Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a rack for holding doors that are painted while held by the rack.




2. Background of the Prior Art




During new construction, such as a house or office complex, a few doors to many dozen doors will need to be painted or otherwise finished. Typically, each door is finished prior to being installed within the opening which the door will serve. One method of door finishing commonly employed is to rest the door on one of its surfaces and finish the opposing surface. After the surface is painted, the door is flipped and the unfinished surface of the door is then finished. The problem with such a method is that it is time-consuming and requires excessive handling of the door. Additionally, as the door is generally slanted during the finishing process, excess paint or other finish can tend to collect in a particular location resulting in an uneven finish.




In order to address such problems, door painting racks have been proposed wherein the door is hung from a rack and is completely finished while held within the rack. While such prior art devices work with varying degrees of efficiency, they tend to suffer from one or more drawbacks.




Many door painting racks are unusually complex in design and construction, making the racks expensive to manufacture and time-consuming to assemble and use. Other devices have limited functionality, thereby making such racks of limited value to a painter.




Therefore, there exists a need in the art for a door painting rack that allows for relatively quick and easy finishing of a large number of doors. Such a rack must not be unusually complex in design and construction, so that the rack is relatively inexpensive to manufacture and is quick and easy to assemble and use. The rack must be versatile for use with a wide variety of doors and in various settings.




SUMMARY OF THE INVENTION




The door painting rack of the present invention addresses the aforementioned needs in the art. The door painting rack allows a painter to finish a large number of doors quickly and easily. The rack is relatively simple in design and construction, so that the rack is relatively inexpensive to manufacture and is quick and easy to assemble and use. The rack can be used with a wide variety of doors and can be used a variety of settings.




The door painting rack of the present invention is comprised of a base member having a first lower support pin attached thereto. An extension support extends upwardly from the base member while a first extension arm extends outwardly from the extension support. A first spring-loaded upper support pin is attached to the first extension arm and faces the first lower support pin. The base member can be comprised of a first leg and a second leg that extends outwardly from the first leg and is generally parallel with the extension arm such that the first lower support pin is attached to the second leg. The second leg may be telescopic. A third leg extends outwardly from the first leg in opposing direction relative to the second leg. The third leg can be telescoping. A second lower support pin can be attached to the third leg while a second extension arm extends outwardly from the extension support in opposing direction relative to the first extension arm. A second spring-loaded upper support pin is attached to the second extension arm and faces the second lower support pin. A first stop is attached to the second leg while a second stop is attached to the third leg. The first extension arm is fixedly attached to the extension support and the second extension arm is fixedly attached to the extension support. The extension support may be telescoping.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings, it is seen that the door painting rack of the present invention, generally denoted by reference numeral


10


, is comprised of a base member


12


. The base


12


can have any desired configuration such as the illustrated leg configuration wherein a plurality of legs extend outwardly from a central point. The illustrated base member


12


has a first leg


14


and a second leg


16


extend outwardly from a point in generally opposing directions (the first leg


14


and the second leg


16


can be viewed as a single long leg) while a third leg


18


and a fourth leg


20


(which can also be viewed as a single long leg) extend outwardly from the joinder point of the first leg


14


and the second leg


16


, or from any other point along either the first leg


14


, the second leg


16


or both. Various other leg configurations as well as other base member


12


configurations (a single flat base member


12


, for example) are possible in keeping within the scope and spirit of the present invention


10


,




In a leg-based base member


12


configuration, the base member


12


can be a single unit, or as seen, the base member


12


can be a single sub-base frame member


22


onto which each of the various legs


14


,


16


,


18


, and


20


are removably attached. Attachment of each leg to the sub-base frame member


22


can be accomplished in any standard fashion such as by providing openings


24


on the particular leg which openings


24


are aligned with openings


26


on a section of the sub-base frame member


22


and a pin


28


is passed through the aligned openings


24


and


26


. If desired, a washer


30


can be affixed to the pin


28


and a cotter pin


32


can be passed through the pin


28


so that the pin


28


is not easily removed. By providing more than one set of openings


24


on the particular leg (or on the sub-base frame member


22


) that particular leg becomes telescoping, although only working legs—legs that receive a door D thereon—need to be made telescoping. An advantage of having removable legs attachable to a sub-frame


22


is that it allows the door painting rack


10


to be disassembled for ease in transport and storage.




