Battery powered circular saw
First Claim
1. A circular saw comprising:
- a housing having a motor housing portion and a battery connection portion, the battery connection portion extending rearwardly from the motor housing portion;
a circular saw blade coupled to the housing and rotatable about a rotational axis;
a handle coupled to the housing, the handle being disposed perpendicular to the rotational axis and having first and second ends, the first end of the handle being coupled to the motor housing portion, the second end of the handle being disposed rearwardly and below the first end of the handle and being coupled to the battery connection portion;
a battery pack that is removably coupled to the battery connection portion of the housing, the battery pack being moveable in first and second directions that are generally parallel to the circular saw blade;
a shoe assembly coupled to the housing, the shoe assembly having a shoe and an adjustment mechanism for selectively adjusting a position of the shoe relative to the housing, the adjustment mechanism including a depth-of cut member that is coupled to the shoe and a clamp that is coupled to the housing forwardly of the second end of the handle, the clamp being selectively operable for drawing the depth-of-cut member against the housing to thereby inhibit movement of the depth-of-cut member relative to the housing.

Abstract
A battery powered circular saw includes a rechargeable battery removably attached to the housing and an adjustable shoe pivotally attached to a guard assembly for controlling a depth of cut. A locking mechanism for preventing relative movement between the adjustable shoe and the housing includes a depth of cut strap disposed adjacent a first sidewall of the housing. A lever is disposed adjacent a second sidewall of the housing. A tightening element interconnects the depth of cut strap and the lever. The battery powered circular saw additionally includes a handle extending from the housing. The handle is disposed substantially parallel to a direction of cut and oriented horizontally above the housing. The rechargeable battery pack includes a pair of laterally spaced apart guide rails which cooperate with the pair of longitudinally extending grooves to permit sliding movement of the rechargeable battery pack in a direction parallel to the direction of cut.

29. A circular saw comprising:
-
a housing; a guard coupled to the housing; a circular saw blade associated with the housing and laterally positioned within the guard, the circular saw blade being rotatable about a rotational axis; a handle with a generally V-shaped portion coupled to the housing, the generally V-shaped portion being disposed generally transverse to the rotational axis and having a first end, a second end that is positioned rearward of the first end, an apex, which is disposed above the housing between the first and second ends; a battery pack fixedly but releasably engaged to the housing; a pair of grooves formed on one of the battery pack and the housing; a pair of rails formed on the other one of the battery pack and the housing, the rails being configured to cooperate with the grooves to align the battery pack to the housing such that a center of the battery pack is laterally aligned to a center of the generally V-shaped portion; a shoe; and an adjustment mechanism having a first bracket, a depth-of-cut member and a clamp, the first bracket being fixedly coupled to the shoe, the depth-of-cut member being pivotally coupled to the first bracket and having an arcuate groove formed therein, the clamp including a bolt and a threaded member, the bolt having a non-circular portion that is disposed in the arcuate groove of the depth-of-cut member, the bolt extending through a boss formed in the housing, the threaded member being threadably engaged to the bolt and being configured to translate the bolt within the boss to selectively secure the depth-of-cut member to the housing, the bolt being disposed between the rotational axis and an aft end of the battery pack when the battery pack is fixedly but releasably engaged to the housing, the threaded member being disposed on a side of the housing opposite the circular saw blade. - View Dependent Claims (30, 31, 32, 33)
