Patent Application

During the course of their work, professional painters typically paint or otherwise finish doors, of the type commonly found in houses and other buildings, either installed in the frame or leaning against the wall or other structure. Finishing a door in the vertical position, especially when using an airless or other type paint sprayer, can result in runs or sags in the finish due to gravity, overspraying onto adjacent surfaces, and an improper viewing angle for the painter.
Furthermore, because a typical construction site can range from very cluttered and dirty to well-maintained, but is rarely pristine, a door resting on or near the floor may have dirt or debris from the floor blown onto it by the sprayer as the finish is applied. If the door being finished is leaning against another structure, the finish must be applied to first one side, allowed to dry, turned, and the finish applied to the other side, a very time consuming process.
The prior, but not necessarily relevant, art is exemplified by Wood U.S. Pat. No. 5,090,648, Ray U.S. Pat. No. 5,164,011, and Speed et al. U.S. Pat. No. 6,090,204.

These and other objects and advantages of the present invention will become readily apparent to those persons skilled in this particular area of technology and to others upon reading the following specification and the accompanying drawings.
The painter's portable jig 1 according to the present invention is described in connection with
The main components of the jig 1 comprise a pair of elongated side members 2 and 3, a pair of cross members 4 and 5, and an adjustable squaring mechanism 6 for maintaining the assembled components 2, 3, 4 and 5 in a perpendicular arrangement.
The disassembled jig components 2, 3, 4, 5 and 6 may be stacked in a convenient arrangement for transportation or storage, and held together with eye bolts and wing nuts (not shown).
The side members 2 and 3 are pre-drilled with various holes 13, 14, 15, 16, 17 and 18 to accommodate different sizes of doors 9. Preferably, but not necessarily, there are provided: a pair of pre-drilled holes 13 and 14 to accommodate a door 9 that is 6′8″ long; a pair of pre-drilled holes 15 and 16 to accommodate a door 9 that is 7′0″ long; and a pair of pre-drilled holes 17 and 18 to accommodate a door 9 that is 8′0″ long.
The door 9 is placed in the jig 1 and pivotally mounted thereon by two centrally-located pivot mechanisms 19 and 20, such as knob-handled lag screws, which pass through a pre-drilled hole 21 or 22 in their associated cross members 4 or 5, and then through the space 23 or 24 between the cross members 4 or 5 and the door 9, and then into the door 9 itself.
The jig 1 provides predetermined spaces or clearances 23, 24, 25 and 26 between the door 9 and the components of the jig 1. In this manner, the door 9 may be pivoted or rotated from one surface to another without interference with the cross members 4 and 5 or the side members 2 and 3.
A door stabilizing mechanism 27 is provided to hold the door 9 in a horizontal arrangement when one of its major sides is being finished or painted. Preferably, but not necessarily, the door stabilizing mechanism 27 comprises a pre-drilled hole 28 at a predetermined location in a cross member 4, cooperating with a knob-handled lag screw 29 which passes therethrough into the door 9. This door stabilizer mechanism 27 holds the door 9 in the horizontal position while a major surface of the door 9 is being painted. When it is desired to rotate or flip the door 9 so that the opposite major surface can be painted, or the edges of the door 9 can be painted, the door stabilizing mechanism 27 is temporarily removed to permit pivoting of the door 9.
The cross members 4 and 5 can be releasably assembled to the side members 2 and 3 by any suitable releasable connecting mechanisms 43, such as pins, D-rings, bolts, etc.
The portable jig 1 as described above can be supported, if desired, on conventional saw horses, and disassembled for transportation and/or storage in a convenient package. However, a preferable arrangement involves the unique disassemblable leg assemblies 7 and 8 described hereinbelow.
Preferably, but not necessarily, each leg assembly 7 or 8 comprises two vertical members 30, 3 or 32, 33 welded orthogonally to two cross leg members 34, 35 or 36, 37, respectively. The top portions of the vertical leg members 30, 31, 32 and 33 may be releasably secured to the end of the jig side members 2 and 3 by suitable bolts 38 and wing nuts 39. To maintain the leg assemblies 7 and 8 in orthogonal arrangement with the jig side members 2 and 3, there is provided a pair of angled support members 40 and 41 for securement to one of the jig side members 3. Such angled support members 40 and 41 are releasably secured to the jig side member 3 and a vertical leg member 31 or 33, respectively, by releasable D-pins 42.
Although only two angled support members 40 and 41 are shown in the drawings, there can, of course, be three or four such members used if desired.
It should be appreciated that upon disassembly, the leg assemblies 7 and 8 and the components of the portable jig 1 can all be disassembled conveniently for storage and/or transportation, and assembled on site with a minimum of effort.
It will be appreciated that after the doors 9 have been painted or finished using the apparatus shown in
The drying rack 50 includes an elongated L-shaped member 51 which is secured to a common saw horse 52 with screws 53. Such L-shaped member 51 may preferably, but not necessarily, comprise a 1½ inch by 1½ inch by 48 inches long by {fraction (1/8)} inch thick angled aluminum member. The upper edge 63 of the L-shaped member 51 is provided with a series of cutouts 54 to accommodate T-handle screws or lag bolts 55 and 56. Such T-handle screws or lag bolts 55 or 56 are positioned centrally in the door edge where the central pivot mechanisms 19 and 20 shown in
