Description

  The present invention relates to a motion state maintaining apparatus capable of reducing the resistance received by a moving object in a motion state when power is applied and maintaining the motion state of the object for a long time.

  It is desirable from the viewpoint of saving energy resources that a moving object that has obtained a driving force by means of electrical energy or the like is maintained in a moving state for a long time without receiving resistance as much as possible and without attenuating the speed of movement. From this point of view, the present inventor has studied an apparatus using a magnetic force generated by a magnet, and an example of the technique is described in Patent Document 1, for example.

JP 2003-17312 A

  However, this device also has some problems. First of all, an attraction area and a repulsion area are provided by a torsion magnet, but if the boundary area is formed long with respect to the moving direction of the moving body, the presence of this boundary area ignores the moving object. An impossible resistance force is generated, and the moving body is decelerated by this boundary region. Next, since the attracting force and repulsive force from the magnet also work in the direction perpendicular to the moving direction of the moving object, the trajectory of the moving object tends to become unstable.

  As in the above-described Patent Document 1, in an apparatus configured by arranging magnets, the magnetic poles of the magnets have the action of accelerating and decelerating the moving object having magnetism by the action of repulsion and attraction. It was extremely difficult to accelerate a moving object by acting only one of them.

In order to continuously accelerate a moving object, it is necessary that the moving direction of the moving object and the magnetic field lines emitted from the magnet coincide with each other, and for this purpose, the moving object moves along the magnetic field lines generated from the magnet. It is necessary to arrange the magnets so that they can proceed.
From this point of view, the present inventor makes it easy for the moving object to move along the magnetic force lines from the magnetic poles by using the nets made of the magnetic material and dispersing the magnetic force lines from the magnetic poles of the magnets by the nets. I have found that.

  The present invention uses a different means to arrange the magnet so that the moving object can travel along the magnetic lines of force generated from the magnet, and suppresses the moving object from decelerating, thereby controlling the moving state of the moving object. An object of the present invention is to provide an apparatus for maintaining an exercise state that can be sustained effectively.

  In order to solve the above-described problems, the motion state maintaining device unit of the present invention has a holding body made of a magnetic material disposed so as to face both magnetic poles of the main magnet with a gap therebetween, and the holding body is the main body A motion state maintaining device unit that holds a secondary magnet on the opposite side of the magnet, and of the two magnetic poles of the secondary magnet, the magnetic pole far from the magnetic pole of the primary magnet is the magnetic pole of the primary magnet. A magnetic pole having different magnetism and closer to the magnetic pole of the main magnet has the same magnetism as the magnetic pole of the main magnet.

  The lines of magnetic force that generate the repulsive force from the magnetic poles of the main magnet are blocked or confined by the holder, so that the lines of magnetic force acting directly on the moving object from the magnetic poles of the main magnet are significantly reduced, and the moving object moves easily. The state maintenance device unit can be approached, and thereafter it is accelerated and travels along the magnetic field lines generated by the main magnet. Therefore, the moving object can maintain its moving state.

In this invention, it can be set as the structure where the protrusion is provided in the position where the said holding body opposes the magnetic pole of the said main magnet, and the magnetic pole of the said main magnet and the said protrusion are contacting.
When the protrusion is formed, it is possible to magnetize the holding body by contact with the main magnet, which facilitates confinement of the magnetic lines of force from the main magnet, and the area of the contact portion is very small. Can keep.

In this invention, it can be set as the structure where the recessed part is provided in the position of the magnetic pole of the said main magnet, and the bottom face of the said recessed part and the said protrusion are contacting.
If a recess is provided at the position of the magnetic pole, the degree of freedom of the contact angle can be obtained when the protrusion is brought into contact with the inside of the recess. Therefore, the degree of freedom of the contact angle can be used to match the motion trajectory of the moving object. The arrangement state of the state maintaining device unit can be selected as appropriate.

In the present invention, a core material made of a magnetic material is inserted so as to penetrate both poles of the main magnet, and the tip of the core material is in contact with the holding body or the sub magnet. it can.
When the core material is used, the motion state maintaining device unit can be integrated by a simple method, which is convenient when the motion state maintaining device unit is fixed to a fixed plate or the like.

