ABSTRACT OF THE DISCLOSURE
A merchandising system is disclosed which provides improved supporting brackets for mounting wire shelves on spaced apart structures secured to a supporting wall. The supporting brackets are provided with a pair of detachable clamps by which the brackets can be simply hingedly attached to the sides of a wire shelf formed with a back wall as well as the sides of a more conventional wire shelf formed without a back wall.

Description

~0~3~7 This in~ention relates to Merchandising systems and more particularly to improved shelving structure therefor.
In shelf structure of the type which i9 in widespread _ use in retail ~tores for displaying merchandise, it is desirable to install shelving which may be several feet long.
The wire shelves fabricated of wire may vary in their longitudinal wid~h in ~ixed increments and may be positioned at any desired level. Thus, to accomoda~e such wire shelves, the supporting structures on which the wire shelves are mounted compri~e horizontally extending vertically spaced hangbar member~ which are fastened directly to the supporting wall and vertically extending horizontally spaced apart upright members which are adjustably attached to the faces of the hang-bar members.
l Inasmuch as the wire shelves conventionally mounted ,~ on the upright members of such supporting structure do not ,,, ;
l, have a back wall ormed thereon, care is required that article3 j carried on these shelves do not fall into or get trapped in the gap let between the back edge o the wire shelf and the su~porting wall. ThuS there are times when it would be desira~le to have some o~ the wire ~helves provided on such wall supporting ~tructure to be of the type formed with back walls or retaining and ~upporting articles being displayed ~ ~
l on the shPlves. . ;
¦ A w~ire shel with a back wall which is admirably -suitable or this purpose i~ di~closed in Patent No. 3,730,108 iusued~ on May l, 1973 to ~lvin L. Stroh. In accordance with I this patent, a wire shelf having a main outer frame fonmed ¦ with a back wall i8 provided with a pair of spaced reinforaing `3l 30 wire members having L ~haped hook ends which extend outwardly from the sides o~ the outer main frame of the shel~. For supporting the wire shel on a free standing portable supporting , . , ~ 3297 structure, speci.al rectangularly shaped brackets are attached to the pair of spaced hook ends on the sides of the ,~
wire shelf by a pair ~f spaced integrally formed loop elements ~.
formed on the upper half portions or a similarly formed pair of spacea loop elements formed on the lower half portions of each of the brackets. By such a choice of attachment, the brackets provide ~or ~upporting wixe shelf while further serving either as an end retaining wall for the shelf or merely as an unobstructing end support or the shelf.
While such wire shelves formed with ~ack walls would be highly desirable for mounting on the wall supporting istructure pre~iously described. the rectangularly shaped brac~ets provided wi~h a choice of loop element attachments to the pair of hook end~ on the sides of such wixe shelve~ ~ -are not practical or the present merchandising i~ystem since ;~:
they provide too much of an obstruction on the ends of the 5.
shelf and, further, interfere with the storage capacity o the next lower shelf, Furthe~ore, the mere adopting of the rectan~ularly shaped brackets disclosed in the previously ~:
referred to patent to the mexchandising system of the present .
invention would be d:isadvantageous in~that~ uch:bracket~ oould '~
not be attached on the transverse ~ides of the more conventional wire shelves without a back wall and it is inconvenient and co~tly ~o provide a diferently constructed bracket for wire shelves with a back wall and wire shelvss without a back wall. ~: :
Thus it would be highly advantageous to provide generally triangular shaped brackets with detachable fastening mean~
which can be interchangeably utilized to attach the bracket~
to either type of 9uch wire ~helves for use on the same wall .:
30: .~upporting structure.
..
Accordingly, one of the objects of the present invention is to readily adapt a wire shelf simply constructed ~:

~L0~3Z97 -~ith a bac]c wall for attachment ~o a wall supporting structure.
Another obj~ct o~ the present invention is to provide ~;
simply structured detachable clamps ~or positively hingedly ' ..
attaching a supporting bracket to L shaped hook ends extending from the ~ides o~ a wire shel~ provided with a bac]c wall.
; Another object of the present in~ention is to provide a simple detacha~le ~lamping structure on brac~ets by which t~ :
the brackets can just as readily be attached to the transverse sides oi the outer main frame of a wire shel~ formed wlthout lQ a back wall as ~hey can be attached to the L shapea hook ends of rein~orcing wire members extending outwardly from the sides : .
of the main outer frame o~ a wire shelf formed with a back wall. .

