Abstract
The invention relates to the driving mechanism of multi-action doll. The driving mechanism comprises an eccentric roller, a cross-shaped driving component and several driving gears. The cross-shaped driving component has a rectangular hole which accommodates the eccentric roller which moves the cross-shaped driving component back and forth in a linear direction when the roller rotates in the hole. The cross-shaped driving component has racks that mesh with and rotate the driving gears when the driving component is moved by the eccentric roller. Rotation of the gears also rotates shafts on the gears which convey motion to selected portions of a moveable doll.
Claims9
A driving mechanism for producing selected movement in a doll, said mechanism comprising,
- an upper housing (32) having first guiding blocks (322) and at least one first gear seat (323),
- a bottom plate (31) having second guiding blocks (312) and at least one second gear seat (313) concentric to said first gear seat (313),
- a cross-shaped driving component (34) having a front fin (342) and a rear fin (343) and a rectangular hole (341) between said front fin (342) and said rear fin (343),
- an upper and a lower surface of each of said front fin (342) and said rear fin (343) having a groove (344, 345) respectively corresponding to said first guiding blocks (322) and said second guiding blocks (312),
- at least one side of said cross-shaped driving component (34) having a driving rack (3461-3466),
- wherein said groove on said upper and said lower surface of each of said front fin and said rear fin of said cross-shaped driving component are respectively slidably engaged by said first guiding blocks and said second guiding blocks when said upper housing (32) is engaged to said bottom plate (31),
- an eccentric roller (33) driven by a motor (2) engaged to a bottom side of said bottom plate (31),
- said eccentric roller (33) in sliding engagement with sides of said rectangular hole (341) to produce back and forth linear sliding movement of said cross-shaped driving component (34) as said motor rotates said eccentric roller,
- opposing ends of at least one gear (351-354) rotatably mounted in said at least one first gear seat and said at least one second gear seat,
- said at least one gear (351-354) rotatably driven by said driving rack (3461-3466) as said eccentric roller (33) slidably drives said cross-shaped driving component, and
- doll actuating means engaged to said at least one gear for moving selected portions of said doll when rotated by said at least one gear (351-354).
