Abstract
A protective roof device for installation in an elevator shaft includes: a protective roof support that can be installed in the elevator shaft at different longitudinal positions; a protective roof supported by the support for catching falling objects and having at least two protective roof parts at least partly overlapping in an overlap region, the width of which can be modified by moving the roof parts relative to one another in an x-direction; each of the roof parts being foldable along a folding line and arranged such that the folding lines of different roof parts form a common folding line that is parallel to the x-direction; the width of the protective roof being variable in the x direction by modifying the width of the overlap region; and the depth of the protective roof being variable modified in a y direction by folding the protective roof along the common folding line.
