Snowplow blade

Abstract

The present invention relates to a snowplow equipped with a shovel supporting devices of movable blade for clearing roads, and of which are provided of a reinforced part member having a shoe arranged thereof, and exceeding the movable blade of at least 1/16 at about 3 inches thick to allow at the time of the operations of snow clearance carried out by the snowplow to generate the fluid deflection of snow, to increase the longevity of the movable blades at the time of the frequent uses, and to prevent breakings at the time of the frequent passages in the holes.

DETAILED DESCRIPTION OF THE INVENTION

Now referring to the accompanying drawings, and in particular to FIGS. 1, 2a and 2b, there is shown in phantom lines a snowplow equipped with a shovel on which is fixed devices of blade (A) using threaded bolts (10) and nuts (12). The movable blade (2) moves on a vertical axis by compression means in order to follow the irregularities of the road.

As illustrated in FIGS. 3a, 3b, 4a and 4b, there is shown a compression spring (6) retained on the movable blade (2) and engaged inside a cavity (13) of a support member (1), and secured by a bolt (7).

As illustrated in FIGS. 4a, 4b and 5, there is shown a movable blade (2) including slip gaps (11) which are intended to receive an eyelet (9) therein, and a bolt (10) therethrough each eyelet (9) and aperture (14) formed therein the support member (1), and secured to the shovel of the snowplow by nuts (12). The eyelets (9) allow the vertical movement of the movable blade (2).

The movable blade (2) includes a reinforced part member (3) having a shoe (4) arranged thereof, and exceeding the movable blades (2) of at least 1/16 at about 3 inches thick to allow at the time of the operations of snow clearance carried out by the snowplow to generate the fluid deflection of snow, to increase the longevity of the movable blades at the time of the frequent uses, and to prevent breakings at the time of the frequent passages in the holes.

More particularly to FIGS. 4a and 4b, there is shown a movable blade (2) in his raised and lowered position.

Accordingly, while the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made in the invention and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.

Claims

1. A snowplow equipped with a shovel on which is fixed devices of blade for clearing roads, wherein the blades move on a vertical axis by compression means, and wherein each device of blade comprising:

a blade provided of a reinforced part member being of a solid alloy and exceeding the blade of at least 1/16 at about 3 inches thick to allow at the time of the operations of snow clearance carried out by the snowplow to generate the fluid deflection of snow.

2. The reinforced part member according to claim 1, characterized in that said reinforced part member is composed of a shoe arranged on each side and exceeding the blade in order to increase the longevity of the blade at the time of the frequent uses, and to prevent breakings at the time of the frequent passages in the holes.

3. The reinforced part member according to claim 2, characterized in that said reinforced part member is assembled to the blade without the contribution of the shoes.

4. The reinforced part member according to claim 2, characterized in that said reinforced part member is assembled to the back face of the blade without the contribution of the shoes.

5. The reinforced part member according to claim 2, characterized in that said reinforced part member having shoes, is assembled to the back face of the blade.
