Adaptable pick up truck configuration

[0002] This application claims priority from Provisional Application Serial No. 60/075,827 filed Feb. 24, 1998.

[0003] This invention relates to a pick up truck having an adaptable configuration which alternately permits increased cargo space and increased passenger space.

[0004] It is well known in the prior art to provide a pick up truck having a cab portion for carrying passengers and a cargo box for carrying cargo. The cargo box typically includes wheel covers which decrease the available width of the cargo box at the lower portion of the box. It is also known in the prior art that wider loads may be carried in the cargo box by providing one or more planar members, such as boards, which assist in carrying a wider load above the wheel covers in the cargo box.

[0005] It is also known in the prior art to provide aligned holes or passages in both the cab portion and the cargo box for carrying a somewhat longer load on the floor of the truck. However, this arrangement has the shortcoming of requiring the load to be placed directly in the passenger compartment, so that increased capacity for messy loads, such as dirt or gravel, is not practical. In addition, these configurations are not well-adapted for carrying passengers when not in use for carrying cargo. Other passages or openings have been provided between cab portions and cargo boxes, however, these configurations are concerned with the passing through or seating of passengers and are not suited for carrying increased cargo loads.

[0006] It is also known in the prior art to provide a cargo box including a front wall adjacent the cab portion and a rear wall. The pick up truck configuration is adaptable for carrying a cargo load longer than the cargo box and at or above the wheel covers protruding into the cargo box. A box panel portion is pivotally connected to the front wall of the cargo box and is movable between a generally vertical position in which the front wall of the cargo box is closed and a generally horizontal position in which the box panel portion partially overlies and is supported by the wheel covers. The cargo box includes a cargo box opening when the box panel portion is in the generally horizontal position. A cab panel portion is pivotally mounted to the cab portion and is movable between a generally vertical closed condition and a generally horizontal open position. The cab portion has a cab opening when the cab panel portion is in the generally horizontal position and the cab opening is at least partially aligned with the cargo box opening. Thus the pick up truck configuration is adaptable to carry the cargo load longer than the cargo box through both the cab portion and the cargo box and also can carry a wider load at or above the wheel covers. However, this arrangement has the shortcomings of requiring two panels, one on the cab portion and one on the cargo box which must be reconfigured. In addition, the cab portion is not isolated from the outside ambient elements. Furthermore, loose loads such as gravel cannot be kept separate from the cab portion.

[0007] As the popularity of trucks increases, it has become desirable to provide trucks that have rearward extended cab portions suitable for carrying more than three passengers. However, this reduces the load carrying capacity of the cargo boxes.

[0008] The present invention provides alternatives and advantages over the prior art by providing an adaptable pick up truck configuration which allows for carrying increased loads over the traditional pick up configurations. These arrangements are particularly useful for better versatility and utility of pick up trucks with expanded rear seat passenger compartments and shorter cargo boxes. Advantageously, these pick up truck configurations can alternately be used for carrying both front and rear seat passengers while also being adaptable to carry longer cargo loads while, in certain embodiments, protecting the vehicle interior from damage or dirt from the cargo load. Also advantageously, the increased load carrying capabilities of the pick up truck do not interfere with the provision of a fully functional cab portion for carrying both front and rear seat passengers. Advantageously, the pick up truck is easily adaptable for carrying passengers or for carrying increased cargo loads. Also, the pick up truck can be used as a traditional pick up truck with full passenger capacity and traditional load carrying capacity, when desired. Advantageously, the reconfiguration of the truck for expanded load carrying capacity is easily accomplished, preferably without the use of any tools. Certain embodiments of the invention also include sealed separation of the passenger compartment from the increased cargo space and features for covering the cargo load and preventing the cab interior from being exposed to outside ambient conditions. This arrangement also advantageously allows the use of a shorter cargo box for easier parking and maneuvering, while providing a truck for carrying more than three passengers or expanded cargo loads.

