2. Description of the Prior Art
Various types of work holders have been provided to support various entities while work operations are being performed. When a painter is faced with the task of painting a plurality of doors in a large building, conventional practice involves the doors being leaned against a vertical wall while one side of the door is painted and then the door is manually lifted and rotated 180.degree. and returned to its leaning position against a vertical wall while the other side of the door is painted. Usually, a paint applying technique is used which includes some type of power assisted paint application such as a conventional paint sprayer.
The prior art in this field of endeavor does not include a fixture which can effectively support a door that will enable the door to be rotatably adjusted about a generally central vertical axis to expose both sides of the door to a painting operation by merely rotating the door 180.degree. as incorporated into this invention and additionally, the prior art does not disclose a structure for frictionally and releaseably securing the door in its 180.degree. rotated positions.

Description of the Preferred Embodiment
Referring now specifically to the drawings, the door painting fixture of the present invention is generally designated by reference numeral 10 and includes a stand generally designated by reference numeral 12 which includes a lower arm assembly 14 and an upper arm assembly 16 which engage and support a door 18 from the center of the top and bottom edges thereof.
The stand 12 includes a vertically disposed, relatively short lower tubular member 20 in the form of a square tube which is rigidly connected to a transversely extending base member 22 with the tubular member 20 being perpendicular to and at the center of the base member 22 with the components being suitably welded together. The lower arm assembly 18 includes a tubular arm 24 rigidly attached to an edge of the base member 22 by welding in perpendicular relation thereto and in the same plane as the base member 22 with a reinforcing gusset plate 26 being connected to the perpendicular surfaces of the arm 24 and the tubular member 20. Telescoped into the tubular member 20 is a vertical standard 28 also in the form of a square tubular member with wing-type set screws or bolts 30 threaded into the tubular member 20 to detachably secure the standard 28 to the tubular member 20. The upper end of the standard 28 is provided with a tubular sleeve 32 welded to the upper end of the standard 28 at 34 with the open upper end of the tubular sleeve 32 telescopically receiving an upper standard 36 which is inserted into the sleeve 32 and secured detachably therein by wing-type set screws 38. The upper arm assembly 16 includes a depending tubular member 40 which telescopes over the upper end of the standard 36 and is detachably secured thereto by wing-type set screws or bolts 42. A laterally extending tubular arm 44 is pivotally connected between upwardly extending tabs or lugs 46 by a pivot bolt 48. The upper ends of the tabs or lugs 46 extend above the pivot bolt 48 and include a laterally extending bracket 50 which engages one end of a coil spring 52 which engages the upper surface of the arm 44 in spaced relation to the pivot bolt 48 to bias the arm 44 downwardly toward the lower arm 24 with the spring 52 enabling limited upward pivotal movement of the arm 44 and biasing the arm 44 downwardly. The end of the arm 44 which extends beyond the pivot bolt 48 in opposite relation to the spring 52 forms an extension handle 54 by which the arm 44 can be pivoted or the arm 44 can be grasped anywhere along its length and moved upwardly against the bias of the coil spring 52.
The lower arm 24 terminates at its outer end in a transverse tubular member 56 with an upstanding pin 58 welded thereto in alignment with the center of the arm 24 with the pin 58 having a pointed upper end 60. The upper arm 44 includes a depending pin 62 rigidly affixed thereto with the lower end of the pin 62 including a pointed end 64. The pointed ends 60 and 64 of the pins 58 and 62 are in vertical alignment and engage a point on the top and bottom edges of the door 18 respectively as illustrated in FIG. 1. The spring 52 enables the upper arm 44 and pin 62 to be moved upwardly sufficient to enable the door to be first engaged with the upper pin 62 and lifted upwardly with the bottom edge of the door then being swung inwardly and engaged with the pointed end 60 of the lower pin 58 with the spring 52 biasing the upper pin 62 and the door downwardly thereby securely mounting the door in the fixture to enable the door to be rotated about a vertical axis that may be centered or off-center in relation to the door so that both sides of the door can be exposed to a painter handling a paint applying device such as a paint sprayer 74 without the painter walking around the door or lifting the door and rotating it 180.degree. since the door 18 can be oriented with either side of the door facing the painter.
One end of the transversely extending member 56 is provided with a tubular member 66 perpendicular to the outer end of the tubular member 56 with the tubular member 66 having its center welded to the end of the member 56 and positioned in the same horizontal plane. Positioned above the tubular member 66 is an arcuately bowed rubber belt 68 having its ends adjustably received in tubular sleeve 70 welded on top of the tubular member 60 with wing-type set screws or bolts 72 being provided to adjustably clamp the ends of the arcuately bowed rubber belt in adjusted positioned thus varying the central height of the bowed belt 68 in order for the bowed belt 68 to frictionally engage the bottom edge of the door 18 in spaced relation to the pin 58 with the bowed belt providing sufficient resistance to rotational movement to retain the door in both of its 180.degree. rotated positions while the door is being painted thereby enabling the painter to use both hands when operating the paint applying equipment and enabling the door to be quickly and easily rotated 180.degree. to enable efficient painting of both surfaces of the door.
The knockdown structure of the stand enables the components thereof to be separated and stored or transported in a compact condition to enable it to be easily carried to a site of use. The fixture can be quickly and easily set up due to the telescopic connections and wing-type bolts securing the components in place. A door then can be quickly and easily positioned in the fixture by engaging the upper end edges of the door with the pin 62 with the upper pin being lifted upwardly along with the arm 44 about pivot bolt 48 by lifting the door upwardly with the spring 52 biasing the upper pin 62 and door 18 downwardly into engagement with the bottom pin 58. The door can then be painted completely on both sides and all edges. The size of the components may vary but the length of the arms 24 and 44 may be sufficient to support doors up to 48" in width which is usually the largest doors encountered. The transverse member 56 may be provided with end apertures to enable the stand to be temporaily anchored to a floor or other supporting surface. The door painting fixture enables a plurality of doors to be quickly and easily painted with the rotatable movement of the doors enabling all surfaces of the doors to be more uniformly and easily painted by using conventional spray equipment to apply various types of coating to the door such as lacquers, paints and the like.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and, accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
