Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to accessories such as bracelets, rings, and netcles made of pearls that are worn on the arm, finger, neck, etc. Specifically, the bracelet, etc. can be easily put on and taken off, and it fits snugly on anyone's arm, etc., regardless of the thickness of the arm, etc., and does not require the use of metal fittings that spoil the aesthetic appearance. It relates to improvements that allow it to be attached and detached.

[Conventional technology]

Pearl bracelets, rings, netskures, etc. are used as accessories. and,
A fastener is generally used as a means for attaching and detaching the bracelet etc. to the arm etc. In other words, bracelets and the like are formed by inserting pearls, ornaments, etc. into the concentric lines of a string or chain that have a certain length, but there are a pair of concentric lines at both ends of the concentric lines. The clasp is latched, and the bracelet or the like can be attached or removed by engaging both clasps with the bracelet wrapped around the arm or the like.

[Problem that the invention attempts to solve]

However, in the above-mentioned method of putting on and taking off bracelets, etc., putting on and taking off bracelets, etc. is done through the engagement of the stopper, which makes it very troublesome to put on and take off bracelets, etc. This has the first problem. For example, when a bracelet is worn on one arm, the clasp must be removed using only the hand of the other arm because that arm cannot be moved. Since the fasteners are generally compact, there is a problem in that it is very cumbersome to remove them with one hand.

In addition, if the bracelet, etc. is made to be larger in advance by having both ends of a bracelet, etc. formed with a certain length dimension hooked through a stopper, the bracelet, etc., is made larger in advance, and when worn on the arm etc. The second problem is that if the same bracelet is made to fit a specific wearer's arm, it cannot be worn on another person's arm. There are problems. That is, there is a problem in that it cannot be tightly fitted to the wearer's arm, etc., regardless of the thickness of the wearer's arm.

A third problem arises in that the use of the fasteners as described above impairs the aesthetic appearance of the jewelry.

This invention is an attempt to improve the conventional problems as mentioned above, and it is easy to put on and take off, has a wide tolerance for the thickness of the arm, etc., and fits snugly to the arm, etc. In addition, there is a problem to be solved in that it can be attached and detached without using fasteners that spoil the aesthetic appearance. That is, in the present invention, the core wire of the bracelet, etc. is formed using a resilient shape memory alloy instead of the conventional string, chain, etc., and the both ends of the bracelet, etc. are wound with a slight overlap. It is characterized by being able to solve the above problems, and its specific means and effects are as follows.

[Means for Solving the Problems] A core wire is provided which is wound into a substantially annular shape with both ends overlapping each other using a shape memory alloy having the property of being restored at a temperature equivalent to body temperature.

Pearls or pearls in which a large number of pearls have through holes penetrating the core wire, and ornaments with better thermal conductivity than pearls are inserted between the pearls, and blind holes are bored at both ends of the coaxial wire. Fix the above ornaments, etc.

[Effect]

When you unfold a bracelet etc. and put it on your arm etc.
The bracelet or the like can be tightly wrapped around the arm or the like through the restoring action of the core wire. That is, since the core wire is formed of a shape memory alloy that restores its shape at a temperature equivalent to body temperature, an effect that the expanded core wire restores itself due to temperature changes due to body temperature can be obtained.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described with reference to the illustrative drawings.

FIGS. 1 and 2 are drawings showing an embodiment of the present invention, and 1 indicates a core wire. The concentric wire 1 is formed using a shape memory alloy having restorability. That is,
The concentric wire 1 is formed into a linear shape using a shape memory alloy that has the property of restoring at a temperature equivalent to body temperature.
It is wound into a generally annular shape with a diameter that is approximately the same as the thickness of the arm, and both ends are overlapped with each other with an appropriate play width S.
The concentric wire 1 has a plurality of pearls 3 each having a through hole 2 in the diametrical direction, and a metal decoration that has better thermal conductivity than a pearl made of gold and formed into a spherical shell shape, for example. The articles 4 are inserted in an alternating succession or with ornaments 4 interposed at regular intervals. Furthermore, pearls 6 that form blind holes 5 are fitted into both ends of the concentric wire.

Next, its effect will be explained.

When you unfold the bracelet and pass your arm through it, your body heat will add an appropriate temperature to the core wire 1, and the concentric wire 1 will be restored to its original shape. Decorative items with excellent conductivity 4
By interposing the decorative item 4, body temperature can be well transmitted to the core wire 1 through the ornament 4, and the restoration action of the core wire 1 can be performed quickly. Then, due to the restoring action of the core wire 1, the bracelet contracts and automatically adjusts its diameter by the play width S according to the thickness of the wearer's arm, so that it fits snugly and engages with the wearer's arm. is obtained. In addition, the pearls 6 fixed to both ends of the concentric wire 1 provide a latching effect (the pearls 3
... and the function of preventing the ornaments 4 from falling off) and the function of concealing (the function of hiding both ends of the core wire 1) can be obtained.

Incidentally, in both embodiments, the explanation has been given by taking a bracelet as an example, but the present invention is not limited to this and can be applied to a ring, a necklace, etc. Moreover, although the case where the core wire 1 is wound in one or two layers has been described, the present invention is not limited to this, and it goes without saying that the coaxial wire 1 may be wound in three or more layers. It is also possible to wind the coaxial wire 1 into an elliptical shape. Further, in this embodiment, the ornament 4 made of gold and formed into a spherical shell shape is used, but the ornament 4 is not limited to this, and the ornament 4 can be made of, for example, platinum, silver,
It is also possible to form it from other metals or diamond, which has excellent thermal conductivity.

[Effect of idea]

The present invention is constructed as described above.
As mentioned above, the core wire of a bracelet, etc. is wound into a substantially annular shape using a shape memory alloy that has the property of recovering at a temperature equivalent to body temperature, with both ends overlapped with an appropriate play width, and the same shape is formed. By making it engage with the arm etc. through the restoring action of the memory alloy, there is no need for the troublesome engagement with a stopper like in the past, and the bracelet can be simply unfolded and passed through the arm etc. In addition to simplifying attachment and detachment, the diameter changes by the play width,
It has now become possible to fit the device snugly, regardless of the thickness of the wearer's arm.

In addition to making it possible to fit bracelets etc. on the arm etc. without using fasteners that spoil the aesthetic appearance, it is also possible to insert a large number of pearls, ornaments, etc. through holes in the core wire. In addition, blind holes are made at both ends of the concentric wire, and pearls, ornaments, etc. are fixed to completely cover the core wire, thereby further increasing its commercial value as an accessory. I've reached it.

In particular, in the case of the present invention, the core wire is coated by inserting a large number of pearls through the core wire and inserting an ornament that has better thermal conductivity than pearls between the pearls. Despite this, when wearing the bracelet, when the bracelet is unfolded and the arm is passed through it, body heat is well transferred to the core wire through the decorative item with excellent thermal conductivity, allowing the concentric wire to quickly recover. I was able to do it.
