Abstract

An exercise apparatus includes a first cord, a second cord, and an adjustment mechanism. The first cord is pullable from and retractable around a first pulley. The second cord is pullable from and retractable around a second pulley. The adjustment mechanism allows for adjusting a pull-out tension provided by the first cord independently of a retraction tension provided by the first cord. The pull-out tension provided by the first cord is a tension provided by the first cord when the first cord is pulled from the first pulley. The retraction tension provided by the first cord is a tension provided by the first cord when the first cord is retracted around the first pulley.

Claims

1. An exercise apparatus, comprising:

a first cord that is pullable from and retractable around a first pulley;

a second cord that is pullable from and retractable around a second pulley; and

an adjustment mechanism for adjusting a pull-out tension provided by the first cord independently of a retraction tension provided by the first cord;

wherein the adjustment mechanism comprises a member with opposing sides that are curved to a tip that is positionable to apply resistance to an outside circumference of the first pulley; and

wherein the pull-out tension is a tension provided by the first cord when the first cord is pulled from the first pulley, and the retraction tension is a tension provided by the first cord when the first cord is retracted around the first pulley.

2. The exercise apparatus of claim 1,

wherein the member of the adjustment mechanism has an asymmetrical shape in which the opposing sides of the member are curved differently from each other to provide a resistance against movement of the first pulley when the first pulley rotates in a first direction and to permit movement of the first pulley when the first pulley rotates in an opposite direction from the first direction.

3. The exercise apparatus of claim 2,

wherein the first pulley is configured to rotate in the first direction when the first cord is pulled from the first pulley, and is configured to rotate in the opposite direction when the first cord is retracted around the first pulley.

4. The exercise apparatus of claim 1, further comprising:

a second adjustment mechanism for adjusting a pull-out tension provided by the second cord independently of a retraction tension provided by the second cord; and

a main body that is a hollow sphere for housing the first pulley and the second pulley, the hollow sphere including a first opening through which the first cord is moveable and a second opening through which the second cord is moveable;

wherein the second adjustment mechanism includes a threaded rod that extends through a third opening in the hollow sphere;

wherein the first opening, the second opening, and the third opening in the hollow sphere are all entirely located in a same hemisphere of the hollow sphere as each other; and

wherein the pull-out tension provided by the second cord is a tension provided by the second cord when the second cord is pulled from the second pulley, and the retraction tension provided by the second cord is a tension provided by the second cord when the second cord is retracted around the second pulley.

5. The exercise apparatus of claim 1,

wherein the adjustment mechanism includes a knob for adjusting a resistance to be applied to the first pulley against rotation of the first pulley in a first direction independent of any adjustment of freedom of movement of the first pulley in an opposite direction from the first direction;

wherein the adjustment mechanism includes a threaded rod attached to the knob that is rotatable to position the member of the adjustment mechanism; and

wherein the adjustment mechanism includes a pin that extends through an opening in the member of the adjustment mechanism in a direction that is perpendicular to a direction that the threaded rod extends from the knob.

6. The exercise apparatus of claim 1, further comprising:

a shaft;

wherein the first pulley and the second pulley are both positioned around the shaft.

7. The exercise apparatus of claim 1, further comprising:

a first shaft; and

wherein the first pulley is positioned around the first shaft, and the second pulley is positioned around the second shaft;

wherein the adjustment mechanism includes a threaded rod connected to a knob that is rotatable to position the member of the adjustment mechanism; and

wherein the threaded rod extends from the knob in a different direction than a direction in which the first shaft extends through the first pulley.

8. The exercise apparatus of claim 1, further comprising:

a main body for housing the first pulley and the second pulley, the main body including a first opening through which the first cord is moveable and a second opening through which the second cord is moveable.

9. The exercise apparatus of claim 8,

wherein the main body is in the shape of a hollow sphere, and the first opening is an opening in an outer surface of the hollow sphere, and the first opening is on an opposite side of the hollow sphere from the second opening.

wherein the exercise apparatus is configured such that the exercise apparatus is mountable on and removable from the mounting device.

14. The exercise apparatus assembly of claim 13,

wherein the mounting device includes a first coupling member for connecting the exercise apparatus to the mounting device and a second coupling member for mounting the mounting device on an object.

15. The exercise apparatus assembly of claim 14,

wherein the mounting device further includes an adjustment member that is moveable to hold the object between the adjustment member and the second coupling member.

16. The exercise apparatus assembly of claim 15,

wherein the adjustment member is located on air opposite side of the second coupling member from the first coupling member.

17. The exercise apparatus assembly of claim 13,

wherein the mounting device comprises a belt for wearing by a user.

18. The exercise apparatus assembly of claim 13,

wherein the mounting device comprises a suction cup for providing suction to an object.
