Description

  The present invention relates to a decorative ring.

  Generally, when purchasing a ring, the number of the ring is determined based on the thickest part (for example, the second joint) of the finger to be worn.

  However, since the finger thickness tends to edema in the evening rather than in the morning, it may take time to remove the ring. In addition, a person suffering from rheumatism or the like does not have freedom of finger joints and may be painful when the ring passes through the second joint or the like.

  Therefore, the ring is composed of two arc-shaped first arc-shaped portions and second arc-shaped portions, and one end portions thereof are rotatably connected to each other, and the second arc-shaped portion is connected to the other end portion of the first arc-shaped portion. A third arcuate portion that is slidable along a guide groove formed along the inner peripheral surface of the sleeve is connected, and the elastic locking member is pushed into the guide groove with the third arcuate portion being inserted into the guide groove. Thus, a ring for locking the third arc-shaped portion in the guide groove has been proposed (see Patent Document 1).

  According to this, since the inner diameter of the ring can be freely adjusted by the length of the third arc-shaped portion inserted into the guide groove, the ring can be easily removed. However, since the third arcuate portion and the elastic locking member are exposed from the ring when the ring is mounted, the appearance is deteriorated.

  On the other hand, a ring is constituted by two arc-shaped ring pieces, one end portions of these ring pieces are rotatably connected, and along the inner peripheral surface of one end portion of one ring piece. There has been proposed an accessory that presses the tip of the attached leaf spring against the inner peripheral surface of one end of the other ring piece to urge the other ends of the two ring pieces closer to each other. (See Patent Document 2).

  When the structure of Patent Literature 2 is applied to a ring, the problem of aesthetics does not occur because the spring becomes invisible when worn. However, in a state where it is removed from the finger, the spring is exposed from the inner peripheral surface of the ring, so that it looks bad. In addition, for example, when a metal spring contacts the skin for a long time, there is a concern about problems such as metal allergy.

  An object of the present invention is to provide a decorative ring having a good appearance.

  In order to solve the above-mentioned problems, the decorative ring of the present invention is capable of rotating with two ring pieces forming the ring and one end portions of the two ring pieces as a center axis parallel to the axis of the ring. A connecting pin to be connected, a spring member for urging two ring pieces whose ends are connected to each other in a direction approaching each other, and communicating with the inside of one end of the two ring pieces along the ring pieces, respectively. The spring member is housed in the space portion so that both end portions can press the inner wall of the space portion at a position where the connecting pin is sandwiched.

  According to this, since the spring member accommodated in the space portion can be surrounded by the wall of each ring piece, the spring member is not exposed at all from the ring, and the appearance can be improved. Moreover, since the spring member is pressing the inner wall of each ring piece located in the space part on both sides of the connecting pin, the ring pieces can be urged toward each other. As a result, the inner diameter of the ring can be freely changed.

  In this case, a leaf spring can be used as the spring member. For example, both end portions extending from the coil portion wound in a coil shape are formed so as to be able to contact the inner wall of the space portion, and the coil portion. Can be loosely fitted to the connecting pin. According to this, since the spring member is accommodated in the space while being supported by the connecting pin, it is possible to prevent the displacement of the spring member and to continuously generate a predetermined spring force. Moreover, an assembly property can be improved by letting a connection pin pass through the coil part of a spring member.

  In addition, the two ring pieces have slits formed at one end of one ring piece, and both sides sandwiching the slit serve as support parts for supporting the connecting pin, and at one end of the other ring piece, A protrusion is formed which is inserted into the slit and is loosely fitted to the connecting pin. The protrusion is positioned at the space of one ring element, and the two ring elements are connected via the connecting part. It can be formed so as to be able to regulate the rotation angle by contacting the inner wall of the space when it rotates.

  According to this, since the front end portion can be in contact with the inner wall of the space portion, the operation range between the other end portions of the two ring pieces can be limited, and thus damage due to excessive rotation of the ring pieces can be prevented. At the same time, the other end portions can be easily aligned.

