard, they will return to their original form at the end of the impact, but the driver will not realize this and will be able to Since they can be dragged and cause permanent damage, carelessness or shock resulting from not seeing these barriers can damage the vehicle and cause permanent damage to the member or protective posts, thus causing collisions with the barrier to the driver of the vehicle. There is often a need to warn.

The highway protection barrier proposed here is designed to solve the above problems as a simple but effective solution.

More specifically, the barrier of the present invention includes a flexible body made of rubber or other material having elasticity, preferably a material based on a regenerated tire, and the like, and a plurality of elastic members are embedded in the body of the fence itself. And the protection pillars made of the same material as the body of the fence can be arranged in a cylindrical shape, and the elastic members are sufficiently rigid and full to the fence including a spring as a member integrated therewith. It provides elasticity due to the properties of the materials that make up the assembly, and the impact applied to the fence in accordance with the manner provided to reduce or move the impact of the fence and the crashed vehicle not only absorbs the amount of impact of the vehicle, but also The elastic members of the spring (protective pillar that is part of the spring or the spring) is characterized in that the deformation The.

In another embodiment, the barrier has a curved shape, inwardly concave shape, the curved shape is equally applicable to internal elastic members configured as damping means in the impact acting on the fence or barrier. It features.

The configuration in which the body of the barrier has a curved shape provides greater shock absorbing ability than when the body of the barrier and the elastic member therein are vertical.

In the curved configuration of the barrier, the elastic member may be formed by a cylindrical body consisting of a protective pillar and a helical spring embedded in the protective pillar and connected to each other in horizontal sheets to form an interior of the assembly. To strengthen.

In another embodiment of the barrier having a curved configuration, the inner elements of the resilient members are metal strips having a rough surface to improve adhesion to the resilient material and the helical spring itself, Consisting of a mesh or sheet, in another alternative embodiment said inner elements are comprised of vertical or horizontal rods, both the body of the barrier and the elastic members being more efficient at impact It has a common feature to have a curved shape for absorption by

Therefore, the described highway protection barrier, in particular a barrier having a curved configuration, is made of an elastic body such as rubber and thus absorbs the impact of a vehicle collision and deforms the internal elastic members in the same manner as the body of the barrier, thereby impinging on the barrier. Attenuation-absorption of a vehicle is achieved to prevent the occupant of the crashed vehicle from being injured by a sudden impact and to minimize damage to the vehicle body.

The barrier may be integrated with impact sensing means for activating the elements that signal with sound and / or light.

In another embodiment, the body of the barrier is a shock sensing device incorporating a means for triggering a warning signal, such as a protective column, comprising a pressure sensor or a device for detecting a change in inclination of the protective pillar, or another similar conventional device. The means can be formed by independent members integrated into the circuit, so that when the contact of the vehicle is detected by the circuit, a light indicator output through one or more speakers or similar devices or properly placed in the fence Warning signal is generated, which is long enough to be visible from the driver's position in the event of a collision.

In another embodiment, the sound / light signal circuit does not need to be integrated into the protection pillar itself and can be disposed outside the protection pillar, so that the circuit associated with the impact sensing means arranged in each protection pillar may be sound / light. Connected with a specific type of radio frequency transmitter that emits an activation signal that will activate the signal circuit, a group of guard posts require only one sound / light signal circuit, in which case the circuit is the corresponding signal. Will be integrated with the corresponding radio frequency receiver module.

Thus, the system automatically and reliably warns the driver of the possibility of the vehicle colliding with the guard post, preventing damage to both the vehicle and the guard post.
