Description

[0001] Apparatus for ankle joint exercise [0002]

More particularly, the present invention relates to an ankle pump exercise device that transmits the power of a speed reducer motor to a shaft gear using a chain or a belt and uses a moving member that rises in accordance with rotation of the shaft gear, And a shock absorber capable of automatically lifting the foot of the exerciser at a predetermined height and capable of mitigating the impact applied to the foot of the fallen exerciser while the distance of the shock absorber An adjustable ankle pump exercise device.

The ankle pumping exercise is an exercise method based on the theory of ankle pumping movement of the eminent non-medical natural healing medicine expert of Japan, and it lifts the leg and the Achilles tendon area of the back of the ankle by the leg weight to the pumping roll, It promotes circulation, and it is a bodym that greatly helps to treat diseases.

These ankle pumping exercises require the pumping rolls to be placed on the bedding and then the athlete must lift the legs directly before dropping them. Therefore, the athlete who is poor in abdominal muscles or weak in the lower body can not perform several times, There is a problem that can not be sustained. Even if the athlete supports the physical strength, if the pumping exercise is performed for about 10 minutes, the user frequently takes the sleep naturally and often can not continue the pumping exercise for the desired number of times.

An ankle pumping device capable of lifting the legs automatically so as to obtain the exercise effect without lifting the legs directly by the athlete has been developed. The ankle pumping device is provided with various means such as a cylinder, a wire, So that the pump motion can be continued by dropping it.

However, in the conventional ankle pumping apparatus, noise and vibration are generated when the gears are mutually engaged and separated from each other, the wear of the gears is rapidly advanced, and the durability of the apparatus is lowered. And difficulty in repairing the system due to a complicated configuration.
