The present invention relates to a pivotable bed cover closeout device for a cargo bed of a vehicle which is movable to desired positions.
Removable or stowable soft tonneau covers for pickup vehicles are known in the art. These tonneau covers provide a vehicle with access to the cargo bed when the cover is pulled/folded back or removed, or, provides protection from the elements with the tonneau cover on/deployed. Such tonneau covers are typically manually unlatched on both sides before being moved into the desired positions.
Currently, tonneau covers have a rail that must be mounted down each side of the pickup box to give the cover a place to attach and seal out the elements. Typically, the rails are aluminum and/or the cover is a fabric cover. These side rails also act as a locator, aligning the bows/top cover as it is installed and positioned and provide a way to tension the top cover. Having to install these rails leads to additional height on the vehicle, cost, a non-cohesive look, and addition weight/complexity in the top.
There are other tonneau systems that are labeled as “low profile” to help fight the height and non-cohesive look. However, these covers still use an additional rail to mount the cover to the pickup bed and gain fabric tension so the design is no different than a “conventional” tonneau cover, it is just a different geometry.
Therefore, there remains a need for a system that eliminates the need for side rails, that utilizes an add-on bracket and/or an integrated bed design as an attachment method, eliminates the need of an additional attachment to gain tonneau cover tension, and provides easy multiple position accessibility into the cargo bed.
A tonneau cover assembly incorporating a cable-type system or any other type of suitable system that tensions a top cover, providing tension along the side of the cover to seal the cover to a bedside of a vehicle. When cables are used, the cables running down either side of the cover solves many of the aforementioned issues. Using a cable running fore and aft on the pickup truck or sport utility (SUV) vehicle bedside eliminates the need for the side rails to both locate and tension the top cover. The cable tension works to seal out the elements and holds the tonneau cover and bows in place.
With a rear engagement feature according to an embodiment of the present invention, it is readily implementable both as an add on bracket or as an integrated feature in a pickup truck bed or SUV or adapted to any other vehicle type. A rear latching system holds the tonneau in the closed tension state keeping the tonneau secured and tight until the cover is opened by an operator.
Optionally, an integrated boot cover is also sewn into the top cover at the front so that when the tonneau cover is rolled up in the stowed position, the boot cover can wrap and protect the top cover.
Preferably, according to an embodiment of the present invention, pockets are provided to hold the ends of center management bows to set the height and eliminate aluminum rails and attachment features. When the top cover is fabric or other flexible material these pockets, e.g., made of acrylonitrile butadiene styrene (ABS) having predetermined suitable thickness, are preferably sewn to the underside surface of the cover.
The tonneau cover assembly is mounted at a predetermined location in sealing engagement with a tailgate and is pivotable between at least a closed position sealing off with the vehicle tailgate, and a partially open position folded rearward to gain access into the cargo bed. When in the partially open position the opening into the bed is limited to provide the predetermined desired amount of accessibility to the bed, e.g., creates about a 6 inch opening for access. This has significant benefits, including, security, ease of stowing and accessing items near the tailgate, eliminating the need to fully open the tailgate and/or move the entire cover to access the bed, quicker access to the bed, and expedient cargo holding, e.g., hauling longer items such as wood planks extending through the opening and into the cargo bed. Intermediate open position(s) is/are also contemplated.
The tonneau cover assembly is also movable between the closed position, partially open position, and a fully open position for full access to the cargo area, according to an embodiment of the present invention. Intermediate position(s) is/are also contemplated.
The tonneau cover assembly reduces weight and complexity, and eliminates the side rails when compared to current tonneau systems.
According to another embodiment of the present invention, at least one release lever of the rear latching system is mounted in a convenient location for easier access to pull the release lever generally toward the operator for releasing the latching mechanism, when desired. The release lever location(s) reduces or eliminates interference with the cover to operate. The cable system runs fore and aft, and additionally has cable tensioning along the front of the system.
Using a cable running fore and aft on the pickup truck or sport utility (SUV) vehicle bedside eliminates the need for the side rails to both locate and tension the top cover. The cable tension works to seal out the elements and holds the tonneau cover and bows in place.

