Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an action toy using a magnet that allows a movable body to move within a predetermined range.

[Prior art and its disadvantages] A movable body is moved within a predetermined range, and includes a motor provided below a partition plate forming a plane, a gear rotated by this motor, and a cam rotated by the gear. ,
There is one in which a rotating shaft rotated by an interlocking mechanism such as a lever operated by the cam projects outside from a guide hole provided in the partition plate, and a dancing doll is attached to the tip of the rotating shaft.

However, this type of conventional product only moves in a specified order along a specified trajectory and repeats the same movement.

Therefore, the posture and movement of the movable body are monotonous and smooth, with little variation, and the toy user quickly becomes bored with the toy. Furthermore, even when a plurality of movable bodies are used side by side, they all move in the same way, making them unattractive.

In addition, in conventional products, the user of the toy operates the handle himself to move the assembled magnet, or turns on a switch and continuously rotates the motor to move the assembled magnet. Therefore, the movement of the movable body is automatic and passive, and there is no sense of autonomous active movement, so it is useless.

Furthermore, there are conventional stage toys such as mock microphones, musical instruments, and lighting devices.

However, conventional products are simply static or fixed to the stage, and do not move themselves.

Therefore, even if the puppets perform mock demonstration activities such as singing or playing musical instruments on stage, the stage toys such as microphones, musical instruments, and lighting equipment do not move at all, so they do not match the puppet's movements and the puppet's movements are not exciting. This was reduced by half, giving the impression that the degree of mutual enjoyment given to the caregivers was yet another deficiency.

When a stage toy is provided with a movable part and the movable part is to be given movement using conventional technology, power is mechanically transmitted to the movable part from a motor built into the toy. Therefore, since the power transmission 81 has a complicated structure, it has been difficult to miniaturize the toy.

In addition, the conventional products had to be operated and activated by the toy user himself, so there was no surprise and lacked empathy.

[Technical Problems to be Solved] In view of the above points, the present invention provides a movable body with a variety of motions by magnetically coupling a movable body and a movable body and moving a magnet provided on the movable body. The purpose of the present invention is to provide an action toy using magnets that gives the impression that the movable body is actively exercising freely and autonomously.

[Means for Solving the Problems] To solve the above problems, an action toy according to the present invention includes: (a) a sensor; (b) a motor whose rotation is controlled by ON/OFF of the sensor; and (c) A magnet that moves in conjunction with the rotation of the motor; and (d) a movable body that moves under the action of the magnetic field of the magnet.

[Function] When external conditions such as sound, light, and static electricity change, the sensor turns on and off depending on the magnitude of the change. When the sensor is turned on, the motor rotates, and the magnet moves in conjunction with this, causing the magnetic field of the magnet to rotate or change its polarity.

Therefore, when a movable body enters the magnetic field, the movable body undergoes various movements such as rotation, reversal, turning, meandering, etc. depending on the movement or change of the magnetic field due to the attraction or repulsion of the magnet. .

When the magnet moving means is composed of a sensor that responds to sound, light, radio waves, static electricity, etc., and a motor whose rotation is controlled by turning the sensor ON/OFF, external sounds such as
The magnet is moved in response to the sound of a person, a tape recorder, a radio, etc. talking, singing, music, etc., or in response to flashing external lights, radio waves emitted from the outside, or the approach of a human body. A movable object moves in response to changes in external stimuli such as sound, light, and static electricity.

[Example] Next, embodiments of the invention will be described based on the drawings.

First, an embodiment of the present invention will be described in which an independent movable body moves freely under the action of a varying magnetic field.

The first embodiment shown in FIG. 1 is an example in which the polarity of the magnetic field applied to the movable body A1 is alternately changed by the rotation of the assembled magnet B1.

In the magnet-based action toy according to this embodiment, the assembled magnet B1 has a rotating shaft 1 passing through it, and the rotating shaft is rotatably supported by both bearings 2 in a water-like state. One end of the rotating shaft 1 is directly connected to the rotating shaft of a motor C, which is a magnet moving means.

The motor C is used to rotate the magnet assembly B1 around the horizontal axis, and in order to control the rotation of the motor C, a microphone 3, an amplifier 4, a switching element 5, etc. are used to control the rotation of the motor C, as illustrated in FIG. It has a sound sensor D that applies power 6 to the motor C when it senses and outputs a sound volume above a predetermined level.

