Description

  The present invention relates to a shock absorber for a vehicle that is installed in front of a road construction site or the like and prevents entry of a vehicle, and more particularly, to a shock absorber for a vehicle that is easy to handle due to weight reduction.

  On road construction sites, etc., on the road surface where vehicles in front of or around the construction site should not enter to prevent traffic vehicles from entering the construction site and contacting or colliding with construction personnel. A vehicle shock absorber is used to prevent the vehicle from entering the vehicle.

As a conventional technique as described above, a shock absorber for a vehicle is configured by a shock absorber body that can buffer an impact when a vehicle collides, and an extension member that is coupled to the main body and extends on the road surface. When trying to enter the site, the vehicle collides with the buffer body and prevents the vehicle from entering, and at the time of the collision, the buffer body flips off using the fact that the vehicle is on the extension member. What is not made known is known. The following Patent Documents 1 to 3 show an example.

  As described above, the impact shock absorber for a vehicle according to the prior art can stop a vehicle that is about to enter a construction site without blowing off the shock absorber body. It is considered that a heavy object is necessary to achieve, for example, in Patent Document 1, a foamed chip made of foamed urethane or foamed rubber is crushed and solidified with a binder is used. For this reason, the weight was about 28 kg, and it was difficult for one worker to carry.

  However, at the construction site, there is a limit to the number of workers and the work time, so it may be difficult to forcibly carry it by one person, holding the extension member by hand and dragging the buffer body together to damage the buffer body or the extension member. there were.

  In addition, since the shock absorber body is large in size and has a large structure, a large space is required when storing it in the field office, and it is difficult to secure a storage place. There is a problem of becoming.

  The present invention provides a vehicle shock absorber that improves the above-described problems of the prior art, reduces the weight of the shock absorber body, and has a desired vehicle intrusion prevention function despite the weight reduction. The purpose is to do.

  In addition, the present invention provides a vehicle shock absorber capable of assembling the light-weighted shock absorber body as described above at a construction site and saving space during product transportation and storage. For the purpose.

  In order to achieve the above object, the present invention provides a vehicle shock absorber comprising a polygonal shock absorber main body capable of absorbing shocks, and an extension member attached to the shock absorber main body and extending along the road surface. In the shock absorber, the shock absorber main body is provided with a plurality of plate-like parts obtained by cutting the resin plate into a desired cross-sectional shape, and the peripheries of the plate-like parts are held at equal intervals and in the desired width direction. It is constituted by a cross-like assembly with a plate-like coupling component that integrally couples a plurality of plate-like components, and its outer surface is covered with at least one cover as necessary.

  As described above, the present invention provides a vehicle shock absorber comprising a polygonal shock absorber main body capable of absorbing an impact, and an extension member attached to the shock absorber main body and extending along the road surface. A plurality of plate-like parts obtained by cutting the buffer body into a desired cross-sectional shape of the resin plate, and a plurality of plates extending in the desired width direction while holding the periphery of each plate-like part at equal intervals Since it is composed of a cross-beam assembly with a plate-like coupling part that integrally joins the shaped parts, it is possible to carry and carry out installation work by one person with the weight of the buffer body being kept at, for example, 10 kg or less, In addition, since the buffer body can be assembled and disassembled at the construction site, it is possible to save space during product transportation and storage, thereby reducing costs.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
1A and 1B are diagrams for explaining the outline of a vehicle shock absorber according to the present invention. FIG. 1A is a perspective view, and FIG. It is sectional drawing.

  As shown in these drawings, the impact shock absorber for a vehicle according to the present invention has a polygonal column buffer body 1 such as a triangular prism, and one end wrapped around the body 1 and fixed, and the other end is extended along the road surface. When the vehicle enters from the right direction in FIG. 1A, the intruding vehicle collides with the buffer body 1 while riding on the extension member 2, and the front side of the vehicle body is the buffer body 1. By climbing up, the vehicle is prevented from entering, and the vehicle is prevented from being flipped by colliding with the buffer body while the invading vehicle rides on the extension member.

  As described above, as shown in the above-mentioned patent document, it is well known that a vehicle impact shock absorber is composed of a shock absorber body and an extension member.

  In the present invention, the polygonal buffer body 1 is constituted by an assembly that is assembled in a cross-beam shape using a resin plate such as plastic corrugated cardboard as a raw material.

  2 and 3 show an example. That is, this example shows an example applied to a triangular prism-shaped buffer, for example, nine plate-like parts 11 cut into a regular triangle having a height of about 1 m using, for example, a plastic cardboard having a thickness of 5 mm, Six pieces of connecting parts 12 having a rectangular shape with a length of about 80 cm are prepared for integrally joining the nine plate-like parts at regular intervals. Then, a pair of slits 111 for coupling with the coupling component is formed around each of the triangular plate-shaped components, and a certain interval is formed on one side edge of the coupling component 12 with each of the plate-shaped components. A slit 121 for coupling is formed, the slit 111 and the slit 121 are engaged with each other in a state where the plate-shaped component 11 and the coupling component 12 are orthogonal to each other, and the coupling component 12 is pushed between the plate-shaped components 11. And the connecting component are assembled in a cross-beam shape, and the resin plate assembly 13 thus obtained is covered with a cover 14 as shown in FIG. Combined to make the buffer body. The cover 14 has a shape that can cover the entire surface of the resin plate assembly 13, and one side surface of the cover 14 can be opened and closed by a fastener 15 as necessary.

  As described above, the present invention provides a shock absorber for a vehicle comprising a polygonal buffer body and an extension member attached to one end of the buffer body and extending along the road surface. Since the main body is composed of an assembly that is assembled in a cross-beam shape using a plastic cardboard or other resin plate as a raw material, the weight of the buffer body can be reduced to 10 kg or less. It has been confirmed that it is possible to perform the installation work and to exhibit the desired vehicle intrusion prevention function despite its weight reduction. In other words, the present invention reduces the weight of the shock absorber body that is collided when the vehicle rides on the extension member, so that the weight reduction does not significantly affect the original intrusion prevention function of the vehicle. As a result of the experiment, it was confirmed that the passenger car can absorb the impact force at a speed of 20 km / h and assist the vehicle stop.

FIG. 1 is an explanatory view showing an outline of a vehicle shock absorber according to the present invention, in which (a) is a perspective view and (b) is a cross-sectional view taken along the line AA of (a). 2A and 2B are explanatory views of the buffer body, wherein FIG. 2A is a front view of the plate-shaped component, FIG. 2B is a front view of the coupling component, and FIG. 2C is an explanatory diagram illustrating an assembled state of the plate-shaped component and the coupling component. It is. It is a perspective view which shows the relationship between a resin board assembly and a cover.
