E. F. H ETAL ARTICLE OF FURNITURE Filed May 16, 19s:

IN TOR.

lllll United States Patent 3,187,693 ARTICLE 6F FURNITURE Earl F. Hamilton and Edwin K. Moore, Qniurnhus, 12121., assignors to Hamilton Cosco, 1nd, Qelumbns, End, a corporation of Indiana Filed May 16, 1963, Ser. No. 23%,969 4 Claims. ((11. 108-153) This invention relates to an article of furniture, and more particularly to a leg mounting for a shelf or the like for an article of furniture.

It is an object of this invention to provide such a leg mounting which can be economically manufactured largely from sheet-metal components, which will provide a rigid interconnection between a leg and a shelf or the like, and which can be easily and quickly assembled thereby lending itself to storage and shipment in a compact knocked-down position.

In accordance with the preferred form of the invention as it is embodied in a shelf structure, there i provided a shelf having angularly disposed edges forming the shelf corners at their junctures. The edges of the shelf are bordered by skirts normal to the plane of the shelf and provided with inwardly rolled beads along their lower edges. The shelf and skirt are ofiset inwardly at each shelf corner to form a recessed mounting seat for a ground-engaging leg.

A bracket is provided at each mounting seat and comprises a pair of angularly disposed arms received against the inner face of the skirt stretches extending along a pair of adjacent shelf edges. The bracket arm have means engageable with the skirt beads for releasably mounting the bracket on the shelf at the mounting seat. Fastening means extend through aligned openings in the bracket and leg for rigidly mounting the leg on the shelf and rigidly interconnecting said bracket to the shelf.

Other objects and features of the invention will become apparent from the more detailed description which follows and from the accompanying drawing, in which:

FIG. 1 is a perspective view of a shelf structure embodying the invention;

FIG. 2 is an enlarged fragmentary plan view of the shelf structure shown in FIG. 1 with portions thereof being broken away;

FIG. 3 is a vertical section taken on the line 3-3 of FIG. 2;

PEG. 4 is a vertical section taken on the line 4-4 of FIG. 2; and

FIG. 5 is an isometric view of the mounting bracket shown in FIG. 2.

The invention is illustrated in the drawings as embodied in a shelf tructure comprising a pair of shelves 1% mounted in vertically spaced relationship on a plurality of ground-engaging legs 12 conveniently formed from lengths of metal-tubing and having their ends closed by end caps 14. Conveniently, each of the shelves is formed from sheet-metal and comprises an upper supporting surface 15 terminating at the shelf edges in skirts 16 and 17 extending substantially continuously around the shelf. The lower ends of the skirts 16 and 17 are rolled inwardly to form beads 13 and 19 whose edges are spaced from their respective skirts. As shown in FIG. 2, the shelf edges are angularly oriented with respect to each other to thus define the shelf corners at their junctures where the legs 12 are mounted.

The helf is offset inwardly at its corners to provide recessed mounting seats for connection to the legs 12. To this end, a section of surface is removed and the skirts terminate inwardly from the shelf corners. A mounting bracket 29 is provided at each shelf corner and comprises a pair of arms 22 and 23 which are angularly disposed to each other for engagement with the inner 3,187,693 Patented June 8, 1965 "ice face of the skirts 16 and 17 adjacent the shelf corner. At their adjacent ends, the bracket arms 22 and 23 are bent inwardly at right angles to each other, as at 24, so that when said bracket is mounted in one of the shelf corners, the arm portion 24 lies in the vertical plane of the inwardly offset edge of the shelf supporting surface 15 to abut a pair of adjacent walls on the leg 12 in face-to-face contact. Conveniently, a pair of bosses 25 are formed on the portion 24 to strengthen the bracket 20.

In order to releasably mount the bracket 21 on the shelf 19, downwardly projecting fingers 27 and 28 are formed on the bracket arms 23 and 22, respectively. Thus, to mount the bracket 2% on the shelf 10, the finger 27 is inserted in the space between the bead 19 and skirt 17 along one side of the shelf, and the skirt 17 is stressed inwardly to dispose the bracket finger 28 in alignment with a notch 39 cut in the bead 18 on the skirt 15. When such a stressing force is released, the skirt 17 will again spring outwardly clue to its inherent resiliency to dispose the bracket finger 28 out of alignment with the notch 30 to thus releasably retain the finger 23 between the skirt 16 and the bead 18 for releasably retaining the bracket on the shelf. A pair of lugs 32 and 33 project out of the general plane of the bracket arms 23 and 22, respectively, and engage the upper faces of the beads 19 and 18. The distance between the lower faces of the lugs 32 and 33 and the upper edges of the bracket arms 22 and 23 i smaller than the distance between the upper edges of the bracket arms and the lower edges of the fingers 27 and 23 to thus prevent the fingers 27 and 23 from pulling out of the beads 13 and 19.

The leg 12 is mounted on the shelf by disposing a pair of its adjacent wall surfaces in the mounting seat formed in the shelf against the bracket arm portion 24. A bolt 3a i then inserted through aligned openings in the leg 12 and an opening 33 in the bracket 20 disposed in alignment with the leg openings. The bolt 36 projects through the bracket opening 38 for the reception of a nut 49. As shown in FIG. 2, upon tightening of the nut 49 on the bolt 36, said nut will bear against the bracket 2% to cause the bracket arms 22 and 23 to bear against the inner faces of the skirts 16 and 17, respectively, and further cause the leg 12 to be bindingly retained against the bracket arm portion 24 and the inwardly offset edges of the shelf surface 15 and the ends of the beads 13 and 19.

While the invention is illustrated in association with a shelf having a generally rectangular configuration wherein the adjacent shelf edges are normal to each other, it is to be understood, of course, that the invention may be employed with other shelves or the like having angularly disposed edges and connected to legs at their corners.

We claim:

1. In an article of furniture, a leg mounting for a' shelf or the like, comprising (a) a shelf having at least one pair of edges disposed at an angle to each other and forming a shelf corner at their juncture,

(b) a pair of skirts extending along said pair of edges and normal to the plane of the shelf,

(0) an inwardly rolled bead along the edge of each skirt remote from the shelf,

((1) said skirts and shelf having offsets formed therein at said corner forming a mounting seat for said leg, (e) a bracket having a pair of angularly disposed arms abutting the inner faces of said skirts, (f) a pair of fingers on said arms interposed between the skirts and beads along said pair of shelf edges for retaining said bracket in said corner, and
