Hinged bottom roller assembly and counterbalance mechanism for overhead door
An overhead door assembly configured to be coupled to a storage container, such as a truck trailer, including an overhead door including a plurality of door panels hingedly coupled to one another and a bottom roller assembly coupled to a bottom panel of the door. The bottom roller assembly includes a hinge and a roller coupled to a lower hinge plate of the hinge. The roller includes a shaft and a roller wheel coupled to one end of the shaft. Illustratively, the lower hinge plate and the roller thereon are configured to pivot about a pivot axis of the hinge relative to the bottom panel of the door between a first position generally adjacent the bottom panel of the door and a second position spaced-apart from the bottom panel of the door.
