DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dummy doll and a bicycle collision test apparatus for realistically embodying a state in which an automobile collides with a running bicycle.

[0002]

2. Description of the Related Art A stationary collision test apparatus in which a dummy doll is suspended like a swing by a rope and an automobile collides with the dummy doll is known.

[0003]

There are many accidents in which an automobile collides with a running bicycle. Many occur when infants and school children pause or fail to confirm safety, and they must tell them about the fear of the accident. For that purpose, it is necessary to realistically realize how a human body and a bicycle are damaged and how they jump when a collision occurs. Ideally, it can be easily assembled and disassembled by carrying it to a garden or an elementary school yard.

The above-mentioned conventional collision test apparatus is of a stationary type and cannot be assembled, disassembled, or carried. In addition, when it collides with a stationary dummy doll suspended with a rope like a swing, it is suspended. Only the jumping state of the dummy doll within the allowable range of the rope is realized, and there is no reality.

SUMMARY OF THE INVENTION An object of the present invention is to provide a dummy doll and a bicycle collision test apparatus which can be assembled, disassembled, and carried, and realistically embody the state when a vehicle collides with a running bicycle. It is.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a guide rail hung horizontally on a pair of left and right supports upright by a pedestal, and a guide rail capable of running on the guide rail. A bicycle suspended on a pair of guided pulleys via a hanging string that can be cut, and a dummy doll is detachably mounted on the bicycle, stretched in parallel with the guide rail, and hung along left and right supports And a pulley moving rope coupled to the pulley, wherein the bicycle comprises a urethane body frame, a rubber handle, and a urethane wheel fitted with a rubber tire. is there.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numerals 1 and 2 denote a pair of left and right supports upright by pedestals 3 and 4. The supports 1, 2 are lower supports 1a, 2a and upper supports 1b, 2 which are fastened to the lower supports 1a, 2a by bolt wing nuts 1c, 2c.
b, tension ropes 5, 6 and anchors 7, 8
This fixes the upright state.

A guide rail 9 extends between the left and right columns 1 and 2 in a horizontal direction. The guide rail 9 may be a pipe or a guide rope 9a as shown in FIG.
Any of

On the guide rail 9, a pair of pulleys 10 are guided at predetermined intervals so as to be able to run. A bicycle 14 on which a dummy doll 16 is detachably mounted is mounted on the pair of pulleys 10.
Is suspended via a suspendable suspending string 15.
The hanging string 15 that can be cut is suitably a paper string or the like having strength enough to withstand the hanging load of the bicycle 14 carrying the dummy doll 16 and to be cut by the collision load.

Further, on the lower surface of the guide rail 9, there is provided a pulley moving rope 11 which is connected to the pulley 10 and stretched in parallel. This pulley moving rope 11
Is a pulley 1 with its left and right attached to columns 1 and 2
It is hung down along the columns 1 and 2 via the columns 2 and 13, and the hanging portions 11a and 11b are gripped and pulled.

As shown in FIGS. 3 and 4, the bicycle 14 comprises a body frame 14a made of urethane material, a handle 14f made of rubber material, and front wheels 14b and rear wheels 14c made of urethane material equipped with rubber tires 14d and 14e. ing.

As shown in FIGS. 3 and 4, means for detachably mounting the dummy doll 16 on the bicycle 14 is provided by attaching both hands, both feet and buttocks of the dummy doll 16 to the bicycle 14 as shown in FIGS.
, The touch-close type fasteners 17a, 17b,
At 17c, joining and separation are possible.

Since the present invention is constructed as described above, the columns 1 and 2 and the guide rail 9 are disassembled and carried to a kindergarten or a schoolyard of an elementary school.
6 and anchors 7 and 8, and a dummy doll 16
The preparation is completed by suspending the bicycle 14 on which the bicycle is mounted in balance with the suspension string 15 hanging from the pulley 10.

Thereafter, the vehicle is started toward the bicycle 14, and at the same time, the hanging portion 11 of the pulley moving rope 11 is moved.
The bicycle 14 carrying the dummy 16 is moved to the left or right via the pulley 10 at an appropriate speed by gripping the a or 11b and pulling it, and the automobile is caused to collide with the bicycle.

A bicycle 1 on which a car carries a dummy doll 16
4, the hanging string 15 is cut, the dummy doll 16 is separated from the bicycle 14, and both the bicycle 14 and the dummy doll 16 jump.

At this time, the bicycle 14 on which the dummy 16 is mounted is moved leftward or rightward, and the traveling speed of the vehicle, the traveling speed of the automobile,
Alternatively, the dummy doll 16 and the bicycle 1 depend on the collision direction of the automobile with the bicycle 14 on which the dummy doll 16 is mounted.
4, the dummy doll 16 and the bicycle 14 are separated from each other and jump. Therefore, the dummy doll 16 and the bicycle 14 are thrown onto the hood of a car or a windshield or thrown onto a road surface. Thus, a state where a car collides with a running bicycle is realistically embodied.

[0017] Therefore, if a child or a school child is temporarily stopped or neglecting to confirm safety, the fear of the accident can be taught in a realistic manner, which is useful for traffic safety education.

The bicycle 14 as well as the dummy doll 16 is composed of a body frame 14a made of urethane material, a handle 14f made of rubber material, and front wheels 14b and rear wheels 14c made of urethane material equipped with rubber tires 14d and 14e. Therefore, even if the vehicle collides, the bicycle 14 is not damaged and can be used repeatedly with the dummy doll 16, and the vehicle is not damaged or damaged.

[0019]

As described above, according to the dummy doll and the bicycle collision test apparatus of the present invention, it is possible to assemble, disassemble, and carry the vehicle. In particular, it has the advantage that infants and school children can be taught in real time about the dangers of accidents caused by neglecting temporary stoppages and safety checks, and used for traffic safety education.
