33 Claims.

This invention relates'to shelving and particularly' to what is'known'as commercial'shelving, which is a rugged, rigid t'ypeof shelving having provision for a number of shelves which may be spaced adjustably thereon;

Among the objects of the present invention is to provide shelving which may be quickly assembled from prefabricated structural shapes, bands and sheet metal parts, and prefabricated shelf clamping meanswhereby various types of units may be quickly'assembled and provided with adjustably placed and rigidly held shelving.

Anotherobject'of the invention resides in providing a new type of shelf supporting and rigidifying'stud and clamping means for holding shelving in assembled position relative to four or .more upright supports constituting the main rugged framework or the shelving.

Yet 'anotherobje'ct of the invention resides in providing stud means and/or shelf clamping means which stud means is capable'o'f a number 'of different functional designs'for holding either a single shelf or a'plurality of' shelves on opposite sides of the corner posts; or which stud means is capable of being demountable from its "oooperative'shelf clamp or riveted thereto.

Yet another object resides in providing a shelf clamp and a fastening stud which cooperate with spaced holes in the uprights and with a hole in the"fastenin'g clamp whereby the depending skirt or'flange of a shelf may be utilized for the's'hel'f to the four'uprights not only in a detachable manner but also" in a :very rigid manner to" provide a' strong com- .mercial'shelving. v

"Yet another object of the invention resides in supporting the rear flange of the shelf from the rear backing plate in such a way that the shelf is supported by a detachable fastening member which is inserted in position from the front of the shelving when the back is not accessible.

Yet another object of the invention resides in providing a construction for providing a stronger supporting portion for the corner of the shelf where it rests upon the shelf clip.

Another object of the invention resides in providing the corners of the shelf with integral -dimples to space the clip from the back to allow insertion of the reinforcing band and also to fill the space and contact the side wall of the clip and rigidify the shelf at the point which is usually occupied by the shelf reinforcing band or angle inconstructions wherein the reinforcing band or nel i snoi s a 4 Yet another'object' of the invention resides in providing integrally formed dimples in the top surface of the shelf immediately back of the vertical face flange of the shelf to hold the shelf reinforcing band or angle in place without the use of other means,

Yet another object of' the invention resides in providing a detachable shelf clip usable in combination with a stud adapted tobe inserted in one of a number of spaced holes drilled or punched in the corner uprights or posts of the shelving wherein the clip is provided with a keyhole slot, the stop portion of which is preferably at the bottom of the slot, the clip having side flanges for properly positioning the clip onto one of the flanges of the corner post, said clip having embossrnents for clamping the shelf flange or skirt tightly to the flange of the corner post and having embossments for reinforcing the clip around the stud head that fits into the key slots of the clip. 7

Still another obje ct of the invention resides in providing a stud having a number of different conformations for different purposes of fastening and also for providing a shelf clamping clip for cooperative use with one or the other of the different typesof studs, both the stud and the clip being capable of use in rigidly fastening and clamping or looking the flange of the shelving to the flanges of the corner posts or uprights whereby a very quick assembly and very quick demountability of the shelving from the corner posts when the shelves are loaded with relatively heavy materials the load is supported on the uprightsor corner posts.

Referring now to the drawings in detail, the invention is shown as comprising, for any particular unit 0f shelving, four corner posts or uprights 2, 4, 6 and 8, preferably in cross section of T design. Where two units are to be used, as shown in Figure 1, two additional corner posts it} and I2 are provided. In the preferred constructioneach one of these corner posts is a substantially rugged angle iron ofT-shaped cross section and adjacent corner posts are arranged .so that the legs or central web portions I 4 of each ,T post are facing and confronting each other and are arranged, in a common vertical plane. As shown in Figure 1 the flat T portions l6 and it .of each corner post are arranged in parallelism at .back and front respectively.v The central web portion I 4 of each T-shaped angle ironis provided with a longitudinally disposed series of spaced apart holes20 to receive studs as hereinafter disclosed. In addition, when the shelving is used to support moderate loads, means, is provided for bracing the end pair of corner posts which comprises two elongated straps 22 and 24 which are riveted together centrally as at 26. These straps are thus formedin X-shaped formaview showing a section of the tion and have their outer ends bolted as at 28, 29 and 3|, said bolts passing through the vertical openings 20 of the vertical corner posts whereby to further rigidity these two corner posts. The

opposite end is likewise braced, the bolts passing through selected ones of the holes 20in the web portion M of the T-shaped corner posts.

