Abstract
A vehicle cargo box system is provided including a first brace member affixed to a surface of a wall of the vehicle, a first panel rotatably fastened to one edge of the brace member, and a second panel rotatably fastened to one edge of the first panel so as to enable the first and second panels to be deployed by rotating the respective panels in the appropriate direction. In this manner, a secure box-shaped enclosure is formed adjacent the cab portion of the vehicle and provides for storing tools and implements therein. When the cargo box is not required to be deployed, the respective panels are rotated in the appropriate opposite direction and are secured against the first brace member so as to increase the available cargo area on the bed surface of the vehicle. An optional second brace member is provided for engagement to the second panel to prevent unintended rotation of the second panel. Furthermore, optional lock systems can be provided for securing the system or components thereof to the various surfaces of the vehicle.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates, generally, to a vehicle cargo box, and more specifically, to a vehicle cargo box system that defines an enclosure that is capable of being selectively positioned in a first deployed position and a second stored position, wherein a first panel of the enclosure is rotatable relative to a first brace member affixed to a wall surface of the vehicle, and a second panel of the enclosure is rotatable relative to the first panel of the enclosure and is intended to engage an optional second brace member affixed to the bed surface.




2. Description of the Related Art




Pickup trucks and like vehicles have cargo areas that are employed for utilitarian purposes. As is well known in the art, such vehicles typically include a forward cab portion in which the vehicle operator sits and a rear cargo area for receiving cargo and the like. As noted, the cargo area is typically disposed adjacent and to the rear of the cab. The cargo area is typically defined by a substantially flat bed surface and a pair of upstanding sidewalls spaced from one another on either side of the bed surface. In addition, the vehicle typically includes a rear wall or “tailgate” that extends between the pair of sidewalls at one end of the bed surface and a front wall located at the other end of the bed surface opposite to the tailgate.




Numerous accessories have been developed for the purpose of augmenting the utilitarian functions of the cargo area in such vehicles. For example, toolboxes and other similar storage devices have been employed to provide a secure enclosure for storing tools and other valuable implements in the otherwise open cargo area of vehicles, such as pickup trucks. Such toolboxes and the like are typically mounted between the sidewalls and the front wall proximate to the cab of the vehicle. While such toolboxes adequately function for their intended purposes, they also act to reduce the remaining available cargo area of the vehicle. Therefore, the consumer has had to make a difficult choice between either having an adequate amount of cargo area or ensuring the security of the consumer's tools and implements.




Accordingly, there has been increased interest in structures that can selectively function as a storage device when needed and then can be either easily removed or stowed out of the way so as to provide increased cargo area to the vehicle.




One proposed approach to overcoming this problem could be found with reference to U.S. Pat. No. 6,257,640 to Leitner et al., the entire specification of which is incorporated herein by reference, which discloses a collapsible storage device including a first panel and a second panel, with one end of the first panel rotatably secured to one wall of a vehicle bed. One end of the second panel is rotatably secured to the opposite end of the first panel. The device has a deployed or storage position in which the first panel is substantially horizontal and the second panel is substantially vertical so that the two panels, in cooperation with the existing walls of the bed, form an enclosed container. The device also has a folded position in which the second panel is folded against the first panel, and the first panel together with the second is folded against a wall of the vehicle bed. The collapsible storage device has an arrangement for locking the device in the deployed and/or the folded position. Alternatively, the device may have an arrangement means for locking the two panels together during deployment and/or retraction, or the device may be interposed between two storage bins along a wall of the vehicle bed. A track or tracks may be provided on one or both sides of the storage device to coact with a track follower on one or both sides of the second panel to provide easier collapse or deployment of the device.




Although the device described in U.S. Pat. No. 6,257,640 to Leitner et al. represented an improvement over conventional storage devices, it still suffered from several significant deficiencies, such as the fact that the first panel is directly mounted to the front wall of the bed at a single point along the upper end of the front wall. This creates a high stress area where the first panel is joined to the front wall as the first panel is repeatedly rotated upwardly and/or downwardly, as well as when heavy items (e.g., power tools, water coolers, and the like) are either placed or dropped onto the top surface of the first panel, despite the presence of the optional reinforcing members in both of the panels.




