Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member for ornaments, which is used for necklaces, bracelets, etc., by knitting fine metal wires, and a knitting needle used for knitting fine metal wires.

[0002]

2. Description of the Related Art Conventionally, almost all ornaments such as necklaces and bracelets are made by, for example, connecting Kihei-shaped members in a chain shape and attaching a connecting tool to both ends thereof. ..

[0003]

Due to the structure of such ornaments, the members formed as described above are brazed or spot welded one by one, and are pressed one by one to be continuously arranged. It will take a lot of work as it does. Therefore, due to price competition with other companies in the same industry, there is a problem in that even if automation is carried out to reduce the cost, the labor can not be saved so much and the cost cannot be reduced. A large number of such ornaments have been provided to the market so far, and they are neither novel, nor agitate the purchaser's willingness to purchase. Therefore, it is an ornament that is not very advantageous to the manufacturer, and recently there is a demand for ornaments such as necklaces and bracelets with a new structure.

By the way, the present inventor has been earnestly studying to obtain a decorative article using a fine wire of noble metal.
It has been known that a woven or knitted fine metal wire has a brilliance that is rich in aesthetics that has never existed before because the brightness of each fine metal wire overlaps. Therefore, the inventor of the present invention thought to provide a braided precious metal wire as an ornamental member in place of the above ornamental item.
Further, the present inventor has paid attention to the fact that there has been no ornamental article such as a necklace or a bracelet, which has a ring shape having elasticity and flexibility. Therefore, it has been found that the present invention provides a member for an accessory in which a fine metal wire is knitted.

As shown in FIG. 1, knitting of knitted fabric is knitting of a fine precious metal wire 1 into a loop shape 2.
The knitting can be done by hand knitting using a knitting machine or using a crochet or bamboo needle. When knitting with a knitting machine,
A knitting needle 3 having a U-shaped bent portion 4 for hooking the noble metal thin wire 1 at the tip and a return piece 5 for separating the noble metal thin wire 1 from the knitting needle 3 as shown in FIG. As for the knitting method, the precious metal thin wire 1 is knitted by the knitting needle 3 ascending or projecting, or descending or retracting at a knitting needle mounting base (not shown). Knitting needle 3
As shown in FIG. 3, while descending or immersing, while catching the new precious metal fine wire 1 with the hook and the return piece (in the state shown by the chain double-dashed line), It is disengaged from the knitting needle 3 by the return piece 5 (in the state shown by the solid line). Next, when rising or protruding, the return piece is immersed in the needle bar 6 with the precious metal thin wire 1 (the state shown in FIG. 1). Next, the return piece 5 is pulled out from the needle bar 6 by the precious metal thin wire 1 while descending or retracting again. Then, returning to, the new precious metal fine wire 1 ′ is captured, the precious metal fine wire 1 previously captured is released from the knitting needle 3, and this is repeated to knit the precious metal fine wire.

By the way, the precious metal fine wire can be knitted by a knitting machine having a generally well-known mechanism which is usually used as described above or provided as a toy. Precious metal wires sometimes cut during the process. As a result of conducting various experiments to investigate the cause, in the ordinary knitting needle for knitting wool yarn and the like, since the width of the hook portion is large, the return piece is stored in the needle bar. Because the amount of protrusion from the needle bar at the tip is large, unlike a woolen thread, the precious metal thin wire with extremely small elasticity stretches the precious metal thin wire braided between the knitting needles when passing through the hook portion or the return piece. As shown in FIG. 4, a portion P bent by the needle bar 6 of the knitting needle 3 of a precious metal fine wire.
It was found that a large amount of tension and frictional resistance are applied to the wire, which causes the precious metal fine wire to break.

As a result of further various experiments and examinations, in order to knit a fine metal wire such as a noble metal without cutting, the width of the needle bar of the knitting needle, the width of the hook portion, the protruding amount of the barb piece and the wire diameter of the metal thin wire. I found that there was some relation between them.
Therefore, when the width of the hook portion of the knitting needle cut by the precious metal fine wire and the protruding amount of the return piece were measured and investigated, the width of the hook portion was 2.0 to 2.5 times that of the needle bar. The amount was up to 3.0 times to 5.0 times the wire diameter of the precious metal fine wire. The inventor of the present invention needs to have a knitting needle for knitting a precious metal thin wire without cutting the width of the hook portion / the width of the needle bar, the protruding amount of the return piece / the diameter of the precious metal thin wire, or less. That is, the present invention has been realized, and the present invention has been achieved.

