Description

[Detailed description of the invention] (Field of industrial application) The invention is based on a doll's sound emitting mechanism, specifically, a rotating gear is engaged with a claw in a hollow part provided in a hollow body.
The present invention relates to a sound producing mechanism that generates sound by flicking a pawl with a gear when the rotary gear is rotated.

(Prior Art) Dolls that move their mouths, limbs, etc. using power sources such as springs have been proposed and implemented in the past, but in order to make their movements more realistic, it is desirable that they be accompanied by voices. However, many conventional generators use voice synthesis ICs or whistle devices, which have disadvantages such as increased overall size and increased cost.

(Object of the invention) An object of the present invention is to solve the above-mentioned drawbacks and to provide a doll sound producing mechanism that can generate onomatopoeic sounds with a particularly simple structure.

(Means for Achieving the Object) In order to achieve the above object, the doll sound producing mechanism according to the present invention is characterized by having the following requirements.

(a) A thin synthetic resin cavity should be provided inside the body.

(b) Claws are formed on the surface of the cavity.

(c) A rotary gear is provided inside the body portion to cause the hollow portion to resonate by strumming the hollow portion by continuously engaging with a claw in the hollow portion.

(Operations and Effects of the Invention) As described above, according to the present invention, by rotating the rotary gear, the gear intermittently engages with the pawl in the hollow portion, thereby repelling the pawl. This strumming causes the cavity to resonate and generate onomatopoeic sounds. The rotating gear above is a doll's hand,
If it is operationally connected to the motion drive device of the legs, mouth, etc.
Since the movements are accompanied by sounds, the doll's realism can be improved with a simple structure. Moreover, since the motion drive device has a rotating mechanism in most cases, and the cavity can be provided by utilizing a gap in the body, costs can be kept low.

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

In the figure, symbol A indicates a doll. This doll A
The head 2 provided on the upper part of the body part 1 is rotated upward by horizontally rotating the waist part 3 to open the mouth part 5, and at the same time, the sound producing mechanism generates an onomatopoeic sound.

The body part 1 is formed hollow, the front upper part and the central upper part thereof are open, and a head 2 having an upper jaw 2a is provided therein. The lower jaw 2b is the body part 1
It is formed at the top of the front open part of. A shaft part 11 is formed hanging down from the lower part of the head part 2, a projection part 12 is formed in the left and right directions in the middle of the shaft part 11, and a projecting part 13 is formed in the left and right direction at the lower end of the shaft part 11. ing. Further, shaft portions 8, 8 protruding from the proximal ends of arm members 7, 7 are inserted into the through holes 6, 6 formed on both sides of the body portion 1 without being able to come out. , 8 are provided with cam plates 10, 10 having protruding shafts 9, 9 at eccentric positions. The protrusion 12 of the head 2 and the shafts 8, 8 of the arm members 7, 7 are provided coaxially, and the head 2 supports the support shafts 14, 14 protruding from the protrusion 12 on the shaft 8. ,8
It is rotatably supported in a recess (not shown) provided at the end of the shaft. As a result, the head 2 is attached to the support shaft 1.
It can swing back and forth around 4 and 14. Further, a coil spring 15 is wound between the protruding portion 12 and the shaft portion 8, so that the head is always biased in the direction of lowering the head 2.

Next, a thin hollow section 20 made of synthetic resin is formed in the back side inner wall of the body section 1. This cavity 20 is formed in a speaker-shaped disc body 21, and a claw 22 is formed in the center thereof.

The waist part 3 is provided so as to be horizontally rotatable relative to the body part 1, and a cylindrical part 26 is provided on the upper part of the waist part 3 via a clutch mechanism 25. The clutch mechanism 25 has a cylindrical part 27 at the upper part of the waist part 3 that rotates together with the shaft 40, and a cylindrical part 28 at the upper part of the upper part of the cylindrical part 27 that rotates freely with the shaft 40. They are formed into a wave shape and interlock with each other, and are brought into strong contact with each other by a spring 29. As a result, when the waist portion 2 is rotated beyond a predetermined rotation range, only the cylindrical portion 27 rotates idly and the cylindrical portion 26 does not rotate. Cylindrical part 26
Engagement grooves 30 are formed in the vertical direction on both upper sides of the
The protruding shaft 9 of the arm member 7 is engaged with the engagement groove 30. Further, an engagement wall 31 is formed upright at a rear position from the center of the bottom of the cylindrical portion 26, and the engagement wall 31
The projecting portion 13 of the head 1 is arranged so as to be engageable. Furthermore, a gear 32 is provided on the rear outer periphery of the cylindrical portion 26.
is formed, and the gear 32 is connected to the claw 2 of the cavity 20.
2 is engaged.

In the above configuration, when the waist portion 3 is rotated in the horizontal direction with respect to the body portion 1, the cylindrical portion 26 is also rotated, and accordingly, the engagement grooves 30, 30 are moved in the front-rear direction. The protruding shafts 9, 9 are moved in opposite directions, thereby causing the arm members 7, 7 to rotate in opposite directions. At the same time, since the engagement wall 31 rotates in the horizontal direction, its end presses the overhang 13 forward, and the head 2 swings backward about the support shaft 14. As a result, the upper jaw 2a separates from the lower jaw 2b as shown in FIG. 1, and the doll A performs the action of opening its mouth. Furthermore, since the gear 32 continuously engages with the pawl 22 of the cavity 20 due to the horizontal rotation of the cylindrical part 26, the cavity 20 resonates due to vibrations based on this strumming action, and an onomatopoeic sound is generated. In this way, onomatopoeic sounds are generated along with the opening of the mouth and the back and forth movements of the hands, and this has the effect of giving the illusion of a doll's voice, thereby improving the realism of the doll.
