Description

  The present invention relates to a jewelry such as a necklace that is wound around the body.

    Generally, jewelry such as a necklace is formed in a string shape, and both ends are provided with a stopper composed of a pair of hooks or the like that can be assembled to each other and detachably locked. When wearing such an accessory on the neck of the body, the user holds both ends of the accessory in their hands, places the middle part of the accessory behind the neck, and then turns both ends toward the front of the neck. After winding, the fasteners, such as heels, provided at both ends of the accessory are locked. As a result, the accessory is wound around the neck in a ring shape and closed.

    There are various types of fasteners for jewelry. For example, a pin that can be moved in and out is provided on one end of the accessory, and a ring is provided on the other end, and the pin is passed through this ring to lock them together. There is a structure in which a ring that can be opened and closed is provided on one end side of the accessory, and the other end side of the accessory is inserted into this ring so as to be attached in a ring shape having an arbitrary diameter.

    Usually, these stoppers are often configured in a small size so as not to affect the decorative effect of the accessory, for example, a small size that can be gradually picked with a finger. In the case of such a stop, there is often no support for attaching and removing accessories, etc. for young people, persons with high visual acuity, and persons with good finger sensations, but for elderly people, people with low vision, and fingers For people who do not feel good, operations such as attaching and removing accessories may be difficult.

    On the other hand, conventionally, there is a configuration in which a magnet is used as a stopping means for a necklace or the like so that the wearing operation of the accessory can be easily performed. For example, it has been proposed that a magnet powder is mixed into a string-like material and configured as a plastic magnet or a rubber magnet by injection molding or extrusion molding (see, for example, Patent Documents 1 and 2).

JP 2002-119313 A JP-A-10-165211

    In the plastic magnets and rubber magnets described in Patent Documents 1 and 2, etc., the amount of the magnet material contained is limited, so that the resultant attractive force is as weak as about 300 gauss. For this reason, when applied to the fastening means of jewelry, it is impossible to perform strong fastening, and it is easily detached by a pulling action by human power. Therefore, when an elderly person or the like wears such an easily-attached accessory, for example, there is a tendency that theft damage caused by another person peeling the accessory from the wearer increases.

    On the other hand, there is also known a configuration in which a stopper using a metal magnet having a high absorption force is made separately from the main body portion of the jewelry as a stopping means for the accessory, and the stopper using this metal magnet is incorporated into the main body portion from the outside. However, in this case, the magnetic attractive force of the magnet becomes excessively strong, which may cause inconvenience in use, such as making it difficult for the user to remove the accessory.

    The present invention has been made in view of such circumstances, and can be easily and reliably stopped in a looped ring shape, enhances safety against theft and the like, and is easy to wear to the user and is used. An object of the present invention is to provide an accessory with good wearability and detachability.

  The jewelry of the present invention includes a tube formed of a flexible material, a magnet inserted into the tube, a cap that closes both ends of the tube, a flexible outer shell into which the tube is inserted, An outer cap for closing both ends of the outer skin is provided, and both ends in the length direction are attracted to each other by the attractive force of the magnet, thereby forming a ring shape as a whole.

  In the jewelry, the plurality of magnets are inserted in the entire range of the tube in the length direction. In addition to the magnet, a spacer made of a non-magnetic material or a magnetic material is inserted into the tube, and the plurality of magnets are disposed at least at both ends of the tube.

  The magnet is rotatable inside the tube, and further includes a stopper for aligning one end side and the other end side in the length direction of the accessory in parallel. And

Furthermore, the accessory of the present invention is an accessory in which the core wire is formed in a ring-shaped endless shape, and the core member is inserted into a plurality of decorative members so that the decorative member is in a chain shape,
The core wire is formed of a shape memory alloy that recovers in a ring shape at about 30 ° C. or higher.

    According to the present invention, since both ends in the length direction are mutually attracted by the attractive force of the magnet inserted into the tube made of a flexible material, the whole becomes a ring shape. Thus, it is possible to increase the safety against theft and the like, to improve the wearability to the user, and to make the accessory that the user can wear and remove.

Then, the accessory 24 is lowered to both sides from the back of the neck 34 of the wearer 33 so that both ends of the accessory 24 are aligned in front of the shoulder 35 and the one end side 36 and the other end side 37 of the accessory 24 are overlapped. Then, as soon as the one end side 36 and the other end side 37 of the accessory 24 are moved to a position close to each other by a certain distance, they are immediately attracted to each other by the attractive force. That is, the wearer 33 is easily and quickly attracted by a strong magnetic force simply by bringing the one end side 36 and the other end side 37 of the accessory 24 close to each other in front of the neck 34.

