[0028] Referring initially to FIG. 1, a vehicle 10 that includes a lighted vehicle cargo area arrangement with a lighting system 12 is illustrated in accordance with a first embodiment. The vehicle 10 includes a cargo area 14 having a floor 16, a front wall 18 and two side walls 20. The cargo area 14 also includes a tailgate (not shown). In the depicted embodiment, the vehicle 10 is a pickup truck and the cargo area 14 is the cargo bed of the pickup truck. However, it should be understood from the drawings and the description herein that the cargo area 14 and side walls 20 can be part of an enclosed cargo area of a van or enclosed truck structure.
[0029] The side walls 20 are symmetrical to one another but otherwise identical. Therefore, description of one applies equally to the other. As shown in FIG. 2, the side wall 20 has a wall structure that includes, for example, several sheet metal panels welded, riveted, fastened or otherwise rigidly fixed to one another to define the side wall 20. In the depicted arrangement, the panels that make up the wall structure of the side wall 20 provide one example of a wall structure that defines the side wall 20.
[0030] The side wall 20 includes at least an outboard panel 22, an inboard panel 24 and a top panel 26. However, the wall structure of the side wall 20 can include additional panels (not shown). The inboard panel 24 defines a first wall surface 28 that faces the cargo area 14. Specifically, the front wall 18 and each of the two side walls 20 at least partially surround and at least partially define the cargo area 14. The first wall surface 28 is an inboard facing surface of the side wall 20 directly facing the cargo area 14.
[0031] The first wall surface 28 of the side wall 20, as shown in FIG. 2, includes a plurality of a large concaved or recessed portions 32. In the depicted embodiment, there are two recessed portions 32.
[0032] An accessory attachment track 34 (a rail that is described in greater detail below) is mounted proximate an upper end of the side wall 20. Portions of the accessory attachment track 34 are fixed to the side wall 20 in a conventional manner, by, for example, mechanical fasteners. However, the accessory attachment track 34 is spaced apart from those areas of the first wall surface 28 that define the recessed portions 32. As shown in FIG. 4, a lamp receiving space 36 is defined laterally between an outboard surface 38 of the accessory attachment track 34 and the first wall surface 28 along the recessed portion 32 of the side wall 20. The lamp receiving space 36 is further defined beneath the top panel 26.
[0033] A description of a first embodiment of the lighting system 12 of the lighted vehicle cargo area arrangement is now provided with specific reference to FIGS. 2-10. As shown in FIGS. 2, 3 and 4, the lighting system 12 provides illumination to the floor 16 of the cargo area 14 and lower regions of the cargo area 14. In effect, the lighting system 12 provides indirect lighting to the cargo area 14 such that a person can see any objects located within the cargo area 14 in the dark, with a minimal amount of light shining outside the cargo area 14.
[0034] The lighting system 12 basically includes the accessory attachment track 34, a mounting bracket 40, a plurality of lamp assemblies 42 and a controller 44 (shown in FIG. 10 only).
[0035] The accessory attachment track 34 is an elongated metallic member or rail that includes an upper section 50, a lower section 52 and a flange 54. The upper section 50 and lower section 52 are spaced apart from one another such that a slot 56 is defined between the upper section 50 and the lower section 52. The flange 54 extends below the lower section 52 and includes the outboard surface 38, mentioned above. Various accessories can be attached and removed from the accessory attachment track 34, as described in, for example, U.S. Pat. No. 7,874,774, issued Jan. 25, 2011, and U.S. Pat. No. 7,175,377, issued Feb. 13, 2007. Both U.S. Pat. No. 7,874,774 and U.S. Pat. No. 7,175,377 are incorporated herein by reference in their entirety.
[0036] The accessory attachment track 34 (the rail) is attached to the side wall 20 by conventional means, such as mechanical fasteners and/or rivets. The accessory attachment track 34 can alternatively be welded to the side wall 20. The above described outboard surface 38 is defined on the flange 54 and at least partially defines the lamp receiving space 36. The flange 54 also includes a lower edge 56 (FIGS. 3 and 4) that extends the horizontal length of the accessory attachment track 54.
