Abstract:
An overhead garage door opening and closing system for a building structure having a track system comprising a pair of spaced apart tracks; a plurality of hinged door panels hingedly connected together to form the door; a plurality of track wheel assemblies disposed at said door panels, wherein each of said plurality of track wheel assembly comprises a shaft and a wheel rotatably mounted at said shaft and rotatable about an axis of rotation of said wheel, and wherein said door panels move along said tracks via rolling engagement of said wheels of said track wheel assemblies with said tracks as said door panels move between an opened position and a closed position; wherein said track wheel assemblies, when disposed at said door panels, are configured to allow for movement of the respective door panel relative to said wheels in a direction generally normal to said axes of rotation of said wheels and generally normal to a direction of travel of said wheels along said tracks; a door moving assembly that functions to move each of said door panels toward the building structure when the door is moved toward and to its closed position; and wherein, when said door moving assembly moves said door panels toward the building structure as the door closes, said door panels move relative to said wheels and toward the building structure and away from said axes of rotation and said wheels at said track.
