Abstract

Claims (14)

1. An exercise device, comprising:

a frame;

a flywheel supported by the frame;

a cable connected to the flywheel, wherein an extension of the cable is configured to rotate the flywheel;

an arm connected to the frame, the arm comprising a pulley system routing the cable to the flywheel;

a pivot connection between the arm and the frame, wherein an angular position of the arm relative to the frame is adjustable about the pivot connection;

a counterweight connected to the arm at the pivot connection, the counterweight counterbalancing the arm about the pivot connection; and

an adjustment mechanism to adjust the angular position of the arm about the pivot connection, the adjustment mechanism comprising:

an adjustment plate comprising a plurality of holes;

an adjustment pin moveable between a closed position and an open position, wherein, in the closed position, the adjustment pin is inserted into one hole of the plurality of holes to lock the angular position of the arm, and wherein, in the open position, the adjustment pin is removed from the one hole of the plurality of holes, the adjustment pin is prevented from moving into the closed position, and the angular position of the arm is adjustable about the pivot connection; and

a locking mechanism comprising a protrusion and a ledge, wherein, in the open position, a contact between the protrusion and the ledge prevents the adjustment pin from moving from the open position to the closed position, wherein the ledge comprises a ramp, and wherein a rotation of the adjustment pin moves the adjustment pin out of the open position.

2. The exercise device of claim 1 , wherein the locking mechanism is located in a cover plate, and wherein the adjustment plate is rotatable relative to the cover plate.

3. The exercise device of claim 1 , wherein the angular position of the arm is a vertical angular position.

4. The exercise device of claim 1 , wherein, when the adjustment pin is in the open position, the arm has a net torque of zero about the pivot connection.
