EXERCISE MACHINES AND METHODS FOR CONTROLLING EXERCISE MACHINES
An exercise machine configured for a user to perform an exercise motion. A first frame is configured to be positioned on a floor. A second frame is supported by the first frame, the second frame being manually moveable by the user relative to the first frame into a desired position for the user to perform the exercise motion. A sensor detects an actual position of the second frame relative to the first frame. A display device is configured to display the actual position detected by the sensor to assist the user in moving the second frame into the desired position.
1 . An exercise machine configured for a user to perform an exercise motion, the exercise machine comprising:
a first frame configured to be positioned on a floor;
a second frame supported by the first frame, the second frame being manually moveable by the user relative to the first frame into a desired position for the user to perform the exercise motion;
a sensor that detects an actual position of the second frame relative to the first frame; and
a display device that displays the actual position detected by the sensor to assist the user in moving the second frame into the desired position.
2 . The exercise machine according to claim 1 , wherein the second frame supports a seat upon which the user sits to perform the exercise motion such that the seat is moveable relative to the first frame.
3 . The exercise machine according to claim 1 , wherein the second frame slides relative to the first frame.
4 . The exercise machine according to claim 1 , wherein the sensor comprises a circuit board and a magnet that is moveable relative to the circuit board, wherein the circuit board detects a position of the magnet relative thereto, wherein moving the second frame relative to the first frame changes the position of the magnet relative to the circuit board, and wherein the position of the second frame relative to the first frame is detected based on the position of the magnet relative to the circuit board.
5 . The exercise machine according to claim 4 , wherein the circuit board is stationary relative to the first frame, and wherein the magnet moves with the second frame.
6 . The exercise machine according to claim 4 , further comprising a casing that at least partially covers one of the first frame and the second frame, wherein the casing has an outer surface with a channel extending inwardly therefrom, and wherein the circuit board is positioned in the channel to be at least partially protected below the outer surface of the casing.
7 . The exercise machine according to claim 6 , further comprising a cover that encloses the circuit board within the channel to protect the circuit board therein.
8 . The exercise machine according to claim 7 , wherein the cover comprises markings for visually indicating the actual position of the second frame relative to the first frame separately from the sensor.
9 . The exercise machine according to claim 1 , further comprising a control system having a memory system for storing the actual position of the second frame detected by the sensor as a stored position, wherein the display device is configured to display the stored position to assist the user in moving the second frame into the desired position.
10 . The exercise machine according to claim 9 , further comprising a second sensor configured to detect a speed at which the exercise motion is performed, wherein the control system is configured to automatically store the actual position of the second frame as the stored position only when the speed of the exercise motion exceeds a minimum threshold.
11 . The exercise machine according to claim 9 , wherein the display device is configured to display an indication when the actual position detected by the sensor is different than the stored position.
12 . The exercise machine according to claim 9 , wherein the display device is configured to display the stored position and the actual position detected by the sensor at the same time to assist the user in moving the second frame into the stored position as the desired position.
13 . The exercise machine according to claim 1 , wherein the sensor is a first sensor, further comprising a third frame supported by the first frame, wherein the third frame is manually moveable by the user relative to the first frame into a desired position for the user to perform the exercise motion, and wherein the third frame is moveable independently from the second frame, further comprising a second sensor that detects an actual position of the third frame relative to the first frame, wherein the display device displays the actual position of the third frame detected by the second sensor to assist the user in moving the third frame into the desired position thereof.
14 . The exercise machine according to claim 13 , wherein the second frame supports handlebars configured to be gripped by the user and the third frame supports a seat configured for the user to sit thereon to perform the exercise motion.
15 . The exercise machine according to claim 1 , wherein the exercise motion is performed by the user pedaling.
16 . A method for controlling an exercise machine, the exercise machine comprising a first frame configured to be positioned on a floor and a second frame supported by the first frame and manually moveable by a user relative to the first frame into a desired position for the user to perform an exercise motion, the method comprising detecting with a sensor an actual position of the second frame relative to the first frame and displaying with a display device the actual position detected by the sensor to assist the user in moving the second frame into the desired position.
17 . The method according to claim 16 , further comprising retrieving a stored position of the second frame relative to the first frame and displaying the stored position on the display device to assist the user in moving the second frame to the stored position as the desired position.
18 . The method according to claim 16 , further comprising retrieving a stored position of the second frame relative to the first frame, comparing the actual position detected by the sensor to the stored position, and indicating when the stored position and the actual position vary by at least a threshold difference.
19 . The method according to claim 16 , further comprising detecting a speed at which the exercise motion is performed, comparing the speed to a minimum threshold, and automatically storing the actual position of the second frame as a stored position when the speed of the exercise motion exceeds the minimum threshold.
20 . The method according to claim 16 , further comprising receiving height information for the user, determining a recommended position for the second frame relative to the first frame based on the height information, comparing the actual position detected by the sensor to the recommended position, and indicating when the recommended position and the actual position vary by at least a threshold difference.
