Abstract

A portable multiple-component articulating support apparatus for engaging, moving, orientating and manipulating a hand-operated power tool within and throughout a three-dimensional workspace. The apparatus includes a clamping device for demountable engagement with a structural element, one or more elongate double-axis hinge member, one or more spacer elements having opposite ends adapted for detachable engagement and rotational communication with the clamping device and the double-axis hinge member, a vertically disposed pivotably connected counterbalance arm assembly adapted for detachable engagement and rotational communication with the double-axis hinge member. The counterbalance arm assembly is equipped with a gas-charged cylinder for balancing the weight of hand-operated power tools. The clamping device, a counterbalance element, one or more spacer elements and one or more double-axis hinge elements alternating therebetween, are interconnected with removable hinge pins. A tool-mounting bracket is provided for grippingly engaging a power tool. The tool-mounting bracket pivotably engages a power tool-bearing member which slidingly and rotatably communicates with the counterbalance arm assembly.
