## Background
CROSS REFERENCE TO RELATED APPLICATION(S)
This application is a National Phase entry of PCT Application No. PCT/KR2014/005890, filed on Jul. 2, 2014, which claims priority under 35 U.S. C. §119(e), 120 and 365(c) to Korean Patent Application No. 10-2013-0081781, filed on Jul. 11, 2013 in the Korean Intellectual Property Office, the entire disclosures of each of which are incorporated herein by reference for all purposes.
TECHNICAL FIELD
The present invention relates to a spinning top and a spinning top play device using the same, and more particularly, to a spinning top employing a gyroscope to enhance amusement at the spinning top play, and a spinning top play device using the same.
BACKGROUND ART
Typical spinning tops are made of conical wood, and have a lower end fitted with a metal ball fitted into a lower end thereof, or a screw with a semi-spherical head.
In case of the wooden spinning top, a lot of effort to machine a main body and fit the ball is required. In addition, if impact is applied to the main body from the exterior, the main body is likely to be cracked or broken. Therefore, since the main body has been recently made of synthetic resin through injection molding, spinning tops of synthetic resin which can be easily made and improve the durability are widely released.
In case of top-spinning games, there are some methods of competing with each other to run in first from a target point of 5 to 10 m in front of a start line, hitting spinning tops to topple the opponent spinning top, and so forth.
Korea Utility Model Publication No. 20-439845 discloses a spinning top including a rotor, a rotating shaft fixed to the rotor, at least one holder provided to the outside of the rotating shaft, and at least one rotation tip detachably connected to the holder.
The spinning top disclosed in the publication has a drawback in that since the rotor is exposed to the outside, if the spinning rotor directly collides with other spinning rotor in the top-spinning game, a rotation force is likely to be decreased, which cause the interest in the top-spinning game to reduce.

MODE FOR INVENTION
Hereinafter, preferred embodiments of a spinning top and a spinning top play device according to the present invention will be described in detail with reference to the accompanying drawings.
First Embodiment
FIG. 1 is a perspective view illustrating a spinning top according to the first embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating the configuration of an outer rotor of the spinning top in FIG. 1. FIG. 3 is a cross-sectional view illustrating the configuration of an auxiliary top of the spinning top in FIG. 1. FIG. 4 is a perspective view illustrating the operation of the spinning top in FIG. 1.
As illustrated in FIGS. 1 to 4, a spinning top 100 according to the first embodiment includes an outer rotor 110, an inner rotor 120, an auxiliary top 130, and a winder 140.
The outer rotor 110 is a spherical member with an accommodation space therein, and is rotated by a centrifugal force of the inner rotor 120 installed therein.
Although in the first embodiment the shape of the outer rotor 110 has been explained to have the spherical shape for the sake of easy explanation, the present invention is not limited thereto. The shape may be applied to an elliptical shape or the like.
Also, the outer rotor 110 is provided with engaging holes 111 at the center of upper and lower portions, and each engaging hole 111 has an engaging groove 11a to which the auxiliary top 130 is engaged.
The engaging groove 111a is formed in a desired protruding shape so that the auxiliary top 130 is engaged to the engaging groove 111a to transmit a rotation force of the outer rotor 110 to the auxiliary top 130. A rotation shaft 121 of the inner rotor 120 is installed in the engaging grooves 111a to transmit the centrifugal force of the inner rotor 120 to the outer rotor 110.
Also, the outer rotor 110 is provided with a plurality of winder receiving holes 113 on a side thereof to receive the winder 140. The winder 140 is meshed with the inner rotor 120 installed in the outer rotor.
The inner rotor 120 is installed in the outer rotor 110 to be able to rotate therein, and has a disc-shaped rotor 122 installed to the rotation shaft 121. The rotor 122 is rotated in the outer rotor 110 on the basis of the rotation shaft 121 so as to create the centrifugal force, which causes the spinning top 100 to spin.
Also, the inner rotor 120 has a pinion gear 123 which is installed to the rotation shaft 121 and is meshed with a rack gear 142 of the wider 140 to convert a linear motion of the winder 140 into a rotary motion, so that the rotation shaft 121 is rotated.
