Detailed Description

Hereinafter, a magnetic ornament according to an embodiment of the present invention will be described with reference to the drawings. However, the embodiments described below are merely examples, and the magnetic ornament of the present invention is not limited to the embodiments described below.

As shown in fig. 11, the magnetic ornament 1 of the present embodiment is used by being worn on a human body. As described later, since the magnetic ornament 1 includes the magnetic body 3, it can be used as a magnetic therapeutic device by being worn on a human body. Since the magnetic ornament 1 can be worn on the human body to dispose the magnetic body 3 close to the human body, it is possible to achieve a magnetic therapy effect such as promotion of blood circulation at and around the disposed portion and improvement of metabolism by applying a magnetic field to the inside of the human body. However, the magnetic ornament 1 can be used not only for the application as a magnetic therapeutic device but also for other applications such as decoration. For example, as shown in fig. 11, the magnetic ornament 1 can be worn on the neck N of the human body, but can be worn on other parts.

As shown in fig. 1 to 3, the magnetic ornament 1 includes: a flexible elongated body 2 and a magnetic body 3 embedded in the elongated body 2. The magnetic ornament 1 comprises: the elongated body 2 can be formed into a ring shape by connecting the one end 2a side of the elongated body 2 and the other end 2b side of the elongated body 2 so as to overlap each other. Thus, as shown in fig. 11, the magnetic ornament 1 can be used by being wrapped around a wearing portion such as the neck N of a human body. In the present embodiment, the one end 2a side and the other end 2b side of the elongated body 2 are detachably connected, but may be connected so as not to be detachable.

The elongated body 2 is a flexible, elongated (slender) member extending in the longitudinal direction L. In the present embodiment, as shown in fig. 1 to 3, the elongated body 2 includes a first elongated member 21, a second elongated member 22, and a connecting portion 23 that connects the first elongated member 21 and the second elongated member 22 to each other so as to be separable. The elongated body 2 is configured as one member by connecting the first elongated member 21 and the second elongated member 22 to each other by the connecting portion 23, and can be divided between the first elongated member 21 and the second elongated member 22 by releasing the connection by the connecting portion 23. Therefore, even when the magnetic ornament 1 is formed in an annular shape, for example, the long body 2 can be divided by temporarily releasing the connection by the connection portion 23, and can be easily wound around a wearing portion such as the neck N of a human body and worn.

Each of the first elongated member 21 and the second elongated member 22 is a flexible, elongated (slender) member, and constitutes a part of the elongated body 2 in the longitudinal direction L. In the present embodiment, as shown in fig. 2 and 3, the first elongated member 21 is a member extending to the one end 2a of the elongated body 2 and the end 21a opposite to the one end 2a of the elongated body 2. The second elongated member 22 is a member extending to the other end 2b of the elongated body 2 and an end 22a on the opposite side of the other end 2b of the elongated body 2. The first elongated member 21 includes a connecting portion 24 described later, and the second elongated member 22 includes a connected portion 25 described later. The end 21a of the first elongated member 21 and the end 22a of the second elongated member 22 are connected to each other via a connecting portion 23, and the first elongated member 21 and the second elongated member 22 are connected to each other.

Each of the first elongated member 21 and the second elongated member 22 may be formed in an elongated shape, and the shape thereof is not particularly limited. In the present embodiment, as shown in fig. 1 to 5, the first elongated member 21 is formed to have a substantially circular cross section perpendicular to the longitudinal direction L in most (65 to 90% of the entire) range in the longitudinal direction L from one end portion (one end 2a of the elongated body 2), and formed to have a substantially rectangular cross section perpendicular to the longitudinal direction L in the remaining portion up to the other end portion 21 a. The second elongated member 22 is formed to have a substantially rectangular cross section perpendicular to the longitudinal direction L over substantially the entire length from one end (the other end 2b of the elongated body 2) to the other end 22 a. The cross-sectional area of the second elongated member 22 is larger than the cross-sectional area of the first elongated member 21, and the weight per unit length of the second elongated member 22 in the longitudinal direction L is larger than the weight per unit length of the first elongated member 21 in the longitudinal direction L. As a result, when the magnetic ornament 1 is formed in a ring shape, a weight bias is generated in the magnetic ornament 1 as described below.

