While the prior art offers various methods to better utilize the bed of a pickup truck, none present an adjustable shelf that works in combination with a rigid canopy or camper shell. The manner by which the present invention provides a convenient and removable, extra storage space within a vehicular camper shell will become apparent in the further description, particularly when read in conjunction with the accompanying drawings.
SUMMARY OF THE INVENTIONThis invention is directed to a sliding, adjustable shelf assembly for mounting over a vehicle bed, such as for a pickup truck. More particularly, the invention relates to the combination of a vehicle, i.e. pickup truck having a generally flat rearwardly extending bed defined by a floor and a pair of upwardly extending side walls, and a rigid canopy overriding and extending over the bed to provide cover thereto. The adjustable, sliding shelf assembly is adapted to be positioned on the side walls in sliding contact with the canopy. The shelf assembly comprises a frame composed of a pair of U-shaped members, each said member having a base and two free arms extending perpendicular to said base. Means are provided to join and align an arm of each U-shaped member, whereby to fix the spaced apart bases to a distance equal to the distance between the side walls. Further, at least a pair of spring biased roller members are included and positioned to laterally extend from each base and arranged to override the side walls in contact with the canopy. Finally, a pair of planar, overlapping panel members are positioned on the frame for receiving items to be transported thereon. Preferably, the panel members include a transverse support to ensure rigidity to the panel members.
Accordingly, an object of this invention is the provision of a space saving, adjustable shelf assembly for use with a pickup truck having a camper shell mounted thereon.
Another object hereof lies in the use of an adjustable, sliding shelf assembly that utilizes plural, spring biased roller members that help to maintain the stability of the assembly when mounted over the bed of a pickup truck.
A further object of the invention is the enhanced storing and transporting capabilities of the pickup truck so equipped.
These and other objects will become more apparent to a person skilled in the art from a reading of the following specification.
The present invention relates to an adjustable, slidable, shelf assembly to be used in conjunction with a vehicle, such as a pickup truck, having a rearwardly extending flat bed, and a pair of parallel side walls mounting a rigid canopy, such as a camper shell. The assembly, intended to provide added storage area within the canopy for transporting a variety of items, will now be described with regard to the several Figures, where like reference numerals represent like components or features throughout the several views.
The assembly 10, as more fully illustrated in
Extending from each respective base 20 is at least a pair of spring biased roller members 26. Such roller member as shown in exploded fashion in
Overriding the frame member, are a pair of overlapping planar panels 42, 44, such as wood, a light weight metal, i.e. aluminum, or plastic to function as the supporting surface to goods to be stored thereon for transportation, see
To set up the shelf assembly 10, the respective U-shaped members 18 are interfitted with intermediate members 24 to a rectangular size consistent with the side walls 12 of the truck bed. The roller members 26 thus will lie over the respective side walls 12 with the guide member 38 abutting the inner wall of the canopy 14, then overlaid by the panels 42, 44. It was discovered that canopies, or camper shells, which may be fitted over and fixed to said side walls, typically are aerodynamically designed with upstanding side walls tapering in a convergent manner toward the front of the vehicle, or pickup truck. However, by the use of spring biased roller members 26, the shelf assembly 10 may easily be shifted along the side walls 12 with the respective roller members 26 being urged toward the frame member 16. Even as the roller members 26 are laterally moved inwardly, its respective coil spring 40 counteracts such movement to maintain each guide member 38 in contact with the canopy inner wall.
Since the preferred shelf assembly of this invention has a longitudinal dimension equal to about one-half the length of the truck bed, and thus is movable, a typical stored position would be forward toward the cab. However, in use, as a table or working surface, the assembly would be moved rearwardly toward the open or accessible end of the bed. In such position, it may be desirable to lock the assembly against an inadvertent movement.
It is recognized that changes, variations and modifications may be made to the shelf assembly of this invention without departing from the spirit and scope of the invention. Accordingly, no limitation is intended to be imposed thereon except as set forth in the appended claims.
