Description

  The present invention relates to a doll such as an animal and a toy that moves a flower, and more particularly to a swinging toy provided with a device for swinging a swinging portion thereof.

Conventionally, the swinging doll toy as shown in the following Japanese Patent Laid-Open Publication No.
It was a movement that just swung the head back and forth, and it was not interesting. Then, like the doll toy shown in FIG. 6, FIG. 8, FIG. 9 in Patent Document 1, the doll swings in the three-dimensional direction of the left and right, and front and back, thereby making the movement more interesting.
However, the rocking has a smooth constant amplitude, and in order to find fun and change, a person must touch and push the doll to make the rocking regular rocking.

Patent No. 2937287 JP 2004-24494 A

In addition, a method for irregularly swinging the swinging part of the doll in the three-dimensional direction has been developed,
The fun of the movement was improved by the invention technology of the following patent application, and it was possible to make an interesting movement that does not get the viewer bored. That is, there is an unpublished Japanese Patent Application No. 2006-227287 filed on August 24, 2006. However, the problem with this technique is that a pendulum swing device, which is a well-known technology, must be installed behind the doll swing portion, which is limited in design and costly. As a result, the toy is relatively expensive.

  In the electronic circuit of Patent Literature 1, the toy swinging part is continuously excited by the relative electromagnetic force between the swinging part permanent magnet and the fixed part electromagnet excited by intermittent energization. However, even if a pivot bearing is used, the vibration direction change (left / right, front / rear) and amplitude change of the toy rocking part can be made automatically without a manual push even if there is a steady and gradual change. There wasn't.

  Therefore, in the present invention, the driving permanent magnet of the toy swinging portion that is magnetically opposed to the restraining magnet by at least one restraining magnet fixed to the toy fixing portion, and the magnetism of the restraining magnet It takes measures to break the dynamic balance and gravity balance, and to make a sudden change of the operation locus automatically at irregular timing and permanently. Further, by changing the magnetic field strength of the restraining magnet manually or automatically as in claims 2 and 3, the restoring force of the lateral swing due to the relative magnetic force with the drive magnet is changed, and the swing toy It is possible to control the movement of.

  The present invention is such that a pivot bearing is fixed to the upper part of a toy fixing portion, and can freely rotate and swing in a three-dimensional space with the concave bottom surface of the pivot bearing as a rotation center with respect to the concave bottom portion of the pivot bearing. A needle shaft having a needle tip on the upper portion of the center of gravity of the toy rocking portion is placed on the concave bottom surface of the receiving seat, and a driving permanent magnet is fixed around the toy rocking portion fixedly supported by the needle shaft. In addition, an electromagnet for applying a magnetic driving force to the driving permanent magnet is disposed in the toy fixing portion, and the electromagnet is intermittently energized by a known electronic circuit. Further, at least one or more restraining magnets arranged and fixed on the toy fixing part are magnetically opposed to the driving permanent magnets of the toy swinging part. As the toy swinging part swings, the relative movement of the opposing face is forced by a change in the toy swinging part gravity system restoring force and the magnetic restoring force between the magnets. The movement and magnetic restoring force are made to move left and right so that a three-dimensional three-dimensional movement trajectory is synthesized, and the toy swinging part driving permanent magnet is moved away from the center position of the toy fixing part electromagnet. The toy rocking part is excited and accelerated by energizing the electromagnet at the moment when it is set to, and the direction of the driving permanent magnet is automatically changed from the previous rocking trajectory without human touch, or the peripheral speed is accelerated. In this way, it is possible to continue the movement different from mere free vibration.

According to the present invention, the restoring force of gravity and magnetic force that swings in the three-dimensional direction, which is the force that continues to swing the toy, can be transmitted in the three-dimensional direction without any energy loss, and the needle tip of the pivot bearing For example, a toy that moves permanently with a small amount of electric power obtained by the brightness of the room can be produced.
Conventional swinging toys powered by solar cells were swung with a restoring force due to gravity in order to swing in a two-dimensional direction. However, in the present invention, the movement trajectory of the toy rocking portion does not become a simple vibration, the rocking cycle and the rocking direction change irregularly, and it is not a simple reciprocating motion in the past, but the movement direction suddenly changes. You can make complicated and irregular movements that you don't know. Therefore, it is possible to relieve stress by relaxing the person as a swinging doll toy without getting tired of the viewer by the fun. In addition, it is possible to make such a complicated movement much cheaper than making it with other mechanisms (cam mechanism or robot mechanism).
Furthermore, since the swing direction of the three-dimensional swing can be changed without touching the toy swinging portion, there is a mysterious feeling and a more interesting toy can be obtained.

1 and 2 show an embodiment of the present invention, which is a swinging toy of a hollow plastic molded dog doll.
In the figure, the doll fixing part 1 is formed with a dog torso 1b seated from a table 1a, and a receiving seat 3a of a pivot bearing 3 is arranged on the torso center line at the upper part of the torso 1b, and an air-core coil 4 is placed on the front side thereof. The fixed portion frame 1c, which is disposed and fixed to each other, is molded integrally with the body 1b from plastic.

