Description

  The present invention relates to an ornament such as a ring, a necklace, a brooch and a bracelet to which a jewel is attached.

As such a decorative tool, Patent Document 1 proposes a ring in which two protrusions are provided on a ring-shaped support member and fixed so that a jewel frame is sandwiched with a screw in the center. The top of the jewel frame has pointed protrusions, and the front of the jewel part is related to the tilt angle of the finger by pressing the frictional resistance by supporting the jewel frame with screws on these points. It is always at the top due to gravity action, and it keeps shaking from side to side even with slight vibration.
Japanese Patent Laid-Open No. 2002-142817

  By the way, as described in Patent Document 1, when fixing the jewelry frame so as to sandwich the jewelry frame with the screws provided on the two protrusions, as described above, the front of the jewelry is always directed upward, and even with slight vibrations. In order to keep the jewelry frame from shaking, the pinching force by the screw cannot be increased too much.

  However, if the clamping force by this screw is small, the jewel will come off the support member together with the frame even if the jewel or jewel frame is inadvertently pressed against the support member side, or conversely pulled from the support member. May lose expensive jewelry. Further, if the jewel frame protrusions are simply supported by screws, it is difficult to keep the jewel frame always facing the upper part of the jewel frame that continues to sway from side to side even with slight vibration as described above.

  The present invention has been made under such a background, and while making the gem rockable, it can prevent a situation in which it is accidentally detached and lost, and more reliably the gemstone. It aims at providing the ornament which can be hold | maintained so that an upper surface part may face upward.

  In order to solve the above problems and achieve such an object, according to the present invention, a jewel is held by a holding member between a pair of opposing wall portions formed on a decorative body, and can swing freely. An attached ornament, wherein the holding member has an annular mounting portion on which the jewel is seated, and at least a pair of claws that are opposed to grip the jewel seated on the mounting portion. And a pair of connecting portions that are connected to the pair of wall portions and support the holding member in a swingable manner on the ornament body, and the at least one pair of claw portions sandwich the jewel. The direction is a direction substantially orthogonal to an imaginary line connecting the pair of connecting portions when viewed from the center line direction of the ring formed by the attachment portion.

  In the present invention, the holding member is further provided with a weight portion on the lower surface side of the jewel held by the holding member, and the center of gravity of the holding member holding the jewel is more than the imaginary line. It is also characterized by being positioned on the lower surface side.

  In the ornament of the present invention configured as described above, when the jewel or the holding member is inadvertently pressed or pulled, the holding member holding the jewel is connected to the pair of wall portions of the ornament main body, respectively. A force is applied so that the pair of connecting portions are pulled away from each other in the imaginary line direction, and accordingly, the annular attachment portion also has a ring as viewed from the center line direction of the ring formed by the attachment portion. In the direction extending in the direction, that is, in the direction substantially orthogonal to the imaginary line, the stress acts so that the mounting portion is flattened and the diameter of the ring is reduced.

  However, since at least a pair of claw portions are provided so as to sandwich the jewel in a direction perpendicular to the imaginary line of the mounting portion, the jewel is strongly sandwiched between the claw portions by such stress. Thus, the holding member is held more firmly. Therefore, according to the decorative tool of the present invention, even if the decoration is improved by supporting the holding member together with the jewel so as to be swingable by the connecting portion, the jewel or the holding member is pressed or pulled. It is not easy to remove the gemstones alone, and it is possible to prevent the loss of expensive gemstones.

  Further, if the holding member is further provided with a weight as described above so that the center of gravity of the holding member holding the jewel is positioned closer to the lower surface of the jewel than the imaginary line, the holding member swings. Also, the jewelry is provided with the weight portion, and is supported between the pair of wall portions of the accessory body so that the lower surface portion side of the jewelry faces downward. Therefore, this makes it possible to support the holding member so that the upper surface of a highly decorative jewel is more reliably directed upward regardless of the posture of the accessory body, and the jewel can be swung freely. Together with this, it is possible to provide an ornament that can attract the eyes of many people.

  1 to 5 show an embodiment in which the present invention is applied to a ring. That is, in this embodiment, the accessory main body 1 has a ring shape with a size that can be fitted into a finger, and a recess 2 is formed in a part of the outer peripheral edge of the accessory main body 1 around the recess 2. A jewel 3 is held by a holding member 4 and is swingably mounted between a pair of wall portions 2A facing each other and facing each other. Note that the ornament main body 1 is formed of a noble metal such as platinum, gold, or silver, particularly when the ornament is a ring as in the present embodiment.

  Various kinds of jewels 3 can be held. For example, the illustrated jewel 3 is a diamond, and generally has an upper surface 3A having a generally truncated cone shape with high decorativeness, which is cut, and the upper surface 3A. The bottom surface 3B of the substantially conical shape that tapers downward from the top is provided, and the outer diameter of the upper and lower surface portions 3A and 3B at the boundary portion 3C is the maximum outer diameter of the gemstone 3.

