Abstract
A direct drive resistance system for exercise machines having a weighted moment arm that is lifted and lowered by a lifting moment arm and lifting component, which is moved by a force transfer assembly, which is operatively connected to a rotary component of an exercise machine, such that when the exercise machine is activated the force transfer assembly, the lifting moment arm, the lifting component and the weighted moment arm move concurrently to create a resistance force to the motion of the exercise machine.
Claims6
A direct drive resistance system for exercise machines comprising:
- a) a structural support frame;
- b) a weighted moment arm pivotably connected to the support frame;
- c) a lifting moment arm pivotably connected to the support frame;
- d) a force transfer assembly pivotably connected to the support frame and operatively connected to the lifting moment arm;
- e) an adjustable position lifting component movably mounted on the lifting moment arm;
- and
- f) a latching and unlatching mechanism for securing the adjustable position lifting component to a position on the lifting moment arm;
- wherein the weighted moment arm, the lifting moment arm, the adjustable position lifting component, and the force transfer assembly are operatively engaged with each other such that the lifting moment arm and the adjustable position lifting component lifts and lowers the weighted moment arm during operation of the system.
