ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus for increasing the load carrying capacity of pickup trucks, and particularly to an articulable frame arrangement for increasing that load carrying capacity of a pickup truck.
2. Prior Art
About one in four of every vehicles on the road in the United States today is a pickup truck. Those pickup trucks are often utilized as both a family vehicle and as a utilitarian vehicle for home owners and service personnel. Theirs is often a dual function vehicle.
An attempt at dual function use of a pickup truck is shown by a truck rack adapter called the Rail 'N Rack System™ which permits a conversion of pickup truck bed rails into a rack. It becomes an overhead rack from a pair of bed rails. The bed rails, however, appear to require a supplemental crossbar attachment inasmuch as they are hinged at the rearwardmost point of the truck bed to provide the rear rack assembly. This is somewhat complicated. If the cross bar on the rack were constantly maintained on the side rails, they would take up valuable cargo space when the rack was not in its full upright orientation.
It is an object of the present invention to overcome the disadvantages of the prior art.
It is a further object of the present invention to provide a pickup truck with a simple, efficient, stowable rack arrangement which is not in the way of the cargo bed when the rack is not in its extended orientation but in its “stowed” orientation.
It is a yet further object of the present invention to provide a pickup truck rack arrangement that is simple to set up and which rack arrangement takes up minimum space and is unobtrusive within the cargo bed or on the side rails of the pickup truck.
BRIEF SUMMARY OF THE INVENTION
The present invention relates to a bed extender arrangement for a pickup truck. The pickup truck comprises a cab and a cargo bed thereadjacent. The cargo bed comprises an elongated floor defined by an arrangement of first and second parallel side walls, a front end wall, and a hinged tailgate extending off of the rear edge of the floor.
The bed extender arrangement in a first embodiment, comprises a generally U-shaped rail having a first side arm and a second side arm. Each side arm has a first end which is hingedly attached to an upper portion of the sidewall of the bed of the pickup truck. Each sidearm has a second end with a crossbar extending thereacross.
The U-shaped rail in the first embodiment, may be arranged so that its pair of side arms preferably rest upon or adjacent the upper edge of the sidewall at the forward half end of the bed of the pickup truck. The crossbar is thus stowed adjacent the rear wall of the cab. When it is desired to utilize the U-shaped rail to assist in cargo carrying capacity, the U-shaped rail is pivoted 180 degrees about it's hinges on the sidewall of the cargo bed, so that the crossbar and the side arms subsequently rest on the upper edge of the sidewall across a rear half portion of the bed of the pickup truck. In that manner, the crossbar provides a transverse support to long cargo such as ladders or pipes or timber.
In a further embodiment of the present invention, the side arms of the U-shaped rail are slidably disposed in a pair of tracks on the upper edge of the side wall of the bed of the pickup truck. Thus, the crossbar may be extended rearwardly over the tailgate and beyond the rear end of the sidewalls of that pickup truck.
In yet a further preferred embodiment of the present invention, a plurality of spaced-apart anchor points may be located on the upper edge of the sidewall. The side arms in this embodiment have a pin which mates into the anchor points and thus may be movably attachable to any one of those anchor positions spaced along the top of the sidewall to provide movability of the U-shaped rail either forwardly or rearwardly. This will enable that crossbar to be disposed at any location from the forward end of the pickup truck bed to beyond the rear end of the sidewalls and above a folded down tailgate, if desired, depending upon the orientation of the U-shaped rail is directed forwardly or rearwardly.
The crossbar in this embodiment may also be defined by a panel to function as a wall that may be disposed across (between) the sidewalls or beyond the rear edge of the sidewalls of the pickup truck bed. Thus that wall would function as a divider for cargo within the pickup truck bed or it would function as a rearwardmost wall, resting upon the tailgate in its folded down orientation.
That rearward wall in yet a further preferred embodiment may be attached to an extension of each sidearm, so as to hingedly extend therefrom to act as a ramp from the tailgate assembly.
The invention thus comprises a rack apparatus for improving the cargo carrying capacity of a pickup truck, said truck having a cab portion, a bed portion defined by a floor surface, a pair of sidewalls, a forward wall, said apparatus comprising: a U-shaped frame having a pair of parallel side arms with a first and a second end, a cross bar attached to said first end of the arms, the U-shaped frame movable to and from a stowed-away position at a front end of the bed to a rearward position; said arms attached to said side walls of the pickup truck. The side arms may be slidable on the side walls of the truck. The side arms may be telescopable to permit the side arms to be lengthwise adjustable. The cross bar may comprise a panel arranged perpendicular to the side arms. The side walls of the truck may have anchor points thereon to permit adjustment of position of the U-shaped frame with respect to the bed. The cross bar may be secured to the arms by a pair of exchangable connectors.
The invention may also include a method of improving the cargo carrying capacity of a pickup truck, comprising one or more of the following steps: arranging a generally U-shaped rack assembly having a pair of parallel side arms, on a forward end of a bed of the truck, the rack being secured to the truck by the side arms; moving the rack assembly from the forward end of the bed to a location rearward of the forward end of the bed; locating the rack to a position over a tailgate of the truck; telescoping the side arms to effect a change in length thereof; arranging a plurality of anchors on the side walls of the truck to permit the side arms of the rack to be moved from one anchor position to a second anchor position and pivoting the rack on a pair of hinge points from a forward position to a rearward position.
