Patent ID: 8460070

Claim:
An angle grinder with a tool rotatably drivable about an axis, a guard device comprising a guard fixedly connectable to the hand-held power tool, said guard extending over a first angular range around a guard axis which is arranged to substantially coincide with the axis of rotation of the tool so as to cover at least a part of the tool to protect a user; a protective cover extendable over a second angular range around said guard axis and rotatable relative to said guard about said guard axis, so that in one position said protective cover is located within said guard substantially in a same angular region, and when rotated relative to the guard, said protective cover is located in another, circumferentially neighboring angular region so as to cover jointly with said guard a greater angular range than said first angular range; and guide means for guiding said protective cover during its rotation relative to said guard and including respective guiding elements on said protective cover and on said guard that interact with one another during the rotation of the protective cover relative to said guard to guide the protective cover; wherein said protective cover is mounted rotatably on said guard so that if the tool breaks during operation and if a piece from the broken tool strikes said protective cover, said protective cover rotates relative said guard; and wherein said protective cover and said guard device extend around an entire angular range of the tool of 360° when in a protective position.
