Description

Multi-axis Foot and Ankle Training System

The present invention relates to a training device, and more particularly to a multi-axis foot and ankle training system.

The ankle joint is a highly mobile joint. When the ankle joint mobility is poor and limited, it will affect other adjacent joints and easily cause sprains and even walking posture. Therefore, strengthening the stability of ankle joint mobility is one of the common exercises in rehabilitation.

For example, the utility model patent publication number CN211215234U of the People's Republic of China discloses a foot and ankle muscle strength training device, which includes a rectangular base, two fixed blocks spaced apart on the base, two connecting rods obliquely pivoted on the fixed blocks, two foot pads pivoted on the upper ends of the connecting rods, and two springs respectively fixed on the connecting rods and one end of which is fixed to the base.

During training, the front soles and heels of both feet step on the front and rear ends of the pads in turn, and the springs are compressed to generate training resistance to train the ankle joint. However, the aforementioned ankle muscle training device can only train the ankle joint in a single axis, so the effect of improving the multi-directional mobility of the ankle joint is relatively limited.

Therefore, the purpose of the present invention is to provide a multi-axis ankle training system that can train the ankle joint in multiple directions.

Therefore, the multi-axis ankle training system of the present invention is suitable for operation by a user. The multi-axis ankle training system includes a support unit and an ankle training unit.

The support frame unit comprises a base and a bracket arranged on the base. The bracket has a telescopic tube which can be telescoped along a top-bottom direction, and an armrest which can be rotatably and adjustably arranged on the telescopic tube and is used for the user to hold.

The foot and ankle training unit is arranged on the base and includes two pedal devices and a second resistance group. The pedal devices are arranged on the base at intervals along a left-right direction substantially perpendicular to the top-to-bottom direction. Each of the pedal devices has a first resistance group arranged on the base, and a pedal group arranged on the top side of the first resistance group and used for the user's foot to step on. The first resistance group has a lower seat arranged on the base, an upper seat arranged on the pedal group, a universal joint connected between the upper seat and the lower seat, and a first resistance member that can be compressibly arranged between the upper seat and the lower seat and used to provide a pedal resistance to the pedal group. The upper seat can rotate relative to the lower seat with the universal joint as the center. The second resistance group is used to provide a training resistance to the pedal devices and has a plurality of detachable resistance ropes.

The effect of the present invention is that the upper seat can rotate relative to the lower seat with the universal joint as the center, and the resistance provided by the first resistance member and the second resistance group to the pedal devices, so that the present invention has the effect of multi-directional training of ankle joints. At the same time, the resistance ropes of different diameters or quantities can be replaced to change the training resistance and increase the training intensity. In addition, the user can adjust the height and angle of the handrail according to his or her height or posture, so that the present invention can be operated more stably with a correct posture, and the training effect is better.
