Below, the chain for jewelry by this implementation is demonstrated based on drawing.
As shown in FIGS. 1A and 1B and FIG. 3, the chain for clothing according to the present embodiment is composed of a chain body 1 made of a noble metal material such as gold, silver, or platinum, and a stopper 2. Moreover, the one end side part 1a of the chain body 1 is a held part 5 of the stopper 2, and the stopper 2 is connected to the other end side part 1b of the chain body 1, and the held part By holding the fastener 2 at 5, an endless state in which the user can be dressed is obtained.

  The chain body 1 has a chain structure member 6 having a ring shape called a frame, which is continuously connected. Further, as the above-described chain component member 6, a so-called Kihei or Azuki type is used in the present embodiment. Further, the fastener 2 includes a spherical hollow part 4 made of a noble metal raw material and an elastic member 3 having a cylindrical shape. Among these, the hollow part 4 has a hollow portion into which the elastic member 3 is placed. Insertion holes 4a and 4b are provided at two locations where the inner peripheral surfaces of the peripheral wall face each other. Further, a circular ring 7 connected to the other end 1 b of the chain body 1 is welded to the outer peripheral surface of the peripheral wall of the hollow part 4. Further, the elastic member 3 is configured to pass the held portion 5 of the chain body 1 through the through-hole of the cylinder and hold it at an arbitrary position in the longitudinal direction of the held portion 5. In order not to be pulled out, it is molded from elastic silicon rubber.

  The held portion 5 held by the stopper 2 includes a plurality of chain constituent members 6 constituting one end side portion 1 a in the longitudinal direction of the chain body 1. In the present embodiment, an arbitrary number of chain constituent members 6 each having a length of about 1 to 2 cm when connected are dropped into an adhesive layer storing a powdery adhesive so that the chain constituent members 6 are connected to each other. The contact point is bonded and temporarily fixed with the powdery adhesive. Furthermore, as shown in FIGS. 2A to 2C, the one end side 1 a of the chain body 1 after temporary fixing is gripped by the gripping tool 12, and each gripping chain 12 is rotated and twisted while each chain is being twisted. By compressing the component member 6 and reducing the outer diameter, the gap between the connected chain component members 6 is reduced and is closely adjacent in an immobile state. As a result, an arbitrary number of chain constituent members 6 constituting the one end side portion 1a of the chain body 1 are formed into a non-rockable rod shape, and this non-rockable portion becomes the held portion 5 of the stopper 2.

Regarding the holding structure of the held portion 5 provided on the one end side portion 1a of the chain body 1 formed as described above and the stopper 2 connected to the other end side portion 1b of the chain body 1 as shown in FIG. A description will be given below based on a).
By inserting the held portion 5 of the chain body 1 into one of the insertion holes 4a and 4b of the stopper 2, the outer peripheral portion of the held portion 5 is elastic due to the elasticity of the elastic member 3 placed in the stopper 2. Is retained. Thereby, the held portion 5 of the chain body 1 is held by the pressing force due to the elasticity of the elastic member 3 of the stopper 2, so that it cannot be easily detached from the stopper 2. Further, since the held portion 5 has a certain length that can be arbitrarily set, even if an accident occurs in which the chain body 1 is unexpectedly pulled by the user wearing the chain for clothing according to the present embodiment. The stopper 2 is slightly slid in the longitudinal direction of the held portion 5 and does not fall off from the body. Further, since the held portion 5 has a structure that compresses a plurality of chain constituent members 6 constituting the one end side portion 1a of the chain main body 1, the surface of the outer peripheral portion of the held portion 5 becomes uneven. When the held portion 5 is held by the elastic member 3 in the stopper 2, the unevenness of the held portion 5 bites into the elastic member 3 and the stopper 2 is difficult to come off.

A second embodiment of the present invention will be described with reference to FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) to 5 (c).
4 (a) and 4 (b), FIGS. 6 (a) and 6 (b) of the third embodiment to be described later, and FIGS. 7 (a) and 7 (b) of the fourth embodiment, respectively. In the chain, the same part as in FIG. 3 of the first embodiment is shown in an enlarged manner.

