Description

  The present invention relates to a fastener and an annular accessory equipped with the same, and more particularly to a fastener for connecting both ends of a main body of a bracelet, anklet, necklace or the like into an annular shape when worn on the body, and an annular accessory equipped with the same. .

  Ring accessories such as bracelets, anklets, necklaces, chokers, etc. are provided with a pair of fasteners such as a pair of fasteners on both ends of the main body, which are the open ends, and the ends are connected to each other as an annular body of a predetermined size. What is worn is common. However, such fasteners have extremely small screws and hooks and are complicated in shape, so that the attachment / detachment work is often troublesome, and it is not easy for a user whose hand does not move skillfully. In addition, these fasteners cannot change the size of the accessory (the diameter of the annular body), or even if it can be changed, only a very small range can be changed, or it is troublesome work, and compatibility in terms of size Was not enough.

  On the other hand, there is also known an annular accessory that uses a ring or the like that has a C-shape or a coil shape and has elastic restoring force as a core material. Those that are reduced in diameter by a restoring force and are worn on the body have been put into practical use. For example, a so-called magnetic health bracelet in which spheres made of permanent magnets are provided at two open ends of a C-shaped ring made of steel wire and an anklet made of a spiral elastic decorative body are known.

  Furthermore, Japanese Patent Application Laid-Open No. 2004-166895 presents a decorative body in which a plurality of permanent magnets are inserted into a ring having a C-shaped elastic restoring force so as to be equally spaced from each other and stoppers are provided at both ends. In actual No. 3042173, a plurality of permanent magnets and spacers are alternately inserted into an elastic wire shaped like a coil, and the side surfaces of the permanent magnets arranged in the circumferential direction are attached to each other. And what is maintained is shown. These can be attached and detached relatively easily without using complicated fasteners by expanding and reducing the diameter by the elastic restoring force of the ring-shaped or coil-shaped wire, and within a predetermined range. It is also possible to respond to the size change. In addition, by using the permanent magnet as a decorative body, it is possible to expect some health enhancement effects such as improvement of blood flow of the body by magnetic action in addition to the decorative properties.

However, in the case of considering a case where a single piece of an accessory having an elastic wire body having a predetermined shape with an elastic restoring force is shared by each wearing part of a body having various cross-sectional shapes and sizes For example, it is difficult to use a bracelet as an anklet having a larger diameter than that, and it is more difficult to use the bracelet for a necklace having a larger diameter. In addition, since the cross-sectional shape and thickness of the wearing part varies from user to user, the accessory does not fit the wearing part, so there is a gap, or conversely, it is tightened too much. It is difficult to realize the wearability and aesthetics of the person and the wearing site.
JP 2004-166895 A JITTO No.3042173

  The present invention is intended to solve the above-described problems. In addition to facilitating the attachment and detachment of the annular accessory to the body, it is possible to easily attach the attachment parts having various cross-sectional shapes and sizes with one annular accessory. It is an object to make it possible to realize excellent wearability and aesthetics.

  Therefore, the present invention provides a fastener for an annular accessory that is attached to the body as an annular body by connecting both ends of the main body to each other. A plurality of columnar bodies made of permanent magnets having insertion holes penetrating through both end faces and having opposite polarities are inserted freely so that the opposing end face sides have the same polarity, and the end side The columnar bodies adjacent to each other are formed in a set of linear locking portions that can be bent and deformed within a predetermined range while maintaining substantially the same distance by magnetic repulsion. By arranging the set of linear locking portions in parallel, the side surfaces of the columnar bodies having different polarities are adsorbed to each other, and the parallel portions are locked to form an annular body as a whole.

  In this way, a plurality of permanent magnets are inserted into a pair of linear locking portions that can be bent and deformed, so that side surfaces with different polarities can be attracted and locked in parallel. Can be easily attached to the body, and can be easily removed by pulling apart the parallel portions of the linear locking portions against the adsorption force, and the diameter of each columnar body is multi-stage. Can be adjusted. In addition, since the linear locking portion is not an elastic member having a shape, but a string-like core material, it is easily deformed along the cross-sectional shape of the body-mounted portion and easily adheres. It should be noted that the magnetic poles are concentrated in the centrifugal direction from the interval portion by arranging the columnar bodies so that the end faces of the same pole face each other, and when these are arranged in parallel, the strong magnetic lines of force further spread in the centrifugal direction. In addition, the effect of magnetic lines of force on the mounting portion is also strong.

  Further, in this fastener for an annular ornament, the columnar body to be used is opened so that the opening portion of the insertion hole opened in the end surface showing the predetermined polarity has a larger diameter than the opening portion of the end surface showing the other polarity. If it is possible to determine the polarity of each end face by the size of the diameter of the part, it is easy to determine the orientation when inserting the columnar body through the string-like core material, and the creation work of the fastener is easy It becomes.

  Furthermore, in the above-described ring accessory fastener, if the decorative body having the insertion hole is inserted into a part or all of the interval formed by the adjacent columnar bodies, the aesthetics of the fastener itself can be obtained. Can be improved.

