ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a guide that can be secured to a wall for guiding a concrete cutting saw in cutting a desired straight cut in the wall.
BACKGROUND OF THE INVENTION
A concrete cutting chain saw is heavy and unwieldy and making straight cuts, e.g., to create a window or door opening in a concrete wall, is a difficult task. Such a task often requires a guide system that supports and guides the saw as the cut is being made. Heretofore such guide systems have been complex in both structure and mounting and it is desirable to find a more simple apparatus that can be easily mounted, e.g., to a wall, and still function as a guide that assists an operator in making a straight wall cut.
BRIEF DESCRIPTION OF THE INVENTION
The present invention in a preferred embodiment includes an elongated track member that is secured to a wall to be cut. It is laid alongside the desired cut line. The track member includes protruding hinge cradles spaced sequentially along the track. The saw is provided with a hinge post that is mated to the hinge cradles. With the track member secured to the wall and starting, e.g., at a point just below the top of the cut line, the hinge post of the saw is nested in a cradle of the track member and the saw blade is pivoted inwardly and downwardly along the cut line. When the cutting procedure at that cradle position is completed, the saw is lifted off the cradle and dropped into a lower subsequent cradle and the procedure repeated. The track member and hinge post are cooperatively designed so that the cut can be made at either side of the track.
The invention will be more fully appreciated upon reference to the following detailed description having reference to the accompanying drawings.
