[Problems to be solved by the device]

 Generally, this type of fastener has a length of 10 to 15 mm, and the lever 58 of the arm 55 protrudes from the side edge of the main body 54 by only about 1.5 to 2.0 mm. It is a very small one.

Since the fastener 50 disclosed in Japanese Utility Model Laid-Open No. 4-3016 and the like cannot rotate with one hand while gripping the main body 54, the operation of hooking the lever 58 with the fingernail and rotating the lever 58 is required. The main body is grasped by the fingertip of the left hand, and the lever 58 is rotated by the nail of the other hand, that is, the index finger of the right hand, and the engaging end 57 of the arm 55 is separated from the tip of the hook 53, so that the endless part of the fastener 50 is released. Open the annulus. The main body 54 is grasped by the thumb and middle finger of the same right hand while applying force with the fingertip so as to maintain this open state with the index finger of the right hand. Next, the left hand must insert the end ring 41 ′ at one end of the chain 41 of the ornament 40 or the other end of the cord or the end ring 41 ′ provided on any article from the tip of the hook 53. As described above, there is a problem that the operation is complicated and at the same time it is difficult to operate, and it takes a long time to install the device.

Further, even when the fastener 50 is removed, the body 54 is held down by one hand and the lever 58 is hooked by the other hand (especially when the necklace is worn). However, there is a problem in that these operations become very complicated because they are behind the scenes.

In addition, it is not easy to grasp the main body 54 with the fingertip of one hand while applying a force to the fingertip of the other hand with the very small lever 58, and the engaging end 57 of the arm 55 is fixed to the hook 53. Since it is difficult to maintain the state of being separated from the tip with one hand, there was a problem in that it failed many times and it was necessary to repeat the attaching and detaching operation.

Further, in the fastener 60 shown in Japanese Utility Model Laid-Open No. 6-41523, when the ornamental body 40 provided with the fastener 60 is attached to the body, the hooking portion 121 of the hook 12 is provided with only one hand. Since the endless annular body formed by the hooking portion 121 and the main body 61 can be released by pressing the spring 14 in the direction opposite to the biasing direction of the spring 14, in comparison with the former fastener 50, the latter fastener 60 is used. Although it is much easier to operate, the main body 61 is held between the thumb and the middle finger of one hand, and the hook 121 is resisted against the urging force of the spring 14 with the index finger of the same hand. In order to press and rotate to open the endless annular body, it is necessary to hold the main body 61 between the thumb and the middle finger so that the main body 61 does not move when a pressing force is applied to the hanging portion 121 with the index finger. On the other hand, if the hooking portion 121 is rotated too strongly, the tip of the hooking portion 121 comes too close to the outer edge of the main body 61, and the interval for inserting the end ring 21 into the hooking portion 121 becomes narrow. Therefore, the operation of inserting and hooking the end ring 21 into the hooking portion 121 with the other hand while maintaining the state where the endless ring-shaped body formed by the hook 12 and the main body 61 is appropriately opened is Since the fastener 60 itself is small and difficult to handle, there was room for improvement.

The present invention was developed to solve the above problems, and is formed at the other end of a cord band such as a chain of a decorative body, or the other end of the cord band or an end provided on any article. The purpose of the present invention is to provide a fastener that allows the ring to be attached and detached extremely easily and reliably. Particularly, the end ring can be easily attached to the hooking portion without directly operating the hook hooking portion with a fingertip. It is intended to provide a fastener that can be attached to and detached from a user.

The engaging end 131 of the trigger 13 projects outward from one end of the main body 11, that is, one end of the opening 18 in the longitudinal direction, while the hook 12 has a hooking portion. Reference numeral 121 denotes the other side edge of the main body 11, that is, the edge of the opening 18 at the one end side in the opposite direction to the protruding position of the engagement end 131 in the longitudinal direction of the opening 18. And the tips of the engaging ends 131 are engaged with each other in such a shape that they can be disengaged from each other.

As described above, the fastener 10 includes the curved inner edge of the hooking portion 121 of the hook 12, the edge of the opening 18 of the main body 11, and the inner edge of the engaging end 131 of the trigger 13. It is configured to form an endless annular body.

Further, as shown by the chain double-dashed line in FIG. 1, the trigger 13 is separated from the tip of the hook 121 by the tip of the trigger 13 and moves toward the center of the curved shape of the hook 121 of the hook 12 (that is, in the figure). It is provided so as to be rotatable in the clockwise direction on the paper surface of FIG.

On the other hand, as shown by the chain double-dashed line in FIG. 2, the hook 12 is hooked in the direction of the trigger 13, that is, the tip of the hooking portion 121 is separated from the engaging end 131 to the outside of the main body 11. The rear end side (base side of the hook) of the part 121 is provided so as to be rotatable in a direction approaching the engaging end 131 (counterclockwise direction on the paper surface of FIG. 2).