The assembly 100 has a rear attachment assembly with a pivotal portion shown generally at 111 for moving between a closed position and a first open position to partially uncover the opening into the cargo area. The assembly 100 includes at least one rear attachment portion 102, at least one latch mechanism indicated generally at 104 with a release latch 106 (or “latch handle assembly”), at least one pivotal member 108 with detent, e.g., spring loaded detent, on the pivotal portion 111, and at least one rear mounting mechanism. Any of these features are located on either side of the assembly 100, preferably, on both sides of the assembly. Most preferably, the right half of the assembly 100 and corresponding features are substantially mirror image/symmetrical to the left half of the assembly 100 and corresponding features depicted in the figures. However, the latch mechanism 104 is such that only one of either release latch 106 (or “handle” or “release lever”) need be actuated by an operator for the latch mechanism 104 to be disengaged on both sides to allow pivotal movement of the pivotal portion 111, as will be explained in greater detail below.
The assembly 100 also incorporates a front attachment assembly, such as previously described front attachment assembly 14, according to an embodiment of the present invention.
The assembly 100 also includes at least one cover 138, e.g., soft cover, operably connected to at least the pivotal portion 111.
Typically, the assembly 100 has at least one mounting bracket arrangement including a rear mounting bracket 101, e.g., L-shaped bracket, that rests on and/or is operably fastened in a U-shaped mounting bracket 103 by at least one fastener. However, alternatively, depending on the application a suitable portion of the assembly 100 is bolted, screwed, welded, riveted, additionally secured with adhesive and/or epoxy, or combinations thereof or otherwise connected to the U-shaped mounting bracket 103, or other suitably shaped bracket, and/or directly to the cargo bed, e.g., side walls of the bed, depending on the application. Preferably, at least one attachment portion 102 or “attachment block” is releasably locked into the vehicle bed via the rear mounting bracket 101.
The tonneau access cover panel assembly 100 is adaptable and incorporates in combination a cable-type assembly (cover is cable tensioned), tri-fold (e.g., cover is segmented and the assembly folds up generally in the direction toward the vehicle cab), roll-up (e.g., the assembly rolls up with the rest of the tonneau, soft panels, hard panels (e.g., two or more smaller hard sections with a living hinge in-line with pivot points), soft tri-fold, hard or rigid, soft or flexible, manual or electric, hybrid, or any other type of tonneau assembly and combinations thereof, depending on the application and predetermined vehicle needs.
The assembly 100 further includes a rear bow 110 and cross member 112. The rear bow 110 is coupled to both pivotal members 108, e.g., by at least one fastener such as a nut and bolt, etc, or, alternatively, integrally formed with the pivotal members 108. The rear bow 110 is also operably coupled to the cover 138 of predetermined tonneau cover material. The rear bow 110 is in sealing engagement with the tailgate for a weather tight seal. The cross member 112 is operably connected to both attachment portions 102, e.g., slid over a mounting member that is formed on the portions 102 and secured by a plurality of fasteners 109.
The pivotal members 108, rear bow 110, and second cross member 112 are made of a metal, preferably, aluminum. However, depending on the particular application, it is also within the scope of the invention to manufacture the pivotal members 108, rear bow 110, and/or cross member 112 of different materials such as steel, composite plastic, or other suitable impact resistant material to withstand predetermined cycling requirements and load without departing from the scope of the invention.
The latch mechanism 104 includes a release latch connector bar 105 having a small rod like structure 114, preferably of metal, that is operably connected, e.g., partially inserted into the connector bar 105, to both ends of the connector bar 105 by at least one fastener 107, e.g., roll pin. Each latch handle assembly 104 includes a hook feature 116 that is biased by a detent mechanism 117, such as a spring, preferably, a torsion spring. The hook 116 locks into a respective corresponding feature 115 in the assembly, e.g., a recess with an abutting surface formed in the mounting member 101, and/or vehicle cargo bed frame. In addition to the connector bar 105, each corresponding rod 114 is also operably coupled to the respective release latch 106 handle, attachment portion 102, hook 116 and spring 117. Preferably, the rod 114 is inserted into holes in these adjacent parts to keep the parts together in operational contact. Alternatively, no rod 114 is used and the connector bar 105 is operably connected to these features. In a most preferred embodiment, when the attachment portion 102 is to be coupled to the mounting bracket 101, a forward surface 148 of the attachment portion 102 enters laterally into an opening 150 formed toward the top of the mounting bracket 101 and is held in the opening 150 by an upper surface 152 when the hook 116 is locked to the mounting member 101. When the hook 116 is selectively released, the attachment portion 102 is removable from the opening 150.
