Door jalmb jigs

Abstract

The current invention comprises a set of Door Jamb Jigs designed to enable the user to temporarily hold a carpenters level, a carpenters square, and a door jamb firmly within the rough opening of a framed wall so that the door jamb can be permanently nailed in place pre-squared, pre-leveled, and pre-plumb. The current invention utilizes universally designed Jigs that enable users to utilize their own conventional carpenters square and carpenters level combined with the Door Jamb Jigs to practice a new method of installing pre-hung interior doors much easer, faster and more accurately compared to the conventional practice of holding tools by hand. The current invention solves problems during the Pre-hung door jamb installation process. #1 The invention enables the user to temporarily attach both a 90 degree carpenters square and a carpenters level to the door jamb so when the door panel is reattached to the jamb the clearance between the door panel and the door jamb is equal and parallel all around. #2 By using this method of pre-squaring the head of the jamb in relation to the hinge side of the jamb, and pre-straightening the hinge side of the jamb with the carpenters level attached to the jamb pre-plumb the user can accurately determine how much shimming is required to allow for twisted framing lumber. Thus eliminating jamb torque, and bound hinges. #3 By adjusting the standoff screws the jamb be positioned flush with the finished wall.

I claim: 
     
         1 . An accessory device of mechanical means and structural slot for urging integration of a 90 degree carpenters square and a carpenters level contiguously sandwiching affixing and binding said combination of tools temporarily to a door jamb comprising an L shaped jig body with a slot to accommodate a proposed carpenters framing square and a protrusion within said jig body that can bind a door jamb between said mechanical means said jig body said level and said square simultaneously.
