MODULAR BASE LINK FOR A COUNTERBALANCING ARM

摘要

Disclosed is a modular base link for use in a counterbalancing arm. The base link includes two base plates and four connection points. Two stabilizing members are connected to and extend between the base plates. Two resilient members, one of which is hingeably connected to and in communication with the two connection points, the other resilient member is hingeably connected to and in communication with the other connection points. The connection points are eccentrically and orthogonally disposed relative to each other. The resilient members are sufficiently resilient to permit movement of the base plates relative to each other so as to counterbalance the arm when a load is applied to either base plate.
