SUMMARY OF THE INVENTION The present invention is based on a fastener for an accessory which comprises a connecting member connected to one end of the accessory and a connected member connected to the other end of the accessory and hooked on the connecting member. On the premise of the stopper, the first invention is characterized in that the connecting member has a main body having a U-shaped hook formed at a tip thereof, and the connecting member is rotatably attached to the main body and moves within the hook to move the hook. A rotating member for opening and closing the opening, and a spring for urging the distal end side of the rotating member against the hook, in a state where the rotating member is pressed by a contact on the hook distal end by the spring; When the opening of the hook is closed, a wedge space that becomes thinner toward the contact is formed between the outer periphery of the rotating member and the inner periphery of the hook in the vicinity of the contact and inside the contact. It is characterized in that when the connected member inserted into the wedge space is moved toward the contact point, a force opposing the urging force of the spring on the rotating member is generated.

In a second aspect of the present invention, when the opening of the hook is closed while the rotating member is pressed against the contact between the hook and the rotating member by a spring, a portion near the contact and outside the contact is provided. The present invention is characterized in that the inner periphery of the hook is formed by a curve in a direction away from the outer periphery of the rotating member. The third blade pressure is characterized in that an angle sandwiching the intersection of the pivoting member and the base end of the hook is an obtuse angle.

[0006]

1 to 3 show an embodiment of the present invention. FIG. 1 shows a connecting member of the fastener. This connecting member forms a U-shaped hook 7 on the distal end side of the main body 6. The connecting member 6 is formed in a U-shaped cross section. A spring 8 is provided therein, and a rotating member 10 is attached via a shaft 9. The rotating member 10 is rotatable around the shaft 9, but is normally pressed against the contact point P on the tip end of the hook 7 by the elastic force of the spring 8.

[0007] At the end of the rotating member 10 is provided an attachment hole 11 for attaching one end of an accessory such as a necklace.
Are formed. A connected member (not shown) connected to the other end of the accessory is hooked into the hook 7 of the connecting member 6 for use. The connected member may be any ring-shaped member similar to the retaining ring 2 in FIG.

FIG. 2 is an enlarged view of the vicinity of the contact point P. On the inner side of the hook 7 from the contact point P, a wedge space 12 in which the inclined surface 7a inside the hook 7 and the inclined surface 10a of the rotating member 10 become narrower toward the contact point P is formed. In a portion outside the contact point P, the tip 7b of the hook 7 bends in a direction away from the rotating member 10 and protrudes.

Next, a method for attaching and detaching the above-described stopper will be described. When connecting the connected member to the connecting member 6,
First, an opening is made at the tip of the hook 7 by pressing the rotating member 10 with a finger. From there, if the member to be connected is put into the hook 7 and released, the rotating member 10 is pushed back by the elastic force of the spring 8 to close the opening.

However, in this embodiment, the hook tip 7b
Are protruded from the contact point P, so that the connected member can be hooked there and pushed in the direction of the arrow along the inner periphery of the hook 7 for easy connection. When the connected member passes through the contact point P, a force f opposing the pressing force of the spring 8 acts, so that the connection of the stoppers can be performed without having to push the rotating member 10 with one hand. it can. In particular, when the hook tip 7b
If the projection protrudes in a more distant direction, it can easily function as a guide, and the connected member can be more easily guided into the hook.

Hereinafter, a method of detaching will be described. Hook 7
The connected member inside is moved to the wedge space 12 near the contact point P. If the connected member is moved along the inner peripheral slope 7a of the hook 7 or the outer peripheral slope 10a of the rotating member 10, the connected member is caught in the wedge space 12, so that the connecting member 6 is located at a position where the connecting member 6 cannot be seen. However, the connected member can be naturally introduced into the wedge space. When the connected member enters the wedge space 12, the connected member can be pulled out in the direction of the arrow and pulled out from the hook 7. Also at this time, when the connected member passes through the contact point P, a force f opposing the spring force acts.

Therefore, when removing the necklace or the like, it is not necessary to perform a detailed operation of pushing the rotating member 10 of the connecting member by hand and opening the hook 7. With such a fastener, anyone can easily remove it. As described above, in order for the connected member to pass over the contact point P and generate a force opposing the pressing force of the spring 8, the wedge space 12 and the curve forming the wedge space 12 are formed. The shape is important. Slopes 7a and 1
Reference numeral 0a indicates that the connected member is guided to the wedge space 12 and is inclined so as to be easily moved to the contact point P. And wedge space 1
By gradually narrowing 2, the force for opening the gap is gradually increased in opposition to the pressing force of the spring 8 that presses the rotating member 10 against the contact point P.

FIG. 3 is an enlarged view of a portion A in FIG. 1, that is, around an intersection Q between the main body 6 of the connecting member and the rotating member 10. As is apparent from FIG.
Is an obtuse angle. If the angle θ is obtuse, the connected member connected to the hook 7 is less likely to be caught at the angle θ when the hook 7 is closed at the contact point P.
If the angle θ is an acute angle, the connected member may be caught when entering the angle θ. However, if the angle θ is an obtuse angle as in this embodiment, there is no portion of the closed hook 7 where the connected member fits except for the wedge space 12. That is, if the connected member is moved along the inner circumference of the hook 7, it can be guided naturally into the wedge space 12 without being caught by other parts. Therefore, removal becomes easier.

[0014]

According to the first aspect of the invention, when the connected member connected to the connecting member is released, the connected member can be easily pulled out without pushing the rotating member.
Since the detailed work of pushing the rotating member is no longer necessary, anyone can easily remove it. According to the second aspect of the invention, when connecting the connecting member and the connected member,
There is no need to push the rotating member, and the connected member can be easily fitted. According to the third aspect, there is no hooked portion in the closed hook, and when the connected member is removed, the hook can be guided to the wedge space more naturally. Therefore, the connected member can be more easily removed from the connecting member.
