Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an assembly structure for a top that rotates by itself using a built-in power source.

Technical problem to be solved In Utility Application No. 62-13225, the applicant has proposed a method for accumulating rotational energy input from the outside between an outer container and a shaft rotatably passing through the outer container. , a rotor with a built-in power unit, comprising a power unit that rotates the container by releasing rotational energy when the container is released; a grip part provided on the upper part of the shaft; and a lower part of the shaft or the lower part of the container. It grips the container and the gripping part, rotates the container and the shaft relative to each other, accumulates rotational energy in the power part, and releases the container while gripping the gripping part to allow free time for a certain period of time. We proposed a top that, after being rotated and then released from the grip, would stand up on its ground axis and rotate due to inertial motion.

In the case of such a top, in addition to having a grip part and a ground shaft like a conventional top, as mentioned above,
A container, a shaft and an integrated power section are required as additional elements. In addition, it is common practice to provide some kind of character to each frame, but if you try to provide a character to the above-mentioned frame, it will be difficult to create the character due to the presence of the above-mentioned additional elements, and the character can be exchanged in various ways. If you try, the difficulty will be even greater.

In view of the above-mentioned points, the present invention provides a self-rotating top with a built-in power section, which can be equipped with any character by improving and devising the structure of each element, and can be easily assembled. Furthermore, it is intended to allow characters to be replaced.

Next, one embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, the self-rotating top according to the present invention is divided into main components: a power unit A, a lower body B, and an upper body C.

As will be described later, the power unit A includes a container 1 containing a mainspring and a gear train linked thereto.
and a rotating shaft 2 that rotatably penetrates the container, inputs input to the mainspring via the gear train, and outputs from the mainspring.

As described in detail in the specification of the earlier application, the power unit A includes a container 1 consisting of two upper and lower circular plates 1a and 1b, as illustrated in FIGS. 6 to 9.
A gear g ₁ passes through the rotating shaft 2 and is fixed on the shaft.
Input and output gear trains g ₂ to g ₄ , g ₅ , g ₆ are rotatably held in one plate 1b by a fixed plate 3.
In addition to the mainspring ₄ , the transmission gears g ₇ and g ₈ provided on the other container 1a are meshed with g ₂ and g ₆ , respectively, and one end 4a is fixed to the other plate 1a. The end 4b is fixed to the rotating shaft 2. Numerals 5 and 6 are locking means for connecting and fixing the plates 1a and 1b.

As shown in FIG. 6, bosses 7 and 8 having a D-shaped cross section are provided around the portions of the upper and lower plates 1a and 1b through which the rotating shaft 2 passes, and which extend outward from the container 1 of the shaft 2. A flat part is formed in a part of the part.

Next, the lower body B includes a peripheral wall 10 forming a recess 9 into which the container 1 of the power unit A is fitted, and a peripheral wall 10 provided at a plurality of locations on the upper end of the peripheral wall, and an upper part of the power unit fitted in the recess. It has an elastic locking piece 11 for locking, and a grounding shaft 12 provided at the bottom.

A groove 13 having the same cross-sectional shape as the bosses 7 and 8 protruding from the container 1 is formed at the center of the bottom of the recess 9, and the grounding shaft 12 communicates with the groove for rotation. A hole 14 is provided into which the shaft 2 can be inserted.

In this way, the power unit A moves the container 1 into the recess 9.
When the tip of the shaft 2 is aligned with the hole 14 and inserted into the recess 9, and the boss 7 or 8 is recessed into the recess groove 13, until then the peripheral wall of the container has been inserted into the hole 14, as shown by the dotted line in FIG. The locking piece, which had been elastically curved outward, comes off the surrounding wall and returns to its original position.
The upper part of the container 1 is locked by the locking piece 11, and the power unit A is fixed to the lower body B so that it cannot escape and cannot rotate.

The upper body C has a peripheral wall 15 that is rotatably fitted from above to the outside of the peripheral wall of the lower body B, and has a non-circular cross-sectional shape identical to the end of the rotating shaft 2 of the power unit at the upper part. a hole 16 with a downward opening;
is fitted from above to the lower body B to which the power unit A is fitted and fixed, the upper end of the rotating shaft 2 is stopped in the hole 16, and the peripheral wall 15 is fitted to the lower body B.
By inserting the upper body C into the outer circumferential wall 10 of the lower body B until it fits therein, the upper body C is rotatably fitted to the lower body B, and is connected to the power unit A in a non-rotatable manner.

The upper body C has protrusions 17 and 18 protruding from the outer surface of the peripheral wall at approximately symmetrical positions, on which the fingertips can easily be caught.
This makes it easy to grasp the upper body and apply rotational force to it.

To play by rotating this top with the above configuration on a plane, hold the lower body B with one hand and the upper body C.
Grip each with the other hand, rotate one in a predetermined direction or both in opposite directions, and repeat this several times to rotate the rotating shaft 2 and wind up the mainspring 4 in the power unit A. Rotational energy is stored in this. After accumulating sufficient rotational energy, the ground shaft 12 is moved while holding the upper body C.
Release your hand from the lower body B while keeping it in contact with the flat surface. As a result, the mainspring 4 of the power unit A rotates in the opposite direction and releases energy, causing the container 1 and the lower body B connected thereto to rotate vigorously. Then, while rotating at a sufficiently high speed, the upper body C
When you let go of the handle, the whole unit stands up on the ground shaft 12 and rotates.

As mentioned above, it can be assembled by simply fitting and fixing the power unit A into the lower body B, fitting the upper body C thereto, and connecting it to the rotating shaft 2 of the power unit, without using a string. , it is possible to provide a top that can be easily rotated by the relative rotation of the upper body C and the lower body B. Since the lower body B and the upper body C can be easily molded from synthetic resin materials, etc., various characters can be easily provided on the outer surfaces thereof, as illustrated in FIG. By replacing one or both of the upper body C and the lower body B, you can enjoy the rotation as a different character.

Providing the projections 17 and 18 on the outer periphery of the upper body facilitates the work of accumulating rotational energy of the top. Also, when multiple pieces are rotated in close proximity at the same time, their protrusions come into contact with each other, and depending on the magnitude of the movement torque of the pieces, the contact angle of the protrusions, etc.
You can also play a fighting game, as there will be cases where one side knocks the other over.

Furthermore, since the protrusions 17 and 18 are made of a flexible material, there is no risk of injury even if the player's fingers come into contact with them during high-speed rotation, and when playing the above-mentioned fighting game, there is no risk of injury. It can also prevent damage to the

Effects of the Invention As described above, according to the present invention, in a top that incorporates a power unit and rotates on its own, the top includes a peripheral wall forming a recess into which the power unit is fitted in a non-rotatable manner, and a recess provided on the peripheral wall, a lower body having a grounding shaft and an elastic locking piece that locks the upper part of the power unit fitted in the recess; Since the upper body is non-rotatably connected to the rotating shaft, it is easy to assemble and can be equipped with any character.Furthermore, by replacing either or both of the lower body and the upper body, Characters can also be changed easily.
