Abstract

A chest press exercise machine has a self-aligning pivoting user support on a main frame and an exercise arm which is linked to the pivoting user support to translate movement of the exercise arm into movement of the user support. A user support pivot pivotally connects the user support to the main frame. A connecting link is movably associated with the user engagement device or exercise arm and at least one of the main frame, user support, or user support pivot. A user-activated positioning device controls positioning of the exercise arm in an exercise ready position at the start of an exercise. The user support pivot is positioned so that part of the combined weight of the user and user support is positioned on both sides of the gravitational centerline throughout the exercise movement and a portion of the combined weight passes through the centerline to redistribute the weight as the exercise arm is moved.

Claims

1. An exercise machine, comprising:

a main frame having a front end and a rear end;

a user support pivotally mounted relative to the main frame to support a user in an exercise position and moving about a user support pivot axis between a start position and an end position during an exercise movement, the user support having a primary portion and a secondary portion which support spaced positions on a user'"'"'s body throughout an exercise movement, the primary and secondary portions being fixed relative to one another and moving together in the same relative orientation to one another throughout the exercise movement;

at least one exercise arm movably mounted relative to the main frame and having at least one handle for gripping by a user positioned on the user support;

a connecting link which links movement of the exercise arm to movement of the user support;

a load which resists movement of at least one of the user support, exercise arm, and connecting link; and

an exercise arm positioning device which travels with the exercise arm and is pivotally associated with at least one of the main frame and user support, and which controls positioning of the exercise arm in an exercise ready position relative to the user support prior to an exercise movement.

2. The machine of claim 1, wherein the exercise arm positioning device includes a range of motion device pivotally connected between the exercise arm and connecting link, the range of motion device having a first part with a series of spaced holes and a second part comprising a pull pin for releasable engagement in a selected hole, whereby the position of the exercise arm relative to the user support in the exercise ready position is adjusted.

3. The machine of claim 1, wherein the exercise arm positioning device includes a foot engageable cocking mechanism for engagement by a user to move the exercise arm into an exercise ready position.

4. The machine of claim 3, wherein the foot engageable cocking mechanism is associated with the connecting link.

5. The machine of claim 1, wherein the exercise arm positioning device is pivotally associated with the user support whereby adjustment of the positioning device results in movement of the user support.

6. The machine of claim 1, wherein the primary portion of the user support comprises a seat portion which supports a user in a seated position, and the secondary portion comprises a backrest portion.

8. The machine of claim 7, wherein the exercise arm has a rest position in which the handle is located rearward of the exercise ready position and the arm positioning device moves the handle from the rest position to a selected exercise ready position.

9. An exercise machine, comprising:

a main frame having a front end and a rear end;

a user support pivotally mounted relative to the main frame to support a user in an exercise position and moving in an exercise movement between a start position and an end position;

at least one user engagement device movably mounted relative to the main frame and having at least one user engaging portion for engagement by a user positioned on the user support, the user engagement device moving between a start position and an end position during an exercise movement;

a connecting link which links movement of the exercise arm to movement of the user support;

a load which resists movement of at least one of the user support, user engagement device, and connecting link; and

a floating pivot link between the user support and main frame which has a first, fixed pivot connection to the main frame defining a first pivot axis and a second pivot connection to the user support defining a second pivot axis which moves during an exercise movement in a first direction during an initial stage of the exercise movement, and reverses in direction to move in a second, opposite direction during a subsequent stage of the exercise movement up to the end position of the exercise movement.

10. The machine of claim 9, wherein the floating pivot link floats in the same position during part of the exercise movement after the initial stage before reversing in direction to move back in the second direction.

11. The machine of claim 9, wherein the user support has a seat portion and a backrest portion, the seat and backrest portions being fixed relative to one another and moving together in the same relative orientation to one another throughout the exercise movement.

12. The machine of claim 11, wherein the user support has a foot rest portion fixed relative to the seat and backrest portions and moving together with the seat and backrest portions throughout the exercise movement.

13. The machine of claim 9, wherein the connecting link is associated with the exercise arm and is pivotally linked to the user support.

14. The machine of claim 13, further comprising an exercise arm positioning device engageable by a user positioned on the user support to move the exercise arm into an exercise ready position, the exercise arm positioning device being located on the connecting link.

15. The machine of claim 9, wherein the user support is pivotally linked to the main frame at a second location spaced forward from the floating pivot link.

16. The machine of claim 9, wherein the connecting link is connected to the exercise arm and travels with the exercise arm.

17. The machine of claim 9, wherein the floating pivot link is generally V-shaped and has first and second end portions, the first pivot connection located on the first end portion of the connecting link and the second pivot connection located on the second end portion of the connecting link.

18. The machine of claim 17, wherein the user support has a seat pad for supporting a user in a seated position, the first pivot connection is located on the main frame under the user support and the second pivot connection is located on the user support to the rear of the seat pad.

19. The machine of claim 9, wherein the user support has a seat pad for supporting a user in a seated position and a backrest portion for engaging a user'"'"'s back when in a seated position on the user support, and the exercise arm is movable from an exercise ready, start position in which the handle is located at a first position in front of the backrest portion proximate a user'"'"'s chest when seated on the user support, and an end position spaced forwardly from the first position, whereby the combined motion of the user, user support and exercise arm substantially replicates the natural movement of the upper part of a human body when performing a free weight chest press exercise.

20. An exercise machine, comprising:

a main frame having a front end, a rear end, and opposite sides;
