In this decoration device, a screw is engraved in the threading hole of the wire thread stopper, and a set screw is screwed into the threading hole, and the wire thread folded back on the clasp side is fixed by pressing force at the tip of the screw. ing. However, this structure is characterized in that it is releasably fixed by the structure of the screw hole and the set screw. Therefore, a structure for releasable fixing becomes indispensable and the size becomes large. It has the drawback of becoming larger. On the other hand, as a structure for stopping the thread that is folded back on the clasp side and inserted in the reciprocating double thread, there is known a continuous string thread stopping structure of the accessory of Japanese Utility Model Publication No. 57-60340. Since this is caulked and the locking cylinder is further inserted into the cover cylinder, there is a drawback that the structure becomes complicated. In addition, as a structure in which the thread is passed through the wire thread stopper in a double manner, there is known a structure in which a hole through which the thread is passed is crushed or a filler is put in the hole and fixed, as in Japanese Utility Model Laid-Open No. 59-23316. There were some defects such as the shape of the wire thread stopper was deformed, and the work for fixing was troublesome.

The present invention has been made in view of the above circumstances, and its main problem is to fix the wire thread to the wire thread stopper simply by fitting the fixing pin into the attachment hole of the wire thread stopper. The object is to provide jewelry that can be used. Another object of the present invention is to provide an accessory that facilitates the work of fixing the wire thread with the wire thread stopper.

[0005]

[Action]

 The protrusion of the fixing pin that fits into the mounting hole is slightly outward of the mounting hole, and the protrusion is pressed firmly against the inner wall of the mounting hole and is also crushed when it is fitted into the mounting pin. The gaps are filled, forming wedges and increasing the fixing force between the mounting hole and the wire thread stopper. Further, if the concave portion is provided, the tip of the fixing pin presses the wire yarn into the concave portion, and the wire yarn is pressed by the fixing pin while being bent along the concave portion. As a result, the pulling force of the wire thread can be increased even if the pressing surface against the fixing pin is narrow. In this way, the wire thread can be firmly fixed even if the fixing pin is thin, so the wire thread stopper can be downsized, and the fixing thread can be simply pushed into the mounting hole. Can be fixed. In addition, the protrusion is inserted near the opening of the mounting hole at a position where the tip of the fixing pin does not protrude into the threading hole when the fixing pin is inserted into the mounting hole, so the fixing pin is in the standby state. The wire thread can be passed through the threading hole while it is held and attached to the wire thread stopper. When fixing the wire thread, the fixing pin is pushed into the threading hole to press the wire thread into the recess, but the protruding portion is pressed by the peripheral wall of the mounting hole and is crushed while advancing through the mounting hole and the mounting hole. Since it stays inside, it is firmly fixed. Further, the fixing force can be adjusted by the protrusion amount (diameter) and the length of the protrusion.

【Example】

 A preferred embodiment of the accessory according to the present invention will be described below with reference to the drawings. The accessory 1 shown in FIG. 1 and FIG. 2 uses a clasp 10 shown as an example of a fastener, and a decorative body 3 is passed through a wire thread 2 and the end portion side of the wire thread 2 is fixed to the wire thread. The wire thread 2 is passed through the threading hole 5 formed through the tool 4, passed through the clasp 10 side, folded back, and passed through the threading hole 5 from the opposite direction, and the wire thread 2 reciprocally inserted into the threading hole 5 is inserted. It has a structure in which a fixing pin 8 is fitted and fixed in a mounting hole 6 of the wire thread stopper 4.

In this embodiment, the wire yarn 2 has a known structure in which a stainless steel wire is used as a core material and a flexible synthetic resin coating material (for example, a vinyl cover) is coated. As the ornamental body 3, a gem such as a pearl is illustrated as shown in FIG. 1, but a large number of the ornamental bodies 3 are connected by the wire threads 2. The clasp 10 has a publicly-known configuration including a pair of detachable component pieces, and a ring 10a is integrally fixed to each component piece, and one or a plurality of thread hooking rings 11 are attached to the ring 10a. It is connected. In this embodiment, the thread hooking ring 11 serves as the folding means, but it may be a ring 10a integrally formed with the clasp 10.

Next, the wire thread stopper 4 is made of a metal material. As shown in FIGS. 2 and 3C, the thread threading hole 5 penetrating the center and the threading hole 5 are communicated with each other. A mounting hole 6 is formed on one side that is substantially orthogonal to the mounting hole 6. Further, the wire thread stopper 4 in the illustrated example is curved so that one side adjacent to the gemstone is spherically recessed. Here, the threading hole 5 has a circular cross section, and is set to a size such that at least the folded and doubled wire thread 2 can be inserted. The mounting hole 6 has a circular cross section and is arranged so as to be orthogonal to the threading hole 5 as described above.