The length of each of the first elongated member 21 and the second elongated member 22 is not particularly limited, and can be appropriately set according to the length of the elongated body 2, the position at which the elongated body 2 is divided, and the like, as needed. The first elongated member 21 and the second elongated member 22 are not particularly limited as long as they have flexibility at least enough to allow the elongated body 2 to bend into a ring shape in a state in which the elongated body 2 is constructed by being connected to each other, and they can be formed of a soft material such as silicone rubber, urethane rubber, or urethane rubber. Silicone rubber is preferably used because it has a relatively small adverse effect on the skin and also has a relatively good skin feel. The first elongated member 21 and the second elongated member 22 may be formed of the same material, or may be formed of different materials.

The connecting portion 23 is not particularly limited as long as it can connect the first elongated member 21 and the second elongated member 22 to each other. In the present embodiment, as shown in fig. 1 to 3, the coupling portion 23 includes: an insertion member 231 inserted between the end 21a of the first elongated member 21 and the end 22a of the second elongated member 22, and an engagement member 232 engaged with the first elongated member 21 and the second elongated member 22.

As shown in fig. 1 to 3, the insertion member 231 is disposed between the end 21a of the first elongated member 21 and the end 22a of the second elongated member 22, and constitutes a part of the elongated body 2 in the longitudinal direction L. The insertion member 231 holds the engagement member 232 in a state of engaging with the engagement member 232 inserted through and inserted into the elongated body 2 along the longitudinal direction L. The insertion member 231 has substantially the same cross-sectional shape and cross-sectional area as the vicinity of the end 21a of the first elongated member 21 and the vicinity of the end 22a of the second elongated member 22. The insertion member 231 may have a strength enough to hold the engagement member 232 in a state of being engaged with the engagement member 232, and may be formed of a soft material such as silicone rubber, urethane rubber, or urethane rubber, without particular limitation. The insertion member 231 may be formed of the same material as the first elongated member 21 and the second elongated member 22, or may be formed of a different material. By improving the color or shape of the insertion member 231, it is possible to provide both a decorative function and an easy recognition of the connection portion by the user.

The engaging member 232 is held by the insertion member 231 by engaging with the insertion member 231, and is engaged with and disengaged from the first long member 21 and the second long member 22. The engaging member 232 passes through the insertion member 231 and is inserted into the insertion member 231. As shown in fig. 3, the engaging member 232 includes a first engaging portion 232a protruding from the insertion member 231 toward the end 21a of the first elongated member 21 in a state of being inserted through the insertion member 231, a second engaging portion 232b protruding from the insertion member 231 toward the end 22a of the second elongated member 22, and a third engaging portion 232c located between the first engaging portion 232a and the second engaging portion 232b and engaging with the insertion member 231. The first engaging portion 232a is engageable with a first elongated member-side engaged portion 21b provided adjacent to the end portion 21a of the first elongated member 21 so as to be engageable with and disengageable from the first elongated member, and the second engaging portion 232b is engageable with a second elongated member-side engaged portion 22b provided adjacent to the end portion 22a of the second elongated member 22 so as to be engageable with and disengageable from the second elongated member-side engaged portion. The first long member 21 and the second long member 22 are pulled in opposite directions to each other along the longitudinal direction L by a force larger than a predetermined force (engagement force), whereby the connection (engagement) of the first long member 21 and the second long member 22 connected to each other by the connection portion 23 is released between the first long member 21 and the connection portion 23 (between the first long member-side engaged portion 21b and the first engagement portion 232 a) and/or between the second long member 22 and the connection portion 23 (between the second long member-side engaged portion 22b and the second engagement portion 232 b).

The engaging member 232 is not particularly limited as long as it has a strength enough to suppress deformation when engaged with and disengaged from the first elongated member 21, the second elongated member 22, and the insertion member 231, and when the magnetic ornament 1 is used, and may be formed of, for example, a hard resin such as polyethylene and hard polyvinyl chloride, a hard material such as a metal, or a soft material such as a soft resin.

As described above, in the present embodiment, the elongated body 2 includes two separable members, i.e., the first elongated member 21 and the second elongated member 22. However, the elongated body 2 is not limited to the present embodiment, and may be formed of one member that cannot be separated. The length of the elongated body 2 is not particularly limited, and can be appropriately set according to the size of the part of the human body to be worn. The elongated body 2 is not particularly limited as long as it has flexibility to the extent that it can be bent into a ring shape, and can be formed of a soft material such as silicone rubber, urethane rubber, or urethane rubber.

