SPINNING TOP LAUNCHING DEVICE

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority under 35 U.S.C. 119 to Japanese Patent Application No. 2017-016632, filed on Feb. 1, 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 launching device.

Description of the Related Art

Conventionally, it was well-known that a toy was provided with a spinning device (spinning top launching toy) including a spinning top for clockwise-direction rotation, a spinning top for counterclockwise-direction rotation, and a spinning mechanism which rotated the spinning top in a clockwise direction or a counterclockwise direction as described in Japanese Registered Utility Model Application Publication No. 3098449.

According to the aforementioned spinning top launching toy, a user selected either one of the spinning top for clockwise-direction rotation and the spinning top for counterclockwise-direction rotation, and depending on the spinning top, the rotational direction of the spinning top could be freely selected, so that when the user played a spinning tops combat game, it enhanced strategical characteristics.

According to the spinning top launching toy described in Japanese Registered Utility Model Application Publication No. 3098449, a rack belt was used as an operation member, and an opening part for clockwise-direction rotation and an opening part for counterclockwise-direction rotation were formed in a casing. An opening part to which the rack belt was introduced was changed depending on whether in the clockwise direction or the counterclockwise direction the spinning top was to be rotated.

However, according to such spinning top launching device, every time the rack belt was introduced, the user had to confirm the opening part to which the rack belt was introduced and the direction of the rack belt. That was troublesome.

On the other hand, instead of the rack belt, in a case in which a holder was rotated by pulling a string, which was wound around a driving wheel, and rotating the driving wheel on which a coil spring was mounted, such configuration could not be employed because the winding direction of the string, which was wound around the driving wheel, was fixed, and when the string was pulled, the driving wheel and also the holder were rotated in only one direction.

[Outline]

FIG. 1 is a perspective view, which is viewed from an upper surface side, showing a spinning top launching device; FIG. 2 is a perspective view, which is viewed from a lower surface side, showing a spinning top launching toy; and FIG. 3 is a perspective view, which is viewed from an upper surface side, showing a spinning top.

First, the outline of the spinning top launching device 100 in an embodiment will be described.

In the spinning top launching device 100, in a case in which a spinning top 50 is to be rotated in a clockwise direction when viewed from the top, after the spinning top 50 is held by a holder 11 in a state in which the switching lever (e.g., rotation direction switching member) 14 is moved to a back side of a casing 10, a driving lever 12 is pulled hard onto the front side in a state in which the spinning top 50 is directed to a field. Then, the spinning power is applied to the spinning top 50 in the clockwise direction by the rotation of the holder 11, and the spinning top 50 is launched toward the field at the point in which the driving lever 12 is pulled to the end.

On the other hand, in the spinning top launching device 100, in a case in which the spinning top 50 is rotated in the counterclockwise direction when viewed from the top, after the spinning top 50 is held by a holder 11 in a state in which the switching lever 14 is moved to the front side of the casing 10, the driving lever 12 is pulled hard onto the front side in a state in which the spinning top 50 is directed to the field. Then, the spinning power is applied to the spinning top 50 in the counterclockwise direction, and the spinning top 50 is launched toward the field at the point in which the driving lever 12 is pulled to the end.

Further, the operating the switching lever 14 and holding the spinning top 50 may be in reverse order.

Hereinafter, the detail of the spinning top launching device 100 in the embodiment will be described.

[Detailed Structure]

1. External Appearance

The shape of the casing 10 is not particularly limited to a rectangular shape, but the casing may be formed in a size which is possible to hold by one hand.

On the lower surface of the casing 10, the holder 11 which is capable of holding and releasing the spinning top 50 is provided. The holder 11 is provided with a circular plate 11a which has a circular shape when viewed from the lower surface. The circular plate 11a is fixed to a shaft 11b which is positioned in the center of the circular plate. In the outer peripheral part of the lower surface of the circular plate 11a, the fork pieces 11c, which are extending vertically and downwardly, are positioned facing each other across the shaft 11b. Each fork piece 11c is formed in an arcuate shape when viewed from the lower surface, and the edges 110c, 110c in both sides of the circumferential direction of the circular plate 11a are inclined with respect to the lower surface of the circular plate 11a so that each fork piece 11c is formed in a trapezoidal shape. Further, a locking projection 111c is formed in the inner surface of each fork piece 11c.