Lifting or otherwise manipulating one release latch 106, on either end, results in the rotation of both hooks 116 via the connector bar 105 to release the hook connection and release some tension. Thus, a user only needs to operate one latch 106; because of the rod 114 (on both ends)/bar 105, both sides are released allowing for selective rotation by the user to the fully open position and any intermediate position(s). To lock the attachment portion 102 into the closed position, the hooks 116 are brought back into engagement with the abutting surface 115 on the mounting bracket 101 and the pivotal portion 111 is rotated to engagement with the tailgate 142.
The pivotal portion's 111 pivot members 108 are pivotally connected to the attachment portion 102 by a second pin 118 or metal rod and has a spring loaded detent. The combination of a spring 120 backing an anterior block 121 against a posterior surface 108a of the pivotal members 122 locks the pivotal member 108 in up/down positions (open/closed). This also serves to prevent the pivotal members 108/rear bow 110 from bouncing in the open and/or closed positions during vehicle transit. Preferably, the spring 120 is a compression spring.
The rear bow 110 is operably adapted to be in sealing engagement with the tailgate shown generally at 142 (
According to an embodiment of the present invention, the rear bow 110 includes an operably shaped channel 124 to slidably receive and retain a seal 126. Most preferably, the seal 126 is a bulb seal having at least one bulb. Although an exemplary channel 124 is shown, it is understood that the channel 124 can have any shape suitable for receiving an opposing connecting feature of the seal 126. The seal 126 is slid into the channel 124 and operably held in place by friction and/or at least one fastener and/or at least one other suitable feature to prevent the seal 126 from leaving the channel 124. Preferably, the channel 124 is generally located on the underside of the rear bow 110. Most preferably, channel 124/bulb attaches toward the leading edge of the rear bow 110. The bulb seal 126 goes against a predetermined portion of the tailgate for a weather resistant seal. The spring loaded detent 120/121/108 pushes the pivotal members 108/rear bow 110 in the direction toward the tailgate and therefore pushes the seal 126 against the tailgate.
Generally, the seal 126 is an extruded material of polypropylene, thermoplastic elastomer, soft TPE (Thermoplastic Elastomer), rigid PVC, flexible PVC, PVC vinyl, PVC rubber, ABS, a structural ABS (Acrylonitrile Butadiene Styrene), polypropylene, or other plastic material or other suitable material and combinations thereof suitable for providing a structural portion to remain in the channel 124 and additionally a resilient seal portion, e.g., bulb.
The rear bow 110 also includes an operably shaped second channel 128 to receive a mounting portion of the tonneau cover. Preferably, the mounting portion is an extrusion 129 is sewn to the cover and slid into the second channel 128. The extrusion/cover 128 is held in place by friction and/or at least one fastener and/or at least one other suitable feature to prevent the cover from leaving the second channel 128. Most preferably, no fasteners are used to connect the cover to the channel which is a significant benefit. In one embodiment the channel 128 is generally located on the underside of the rear bow 110 toward a leading edge when in the closed position. This allows the cover to wrap up and around the bow edge and back so that the frame of the assembly 100 is not visible. Preferably, the channel 128 is located on the leading edge of the rear bow 110 when in the closed position. The mounting portion is a predetermined shape received in the channel 128 in the rear bow 110. Other suitable arrangements, P-welts, C-shaped channels, can be used to couple the cover 138 to a bow (such as in known manners described in U.S. Pat. No. 6,322,129 B2 incorporated herein by reference).
According to an embodiment of the present invention, in operation, the user flips the pivotal portion 111 rearward to a first open position to gain partial access to the cargo bed structure. When a larger opening into the structure is desired, the user rotates the release latch 106 in a first direction which disengages the hook 116 from the mounting bracket 101 allowing the pivotal portion 111 with the cover 138 attached to be rolled, or otherwise suitably articulated, as far back toward the front attachment assembly 14 as desired. Rolling the unit all the way to adjacent the front attachment assembly 14 provides a fully uncovered opening into the cargo bed.
