Abstract
The present invention provides a crystal ball which move upwardly and downwardly, wherein the convex surface of the planetary gears which is used to drive the revolving disk is a bevel to form a bulgy state, and a mantle surrounding said bulgy convex surface is on the upper side of the revolving disk; and the dynamic phenomena including revolution, rotation and moving upwardly and downwardly performed by the doll inserted into said mantle are driven by the rotation of the revolving disk and the planetary gears.
Claims5
A drive for vertically reciprocating an object mounted on a longitudinal stick, the drive comprising
- a planetary gearing including a planetary gear having an upper side and an upright member extending upwardly from said planetary gear upper side and having a bevelled upper surface;
- a revolving disk containing a bore through which said upright member extends;
- and
- a mantle mounted on said revolving disk and having an upper surface,
- said mantle defining a space therebelow in which said upright member on said planetary gear is located;
- and
- a bulgy cylinder mounted to said upper surface of said mantle corresponding to said upright member on said planetary gears, said bulgy cylinder having an opening through which the longitudinal stick mounting the object is inserted so that the end of the longitudinal stick is in contact with said beveled upper surface of said upright member of said planetary gear.
In a crystal ball containing a plurality of objects such as figures mounted on corresponding ones of a plurality of longitudinal sticks, the crystal ball also including a base, a resilient plug mounted on said base, a transparent cover sealingly mounted on said resilient plug and a fixed base mounted on said resilient plug and including a ring gear, the improvement comprising a drive for vertically reciprocating the objects and the longitudinal sticks, the drive comprising:
- a planetary gearing mounted on said fixed base and including three planetary gears meshing with said ring gear and meshing with a central drive gear, each of said planetary gears having an upper side and an upright member extending upwardly from said planetary gear upper side and having a bevelled upper surface;
- means for rotating said central drive gear;
- a revolving disk containing a plurality of bores spaced apart on a peripheral portion thereof, each bore corresponding to an upright member which extends through said bore;
- and
- a mantle having an annular base mounted on a peripheral portion of said revolving disk, said mantle having an upper surface,
- said mantle defining a space therebelow in which said upright members on said planetary gears are located;
- and
- three bulgy cylinders mounted to said upper surface of said mantle corresponding to said upright members on said planetary gears, said bulgy cylinders having an opening through which the longitudinal sticks mounting the objects is inserted so that the ends of the longitudinal sticks are in contact with the corresponding ones of said beveled upper surfaces of said upright members of said planetary gears.
