Description

  The present invention relates to a magnetic therapy device that includes a coil (magnet generation means) built in a case body having a magnetic action surface, improves blood circulation by magnetism, and is used for health promotion of a person (animal).

2. Description of the Related Art Conventionally, an electromagnetic health promoter that includes a plurality of electromagnets and promotes blood circulation is known (see Patent Document 1).
The electromagnetic health promoter is configured to vary a current or a voltage applied to a plurality of electromagnets and at least one electromagnet coil of the plurality of electromagnets, and to at least one other electromagnet coil of the plurality of electromagnets. A magnetic force control means capable of supplying a current or voltage of a certain strength and a flat protective plate covering the magnetism generating portion, and the magnetic force of a plurality of electromagnets inside the flat protective plate is effective for the human body. And a box formed by arranging a plurality of electromagnets at the position of the irradiated magnetism generating portion.

JP 2004-329584 A

However, the electromagnetic health promoter described in Patent Document 1 includes a planar heating element disposed between the box inner surface side of the planar protection plate and each electromagnet, and between the planar heating element and each electromagnet. A heat insulating material is also provided that covers the planar heating element.
That is, this electromagnetic health promoter requires three layers of a heat insulating material, a planar heating element, and a planar protective plate, and the magnetism from the electromagnet does not reach the human body without passing through these three layers.
This is because the electromagnetic health promoter of Patent Document 1 intends to reduce the magnetic force of the electromagnet to less than 350 [Gauss] (Patent Document 1, paragraph [0003]) and is inversely proportional to the square of the distance. The magnetic force is weakened accordingly, and the efficiency of magnetism generation is very poor.
Even if one of the three layers is reduced to bring the electromagnet closer to the human body in order to improve the magnetic efficiency, the strength of the box is reduced by the reduced layer.

  In view of these points, the present invention covers the outer surface opening of the magnetic through hole into which one end of the iron core of the coil (magnetism generating means) enters with a covering sheet having a substantially flat back surface on the case body side. It is an object of the present invention to provide a magnetic treatment device that achieves both “improvement of magnetic efficiency” and “maintenance of case strength” and further “improvement of manufacturing efficiency” by bringing one end of an iron core close to each other.

  The magnetic therapy device 1 according to the present invention includes a case body provided with a magnetic action surface and a cylindrical coil built in the case body, and one end of the iron core projects from one end of the coil, and the iron core One end portion of the through hole enters the through hole that penetrates the magnetic acting surface side of the case body in the thickness direction from the inner surface opening, and the outer surface opening of the through hole is covered with a covering sheet whose back surface on the case body side is substantially flat. The first feature is that the tip of one end of the iron core is close to the covering sheet.

  A second feature of the magnetic therapy device 1 according to the present invention is that, in addition to the first feature, the covering sheet is attached in an outer recess formed in a magnetic action surface of the case body, and the case The magnetic action surface of the body is substantially flush.

  A third feature of the magnetic therapy device 1 according to the present invention is that, in addition to the first or second feature, the back surface of the covering sheet is attached to the case body via an adhesive, and the adhesive is In the back surface of the covering sheet, a portion corresponding to the through hole is avoided.

  A fourth feature of the magnetic therapy device 1 according to the present invention is that, in addition to any of the first to third features, both ends of the coil abut against the inner surface of the case body, and the magnetic action surface of the case body. It is in the point which regulates the dent to the inner surface side.

Due to these characteristics, the outer surface opening 8c of the through-hole 8 into which the one end portion 7a of the iron core 7 of the coil (magnetic generating means) 3 enters is covered with the covering sheet 16, and the one end portion 7a of the iron core 7 is covered with the covering sheet 16. By making them close to each other, the two-layer structure of the case body 2 and the covering sheet 16 is formed on the magnetic acting surface 2a side, and the strength of the two layers of the case body 2 can be secured, and at the same time, the one end 7a of the iron core 7 is covered The distance to the surface (human body or the like) of the sheet 16 becomes a distance corresponding to the thickness of the covering sheet 16 itself, and the intensity of magnetism generated for a predetermined input power is increased.
That is, it is possible to achieve both “improvement of magnetic efficiency” and “maintenance of case strength”.

