Abstract
A hand-held power saw (10) having a housing (112) which includes a blade storage chamber (124) and a retaining member (130) for holding at least one spare saw blade (26) within the storage chamber. In one embodiment the retaining member comprises a rubber component having a pair of arms (136). Each arm has a groove (138) formed therein which holds a ball bearing (140). The ball bearings are biased into contact with one another once the retaining member is assembled into a housing portion of the tool within the storage chamber. When a spare saw blade is inserted into the storage chamber a portion thereof is urged between the ball bearings. The resiliency of the rubber arms causes the ball bearings to grasp the spare saw blade and retain it within the storage chamber. The opposite end of the blade engages a foam-like member (150) held within a recess (124c) at the opposite end of the storage chamber which prevents the blade from rattling within the chamber. In alternative embodiments a pivotably mounted retaining member (30) is disclosed which operates in cooperation with an independent clip (32) to retain a spare saw blade in the storage compartment. The various embodiments enable a…
