Abstract: A sill assembly that can include a sill and one or more threshold inserts. The threshold inserts can cover cavities within the sill. The sill assembly can optionally include a subsill, which can be a separate from or part of the sill. The subsill can include subsill cavities aligned over the sill cavities to form vertically-stacked pressure chambers. These vertically-stacked pressure chambers can include vertically-stacked pressure chambers positioned within the interior of the building, and vertically-stacked pressure chambers positioned within the exterior of the building. The sill assembly is so structured that different door types, such as swing doors, pivot doors, folding doors and/or sliding doors can be accommodated using the same sill and subsill by simply changing the threshold inserts. The sill assembly can have a minimal rise above the floor surface to meet regulatory requirements such as the Americans with Disabilities Act (ADA).

Abstract: A subsill positioned at least partially under a sill in a sill assembly. The sill assembly positioned under a door or window. Two or more pressure chambers extend lengthwise between the subsill and sill. Pressure chambers can extend one behind another. The subsill can include a backstop with some of the pressure chambers extending lengthwise between the backstop and the sill. Apertures in the pressure chambers are positioned to force water to flow by a circuitous path.

Abstract: 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.
