INVENTOR. ROBERT G. CHESLEY WILSON, SETTLE 8x CRAIG ATTORNEYS United States This invention relates to a shelf structure, and more particularly to a shelf structure for displaying -retail merchandise which may be readily installed on a supporting wall surface with various arrangements of the component parts to -accommodate different loading conditions and which when installed forms a rigid secure structure.
It is au object of the invention to provide a shelf structure for the display of retail merchandise.
Another object of the invention is to provide ya shelf structure having a knock-down construction which may be Ireadily mounted or removed from a supporting wall.
A further object of the invention is to provide a shelf structure in which the shelf may be positioned at different vertical levels as desired.
Another object of the invention is to provide -a shelfsupporting bracket which permits forward and backward adjustment of the shelf with respect to the supporting wall.
A still further object of the invention is to provide detachable fastening means for securement of the `shelf to the shelf-supporting bracket.
Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.
In the drawings:
FIGURE l is a view in perspective of one embodiment of the shelf structure of the present invention;
FIGURE 2 is a side elevational view of the rear portion of the shelf-supporting bracket illustrating the means for attaching the bracket to the supporting walls and the means for attaching the shelf to the bracket; and
FIGURE 3 is a -sectional view of the bracket shown in FIGURE 2 taken substantially along the line 3 3 of FIGURE 2 looking in the direction of the arrows.
Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
Referring to the drawings it will be seen that the shelf structure comprises uprights 12 secured to a supporting Wall 14. Each upright carries a horizontally extending shelf-supporting bracket 16. A wire shelf 18 is supported in a substantially horizontal plane on the bracket 16.
As will be noted in FIGURES 1 and 2, the uprights 12 are channel sections having legs 2t), 22 joined together by a web 24. The uprights are positioned with the legs 20, 22 abutting against the wall 14. Recessed openings 26 are provided to receive screws 28 which threadingly engage the wall to secure the uprights in place. As shown, two uprights are provided. However, more may be utilized if desired.
A plurality of vertically spaced generally rectangular openings 30 are provided in the web 24. The openings 30 permit mounting of the bracket 16 at different vertical positions whereby the shelf 12 may be located at any desired vertical level.
The brackets 16 are of generally triangular shape fand are positioned with the upper shelf supporting edges 32 arent ice in the same horizontal plane. As illustrated in FIGURE 2, the inner end of each bracket is provided 'with a pair of lugs 34, 36. Each lug has an inwardly projecting portion 38 'and a downwardly projecting portion 40` to form an L-shape. The edge 42 of portion 40 is spaced from the edge 44 of the bracket a .distance appror'xirnately equal `to the thickness of the web 24. The lugs. 34, 36 are vertically spaced from each other a distance approximately equal lto the distance between two of the openings 30 in the uprights. The bracket 16 is formed with relief slots 46 adjacent the lugs t-o permit easy insertion of the lugs into the upright openings.
In operation, the brackets are mounted on the uprights by inserting the lugs 34, 36 through a pair of openings 36. Upon insertion of the lugs through the openings, the bracket is forced downwardly whereby the lug edges 42 will engage the inner 'surface of `the Web 4and the bracket edge 44 will engage the outer surface of the web to lock the bracket securely in place. The bracket is also provided with a pair of tabs 48, 50 at its inner end which are bent outwardly in opposite directions for abutment against the upright web 24 to provide lateral support for the bracket.
As previously mentioned, the wire shelf 18 is supported on the upper edges 32 of the bracket. The shelf 1S cornprises a generally rectangular outer frame 52 fabricated from relatively heavy gage wire. A grill-Work of lighter gage Wire is secured Within the frame 52. The grill-Work. consists of a plurality of elements. S4 which extend transversely of the bracket 16 and 'a plurality of elements 56 which extend in directions substantially parallel rto the edge 32 of the bracket. The various wire lelements of the shelf are secured together by welding lass shown at 58 in FIGURE 2.
The forward marginal portion 60 of the shelf is bent upwardly to form a retainer for larticles positioned on the shelf. A wire element 62 of relatively heavy gage is provided on the retainer 66 to -act as a reinforcement.
The shelf 18 is secured to the lbracket 16 by means of str-aps 64. The shelf is positioned on the bracket with e. wire el-ement 56 overlying the bracket edge 32. The strap 64 is then looped around the wire Iand secured to the bracket by la bolt structure 66 as shown -in FIGURE 3. This detachable fastening prevents the shelf from shifting after it has been positioned on the bracket.
As will vbe noted in FIGURE 2, an elongated notch 68 is provided in the upper edge of the bracket adjacent the inner end thereof. The notch 65 receives the large diameter frame wire 52 to compensate for the smaller diameter wire elements 54 and avoid canning of the shelf. The shelf may be adjusted forwardly or rearwardly a distance equal to the length of the notch 68. This adjustment Ifeature permits varying the effective dept-h of the shelf to accommodate articles of different sizes.
Having thus described my invention, I claim:
