Benefits of technology

The patent describes a method for making a snow shovel blade by arranging trapezoidal blanks in a way that reduces scrap metal and lowers costs.

Problems solved by technology

Stamped metal blades, however, are limited to shapes that can be formed by the stamping process.
These shapes are generally limited to having curved portion(s) that are either generally parallel or perpendicular to the shovel's longitudinal axis, but not both.
Poly blades can be molded in a wide variety of shapes, but are more expensive than metal blades and, in extreme cold, may become brittle.
These blades are, however, expensive and have the other disadvantages of poly blades.
It is difficult to form a metal blade into a shovel / pusher blade.
When such a deformation is attempted, the metal displaced by the curving and the bending causes undesirable results such as, but not limited to, crumpling (localized distortions) in the sidewalls and tears where the curved portion and the sidewalls intersect.
Such square shovel blades, however, do not include a sufficiently offset back edge or sufficiently angled sidewalls to act as an effective snow shovel / pusher.
Further, aluminum scoops, while having longer curved and bent portions, are still not as effective as desired.
Thus, such blades are generally too planar to act as an effective snow shovel / pusher.

Embodiment Construction

[0019]Directional phrases used herein, such as, for example, clockwise, counterclockwise, left, right, top, bottom, upwards, downwards and derivatives thereof, relate to the orientation of the elements shown in the drawings and are not limiting upon the claims unless expressly recited therein. It is noted that such directional phrases further relate to the position of the snow shovel in use. That is, the forward edge is the edge opposite the handle.

[0020]As used herein, the singular form of “a,”“an,” and “the” include plural references unless the context clearly dictates otherwise.

[0021]As used herein, the term “number” shall mean one or an integer greater than one (i.e., a plurality).

[0022]As used herein, the statement that two or more parts or components are “coupled” shall mean that the parts are joined or operate together either directly or indirectly, i.e., through one or more intermediate parts or components, so long as a link occurs. As used herein, “directly coupled” means t...

Abstract

A snow shovel blade is provided. The snow shovel blade is a stamped metal body with a generally planar portion, a curved portion, and two opposed lateral, depending sidewalls. The sidewalls are supporting sidewalls.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The disclosed and claimed concept relates to snow shovel blades and, more specifically, to a stamped metal snow shovel that includes a pusher portion.[0003]2. Background Information[0004]Devices for moving snow can generally be divided into snow shovels and snow pushers. A snow shovel includes a shovel blade having a substantial length, i.e. a length extending in a direction parallel to the handle. That is, a snow shovel blade generally, but not always, is longer than it is wide. The snow shovel blade allows the user to scoop a quantity of snow. That is, the user slides the snow shovel blade under a quantity of snow, lifts the snow, and deposits the snow at a different location. To effectively accomplish this task, a snow shovel blade often includes sidewalls. That is, the lateral edges of the snow shovel blade are bent upwardly so as to assist in retaining the snow over the snow shovel blade. The rear edge of a snow sh...