These sound sensor D, power supply 6, motor C and assembled magnet B1
is housed in a box 7 with the appearance of a stage.

The box 7 has a partition plate 71 giving the appearance of a stage floor. This partition plate 71 is made of a magnetically permeable material and is provided directly above the magnet set 1 at a distance that the magnetic field of the magnet extends above the partition plate. As the magnet assembly B1 rotates, the polarity of the magnetic flux extending above the partition plate alternates.

The movable body A1 has a child magnet 8 made of a permanent magnet inside. The child magnet 8 has its center of gravity at or near the child magnet due to its own weight or the weight of the material of the movable body, and the child magnet 8 is in a natural state (not affected by a magnetic field).
exists at the lowest position of the movable body A1, the movable body A1 stands up, and the child magnet 8 is in contact with the partition plate 71 or at the closest position.

In the illustrated example, the movable body A1 is composed of a peanut shell, a cocoon shell, or a molded body having a shape similar to these, a hat and objects resembling limbs 9° and 10 are fixed to the outer surface, and a child magnet 8 is provided at the bottom, and in its natural state when placed on the partition plate, it maintains a stable standing posture.

In this state, when music with a desired rhythm is played from a tape recorder or radio near this stage toy, the sound sensor D outputs an output depending on the volume of the music and supplies power to the motor C. rotates the assembled magnet B1 in various patterns that approximately match the rhythm of the music.

For this reason, the magnetic flux direction and polarity of the magnetic field transmitted from the assembled magnet B1 through the partition plate 71 and applied to the movable body A1 change.
Due to the combination of the friction between the child magnet 8 of the movable body A1 and the partition plate 71, the attractive or repulsive force acting between the rotating set magnet B1 and the child magnet 8, and the inertial movement of the movable body A1, The movable body A1 performs various free and humorous actions such as lying down on the partition plate 71, suddenly making a large rotation, and standing up.

If the arm 9 of the movable body A1 is made of an elastic material such as a coil spring, it will move more complicatedly and unexpectedly, making it very enjoyable to watch.

What's more, these movements follow the music, so those who watch the movements of these movable bodies while listening to the music can't help but rejoice.

FIG. 4 shows an expansion of the first embodiment, in which a child magnet 8 is provided in the movable body A2 so that different magnetic poles exist at both ends thereof.

As a result, an interesting action can be performed in which the movable body A2 alternately turns upside down due to the alternating magnetic field applied outward from the partition plate 71 as the assembled magnet B1 rotates.

In the second embodiment shown in FIG. 5, the magnetic field of the assembled magnet B2 is made parallel to the surface of the partition plate 71 by installing the assembled magnet B2 at a position offset from the rotation center of the motor C which is the magnet moving means. It is designed to be rotated and moved.

In addition, the movable body A3 in this case is one having a curved outer surface, for example, one having a comical shape such as a perfectly shaped peanut or cocoon shell, or something similar with a hat and limbs attached. and has a child magnet inside the lower half of its movable body.

When the movable body A3 having such a shape is placed on the top surface of the partition plate 71 and a music tape is played near the movable body A3, the sound sensor D is activated depending on the magnitude of the sound, and the motor is activated accordingly. Since C rotates, the assembled magnet B2 moves along the circumference on a horizontal plane. Movable object A on or in the vicinity of its movement trajectory
3 exists, the child magnet of the movable body receives the magnetic force of the assembled magnet.

The child magnets of the movable body exhibit various movement patterns depending on the positional relationship with respect to the moving locus of the magnetic flux of the assembled magnets. In other words, the child magnets 8 and the magnets of different polarities of the assembled magnet B2 come closest to each other. In this case, if the movable body A has an arm 9 made of a zero-elastic material that is attracted to the assembled magnet B2 and rolls and moves in the same direction as the assembled magnet, the arm contacts the partition plate 71 that is the floor. As a result, the rolling direction and speed change slightly, resulting in unexpected movement patterns.

On the other hand, if the child magnet and the assembled magnet are of the same polarity and come closest to each other, the movable body will simply spin suddenly due to the repulsive force.
The amount of movement is small.