  In addition, the two ring pieces can be formed such that the other end portions can be engaged with each other.

  According to this, since the other ends of the ring pieces can be supported with each other, it is possible to prevent the decoration ring from being deformed due to the positional deviation between the other ends.

  Further, the two ring pieces can be formed such that the other end portions are respectively formed in an annular shape, and the other end portions are gently connected to each other.

  According to this, since the division surface where the other ends of the ring pieces abut can be made inconspicuous, the appearance can be improved.

  According to the present invention, it is possible to realize a decorative ring that prevents the spring from being exposed and has a good appearance.

For this reason, the connecting pin 13 is loosely fitted in the through holes 27 and 28.

  Further, a spring member 14 is rotatably supported by the connecting pin 13. As shown in FIG. 4, the spring member 14 is formed by extending both end portions 36 and 37 straightly from a coil portion 35 obtained by winding a metal bar in a coil shape. The coil part 35 is formed to have an inner diameter larger than the outer diameter of the connecting pin 13, and the connecting pin 13 is loosely fitted to the coil part 35. Both end portions 36 and 37 extend in the tangential direction of the coil portion 35 and are formed in a V shape.

  On the other hand, the other end portions of the ring pieces 11 and 12 are formed to be engageable with each other as shown in FIG. A projection 38 having a rectangular cross section extending in the circumferential direction along the inner peripheral surface is provided at the other end of the ring piece 11, and a projection 35 is engaged with the other end of the ring piece 12. A mating recess 39 is provided.

  Next, an example of the assembly procedure of the ring 10 of the present embodiment will be described.

  First, the ring piece 12 is fixed by chucking with a jig or the like. Then, the spring member 14 is assembled between the protrusions 25 and 26 of the ring element 12. As shown in FIG. 2, the spring member 14 is arranged such that the coil portion 35 is positioned between the through holes 27 and 28 with both end portions 36 and 37 facing the inside of the ring. At this time, one end of the spring member 14 is accommodated in the second space 34 and the other protrudes from between the protrusions 25 and 26 (hereinafter, the end 36 is the second space). 34).

  Subsequently, one end portions of the ring pieces 11 and 12 are brought close to each other, the projecting portions 25 and 26 are inserted between the support portions 16 and 17, and the end portion 37 of the spring member 14 is inserted into the first space portion 21. Then, the support portions 16 and 17 are disposed so as to face the arcuate wall surface 40 standing along the step surfaces 31 and 32. At this time, the through holes 18 and 19 and the through holes 27 and 28 are arranged substantially coaxially.

  Next, the connecting pin 13 is inserted into the through hole 19, and the through hole 28, the spring member 14 (coil portion 35), the through hole 27, and the through hole 18 are passed through in this order. Thereby, the one end part of the ring piece 12 is rotatably supported by the connection pin 13 fixed to the one end part of the ring piece 11, and the ring pieces 11 and 12 are mutually connected. Further, since the connecting pin 13 is passed through the coil portion 35, the spring member 15 is supported by the connecting pin 13, and both end portions 36 and 37 are inner walls of the second space portion 34 and the first space portion 21, respectively. It will be in a state of being pushed and spread.

  Note that both ends of the connecting pin 13 are joined to the inner peripheral surfaces of the through holes 18 and 19 by laser welding, brazing or the like, thereby increasing the fixing force of the connecting pin 13 and the boundary with the through holes 18 and 19. Can be made inconspicuous.

  Next, operation | movement of the ring 10 of a present Example is demonstrated.

  FIG. 5 is a cross-sectional view before the other end portions of the ring pieces 11 and 12 are engaged (when the ring is opened), and FIG. 6 is a cross-sectional view after the other end portions are engaged (when the ring is closed). is there. As shown in FIG. 5, when the one end portions of the ring pieces 11 and 12 are connected by the connecting pin 13, the first space portion 21 and the second space portion 34 are communicated with each other, and the arc-shaped space portion S is connected. Is formed.