Further, a recess 7 is formed in the inner wall of the threading hole 5 at an extension position of the mounting hole 6. The recess 7 is formed in a substantially V-shaped cross section so that the entire shape or the shape of the tip is bent in the extending direction of the threading hole 5. In the case of the illustrated example, the concave portion 7 is a conical recess, which can be easily formed by the tip of the drill when the mounting hole 6 is drilled. However, in this invention, the shape of the concave portion 7 is not limited to the above-mentioned embodiment, and any shape such as a cross-sectionally inverted U-shape may be used as long as it is bent and fixed when the wire thread 2 is pressed by the fixing pin 2. The concave portion 7'shown in FIG. 4 has a hole having the same cross-sectional shape as the mounting hole 6 and the tip thereof is formed in a V-shaped cross-section, which enhances the insertion degree of the fixing pin 8 and increases the bending of the wire thread. Therefore, it can bear a large load. Other configurations are the same as those in the above-mentioned embodiment.

On the other hand, as shown in FIG. 3A, the fixing pin 8 fitted in the mounting hole 6 has a main body 8a slightly smaller than the diameter of the mounting hole 6, and a smaller diameter than the main body 8a. The main body 8a is formed with a protruding portion 9 that projects slightly outward from the cross section of the mounting hole 6 in the middle of the main body 8a. In this embodiment, the protrusion 9 is an annular protrusion that protrudes in a strip shape along the outer peripheral surface of the main body 8a.

In this embodiment, the position of the protrusion 9 is such that the tip of the fixing pin 8 does not protrude into the threading hole 5 when the fixing pin 8 is inserted into the attachment hole 6. 6 is inserted in the vicinity of the opening (see FIG. 4), and when the fixing pin 8 plunges into the threading hole 5 and presses the wire thread 2, the projection 9 is set to a position where it stays in the mounting hole 6. (See Figure 2). Because of the above-mentioned configuration, when molding the accessory 1, first, the decorative body 3 is passed through the wire thread 2. On the other hand, the fixing pin 8 is inserted into the attachment hole 6 of the wire thread stopper 4. At this time, the fixing pin 8 is inserted to a position where the protrusion 9 is fitted in the vicinity of the opening of the mounting hole 6.

As a result, the fixing pin 8 is held in the mounting hole 6 and stands by at a position where the tip does not enter the threading hole 5 (see FIG. 4). Then, the ends of the wire threads 2 are passed through the threading holes 5 of the wire thread stopper 4, respectively, passed through the thread hooking ring 11 connected to the clasp 10 and folded back, and the wire thread stopper is pulled from the opposite direction. The wire thread 2 is passed through the thread threading hole 5 of No. 4 to set the wire thread 2 to a predetermined length. After that, the fixing pin 8 is pushed further strongly, and the tip of the wire pin 2 is inserted into the threading hole 5 in a reciprocating double manner. At the same time, the protrusion 9 further enters the mounting hole 6.

That is, in the fixing pin 8 fitted in the mounting hole 6, the protrusion 9 is set to have a diameter slightly larger than the cross section of the mounting hole 6, so that the protrusion 9 is strongly attached to the inner wall of the mounting hole 6. Since it is pressed and fitted while being crushed, the gap between the mounting hole 6 and the fixing pin 8 is filled, and the fixing force is increased. At the same time, the pressing portion 8b at the tip of the fixing pin 8 presses the wire yarn 2 into the concave portion 7, so that the wire yarn 2 is bent along the concave portion 7 into a substantially doglegged shape by the fixing pin 8. It is pressed (see FIG. 2). As a result, even if the pressing force of the pressing portion 8b of the fixing pin 8 is smaller than that by screwing or the like, it is possible to increase the pulling force against the wire thread by pressing the wire thread 2 while bending it.

In the embodiment described above, the fixing pin 8 has the pressing portion 8b set to have a small diameter to facilitate the insertion into the mounting hole 6, but as shown in FIG. It may have substantially the same diameter as the main body. In this case, the tip edge portion is preferably chamfered in a tapered shape so that it can be easily inserted into the mounting hole 6. Further, the wire thread stopper 4 shown in FIG. 5 shows a further downsized shape, and is the same as the embodiment of FIG. 4 with a structure in which the recess 7 ′ is set deep. Further, the fixing pin 8 ′ has a frustoconical shape in which a tapered pressing portion 8b ′ on the tip side is gradually smaller in diameter than the main body 8a ′, and is configured to be easily inserted into the recess 7 ′ side. .

The wire thread stopper 4 shown in FIG. 6 is the same as the above embodiment except that it does not have a recess. Further, the fixing pin 8'has a protrusion 9'at substantially the center thereof, and a tooth portion 8c is provided at the tip of the pressing portion. The other components that are the same as those in the above-described embodiment are designated by the same reference numerals and the description thereof is omitted. Also in this case, the tooth portion 8c of the fixing pin 8 can press the wire thread and firmly fix it. Here, the tooth portion 8c is not limited to one having a sharpened tip, and may have an inverted ladder shape in cross section or a convex or concave shape such as a structure in which one or more grooves are formed at the tip of a fixing pin. It may be. Alternatively, the pressing portion of the fixing pin may be a flat surface and tooth portions may not be provided, and the wire thread may be directly pressed and fixed.

