Detailed Description of the Invention [Industrial applications]

The present invention relates to a movable figure that bends a part of its outer shape by sensing an external stimulus such as light or sound.

[Problems to be Solved by the Invention]

The applicant of the present invention has an appearance such as a can and a bottle of soft drink, and is used as a stationary upholstery in a quiet place. For example, when a person talks to it, We provided a movable figurine whose outer shape was changed by clapping or playing music. In the movable figure according to the previous proposal, the switching element is turned on when the sound sensor that has the microphone as a component catches the external sound, and the power is supplied to the motor to rotate, and the rotational motion shakes the rocking member. It is moved so that its outer shape changes. However, the movable figure according to the above-mentioned proposal is disliked because it is swinging in the left-right direction and is not interesting enough. Therefore, in view of the above problems, it is an object of the present invention to provide a movable figure whose outer shape is changed in a complicated manner.

[Means for Solving the Problems]

The movable figure according to the present invention, in order to achieve the above object,
A bottom member having a drive unit equipped with a motor, a sensor for turning on a switching element by detecting an external stimulus such as sound or light, and rotatingly driving the motor, and a rotation output of the drive unit are input to move the sensor up and down. A gear mechanism that outputs a rotation to two rotary output shafts that are spaced apart from each other, a drive member that is eccentrically provided on each of the two rotary output shafts, and is rotatably supported by one of the drive members. At the same time, an interlocking member movably linked to the other drive member in the longitudinal direction,
An outer skin member made of a soft material is provided between the upper end of the interlocking member and the bottom member, and covers the gear mechanism and the interlocking member. The interlocking member is rotatably supported by the lower drive member through an opening, and is held by the upper drive member through an elongated hole. Further, it is characterized in that the upper driving member has a higher rotational speed than the lower driving member.

[Action]

In the above configuration, when the sensor catches an external stimulus such as sound or light, the motor is rotationally driven and the two rotary output shafts are rotated via the gear mechanism. The interlocking member is pivotally supported by a drive member provided on one rotation output shaft to move up and down, and is swung in the left-right direction by a drive member provided on the other rotation output shaft. The outer cover member is deformed in accordance with the vertical and horizontal movements of the interlocking member. Further, when the rotation speed of the upper drive member is higher than that of the lower drive member, the interlocking member swings left and right a plurality of times while reciprocating up and down once.

【Example】

Hereinafter, a movable figure according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the movable figure a according to the present embodiment has a commercially available soft drink water bottle shape. The bottom member 1 has an outer shape of the lower portion of the bottle, and a storage portion 2 having an opening / closing lid 2a is provided at the center of the bottom surface thereof, and the dry battery 3 is exchangeably stored therein. Further, a concave portion 4 is formed in a part of the bottom surface, and an operation lever 5a of the main switch 5 mounted inside the bottom member 1 is provided. Inside the bottom member 1, in addition to the main switch 5, a microphone 6 as a sensor for catching external sound is provided.
And a drive unit 7 with a built-in motor
Is provided. A gear box 8 is provided on the drive unit 7,
A gear mechanism composed of a combination of a large number of spur gears is attached to the gear box 8, and a drive gear 7a of a drive unit 7 is meshed with an input gear 8a of the gear mechanism. Two output shafts 9a, 9b, which are rotationally driven by the input gear 8a, project from the gearbox 8 with a space in the vertical direction, and the discs 10a, 10b are fixed to these rotary output shafts 9a, 9b. ing. Each of the discs 10a, 10b has a drive member 11a, 11b at an eccentric position.
Is provided, and an inverted L-shaped interlocking member 12 is attached thereto. That is, the opening 13 of the interlocking member 12 is rotatably supported by the driving member 11a located below, and the elongated hole 14 provided in the axial direction of the interlocking member 12 is located above the driving member 11b. Held in. Therefore, as shown in FIG. 2, when the discs 10a and 10b rotate in the directions of arrows a and b, the interlocking member 12 makes a complicated movement in the vertical and horizontal directions as shown by the arrow c.
In this case, if the gear ratio of the gearbox 8 is different,
For example, if the gear ratio is configured such that the disc 10a makes four revolutions for one revolution, the movement of the interlocking member 12 becomes more complicated. An upper member 15 having the outer shape of the upper portion of the bottle is fixed to the upper portion of the interlocking member 12. An outer skin member 16 made of a soft plastic sheet is provided between the upper member 15 and the bottom member 1 so as to enclose the gear box 8 and the interlocking member 12. In the figure, reference numeral 20 is an electric circuit board for controlling and driving the drive unit 7, and its electric configuration is shown in FIG. That is, in the figure, 6 is the above-mentioned microphone, 21 is a switching element which amplifies the output of the microphone 6 by an amplifier 21 'and is turned on by the amplified output, 22 is the main switch 5 and 23 is the aforementioned switch. The dry batteries 3 and M are motors built in the drive unit 7. Therefore, when the main switch 5 is ON and the microphone 6 catches the external sound, the switching element 21 is turned ON, and the motor M is supplied with power from the dry battery 23 to be rotationally driven. In FIG. 4, the motor M rotates, which causes each disc 10a,
It shows the movement of the movable figure when 10b rotates.
That is, the interlocking member 12 is rotated by the respective disks 10a and 10b,
As described above with reference to FIG. 2, since the complicated movement as shown by the arrow C is performed, the upper member 15 and the outer skin member are
The 16 swings to the left and right, and its movement is gentle and slow, and there is a small reciprocating movement, which makes the movement very interesting. In the above-described embodiment, the interlocking member 12 is rotatably supported by the lower drive member 11a and the upper drive member 1a.
It is held in 1b, but it can be reversed. That is, the upper drive member 11b may rotatably support the interlocking member 12, and the lower drive member 11a may hold it. Further, the rotation directions of the disks 10a and 10b may be reversed, and the rotation ratio of the disks may be arbitrary. However, the larger the rotation ratio, the more complicated the movement of the interlocking member 12 is, which is preferable. Further, after once catching the sound and starting the flexion movement, when the sound disappears, an attitude sensor should be provided in parallel with the switching element 21 so that the rotation of the motor is maintained until it returns to the upright attitude. You may

【The invention's effect】

The movable figure according to the present invention outputs the rotation of the drive unit to two rotation output shafts which are vertically separated, and axially supports the interlocking member with a drive member eccentrically provided on one rotation output shaft, Since the interlocking member is held by the drive member eccentrically provided on the other rotation output shaft, the movement of the interlocking member can be varied. Therefore, it is possible to make an interesting change in the outer shape of the movable figure. Further, when the rotation ratio of the output shaft is increased, the movement of the interlocking member is more varied, and the change in the outer shape of the movable figure can be made more interesting.
