Patent ID: 8359961

Claim:
A portable cutting-guidance apparatus adapted to be used with a portable power cutting-tool that has a cutting implement which cuts an object at a variably selected angle, including: a portable positioning means adapted, in use, to be positioned motionless relative to an object to be cut by a portable power cutting-tool; and a linear cutting-guide adapted to enable the portable power cutting-tool to travel on and along the cutting-guide in a straight line; the linear cutting-guide being pivotally connected to the positioning means about a pivot point and its associated pivot axis by a variable-angle mechanism that is adapted to adjustably fasten the cutting-guide to the positioning means at a variably selected angle relative to one another, such that, in use, the portable power cutting-tool is able to travel on and along the cutting-guide to cut the object in a straight line at the variably selected angle; wherein the positioning means includes an abutment surface adapted, in use, to abut the object so as to position the positioning means motionless relative to the object, and wherein the positioning means is adapted, in use, to be positioned and held against the object by manual force of the user, the manual force including force with which the user pushes the portable power cutting-tool forwards along the cutting-guide to cut the object, wherein the portable cutting-tool is removably attachable to the linear cutting guide such that the cutting-tool is able to reciprocate back and forth along the cutting guide while attached thereto, wherein the cutting-guide is provided with a cutting-tool support adapted to travel along the cutting-guide, and adapted to have the portable cutting-tool attached thereto such that, in use, when the cutting-tool is attached to the linear saw guide, the user is able to lift and operate with one hand the entire portable cutting-guidance apparatus as one integral unit with the cutting-tool attached, wherein the linear cutting-guide has a leading edge which, in use is closest to the cutting implement, wherein the pivot point is distanced from the leading edge of the cutting-guide such that the entire leading edge is able to pivot around and about the pivot point, wherein the pivot point and the cutting implement are located on the same side of the linear cutting guide with no part of the linear cutting guide coming between the cutting implement and the pivot point and its associated pivot axis, and wherein, when the portable cutting-tool is attached to the cutting-tool support, the cutting implement is distanced between the pivot point and the leading edge of the cutting-guide such that when the positioning means is held against the object by the manual force of the user, it is possible to adjust the selected angle of the cut without significantly altering the point at which the object is cut.
