Description

[Technical Field]

[0001] The present invention relates to a magnetic therapeutic device such as a magnetic bracelet or a magnetic necklace. [Background technology]

[0002] Conventionally, magnetic treatment devices using permanent magnets include the magnetic bracelets described in Patent Document 1 (JP Patent Publication No. 11-103915) and Patent Document 2 (Utility Model Registration No. 3042173). These magnetic bracelets consist of multiple magnetic links connected in a rosary shape, and the magnetic lines of force emitted from the magnetic links promote blood circulation and relax muscles in the area where the bracelet is worn.

[0003] When connecting magnet pieces in a rosary shape, various connection configurations can be adopted, as shown in Figures 4A to 4C, taking into consideration the magnetic treatment effect, design, etc. Figures 4A and 4C show an arrangement that combines multiple plate-shaped magnet pieces 11 and ball-shaped magnet pieces 12, while Figure 4B shows an arrangement that uses three independent rectangular column-shaped magnet pieces 11' instead of the plate-shaped magnet pieces 11. The magnet pieces 11, 11', and 12 can be connected in a rosary shape by, for example, three stainless steel chains 13.

[0004] Here, the strength of the magnetic lines of force of magnet pieces 11, 11', 12 can be, for example, 170 mT (millitesla) for one of magnet pieces 11, 11', and a weaker 100 mT for the other magnet piece 12. By varying the strength of the magnetic lines of force in this way, it is expected that the effect of magnetic therapy will be enhanced. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-103915 [Patent Document 2] Utility Model Registration No. 3042173 Summary of the Invention [Problem to be solved by the invention]

[0006] When magnet pieces with different magnetic field strengths are arranged as shown in Figures 4A-4C, the orientation of the magnet pieces changes due to the magnetic force between them. That is, when four or three ball-shaped magnet pieces 12 with weak magnetic field strength are arranged between left and right magnet pieces 11, 11' with strong magnetic field strength, as shown in Figures 4A(a), 4B(a), and 4C(a), the ball-shaped magnet pieces 12 adjacent to the left and right magnet pieces 11, 11' will be oriented south or north due to the influence of the magnet pieces 11, 11'.

[0007] In contrast, the middle ball-shaped magnet pieces 12 sandwiched between the ball-shaped magnet pieces 12 on both sides react magnetically with the magnet pieces 12 above and below (in the adjacent rows) as shown in Figures 4A(b), 4B(b), and 4C(b), and rotate (about 90°) around the chain 13, changing their orientation. For this reason, when viewed through the magnetic viewer sheet, it can be seen that the orientation of the magnetic field lines is disturbed, as shown in Figure 3(b), and this disturbance in the orientation of the magnetic field lines presents the problem of reducing the effectiveness of magnetic therapy.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a magnetic therapy device that can suppress disturbance in the orientation of magnetic lines of force. [Means for solving the problem]

[0009] To achieve the above-mentioned object, the magnetic therapy device of the present invention is a band-shaped magnetic therapy device in which a plurality of magnet pieces are connected in multiple rows in a rosary shape, and the plurality of magnet pieces include a first magnet piece with a high magnetic line strength and a second magnet piece with a low magnetic line strength, and one or two second magnet pieces are arranged between the first magnet pieces in the rosary-shaped connection direction of each row, and the first magnet pieces and the second magnet pieces are adjacent to each other in each of the multiple rows in the width direction of the band. [Effects of the Invention]

[0010] The magnetic therapy device of the present invention can suppress the disturbance of the orientation of the magnetic lines of force. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] A magnetic bracelet 10 as a magnetic therapy device according to an embodiment of the present invention will be described below with reference to the drawings. Figure 1(a) is a plan view of the magnetic bracelet 10 as seen from the outside (front side), (b) is a side view, and (c) is a cross-sectional view.

[0013] The bracelet 10 has a number of relatively large, rectangular, plate-like magnet links 11, a number of relatively small, ball-shaped magnet links 12, and three stainless steel chains 13 as cord-like bodies inserted into holes formed through the magnet links 11, 12. The multiple magnet links 11, 12 are connected in a bead-like or belt-like manner by the three chains 13. The chains 13 can be replaced with wire, fiber string, elastic string, or even a rigid C-shaped ring.

[0014] In addition, a ring-shaped elastic spacer made of silicone resin or the like can be inserted between the magnets 11 and 12 to hide the chain 13. This elastic spacer can improve the appearance of the bracelet 10 and also prevent the magnets 11 and 12 from rattling or being damaged.

[0015] The magnet blocks 11 and 12 can be made of a magnetic material, preferably a hard magnetic material, such as electromagnetic stainless steel, silicon iron, neodymium magnets, rare earth magnets such as samarium-cobalt magnets, ferrite magnets, and alnico magnets.

[0016] Here, the large magnet piece 11 is the first magnet piece 11, which has a high magnetic field strength of, for example, 170 mT. The small, ball-shaped magnet piece 12 is the second magnet piece 12, which has a low magnetic field strength of, for example, 100 mT. The shapes of the magnet pieces 11 and 12 are not limited to those shown in the figure, but can be changed to any shape taking into consideration design and the like. The magnetic field strength can also be changed to any size within the JIS standard range (35 to 200 mT) for home permanent magnet magnetic therapy devices.

[0017] A metal receiving bracket 14 and a metal hook 15 are connected to both longitudinal ends of the bracelet 10. After wearing the magnetic bracelet 10 on the wrist, the metal hook 15 can be engaged with the metal receiving bracket 14 to close the magnetic bracelet 10 into a ring shape. Note that the portions of the metal receiving bracket 14 and the metal hook 15 adjacent to the ball-shaped magnet link 12 can also be made of magnets, similar to the plate-shaped magnet link 11, to enhance the magnetic therapy effect.

