Abstract

A multipurpose exercise machine requiring only three points of adjustment centrally located. It has a one point height adjustment and two adjustments for the rotating arm assemblies. Dip and chin up bars are attached to the arm assemblies. The machine contains an integrated swingable workout bench. Through the use of a pulley system and counter balance assembly, the cable system maintains tension and provides a constant length of cable.

First claim

I claim:

1. A three-point adjustment multi-purpose exercise machine, comprising:
a frame including an upright post defining an at least substantially vertical axis and a forward horizontal axis;
a sliding carriage assembly slidably mounted on the upright post;
a first locking device configured for releasably locking the sliding carriage assembly at a selected height on the upright post;
a right arm assembly rotatably mounted on the sliding carriage assembly for rotation about one right pivot axis;
a left arm assembly rotatably mounted on the sliding carriage assembly for independent rotation about one left pivot axis spaced from the right pivot axis;
an arm position selector device associated with the sliding carriage assembly;
a second, right arm locking device configured for releasably locking the right arm assembly at a selected rotated position about said right pivot axis;
a third, left arm locking device configured for releasably locking the left arm assembly at a selected rotated position about said left pivot axis;
a right handle unit for engagement by an exerciser associated with an end of the right arm assembly;
a left handle unit for engagement by an exerciser associated with an end of the left arm assembly;
whereby rotation of the right and left arm assemblies about the respective right and left pivot axes adjusts both the height of the handle units and the horizontal span between the handle units;
one or more sources of exercise resistance; and
at least one cable and pulley assembly between the right and left handle units, the sliding carriage assembly, and the one or more sources of exercise resistance, the cable and pulley assembly configured to maintain cable tension independent of adjustment of the vertical position of the sliding carriage assembly or adjustment of the rotated position of the right or left arm assembly about the respective right and left pivot axes.

2. The exercise machine of claim 1 , wherein the right and left arm assemblies each have a respective inner end, the cable and pulley assembly comprises at least one right pulley at the inner end of the right arm assembly and at least one left pulley at the inner end of the left arm assembly, and respective right and left carriage pulleys rotatably mounted on the sliding carriage assembly, with cable extending from the right handle unit along the right arm assembly and around the right pulley and right carriage pulley, and cable extending from the left handle unit along the left arm assembly and around the left pulley and left carriage pulley, the right and left carriage pulleys being oriented parallel to one another and each rotatably mounted about an axis perpendicular to the right and left arm pivot axes.

3. The exercise machine of claim 2 , wherein the spaced right and left pivot axes are not aligned, a cable length extending from the right pulley to the right carriage pulley is substantially aligned with the right arm pivot axis and a cable length extending from the left pulley to the left carriage pulley is substantially aligned with the left arm pivot axis independent of the rotated position of the respective right and left arm assemblies.

4. The exercise machine of claim 2 , wherein the cable and pulley assembly defines a first cable path extending from the right pulley around the right carriage pulley and from the right carriage pulley in a first direction along the upright post and a second cable path extending from the left pulley around the left carriage pulley and in a second direction opposite to the first direction from the left carriage pulley along the upright post.

5. The exercise machine of claim 1 , wherein the cable and pulley assembly comprises one or more cables and a plurality of pulleys defining cable path between each handle unit and the source of exercise resistance, each arm assembly having an outer end and an inner end, and the respective handle unit is linked to a cable end at the outer end of the respective arm assembly, the pulleys including at least one left arm pulley at the inner end of the left arm assembly and one right arm pulley at the inner end of the right arm assembly, and a pair of parallel, left and right carriage pulleys mounted on the sliding carriage assembly and rotatable about the same pivot axis perpendicular to the left and right arm pivot axes, a left length of cable extending along the left arm assembly and around the left arm pulley to the left carriage pulley, a right length of cable extending along the right arm assembly and around the right arm pulley to the right carriage pulley, the cable path between the left arm pulley and left carriage pulley is substantially aligned with the left arm pivot axis and the cable path between the right arm pulley and the right carriage pulley is substantially aligned with the right arm pivot axis independent of the rotated positions of the left and right arm assemblies.

6. The exercise machine of claim 1 , further comprising a swing away bench assembly having a bench configured for selectively supporting a user in a seated position, the swing away bench assembly being pivotally connected to the frame for rotation between a first, operative position in which the bench is located front of the upright post, and a second, storage position in which the bench is spaced to one side of the upright post.

7. The exercise machine of claim 1 , further comprising a right chin-up and dip bar assembly attached to the right arm assembly at a location spaced inward from the right handle unit, and a separate, left chin-up and dip bar assembly attached to the left arm assembly at a location spaced inward from the left handle unit, the right and left chin-up and dip bar assemblies being configured for gripping by a user when performing chin-up or dip exercises.

8. The exercise machine of claim 7 , wherein the right and left chin-up and dip bar assemblies are releasably attached to the respective right and left arm assembly.

9. The exercise machine of claim 7 , wherein the right and left chin-up and dip bar assemblies extend parallel to one another in a forward direction generally parallel to the forward horizontal axis.

10. The exercise machine of claim 1 , wherein each arm assembly is inclined forward at an angle to the upright post.

11. The exercise machine of claim 1 , wherein the right and left pivot axes are non-vertical pivot axes.

12. The exercise machine of claim 11 , wherein the right and left arm assemblies are configured to move in non-parallel planes when rotated about the respective right and left pivot axes.

13. The exercise machine of claim 1 , wherein the sliding carriage assembly comprises a single sliding carriage slidably mounted on a single upright post, and both the right arm assembly and the left arm assembly are rotatably mounted on the single sliding carriage.
