Or jewelry such as jade, opal, and emerald, and pearls, etc., with high-quality decorative bodies (hereinafter collectively referred to simply as “decorative balls”) with chain-through holes, platinum, stainless steel, etc. With respect to a processing method for flexibly connecting a large number or a plurality of chains to a necklace or the like using a metal chain, the object is to significantly reduce costs and improve work efficiency.

  Various chain processing methods have been proposed so far to connect necklaces that are hollow inside to form necklaces, etc., but for example, a large number of spheres such as a perfect circle or an ellipse are used. It has been common for a long time to form through holes in each of the internal hollow noble metal bodies, and to lead them through a linear body such as a thread or a wire and flexibly connect them.

  In addition to this, a plurality of ring-shaped members formed by forming through holes in each of the plurality of pearls and having both end portions welded with a welding material are connected to each of these ring-shaped members. A necklace having a connecting member for producing the same and a manufacturing method thereof (see Japanese Patent Application Laid-Open No. 7-289320), or a solvent inside a ring member of a plurality of ring members connected in a chain shape A chain for jewelry, in which a plurality of top members are integrated by injecting a melted filler such as an epoxy resin, and holding and drying and solidifying the ring members in a ring using surface tension, and a manufacturing method thereof (See JP-A-9-294615) is also known.

  In addition, the design part is designed to be locked in the middle of the decorative chain, and a through hole slightly larger than the diameter of the decorative chain to be penetrated is formed at the target position of each design part. In addition, a decorative chain design part configured to have a hollow elastic body in the shell of the design part and a manufacturing method thereof (see JP 2000-245516 A) are also known.

  Furthermore, in the noble metal chain developed by the present inventors, in which a large number of internal hollow bodies are connected in a chain-like manner to each other in a flexible manner, each sphere of the noble metal chain has its symmetry. A part of the surface is cut so as to reach the inside of the hollow and opened in the hollow, and the cut thick wall surface is exposed to the outside. Decorative noble metal chain that allows other decorative objects such as precious metals or jewelry to be easily attached in the two-dimensional or three-dimensional directions by passing the yarns and wires of the metal and a method for manufacturing the same (Japanese Patent Laid-Open No. 11-212) Also known).

In the case of the processing method of the chain with decorative balls that is held flexibly, there are the following effects.

  In other words, depending on the size of the decorative ball, it is not necessary to prepare chains with different thicknesses. Even when the inner diameter of the through-hole of the ball is small, the chain can be used as a chain having excellent durability since the tensile strength of the chain hardly changes.

The state of implementation of the chain (A) used in the processing method of the chain with a decorative ball of the present invention and the second passing means for slimming the chain and passing the slimmed chain into the through hole of the decorative ball will be described. (B) for explaining the principle. After passing the chain through the through hole of each decorative ball, or after passing the slimmed chain, the connector part exposed to the outside from the interior of the decorative ball of the chain has a diameter larger than the inner clearance of the connector. In addition, a chain with a decorative ball in which a diameter-enlarging bar whose tip is sharpened to a degree smaller than the inner gap of the connector is inserted to expand the outer diameter of the connector part from the through hole of the decorative ball. The principal part expansion explanatory drawing which showed an example of the processing condition. The elements on larger scale showing another Example of the connector which comprises a chain | strand. It is another Example of this invention, Comprising: The partial expanded view which represented only the tubular decorative ball in the cross section.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 2 shows a general processing method according to the present invention, where 1 is a decorative ball and 2 is a chain. As for the decorative ball 1 used in this case, as described above, a hollow shell body such as a round ball, an oval ball, a tubular body or the like formed of platinum, gold, silver or the like, or a chain-drawing hole therein. Ornamental parts made of non-hollow bodies provided with jewels such as jade, opal and emerald, and high-grade ornaments such as pearls provided with chain-through holes inside.

  Each of the decorative balls 1 is formed with a through-hole 1a that opens to a symmetrical plane and allows the chain 2 to pass therethrough. As for the chain 2, as shown in FIG. 1A, for example, an ellipse-shaped connector 2a made of platinum, stainless steel, or other metal is connected to the adjacent connector 2a and the inner circumference of the short end of each endless ellipse. A plurality of chains 2 are connected in a cross shape and connected in series to form a flexible fixed-length chain 2.

  In this case, the thickness of the chain 2 shown in FIG. 1A (the outer diameter on the short side of each connector 2a) is substantially equal to or narrower than the opening diameter of the through hole 1a formed in the decorative ball 1 In FIG. 1, the chain 2 (FIG. 1A) can be used as it is. Specifically, for example, when a decorative ball 1 made of a plurality of or a plurality of internal hollow shells such as platinum is attached to a flexible connecting chain (necklace) 2 of a certain length that hangs around the neck, the symmetry plane of each decorative ball In addition, the through holes 1a and 1a are formed in advance, and these decorative balls are sequentially drawn through the chains shown in FIG. 1 (A) through the through holes.

  Further, the inner circumferential side gap 2b of the connector 2a exposed to the outside of both sides from the interior of the decorative ball 1 of the chain 2 is larger in diameter than the inner gap of the connector 2a, and the tip is at least The expanding bar B, which is sharpened to a diameter smaller than the inner gap of the connector 2a, is inserted into the ellipse of the connecting bar 2a by the outer diameter of the expanding bar B by manually pressing the sharpened tip first. The gap 2b portion on the inner peripheral side that has been subjected to expansion is expanded, and thereby the outer diameter of the gap 2b portion exposed to the outside of the decorative ball 1 of the connector 2a is expanded from the inner diameter of the through hole 1a of the decorative ball 1 The movement of the ball 1 along the chain 2 can be restricted.