As shown in fig. 2 and 3, the long body 2 is provided with a connecting portion 24 which can be overlapped and connected with the other end 2b side of the long body 2 in a predetermined length range in the longitudinal direction L of the long body 2 from the one end 2a side of the long body 2 on the one end 2a side of the long body 2, and provided with a connected portion 25 which can be overlapped and connected with the connecting portion 24 in a predetermined length range in the longitudinal direction L of the long body 2 from the other end 2b side of the long body 2 on the other end 2b side of the long body 2. The magnetic ornamental article 1 can be formed into a ring shape by connecting the connecting portion 24 and the connected portion 25 of the elongated body 2 so as to overlap each other. As will be described in detail later, the connecting portion 24 and the connected portion 25 are connected to each other so that the length in the longitudinal direction L of the overlapping region OL (see fig. 2) overlapping each other can be adjusted. The magnetic ornamental article 1 is capable of adjusting the length (or diameter) of the ring by adjusting the length of the overlapping region OL.

In the present embodiment, the connecting portion 24 and the connected portion 25 are provided separately from the connecting portion 23. Thus, the coupling operation by the coupling portion 23 and the adjustment operation of the loop length via the coupling portion 24 and the coupled portion 25 for attaching the magnetic ornament 1 to the human body can be independently performed. Therefore, since it is not necessary to adjust the length of the magnetic ornament 1 every time the magnetic ornament 1 is attached to the human body, the operation of the magnetic ornament 1 is easy. The magnetic ornament 1 of the present embodiment is configured such that: the force required to release the coupling by the coupling portion 23 is larger than the force required to change (e.g., shorten) the length in the longitudinal direction L of the overlapping region between the coupling portion 24 and the coupled portion 25. Thus, even if the elongated body 2 is pulled in a direction in which the length of the loop is increased, and the same force is simultaneously applied to the coupling portion 23, and both the coupling portion 24 and the coupled portion 25, the length of the overlapping area OL is reduced and the length of the loop is increased before the coupling of the coupling portion 23 is released. Therefore, the coupling of the coupling portion 23 is suppressed from being unintentionally released when the length of the loop is extended while the length of the overlap region OL is shortened, so that the loop length can be easily adjusted.

In the present embodiment, as shown in fig. 1 and 2, the magnetic ornament 1 is formed by: in the ring-shaped state, a region of half the length of the ring (lower side in the figure) has a larger weight than a region of the other half of the length of the ring (upper side in the figure). More specifically, the region having a relatively large weight mainly includes a region having a substantially rectangular cross section, a relatively large cross section, and a large weight per unit length (including a part of the first elongated member 21 and the second elongated member 22), and the region having a relatively small weight mainly includes a region having a substantially circular cross section, a relatively small cross section, and a small weight per unit length (including a part of the first elongated member 21). By making the half-length region of the ring relatively heavier than the other half-length region of the ring, for example, as shown in fig. 11, when the magnetic ornament 1 is worn on the neck portion N with the relatively heavier region disposed on the lower side, the relatively heavier region is maintained on the lower side in association with gravity, and rotation around the neck portion N is suppressed. This can suppress the change in the position of the magnetic body 3 with respect to the neck portion N, and therefore can continuously provide a magnetic therapy effect at a desired position. The magnetic ornamental article 1 of the present embodiment can exhibit a desired magnetotherapeutic effect by suppressing the rotation of the magnetic ornamental article 1 with respect to the neck portion N even when the magnetic ornamental article 1 vibrates with respect to the neck portion N as a result of, for example, a user performing exercise. Therefore, the magnetic ornament 1 of the present embodiment can be preferably used for sports applications.

As shown in fig. 2 and 3, the connecting portion 24 constitutes a portion of the elongated body 2 within a predetermined length range in the longitudinal direction L of the elongated body 2 from the one end 2a of the elongated body 2. The connecting portion 24 is not particularly limited as long as it can be connected to the connected portion 25 so as to overlap the connected portion 25 and to adjust the length of the overlapping region OL. In the present embodiment, the connecting portion 24 includes a connecting portion main body 241 extending along the longitudinal direction L of the connecting portion 24 and a plurality of engaging portions 242 engageable with the connected portion 25.

