Description

Technical Field

[0001] This invention relates to a magnetic therapy device. Background Technology

[0002] Traditionally, magnetic therapy devices, such as those disclosed in Patent Documents 1 and 2, have been used to apply magnetic therapy to desired areas from the back of the head to the base of the neck. The magnetic therapy device in Patent Document 1 is mounted on eyeglasses, while the magnetic therapy device in Patent Document 2 is worn around the neck.

[0003] [Existing Technical Documents] [Patent Literature] [Patent Document 1] Japanese Patent Application Publication No. 2021-186382 [Patent Document 2] Japanese Patent Application Publication No. 2022-26091 Summary of the Invention [The problem this invention aims to solve] Because the magnetic therapy device in Patent Document 1 is of a fixed size, it may be difficult to position the magnetic object close to the desired area depending on the body shape (e.g., the shape and size of the head or neck). Furthermore, the magnetic therapy device in Patent Document 1 requires the wearing of glasses to be worn. In contrast, the magnetic therapy device in Patent Document 2 is simply hung around the neck without being fixed in place, so the position of the magnetic object may shift during use.

[0004] The present invention was made in view of the above-mentioned problems, and its object is to provide a magnetic therapy device that can bring a magnetic body close to a desired part of the human body and can suppress the displacement of the magnetic body during use.

[0005] [Problem-solving methods] The magnetic therapy device of the present invention includes: a pair of ear hooks; a magnetic body; and a holding part, the holding part extending between the pair of ear hooks, connected to the pair of ear hooks, and holding the magnetic body, wherein the holding part is configured to adjust the length of the holding part along the length direction in which the holding part extends.

[0006] [Invention Effects] The present invention provides a magnetic therapy device that can bring a magnetic object close to a desired part of the human body and can suppress the displacement of the magnetic object during use. Attached Figure Description

[0019] The following description, in conjunction with the accompanying drawings, describes a magnetic therapy device according to an embodiment of the present invention. However, the following embodiments are merely examples, and the magnetic therapy device of the present invention is not limited to these examples. It should be noted that in this specification, the directions of human body parts can be described as follows: in the height direction of the human body, the direction towards the head is designated as "up," and the direction towards the feet as "down"; in the front-back direction of the human body, the ventral side is designated as "front," and the back side as "back"; in the left-right direction of the human body, when looking forward from behind, the right side is designated as "right," and the left side as "left," or similar expressions can be used. Furthermore, the direction of the magnetic therapy device can also be described corresponding to the direction of the magnetic therapy device relative to the human body part during use.

[0020] The magnetic therapy device 1 in this embodiment (such as...) Figure 1(As shown) is used by hanging it on the ear E of a human body. By hanging it on the ear E of a human body, the magnetic body 3 can be positioned near the desired area (hereinafter, sometimes simply referred to as the "desired area") from the back of the head H to the root of the neck N, and a magnetic field is applied to the desired area and its surroundings, thereby producing magnetic therapy effects such as promoting blood circulation and improving metabolism.

[0021] Magnetic therapy device 1 (such as Figure 2 and Figure 3 The magnetic therapy device 1 (shown) includes a pair of ear loops 2, a magnetic body 3, and a holding part 4 for holding the magnetic body 3. The magnetic therapy device 1 is configured such that by hanging the ear loops 2 on the human ear E, the magnetic body 3 can be positioned close to the desired location. By hanging the magnetic therapy device 1 on the human ear E, the position of the magnetic body 3 relative to the human ear E can be maintained relatively stably, thus suppressing positional displacement of the magnetic body 3 during use. Furthermore, as described in detail below, the holding part 4 is configured such that its length can be adjusted along the length direction L of its extension. By adjusting the length of the holding part 4 according to the human body's physique (the shape and size of the head H or neck N), the magnetic body 3 can be positioned close to (preferably in close contact with) the desired location on the human body without being affected by the human body's physique. A pair of ear loops 2, 2 (such as Figure 1 (As shown) Hanging on the human ear E, it is held relative to the human ear E by the holding part 4, and the magnetic body part 3 is held by the holding part 4. One of the pair of ear hook parts 2, 2 (as shown) Figure 2 and Figure 3 As shown, the ear hook 2 is installed at one end of the holding part 4 in the length direction L, and the other ear hook 2 of the pair of ear hook parts 2, 2 is installed at the other end of the holding part 4 in the length direction L. In this embodiment, the ear hook 2 (as shown) is installed at one end of the holding part 4 in the length direction L. Figure 10 The ear hook 2 is detachably mounted relative to the retaining part 4 (see solid lines and double-dotted lines in the figure). Therefore, by removing the ear hook 2 from the retaining part 4, the magnetic therapy device 1 can use only the main body parts (magnetic body 3 and retaining part 4) excluding the ear hook 2. Furthermore, the magnetic therapy device 1 can be interchanged with ear hooks 2 of different lengths in the vertical direction, and the placement height of the magnetic body 3 can be adjusted according to the desired location for applying magnetic therapy, such as the hairline of the head H or the base of the neck N. For this purpose, the magnetic therapy device 1 can have multiple ear hooks 2 of different lengths in the vertical direction. Moreover, the ear hook 2 is not limited to this embodiment and can also be fixed relative to the retaining part 4.

