Technical field

The present invention relates to a ring, and more particularly, to a ring that can be changed in size and that can be attached to the ring and that can be used to freely exchange ornaments such as jewels and pearls.

Background art

[0002] In general, a ring is set in a plurality of sizes with different diameters of a ring portion attached to the finger. When purchasing a ring, if the size of the desired ring is too strong to fit your finger, you will have to give up purchasing that ring or adjust the size to fit your finger. In addition to the cost of the ring, there was a lot of processing cost.

Also, on the retailer side, even if a ring has the same design, the ring often holds a plurality of types of sizes, and there is a possibility that the ring that is held may become surplus inventory. For this reason, dealers sometimes pass on the risk of excess inventory to rings, causing the prices of rings to soar.

In order to solve the above problems, Patent Literature 1 and Patent Literature 2 disclose rings that are capable of resizing the ring by the purchaser themselves.

The ring described in Patent Document 1 is a ring formed by disposing a panel inside a ring-shaped support member and connecting ball chains to both ends of the panel to form a ring. Thus, if a ring is attached to a finger, the panel can be stretched according to the thickness of the finger to ensure a secure fit.

The ring described in Patent Document 2 can arbitrarily set the inner peripheral length by wrapping the free ends of each other and adjusting the wrap length of the ring-shaped panel member with the stove member. is there.

Disclosure of the invention

[0003] By the way, the ring described in Patent Document 1 has the same appearance as a normal ring on the decorative body side. However, if the ball chain is exposed on the palm side, the appearance of the ball chain is not good, or if the panel is stretched out of the elastic range, it will not be restored. There is a problem that it cannot be mounted properly.

Further, the ring described in Patent Document 2 is provided with a stove that regulates the ring size in the ring portion, and is attached to the decorative body canning portion such as a diamond or a pearl so that the ring is V-shaped. Lack of beauty poses a challenge.

In addition, the rings described in Patent Documents 1 and 2 both have a problem that the wearing feeling is different from that of the tubular ring, causing a sense of incongruity, and that only the decorative body cannot be replaced. . Therefore, the present invention provides a ring that can be easily changed in size and that can be replaced only with a decorative body, while having the same appearance and wearing feeling as a normal ring. It is an object.

According to the present invention, the metal strip is formed in a ring shape so that one end side and the other end side overlap with each other, and the both ends are provided so as to be relatively movable in the circumferential direction, so that the diameter is increased. A ring portion provided so as to be able to reduce the diameter, and a pedestal portion detachably provided on the ring portion so as to cover the overlapping portion on both ends of the ring portion. It is.

Further, a locking portion is provided between the one end side and the other end side to lock at a plurality of required movement positions. This eliminates the risk that the ring will fall off even when the finger is worn while the size of the ring once set does not change.

Further, the one end side and the other end side overlap in the width direction.

Further, the one end side and the other end side overlap in a thickness direction.

As a result, it is possible to select the form of diameter expansion and contraction of the ring portion suitable for the design of the ring, and the degree of freedom in the design of the ring is greatly improved.

Further, the pedestal portion, from the base plate covering the outer surface side of the overlapped portion, from both edges of the base plate And a bent piece that extends to the inner surface side of the overlapping portion and is bent in a direction facing each other to sandwich the overlapping portion between the base plate and the base plate.

Further, a narrow portion narrower than the overlapping portion is provided in a portion other than the overlapping portion of the ring portion, so that the pedestal portion enters the gap between the two bent pieces so that the narrow portion enters. The overlapping portion is sandwiched between the base plate and the bent piece by being applied to the ring portion and sliding in the direction of the overlapping portion.

As a result, the superposed state of the superposed portion can be hidden by the pedestal portion, so that there is no difference in appearance from ordinary rings.

Further, the bent piece is formed so as to be fittable in the narrow portion, and the pedestal portion is formed detachably with respect to the ring portion only at the position of the narrow portion. I do.

Further, an engaging portion for fixing the pedestal portion is provided between the bent piece and the overlapping portion.

Further, the engaging portion is provided with a notch provided on at least one of the bent pieces and on the inner wall surface side of the overlapped portion, and has a force acting on the notch entering the notch. It is characterized by the following.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of a ring according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of a ring 10. As shown in FIG. 1, FIG. 2, and FIG. 3, the ring 10 is formed in a ring shape such that one end side 20 and the other end side 22 of a strip made of metal overlap with each other. Since both ends 20 and 22 are provided so as to be relatively movable in the circumferential direction, a ring portion 24 (FIG. 2) provided so that the diameter can be increased or reduced, and an overlap between both ends 20 and 22 of the ring portion 24. A pedestal portion 28 detachably provided on the ring portion 24 so as to cover the portion 26; An appropriate decorative portion 29 such as a jewel is attached to the pedestal portion 28.

The ring portion 24 in this embodiment is made of a noble metal such as silver, gold, platinum, or an alloy thereof. Formed Force The ring portion 24 may be formed of another metal such as stainless steel or titanium.

