[0002]

2. Description of the Related Art Conventionally, as a connecting tool used for a pearl jewelry such as a pearl necklace, as shown in FIG.
The one using a leaf spring is common. Such a coupling tool 2
0 is a hollow box-shaped female fitting 21 having an insertion hole 26 formed therein.
And a male fitting 22 formed by bending a metal plate into a V-shape to form a leaf spring.
4 is pressed down with a fingertip to form a flat male fitting 22
Is released from the insertion hole 26 of the female fitting 21 and the fingertip is released, thereby connecting the two using the elastic force of the leaf spring.

However, when the connecting tool 20 is normally located behind the neck, the tip of the leaf spring of the male fitting 22 is inserted into the insertion hole 26 of the female fitting 21 by checking the front and back surfaces of the male fitting 22. In some cases, the male fitting 22 and the female fitting 21 are positioned on the front face, and if necessary, they are connected with each other. Therefore, coupled with the necessity of a prior action of pressing the pressing piece 24 with a fingertip, the connecting tool 20 has a drawback that the operation at the time of mounting is difficult.

[0004] On the other hand, as a connector which has solved the above-mentioned difficulty in operation, a connector 30 using a coil spring as shown in FIG. 2 is disclosed. That is, a locking groove 35 is formed on the round bar-shaped peripheral surface of the locking tool 33 to which one end of the annular accessory main body 39 such as a pearl necklace is connected, and the other end of the annular accessory main body 39 is connected thereto. The coupling body 38 includes a cylindrical receiving member 31 through which the locking member 33 can be inserted and removed, and a locking member 36 that can be engaged with and disengaged from the locking groove 35 of the locking member 33. 38, an engagement / disengagement button 37 is provided outside the engagement groove 36.
And a coil spring 37a which is urged by an elastic force in a direction in which the coil spring 37a is locked (actually open flat 7-307).
No. 30).

However, in order to prevent a reduction in elastic force, the coupling tool 30 must use a coil spring 37a having a size equal to or larger than a predetermined value, which is stored in a cylindrical receiving member 31, and , The receiving member 31 must be stored in the connector body 38. Therefore, it is not easy to assemble the connecting tool 30 itself, and the connecting tool 30 is composed of a plurality of parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 3 is a perspective view showing a first embodiment of a connection fitting for an accessory according to the present invention, FIG. 4 is an exploded perspective view of the female fitting, and FIG. 5 is a sectional view showing the connection state. The attachment fitting 40 for the accessory according to the present embodiment includes a male fitting 42 made of a rod and a female fitting 50 made of a hollow box, and a hollow box-shaped lid 51 and a bottom body 60 can be opened and closed. The male fitting 42 can be inserted into and removed from the female fitting 50. The male fitting 42 and the female fitting 50 are respectively connected to both ends of an accessory such as a pearl necklace or a necklace chain, and are connected to form a ring for wearing.

Here, the male fitting 42 has a head 45 formed by tapering a main body made of a round bar at the tip.
A concave engaging groove 47 is provided on the entire periphery behind the head 45, a plate-like through hole is provided at the rear end, and a ring is attached to form a connection ring 49. A necklace thread protruding from both ends of a pearl necklace or the like after thread assembly is inserted and fastened into the through hole of the connection ring 49.

The female fitting 50 has a lid 51 having an open entire lower surface of the box and a lid 51 having an open entire upper surface of the box.
It is formed by a bottom body 60 having a predetermined size and shape that can be inserted into the bottom body 60. The lid 51 has an insertion port 57 with an inner diameter slightly larger than the outer diameter of the male fitting 42 at one end surface in the longitudinal direction.
Further, a cylindrical guide portion 54 having the same inner diameter as the insertion portion 57 is formed at two places on the bottom surface of the lid 51 inside the insertion opening 57. Also, the lid 51
In the figure, a substantially angled center portion of both side wall portions is extended downward to form a chevron 53, and the chevron 53 has a through hole 55 through which a support shaft 58 is inserted. A ring is attached to the other end of the insertion port 57 similarly to the male fitting 42 to form a connection ring 59.

The bottom body 60 has one end face in the longitudinal direction having an inner diameter engaging with the engagement groove 47 of the male fitting 42, that is, a dimension slightly smaller than the outer diameter of the male fitting 42, and a substantially semicircular shape from above. Is formed with a notched locking concave portion 61.
Further, a plurality of linear irregularities are formed on one side of the surface of the bottom body 60, and a pressing portion 62 for preventing slip is formed. Further, a through hole 65 is formed substantially at the center of both side walls of the bottom body 60, and the rear side is inclined to form a gentle slope.

A substantially U-shaped coil spring 67 whose tip is bent upward by 90 degrees is accommodated in the lid body 51 and the bottom body 60, respectively. 58 penetrate to form a hollow box shape as a whole.
Further, since the support shaft 58 is also inserted into holes on both sides of the coil spring 67, the coil spring 67 is fixed in the hollow box shape.

In this state, the lid 51 and the bottom 60 can be opened and closed, and the tip and the center of the disposed coil spring 67 press the bottoms of the lid 51 and the bottom 60 from inside. Therefore, the lid body 51 and the bottom body 60 are
7, the insertion opening 57 and the locking recess 61 are urged in the closing direction.

In order to use the connection fitting 40 for the accessory in this embodiment, when the tip of the male fitting 42 is inserted from the insertion opening 57 of the female fitting 50, the head 45 is formed into a tapered shape, so that the bottom is formed. The body 60 can smoothly enter while being pushed down from the locking recess 61. And furthermore, the male fitting 42