The amount and speed of rotation of the assembled magnet B2 vary depending on the magnitude of external sound. Therefore, depending on the combination of variable factors such as the current position and orientation of the movable body, the position in which it approaches the assembled magnet, and the rotational speed of the assembled magnet, the movable body can move in a wide variety of ways in time with the music, as if It gives the impression that the dancers are free dancing to the music.

In the embodiment shown in FIG. 6, the magnet moving means reciprocates the assembled magnet B3 along an arbitrary curve, for example, a guide groove 111 formed in an S-shape on the guide plate 11. , magnet set B, are moved in the same shape parallel to the surface of the partition plate 71, and the movable body is reciprocated in the same shape along the partition plate surface by the attractive force of the movable body A1 to the child magnet. This is what I did. In this case as well, due to the inertial force generated in the movable body A1 as the magnet assembly B3 moves and stops, the movable body moves back and forth and left and right along the guide hole 111, exhibiting a humorous dance-like movement. ,
When the assembled magnet B3 is rotated and moved, the movable body A1
moves while spinning, making the movement even more interesting.

Incidentally, the S-shaped movement and rotation of the magnet assembly B3 can be carried out by, for example, the S-shaped guide hole 111 of the guide plate 11 shown in FIG.
This is possible by movably inserting the rotary shaft 12 of the motor C to which the assembled magnet B3 is fixed, and by meshing the pinion 13 fixed to the shaft 12 with one side of the curved rack 112 provided on the inner peripheral surface of the guide hole 111. It is.

FIG. 7 is a sectional view showing the positional relationship between the guide plate 11, the motor C, and the assembled magnet B3.

Reference numeral 14 denotes a guide having the same shape as the guide hole 111 for movably guiding the housing of the motor C without rotating it.

11 is an example in which the embodiment of FIG. 6 is further expanded,
A guide hole 111a with a small curvature and a guide hole 111b with a large curvature are provided in the guide plate 11, and assembled magnets are provided in each guide hole so as to be able to move synchronously.The assembled magnet B3a provided in the guide hole 111a with a small curvature is The assembled magnet B is moved without rotating and is provided in the guide hole 111b with a large curvature.
3b is rotated and moved so that the partition plate 7
When two movable bodies A1 and A3 having arms are placed on top of the magnet assembly B, one movable body A1 only moves in plane without rotating on the floor of the partition plate 71. On the other hand, the other movable body A realizes a movement pattern in which it spins and moves almost together with the other movable body A1, and the movement is as if a man and a woman are dancing tamp. can be made to

FIG. 9 shows a collection of the above embodiments and three movable bodies A.
1. This figure shows A2 and A3 dancing in different patterns.

In the above embodiment, a sound sensor was used as a sensor for controlling the rotation of the motor C, but instead of the sound sensor, light, static electricity,
By using sensors that respond to external stimuli such as infrared rays and radio waves, actions can be taken in response to changes in external stimuli.

Furthermore, the partition plate 71 may be flat or may have an inclined surface, as shown in FIG. You can also do it.

Next, an embodiment will be described in which a movable body that does not move freely, that is, a movable body connected to a partition plate, is made to move within a predetermined range.

This embodiment was realized as a stage toy.

FIG. 11 shows an example in which a stage toy is composed of a simulated microphone A disposed on a partition plate 71 serving as the floor of the stage, a simulated lighting fixture A6, and a cymbal A1 as a simulated musical instrument.

First, to explain the detailed configuration of the simulated microphone A, as shown in FIG.
2 is provided.

This motor C2 is connected to the O of the sensor D similar to that in FIG.
Controlled by N/OFF.

A magnet assembly B2 is mounted on the rotating shaft of the motor C2 via a mounting member 5 at a position offset from the center of rotation of the motor.

The lower end of a tubular support member 16 having the appearance of a microphone support is fixed to the partition plate 71, and a rod-shaped interlocking member 17 is passed through the support member and rotatably supported at a fixed position. The interlocking member 17 has a simulated microphone 18 in a portion that projects upward from the support member 16 . One end of the child magnet 8 is fixed to a portion of the interlocking member 17 that protrudes below the partition plate 71.

