ABSTRACT:
Disclosed is a modular walkway for elevated access to building structures, and for protectively covering sidewalks adjacent to such structures, including a plurality of canopy modules that are connected end-to-end when erected, and nestedly stackable for compact storage. Each of the canopy modules has a wall structure and a roof walkway cantilevered thereto, a face structure being movably connected to an edge extremity of the walkway. In an erected configuration, each module is supported by adjustable feet at the bottom of the wall structure, and a pair of columns that support opposite ends of the face structure, the face structure extending vertically above and below the walkway and strengthening the walkway. The face structure is foldable substantially into the plane of the walkway for providing a convenient and compact nested configuration of the modules when stacked.
