  • the lift assist device may comprise a pneumatic cylinder that extends between the base and the deck frame.
  • the pneumatic cylinder may be configured to store energy when the deck is lowered from the stored position to the operating position (e.g., energy may be stored in the pneumatic cylinder as compressed gas as the length of the pneumatic cylinder is retracted).
  • the stored energy in the pneumatic cylinder may then be utilized to assist in lifting the deck from the operating position (e.g., compressed gas in the pneumatic cylinder may expand, assisting in extending the length of the pneumatic cylinder).
  • the lift assist device may comprise one or more of a spring, a counterweight, and a pulley.
  • first and second motors, for the rear deck height adjustment mechanism and the front deck height adjustment mechanism, respectively, at the front portion of the deck may facilitate the movement of the deck between the operating position and the storage position.
  • the first and second motors may be positioned forward of the hinge point between the deck and the base of the treadmill. In this position, the weight of the first and second motors may provide a counter weight to the portion of the deck that extends rearward of the hinge point between the deck and the base of the treadmill. Accordingly, the amount of weight that a user would lift to move the deck from the operating position to the stowed position may be reduced.
  • the first and second motors may be positioned at or rearward of the hinge point between the deck and the base of the treadmill.
  • the first and second motors may be adjacent the hinge point, so that leverage provided by the length of the deck extending rearward of the hinge point may facilitate lifting of the deck and motors.
  • a treadmill may be configured to move the deck between the operating position and the storage position under the power of the first motor.
  • the first motor may be hingably attached to the base and positioned so that as the motor turns the elongate power transmission device beyond a certain point, the rear portion of the deck may be urged upward to the storage position.
  • a user may move the deck of the treadmill from the stored position to the operating position.
  • a user may then exercise on the treadmill while a variety of slopes are simulated by the treadmill.
  • a substantially flat surface may be simulated by the treadmill while a user runs on the treadmill, such as by lowering both the front deck height adjustment mechanism and the rear deck height adjustment mechanism to a fully lowered position, as shown in FIGS 1-3.
  • the front deck height adjustment mechanism may be raised to simulate running up a slope, as shown in FIG. 4B.
  • the first motor may be operated to raise the rear deck height adjustment mechanism to simulate running down a slope, as shown in FIG. 4A.
  • treadmills according to embodiments of the present disclosure may be utilized for training for running on varied terrain, including downhill slopes. Additionally, treadmills according to embodiments of the present disclosure may be utilized for low exertion exercises, such as walking down a decline, for users who are unable to exercise at high exertion levels or who are undergoing physical therapy for an injury.
