Abstract

An exercise apparatus includes a frame, first and second free pulleys, first and second handle portions, first and second frame pulleys attached to the frame, a central pulley, a pull cord, and a resistance member. The first free pulley includes a first pulley wheel and a first hub with the first pulley wheel configured to rotate in relation to the first hub. The second free pulley includes a second pulley wheel and a second hub with the second pulley wheel configured to rotate in relation to the second hub. The first and second handle portions are in mechanical communication with the first and second hubs with the pulley wheels configured to rotate relative to the handle portions. The pull cord is looped about the pulleys with the resistance member configured to resist movement of the pull cord.

Claims

1. An exercise apparatus comprising:

a frame;

a first free pulley including a first pulley wheel and a first hub with the first pulley wheel configured to rotate in relation to the first hub;

a first handle portion in mechanical communication with the first hub with the first pulley wheel configured to rotate relative to the first handle portion;

a second free pulley including a second pulley wheel and a second hub with the second pulley wheel configured to rotate in relation to the second hub;

a second handle portion in mechanical communication with the second hub with the second pulley wheel configured to rotate relative to the second handle portion;

a first frame pulley attached to the frame;

a second frame pulley attached to the frame;

a central pulley;

a pull cord consecutively looped about the first frame pulley, the first free pulley, the central pulley, the second free pulley and the second frame pulley along the pull cord; and

a resistance member in mechanical communication with the pull cord, the resistance member configured to resist movement of the pull cord with the pull cord being in tension.

2. The exercise apparatus of claim 1 further includes a central pulley locking mechanism configured to engage the central pulley for mitigating movement of the pull cord along the central pulley.

3. The exercise apparatus of claim 2 wherein the central pulley locking mechanism is configured to engage the central pulley via engagement with the pull cord.

4. The exercise apparatus of claim 3 wherein the central pulley locking mechanism includes a cam surface configured to engage the pull cord.

5. The exercise apparatus of claim 2 wherein the central pulley locking mechanism is attached to the central pulley.

6. The exercise apparatus of claim 1 wherein the frame defines a frame longitudinal axis, the exercise apparatus further includes a carriage mounted on the frame and movable along the frame longitudinal axis, the pull cord is attached to the carriage.

7. The exercise apparatus of claim 6 wherein the pull cord includes first and second cord ends that are attached to the carriage.

8. The exercise apparatus of claim 6 wherein the resistance member is attached to the carriage and the frame, the resistance member is configured to resist movement of the carriage along the frame longitudinal axis in a direction towards the first and second frame pulleys.

9. The exercise apparatus of claim 6 wherein the central pulley is attached to the carriage.

10. The exercise apparatus of claim 1 wherein the central pulley is attached to the frame.

11. The exercise apparatus of claim 1 wherein the resistance member includes a plurality of springs.

12. The exercise apparatus of claim 1 wherein the resistance member is a resistance weight, the pull cord includes first and second cord ends that are in mechanical communication with the resistance weight, the resistance weight is configured to resist movement of the first cord end in a direction away from the resistance weight and of the second cord end in a direction away from the resistance weight.

13. A retrofit kit for use with an exercise apparatus, the exercise apparatus including a frame, first and second frame pulleys, and a resistance member, the first and second frame pulleys attached to the frame, the retrofit kit comprising:

a first free pulley including a first pulley wheel and a first hub with the first pulley wheel configured to rotate in relation to the first hub;

a first handle portion in mechanical communication with the first hub with the first pulley wheel configured to rotate relative to the first handle portion;

a second free pulley including a second pulley wheel and a second hub with the second pulley wheel configured to rotate in relation to the second hub;

a second handle portion in mechanical communication with the second hub with the second pulley wheel configured to rotate relative to the second handle portion;

a central pulley; and

a pull cord sized and configured to be consecutively looped about the first frame pulley, the first free pulley, the central pulley, the second free pulley and the second frame pulley along the pull cord, the pull cord being attachable in mechanical communication with the resistance member with the resistance member configured to resist movement of the pull cord with the pull cord being in tension.

14. The retrofit kit of claim 13 further includes a central pulley locking mechanism configured to engage the central pulley for mitigating movement of the pull cord along the central pulley.

15. The retrofit kit of claim 14 wherein the central pulley locking mechanism is configured to engage the central pulley via engagement with the pull cord.

16. The retrofit kit of claim 15 wherein the central pulley locking mechanism includes a cam surface configured to engage the pull cord.

17. The retrofit kit of claim 13 wherein the central pulley locking mechanism is attached to the central pulley.

18. The retrofit kit of claim 13 wherein the frame defines a frame longitudinal axis, the exercise apparatus further includes a carriage mounted on the frame and movable along the frame longitudinal axis, the pull cord is attachable to the carriage.

19. The retrofit kit of claim 18 wherein the pull cord includes first and second cord ends that are attachable to the carriage.
