Abstract
A constant force self adjusting cable control device comprising a first member and a second member pivoted to one another about a pivot point, a tension spring connected to the first and second members and yieldingly urging the first and second members in a direction to cause movement about the pivot point and a cable attached to each of the first and second members. The cables are axially aligned such that the axis of the tension spring and the axis of the cables are substantially parallel. The angular displacement between the points of attachment of the spring and the cable and the pivot point on one member forms an angle equal to the angle of the point of attachment of the spring and the cable of the other member and the pivot point whereby substantially constant tension is provided on each of the cables. The device further includes a one-way latch which automatically releases when there is any slack in the cables thereby permitting relative movement between the two members until the tension on the cables is re-established.
