ABSTRACT:
BACKGROUND OF THE INVENTION
Various forms of aerobic exercise are intended to develop different parts of the body. It would be desirable if the aerobic exercise could be supplemented by the user stepping up to and down from a horizontal platform. It would also be desirable if the height of the platform could be selectively adjusted to meet the individual needs of the user.
Various patents exist in the name of co-applicant William T. Wilkinson relating to adjustable steps. The prior art versions generally involve a fixed pair of supports wherein the platform or step itself is adjusted in height in accordance with the specific mounting of the step to the supports.
U.S. Pat. No. 5,158,512 relates to an adjustable step in which a platform is provided with a plurality of detachable support elements to provide height adjustability in accordance with the number of support elements used. There is no suggestion, however, of using the platform alone as the lowest height level.
SUMMARY OF THE INVENTION
An object of this invention is to provide an aerobic climbing step/bench device wherein the height adjustability is achieved by means of a detachably mounted leg assembly.
In accordance with this invention one height level could be achieved by providing an exercise step having a base and a plurality of legs. The uppermost portion of the base is substantially horizontal and planar to comprise a stepping platform. The base also includes an apron extending downwardly and terminating in a lowermost portion which is substantially horizontal and planar and parallel to the platform. Each leg has a lowermost portion which is also substantially horizontal and planar. Mounting means and complementary mounting means are provided on the base and legs or vice versa for the detachable engagement of the legs to the base. As a result, the platform has a first substantially horizontal height level when the base is placed directly on a support surface such as the floor. The platform has a second higher height level when a set of the legs is mounted to the base and the legs is placed directly on the support surface or floor.
Various means may be utilized for detachably mounting the leg assembly to the platform. Additionally, multiple sets of legs and multiple mounting means and complementary mounting means may be used to achieve additional possible height levels. Preferably at least one set of mounting means includes a cylindrical post and a recess shaped to receive the post.
