Patent number: 8062187Abstract: The present invention provides for a variable stride exercise device having a variable size close curved striding path during use. The exercise device described and depicted herein utilizes various configurations of linkage assemblies, cam members, and other components, connected with a frame to allow a user to dynamically vary his stride path during exercise. An exercise device conforming to aspects of the present invention provides a foot path that adapts to the change in stride length rather than forcing the user into a fixed size path. Some embodiments of the exercise device include a lockout device that selectively eliminates the variable stride features of the exercise device and allows the user to exercise in a stepping motion. Other aspects of the present invention relate to a releasable connection mechanism that can be used to selectively and/or automatically limit or eliminate the variable stride feature of an exercise device.Type: GrantFiled: June 15, 2010Date of Patent: November 22, 2011Assignee: Nautilus, Inc.Inventors: Andrew P. Lull, Keith M. Weier, Zachary D. Krapfl, Chester F. Kowalewski, Jonathan B. Watt

Publication number: 20100285928Abstract: The variable stride exercise device utilizes various configurations of linkage assemblies, cam members, and other components, connected with a frame to allow a user to dynamically vary the user's stride path during exercise. The exercise device allows for a foot engagement member travel path that adapts to the change in stride length rather than forcing the user into a fixed size path. A user's exertion level may have several components impacting the stride length provided by the machine, such as leg power, torso power, and (in versions of the exercise apparatus with arm supports or exercise components) arm power. The exercise device may include a lockout device that selectively eliminates the variable stride features of the exercise device and allows the user to exercise in a stepping motion.Type: ApplicationFiled: July 19, 2010Publication date: November 11, 2010Applicant: Nautilus, Inc.Inventors: Andrew P.