  The holding member 4 for holding such a jewel 3 is at least a pair of an annular mounting portion 4A on which the jewel 3 is seated and a pair of grips facing the jewel 3 seated on the mounting portion 4A. And a pair of connecting portions 4C that are connected to the pair of wall portions 2A of the accessory main body 1 and support the holding member 4 in a swingable manner on the accessory main body 1, respectively. Further, in the present embodiment, the holding member 4 is also provided with a weight portion 4D so as to be positioned on the lower surface portion 3B side of the jewel 3 that is seated on the mounting portion 4A and gripped by the claw portion 4B. The mounting portion 4A, the claw portion 4B, the connecting portion 4C, and the weight portion 4D are integrally formed of the same precious metal as that of the accessory main body 1, more preferably hard platinum that is hard to be damaged.

  Here, the attachment portion 4A has an inner diameter slightly smaller than the maximum outer diameter at the boundary portion 3C of the jewel 3, and has an annular shape centering on the center line O indicated by a broken line in the drawing. . Further, the claw portion 4B is a thin and small pin shape, and is formed in a "<" shape that extends obliquely upward from the outer periphery of the mounting portion 4A and then bends and extends obliquely upward inward. In the present embodiment, a pair of claw portions 4B so as to be located at the intersection of one diameter line L (shown by a one-dot chain line in the figure) passing through the center line O of the ring formed by the mounting portion 4A and the ring. Are provided so as to face each other in the direction of the one diameter line L so as to face the inside (center line O side).

  The jewel 3 is inserted into the holding member 4 from the upper side into the mounting portion 4A with the lower surface portion 3B facing downward with the claw portion 4B open to the outside. Next, the claw portion 4B is closed inward by being in contact with the inner periphery of the portion 4A, and then the claw portion 4B having a “<” shape is formed from the lower surface portion 3B and the outer periphery of the upper surface portion 3A. The lower part (boundary part 3C side) is hooked and held and held so as to be sandwiched in the one diameter line L direction.

  Further, in the present embodiment, the connecting portion 4C is an annular shape having a diameter that is extremely smaller than the annular shape formed by the attachment portion 4A. For example, such a small-diameter round can is formed on the outer periphery of the attachment portion 4A by laser brazing. By joining, it is integrally attached so that it may protrude to the outer peripheral side of this attaching part 4A. In addition, this connecting portion 4C also has a pair of connecting portions 4C and another diameter line (imaginary line M indicated by a two-dot chain line in the figure) passing through the center line O of the ring formed by the mounting portion 4A and the circle. It is provided on the opposite side to the center line O of the mounting portion 4A so as to be located at the intersection with the ring.

  On the other hand, the pair of wall portions 2A of the accessory main body 1 are provided with connected portions 2B to which the pair of connecting portions 4C are connected. These coupled portions 2B are also formed in a small-diameter annular shape, and are respectively disposed so as to protrude into the concave portion 2 by being joined or integrally formed with the protruding end portion of the wall portion 2B. Thus, the holding member 4 holding the jewel 3 is formed so that the connecting portions 4C are directed toward the wall portion 2A, and the connected portions 2B and the respective annular rings are slightly loosely combined to form a chain. By being connected, the jewel 3 is suspended from the connecting portions 4C at both ends in the recess 2 in a state where the upper surface portion 3A of the jewel 3 is directed to the outside of the ornament main body 1, so that it is generally around the imaginary line M. Is supported by the accessory main body 1 so as to be swingable.

  In this holding member 4, the direction in which the claw portion 4B sandwiches the jewel 3 is substantially the same as the virtual line M connecting the pair of connecting portions 4C when viewed from the direction of the center line O of the ring formed by the mounting portion 4A. The directions are orthogonal. In particular, in the ornament of the present embodiment in which the pair of claws 4B are arranged so as to sandwich the jewel 3 in the direction of the one diameter line L as described above, the one diameter line L and the imaginary line M are As shown in FIG. 4 and FIG.

  The weight portion 4D extends from the lower end to the lower side of the pair of claw portions 4B so as to be along a conical generatrix formed by the lower surface portion 3B of the jewel 3 protruding downward from the attachment portion 4A of the holding member 4. It extends in the direction of the center line O as it goes, and is formed in a V shape as shown in FIG. 3 connected at the lower end of the lower surface portion 3B on the center line O. And this weight part 4D is formed in the holding member 4 thicker than the other attachment part 4A, the nail | claw part 4B, and the connection part 4C, and the gravity center of the holding member 4 holding the jewelry 3 is a pair of connection. It is made to be located in the said lower surface part 3B side of the jewelry 3 rather than the said virtual line M which ties part 4C.

