Exercise machine with pivoting user support and multiple cam linkage
First Claim
1. An exercise machine, comprising:
- a floor-engaging main frame;
a user support frame pivotally mounted relative to the main frame for rotation about a user support pivot axis, the user support pivot axis defining a vertical, gravitational center line;
the user support frame having at least a primary support and a secondary support for supporting spaced positions on a user'"'"'s body throughout an exercise movement, the secondary support being fixed at a predetermined angular orientation relative to the primary support, the primary support supporting the majority of a user'"'"'s weight in the start position of the support frame;
a user engagement device movably mounted relative to the frames which is engaged by the user in performing exercises;
a connecting linkage which translates movement of the user engagement device to movement of the user support frame;
the connecting linkage having first and second cam winding portions rotatable about a common cam axis and axially spaced along the common cam axis, a first flexible link connected for winding about the first cam winding portion and a second flexible link connected for winding about the second cam winding portion; and
a load for resisting movement of at least one of the user support, user engagement device, and connecting linkage.

Abstract
An exercise machine has a main frame and a user support frame pivotally mounted relative to the main frame for rotation about a user support pivot axis between start and end positions. The user support frame has at least a primary support and a secondary support for supporting spaced positions on a user'"'"'s body throughout an exercise movement. A user engagement device is movably mounted relative to the frames for engagement by the user in performing exercises, and an at least partially flexible connecting linkage translates movement of the user engagement device to rotational movement of the user support frame. The connecting linkage includes at least two axially spaced winding portions mounted for rotation about a common cam axis. A load resists movement of at least one of the user support, user engagement device, and connecting linkage.

10. An exercise machine, comprising:
-
a floor-engaging main frame; a user support frame pivotally mounted relative to the main frame; the user support frame having at least a primary support and a secondary support for supporting spaced positions on a user'"'"'s body throughout an exercise movement, the secondary support being fixed at a predetermined angular orientation relative to the primary support, the primary support supporting the majority of a user'"'"'s weight in the start position of the support frame; a user engagement device movably mounted relative to the frames for engagement by the user in performing exercises; a multiple part connecting linkage which translates movement of the user engagement device to movement of the user support frame; the connecting linkage having at least two axially spaced cam winding portions rotatable about a common cam axis, a first flexible elongate member connected for winding about the first cam winding portion and associated with the user engagement device, and a second flexible elongate member connected for winding about the second cam winding portion and associated with the user support frame, whereby movement of the user engagement device to perform an exercise reeves one flexible elongate member around the respective cam winding portion so that the user support frame moves from a start position to an end position; and a load for resisting movement of at least one of the user support, user engagement device, and connecting linkage. - View Dependent Claims (11, 12, 13)

20. An exercise machine, comprising:
-
a floor-engaging main frame; a user support frame; a pivot assembly pivotally mounting the user support frame which allows rotation of the user support frame relative to the main frame between a start position and an end position, the pivot assembly having at least one pivot and defining a vertical gravitational center line of the pivotal movement of the user support frame; the user support frame having at least a primary support and a secondary support for supporting spaced positions on a user'"'"'s body throughout an exercise movement, the secondary support being fixed at a predetermined angular orientation relative to the primary support, the primary support supporting the majority of a user'"'"'s weight in the start position of the support frame; a user engagement device movably mounted relative to the frames and engaged by the user in performing exercises; an at least partially flexible connecting linkage which translates movement of the user engagement device to rotational movement of the user support frame, the connecting linkage comprising at least one cam device mounted for rotation about a cam axis and having at least a first winding portion and at least a first flexible link associated with the cam winding portion; and a load for resisting movement of at least one of the user support, user engagement device, and connecting linkage. - View Dependent Claims (21, 22, 23, 24, 25)
