Abstract

An exercise device includes a resistance unit having a connecting gear. It further includes a cable. It further includes an arm that routes the cable to an actuator. The arm is rotatable relative to the resistance unit about the connecting gear, the arm having a central axis. The arm includes a control that mechanically disengages a locking mechanism from the connecting gear. The control is activated by an activation force substantially directed either toward the central axis of the arm, along a length of the arm, or about the central axis. The activation force is mechanically converted into linear force along the arm that disengages the locking mechanism from the connecting gear.

First claim

What is claimed is:

1. An exercise device, comprising:
a resistance unit having a connecting gear;
a cable; and
an arm that routes the cable to an actuator, wherein the arm is rotatable relative to the resistance unit about the connecting gear, the arm having a central axis;
wherein the arm includes a control that mechanically disengages a locking mechanism from the connecting gear;
wherein the control is activated by an activation force substantially directed either toward the central axis of the arm, along a length of the arm, or about the central axis;
wherein the control comprises a button, wherein the button is activated by pressing down on the button with the activation force substantially directed toward the central axis of the arm;
wherein the activation force is mechanically converted into a linear force along the arm via a wedge coupled to the locking mechanism, and wherein activation of the button causes the wedge to travel in a direction that causes the locking mechanism to disengage from the connecting gear; and
wherein the activation force is mechanically converted into the linear force along the arm that disengages the locking mechanism from the connecting gear.

2. The exercise device of claim 1 , wherein the control is located on a side or a top of the arm.

3. An exercise device, comprising:
a resistance unit having a connecting gear;
a cable; and
an arm that routes the cable to an actuator, wherein the arm is rotatable relative to the resistance unit about the connecting gear, the arm having a central axis;
wherein the arm includes a control that mechanically disengages a locking mechanism from the connecting gear;
wherein the control is activated by an activation force substantially directed either toward the central axis of the arm, along a length of the arm, or about the central axis;
wherein the control comprises a button, where in the button is activated by pressing down on the button with the activation force substantially directed toward the central axis of the arm;
wherein the activation force is mechanically converted into a linear force along the arm that disengages the locking mechanism from the connecting gear;
wherein the activation force is mechanically converted into the linear force along the arm via a gear;
wherein an extension arm is coupled to the gear;
wherein the locking mechanism is coupled to the extension arm; and
wherein activation of the button causes the gear to rotate, disengaging the locking mechanism from the connecting gear.
