Abstract
A dual manual disengagement mechanism for an electric transit door operator having a disengagement shaft extending from the operator comprises a first pinion lever (3) secured to the disengagement shaft, a second pinion lever (14) intermeshed with the first pinion gear, a first cable (17) connected to the first pinion-lever via a clevis end (15) having an elongate slot, a second cable (23) connected to the second pinion lever via a clevis end (16) having an elongate slot. The length of the slots in the clevis ends is such that the pulling of one cable to rotate the disengagement shaft will not cause a tug on the other cable.