In addition, in order to shorten the distance to a human body etc., the structure which forms a bottomed hole, a dent, etc. in case body 2 itself (it does not cover with the coating sheet 16) is also considered.
As a method of forming such a bottomed hole, etc., there is integral molding, but in integral molding, resin or foam is poured between molds, so if the distance between molds is too narrow, resin between them Etc. do not reach sufficiently, and there is a limit to the thinness of the thin part (bottom of the hole etc.) by integral molding. Moreover, although a bottomed hole etc. can be formed by cutting with a drill etc., a manufacturing process and manufacturing cost increase only by the part for cutting.
However, in the present invention, by using the covering sheet 16 whose back surface 16a is substantially flat (that is, the covering sheet 16 has no bottomed holes, dents, etc.), the limit of thinness such as integral molding is limited to the covering sheet. 16, the one end 7 a of the iron core 7 can be brought closer to the human body or the like (improving magnetic efficiency), and it is only necessary to cover the outer surface opening 8 c of the through-hole 8 with the covering sheet 16. The manufacturing burden can be reduced compared with the case of (making manufacturing more efficient).
Accordingly, it is possible to further improve “production efficiency” while achieving both “improvement of magnetic efficiency” and “maintenance of case strength”.
In addition, the back surface 16a of the coating sheet 16 in the present invention is “substantially flat”, and at the beginning of manufacture, the back surface 16a abuts on the tip (top surface 9) of the upper end portion 7a of the iron core 7 and is slightly scraped ( It also includes the case where it has been depressed.

  Also, the appearance of the magnetic action surface 2a side is improved by attaching the covering sheet 16 in the outer recess 17 formed on the magnetic action surface 2a of the case body 2 so that the magnetic action surface 2a is substantially flush. At the same time, the covering sheet 16 can be prevented from peeling off.

  Furthermore, the back surface 16a of the covering sheet 16 is affixed to the case body 2 via the adhesive 18, and the adhesive 18 is present on the back surface 16a of the covering sheet 16 while avoiding the portion corresponding to the through-holes 8; Since there is no layer (adhesive layer 18a) formed by the adhesive 18, the one end 7a of the iron core 7 can be brought closer to a human body or the like.

  Then, both ends 4a and 4b of the coil (magnetism generating means) 3 are brought into contact with the inner surface of the case body 2 to restrict the indentation of the case body 2 toward the inner surface side of the magnetic action surface 2a. Can also be used as a support for supporting the magnetic acting surface 2a of the case body 2.

The case body 2 in the present invention is made of synthetic resin such as silicon resin and nylon (polyamide) polymer, and engineering plastic such as polyacetal and polycarbonate, and the shape thereof is a substantially rectangular parallelepiped shape, from the middle in the thickness direction. In addition, a flat plate (a flat plate portion 23 described later) extends in a substantially horizontal direction. Further, the case body 2 can be divided vertically and includes a lower case body 21 and an upper case body 22.

<Lower case body 21>
As shown in FIGS. 1 to 3, the lower case body 21 is a container-like member that supports the magnetism generating means 3 having the two coil bobbins 6 and 6 from below and is substantially rectangular in plan view, and has a pair of long sides Flat plate portions 23, 23 extending in a substantially horizontal direction from the upper end portion of the outer side surface are provided in a pair (front and rear).
The flat plate portion 23 is also substantially rectangular in a plan view, and has a hole (a round hole 23a through which a screw or the like passes, a long hole 23b through which a belt-like member or the like passes) or the like penetrating in the thickness direction. It may be done.

On the inner bottom surface of the lower case body 21, a pair of locking pieces 24, 24 that stand and hold the magnetism generating means 3, in particular, a substantially prismatic iron core body 11 of the iron core 7 to be described later, are erected. Yes.
Each of the pair of locking pieces 24, 24 is substantially U-shaped in a plan view, and each locking piece 24 has locking piece branch portions 24b, 24b provided at both ends of the locking piece body portion 24a. Are deployed to face each other.
Therefore, when the core body 11 is placed between the locking pieces 24, the magnetism generating means 3 is supported at a predetermined position, that is, the magnetism generating means 3 does not move downward (the magnetism generating means (coil ) The lower end of 3 is supported by abutting the inner surface of the case body 2, and the projecting end 7 a of the iron core 7 on the upper surface side of the magnetism generating means 3 penetrates the inner surface of the upper case body 22 at a predetermined position where the support is supported. The position corresponds to the magnetic hole 8.

In addition to this, it is disposed between the lower case body 21 (between the locking pieces 24 and 24) and each magnetism generating means 3 (an iron core body 11 to be described later), and each magnetism generating means 3 is placed upward. It has a spring plate 25 for urging the spring. The spring plate 25 may not be provided.
The case body 2 is provided with a cord hole 26 through which the cord 20 for supplying power to the magnetism generating means 3 is inserted from the inside of the case body 2 to the outside. The lower half of the cord hole 26 is formed. A lower notch 27 is provided on one of the four side surfaces of the lower case body 21 by cutting the side surface downward in a substantially semicircular shape.

