  • Patent number: 4948188
    Abstract: A snow shovel is presented that requires no bending by the operator and no lifting of snow. The snow-moving elements are blades mounted on pivotally connected elongate handles such that the blades, which are in contact with the ground through a snow layer, are driven apart by a downward and outward motion of the handgrips; this blade motion moves away snow in the path of each of the two blades as they separate. At least a portion of each blade is deflectably mounted to remain in an upright position as sweep motion proceeds, thus no snow accumulates atop the blade.
