However, in this electric potential therapy device, the backrest portion and the seat portion are formed linearly in the left-right direction. Therefore, when a user sits on this electric potential therapy device, there is a risk that the user's posture may turn left or right or tilt left or right. In other words, when the user sits on the electric potential therapy device, the user's posture may not be good.
If the posture of the person sitting on the electric potential therapy device is not good, the muscles around the user's back and neck become tense, the blood flow of the user becomes poor, headaches and stiff shoulders develop, and autonomic nerves are affected. becomes unstable and the user is no longer in a relaxed state, causing insomnia, or if the user's abdomen is pressed, the user's intestinal movements (segmental movements, peristalsis, etc.) become difficult to perform. Symptoms of constipation may develop.
For this reason, when this electric potential treatment device applies electric potential treatment to a user who is seated in a bad posture, there is a possibility that the action of the electric potential treatment may not be effectively given to the user.

The present invention has been completed based on the above circumstances, and an electric potential therapy that allows sitting in a correct posture and can better alleviate the symptoms of headache, stiff shoulders, insomnia, and constipation. The purpose is to provide a vessel.

The electric potential therapy device of the first invention comprises a backrest portion having a curved surface recessed so that the left and right central portions of the front surface are located at the rearmost position;
a seat portion whose upper surface slopes downward toward the backrest;
an electrode provided on the backrest portion or the seat portion;

The electric potential therapy device of the second invention includes a backrest portion having a curved surface recessed so that the left and right central portions of the front surface are located at the rearmost position;
a seat portion whose upper surface slopes downward toward the backrest;
an electrode provided on the backrest or the seat,
The upper sides of the left and right side edges of the backrest are formed to extend forward.

In the electric potential therapy devices of the first and second inventions, when the user sits on the seat, the seat that slopes downward toward the backrest makes it difficult for the user's buttocks to separate from the backrest. As a result, the user's ilium and lumbar vertebrae are aligned with the front surface of the backrest. Furthermore, the curved surface of the backrest prevents the user's body from turning or tilting to the left or right, allowing the user to sit in a correct posture, and the back and neck of the user to be seated. Blood flow is improved because muscle tension is relieved. As a result, the symptoms of headache and stiff shoulders of the user can be alleviated. Furthermore, since the autonomic nerves are stabilized and the user is in a relaxed state, the user's insomnia can be alleviated. In addition, since the user's abdomen is less likely to be pressed by the ilium along the front surface of the backrest, the user's intestinal movement (segmental movement, peristaltic movement, etc.) is facilitated, and the user's constipation is relieved. Can relieve symptoms.
Further, in the electric potential therapy devices of the first and second inventions, the curved surface of the backrest portion and the seat portion inclined downward toward the backrest portion guide the position of the user's body to the position of the electrode. can do. Further, in the electric potential therapy devices of the first and second inventions , the user can sit deeply due to the seat section that slopes downward toward the backrest section. As a result, the user's tension caused by being conscious of using the electric potential therapy device can be alleviated.
Furthermore, the electric potential therapy devices of the first and second inventions can apply electric potential therapy to the user by means of the voltage generated at the electrodes. Accordingly, when voltage is generated at the electrodes of the electric potential therapy device while the user is seated on the seat, the symptoms of headache, stiff neck, insomnia, and constipation of the user can be alleviated.
In other words, the electric potential therapy devices of the first and second inventions relieve headaches, stiff shoulders, insomnia and constipation of the user by applying electric potential therapy while the user is sitting on the seat in a correct posture. Symptoms can be better relieved. Also, if the length of the heater wire in contact with the electrodes is long, the voltage generated at the electrodes may not reach the desired level. For this reason, in the electric potential therapy device of the first invention, the electrodes are superimposed on the region of the heater member where the heater wires are sparsely wired, and the length of the heater wires in contact with the electrodes is suppressed, so that the voltage generated at the electrodes is as desired. can be easily reached.