As shown in FIG. 2, the ring portion 24 has both ends 20 and 22 overlapping in the width direction, and a locking portion 30 which also has an uneven force is provided on the opposing surfaces of the both ends 20 and 22. ing. This locking part 30 is provided with one locking claw 31 provided on one end side 20 and a saw-shaped locking claw provided on the other end side 22 and locked by the locking claw 31. Consists of 32. Therefore, by moving the both ends 20, 22 relatively in the circumferential direction to lock the locking claw 31 at a required position of the locking claw 32, the diameter of the ring portion 24 can be increased and reduced ( Ring diameter). Although not shown, a symbol or a number indicating the size of the ring 10 may be displayed near the locking claw 32.

A plurality of locking claws 31 may be provided.

The shape of the locking claws 31, 32 may be a wave shape, and is not particularly limited. In the ring portion 24, a narrow portion 34 having a width W2 smaller than the width W1 of the overlap portion 26 is formed in a portion other than the overlap portion 26.

In addition, a stopper (engaging portion) 36 is formed on the inner surface of the overlapping portion 26. The stop 36 will be described later.

The pedestal part 28 has an arc shape whose shape when viewed from the side substantially follows the arc of the ring part 24.

As shown in FIGS. 3 and 4, the pedestal portion 28 has a base plate 38 that covers the outer wall surface side of the overlapped portion 26, and a force that opposes both edges of the base plate 38 to the inner surface side of the overlapped portion 26. And bent pieces 40a and 40b sandwiching the overlapped portion with the base plate 38.

An interval W3 (FIG. 4) between the two bent pieces 40a and 40b is set to be substantially the same as or slightly larger than the width W1 of the overlapping portion 26.

The distance W4 (FIG. 4) between the bent pieces 40a and 40b and the base plate 38 is provided so as to be substantially equal to the thickness of the overlapping portion 26.

The width W5 (FIG. 3) of the gap between the distal ends of both bent pieces 40a and 40b is set to be equal to or greater than the width W2 of the narrow portion 34 of the ring portion 24!

The pedestal portion 28 is mounted so as to abut the narrow portion 34 of the ring portion 24 from the outside. You That is, the pedestal portion 28 is applied to the ring portion 24 such that the narrow portion 34 enters the gap between the two bent pieces 40a and 40b. The pedestal portion 28 is attached to the ring portion 24 by being slid in the direction of the overlapping portion 26 so that the overlapping portion 26 is sandwiched between the base plate 38 and the two bent pieces 40a and 40b from the front and back. is there.

At this time, the pedestal portion 28 completely covers the outside of the overlapping portion 26. Therefore, the appearance of the ring 10 that prevents the overlapping portion 26 from being seen from the outside is not spoiled.

Further, since the width, Wl, W3, W4, and the like are set to the above dimensions, the pedestal portion 28 is densely mounted on the overlapping portion 26.

Note that the cross-sectional shapes of the ring portion 24 and the pedestal portion 28 in the width direction are not limited to the above.It is important that when the pedestal portion 28 is slid on the overlap portion 26, the pedestal plate 38 and the two bent pieces 40a, It is sufficient that the cross-sectional shape is such that the overlapping portion 26 is sandwiched between 40b and 40b. For example, the cross-sectional shape of the ring portion 24 may be a flat ellipse or the like, and the pedestal portion 28 may have an inner surface shape corresponding thereto.

Next, the structure of the stopper 36 will be described with reference to FIGS.

The stopper 36 is for fixing the pedestal portion 28 at a position where the pedestal portion 28 is mounted on the overlapping portion 26.

The stopper 36 is incorporated on the inner wall surface side of the one end portion 20 and rotates about the shaft 42, has a claw piece 43 on one side, and is opposite to the claw piece 43 across the shaft 42. There is a protrusion 44 on the side (Fig. 8).

FIG. 7 shows an assembled structure of the stopper 36. On the inner wall surface on one end side 20 of the ring portion 24, a concave portion 45 capable of housing the shaft 42 of the stopper 36 and the projecting piece 44 is formed. After the shaft 42 and the projecting piece 44 are housed in the recess 45, plate members 47, 47 for covering the shaft 42 and partially closing the recess 45 are attached to the inner wall surface on one end side 20. Fix it. As another method of closing a part of the concave portion 45 for covering the shaft 42, a method of drawing the ring portion 24 or the like can be adopted.

As a result, the stopper 36 is prevented from falling out of the concave portion 45, and is rotatable about the shaft 42 in a plane perpendicular to the length direction of the ring portion 24.

In FIG. 8, reference numeral 48 denotes an elastic member (biasing member) which also has a force such as silicone rubber, and is provided inside the recess 45. In FIG. 8, the protrusion 44 is elastically pressed in the counterclockwise hand rotation direction. As a result, the claw piece 43 is pressed toward the inner wall surface on the one end side 20.

The elastic member 48 can be disposed so as to be forcibly pushed into the concave portion 45 from a hole 49 opened on the bottom surface of the concave portion 45.

Alternatively, after storing the elastic member 48 in the recess 45 in advance, the stopper 36 may be assembled to the recess 45 as described above.