[0022] Ear loop 2 (e.g.) Figure 6 and Figure 12 As shown, it can be rotatably mounted relative to the retaining part 4 with a rotation axis X extending along the length direction L as the center. In this embodiment, as... Figure 10 and Figure 11 As shown, the ear hook side connecting portion 231 of the ear hook portion 2 (described later) and the retaining portion side connecting portion 413 of the retaining portion 4 (described later) are configured to rotate relative to each other about the rotation axis X when they are connected to each other. The ear hook portion 2 can rotate relative to the retaining portion 4 about the rotation axis X, for example, adjusting the spacing between a pair of ear hook portions 2, 2 (the spacing between the connecting portions 21, 21 (described later)) according to the size of the human head H, or, for example, by changing the ear hook portion 2 from its use state ( Figure 6 Folding to storage state (in its current state) Figure 12 (in its current state), the magnetic therapy device 1 can be transformed into a compact shape.

[0023] The magnetic therapy device 1 may include a positioning mechanism for positioning the ear hook portion 2 relative to the holding portion 4 at a predetermined rotational position. The positioning mechanism is configured to position the ear hook portion 2 at a first rotational position relative to a plane substantially perpendicular to a plane including the length direction L. Figure 6 and Figure 10 The position of the ear loop 2 within the plane containing the length direction L; and the second rotational position of the ear loop 2 within the plane containing the length direction L. Figure 11 and Figure 12 (Position). Thus, since the ear loop 2 can be easily positioned in a first rotational position for use and a second rotational position for storage, preparation for use and storage can be done quickly. The positioning mechanism will be described in detail below. Ear loop 2 (e.g.) Figure 1 As shown, the ear hook 2 is configured such that when it is hung on the human ear E, the magnetic part 3 can be positioned close to a desired location on the human body. Its structure and shape are not particularly limited as long as the magnetic part 3 can be positioned close to a desired location on the human body when the ear hook 2 is hung on the human ear E. In this embodiment, the ear hook 2 (as shown) is configured such that when it is hung on the human ear E, the magnetic part 3 can be positioned close to a desired location on the human body. Figure 2 , Figure 3 and Figure 5 As shown, the ear loop 2 has a connecting portion 21 that engages with the human ear E, a mounting portion 23 that is mounted on the retaining portion 4, and an extension portion 22 that extends between the connecting portion 21 and the mounting portion 23. In this embodiment, the ear loop 2 is integrally formed with the connecting portion 21, the extension portion 22, and the mounting portion 23, but they can also be formed as separate components and connected to each other.

[0024] The joint 21 is configured to engage with the human ear E and head H in the left-right, front-back, and downward directions when attached to the ear E. More specifically, the joint 21 (e.g.) Figure 5As shown, the ear loop 21 is formed into an approximately semi-circular shape with an opening at the bottom and a protrusion at the top. The connecting portion 21 is essentially joined to the human ear E and head H in the left-right direction, near the two ends in the front-back direction, and near the center in the front-back direction, in the downward direction. Therefore, the movement of the ear loop 2 relative to the human body in the left-right, front-back, and downward directions is suppressed. Thus, when the magnetic therapy device 1 is used on the human ear E, it can stably maintain the position of the holding portion 4, thereby stably maintaining the position of the magnetic body portion 3.

[0025] Extension 22 (e.g.) Figure 5 The extension 22 is connected to the rear end of the connecting part 21 at one end (top) and to the mounting part 23 at the other end (bottom). The extension 22 is configured to slope forward (from right to left in the figure) from one end (top) to the other end (bottom). Therefore, compared to the case where the extension 22 extends downward without slope, the center of gravity of the magnetic therapy device 1 is located in the front (left in the figure), thus suppressing the magnetic therapy device 1 from tilting backward (right in the figure) during use. In this embodiment, the extension 22 is sloped such that the other end (bottom) of the extension 22 is located near the front end of the connecting part 21 in the front-rear direction. However, the slope angle of the extension 22 is not particularly limited; it can be sloped opposite to the illustrated example, or it can extend straight downward without slope in any direction. Furthermore, the length of the extension 22 in the extension direction is not particularly limited; it can be set so that the magnetic part 3 can be positioned in the desired vertical direction.

