Abstract

A step for performing exercises is polygonal or circular to allow approaches from any direction equally. The step has a base member and a platform member, the platform member being selectively adjustable with respect to the base. The base member has lands equally spaced around the base member at different heights, and the platform member has shoulders equally spaced around the platform member to be received on the lands. By selecting the proper lands for the shoulders, the height of the platform can be changed. Also, the platform member may be used without the base member for a lower height step. Preferably there are five shoulders and five lands in each group of lands for stability of the platform.

Claims

1. An exercising step for use in aerobic exercise, said exercising step comprising a base member and a platform member, said platform member being selectively receivable on said base member and including an upper platform to receive the feet of a person exercising, and a skirt surrounding said upper platform, and means for varying the height of said platform member with respect to said base member for varying the height of said upper platform, said platform member having generally the same dimension in all transverse directions, said platform member defining a cavity therein within the confines of said skirt, the arrangement being such that said person steps on said upper platform in performing said aerobic exercise, said base member including a body, said body being selectively receivable within said cavity of said platform member, the arrangement being such that said means for varying the height of said platform member with respect to said base member selectively varies the extent to which said body is received within said cavity.

2. An exercising step as claimed in claim 1, said means for varying the height of said platform member including a plurality of groups of lands on said base member, said lands being spaced around said base member, and a plurality of shoulders on said platform member, said plurality of shoulders being spaced around said platform member and selectively receivable on one group of said plurality of groups of lands, each group of lands of said plurality of groups of lands being at a different height from a supporting surface for said base member.

3. An exercising step as claimed in claim 2, said base member being generally circular and including a bottom flange, each land of said plurality of groups of lands comprising a segment of said body, said body having an upper surface, each said group of lands being at a different distance from said upper surface of said body, each land within one group of lands being equiangularly spaced from other lands of said group, said platform member having a lower surface defining said plurality of shoulders, each shoulder of said plurality of shoulders being equiangularly spaced from the other shoulders of said plurality of shoulders, the arrangement being such that rotation of said platform member with respect to said base member aligns said plurality of shoulders with one group of said plurality of groups of lands for varying the height of said upper platform.

4. An exercising step as claimed in claim 3, wherein each said group of lands includes at least three lands within said group, and said plurality of shoulders includes at least three shoulders.

5. An exercising step as claimed in claim 4, wherein each said group of lands comprises five lands within said group, and said plurality of shoulders comprises five shoulders.

6. An exercising step as claimed in claim 4, and further including a plurality of feet fixed to said platform member, said plurality of feet depending from said lower surface of said platform member.
