ABSTRACT OF THE DISCLOSURE

A plastic door comprises inner and outer sub-assemblies. The inner sub- assembly includes the inner trim, panel, hardware mounting panel, window mechanism and other hardware which may be manufactured off line and attached to the outer sub-assembly as one of the final steps in the manufacture of the automobile on an assembly line.

Description

-" 3 :1 ~450~

BACKGROUND OF THE INVENTION
.. ..
While plastic doors for automobiles have been used, one oE the pro-blems involved is that they often are not sufficiently strong to meet Federal standards. ~nother problem has been that such plastic doors are of-ten not capable of providing means for receiving fittings and various hardware. In cases where the doors have been made capable to receive such fittings and hard-ware, the doors were completely sealed making it very difficult to service especially with respect to the installed window and window mechanism.
In assembling an automobile on a production line, much time is spent on the construction of the door. Cenerally, parts such as the handle, window and window mechanisms are put on at different s~ations. The final trim Eor the interior of the door generally takes considerable time and is done towards the end of the production line. The installation of such trim and hardware items often take more than one station and tends to ~low down the assembly line.
OBJECTS OF THE INVENTION
It is an object of this invention to provide an improved plastic door o:E increased strength for an automobile.
It is a further object of this invention to provide an improved plastic door capable of receiving standard fittings and hardware.
It is still a further object of this invention -to provide an improved plastic door wherein the parts within the door are readily serviceable after assembly.
It is still a further object of this invention to provide an improved automo~ile door wherein the trim) wi.ndow mechanism and other hardware may be assembled off line and installed as a unit onto an automobile coming off an assembly line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIM~TS
Referring particularly to Figure ], a plastic door 10 comprises an inner panel 12 ancl an outer panel 14. A window frame 16 including a window 18 is disposed between the inner and outer panels.
The exterior of the door 10 is somewhat conventional in appearance.
It may include a locking mechanism 20, a handle 21 to open and close a door latch, and a handle 22 to move the window 18 up or down.
The inner and outer panels 12 and 14 are built as separate sub-assemblies so that they may be made independently of each other. The inner panel 12 is designed to receive the hardware, such as the lock 20, handle 21, handle 22 and window 18 with its associated mechanism. The outer sub-assembly includ-ing the panel 14 may include the reinforcements for the door and be adapted to receive the inner sub-assembly as part of the final operation of assembly of the door on an assembly line.
Referring to Figure 2, the outer sub-assembly includes the outer panel 14 with a door beam 24 being secured thereto by adhesive or any outer suitable means. The beam 24 may be metal or glass reinforced fiber so as to give strength to the door especially in the event of side impacts. A halo pan~el 26 surrounds the beam 24 and includes various means for attachment of the inner panel assem-bly thereto.
The inner panel sub-assembly includes the inner panel 12 and a hardware mounting panel 28 secured thereto. The window frame 16 is secured to the hard-ware mounting panel 28. A window mechanism 30 is secured to the hardware mount-ing panel 28 and connected to move ~he window 18 up and down.
During the assembly of the automobile, the outer panel sub-assembly including the outer panel 1~, the beam 24 and the halo panel 26 may be separate-ly assembled along with the other parts of the automob~le. As one of the final `~ 3 ~450~

