Description
Background of the Invention
The present invention relates generally to a vehicle modular rail system for a bed portion of a vehicle and, more particularly, to a vehicle modular rail system for supporting accessories on the bed of a pickup truck.
Accessories, such as tonneau covers, light bars, utility boxes, and the like, have been used in the past with pickup trucks. Such accessories are normally secured in place by fasteners which are oftentimes affixed through openings drilled into the truck bed side members. Those openings, however, have been found to be problematic since the areas surrounding the openings are susceptible to the formation of rust. Furthermore, if use of a particular accessory is no longer desired, the openings remain in the truck bed side members after the cover is discarded unless filled or otherwise repaired.
Accordingly, a need exists for a vehicle modular rail system for supporting pickup truck bed accessories without affixing any fasteners through openings in the truck bed side walls. Furthermore, a need exists for a single, versatile system which is capable of accommodating a number of different accessories, thereby allowing one or more desired accessories to be easily mounted onto a pickup truck bed.

End caps 128 are also provided for closing off the end portions of the base rail 122 and the fill rail 124.
The second rail assembly 130, which is substantially the same as the first rail assembly 120, is shown in FIG. 2 and includes a second base rail 132 having one or more openings (not shown) for threadedly receiving one or more bolts 132a or like fasteners. The bolts 132a, upon being threaded upward within their respective openings, act to clamp the base rail 132 to an extended portion 210b of the second side wall portion 210. Positioned intermediate the top surface 210a and the base rail 132 is a second, upper protective strip 132b. Positioned intermediate a lower surface (not shown) of the second side wall portion 210 and the bolts 132a is a second, lower support plate 132c.
The second rail assembly 130 further includes a second fill rail 134 which overlies the protective strip 132c and is positioned adjacent to the second base rail 132. One or more bolts 134a or like fasteners pass through openings 132d in the base rail 132 and threadedly engage within openings 134b in the fill rail 134 to connect the fill rail 134 with the base rail 132. Located above the second base rail 132 and the second fill rail 134 is a second cap rail 136. The cap rail 136 is connected to the fill rail 134 by one or more bolts 136a or like fasteners which pass through openings 134c in the fill rail 134 and threadedly engage within openings (not shown) in the cap rail 136. Alternatively, the cap rail 136 could be connected to either the base rail 132 alone or to both the fill rail 134 and the base rail 132. End caps 138 are additionally provided for closing off the end portions of the base rail 132 and the fill rail 134.
It is further contemplated that the rails 122, 124 and 126 of the first rail assembly, and the rails 132, 134 and 136 of the second rail assembly, could be interconnected by interlocking means (not shown) rather than by bolts. The interlocking means would comprise one or more projections on a first rail member which would engage and lock with a corresponding recess or opening in a second rail member to join the two rail members to one another. It is additionally contemplated that the rails of the two rail assemblies 120 and 130 could be welded to one another, or formed together as a single unit.
Referring now to FIGS. 5-8, each of the first and second fill rails 124 and 134 is preferably formed from an elongated member 125 having an elongated channel 125a located therein. The channel 125a defines an opening in the outer surface 125b of the elongated member 125 and receives a light strip 125c therein, as shown in FIG. 5, which is visible through the opening in the outer surface 125b. The light strip 125c is connected to the truck's 202 electrical system in a known manner for receiving electrical energy for purposes of illumination. The channel 125a may alternatively receive a decorative strip 140, as shown in FIG. 6; a mating support member 142a of a tie down member 142, as shown in FIGS. 7 and 8; and/or mating support members 144a of a light bar 144, as also shown in FIG. 8.

The rods 156b and 156c are capable of being received within corresponding openings 155 in the base rails 122 and 132 (only the opening 155 in base rail 132 is shown) for locking the frame 152 to the base rails 122 and 132. Consequently, upon rotation of the handle member 156a, the hatch frame 152 can be released to an unlocked position and moved to an "up" position, as shown in FIG. 10, or can be locked to the base rails 122 and 132 in a "down" position, as shown in FIG. 11. When the hatch frame 152 is in the "down" position, frame member 152b overlaps tailgate 206a to lock the same in position.