Therefore, the electric potential therapy device of the present invention allows a person to sit in a correct posture, and can better relieve symptoms of headache, stiff shoulders, insomnia, and constipation.

As shown in FIGS. 4 and 5, the first seat cushion member 12 covers the front-rear central portion of the upper surface of the seat body 11E. Also, the first seat cushion member 12 is arranged between the pair of projections 11D of the seat body 11E (see FIG. 5). The rear end of the surface of the first seat cushion member 12 is formed so as to be continuous with the lower end of the front surface of the backrest portion 16 (see FIG. 4).

As shown in FIGS. 2, 4 and 5, the first seat cushion member 12 is provided with a first functional storage portion 12A and a pair of second functional storage portions 12B. A connection box 71, which is a function unit 75, which will be described later, is stored in the first function unit storage unit 12A. In addition, one motor 78A, which is a part of a pair of vibration units 78, which is a function section 75, is housed in each of the second function section housing sections 12B.
Specifically, as shown in FIGS. 2 and 4, the first functional part storage part 12A is located on the left side of the center of the upper surface of the seat main body 11E, and is the first seat part in the vicinity of the backrest part 16. It is formed through the cushion member 12 in the thickness direction. The first functional part storage part 12A has a substantially rectangular parallelepiped shape elongated in the left-right direction.
Further, the first functional part storage part 12A and the recessed part 11B of the seat main body 11E communicate with each other through a communication hole 11C as shown in FIG. Specifically, one end of the communication hole 11C is inside the first functional part housing part 12A and is open to the left side of the plane forming the first functional part housing part 12A. The other end of the seat cushion member 12 and the seat body 11E is open to the rear end of the upper surface of the surface forming the recess 11B.
As shown in FIGS. 2 and 5, the pair of second function storage portions 12B are provided at the left and right end portions of the first seat cushion member 12 and at the center of the first seat cushion member 12 in the front-rear direction. It is The second functional part storage part 12B has a substantially rectangular parallelepiped shape. The second functional part storage part 12B penetrates the first seat part cushion member 12 in the thickness direction (not shown).

The second seat cushion member 13 is, for example, a porous body made of a known low-resilience urethane foam, which is a foamed resin. As shown in FIGS. 4 and 5, the second seat cushion member 13 covers the front end of the upper surface of the seat body 11E. The second seat cushion member 13 is arranged between the pair of projections 11D of the seat main body 11E. The rear end of the upper surface of the second seat cushion member 13 is substantially flush with the front end of the upper surface of the first seat cushion member 12 . The front end of the upper surface of the second seat cushion member 13 curves forward and upward, and is formed substantially flush with the upper end of the front surface of the seat main body 11E (see FIG. 4).

