  In this way, in an accessory equipped with a plurality of decorative objects having different decorative properties, for example, if the decorative objects can be pivotably connected to each other via an axis, and a state in which the decorative objects are rotated at a predetermined angle can be maintained. , You can give variations to decorations. However, when the decorative objects are connected to each other using the technique of Patent Document 1, even if the decorative objects are rotated to a predetermined angle, the state cannot be maintained.

  On the other hand, for example, a shaft core having one end fixed to an arbitrary ornament is fitted into a through hole of another ornament, and a male screw with a hook is fastened to a female screw formed on the other end of the shaft core. In addition, a certain holding force can be obtained by pressing the decorative objects together. However, since the decorative object is generally formed of a noble metal or the like, if the rotation is repeated while being in contact with each other, the contact surface may gradually wear and the holding force may be reduced.

  An object of the present invention is to provide an accessory capable of maintaining a high holding force even when the ornament is repeatedly rotated.

  In order to solve the above-mentioned problems, the present invention provides an accessory in which another ornament is rotatably supported on one ornament, a cylindrical core rod whose one end is fixed to the ornament, and the core The other end of the rod is provided with a male screw with a hook that is screwed into a female screw coaxially provided on the other end of the rod, and the other decorative object is formed with a through-hole into which the core rod or the body of the male screw is fitted. A core rod or body portion is inserted into the through hole, and a male screw is screwed, and an annular elastic member is provided on the outer peripheral side of the core rod between one ornament and another ornament. It is characterized by being sandwiched.

  According to the present invention, since the other decorative object is supported by the core rod or the like with the elastic member pressed, for example, one decorative object has a predetermined elastic force according to the deformation of the elastic member. Works. For this reason, even if one decorative object is rotated, a holding force capable of always maintaining the state can be obtained. In addition, since one decorative object and another decorative object are not in direct contact with each other, even if they are repeatedly rotated, the metal decorative object is not worn, and a predetermined holding force is maintained for a long time. be able to.

  Furthermore, the present invention provides an accessory in which a plurality of other ornaments are rotatably supported on one ornament, and a cylindrical core rod whose one end is fixed to the one ornament, A male screw with a hook that is screwed into a female screw coaxially provided on the end side, and a through hole into which the core rod or the body of the male screw is fitted is formed in another decorative object. A core rod or body is inserted, and a male screw is screwed, and on the outer peripheral side of the core rod, between one ornament and another ornament, between other ornaments, An annular elastic member is sandwiched.

  In this way, even in a jewelry provided with a plurality of other ornaments, a predetermined elastic force acts on all ornaments, so that even if each ornament is rotated independently, the state can be maintained. it can.

  In this case, the elastic member is preferably formed of a plastic, particularly a polyacetal resin. In general, polyacetal resins are excellent in elastic properties, creep resistance and fatigue resistance, and have good self-lubricating properties. For this reason, if it uses as an elastic member of this invention, while producing high elastic force, the progress of wear can be suppressed and it functions suitably.

  Moreover, it is preferable that an annular metal member is disposed on the outer peripheral side of the elastic member. Thus, by providing a metal member, it can prevent that an elastic member is visually recognized from the clearance gap between ornaments, and aesthetics can be maintained.

  According to the accessory of the present invention, a high holding force can be maintained even when the ornament is repeatedly rotated.

  Hereinafter, embodiments of a jewelry according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view for explaining the configuration of a connecting portion of a clothing accessory to which the present invention is applied. FIG. 2 is an external view showing an aspect of a jewelry to which the present invention is applied. FIG. 3 is an external view showing another aspect of the accessory to which the present invention is applied.

  The accessory according to the present embodiment is configured by rotatably connecting three decorative objects (for example, hoop structures) having different decorative properties, and the decorative chain is inserted into a Vatican formed integrally with an arbitrary decorative object. For example, it can be used for pendants, necklaces, earrings, and the like.

  The ornament is composed of a first hoop 1, a second hoop 3, and a third hoop 5, all of which are formed in an annular shape using an arbitrary noble metal such as gold, silver, or platinum. Each hoop is rotatably connected to another hoop at a connecting portion 7 formed at one end thereof. The first hoop 1 is formed with a Vatican 9 through which the decorative chain 11 is inserted through the connecting portion 7. The second hoop 3 and the third hoop 5 are adjacent to the first hoop 1. Concatenated in order.

  In the present embodiment, the first hoop 1 is mainly intended to exhibit a metallic luster and is not provided with jewelry or the like. On the other hand, in the second hoop 3, jewelry 13 is attached to the surface on the front side (arrow a) of the hoop at a predetermined interval, and the third hoop 5 has jewelry 15 along the inner peripheral surface of the hoop. Is installed. A jewelry 16 is attached to one surface (surface) of the connecting portion 7. In addition, each hoop may be formed with the same material, and may be formed with a different material.

  Each hoop rotates in the connecting portion 7 with the center line b as the center of rotation. FIG. 2 shows a state in which the rotational positions of the respective hoops are made coincident with each other. FIG. 3 shows that the second hoop 3 and the third hoop 5 are rotated in the opposite directions by the same angle with the first hoop 1 as a reference. It represents the state of being moved. Thus, the arrangement of each hoop can be determined as appropriate.

  Next, the structure of the connection part 7 to which this invention is applied is demonstrated using FIG.