A multi-piece bed liner 160 is preferably provided within the truck bed 200 for protecting the bed 200 against damage caused by cargo stowed therein. As shown in FIG. 12, the multi-piece bed liner 160 comprises a front section 162, first and second side sections 166 and 164, respectively, and a floor section 168. The floor section 168 is preferably formed from a nonslip material, which may be a different material from that used for the front and side sections. End portions 162a and 162b of the front section 162, end portion 166a of the first side section 166, and end portion 164a of the second side section 164 are shown in FIG. 12 having substantially straight edges. While not shown in FIG. 12, the end portions 162a and 162b of the front section 162 are joined with the end portions 166a and 164a of the first and second side sections 166 and 164 via clamps, adhesive tape or other conventional securing means.
It is further contemplated that end portions 162a and 162b of the front section 162, and end portions 166a and 164a of the side sections 166 and 164 may be formed having a C-shape. For example, FIG. 13 shows end portions 166a and 162b having a C-shape. A metal clip 168 is also shown for joining the end portions 162a and 162b to one another to provide strength and rigidity to the corners. It is additionally contemplated that the sections 162, 164, 166 and 168 of the liner 160 may be formed having a shape which substantially resembles that of an actual truck bed, i.e., they include all of the curves and valleys of a truck bed. It is further contemplated that a single-piece bed liner (not shown) may be employed in place of the multi-piece bed liner 160.
As shown in FIG. 12, the front section 162 of the liner 160 includes an L-shaped base portion 162c, and the first and second side sections 166 and 164 likewise include L-shaped base portions 166b and 164b, respectively. The floor section 168, when positioned within the truck bed 200, overlies the base portions 162c, 166b and 164b and is joined thereto via tape or like securing means (not shown).
As shown in FIGS. 3 and 4, the multi-piece bed liner 160 is connected directly to the rail means 110 via bolts 165 or like fasteners which pass through the first and second side sections 166 and 164. Consequently, fasteners which must be affixed through openings drilled into the bed 200 are not necessary for securing the liner 160 to the truck bed 200.
Referring again to FIG. 1, flexible cover means 300 is positioned over the truck bed 200 to cover and protect the bed 200 from theft, vandalism and the environment. The flexible cover means 300 comprises a protective cover 301, also referred to herein as a tonneau cover, having a front edge 302, an end edge 304 and first and second side edges 306 and 308. The cover 301 is formed from waterproof cloth or like material.
Attachment means 309, shown best in FIG. 15, is provided for removably attaching the protective cover 301 to the rail means 110. The attachment means 309 includes a plurality of cover snap elements 310 fixedly attached to edges 304, 306 and 308 of the cover 301 (see also FIG. 1) for fastening with corresponding rail snap elements 312 fixedly positioned along the first and second cap rails 126 and 136, and hatch snap elements 314 (see FIG. 2) fixedly positioned about frame members 152a-152c. The cover snap elements 310, the rail snap elements 312 and the hatch snap elements 314 serve to attach the cover 301 to the first and second cap rails 126 and 136 and to the hatch assembly 150. Preferably, the cover elements 310 are female snap elements while the rail elements 312 and the hatch elements 314 are male snap elements. Both male and female snap elements are conventional and well-known in the art.
The attachment means 309 further comprises an interlocking rod or cord 302a, shown in FIG. 14, which is sewn or otherwise attached to the front edge 302 of the cover 301. The rod or cord 302a is received within a mating recess 112a of a front rail member 112 for connecting the front edge 302 of the cover 301 to the rail means 110. The front rail member 112 is formed from first and second rail members 112b and 112c which are connected to one another by one or more bolts 112d. Alternatively, the front rail member 112 could be formed from a single rail member (not shown). The first rail member 112b overlies the first and Second base rails 122 and 132 and the first and second fill rails 124 and 134. The front rail member 112 is bolted, welded or otherwise fastened to the first and second base rails 122 and 132.
For providing additional security for the bed 200, the attachment means 309 further comprises a plurality of cross bar members 322, shown in FIGS. 2 and 15. Each end 322a of the cross bar members 322 is provided with first and second locking pins 324 and 326, respectively, which are received within angled slots 328a of brackets 328. The brackets 328 are secured along the first and second cap rails 126 and 136 by bolts 328b.
