Hereinafter, an embodiment of a magnetic therapy apparatus 10 according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view (A) and a front view (B) of a magnetic therapy device in the present embodiment.
The magnetic therapy device 10 according to this embodiment includes a left panel unit 20 including a left panel body 22, a central panel unit 30 including a central panel body 32, and a right panel unit 40 including a right panel body 42. As shown in FIG. 1, the magnetic treatment device 10 has a left panel portion 20 and a right panel portion 40 rotatably connected to a central panel portion 30 via a connecting shaft 50 that is a connecting portion. Thus, in the magnetic therapy device 10 constituted by three panel bodies, a power cord 60 for supplying power and a connection cord 70 electrically connected to an operating device (not shown) are connected to the right panel body by a connector (not shown). 42 is detachably connected. The power cord 60 and the connection cord 70 can be connected to the central panel portion 30 or the left panel portion 20.

  In the present embodiment, the left panel unit 20, the central panel unit 30, and the right panel unit 40 are each composed of one panel body, but the first panel body, the second panel body, the third panel body, You may be comprised by four or more panel bodies made into 4 panel body, 5th panel body .... In this case, the panel bodies constituting each panel unit may be connected to each other via the connecting shaft 50 so as to be rotatable.

  The left panel unit 20 and the right panel unit 40 will be described. In the present embodiment, the left panel portion 20 and the right panel portion 40 basically have the same structure, and therefore only the left panel portion 20 will be described here. The configurations described as the first to 2X (X is a natural number or a combination of a natural number and a character) in each configuration of the left panel unit 20 are the second to 4X (X is a natural number or a combination of a natural number and a character). It can be replaced with a combination of natural numbers and letters.

  As shown in FIG. 1A, the left panel portion 20 has a left panel body 22 that is formed in a substantially U shape in plan view, and a spherical projection on the upper surface side of the left panel body 22. A shaped portion 23 is provided. The protrusion 23 can obtain acupressure effect when a part of the user's body is pressed against the magnetic therapy device 10. Such protrusions 23 are arranged in a plurality of rows at necessary positions in the vicinity of the left and right ends of the left panel body 22. In the present embodiment, the heater 24 is embedded in a position below the protruding portion 23 on the central panel portion 30 side. The heater 24 is for warming the surface of the magnetic therapy device 10, and is particularly for providing a good feeling in winter. The protrusion 23 is also advantageous in that it prevents low-temperature burns due to long-term contact with the heater 24 embedded portion. The power supply to the heater 24 is controlled by a current control unit (not shown) to turn on and off the power supply.

  In addition, an electromagnet 25 and a vibrator 26 are embedded in the central portion of the left panel body 22 in the plane. The electromagnet 25 is embedded at two locations (planar positions on which concentric patterns are formed) that are arranged so as to sandwich the vibrator 26 from above and below in FIG. Further, the vibrator 26 is disposed in a state where one end of the cylindrical body 26A is in contact with the vibrator. Since the other end portion of the cylindrical body 26A protrudes from the upper surface of the left panel body 22, if a part of the user's body is brought into contact with the cylindrical body 26A, vibration from the vibrator 26 is caused to vibrate. It is suitably given to a part of the user's body through the massage, and a massage effect can be obtained. In addition, the vibration caused by the vibrator 26 reaches a set time when the magnetic treatment device 10 is used by a predetermined time after the magnetic supply by the magnetic treatment device 10 is started, a required time interval at the time of magnetic supply by the magnetic treatment device 10, or a timer setting function. It can also occur at any or all of the previous predetermined times. The vibration generated by the vibrator 26 can be used as a means for transmitting the operating state of the magnetic therapy device 10 to the user.

A connection hole 28 for mounting the connection shaft 50 is provided on the side surface of the two protruding portions 20A on the right side of the left panel portion 20. The connection part in this embodiment is comprised by the connection shaft 50 and the connection hole 28 (connection hole 38).
On / off operation and output of the power supply to the electromagnet 25 and the vibrator 26 are controlled by the current control unit 80.

Next, the center panel part 30 is demonstrated. As shown in FIG. 1A, the central panel 30 has a central panel body 32 having a substantially cross shape in plan view, and a spherical projection 33 on the upper surface side of the central panel 32. Is arranged. The protrusions 33 are arranged in a plurality of rows at necessary positions in the vicinity of the left and right ends of the central panel body 32. An electromagnet 35 and a vibrator 36 are embedded in the center position of the center panel body 32 in the plane. The electromagnet 35 is embedded in two places (concentric pattern portions) in an arrangement in which the vibrator 36 is sandwiched from above and below in FIG. The vibrator 36 is disposed in a state where one end of the cylindrical body 36A is in contact with the vibrator. On the upper surface of the central panel body 32, the other end of the cylindrical body 36A projects. On the side surfaces of the projecting portions 30A at the two left and right side surfaces of the central panel portion 30, there are provided connection holes 38 through which the connection shafts 50 as connection portions are inserted.
As with the left panel unit 20, on / off operation and output of the electric power supply to the electromagnet 35 and the vibrator 36 disposed in the central panel unit 30 are controlled by the current control unit 80.

