Abstract
Abstract A toy music box including a table having an ornament. The table is journaled in a freely rotatable manner and is rotated by the mechanism of the music box. The toy music box is designed such that a rod is journaled in a freely rotatable manner on the table at a position on the side and apart from a rotational shaft of the table, a free end of the rod is projected outside of the table to mount ornaments. The free end of the rod is constantly energized in the rotational direction of the table by an interposed spring, and a protruded part on the lower side of the rod is abutted against a plurality of projected edges erected on the upper periphery of the platform. The ornaments on the turntable and the rod make interesting movements with each other.

A toy music box wherein a table having an ornament is rotatably coupled to a stationary platform and rotated by being driven in a first rotational direction relative to said platform by a driving means within said music box, the toy music box being characterized by: a rod having one end rotatably coupled to said table at a point eccentric to the axis of rotation of said table, another end of said rod extending out beyond the edge of said table; an ornament coupled to said another end of said rod; a spring means attached to said table and coupled to said one end of said rod to bias said another end of said rod relative to said table in said first rotational direction; a protrusion attached to said rod; and means including a plurality of protrusions provided on said platform for selectively engaging with said protrusion on said rod; whereby said rod cyclically is stopped from rotating with said table in said first direction by said protrusion on said rod engaging with one of said plurality of protrusions on said platform as said base rotates and is then released after a predetermined rotation of said table to rotate in said first rotational direction, moving at first relative to said table and then therewith until said protrusion on said rod engages with another of said plurality of protrusions on said platform.
