The present invention relates to an ankle pump exercise device, and more particularly, to an ankle pump exercise device capable of automatically performing an ankle pump exercise.

In general, ankle pump practice refers to an exercise method in which a pumping operation is performed by momentarily stopping the operation of entering and falling a foot to a predetermined height. Specifically, towels were put on bamboo or logs of about 30 cm in length and 6 cm to 10 cm in diameter, and the legs were rolled up while sitting or lying down, and the towels were wound on the floor corresponding to a portion adjacent to the calf side from the achilles tendon of the body. Lay bamboo or logs. The knees of one leg are removed and the feet are lifted to a height of about 20 cm to 30 cm in a flat state, and then the legs are momentarily dropped without force, and the towel of the Achilles tendon area is hit by a log wound.

At this time, the legs hit the log, the toes are naturally stretched and the Achilles tendon is contracted, and when the feet are raised again, the toes are naturally stretched upward. While repeating this method, it is possible to repeat the relaxation and contraction of the muscles of the calf, and this pump action can effectively promote blood circulation.

Ankle pump exercise was first invented by a Japanese person named "Inagaki Amisakura", who suffered from kidney disease and diabetes since he was a child, and the leaves swaying in the wind while trying to find a healthy way to live in nature. It is said that he invented an ankle pump exercise method.

Ankle pump exercise is to smoothly circulate blood, and can prevent the accumulation of waste by promoting blood circulation, preferably can also remove the waste accumulated in the blood. Ankle pump exercise is therefore excellent for diseases and prevention of blood circulation, e.g. diabetes, vision recovery, cirrhosis, hypertension, gout, heart attack, constipation, diet back pain, nerve palsy, enlarged prostate, itching, hemorrhoids, athlete's foot It is known that it is effective for long cleaning and the like.

A practitioner (practicer) who wants to perform the ankle pump exercise should lift the foot directly and drop the leg by pulling power on the lifted foot. However, if the practitioner can't lift his leg, such as when he or she is undergoing rehabilitation, he can't do ankle pumping alone.

In addition, the practitioner must be properly trained to perform the ankle pump exercise in order to perform the ankle pump exercise properly. However, in most cases, learners must learn by themselves without the guidance of a third party, so implementers are not sure that their method is the right one, and in the long run it may adversely affect the implementer.

Referring to FIG. 2, the ankle pump exercise device 100 according to the first embodiment includes a base 110 having a predetermined size, a driving device 120, a rotating shaft 130, an intermittent transmission unit 140, a cushion, and the like. It includes a leg support 150 for lifting and falling ankle support 160 having a cushioning function.

The base 110 is horizontally disposed on the ground, and the driving device 120 and the rotating shaft 130 are arranged side by side on the base 110. A buffer hole 112 is attached to the bottom of the base 110 to mitigate shock and impact noise generated by ankle pump movement.

The driving device 120 generates a rotational force by applying power from the outside, and the control unit 170 mounted on the base 110 controls the power and the operation mode supplied to the driving device 120.

 The rotating shaft 130 is mounted on the base 110 in parallel with the axis of the driving device 120. Both ends of the rotary shaft 130 are supported by the shaft support 132, the shaft support 132 includes a rolling bearing or a journal bearing and the like to assist the rotation shaft 130 to smoothly rotate.

The intermittent transmission unit 140 includes a first gear 142 and a second gear 144, the first gear 142 and the second gear 144 is selectively engaged to transmit the rotation intermittently. The first gear 142 has a diameter smaller than the diameter of the second gear 144. In addition, the first gear 142 is not all formed around the teeth, but has a partially missing area, the second gear 144 is all formed around the teeth. Accordingly, when the parts having the gear teeth formed contact with each other, the rotation shaft 130 is rotated and the rotation is blocked by the part where the gear teeth are lost.

The leg support 150 is fixed to the rotating shaft 130 by welding. The other side of the leg support 150 is coupled to the ankle support 160 configured as shown in FIG. Accordingly, when the rotation shaft 130 is rotated, the ankle support 160 rotates together to naturally lift the legs of the exerciser placed on the upper portion thereof.

The ankle support 160 is coupled to one side of the leg support 150, the bottom is composed of at least one cushion pad 162 is attached to the rubber sheet 164 to absorb the shock mitigation and shock sound is stacked, the The leg support 150 stops and supports the ankle portion of the leg when it falls down from the upper position to the bottom at a high speed to the ankle pump motion by stopping the ankle.

At this time, the cushion pads 162 are adapted to join a plurality of cushion pads stacked on top of the lowermost cushion pad by a so-called "velcro fastener". That is, it is possible to adjust the height of the entire ankle support 160 to adjust the strength of the ankle pump movement. Selective stacking of such cushion pads 162 is to control ankle pump momentum. In addition, the upper surface of the cushion pad 162 coupled to the top includes a curved surface formed with a curvature of 6 ~ 15cm, the curved surface is directed upwards.

Hereinafter, a process of performing an ankle pump exercise using the ankle pump exercise mechanism 100 according to the first embodiment will be described.

Referring to FIG. 3A, the driving device 120 rotates in the counterclockwise direction, thereby rotating the first gear 142 and the second gear 144. Since the first gear 142 is meshed with the gear teeth, the second gear 144 may rotate in conjunction with the first gear 142. The rotation shaft 13 rotates in the clockwise direction by the rotation of the second gear 144, and the leg support 150, which is broken on the rotation shaft 130, is also rotated to lift the ankle support 160, thereby placing the leg on the upper portion thereof. Lift it up.

Referring to FIG. 3B, when the gear toothed portion of the first gear 142 is out of the second gear 142, the rotational force is not transmitted to the second gear 144. The rotary shaft 130 that lost the rotational force is rotated at a high speed in a counterclockwise direction due to the weight of the ankle support 160 coupled to one side, the leg support 150 is also dropped. Because the leg support 150 falls, the legs that lose their support force fall to the top of the base 110 together with the ankle support 160. Therefore, the ankle portion is supported by the ankle support 160 and the ankle is stopped on the base. In this process, ankle pump exercise is performed.

The controller 170 may control whether the driving device 170 is operated, the number of rotations, and the like, and may control the number of times of the ankle pump exercise and the exercise time by the control. The performer may perform the exercise of one leg after the exercise of one leg by using the ankle pump exercise device 100. In addition, by placing the two ankle exercise device 100 in parallel can perform ankle exercise of both legs at the same time.
