Description

The present invention relates to a low back pain treatment chair that can be treated while holding a posture in which the floor is kneeled when seated and both ankles are slightly lifted from the floor and has a traction effect .

  There are many people in the world who suffer from back pain. This low back pain is said to occur because a human stands on two legs against gravity and moves around while supporting a heavy head, which occupies about 1/10 of the body weight, with the spine and muscles. The spine is curved in an S shape with respect to the side of the body. The spinal nerve passes through the center of this spine. This spine acts as a spring to lighten the burden of gravity. In addition, cartilage called an intervertebral disc serves as a cushion to support the body. In this state, commands from the brain pass through the spinal nerves in the spine and transmit the commands to every corner of the body, and normal operation is performed. When this spine works in the same posture for a long time, fatigue gradually accumulates in the body, and when muscle fatigue accumulates, blood circulation deteriorates and elasticity of muscles and the like becomes poor. In addition, when an abnormality appears in the lumbar spine, a phenomenon occurs in which the lumbar spine warps in the front bay or the back bay. For this reason, the lumbar joint is distorted, and the intervertebral disc supporting the vertebra is strained. As a result, the posture of the body is distorted, and the normal movement of the body becomes impossible due to pressure on the internal organs. This is back pain.

In view of this, there has been proposed a device that corrects the distortion of the posture so that the intervertebral disc supporting the vertebra is not burdened. For example, Patent Document 1 proposes an instrument that uses a back pain treatment instrument in which a column is erected on an abutment placed on the floor and a seat and a pad are provided via an adjustment unit that can adjust the height. Yes. In this low back pain treatment device, a flexible mat-like pad for tightening between the armpit of the chest and the lower rib and between the hip bones is wound around the patient's torso in a front-to-end manner, and the patient is fixed by tightening.
Then, the seat of the lumbago treatment device is unlocked, the patient is suspended, and the lumbar vertebra is extended to treat lumbago.
JP 2000-225137 A

  However, the low back pain treatment device shown in Patent Document 1 corrects a curved lumbar vertebra using its own body weight. Therefore, an excessive burden is applied to the tightened part of the body. In addition, the treatment effect cannot be sufficiently satisfied for the burden on the body. Furthermore, this back pain treatment device has a complicated structure. This low back pain treatment device is high enough to stand upright and strong enough to suspend the patient, and is difficult to use at home.

  The present invention is directed to providing a low back pain treatment chair that corrects the distortion of the posture without imposing a burden on the body, particularly when correcting the above-described conventional problems. Another object of the present invention is to provide a low back pain treatment chair that has a simple structure and can be corrected at home.

The invention according to claim 1 is a polygon in plan view, an oval shape in plan view, or a combination of a polygon and an oval shape in plan view. In a low back pain treatment chair comprising a seat member capable of swinging in a direction and a left-right direction, and a leg member that supports the seat member at a predetermined height position, the leg member is provided on the leg member, In a low position, it sticks out horizontally on both the left and right sides of this seat member, and the user can put the buttocks on the seat member and bend the foot and put the knee on the floor, so that the ankle can be hooked have a ankle engaging member, the ankle engaging member is a chair back pain is provided so as to allow height adjustment.
This seat member needs to have a seating surface of a size that allows the user to place the buttocks, that is, an area that can be seated. The seating surface may be a flat surface, a concave surface, or a convex surface. When viewed in plan, the shape may be oval, polygonal, or a combination of them. In short, the width of the front side of the seat member when seated with a seatable width is the center. It needs to be smaller than that of the department. For example, a saddle shape of a bicycle may be used.
The leg member keeps the height of the seat member so that the user can put his knees on the floor surface when sitting. The leg member is composed of one or more legs, a flat plate that supports the seat member, and the like.
The ankle hooking member can be constituted by, for example, a single bar having a predetermined length. In short, it is necessary that both ends of the ankle retaining member protrude from the seat member by a predetermined length in the width direction. It is necessary to hang both ankles at a slightly higher position than the knee head in the kneeling posture when sitting.
When the user sits on the seat member and bends both feet and puts both knees on the floor, both ankles are hooked on the ankle retaining members, the spine is naturally supported by the buttocks and both knee heads. Can maintain an upright posture. Moreover, since such a posture can be adjusted only by sitting down, it is possible to correct the distortion of the posture without depending on restraint by a restraining tool or the like and without placing an excessive burden on the body.
In addition, when the seat member is viewed in plan, the width is narrowed toward the front, so the thigh does not hit the corner of the chair (front corner) when sitting and bending the foot Can easily bend the foot and hook the ankle.
The seat member has a structure that allows a predetermined angle of oscillation about a predetermined axis.

