Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ornaments such as necklaces composed of necklaces, bracelets, rings, loop ties, belts or other rope bodies.

[0002]

2. Description of the Related Art Ordinary accessories of this type are usually attached to a neck, an arm, a finger, or the like in a ring shape by fastening an annular accessory with a fastening member such as a ring. ing.

[0003] Of these, a general method of using a necklace is to attach a chain or a string-like portion around the neck and attach it around the neck with hooks or fasteners provided at both ends of the chain or the like. The endless necklace is wound in two or three turns so as to be worn around the neck.

[0004] However, these ornaments such as necklaces have extremely small and complicated fastening members, so that not only is it difficult to mount and remove them around the neck and the like, but also the diameter of the annular ornament is Since it is determined for each product, it cannot be used with its diameter arbitrarily expanded or contracted according to the user's preference.

On the other hand, since an endless necklace is originally used by being wound around the neck in two or three rows, it cannot be said that the necklace can be used by expanding and contracting the diameter of the necklace to an appropriate diameter. .

The inventor of the present invention has already disclosed Japanese Utility Model Laid-Open No. 4-36821 (Japanese Utility Model Publication) to solve the problem that the diameter of the annular ornament cannot be arbitrarily changed as described above. No. 7-34570). The ornamental products proposed in the publication and already implemented have been well received not only in Japan but also worldwide, and have become widespread before being positioned as one of new product items as ornaments.

The annular product (trade name: Moonray) proposed by the present inventor is widely used at present, but when a rope having a small diameter of about 1.5 mm is required. However, even when the magnet was magnetized to the extent possible, it was confirmed that the magnetic absorption reduced the magnetic absorption performance slightly due to the small diameter of the rope body.

[0008] Therefore, when such a thin rope body is used as a necklace, if sweat or the like adheres to the outer peripheral surface of the rope body during use, there is a possibility that the adsorption performance between the rope bodies is reduced. In addition, when the decorative body is hung below the annular body composed of the rope body, the weight of the decorative body causes the annular body to be deformed by applying a load, or even when the length of the adsorption portion of the rope body is short. Since there is a possibility that the adsorption performance may be reduced, both ends adsorbed on the rope body are separated from each other, so that there is a problem that the function as a necklace is impaired.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to maintain a suction performance even for a rope body having a small diameter. Another advantage of the present invention is that the shape memory function is maintained, the function as a decoration is effectively exhibited, and the annular diameter of the annular body can be appropriately adjusted according to the preference of the user.

And a holding member provided in the middle of the suction portion to provide a fastening performance and a free performance of adjusting the diameter of the annular body.

The invention according to claim 2 is such that an annular body having an appropriate diameter is formed by adsorbing an outer peripheral surface which is an adsorbing portion of the loop-shaped rope portion and an inner peripheral surface which is an adsorbing portion of the both-end rope portion. According to a third aspect of the present invention, the structure of the holding member has a structure in which a bent portion is formed in a pipe main body having an elliptical cross section to increase frictional resistance between the rope body and the inner peripheral surface of the pipe main body. The shape holding function and the adjustment of the annular diameter are enabled.

[0012] In the invention according to claim 4, the bent portion includes:
It has a structure consisting of a round portion provided at the center of the pipe main body and protruding portions provided at both ends, and is more excellent in holding and operability than the aesthetic appearance.