[0037] Referring to FIGS. 1 and 2, a vehicle being a pick up truck 10 includes a cab portion 12 for normally carrying passengers and a cargo box 40 for carrying various types of cargo loads (not shown), for example such as wooden boards each having a length of six to ten feet or a multitude of other cargo loads. As best shown in FIG. 1, the truck 10 includes a front passenger seating area, generally indicated at 16, having one or more front seats for seating one to three passengers. As is becoming increasingly popular, the cab portion 12 also includes a rear extended cab portion 15 which preferably includes a rear seat 17 for seating an additional one to three passengers. The truck 10 includes features making it easily adaptable for carrying longer loads without lengthening the cargo box 40 for ease of parking and maneuvering, while also permitting the increased passenger capacity, as described further hereinafter.

[0038] The cargo box 40 generally includes four sides comprising a front divider panel portion 41, first and second side walls 50, 51 and a rear wall 53 mainly provided by a tailgate 54. The tailgate 54 is pivotally mounted at a lower tailgate edge 55 adjacent to the side walls 50, 51 for movement between a generally horizontal open condition and a generally vertical closed condition, as shown in FIGS. 1 and 2. The tailgate 54 also includes an upper tailgate edge 56. The cargo box 40 includes a lower floor portion 37 extending between the panel portion 41, and walls 50, 51, and 53. The cargo box 40 further includes upwardly extending wheel covers 39 which protrude into the cargo box 40 and decrease the width of the cargo box 40 at the floor portion 37.

[0039] Referring to FIG. 2, the rear extended cab portion 15 includes the rear seat 17, which is preferably shown as a single bench seat, but may also be one or more separate seats. The rear seat 17 includes an upper seat back 18 which is pivotally mounted at its lower edge and a seat bottom 19 which is pivotally mounted at its forward edge. The rear seat 17 is normally configured for seating one to three passengers in the rear seat 17 for maximum passenger carrying capacity. The rear seat 17 may also be reconfigured for maximum cargo load capacity, as described further hereinafter and as shown in FIG. 2.

[0040] As shown in FIG. 1, the divider panel portion 41 is normally oriented in a generally vertical position and preferably provides a single structural dividing wall between the cargo box 40 and the cab portion 12 and simultaneously serves as the front wall of the cargo box 40 and the rear wall of the cab portion 12. The panel portion 41 normally separates and closes the cab portion 12 and its passengers from the ambient surroundings outside. The panel portion 41 is hinged to the truck body 11 for pivoting about a lower panel edge 21 from a generally vertical closed condition to a generally horizontal open condition as shown in FIG. 2. For example, the panel portion 41 may be hingedly connected to the floor portion 37 of the cargo box 40 by suitable hinges 42. The panel portion 41 may be made of any suitable sturdy material, such as metal or composites and preferably is sealed to the body 11 of the truck 10 around its outer panel edges when in the generally vertical closed condition.

[0041] A glass rear window 20 is normally positioned above the panel portion 41 and vertically aligned therewith for further closing the cab portion 12 from the outside surroundings. As best shown in FIG. 2, the rear window 20 can advantageously be rolled downward into the panel portion 41 by various amounts for allowing air flow into the cab portion 12. Also advantageously, the rear window 20 can be completely dropped into the panel portion 41 such that the glass rear window 20 is protected when the pick up truck 10 is reconfigured to the maximum load carrying condition, as will now be described.

[0042] As shown in FIG. 2, the truck 10 can easily be reconfigured from the maximum passenger carrying capacity shown in FIG. 1 to the maximum cargo carrying capacity shown in FIG. 2, without the use of tools. Referring to FIG. 2, the rear window 20 is preferably first dropped or rolled down completely into the panel portion 41. Next, the rear seat bottom 19 is pivoted forward and upward about its forward edge to a generally vertical position. Then, the rear seat back 18 is pivoted forward and downward about its lower edge to a generally flat horizontal condition as shown in FIG. 2. The divider panel portion 41 may then be pivoted forward and downward to the generally horizontal open condition as indicated by the arrow in FIG. 2. When the panel portion 41 is in the open condition, an open passage 14 is formed between the cargo box 40 and the cab portion 12. Thus cargo loads of a longer length can be carried which extend from the cargo box 40 and into the extended rear cab portion 15 for maximum load carrying capacity.

[0043] FIGS. 3A and 3B shows an alternate embodiment of the pick up truck configuration of FIGS. 1 and 2 with additional features added. The truck 10 of FIGS. 3A and 3B has the same description using the same numerals for the portions previously described in FIGS. 1 and 2. However, the truck 10 as best shown in FIG. 3B additionally includes a sliding cargo liner portion 60 and side storage compartments 30, as will now be described.

