Patent number: 8585561Abstract: An exercise bike may include a magnetic braking system to resist rotation of a flywheel. The magnetic braking system may be magnets mounted on brackets selectively pivoted relative to the frame to increase or decrease the resistance opposing rotation of the flywheel. The brackets may be pivoted using a brake adjustment assembly joined to the brackets in such a manner that the magnetic forces resisting rotation of the flywheel increase or decrease in a proportional manner over at least a portion of the adjustment range of the brake adjustment assembly. The exercise bike may further include a console that displays information, such as power. The power may be estimated from a look-up table using the crank or flywheel speed of the exercise bike measured using a speed sensor and the tilt angle of the brackets relative to a reference point measured using a power sensor that includes an accelerometer.Type: GrantFiled: March 12, 2010Date of Patent: November 19, 2013Assignee: Nautilus, Inc.Inventors: Jonathan B. Watt, Kevin C. Andrews, Daniel S. Munson

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.

Publication number: 20100273612Abstract: The present invention is a seat height adjustment mechanism for exercise equipment having a seat. Examples of such exercise equipment include: stationary exercise bicycles; road or mountain type bicycles; resistance strength training supporting racks or platforms (e.g., preacher curl benches, military or shoulder press racks, etc.) for use with free weights; and resistance strength training machines that employ as resistance weight plates, deflectable members, elastic bands, springs, hydraulic cylinders, pneumatic cylinders, etc. The mechanism comprises a member, a telescopic member, and an engagement member. The member extends upwardly and includes a rack. The telescopic member includes a first end telescopically received in the member and a seat end. The engagement member is coupled to the telescopic member and adapted to engage the rack.Type: ApplicationFiled: May 3, 2010Publication date: October 28, 2010Applicant: Nautilus, Inc.Inventors: Jonathan B. Watt, Jonathan Harrach-Salazar, Mark N. Holtan

Patent number: 7749137Abstract: A variable stride device may include right and left foot engagement members operatively coupled to right and left cam-link assemblies, respectively. The cam-link assemblies may each be operatively coupled to a rotating member, such as a crank assembly, and to right and left swing arms, respectively. The cam-link assemblies may each include a cam member and first and second links. A user may engage the foot engagement members to move the foot engagement members in a substantially constant or variable elliptical, pseudo-elliptical or other stride path. The variable stride device may further include a resistance system for resisting movement of the foot engagement members.Type: GrantFiled: November 15, 2007Date of Patent: July 6, 2010Assignee: Nautilus, Inc.Inventors: Jonathan B.