[0026] Installation section 23 (e.g.) Figure 5 As shown, the end of the mounting portion 23 is connected at one end (front) to the other end (lower) of the extension 22, and is mounted to the retaining portion 4 at the other end (rear). In this embodiment, the mounting portion 23 (as shown) Figure 10 (As shown) includes an ear loop side connecting portion 231 that connects to the retaining portion side connecting portion 413 of the retaining portion 4 described later. The ear loop side connecting portion 231 and the retaining portion side connecting portion 413 are configured to be detachable from each other. The mounting portion 23 is mounted to the retaining portion 4 via the ear loop side connecting portion 231 and the retaining portion side connecting portion 413, and is detached from the retaining portion 4 via the ear loop side connecting portion 231. Details of the connection mechanism between the ear loop side connecting portion 231 and the retaining portion side connecting portion 413 will be described later. Furthermore, despite the above description, the ear loop side connecting portion 231 and the retaining portion side connecting portion 413 may also be configured to be non-detachable from each other.

[0027] like Figure 10As shown, the mounting portion 23 is also provided with a recess 232 recessed from its other end (rear). In the illustrated example, two recesses 232 are provided on both sides of the ear loop side connecting portion 231 in the vertical direction. The recesses 232 are provided when the ear loop portion 2 is in the first rotational position (use position). Figure 6 and Figure 10 The recess 232 is configured to engage with the protrusion 415 of the retaining part 4 (described later) at the position described above, and is shaped and sized to correspond to the protrusion 415. Thus, the recess 232 is configured to engage with the protrusion 415, and together with the protrusion 415, constitutes the positioning mechanism described above. Therefore, the first rotational position of the ear loop 2 becomes a quasi-stable position, and the ear loop 2 can be easily positioned relative to the retaining part 4 at the first rotational position. The ear hook portion 2 preferably possesses rigidity that prevents deformation due to the weight of the magnetic body portion 3 and the holding portion 4 when the magnetic therapy device 1 is resting on the human ear E. This further suppresses positional displacement of the magnetic body portion 3 during use. Furthermore, the ear hook portion 2 preferably possesses flexibility that allows it to deform according to the size and shape of the human head H. Therefore, when the ear hook portion 2 is worn on the human ear E, it can easily deform according to the size and shape of the human head H, thus allowing it to be easily worn on the human ear E. The material constituting the ear hook portion 2 is not particularly limited, and can be thermosetting elastomers such as silicone rubber, polyurethane rubber (U), isoprene rubber (IR), styrene-butadiene rubber (SBR), natural rubber, ethylene propylene diene monomer (EPDM), and nitrile rubber (NBR), or thermoplastic elastomers such as polyurethane-based, ester-based, styrene-based, olefin-based, butadiene-based, and fluoropolymers, or composites thereof. Among these materials, silicone rubber is particularly preferred due to its excellent biocompatibility, heat resistance, and cold resistance.

[0028] The magnetic body 3 generates a magnetic field, specifically a magnetic field capable of applying a magnetic therapy effect to desired areas of the human body. The structure of the magnetic body 3 is not particularly limited, as long as it is configured to generate a magnetic field. In this embodiment, the magnetic body 3 (e.g., Figure 3 and Figure 4 The device (shown) includes one or more (six in the illustrated example) magnetic bodies 31 and a magnetic body holding part 32 for holding the magnetic bodies 31. The magnetic body holding part 32 holds a plurality of (six in the illustrated example) magnetic bodies 31 arranged at intervals along the length direction L of the holding part 4. This allows for the application of magnetic therapy effects to multiple parts of the human body. Furthermore, the magnetic bodies 31 are disposed on the front side of the magnetic body holding part 32, i.e., the side facing the human body when the magnetic therapy device 1 is hung on the ear E of the human body. This allows for the application of a stronger magnetic field to the human body, resulting in a higher magnetic therapy effect. Moreover, the magnetic body part is not limited to this embodiment; for example, it may be composed solely of magnetic bodies.

[0029] The magnetic body 31 generates a magnetic field, specifically a magnetic field capable of applying a magnetic therapy effect to desired areas of the human body. The magnetic body 31 is not particularly limited; in this embodiment, for example… Figure 3 and Figure 4 As shown, the magnetic body 31 is formed into an approximately disc-shaped structure, with its thickness direction facing the human body when the magnetic therapy device 1 is hung on the ear E of the human body. The magnetic body 31, for example, has magnetic poles by being magnetized along its thickness direction, thereby enabling the application of a magnetic field deep into the human body. However, as long as the magnetic body 31 can apply a magnetic field to the desired area of ​​the human body, its shape is not particularly limited; for example, it can also be in powder form. Furthermore, the material constituting the magnetic body 31 is not particularly limited; ferrite magnets, neodymium magnets, samarium cobalt magnets, etc., can be used. The output level of the magnetic body 31 is not particularly limited; for example, it can be set to meet the Ministry of Health, Labour and Welfare certification standard of 200 mT or less on the skin surface.

