Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an end locking structure of jewelry such as a necklace or bracelet to wear hooked to the neck and arms.
[0002]
[Prior art]
Necklaces of typical accessories widely used in general are mainly composed of a chain of pearls and other ornaments such as pearls passed through a single core wire, and the ends of the chain are connected. It is in the basic form of engaging and ringing around the neck. As the core wire, one using a flexible thread such as silk thread or a shape memory alloy wire disclosed in Japanese Patent Application Laid-Open No. 2000-106923 is widely used. “It is configured in a flat-mounting configuration that hangs down due to gravity in contact with the wearer's skin and clothing surface.
[0003]
And, the both ends of the chain are connected to each other in a detachable manner by connecting the core wires drawn through the decorative bodies at both ends of the chain as shown in Utility Model Registration No. 3014576. An annular connection means is employed.
[0004]
[Problems to be solved by the invention]
Since the above conventional necklaces are in the above-mentioned flat-mounted form, when worn on the bare skin like in the summer or at the time of athletes, the bracelet is familiar with the bare skin and each of the decorative body groups hangs in direct contact with the bare skin As a result, sweat or bare skin adheres to it or blocks sweat, resulting in a “sticky feeling” and a decorative body such as a pearl that is darkened and impairs the beauty. And since the wearing necklace lacks a three-dimensional appearance with a flat visual feeling, a tendency to become a monotonous aesthetic is unavoidable and lacks in aesthetic appeal.
[0005]
And since the above-mentioned continuous bead has a structure that cannot be expanded and contracted in the length direction, there are cases in which it cannot be easily stretched by being slightly stretched when worn on the neck and is difficult to wear. And, for example, when the infant holding the body receives a strong extension external force such as pulling, the core wire may be stretched and become defective in shape, or may break and break apart. Necklace may bite into your neck and damage your skin.
[0006]
Further, in the above-described annular connecting means of the conventional necklace, when the core wire is made of a highly rigid wire material such as a shape memory alloy wire of a Ni (nickel) -Ti (titanium) alloy wire, the connecting ring portion There is a processing difficulty that makes it difficult to braze and weld to the piece-shaped locking device that prevents the formation process and the decorative body group from coming off, and it is difficult to take measures for the annular connection of the chain beads.
[0007]
The present invention provides an end locking structure for an accessory that eliminates the above-mentioned problems of the prior art.
[0008]
[Means for Solving the Problems]
The end locking structure of the accessory of the present invention that achieves the above-described object is as follows: “The ornamental group at the end of the accessory composed of a chain of jewels that are inserted into a single rigid core wire. A flexible wire rod having an end portion of the rigid core wire and a connecting ring portion at both ends of the continuous bracelet is set in a through-hole of a piece-like locking tool in a locking structure. The rigid core wire and the flexible wire material are configured as an end locking structure for an accessory characterized by a rigid and flexible material superposed set lock structure in which the press-fit pin or the screw pin is pressed and fixed.
[0009]
That is, the end portion locking structure of the jewelry according to the present invention having the above-described configuration is formed as a superposition lock form of the rigid and flexible material, so that the flexible wire is like a “spring washer of the nut tightening lock portion of the machine element”. It is characterized by the idea of further improving and stabilizing the lock locking force by functioning as a cushioning material between the locked rigid objects and the tightening lock, and the flexible wire material is cotton yarn, silk yarn, metal Rope material or single wire material twisted with yarn and non-metallic yarn is used, and from the technical intention to further improve the locking and fixing force, it is possible to form a form with a resin coating containing metal powder on the outer periphery of the rope material, or for further visual aesthetics From the technical intention of improving, there is a case where the rope body has a twisted configuration.
[0010]
[Action]
Since the end locking structure of the accessory of the present invention having the above-described configuration is configured to lock both ends of the chain bead to the block-shaped locking device by the above-described superposed set lock form of the rigid and flexible material that functions as a spring washer, The long-term shape of the bracelet is stable without causing loosening of the core wire with stable locking performance of the body group, withstands external forces when attaching and detaching jewelry, self-weight when wearing, and sudden extension external forces during wearing etc. To stabilize.
[0011]
And, since the ring part for interconnection can be easily formed in the lead-out part from the piece-like locking member of the flexible wire constituting the polymerization set form of the rigid flexible material, The formation setting of the annular connecting means can be made extremely simple and accurate.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
First, an embodiment of an accessory equipped with a terminal connection structure of the present invention will be described with reference to FIGS. That is, the accessory 1 of this embodiment corresponds to the main part of the rosary body 2 as a necklace N having a main part of a rosary body 2 formed by passing a group of pearl ornaments 3 through a single core wire 4 into a continuous pearl shape. It has a specific form in which a helical coil portion 5 is provided in the middle portion.
