Description

  The present invention relates to an action toy, and more particularly to an action toy that swings the upper body in response to sound while asleep.

  Conventionally, as a toy that falls asleep, a doll that expresses a state of entering a sleep state by closing a bag has been proposed (for example, Patent Document 1).

The doll is provided so that the eyeball can be swung freely, and a position sensor for detecting whether the doll body is in a vertical state or a horizontal state and a sound sensor for detecting sound are provided. When the sound sensor detects a sound like a lullaby laying down a doll, it starts blinking, and when the sound continues for a predetermined time, it closes the eyelid and puts it to sleep.
Japanese Utility Model Publication No. 5-35190

  The problem to be solved by the present invention is that the above-mentioned doll expresses the sleep state only with eyes, and does not express the whole body, but its expressive power has a limit.

  An object of the present invention is to solve the above-mentioned problems, and to provide an operation toy that can express a dozing state with the whole body and give a healing heart to what is seen.

In order to solve the above-mentioned problems, an action toy according to the present invention has the following requirements.
(B) The moving toy has a shape such as an animal or a human being. (B) The moving toy has a swing mechanism that swings the upper body in the vertical direction, a sensor that detects sound, and a detection result of the sensor. And (c) the control unit operates the swing mechanism so that the upper body tilts forward in the initial state. (2) the control unit includes: When the sensor detects sound, the swing mechanism is activated and the upper body is raised and swung up and down (e) When the sensor does not detect sound, the control unit Activating the moving mechanism to return the upper body to the initial state

  The controller determines the level of sound detected by the sensor, controls the amount of rising of the upper body based on the determined level of sound, and expresses the response to the loudness by the amount of rising. Is preferred.

  Further, it is preferable that the control unit controls the swing mechanism so that the swing amount and swing interval time of the upper body change randomly, and performs an operation such as a snooze.

  According to the first aspect of the invention, unlike a toy that expresses a sleeping state or awakened state by simply closing or opening its eyes, it can express a dozing state by its upper body movement. An operation toy that can heal your heart can be provided.

  According to the invention of claim 2, the amount of rising of the upper body is changed between a loud sound and a small sound. You can wake up for a moment when you detect a small sound, but you can wake up for a moment, but you can create a state of falling asleep immediately, and you can reproduce a state that is similar to an actual dozing state.

  According to the invention of claim 3, since the swing amount of the upper body and the swing interval time change randomly, the amount of motion and the motion stop time at the time of operation are not irregular and uniform motion, so While being able to express a state of falling asleep, the viewer's heart can be healed.

  The action toy has a shape in which an animal or a child sits, and the action toy is a swing mechanism that swings the upper body in the vertical direction, a sensor that detects sound, and a detection result of the sensor. A control unit that controls the operation of the swinging mechanism. The control unit operates the swinging mechanism so that the upper body tilts forward in the initial state, and when the sensor detects sound, the control unit If the sensor does not detect sound when the upper body is raised and raised, and the sensor does not detect sound, the control unit operates the swing mechanism to return the upper body to the initial state. The operation of the swing mechanism was controlled.

  FIG. 1 shows an example of an action toy according to the present invention, which is composed of a stuffed toy formed in the shape of a small bear sitting with both hands holding a pillow. A swing mechanism A that swings 2 up and down, a sensor 5 that detects sound, a control unit 6 that controls the swing mechanism A when the sensor 5 detects sound, and a battery (not shown) are arranged. Has been.

  The moving toy is not limited to animals, and may be formed to imitate a sitting person (particularly a child).

  As shown in FIG. 2, the swing mechanism A includes a motor 9 and an arm member 12 that uses the motor 9 as a driving force and rotates up and down via a plurality of gear groups 11. Is rotated forward and backward, the first reduction gear 15 meshed with the pinion 14 fixed to the rotating shaft 13 of the motor 9, the second reduction gear 16 meshed with the small gear of the first reduction gear 15, and the second reduction gear The drive gear 17 meshed with the small gear of the gear 16 rotates while switching the direction of rotation, and the arm member 12 screwed to the lever 19 fixed to one end 18 a of the shaft 18 of the drive gear 17 is connected to the motor 9. It rotates in the vertical direction by reverse rotation.

  The distal end portion 12a of the arm member 12 is formed so as to be positioned in the head of the stuffed toy, and the upper body including the head swings in the vertical direction by the vertical rotation of the arm member 12. .

