ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The instant invention relates to that field of devices that are utilized for the leveling and squaring of door frames.
2. Prior Art
The accompanying Informational Art Statement delineates art that however does not anticipate the instant invention.
A SUMMARY OF THE INVENTION
1. A Brief Description of the Invention
The instant invention is rectangularly shaped and is amenable to being fitted to any conventional door frame unit. Each half of the invention is able to be adjusted sidewise by virtue of the presence of an adjustable slideable scale bar in a top side thereof and a corresponding adjustable, slideable bar located within the bottom side thereof. A pair of adjustable vertically aligned locking members affixed to the top side permit a tightening of the invention to a top side of a wooden door frame unit. A pair of adjustable horizontally aligned locking members affixed to the bottom side thereof, permit a tightening of the invention to lateral sides of a door frame. A plurality of adjustable hinge units affixed to the right lateral side of the invention permit affixation of the invention to hingeholders affixed to a door frame unit in the same manner that hinges on a door would be affixed to hingeholders of a door frame unit. The right lateral side of the invention is further characterized by the presence of a pair of horizontally aligned bubble leveling components. There is a plurality of laterally positioned spaces within each lateral side of the invention serving to facilitate the nailing of the door frame unit to shim pieces placed between the door frame unit and the building frame encasing the door frame unit and in turn to the building frame. Also, there are two horizontally aligned stabilizing members that are horizontally adjustable that hold the instant invention in place within a door frame unit while it is being locked fast to the door frame unit. Finally, affixed along the exterior edging of an upper portion of the right lateral side of the invention and continuously along the exterior edging of the half of the top side connected to the uppermost portion of the right lateral side thereof, there is a magnetized metallic strip. The magnetic strip facilitates stabilized affixation of the invention to a metallic door frame unit to facilitate the hanging of metal doors.
Utilization of the invention permits one to readily and strategically place shim pieces between a wooden door frame unit and building frame serving to encase it, so that prior to the hanging of a door, an installed door frame unit would be virtually perfectly square with respect to the lie of the building frame serving to encase it thereby permitting quick and ready door hanging so as to render the door, without the need for perhaps any planing or cutting thereof be also virtually perfectly square with respect to the lie of such building framing. Utilization of the invention permits one to moreover also appropriately adjust a metallic door frame unit so as to be perfectly square as respects building framing circumscribing the unit so that a metal door would then be likewise quickly readily and dependably hung by affixation thereto.
2. Objects of the Invention
As matters currently stand, the properly square hanging of a door and door frame combination within the confines of a building frame opening available for such purposes is a relatively formidable task. For the most part, such hanging requires the skills of highly qualified carpenters. The inherent difficulty in accomplishing the same lies in the fact that far too often, the building frame opening itself, would not be perfectly square in relationship to the lines of a given door and frame sought to be hung therein. Consequently, two persons, one of whom would be an experienced carpenter are required to manipulate a level, hold the door frame, shim it and nail it into place within the building frame unit so as to render the door frame unit as perfectly square as possible with respect to the lie of the building frame unit to which it would be attached. Such an undertaking to be done correctly takes a goodly amount of time and effort. It was in response to the fact of such a dilemma that the instant invention was conceived and then created. The instant invention enables just one person without necessarily the expertise of a highly skilled carpenter to easily affix a door frame unit to an encasing building frame quickly, readily and invariably dependably in such a manner that a hung door will be virtually perfectly square with respect to the lie of the perimeter of the opening within the building frame unit to which the door frame unit would be affixed. Moreover, due to the feature of side to side adjustability of the invention, doors of many sizes can be hung by just one person utilizing the instant invention in the manner outlined above. Also, as noted above, the invention is amenable to facilitating the hanging of both wooden and metallic doors.
Respectfully submitted, for the reasons cited above, the instant invention is not only new and unique but unquestionably useful as well.