As shown in Figure 4, the hangbar members 1~ are securely fastened to the suppor~ing wall 13 by screws 22 passing through openings 23 in the back 15 thereof. A clip 25 for holding an upright member 14 on a hangbax member 12 is formed by bending a rectangular length 5 : -of spring steel back on i~self. Xn use, the ~ree ends of the ~-front portion 26 and back portion 27 o~ the clip are pried apart and placed over the end of the -Eace 16 of hangbar member 12 such the side edges o~ the.front and back portions of the clip can be positioned to bear on the edges of the slot 17. The width of the bent end 29 of the clip 25 is narrowed down such that it i~ ~ree to slideably move along the slo~ 17 ~ :
for po~i~ioning on the hangbar member 12. A hole 31 is . ~ .
provided in the ~ront portion 26 and an aligned threaded r opening 32 i9 provided on the back portion 27 of the clip 25.

Next to be described i5 the bxac]cet 51 with the ~ -pair of clamps 53 provid0d thereon for attaching the bracket 51 to the pair of hook ends 47 extending from the peripheral transverse sides of the shelf 40. Referring to Figures 3 and 5, the bracket 51 which is made o~ sheet metal ma~ be considered generally triangular in shape in that its outer end is naxro~ and its inner end is wider so that three spaced lugs 55 can be formed thereon. Xnasmuch as it is desirable to have the depths of the brack~ts 51 when mounted on the wall supporting structure minimized so ~hat they will not inter~ere with the viewing of the articles being displayed on the shelf , 40 and the storage o~ articles on the next lower shelf, the rear bottom portions 57 of the brackets just in front o the lug or inner ends thereo~ can be cut away.
'I As best shown in Figure~ S and 6, each clamp 53 comprises a rectangular strip of metal having an upper curved portion 58 and a lower flat portion 59. ~he lower flat portion 59 is fastened onto the braclcet 51 by a ~ut and ~olt structure 61 which passes through openings on the bracket 51 and the flat poxtion 59. The opening provided on the outer end of the bracket 51 for the nut and bolt structure 61 is a slot G2 which provides for adjustment of the spacing o~ the clamps 3 ~
! 53 to fit the spacing of the pair o hook ends 47, if necessary. ~ -; The curvature o the curved portion 58 o clamp 53 is such that it ~ears closely against the rounded ~urface of ~ ~
..
the wire forming the hook end 47. Thus, when the nut and i bolt ~tructures 61 o~ the clamps 53 are tigh~ened, the trans-, ¦ verse hook ends ~7 extending from the sides of the shelf are held up closely against the face 52 o~ the bracket 51. It should now be cl~ar that ~he hook e~ds 47 having a circular cro~s sectio~ ~orm a hinge joint with the curved portions 58 ":, , . . , -. . .: . , . . .. : . . . . : , ~L~43Z97 o~ the clamps 53 about whlch the face 52 of the bracket 51 can be positively xotated.
As shown in Figure 4, the three lugs 55 on the inner end o~ the bracket 51 are vertically spaced ~rom each other such that th~ bracket 51 can be mounted on an upright member 14 at a desired position by in~erting the three lugs 55 through three adjacent openings 21 in the upright 14 and pushing down on the brac~et 51 such that the hoo]c porti.ons 56 on each of the lugs S5 en~age the rear o~ the front wall, i.e., the face o~ the upright memher 1~. It should be noted that inasmuch as the upper edga 63 of the bracket 51 is actually slightly above the upper edge of the main frame 41, the portion of the bracket 51 which extends below outer frame 41 o the shelf 40 or the purpose of providing suf~icient strength to support the shel~ is minimized. Furthermore, the depth of the bracket 51 below the bottom of the shel~ 40, which obstruct~ the sid~ viewinq o~ articles displayed on the I shelvea and the storage o articles on the next lower shel ~ ;
is minimized.
The fa-~tening o~ the pai.r of clamps 53 on the brackets 51 by the nu~ and bolt ~tructure 61 which can be readily detached, i.e~, loosened and tlghtened, to enable the curved portions 58 of the pair o~ clamps 53 to respectively fit ~ -closely on the pair o~ L shaped hook ends 47 o the wire YeS ~0, i9 ~ery desirable. The ~ shaped hook ends 47 on I the wire-shel~ 40 have projections 64 on the in~er sides . .
thereo (F.igure 5). Thus, once the pair o~ clamps 53 are tightened by the nut and bolt structure 61, the pair o~ hook ' ends 47 are r~jtai~ed on the bracket 51 by the projection~ 64, - 30 while permitting the bracket 51 to he rotated about the -~ -r~
roun~ed sur~ace a~ the hook ends 47 to either a vertical I position ~(Figure 3~ or an inward horizontal position (Figures : .......... ...................................................................... . ., -8~

