Abstract

A chop saw includes a base assembly and a saw assembly pivotally attached to the base assembly. The base assembly has a workpiece-supporting plane. The saw assembly has a blade and a motor driving the blade. A hinged connection between the base assembly and a saw assembly allows a user to rotate the saw assembly from a position where the plane of the blade extends through the workpiece-supporting plane to a position where the plane of the blade does not extend through the workpiece-supporting plane. In such position, the plane of blade may be substantially parallel to the workpiece-supporting plane.

First claim

What is claimed is:

1. A chop saw comprising:
a base assembly comprising a rotatable table having a workpiece-supporting plane;
a saw assembly pivotally attached to the base assembly, the saw assembly having a blade having a blade plane and a motor driving the blade,
a fence assembly connected to the base assembly,
wherein a trunnion connects the rotatable table and the saw assembly allowing a user to rotate the saw assembly along a horizontal axis not below the workpiece-supporting plane, and allowing the user to rotate the saw assembly from a first position where the blade plane extends through the workpiece-supporting plane to a second position where the blade plane does not extend through the workpiece-supporting plane, wherein the saw assembly is lockable in the second position without requiring removal of a portion of the fence assembly.

2. The chop saw of claim 1 , wherein the trunnion having a side trunnion hinge that allows the saw assembly to be pivoted between the first and second positions.

3. The chop saw of claim 2 , wherein the saw assembly pivots about the side trunnion hinge about the axis, the saw assembly also pivoting about a bevel axis to change a bevel angle of the blade plane relative to the workpiece-supporting plane, the bevel axis being substantially parallel to the horizontal axis.

4. The chop saw of claim 3 , wherein the chop saw is placeable in a package that has a volume of less than 144,837 cubic centimeters and less than 83,861 cubic centimeters if the blade has a diameter of 12 inches and 10 inches, respectively.

5. The chop saw of claim 4 , wherein the package has a volume of at least about 107,250 cubic centimeters and at least 62,154 cubic centimeters if the blade has a diameter of 12 inches and 10 inches, respectively.

6. The chop saw of claim 3 , wherein the saw assembly further comprises a lock assembly for locking the saw assembly in the second position.

7. The chop saw of claim 3 , wherein the saw assembly has a carrying handle with a center line that is substantially co-planar with a center of gravity of the chop saw, when the saw assembly is in the second position and the workpiece-supporting plane is substantially vertical.

8. The chop saw of claim 7 , wherein the base assembly defines a lower plane substantially parallel to the workpiece-supporting plane, the lower plane being substantially vertical when the saw assembly is disposed in the second position, the chop saw being carryable in a first orientation where the lower plane is disposed between the user and the plane including the center line of the carrying handle and the center of gravity.

9. The chop saw of claim 8 , wherein the chop saw is carryable in a second orientation where the plane including the center line of the carrying handle and the center of gravity is disposed between the user and the lower plane.

10. The chop saw of claim 8 , wherein the base assembly further comprises posts that are substantially perpendicular to at least one of the blade plane, the lower plane and the workpiece-supporting plane, the posts allowing the chop saw to remain in an orientation where the lower plane is substantially vertical.
