Controllable Training and Rehabilitation Device

Abstract

A muscle training and physical rehabilitation device is disclosed. The device is controllable by liquid based resistive units. The liquid based resistive unit utilizes either smart magnetorheological (MR) liquid whose resistance to motion can be adjusted by electromagnetism or by proportional valves with various liquids whose resistance can be controlled by an electronic signal. The MR fluid resistive units comprises a rotor supported by a bearing inside a housing, a stator mounted together with the housing to the mounting plate, and the MR liquid that flows inside the cavity formed by the vane of the rotor and chamber of the stator. The MR liquid is controlled by the applied electromagnetic field to adjust the resistance according to the exerted toque.

Description

[0001]This patent application claims the benefit of, priority of, and incorporates by reference U.S. Provisional Patent Application Ser. No. 61616938, entitled “Full Body Controllable Training and Rehabilitation Device” by Alexandr Shkolnik filed on Mar. 28, 2012.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to an exercise equipment, and more particularly, to a dynamic resistance exercise device.[0004]2. Description of the Related Art[0005]Various training and rehabilitation devices are used by individuals at home or as public facilities in community. These devices are usually based on simple mechanical systems such as the gravity force from a stack of weights, elastic force from springs, etc, which provide the resistance subjecting to the movement of human body to strengthen the muscles. A lot of exercise machines are developed to train different portion of body, such as stationary bicycles, rowing machines, treadmills, ski ...

AI Technical Summary

Benefits of technology

[0007]Considering the shortcomings of the previously mentioned conventional training devices, there is a desire to provide a portable and controllable machine based on smarter resistance. It is also desirable for the resistance to be adjus...

Problems solved by technology

However, these conventional exercise machines usually only provide fixed resistive force due to the fixed gravity and fixed elasticity.

Also, most of these conventional exercise machines are not capable of changing resistance in real time.

In the middle of the training, the only way of changing the weight is stopping the training and changing the number of weights, the same situation is for the spring based devices, which is quite inconvenient for the users.

Even worse, the conventional devices have limited range of forces.

They cannot be used by a large population of users with different ages and differen...
