Abstract
An apparatus for setting up a ladder or a step on a staircase comprises: a platform on which the ladder or the step can be set up; and a frame to support the platform on the staircase. The frame comprises at least two legs each pivotable about a common pivot axis or about respective pivot axes, wherein the common pivot axis or the respective pivot axes lie in a plane of the platform or parallel to the plane of the platform.

An apparatus for setting up a ladder or a step on a staircase, comprising:
- a platform on which the ladder or the step can be set up, the platform comprising a plate having an upper surface, a lower surface, opposite longitudinal side edges extending between the upper surface and the lower surface, and a rim comprising hollow profiles connected to the plate, wherein the hollow profiles extend at least along the opposite longitudinal side edges and enclose the side edges;
- and
- a frame to support the platform on the staircase, the frame comprising at least two arms which are guided displaceably in the hollow profiles of the rim,
- wherein the hollow profiles of the rim are configured to fasten extractably the arms along the opposite longitudinal side edges of the plate, and
- wherein the arms are independently extractable from the hollow profiles of the rim to different lengths beyond an edge of the plate extending between the opposite longitudinal side edges in a plane of the plate corresponding to one of the upper and lower surfaces or in a plane parallel to said plane.
