The present invention relates to a shock absorber for road struts, and more particularly, to install a shock absorbing member on a road strut, but to incorporate the shock absorbing member into a case to protect it normally and to crush the case together in case of collision, thereby improving the cushioning property. The outer periphery of the case relates to a multifunctional road holding shock absorber treated to prevent illegal advertisements to be attached.

In general, road struts are telephone poles, traffic light struts, street light struts, and other struts installed around roads.

Since the road struts are made of metal or concrete material in consideration of the propulsion strength, when the vehicle collides, the impact is transmitted to the driver as it is, causing frequent injuries.

In Korea Utility Registration No. 303370, a shock absorbing member that can absorb a shock in a vehicle crash is installed on a road post. However, the conventional shock absorbing member is a circular arc shape that simply envelops the strut, and is a synthetic rubber structure having a hollow space therein. Therefore, the shock absorbing member can absorb the primary shock. However, the elastic restoring force of the synthetic rubber is transmitted to the driver as it is, thus absorbing shock. There was a downside to this falling.

The present invention was developed in view of the conventional problems, an object of the present invention is to arrange a plurality of partitions of the cushioning member surrounding the strut in an arc shape, these buffer members are built in a separate case so that the usual protection, when the vehicle crashes The case is primarily crushed to absorb the shock, and the shock absorbing member to be cushioned by the secondary shape deformation, but the case is made of a non-restored metal material to remove the elastic repulsive force of the shock absorbing member because of the impact Absorption is improved, and the shock absorbing member and the case in the case of collision can be selectively replaced to reduce the increase in the cost of replacing all, and to provide a road holding shock absorber convenient to assemble the road holding.

And another object of the present invention is to provide a buffer for the road holding to improve the aesthetics of the road by preventing the illegal advertisement is attached to the band wound around the outer peripheral surface of the case surrounding the buffer member.

In order to achieve the above object, the present invention provides a plurality of cases which are not fully restored and restored to their original state by being wrapped in a radially divided outer periphery of the road strut and being distorted during a collision of the vehicle; The case is separately embedded in each case, and the second shock absorber when the vehicle crashes, a plurality of shock absorbing members that do not generate a resilience reaction due to the case and the upper and lower ends of the case to the support to secure the case to the outside of the support Consists of upper and lower caps that allow them to lie radially at the perimeter.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a shock absorber according to an embodiment of the present invention, and FIG. 2 is a front sectional view of the shock absorber according to an embodiment of the present invention mounted on a support. A plurality of conical cases 10 are provided so as to radially divide and wrap the outer periphery of the support 50. The case 10 is formed of a metal material having a thickness capable of bending deformation during collision of the vehicle and having no elastic restoring force. The interior of the case 10 is provided with a space 11 open up and down, and the shock absorbing member 20 is embedded in the space 11.

The buffer member 20 is configured in the form of a hollow pipe and the material is a synthetic rubber material in consideration of the cushioning properties. However, the buffer member 20 may be filled in the case 10 in the form of small beads, the shape of which is deformable within a range having cushioning properties while being embedded in the case 10.

The upper and lower caps 30 and 31 which hold the upper and lower sides of the cases 10 are provided.

Opposite surfaces of the upper and lower caps 30 and 31 are provided with fitting portions 32 into which the open top or bottom of the case 10 is fitted, and the upper and lower caps 30 and 31 are posts. It is divided into two each so as to be easy to assemble to 50, the fastening portion 33 for fastening the bolt 34 and the nut 35 is formed on the opposite surfaces. In addition, the upper and lower caps 30 and 31 may be integrally formed so as to be pre-plugged into the strut 50 before the strut 50 is installed on the road.

And the band 40 is provided to wrap and protect the case 10 disposed on the outer periphery of the support (50). The band 40 is formed so that a large number of small protrusions and protrusions 41 formed on the outer circumferential surface so that illegal advertisement leaflets are not attached, the band 40 is formed of the case 10 through the adhesive or a separate wire It is fixed to the outer circumferential surface.

The shock absorber configured as described above is assembled as shown in FIGS.

First, the lower cap 31 is fastened and fixed to the outer circumferential surface of the support 50 with bolts 34 and nuts 35, and a plurality of lower ends of the cases 10 are radially formed on the upper surface of the lower cap 31. Plug into the dog's fitting (32). At this time, the case 10 is a state in which the buffer member 20 is built. Thereafter, the upper cap 30 is fastened and fixed to the outer circumferential surface of the strut 50 by using the bolt 34 and the nut 35, but the open upper ends of the cases 10 are attached to the fitting portions 32 thereof. Fix it.

When the band 40 having the uneven parts 41 is wound around and fixed to the outer circumferential surface of the radially arranged case 10, a pair of shock absorbers are coupled to the support 50. In this way, a plurality of sets of shock absorbers can be coupled to the support 50 in a multi-layer, and the height of the set of shock absorbers is approximately 1 m, so that the stacking of the shock absorbers to be 2 to 3 m high from the bottom of the road is opposed to the passenger car. It reaches a height that can protect the driver in the event of a vehicle crash up to the truck.

The shock absorber according to one embodiment of the present invention, which is assembled as described above, is deformed while being distorted in the collision direction of the vehicle, thereby protecting the driver primarily while absorbing impact energy. In addition, the shock absorbing member 20 built in the case 10 is deformed while being finally crushed, and the impact force is not transmitted to the driver while the shock due to the collision of the vehicle is alleviated.

The crushed shock absorbing member 20 has a property of being elastically restored because it is a synthetic rubber material, but the case 10 is made of a metal material so once it is deformed, it is not restored to its original state. Since there is no impact on the shock absorbing property of the shock absorbing member 20 is improved.

And when the crushed case 10 and the buffer member 20 is selected and replaced, the cost is reduced compared to when replacing all, reducing the maintenance cost, and the outer peripheral surface of the case 10 can not attach illegal advertising leaflets Since the band 40 having the uneven portion 41 is wound, the road aesthetics can be improved. And since the band 40 also has a function to protect the case 10, the reliability of the shock absorber is secured.

As described above, a plurality of cases are disposed radially on the outer circumferential surface of the road post of the present invention, and the shock absorbing member may be protected because the shock absorbing member of the synthetic rubber material having a cushioning property is built in the case.

And since the case is not restored once crushed again, the repulsive force of the buffer member is prevented so that the repulsive force due to the restoration is not transmitted to the driver, so that the buffering property of the buffer member is improved, and the crushed case can be selected and replaced. Maintenance costs can be reduced when replacing them all.

In addition, the outer circumferential surface of the case is wound with a band to which the illegal advertisement leaflets are attached, thereby improving aesthetics of the road and protecting the case, thereby improving reliability of the shock absorber.