    The adsorption action by this attractive force will be described with reference to FIG. FIG. 10 is an enlarged partial cross-sectional view showing a portion D in FIG. 9, that is, an overlapping portion of the one end side 36 and the other end side 37 of the accessory 24 at the front lower side of the neck 34. The magnet structure and the adsorption | suction effect | action in the jewelry main body 11 in the end side 37 are shown.

    As shown in FIG. 10, in the overlapping portion of the one end side 36 and the other end side 37 of the accessory 24, for example, four one end side magnets 13 are provided in the accessory main body 11 on the one end side 36 from the one end side outer cap 26 side. (13a, 13b, 13c, 13d) are arranged in series. As described above, these magnets 13 (13a, 13b, 13c, 13d) are each formed in a columnar shape, and each of the magnets 13 (13a, 13b, 13c, 13d) has an N pole (N) and an S pole ( S) is arranged on the outer peripheral surfaces on the opposite sides of the cylinder. The N poles (N) and S poles (S) of the magnets 13 (13a, 13b, 13c, 13d) adjacent to each other are arranged in a staggered direction. Specifically, the north pole (N) of the one end side magnet 13a arranged closest to the one end side outer cap 26 side of the accessory 24 shown on the right side of FIG. 10 is facing left and the south pole (S). Is facing right. The N pole (N) of the one end side magnet 13b arranged second from the end side adjacent to the one end side magnet 13a is directed to the right, and the S pole (S) is directed to the left. Further, the third one end side magnet 13c from the end side adjacent to the one end side magnet 13b has a north pole (N) facing left and a south pole (S) facing right opposite to the second one end magnet 13b. It has become. Furthermore, the one end side magnet 13d arranged fourth from the end side adjacent to the one end side magnet 13c is opposite to the third one end side magnet 13c, and the N pole (N) faces right and the S pole (S ) Is facing left. Similarly to the above, the subsequent intermediate magnet 15 has N poles (N) and S poles (S) arranged in alternate directions.

    On the other hand, in the overlapping portion of the one end side 36 and the other end side 37 of the accessory 24, the other end side outer cap 27 side has, for example, four other magnets 14 (14a) in the accessory main body 11 on the other end side 37. , 14b, 14c, 14d) are arranged in series. As described above, these magnets 14 (14a, 14b, 14c, 14d) are each formed in a columnar shape, and each magnet 14 (14a, 14b, 14c, 14d) has an N pole (N) and an S pole ( S) is arranged on the outer peripheral surfaces on the opposite sides of the cylinder. The magnets 14 (14a, 14b, 14c, 14d) adjacent to each other have N poles (N) and S poles (S) arranged in alternate directions.

    Specifically, the N pole (N) of the other end side magnet 14a arranged closest to the other end side outer cap 27 side of the accessory 24 is facing left, and the S pole (S) is facing right. It has become. Contrary to the above, the other end side magnet 14b arranged second from the end side adjacent to the other end side magnet 14a has the N pole (N) facing right and the S pole (S) facing left. In the other end side magnet 14c arranged third from the end side adjacent to the other end side magnet 14b, the N pole (N) faces left and the S pole ( S) is pointing to the right. Furthermore, the other end side magnet 14d arranged fourth from the end side adjacent to the other end side magnet 14c is further opposite to the third other end side magnet 14c, and the N pole (N) faces rightward. The south pole (S) is facing left. As for the intermediate magnet 15 that follows, the north pole (N) and the south pole (S) are arranged in alternate directions as described above.

    Therefore, in the overlapping portion between the one end side 36 and the other end side 37 of the accessory 24, the four N poles (N) and S poles (S) of the four one end side magnets 13 (13a, 13b, 13c, 13d) are provided. The other end side magnets 14 (14a, 14b, 14c, 14d) are arranged so that the south pole (S) and the north pole (N) are opposed to each other, so that they are magnetically attracted to each other. Since each magnet is a metal magnet, it is strongly magnetically attracted and is not easily peeled off.

    Further, as described above, the tube 12 of the jewelry main body 11 can be easily twisted by 180 ° or more around the axis between both end portions along the longitudinal direction. The state of FIG. 10 in which the N pole (N) and the S pole (S) face each other naturally by the attractive force of each magnet even if the N poles (N) or the S poles (S) are opposed to each other.

