Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. 119 to Japanese Patent Application No. 2017-035083, filed on Feb. 27, 2017. The contents of this application are incorporated herein by reference in their entirety.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a spinning top toy.

Description of the Related Art

As battle games using spinning top toys, by applying impact to the spinning top toys each other, there are cases in which the rotation of the spinning top toy of an opponent is stopped by the impact force; the spinning top toy of the opponent is flicked out by the impact force; or the spinning top toy of the opponent is disassembled by the impact force, etc. (see Japanese Patent No. 5959773).

For example, the spinning top toy described in Japanese Patent No. 5959773 has a body and a shaft part, and hooks of the shaft part and hooks of the body are engaged by relatively rotating the body in one direction with respect to the shaft part. When the spinning top toy collides with the spinning top toy of the opponent, the rotation of the body is temporally stopped. And on the other hand, the rotation of the shaft part keeps rotating, so that the engagement of the hooks of the shaft part and the hooks of the body are released by relatively rotating the shaft part and the body in the other direction. Therefore, the shaft part and the body are separated and the spinning top toy is disassembled.

In such spinning top toy, a resistance member is provided on each the body and the shaft part which are meshed with or contacted to each other, and the speed of the relative rotation in the direction of separating the body and the shaft part becomes slow. With this structure, it takes longer time to disassemble the shaft part and the body, so that the players can enjoy battle games longer.

FIG. 2 is an exploded perspective view showing the spinning top toy according to the present embodiment. FIG. 3 is an exploded cross-sectional perspective view of the spinning top toy according the present embodiment. In the present specification, the terms “top”, “bottom”, “left”, “right”, “front”, and “back” refer to the corresponding directions in FIGS. 2 and 3.

The spinning top toy 1 of the present embodiment is the spinning top toy which is capable of being used for, so called, battle games. Specifically, the spinning top toys 1 can be used for battle games in which the spinning top toys 1 collides with each other and the spinning top toy 1 of the opponent is disassembled by the impact force as shown in the right side of FIG. 1, so that one of players wins.

As shown in FIGS. 2 and 3, the spinning top toy 1 is provided with a shaft part 10, which constitutes a lower part structure and becomes a driver, and a performance variable ring 30 and a body 40, which become a layer constituting an upper part structure.

<Detail Structure>

1. Regarding the Shaft Part 10

As shown in FIG. 2, the shaft part 10 is provided with a rotating shaft 11 at the lower part, a flange 12 at the middle region in the vertical direction, and a cylindrical part 13 at the upper part.

Among the parts, the flange 12 and the cylindrical part 13 are integrally formed, so as to constitute the upper part of the shaft part, and the flange 12 and the cylindrical part 13 are fastened to the lower part of the shaft part by screws 11c (see FIG. 4).

As shown in FIG. 4, the lower part of the shaft part is provided with a bowl-shaped base part 100, and an inner fitting part 110 which is fitted into a recessed part 101 of the base part 100. In the base part 100, a circular hole 102 in which a spherical-shaped rotating shaft 11 is held is formed, and in the outside of the circular hole in the radial direction, a guide groove 103 is formed in each of two sections which are faced each other in the right-and-left direction across an axis of the rotating shaft 11. The two guide grooves 103 are positioned on the same horizontal surface. In each guide groove 103, one spherical weight member 25 is stored. The rotating shaft 11 may have a bar-shape. Each of the two guide grooves 103 may be formed with a slope which is slightly inclined downward in a direction from a first point to a second point. Further, each of the two guide grooves 103 may be formed with a slop which is slightly inclined upward in a direction from the first point to the second point. However, it is required that the guide grooves are inclined in a range which does not interfere with the performance and the effect of the present invention.

