DETAILED DESCRIPTION
Reference is now made to FIGS. 1 and 2 illustrating a motor vehicle 10 including a bumper fascia 12 having a hitch opening 14. A hitch receiver 16 is carried in the hitch opening 14 in a recess 18 behind the bumper fascia 12.
A trailer hitch cover assembly 20 is displaceable between a deployed position wherein a flexible cover 22 of the trailer hitch cover assembly 20 closes the hitch opening 14 in the bumper fascia 12 and conceals the hitch receiver 16 (FIG. 1) and a retracted position wherein the hitch opening 14 is open and the hitch receiver 16 may be accessed through that opening (FIG. 2).
As best illustrated in FIGS. 3-5, the trailer hitch cover assembly 20 also includes a roller 24 carried for rotation with respect to a roller mount 26 on the bumper fascia 12. As should be appreciated, the flexible cover 22 is wound onto the roller 24 to expose and allow one to access the hitch receiver 16 and unwound from the roller to cover and conceal the hitch receiver.
As best illustrated in FIG. 5, the trailer hitch cover assembly 20 includes a guide track 28. In the illustrated embodiment, the guide track 28 comprises a first channel 30 and a second channel 32 carried on the bumper fascia 12 at opposite ends of the hitch opening 14. As illustrated the two channels 30, 32 are opposed to each other.
As also illustrated in FIG. 5, a flexible cover 22 includes a first margin 34 and a second margin 36. The first margin 34 is received and slides through the first channel 30 while the second margin 36 is received and slides through the second channel 32 as the cover 22 is displaced between the retracted and deployed positions.
In the illustrated embodiment of FIG. 5, the first margin 34 includes a first guide wire 38 and the second margin 36 includes a second guide wire 40. As should be appreciated, the first guide wire 38 is captured in the first channel 30 and the second guide wire 40 is captured in the second channel 32. Further, those channels 30, 32 are sized and shaped to allow free sliding movement of the margins 34, 36 and the guide wires 38, 40 through the channels while preventing any kinking of the guide wires. In this way, the flexible cover 22 is maintained in a stretched condition extending entirely across the width of the hitch opening 14 between the two channels 30, 32.
In the embodiment illustrated in FIGS. 3-5, the trailer hitch cover assembly 20 also includes a spring 42 connected to the roller 24. The spring 42 functions to bias the cover 22 toward the deployed position wherein the cover closes the hitch opening 14 and conceals the hitch receiver (see FIG. 1).
In this embodiment, one opens the cover 22 to obtain access to the hitch receiver 16 by engaging the finger hold 44 on the front face of the cover and displacing the cover downward in the direction of action arrow A (see FIG. 4) until the latch mechanism 46 is engaged to hold the cover in the retracted position. That latch mechanism 46 comprises opposed lugs 48 on the cover 20 that engage in cooperating resilient sockets 50 mounted on the bumper fascia 12. The latch mechanism 46 provides sufficient force to hold the cover 22 in the open position against the biasing spring 42. When one wishes to again close the cover 22, one engages the finger hold 44 and pulls upwardly (note action arrow B in FIG. 3) with sufficient force to snap the lugs 48 out of the sockets 50. The spring 42 then biases and holds the cover 22 in the fully deployed position closing the hitch opening 14 and concealing the hitch receiver 16.
In an alternative embodiment illustrated in FIG. 6, the trailer hitch cover assembly 20 includes a drive motor 52 instead of the spring 42. The drive motor 52 drives the roller 24 in order to displace the flexible cover 22 between the retracted and deployed positions illustrated in FIGS. 1 and 2.
More specifically, the drive motor 52 is connected to a controller 54 that controls the operation of the drive motor. The controller 54 may comprise a computing device such as a dedicated microprocessor or an electronic control unit (ECU) operating in accordance with instructions provide by appropriate control software. Such a controller 54 may include one or more processors, one or more memories and one or more network interfaces that communicate with each other over a communication bus.
In the embodiment illustrated in FIG. 6, the controller 54 includes a human interface 56. That human interface 56 may take the form of a simple actuator switch. In an alternative embodiment, that human interface 56 may take the form of a touch screen display such as may be provided on the center console of the motor vehicle. In either embodiment, an operator may utilize the human interface 56 to retract or deploy the cover 22 thereby either opening the hitch opening 14 to have access to the hitch receiver 16 or closing the hitch opening to conceal the hitch receiver.
As should be appreciated, the trailer hitch cover assembly 20 is closely associated with a method of covering and concealing a hitch receiver 16 on a motor vehicle 10. That method includes the steps of: (a) winding the cover 22 onto a roller 24 to expose and allow one to access the hitch receiver 16 and (b) unwinding the cover from the roller to cover and conceal the hitch receiver. As noted above, in one possible embodiment, that method further includes biasing the cover 22 toward a closed or deployed position covering and concealing the hitch receiver 16 by means of a spring 42. In another possible embodiment that method includes driving the cover 22 between a retracted position and a deployed position by means of a drive motor 52.
The trailer hitch cover assembly 20 provides a number of benefits and advantages. Smooth and consistent operation is ensured by providing a flexible cover 22 that is wound onto and unwound from a roller 24 when displaced between retracted and deployed positions. Significantly, when retracted, the cover 22 is held within the recess 18 in the bumper fascia 12 where it is protected to some degree from the wind and the elements.
The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
