BACKGROUND OF THE INVENTION
1. Field of the Invention
The present application generally relates to a cargo tailgate enclosure for a pickup truck.
2. Description of the Related Art
Pick-up trucks are extremely popular. One of their primary advantages is the ability to haul loads in the storage bed located behind the cab of the vehicle. Unfortunately, often the storage bed is of an undesirable configuration for the load being transported. In particular, it is not unusual for the load to be larger than the truck bed, so that the tailgate of the truck needs to be lowered to enable the load to be adequately transferred. Unfortunately, this raises the risk that the load will fall out of the back of the truck, or that the load will need to be tied down, taking additional time.
For this reason, various truck tailgate enclosures have been developed. Despite the great success and excellent functionality of previous tailgate enclosures, new areas exist in which to further improve the cargo tailgate enclosure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Vehicle Tailgate Enclosure
With reference to FIGS. 1-7 one embodiment of vehicle tailgate enclosure 2 is illustrated. The tailgate enclosure 2 can be configured to coupled to a bed of a vehicle such as a pick up truck having a first side wall, a second side wall, a cargo floor, and a tailgate. In some embodiments, the tailgate enclosure 2 can be rotatably coupled to a vehicle bed and define a first position in which the tailgate enclosure is positioned substantially over the tailgate in an open position such that the tailgate enclosure defines an extended cargo area. The tailgate enclosure 2 can define a second position in which the tailgate enclosure is positioned substantially over the cargo floor to define a partitioned cargo area. FIG. 1 illustrates a perspective view of the vehicle tailgate enclosure 2. In the illustrated embodiment, the tailgate enclosure 2 comprises a first side panel 10, a second side panel 20, and a center panel 30 extending between the first side panel 10 and second side panel 20.
Side Panels
With reference to FIG. 1, in the illustrated embodiment, the first and second side panels 10, 20 each comprise an endcap 12, 22, and a plurality of beams 14, 24. In some embodiment, the endcaps 12, 22 can be configured to couple directly to sidewalls of the vehicle bed. In other embodiments, the endcaps 12, 22 can be configured to couple to a latch positioned on the sidewalls of the vehicle bed. In various embodiments, the coupling between the endcaps 12, 22 and the vehicle bed can be rotatable, while in other embodiments, the coupling can be rotationally fixed.
With continued reference to FIG. 1, in the illustrated embodiments, each of the beams 14, 24 comprises a generally rectangular tubular member having rounded corners. In other embodiments, the beams 14, 24 can comprise other types of members such as generally cylindrical tubular members, square tubes, or members having oval-shaped cross-sections. Advantageously, squared tubes such as the illustrated beams 14, 24 can be relatively easily retained within a housing, as relatively flat side surfaces can be clamped by the housing. Also advantageously, it can be desirable to have rounded tubular members with rounded edges to facilitate gripping and movement of the tailgate enclosure by one of the beams 14, 24.
In some embodiments, the beams 14, 24 comprise a metallic material. Desirably, the beams 14, 24 can be formed of an aluminum composition such as aluminum or an aluminum alloy. Advantageously, aluminum materials can have relatively high strength and low weight characteristics. In other embodiments, the beams 14, 24 can comprise other metallic compositions or alloys, or non-metallic compositions, such as plastic or composite materials.
With reference to FIG. 1, in the illustrated embodiment, the first and second side panels 10, 20 each comprise three beams 14, 24. Desirably, these beams 14, 24 are sized and spaced to span approximately a height of the sidewalls of a vehicle bed and to prevent passage of relatively large objects between the beams 14, 24, thus providing a substantial enclosure for an extended vehicle bed when the tailgate enclosure is in the first position. In other embodiments, the side panels 10, 20 of the tailgate enclosure 2 can each have more or fewer than three beams 14, 24, such as, for example two or four or more beams 14, 24.
