  • Adjustable stride elliptical motion exercise machine with large stride variability and fast adjustment
    Patent number: 9636540
    Abstract: Elliptical exercise machines with a footskate on a reciprocating rail that provides for the ability to alter the horizontal stride of the user utilizing the machine, without significantly altering their vertical stride height on the machine. This is generally performed by altering the angle through which any point on the rail can, and does, move. Such adjustment may be performed by having the rail attached to a swing arm, where the arc of rotation of the swing arm relative to the frame is altered.

  • Open Handgrip for an Exercise Machine
    Publication number: 20160263426
    Abstract: A handgrip which has two terminating ends that does not connect with the other components to form a closed loop but instead form an open loop in the form of a “C”, inverted “C”, “U”, or inverted “U” depending on the side of the exercise machine the grip is to be used on and the manner of viewing it. This is commonly referred to as an open structure as this provides for a handgrip which does not fully circumscribe an area. It only partially circumscribes an area and creates a structure with two terminating ends on each handle.
