Abstract

PURPOSE:To dispense with independent joint metal fittings to be called a clasp by jointing the elements of necklaces or the like for using the repulsion of magnetism with a magnet, to each other. CONSTITUTION:A male form 2 is fitted so that the same poles of a magnet 6 may come to a tip, and a female form 1 is fitted so that the same poles of the magnet 6 may come to a bottom. The male form 2 consists of a thin round-column-shaped section to be inserted into the female form 1, and a thick root section, and near the tip of the thin section, the stopper 4 of a small projection is fitted. The female form 1 is formed in the shape of the round column of the same thickness with a hole-board section for the male form 2 to be inserted into a root section with the magnet 6 contained in, and in the hole of the female form 1, a vertical channel 8 for the stopper 4 of the male form 2 to be inserted into, a horizontal channel for the stopper 4 to slide horizontally from a point for the female form 1 in contact with the bottom of the hole, into, a small vertical channel and a key-type channel for the male form 2 and the female form 3 to be repulsed to each other and to be returned by a magnetic force, are formed. When the male form 2 is pushed into the female form 1 and is stopped at a time point when the horizontally torsional male form 2 is slightly returned, then joint metal fittings not to be returned by a magnetic force are formed.

Description

Detailed Description of the Invention

The connecting metal fittings are made of cylindrical male and female types. The male type is equipped with magnets at the tip part and the female type is fitted at the bottom part so that the S poles or the N poles come respectively.

The male type consists of a thin cylindrical part that fits into the female type and a thicker root part, and a small protrusion that acts as a stopper is attached near the tip of the thin part.

The female mold has a cylindrical shape with the same thickness in the hole where the male mold is inserted and the base part where the magnet is contained, and a male stopper can be inserted in the female mold hole. A vertical groove,
A horizontal groove that allows the stopper to slide sideways from the point where the male and female molds make contact at the bottom of the hole, and a small vertical groove that allows the male and female molds to repel by magnetic force and return. , With a key-shaped groove carved.

By this mechanism, the male mold is pushed to the female mold,
If you stop it when the twisted male type returns a little to the side, it will be a connection fitting that will not return due to magnetic force.

This connecting fitting can be as small as 2.5MM in minimum diameter and 15MM in length.

The main body of the connecting fitting can be incorporated into a material such as a necklace (for example, a pearl of a real pearl).

By incorporating the main body of the connecting fitting into a material such as a necklace, it looks like a necklace or the like made of only the material without the connecting fitting.

[0008] A necklace or the like with connection fittings becomes an endless article without joints.

[Industrial applications]

Jewelry precious metal industry

Accessory industry

[0011] Clothing industry

[Prior Art]

All of the connecting fittings using magnets utilize the attractive force of the magnetic force.

Leaf spring type made of metal

Middle stop type

Hook type

Pull ring tube type

Screw type

A metal other than a material such as a necklace is used.

Irrespective of the image of a material such as a necklace, an item having a design as an independent connecting metal fitting was used.

There are many failures due to wear of metal.

There are many failures due to defective springs.

In addition to the original function as a connecting fitting, a variation in design was required.

It takes a lot of time and effort to attach and detach.

[Problems to be Solved by the Invention]

[0024] Connection hardware with few failures

[0025] Connecting fittings for showing on necklaces made only of materials (endless necklaces).

A connection fitting that is small and easy to attach and detach.

[Means for Solving the Problems]

The magnetic force of a magnet is
We will make connection fittings that use semi-permanent holding.

By using the magnetic metal fitting, a fitting that is durable and can be used for a long time is used.

Since it has a simple structure, it can be easily attached and detached.

By miniaturizing the connecting fitting, the fitting main body is incorporated into the material of the necklace or the like.

By connecting materials such as a necklace, it is not necessary to insert a connecting fitting of another independent design.

[Action]

This pearl necklace always had an independent connecting fitting called a clasp made of silver or gold, but by using this new connecting fitting, an endless necklace with only pearls can be made.

【Example】

[0033] Connection fittings for this pearl necklace.

【The invention's effect】

An endless necklace is created.

Jewels Brings new product lines to precious metals, especially the pearl industry.

The value of the necklace changes.

Common sense about necklaces changes.

The aesthetic sense of the necklace changes.

Awareness of the connection fittings changes.

The pearl necklace has a simple and best shape.

[Brief description of drawings]

FIG. 1 is a plan view showing a connection fitting built into a pearl necklace. (As an example, the figure shows pearls, but the material is not limited to pearls, and it is possible to use only connection fittings that are not built in.)

FIG. 2 is a cross-sectional view showing a connection fitting built into a pearl necklace.

[Explanation of symbols]

 1. The top view of the female type of a connection metal fitting. 2. The top view of the male type of a connection metal fitting. 3. The pearl at the connecting part of a pearl necklace. 4. A stopper attached to the male mold. 5. A ring tube to hold the thread that connects the pearl necklace. 6. A magnet installed inside the connection fitting. 7. The same poles of the magnets. 8. A groove that functions as a stopper as a connection fitting.

Claims (2)

[Claims] 1. A connection fitting such as a necklace or bracelet that utilizes the magnetic repulsive force of a magnet. 2. A connecting fitting that can be incorporated in a material such as a necklace or a bracelet (pearl etc.).