A lower support pin


34


is attached to the base member


12


at any desired location. If the door painting rack


10


is configured to receive more than one door D, then, one or more additional lower support pins


34


will be located on legs other than the leg to which the first lower support pin


34


is attached. If the leg configuration illustrated in

FIGS. 3-5

is used, then a lower support pin


34


will be located on the first leg


14


and the opposing second leg


16


. If a multiple door holding configuration is desired, for example a four door configuration, then a lower support pin


34


will be located on each of the four legs


14


,


15


,


18


, and


20


. A stop


36


will be located on the base member


12


, one stop


36


for each lower support pin


34


that is located on the base member


12


.




An extension support


38


extends upwardly from the base member


12


. The extension support


38


may be either of fixed height or may be telescoping in any desired fashion such by providing an opening


40


on one of the sections


42




a


of the extension support


38


and providing an adjustment handle


44


that is threadably secured to this section


42




a


and that friction engages with the other section


42




b


of the extension support


38


. In order to adjust the height of the extension support


38


, the two sections


42




a


and


42




b


are positioned relative to one another to the desired height and the adjustment handle


44


is rotated until it engages the second section


42




b


of the extension support


38


and thereby friction holds the two sections


42




a


and


42




b


relative to one another. If a different height is desired, the adjustment handle


44


is counterrotated in order to disengage from the second section


42




b


, the two sections


42




a


and


42




b


are repositioned, and the handle


44


is again rotated in order to once again engage the second section


42




b.






A first extension arm


46


extends outwardly from the extension support


38


and is secured to the extension support


38


in fixed fashion. If the door painting rack


10


is configured to hold more than one door D, additional extension arms


46


are provided, one extension arm


46


for each door D that the device


10


is designed to hold at one time. If the legs of the base member


12


are telescoping, then each extension arm


46


is telescoping to correspond with its respective leg. The telescoping nature of each extension arm


46


is accomplished in any desired fashion such as by providing a pair of openings


48


on a first section


50




a


of the extension arm


46


and providing a series of opening pairs


52


on a second section


50




b


of the extension arm


46


and aligning the openings


48


on the first section


50




a


with a pair of openings


52


on the second section


50




b


and passing a pin


54


through the aligned openings


48


and


52


. A washer


56


may be placed on the pin


54


while a cotter pin


58


may be passed through the pin


54


in order to hold the pin


54


in position.




A spring-loaded upper support pin


60


is attached to the each extension arm


46


and aligns with and faces the lower support pin


34


found on the base member


12


. The upper support pin


60


passes through corresponding openings


62


located on the extension arm


46


and has a shaft


64


, and a head portion


66


. The shaft


64


slides through the openings


62


, while a compression spring


68


biases the shaft


64


in a downward orientation. The spring


68


is located within the extension arm


46


and abuts the upper inner surface and the lower inner surface of the extension arm


46


, with washers


70


disposed between the ends of the spring


68


and the respective inner surfaces and of the extension arm


46


. A cotter pin


72


is passed through the shaft


64


under washer


70


and prevent the shaft


64


from being overextended through the openings


62


.




in order to use the door painting rack


10


of the present invention, the extension support


38


is adjusted to the desired height to accommodate the size of the door D to be held by the device


10


. Each leg that is to support a door D is adjusted to its desired length (if telescopic) and the corresponding extension arm


46


is also adjusted to a corresponding length so that the lower support pin


34


and the upper support pin


60


are vertically aligned. A door D is positioned within the door painting rack


10


by pushing on the upper support pin


60


upwardly causing the upper support pin


60


to move upwardly. The door D is then rested on the lower support pin


34


and the spring


68


of the upper support pin


60


biases the upper support pin


60


on the door D thereby holding the door D in position within the device


10


. The stop


36


located on the base member


12


prevents rotation of the door D. The door D is now ready to be finished in desired fashion. In order to remove the door D from the door painting rack


10


, the door D is lifted upwardly causing the upper support pin


60


to move upwardly. Once the door D is clear of the lower support pin


34


, the door D is removed from the device


10


.




For transport of the device


10


, the various components are disassembled, and the device


10


is transported and reassembled at the next location.




While the invention has been particularly shown and described with reference to an embodiment thereof, it will be appreciated by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