[0030] The magnetic body holding part 32 is only required to be held by the holding part 4 and to hold the magnetic body 31; its configuration is not particularly limited. In this embodiment, the magnetic body holding part 32 (such as...) Figures 3 to 5 As shown, when held by the holding part 4, the magnetic body holding part 32 has a shape corresponding to the shape of the holding part 4. More specifically, when held by the holding part 4, the magnetic body holding part 32 bends rearward, forming an approximately plate-like shape extending along the length direction L of the holding part 4. In particular, the magnetic body holding part 32 has a cutout 321 extending in a direction substantially perpendicular to the length direction L of the holding part 4 (vertical direction) between the magnetic bodies 31, 31 on its front side. As a result, the magnetic body holding part 32 can easily bend rearward when held by the holding part 4. In this embodiment, when not held by the holding part 4, the magnetic body holding part 32 has an initial shape different from the shape when held by the holding part 4, for example, an approximately straight shape. The magnetic body holding part 32, when held by the holding part 4, deforms from its initial shape into a shape corresponding to the shape of the holding part 4. In particular, as described above, by providing a cutout 321 on the magnetic body holding part 32, the magnetic body holding part 32 can be easily bent to the rearward side, and can be easily installed onto the holding part 4 which is formed to protrude to the rearward side.

[0031] The holding part 32 is only required to be held by the holding part 4, and its holding shape is not particularly limited. In this embodiment, the magnetic body holding part 32 (e.g., Figures 2 to 5The magnetic material retaining part 32 (shown) has a through hole 322 extending along its length L for insertion of a retaining part 4 (retaining body 42 described later). The magnetic material retaining part 32 is configured to be held by inserting the retaining part 4 into the through hole 322. As described above, the magnetic material retaining part 32 deforms from its initial shape into a shape corresponding to the shape of the retaining part 4 when inserted into the through hole 322 by the retaining part 4. At this time, the magnetic material retaining part 32 deforms due to the pressure exerted by the retaining part 4 on the peripheral wall of the through hole 322, but the pressure applied by the retaining part 4 on the peripheral wall of the through hole 322 increases the sliding resistance of the magnetic material retaining part 32 relative to the retaining part 4. Therefore, the position of the magnetic material retaining part 32 relative to the retaining part 4 becomes more stable, thereby making the position of the magnetic material part 3 more stable.

[0032] The magnetic holding part 32 preferably has flexibility, allowing it to deform from its initial shape to a shape corresponding to that of the holding part 4, and to deform according to the shape and size of the head H and neck N when the magnetic therapy device 1 is hung on the human ear E. The material constituting the magnetic holding part 32 is not particularly limited, and can be, for example, thermosetting elastomers such as silicone rubber, polyurethane rubber (U), isoprene rubber (IR), styrene-butadiene rubber (SBR), natural rubber, ethylene propylene diene monomer (EPDM), and nitrile rubber (NBR), or thermoplastic elastomers such as polyurethane-based, ester-based, styrene-based, olefin-based, butadiene-based, and fluoropolymer-based elastomers, or composites thereof. Among these materials, silicone rubber is particularly preferred due to its excellent biocompatibility, heat resistance, and cold resistance.

[0033] Retaining part 4 (e.g.) Figures 2 to 4 (As shown) Extends between a pair of ear hook portions 2, 2, connects to the pair of ear hook portions 2, 2, and holds the magnetic body portion 3. More specifically, the holding portion 4 is connected to one ear hook portion 2 of the pair of ear hook portions 2, 2 at one end in the length direction L of the holding portion 4, and to the other ear hook portion 2 of the pair of ear hook portions 2, 2 at the other end in the length direction L of the holding portion 4. The shape of the holding portion 4 is not particularly limited as long as it can hold the magnetic body portion 3 in a position close to the desired part of the human body when the magnetic therapy device 1 is hung on the human ear E. However, the holding portion 4 preferably has a shape along the back of the human head H or neck N. In this embodiment, the holding portion 4 (as shown) Figure 2 , Figure 3 and Figure 6 As shown, it is formed into an approximately semi-circular shape with an opening at the front and a protrusion at the rear. This makes it easy to arrange the retaining part 4 around the human head H or neck N, and easy to position the magnetic part 3 at the desired location.

