Description

  The electric chair of the present invention is related to the peripheral patent of JP 2001-327626 filed earlier by the present applicant, and is an exercise device for training the sense of balance of the legs and hips and also a health device for the treatment of low back pain. .

  The balance feeling and the strengthening of the legs and legs are the basic problems of various sports, but no suitable exercise equipment has been found in the past. For example, sports such as surfing, snowboarding, skiing, and skating directly require balance-sensitive reflexes. However, not only these sports, but also tennis and baseball catching, and a basket, volleyball and soccer ball competing against each other, a strong and agile movement is required. In addition, for the treatment of low back pain and rehabilitation for the elderly and illness, it is necessary to correct the lumbar facet joint and strengthen the muscles of the psoas muscle.

As an instrument for balance sensation training and leg / hip training, there is Patent Document 1 previously filed by the present applicant. This is an effective foot and hip training device that incorporates a motion that stretches the muscles around the Achilles tendon by combining longitudinal motion with vertical motion, and it is difficult without a handrail until it gets used.
JP 2002-315846 A

As an exercise tool that imparts a twisting motion to the lower body against such a linear weight shift, a health device that exercises the legs and hips by riding a rotating disk is effective. Patent Document 2 was previously filed by the present applicant. Among these, there are devices that balance on an inclined disk, devices that rotate electrically, devices that can be exercised while sitting on a chair, etc. It has already been effective.
JP 2001-327626 A

  However, in terms of prevention and treatment of lower back pain, correction of the lumbar spine and reinforcement of the psoas major muscle are required, and an exercise device that does not overwhelm is necessary. Is.

  Index therapy described in Japanese Utility Model Publication No. 7-30017 is generally used as a treatment for low back pain patients. This lumbar indexing device winds a belt around the patient's pelvis and indexes the legs downward. And, in order to open the lumbar facet joint, a large index force is required, so the lateral femoral skin nerve may be compressed and the patient's back pain may be warped and worsened.

Therefore, various prior arts have been proposed as low back pain treatment and prevention devices. The following Patent Document 3 and Patent Document 4 are exercise tools which are designed to raise a waist by lifting a leg placed on a table.
JP 2002-345869 A JP 2003-169818 A

Patent Document 5 is an apparatus in which a pad material is inserted inside a knee and pulled. In Patent Document 6 and Patent Document 7, when the inside of the knee is lifted, the ankle portion is saved so as not to rise.
JP 2002-301122 A Japanese Patent No. 3470106 JP 2001-178756 A

Further, Patent Document 8 and Patent Document 9 propose that a rocking device that imparts waist twist is also effective.
JP 2000-308661 A JP 2001-346847 A

However, any of the prior arts for low back pain is a painful treatment apparatus in which the legs are raised in a supine state that is difficult to operate by itself. One of the causes of low back pain is not only correction of the lumbar spine but also strengthening of the psoas major, which is connected to the mandible via the buttocks. Therefore, muscle strengthening around the heel is necessary, but the conventional apparatus has not taken any measures against this. And for back pain patients, there is a demand for warming up the waist as well as exercising. Although this has not been corrected, it has been shown that the treatment of low back pain with the waist warmed is effective, but there has been no treatment apparatus with such consideration in the past. In order to warm up, it is unsuitable to keep the moving waist directly in the stove, and the entire waist cannot be kept warm in the hood. In that respect, if the planar heating element of Patent Document 10 taken by the applicant of the present invention is attached, it is effective to keep only the waist during this exercise.
Japanese Patent No. 2671923

  Hereinafter, the electric chair of the present invention will be described in detail based on the drawings.

  The first embodiment is an invention relating to claim 1 and claims 3, 4 and 5, and is shown in FIG. FIG. 1 is an embodiment of an electric chair according to the present invention, in which (a) is a longitudinal sectional view of a device showing a wavy rocking means of the present invention, and (b) is a longitudinal section of a device showing a reciprocating rotating means of the present invention. (C) is a plan view of (b) cut along the AA plane.