A magnetic pole switching mechanism that switches the magnetic poles of the electromagnets 25, 35, and 45 built in the panels 20, 30, and 40 according to the connection angle of the panels 20, 30, and 40 will be described.
Here, only the first detection means provided in the left panel portion 20 will be described in detail, but the second detection means provided in the right panel portion 40 has the same configuration as the first detection means. Can be adopted. 2 to 4 are a perspective view (A) showing a schematic structure of the first detection means of the magnetic therapy apparatus in the present embodiment and an operation explanatory diagram (B) corresponding to the perspective view.
At least one of the protruding portions 20A of the left panel portion 20 has a first detection means, an LED 29A as a light irradiation means as a first signal transmission means, and a light detection as a first signal detection means. The phototransistor 29B as a means is fixed in a state where it is mounted on the substrate 29C with a required interval.

The phototransistor 29B is electrically connected to a microcomputer and a current control unit having a magnetic pole switching operation control program, and light reception amount information is transmitted to the current control unit constantly or at a required time interval. In addition, a protruding piece 29 </ b> D that is a first shielding member is formed at the distal end portion of the connecting shaft 50. The protruding piece 29D portion is formed or covered with a light-impermeable material. In the present embodiment, the connecting shaft 50 and the protruding piece 29D are integrally formed, but the connecting shaft 50 and the protruding piece 29D can be formed separately and assembled together. The projecting piece 29D formed in this way rotates between the LED 29A and the phototransistor 29B by rotating together with the connecting shaft 50 as the left panel unit 20 and the right panel unit 40 rotate with respect to the central panel unit 30. It is provided so that it can move forward and backward.
As shown in FIG. 2, the protruding piece 29D is not separated from the LED 29A and the phototransistor 29B in the range from the state in which the left panel portion 20 is coplanar with the central panel portion 30 to the required angle. It is located in the place. In this state, the phototransistor 29B detects a received light amount of 100% with respect to the maximum received light amount.

  When the left panel portion 20 is rotated with respect to the central panel portion 30, the LED 29A and the phototransistor 29B are rotated together with the left panel portion 20, and as shown in FIG. 3, a protruding piece is provided between the LED 29A and the phototransistor 29B. A part of 29D will enter. Since the protruding piece 29D is made of a light-impermeable material, the protruding piece 29D covers a part of the light receiving area of the phototransistor 29B (the light irradiation portion of the LED 29A). The amount of received light is reduced compared to the state (maximum amount of received light) before being rotated with respect to the central panel unit 30. The phototransistor 29B can digitize the actual amount of received light as a percentage of the maximum amount of received light, and the numerical data of the amount of received light is transmitted to the current control unit.

In the magnetic pole switching operation control program of the current control unit, a threshold for the numerical data of the received light amount transmitted from the phototransistor 29B is set in advance. It is more convenient if the threshold value set in this magnetic pole switching operation control program is set to be changeable by an external input means or the like.
When the current control unit confirms that the numerical data of the amount of received light received from the phototransistor 29B is below the threshold value, the current control unit determines that the left panel unit 20 has been rotated by a predetermined angle or more with respect to the central panel unit 30. ing. When the left panel 20 further rotates with respect to the center panel 30 and the rotation angle of the left panel 20 with respect to the center panel 30 is 90 degrees, as shown in FIG. The entire light receiving surface of the phototransistor 29B is covered (the entire light irradiation surface of the LED 29A is covered). That is, in this state, the numerical data of the received light amount transmitted from the phototransistor 29B to the current control unit is 0%.

The current control unit includes numerical value data of the received light amount that is a received light amount signal transmitted from the phototransistor 29B that is a part of the first signal detection unit fixed in the left panel unit 20, and the right panel unit 40. In combination with the numerical data of the received light amount transmitted from the fixed phototransistor (not shown), the electromagnets 25, 35, and 45 incorporated in the left panel unit 20, the central panel unit 30, and the right panel unit 40, respectively. It also functions as switch means for appropriately switching the power supply state (current direction).
Specifically, when the numerical data of the received light amount transmitted from the phototransistor 29B (the right panel portion is not shown) of the left panel portion 20 and the right panel portion 40 are both in the range of 100% to 50% ( When the positional relationship among the LED 29A, the phototransistor 29B, and the projecting piece 29D is within the range shown in FIGS. 2 to 3, the current control unit has the electromagnets 25, 35, A first state is provided in which current is supplied to the electromagnets 25, 35, and 45 so that all the upper surfaces of the 45 become N poles.

