Abstract
An exercise device includes two foot carriage assemblies. The foot carriage assemblies are operable to support a user's feet on a frame and to travel along a generally lateral path of motion. The foot carriages are operable to engage first and second torque tubes, which in turn participate in resisting the lateral movement of the foot carriages. A lateral striding motion on the exercise device may include a simulation of a motion associated with skating and/or skiing.
Claims16
An exercise device to simulate various types of lateral striding motions, comprising:
- a frame oriented along a longitudinal axis, the frame configured to be supported on a surface;
- a drive shaft rotatably mounted to the frame along the longitudinal axis;
- first and second torque tubes, each torque tube mounted on the drive shaft and configured to transfer torque to the drive shaft in at least one direction of rotation;
- first and second foot carriage assemblies operable to reciprocate along the frame in the longitudinal direction, the first and second foot carriage assemblies operable to rotate the respective torque tubes upon laterally traveling toward a lateral-most position along the frame;
- and
- resistance means for selectively resisting the rotation of the drive shaft.

An exercise device to simulate various types of lateral striding motions, comprising:
- a frame defining a longitudinal axis, the frame configured to be supported on a surface;
- first and second torque tubes, each torque tube rotatably mounted along the longitudinal axis of the frame;
- first and second foot carriage assemblies operable to move in the longitudinal direction on the frame, at least one of the foot carriage assemblies operable to engage the torque tubes and cause rotation therein upon laterally traveling toward a lateral-most position along the frame, promoting a rotation of the torque tubes;
- and
- first and second biasing systems associated with the first and second torque tubes, respectively, and operable to resist the rotation of the torque tubes and the lateral movement of the foot carriage assemblies.
