Abstract

A first locking mechanism is configured to block rotating the first and second holders by locking an 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. A 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.

First claim

What is claimed is:

1. A spinning top launching device for spinning a spinning top on a floor, comprising:
a rotation driving mechanism including an operation unit and a rotation shaft, the operation unit including an operation component;
first and second holders being configured on first and second ends of the rotation shaft respectively, the top being arranged to be attached to one of the first and second holders;
a cap to cover one of the first and second holders;
a first locking mechanism being 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 being 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
a second locking mechanism being 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,
the second locking mechanism includes a seesaw body being configured to rotate on a plane parallel to the rotation shaft,
the seesaw body includes an arm having a first end and a second end opposite to the first end, and a fulcrum between the first and second end,
the seesaw body is configured to set a rotational moment around a shaft of the arm with the first end larger than the second end opposite to the first end so as to be rotated by a gravity, and is configured to perform locking and unlocking by the second end,
the arm is configured to lock the operation component at the second end or lock the first and second holders at the second end by restricting a rotation of the seesaw body, and unlock the operation component or unlock the first and second holders by releasing the rotation restriction of the seesaw body.

2. The spinning top launching device according to claim 1 , wherein
the first locking mechanism includes a lever which is configured to be rotated in a plane orthogonal to the rotation shaft, and is configured to lock and unlock the operation component or the first and second holders by the lever,
the first locking mechanism includes a spring,
the lever is urged by the spring, and
the lever is configured to be rotated against an urging force of the spring to unlock.

3. The spinning top launching device according to claim 1 , wherein
the operation unit is locked by the first locking mechanism and the second locking mechanism.

4. The spinning top launching device according to claim 3 , wherein
the operation unit includes an operation handle which is configured to be rotated in a plane orthogonal to the rotation shaft.

5. The spinning top launching device according to claim 1 , further comprising
a coil spring as a power source to rotate the top toy, wherein
the coil spring is wound up by rotating the first and second holders, and
the coil spring is released by a user operating the operation unit.

6. A spinning top launching device for spinning a spinning top on a floor, comprising:
a rotation driving mechanism including an operation unit and a rotation shaft, the operation unit including an operation component;
first and second holders being configured on first and second ends of the rotation shaft respectively, the top being arranged to be attached to one of the first and second holders;
a cap to cover one of the first and second holders;
a first locking mechanism being 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 being 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;
a coil spring as a power source to rotate the top toy, the coil spring being formed in spiral;
a second locking mechanism being 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,
the second locking mechanism including a seesaw body being configured to rotate on a plane parallel to the rotation shaft,
the seesaw body including an arm having a first end and a second end opposite to the first end, the seesaw body including a fulcrum between the first and second end,
the seesaw body being configured to set a rotational moment around a shaft of the arm with the first end larger than the second end opposite to the first end so as to be rotated by a gravity, and being configured to perform locking and unlocking by the second end,
the arm being configured to lock the operation component at the second end or lock the first and second holders at the second end by restricting a rotation of the seesaw body, and unlock the operation component or unlock the first and second holders by releasing the rotation restriction of the seesaw body
the coil spring being configured to be wound up by rotating the first and second holders,
the coil spring is released by a user operating the operation unit.
