| Abstract: |
An ice/snow scraping system includes a ribbed grip handle, shielded from ice, snow and moisture by a sleeve which is open at the rear, and a removeable scraper head. The head includes a downward biased portion incorporating the scraper's edge to provide optimum scraping angle while safely spacing the handle from the ice, strengthening ribs positioned for resistance to torque and thrust forces, and a strip of raised serrations for abraiding the ice. Mating abutments on the head and handle transfer torque and thrust back to the handle. Pin interlock resists accidental disassembly. The scraper head abutment is shaped to protect the sleeve-to-handle seal from run off when the system is hung up to a mounting hole provided in the biased portion.

First Claim:
Show all 6 claims |
What is claimed is:
1. An system capable of scraping ice or snow which comprises, in combination;
- a handle having a front end, a back end and a virtual centerline,
- a first abutment on the front end of the handle,
- a keyhole located in the forward face of the abutment for receiving a key post,
- a scraper head having a front end, a top surface, a bottom surface, a back end and a virtual centerline,
- a key post on the back end of the head, extending along its centerline, shaped for close fit to said keyhole,
- a second abutment located forward on the key post for mating with the first abutment when the post is inserted into the keyhole,
- a rigid straight edge for scraping, located at the front of the scraper head and extending substantially perpendicularly with respect to the head's centerline,
- a forward portion of the head being biased so that a virtual plane that includes the straight edge forms an acute angle with the centerline,
- a strip of raised serrations located on the top of the scraper on the biased portion for abrading, and
- a flexible sleeve which encloses the handle, sealingly formed around the handle behind the first abutment and having an opening near the back of the handle and having sufficient space about said enclosed handle to permit hand access to the handle for holding it from within the sleeve,
- said first abutment including a V-shaped portion and being positioned with the apex of the V located on the centerline of the handle, and the second abutment being v-shaped.