[0008]

In order to provide a knitting needle for knitting a member for jewelry and a precious metal fine wire as described above, the present invention comprises a member for jewelry that is knitted with knitted precious metal, and expands and contracts. The ornamental member has a bendable shape. The knitting needle for knitting precious metal fine wire is a knitting needle for knitting the fine metal wire, and the width of the hook bent into a U shape that hooks the fine metal wire at the tip is about 1.1 to 1.3 of the width of the needle bar. Double the structure. Furthermore, in the state where the barb strip for separating the metal fine wire from the knitting needle is housed in the needle bar, the protruding amount of the tip of the barb bar from the needle bar is about 0.8 to 1.5 times the wire diameter of the metal braid. The structure.

The noble metal fine wire in the present invention is preferably a single wire or a twisted wire of gold, silver, platinum and an alloy thereof, but may be a wire or a twisted wire of another flexible noble metal. Fine wire diameter is about 0.1 mm
If it becomes thinner, the rigidity of the knitted fabric is weak and it is easily deformed by an external force, which is not preferable. On the other hand, if the diameter exceeds about 1.0 mm, the rigidity of the thin wire increases and it becomes inefficient in work. Accordingly, the preferred wire diameter is approximately in the range of about 0.1 mm to about 1.0 mm in diameter.

A knitting machine can be used to knit the precious metal fine wire into the knitting, and the knitting machine is an ordinary knitting machine that has been conventionally used or provided in toys and the like. It does not have a special mechanism for knitting.

In order to knit the precious metal fine wire by using the knitting machine, it is preferable to knit using the knitting needle as described above, but even if the knitting needle having the above-mentioned dimensional relationship is used, as shown in FIG. If the curvature of the bent portion P of the noble metal fine wire 1 is too small, the noble metal fine wire 1 is likely to be cut. Stuff)
Is not good.

When knitting the precious metal fine wire, in order to reduce the frictional resistance between the knitting needle and the metal fine wire such as the precious metal, it may be knitted while applying or spraying lubricating oil or the like.

[0013]

Since the precious metal fine wire is knitted to form the ornament member, the brilliance of each precious metal thin wire is superposed on the surface of the ornament to give a complex and elegant shine.

When a fine metal wire such as a precious metal is knitted by using a knitting machine equipped with the knitting needle of the present invention, since the width of the hook portion of the knitting needle and the protruding amount of the return piece are small, the tension and friction resistance acting on the metal thin wire are small. Tesumi Metal thin wire can be knitted without cutting.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. Example 1 First, using a well-known mechanism, a knitting machine (not shown) that the present inventor himself made was used, and the width L of the hook 4 was 2.0 mm and the tip of the return piece 5 was A knitting needle 3 having a protrusion amount M from the needle bar 6 of 0.3 mm and a width N of the needle bar 6 of 1.6 mm was attached. Next, a precious metal fine wire 1 of 18K gold alloy (Au 75%, Ag 12.5%, Cu 12.5%) having a diameter of 0.2 mm is set, and the precious metal fine wire 1 has a loop shape 2 as shown in FIG. It was knitted into a knitted knitted fabric. As shown in Table 1, the relationship value between the precious metal fine wire 1 and the knitting needle 3 is the width L

[0021]

[Table 1]

The braided ornamental member 7 can be made into a necklace ornament by attaching connecting members 8 similar to those used in necklaces on both ends, as shown in FIG. 6, for example. it can.

[0023]

Since the decorative article member of the present invention is composed of precious metal fine wires, the precious metal fine wires are overlapped with the brilliance of each one, so that the decoration has a special brilliance which has never been seen before. Goods parts could be obtained. Further, since the present ornamental member is stretchable and flexible because it is formed by knitting, the movement of the present ornamental member by rocking causes
Its brilliance has the advantage of showing different brilliance.

In the knitting needle of the present invention, even if the precious metal thin wire is knitted, the width of the hook portion of the knitting needle and the protruding amount of the return piece are small, so that the tension and frictional resistance acting on the precious metal thin wire are small,
Never cut precious metal wires. Therefore, it is possible to continuously and rapidly produce, by machine knitting, a member for an ornamental article made of a precious metal fine wire. Therefore, not only a member for ornaments made of a fine metal wire having a composition such as iron, aluminum, brass, copper, and stainless steel, but also a member made by knitting a fine metal wire used for other purposes such as a shield member for a lead wire. Can also be provided.
