9 Claims.

This invention relates generally to steel shelving and more particularly to such shelving which is readily assembled and dismantled.

Among the objects herein is the provision of structure, which is quickly and easily set up, requiring no special tools or unusual skill on the part of the person doing the assembling.

Another object of the present invention is the provision of a shelf supporting bracket or clip which is universal in its application, so that one shape or style of clip is suitable for use in any position in the shelving structure.

Another object herein is the provision of knockdown steel shelving in which the parts are adjustable after the shelving has been set up, so that any single shelf in an entire shelving installation may be adjusted in height or removed without disturbing any of the other shelves, Furthermore, when it is desired, additional shelves may be added to shelving installation after same has been originally installed.

Another object herein is the provision of shelf supporting means, which is of relatively great strength in proportion to the weight of the material used.

Another feature of this invention is the provision of a clip for the support of the shelves, which, when in position, presents a very attractive appearance with no undesirable sharp pro jections which may damage material or objects placed upon the shelves. I

Another feature of the present invention is the provision of a detachable shelf supporting clip, which not only supports the shelf vertically, but also supports the shelf in conjunction with the uprights of the shelving installation, so that the shelves are prevented from shifting laterally.

Another object herein is the provision of vertical separating walls which are adapted for cooperation with the shelf supporting clips and the uprights, and may be used between the sections of the shelving as desired,

A feature of the present invention lies in the peculiar construction of the clip, which results in a wedging action as a shelf is placed in position, so that the entire unit is rigid.

An object herein is the provision in the clip structure of means for automatically decentering the clips, so that they are always in the proper position with relation to the upright, and individual clips may be inserted or removed from either side of the upright independently,

These objects and further incidental ends and advantages will more fully appear-in the progress of this disclosure, and as pointed out, in the appended claims.

In the drawings in which similar reference characters denote corresponding out the several views:

Figure 1 is afragmentary isometric view showing a portion of the upright, a portion of the separating wall and two shelf supporting clips in position, just prior to their insertion into a connection with the upright.

Figure 2 is a fragmentary elevational view showing one of the shelf supporting clips in position on the upright with the clip to the rear of the upright,

Figure 3 is a view taken similarly to Figure 2, with the exception that the clip has been rotated through degrees and attached to the opposite side of the upright.

Figure 4 is a fragmentary plan view showing four uprights and portions of three shelves'with the separating walls in place. I

Figure 5 is a fragmentary sectional view as seen from the plane 55 on Figure 4.

Figure 6 is a fragmentary vertical sectional View, as seen from the plane 66 on Figure 4.

Figure '7 is a horizontal sectional view, as seen from the plane 1-] on Figure 6.

As may be readily understood by those familiar with the art to which the present invention relates, shelving installations may be made in any size, depending upon the requirements of the individual installation. A, single shelving unit is made up of four uprights H), II, l2 and I3,

parts throughwhich may be of any suitable height. Since theuprights are of uniform construction, a description of one will suffice for all. Turning now to Figure 1, the upright I0 is provided with a face l4 and a tail portion !5. The uprights may be suitably fabricated from so-called T bar. face I lmay be left as it comes from the mill or may be provided with other decorations, since the outer surface 16 thereof is not used for any functional purpose. vided with a plurality of elongated slots ll, l8, I9, 2B, 2! and 22, hereinafter generally indicated by numeral 23. As shown in Figure 1, the upright ID is broken off at the bottom thereof. However, upright I0 may continue for any suitable distance and have further slots similar to the slots 23, which are placed symmetrically with relation to the above mentioned slots. The size and spacing of the slots 23 will depend upon several considerations, but are essentially deplendent upon the size of the shelf supporting c we The- The tail portion-l5 is pro-.

Since the shelf supporting clips, indicated generally by numeral 25, are all uniform in construction, a description of one will suflice for all. The clip 26 is preferably formed from a single blank, the thickness of which is approximately one-half the width of the slots 23. Clip 26 has a body including a back portion 21 and two forwardly bent flanges 28 and 29. Flange 29 has a laterally off-set portion 38, a small hook 3| and a large hook 32 and a guide 33. Flange 28 has a large hook 34, a guide 35 and a small hook 36. Hooks 3|, 32, 34 and 36 have notches 31, 38, 39 and 48 respectively. Clip 46 has a body including a back portion 41 and two forwardly'bent flanges 48 and 49. Flange 49 has a laterally off-set portion 58, a small hook a large hook 52 and a guide 53. Flange 48 has a large hook 54, a guide 55 and a small hook 56. I-Iooks 5|, 52, 54 and 56 have notches 51, 58, 59 and 68 respectively.

Flanges 28, 29, 48 and 49 are each recessed to H provide horizontal shelf supporting portions 6|, 62, 63 and 64 respectively. Flanges 28, 29, 48 and 49 have shelf gripping portions 65, 66, 61 and 68 respectively. A configuration of the parts just described is best seen in Figure 6, in which it may be seen that the shelf gripping portions 65 to 68 inclusive are angularly disposed at a slight angle with relation to the back portions 2! and 41.

A separating wall I8 is composed of any suitable relatively thin sheet material and is provided with a plurality of elongated slots TI, I8, 1.9, 80, 8| and 82, hereinafter generally indicating by numeral 83. Slots 83 are placed in the separating wall 18, so that they correspond exactly with the slots 23. The slots TI, 19 and 8| are spaced from the leading edge 84 so that when slots I9 and I9 are placed in alignment, the leading edge 84 will lie rearwardly of the rear portion 85 of the face I4. The width of notches 31 to 48 and 51 to 68 is slightly greater than or equal to the combined thickness of the separating wall 18 and the tail portion |5.