The backrest portion 16 is made of, for example, a known foamed polystyrene, which is a porous body and foamed resin, and is formed integrally with the seat portion main body 11E. That is, the backrest portion 16 is made of foamed polystyrene, which is a porous material.
As shown in FIG. 2 , the backrest portion 16 includes a first support portion 17 forming a left-right central portion of the backrest portion 16 and a pair of left-right symmetrical second support portions forming left-right side edge portions of the backrest portion 16 . It has a support portion 18 . The first support portion 17 extends upward from the rear end portion of the seat body 11E. Each of the second support portions 18 extends obliquely forward from both left and right side edges of the first support portion 17 so that the distance therebetween increases forward. As a result, the backrest 16 forms a concave curved surface 16A so that the left and right central portions of the front surface are positioned furthest to the rear in plan view from above (see FIG. 2). In addition, the lower side of each second support portion 18 is inclined rearward as it goes downward. Accordingly, when the user 50 who is seated on the seat portion 11 stands up, the user 50 can put his or her hand on the upper surface of the seat portion 11 to easily stand up. In addition, since each of the second support portions 18 only touches part of the left and right sides of the back 52 of the user 50 seated on the seat portion 11, the left and right sides of the back 52 of the user 50 are less likely to get stuffy. , it is possible to make it difficult for the user 50 to feel oppressive. In addition, as shown in FIG. 4, the front surface of the first support portion 17 of the backrest portion 16 is inclined rearward at a higher degree toward the upper side. Accordingly, when the user 50 sits on the seat portion 11 , it becomes easier for the user 50 to lean against the first support portion 17 and the second support portion 18 . Therefore, the weight of the user 50 can be distributed to the first support portion 17 and the second support portion 18 as well. Furthermore, the chest of the user 50 is less likely to be compressed, allowing the user 50 to breathe more deeply, thereby allowing the user 50 to sit in a relaxed state. Further, the thickness of the first support portion 17 in the front-rear direction is formed to decrease with increasing distance from the seat portion body 11E in the upward direction. That is, the front surface of the first support portion 17 of the backrest portion 16 is curved forward in the vertical direction.
Therefore, as shown in FIG. 9 , when the user 50 sits on the seat portion 11 , the buttocks 51 of the user 50 can easily approach the backrest portion 16 and become difficult to move away from the backrest portion 16 . Then, the ilium 54 and the lumbar vertebrae 55 of the user 50 follow the forward curvature of the front surface of the backrest 16 . At this time, the lumbar vertebrae 55 are S-shaped.
Further, when the user 50 sits on the seat portion 11, the curved surface 16A of the backrest portion 16 prevents the body of the user 50 from turning left and right or leaning left and right. The user 50 is thus in the correct posture. As a result, tension in the muscles around the back 52 and the neck of the user 50 is relieved, so that the blood flow of the user 50 is improved, and the symptoms of headache and stiff shoulders of the user 50 can be alleviated. Furthermore, since the autonomic nerves are stabilized and the user 50 is in a relaxed state, insomnia of the user 50 can be alleviated. In addition, since the ilium 54 extends along the front surface of the backrest portion 16, the abdomen of the user 50 spreads in the vertical direction and is less likely to be compressed, so that the user's 50 intestinal movement (segmental movement, peristaltic movement, etc.) is performed. It becomes easy and the symptom of constipation of the user 50 can be relieved.
When the upper surface of the second support portion 18 is positioned above the position where the lower part of the thoracic spine of the user 50 seated on the seat portion 11 is supported, the user 50 seated on the electric potential therapy device 10 is positioned upward. may feel oppressive. In addition, when the upper surface of the second support portion 18 is vertically positioned below the position supporting the lower thoracic spine of the user 50 seated on the seat portion 11, the user 50 seated on the electric potential treatment device 10 There is a risk that the body of the child will be more likely to turn left or right or lean left or right. For this reason, it is preferable that the upper surface of the second support portion 18 be vertically positioned so as to support the lower part of the thoracic spine of the user 50 seated on the seat portion 11 . Accordingly, the user 50 seated on the seat portion 11 can rest his or her elbows on the upper surfaces of the second support portions 18, and can read or the like while resting their elbows on the upper surfaces of the second support portions 18. . Further, when the user 50 who is seated on the electric potential therapy device 10 stands up, the user can put his or her hand on the upper surface of each second support portion 18 and can easily stand up.

The front surface of the first support portion 17, which is the left-right central portion of the curved surface 16A, is a region where the left-right central portion of the back 52 of the user 50 seated on the seat portion 11 can come into contact (see FIGS. 2 and 9). The front surfaces of the second support portions 18, which are the left and right sides of the curved surface 16A, are areas where the left and right sides of the back 52 of the user 50 seated on the seat 11 can come into contact (see FIGS. 2 and 9). In addition, the electric potential therapy device 10 can be easily carried by the user 50 holding the front end of each second support 18 .

