  Then, as shown in FIG. 10, a radial uneven surface 37 centered on the shaft hole 53 is formed at the intermediate base portion of the left and right arm bodies 26, 27 and the left and right leg bodies 32, 33. A radial concavo-convex surface 38 that engages and disengages is formed around the shaft hole 54 at the top of each tip portion 36, and each tip portion 36 is provided at the intermediate base of the left and right arm bodies 26, 27 and left and right legs 32, 33, respectively With the concavo-convex surfaces 37 and 38 joined, the pivot shaft 40 inserted through the shaft holes 53 and 54 and the nut 55 screwed into the pivot shaft 40 are joined so as to be rotatable. A spring 56 is wound so that the uneven surface 38 is pressed against the uneven surface 37 of the intermediate base.

  Each of the intermediate bases of the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 is formed with a projecting portion 41 that fits and holds the circular upper end portion of the tip portion 36 so as to be rotatable. The rotation range of the distal end portion 36 is restricted by the notched opening edges 42 and 43 of the portion 41. The left and right arm bodies 26 and 27 and the right leg body 33 can be turned inward by 45 °, and the left leg body 32 can be turned inward by 72.5 °.

  And the front end surfaces of the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 are formed on the ground surface 44 in a substantially right angle, and the left and right arm bodies 26, 27 and an engaging portion 46 that removably engages the rod-like body 45 with the left and right leg bodies 32 and 33 are formed, and the left and right arm bodies 26 and 27 and the distal end portions 36 of the left and right leg bodies 32 and 33 are substantially linear. It is possible to stand upright by grounding the tip grounding surface 44 in the extended state.

  As shown in FIG. 3, a head 47 is pivotally supported on the toy body 1 by a shaft 48, and one end of a link 49 is pivotally supported by a pivot 51 on the head 47. The other end of the link 49 is pivotally supported on a crank arm 50 of a crankshaft to which a gear meshing with a reduction output gear 9 of a reduction gear mechanism 8 provided on the machine frame 2 is attached. Further, a whistle body (not shown) provided on the toy body 1 has a whistle structure (not shown), and when the head 47 is turned up and down around the shaft 48 by the lifting and lowering operation of the link 49, the support shaft 51 performs the whistling operation. It is supposed to let you.

  Next, the operation of this embodiment will be described.

  As shown in FIGS. 2, 3, 6, and 7, the toy body 1 starts from a state in which the left and right arm bodies 26 and 27 of the toy body 1 and the tip portions 36 of the left and right leg bodies 32 and 33 are linear. And the left and right arm bodies 26, 27 and the left and right leg bodies 32, 33 as shown in FIGS. Fold inward of each other.

  When the distal end portions 36 of the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 are bent, the joint surface between the intermediate base portion of the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 and the upper end portion of the distal end portion 36 is Since the concave and convex surfaces 37 and 38 are formed radially with the shaft hole as the center, the distal end portion 36 is securely held by the urging force of the spring 56 in a bent state.

  Further, the bending angle of the distal end portion 36 is regulated by the notch opening edge 43 of the protrusion 41 formed at the intermediate base portion of the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33, for example, the left and right arm bodies 26 and 27 The right leg 33 is restricted to be bent inward by 45 °, and the left leg 32 is restricted to be bent inward by 72.5 °.

  Next, the toy body 1 in which the left and right arm bodies 26 and 27 and the distal end portions 36 of the left and right leg bodies 32 and 33 are folded is formed on the left and right arm bodies 26 and 27 and the distal end portion 36 of the left leg body 32 in an inverted state. The engaging portion 46 is engaged with the rod-like body 45, and the toy body 1 is hung as shown in FIG. At this time, the engaging portion 46 of the distal end portion 36 of the right leg 33 is in a state of being lifted up without being engaged with the rod-like body 45.

  When the motor 3 of the drive mechanism is driven by a switch operation (not shown) in this state, the operation mechanism 6 is operated, the reduction output gear 9 of the reduction gear mechanism 8 is rotated, and the switching gear 11 meshed with the reduction output gear 9 The crankshaft 20 rotates forward by meshing with the final output gear 21, and the left and right arm bodies 26 and 27 pivotally supported on the crank arms 18 and 19 of the crankshaft 20 are rotated in the front-rear direction.

  Since the left and right arm bodies 26 and 27 are inserted into the long grooves 28 and 29 in the substantially vertical direction through the support shaft 30 that is supported by the machine frame 2, the left and right arm bodies 26 and 27 The guide 29 engages with the support shaft 30 and rotates in the front-rear direction while moving in the up-down direction.

  Since the crank arms 18 and 19 are formed with a phase angle of 180 °, the crank arm 18 or 19 is pivoted to the crank arm that rotates upward from the horizontal position, for example, the left crank arm 18. The supported left arm 26 rotates while lifting from the rod 45 toward the front, and the engaging portion 46 is engaged with the rod 45 when the crank arm 18 pivots downward from the horizontal position. The other crank arm, for example, the right crank arm 19 rotates downward from the horizontal position. At this stage, the engaging portion 46 of the right arm 27 pivotally supported by the crank arm 19 is moved to the rod 45. When the crank arm 19 is held in the engaged state and is rotated upward from the horizontal position, the engaging portion 46 is lifted from the rod 45 and is rotated toward the front side.

