Description

The present invention relates to a collision damping device for mitigating the impact when a running vehicle collides.

A collision buffer device is installed near the edge of a structure such as a fence or guardrail installed on the side of a road to prevent a vehicle from directly colliding with the structure and to reduce the impact of the colliding vehicle. It has been used in the past, and various inventions have been disclosed.

For example, Patent Document 1 discloses a system that includes a shock absorber that buckles and deforms in response to an external impact to alleviate the impact, a base plate on which the shock absorber is placed, and an anchor that fixes the base plate to a road surface. A collision buffer device, wherein the anchor includes an anchor bolt that fixes the base plate, an anchor plate member that vertically supports the anchor bolt, an anchor base member that is fixed to a slab in a road surface, and the anchor base member. A collision damping device is disclosed that includes at least a coupling member that removably couples the anchor plate member and the anchor plate member.

The collision shock absorbing device shown in Patent Document 1 simplifies work such as replacing and repairing the anchors that fix the base plate on which the shock absorbing body is placed to the road surface, and prevents the impact of scattering into the shock absorbing boxes 60 arranged in parallel. A configuration in which the prevention wire 71 is passed through and connected is shown in FIGS. 1, 2, etc.
However, since the collision buffer device connects each buffer box 60 by the freely deformable anti-scattering wire 71, the deformation of the anti-scattering wire 71 is not restricted when the vehicle collides, and the road on which the vehicle is traveling There was a possibility that it would move to the other side.

The present invention provides a collision damping device in which an engaging member that engages with a damping member is unlikely to move toward the road when a vehicle collides.

In order to achieve the above object, the present invention has the following configuration.
That is, the collision damping device according to the present invention includes a plurality of shock absorbing members arranged in parallel along the vehicle traveling direction, and an engagement member that engages with each of the shock absorbing members, and the collision shock absorbing device includes A collision buffer device comprising an engagement member that restricts movement of a buffer member ,
The engaging member is arranged with its longitudinal direction facing the vehicle traveling direction, and a moving part including a front end of the engaging member where a vehicle collision is expected is provided so as to be movable rearward,
The present invention is characterized in that a storage section in which the moving section is stored is provided at the rear.

According to the collision damping device according to the present invention, since the engaging member arranged with the longitudinal direction facing the vehicle traveling direction engages with the plurality of cushioning members arranged in parallel along the vehicle traveling direction, the impact of the vehicle collision is It is possible to stably install a buffer member that alleviates the Further, a moving part including the front end of the engaging member, which is expected to be involved in a vehicle collision, is provided so as to be movable rearward, and a storage part for storing the moving part is provided at the rear, so that the engaging member can be engaged in the event of a vehicle collision. The moving portion of the member is stored in the rear storage portion, and movement of the engaging member toward the road on which the vehicle travels is suppressed.

Further, it is preferable that the storage section is formed by a hollow portion of a tubular body capable of housing the moving section, since movement of the moving section to other than the inside of the storage section is effectively restricted.

Further, it is preferable that the storage portion is formed by a hollow portion of a beam of the fence, since the collision buffer device can be easily installed near the fence.

Further, a rail-shaped base material installed on the installation surface with its longitudinal direction facing the vehicle traveling direction, and a plurality of support members that are installed upright with their lower ends engaged with this base material, and the support members are engaged with each other. If the member is provided to support the moving portion, the lower end of the supporting member may disengage from the base material in the event of a vehicle collision, so that the supporting member does not impede movement of the moving portion. This is preferable because the movement of the moving part to a place other than the storage part is effectively restricted.

According to the collision buffer device according to the present invention, when a vehicle collides, a problem in which the engaging member that engages with the buffer member moves toward the road side and comes into contact with another vehicle is unlikely to occur.

Note that the collision damping device 1 according to the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the present invention.
For example, in each of the collision damping devices 1, each shock absorbing member 6 is provided in the shape of a hollow box, but the present invention is not limited to this, and the shock absorbing device 1 may be provided in other shapes that reduce impact by deformation. For example, each buffer member 6 may be formed of a solid elastic body, or may be formed of a foamed body such as a synthetic resin.
