[Detailed description of the invention] Industrial application field This invention relates to a swinging mechanism for a doll, and more specifically to a mechanism that swings the head in conjunction with the movement of the arms or legs of the doll. .

Conventional technology and its drawbacks Conventionally, when a doll's arms or legs are moved, the doll's head swings in conjunction with the movement.
Publication No. 29908, Publication No. 139285, Publication No. 61-139285, Publication No. 29908, Publication No. 139285, Publication No.
Those described in Japanese Utility Model Publication No. 52-52718 and Japanese Utility Model Publication No. 54-43836 are known.

However, in all of these dolls, the head (head) swings horizontally or vertically by rotating one of the arms or legs, and one doll can swing the head horizontally and vertically. I can't let you. Furthermore, the device disclosed in Japanese Utility Model Publication No. 54-43836 swings the head back and forth or from side to side by rotating the waist and moving up and down. Since the bending part presses on the inner wall surface of the hollow head and deforms it to cause the head to swing, the swinging motion is unnatural and there is a limit to the range in which the head can swing, making the movement less reliable. The problem is that the value is low.

Purpose of this invention In view of the above-mentioned conventional products, this invention was developed in such a way that when a doll makes a walking motion, that is, when it swings its arms back and forth, its head swings back and forth (vertical swing), and when its legs swing back and forth, its head swings back and forth. The object of the present invention is to provide a swinging mechanism that swings from side to side (lateral swing).

Means for Achieving the Objective In order to achieve the above objective, the swinging mechanism according to the present invention has a first shaft provided on the head extending downward, which is inserted into the body through the neck hole so as to be rotatable around a vertical axis, and The left and right shafts are supported swingably with the front and rear necks as fulcrums, and an inverted U-shaped link is fixed to the lower part of the first shaft, and a linking pin is provided at one end of the link, and the left and right shafts are rotatably attached to the torso. A cam is fixed on a rotating shaft that connects the bases of the arms of the body, and the cam is fitted into the link, and a fan-shaped cam is attached to the upper end of a second shaft rotatably supported in the body so as to be rotatable around a vertical axis. A linking ring is fixed, and the link is loosely fitted into the linking ring, between the lower part of the second shaft and the bases of the left and right legs that are attached to the trunk so as to be rotatable around a horizontal axis. , the rotation of the leg around the horizontal axis is
The invention is characterized in that it is provided with a motion converting means for converting the rotation of the shaft into rotation about the vertical axis.

Function: When swinging the arm back and forth, the cam rotates and swings the first shaft back and forth via the link, allowing the head to swing back and forth using the neck as a fulcrum. At this time, since the linking pin swings within the fan-shaped linking ring, the swinging of the first shaft is not controlled by the second shaft.

Further, when the legs are swung back and forth, the second axis is rotated by the motion converting means. At this time, the linking ring applies rotational force to the linking pin, so the first shaft rotates around the vertical axis, causing the head to swing sideways.

Embodiment of this invention Next, an embodiment of this invention will be described based on the drawings.

As shown in FIG. 1, a shaft 3 is provided that projects downward from the center of the recess 2 on the lower surface of the head 1, and a substantially inverted U-shaped link 4 is fixed to the lower end of this shaft 3. A linking pin 5 is provided protruding from the top. Then, the shaft 3 and the link 4 are inserted through the neck hole 8 of the torso 6 so that the link 4 is located in the inner chest cavity, and is inserted so as to be swingable in the front and back direction and rotatable around the vertical axis. be.

Further, in order to enable the head 1 to swing and rotate relative to the neck 7, the upper end of the neck is fitted into the recess 2 of the head with some play.

On the other hand, a hole 13 is formed on the side surface of the body part 6 at the base of which the left and right arms 9 have a small diameter part 10 and a large diameter part 11 for preventing the arm from coming off. The bases of both arms are connected by a rotating shaft 14, a cam 15 is fixed on the rotating shaft, and the cam 15 is fitted into the link 4.

Furthermore, inside the shell 6 is a second shaft 18 rotatably supported by a bearing 16 between the flanges 3a and 3b and by a bearing 17 at the lower end.
A fan-shaped linking ring 19 is provided at the upper end, and the linking portion 5 provided at the lower end of the link 4 is fitted into the linking ring. The second shaft 18 is also provided with convex pieces 20 and 21 at its lower part that protrude in opposite directions.

On the other hand, the roots of the left and right legs 23a and 23b, each having a small diameter part 24 and a large diameter part 25 for preventing slippage, are fitted into the hole 22 provided on the side surface of the main part of the body 6 so as to be rotatable at the small diameter part. be. Large diameter portion 2 of one leg 23a
5a is formed with a notch groove 26 that opens above the leg and serves as an actuating part, and when the leg 23 is attached to the body 6, the convex piece 20 of the shaft 18 is inserted into the notch groove 26.
are fitted with a slight play.

The large diameter portion 25b of the other leg 23b is formed into a substantially semicircular shape, and has an abutment surface 27 facing above the leg to serve as an actuating portion, and the leg is attached to the other hole 22 of the body 6 In this case, another convex piece 21 closely corresponds to the contact surface 27 at a position slightly shifted forward or backward from above the center of the small diameter portion 24 .

The first shaft 3, the second shaft 18, the arm 9 and the leg 2
3a, 23b, the body 6 is divided into two front and rear members 6a, 6b having necks 7a, 7b, and after interposing the shaft 3 between the two members, both members 6a, 6b are assembled. A flange 18 provided at the intermediate portion of the shaft 18 with a bearing 16 protruding from the opposing surface of the intermediate portion of the shaft 18.
a, 18b, and the lower end of the shaft 18 is rotatably received by a bearing 17 provided at the inner bottom of the body members 6a, 6b.

With such a configuration, when the arm 9 is rotated back and forth around the base, the rotating shaft 14 rotates in conjunction with it, and the cam 15 pushes the inner surface of the link 4 back and forth, so that the first shaft 3 swings back and forth within the neck 7, the convex spherical surface of the shaft base slides against the upper end surface of the neck 7, and eventually the head 1 swings vertically. in this case,
The linking ring 19 of the second shaft 18 is formed in a fan shape,
Since the linking pin 5 only moves back and forth within its linking ring and no force is applied to it, the legs 23a, 23b
The head can be vertically oscillated regardless of the horizontal oscillation caused by the shaft 18.

Further, when the leg 23a is rotated back and forth around the base, the actuating portion 25a rotates in conjunction with it, and therefore applies rotational force to the convex piece 20, so that the second shaft 1
8 rotates about its axis and rotates the first shaft 3 via the linking pin 5. Therefore, head 1 swings to the side.

Furthermore, when the other leg 23b is rotated back and forth, the contact surface 27 of the other actuating portion 25b applies a force in the back and forth direction to the other convex piece 21, so that the shaft 18 similarly rotates and is applied horizontally to the head 1. make him shake his head. That is, leg 2
When either of 3a and 23b is rotated back and forth, the second shaft 18 is rotated, and the link ring 19 rotates the first shaft 18.
Since the linking pin 5 of the shaft 3 is swung horizontally, the shaft 3 is rotated about the vertical axis. Therefore, head 1 swings to the side.

Effects of this invention As described above, according to this invention, it is possible to provide a doll that shakes its head vertically when its arms are swung back and forth, and shakes its head sideways when its legs are swung back and forth. And since the movement of the arms and legs and the swing of the head are linked,
The doll can move its head according to the intention of the person holding it. For example, the doll can walk and shake its head at the same time, giving the impression that the doll has life and a sense of dynamism that is not found in conventional products. Give to the caretaker.