Each of the commercial shelving units comprises'a top 30 of sheet metal and a plurality of shelves 32, 34 and 36. One of the shelves 32 is shown in perspective in Figure 10 of the drawings. In addition, in certain-desirable instances the shelving is provided with, a sheet metal back 38, see Figures 1 and 12, which back is provided with four vertical series or rowsof spaced apart, elongated holes, each of the outer rows such as 4 50 and 52 being preferably arranged near the vertical edges of the back and the third and fourth intermediate rows 54 and 55 being evenly spaced or arranged centrally vertically of the back. The vertical edges of this back are clamped between the inside vertical flanges 56 and 58 of the corner post and the top 30, hereinafter mentioned, and screws, preferably selfthreading. screws 60 pass through the topmost one of the vertical holes and, through the top flange, and in addition a screw will pass through any one of the outside vertical rows such as 50 and 52 and through a corresponding hole in the vertical rear flange of a shelving member when particularly positioned with respect to the vertical rows of holes 50 and 52 whereby rigidly to hold the back in position. The central row of holes in the back is provided to receive a supportin clip or screw, as will be later described, for supporting the rear flange of the shelf intermediate its central portion.

Each shelf 'member 32 is formed of desired gauge sheet metal and is provided with depending flanges, there being a front flange 66, a rear flange 68, and two end flanges I0 and 72. The flanges are formed integrally with the top of the shelving and the top is provided with a series of holes '14 arranged in substantially rectangular spaced formation, a shown in Figure 10, for the reception of partition fastening means. At the corners the depending flanges are provided with overlapping extensions. For instance the front flange 66 and the rear flange 68 are provided with extensions 15 and 16, respectively, which are bent angularly with respect to the plane of the front and rear flanges 66 and 68 and these flanges underlie the ends of the side flanges l0 and 12, being suitably welded thereto whereby to provide at the corners a rugged construction, of double thickness. Each top flange 66, 68, 10 and 12 is provided with an integral, inwardly and upwardly projecting extension 18 for the front, Bil for the back, and 82 and 84 for the two end extensions of the end flanges. In addition the front and rear flanges are provided with four screw openings 86. Relatively close to the end depending flanges 10 and 12 at front and back, the front and rear flanges BBand 68 are provided with inwardly depressed, integral dimples 92, see Figuresll and 15, which are placed so that the bottom portions of these dimples are relatively close to the plane of the vertical side wall of the end flanges 10 and 12, and these dimples are positioned substantially midway of the height of the front and rear flanges 65 and 68. In addition the top of each shelving is provided along the front and rear walls with downwardly bent integral dimples I00 and 12, see Figures 10, 11 and 12.

In certain instances the front and rear flanges 66 and 68 are reinforced by a band or angle or strap'such as I04, see Figures 11, 12 and 15, which is confined between the upturned lip of the depending skirt 68. or in the case of the front flange, the skirt B6 and the metal of the flat top 32. It will be noticed that the dimples 102 are placed as indicated in Figure 12 so that they hold this band or angle I04 in position. The opposite ends of this band, angle or strap I04 are provided with apertures or notches I 06 at the opposite end thereof and also with additional apertures I08} see Figure 15. The apertures I08 register with screws I II which may be used to secure the rear flange 68 of a shelf in position when the clips shown in Figure 14v are not used.