[0037] As shown in FIGS. 5 and 6, the mounting bracket 40 can be an elongated member. As indicated in FIG. 9, the mounting bracket 40 is attached to the flange 54 along the outboard surface 38 (a hidden surface of the accessory attachment track 34). The mounting bracket 40 includes a rail attachment section 60, an intermediate section 62 and a lamp attachment section 64. The rail attachment section 60 is a generally flat section of the mounting bracket 40 and is rigidly attached to the flange 54 of the accessory attachment track 34 (the rail). The rail attachment section 60 extends in a downward direction along the accessory attachment track 34 (the rail) with the mounting bracket 40 installed thereto. The rail attachment section 60 can include two apertures with, for example, two threaded nuts 60a that are welded or otherwise fixed to the rail attachment section 60 proximate to the apertures. A pair of fasteners F (FIG. 9) can be installed through corresponding apertures in the flange 54 to attach the mounting bracket 40 to the accessory attachment track 34 (the rail).
[0038] The intermediate section 62 of the mounting bracket 40 extends upwardly from a lower end of the rail attachment section 60 toward the lamp attachment section 64. The intermediate section 62 of the mounting bracket 40 also extends away from the lower edge 56 of the accessory attachment track 34 with the mounting bracket 40 installed thereto. The intermediate section 62 further curves upward and away from the lower edge 56 of the accessory attachment track 34, and further extends toward the first wall surface 28 (see FIG. 4) and toward the lamp attachment section 64. The intermediate section 62 is further shaped to ensure that the lamp attachment section 64 and the lamp assembly 42 are completely disposed within the lamp receiving space 36, above the lower edge 56 of the flange 54 of the accessory attachment track 34 (the rail). Hence, the mounting bracket 40 and the lamp assembly 42 are disposed above a bottom-most end of the accessory attachment track 34 (the rail).
[0039] In the depicted first embodiment, the rail attachment section 60, the intermediate section 62 and the lamp attachment section 64 are rigidly fixed to one another and unitarily formed as a single monolithic element. Further, as shown in FIGS. 7-9, the rail attachment section 60 and the lamp attachment section 64 are angularly offset from one another defining an acute angle α therebetween. The line L in FIG. 9 is parallel to the rail attachment section 60. Thus the angle α represents the angle between rail attachment section 60 and the lamp attachment section 64. The angle α is approximately 45 degrees, but can be anywhere in a range from 30 degrees to 60 degrees.
[0040] The lamp attachment section 64 can include an elongated opening 66, shown in FIGS. 5-8.
[0041] The lighting system 12 can include a plurality of the mounting brackets 40 and a corresponding plurality of the lamp assemblies 42. Each mounting bracket 40 is identical to the other mounting brackets 40. Similarly, all the lamp assemblies 42 are the same. Therefore, description of one applies to all.
[0042] In FIG. 10, two of the mounting brackets 40 are depicted along with two of the lamp assemblies 42. Each lamp assembly 42 includes a lamp housing 70, a lamp 72 and an attachment member 74. The lamp housing 70 includes a tube-shaped projection 70a that is insert-able through the elongated opening 66 of the corresponding lamp attachment section 64 of the mounting bracket 40. The lamp 72 is a LED (light emitting diode) but can alternatively be a halogen or other conventional light providing element. The attachment member 74 can then be attached to the projection 70a, thereby retaining the lamp assembly 42 to the mounting bracket 40. In the depicted embodiment, the lamp housing 70 is located at the outboard side of the mounting bracket 40 within the lamp receiving space 36, as shown in FIG. 4. The attachment member 74 is located on the inboard side of the mounting bracket 40.
[0043] The attachment member 74 can attach to the projection 70a in any of a variety of ways. For example, the attachment member 74 can include threads (not shown) that engage corresponding threads (not shown) on the projection 70a. Alternatively, the attachment member 74 can include snap fitting projections (not shown) that engage corresponding recesses (not shown) on the projection 70a. Still further, the attachment member 74 can include one or more gripping projections (not shown) that simplify tightening or loosening of the attachment member 72 by a user (e.g., the attachment member 74 can be configured as a wing-nut). In other words, the lamp housing 70 can be installed to the mounting bracket 40 in any of a variety of ways that allow the lamp housing 70 be positioned at any one of a plurality of locations along a horizontal length of the lamp attachment section 64 of the mounting bracket 40.
