[29] The support tank 22 is one-piece molded or rotation-molded with a specific polyethylene (PE) based material, thereby not being broken or torn, absorbing impact energy due to its buffering action and shearing stress when a vehicle collides with the

front side of the head tank, returning the collided vehicle to the original driving roadway due to its cushioning and returning functions when a vehicle collides at its side with the front portion. The support tanks 22 are arranged in a multistage at the rear side of the head tank 12 and fixed to ground.

[30] The support tank 22 is formed therein with a space 28 to store a number of impact absorbers 21 in a movable state in the space 28 so that impact energy occurring when a vehicle collides with the front portion of the head tank may be absorbed, and the support tank 22 is formed at an upper portion of the front side thereof with a hole 23 for putting the impact absorber 21 therein. The impact absorber 21 is made of rubber chip having a constant weight and the rubber chip is made of waste tires to reuse the tire.

[31] The front end of the upper portion of the support tank 22 may be formed with a coupling protrusion 25 in a lengthwise direction to be coupled to another tank, a rear portion of the coupling protrusion 25 may be formed of a cover 24 in an arc shape larger than the width of the tank and the rear end thereof is protruded backward, and a lower portion of the rear end of the cover 24 may be formed with a coupling projection groove 26 in a lengthwise direction to be coupled with another tank. The support tank 22 is formed at the lower portion thereof with paths 29 for installing rail (not shown) or wire (not shown) therein.

[32] FIG. 5 is a perspective view of an impact absorbing apparatus coupled to the tank apparatus for the impact absorbing apparatus according to an embodiment of the present invention; and FIG. 6 is an application view of an impact absorbing apparatus applied to a tank apparatus for an impact absorbing apparatus according to an exemplary embodiment of the present invention.

[33] As shown in FIGs. 5 and 6, according to the embodiment of the present invention, the impact absorbing apparatus applied with the tank apparatus for an impact absorbing apparatus comprises a head tank 12 installed in the front portion of the impact absorbing apparatus, support tanks 22 coupled with the rear end of the head tank 12 in a multistage, side guide panels 30 installed at a side of the support tank 22, a rear fixing member 31 being fixed to ground at a rear side of the support tank 22, a supporting frame 32 being fixed between the support tank 22 and the rear fixing member 31, and fixing pins 33 inserted into ground at a front side of the head tank 12. The upper portion of the head tank 12 is formed with a cover 14 in an arc shape larger than the width of the tank to cover the side guide panel 30. . The upper portion of the support tank 22 is formed with a cover 24 in an arc shape larger than the width of the tank to cover the side guide panel 30.

[34] The action of the tank apparatus for the impact absorbing apparatus according to embodiments of the present invention will now described as follows.

[35] First, where the impact absorbing apparatus, as shown in FIG. 5, is installed at interchange junctions of motorways, inlets of subways or tunnels, bridge posts, junctions of highways, the head tank 12 is pushed backward when the front side of the impact absorbing apparatus, that is, the front side of the head tank 12 collides with a vehicle as shown in FIG. 6, at the same time, the sandbags of the impact absorber 11 filled in the head tank 12 move in a front direction within the head tank 12. In such a way, the movement of the sandbags as the impact absorber 11 allows the impact energy applied to the head tank 12 to be absorbed first. At this time, as the support tank 22 that is arranged at the rear side of the head tank 12 in a multistage is also pushed backward in order at the same time of the backward movement of the head tank 12, the rubber chips as the impact absorber 21 filled in the support tank 22 flow forward in the support tank 22. Such flowage of the rubber chips as the impact absorber 21 allows the impact energy applied to the support tank 22 to be absorbed secondary.

[36] In addition, while the support tanks 22 are pushed backward, because the side-guide panels 30 that are installed at both sides of the support tank 22 is formed of multilayers in a multistage, the side guide panels 30 are also pushed backward due to the impact force transferred to the panels when a vehicle collides with the front side of the head tank, and breaking members disposed at the coupling points of the side guide panels 30 formed in a multistage are broken to generate shear stress to thereby absorbing the impact energy third.

[37] In such a way, as the head tank 12, support tank 22, and side guide panel 30 serve to absorb the impact energy, the speed of the collided vehicle decreases rapidly to stop the vehicle, thereby preventing the secondary traffic accidents such as vehicle s crash or vehicle s center line invasion. A this time, the head tank 12 and the support tank 22 serve to function as cushions by which the vehicle is just dented in a collision without being torn or broken, and the head tank 12 and support tank 22 may be returned to the original state after the car accident in a collision is handled. Industrial Applicability

[38] As described above, according to the present invention, the tank apparatus for an impact absorbing apparatus is easy to assemble it, serves to increase the impact absorbing efficiency, and may be one piece molded and rotation molded by employing a specific polyethylene based material thereby not being broken or torn.

[39] The forgoing embodiments are merely exemplary and are not to be construed as limiting the present invention. The present teachings can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
