Background of the Invention
1. Field of the Invention
This invention pertains generally to transporting cargo and the like in vehicles, and more particularly to a utility shelf for use with pick-up trucks having camper shells.
2. Description of the Background Art
It is common for owners of pick-up trucks with open beds to cover those beds to protect cargo or the like which is being transported. Frequently a camper shell is used to provide protection from the elements as well as to guard against theft of articles being transported In many instances, when the driver of the vehicle requires access to an article in the cargo bed, the vehicle must be stopped and access gained through the rear door of the camper shell.
Now that sliding windows are being installed in the rear of pick-up truck cabs, the driver has access to the cargo area without having to leave the vehicle. However, access is limited to the driver's arm reach which generally is not long enough to reach items on the floor of the cargo bed This limitation makes it inconvenient to gain access to lunch boxes, maps, hand tools, and other small items which the driver might require. Therefore, there is a need for a convenient shelf apparatus which can be positioned within reach of the driver and which can hold small items for easy access, some items being accessible without having to stop the vehicle.
Various approaches to shelves and cargo boxes have been previously developed. For example, U.S. Pat. No. 4,381,715 issued to Forman on May 3, 1983, discloses an adjustable shelf mounting system capable of bearing heavy loads. U.S. Pat. No. 1,852,357 issued to Merhar on April 5, 1932, discloses a combination serving tray and table for automobiles. U.S. Pat. No. 2,768,043 issued to Kristoff et al. on Oct. 23, 1956, discloses an adjustable service tray for use in motor vehicles. U.S. Pat. No 4,900,080 issued to Morris II on Feb. 13, 1990, discloses a partial cover for a pick-up truck bed. U.S. Pat. No. 4,635,992 issued to Hamilton et al. on Jan. 13, 1987, discloses a moveable vehicular storage box. U.S. Pat. No. 4,938,519 issued to Schlacter on July 3, 1990, discloses a security enclosure for open deck vehicles. U.S. Pat. No. 4,944,544 issued to Dick on July 31, 1990, discloses a vehicle accessory storage device. U.S. Pat. No. 4,674,665 issued to Van Kirk on June 23, 1987, discloses a vehicle tool box with peripheral drain means. None of these patents, however, disclose a utility shelf for campers which is accessible from the cab of a pick-up truck.
Examples of devices which provide for storage of cargo and which are accessible through the rear window of a pick-up truck can be seen in U.S. Pat. No. 4,892,346 issued to Berlin on Jan. 9, 1990, which discloses a drop in utility enclosure apparatus having a cargo chamber and shelves, as well as a sliding window which is accessible through the rear window of a truck to which the apparatus is mounted; and U.S. Pat. No. 3,249,382 issued to Swithenbank on May 3, 1966, which discloses a detachable cargo box which is accessible through the rear window of the truck cab against which the apparatus is mounted, and which has a an expansive rear window through which the driver can see for safety. Both of those devices, however, are effectively scaled-down versions of camper shells and neither of them are adaptable to a pick-up truck already having a camper shell. Nor are either of those devices easily adjustable to fit any width of pick-up truck.
The foregoing patents reflect the state of the art of which the applicant is aware and are tendered with the view toward discharging applicant's acknowledged duty of candor in disclosing information which may be pertinent in the examination of this application. It is respectfully stipulated, however, that none of these patents teach or render obvious, singly or when considered in combination, applicant's claimed invention.
Summary of the Invention
The present invention is a utility shelf for use with pick-up trucks to which camper shells are attached, and which have sliding windows or the like in the rear of the truck cab through which access to the area enclosed by the camper shell can be gained. The apparatus generally comprises a lower support member and an upper back member, the back member being mounted perpendicular to the support member in a position which is away from the vehicle cab. In the preferred embodiment, the apparatus has two separable shelf halves, each of which has a support member and a back member. The support member of one shelf half contains slotted guides whereas the other support member contains holes which can be aligned with the slotted guides in the first support member. Carriage bolts are inserted through the holes and slotted guides, thereby making the apparatus adjustable in width. When the shelf halves are assembled, there exists a cutout portion centrally located in the back of the apparatus to provide a zone of clear vision to the rear of the vehicle. Also, the sides of the apparatus can be angled to fit the shape of the side walls of a typical camper shell. An alternative embodiment of the invention is fixed in width and utilizes one-piece support and back members.

