9 Claims.

This invention relates to metal furniture, more particularly to metalshelving units and, among other objectsaims' to provide an improved shelf and supporting elements, including novel posts or uprights to which a series of shelves are adapted to be removably. connected. The main idea is to. provide a very strong and durable construction wherein the shelves can be very quickly and easily assembled and will not sag under relatively heavy loads. Also, the invention contemplates the provision of specially shapeduprights or posts presenting rounded corners which will not damage r an se Otheraims and advantages of the invention will appear in the specification, when considered inconnection with the accompanying drawing, wherein:-

Referring particularly to. the drawing, the improvements are there embodied ina shelving structure of the. type wherein shelf units are adapted to be removably secured to a series of up rights or corner postsby means of supporting clips or brackets. Since shelving of this character may be embodied in metal furniture of many different designs, such asbook sections, merchandise racksytables, etc., it is deemed unnecessary here to disclose a complete structure. However, it will be understood that. the shelves are usually rectangular or square and are supported by four uprights or corner posts.

In Figs. 1 and 2, there is shown a sheet metal shelf l0 which has down-turned side and end marginal flanges lland reversely bent or upturned flanges 12 whose upper edges preferably contact with the lower face of the shelf. The arrangement is such that the flangesprovide very strong reinforcing edges for the shelf and they are spaced. to provide a substantially rectangular channel between them. At the corners, the flanges on one side are shown as being cut away to provide post-receiving notches and corner reinforcing bars 13 are secured between the

flanges

11 and 12, being exposed in the notches. These bars are conveniently madeof strap metal and bent at 14 as shown in Fig, 3 so as to provide for a connection to the corner posts, about to be described.

. While the flanges and reinforcing corner bars may be assembled in any suitable manner, the shelf units are preferably formed on a suitable die and the legs of the reinforcing bars are secured in plaoe'during the die forming operation. This provides a very substantial, rigid construction without necessitating special securing bolts or rivets for the bars. Furthermore, the lengths of the legs of the reinforcing bars are such as to distribute the load transmitted to a corner post over a substantial portion of the shelf, thereby preventing the shelf from sagging at the corner where the bending strain is the greatest.

A shelf unit is here shown as being connected to a specially shaped corner post having folded or rounded edges. In this example, the corner post presents a wide flange or web. portion 15 and a relatively narrow angular flange portion 16, these parts being somewhat similar to an ordinary structural angle. The width of the flange 15 is such as to fit in the cut-away corner portion of the shelf. At the left hand edge of the post, as viewed in Figs. 1', 2and 3, is provided a reversely bent narrow flange 17, which is spaced outwardly from the flange or web 15 so as to provide adequate strength and so that the outer face will lie flush with the outer face of the marginal down-turned flange 11 of the shelf (Fig. 3). At the other edge of the post there is shown a relatively wide reversely bent and rounded flange or molding section 18 having its marginal edge bent rearwardly as viewed in Fig. 3, providing a flange 19 lying in the same plane as the flange 1'7. It will be understood that the

bent flanges

18 and 19 may be variously shaped to correspond with ornamental moldings of different styles. These moldings will ordinarily be arranged at the front of a series of the shelf sections and when several sections are arranged, end-to-end, the molded edges will be adjacent'to each other with the flanges 19 in contact so that one molded edge is complemental to the other. i This will provide a very attractive and ornamental mold of approximately semicircular shape. Moreover, the rounded edges of its 15 of the corner post is shown as having a series of vertical slots 20 suitably spaced to provide for supporting the shelves at diiferent heights, depending upon the size or dimensions of the arti cles to be displayed. Herein, there are three slots in each group or set and they are arranged to provide a three-point support for specially shaped shelf-supporting brackets 21 adapted to be cut and stamped out of sheet metal. One notch is here arranged below the other two. In this example, the brac acts are substantially U-shaped, presenting notched flanges 22 which provide hooks 23 adapted to co-operate with two of the slots 20 in the web 15. A projection 24 is also formed at the lower end of the bracket to cooperate with the lowermost notch in the corner post. The arrangement is such that the brackets may be easily inserted in the notches or slots 20 and slid down into interlocking engagement with their lower edges.

At the upper edge of each bracket, there is shown a bar-engaging flange or arm 25 presenting a shoulder or ledge 26 against which the lower edge of one of the reinforcing bars 13 is adapted to rest. The upper end of the flange is bent slightly outwardly so as to guide the reinforcing bar 13 and hold it against the inner face of the flange or web 15, and the end is bent at right angles to the plane of the web portion of the bracket so as to present a supporting shelf 2'. against which the lower face of the shelf is adapted to rest. Thus, the confining flanges 25 serve the two-fold purpose of preventing displacement of the shelves relative to the corner posts and providing two supporting surfaces for the shelves, as clearly shown in Fig. 4.

If desired, the shelves may be positively locked to the corner posts. For this purpose, the flange 25, the bar 13 and the web 15 present alined openings adapted to receive a pin or rivet 28 (Figs. 2, 3 and 4). It will thus be seen that the rivet prevents the bracket from being lifted out of its slots and disengaged from the post and also holds the shelf in engagement with the bracket flange or clip.

From the foregoing description, it will be seen that the improved shelving elements can be made of standard parts; that the corner posts are so designed that they may be formed by one or more rolling or stamping operations; that the shelves and the brackets or clips can be formed of sheet metal by die-stamping and cutting operations. Furthermore, the reinforcements at the corners of the shelves afford adequate strength to resist bending or sagging under heavy loads. Also, all of the parts can be manufactured very cheaply and can easily be assembled by an unskilled workman.

Obviously, the present invention is not restricted to the particular embodiment thereof herein shown and described. Moreover, it is not indispensable that all the features of the invention be used coniointly, since they may be employed advantageously in various combinations and subcombinations.
