Description

FIELD

The present disclosure relates to accessories for motor vehicles such as running boards, roof rack components and spoilers used with motor vehicles, and more particularly to an accessory component for a motor vehicle which has a modular light assembly that can be quickly and easily installed in the accessory component to provide a degree of lighting to areas which are adjacent the vehicle.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Lighted vehicle accessory components are becoming increasingly popular with manufacturers of passenger cars and trucks. Such accessory components typically include lighted step rails used on minivans, vans, pickup trucks, SUVs and crossovers, as well other types of vehicles. Such lighting is often used to temporarily illuminate certain areas adjacent to the vehicle, for example the ground near the rocker panels of a passenger car, truck, SUV or van, to aid the vehicle operator in entering or exiting the vehicle, or to make the vehicle itself more visually conspicuous to other motorists during use of the vehicle. A popular present day use for such lighting is in connection with step rails used on passenger cars, trucks, SUVs, minivans, full size vans, and crossovers.

When incorporating lights into an external component of an accessory component of a motor vehicle, the complexity of assembly, cost and reliability become important considerations. Lights used on motor vehicle accessory components are exposed to the elements and therefore must be able to function reliably in conditions involving rain, snow and mud, as well as extreme hot and cold temperatures. This poses a challenge for designers to construct the accessory component so that the lighting elements and associated electrical wiring used to provide power to the lighting elements is integrated in such a way as to be protected from the elements.

Typically, present day lighting systems involve individual lights that are mounted to, or partially within, the accessory component. Such construction, while possibly providing adequate protection against the elements, can significantly complicate the assembly of the accessory component and/or its attachment to the vehicle during assembly of the vehicle. Attaching lights one by one, along with a wiring harness, to the accessory component such as by adhesives, mechanical fasteners or other means also requires a certain degree of skill, care and experience by the individual performing the installation. Such types of assembly can be challenging to perform when the installation of individual lighting components and associated electrical wiring needs to be done on a traditional vehicle assembly line. Individual lights that are not properly lined up with associated holes or openings in the accessory component during assembly can present areas where excessive water can enter an interior area of the accessory component and potentially compromise the operation of the lighting system. The requirement to have individual lights and associated wiring installed on the accessory component can also add to the overall cost of manufacture of the accessory component and/or the costs associated with installing it on a vehicle.

DETAILED DESCRIPTION

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

Referring to FIG. 1, there is shown accessory component assembly 10 for use on a motor vehicle 12. In this example the accessory component 10 assembly is a step rail and the motor vehicle 12 is a pickup truck. Merely for convenience, the following discussion will reference the accessory component assembly as “step rail 10”. In this example the step rail 10 provides a small degree of supplemental lighting 14 to areas adjacent the vehicle 12, and more specifically on the ground near the vehicle doors.

It will be appreciated immediately that the present teachings could be employed in connection with a wide variety of other forms of accessory components, for example and without limitation, side rails of roof rack systems, article supporting cross bars of roof rack systems, spoilers used on motor vehicles, and possibly even on front air dams, door mounted side rear view mirrors, vehicle rocker panels, etc. The present teachings are also not limited to use with pickup trucks but may be employed in connection with virtually any type of vehicle including SUVs, crossovers, minivans, full size vans, sedans, etc. The present teachings may also find utility in connection with recreational vehicles, campers, ATVs, boats and other marine vessels, snowmobiles, heavy duty earth moving equipment, etc. The present teachings may find utility in connection with any type of vehicle where it is desirable to provide some supplemental lighting to better help illuminate the vehicle or specific areas around the vehicle.

Referring to FIG. 2, the step rail 10 is shown in greater detail in exploded form. The step rail 10 may include a structural member 16 that may a single extruded, roll formed, or stamped metallic part which has a track or C-shaped channel 18 formed on an undersurface 20 thereof. The structural member 16 may be secured to a frame portion of the motor vehicle 12 by a plurality of conventional, suitable brackets 17 and conventional threaded fasteners (not shown) which position the structural member below the lower edge of the door of the motor vehicle 12. The precise cross sectional shape and/or configuration of the structural member 16 is not critical as long as it has the channel 18 or some form of elongated opening on its undersurface 20. Preferably the channel 18 extends along a major portion or the entire length of the structural member 16. The structural member 16 may be made from aluminum or any other material, possibly even high strength plastic, which is sufficiently strong to be used as a step rail on a vehicle.

Referring to FIGS. 2 and 3, positioned within the channel 18 is a modular light assembly 22. The modular light assembly 22 may include a frame 24 having a pair of oppositely extending shoulders 26 of dimensions enabling the shoulders 26 to ride on ledges 28 of the channel 18. In this example, the engagement of the ledges 28 and the shoulders 26 enables the frame 24 to be slid into the channel 18 so that the modular light assembly 22 may be positioned at a desired position within the structural member 16.

Referring again to FIG. 2, the modular light assembly 22 may include a plurality of lights 30 spaced apart at predetermined positions by lengths of electrical cables 32. An additional length of electrical cable 34 is electrically coupled to a connector assembly 36 so that electrical power can be provided from the vehicle's electrical system to the lights 30 via the lengths of electrical cables 32. Electrical cables 32 and the electrical cable 34 cooperatively form a wiring harness that lies within the frame 24 when the modular light assembly 22 is assembled into the frame 24. The lights 30 may be wired in series or parallel, but preferably are wired in parallel.