[0034] Retaining part 4 (e.g.) Figure 7As shown, the length of the retaining part 4 can be adjusted along the length direction L of the retaining part 4 (refer to the positions of the solid line and the double-dotted line in the diagram). Thus, the length of the retaining part 4, that is, the length between the pair of ear loops 2, 2, can be adjusted according to the body shape of the human body (the shape and size of the head H or the neck N), so that the magnetic part 3 can be positioned close to (preferably in close contact) at any desired location from the back of the human head H to the root of the neck N, regardless of the body shape of the human body.

[0035] The structure is not particularly limited as long as the holding part 4 can be adjusted in length direction L along the holding part 4. In this embodiment, the holding part 4 (e.g. Figures 2 to 6 (As shown) It includes: a pair of connecting portions 41, 41 connected to each of the pair of ear loop portions 2, 2; and a retaining body 42 extending between the pair of connecting portions 41, 41, connected to the pair of connecting portions 41, 41, and retaining the magnetic body portion 3. The retaining body 42 is configured to be movable along the length direction L relative to either or both of the pair of connecting portions 41, 41. By moving the retaining body 42 relative to the connecting portion 41 along the length direction L, the length between the pair of connecting portions 41, 41 can be adjusted, thereby adjusting the length of the retaining portion 4 along the length direction L. Furthermore, the retaining body may include two retaining bodies as described below, or it may include one or more retaining bodies. In the case of including multiple retaining bodies, the multiple retaining bodies may be connected to both of the pair of connecting portions, or one retaining body may be connected to either of the pair of connecting portions, and another retaining body may be connected to the other of the pair of connecting portions.

[0036] Retaining part 4 (e.g.) Figure 8 (As shown) can be configured to hold the magnetic body 3 in a manner that allows the position of the magnetic body 3 along the length direction L to be changed. Therefore, the position of the magnetic body 3 in the length direction L of the holding part 4 can be adjusted, thereby making it easy to position the magnetic body 3 at a desired location on the human body. In this embodiment, in order to allow the magnetic body 3 to change position along the length direction L, the holding part 4 (as shown) can be configured to hold the magnetic body 3 in a manner that allows the position of the magnetic body 3 to be changed. Figures 2 to 4 As shown, the magnetic body 3 is inserted into the through hole 322 of the magnetic body part 3, and is configured such that the magnetic body part 3 can slide along the length direction L of the holding part 4. More specifically, the holding body 42 of the holding part 4 is inserted into the through hole 322 of the magnetic body holding part 3, and the magnetic body holding part 32 of the magnetic body part 3 is configured to slide relative to the holding body 42 of the holding part 4 along the length direction L. However, in order to allow the magnetic body part 3 to change position along the length direction L, multiple mounting positions for the magnetic body part 3 can be provided along the length direction L of the holding part 4, for example. Furthermore, the magnetic body part 3 is not limited to this embodiment, and can also be fixed to the holding part 4 so that its position in the length direction L is fixed.

[0037] Retaining part 4 (e.g.) Figure 9 The magnetic body 3 (as shown) can be configured to change the angle of the magnetic body 3 relative to a direction substantially perpendicular to the plane containing the length direction L (in the figure, the inward and outward directions on the paper). In the illustrated example, the holding part 4 is configured to change the tilt angle of the magnetic body 3 in the plane containing the length direction L, in a direction substantially perpendicular to the length direction L (in the figure, the radial direction of the approximately semi-annular holding part 4). Therefore, the angle of the magnetic body 3 can be adjusted according to the shape of the human head H and neck N, thereby enabling more effective application of magnetic therapy to the desired areas of the human body. In this embodiment, in order to change the angle of the magnetic body 3, the holding part 4 (as shown) can be configured to change the angle of the magnetic body 3. Figures 2 to 4 (As shown) It includes: a pair of connecting portions 41, 41 connected to each of the pair of ear loop portions 2, 2; and a first retaining body 421 and a second retaining body 422 extending between the pair of connecting portions 41, 41, connected to the pair of connecting portions 41, 41, and retaining the magnetic body portion 3. Furthermore, the first retaining body 421 and the second retaining body 422 are independent of each other and can move along the length direction L relative to either or both of the pair of connecting portions 41, 41. Thus, as... Figure 9 As shown, by making the lengths of the two retainers 421 and 422 between a pair of connecting parts 41, 41 different, the angle of the magnetic body part 3 can be changed.

