The present invention relates generally to a retainer clip, and in particular to a retainer clip for use with a handle bezel on a vehicle closure and a method of installing the handle bezel.
In many conventional automotive vehicles, at least one of the passenger doors has a handle bezel with an opening for inserting a key into a key cylinder in order to unlock the door latch. This is also true for the lift gates and similar cargo closures on station wagons, sport utility vehicles and vans. In addition, the key cylinder on the rear openings are generally keyed to unlock with the same key as the passenger doors.
The end gates (also called lift gates) of conventional pickup trucks, on the other hand, did not include locks. More recently, however, end gates in some pickup trucks have added a lock cylinder for locking the end gate latch. The addition of a lock cylinder adds extra steps in the assembly process since now a key cylinder needs to be assembled to the handle bezel of the end gate before the bezel is mounted to the end gate. Moreover, the additional key cylinder for the end gate is preferably brought to the vehicle at the same time as the key cylinder for the passenger door(s) in order to assure that a matched set (a set that will use the same key) is assembled to each vehicle. An extra assembly station in the assembly plant can be added to accomplish these tasks, but this can be undesirable from both a cost and an assembly process standpoint. The matched key cylinders can also be tracked separately in the plant, but this is generally undesirable from both a cost and assembly process standpoint.
Some end gates on pickup trucks include an access panel on the inner surface adjacent to the latch handle, providing access to a securing means within the end gate for the handle assembly as well as the handle bezel and lock cylinder. This may allow for assembly at a single station. However, not all end gates include such an access panel, and this may not always eliminate the need for another assembly station.
Another option is to provide a fastener that will secure the handle bezel on the outer surface of the end gate by extending through the bezel and engaging the end gate. This is not only less aesthetically attractive, but this would somewhat defeat the purpose for adding a lock on the end gate in the first place since one may be able to defeat the lock by unscrewing the fastener and removing the handle bezel to unlatch the end gate.
Thus, it is desirable to have some means on the inner surface of the end gate to allow one to release the handle bezel when needing repair, while preventing the bezel from being released and removed from the outer surface of the end gate. Preferably, this is accomplished while still allowing for flexibility in the timing and station at which the handle bezel is installed on the end gate in the assembly plant.
An embodiment contemplates a handle bezel for use on a closure of a vehicle. The handle bezel may include a bezel body having an opening adapted to receive a handle; a retainer bracket extending outward from the bezel body and including a support flange; and a retainer clip mounted to the retainer bracket and including a main surface having a fastener opening extending therethrough, and a plurality of fastener retention tabs extending generally radially inward into the fastener opening and extending out of plane to the main surface, with the plurality of fastener retention tabs adapted to slidably engage a fastener mounted to the closure when the handle bezel is biased toward the closure and securingly engage the fastener mounted to the closure when the handle bezel is biased away from the closure.
An embodiment contemplates a closure of a vehicle. The closure of the vehicle may have an outer surface including a handle opening, and an inner surface in opposed relation to the outer surface. A latch handle assembly is located within the handle opening, has a handle portion, and is secured to the inner surface. A fastener extends through the inner surface toward the outer surface. The closure may also have a handle bezel including a bezel body having an opening that receives the handle portion; a retainer bracket extending outward from the bezel body; and a retainer clip mounted to the retainer bracket and including a main surface having a fastener opening extending therethrough, and a plurality of fastener retention tabs extending generally radially inward into the fastener opening and extending out of plane to the main surface, with the fastener retention tabs slidably engaging the fastener when the handle bezel is biased toward the closure and securingly engaging the fastener when the handle bezel is biased away from the closure.
An embodiment contemplates a method of assembling a handle bezel to a vehicle closure having an outer surface and an inner surface, the method comprising the steps of: assembling a latch handle assembly to the vehicle closure with at least one fastener extending through the inner surface and extending toward the outer surface; slidably inserting a handle bezel through a handle opening in the outer surface around a handle portion of the latch handle assembly; slidably engaging a retainer clip mounted to the handle bezel around the fastener as the handle bezel is axially moved toward the outer surface; and engaging fastener retention tabs on the fastener such that axially sliding disengagement of the retainer clip from the fastener is prevented.
An advantage of an embodiment is the flexibility provided in determining when and where, in an assembly plant, the handle bezel is assembled to the end gate (closure). This may reduce costs by avoiding the need to separately sequence the assembly of the end gate key cylinder, eliminating the need to install a separate fastener specifically for the purpose of securing the handle bezel to the end gate, and/or eliminating the need for a separate assembly station.
An advantage of an embodiment is that the key cylinder can be installed to the handle bezel and then located with the vehicle for later assembly in order to assure that the end gate key cylinder is matched to a passenger door key cylinder. The handle bezel (with key cylinder) can then be assembly to the end gate at the most advantageous location in the assembly process.
An advantage of an embodiment is that the handle bezel and key cylinder require access to the inner surface of the end gate in order to be removed, thus maintaining the theft deterrence function while still allowing for repair and replacement of the handle bezel and key cylinder.
The outer surface 12 includes a handle opening 16, around which are located three tab slots 18. The inner surface 14 includes three fastener holes 20 opposite the handle opening 16. The upper two of the three fastener holes 20 receive a pair of top fasteners 22, while the lower of the three fastener holes 20 receives a bottom fastener 24. The fasteners may be, for example, bolts or screws.
