Patent ID: 8141680

Claim:
A stepping system comprising: a upper step platform having an upper step tread surface extending from an upper front edge to an upper rear edge and bounded by upper first and second lateral edges coupled at the upper front edge to an upper riser and to an upper rear side wall at the upper rear edge parallel to and spaced apart from the upper riser, and having first and second upper lateral side walls connected to and extending from the first and second upper lateral edges and in opposed spaced apart relation, together to define an upper step platform cavity having an upper step height selected to be no greater than six inches; a lower step platform having a lower step tread surface extending from a lower front edge to a lower rear edge and bounded by lower first and second lateral edges coupled at the lower front edge to a lower riser and to a lower rear side wall at the lower rear edge parallel to and spaced apart from the lower front riser at a lower step depth greater than twelve inches, and having first and second lower lateral side walls connected to and extending from the first and second lower lateral edges and in opposed spaced apart relationship at a lower step width greater than twelve inches, together to define a periphery sized to be receivable into the upper step platform cavity in a first position, wherein a lower step height is about half the upper step height; and a connection mechanism coupled to the upper step platform and configured to engage the lower step platform, the connection mechanism arranged such that the lower step platform is manually movable relative to the first step platform from the first position to a second position wherein the lower step platform extends from the upper riser to, in cooperation with the upper step platform to form a graduated platform, wherein the connection mechanism includes a pin having a rotational axis about which the second lower step platform rotates out of the first position into the second position.
