Overhead door backup spring system
The present invention essentially comprises an overhead door backup spring system for providing an auxiliary spring counterweight to operate an overhead door shaft upon failure of a spring. The system has an activation unit, a control assembly, an engagement assembly operably associated with the activation unit, and an auxiliary spring engagement assembly operably associated with the control and engagement assemblies. The control assembly has an engagement block engageable with a spring post of the auxiliary spring assembly. The engagement assembly has an engagement post engageable with the spring post to transfer torque from the auxiliary spring to the overhead door shaft. An engaged position has the engagement post not engaged with the spring posts while the engagement block is engaged with the spring post. A non-engaged position has the engagement post engaged with the spring post, and the engagement block not engaged with the spring post.
