Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is mounted on the wrist of a human body and used as an accessory, and exerts a magnetic therapeutic action by the action of a spherical body with permanent magnets with surface magnetic density of 3000 gauss arranged at both ends of a ring annulus. It concerns lightweight bracelets.

[0002]

[Prior art]

 Conventionally, a bracelet (bangles) has been used as an accessory exclusively worn on the wrist, but recently, focusing on the magnetic therapeutic action of magnetic force, it improves blood circulation at appropriate parts of the human body and relieves stiffness. For the purpose of treatment, a small granular magnetic stone is provided at both ends of an annular ring for contacting the skin surface of the wrist to provide a magnetic therapeutic effect.

[0003]

[Problems to be solved by the device]

 And its structural shape was a substantially C-shaped annular shape, and the gap portion at the open projecting end was expanded, and it was fitted according to the thickness of the wrist and fitted to the wrist. The material of the ring-shaped ring body is iron, brass, stainless steel, etc., which are ordinary steel wires, and when the C-shaped ring ring body is repeatedly expanded when worn on the wrist, it is broken in two from the middle part. Or, there is a drawback that it deforms while being expanded.

[0004] Further, these conventional metal materials have a relatively high specific gravity, which makes them uncomfortable when worn on the wrist, making them unsuitable for sports and the like, and the eating habits of recent Japanese people are similar to those of Westerners. In fact, many people are allergic to metal, and not only stainless steel and brass, which contain nickel metal as a material, but also gold products of 18K gold, the number of people who damage the skin is increasing.

Therefore, the present invention is intended to provide a lightweight bracelet developed to solve these problems.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the lightweight bracelet according to the present invention uses pure titanium or titanium alloy as the material of the substantially C-shaped ring ring body, compared to conventional materials such as stainless steel, brass and iron. By setting the specific gravity to half or less, the most suitable product as an actual sports ring is obtained.

The shape of the lightweight bracelet is a substantially C-shaped ring ring body, and can be any shape that fits comfortably when worn on the wrist, and its forming material is stainless steel, brass, iron or the like. The main component is titanium or titanium alloy, which is about half the weight of the specific gravity, and the substantially C-shaped ring annulus is made of steel wire or stranded wire.

Spherical bodies are attached to both ends of the substantially C-shaped ring body so as to face each other, and the ring body can be slightly deformed so that the gap between the facing spherical bodies can be expanded or contracted. And the spherical body is attached so as to protrude in the central radial direction of the ring annulus from the inner circumference of the ring annulus of the attachment base.

Then, a 3000 Gauss permanent magnet is embedded in the bottom of the insertion hole of the ring annulus in the spherical body to magnetize the spherical body to generate surface magnetic flux.

The substantially C-shaped ring annulus is formed of a titanium stranded wire made of a titanium or titanium alloy element wire having a required thickness, and is deformed by expansion for attachment to a wrist or the like. It has the ability to restore the original shape before deformation due to the elastic force of the stranded wire.

[0011]

[Action]

 When the lightweight bracelet according to the present invention is attached to the wrist, the magnetic characteristics of the strong permanent magnet of 3000 gauss embedded in the spherical body exert a magnetic therapeutic effect and promote blood circulation. As a result, it stimulates deep cells in local areas such as the elbows, shoulders, and knees, enables a magnetic therapeutic effect, adjusts the balance of the body, and relieves stiff shoulders and local pain.

Since the material of the substantially C-shaped ring annulus is made of stranded wire made of titanium or titanium alloy, it is necessary to forcibly widen the distance between the spherical bodies attached to both ends of the ring annulus. Even if it is attached to the neck, it restores the original shape of the substantially C-shaped ring body before deformation, and fits with the wrist that is the attachment site.

Further, since the substantially C-shaped ring annulus and spherical body are made of pure titanium or titanium alloy, their specific gravity is half or less compared to the conventional products of this kind, and it is light when used and is easy to use on the wrist. No discomfort when worn.

Furthermore, since pure titanium or titanium alloy is used as the material, there is no risk of rusting on the parts that come into contact with the wrist or the skin. In particular, in this invention, the surface of the material is specially polished and Since the entire surface is ion-plated, the surface is hard and can be used continuously for a long period of time even when sweating, bathing, washing the face, etc., and skin irritation or rash due to long-term use It is a lightweight bracelet that is suitable as a magnetic therapy device without worrying about wear.