FIGS. 7(A) and 7(B) are schematic plane views showing the spinning top toy 1. As shown in the drawing, each guide groove 103 is formed in an arcuate shape so as to be concave to the axial side of the rotating shaft 11 from a top view. When each guide groove 103 is viewed in a circumferential direction of the spinning top toy 1, a center distance of the central part (midway part) of the guide groove 103 is the largest (the first point), and the center distance from the central part to both ends of the guide groove 103 is set so as to gradually become smaller (two of the second points). Here, when each guide groove 103 is viewed from the top, the guide groove 103 is formed in an arcuate shape so as to cope with the spinning top toy 1 for a clockwise direction rotation and the spinning top toy 1 for a counterclockwise direction rotation. That is, here, the rotation direction of the spinning top toy 1 can be changed by changing the body 40, but the same shaft part 10 can be used, so that each guide groove 103 is formed in an arcuate shape in a top view. Therefore, when the shaft part 10 is only used for any one of the spinning top toy 1 for the clockwise direction rotation or the spinning top toy 1 for the counterclockwise direction rotation, an arcuate guide groove 103 having one first point and one second point may be provided.

Further, the inner fitting part 110 is fitted to the recessed part 101 of the base part 100. In the fitting state, the inner fitting part 110 covers the guide grooves 103 and forms a ceiling of the guide grooves 103. With such structure, the guide path of the weight member 25 is formed. In the inner fitting part 110, as shown in FIG. 3, a cylindrical part 111 which projects upward, and a cylindrical part 112 which projects downward are formed. The cylindrical part 111 is fitted into a cavity of a columnar body 16 which will be described later. Further, the cylindrical part 112 is fitted into the hole 102 and presses the rotating shaft 11 downward.

In the flange 12 and the cylindrical part 13, a hole 14 is formed in each of two sections which are faced each other in the front-and-back direction across the axis of the rotating shaft 11.

Further, in the cylindrical part 13, a projection part 15 is formed in each of two sections which are faced each other in the right-and-left direction across the axis of the rotating shaft 11. The outer surface of the projection part 15 shares a plane with the outer peripheral surface of the flange 12.

Further, as shown in FIG. 3, a columnar body 16 is provided inside the cylindrical part 13. The columnar body 16 has a cavity in the inner part and the lower side has an opening. Further, as shown in FIG. 4, a projecting piece 16a is provided in each of the right and left sides of the lower end part of the columnar body 16, and a screw inserting hole 16b is formed therein. A cylindrical part 111 of the inner fitting part 110 is fitted into the cavity part of the columnar body 16 from the lower side. The projecting piece 16a of the columnar body 16 is fitted into the recessed part 113 of the inner fitting part 110. The columnar body 16 and the shaft lower part are mounted to the upper part of the shaft part by the screws 11c which screw through the screw inserting holes 104 of the base part 100 and the screw inserting holes 16b of the projecting piece 16a.

The position of the upper end of the columnar body 16 is not particularly limited, but it is set in a position which is higher than the upper end of the cylindrical part 13. In the top end part of the columnar body 16, a hook (engagement part) 17 stretching out in the outward radial direction at each of two sections, which are faced each other in the front-and-back direction across the axis of the rotating shaft 11, is formed.

Further, the shaft part 10 is provided with a cylindrical shape urging member 18. The urging member 18 is placed to surround the outer peripheral of the columnar body 16 inside the cylindrical part 13.

Further, the urging member 18 is provided with leg parts 18c which are formed in the outer peripheral lower end part of the cylindrical part 18a. The leg part 18c is formed at each of two sections which are faced each other in the front-and-back direction across the axis of the rotating shaft 11. The urging member 18 is energized in the upward direction by a spring 20. At the upper end of the holes 14, the upward movement of the leg parts 18c of the urging member 18 is restricted, and in the normal condition, the top end of the urging member 18 is positioned at the same height as the top end of the cylindrical part 13.

Further, at the upper surface of the ceiling part of the urging member 18, a protruding strip (projection) 21, which extends in radial direction, is formed at each of two sections which are faced each other in the right-and-left direction across the axis of the rotating shaft 11.

