Abstract:
A swinging structure for a mechanical animal adapted for use to facilitate swinging movements of mechanical animals of any shape, said swinging structure comprising:a housing having a receiving chamber in which a shaft and a rod are disposed, said rod being disposed substantially perpendicular to said shaft; an eccentric wheel provided on said shaft adjacent to an intermediate section thereof; a worm gear provided on said shaft and to one side of said eccentric wheel; a worm provided on said rod and engageable with said worm gear such that when a transmission device provided at one end of said rod is actuated, said worm, said worm gear and said eccentric wheel can be brought to rotate relative thereto; at least one post provided on an outer wall of said housing proximate to said eccentric wheel; a T-shaped actuated plate having one end in the form of an elongated groove fitted on said at least one post and the other end extending substantially perpendicular to said elongated groove and provided with a pin, the other side of said elongated groove extending substantially perpendicular and provided with a notch that can just accommodate an outer edge of said eccentric wheel; a shell having an outer wall provided with an actuated rod corresponding to said pin of said actuated plate, said actuated rod being in the form of an elongated groove and disposed substantially perpendicular to said elongated groove of said actuated plate; whereby said swinging structure is adapted to be disposed on a frame of a the mechanical animal such that when said eccentric wheel rotates, through said notch that moves along said outer edge of said eccentric wheel, said actuated plate can oscillate within said elongated groove thereof so that said pin on said actuated plate can actuate said actuated rod along said elongated groove thereof to cause said shell to perform left and right oscillation.