The connecting portion main body 241 extends along the longitudinal direction L of the connecting portion 24 over the entire length of the connecting portion 24 in the longitudinal direction L. The connecting unit main body 241 is connected to the connected unit 25 (connected unit main body 251 to be described later) so as to be slidable along the longitudinal direction L and have a predetermined sliding resistance. When a force equal to or less than a predetermined sliding resistance is applied between the connecting portion 24 and the connected portion 25 in the longitudinal direction L, the connecting portion 24 is prevented from sliding with respect to the connected portion 25, the connecting position with respect to each other is maintained, and the length of the overlapping region OL is maintained. When a force greater than a predetermined sliding resistance is applied between the connecting portion 24 and the connected portion 25 in the longitudinal direction L, the connecting portion 24 slides relative to the connected portion 25, the connecting position relative to each other changes, and the length of the overlapping area OL changes. By applying a force greater than a predetermined sliding resistance between the connecting portion 24 and the connected portion 25 in the longitudinal direction L, the length of the overlapping region OL can be adjusted, and the length of the ring can be adjusted.

In the present embodiment, as shown in fig. 2 to 4, the connecting portion main body 241 is formed in an elongated shape having a substantially circular cross section perpendicular to the longitudinal direction L. The connecting portion main body 241 is formed to have a size that can be fitted into a receiving portion 252, which will be described later, of the connected portion 25 in the longitudinal direction L.

The engaging portion 242 is engageable with and disengageably engageable with the connected portion 25 in the longitudinal direction L, and suppresses relative movement of the connecting portion 24 and the connected portion 25 with respect to each other in the longitudinal direction L. By engaging the engaging portion 242 with the connected portion 25 (the engaged portion 253 described later), the connection position between the connecting portion 24 and the connected portion 25 can be maintained more stably, and the length of the overlapping region OL can be maintained more stably. On the other hand, the engagement between the engaging portion 242 and the connected portion 25 can be released by applying a force greater than the engaging force between the engaging portion 242 and the connected portion 25 in the longitudinal direction L between the connecting portion 24 and the connected portion 25.

As shown in fig. 2 and 3, each of the plurality of engaging portions 242 is provided apart from each other along the longitudinal direction L of the connecting portion 24. Thus, the length of the overlapping area OL can be adjusted by engaging the connected portion 25 at any position of the plurality of engaging portions 242, and the connected state can be maintained more stably at the position where the length of the overlapping area OL is adjusted. In the present embodiment, each of the plurality of engaging portions 242 is disposed at substantially equal intervals from each other along the longitudinal direction L of the connecting portion 24.

The plurality of engaging portions 242 may be configured to engage with the connected portion 25 with the same engaging force, or may be configured to engage with different engaging forces. In the present embodiment, the configuration is such that: the engaging portion 242 adjacent to the one end 2a of the elongated body 2 engages with the connected portion 25 with a higher engaging force than the other engaging portion 242 distant from the one end 2a of the elongated body 2. More specifically, as is more clearly seen in fig. 3, the length in the longitudinal direction L of the engaging portion 242 adjacent to the one end 2a of the elongated body 2 is longer than the length in the longitudinal direction L of the other engaging portion 242 distant from the one end 2a of the elongated body 2, so that the engaging portion 242 adjacent to the one end 2a of the elongated body 2 is less likely to disengage from the connected portion 25 than the other engaging portion 242 (the engaging force is higher). This maximizes the engaging force when the length of the overlap region OL is the shortest, and the length of the overlap region OL can be most suppressed from becoming shorter (the connection between the connecting portion 24 and the connected portion 25 is released). On the other hand, in a state where the length of the overlapping area OL is longer, the engagement between the other engagement portion 242 and the connected portion 25 is relatively easily released, so that the length of the overlapping area OL can be easily adjusted.