  First, a description will be given with reference to (a) and (c) in FIG. The electric chair 1 according to the present invention sits on a chair 2 and exercises. The chair 2 of the present embodiment has a backrest part 3, an armrest part 4, and a seat part 5. The seat 5 is indispensable for the present invention, and is made of a rotatable disk or close to it. Further, the backrest part 3 and the armrest part 4 may rotate together with the seat part 5, or may be fixed independently of the rotation of the seat part 5 so as to twist the waist. .

  The material of the electric chair 1 of the present invention may be plastic or wood, but in the case of the present embodiment, it is mainly intended for hospitals and facilities, so that it does not wobble even if many people use it. It is made of metal. A column group 7 is erected on the base 6 at the peripheral edge of the lower surface of the disk-shaped seat 5 to be pivotally supported. In this case, the rollers 9a... 9a are pivotally mounted in the couplings 8. The column group 7 in this embodiment is composed of four columns 7a, 7b, 7c, and 7d. In the column group 7, the column 7a is the highest, and the columns 7b and 7d are half the height in the middle. 7c is made the lowest and has a height difference so that the seat portion 5 is inclined at an inclination angle θ. In addition, the height difference of the four support | pillar groups 7 can also make two support | pillars high and can make two support | pillars low. The reason for inclining so as to have a height difference is that the column group 7 can be made the same height, the base 6 can be inclined, and the inclined shaft can be rotated by a universal joint.

  The base 6 to which the column group 7 is attached is connected to the lower motor 10a. On the other hand, the disk 5 of the seat portion pivotally attaches a shaft 11 to the center of the lower surface, and this shaft 11 is fixed by a lower frame 12. The seat portion 5 is fixed to the frame body 12 so as to face the front surface by a detachable pin 13 on the back surface, and can be fixed so that the chair 2 does not turn. Accordingly, when the motor 10a is electrically rotated, the chair 2 is safely supported by the shaft 11, but the lower column group 7 having a height difference rotates on the lower surface of the disk. Therefore, the seat portion 5 swings so that the bottom surface undulates while facing the front. Conventionally, there has been no exercise equipment that gives such a gentle stimulus to the buttocks. However, this wavy rocking means is effective for strengthening the muscles of the buttocks related to back pain.

  A motor 10 b is connected to the lower column group 7 at the lower part. If it is desired to change the inclination angle θ of the disk 5 of the seat, in the case of the present embodiment, if the motor 10b is operated, for example, if the lowest column 7c is raised to the position of the highest column 7a, The intermediate heights 7b and 7d are increased by half at the same time so that they are all the same height. In addition, the change of the slide of the inclination angle θ by adjusting the height of the column group 7 is not limited to the present embodiment. Further, the operation method is not limited to the electric motor, and it can be performed manually. And the height difference can also be made to push up the column group with a cam.

On the other hand, the electric chair 1 of the present invention also includes reciprocating rotation means. Each mechanism is used as a means in the present invention because the embodiment shows only one mechanism, and there may be other mechanisms that match this means.
Hereinafter, description will be made with reference to (B) and (C) in FIG. A hydraulic machine 14 is provided in the lower frame 12 so that the upper elevating disk 15 can be pushed up. In the case of the present embodiment, the four lifting rods 16... 16 stand up through the base 6 and the hexagonal pyramid-shaped convex fitting portion is formed at the upper end of the raising rods 16. 17 ... 17 are attached. The convex fitting portions 17... 17 are detachably fitted to hexagonal pyramid concave fitting portions 18... 18 attached to the lower surface of the disk 5 of the seat portion.

  A roller 9b (coupling is omitted) is pivotally attached to the tip of the hydraulic machine 14 of this embodiment, and is not attached to the elevating disk 15. Therefore, the elevating disk 15 is integrated with the base 6 by the protruding rods 16... With the pin 13, the lifting disk 15 is pushed up with the chair 2 properly facing the front, and the seat 5 has a height difference with the convex fitting parts 17 ... 17 and the concave fitting parts 18 ... 18 fitted. It is released from the roller 9a on the supporting column group 7 and can be rotated in a horizontal flat state by the protruding rods 16 ... 16. The seat 5 is reciprocally rotated in the forward and reverse directions by an inverter 19 connected to the motor 10a.