Fixed cylindrical bodies 29 are erected at the four corners of the inner bottom surface of the lower case body 21, and the upper and lower case bodies 21, 22 are integrally fixed by screws or the like inserted into a fixing hole 30 described later of the upper case body 22. Is done.
If the upper and lower case bodies 21 and 22 are integrally fixed, they are not limited to the configuration of the fixed cylindrical body 29, the fixing hole 30, and screws, but may be integrally fixed by fitting or bonding.

<Upper case body 22>
As shown in FIGS. 1, 2, and 4, the upper case body 22 is a lid-like member that covers the magnetic generator 3 having the two coil bobbins 6 and 6 and has a substantially rectangular shape in plan view.
The outer upper surface of the upper case body 22 constitutes a planar magnetic action surface 2 a in the case body 2.

The magnetic action surface 2a is provided with a pair of (left and right) through-holes 8 and 8 penetrating the upper surface side of the upper case body 22 in the thickness direction. The projecting one end portion 7a of the iron core 7 in the generating means 3 is set to a size that allows entry.
Each through-hole 8 is substantially circular in plan view, and the iron core 7 of the magnetism generating means 3 positioned by the locking pieces 24, 24 of the lower case body 21 at a position slightly deviated from the approximate center of this circle. It is located at one end 7a that protrudes (particularly, the top surface 9 of the one end 7a).

The penetration length of the through-hole 8 is, of course, substantially the same as the thickness on the upper surface side of the upper case body 22, and the length at which one end portion 7 a of the iron core 7 protrudes from one flange portion 4 of the coil bobbin 6. Also, it is almost the same.
In addition to this, the inner peripheral surface 8 a of the through-hole 8 is formed in a substantially straight cylindrical shape along the vertical direction (vertical direction), and the inner peripheral surface 8 a is formed from the inner surface opening 8 b of the through hole 8. The outer end opening 8c may be formed so as to have an upper end spreading shape in which the diameter increases (as the diameter increases toward the upper side), or may be formed in a lower end expanding shape.

The outer surface openings 8 c of the pair of through-holes 8, 8 described above are covered with the covering sheet 16.
When the covering sheet 16 is affixed to the upper case body 22, the upper case body 22 has an outer upper surface (the magnetic action surface 2a) recessed by a predetermined range so that the magnetic action surface 2a is substantially flush. An outer recess 17 is provided.
The shape of the outer recess 17 in plan view is similar to and slightly smaller than the cover sheet 16 in plan view, and the depth of the outer recess 17 is substantially the same as the thickness of the cover sheet 16.
Thus, by sticking the covering sheet 16 in the outer recessed portion 17 and making the magnetic acting surface 2a substantially flush, not only the appearance (appearance) on the magnetic acting surface 2a side is improved, but also the covering sheet 16 Since the end face is not exposed, peeling of the covering sheet can be suppressed.

The magnetic action surface 2a is not necessarily flat, including the covering sheet 16 that is affixed to the magnetic action surface 2a. The magnetic action surface 2a is adapted to the shape of the user's waist, shoulders, arms, legs, etc. Even a curved surface in which a depression is formed may be a surface composed of both such a curved surface and a flat surface.
Further, the outer surface opening 8 c of each through hole 8 described above is located in the bottom surface of the outer recess 17.

Further, the two adjacent ones of the coil bobbins 6 and 6 of the two magnetism generating means 3 are fitted to the inner surface (inner upper and lower surface) of the upper case body 22 on the magnetic action surface 2a side. The recessed portion 13 that can be positioned is also formed.
The recess 13 is substantially rectangular in plan view, and is recessed so as to surround both of the two adjacent flanges 4 and 4 from the outside.
If two adjacent flanges 4, 4 are assigned to the recessed portion 13 thus recessed, the projecting one end 7 a of the iron core 7 in the magnetism generating means 3 becomes a position corresponding to each through-hole 8. .
Thus, by forming the concave portion 13 that can position the flange portions 4 and 4 of the two coil bobbins 6 and 6 on the inner surface on the magnetic action surface 2a side, the plurality of magnetism generating means 3 can be positioned simultaneously (that is, Assembling is easy while securing the strength of the case body 2.

In the upper case body 22, an upper notch 28 that forms the upper half of the above-described cord hole 26 is provided in one of the four side surfaces of the upper case body 22 (position corresponding to the lower notch 27). The side surface is provided by cutting out upward in a substantially semicircular shape.
In addition, fixing holes 30 penetrating the four corners are provided on the inner upper bottom surface of the upper case body 22, and screws or the like passing through the fixing holes 30 are screwed into the fixing cylinder body 29 of the lower case body 21. Thus, the upper and lower case bodies 21 and 22 are integrally fixed.
Of course, as described above, the integral fixing of the upper and lower case bodies 21 and 22 is not limited to fixing means using screws or the like as long as they can be fixed.

