Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a decorative device, for example, a decorative device used for a net dress or the like.

[Prior Art] Traditionally, in this type of device, stainless steel (hereinafter referred to as "stainless steel") was used as a tool for stringing pearls and other decorative items, instead of threads whose core material was silk or chemical fiber. Threads with metal cores such as fibers are used.

[Problems to be solved by the invention] Two examples of the use of netskuress using stainless steel thread will be described below.

<First Conventional Example> FIG. 4 is a perspective view showing an example of a main part of a necklace using stainless steel thread according to a first conventional example.
The necklace 100 shown in FIG.
A clasp 104 is used to connect 2,103. Since the fasteners 102 and 103 have similar configurations, the fastener 10 will be described below.
The second configuration will be explained. The stopper 102 is
A male threaded portion 105 and a female threaded portion 10 in a screwing relationship
6 and a decorative ring 107 that is loosely fitted onto the outer peripheral surface of the female threaded portion 106. A U-shaped pin 109 is passed through an O-shaped ring 108 provided on the clasp 104.
09 is the male threaded part 1 by caulking both ends.
It is attached to the 05 so that it does not come off. A female threaded portion 106 that is in a fitting relationship with this male threaded portion 105
As shown in FIG. 4, stainless steel thread 10
A stopper 110 is fixed to the tip of the stainless steel thread 101 by spot welding, and the tip of the stainless steel thread 101 is locked to prevent it from falling out of the female thread 106.

Next, attach the stainless steel thread 1 to one of the fasteners 102.
The procedure for stopping 01 will be explained. When stringing a plurality of pearls together using the necklace 100 having the above configuration, first, a predetermined number of pearls (such as pearls 111) are threaded through the stainless steel thread 101. The length of the stainless steel 101 is adjusted. When this work is completed, one end of the stainless steel thread 101 is locked to the female threaded portion 106 of the stopper 102 by a stopper 110. The female threaded portion 106 is screwed into the male threaded portion 105 of the stopper 102 connected to the clasp 104. At this time, the female threaded portion 106
A decorative ring 107 is loosely fitted onto the outer circumferential surface of. Next, the length of the stainless steel thread 101 is adjusted (cutting the surplus thread), and the length of the stainless steel thread 101 is adjusted.
The other end is fastened to the other stopper 103 in the same manner as the above-mentioned stopper 102.

In this way, the stringing of pearls using the Necklace 100 is completed, but this assembly requires welding techniques and welding equipment, making assembly and thread replacement a tedious task for an amateur. Furthermore, welding techniques are often outsourced to welding specialists, which has the drawback of increasing the cost of the work. Furthermore, once welding is performed, it becomes troublesome to readjust the length of the stainless steel thread 101.

<Second Conventional Example> FIG. 5 is a side sectional view showing another example of a main part of a necklace using stainless steel thread according to a second conventional example. The main parts of the netskures shown in Figure 5 are from the Showa era.
It shows the configuration of the "decoration device" of Utility Application No. 1983-42954 filed on April 1, 1963. In this idea,
A stainless steel thread 216 is used, which is a core material of stainless steel wire coated with vinyl in a vinyl tube 217. This stainless steel thread 2
16 is a ring 2 for threading the clasp (not shown)
15 once, and twice through the threading hole 213b of the stopper 213 by folding back. As shown in FIG. 5, the stopper 213 has a screw hole 213 connected to the thread hole 213b.
A is engraved. The screw head 212a of the set screw 212 passed through the threading hole 213a fixes the stainless steel thread 216 in the threading hole 213b in a pressed state. In this way, the set screw 212
Since the length of the stainless steel thread 216 can be easily adjusted with the , the length of the stainless steel thread 216 is superior to the first conventional example described above in that even an amateur can easily assemble the necklace. However, in the first conventional example, the stopper 102 only restricts the movement of the stainless steel thread 101 in the axial direction by the stopper 110, and the stopper 110 is rotatable in the axial direction. The rotational movement due to the twist of 101 is not restricted. On the contrary,
In the second conventional example, a method is used in which the stainless steel thread 216 is fixed in the stopper 213, so even if the necklace is assembled with the stainless steel thread 216 twisted, the stainless steel thread 216 cannot be removed from the stopper 213. Unless it is released, it will not untwist. This puts a strain on the stainless steel thread 216, resulting in a shortened service life.

<Third Conventional Example> In addition, as a third conventional example, Utility Application No. 155842 (1983) filed on October 11, 1985
There is a ball ring connector (No. 61910). This beaded ring connector is constructed so that the connecting portion serving as the seam looks like one of the beads connected to a string, forming an attractive beaded ring. That is, a ball ring coupling device is constituted by an engagement recess embedded and fixed in the ball body and an engagement protrusion that is loosely fitted into the ball body so as to be able to protrude outward. Connection and separation are possible by engaging and disengaging both the engagement recess and the engagement recess.