  The chain for the body according to the present embodiment uses almost the same member as the first embodiment as the chain component 6 constituting the fastener 2 and the chain body 1, but the structure of the held portion 5 is different. It is. As shown in FIGS. 5A to 5B, the held portion 5 has a structure in which a cylindrical covering member 9 is covered on the outer peripheral portion of the one end side portion 1 a of the chain body 1. Further, when the held portion 5 of the stopper 2 according to the present embodiment is molded, a covering member 9 having a slightly larger diameter than the chain constituent member 6 is covered. And by compressing the outer peripheral part of said covering member 9 over the perimeter with the dice | dies 13 etc., the covering member 9 and the some chain | strand structure member 6 which the covering member 9 covers are compressed simultaneously, and a diameter is reduced. Squeezed. In addition, the outer diameters of the covering member 9 and the chain component member 6 after being compressed as described above are adjusted to be substantially the same as the outer diameter of the uncompressed portion of the chain body 1, thereby The appearance design of the chain body 1 and the held portion 5 has continuity.

  The jewelry chain formed as described above has the held portion 5 in a form in which the covering member 9 covers the one end side portion 1 a of the chain body 1. When holding the fastener 2 against the held portion 5, the elastic member 3 of the fastener 2 has the unevenness of the outer peripheral portion of each chain constituent member 6 and the covering member 9 straddling the unevenness. The held portion 5 having the smoothness of the surface due to the covering is held. Therefore, the holding force due to the elasticity of the stopper 2 and the peripheral wall of the covering member 9 guide the insertion and removal of the stopper 2 smoothly. A good chain for clothing can be provided.

  Further, as a third embodiment of the present invention, as shown in FIGS. 6A and 6B, a held portion 5 of a stopper 2 in which a covering member 9 is covered on an intermediate portion of one end side portion 1a of the chain body 1 is provided. Formed. The held portion 5 covers the covering member 9 in such a manner that only the outermost chain constituent member 6a is exposed from the one end side portion 1a of the chain main body 1, and only the range covered by the covering member 9 is on the outer peripheral side. The outermost chain constituent member 6a is prevented from coming off from the chain body 1 of the covering member 9, and other decorative parts (in this embodiment, the pulling wheel for connecting the other chain body 21) 11) The structure that doubles as the connecting means. The held part 5 formed in this way has the decorative member of the chain for decoration according to the present invention while the elastic member 3 is firmly attached over the entire circumference of the peripheral wall and maintains the holding state with the stopper 2. It can be developed in various ways. Thereby, it is possible to provide a high-value-added clothing chain that can be adapted to various clothes.

  Furthermore, the thing of Fig.7 (a) (b) provides the groove | channel 10 in the outer peripheral wall part of the coating | coated member 9 which comprises the to-be-held part 5 of the stopper 2 as 4th embodiment of this invention. . By providing the groove 10, when the held portion 5 is held by the stopper 2, the elastic member 3 of the stopper 2 bites into the groove 10, so that the stopper 2 comes off in the longitudinal direction of the held portion 5. It becomes difficult, and the fear of dropping off unexpectedly when using the jewelry chain according to the present embodiment is further eliminated.

  The chain for clothing according to the present invention compresses one end side part 1a of the chain body 1, compresses each chain constituent member 6 constituting the one end side part 1a, and allows the chain constituent members 6 to be arbitrarily set. Each of them may be formed into a rod shape that cannot swing. And the compression method of each chain | strand structural member 6 is based on the torsion using the holding tool 12 etc. like the said 1st embodiment, and the to-be-held part by die | dye 13 etc. like the said 2nd embodiment. In addition to squeezing over the entire circumference of the outer peripheral part 5, the plurality of chain constituent members 6 constituting the one end side part 1 a of the chain body 1 are compressed so that the respective connecting portions of the chain constituent members 6 do not swing. Any method can be used as long as the method can be fixed to. Further, the number of chain constituent members 6 to be compressed, the compressibility thereof, and the like are not limited as long as the connected chain constituent members 6 do not swing.
