Description

The present invention relates to a shock absorber for a vehicle.
The present invention also relates to a vehicle shock absorber that is deformed to prevent damage to the vehicle when the vehicle collides.

  Furthermore, the present invention relates to an impact shock absorber for a vehicle that does not cause deformation or breakage to such an extent that the shock absorber body cannot sufficiently exhibit its performance.

Conventionally, the vehicle shock absorber shown in FIG. 3 is known.
The vehicle shock absorber shown in FIG. 3 has a shock absorber body 100 having an elastic force to absorb the shock,
An extension member 200 attached to the main body 100 and extending on the road surface is provided.
The main body 100 is formed of foamed plastic or foamed rubber in a triangular prism shape.

  When the vehicle rides on an extension member 200 made of a resin material reinforced with polyester fiber, polyamide fiber or the like, one end of which extends in the vehicle entry direction and the other end is wound around and fixed to the main body 100, The main body 100 and the extension member 200 are prevented from being blown off, and the vehicle is braked.

The main body 100 of this type of shock absorber for a vehicle is uniformly formed as a whole by foamed plastic.
As a result, there has been a problem that sufficient braking cannot be obtained at the time of a vehicle collision.
In particular, in order to facilitate the carrying of the vehicle shock absorber, when the foam density of the main body 100 is reduced to reduce the weight, the vehicle shock absorber is bounced off at the time of a vehicle collision and the wind Caused the problem of moving.

On the other hand, when the foam density of the main body 100 is increased, it is difficult to carry and there are many opportunities to drag and carry the main body 100, and the main body 100 and the extension member 200 have a problem of being worn and damaged at an early stage.
As such a vehicle shock absorber, a vehicle shock absorber disclosed in Patent Document 1 is known.

Furthermore, a vehicle shock absorber disclosed in Patent Document 2 is known as an improvement of such a vehicle shock absorber.
As shown in FIGS. 4 and 5, the shock absorber for a vehicle includes a shock absorber body 100 having a triangular prism shape having an elastic force to absorb an impact, and an extension member 200 attached to the main body 100 and extending on a road surface. Thus, the void 400 is provided at a position away from the road surface of the main body 100, and the mass body 300 having a density higher than the density of the members constituting the main body 100 is arranged on the side in contact with the road surface.

As a result, the impact shock absorber for the vehicle can be easily carried and, as shown in FIG. 5, when the vehicle 5 collides, the impact shock absorber for the vehicle does not jump off and moves in the wind. I was able to solve the problem.
However, the shock-absorbing performance due to the vehicle collision is satisfactory, but when the sample is actually provided to the construction contractor and used at the construction site, the shock-absorbing body 100 is damaged and deformed so much that the original shape is not retained. Problem has occurred.

In actual use at the construction site, other construction equipment (color cones, regulatory signs, bulletin boards, generators, etc.) is loaded on a truck or the like and moved back and forth on the construction site. The reason is that heavy equipment, etc. can be repeatedly placed, thrown down, thrown and piled up repeatedly, or handled violently.
As a result, the buffer body 100 has caused problems such as deformation and breakage to such an extent that its performance cannot be sufficiently exhibited.
