Definitions

  • Dual treadle treadmills provide two moving surfaces that articulate relative to each other. These dual treadle treadmills provide both a treadmill-like motion and a stair climber-like motion. This combination of motions provides an exercise that simulates climbing a flight of stairs and provides similar health benefits to users.
  • Existing dual treadmills include several drawbacks, such as unnatural motions that result from existing mechanisms for operating dual treadle treadmills.
  • An embodiment of the invention provides a dual treadle treadmill.
  • the dual treadle treadmill includes a frame, a first treadle, a second treadle, a clutch axle, and a tensioning mechanism.
  • the first treadle and the second treadle are each pivotally coupled with the frame and each have a moving surface.
  • the clutch axle includes an axle, a first driver, and a second driver.
  • the axle is rotatably connected to the frame.
  • the first driver is coupled to the axle by a first clutch.
  • the first clutch transmits torque between the first driver and the axle in response to the first driver rotating in a first direction relative to the axle.
  • the first treadle is connected to the first driver through a first link such that the first driver is rotated in a first direction in response to the first treadle being pivoted in the first direction.
  • the tensioning mechanism maintains a tension on the first link.

  • the treadles 102 are synchronized such that when the first treadle 102A is at its highest position, the second treadle 102B is at its lowest position. Motion of the first treadle 102 A may be linked to motion of the second treadle 102B, such that in response to an end of the first treadle 102A moving in a substantially downward direction, an end of the second treadle 102B moves in a substantially upward direction.
  • Each of the treadles 102A, 102B include a moving surface on which a user may step.
  • the moving surface of a treadle in some embodiments, includes a belt that translates along a top surface of the treadle.

  • the two drive links may work in concert to manage the fall rate of the treadles 102.
  • the drive link 202 A engages a driver on the clutch axle 204. Motion of the drive link 202 A may cause the driver on the clutch axle 204 to rotate.
  • the driver is attached to the clutch axle 204 by a one-way clutch that causes the clutch axle 204 to rotate in one direction as the drive link 202A moves up and down. The driver and the clutch axle 204 are described in greater detail below.

  • the generator 208 receives rotation from the pulley system 206 and converts the rotation to electrical energy.

  • the generator 208 may be an alternator, a dynamo, a singly-fed generator, a doubly-fed generator, or another type of generator.
  • the generator 208 may be connected to a variable electrical load device.
  • the variable electrical load device applies a variable electrical load to the generator 208. Applying an electrical load to the generator 208 may have a braking effect on the generator 208 to increase the braking torque provided by the generator 208, thus reducing the fall rate of the treadles 102.
  • the variable electrical load device is described in greater detail below in relation to Figure 9.

Abstract

La présente invention se rapporte à une trépigneuse à deux pédales qui comprend un cadre (1304), une première pédale (1302A), une seconde pédale (1302B), un axe d'embrayage (1306) et un mécanisme de tension (1308). Les pédales sont chacune couplées au cadre (1304). L'axe d'embrayage (1306) comprend un axe (1806), un premier dispositif d'entraînement (1804A) et un dispositif d'entraînement (1804B). L'axe (1806) est raccordé en rotation au cadre (1304). Le premier dispositif d'entraînement (1804A) est couplé à l'axe par un premier embrayage. Le premier embrayage transmet un couple entre le premier dispositif d'entraînement (1804A) et l'axe (1806) en réponse à la rotation du premier dispositif d'entraînement (1804A) dans une première direction par rapport à l'axe (1806). La première pédale (1302A) est raccordée au premier dispositif d'entraînement (1804A) au moyen d'une première liaison (1802A) de telle sorte que le premier dispositif d'entraînement (1804A) tourne dans une première direction en réponse au pivotement de la première pédale (1302A) dans la première direction.
