The present application claims priority under 35 U.S.C. 119 to Japanese Patent Application No. 2018-203869 filed on Oct. 30, 2018. The entire content of Japanese Patent Application No. 2018-203869 is incorporated herein by reference.
The present invention relates to a spinning top launching device.
Conventionally, it is well known that a spinning top launching device has a structure in which a spinning top toy holder is provided in the upper side and the lower side of a device housing. In the spinning top launching device, a spinning top toy is mounted in any one of the spinning top toy holders. When a rotation driving mechanism is operated by an operation unit, the spinning top toy is rotationally energized and launched. In the spinning top launching device, the rotation direction of the spinning top toy which is launched can be changed depending on which spinning top toy holder the spinning top toy is mounted.
By the way, in this spinning top launching device, the spinning top toy which was launched had to be mounted to any one of the spinning top toy holders. However, when the operation unit was operated, the spinning top toy holder in which the spinning top toy was mounted was not only rotated, but also rotated the spinning top toy holder in which the spinning top toy was not mounted at the same time. Therefore, there was a case in which the spinning top toy holder in which the spinning top toy was not mounted collided with an external obstacle so as to be destroyed.
As such the spinning top launching device, normally, the operation unit was locked, and, for example, it may be considered that only when a cap was mounted to the other one of spinning top toy holders, it was unlocked (see e.g., Patent Document 1).
[Patent Document 1] Japanese Registered Utility Model Publication No. 3160157
However, there were the following problems in the spinning top launching device described in Patent Document 1.
That is, the spinning top toy was launched downwardly, so that after the spinning top toy was mounted in the spinning top toy holder, normally, the spinning top toy was directed toward the lower side, and the operation unit was operated.
However, in the spinning top launching device described Patent Document 1, after the spinning top toy was mounted to the other one of the spinning top toy holders, even when the spinning top toy was directed toward the upper side, when the operation unit was operated, the spinning top toy was launched. In this case, the spinning top toy was dropped off from the device housing, so that the spinning top toy itself may be destroyed.
An object of the present invention is to provide a spinning top toy which can prevent an erroneous shooting.
In view of the above problem, a spinning top launching device for spinning a spinning top on a floor includes a rotation driving mechanism, first and second holders, a cap, a first locking mechanism, and a second locking mechanism.
The rotation driving mechanism includes an operation unit and a rotation shaft. The operation unit includes an operation component. The first and second holders are configured on first and second ends of a rotation shaft respectively. The top toy is arranged to be attached to one of the first and second holders. The cap is to cover one of the first and second holders. The first locking mechanism is configured to block rotating the first and second holders by locking the operation component or by locking the first and second holders when the cap is not mounted on one of the first and second holders, and is configured to unlock rotating the first and second holders by being engaged with the cap when the cap is mounted on one of the first and second holders and when the cap is arranged to face upwardly towards a upper side. The second locking mechanism is configured to block rotating the first and second holders by locking the operation component or by locking the first and second holders when the cap is mounted on one of the first and second holders and when the cap is arranged to face downwardly to a lower side opposite to the upper side.
Hereinafter, a spinning top toy of the present invention will be described based on embodiments shown in the drawings.
As shown in
As shown in
A rotation direction of the launched spinning top toy 50 can be changed depending on which one of the spinning top toy holders 2, 3, the spinning top toy 50 is mounted. Further, in the spinning top toy holder in which the spinning top toy 50 is mounted, a cap 8 covers.
The operation lever 7 triggers the operation of the rotation driving mechanism 10 and it is configured to be operated by a finger.
The operation lever 7 is installed in the device housing 1 through a shaft 7b, and is rotatable in a plane orthogonal to the rotation shaft 6. By a spring 25 (see
The rotation driving mechanism 10 applies rotational force to the spinning top toy holders 2, 4 which are installed to the both ends of the rotation shaft 6, and the rotation shaft 6 or the aforementioned operation lever 7 also configures the operation components of the rotation driving mechanism 10.
The rotation driving mechanism 10 is provided with a coil spring 11 which is the power source. The coil spring 11 is stored in a cylindrical spring storage part la which is formed inside the device housing 1. The coil spring 11 is engaged with one end of the rotation shaft 6, and the other end is engaged with the spring storage part la. Therefore, when the rotation shaft 6 is rotated in one direction, the coil spring 11 is wound up. Further, when the rotation shaft 6 is rotated in the other direction, the wound coil spring 11 is released.
Further, the rotation driving mechanism 10 is provided with a ratchet mechanism 13. The ratchet mechanism 13 is used to gradually wind up the coil spring 11.
