Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a chain link for accessories such as pendants, necklaces, bracelets, etc., in which both ends of the chain are connected and the chain is hung around the neck. .

Conventional techniques and problems Conventionally, various types of connectors for jewelry chains have been provided, such as plug-in type, pull ring type, and snap type, but these are easy to attach and detach. Items come off easily and are often lost when going out carelessly, and items that are made to be difficult to remove tend to have a complicated structure, making it troublesome for the user to put on and take off. It was cumbersome to connect them at the back of the neck with pendants and the like.

Purpose of the present invention Therefore, the present invention was devised in view of the above-mentioned conventional problems. To provide a chain connector for jewelry, which can surely prevent the inconvenience of accidental detachment and loss, and which can be easily attached and detached at the chest position when used as a pendant.

Means for Solving the Problems Therefore, the present invention provides a linking device for a chain for jewelry such as a pendant, a necklace, or a bracelet, in which the connecting device has a first ring attached to one end of the chain, and a second ring attached to the other end of the chain. A narrow notch through which the second ring cannot pass is provided in a part of the first ring, and a concave groove corresponding to the notch is provided in the inner and outer directions in a part of the second ring. , only when the first ring is relatively moved in a direction orthogonal to the inner and outer directions of the second ring with the notch and groove aligned, the groove passes through the notch and the first ring and second ring are separated. In addition, at a position near the groove, the side surface of the groove can be slid in the inner and outer directions of the second ring with the first ring orthogonal to the second ring. A U-shaped handle with a chain stopper hole formed in the guide part is fixed, and the side surface on the side of the handle serves as a guide for positioning the notch and the groove when attaching and removing the ring. This is an attempt to solve the above problems.

Effect With the above configuration, in order to connect the chains using the connecting tool, the first ring should be moved in the inner and outer directions of the second ring with the concave groove of the second ring aligned with the notch of the first ring. When the first ring and the second ring are moved relative to each other in orthogonal directions, the first ring and the second ring are engaged in a connected state. At this time, hold the first ring with one hand, hold the handle of the second ring with the other hand, and align the notch of the first ring along the side of the handle in the direction from the tip of the handle to the proximal end. By sliding the handle, the handle acts as a guide for positioning, and the notch and groove can be easily positioned and fitted, so they can be connected with one touch. Removing the chain is equally easy, and once engaged, the rings will not come apart unexpectedly, even if a large tension ring is applied to the coupling.

Embodiment Hereinafter, the configuration of the present invention will be explained with reference to an embodiment shown in the drawings.

Reference numeral a is a connector for connecting both ends of chain b for accessories such as pendants, necklaces, bracelets, etc., and this connector a is composed of a second ring 12 attached to one end of chain b. Each of these rings 11 and 12 may have a rectangular, circular, or elliptical cross-sectional shape, and the shape of the ring is not necessarily limited to circular. For example, a deformed ring such as a heart shape may be used.

Furthermore, it is also possible to use one or both of the first ring 11 and the second ring 12 as the pendant body. In that case, it is also possible to process the desired design on the side of the ring, which becomes the main body of the pendant, or to incorporate a separate member for decoration inside the ring.

Figures 3 and 4 show a decorative body c in which a jewel J such as a diamond is set in a first ring 11 formed in a heart shape.
The first ring 11 itself is formed into a pendant body by hanging the ring 11 in a loosely fitted manner.

Now, a notch 13 for engaging and disengaging the second ring 12 is formed in a part of the first ring 11. The mutually opposing notch ends forming the notch portion 13 are formed in a mountain shape as shown in FIG. w is the second ring 12
The width is set so that it cannot pass through.

Note that although the notch end portion is formed in a substantially semicircular shape in the illustrated example, it may be formed in a trapezoidal or triangular shape, or the notch end surface may simply be a flat surface. Further, the mountain-shaped portions 13a may be provided on both of the notches 13 facing each other as shown in the figure, or may be provided only on one side. Reference numeral 14 designates a mounting ring for chain b that is loosely fitted to the first ring 11.

Incidentally, on the upper and lower surfaces of the second ring 12, grooves 15 are formed in the inner and outer directions, corresponding to the notches 13 provided in the first ring 11, and matching with the mountain-shaped portions 13. In a position near the groove 15, the side surface 16b of the groove 15 is formed into a guide portion that can slide in the inner and outer directions of the second ring 12 with the first ring 11 orthogonal to the second ring 12. U-shaped handle 16 with formed chain stopper hole 16a
is integrally fixed to the ring 12, and the handle 16
The side surface 16b on either side of the groove 15 serves as a guide for positioning the notch 13 and the groove 15 when the rings 11, 12 are attached or removed.

Now, in order to connect chain b using connector a, connect groove 15 of second ring 12 to first ring 1.
The first ring 1 is aligned with the notch 13 of the first ring 1.
1 in a direction orthogonal to the inner and outer directions of the second ring 12, the first ring 11 and the second ring
Ring 12 is engaged in a connected state. At this time, hold the first ring with one hand, hold the handle 16 of the second ring with the other hand, and hold the notch 13 of the first ring.
By sliding the handle 16 along the side surface 16b of the groove 15 from the distal end side of the handle 16 toward the proximal end, the handle 16 performs a guiding action and moves the chevron-shaped portion 13a of the notch 13 against the groove 15. Since the fitted state can be easily positioned, the first ring and the second ring 12 can be connected with one touch without having to align the grooves while checking the first ring and the second ring 12 at a glance.

Further, once both rings 11 and 12 are connected, the mountain-shaped portion 13a and the groove 15 are connected as described above.
rings 11 and 12 unless you intentionally fit them together.
will not come off unexpectedly. That is, in the present invention, as shown in FIG.
Only when the second ring 12 is relatively moved in a direction perpendicular to the inner and outer directions of the first ring 11 with the groove 15 inserted into the groove, the groove 15 passes through the notch 13 and the first ring 11 and the second ring 12 are configured to be able to be engaged and disengaged, even if the rings 11 and 12 of the connector a are pulled together at the position where the notch 13 and the groove 15 are joined. However, the groove 15 cannot pass through the notch 13, and the rings 11 and 12 will not come apart in the direction of tension. Also, even if chain b
Even if a large tensile force is applied to the connector a through the chain b, the rings 11, 1
Since the pulling direction of 2 and the direction of removing rings 11 and 12 are at completely different angles, the rings will not come off.

When removing the rings 11 and 12, use the chevron-shaped part 13a.
After positioning the concave groove 15, the rings 11,1
2 in the opposite direction to the above, it can be easily removed in the same way as above.

Effects of the Invention Since the present invention is configured as described above, it is extremely easy to chain an accessory by simply aligning the groove with the notch and slightly moving the first ring relative to the groove of the second ring. In addition to being able to attach and detach the ring securely, the handle not only serves as a grip when attaching and detaching the ring, but also serves as a guide for positioning the notch and groove, allowing you to check the notch and groove at a glance. Positioning and fitting can be performed with a single touch without any hassle, making it possible to perform the attachment/detachment operation more quickly and smoothly. In addition, once the rings are connected, even if the rings of the connector are pulled together at the position where the notch portion and the groove portion are joined, the groove cannot pass through the notch portion. Furthermore, even if a large tensile force is applied to the connector via the chain, the direction in which the chain pulls the ring and the direction in which the ring is removed are at completely different angles, so the rings will not come apart and the notch will Since it will not come off unless you consciously match the part and groove to the fitted state, it is possible to reliably prevent the chain from accidentally coming off and being lost during gluing, and the ring can also be used as the pendant body. Moreover, it has extremely useful practical effects such as being able to simplify the structure and provide it at low cost.
