6 Claims. or. 248-243) This invention relates to an end shelf bracket and more particularly, to a bracket adapted to support a shelf or the 'like upon a single vertical column.

The invention herein generally relates to the type of bracket disclosed in my previously filed application for a Shelf Bracket, Ser. No. 819,894, filed June 12, 1959 whose disclosure is included herein by reference.

The object of this invention is to form a single bracket unit for securely and rigidly supporting a complete shelf upon a single support column and which unit is so formed and so connected to the column that it will not twist or settleto one side even if the supported shelf is loaded ofi balance. The construction herein is particularly useful in supporting an end shelf on one post where a pair of spaced posts are used and a center shelf is supported between the two posts, as described in my abovementioned earlier filed application, and wherein the end shelf may be located in the same plane as the central shelf.

A further object of this invention is to form an end shelf bracket unit that is inexpensive, easily applied and removed and which is rigid and which supports the weight of a shelf in three generally triangularly shaped segments to give maximum support to the opposite ends and the central portion of the shelf.

Another object of this invention is to form a bracket unit that can be easily and quickly applied and removed simply by applying or removing one bolt and then pushing the bracket out of mounted position.

These and other objects of this invention will become apparent upon reading the following description of which the attached drawings form a part.

In these drawings:

Fig. 1 is a top view of a single support column with the end shelf bracket herein secured thereto and with a shelf shown in dotted lines.

Fig. 2 is a view taken in the direction of arrows 22 of Fig. 1 and with the shelf 'shown in cross-section.

Fig. 3 is a perspective view of the end shelf bracket, per se.

Fig. 4 is an enlarged view taken in the direction of arrows 44 of Fig. 1.

The end shelf bracket herein is designed for use with a single vertically arranged column. This column may be one of a pair of columns supporting shelves between them but only one of the pair is used for this shelf bracket.

With reference to Fig. 1, the column which is shown for illustration purposes is generally designated as 10 and is formed of two identical halves 11, each having a tongue 12 and an enlarged head 13 fitted into a groove 14 formed in the opposite half. The two halves may be assembled by sliding their tongues into their respective grooves to thus fonn opposing walls (tongues 12) which are provided with slots 15. These slots are uniformly spaced apart along the length of the column and j p 1 2,97 ,003 Patented Mar. 21, 1961 Vet-members 20 each formed of a single sheet of thin, .rigid, sheet metal, such as thin sheet steel or the like,

and with each being arranged in a vertical plane to present a top horizontal edge. Each of these bracket members are formed with a blade portion 21 and with a connection portion 22. The connection portions are formed of three hooks, spaced one above the other with the top hook being arranged above the height of the top edge of the blade portions and the bottom hook being arranged below the bottom edge of the blade portions.

As can be seen in Fig. 4, each portion 22 is so arranged that its hooks can be slipped through three adjacent slots 15 in its respective tongue or wall 12 and then by being pushed downwardly, its hooks will engage with the bottom edges defining the slots. For removal, the bracket members need only be pressed upwardly to disengage their hooks from the tongues and then by pulling the hooks out through the slots 15 the bracket members are free from the column.

The two bracket members are normally aligned in the same vertical plane and are also horizontally aligned with their connecting portions also being opposed and aligned (see Fig. 3). Their respective-connection portions are spaced apart from each other a short distance to accommodate the space between the pair of tongues or walls 12 of the column.

A pair of identical, elongated strips 30 are provided, each having a joist strip extension 31, a base 32 welded or otherwise permanently secured to the blade 21 of one bracket member, and a fastening extension 33 bent forwardly of one face of the blade 21 and terminating in a flange '34 which is normal to the blade 21. The two flanges 34 are provided with aligned openings through which a bolt or other suitable fastening means may be fitted and secured (see Fig. 1).

'The free ends of the joist strips are connected together by means of a cross member 37 formed of the same material, such as strip metal, as are the strips 30. The cross member may be formed integral with the two strips 31 by welding or other suitable mechanical or both strips and the cross member can be made out of one, continuous piece of strip material.

The top edges of the blades 21, joist strips 31 and cross member 37 are all in the same horizontal plane to support a flat shelf 40. This shelf may be formed of thin sheet metal or the like and is formed to fit over the respective parts of the support bracket with its downwardly depending end flanges 41 fitting over and concealing the support bracket parts. As shown in Fig. 1, a central portion of the shelf may be cut out, as at 43, in order to fit around the column 10.

In operation, the support bracket, which comes fabricated as shown in Fig. 3, is arranged adjacent to the single support column and its two connection portions 22 are sprung apart to fit around the opposite sides of the column and their hooks are then moved into the slots 15. The connection portions 22 may be sprung apart because the bracket, being made of thin metal strip has some inherent springiness in the particular direction re quired, namely in moving the bracket members 20 towards and away from each other. Once the connecting portions 22 are engaged with the Walls 12 of the support column, the fastening extensions '33 will be in front of the column and will engage the sides'of the column and part of the front thereof and their flanges 34 will be adjacent one another. Thus, a bolt 35 may he slipped through the openings in the respectivefianges 34 and by tightening the bolt, the two flanges 34 are drawn together and the extensions 33 are tightly engaged against the column. Thus, the entire shelf support will be accurately horizontally aligned relative to the vertical column and will be rigidly connected to the column.

At this point, the shelf may be simply laid on top of the support bracket and be left there for as long as it is needed. When it is desired to remove the shelf, the shelf is lifted upwards from the support bracket and the bolt 35 is disconnected and then the two bracket members 20 are disengaged from the respective slots 15 in the walls 12 of the column.

With the construction shown, the weightof the shelf, which can be very heavy depending upon what types of articles may be loaded upon the shelf, is supported by generally triangular in shape segments. Thus, the two ends of the shelf are supported by a pair of triangles formed by the blades 21 and the joist strips 31. The central portion of the shelf is supported by the area formed by the two joist strips 31 which area is generally triangu lar in shape. The portion of the shelf that is closely adjacent to the support column is supported by the generally triangular area formed by the extensions 33. Hence, the entire shelf is rigidly supported and even though the shelf may be heavily loaded on one side or one end, this off balance loading will not cause the bracket to twist or dip relative to the horizontal and permit the shelf to bend downwardly from its horizontal position.

This invention may be further developed within the scope of the following attached claims. Accordingly, it is desired that the foregoing description be read as being merely illustrative of an operative embodiment of this invention and not in a strictly limiting sense.
