OVERHEAD DOOR BACKUP SPRING SYSTEM
The present invention essentially comprises an overhead door backup spring system and method for providing an auxiliary spring counterweight to operate an overhead door shaft upon failure of a spring. The system has an activation unit, an engagement unit operably associated with the activation unit, and an auxiliary spring engagement unit operably associated with the engagement unit and an auxiliary spring. The engagement unit is engageable with the auxiliary spring to transfer torque from the auxiliary spring to the overhead door shaft. In an engaged position the engagement unit is engaged with the auxiliary spring engagement unit upon operation of the activation unit when the spring fails. In a non-engaged position the engagement unit is in non-engagement with the auxiliary spring engagement unit.