    FIG. 15 is an enlarged view showing a mounting state using the stopper 41 following FIG. 14. One end side 36 of the accessory 24 that passes from above through the one through portion 45 of the S-shaped stopper 41 that is horizontally oriented is held from the periphery by the linear center portion 42 of the stopper 41 and the tip of the one end portion 43. The Therefore, the one end side 36 of the accessory 24 does not come off to the side. Further, the other end side 37 of the accessory 24 that passes from the upper side to the other passage portion 46 of the S-shaped stopper 41 that is turned sideways is formed by the linear center portion 42 of the stopper 41 and the tip of the other end portion 44. Retained from the surroundings. Therefore, the other end side 37 of the accessory 24 does not come off to the side.

    Also in this example, the accessory 24 that is stopped by using the S-shaped stopper 41 is in an attracted state due to the magnetic attractive force of the magnet, and is further detached in the circumferential direction by the holding force of the stopper 41. It is surely prevented. Therefore, there is no risk of loss due to unexpected dropout, and the anti-theft can be reliably prevented because it will not come off due to peeling off from the outside of the wearer. When the wearer removes the accessory 24 from the body, the accessory 24 is simply pulled out from the one end side 36 or the other end 37 of the accessory 24 from the through portions 45 and 46 of the stopper 41. Can be removed.

    FIG. 16 is a perspective view showing another example of the fastener of the accessory 24 according to the present embodiment. As shown in FIG. 16, the stopper 51 is formed by molding a metal, resin, or the like as a material, and is formed in a substantially eyeglass shape in a side view. That is, the frame body 52 of the stopper 51 has a “8” shape, and the one end side frame portion 53 has a circular shape with an inner diameter slightly larger than the outer diameter of the above-described accessory 24. Thereby, the circular space part in the one end side frame part 53 of the stopper 51 serves as one through part 55 through which the tip of the accessory 24 can pass.

    The other end side frame portion 54 of the stopper 51 is formed with a circular space portion similar to the one end side frame portion 53, and the inner diameter of the space portion is also slightly larger than the outer diameter of the accessory 24 described above. . Thereby, the circular space part in the other end side frame part 54 which the stopper 51 curved is the other through part 56 through which the tip of the accessory 24 can be passed.

    FIG. 17 is an explanatory view showing mounting using the stopper 51 shown in FIG. This attachment is to make it possible to more securely stop the accessory 24 around the neck by using the stopper 51 in contrast to the attachment of FIG. 7 described above.

Further, the other end 36 of the accessory 24 is passed through the other through portion 56 of the eyeglass-shaped stopper 51 as indicated by a right-pointing arrow.

    FIG. 18 is an enlarged view showing a mounting state using the stopper 51 following FIG. The one end side 36 of the accessory 24 that is passed through one through portion 55 of the eyeglass-shaped stopper 51 is held from the periphery by the through portion 55 of the one end side frame portion 53 of the eyeglass-shaped stopper 51. Therefore, the one end side 36 of the accessory 24 does not come off to the side. Further, the other end side 37 of the accessory 24 that is passed through the other through portion 56 of the eyeglass-shaped stopper 51 is held from the periphery by the other through portion 56 of the frame body 52 of the stopper 51. Therefore, the other end side 37 of the accessory 24 does not come off to the side.

    In this way, the accessory 24 stopped using the spectacle-shaped stopper 51 is attracted by the magnet's attractive magnetic force, and the holding power of the spectacle-shaped stopper 51 is shown in FIG. The separation in the circumferential direction is prevented more reliably than the stopper 41. Accordingly, there is no risk of loss due to unexpected dropout, and the anti-theft can be more reliably prevented since it will not come off due to peeling off from the outside of the wearer. When the wearer removes the accessory 24 from the body, the accessory 24 is simply pulled out in the axial direction from one end side 36 or the other end 37 of the accessory 24 from the through portions 55 and 56 of the stopper 51. Can be removed.

    FIG. 19 is an explanatory diagram showing attachment using the eyeglass-shaped stopper 51 shown in FIG. In this mounting process, the accessory 24 can be more securely stopped around the neck by using the eyeglass-shaped stopper 51 in contrast to the above-described mounting of FIG.

