An ice scraper is designed in such a way as to minimize stress on joints and allows ergonomic use of muscles and joints during ice removal from vehicle windows by handicapped and elderly consumers and prevents carpel tunnel syndrome and other repetitive use injuries in healthy users. A stock and shoulder brace allow for more force delivery to the surface where the removal is occurring, while relieving forces usually generated from wrists and elbows to accomplish the task. In addition the scraper is mounted on a telescoping grooved shaft designed to work under icing conditions. The shaft is coated with a polymer to resist friction under icing conditions which might interfere with the shaft adjustment.
1) An ergonomic ice and snow scraper where the primary force is generated via a stock against the shoulder.
2) The claim in 1 where the scraper is made from a 2 part sliding extendable tube which locks for individual fitting to optimal anatomical application of the device.
3) The claim in 1 where the tube elements each have perpendicular soft durometer layer sheathed polymer handles which allow for directional force adjustment and while being ergonomically fitted to the hand and being comfortable for arthritic users.
4) The claim in 1 where the handles are replaced by acceptor receptacles for amputees.
5) The claim in where the tubes are grooved for low surface-surface contact during icing and snow conditions allowing for easy use without resistance.
6) The claim in 1 where the tube surfaces have a polymer coating to prevent ice and snow adhesion and subsequent undesirable ice and snow induced tube locking.
7) The claim in 1 where the where the adjustable tightening element which fixes the tubes in place is polymer coated to release ice and snow easily.
8) The claims in 1-7 where the polymer used for handles and coatings is silicone based.
9) The claims in 1-7. Where the mechanical elements are coated with a fluropolymer.
10) The claims in 1-9 where the extending tube elements are electropolished metal.
11) The claims in 10 where the tube metal is aluminum.
12) The claim in 10 where the tubes are made from titanium.
13) The claims in 1-9 where the tubes are alloys of aluminum and titanium.
14) The claims in 1-9 where the tubes are carbon fiber based composite.
15) The claims in 1-14 where the tubes are fixed in place by an adjustable clamp.
16) The claims in 1-14 where the tubes are fixed in place with a screw element.
17) The claims in 1-16 where at least 80 percent of the force required for scraping can be delivered by the shoulder.
