Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a running toy that runs by rotating drive wheels using a spring unit mounted on a chassis.

[Prior Art] Conventionally, this type of traveling toy is mounted on a chassis using one spring unit as a driving source, and is driven by rotating a pair of drive wheels. The mainspring unit has a drive shaft protruding from both sides and a drive wheel attached to each protruding end.The drive shaft is rotated by the unwinding force of the built-in mainspring, and the drive wheel rotates when it touches the ground. Ta.

[Problems to be Solved] However, in the above conventional technology, the rotation that can be applied to the drive wheels from the spring unit, which is the drive source, via the drive shaft is the same for all drive wheels, and the rotation is complicated. Unless a rail or the like with a curved line is used, the player can only run in a fixed direction using linear or circular motion from start to stop, which reduces the interest of the player.

The present invention has been developed in view of the above-mentioned prior art, and it is an object of the present invention to provide a running toy that is capable of not only running in a fixed direction, but also capable of S-curve running, spin running, etc.

[Means for Solving Problems] Therefore, in the present invention, in a traveling toy that runs by rotationally driving the driving wheels by a spring unit mounted on a chassis, a pair of spring units are mounted on the chassis in parallel and detachably. Each spring unit has a drive shaft protruding from only one side, and a drive wheel is attached to each of the protruding ends of these drive shafts, thereby achieving the above purpose. It is something.

[Embodiment] Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 4.

The running toy of this embodiment is constructed by mounting a pair of spring units 23 on a chassis 1 and covering them with a car body 4.
It is in the form of a four-wheeled vehicle with front wheels 1 and 12 and front wheels 13 and 13.

Spring units 2 and 3 are spring 7, respectively.
A gear device 8 is built into the cases 5 and 6, and the gear device 8 rotates the drive shafts 9 and 10.

The drive shafts 9 and 10 are supported by the cases 5 and 6, respectively, and their shaft ends are made to protrude only to one side of the cases 5 and 6, and the other side is prevented from protruding outside the cases 5 and 6. be. Both mainspring units 2.3 are mounted in parallel on the rear wheel side of the chassis 1 with the side surfaces that do not allow the drive shafts 9 and 10 to protrude in contact with each other, and are compactly mounted on the chassis 1. . In this state, the drive shafts 9 and 10 each protrude to the opposite side of the chassis 1, and rear wheels 11 and 12 are attached to each protruding end. In addition, rear wheel 1
1 and 12 are removable, and by using rear wheels with different diameters, it is also possible to change the driving conditions.

The front end sides of the cases 5 and 6 of the mainspring units 2 and 3 are provided with square locking parts 14 and 1 that project forward.
5, thin plate-shaped locking portions 16 and 17 are formed on the rear end side and project rearward.

On the other hand, a pair of elastic locking hooks 18 and 19 are provided at a predetermined interval in the center of the chassis 1.
is erected, and a long locking member 20 with an L-shaped cross section is provided at the rear of the locking hooks 18, 19.
It is placed opposite to.

Each mainspring unit 2, 3 is connected to the locking hook 18 by inserting the locking portions 16, 17 on the rear end side into the locking member 20 and pushing the locking portions 14, 15 on the front end side toward the chassis 1. It is locked at 19. Note that by pushing and bending the locking hooks 18 and 19 forward, the mainspring units 2 and 3 can be easily attached.
can be removed.

In the figure, reference numeral 21 denotes a front wheel shaft, which is rotatably supported on the front end side of the chassis 1. This front wheel axle 21 is connected to the locking portion 14 on the front end side of both spring units 2, 3.
15, and may be held between the chassis 1 and the locking hooks 18, 19.

Next, the operation of the above traveling toy will be explained.

Here, first, the mainspring 7 of mainspring unit 2
In this case, use a spring with a large unwinding force at first, but whose unwinding force quickly becomes small, and connect the mainspring 7 of the mainspring unit 3 to the mainspring 7 of the mainspring unit 2.
A case will be explained in which the unwinding force is smaller than that of the previous one, but a constant unwinding force can be obtained continuously.

While the rear wheels 11 and 12 are in contact with the running surface, the mainsprings 7 and 7 of the mainspring units 2 and 3 are pulled backwards.
When the mainsprings 7, 7 are wound up and released, the running toy starts running due to the unwinding force of the mainsprings 7, 7.

At the beginning of running, the mainspring 7 of the mainspring unit 2 exerts a larger unwinding force than the mainspring 7 of the mainspring unit 3, so the rotational driving force of the rear wheel 11 on the mainspring unit 2 side is transferred to the rear wheel on the mainspring unit 3 side. 12, the running toy runs while turning toward the spring unit 3 side. After running for a predetermined time, the unwinding force of the mainspring 7 of the mainspring unit 2 decreases, while the mainspring 7 of the mainspring unit 3 continues to exert a nearly constant unwinding force. The rotational driving force of the wheel 12 is greater than that of the rear wheel 11 of the mainspring unit 2. Then, the running toy runs while turning in the direction of the spring unit 2, contrary to the previous movement. That is, the traveling toy performs an S-shaped travel as shown in FIG.

Next, if you use the mainspring unit 2 that has a built-in mainspring 7 that has a large and sustained unwinding force, and the mainspring unit 3 that has a built-in mainspring 7 that has a small and long-lasting unwinding force, you can create a mainspring unit 2 that always has a large unwinding force. Since the rotational driving force of the rear wheels 11 on the side is strong, the vehicle rotates in a circular motion.

Furthermore, when the spring units 2 and 3 are installed in which the rotation directions of the rear wheels 11 and 12 are reversed, the traveling toy runs in a spin manner.

Of course, if spring units 2 and 3 containing springs 7 and 7 with the same unwinding force are installed, the machine will run in a straight line as before.

In each of the above examples, the mainsprings 7 with different rewinding forces were used to create various running conditions by changing the rotational driving force of the rear wheels 11 and 12. It is also possible to perform a similar operation.

Further, according to the above embodiment, the explanation has been made using the rear wheels as the driving wheels, but it goes without saying that the front wheels may be used as the driving wheels.

Furthermore, according to the embodiment described above, the locking hooks 18,
19 are shown as a pair, but they may be formed into a long shape and integrated. Further, according to the above embodiment, the locking member 20 was described as an elongated integral piece, but
A pair may be provided so that the locking portions 16 and 17 of the mainspring units 2 and 3 are respectively locked.

[Effects of the invention] As described above, the traveling toy according to the invention has a configuration in which a pair of spring units are arranged in parallel, and a drive shaft is protruded from each spring unit only on one side, and a drive wheel is attached. By using spring units with different driving forces, it is possible to apply different rotational driving forces to each pair of drive wheels, and therefore it is possible to easily realize running conditions such as S-curve running and spin running, which were difficult to achieve in the past. This has the great effect of providing a traveling toy that is even more fun to play with.

Moreover, since we have adopted a structure in which the spring unit can be attached and removed, it is possible to change the combination of spring units with different driving forces as desired, and this allows for the above-mentioned S-curve running, spin running, etc. It is now possible to change the size and direction of these travel trajectories, as well as to travel in a straight line or in rotation.
Various running conditions desired by the player can be obtained with one toy.
