Circular saw with improved corner cutting
First Claim
1. A circular saw capable of cutting a workpiece at a generally right-angled corner formed between the workpiece and a structure, the circular saw comprising:
- a saw blade assembly including a motor on a rear side thereof and a saw blade on a front side thereof, the saw blade having a center plane therethrough and being adapted so as to be rotated by the motor;
a generally rectangular base plate having a front edge proximal to the saw blade and distal to the motor and a recess provided in the front edge through which the saw blade protrudes below the base plate; and
a plurality of connecting shafts having a common axis extending in parallel to both the center plane of the saw blade and the front edge of the base plate, the connecting shafts attaching the saw blade assembly to the base plate such that the saw blade assembly is tiltable toward the rear side about the common axis of the connecting shafts, thereby causing at least the portion of the saw blade protruding below the base plate to pivot to the front side, wherein when the blade saw assembly is tilted to hold the saw blade at a right angle relative to the base plate, the axis of the connecting shafts is spaced apart from the center plane toward the motor by a predetermined distance.

Abstract
A circular saw (1) cutting a workpiece at a generally right-angled corner formed between the workpiece and a structure is provided. The saw (1) includes a base plate (2) and a saw blade assembly (3) which has a saw blade (5) rotatably attached thereto and is tiltably mounted on the base plate by first and second pins (12,15) aligned with each other and oriented parallel to the saw blade. This arrangement permits the saw blade (5) to be manually tilted in two directions to desired angles with respect to the base plate (2) within a predetermined range. When the saw blade (5) is disposed at 90 degrees relative to the top surface of the base plate (2), the common longitudinal axis (O2) of the first and second pins (12) and (15) is spaced apart from the center plane (L) of the saw blade (5) toward the motor by a predetermined distance (S) as measured along a path orthogonally intersecting the center plane and the axis.
