Abstract

An exercise machine, having: (a) a frame; (b) a pair of weight stacks connected to opposite sides of the frame; (c) a pair of vertically moveable pulley carriages connected to front portions of the frame; (d) a lifting bar assembly connected to a rear portion of the frame; (e) a pair of arm cables, wherein each of the arm cables are connected to one of the pulley carriages and pass around a first series of pulleys such that the weight stacks are lifted when the arm cables are pulled by a user through the pulley carriages; and (f) a pair of lifting bar cables respectively connected to a pair of vertically moveable bar mounts of the lifting bar assembly that pass around a second series of pulleys such that the weight stacks are lifted when the lifting bar of the lifting bar assembly is raised by the user.

First claim

What is claimed is:

1. An exercise machine including a combined Smith Machine and cable pull exercise machine, the exercise machine comprising:
a frame;
a weight stack mounted on the frame;
a lifting bar with a lifting bar cable connected thereto, wherein the lifting bar is connected to a rear portion of the frame;
an arm cable, wherein a free end of the arm cable is located at a front portion of the frame; and
a transfer pulley assembly, wherein both the lifting bar cable and the arm cable pass around the transfer pulley assembly;
wherein raising the lifting bar causes the lifting bar cable to raise one or more weights on the weight stack, and
wherein pulling on the arm cable causes the arm cable to raise one or more weights on the weight stack.

2. The exercise machine of claim 1 , wherein the lifting bar and the arm cable are independently operable such that movement of either raises the one or more weights on the weight stack.

3. The exercise machine of claim 1 , wherein both the lifting bar cable and the arm cable remain in contact with the transfer pulley assembly during either a lifting bar exercise or an arm pull exercise.

4. The exercise machine of claim 1 , wherein the arm cable passes around a first series of pulleys to lift the one or more weights on the weight stack, and wherein the lifting bar cable passes around a second series of pulleys to lift the one or more weights on the weight stack.

5. The exercise machine of claim 1 , wherein the lifting bar travels along a vertical member, and wherein the lifting bar is positionable in a horizontal direction.

6. The exercise machine of claim 5 , wherein the lifting bar can be locked into position at the rear portion of the frame.

7. The exercise machine of claim 1 , wherein the vertical height of the transfer pulley assembly remains constant when the arm cable is pulled to raise the weight stack.

8. The exercise machine of claim 1 , wherein the vertical height of the transfer pulley assembly changes when the lifting bar cable is pulled to raise the weight stack.

9. The exercise machine of claim 1 , wherein pulling the arm cable and the lifting bar cable an equal distance results in the weight stack moving different distances.

10. The exercise machine of claim 1 , further comprising:
a vertically movable bar mount supporting an end of the lifting bar, and
a vertically movable locking mechanism for setting a bottom height for the vertically movable bar mount.

11. The exercise machine of claim 10 , wherein the vertically moveable locking mechanism comprises:
a vertically moveable lower stop on which the vertically movable bar mount rests;
a pull pin assembly connected to the vertically movable lower stop; and
a frame member having a series of vertical holes dimensioned to receive a pull pin of the pull pin assembly therein.

12. The exercise machine of claim 11 , wherein rotation of the lifting bar releases the pull pin of the pull pin assembly, thereby permitting adjustment of a vertical height of the vertically movable lower stop.

13. The exercise machine of claim 1 , further comprising:
a vertically movable pulley carriage mounted to the front of the frame.

14. The exercise machine of claim 13 , wherein the vertically movable pulley carriage is rotatable around a vertical axis.

15. The exercise machine of claim 1 , wherein a height of the lifting bar can be adjusted without raising the one or more weights on the weight stack.

16. The exercise machine of claim 1 , further comprising:
a pull-up assembly mounted to the front of the frame.
