Exercise device ramp roller retainer

1. An exercise device comprising:

a first member configured to be reciprocatively driven by one or more feet;

a user adjustable resistance supply operatively coupled to the first member;

a first roller rotationally coupled to the first member;

a first projection carried by the first roller to move with the first roller, the first projection extending away from the first roller; and

a roller guide comprising:

a first inclined floor underlying the first roller; and

a first overhang extending over the first projection opposite a first side of the first roller, wherein the first roller and the first projection carried by the first roller are movable relative to the guide between a first position in which the first overhang contacts the first projection to limit movement of the first roller and a second position in which the first overhang is out of contact with the first projection.

2. The exercise device of claim 1 , wherein the first inclined floor and the first overhang are integrally formed as part of a single unitary body.

3. The exercise device of claim 1 , wherein the roller guide includes a first side wall extending upwardly from the first inclined floor along the first side of the first roller opposite to the first projection.

4. The exercise device of claim 3 , wherein the first roller guide includes a second side wall extending upwardly from the first inclined floor along a second opposite side of the first roller.

5. The exercise device of claim 4 , wherein the first inclined floor, the first overhang, the first side wall and the second side wall are integrally formed as part of a single unitary body.

6. The exercise device of claim 5 further comprising:

a second member configured to be driven by one or more feet;

a second roller rotationally coupled to the second member;

a second projection carried by the second roller to move with the second roller, the second projection extending away from the second roller along a rotational axis of the second roller; and

a second roller guide comprising:

a second inclined floor underlying the second roller; and

a second overhang extending over the projection opposite a first side of the second roller, wherein the second roller and the second projection carried by the second roller are movable relative to the second guide between a third position in which the second overhang contacts the second projection to limit movement of the second roller and a fourth position in which the second overhang is out of contact with the second projection.

7. The exercise device of claim 6 , wherein the first member has a first portion coupled to the first roller and a second portion configured to rotate in a circle about an axis.

8. The exercise device of claim 6 further comprising a first swing arm coupled to the first member and configured to move with movement of the first member and a second swing arm coupled with a second member configured to move with movement of the second member.

9. The exercise device of claim 6 , wherein the second roller guide includes a third side wall extending upwardly from the second inclined floor along the first side of the second roller opposite to the second projection.

10. The exercise device of claim 9 , wherein the second roller guide includes a fourth side wall extending upwardly from the second inclined floor along a second opposite side of the second roller.

11. The exercise device of claim 10 , wherein the second inclined floor, the second overhang, the third side wall and the fourth side wall are integrally formed as part of a single unitary body.

12. The exercise device of claim 1 further comprising a yoke rotationally supporting the first roller relative to the first member, wherein the yoke extends between the first roller and the first projection.

13. The exercise device of claim 1 further comprising:

a yoke coupled to the first member;

a roller bearing coupled to the first roller; and

a fastener connecting the first projection and the roller bearing to the yoke.

14. The exercise device of claim 1 , wherein the first member has a first portion coupled to the first roller and a second portion configure to rotate in a circle about an axis.

15. The exercise device of claim 1 further comprising a swing arm coupled to the first member and configured to move with movement of the first member.

16. The exercise device of claim 1 further comprising:

a second member configured to be driven by one or more feet;

a second roller rotationally coupled to the second member;

a second projection extending away from the second roller; and

a second roller guide comprising:

a second inclined floor underlying the second roller; and

a second overhang extending over the projection opposite a first side of the second roller.

17. The exercise device of claim 1 , wherein the first projection extend along a rotational axis of the first roller.

18. A method comprising:

reciprocatively moving a first member of an exercise device along a first ramp by rolling a first roller along a first roller guide;

lifting the first roller out of contact with the first ramp during use of the exercise device; and

retaining the first roller along the first roller guide while the first roller is lifted out of contact with the first ramp during use of the exercise device with a first overhang capturing and temporarily contacting a first projection extending from a first roller along a rotational axis of the first roller.

19. The method of claim 18 further comprising pivoting a swing arm coupled to the first member in unison with movement of the first member.

20. The method of claim 18 further comprising:

moving a second member along a second ramp by rolling a second roller along a second roller guide; and

retaining the second roller along the second roller guide with a second overhang capturing a second projection extending from a second roller along a rotational axis of the second roller.

21. The method of claim 18 further comprising rotating a portion of the first member in a circle about an axis.

22. The exercise device of claim 1 , wherein the first roller has a top spaced out of contact with other structures.

23. The exercise device of claim 1 further comprising a crank mechanism operatively coupled to the first member.
