Patent
CA 2268568
A windshield scraper, for removing frost or ice from glass surfaces of motor vehicles, has a blade attached to an elongate main handle, plus an auxiliary handle swivellably connected to the main handle. The user holds the main handle with one hand, with the blade at a desired angle against the surface being scraped, while with the other hand holding the auxiliary handle at a desired angle relative to the main handle. The user applies longitudinal force to both the main handle and the auxiliary handle. The force applied to the main handle acts primarily to move the blade across the scraped surface. The force applied to the auxiliary handle acts primarily to augment the normal force against the surface, keeping the blade in effective contact with the surface as it is moved across the surface.