[0018] In this embodiment, the ball-shaped magnet pieces 12 are held in three rows between the plate-shaped magnet pieces 11. The ball-shaped magnet pieces 12 are each rotatable around the chain 13.

[0019] This can prevent twisting of the chain 13. Note that, taking into consideration design and the like, the ball-shaped magnet pieces 12 can be arranged in two rows as shown in Figures 2D and 2E, or in four or more rows.

[0020] The plate-shaped magnet pieces 11 and ball-shaped magnet pieces 12 can be magnetized in the radial direction (thickness direction of the band-shaped bracelet) around the chain 13 as shown in Figures 2A-2F. The magnetization process for the magnet pieces 11 and 12 can be carried out in a separate process before the chain 13 is inserted, or can be carried out in the finished bracelet state after the chain 13 has been inserted.

[0021] The plate-shaped magnet piece 11 is magnetized in the direction of the paper in Fig. 2A (the radial direction in Fig. 2B, the thickness direction of the band-shaped bracelet) so that the magnetic poles alternate as N, S, N.... When viewed from the outside, the magnetic poles of the plate-shaped magnet piece 11 are N, S, N... from the left, but when viewed from the inside, they are S, N, S... as shown in Fig. 2B.

[0022] On the other hand, because the ball-shaped magnet piece 12 is adjacent to the plate-shaped magnet piece 11, which has stronger magnetic field strength, it is more strongly attracted to the magnetic pole of the adjacent plate-shaped magnet piece 11. For this reason, the ball-shaped magnet piece 12 adjacent to the north pole of the plate-shaped magnet piece 11 becomes (rotates) a south pole, and the ball-shaped magnet piece 12 adjacent to the south pole of the plate-shaped magnet piece 11 becomes (rotates) a north pole. Therefore, arc-shaped magnetic field lines are formed between the plate-shaped magnet piece 11 and the ball-shaped magnet piece 12 in the circumferential direction of the wrist, as shown in Figure 2B.

[0023] As a result, the inner arc-shaped magnetic field lines ML penetrate in the circumferential direction around the wrist wearing the bracelet 10. This can promote blood circulation around the wrist and relax the muscles.

[0024] Figure 3(a) shows a portion of the bracelet 10 of this embodiment as viewed through a magnetic viewer sheet. From this figure, it can be seen that strong magnetic lines of force are formed between the plate-shaped magnet piece 11 and the ball-shaped magnet piece 12, extending in the left-right direction.

[0025] In contrast, in the conventional arrangement of the magnet links 11' and 12 of the bracelet 10 shown in Figure 4B(b), for example, the magnetic field lines between the plate-shaped magnet link 11 and the ball-shaped magnet link 12 are weakly and irregularly disturbed, as shown in Figure 3(b). Such irregularly disturbed magnetic field lines may reduce the effectiveness of magnetic therapy.

[0026] 2C to 2F are plan views showing the magnetized state of magnet links 11, 11', and 12 of a modified bracelet 10. Fig. 2C shows an example in which three independent rectangular magnet links 11' are used instead of the plate-shaped rectangular magnet link 11.

[0027] Because the adjacent magnet pieces 11' are prismatic, they interfere with each other in the direction of rotation about the chain 13 and cannot rotate freely. This maintains the magnetized state shown in Figure 2C. Therefore, in the case of Figure 2C, arc-shaped magnetic lines of force are formed between magnet piece 11' and magnet piece 12, similar to those in Figure 2B.

[0028] Figure 2D shows an example in which two ball-shaped magnet pieces 12 are arranged in two rows, two each, between plate-shaped rectangular magnet pieces 11. The two rows of ball-shaped magnet pieces 12 react magnetically with each other and tend to rotate around the chain 13 from the state shown in Figure 2D, but the rotation is suppressed by the magnetic reaction with the magnet pieces 11, which have stronger magnetic field strength. For this reason, arc-shaped magnetic field lines similar to those shown in Figure 2B are formed between the magnet pieces 11 and 12 in the case of Figure 2D as well.

[0029] Figure 2E shows an example in which ball-shaped magnet pieces 12 are arranged in two rows, one between each of the plate-shaped rectangular magnet pieces 11. The two rows of ball-shaped magnet pieces 12 react magnetically with each other and tend to rotate around the chain 13 from the state shown in Figure 2E, but the rotation is suppressed by the magnetic reaction with the magnet pieces 11, which have stronger magnetic field strength. For this reason, arc-shaped magnetic field lines similar to those shown in Figure 2B are formed between the magnet pieces 11 and 12 in the case of Figure 2E as well.

[0030] Figure 2F shows an example in which ball-shaped magnet pieces 12 are arranged in three rows, one between each of the plate-shaped rectangular magnet pieces 11. The three rows of ball-shaped magnet pieces 12 react magnetically with each other and tend to rotate around the chain 13 from the state shown in Figure 2F, but the rotation is suppressed by the magnetic reaction with the magnet pieces 11, which have stronger magnetic field strength. For this reason, arc-shaped magnetic field lines similar to those shown in Figure 2B are formed between the magnet pieces 11 and 12 in the case of Figure 2F as well.

[0031] While the present invention has been specifically described above based on the embodiments, it goes without saying that the present invention is not limited to the above embodiments and can be modified in various ways within the scope of the technical concept described in the claims. For example, while the above embodiments illustrate a magnetic bracelet 10 as an example of a magnetic therapy device, the magnetic therapy device of the present invention is not limited to the magnetic bracelet 10 and can also be applied to magnetic necklaces, etc. Furthermore, while the above embodiments illustrate a case in which the ball-shaped magnet piece 12 is rotatable around the chain 13, it may also be fixed to the chain 13 in a non-rotatable manner after being magnetized as shown in Figure 2A, for example.
