Abstract
An improved bi-fold shutter that includes a more efficient coupling mechanism at a hinge point suited to facilitate opening and closing the bi-fold shutter with greater ease. In one embodiment, the shutter may be designed for a window such that the shutter, when closed, is relatively close to the face of the associated window, and when open, forms an awning or overhang. The shutter includes an improved coupling mechanism at a hinge point between a first shutter portion and a second shutter portion. The improved hinge point shifts a direction of force needed to maneuver the shutter when moving the shutter from one position to another. The shift in opening and closing force directions improves the efficiency by which the shutter can be operated. In some embodiments, the shutter may be hand-operated. In other embodiments, the shutter may be powered.