Description of the Preferred Embodiments
Referring more specifically to the drawings, for illustrative purposes the present invention is embodied in the apparatus generally shown in FIG. 1 through 4. It will be appreciated that the apparatus may vary as to configuration and as to details of the parts without departing from the basic concepts as disclosed herein.
Referring to FIG. 1, the apparatus is installed on a pick-up truck 10 having a cab 12, cargo bed 14, rear cab window 16, side walls 18, and camper shell 20. The apparatus is positioned in the area of cargo bed 14 immediately behind cab 12. Access to the apparatus is gained from cab 12 by reaching through window 16. Window 16 will either be an opening in the back of cab 12 or, more typically, a sliding rear window.
Referring to FIG. 2 and FIG. 3, first support member 22 is flat and generally rectangular in shape. Located near one end of first support member 22 is a plurality of holes 24 through which bolts 26 can be inserted. Second support member 28 is also flat and generally rectangular in shape. Located near one end of second support member 28 is a plurality of elongated slots 30 which ar aligned longitudinally between the ends of second support member 28. When first support member 22 is stacked on top of second support member 28, bolts 26 extend through holes 24 and slots 30 to join the two support members. Wing nut 32, lock washer 34 and flat washer 36 engage bolt 26 to secure the two support members in place. Since slots 30 are elongated, first support member 22 slidably engages second support member 28 and the relative position between first support member 22 and second support member 28 is adjustable. This permits the apparatus to be adjusted in width to fit various sizes of cargo beds. Note also, that holes 24 are preferably square and bolts 26 are preferably carriage bolts to provide for convenient tightening of the two support members.
While first support member 22 and second support member 28 can rest on top of side walls 18 to transverse cargo bed 14, it is preferable to fasten them to side walls 18 to prevent sliding. This can be accomplished with double-sided tape, brackets mounted to the underside of the support members as well as to the side walls, or by using bolts 38 extending through holes 40 in the support member as well as through matching holes in side wall 18, and securing the assembly in place using wing nut 42, lock washer 44, and flat washer 46. Double-sided tape is preferred for removable installations, whereas the other approaches are suitable for a more permanent installation.
First back member 48 is joined to first support member 22 along corresponding edges as shown, with first back member 48 being oriented vertically. First back member 48 and first support member 22 can be joined in any manner which provides for a rigid bond, such as nails, screws, glue, or the like. Second back member 50 is similarly joined to second support member 28 in a vertical orientation. Installation of the apparatus is such that first back member 48 and second back member 50 are positioned toward the rear of cargo bed 14 to effectively create a compartment between cab 12 and the back members.
First back member 48 includes a notch 52 located near the end of first support member 22 which will be joined to second support member 28. Second back member 50 includes a similar notch 54. These notches extend from the upper lengthwise edges of said back members toward the lower lengthwise edges to form a synclinal shaped cutout, or opening 56, through which the driver's vision is unimpaired. To further increase safety, first back member 48 and second back member 50 are preferably made of a transparent material such as plexiglass. The notches extend only so far as to provide a clear, unimpaired view, while still maintaining a lip above the support members against which articles being transported can rest.
Referring to FIG. 3 and FIG. 4, first back member 48 has an angled end 58 as does second back member 50, the angle matching the angle which is commonly found in the side wall of camper shell 20. Also note the use of vertical stem wall 60. This permits angled end 58 to abut the inner wall of camper shell 20 while still permitting the apparatus to be removed by rotation and sliding.
An alternative embodiment of the apparatus is shown in FIG. 5, where the width of the apparatus is fixed. Support member 62 is a one piece flat rectangular member to which back member 64 is attached in a vertical orientation, back member 64 also being of one piece construction.
The apparatus, in either of the embodiments disclosed as well as their equivalents, can be fabricated from wood, plastic, and similar lightweight, rigid materials. However, where clear vision is important, a transparent material such as plexiglass is preferred.
Accordingly, it will be seen that this invention provides for convenient access to articles being transported in the cargo bed area of a pick-up truck enclosed by a camper shell. Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus the scope of this invention should be determined by the appended claims and their legal equivalents.
