DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coupling mechanism for a decorative accessory suitable for a ring-shaped accessory of a type used by being wrapped around a neck, arm, wrist, ankle or the like of a necklace, a bracelet, an anklet or the like.

[0002]

2. Description of the Related Art A conventional ring-shaped accessory for a necklace, a bracelet, an anklet, or the like, which is used by being wrapped around the neck, arm, wrist, ankle, or the like, is provided with a pull ring pin in a hole of a perforated plate. In addition to a general fitting to be engaged, a fitting having permanent magnets at both ends of a ring, a fitting in which a leaf spring is fitted into a fitting to prevent it from coming off, and the like are known.

[0003]

However, in the conventional connecting mechanism for personal ornaments, there is no problem when the personal accessories such as necklaces, bracelets, and anklets are made of chains, but the personal accessories main body has such flexibility. If it is made of precious metal elastic material,
For example, in the case of a rod-shaped precious metal, it is difficult to perform a connection operation with a general metal fitting that engages a pin of a pulling ring with a hole of a perforated plate, and the accessory body of the perforated plate or the pulling ring. There was a problem that it was difficult to attach to the. In addition, since the jewelry body is made of an elastic material and a load is always applied to the joint part of the jewelry body, the connection is easily disconnected when the permanent magnet is provided at both ends of the ring, and the load is applied to the permanent magnet part. There has been a drawback that it is damaged by being hooked or detached from the accessory main body. Further, in the structure in which the leaf spring is fitted into the metal fitting to prevent the leaf spring from coming off, there is also a problem that the leaf spring is subjected to a load during use and is easily damaged.

The connecting mechanism for personal ornaments of the present invention is intended to solve the above-mentioned disadvantages of the prior art. The connecting operation is extremely simple, the main body of the personal accessory is made of an elastic material, and a load is always applied to the connecting portion of the personal accessory. An object of the present invention is to provide a connection mechanism for accessories which is hard to be disconnected even if it is hung and is hard to be damaged during use.

[0005]

That is, a connecting mechanism for an accessory according to the present invention comprises a ring-shaped accessory having a ring-shaped accessory body partially open and a pair of connecting mechanisms provided at the open end. One of the coupling mechanisms has a hook portion having a T-shaped cross section, and the other coupling mechanism comprises a cylindrical housing, and a T-shaped notch is formed on an inner peripheral surface of the cylindrical housing. Are formed, slide guides are provided on both sides of the notch, and a stopper for engaging the hook is formed at the open end of the cylindrical housing, and the hook is fitted into the notch. , The inside of the tubular housing is slid toward the opening end, and the hook is engaged with the stopper to prevent the hook from coming off.

According to the accessory attachment mechanism of the present invention, the connection operation is extremely simple, the attachment is made of an elastic material, and the connection is hard to be disconnected even if a load is constantly applied to the connection portion of the accessory body. It has become possible to provide a connection mechanism for accessories that is not easily damaged during use.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a connecting mechanism for an accessory according to the present invention.

FIG. 1 is a front view showing an example of an accessory such as a necklace to which the connecting mechanism for an accessory of the present invention is attached, FIG. 2 is an enlarged perspective view of a main part thereof, and FIG. 3 is a perspective view of the disassembled state as viewed from above. 4 is a perspective view as viewed from below, FIG. 5 is a bottom view thereof, and FIG. 6 is a sectional view thereof.

In FIG. 1 to FIG. 6, reference numeral 1 denotes a ring-shaped accessory main body having a partially open shape. The ring-shaped accessory main body 1 has a cross section of a plate shape, a round bar shape, a square bar shape, or the like.
It is formed of a precious metal elastic material. Therefore, the ring-shaped accessory main body 1 can be bent so as to open and close its open end, and is normally urged in a direction in which the open end expands.

At the open end of the ring-shaped accessory main body 1,
A pair of coupling mechanisms 2 and 3 are provided, respectively. One of the connecting mechanisms 2 is formed into a hook portion 4 having a T-shaped cross section by processing the ring-shaped accessory main body 1 itself. The hook portion 4 having the T-shaped cross section can be appropriately formed in accordance with the cross-sectional shape of the ring-shaped accessory main body 1, but is preferably a protruding piece having a predetermined width as shown in the figure.

The other connecting mechanism 3 has a cylindrical housing 5, and an inner peripheral surface of the cylindrical housing 5 has
A T-shaped notch 6 into which the hook portion 4 is fitted is formed. On both sides of the notch 6, a slide guide 7 formed in a slit shape with a width smaller than the width of the hook portion 4.
After the one connecting mechanism 2 is fitted in the T-shaped notch 6, the hook 4 can be slid toward the distal end of the cylindrical housing 5 while the hook 4 is prevented from falling off by the slide guide 7. it can. The cylindrical housing 5
A stopper 8 for engaging the hook 4 with the open end of
Are formed.

Therefore, from the state where the pair of connecting mechanisms 2 and 3 in FIGS. 3 and 4 are opened, the hook portion 4 is stored in the T-shaped notch 6 as shown by the dashed line in FIGS. Then, since the ring-shaped accessory main body 1 is urged in the direction of expanding the open end by its elasticity, the T-shaped hook portion 4 slides toward the distal end of the cylindrical housing 5 while engaging with the slide guide 7. The hook portion 4 engages with the stopper 8 and is stopped at the position indicated by the solid line in FIGS.

Of course, when the connection between the pair of connecting mechanisms 2 and 3 is released, the hook 4 is engaged with the slide guide 7 against the elasticity of the ring-shaped accessory main body 1 in the opposite direction. The hook portion 4 may be slid in the depth direction of the housing 5 to remove the hook portion 4 from the T-shaped notch 6 at a position passing through the slide guide 7. At this time, since the ring-shaped accessory main body 1 is urged in a direction to expand the open end by its elasticity, the open end is automatically opened.
Therefore, it is possible to provide a connection mechanism for accessories which is very easy to operate.

In the above embodiment, a necklace has been described as an example, but it goes without saying that the present invention can be applied to ring-shaped accessories such as bracelets and anklets other than necklaces.

[0015]

According to the accessory attachment mechanism of the present invention,
An object of the present invention is to provide a connection mechanism for an accessory that is extremely easy to connect, the connection of the accessory body is made of an elastic material, and the connection is difficult to be disconnected even if a load is constantly applied to the connection portion of the accessory body, and the connection mechanism is hard to be damaged during use. Is now available.
