Abstract
An auxiliary handle for use on a hand held implement such as a shovel advantageously provides a molded, unitary frame having hinges molded therein. The auxiliary handle can be precisely positioned for a particular user/implement combination. The frame provides a location where the user grasps the apparatus. The frame is a unitary piece of material which is free from any fasteners, such as nuts and bolts, and which is preferably injection molded from a polypropylene material. The frame includes a middle hinge at substantially at its midpoint so that the frame can assume a any angular orientation between a fully extended linear orientation or can be folded upon itself for shipping and storage. Also provided are end hinges at each end of the frame. Attached to the end hinges, and preferably partially molded therein, are metallic circular clamps which grip the original handle of the implement. The hinges used in the apparatus are molded from a polypropylene material and are of the type known as 'living hinges.' The use of such hinges allows nearly the entire apparatus to be fabricated in one molding step and avoids the difficulties inherent in the use of other types of hinges.