scorers These screws III will be screwed through openings in the back 38, thence through registering openings in the rear depending flange 68 of the shelf and thence through the holes I98 in the bands Ills when the bands are used. The apertures Its shown in Figures 11 and 15 are formed so that they span the dimples'92. It is to be understood that instead of using the hole I06 the ends of the band I34 may be slotted out 'to provide notches. The purpose of these dimples and the holes or notches H16 is shown more clearly in Figure 15. It is understood, of course, that the band I8 3 may be an angle, in which case the flange of the angle would be notched or would be provided with a hole, whichever is preferable. By reference to Figure 15 it will be seen that where the band IE4 is utilized for reinforcing and rigidifying the shelf, sumcient room must be allowed and maintained between the adjacent wall or face III of the clip I10 and the inner wall of the depending flange 68 of the shelf. To this end the dimple 92 is made of sufficient depth so that when the rear skirt or flange 68 of the shelf is juxtaposed against the front or inner wall of the back as shown in Figure 15, the dimple 92 will lie adjacent and practically incontact with the inner wall Ill of the clip IIll which has been placed in position as shown in Figures 5 and 6. Therefore this dimple will 'fill this space, and, in short, will provide sufficient space between the inner wall Ill of the clip I and the inner wall of the flange B8 of the shelf so that the reinforcing or rigidifying band I04 can be inserted in the flange. This dimple contacting the inner wall III of the rigidly mounted clip III! will thus push the rear flange 63' of the shelf rearwardly snugly against the back wall '38 and will allow room for the insertion of the band Hit. Thus when we place the shelf in position and the band its in position within the rear skirt of the shelf, the holes I53 merely span the dimples fl and thus allow the band to be placed in position, and at the same time provide a certain rigidity in the corners of the shelving due to the dimple lying between the rigid inner wall III of the clip lid and the back wall 38, see Figures 4, 5, 6 and 15, particularly Figures 4 and 15.

As shown in Figure 16 the front strap. band or angle I85 is provided with a hole III) registering with the screw I I2 that secures the label holder III; to the front flange 66 of the shelf or to the back 33. When access may be had to the rear wall of the backtB of the shelving, self-tapping screws III, as shown in Figure 15, are used for holding the rear flange SSof-the shelf rigidly in position. These screws I pass through preformed openings in the back and thence through openings formed in therear skirt $8 of the shelving and thence through preformed openings IE8 in the band I04, as shown in Figure 15. When access cannot be had toithe 'rear wall of the cabinet, as for instance when the shelving is backed up against a wall "or when two shelvings are b ack to back, thenythe clip's shown in Figure 14 are utilized for supporting the rear flange of the shelf in the manner shown in Figures 12 and 13, referenceto which will be hereinafter made.

Means is provided for clamping the shelves adjustably in position with respect to the corner uprights. This means comprises spaced holes in the central web of the'upright; the studs which are shown in Figures 5, 6, 7 and 8, and

the clips shown in Figure 9. In Figured one of the studs isshown as comprising a-centralround'barrel-like portion H6 having at one end a cap H8 of larger diameter; the opposite end ofthe central barrel-like portion is provided with a neck IZIl of smaller diameter which terminates in a cap I22 somewhat of the shape of the cap H8 but of smaller diameter than the cap II8 but of larger diameter than the neck I29. This stud is shown as positioned in one of the holes 2Il'of the portion I4 of the post.

In Figure '7 I have shown another form of stud which comprises the central round barrellike portion I24 positioned in a hole 20, a cap portion I26 of larger diameter connected to the portion I2 l which cap portion merges into a neck I28 of smaller diameter and which in turn terminates in a second cap portion I33 which is of larger diameter than the neck portion I28 but of smaller diameter than the cap portion I29. The cap portion ISO is of smaller diameter and construction to the cap I22 of the stud shown in Figure 8.

In addition, the outer end of the roundbarrel I25 terminates in a second neck I32 which in iarneter is substantially the same as that of the neck portion I28 and this neck portion I32 in turn terminates in a third cap portion I34 which issirnilar in size and construction to the opposite terminal cap portion I38. Figure 5 shows this same type of stud.

The studs shown in Figure, 6 are the same as that shown in Figure '7 except that in place of the cap I38 the end of the stud is provided with a rivet I38 by which the stud is affixed integrally to a hole I38 in a clip I40 so that this clip I46 and the stud are fixed together. This stud has a cap portion M2, a round barrel portion I44, a neck portion I46 and an oppositelydisposed neck portion I48 terminating in a second cap use. Thus in this construction the clip I40 carries the stud and the neck portion I48 is adapted to carry another clip I52. It is understood that there are a number of these clips I52 and there may be a number of the special clips I45} carrying studs. In most instances the clips and studs are separable. The studs are preferably formed of metal and are made in any-desired manner.