    As shown in FIG. 19, the wearer grasps one end side 36 and the other end side 37 of the accessory 24, winds the accessory 24 from the back of the neck to both sides, and connects both ends of the accessory 24 over the shoulder. Turn around the front of the neck. Then, the one end side 36 of the accessory 24 is passed through one through portion 55 of the eyeglass-shaped stopper 51 that is turned sideways as indicated by a downward arrow. Further, the other end side 36 of the accessory 24 is passed through the other through portion 56 of the eyeglass-shaped stopper 51 that is turned sideways as indicated by the downward arrow.

    FIG. 20 is an enlarged view showing wearing using the eyeglass-shaped stopper 51 following FIG. One end side 36 of the accessory 24 passed from above through the one through portion 55 of the spectacle-shaped stopper 51 that is turned sideways is held from the periphery by the one through portion 55 of the spectacle-shaped stopper 51. Therefore, the one end side 36 of the accessory 24 does not come off to the side. Further, the other end side 37 of the accessory 24 that is passed through the other through portion 56 of the eyeglass-shaped stopper 51 that is turned sideways is held from the periphery by the other through portion 56 of the stopper 51. Therefore, the other end side 37 of the accessory 24 does not come off to the side.

    Also in this example, the accessory 24 stopped using the spectacle-shaped stopper 51 is attracted by the magnet's attractive force, and in addition to the circumferential direction by the holding force of the spectacle-shaped stopper 51. Separation is more reliably prevented. Therefore, there is no risk of loss due to unexpected dropout, and the anti-theft can be reliably prevented because it will not come off due to peeling off from the outside of the wearer. When the wearer removes the accessory 24 from the body, the accessory 24 can be simply pulled out of the one end 36 or the other end 36 of the accessory 24 upward from the through portions 55 and 56 of the stopper 51. Can be removed.

    In this embodiment, the outer skin 25 is configured separately from the tube 12, but the outer skin 25 is processed on the surface portion of the tube 12, embedded in the surface portion of the tube 12, or bonded. Can be integrated into a single structure.

Further, the plurality of magnets 13, 14, 15 can be rotatable inside the tube 12. This can be achieved by making the inner diameter of the tube 12 somewhat larger than the outer diameter of the magnets 13, 14, 15. As described above, in the structure in which the magnets 13, 14, and 15 are rotatable inside the tube 12, the opposing magnets when the both ends of the tube 12 are overlapped have the same polarity of the N pole and the N pole. Even so, the magnet rotates due to the repulsive force acting between the same poles. By rotating in this way, the magnets facing each other become different polarities, and an attractive force acts. Thereby, since the jewelry main body 11 becomes a ring shape, the attachment to a body is attained.

[Second Embodiment]
FIG. 21 is an exploded perspective view showing the component structure of the accessory body of the accessory according to the second embodiment of the present invention. The jewelry main body 11 includes a single string-like tube 12 having both ends open, a plurality of magnets 63 inserted into the tube 12, and a plurality of magnets 63 inserted alternately into the tube 12. The spacer 65, one end side cap 16 for closing the one end side opening 68 of the tube 12, and the other end side cap 17 for closing the other end side opening 19 of the tube 12.

    The magnets 63 are configured in a cylindrical shape having the same diameter and length, and are inserted over the entire length in the tube 12. When the magnet 63 is inserted into the tube 12, the central portion of the circular tube of the tube 12 and the central portion of the one end side magnet 63 are aligned. The one end side magnets 63 are inserted in a series arrangement along the length direction of the tube 12 so that the end portions in the axial direction face each other. As the magnet 63, a metal magnet having a strong attractive force (for example, 2000 gauss), for example, a ferrite magnet is used. These magnets 63... Generate a mutual attractive force at the portion where the one end side opening 68 and the other end side opening 69 of the tube 12 overlap or intersect when the tube 12 is wound around the user's neck. To be.

    When the magnets 63 are arranged around the user's neck and do not function as stopping means for the tube 12, a strong attractive force is not necessarily required.

    The spacers 65, for example, are inserted alternately into the tube 12 one by one with the magnets 63, and these spacers 65, like the magnets 63, have a cylindrical shape with the same diameter and length. 12 are inserted in a series arrangement in which the axial end portions thereof face each other along the length direction in 12.

