ERGONOMIC HAND-HELD POWER TOOL AND METHODS OF USE
Abstract:
An ergonomically enhanced electric power tool is disclosed that incorporates a new type of user grip and control system. This grip and control system is housed in a substantially rigid control-housing sheath, which provides enhanced leverage and control over the drilling process while reducing stress on the users hand, wrist, and arm. The tool motor is disposed substantially in parallel with the users wrist, but on a different plane, and eliminates the traditional pistol type of power-tool grip. The control-housing sheath contains a grip-controller assembly that allows the user to control most major drill operations within the gauntlet-like control-housing sheath. The inventive concepts described can be applied to myriad hand-held power tools, and a detailed example for a power drill is provided.
