Abstract
Abstract This invention is a shovel which enables the user to lift loads with ease, and without suffering back strain. The shovel includes an elongated, curved body, having a first handle protruding from the middle of the body, and a shovel blade at one end. A second handle is located at the other end of the body. A strap is attached to the shovel body, so as to fit over the user's shoulder. One end of the strap is connected to the body near the second handle, and the other end of the strap is fastened to the body at a point between the first handle and the blade. The user grasps both handles, using the first handle to define a pivoting axis for the shovel. The lifting is accomplished by pushing down on the second handle, making the shovel pivot about the first handle. Due to the action of the strap, the user's shoulder supports much of the weight of the load. The first handle is preferably rotatable, relative to the shovel body, so as to facilitate the pivoting motion. The shovel reduces the necessity for bending over while shoveling; most lifting can be done from a standing position. For this reason, the shovel does not cause strain to the back. The shovel may also include a counterweight, mounted near the second handle, which effectively cancels the perceived weight of the shovel blade, allowing the user to lift the load without feeling the weight of the shovel blade.
