Description

[Technical field]

[0001] The present invention relates to a magnet for magnetic therapy. [Background technology]

[0002] Conventionally, as disclosed in Patent Document 1, for example, a magnetic therapy device is used that is attached to the skin of the human body to exert a magnetic therapy effect on the human body. The magnetic therapy device of Patent Document 1 includes a disk-shaped magnet and an adhesive sheet attached to the magnet, and is used by attaching the magnet to the skin of the human body with the adhesive sheet. The disk-shaped magnet has high side walls and is thick overall in order to generate a large magnetic force, and is formed so that the thickness of the center part is the largest. This disk-shaped magnet has the largest magnetic force in the center part, which has the largest thickness, and can exert a high magnetic therapy effect by positioning the center part at the part of the human body where the magnetic therapy effect is desired.

[0003] [Patent Document 1] JP 2005-296455 A Summary of the Invention [Problem to be solved by the invention]

[0004] The magnetic therapy device of Patent Document 1 is attached to the skin of the human body so that the magnet is pressed by the adhesive sheet. At this time, the magnet is positioned so that it enters the part of the skin that is recessed by the magnet's pressure and the side wall of the magnet engages with the skin. The magnetic therapy device is attached to the skin of the human body for a long period of time, and if a force is applied during that period that moves the magnet relative to the skin, the side wall of the magnet may come into contact with the skin, causing pain.

[0005] As described above, the magnet of the magnetic therapy device of Patent Document 1 is formed so that it is thickest at its center and generates the strongest magnetic force. However, since the part with the strongest magnetic force is limited to one point at the center, it may be difficult to position this center at the part of the human body where the magnetic therapy effect is desired.

[0006] The present invention has been made in consideration of the above problems, and aims to provide a magnet for magnetic therapy that, when attached to the skin of the human body, suppresses the occurrence of pain and can exert a large magnetic force on multiple locations. [Means for solving the problem]

[0007] The magnetic therapy magnet of the present invention is a magnetic therapy magnet that is attached to the skin of the human body and used, and is characterized in that the magnetic therapy magnet has a main body portion formed in an approximately conical shape and a plurality of protrusion portions formed and spaced apart from each other on the side of the main body portion.

[0008] It is also preferable that the plurality of protrusions are formed so that the heights of the top ends of the plurality of protrusions are substantially the same.

[0009] It is also preferable that the plurality of protrusions are formed so that the top ends of the plurality of protrusions are at substantially the same height as the top end of the main body.

[0010] It is also preferable that the main body portion has an approximately partially spherical top portion having a first radius of curvature, and the protrusion portion is formed in an approximately partially spherical shape having a second radius of curvature, the second radius of curvature being smaller than the first radius of curvature.

[0011] It is also preferable that the plurality of protrusions are provided on a side surface above the midpoint of the main body.

[0012] It is also preferable that the main body portion has a substantially truncated cone-shaped base and a substantially partially spherical apex formed on the base, and that the multiple protrusions are provided on a side of the main body portion including the boundary between the base and the apex. Effect of the Invention

[0013] According to the present invention, it is possible to provide a magnet for magnetic therapy that, when attached to the skin of the human body, reduces the occurrence of pain and can exert a large magnetic force at multiple locations. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, a magnetic therapy magnet 1 according to one embodiment of the present invention (hereinafter, simply referred to as "magnet 1") will be described with reference to the attached drawings. However, the following embodiment is merely an example, and the magnetic therapy magnet of the present invention is not limited to the following example. In the following description, as shown in FIG. 3, a direction that is approximately perpendicular to the bottom surface 2a of the magnet 1 and connects the bottom surface 2a and the top end 2b of the magnet 1 is referred to as a height direction HD, and a direction approximately perpendicular to the height direction HD is referred to as a width direction WD. In addition, in the height direction HD, the direction from the bottom surface 2a to the top end 2b is represented by an expression "up" or a similar expression, and the direction from the top end 2b to the bottom surface 2a is represented by an expression "down" or a similar expression. In addition, when the term "height" is used for a certain part, unless otherwise specified, the term "height" means the height of that part from the bottom surface 2a in the height direction HD.

[0016] The magnet 1 of this embodiment is used by being attached so as to come into direct or indirect contact with the skin S of the human body, as shown in Fig. 5. When the magnet 1 is attached to the skin S of the human body, a magnetic field is applied to the body at the part where the magnet 1 is attached, thereby providing magnetic therapeutic effects such as promoting blood circulation in and around the body and promoting metabolism. The position of the skin S to which the magnet 1 is attached is not particularly limited as long as it is a position where the magnetic therapeutic effect can be exerted, and may be any position of the human body, such as the shoulder, arm, neck, waist, or leg.

