Description

[Detailed description of the invention] The present invention is a two-wheeled toy that uses a flywheel to run independently. This invention relates to a two-wheeled toy that can be moved up and down.

In general, this type of two-wheeled toy has a casing provided between the front wheels and the rear wheels, a flywheel rotatably installed within the casing, and the inertia of the flywheel used to rotate the driving wheels. It is designed to run independently. However, in conventional two-wheeled traveling toys, the flywheel was installed offset to either the left or right of the center line of the traveling toy, resulting in unstable running, monotony, and lack of uniqueness. Ta.

The present invention has been made in view of the above points, and in particular, the rotating shaft of the flywheel is inserted into the bearing holes provided on both sides of the casing body, and
The purpose of this product is to propose a two-wheeled toy that can provide a sense of stability when riding by having a configuration that allows the mounting position to be changed vertically, and also allows the user to enjoy unique wheelie running and eccentric movements. It is something.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral A indicates a two-wheeled toy according to the present invention, and this two-wheeled toy A is configured to be able to run in the shape of a motorcycle by a handle part 1 at the front and a casing body 2 at the rear. It is something that exists.

The casing main body 2 is formed by fixing left and right side plates 3, 3 made of synthetic resin at a constant interval using spacing supports 4, 4, and connecting grooves 5c are formed in the side plates 3, 3. Bearing holes 5a and 5b are continuously formed. 6 is the center line S of the two-wheeled vehicle running toy A provided between the above-mentioned side plates 3 and 3.
This figure shows a flywheel disposed above, and a pinion 7 is arranged in parallel with the flywheel 6, and its rotating shaft 8 is fitted into a bearing hole 5b below.

The bearing hole 5b is formed continuously with the upper bearing hole 5a via the connecting groove 5c, and the connecting groove 5c
Through holes 5d, 5d are formed on both sides. In this way, the side plates 3, 3 have the through holes 5d, 5d's worth of meat stolen, so the through holes 5d, 5d and the connecting groove 5c
The material between the connecting groove 5c has elasticity, and the width of the connecting groove 5c is variable. Therefore, the rotating shaft 8 of the flywheel 6 can be fitted into the bearing hole 5a or 5b by pushing out and sliding the connecting groove 5c. Reference numeral 9 indicates a rear wheel attached to both side plates 3, 3 via a rotating shaft 10, and a spur gear 11 is arranged in parallel to this rear wheel 9, and this spur gear 11 is connected to a pinion 12 and a flat The pinion 12 of the intermediate gear t formed in parallel with the gear 13
It is something that is meshed with. Further, the spur gear 13 connected to the intermediate gear t is meshed with a pinion 7 arranged in parallel with the flywheel 6. Reference numeral 14 denotes a handle support member attached to the top end between the two side plates 3, 3, and this handle support member 14
The handle portion 1 has a front wheel 15 pivoted downwardly.
is rotatably installed. Reference numeral 16 indicates a handle attached to the handle portion 1, and reference numerals 17 and 17 indicate mufflers formed at the bottom of the side plates 3 and 3. These mufflers 17 and 17 are formed by two divided members. and its rear muffler 1
7a and 17a are provided so as to be adjustable in the vertical direction via fixed shafts 18 and 18. 19 is a windshield body, and 20 is a sheet member.

The running toy A is constructed as described above, so to explain how to play with it, first, the rotating shaft 8 of the flywheel 6 is inserted into the lower bearing hole 5b, and the toy A is run against the running surface. Front wheel 1 of toy A
5 and the rear wheel 9 are brought into contact with each other and forcefully pushed apart, and the rotational force of the rear wheel 9 is transmitted to the flywheel 6 via the intermediate gear t, causing the flywheel 6 to rotate. Since the rotational force is maintained, the two-wheeled vehicle traveling toy A can be made to travel independently due to its inertia. In this case, the center position of the flywheel 6 is on the center line S of the two-wheeled vehicle running toy A, and is fitted into the lower bearing hole 5b, so the center of gravity is lowered and the running becomes stable. You can also enjoy the interesting appearance of the traveling toy A by changing the angle of the muffler 17.
It is also possible to turn left or turn right by changing the angle of the handle 16.

Next, the insertion position of the rotating shaft 8 of the flywheel 6 is changed to the upper bearing hole 5a, and the rear end 17a of the muffler 17 is bent upward to stand up the two-wheeled vehicle running toy A, and in this position, the above-mentioned If the flywheel 6 is given rotational inertia and pushed out, the center of gravity of the two-wheeled toy A will be lower than the center of gravity P1 of the two-wheeled toy A when the flywheel 6 is set up with the flywheel 6 attached to the lower bearing hole 5a. Since P2 moves rearward (see FIG. 5), wheelie running can be performed with the rear end 17a of the muffler 17 in contact with the running surface. In this case, since the flywheel 6 is located at the center of the running toy A, stable wheelie running can be obtained.

In the embodiment, the rear wheel 9 and the flywheel 6 are formed by meshing with each other via the intermediate gear t, but the invention is not limited to this. The structure may be such that the spur gear 11 directly arranged in parallel with the rear wheel 9 and the pinion 7 arranged in parallel with the flywheel 6 are meshed with each other. Further, the traveling toy A may be driven by a drive mechanism that uses a spring as a driving source and transmits the driving force to the rear wheels 9 via gears.

Further, the bearing holes 5a and 5b do not necessarily need to be formed continuously, as long as they are configured so that the rotary shaft 8 of the flywheel can be replaced by appropriate means.

As explained in detail above, the two-wheeled vehicle traveling toy according to the present invention has a flywheel arranged on its center line, and the rotating shaft of the flywheel is pivotally connected to the bearing holes bored on both sides of the casing body.
Moreover, since the bearing holes are formed at least in two places, upper and lower, the mounting position of the flywheel can be changed upward or downward. As a result, the position of the center of gravity of the two-wheeled vehicle toy changes up and down. When the center of gravity is low, stability is high, so you can drive in a well-balanced and stable manner. On the other hand, if you change the flywheel mounting position upward,
The center of gravity of the two-wheeled toy is not only higher, but also moves further back than when it is in the lower position. Therefore, wheelie running can be performed more easily. On the other hand, if you wheelie the toy with the flywheel in the downward position, the center of gravity will be relatively forward, so the motorcycle toy will not be able to maintain the wheelie position and will soon fall forward. Put it away.

As described above, according to the present invention, it is possible to enjoy normal two-wheeled vehicle running and wheelie running, and since the flywheel is placed on the center line of the two-wheeled toy, it is possible to stably perform the two types of running. can be done. Therefore, it is possible to make driving fun more enjoyable.
