Biped walking is the greatest feature of the body that only human beings have, and therefore for many years because of the necessity of bipedal walking, the knee supports the weight from the body's knee to the head and constantly presses the knee joint.
In recent years, the life expectancy has increased, and with the progress of aging due to aging, the knee joint cartilage is compressed by the weight of the body and the weight of lifting for many years, and the knee joint cartilage becomes thin and the number of difficult walkers causing knee pain has increased dramatically. As the number of walks decreases, leg muscular strength gradually declines, making it impossible to walk, and many caregiver events leading to bedridden have occurred. Knee flexion and extension exercises with standing legs are difficult in the case of knee pain due to the weight of the knee joint. Therefore, in order to reduce the weight received indirectly by the knee, there are many cases of walking underwater using buoyancy in a pool or the like, but there is a problem that a person with difficulty in walking has difficulty in going to the pool.

    The present invention provides an exercise device that makes it easy to walk by advancing knee joint extension and lower leg traction muscle strength easily at home when the elderly begin knee pain and leads to difficulty walking. is there.

    According to claim 1 of the present invention, it is possible to arbitrarily fold the back raising portion by the latitudinal mechanism, and the inclination angle of the bed body is based on the worm wheel gear and the pair of worm gears directly connected to the rotating shaft fixed to the bed body. The leg extension muscle strength strengthening device in which the ankle retainer is disposed at the end of the bed main body.

    Further, according to claim 2 of the present invention, the ankle holder can be arbitrarily moved in the head side direction, the ankle holder is a semi-shoe-shaped, and the ankle holder can be rotated. Lower limb extension muscle strength strengthening device.

    Moreover, Claim 3 of this invention is a leg extension strength strengthening apparatus which provided the movable carriage which can slide to the said bed main body.

    According to a fourth aspect of the present invention, as a method of driving the bet body in an inclined manner, instead of the worm wheel gear and the worm gear, the bed body is driven by forward / reverse rotation of a worm guard reversible motor directly connected to a screw shaft. This is a leg muscular strength strengthening device that rotates a screw nut fixed to the bed so that the inclination angle of the bed main body can be arbitrarily changed.

    In the above state, the head side of the bed is tilted downward arbitrarily, and the sliding gravity is increased to perform a stronger pulling / bending / extending motion.

    The knee joint is extended, the knee cartilage is released from the compression, and the spread of the knee joint promotes the drainage of fluid from the periosteum and relieves knee pain.

      The bending and stretching movements at the horizontal position of the bed and the inclined position in the downward direction on the head side do not suffer from body gravity at the knee joint, and therefore do not involve knee pain due to weighting.

    By bending and stretching with traction, lower limb muscle strength, especially the quadriceps, is strengthened, and it becomes easy to lift the lower limbs during walking, leading to walking.

    The present invention has a simple device structure, simple operation, and can be easily used by elderly people at home.

The flexion and extension that extends the lower limbs to the original position indicates a state in which the knee can be exercised without gravity due to weight.

    FIG. 3 shows a state in which when the bed main body 1a is tilted with the buttocks on the movable carriage, it can be pulled with the gravity due to its own weight as a load. If the tilt angle is increased arbitrarily, the gravity load on the body increases and the traction force can be increased.

    Theoretically, if the back raising portion 1b is inclined to 90 degrees, the bed main body 1a can be inclined more than 90 degrees. Therefore, it can be performed in accordance with a selection method for maintaining the safety of the user although it is in an inverted fishing state.

    FIG. 4 shows the rotation of the worm gear 10 fixedly attached to the handle 2 of FIG. 1 to rotate the rotating shaft 8 fixedly connected to the worm wheel gear 9, thereby rotating the bed main body 1 a fixed to the rotating shaft 8. The mechanism which inclines as the fulcrum 3 of the axial direction of the axis | shaft 8 is shown.

    The ankle retainer 4 of FIG. 5 can be moved and fixed to the head side of the ankle retainer transfer base 5a according to the length of the lower limbs at the beginning of use, and can be rotated by the rotation fulcrum 5 according to bending and stretching. It shows the state that can move.

    The ankle retainer 4 of FIG. 6 is a semi-shoe-type in order to maintain a reliable holding force and safety for elderly people, and holds the upper side of the heel. The fastening buffer band 4a, the right side fastener fastening band 4b, the left side fastener fastening band 4c, and the outer periphery fastening band 4d are shown, and the ankle is held by the ankle holder 4 is shown.

    FIG. 7 shows a bed body in which a screw shaft 12 and a screw nut 13 connected to a worm geared reversible motor 11 fixed to a pedestal 14 are used in place of the worm gear 10, worm wheel gear 9 and handle 2 described in detail above. A mechanism fixed to 1a and inclined as a fulcrum 3 in the axial direction of the rotating shaft 8 is shown.