As shown in fig. 4, each of the plurality of engaging portions 242 is configured as a protruding portion protruding from the connecting portion main body 241 in a direction substantially perpendicular to the longitudinal direction L of the connecting portion 24 (upward in the drawing). The engaging portion 242 is configured to protrude from the connected portion 25 in a state where the connecting portion 24 is connected to the connected portion 25. In the present embodiment, the plurality of engaging portions 242 are formed on one side (the front side of the paper in fig. 2 and 3, and the upper side in fig. 4) in the direction substantially perpendicular to the plane on which the ring is formed in the state where the magnetic ornamental article 1 is formed in the ring shape. In the present embodiment, the engaging portion 242 is configured as a protruding portion protruding from the connecting portion main body 241, but is not limited to the present embodiment as long as it can engage with the connected portion 25, and may be configured as a recessed portion recessed from the surface of the connecting portion main body 241.

As shown in fig. 2 and 3, the connected portion 25 constitutes a portion of the elongated body 2 within a predetermined length range in the longitudinal direction L of the elongated body 2 from the other end 2b of the elongated body 2. The connected portion 25 is not particularly limited as long as it can be connected to the connecting portion 24 so as to overlap the connecting portion 24 and to adjust the length of the overlapping region OL. In the present embodiment, the receiving portion 252 capable of receiving the entire connecting portion 24 located in the overlapping area OL in the longitudinal direction L is provided in the connected portion 25. The connecting portion 24 located in the overlapping region OL is held in the holding portion 252 while contacting the connected portion 25 so that the entire connecting portion 24 in the longitudinal direction L is not separated from the connected portion 25. By housing the entire connecting portion 24 in the longitudinal direction L in the overlapping region OL in the housing portion 252, the external force applied by the fingers or the like hooking to one or both of the connecting portion 24 and the connected portion 25 in the overlapping region OL is suppressed, and the change in the length of the ring when worn on the human body is suppressed.

In the present embodiment, as shown in fig. 2 and 3, the connected portion 25 includes a connected portion main body 251 extending along the longitudinal direction L of the connected portion 25, the receiving portion 252 provided in the connected portion main body 251, and an engaged portion 253 engageable with the engaging portion 242 of the connecting portion 24.

The connected portion main body 251 is a portion extending along the longitudinal direction L of the connected portion 25 over the entire length of the connected portion 25 in the longitudinal direction L. The connected portion main body 251 is connected to the connecting portion 24 (connecting portion main body 241) so as to be slidable along the longitudinal direction L with a predetermined sliding resistance. The connected portion main body 251 holds the connecting portion 24 housed in the housing portion 252. As shown in fig. 4, the connected portion main body 251 includes an opening 251a that opens in a direction substantially perpendicular to the longitudinal direction L of the connected portion 25, a bottom 251b that faces the opening 251a, and a pair of side portions 251c, 251c that are provided so as to stand from both ends of the bottom 251b (in the direction substantially perpendicular to the longitudinal direction L of the connected portion 25). The opening 251a, the bottom 251b, and the pair of side portions 251c, 251c are provided so as to extend over the entire length of the connected portion main body 251 in the longitudinal direction L.

In the present embodiment, as shown in fig. 1 to 4, the connected portion-receiving main body 251 is formed in an elongated shape having a substantially rectangular cross section perpendicular to the longitudinal direction L and extending along the longitudinal direction L as a whole. The connected portion main body 251 is formed such that the cross-sectional area of the cross-section perpendicular to the longitudinal direction L is larger than the cross-sectional area of the cross-section perpendicular to the longitudinal direction L of the connecting portion main body 241. The connected portion main body 251 is configured to: the opposing sides (sides) of the rectangle face one side (front side of the paper of fig. 2 and 3, upper side of fig. 4) and the other side (front side of the paper of fig. 1, lower side of fig. 4) in the direction substantially perpendicular to the plane formed by the ring when the magnetic ornament 1 is formed in a ring shape. For example, as shown in fig. 11, when the magnetic ornament 1 is worn on the neck N of the human body, the surface formed by the sides of the rectangle faces the skin on the lower side of the neck N, and therefore the wearing position is maintained more stably with respect to the neck N.