It is to be understood that the studs are in serted through the registering holes in each web I4 of the four corner posts so that the studs will all be in a common plane with relation to the vertical series of holes 20 in the upright corner posts 2, s, 6 and 8. The large keyhole clips are then inserted through the inwardly projecting ends of these studs so that the clips are in position such that the necks of the studs register with the enlarged portions I54 of the keyhole slots. The clips are then pushed down on the shanks or necks I24 of the studs so that the clips enter the narrow portion I52 of the slots, which means that the clips are then rigidly affixed to the uprights as shown clearly Figures 4, 5, 6 and '7.

The clips are shown in perspective in Figure 9. They comprise two opposed flanges I5 3 and Ifit, the undersides of which lie in a common plane which is in the plane of the portion I58 of the flange I56. The metal of the clip is bowed or formed outwardly from the flanges I56 and let as at its, see Figure 7, and a keyhole I62 is formed in this bowed or lateral portion I60. The wider portion I64 of the keyhole is preferably at the bottom of the slot; The end of this round portion ltd is preferably embossed as at I56 not only to lend'strength-to the clip at the keyhole but also to provide a; stopwhen it is desired to remove the clip from the stud. If this little projection or stop I66 were not there, the end of the round portion of the keyhole slot would project under the shoulder of the head I30 and would lock itself-under this shoulder. However with the embossment I 66 present, as shown particularly in Figure 8, the shoulder strikes the embossment and therefore prevents the edge of the round portion I64 from looking under this shoulder. In other words, the metal at the base of the hole I 66 is struck up at the embossment and therefore cannot underride the shoulder on that part of the stud and therefore it will permit the clip to come freely away from the stud. In addition, the sldes'of the front portion of the keyhole slot, just wherethe narrower portion I62 joins the wider portion I64 are provided with the two, or opposed, indentations I63 and I65. These indentations are provided to lead the clip or cam behind the shoulder of the stud. These relieved corner portions I63 and I65 of the upper edges or the parallel sides of the narrower portion I62 of the keyhole slot of the clip will enable the clip to ease in behind the shoulder of the studs and not to catch on the sharp edge. Hence these indentations lead the studs into the narrower upper walls of the slot as the clip is pushed down from a position such that the shank I24, see Figure 4, moves from the larger hole I64 of the clip into the relatively narrower neck portion I62 of the clip, In addition, the bowed portion of the clip at the end opposite the embossed portion I66 is embossed upwardly as at I68 and I16, see Figure 9, to provide rigidity and to provide a downwardly sloping cam face.I12 terminating in a lip I14. The sides of this face I12 are bent substantially at right angles to provide underneath parallel cam edges I16 which are curved as shown clearly in Figure 8 to provide a progressive wedging action. The high point of this progressive curve is adjacent the outermost edge I14 of this projection I12.

After the four studs have been placed in the appropriate holes in the four corner posts or uprights; the shelf is placed in position between the four posts and the vertical side flanges carrying the double thickness portion such as 84, see Figures 6, 8, and 10', are inserted over the toes I14 of the vertically placed clips and between the progressively wedging surfaces I16 and the web I4 of the uprights. The top corners of the shelf are then forced down by placing a board on the corner and striking with a mallet or pushing down forcibly in any other manner whereby to force or wedge the thickened corners past the cam-like surfaces I16 of the clips whereby the shelf is now rigidly held at its four corners and the shelf in turn assists in rigidifying the four corner posts.

As shown in Figure 5, two of such shelves 32 or two tops 36 may be held-side by side in position with respect to a common web portion I4 of a pair of upright postsby inserting the round portion I24- ofthe stud into the hole 26 of the upright and thence placing the thickened-end flanges of the two shelves 32 between the webs I4 and the tongues I12 of the clips, and then by moving the shelves 32 downwardly, the clips will have their smaller openings I62 surrounding the neck portions I28 and I32 of the studs, the curved wedge-like tongues I 16 of the clips grippingly engaging the reinforced thickened flanges 84 and 82 of the top or of a shelf, whereby simultaneouslyto lock two of the clips and the two shelves to a common upright by means of one combination stud and two clips.

By reference to Figure '1 it will be noted that the head portion I6 of a web portion I4 has an arcuate corner or junction I19 which receives the ends of the flanges I56 and I54.

