Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention provides a power device equipped with a flywheel, and can be played with as a running toy such as a toy car that is normally driven by the power, and is also powered by the power device. The present invention provides a walking and running toy that can be changed into a walking toy such as a robot toy that uses the above-mentioned power to walk by switching the switching mechanism.

``Prior Art'' Some conventional traveling toys use a power device with a flywheel inside the main body, but the power device is used exclusively to drive the drive wheels and is not used for other operations. There was little to offer. On the other hand, there are doll toys that have a power device inside the main body and use the power to move both legs alternately to perform walking motions, but this power device is only used for walking motions, and the above-mentioned running toys and running toys I can't find any toys that double as that.

"Problems to be Solved by the Invention" The present invention solves the above-mentioned conventional toys by integrating the power units of a running toy and a walking toy, which have fundamentally different functions, and by arbitrarily switching between the running toy and the walking toy for play. The aim is to create a new toy that can

"Means for Solving the Problems" In order to solve the above-mentioned problems, the present invention provides a drive wheel for traveling on one output shaft of a power unit equipped with a flywheel, and a crankshaft on the other output shaft. A frame member connected to an arm swingably supported on one side of the main body is disposed near the crankshaft, and bearing portions are formed on both sides of the frame member,
The shaft member of the driven wheel is installed in the coaxial receiving part so that it can be switched between a parallel position and a perpendicular position to the driving wheel for traveling arranged on the other side of the main body, and the shaft member of the driven wheel is installed on one side of the frame member. An operating plate is provided with a long groove for linking with the crankshaft and is installed so as to be able to move toward and away from the operating plate, and a power switching mechanism for linking the long groove of the operating plate with the crankshaft in relation to the perpendicular position of the driven wheel. It is made up of.

``Example'' The present invention will be described with reference to an example shown in the figure below. 1 is a main body of a walking and running toy, and a flywheel 2 is provided in the main body 1, and two output shafts 2a and 2b are derived. It constitutes a power plant that
For example, as shown in FIG. 3, the co-power device includes a spur gear 21 that meshes with a pinion 20 formed on the rotating shaft of the flywheel 2, and a pinion 22 that is integral with the gear 21.
and one spur gear 23 that meshes with the same pinion 22.
a, a pinion 24 integral with the gear 23a, a gear 25 meshing with the pinion 24, and a gear 25
The output shaft 2a is connected to one reduction gear device consisting of a small gear 26 etc. that meshes with the pinion 22, while the other spur gear 23b meshes with the pinion 22.
and a worm gear 27 integrated with the same gear 23b,
The output shaft 2b is connected to the other reduction gear made of a small gear 28 that meshes with the same gear 27.

One output shaft 2a of the power device is led out to one side of the main body 1, and drive wheels 3 for running are provided at both ends of the output shaft 2a.
The other output shaft 2b is led out to the other side of the main body 1, and a crankshaft 4 is attached thereto.

On the other hand, on one side of the main body, a generally mouth-shaped frame member 5 connected via an arm 52 supported by a shaft 51 is swingably disposed near the crankshaft 4.

Bearing portions 5 are provided on both sides of the frame member 5 at the top and bottom, respectively.
3 to bear a substantially T-shaped shaft member 61, each coaxial member 61 rotatably supports a driven wheel 6, and the driven wheel 6 is switched from a parallel position to a perpendicular position with respect to the driving wheel 3. The coaxial member 61 is freely formed and has a locking claw 62 protruding from one side of the coaxial member 61.
In the parallel position, the locking pawl 62 can be locked to a locking member 11 protruding from the side of the main body 1.

Further, within the frame member 5, an actuation plate 7 having a long groove 71 for engaging the crankshaft 4 is disposed on the shaft 7.
2, and is normally biased toward the crankshaft 4 side by a return spring 73, while on both sides there is a power switching mechanism related to the position of the drive wheel 6, which is connected to the shaft 4. An operating piece 74 is provided protrudingly at a position facing one side of the member 61, and the coaxial member 6
1 is formed with a notch 63 corresponding to a cam member for positioning the actuating plate 7 on the crankshaft 4 side at a position perpendicular to the driven wheel 6.

Although the above-mentioned power device can energize the flywheel 2 by rotating the drive wheel 3, other energizing means may be used, such as a pull string 81.
and a winding drum 83 equipped with a return spring 82.
The energizing mechanism 8 can also be configured by a pull string including a gear 84 formed on one side thereof, and a gear 86 that engages with the gear 86 so as to be able to move toward and away from the gear via an idle gear 85, and the output shaft 8a or the like. . Such auxiliary mechanism 8
can also be constructed on one side of the main body 1, and its output shaft 8a can be linked to one side of the worm gear 27, for example.

"Operation" With the above configuration, when the driven wheel 6 is positioned parallel to the driving wheel 3 as shown in FIG. 1, the shaft member 6
One locking pawl 62 can engage with and hold the locking member 11 of the main body 1. In this position, the notch 63 of the shaft member 61 is removed from the position of the actuating piece 74, and the actuating plate 7 is pushed outward against the return spring 73 and disengaged from the crankshaft 4. When the main body 1 is pressed in this state, the flywheel 2 of the power unit is energized via the drive wheel 3, and when the flywheel 2 rotates at a high speed and the main body 1 is released, the energy storage effect causes the flywheel 2 to be energized. The wheels 3 can be driven and the main body 1 can continue to travel.

Next, as shown in FIG. 2, when the locking pawl 62 is released from the locking member 11 and the driven wheel 6 is positioned perpendicular to the driving wheel 3, the shaft member 61
The notch 63 faces the actuating piece 74, the actuating plate 7 is returned to the crankshaft 4 side by the return spring 73, and the crankshaft 4 is engaged with the long groove 71.
When the flywheel 2 of the power unit is energized in this state, the crankshaft 4 rotates with the energy storage effect, and the actuating plate 7 that engages with it and the frame member 5 that holds it are integrated with the arm 52. It swings left and right about the shaft 51 as a fulcrum. By the swinging of the frame member 5, the main body 1 is held vertically by the gyroscope effect accompanying the high speed rotation of the flywheel 2, as shown in FIG. As it stands, the rotational torque of the power unit acts to change its direction. Further, after the driven wheels 6 on both sides have touched the ground as shown in FIG. 2B, the user stands on one foot with the right driven wheel 6 as the pivot foot, as shown in FIG. In this way, the left and right driven wheels 6 alternately act as pivot legs, allowing the user to stand on one foot and change the direction of the main body 1 for walking.

"Effects of the Invention" As described above, while the direction of the driven wheel can be freely switched between a parallel position and a perpendicular position with respect to the driving wheel, the power of one output shaft of the power unit is transmitted through a power switching device related to that position. By selectively taking out the toy, the toy body can be turned into a running toy or a walking toy. This makes it possible to transform a running toy, such as a toy car, into a completely different walking toy, such as a robot toy, with a simple switch, expanding the range of play for toys equipped with this type of power device. be able to.