<Coating sheet 16>
As shown in FIGS. 1 and 2, the covering sheet 16 is sized to cover the pair of through-holes 8 and 8, and the adhesive 18 Is pasted through. Even if the covering sheet 16 is large enough to protrude from the magnetic acting surface 2a, it does not matter as long as it covers each through hole 8.
The shape of the covering sheet 16 in a plan view is not particularly limited, but for example, a substantially 8-shaped figure that is concentrically arranged in a large and small shape is drawn on the upper surface (surface) to form a pattern in which the lines of magnetic force are imaged.
However, this pattern may be composed only of concentric circles or single circles, or may not be formed.

The covering sheet 16 is composed of a resin film, a paper material, a non-magnetic metal thin plate, and the like, and more specifically, a synthetic resin film such as polyethylene terephthalate (PET), polypropylene, polyvinyl chloride (PVC), and the like. On the surface of the synthetic resin film (surface) with aluminum vapor deposition and hologram processing, and various papers mainly composed of pulp (cellulose fiber) (quality paper, art paper, craft paper, Japanese paper, etc.) Also, the surface of these papers subjected to aluminum vapor deposition, or non-magnetic metal thin plates such as gold, silver, copper, aluminum, and magnesium may be used.
The thickness of the covering sheet 16 composed of these materials is 0.05 mm or more and 1.00 mm or less, preferably 0.07 mm or more and 0.7 mm or less, and more preferably 0.1 mm or more and 0.5 mm or less.

The covering sheet 16 may be a sealing body in which an adhesive 18 is applied or impregnated on the back surface 16a side of the above-described material sheet. In this case, a layer (adhesive layer) 18a formed by the adhesive 18 is provided. Will be formed.
Note that release paper may be provided on the back surface (surface on the case body 2 side) of the adhesive layer 18a of the covering sheet 16 (sealing body), and the case body 2 (upper case body 22) may be provided during manufacture. When affixing to the cover sheet, the cover sheet 16 can be easily affixed by peeling the release paper, and at the same time, the handling and management of the cover sheet 16 before the affixing is facilitated.

Since the covering sheet 16 has at least a back surface (surface on the case body 2 side (surface attached to the upper case 22)) 16a being substantially flat, the thickness of the covering sheet 16 is determined by the magnetic generation means. 3 is the distance from the tip (top surface 9) of the upper end 7a of the iron core 7 to the human body outside the case body 2.
If the back surface 16a of the cover sheet 16 is substantially flat, that is, the cover sheet 16 is not provided with a bottomed hole or dent opened upward from the back surface 16a, and the tip of the upper end portion 7a of the iron core 7 ( To bring the top surface 9) close to each other means that the upper case body 22 bears only on the through-hole 8 side.

Thus, since the covering sheet 16 having no bottomed hole or the like from the back surface 16a can be dedicated to obtaining only “thinness” by an easy manufacturing method, foaming of the above-described synthetic resin, polyurethane, PET, or the like. There is no limit of thinness as in the case where the body is formed into a sheet by integral molding.
In addition, since only the process of covering the outer surface opening 8c of the through hole 8 with the prepared covering sheet 16 is necessary, a bottomed hole or the like is cut in the upper case body 22 (cutting is stopped halfway). Compared to the cutting process to be formed, the manufacturing burden can be reduced (making manufacturing more efficient).
Accordingly, it is possible to further improve “production efficiency” while achieving both “improvement of magnetic efficiency” and “maintenance of case strength”.

In addition, the back surface 16a of the coating sheet 16 in the present invention is “substantially flat”, and at the beginning of manufacture, the back surface 16a abuts on the tip (top surface 9) of the upper end portion 7a of the iron core 7 and is slightly scraped ( It also includes the case of a depression.
Further, the covering sheet 16 is bent or depressed from the front surface (that is, the magnetic acting surface 2a) side after being attached to the upper case body 22 even if both the front surface and the back surface 16a are substantially flat at the beginning of manufacture. If the back surface 16a side is substantially flat even if it is made or is scraped downward, it is included in the “coating sheet 16” in the present invention.

<Magnetic generation means (coil) 3>
As shown in FIGS. 1 to 4, the magnetism generating means 3 according to the present invention includes two coil bobbins 6, 6 that are electromagnets, and a substantially U-shaped iron core 7 fitted into the two coil bobbins 6, 6. ing.

