Abstract
Abstract An ice and snow scraper adapted to be held in the hand of a user is disclosed. The scraper comprises a one-piece body having a hand-fitting handle section, a blade section, and an intermediate section. The blade section comprises a scraping surface and an oblique ice-deflecting surface. The intermediate section is curved so as to displace the blade section below the plane of the handle section. This scraper shape facilitates the application of force longitudinally of a surface to be scraped with the hand of the user remaining spaced from that surface while ice is deflected substantially away from the hand of the user and the blade is oriented at the optimum scraping angle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
261 words
A scraper for removing ice from a surface to be scraped, said scraper comprising a body having top and bottom surfaces, said body defining: a scraping blade at one end thereof comprising a deflecting surface extending obliquely from said top surface toward said bottom surface, and a scraping edge; a handle section remote from said one end located at the extremity of the body of said scraper, said handle section having a longitudinal axis; and an intermediate section curved to define a convex portion of said top surface extending between said blade and said handle section, projecting below said axis, and being substantially free of obstructions to the removal of ice therefrom, and a concave portion of said bottom surface extending between said blade and handle section below said axis; said scraper being operable during scraping to permit force to be applied longitudinally of a surface to be scraped with the hand of the user, when gripping said handle section, remaining substantially spaced from the surface to be scraped, with ice thrown by the deflecting action of said deflecting surface and said convex portion of said top surface being substantially deflected away from said hand of said user, and with said deflecting surface being oblique relative to said surface to be scraped, said handle section, on lateral edges thereof, providing a generally wedge shaped handle configuration operable to progressively resist pushing force imposed on said handle section and directed toward said scraping blade; and said handle section being grippable on the underside thereof adjacent a free end of said handle section.
Claim 2
Dependent Claim
261 words
A scraper for removing ice from a surface to be scraped, said scraper comprising a body having top and bottom surfaces, said body defining: a scraping blade at one end thereof comprising a deflecting surface extending obliquely from said top surface toward said bottom surface, and a scraping edge; a handle section remote from said one end located at the extremity of the body of said scraper, said handle section having a longitudinal axis; and an intermediate section curved to define a convex portion of said top surface extending between said blade and said handle section, projecting below said axis, and being substantially free of obstructions to the removal of ice therefrom, and a concave portion of said bottom surface extending between said blade and handle section below said axis; said scraper being operable during scraping to permit force to be applied longitudinally of a surface to be scraped with the hand of the user, when gripping said handle section, remaining substantially spaced from the surface to be scraped, with ice thrown by the deflecting action of said deflecting surface and said convex portion of said top surface being substantially deflected away from said hand of said user, and with said deflecting surface being oblique relative to said surface to be scraped, said handle section, on lateral edges thereof, providing a generally wedge shaped handle configuration operable to progressively resist pushing force imposed on said handle section and directed toward said scraping blade; and said handle section being grippable on the underside thereof adjacent a free end of said handle section.
Claim 3
Dependent Claim
53 words
The scraper as set forth in claim 1 wherein said convex portion of said top surface is progressively more steeply inclined away from said longitudinal axis of said handle section and is operable to provide the greatest resistance to movement of ice over the top surface of said scraper adjacent said scraping edge.
