Description




BACKGROUND ART




1. Field of the Invention




The invention relates to an article used in the manufacture of assemblies. More specifically, the invention relates to an article used to maintain a component of an assembly in a position with respect to the remainder of the assembly during surface treatment processes of a manufacturing process.




2. Description of the Related Art




Complex assemblies often have components that have surfaces that need to be treated at some point in the manufacturing process. Treating or coating these surfaces require decisions on how and when in the manufacturing process this is to occur.




The decision of how and when to treat and/or coat (“coated”) assemblies increases in complexity when components of the assembly are designed to move with respect to each other. An example of such an assembly is a motor vehicle. The doors of the motor vehicle must be coated in a similar manner as the body of the motor vehicle. To ensure they look the same, i.e., they are painted the same, the two components should be coated at the same time.




Because the best way to ensure the door and body of a motor vehicle are coated the same way is to do them at the same time, a decision must be made with regard to assembly. More specifically, a decision must be made as to whether the doors are to be secured to the body after the coating process has cured or before the coating portion of the manufacturing process has begun.




If the doors are to be secured to the body after the components are treated, the process may damage the coatings that were already applied to the components. If the door is secured before, the coating on the door may bond to the coating on the body resulting in either an immovable door or a door and a body with a flawed coating and surface.




A resolution to this matter has typically included the step of coating the door and the body of the motor vehicle after the door is secured to the body. Referring to

FIG. 9

, one embodiment of a door positioning article of the prior art is shown at


20


. This embodiment


20


is fabricated from sheet metal so it is abrasive. The embodiment


20


includes a catch


22


that receives a striker from a door (neither shown) therein. This embodiment


20


requires the striker to be assembled prior to coating. This may increase the costs associated therewith because strikers typically are not coated.




A second embodiment of the prior art is shown at


24


in FIG.


10


. The second embodiment


24


includes a securing end


26


for securing the second embodiment


24


to the body of the motor vehicle. A door is slid over a distal end


28


and secured in place with stops


30


. A handle


32


is pushed downwardly to release the door from the second embodiment


24


, which is subsequently forced off the body of the motor vehicle with a quick downward force applied thereto. The second embodiment


24


requires a sheet metal configuration. This material requirement and design promotes faults in the coatings of both the body and the door. More specifically, forcing the second embodiment


24


into and out of position creates unsightly and highly visible marks that compromise the integrity of the coating by allowing contaminants to reach the material being coated.




SUMMARY OF THE INVENTION




A door positioning article positions a door of a motor vehicle in an ajar position with respect to the motor vehicle. The door positioning article is used during coating processes for the door and the motor vehicle. The door positioning article includes a base defining a longitudinal axis. An extension is secured to the base for fastening the door positioning article to the motor vehicle. A retainer extends out from the base and holds the door in the ajar position with respect to the motor vehicle and the door positioning article. A spring extends between the base and the retainer for allowing the door to pass over the retainer and for forcing the retainer through an orifice in the door providing the defined ajar position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT





FIGS. 1 through 8

illustrate several embodiments of the invention. Elements that are similar throughout the Figures will have similar reference characters offset by one hundred. To the extent the elements are similar between embodiments, the description for each element will not be repeated.




Referring to

FIG. 1

, a portion of a motor vehicle


34


is shown. The motor vehicle


34


includes a body


36


and a door


38


. The door


38


pivots about a door hinge (not shown) disposed adjacent a hinge end


40


of the door


38


. As is shown in

FIG. 1

, the door


38


is in an ajar position because it is open with respect to the body


36


of the motor vehicle


34


.




The invention, a door positioning article, is generally indicated at


42


in the Figures. The door positioning article


42


maintains the door


38


in the ajar position as is indicated in FIG.


1


. The door positioning article


42


is fabricated from a thermoset polymer. The material chosen is one that can maintain its shape and integrity during the coating process, which includes curing steps in ovens at high temperatures.




The door positioning article


42


includes a base


44


that defines a longitudinal axis


46


, shown in FIG.


3


. The base


44


is longitudinal in character. The base


44


includes a channel


48


that extends through a portion of the base


44


. While it should be appreciated that the channel


48


may extend through the entire base


44


, the embodiments shown in the Figures show the channel


48


extending through only a portion thereof. For reasons to be discussed subsequently, the third embodiment


242


shown in

FIGS. 7 and 8

have a base


244


that is void of having a channel.