  Each connector 2a shown in FIG. 2 represents a shape after the expansion bar B is pulled out from the inner circumferential side gap 2b of the connector 2a and the portion is expanded. Therefore, regarding the outer diameter of the expanding bar B used in this case, the outer diameter (thickness) of the expanding bar B is equal to both of the oblong contour portions of the connector 2a sandwiching the expanding bar B. It is necessary to use a material that is so thick that the dimension to which the thickness is added is larger than the inner diameter of the through-hole 1a of the decorative ball 1. In addition, about the expansion | deployment operation | work of the clearance gap 2b part of the inner peripheral side which carried out the ellipse shape of the connector 2a by the above-mentioned press-fitting of the expansion | deployment bar | burr B, the both side parts are expanded manually for every decoration ball 1. It is realistic for the time being to open it.

  However, in this case, for example, as shown in FIG. 3B described later, for example, each connector 2a constituting the chain 2 is twisted so as to have an angle of 90 degrees with respect to the center line in the longitudinal direction. In this case, a jig for orderly placing the chain 2 in a state where the decorative ball 1 has been passed through is created, and the gap 2b portions of the connectors 2a on both sides of the decorative ball 1 are aligned on the jig. The open bars B that can be press-fitted together into the gaps 2b are set to face each other and set to the chain 2 at a predetermined length. It is also possible to efficiently expand the inner circumferential side gap 2b of each connector 2a in an elliptical shape.

  Further, if the size (thickness) of the connector 2a constituting the chain 2 is made too thin, generally strength deterioration cannot be avoided. In particular, when a small decorative ball 1 is used, it is desirable to use a chain 2 having a standard thickness. In this case, the standard chain 2 shown in FIG. 1A is shown in FIG. It is necessary to use it after thinning it once. That is, in the case where a large number or a plurality of decorative balls 1 are passed through a chain 2 in which a substantially oval-shaped connector 2a having a certain length is connected and flexibly attached, a substantially oval shape having a certain length is attached. It is necessary to apply first processing means for slimming the chain connected to the connector 2a so that the thickness of the chain becomes thinner than the diameter A of the through hole of the decorative ball.

  As the slimming means used here, for example, by pulling out a known die set to the diameter of the target chain 2 with the diameter of the extraction hole, the short side width of each connector 2a should be reduced and attached. A chain 2 thinner than the opening diameter of the through-hole 1a of the decorative ball 1 can be easily obtained. In addition to the die, each connector 2a constituting the chain 2 is individually struck with a hammer, or each connector using tools such as a pliers tool, a hydraulic punch, a manual punch, etc. Slimming can also be achieved by compressing 2a from the width direction.

  Next, in the through hole 1a of each decorative ball 1, second passing means for passing the chain 2 slimmed by the first processing means described above is applied. In this case, the slimmed chain 2 is thinner than the opening diameter AA of the through hole 1a of the decorative ball 1 as shown in FIG. It can be easily pulled in the direction of arrow B.

  Further, after passing the slimmed chain 2 into the through-hole 1a of each decorative ball 1, the portion of the chain 2 exposed from the inside of the decorative ball 1 to both sides of the outer side of the chain 2 is larger than the inner gap of the connector. In addition, the expanding bar B whose tip is sharpened at least so as to have a diameter smaller than the inner gap of the connector 2a is press-fitted into the leading end of the sharpened tip B so that the outer diameter of the connector 2a portion is reduced. A third enlargement means adapted to enlarge from the through hole 1a is applied.

  In other words, the oval inner gap 2b of the connector 2a has a diameter larger than the inner gap of the connector 2a, and the tip is sharpened to a degree smaller than the inner gap of the connector 2a. The gap 2b on the inner circumferential side of the connector 2a is formed into an oval shape by the outer diameter of the spreading bar B by manually or mechanically press-fitting the expanded bar B with a sharp tip. The outer diameter of the gap 2b exposed to the outside of the decorative ball 1 of the connector 2a is thereby expanded from the inner diameter of the through hole 1a of the decorative ball 1 and moved along the chain 2 of the decorative ball 1. Can be regulated.

  It should be noted that the chain 2 used in the present invention is not necessarily limited to the structure described in FIG. 1 (A) described above, and for example, as shown in FIG. Each of the connectors 22a, as shown in FIG. 8B, or the chain 22 having a configuration in which the connector 22a is twisted by 180 degrees in a shape of approximately 8 around the major axis in the longitudinal direction, The use of the chain 22 or the like having a configuration in which a twist of 90 degrees is applied about the longitudinal major axis is also included.

  The chain used in the present invention is not limited to the above-described components, and a non-circular body, various decorative bodies, or an oval-shaped connector is intermittently twisted between the connected connectors. The thing of the structure made to connect what was deformed is also contained.

  Further, FIG. 4 shows another embodiment of the present invention. In this case, as the decorative ball 1 to be used, a tubular (pipe) shape is used. As shown in FIG. 4A, after passing the same chain 2 as in the above-described embodiment into the hollow of each decorative ball 1, the connector 2 a exposed from the inside of the decorative ball 1 of the chain 2 to both sides outside An expanding bar B having an oval inner circumferential gap 2b having a diameter larger than the inner gap of the connector 2a and having a tip sharpened to a degree smaller than the inner gap of the connector 2a. (Similar to the expanding bar B used in FIG. 2 described above) is manually press-fitted with a sharpened tip first.

  As a result, the oval inner gap 2b of the connector 2a is expanded by the outer diameter of the expanding bar B, whereby the tubular shape of the connector 2a as shown in FIG. The movement of the decorative ball 1 along the chain 2 can be restricted by enlarging the outer diameter of the gap 2b portion exposed outward from both sides of each decorative ball 1 from the inner diameter of the through hole 1a of the decorative ball 1. .
