Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a traveling toy equipped with a flywheel, and more specifically, the invention relates to a traveling toy equipped with a flywheel, and more specifically, it comprises a traveling toy body and a separate drive device for imparting driving force to the toy body. This is about a traveling toy.

``Prior art'' A traveling toy with a conventional flywheel power device has a crown gear on the wheel shaft, a pinion that constantly meshes with the crown gear, and a shaft connected directly to the pinion shaft or via multiple gears. It was equipped with a flywheel.

``Problem to be solved by the invention'' However, according to the conventional structure described above, in order to impart rotational energy to the flywheel, the flywheel is rotated by holding the toy body and moving the wheel by pressing it against the road surface. Because the wheels are in contact with the road, it requires a large amount of force to start, and once a certain amount of rotational force is obtained, power is transmitted from the flywheel to the wheels, so if the wheels are left in contact with the road, This had drawbacks such as placing a large burden on the power plant.

"Means for Solving the Problems" The present invention was devised in view of the drawbacks of the above-mentioned conventional type, and as means of the present invention for solving the above-mentioned problems, in a traveling toy equipped with a flywheel, It concerns a structure that meets the following requirements. That is, (a) the toy body must be provided with a rotating shaft that is slidable in the vertical direction. (b) A flywheel containing a ferromagnetic material is provided at the top of this rotating shaft, and a clutch gear is provided at the bottom. (c) When the rotating shaft is positioned downward, the clutch gear meshes with the drive gear that transmits power to the drive wheels of the traveling toy, and when the rotating shaft slides upward, the clutch gear meshes with the driving gear. It is to be canceled.

It also relates to a drive device that has the following requirements to provide driving force to the above-mentioned traveling toy, namely: (a) a ferromagnetic material that magnetically attracts the flywheel provided on the traveling toy; The rotating body shall have a (b) It has a drive mechanism that rotates this rotating body.

"Function" In the above structure, the rotating shaft of the flywheel is formed to be slidable in the vertical direction, and a clutch gear, for example, a pinion, is provided at the tip of the rotating shaft, and a crown gear is provided that meshes based on the movement of the clutch gear. Therefore, the flywheel can be pulled up using the magnetic attractive force of a ferromagnetic material such as a permanent magnet, and the flywheel can be driven by the drive device with the power transmission to the drive wheels separated. . Furthermore, when the drive device is pulled apart after the flywheel has rotated, the flywheel descends due to gravity, for example, and the pinion of the clutch gear and the crown gear mesh to automatically transmit power to the drive wheels.

``Example'' The present invention will be explained with reference to an example shown in the figure below. 1 is a main body of a traveling toy, the exterior body of the main body 1 is formed of a non-magnetic material such as synthetic resin, and the upper part is A vertical bearing 2 is formed, and a flywheel 3 is rotatably supported on the bearing 2.
It is installed to be slidable in the axial direction. This flywheel 3 is made of iron. Further, the flywheel 3 may be formed of an iron member as a core, and a permanent magnet piece may be integrally combined with the core. The upper end of the rotating shaft 4 of the flywheel 3 is formed into a pivot shape, and an annular projection 1a serving as a positioner and a spacer is formed on the upper surface of the main body 1 forming the bearing portion. A pinion 5 having a tapered portion is provided at the lower end of the rotating shaft 4, and a crown gear 6 meshes with the pinion 5 at the lowered position of the rotating shaft 4.
A spur gear 7 is integrally provided on the shaft of the crown gear 6, while a rotating shaft 9 having a pinion 8 that meshes with the spur gear 7 is supported at the bottom of the main body 1. Drive wheels 11 are attached to both sides of the rotating shaft 9. 12 is an auxiliary wheel provided at the rear end of the main body 1.

Reference numeral 13 denotes a separately formed drive device for applying driving force to the flywheel 3 of the toy main body 1, and the main body of the drive device 13 is made of a non-magnetic material such as synthetic resin. A storage section for the battery 14 is formed on one side that also serves as the handle, and the battery 14 is stored in the storage section.
A motor 16 is attached via a switch 15 connected to the motor. The lower end of the rotating shaft of the motor 16 is formed into a pivot shape, and an annular projection for positioning is formed on the lower surface of the main body forming the bearing portion. Further, a rotary body 17 having a permanent magnet piece for applying a magnetic attraction force to the flywheel 3 is provided on the rotary shaft. In this case, the rotating body 17 may be made of a non-magnetic material and an iron plate may be provided on the lower surface thereof, or alternatively, as shown in FIG. It is also possible to have a structure that combines the two.

In the above configuration, when the rotating body 17 side of the drive device 13 approaches the top surface of the main body 1 of the traveling toy, the ferromagnetic material of the flywheel 3 and the rotating body 1
7 ferromagnetic materials exert magnetic attraction to each other,
The flywheel 3 is pulled upward. In this state, the pinion 5 as a clutch gear is separated from the crown gear 6 and becomes free, and by operating the switch 15, the motor 16 is powered by the battery 14.
When the flywheel 3 is rotated, a driving force can be integrally applied to the flywheel 3 which is magnetically linked to the flywheel 3.

After applying rotational energy to the flywheel 3 in this manner, when the drive device 13 is pulled away from the top of the main body 1, magnetic attraction between the ferromagnetic material of the flywheel 3 and the ferromagnetic material of the rotating body 17 occurs. The action stops working, and the flywheel 3 falls downward due to its own weight, and the pinion 5 of the clutch gear, which is integrated with it, meshes with the crown gear 6, and the rotational force of the flywheel 3 is transferred to the pinion 5,
The information is transmitted to the wheels 11 via the crown gear 6, spur gear 7, pinion 8, rotating shaft 9, etc., and the traveling toy main body 1 automatically starts running.

``Effect of the invention'' As described above, by forming the rotating shaft of the flywheel in the main body of the traveling toy so that it can slide in the vertical direction and configuring the clutch gear that operates based on the movement, the flywheel can be rotated. It can be pulled up using the magnetic attraction force of a ferromagnetic material such as a permanent magnet piece, and in this state, the power transmission to the drive wheel side is disconnected, and a separate drive is generated with minimal mechanical loss. It can be easily driven by the device. Further, when the drive device is separated after applying driving force to the flywheel, the flywheel descends due to gravity, for example, and the clutch gear is linked to automatically transmit power to the drive wheels. This makes it possible to start the vehicle easily without requiring a large force to press the wheel against the road surface and move it to drive the flywheel, unlike the conventional type.