In the present embodiment, as shown in fig. 4, the housing portion 252 is configured to have a recess that is recessed into the inside of the connected portion 25 (connected portion main body 251) toward an opening 251a that opens in a direction substantially perpendicular to the longitudinal direction L of the connected portion 25. The concave portion 252 is formed: in a state where the connection portion 24 is housed in the recess 252, the protruding portion (engagement portion) 242 of the connection portion 24 protrudes from the opening 251a of the recess 252 to the outside of the recess 252. Therefore, the connecting portion 24 is accommodated in the concave portion 252 so that the protruding portion 242 protrudes from the opening 251a to the outside of the concave portion 252. Thus, for example, if the magnetic ornament 1 is worn on the human body so that the protruding portion 242 faces the human body side, the protruding portion 242 is brought into direct or indirect contact with and engaged with the skin of the human body, thereby suppressing the movement (particularly, the rotation) of the magnetic ornament 1 with respect to the wearing portion of the human body. For example, even when the user moves and the magnetic ornament 1 vibrates with respect to the wearing portion, the movement of the magnetic ornament 1 with respect to the wearing portion is suppressed, and therefore, the change in the position of the magnetic body 3 with respect to the wearing portion can be suppressed. Therefore, the magnetic ornament 1 of the present embodiment can be preferably used also for sports use.

As shown in fig. 4, the concave portion 252 is formed inside a bottom portion 251b of the connected portion main body 251 facing the opening 251a and a pair of side portions 251c, 251c provided upright from both ends of the bottom portion 251 b. The concave portion 252 is formed in such a size that the connecting portion main body 241 of the connecting portion 24 comes into contact with the bottom portion 251b and the pair of side portions 251c, 251c in a state where the connecting portion 24 is accommodated in the concave portion 252. Thus, the connection portion 24 is housed in the recess 252 in a state where the protruding portion 242 protrudes from the opening 251a to the outside of the recess 252 and the connection portion main body 241 is fitted in the recess 252. The connecting portion 24 is slidably connected to the connected portion 25 by contacting the bottom portion 251b and the pair of side portions 251c, 251c of the connected portion 25 to have a predetermined sliding resistance.

As shown in fig. 4, the recess 252 is formed such that the width W1 of the opening 251a is smaller than the interval W2 between the pair of side portions 251c, 251 c. This suppresses the connection portion 24 having a width corresponding to the distance W2 between the pair of side portions 251c, 251c from falling off from the recess 252 via the opening 251 a. When the connecting portion 24 is intended to rotate about the axis along the longitudinal direction L with respect to the connected portion 25, the pair of side portions 251c, 251c abut against the protruding portion 242 protruding from the opening portion 251a, so that relative rotation of the connecting portion 24 about the axis along the longitudinal direction L is suppressed, and the guide connecting portion 24 moves relative to the connected portion 25 in the longitudinal direction L without twisting.

As shown in fig. 2 to 4, the concave portion 252 is disposed such that: the opening 251a of the recess 252 faces one side (the front side of the paper in fig. 2 and 3, and the upper side in fig. 4) in the direction substantially perpendicular to the plane formed by the ring when the magnetic ornament 1 is formed in a ring shape. That is, the opening 251a of the concave portion 252 opens in the same direction as the protruding portion 242 of the connecting portion 24 protrudes. Thus, the protrusion 242 and the opening 251a are aligned with each other, whereby the connecting portion 24 can be prevented from being twisted from a predetermined angle with respect to the connected portion 25 and can be accommodated. Further, since the projecting portion 242 projects to one side in the direction substantially perpendicular to the plane formed by the ring when the magnetic ornament 1 is formed in the ring shape, for example, as shown in fig. 11, when the magnetic ornament 1 is worn on the neck portion N of the human body, the plurality of engaging portions 242 can be worn so as to be engaged with the skin on the lower side of the neck portion N of the human body in direct or indirect contact, and therefore, the magnetic ornament 1 is suppressed from rotating around the neck portion N.

As shown in fig. 5, a bridge 251d extending between the pair of side portions 251c, 251c is provided above the recess 252 (on the opposite side of the bottom portion 251b of the opening 251 a) so as to close a part of the opening 251a in the longitudinal direction L. The space surrounded by the bottom portion 251b, the pair of side portions 251c, and the bridge portion 251d constitutes an insertion hole 251e through which the connecting portion 24 can be inserted slidably. By providing the bridge 251d above the recess 252, the connection portion 24 housed in the recess 252 below the bridge 251d is prevented from falling out of the recess 252 through the opening 251a, and the connection portion 24 is more reliably housed in the recess 252.

