Patent ID: 8523640

Claim:
A guard hood torsion preventer for a handheld power tool, comprising: a guard hood mounted on the handheld power tool in a manner so as to partially cover a tool of the handheld power tool, the guard hood defining a first longitudinal axis; and at least one torsion-prevention unit defining a second longitudinal axis about which the torsion-prevention unit is rotatably supported, wherein the at least one torsion-prevention unit is configured to rotate about the second longitudinal axis and is formed at least partly by a form-locking unit, and wherein rotation of the at least one torsion-prevention unit about the second longitudinal axis causes a portion of the at least one torsion-prevention unit configured to urge against an adjacent portion of the guard hood to rotate the guard hood about the first longitudinal axis, the portion of the at least one torsion-prevention unit configured to remain in continuous engagement with the adjacent portion of the guard hood from any starting position and for any positive or negative rotation of the at least one torsion-prevention unit about the second longitudinal axis, the interaction of the portion of the at least one torsion-prevention unit and the adjacent portion of the guard hood resisting rotation of the guard hood when the guard hood is acted upon by an external force.
