  • Patent number: 4245411
    Abstract: An improved scoop type snow scraper/lifter has a length to reach at substantially a 45.degree. angle from the ground to the user's hip level, a symmetrical trapezoidal shape with faired-in handgrips at the transverse upper end spaced apart at nominal human hip spacing, these critical dimensions coact with the structure to permit substantially strain-free pushing and scooping of snow by leaning or bumping urging of the unit with the hips which are cushioned by the hands on the handgrips and substantially strain-free lifting of snow scooped, by pivoting the unit on one knee and pressing down on the handgrips to raise the snow and pivot it aside; tapered construction and a spaced pair of skids make the unit less likely to cause injury if broken and quieter in operation.
