STAINLESS STEEL SHEET METAL STORAGE SHELVING Oct. 3; 1967 Filed June 17, 1965 INVENT OR ATTUHV 5.
United States Patent C) 3,344,756 STAINLESS STEEL SIEET METAL STDRAGE SI-ELVING Lester Kelson, Cluster, N J assignor to S. Blickman, Inc, Weehawken, N.J., a corporation of New York Filed June 17, 1965, Ser. No. 464,616 1 Claim. (Cl. 108106) This invention relates to shelving and more particularly to stainless steel sheet metal storage shelving.
A primary object of the present invention is to provide improved corner leg brackets by means of which such shelfing may be supported in parallel relation on legs and for adjustment of the spacing of the shelving.
Another object of the invention is to provide a corner leg bracket which can be made up independently of the shelf panel itself so that lengths may be made up quickly and easily to order without requiring stocking of a larger number of sizes, to provide a leg bracket which blends with the shelf panel so as to be attractive, and to provide a leg bracket which is designed for casting in quantity with an appreciate saving in cost of manufacture.
Still another object is to provide shelving of improved rigidity and stiffness that is sanitary and easy to install.
For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:
FIGURE 1 is a perspective view of shelving embodying my invention.
FIG. 2 is an enlarged sectional View taken on the line 22 of FIG. 1, parts being shown broken away.
FIG. 3 is an enlarged sectional view taken on the line 3-3 of FIG. 1.
FIG. 4 is a disassembled perspective view of the bracket and adjacent corner of the shelving.
Referring now more in detail to the drawing, the shelves embodying the present invention and shown are made up of stainless steel sheet metal, preferably of cast aluminum, or any suitable length and width. Each shelf has a central flat panel of substantially rectangular shape and right angular disposed downwardly extending end and side flanges 12 and 14, respectively, situated with their upper and lower edges above and below the panel. Round, inwardly and downwardly extending shoulders 16 connect the upper edges of the side and end flanges with the panel. The lower edges of the end flange and the side flanges are provided with right-angularly disposed inwardly projecting flanges 18 and respectively turned upon themselves forming hems 20 and 22, respectively. The shoulders serve to prevent spilled liquid from flowing over the edges of the shelves onto subjacent shelves. The side flanges constitute a peripheral skirt.
At each corner, the inwardly extending flanges 20 and hem 22 are cut away as indicated at 24, and at each corner the panel 10 is formed with a round opening 26. A scew 25 with one end welded to the under surface of the body of the panel 10 as indicated at 27 depends from said under surface inwardly of but adjacent to the opening 26. In each of the cutaway portions 24, there is a leg or shelf bracket 28 shown in detail in FIG. 4. Each bracket has a triangular shaped aluminum solid body 30 \m'th a project ing shoulder or bead 32 along the top edge thereof. The depth of the body and shoulder corresponds with the depth of the flanges 12 and 14 so that the body and shoulder are adapted to lie inside the flanges 12 and 14 with the upper shoulder 32 thereof situated within the upward- 3,344,755 Patented Oct. 3, 1967 1y concave sides of the shoulder 16 along the top edges of the panel. A central opening 34 is formed in the body 30 of the bracket and has a raised annular head 36 therearound. The upper edge of the bead 36 lies in a plane above the top surface of the body 30 by an amount which corresponds to the thickness of the panel 10 so that the upper surface of the beads 36 will lie flush with the upper surface of the panel 10. Another hole 38 smaller in diameter of opening 34 is formed in the body 30 adjacent the apical point of the body, for receiving the screw 25 depending from the panel 10. A lock nut 39 threaded on the end of the screw against a washer 41 secured the bracket 28 to the panel 11). At one side of the bracket body 30, there is a horizontally disposed threaded opening 40 for receiving a set screw 42 by means of which the bracket 28 is fixed to a tubular supporting leg 44 such as shown in FIG. 1.
A shelf formed as above described is readily and economically assembled from stock material with a minimum of labor. Machine operation can be used for the formation of the panels and depending flanges. The set screws 42 maintain the predetermined spacing between the panels or shelves 10.
While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.
What is claimed is:
Shelving comprising a plurality of spaced shelves supported on upright legs, each shelf comprising a rectangular panel having openings spaced from the corners thereof, through which said legs extend, flanges depending from the peripheral edges of the panels and extending about the entire periphery of each shelf, inwardly extending flanges along the bottom peripheral edges of the depending flanges, turned-over hems on the inner peripheral edges of said inwardly extending flanges, said inwardly extending flanges having cutouts at the corners of the panel, leg supporting solid brackets in said cutouts, said brackets containing leg receiving openings perpendicularly to the plane of the panel, in line with the corner openings of the panel, beads around the openings in the brackets extending above the top surface of the bracket through the corner openings in the panel, set screw means for removably securing the brackets to the legs, screws depending from the panels adjacent the corner openings thereof, said brackets having holes therethrough adjacent and parallel to the openings through which the screws depend from the panels, and lock nuts on the protruding ends of the depending screws.