A latch assembly 26 assembles into a latch handle assembly 28. The latch handle assembly 28 may be assembled to the end gate 10 by inserting the latch handle assembly 28 into the handle opening 16, connecting the latch handle assembly 28 to latch rods 32, and then securing the latch assembly 26 to the end gate 10 by inserting the fasteners 22, 24 through the fastener holes 20 and screwing them into fastener holes 30 in the latch assembly 26. The latch rods 32 may engage catches 34 (only left side shown) that operatively engage the vehicle to hold the end gate 10 in its closed position. The catches 34 are selectively releasable by the latch handle assembly 28 to allow the end gate 10 to pivot about hinges 36 (only left side shown) into an open (horizontal) position.
A handle bezel 40 includes main body 41 with a handle opening 42 for receiving the handle portion 44 of the latch handle assembly 28 therethrough. The handle bezel 40 can be installed immediately after or during installation of the latch handle assembly 28, or at a later time. The handle bezel 40 has three integral tabs 46 extending from the main body 41 that are located to align with and slide into the tab slots 18 when the handle bezel 40 is in the correct location and orientation relative to the handle opening 16. Each of the integral tabs 46 may include a retention spring 48 mounted thereon to provide a biasing force to help retain the integral tabs 46 in their respective tab slots 18.
The handle bezel 40 also includes a mount 50 for mounting a key cylinder 52 thereto. The key cylinder 52 engages with the latch handle assembly 28 to lock and unlock the assembly based on which direction a key (not shown) is turned in the key cylinder 52. The key cylinder and its engagement with the latch handle assembly 28 may be conventional, if so desired, and so will not be discussed or shown in more detail herein.
In addition, the handle bezel 40 includes a retainer bracket 54 extending from the main body 41. The retainer bracket 54 is located to align with—and has support flanges 56 that are located to extend partially around—the bottom fastener 24 when the handle bezel 40 is mounted to the end gate 10. A retainer clip 58 mounts in the retainer bracket 54. It has mounting flanges 60 that are received in slots 57 of and supported by the support flanges 56. A pair of bracket retention tabs 62 extend from the retainer clip 58 and engage with the slots 57 to prevent the retainer clip 58 from sliding out of the support flanges 56. A stiffening flange 64 extends from the retainer clip 58 and is located between the slots 57. The stiffening flange 64 helps minimize the flexing of the retainer bracket 54 when out of plane forces are applied to the bracket 54.
The retainer clip 58 also includes a fastener opening 66 in a main surface 70, with fastener retention tabs 68 extending radially inward toward the center of the opening 66. The fastener retention tabs 68 are angled out of plane from the main surface 70. The fastener retention tabs 68 are oriented to extend radially inward and aft when the handle bezel 40 is mounted in the end gate 10, with the fastener retention tabs 68 extending radially inward far enough to engage with threads on the bottom fastener 24.
Assembly of the handle bezel 40 to the end gate 10 may include assembling the key cylinder 52 to the handle bezel 40 at the same time as a key cylinder (not shown) for a passenger door (not shown) is installed in that door so that the key cylinders will unlock with the same key (not shown). The handle bezel 40 for the end gate 10 may then be kept with the vehicle until such time as it is desirable to install the handle bezel 40 to the end gate 10. Of course, other sequencing may be employed in the assembly plant instead, if so desired.
The handle bezel 40 is assembled to the end gate 10 by aligning each integral tab 46 with its corresponding tab slot 18 and pushing it into position. While pushing it into position, the retention springs 48 on the integral tabs 46 will each engage with its corresponding tab slot 18, and the retainer clip 58 will slide over the bottom fastener 24, with the fastener retention tabs 68 engaging the threads of the bottom fastener 24. The bottom fastener 24 will already have been installed previously while securing the latch assembly 26 to the end gate 10.
The retainer clip 58 on the retainer bracket 54 of the handle bezel 40, then, allows one to assemble the handle bezel 40 to the end gate 10 without having to lower the end gate 10, and without having to add—or remove and reinstall—any additional fasteners to secure it in place. Accordingly, once the vehicle reaches a final trim station in an assembly plant, for example, the handle bezel 40 can be assembled to the end gate 10, even though a lock cylinder for a passenger door and the latch handle assembly 28 have been installed at previous stations in the assembly plant.
Moreover, since the fastener retention tabs 68 on the retainer clip 58 are angled to extend in the aft direction (i.e., extending back toward the bezel 40 and away from the head of the fastener 24), they will flex around the fastener threads during assembly of the handle bezel 40 to the end gate 10, but will flex into the fastener threads to prevent removal of the handle bezel 40 if one attempts to remove it—thus effectively acting like barbs on a Christmas tree type of fastener. Unlike a Christmas tree type of fastener, though, the handle bezel 40 can be removed for service. One need only to unscrew the bottom fastener 24 to disengage it from the fastener retention tabs 68 on the retainer clip 58, and then pull on the handle bezel 40 to cause the integral tabs 46 to release from the tab slots 18.
Thus, while the handle bezel 40 can be assembled with only access to the outer surface 12, it cannot be removed without having access to the bottom fastener 24 on the inner surface 14. This ensures that the added security provided by the key cylinder 52 is not compromised.
Another step that may be included in the installation of the handle bezel 40 is to apply a double sided tape 72 (shown in
Even though a handle bezel and key cylinder for an end gate of a vehicle have been discussed herein, such a bezel with a retainer clip may also be employed for assembly of other bezels to other vehicle closures.
