Rigid arm pull down exercise machine
First Claim
1. An exercise machine, comprising:
- a main frame having a user support pivot mount, a forward end, and a rear end;
a user support frame pivotally mounted on the user support pivot mount for supporting a user in a seated position facing the forward end of the main frame, the user support frame having a forward end and a rear end and comprising a primary user support which supports a first part of a user'"'"'s body and a secondary user support, the primary user support supporting the majority of a user'"'"'s weight at least in a start position for an exercise, and the secondary user support traveling with the primary user support and not moving relative to the primary user support during an exercise;
the user support pivot mount controlling pivotal movement of the user support frame in a predetermined exercise movement path about a user support pivot axis from an exercise start position to an exercise end position;
a user engagement device movably mounted on one of the frames and adapted for engagement and movement by a user when performing an exercise between a start position and an end position lower than the start position, the user engagement device having a user engaging portion which is located closer to the forward end of the user support frame in the end position than in the start position;
a movable linkage which translates movement of the user engagement device to movement of the user support frame, whereby the user support frame pivots in the exercise movement path from the exercise start position as the user engagement device is moved from the start position; and
a load separate from the user which resists movement of at least one of the moving parts of the machine;
the combined motion of the user support frame and user engagement device during an exercise substantially replicating the natural movement of the upper part of the human body when performing a free bar chin up exercise.

Abstract
An exercise machine for performing lat pull down exercises has a main frame having a user support pivot mount, a user support pivotally mounted on the user support pivot mount for supporting a user in a seated position, and an exercise arm having handles for gripping by a user movably mounted on the frame for movement between a start position located above the head of a user in a seated position on the user support and an end position lower than the start position and generally below the user'"'"'s chin. A connecting linkage connects movement of the exercise arm to movement of the user support. A load resists movement of at least one of the moving parts of the machine. The combined motion of the user support frame and exercise arm substantially replicates the natural movement of the human body when performing a free bar chin up exercise.

24. A lat pull down exercise machine for performing an exercise equivalent to a free bar chin up exercise, comprising:
-
a main frame having a first end and a second end; a user support frame adapted to support a user in an exercise ready position facing the first end of the main frame, the user support frame being pivotally mounted on the main frame for rotation about a user support pivot axis in a predetermined pivotal movement path from an exercise start position to an exercise end position, the user support frame comprising one moving part of the machine; the user support frame comprising a primary user support which supports the majority of a user'"'"'s weight at least in a start position for an exercise, and a secondary user support, the secondary user support traveling with the primary user support and not moving relative to the primary user support as the user support frame moves in said pivotal movement path during an exercise; an exercise arm which is adapted to be used in performing only one type of exercise, the exercise arm being movably mounted on one of the frames for engagement and movement by the user in a first direction in performing exercises, the exercise arm having a user engaging portion, and comprising a second moving part of the machine; a connecting linkage movably engaged with at least two of the main frame, user support frame and exercise arm for linking movement of the exercise arm to movement of the user support frame, whereby movement of the exercise arm from a start position to an end position during an exercise simultaneously rotates the user support frame from the exercise start position to the exercise end position, the connecting linkage comprising a third moving part of the machine; and a load which resists movement of at least one of the moving parts of the machine only when the exercise arm is moved in said first direction, whereby the exercise arm is unidirectional; the combined motion of the user support frame and user engagement arm between the start and end position substantially replicating the natural movement of the upper part of the human body when performing a free bar chin up exercise. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 35)
