Dual manual disengagement mechanism for an electric transit door operator

A dual manual disengagement mechanism for an electric transit door operator having a disengagement shaft extending from the operator comprising:

• a first pinion lever secured to the disengagement shaft having a plurality of gear teeth;
• a second pinion lever having a plurality of gear teeth intermeshed with the gear teeth of the first pinion lever such that when the first lever rotates with the disengagement shaft the second lever also rotates and vice versa;
• a first pull means connected to the first pinion lever via a clevis end having an elongate slot, said first pull means extending in a first direction;
• and
• a second pull means connected to the second pinion lever via a clevis end having an elongate slot, said second pull means extending in a second direction generally opposite the first direction, and
• wherein the length of the slots in the clevis ends is such that the pulling of one pull means to rotate the disengagement shaft to the disengagement position will not cause a tug on the other pull means.
