Weightless traction system

A system for translating a constant load to an object requiring traction, comprising:

• a plurality of independently rotatable, coaxially aligned spools rotatable about a same rigid member that is independent from the spools, each one of the plurality of spools housing a constant force spring that is fixed to an inner circumferential wall of the spool at a first end, and fixed to the rigid member at a second end;
• a corresponding plurality of relatively inelastic, flexible biasing members, each coupled on a first end to an exterior contact point on an exterior circumferential surface of one of the spools and at least partially wound around the spool associated with the constant force spring;
• a corresponding plurality of connectors, each connector attached to a second end of one of the relatively inelastic, flexible biasing members, and each including a reversible couplers configured to quickly couple to and decouple from the object;
• and
• a guide mounted on a vertical support, the guide including one or more slides extending between the vertical support and the object, the guide providing a partial path for one or more of the biasing members extending through a length of the one or more slides to the object;
• wherein a desired load may be applied to the object by selectively coupling one or more of the reversible couplers to the object, such that when the object is coupled to the one or more of the reversible couplers, any repositioning of the object from a first position to a second position results in a negligible change in the desired load being operatively translated to the object through the one or more reversible couplers and associated one or more flexible biasing members from the associated one or more constant force springs;
• wherein each one of the plurality of spools is housed in a same casing rigidly affixed to the vertical support adjacent the one or more slides such that a user can selectively couple the one or more of the reversible couplers to the object to discretely adjust the desired load on the object, the casing formed as a closed body disposed about the plurality of spools;
• and
• wherein an outer surface of the casing defines a plurality of slots, each one of the slots configured to allow extension and retraction of a corresponding one of the biasing members through the slot.
