Description

[Detailed description of the invention] This invention relates to a Yajirobee toy that rotates and swings on a swinging support. Conventionally, a plurality of balancers are inserted and fixed at an appropriate opening angle into a swinging center body that has a rotation center support shaft and a protruding balancer insertion protrusion, and the swinging center body with the balancer is attached to the upper end of the swinging support. Yajirobee toys are known that are used by being placed on a table so that they can be rotated and swung;
It does not rotate on the swinging support, and it is not possible to place the rotational center on the swinging support and rotate it with the balancer removed from the rotational center, so it is not very interesting. There were flaws.

This invention was made for the purpose of eliminating the above-mentioned drawbacks of the conventional rotating body. A wheel top consisting of a flywheel that is rotatably mounted inside the main body so as to be rotatable around the center axis of rotation, a pinion that is coaxially integral with the flywheel, and a rack rod insertion hole that is penetrated at a position opposite to the pinion teeth on the outer periphery of the main body. By rotating the flywheel at high speed by inserting and pulling out an elongated rack rod,
The present invention is characterized in that rocking rotation on the rocking support and inertial rotation of the gyro top alone on the rocking support are possible.

An embodiment of this invention will be described below with reference to the drawings. In the figure, 1 is a gyroscope body, and this gyroscope body 1 has a rotation center support shaft 2 and a plurality of balancer insertion protrusions 3 protruding from its lower side. Spinning top body 4
2, a flywheel 5 rotatably mounted inside the main body so as to be rotatable around the center axis of rotation, a pinion 6 integrally coaxial with the flywheel, and a pinion tooth facing position on the outer periphery of the top main body 4 as shown in FIG. The top main body 4 includes a top lower body 4a having a rotation center support shaft 2 and a balancer insertion protrusion 3 projecting therethrough, and a rotation center support shaft 2a which is used inverted at the center of the upper surface. The spindle upper body 4b has a ring 8 for rolling over on its outer circumference, and a rack rod insertion hole 7 on its outer circumference facing the pinion 6. 9
is a swinging support body having a dish-shaped rotation support part 10 at the upper end on which the rotation center support shafts 2, 2a of the top main body 4 are placed; It consists of a pillar 12. 13 is the top body 4
A plurality of balancers are inserted into the balancer insertion protrusions 3 of the balancer and installed at an opening angle as shown in FIG. There is. 14 is inserted from the outside into the rack rod insertion hole 7 of the top body 4, meshes with the teeth of the pinion 6, and rotates the flywheel 5 at high speed via the pinion 6 by pulling it out outward. It is an elongated rack rod, and a ring-shaped finger rest 15 is provided at one end.

Then, a balancer 1 is attached to the gyroscope body 1.
3 is inserted and fixed, the above-mentioned gyroscope body 1
When the rack rod 14 is inserted into the rack rod insertion hole 7 of the top body 1 as shown in FIG. 2 and then pulled out outwardly, the rack rod 14 The flywheel 5 rotates at high speed due to the interlocking action of the rack and pinion caused by the pulling out. Therefore, in this rotating state, the balancer 13
If the gyroscope body 1 with attached is placed on the rotary support portion 10 of the swinging support 9 as shown in FIG. 1, the gyroscope body 1 will be
The balancer 13 naturally rotates inertia on the swinging support 9, and when swinging is applied to the balancer 13, the entire balancer rotates while swinging, creating an interesting movement. On the other hand, with the balancer 13 removed from the gyroscope body 1, the flywheel 5 is rotated at high speed by inserting and pulling out the rack rod 14 in the same manner as described above, and then the gyroscope body 1 is moved to the lower rotation center support shaft 2. , or upper rotation center support shaft 2
If the gyroscope body 1 is placed on the swinging support 9 with contact a, the gyroscope body 1 can be inertially rotated without the balancer 13. Of course, with the balancer 13 removed, the gyroscope top body 1 can be used as an ordinary gyroscope top on the floor, and by placing the ring 8 of the top body 4 on the floor, it can be rolled over on the floor. It is also possible to rotate and move in the state.

Since the Yajirobee toy of this invention has the above-mentioned configuration, it can be rotated interestingly on the swinging support due to the rotating action of the Yajirobee toy, without having to manually rotate it like in the conventional Yajirobee toy. In addition, with the balancer removed from the gyroscope top body, the gyroscope top body can be placed on a swinging support and rotated, making it possible to provide a highly entertaining Yajirobee toy. .
