Abstract
An overhead door system featuring independent, unconnected panels is described. Each panel end is operatively carried within a pair of parallel tracks. The weight of the door decreases as the door is lifted and each panel completely disengages from its adjacent panel as it reaches the stacked position. This allows for a linear spring torque to door weight relationship requiring a very small motor compared to existing designs to provide the lifting torque necessary to operate the door.