The motion state maintaining device of the present invention is formed by continuously arranging the motion state maintaining device units described above.
By continuously arranging the above-described motion state maintaining device units, it is possible to achieve motion state maintenance according to the motion path and motion form of the moving object.

  ADVANTAGE OF THE INVENTION According to this invention, the movement state maintenance apparatus which can maintain the movement state of a moving object effectively can be implement | achieved.

It is a figure which shows the structure of the exercise state maintenance apparatus unit which concerns on 1st Embodiment of this invention. It is a figure which shows the structure of the exercise state maintenance apparatus unit which concerns on 2nd Embodiment of this invention. It is a figure which shows the structure of the exercise state maintenance apparatus unit which concerns on 3rd Embodiment of this invention. It is a figure which shows the structure of the exercise state maintenance apparatus unit which concerns on 4th Embodiment of this invention.

Below, this invention is demonstrated based on the embodiment.
In FIG. 1, the structure of the movement state maintenance apparatus unit which concerns on 1st Embodiment of this invention is shown.
In the motion state maintaining apparatus unit 1 shown in FIG. 1, a holding body 13 is disposed across a gap so as to face one magnetic pole 11 a of the main magnet 11, and the holding body 13 is on the opposite side of the main magnet 11. The secondary magnet 12 is held. Further, a holding body 15 is disposed opposite to the other magnetic pole 11 b of the main magnet 11 with a gap therebetween, and the holding body 15 holds the sub magnet 14 on the side opposite to the main magnet 11.

Of the two magnetic poles of the sub-magnet 12, the magnetic pole 12a far from the magnetic pole 11a of the main magnet 11 has a different magnetism from the magnetic pole 11a, and the magnetic pole 12b of the main magnet 11 closer to the magnetic pole 11a is the same as the magnetic pole 11a. Has magnetism. The holding body 13 is made of a magnetic material, and is magnetized so as to have the same magnetism as that of the magnetic pole 12b by being in contact with the magnetic pole 12b of the sub magnet 12.
Similarly, of the two magnetic poles of the secondary magnet 14, the magnetic pole 14a far from the magnetic pole 11b of the main magnet 11 has a different magnetism from the magnetic pole 11b, and the magnetic pole 14b on the side close to the magnetic pole 11b of the main magnet 11 It has the same magnetism as 11b. The holding body 15 is formed of a magnetic material, and is magnetized so as to have the same magnetism as that of the magnetic pole 14b by being in contact with the magnetic pole 14b of the submagnet 14.

  The function of the motion state maintaining apparatus unit 1 when the moving object 30 having magnetism passes through the motion state maintaining apparatus unit 1 will be described. Here, the case where the magnetism of the moving object 30 and the magnetism of the magnetic pole 11a of the main magnet 11 are the same, that is, the case where the magnetic pole 11a of the main magnet 11 becomes a repulsive pole will be described.

If there is no holding body 13 for holding the secondary magnet 12, the moving object 30 at the position A directly receives the repulsive force from the magnetic pole 11a, and enters the magnetic field region of the moving state maintaining device unit 1. If there is a holding body 13 that holds the secondary magnet 12, the moving object 30 approaches the motion state maintaining device unit 1 by the attractive force of the magnetic pole 12 a of the secondary magnet 12. At that time, the lines of magnetic force that generate the repulsive force from the magnetic pole 11a of the main magnet 11 are blocked by the holding body 13, and as shown by the arrows in the drawing, go around the main magnet 11 toward the magnetic pole 11b.
In addition, since the holding body 13 is formed of a magnetic body, most of the lines of magnetic force directed from the magnetic pole 11 a toward the holding body 13 pass through the holding body 13. That is, the lines of magnetic force from the magnetic pole 11 a toward the holding body 13 are confined by the holding body 13 and go to the magnetic pole 12 a of the submagnet 12.