In addition, a spherical body having a built-in permanent magnet is arranged at each of opposite portions of both ends of the substantially C-shaped ring body, and the substantially C-shaped ring is arranged to expand or contract the interval between these spherical bodies. The annulus is plastically deformable with elasticity that restores it to its original shape depending on the characteristics of its forming material, and both of these spherical bodies are larger than the inner circumference of the ring annulus of the mounting base, and the center diameter of the annulus Since it projects and swells in the direction, the spherical body makes good contact with the surface of the skin when worn on the wrist, and there is no pressure from the spherical body.

Further, since the permanent magnet contained in the spherical body for the purpose of magnetic therapy is embedded in the bottom of the insertion hole of the ring ring body, it is possible to replace the permanent magnet with a magnetic force as needed. Since the body itself has magnetic properties, it is not necessary to provide a fixing means such as adhesion or caulking to fix the permanent magnet.

【Example】

 An embodiment of a lightweight bracelet according to the present invention will be described below with reference to the drawings. The lightweight bracelet 1 shown in FIG. 1 is to be worn on the wrist of an arm of a body and comprises a ring body 2 having a substantially C shape and spherical bodies 3 provided at both ends of the ring body 2. It has.

As a means for fixing the ring body 2 and the spherical body 3, an insertion hole 4 of the ring body 2 is formed toward the center of the spherical body 3. Insert both ends of the ring annulus 2 and use the main components for welding with weld metal, hard brazing with hard solder such as silver braze, gold braze, silver braze or brass braze, and synthetic resin such as epoxide resin and phenol resin. Adhesion, screwing, mechanical pressure welding, press fitting, etc.

FIG. 1 shows an example in which the wire is made of pure titanium or titanium alloy ordinary wire.

As a material for forming the ring-shaped body 2 of the substantially C shape, those shown in FIGS. 1 and 3 use pure titanium or a titanium alloy stranded wire, and if necessary, use two or three wires. Five, seven, and nineteen twists are appropriately selected, and the ring annulus 2 shown in FIG. 5 is formed by crushing or grinding the cross section into a semi-cylindrical shape.

Each of the substantially C-shaped ring annuli 2 shown in the above-mentioned examples has a high yield point, is tough, and withstands fatigue due to repeated bending stress and torsional stress, and is left unattended during long-term use. Since it is necessary to have the durability to maintain the original shape, it is manufactured by hot or cold forming, quenching, tempering, etc., if necessary. Therefore, when the distance between the opposing spherical bodies 3 arranged at both ends of the substantially C-shaped ring annulus 2 is expanded, it has elasticity such that it restores to its original shape, and in the original state in which it can expand and contract. It is formed so that it can retain its shape.

A 3000 Gauss permanent magnet 5 is embedded in the bottom of the insertion hole 4 at both ends of the ring body 2 formed in the spherical body 3 (in the direction of the center of the spherical body 3), and the spherical body 3 The magnetic therapeutic effect is exerted by the magnetic attraction force of. Further, although the surface magnetic flux density of the permanent magnet 5 is a ferromagnetic material of 3000 gauss in the embodiment, this magnetic flux density is not limited and may be another value.

Further, the spherical body 3 is disposed so as to project in the central radial direction of the ring annulus 2 from the inner circumference of the ring annulus 2 of the attachment base thereof, and is attached to the surface of the skin when worn on the wrist. It is formed so that it can be in close contact.

Further, the entire surface of the ring-shaped body 2 and the spherical body 3 having the substantially C shape is subjected to ion plating finish with ion coating to make the surface hard, and damages and peeling of the surface can be prevented. .

In addition to the ion plating finish, a satina finish may be used.

[0026]

[Effect of device]

 As described above, the lightweight bracelet according to the present invention has a significantly smaller specific gravity and is lighter than the conventional magnetic bracelet of this kind, so that it does not feel uncomfortable when worn on the wrist, and is particularly suitable for sports. It is the best one.

Since pure titanium or titanium alloy is used as a material for forming the ring body of substantially C-shape, in addition to its light weight, its entire surface is ion-plated, so that sweating is prevented. There is no hindrance such as rusting due to bathing or bathing, and the original shape can be maintained at all times because the twisted wire material of titanium or titanium alloy is used as the material, and the spherical body between the spherical bodies when worn on the wrist. It is easy to expand and contract, and can be expected as a lightweight bracelet with a magnetic therapeutic effect.
