Wire for ornaments and method for making the same
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to wires for ornaments such as necklaces, bracelets or the like and, more particularly, to a wire for ornaments which dispenses with connecting elements for jewels, which is light in weight, and which is also easy in handling. 
     2. Related Art and Prior Art Statement 
     In necklaces or bracelets in which jewels such as pearls, crystals, corals, onyxes, turquoises or the like are linked together, connecting threads such as silk, artificial or chemical fibers or the like have been used. However, there are cases where the connecting threads having such material generate looseness with the passage of time, and are snapped. For this reason, it has been preferred to use metallic wires made of stainless steel as the connecting threads. FIG. 9 of the attached drawings shows the conventional or prior-art ornament such as a necklace, a bracelet or the like which has been manufactured by the use of a metallic wire. A metallic wire 90 made of stainless steel or the like passes through a plurality of jewels 91 to thereby connect the jewels 91 to each other. The wire 90 has a forward end thereof to which a fastener (clasp) 93 is connected through a connecting element 92. The fastener 93 is detachably engaged with a hook element (not shown) which is mounted on the other end of the wire 90, in order to make the ornaments endless. The connecting element 92 serves as a decoration or an ornament as well. However, an original or essential object thereof is to connect the wire 90 and the fastener 93 to each other. This is because the wire 90 serving as the connecting thread and the fastener 93 cannot directly be connected to each other and, accordingly, are connected to each other through the connecting element 92. 
     FIG. 10 shows a structure or construction in which the connecting element 92 is used to connect the wire 90 and the fastener 93 to each other. The connecting element 92 has various components including an end piece 95, a first connecting piece 96, a second connecting piece 97 and a spacer piece 98. First, the end piece 95 is fixedly mounted on the forward end of the wire 90 by soldering. Meanwhile, a U-shaped pin 99 is connected to the fastener 93. The U-shaped pin 99 is inserted into the first connecting piece 96. Inserted forward ends of the U-shaped pin 99 are caulked. Thus, the fastener 93 and the first connecting piece 96 are connected to each other. Subsequently, the wire 90 is caused to pass through the second connecting piece 97, and the jewels 91 are mounted on the wire 90. Subsequently, the second connecting piece 97 is inserted into the spacer piece 98. Under such state or condition, the second connecting piece 97 and the first connecting piece 96 are engaged with each other, and are joined to each other. Thus, the wire 90 and the fastener 93 are connected to each other through the connecting element 92. However, since the spacer piece 98 of the connecting element 92 is processed in decoration, the connecting element 92 per se is recognized as being a decoration or an ornament. 
     In this manner, the prior-art ornaments such as necklaces, bracelets or the like have the following problem. That is, since the prior-art ornaments such as necklaces, bracelets or the like use the connecting element 92 upon connection of the fastener 93 and the wire 90 to each other, the connecting element 92 is bulky and becomes an obstacle or a nuisance. Further, the weight of the connecting element 92 increases the weight of the entire ornament. Particularly, in a case where the wire 90 is made to a multiple connecting structure such as two-connection, three-connection or the like structure, the connecting elements are large-sized in keeping therewith and increase in number. Thus, the above-described disadvantage is conspicuous. Moreover, the prior-art ornaments have the following problem. That is, in the prior-art ornaments, the connecting element 92 is conspicuous, and the original functions of the necklaces or the bracelets which impart ornamentation by the jewels 91 is reduced. Furthermore, the jewels are damaged or flawed due to the fact that the connecting element 92 is in contact with the jewels 91. 
     OBJECTS OF THE INVENTION 
     An object of the invention is to provide a wire for ornaments which solves the above-discussed disadvantages and problems, and which is made of a structure capable of being directly connected to a fastener, whereby the wire is not damaged in ornamentation and without the necessity of a separate connecting element. 
     An another object of the invention is to provide a wire for ornaments which, since a connecting element is dispensed with, reduces the weight of the ornaments per se even if the wire is made with a multiple connecting structure, and which considerably improves handling thereof. 
     Further, another object of the invention is to provide a wire for ornaments in which contact between a connecting element and jewels does not mar the jewels, and damage is not imparted to the jewels. 
     Moreover, another object of the invention is to provide a wire for ornaments which simplifies and facilitates assembling of the ornaments without the necessity of complicated steps, since a connecting element is dispensed with. 
     SUMMARY OF THE INVENTION 
     The invention is arranged such that connecting rings which have metallic elongations as a whole, which are large in diameter, which have a flat shape or contour and which are formed respectively with through bores in a thickness direction are integrally formed at both ends of a wire, whereby the rings at the ends in the above-described arrangement can directly be connected to a fastener or the like through the through bore. Since the rings are flat in shape, ornamentation is not damaged. For this reason, it is not necessary to use a connecting element to cover or hide the ring. A connecting element such as a prior art one is not required. The wire for ornaments is light in weight and is easy to handle. The jewels are not damaged. Further, since the rings are larger in diameter than the elongation, the wire for ornaments has the function to prevent the jewels from falling off also in the case where the jewels are linked to each other. 
     Moreover, since packings are interposed respectively between the adjacent jewels which pass over the body of the wire and between the rings and the jewels at both ends in a linking direction, contact between the jewels with each other and contact between the jewels and the rings with each other are prevented to effectively prevent the jewels from being marred. Thus, abrasion or wear of the jewels is restrained. 