When the spinning top 50 is held in the holder 11, each fork piece 11c is inserted to each slit 51 of the upper surface of the body part of the spinning top 50 as shown in FIG. 3. In this case, the width of one end side, which corresponds to the rotation direction of the spinning top 50, of each slit 51 of the spinning top 50 is wider than the other end side as shown in FIG. 3, so that each fork piece 11c is inserted to the wide side of each slit 51. After that, when the spinning top 50 is rotated with respect to the holder 11 in a direction of moving each fork piece 11c to the narrow side of each slit 51, the locking projection 111c slides under the edge of the narrow side of each slit 51. Accordingly, the spinning top 50 is held in the holder 11. In this state, when the holder 11 is rotated in a direction opposing to the rotation direction of the aforementioned spinning top 50, the spinning power is applied to the spinning top 50. After that, when the rotation of the holder 11 stops, the spinning top 50 only spins with inertia force. Each fork piece 11c moves from the narrow side of each slit 51 to the wide side, and one edge 110c of each fork piece 11c slides and contacts with the tip edge of the wide side of each slit 51, so that the holding is released and the spinning top 50 is launched.

A driving lever 12 is provided in the front side surface of the casing 10. The driving lever 12 is provided with a basic shaft 12a and finger hooking parts 12b, 12b which overhang in a direction separating each other from two positions facing across the center of the basic shaft 12a. A top end of a string 22, which will be described later, is connected with the basic shaft 12a.

A switching lever 14 is provided in the right side surface of the casing 10. The switching lever 14 is used for switching the rotation direction of the holder 11. The switching lever 14 is configured to be movable in the front and back direction of the casing 10.

A lock lever 15 is provided in the lower surface of the casing 10. The lock lever 15 is used for locking the operation of the switching lever 14. The lock lever 15 is configured to be movable in the front and back direction of the casing 10.

2. Internal Mechanism
(Driving Mechanism)

A driving wheel 20 as shown in FIG. 4 is provided inside the casing 10. As shown in FIG. 6, the driving wheel 20 is a spring gear in which a coil spring 21 is mounted. One end of the coil spring 21 is fixed to a shaft 21a, and the other end of the coil spring 21 is fixed on the exterior wall of the driving wheel 20. The driving wheel 20 is freely rotatable with respect to the shaft 21a. The driving wheel 20 is mounted to the casing 10 by fixing the shaft 21a to the casing 10.

A pulley 20a is provided in the upper part of the driving wheel 20. The base end of the string 22 which is an operation member is fixed to the pulley 20a. The string 22 is wound on the pulley 20a and is passed through a hole, which is not shown, in the casing 10, and the tip end of the string 22 is connected to the basic shaft 12a of the driving lever 12. With such structure, when the driving lever 12 is pulled, the driving wheel 20 is rotated in one direction, and the coil spring 21 is wound up against the energizing force of the coil spring 21. When the driving lever 12 is released by hand, the driving wheel 20 is rotated in a direction to unwind the coil spring 21 by the energizing force of the coil spring.

(Input Gear and Output Gear)

An input gear 20b is formed in the lower part of the driving wheel 20. Further, an output gear 30 is fixedly provided on the shaft 11b of the holder 11 inside the casing 10 (FIG. 5).

(Movable Gear)

A plate-shaped operating body 24 which is rotatable around the shaft 21a as a center is provided in the lower side of the driving wheel 20 (FIG. 7). The first movable gear (planetary gear) 25 and the second movable gear (planetary gear) 26 are provided in the operating body 24. The first movable gear 25 is also denoted as a first gear. Likewise, the second movable gear 26 is also denoted as a second gear. The first movable gear 25 and the second movable gear 26 always mesh with the input gear (sun gear) 20b, and they are rotated around the input gear 20b in accordance with the movement of the operating body 24. The first movable gear 25 meshes with both the input gear 20b in the first revolution position and a gear 29 which always meshes with the output gear 30 (FIG. 6(A)). The gear 29 is also denoted as a third gear. With such structure, the holder 11 becomes rotatable in the clockwise direction in the top view. On the other hand, the second movable gear 26 meshes with both the input gear 20b and the output gear 30 in the second revolution position (FIG. 6(B)). With such structure, the holder 11 becomes rotatable in the counterclockwise direction in the top view.