2. Regarding a Performance Variable Ring 30

In this embodiment, a flywheel is used as a performance variable ring 30. The performance variable ring 30 has a plate-like shape. As shown in FIG. 3, at the bottom surface of the performance variable ring 30, an annular step part 31, which is capable of storing the flange 12 of the shaft part 10 from the lower side, is formed. Further, as shown in FIGS. 2 and 3, in the upper surface of the performance variable ring 30, a projection part 32, which stretches out in the upper direction, is formed at each of two sections which are faced each other in the right-and-left direction across the axis of the rotating shaft 11. In the lower side part of each projection part 32, a recessed part 33, which is capable of storing the projection part 15 of the shaft part 10 from the lower side, is formed. Further, in the upper surface of the performance variable ring 30, a tongue-piece part 34, which extends upward, is formed directly outside each projection part 32. The tongue-piece part 34 is projected more upward than the projection part 32. As the performance variable ring 30, which can substitute the flywheel or can be integrated with the flywheel, there may be one having a projection part on the outer peripheral surface, so as to easily attack the spinning top toy 1 of the opponent, or there may be one having a recessed part on the outer peripheral surface, so as to defend from the attack from the spinning top toy 1 of the opponent.

3. Regarding a Body 40

The body 40 has a disk shape. As shown in FIG. 2, the body 40 is provided with a base 400 and a transparent cover body 401 which has a substantially identical shape with the base 400 viewed from top and which is covered on the base 400.

In the outer peripheral of the body 40, protrusions and recesses 40a are formed. Further, at the center of the base 400, a circular hole 41 is formed. The aforementioned transparent cover body 401 covers the part except the circular hole 41 and arcuate slits 46 which will be described later. Further, in the lower surface of the body 40, an annular-shaped recess part 42 which is capable of storing the projection part 32 of the performance variable ring 30 from the lower side is formed.

At the lower end of the inner circumferential surface of the inner circumferential wall 43a which partitions and forms the annular-shaped recess part 42, a hook (engagement part) 44 which overhangs in the inward radial direction is projected at each of two sections which are faced each other in the front-and-back direction across the axis of the rotating shaft 11.

Further, at the middle region in the vertical direction of the inner circumferential surface of the inner circumferential wall 43a, a protrusion 47 which overhangs in the inward radial direction is projected at each of two sections which are faced each other in the right-and-left direction across the axis of the rotating shaft 11.

In addition, at the lower end surface of the inner circumferential wall 43a, a raised part 45 in which protrusions and recesses are continuously formed so as to mesh with the protruding strips 21 is formed at each of two sections which are faced each other in the right-and-left direction across the axis of the rotating shaft 11.

Further, at the ceiling wall 43b which partitions and forms the annular-shaped recess part 42 of the body 40, an arcuate slit 46, which is capable of inserting the tongue-piece part 34 of the performance variable ring 30 from the lower side, is formed. The the arcuate slit 46 has length in which the tongue-piece part 34 can be sufficiently moved.

4. Regarding Identification Part 60

In the circular hole 41 of the body 40, an identification part 60 is mounted. The identification part 60 is used for identifying the spinning top toy 1 or the identification of a player.

As the identification, in the present embodiment, a plurality of identification parts in which decorations and/or colors, etc. are different are offered, and one of the identification parts 60 which is selected by the player is mounted in the circular hole 41 by using the projections 47 in a screw manner.

<<Assembly Method>>

Next, an example of an assembly method of the spinning top toy 1 will be described. Here, it is assumed that the assembly of the shaft part 10 has been already finished. Further, it is assumed that the assembly of the identification part 60 to the circular hole 41 has been also finished.