With reference to FIG. 1, each of the beams 14, 24 can include a bed extending portion 16, 26 in which, when positioned in a vehicle bed, the bed extending portion 16, 26 is substantially parallel to the sidewalls of the bed. As illustrated, each of the beams 14, 24 can also include a bend portion 18, 28, and an enclosure portion 19, 29. In the illustrated embodiments, the bend portion 18, 28 comprises a radiused curve of approximately ninety degrees, although in other embodiments, other curve amounts and geometries are possible. The enclosure portion 19, 29 can extend from the curved portion 18, 29 to the center panel 30 of the tailgate enclosure 2.
Center Panel
With continued reference to FIG. 1, a center panel 30 extends between the first side panel 10 and the second side panel 20 of the tailgate enclosure 2. In the illustrated embodiment, the center panel 30 comprises two uprights 32 extending transversely to the beams 14, 24 of the side panels 10, 20. The uprights 32 each comprise stops 38 that can be composed of a rubber or polymeric material to cushion the tailgate enclosure 2 when it is rested on the cargo floor or tailgate of the vehicle bed. The center panel further comprises a plurality of beams 36 extending generally parallel to the enclosure portions 19, 29 of the beams 14, 24 of the side panels 10, 20.
In some embodiments, the center panel 30 can be formed of a material that is different from the material of the side panels 10, 20. For example, in some embodiments, as discussed in further detail below, the center panel 30 can be formed of a molded thermoplastic material. In other embodiments, the center panel 30 can be formed of a polymeric material, a composite material such as a carbon fiber composite or a glass fiber composite, or a metallic material. In some embodiments, desirably the use of a plastic material in the center panel 30 can reduce the total weight of a vehicle tailgate enclosure as compared to a similar tailgate enclosure that is comprised substantially entirely of metallic materials.
In some embodiments, the center panel 30 can be configured to be removably coupled to the side panels 10, 20. Advantageously, this removable coupling allows the tailgate enclosure 2 to be stored in a relatively small shipping box, thus facilitating distribution of a tailgate enclosure 2 in an unassembled state.
As discussed below, the center panel 30 can be configured to retain the side panels such that the assembly of the center panel 30 and side panels 10, 20 allows an adjustable width of the end caps 12, 22 of the side panels 10, 20 relative to one another. Thus, desirably one tailgate enclosure 2 can be adapted to fit vehicle beds having various different widths. In some embodiments, the tailgate enclosure 2 can have a width adjustment range (that is, the difference between a maximum width of the tailgate enclosure and a minimum width thereof) of approximately 2 inches, while in other embodiments, the width adjustment range can be approximately 4 inches and in still other embodiments, the width adjustment range can be approximately 6 inches.
With respect to FIGS. 2-4 and 6, various views of the tailgate enclosure 2 are illustrated. FIGS. 5 and 7 illustrate a cross sectional and exploded assembly view of the tailgate enclosure 2 showing the assembly of one embodiment of center panel 30. In the illustrated embodiment the center panel 30 comprises a first portion 40 and a second portion 50 coupled with fasteners 36. In the illustrated embodiment, the first and second portions 40, 50 are substantially identically configured, each comprising a portion of the uprights 32 and beams 38. When the portions 40, 50 are positioned in opposite orientations (that is, the first portion 40 is rotated 180 degrees with respect to the second portion), the first and second portions can be coupled with fasteners 36 such as screws. In other embodiments, other fastener types can be used to couple the first portion 40 to the second portion 50. In still other embodiments, the first and second portions 40, 50 can be configured with mating interference surfaces such that they snap together. As illustrated, the first portion defines a first lateral outer surface 44 of the center panel 30, and the second sidewall defines a second lateral outer surface 54 of the center panel 30. Advantageously, a center portion formed of two substantially identical portions 40, 50 can reduce manufacturing costs as a single tooling setup can be used to create both portions 40, 50. It can also advantageously reduce inventory costs as a single part can be maintained in inventory. It can also facilitate ease of assembly of the center panel 30.
