Treadmill control system
A microprocessor based exercise treadmill control system is disclosed which includes various features to enhance user operation. These features include programs operative to: permit a set of user controls to cause the treadmill to initially operate at predetermined speeds; permit the user to design custom workouts; permit the user to switch between workout programs while the treadmill is in operation; and perform an automatic cooldown program where the duration of the cooldown is a function of the duration of the workout or the user's heart rate. The features also include a stop program responsive to a detector for automatically stopping the treadmill when a user is no longer on the treadmill and a frame tag module attached to the treadmill frame having a non-volatile memory for storing treadmill configuration, and operational and maintenance data. Another included feature is the ability to display the amount of time a user spends in a heart rate zone.
1. An exercise treadmill comprising:
a frame;
a pair of pulleys rotatably mounted on said frame in a spaced parallel relation one to another;
a belt extending in contact with surfaces of said pulleys;
a motor for rotating at least one of said pulleys;
a control system operatively connected to said motor;
a control panel secured to said frame and operatively connected to said control system wherein said control panel includes at least one display and a first set of speed controls for permitting a user to variably control the speed of said belt wherein said speeds are not preset; and
a second set of speed controls operatively connected to said control system wherein said second set of speed controls includes a plurality of speed control buttons for permitting the user to cause said belt to move at a predetermined preset speed corresponding to each of said speed control buttons wherein each of said preset speeds is different and wherein each of said speed control buttons is marked with an indication of said preset speed for that speed control button.
2. The exercise treadmill of claim 1 wherein said control system additionally permits the user to change at least one of said preset belt speeds.
3. The exercise treadmill of claim 1 wherein said control system additionally permits the user to alter at least one of said preset belt speeds to a second preset speed in response to speed control input from said first set of speed controls.
4. The exercise treadmill of claim 1 wherein each of said preset speeds is preset in said control system.
5. An exercise treadmill as claimed in claim 1 wherein that said second set of speed controls includes three of said speed control buttons each of said speed control buttons having a corresponding one of said corresponding preset speeds wherein said first preset speed is within approximately one third of the treadmill's maximum belt speed, said second preset speed is within approximately the middle third of the treadmill's maximum belt speed and said third preset speed is approximately within the upper third of the treadmill's maximum belt speed.
6. The exercise treadmill of claim 1 wherein said second set of speed controls includes three of said speed control buttons and wherein said marking of said first speed control button indicates that its corresponding preset speed is a walking speed, said marking of said second speed control button indicates that its corresponding preset speed is a jogging speed and said marking of said third speed control button indicates its corresponding preset speed is a running speed.
7. An exercise treadmill as claimed in claim 1 wherein said control system includes a process that permits a user to change a selected one of said preset speeds by pressing the speed control button associated with said selected preset speed in combination with utilizing said first set of speed controls.
8. The exercise treadmill of claim 7 wherein said display displays said preset speeds in response to said first set of speed controls.
9. An exercise treadmill comprising:
a frame;
a pair of pulleys rotatably mounted on said frame in a spaced parallel relation one to another;
a belt extending in contact with surfaces of said pulleys;
a motor for rotating at least one of said pulleys;
a control system operatively connected to said motor;
a control panel secured to said frame and operatively connected to said control system wherein said control panel includes at least one display and a first set of speed controls for permitting a user to variably control the speed of said belt wherein said speeds are not preset;
a second set of speed controls operatively connected to said control system wherein said second set of speed controls includes a plurality of speed control buttons for permitting the user to cause said belt to move at a predetermined preset speed corresponding to each of said speed control buttons wherein an initial one of each of said preset speeds is different and set at the time of manufacture of the treadmill and wherein each of said speed control buttons is marked with an indication of said preset speed for that speed control button; and
wherein said control system includes a process that permits a user to change a selected one of said preset speeds by pressing a speed control button associated with said selected preset speed in combination with utilizing said first set of speed controls; and wherein said control system terminates said process for changing said preset speeds if said first set of speed controls are not used within a predetermined period of time.