[0044] Referring to FIG. 3B, the cargo box 40 includes side storage compartments 30 located on each side of the cargo box 40. The side storage compartments 40 each have an inner wall 31 which preferably covers the wheel covers 39 and also an outer wall 32 which preferably is provided by the outer body sheet metal 33. The side storage compartments 30 also each preferably include hinged cover doors 29 which preferably may be latched and locked for secure storage of smaller cargo items. Although the side storage compartments 30 are shown as top opening, it will be appreciated that many other configurations are possible, including inner and outer openings. Advantageously, the side storage compartments 30 eliminate the empty area between the main cargo box 40 and the sliding cargo liner portion 60 to prevent dirt and moisture from settling in the empty area, if left open.

[0045] The truck 10 also includes the cargo liner portion 60 which preferably includes a front liner wall 61 and opposite side liner walls 62, 63 which are connected by a liner floor portion 64. The liner portion 60 is preferably made of a light, yet sturdy material, such as a lightweight metal, plastics, or composites. The liner portion 60 is slidably mounted onto the cargo box 40 at the inner walls 31 forming the storage compartments 30. The liner portion 60 may be slidably mounted to the cargo box 40 in any suitable manner. For example as shown in FIG. 3A, the cargo box 40 may include an integrally molded channel portion 65 extending along the length of the inner walls 31 of the side storage compartments 30 and the liner portion 60 may include a T-shaped guide rail 66 on the outer surfaces of the side liner walls 62, 63 on which the cargo liner portion 60 slides back and forth within the channel portions 65. It will also be appreciated that numerous other sliding configurations are possible, such as exchanging the guide rail 66 and the channel portion 65, or including rollers or chains or cables.

[0046] The truck 10 can easily be reconfigured from the maximum passenger carrying capacity shown generally in FIG. 1 to the maximum cargo carrying capacity shown in FIGS. 3A and 3B, without the use of tools. Referring to FIG. 3B, the rear window 20 is rolled down completely into the panel portion 41. Next, the rear seat bottom 19 is pivoted forward and upward about its forward edge to a generally vertical position. Then, the rear seat back 18 is pivoted forward and downward about its lower edge to a generally flat horizontal condition as shown in FIG. 3B. The divider panel portion 41 may then be pivoted forward and downward to the generally horizontal open condition shown in FIG. 3B. When the panel portion 41 is in the open condition, an open passage 14 is formed between the cargo box 40 and the cab portion 12. Next, the cargo liner portion 60 can be slid forwardly into the extended rear cab portion 15 as a single unit. It will be appreciated that the front and side liner walls 61, 62, 63 and the liner floor portion 64 move as a single unit. Preferably, the cargo liner portion 60 is light enough such that it may be pulled or pushed manually forward, such as by handles (not shown). However, it will also be appreciated that power operation could be provided to move the cargo liner portion 60 in the forward and rearward directions.

[0047] It will be appreciated that in the maximum load carrying condition shown in FIG. 3B, the cargo liner portion 60 is not covered and a direct air passage is formed between the cab portion 12 and the cargo box 40, such that the cab portion 12 is partially open to the ambient outside surroundings when the truck 10 is reconfigured to the maximum load carrying condition. Advantageously, the sliding cargo liner portion 60 enables loose cargo loads, such as gravel, to be carried using the maximum extended cargo capacity, without damaging the interior of the cab portion 12.

[0048] FIGS. 4-7 show another alternate embodiment of the adaptable pick up truck configuration in which the cab portion 112 is advantageously protected from the outside ambient surroundings in the maximum load carrying condition, without the loss of any load carrying capacity over the configurations in FIGS. 1-3. Features having a similar description to those in FIGS. 1-3 are denoted by similar numerals plus 100. A vehicle being a pick up truck 110 includes a cab portion 112 for normally carrying passengers and a cargo box 140 for carrying various types of cargo loads, such as wood or gravel. The truck 110 includes a front passenger seating area (not shown) having one or more front seats. As shown in FIGS. 4 and 5, the cab portion 112 also includes a rear extended cab portion 115 which preferably includes a rear seat 117 for seating an additional one to three passengers. The truck 110 includes features making it easily adaptable for carrying longer loads without lengthening the overall cargo box 140 for ease of parking and maneuvering, while also permitting the increased passenger capacity, as described further hereinafter.

