Abstract

A motorized guidance exercise apparatus for human muscle development is provided. The apparatus comprises an electric motor, a drive guidance assembly secured to the apparatus and to the motor, a headboard secured to the guidance assembly, an assistance and resistance force device secured to a limb or a torso of the human body, the limb or the torso positioned proximate the headboard, at least one force sensor to determine the effort expended by the human muscle to move the assistance and resistance force device, and wherein energizing the motor actuates the guidance assembly to induce a motion in the headboard, wherein the headboard is engaged by the limb or the torso and the assistance and resistance force device is moved by the limb or the torso, thereby guiding the limb and the muscle through an exercise movement with tactile feedback.

Claims (15)

1 . An isometric, dynamic isotonic concentric and dynamic isotonic eccentric motorized guidance exercise apparatus for human muscle development comprising:

at least one electric motor, said at least one electric motor including an output shaft;

a drive guidance assembly, said drive guidance assembly secured to said exercise apparatus and connected to said at least one electric motor, said drive guidance assembly includes a bar, said bar secured between said at least one electric motor and a handle of a weight bench;

at least one tactile feedback interface member, said at least one tactile feedback interface member is a headboard of said weight bench and said headboard is secured to said drive guidance assembly at said handle;

an assistance and resistance force device, said assistance and resistance force device configured to be secured to a limb or a torso of the human body, the limb or the torso positioned proximate said headboard;

at least one force sensor, said at least one force sensor calibrated to determine the effort expended by the human muscle to move said assistance and resistance force device; and

wherein energizing said at least one electric motor actuates said drive guidance assembly, said at least one electric motor induces a linear motion in said bar and said handle to raise and lower said headboard relative to said weight bench, wherein said headboard is configured to be engaged by the limb or the torso and said assistance and resistance force device is configured to be actuated by the limb or the torso.

2 . The exercise apparatus as recited in claim 1 , wherein said headboard includes said at least one force sensor.

3 . The exercise apparatus as recited in claim 1 , wherein said at least one force sensor includes:

at least one force plate;

a support plate;

at least one force gauge, said at least one force gauge including at least one force gauge plunger;

at least one guide rod; and

at least one compression spring.

4 . The exercise apparatus as recited in claim 1 , wherein said assistance and resistance force device is at least one weight plate of a weight stack, said at least one weight plate configured to be connected by a cable to the limb or the torso of the human body.
