[Prior art and problems to be solved]

 When forming ornaments with a large number of pearls arranged in a ring, generally, a technique of fixing pearls by gluing or caulking on a pedestal made of precious metal is often used. However, in such a case, there is a problem that the pearls are likely to fall off, and the caulking process requires a high degree of skill.

On the other hand, if an attempt is made to apply a structure in which pearls are connected with a thread like a necklace to a ring, a great tension force acts on the ring and the thread may be cut during long-term use. There is not preferable.

As a countermeasure against this, it is conceivable to use a metal wire rod having high strength in place of the string. In this case, the heat generated when the both ends of the wire rod inserted into the pearl are joined by welding such as brazing Then the pearls are altered and the commercial value is lost.

The present invention has been made in view of the above problems, and provides a pearl connecting structure that can connect pearls using a metal wire without degrading them and has a beautiful appearance. Is intended.

[0006]

[Means for Solving the Problems]

 To achieve the above object, in the present invention, an end portion of a metal wire rod that penetrates a plurality of pearls is folded back to form a locking ring portion by welding such as brazing, while an opening portion into which the locking ring portion is inserted is formed. A connecting body having both ends is provided, and the locking ring portions at both ends of the metal wire rod holding the pearl are inserted into the opening portions at both ends of the connecting body. The pins are inserted and fixed so as to penetrate, and the pearls on the metal wire and the connecting body are connected in an annular shape.

The pearls arranged in a ring form the pearls in two or more rows, and the end portions of the metal wire that penetrates the pearls in the rows are welded to each other to form locking ring portions at both ends of the pearl row. It can be formed. In this case, an intermediate body that interconnects a plurality of rows of metal wire rods may be interposed between pearls that are circumferentially adjacent to each other.

In addition, the connecting body may have a concave shape at the opposite ends to the pearls at both ends.

[0009]

[Action]

 The locking ring portions at both ends of the metal wire rod holding the pearls are fixed to the connecting body through pins. In this state, the locking ring portion is inserted into the opening of the connecting body, and thus is hidden from the outside. Therefore, a graceful connection structure suitable for a ring or the like is formed in which a plurality of pearls and the connection body are connected in an annular shape in appearance.

The locking ring part is formed by welding such as brazing to the end of the metal wire rod that penetrates the pearl, but since this locking ring part is inserted and fixed in the opening of the connecting body, only that much. It can be formed at a position remote from the pearl, thus avoiding the influence of heat on the pearl during welding and the risk of deterioration.

When the pearls are formed in two or more rows, a plurality of metal wire rods penetrating each row exerts higher strength and the end portions of the metal wire rods in each row are welded to each other. By doing so, the annular end can be easily formed, so that the workability is also good.

When the intermediate body that connects the metal wires of a plurality of rows to each other is provided, it is possible to prevent the pearls of each row from being deformed in the direction in which they are separated from each other in the axial direction, and By using the body as a fixed pedestal for jewelry or the like, the decorative effect or the degree of freedom in design can be increased.

When the both ends of the connecting body are provided with a concave shape, the pearls are well settled at the contact portion with the connecting body, and at the same time, a strong tension acts to cause the connecting body and the pearls adjacent thereto Prevents damage to pearls when rubbed together.

【Example】

 Hereinafter, an embodiment in which the present invention is applied as a ring will be described with reference to the accompanying drawings.

In each of the drawings starting from FIG. 1, 1 is a pearl, 2 is a connecting body, 3 is a metal wire rod that holds a plurality of pearls 1 and holds, 4 is a locking ring portion formed at the end thereof, 5 Indicates a rivet pin for locking the locking ring portion 4 with the connecting body 2. The connecting body 2, the metal wire rod 3, and the rivet pin 5 are made of a noble metal material such as 18 gold.

FIG. 2 shows details of a connecting portion between the connecting body 2 and the locking ring portion 4. The connecting body 2 has a substantially rectangular shape in a plan view and an arc shape as a side shape that forms a part of a ring shape forming a ring, and has locking ring portions 4 at the ends of the metal wire 3 at both ends thereof. An opening 2A to be inserted is formed with a predetermined depth, and a pin hole 2B is formed in the semi-diametrical direction so as to pass through the opening 2A. The connecting body 2 having such a shape is formed by, for example, the lost wax manufacturing method.

