Adjustable structural support system for overhead garage door

A structural support system for an overhead door panel assembly, the structural support system comprising:

• an adjustment mechanism comprising (i) a mounting structure configured to mount the structural support system at a side of a door panel of the overhead door panel assembly, (ii) a threaded shaft extending from the mounting structure, (iii) an adjustable portion that is movable along the threaded shaft and (iv) a flexible strap;
• wherein the flexible strap comprises opposing end regions and a central region between the opposing end regions, and wherein, with the structural support system mounted at the side of the door panel of the overhead door panel assembly, (i) the opposing end regions of the flexible strap are attached at respective perimeter side regions of the door panel and (ii) the central region of the flexible strap extends along the side of the door panel between the perimeter side regions;
• wherein, with the structural support system mounted at the side of the door panel of the overhead door panel assembly, (i) the mounting structure is disposed at the side of the door panel and between the central region of the flexible strap and the side of the door panel, (ii) the threaded shaft extends from the mounting structure and through an aperture formed through the central region of the flexible strap and (iii) the adjustable portion engages the central region of the flexible strap near the aperture and is movable along the threaded shaft to adjust spacing between the central region of the flexible strap and the side of the door panel;
• wherein the adjustable portion comprises (i) a first threaded receiver disposed along the threaded shaft between the central region of the flexible strap and the mounting structure and (ii) a second threaded receiver disposed between the central region of the flexible strap and an end of the threaded shaft distal from the mounting structure;
• wherein, with the structural support system mounted at the side of the door panel of the overhead door panel assembly, and with the central region of the flexible strap spaced from the side of the door panel, the flexible strap applies a biasing force at the door panel in a direction parallel to a longitudinal axis of the threaded shaft;
• wherein, with the structural support system mounted at the side of the door panel of the overhead door panel assembly, and with the flexible strap forming a concave shape relative to the side of the door panel, the flexible strap engages the first threaded receiver and the biasing force is toward the side of the door panel;
• and
• wherein, with the structural support system mounted at the side of the door panel of the overhead door panel assembly, and with the flexible strap forming a convex shape relative to the side of the door panel, the flexible strap engages the second threaded receiver and the biasing force is away from the side of the door panel.
