STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable to this application.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a plow blade and more specifically it relates to an adjustable plow blade which is adapted to be easily reconfigured between multiple configurations, including a straight-blade configuration and a V-shaped configuration.
2. Description of the Related Art
Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.
Plow blades are utilized on a wide range of vehicles and tool to aid in moving various types of materials. For example, plow blades are commonly used on a tractor for moving debris to various locations. Plow blades are also commonly used on snow-moving tools, such as a handheld snow plow as shown and described in U.S. patent application Ser. No. 13/786,700.
While plow blades have improved over the years, they are generally difficult to connect and disconnected from tools and/or vehicles. Additionally, plow blades are typically comprised of a fixed configuration and are not adjustable into multiple configurations to suit different applications. Where such adjustments are possible, they are often unnecessarily complicated for the common user to perform.
Because of the inherent problems with the related art, there is a need for a new and improved adjustable plow blade which is adapted to be easily reconfigured between multiple configurations, including a straight-blade configuration and a V-shaped configuration.
BRIEF SUMMARY OF THE INVENTION
The invention generally relates to a plow blade which includes a pair of blade portions which are adapted to be removably secured to each other in various configurations including a straight-edge blade configuration and a V-shaped blade configuration. The blade portions each include linkages which may be utilized in connection with fasteners to transition the present invention between the configurations. A mount bar is also provided to which the blade portions are secured to mount the present invention to a plowing object such as a handheld snow plow.

B. Blade Portions.
As shown throughout the figures, the present invention generally comprises a pair of blade portions 20, 40 which are removably secured to each other in various manners to achieve the multiple configurations of the present invention. It should be appreciated that the figures merely illustrate an exemplary configuration for the first blade portion 20 and the second blade portion 40, and thus the scope of the present invention should not be construed as being limited to any particular size, shape, or configuration of the blade portions 20, 40.
As best shown in FIG. 5, the first blade portion 20 comprises a first blade backing 21 comprised of a curved blade configuration having an upper end 22, a lower end 23, a first side 24, and a second side 25. A first slot 26 extends through the first blade portion 20 between its first side 24 and its second side 25 in parallel relationship with the upper and lower ends 22, 23. The first slot 26 receives the first adjustment knob 34 of the first adjustment blade 30 and is utilized to make adjustments thereto.
The first blade portion 20 includes one or more first linkages 27a,b extending from its second side 25 and one or more third linkages 32a,b extending from its first side 24 as shown in FIG. 1 for removably securing the first blade portion 20 to the second blade portion 40 in various configurations as described herein. The first linkages 27a,b are generally positioned on the second side 25 of the first blade portion 20 so as to be connected directly with corresponding second linkages 47a,b on the second side 45 of the second blade portion 40 when the present invention is in its straight-edge configuration. The third linkages 32a,b are positioned on the first side 24 of the first blade portion 20 so as to be connected directly with corresponding fourth linkages 52a,b on the first side 44 of the second blade portion 40 when the blade portions 20, 40 are switched to transition into the V-shaped blade configuration of the present invention.
The first linkages 27a,b may be comprised of various configurations, including the use of clips, brackets, clasps, and the like. In a preferred embodiment as shown in the figures, each of the first linkages 27a,b comprises a cylindrical receiver.

The fourth mount 49 is secured to the mount bar 60 when the present invention is in its V-blade configuration as shown in FIG. 4. Thus, the spacing of the third mount 48 with respect to the first side 44 of the second blade portion 40 is such that the second blade portion 40 may be aligned in a straight-edge configuration when the third mount 48 is connected to the mount bar 60. The spacing of the fourth mount 49 with respect to the second side 45 of the second blade portion 40 is such that the second blade portion 40 may be aligned in the V-blade configuration when the fourth mount 49 is connected to the mount bar 60. The fourth mount 29 includes a flattened portion extending from its lower end which rests underneath the mount bar 60 when in a straight-edge configuration.
C. Mount Bar.
The plowing object 12 will generally include a mount bar 60 to which the present invention may be removably secured in a variety of configurations. The mount bar 60 is best shown in FIG. 1 and generally comprises an elongated member having a first end 61 and a second end 62. The first end 61 of the mount bar 60 includes a first aperture 63 and the second end 62 of the mount bar 60 includes a second aperture 64. A central slot 65 also extends between the first and second ends 61, 62 of the mount bar 60.
D. Operation of Preferred Embodiment.
The present invention is adapted for use with a wide range of plow objects 12, such as tools or vehicles. Tools may include snow blowers, handheld snow plows, and other handheld tools. Vehicles may include tractors, skid steers, bobcats, and the like. In any case, the blade portions 20, 40 are removably secured to the mount bar 60, with the mount bar 60 either being an integral part of or being connected to the plow object 12.
The present invention may be utilized in multiple configurations, including a straight-edge configuration shown in FIG. 2 and a V-shaped blade configuration shown in FIG. 4. To secure the present invention in the straight-edge configuration, the first mount 28 of the first bucket portion 20 and the third mount 48 of the second bucket portion 40 are secured to the first and second apertures 63, 64 of the mount bar 60 via fasteners 14. The second and fourth mounts 29, 49 will rest along the central portion of the mount bar 60 as shown in FIG. 3. The second side 45 of the second blade portion 40 is connected to the second side 25 of the first blade portion 20, such as by linking the first linkages 27a,b to the second linkages 47a,b to connect the blade portions 20, 40 together in the straight-edge configuration as shown in FIG. 3.
To convert into a V-shaped blade configuration, the blade portions 20, 40 are reversed, with the first side 24 of the first blade portion 20 being connected to the first side 44 of the second blade portion 40. When in such a V-shaped blade configuration, the third mount 29 of the first bucket portion 20 and the fourth mount 49 of the second bucket portion 40 are secured to the first and second apertures 64, 64 of the mount bar 60 via fasteners 14.
