Patent number: 11266871Abstract: A stair exerciser apparatus for simulating stair climbing includes a frame, a lower shaft and an upper shaft mounted rotatably on the frame, a conveyor operatively engaged with the upper shaft and the lower shaft, a plurality of steps, a flywheel and a one-way clutch mechanism. The plurality of steps are joined to the conveyor for movement with the conveyor. The flywheel is operatively engaged with the conveyor. The one-way clutch mechanism is operatively engaged with the conveyor and the flywheel. The one-way clutch mechanism is configured to selectively couple the conveyor with the flywheel such that motion of the plurality of steps in a first step direction drives rotation of the flywheel when the one-way clutch mechanism is engaged, and the one-way clutch mechanism decouples the conveyor from the flywheel when the one-way clutch mechanism is disengaged.Type: GrantFiled: February 11, 2020Date of Patent: March 8, 2022Assignee: Johnson Helth Tech Co., Ltd.Inventors: Robert C Burck, Michael J Fidler, Alexander E Hanson, Noel R Johnson, Mark J Kannel

Patent number: 9993682Abstract: A stair exerciser apparatus includes a frame having a pair of inclined supports, a drive mechanism, a plurality of stairs and an electromagnetic resistance device. The stairs are coupled to the drive mechanism for traveling around the pair of inclined supports. The electromagnetic resistance device is coupled to the drive mechanism to control the running speed of the stairs. The electromagnetic resistance device has a flywheel, an electromagnet and a brake unit. The electromagnet is coupled to the brake unit for controlling rotation resistance of the flywheel. The brake unit has a brake block for stopping the flywheel to stop the stairs. The brake unit is pivotally rotatable between a non-braking position where the brake block is pulled away from the flywheel when the electromagnet is energized and a braking position where the brake block is pulled to stop the flywheel when the electromagnet is loss of power.Type: GrantFiled: April 22, 2016Date of Patent: June 12, 2018Assignee: Johnson Health Tech Co., Ltd.Inventors: Noel R Johnson, Alexander E Hanson

Publication number: 20170304674Abstract: A stair exerciser apparatus includes a frame having a pair of inclined supports, a drive mechanism, and a plurality of stairs coupled to the drive mechanism for traveling around the pair of inclined supports. The driving mechanism has an upper shaft, a lower shaft and at least one drive chain mounted around the upper shaft and the lower shaft. A clutch mechanism is coupled to the upper shaft or the lower shaft of the drive mechanism. A flywheel is operationally coupled to the clutch mechanism, where the clutch mechanism couples the motion of the stairs to the rotation of the flywheel when the stairs are driven in a downward direction, and where the clutch mechanism decouples the motion of the stairs from the rotation of the flywheel when the stairs cease to be driven in the downward direction.Type: ApplicationFiled: April 22, 2016Publication date: October 26, 2017Inventors: Noel R. Johnson, Alexander E. Hanson
