Abstract

A block having a plurality of steps of different heights and useful as a stepladder for reaching different heights, depending on the size of the person. By laying the block selectively on any one of the three side and base surfaces, about nine different levels of height can be achieved. A pair of such blocks with a scaffoldboard inbetween supported at selective heights may be used for wall cleaning and the like.

Claims

1. A ladder block having a plurality of steps of sufficient size to stand thereon, including a pair of steps along one side to give two step levels and integral with a pair of steps of greater height on the other side thereof to give two additional higher step levels, making a total of four step levels surrounded by four flat, stepped sidewalls, a common rectangular base underlying all four of said step levels, additional levels being provided by tilting the block by 90* so that at least two of said sidewalls may be used selectively as the base surface resting on the floor so as to give a total of nine step levels.

2. A ladder block as recited in claim 1 having a hole extending along the vertical corner of greatest height, a work table supported by a post extending into said hole, which work table is positioned higher than the uppermost step of the block.