The lights 30 are spaced apart so as to lay over associated openings or holes 38 in the frame 24 when the modular light assembly 22 is fully assembled. In this manner light from the lights 30 may project through the holes 38 and illuminate areas of a ground surface adjacent the rocker panel areas of the vehicle 12. Adhesives or other suitable fasteners may be used to hold the lights 30 directly over the holes 38.

Referring further to FIGS. 2 and 3, the step rail 10 may also include a pair of end caps 40 that close off the ends of the structural member 16 after the modular light assembly 22 is inserted into the channel 18. Optionally, one or more holes in the structural member 16 may be formed to permit an external electrical cable from the vehicle's 12 wiring harness to be coupled to the electrical cable 34 either within the interior area of the structural member 16, or otherwise at some other area outside of the structural member.

With further reference to FIG. 2, one or more sections of a rubber or like pad 48 may be secured to an upper surface 50 of the structural member 16 to provide a generally non-slip or reduced-slip surface which is comfortable to step on. The pad 48 may incorporate any suitable means for attachment to the structural member 16, but in this example a plurality of barbed, resilient plugs or tangs 52 are formed to project from a lower surface of the pad 48. The tangs 52 may be press fit into correspondingly positioned slots or openings 54 (FIG. 3) in the structural member 16, after which they are essentially non-removable or removable only by applying a high degree of force to the pad 48 to pull the tangs 52 from the openings 54.

FIG. 4 shows a cross bar 100 of a vehicle roof rack (i.e., vehicle article carrier) system employing the modular light assembly 22 in a complementary shaped, downwardly opening, C-shaped channel 102. The cross bar 100 is typically employed to support articles thereon above a roof surface of the vehicle on which it is employed. Usually the cross bar 100 will be supported on a pair of support rails so as to extend perpendicularly above the vehicle roof between the support rails. If the cross bar 100 is formed with a slight curvature over its length, then the frame 24 of the modular light assembly 22 will typically require a corresponding curvature so that it can be inserted into the channel 102 without undue stress on the frame 24. Thus, the teachings herein may be used to allow a small degree of lighting 104 to be directed at the vehicle roof, which may provide an aesthetically pleasing appearance at night time as well as enhance visibility of the vehicle to other motorists during night time driving.

FIG. 5 shows one example of a support rail 200 incorporating the modular light assembly 22 in a downwardly opening, C-shaped channel 202 of the support rail 200. The support rail 200 may form part of a roof rack of a vehicle, and typically is attached to a roof surface of the vehicle to extend longitudinally along a major length of the roof surface. Again, if the support rail 200 is formed with a slight curvature over its length, then the frame 24 is preferably formed with a like curvature to enable easy insertion into the channel 202. This enables light 204 to be applied along side areas of the vehicle roof over which the support rail 200 is mounted.

FIG. 6 shows a spoiler 300 having a downwardly opening, C-shaped channel 302 formed therein in which the frame 24 of the modular light assembly is inserted. This allows light 304 to be provided to an area adjacent the rear bumper area of the vehicle.

FIG. 7 shows a front air dam 400 for a vehicle having a rearwardly opening, C-shaped channel 402 in which the frame 24 of the modular light assembly 22 is positioned. This enables light 404 to be provided to a ground area under the front end of the vehicle.

While the foregoing embodiments have illustrated the modular light assembly 22 being slidably insertable into a correspondingly shaped channel, it is also possible that the modular light assembly may be fit into an elongated recess of the accessory component (e.g., step rail) and held therein by a flexible lip associated with the frame 24 which engages an inwardly projecting lip of the elongated recess. Another means of attachment may be through the use of conventional, external barbed or Christmas-like fasteners that engage within small holes in the structural member 16 of the step rail 10 once the modular light assembly 22 is fully inserted into the elongated recess. And while one long modular light assembly 22 is shown in FIGS. 2 and 3, it will be appreciated that a series of shorter, independent modular light assemblies could be used and interconnected by suitable electrical cabling and connectors. Such an embodiment may be desirable where the modular light assembly would need to bend around a sharp corner (e.g., 90 degree bend), but where the designer still wishes to provide the appearance of a generally continuous light source. As such, one skilled in the art will appreciate that there are numerous ways that the modular light assembly 22 could be configured and secured to the structural member 16 or to other accessory components often used on a vehicle. Thus, the use of a C-shaped channel (i.e., channel 18) is merely one way that attachment can be effected.

The step rail 10 with its modular light assembly 22 provide a number of important advantages over previously constructed step rails that have typically employed individual lights which are individually attached to the structural member portion of the step rail. For one, using a modular construction for the modular light assembly 22 allows assembly to be performed in a controlled environment, and thus helps to ensure a high level of quality control over the manufacturing process. This can help to better ensure that no small openings are left during the manufacturing process which could allow excessive water to enter into the interior areas directly around the lights where they project through the openings in the structural member, and potentially compromise the operability of the lights. The modular light assembly approach described herein also allows assembly to be performed even more quickly and without special assembly skills or special tools. This can potentially reduce the cost of the overall step rail.

While various embodiments have been described, those skilled in the art will recognize modifications or variations which might be made without departing from the present disclosure. The examples illustrate the various embodiments and are not intended to limit the present disclosure. Therefore, the description and claims should be interpreted liberally with only such limitation as is necessary in view of the pertinent prior art.