(Switching Mechanism)

In the aforementioned operating body 24, an arcuate-shaped partial gear (intermittent gear) 27 is provided. On the other hand, the switching lever 14 which is the rotation direction switching member moves in the front and back direction along the rail 10a formed in the side surface of the casing 10. The switching lever 14 includes the upper frame and the lower frame, and inside the switching lever, a rack plate 31 is fixedly provided. A plurality number of tooth 31a is formed in one side surface of the rack plate 31. The tooth 31a of the rack plate 31 meshes with the tooth of the aforementioned partial gear 27. The operating body 24 is rotated and moved by moving the switching lever 14 back and forth.

Further, a slit 31b is provided in the rack plate 31, and the rack plate 31 is elastic in a width direction. A projection 31c is formed on one side surface of the rack plate 31 in the width direction. In the predetermined front and back positions of the switching lever 14, the projection 31c provides click feeling when it is engaged with a recessed part 10c of the casing 10.

(Lock Mechanism)

The lock lever 15 is formed in a plate shape. The lock lever 15 is configured to be movable in the front and back direction.

Slits 15b are provided in both sides of the lock lever 15 in the width direction, and the lock lever 15 is elastic in the width direction. Projections 15c are formed in both sides of the lock lever 15 in the width direction. In the predetermined front and back positions of the lock lever 15, the projections 15c provide click feeling when they are engaged with recessed parts 10d of the casing 10. In one end of the lock lever 15, a locking projection 15d is provided. The locking projection 15d is engaged with one of the two recessed parts 24a, 24a formed in the circumference of the operating body 24, and the operating body 24 is locked in the first revolution position and the second revolution position (FIG. 7(A) and FIG. 7(B)).

The embodiment of the present invention was described above, but the present invention is not limited to the aforementioned embodiment, 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, in the aforementioned embodiment, the string-type spinning top launching device 100 is described, but a spinning top launching toy, in which a pinion gear is rotated by using a belt-shaped rack belt being detachable and linearly forming rack tooth in a side surface, and in which the driving wheel 20 is rotated in one direction by the spinning power of the pinion gear, may be applied. In this case, the pinion gear may be provided in the same shaft with the driving wheel 20 or may be provided in a different shaft.

Further, in the aforementioned embodiment, the gear 29 always meshes with the output gear 30, but the gear 29 may be a movable gear and may always mesh with the first movable gear 25 as a gear. It may be integrally moved with the first and second movable gears 25, 26. Likewise, the first and second movable gears 2526 do not have to always mesh with the input gear 20b. It is possible that only one of the first and second movable gears 25, 26 is always meshes with the input gear. It is also possible that the second movable gear 26 and the gear 29 always mesh with the output gear 30.

In addition, in the aforementioned embodiment, the switching lever 14 and the lock lever 15 are configured to perform a linear reciprocating movement, but needless to say, the movement direction is not limited to this.

Further, in the aforementioned embodiment, the power transmission mechanism is configured as the gear mechanism, but a roller, a pulley, or a crank mechanism may be used instead of the gear.

Furthermore, in the aforementioned embodiment, the driving wheel 20 and the holder 30 are spaced apart, but the driving wheel 20 and the holder 30 may be provided in a superposed manner and the driving wheel 20 and the holder 30 may be connected by a gear, or the like.

Furthermore, in the aforementioned embodiment, the first movable gear (planetary gear) 25 and the second movable gear (planetary gear) 26 are provided in the input gear 20b side which constitute the power transmission mechanism, and the gear 29 is provided in the output gear 30 side so as to always mesh with the output gear 30 which configures the power transmission mechanism, but it may be reversed.
