Providing Constant Counterbalance Throughout Predetermined Range of Motion

An apparatus includes a lever arm that couples to a pivot point on one end and a display on the other end. The lever arm rotates around the pivot point through a lever arm range of motion, and the weight of the display produces a display torque around the pivot point that varies as the lever arm rot...

Zusammenfassung:	An apparatus includes a lever arm that couples to a pivot point on one end and a display on the other end. The lever arm rotates around the pivot point through a lever arm range of motion, and the weight of the display produces a display torque around the pivot point that varies as the lever arm rotates through the lever arm range of motion. The apparatus also includes a spring that couples to the lever arm using a cable. The spring produces, through the lever arm, a spring torque around the pivot point that is equally opposite of the display torque throughout the lever arm range of motion.
