Patent ID: 8549971

Claim:
A portable saw system comprising: a base including a first locking member and a second locking member; a support arm system defining a cutting axis; a power tool supported by the support arm system, the power tool having a saw blade configured to move along the cutting axis; and a fence with a first side defining a first guide and a second side opposite to the first side and defining a second guide, wherein the fence includes a cutout structure having a concave interior wall, wherein the concave interior wall defines a cutout recess, wherein the fence is (i) configured to couple with the first locking member such that the cutout recess is aligned with the cutting axis and (ii) configured to couple with the second locking member such that the second guide is parallel with the cutting axis, wherein the first guide includes (i) a left guide part defining a left top edge and a left bottom edge, and (ii) a right guide part defining a right top edge and a right bottom edge, wherein, when the fence is coupled to the first locking member, (i) the left bottom edge and the right bottom edge are juxtaposed to the base, and (ii) the left top edge and the right top edge are spaced apart from the base, wherein the concave interior wall defines (i) a left wall edge extending from the left top edge to the left bottom edge, (ii) a right wall edge extending from the right top edge to the right bottom edge, and (iii) an intermediate wall portion extending from the left wall edge to the right wall edge, wherein the left wall edge and the right wall edge collectively define an access opening leading to the cutout recess, and wherein when the fence is coupled to the first locking member movement of the saw blade along the cutting axis causes the saw blade to advance through the access opening and into the cutout recess.
