Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a drive unit for driving a traveling toy while emitting sparks, and in particular, to a drive unit for a traveling toy that can vary the manner in which sparks are radiated. Regarding.

[Conventional technology and problems]

Drive units that make running toys run while emitting sparks are more interesting than drive units that only make them run, so they are often used in monster toys, robot toys, combat toys, and the like. However, the conventional drive unit that causes a traveling toy to become a traveling toy while emitting sparks has a problem in that the manner in which the sparks are radiated is uniform and does not vary much.

[Means for solving problems]

The present invention was developed in view of the above problems, and includes a file portion formed on the outer periphery of the flywheel that serves as the power source for the drive unit, and a file portion that moves in a circle along the outer periphery of the flywheel, and a predetermined position. A plurality of flint storage members, which can be stopped at certain positions, are rotatably mounted on the same axis as the flywheel. By configuring it in this way, it is possible to emit sparks from multiple arbitrary positions, and it is also possible to emit a large amount of sparks from any one arbitrary point, allowing for a wide variety of spark emission modes. It's made for you to enjoy.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 is a cross-sectional side view, FIG. 2 is a cross-sectional plan view of the main part, and FIGS. 3 and 4 are diagrams of spark radiation.

In the drawings, reference numeral 1 denotes a case body in which two plate-like members are arranged parallel to each other at appropriate intervals and fixed with pillars. A flywheel 2 is rotatably supported at the rear of the case body 1 by a flywheel shaft 2a. This flywheel 2 has a file portion 3 formed on its outer peripheral surface, and a gear 4 formed integrally with the flywheel shaft 2a on one side.

Reference numeral 5 denotes a drive wheel, which is rotatably supported by a shaft 5a so that a part of the front and lower end of the case body 1 is exposed from the lower edge of the case body 1. Further, on one side of the drive wheel 5, a gear 6 is provided which is formed integrally with the shaft 5a and whose outer diameter is smaller than the outer diameter of the drive wheel 5. This gear 6 is linked to the gear 4 via an intermediate gear 7 supported on the case body 1 by a shaft 7a. Therefore, the rotation of the drive wheel 5 is transmitted to the flywheel 2 as an urging force. In addition, as a transmission means between the flywheel 2 and the drive wheel 5, a pulley, a belt, etc. can also be used.

Reference numeral 8 denotes locking holes, which are continuously provided in large numbers on the circumference of the upper surface of the case body 1 with the flywheel shaft 2a as the center. This locking hole 8 is used to position a flint storage member 10, which will be described later.

Note that a two-wheeled rear wheel 9 having running wheels on both sides is provided at the rear of the case body 1. Therefore, the drive unit as a whole is of a tricycle type.

In this embodiment, two flint storage members 10 are provided, each of which is configured as follows. That is, the flint storage member 10 has an inverted U-shaped frame 1
1 is provided, and this frame body 11 is placed on the upper part of the case body 1,
While loosely fitting the case body 1 between them,
Both ends of the frame are rotatably attached to the flywheel shaft 2a. Of the two housing members 10, the frame 11 of one is more μ than the frame 11 of the other.
The frame body 11 of each
The tips of the two are overlapped so that they can be attached to the flywheel shaft 2a.

Reference numeral 12 denotes a locking portion protruding from the inner side of the frame 11 at a position corresponding to the locking hole 8 provided in the case body 1 . Therefore, both of these frames 11 can rotate the upper part of the case body 1 around the flywheel shaft 2a and can be fixed and positioned at any desired position.

Further, a cylinder 13 is attached to the center of the upper surface of the frame 11 of the two housing members 10, respectively, facing the file part 3 of the flywheel 2.
A flint stone 14 is dropped into the interior of 3. Therefore, the lower surface of the flint 14 comes into contact with the file portion 3 of the flywheel 2 due to its own weight, and when the flywheel 2 rotates, the contact occurs to the extent that the rotational force of the flywheel 2 is not impaired and sparks are generated. do.

Incidentally, the flint 14 can also be housed in the cylindrical body using a weak spring or the like. In this way, it is also possible to position the flint 14 below the flywheel 2.

In the drive unit of the embodiment configured as described above, the two flint storage members 10 are rotated, respectively, and the locking portion 12 of the frame body 11 is locked with the locking hole 8 of the case body 1 at an arbitrary position. to adjust the spark radiation pattern. For example, as shown in FIG. 3, when two housing members 10 are fixed at separate positions, sparks are emitted from two different locations. Further, as shown in FIG. 4, when two housing members 10 are fixed adjacently, the sparks from the two flint stones 14 are combined and emitted in a larger amount than at one location.

The drive unit for a traveling toy of the present invention can be attached to and used in various traveling toys such as monster toys, robot toys, and combat toys. In this case, the spark emitting part of each toy main body is made movable, and the spark emitting part and the flint storage member 10 are connected, and by moving the spark emitting part, the storage member 10 is rotated at the same time, and its position is It may be possible to adjust the spark emitting part together with the spark emitting part.

Furthermore, the number of spark accommodating members 10 is not limited to two, and it is of course possible to attach three or more. Further, the drive unit may be of the tricycle type as in the above embodiment, or may be of a vertical type without running wheels.

[Effect of idea]

According to the present invention having the above configuration, it is possible to emit sparks from a plurality of different places or to emit a large amount of sparks, and enjoy various spark emission modes, making it possible to play with traveling toys. It can be made more varied and more interesting.