[0049] The cargo box 140 generally includes four sides comprising a front divider panel portion 141, first and second inner walls 131 and a rear wall 153 mainly provided by a tailgate 154. The tailgate 154 is pivotally mounted at a lower tailgate edge 155 adjacent to the side walls 150, 151 for movement between a generally horizontal open condition and a generally vertical closed condition. The tailgate 154 also includes an upper tailgate edge 156. The cargo box 140 includes a lower floor portion 137 extending between the panel portion 141, and walls 131, 153. The truck 110 further includes upwardly extending wheel covers (not shown) which protrude into the cargo box 140 and decrease the width of the cargo box 140 at the floor portion 137 to the depth of the inner walls 131.

[0050] As best shown in FIGS. 4 and 5, the rear extended cab portion 115 includes the rear seat 117, which is preferably shown as a single bench seat, but may also be one or more separate seats. As best shown in FIG. 6, the rear seat 117 includes an upper seat back 118 which is pivotally mounted at its lower edge and a seat bottom 119 which is pivotally mounted at its forward edge. The rear seat 117 may normally be configured for seating one to three passengers in the rear seat 117 for maximum passenger carrying capacity as shown in FIGS. 4 and 6. The rear seat 117 may also be reconfigured for maximum cargo load capacity, as described further hereinafter and as shown in FIGS. 5 and 6.

[0051] As shown in FIG. 4, the main divider panel portion 141 is normally oriented in a generally vertical position and preferably provides a single structural dividing wall between the cargo box 140 and the cab portion 112 and simultaneously serves as the front wall of the cargo box 140 and the rear wall of the cab portion 112. The panel portion 141 normally separates and closes the cab portion 112 and its passengers from the ambient surroundings outside. The panel portion 141 is hinged to the truck body 111 for pivoting about an upper panel edge 121 from a generally vertical closed condition shown in FIG. 4 to a generally horizontal open condition as shown in FIG. 5.

[0052] As best shown in FIGS. 5, 6 and 7, the panel portion 141 includes an ancillary panel portion 143 which is pivotally connected to the main panel portion 141. For example, a lower ancillary edge 144 of the ancillary panel portion 143 is pivotally connected to the lower panel edge 21 of the main panel portion 141. The panel portion 141 and the ancillary panel portion 143 cooperatively provide a protective cover when the truck 110 is reconfigured for the maximum load carrying capacity, as described further hereinafter. The panel portion 141 and ancillary panel portion 143 may be made of any suitable sturdy material, such as metal or composites.

[0053] A glass rear window 120 is normally positioned above the panel portion 141 and vertically aligned therewith for further closing the cab portion 112 from the outside surroundings. The rear window 120 in this configuration preferably cannot be dropped into the panel portion 141. As best shown in FIG. 7, a window support rail 145 supports the rear window 120 and divides the rear window 120 from the panel portion 141. Although not shown, it will be appreciated that the rear window 120 could be openable by having portions that slide back and forth along the window support rail 145. However, it will be appreciated that in this configuration, the rear window 120 somewhat limits the height of the maximum cargo load.

[0054] The cargo box 140 preferably includes side storage compartments 130 located on opposite sides of the cargo box 140. The side storage compartments 130 are formed by the inner walls 131 which preferably cover the wheel covers and also outer walls 132 which preferably are provided by the outer body sheet metal 133. The side storage compartments 130 also each preferably include upper hinged cover doors 129 which may be latched and locked for secure storage of smaller cargo items. Although the side storage compartments 130 are shown as top opening, it will be appreciated that many other configurations are possible, including inner and outer openings. Advantageously, the side storage compartments 130 eliminate the empty area between the main cargo box 140 and the sliding cargo liner portion 160 to prevent dirt and moisture from settling in that empty area, if left open.

[0055] The truck 110 also includes the cargo liner portion 160 which preferably includes a front liner wall 161 and opposite side liner walls 162, 163 which are connected by a liner floor portion 164. The liner portion 160 is preferably made of a light, yet sturdy material, such as a lightweight metal, plastics, or composites.