  Further, when only the numerical data of the amount of light received from the phototransistor of either the left panel unit 20 or the right panel unit 40 (here, the phototransistor 29B of the left panel unit 20) is less than 50% (LED 29A When the positional relationship between the phototransistor 29B and the projecting piece 29D is slightly close to the state shown in FIG. 4 from the state shown in FIG. 3), the current control unit as shown in FIG. The direction of the current supplied to the electromagnet 25 of the left panel portion 20 is opposite to the initial state (the state before the left panel portion 20 is rotated), and the surface on the side of the central panel portion 30 and the right panel portion 40 is the S pole. A second state is provided.

  Furthermore, when both the numerical data of the received light amount transmitted from the phototransistor 29B (the right panel unit is not shown) of the left panel unit 20 and the right panel unit 40 are less than 50%, the current control unit As shown in FIG. 8, the direction of the current supplied to the electromagnet 25 of the left panel portion 20 is reversed from the initial state (the state before the left panel portion 20 is rotated), and the electromagnet 35 of the central panel portion 30 is moved. Is provided, and the third state is maintained in which the direction of the supply current to the electromagnet 45 of the right panel unit 40 is maintained in the initial state (the surface facing the left panel unit 20 is the N pole). To do.

In the first state, as shown in FIGS. 5 and 6, the magnetic therapy device 10 has a substantially flat surface, and the magnetic poles on each surface can be made the same. Can act.
In the second state, when the magnetic therapy device 10 is used in a substantially L shape as shown in FIG. 7, the lines of magnetic force from the central panel 30 and the right panel 40 are concentrated on the left panel 20. Therefore, a stronger magnetic force can be applied as compared with the first state. When the conventional magnetic therapy device is in the state shown in FIG. 7, the magnetic poles of the left panel portion 20 and the magnetic poles of the central panel portion 30 and the right panel portion 40 are repelled from each other. The magnetic force could not be efficiently applied to the part to be applied. For this reason, it is understood that the magnetic therapy device 10 in the present embodiment is extremely convenient.

  In the third state, as shown in FIG. 8, when the magnetic therapy device 10 is used in a U shape, a magnetic field emitted from the right panel unit 40 forms a magnetic field that flows toward the left panel unit 20. It will be. Further, since no magnetic force is released from the electromagnet 35 of the central panel portion 30, the magnetic force released from the N pole of the right panel portion 40 flows directly into the S pole of the left panel portion 20, so that the user If the part where the magnetism is to be applied is arranged at the position of the central panel portion 30, magnetism can be concentrated. When the conventional magnetic therapy device is in the state shown in FIG. 8, the magnetism from the left panel unit 20 and the magnetism from the right panel unit 40 are repelled from each other by the magnetism from the central panel unit 30. The magnetic force could not be efficiently applied to the person. Also in this respect, it can be appreciated that the magnetic therapy device 10 in the present embodiment is extremely easy to use.

  FIG. 9 is a block diagram showing a schematic structure of the magnetic therapy device according to the present embodiment. As shown in FIG. 9, a current control unit 80 is connected to the electromagnets 25, 35, and 45 built in each of the left panel unit 20, the central panel unit 30, and the right panel unit 40. The current controller 80 controls the amount of current to be supplied to the electromagnets 25, 35, 45, thereby making a difference in the strength (magnetic flux density) of the magnetic force generated by each electromagnet 25, 35, 45. By changing the strength (magnetic density) of the magnetic force applied to the body from 25, 35, and 45, the body is prevented from becoming accustomed to the magnetic field, thereby enabling effective magnetic therapy.

As the intensity pattern of the amount of current supplied from the current control unit 80 to the electromagnets 25, 35, 45, for example, the intensity pattern of the supply current as shown in FIGS. 10 to 12 can be adopted. Here, the horizontal axis of each graph shown in FIGS. 10 to 12 is a time axis, and the vertical axis represents the magnetic flux density generated by the electromagnet (that is, the amount of current supplied to the electromagnet).
The electromagnets 25, 35, and 45 generate a magnetic flux density according to the supplied current amount. The electromagnets 25, 35, and 45 in the present embodiment have the same performance.

First, the strength pattern of the supply current shown in FIG. 10 will be described.
The intensity pattern of the magnetic flux density generated by the electromagnets 25, 35, and 45 by the current supplied from the current controller 80 illustrated in FIG. 10 is a random magnetic flux density within the range of the maximum magnetic flux density and the minimum magnetic flux density. It is a thing. That is, the current control unit 80 supplies a random amount of current to the electromagnets 25, 35, and 45 within the range of the maximum supply current amount and the minimum supply current amount. In the present embodiment, the maximum supply current amount is a current amount at which the magnetic flux density generated by the electromagnets 25, 35, 45 is 150 mT, and the minimum supply current amount is also the magnetic flux density generated by the electromagnets 25, 35, 45 is 35 mT. The amount of current is as follows.
In the supply current strength pattern shown in FIG. 10, the supply time for supplying current to the electromagnets 25, 35, 45 is also a random time, but the supply time may be a predetermined time set in advance.