     Furthermore, the rings are so arranged as to process, in high temperature, ends of a body of the wire to make the ends to a ball shape. The balls are so urged as to be made to a flat shape. Subsequently, the through bores are punched or blanked in a thickness direction. 
     As metal which is used for the wire according to the invention, noble or precious metals such as gold, silver, platinum and the like including stainless steel, brass and the like can be selected. In case of the wire made of the noble metals or the brass, the wire per se has ornamentation and, accordingly, the wire can directly be applied to the necklaces or the bracelets. It is dispensed with to link jewels to each other.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIGS. 1 and 2 show an embodiment of a necklace or a bracelet in which jewels are linked to each other, to which the invention is applied. In FIGS. 1 and 2, a wire 1 made of metal such as stainless steel or the like, is provided with an elongated body 2 and a pair of rings 3 integrally formed respectively at both ends of the body 2. The elongated body 2 is arranged such that jewels 4 such as pearls, crystals or the like are linked to each other. For this reason, the elongated body 2 passes through the plurality of jewels 4. In this case, packings 5 are interposed respectively between the adjacent jewels 4 and between the jewels 4 at both ends in a linking direction and the rings 3. Thus, the jewels 4, and the jewels 4 and the rings 3 are prevented from being in contact with each other, and abrasion of the jewels 4 is restrained. 
     The rings 3 are integrally formed respectively at both ends of the body 2. As shown in FIG. 3, each of the rings 3 is flat and larger in diameter than a diameter of the body 2. Thus, the jewels 4 which are linked to the body 2 are prevented from slipping off. Each of the rings 3 is formed therein with a through bore 6 in a direction of a thickness of the ring 3. The through bore 6 is used as a connecting element in case where the wire 1 is made to an endless annulus or ring. For example, in FIG. 1, a connecting ring 8 of a fastener 7 is inserted into the through bore 6 in the left-hand ring 3, whereby the connecting ring 8 is directly connected to the fastener 7. Against this, a hook element (not shown) is connected to the through bore 6 in the right-hand ring 3. The hook element and the fastener 7 are connected to each other, whereby the wire 1 is formed into an endless ring. Thus, the wire 1 is used as a necklace or a bracelet. 
     The embodiment is arranged such that the rings 3 are integrally formed respectively at both ends of the elongated body 2, and the ring 3 can directly be connected to the fastener 7 or the hook element. For this reason, the prior-art connecting element is dispensed with. Not only is the embodiment not bulky and does not serve as an obstacle or a nuisance, but also the weight thereof does not increase, and the embodiment is convenient to use. Further, the jewels are not wounded or injured by contact with the connecting element like the prior art. Moreover, since the ring 3 is flat and is inconspicuous, ornamentation of the jewels is not damaged, and it is possible to give a feeling of high class or exclusion. Furthermore, since a complicated step of connecting the connecting element is dispensed with, assembling of the ornaments can simply be performed. 
     FIGS. 4 to 7 show an embodiment of a step of forming the ring 3. The body 2 of the wire 1 has an end thereof which is instantaneously processed in high temperature so as to be melted to thereby form a ball 20 (refer to FIG. 4). The ball 20 is urged so as to be made to a flat shape or contour larger in diameter than the body 2 (refer to FIG. 5). Subsequently, the through bore 6 is punched in a thickness direction thereof (refer to FIG. 6). Thus, as shown in FIGS. 6 and 7, it is possible to form the ring 3 integrally with the body 2, which is larger in diameter than the body 2, which has a flat shape or contour, and which has the through bore 6 in the thickness direction. In this case, a step illustrated in FIGS. 5 and 6 is such that setting is made within a mold, and the flattening and punching steps can simultaneously be performed. Thus, it is possible to shorten the steps, and processing is also improved efficiently. Since the ring 3 is made of metal the same in material as the body 2, the ring 3 has a strength of the order the same as that of the body 2, and forms a firm or stable connecting condition or state with respect to the body 2. Thus, the ring 3 is prevented from coming off from the body 2. 
     FIG. 8 shows a step of manufacturing the necklace or the bracelet after the ring 3 has been formed. The ring 3 is formed on the side adjacent to one end of the body 2. A side 24 adjacent to the other end of the body 2 is made to an acute form. The side 24 adjacent to the other end is inserted subsequently into the packings 5 and the jewels 4. After caulking so that the jewels 4 are not loosened, the processing illustrated in FIGS. 4 to 6 is applied to the side 24 adjacent to the other end. Thus, as shown in FIG. 2, a state results in which the jewels 4 are linked to each other. The arrangement can be used as the necklace or the bracelet. 
     Although an embodiment has been described relative to ornaments in which the jewels are linked or joined to each other, the invention can be applied to ornaments in which the wire per se is made of noble metal such as gold, silver, platinum or the like, whereby the wire per se serves also as the necklace or the bracelet. 
     The wire for the ornaments according to the invention is arranged such that the wire is large in diameter and has a flat shape or contour, the rings each having the through bore in the thickness direction are formed at both ends, and the rings are so used as to directly be connected to the fastener or the like. Accordingly, the connecting element can be dispensed with. For this reason, the rings are not bulky and do not increase in weight. Handling is facilitated, ornamentation is improved, and the jewels are prevented from being wound or injured. Thus, the invention has such an advantage as to provide the wire of this kind which does not exist in the prior art and which is superior.
