Abstract
A snow removal device including a blade having an increasing radius of curvature between the lateral ends of the blade. A planar lower edge contacts the underlying surface and increases in contact area between the blade ends. The snow blade further has a forwardly extending flange at one end thereof so as to bear against a vertical surface adjacent a path such as a curb, building, wall or the like. The blade design forwardly and laterally moves successively increasing amounts of snow during a straight line movement of the blade along the path as well as diverts snow from the vertical surface. The blade is engageable with various handle devices, including a mobile push-type assembly. The assembly includes a handle and blade brace mounted about a wheel axle. A latch maintains the handle in an operative position during use.
Claims2
A snow removal device comprising:
- a mobile handle assembly comprising:
- an axle;
- a wheel rotatably mounted at each end of said axle;
- a brace having first and second arms with a cross arm spanning therebetween, said axle extending between said brace arms for mounting said brace rotatably about the axle;
- and
- a handle rotatably attached to said axle, said handle having first and second arms with said axle extending therethrough for rotatably mounting said handle about said axle;
- a latch attached to one of said handle arms;
- a notch in said latch for engaging said cross arm to restrain rotation of said handle about said axle;
- a snow blade comprising:
- a relatively rigid sheet of material presenting a front face for contact with snow during a movement of said blade along a straight line path of travel;
- said sheet having first and second laterally spaced-apart opposed ends;
- said sheet having a radius of curvature generally increasing from said first end to said second end, said curvature presenting upper and lower edges on said sheet which generally increase in displacement between said first and second ends, said sheet further comprising a lower surface on said sheet generally extending horizontally and forwardly from said lower edge thereof for contact with an underlying surface, said lower surface increasing in area between said first end and said second end of said sheet, whereupon said blade upon straight line movement contacts successively larger portions of snow between said first and second ends during the straight line movement;
- means for attaching said snow blade to said ends of said arms of said brace.