[0017] The magnet 1 can constitute a magnetic therapy device together with an adhesive sheet AS attached to the bottom surface 2a of the main body 2 of the magnet 1, as shown in Fig. 5, for example. The magnet 1 is attached to the skin S of the human body so that the top end 2b side of the magnet 1 directly contacts the skin S by attaching a portion of the adhesive sheet AS attached to the bottom surface 2a of the magnet 1 outwardly in the width direction WD from the magnet 1 to the skin S. However, the magnet 1 only needs to be attached to the skin S of the human body, and may be attached so as to indirectly contact the skin S of the human body via an adhesive sheet interposed between the magnet 1 and the skin S of the human body, or may be attached by a band or the like, without being limited to attachment.

[0018] The magnet 1 has two magnetic poles (N pole, S pole) and generates magnetic field lines that can exert a magnetic therapeutic effect on the human body. In this embodiment, the magnet 1 has a magnetic pole direction along the height direction HD. Since the magnet 1 has a magnetic pole direction along the height direction HD, when the magnet 1 is attached so that the top end 2b side faces the surface of the skin S of the human body and used, the magnet 1 is arranged so that the magnetic pole direction faces in a direction approximately perpendicular to the surface of the skin S of the human body. Since the magnetic pole direction of the magnet 1 extends in a direction approximately perpendicular to the surface of the skin S of the human body in this way, the magnetic field strength in the direction approximately perpendicular to the surface of the skin S is larger than when the magnetic pole direction extends parallel to the surface of the skin S, and the magnetism can be applied from the surface of the skin S to deeper inside the body. However, the magnet 1 only needs to generate magnetic field lines that can exert a magnetic therapeutic effect on the human body, and the magnetic pole direction may be inclined from the height direction HD.

[0019] As shown in Figs. 1 to 3, the magnet 1 includes a main body 2 formed in a substantially conical shape and a plurality of protrusions 3 formed on the side surface of the main body 2. In this embodiment, the main body 2 and the protrusions 3 are formed as an integral body, but they may be formed as separate bodies and joined together. The size of the magnet 1 is not particularly limited as long as it is easy to attach to the skin S of the human body, but for example, the length in the height direction HD can be 1 mm or more and 3 mm or less, preferably 1.5 mm or more and 2.5 mm or less, more preferably 1.8 mm or more and 2.3 mm or less, and the length in the width direction WD can be 4 mm or more and 20 mm or less, preferably 6 mm or more and 12 mm or less, more preferably 7 mm or more and 9 mm or less.

[0020] As shown in FIG. 3, the main body 2 has a bottom surface 2a, an apex 2b (the highest part of the main body 2) spaced from the bottom surface 2a in a direction (height direction HD) substantially perpendicular to the bottom surface 2a, and a side surface 2c extending between the outer periphery of the bottom surface 2a and the apex 2b, and is formed in a substantially conical shape with a diameter decreasing from the bottom surface 2a toward the apex 2b. In this embodiment, as shown in FIG. 1 and FIG. 3, the bottom surface 2a is formed in a substantially circular shape, and the apex 2b is disposed on a central axis X that passes through the approximate center of the bottom surface 2a and extends substantially perpendicular to the bottom surface 2a. As a result, the main body 2 is formed in a substantially right circular cone shape. However, the main body 2 is not limited to a substantially right circular cone shape, and may be formed, for example, in a substantially oblique cone shape with the apex offset from the central axis, or in a substantially elliptical cone shape with a bottom surface having a substantially elliptical shape. The fact that the main body 2 is formed in a substantially conical shape means that the diameter of the main body 2 is at least partially tapered in a substantially linear manner from the bottom surface 2a toward the apex 2b. In other words, it means that at least a part of the edge of the side surface 2c of the main body 2 is formed in a substantially straight line in a side view of the main body 2 (see FIG. 3). The main body 2 is formed so that at least a part of the edge of the side surface 2c of the main body 2 is substantially straight in a side view of the main body 2, and as shown in FIG. 3, the edge of the side surface 2c of the main body 2 near the apex 2b may be formed in a curved line.