The operation of installing the clips 26 and 46 upon the upright I8, as viewed in Figure 1, will now be described. The clip I8 is grasped between the fingers of the operators hand and moved forwardly and to the right, as viewed in Figure 1. Hooks 34, 3|, 36 and 32 will penetrate slots 19, 88, 8| and 82 respectively, and slots I9,

28, 2| and 22 respectively, thereby compressing the separating wall I8 against one side of the tail portion l5. After the clip 26 has been moved all the way to the right, it will be in a position so that the lower edges of the slots 23 and 83 may engage the notches 39, 31, 48 and 38. In other words, the clip 26 is moved downwardly until the edges of said slots will strike the uppermost portions of the notches in said clip. In order to facilitate the operation just described, the entrances to the notches 39, 31, 48 and 38 are rounded. Since the guides 35 and 33 project to the right beyond flanges 28 and 29 and amount equal to the thickness of the blank from which 26 is formed or an amount equal to one half the width of the slots 23 and 83, it may be seen that the clip 26 will be shifted forwardly, as viewed in Figure 1, so that the same will occupy a position substantially that shown in Figure 2. The guides 35 and 33 definitely align theclip 26 with relation to both the separating wall 18 and the upright I8.

The insertion of the clip 46 is performed by movingthe clip to the rear and to the left, as viewed in Figure 1. Here again, the guides 53 and 55 will shift the clip to the right and rearwardly, so that the hook 5| may penetrate the slots I9 and 19, and to the right and rear of the hook 34. By reason of the fact that the hook 5I is a small hook, even when the lower edge thereof rests upon the lower edge of the slot I9, the upper portion of the small hook 5| may pass below the guide 35 and penetrate slot l9 until the flange 49 strikes the near surface of the tail portion I5. What has just been said of small hook 5| is in similar fashion true of small hook 56, with relation to the slot 22 and the large hook 32 and the guide 33. The large hook 52 is moved to the rear and to the right by reason of the guide 53 when the hook 52 is passed through the slots 2| and 8|, and the large hook 52 is of sufilcient height, so that the guide 53 may pass through the slot 2| without interference with the small hook 36. The large hook 54 and the guide 55 act with relation to slots 28 and 88 and small hook 3| in a manner similar to the large hook 52 just described. It may thus be seen that either one of the clips 26 or 48 may be placed upon the upright I8 independently of each other and either of said clips, when in position upon the upright I8, will also hold the separating wall 18 in place. While the clips hold the separating wall 18 against horizontal displacement, said wall may tend to drop so that the upper edges of slots 83 will contact the guides 35 and 55. In order to secure the wall vertically in alignment holes 4| in the wall 18, and holes 42 in the tail portion I5 are provided. An 0rdinary bolt and nut placed in any pair of the aligned holes 4| and 42 will hold the wall I0 in vertical alignment.

Turning now to Figures 4, 5 and 6, the assembly of shelves in connection with uprights upon which clips have already been placed, will be described. Numerals 86, 81 and 88 represent shelves, the edges of which are formed by bending the shelf mattrial around a horizontally disposed reinforcing bar 89. Bar 89 is preferably rectangular in cross-section and continuous. In Figures 5 and 6, the clamping action which occurs between the upper portions of the clips and the uprights to which they are attached, may be readily seen. In the left hand portion of Figure 5 may be seen the offset portion 58, which is clamping shelf edge 98 thereat between said offset portion and the face I4. In the right hand portion of Figure 5 may be seen the flange 28 clamping the shelf edge 9| between said flange and the face 92 of the upright I2.

In Figure 6, the shelf edges 93, 94, 95 and 96 are shown supported by the horizontal shelf supporting portions, previously described. The shelf edges 93 to 96 are clamped between the upper portions of the clips 26 and 46 and the tail portions I5 and 91 of the uprights I8 and I2. By reason of the angular disposition of the shelf gripping portions 65 to 68, as has been previously described, the shelf edges 93 to 96 form a very tight fit and in forcing the shelf edges into place, the shelf gripping portions 65 to 68, together with the adjacent portions of the clip bodies, may be distorted slightly outwardly, as indicated by the dot-dash lines.

As may be readily understood, the clearance of the various parts may be adjusted to give varying degrees of rigidity to the structure and tension between the wedged parts. Where the shelvingunits are to be installed for semi-permanent use, it is desirable to reduce the clearance so that forcing the shelf edges 93 to 96 into place,

may require more than ordinary manualpressure, such as the pressure secured by a jack, screw or hammer. On the other hand, where the shelving is desired to be easily .and quickly demountable, the clearance may be increased between the various parts, so that no unusual pressures are required.

It may now be seen that there has been disclosed a new and effective easily constructed shelving, which is capabl of being quickly assembled, adjusted or dismantled and which possesses many inherent advantages. By reason of the uniform and symmetric spacing of the slots in the uprights and in the separating walls, the cost of manufacturing the tools and their maintenance is reduced. A single clip structur is suitable for use in all positions, and by reason of the peculiar arrangement of the hook members thereon, corresponding hooks of opposite clips occupy the same slots in the uprights and separating walls, novel means being provided for properly aligning each of the hooks within its respective slot with relation to the corresponding hook on the opposite clip, and with relation to the upright and the shelf which the clip supports. Each of the clips is positively supported at four independent points, so that there is no idle portion on any clip. The upper portion of the clip is provided with a novel offset which gives adequate clamping pressure upon a shelf edge which it supports in two different directions 90 degrees apart, and this result is secured regardless of the position of the clip.

The foregoing description has been made rather detailed for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.