The auxiliary top 130 is a hemispherical member with an accommodation space therein, and a portion of the outer rotor 110 is seated in the auxiliary top 130. The auxiliary top 130 is rotated by rotation of the outer rotor 110, and has an outer rotor accommodating groove 131, an auxiliary top rotation shaft 132, and an engaging boss 133.
The outer rotor accommodating groove 131 is a hemispherical space in which the lower portion of the outer rotor 110 is seated.
The auxiliary top rotation shaft 132 protrudes in a desired length from a bottom surface of the outer rotor accommodating groove 131. When the auxiliary top 130 is rotated by the centrifugal force of the outer rotor 110, the auxiliary top 130 rotates around the auxiliary top rotation shaft 132.
The engaging boss 133 upwardly protrudes in a desired length from the bottom surface of the outer rotor accommodating groove 131, and is engaged to the outer rotor 110 which is seated in the outer rotor accommodating groove 131.
An upper portion of the engaging boss 133 is formed with a patterned portion 133a which is fitted into the engaging groove 111a of the outer rotor 110, thereby transmitting the rotation of the engaged outer rotor 110 to the auxiliary top 130.
The winder 140 provides the inner rotor 120 with the rotation force to rotate the inner rotor 120, and has a winder body 141 of a desired length, a rack gear 142 which is formed on one side of the winder body 141 and is meshed with the pinion gear 123 of the inner rotor 120, and a finger ring 143 which is provided at a distal end of the winder body 141, and is held by a user. The rotation force is applied to the inner rotor 120 by pulling the winder 140 in a horizontal direction.
The operation of the spinning top according to the first embodiment of the present invention will now be described.
If the winder body 141 is inserted into the winder receiving hole 113 of the outer rotor 110 in the state in which the user holds the finger ring of the winder 140, the pinion gear 123 of the inner rotor 120 is meshed with the rack gear 142 formed on one side of the winder body 141.
If the user pulls the winder 140 in the state in which the user holds the outer rotor 110, the rotation shaft 121 of the inner rotor 120 and the rotor 122 are rotated by the pinion gear 123.
When the outer rotor 110 is put on the ground, the rotation shaft 121 of the inner rotor 120 rubs against the engaging groove 111a of the outer rotor 110 to cause the outer rotor 110 to generate the centrifugal force, so that the outer rotor 110 is rotated.
Also, the outer rotor 110 is put in the auxiliary top 130 in such a way that the engaging boss 133 of the auxiliary top 130 is fitted into the engaging hole 111 of the outer rotor 110. After that, if the auxiliary top 130 is put on the ground in the state in which the outer rotor 110 is engaged to the auxiliary top 130, the rotation shaft 121 of the inner rotor 120 rubs against the engaging groove 111a of the outer rotor 110, and the centrifugal force is produced on the outer rotor 110, so that the outer rotor 110 and the auxiliary top 130 rotate together.
Second Embodiment
FIG. 5 is a cross-sectional view illustrating a spinning top according to the second embodiment of the present invention. FIG. 6 is a cross-sectional view illustrating the configuration of an auxiliary top of the spinning top in FIG. 5.
As illustrated in FIGS. 5 and 6, a spinning top 200 according to the second embodiment includes an outer rotor 210, an inner rotor 220, an auxiliary top 230, and a winder 140 (see FIG. 1).
The outer rotor 210 is a spherical member with an accommodation space therein, and is rotated by a centrifugal force of the inner rotor 220 installed therein.
The outer rotor 210 is provided with a rotation shaft support 211 at an inner lower portion thereof so as to rotatably support a rotation shaft 221, so that the centrifugal force of the inner rotor 220 is transmitted to the outer rotor 210. The outer rotor 210 is provided with a rotation shaft through-hole 212 at an inner upper portion thereof so as to rotatably support a portion of the rotation shaft 221 of the inner rotor 220, so that when the outer rotor 210 is turned over, a portion of the rotation shaft 221 protrudes through the rotation shaft through-hole 212.
Also, the outer rotor 210 is provided with a plurality of winder receiving holes 213 on a side thereof to receive the winder 140 (see FIG. 1). The winder 140 is meshed with the inner rotor 220 installed in the outer rotor.
The inner rotor 220 is installed in the outer rotor 210 to be able to rotate therein, and has a disc-shaped rotor 222 installed to the rotation shaft 221. The rotor 222 is rotated in the outer rotor 210 on the basis of the rotation shaft 221 so as to create the centrifugal force, which causes the spinning top 200 to spin.