operations in the assembly of the door of the automobile, the i~mer panel sub-assembly includillg an inner panel 12, the hardware mounting panel 28 and winclow frame 16, along with various hardware including the window 18 and the window mechanism 30 may be assembled as a separate unit.
The entire inner panel assembly is thcn attach0d to the outer panel sub-assembly as one of the final steps in the assembly of the automobile. The inner panel sub-assembly may include various trim for the interior of the car.
While some hardware has been illustrated, it is apparent that the inner panel sub-assembly may be adapted to receive various addi~ional hardware including, for example, loud speakers for a radio, ashtrays and the like.
Referring particularly to Figure 3, the main parts for the inner sub-assembly are illustrated. The inner sub-assembly includes the inner panel 12, the window frame 16, the hardware mounting panel 28 along with various hardware items including the window mechanism 30. The window fram0 16 is secured to the hardware mounting panel 28 by means of mounting plates 32 having openings therein to permit attachment to the end 33 of the hardware mounting panel 28 which also includes apertures in alignment with the apertures upon the mounting plate 32.
Suitable screws (not illustrated) are inserted through the openings in the mounting plates 32 and 33 to provide mounting of the pieces. In like manner, 2Q mounting plates 34 are adapted to be comlected to the end 36 o~ the mounting panel 28 by means of screws or nuts or bolts (not illustrated) which extend through suitable openings in the plates 34 and openings in the end 36 of the mounting panel 28.
The window mechanism 3Q may be conventional in design with a pair of pivot arms 38 and 40 pivoted about a point 42. An arm ~4 is secured to hardware mounting panel 28 at mounting point 46. The pivo~ polnt 46 may be a molded piece molded when the hardware mounting panel 28 is molded so that it will be 5 0 ~

accurately positioned. When the panel 28 is secured to the inner panel 12, a section of plastic 47 is removed from between the main mountin~ panel portion and element including the pivot point 46. The ends of the lever arms 38 and 40 are connected to move the window 18 up and down. The handle 22 (Figure 1) is connected to a bracket 46 to drive a gearing member 48. Rotation of the handle 22 causes the movement of the gear member 48 to actuate the window mechanism to move the window 18 up or down in a conventional manner.
The hardware mounting panel 28 is secured within the frame of the inner panel 12. The mounting panel 28 may be secured to the panel 12 by adhe-sive or any other suitable means. The entire assembly illustrated in Figure 3 may be made off line from the main automobile includlng the outer door sub-assembly~ which could be installed in the car as one of the assembly steps.
The assembly of Figure 3 may include various trim and other hardware items secured to the inner panel 12. The entire sub-assembly illustrated in Figure 3 is adapted to be fitted to the outer panel assembly as part of the final opera-tion in the assembly of the automobile.
Referring to Figure 4, the three main parts of the outer sub-assembly include the outer panel 14, the reinforcement door beam 24 and the halo panel 26. The door beam 24 is secured to the outer panel 14 by means of adhesive or other means. The door beam 24 includes a pair of steel end connections 50 and 52. These connections extend into protruding end portions 57 and 59 of the halo panel 26. The steel end connections 50 and 52 are required for additional strength to permit the hinges of the door to be connected through suitable open-ings 54 at one end of the halo panel 26 and through opel-ings 53 in the connec-tion 52. Suitable screws may be used to provide the final attachment. The other end of the halo panel 26 receives the connection 50 with an aperture 51 for attachment thereto. The latch of the door is attached to the connection 50 ~ ~ ~4504 through an opening a~ the other end of the halo panel 26 and opening Sl.
All the parts illustrated in Figure 4 may be as an off line sub-assembled unit and installed in the car at the final station in the assembly line. The final step involves insertion of the inner panel assembly onto the outer panel assembl~r. This operation involves securing the inner door assembl)r over the halo panel 26. The attachment may be made by means of nuts or bolts.
It is noted that the halo panel 26 may be molded as a single piece and may include various protrusions and shapes necessary to receive any type of inner panel with its attached hardware. ln like manner, the outer panel 14 may be made as a single piece in a conventional plas-tic mold. With respect to the inner panel, the panel 12 is a single piece and may be formed by means of a conventional molding process. The hardware mounting panel 28 may also be molded conventionally and made in a variety of shapes and includes various e~tensions to receive any desired hardware thereon.
The window frame 16 is made of metal and zdds to the overall strength of the door.
It i.5 noted that one of the main features of the described cons~ruc-tion is that in effect it involves two sub-assemblies which ma~ be readily separated. Thus by removing a few nuts or screws, the entire inside panel sub-assembly of the door may be removed~ making the window and other hardware easily available and serviceable. In addition to the hardware illustrated~ the interior of the door between the panels may include various power units includ-ing speakers and wires for power windows.
