Abstract:
A motor operated toy is made to have a pair of moving cams which are synchronously driven to cause a swinging motion of the toy and is further formed with a pair of spring loaded feet for auxiliarily increasing the swinging motion of the toy as the toy moves across a supporting surface which is also engaged by the moving cams. A pair of crank operated limbs are also disclosed.

Description:
BACKGROUND OF THE INVENTION 
     Conventional animal toys are made movable, which are however, lacking of vividness as they can only walk in a mechanical way. 
     The present inventor has found the defect of conventional toy and invented the present vivid toy. 
     SUMMARY OF THE INVENTION 
     One object of the present invention is to provide a toy comprising a main body, a power driving means, a power transmitting means, a pair of alternative moving cams, and a pair of resilient feet, wherein the alternative moving cams are synchronously driven by the power driving means are respectively made as irregular corrugations along their perimeters which are not coincided superimposedly so that either cams may walk in a swinging and twisting way to become vivid for the present toy. 
     Another object of the present invention is to provide a toy comprising a pair of resilient feet, each foot is spring loaded which will make the toy walking with a waddle so as to increase the vividness of the toy. 
     Still another object of the present invention is to provide a toy wherein a pair of side-arm portions are respectively provided on either side of the main body and are respectively biased by a striking rod formed on a gear shaft of power transmitting means so as to swing the side-arm portions during walking to further increase the vividness.

     DETAILED DESCRIPTION 
     As shown in FIG. 1, the present invention comprises a main body 1, a power driving means 2 disposed in body 1, a power transmitting means 3 transferring the output force from power driving means 2, a pair of alternative moving cams 4, 4a receiving the output force through the transmitting means 3, and a pair of resilient feet 5 resiliently formed on the bottom portion of the toy. 
     Main body 1 comprises a casing for storing and forming the other parts of the present invention therein and may be made as any shape to imitate the true animals (human) or stocks. A head portion 11 with replaceable hat 11a and eyes 11b with flash lights provided thereafter is formed on the body 1. A spring 12 is also provided to make the swinging action of head portion 11 during walking of the toy. Of course, the head portion 11 of the present invention may be fixed on the body 1 without spring 12. 
     A pair of side-arm portions 13 are respectively formed on both sides of body 1, which may be formed as a wing of a duck as shown in FIG. 2. The side-arm portion 13 comprises an extension 13a inserted through a slit 13&#39; on body 1 and free engaged thereon, and a strike-receiving plate 13b which is biased by a striking rod 3b formed on the shaft 3a of power transmitting means as shown in FIG. 3. 
     Power driving means 2 comprises a sound-wave receiver 21, a sound-actuated controller 22, a power source 23, a motor 24 and a driving gear 25. Such a power driving means 2 is actuated by receiving a sound wave such as from hand-clapping. Once starting the power driving means 2, a time delayed circuit will allow continuous moving of the present invention during a pre-set time interval. Naturally, other power systems such as those spring-actuated or battery operated or any other remote control or any other systems may also be used in the present invention. 
     Power transmitting means 3 is practically a speed-reducing gear set which serves to reduce the rotation speed of the power driving means 2. A final cam gear 41a is engaged with a gear of power transmitting means 3. Such cam gear 41a is connected on a cam shaft 41 which is fixed with the alternative moving cams 4, 4a. 
     Alternative moving cams 4, 4a are respectively made as irregular corrugations along their perimeters which are not coincided superimposedly as FIG. 4 shown. Such pair of moving cams 4, 4a are synchronously driven by power driving system 2 through power transmitting system 3. The cam 4, 4a is directly walking on ground G. 
     Resilient feet 5 are positioned on both sides of the bottom portion of the present invention, each comprising a foot portion 50, a supporting leg 51, a helical spring 52 backing the supporting leg 51, and a jacket pipe 53 jacketing the spring 52 and leg 51 and formed on the body 1. 
     When playing the present invention, the power driving means 2 is first actuated to operate the alternative moving cams 4, 4a. The corrugations formed on each cam 4 or 4a are not superimposed as FIG. 4 shown. Hence, during walking, the left cam 4 and the right cam 4a will move the gravity center of the present invention either rightwards or leftwards to cause the swinging motion of the present invention. If the cam is made flat as FIG. 5b shown, the present invention will move in a straight line. However, if the cam is twisted in shape as observed from its projective sideview as FIG. 5c shown, the present invention will walk in a twisting way like a snake. The afore-mentioned swing and twisting motion of the present invention will greatly increase the vividness of the imitated animals so as to spur the players&#39; interest. 
     During rotating the shaft 3a, the side-arm portions 13 are biased either horizontally (H) or vertically (V) to imitate the action of duck&#39;s wing to further increase the lovely feature of the present invention. 
     The resilient feet 5 are provided to auxiliarily increase the swinging motion of the present invention. This can be easily understood, for example, when the cam is rotated from the extended corrugation to the recess corrugation on the cam perimeter, the sudden drop by body gravity will counteract the spring 52 jacketed in pipe 53 to form a resilient force to vibrate the feet 50. Such vibration of feet will magically resemble the walking with a waddle to increase more vividness of the present invention. The spring 52 also serves as safety buffer when accidently dropping the present invention to protect the present invention. 
     FIG. 6 shows another preferred embodiment which is made as a gliding egg moving in a twisting way and sweeping its wings 13 to increase its fantastic feeling for the player&#39;s interest. 
     FIG. 7 shows still another preferred embodiment which is made as a twisting snake moving in a twisting way T. 
     FIGS. 8, 9 and 10 respectively show the features of santa claus, a witch and a pirate. During the swinging walking of the features by cams 4, 4a, the side-arm portions (hands) 13 are also sweeping and the heads 11 are swinging to greatly increase the vividness.
