JPH0647508Y2 - Sound response doll - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a doll that moves in response to a user's clap sound or other intentionally generated sound.

[Prior Art and Its Deficiencies] Conventionally, dolls that move in response to a sound made by a person are known. However, since the movable part only makes a monotonous reciprocating motion of a part of the doll, the motion of the doll is a typical mechanical or robotic motion, and the motion mode or the atmosphere represented by it is unnatural. However, there is a drawback in that the emotional bond between the user and the doll is weak, and the feeling of attachment does not occur.

[Technical Problem to be Solved] In consideration of the above points, the present invention responds to the action of the user making a sound such as clapping his hand or making a voice toward the doll, and in response to this, the infant The present invention intends to provide a sound-action doll that dances, walks, and so on in a motion mode similar to, and has a strong attachment feeling.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, a doll has a sound sensor built-in, and a motor that is rotated when a sound of a predetermined volume or more is sensed is provided. The waist, which is twisted through a cam and lever, is freely rotatably fitted to the lower part of the body of the doll body so that the legs can be fixed to the waist at any angle from the standing posture to the crawl posture. It is characterized by being installed.

[Operation] When a sound of a predetermined volume or more is produced by clapping hands or making a voice toward the doll, the sound sensor operates and the motor is rotated. The cam rotates in conjunction with the rotation of the motor, and the lever rotatably attached to the doll body makes a twisting motion. A waist loosely fitted to the body of the doll is connected to this lever, so that the waist moves like a baby's waist. Therefore, depending on whether the leg is in the standing position with respect to the waist, the position of the crawling position, or the intermediate position between them, in the same manner as an infant, a motion such as upright walking, high-high walking, and dancing is performed.

[Embodiment of the Invention] Next, the invention will be described with reference to the drawings.

The doll according to the present invention comprises a doll body 1, a waist 2, and legs 3. The doll body 1 has a head portion 1a, a body portion 1b and an arm portion 1c, and a waist 2 is loosely fitted to the lower end portion of the body portion and rotatably connected to the doll body 1 via a lever described later. There is. Leg 3
Are attached to the left and right sides of the waist 2 and overcome the friction through the shafts provided at the base to rotate to the upright posture as shown in FIG. 1 or the crawl posture as shown in FIG. The angle can be

The body 1b of the doll body 1 is hollow, and an electric drive system for detecting a sound and rotating a motor is provided in the body 1b as shown in FIG.

That is, the sound sensor 4 is provided inside the small hole provided on the chest or the back of the trunk, and the sound sensor 4 is provided with the amplifier circuit 6, the level detection circuit 7, and the one-shot multi-circuit wired on the substrate 5. A waveform shaping circuit 8 such as a vibrator and a drive circuit 9 are sequentially connected. These circuits are provided with a power source 10 such as a dry battery, and each circuit is turned on / off by operating a switch 11 provided on the doll body.

When the switch 11 is in the ON state and a sound S is made by tapping a hand near the body of the doll, the output of the sound sensor 4 is amplified by the amplification circuit 6, and when the amplified output is a certain value or more. The level detection circuit 7 outputs and the output is the waveform shaping circuit 8.
Is converted into a rectangular wave with a constant time width by the drive circuit 9, and the drive circuit 9 rotates the motor 12 based on the rectangular wave.

The motor 12 is attached to a box-shaped frame 13 as shown in FIG. 4 attached to the hollow portion of the body of the doll body 1. As shown in FIG. 6, a reduction gear 16 composed of a crown gear 15 meshed with a pinion 14 fixed to the rotary shaft of the motor and other gears is mounted in the frame 13, A shaft 17 supporting a gear at its end extends to both outer sides of the frame 13, and cams 18a and 18b are fixed to both ends of the shaft, respectively. Each cam has pins 19a, 19b at different positions.

A support shaft 20 is provided at a lower portion of the frame 13 so as to project parallel to the shaft 17 on both sides, and a lever 21 is supported by both ends of the support shaft.

