Abstract
Abstract An ice-scraper used to scrape off ice and frost formed on the outer convex glass surface of a vehicle windshield. This ice-scraper consists of a one-piece triangular shape body made of precast flexible and resilient plastic material. The base edge of said body is bevelled to form a scraping edge. The body has a slit extending parallel to this base edge and terminating short of the side edges of the body to define a flexible blade portion adapted to contact a convex glass surface over substantially the entire length of the scraping edge.

Claim 1
Independent Claim
201 words
An ice-scraper for the outer convex surface of a vehicle window, comprising a body of flat triangular shape and made of a cast one-piece flexible and resilient plastic material, said body having a straight base edge, an opposite apex portion and converging side edges, said straight base edge bevelled to form a scraping edge, said body having a slit parallel to said base edge and located intermediate said base edge and said apex portion, said slit terminating short of and at a generally equal distance from the respective side edges, the part of said body lying between said slit and said base edge forming a blade portion, and the part of said body extending from said slit towards and including said apex portion forming a shank portion, said base portion being integrally connected to said shank portion solely beyond the ends of said slit, whereby said blade portion can flex in a direction parallel to said base edge when applied against a convex window surface by pressure applied on the ends of said blade portion through said shank portion, and a separate handle rigidly secured to said shank portion, extending away from said body and generally perpendicular to said base edge.
