Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ornament, and more particularly, to an ornament such as a necklace or a bangle formed in a ring shape which has no connection stopper and can be in close contact with the body (skin). is there.

[0002]

2. Description of the Related Art Conventional necklaces and bangles (bangles refer to bracelets and anklets, that is, bangles and ankles) generally require connection fasteners for attachment (detachment). However, recently, jewelry using a rubber or a string for a ring and having no connection fastener has been marketed. However, in the case of a jewelry using rubber or a string for the ring, it is difficult to give the product itself a high-quality and high-grade feeling, and thus the commercial value is low.

On the other hand, there is an accessory using a metal wire having an excellent elasticity for a wheel. In this case, the decorative object is limited to a lightweight one because it easily falls with a single wheel. Therefore, when using a decorative object with a large mass, such as pearl, glass, or crystal, it is necessary to wrap it more than once or use a rigid metal. The one used is troublesome in attaching and detaching to and from the body, and may be painful depending on the object, which is not preferable.

[0004] In the case of a jewelry using a magnet, the magnet must be in contact with the skin in order to enhance its value as a health product. It is ideal. However, the conventional one using a magnet ball having a mass almost equal to that of a pearl or crystal requires a single or more wrapping or the use of a rigid metal as in the case of the above, and a connection fastener that impairs aesthetic appearance. Was required.

Further, using a spring material having a restoring property,
In the case of a substantially ring-shaped wound ring bracelet or the like in which a stopper is removed, the attachment and detachment is easy, the allowable range of the thickness of the arm and the like is wide, and the connection fastener that impairs aesthetic appearance can be eliminated. Although it is improved, a large force is required to expand the ring due to the elastic strain and the elastic stress of the spring material, and a sufficient tightening force on the arm or the like does not allow a sufficient fit to be achieved. Pleasant to feel. Moreover, when the attachment and detachment of the ring are repeated, the amount of elastic strain is large, so that not only the ring becomes large, but also it is easily broken.

In order to solve such a problem, Japanese Patent Laid-Open Publication No. 1-110303 proposes an accessory using a NiTi superelastic alloy for a wheel. At room temperature, at room temperature, a metal alloy wire having a property of exhibiting a superelastic effect is formed into a substantially annular shape by overlapping both ends with a winding ring, and a connection fastener that impairs aesthetic appearance. It can be attached and detached without using any other means, and an effect such as not requiring a large force to expand the ring is obtained.

[0007]

However, in the case of the conventional accessories which can be detached without using the above-mentioned connection fasteners, the adhesion to the body is not sufficient, and the ring is single-layered and hard to drop. Also, it was not easy to make a bracelet or the like that was easy to put on and take off. Further, the conventional one has a problem that it is not easy to arrange decorative objects such as beads at equal intervals. That is, as a method of arranging decorative objects at equal intervals, a method of processing the decorative objects so as to maintain the connection interval is generally used. However, if the decorative objects are simple beads, it is not possible to leave a bead interval. The length of the string or the like, that is, the size of the ornament is determined according to the size and number of the beads. If the string is a little long, the string is exposed and becomes poor at that part, so that it is very difficult to set the bead interval.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional accessories, and has good adhesion to the body, and has a single annular shape and does not have a connection fastener. It is an object of the present invention to propose an ornament which is easy to manufacture and can easily arrange decorative objects at equal intervals, is excellent in design and decoration, and a method of coating the decorative object.

[0009]

SUMMARY OF THE INVENTION The present invention relates to an ornament using a magnet as a decorative object, having a single loop (ring) and no connecting fastener. To
The second embodiment is characterized in that decoratively processed magnets are attached alternately or every few pieces in a direction to repel, and are formed in a single substantially annular shape without using connection fasteners. The alloy wire is made of a nickel titanium superelastic alloy having a wire diameter of φ1.0 mm to φ1.8 mm and is formed in a single substantially annular shape. The third embodiment is characterized in that a transparent urethane rubber wire is provided with a decoration. The magnetically processed magnets are mounted alternately or every few magnets in a direction to repel, and the transparent urethane rubber wire is formed in a single substantially annular shape without using connection fasteners to form a ring. In the fourth embodiment, the transparent urethane rubber wire has a linear shape of φ1.2 mm to φ1.7 mm.
The transparent urethane rubber is used, and both ends of the urethane rubber wire are connected by heat fusion.Fifth embodiment is a magnet bead whose surface is coated with a paint containing a polyimide resin as the magnet. The sixth embodiment is a method of coating a surface of a magnet with a paint containing a polyimide resin, the gist of which is as follows.
Arrange a magnet magnetized in advance on an iron block having an electromagnet structure, paint one side of the magnet with a paint containing a polyimide resin, and then immediately reverse the magnet by changing the polarity of the electromagnet The remaining one side is painted.

In the present invention, the magnet is used for the decorative object because the decorative object can be easily arranged at equal intervals by utilizing the repulsive force of the magnet, and an effect as a health goods is expected. Because it is.

