Abstract

A treadmill includes an exercise deck, and a tread belt on the exercise deck having multiple slats. At least one slat of the multiple slats has a first rod end and a second rod end protruding from the slat. A first track is defined in a first side of the exercise deck and a second track is defined in a second side of the exercise deck. The first track receives and guides the first rod end, and the second track receives and guides the second rod end.

First claim

What is claimed is:

1. A treadmill, comprising:
an exercise deck;
a tread belt on the exercise deck having multiple slats;
at least one slat of the multiple slats comprising a first rod end and a second rod end protruding from the at least one slat; and
a first track defined in a first side of the exercise deck and a second track defined in a second side of the exercise deck;
wherein the first track receives and guides the first rod end, and the second track receives and guides the second rod end, wherein the first rod end and the second rod end are part of a common axle.

2. The treadmill of claim 1 , wherein the first rod end comprises a first low friction element that is shaped to move within the first track, and the second rod end comprises a second low friction element that is shaped to move within the second track.

3. The treadmill of claim 2 , wherein the first low friction element is a first wheel shaped to roll within the first track, and the second low friction element is a second wheel shaped to roll within the second track.

4. The treadmill of claim 2 , wherein the first low friction element is a first bearing shaped to slide within the first track, and the second low friction element is a second bearing shaped to slide within the second track.

5. The treadmill of claim 1 , further comprising a first step in the first track and a second step in the second track, wherein the first step and the second step collectively align the multiple slats of the tread belt.

6. The treadmill of claim 1 , wherein the first track and the second track comprise a curved section spanning between a front section and a rear section of the exercise deck.

7. The treadmill of claim 1 , further comprises an engagement feature formed in an underside of the at least one slat that is configured to rotate a connector.

8. The treadmill of claim 7 , wherein the connector is connected to a flywheel such that as the tread belt moves, the flywheel stores rotational energy that resists changes in a speed of tread belt.

9. The treadmill of claim 7 , wherein the engagement feature is a protrusion formed along a length of the at least one slat.

10. The treadmill of claim 1 , wherein the first track forms a first complete loop in the first side of the exercise deck, and the second track forms a second complete loop in the second side of the exercise deck.

11. The treadmill of claim 1 , wherein the tread belt is movable based on a position of a user on the tread belt.

12. The treadmill of claim 1 , wherein at least two of the multiple slats are joined to the common axle.

13. A treadmill, comprising:
an exercise deck;
a tread belt on the exercise deck comprising multiple slats;
at least one slat of the multiple slats comprising an axle with a first end and a second end;
a first track defined in a first side of the exercise deck and a second track defined in a second side of the exercise deck;
the first track receives and guides the first end of the at least one slat, and the second track receives and guides the second end of the at least one slat;
a first step in the first track and a second step in the second track where the first step and the second step collectively align the multiple slats of the tread belt; and
the first end comprises a first low friction element that is shaped to move within the first track, and the second end comprises a second low friction element that is shaped to move within the second track, wherein the first rod end and the second rod end are part of a common axle.

14. The treadmill of claim 13 , wherein the first low friction element is a first wheel shaped to roll within the first track, and the second low friction element is a second wheel shaped to roll within the second track.

15. The treadmill of claim 13 , wherein the first track and the second track comprise a curved section spanning between a front section and a rear section of the exercise deck.

16. The treadmill of claim 13 , further comprises an engagement feature formed in an underside of the at least one slat that is configured to rotate a connector.

17. The treadmill of claim 16 , wherein the connector is connected to a flywheel such that as the tread belt moves, the flywheel stores rotational energy that resists changes in a speed of tread belt.

18. The treadmill of claim 13 , wherein the first track forms a first complete loop in the first side of the exercise deck, and the second track forms a second complete loop in the second side of the exercise deck.

19. A treadmill, comprising:
an exercise deck;
a tread belt on the exercise deck comprising multiple slats;
at least one slat of the multiple slats comprising an axle with a first end and a second end;
a first track defined in a first side of the exercise deck and a second track defined in a second side of the exercise deck;
the first track forms a first complete loop in the first side of the exercise deck, and the second track forms a second complete loop in the second side of the exercise deck;
the first track receives and guides the first end of the at least one slat, and the second track receives and guides the second end of the at least one slat;
a first step in the first track and a second step in the second track where the first step and the second step collectively align the multiple slats of the tread belt;
the first end comprises a first wheel that is shaped to roll within the first track, and the second end comprises a second wheel that is shaped to roll within the second track, wherein the first rod end and the second rod end are part of a common axle;
the first track and the second track comprise a curved section spanning between a front section and a rear section of the exercise deck;
the tread belt is movable based on a position of a user on the tread belt;
an engagement feature formed in an underside of the at least one slat that is configured to rotate a connector; and
the connector is connected to a flywheel such that as the tread belt moves, the flywheel stores rotational energy that resists changes in a speed of tread belt.
