ABSTRACT:
The present invention is directed to a complete body strengthening and stretching apparatus which relies on passive motion provided by a drive mechanism to direct the movement of the back, legs, arms and torso. The apparatus may include a support frame including a base adapted to rest on a floor and provided with a body support for supporting the user in a seated position. In the preferred embodiments, the support frame may include a back rest and seat, or further a body rest and a leg support surface for supporting and working of the lower body. An exercise bar is positioned in conjunction with the frame and is grippable by the user for stretching and exercising the upper body by means of movement of the exercise bar. A linear actuator is coupled to the frame and operates to cause movement of the exercise bar for imparting passive motion to the arms and upper body of the user. The exercise bar is operatively coupled to the linear actuator which includes a drive motor for providing a directional driving force to said linear actuator for at least raising and lowering of the exercise bar. There may also be associated with the apparatus a control system coupled to the linear actuator for translating control signals to control the direction or other aspects of the actuator operation. The bar may also be made to impart rotational motion to the upper body. In an embodiment of the invention, the frame may include an exercise seat and linkage mechanism coupled to the linear actuator and a leg support and extension mechanism so that extension of the exercise bar and the resulting raising of the arms above the head of the user corresponds to bending of the user's legs as in a deep knee bend or conventional squatting exercise. A control system may be used in conjunction with the control interface or preset to control the direction, speed, extension of the arms or legs or other aspects of operation. Adjustment of the linear actuator operation controls the degree and speed of extension and contraction of the various body parts by extending the actuator at a set speed and only to a predetermined stop point. Alternatively, the user manually controls the degree of extension through a hand- or foot-operated controls.
