ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a double deck rotational music box and particularly to a double deck rotational music box with an upper deck and a lower deck rotating in opposite direction.
2. Description of the Prior Art
Conventional rotational water ball music box (as shown in
FIG. 1
) mainly includes a base A, a musical kit B, a seal cap C and a rotationable ornament D. There is a lucid glass ball E filled with liquid inside being placed above the top of the base A. At the bottom of the glass ball E, there is an opening covered by the seal cap C which has a rotational frame F located therein. At the bottom of the rotational frame F, there are a plurality of cavities G. The seal cap C covers the glass opening to form a water tight sealing. The ornament D is fixedly mounted on a top end of the rotational frame F.
The musical kit B is a conventional spring type musical kit which includes a spring knob H, a spindle I, a barrel J, a first gear K and a plurality of screw bores L which enable screws M to fix the musical kit B on the base A. The spring knob H passes through the bottom of the base A and extends under the base bottom. At one end of the barrel J, there is a second gear N axially aligned with the barrel J and engaged with the first gear K. The spindle I has one end attached to the first gear K and another end thereof attached to a driving disk P. Above the driving disk p, there are a plurality of struts Q engageable with the cavities G.
Turning the spring knob H, the barrel J will be rotated to generate music while the second gear N will drive the first gear which in turn rotates the driving disk P, struts Q engageable with the cavities G.
However the ornament D may only make one directional rotation. It makes people bored easily. Furthermore the spring knob H is located under the bottom of the base A. A user has to take and turn the base A to access and turn the spring knob H. It is prone to incur accident or even break the glass ball E. It could easily result in harmful accidents, particularly to children.
SUMMARY OF THE INVENTION
It is therefore an object of this invention to provide a double deck rotational music box that includes a base, a musical kit, a rotational frame and a rotational upper cap. Through installation change of the musical kit and the spindle and spring knob of the musical kit, the rotational frame and the upper cap may rotate in opposite directions concurrently. It thus may create a more amusing visual effect.
It is another object of this invention to provide a double deck rotational music box which has the spring knob located at an upper portion of the base. A user may turn the spring knob easily without taking and turning the base. It thus greatly reduces the risk of breaking the glass ball or creating a harmful accident.