[0056] The truck 110 can easily be reconfigured from the maximum passenger carrying capacity shown in FIG. 4 to the maximum cargo carrying capacity shown in FIG. 5, without the use of tools. Referring to FIG. 6, the rear seat bottom 119 is pivoted forward and upward about its forward edge to a generally vertical position as indicated by arrow A. Then, the rear seat back 118 is pivoted forward and downward about its lower edge to a generally flat horizontal condition as indicated by arrow B. The main divider panel portion 141 together with the folded ancillary panel portion 143 may then be pivoted upward past the horizontal position as indicated by arrow C. When the panel portion 141 is in the open condition, an open passage 114 is formed between the cargo box 140 and the cab portion 112. Next, the cargo liner portion 160 can be slid forwardly into the extended rear cab portion 115 as a single unit as enabled by the panel portions 141, 143 being pivoted upward above the sliding cargo liner portion 160. It will be appreciated that the front and side liner walls 161, 162, 163 and the liner floor portion 164 move as a single unit. Preferably, the cargo liner portion 160 is light enough such that it may be pulled or pushed manually forward, such as by handles (not shown). However, it will also be appreciated that power operation could be provided to move the cargo liner portion 160 in the forward and rearward directions. It will be appreciated that the pivoting open of the panel portions 141, 143 may also be supported or assisted by an extendible or detachable strut portion 146, as shown in FIG. 6.

[0057] After the cargo liner portion 160 is pulled forward for maximum load carrying capacity, the panel portions 141, 143 can pivoted downwardly to lie atop the cargo liner portion 160 and supported by the upper liner edges 147 as indicated by arrow D. Finally, the ancillary panel portion 143 can be pivoted forwardly about its ancillary edge 144 as indicated by arrow E such that the ancillary portion 143 and the panel portion 141 are generally horizontally aligned. In this horizontally aligned condition, the main divider panel portion 141 and the ancillary panel portion 143 cooperatively cover and close the cargo liner portion 160 in the maximum load carrying condition. It will further be appreciated that the panel portion 141 alone can be used to cover and close the cargo liner portion 160 when the cargo liner portion 160 is pulled only partially forward.

[0058] It will be appreciated that in the maximum load carrying condition shown in FIG. 5, the cargo liner portion 160 is covered and closed by the panel portions 141, 143 such that there is no direct passage to the outside ambient surroundings formed between the cab portion 112 and the cargo box 140 when the truck 110 is reconfigured to the maximum load carrying condition. Advantageously, the sliding cargo liner portion 160 enables loose cargo loads, such as gravel, to be carried using the maximum extended cargo capacity, without damaging the interior of the cab portion 112 and without exposure to the outside elements.

[0059] It will further be appreciated that the panel portions 141, 143 in the horizontal position are sealable and latchable to the cargo liner portion 160 for security of the cab portion 112 and for sealed protection of the cab portion 112 from the outside ambient surroundings while advantageously permitting maximum cargo capacity. It will also be appreciated that in the maximum load carrying conditions, the upper surfaces 148 of the panel portions 141, 143 can also serve as a package shelf for storing additional cargo items atop the cargo liner portion 160.

[0060] FIGS. 8-10 show yet another alternate embodiment of the invention which has a description similar to that of FIGS. 4-7 and in which similar features are denoted by similar numerals with a prime added. The main difference is that the sliding cargo liner portion 160′ has a length which is shorter than the cargo box 140′. The cargo liner portion 160′ has side liner walls 162′, 163′ having a length approximately equal to or slightly longer than the rear extended cab portion 115′ of the truck 110′ into which the cargo liner portion 160′ is extended for maximum load carrying capacity. The shorter cargo liner 160′ still allows for the same maximum cargo load capacity, but is lighter than the full length cargo liner portion 160 of FIGS. 4-7.

