End of travel stop for an exercise device
View Patent ↗An exercise apparatus includes a foot member configured to pivot about a horizontal pivot axis, the foot member supporting a footpad, a first surface coupled to the foot member to pivot with the foot member about the horizontal pivot axis, a second surface stationarily supported by the frame, and a bumper between the first surface and the second surface. The bumper resiliently compresses during pivoting of the first surface in the arc towards the second surface while in contact with the first surface and the second surface.
1. An exercise apparatus comprising:
a frame;
a crank system coupled to the frame, wherein the crank system comprises one or more crank members;
a swing arm operably coupled to the crank system and pivotally coupled to the frame for pivotal movement about a first horizontal axis;
a foot member pivotally coupled to the swing arm about a second horizontal pivot axis, the foot member supporting a footpad;
a first surface coupled to the swing arm to pivot with the swing arm directly about the first horizontal axis;
a second surface stationarily supported by the frame; and
a first bumper between the first surface and the second surface, wherein the bumper resiliently compresses during pivoting of the first surface in the arc towards the second surface while in contact with the first surface and the second surface.
2. The exercise apparatus of claim 1 , wherein the first surface is configured to pivot in a downward arc towards the second surface.
3. The exercise apparatus of claim 2 , wherein the first bumper is configured to provide a non-linear increase in resistance against compression.
4. The exercise apparatus of claim 3 , wherein the first bumper is formed from an elastic material.
5. The exercise apparatus of claim 1 , wherein the first bumper is configured to provide a non-linear increase in resistance against compression.
6. The exercise apparatus of claim 1 , wherein the first bumper is formed from an elastic material.
7. The exercise apparatus of claim 1 further comprising a second bumper configured to be compressed and resist pivotal movement of the first surface and the swing arm prior to the first bumper being compressed.
8. The exercise apparatus of claim 7 , wherein the second bumper is not directly connected to the first bumper.
9. The exercise apparatus of claim 7 , wherein the second bumper is configured to provide a non-linear increase in resistance against compression.
10. The exercise apparatus of claim 7 , wherein the second bumper is configured to be compressed by a third surface operably coupled to the swing arm to move in a first arc in a clockwise direction about a third axis perpendicular to the first axis.
11. The exercise apparatus of claim 10 , further comprising a third bumper configured to be compressed by a fourth surface operably coupled to the swing arm to move in a second arc in a counterclockwise direction about the third axis.
12. The exercise apparatus of claim 1 , wherein the first bumper indicates an end of horizontal travel of the foot member.
13. The exercise apparatus of claim 1 further comprising:
a second swing arm operably coupled to the crank system and pivotally coupled to the frame for pivotal movement about a third horizontal axis;
a second foot member pivotally coupled to the second swing arm about a fourth horizontal pivot axis, the second foot member supporting a second footpad;
a third surface coupled to the second swing arm to pivot with the second swing arm about the third horizontal axis;
a fourth surface stationarily supported by the frame; and
a second bumper between the third surface and the fourth surface, wherein the bumper second resiliently compresses during pivoting of the third surface in the arc towards the fourth surface while in contact with the third surface and the fourth surface.
14. The exercise apparatus of claim 1 , wherein the first horizontal pivot axis extends through the frame.
15. An exercise apparatus comprising:
a frame;
a crank system coupled to the frame, wherein the crank system comprises one or more crank members;
a swing arm operably coupled to the crank system and pivotally coupled to the frame for pivotal movement about a first horizontal axis;
a foot member pivotally coupled to the swing arm about a second horizontal pivot axis, the foot member supporting a footpad;
a first surface coupled to the swing arm to pivot with the swing arm about the first horizontal axis;
a second surface stationarily supported by the frame;
a first bumper between the first surface and the second surface, wherein the bumper resiliently compresses during pivoting of the first surface in the arc towards the second surface while in contact with the first surface and the second surface; and
a second bumper configured to be compressed and resist pivotal movement of the first surface and the swing arm prior to the first bumper being compressed.
16. The exercise apparatus of claim 15 , wherein the second bumper is not directly connected to the first bumper.
17. The exercise apparatus of claim 15 , wherein the second bumper is configured to provide a non-linear increase in resistance against compression.
18. The exercise apparatus of claim 15 , wherein the second bumper is configured to be compressed by a third surface operably coupled to the swing arm to move in a first arc in a clockwise direction about a third axis perpendicular to the first axis.
19. The exercise apparatus of claim 18 , further comprising a third bumper configured to be compressed by a fourth surface operably coupled to the swing arm to move in a second arc in a counterclockwise direction about the third axis.
