DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to accessories such as necklaces and bracelets to be hung on a neck or arm.

[0002]

2. Description of the Related Art A necklace of a typical accessory which is widely used generally has a main part formed by a cascade of decorative bodies such as pearls or the like through a single core wire. It has a basic form in which both ends of the body are connected and locked to form an annular body, and the body is hung and worn on the neck. As for the core wire, those using a flexible yarn such as a silk thread or a shape memory alloy wire disclosed in JP-A-2000-106923 are widely used. "It is configured in a flat mounting form in which it hangs down by gravity in contact with the wearer's bare skin or clothing surface.

[0003] The ends of the beads are penetrated through the decorations at both ends of the beads as shown in Japanese Utility Model Registration No. 3014576. A connecting means for connecting to form a ring is employed.

[0004]

Since the above-mentioned conventional necklace is of the above-mentioned flat mounting type, when worn on bare skin like a summer or an athlete, the necklace adapts to the bare skin and each of the decorative body groups Is in direct contact with the skin and hangs down, so that sweat and skin dirt adheres and blocks the sweat, causing a "stickiness",
There is a problem that a decorative body such as a pearl becomes dark and impairs aesthetic appearance. The necklace in a worn state lacks a three-dimensional effect because it is viewed two-dimensionally, so that it tends to have a monotonous aesthetic and thus lacks an aesthetic appearance.

[0005] In addition, since the above-mentioned reams cannot be expanded or contracted in the lengthwise direction, there are cases where the beads cannot be easily stretched and worn when worn around the neck. For example, when a strong infant is subjected to a strong external force such as pulling, the core wire may be elongated and become defective in shape, or may be broken and broken, and the striated body may be impacted by the strong pull. Necklaces may cut into the neck and damage the skin.

Further, if the core wire is made of a wire made of a highly rigid material such as a shape memory alloy wire such as a Ni (nickel) -Ti (titanium) alloy wire in the above-mentioned annular connecting means of a conventional necklace, It is difficult to form and weld the ring part and braze and weld it to the piece-shaped locking device that keeps the decorative body group from falling out.
There is a difficulty in processing that makes it difficult to take measures to connect the cascading rings.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art and to provide an ornament for further improving the aesthetic quality and an end locking structure of the ornament.

[0008]

SUMMARY OF THE INVENTION The present invention, which achieves the above object, provides a jewelry comprising, as a main part, a continuum in which a group of jewels is inserted into a single core wire, wherein the core wire has a helical coil portion. Or it consists of a shape memory line with a corrugated part,
In the state of being attached to the human body, an accessory that is characterized by a structure configured to be able to maintain the shape of the helical coil portion or the waveform portion,

[0009] The end of a jewelry ornament, in which a group of jewels is inserted through a single rigid core wire, has a retaining structure for retaining the ornamental group, and the end of the rigid core wire is A flexible wire having connection rings at both ends of the beads is overlapped and set in a through hole of a piece-shaped locking member, and the rigid core wire and the flexible wire of the overlapped set are press-fit pins or screws. The end locking structure of the accessory is characterized by a structure of a rigid-flexible material set lock structure pressed and fixed by pins.

[0010] That is, in the ornament of the present invention having the above-mentioned structure, the continuous body forming the main part is changed from the conventional monotonous straight curve form to the three-dimensional form or continuous wave form with respect to the wearing surface by the helical coil part or the corrugated part. Form "wearing configuration,
In addition, it is characterized by a structure constituted by an elastic bead which can be easily elastically expanded and contracted by a stretching external force. The jewels as constituents of the present invention mean "jewels and imitations thereof" of the Trademark Law and metal or non-metal ornaments.
Then, a mode is adopted in which the core wire is a Ni-Ti alloy wire, the surface is a gray color or an aluminum coating surface, or the locking structure at both ends of the bead is the end locking structure of the present invention.

