Abstract
There is disclosed herein a hinge assembly comprising a mandrel having a longitudinal axis. A first arm is rotationally fixed relative to the mandrel and extends from one end of the mandrel generally transverse to the longitudinal axis. A second arm is rotatably connected relative to the mandrel about the longitudinal axis and extends from the opposite end of the mandrel generally transverse to the longitudinal axis. A coil spring is sleeved over and snugly surrounds the mandrel. Relative rotation of the first arm and the second arm in an opposite direction tightens the spring around the mandrel. Tightening of the spring generates resistance to relative rotation of the first arm and the second arm.
