Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a connecting fitting for jewelry such as a necklace, a pendant, and a bracelet.

[Prior art] Conventionally, as connecting metal fittings for necklaces, pendants, bracelets, and other accessories, (a)
Providing a protrusion or a hole in the center of a leaf spring as described in -103624, 1982-130712, 150910/1982, and 169112/1999, Some had protrusions or holes in the corresponding positions of the cylindrical receiving fittings so that they could be fitted into the fittings.

In addition to the above, (b) necks are provided on both sides of the leaf spring as described in Japanese Utility Model Application Publication No. 57-189413 and Japanese Utility Model Application Publication No. 1-141618. There was one in which protrusions were formed on both ends to fit into the neck portion provided on the leaf spring.

The above-mentioned connecting fittings for jewelry are superior to the previous ones, which had a partially open ring-shaped fitting with a retractable pin built in, and the pin was operated by a lever, in that it could be attached and detached with a single touch. It is.

[Problems to be solved by the invention] However, in the above-mentioned connecting fittings for jewelry, group (a) requires the thickness of the cylindrical receiving fitting to correspond to the height of the protrusion, making the whole compact. The drawback was that it was difficult to

In addition, in group (b), necks are provided on both sides of the leaf spring, and protrusions are formed at both ends of the opening of the cylindrical receiving metal fitting, which are approximated in that they fit into the necks provided on the leaf spring. However, the operating lever provided on the leaf spring protruded outward from the cylindrical receiving metal fitting, spoiling its appearance.

Therefore, this idea solved the above-mentioned problems of the conventional example, and not only made the cylindrical metal holder thinner, but also made it possible to prevent the operating lever provided on the leaf spring from protruding outside of the cylindrical metal holder. The purpose is to provide a connecting fitting.

[Means for Solving the Problems] In other words, the accessory connecting fitting of this invention is an accessory comprising a cylindrical receiving fitting attached to one end of the accessory and a V-shaped leaf spring attached to the other end of the accessory. In the connecting fitting, a cylindrical receiving fitting is built into the one end of the accessory, one of both ends of a V-shaped leaf spring is fixed to the other end of the accessory, and the V-shaped plate spring is fixed to the other end of the accessory.
By making the other end of the letter a free end and providing protrusions and fitting grooves on the opening of the cylindrical holder and the fixed end of the V-shaped plate spring, the V-shaped plate spring can be attached to the cylindrical holder. When stored, the protrusion is prevented from coming off by engagement with the fitting groove, and the elasticity of the leaf spring can be used to release the engagement between the protrusion and the fitting groove and remove the protrusion. It is something to do.

[Function] Since the connecting fitting for jewelry of this invention is constructed as described above, it is possible to make the cylindrical receiving fitting thinner, and there is no need to provide an operating lever on the leaf spring. Since it does not protrude outward from the receiving metal fitting, the appearance of the accessory can be greatly improved.

Further, the leaf spring can be held at a predetermined position within the cylindrical receiving metal fitting, and can be easily attached and detached in substantially the same manner as before.

[Example] Hereinafter, an example of the connecting metal fitting for jewelry of this invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 designates a cylindrical receiving fitting built into one end of an accessory 21 used to connect the ends of a necklace, pendant, bracelet, or other item. On both sides of the upper part of the opening 3 of this cylindrical receiving fitting 1, projections 5 are provided to protrude toward the inside of the cylindrical shape. 13 is a slit formed on the bottom surface.

Further, a V-shaped plate spring 7 is provided protruding from the other end of the accessory 21. That is, as shown in FIGS. 1 and 3, one of both ends of the V-shape of the leaf spring 7 is fixed to the other end of the accessory 21, and the other end is a free end. A fitting groove 11 is provided on the fixed end 9 side of the leaf spring 7 at a position close to the accessory 21. In the figure, this fitting groove 11 is a notch.
When processing the leaf spring 7, it is desirable to fix it to the other end of the accessory 21 by brazing or the like and then process it into a V-shape so that it does not become dull due to the heat generated during heating.

When using this device, the V-shaped leaf spring 7
When the is housed in the cylindrical holder 1, the protrusion 5
It is prevented from coming off by engagement with the fitting groove 11. In addition, the fixed end 9 of the leaf spring 7 along with the other end of the accessory 21
By pushing in the thickness direction of the plate spring 7, the engagement between the protrusion 5 and the fitting groove 11 can be disengaged using the elasticity of the plate spring 7, and the engagement between the protrusion 5 and the fitting groove 11 can be released, and the protrusion 5 can be easily removed.

[Effects of the invention] Since the connecting fitting for jewelry of this invention is constructed as described above, it is possible to make the cylindrical receiving fitting thinner, and there is no need to provide an operating lever on the leaf spring. Since it does not protrude outward from the shaped receiver, the appearance of the accessory can be greatly improved.

Further, the leaf spring can be held at a predetermined position within the cylindrical receiving metal fitting, and can be easily attached and detached in substantially the same manner as before.
