JPH11103915A - Magnetic bracelet without using through cord and metallic connector - Google Patents

Abstract

PROBLEM TO BE SOLVED: To unnecessitate a through cord and a metallic connector, to separate balls from each other by putting a ferromagnetic magnet such as a neodymium magnet in a nonmagnetic matter whose force sucked to a magnet is weak and to enrich variety by separating the balls from each other and combining various balls to vary the length of the whole of them. SOLUTION: The structure of the ball is prepared by putting the ferromagnetic magnet 2 in the form as a cylinder in a nonmagnetic matter 1. At the time of equalize the radius of curvature of the surface of the magnet 2 with the radius of curvature of the matter 1, the whole balls are made spherical to arrange the balls neatly in a ring-form. The balls are not detached easily from one another even at the time of swinging around a hand once they are attracted the operation of the magnet 2. At the time of providing a curvature for the surface of a magnet to bring the ball nearly into point contact with each other, the balls can simply be detached by the multiplier effect of the reduction of magnetic force line made by putting a finger into mutual balls in a direction vertical to the attracting direction of the mutual balls and the operation of a lever while having strong attracting force in the direction of magnetic lines.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracelet having balls as constituent elements, wherein the balls are connected by using the force of a magnet without using a string or a connecting metal.

[0002]

2. Description of the Related Art A conventional bracelet having balls as components is made into a product by making holes in each ball and using a connecting bracket or a string. Some necklaces used magnets for some balls, but the purpose was for health effects and partial connection, and strings and the like were used.
6821). There was an accessory that covered about half of the ball with a magnetic substance and attached / detached the accessory base and the ball using magnets or screws (Japanese Patent Laid-Open No. 8-38224). No bracelet has a structure that does not come off easily and can be easily removed with a finger.

[0003]

A conventional bracelet having a ball as a component has the following disadvantages. The position of the ball was fixed without being removed due to the presence of the through string and the connecting bracket, and various combinations of balls (color, shape, size, etc.) were impossible and lacked variety. The present invention has been made to overcome these disadvantages.

[0004]

A bracelet according to the present invention has solved the above-mentioned problems and has the following structure. As shown in FIG. 1, the magnetic force is used as the attracting force between the balls. A magnet having a strong magnetic force (hereinafter abbreviated as a strong magnetic force magnet) 2 such as a neodymium magnet is included in a material (hereinafter, abbreviated as a non-magnetic material) 1 having a weak force to attract a magnet as a structure of a ball serving as a component of a bracelet. The balls are put together and used to form a bracelet by connecting the balls one after another using magnetic force.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One of the bracelets constituting the bracelet has an N pole and the other has an S pole. For this reason, if the N pole (or S pole) of one ball and the S pole (N pole) of another ball are brought close to each other, the balls will naturally attract each other and be attracted to each other. Even if the N-pole (or S-pole) of one ball is brought closer to the N-pole (S-pole) of another ball, the balls repel each other and rotate naturally, and the balls are easily attracted to each other. Repeat this to make a bracelet into a ring.

【Example】

Embodiment 1 Embodiment 1 will be described with reference to FIG. It is necessary to reduce the number and density of lines of magnetic force spreading around the bracelet in order not to attract various magnetic substances around the bracelet other than the balls. Further, a strong magnet is used to connect the balls without using a string or a connecting metal. For this purpose, as shown in FIG. 1, a cylindrical strong magnetic magnet 2 is formed in a non-magnetic substance 1 as a ball structure. The radius of curvature of the surface of the magnet 2 is non-magnetic material 1
When the radius of curvature is made equal to the radius of the ball, the ball becomes spherical as a whole, and the balls can be arranged neatly in a ring shape. Once attracted by the action of a strong magnetic magnet, Tamaki cannot easily come off even if he shakes his hand. This is because the balls have a strong attraction force in the attracting direction of the balls, that is, in the direction of the lines of magnetic force. Here, when the surfaces of the magnets have a curvature and bring the balls into almost point contact with each other, they have a strong attraction force in the direction of the line of magnetic force, but in a direction perpendicular to the direction of the attracting balls (the direction perpendicular to the line of magnetic force). Can be easily separated by the reduction of the magnetic field lines by putting the fingers into the balls and the synergistic effect with the leverage action. If the whole ball is colored after the magnet 2 is inserted into the non-magnetic substance 1, or if the magnet 2 is put inside the non-magnetic substance 1 and the lid is closed, the magnet 2 is not seen from the outside and the aesthetic characteristics are increased.

Second Embodiment A second embodiment will be described with reference to FIG. As shown in FIG. 2A, a disc-shaped depression 3 is formed in a part of the surface of the non-magnetic substance 1, and a disc-shaped depression 3 is formed on the opposite side, and a disc-shaped magnet is formed in each of the depressions. A magnetic bracelet composed of a ball to which No. 4 is bonded. If the radius of curvature on the surface side of the disc-shaped magnet 4 is made equal to the radius of curvature of the non-magnetic substance 1, the balls are neatly arranged in a ring-like manner as in the first embodiment, and attachment and detachment become easy. The poles of the magnets on the front side may be opposite or the same for the two magnets. Also, as shown in FIG. 2B, when the centers of the two recesses 3 are directed in the direction of attracting the balls, the balls are connected more smoothly.

Third Embodiment A third embodiment will be described with reference to FIG. As shown in FIG. 3A, several of the balls constituting the bracelet use magnet balls 5 which are entirely magnets. On the other hand, as shown in FIG. 3B, an alphabet or a heart-shaped ornament 6 is made of a magnetic substance 7 and a non-magnetic substance 8. The magnetic substance 7 has a depression 9 having the same radius of curvature as the magnet ball 5, and the magnet ball 5 is attracted into this depression. These ornaments have a one-point effect on magnetic bracelets.

Embodiment 4 Embodiment 4 will be described with reference to FIG. FIG. 4A shows an example of the bracelet of Example 1 in which the colors of the balls are variously combined.
Shown in FIG. 4B shows an example of the size of the ball, and FIG. 4C shows an example of the bracelet in which the shape of the ball is variously combined. Further, these three elements can be combined.

[0010]

According to the present invention, a magnetic bracelet having a non-magnetic material on the outside and a ball having a strong magnet inserted therein as a component does not require a through string or a connecting bracket. In addition, the structure is inexpensive because the structure is not complicated. The balls are firmly attracted due to the strong magnetic force of the magnet. On the other hand, if the magnets have curvature and the balls come into almost point contact with each other, the attracting direction of the balls is perpendicular to the direction of the magnets (perpendicular to the line of magnetic force). Direction), the fingers can be easily separated from each other by the reduction of the magnetic field lines by putting the finger into the balls and the synergistic effect with the leverage action. In addition, since the present invention does not use a string or a connecting bracket, in the present invention, each individual can combine balls of various colors, shapes, and sizes to change the overall length, thereby making it possible to produce a very wide variety of bracelets. One-point effects can also be achieved by adhering alphabets and heart-shaped ornaments to a part of the ball, and a fun learning effect can be expected when used by infants. And endless bracelets are endlessly different. It's a new bracelet style. And it becomes a unique thing that individual personality emerged.