[0038] To illustrate more specifically the example shown in the figure, the retaining part 4, the first retaining body 421, and the second retaining body 422 (as shown in the figure) Figure 4 (As shown) When the lengths of the pair of connecting portions 41, 41 are substantially the same, they are positioned at intervals in a direction substantially perpendicular to the plane containing the length direction L (vertical direction). As will be described in detail below, a first retainer 421 is fixed to one of the pair of connecting portions 41, 41, and is movably connected to the other of the pair of connecting portions 41, 41 along the length direction L. A second retainer 422 is fixed to the other of the pair of connecting portions 41, 41, and is movably connected to one of the pair of connecting portions 41, 41 along the length direction L. Figure 9 As shown, by moving the first retainer 421 away from the other of the pair of connecting portions 41, 41, the length of the first retainer 421 between the pair of connecting portions 41, 41 increases. Conversely, by moving the second retainer 422 closer to one of the pair of connecting portions 41, 41, the length of the second retainer 422 between the pair of connecting portions 41, 41 decreases. Thus, as... Figure 9As shown, the first retainer 421 is longer than the second retainer 422 and is positioned further rearward (radially outward, lower side in the figure) than the second retainer 422. Consequently, the magnetic part 3, to which the first retainer 421 and the second retainer 422 are inserted, is tilted in the front-back direction (vertical direction in the figure). In this way, the retainer 4 can be configured to change the angle of the magnetic part 3. Furthermore, in this configuration, the length of the retainer 4 can be adjusted by adjusting the first retainer 421 and the second retainer 422 while keeping their lengths equal between the pair of connecting parts 41, 41.

[0039] The connecting part 41 of the retaining part 4 connects the retaining body 42 to the ear hook part 2. The connecting part 41, (as shown in the image) Figures 2 to 6 As shown, an ear loop 2 is mounted on one side (front side) of the ear loop 2, and a retainer 42 is connected to the other side (rear side) of the ear loop 2. A connecting part 41 (as shown) Figure 10 and Figure 11 (As shown) It has a connecting body 411 on which an ear hook 2 is installed and a retainer 42 is connected, and a covering part 412 covering the area around the connecting body 411.

[0040] Connector body 411 (e.g.) Figure 10 and Figure 11 As shown, the connecting body 411 has a retaining part side connecting part 413 at one end (front side) along its length direction L, which can be connected to the ear hook side connecting part 231 of the ear hook part 2. Additionally, the connecting body 411 has a receiving part 414 at its other end (rear side) along its length direction L. This receiving part 414 is used to movably connect a first retainer 421 and / or a second retainer 422 (the first retainer 421 is shown in the example) which serves as a retainer 42 along the length direction L. In this embodiment, one of the pair of connecting parts 41, 41 has a receiving part 414 for movably connecting the first retainer 421, and the other of the pair of connecting parts 41, 41 has a receiving part 414 for movably connecting the second retainer 422. However, it is also possible that one or the other of the pair of connecting parts 41, 41 has two receiving parts for both the first retainer 421 and the second retainer 422, while one or the other of the pair of connecting parts 41, 41 does not have a receiving part. Alternatively, both of the pair of connecting portions 41, 41 may be provided with two receiving portions for both the first retainer 421 and the second retainer 422.

[0041] The retaining-side connecting portion 413 provided on the connecting portion body 411 is configured to be detachable relative to the ear hook-side connecting portion 231 of the ear hook portion 2. In this embodiment, the retaining-side connecting portion 413 (such as...) Figure 10 and Figure 11(As shown) All have a solid large-diameter portion 413a and a small-diameter portion 413b smaller than the diameter of the large-diameter portion 413a. In contrast, the ear loop side connecting portions 231 all have a hollow large-diameter portion 231a and a small-diameter portion 231b smaller than the diameter of the large-diameter portion 231a, corresponding to the retaining portion side connecting portion 413. The large-diameter portion 413a and the small-diameter portion 413b of the retaining portion side connecting portion 413 are formed to correspond to the large-diameter portion 231a and the small-diameter portion 231b of the ear loop side connecting portion 231 in size and shape, respectively. By fitting the large-diameter portion 413a of the retaining portion side connecting portion 413 with the large-diameter portion 231a of the ear loop side connecting portion 231, the retaining portion side connecting portion 413 is connected to the ear loop side connecting portion 231. Figure 10 (Refer to solid lines). At this time, the small-diameter portion 231b of the ear hook side connecting portion 231 serves to prevent the large-diameter portion 413a of the retaining portion side connecting portion 413 from coming off. By pulling the retaining portion side connecting portion 413 away from the ear hook side connecting portion 231 with a force greater than a predetermined magnitude, the small-diameter portion 231b of the ear hook side connecting portion 231 expands, thereby pulling out the large-diameter portion 413a of the retaining portion side connecting portion 413, and the retaining portion side connecting portion 413 is disconnected from the ear hook side connecting portion 231. Figure 10 (Refer to the double-dotted line in the middle).

