[Detailed Description of the Invention] (Industrial Application Field) In this invention, a member supporting a plurality of heads rotates in conjunction with the rotation of the arm, and the head located on the torso is rotated. This invention relates to a face-changing doll toy that can be transformed into a different head.

(Prior art and its problems) As a conventional doll toy with a face changing function, for example, a single head rotatably supported on the shoulders of the torso is disposed, and the outer circumferential surface of the head is A plurality of faces are drawn on the top at predetermined intervals, and by rotating the head in conjunction with predetermined movements of the torso, arms, etc., the face in front of the torso changes. There is something.

However, such conventional doll toys only change the face located in front of the torso by rotating multiple faces drawn on the exposed head, which may cause unexpected movements. It lacked the sense of surprise based on changes and changes, and was easily boring.

(Technical issues with the invention) This invention was created in view of the above circumstances, and it is possible to create an unexpected effect by making the head, which is completely hidden, appear outside based on unexpected movements. The purpose is to propose a face-changing doll toy that is full of fun.

(Means for Solving the Problem) In order to solve the above technical problem, the face-changing doll toy according to this invention is characterized by having the following requirements.

(a) It comprises a trunk, a rotating shaft supported on both sides of the inside of the trunk and having two heads, and an arm rotatably supported at another position on the trunk.

(b) The rotational axis of the head and the rotational axis of the arm are linked via a gear mechanism that can mesh only when rotated in one direction.

(d) The chest and back of the torso are configured to be able to be opened and closed in the front-back direction to allow rotation of the head attached to the head support member.

(Operations and Effects of the Invention) As described above, according to the face-changing doll toy according to the invention, by rotating the arm, the number of rotations (rotation angle) corresponding to the gear ratio of the main gear mechanism,
You can rotate the head to make different heads appear. At this time, the chest and back that make up the torso open and close, making it possible to realize unexpected movements as a whole. Further, since the head is detachable from the head support member, by replacing the head, the player can enjoy playing with a head with a different facial expression.

(Example) Hereinafter, the face-changing doll toy of the present invention will be described in detail.

Fig. 1 is an overall perspective view showing the external appearance of an embodiment of the present invention, Fig. 2 is a side sectional view, Fig. 3 is a front sectional view, and Fig. 4 is an explanatory diagram of the connected state of the arms and legs. ,
FIG. 5 is an exploded explanatory diagram.

This face-changing doll toy 1 includes a body 2, arms 3 rotatably supported by both shoulders of the body 2, legs 4, and a head 5 supported on the shoulders of the body. has.

As shown in FIG. 2, the torso 2 consists of a lower abdomen and a side part of the body, and includes a fixed part 7 having a continuous opening 8 from the front to the back, and a pivot point at the lower front edge of the opening 8 of the fixed part. It consists of a movable chest 10 which is pivotally supported to be freely openable and closable in the front-back direction by a movable chest part 10 that is pivotably supported in the front-back direction by a pivot part 8b at the lower edge of the back of the opening 8, Chest 10,
The back portion 11 is always urged in the closing direction by a spring 12. As will be described later, the fixing portion 7 is configured to be divided into two parts: a front side fixing piece and a back side fixing piece. Movable chest 10 and movable back 11
is configured so that when the head 5 rotates and is replaced, the inner surface is pressed by the head and opens.

The head 5 consists of a first head 5a and a second head 5b having different faces, and each of the heads 5a, 5b rotates around a rotating shaft 17 by a bearing 15 on the inner wall of the fixed part 7. The head support member 16 is removably attached to each attachment/detachment portion 18 at both axial ends of the freely supported head support member 16 . The attachment/detachment portion 18 is configured to be elastically fitted into a fitting recess formed on the bottom surface of each head. A driven gear 19 is fixed to the tip of one rotating shaft 17 .