Further, between the two opposing plate pieces forming the base portion 132 of the trigger 13, a coil spring 14 is wound around the support shaft 15, and the hook 14 is wound by the spring 14. The trigger 13 is urged to rotate in a direction away from each other, and the tip of the hooking portion 121 of the hook 12 and the engaging end 131 of the trigger 13 are always engaged. For example, a hooking portion 123 [FIG. 4 (A)] having a uniform step in the thickness direction of the hook 12 is formed on the side edge of the boundary portion between the hooking portion 121 and the base portion 122 of the hook 12, and the hooking is performed. A locking portion 16 (FIG. 5A) that abuts the locking portion 123 at a position where the tip of the portion 121 engages with the tip of the engaging end 131 is formed on the edge of the web 111 of the main body 11. The locking portion 16 stops the pivoting operation of the hook 12 by the urging force of the spring 14.

On the other hand, a locking portion 136 [FIG. 6 (A)] that forms a uniform step in the thickness direction of the trigger 13 is formed on the web side edge of the trigger 13, and the tip of the engaging end 131 is a hooking portion. An engaging portion 22 (FIG. 5A) that abuts the engaging portion 136 at a position where it engages with the tip of the 121 is formed on the edge of the web 111 of the main body 11, and the trigger 13 by the urging force of the spring 14 is formed. The rotation operation of is stopped.

Further, the trigger 13 may pull the outer surface of the web 133 near the tip of the engaging end 131 by the inner circumference of the end ring 21 or press the outer peripheral edge of the end ring 21 to open it. . For this reason, it is preferable to form a recess 134 on the outer surface of the web 133 so that the end ring can be locked. For example, the concave portion 134 is formed inward from a virtual curve that smoothly connects the outer edge of the hanging portion 121 and the outer edge of the main body 11 in the plane of FIG. 1, and the concave shape is in the web thickness direction of the trigger 13. It can be installed so as to form a uniform shape toward.

As a mechanism for stopping the pivoting operation of the hook 12, as another example of the locking portion 16, a hook stopper 19 can be provided on the main body 11 as shown in FIG. The hook stopper 19 is located in front of the hook 12 in the rotation direction of the hook 12 by the urging force of the spring 14, and at the position where the tip of the hooking portion 121 of the hook 12 and the engaging end 131 of the trigger 13 engage with each other, the base of the hook 12 extends. It abuts against the side edge of 122 to stop the pivoting movement of the hook 12.

Further, as a mechanism for stopping the pivoting operation of the trigger 13, as another example of the locking portion 22 described above, a trigger stopper 23 can be provided on the main body 11 as shown in FIG. . The trigger stopper 23 is located in front of the trigger 13 in the rotation direction by the urging force of the spring 14, and contacts the side edge of the base portion 132 of the trigger 13 at the position where the tip of the hooking portion 121 and the engaging end 131 are engaged. Then, the rotation of the trigger 13 is stopped.

The hook stopper 19 and the trigger stopper 23 may be penetrated between the side plates 112 of the main body 11, and both ends or one ends thereof may be integrally fixed to the side plate 112 or welded thereto.

In FIGS. 1 and 2, the trigger 13 is formed so as to project from one of the webs 111 of the main body 11. The reason for this is that the hook tip 124 should be as thin as possible in use. Also, in order to make the entire hooking part 121 of the hook 12 a beautiful curved line in terms of external design, it is not desirable that the hooking part protruding from the main body be bilaterally symmetrical. 122 has a shape wider than the hooking portion 121 in order to have strength, and when the hook tip 124 is extended to the upper edge of one web 111 of the main body 11, the hook tip 124 becomes the base 122. There is no choice but to take a similar shape, which cannot satisfy both the above requirements for use and design. Therefore, by forming the portion corresponding to the base portion 122 in a symmetrical and identical shape and forming the overall shape in a substantially left-right symmetrical manner, it is possible to obtain a balance in the overall design of the hook 12. When the recesses 134 are not formed in the web 133 of the trigger 13, they are symmetrical.

Next, the operation of the above-described embodiment will be described below. When wearing a necklace ornament 40 composed of a noble metal chain with the fastener 10 of the present invention at one end, in FIG. 1, both sides of the main body 11 are clamped by the thumb and the index finger of one hand, and the other side of the body 11 is held. The end ring 21 provided at the other end of the ornament 40 is grasped by hand, and the inner peripheral edge of the end ring 21 is hooked in the recess 134 of the engaging end 131 to hold the trigger 13 as shown by the chain double-dashed line in FIG. Pull in the direction of rotation of the hanging portion 121 toward the center of the curved shape. The trigger 13 rotates to the two-dot chain line in FIG. 1 against the urging force of the spring 14, and the endless end formed by the opening 18 of the main body 11, the hooking portion 121 of the hook 12 and the engaging end 131 of the trigger 13.
