Abstract
Abstract Apparatus and method of providing for a secure, rigidly positioned exercise platform to be utilized in conjunction with a fixed standup or sitdown cycling machine or any ordinary moveable cycling device. The device utilizes two oppositely positioned exercise platforms fixedly attached to platform shafts. These platform shafts are supported by carrier housings that are attached to a main shaft by means of a spacing and support bar. Stationary gears are attached to the ends of each platform shaft and are oppositely attached to the ends of the main shaft carrier housing. A free spinning connection means, in the form of a belt or a gear, is employed to connect the platform shaft gears and main shaft carrier housing gear. In operation, as a result of this configuration, the exercise platforms are held in a fixed position throughout the exercise cycle. The free spinning connecting means will "walk" around the stationary gears allowing for movement of the platforms while at the same time holding the platforms in their fixed positions. The device is specifically designed to be used by anyone in a desirable, safe, indoor, exercising environment and will also alleviate the problem of free moving pedals wiht pose a danger to the infirm or aged persons desiring exercise on a typical exercising machine. The angle of the platforms is easily adjustable should a different angle be desired. The device is rugged, easy to inspect, maintain and disassemble and is relatively inexpensive to produce.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
273 words
A fixed exercise cycling platform apparatus for supporting an exerciser comprising: a. a pair of support platforms upon which an exerciser's feet may be placed; b. resilient cushioning means attached to said support platforms for cushioning said exerciser's feet; c. platform shafts with one end of said platform shafts fixedly attached to the base of said support platforms so that said support platforms may be positioned at any desired angle and held there; d. a pair of stationary platform gear means attached to said platform shafts at the end of said platform shafts opposite from said support platforms; e. a pair of spacing and support bars securably attached at one end to platform shaft carrier housings, which surround said platform shafts between said support platforms and said stationary platform gear means and which include bushings so that said platform shaft rotates freely within said shaft carrier housings; f. a main shaft fixedly attached to the ends of each said spacing and support bars opposite from said platform shaft carrier housings; g. two oppositely positioned stationary main shaft carrier housing gear means aligned with said stationary platform gear means, fixedly attached to a main shaft carrier housing, which encloses said main shaft and includes bushings which enable said main shaft to rotate freely; and h. a pair of oppositely positioned free spinning connecting means engagably attached to both said stationary platform gear means and said stationary main shaft carrier housing gear means so that, when said exerciser pedals, said free spinning connecting means rotates about both said stationary gear means thereby allowing said support platforms to rotate while being held in a fixed position.
