  In the clasps shown in FIGS. 2 and 11, the female portion 21 and the male portion 22 are coupled, and in order to separate, the locking piece 24 needs to be rotated to close or open the upper portion of the bar portion 23. There is. Then, the male portion 22 needs to be inserted into the portion of the bar portion 23 from above at the time of coupling, and the male portion 22 needs to be separated above the bar portion 23 at the time of separation.

  In this way, the coupling and detachment of the female part 21 and the male part 22 not only limit the direction and angle of attachment and detachment of the male part 22 to and from the female part 21, but also require rotation of the locking piece 24. In particular, when the male part 22 is mounted, the locking piece 24 must be rotated while holding the male part 22 in a state where it is set on the bar part 23 so that it does not come off. Such operations are performed in places where the eyes cannot be seen directly, such as behind the neck, or in places where the user must work with one hand, such as the wrist, which is not convenient.

  In the insertion type clasp using the spring shown in FIG. 10, the connector 20 is normally positioned behind the neck, and the tip of the leaf spring of the male fitting 22 is inserted into the insertion hole 26 of the female fitting 21. The front and back surfaces of the metal fitting 22 must be confirmed and inserted. If necessary, the male metal fitting 22 and the female metal fitting 21 are positioned on the front surface, and both of them may be connected while visually observing. Therefore, coupled with the need for a prior action of pressing the pressing piece 24 with a fingertip, the connecting tool 20 has a drawback that it is difficult to operate at the time of wearing.

  Although not shown in the drawings, there is a screw type in which two connecting members are screw-coupled. However, there is a drawback that operation at the same time is difficult.

  The object of the present invention is to provide a clasp that eliminates the disadvantages of the conventional example, can easily and stably connect the ends of the accessory, and also has a good appearance and a beautiful appearance as part of the accessory. There is to do.

  In order to achieve the above object, the present invention according to claim 1 is an insertion-type clasp composed of a female part and a male part combined with the female part, wherein the female part is formed in a cylindrical shape, and the male part is formed of the female part. A lid that bears the appearance continuous to the female part is formed in a bowl shape at the end of the columnar body that fits inside, and a plate spring that springs up from the lid is provided on the columnar body. The gist is provided with a locking projection, a hole is formed in the female portion, and the base end of the leaf spring is raised to provide a pressing button.

  According to the first aspect of the present invention, in the insertion type clasp constituted by the female part and the male part combined with the female part, the female part is firmly inserted into the female part by inserting the columnar body part. Fits and is combined. In addition, since the male part is formed in the shape of a bowl that bears the appearance that continues to the female part, the female part and the female part are joined together in a continuous state, and the clasp part looks as if it is an accessory piece. Have. As a result, there is no sense of incongruity even when the clasp portion comes not in the back of the neck but in the front.

  Furthermore, since the male part is not a single spring, but a plate spring that springs up from the columnar body is provided on the columnar body, the spring is supported by the columnar body and is stable.

  To remove the clasp, press the push button to release the latch on the leaf spring and pull out the columnar body from the female part. Since there is a portion, it can be performed stably, and the whole can be made small.

  The push button, which is the part that pushes the engagement protrusion, is easy to push because it is at the root end of the leaf spring (the largest jumping part on the opposite side of the fixed part at the tip), and it is easy to confirm even if it is not visible when removed.

  The gist of the present invention described in claim 2 is that the columnar body portion is formed by arranging two wires.

  According to the second aspect of the present invention, when forming as a very small clasp for use in a thin chain, the male columnar body portion is also thin, and this is formed by arranging two wires. Thus, it is possible to easily form a columnar body portion with grooves.

  The gist of the present invention described in claim 3 is that the columnar body portion is formed with a groove in the circumferential length direction and a leaf spring is disposed in the groove.

  According to the third aspect of the present invention, the leaf spring is placed in the groove to release the latch of the leaf spring by pressing the push button by disposing the leaf spring in the groove formed in the surface length direction of the columnar body portion. And keep it out of the way.