On the other hand, the end locking structure of the accessory according to the present invention having the above-mentioned structure is formed by forming the above-mentioned rigid and flexible material into an overlapped lock form, so that the flexible wire is "spring washer at the nut tightening lock portion of the machine element". ), And function as a cushioning material between the locked rigid objects to further improve and stabilize the locking force, and the flexible wire is made of cotton yarn. A rope material or a single wire material in which silk, metal, or non-metallic yarns are twisted is used. In order to further improve the locking and fixing force, a resin coating containing metal powder is provided on the outer periphery of the rope material, or visually recognized. There is a case where a rope body having a twisted configuration is used from the technical intention of further improving the aesthetic appearance.

[0012]

When the jewelry of the present invention is worn as a necklace, for example, the main part of the cascading body exhibits the above-mentioned three-dimensional form and continuous waveform form with respect to the wearing surface (bare surface or clothing surface). The number of decorative bodies present in the unit span of the state of the cascade is particularly increased compared to the conventional monotonic straight-curve form, so the deluxe feeling as a jewelry is improved, and the three-dimensional form and wavy form of the decorative body are the same. Reflected light with respect to the incoming light beam shows different diffuse reflections based on the position and direction of each decorative body, and produces shadows due to the adjacent decorative bodies, so that there is a high-grade and deep physical vision that does not exist in conventional products It becomes a form, and the aesthetics as an accessory improve.

In the case of a three-dimensional form with respect to the wearing surface, the number of decorative bodies that come into direct contact with the wearing surface is significantly reduced, and there is no continuous contact, so that there is no "sweat damping phenomenon" or "stickiness". In addition to being excellent in wearability, discoloration and damage of the conventional decorative body based on bare skin contact can be prevented.

Further, the cascade of the jewelry according to the present invention is characterized in that the external pulling force in the longitudinal direction of the core wire is applied to the helical coil portion.
Since it is absorbed by the "elastic elongation of the corrugated portion", it can be easily stretched to be easily worn on the neck, and breakage of the bead caused by sudden strong external force can be effectively prevented. And the conventional skin damage due to the strong external force can be prevented.

On the other hand, the end locking structure of the accessory according to the present invention having the above-described structure locks and locks both ends of the tragus to the piece-shaped locking member by the above-mentioned overlapping set lock form of the rigid and flexible material which functions as a spring washer. The locking performance of the ornamental body group is stable, and it can withstand the external force when attaching and detaching accessories, the own weight load during wearing, the sudden stretching external force during wearing, etc., without causing the core wire to relax. Body shape is stable for a long time.

Since the interconnecting ring portion can be easily formed at the portion where the flexible wire constituting the superposed set of the rigid and flexible material is pulled out from the piece-shaped stopper, the rigid core wire is used. The setting of the annular connecting means of the tragus is extremely simple and accurate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of an accessory will be described with reference to FIGS.
This will be described with reference to FIG. That is, the accessory 1 of this embodiment
Is a necklace N having a main part of a cascading pearl 2 formed by passing a group of pearl decorations 3 through a single core wire 4, and a helical coil portion at an intermediate portion corresponding to the main part of the cascading body 2 5 is provided.

More specifically, the core wire 4 is made of Ni of a shape memory alloy wire.
In the use temperature range (approximately 0 ° C. to 40 ° C.) where the necklace N is worn, the intermediate portion is “coil pitch P and coil diameter D (see FIG. 2).
A shape having a coil portion 5 that maintains the "form of a coil spring of about six turns", and the core wire 4 is formed in a continuous bead 2 which passes through each through hole of the decorative body 3; In the normal wearing state of (1), the structure is such that the coil spring form of the coil section 5 is maintained.

The necklace N made up of the above-described beads 2 has the "end locking structure of the beads 2" according to one embodiment of the "end locking structure of the accessory" of the present invention. .