    Various materials such as a magnetic material and a non-magnetic material can be applied to the spacer 65. For example, as the material of the spacer 65, other iron-based metals such as iron and stainless steel can be applied. In this case, the magnetic lines of force in the length direction of the magnets 63 are improved. Further, as the material of the spacers 65, non-ferrous metals other than ferrous metals, such as titanium, can be applied. Further, a noble metal such as gold or silver can be applied to the spacer 65. When these noble metals are applied, luxury, feeling of weight, etc. can be obtained. Further, for example, precious stones such as hematite can be applied. When precious stones are applied, the feeling of use can be increased.

    FIG. 22 is an overall cross-sectional view showing a state where the components shown in FIG. 21 are assembled as the accessory main body 61. As shown in FIG. 22, a plurality of magnets 63 and spacers 65 on one end side are alternately inserted in series in the one end side opening 18 of the tube 12, and the tube 12 A plurality of other end side magnets 63 and spacers 65 are alternately inserted in the other end side opening 19 one by one in series. Further, a plurality of intermediate magnets 63,... Are also provided in a portion other than the one end side opening 18 and the other end side opening 19 in which the magnets 63 and the spacers 65 are inserted in the tube 12. The spacers 65 are alternately inserted in series one by one. Thus, the magnets 63 and the spacers 65 are alternately arranged in series one by one over the entire length direction of the tube 12. However, it is not always necessary that the magnets 63 and the spacers 65 are alternately arranged in series one by one. For example, two magnets 63 and one spacer 65 are alternately arranged, or any other arbitrary number. Can also be arranged.

    If the axial end surfaces of the magnet 63 on the one end side, the magnet 63 on the other end side, and the magnet 63 on the other end side are inserted in close contact with each other, there is no space for tilting these end surfaces, and consequently The tube 12 cannot be bent. Therefore, there are predetermined gaps between the magnets 63 at one end side, between the magnets 63 at the other end side, between these and the intermediate magnet 63, and between the intermediate magnets 63, respectively. Thus, the magnet 63 at one end, the magnet 63 at the other end, and the magnet 63 at the other end can be inclined with respect to each other, so that the tube 12 can be bent.

    The one end side opening portion 18 and the other end side opening portion 19 of the tube 12 are respectively closed by the one end side cap 16 and the other end side cap 17 and are fixed by adhesion or a screw structure or the like. This prevents the one end side magnets 16 and the other end side magnets 63 and the other end side magnets 63 from falling off from the one end side cap 16 and the other end side cap 17 of the tube 12.

    According to the present embodiment, various functions can be obtained by adopting a configuration in which the spacers 65 are inserted into the tube 12 alternately with the magnets 63. That is, as described above, when other ferrous metals such as iron and stainless steel are applied to the spacers 65, the magnetic lines of force in the length direction of the magnets 63 can be improved. Further, when a non-ferrous metal other than the ferrous metal, such as titanium, is applied as the material of the spacer 65, a high-class feeling can be obtained. Further, when a noble metal such as gold or silver is applied to the spacer 65, luxury and weight can be obtained. Furthermore, when a precious stone such as hematite is applied, the feeling of use can be increased.

  Also in this embodiment, the magnet 63 can be rotated inside the tube 12. As described above, in the structure in which the magnet 63 is rotatable inside the tube 12, even if the opposite magnets when the both ends of the tube 12 are overlapped have the same polarity of the N pole and the N pole, the same The magnet rotates due to the repulsive force acting between the poles. By rotating in this way, the magnets facing each other become different polarities, and an attractive force acts. Thereby, since the jewelry main body 11 becomes a ring shape, the attachment to a body is attained. In this case, the spacer 65 can be rotated in the tube 12.

[Third Embodiment]
FIG. 23 is an exploded perspective view showing the component structure of the accessory body of the accessory according to the third embodiment of the present invention. The accessory main body 11 of this embodiment includes a single string-like tube 12 having both ends opened, a plurality of magnets 63 inserted on one end side and the other end side in the tube 12, A plurality of spacers 65 inserted in an intermediate portion other than the end portion, one end side cap 16 for closing the one end side opening 18 of the tube 12, and the other end side cap 17 for closing the other end side opening 19 of the tube 12. It is comprised by.

    The magnets 63 are configured in a cylindrical shape having the same diameter and length, and are arranged adjacent to a predetermined number of one end side and the other end side in the length direction in the tube 12. . When these magnets 63 are inserted into the tube 12, the center part of the circular tube of the tube 12 and the center part of the magnets 63 are in a state of matching. Further, the magnets 63 are inserted in a series arrangement along the length direction of the tube 12 so that axial end portions thereof face each other.