The arm part 3 has a locking part 20a at the tip of the connecting piece 20, which is rotatably supported by the support hole 7a of the fixed part 7.
It has a fitting recess into which it is fitted (see Fig. 4). A main drive gear mechanism 21 is disposed on the other end (inner end) side of one of the connecting pieces 20 . That is, as shown in FIGS. 3 and 5, this main drive gear mechanism 21 includes a first ratchet gear piece 22 integrated with the other end of the connecting piece 20, and a first ratchet gear piece 22 that meshes with the first ratchet gear piece 22. 2 ratchet gear piece 23
and a main drive gear 24 having a second ratchet gear piece 2 coaxially and integrally therewith, and passing through their centers in the axial direction to connect both members 22, 24, 23 so as to be relatively rotatable and movable in the axial direction. A core material 25,
It has a spring 26 that constantly presses the main drive gear 24 (including the ratchet gear 23) toward the connecting piece 20 (first ratchet gear piece 22), and a spring stopper 27 that projects from the inner wall of the fixing part 7 and supports the core member 25. The main gear 24 is always in mesh with the driven gear 19 of the head support member 16.

As shown in FIG. 5, the leg portion 4 is connected to the body portion 2 by a connecting piece 30 similarly to the arm portion.

The connection structure between the fixing part 7 and the chest 10 constituting the torso is shown in FIG. Note that the fixing piece 7b shown in FIG. 5 is on the front side, and is configured in two parts with the fixing piece on the back side (not shown), and there is no structural difference from the fixing piece on the back side.
Only the front side fixing part 7b will be explained. That is,
The fixing piece 7b has a bearing recess 31 and a fixing member fitting recess 32 continuous with the bearing recess 31 at the lower part of a pair of opposing inner walls 8a of the opening 8.
1 has a shaft 33 protruding from both ends of the pivot member 33.
a is rotatably supported, and the pivot member 3
After installing 3, insert the H-shaped fixing member 3 into the fitting recess 32.
By fitting both ends of the bearing pivot member 34, the bearing pivot member 34 is prevented from falling off. The protruding piece 10a at the lower end of the chest 10 is fitted into the attachment hole 33b formed on the upper surface of the pivot member 33. The chest 10 is rotatable integrally with the pivot member 33. An opening 10b for holding the neck of the head is formed in the upper end piece of the chest 10.

The pivot structure of the chest 10 is similarly applied to the back 11.

In the above configuration, when the arm 3 on the side equipped with the main drive gear mechanism 21 is rotated in the direction in which the ratchet gears mesh, the ratchet gears 22 and 23 mesh with each other, so that the rotational force of the arm 3 causes the main drive gear 24 to rotate. is transmitted to the driven gear 19 via the head support member 1
6 and the head 5 are rotated. Since the inner surfaces of the chest 10 and back 11 are pressed by the rotation of the head 5, the chest 10 and back 11 open outward against the spring 12, and the head 5b, which was located inside the torso, is moved upward. While the head 5a, which had been exposed to the outside, returns to the inside of the body. When the pressing force from the head is removed, the force of the spring 12 causes the chest 10 and back 11 to return to their original closed positions.

When the arm portion 3 is rotated in the opposite direction (the direction in which the ratchet gears are disengaged), the ratchet gears 22, 2
3 are disengaged from each other, the rotational force of the arms is not transmitted to the main drive gear 24, and therefore the head support member 16 does not rotate. At this time, the main drive gear 24 and the ratchet gear 23 move inward in the axial direction while pressing the spring 26 along the core member 25.

Note that by changing the gear ratio between the main drive gear 24 and the driven gear 19, the number of rotations of the head relative to the rotation angle of the arm 3 can be set as desired.

As described above, by rotating the arm, the head is rotated by the number of rotations (rotation angle) corresponding to the gear ratio between the main gear and the driven gear, and a head with a different face appears. be able to. At this time, the chest and back that make up the torso open and close, making it possible to realize unexpected movements as a whole. Further, since the head is detachable from the head support member, by replacing the head, the player can enjoy playing with a head with a different facial expression.
