<Structure of vehicle forced stop device>
Hereinafter, the vehicle forced stop device 10 according to the present invention will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is an overall perspective view of a vehicle forced stop device 10 according to the present invention.

  The vehicle forced stop device 10 according to the present invention is mounted on the base portion 20, the vehicle stop portion 30 erected on the base portion 20, and the vehicle stop portion 30 via the connection member 50 as shown in FIG. And a vehicle ride-up unit 40. And, in order to improve storability, it can be folded. That is, the vehicle riding-up unit 40 extends with respect to the vehicle stopping unit 30 in the road surface direction (diagonally forward) and is fixed at a fixed position (fixed position in use: see FIG. 1), the vehicle stopping unit 30 and the vehicle It is provided so as to be movable in position between the folding parts (not shown) where the riding parts 40 overlap.

  The base portion 20 is a portion that exerts a vehicle stopping effect due to frictional resistance with the road surface when a rushed vehicle collides with the vehicle forced stop device 10. A rubber plate or the like is installed on the back surface of the base portion 20 (surface in contact with the road surface), and a plurality of claw members 70 are installed to further improve the frictional resistance. The vehicle stop portion 30 is erected on the base portion 20, and when the rushed vehicle collides, the front surface of the vehicle collides and receives a force in the traveling direction of the rushed vehicle. This is a part for lifting the vehicle riding portion 40 according to the principle of leverage.

  The vehicle run-up unit 40 is attached to the vehicle stop unit 30 via the connection member 50, and is a part that dives into the lower part of the rushed vehicle and a part that the front side of the run-up vehicle rides on. The vehicle compulsory stop device 10 composed of these structures is embedded in the lower part of the vehicle into which the vehicle riding part 40 provided integrally with the vehicle stopping part 30 enters, utilizing the lever principle and the frictional resistance between the road surface, It is to forcibly stop the vehicle that rushed in by mistake.

  FIG. 2 is a side view of the vehicle forced stop device 10. The vehicle forcible stop device 10 according to the present invention, as shown in FIG. 2, includes a connecting member 50 for connecting the vehicle riding portion 40 and the vehicle stopper 30, and further, at the lower end of the vehicle stopper 30. An elastic member 60 (in the embodiment, a coil spring) is disposed on the outer periphery and immediately below the both ends of the connection member 50. Here, it is a point in the present invention that an elastic member 60 (in the embodiment, a coil spring) is installed around the lower end of the vehicle stopper 30 and directly below both ends of the connection member 50.

  When the rushed vehicle rides on the vehicle riding-up unit 40, the vehicle riding-up unit 40 is pushed downward by its own weight. At this time, the elastic member 60 (in the embodiment, a coil spring) installed immediately below both ends of the connection member 50 is slowly pushed down by the action of the elastic member 60 so as to reduce the impact upon the rider. . The point of the present invention is that the elastic member 60 is installed so that the driver can stop the vehicle without being shocked so that the driver can not operate the brakes. To be able to do quick brake operation. That is, the free running distance by shortening the reaction time (The distance the vehicle traveled from when the driver felt the need to stop until the brakes actually started to work after the start of the brake operation: reaction time x Vehicle speed can be shortened.

<Stopping principle and method of use of vehicle forced stop device>
In the case of a collision with a rushed vehicle, the vehicle forced stop device 10 according to the present invention causes the vehicle riding portion 40 to dig into the lower surface of the front of the vehicle (see FIG. 2) and pushes up the front of the vehicle (see FIG. 2) The friction between the base portion 20 and the road surface, even if the vehicle that has rushed in overtakes the vehicle riding portion 40 and does not push the vehicle stopping portion 30 in order to press the base portion 20 against the road surface by its own weight. The resistance can be amplified. That is, the vehicle can be safely stopped by the frictional resistance between the vehicle and the road surface.

  Further, when a vehicle rushed in at high speed collides, the vehicle gets over the vehicle riding up portion 40 and collides with the vehicle stopping portion 30. At this time, the vehicle riding section 40 is lifted (that is, the force from the traveling method is used to lift the front wheel of the vehicle using the principle of leverage), so that the frictional resistance between the base portion 20 and the road surface can be amplified, The frictional resistance between the vehicle and the road surface can safely stop the vehicle. That is, the vehicle is surely stopped by applying the frictional resistance between the rubber plate installed on the base portion 20 and the road surface, and the frictional resistance caused by the claw member 70 scratching the road surface using the weight of the vehicle. Further, even in the case of a collision from an oblique direction, the base portion 20 which is not fixed to the road surface can flexibly change the angle so as to face in the collision direction of the vehicle, so the vehicle stopping effect is similarly obtained. .

