ABSTRACT:
An articulating arm is infinitely adjustable within a pre-determined range. A pivot arm has arcuate surfaces extending therefrom with a brake pivotally mounted to intersect a path of rotation of the arcuate surfaces. Two heat treated shoes provide the arcuate surfaces. The brake is a plate that is controlled to lock or unlock the pivot member relative to a bracket to which the pivot member is pivotally connected. A support is pivotally connected to the pivot member at an end opposite of the bracket. The brake is unlocked manually by forcing the support upward when the support is in a locked position relative to the pivot member.