  Furthermore, if it provides as an annular accessory provided with the fastener mentioned above, it will become easy to obtain each effect | action mentioned above, However, The annular accessory is in the state in which at least one of the linear latching | locking parts is a latching state. Adjusting the diameter of the annular body from the thickness of the wrist to the thickness of the ankle to have a length that can be accommodated, and if it can be used at least as a bracelet and an anklet, it can be used as two or more kinds of annular accessories It becomes available.

  In addition, the above-mentioned annular accessory has a length that can be adjusted by adjusting the diameter of the annular body with at least one of the linear locking portions locked to at least the thickness of the neck, and can be used as at least a necklace or a choker. If it is, it will be more versatile.

  In addition, if the above-mentioned annular accessory is composed entirely of a linear locking portion, the columnar body forming the linear locking portion constitutes an ornament throughout and exhibits an excellent aesthetic appearance. In addition, the appearance fixed to the body so as to wrap around has a characteristic aesthetic appearance, and the overlapped parallel portion also becomes an accent on the design.

  According to the present invention comprising a plurality of columnar bodies and a pair of linear locking portions locked to each other by magnetic attraction thereof, it is possible to extremely easily attach and detach the annular accessory to the body, In addition, the linear locking portion can be deformed in a curved manner and the diameter can be changed in multiple stages, so that it can easily correspond to mounting sections of various cross-sectional shapes and sizes, and has excellent mounting properties and An aesthetic can be realized.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  First, with reference to FIGS. 1 to 3, a basic configuration and operation of the fastener for the annular accessory according to the present invention will be described. Referring to the partial plan view of the fastener 2A shown in FIG. 1, the fastener 2A is connected to the wires 5A and 5A as string-like cores extending from both ends of the main body of the annular accessory (not shown) and the center of the columnar member. A columnar body 4 having insertion holes 41 (see FIG. 2) passing through both end surfaces along the axis includes linear locking portions 3A and 3A each inserted by a predetermined number so as to be freely movable.

  Referring to FIG. 2 (A) showing an enlarged partial longitudinal sectional view of the linear locking portion 3A, the columnar body 4 is magnetized in the direction along the central axis thereof, and one end surface side is N pole, and the other end surface. It consists of a permanent magnet whose side is the south pole. The type of permanent magnet is not particularly limited, but a general neodymium magnet may be used from the viewpoint of ease of processing and cost, and gloss such as nickel plating or gold plating from the viewpoint of aesthetics, durability, and non-irritating body. It is recommended to have a relatively stable surface treatment. In addition, by using a cylindrical permanent magnet in this way, even if the insertion hole penetrates the central axis portion, the decrease in magnetic force is relatively small, and the attraction force during mounting and fixing and the magnetic force on the body It is easy to ensure the action.

  And after inserting a predetermined number of the columnar bodies 4 while alternately changing the direction so that the end faces showing the same pole face each other, the end side is in a state in which it cannot be removed with the caulking metal fitting 51 provided on the wire 5A, Adjacent columnar bodies 4 and 4 that are inherently free to move are magnetically repelled by being close to each other at a predetermined distance to maintain a substantially equal interval. In this manner, the plurality of columnar bodies 4 repel each other with an appropriate interval, so that the linear locking portion 3A can be freely deformed and the curve at the time of bending becomes smooth, and the mounting site It is easy to fit in the shape of this and also has an excellent aesthetic appearance when worn.

  Referring to the enlarged partial longitudinal sectional view showing the state of the linear locking portions 3A and 3A when the fastener 2A is fixed in FIG. 2B, the linear locking portions 3A and 3A are arranged in parallel to face each other. By making them close to each other, the ends of the columnar bodies 4 and 4 that are arranged side by side are adsorbed to each other, and the side surfaces of the portions are in close contact with and locked to each other. As shown in FIGS. 3A, 3B, and 3C for explaining the fixing method using the linear locking portions 3A, 3A, the parallel portions where the linear locking portions 3A, 3A overlap each other are as follows. From the relationship of the polarity combinations of the columnar bodies 4 and 4 arranged side by side, one, three, five, seven, etc., in which the combination of the columnar bodies 4 and 4 arranged in parallel at every other pitch is used when adjusting the size.・ It can be implemented in multiple stages in odd units.

  Further, since the linear locking portions 3A and 3A can be bent and deformed within a predetermined range, the parallel portion can be deformed to some extent in accordance with the mounting portion, and the mounting property is extremely excellent. Furthermore, when removing the annular accessory, the respective locking portions 3A, 3A can be held with their fingers, and can be released from the locked state relatively easily by pulling them apart against the attractive force. .

  As shown in FIG. 2A, the insertion hole 41 penetrating the columnar body 4 includes a small diameter portion 41a having a diameter slightly larger than that of the wire 5A and a large diameter portion 41b having a diameter larger than that. The large-diameter portion 41b opens at the end face on the S pole side. Thereby, it becomes possible to know the direction of the polarity only by looking at the diameter of the opening on the end face, making it easy to create the fastener 2A. Further, since the large-diameter portion 41b is provided, when the crimping metal fitting 51 is provided on the distal end side of the wire 5A as shown in the drawing, if it is arranged in the direction in which it is accommodated, the appearance of the annular accessory can be improved without being exposed. It will not be damaged.

