Description

[Detailed Description of the Invention] The present invention relates to a fastener for accessories such as necklaces and pendants.

A clasp for a pearl or other necklace generally consists of a clasp to which a pearl or other accessory is attached, and an insert that is removably inserted into the clasp. Conventionally, most of the structures have been of the so-called horizontal insertion type, in which the insertion tool is stopped and inserted into the entire body from the side.

Therefore, with such side-loading clasps, the user must hold the clasp body and the insert with both hands, hold the insert behind the neck, and grope into the small opening in the entire body while using one hand. It is difficult to insert the insertion tool because it is inserted from the side while pressing the spring, and if you are not used to it, you cannot insert it in one go, and you usually have to repeat it 2 to 3 times. It is very inconvenient as it is often impossible to put it on or take it off when it is put away.The present invention was made to alleviate this inconvenience of the conventional method. This is a completely new stopper for jewelry that can be inserted into the top and bottom without having to remove it, and the attachment and detachment of the entire stopper body and the insertion tool can be done easily and quickly with just a light push from above, almost a touch. This is what we provide.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In Figures 1 to 3, 1 generally indicates the entire body of the stopper;
Further, 2 generally indicates an insertion tool 2 that is inserted into the entire body of the stopper in a vertically fitting manner.

Thus, the entire stopper body 1 has a bottom edge 4 that defines the bottom opening 3.
The hollow body has windows 5 on both sides cut out from the bottom side thereof.

The stopper main body 1 also has an ornament such as a pearl attached to its upper surface 6, and a plurality of beads to which one end of a string of beads, such as a large number of pearls, is tied to one side. A connecting ring T is attached by a suitable method such as welding.

On the other hand, the insertion tool 2 has its bottom opening 3 inside the stopper body 1.
It is removably inserted through the connector, and has the following structure.

The insert 2 includes a hollow body 10 formed by a case 8 and a base 9, the case 8 having side windows 11 larger than the side windows 5 of the stopper body 10.

The case 8 and the base 9 are connected by a connecting member 12 such as an eyelet or a rivet, and this connecting member has a head 12.
a to the outside of the base 9 and the center hole 9a and the case 8.
is inserted into the central hole 8a of the shaft, and then the shaft end 12b is caulked.

The base 9 also has a vertical edge 9b on the opposite side of the stop body 1 from the side with the connecting ring T, and a plurality of connecting rings 1 to which the other end of the string is tied.
3 is installed.

The insertion tool 2 also includes a pair of operating pieces 14 disposed inside both sides of the insertion tool main body 100, and a pair of springs 15 interposed between these operating pieces.

Each operating piece 14 has a long protruding end 16 that passes through the window 11 of the insertion tool main body 10 and extends to the outside of the window 5 of the entire main body 1, and a long projecting end 16 that is formed on both sides of this long projecting end. It has a short protruding end IT extending to the outside of.

The short protruding ends 17 of these actuating pieces 14 are inserted against the force of the spring 15 by sliding contact with the bottom edge 4 when the insertion tool 2 is stopped and inserted into the entire body 1 through its bottom opening 3. Although it is once pushed into the window 11 of the insertion tool main body 10, the bottom edge 4 climbs over these short protruding ends 1T and rests on the base 9, so that it is pushed out again from the window 11 of the insertion tool main body 10 by the force of the spring 15. and is hooked on the inside of the bottom edge 4, thereby locking the insertion tool 2 to the stopper body 1.

To release this lock and lock the insertion tool 2 and remove it from the entire body 1, the long projecting end 16 of the actuating piece 14 is pushed in artificially against the force of the spring 15, thereby causing the short projecting end 1
7 into the window 11 of the insertion tool body 10 in the same manner against the force of the spring 15.

The operation of attaching and detaching the insertion tool 2 to and from the main body 1 is mostly done by just touching it.

The long projecting end 16 of the actuating piece 14 is formed in an L-shape, and its pushing surface is knurled as shown by reference numeral 18 in FIG. 1 to facilitate pushing.

As described above, according to the present invention, the insertion tool that is removably inserted into the entire stopper body is fitted through the bottom opening formed in the entire stopper body, so that the user can It is much easier to connect the entire main body of these clasps and the insertion tool behind the neck compared to the conventional horizontal insertion type.
It will be very convenient.

Moreover, the attachment and detachment of the main body of the stopper and the insertion tool can be performed simply and quickly with almost one touch, which is extremely convenient for the user.
