ABSTRACT:
An auxiliary grip handle and shaft are pivotally connected to a main shaft of an implement to reduce the back and shoulder strain associated with the use of implements, such as garden tools and snow shovels. The implement has the main shaft which is extended, a main grip handle secured thereto and an implement tool fastened to the bottom end of the main shaft. A brace pivotally connects the main shaft to the auxiliary shaft, which has the auxiliary grip handle fastened thereto. When the invention is used with a shovel, the auxiliary shaft is movable from a push position into a pull position. In the push position, the auxiliary shaft is at a small angle relative to the main shaft, enabling the user to apply a forward force on the shovel through both the auxiliary and main grip handles. In the pull position, the auxiliary shaft is at a larger angle in relation to the main shaft, enabling the user to pull upwardly on the auxiliary grip handle to exert a transverse force on the main shaft to lift the shovel. The brace that connects the auxiliary shaft to the main shaft is firmly attached to the main shaft and is secured to the auxiliary shaft by a bolt and a wing nut. Spaced apertures extend through the main shaft to permit repositioning of the brace to accommodate different sized users.
