| 20130199061 | SNOW REMOVAL DEVICE - A plow device includes a plow member and a handle that is pivotally connected to the plow member. The plow member is generally U-shaped, and retains snow or other loose material as the U-shaped member slides over a ground surface. | 08-08-2013 |
| 20150330043 | Snow Removal Device and Method - A snow removal device comprising a pad or mat assembly having a bottom surface and a top surface and a plurality of flexible vertical blades having alternating, variable lengths that extend from both the bottom surface and top surface. The varying lengths of blades help prevent the blades positioned at the bottom surface of the pad assembly from freezing to the ground when the device is in use. Reinforced ergonomic handles with flexible, gripped covers are incorporated into the pad assembly for lifting and moving the device from one location to another and for inclining the surface so that accumulated snow falls off. At least two vertically extending poles with flags are positioned diagonally opposite one another at corners of the device so that a user can determine the precise location of the device after it is submerged in snow. | 11-19-2015 |