The structure of the above-mentioned ball ring connector not only allows connection and separation, but also allows each end of the string to be fixed, albeit indirectly, to one ball during connection.

Therefore, in the connected state, that is, in the assembled state, each end of the string is fixed to one ball, so it is impossible for the ends of the string to rotate relative to each other, and the string If the beads were connected in a twisted state, there was no other way but to disassemble the string and untwist the string, which was time-consuming.

The present invention was made in view of the above-mentioned drawbacks of the conventional example, and its purpose is to eliminate the twisting of the threads that occurred during assembly after assembly, in a structure that can be easily assembled and disassembled. Another object of the present invention is to provide a decorative device that can be easily returned by relative rotation of both ends of the thread.

[Means for solving the problem] In order to solve the above-mentioned problem and achieve the purpose,
The decoration device according to the present invention includes a thread in which a plurality of wires are covered with a tube having flexibility and elasticity;
a first stopper that locks one end of the thread; a second stopper that locks the other end of the thread;
A decorative device comprising: a clasp that connects a clasp to the first clasp in a threaded state; The clasp is provided with a storage part that has an opening with a diameter smaller than that of the flange and stores the vicinity of the tip of the projection in a loosely fitted state, and the protrusion stored in the storage part is arranged as a shaft. and the second stopper is pivotally supported by the clasp.

[Function] According to this configuration, the first stopper and the clasp are screwed together to fix the rotation of one end of the thread to the clasp, and the second stopper is loosely fitted to the clasp and is pivotally supported. By allowing the other end of the thread to rotate with respect to the clasp, relative rotation can be performed between the ends of the thread.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an external perspective view showing the structure of the necklace 1 of this embodiment, and FIG. 2 is a sectional view taken along the line A-A' showing the main parts of the necklace 1 shown in FIG. In the necklace 1 of this embodiment, as shown in FIG. 2, a stainless steel thread 10 is used as a thread (wire rod) for connecting a plurality of pearls. This stainless steel thread 10 has a structure in which a soft and flexible vinyl tube 12 is placed over the surface of a core material 11 which is made by bundling 36 stainless steel wires each having a diameter of 0.3 mm. With this configuration, the stainless steel thread 10
is endowed with durability against external forces such as tension, and has flexibility and flexibility similar to yarns made of fibers.

The necklace 1 of this embodiment uses a clasp 20 and a pair of fasteners 30, 40 to adjust and fix both ends of a stainless steel thread 10, on which a plurality of pearls are strung together, to a predetermined length. . The approximately spherical clasp 20 is made of a material suitable for decorative devices, such as gold, platinum, or crystal.
As shown in FIG. 2, a fitting portion 21 for fitting a cylindrical inserting body 50 is provided approximately at the center of the clasp 20. The fitting portion 21 and the fitting body 50 are prevented from coming off with an adhesive. The material of the entire fitting body 50 or a part of the material is not particularly limited as long as it is a metal having a hardness equal to or higher than that of the fasteners 30 and 40. A fitting body 50 fixed to the clasp 20 is provided with a connecting hole 52 therein in order to connect the pair of fasteners 30 and 40 in a row.

Here, the stoppers 30 and 40 and the fitting body 5
The configuration of 0 will be explained.

The fasteners 30 and 40 each have a cylindrical body. Shaft portions 36, 46 for connecting to the connecting hole 51 from both directions project from one end in the axial direction of each body. One shaft portion 36 has a length that allows it to be inserted slightly into the connecting hole 51, and the other shaft portion 46 has a length that allows it to be inserted over half the length of the connecting hole 51. The shaft portion 46 of the stopper 40 and the connecting hole 51 of the fitting body 50 are in a fixed relationship when connected. As shown in FIG. 2, a threaded engagement portion 47 is formed at the thick base portion of the shaft portion 46. As shown in FIG. A non-threaded part 53 is provided near one opening 23 of the connecting hole 51 of the fitting body 50 to be threaded into the threaded part 47 . On the other hand, the shaft portion 36 of the stopper 30 and the connecting hole 51 of the fitting body 50 are in a loosely fitting relationship when connected. As shown in FIG. 2, the shaft portion 36 has a flange portion 37 machined into a flange shape at the tip thereof. Near the other opening 22 of the connection hole 51 of the fitting body 50, there is a loose fitting part 51a through which the shaft part 36 is loosely inserted;
A storage section 51b that stores the flange section 37 is connected to the storage section 51b. Since the diameter of the flange portion 37 is larger than the diameter of the loose fitting portion 51a, the stopper 30
is prevented from coming off from the fitting body 50. That is, the stopper 30 and the clasp 20 have an integrated structure.