Accordingly, there remains a need in the art for a device that can function as a collapsible storage device for use in conjunction with the cargo area of pickup trucks for securing tools and implements therein, wherein the device is rugged and sturdy and thus can withstand the rigors of repeated heavy use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring generally to

FIGS. 1-7

, there is shown a vehicle


10


commonly referred to a pickup truck having a forward cab portion


12


and a rearward bed portion


14


. The bed portion


14


includes a bed surface


16


(having at least one rear wheel housing


18


) surrounded by a pair of spaced and opposed sidewalls


20


,


22


, a front wall


24


(adjacent to a surface of the cab portion


12


), and an optional tailgate


26


. The bed surface


16


is particularly useful for receiving cargo and loads, and generally speaking, the greater the area of the bed surface


16


, the more desirable to consumers.




Disposed within the bed portion


14


is the cargo box system


100


, in accordance with the general teachings of the present invention. The cargo box system


100


primarily includes a brace member


102


, a first panel


104


, and a second panel


106


.




The brace member


102


is preferably comprised of a rigid durable material that is capable of withstanding repeated shocks and impacts. Suitable materials include metals, ceramics, composites, thermoplastics, thermosets, woods, and like materials. The exact configuration of the brace member


102


is not thought to be critical to the success of the present invention, provided that the configuration is capable of withstanding repeated shocks and impacts. By way of a non-limiting example, one possible configuration of the brace member


102


includes a first elongated member


200


and a second spaced and opposed second elongated member


202


interconnected by a pair of connecting members


204


,


206


, as specifically shown in FIG.


6


.




The brace member


102


is preferably fastened along the upper and lower edges of the front wall


12


, and extends from one end of the bed portion


14


to the spaced and opposed other end of the bed portion


14


. By way of a non-limiting example, the first elongated member


200


is fastened to the upper edge of the front wall


12


and the second elongated member


202


is fastened to the lower edge of the front wall


12


. The fastening can be accomplished in any number of conventional methods, including, but not limited to screwing the respective members


200


,


202


to the front wall via holes


200




a


,


202




a


, respectively.




The intended purpose of the pair of connecting members


204


,


206


is to absorb any shocks, stresses, or forces applied to the first elongated member


200


and channel those shocks, stresses, or forces away from the first elongated member


200


towards the second elongated member


202


, which is preferably abutting against the bed surface


16


. In this manner, the first elongated member


200


is capable of absorbing considerable amounts of stress without unintentionally separating from the front wall


12


.




A surface of the brace member


102


is rotatably fastened to a surface of the first panel


104


, so that the first panel


104


is rotatable about a substantially horizontal axis. The rotatable fastening can be accomplished in any number of conventional methods, including, but not limited to the use of a hinge. The first panel


104


preferably extends from one end of the bed portion


14


to the spaced and opposed other end of the bed portion


14


. The first panel


104


preferably includes an inner face


104




a


and an outer face


104




b.






The first panel


104


is preferably comprised of a rigid durable material that is capable of withstanding repeated shocks and impacts. Suitable materials include metals, ceramics, composites, thermoplastics, thermosets, woods, and like materials.




A surface of the first panel


104


is rotatably fastened to a surface of the second panel


106


, so that the second panel


106


is rotatable about a substantially horizontal axis. The rotatable fastening can be accomplished in any number of conventional methods, including, but not limited to the use of a hinge. The second panel


106


preferably extends from one end of the bed portion


14


to the spaced and opposed other end of the bed portion


14


. The second panel


106


preferably includes an inner face


106




a


and an outer face


106




b.






The second panel


106


is preferably comprised of a rigid durable material that is capable of withstanding repeated shocks and impacts. Suitable materials include metals, ceramics, composites, thermoplastics, thermosets, woods, and like materials.




It is intended that the second panel


106


is capable of being collapsed into, or enveloped by, the inner face


104




a


of the first panel


104


. Accordingly, the inner face


104




a


is preferably provided with a recess or receptacle therein for receiving the second panel


106


.




An optional component of the system


100


is a second brace member


300


that is preferably fastened to the bed surface


16


, as specifically shown in FIG.