  Further, the cord-like core material is not limited to a thin steel wire twisted like the wire 5A, and other materials may be used as long as they have predetermined durability, strength, and flexibility. In addition, in the present invention, the columnar bodies 4 repel each other and maintain a predetermined interval, so that the cord-shaped core material and the insertion holes 41 of the columnar bodies 4 are not easily rubbed. Another advantage is that there is little occurrence of wear and wear of the string-like core material.

  Next, a specific embodiment of the annular accessory using the fastener having the above-described configuration will be described below with reference to FIGS.

  FIG. 4 shows an annular accessory 1B that can also serve as a bracelet and an anklet according to the first embodiment of the present invention. The annular accessory 1B is obtained by extending a fastener 2B having the same configuration as the above-described fastener 2A from both ends of a decorative body 60 made of a slightly curved metal piece. When this annular accessory 1B is attached to the body, the diameter suitable for attachment to the wrist is obtained if the number of the columnar bodies 4 in the parallel portion is a large number of five or more as in FIG. 3C. Similarly to B), if the number of the columnar bodies 4 in the parallel portion is a small number of 3 sets or less, the diameter is suitable for attachment to the ankle. The annular accessory 1B having such a configuration can share two types of bracelet and anklet with one, and in addition to being easy to attach and detach, the size adjustment is also extremely easy.

  FIG. 5 shows an annular accessory 1C that can be used as a necklace or a choker according to the second embodiment of the present invention. In the annular accessory 1C, the fasteners 2C similar to the fasteners 2A described above are provided on both ends of the chain 70. In this case as well, the point that the attachment / detachment is easy and the size adjustment is easy is the same as described above. However, the present embodiment is characterized in that the fastener 2C itself also serves as a decorative body of the annular accessory 1C. . In other words, the columnar body 4 that has been surface-treated with nickel plating that is inexpensive and excellent in gloss, or gold plating that gives a gorgeous impression, exhibits a visual effect similar to that of jewelry, and the overlapping of the linear locking portions 3C and 3C. The parallel part is an accent on the design.

  6 to 8 show an annular accessory 1D that can also serve as a bracelet, anklet, necklace, and choker according to a third embodiment of the present invention. Unlike the embodiment described above, the annular accessory 1D is characterized in that the entire accessory is composed only of the fastener 2D and does not have any other decorative body. For example, a user having a general physique uses a length of about 50 cm, and a plurality of columnar bodies 4 are inserted through the wire 5D and continuously provided over the entire length. .

  Then, referring to FIG. 7, which is a perspective view showing a use state of the annular accessory 1D as a bracelet, the annular accessory 1D is locked and fixed in a coiled state around the wrist indicated by the alternate long and short dash line. There are parallel parts and triple parallel parts. Further, since the parallel columnar bodies 4 are adsorbed to each other, the fixing force to the wrist is firm, so that the columnar bodies 4 do not fall off even with intense movement. In addition, it looks like a snake as a whole, and is also characteristic as a bracelet design.

  FIGS. 8A, 8B, and 8C are views for explaining a state in which the annular accessory 1D is attached to the wrist, ankle, and neck, and broken lines indicate cross-sectional shapes of various parts of the body. As shown in the figure, the annular accessory 1D can correspond to various diameter sizes, and is mounted along the cross-sectional shape of each part of the body, and exhibits excellent wearability. Since the annular accessory 1D is continuously provided with the columnar bodies made of permanent magnets over the entire length as described above, an excellent health promotion effect by magnetic action can be expected. In particular, since the end faces of the opposing columnar bodies 4 and 4 have the same polarity, the lines of magnetic force are strongly spread to the outside, and the presence of overlapping parallel portions can be expected to have a larger magnetic action.

  That is, FIG. 10A is a diagram for comparing the range in which the magnetic force is equal to or greater than a predetermined strength by bringing an object equipped with a permanent magnet close to a magnetic field viewing device in which a powdered magnetic material is diffused and enclosed in a fluid. ), (B), (C), a conventional decorative body in which a plurality of columnar bodies 4 shown in (A) are arranged so that the polarities are in the same direction, and a spacer made of a non-magnetic material is interposed therebetween. In the book, the range of the predetermined strength or more is limited to a narrow range indicated by hatching and hardly spreads in the centrifugal direction, whereas the plurality of columnar bodies 4 shown in (B) are arranged so that the polarities are alternately different. In the decorative body according to the invention, a range of a predetermined strength or more is expanded in the centrifugal direction, and when the decorative body of the present invention of (B) shown in (C) is arranged in parallel, the range showing the predetermined strength or more is further in the centrifugal direction. It is because it spread to.

  In addition, as shown in FIG. 9 (A), a bead-shaped decorative body 80 with an insertion hole penetrating between the adjacent columnar bodies 4 and 4 in all the embodiments described above is appropriately used. By arranging, it can be made more excellent in aesthetics. And if the decoration body 80 shall be arrange | positioned in the part which the large diameter part 41b of the penetration hole 41 opposes, as shown to FIG. 9 (B), the accommodation will become good.