As a common configuration of the cylindrical fasteners 30 and 40, at the center of each axial direction of the cylindrical fasteners 30 and 40,
Threading holes 33 and 43 each having a diameter through which at least one stainless steel thread 10 can be inserted are provided. Taking the stopper 30 as a representative example, the threading holes 33, 43 are provided so as to also pass through the insides of the shaft parts 36, 46. Further, inside the fasteners 30, 40, as shown in FIG. 2, screw holes 34, 44 are provided which communicate with the threading holes 33, 43 from the outside at a substantially right angle. The screw holes 34, 44 and the setscrews 35, 45 are arranged so that when the entire body of the setscrews 35, 45 is housed in the screw holes 34, 44,
a is set so that it can press and fix the stainless steel thread 10 inserted through the threading holes 33 and 44. In this case, reference numerals 80 and 81 in FIG. 2 indicate the press-contact parts when the stainless steel thread 10 is fixed with the setscrews 35 and 45. As shown in Figure 2,
The front and rear surfaces of the fasteners 30 and 40 are provided with tapered portions 31, 32, 41, which widen toward the center of each main body.
42 are provided.

Here, the clasp 20 and the stopper 30 are integrated even though they are loosely fitted, and the flange 37 of the shaft 36 that creates the loosely fitted state connects the tip of the shaft 36. It is formed by caulking by pressing against the housing portion 51b of the hole 52. From this point of view, it is preferable that at least the storage portion 51b is made of a harder material than the shaft portion 51a.

Next, a method of assembling the necklace 1 of this embodiment will be explained.

Figures 3A to 3F show the net dress 1 of this embodiment.
It is a figure explaining the assembly procedure of.

In this embodiment, the clasp 20 and the stopper 30 are
Assembly (or installation) starts from the state in which these are integrated. First, one end of the stainless steel thread 10 is inserted through one stopper 30 (Fig. 3A),
One end of the stainless steel thread 10 is fixed to the stopper 30 by a set screw 35 (FIG. 3B). At this time, in the fixed state of the stainless steel thread 10, as shown in FIG. 2, the screw head 35a of the set screw 35 bites into the vinyl tube 12, so that the stainless steel thread 10 is pressed and locked (fixed). Next, the pearl 60 and the cushion material 70 for protecting the surface of the pearl are passed alternately through the other end of the stainless steel thread 10, and finally the stopper 40 is threaded through the other end of the stainless steel thread 10. Once the length of the thread has been adjusted and the length of the thread has been determined, the stainless steel thread 10 is fixed in the stopper 40 by the set screw 45 (FIG. 3C).

Next, the tip 46a of the shaft portion 46 of the stopper 40
The unnecessary stainless steel thread 10a that is protruding further is removed with a cutting tool such as scissors or a cutter (3D
), the threaded portion 47 of the stopper 40 is threaded with the non-threaded portion 53 of the fitting body 50. That is, the stopper 40 is pivotally fixed to the clasp 20. At this time,
If the stainless steel thread 10 is twisted, in order to correct the twist, the user should move the stopper 35 in the direction indicated by the arrow W (the opposite direction is also possible).
(FIG. 3E) relative to the clasp 20.

In this way, the assembly of the net dress 1 with no twist in the stainless steel thread 10 is completed (the third
(Fig. F), even if the stainless steel thread 10 is twisted during use, the twist can be easily corrected by the relative rotation of the stopper 30 and the clasp 20.

In addition, when changing the length of the stainless steel thread 10 or changing the thread, the clasp 20 and stopper 4
Since it only requires the effort of attaching and detaching from the 0, it can be easily handled even by an amateur.

Moreover, since each end of the stainless steel thread 10 is not exposed to the outside after assembly, the luxury quality and aesthetics of the necklace 1 are not impaired.

As explained above, according to this embodiment, even an amateur can easily perform assembly/disassembly work, and the twisting of the threads that occurs during assembly can be fixed without disassembling the assembly. , can be easily returned. In other words, it is possible to assemble the decorative device without worrying about twisting the threads.

In the above-described embodiment, the shape of the clasp 20 is spherical, but the present invention is not limited to this, and can be modified in various ways as long as it does not impair the beauty and luxury.

In addition, a connecting hole is arranged on the clasp 20 itself,
Even with a configuration in which the fasteners 30 and 40 are connected, the same effects as in the above embodiment can be obtained.

[Effect of the invention] As explained above, according to the invention of the present application, in a structure that can be easily assembled and disassembled, twisting of the threads that occurs during assembly can be easily corrected without disassembling even after assembly. It can be returned.
