Abstract

VEHICLE DOOR WITH SPLIT OUTER PANEL

ABSTRACT OF THE INVENTION
A split outer panel construction for a vehicle door includes an upper/outer panel member fixed to the window frame of the inner door panel. The lower edge of the upper/
outer panel includes a fin which fits within a slot formed in the upper inboard edge of a removably attachable lower/
outer panel member. Door hardware can be easily assembled onto the exposed inner panel prior to attaching the lower/
outer panel to the door.

VEHICLE DOOR WITH SPLIT OUTER PANEL

BACKGROUND OF THE INVENTION
1. Technical Field This invention relates to land vehicles and, more particularly, to doors for such vehicles.
2. Discussion Although a variety of door constructions have been proposed in the technical and patent literature, conventional pr~cttce ic for the door to include an inner and outer panel fixed together about its edges thereby forming a hollow ~hell in the interior lower portions thereof. The inner panel includes access openings to permit hardware such as window regulator mechanisms and the like to be inserted therethrough and attached during the typical on-line assembly process. Of course, thi6 tends to be an awkward operation for the worker and can lead to improper installation.

SUMMARY OF THE INVENTION
According to the present invention, the outer panel is split into two parts: an upper/outer panel member and a lower/outer panel member. The upper/outer panel member cover~ the window frame portion of the inner panel and is attached thereto. On the other hand, the lower/outer panel i8 removably attached to lower portions of the inner panel ~22~

and to the upper/outer panel member along adjacent longitudinal edges thereof. Accordingly, the door hardware can be assembled directly onto the exposed psrtions of the inner panel prior to attaching the lower/outer panel member.
In the preferred embodiment, the adjacent longitudinal-~, edges of the upper and lower/outer panel members are connected by way of an elongated fin depending from the upper member which is held in an inboard ~lot formed in the lower member. This construction provides a ~olid, yet removably attachable fastening method which reduces~
vibration of the ultimate assembly and insures a cosmetic fit.

BRIEF DESCRIPTION OF THE_~RAWINGS
The various advantages of the present invention will become apparent to those skilled in the art upon reading the following ~pecification and by reference to the drawings in which:
Figure 1 is an exploded perspective view of a vehicle door made in accordance with the teachings of the present invention;
Figure 2 is a partial perspective view of the completed door assembly with parts broken away;
Figure 3 is a partial cross sectional view along the lines 3-3 of Figure 2; and Figure 4 is a partial exploded perspective view with parts broken away illustrating the preferred mode of attachment of the various door parts.

DESCRI~ON OF_~E PREFERRED EMBODIMENT
The vehicle door lO of the present invention generally consists of three main parts: an inner panel 12 nnd a 6plit outer panel consisting of an upper panel member 14 and a lower panel member 16. The inner panel 12 is fairly typical and generally is formed from a metal stamping defining a lower hollow shell portion 17 and an upper window frame portion 18. As is known in the art, the lower shell portion 17 is provided with suitable attachment means onto which hardware (not shown) such as window regulator mechanisms, door lock assemblies and the like are attached. The window frame portion 18 also includes weather stripping (not shown) and the like as is well known in the art.
The upper/outer panel 14 is defined by three sides 20, 22 and 24 (which generally correspond with the sides of window frame 18) and a lower edge 26 that runs along the longitudinal length of the door at the belt line. Pursuant to a feature of this invention, lower edge 26 includes a depending fin 28 located inboard of the plane of the outer face 27 of the edge 26 as ceen most clearly in Figure 3.
Upper/outer panel 14, in this embodiment, is a sheet metal stamping and the fin 28 i6 formed by a reverse fold or Dutch hem as seen most clearly in Figure 4.
According to the method of this invention, the upper/
outer panel member 14 is attached to inner panel 12 80 that member 14 encloses the window frame 18. This can be accomplished in any of a well known number of ways.

~ 3 ~i~

Since upper panel member 14 is also a cheet metal stamping in this embodiment, conventional sheet metal attachment techniques can be used to permanently affix the two stampings together. In Figure 2 the outer/upper panel member 14 is shown hemmed to the window frame 18 portion of inner panel 12.
It will be appreciated that the partially assembled door still permits the on-line assembly worker to have access to the interior cavity 17 for mounting the necessary door hardware. This is because the lower panel ~ember 16 is not attached to the door until the hardware mounting operations have been completed. All ~uch operations can be conveniently accomplished from the exterior of the vehicle thereby greatly facilitating the assembly process.
once the door hardware has been assembled, the lower/
outer panel member 16 is detachably fastened to the inner panel 12 and to the upper/outer panel ~ember 14. Panel member 16 is preferably made from fiber-reinforced plastic and includes a pocket or slot 30 that is preferably integrally molded with the remainder of the panel and is located inboard from the outer face 31 thereof. A flexible seal 32 runs along the inboard wall 34 of Qlot 30. As can be seen most clearly in Figures 3 and 4, the space between seal 32 and the opposite wall 36 provides a receptacle for receiving the fin 28 of the upper panel member 14. The mating parts are dimensioned 80 that there is a rather tight fit substantially devoid of any relative movement which .. ~ , .....

1~22~

could cause rattling or other vibration related noise.
Thus, the joint along the adjacent longitudinal edges of the upper 14 and lower 16 outer panel members i~ not only cosmetically pleasing but also provides a mechanically sound fit.
Attachment around the other three edges of the lower/
outer panel member 16 can be accomplished by a variety of means. In the preferred embodiment, the plastic lower/outer panel 16 is provided with integral flanges 38 which are spaced from the inner 6urface 40 a sufficient distance to receive a tapping plate 42. The flange 38 has one or more openings 44 through which tangs 46 of plate 42 protrude thereby giving tapping plate 42 a certain range of adjustment. Plate 42 includes an internally threaded boss 48 for receiving the threaded chank of a fastener 50 whose enlarged head draws the inner panel 12 and lower/outer panel member 16 together upon tightening.
Those skilled in the art can appreciate that the present invention provides significant advantages over conventional door constructions and that modifications of the previously discu sed preferred embodiment can be readily made without departing from the ~pirit of this invention after having the benefit of reading the foregoing specification and studying the drawings. Therefore, w~ile this invention has been described in connection with a particular example, no limitation is intended thereby except as defined in the appended claims.
