Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric sesame that is rotated by the power of a motor.

Tops are one of the toys that have been loved by children since ancient times, but conventional ones generally have an inverted conical bottom with a spindle (rotating shaft) running through the center. For example, after wrapping a string around the bottom, you can momentarily unwrap the string to rotate the top, or you can pinch the top end of the spindle with your fingers and turn it, or press it with both palms and turn it. It was designed to be played with.

In this way, conventional tops are played by being rotated manually, so the child's skill, personality, or emotion is accurately reflected in the state of the top's rotation and gyration.
It's a really fun toy.

However, such hand-cranked tops are difficult for young children to handle, and if they are not trained to handle them, there is a risk that the tops may fly off in unexpected directions and injure people around them (especially when spinning with a string). This was accompanied by problems such as:

The present invention aims to eliminate the above-mentioned problems with conventional tops, provide an electric top that is fun for a wide range of ages, has a high degree of safety, and can be played regardless of whether one is dexterous or clumsy with the hands. This is the purpose.

The present invention has a protrusion that serves as a fulcrum, and has a rotary motor in a body that can freely rotate around the fulcrum, a battery that serves as a driving source for the motor, and a motor that controls power supply from the battery to the motor. The electric spinning top is characterized in that it has a switch inside, and the rotational force of the motor is directly or indirectly transmitted to the body.

The present invention also provides a rotary motor in a body that has a protrusion that serves as a fulcrum and can freely rotate around the fulcrum, a battery that serves as a driving source for the motor, and a device for controlling power supply from the battery to the motor. A flywheel is attached to the rotating shaft of the motor, and the flywheel is directly rotated by the motor, and the reaction force of this rotation causes the body to rotate in the opposite direction to the flywheel. This is an electric sesame machine that is characterized by:

One embodiment of the present invention will be described with reference to FIG. 1. A battery 4 and a motor 5 are fitted vertically into a cylindrical casing 3 with a screw formed on the upper outer peripheral surface. A spindle-shaped protrusion 2, which is the center of rotation of the electric top, is screwed onto the rotating shaft 6.

On the other hand, a cylindrical retaining part 1' whose inner circumferential surface is covered with a thin plate made of hard comb protrudes from the inner center of the bowl-shaped J]14 body L that serves as the rotating base. The projection 2 is fitted into the portion l'.

Furthermore, the disc-shaped lid 12 for covering the body l is
Its central part protrudes upward, and a screw is formed on the inner circumferential surface of the protrusion to engage with a screw formed in the upper part of the casing 3, and a switch 1 is located at a position away from the protrusion.
0 is provided, said battery 4. A lid 12 is screwed and locked to the casing 3 equipped with the motor 5 and the protrusion 2 via the screw formed in the upper part of the casing 3.

The outer edge of the body 1 has a U-shaped cross section, and the outer edges of the lid 12 are inserted into this U-shaped portion so as to be spaced apart from each other.

The battery 4 and the motor 5 are electrically connected by a switch 10 via a conductive member such as a copper wire, and by turning on the switch 10, current from the battery 4 flows to the motor 5, thereby causing the protrusion 2 to rotate. ing. Since the protrusion 2 is fitted into the retaining portion 1' without slipping, it rotates at the same rotational speed as the protrusion 2.

In the figure, reference numeral 13 denotes a knob loosely fitted to the lid 12.

Note that the lid 12 may be provided with a protrusion (not shown) in the opposite direction to the protrusion 2 instead of the knob 13, so that the top can be rotated upside down relative to the state shown in FIG.

By pinching the knob 13 of the electric top constructed in this way and turning on the switch 1O while holding the top upright, the body 1 will rotate.Then, if the top is placed on a rotating table (not shown), the body 1 will rotate. The lid body 12 is erected and rotates in opposite directions, and this rotation continues until the battery 4 is exhausted.

Although the battery 5 was a disposable type, it was made rechargeable and a connector 1 was attached to the lid 12.
1 and charging via the connector 11 is very convenient.

