Abstract: The present disclosure relates to a modular, scalable liquid management system. The disclosed system is modular in that it is assembled from a few primary components. The system is scalable because the primary components are adapted to be re-sized and combined to form a system as wide, deep, and/or long as needed. In various exemplary embodiments, the system is assembled from a plurality of base components and arm components that are tightly connected to form the liquid management system. To resist shifting or separation of system components, the liquid management system is firmly anchored to the ground at multiple locations throughout the system.

Abstract: A releasable hinge for attaching tonneau covers to the cargo compartment of pickup trucks. The hinge has a hinge mechanism fastened to the bottom or underside of the tonneau cover. A complementary locking tab is mounted to the cab end of the cargo compartment. The hinge mechanism has a plate with a locking tongue that is received in a locking channel in the locking tab to latch the tonneau cover to the cargo compartment. To remove the tonneau cover from the cargo compartment, the tonneau cover is raised above a predetermined angle which disengages the locking tongue from the locking channel. This allows the hinge to separate from the locking tab. Any gas struts are released from their mounting brackets and the tonneau cover can be removed from the cargo compartment.

A pair of self-adjusting devices interconnect the two side rails and the rear rail. Each self-adjusting device includes a stop coupled to a side rail, a biasing device disposed between the stop and a corner piece, and an interconnecting plate fixedly coupled to the side rail and slidably coupled to the corner piece for accommodating relative movement therebetween. According to one aspect of the present invention, the interconnecting plate is coupled to the stop. According to another aspect of the present invention, the biasing device is a coil spring. According to still another aspect of the present invention, the interconnecting plate includes a slot for accommodating sliding movement of a fastener passing through the interconnecting plate and coupling the interconnecting plate to the corner piece.

Abstract: A tonneau cover assembly is provided including a front rail, a rear rail, and two side rails. The rear rail and two side rails include a pair of opposed lips defining a channel therein. The channel slidably receives a plurality of snap receptacles for cooperating with mating snaps of a tonneau cover having a snap-type mechanism. The channel also receives a hook-type retention member and retains it therein so that a tonneau cover having a hook-type fastening mechanism can be secured thereto. Accordingly, a single rail network can be used with either a snap-type tonneau cover fastening mechanism or a hook-type tonneau cover fastening mechanism.

Abstract: Improved corner strength and water tightness are provided in a bedliner having a bottom wall that is foldable from an as-molded position to a use position along a junction line that is spaced inwardly from the side walls and the wheel well covers to avoid joints and gaps in the bedliner corners or the interface between the wheel well covers and the adjacent bedliner components. Cut-away sections in the front wall of the bedliner are spaced inward from the bedliner corners and are to be removed to convert the bedliner from the as-molded position to the use position. The resulting segments of the front wall can be connected by a joint connector to improve strength and water tightness of the front wall.

Abstract: A cover assembly for the cargo area of a vehicle includes a plurality of rails which can be attached to the walls of a truck bed and a cover having an edge which is engageable by the rails. The rails are connected together by corner members. The corner members include a locking structure which is inserted into a channel in the rails. The locking mechanism of the corner members engages slots in the rails and secures the rails together. The rails include different structures which engage fasteners on the edges of the cover.

Abstract: A thermoformed thermoplastic truck bedliner has a front wall which is integral with and upstanding from a bottom wall. Side walls extend on either side of the front wall and also extend upwardly from the bottom wall. Relieved upwardly extending slots are cut in the bedliner between portions of the side walls and the front wall, to allow the upper portions of the side walls to fold or bend outwardly away from the front wall, thereby permitting improved nestability in a stack of like bedliners. The slots may be cut down to about the level of the wheel well covers, and may be formed in the front wall alone, or in the side walls. Inwardly extending portions of the side walls may be molded with outwardly extending portions of the side walls, such that when the slot is cut, the two portions of the side wall may be folded toward one another to overlap the portions and fully shield the truck bed. Similar structure may be formed in the front wall, and the bedliners may be of the under the rail, or over the rail type.

Abstract: A thermoformed thermoplastic truck bedliner has at least one pair of under-cut load restraint pockets formed by portions of opposed bedliner sidewalls. The pockets are recessed from the sidewall so that a load restraining member such as a 2.times.4 beam may be pressed downwardly to be snapped into engagement with the pockets. The pockets support the boards in a horizontal orientation, with the wide dimension of the board extending from front to back within the liner to give greater board stiffness against loads shifting from front to back. The pockets may be formed in either under the rail bedliners or in over the rail bedliners. In an alternative embodiment, each under-cut pocket is formed in a cross shape such that a board may be positioned horizontally or vertically.

Abstract: A thermoformed thermoplastic truck bedliner has a bottom wall with parallel front-to-back ribs which overlies the floor of a truck cargo bed. Two side walls extend upwardly on opposite sides of the bottom wall and are joined at a front wall. Ribs of a normal height define the load support surface of the bedliner bottom wall, while regions of parallel ribs which are lower in height than the normal ribs define cargo containment regions. The intersection of the reduced height ribs with the normal height ribs defines ridges which restrain escape of cargo in the front-to-back direction, while the bedliner side walls and elevated height protrusions on normal height ribs adjacent to the cargo containment regions restrain side-to-side displacement of the cargo.

Abstract: A thermoformed thermoplastic bedliner has a ribbed bottom wall which overlies the floor of a truck cargo bed. Two side walls extend upwardly from the bottom wall. The ribs extend longitudinally along the bottom wall and terminate at a transverse flat portion. The bedliner can be modified to accommodate mounting of a fifth wheel hitch to the truck frame, either by bolting through the bedliner or by cutting away the transverse flat portion.

Abstract: A truck cargo bed utility box blow molded of high density polyethylene which complements the styling of many truck bedliners. The utility box incorporates a mounting system for a central pneumatic spring which holds the lid of the box open. The mounting system consists of a bracket mounted to a wall forming part of the storage bin and a bracket on the bin lid. The lid bracket and the bin bracket extend to and engage with a hinge pin which joins the lid to the storage bin. The brackets are constructed of sheet metal and are mechanically joined by the hinge pin. The loads imposed on the lid and bin wall by the air spring are distributed through the hinge pin. The bin bracket is also attached to a metal rim which surrounds the opening into the box to provide load distribution. The metal rim provides a distortion resistant structure to which locking hasps can reliably latch. By distributing the loads imposed on the plastic lid and plastic bin distortion of the plastic is prevented.