  As described above, the clasp according to the present invention can easily and stably connect the ends of the accessory, and can have a good appearance and a beautiful appearance as a part of the accessory.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of a clasp coupled state according to the present invention, and FIG. 2 is a side view of a released state, and an insertion-type clasp comprising a noble metal female portion 1 and a noble metal male portion 2 combined with the female portion 1. It is.

  The female part 1 is a cylindrical body having a closed end and an open end and having a cavity 3 formed therein, and a locking ring 4 such as a chain is formed on the closed end side.

  Further, a band-like long groove was formed in the circumferential direction on the peripheral wall near the opening end, and this was used as the locking hole 5. In the example shown in the drawing, the locking hole 5 is pulled out from the inside to the outside. However, the locking hole 5 may not be opened to the outside but may be kept inside.

  The male part 2 has a columnar body 6 that fits inside the cavity 3 of the female part 1, and a lid 7 that bears the appearance continuous to the female part 1 at the end of the columnar body 6. Was formed into a bowl shape.

  To bear the appearance that is continuous with the female part 1 is to make the appearance of the female part 1 the same as that of the female part 1 so as to become a part of the female part 1. In the illustrated example, since the female part 1 is a cylindrical body, the lid body 7 is also a similar short cylindrical body. A locking ring 4 is also formed outside the lid body 7.

  The clasp of this embodiment is extremely small, and the female portion 1 is formed by brazing the columnar body 6 with two thin wires (round wires) 8 arranged side by side as shown in FIG. The wire 8 has a circular cross section, and a groove 9 is formed as a trough on the upper surface. By making the linear shape of the wire (round wire) 8 0.4 mm, the entire clasp can be made thin, and the outer shape of the clasp can be formed to a minimum of 1.5 mm.

  In the figure, reference numeral 10 denotes a leaf spring, but the tip end was brazed and fixed to the tip of the columnar body 6 and the columnar body 6 was installed as a base so as to jump up above the groove 9.

  The female part 1 is a cylindrical body having a closed end and an open end and having a cavity 3 formed therein, and a locking ring 4 such as a chain is formed on the closed end side. In the present embodiment, the locking ring 4 is not formed as a protrusion, but is formed in a shape in which a notch groove is formed and closed.

  Further, a band-like long groove was formed in the circumferential direction on the peripheral wall near the opening end, and this was used as the locking hole 5. In this embodiment, the locking hole 5 is opened only on the inner side and not on the outer side.

  The male part 2 has a columnar body part 6 made of a cylinder that fits inside the cavity 3 of the female part 1, and a lid that bears the appearance continuous to the female part 1 at the end of the columnar body part 6. The body 7 is formed in a bowl shape.

  To bear the appearance that is continuous with the female part 1 is to make the appearance of the female part 1 the same as that of the female part 1 so as to become a part of the female part 1. In the illustrated example, since the female part 1 is a cylindrical body, the lid body 7 is also a similar short cylindrical body. A similar locking ring 4 is also formed outside the lid body 7.

  In the present embodiment, the male part 2 has a groove 9 in the circumferential surface length direction of the columnar body 6, and a leaf spring 10 is disposed in the groove 9.

  The leaf spring 10 was bent at the tip end downward and inserted into the hole of the columnar body 6 and fixed up, jumped up along the groove 9, and installed with the columnar body 6 as a base.

  The leaf spring 10 was raised with the leaf spring base end bent, and a dish-like pressing button 11 was provided at the tip.

  Further, the leaf spring 10 is provided with a triangular locking projection 12 facing upward slightly to the near side of the root end to be bent. The locking projection 12 is engaged with the locking hole 5 of the female portion 1.

  The usage is substantially the same as in the first embodiment, and the description is omitted.

  In the example shown in FIG. 9, the entire clasp is not a cylinder, but an oval shape (football shape). In this case, the lid 7 of the male part 2 has a curve that is continuous with the outer shape of the female part 1. By having it, it will bear the external appearance continuous to the female part 1.
