Abstract
An exercise machine including a weight measurement system which provides a signal representative of a user's weight. An embodiment of the weight measurement system includes at least one load cell outputting a signal used by a microprocessor to determine an accurate value of the users weight. An embodiment of the weight measurement system includes a plurality of load cells using a Wheatstone bridge configuration to output a signal representative of a user's weight regardless of whether the weight is evenly distributed across each load cell. A calibration process calibrates the load cells for each exercise machine.
Claims26
A treadmill capable of acquiring a representation of a current weight of a user through a plurality of load cells, the treadmill comprising:
- an electronic display including a processing device capable of governing an exercise of a user through one or more configuration parameters;
- a display support assembly including one or more handrails;
- an endless belt;
- a driving assembly including at least one motor capable of supplying movement to the endless belt to cause the user positioned on the endless belt to perform the exercise;
- and
- a frame including:
- a plurality of rollers defining a path for the endless belt, and
- a plurality of rail portions, each rail portion extending outwardly with respect to each side of the endless belt and housing at least one of a plurality of load cells, the plurality of load cells capable of outputting a representation of a current weight of the user based on the user's weight being applied to the plurality of load cells.
A treadmill comprising an electronic display, a handrail assembly, a frame, a weight measurement system and an endless belt disposed within the frame and around a plurality of rollers on each side of a deck, the endless belt being driven by a motor assembly to exercise a user positioned on the endless belt wherein the weight measurement system is capable of weighing the user without the user dismounting the treadmill and is capable of outputting a signal representative of a current weight of the user to a processor of the electronic display, wherein the processor is capable of using the representation of the current weight of the use in determining a physiological parameter indicative of an amount of exercise performed or being performed by the user.
A treadmill comprising an electronic display, a handrail assembly, a frame, a weight measurement system and an endless belt disposed within the frame and around a plurality of rollers on each side of a deck, the endless belt being driven by a motor assembly to exercise a user positioned on the endless belt, wherein the weight measurement system is capable of weighing the user without the user dismounting the treadmill and is capable of outputting a signal representative of a current weight of the user to a processor of the electronic display, wherein the weight measurement system comprises a plurality of load cells, each load cell mechanically connected to a footpad disposed on the frame near a periphery of the endless belt such that a user straddles the endless belt to step on each of the footpads.
