The accumulation surface may be attached to a support shaft which may include an additional handle to produce a manually operated snow shovel. Alternatively, a bracket mounted to the inward facing surface of the V shaped plow may connect the snow removal device to a granular spreader apparatus. The V shaped plow may include a deflector, of various shape, integrally attached at the leading apex of the plow. Additionally, the outward facing surface of the V shaped plow may utilize a concave shape that may increase along a gradient as it gets closer to the distal ends of the plow and/or as it gets closer to the top edge or the bottom edge of the plow.
Description
- The present invention relates generally to a snow removal device for removing snow from walkways and other pathways. More specifically, the present invention relates to a snow removal device with a V shaped plow. The preferred embodiment of the present invention utilizes an accumulation surface used in conjunction with a V shaped plow for plowing and compacting snow.
- Residents that live in colder climates are well aware of the hazards that result from snow fall accumulation. Accumulation of snow on walkways, driveways, streets, and other paths can lead to slippery surfaces that are hazardous to drive and/or walk on. Many colder climate residents utilize snow removal devices, like snow shovels, to remove accumulated snow from pathways to avoid the aforementioned hazards.
- Traditional snow shovels are comprised of a wide, relatively flat surface, usually made of metal or plastic, at the bottom end of the shovel and a handle at the top end. The two pieces are attached by a shaft of varying length, traditionally made of wood or plastic. Users grip the handle with one hand and may grip the shaft of the shovel with their other hand for additional leverage. The user can then push the handle of the snow shovel to correspondingly push the flat surface below a buildup of snow, typically at an angle to the pathway below. Once the snow is resting on the flat surface, the user may lift the handle and shaft to move the snow from the pathway to another location. Users experience strain on their arms and backs due to the repetitive lifting of the snow shovel with the added weight of the built-up snow. This can lead to unnecessary strain and even injury, especially in light of the cold climate associated with the activity and if proper lifting techniques are not used. Additionally, the strain involved with the activity worsens the longer the activity is undertaken which is usually directly correlated to the size of the area to be cleared and the physical health of the user.
- Other types of devices are also used to clear snow, namely plows that push snow from one area to another. A typical plow comprises a wide, substantially vertical piece of metal, plastic or other stiff material. This plow piece can be attached to numerous devices and can also take on multiple shapes. A plow may be connected to a handle to allow a user to manually push snow out of a pathway or it may be attached to a vehicle. The plow can take the shape of a straight, wide plow or variously angled, V shaped plows. As the plow is pushed through snow, snow accumulates at the front of the plow and adds resistance to the user or vehicle pushing the device and accumulated snow. Additionally, if a plow is not substantially perpendicular to the pathway it is meant to clear and is not in contact with the pathway along the lower edge, the plow will not be as effective in clearing snow from the pathway. Again, plows, specifically manual plows, can come with some of the same health risks as traditional snow shovels.
- U.S. patent application Ser. No. 10/861,413 to Fortino discloses a V shaped, manually-operated plow with a small shovel blade mounted facing opposite the V shaped plow. The user is able to push the snow away as with a typical plow and then is directed to drag the Fortino device backwards to clear any remaining snow using the small shovel blade.
- U.S. patent application Ser. No. 14/618,325 to Fernandez, Sr. discloses a convertible plow that can move from a substantially straight bladed plow to a V shaped plow. The convertible bottom blade is attached to a shaft that allows each piece of the blade to move from a straight to a V shaped configuration. The shaft is connected to a secondary shaft which is attached to one or more handles to allow for manual operation.
- U.S. Pat. No. 3,436,847 to Marion discloses a V shaped plow blade that is attachable to a garden tractor. The plow blade is adjustable in height and includes ground engaging shoes in the center and outer lower ends of the plow to adjustably secure the blade.
- U.S. Pat. No. 4,255,884 to Williams discloses a V shaped plow that can be attached to the front of the bucket of a front end loader. The blade allows a user of the front end loader to attach or detach the plow without dismounting from the front end loader.
- PCT Patent Application Number PCT/GB2012/000576 to Lloyd et al. discloses a manually operated snow plow with a chipper blade attached to the bottom portion of the V shaped plow blade. Furthermore, Lloyd et al. describes a wheel assembly mounted behind the plow that allows the device to roll.

Additionally, Schbot discloses a height adjustable shaft connected to a handle on one end and the plow blade on the other.