  A lower side (arrow a) of FIG. 1 represents the front side of FIG. The connecting portion 7 includes a cylindrical core rod 17, a male screw 19, elastic members 21a to 21c, and washers 23a and 23b. A stepped recess is formed on the back surface of the third hoop 5, that is, the surface on the first hoop 1 side, and this recess has an annular elasticity around the mounting surface 25 to which the core rod 17 is fixed. It has the attachment surface 27 in which the member 21b is arrange | positioned. One end surface of the core rod 17 is brazed to the mounting surface 25, and a female screw is formed coaxially on the other end surface. A stepped hole is formed in the second hoop 3, and the stepped hole has a mounting surface 31 on which an annular elastic member 21 a is disposed around a through hole 29 through which the core rod 17 is inserted. Yes. Further, a stepped hole is formed in the first hoop 1, and the stepped hole has a storage portion 37 for storing the flange portion 35 around the through hole 33 through which the body portion of the male screw 19 is inserted. Yes. Further, annular washers 23a and 23b are arranged on the outer peripheral sides of the elastic members 21a and 21b so as to surround them. The washer 23 is for preventing the elastic member 21 from being visually recognized from the gap between the hoops. An annular elastic member 21 c is provided between the storage portion 37 of the first hoop 1 and the flange portion 35 of the male screw 19.

  As a material for forming the core rod 17, the male screw 19, and the washer 23, noble metals such as gold, silver, and platinum are preferably used as in the case of the hoop, but other metal materials, for example, alloys such as stainless steel are used. Also good.

  The elastic member 21 is formed by molding and processing a polymerization type such as a thermoplastic resin, in particular, a polyacetal resin, as a material having elasticity. The polyacetal resin is excellent in elastic properties, creep resistance, fatigue resistance, solvent resistance, etc., and has good self-lubricating properties. For this reason, while exhibiting high elastic force, since it is slidable and can suppress progress of wear, it functions suitably as the elastic member 21 of the present embodiment. As the polyacetal resin, for example, “Derlin (registered trademark)” manufactured by DuPont can be used.

  Next, an example of the assembly procedure of the connecting portion 7 configured as described above will be described.

  First, the elastic member 21b is arranged around the core rod 17 fixed to the third hoop 5, and the washer 23b is arranged around the elastic member 21b. Next, the core rod 17 is inserted into the through-hole 29 of the second hoop 3, the elastic member 21a is disposed around the inserted core rod 17, and the washer 23a is disposed around the elastic member 21a. Next, the male screw 19 fitted with the elastic member 21 c is inserted into the through hole 33 of the first hoop 1, and the male screw 19 is fastened to the female screw of the core rod 17. It should be noted that the amount by which the male screw 19 is tightened is regulated by the length of the core rod 17.

  Here, the installation height of the elastic members 21a and 21b installed in the respective hoops (before the male screw 19 is tightened) is at least higher than the installation height of the washers 23a and 23b. For this reason, when the male screw 19 is tightened, each hoop presses the elastic member 21 in the thickness direction without contacting the washer 23. For this reason, a predetermined magnitude of elastic force according to the elastic deformation caused by the pressing of the elastic member 21 acts on the upper and lower hoops. In other words, the holding force for holding each hoop can be adjusted by adjusting the tightening amount of the male screw 19.

  On the other hand, the male screw 19 fitted into the core rod 17 has the back surface (back surface) of the flange portion 35 on the same surface as the surface of the first hoop 1 or a position lower than the surface, and the flange portion 35 is the storage portion. It will be in the state of being accommodated in 37 spaces. Here, the male screw 19 is appropriately subjected to rotation prevention measures, and is fixed with, for example, a known adhesive.

  In the present embodiment, the core rod 17 is inserted into the through hole 29 of the second hoop 3, and the body portion of the male screw 19 is inserted into the through hole 33 of the first hoop 1. For example, the core rod 17 may be formed so as to be inserted into the through hole 33 of the first hoop. In short, it is sufficient that the flange portion 35 of the male screw 19 is configured to tighten the first hoop 1.

  As described above, according to the present embodiment, in an accessory provided with a plurality of hoops as an ornament, the elastic member 21 is disposed on the outer peripheral side of the core rod 17 serving as the shaft core, and the elastic member is disposed between the hoops. Therefore, even if each hoop is rotated to an arbitrary position, the state can always be held with a predetermined holding force. Further, since the hoops do not directly contact each other, even if the hoops are repeatedly rotated, wear does not occur and a predetermined holding force can be maintained for a long time.

  Further, in the present embodiment, the configuration including three hoops as an ornament has been described as an example. However, for example, in the configuration including two or four or more hoops, the same effect can be obtained by applying the present invention. Can be obtained. Moreover, in this Embodiment, since the cyclic | annular member made from a noble metal is arrange | positioned on the outer peripheral side of an elastic member so that an elastic member cannot be seen from the clearance gap between hoops, aesthetics are not impaired.

  Since the accessory of the present embodiment can rotate a plurality of ornaments and hold them in arbitrary positions, various ornamental variations can be expressed according to the user's preference, Decorative value can be increased.

It is sectional drawing explaining the structure of the connection part of the accessory which applies this invention. It is an external view which shows the one aspect | mode of the jewelry which applies this invention. It is an external view which shows the other aspect of the jewelry which applies this invention.
