Blade guard.

摘要

A guard (10) for teeth (15) on a cutting blade (12) comprising a guard portion (18) having a side part (19) adapted to lay along one side of the teeth (15) and a projecting part (20) adapted to project past the points of the teeth (15), an anchor portion (22) adapted to be fixed to the blade (12) at a position spaced from the teeth, and a hinge portion (24) of resiliently flexible polymeric material joining the guard and anchor portions. The hinge portion (24) affords movement of the guard portion (18) relative to the anchor portion (22) from a normal protecting position along and projecting past the teeth (15), to a cut position spaced from the teeth (15) so that the teeth (15) can be used to cut material, while biasing the guard portion (18) to its normal protecting position.