  The left and right arm bodies 26 and 27 are alternately rotated in the front-rear direction, and the left and right leg bodies 32 and 33 connected to the left and right arm bodies 26 and 27 by the interlocking arms 34 and 35 are also interlocked. The reciprocating rotation is repeated, and the engaging portion 46 of the left leg 32 is sequentially engaged with and disengaged from the rod-like body 45 in the forward direction. Since the right leg 33 is not engaged with the rod-like body 45 so as not to interfere with the left arm 26 and the left leg 32, the left arm 26 and the left leg 32 are smoothly rotated, The puppet moves like a rope while hanging on a rope.

  In the process of continuing the tightrope forward movement of the toy body 1, the switching gear 11 with a smaller number of teeth of the switching mechanism 10 meshing with the reduction output gear 9 rotates faster than the switching control gear 12, and the crankshaft 20 rotates forward. Sometimes, the switching operation projections 14 and 15 of both gears 11 and 12 are engaged from the inclined portion on the engagement start end side, the switching gear 11 is pressed, and the support shaft 13 that pivotally supports the switching gear 11 is Sliding against the urging force, the ends of the switching operation projections 14 and 15 of both gears 11 and 12 are engaged, and the switching control gear 12 has an axial direction opposite to the sliding direction of the support shaft 13 The forward gear 16 and the final output gear 21 are disengaged while the ends of the switching operation protrusions 14 and 15 are engaged with each other. Then, the switching gear 11 meshes with the reversing gear 22, and the crankshaft 20 is switched to the reversing rotation and reversing and rotating.

  When one of the crank arms 18 and 19, for example, the left crank arm 18 rotates upward from the horizontal position, the arm body 26 pivotally supported by the crank arm 18 moves to the rear side. The engaging portion 46 is engaged with the rod-shaped body 45 when the crank arm 18 is pivoted downward from the horizontal position, and the other crank arm, for example, The right crank arm 19 is rotated downward from the horizontal position, and the engagement portion 46 of the right arm 27 supported by the crank arm 19 is held in a state of being engaged with the rod-like body 45. At the stage of turning upward from the horizontal position, the engaging portion 46 is lifted from the rod-like body 45 and turned toward the rear side.

  As the left and right arm bodies 26 and 27 are alternately rotated to the left and right, the left and right leg bodies 32 and 33 connected to the left and right arm bodies 26 and 27 by the interlocking arms 34 and 35 are also interlocked to repeat the reciprocating rotation. The engaging portion 46 of the left leg 32 is sequentially engaged with and disengaged from the rod-like body 45 to the rear side. At this time, the right leg 33 does not interfere with the left arm 26 and the left leg 32, the left arm 26 and the left leg 32 are smoothly rotated, and animals, dolls, etc. It shows the action of hanging the rope and hanging it backwards.

  Further, while the reverse operation is continued, the switching gear 11 rotates faster than the switching control gear 12, and when the engagement of the switching operation protrusions 14 and 15 between the switching gear 11 and the switching control gear 12 is released, The support shaft 13 is returned and slid by the urging force of the spring 17, the meshing of the switching gear 11 and the reverse gear 22 is released, and the crankshaft 20 is rotated forward by the meshing of the forward gear 16 and the final output gear 21, Again, it becomes a forward tightrope movement.

  Further, the left and right arm bodies 26 and 27 engaged with the rod-like body 45 and the engaging portion 46 of the left leg body 32 are removed from the rod-like body 45, and as shown in FIGS. With the distal ends of the left and right legs 32, 33 straightly extended, the left and right arms 26, 27 and the left and right legs 32, 33 are in contact with the table, floor, etc., as shown in FIGS. When the ground 44 is placed and the motor 3 of the drive mechanism is driven in this state, the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 are alternately moved back and forth by the rotation of the crankshaft 20 as described above. The toy body 1 rotates forward in a direction and exhibits a forward walking motion.

  As described above, the switching mechanism 10 that meshes with the reduction output gear 9 operates to switch between the switching gear 11 and the switching control gear 12 while the forward walking operation is performed by the rotation of the crankshaft 20. Due to the engagement with the operating projections 14 and 15, the crankshaft 20 is switched to reverse rotation and reverse rotation, and the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 are repeatedly rotated alternately left and right, and the toy body 1 exhibits a backward walking motion.

  As shown in FIG. 11, the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 are repeatedly rotated in the front-rear direction alternately to ensure the operation that the toy body 1 exhibits a forward walking motion. In a state where the distal end portions of the left and right arm bodies 26, 27 and the left and right leg bodies 32, 33 are inclined substantially linearly toward the outside, for example, in a state where the distal end portion 36 is inclined 22.5 ° toward the outside, The toy body 1 can be prevented from falling.

  In the above embodiment, during the tightrope movement, the right leg 33 is lifted without the engaging portion 46 engaging the rod 45, but the left leg 32 is lifted from the rod 45. Thus, the bending angle of the right leg 33 can be made larger than that of the left leg 32.

  Further, in the above-described embodiment, the configuration for performing the tightrope movement and the walking operation has been described. However, in the configuration in which the walking operation is not performed, the left and right arm bodies 26 and 27 and the left and right leg bodies 32 and 33 are fixed in a bent state. It can also be.

  Further, the rod-like body 45 can be used as the rod-like body 45 by being tensioned and stretched even with a string-like body, in addition to a metal rod body, a rod body molded with a synthetic resin, or the like.

  In the above-described embodiment, the electric motor 3 is used as the drive mechanism, but a configuration using a spring mainspring can also be used.
