Motion toy

Abstract

A motion toy is constructed to include a body, a head, a tail, and a power drive unit mounted in the body and coupled between the head and the tail, the head having a beak, the power drive unit including a motor, a transmission gear train coupled to the motor, a reciprocating rod driven by the transmission gear train to close/open the beak of the head, a first coupling driven by the transmission gear to turn the shell of the head alternatively leftwards and rightwards, and a second coupling coupled to the first coupling and driven to turn the tail alternatively up and down.

What the invention claimed is:  
     
         1 . A motion toy comprising a body, a head, a tail, and a power drive unit mounted in said body and coupled between said head and said tail, wherein said head comprises a shell, a beak mounted in the shell of said head, said beak comprising an upper mandible fixedly fastened to the shell of said head, a lower mandible pivoted to the shell of said head below said upper mandible and supported in a close position closed on said upper mandible, said lower mandible having a rear extension, a press plate pivoted to the shell of said head and stopped at the rear extension of said lower mandible and adapted for turning said lower mandible relative to said upper mandible, and a swivel plate coupled to the shell of said head and adapted for turning the shell of said head alternatively leftward and rightward; said power drive unit comprises a casing, a motor mounted in said casing, a transmission gear train mounted in said casing and coupled to said motor, a reciprocating rod coupled to said transmission gear train and driven by said transmission gear train to move said press plate of said head, a first coupling coupled to said transmission gear train, and a second coupling coupled to said first coupling and driven by said first coupling to turn said tail alternatively up and down upon motion of said motor.  
     
     
         2 . The motion toy as claimed in  claim 1 , wherein said first coupling comprises a longitudinal center sliding slot coupled to said transmission gear train and alternatively moved back and forth by said transmission gear train upon motion of said motor, two transverse sliding slots disposed at two sides of said longitudinal center sliding slot and respective coupled to a respective locating block of said casing, a rear rod coupled to a coupling notch of said second coupling for driving said second coupling to turn said tail up and down, and a front bottom rod coupled to a bottom coupling notch of said swivel member of said head for turning said swivel member and the shell of said head upon motion of said motor.  
     
     
         3 . The motion toy as claimed in  claim 2 , wherein said transmission gear train comprises a first gear fixedly fastened to an output shaft of said motor, a second gear, a third gear coupled to said first gear through said second gear, said third gear having an eccentric rod adapted to reciprocate said reciprocating rod, a fourth gear meshed with said third gear, and a wheel connected to said fourth gear for synchronous rotation with said fourth gear, said wheel comprising an eccentric rod coupled to the longitudinal center sliding slot of said first coupling,  
     
     
         4 . The motion toy as claimed in  claim 3 , wherein said head further comprises a circular bottom cover plate coupled to an inside annular groove of the shell of said head, a limiter block fixedly mounted on said circular bottom cover plate in vertical, said limiter block comprising a smoothly arched sliding slot; said swivel member is inserted through an opening of said circular bottom cover plate, having one end coupled to the front bottom rod of said first coupling and an opposite end provided with a fixed guide rod coupled to the smoothly arched sliding slot of said limiter block.  
     
     
         5 . The motion toy as claimed in  claim 1 , wherein said lower mandible comprises a hook connected to a post inside the shell of said head by spring means, which holds said lower mandible in an upper limit position closed on said upper mandible.  
     
     
         6 . The motion toy as claimed in  claim 2 , wherein said tail comprises a base plate, said base plate having two parallel coupling blocks, an N-shaped link pivoted to said base plate, said N-shaped link comprising a center coupling rod pivotally coupled to the coupling blocks of said base plate, a front end coupled to the second coupling of said power drive unit, and an end coupling rod extended from a rear end thereof, a coupling plate coupled to said N-shaped link, said coupling plate comprising an elongated coupling slot disposed in one end thereof and coupled to the end coupling rod of said N-shaped link and coupling rod disposed at an opposite end thereof, and an end piece, said end piece having a coupling portion pivotally coupled to the coupling rod of the coupling plate of said tail, and a return spring mounted on the coupling rod of the coupling plate of said tail and connected between the coupling plate and end piece of said tail.  
     
     
         7 . The motion toy as claimed in  claim 1 , wherein the front end of said N-shaped link comprises a trapezoidal end coupling notch coupled to a coupling rod of said second coupling of said power drive unit.  
     
     
         8 . The motion toy as claimed in  claim 1  further comprising a recording device mounted in said body for recording sound, said recording device having a hinged cover.  
     
     
         9 . The motion toy as claimed in  claim 1  further comprising two wings respectively pivoted to said body at two sides.
