## Background
BACKGROUND
Field of the Invention
The present invention generally relates to a vehicle cargo bed structure and accessory. More specifically, the present invention relates to a vehicle cargo bed structure and accessory where the tailgate accessory covers a gap between the cargo bed and a tailgate.
Background Information
A vehicle such as a pick-up truck typically includes a cargo bed and a tailgate that pivotally moves between an upright closed position and an inclined open position. In order for the tailgate to move between the open position and the closed position, a pivoting end of the tailgate is slightly spaced apart from an adjacent end of the cargo bed. Consequently a gap is defined between the pivoting end of the tailgate and the adjacent end of the cargo bed. When the cargo bed is used to haul small material, such as gravel, stone or dirt, this small material can become lodged in the gap between the tailgate and the cargo bed.
SUMMARY
One object of the disclosure is to provide a vehicle cargo bed having a tailgate with a tailgate gap cover that is easily installed to the vehicle cargo bed and that can move between an upright position and a horizontal position with movement of the tailgate in order to cover a gap between the cargo bed and the tailgate.
In view of the state of the known technology, one aspect of the present disclosure is to provide a vehicle cargo bed structure having a vehicle cargo area that includes a bed floor, a first side cargo wall and a second side cargo wall, with a tailgate opening being defined at rearward ends of the first and second cargo walls. A tailgate has a first end pivotally attached to a rear of the vehicle cargo area for pivoting movement between a closed position covering the tailgate opening between the first side cargo wall and the second side cargo wall and an open position exposing the tailgate opening. A gap is defined between a rear end of the bed floor and the first end of the tailgate. A tailgate gap cover has a first attachment structure fixedly attached to the bed floor, a second attachment structure fixedly attached to the bed floor at a location spaced apart from the first attachment structure, and a biasing structure. The tailgate gap cover is pivotal between a horizontal orientation with the tailgate in the open position and an upright orientation with the tailgate in the closed position. The tailgate gap cover covers the gap with the tailgate in the open position. The biasing structure extends from the first attachment structure to the second attachment structure and biases the tailgate gap cover into contact with the tailgate in both the horizontal orientation and the upright orientation.

DETAILED DESCRIPTION OF EMBODIMENTS
Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to FIGS. 1 and 2, a vehicle 10 that includes a tailgate gap cover 12 (FIG. 2) is illustrated in accordance with a first embodiment. As is described in greater detail below, the tailgate gap cover 12 is an accessory that covers a gap G (FIGS. 3 and 4) defined between a cargo area 14 and a tailgate 16 of the vehicle 10.
Before describing the tailgate gap cover 12, a description of the cargo area 14 is provided with specific reference to FIGS. 2-4. The cargo area 14 basically includes a bed floor 20, a first side cargo wall 22 and a second side cargo wall 24, with a tailgate opening 26 being defined between rearward ends of the first cargo wall 22 and second cargo wall 24.
The bed floor 20 has a generally flat overall contour, except that a plurality of upwardly projecting ribs 20a are embossed or molded into the sheet metal that forms the bed floor 20 to provide greater rigidity and cargo-carrying strength to the bed floor 20. A plurality of recesses 20b is defined between each adjacent pair of the ribs 20a. Two utility tracks or accessory attachment tracks 30 are fastened to the bed floor 20. The accessory attachment tracks 30 extend in a direction parallel to a vehicle longitudinal direction D. Each accessory attachment track 30 is located between adjacent pairs of the ribs 20a within a corresponding one of the recesses 20b. One accessory attachment track 30 is located near but spaced apart from the first side cargo wall 22 and the other accessory attachment track 30 is located near but spaced apart from the second side cargo wall 24, as shown in FIG. 2. The first side cargo wall 22 and the second side cargo wall 24 can also optionally be fitted with additional accessory attachment tracks 30.
As shown in FIGS. 16 and 17, each of the accessory attachment tracks 30 has a U-shape in cross-section. The accessory attachment tracks 30 each have side walls 30a defining a channel 30b therebetween. Upper ends of the side walls 30a have opposing upper ends with lip portions that defining an elongated opening 30c. The lip portions include arcuate recesses 30d (FIG. 21) at spaced apart locations along the elongated opening 30c. As shown in FIG. 1, each of the accessory attachment tracks 30 can be concealed with a removable cover C that slides into the accessory attachment track 30, covering the elongated slot 30c (shown in an installed state in FIG. 2). The accessory attachment track 30 is a feature that is described in greater detail in, for example, U.S. Pat. No. 6,846,140 to Anderson et al., issued Jan. 25, 2005. U.S. Pat. No. 6,846,140 is incorporated herein by reference in its entirety.
