DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a protective body is installed by placing an extension member on the entry side of a vehicle and placing a stop member and an extension member on a road by contacting the road surface. At this time, the vehicle safety protector of the present invention may be used alone or in parallel, depending on the installation environment and conditions.

[0008] If a driver makes a mistake and runs toward the vehicle security guard of the present invention, the vehicle first rides on the extension member and then collides with the stop member. When the vehicle rides on the extension member, the extension member is pressed against the road surface by the weight of the vehicle. Therefore, even if the vehicle collides with the stop member, the entire member does not slip and the stop member receives an impact at the installation position and is deformed. To block the running of the vehicle.

[0009] The vehicle safety protector of the present invention blocks the running of the vehicle without slid together with the vehicle upon collision with the vehicle, so that the stop member is deformed when the collision occurs, It is only necessary to be able to absorb the impact, and the traveling of the vehicle can be blocked at the installation position without requiring a special shape or structure. For example, a hollow body such as plastic or rubber, a hollow body with a fluid, powder or foam filled inside, or a foam body such as foamed plastic or foam rubber Can be configured.

In one embodiment of the present invention, the stop member is formed of a hollow body having a polygonal cross section so that the stop member can be manufactured at low cost, and the extension member is formed of a sheet. When not in use, the extension member is wound around the stopper member when not in use, thereby making the whole compact and easy to carry and store.

In the vehicle safety protection body of the present invention, when the extension member is in the form of a seat, the extension member is connected to the stop member by winding the extension member around the stop member, and winding one end portion and the other end portion. Even if it is done by overlapping the stop member near the ridge line closest to the road surface, the extension member is wound around the stop member, and one of the wound portions is folded back on the lower surface of the stop member, and then the other is wound. It may be done by overlapping the parts. With the latter combination, when the vehicle collides with the stop member, the stop member is deformed and not only absorbs the collision impact, but also rotates around the folded portion of the extension member, and the collision impact is also caused by the rotation. Due to the mitigation, vehicle damage and occupant injuries can be reduced.

[0012] In the vehicle safety protection body of the present invention, the extension member may include a projection on the surface opposite to the surface facing the road surface, the projection providing vibration to the vehicle.
When the vehicle rides on the extension member, the driver can be informed of the danger by the vibration and the vehicle can be braked, so that the damage to the accident vehicle and the occurrence of injury to the occupant can be further reduced.

[0013] Furthermore, the extension member may be provided with a non-slip on a surface facing the road surface, so that
Sliding of the security protection body can be more reliably eliminated.

An embodiment of the vehicle safety protector of the present invention will be described below with reference to the drawings.

The vehicle safety protector is shown in FIGS.
As shown in FIG. 1, a stop member 11 is placed on the road surface 10 and blocks the running of the vehicle when the vehicle collides, and an extension member 12 is placed on the road surface 10 and is stepped on by the vehicle when the vehicle collides. Signs 13 are provided on both the front face 14 and the side face 15 of the security guard.

This is done by arranging them on the road surface 10 in a parallel manner. At this time, the unevenness 24 on the lower surface of the extension member 12 prevents the whole from slipping, so that the installed state can be always maintained.

When the vehicle makes an error in driving and travels toward the vehicle security protector, the vehicle first moves to the extension member 1.
2 and then collides with the stop member 11. Also in this case, when the front wheel of the vehicle rides on the extension member 12, the extension member 12 is pressed against the road surface 10 by the weight of the vehicle, the whole does not slip, the stopper member 11 is deformed without being flipped off, and the impact is absorbed. The vehicle is blocked at the installation position. However, the stop member 11 rotates prior to the deformation to reduce the collision impact. That is, the stopping member 1
1, when the vehicle collides, as shown in FIG.
First, the extension member 12 is rotated around the folded portion 12a, and the impact is released by the rotation.
When the rear surface is pressed against the road surface 10, the rotation stops, and the vehicle deforms at the stop, absorbs the collision impact, and stops the automobile 31. For this reason, even if the vehicle speed is high, the vehicle can be reliably stopped at the installation position without damaging the vehicle body and injuring the occupant. Further, in this vehicle safety protection body, when the automobile 31 rides on the extension member 12, the projection 25 causes the automobile 31 to vibrate, thereby allowing the driver to foresee a danger and performing the braking operation more quickly. Collisions are made at the lowest possible speed.

After use, the extension member 12 is wound around the stop member 11 as shown in FIG. By doing so, the entire vehicle security protector has the same size as the stop member 11, similarly to the vehicle security protector described with reference to FIGS. 1 to 8, and furthermore, closes each other. It can be stacked and transported and stored easily.