That is, (see FIG. 3), following the last decorative body 3A at both ends of the continuous bead 2, a piece-shaped locking member 6 is inserted into the end of the core wire 4 to remove the decorative body 3 group from the core wire 4. In the end locking structure of the bead 2 which is stopped to stabilize the shape of the bead 2, in this embodiment, the rigid core wire 4 of Ni-Ti alloy wire and the connecting ring portion 8 for interconnection are used. The flexible wire 7 having a double polymerization is superimposed and set in the through hole 9 of the locking tool 6, and the core wire 4 and the flexible wire 7 in the set state are locked by the locking tool 6.
The flexible wire 7 and the core wire 4 protruding from the connection ring portion 8 to the outside of the locking tool 6 are pressed and fitted by the press-fit pin 10 press-fitted into the pin crimping hole 11 of the “rigid-flexible material locked form”.
The structure is fixed and locked.

The flexible wire 7 of this embodiment is "a rope material of 0.36 mm outer diameter obtained by applying a transparent nylon coat to a rope material of 0.27 mm diameter made of seven twisted cotton yarns". After the wire 7 and the core wire 4 are locked by crimping to the locking tool 6, unnecessary portions protruding from the locking tool 6 are cut and removed. In the figure, 13 is a link plate, and 14 is a connecting hook.

The necklace N of the jewelry 1 of the embodiment described above has the above-mentioned effect, and the aesthetic decoration of the necklace is further improved as compared with the conventional one, resulting in "gorgeousness" and "volume".
"Rich feeling" and the like can be further satisfied. In addition to improving the wearing feeling by preventing the decoration body 3 from being stained and preventing the user from feeling "sticky and sticky" at the time of wearing, the "pulling load generated in the cascading body 2" such as sudden pulling of the infant held by the coil part 5 can be improved. Is elastically stretched and absorbed, so that breakage damage of the bead body 2 and skin damage of the neck of the necklace N can be effectively prevented. And since the both ends locking structure which maintains the annular shape at the time of wearing is made of the above-mentioned rigid and flexible material superposed and fixed, even if the core wire 4 is a rigid wire having poor molding workability, the ends of the continuous beads 2 are interconnected. The countermeasure is made easy, and the annular connection performance is stabilized.

Further, the end locking structure of this embodiment has the following specific action since the twisted rope material is used as the flexible wire. That is, when the connecting ring portion 8 protruding from the locking tool 6 receives the light and reaches the rope surface through the transparent nylon coating, "when the light receiving portion is unevenly reflected by the uneven surface where the twisted top portion and the twisted valley portion are densely formed and the light reception is irregularly reflected. It is conceivable that, for example, the connection ring portion 8 receiving sunlight at the window or the like is visually recognized as exhibiting a similar phenomenon of "ripple wave pattern where sunlight shines", and the aesthetic effect of the necklace N can be further improved. Although the connecting ring portion 8 is present on the back of the neck in the worn state, the above-mentioned specific action can be effectively enjoyed by setting it slightly longer.

Next, another embodiment of the accessory 1 of the present invention will be described. That is, a core wire 4 using a shape memory alloy wire of a Ni—Ti alloy wire having a coil portion 5 similar to the embodiment of FIG.
The core wire 4 of this embodiment is provided with a "gray" or aluminum vapor-deposited film from which an oxide film on the surface of a Ni--Ti alloy wire has been removed. Has a surface color similar to the pearl surface color.

Since the core 4 of the Ni-Ti alloy wire whose surface is blackened by the oxide film has a gray color or aluminum color close to pearl color, the continuous beads 2 of this embodiment are blackened Ni-Ti. A pearl penetrating the alloy wire appears dark, and the core wire 4 appearing between the pearls becomes a one-point black spot, thereby preventing a bad phenomenon that impairs aesthetic appearance.
There is a specific action of improving the aesthetics of the continuous bead body 2 in which the core wire 4 is made of a Ti alloy wire.