- None of the prior art devices provide a means for inserting plow blades at an angle and effectively channeling snow toward the plow using an accumulation surface. Accordingly, there is a need in the art for an improved snow removal device that utilizes a V shaped plow attached to an accumulation surface. The integration of an accumulation surface with a V shaped plow, such as in the current invention, eases the effort required by a user as well as more effectively clears a path without the need for repetitive passes as with a traditional plow.
- The present invention provides an improved snow removal device for more easily and effectively moving snow from a pathway. An embodiment of the present invention provides an accumulation surface for receiving snow that also includes a V shaped plow integrally attached and extending from the accumulation surface. The accumulation surface may be attached to a shaft, with or without an additional handle at the opposite end, or it may be attached to a granular spreader apparatus. Additionally, when the present invention is utilized with a granular spreader apparatus it is anticipated that the device can be used with or without an accumulation surface.
- The V shaped plow of the present invention is composed of two sections in the preferred embodiment. Each section comprises an upper edge, a lower edge, a proximal edge, a distal edge, an outward facing surface, and an inward facing surface. Each section is integrally attached at the proximal edge to form the V shaped plow of the preferred embodiment. The integrally attached proximal edges also form the leading apex of the V shaped plow of the present invention. Additionally, a bracket can be included to reinforce and/or create an attachment point. The bracket is integrally attached to the inward facing surface of one or more sections and can act as the attachment point for a granular spreader apparatus and/or to reinforce the sections of the V shaped plow to better hold its overall shape as it is pushed through the snow.
- It is contemplated that the angle of attachment for the sections can vary depending on the size and anticipated need of the device. The preferred embodiment of the V shaped plow also comprises a concave surface between the upper and lower edges of each section on the outward facing surface. The curvature of the concave surface can be emphasized at the bottom or the top of each section of the V shaped plow. For example, if the lower curvature is emphasized, then the lower edge of the sections of the V shaped plow will extend further in front of the plow compared to the upper edge. Conversely, if the upper curvature is emphasized, then the upper edge of the sections of the V shaped plow will extend further in front of the plow compared to the lower edge.
- Embodiments of the present invention also utilize a V shaped plow with a deflector included and integrally formed with the leading apex of the V shaped plow. The first edge of the deflector inversely compliments the shape of and is integrally formed with the leading apex of the V shaped plow. The second edge of the deflector can be shaped so as to produce either a straight, convex, or concave edge between the upper and lower edges of the V shaped plow at the leading apex.
- The present invention decreases the amount of effort and time needed to clear a pathway of accumulated snow. This is accomplished by pairing a V shaped plow with the accumulation surface base of a traditional snow shovel and/or a granular spreader apparatus. The accumulation surface allows the users to insert the accumulation surface at an angle to the snow and pathway below which channels the snow toward the plow to push it out of the way. Accordingly, the user does not need to excerpt as much effort to angle the plow properly to stay substantially in contact with the pathway below the accumulated snow. This allows the user to save time and energy when clearing pathways of snow. The snow removal device of the present invention can also reduce the risk of injury to the user due to the decreased effort required, thus reducing the risk of improper use.
- It is therefore an object of the present invention to provide a new and improved snow removal device that reduces the amount of effort needed by the user, and correspondingly the risk of injury to the user, to clear snow from a pathway.
- Another object of the present invention is to provide a new and improved snow removal device that reduces the amount of time needed by the user to clear snow from a pathway.
- Another object of the present invention is to provide a new and improved snow shovel that includes an accumulation surface, that can cut into accumulated snow, which is connected to a V shaped plow, that can simultaneously push snow from a path.
- Yet another object of the present invention is to provide a new and improved snow removal device that interfaces with a granular spreader apparatus, such as a salt spreader, so that a user can remove snow and spread salt on a pathway at the same time.
- Other objects, features, and advantages of the present invention will become apparent from the detailed description below in light of the accompanying figures.