  The seat member has a structure that can swing with respect to the leg member in all directions within a plane. As a result, when the user is seated on the seat member, the seat member can be tilted sideways (left and right when viewed from the front when seated), so that the ankle can be easily hooked on the ankle hooking member. Further, since it can be tilted forward in plan view, the knee head can be easily put on the floor surface while sitting on the seat member.

In the present invention, the height of the seat member can be adjusted according to the physical characteristics of the patient to be used . For example, a slit is provided in the leg member, and a bolt is inserted through the slit and supported by the seat member, or a plug is screwed into the lower end of the leg member and the length of the leg can be adjusted by the screwing amount of the plug. By doing so, the height of the seat member can be adjusted.
Further, the height of the ankle hooking member can be adjusted according to the physical characteristics of the patient to be used. For example, a horizontal connecting material that bridges the left and right legs is provided, a bolt is attached to the connecting material in a direction perpendicular to the connecting material, and the horizontal ankle retaining member is suspended by this bolt, and the ankle retaining member is a nut. The height of the ankle retaining member can be adjusted by the tightening amount of the nut when supported by.
Further, the ankle hooking member can be structured to be housed on the back side of the seat member. For example, an ankle latching member can be divided into two parts and bent using a hinge with a stopper, or a part of an ankle latching member can be attached or detached, or an ankle latching member can be divided into multiple parts. In addition, the ankle hooking member can be accommodated on the back side of the seat member by fitting the divided portions into a stretchable structure (telescopic structure).

According to the first aspect of the present invention, the user can sit down and take a predetermined posture, without imposing an unreasonable burden on the user's body and without restraining the body unnecessarily. Lumbar vertebrae can be easily corrected.
Also, it is easy to use even for users who are disabled, and can easily take a corrective posture such as lumbar vertebrae.
In addition, since the present invention has a simple structure and is easy to use, the lumbar vertebra can be corrected even at home. Moreover, the chair for treatment of low back pain according to the present invention can perform treatment having an effect similar to the traction effect on a patient with sciatica. In addition, the chair for treating low back pain according to the present invention can be used as a chair for preventing low back pain. In addition, there is a case in an effective Oite like to correct pelvic not limited to back pain.
Furthermore, the height can be adjusted according to the physical characteristics of the patient to be used.

  Hereinafter, an embodiment of a chair for treating low back pain according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an overall configuration of a low back pain treatment chair according to an embodiment of the present invention. FIG. 2 is a side view showing a state where a back pain patient is seated and treated on a back pain treatment chair according to an embodiment of the present invention. FIG. 3 is a plan view of FIG. FIG. 4 is a front view of FIG.

  In FIG. 1, a chair 1 for treating low back pain to which the present invention is applied includes a seat 2 (seat member) where a hip is located when a user is seated, a flat plate 3 (leg member) that supports the seat 2, and this Four legs 4 (leg members) for supporting the flat plate 3, a backrest portion 6 on which a seated user's back is located, two beams 7 (leg members) connected to the legs 4, and this beam 7 and an ankle retaining member 5 suspended from the arm 7.

The seat 2 is a flat plate. The seat 2 has a home-base hexagonal shape in plan view. This seat has a shape that narrows toward the front. That is, two portions of the rectangular corners in front of the rectangular flat plate are cut off. When the patient is seated on the seat 2 of the low back pain treatment chair 1, the thigh does not hit the corner of the flat plate due to the notched portion. Therefore, it is easy to bend a foot. The seat 2 may be a saddle shape of a bicycle.
A semispherical concave portion 13 opened downward is provided at a substantially central position of the bottom surface of the seat 2.

  The flat plate 3 has substantially the same shape as the seat 2 and has a larger area than the seat 2. A hemispherical recess 14 is provided at a substantially central position on the upper surface of the flat plate 3. Further, a groove 12 having a U-shaped cross section is provided on each of the left and right side surfaces of the flat plate 3.

  The back pain treatment chair 1 is configured symmetrically in front view. Hereinafter, the left side will be described. The right side has the same structure as the left side.

The leg 4 is composed of a long leg 4A as a front leg and a short leg 4B as a rear leg. Each of the long legs 4A and the short legs 4B is formed of a bar having a square cross section. The short leg 4B is fixed to the position of about 1/2 of the long leg 4A in the length direction so as to support the long leg 4A obliquely. That is, the front leg (long leg) 4A and the rear leg (short leg) 4B are both inclined in a side view and have a triangular shape. And the backrest part 6 which consists of board | plate materials is being fixed to the upper end of this long leg 4A. In addition, the bar is diagonally cut off and formed into a flat surface at the lower end of the long leg 4A and the lower end of the short leg 4B so that the back pain treatment chair 1 can be placed on a horizontal floor.
The side surfaces of these long and short legs 4A and 4B are respectively provided with slits 10 penetrating in the left-right direction of the back pain treatment chair 1 and extending in the length direction of both legs 4A and 4B.

