Description

[Detailed description of the invention] (a) Purpose of the invention (field of industrial application) This invention relates to an exercise device for strengthening and training the lower limbs.

(Conventional Known Technology) As a conventionally known technology, the foot flexion/extension exercise device shown in the invention of Utility Model Publication No. 58-45727 uses a hinge type foot plate for both feet arranged in parallel on a base plate. It is pivoted so that it can be opened and closed vertically, and an elastic body is interposed between the plate and the base plate to constantly apply elastic force in the expansion direction, and by stepping on the foot treadle, vertical movement similar to stepping motion is achieved. This is what we do. Therefore, the only effect that can be expected is through bending and stretching movements involving the toes, ankles, and joints of the legs.

By the way, the most effective stepping exercise is the movement of the soles of the feet, especially the stimulation of the so-called potholes, which are the areas where the acupuncture points gather. This is because the flexor digitorum longus tendon and flexor pollicis longus tendon, which are representative of the quadratus plantaris muscle that forms the sole of the foot, form the base of the foot, and are connected to the tibial nerve that runs along the tibia, which supports the lower limb. The lateral plantar nerve is also subdivided at the base of the foot, and has many blood vessels. Stimulating very important parts of the body in this way to train muscles and promote blood flow is most important for maintaining health, but the above-mentioned ideas have no effect in this regard. .

Next, the lower limb training exercise device shown in Utility Model Publication No. 54-23420 is horizontally mounted on a base, a rocking plate is swingably attached to the shaft rod, and a spring body is interposed between the plate and the base. A footrest is provided on the upper surface of the rocking plate, and a large number of anti-slip and stimulating protrusions are provided on the footrest, but the sole of the foot is originally curved upward at the center. Therefore, even if the foot rest is curved to match the curvature of the sole of the foot, the projections will stimulate the entire surface of the sole excluding the foot. The present invention does not have a structure that stimulates the sokudo fumazu.

(Problems to be solved by this invention) In order to improve the above-mentioned drawbacks, in this invention,
An arcuate notch is provided at the center of the inner side of a pair of foot plates that are swingably provided on the base plate, a vibrating body is provided between the base plate and the foot plate, and a part of the vibrating body is exposed from the notch. This problem is solved by making it possible to perform foot stepping movements while providing stimulation to the foot of the foot.

(B) Structure of the present invention (Means for solving the problem) Receiving parts 2, 2 each consisting of a concave part with an arcuate cross section are provided on both sides of the base plate 1 at an appropriate interval, A pair of foot plates 4, 4 each provided with notches 3, 3 are provided with convex portions 5, 5 having an arcuate cross section that engage with the receiving portions on the lower surfaces of each of the pair, and the foot plate is swingable about the portions as fulcrums. A spring 6 is interposed between both rear sides of this foot treadle and the base plate.

A vibrating device is attached to the foot pedal device configured as described above.As an example, a cylindrical vibrating body 8 molded from an elastic material is rotatably attached to both ends of the vibrating shaft 7, and the vibrating body is A part of the vibration shaft protrudes from the notch of the foot plate, a storage part 11 for a small motor 9 is fixed to the center of the vibration shaft, a weight 10 is eccentrically fixed to the end of the motor shaft, and the vibration shaft has a lower end with a base. It is supported by the upper ends of support rods 12, 12 made of elastic material fixed to the plate.

Next, to explain another vibrating device, convex vibrating bodies 14, 14 molded from an elastic material are fixed to the upper surfaces of both ends of the vibrating plate 13, and the vibrating bodies are attached to the notches of the footplate.
A pair of elastic materials having a storage part 15 housing a motor 9' fixed to the central lower surface of the diaphragm, a weight 10' eccentrically attached to the motor shaft, and a lower end fixed to the upper surface of the base plate. Made of support rods 16, 16
Support at the upper end of. The motor is operated by a battery 17.

(Function) To explain the function of the present invention, when the motor 9 is activated by operating a switch (not shown) at the same time as both feet are placed on the foot treadle 1 and the foot is stepped, the weight 10 is fixed to the motor shaft. Because of this, the small motor vibrates significantly up, down, left and right. This vibration is transmitted from the vibration shaft 7 to the vibrating body 8. In another example, the vibration of the motor is transmitted to the vibrating body 14 via the vibrating plate 13. Therefore, the sole of the foot receives moderate stimulation from the vibrating body exposed through the notch 3 during the stepping motion. Since springs 6 are attached to the front and rear sides of the foot treadle, the foot treadle 1 swings using the protrusion 5 on the lower surface as a fulcrum when stepping. The spring is stretched against its elasticity, so a strong force is required at the toe, and when force is applied to the heel, the front spring is stretched against its elasticity, so a strong force is required at the heel. Therefore, stepping exercise can be performed more effectively.

(Embodiment) To describe the embodiment of the present invention in detail with reference to the drawings, receiving parts 2, 2 each consisting of a recessed part with an arc-shaped cross section are provided opposite each other at appropriate intervals on the base plate 1, and an arc-shaped notch 3 is provided in the inner center part. , 3 are provided on the lower surfaces of each of the pair of foot treads 4, 4, each having a convex portion 5, 5 having an arcuate cross section and engaging with the receiving portion.
Attach the upper end of the spring 6 to the lower surface of both the front and rear sides of the foot treadle so that it can swing freely using this part as a fulcrum,
The lower end of the spring locks onto the base plate. In order to attach a vibrating device to the foot pedal device having the above configuration, in one example, a cylindrical vibrating body 8 molded from an elastic material is rotatably attached to both ends of the vibrating shaft 7, and a part of the vibrating body is exposed through the notch. let Therefore, no severe friction occurs when stimulating the soil. A motor storage part 11 is fixed to the lower surface of the center of the vibration shaft, a small motor 9 is installed therein, and a weight 10 is eccentrically attached to the end of the motor shaft.
The lower end of the vibration shaft is supported by the upper ends of support rods 12, 12 made of elastic material and fixed onto the base plate 1. Although not shown in the drawings, small stimulation projections may be provided on the outer peripheral surface of the vibrating body 8.

Next, another embodiment of the vibrating device will be described. Convex vibrating bodies 14, 14 molded from an elastic material are fixed to the upper surfaces of both ends of the vibrating plate 13, and the vibrating bodies are exposed through the notch 3, and the vibration A housing part 15 containing a motor 9' is fixed to the lower surface of the center of the plate, and a weight 10' is eccentrically attached to the end of the motor shaft.
A support rod 16 made of an elastic material whose lower end is fixed to the base plate 1,
The upper end of 16 supports the diaphragm. The motor is operated by a battery 17. Note that 18 in the drawing is a side plate for preventing the receiving portion 3 and the convex portion 5 from coming apart.

(C) Effects As explained in the section on function, this invention is very effective in strengthening ankle training because strong force is exerted on the toes and heel due to the action of the front and rear springs 6 during stepping movements. It stimulates the muscles and nerves in the soles of the feet, increasing blood flow and having great health benefits.

In the case of the present invention, since the vibrating bodies 8 and 14 stimulate the foot of the foot during the stepping motion, a synergistic effect is produced. The nerves distributed in the soil are one of the motor nerves and are also connected to the sciatic nerve. Therefore, it stimulates the various muscles and nerves that make up the soil, increasing blood flow, improving motor function, and strengthening not only the lower limbs but the whole body. Also, standing on the swinging footboard has excellent effects such as developing a sense of balance.