The tailgate 16 has a first end 36, a second end 38, a first surface 40 and a second surface 42. The tailgate 16 has a lateral length L1 measured in a horizontal direction that is perpendicular to the vehicle longitudinal direction D. The first end 36 is pivotally attached to a rear of the cargo area 14 for pivoting movement between a closed position (FIGS. 1 and 3) covering the tailgate opening 26 and an open position (FIGS. 2 and 4) exposing the tailgate opening 26. In the closed position, the tailgate 16 is in a generally upright or vertical orientation with the first end 36 facing downward and the second end 38 facing upward. In the open position, the tailgate 16 is in a generally horizontal or inclined orientation with the first end 36 facing a rear end 44 of the cargo area 14 and the second end 38 facing rearward. The gap G is defined between the rear end 44 of the bed floor 20 and the first end 36 of the tailgate 16, in particular when the tailgate 16 is in the open position.
A description of the tailgate gap cover 12 is now provided with reference to FIGS. 3-21. The tailgate gap cover 12 basically includes a main portion 50, two hinge assemblies 52a and 52b, and a biasing member 54. In the first embodiment, the tailgate gap cover 12 is fastened to the accessory attachment track 30 proximate the rear end 44 of the cargo area 12 in a manner described in greater detail below. The tailgate gap cover 12 is configured to pivot between a horizontal orientation (FIG. 4) with the tailgate 16 in the open position and an upright orientation (FIG. 3) with the tailgate 16 in the closed position. In both positions, the tailgate gap cover 12 covers the gap G.
As shown in FIGS. 5 and 6, the main portion 50 of the tailgate gap cover 12 has a first planar portion 56, a second planar portion 58, a third planar portion 60 and a plurality of ribs 62. The first planar portion 56, the second planar portion 58 and the third planar portion 60 each have an overall length L2 (FIGS. 5 and 6) that is approximately equal to or slightly smaller than the lateral length L1 of the tailgate 16 (FIGS. 1 and 2). As shown in FIG. 5, the first planar portion 56 defines a first planar surface 56a, the second planar portion 58 defines a second planar surface 58a, and the third planar portion 60 defines a third planar surface 60a. 
The tailgate gap cover 12 also has a forward peripheral edge 64, a rearward peripheral edge 66, an upper surface 68a and an underside surface 68b. The upper surface 68a is typically exposed regardless of the orientation of the tailgate gap cover 12. The underside surface 68b faces the tailgate 16 and faces the bed floor 20 when the tailgate 16 is in the open position and when the tailgate gap cover 12 is in the horizontal orientation covering the gap G.
The ribs 62 are located along the underside surface 68b, as shown in FIG. 6. The ribs 62 are stiffening ribs that extend in a direction perpendicular to the length L2 of the main portion 50 from the first planar portion 56 to the third planar portion 60 along an underside of the main portion, as shown in FIG. 6. The first, second and third planar portions 56, 58 and 60 are made of metal with the ribs 62 welded to an underside thereof, as shown in FIG. 6. Further, the first, second and third planar portions 56, 58 and 60 can be made, for example, as a single metal plate that is bent slightly such that the first planar portion 56 is slightly angularly offset from the second planar portion 58 and the second planar portion 58 is slightly angularly offset from the third planar portion 60. The first, second and third planar surfaces 56a, 58a and 60a define a ramp or bridge shape as viewed from the side in FIG. 4 with the tailgate gap cover 12 in the horizontal orientation. The underside surface 68b can also be provided with a plurality of rubber or elastic polymer bumper members 72. The bumper members 72 project from the underside surface 68b of the tailgate gap cover 12 with a thickness ensuring contact with the tailgate 16. The bumper members 72 are dimensioned and formed to reduce or eliminate noise that might otherwise be generated via contact between the tailgate 16 and the tailgate gap cover 12.
It should be understood from the drawings and the description herein that the main portion 50 can alternatively be completely flat with the ribs 62 being omitted.
The forward peripheral edge 64 defines a cargo bed floor contacting portion and the rearward peripheral edge 66 defines a tailgate contacting edge portion. The forward peripheral edge 64 includes a plurality of projections 70. As shown in FIG. 7, the projections 70 are spaced apart from one another such that they align and extend into the recesses 20b of the bed floor 20 of the cargo area 14 with the tailgate gap cover 12 in the horizontal orientation.
