Abstract
A counterbalance hinge mechanism for a cabinet lid includes a stationary cabinet affixed hinge rod serving to rotatably support a pair of axially stationary lid mounting cam members and to slidably support a pair of non-rotatable cam followers. An adjustable spring assembly serves to bias the cam followers into engagement with the cam members, whereby to counterbalance gravity induced torque effects of the lid throughout a substantial portion of lid opening movement.
