IIIIIIIIIIIIIIII .llllllllsllllllllllllll nllllllllllllllllllll-lllllllll li United States Patent 3,102,641 STORAGE RACK Anthony N. Konstant, Mount Prospect, and Burt E. Schell, In, Long Grove, llL, assignors to Speedrack Inc., Skokie, 111., a corporation of Illinois Filed Dec. 4, 1961, Scr. No. 156,811 8 Claims. (Cl. 211-148) The present invention relates generally to storage means and more particularly to a storage rack or structure which can be adjusted to accommodate packages or articles of various shapes and sizes.

Because of the varying inventories of industrial concerns, storage structures have always been sought which afford maximum flexibility in storage area so as to eleminate wasted storage space by effecting high density storage, i.e., the maximum amount of material in a given space. Since it often is impossible to foresee changing storage requirements, it is desirable that the storage structure be readily adaptable to elliciently accommodate new sizes and shapes of merchandise It is desirable that these adjustments can be made quickly and simply without a complicated and time-consuming knock-down and re building procedure. It is also often desirable for the structure to be one which is self-supporting so as to eliminate any need for placement in a specific type of location in order to attach it to the building for support.

Permanently fixed shelving is inherently incapable of achieving high density storage in an industry with a changing inventory, for wasted space appears as soon as new goods of ditfercnt dimensions must be stored in a fixed bin intended for goods of another size. Storage structures have previously been designed in an attempt to eliminate this wasted space by providing vertical adjustment of storage shelves. However, these adjustments have often entailed time consuming mechanical operations while only partially solving the problem. The present invention provides for both horizontal and vertical adjustments in a manner which can be accomplished quickly and easily without the need for screws, bolts, etc.

Accordingly, the main purpose of the present invention is to provide an improved storage structure which is readily adjustable in order to selectively provide storage bins or compartments of difierent dimensions as needed to accommodate goods of varying shapes and sizes. Another object of the present invention is to provide a structure which is quickly and easily adjustable to new storage requirements with a minimum use of screws, bolts, etc. A further object of the invention to provide a selfsupporting, stable, durable structure constructed of a minimum number of interchangeable parts which can be assembled or disassembled without special tools, allowing placement anywhere and without regard to supplementary supporting structures.

Further objects and advantages of the present invention will be apparent from a study of the following description and accompanying drawings of one preferred embodiment of the invention in which:

FIGURE 6 is a perspective view showing one of the crosspieces which are connected between pairs of opposite posts with a shelf shown in phantom; and

FIGURE 7 is a perspective view showing the interconneotion of an upper beam and a bent.

FIGURE 1 of the drawings illustrates a self-supporting structure which is the basic unit of the invention. It should be understood that although only one pair of frames 11 are shown in the drawing in order to portray the basic unit, the new storage structure may, and preferably does, include a series of any reasonable number of frames 11 spaced apart in a row covering the desired storage area.

The basic supporting structure seen in FIGURE 1 comprises a pair of upright end frames or bents 11 spaced apart and connected together by a pair of upperparallel beams 13 and a pair of lowerparallel beams 15 which are preferably disengageably connected to the bents 11 to form an open rectangular framework. Thebeams 13, 15 contain spacedopenings 17, 19, respectively, along their lengths as can be more clearly seen in FIGURE 2.

Theseopenings 17, 19 permit the selective insertion of pairs of front andrear posts 21 between the upper 13 and lower 15 beams between the upright frames or bents 11. Crosspieces 29 {see FIGURE 6) may be selectively hung on the pairs ofposts 21 by means of thesupport brackets 27 thereon thus providing a base forshelves 33. The bents 11 likewise are provided withsupport brackets 27 to accommodatehorizontal crosspieces 29. The selection of varying horizontal locations for theposts 21 and dilferent heights for thecrosspieces 29 affords a multitude of over-all storage patterns, one of which is illustrated in FIGURE 1.

Each of the upright end frames or bents 11, includes a pair of spaced, front and rear vertically extending columns orchannels 35, a pair ofhorizontal spacing members 37, and two diagonal cross-braces 39 arranged in the shape of an X. Thespacing members 37 and diagonal cross-braces 39 are preferably connected, as by welding, to thevertical channels 35.

