Patent ID: 7631587

Claim:
A locking system for use with a power tool, comprising: a turntable; a power tool support pivotably mounted to said turntable, said power tool support including (i) a wall defining a first arcuate opening therein, and (ii) a first bearing plate defining a second arcuate opening therein, said first bearing plate being mounted in relation to said wall so that said second arcuate opening is aligned with said first arcuate opening; an actuator movably mounted in relation to said turntable; a linkage having a first end portion coupled to said actuator and a second end portion extending through both said first arcuate opening and said second arcuate opening, said linkage including a first brake pad supported on said second end portion, wherein (i) movement of said actuator from a first location to a second location causes movement of said linkage from a first position to a second position, and (ii) movement of said actuator from said second location to said first location causes movement of said linkage from said second position to said first position, wherein movement of said linkage from said first position to said second position causes said first brake pad to be moved toward said first bearing plate so that pivoting of said power tool support in relation to said turntable is inhibited, and wherein movement of said linkage from said second position to said first position causes said first brake pad to be moved away from said first bearing plate so that pivoting of said power tool support in relation to said turntable is enabled, wherein said power tool support further includes a second bearing plate having a third arcuate opening defined therein, wherein said second bearing plate is mounted in relation to said first bearing plate so that said third arcuate opening is aligned with said second arcuate opening, wherein said linkage further extends through said third arcuate opening, and wherein said linkage further includes a second brake pad supported on said second end portion of said linkage and interposed between said first bearing plate and said second bearing plate.