The surface cushion member 14 is, for example, a porous body and is made of known foamed urethane, which is a foamed resin. In the surface cushion member 14, a connection box 71, which will be described later, is housed in the first functional part housing part 12A of the first seat part cushion member 12, and a pair of vibration units 78, which will be described later, are housed in each of the pair of second function part housing parts 12B. is installed after the motor 78A, which is part of the .
The surface cushion member 14 includes the front surface of the seat body 11E, the upper surface of the pair of convex portions 11D of the seat body 11E, the upper surface of the second seat cushion member 13, the upper surface of the first seat cushion member 12, and the backrest. 16 covers these surfaces along the front and top surfaces. The rear end surface of the surface cushion member 14 covering the upper surface of the backrest portion 16 is substantially flush with the upper end of the rear side surface of the backrest portion 16 . The lower end surface of the surface cushion member 14 covering the front surface of the seat main body 11E is substantially flush with the front end of the bottom surface of the seat main body 11E.

In the electric potential therapy device 10, when the user 50 sits on the seat portion 11, the surface cushion member 14, the first seat portion cushion member 12, and the second seat portion cushion member 13 are deformed, and the buttocks 51 and the buttocks 51 of the user 50 are deformed. The surface of the surface cushion member 14 is in close contact with the base of the thigh 53 and the back 52 (see FIG. 9). As a result, the electric potential therapy device 10 can evenly distribute the weight of the user 50 on the surface cushion member 14 to which the user's 50 buttocks 51, thigh roots 53, and back 52 are in close contact.

The controller 70 has a first housing 70A and a first substrate 70B, as shown in FIG. The first housing 70A is, for example, a box made of synthetic resin and having a substantially rectangular parallelepiped shape. The outer shape of the first housing 70A is substantially the same as the shape of the space formed by the recess 11B of the seat main body 11E (see FIG. 5). The first board 70B is housed in the first housing 70A, and an electric circuit is formed by various mounted electronic components. The control unit 70 is supplied with power from a commercial power supply (not shown) to the first substrate 70B through a power cord 76J, and operates based on this power. The control unit 70 can control the operation of a function unit 75, which will be described later, by operating an operation unit 80, which will be described later. That is, the control section 70 controls the operation of the function section 75 . The control unit 70 is housed in the recessed portion 11B and fixed to the fixed plate 19 with its back surface in contact with the left surface of the fixed plate 19 . A socket 70C is provided in the first housing 70A. Power can be supplied to the blanket 77 by inserting a plug 77G of the blanket 77, which will be described later, into the socket 70C.

The functional section 75 has a connection box 71 , a pair of vibration units 78 , a first heater member 72 and a second heater member 73 that are heater members, and an electrode 74 .
The connection box 71 has a second housing 71A and a second substrate 71B.
The second housing 71A is, for example, a box made of synthetic resin and having a substantially rectangular parallelepiped shape. The outer shape of the second housing 71A is substantially the same as the shape of the space formed by the first functional part storage part 12A of the first seat part cushion member 12. As shown in FIG.
The second substrate 71B is accommodated in the second housing 71A, and an electric circuit is formed by various mounted electronic components. The second substrate 71B and the first substrate 70B are electrically connected via two parallel cables 76A and 76B. The cable 76A is formed by bundling four harnesses in parallel. Also, the cable 76B is formed by bundling five harnesses in parallel with each other.

The connection box 71 constructed in this way is housed in the first functional housing 12A (see FIG. 4). Cables 76A and 76B are inserted through the communication hole 11C to electrically connect the second substrate 71B and the first substrate 70B. When power is supplied from the first substrate 70B to the second substrate 71B, the connection box 71 is connected to a pair of vibrating units 78 described later, a first heater member 72 described later, a second heater member 73 described later, and an electrode 74 described later. Power is distributed and supplied to each of the