    The spacers 65 are arranged in portions other than the portion where the magnets 63 are arranged in the tube 12, that is, in an intermediate portion excluding one end side and the other end side. These spacers 65, like the magnets 63, are also cylindrical in shape with the same diameter and length, and are inserted in a series arrangement along the length direction in the tube 12 with their axial ends facing each other. The Various materials such as a magnetic material and a non-magnetic material similar to those of the second embodiment can be applied to the spacer 65. Therefore, as the material of the spacer 65, other ferrous metals such as iron and stainless steel, non-ferrous metals such as titanium, precious metals such as gold and silver, and precious stones such as hematite can be applied.

    FIG. 24 is an overall cross-sectional view showing a state in which the components shown in FIG. As shown in FIG. 24, a plurality of magnets 63 at one end side are inserted into the one end side opening 18 of the tube 12 in series, and a plurality of magnets 63 are also inserted into the other end side opening 19 of the tube 12. Of magnets 63 are inserted in series. Also, a plurality of spacers 65 are inserted in series in a portion other than the one end side opening 18 and the other end side opening 19 in the tube 12, that is, in the middle portion.

    If the axial end surfaces of the magnet 63 on the one end side, the magnet 63 on the other end side, and the spacer 65 on the intermediate side are inserted in close contact with each other, there is no space for tilting these end surfaces, and consequently The tube 12 cannot be bent. Therefore, there are predetermined gaps between the magnets 63 at one end side, between the magnets 63 at the other end side, between these and the intermediate spacer 65, and between the intermediate spacers 65, respectively. Thus, the magnet 63 on one end side, the magnet 63 on the other end side, and the spacer 65 on the intermediate side can be inclined with respect to each other, so that the tube 12 can be bent.

    According to the present embodiment, since the predetermined number of magnets 63 are arranged on one end side and the other end side of the tube 12, the end portions of the tube 12 can be magnetically attracted to each other.

  Also in this embodiment, the magnet 63 can be rotated inside the tube 12. As described above, in the structure in which the magnet 63 is rotatable inside the tube 12, even if the opposite magnets when the both ends of the tube 12 are overlapped have the same polarity of the N pole and the N pole, the same The magnet rotates due to the repulsive force acting between the poles. By rotating in this way, the magnets facing each other become different polarities, and an attractive force acts. Thereby, since the jewelry main body 11 becomes a ring shape, the attachment to a body is attained. In addition to the magnet 63, the spacer 65 may be rotatable in the tube 112.

    FIG. 34 is an explanatory view showing, in an enlarged manner, a stopped state of the accessory. The outer cap 27 on one end side of the accessory 24 and the outer cap 26 on the other end side approach each other in a state where the one end side and the other end side are aligned in parallel from a staggered direction and become a superposed state. The stopper 540 rotates around the hinge shaft 543 and closes to each other. The stopper pin 549 and the pin receiver 557 are coupled to each other and are locked by the large-diameter head 551. The one end side and the other end side of the accessory 24 are held by the one end side stopper 552 and the other end side stopper 553, respectively.

    FIG. 35 is an explanatory diagram showing a usage state of the stopper 540. The accessory 24 is attached around the neck 34 of the wearer 33, and one end side and the other end side of the accessory 24 are overlapped behind the neck 34 and locked by magnetic force.

    First, the wearer 33 grips one end side of the accessory 24 with one hand (right hand) and the other end side of the accessory 24 with the other hand (left hand). Then, the accessory 24 is gradually lifted upward from the front lower side (submandibular) of the neck 34 of the wearer 33, and both ends of the accessory 24 are turned to the rear of the neck 34 through the upper part of the shoulder 35. Thereafter, one end side and the other end side of the accessory 24 are polymerized.

    Then, as soon as the one end side and the other end side of the accessory 24 are moved to positions close to each other by a certain distance, they are immediately attracted to each other by the attractive force. That is, the wearer 33 is easily and quickly mounted and fixed by a strong magnetic force simply by bringing the one end side and the other end side of the accessory 24 close to the back of the neck 34. In this state, as shown in FIG. 10, one end side and the other end side of the accessory 24 are fixed by the stopper 540. As a result, the accessory 24 can be easily mounted and fixed by the detachable five stoppers 40, and the mounted state becomes strong, and there is no possibility of dropping off due to peeling or the like.