<Coil bobbin 6>
The coil bobbin 6 in the magnetism generating means 3 is made of a synthetic resin such as silicon resin or nylon (polyamide) polymer, or an engineering plastic such as polyacetal or polycarbonate, and the spool portion 5 into which the iron core 7 can be fitted, and the same synthetic resin. And includes hooks 4 and 4 provided at both ends (upper and lower ends) of the spool portion 5 and electric wires wound around the outer peripheral surface of the spool portion 5.
The spool portion 5 in the coil bobbin 6 is a rectangular tube-shaped member having a substantially square cross section, and the cross sectional shape and cross sectional area in the cylinder are slightly larger than the cross sectional shape and cross sectional area of the iron core 7 (iron core branch portion 12). It is almost the same.

Therefore, the spool portion 5 is fixed to the iron core 7 (iron core branch portion 12) by fitting, double-sided tape, adhesive, or the like.
The spool portion 5 is arranged so that the axial center of the spool portion 5 extends along the vertical direction with respect to the case body 2 via the substantially U-shaped iron core 7.

FIG. Thus, the coil bobbin 6 is positioned with respect to the iron core 7, and the insertion depth of the iron core branch portion 12 into the spool portion 5, that is, the protruding length of one end portion 7a of the iron core 7 protruding from the upper collar portion 4 is defined. To do.

In addition, the latch pins 10 are provided as a pair of two each at a predetermined interval on each side end face 4c. In this case, the winding is wound in either the left or right direction with respect to the spool portion 5. (The direction of the wire to be wound can be either right-handed or left-handed), increasing the degree of freedom of work and reducing the work process.

Furthermore, on each side end surface 4c, a convex portion that changes the direction in which the electric wire is hooked and wound may be provided between the two latch pins 10 and 10 (substantially intermediate position).
In addition, of the pair of side end surfaces 4c facing each other, the distance between the pair of latch pins 10 and 10 provided on one side end surface 4c (the distance between the pins) is set as the other side end surface. It is set to be smaller or larger (narrow or wide) than the distance between the two provided latch pins 10 and 10 (distance between the pins) (that is, different). The difference in distance is also referred to in the second embodiment).
One hook pin 10 may or may not be provided on each side end surface 4c.
Moreover, in order to make the front-end | tip (top surface 9) of the upper end part 7a of the iron core 7 approach the back surface 16a of the coating sheet 16, the upper collar part 4a and the lower collar part 4b are made thin, or the spool part 5 is shortened. You may do it.

When this electric wire is wound around the spool portion 5, it may be any of manual winding, a winding device, and the like. In addition, when using the winding device for aligned winding, it is necessary to apply tension to the wire to some extent, and unless the wire is stretched, clean aligned winding cannot be performed. Alternatively, it may be temporarily fixed with a tape or entangled with the above-described latch pin 10.

<Crossover 19 / Code 20>
As shown in FIGS. 1, 3, and 4, the crossover wire 19 includes two adjacent (adjacent) coil bobbins 6, two of which are erected on the side end surface 4 c of the lower flange portion 4 b of one coil bobbin 6. A total of four latch pins 10, 10 and two latch pins 10, 10 on the other coil bobbin 6 erected on the side end surface 4 c on the same side as the two latch pins 10, 10. The latch pins 10 to 10 are attached via solder or the like.
Further, another crossover wire 19 is attached to the other four latching pins 10 to 10 which are erected on the side end surface 4c at a position opposite to the four latching pins 10 to 10. The two coil bobbins 6 and 6 are sandwiched between two crossover wires 19 and 19 in plan view.

The crossover wire 19 is positioned below the four latch pins 10 to 10, but may be attached above each latch pin 10, and each latch pin 10 may be sewn. It may be spread alternately up and down.
Of the four latch pins 10 to 10 over which one spanning wire 19 is stretched, the ones that can actually wind the winding start and end wires are the winding start and winding of the two coil bobbins 6 respectively. A total of two electric wires at the end, but the attachment strength is improved by attaching four crossover wires 19 together.
A cord 20 is connected to one end of each of the two connecting wires 19, 19 extending between the two coil bobbins 6, 6 (one magnetism generating means 3), and these cords 20 (two cords 20, 20) through the ON / OFF switch, timer, etc., the magnetic field is applied to the magnetic action surface 2a of the case body 2 by the electric power supplied from the cord hole 26 from the commercial power source (50 Hz or 60 Hz) outside the case body 2. generate.

<Iron core 7>
As shown in FIGS. 1 to 4, the iron core 7 in the magnetism generating means 3 is formed in a substantially U shape, and has a substantially prismatic (substantially square shape in cross section) iron core body 11, and the iron core body 11. Are provided with iron core branch portions 12 and 12 provided at both ends (right and left ends). Each of the iron core branches 12 is also substantially prismatic (substantially square in cross section).
That is, from the left and right ends of the core body 11 having the longitudinal direction, each core branch section 12 extends in a direction perpendicular to the longitudinal direction of the core body 11 and upward, and is substantially U-shaped (horse-shoe). Is made.
The iron core 7 is configured so that a thin plate such as soft iron is cut out into a predetermined shape and overlapped to have a certain thickness.

