  • Patent number: 5906060
    Abstract: An improved manually pushed snow shovel in which the user's natural pushing force acts to alleviate stalling friction. A version of a manually pushed snow shovel having features of this invention comprises a blade with a leading edge, a handle attached to the blade, and at least one, although two are preferred, ski runner(s) attached to the blade. The ski runner(s) are attached such that when in the shovel is in use, the leading edge of the blade is at or behind the portion of bottoms of the ski runner(s) normally in contact with the ground. This ensures that the shovel pivot point or point of downward vertical force from the snow load is forward of the leading edge relative to forward movement of the shovel. As such, the user's natural forward pushing on the handle and hence indirectly to the blade results in the leading edge moving upwards away from the ground upon encountering increased friction due to heavy snow or rough ground surfaces.

  • 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.