[0021] The magnet 1 has a body portion 2 formed in a substantially conical shape, i.e., the body portion 2 at least partially tapers in a substantially linear manner from the bottom surface 2a toward the apex end 2b, so that even if the magnet 1 moves in the width direction WD with the apex end 2b side of the body portion 2 pressed against the skin S of the human body and attached as shown in Fig. 4, the skin S of the human body can slide relatively easily along the side surface 2c of the body portion 2, thereby suppressing pain caused by the magnet 1 coming into contact with the skin S. Furthermore, the magnet 1 has a body portion 2 formed in a substantially conical shape, so that the magnetic field lines can be concentrated near the apex end 2b of the body portion 2, and the magnetic force near the apex end 2b can be increased.

[0022] In this embodiment, as shown in Fig. 3, the bottom surface 2a of the main body 2 is formed in a substantially flat shape. This makes it difficult for the adhesive sheet AS to peel off from the bottom surface 2a when the adhesive sheet AS is attached to the bottom surface 2a. However, the main body 2 only needs to be formed in a substantially conical shape, and the bottom surface 2a may be curved.

[0023] The main body 2 may be formed in a substantially conical shape and is not particularly limited, but in this embodiment, as shown in Figures 1 to 3, it includes a substantially truncated conical base 21 and a substantially partially spherical apex 22 formed on the base 21. In this embodiment, the base 21 and the apex 22 are stacked vertically and integrally formed so that their respective side surfaces are flush and continuous, but they may be formed separately and joined to each other.

[0024] As shown in Figs. 1 and 3, the base 21 has an upper surface (not marked) located at the boundary A between the base 21 and the top 22, and a bottom surface 2a, and has a shape in which the diameter is reduced (whole or part) from the bottom surface 2a to the upper surface in an approximately linear manner. Therefore, the side surface of the base 21 has an end edge formed in a substantially straight line (whole or part) in a side view (see Fig. 3), and is inclined with respect to the height direction HD. The side surface of the base 21 may be inclined with respect to the height direction HD, and the inclination angle is not particularly limited. However, the inclination angle of the base 21 with respect to the height direction HD (first inclination angle θ1, see Fig. 4) is preferably 45° or more, more preferably 55° or more, and even more preferably 60° or more, from the viewpoint of suppressing pain caused by the magnet 1 contacting the skin S. Furthermore, from the viewpoint of concentrating the magnetic lines of force near the apex end 2b of the main body 2 and increasing the magnetic force near the apex end 2b, the first inclination angle θ1 is preferably 80° or less, more preferably 70° or less, and even more preferably 65° or less.

[0025] The base 21 may be formed in a substantially truncated cone shape, and is not particularly limited thereto. For example, the base 21 may have a shape that decreases in diameter from the bottom surface 2a to the upper surface in a substantially linear manner, or may have an upper base 21a and a lower base 21b stacked in the height direction HD as shown in Figs. 1 to 3. The upper base 21a and the lower base 21b are both formed in a substantially truncated cone shape, and are integrally formed so that their side surfaces are flush and continuous. As shown in Fig. 4, the upper base 21a has a side surface that is inclined at a first inclination angle θ1 with respect to the height direction HD, and the lower base 21b has a side surface that is inclined at an inclination angle (second inclination angle θ2) smaller than the first inclination angle θ1 with respect to the height direction HD. By providing the lower base 21b having a side surface with a small inclination angle below the upper base 21a, when multiple magnets 1 are transported on the production line in the manufacturing process of the magnet 1, one magnet is prevented from riding up along the side surface of another magnet, so that clogging of the production line can be prevented. Also, by providing the lower base 21b having a side surface with a small inclination angle below the upper base 21a, the length of the height direction HD of the base 21 can be increased while suppressing the size of the width direction WD of the bottom surface 2a of the magnet 1, so that the magnetic force of the magnet 1 can be increased. Note that, as shown in Figures 3 and 4, the side surface of the base 21 at the boundary B between the upper base 21a and the lower base 21b may be chamfered to form a gentle side surface.

[0026] The inclination angle (second inclination angle θ2, see FIG. 4) of the lower base 21b with respect to the height direction HD may be smaller than the first inclination angle θ1, and is not particularly limited, but is set, for example, in the range of 5° or more and 15° or less. The sizes of the upper base 21a and the lower base 21b are not particularly limited, but from the viewpoint of suppressing pain caused by the magnet 1 contacting the skin S, the length of the upper base 21a in the height direction HD is preferably 2.5 times or more, more preferably 3.0 times or more, and even more preferably 3.5 times or more than the length of the lower base 21b in the height direction HD. From the viewpoint of further suppressing clogging of the production line and obtaining a larger magnetic force with a smaller width, the length of the upper base 21a in the height direction HD is preferably 5.5 times or less, more preferably 5.0 times or less, and even more preferably 4.5 times or less than the length of the lower base 21b in the height direction HD.