Moreover, the upper end part (one end part of the protruding iron core 7) 7a of each iron core branch part 12 is a taper shape, has the top surface 9 in the foremost end, and gradually thickens from this top surface 9 toward the root. Is formed.
Furthermore, the shape of the upper end portion 7a is configured to taper not only in the front view of the iron core 7, but also in the side view.
Therefore, first, a configuration in front view of the upper end portion 7a of each iron core branch portion 12 will be described.

When the upper end portion 7a of the iron core branch portion 12 is viewed from the front, the top surface 9 is substantially flat and substantially horizontal, the vertical surface 31 is continuous with the top surface 9, and the inclined portion is located on the opposite side of the vertical surface 31. 32.
The vertical surface 31 in the upper end portion 7 a is a vertical surface that is provided on the side (inner side) where the pair of left and right iron core branches 12, 12 face each other and continuously extends upward from both ends of the upper surface of the iron core body 11. .

The inclined portion 32 in the upper end portion 7a is provided on the side (outside) of the pair of left and right iron core branches 12 and 12 that do not face each other, and increases from the outside toward the side where each iron core branch 12 approaches. It is inclined.
Further, the inclined portion 32 includes an upper upper inclined surface 33 positioned on the inner side of each iron core branch portion 12, a lower lower inclined surface 34 positioned on the outer side of each iron core branch portion 12 with respect to the upper inclined surface 33, A flat surface 35 is provided between the two inclined surfaces 33 and 34.

  In addition, the shape when the upper end portion 7a is viewed from the front does not have to include the upper inclined surface 33, the lower inclined surface 34, and the flat surface 35 as described above. The upper inclined surface 33 and the lower inclined surface 34 continuously constitute one inclined portion (inclined surface) 32, or the upper inclined surface 33 and the flat surface 35 alone constitute the inclined portion 32, and the lower inclined surface Various shapes can be adopted as long as the shape is tapered, such as a case where 34 is not provided.

On the other hand, in a side view at the upper end portion 7a of each core branch 12, two types of thin plates constituting the core 7 are used, both long and short, in the thickness direction (side view) of the core 7. It is comprised so that.
That is, the pointed portion in a side view is configured by sandwiching several thin plates with a long core branch 12 and sandwiching several thin plates with a short core branch 12 from the front and rear.
Of course, the thickness of the pointed portion in this side view (the upper end portion of a laminate of several thin plates having a long iron core branch portion 12) is the other portion of the iron core 7 such as the iron core trunk portion 11 (the iron core branch portion 12 is long). The laminated body is thinner than the portion sandwiched between the laminated cores with the short core branches 12, and is, for example, 1/3 or more and 2/3 or less of the thickness of other portions.

Thus, by forming the protruding upper end portion 7a of the iron core 7 in a tapered shape, the magnetic flux density from the magnetic emission end increases, and as a result, the magnetic force (Gauss) to be emitted increases.
That is, when the magnetic flux generated in the iron core 7 is energized to the electric wire of the coil bobbin 6, it passes through a narrower space when it exits from the pointed upper end 7 a, so that the magnetic flux density in the space is increased, The magnetic force (Gauss) in the magnetic field increases.

Further, no magnetic field lines are radiated from the inclined part 32 of the upper end part 7a, and all the magnetic field lines come out from the top surface 9 provided at the tip of the small sharp part, so that the top surface 9 having a small area of magnetic field lines. The magnetic force is also increased by radiating from the center.
The current flowing through the coil bobbin 6 may be an alternating current having a predetermined frequency (for example, 50 Hz, 60 Hz, or other frequency) and amplitude. In this case, the magnetic polarity is switched from the coil bobbin according to the frequency. However, an alternating magnetic field in which the magnetic flux density changes with time is generated.
Furthermore, the current that flows through the wire of the coil bobbin 6 is a pulse current in which a current having a predetermined value intermittently flows at a predetermined cycle, for example, a pulse current having a triangular waveform that instantaneously rises or falls gently. In this case, the magnetic flux change is larger than the alternating current having a sine wave-like gentle waveform. In addition, since positive current is generated only positively if it is positive, and negative current is generated intermittently if it is negative, the magnetic flux changes more than when alternating positive and negative currents, such as alternating current. It is difficult to cancel.