The attachment position of this child magnet is a position where the magnetic force of the assembled magnet B2, which is moved by the rotation of the motor C, acts on this child magnet.

With this configuration, if you apply any music, voice, or other sound from a radio or chime recorder to or near this stage toy, the sound sensor D will activate if the sound is louder than a certain value. Turn ONt to rotate motor C. In conjunction with this, the assembled magnet (is rotated, and the magnetic field of that magnet also moves along a circle, so that the child magnet 8 is attracted or repelled by the approach of the magnetic field, so that the interlocking member 17 to which it is fixed is In other words, the simulated microphone 18 rotates continuously or intermittently depending on the magnitude of the sound.A magnetic material may be used instead of the child magnet.

Next, the simulated illumination device A6 in FIG. 11 basically has the same configuration as the above-mentioned microphone A, and instead of the microphone 18 at the upper end of the interlocking member 17 of the above-mentioned structure,
The only difference is that a simulated light 19 with a light-like appearance is provided.

Subsequently, as shown in FIG. 13, the cymbal A1 in FIG. 11 is constructed by installing a motor C1 with its rotating shaft horizontally under the partition plate 71, and fixing a set of magnets B1 to the rotating shaft at its center. Then, as in the case of the microphone As, the partition plate 7
A lower disk 20 is formed at the upper end of the supporting member 16 erected in 1, and an upper disk 21 is fixed to a portion of the interlocking member 17 that penetrates the supporting member 16 and projects upward from the supporting member, Furthermore, the child magnet 8 is fixed to the lower end of the interlocking member 17 located below the partition plate 71.

With the above configuration, when the motor C is rotated and the assembled magnet B is rotated in conjunction with this, the relationship between the polarity of the magnetic pole approaching the child magnet 8 of the assembled magnet and the polarity of the lower end of the child magnet is As a result, the child magnet 8 receives an attractive force or a repulsive force, so that the interlocking member 17 moves in the vertical direction, and the upper and lower discs 20 and 21 forming the cymbal also move in synchronization.

In order to reduce costs, the rotation of the motors of the lighting fixture A6 and the cymbal A7 is controlled by the ON/OFF'F of the sensor D of the microphone A.

In the example shown in FIG. 14, a simulated pianist 22 is fixed as an example of a demonstrator on the upper part of the interlocking member 17 that is moved upward in FIG. 13, and a simulated piano 23 is placed on a partition plate in front of the pianist. When the magnet set B1 is rotated by the motor with the pianist's hand placed close to and above the piano keyboard, the interlocking mechanism is caused to protrude upward from the partition plate 71 through the interlocking of the child magnets. Part 1
7 is moved up and down, the pianist 22 moves his body up and down and also moves his hands up and down toward the piano keys, giving the impression that the pianist is playing.

Figure 9 shows microphone A, which is the equipment for each stage mentioned above.
Also shown is an example in which lighting fixture A8 and cymbal A7 are arranged on one simulated stage.

In this way, when various types of simulated instruments with movable parts are arranged and music is played nearby, each instrument rotates, moves up and down, etc. in accordance with the volume of the music, that is, the rhythm.

In the above embodiment, the case where the sensor D is a sound sensor was explained, but if a sensor that turns on and off in response to light, radio waves, static electricity from the human body, or infrared rays is used, when the stage toy is irradiated with illumination light, , when irradiating radio waves,
Alternatively, it can be configured to operate when a person approaches.

As explained above, in this stage toy, the movable body is linked to the rotation of the motor through magnetic coupling between the set magnet and the child magnet provided in the interlocking member, so the configuration of the transmission mechanism is very simple. It is possible to provide a stage toy that is easy to miniaturize, has movable parts that can be automatically activated in response to changes in external stimuli such as sound, light, and static electricity, and is highly empathetic.

[Effects of the Invention] As described above, the action toy using a magnet according to the present invention is provided with a magnet that is moved in conjunction with a motor whose rotation is controlled by ON/OFF of a sensor, and the effect of the magnetic field of the magnet is Since the movable body is equipped with a movable body that moves in response to external stimulation, the movable body moves via the magnet in response to external stimulation, so the movable body can be made to move in a wide variety of ways. It is possible to give the impression that the movable body moves autonomously and actively.
