Abstract
An aerobic step device comprising a platform and a detachable leg assemblies for maintaining the platform at selected heights above a support surface. The platform has a skirt depending from the edges of a top, flat rectangular surface. Each leg assembly includes a pair of laterally extending arms, each of which have a protrusion which engages a selected one of at least a pair of slots that are provided on the inner surface of opposed sides of the skirt, the slots being longitudinally and vertically offset from each other. The height of the platform depends into which slot the protrusion is received into. Ribs and locking tabs depend from the underside of the top surface of the platform to engage respective channels and openings in the leg assemblies in order to stabilize the device in its operative positions.

10. An aerobic step device, comprising:
-
(a) A platform comprising a flat top surface, a pair of side walls depending from the opposed side edges of the top surface and a pair of end walls depending from the opposed end edges of the top surface, the bottom of the side walls and side edges being in a plane which is parallel to the top surface; (b) a leg assembly for maintaining the platform at selected heights above a support surface; and (c) means for detachably securing the leg assembly to the platform comprising a first slot and a second slot on each of the interior surfaces of the side walls and which are longitudinally and vertically offset from each other and a pair of protrusions on the leg assembly for respective engagement with the slots, whereby the platform is at a selected first or second height when the protrusions engage selected first slots or second slots.