In a preferred embodiment, only the mounting bracket arrangement with the rear mounting bracket 101 and mounting bracket 103 stays in the affixed position after unlatching the hooks 116 allowing selective rotation of the rest of the assembly to a fully open position, e.g., positioned adjacent the cab for greatest access into the cargo bed. In a preferred embodiment, once the hooks 116 are unlatched, the cover with the attached pivotal portion 111 is able to be rolled up and stowed toward the front attachment assembly 14. Straps can be used to keep the rolled assembly 100 in the fully open position and/or any intermediate open position(s).
According to the present invention, there are predetermined desired positions of the assembly 100 with predetermined amounts of access into the cargo bed of the vehicle indicated generally at 130. The assembly 100, preferably the rear bow 110, is in sealing engagement against the tailgate 142 in a closed position. When in the first open position, the pivotal portion 111 has been pivoted back to create an opening of predetermined width, e.g., not more than 6 inch opening. In one or more predetermined deployed position(s) the assembly 100 is provided in combination with a tri-fold cover or any other type of tonneau cover assembly, and when deployed, an opening of predetermined width, e.g., quarter, half, and/or full top access into the cargo bed. These examples are exemplary and not limiting.
Generally, when the assembly 100 is in the first open position the width of the opening into the bed is at least 3 inches, typically 3-10 inches, preferably 4-8 inches, most preferably about 6 inches.
In one embodiment, another safety advantage option of the present invention is that the assembly 100 cannot be operated unless the tailgate is unlatched and/or unlocked.
In one preferred embodiment, a cable attachment feature 134 is provided on the attachment portion 102 for attaching cable(s) 135 for a cable tonneau cover assembly. Preferably, the cable 135 is not a hard attachment to the vehicle to help manage the cable/cover/sealing. The cable 135 eliminates Velcro hook and loop for sealing, which is a significant benefit over conventional systems. Rather, the cable 135 holds the cover 138 taut as desired along at least the outboard sides of the cover 138. The cable 135 is also attached to at least the front attachment assembly 14, e.g., to the attachment block 24. Other attachment point(s) are contemplated depending on the application without departure from the scope of the present invention. Other cable-type arrangements are contemplated depending on the application without departure from the scope of the present invention. According to an embodiment of the present invention, at least one weather resistant seal is provided on the cover, e.g., sewn and/or adhered, near the sides and/or rear of the cover 138.
Referring more particularly to
Preferably, a plurality of pockets 140 are provided to hold both ends of center management bow(s) 144. There are provided at least one, preferably at least two, most preferably at least three, center management bows 144. The bows 144 set the height and eliminate aluminum rails and attachment features, which such rails are conventionally required. The center management bows 144 also assist with cover management. The pockets 140 have a predetermined suitable height and width depending on the application. The pockets 140 also set the distance between each center management bow 144. The center management bows 144 run cross-car. The cable pocket 136 preferably runs past outwardly from the pockets 140 for center management bows 144.
When the top cover is fabric or other flexible material these pockets 140, most preferably, of molded acrylonitrile butadiene styrene (ABS), having predetermined suitable thickness, are sewn and/or adhered to at least the cover. The pockets 140 are on the underside surface of the cover 138, thus not visible when the cover 138 is in the closed position. Each end of the center management bows 144 are slid into an opening 146 in a respective pocket 136. Preferably, the pockets 140 rest on existing original manufacturer bed features/rails and sets the height and cross-car relative to the bed. The pockets 140 sets the height and are thin enough to sew to the cover material. The pockets 140 set the distance between the bows 144 and, in combination with the bows 144, help with moving the assembly to a fully open position and any intermediate open position(s), e.g., to help with rolling the cover/assembly. The pockets 140 also eliminate the addition of aluminum rails for the cover and eliminate the tongue and loop for cover sealing, which are significant advantages.
While a cable-type tonneau cover assembly is depicted in the figures, the assembly 100 can be used in combination with any type of tonneau cover assembly without departing from the scope of the present invention.
