SHELVING STRUCTURE Filed June 13, 1962 I 2 Sheets-Sheet 1 INVENTOR. Payer 4744/19 A TTORNE YS United States Patent 3,143,988 SlmLVlNG STRUTURE Robert J. Evans, Aurora, 111., assignor to Aurora Equipment Company, Aurora, 111., a corporation of Illinois Filed June 13, 1962, Ser. No. 202,282 11 Claims. (Cl. 103144) The present invention relates generally to a shelf or shelving structure. More particularly, the present invention concerns a new and improved post construction as well as a new and improved technique for mounting shelves on the posts.

In the past, it has been the practice to mount shelves on posts by means of locking keys such as shown in the US. Patent Nos. 2,675,287 and 2,824,775. More re cently, in order to reduce manufacturing costs, efforts have been made to eliminate the use of keys, at least in some types of shelving structures. It has been found that the locking keys may be eliminated where shelf supporting embossments are formed directly on the shelf posts from the material of the posts for supporting shelves thereon.

It has further been found that the provision of embossments on angular type posts disposed at the four corners of the shelving structure has certain undesirable features in that it has been necessary to tilt the shelves with respect to the angular posts in order to mount the shelves on the posts and to remove the shelves from the posts. Where it is necessary to tilt the shelves to mount or remove them, the shelves cannot be disposed as closely together and the embossments must be spaced a greater distance apart in order to provide sufl'icient clearance for the shelves to be tilted.

According to the present invention, a new and improved post construction has been developed which enables the shelves to be mounted on the post embossments without having to tilt the shelves when mounting or removing the shelves on or from the posts. Important advantages are gained through the use of the new and improved post construction and shelf mounting technique as the post embossments can be located more closely together and the shelves can be mounted more closely together where desired. 7

Accordingly, an important object of this invention is to provide a new and improved shelving post.

Still another object of this invention is to provide a new and improved means for mounting a shelf on shelf supporting posts.

Yet another object of this invention is to provide a new and improved shelf structure where the components can be assembled without the use of locking keys whereby the manufacturing costs may be reduced.

Another and still further object of this invention is to provide a new and improved shelving structure having posts with embossments on each side so that shelves may be supported from both sides of the posts to minimize the post expense in shelving structure and to permit usage of a maximum amount of shelf area per square foot of floor area.

An important feature of this invention is to provide shelf supporting means where the posts and the shelves are wedged more tightly in assembly together as the load on the shelf is increased.

According to still other important features of the present invention, the posts are each provided with vertically spaced pairs of embossments and the embossments are out free of the posts except along inclined shelf edge support embossment portions and the shelf is provided with inclined shelf edges for wedged engagement there with.

As shown on the drawings:

The reference numeral 10 indicates generally a shelf structure. The shelf structure has four corner posts 11 that embody important features of the present invention. The posts 11 are all identical in construction. Disposed between the posts and secured in assembly with the posts are a series of vertically spaced rectangular shelves indicated generally at 12.

The shelves 12 are identical to one another and a description of one of them will suflice the other. The shelf 12 includes a main shelf panel portion 13 as well as underturned marginal shelf flanges or portions 14 and inturned reinforcing shelf flanges or portion 15. The flanges 15 are inturned from the flanges 14. Adjacent the corners of the rectangular shelf the underturned and inturned

marginal shelf portions

14 and 15 are cut away to provide recessed areas 16 which recessed areas each in elude a pair of confronting inclined edges 17. The edges 17 are inclined in a direction toward the main panel portion 13 for engagement with embossments 18 on the posts 11.

The posts 11 are of a hollow construction and manu factured from a single piece of material which is rolled to shape. The posts 11 each include an attachment post leg 11a, a first inclined post leg 11b, a flat embossment bearing post leg 110, a spacer post leg 11d, a second embossment bearing post leg 11c and a terminal inclined post leg 11f having a tip end engaged in endwise relation against the inclined post leg 11b. Pairs or sets of the embossments 18 are vertically spaced along the lengths of the post legs 11c and 112. Each of the embossments 18 are formed in such a way that only a single inclined shelf edge supporting portion 18a is left integral with the associated post legs or 112. In other words, the em-.. bossment is cut away from the post leg except at its integral juncture 11g with the leg which juncture is located at the area of the portion 18a. The embossment further includes an embossment flap or leg 18b for lapping engagement to hold the flange 14 in snug contact with the post leg 112.