[0042] The receiving portion 414 provided in the connecting body 411 (e.g. Figure 10 and Figure 11 (As shown) is formed with an internal space capable of accommodating a first retainer 421 that can move along the length direction L. The receiving portion 414 has a large-diameter portion 414a and a small-diameter portion 414b that are alternately formed along the length direction L. The large-diameter portion 414a is formed to have a size corresponding to the outer diameter of the end member 421e provided at the front end of the first retainer 421, and the small-diameter portion 414b is formed to be smaller than the outer diameter of the end member 421e. The peripheral wall of the small-diameter portion 414b formed in the receiving portion 414 engages with the end member 421e of the first retainer 421 in the length direction L, and is configured to deform when the first retainer 421 moves relative to the receiving portion 414 with a force greater than a predetermined size in the length direction L. Thus, the end member 421e of the first retainer 421 can be quasi-stable maintained in the large-diameter portion 414a of the receiving portion 414. On the other hand, when the first retainer 421 moves along the length direction L with a force greater than a predetermined magnitude, the peripheral wall of the small-diameter portion 414b of the receiving portion 414 can be deformed, thereby moving to the adjacent large-diameter portion 414a. In this way, the first retainer 421 is connected in a manner that allows it to move along the length direction L relative to the connecting portion 41. It should be noted that the above description pertains to the combination of the receiving portion 414 and the first retainer 421, but this also applies to the combination of the receiving portion 414 and the second retainer 422, so its description will be omitted.

[0043] The connecting body 411 is preferably formed of, for example, a rigid material to suppress deformation when the ear loop 2 is installed or removed, thereby securing one or both of the first retainer 421 and the second retainer 422, and suppressing deformation when one or both of the first retainer 421 and the second retainer 422 are moved. The rigid material may be, for example, rigid resins such as ABS resin, polyoxymethylene resin, polycarbonate resin, polyester resin, and acrylic resin, with ABS resin being particularly suitable. Furthermore, the receiving portion 414 provided in the connecting body 411 is preferably formed of, for example, a soft material so that it can deform when one or both of the first retainer 421 and the second retainer 422 are moved by a force greater than a predetermined magnitude. The soft material may be, for example, the material exemplified in the ear loop 2 or the magnetic retainer 32.

[0044] The cover portion 412 provided by the connecting portion 41 (e.g. Figure 10 and Figure 11 (As shown) The cover portion 412 covers the area around the connecting body 411, protecting the connecting body 411 and preventing the connecting body 411 from contacting human skin. The cover portion 412 has a protrusion 415 protruding in the length direction L from one end (front side, right side in the figure). The protrusion 415 is configured such that when the ear loop portion 2 is in the first rotational position (use position), Figure 6 and Figure 10 When the ear hook 2 is in its first rotational position, it engages with the recess 232 of the ear hook 2, and together with the recess 232 of the ear hook 2, forms the positioning mechanism of the ear hook 2. Thus, the first rotational position of the ear hook 2 becomes a quasi-stable position, thereby easily positioning the ear hook 2 relative to the retaining part 4 at the first rotational position. Furthermore, in this embodiment, two protrusions 415 are provided on the upper and lower sides of the connecting part 413 on the retaining part side. The two protrusions 415 (such as...) Figure 11 (As shown) The protrusions 415 and 415 are spaced apart in the vertical direction by a length substantially equal to the horizontal length (vertical length in the figure) of the mounting portion 23. In other words, the protrusions 415 are configured to engage with the mounting portion 23 of the ear hook portion 2 in the rotational direction centered on the rotation axis X, and together with the mounting portion 23, constitute the positioning mechanism of the ear hook portion 2. Therefore, when the ear hook portion 2 attempts to rotate relative to the retaining portion 4 from its second rotational position about the rotation axis X, the side of the mounting portion 23 engages with the protrusions 415, thereby suppressing its rotation. In this way, the second rotational position of the ear hook portion 2 becomes a quasi-stable position, allowing the ear hook portion 2 to be easily positioned relative to the retaining portion 4 in the second rotational position.

[0045] The material constituting the cover 412 is not particularly limited, and may include thermosetting elastomers such as silicone rubber, polyurethane rubber (U), isoprene rubber (IR), styrene-butadiene rubber (SBR), natural rubber, ethylene propylene diene monomer (EPDM), and nitrile rubber (NBR); thermoplastic elastomers such as polyurethane-based, ester-based, styrene-based, olefin-based, butadiene-based, and fluoropolymer-based elastomers, or their composites. Among these materials, silicone rubber is particularly preferred due to its excellent biocompatibility, heat resistance, and cold resistance.