A description of the hinge assemblies 52a and 52b is now provided with specific reference to FIGS. 5-6 and 8-21. The two hinge assemblies 52a and 52b are basically identical and have all of the same features, except that each connects to the spring member 54 in a different manner, as is explained in greater detail below.
Each of the hinge assemblies 52a and 52b shown in FIGS. 5-6, 8 and 10 includes a first bracket 80, a second bracket 82, a pivot pin 84 and a clamping bracket 86.
As shown in FIG. 5, the first bracket 80 is a square or rectangular shaped plate that attached to the underside surface 68b of the main portion 50 via, for example, a mechanical fastener F1. The first bracket 80 is connected to the second bracket 82 by the pivot pin 84 for pivoting movement about a pivot axis A1 defined by the pivot pin 84. Specifically, the first bracket 80 pivots relative to the second bracket 82 about pivot axis A1. Further, with the tailgate gap cover 12 attached to the accessory attachment tracks 30 in a manner described below, the tailgate gap cover 12 also pivots about the pivot axis A1. Hence, when the tailgate 16 is moved between the open position and the closed position, the tailgate gap cover 12 can pivot about the pivot axis A1 thereby moving with the tailgate 16 between the upright orientation and the horizontal orientation depicted in FIGS. 3 and 4.
As shown in FIGS. 10, 14 and 15, the first bracket 80 has a first end with a cylindrical portion 80a that receives the pivot pin 48 and a second end formed with a curved flange 80b. The curved flange 80b is shaped and configured to receive and retain a first end 54a of the biasing member 54.
The second bracket 82 is an elongated plate member that includes a pair of cylindrical portions 82a (defining a first end) and a main body 82b. The cylindrical portions 82a are dimensioned to receive the pivot pin 48 for pivoting movement about the pivot axis A1 and the pivot pin 84 relative to the first bracket 80. The main body 82b includes a first contoured portion 90, a second contoured portion 92, curved edges 94, a distal end 96 and a fastener receiving portion 98.
The first contoured portion 90 and the second contoured portion 92 of the second bracket 82 define aligned pocket portions that receive a second end 54b of the biasing member 54. More specifically, the second end 54b of the biasing member 54 is inserted into the second bracket 82 such that one side of the first end 54b is restrained by the first contoured portion 90 and another side of the first end 54b is restrained by the second contoured portion 92, as shown in FIG. 17. The second end 54b is inserted into first contoured portion 90 and the second contoured portion 92 from an area adjacent to the cylindrical portions 82a (a right side of FIG. 10.
During attachment of the hinge assemblies 52a and 52b to the main portion 50 of the tailgate gap cover 12, the first end 54a of the biasing member 54 is placed between the underside surface 68b of the main portion 50 and the curved flange portion 80b of the hinge assembly 52a, as shown in FIG. 6. Further, the second end 54b of the biasing member 54 is inserted between the first contoured portion 90 and the second contoured portion 92 of the second bracket 82 of the hinge assembly 52b, as is also shown in FIG. 6. The biasing member 54 is shown removed from the tailgate gap cover 12 in FIG. 11. The biasing member 54 is shaped and dimensioned such that when installed to the hinge assemblies 52a and 52b and the tailgate gap cover 12, the biasing member 54 acts as a torsion bar biasing the tailgate gap cover 12 into engagement with the tailgate 14, regardless of the position of the tailgate 14 (open position or closed position).
As shown in FIGS. 16 and 17, the curved edges 94 of the second bracket 82 of each of the hinge assemblies 52a and 52b extend over upper edges of the side walls 30a of the accessory attachment tracks 30. As shown in FIG. 16, the fastener F2 is installed through an aperture in the fastener receiving portion 98 of the second bracket 82 and into the clamping bracket 86 such that the clamping bracket 86 and the second bracket 82 are drawn toward one another clamping the hinge assemblies 52a and 52b to a corresponding one of the accessory attachment tracks 30.
As shown in FIG. 9, the clamping bracket 86 is a flat plate-like member that has upwardly extending edge portions or curved edges 100 and a centrally located fastener receiving portion 102. As is shown in FIGS. 16 and 17, the curved edges 100 engage downwardly projecting lips formed at the upper ends of the side walls 30a of the accessory attachment tracks 30 restricting movement of the hinge assemblies 52a and 52b. The fastener F2 extends into a threaded aperture in the fastener receiving portion 102 of the clamping bracket 86 serving to draw the clamping bracket 86 toward the second bracket 82 generating clamping force therebetween.