First, the shaft part 10 and the performance variable ring 30 are assembled in a fitting state in a manner in which the projection parts 15 of the shaft part 10 are engaged to the recessed parts 33 of the performance variable ring 30 from the lower side. Next, the assembled body is brought close to the body 40 from the lower side. At this point, the tongue-piece parts 34 of the performance variable ring 30 of the aforementioned assembled body are engaged with a predetermined end of the arcuate slits 46 of the body 40 (FIG. 5(A)). In this state, the hooks 17 of the shaft part 10 are not overlapped with the hooks 44 of the body 40 in the vertical direction. This state is the state capable of being disassembled. After that, the shaft part 10 of the aforementioned assembled body is pressed to the body 40 side. Then, the performance variable ring 30 is pressed against the lower surface of the body 40. Further, the spring 20 is contracted, so that the hooks 17 of the shaft part 10 are relatively pushed more upward than the hooks 44 of the body 40. The shaft part 10 is integrally rotated with the performance variable ring 30 with respect to the body 40 until the tongue-piece part 34 moves to the end which is the opposite side of the predetermined end (FIG. 5(B)). In this case of the rotation, it is the relative rotation between the body 40 and the performance variable ring 30 and the shaft part 10, and FIG. 5(B) shows the state in which the body 40 is rotated with respect to the shaft part 10 and the performance variable ring 30. And then, it becomes the state in which the hooks 17 of the shaft part 10 and the hooks 44 of the body part 40 are vertically overlapped. When a hand is released from the shaft part 10, the lower surface of the hooks 17 of the shaft part 10 and the upper surface of the hooks 44 of the body 40 abut by the urging force of the spring 20.

This state in which the lower surface of the hooks 17 of the shaft part 10 and the upper surface of the hooks 44 of the body 40 are abutted is the assembled state. With such structure, the shaft part 10, the performance variable ring 30, and the body 40 are assembled, so that the spinning top toy 1 is assembled.

<<How to Play>>

Next, an example of how to play with the spinning top toy 1 will be described.

In the example of how to play, by spinning the spinning top toy 1, a battle is performed with the opponent.

In this case, a charge of the spinning force of the spinning top toy 1 is performed by the launcher 50 as shown in FIG. 6. In the inside part, the launcher 50 is provided with a disk which is not shown, and the disk is energized in one rotational direction by the power spring which is not shown. When the string, which is not shown, wound around the disk is pulled by a handle 51, the disk is rotated, and therefore, the spinning top holder 53 is rotated. The rotation of the spinning holder 53 is transmitted to the spinning top 1 by the forks 54 projected downward, so that the spinning top toy 1 is rotated. In this case, the forks 54 are inserted to the arcuate slits 46 of the body part 40. When the handle 51 of the launcher 50 is pulled to the end, the rotation of the disk and further, the spinning top holder 53 is stopped, and on the other hand, the spinning top toy 1 is rotated further by the inertia force, so that the spinning top toy 1 is released from the spinning top holder 53 in accordance with the tilting faces 54a of the forks 54. The reference numeral 52 denotes a rod which is capable of protruding and retracting with respect to the spinning top holder 53. When the spinning top toy 1 is mounted to the spinning top holder 53, the rod 52 is pressed by the upper surface of the spinning top toy 1 so as to be retracted to the spinning top holder 53. For example, the rod 52 is used to detect whether the spinning top toy 1 is mounted or detached.

The spinning top toy 1 which is launched in such manner, is rotated in a predetermined field. When it collides with the spinning top toy 1 of the opponent, by the impact fore or the frictional force, etc. of the collision, the opposite direction force, which is opposite to the rotation direction of the shaft part 10 and the performance variable ring 30, is applied to the body 40. With this, the body part 40 is relatively rotated to the direction opposite to the rotation direction of the shaft part 10 and the performance variable ring 30.

And then, the protruding strips 21 are engaged with the raised parts 45 of the body 40. In this case, since the urging force of the spring 20 is applied to the protruding strips 21, every time the impact force is applied by the collision, the shaft part 10 is relatively rotated with respect to the body 40 and the engagement position is changed. When it reaches at the locking releasing position, the hooks 44 of the body 40 are removed from the hooks 17 of the shaft part 10, so that the body 40 is separated from the shaft part 10 by the urging force of the spring 20. As shown in the right side of FIG. 1, the spinning top toy 1 is disassembled.