In the rotation shaft 6, a disk 12 is fixedly provided. On the upper surface of the disk 12, a ratchet teeth 13a which configures one side of the ratchet mechanism 13 is formed. On the other hand, in the device housing 1, the lever 14 is installed by a shaft 14a. In one end of the lever 14, a ratchet hook 13b which is configured in the other side of the ratchet mechanism is formed. As shown in
Further, the other end 14b of the lever 14 is provided opposite to the operation lever 7, and when the operation lever 7 operates, the lever 14 is operated by the operation lever 7, so that the meshing between the ratchet hook 13b and the ratchet teeth 13a is released.
The cap 8 is mounted to one of the spinning top toy holders 2, 3, and it is used to release a lock of the operation lever 7 by the first locking mechanism 20 or the second locking mechanism 30 which will be described later.
The cap 8 is provided with two hooks 8a projecting downwardly on the lower end circumferential surface. The hooks 8a are provided at a position symmetric with respect to the central axis of the cap 8.
The cap 8 is provided with a flexible belt 8b. At the top end of the flexible belt 8b, a ball-shaped engagement part 8c is formed. The cap 8 is held by inserting the ball-shaped engagement part 8c into an arcuate hole 1b formed at the side wall of the device housing 1. The cap 8 can be reversed upside down, and can be rotated in a predetermined direction around the rotation shaft 6. With this, the cap 8 can be selectively mounted to the spinning top toy holders 2, 3 positioned in the upper side and the lower side. Further, the hooks 8a are inserted and fitted into the rectangular holes 1c formed in the device housing 1, and by rotating the cap 8 in a predetermined direction around the rotation shaft 6, it can be engaged with the device housing 1. With such configuration, in the device housing 1, the arcuate slit 1d connecting to the rectangular holes 1c is formed.
The first locking mechanism 20 locks the operation lever 7 when the cap 8 is not mounted to any one of the spinning top toy holders 2, 3, and when the cap 8 is mounted to any one of the spinning top toy holders 2, 3, the first locking mechanism 20 is engaged with the cap 8 and unlocks the operation lever 7.
As shown in
The second locking mechanism 30 is engaged with the cap 8 and locks the operation lever 7 when the cap 8 mounted to any one of the spinning top toy holders 2, 3 is positioned in the lower side, and the second locking mechanism 30 releases the lock when the cap 8 is positioned in the upper side.
As shown in
In the seesaw body 31, a rotation moment around the shaft of the arm 31a with respect to the shaft 32 is set larger than the arm 31b. In the seesaw body 31, when the spinning top toy holders 2, 3 are positioned in the upper side and the lower side in the state in which the cap 8 is not mounted to the spinning top toy holders 2, 3, by the gravity, the top end of the arm 31a is rotated to move downwardly, and the top end of the arm 31b is rotated to move upwardly. In this state, the top end part of the arm 31b moves away from the moving area of the projection 7c of the operation lever 7 and the lock is released (see
According to the spinning top launching device of the present embodiment, when rotating any one of the spinning top toy holders 2, 3, the coil spring 11 is wound up.
Further, when the spinning top toy 50 is mounted to one of the spinning top toy holders 2, 3, the cap 8 is mounted to the other one. With this, the lever 21 is rotated against the urging force of the spring 22 by the hook 8a of the cap 8, and the free end part 21b of the lever 21 is moved away from the top end part 7a of the operation lever 7, so that the lock of the first locking mechanism 20 is released.
Further, when the spinning top toy holder 2 or 3 in which the spinning top toy 50 is mounted is positioned in the lower side, the seesaw body 31 is rotated by the gravity, and accordingly, the arm 31a is moved downwardly and the other end part 1b is moved away from the rotation area of the operation lever 7, so that the lock is released. With this, the lock of the second locking mechanism 30 is released.
Therefore, by operating the operation lever 7, the spinning top toy can be launched.
In the state in which the spinning top toy 50 is positioned in the upper side, the rotation of the seesaw body 31 is blocked by the hook 8a of the cap 80, so that the lock of the second locking means 30 is not released.
Therefore, the operation of the operation lever 7 cannot be performed, and the spinning top toy 50 is not erroneously launched.
Only when the cap is mounted to any one of the spinning top toy holders, the operation unit can be operated. Further, even when the cap is mounted to any one of the spinning top toy holders, and when the cap is mounted in the lower side, the operation unit cannot be operated. This means that the spinning top toy can be launched only when the spinning top toy is mounted in the lower side. As a result, an erroneous shooting of the spinning top toy can be prevented.
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, in the aforementioned embodiment, the coil spring 11 is used as the power source of the rotation driving mechanism 10, but it may be applied in a case of using a motor. Further, it may be applied in which normally, the spinning top toy holder is rotated through the rotation shaft by pulling a string (operation unit) which is wound up to the rotation body by the coil spring. In addition, it may be applied in which the spinning top toy holder is rotated by operating the rotation driving mechanism, which includes a pinion and a rotation shaft, by a rack belt (operation unit). Further, the locking component may be a component which linearly moves.
