Description

[Detailed Description of the Invention] The present invention relates to educational materials that show the situation in which a pedestrian is blown away or caught in a collision when a pedestrian collides with a moving vehicle.

It is always available in kindergartens, elementary schools, traffic safety classes, designated driving schools, etc., and allows children, attendants, Ienobu's mother, car drivers, etc. to see the moment of a car accident right in front of their eyes using a dummy doll. The purpose of this invention is to provide experimental teaching materials that will clearly demonstrate the horror of traffic accidents and make each other realize the horror of traffic accidents. explain.

The drawing is a side view of the collision test device.

This testing device consists of three parts: a rubber doll, a doll stand on which the doll is placed, and a winder that pulls the doll stand.

A rubber doll 1 is dressed with clothes and footwear 2.

As an example, a magnet is attached to the back of the footwear 2 in a school for lower grade students.

Next, the doll stand consists of a slide 3 made of synthetic resin or wood, an iron plate 4 fixed on the slide 3, and a rubber plate 5 fixed on the iron plate 4.

The width of the doll stand is narrower than the wheel spacing of an automobile, and its height is configured to be as low as possible to stabilize the doll 1.

A ring 6 is provided at the front end of the rubber plate 5, and cut holes 7 and 8 of the same size as the footwear 2 of the doll 1 are provided in the center part, and the iron plate 4 is exposed at the bottom of the cut holes 7 and 8. are doing.

One end of the paper string 9 is tied to the ring 6.

Next, the winding machine consists of a cast base 10, a support 11 located at the center of the base 10, a drum 12 with a handle attached to the upper end of the support 11, and a wire 13 whose one end is wound around the drum 12. I am admonishing you.

The drum 12 is attached to the support 11 with a frame or butterfly bolt, and there is a roller 14 at the end of the pedestal 10.
The ring attached to the other end of the wire 13 is connected to the paper string 9 through this roller 14, and the paper string 9 is tied to the ring of the wire 13.

In one embodiment, the height of the top of the support column 11 is configured to be approximately the same height as the top of the doll 1 on the doll stand.

Next, in order to use this device, a winding machine is installed at one end of the '75ζ road, on the sidewalk, etc., and the doll, which is stabilized on the doll stand by the action of footwear, cut holes, magnets, iron plates, etc., is placed on the road. The vehicle is set up, and the handle is turned to wind the wire onto the drum, that is, while the doll is walking, the vehicle advances and collides with the doll.

The impact of the collision causes the doll to be thrown off the doll stand or become entangled in the vehicle.

The impact of the collision breaks the paper string, and the wire continues to be wound around the drum, leaving the doll stand in its position and the vehicle passing and stopping.

Even if the vehicle gets caught on the doll stand, the doll stand is extremely low, so the car will step over it and proceed or stop.

Furthermore, new paper strings are attached and the same experiment is repeated over and over again.

It would be even more realistic and ideal to install another winder on the opposite sidewalk or in a safe zone so that the dolls could pass each other.

Next, regarding the effectiveness of this device, it is extremely easy to attach durable rubber dolls that can be used over and over again, using glue or adhesive to dress them in clothes that can be repaired immediately. Using a dummy doll that moves away from the doll stand in the event of a car collision and presents a situation that is almost the same as reality, children, their mothers, car drivers, etc. The effectiveness of this device is enormous because it allows you to clearly learn the moment of a car accident right in front of your eyes.
