Abstract

A hook assembly may comprise a base portion and at least one hook. The base portion may be rotatably coupled to a weighted cable of an exercise machine. The at least one hook may be coupled to the base portion, and the at least one hook may be sized and configured for selective attachment to a handle. The base portion may be sized and configured to facilitate rotation of the at least one hook relative to a frame of an exercise machine when the weighted cable is extended. Additionally, the base portion may be sized and configured to prevent rotation of the at least one hook relative to the frame of the exercise machine when the weighted cable is fully retracted.

First claim

What is claimed is:

1. An exercise machine, comprising:
a frame;
a weighted cable routed through the frame;
an adjustable weight source connected to the weighted cable configured to provide a resistance force on the weighted cable; and
at least one hook assembly located on the weighted cable, the at least one hook assembly comprising:
a base portion rotatably coupled to the weighted cable; and
at least one hook coupled to the base portion, the at least one hook sized and configured for selective attachment to a handle; and
wherein the base portion is sized and configured to facilitate rotation of the at least one hook relative to the frame when the weighted cable is extended by a pull force that overcomes the resistance force; and
wherein the base portion comprises a tapered shoulder configured to insert into a cable routing structure attached to the machine such that the resistance force imposed on the weighted cable by the adjustable weight source provides a mechanical interference between the base portion and the frame that prevents rotation of the at least one hook relative to the frame when the weighted cable is fully retracted to maintain the handle in a fixed position with respect to the frame to facilitate removal of the handle from the hook portion.

2. The exercise machine of claim 1 , wherein the at least one hook assembly further comprises a retaining member configured to cooperate with the at least one hook to selectively prevent removal of the handle from the at least one hook.

3. The exercise machine of claim 2 , wherein the retaining member is biased to a locked position.

4. The exercise machine of claim 2 , wherein the retaining member comprises a shaped wire.

5. The exercise machine of claim 2 , wherein the retaining member comprises an annular sleeve.

6. The exercise machine of claim 2 , wherein the retaining member comprises an extending lever configured to facilitate rotation of the retaining member relative to the at least one hook.

7. The exercise machine of claim 1 , wherein the at least one hook comprises a first hook hingably coupled to the base and a second hook hingably coupled to the base, the first hook and the second hook configured to interlock.

8. The exercise machine of claim 1 , wherein the handle comprises an enlarged end portion and wherein the at least one hook comprises a channel shaped to slidably receive the enlarged end portion and prevent longitudinal movement of the enlarged end portion relative to the hook when the enlarged end portion is positioned within the channel.

9. The exercise machine of claim 8 , wherein the at least one hook assembly further comprises a spring biased sleeve sized and configured to selectively lock the enlarged end within the channel of the hook.