    FIG. 36 is a partial cross-sectional view showing, in an enlarged manner, the overlapping portion on the rear side of the neck 34 between the one end side and the other end side of the accessory 24. For example, four one end side magnets 13 (13a, 13b, 13c, 13d) from the one end side outer cap 26 side are provided in the accessory main body 11 at one end side in the overlapping portion between the one end side and the other end side of the accessory 24. They are arranged in series. As described above, these magnets 13 (13a, 13b, 13c, 13d) are each formed in a columnar shape, and each of the magnets 13 (13a, 13b, 13c, 13d) has an N pole (N) and an S pole ( S) is arranged on the outer peripheral surfaces on the opposite sides of the cylinder. The N poles (N) and S poles (S) of the magnets 13 (13a, 13b, 13c, 13d) that are adjacent to each other are arranged in a staggered direction. Specifically, the N pole (N) is directed downward and the S pole (S) is directed upward of the one end side magnet 13a arranged at the end portion closest to the one end side outer cap 26 side of the accessory 24. The N pole (N) of the one end side magnet 13b arranged second from the end side adjacent to the one end side magnet 13a is upward, and the S pole (S) is downward. Further, the third one end side magnet 13c from the end side adjacent to the one end side magnet 13b has a north pole (N) facing down and a south pole (S) facing up, contrary to the second end magnet 13b. It has become. The one end side magnet 13d arranged fourth from the end side adjacent to the one end side magnet 13c is opposite to the third one end side magnet 13c, and the N pole (N) faces upward and the S pole (S) faces downward. It has become. Similarly to the above, the subsequent intermediate magnet 15 has N poles (N) and S poles (S) arranged in alternate directions.

    On the other hand, in the overlapping portion between the one end side and the other end side of the accessory 24, the other end side outer cap 27 side has, for example, four other end magnets 14 (14a, 14b, 14c, 14d) are arranged in series. As described above, these magnets 14 (14a, 14b, 14c, 14d) are each formed in a columnar shape, and each magnet 14 (14a, 14b, 14c, 14d) has an N pole (N) and an S pole ( S) is arranged on the outer peripheral surfaces on the opposite sides of the cylinder. The magnets 14 (14a, 14b, 14c, 14d) adjacent to each other have N poles (N) and S poles (S) arranged in alternate directions.

    Specifically, the N pole (N) of the other end side magnet 14a disposed closest to the other end side outer cap 27 side of the accessory 24 is facing upward, and the S pole (S) is facing downward. It has become. In the other end side magnet 14b arranged second from the end side adjacent to the other end side magnet 14a, the N pole (N) faces downward and the S pole (S) faces upward, contrary to the above. In addition, the other end side magnet 14c arranged third from the end side adjacent to the other end side magnet 14b is further opposite to the second other end side magnet 14b. The pole (S) is facing down. Furthermore, the other end side magnet 14d arranged fourth from the end side adjacent to the other end side magnet 14c is further opposite to the third other end side magnet 14c, and the N pole (N) faces downward. The south pole (S) is facing upward. As for the intermediate magnet 15 that follows, the north pole (N) and the south pole (S) are arranged in alternate directions as described above.

    Accordingly, in the overlapping portion between the one end side and the other end side of the accessory 24, the N pole (N) and S pole (S) of the four one end side magnets 13 (13a, 13b, 13c, 13d), and the other four The end-side magnets 14 (14a, 14b, 14c, 14d) are arranged so that the south pole (S) and the north pole (N) are opposed to each other, so that they are magnetically attracted to each other. Since each magnet is a metal magnet, it is strongly magnetically attracted and is not easily peeled off.

    Further, as described above, the tube 12 of the accessory body 11 can be easily twisted by 180 ° or more around the axis between both ends along the longitudinal direction. Even if the N poles (N) or the S poles (S) face each other immediately after being wound around, the N pole (N) and the S pole (S) are naturally formed by the attractive force of each magnet. It is in a state of facing each other. For this reason, it is not necessary for the wearer to manually rotate the accessory 24 and the wearer can easily wear it around the neck.

[Second example of stopper]
FIG. 37 shows a stopper 570 of the second example. The stopper 570 of the second example is formed or bent using a metal, resin, or the like as a material, and is formed in an approximately S shape in a side view. That is, the central portion 571 of the stopper 570 is substantially linear, and the one end 572 is curved in a circular shape with an inner diameter slightly larger than the outer diameter of the accessory 24. A gap smaller than the outer diameter of the accessory 24 is formed between the linear center portion 571 of the stopper 570 and the tip of the one end portion 572. As a result, the circular space in the curved one end 572 of the stopper 570 serves as one through portion 575 through which the tip of the accessory 24 can pass.

