Description

Exercise equipment for pelvis and knee The present invention relates to a pelvic and knee exercise device, and more specifically, to an exercise device that assists the movement of elderly people or patients with limited lower body mobility, thereby enabling them to easily perform pelvic and knee exercises. As prior art regarding exercise equipment for the elderly or patients with limited mobility of the lower body, Korean Patent Publication No. 10-2019-0023966 (published on March 8, 2019, hereinafter referred to as 'prior art') "Lower body exercise equipment" is disclosed. The aforementioned prior art comprises: a pair of vertical supports adjustable in length; a horizontal support adjustable in width and fastened to the upper part of the vertical supports; two motors fixedly installed on the horizontal supports and equipped with a remote control receiver; a plurality of rope winding rollers installed to be interlocked with the rotation axes of the motors; a rope installed to be raised and lowered when the rope winding rollers rotate, and equipped with a means for fixing a user's leg at the bottom; a support member coupled to the lower part of the vertical supports; and a remote control for controlling operations including the raising and lowering of the ropes; wherein the remote control controls operations including the raising and lowering of the ropes through receivers fixedly installed inside the two motors, the rope winding rollers form a set of two, and a pair of rope ends are fixedly installed in a separated state so as not to entangle with each other, and when the rope winding rollers rotate, the winding or unwinding operation of a pair of ropes occurs simultaneously, and the rotation axes of the motors are installed protruding forward of the horizontal supports or the rotation axes of the motors are installed below the horizontal supports The present invention relates to a "lower body exercise machine characterized by being installed," and provides a lower body exercise machine that has a simple structure and can be easily used not only by the general public but also by the elderly, infirm, and patients with limited mobility. However, the aforementioned prior art is not convenient to use because the user's ankle must be hooked onto the ankle fixation means, and there is a problem that the exercise effect is reduced because the range of motion of the joint is not wide when the leg is moved up and down repeatedly.
