ABSTRACT:
An air directing baffle for a random orbit sander. The baffle includes a main body portion forming an annular opening, a pair of neck portions extending approximately circumferentially opposite from one another, and a pair of recessed portions formed in each of the neck portions. The neck portions extend into airflow registration with a plurality of exhaust slots formed in a shroud rotatably disposed at a lower portion of a housing of the sander. The annular opening is adapted to fit over a boss portion protruding from a lower face surface of the housing of the sander to thus permit the baffle to be rotated freely relative to the housing. The recessed portions in each of the neck portions of the baffle inwardly engage with a pair of inwardly protruding shoulder portions formed in an interior area of the shroud. The interengagement of the baffle with the shroud permits the neck portions of the baffle to be maintained in alignment with the exhaust slots in the shroud as the shroud is rotated by a user during operation of the sander. Thus, the baffle is free to rotate relative to the housing but not relative to the shroud itself. The baffle serves to more effectively direct a cooling airflow drawn in by a fan through inlet slots in a top member associated with the housing such that the airflow is more directly exhausted from the interior area of the shroud. The design of the baffle further does not complicate the assembly of the sander 10 or otherwise add significantly to the overall cost of the sander.