  The concave portion 13 of the seat 2 and the concave portion 14 of the flat plate 3 are arranged to face each other vertically. A single metal ball 8 is rotatably accommodated between these recesses 13 and 14 and between them. This is the ball joint structure. The diameter of the ball 8 is larger than the sum of the depths of the recess 13 of the seat 2 and the recess 14 of the flat plate 3. For this reason, a predetermined gap is generated between the seat 2 and the flat plate 3. Accordingly, the seat 2 is supported by the ball 8 so as to be swingable, but comes into contact with the flat plate 3 when tilted at a certain angle. For this reason, the swing angle is not increased more than necessary.

  Two bolts 11 are inserted through the two slits 10 provided on the side surfaces of the two legs 4A and 4B from the outside toward the inside. And the front-end | tip part of the inserted two volt | bolt 11 protrudes inside, and the front-end | tip part of the protruded volt | bolt 11 is abutted on the bottom part of the groove | channel of the flat plate 3. FIG. That is, one side of the flat plate 3 is supported by two horizontally extending bolts 11 in the front and rear direction. Further, when the back pain treatment chair 1 is placed on a horizontal floor, the bolt 11 is inserted into the slit 10 at the same height from the floor so that the seat 2 is horizontal to the floor. The height of the seat 2 can be adjusted by the position where the bolts 11 are inserted through the slits 10.

  A beam 7 is fixed between the long leg 4A and the short leg 4B fixed to the long leg 4A so as to be parallel to the floor. This beam 7 is formed of a bar having a square cross section. One end of the beam 7 is fixed to the front leg 4A and the other end is fixed to the rear leg 4B, for example, with screws. A suspension bolt 9 shorter than the height of the beam 7 is inserted at a substantially central position in the length direction of the beam 7 so as to protrude downward vertically with respect to the beam 7. The head of the bolt 9 protrudes from the upper surface of the beam 7.

The ankle hooking member 5 is provided at a position lower than the seat 2. The ankle retaining member 5 is formed as a single bar as a whole by one column part and two cylindrical parts. Two cylindrical portions are connected to both ends of the one cylindrical portion. Both ends of the ankle retaining member project outward from the seat 2 by the same length as the width of the seat 2. The overhanging length is long enough for the user to sit on the back pain treatment chair 1, put both knees on the floor and bend the legs, and hang both the ankles.
Specifically, the cylindrical portion has a length substantially the same as the width of the seat 2 below the seat 2 and is fixed. Male screws of a predetermined length are formed at both ends of the cylindrical portion. And the internal thread of the predetermined length is also formed inside two cylindrical parts. And a cylindrical part is screwed in and connected to both ends of this column part, and it becomes the ankle latching member 5 which is one bar.
Adjacent to the portions where the female threads of both cylindrical portions of the ankle retaining member 5 formed in this way are formed, holes are provided through the cylindrical portions up and down.

The projecting hanging bolt 9 is loosely inserted into a hole penetrating vertically in the cylindrical portion of the ankle retaining member 5. A nut is screwed into the suspension bolt 9 so as to come into contact with the lower end of the ankle retaining member 5. In the ankle retaining member 5, when the back pain treatment chair 1 is placed on a horizontal floor, the screwing amounts of both nuts are adjusted so as to be horizontal to the floor.
The height of the ankle retaining member 5 can be adjusted by the screwing amount of the nut.

  In the back pain treatment chair 1, when the back pain treatment chair 1 is placed on the floor, the length of the leg is set so that the seat 2 is 20 cm to 40 cm high from the floor. . The position of the ankle retaining member 5 is designed to be 0 cm to 30 cm high from the floor. The projecting length of the ankle retaining member 5 is designed to be 10 cm to 15 cm. The back width of the back pain treatment chair 1 is designed to be 30 cm to 50 cm. The front width of the back pain treatment chair 1 is designed to be 5 cm to 20 cm.

The seat 2 is made of wood or steel. A cushion may be provided on the surface of the seat 2 using a urethane material or the like. Further, the upper surface of the seat 2 may be provided with a slip stopper for the concave and convex grooves extending in the lateral direction.
About the said leg 4, a long leg and a short leg can also be made into a folding structure. In this case, for example, the long leg and the short leg may be connected by a hinge with a stopper, and the beam 7 may be supported by a removable bolt.
Further, a cushion may be provided on the surface of the ankle retaining member 5 using a urethane material or the like. Moreover, you may connect with the hinge with a stopper, without the cylindrical part and column part of the ankle latching member 5 screwing together with a screw. If it is connected by a hinge with a stopper, the ankle hooking member can be folded on the back side of the seat.

  Next, a procedure for treating low back pain using the low back pain treatment chair 1 having such a configuration will be described with reference to FIG.