6


. The fastening can be accomplished in any number of conventional methods, including, but not limited to screwing the second brace member


300


to the bed surface


16


via holes


300




a


,


300




b


, respectively. The second brace member


300


preferably extends from one end of the bed portion


14


to the spaced and opposed other end of the bed portion


14


. With specific reference to

FIG. 7

, an optional configuration of an alternative second brace member


400


is shown with fins


402


for added strength and stability.




The second brace member


300


, and any alternative design thereof, is preferably comprised of a rigid durable material that is capable of withstanding repeated shocks and impacts. Suitable materials include metals, ceramics, composites, thermoplastics, thermosets, woods, and like materials.




It is intended that the second brace member


300


engage a surface of the second panel


106


so as to prevent the unintended rotation of the second panel


106


. By way of a non-limiting example, by placing the second panel


106


in back of the second brace member


300


, it would be difficult for the second panel


106


to hyper-rotate forward in the event the contents of the cargo box system


100


shifted or the cargo box system


100


were over-packed. In this case, a means for preventing the second panel


106


from unintentionally rotating backwards would have to be provided (e.g., a linkage or bracket). By way of another non-limiting example, by placing the second panel


106


in front of the second brace member


300


, it would be difficult for a thief to kick in the second panel


106


as the second brace member


300


would prevent any substantial movement of the second panel


106


. By way of still another non-limiting example, a male- or female-shaped surface of second panel


106


can mate with a complementary male- or female-shaped surface of the second brace member


300


.




Once the system


100


is deployed, it can serve as a storage device for securing tools, implements, and other objects, in the same manner that conventional cargo boxes function. In order to safely secure these items, the system


100


can be provided with one or more lock systems


400


. By way of a non-limiting example, the lock system


400


can include a rotatable cylinder that insert one or more rods into one or more pre-drilled holes formed in one or both of the sidewalls


20


,


22


, respectively, so that it is impossible to more either first panel


104


and/or second panel


106


once the lock system


400


has been actuated.




Additionally, when the system


100


is in the deployed position it is not uncommon for heavy items to be dropped or placed onto the outer face


104




b


of the first panel


104


. In conventional cargo box designs, the first panel would normally be directly fastened to the first wall. These forces would create an enormous amount of stress at the fastening point between the first panel and the first wall, potentially causing the first panel to separate from the first wall. The present invention avoids this problem by use of the brace member


102


that absorbs the majority of the stresses caused by the imparting of these forces and directs them away from the fastening point between the first panel


104


and the first wall


12


.




Referring specifically to FIGS.


5


and


8


A-


8


D, positioning the system


100


between a deployed position and a collapsed or stowed position, and vice versa, is very simple.




From a deployed position, the operator releases any locks securing the system


100


in place. The operator then preferably grabs an optional handle


500


preferably formed on the first panel


104


and pulls the first panel


104


upwardly. This in turn causes the second panel


106


to rotate vertically about the pivot point formed with the first panel


104


. As the first panel


104


continues to rotate to assume a nearly vertical position, the second panel


106


also begins to rotate horizontally about the pivot point formed with the first panel


104


to also assume a nearly vertical position. When the a respective panels


104


,


106


are fully rotated, they are preferably abutting and adjacent to one another in a collapsed, recessed or nested position. The respective panels


104


,


106


are then rotated in tandem in the opposite horizontal position so as to assume a substantially vertical position, with the respective panels


104


,


106


parallel to the brace member


102


, with the second panel


106


being adjacent to the brace member


102


. The respective panels


104


,


106


may then be locked or otherwise secured in place to prevent unintentional partial redeployment of the system


100


.




From a stowed position, the operator releases any locks (not shown) securing the system


100


in place. The operator then preferably grabs the optional handle


500


preferably formed on the first panel


104


and pulls the first panel


104


outwardly towards the operator. This in turn causes the first panel


104


to rotate vertically about the pivot point formed with the second panel


106


. As the first panel


104


continues to rotate to assume a nearly horizontal position, the second panel


106


(which was stowed within the recess formed in the inner face


104




a


of the first panel


104


) begins to rotate horizontally about the pivot point formed with the first panel


104


to assume a nearly vertical position. When the respective panels


104


,


106


are fully rotated, the system


100


is in its fully deployed position.




The foregoing description is considered illustrative only of the principles of the invention. Furthermore, because numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and process shown as described above. Accordingly, all suitable modifications and equivalents that may be resorted to fall within the scope of the invention.