[0027] As shown in Fig. 3, the apex 22 has an apex end 2b and a lower surface (not marked) located at the boundary A between the base 21 and the apex 22, and has a shape with a diameter that tapers from the lower surface toward the apex 2b. Unlike the base 21, the apex 22 is formed in a substantially partial sphere having a predetermined radius of curvature (first radius of curvature), and the side surface is formed with a curved surface. By forming the side surface of the apex 22 with a curved surface, it is possible to further reduce pain caused by the magnet 1 coming into contact when the apex 22 is attached by pressing it against the skin S of the human body.

[0028] The radius of curvature (first radius of curvature) of the apex 22 is not particularly limited, but is preferably larger than the radius of curvature (second radius of curvature) of the protrusion 3, as described in detail below. For example, from the viewpoint of suppressing pain caused by the apex 22 contacting the skin S of the human body, the first radius of curvature is preferably 2.0 times or more than the second radius of curvature, more preferably 2.5 times or more, and even more preferably 3.0 times or more. Also, from the viewpoint of concentrating the magnetic field lines near the apex end 2b and increasing the magnetic force near the apex end 2b, the first radius of curvature is preferably 5.0 times or less than the second radius of curvature, more preferably 4.5 times or less, and even more preferably 4.0 times or less. For example, from the viewpoint of suppressing pain, the first radius of curvature is preferably 2.5 mm or more, more preferably 3.0 mm or more, and even more preferably 3.3 mm or more. Furthermore, the first radius of curvature is, for example, preferably equal to or less than 4.5 mm, more preferably equal to or less than 4.0 mm, and even more preferably equal to or less than 3.7 mm, from the viewpoint of increasing the magnetic force.

[0029] Furthermore, the size of the top 22 is not particularly limited, but from the viewpoint of suppressing pain caused by the magnet 1 abutting the skin S, the length of the top 22 in the height direction HD is preferably 0.05 times or more, more preferably 0.10 times or more, and even more preferably 0.15 times or more, the length of the base 21 in the height direction HD. From the viewpoint of concentrating the magnetic field lines near the apex end 2b and increasing the magnetic force near the apex end 2b, the length of the top 22 in the height direction HD is preferably 0.40 times or less, more preferably 0.35 times or less, and even more preferably 0.30 times or less, the length of the base 21 in the height direction HD.

[0030] As shown in FIG. 3, the protrusion 3 is provided on the side surface 2c of the main body 2 so as to protrude upward from the side surface 2c of the main body 2 in the height direction HD. By providing the protrusion 3 protruding upward from the side surface 2c of the main body 2, the height (thickness) of the part where the protrusion 3 is provided is increased, and magnetic lines of force are concentrated at the protrusion 3, so that the magnetic force at the protrusion 3 is increased. By forming a plurality of such protrusions 3 at intervals from each other, the magnet 1 can exert a large magnetic force at a plurality of locations. This makes it possible to easily position a portion of the human body where a large magnetic force is generated at a portion where a magnetic therapeutic effect is desired. In this embodiment, three protrusions 3 are provided, but as long as they can be provided at intervals from each other, the number of protrusions 3 may be two or four or more.

[0031] The protrusion 3 may be provided so as to protrude upward from the side surface 2c of the main body 2, and the size of the protrusion 3 is not particularly limited. In this embodiment, the multiple protrusions 3 are formed so that the heights of the apex ends 3a (the parts located at the highest positions among the protrusions 3) of the multiple protrusions 3 from the bottom surface 2a are approximately the same. This allows the magnetic forces of the multiple protrusions 3 to be approximately the same, so that the magnetic forces of the multiple protrusions 3 can be approximately the same regardless of the part of the human body to which each protrusion 3 is positioned. Furthermore, in this embodiment, the multiple protrusions 3 are formed so that the apex ends 3a of the multiple protrusions 3 are approximately the same height as the apex end 2b of the main body 2. This causes the magnitude of the magnetic force at the apex end 2b of the main body 2 to approach or be approximately the same as the magnitude of the magnetic force at the apex end 3a of the multiple protrusions 3, further increasing the number of places where a large magnetic force is exerted. Furthermore, by increasing the number of areas at approximately the same height, the number of areas that come into contact with the skin S when the magnet 1 presses against the skin S of the human body increases, so that the pressing force of the magnet 1 can be distributed to multiple areas, further reducing pain to the skin S caused by the magnet 1 coming into contact with it.

