Step aerobic exercise device
First Claim
1. Exercise apparatus adapted to be mounted on a floor, comprising a platform, extensible members extendible from said platform, and adjusting means to control the extension of said extensible members from said platform, said members being extensible in opposite directions from said platform and having substantially coplanar supporting surfaces adapted for respectively receiving the feet of an exercising person, said platform having a supporting surface located at a selected fixed distance above the floor twice the height of said coplanar supporting surfaces, said members being at least partly accommodated within said platform, said means including an element interposed between said members to adjust the extension of said members in increments to different selectable extents, said coplanar supporting surfaces of said members, and said supporting surface of said platform forming steps.

Abstract
An exercise device is provided in the form of a central platform having two extensible wings which together with the supporting surface of floor on which the exercise device is supported forms along with the central platform a series of steps. The wings are spring loaded and controllable by a calibrated turnkey which enables the wings to be extended a determinable amount which correlates to the height of the individual using the device for purposes of exercise. To use the device, the exercising individual stands on the central platform and moves his feet from step to step, first down and then up, with the option of alternating between the user'"'"'s two feet.