  FIG. 3 is a view for explaining how to use the vehicle forced stop device 10. As shown in FIG. In order to ensure the safety of workers and the like in preparation for the case where a vehicle accidentally enters during lane control during road construction, etc., the vehicle forced stop device 10 according to the present invention is as shown in FIG. Install in position. That is, two forcible vehicle stop devices 10 are disposed at a distance of about 20 m from the work track (a vehicle stop distance required when a normal vehicle enters at a speed of 60 km / h is about 10 m, considering safety). It arranges side by side, and further separates about 20 m, and arranges two vehicles forced stop devices 10 side by side. At this time, the vehicle forced stop device 10 installed at a distance of about 20 m from the work truck should be installed at the center line side, and the vehicle forced stop device 10 installed another 20 m away from the work line, 3).

<Effect of vehicle forced stop device>
The vehicle forcible stop device 10 according to the present invention can prevent the rolling over of the rushed vehicle and can be safely stopped, and the stop member (iron fence, safety cone, water drum, sand bag, etc.) is repelled and scattered By doing so, secondary and incidental troubles and post-processing can be greatly reduced. Furthermore, in the present invention, by installing the elastic member 60, the driver is relieved of the impact due to the collision, and the driver can quickly perform the brake operation to stop the vehicle without receiving the impact that the brake operation can not be performed. There are things that can be done. That is, the free running distance (the distance traveled by the vehicle from when the driver of the vehicle felt the need to stop until the brake actually starts to take effect after the start of the brake operation: reaction time x vehicle speed) There is a feature that it can be shortened by making the brake effective. Then, in addition to the rubber plate, a plurality of claw members 70 are installed on the base portion 20 to increase the friction (scratch) resistance with the road surface.

  The above-described effects will be described in more detail. The vehicle forced stop device 10 is integrated with the vehicle that has entered, and is used to stop the vehicle by friction with the road surface while being moved, that is, by using the vehicle's own weight. It can be made to stop safely by adding the frictional resistance with the special rubber plate and road surface which are installed in a braking surface, and also the frictional force by claw member 70 scratching a road surface. That is, there is no large impact on the driver and secondary damage to a third party can be minimized.

  And the impact at the time of a collision can be relieved by elastic member 60. When the vehicle rides on, the vehicle riding portion 40 is pushed downward by its own weight. By installing the elastic member 60, the driver can reduce the impact caused by the collision, and can perform a quick brake operation to stop the vehicle without receiving an impact that the brake cannot be operated. is there. That is, the free running distance (the distance traveled by the vehicle: reaction time x vehicle speed from when the driver of the vehicle felt the need to stop until the brake actually starts to work after the start of the brake operation) is shortened. be able to.

  The free running distance refers to the time when the driver feels danger and sudden braking is necessary. Move the foot from the accelerator pedal (reflection time: about 0.5 seconds) and place the foot on the brake pedal (change time) 0.2 seconds), this is the distance to the point when the brake starts to work (step 0.2 seconds). The time taken to take braking measures during this period is called "reaction time (free running time)", and although there are individual differences, the average reaction time for people is usually 0.75 seconds. The free running distance is obtained by “reaction time (seconds) × vehicle speed (m / second)”. In the present invention, by reducing the impact at the time of a collision, there is almost no reaction time, and the braking can be made effective immediately, as a result of which the free running distance is to be shortened.

  In the vehicle forced stop device 10 according to the present invention, in addition to the rubber plate on the base portion 20, a plurality of claw members 70 are installed to increase the frictional resistance with the road surface. Specifically, in the case of a collision at a vehicle speed of 40 km / h, if the vehicle forced stop device 10 according to the present invention is used, an experimental result is obtained that the vehicle stops at only 4.5 m when the brake is applied. Yes. In the guidance book of traffic police practice, the formula of “approximate stop distance = square of speed / 100” is shown as the formula for approximate stop distance, which makes it possible to stop at a speed of 40 km / h. The distance can be calculated as about 16 m. Also from this, it is possible to prove the effect of the vehicle forcible stop device 10 according to the present invention.

  Moreover, the vehicle forced stop device 10 according to the present invention can be folded in a compact manner in consideration of storability and transportability. That is, as a result of folding, a compact size of 1108 mm × 600 mm × 187 mm could be realized. This size fits into the trunk of a regular car and is easy to handle not only for transportation to the installation site but also for installation on the road.