  An engagement lever 20 is fixed to the other end 18 b of the shaft 18 of the drive gear 17. When the engaging lever 20 is engaged with limit switches 25 and 26 arranged on the outer surface of the right frame 21 and the arm member 12 is in a substantially vertical state, as shown in FIG. When the limit switch 25 is turned on and the arm member 12 becomes almost horizontal, the second limit switch 26 is turned on as shown in FIG.

  The two limit switches 25 and 26 restrict the amount of rotation of the arm member 12 so that the arm member 12 does not rotate excessively, and allow the state of the arm member 12 to be recognized. When the switch 26 is turned on, the control unit 6 to be described later stops the operation of the motor 9 and can recognize whether the arm member 12 is in the vertical state or the horizontal state.

  FIG. 4 shows a block diagram of a moving toy. The output of a condenser microphone (hereinafter referred to as a microphone), which is a sensor 5 for detecting sound, is input to two microphone amplifier circuits 30 and 31, and one microphone amplifier circuit 30 is When a loud sound is detected, the detection signal D1 is input to the control unit 6, and when the other microphone amplifier circuit 31 detects a small sound, the detection signal D2 is input to the control unit 6. When the microphone 5 picks up a loud sound, the two microphone amplifier circuits 30 and 31 input the detection signals D1 and D2 to the control unit 6, but the control unit 6 recognizes D1 with priority.

  The control unit 6 may be composed of a microcomputer having a memory 7 in which a control program is stored. The control program randomly sets a rotation direction, a rotation amount, and a stop time of the motor 9 (random time generation). Routine) 8 is provided.

  When the power switch 32 is turned on, the control program rotates the motor 9 in one direction (hereinafter referred to as reverse rotation) until the second limit switch (hereinafter referred to as lower limit switch) 26 is turned on, thereby causing the arm member 12 to rotate. Rotate downward, swing the upper body down and put it in a dozing state, and when it makes a loud noise in that state, the motor 9 is continuously moved in the other direction (hereinafter referred to as forward rotation). The first limit switch (hereinafter referred to as the upper limit switch) 25 is continuously rotated until the arm member 12 is rotated until the first limit switch 25 is turned on. After that, the direction of rotation, amount of rotation, and stop time are controlled randomly according to the random control program, and finally if there is no sound Is programmed to be dozing state is the initial state.

  When the control unit 6 controls the operation of the motor 9 when the forward rotation signal D1 and the reverse rotation signal D2 are input to the motor drive circuit 10, the motor drive is performed for the time (randomly set) during which the control signal is output. The circuit 10 rotates the motor 9 forward or backward.

  Next, the action | operation aspect of the operation | movement toy of the said structure is demonstrated based on the flowchart figure of FIG.

  When the power switch 32 is turned on, the control unit 6 rotates the motor 9 randomly forward and backward until the lower limit switch 26 is turned on, and stops the motor 9 when the lower limit switch 26 is turned on. In this state, the arm member 12 is in a substantially horizontal state, so that the moving toy holds the pillow and enters a doze state (initial state) as shown in FIG. 6 (step ST1).

  The dozing state continues until the microphone 5 detects a sound (step ST2), and when the sound is detected, the control unit 6 determines the loudness (step ST3). If there is D1 in the detection signal, it is determined that the sound is loud, and the process proceeds to step ST4 where the motor 9 is continuously rotated forward until the upper limit switch 25 is turned on (step ST5), and the arm member 12 is brought to the vertical state. Rotate to raise the upper body at once and be surprised to wake up from sleep (see FIGS. 1 and 7A).

  In step ST3, if the detection signal is only D2, it is determined that the sound is small, and the process proceeds to step ST6 where the motor 9 is rotated slightly forward (step ST6), and the upper body is raised slightly in response to the sound. The state is set (see FIG. 7B).

  After that, in step ST7, the motor 9 approaches a doze state while randomly controlling the forward / reverse rotation, rotation amount, and stop time of the motor 9, but if the microphone picks up sound on the way (step ST8), the process returns to step ST3 and the sound is When the magnitude is determined, the motor 9 is controlled in accordance with the volume of the sound, and the arm member 12 is rotated downward until the lower limit switch 26 is turned on without detecting the sound (step ST9), a step is performed. The process proceeds to ST10, the rotation of the motor 9 is stopped and a dozing state is entered, and the dozing state continues until returning to step ST2 and the microphone again detects a sound (see FIGS. 6 and 7C).

  As described above, according to the operation toy of the present invention, the dozing state can be expressed by the movement of the body, and the heart of the viewer is healed, which cannot be obtained by the conventional toy that expresses the sleep only by opening and closing the heel. A moving toy can be realized.
