Abstract:
A removable power tool guard configured to cover an area proximate a spindle assembly of a power tool between a spindle assembly and a user of the tool, the guard further being configured to be securely mounted to a semi-elastic lower bearing housing supporting the spindle assembly of the power tool, wherein the guard, when mounted to the lower bearing housing, and when in use during operation of the tool, must remain in place even under conditions of flying debris, such as under conditions of an exploding, rotating abrasive grinder wheel mounted on the lower bearing housing of the tool, the guard comprising:a guard hood configured to cover an area proximate the spindle assembly between the spindle assembly and the user of the tool; a clamp ring mechanically coupled to the guard hood; the clamp ring depending from the guard hood; the clamp ring having an inner circumferential portion; the clamp ring being configured so that the inner circumferential portion at least partially surrounds, and can be secured tightly around, at least a portion of the semi-elastic lower bearing housing; the clamp ring being configured so that at least a portion of the semi-elastic lower bearing housing can pass essentially concentrically through the clamp ring; the inner circumferential portion of the clamp ring defining at least a partially-knurled surface; and whereby, when securely tightened around the semi-elastic lower bearing housing, the at least partially-knurled surface of the clamp ring inner circumferential portion compresses into the semi-elastic lower bearing housing to securely mount the guard member to the tool.
