Summary of the Invention

Problems to be Solved by the Invention

[0004] In the electrical stimulation device of Patent Document 1, the portions for placing the soles of the left and right lower limbs are simply formed symmetrically left and right, and no consideration is given to the directionality when placing the soles. However, usually, when a person sits with both feet aligned, the soles of the sitter's feet tend to open forward. In a floorboard without directionality like the electrical stimulation device of Patent Document 1, the user may feel forced to have an unnatural foot orientation, which is confusing and difficult to use. And when the foot orientation is unnatural, the stimulation current is applied. is applied. In the case of the board, the user may feel forced to have an unnatural foot orientation, which is confusing and difficult to use. And when the foot orientation is unnatural, the stimulation current When muscles contract in response to the electrical current, the soles of the feet lift off the electrodes, for example, only the fingertips can touch the electrodes. When the device comes into contact with the muscle, it is not possible to ensure the required amount of electrical current is supplied to the muscle, and therefore insufficient massage cannot be performed. There is a risk that it may not be possible. Also, if the position of the feet is unnatural, the feet may move due to muscle contractions, etc. If you do that, there is a risk that your fingertip will touch the other electrode. In such cases, the stimulating current However, it hardly reaches the muscles of the lower limbs, such as the calf, and instead travels between both electrodes and the sole of the foot. A closed circuit of stimulating current is formed, which can cause the toes to move unnecessarily, thus preventing effective muscle massage. There was also a risk that the surge could not be performed.

[0005] The objective of this invention is to provide an easy-to-use electrical stimulation device that allows the user to recognize the direction of the soles of their feet. It is about doing it. [Means for solving the problem]

[0006] To achieve the above objective, the present invention has a sheet-like pad, and the upper surface of the pad The electrical stimulation device is equipped with electrodes for applying an electric current to the lower limbs via the soles of the feet, The pad is characterized by having a shape that indicates the direction in which the sole of the foot should be placed.

[0007] In the electrical stimulation device configured as described above, the user stimulates the soles of their feet according to the external shape of the device. Because it allows users to be mindful of the natural orientation of the device, they can move their lower limbs without being forced into an awkward position. In contrast, a stimulating current can be applied. [Effects of the Invention]

[0008] As described above, according to the present invention, the user can position the soles of their feet according to the external shape of the electrical stimulator. Because electrical stimulation can be performed smoothly once the direction is determined, it is easy to use as an electrical stimulation device. exerts the resulting effects.

Modes for Carrying Out the Invention

[0010] (Embodiment) Hereinafter, embodiments embodying the present invention will be described based on the drawings. Figs. 1 to 8 show this embodiment. As shown in Figs. 1, 2 and 4, the electrical stimulation device 11 of this embodiment includes a flat sheet-like pad 12 and a controller 13 detachably attached to the central portion of the upper surface of the pad 12. In the electrical stimulation device 11 of this embodiment, the upper part of Figs. 1 and 2 is taken as the front side. ​

[0011] As shown in Figures 1 and 2, the pad 12 is located in the left zone 2 on which the sole of the left foot F rests. It has 1 and a right zone 22 on which the sole of the right foot F rests, and their outer edges 23 are It is sloped to widen towards the front, and the angle of inclination is 15 degrees relative to the front-to-back line. This is the degree. A value of 3 to 30 degrees is preferable for this inclination angle. Figure 1 shows the sole of the foot F, indicated by the dashed line. To ensure comfort, the inclination angle of the outer edge 23 indicates the angle at which the user's sole F is placed. There are recesses in the center of both the front and rear ends of the pad 12 that extend forward and backward, respectively. 24 and 25 are formed. These recesses 24 and 25 are located in the left zone 21 and the right zone 2 It is formed by providing inclined portions 241 and 251 at both the front and rear positions of 2. Also, the left zone Zones 21 and the right zone 22 are formed with the front side (toe side) being wider than the rear side (heel side). It is being done.

[0012] As shown in Figure 4, the pad 12 is divided and arranged into a left zone 21 and a right zone 22. A pair of cushioning materials 26 having flexibility and electrical insulation properties, and on the cushioning materials 26 It is attached to the surface, forms a single unit on both sides, is harder than cushioning material, and has electrical insulating properties. It has several surface sheets 27. The cushioning material 26 is made of, for example, foamed polyurethane. The surface sheet 27 is constructed of, for example, polyethylene terephthalate. The opposing inner end faces 29 of the left and right cushioning materials 26 are tilted to widen downwards. They are angled, and a gap 28 is formed between them. Of the left and right cushioning materials 26 Between the side end faces 29, the upper surface of the surface sheet 27 has shallow grooves, and in the front-rear direction. An extending fold line 31 is formed. As shown in Figures 5 and 6, this fold In line 31, the unfolded surface sheet 27 is positioned so that the surface sheet 27 faces inward. Fold the cushioning material 26 so that it faces outwards, and fold the entire pad 12 in half. It is possible.