    The other end portion 573 of the stopper 570 is curved in a circular shape in the opposite direction to the one end portion 572, and the inner diameter of the curved portion is also slightly larger than the outer diameter of the accessory 24 described above. A gap smaller than the outer diameter of the accessory 24 is also formed between the linear central portion 571 of the stopper 570 and the tip of the other end 543. Thus, the circular space portion in the other end 573 curved of the stopper 570 is the other through portion 546 through which the tip of the accessory 24 can pass.

    Further, a magnet 576 is provided on one end side 572 of the stopper 570, and the one end side of the accessory 24 can be attracted by the magnetic force of the magnet 576. A magnet 577 is also provided on the other end side of the stopper 570, and the other end side of the accessory 24 can be attracted by the magnetic force of the magnet 577.

    In this stopper 570, the accessory 24 is attached around the neck 34 of the wearer 33, and one end side and the other end side of the accessory 24 are superposed on the rear side of the neck 34 and locked by a magnetic force, thereby fixing the accessory 24 to the neck. You can stop more reliably around.

    That is, the wearer grasps one end side and the other end side of the accessory 24, lifts the accessory 24 upward from the lower front side of the neck, and turns both ends of the accessory 24 rearward of the neck via the upper shoulder. Then, one end side of the accessory 24 is passed through one through portion 574 of the S-shaped stopper 570. Further, the other end side of the accessory 24 is passed through the other through portion 575 of the S-shaped stopper 570 as indicated by a right-pointing arrow. Thus, one end side of the accessory 24 that has passed through the one S-shaped through portion 575 is held from the periphery by the linear center portion 571 and the tip end of the one end portion 572 of the stopper 570. Therefore, the one end side of the accessory 24 does not come off to the side. In addition, the other end side of the accessory 24 that is passed through the other through portion 575 of the S-shaped stopper 570 is held from the periphery by the linear center portion 571 and the distal end of the other end portion 573 of the stopper 570. . Therefore, the other end side of the accessory 24 does not come off to the side.

    In this way, the accessory 24 that is stopped by using the S-shaped stopper 570 is brought into an attracted state by the magnetic attractive force of the magnet, and further, the retaining force of the stopper 570 can further prevent the separation in the circumferential direction. . Therefore, there is no risk of loss due to unexpected dropout, and the anti-theft can be reliably prevented because it will not come off due to peeling off from the outside of the wearer. When the wearer removes the accessory 24 from the body, the accessory 24 can be easily removed simply by pulling one end or the other end of the accessory 24 in the axial direction from the through portions 574 and 575 of the stopper 570. be able to.

[Third example of stopper]
FIG. 38 is a perspective view showing the stopper 81 of the third example. The stopper 81 of the third example is formed by molding a metal or resin as a raw material, and is generally formed in an eyeglass shape (“8” shape) as viewed from the side. In other words, the stopper 81 has a cylindrical one end portion 83 and the other end portion 84 connected together via the body portion 82 to constitute a spectacle-shaped outer frame.

    Inside the cylindrical one end portion 83, one space (through portion) 85 through which the one end side of the accessory 24 and the outer cap 26 pass is formed, and the diameter of this one space 85 is the one end side of the accessory 24 and The diameter is larger than that of the outer cap 26. Thereby, the one end side of the accessory 24 can be freely inserted into or extracted from the cylindrical one end portion 83. Further, the space 86 of the cylindrical other end portion 84 has substantially the same diameter as the one end portion 83.

    An inner ring 91 is inserted into the cylindrical end portion 83 of the stopper 81. The inner ring 91 is movable along the direction in which the accessories 24 overlap each other inside the cylindrical one end portion 83, and by a push screw 92 inserted into a screw hole 93 provided in the cylindrical one end portion 83. The jewelry can be moved by being pushed in the overlapping direction. An internal ring 94 is also inserted into the space 86 of the cylindrical other end 84. The inner ring 94 is also movable in the direction in which the accessories are overlapped with each other inside the cylindrical other end portion 84, and is pressed by a push screw 95 inserted into a screw hole 96 provided in the cylindrical other end portion 84. It is possible to move in the direction in which the accessories are moved. A compression coil spring 97 is interposed between the inner rings 91 and 94, and the compression coil spring 9 normally causes the inner rings 91 and 94 to be elastically separated in directions opposite to each other.