Each of the pair of vibration units 78 has a motor 78A and a motor fixing plate 78B. The motor 78A is composed of, for example, a known unbalanced motor or the like, and its rotor rotates and vibrates when power is supplied. The motor 78A is electrically connected to the second board 71B via two harnesses 76C that are parallel to each other. The motor fixing plate 78B is a substantially square flat plate. The motor fixing plate 78B is made of synthetic resin, for example. One motor 78A is fixed to each motor fixing plate 78B so that the rotation of each rotor is not hindered. Each vibrating unit 78 constructed in this way accommodates one motor 78A in each of the pair of second function housings 12B, and each motor fixing plate 78B closes the opening of each second function housing 12B. Each motor fixing plate 78B is adhered to the upper surface of the first seat cushion member 12 (see FIG. 2).

As shown in FIG. 6B, the first heater member 72 includes a base material 72A, electric wires 72B that are heater wires, and nonwoven fabric 72C. The base material 72A is made of felt and has a rectangular shape. A known cord heater, for example, is used for the electric wire 72B. The nonwoven fabric 72C is a cloth having approximately the same size as the base material 72A. In the first heater member 72, an electric wire 72B is wired in a zigzag manner on one surface of a substrate 72A. The nonwoven fabric 72C is attached to one surface of the base material 72A on which the electric wires 72B are wired, covering the electric wires 72B.
The first heater member 72 is attached to the upper surface of the surface cushion member 14 located between the pair of convex portions 11D and forward of the front end of the first functional portion housing portion 12A (see FIG. 6A). .).

When the user 50 sits on the seat portion 11, the first heater member 72, the surface cushion member 14, the first seat portion cushion member 12, and the second seat portion cushion member 13 are deformed. In particular, the central portion of the first heater member 72 tends to bear the weight of the user 50 and sinks the most. Therefore, if the electric wire 72B is wired in the central portion of the first heater member 72, the electric wire 72B may be displaced from the base material 72A or may be disconnected.
In order to prevent the electric wire 72B from being displaced with respect to the base material 72A or being disconnected, the electric wire 72B is attached to the upper surface of the surface cushion member 14 in the state shown in FIG. ), wiring is provided at both the left and right ends and the rear end of the rectangular substrate 72A, and is not provided at the central portion and the left-right center of the front end of the substrate 72A. That is, when the first heater member 72 is adhered to the upper surface of the surface cushion member 14, the electric wires 72B are wired more densely on the rear side than on the front side, and the electric wires 72B on the front side are sparsely arranged on the front side than on the rear side. is wired to In other words, the first heater member 72 has the electric wires 72B wired on the upper surface of the surface cushion member 14 located on the upper surface of the seating portion 11 in a planar manner.

Both ends of the electric wire 72B are drawn out from the rear end of the left end portion of the base material 72A. Both ends of the lead wire 72B are electrically connected to the second substrate 71B via two harnesses 76D that are parallel to each other.

Further, when the electrode 74 is in the ON state (that is, while the user 50 uses the operation unit 80 to switch the state of the electrode 74 to the ON state and maintains the ON state), the motor 78A of the vibration unit 78 is turned on. It is intermittently driven to vibrate the motor 78A intermittently. Thereby, the user 50 can be notified that the electrode 74 is on.

