(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral A indicates a swing motion device in a toy according to the present invention. This swinging device A includes a swinging member 2 provided in a casing 1, a drive mechanism a for swinging the swinging member 2, and an operating shaft supported on the casing 1 so that one end thereof projects outside. 3.4.5
The operating shaft 3.4.5 and the swinging member 2 are formed to interlock with each other.

The swinging member 2 has a substantially semicircular shape, and is attached to the center portion of the casing body 1 via a support shaft 6 so as to be swingable in the left-right direction.

A toothed portion 2a is carved on the outer periphery of the swinging member 2, and a guide groove 7 is formed from the center of the lower part toward the support shaft 6.

The operating shaft 3.4.5 is supported by bearing parts 9.9.9 formed at the center of the upper part and upper parts of both sides inside the casing 1, and one end of the bearing part 9.9.9 projects to the outside of the casing 1.

A spur gear 11 is fixed to the other end of the operating shaft 3, and a bar member 12, 12 is disposed inside thereof so as to be movable up and down. That is, this rod member 12.12 is loosely fitted inside the through holes 3a, 3a passed through in the longitudinal direction of the operating shaft 3, and both ends of the rod member 12.12 protrude from the operating shaft 3. At the same time, the bulging portions 1.2a and 12a provided near the bottom prevent it from coming off.

Next, the operating shaft 4.5 is connected to the front members 4a, 5a and the rear member 4.
A shaft member 13 is loosely fitted inside the shaft member 13, and stoppers 13a, 13a are provided at both ends of the shaft member 13. Thereby, the operating shaft 4.5 is supported by the shaft member 13 so as to be rotatable in forward and reverse directions. Further, spur gears 15.15 are fixed to the rear members 4b, 5b near the other ends, and flat end surfaces 16 are notched in the rear members 4b, 5b located outside the spur gears 15.15. .16 is formed. The base end of the rod member 12.12 is always in contact with the flat surface 16.16.

The drive mechanism a includes a first gear part and a second gear part. That is, the first gear portion includes a spur gear 21 and a mainspring 22 fixed to a drive shaft 20, a pinion 24 fixed to a support shaft 23 that meshes with the spur gear 21, and a support that can freely engage and detach from the pinion 24. Pinion 2 fixed to shaft 25
6, a pinion 29 fixed to a support shaft 28 meshed with a spur gear 27 arranged in parallel with the pinion 26, and a pinion 29 fixed to a support shaft 31 meshed with a spur gear 30 arranged in parallel with the pinion 29. a pinion 32, an ankle 35 fixed to a support shaft 34 that is removable from a spur gear 33 arranged in parallel with the pinion 32, and a pinion 37 fixed to a support shaft 36 meshed with the pinion 29; It is formed by a pinion 39 fixed to a support shaft 38 that meshes with the pinion 37, and an oval cam 4° arranged in parallel with the pinion 39 and eccentrically attached to the support shaft 38. . The cam 40 is loosely fitted into the guide groove 7 formed in the swinging member 2. Thereby, by rotating the first gear portion, the swinging member 2 can be caused to swing about the support shaft 6 as a fulcrum.

One end of the mainspring 22 wound around the drive shaft 2o in the first gear portion is fixed to the drive shaft 2o, and the other end is fixed to a predetermined position on the casing 1. Further, one end of the drive shaft 2o is projected toward the surface side of the casing 1, and a string wheel 42 is fixed thereto.
A string 43 is wrapped around the string 43. Furthermore, the support shaft 23 of the pinion 24 is supported by a long hole 44, 44, and when the mainspring 22 is wound up, the pinion 24 and the pinion 2
6 is disengaged, so that the driving force is not transmitted to the other gears forming the first gear portion.

Next, the second gear part is located on both sides of the swinging member 2,
and pinions 51.51 fixed to support shafts 5o, 5o that mesh with teeth 2a carved on the outer periphery of the swinging member 2;
It is formed by a crown gear 52.52 fixed coaxially with the pinion 51.51, and a gear 54 fixed to a support shaft 53 that meshes with one of the crown gears 52.52. The gear 54 meshes with the spur gear 11 fixed to the operating shaft 3, and the crown gear 52.52 meshes with the spur gear 11 fixed to the operating shaft 4.5.
It is meshed with 5.15. As a result, the rotational driving force of the first gear section is transmitted to the second gear section via the swinging member 2, so that the operating shaft 3.4.5 can be rotated in forward and reverse directions, and the operating shaft 4. A rod member 12.12, whose lower end rests against a flat surface 16.16 of .5, can be moved up and down.

In the above, the swing motion device A in the toy is the string wheel 42.
By pulling the string 43 wrapped around the drive shaft 20
When the mainspring 22 is wound up and the string 43 is released, the unwinding force of the mainspring 22 is transmitted to the drive shaft 20, and the spur gear 21 fixed to the drive shaft rotates. The gear also rotates, thereby allowing the swinging member 2 to swing left and right about the support shaft 6.

Since the pinion 51.51 of the gears constituting the second gear portion is engaged with the tooth portion 2a carved on the outer periphery of the swinging member 2, the swinging of the swinging member 2 causes the pinion 51.51. 51 rotates in forward and reverse directions, the other gears forming the second gear portion also rotate in forward and reverse directions. Since the spur gear 11.15.15 provided at the other end of the operating shaft 3.4.5 is meshed with any of the other gears constituting the second gear portion, the operating shaft 3. .4.5 can be rotated forward and backward in the same way. In addition, the flat surface 16.16 of the actuating shaft 4.5 has a rod member 12 loosely fitted into the through holes 3a, 3a of the actuating shaft 3.
．． Since the base end force 3 of 12 is in contact, the operating shaft 4.5
The rod member 12.12 can be repeatedly moved up and down by the forward and reverse rotation of the rod member 12, 12, and can be moved out and out of the upper part of the operating shaft 3.

In the above embodiment, the drive source of the swing motion device A uses the mainspring 22, but is not limited to this. For example, as in another embodiment shown in FIG.
Alternatively, a motor 60 attached to the motor 60 may be used.

In this case, the pinion 6 fixed to the output shaft of Mokuro 0
1 may be meshed with a spur gear 62 fixed to a drive shaft 20 whose one end protrudes outside the surface of the casing 1. In this example, the same reference numerals as in FIGS. 1 to 3 indicate the same parts, and the internal structure is the same, so it is not shown.

Next, FIG. 5 shows the swing motion device A in the toy being
The head 72 is attached to the operating shaft 3 of the swing motion device, the arm portions 73 and 73 are attached to the operating shaft 4.5, and the operating shaft is The rod member 12.12 loosely fitted into the through holes 3a, 3a provided in the opening/closing member 75.75 has its tip covering the front surface of the mouth portion 74.74 during upward movement, as shown in FIG. 3(b). The opening/closing member 75.75 is opened and closed about a support shaft 76.76 by contacting the opening/closing member 75.75. As a result, by operating the swing motion device as described above, the head 72 of the doll 70 can be automatically swung from side to side, and at the same time, the arms 73 and 73 can also be oscillated back and forth. So you can get a doll with interesting behavior. Also,
Since the mouth portions 74.74 can also be made to blink via the opening/closing members 75.75, the realism can be improved. Furthermore, since a slip clutch mechanism S is provided at the attachment portion between the arm portion 73.73 and the body portion 71, as shown in FIG. When an overload is applied, such as when an overload is applied, this mechanism works and only the arm portions 73 and 73 rotate relative to the body portion 71, thereby preventing damage. It is best to use a doll with a height of about 280 mm, a chest width of about 40 mm, and a chest thickness of about 25 mm.
