Publication number: 20240075374Abstract: A method for controlling a fitness machine having a light. The method includes receiving a preset time for a user to perform an exercise using the fitness machine, receiving a request to start the exercise, and controlling the light in a first operating mode. The method further includes counting an elapsed time since the exercise was started, determining a remaining time as a difference between the elapsed time and the preset time, and comparing the remaining time to a threshold time. The method further includes changing the light to a second operating mode different than the first operating mode when the remaining time is less than the threshold time to thereby indicate that the exercise will be ending.Type: ApplicationFiled: August 29, 2023Publication date: March 7, 2024Applicant: Life Fitness, LLCInventors: Matt Brennand, Tracy Barrett, Kyle Spoo, Ray Reitz

Patent number: 11865400Abstract: An exercise machine has a flywheel, a rotary input member, and a clutch mechanism that is positionable in a freewheel position in which rotation of the rotary input member causes rotation of the flywheel and wherein thereafter ceasing rotation of the rotary input member permits continued rotation of the flywheel. The clutch mechanism is alternately positionable in a direct drive position in which rotation of the rotary input member causes rotation of the flywheel and wherein thereafter ceasing rotation of the rotary input member prevents continued rotation of the flywheel. Advantageously, movement of the clutch mechanism from the freewheel position to the direct drive position is prevented when rotation of the rotary input member is out of synchronization with rotation of the flywheel.Type: GrantFiled: April 28, 2021Date of Patent: January 9, 2024Assignee: Life Fitness, LLCInventors: Andrew Muhic, Joseph J.

Patent number: 11745048Abstract: A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.Type: GrantFiled: February 6, 2023Date of Patent: September 5, 2023Assignee: Life Fitness, LLCInventors: Christian Shea Anderson, John R.

Publication number: 20230013687Abstract: A fitness machine operable by a user. The fitness machine has a base and a mobile portion that moves relative to the base during operation. A resilient body resists movement of the mobile portion towards the base in a height direction. The resilient body has a length defined in a length direction that is perpendicular to the height direction. The length of the resilient body increases when the mobile portion moves towards the base. An end stop is operable to prevent the length of the resilient body from increasing beyond a set maximum. The end stop is moveable to adjust the set maximum for the length of the resilient body, where a resistance provided by the resilient body to resist movement of the mobile portion towards the base is unaffected by moving the end stop when the length of the resilient member is less than the set maximum.Type: ApplicationFiled: September 16, 2022Publication date: January 19, 2023Applicant: Life Fitness, LLCInventors: Zhi Lu, Peter Kanakaris