Thevertical channels 35 are preferably C-shaped in horizontal cross-section and have a plurality of horizontal pairs ofholes 41 extending through them with the pairs being vertically spaced. The pairs ofholes 41 are also aligned in two vertical rows along both edges of the inside and outside faces of thevertical channels 35. Since vertical adjustment of thebeams 13, 15 is not herein desirable, only the uppermost and lowermost sets of holes need be provided. However, complete rows of holes are provided since they reduce the weight of the structure without materially afiectiug its strength. As shown, only the innermost vertical sets ofholes 41 are necessary for the basic unit structure comprising only two bents 11 shown in FIGURE 1. However, the outermost sets of holes are utilized whenadditional beams 13, 15 are used to add another unit so as to lengthen the storage structure.

Thelower beams 15 are removably connected to the bottom of thevertical channels 35 by any suitable means, such as angle-plates 43 affixed to the ends of thebeams 15 having holes spaced correspondingly to those in thevertical channels 35 through which bolts may be passed to interconnect them.

Theupper beams 13 are releasably held in their endabutting positions to thevertical channels 35 preferably by the structural loci; 61 illustrated in FIGURE 7 and also disclosed in US. Patent No. 2,932,368.

The lock comprises an angle plate 71 and alocking pin 77. The angle plate 71 is affixed to the end of the upper beam preferably by welding and includes twoflanges 72a, 72b which containcammed surfaces 73 and 75, respectively, which are generally perpendicularly disposed in relation to each other. Thelocking pin 77 is releasably held by theholes 41 in thevertical channels 35. When the angle-plate 71 is positioned over thepin 77, downward pressure upon thebeam 13 firmly interconnects thebeam 13 and thevertical channel 35 as thecammed surfaces 73, 75 engage cooperating sections of thelocking pin 77 as illustrated in FIGURE 7.

Thebeams 13, 15 may be of any suitable cross-section, but one having parallel sides is generally preferable. In the preferred construction shown, thebeams 13, 15 are in the form of L-shaped box girders (see FIGURE 2). Thebeams 13, 115 thus provideseats 50 for sheets or sections ofshelving 51 as shown in FIGURE 1, which, by extending between the front and rear beams, serve as a storage base if so desired. The bottom side of thelower beam 15 may be omitted, as shown, thereby saving weight without affecting its function.

The upper surfaces of thelower beams 15 have openings, preferably slots 19, spaced along their lengths at fixed intervals (FIGURE 2.). The slots 19 are of a generally rectangular shape preferably extending transversely of the beam length, and aligned a predescnibed distance from the edges of thebeam 15. The bottom surfaces of theupper beams 13 contain openings, preferably roundholes 17, spaced in a line along their lengths. Theseholes 17 are likewise set apart a fixed interval and arranged so that when thebeams 13, 15 are assembled around hole 17 will be vertically above each slotted opening 19. The line ofholes 17 is a set distance from the edge of thebeam 13 to allow theposts 21 to be accommodated vertically between thebeams 13, 1 5 in any set ofopenings 17, 19.

The intermediatevertical posts 21 in the present embodirnent, as shown in FIGURE 5 are preferably T- shaped in cross-section which has proved satisfactory to give stability and maximum storage area. Thepost 21 is designed to removably fit in a vertically extending position between a pair of upper 13 and lower 15 beams.

A vertically extending tenon, in the present case a circular connectingpin 23, is afiixed atop thepost 21 by any suitable means. In the preferred embodiment illustrated in FIGURE 2, apocket 52 is formed in each of the angle sections so that when they are joined to form the post 21 a socket 54 for thepin 23 is provided. Thepin 23 may be secured in thepost 21 by any suitable means such as welding. The pin 23- has a diameter slightly less than that of theholes 17 in theupper beams 13 so that it can be removably inserted therein.

The T-shaped cross-section of thepost 21 is itself used to form arflat tenon 25. The bottom of thepost 21 is charnfered to leave a section of theweb 59 of the T which will fit into the slots 19 in thebottom beam 15. Thechamfer 60 is fashioned diagonally so that thetenon 25 will fit easily into the slot 19 while the Widest part of the upper end of thetenon 25 is just slightly less than the longer dimension of the slot 19 so as to insure a stable configuration. Thechamfer 60 ends at a shoulder 53 which seats upon the upper surface of thelower beam 15 thereby supporting thepost 21.