[0046] The first retainer 421 and the second retainer 422 of the retaining part 4 connect a pair of connecting parts 41, 41 to each other, and retain the magnetic body part 3 by inserting it into the through hole 322 of the magnetic body part 3. Figure 10 and Figure 11 In the example shown, the first retainer 421 is connected in a manner movable relative to the connecting portion 41, and the second retainer 422 is fixed to the connecting portion 41. For Figure 10 and Figure 11 Other connecting portions 41 (not shown) include a first retainer 421 fixed and a second retainer 422 movably connected. The ends of the first retainer 421 and the second retainer 422, which are movably connected relative to the connecting portion 41, are provided with end members 421e. As described above, the end members 421e are configured to fit into the large-diameter portion 414a of the receiving portion 414 of the connecting portion 41 and engage with the peripheral wall of the small-diameter portion 414b in the longitudinal direction L. Thus, the end members 421e at the front ends of the first retainer 421 and the second retainer 422 can maintain their position quasi-stable within the large-diameter portion 414a of the receiving portion 414. On the other hand, when the first retainer 421 and the second retainer 422 move along the longitudinal direction L with a force greater than a predetermined magnitude, the peripheral wall of the small-diameter portion 414b of the receiving portion 414 can be deformed, thereby moving to the adjacent large-diameter portion 414a. In this way, the first retainer 421 and the second retainer 422 are connected in a manner movable relative to the connecting portion 41 in the longitudinal direction L.

[0047] The end members 421e located at the ends of the first retainer 421 and the second retainer 422 are preferably formed of, for example, a rigid material, so as to suppress deformation when the first retainer 421 and the second retainer 422 move relative to the receiving portion 414 of the connecting portion 41. The rigid material may be, for example, rigid resins such as ABS resin, polyoxymethylene resin, polycarbonate resin, polyester resin, and acrylic resin, wherein ABS resin is suitable.

[0048] The first retainer 421 and the second retainer 422 preferably have a predetermined stiffness to suppress deformation due to the weight of the magnetic material portion 3 when holding the magnetic body portion 3. The predetermined stiffness of the first retainer 421 and the second retainer 422 allows for more stable maintenance of the position of the magnetic body portion 3. Furthermore, the first retainer 421 and the second retainer 422 are preferably elastically deformable from their initial shape and have a restoring force to return to that initial shape after deformation. The elastic deformability of the first retainer 421 and the second retainer 422 makes the magnetic therapy device 1 easy to operate and wear on the human body. Additionally, the restoring force of the first retainer 421 and the second retainer 422 ensures that even if the first retainer 421 and the second retainer 422 are deformed by external force during use, causing displacement of the magnetic body portion 3, the restoring force allows the first retainer 421 and the second retainer 422 to return to their initial shape, returning the magnetic body portion 3 to its original position, thereby suppressing positional displacement of the magnetic body portion 3. For this purpose, in this embodiment, as... Figure 10 and Figure 11 As shown, the first retainer 421 and the second retainer 422 respectively have predetermined rigidity, are capable of elastic deformation, have restoring force, and have long ruler-shaped core materials 421a and 422a extending along the length direction L, and covering materials 421b and 422b covering the core materials 421a and 422a.

[0049] The core materials 421a and 422a are not particularly limited as long as they possess the predetermined rigidity, elastic deformation capability, and restoring force; for example, they can be made of shape memory alloys. Examples of shape memory alloys include iron-based shape memory alloys, copper-based shape memory alloys, and nickel-titanium shape memory alloys. Examples of iron-based shape memory alloys include Fe-Mn-Si alloys. Examples of copper-based shape memory alloys include Cu-Zn-Al alloys or Cu-Al-Ni alloys. Examples of nickel-titanium shape memory alloys include Ni-Ti alloys, Ni-Ti-Co alloys, and Ni-Ti-Cu alloys. Among these shape memory alloys, nickel-titanium shape memory alloys are preferred due to their excellent thermomechanical properties.

[0050] Covering materials 421b and 422b protect core materials 421a and 422a and prevent core materials 421a and 422a from contacting human skin. There are no particular limitations on the materials constituting covering materials 421b and 422b, such as thermosetting elastomers like silicone rubber, polyurethane rubber (U), isoprene rubber (IR), styrene-butadiene rubber (SBR), natural rubber, ethylene propylene diene monomer (EPDM), and nitrile rubber (NBR); or thermoplastic elastomers like polyurethane-based, ester-based, styrene-based, olefin-based, butadiene-based, and fluoropolymer-based elastomers; or their composites. Among these materials, silicone rubber is particularly preferred due to its excellent biocompatibility, heat resistance, and cold resistance.