Additionally, thesnow removal device 100 of the present invention clears snow from a pathway more efficiently compared to prior art, manually operated snow removal devices. - Referring to
FIG. 1 , shown is a perspective view of the preferred embodiment of the present invention. The preferred embodiment of thesnow shovel 130 depicted inFIG. 1 utilizes atraditional handle 128 connected to one end of a support shaft. However, it should be appreciated by one skilled in the art that various handle shapes can be utilized or that the support shaft can act as thehandle 128 of thesnow removal device 100 without departing from the scope of the present invention. The other end of the support shaft of thesnow shovel 130 is connected to the snow removal device of thepresent invention 100. The support shaft is connected to one end of theaccumulation surface 102 of the present invention. It is anticipated that theaccumulation surface 102 can take many shapes, such as rectangular or square, as well as various dimensions without departing from the scope of the present invention. A V shapedplow 105 extends from or is integrally connected with theaccumulation surface 102. The connection may occur through the use of abracket 122 as depicted inFIG. 1 . The V shapedplow 105 of the preferred embodiment of the present invention is composed of a firstrigid section 103 and a secondrigid section 104. Eachsection upper edge 106, alower edge 108, aproximal edge 110, adistal edge 112, an outward facingsurface 114, and an inward facingsurface 116. The twosections proximal edges 110 at an angle to create the V shapedplow 105 shape as well as form theleading apex 118 of the V shapedplow 105. Additionally, anoptional deflector 124 may be utilized as depicted inFIG. 1 . Thedeflector 124 comprises two edges, afirst edge 125 and asecond edge 126. Thefirst edge 125 of thedeflector 124 is integrally formed and connected with theleading apex 118 of the V shapedplow 105. Thesecond edge 126 of thedeflector 124 creates a deflecting edge that can take various forms between theupper edge 106 andlower edge 108 of the V shapedplow 105. It is anticipated that thedeflector 124 could produce a straight edge, convex edge, or concave edge between theupper edge 106 andlower edge 108 of the V shapedplow 105. - Turning to
FIG. 2 , a perspective view of an alternative embodiment of thesnow removal device 100 of the present invention is shown. In this embodiment, the V shapedplow 105 is connected to agranular spreader apparatus 132. Anexemplary apparatus 132 used in conjunction with the V shapedplow 105 of the present invention is a manually operated salt spreader so that a user may simultaneously clear pathways of accumulated snow and spread salt to aid in preventing the accumulation of additional snow and/or ice. However, it should be appreciated by one skilled in the art that any type of granular spreader apparatus 132 (for example, powered or manually operated) may be utilized without departing from the scope of the present invention. Thegranular spreader apparatus 132 is attached to the V shapedplow 105 via thebracket 105 attached to the inward facingsurface 116 of one ormore sections plow 105. Although it should be appreciated by one skilled in the art that other attachment points can be utilized without departing from the scope of the present invention. The first andsecond sections proximal edges 110 to form theleading apex 118 of the V shapedplow 105. It is anticipated that anaccumulation surface 102 that is relatively perpendicular to the V shapedplow 105 may be utilized to further enhance thesnow removal device 100 depicted inFIG. 2 . An accumulation surface would be attached to thelower edge 108 of the V shapedplow 105. - A
deflector 124 integrally attached to theleading apex 118 is also shown inFIG. 2 . Thedeflector 124 comprises of two edges, afirst edge 125 that is inversely complimentary to the shape of theleading apex 118 and asecond edge 126 that allows the V shapedplow 105 to more easily cut through accumulated snow as it is pushed by the user. It is anticipated that thesecond edge 126 of thedeflector 124 can utilize many shapes, including but not limited to a straight, convex, or concave edge shape, between theupper edge 106 andlower edge 108 of the V shapedplow 105 further enhance the deflecting properties of thedefector 124. As an example,FIG. 2 depicts a convexsecond edge 126 of thedeflector 124. To further aid in the channeling of snow as the user pushes thesnow removal device 100, the outward facingsurface 114 of each of thesections plow 105 can utilize aconcave shape 120 between theupper edge 106 andlower edge 108. This aids in channeling snow forward and out the sides of the of the V shapedplow 105 rather than up and over the top of the V shapedplow 105. - Looking to
