Abstract

PURPOSE:To provide a vehicle collision buffer body easy to restore even when receiving shock due to collision of a vehicle and excellent in appearance. CONSTITUTION:A buffer body main body 1 is formed by combining a large number of synthetic resin made buffer cones 2. The buffer cone 2 is made into a hollow bar having a tapered outer surface, its axial direction is made to correspond with the longitudinal direction of the buffer body main body 1 and a plural number of the buffer cones connected by way of inserting small diametrical end parts of other buffer cones into their large diametrical end parts are provided in parallel in a plural number of rows in the vertical and horizontal directions. By applying a heat insulating cover 5 on a drum part of the buffer body main body 1 and a front cover 6 on its front surface, they are made in a rectangular parallelopiped shape roughly.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle collision buffer installed at the tip of a road junction, a median strip, a safety zone or the like.

[0002]

2. Description of the Related Art Conventionally, as this type of vehicle collision buffer,
For example, as shown in FIG. 5 (a), a cylindrical drum 11 made of synthetic resin having a buffer water bag inserted therein is used, and a plurality of the drums 11 are installed at the tip of the concrete separation belt 10, or as shown in FIG. Sandbag 1 filled with sand as shown in (b)
2 is used, and a plurality of sand bags 12 are stacked on the tip of the separation belt 10. In addition, as shown in FIG.
It is also known that a guard guard 13 made of steel is provided at the tip of 0 and a plurality of cushioning bodies 14 made of urethane resin are provided in the fence.

However, such a conventional one is apt to be deformed or damaged by the impact of a vehicle collision, and it is difficult to restore it to a reusable state. There was a problem that all had to be replaced with new ones. Further, there is a problem that it gives a driver a visual oppressive feeling and is not said to be excellent in terms of scenery.

An object of the present invention is to provide a vehicle collision cushioning body that solves the above conventional problems.

[0005]

In order to solve the above-mentioned problems, the present invention covers the buffer body with a synthetic resin cover to form a substantially rectangular parallelepiped shape so as not to give a feeling of pressure to the vehicle driver and to prevent the landscape from being impaired. The shock-absorbing body is formed of a combination of a large number of shock-absorbing cones so that deformation and damage due to a vehicle collision can be suppressed and the shock-absorbing body can be reused even when it receives a shock.

That is, the vehicle collision buffer of the present invention has a substantially rectangular parallelepiped shape in which the buffer body is covered with a synthetic resin cover, and the buffer body is formed by combining a number of synthetic resin buffer cones. Is a hollow rod,
The outer diameter is gradually reduced along the length direction and has a tapered outer surface, and its axial direction corresponds to the front-back direction of the buffer body, and the small diameter end of another buffer cone is inserted into the large diameter end. By doing so, a plurality of connected pieces are held in parallel in a plurality of rows in the vertical and horizontal directions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, A is a vehicle collision buffer of the present invention, and as shown in FIG. 1, it is formed by covering the body of the buffer body 1 with a heat insulating cover 5 and the front surface with a front cover 6, and is generally in the shape of a rectangular parallelepiped. Has been made.

The cushioning body 1 is formed by combining a number of cushioning cones 2 that absorb the impact of a vehicle collision. The buffer cone 2 is made of a thermoplastic resin such as polyvinyl chloride, polyethylene, polystyrene or the like. Particularly, it is preferable that the buffer cone 2 is made of a recycled synthetic resin because the resin which becomes industrial waste can be effectively used. The buffer cone 2 is in the shape of a hollow round bar or a rectangular bar, and has an outer diameter that is gradually reduced along the length direction and has a tapered outer surface.

As shown in FIG. 2, the buffer cone 2 has its axial direction corresponding to the front-back direction of the buffer body 1, and the large-diameter end portion of the buffer cone 2 is inserted with the small-diameter end portion of the other buffer cone 2. A plurality of connected ones are provided in parallel in a plurality of columns in the vertical and horizontal directions. As shown in FIG. 3, the plurality of buffer cones 2 connected in the axial direction are held in parallel by inserting their rear end portions into the concave portions of the urethane foam base 4 through the metal perforated guide plate 3. .

A plurality of buffer cones 2 connected in the axial direction are arranged side by side in the vertical and horizontal directions. As shown in FIG. 2, the large-diameter end portion is located on the front side of the buffer body 1. Among the above-mentioned products, the one having the small-diameter end portion located on the front surface side of the buffer body 1 is arranged. In addition, in the case of FIG. 2, three buffer cones 2 connected in the axial direction are arranged in parallel, but the number of buffer cones 2 is not limited to this.

The heat insulating cover 5 is made of synthetic resin, has a reverse groove shape in cross section, and covers the body of the buffer body 1. The heat insulating cover 5 is filled with an antifreeze liquid in order to reduce the decrease in hardness of the buffer cone 2 due to the decrease in temperature. The heat insulating cover 5 may also be made of recycled synthetic resin, like the buffer cone 2.

The front cover 6 is made of a foamed synthetic resin such as urethane resin, covers the front surface of the buffer body 1, and is continuous with the heat insulating cover 5. On the front surface of the front cover 6, a reflector 7 for guiding the eyes at night is attached. The front cover 6 may also be made of recycled synthetic resin.

The vehicle collision buffer A of the present invention comprises a buffer body 1
The heat insulating cover 5 and the front cover 6 are covered, the metal fixed belt 8 is hung on the heat insulating cover 5, and the end anchors 9 of the fixed belt 8 are fixed and installed on the road surface. For example, the case of FIG. 4 is an example of being installed at the tip of the concrete separation band 10.

[0014]

As described in detail above, in the vehicle collision shock absorber of the present invention, the shock absorber main body is made up of a combination of a large number of synthetic resin shock absorber cones, and the shock absorber cone has its axial direction corresponding to the front-back direction of the shock absorber body. , A plurality of small diameter end portions of other cushioning cones inserted into the large diameter end portion are connected in parallel in a plurality of rows in the vertical and horizontal directions, so that they are shock-absorbed by a collision of the vehicle. Even if the body is disassembled, the buffer cone is not easily deformed or damaged, and the buffer cone can be reused.

Further, since the buffer body is covered with a synthetic resin cover to form a substantially rectangular parallelepiped shape, it does not give a visual feeling of pressure to the vehicle driver as in the conventional case, and also in view of the scenery. You can keep the beauty.
