BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a motion toy and, more particularly, to such a motion toy, which rotates the head alternatively forwards and backwards and turns the beak alternatively up and down when one passed by.  
           [0003]    2. Description of the Related Art  
           [0004]    A variety of toys are commercially available. In order to attract children&#39;s attention, motion toys are developed instead of stationary toys. Regular motion toys are commonly designed to move the head and the limbs when switched on. These motion toys are less attractive because they cannot be automatically triggered to move.  
         SUMMARY OF THE INVENTION  
         [0005]    The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a motion toy, which automatically rotates the head alternatively forwards and backwards and turns the beak alternatively up and down when one passed by. It is another object of the present invention to provide a motion toy, which produces sound when triggered to move the head and the beak. According to one aspect of the present invention, the motion toy comprises a base, a body supported on the base, a swivel head coupled to the body at a top side, the head having a beak pivoted thereto, a power drive mounted inside the body and adapted to rotate the swivel head alternatively forwards and backwards and to turn the beak alternatively up and down, and sensor means installed in the base and controlled to drive the power drive. According to another aspect of the present invention, speaker means is installed in the body and controlled by the sensor means to produce sound upon operation of the power drive.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0020]    Referring to FIGS. 1, 2,  3 ,  3 A,  3 B, and  4 , a motion toy in accordance with the present invention is shown comprised of a body  1 , a head  2 , a base  3 , and a power drive  4 .  
         [0021]    The body  1  comprises a hollow shell  11  formed of two symmetrical halves abutted against each other, and a speaker  12  mounted inside the hollow shell  11 . The hollow shell  11  has a top coupling groove  111 .  
         [0022]    The head  2  comprises a hollow shell  21  formed of two symmetric halves abutted against each other, the hollow shell  21  having a bottom coupling groove  211  and a plurality of inside locating rods  212 , a beak  22  pivoted to one inside locating rod  212  and extended out of the hollow shell  21 , a stop plate  221  perpendicularly downwardly extended from the inner end of the beak  22 , a hook  222  perpendicularly backwardly extended from the back side of the stop plate  221 , and a spring  5  connected between the hook  222  and one inside locating rod  212 .  
         [0023]    The base  3  comprises two sensors  31  bilaterally disposed at the front side.  
         [0024]    The power drive  4  comprises a transmission mechanism  41 , a holder  42 , a rotary cap  43 , and a motor  44 . The motor  44  is mounted in the bottom side of the casing  410  of the transmission mechanism  41 , having a drive wheel  441  fixedly mounted on the output shaft thereof. The transmission mechanism  41  comprises a driven gear wheel  411 , a transmission belt  6  coupled to the drive wheel  441  and the driven gear wheel  411 , a first transmission gear  412  meshed with the driven gear wheel  411 , a second transmission gear  413  meshed with the first transmission gear  412 , a third transmission gear  414  meshed with the second transmission gear  413 , an output gear  415  fixedly mounted on the gear shaft  7  of the second transmission gear  413 , and an output wheel  416  fixedly mounted on the gear shaft  7  of the third transmission gear  414 . The output wheel  416  has an eccentric rod  4161 . The holder  42  is fixedly fastened to the topside of the casing  410  of the transmission mechanism  41  by fastening elements, for example, screws  8 , comprising through holes  421 ; 423 , and a plurality of upright guide rods  422 . The rotary cap  43  is revolvably supported on the holder  42 , comprising a center through hole  432  and two opposite arched slots  431  respectively coupled to the upright guide rods  422  of the holder  42 , an internal gear  433 , a plurality of upright rods  434 , and a locating plate  45  coupled to the upright rods  434 . The locating plate  45  has a slot  451 . The aforesaid output gear  415  is inserted through the through hole  421  of the holder  42  and meshed with the internal gear  433 . The aforesaid output wheel  416  is inserted through the through hole  423  of the holder  42  and the through hole  432  of the rotary cap  43  with the eccentric rod  4161  coupled to the slot  451  of the locating plate  45 . Therefore, rotating the output wheel  416  causes the rotary cap  43  to be alternatively rotated forwards and backwards and the locating plate  45  to be reciprocated back and fro.  
         [0025]    During assembly process, the holder  2  is coupled to the top coupling groove  111  of the hollow shell  11  of the body  1 , and then the bottom coupling groove  211  of the hollow shell  21  of the head  2  is coupled to the rotary cap  43 , keeping the locating plate  45  stopped against the back side of the stop plate  221 , and then the body  1  is fixedly mounted on the topside of the base  3 , keeping the motor  44  electrically connected to the sensors  31 .  
         [0026]    Referring to FIGS. 5, 6,  6 A,  7 ,  7 A,  8 ,  8 A, and  8 B, the sensors  31  respectively control the motor  44  to rotate forwards or backwards. When started the motor  44 , the drive wheel  441  is turned to rotate the driven gear wheel  411  through the transmission belt  6 , thereby causing the transmission gears  412 ; 413 ; 414  to be rotated. During rotary motion of the transmission gears  412 ; 413 ; 414 , the output gear  415  is synchronously rotated with the second transmission gear  413  to further rotate the rotary cap  43  and the head  2 , and the output wheel  416  is synchronously rotated with the third transmission gear  414 , causing the eccentric rod  4161  to reciprocate the locating plate  45  back and fro. During forward movement of the locating plate  45 , the locating plate  45  pushes the stop plate  221 , thereby causing the beak  22  to be turned upwards to stretch the spring  5 . During backward movement of the locating plate  45 , the spring  5  pulls the hook  222  downwards to return the beak  22  to its former position. Further, the beak  22  can be made having a fixed lower mandible fixedly fastened to the head  2  and an upper mandible pivoted to the head  2 , so that the upper mandible is alternatively turned up and down relative to the lower mandible upon reciprocating motion of the locating plate  45 .  
         [0027]    When the user passed by to trigger the sensors  31  in one direction, the sensors  31  drive the motor  44  to rotate clockwise, thereby causing the head  2  to be turned in the same direction, and at the same time the speaker  12  is driven by the sensors  31  to produce sound. On the contrary, when the user passed by to trigger the sensors  31  in the reversed direction, the sensors  31  drive the motor  44  to rotate counter-clockwise, thereby causing the head  2  to be turned in the reversed direction, and at the same time the speaker  12  is driven to produce sound.  
         [0028]    Furthermore, the base  3  can be directly formed integral with the body  1 .  
         [0029]    A prototype of motion toy has been constructed with the features of the annexed drawings of FIGS.  1 - 8 . The motion toy functions smoothly to provide all of the features discussed earlier.  
         [0030]    Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