  The spring member 14 is supported by the connecting pin 13 in the space S, and ends with the inner wall of the space S at a position sandwiching the connecting pin 13, that is, the inner wall 41 on the inner peripheral side of the second space 34. The portion 36 presses, and the end portion 37 presses the inner wall 42 on the inner peripheral side of the first space portion 21. Thereby, the spring member 14 urges the ring pieces 11 and 12 in the direction in which the ring is closed (the direction in which the other ends approach each other) with the connecting pin 13 as a fulcrum.

  As shown in FIG. 6, the ring pieces 11, 12 are biased by the spring member 14, so that the protrusions 38 and the recesses 39 are naturally engaged and are closed. Even in a state where the other end portions are engaged with each other, the spring member 13 continues to urge the ring pieces 11 and 12. Thereby, the closed state of the ring 10 is maintained.

  Further, as shown in FIG. 5, the tip portions 29 and 30 accommodated in the first space portion 21 are not in contact with the inner wall of the first space portion 21 when the ring pieces 11 and 12 are opened. However, as shown in FIG. 6, it contacts the inner wall 43 on the outer peripheral side when the ring is closed. On the other hand, when the ring pieces 11 and 12 are turned away from the state of FIG. 5, the tip portions 29 and 30 abut against the inner wall 42 on the inner peripheral side of the first space portion 21.

  Thus, the tip portions 29 and 30 move in the first space portion 21 as the ring pieces 11 and 12 rotate, and come into contact with any of the inner walls 42 and 43 when the predetermined rotation angle is reached. . For this reason, since the rotation range of the ring pieces 11 and 12 is limited by the tip portions 29 and 30, it is possible to bring a sense of stability to the operation, and furthermore, due to excessive rotation of the ring pieces 11 and 12. Damage or the like can be prevented.

  In particular, in this embodiment, as shown in FIG. 6, the tip portions 29 and 30 are brought into contact with the inner wall 43 of the first space portion 21 at the timing when the other end portions of the ring pieces 11 and 12 are engaged with each other. Therefore, the other end portions can be easily aligned. In addition, since the contact between the other end portions can be relaxed, damage to the ring pieces 11 and 12 can be prevented.

  In the present embodiment, since the spring member 13 is not exposed to the outside in a state where it is accommodated in the space S, the appearance of the ring 10 can be improved. Moreover, since the support parts 16 and 17 are arrange | positioned so that rotation is possible along the wall surface 40 of the level | step difference surfaces 31 and 32, respectively, the dent of the level | step difference surfaces 31 and 32 can be eliminated. For this reason, the aesthetic appearance of the ring 10 is not impaired.

  In this embodiment, the spring member 14 is rotatably supported by the connecting pin 13 disposed between the first space portion 21 and the second space portion 34. For this reason, the spring member 13 can be held at a predetermined position in the space S in a predetermined posture regardless of the rotation of the ring pieces 11 and 12, and the spring member 14 can be prevented from being displaced and the predetermined spring can be prevented. Force can be generated continuously. Moreover, an assembly property can be improved by letting a connection pin pass through the coil part of a spring member.

  The ring 10 of the present embodiment can be easily attached and detached because the inner diameter of the ring can be increased simply by pulling at least one of the ring pieces 11 and 12 outward while being attached to the finger. Can be done.

  In addition, the ring 10 of a present Example can attach ornaments, such as a jewel, in the vicinity of the connection part of other end parts, or along an outer peripheral surface in the outer peripheral surface of the ring piece 11,12, for example. In particular, by attaching an ornament in the vicinity of the connecting portion, the dividing surface becomes inconspicuous and the appearance can be improved.

  FIG. 7 is an enlarged view showing the connection structure of the ring pieces 11 and 12 according to the second embodiment. This embodiment is different from the first embodiment in that a leaf spring 50 is used in place of the spring member 14 of the first embodiment, and the other configuration is the same as that of the first embodiment.
