Description

The present invention relates to a fastener for jewelry, more specifically, a fastener for easily attaching a necklace, a bracelet or the like to a neck or a hand.

As a fastener for jewelry, particularly a necklace, a combination of a pulling ring 100 shown in FIG. 8 and a plate 110 that can be freely attached and detached is generally used. The pull ring 100 is attached with a ring 82b which is one end of the necklace chain 84 via a ring attachment portion 108 joined to the main body 102 in a U-shape. In addition, the plate 110 has a ring 82a which is the other end of the necklace chain 84 attached to a hole 116 formed in the end thereof.

In the pulling wheel 100, an arcuate slide bar 106 urged by a spring (not shown) is incorporated in a main body 102. A lever 104 is attached to the slide bar 106, and the slide bar 106 is interlocked with the movement of the lever 104. That is, when the lever 104 is moved in the counterclockwise direction indicated by the arrow J, the slide bar 106 is also moved in the counterclockwise direction indicated by the arrow K, and a gap is formed in the main body 102. The pulling wheel 100 and the plate 110 are connected by inserting a rectangular hole 112 formed in the plate 110 from the gap.

Since the slide bar 106 is urged by the spring in the clockwise direction indicated by the arrow K, when the lever 104 is released, the slide bar 106 returns to its original position, and the gap when the plate 110 is inserted disappears as illustrated. Thus, the plate 110 does not come off the pull ring 100 when the necklace 84 is worn.

However, in the prior art shown in FIG. 8, the operation of connecting and removing the pulling wheel 100 and the plate 110 is very difficult. Specifically, when connecting, holding the main body 102 of the pulling wheel 100 with one hand, turn the lever 104 counterclockwise with one hand, hold the plate 110 with the other hand, and form the hole 112 in the main body 102. It was necessary to pass through a small gap, and each hand had to move in two different directions. These movements are the same not only at the time of connection but also when removed, the pulling wheel 100 and the plate 110 are small in shape, and the attachment is often performed invisible behind the neck. The burden of the mounting and dismounting operations was large.

An object of the present invention is to solve such problems of the prior art, and to provide a fastener for jewelry that allows anyone to easily connect or remove a necklace or the like. In addition, the present invention provides a fastener for a jewelry embodying a so-called universal design concept so that as many people as possible can easily enjoy wearing a necklace or the like regardless of obstacles such as the elderly. For the purpose.

As a means for solving the above-mentioned problems, the present invention described in claim 1 includes a first connecting member connected to one end of a jewelry such as a necklace and the other end of the necklace. A fastener for connecting the jewelry in a ring shape by the first connecting member and the second connecting member, wherein the first connecting member is the first connecting member. And an opening / closing member that closes the gap, and the opening / closing member is urged in a first direction by an elastic member in the first direction and a linear direction opposite to the first direction. It is movable and is pivotally supported so as to be rotatable in a second direction substantially perpendicular to the linear direction and in the opposite direction, and the second connecting member is inserted into the insertion port of the first connecting member. With that force, the opening and closing member is rotated in the second direction and inserted. When the second connecting member is connected to the first connecting member from the gap serving as the opening, and the opening and closing member is pushed in the direction opposite to the first direction by the second connecting member, a gap serving as the insertion opening is formed. Thus, the first connecting member and the second connecting member are separated. Also,

According to the second aspect of the present invention, the second connecting member has a Y-shaped tip, and a shaft is attached to the inside of both ends. Connection and disconnection of the second connecting member are performed.

According to the present invention, anyone can easily connect or remove a necklace or the like. Therefore, since the burden on wearing is reduced, the effect that the frequency of use inevitably increases can be expected.
