Abstract
A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.
Claims8
A miter saw comprising:
- a base assembly;
- a saw unit pivotably coupled to the base assembly, the saw unit including a saw blade and a lower blade guard covering a lower portion of the saw blade;
- and
- a linkage operable to raise the lower blade guard in a first rotational direction to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly, the linkage having a rear end pivotably coupled to the base assembly about a first pivot axis and an opposite front end, wherein the length of the linkage between the front and rear ends is fixed, wherein the linkage includes a slot, having a front end and a rear end, proximate the front end of the linkage in which a protrusion of the lower blade guard is received, wherein the lower blade guard is inhibited from moving in the first rotational direction when the lower blade guard is in a first raised position by engagement between the rear end of the slot and the protrusion, and wherein the engagement between the rear end of the slot and the protrusion of the lower blade guard also inhibits movement of the lower blade guard in a second rotational direction opposite the first rotational direction when the lower blade guard is in a second raised position to facilitate changing the saw blade.