[0013] As shown in Figure 3, the left and right cushioning materials 26 are treated with an anti-slip coating 32. In Figure 3, the anti-slip treatment 32 is made of a rubber material with a high coefficient of friction and flexibility, such as an elastomer. The diagram shows a configuration in which numerous non-porous materials are placed in specific spots, but the back surface of the cushioning material 26 has irregularities. It may be constructed by applying processing or other methods. And this anti-slip processing 32 comes into contact with the floor surface. This suppresses the sliding of the pad 12.

[0014] As shown in Figures 1 and 2, the entire upper surface of the left zone 21 and right zone 22 of the surface sheet 27 Each body has a conductive pattern 41 made of a conductive paste containing conductive metals such as silver and copper. The conductive patterns 41 on the left and right avoid the portion of the bending line 31. They are positioned independently on the left and right sides, and when the pad 12 is folded, the conductive pattern 41 is on the inside. It is located there. And this conductive pattern 41 is for applying voltage to the sole F of the user's foot. The electrodes are formed. This conductive pattern 41 follows the contours of the left zone 21 and the right zone 22. The front side has a wider contour portion 42 than the rear side, and the contour portion 4 is located within the contour portion 42. It has an inner portion 43 consisting of a plurality of parallel straight lines electrically connected to 2. The inner portion 43 extends parallel to the outer edges 23 of the left zone 21 and the right zone 22. Therefore, the inner portions 43 of the left zone 21 and the right zone 22 are inclined in a forward-spreading manner. As shown by the dashed line in Figure 1, the angle of the user's sole F is indicated.

[0015] As shown in Figures 2 and 4, the front of both sides of the left zone 21 and the right zone 22 The surface sheet 27 on the contour portion 42 will serve as electrodes for supplying power to the conductive pattern 41. The connection terminal 44 is attached in a symmetrical position on the left and right sides via the bending line 31. The connecting terminal 44 is formed in the shape of the convex side of a snap button. On the back surface of the controller 13 A connection terminal 45 is provided that can be connected to and separated from the aforementioned connection terminal 44. This connection terminal 45 is formed in the shape of the recessed side of a snap button, and the electrical circuit inside the controller 13 This constitutes the output electrode of the circuit. Note that in Figure 4, the protruding height of the connection terminal 44 is depicted in an exaggerated manner. However, when the pad 12 is folded, the surface sheet 27 and cushioning material 26 change Depending on the shape, the connector terminal 44 will sink down, so the connector terminal 44 will not interfere with folding. stomach.

[0016] The controller 13 is equipped with a power supply, an oscillator circuit, and a control circuit (none of which are shown in the diagram). The stimulation current generated by the oscillation circuit is transmitted through connection terminals 44 and 45 to the conductive pattern 41. It is supplied to the body. This stimulating current is an EMS (Electrical Muscle Stimulation) current. It consists of current pulses of 15-20 Hz. The top surface of the controller 13 has indicators for varying the strength of the stimulating current. This adjusts the current supply pattern, such as changing the frequency, and also controls the on / off switch for the stimulation current output. Operating switches 46 and 47, which also serve other functions, are provided. The power supply is a lithium-ion battery. A secondary battery such as an ON battery is used, and the outer surface of the controller 13 is used to charge this secondary battery. A connector (not shown) is provided for this purpose.

[0017] As shown in Figure 1, the electrical stimulation device 11 of this embodiment has the controller 13 wirelessly controlled. A remote control unit (hereinafter referred to as "remote control") 51 is provided for this purpose. This remote control 51 has an operating switch that has the same function as the operating switches 46 and 47. Sections 52 and 53 are provided.

[0018] Figure 7 shows a bag 81 for storing the electrical stimulator 11, which is folded in half. Furthermore, the folded pad 12 can be inserted and removed by opening and closing the zipper 82. Bag 81 Inside is a pocket (not shown) for housing the controller 13 and the remote control 51. It is provided.

