Abstract:
1. A three-point adjustment multipurpose exercise machine, comprising: a. a frame including a first substantially upright post; b. said first substantially upright post describing a substantially vertical axis; c. a slidable carriage assembly having means to slide and lock on the first substantially upright post along said substantially vertical axis, whereby said slidable carriage assembly describes a first point of adjustment for said machine for adjustment of a vertical height of the slidable carriage assembly along the first substantially upright post; d. a right arm assembly and a left arm assembly, each rotatably, adjustably, and independently mounted to said slidable carriage assembly and each said arm assembly having an axis of rotation, whereby said mounting point of the right arm assembly describes a second point of adjustment for said machine for adjusting the right arm assembly and said mounting point of the left arm assembly describes a third point of adjustment for said machine for adjusting the left arm assembly, the left arm assembly having a left handle unit and the right arm assembly having a right handle unit; e. a resistance assembly; f. at least one cable coupling the left handle unit and the right handle unit and the resistance assembly, wherein there is a tension in the at least one cable; and g. means for keeping the tension in the at least one cable substantially the same, for maintaining the left handle unit at a first distance from the slidable carriage assembly, and for maintaining the right handle unit at a second distance from the slidable carriage assembly when and as the vertical height of the slidable carriage assembly along the first substantially upright post is changed, when and as the left arm assembly is rotated with respect to the first substantially upright post in a manner that causes at least a portion of the at least one cable to move, and when and as the right arm assembly is rotated with respect to the first substantially upright post in a manner that causes at least a portion of the at least one cable to move; and whereby a height and the horizontal span each of the left handle unit and the right handle unit can be adjusted by said three points of adjustments, through sliding the carriage assembly along the first substantially upright post and by pivotably engaging each of the left arm assembly and the right arm assembly with the slidable carriage assembly; further comprising a cable compensator assembly means to maintain the tension in the at least one cable and a constant length of cable for the exercise, whereby, when said carriage and arm assembly are moved upward or downward from any location on the first substantially upright post, said cable compensator assembly travels in the opposite direction and one half of the distance traveled by the carriage and arm assembly, and a cable anchor holds cable compensator assembly in fixed position at any pre-selected height of the carriage and arm assembly and enables cable to transfer resistance from said resistance assembly to the handle units used by exerciser, and whereby said cable compensator assembly compensates both a first half and a second half of the at least one cable at the same time without changing the tension or length of the at least one cable available for exercise.