The lever 21 is formed in a substantially U-shape with both side portions 21a and 21b and the base portion 21c, and the support shaft 20 is pierced and supported at a position near the base portion on both side portions.

One end of the support shaft 20 is inserted into a perfect circular hole 22a formed on one side surface of the frame 13, and the other end is inserted into a horizontally elongated hole 22b formed on the other side surface of the frame 13. Further, the lever 21 is provided on both side portions 21 extending parallel to both side surfaces of the frame 13.
Vertically elongated holes 23a and 23b are provided near the ends of a and 21b, and pins 19a and 19b of the cams 18a and 18b are inserted into the elongated holes, respectively. When the cams 18a and 18b are rotated by the motor via the shaft 17 due to the coupling structure of the frame 13, the cams 18a and 18b, the support shaft 20, and the lever 21, the rotation angle of each cam is different from FIG. As shown in FIG. 5c, since the upper part and the lower part of the lever 21 are asynchronously moved to the left and right, the protrusion 24 protruding from the lower end of the lever 21 makes a so-called twisting motion. 5A to 5C, (a) is a left side view of the mechanical drive system, (b) is a right side view of the same, and (c) is a bottom view.

As shown in FIG. 7, the waist 2 is loosely fitted so as to cover the lower part of the body of the doll body 1, and the protrusion 24 is joined to the inner bottom of the waist.

The leg 3 attached to the waist 2 has a shaft 25 that does not come out from the waist at the base.
By rotating around this axis by overcoming friction, it is possible to put the leg in an upright position as shown by the solid line in FIG. 7, and rotate backward as shown by the chain line in FIG. Then, it is possible to maintain the posture when walking high and high.

By accommodating the dry battery 10 in the waist 2 as the power source, the center of gravity of the doll is lowered so that the doll is well-balanced even in the standing posture and does not easily fall.

With the above configuration, when a clapping hand is made near the doll to make a sound or a voice is called to call the doll, that is, when a sound more than the noise normally perceived is emitted, the sound sensor is activated. By working, the motor 12 is rotated for a predetermined time via the drive circuit 9. When the sound is continuously emitted, the motor is rotated for a corresponding time.

Then, the rotation of the motor causes the lever 21 and hence the waist 2 to knead with respect to the doll body 1 via the cams 18a and 18b and the support shaft 20.

Therefore, when the legs 3 are extended to the standing posture as shown in FIG. 1, the doll walks upright, and the motion mode thereof is very similar to the walking motion of an infant or the like.

Further, in the state where the legs 3 are rotated backward as shown in FIG. 2, the doll walks in a crawling manner, and the motion mode thereof is very similar to the high-high walking of an infant.

Both walking actions are similar to walking by moving the hips of humans, apes, and other animals, and walk according to the call of the user, so the thing that shows the loveliness of the action is attachment. I can't help but feel.

The arm 1c may be fixed to the body 1b at a constant angle, or may be attached so that it can rotate freely around the root.

Then, in the case of the upright posture, the hand can be linked to the woofer wheel 26 or the like to push it forward. In this case, if a recess 28 is formed in the handle 27 of the Uwa cart and a hand can be inserted into the recess, the doll's hand can be easily connected without having a complicated structure for the handle to hold. You can

If you remove the woofer 26 in Figure 1 and raise the doll's posture a little more, you can get a good balance and dance, and the appearance is very funny and adorable.

[Effects of the Invention] As described above, in the sound-responsive doll according to the present invention, when the sound sensor operates and the motor is rotated, the waist twists with respect to the doll body via the cam, the support shaft and the lever. However, since the legs are attached to the waist so that the legs can be rotated and fixed at any angle from the upright posture to the crawl posture,
After setting the angle of the legs with respect to the waist, when calling the doll with a sound,
Since the person dances, walks upright, or walks high and high, it can behave in a manner similar to that of a true infant, resulting in a very close emotional connection between the user and the doll, and the conventional sound-responsive behavior. A feeling of attachment that cannot be felt for dolls is created.
