The rocking board 8 is swayably mounted in the inside of the body 1 and has an upper end pivoted on the shoulder 2 , and a lower end pivoted on the bottom plate 14 of the body 1 by a bottom axle S 0 .

The main swayable mechanism 9 as shown in FIG. 4 includes a motor M mounted on one side of the rocking board 8 and having an output shaft S 1 protruding outward from the rocking board 8 . A small belt wheel 91 is secured on the output shaft S 1 of the motor M. A large belt wheel 92 is rotatably mounted on the rocking board 8 by a shaft S 2 , and is located under the small belt wheel 91 . A belt 93 is mounted between the large belt wheel 91 and the small belt wheel 92 for transmitting the output power of the motor M. A first pinion 94 is mounted on the shaft S 2 to rotate with the large belt wheel 92 . A first large gear 95 is rotatably mounted on a shaft S 3 , and meshes with the first pinion 94 to rotate therewith. A second pinion 96 is integrally formed with the first large gear 95 to rotate therewith. A second large gear 97 is secured on a first end of the bottom shaft S 0 of the rocking board 8 , and meshes with the second pinion 96 to rotate therewith. An eccentric wheel 98 is secured on a second end of the bottom shaft S 0 to rotate with the second large gear 97 , wherein the second end of the bottom shaft S 0 extends through the rocking board 8 and an upright plate 141 of the bottom plate 14 . A cam 99 is mounted on the upright plate 141 of the back of the rocking board 8 , and defines an oblong cam slot 991 for receiving the eccentric shaft 98 .

Horizontal guide track devices 992 and 142 are mounted between the cam 99 and the upright plate 141 , and the cam 99 has two sides each provided with an extension 994 having a hook 993 hooked on a pin 33 of the upper portion of the leg 3 . An elastic detent 143 is mounted on the upright plate 141 of the bottom plate 14 for retaining the cam 99 to prevent from detachment of the cam 99 . A catch plate 995 is mounted on the cam 99 for preventing the eccentric wheel 98 from being detached from the bottom shaft S 0 . The belt wheels 91 and 92 , and the gear sets 94 and 95 construct the speed reduction gear set 90 . Two tension springs 996 are mounted on the back of the rocking board 8 for facilitating operation of the swayable mechanism.

When the motor M is rotated, the eccentric wheel 98 is rotated with the large gear 97 whose speed is reduced by the speed reduction gear set 90 . The cam 99 is moved by the eccentric wheel 98 co-operating with the cam slot 991 so that the two extensions 994 will push each of the legs 3 to pivot about the pivot axle P 3 by means of the hook 993 co-operating with the pin 33 .

When each of the legs 3 oscillates, the bottom plate 14 pivoted on the legs 3 by the pivot axle P 1 is moved with the legs 3 . The rocking board 8 pivoted on the bottom plate 14 by the bottom shaft S 0 will oscillate due to the resistance of the springs 996 as shown in FIG. 7 .

As shown in FIGS. 1 , 5 and 6 , the arm swayable mechanism 10 includes a pair of symmetrical axle members 10 a each pivotally mounted in the bearings 23 and 24 of the shoulder 2 , and a pair of symmetrical push/pull bars 10 b each including an upright bar portion 121 secured on a U-shaped forked portion 101 of the axle member 10 a, and a horizontal bar portion 122 slidably mounted on a pin 81 of the rocking board 8 by a transverse slot 123 .

The axle member 10 a has an inner end provided with an axle end 102 , and an outer end provided with a hollow axle end 104 having an elastic pawl 103 . A cam 105 is located adjacent to the forked portion 101 . The axle member 10 a is made of two pieces which are integrally coupled by screws 106 .

When the rocking board 8 is rocked with the body 1 in an inclined manner, the heights of the pins 81 are made different from each other. As shown in FIG. 7 , the higher pin 81 pushes the mating push/pull bar 10 b upward, and the lower pin 81 pushes the mating push/pull bar 10 b downward. The two axle members 10 a are pushed by the two push/pull bars 10 b through the forked portion 102 to rotate around a circle along the clockwise direction and the counterclockwise direction respectively as shown in FIGS. 6B and 6C . in such a manner, the legs 4 connected to the hollow axle portion 104 of the axle member 10 a are oscillated with the rocking board 8 .

When the axle members 10 a are rotated by pushing the push/pull bar 10 b, the cams 105 are rotated simultaneously. Each of the cams 105 has a top rested on a wing 54 of the eye ring 53 which is supported on a support member 52 of the head 5 . In such a manner, when the pair of cams 105 are rotated along different directions, the wing 54 is driven to move the head 5 so that the head 5 is pivoted with the arms 4 about a pivot axle P 4 .

Basically, the distance between the pivot axle P 1 and the pivot axle P 3 is greater than that between the pivot axle P 1 and the pivot axle P 2 . In addition, the distance between the two pivot axles P 1 is equal to that between the two pivot axles P 3 , and is greater than that between the two pivot axles P 2 . In such a manner, P 1 , P 3 , P 3 and P 1 construct a parallelogram, and P 1 , P 2 , P 2 and P 1 construct a trapezoid so that when the legs 3 and the body 1 sway, the shoulder 2 is caused to move upward and downward as shown in phantom lines in FIG. 7 .

The joint a 1 includes a ratchet wheel 43 rotatably mounted in the hollow axle portion 104 and locked by the elastic pawl 103 , an annular element 45 mounted on the other end of the ratchet wheel shaft 43 a to rotate relative to the upper arm portion 41 by a shaft 44 and having a locking pawl (not shown), and a semi-circular ratchet wheel 46 formed in the upper arm portion 41 and locked by the locking pawl. The joint a 2 includes a plug element 47 secured in the lower arm portion 42 , and a semi-circular ratchet wheel 48 rotatably inserted into the lower arm portion 42 by a shaft 44 a and locked by a locking pawl 49 which is mounted in the lower arm portion 42 .

The rocking board 8 has a lower portion having two symmetrical pins 15 each slidably mounted in a guide slot of an arcuate cam 35 formed on an upper portion of each of the arms 3 .

In operation, referring to FIGS. 7 and 8 , when the motor M is rotated, the torque of the motor M is transmitted through the belt wheel 91 , the belt 93 , the belt wheel 92 , the gears 94 , 95 , 96 and 97 , and the shaft S 0 to the eccentric wheel 98 which is eccentrically rotated in the cam slot 991 of the cam 99 so as to push the cam 99 to move in the guide track devices 992 and 142 reciprocally. The legs 3 are pushed and pulled by the two extensions 994 of the cam 99 to oscillate about the pivot axle 3 in an inclined manner. The two side plates 13 are pivoted about the pivot axle P 1 to oscillate in the other direction. The bottom plate 14 pivoted on the pivot axle P 1 , the rocking board 8 pivoted on the bottom shaft S 0 , the front cover plate 11 mounted on the front side of the rocking board 8 , and the rear cover plate 12 mounted on the rear side of the rocking board 8 are oscillated in the same direction while the shoulder 2 pivoted on the two side plates 13 and the rocking board 8 by the pivot axles P 2 and P 5 is also oscillated therewith. At the same time, the two arms 4 are also oscillated by actuation of the arm swayable mechanism 10 while the head 5 is moved by the cam 105 of the arm swayable mechanism 10 to pivot about the pivot axle P 4 along a direction different from that of the shoulder 2 .

In such a manner, when the legs and the waist of the toy are oscillated, the shoulder, the arms and the head can also be oscillated at the same time, thereby increasing the active amusement of the toy.

It should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