The reason why the nickel-titanium superelastic alloy and the transparent urethane rubber are used as the material of the ring is as follows. First, a nickel-titanium superelastic alloy (containing about 50% by weight of nickel and having an austenite phase at room temperature) is used because of its rigidity as a metal material,
This is because they are excellent in all aspects of elasticity and rust prevention. In addition, as the thickness, it is necessary to select a shape that fits perfectly to the arm, neck, and foot, that is, a line thickness that can be manufactured at least close to the cross section of each part of the body,
As a result of various studies, at least φ1.0 mm or more, φ
1.8 mm or less, preferably φ1.3 mm or more and 1.7 m
It has been found that a wire diameter of m or less is most preferable. The reason is that if it is less than φ1.0 mm, it will easily fall off,
If the thickness exceeds 1.8 mm, the elasticity of the wire is so strong that it is difficult to attach and detach, and since the elasticity is strong, it is difficult to process it into an arbitrary shape or to perform heat treatment. This is because the amount is large, which is not economically preferable.

The reason why a highly transparent urethane rubber is used as the other wire material is that it is excellent in stretchability, durability and luxury. Urethane rubber, which is not completely transparent and is valuable as a decorative article dyed with a small amount of dye, is also effective. Linear φ as line thickness
The reason for limiting to 1.2 mm to φ1.7 mm is that linear φ1.
If it is less than 2 mm, the tensile strength will be weak, and conversely 1.7 mm
This is because a thickness exceeding m is too hard to stretch. As a method of connecting the urethane resin, a method of tying and tying the cords is generally used.
It has been found that joining can be performed very easily by heating to 0 to 250 ° C and joining.

In the present invention, a paint containing a polyimide resin is selected as a coating material for the following reasons. The required properties of the resin used for paints required for decorative products are light reflectivity on the surface, light transmittance,
Light refraction, adhesive strength to materials, strength against impact, hardness that does not easily scratch when contacting hard materials, water resistance, acid / alkali resistance, solvent resistance, UV resistance, and paintability It can be maintained for a long time. Table 1 shows qualitatively general characteristics of resins generally used for coating. Urethane has been found to be superior in terms of light reflectivity, transmittance and refraction as used in contact lenses, etc., but from Table 1, other properties of urethane are less preferable than polyimide resins. I understand. The present inventors, as a coating resin used for bracelets and the like,
In consideration of hardness and environmental reliability, three types of resins, epoxy, polyimide, and nylon, are selected as resins that are not easily scratched, resistant to strong alkalis and strong acids, and do not deteriorate when exposed to strong ultraviolet rays outdoors. When the adhesive strength, acid, alkali, ultraviolet light, and the like are comprehensively examined, Table 1 shows that the polyimide resin is slightly superior.
In addition, in the case of spray-painting by inverting decorative beads or the like, in order to shift to reversing work as soon as possible after one-side spray painting, a paint that becomes tack-free immediately after spraying (a non-sticky paint). This is very important. As a result of consideration by the present inventor to find such a paint,
Dissolve the resin that is the main component in a solvent with a boiling point lower than its melting point, apply the coating at a temperature lower than the boiling point of the solvent, and then leave it at that temperature to reduce the solvent content in a short time. I thought that the free time could be shortened. Therefore, as a result of examining the physical properties of the above three types of resins, the melting point of the resin greatly differs depending on the molecular weight, and it is difficult to specify the melting point (or softening point) because the resin is an aggregate of molecules having different molecular weights. Therefore, the resins that are theoretically easily tack-free are listed in Table 1 above.
It turned out that it was difficult to specify it from the physical properties of the material. However, as a result of repeated series of coating experiments, they have found an important fact that tack-free can be achieved in a short time only when a high-molecular-weight polyimide resin is used. For the above reasons, the present invention uses a paint containing a polyimide resin as a coating material.

[0014]

[Table 1]

The reason for employing the inversion method using an electromagnet as a method for coating the magnet with the polyimide resin is as follows. In general, when coating magnets, the magnets cannot be arranged close to each other due to the attractive force of the magnets. Therefore, it is common to arrange a large number of materials before magnetization in parallel. However, since the object to be coated (magnet beads) is a polyhedron, the object to be coated must be inverted many times in order to paint the entire surface. In the present invention, the magnetic force of the object to be coated is used for the means for reversing the object to be coated. That is, a magnetized material (magnet) is placed on an electromagnet formed by winding an insulated copper wire around an iron block, the upper surface of the electromagnet is used as one pole (for example, N pole), and the lower surface of the magnetized material is used. Is used as the other pole (for example, S pole), spray painting becomes possible due to the attractive force of the magnet, and by changing the direction of the current flowing through the electromagnet, all the magnets can be instantly reversed. As a result, the reversing mechanism can be performed more quickly and more reliably than a reversing mechanism using a mechanical robot or the like, and the entire surface of the magnet can be simply and quickly performed. Therefore, according to this method, by repeating painting and inversion several tens of times with a paint containing a polyimide resin, it is possible to produce decorative magnet beads having excellent aesthetic appearance as a target decorative product in a short time. Become. It goes without saying that a method of instantly reversing a magnetized magnet with an electromagnet can be adopted as a coating method other than the polyimide resin.
