Snow shovel with convex edge

a technology of convex edge and shovel, which is applied in the direction of manufacturing tools, way cleaning, construction, etc., can solve the problems of bringing forward motion and momentum to an abrupt and often painful wrist-jarring and/or gut-jabbing stop, and fragile surfaces are easily damaged, so as to achieve the effect of easy scraping snow

Benefits of technology

[0005] The invention provides a snow shovel having a blade with a convexly-shaped surface located underneath the leading lower edge, which allows the blade to easily scrape snow from rough, unpaved ground as well as other irregular or uneven surfaces. This curved shape, ...

Problems solved by technology

As anyone with experience shoveling snow from rough or uneven surfaces knows, it is difficult and frustrating to do with conventional snow shovels, because the thin, sharp edge of the blade tends to “dig” into the ground or “catch” on protruding ice, nail heads, wood planks, or frozen gravel, bringing forward motion and momentum to an abrupt and often painful wrist-jarring and/or gut-jabbing stop; and when the user attempts to compensate by lowering the shovel shaft, the blade skims up a...

Embodiment Construction

[0015] An embodiment of the invention is shown in FIGS. 1-5. Tool 10 includes an elongate shaft 12 and a blade 14. Shaft 12 is connected to blade 14 via bracket 11 and screw 15 although other conventional means of attachment may be used. Blade 14 includes a backside that is bounded by two side edges, a distal edge 17, and a proximal edge that is closest to the elongate shaft. Blade 14 includes a convex surface 16, which extends (laterally) along the full width of blade 14. The convexly-shaped outside surface of convex surface 16 begins at distal edge 17 of blade 14 and extends upward along the backside of blade 14. Convex surface 16 may be formed integrally with blade 14 or may be separately formed and attached to distal edge 17 of blade 14 as a single piece or as a plurality of pieces. If formed as a plurality of separate pieces, each piece would be attached to distal edge 17 of blade 14 so as to provide a convex surface 16 that extends substantially across the entire width of blad...

Abstract

A shoveling implement (10) includes an elongate shaft (12) attached to a blade (14) having a convexly shaped portion (16) protruding from the backside of the blade adjacent the lower leading (or distal) edge (17), which allows the blade to be easily pushed over rough or uneven surfaces.

Description

FIELD OF THE INVENTION [0001] This invention relates to a snow shovel with a blade having a leading lower edge which is specifically configured to easily scrape snow from rough, unpaved ground as well as other irregular or uneven surfaces. BACKGROUND OF THE INVENTION [0002] In addition to their smoothly paved driveways, many home-owners have to clear snow from other rough or uneven surfaces, such as wood decks, rooftops, and stone, aggregate, or brick walkways or patios. This is especially true in rural areas, where most people have gravel driveways. In the snow-belt regions, farmers, ranchers, construction workers, service people and others must regularly go out into the field and clear snow from rough terrain. As anyone with experience shoveling snow from rough or uneven surfaces knows, it is difficult and frustrating to do with conventional snow shovels, because the thin, sharp edge of the blade tends to “dig” into the ground or “catch” on protruding ice, nail heads, wood planks,...