[0019] Next, we will explain how to use the electrical stimulation device 11 configured as described above. When using this electrical stimulator 11, the pad 12 should be in the unfolded state as shown in Figure 8. In addition, the surface sheet 27 is placed on the floor with the top side facing upwards. Also, the contact of the controller 13 Connect the connection terminal 45 to the connection terminal 45 of the conductive pattern 41. With this in place, sit in the chair. The user places the soles of their left and right feet F on the inner parts 43 of the left and right conductive patterns 41, respectively. Operate the control switches 46, 47 on the device 13 or the control switches 52, 53 on the remote control 51. Then, the controller 13 supplies a stimulating current, which is an EMS current, to the left and right conductive patterns 41. And this stimulating current is transmitted through the conductive pattern 41 and the sole of the user's foot F to the user's feet. It is supplied to the limbs. Therefore, the muscles of the user's lower limbs, especially the muscles below the knee, and especially the calf muscles. The repeated contraction and relaxation of muscles allows for training of those muscles and improves blood flow. can.

[0020] When the use of the electrical stimulator 11 is finished, remove the controller 13 from the pad 12, and then... The left and right conductive patterns 41 of the surface sheet 27 are aligned at the folding line 31 of the surface sheet 27. When folded so that they touch, pad 12 becomes half the size of its unfolded state. Therefore, pad If unit 12 is stored in bag 81 along with the controller 13 and remote control 51, it can be conveniently carried. Furthermore, it can be stored without taking up much space, even if it's not placed inside bag 81.

[0021] This embodiment has the following effects: (1) The outer edges 23 of the left zone 21 and right zone 22 of the pad 12 widen forward. There is also a recess 24 that extends forward between the left zone 21 and the right zone 22. It is formed in such a way that the user can follow the shape of its outer edge 23 and recess 24 with the sole of their foot. It is understood that you should naturally open F and place it on the left zone 21 and the right zone 22. The user can easily and comfortably place the soles of their feet F onto the conductive pattern 41 without having to assume an awkward posture. It can be placed on the device to induce an electrical stimulation state. Therefore, the lower limbs are stimulated as the stimulating current is applied. Even when the muscles contract, the foot does not make unnecessary movements, for example, the sole of the foot F is conductive The turn 41 lifts up, so that only the fingertip is in contact with the conductive pattern 41. There is no such thing. Also, due to muscle contraction in an unnatural position of the foot, the toes may move to the other electrode. When the conductive pattern 41 is touched, a short-circuit stimulating electric current is generated between the sole of the foot F and both conductive patterns 41. When a closed circuit in the flow is formed, movements other than the required training movements occur in the lower limbs. This is not the case. Therefore, in the electrical stimulation state by the electrical stimulation device 11 of this embodiment, It ensures that sufficient electrical current is always supplied to the muscles of the lower limbs, such as the calves, allowing for effective training. It is possible to perform this action. Moreover, as mentioned above, the user can naturally assume an unnatural posture. Furthermore, the sole of the foot F can be placed comfortably and easily on the conductive pattern 41, so during use This prevents the foot from moving in an unintended direction. Therefore, the movement of the foot... The pad 12 may bend or, conversely, be pulled and become unnaturally tense. This avoids the inconveniences that can occur.

[0022] (2) Moreover, the inner portion 43 of the conductive pattern 41 is also shaped to be extended in a forward-flaring manner. This is achieved. Therefore, the user is prompted by the shape of the conductive pattern 41 to open the soles of their feet forward. It is understood that one should naturally place the object on the left zone 21 and the right zone 22 in the same manner as described above. This allows for a comfortable and natural state of electrical stimulation, enabling effective training. Furthermore, the inner section 43 is formed by drawing multiple parallel lines in a front-opening state, The line serves as a guide when aligning the user's sole F. In other words, for each user, both feet The spacing between the F points on the soles of the feet often varies, and users choose a line that fits the spacing between the F points on their soles. You can select a line and align the sole of your foot F along it. In this way, the inner part 43 By using the lines, you can align the soles of your feet at appropriate and comfortable intervals to receive electrical stimulation comfortably. It is possible.

[0023] (3) Outline of the left zone 21 and right zone 22 of the pad 12 and the shape of the conductive pattern 41 Because the heel side is narrow and the toe side is wide, these shapes allow the wearer's sole to fit comfortably. The orientation of F is guided. Therefore, the user can recognize the orientation of the foot sole F at a glance. This allows the soles of the feet F to be placed correctly in the left zone 21 and the right zone 22 without error. Even if the shape of the conductive pattern 41 is a different shape from that of the embodiment, such as a mesh, the user The system can recognize the direction in which the sole of the foot F is placed based solely on the outlines of the left zone 21 and the right zone 22.

[0024] (4) The pads 12 are separated by the folding line 31, and the conductive patterns 41 are in contact with each other. It can be folded so that it faces inward. Therefore, when the pad 12 is folded, it can be carried and stored. In the tube, damage or peeling of the conductive pattern 41 can be prevented as much as possible. Furthermore, the inner end surface 29 of the thick cushioning material 26 is positioned close to the back side of the pad 12. Therefore, with the conductive pattern 41 facing outwards, the cushioning material 26 faces inwards. Folding is difficult because the inner end faces 29 interfere with each other.