That is, when the continuous bead 2 composed of general pearls shining pale yellow and white is formed into a three-dimensional form by the coil part 5 and the corrugated part W, the degree of exposure of the core wire 4 between the pearls in the three-dimensional form part becomes high, The low-brightness black exposure point of the converted core wire 4 causes an illusion as an expanded color or an advanced color and is visually recognized (complementary color action by a known visual illusion), which significantly impairs the visual aesthetic appearance (pearl color toning) of the pearl pearl 2. A defective phenomenon occurs. However, in the case of the above-described embodiment, the failure phenomenon is solved by the “appearance color of the pearl and the core wire 4 having a small difference in lightness”, and the original beautiful appearance of the pearl pearl can be stably secured. As described above, the embodiment described above includes the decorative body 3 and the core wire 4.
Is made to be an approximate color so that there is no difference in lightness. In the case of a black pearl, the black core wire 4 is preferable.

The removal of the oxide film from the Ni—Ti alloy wire is performed by setting the Ni—Ti alloy wire to be the core wire 4 to “water = 6.
5 · Nitric acid = 4 · Hydrofluoric acid = 1 ”, immersion treatment for 3 minutes at a liquid temperature of 25 ° C., ultrasonic cleaning, and then immersion treatment in warm water for 2 to 3 hours and pulling up The aluminum vapor deposition film is formed by a known sputtering method or the like.

Next, another embodiment of the accessory 1 of the present invention will be described with reference to FIGS. That is, the main part of the bead 2 in which the group of pearl decorations 3 is inserted into the core wire 4 of the Ni-Ti alloy wire of the shape memory alloy wire is formed in a three-dimensional form, and the bead 2 of FIG. 4 is shown in FIG. Core wire 4 with coil part 5 shown
This coil part 5 is composed of “coil diameter = about 12 mm ·
Coil pitch P = approximately 15 mm, number of coils = approximately 14 "
The main part of the continuous bead 2 that forms an annular shape when worn has a dense coil shape.

FIG. 6 shows a form in which jewels other than pearls or other decorations 3C made of metal are interspersed with or suspended from a continuous pearl 2 having pearls 5 having a coil portion 5. ing. In the embodiment of FIG. 6, the gravity increases due to the presence of the decorative body 3C, and the "gravity which tends to hang down the middle lower part of the continuous bead 2" when worn on the neck is changed to a rigid Ni-T.
Since the coil portion 5 of the i-alloy wire carries the coil while maintaining the coil shape, it is possible to prevent a failure phenomenon of "dazzling" due to gravity and to ensure a good appearance when the necklace N is worn.

On the other hand, the one shown in FIG. 7 has a main part of the continuous bead 2 formed as a continuous wavy portion W, and the one shown in FIG. This is a form in which a continuous waveform is drawn on the (bare skin or clothing surface) 12, and the one shown in FIG. The necklace N of the embodiment of FIG. 7 has the same / similar action as the three-dimensional form of the coil portion 5 of the embodiment.

Next, a description will be given of another embodiment of the end locking structure of the accessory according to the present invention. That is, although not shown, the locking device 6
In the case of "the rigid core wire 4 and the flexible wire 7 are overlapped and locked", the flexible wire 7 may have a "structure with resin coating containing a metal powder such as alumina". According to this embodiment, the metal powder in the resin coating of the flexible wire 7 crimped by the press-fit pin 10 or the like functions as “anchor between the rigid core wire 4 and the peripheral wall of the through hole of the locking tool 6”, The locking force of the locking tool 6 is further stabilized and improved.

The accessory 1 of the present invention is not limited to the above-described embodiment, and the shape memory alloy wire forming the core wire 4 has a "shape recovery characteristic by stress" which maintains a predetermined shape under the stress of wearing. In some cases, a “screw pin” that is screwed into a female screw hole may be used instead of the press-fit pin 10 that presses and locks the core wire 4 and the flexible wire 7 in the locking tool 6. . Further, the present invention is applied not only to the necklace N of the above-described embodiment but also to a bracelet and other accessories that form the main part of the continuous bead 2. The end connection structure may be a known means (exemplified in FIG. 6) other than the embodiment in FIG.