Thus, in the electric potential therapy device 10 , when the user 50 sits on the seat 11 , the seat 11 tilts downward toward the backrest 16 so that the buttocks 51 of the user 50 are separated from the backrest 16 . it gets harder. Thereby, the ilium 54 and the lumbar vertebrae 55 of the user 50 are along the front surface of the backrest portion 16 . Furthermore, the curved surface 16A of the backrest 16 prevents the body of the user 50 from turning left or right or leaning left or right, so that the user 50 can sit in a correct posture. Since the tension in the muscles around the back 52 and neck is relaxed, the blood flow is improved. As a result, the symptoms of headache and stiff shoulders of the user 50 can be alleviated. Furthermore, since the autonomic nerves are stabilized and the user 50 is in a relaxed state, insomnia of the user 50 can be alleviated. In addition, since the ilium 54 is along the front surface of the backrest portion 16, the abdomen of the user 50 is less likely to be pressed, so that the user 50 can easily perform intestinal movements (segmental movements, peristaltic movements, etc.). The symptoms of constipation of the person 50 can be alleviated.
Furthermore, when a voltage is generated at the electrodes 74 of the electrotherapeutic device 10, the electrotherapeutic device 10 can apply the electrotherapeutic treatment to the user 50 by means of this voltage. Accordingly, when a voltage is generated at the electrodes 74 while the user 50 is seated on the seat portion 11, the symptoms of the user 50 such as headache, stiff neck, insomnia, and constipation can be alleviated.
In other words, the electric potential therapy device 10 provides electric potential therapy to the user 50 while the user 50 is in a correct posture while sitting on the seat 11, thereby improving the symptoms of the user 50 such as headache, stiff neck, insomnia, and constipation. can be mitigated to
In addition, the electric potential therapy device 10 guides the body position of the user 50 to the position of the electrode 74 by the curved surface 16A of the backrest 16 and the seat portion 11 inclined downward toward the backrest 16. be able to. In addition, the electric potential therapy device 10 allows the user 50 to sit deeply on the seat portion 11 that slopes downward toward the backrest portion 16 . As a result, the tension of the user 50 caused by being conscious of using the electric potential therapy device 10 can be alleviated.

Therefore, the electrotherapeutic device 10 of the present invention can be seated in a correct posture, and can better relieve symptoms of headache, stiff shoulders, insomnia and constipation.

Also, the electrodes 74 of the electric potential therapy device 10 are of a contact type. Therefore, the electric potential therapy device 10 can uniformly apply the voltage generated by the electrodes 74 to the entire body of the user 50 with only a portion of the electrodes 74 contacting the user 50 .

Also, the electrodes 74 of the electric potential therapy device 10 are provided on the upper surface of the seating portion 11 . When the user 50 is seated on the seat 11 , the buttocks 51 and the roots 53 of the thighs of the user 50 are less likely to leave the seat 11 . Therefore, by providing the electrodes 74 on the upper surface of the seating portion 11, the electrodes 74 can be brought into contact with the body of the user 50 more reliably.

A first heater member 72 having electric wires 72B arranged sparsely and densely in a plane is provided on the upper surface of the seating portion 11, and electrodes 74 are superimposed. If the length of the wire 72B in contact with the electrode 74 is increased, the voltage generated at the electrode 74 may not reach the desired magnitude. Therefore, in the electric potential therapy device 10, the electrodes 74 are superimposed on the area on the front side of the first heater member 72 where the electric wires 72B are sparsely wired in a planar shape, and the length of the electric wires 72B in contact with the electrodes 74 is suppressed. The voltage developed at 74 can be made easier to reach the desired magnitude.

In addition, the seat portion 11 is provided with recessed portions 11F recessed in the rearward direction at the left and right central portions of the front surface. Therefore, in the electric potential therapy device 10, when the user 50 sitting on the seat portion 11 stands up, the position of the center of gravity of the user 50 is positioned on the user's 50 feet by placing the feet in the recessed portions 11F. Since it can be made easy to move, the user 50 can easily stand up.
Further, when the electric potential therapy device 10 is installed on the installation surface L, it is necessary to install it on the installation surface L via the insulating member 21 having no electrical conductivity. Further, the insulating member 21 needs to provide a predetermined area S in which the feet of the user 50 are placed forward from the front side of the seat portion 11 . That is, the electric potential therapy device 10 can widen the predetermined region S where the user's 50 feet are placed by the recessed portion 11F. As a result, when the user 50 sitting on the electric potential therapy device 10 stands up, the feet of the user 50 can be easily kept within the predetermined area S by arranging the feet in the recessed portions 11F. The chance that the foot contacts the installation surface L can be suppressed.