The engaged portion 253 engages with the engaging portion 242 of the connecting portion 24 in the longitudinal direction L, thereby suppressing relative movement of the connecting portion 24 with respect to the connected portion 25 in the longitudinal direction L. As shown in fig. 2 and 3, the engaged portion 253 is provided in parallel with the accommodating portion (recess) 252 at a part of the accommodating portion (recess) 252 in the longitudinal direction L. By providing the engaged portion 253 in parallel with the receiving portion 252, the connecting portion 24 can be more reliably received in the receiving portion 252 while suppressing relative movement with respect to the connected portion 25 in the longitudinal direction L. The engaged portion 253 is provided adjacent to the other end 2b of the elongated body 2 (at a distance approximately equal to the length of one engaging portion 242 in the longitudinal direction L). Thus, the connecting portion 24 and the connected portion 25 can be engaged with each other in the vicinity of the other end 2b of the elongated body 2, and the connected state between the connecting portion 24 and the connected portion 25 can be maintained in a state where the length of the overlapping region OL is shorter.

In the present embodiment, the engaged portion 253 is formed of a bridge 251d (see fig. 5). By configuring the engaged portion 253 with the bridge portion 251d, relative movement of the connecting portion 24 in the longitudinal direction L and in the direction perpendicular to the longitudinal direction L at the same position in the longitudinal direction L can be suppressed, and the connected state of the connecting portion 24 with respect to the connected portion 25 can be maintained more stably.

In the present embodiment, the engaged portion 253 is configured to engage with the engaging portion 242 of the connecting portion 24, and thereby suppresses both relative movement of the connecting portion 24 with respect to the connected portion 25, which shortens the length of the overlapping area OL, and relative movement of the connecting portion 24 with respect to the connected portion 25, which lengthens the length of the overlapping area OL. More specifically, as shown in fig. 2, the end portion on one side (the one end 2a side of the elongated body 2) of the bridge portion 251d constituting the engaged portion 253 is engaged with the engaging portion 242 on one side (the one end 2a side of the elongated body 2) of the adjacent engaging portions 242 of the connecting portion 24, thereby suppressing relative movement of the connecting portion 24 with respect to the engaged portion 25, which shortens the length of the overlapping region OL. Further, the other end portion (the other end 2b side of the elongated body 2) of the bridging portion 251d is engaged with the other engaging portion 242 (the other end 2b side of the elongated body 2) of the adjacent engaging portions 242 of the connecting portion 24, thereby suppressing relative movement of the connecting portion 24 with respect to the connected portion 25, which increases the length of the overlapping region OL. In the present embodiment, the length of the bridge portion 251d in the longitudinal direction L of the connected portion 25 substantially matches the interval between the engaging portions 242 adjacent to each other in the longitudinal direction L of the connecting portion 24. Therefore, the engaged portion 253 is disposed between the adjacent engaging portions 242, and is engaged with both of the engaging portions 242 of the adjacent engaging portions 242. This can suppress relative movement in two directions along the longitudinal direction L of the connecting portion 24, and can maintain the length of the overlapping region OL more stably.

The magnetic body 3 generates a magnetic field, and particularly generates a magnetic field that can affect a part of a human body (for example, a magnetic therapy effect). In the present embodiment, as shown in fig. 1 to 3, the magnetic body 3 is formed in a granular shape and embedded in the elongated body 2. More specifically, as shown in fig. 6, the magnetic substance 3 formed in a granular shape is embedded in the elongated body 2 as follows: the center axis C extending in the longitudinal direction L of the elongated body 2 is eccentric to one side (the front side of the paper of fig. 2 and 3, the upper side of fig. 4) in the direction substantially perpendicular to the plane formed by the ring in the state where the magnetic ornamental article 1 is formed in the ring shape. Therefore, when the magnetic ornament 1 is worn on the human body so that one side of the ornament in the direction substantially perpendicular to the plane formed by the ring faces the skin of the human body in the state where the ornament is formed in the ring shape, the magnetic body 3 is disposed on the side closer to the human body, so that a larger magnetic field can be generated in the human body and a higher magnetic therapy effect can be exhibited.

