Description

[Detailed description of the invention] [Industrial application field] This invention enables secure attachment and detachment of a pair of connectors by simply applying pressure in the axial direction, such as necklaces and bracelets. This invention relates to a fastener for jewelry used in jewelry.

[Prior Art] As for fasteners for jewelry, those having various shapes and mechanisms have been devised and used in the past.

[Problem that the invention attempts to solve]

However, in general, clasps for jewelry are very small and have a fine structure, but they must support a large amount of weight such as precious metals. It hardly existed.

[Means to solve the problem]

Therefore, this invention was developed with the aim of providing a fastener for jewelry that can be reliably attached, held, removed, etc. with simple operations by comprising the following pair of connectors. This is what I did.

In other words, this invention is a fastener for jewelry that is composed of a pair of connectors that are detachable from each other, and the first connector is a cylindrical body and a cylindrical body that is housed inside the cylindrical body and faces toward the inner depth. The second connector includes a cylindrical elastic body having a plurality of elastic pieces that are normally biased toward the center by the previously formed cut, and the second connector has stoppers formed at both ends;
It is equipped with a slide shaft with a slide ring inserted so that it can move forward and backward, and when the second connector is fitted into the first connector,
The tip of the elastic piece of the first connector engages with the stopper at the tip of the second connector to prevent it from coming off, and when removing it, push the second connector further,
After the tip of the elastic piece is mounted on the outer periphery of the slide ring, by pulling out the second connector, the tip of the elastic piece of the first connector located on the outer periphery of the slide ring is attached to the second connector. It is characterized by being able to be pulled out by climbing over the stopper at the tip.

[Effect]

The accessory fastener according to this invention includes, for example, the first
The second connector is built into one end of the accessory chain or the accessory body, and the second connector is attached to the other end of the accessory chain for use.

〔Example〕

Next, one embodiment of the accessory fastener for the earring according to this invention will be described based on the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a fastener for an accessory, which is comprised of a pair of connectors that can be attached to and detached from each other.

The first connector 2 includes a cylindrical main body 11 and an elastic body 12 which is housed inside the cylindrical main body 11 and basically has a cylindrical shape. This elastic body 1
2, as shown in FIGS. 5 and 6, is provided with a notch 14 that extends in the axial direction toward the inner depth thereof, and has a plurality of notches 14 that are normally biased toward the center with the ends thereof open. It has an elastic piece 13.

Further, as shown in FIGS. 7 and 8, a notch 14 of the elastic body 12 is provided at the rear end of the cylindrical body 11.
A plurality of protrusions 15 are formed inwardly in accordance with this. The protrusions 15 engage with the notches 14 to hold the elastic body 12 within the cylindrical body 11.

As shown in FIG. 9, the second connector 3 includes stoppers 22 and 23 formed at both ends, and a slide shaft 21 with a slide ring 24 interposed therein so as to be movable back and forth. 25 is a connecting ring provided on the rear end stopper 23.

In this embodiment, the accessory fastener 1 includes, for example, a first connector 2 built into one end of the accessory chain or the accessory body, and a second connector 3 attached to the other end of the accessory chain. condition and ready for use.

That is, the slide shaft 21 is inserted into the first connector 2 and pressed. Then, as shown in Figure 1,
Elastic piece 1 of elastic body 12 built into first connector 2
As the slide shaft 21 passes through, the third tip engages with a stopper 22 at the tip of the slide shaft 21 and is prevented from coming off. At this time, the slide ring 24 moves backward on the slide shaft 21 and is stopped by the stopper 23 at the rear end.

Next, when releasing the attached state, as shown in FIG. 2, the slide shaft 21 is further inserted into the first connector 2 and pressed. Then, the tip of the elastic piece 13 of the elastic body 12 built into the first connector 2 comes to rest on the slide ring 24 . After that, when trying to pull out the slide shaft 21 in the opposite direction, the slide ring 24 is pulled out of the slide shaft 21 with the tip of the elastic piece 13 mounted thereon, as shown in FIG.
It slides on the top and comes into contact with the stopper 22 at the tip of the slide shaft 21.

When the slide shaft 21 is further pulled, the elastic body 12 moves on the slide ring 24, and as shown in FIG. 21, and the engagement between the first connector 2 and the second connector 3 is released.

[Effect of idea]

Since the accessory fastener of this invention is constructed as described above, it is possible to securely attach and remove the accessory simply by pushing the slide shaft of the second connector into the cylindrical body of the first connector.

Furthermore, since the fastener itself for accessories can be formed compactly, there is still room for free design of the connecting portion of the decorative body, and this has the effect that an excellent accessory can be formed.