Provided on the underside 301a of the cover 301 is a plurality of wrap-around securing elements 330, formed from waterproof cloth or the like. Each securing element 330 is sewn or otherwise fastened to the underside 301a of the cover 301 and positioned to wrap-around and lock with a corresponding cross bar member 322. First and second snap elements 330a and 330b are provided on the wrap-around elements 330 to secure each element 330 to its corresponding cross bar member 322. Thus, by manually fastening together the first and second snap elements 330a and 330b on each wrap-around element 330, the wrap-around elements 330, and hence the cover 301, are secured to the cross bar members 322. The cross bar members 322 are, in turn, locked into position when they are inserted into angled slots 328a and the hatch assembly 150 is positioned in its "down" position (see FIGS. 11 and 16). This results because the angled slots 328a, which receive the first and second locking pins 324 and 326 of the cross bar members 322, are sloped so that their entrances 328a' are positioned away from the hatch assembly 150, see FIG. 15.

FIG. 19-20, where like reference numerals indicate like elements, show attachment means 350 for securing the cover 301 to the rail means 110. The attachment means 350 is a further modified attachment means of the type shown in FIGS. 2 and 15. As shown in FIGS. 19 and 20, cap rail 126' includes a recess 352 capable of receiving a first elongated strip 354 having a plurality of first male rail snap elements 354a fixedly positioned along its length. The strip 354 is secured within the recess 352 by screws 354b or like fasteners. A plurality of female cover snap elements 356 are positioned along corresponding portions of the first and second side edges 306 and 308 of the cover 301. Each cover snap element 356 includes an elongated intermediate section 356a and a engaging base section 356b, as shown in FIG. 19.
A first translating locking strip 358 is likewise received within the recess 352. Spaced along the length of the locking strip 358 are a plurality of locking apertures 359 having a receiving portion 359a and a locking portion 359b. The strip 358 further includes a cam follower surface 360 which engages with a corner portion 152c' of frame member 152c.
When the hatch assembly 150 is in the "up" position, as shown in FIG. 21, the strip 358 is biased toward the hatch assembly 150 by a spring 362. The spring 362 is connected at a first end to a pin 364 fixedly connected to the first cap rail 126', as shown in FIG. 19, and is connected at its second end to a protruding securing element 358a on the strip 358. While the hatch assembly 150 is in the "up" position, the cover snap elements 356 may be fastened to or unfastened from the rail snap elements 354a through the receiving portions 359a of apertures 359. When the hatch assembly 150 is in the "down" position, the corner portion 152c' engages with the cam follower 360 and acts to overcome the spring force and push the strip 358 away from the hatch assembly 150 to its "locking" position, as shown in FIG. 22. When the strip 358 is in its "locking" position, the locking portions 359b of the apertures 359 engage with the elongated sections 356a of the cover snap elements 356 to lock the base sections 356b of the snap elements 356 in fastened engagement with corresponding rail snap elements 354a, thereby securing the cover 301 to the rail means 110.
The second cap rail (not shown) is formed in the same manner as cap rail 126'. Furthermore, it includes a second elongated strip and a second translating strip, which are constructed in essentially the same manner as strips 354 and 358 shown in FIG. 19.
The attachment means 350 preferably further includes permanent fasteners, such as screw fasteners or rivets (not shown), for lockingly connecting the cover 301 to members 152a, 152b, and 152c of the hatch assembly 150. Alternatively, male and female snap elements, such as shown in FIGS. 1 and 2, may be employed for connecting the cover 301 to the hatch assembly 150. The attachment means 350 also preferably includes an interlocking rod or cord 302a for connecting the front edge 302 of the cover 301 to the rail means 110. Cross bar members 322, or cables which extend across the truck bed 200 may additionally be provided for center support of the cover 301.
While spring 362 is shown in FIGS. 19, 21 and 22 as comprising a tension spring, it is further contemplated that a compression spring could alternatively be used in its stead.
It is further contemplated by the present invention, that a utility box 365 may overlie and be fixed to the rail means 110, as shown in FIG. 23. Portions of the cap rails 126 and 136 are removed so that the opposite end portions 365a and 365b of the utility box 365 may rest directly upon the base rails 122 and 132 and the fill rails 124 and 134. The utility box 365 is preferably secured to the base rails 122 and 132 via bolts or like fasteners through the inside of the box 365. It is further contemplated by the present invention that the utility box 365 may include an ice chest 365c positioned therein.
It is also contemplated by the present invention that a bulkhead 370 made from a net material or the like, shown in FIG. 1, may be pivotably connected to the first and second rail assemblies 120 and 130 by, for example, a pivot rod (not shown) extending between the two assemblies 120 and 130.
Having described the invention in detail and by reference to preferred embodiments thereof, it will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