109~32~7 7 and 81 1ush with the bottom of the shelf 40 thus ~orming a compact unit for storage or shipping. ' AG shown in Figure 3, the wire shelves ~0 with the brackets 51 assembled on the hook ends 47 thereof are secured to a paix of accurately spaced uprig~t members 14 by inserting the three lugs 55 on the inner ends of the respective brackets : :
51 in three adjacent spaced openings 21 provided on the upriyht members 14. It should be understood that although the standard ~.
wid~hs o~ the shelves 40 as provided by diferent manufacturers may vary slightly, all ~he shelves as provided by one manu~acturer will be of the same ~idth. Thus, once the upright members 1~ have been adjusted on the hangbar members 12 to a .
spacing for receiving a given standard width shelf 40 as provided by a given manufacturer, such shelves can be readily mounted on the supporti~g structure by inserting the three . lugs 55 on the inner end~ of the brackets 51 in three adjacent ~ openings 21 o~ the upright members 14.
.~ As clearl~ shown in Figures 3 and 4, an ad~antage '~ o~ the extended hook ends 47 on the sides of ~he wire shelf ~-40 is that they enable the back wall 42 o~ tho shelf 40, ~hich is simply formed by bending up the rear portions of ~:
the straight transverse sides 44 o~ the main frame 41, to ;:~
fit between the pair of upri~ht membexs 14. It should be noted from Figure 6 that when the clamp 53 is tightly attached to the bracket 51 by the nut and bolt structure 61, the curved port~on 58 of the clamp 53 holds the hook end 47 .. ~:
:o~ the shelf 40 against the face ~2 of the bracket 51 at a : level just below the upper edge 63 o~ the bracket 51~ Thus, 1 the clamps 53 must be~formed o strip~ o heavy gage metal .~¦ 30 since they actually support the shelf 40.

'i ... . . ..... . . . . . . ..

~043Z5~7 ~he sides o~ shel 40 permits the mounting of the shel~ 40 formed with a back wall 42, when needed, onto the wall supporting structure. It should be ~urther evident that once ~he brac~ets 51 are assembled on the pair of hook ends 47 o l-he wire shelf 40, they can then be swung back against the bottom o~ the shelf 40, as shown in ~igure 7, to form a flat compact unit. mus~ the shelves 40 can be nested upon one ,~ -another 3uch ~hat several with brackets already attached i~ thereto by clamp~ 53 can be placed in a relatively ~mall area.
~ext to be described in connection with Figures 9, 10 and 11 is the more conventional type o~ wire shel 49 which is mounted on the wall supporting structure shown in Figure 1 when there is no need to provide a shelf with a ~ack wall. The wire shel 49 compxises a generally rectangular outer main frarne 65 fabricated from relatively heavy gage wire.
The peripheral transverse wire sides 67 of the outer main frame 65 define the flat bottom of the wire shel~, while the .~
rear wLre poxtion of the main rame 65, which remains at the ~;
~ame level a9 the ~ransverse wire sides 67, deines the back ~ .

