ABSTRACT:
The present invention provides a system for transmitting a biasing force created by a force generating component to a load remote from the force component. the system includes a first elongated flexible element having a first end and a second end, the first end of the first flexible element being connectable to the force generating component, and a second elongated flexible element having a first end and a second end, the first end of the second flexible element being connectable to the load. A force modifying member rotatable about a fixed axis is provided and includes first and second outwardly facing surfaces of predetermined lengths which curve about the axis. The second ends of the elongated flexible elements are connected respectively to the first and second surfaces at one end of the surface, wherein the fexible elements are operable to be wound or unwound on the respective surfaces as the member rotates about the axis. The first flexible element produces a force moment about the axis in a first direction biasing the force modifying member into rotation in the first direction. The second element exerts a resultant biasing force on the load. The first and second surfaces are dimensioned such that rotation of the member about the axis in the first direction causes one of the elements to be wound onto its respective surface as the other element is unwound from the its respective surface top vary the force moments about the axis, to render the biasing force on the load generally more uniform.
