LOWER EXTREMITY MUSCLE TRAINING STRENGTHENING DEVICE

摘要

PURPOSE:To strengthen the bending and extension of muscle by setting the turning center of a foot, pedal, and the turning center of a toe pressing onto a nearly same axis and maintaining a constant large torque for a certain time at the both edges of turn. CONSTITUTION:The height of an ankle pressing roller 22 is adjusted by loading an ankle onto a foot rest 21 so that the turning center C of a foot coincides with the turning center O of an arm. Though the selection of the normal and reverse revolution and the revolution quantity of the motor of a driving device can be controlled mechanically by a timer, etc., the initial set value is memorized by a microcomputer, and afterwards the operations are conveniently repeated according to the memory information. With the device in operation state, each optimum value of the bending angle A and extension angle B is set in sensible manners by the inting operation. The positions set by the setting operation are the turning terminal points Q and S, and at each position, the device stops for 2-3sec set by the timer. Further, turning is performed through the gentle operation within the range immediately before the stop, for example in 5-10 deg..
