Fitness equipment unit
View Patent ↗A fitness equipment unit includes a member rotatable about an axis and a source of resistance against rotation of the member. Rotation of the member is facilitated by pulling on a first end of the line while the other end of the line is stationary, pulling on a second end of the line while the first end is stationary or concurrently pulling on both the first end and the second end of the line.
1. A fitness equipment unit comprising:
a member rotatable about an axis;
a source of resistance against rotation of the member about the axis;
a first arm;
a second arm movable independent of the first arm;
a guide carried by the member to rotate about the axis; and
a single line having a first portion connected to the first arm and a second portion connected to the second arm, wherein the single line extends about the guide such that movement of the first arm with the second arm being stationary, movement of the second arm with the first arm being stationary or movement of both the first arm and the second arm rotates the member about the axis against the source of resistance.
2. The fitness equipment unit of claim 1 , wherein the guide comprises a pulley.
3. The fitness equipment unit of claim 2 further comprising a second pulley on a first side of the member and a third pulley on a second side of the member, wherein the single line extends about the second pulley, about the pulley and about the third pulley.
4. The fitness equipment unit of claim 3 , wherein the second pulley and the third pulley are rotatable about the axis.
5. The fitness equipment unit of claim 3 , wherein the member comprises a fourth pulley and further comprising a second line operably coupling the fourth pulley to the source of resistance.
6. The fitness equipment unit of claim 5 , wherein the pulley is between the second pulley and the third pulley and in front of the fourth pulley.
7. The fitness equipment unit of claim 3 , wherein the single line extends over the axis while engaging the second pulley and the third pulley and wherein the single line extends below the axis when extending from the member such that the pulley rotates about the axis in a direction over the axis in response to movement of the first arm, the second arm or both the first arm and the second arm.
8. The fitness equipment unit of claim 3 , wherein the pulley is between the second pulley and the third pulley and in front of the member.
9. The fitness equipment unit of claim 1 , wherein the member comprises a pulley and wherein the fitness equipment unit further comprises a second line operably coupling the pulley to the source of resistance.
10. The fitness equipment unit of claim 1 , wherein the member is crescent shaped.
11. The fitness equipment unit of claim 1 further comprising a second line having a first end connected to the member and a second end connected to the source of resistance.
12. The fitness equipment unit of claim 11 , wherein the second line wraps at least partially about the member during rotation of the member.
13. The fitness equipment unit of claim 1 , wherein the source of resistance comprises a stack of weights.
14. The fitness equipment unit of claim 1 , wherein the first arm and the second arm are independently pivotable.
15. The fitness equipment unit of claim 14 , wherein the first arm and the second arm are independently pivotable about a horizontal axis.
16. A fitness equipment unit comprising:
a stack of weights;
a first arm;
a second arm movable independent of the first arm;
a first pulley rotatable about an axis;
a second pulley carried by the first pulley to rotate about the axis;
a third pulley on a first side of the first pulley;
a fourth pulley on a second side of the first pulley;
a first line having a first end portion connected to the first pulley and a second end portion operably coupled to the stack of weights; and
a second single line having a first portion connected to the first arm and a second portion connected to the second arm, wherein the second single line extends about the third pulley, about the second pulley and about the fourth pulley such that movement of the first arm being stationary, movement of the second arm with the first arm being stationary or movement of both the first arm and the second arm rotates the member about the axis to pull the first line.
17. The fitness equipment unit of claim 16 , wherein the third pulley and the fourth pulley are rotatable about the axis.
18. The fitness equipment unit of claim 16 , wherein the second pulley is between the third pulley and the fourth pulley and in front of the first pulley.
19. The fitness equipment unit of claim 16 , wherein the second single line extends over the axis while engaging the third pulley and the fourth pulley and wherein the first line extends below the axis when extending from the first pulley such that the second pulley rotates about the axis in a direction over the axis in response to movement of the first arm, the second arm or both the first arm and the second arm.
20. The fitness equipment unit of claim 13 , wherein the first arm and the second arm are independently pivotable.
21. The fitness equipment unit of claim 1 , wherein the member comprises a first pulley, the fitness equipment unit further comprising a second pulley on a first side of the member and a third pulley on a second side of the member, wherein the single line extends about the second pulley, about the first pulley and about the third pulley and wherein the first pulley, the second pulley and the third pulley are parallel.
22. The fitness equipment unit of claim 3 , wherein the third pulley is rotatable about a second axis nonparallel to a third axis about which the line turns about the guide.
23. The fitness equipment unit of claim 16 , wherein the third pulley and the fourth pulley rotate about a second axis that is parallel to a third axis about which the second pulley is rotatable.
24. A fitness equipment unit comprising:
a member rotatable about an axis;
a source of resistance against rotation of the member about the axis;
a first arm;
a second arm movable independent of the first arm;
a guide carried by the member, wherein the guide comprises a first pulley; and
a line having a first portion connected to the first arm and a second portion connected to the second arm, wherein the line extends about the guide such that movement of the first arm with the second arm being stationary, movement of the second arm with the first arm being stationary or movement of both the first arm and the second arm rotates the member about the axis against the source of resistance; and
a second pulley on a first side of the member and a third pulley on a second side of the member, wherein the line extends about the second pulley, about the first pulley and about the third pulley, wherein the line extends over the axis while engaging the second pulley and the third pulley and wherein the line extends below the axis when extending from the member such that the first pulley rotates about the axis in a direction over the axis in response to movement of the first arm, the second arm or both the first arm and the second arm.