Another embodiment of the present invention will be described with reference to FIG. 2. A protrusion 2 is provided at the lower end of a bowl-shaped body 1, that is, at the center thereof, and a cylindrical casing 3 is provided at the inner center of the body 1. It is installed protrudingly. Inside the casing 3, a battery 4 is fixed directly above the protrusion 2, and a motor 5 is fixedly provided directly above the protrusion 2 by a locking member (not shown). This battery 4 can be charged by a separately prepared rechargeable battery (not shown), and the motor 5 is provided so that its rotating shaft 6 faces in the opposite direction to the protrusion 2.

Further, a cylindrical coupling 7 made of a hard rim is connected to the rotating shaft 6, and a flywheel 8 in the shape of a hat or a disc is removably attached to this by fitting the top part to the coupling 7. has been done.

The battery 4 and the motor 5 are connected by a conductive member (not shown) such as a steel wire, and conduction/cutoff between the two can be switched by a switch (not shown) provided on the body l. The charging operation can be performed simply by inserting a terminal connected to a rechargeable battery (not shown) into a connector (not shown) provided on the body 1.

Each of the above-mentioned parts is arranged taking into account the weight of each part so that the electric top can rotate while keeping its height and stability.As shown in the figure, the outer edge of the flywheel 8 is made thicker. It is desirable to lower the center of gravity of the entire frame by attaching a hat-shaped run weight 9 to the flywheel 8. Although the battery 4 is installed horizontally in a cylindrical shape, it may also be installed vertically, and wood, plastic, or the like may be used as the material for the coupling. Any method may be used to attach the flywheel 8 to the camp ring 7, but it is preferable that the flywheel 8 can be easily replaced with flywheels of various shapes and colors, thereby increasing the enjoyment. I can do it.

To explain the manner in which the electric top constructed in this way rotates, the battery 4 is charged in advance, and the top is placed sideways on a horizontal rotating table (with the protrusion 2 in the horizontal direction).
hold. Thereafter, when the switch is turned on, current from the battery 4 flows to the motor 5, and the rotation of the motor 5 is transmitted to the flywheel 8 via the coupling 7. In this way, the flywheel 8 begins to rotate, and when you release your hand, the torso l temporarily remains sideways and rotates slowly, but immediately after that, it stands upright and the flywheel 8 rotates in almost the same place, and this... body 1 in the opposite direction
begins to rotate and continues to rotate until the battery 4 is exhausted.

When moving a spinning top like this to another location, you only need to grab one piece of the body L' By releasing the button, the flywheel 8 and the fuselage l can be returned to the upright position, and this can be continued.

Contrary to the above, when the flywheel 8f is grabbed, the torso L rotates at a rotation speed close to the sum of the flywheel 8 and the torso 10 rotations in the above case, so if you let go, only the torso L will rotate at first. He is standing upright, but for a short time (
The state returns to the inverted state as described above.

Note that even if the switch 10 is held in a fully tilted state and the switch 10 is set to ONI, the switch 10 can be rotated in the same manner as described above.

By attaching and detaching the protrusion 2' as shown by the double dotted line in FIG. 2, it is also possible to turn it upside down.

Next, in the embodiment shown in FIG. 3, the body l is formed into a cylindrical shape so that it can also be used as a casing, and the projection 2 is formed by making the lower end of the body l into a conical shape. Note that both the switch 10 and the connector 11 are provided on the body l.

Furthermore, in the embodiment shown in FIG. 4, a cylindrical or conical lid 12' is removably attached to the body 1 so as to cover the flywheel 8, a knob 13 is attached to the lid 12, and a knob 13 is attached to the body 1. The protrusion 2 on the bottom is removable.

In this example, by attaching a Futamata-shaped protrusion 2, the top can be played with "tightrope walking", and a protrusion 14 on the outer circumferential surface of the lid 12' as shown in FIG. If an annular body 15 made of, for example, a comb is removably fitted, it is possible to play by making the pieces collide with each other or flicking so-called marbles.

As described above, the electric toy of the present invention is a toy that even infants and clumsy children can easily operate, are safe, and have plenty of fun playing with. By increasing the rotational force and improving the rotational stability, it can be combined with other accessories such as those mentioned above, thereby increasing the enjoyment.Moreover, the structure is relatively simple and economical. It has practical effects such as being able to be manufactured with ease.