In addition to this, the top surface 9 formed on the upper end portion 7a of the iron core 7 is substantially flat and substantially horizontal, and the back surface 16a of the covering sheet 16 covering each through-hole 8 is similarly substantially flat. Since it is substantially horizontal, the top surface 9 of the upper end 7a and the back surface 16a of the covering sheet 16 are opposed to each other.
Accordingly, it is possible to prevent the case 7 from penetrating through the magnetic action surface 2a side of the case body 2 at a pointed portion (for example, an edge portion separating the top surface 9 and the upper inclined surface 33) at the upper end portion 7a of the iron core 7, and the iron core 7 The top surface 9 of the one end portion 7 a abuts on the back surface 16 a of the facing cover sheet 16, and the magnetic action surface 2 a of the case body 2 is supported between the top surface 9 and the cover sheet 16.
Further, in order to bring the tip (top surface 9) of the upper end portion 7a of the iron core 7 closer to the back surface 16a of the covering sheet 16, each core branch portion 12 of the iron core 7 may be extended.

In the present invention having the configuration described so far, the protruding upper end 7a of the iron core 7 in the magnetism generating means 3 is made to enter the through-hole 8 formed in the inner surface of the upper case body 22 on the magnetic action surface 2a side. Then, the outer surface opening 8c of the through-hole 8 is covered with the covering sheet 16, and the one end portion 7a of the iron core 7 is brought close to the covering sheet 16, so that the case body 2 and the covering sheet 16 are formed on the magnetic action surface 2a side. With the two-layer structure, the strength of the two layers of the case body 2 can be secured, and at the same time, the distance from the one end portion 7a of the iron core 7 to the surface of the covering sheet 16 (human body, etc.) is equal to the thickness of the covering sheet 16 itself. Thus, the magnetic intensity generated for a given input power is increased.
That is, it is possible to achieve both “improvement of magnetic efficiency” and “maintenance of case strength”.

By improving the magnetic efficiency, the magnetic treatment device 1 having a maximum magnetic flux density of 1800 gauss (180 millitesla) can be obtained, and at the same time, both the “supporting the case body column by the magnetism generating means” and “improving the magnetic efficiency” can be realized.
In addition, the case body 2 in 1st Embodiment may be a size which rides on a palm, and in this case, for example, a belt-like member is formed on the flat plate portion 23 (for example, a long hole 23b penetrating in the thickness direction) of the case body 2 or the like. By attaching (inserting) to the belt type, it is easy to apply it to a part of the human body (knee, waist, shoulder, etc.), and it becomes easy to concentrate and partially apply magnetism at a pinpoint.
Further, the upper flange portion 4a is brought into contact with the inner surface of the upper case body 22 on the magnetic action surface 2a side, so that the dent on the inner surface side of the magnetic action surface 2a is regulated by the magnetism generating means 3 to generate magnetism. The means 3 is also used as a support for supporting the magnetic action surface 2a of the case body 2, and further case strength can be maintained.

Second Embodiment
5 to 7 show a magnetic therapy device 1 according to a second embodiment of the present invention.
The second embodiment is most different from the first embodiment in that the number of coil bobbins 6 is four, which is twice.
Specifically, the second embodiment has two (two sets) of magnetism generating means (coils) 3 configured by fitting two coil bobbins 6 and 6 into a substantially U-shaped iron core 7, respectively. Yes.

Thus, since the second embodiment has four coil bobbins 6 (two magnetism generating means 3), in the second embodiment, the concave portion for positioning the magnetism generating means 3 by the upper case body 22 is the first embodiment. Bigger than.
That is, in the second embodiment, the large concave portion 14 that can be positioned by fitting all the one flange portions 4 to 4 adjacent to each other in the front, rear, left, and right sides of the four coil bobbins 6 to 6 in the two magnetism generating means 3 has a case body. 2 is formed on the inner surface of the magnetic action surface 2a side.
Furthermore, the large concave portion 14 of the second embodiment has a flange 15 formed so as to partition the large concave portion 14 itself into each concave portion 13 for each magnetic generating means 3.

<Flange 15>
As shown in FIG. 7, the flange 15 in the second embodiment is capable of positioning the flanges 4 to 4 of the two sets of magnetism generating means 3 and 3, and the inner bottom surface of the large concave portion 14 having a substantially square shape in plan view ( It is formed inwardly projecting from the inner surface on the magnetic acting surface 2a side.
The flange 15 is a pair of protrusions formed at a predetermined interval, and is provided at a position where the substantially square-shaped large concave portion 14 is divided in substantially half, and has a substantially square shape (with four edges). The approximate center position of one edge portion of the large recess 14 is connected to the approximately center position of the edge portion at a position facing the edge portion.
Thus, by dividing the large concave portion 14 evenly, easy positioning can be performed for each of the magnetism generating means 3 even when a total of four coil bobbins 6 are used.

