ABSTRACT:
A tool for scraping ice, frost, and snow from a vehicle's windscreen and windows with very little time and effort comprising of a center handle (28) which acts as a fulcrum, and two lever arms (30R and 30L) which act as levers, which incurve and join each other to form the forearm rest (32) at the rear extermity of the unit. The forearm rest sits on the user's forearm when using the device in a horizontal scraping direction. The levers form contoured arms (26R and 26L) towards the front of the unit, ahead of the center handle. These contoured arms hold the scraping blade (22) and the scraping teeth (20), which are supported by the reinforcing plate (24) between the contoured arms. The device facilitates the act of cleaning winter elements off a windscreen or window through the use of leverage provided by the user's hand acting as a fulcrum and one's forearm supplying the leverage necessary to create substantial downward pressure on the surface to be scraped without the extensive reach needed with conventional scrapers.
