Abstract:
A removable shelving component for vehicles uses permanently mounted vehicle internal side wall frames to removably attach shelving components with pin-into-hole and tongue-into-groove connection. Modularized, the shelving is customizable to suit any desired configuration.

Description:
BACKGROUND OF THE INVENTION 
     The invention relates to removable shelving, specifically removable shelving for commercial vehicles. Previous shelving is either permanent or difficult to remove. Shelving that attaches directly to the van walls damages the walls and/or their protective coatings. 
     SUMMARY OF THE INVENTION 
     A removable shelving arrangement for vehicles comprising permanent frame weldments which are attached to the vehicle internal side walls following the curve of the walls. Shelving assemblies mate to the frame weldments through pins into holes at the top and a tongue and groove maintained by retaining pins along the bottom length. The shelving may be configured with shelves, baskets, or any manner of custom configurations. Steel frame pieces are removable from the permanent frame as modules. They are built of steel with the different pieces welded together to form removable components.

     DETAILED DESCRIPTION OF THE INVENTION 
     The removable shelving arrangement for vehicles may be used in any vehicle. An embodiment specific to a 2000 FORD Econoline truck is described herein after. 
     Referring to FIG. 1, an overview of the installed shelving is shown. The shelving is built onto each side wall of the vehicle, with allowances being made for side doors where applicable. In this embodiment, a bulkhead assembly  1  is used to separate the front of the vehicle from the cargo area. The street side frame weldment  3  shown in FIG. 4 is mounted to the street side wall of the vehicle with permanent anchors  10  screwed or spot welded to the vehicle wall. The lower front portion of the street side frame weldment  3  as shown in FIG. 3 mounts to the back of the bulkhead assembly  1 . The curb side frame weldment  2  shown in FIG. 7 likewise mounts to the curb side vehicle wall. In this embodiment, the mounting and size of the curb side frame weldment takes into account a side door on the 2000 FORD Econoline truck. A floor mounting bracket  4  is affixed as shown in FIG. 2, to the floor of the curb side of the vehicle. 
     Each of the frame weldments are mounted to the vehicle wall following the angle of the vehicle wall as shown in FIGS. 5 and 8. 
     The frame weldments have matching L-shaped top and bottom bars  11 . The bottom L-shaped bar  11  is formed at an angle where the projecting part is parallel to the floor of the vehicle. The top L-shaped bar  11  has top holes  21  placed for the shelving assembly protrusion  22  to fit into. At the base, an L-shaped bar  11  provides a tongue which fits into a groove of a base frame  12 . As shown in FIG. 9, pins  20  hang on chains which will removably connect the base frame groove to the tongue of the frame weldments through bottom holes  23 . The base frame consists of a rack assembly, the back of which is a frame plate weldment  13 A as shown in FIG. 11, this consisting of a top frame plate and a bottom frame plate welded together forming a groove  13  as shown in FIG.  12 . The base frame has two legs  14  opposite the frame plate weldment  13 A, each of the legs  14  supplied with a leveling foot  15 . The base frame also has connections  16  at the side pieces for the vertical support elements  5  to be attached. On the street side, two shelf assemblies are used, and on the curb side, a single shelf assembly is used. The floor mounting bracket  4  is the base of a six-drawer cabinet  8  and bookshelf  7 , shown in FIG.  13 . 
     To install the removable shelving arrangement into the 2000 FORD Econoline truck as described above, a base frame  12  with shelving assembly attached is brought to the van and pivoted so that the shelving assembly protrusions  22  at the top of the shelving unit mate with the holes  21  at the top of the street side frame weldments  3 . As the shelving assembly protrusions  22  go through the mating holes  21 , the assembly is then moved toward the side of the van so that the tongue of the base member of the permanent street side frame weldment  3  meets the groove  13  of the base frame weldment  13 A, the tongue and groove mating together and pins  20  being placed through the retaining holes  23  to hold the base frame  12  in place. Similarly, on the curb side, a single base frame  12  with shelving unit attached is mounted. Upon the floor mounting bracket  4 , the six-drawer cabinet  8  is affixed with nut and screw, and upon that the bookshelf  7  also with nut and screw. 
     An alternative embodiment to the pins on chains has the pins  20  affixed to the frame plate weldment with spring tabs so that they would be retainably snapped in and out of place. Also, configurations of more or less six-drawer cabinets or bookshelves and/or a possibility for removing the bulkhead assembly  1  allowing for even more room for the frame weldments towards the front of the van are possible. Within each shelving assembly can be baskets or solid shelves. The legs  14  of the base frame  12  are long enough to place the lowest shelf (the planar surface bounded by the base frame structure) above the height of the rear wheel well of the vehicle.