2~ 48 o~ the shel, and an upwardly front portion o~ the main ~xame de~ines the front wall 69 o~ the shel. A yrillwork of ~. :
lighter gage wire secured within the main frame 65 consists o~ a plurality of spaced wire elements 70 which ~end in a direction ~ubstantially parallel to the txansverse sides 67 of the main rame and a plurali~y o~ spaced wire elements 71 which e~tend normally to the transverse sides 67 o ~he main ~xame. A heavy gage wire reenforcing member 66 forming a part o the main frame 65 may extend adjacent khe centrally disposed wire element 71 as shown in Pigure 10. The various wire elements ~0, 71 o~ the grillwoxk may be secured together and ~ ;
to the main ~rame 65 by welding. ~ -The wire shel~ 49 uses the same supporting bracket 51 : ' ' ,.. ~'-, ~ 10 . .: .
: " ' . ' ~ 4;~297 previously descrlbed to support shelf 40 in that it is attached by the pair of clamps 53 to the transverse wire sides 67 of tha main frame which sides are parallel to the top edge 63 of the bracket 51. As before described, to assemble the brackets 51 on the sides of the shelf 49, the nut and bol~ structures 61 holdin~ the clamps 53.are loosened and the transverse wire sides 67 of the outer frame are placed into the curved portions 58 of the clamps 53. The tightening of the nut and bolt s~ructures 61 then causes the curved portions 5B of the clamps 53 to bear closely against the transverse sides 67 causing the latter to be draw~ up against the face 52 o~ the bracket 51 as the nut and bolt r structure is tightened. As shown in Figure 9, the slots 62 on the outer end portions of the brackets 51 permit the pair of clamps 53 to be spaced so as to bear up against the outer .
sides o~ the ront and rear wire elements 71, thereby preventing an~ inward-outward movement of the shel 49 relative to the ~;
, bracket. As illustxated in Figure 11, the bracket Sl is thus .
~, held such that it can be positively pivoted by its face 52 about the peripheral surface of the wire having a round cross . section and forming the transverse side 67 of the outer frame :-.
65 to assume elther a vextical position for mounting on the upright member~ 14 or to assume a hoxizontal position, as . .
j sho~m by dashed lines in ~igure lL, whereby the bracket 51 . ,~' is swung back flush against the bottom of the shelf thus forming a compact unit for storage or shipping.
¦ It should now be clearly understood that the ¦ manufacturer of the wire shelves 40 and 49 may mount the ~ brackets Sl on the end members of the shelves~ i.8., on the ":

3 30 hook ends 47 o shelf 40 or on the transverse sides 67 of the 1 .
outer main frame 65 of shelf 49. Then, by rotatin~ the i ~rackets Sl ~ack against the bottoms of the shelve~ 40 and 49 - -11- :
.1 . .. .

.`' ' ~' '' . ' ~)43Z97 several o~ ~he shelves.may be stacked together and shipped.
The shelve3 40 and 49 when received in a retail store are thus provided with the brackets 51 already attached to the sides ~hexeof. Thus, when either orm o~ the shelf 40 or ` 49 is talcen out of the shipping carton the supporting brackets 51 thereon.need be merely s~ung downwardly to a vertical position such that ~he lugs 55 on the inner end thereo can be fitted into the vertical openings 21 on the pair of upright member 14 pxeviously secured in posi~ion on the hangbar members 12 to accomodate such a shelf of the d~sired standard width. If the upright membexs 14 ~houla~ .
need adjus~ment to accomodate the standard width shelves,~-.
this neea only be.done once and the rest of the standard width shelves o~ the same form ~'till it thereon since they all come from th~ ~ame manuactur~r.
I In view of the above, it should now be clearly. :. :
understood that an important advantage of the shelf supporting bracket 51 provided with a paix o readily detachable clamps :-53, as shown and described herein, is that the same bracket . 20 51 is able to just as readily be attached on the hook ends 47 ext~nding ~rom the sides o~ the outer fxame o~ a wire . ~
shelP 40 formed with a rear wall ~2 as it can be attached to ..
the transverse sides 67 o~ the outer frame of a more conventional backless wire shelf 49. Thus, such a construction.o~ the. ~ . ;
bracket 51 eliminates the need ~or~providing dif~erent forms of construction~or.the two t~pes o~ shelves.
From the description it will be apparent that there ~ :
, is thus provided a device of the character described and ;¦ ~ possessi~g the particular ~eaturès of advantags before .: ..