  The rotation angle α can be freely changed. In addition, the rotation angle α is not a field where the angle is set in advance, but is directed to the front at first, then proceeds to 15 degrees and 20 degrees, and finally increases to 45 degrees, such as 45 degrees. You can make it easier for the elderly. The rotational speed can also be changed by a transmission (not shown). These switching operations can be performed in a manner suitable for the user with the operation panel 20 at hand while sitting on a chair. The electric chair 1 according to the present embodiment is configured to have both a wavy rocking means and a reciprocating rotating means.

  It is said that back pain should be stretched in a warm condition after taking a bath. However, no such device has been considered in conventional devices. In the case of the present embodiment, a planar heating element 21 is attached at a position where the lower back of the backrest portion 3 hits. The planar heating element 21 does not need to be provided with a thermostat, and can be set to a predetermined temperature of, for example, 50 ° C., and can move while warming the waist even if it is slightly separated.

  The second embodiment is an invention relating to claims 2, 5 and 6, and is shown in FIGS. 2 and 3, and FIG. 4 is shown for explanation. FIG. 2 is a longitudinal sectional view of an apparatus showing the bending and stretching movement means of the present invention in another embodiment of the electric chair of the present invention. FIG. 3 is a perspective view showing a state of a person who is bending and stretching. 4A and 4B are diagrams for explaining the human body. FIG. 4A is a diagram showing bones and muscles of the lumbar region, and FIG. 4B is a diagram showing the lumbar spine.

  The following description will be mainly focused on differences from the first embodiment. In FIG. 2, the electric chair 101 of the present invention includes a chair 102 and a disc-shaped seat 105. Since the electric chair 101 of this embodiment is mainly used for home use, it is made of an assembly-type plastic. Further, the column group is provided with a roller 109a at the upper portion of 107, and a shaft 111 is erected in the center. Further, the chair 102 is provided with a planar heating element 121.

  In this embodiment, a motor for adjusting the height of the column group is not provided, and the inclination angle is only constant. Further, no hydraulic machine is provided, and the lifting / lowering disk 115 is simplified to be moved up and down by the operation of the lifting / lowering switching rod 114. Although details of the up-and-down switching rod 114 are omitted, it is also possible to have a roller on the upper part and grip the entire surface of the up-and-down disk 115.

  In addition, as shown in FIG. 3, in the state where the person M is sitting on the chair 102, the lifting rod 122 is inserted inside the knee, and the bending / extension exercise means for raising the knee by operating the handle 123 is added. . At the time of this bending / extending movement means, as shown in FIG. 2, the chair 102 is fixed with the pin 113 so as to face the front. Since the fulcrum of the handle 123 is pivotally attached to the lower rear part, when the handle 123 is pulled, the knee is lifted and the thigh is pressed against the chest. Of course, this bending / extension movement can be implemented by a mechanism such as an eccentric cam attached around the rotation shaft to raise and lower the leg up and down like a red walker.

The operation of the above mechanism will be described with reference to FIGS.
FIG. 4 (a) shows human bones and muscles around the waist. 124 is the pelvis, and the lumbar spine 125 and the psoas major muscle 126 are mainly associated with low back pain. However, the psoas muscle 126 is connected to the mandible 127 from the buttocks to the crotch. Therefore, to relieve back pain, it is necessary to exercise the foot mainly on the buttocks, but this has been overlooked in the past. In addition, since an unreasonable gait is difficult for patients with low back pain, an easy buttocks exercise is suitable.

  FIG. 4B is an enlarged view of 125 lumbar vertebrae. In the treatment of low back pain, as can be seen in the conventional index treatment, the sacrum 128 is returned to the front as shown by the dotted line in FIG. 4B to widen the compression of the posterior 129 of the facet joint. For that purpose, it is more effective to bring the thighs closer to the chest side like a shrimp, rather than just pulling up and pulling up the legs like a conventional treatment instrument. The mechanism of this embodiment is preferable.

  The electric chair of the present invention can be widely used as a device for preventing and treating back pain, as a device for rehabilitation after illness and for the elderly with limited mobility, and as an exercise device for balance sense training of athletes. is there.