[0013]
Specifically, the core wire 4 is a Ni—Ti alloy wire (diameter = 0.4 mm) of a shape memory alloy wire (see FIG. 2), and the intermediate portion in the wearing temperature range (approximately 0 ° C. to 40 ° C.) of the necklace N Has a shape with a coil portion 5 that maintains a “coil spring configuration with a coil pitch P and a coil diameter D of about 6 windings”, and this core wire 4 is passed through each through hole of the decorative body 3. In the normal wearing state of this necklace N, it has the structure which maintains the coil spring form of the coil part 5.
[0014]
And the necklace N which consists of the above rosary body 2 has "the edge part latching structure of the rosary body 2" which consists of one Example of the "edge part latching structure of jewelry" of this invention.
[0015]
That is, (see FIG. 3) The piece-shaped locking member 6 is inserted into the end of the core wire 4 subsequent to the last decorative body 3A at both ends of the bracelet 2 to prevent the decorative body 3 group from being detached from the core wire 4. In the end portion locking structure of the continuous bead body 2 for stabilizing the shape of the continuous bead body 2, this embodiment has a Ni-Ti alloy wire rigid core wire 4 and an interconnecting connection ring portion 8. The overlapped flexible wire 7 is overlapped 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 press-fitted into the pin crimping hole 11 of the locking tool 6. By the press-fit pin 10, the flexible wire 7 and the core wire 4 which protrude the connecting ring portion 8 to the outside of the locking tool 6 are pressed and fixed, and the structure is fixed and locked in the “rigid and flexible material superposition lock form”.
[0016]
In addition, the flexible wire 7 of this example is “a rope material having an outer diameter of 0.36 mm obtained by applying a transparent nylon coat to a rope material having a diameter of 0.27 mm twisted of seven cotton yarns”. The core wire 4 is cut and removed from the unnecessary portion protruding from the locking tool 6 after the crimping lock to the locking tool 6. In the figure, 13 is a link plate, and 14 is a connecting hook.
[0017]
Since the necklace N of the accessory 1 of the above embodiment is composed of the above-mentioned rigid and flexible material superposition fixing structure that maintains the annular shape when worn, even when the core wire 4 is a rigid wire that is inferior in molding processability, The measures for mutual connection of the end portions of the bracelet 2 are facilitated, and the annular connection performance is stabilized.
[0018]
Furthermore, since the end locking structure of this embodiment uses a twisted rope material as a flexible wire, it has the following specific effects. That is, when the connecting ring portion 8 protruding from the locking tool 6 receives light and reaches the rope surface through the transparent nylon coating, “when the light reception is diffusely reflected at the same time as the light-dark difference is caused by the uneven surface where the twist top and the twist valley are densely present. For example, the connecting ring portion 8 that receives sunlight at the window or the like is visually recognized as exhibiting a similar phenomenon of “a ripple pattern in which a wave is shining by sunlight”, and the aesthetic effect of the necklace N can be further improved. In addition, although the connection ring part 8 exists in a neck back part in a wearing condition, the said specific effect | action can be enjoyed effectively by setting a little longer.
[0019]
Subsequently, another embodiment of the end portion locking structure of the accessory of the present invention will be described. That is, although not shown in the figure, in the “locking lock by superposing the rigid core wire 4 and the flexible wire 7” on the locking tool 6, the flexible wire 7 is “structured with a 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 pressed by the press-fit pin 10 or the like functions as “anchor between the rigid core wire 4 and the through hole peripheral wall of the locking tool 6”. The locking force of locking by the locking tool 6 is further stabilized and improved.
[0020]
In addition, the edge part latching structure of the jewelry of this invention is not limited to the said Example, It replaces with the press-fit pin 10 which carries out crimping | locking of the core wire 4 and the flexible wire 7 in the latching tool 6, and is a pin of a female screw hole. A “screw pin” that is screwed into the hole may be used. And it is applied not only to the necklace N of the said Example but to the bracelet and other accessories which make the main chain 2 main part.
[0021]
【The invention's effect】
As described above, the end portion locking structure of the accessory of the present invention is easy to interconnect the end portions of the bracelet body, and stabilizes the shape of the bracelet body so that the effect of the main body accessory device is smooth. There is effect such as supporting.
