Abstract

Among other things, a rowing exercise method includes enabling a combination of a force applied to a movable handle and a force applied to a movable foot rest to work against a resistance device and to permit relative motion of the footrest and the resistance device.

Claims

1. A rowing exercise machine comprising

a frame,

a foot support on the frame,

a seat mounted to move along the frame,

a resistance device fixed on the frame,

a handle,

a force transmitting element connecting the handle to the foot support, and

a transfer mechanism connecting the force transmitting element to the resistance device,

the foot support being movable along the frame relative to the resistance device and relative to the handle.

2. The machine of claim 1 in which the force transmitting element comprises a flexible line.

3. The machine of claim 2 in which the flexible line comprises one of a cable, a chain, or a rope.

4. The machine of claim 1 in which the force transmitting element is non-resilient.

5. The machine of claim 1 also comprising a restraining or centering mechanism that urges the seat toward a central location.

7. The machine of claim 1 in which the foot support is mounted to move along the frame.

8. The machine of claim 1 in which the transfer mechanism comprises a flexible line.

9. The machine of claim 8 in which the flexible line include one fixed end and one free end.

10. The machine of claim 9 in which the free end is connected to a slack take-up mechanism.

11. The machine of claim 1 in which the resistance device includes a one-way clutching mechanism coupled to the transfer mechanism.

12. The machine of claim 1 in which the force transmitting element comprises a force transmitting line and the transfer mechanism comprises a first slidable coupling for the force transmitting line.

13. The machine of claim 12 in which the first slidable coupling comprises a first pulley.

14. The machine of claim 13 in which the transfer mechanism comprises a transfer line and the transfer mechanism includes a second slidable coupling for the transfer line.

15. The machine of claim 13 in which the transfer mechanism includes a pulley in which the force transmitting element rides.