On the other hand, the doll swinging portion 2 has a swinging portion frame 2b in which a needle shaft 3b on which the needle tip is placed is fixed vertically to a receiving seat 3a of the pivot bearing 3, and is integrated with the doll head inside the hollow doll head 2a. Molded with plastic.
A drive magnet 5 is fixed to the front inner surface of the doll head, and is opposed to the air-core coil 4 of the doll fixing portion 1 with a slight gap.
Further, a weight 6 made of iron plate is fixed to a grooved shelf 2c prepared on the back side of the inner surface of the head so that the center of gravity of the entire doll swinging portion 2 is slightly below the needle tip of the needle shaft 3b. .
In the figure, reference numeral 7 denotes a detachment prevention part that prevents the doll head 2 from being detached from the body 1b, and is attached to the swinging part frame 2b by screws 8 in the figure.

On the other hand, a microphone-like bar magnet 10 that is slidably supported in a pipe of a pipe part 11 that is rotatably attached to the upper part of a microphone column 9 established in front of the stand 1a is attached so as to be movable. The magnetic pole is opposed to the driving permanent magnet 5 on the front side of the doll head while maintaining an appropriate magnetic relative position.
In this embodiment, when the air core coil 4 is energized by the electronic circuit of Patent Document 1, the doll swinging portion 2 is accelerated by the electromagnetic action of the drive magnet 5 and the air core coil 4, and the needle tip of the needle shaft 3b of the pivot bearing 3 is moved. Start swinging around the center of rotation.
However, unlike the conventional swinging only in the two-dimensional direction, when the magnetic center position of the drive magnet is eccentric with respect to the center of the air-core coil 4 when energized from the electronic circuit, as shown in FIG. The driving magnet receives a force indicated by f in the figure, and changes its two-dimensional direction swing, and the doll swinging section 2 changes suddenly in the three-dimensional direction.

The swing restoring force in the case of the back and forth (up and down) movement of the doll swinging part 2 has the restoring force of gravity applied to the center of gravity, but when it moves left and right, the restoring force due to gravity disappears, and from the stand 1a The magnetic attractive force between the bar magnet 10 imitating the microphone facing the front of the doll head 2a on the upper side of the established microphone post 9 and the drive magnet 5 of the doll swinging unit 2 becomes the left-right restoring force, and the doll The left and right swinging of the swinging unit 2 is excited.
However, the swinging movement of the doll swinging part 2 changes the swinging period and swinging direction according to the deviation between the swinging part drive magnet 5 and the center of the air-core coil 4 of the fixed part 1 as shown in FIG. In other words, three-dimensional swinging can be performed.

As a means for changing the state of the three-dimensional swing, the claims 2 and 3 of the claims will be described. A rod imitating a microphone so as to slide in the pipe of the pipe part 11 attached to the upper end of the microphone column 9. When the position of the magnet 10 is brought closer to the doll swinging portion 2 as indicated by a two-dotted line in the figure, the restoring force in the left-right direction increases, and the front and rear (up and down) of the doll head as if the doll is singing into the microphone. The probability of direction swing increases, and conversely, when retracted away from the doll swing section, the restoring force in the left and right direction decreases, and the movement of the doll swing section increases in the left and right direction. At this time, the doll fixing section A stopper 2d which protrudes forward from the upper part of the swinging part frame 1c to the piano wire 13 established on the left and right of the frame 1c, and which is disposed between the two piano wires and protrudes forward from the swinging part frame 2b. To piano wire 13 You can bounce around and turn your doll's face again towards the weakly resilient microphone.
The ability to change the manner of movement of the swinging toy according to the preference of the person has the effect of further increasing the enjoyment as a toy.
In the figure, reference numeral 12 denotes a microphone head molded from plastic in terms of design.

In order to change this movement, the bar magnet 1 imitating a microphone is not used manually.
A coil 15 is wound around 0, and when a sound such as music is emitted around the coil, excitation is performed so as to increase the magnetic field of the bar magnet 10, and the doll is only two-dimensionally back and forth (up and down) toward the microphone. Oscillation can be performed, and switching to three-dimensional oscillation can be performed automatically by silencing.
According to the invention of claim 2, there is an effect of increasing the enjoyment and fun of the toy.
However, according to the present invention, the toy swing can be changed by always energizing the restraining magnet in proportion to the volume of the surrounding sound source by using the restraining air core coil 14 in FIG.

This embodiment is a toy that swings the movement of the lion dance neck irregularly in a three-dimensional direction.
As shown in FIGS. 5, 6, and 7, a plastic insulator neck 202 a supported in a three-dimensionally swingable manner by a mortar-shaped pivot receiving seat 203 a is provided on an upper portion of the insulator doll fixing portion 201 b fixed to the base 201 a. Is arranged. The neck 202a of the lever has a needle shaft 203b on which the needle point rides, and is fixed to the concave bottom of the pivot receiving seat 203a. A drive magnet 205 is fixed to the last part of the insulator neck 202a.