In the present embodiment, as shown in fig. 1 to 3, the magnetic substance 3 includes a plurality of (6 in the illustrated example) magnetic substances arranged so that the intervals between the magnetic substances along the longitudinal direction L of the elongated body 2 (first elongated member 21) are substantially equal. However, the number of the magnetic bodies 3 is not particularly limited, and may be one. The magnetic substance 3 may be formed in a powder form and dispersed in the elongated body 2, whereby the elongated body 2 may be configured as a rubber magnet. The magnetic material 3 is not particularly limited as long as it generates a magnetic field, and for example, a magnetic material such as ferrite, neodymium, or samarium cobalt can be used.

Next, a method of adjusting the length (or diameter) of the adjustment ring of the magnetic ornament 1 according to the present embodiment will be described with reference to fig. 7 to 10. However, the magnetic ornament of the present invention is not limited to the following description.

First, in order to form the magnetic ornament 1 into a ring shape, as shown in fig. 7, the connecting portion 24 provided on the one end 2a side of the elongated body 2 is inserted from the other end 2b side of the elongated body 2 to the insertion hole 251e of the connected portion 25 provided on the other end 2b side of the elongated body 2, and is connected to the connected portion 25. At this time, the portion of the connecting portion 24 located near the engaged portion 253 of the connected portion 25 is in a state of being accommodated in the accommodating portion 252 of the connected portion 25, and the portion on the tip end (one end 2a of the elongated body 2) side of the connecting portion 24 is in a state of protruding from the accommodating portion 252 and not being accommodated in the accommodating portion 252.

Next, as shown in fig. 8, the connecting portion 24 is pulled relative to the connected portion 25 (from right to left in the drawing) so as to increase the length of the overlapping region OL against the sliding resistance between the connecting portion main body 241 of the connecting portion 24 and the connected portion 25 and the engaging force between the engaging portion 242 of the connecting portion 24 and the engaged portion 253 of the connected portion 25, thereby moving relative to the connected portion 25. Thereby, the length of the overlapping region OL can be extended and the length (or diameter) of the ring of the magnetic ornamental article 1 can be shortened.

Next, when the overlap area OL reaches a required length, as shown in fig. 9, the entire connecting portion 24 located in the overlap area OL in the longitudinal direction L is accommodated in the accommodating portion 252 of the connected portion 25. By housing the entire connecting portion 24 in the longitudinal direction L in the overlapping region OL in the housing portion 252, the external force applied by the fingers or the like hooking to one or both of the connecting portion 24 and the connected portion 25 in the overlapping region OL is suppressed, and the change in the length of the ring when worn on the human body is suppressed.

When the length of the overlap region OL is shortened and the length of the loop of the magnetic ornament 1 is lengthened (increased in diameter) from the state shown in fig. 9, the connecting portion 24 is pulled in a direction away from the connected portion 25 (from left to right in the drawing) against the sliding resistance and the engaging force in the state where the connecting portion 24 is accommodated in the accommodating portion 252, whereby the connecting portion 24 is moved relative to the connected portion 25 until the state shown in fig. 10. This can shorten the length of the overlap region OL and extend the length (increase the diameter) of the ring of the magnetic ornament 1.

Conversely, when the length of the overlap region OL is extended from the state shown in fig. 10 and the length of the loop of the magnetic ornamental article 1 is shortened (reduced in diameter), the portion on the tip end side of the connecting portion 24 (the one end 2a of the elongated body 2) is projected from the receiving portion 252 of the connected portion 25 to be in the state shown in fig. 7, the connecting portion 24 is moved relative to the connected portion 25 (see fig. 8), and the connecting portion 24 is received in the receiving portion 252 (see fig. 9). This can extend the length of the overlap region OL and shorten the length (diameter) of the ring of the magnetic ornament 1.

When the magnetic ornament 1 formed in the ring shape is worn on the neck N of the human body, first, the first elongated member 21 and the second elongated member 22 are pulled in a direction in which the first elongated member 21 and the second elongated member 22 are separated from each other, and the connection by the connection portion 23 is released, whereby the end portion 21a of the first elongated member 21 and the end portion 22a of the second elongated member 22 are separated. Then, after the magnetic ornament 1 is wound around the neck portion N, the end portion 21a of the first elongated member 21 and the end portion 22a of the second elongated member 22 are again coupled by the coupling portion 23, whereby the magnetic ornament 1 can be worn on the neck portion N by forming the magnetic ornament 1 in a ring shape.
