Abstract

A step for performing exercises is circular to allow approaches from any direction equally. The step has a base member and a platform member, the platform member being selectively movable with respect to the base. The base has a plurality of grooves, and the platform has a plurality of tongues to be received in the grooves. There are grooves of different depths so that, by selecting the proper grooves for the tongues, the height of the platform can be changed. An elastic may hold the base and platform together while allowing adjustment.

Claims

1. A step for use in exercising, said step including a platform member and a base member for supporting said platform member, said platform member including an upper circular platform onto which one can step for purposes of exercising, a plurality of tongues extending down from said upper platform, said tongues extending radially of said circular upper platform and being equiangularly spaced around said upper platform, and a skirt surrounding said upper platform, and said plurality of tongues said base member including a body defining a plurality of grooves therein, said grooves being arranged selectively to receive said plurality of tongues, said body of said base member being receivable within said skirt when said plurality of tongues is received within some of said plurality of grooves, said plurality of grooves comprising a first plurality of grooves of a first depth, and a second plurality of grooves of a second depth, said plurality of tongues being simultaneously receivable selectively in said first plurality of grooves and said second plurality of grooves for placing said upper circular platform selectively at a first height and a second height.

2. A step as claimed in claim 1, and including alignment means for maintaining said platform member in alignment with said base member.

3. A step as claimed in claim 2, said body defining a central opening therein, said platform member including an alignment member concentrically thereof, said alignment member being receivable within said central opening to constitute said alignment means.

4. A step as claimed in claim 3, and further including elastic means for attaching said platform member to said base member, said elastic means allowing limited separation of said platform member from said base member.

5. A step as claimed in claim 4, said base member defining a finger space in the bottom thereof for providing a handle for carrying said step.

6. A step as claimed in claim 5, wherein said plurality of grooves further includes a third plurality of grooves of a third depth for placing said upper circular platform at a third height.

7. A step as claimed in claim 1, wherein said plurality of tongues are of substantially equal lengths.
