Description
Atty. Docket No.: 2025.21609-CA
Patent PLOW BLADE GUARD
Background of the Invention The present invention relates to plow blades and particularly to guard attachments for the blade cutting edge. A traditional snow plow blade includes a cutting edge formed or attached at the lower edge of the plow blade. The function of the cutting edge is to scrape or cut through the snow or ice to remove them from the surface being plowed, such as a road or driveway. The cutting edge is traditionally formed from a hardened piece of steel and is typically attached to the lower edge of the plow blade by way of bolts or the like. Since cutting edges wear over time and need to be replaced, the cutting edge is preferably attached to the plow blade in a manner that permits facile removal. Thus the cutting edge can be replaced as needed while the rest of the plow blade, which is subject to much less wear, has a longer life span.
A typical cutting edge is somewhat sharp and therefore will tend to cut or dig into surfaces that are not sufficiently hard. For example, if the Atty. Docket No.: 2025.21609-CA

Background of the Invention The present invention relates to plow blades and particularly to guard attachments for the blade cutting edge. A traditional snow plow blade includes a cutting edge formed or attached at the lower edge of the plow blade.

The cutting edge is traditionally formed from a hardened piece of steel and is typically attached to the lower edge of the plow blade by way of bolts or the like. Since cutting edges wear over time and need to be replaced, the cutting edge is preferably attached to the plow blade in a manner that permits facile removal. Thus the cutting edge can be replaced as needed while the rest of the plow blade, which is subject to much less wear, has a longer life span.
A typical cutting edge is somewhat sharp and therefore will tend to cut or dig into surfaces that are not sufficiently hard. For example, if the Atty. Docket No.: 2025.21609-CA
snowplow is used on a grassy surface or dirt surface, the cutting edge will cut into the grass or dirt and thereby damage the surface. A similar result may occur when the plow is used on a gravel surface. When used on a gravel surface, a typical cutting edge will tend to push the loose gravel, along with the snow, along the plow path. In these situations, subsequent repair of the grass, dirt or gravel is required due to damage done by a typical plow cutting edge.
Standard cutting edges have also been known to damage surfaces made from brick or paver blocks since the relatively sharp cutting edge has a tendency to chip or break the bricks and blocks. Further, if a surface to be plowed has been coated with paint or an epoxy coating, which is common in parking structures, the plow cutting edge is likely to scrape the paint or coating from the surface. Additional damage may be done to surfaces having speed-bumps or similar structures since the cutting edge is likely to damage these structures as well.
Plow damage to the mentioned environments is costly to repair and further add to annual grounds maintenance since the repairs must be repeated annually after the end of each plowing season. Therefore, there is a need for a device for use in conjunction with a plow blade that will enable the plow to be used in the mentioned plow environments without creating damage to the plowed environment.
Summary of the Invention The present invention allows the user to plow a path on diverse paved or non-paved surfaces without causing damage to the plow, vehicle equipment, or to the ground surface. The present invention Atty. Docket No.: 2025.21609-CA

Summary of the Invention The present invention allows the user to plow a path on diverse paved or non-paved surfaces without causing damage to the plow, vehicle equipment, or to the ground surface. The present invention Atty. Docket No.: 2025.21609-CA
includes a removable plow blade guard having a unique, rounded cross section to therefore allow it and the attached plow to glide across a variety of terrains or obstacles such as rocks or bumps without damage to the underlying terrain. The invention is adapted to fit most manufactured plows and to be easily attached and removed by one individual.
The invention can be fabricated in a variety of sizes to meet user needs. It may be used in conjunction with residential snowplows, commercial snowplows, split plows, wing plows, all terrain vehicle snowplows, tractor plows, and grader blades.
The blade guard of the present invention preferably includes a tubular member having an elongated open slot formed along its top surface.
Optional end caps may be attached at each end of the member. One or more handles may be affixed along the outer surface of the tubular member.
A pair of brackets may be attached to the outer surface of the tubular member with the first end of a chain being connected to each bracket. A buckle or clamp may be connected to the opposite end of each chain.
In use, a plow blade and cutting edge to be used in conjunction with the invention is inserted into the elongated slot. The blade guard is then secured to the plow blade by way of a chain and clamp arrangement which is adapted to attach to an upper portion of the plow blade and/or its frame. The invention can be easily attached by one individual and removed by one individual. One or more handles are attached in locations along the tubular member for easy installation and removal.

The benefit to the user includes the ability to plow a path through the snow using existing plow equipment without causing damage to the plow equipment or the ground surface. This ability allows the user to access areas of property once unavailable during snow cover. Examples of difficult to plow residential areas include: paths to barns or outbuildings during winter months, or access to livestock pens or farm fields.
The invention also allows the user to clear snow from the terrain when the ground is not frozen during early winter and spring months by lessening damage to grassy areas and avoiding time-consuming and costly repairs to the property. Some commercial applications of the invention include use on snowplows used to plow lots with speed bumps, or use on municipal plows having wing plows. Use of the invention on wing plows helps avoid moving gravel on the shoulder of the road or damage to grassy shoulder areas. In addition, the invention may be used on gravel or dirt roadways. The novel blade guard can be used on all terrain vehicles as well as garden or lawn tractors to create a variety of paths for a variety of needs. Residential users can use the invention to plow custom driveways, brick driveways or patios. States and governmental agencies can utilize the device in parts of the United States or Canada with unpaved roadways without causing damage to the ground surface.
