Patent ID: 7798041

Claim:
A power tool comprising: a base supportable on a surface to support the power tool on the surface; a table supported by the base for pivoting movement about an axis; a detent assembly between the base and the table and operable to coarsely adjust an angular position of the table relative to the base and secure the table relative to the base in at least one selected angular position, the detent assembly including a detent projection supported on one of the base and the table, a lever coupled to the detent projection, and a plurality of detent recesses defined by the other of the base and the table, the projection being engageable in a first of the recesses to secure the table relative to the base in the selected angular position, the lever being operable to disengage the projection from a recess; a fine adjustment assembly between the base and the table and operable to finely adjust an angular position of the table relative to the base, the fine adjustment assembly including a rotating member supported by one of the base and the table, an engagement surface provided by the other of the base and the table, the rotating member being selectively engageable with and rotatable along the engagement surface to finely adjust the angular position of the table relative to the base, the rotating member being adjustable between an engaged position, in which the rotating member is drivingly engaged with the engagement surface, and a disengaged position, in which the rotating member is drivingly disengaged from the engagement surface, a biasing member operable to bias the rotating member toward the disengaged position, and a detent override assembly which, in response to the rotating member engaging the engagement surface, disengages the detent projection from the first detent recess, holds the detent projection out of engagement with the first detent recess, and prevents the detent projection from engaging a second of the plurality of detent recesses, the detent override assembly including a ramp moveable in response to movement of the rotating member from the disengaged position to the engaged position, a portion of the lever sliding on the ramp to disengage the detent projection from the detent recess, wherein the angular position of the table relative to the base is coarsely adjustable using the detent assembly when the rotating member is disengaged from the engagement surface, and wherein the detent override assembly defines a notch, a portion of the lever being engageable with the notch to maintain the rotating member engaged with the engagement surface against the bias of the biasing member.
