Patent attributes
The present invention pertains to an exercising apparatus comprising a coupling mechanism and a synchronizing mechanism. The coupling mechanism is a rack assembly that includes two elongated bars extending longitudinally within the deck of the apparatus. The elongated bars receive a vertical arm of a platform when inserted through longitudinal slots of the deck. Each end of the elongated bar terminate with a wheel for rolling on a respective trough. The elongated bars further including vertical teeth disposed on the inner surface of each elongated bar for engaging the synchronizing mechanism. A pinion assembly includes a central wheel that rotates about a vertical axis. The external teeth of the central wheel are thereafter meshed with the vertical teeth of the elongated bars to provide synchronous movement as the elongated bars reciprocate.
