TECHNICAL FIELD
The present invention relates generally to vehicles and vehicle repair, and more particularly to an improved method and apparatus for the repair of certain types of original equipment interior door handles on vehicles.
BACKGROUND INFORMATION AND DISCUSSION OF RELATED ART
Some vehicles, including many Jeep Grand Cherokees from the 2004 to 2011 model years, and Jeep Commanders from the 2006 model year to the present, appear to have a weak area in the interior door handles, and many of the handles in these vehicles have broken over time. Unfortunately, the interior door handles on some of these vehicles are integrated into the door panel and are generally not serviceable by themselves, instead, the entire interior door panel has to be replaced in order to replace the door handle. For example, the interior door handle housing on the aforementioned Jeep vehicles is not attached with screws but is plastic welded into the door panel. On many other types of vehicles, the interior door handles are serviceable by themselves, which makes the repair much less expensive.
The foregoing information reflects the current state of the art of which the present inventor is aware. Reference to, and discussion of, this information is intended to aid in discharging Applicant's acknowledged duty of candor in disclosing information that may be relevant to the examination of claims to the present invention. However, it is respectfully submitted that none of the above-indicated information discloses, teaches, suggests, shows, or otherwise renders obvious, either singly or when considered in combination, the invention described and claimed herein.
SUMMARY OF THE INVENTION
The method and apparatus for the repair of vehicle door handles of the present invention provides an interior door handle repair kit that can be used to repair broken interior door handle assemblies on certain vehicles such as the Jeep Grand Cherokee (e.g., model years 2004 to 2011) and Jeep Commander (e.g., model years 2006 to the present). The inventive kit permanently solves the problem of prematurely broken door handles by replacing the brittle original equipment door handle support housing with a replacement housing constructed of very strong composite material, and includes all the components and fasteners necessary to repair the interior door handles on one or all of the doors, without having to replace the entire door panels.
The inventive method includes removing the original (broken) door handle housing from the back side of the door panel by drilling or otherwise removing the plastic rivets that secure the original handle housing to the door panel. The posts and tab(s) that extend from the back side of the door panel through corresponding apertures in the original housing are not removed, and are maintained for later use. After the rivets have been removed, the original door handle housing can be removed from the door panel and discarded. The replacement door handle housing is then installed on the back side of the door panel over the original posts and tab(s), and push nut retainers or other fasteners are placed over the posts and pushed down to press the flange of the replacement housing tightly against the back side of the door panel. A hole is drilled through the base of the tab, and a cotter pin or other fastener is inserted through the hole and bent around the tab to similarly secure the flange of the replacement housing tightly against the door panel.
The inventive repair kit preferably includes replacement interior door handle support housings for all four doors (driver's front door; driver's side rear passenger door; passenger side front door; and passenger side rear door); push nut retainers; cotter pins; and simple detailed instructions with pictures for installation. The original color for the kit components may be grey, tan, or other original equipment color, or the parts can be painted to match door panels, or may be used without matching colors. The components of the repair kit may be modified to provide a corresponding kit for other vehicles.
It is therefore an object of the present invention to provide a new and improved vehicle interior door handle repair kit.
It is another object of the present invention to provide a new and improved method for replacing the original equipment door handle housing with a replacement housing constructed of very strong composite material.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 through 3, wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved method and apparatus for the repair of vehicle interior door handles.
FIG. 1 is a front elevation view of a broken door handle assembly 10 on an interior door panel 12 of a vehicle. Door handle assembly 10 includes handle support housing 14 and handle lever 16.
FIG. 2 is a rear view of the original (broken) door handle housing 20 in the process of being removed from the back side of the door panel 12. Drill 22 is being used to drill out the plastic rivets 23 that plastic welded and permanently secured the original handle housing 20 to the door panel 12. Alternatively, a razor knife or other tool could be used to remove the rivets. Posts 24 and tab 26 extend from the back side of the door panel through corresponding apertures in the original housing, but are not removed, and are maintained for later use. After the rivets have been removed, the original door handle housing can be removed from the door panel.
FIG. 3 is a rear view of a replacement door handle housing 30 having been installed on the back side of the door panel 12 in place of the original. Push nut retainers 32 have been placed over the posts 24 and pushed down to press the flange 34 of the replacement housing tightly against the back side of the door panel. Alternatively, spring clips, locking tabs, or other fasteners could be used on the posts to retain the replacement housing against the door panel. A hole 36 has been drilled through the base of tab 26, and cotter pin 38 has been inserted through the hole 36 and bent around the tab to similarly secure the flange of the replacement housing tightly against the door panel. Alternatively or optionally, adhesive may be applied between the flange of the replacement housing and back side of the door panel (prior to tightening of the push nuts and placement of the cotter pin in the tab, if they are used) to provide bonding and help prevent gaps between the surfaces.
Typical customer instructions for the repair of broken interior door handles on a Jeep Cherokee type vehicle may include the following:
Tools required: drill, flat screwdriver, Phillips screwdriver, razor blade, and hammer, and a rag and a plastic adhesive are recommended. Note: Some minor modification of the door panel or handle kit may be necessary to ensure a perfect fit. This is an aftermarket part.
