The robot toy of the present invention mainly comprises a head 1, a trunk 2, arms 3, 4, legs 5, 6, feet 50, 60, and a trunk 2.
And a mechanism for transmitting the urging force of the mainspring unit 18. The mainspring unit 18 can be used as a drive source to interlock the right and left hip swing motion and the alternate arm swing motion of the arm. This is a robot toy characterized in that it can be configured as follows, and its specific mechanism will be described below.

First, the waist swing mechanism will be described.
When the mainspring is wound by the mainspring winding knob 19, the rotating shaft 7 of the mainspring unit 18 is rotated by the urging force of the mainspring, and the eccentric rotating disk 8 fixed to the rotating shaft 7 is rotated.

The eccentric rotary disk 8 is sandwiched between two swinging arms 9 and 10 which are swingably arranged on the front surfaces of the body 2 with the supporting shafts 13 and 14 as fulcrums. With the rotation of the core rotating disk 8, the swing arms 9, 10 swing, and the upper ends of the legs 5, 6 integrally fixed to the swing arms 9, 10 are attached to the feet 50. , 60 as a base point, a waving motion is given as shown in FIGS.

The two oscillating arms 9, 10 are urged inward by a coil spring 17 between the pins 11, 12 implanted in the oscillating arms 9, 10 to clamp the eccentric rotary disk 8. The support shafts 13 and 14 are provided with two swing arms 9 and 1
0 and the upper ends of the leg portions 5 and 6 are integrally fixed and are rotatable by the bearing portions 15 and 16, so that the left and right hip swing operations as described above can be performed.

Next, the mechanism for swinging the arms 3 and 4 will be described. When the mainspring is wound by the mainspring winding knob 19, the rotating shaft 7 of the mainspring unit 18 is rotated by the biasing force of the mainspring, and the eccentric rotating disk 21 on the rear surface fixed to the rotating shaft 7 is rotated.

A pin 2 planted at the tip of a cam 22 that is swingably disposed on the back of the body 2 with a support shaft 24 as a fulcrum.
3 has a central portion of the tex 20 fixed thereto, and both ends of the tex 20 are provided with respective elbow portions 30, 4 of the arms 3, 4, respectively.
The pin 23 implanted in the cam 22 is moved to the left and right through the eccentric rotating disk 21 and the cam 22 which are fixed to 0 and are rotated by the urging force of the mainspring unit 18 to move the Tegs 20. It is configured to be pulled left and right to give an arm swinging motion to the left and right arms 3 and 4 alternately.

The arm swing operation is clear from FIG.
The right arm 3 is positioned at the chest portion of the torso 2 by the support shaft 32 of the shoulder portion and the support shaft 31 of the elbow portion, whereas the right arm 4 is supported by the support shaft 42 of the shoulder portion and the support shaft of the elbow portion. These operations are alternately performed by the left and right movements of the tex 20 to be described above, and the arm swing operation is repeated.

[0013]

As described above, the present invention has a structure as described above. The right and left hip swing motion and the alternate arm swing motion of the arm portion can be interlocked by the urging force of one mainspring unit. It is possible to provide a robot toy that is robust, hard to break, can be manufactured at low cost, and can be easily enjoyed by infants.
