Abstract
Abstract This invention relates to a kind of the structural improvement of the motion type solid water ball. The major improvement is to place permanent magnets respectively on the upper movable plate and the lower fixed plate in a form of combination arrangement. The center of lower fixed plate is fixed on the driving pole of the musical bell; and the upper movable plate is mounted on a movable plate with a rotuberant pillar standing in its center. The main characters are: when the switch of the musical bell is start out, delightful musical rhythm is sounded so that its drivingpole starts out drive the lower fixed plate to turn around in circular movement; then, the permanent magnets fixed on the upper part of the ower fixed plate drives the permanent magnets fixed on the lower part of the upper movable plate, which in combination arrangement, thus enabling the doll or flowers and tree fixed on the movable plate to turn round and round in solid circular movement so that the water ball can play in various figures, giving a life-like effect.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
204 words
A water ball mechanism having a base member and an outer substantially transparent housing containing a figure adapted for rotative displacement comprising: (a) rotational drive means fixedly secured to said base member, said rotational drive means having a drive pole member being rotationally displaced; (b) a fixed plate member secured to said drive pole member, said fixed plate member having a first set of permanent magnets mounted therein; (c) a sliding plate vertically aligned with respect to said fixed plate and being rotationally displaceable, said sliding plate having a ring shaped groove formed within an upper end thereof; (d) a movable plate having a downwardly extending flange inserted within said ring shaped groove of said sliding plate, said movable plate being rotationally displaceable with respect to said sliding plate, said movable plate having a second set of permanent magnets mounted in a lower end section thereof for magnetic coupling with said first set of magnets mounted within said fixed plate; and, (e) a tubular member fixedly secured to a lower end portion of said figure and extending through a plurality of central through openings formed in said movable plate and said sliding plate, said tubular member being threadedly secured to a coupling nut member.