[0044] The angle α (FIG. 9) between the lamp attachment section 64 and the rail attachment section 60 of the mounting bracket 40 ensures that the lamp 72 within the lamp housing 70 is aimed to shine light beneath the mounting bracket 54 and accessory attachment track 34 (the rail) toward the vehicle cargo area 14 and more specifically along the floor 16 of the cargo area 14.
[0045] As shown in FIGS. 7, 8 and 10, each of the lamp housings 70 is connected to the controller 44 via a wiring harness 80. The controller 44 can include a simple switch that allows an operator to mechanically turn the lamps 72 on and off. Further, the controller 44 can be programmed to detect the state of an engine E within the vehicle 10. Specifically, the controller 44 can detect whether or not the engine E is in a running condition. In the event that lighting of a cargo area is not permitted, the controller 44 limits operation of the lamps 72 to situation where the engine E is not running. If the controller 44 subsequently detects that the engine E is in a running condition, the lamps 72 can be automatically turned off.
[0046] The controller 44 can further be configured to operate within a voltage range that is lower than the standard 12 volt electric power supplied within a vehicle. For example, where power is to be conserved, the controller 44 and the lamps 72 can be designed to run on a reduced voltage. A power converter 76 can be installed between a power source 78 and the controller 44 to step down the voltage from the power source 78.
[0047] As shown in FIGS. 7 and 8, the lamp assembly 42 can be positioned at any of a plurality of locations along the elongated opening 66 (the slot). When the vehicle operator moves the lamp assembly 42 to a different location along the length of the elongated opening 66, the wiring harness 80 moves with the lamp assembly 42. The wiring harness 80 is provided with a coiled section 80a that is wrapped around a spindle 84. The spindle 84 is a fixed rod that is rigidly attached or mounted at either end to the outboard surface of the rail attachment section 60 of the mounting bracket 40, as shown in FIGS. 7 and 8.
[0048] The coiled section 80a of the wiring harness 80 is formed in a manner similar to a conventional telephone cord in that it is biased to remain in a coiled state and is further biased to move toward the coiled orientation or retracted orientation depicted in FIG. 7. Upon movement of the lamp assembly 42 to the location depicted in FIG. 8, the coils of the coiled section 80a of the wiring harness 80 are easily stretched such that adjacent coils separate from one another into an extended orientation as shown in FIG. 8. However, the coiled section 80a of the wiring harness 80 is biased to return toward the retracted orientation depicted in FIG. 7.
[0049] Referring now to FIGS. 11 and 12, a lighting system 12' in accordance with a second embodiment will now be explained. In view of the similarity between the first and second embodiments, the parts of the second embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the second embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity. The parts of the second embodiment that differ from the parts of the first embodiment will be indicated with a single prime (').
[0050] In the second embodiment, the accessory attachment track 34 is unaltered. However, in the second embodiment, the mounting bracket 40 is replaced with a mounting bracket 40' that includes the rail attachment section 60 and the lamp attachment section 64, as described with respect to the first embodiment above. However, the mounting bracket 40' includes an intermediate section 62' that is cut into two sections, when compared to the intermediate section 62 of the first embodiment, with a hinge 100 connecting the two sections of the intermediate section 62'. Hence, the lamp attachment section 64 can pivot relative to the rail attachment section 60. Thus, the lamp housing 70 can be pivoted and aimed where desired.
[0051] Referring now to FIGS. 13 and 14, a lighting system 12'' in accordance with a third embodiment will now be explained. In view of the similarity between the first and third embodiments, the parts of the third embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the third embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity. The parts of the third embodiment that differ from the parts of the first embodiment will be indicated with a double prime ('').