One side of the rotation shaft 221 is formed with an engaging boss 221a of a desired shape, and the engaging boss 221a is engaged an engaging groove 233 of the auxiliary top 230, thereby transmitting the rotation force of the inner rotor 220 to the auxiliary top 230.
Also, the inner rotor 220 has a pinion gear 223 which is installed to the rotation shaft 221 and is meshed with a rack gear 142 (see FIG. 1) of the wider 140 (see FIG. 1) to convert a linear motion of the winder 140 into a rotary motion, so that the rotation shaft 221 is rotated.
The inner rotor 220 has a stopper 224 installed to one side of the rotation shaft 221 which is formed with the engaging boss 221a. When the outer rotor 210 is turned over, the topper 224 prevents the engaging boss 221a of the rotation shaft 221 from protruding outwardly over a desired distance from the outer rotor 210.
The auxiliary top 230 is a hemispherical member with an accommodation space therein, and a portion of the outer rotor 210 is seated in the auxiliary top 230. The auxiliary top 230 is rotated by rotation of the outer rotor 210, and has an outer rotor accommodating groove 231, an auxiliary top rotation shaft 232, and an engaging boss 233.
The outer rotor accommodating groove 231 is a hemispherical space in which the lower portion of the outer rotor 210 is seated.
The auxiliary top rotation shaft 232 protrudes in a desired length from a bottom surface of the outer rotor accommodating groove 231. When the auxiliary top 230 is rotated by the centrifugal force of the inner rotor 220, the auxiliary top 230 rotates around the auxiliary top rotation shaft 232.
The engaging groove 233 is formed on the bottom surface of the outer rotor accommodating groove 231, and is engaged to the engaging boss 221a of the rotation shaft 221 of the inner rotor 220 which is seated in the outer rotor accommodating groove 231, thereby transmitting the rotation of the engaged inner rotor 220 to the auxiliary top 230.
The operation of the spinning top 200 according to the second embodiment of the present invention will now be described.
If the winder 140 is inserted into the winder receiving hole 213 of the outer rotor 210 in the state in which the user holds the finger ring of the winder 140 (see FIG. 1), the pinion gear 223 of the inner rotor 220 is meshed with the rack gear 142 formed on one side of the winder 140.
If the user pulls the winder 140 out in the state in which the user holds the outer rotor 210, the rotation shaft 221 of the inner rotor 220 and the rotor 222 are rotated by the pinion gear 223.
When the outer rotor 210 is put on the ground, with the rotation shaft through-hole 212 facing upward, the rotation shaft 221 of the inner rotor 220 rubs against the rotation shaft support 211 of the outer rotor 210 to cause the outer rotor 210 to generate the centrifugal force, so that the outer rotor 210 is rotated.
When the outer rotor 210 is rotated together with the auxiliary top 230, the outer rotor 210 is turned over in such a way that the rotation shaft through-hole 212 faces downward, and the engaging boss 221a of the rotation shaft 221 protrudes outwardly in a desired distance through the rotation shaft through-hole 212.
When the inverted outer rotor 210 is seated in the auxiliary top 230, the protruding engaging boss 221 is engaged to the engaging groove 233 of the auxiliary top 230, and thus the outer rotor 210 are rotated together with the auxiliary top 230 by the rotation force produced by the inner rotor 220.

Referring again to FIGS. 7 to 11, the winder 500 provides the inner rotor 320 with the rotation force to rotate the inner rotor 320, and has a winder body 510 of a desired length, a rack gear 142 which is formed on one side of the winder body 510 and is inserted into the top launcher 400 through the winder receiving hole 412 to mesh with the pinion gear 420 of the top launcher 400, and a finger ring 530. If the finger ring 530 of the winder 500 is pulled out in the meshing state to convert the linear motion of the rack gear into the rotary motion, the inner rotor 320 is provided with the rotation force to be able to rotate in the outer rotor 310.
After the winder 500 is inserted in the top launcher 400 in which the spinning top 300 is installed, the winder 500 is pulled out to rotate the inner rotor 320. In this instance, if the outer rotor 310 is seated in the auxiliary top 330 by a user's hand, the rotation shaft 321 is engaged to the rotation shaft receiving portion 333 of the auxiliary top 330, and thus the outer rotor 310 and the auxiliary top 330 are rotated by the rotation force produced by the inner rotor 320.