An extension


50


extends out from the base


44


. The extension


50


includes two halves that are bifurcated by the channel


48


. The extensions


50


may be symmetrical. The design of the extension


50


is due in large part to the design of the motor vehicle


34


and, in particular, the side of the door jamb


52


. When the door jamb


52


is designed to require a different or non-symmetric extension


50


, a different or non-symmetric extension


50


will be incorporated into the invention


42


.




The extension


50


may include a hole


54


extending therethrough. The hole


54


provides access to the space behind the extension


50


. Oftentimes, the door positioning article


42


is secured to the door jamb


52


over a hole (not shown) in the door jamb


52


that exists to allow a striker bar to be mounted to the door jamb


52


. Access is required for certain situations including, but not limited to, e-coating the inside surface of the sheet metal that is used to manufacture the door


38


.




Extending down from the extension


50


is a securing projection


56


. The securing projection


56


engages the doorjamb


52


, typically through a hole. The configuration of the securing projection


56


,


156


,


256


varies with the configuration of the doorjamb


52


and the requirements dictated by the manufacturer of the motor vehicle


34


. As may be seen in

FIGS. 7 and 8

, a Christmas tree styled protrusion


256


is required.




The door positioning article


42


includes a retainer


58


that extends out from the base


44


. The retainer


58


holds the door


38


in its ajar position with respect to the motor vehicle


34


and the door positioning article


42


. The ajar position is shown in FIG.


1


.




The retainer


58


defines a protrusion


60


. The protrusion


60


is designed to be received by a door hole


62


(FIG.


2


). The protrusion


60


positively engages the door


38


by extending into the door hole


62


. The protrusion includes two sides


64


,


66


that create an apex


68


. The two sided design is utilized in the preferred embodiment because it is bidirectional. More specifically, using two sides


64


,


66


that form an apex


68


allow the door


38


to be moved over the protrusion


60


in both directions with the same amount of force required allowing the door


38


to be moved into and out of the ajar position.




The retainer


58


includes a hinge


70


. The hinge


70


is at one end of one of the sides


66


opposite the apex


68


of the protrusion


60


. The hinge


70


allows the retainer


58


to flex as the door


38


is moved into and out of the ajar position. The hinge


70


allows the retainer


58


to move closer to the base


44


as the door


38


passes thereby.




A spring


72


is fixedly secured to one end of the other of the sides


64


opposite the apex


68


of the protrusion


60


. The spring


72


allows the retainer


58


to move back and forth as the door


38


moves into and out of the ajar position, the movement of which requires the door


38


to pass over the retainer


58


.




A supporting member


74


extends between the base


44


and the retainer


58


. The supporting member


74


extends upwardly from the base


44


at an angle. The supporting member


74


is secured to the retainer


58


at a position disposed adjacent the hinge


70


. Together with the spring


72


, the supporting member


74


holds the retainer


58


with respect to the base


44


.




The door positioning article


42


also includes an overslam stop


76


. The overslam stop


76


defines a stop surface


78


that prevents the door


38


from moving past the retainer


58


. Therefore, when the door


38


is closed with excess force, e.g., when it is slammed shut, the stop surface


78


will prevent a door flange


80


(

FIG. 2

) from moving therepast which will, in turn, prevent the door hole


62


from moving past a position that will allow the protrusion


60


to engage the door hole


62


. In the preferred embodiment, a solid wall


82


extends behind the stop surface


78


to provide additional support to the stop surface


78


.




Extending out from the base


44


is a jam prevention leg


84


. The jam prevention leg


84


includes three portions


86


,


88


,


90


. A first portion


86


is to the base


44


. A second portion


88


is secured to the first portion


86


and extends out therefrom at an angle askew thereto. A third portion


90


is secured to the second portion


88


and extends out therefrom at an angle askew thereto. In the embodiments shown in

FIGS. 2-4

,


7


and


8


, the first


86


and third portions are parallel to each other. In the embodiment shown in

FIGS. 5 and 6

, the jam prevention leg


184


only includes a single portion that is flat. The jam prevention leg


84


prevents the door


38


from being jammed into the doorjamb


52


moving the door positioning article


42


out of alignment resulting in the misalignment of the protrusion


60


with respect to the door hole


62


.




The invention has been described in an illustrative manner. It is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation.




Many modifications and variations of the invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the invention may be practiced other than as specifically described.