The protruding height of the flange 15 is substantially the same as the depth of the large concave portion 14, and the protruding end surface (lower end surface) of the flange 15 is the inner surface of the upper case body 22 on the magnetic action surface 2 a side and is the large concave portion. 14 is substantially the same height position (substantially flush) as portions other than 14.
With such a flange 15, even when a load is applied to the upper surface (magnetic action surface 2 a) of the case body 2 (pressed downward), the magnetic action surface 2 a moves downward. That is, the dent to the inner surface side can be suppressed.

Therefore, in the second embodiment, the flange 15 enables the strength of the magnetic action surface 2a in the case body 2 to be improved simultaneously with easy positioning of the four coil bobbins 6.
In each recess 13 formed by partitioning the large recess 14 with the flange 15, the adjacent upper collar portions 4 a and 4 a of each magnetism generating means 3 are applied to the edge of each recess 13 (large recess 14) and the flange 15. For example, the protruding upper end 7 a of the iron core 7 in the magnetism generating means 3 comes to a position corresponding to each through hole 8 of each recess 13.

As shown in FIGS. 5 and 6, in addition to the flange 15, the second embodiment includes an upper bottom portion 41 that protrudes significantly upward from the inner bottom surface of the lower case body 21.
The thickness of the case body 2 can be adjusted by the degree of the upward protrusion of the upper bottom portion 41. For example, by making the thickness of the case member 2 substantially the same as that of the cushion member fixed to the substrate, the magnetic treatment of the present invention. If the container 1 is attached to the substrate and the periphery thereof is surrounded by a cushion member such as a mat or a futon (if it is a seat cushion type having a predetermined spread), the cushion surface of this cushion member and the magnetic action surface 2a are substantially Become one.

Further, even when the magnetism generating means 3 is incorporated in the case body 2 having various thicknesses and sizes, the difference in thickness of each case body 2 is offset by the bulge of the upper bottom portion 41, and each case body 2. The configuration of the magnetism generating means 3 used in the above (such as vertical height) can be made common, leading to cost reduction.
In addition to this, in the second embodiment, the magnetism generating means 3 (iron core body 11) and the lower case body 21 (between the locking pieces 24, 24) are arranged, and each magnetism generating means 3 is arranged. A pair of spring plates 44, 44 that urge upward is provided. The spring plate 44 may not be provided.
In the second embodiment, contrary to the first embodiment, the fixing holes 30 are provided at the four corners of the lower case body 21, and the fixing cylinders 29 are provided at the four corners of the upper case body 22. The upper and lower case bodies 21 and 22 are integrally fixed by screwing a fixing means such as a screw through the fixing hole 30 and the fixing cylinder body 29 from below.

In the second embodiment, as in the first embodiment, a pair of latch pins 10 and 10 are erected on each side end face 4c of the four coil bobbins 6 to 6, and the distance between these pins is a position where they face each other. Although they are set to be different from each other, the distance between the pins is different, and the two magnetism generating means 3 and 3 are used for compacting.
Specifically, in each magnetism generating means 3, the distances between the pins of the two coil bobbins 6 and 6 are staggered (that is, the distance between the pins is different between the pair of adjacent latch pins 10 and 10). N) It is inserted into the substantially U-shaped iron core 7.
If the crossing pins 19 are close to each other with the two magnetism generating means 3 and 3 between such alternate pins, the distance between the pins is increased between the pair of latching pins 10 and 10. The pair of latching pins 10 and 10 having a narrow distance between the pins are naturally positioned so that the two magnetism generating means 3 and 3 can be brought closer to each other (of the magnetism generating means 3 and 3). Compact).

Further, as shown in FIGS. 5 and 6, a pair of cutout portions 42, 42 cut downward in a substantially rectangular shape are provided on opposite side surfaces of the lower case body 21, and the pair of cutout portions 42, A pair of projecting pieces 43, 43 projecting downward are provided at corresponding positions on the side surface of the upper case body 22 of 42.
A flange 43a that tapers in the thickness direction as it approaches the tip of the protruding piece 43 from a position thicker than the other portions of the protruding piece 43 is provided on the outer surface of the tip of each protruding piece 43. Each protruding piece 43 can bend in the direction in which 43a moves to the inner surface side of the case body 2.

Accordingly, a case in which the upper and lower case bodies 21 and 22 are integrally fixed in a state in which the protruding pieces 43 and 43 are inserted into the notches 42 and 42 described above, thereby providing a flange portion 43a that can be withdrawn and retracted on the side surface portion.