It has been found that the vertically spaced pairs of embossments 18 may be spaced as little as 1 /2 inches apart where the shelf structure is provided with new types. of posts 11 which are disclosed herein. Where angular posts are provided at the four corners of the shelf structure, it has been found that the sets or pairs of embossments must be spaced about nine inches apart in order to provide ample working area for the shelf to be tilted as it is mounted in a horizontal plane between the angular posts. Where posts of the type indicated at 11 are employed, the shelves 12 can be moved in a horizontal plane with respect to the posts in assembling and disassembling the shelves with the embossments 18. When the shelf 12 is disposed between the four posts 11 with the recessed areas in vertical alignment with the pairs of embossments on the posts 11, the shelf can be moved downwardly so that the inclined edges 17 are engaged with the inclined shelf edge supporting portion 18a.

The post construction and shelf mounting arrangement is particularly advantageous for it is no longer necesto tilt the shelf in order to mount the shelf on the posts or remove the shelf from the posts. Thus, the shelves 12 can be spaced more closely and through a more selective range than formerly.

An important advantage of the instant construction is that the heavier the load carried by the shelf the tighter the fit between the inclined shelf edges 17 with the inclined shelf edge supporting portions 18a. In other words, where the shelf load is increased, the inclined shelf edges are wedged more tightly against the shelf edges supporting portions 18a.

Each of the posts 11 can be provided with embossments 18 on its opposite flange portions 11c and He so that shelves may be mounted on opposite sides of the same pair of posts 11. This construction is advantageous in reducing the cost of multiple shelf structures for the number of posts may be kept to a minimum and further since the space required for an extra pair of posts is eliminated permitting a maximum amount of shelf area per square foot of floor area.

In order to reinforce the corners of the shelf 12, the underturned flanges 14 are provided with inwardly angled triangularly shaped metal folds 20. If desired, however, the folds 20 may be eliminated and the flanges 14 may be welded together at the corners.

At the ends of the shelf structure 10, each pair of posts 11 are joined together by end closure panels 21 which are welded at 22 (FIGURE 3) to attach to post legs 11a in assembly therewith. The panels 21 may be bolted or secured by clips at 22 to secure the legs to the panels, if desired.

FIGURES 5, 6 and 7 indicate a modified form of my shelf structure Primed reference numerals have been employed to designate parts which are similar to those parts already described in connection with the shelf structure 10. In this instance, a pair of angular posts 11 are disposed at the rear of the shelf structure 10 and rearwardly of posts of the type indicated at 11 in FIGURE 1. In other words, it is contemplated that posts identical to the posts 11 be provided at the front edge of the shelving structure 10 as was employed on the shelving structure 10. If angular posts similar to posts 11' were provided both at the back corners as well as the front corners of the shelf 12, vertically spaced pairs or sets of embossments 18' could not be spaced as close together as desired, for it would be necessary to tilt the shelf 12' in order to mount the shelf on the angular posts such as indicated at 11'. It will therefore be appreciated that angular posts 11 can be employed at the rear of the shelf structure so long as posts of the type indicated at 11 are disposed at the front edge of the shelf structure 16. By constructing the shelf structure 11' in this manner, the embossments 18' may be spaced closely together and the shelves can be moved directly inwardly in a horizontal plane and downwardly into assembly with the embossments 18 Without having to tilt the shelf 12'.

It will be noted each embossment 18' in each pair or set is disposed in angular relation with respect to one another and carried by angular post legs 24 and 25. The embossments 18 carried by the post legs 24 and 25 are slightly different than the embossments 18 on the posts 11 in that shelf supporting portions 18a are inclined and diverge in a direction away from the main panel portion 13'. The embossments 18' further include embossment legs 18b for lapping engagement with flange 14 to hold the flanges 14 in snug engagement with the post legs 24 and 25 on the post 11'.

The shelf 12 is identical to the shelf 12 except that recessed areas 16' are provided on the underturned flanges 14' on opposite sides of their corner juncture or an opposite sides of flap 20'. If the load on the shelf 12' is increased, the shelf edges 17 are wedged more tightly against the shelf edge supporting portions 18a.

In FIGURE 7, a metal shelf blank 40 is illustratd in full and dotted lines, the dotted lines indicating where the metal is folded in order to form the shelf 12. To this end, the blank 40 is initially cut in order to recess and cut away portions of the blank 40 at its four corners, as indicated at 41 in the formation of the shelf recessed area 16'. The dotted lines 4249 show where the blank is folded in the formation of the flanges 14 and 15'. At the corners of the blank 40, the dotted lines 50-53 indicate diagonal fold lines where the blank is folded in the formation of the reinforcing folds 20'. It will thus be perceived how the shelf 12' can be manufactured from a single piece of stock.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.