[0061] The embodiment of FIGS. 8-10 operates similar to that of FIGS. 4-7. The truck 110′ can easily be reconfigured from the maximum passenger carrying capacity shown in FIG. 8 to the maximum cargo carrying capacity shown in FIG. 10, without the use of tools. Referring to FIGS. 8 and 9, the rear seat bottom 119′ is pivoted forward and upward about its forward edge to a generally vertical position. Then, the rear seat back 118′ is pivoted forward and downward about its lower edge to a generally flat horizontal. The main divider panel portion 141′ together with the folded ancillary panel portion 143′ may then be pivoted upward past the horizontal position (not shown). When the panel portion 141′ is in the open condition, an open passage 114′ is formed between the cargo box 140′ and the cab portion 112′. Next, the cargo liner portion 160′ can be slid forwardly into the extended rear cab portion 115′ as a single unit as enabled by the panel portions 141′, 143′ being pivoted upward above the sliding cargo liner portion 160′. It will be appreciated that the front and side liner walls 161′, 162′, 163′ and the liner floor portion 164′ move as a single unit. Preferably, the cargo liner portion 160′ is light enough such that it may be pulled or pushed manually forward, such as by handles (not shown). Preferably in this embodiment, the side liner walls 162′, 163′ and the liner floor portion 164′ have a length that is only slightly longer than the extended rear cab portion 115′, such that the cargo liner portion 160′ is as light as possible for easy manual movement. However, it will also be appreciated that power operation could be provided to move the cargo liner portion 160′ in the forward and rearward directions.

[0062] After the cargo liner portion 160′ is pulled forward for maximum load carrying capacity, the panel portions 141′, 143′ can be pivoted downwardly to lie atop the cargo liner portion 160′ and supported by the upper liner edges 147′ and the ancillary panel portion 143′ can be pivoted forwardly about its ancillary edge 144′ such that the ancillary portion 143′ and the panel portion 141′ are generally horizontally aligned. In this horizontally aligned condition shown in FIG. 10, the main divider panel portion 141′ and the ancillary panel portion 143′ cooperatively cover and close the cargo liner portion 160′ in the maximum load carrying condition. It will further be appreciated that the panel portion 141′ alone can be used to cover and close the cargo liner portion 160′ when the cargo liner portion 160′ is pulled only partially forward.

[0063] It will be appreciated that in the maximum load carrying condition shown in FIG. 10, the cargo liner portion 160′ is covered and closed by the panel portions 141′, 143′ such that there is no direct passage to the outside ambient surroundings formed between the cab portion 112′ and the cargo box 140′ when the truck 110′ is reconfigured to the maximum load carrying condition. Advantageously, the sliding cargo liner portion 160′ enables loose cargo loads, such as gravel, to be carried using the maximum extended cargo capacity, without damaging the interior of the cab portion 112′ and without exposure to the outside elements.

[0064] It will further be appreciated that the panel portions 141′, 143′ in the horizontal position are sealable and latchable to the cargo liner portion 160′ for security of the cab portion 112′ and for sealed protection of the cab portion 112′ from the outside ambient surroundings while advantageously permitting maximum cargo capacity.

The rear seat 217 may also be reconfigured for maximum cargo load capacity, as described further hereinafter and as shown in FIGS. 18 and 19.

[0074] As shown in FIG. 17, the divider panel portion 241 is normally oriented in a generally vertical position and preferably provides a single structural dividing wall between the cargo box 240 and the cab portion 212 and simultaneously serves as the front wall of the cargo box 240 and the rear wall of the cab portion 212. The panel portion 241 normally separates and closes the cab portion 212 and its passengers from the ambient surroundings outside. The panel portion 241 is hinged to the truck body 211 for pivoting about a lower panel edge 221 from a generally vertical closed condition shown in FIG. 17 to a generally horizontal open condition as shown in FIGS. 18 and 19. The panel portion 241 may be made of any suitable sturdy material, such as metal or composites and preferably is sealed to the body 211 of the truck 210 around its outer panel edges when in the generally vertical closed condition.

[0075] A glass rear window 220 is normally positioned above the panel portion 241 and vertically aligned therewith for further closing the cab portion 212 from the outside surroundings. As best shown in FIG. 28, the rear window 220 is hinged about its upper window edge 280 and can advantageously be pivoted upward and rearward to an open condition which allows for a taller cargo load to be carried. Also advantageously as shown in FIG. 19, the rear window 220 can be completely removed when the pick up truck 210 is reconfigured to the maximum load carrying condition, as will now be described.