With continued reference to FIGS. 5 and 7, coupling the first portion 40 to the second portion 50 forms the center panel 30. The center panel 30 comprises a plurality of recesses 42 each configured to receive a beam 14, 24 of the first and second side panels 10, 20. When the first and second portions 40, 50 are coupled, the beams 14, 24 are retained in the recesses 42. Width adjustment of the tailgate enclosure 2 can be provided by a depth, D, of the recesses 42. Accordingly, to adjust the width of the tailgate enclosure, the beams 14, 24 can be advanced varying amounts into the recesses 42 such that the end caps 12, 22 are a desired width apart, then retained at a desired width by securely coupling the first portion 40 to the second portion 50. In some embodiments, the center panel 30 can include a plurality of lock or set screws to retain the beams 14, 24 at a desired depth in the center panel 30.
Advantageously, in the illustrated embodiment, the two portion 40, 50 coupling of the center panel 30 provides a relatively rigid center panel 30 that resists twisting of one upright 32 relative to another, while having a low total parts count for a tailgate enclosure 2. In other embodiments, the center panel 30 can be formed of more than two portions, or can be formed of a single, unitary panel.
Center Panel Comprising Two Dissimilar Portions
With reference to FIGS. 8-14, another embodiment of tailgate enclosure 2′ is illustrated. The illustrated tailgate enclosure 2′ comprises first and second side panels 10, 20 substantially as described above with respect to FIGS. 1-7. Tailgate enclosure further comprises a center panel 30′.
FIGS. 12 and 14 illustrate a cross sectional and exploded assembly view of the tailgate enclosure 2′ showing the assembly of one embodiment of center panel 30′. In the illustrated embodiment the center panel 30′ comprises a first portion 40′ and a second portion 50′ coupled with fasteners 36. In the illustrated embodiment, the first and second portions 40′, 50′ are not substantially identically configured. Rather, the first portion 40′ defines an outer portion defining two lateral outer surfaces 44′. When the second portion 50′ is positioned within the lateral outer surfaces 44′, the first and second portions 40′, 50′ can be coupled with fasteners 36 such as screws. In the illustrated embodiment, the second portion 50′ can include holes for the fasteners, while the first portion 40′ has threaded inserts to receive the fasteners 36. Accordingly, in some embodiments, no fasteners or fastener holes are visible from one side of the tailgate enclosure 2′, thus presenting a sleek look in certain orientations. In other embodiments, other fastener types can be used to couple the first portion 40′ to the second portion 50′. In still other embodiments, the first and second portions 40′, 50′ can be configured with mating interference surfaces such that they snap together.
With continued reference to FIGS. 12 and 14, coupling the first portion 40′ to the second portion 50′ forms the center panel 30′. The center panel comprises a plurality of recesses 42′ each configured to receive a beam 14, 24 of the first and second side panels 10, 20. When the first and second portions 40′, 50′ are coupled, the beams 14, 24 are retained in the recesses 42′. In some embodiments, the center panel 30′ can include a plurality of lock or set screws to retain the beams 14, 24 in the center panel 30′.
Method of Assembly
Advantageously, vehicle tailgate enclosures 2, 2′ described herein can be easily transported in relatively small shipping packages such as boxes. Accordingly, shipping costs should be relatively low as compared to pre-assembled tailgate enclosures. Additionally, assembly can be relatively quick and easy to perform by an end-user, a distributor, or a retailer. Further savings can be obtained with the tailgate enclosures 2, 2′ described herein as the vehicle tailgate enclosures 2, 2′ can be adjustable in width, thereby reducing the need to maintain inventory of separate make and model specific vehicle tailgate enclosures.
For example, the vehicle tailgate enclosures 2, 2′ can be easily assembled using a method comprising assembling a center panel assembling a center panel 30, 30′ of the vehicle tailgate enclosure 2, 2′, advancing a plurality of beams 14 of a first side panel 10 into a corresponding plurality of recesses 42, 42′ in the center panel 30, advancing a plurality of beams 24 of a second side panel 20 into a corresponding plurality of recesses 42, 42′ in the center panel 30, 30′ and restraining the beams 14, 24 of the first side panel 10 and the second side panel 20 with respect to the center panel 30, 30′. Advantageously, in some embodiments, the entire assembly method can be performed with a single tool, used to couple the first portion 40, 40′ of the center panel 30, 30′ to the second portion 50, 50′ to form the housing 30, 30′.
