Aquatic step exercise apparatus
| Details |
Inventors: Hand, Peter H.; Saunders, William J.; Goldstein, Eric; Watson, James B.; Lockwood, J. Charles; Alsup, J. Douglas;
Assignee: The Aqua Step Corporation (Atlanta, GA)
Primary Examiner: Wilson; John J.

Attorney, Agent or Firm: Jones & Askew
Step exercise apparatus primarily intended for use in an aquatic environment such as a pool or the like. The apparatus includes a step platform maintained in elevated relation above a foundation surface by a pair of support members. The apparatus has a specific gravity greater than one so as to sink within a body of water, and slots extend through the platform to prevent entrapment of air bubbles when the platform is placed in a pool. Handles in the sides and ends of the apparatus assist the user in manipulating the apparatus while exercising in the water. Removable extension feet selectively increase the step distance between the platform and the pool bottom or other foundation surface on which the apparatus rests. |

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Turning first to FIG.
1, there is shown generally at 10 a step exercise apparatus having a platform 11 of generally rectangular configuration.
The two ends of the platform 11 join the corresponding support members 12 depending downwardly from the upper surface 19 of the platform.
The bottom 13 of each support member 12 is intended to support the exercise apparatus 10 on a level foundation surface such as a floor or the bottom of a swimming pool, and each corner of both bottoms preferably is equipped with one or more skid-resistant elements such as the pads 14 (FIG.
6) of an elastomeric or other material providing relatively good adhesion on wet or slippery foundation surfaces.
The sides 15 extend downwardly from the upper surface 19 of the platform 11 and form a skirt extending below the underside of the platform, as best seen in FIGS.
3 and 4.
The apparatus 10 including the platform 11 and support members 12, as described thus far, preferably is a unitary article formed by injection molding of suitable plastic material such as mineral-filled polypropylene or the like.
The preferred embodiment has a specific gravity somewhat greater than 1.
0 so as to sink when immersed in water, for reasons that become more clear below, and mineral-filled polypropylene has a specific gravity of approximately 1.
2.
The preferred range of specific gravities for the present exercise apparatus is 1.
15 to 1.
4.
However, the overall weight of the apparatus 10 in air should not be so great that the average user has difficulty in moving or carrying it.
The upper surface 19 of the platform 11 is generally level.
This upper surface is textured by one or more rows of lands or ridges 20 raised a short distance above the upper surface 19, to provide a firm footing for persons stepping onto and off the platform.
Each land 20 has a generally smooth upper surface parallel with the upper surface 19 of the platform and, as best seen in FIG.
5, the lands are elongated and extend diagonally partway across the width of the platform 11