By means of the foregoing action the shelves are wedgingly and demountably held to the uprights in any adjustably disposed position, depending upon' into which holes the studs are placed, thereafter the studs in combination with the clamps and the flanges of the shelves, or the top, hold such shelves or top firmly and rigidly in position with respect to the shelving.

It is also desirable to support the rear longitudinaledges of the shelves intermediate the ends of the shelves. Where the rear face of the back member 38 is accessible this is accomplished by means of a screw III, see Figure 15. However when the rear face of the back wall 38 is not accessible then it is desirable to support the rear wall of the shelf by means of the rear shelf clip, or shelf-to-back clip shown at I86 in Figure 14. This clip can be inserted from the front of the shelving. I

This clip I86 has stamped as at I62 a rearwardly outwardly and downwardly extending tongue I84 and also an upper tongue I86 which is narrowed to provide a backwardly bent neck I86 and a substantially larger fan-shaped head I88 bent rearwardly of the plane of the portion I86. -At'the bottom the clip I86 is bent forwardly and upwardly as at I96 to provide a tongue I92 which preferably at its tip as at I94 has a slight 1 bend. As shown in Figure 13, by inserting, from the front of the shelving, the fan-shaped head I88 through'the elongated slot 46, see Figure 12, with the head projecting therethrough and lying flat against the rear wall of the back 38 and with the front wall of the clip I86 lying flat against the front wall of the plate 38, said wall will depend downwardly beneath the flange 86 of the depending skirt, will pass therearound whereby to form a cradle to receive the inwardly bent flange 86 of the rear depending skirt of the shelf 32.

In addition to the foregoing, a plurality of partition plates or dividers 266, flanged at top and bottom, are disposed between the top and the next adjacent shelf or bottom to adjacent shelves for subdividing the space between shelves. These dividing plates have, as before noted, upper and lower flanges which extend outwardly at right angles and are provided with holes to register with the holes I86 formed in the top. The construction of the means for holding these dividers'in'posision forms the subject matter of a separate application.

In instances where open-ended shelving is utilized and where relatively heavy objects are going to be supported on the shelves, it is desir able to support'the shelving in such a manner thatithe load will be carried directly by the up rights themselves. To this end there is provided the'cross brace andshelf end support shown in Figures17, 18, 19 and'20. This comprises a vertically disposed sheet metal strap 262 which extends from a point flush with the upper edge of the depending flange 18 of the top of the shelving to a point 264which is short of the floor. This strap 262 extends parallel with the corner posts 2 and 4-andlies vertically intermediate these corner posts. The strap is provided with a vertical series of spaced holes 206. The top portion of the strap is secured by a self-tapping screw'or by a bolt- 208 that passes through a hole 21!] inthe, vertical and flange 19 of the top. The bolt is secured by a nut 212 In addition there is provided a rectangular sheet metal plate 2H5 having the four holes 2l 6 and 218 at its corners whereby four relatively shorter and narrower straps 2,20, 222-, 224' and 22-6 are riveted as at 2,28, 230, 2,32 and 234. Each one of these straps at its outer end is, laterally offset as at 236 and 238 and the ends of such offset portions are apertured to. receive self-tapping screws or bolts 2st and 242 which en'gageany one of the holes 2b in the uprights 2,, 4 and 6., By means of this construction it will be seen that the vertical hand does not touch'the floor, the four short straps 220 to 226 are riveted to the center plate and the. vertical band is, bolted to the center plate as at 244,. The ends of the four short straps extending from the center plate are bolted to the upright T posts, the two uppermost straps being bolted to the uppe mos parts of the T posts. as near the top of he p s as p s and then when the two lower bands are also bolted to the upright Ts, the unit then acts as a cross, brace as well as a unit on which the vertical' band hangs. Finally, when the shelf ends are bolted to the vertical band 202 as at 2%, and the shelves are loaded with material, this load is supported because the vertical band and the two upper bands are put under tension whereby the load is finally supported on the upright corner posts or Tsv 2, 4, 6. and 8. This end brace is used only in open type shelving. When closed or bin type shelving is desired a metal sheet filling the space between the Ts is used instead.

Obviously the invention is not limited to the specific details of construction disclosed herein but is capable of other modifications and changes without departing from the spirit and scope of the appended claims.
