Abstract:
A releasably mounted utility rack for organizing cargo in the cargo area of a work vehicle includes a frame which supports storage bins and a pair of spaced mounting rails. The mounting rails carry spaced-apart latches which correspond to the pre-existing seat catches integrally mounted to the floor of the vehicle. Each latch is pivotally mounted to its corresponding rail and pivots between an unlatched position and a latched position wherein the latch interlocks with a seat catch. Each latch also includes a retainer for retaining the latch in its latched position.

Description:
FIELD OF THE INVENTION 
     The present invention relates in general to a utility rack or storage cage for use in the cargo area of a vehicle, and in particular to a utility rack having a tie-down rail for releasably securing the utility rack to seat catches pre-existing in the floor of the vehicle. 
     BACKGROUND OF THE INVENTION 
     Many laborers and servicemen transport tools and supplies to the worksite in work vehicles. In order to more efficiently transport and access the tools and supplies, the work vehicles employed often contain utility racks or storage cages which support storage bins or containers. Frequently, these work vehicles are standard vans which have been converted into utility vehicles containing such racks. Heretofore, the van rear bench seats were removed and the utility rack was bolted or otherwise fastened to the van floor. This method of installing a utility rack is undesirable because it requires drilling into the vehicle floor. Drilling through the vehicle floor is dangerous and may void certain long-term vehicle warranties. Also, the resulting damage decreases the resale value of the vehicle, even if the seller undertakes the expense and labor of repairing the holes in the floor before resale of the vehicle. 
     SUMMARY OF THE INVENTION 
     The present invention provides a utility rack for organizing supplies and tools in the cargo area of a work vehicle which is releasably mounted to the seat catches exposed in the floor of the vehicle upon removal of the rear seats from the cargo area. The utility rack includes a frame which supports cargo bins, and a pair of spaced-apart rails attached to the frame in alignment with the vehicle seat catches. The rails carry latches which pivot into interlocking engagement with seat catches to secure the rails to the floor, thereby securing the utility rack within the cargo area. The rails also include retaining fasteners which hold the latches into interlocked engagement with the seat catches. 
     Accordingly, an object of the present invention is to provide a utility rack which is reusable and easily installed in a vehicle. 
     Another object of the invention is to provide a utility rack which releasably mounts to the pre-existing seat catches of a standard van. 
     Yet another object of the present invention is to provide a removably mounted utility rack which can be installed into and removed from a vehicle without damaging the vehicle.

     DESCRIPTION OF THE INVENTION 
     The embodiments disclosed below are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Rather, the embodiments selected for the description of the invention are disclosed so that others skilled in the art may utilize their teachings. 
     FIG. 1 shows utility rack 10 mounted in the rear cargo area of a standard van having a floor 26 with parallel longitudinally extending channels 24 containing spaced apart seat catches 22 of a standard configuration. Utility rack 10 includes a frame, generally referred to as 12, a cargo bin 14, and a pair of mounting rails 16. For simplicity, frame 12 is shown truncated with only one cargo bin 14. Of course, a typical frame 12 would extend approximately to the top of the cargo area and support several cargo bins 14. Frame 12 generally includes a plurality of frame members 18 which form multi-level shelving units for supporting the cargo bins 14. Frame 12 also includes lower cross-members 20 which are attached to mounting rails 16 as described below. 
     Mounting rails extend perpendicularly between lower cross members 20 and are mounted thereto using standard fasteners which extend through flanges 36 into cross members 20. Rails 16 are mounted in parallel relationship at a predetermined spacing which corresponds to spacing between recessed channels 24. 
     Referring now to FIGS. 2 through 4, mounting rails 16 include a pair of parallel sidewalls 28 connected together by a bottom web 30 which turns upwardly at each end 32 to form end walls 34 and outwardly to form flanges 36. An opening 37 is formed in each flange 36 to receive the fastener for attaching rail 16 to cross members 20 as described above. A pair of latches, generally referred to as 38, are disposed between sidewalls 28. The spacing between latches 38 corresponds to the standard spacing between seat catches 22. A pair of parallel, spaced apart feet 40 extend downwardly from bottom wall 30 adjacent each of the latches. As shown in FIG. 3, each foot 40 includes a notch 64 for aligning foot 40 onto seat catch 22. Bottom wall 30 forms an elongated slot 42 at each latch 38 which is positioned between a corresponding pair of feet 40 as best shown in FIG. 4. Bottom wall 30 also defines a bore 44 (FIG. 5) adjacent each slot 42 which receives a threaded fastener as further described below. 
     Since the structure and operation of each latch 38 is substantially the same, only one latch is described below. Referring now to FIGS. 5 through 8, latch 38 includes a lever arm 46 and a latching member or finger 48 which extends perpendicularly downwardly from the lever arm 46 through slot 42. Latch 38 pivots on the pivot rod 50 which extends through finger 48 between sidewalls 28. Finger 48 includes a notch 62 adapted to engage seat catch 22. Lever arm 46 includes a free end 58 which defines a bore 54. Bore 54 is substantially aligned with an upwardly projecting fastener 56 which is permanently mounted through bore 44 using standard techniques. Free end 58 also includes an upturned handle portion 60 for operating latch 38 as described in detail below. 
     Mode of Operation 
     The work vehicle is prepared for the installation of utility rack 10 by removing the rear bench seats from their respective seat catches 22 in the standard manner. Once mounting rails 16 are attached to frame 12 at locations along cross members 20 corresponding to the spacing between channels 24 in the vehicle floor 26, the utility rack 10 may be installed into vehicle cargo area. Mounting rails 16 are positioned over channels 24 and utility rack 10 is moved toward the rear of the vehicle until notches 64 in feet 40 align with seat catches 22. Utility rack 10 then drops downwardly onto seat catches 22 until feet 40 engage the bottom of recessed channels 24. The installer attaches utility rack 10 to floor 26 by grasping handle 60 of lever arm 46 and pivoting latch 38 downwardly toward bottom web 30 from its upwardly pivoted unlatched position (FIG. 6) to its latched position (FIG. 5). As latch 38 pivots downwardly, finger 48 pivots within slot 42 until seat catch 22 is engaged within notch 62. As should be apparent from the foregoing, a groove or depression must be present below seat catch 22 in recessed channel 24 to accommodate the portion of finger 48 which extends below feet 40 when latch 38 is moved into its latched position as shown in FIGS. 5 and 7. As lever arm 48 moves toward bottom web 30, fastener 56 threads through bore 54 of lever arm 48. When latch 38 is in its latched position (FIG. 5 and FIG. 7), a nut 108 is threaded onto fastener 56 to retain latch 38 in its latched position. The procedure is repeated for each latch 38. As such, rails 16, and therefore utility rack 10, are prohibited from moving longitudinally by notches 64 in feet 40 and vertically by notches 62 in fingers 48. 
     Utility rack 10 is removed from the vehicle by removing the retaining nuts 108 from fasteners 56, and lifting the lever arm 46 of each latch 38 upwardly away from bottom web 30. Finger 48 pivots about pivot rod 50 within slot 42 until latch 38 reaches its unlatched position (FIG. 6 and FIG. 8). After each latch 38 is moved into its unlatched position, utility rack 10 may lifted upwardly until seat catches 22 are no longer within notches 64 of feet 40. Utility rack 10 is then removed from the vehicle. The vehicle seats may then be replaced and the vehicle resold for other purposes. 
     While this invention has been described as having preferred embodiments, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within limits of the amended claims.
