ABSTRACT:
A door counterweight assembly for positioning on a door shaft is disclosed. A pair of spaced disks are mounted on the door shaft and a tape drive member extends between the disks parallel to the door shaft. A continuous flexible tape has a portion surrounding the shaft. The flexible tape is positioned between the shaft and the drive member. The tape includes another portion which supports a counterweight. Rotation of the shaft folds the tape in a generally circular configuration to increase the counterweight torque applied to the shaft.
