Abstract: A cable-operated exercise device includes an adjustable arm. The adjustable arm includes an adjustment mechanism that is operable by a single hand. To adjust the vertical angular position of the arm, the user pulls a pin out of a positioning hole on an adjustment plate. The arm is counterbalanced about a pivot connection so that the position of the arm does not change when the pin is pulled out of the positioning hole. The user then moves the arm into a second position and puts the pin back into a second positioning hole.

Abstract: A treadmill may include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, and a runaway mitigation mechanism in at least indirect mechanical communication with the motor. The runaway mitigation mechanism at least mitigates a motor runaway condition.

Abstract: A method for cooling a motor on a treadmill includes rotating a flywheel with a drive motor. A ring member coupled to the flywheel is be rotated with the flywheel. A pressure drop is generated in an annulus of the ring member between the drive motor and a lift motor. Intake air is drawn in a first direction across the lift motor toward the pressure drop.

Abstract: A treadmill may include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, and a runaway mitigation mechanism in at least indirect mechanical communication with the motor. The runaway mitigation mechanism at least mitigates a motor runaway condition.

Abstract: A treadmill may include a platform, at least one pulley attached to the platform, a sliding surface of the platform, a tread belt riding portion of the sliding surface, a tread belt surrounding the pulley and the sliding surface, the tread belt having at least one side edge, and a belt guide incorporated into the platform. The belt guide includes a textured portion of the sliding surface aligned with the side edge of the tread belt and spaced apart therefrom when the tread belt is positioned entirely within the tread belt riding portion. When the textured portion comes into contact the tread belt from the tread belt being misaligned out of the tread belt riding portion, the tread belt and the textured portion collectively produce a misalignment sound audible to a user when the tread belt moves against the sliding surface.

Abstract: A treadmill includes a deck, an incline mechanism attached to the deck, and a lift assist mechanism that offloads a portion of the lifting force from the incline mechanism when the incline mechanism changes an elevation of a portion of the deck.

Abstract: An exercise machine may include a deck, a lift motor connected to the deck, and a cooling mechanism that cools the lift motor when the cooling mechanism is activated.

Abstract: An exercise machine may include a deck, a motor housing incorporated into the deck, a lift motor located in the motor housing, and a cooling mechanism that cools the lift motor when the cooling mechanism is activated. An airflow pathway may be defined to direct air from the cooling mechanism to a location above the motor housing and on to a user of the exercise machine. The exercise machine may be configured such that upon beginning operation of the machine, substantially all of the airflow exhausts to the location above the motor housing. A mechanism may be provided to selectively alter a characteristic of the airflow after the exercise machine has begun operation.
