DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper mainly used for accessories.

[0002]

2. Description of the Related Art A fastener and a cord-like jewelry including the fastener are:
As seen in fasteners such as jewelry such as necklaces and key holders with chains, simple ones include coiled spring wires wound in a coil shape. In this case, a method is used in which the overlapping lines are pushed apart and the ring to be fastened is forcibly pushed through the gap.

In addition, a ring-shaped stopper is composed of a main body and a movable piece, and the movable piece moves along the circumference to form an opening in a part of the circumference of the ring. Insert through the opening. This movable piece has a ring-shaped stopper always closed by a thin spiral press spring built in the main body of the stopper, and a small protrusion provided on the movable piece is An opening is formed in the ring by hooking the fingernail and pressing the movable piece along with the spiral pressing spring along the circumference of the ring.

[0004] The ring to be fastened must be inserted from the gap of the opening of the stopper while keeping the opening of the stopper closed, and the protrusion provided on the movable piece is small. There are also difficult to operate.

Further, a band-shaped stopper is joined with a pin so as to bend into two at the middle point of the band, and a hook is connected to the tip of one of the bands, whereby the band is bent and the other band is bent. There is also a method in which a hook is hooked on the tip of the device to close the stopper.

In the case of this method, the degree of stopping of the hooking claw is greatly affected by the relative length relationship between the two bands and the spring property of the bands themselves, and there is a drawback that the hooks easily come off after long-term use.

The stopper described above is a first stopper 1
The second stop piece 3 can be freely closed or opened using the shared shaft 5 as a rotation axis.
By being able to be freely closed or opened, it functions as a stopper.

FIG. 3 is a perspective view of the stopper in a closed state. In the figure, 1 indicates a first stopper, 3 indicates a second stopper, and 5 indicates a fixed shaft. Reference numeral 91 denotes a single ring that forms a part of a chain or the like with which the stopper stops, and reference numeral 92 denotes a fixed ring that constantly connects the end of the chain to the stopper.

The stopper in the closed state is the first through hole 11
And the second through-hole 31 overlap because the interval between the common shaft 5 and the second through-hole 31 is the same. In addition, the positions of the first slit 12 and the second slit 32 are respectively