  In the ornament (ring) of the embodiment thus configured, first, the holding member 4 is swingably attached to the ornament main body 1 by the connecting portion 4C, and the jewel held by the holding member 4 3 also swings with the movement of hands and fingers, so that it gives off its sparkle, so it can add to the beauty of the jewel 3 itself and attract more people around it. .

  In particular, in the present embodiment, the weight 4D is provided on the holding member 4 as described above, and the lower surface of the jewel 3 is lower than the imaginary line M where the center of gravity of the holding member 4 including the jewel 3 is the center of oscillation. Since it is located on the side of the portion 3B, the holding member 4 is also supported so that the upper surface portion 3A side of the jewelry 3 is more surely upward in the state where the recess 2 is directed upward. become. Therefore, in such a state, the gem 3 can be swung while the upper surface portion 3A having high decorativeness is always attracting attention as described above, so that the surrounding attention can be more effectively collected. It becomes possible.

  In addition, in the holding member 4 of the present embodiment, the lower surface portion 3B is in contact with the annular mounting portion 4A and the jewel 3 is seated, so that the upper surface portion 3A of the jewel 3 is hidden by the mounting portion 4A. Since the claw portion 4B that is hooked on the upper surface portion 3A and holds the jewel 3 is also a thin and small pin shape, the high decorativeness of the upper surface portion 3A is impaired by the holding member 4. There is no need to do. Further, since the claw portion 4B has a small pin shape as described above, it is possible to minimize the jewel 3 from being damaged by the gripping by the claw portion 4B.

  Furthermore, in this embodiment, the pair of connecting portions 4C of the holding member 4 is formed in an annular shape by a circular can or the like, and the connected portion 2B provided on the wall portion 2A in the concave portion 2 on the accessory body 1 side is the same. The holding member 4 is swingably supported by the accessory main body 1 by connecting them in a chain. For this reason, the jewel 3 and the holding member 4 are not shaken in the recess 2 until, for example, upside down, and the upper surface portion 3A can be more reliably directed upward, and the jewel 3 is held together with the holding member 4. It is possible to prevent the accessory body 1 from falling off.

  Further, in the accessory of the present invention, the imaginary line M connecting the pair of connecting portions 4C in the holding member 4 and the one diameter line L direction in which the pair of claw portions 4B sandwich the jewelry 3 are connected to the mounting portion 4A. They are arranged so as to be substantially orthogonal to each other when viewed in the direction of the center line O of the ring formed. For this reason, if the jewel 3 or the holding member 4 is inadvertently pressed against the bottom side of the concave portion 2 or is pulled to the outside of the concave portion 2 on the contrary, the attachment portion 4A in which the connecting portion 4C is supported. Is pulled outward in the direction of the imaginary line M as indicated by the arrow A in FIGS. 4 and 5, while the mounting portion 4A is indicated by the arrow B in the direction of the one diameter line L. It will receive the stress pressed inward. That is, when the jewel 3 and the holding member 4 are pressed or pulled in this manner, the attachment portion 4A having an annular shape in this embodiment has a long axis on the imaginary line M and a short on one diameter line L. Stress is applied to deform into an ellipse having an axis.

  However, since the one diameter line L direction is a direction in which a pair of claw portions 4B are provided and the jewel 3 is sandwiched, the jewel 3 is more firmly bonded to the claw portion 4B by such a stress. And is held by the holding member 4. Therefore, according to the decorative tool of the present invention, even if the holding member 4 itself becomes unstable by attaching the holding member 4 so as to be swingable in order to enhance the decoration, as described above, Since the jewel 3 is not easily detached from the holding member 4 when the holding member 4 is pressed or pulled, the expensive jewel is coupled with the fact that the holding member 4 is prevented from falling off as described above. It is possible to prevent a situation where 3 is lost.

  In the present embodiment, as described above, the pair of claws 4B are arranged on one diameter line L to hold the jewel 3, but for example, this one diameter line L and the annular mounting portion 4A are arranged. A plurality of claw portions 4B may be provided around the diameter line L at at least one intersection with the claw portion 4B, and the jewel 3 may be sandwiched between the opposing claw portions 4B. Further, the shape of the ring formed by the mounting portion 4A may be an elliptical ring, a square, a rhombus, or a polygonal ring of pentagon or more, according to the shape of the jewel 3 to be seated. Furthermore, although this embodiment demonstrated the case where this invention was applied to a ring, of course, it is possible to apply this invention also to other types of ornaments, such as a necklace, a brooch, and a bracelet.

It is a side view showing one embodiment at the time of applying the present invention to a ring. It is an enlarged side view of the periphery of the recessed part 2 in embodiment shown in FIG. It is the expanded side view which looked at the holding member 4 holding the jewelry 3 in embodiment shown in FIG. 1 from the imaginary line M direction.
