DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a fastener for a necklace or the like, and more particularly to a structure of a fastener (clasp) for engaging a necklace, a bracelet, an anklet or the like in a loop.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 7, a part 61 of a ring portion 60 is slid by a convex portion 62 against the bias of a spring (not shown), or as shown in FIG. In general, a middle folding type in which the member 70b is folded back and then stopped after being passed through is used, and as other types, a plug-in type (see FIG. 8) and a fish hook type (see FIG. 9) are also known. Have been.

[0003]

However, since all of the conventional fasteners have a special form, they do not naturally blend into the appearance of a necklace or the like. Therefore, in the case of a necklace, the fastener is located behind the neck. The fact is that it is made inconspicuous.

[0004] Further, the engagement and the disengagement are troublesome, and this becomes more remarkable when the stopper is located behind the neck as described above.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a fastener structure for a necklace or the like which can be easily engaged and disengaged without obstructing the appearance of the necklace or the like. To provide.

It is another object of the present invention to provide a fastener structure such as a necklace which diversifies the types of fasteners.

[0007]

According to the present invention, there is provided a fastener structure for a necklace or the like according to the present invention. Providing each of the possible second ring portions,
By deforming the second ring portion, the second ring portion can pass through the first ring portion, and
The second ring portion is restored so that the second ring portion cannot pass through the first ring portion.

That is, after the second ring portion, which cannot pass through the first ring portion in the state of the normal ring shape, is deformed and passed through the first ring portion, the second ring portion is restored to the original shape. Then, a necklace or the like is used as a ring.

In the present invention, the second ring portion may be constituted by a pair of half ring portions.

[0010] A necklace or the like refers to a chain-shaped accessory such as a necklace, a bracelet, an anklet and the like.

As a mode for deforming the second ring portion,
For example, by using an elastic material such as rubber for at least a part of the second ring portion so as not to impair the appearance, various shapes such as crushing a perfect circular ring shape into an elliptical shape can be considered, but from the texture of an accessory, It is desirable that the second ring portion is made of the same material as that of the main body such as a necklace.

In addition, the mode of restoring the second ring portion includes both the mode of automatically restoring and the mode of restoring by modifying.

Further, both the first and second ring portions are not limited to a perfect circular shape, and may be, for example, a heart shape or the like.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an explanatory view showing a necklace 1 partially omitted. The necklace 1 includes a chain-shaped necklace body 1 ′ that substantially forms a collar, and a necklace body 1 ′.
And a second ring portion 20 provided at the other end of the necklace body 1 ', and an additional decorative portion 30 connected to the second ring portion 20 and hanging down to the chest.

As shown in FIG. 2, the second ring portion 20 includes a pair of left and right half ring portions 20a and 20b having the same half ring shape, and each of the half ring portions 20a and 20b.
On the upper end side, main body connecting portions 21a and 21b connected to the chain ring 2 corresponding to the end of the chain main body 1 'via holes 21a' and 21b '(see FIG. 3A), and on the lower end side. Are provided with decorative connecting portions 22a and 22b for connecting a chain ring 31 corresponding to the upper end of the additional decorative portion 30 via holes 22a 'and 22b' (see FIG. 3B).

Each of the main body connecting portions 21a and 21b has a ring shape defined by the second ring portion 20 (hereinafter referred to as "ring shape 2").
0 '". ) Protruding radially outward, each hole 21
a 'and 21b' are used to form the chain ring 2 into a ring shape 20 '.
While the decorative connecting portions 22a and 22b protrude in the circumferential direction of the ring shape 20 ′, and each of the holes 22a ′ and 2
2b 'passes the chain ring 31 in the radial direction of the ring shape 20'.

Therefore, in a state where the second ring portion 20 hangs down from the chain ring 2, each of the main body connecting portions 21
Due to the weight of the second ring portion 20 and the additional decoration portion 30, the upper and lower end portions 20a 'and 20b' of the half ring portions 20a and 20b also overlap with each other. In order to match, the second ring portion 20 always maintains the ring shape 20 ′ (hereinafter, this state is referred to as “normal state”).

The second ring portion 20 in the normal state has substantially the same size as the first ring portion 10 (about 7 mm in inner diameter).
The second ring part 20 cannot pass through the first ring part 10. From this normal state, each half ring portion 20a,
Upper end surfaces 20a ', 20b' of 20b and body connecting portion 2
When the overlap of 1a and 21b is released with a fingertip and the second ring portion 20 is deformed so as to fold each half ring portion 20a and 20b from the side as shown in FIG. 4, the second ring portion 20 becomes the first ring portion. It is possible to pass through the part 10 (hereinafter, this state is referred to as a “deformed state”).

Therefore, after passing the additional decorative portion 30 and the deformed second ring portion 20 through the first ring portion 10, the second ring portion 20 is returned to the normal state, so that the necklace main body 1 'can be connected to the collar. The second ring portion 20
The restoration from the deformed state to the normal state is performed by the second ring 20
Is lower than the chain ring 2, the main body connecting portions 21a, 21b automatically move to the lowermost position of the chain ring 2 by gravity, and the upper end surfaces 20a ', 20b'.
Do not require any special operation.

FIGS. 5A, 5B, and 5C are views from above of the change of the second ring portion from the normal state to the deformed state, in which case the chain ring 2 is viewed from within the vertical plane. Defeated into horizontal plane. The second ring portion 20 can pass through the first ring portion 10 before the half ring portions 20a and 20b are completely folded (during the deformation), and the deformation direction may be reversed.

Reference numeral 3 in FIG. 1 denotes a decorative ball for restricting the movement of the first ring portion 10 along the necklace body 1 'after passing through the second ring portion 20.

In the above embodiment, the second ring portion 20
Is a ring shape that can be naturally melted into the necklace 1, and is not a special form unlike a conventional fastener. Therefore, there is an advantage that it is not easy to determine where the stopper is viewed by another person.

The decorative connecting portions 22a and 22b may have the same structure as the main body connecting portions 21a and 21b.

[0025]

As described above, the structure of the fastener for a necklace or the like according to the present invention does not require a special form, and does not impair the appearance of the necklace or the like. Therefore, when the present invention is applied to a necklace, it is not necessary to position the first and second ring portions behind the neck. Also,
It is easy to engage and disengage the first and second ring portions, and a new method is given to the stopper.