FIGS. 3 and 4 , provided are perspective and exploded views, respectively, of the V shapedplow 105 of thesnow removal device 100 of the present invention. Here is it easier to see the components that make up the V shapedplow 105 of thesnow removal device 100 of the present invention. Specifically, the firstrigid section 103, secondrigid section 104, andbracket 122 of the preferred embodiment of the V shapedplow 105 are shown. Eachrigid section upper edge 106, alower edge 108, aproximal edge 110, adistal edge 112, an outward facingsurface 114, and an inward facingsurface 116. Eachsection proximal edge 110 to form theleading apex 118 of the resulting V shapedplow 105. As discussed above, the angle of the connection between the twosections plow 105. Thebracket 122 is connected to one ormore sections surface 116 of the V shapedplow 105. The vertical position of thebracket 122 is modified depending on the embodiment of thesnow removal device 100 configuration desired. Also depicted inFIGS. 3 and 4 is aconcave shape 120 for the outward facingsurface 114 between the upper andlower edge section surface 116 will take on an inversely angled convex shape compared to the outward facingsurface 114 unless additional material is utilized along the inward facingsurface 116 to alter its shape. Although an outward facingconcave shape 120 is described above, it should be appreciated by one skilled in the art that any desired outward or inward facing surface shape can be utilized without departing from the scope of the invention. - The acuteness of the
concave shape 120 of the outward facingsurface 114 may increase along a gradient as it gets closer to theproximal edge 110 or thedistal edge 112 of eachsection upper edge 106 or thelower edge 108 of eachsection concave shape 120 of the outward facingsurface 114 of eachsection V shape plow 105 creates a curled end (SeeFIG. 7 ) that can further enhance the snow channeling ability of the V shapedplow 105 of thesnow removal device 100 of the present invention. For example, if theconcave shape 120 creates an exaggerated lip at thelower edge 108 of the V shapedplow 105, it would enhance the ability of the V shapedplow 105 to lift and channel accumulated snow up the plow's 105 outward facingsurface 114. This is advantageous since snow will not build up along thelower edge 108, due to friction between the V shapedplow 105 and the pathway to be cleared and/or between particles of snow as they are moved by thesnow removal device 100 of the present invention, which would increase the resistance felt by the user. Conversely, if an exaggeratedconcave shape 120 ends along theupper edge 106, it will aid in keeping snow from moving up and over the top of the V shapedplow 105, especially as the snow is moved from the center of theplow 105 to the distal ends. - Referring to
FIGS. 5 and 6 , provided are perspective and exploded views of an alternative embodiment of the V shapedplow 105 of thesnow removal device 100 of the present invention. The embodiment depicted inFIGS. 5 and 6 utilizes adeflector 124 integrally attached to theleading apex 118 of the V shapedplow 105 of thesnow removal device 100 of the present invention.FIG. 6 particularly points out the inversely complimentary shape of thefirst edge 125 of thedeflector 124 compared to the shape of theleading apex 118. If aconcave shape 120 is utilized for the outward facingsurface 114 of each of thesections plow 105, the resultingleading apex 118 will also be concave in shape. Accordingly, thefirst edge 125 of thedeflector 124 must inversely match the shape of theleading apex 118 in order to properly integrate with the apex 118. Thesecond edge 126 of thedeflector 124 depicted inFIGS. 5 and 6 shows a straight edge between the upper andlower edge second edge 126 of thedeflector 124 of thesnow removal device 100 without departing from the scope of the present invention. Additionally, it should be appreciated by one skilled in the art that any overall shape for thedeflector 124 may be utilized without departing form the scope of the present invention. - Referring now to
FIG. 7 , shown is a perspective view of another alternative embodiment of the V shapedplow 105 of thesnow removal device 100 of the present invention. As shown, thebracket 122, in this embodiment, is attached toward the distal ends of the inward facingsurface 116 of bothsections plow 105 of thesnow removal device 100 of the present invention. However, it should be appreciated by one skilled in the art that the attachment point of thebracket 122 to the V shapedplow 105 may be moved without departing from the scope of the present invention. Additionally, it should be appreciated by one skilled in the art that the shape of thebracket 122 may be modified without departing from the scope of the present invention. - Also illustrated in
FIG. 7 is a gradientconcave shape 120 of the outward facingsurface 114 of eachsection plow 105. The concave shape gradient increases as it gets closer to theupper edge 106 or thelower edge 108 of eachsection plow 105 of thesnow removal device 100 of the present invention. The embodiment illustrated inFIG. 7 provides an exaggerated lip along thelower edge 108 of the V shapedplow 105. As discussed above, the extended lower edge can enhance the ability of the V shapedplow 105 to lift and channel accumulated snow up the plow's 105 outward facingsurface 114. Again, this is advantageous since snow will not build up along thelower edge 108, due to friction between the V shapedplow 105 and the pathway to be cleared and/or between particles of snow as they are moved by theplow 105, which would increase the resistance felt by the user. Conversely, if an extendedconcave shape 120 ends along theupper edge 106, it will aid in keeping snow from moving up and over the top of the V shapedplow 105, especially as the snow is moved from the center of theplow 105 to the distal ends. - Although various representative embodiments of this invention have been described above with a certain degree of particularity, those skilled in the art could make numerous alterations to the disclosed embodiments without departing from the spirit or scope of the inventive subject matter set forth in the specification and claims.
