   BACKGROUND OF THE INVENTION 
   A. Field of the Invention 
   This relates to installing a door frame so that is aligned within the space in all planes and also the method for framing the door. 
   B. Prior Art 
   One of the difficulties when framing a door is to ensure that it is true, level and plumb in all directions. This includes being true and plumb in all planes. If the door is not framed correctly initially, it will not close properly when the surrounding structure is complete. 
   The usual method to install a door is to first position a piece of wood on the concrete floor. A piece of lumber is then extended from this floor piece to the doorjamb. Often times there are two or more pieces of wood on the floor. The problem with this arrangement is that if the worker does not measure the distance from the door to the placement point correctly and the pieces are at different distances, even slightly different distances, from the lower edge of the door frame, the door will not install correctly. 
   However, because of incorrect measurements or inconsistent methods of attaching to the floor, this may produce a door frame which does not allow the door to sit in a finished frame properly. 
   The prior art has tried to address the problem of incorrect framing of a door frame and representative examples of the prior art include Ruff, U.S. Pat. No. 5,704,171, Thistlewaite, U.S. Pat. No. 4,048,771 and Meriwether, U.S. Pat. No. 4,304,078. 
   However, in order to truly install a door frame, which is square relative to the entry as well as relative to the supporting structure, this device has been developed. 
   None of the prior art examples address framing the door in all dimensions and all planes. Additionally, the method of installation in the other devices is substantially different than the method of truly aligning the door within the space as contemplated by this device. 
   BRIEF SUMMARY OF THE INVENTION 
   This device consists of two parallel support members, which extend outward and downward from the top of the door jamb to the floor. The two support members are parallel to each other when installed and are attached to the top of the doorframe by slots in the top framing brackets. The two support members are equal in length. The framing brackets are installed on the doorjamb and are identical in shape and size. The top framing members are secured in place to the door jamb by a screw or nail. 
   The two by four extension members are placed within a slot of the framing brackets and extend to the foot brackets, which are secured to the floor with a screw or nail. 
   The extension members are then inserted into the foot brackets. The foot brackets are identical to each other and stops are inserted within the foot brackets to ensure uniform placement of the extension members within the device. Stops are also placed in the two top framing brackets to maintain position of the extension members within the framing members and foot brackets and to prevent slippage. 
   Because of the identical dimensions of the foot brackets, framing brackets and extension members, uniform placement of the door within the frame itself is achieved. 
   Additionally, there is a side member, which is attached to a separate side foot bracket and extends from the side foot bracket to the side of the door. One end of the side member is inserted within a slot in the side foot bracket and uses the existing hinge holes of the door frame to secure the side member to the door frame. 
   The use of the two extension members and the side member together ensures the true fit of the door frame in all planes. 
   Only one side member is necessary for proper installation although more than one can be used. 
   The method of installing a door frame must be kept simple and uniform in order to produce uniform results. This device accomplishes that object with minimal room for human error.

   DETAILED DESCRIPTION OF THE EMBODIMENTS 
   One of the objects of this device is to ensure that a door is framed within the door opening in all planes. This device will accomplish that result with relative ease and with unique simplicity. 
   When this device is used, a door will be frames correctly in all planes. The device can be easily picked up and transported to the next door or the next job site. It will be constructed of durable material such as fiberglass re-enforced plastic (FRP). It is not anticipated that metal will be used because metal is corrosive and heavy. 
   Additionally, fiberglass is probably the preferred material because of its lightweight and durable characteristics in addition to its relatively low cost. 
   This device is comprised of two identically shaped top framing brackets  25 , each of the top framing brackets is attached via a slot or opening in the top framing bracket  25  to the top of a door frame  5 , three foot brackets  20 , which also have a slot or opening for the respective extension member, two extension members  10  and a side support member  8 . 
   The framing brackets  25  are identical as far as shape, configuration and dimension to each other. Likewise, the foot brackets are identical as far as shape, configuration and dimensions. The two extension members  10  are identical in shape and length. The side member  8  may or may not be identical to the extension member  10  but has the same general shape. 
   Both top framing brackets  25  will be installed over the lip  9  on the door frame  5  and both framing brackets  25  have an opening  7  to insert the extension member  10 , which extends from one side of the framing bracket  25  to the foot bracket  20  which has been placed on the ground. 
   Holes  16  are placed in the framing brackets through which a means to secure the framing bracket  25  to the extension member  10  is provided. There are several parallel rows of holes such as depicted in  FIGS. 1 and 1A  through which the means to secure the framing member are provided. The means to secure may be a screw or nail or many other devices that are commonly found in the prior art. 
   In order to make sure that the framing bracket does not come off the lip of the door jamb a means to secure  30 A the framing bracket  25  to the top of door jamb is provided. This means to secure may be a screw or nail. 
   The extension members  10 , which extend from the doorjamb to the foot bracket  20 , are identical in length. 
   The framing brackets  25  and foot brackets  20  are equipped with a stop mechanism  15  within the device as depicted in  FIG. 4  to ensure that the length being used is uniform relative to each particular member. 
   The extension members  10  are inserted into the opening  7  that is provided in the framing bracket  25  and extends to the opening  7 , which is provided in the foot bracket  20 . The foot bracket  20  provides the anchor of this device and is installed using a screw  30  which is inserted through a hole in the foot bracket  20  and into the floor structure. The floor structure will probably be concrete. The foot bracket  20  with extension members  10  and framing bracket  25  secures the device to the door frame  5  and secures the device in one plane. 
   The foot brackets  20  themselves also have identical dimensions and include a stop mechanism  15 , which is designed into the interior of the foot bracket  20  to ensure that the extension members extend the same length into the foot bracket  20 . 
   No measurement is needed from the framing bracket  25  to the foot bracket  20  because the length of the extension members  10  are identical and dictate the placement of the foot bracket  20 . The worker at the job site does not need to measure the distance from the bottom of the door frame  5  to the placement of foot bracket  20 . In the old method an incorrect measurement from the bottom of the door frame  5  to the foot bracket  20  will produce an incorrect installation of the door. 
   Because no such measurement is necessary with this device and because of the uniform lengths of the extension members  10 , this device will eliminate one area of possible mistake in installation. 
   Additionally, in order to ensure that the frame  5  is completely square relative to the supporting structure a side member  8  is installed using a similar foot bracket  20 , which is placed and secured to the floor. Again, the foot bracket  20  on the side is installed in a similar manner and has a similar slot into which a side extension member  8  is inserted. A stop mechanism  15  is placed within this side foot bracket. The side extension member  8  extends from the slot in the foot bracket  20  to an existing hinge hole in the door frame  5  itself. The foot bracket is secured using a screw and the opposite end of the side member is secured to the door frame using a screw through the existing hinge hole in the door. This ensures that the door is installed correctly in that plane. 
   Due to the fact that there are methods to secure the device in all the planes, this provides a tight and secure fit to the device in the door frame  5 . 
   The worker at the job site would use three foot brackets  20  and install them into the flooring using an appropriate securing mechanism, probably a screw  30 . Two extension members would extend from the respective to the foot bracket  20  to the respective framing bracket  25 , which has been placed over the lip of the door frame. The worker would then install the side member  8  using similar steps. Because it is important to insure that the door frame  5  is installed correctly in one plane two extension members  10  should be used. 
   Because of its simplicity there is very little room for error in terms of measurement. Because of its durability, there is very little chance of damaging the unit. 
   While the embodiments of the invention have been disclosed, certain modifications may be made by those skilled in the art to modify the invention without departing from the spirit of the invention.
