  • Patent number: 8974353
    Abstract: The present invention relates to a stair exercise device for simulating stair climbing, the device having a plurality of steps which are activated by the weight of a person walking up them. A stationary platform at the base of the stair exercise device sends a signal to a controller to bring the exercise device to a controlled stop when an operator steps onto the platform. The steps of the exercise device stop in a predetermined location when the exercise device comes to a controlled stop, ensuring proper step location to allow the operator to easily enter and exit the exercise device. Steps have a step platform of a different color than the risers between steps to aid in foot placement.

  • Patent number: 8182399
    Abstract: A foldable treadmill comprising a base bracket, a deck coupled to the base bracket for moving between a use position and a stored position, a support post extending upwardly and movably coupled to the deck, and a handle pivotally connected to the support post. A handle linkage can be coupled to the handle, and a lifting device can be coupled between the base bracket and the handle linkage for moving the handle when the deck is being moved. In one embodiment, the lifting device includes a support rod coupled to the support post and a deck rod coupled between the base bracket and the support rod. In this embodiment, the support rod has a first portion slidably coupled to the deck and another portion coupled to the handle linkage. The treadmill can further include a control panel movably coupled to the top portion of the support post. Preferably, a link bar is coupled between the control panel and the handle for moving the control panel when the deck is being moved.

  • Publication number: 20080020898
    Abstract: A training machine provides two independently operable resistance systems for providing resistance to the upper and lower body of a user and to enable training equivalent to circuit training in a small amount of time. A first resistance system provides training resistance to the upper body and comprises a first resistance member with handles coupled thereto. A second resistance system provides a second training resistance to the lower body, and comprises a seat support and a seat, the seat having a first position with a first potential energy and a second position having a second potential energy, the differential providing the second training resistance. Handles are each independently coupled to the first resistance member by a cable fed through a pulley to a cable reel assembly so as to enable the user to operate the handles separately from each other and in any direction.
