Abstract
A molded ice scraper one piece body has independently flexible finger portions terminating in aligned scraping edges that are joined by webs a few thousandths of an inch thick. A continuous, but breakable, blade is thereby formed that will clean a streak-free swath on a windshield or similar surface. The slots separating the fingers are curved where they meet the scraper intermediate section, to eliminate stress concentration. The fingers have forward facing ice deflecting surfaces at an obtuse angle to the surface to be cleaned, extending from the scraper edge, and front facing ice chipping surfaces extending vertically upwardly from an intersection with the ice deflecting surfaces that is spaced back from the scraper edge.
Claims10
A hand-held scraper for removing ice from a smooth surface, said scraper comprising a one piece body defining:
- a handle section extending from said handle section, and a blade region comprising:
- a plurality of resilient, independently flexible, scraping fingers, each said finger extending from said intermediate section and terminating in a front scraping edge, and
- a plurality of thin web members, each said web member being thin enough not to interfere with the individual flexibility of said scraping fingers, and extending from a finger to an adjacent finger, and having a thin front edge aligned with said scraping edges of said web members, and the scraping edges of said fingers thereby forming a continuous scraper blade edge.
A hand-held scraper for removing ice from a smooth surface, said scraper comprising a molded one piece body defining:
- a handle section,
- an intermediate section extending from said handle section, and
- a blade region comprising:
- a plurality of resilient, independently flexible, scraping fingers,
- each said finger extending from said intermediate section and terminating in a front scraping edge aligned with the front scraping edges of the other fingers,
- each said finger having lateral edges that converge inwardly upwardly, and that converge inwardly back from said scraper edge to facilitate flexure of said fingers, and
- a plurality of breakable web members, approximately a few thousandths of an inch thick,
- each said web member extending from a finger to an adjacent finger and having a front edge aligned with said finger scraping edges, thereby forming a continual scraper blade edge.
A hand-held scraper for removing ice from a smooth surface, said scraper comprising a one piece body defining:
- a handle section,
- an intermediate section extending from said handle section, and a blade region comprising:
- a plurality of resilient, independently flexible, scraping fingers, each said finger extending from said intermediate section and terminating in a front scraping edge, each said finger having lateral edges that converge inwardly back from said scraping edge, and
- a plurality of web members, each said web member extending from a finger to an adjacent finger and having a front edge aligned with said scraping edges of said adjacent fingers, the front edges of said web members and the scraping edges of said fingers thereby forming a continuous scraper blade edge.
A hand-held scraper for removing ice from a smooth surface, said scraper comprising a one piece body defining:
- a handle section,
- an intermediate section extending from said handle section, and a blade region comprising:
- a plurality of resilient, independently flexible, scraping fingers, each said finger extending from said intermediate section and terminating in a front scraping edge, each said scraping finger having lateral edges that converge inwardly upwardly, companion ones of said scraping finger scraping edges being adjacent, and
- a plurality of web members, each said web member extending from a finger to an adjacent finger and having a front edge aligned with said scraping edges of said adjacent fingers, the front edges of said web members and the scraping edges of said fingers thereby forming a continuous scraper blade edge.
