Abstract

An exercise platform for use in a stair-step exercise routine and which is capable of supporting a person at a plurality of heights above a floor, includes a base section having first and second upwardly facing flat surfaces at first and second heights above a floor, and a riser section which is supported by the base section and includes third and fourth flat, oppositely facing surfaces. The riser section is connected to the base section with a hinge and is movable between first and second positions such that the third surface is upwardly disposed and located at a third height when the riser section is in the first position, and such that the fourth surface is upwardly disposed and located at a fourth height when the riser section is in the second position. Furthermore, a high friction coefficient material is disposed on the first, second, third and fourth surfaces to prevent slippage between the exercise platform and a foot of a person using the exercise platform.

Dependent claims

An exercise device for supporting a person at a plurality of heights, the platform comprising:

first supporting means for supporting the person at first and second heights, wherein the first supporting means includes first and second flat, parallel surfaces which support the person at the first and second heights, respectively;
second supporting means for supporting a person above the first supporting means, including third and fourth flat, parallel and oppositely facing surfaces, wherein the second supporting means is switchable between first and second positions such that the second supporting means lies immediately above the first flat surface so that the third flat surface is upwardly disposed at a third height when the second supporting means is in the first position and such that the second supporting means lies immediately above the second flat surface so that the fourth flat surface is upwardly disposed at a fourth height when the second supporting means is located in the second position;
and
connecting means for connecting the second supporting means to the first supporting means to enable the second supporting means to be switchable between the first and second positions;
wherein the entire weight of the second supporting means is supported by a combination of the first flat surface and the connecting means when the second supporting means is located in the first position and the entire weight of the second supporting means is supported by a combination of the second flat surface and the connecting means when the second supporting means is located in the second position.