[0052] In the third embodiment, the accessory attachment track 34 is unaltered. However, in the third embodiment, the mounting bracket 40 is replaced with a mounting bracket 40'' that includes the rail attachment section 60 and the lamp attachment section 64, as described with respect to the first embodiment above. However, the mounting bracket 40'' includes a plurality of intermediate sections, each one divided into a first part 62a and a second part 62b. Each of the first parts 62a includes a socket and each of the second parts 62b includes a ball. Hence, each first part 62a and corresponding second part 62b defines a swivel joint that allows the lamp attachment section 64 to freely pivot relative to the rail attachment section 60 in a variety of directions, limited only by the restrictions of the ball and socket of the swivel joint. Thus, the lamp housing 70 can be pivoted and swiveled about a center point defined between the first part 62 a and the second part 62b of the intermediate sections. Since such ball and socket swivel joints allow movement in a conventional manner, further description is omitted for the sake of brevity.
[0053] Referring now to FIG. 15, a lighting system 112 in accordance with a fourth embodiment will now be explained. In view of the similarity between the first and fourth embodiments, the parts of the fourth embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the fourth embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity.
[0054] In the first embodiment, each side wall 20 includes two of the lamp assemblies 42. However, for long bed cargo areas, it is possible to increase the number of lamp assemblies 42 included in the lighting system. In the fourth embodiment, the lighting system 112 includes three of the lamp assemblies 42 on each side wall 20.
[0055] Referring now to FIG. 16, a lighting system 212 in accordance with a fifth embodiment will now be explained. In view of the similarity between the first and fifth embodiments, the parts of the fifth embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the fifth embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity.
[0056] In the first embodiment, each side wall 20 includes two of the lamp assemblies 42. However, for an extra-long bed cargo area, it is possible to increase the number of lamp assemblies 42 included in the lighting system. In the fifth embodiment, the lighting system 212 includes four of the lamp assemblies 42 on each side wall 20.
[0057] The controller 44 preferably includes a microcomputer with a lamp operating control program that controls the lamp assemblies 42, as discussed below. The controller 44 can also include other conventional components such as an input interface circuit, an output interface circuit, and storage devices such as a ROM (Read Only Memory) device and a RAM (Random Access Memory) device. The microcomputer of the controller 44 is programmed to control the lamp assemblies 42. The internal RAM of the controller 44 stores statuses of operational flags and various control data. The internal ROM of the controller 44 stores the control commands for various operations. It will be apparent to those skilled in the art from this disclosure that the precise structure and algorithms for the controller 44 can be any combination of hardware and software that will carry out the functions of the present invention.
[0058] The various portions of the vehicle 10 and cargo area 14 other than the lighting system 12 are conventional components that are well known in the art. Since vehicles and cargo areas are well known in the art, these structures will not be discussed or illustrated in detail herein. Rather, it will be apparent to those skilled in the art from this disclosure that the components can be any type of structure and/or programming that can be used to carry out the present invention.
[0059] Referring now to FIGS. 17 and 18, a wiring harness 180 in accordance with a sixth embodiment will now be explained. In view of the similarity between the first and sixth embodiments, the parts of the sixth embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the sixth embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity.
[0060] In the sixth embodiment, the wiring harness 80 of the first embodiment is replaced with the wiring harness 180. Further, the spindle 84 of the first embodiment is replaced with a winding mechanism 184. As shown in FIGS. 17 and 18, the lamp assembly 42 can be positioned at any of the previously mentioned plurality of locations along the elongated opening 66. When the vehicle operator moves the lamp assembly 42 to a different location along the length of the elongated opening 66, a portion 180a of the wiring harness 180 moves with the lamp assembly 42. The winding mechanism 184 includes an internal reel (not shown) that is spring biased to urge the portion 180a of the wiring harness 180 back into the winding mechanism 184. The winding mechanism 184 is pivotally mounted to the outboard surface of the rail attachment section 60 of the mounting bracket 40, as shown in FIGS. 17 and 18. Specifically, the winding mechanism 184 can pivot about the axis A in response to movement of the lamp assembly 42.
[0061] Upon movement of the lamp assembly 42 to the location depicted in FIG. 18, the portion 180a of the wiring harness 180 is easily drawn out of the winding mechanism 184. Further, the portion 180a of the wiring harness 80 is drawn back into the winding mechanism 184 by the biasing of the reel (not shown) within the winding mechanism, as depicted in FIG. 17.
[0062] The winding mechanism 184 is a conventional device. Therefore, further description is omitted for the sake of brevity.