(Spinning Top Play Device)
FIG. 15 is a perspective view illustrating a spinning top play device using the spinning top according to the present invention.
As illustrated in FIGS. 7 to 11 and FIG. 15, the spinning top play device using the spinning top according to the present invention includes the spinning top 300 and a spinning top station 600.
The spinning top 300 includes the outer rotor 310 with the receiving space therein, the inner rotor 320 which is installed in the outer rotor 310, in which the rotor 322 is rotated around the rotation shaft 321 in the outer rotor 310, and the auxiliary top 330 which is engaged to the rotation shaft 321 of the inner rotor 320 and is rotated with the inner rotor, in which a portion of the outer rotor 310 is seated.
The spinning top station 600 is configured so that a plurality of spinning tops 300 and 300′ move and collide with each other, and includes a spinning top station body 610, spinning top seats 620, and guides 630.
The spinning top station body 610 is formed with a concave slope portion 611 at a center thereof along which the spinning top 300 moves.
A plurality of spinning top seats 620 are installed along the circumference of the spinning top station body 610, and have a plurality of supports 621 protruding from the top seating parts so that the auxiliary top 330 does not fall down. Therefore, the auxiliary top 330 can be seated on the spinning top seat 620 to maintain the stable position.
The guide 630 is a semicircular groove for connecting the spinning top station body 610 and the spinning top seat 620. The bottom 350 of the auxiliary top 330 seated in the spinning top seat 620 is placed in the groove of the guide 630, and if the auxiliary top 330 seated in the spinning top seat 620 is engaged to and rotated with the outer rotor 310, the bottom 350 of the auxiliary top 330 is rotated to move along the guide 630, so that the auxiliary top is guided to the spinning top station body 610.
The operation of the spinning top play device using the spinning top according to the present invention will now be described.
After the spinning top station 600 is placed at a desired location, the auxiliary top 330 is seated on the support 621 of the spinning top seat 620. In this instance, the bottom 350 of the auxiliary top 330 is placed in the groove of the guide 630.
The user puts the engaging hole 311 of the outer rotor 310 on the pinion gear 420 of the launcher 440 in such a way that the rotation shaft 321 of the inner rotor 320 is engaged to the engaging portion 423 of the launcher 400, and then inserts the winder 500 into the launcher 400.
If the user pulls the winder 500 out, the rotation shaft 321 is rotated by the pinion gear 420 of the launcher 400, and the inner rotor 320 is rotated in the outer rotor 310.
The user separates the outer rotor 310, in which the inner rotor 320 rotates, from the launcher 400, and seats the outer rotor 310 on the auxiliary top 330 so that the outer rotor seats 332 of the auxiliary top 330 are inserted into the engaging holes 311 of the outer rotor 310. The rotation shaft 321 of the inner rotor 320 is engaged to the rotation shaft receiving portion 333 of the auxiliary top 330 to rotate the auxiliary top 330.
As the auxiliary top 330 rotates, the spinning top 300 including the outer rotor 310, the inner rotor 320, and the auxiliary top 330 rotates around the bottom 350 of the auxiliary top 330 as a fulcrum. The spinning top 300 separated from the support 621 moves along the guide 630 from the spinning top station 620 to the spinning top station body 610 by the centrifugal force of the spinning top 300, thereby playing the spinning top game at the center of the spinning top station body 610, in which some spinning tops collide with each other.
Since the rotor of the spinning top is not exposed to the outside, the rotation force of the rotor is kept for a long period of time even at the collision. Also, the connection between the outer rotor and the auxiliary top can enhance the amusement at the spinning top play. In addition, a plurality of spinning tops can be admitted to the spinning top station at the same time to collide with each other, thereby further enhancing the amusement at the spinning top play.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
In each of the drawings used in the above description, the thickness of the lines or the scale of each element is modified appropriately in order to make it recognizable. In addition, it is noted that in this embodiment some terminologies are arbitrary defined and used in view of the function thereof, and are not limited as long as they can attain the present invention since those terminologies can be varied depending upon intention of users or operators.
