Patent attributes
A folding panel system that allows foldable panels, such as folding glass doors, to fold and move around segmented tracks. The system includes a trolley assembly. The trolley assembly can include a pair of dual roller assemblies spaced rigidly apart by a rigid guide member and supported by an overhead guide track. The rigid guide member is positioned outside of the guide track and moves lengthwise along the overhead guide track except between overhead linear track segments. A hinge extension is secured to and extends rigidly away from the rigid guide member vertically away from the guide track. This configuration holds the hinge extension at a constant angle with respect to the guide track. The hinge extension pivotably joins hinge leaves from adjacent panels hingedly joining the two panels.