As shown in FIGS. 12, 13 and 21, the distal end 96 of the second bracket 82 includes lateral projections. With the hinge assemblies 52a and 52b installed to respective ones of the accessory attachment tracks 30, the lateral projections of the distal end 96 fit within the arcuate recesses 30d of the accessory attachment tracks 30, assisting in installing and locating the tailgate gap cover 12 in position relative to the accessory attachment tracks 30 and the bed floor 20 of the cargo area 14.
It should be understood from the drawings and the description herein that the hinge assemblies 52a and 52b basically define attachment structures of the tailgate gap cover 12. The clamping bracket 86 and second bracket 82 basically define first and second parts of that attachment structure.
Second Embodiment
Referring now to FIGS. 22-25, a tailgate gap cover 112 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 (′).
The tailgate gap cover 112 includes many of the features of the tailgate gap cover 12 of the first embodiment. Specifically, the tailgate gap cover 112 includes the main portion 50 and the biasing member 54 as described above with respect to the first embodiment. The main portion 50 of the tailgate gap cover 112 includes the first planar portion 56, the second planar portion 58, the third planar portion 60, the plurality of ribs 62, the forward peripheral edge 64 with the plurality of projections 70, the rearward peripheral edge 66 and the bumper members 72, as described above with respect to the first embodiment. Further, the biasing member 54 includes the first end 54a and the second end 54b, as described above with respect to the first embodiment.
However, in the second embodiment, the hinge assemblies 52a and 52b are replaced or modified such that the tailgate gap cover 112 installs directly to a bed floor 20′ of the cargo area 14 of the vehicle 10 shown in FIG. 24. The bed floor 20′ of the cargo area 14 is identical to the bed floor 20 described above with respect to the first embodiment, except that in the second embodiment, the accessory attachment tracks 30 are eliminated. In other words, there are no accessory attachment tracks 30 present on the bed floor 20′. Rather, in the second embodiment, hinge assemblies of the tailgate gap cover 112 are attached or fastened directly to the bed floor 20′ of the cargo area 14.
Specifically, the tailgate gap cover 112 basically includes a first hinge assembly 152a (a first attachment structure) and a second hinge assembly 152b (a second attachment structure) that are both fixed directly to the bed floor 20′ of the cargo area 14 via fasteners F2. The first hinge assembly 152a and the second hinge assembly 152b are basically identical and only differ in their connection to the biasing member 54. The first hinge assembly 152a and the second hinge assembly 152b have many of the features of the hinge assemblies 52a and 52b. For example, each of the first hinge assembly 152a and the second hinge assembly 152b includes the first bracket 80, including the cylindrical portion 80a and the curved flange 80b, as described above with respect to the first embodiment. The cylindrical portion 80a receives the pivot pin 84, and the curved flange 80b receives the first end 54a of the biasing member 54.
Each of the first hinge assembly 152a and the second hinge assembly 152b further includes a second bracket 182. The brackets 182 have many of the features of the brackets 82 of the first embodiment, such as the pair of cylindrical portion 82a that receive the pivot pin 84. The bracket 182 of each of the first hinge assembly 152a and the second hinge assembly 152b also includes the first contoured portion 90 and the second contoured portion 92 (as described above with respect to the first embodiment). The first contoured portion 90 and the second contoured portion 92 receive the second end 54b of the biasing member 54 thereby retraining movement of the second end 54b of the biasing member. Hence, in the second embodiment, the biasing member 54 serves as a torsion bar that biases movement of the tailgate gap cover 112 toward the horizontal orientation and into contact with the adjacent surface of the tailgate 16 with the tailgate 16 in both the open position and the closed position.
The brackets 182 also include a fastener receiving portion 198 with an aperture that receives the fastener F2. Hence, the brackets 182 have many of the features of the brackets 82 of the hinge assemblies 52a and 52b of the first embodiment. However, the fastener receiving portion 198 is shaped and configured to rest directly on the exposed surface of recesses 20b′ the bed floor 20′ of the cargo area 14.
Hence, the first hinge assembly 152a and the second hinge assembly 152b are structured such that the tailgate gap cover 112 is pivotal between a horizontal orientation with the tailgate 16 in the open position and an upright orientation with the tailgate 16 in the closed position. Further, as with the first embodiment, the tailgate gap cover 112 covers the gap G with the tailgate 16 in the open position. Further, as with the first embodiment, the biasing member 54 and the first hinge assembly 152a and the second hinge assembly 152b define a biasing structure that biases the tailgate gap cover 112 into contact with the tailgate 16 in both the horizontal orientation and the upright orientation.
The features of the vehicle 10 are conventional components that are well known in the art. Since features of the vehicle 10 other than the tailgate gap covers 12 and 112 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.