As a result, the lines of magnetic force acting directly on the moving object 30 through the space from the magnetic pole 11a of the main magnet 11 are remarkably reduced, and the moving object 30 is less likely to receive a repulsive force from the magnetic pole 11a, and the movement state maintaining device unit 1 is easily obtained. After that, it is accelerated along the magnetic field lines from the magnetic pole 11a to the magnetic pole 11b and proceeds.
Since the magnetic lines of force that generate the attractive force from the magnetic pole 11b of the main magnet 11 with respect to the moving object 30 that has reached the position B are confined to the holding body 15, they directly act on the moving object 30 from the magnetic pole 11b of the main magnet 11. The lines of magnetic force are significantly reduced, and the moving object 30 travels without being attracted to the magnetic pole 11b of the main magnet 11. Thereafter, the repulsive force received from the magnetic pole 14a of the submagnet 14 is moved away from the motion state maintaining device unit 1.
Therefore, the motion state of the moving object 30 can be maintained by continuously arranging the motion state maintaining device units 1.

FIG. 2 shows a configuration of an exercise state maintaining device unit according to the second embodiment of the present invention.
In the motion state maintaining device unit 2 shown in FIG. 2, a protrusion 16 a is provided at a position where the holding body 13 faces the magnetic pole 11 a of the main magnet 11, and the magnetic pole 11 a of the main magnet 11 and the protrusion 16 a are in contact with each other. . Similarly, a protrusion 16b is provided at a position where the holding body 15 faces the magnetic pole 11b of the main magnet 11, and the magnetic pole 11b of the main magnet 11 and the protrusion 16b are in contact with each other. The shape of the protrusions 16a and 16b may be conical or hemispherical. When such protrusions 16a and 16b are formed, the holding body 13 and the holding body 15 can be magnetized by contact with the main magnet 11, and confinement of magnetic lines of force from the main magnet 11 is promoted. In addition, since the area of the contact portion is very small, the uniqueness of the magnet can be maintained.
The function of the exercise state maintenance device unit 2 shown in FIG. 2 is the same as that of the exercise state maintenance device unit 1 shown in FIG.

FIG. 3 shows a configuration of an exercise state maintaining device unit according to the third embodiment of the present invention.
In the motion state maintaining device unit 3 shown in FIG. 3, a concave portion 17a is provided at the position of the magnetic pole 11a of the main magnet 11, and the bottom surface 18a of the concave portion 17a and the protruding portion 16a are in contact with each other. At this time, the protrusion 16a is not in contact with the side surface 19a of the recess 17a. Similarly, a recess 17b is provided at the position of the magnetic pole 11b of the main magnet 11, and the bottom surface 18b of the recess 17b and the protrusion 16b are in contact with each other. At this time, the protrusion 16b is not in contact with the side surface 19b of the recess 17b.

  The functions of the protrusions 16a and 16b are the same as in the second embodiment, but by providing the recesses 17a and 17b, the protrusions 16a and 16b are brought into contact within the recesses 17a and 17b. At this time, since the degree of freedom of the contact angle is obtained, when setting the motion state maintaining device unit 3 so that the moving object 30 draws the rotation trajectory, the motion state maintaining device is utilized using the degree of freedom of the contact angle. The unit 3 can be arranged so as to draw a rotation trajectory.

FIG. 4 shows a configuration of an exercise state maintaining device unit according to the fourth embodiment of the present invention.
In the motion state maintaining device unit 4 shown in FIG. 4, a core member 20 made of a magnetic material is inserted so as to penetrate both poles of the main magnet 11. The leading end of the core member 20 may be in contact with the holding body 13 and the holding body 15 as shown in the figure, or may be further extended so as to be in contact with the submagnet 12 and the submagnet 14. .
When the core member 20 is used, the motion state maintaining device unit 4 can be integrated by a simple method, which is convenient when the motion state maintaining device unit 4 is fixed to a fixed plate or the like.

  By continuously arranging the motion state maintaining device units described above, it is possible to achieve motion state maintenance according to the motion path and motion form of the moving object. As an example of continuous arrangement of the exercise state maintenance device unit, a case where the exercise state maintenance device unit is arranged linearly or a case where the exercise state maintenance device unit is arranged in a circular shape can be considered.

  INDUSTRIAL APPLICABILITY The present invention can be used as a motion state maintaining device capable of effectively maintaining the motion state of a moving object, and can be used for a rotary pedal or the like.