On the other hand, as shown in FIG. 3, one bent piece 40a of the pedestal portion 28 is provided with a notch 41 into which a claw piece 43 can enter.

Accordingly, as described above, when the pedestal portion 28 is applied to the ring portion 24 and the slide portion is slid in the direction of the overlap portion 26, the end surface force of one bent piece 40a reaches the position where it comes into contact with the end surface of the stop bar 36. Then, lift the claw piece 43 against the urging force of the elastic member 48 with a finger or the like, and lift the claw piece 43 on the bent piece 48a (the state is shown in FIGS. 5 and 9). When the pedestal portion 28 is slid, the claw piece 43 reaches the notch 41, and the claw piece 43 is rotated by the urging force of the elastic member 48, and is brought into the notch 41 (see FIG. Shown). As a result, the pedestal portion 28 is fixed at a position covering the overlapping portion 26. When the pedestal portion 28 is to be removed, the pedestal portion 28 can be slid by lifting the claw piece 43, and thereby can be removed.

As described above, the diameter of the ring portion 24 can be freely adjusted. Further, since the pedestal portion 28 can be removed from the ring portion 24, various jewels can be enjoyed by replacing the pedestal portion 28.

The structure of the engaging portion for fixing the pedestal portion 28 at the position covering the overlapping portion 26 is not limited to the above stove mechanism. For example, instead of the stopper 36, a hemispherical small protrusion (not shown) may be provided on the inner wall of the one end 20 of the ring portion 24, and this small protrusion may fit into the notch 41. Therefore, in this case, the width of the notch 41 is narrow enough to fit the small projection. Alternatively, in this case, instead of the notch 41, a small concave portion (not shown) may be provided on the inner surface side of the bent piece 40a, and the small protrusion may be fitted into the small concave portion. The small protrusion may be provided on the inner wall surface side of the bent piece 40a, and the small concave portion may be provided on one end 20 side. The positions where these small projections and small recesses are provided on the bent piece 40a and on one end side 20 are particularly limited. It is not specified. The point is that when the pedestal portion 28 is slid over the overlapping portion 26, it should be in a position where they are engaged.

The small projections are formed in a ball shape, and are provided in the bent piece 40a or in a hole (not shown) provided on one end side so as to partially protrude the external surface force. A well-known mechanism in which the ball protrudes into the hole by being sexually received by the spring is adopted.

As described above, the ring has been described in detail based on the embodiment. However, the ring according to the present invention is not limited to the embodiment described above, and various changes may be made without departing from the gist of the invention. Needless to say, even if it does, it belongs to the technical scope of the present invention. Hereinafter, another embodiment of a ring that is useful for the present invention will be described.

FIG. 10 shows another embodiment.

In the present embodiment, one end 20 of the ring portion 24 and the other end 22 are arranged to overlap in the thickness direction. Other configurations are the same as those of the above embodiment. Also in the present embodiment, when the pedestal portion 28 is slid to a position covering the overlapping portion 26, an engaging portion (not shown) for fixing the both may be provided.

FIG. 11 shows still another embodiment.

In the present embodiment, a concave groove 50 that is open at both ends is provided on the inner wall of the bent pieces 40a and 40b that do not bend the bent pieces 40a and 40b inward, and one end of the ring portion 24 is provided. Protrusions 51 that fit into the concave grooves 50 are provided at 20 and the other end 22 so that the pedestal 28 can slide on the ring 24.

The ridge 51 is provided, for example, only in the overlapping portion 26, so that the pedestal portion 28 is applied to the ring portion 24 at a portion where the ridge 51 is not provided, and the pedestal portion 28 is slid in the direction of the overlapping portion 26, and The pedestal portion 28 can be mounted on the overlapping portion 26 by engaging the ridge 51 with the concave groove 50. In this embodiment, too, the small projection and the small projection for fixing the pedestal portion 28 and the ring portion 24 are provided. It is preferable to provide an appropriate engaging portion (not shown) such as a concave portion.

FIG. 12 shows still another embodiment. The curvature R1 of the arc portion 38g formed by the base plate 38 of the pedestal portion 28 is calculated from the curvature R2 of the arc portion 40η formed by the opposite end of the bent piece 40a. It is preferable to make the diameter smaller. Thereby, the clearance D at the central portion of the pedestal portion 28 can be made larger than the clearance at the both end portions of the pedestal portion 28. Therefore, even if the size of the ring 10 is set to the minimum size or the maximum size, even if the ring 20 is misaligned, the end portions 20 and 22 of the ring portion 24 and the pedestal portion 28 come into contact with each other. Since the occurrence of abrasion can be prevented, it is possible to use the ring 10 for a long period of time while maintaining the condition of the ring 10.

Industrial applicability

In the present invention, a ring has been described as a specific example of an ornament, but the present invention can of course be applied to other ornaments used by adjusting the length in the same manner as the ring. Specifically, if the present invention is applied to a bracelet, anklet, belt buckle, watch, etc., the length can be easily adjusted, and the decorative body can be exchanged freely. It becomes possible to enjoy various ornaments.