[0032] The projection 3 may be provided so as to protrude upward from the side surface of the main body 2, and the shape of the projection 3 is not particularly limited. In this embodiment, the projection 3 is formed in a substantially partial sphere having a predetermined radius of curvature (second radius of curvature) as shown in Figs. 1 to 3. This makes it possible to suppress pain caused by the magnet 1 coming into contact when the projection 3 is pressed against the skin S of the human body. In this embodiment, the projection 3 is formed so that the radius of curvature (second radius of curvature) of the projection 3 is smaller than the radius of curvature (first radius of curvature) of the apex 22 of the main body 2. By making the radius of curvature of the projection 3 smaller than the radius of curvature of the apex 22, a larger magnetic force can be generated in the projection 3. From the viewpoint of increasing the magnetic force in the projection 3, the radius of curvature of the projection 3 is preferably 0.50 times or less, more preferably 0.40 times or less, and even more preferably 0.33 times or less, of the radius of curvature of the apex 22. Moreover, from the viewpoint of suppressing pain caused by the protrusion 3 contacting the skin S of the human body, the radius of curvature of the protrusion 3 is preferably 0.20 times or more, more preferably 0.22 times or more, and even more preferably 0.25 times or more of the second radius of curvature of the apex 22. From the viewpoint of increasing the magnetic force, the second radius of curvature is preferably 2.0 mm or less, preferably 1.5 mm or less, and even more preferably 1.2 mm or less. From the viewpoint of suppressing pain, the second radius of curvature is preferably 0.5 mm or more, more preferably 0.7 mm or more, and even more preferably 0.9 mm or more.

[0033] The protrusions 3 may be provided so as to protrude upward from the side surface of the main body 2, and the position at which they are provided is not particularly limited. In this embodiment, the multiple protrusions 3 are provided on the side surface above the intermediate height of the main body 2, as shown in FIG. 3. This allows the height of the apex 3a of the protrusions 3 to be increased without increasing the height of the protrusions 3 themselves, so that a large magnetic force can be applied to the human body while suppressing pain caused by the protrusions 3 abutting against the skin S of the human body. From the viewpoint of suppressing pain caused by the protrusions 3 abutting against the skin S of the human body, the height at which the protrusions 3 are provided (the height of the position at which the axis extending along the height direction HD passing through the apex 3a of the protrusions 3 intersects with the side surface of the main body 2) is preferably 0.60 times or more, more preferably 0.70 times or more, and even more preferably 0.80 times or more, of the height of the main body 2. Furthermore, from the viewpoint of widely dispersing the multiple protrusions 3 within a plane including the width direction WD, the height at which the protrusions 3 are provided is preferably 0.95 times or less, more preferably 0.90 times or less, and even more preferably 0.85 times or less, of the height of the main body portion 2.

[0034] In this embodiment, as shown in Figures 1 to 3, the protrusion 3 is provided on the side surface of the main body 2 including the boundary A between the base 21 and the top 22. By providing the protrusion 3 so as to straddle the side surfaces of the base 21 and the top 22 which have different inclinations, even if the protrusion 3 receives a force from various directions such as the height direction HD and the width direction WD of the magnet 1, the protrusion 3 can resist the force with the slopes of the base 21 and the top 22 which have different inclinations, and therefore damage to the protrusion 3 is suppressed. However, the protrusion 3 may be provided only on the side surface of the base 21 or only on the side surface of the top 22.

[0035] The magnet 1 may be made of any material that can generate magnetic lines of force that can have a magnetic therapeutic effect on the human body. The magnet 1 may be made of, for example, neodymium, ferrite, samarium cobalt, or a bonded magnet made by mixing these with resin. Among these, the magnet 1 preferably contains a ferrite bonded magnet from the viewpoint of moldability and stability. By using a ferrite bonded magnet as a constituent material, the magnet 1 can be easily molded by mold molding (e.g., injection molding). The magnetic force of the magnet 1 is set to be 200 mT or less on the skin surface, which is the certification standard of the Ministry of Health, Labor and Welfare, and is set to be, for example, 120 to 140 mT near the top end 3a of the protrusion 3.
