Protective roof with an adjustable width and depth for installing in an elevator shaft

A protective roof device for installation in an elevator shaft of an elevator system, the protective roof device comprising:

• a protective roof support configured to be installed in the elevator shaft in different positions in a longitudinal direction of the elevator shaft in an installed configuration, the protective roof support being removably attached to a rail system positioned in the elevator shaft in the longitudinal direction thereof;
• a protective roof supported by the protective roof support and configured to catch objects falling down the elevator shaft from above in the installed configuration;
• wherein the protective roof includes a first protective roof part and a second protective roof part, the first and second protective roof parts overlapping at least partially in an overlap region, and wherein the first and second protective roof parts are moveable relative to one another in a displacement direction to change a width of the overlap region;
• wherein the first and second protective roof parts are each foldable along an associated fold line and are arranged such that the fold lines form a common fold line that is parallel to the displacement direction;
• wherein a width of the protective roof is adjustable in the displacement direction by changing the width of the overlap region to adapt the width of the protective roof to a width of the elevator shaft;
• and
• wherein a depth of the protective roof is adjustable and adaptable to a depth of the elevator shaft in a direction orthogonal to the displacement direction by folding the protective roof along the common fold line.