The over-all length of theintermediate post 21, excluding that of thepin 23 is slightly less than the vertical distance between the bottom surface of theupper beam 13 and the top surface of thelower beam 15 to provide for easy assembly of thepost 21 in the unit when the upper and lower beams remain fixed in their position.

In assembling the column, the upper tenon or pin 23 is inserted fully into thehole 17 in theupper beam 13 and thelower tenon 25, is poised above its corresponding slot 19 in thelower beam 15. Thepost 21 is then lowered until the shoulder 53 rests upon the top surface of thelower beam 15.Title pin 23 is of a sufficient length so that it still engages thehole 17 thus restraining thepost 21 from horizontal movement in any direction. As thus anchored or located, thepost 21 has its fiat surface, i.e., the cross-bar 57 of the T cross-section, facing outside the storage structure and theweb 59 of the T facing inside and across.

Thepost 21 has, intermediate itsend pieces 23, 25, a plurality of vertically spacedsupport brackets 27. Thebrackets 27 are positioned in two vertically aligned rows, and arranged in pairs one on each side of theweb 59 of thepost 21. The brackets or lugs 27 extend outward at an angle from the vertical surfaces of theweb 59 terminating in a short bend upward forming thesupport pieces 47 which are generally vertical. Thebrackets 27 are easily fashioned by stamping them out of the surface of the web in the forming operation. Thepost 21 is preferably fabricated from two angle pieces which are joined, preferably by welding, to achieve the final T- shape.

Support brackets 27 of the same design as those dc scribed with respect to thepost 21 are similarly punched out of, and spaced along, the side surfaces of thevertical channels 35 of the bents 11, or thebrackets 27 may be formed on a separate strap which can be suitably joined to thevertical channel 35. The over-all spacing is such that when a pair ofposts 21 are inserted opposite each other, one in each side of the structure, thesupport brackets 27 on them will lie in line with each other and in the same horizontal planes as thosesupport brackets 27 on the bents 11. Likewise the fore-and-aft horizontal distance betweensupport brackets 27 at the same vertical level on opposite front andrear posts 21 will equal the horizontal distance between those ondifferent channels 35 of the same bent 11.

The load-carryingcrosspieces 29, employed to support theshelves 33, are preferably angle iron pieces and of a length that will allow them to fit between the inside surfaces of crossbars 57 ofopposite posts 21. The vertical surface of each crosspiece 29 contains twooblong apertures 31 so positioned that they will fit over the support ends 47 of two support brackets .27 on a pair of opposite front andrear posts 21 or onvertical channels 35 of a bent 11. When twocrosspieces 29 are connected facing each other at the same vertical level, their horizontal surfaces provide the base for astorage shelf 33. As seen, the vertical spacing of thebrackets 27 allows connection of thecrosspieces 29 at varying heights thereby facilitating adjustment in storage space heights.

Adjustments in width of storage space can be accomplished by simply removing a pair ofopposite posts 21 and replacing them at a different position along thebeams 13, 15 thus increasing or decreasing the horizontal distance betweencrosspieces 29 as desired.

While the embodiment illustrated in FIGURE 1 usesshelves 33 to provide storage support surfaces, it is understood thatcrosspieces 29 with a greater horizontal wiidtlh could be alone used to store rigid items, thus eliminating the need for ashelf 33. It is also understood that sheeting can be inserted betweenopposite posts 21, or hung from theirsupport brackets 27, if desired, to place a partition between horizontally adjoining storage bins.

The embodiment disclosed herein may be changed or modified without departing from the scope of the invention. As another embodiment of the invention, the round holes 17 may be omitted and an elongated, longitudinally extending slot may be provided in the upper beams 13. Likewise the transversely extending slots 19 may be omitted with an elongated, longitudinally extending slot formed in thelower beams 15 as a substitute. In each such case, thetenons 23, 25 are formed to so fit into such a longitudinally extending slot, which slot has a transverse dimension proportioned to accommodate thetenons 23, 25 and thereby hold theposts 21 against transverse movement. In this embodiment, theposts 21 will be restrained from longitudinal movement by theshelves 33 or, if desired, by longitudinally extending tie-bars connected betweenadjacent posts 21 and betweenposts 21 and thecolumns 35 of the bents l1.