[0025] (5) Since the conductive pattern 41 is formed avoiding the portion of the bending line 31, The conductive pattern 41 is divided by repeated bending and unfolding of the head 12. This prevents peeling or detachment.

[0026] (Example of change) The present invention is not limited to the above-described embodiments, and can be modified as follows: be.

[0027] As shown in Figure 9, the pad 12 is positioned at the location of the folding line 31 in the embodiment. To divide. In this configuration, it is necessary to incline the inner end faces 29 of both cushioning materials 26. It is not necessary. Even with this configuration, the pad 12 is affected by the anti-slip processing 32 on its back side. Because it is non-slip on the floor surface, it does not become difficult to use. And, electrical stimulator 1 When storing or carrying unit 1, the conductive pattern 41 faces inward between the left zone 21 and the right zone 22. They should be overlapped in this manner. Note that in Figure 9, the left zone 21 and the right zone 22 are spaced apart. Although drawn, when used for electrical stimulation, both zones 21 and 22 are not separated by any gap as shown in Figure 1. It will be installed.

[0028] In the split configuration shown in Figure 9, the connection terminal 44 of the pad 12 and the connection terminal 4 of the controller 13 A detachable and easily flexible power supply line shall be provided between 5. With this configuration, the controller 13 can be positioned away from pad 12. And because the power supply line can easily bend and deform, The spacing between the left zone 21 and the right zone 22 can be arbitrarily set. Therefore, the user can use both feet The positions of the left zone 21 and the right zone 22 can be appropriately set in accordance with the spacing of the back F, and electrical stinging This makes it easier to use the stimulator 11.

[0029] As shown in Figure 10, in the divided configuration of Figure 9, the left zone 21 and the right zone 22 The magnets 60 that attract each other to opposing parts are, for example, embedded in or attached to the cushioning material 26. To be installed by means of clothing, etc. In this way, the magnetic force of magnet 60 will cause the left side to be affected. Zone 21 and the right zone 22 can be connected.

[0030] As shown in Figure 11, in the divided configuration of Figure 9, the left zone 21 and the right zone 22 A hinge 61 is interposed between the opposing parts. In this configuration, the pad is connected via the hinge 61. 12 can be easily switched between the unfolded and folded states.

[0031] As shown in Figure 12, in the divided configuration of Figure 9, the left zone 21 and the right zone 22 Metal arms 62 and 63 are provided on it, and the arms 62 and 63 are connected to a metal shaft 64 To be rotatably connected by means of. Also, the controller 13 is mounted in one of the zones 21, 22. Then, connect one of the connection terminals 45 to the conductive pattern 41 of zones 21 and 22. The other connection terminal 45 is connected to the other zone 21, 2 via the arms 62, 63 and shaft 64. Connect to conductive pattern 41 of 2. In this configuration, the opening angle of the user's sole F. Accordingly, the angle between the left zone 21 and the right zone 22 can be changed with respect to axis 64. This makes it easy to use. Also, the left zone 21 and the right zone 22 can be easily deformed. When the electrical stimulator 11 is not in use, the left zone 21 and the right zone 22 rotate around the axis 64. By rotating them, the two zones 21 and 22 can be overlapped in an intersecting manner with slight deformation. This makes it convenient to carry and store.

Arranging and attaching in such a manner. A configuration in which a fabric or knitted material made of conductive fibers is attached. Unlike printed conductive patterns, there is virtually no risk of breakage or peeling. Moreover, if moisture is added to such fabrics or knitted materials, it can cause irritation to the soles of the feet and, consequently, to the lower limbs. This improves the conductivity of the electric current, enabling effective training. Even if the entire fiber is composed of conductive fibers, a portion of the entire fiber is made of conductive fibers. Therefore, it may be constructed in this way.

[0033] Instead of printing the conductive pattern 41 as an electrode, the upper surface of the surface sheet 27 is made conductive The upper surfaces of the left zone 21 and right zone 22 at the outer edge of the fabric or knitted fabric containing fibers It is fixed to the outer periphery by adhesive or other means, and the central area of ​​the fabric or knitted material can be stretched or moved. To do so. With this configuration, the fabric or knitted material will absorb moisture in the same way as described above. This can be done. In addition, the toes and soles of the feet open and close in response to the application of the stimulating current. Furthermore, because the fabric or knit can stretch or move to follow its movements, it can maintain a constant state of electrical conductivity. This allows for uninterrupted and effective training.