Step 1 (removing the door panel): Remove the screws from the door panel. After all of the screws are removed, carefully pry the panel from the door using the flat head screwdriver (use of a rag is recommended to protect the paint). The panel will pry loose with ample pressure (multiple clips attach the panel to the door). Once loose, lift up on the panel until it is above the lock mechanism. Once the panel is loose, carefully remove any electrical clips. Next, disconnect the rod that is attached to the door handle. Slide the clip to the side off of the rod. The plastic clip simply clips onto the rod. Once unclipped, the rod will lift out of the handle.
Step 2 (door handle removal): Start by lying the door panel down on a flat surface, backside facing up. Using a large drill bit, razor knife, or other tool, remove the tops off the plastic rivets (e.g., typically 6 rivets +/−). Carefully drill or cut only the rivets and handle housing as necessary, taking care not to drill through the door panel itself. Once all the rivets have been drilled or cut out, the handle housing will easily detach from the door panel. Use the razor blade to remove any excess plastic shavings on the panel.
Step 3 (installing the new handle on the door panel): Line the holes and slots of the replacement housing up with the posts (typically two) and tabs (typically 3-4) of the door panel. Press the housing down until it is flush with the panel (some minor modification may be necessary with the razor blade). Ensure that you are installing the correct handle (e.g., Driver/Front, Passenger/Rear, etc). An adhesive such as a two part epoxy or adhesive tape may be applied to one or more locations (such as the plastic weld locations) to help secure the replacement housing and eliminate gaps. Once the handle is lined up and pressed flush, using the flat head screwdriver (or a socket), press the provided push nut retainers down the posts until the handle housing is tight on the door panel. Next, use a 1/16th inch drill bit to drill through the base of the lowermost tab that protrudes through the bottom of the housing. Make sure the housing is pressed down flush when drilling the tab to avoid a gap between the housing and the door panel. Once drilled, insert the provided cotter pin. Using a screwdriver, bend and manipulate the cotter pin around the tab. Now that the handle housing is completely installed, you can replace the door panel on the vehicle. Follow the removal instructions in reverse.
Typical customer instructions for the repair of broken door handles on a Jeep Commander type vehicle may include the following. In this example, the original handle lever is to be removed and reused, and the instructions include steps for installation of the lever in the replacement housing.
Tools required: drill, flat head screwdriver, Phillips head screwdriver, razor blade, and hammer. Note: “Before” and “After” pictures are recommended to ensure that you install the handles in the correct direction. The housings appear similar; and incorrect installation may result in loss of hardware.
Step 1 (removing the door panel): Remove the screws from the door panel. After all of the screws are removed, carefully pry the panel from the door using the flat head screwdriver. The panel will pry loose with ample pressure. Once loose, lift up on the panel until it is above the lock mechanism. Once the panel is loose, carefully remove any electrical clips. Next, disconnect the rod that is attached to the door handle. Slide the clip to the side off of the rod (the plastic piece simply clips onto the rod). Once unclipped, the rod will push down and out of the handle.
Step 2 (removing the door handle): Start by lying the door panel down on a flat surface, backside facing up. Using a large drill bit, razor knife, or other tool, remove the top of the plastic rivets. Carefully drill or cut only the rivets and handle housing; do not drill through the door panel itself. Once all the rivets have been drilled or cut out, the handle housing will easily detach from the door panel. Use the razor blade to remove any excess plastic shavings on the panel.
Step 3 (removing handle from housing): The handle lever will be used in the new housing. To remove the handle lever, use a hammer and screwdriver to knock the pin out (watch spring carefully as it is under pressure). Once the pin is removed, the spring will fall out. You can now remove the handle lever and separate it from the old housing. Note: keeping pressure on the spring while removing the pin is helpful and will keep the spring from falling out. You may also remove the small rubber stopper from the old housing and place it into the corresponding tab on the replacement housing.
Step 4 (installing the handle in new housing): Start by inserting the handle lever into the new housing. This part can be tricky, but carefully insert and twist to allow the handle to fit into the housing properly. The use of force is not necessary. When faced with resistance, change your approach. Once the handle is inserted, line up the holes on the handle with the holes on the housing. The spring has two ends: one is straight and the other is bent. The side that is bent will be inserted into the handle and the straight side will rest against the housing. This will have the spring sticking out (pictures show the spring at rest and out of alignment as it should be). Now use your thumb to compress the spring into alignment and begin to insert the pin. Ensure that the pin goes through the housing, handle, and spring. Now take the small push nut retainer and press it over the pin until it reaches the housing. Once the pin is inserted all the way, and the retainer is attached, you can test the handle in the housing before moving on to the next step.
Step 5 (installing new handle on door panel): Line up the holes in the replacement housing with the posts (typically two) on the door panel. Ensure that the handle will be facing the correct direction before continuing. Press the housing down until it is flush with the panel. Note: some minor modification may be necessary with the razor blade. The driver's side and passenger side are different. Ensure that you are installing the corresponding housing. Once the handle is lined up and pressed flush, using the flat head screwdriver, or a deep socket that fits, press the provided push nut retainers down the posts until the handle housing is tight on the door panel. Do not apply enough pressure to bend or crack the housing. Now that the handle is completely installed, you can replace the door panel on the vehicle. Follow the removal instructions in reverse.
