Treadmill with foot fall monitor and cadence display
View Patent ↗In general, the present invention discloses treadmills that include a monitor that detects foot falls of a person exercising on the treadmill. Various mechanisms are described that can be incorporated on a treadmill to detect foot falls. For example, load cells, vibration monitors, motor load variance monitors, and sound monitors can be used to detect foot falls. A processing unit on the treadmill can receive data from the foot fall monitor to calculate a cadence, or a number of foot falls per unit time. Information relating to cadence can be displayed to the person exercising. In addition to a foot fall monitor, the present invention also discloses a monitor that detects foot lifts of a person exercising on a treadmill. A processing unit can receive data from the foot fall and foot lift monitors to determine and display stride length.
1. A treadmill comprising:
a frame;
a belt operatively associated with the frame, the belt having an upwardly exposed exercise section;
a motor operatively associated with the frame, the motor being configured to rotate the belt;
a foot fall monitor operatively associated with the frame, wherein the foot fall monitor is configured to identify the foot falls of a user performing an exercise on the belt;
a processing unit that is communicatively connected to the foot fall monitor, wherein the processing unit is configured to calculate an actual cadence of the user from data received from the foot fall monitor;
wherein the foot fall monitor is configured to detect a horizontal position of the user relative to the frame; and
wherein the treadmill is configured to regulate a speed of the belt based on the detected horizontal position of the user relative to the frame.
2. The treadmill of claim 1 , further comprising a console that includes an input mechanism to input information regarding a target cadence; and
at least one display disposed in the console, wherein the at least one display is communicatively connected to the processing unit, and wherein the at least one display is configured to display data reflecting the actual cadence.
3. The treadmill of claim 2 , wherein the at least one display is configured to display data reflecting the target cadence.
4. The treadmill of claim 3 , wherein the data reflecting the target cadence is a display of the target cadence.
5. The treadmill of claim 2 , wherein the console further includes a light configured to illuminate to signal that either the actual cadence is at or within an acceptable margin of the target cadence or that the actual cadence is outside of an acceptable margin of the target cadence.
6. The treadmill of claim 2 , wherein the console further includes a light configured to illuminate to signal that either the actual cadence is within five percent of the target cadence or that the actual cadence is not within five percent of the target cadence.
7. The treadmill of claim 2 , wherein the console further includes a light configured to flash at the rate of the target cadence.
8. The treadmill of claim 2 , wherein the console further includes a speaker configured to emit a sound at the rate of the target cadence.
9. A treadmill comprising:
a frame;
a belt operatively associated with the frame, the belt having an upwardly exposed exercise section;
a motor operatively associated with the frame, the motor being configured to rotate the belt;
a foot fall monitor operatively associated with the frame, wherein the foot fall monitor is configured to identify the foot falls of a user performing an exercise on the belt;
a console that is communicatively connected to the foot fall monitor, the console including a processing unit, a display, an input mechanism, and an indicator;
wherein the processing unit is configured to calculate actual cadence of the user from data received from the foot fall monitor;
wherein the display shows data reflecting the user's actual cadence;
wherein the input mechanism may be used to input information regarding a target cadence;
wherein the indicator is configured to provide a signal that relates to the target cadence; and
wherein the foot fall monitor is configured to detect a horizontal position of the user relative to the frame; and
wherein the treadmill is configured to regulate a speed of the belt based on the detected horizontal position of the user relative to the frame.
10. The treadmill of claim 9 , wherein the indicator is a display that is configured to show data reflecting the target cadence.
11. The treadmill of claim 9 , wherein the indicator is a light that is configured to flash at the rate of the target cadence.
12. The treadmill of claim 9 , wherein the indicator is a speaker configured to emit a sound at the rate of the target cadence.
13. A treadmill comprising:
a frame;
a deck connected to the frame;
a belt operatively associated with the frame and having an upwardly exposed exercise section that is supported by the deck;
a motor operatively associated with the frame, the motor being configured to rotate the belt;
a foot fall monitor operatively associated with the deck, wherein the foot fall monitor is configured to detect foot falls of a person exercising on the belt;
a foot lift monitor operatively associated with the deck, wherein the foot lift monitor is configured to detect foot lifts of a person exercising;
a console that is communicatively connected to the foot fall monitor and the foot lift monitor, the console including a processing unit and at least one display;
wherein the processing unit is configured to calculate a user's stride length from data received from the foot fall and foot lift monitors;
wherein the display is configured to show data reflecting the user's stride length; and
wherein the foot fall monitor is configured to detect a horizontal position of the user relative to the frame; and
wherein the treadmill is configured to regulate a speed of the belt based on the detected horizontal position of the user relative to the frame.