Next, the strength pattern of the supply current shown in FIG. 11 will be described.
The intensity pattern of the magnetic flux density generated by the electromagnets 25, 35, and 45 by the current supplied from the current control unit 80 illustrated in FIG. 11 is the same as the first magnetic flux density and the magnetic flux density generated by the electromagnets 25, 35, and 45. 2 types of magnetic flux densities of 2 are generated (the amount of current supplied to the electromagnets 25, 35, 45 is only two types of current amounts, the first current amount and the second current amount). This is different from the strength pattern of the current supplied to the electromagnets 25, 35, and 45 illustrated in FIG.
Specifically, a reference current amount that is a current amount necessary for generating a reference magnetic flux density (35 mT in this case) as a reference in magnetic therapy is set as the first current amount, and the second current amount is set as the first current amount. The current amount is larger than the current amount (here, 150 mT). The current control unit 80 alternately supplies the first current amount and the second current amount set in this way for each required time. In the present embodiment, the first current supply time for supplying the first current amount to the electromagnets 25, 35, 45 is 2.5 seconds, and the second current amount is supplied to the electromagnets 25, 35, 45. The current supply time was 0.5 seconds.

The first current supply time and the second current supply time are not limited to the above-described supply time, and other supply times may be adopted. As illustrated in FIG. The second current supply time can also be a random supply time.
10 to 12, the change in the magnetic flux density generated by the electromagnets 25, 35, and 45 (the amount of current supplied to the electromagnets 25, 35, and 45) changes discontinuously. It is not limited. For example, the current control unit 80 supplies power to the electromagnets 25, 35, and 45 so that the magnetic flux density generated by the electromagnets 25, 35, and 45 (the amount of current supplied to the electromagnets 25, 35, and 45) is continuously changed. It is also possible to control the supply state.
Furthermore, a current supply time setting unit (both not shown) for setting the values input by the user through the input means as the first current supply time and the second current supply time can be provided. The current supply time setting unit can be built in the current control unit 80.

  In the present embodiment, the light emitted from the LED 29A and the LED 29A is detected as first means (and second detection means) for detecting the rotation angle of the left panel part 20 and the right panel part 40 with respect to the central panel part 30. Although a configuration example using the phototransistor 29B has been described, the configuration of the first detection means (and the second detection means) is not limited to this embodiment. Even in the case where the rotation state of the left and right panel portions 20 and 40 with respect to the central panel portion 30 is detected by an optical signal as in the present embodiment, other known configurations can be employed.

  Further, the signal for detecting the rotation state of the left and right panel portions 20 and 40 relative to the central panel portion 30 is not limited to the optical signal. As a detection signal other than the optical signal, for example, a magnetic signal or the like can be used. Furthermore, not only a non-contact type detection means such as a detection means for detecting an optical signal or a magnetic signal, but also a contact type detection means comprising a rotary switch used in contact with the electrodes can be used.

  Furthermore, the magnetic pole states of the electromagnets 25, 35, and 45 of the left panel unit 20, the central panel unit 30, and the right panel unit 40 in the above embodiment are merely examples of a plurality of combinations. As another embodiment, the magnetic treatment device 10 may be configured by four or more panel bodies, and at least one of the left panel portion 20, the central panel portion 30, and the right panel portion 40 may be configured by a plurality of panel bodies. it can. In order to easily control the orientation of the magnetic poles of the electromagnets 25, 35, 45 in accordance with the rotation angles of the left panel unit 20 and the right panel unit 40 with respect to the central panel unit 30, the left panel unit 20 and the central panel respectively. What is necessary is just to make the number of each panel body which comprises the part 30 and the right panel part 40 the same.

As described above, in the present embodiment, the magnetic therapy device 10 is described in a form in which a plurality of panels are connected so as to be bent, such as the left panel unit 20, the central panel unit 30, and the right panel unit 40. However, the mechanism for switching the magnetic poles according to the connection angle of the left panel part 20, the central panel part 30, and the right panel part 40 can be omitted. Moreover, only a single panel part may be sufficient.
In short, the amount of current supplied to the electromagnets 25, 35, 45 disposed in the left panel unit 20, the central panel unit 30, and the right panel unit 40 is not constant, and is generated by each electromagnet 25, 35, 45. Even if the magnetic field (magnetic flux density) is changed and used continuously for a long time, it is only necessary to prevent the body's magnetic habituation phenomenon.
