Abstract
A crystal ball has an assembled motive die set. The crystal ball includes a music box and a driving base, wherein the driving base has a plurality of driven gears which are driven by a center motive gear installed on the base of the driving base. Assembled motive die sets representing different motion types are mounted on the upper cover of the base with respect to the driven gears, and are changeable as desired. The motive die set is influenced by the dynamic force of the music box through the driving base.
Claims10
A crystal ball with an assembled motive die set, comprising:
- a music box;
- a driving substrate, a portion of which is rotatably connected with the music box by a longitudinal output axle, the driving substrate comprising:
- a disk shaped base portion, having an annular raised portion on an outer periphery thereof,
- a motive gear, mounted in a center of the disk shaped base portion, operably connected to the longitudinal output axle so as to rotate the motive gear,
- at least one driven gear, provided on the disk shaped base portion, each driven gear driven to rotate by force provided from the motive gear, and
- an upper cover, fixed to the annular raised portion of the disk shaped base portion, said upper cover including at least one driven gear opening corresponding to a position of one of the driven gears;
- and
- at least one assembled motive die set, provided on the upper cover of the driving substrate, and driven by one of the driven gears of the driving substrate, wherein one of the motive die sets comprises:
- a die set body, having an upper disk face, a lower neck portion, and an opening defined therethrough,
- a rotary disk, and
- a claw member,
- wherein the lower neck portion of the die set body is positioned within one of the driven gear openings of the upper cover of the driving substrate, and wherein the rotary disk is fixed to the claw member through the opening of the die set body so that the rotary disk is disposed above the upper disk face of the die set body and rotates concurrently with the claw member with respect to the die set body, the claw member being, in turn, rotatably engaged with one of the driven gears.

A driving substrate of a crystal ball, comprising:
- a base portion, having a center axle opening and at least one axle hole defined therein;
- a cover portion, mounted so as to freely rotate, having at least one radial elongated hole therethrough;
- a motive gear, having a disk shaped portion and a center axle portion, the motive gear being rotatably engaged with a rotating means, the center axle portion being positioned in the center axle opening of the base portion;
- and
- at least one driven gear, rotatably engaged with the motive gear, the driven gear having a disk shaped portion and an axle projection on a lower face thereof, the axle projection being positioned in the axle hole of the base portion,
- wherein the at least one driven gear is provided with a longitudinal column provided in an offset position on an upper face of said driven gear, and
- wherein the longitudinal column projects through the radial elongated hole of the cover portion, so that as the driven gear is rotated, the cover portion is driven to rotate in a first direction, and then in a second direction, in alternating fashion.

A motive die set assembly, comprising:
- a cylindrical die set body having a neck portion and an upper portion, said upper portion being above said neck portion and at least a part of said upper portion extending outwardly beyond said neck portion, said body having an opening defined therethrough;
- a rotary disk member disposed within said upper portion of the cylindrical die set body, said rotary disk member having a pin member extending therefrom which is disposed at a location offset from a center of said rotary member;
- a claw member, said rotary member being coupled with said claw member through said opening in said body such that said rotary member is rotated relative to said body when said claw member is rotated relative to said body;
- and
- a vibrating block, defining a pin engagement opening, the pin member extending from said rotary member being received in said pin engagement opening,
- wherein said upper portion of said body includes a pair of supporting walls extending therefrom, said vibrating block being supported by said supporting walls.
