SHELVING Filed June 15, 1937 Patented Aug. 27, 1940 asians srmLvrNe poration of illinois Application June l5, 1937, Serial No. 148,258
This invention relates to Shelving and more particularly to supporting clips for use in removably securing the shelves to the upright members.
1t is an object of this invention to provide shelfsupporting clips which may be inserted in assembled relationship with a minimum of effort and which will, not only support the shelves with reh spect to the uprights, but will positively resist transverse displacement in any direction.
il A further object of this invention is to provide a shelf-supporting clip which is particularly useful in connection with sheet metal shelving and bins and which will cooperate with conventional flange constructions.
l5 Another object of this invention is to provide a removable and adjustable shelf-supporting clip which is normally positively secured to the upright members and shelves and is capable of adjustable securement, not only at a variety of fasffo tening stations, but at various positions with respect to each station.
It is an additional object of this invention to provide an adjustable shelf which may be readily clipped into position with respect to upright supi.; ports to provide a shelf which will give additional strength and rigidity to the entire structure.
Numerous other objects and advantages will more fully appear during the course and progress of -the following specification.

Figure 6 is a perspective view of an alternative j form of supporting clip.
:le shelving shown herein for purposes of illustration, comprises upright side members lil and a back upright iii. The sides project forwardly from the rear upright may be supported in 5:; any desirable manner with respect to the floor. Each side upright is provided with a plurality of spaced apertures l for the purpose of permitting vertical adjustment oi the shelves it and similar apertures it for the same purpose are situated ,'35 in linear order on the back upright i2. Similar (Cl. 2lb-136) corresponding rows of openings 2li in the shelf permit rigid attachment of the clips 22.
The preferred form of clip comprises an upper, relatively nat base flange portion Ztl which normally resides adjacent the surface of the asso- 5 oiated shelf and is secured thereto by a bolt 2&3 passing through one oi the apertures 28 and through one of the openings 2o. Adjacent one end thereof is a downwardly depending flange E@ which converges gradually away from the base 10 flange to a point spaced therefrom where'it is bent to form a supporting arm t2. In turn the supporting arm is again bent downwardly and terminates in an outer arm or ange 3d. It will M be seen that the flange 3Q extends from the at-v 15 tachment flange 2li laterally and at a substantial angle. In other words, flange 559 projects downwardly progressing in a direction substantially vertical to the attachment flange 26 so that the arm 32 and the flange 2t are perpendicularly 20 disposed. It is to be noted also that the arm 32 is generally parallel to the attachment flange 24 by which is meant that it extends in the same general direction so that it is capable of passing through one of the openings 2i! in the upright side 25 member lll.
In structures employing the type of clip shown in Figure 5, the line of apertures Ztl adjacent the edge of the shelf is slightly oiset from the corresponding line of apertures lll in the side upright members It a distance equal to half the distance between the apertures 23. In use, therefore, with the shelf maintained generally in position, the end flange tl of the clip is passed through the appropriate aperture in the adjacent upright until the supporting arm 32 rests upon the lower Wall of the aperture and the flange 2li is situated adjacent the lower face of the shelf, as illustrated in Figure 3. The bolt 25 .is then passed through the appropriate opening 28 and the closest aper- 40 ture 2t and tightened to rigidly maintain the assembly at the position shown. The rearmost supporting clips are assembled in the same manner. Here, likewise, the vertical lines of apertures i8 normally reside intermediate the two 45 closest openings il@ in the shelf it. The bolt for fastening the clip to the shelf may, therefore, pass through either or both of the apertures 28. It may be found preferable in assembling the 50 present type of shelf, to rst secure to the rear side of the shelf the three clips (Figure l) corresponding to the three vertical linesoi apertures It, whereupon the three clips may be inserted coincidentally into the proper apertures. As-
sembly is then completed by inserting and bolting the opposed side clips into position.
The alternative preferred type of supporting clip 3G shown in Figures 2 and 6 comprises an upper shelf attaching flange 3G which has a curved or semi-circular periphery. A generally downwardly projecting flange 38 converges to a horizontally bent supporting and torminates in an outer downwardly projecting flange 42. A depressed rib portion lll provides additional strength and resistance against bending and distortion. It Will be seen that the rib i5 extends longitudinally of the supporting arm 32 and continues over a portion of the upright flange In other words, it will be seen from the consideration of the figures that the depressed rib portion is located transversely of the inner section of the supporting arm and the adjacent flange portion extending from the supporting arm to the shelf attachment flange. The apertures in the base flange 24 are three in number and any one or more may accommodate a boli; for attachment to the shelf in the manner described above.
This type of clip may be employed in structures, either where the lines of apertures intersect, or where they are offset in the manner described in connection with the previous embodiment. Thus, for instance, where the front line of apertures 2l] intersects the corresponding vertical lines of apertures lli, it will be preferable to insert the fastening bolt through the central opening 46. On the other hand, where the rear line of apertures 2C as closely :at ghe baci: up*- right l2, or in the event that the vertical line of apertures I3 passes between the nearest apertures in the rearmost line 28, then it will be found more desirable to fasten the bolt through either of the side apertures (i5. As in the previous embodiment, preferably five clips are provided to each shelf. However, as shown in Figure 2, the shelf is preferably supported at each end by two clips engaging apertures in each upright IU. Alternatively only two side clips may be employed with three of the clips engaging in the back upright in the manner shown in Figure 1.
The present invention is particularly useful in the case of sheet metal shelving, especially in connection with shelves which have flanged edge portions. The shelf il in Figure 3, having a flanged edge 138, is bolted to the supporting clip 22 in the manner previously described, the supporting arm 32 of the clip passing through one of the apertures lll in the upright il] (see Figure 3). It will be apparent that the ange 48 is accommodated between the flange Sil and the inner surface of the upright lll. In such a device the elongated apertures 28 in the clip permit adjustment to properly permit the clip to engage and accommodate the shelf flange. Conversely the supporting clip may be reversely positioned on the upper surface of the shelf.
Referring to Figure 4, there is disclosed a sheet metal shelf Eil having a vertically extending edge flange 52. This latter flange in this embodiment is deeper than the adjacent corresponding flange 30 of the clip support wherefore an aperture 54 is provided in the former flange and positioned to accommodate the supporting arm The base flange is bolted to the upper surface of the shelf by means of a bolt 26 with the supporting arm 32 extending through the flange 52 and a suitable aperture in the upright.
The present type of shelf support, not only maintains the shelf in position againstl vertical stresses when heavily loaded, but actually serves to properly space and confer additional rigidity upon the entire assembly. The two vertically extending flange portions of the clip engage opposite surfaces of the upright with which they are associated, thus preventing displacement transversely of the upright and tending to lock all of the vertical members in assembled position. The shelves are, under all circumstances, prevented from being pulled out of position by the outer transverse flanges t2. At the same time the necessary structural resiliency and flexibility is readily permitted. Thus, as the shelf is heavily loaded and deflection occurs, the supporting clips may tend to pivot very slightly about their plane of support in the upright members without tending to distort the remainder of the structure. This is particularly true of the embodiments wherein the supporting clip is positioned below the shelf.
It is thought that the invention and numerous of its attendant advantages will be understood from the foregoing description and it is obvious that numerous changes may be made in the form, construction and arrangement of the several parts without departing from the spirit or scope of the invention, or sacrificing any of its attendant advantages, the form herein described being a preferred embodiment for the purpose of illustrating the invention.