On the other hand, in this case, the locking ring portion 4 is formed into an eye shape by bending the end portion of the metal wire rod 3 in a circular shape and brazing the tip portion partially overlapped with the base portion of the ring as shown in the figure. Has been formed.

Each pearl 1 is formed with a through hole 1A through which the metal wire 3 is inserted, and a predetermined number of holes corresponding to the size of the ring are passed through the through hole 1A. It is held in series by the metal wire rod 3. The size of the ring can be adjusted depending on the size of the pearl 1 used.

The locking ring portions 4 at both ends are formed by brazing one side and passing the required number of pearls 1 and then brazing the other side. Since the locking ring portion 4 is separated from the pearl 1 at the end of the insertion portion which is inserted into the opening 2A of the connecting body 2, and the pearl 1 is packed on the other side, the distance is further increased. As a result, the heat at the time of brazing after passing through the pearl 1 does not directly reach the pearl 1, and therefore it is possible to surely avoid the problem that the pearl 1 is deteriorated by the influence of heat.

The locking ring portions 4 thus formed at both ends of the metal wire 3 are inserted into the openings 2A at both ends of the connecting body 2 so that the locking ring portions 4 and the pin holes 2B are penetrated. By inserting the rivet pin 5 into and crushing and fixing both ends of the rivet pin 5, an annular structure as a ring in which a plurality of pearls 1 are annularly connected is formed (see FIG. 1).

In this case, in this embodiment, as shown in the drawing, since substantially hemispherical concave portions 2C are formed at both ends of the connecting body 2, the connecting body 2 and the end portions thereof in the connected state are positioned. It fits well with the pearl 1, and there is less risk of damaging the pearl 1 when a strong force is applied while it is worn on the finger.

FIG. 3 shows another embodiment of the present invention. This is an annular pearl row formed in two rows in the axial direction as shown. In this case, the locking ring portion 4 is formed by brazing one end of each of the metal wire rods 3 penetrating the pearls 1 in each row to the folded back portion.

The connecting body 2 has a slightly wide width (axial dimension) corresponding to two rows of pearls, and two hemispherical concave portions 2C are formed at the ends.

Further, a substantially plate-shaped intermediate body 6 that connects the two rows of the metal wire rods 3 to each other is interposed at an appropriate position in the circumferential direction. The intermediate body 6 prevents the metal wire rods 3 in each row from being separated from each other in the axial direction, and at the same time, the intermediate body 6 is decorated or a jewel is attached to enhance the decorative effect. It is effective. The intermediate body 6 is also formed with a spherical concave portion 6B for improving compatibility with the adjacent pearl 1.

In this embodiment, an example of forming two rows of pearls has been described, but it is of course possible to form a ring or the like with a plurality of rows of pearls.

[0026]

[Effect of device]

 As described above, according to the present invention, the end portion of the metal wire that penetrates the plurality of pearls is folded back to form the locking ring portion by welding such as brazing, while the opening for inserting the locking ring portion is formed. A connecting body having parts at both ends is provided, and the locking ring portions at both ends of the metal wire holding the pearl are respectively inserted into the opening portions at both ends of the connecting body, and then both the locking ring portion and the connecting body are provided. The pearls on the metal wire and the connecting body are connected in an annular shape by inserting and fixing the pins so that the pearls penetrate through the connecting body without changing the quality of the pearls by the heat during welding. It is possible to form a ring or the like having high strength and an elegant appearance by connecting to.

When the pearls are formed in a plurality of rows, the strength of the ring or the like can be further increased and the workability can be improved. In addition, if an intermediate body that connects the metal wire rods in each row is interposed between the pearls that are adjacent to each other in the circumferential direction, the deformation of the pearls in each row that is connected in a ring shape is prevented. At the same time, the intermediate body can be used to enhance the decorative effect.

Furthermore, by providing both ends of the connecting body with concave shapes, it is possible to obtain an effect that the pearls adjacent to the connecting body can be settled down and the trouble of being rubbed against each other and being damaged can be prevented.