[0076] The truck 210 also includes the cargo liner portion 260 which preferably includes a front liner wall 261 and opposite side liner walls 262, 263 which are connected by a liner floor portion 264. The liner portion 260 is preferably made of a light, yet sturdy material, such as a lightweight metal, plastics, or composites. The liner portion 260 is slidably mounted onto the cargo box 240 at the inner walls 231 of the storage compartments. The liner portion 260 may be slidably mounted to the cargo box 240 in any suitable manner. For example, the cargo box 240 may include an integrally molded channel portion (not shown) extending along the length of the inner walls 231 and the liner portion 260 may include a T-shaped guide rail (not shown) on the outer surfaces of the side liner walls 262, 263 on which the cargo liner portion 260 slides back and forth within the channel portions. It will also be appreciated that numerous other sliding configurations are possible, such as exchanging the guide rail and the channel portion, or including rollers or chains or cables.

[0077] The truck 210 can easily be reconfigured from the maximum passenger carrying capacity shown in FIG. 17 to the maximum cargo carrying capacity shown in FIGS. 18 and 19, without the use of tools. Referring to FIG. 18, the rear window 220 is preferably pivoted upwardly and rearwardly to a generally horizontal open position. The rear seat bottom 219 is pivoted forward and upward about its forward edge to a generally vertical position. Then, the rear seat back 218 is pivoted forward and downward about its lower edge to a generally flat horizontal condition as shown in FIGS. 18 and 19. The divider panel portion 241 may then be pivoted forward and downward to the generally horizontal open condition. When the panel portion 241 is in the open condition, an open passage 214 is formed between the cargo box 240 and the cab portion 122. Next, the cargo liner portion 260 can be slid forwardly into the extended rear cab portion 215 as a single unit. It will be appreciated that the front and side liner walls 261, 262, 263 and the liner floor portion 264 moves as a single unit.

However, it will also be appreciated that power operation could be provided to move the cargo liner portion 260 in the forward and rearward directions. Finally, if desired when carrying tall cargo loads, the rear window 220 may be completely removed from the vehicle.

[0078] It will be appreciated that in the maximum load carrying condition shown in FIGS. 18 and 19, the cargo liner portion 260 is not covered and a direct air passage is formed between the cab portion 212 and the cargo box 240, such that the cab portion 212 is partially open to the ambient outside surroundings when the truck 210 is reconfigured to the maximum load carrying condition. Advantageously, the sliding cargo liner portion 260 enables loose cargo loads, such as gravel, to be carried using the maximum extended cargo capacity, without damaging the interior of the cab portion 212.

[0079] It will be understood that a person skilled in the art may make modifications to the embodiment shown in FIGS. 17-19. For example, although the panel portion 241 preferably pivots forward and downward for storage atop the rear seat back 218 in the maximum cargo configuration, it will also be appreciated that the panel portion 241 could alternately pivot upward and forward and include an ancillary panel portion for covering the cargo liner portion 260, similar to the arrangement shown in FIGS. 5-7. With reference to FIG. 18, it will further be appreciated that the panel portion as indicated at 241′ could alternately be connected to the rear window 220, and be lifted and removed with the rear window 220. Although the truck 210 is shown as including a divider panel portion 241 that is separate from the cargo liner portion 260, it will be appreciated that the panel portion 241 could be eliminated and the front liner wall 261 will also serve as the divider panel portion 241. In this case, the front liner wall 261 simply moves with the cargo liner portion 260 to the maximum cargo condition, thus eliminating any manipulation of a separate panel portion 241.

[0080] FIG. 20 shows yet another embodiment of the arrangement of FIGS. 17-19, with similar features denoted by similar numerals, plus a prime. The main difference in the embodiment of FIG. 20 is that the upper window edge 280′ of the rear window 220′ is hingedly connected to the truck body 211′ for pivotal movement upward and forward into the cab portion 212′ to the open condition. In addition, the panel portion 241′ is preferably connected to the lower window edge 281′ of the rear window 220′ and preferably contains suitable latching features for securing the panel portion 241′ and the rear window 220′ to the roof of the truck 210′ for storage when the truck 210′ is reconfigured to the maximum load carrying condition.

[0081] Yet another alternate embodiment of the invention is shown in FIGS. 21-23 and includes a pick up configuration in which the cargo capacity is extended in a rearward direction, instead of the forward direction in the prior embodiments. Referring to FIG. 21, a vehicle being a pick up truck 310 includes a cab portion 312 for normally carrying passengers and a cargo box 340 for carrying various types of cargo loads (not shown), for example such as wooden boards each having a length of six to ten feet or a multitude of other cargo loads.
