Exercise machine with adjustable grip positioning mechanism
First Claim
1. In an exercise machine:
- a horizontally extending platform for receiving a person using the machine, an upstanding post toward one end of the platform, a pair of elongated generally parallel arms pivotally mounted on the post and extending in a lengthwise direction over the platform for movement about a horizontally extending axis, a crossbar affixed to the arms and extending in a horizontal direction parallel to the axis for movement to different heights above the platform as the arms are pivoted about the axis, a first guide mounted in alignment with the axis, a second guide mounted on the crossbar, a cable trained about the guides and adapted to be pulled by the person using the machine, and means connected to the cable for yieldably resisting movement of the cable when a pull is exerted thereon.

Abstract
Exercise machine having a base comprising a horizontally extending platform and an upstanding post. A swing arm comprising has a pair of arms and a crossbar is pivotally mounted on the post for movement about a horizontally extending axis, with the crossbar extending in a direction generally parallel to the axis. A first pair of pulleys are mounted on the base in alignment with the horizontally extending axis, and a second pair of pulleys are mounted on the crossbar. A pair of cables are trained about the pulleys, grips are connected to the cables near the second pulleys, and resistance elements are connected to the cables for yieldably resisting movement of the cables when a pull is exerted thereon. A pair of telescoping arms extend between the base and the crossbar for holding the crossbar and the grips at different heights above the platform.

12. In an exercise machine:
- a base, a swing arm pivotally mounted on the base for movement about a horizontally extending axis, said swing arm having a crossbar with a central portion which is generally parallel to the horizontally extending axis and end portions which extend at an angle from the central portion, a first pair of guides mounted on the base in alignment with the axis, a second pair of guides carried by the swing arm, a pair of cables trained about the guides, means connected to the cables for yieldably resisting movement of the cables when a pull is exerted thereon, grip means connected to the cables near the second guides, the second pair of guides comprising pulleys which are mounted on the end portions of the crossbar and are free to swivel as the cables are pulled in different direction therefrom, and means for holding the swing arm in different positions about the horizontally extending axis to adjust the height o the grip means without changing the tension in the cables.

13. In an exercise machine:
- a horizontally extending platform for receiving a person using the machine, an upstanding post toward one end of the platform, a swing arm extending over the platform in an upward direction from one end of the platform toward the other and being movable about an axis extending transversely of the platform near the one end, said swing arm comprising a pair of arms having inner ends pivotally connected to the post and outer ends positioned above the platform and a crossbar connected to the outer ends of the arms, a headrest mounted on the crossbar, a first guide mounted in a substantially fixed position in alignment with the axis, a second guide carried by the swing arm for movement to different heights above the platform as the swing arm is moved to different positions about the axis, a cable trained about the guides and adapted to be pulled by the person using the machine, and means connected to the cable for yieldably resisting movement of the cable when a pull is exerted thereon.