FIG. 7 shows a different embodiment in which the protrusion 9 ′ of the fixing pin 8 ′ has a diameter slightly larger than the mounting hole 6 from the middle position of the fixing pin 8 ′. Below the protruding portion 9'of the fixing pin 8 ', a shaft body 8a' having a diameter slightly smaller than that of the mounting hole 6 and a frustoconical pressing portion 8b 'are formed at the tip thereof. Also in this case, similarly to the above-described embodiment, when the fixing pin 8 ′ is inserted into the mounting hole 6, the protrusion of the pressing portion 8 b ′ does not protrude into the threading hole 5 in the vicinity of the opening of the mounting hole 6. When a part of 9 ′ is inserted and the fixing pin 8 ′ is held without wobbling, and is further pushed in, when the fixing pin 8 ′ is pushed into the threading hole 5 from the tip side and the wire thread is pressed. The main part of the protrusion 9 ′ stays in the mounting hole 6 and the fixing force can be increased.

The fixing pin 8 ′ shown in FIG. 8 has a shape configuration in which the projection 9 ′ has a diameter slightly larger than the mounting hole 6 from the middle position of the fixing pin 8 ′ as in FIG. 7. The lower half portion is composed of a pressing portion 8b 'formed in a taper shape having a gradually smaller diameter from below the protruding portion 9'and a tooth portion 8c' formed at the tip thereof and having a smaller diameter. There is. Here, the tooth portion 8c 'may not be provided, and only the protrusion 9'and the pressing portion 8b' may be configured. In this case as well, the same as in the previous embodiment, and since the upper end of the pressing portion 8b 'having a tapered cross section is connected to the projection 9', it can be easily inserted into the mounting hole 6. Incidentally, as shown in FIGS. 7 and 8, it is preferable to form the recess 7 ′ in the wire thread stopper 4 because the tightening fixing force can be increased. However, in this invention, the fixing force can be obtained without providing the concave portion.

In addition, in the structure shown in FIG. 2, as a result of conducting a test according to the tensile test method of the metal material of JISZ2241, as a result, the diameter of the mounting hole was 1 mm, the diameter of the fixing pin was 0.95 mm, and the length was It has been confirmed that a load of more than 6 kg is withstood when the diameter of the protrusion is 1.04 to 1.07 mm and the width of the protrusion is 0.2 to 0.3 mm. Further, if the structure is such that the recess 7'is deep as shown in FIGS. 4, 5, 7 and 8, it is possible to withstand a larger load. In addition, when pressing with a fixing pin without providing a recess as shown in FIG. 6, it is possible to withstand the above load, but it is possible to withstand a sufficient load as an accessory, and if a tooth portion is formed in the pressing portion, it will be larger. It was confirmed to withstand the load.

In the present invention, the ornamental body is not limited to the gemstone, but may be anything that is connected to the wire thread and used for the accessory, and is not limited to the above embodiment. Further, the protrusion is not limited to the strip shape, but may be one or other spherical protrusions protruding at equal intervals along the outer periphery, and the lower side is gradually narrowed so that it can be easily inserted into the mounting hole. Preferably. The recess may be a recess in which the wire thread pressed by the fixing pin is bent at least partially.

Further, if the position of the protrusion on the fixing pin is such that it stays within the mounting hole when fixing the wire thread, the tip of the pressing part will not enter the mounting hole just before it is inserted into the threading hole. Even if it is set to the position, at least the wire yarn can be firmly fixed, so the protrusion may be set to a position slightly above the fixing pin. Further, a small-diameter auxiliary hole may be provided which is opened at the bottom surface of the wire thread stopper and extends along the center line of the attachment hole and communicates with the threading hole (recessed portion if a recessed portion is formed). If a pin or the like is pushed through this auxiliary hole and pushed up strongly, the fixed pin that has been crimped can be removed. In addition, it goes without saying that various design changes can be made without changing the gist of the present invention.

[Effect of device]

 According to this invention, when fixing the wire yarn, the fixing pin is provided with a protrusion, and the protrusion can be crushed and firmly fitted into the mounting hole to firmly fix the wire yarn. If the tip of the fixing pin is inserted into the mounting hole and the tip does not protrude into the threading hole and it can be held at a position where it does not interfere with the insertion of the wire thread, it can be done easily when the fixing pin is pushed harder for fixing. be able to. Also, if a recess is provided in the inner wall of the threading hole of the wire thread stopper, and the wire thread is bent and pressed by the fixing pin, a strong fixing force can be obtained even if the pressing surface is narrow, and at the same time it can be fitted into the fixing pin. Since only the protrusion that is crushed when it is inserted is provided, the mounting hole can be set small, and the wire thread stopper and the wire thread stopper can be downsized without reducing the fixing force.