<Effect of Guide Grooves 103 and Weight Members 25>

The weight members 25 are moved from the second point side to the first point of the guide grooves 103 by the centrifugal force or the inertia force and it keeps the position (FIG. 7(A)). When the spinning top toy 1 collides with the spinning top toy of the opponent (not shown), with this collision, the weight members 25 are moved from the first point side to one of the second points of the guide grooves 103 in response to the rotation direction of the spinning top toy 1 by the inertia force (FIG. 7(B)). That is, the weight members 25 are moved to the second points where the center distance to the axis of the rotating shaft is smaller in the guide groove 103. When the weight members 25 are moved to the second points, the rotation energy or the rotation power of the shaft part 10 becomes small. As a result, the speed of the relative rotation in the direction of separating the body 40 and the shaft part 10 becomes slow, so that it takes longer time to disassemble the spinning top toy. Therefore, in the present embodiment, as the rotation resistance, the protruding strips 21 are formed in the shaft part 10 and the raised part 45 of the body 40 is formed in the body 40, but if desired, the rotation resistance can be omitted.

<<Modification Example of the Present Invention>>

The embodiments of the present invention were described above, but the present invention is not limited to the aforementioned embodiments, and needless to say, various modifications may be made within the scope that does not depart from the essential point of the present invention.

For example, the aforementioned embodiment, as the rotation resistance between the shaft part 10 and the body 40, the protruding strips 21 are formed in the shaft part 10 and the raised part 45 of the body 40 is formed in the body 40, but as other shapes, a convex part and a concave part may be formed. The number is also not limited to the aforementioned embodiment. Further, the rotation resistance may be a rubber, etc. formed in the opposing face between the shaft part 10 and the body 40. In this case, by the impact force, etc. from the external part, the shaft part 10 and the body 40 are relatively and gradually rotated in the disassembling direction.

Further, in the aforementioned embodiment, the half of the guide groove 103 is formed in an arc shape, and as a whole, it is formed in an arcuate shape, but the half of the guide groove 103 may be formed in a linear shape, and as a whole, it may be formed in a V-shape. Needless to say, when the spinning top toy, which specifies the rotation direction, is used, only half of the V-shaped guide groove 103 may be formed.

The language present invention or invention should not be improperly interpreted as an identification of criticality, should not be improperly interpreted as applying across all aspects or embodiments (i.e., it should be understood that the present invention has a number of aspects and embodiments), and should not be improperly interpreted as limiting the scope of the application or claims. In this disclosure and during the prosecution of this application, the terminology “embodiment” can be used to describe any aspect, feature, process or step, any combination thereof, and/or any portion thereof, etc. In some examples, various embodiments may include overlapping features.

[Effect]

According to the aforementioned spinning top toy, when the spinning top toy collides with the spinning top toy of the opponent, the weight member is moved from the first point to the second point of the guide groove by an inertia force. Since the distance to the center of the rotating shaft of the spinning top toy from the second point is smaller than the distance from the first point in the guide groove, when the weight member is moved to the second point side, the rotation energy or the rotation power of the shaft part becomes small. As a result, the speed of the relative rotation in the direction of separating the body and the shaft part becomes slow, so that it takes longer time to disassemble the spinning top toy.

According to the aforementioned spinning top toy, since the guide groove is formed in an arc shape in a top view so as to gradually reduce the distance with the center from the first point to the second point, the weight member is smoothly moved inside the guide groove when receiving the external force.

According to the aforementioned spinning top toy, since the shaft part is capable of being applied for both rotation directions, this type of the spinning top toy can rotate in both directions. Further, since a rotation direction of the spinning top toy can be reversed by replacing the body, the spinning top toy having high usability can be realized.

According to the aforementioned spinning top toy, since the guide groove is formed in each of two sections which are faced each other across the center of the rotating shaft, the spinning top toy having a stable rotation balance can be realized.
