Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a facial expression-changing toy whose face rotates each time the torso of the doll is rotated to express different facial expressions.

(Purpose of the invention) The expression-changing doll according to the invention has the following structural requirements in order to enable the face to rotate by a predetermined angle and express different expressions by rotating the doll's body. It is characterized by having

(a) A fixed shaft that protrudes upward is fixed to the lower body of the doll.

(b) A torso member is rotatably supported on the upper part of the lower body part of the fixed shaft, and the torso member is rotated in one direction of the fixed shaft by a spring mechanism interposed between the torso member and the lower body part. and a ratchet portion is formed on the periphery of the upper end of the bearing portion.

(c) A face member is rotatably supported on the upper part of the body member of the fixed shaft, and has a plurality of face parts with different facial expressions drawn at predetermined intervals on the outer peripheral surface of the face member, and on the lower surface thereof. A ratchet portion that meshes with the ratchet portion of the body member is provided.

(d) An elastic member that presses the face member toward the body member is provided at the upper end of the fixed shaft.

(Example) The expression-changing doll of the present invention will be described below.

FIG. 1 is an overall view of an embodiment of the present invention, FIG. 2 is a sectional view thereof, and FIG. 3 is an exploded sectional view of each component. A fixed part 6 consists of an ivy base 2, a rod-shaped spring 4 whose lower end is fixed on the base 2 and holds a baseball 3 at the upper end, and a lower body part 5 that is integrated with the base 2; A fixed shaft 10 protrudes upward from the upper opening, an inverted cup-shaped trunk 20 rotatably inserted and supported by the fixed shaft 10 and positioned at the upper part of the lower body 5, and the trunk 2.
0, the arms and butt 20a, and the torso 2
A cup-shaped face part 30 rotatably inserted and supported by a fixed shaft 10 that penetrates upward through the face part 30;
A head (hat part) 40 is fixed to the upper end of a fixed shaft 10 that protrudes upward from the opening of the body and is located above the face part 30, and a torso that is housed inside the lower body part 5 and rotates around the fixed shaft 10. A spring mechanism 11 for biasing the parts, and ratchet parts 21 and 31 (fixed shaft 10
(coaxially with) and the face part 3.
0, and a return prevention member 50 inserted and fixed to the fixed shaft 10 between the bearing part 35 and the head 40. It is configured.

The spring mechanism 11 for biasing the torso includes a rotation mechanism 15 and a coil spring 16. The rotation mechanism 15 includes a rotary cylinder 13 rotatably supported on the outer periphery of the fixed shaft 10 between a fan-shaped fixed plate 12 fixed to the inner wall of the lower body part 5 and the bottom surface, and a rotary cylinder 13 rotatably supported on the outer periphery of the fixed shaft 10, and a rotating cylinder 13 at the upper end of the rotary cylinder 13. Consisting of an integrated rotating plate 14 and a rod-shaped connecting protrusion 14a protruding from the upper surface of the outer diameter side of the rotating plate 14, the coil spring 16 has its lower end supported by the bottom surface and its upper end connected to the rotating plate. 14 and is wound around the outer periphery of the rotary cylinder 13 to constantly urge the rotating mechanism 15 in the bat swing direction, that is, in the forward direction (direction A in FIGS. 1 and 4). When the rotation mechanism 15 is pressed and rotated in the return direction (direction B in FIGS. 1 and 4), the spring 16 contracts, and when the pressing force is released, the spring 16 is configured to return vigorously to the bat swing direction A. There is. A cylindrical hole 20b into which the connecting protrusion 14a of the rotary plate 14 fits is formed in the upper part of the inner wall of the body 20, and the connecting protrusion 14a
By fitting into the hole 20b, the rotation mechanism 1
5 and the body 20 are configured to rotate together.

Ratchet parts 21 and 31 forming a rotational power transmission mechanism located at the sliding part between the body part 20 and the face part 30
The direction of the ratchet gear is set so that the face portion 30 can rotate only in the bat swing direction A, and the ratchet portions 21 and 31 are pressed together with a predetermined force by a return prevention portion 50, which will be described later. Since rotation in the return direction B is prohibited, when the rotation mechanism 15 and the body part 20 are rotated in the return direction B against the spring 16, the face part 30 does not rotate in the return direction, but the pressing force is The ratchet portion 21 of the barrel tries to rotate in the bat swing direction A due to the return force of the spring 16 when released.
The face part 30 is configured to be rotated in the bat swing direction A by pressing the ratchet part 31 of the face part. Each ratchet part 21, 3
1 is composed of, for example, four gears so that the face part 30 rotates by one gear (45 degrees) for each swing, and the face part 30 expresses different facial expressions at 45 degree intervals. It is configured so that a different facial expression appears with each swing.

The return prevention part 50 has a hole 51a which is fixedly inserted into the fixed shaft 10 in a non-rotatable manner as shown in FIGS. 5a and 5b.
It consists of a base 51 having a base 51 and a leaf spring 52 fixed to the lower surface of the base 51 to prevent return. The return prevention part 50 is pressed against the bearing part 35, so that
The tip of the leaf spring (in this embodiment, a helical spring) 52 is configured to elastically press into engagement with the ratchet gears 35 (four of which are formed to match the ratchet parts 21 and 31) of the bearing part 35. There is. Similarly to the ratchet parts 21 and 31, the direction of the ratchet gear 35 of the bearing part 35 is set so as to prevent the face part 30 from rotating in the return direction. In addition,
Instead of providing the return prevention part 50, the ratchet parts 21 and 31 may be engaged with each other by the weight of the face part 30 itself to prevent the return.

In the above configuration, the spring 16 that rotates the body 20 having the butt 20a in the return direction B from the state shown in FIG. The bat hits the ball 3 at the tip of the rod-shaped spring 4. When the body portion 20 is rotated in the return direction, the face portion, which is prevented from rotating in the return direction by elastically engaging the ratchet gear 35 of the bearing portion 35 at the tip of the leaf spring 52 of the return prevention portion 50, does not rotate. Therefore, the ratchet part 2 of the torso
1 climbs over the ratchet portion 31 and rotates in the return direction. When the body rotates forward, the gear of the ratchet part 21 meshes with the gear of the ratchet part 31 to rotate it forward. In the above embodiment, the amount of one rotation of the face part 20 is the same as that of the ratchet part 2.
Since it is set to correspond to one gear 1, 31, the facial expressions drawn on the outer circumferential surface of the face are sequentially replaced and brought to the front by one rotation. Since the head 40 is fixed to the fixed shaft 10, it does not rotate.

(Effects of the invention) As described above, according to the expression-changing doll of the invention,
By rotating the doll's body, the face can be rotated by a predetermined angle to express different facial expressions.
