(Cl. 2li-138) 9 Claims.

This inventionl relates to display racks, and particularly to a, display rack which is constructed of metal tubing and welded Wire rod to provide a strong, lightweight structure and, as will be pointed out hereinafter, a tensioning action which contributes to the carrying out of the invention.

The class of merchandise with which the display rack is intended primarily to be used is that including packaged bakery products such as biscuits, crackers, cookies, cakes, pretzels and the like. However, it will be obvious that the rack is not limited to use with these specific goods, but may be utilized Wherever a maximum amount of merchandise is required to be effectively displayed in a minimum amount of space, for example, in stores of the self-service type.

'Ihe prevailing tendency is to package merchandise in transparent cellophane or waxed paper bags, or in trays wrapped in those materials, in order that the contents may be seen by the purchaser. This is particularly true of items which have eye or taste appeal and are purchased on impulse. Various types of display stands for dispensing this class of merchandise have been devised heretofore, but they have not been satisfactory for many reasons, chiefl among which are visibility from one side only, complexity of fabrication and the tendency to gather dust and other foreign matter, necessitating continual and often dicult cleaning. The present invention contemplates obviating these and other objectionable features of the prior art.

One of the main features of the present invention is the provision of a shelf-angle adjusting structure whereby any one or all of the shelves of the display rack may be adjusted at will from a horizontal position to an inclined position of substantially open V-shape. Thus each shelf offers a choice of positions, either angular or horizontal, for displaying packages, bags, cartons, etc. in the most advantageous, effective and appealing manner. In addition, the open-Work structure of the display rack lends itself to ,the provision of maximum visibility of the mechandise from every angle of view. Each shelf is provided with an automatic locking structure which maintains it in either of its selected positions. Thus, the main or end supports of the rack are formed oi metal tubing bent into an inverted V-shape, .and the shelves are formed so that when adjusted to horizontal position the legs of each supportare sprung apart and placed under tension. Means associated with each shelf acts, .under the influence of the tension referred to, to. lock the shelf in horizontal position,

Another feature of the invention is the absence of nonessential parts, which enhances its aesthetic simplicity and eiciency. The display rack is constructed of parts arranged to provide a relatively lightweight structure in view of the overall dimensions of the assembled rack, yet when erected, the rack presents a strong, rigid unit. Being made entirely of metal, the display rack can be finished easily in any color or combina tion of colors which will harmonize with store fixtures or decorations; and if minimizing cost of manufacture is a prine factor, the entire structure may be sprayed with aluminum paint or chrome plated.

Theinvention provides a rack which is exceptionally well suited for setting up a so called island display. This adapts it especially for use in stores of the self service type, wherein customers are attracted to merchandise by its appeal and effective presentation. For certain types of store arrangements, the display rack is particularly adaptable in that when the shelves are in inclined position they can be loaded from the rear, and the packages will lmove by gravity to the base of the incline as other packages nearer the front of the shelves are removed. Furthermore, should it be desirable to stack merchandise on a horizontal shelf surface, say in arranging pyramid displays, any or all of the shelves may easily and readily be adjusted to horizontal position. Whether in horizontal or inclined position, in the event that several different items are placed in different areas of the shelves, nevertheless substantially all of them will be visible to the customer from any given position relative to the rack.

Still another feature of the invention, and one of great advantage, is the compactness of the rack in storage and when packed for shipment. The rack is constructed so as to be knocked down and assembled With ease and is held together by nuts tightened on the threaded ends of certain crossbars. Alternatively, either an inexpensive stamped metal wrench may be furnished with each rack ifordinary square or hex nuts are used, or to obviate the necessity of furnishing a wrench, acorn head hex nuts, which are easily held and tightened by hand, may be used. In its knock-down or collapsed form, the stand occupies very little space and all of the component parts can be packed in a small carton by arranging the flat surfaced parts and uprights in layers.

In the accompanying drawings, the invention has been shown merely by way of example and in preferred form and obviously many modifications and variations may be made therein and in its mode of application which will still be comprised within its spirit. It is to be understood, therefore, that the invention is not limited to any specific form or embodiment except insofar as such limitations are specified in the appended claims.

Referring to the drawings:

Fig. 5 is a view similar to Fig. 4, showing the shelf in horizontal position;

Fig. 6 is a detail vertical section, the view'being taken substantially on a line 6--5 of Fig. 2, looking in a direction indicated by the arrows; and

Fig. 'Z is an enlarged perspective view of an auxiliary shelf-locking support.

The display rack shown in Figs. l to '7, inclusive, is made entirely of metal tubing and welded wire rod. Referring particularly to Fig. l, the rack comprises spaced-apart uprights or end supports i and 2, a series of shelves 3, 4 and 5 supported one above the other between the uprights, and shelves 6 and I located outside the uprights one at each end of the rack at the level of the bottom shelf 3.` The uprights I and 2 are made preferably of tubular metal, such as iron pipe, bent to form substantially inverted V-shaped members which provide integralilegs 8, 9 and l0', i I. The shelves 3, t and 5 are fabricated of wire rod and are pivotally 'supported on horizontal crossbars I2 and I3, Ill and I5, I6 and I1, which extend between the uprights I and 2 and hold them in spaced apart relation. As shown in Fig. 2, at each shelf level the legs `8, 9 and I0, II are drilled to receive threadedends IB of the crossbars, the ends of each crossbar extending through both walls of the respective leg and being secured thereto by a pair of nuts I9 and 20 threaded on the end of the crossbar so as to clamp the respective leg between them. Thus, the uprights are held together in spaced-apart relation by'bars which are constructed preferably of a substantially heavy gauge iron rod.

Referring to Fig. 1, it can be seen that the display stand is built with a plurality of superposed wire rod shelves of identical construction. Their structure can be seen in Fig. 2, wherein the lower shelf 3 is shown as comprising front and rear hingedly connected shelf sections 2| and 22, respectively. Both front and rear shelf sections are substantially similar in construction and in the descriptionto follow corresponding parts of each member are designated bycorresponding reference numbers. a front bar or rod2`3 and a rear rod 24, to which a plurality of shelf wires 25 are connected preferably by lap welding, to form the actual package supporting surfaces. Preferably three rods 26 are located one at each end and a thirdsubstantially at the center of each member, the rods 213 being constructed of substantially heavier gauge wire than the cross wires 25 which Aform the shelf surfaces. The rods 2K6 areV lap welded to the undersurface of the frontandlrear rods 23 and 24, thereby forming a frame'to' stiff'enand strengthen Each shelf section comprises the structure of the shelf sections. The shelf stiffening rods of the rear shelf section 22 extend beyond the rear rod 2e and are bent to form a loop 2l (Figs. 2, 4;) which pivotally encircles the adjacent rear rod 2d of the front shelf section 2 I, thus forming a hinged connection between each pair of shelf sections 2| and 22. 'This construction furnishes a pivotal connection which is very readily and quickly formed and assembled, thereby uniting the two shelf sections to provide a foldable and unitary shelf structure.

Each of the heavy gauge rods 26 has welded to it a U-shaped eyelet 23 near its outer end as shown in Figs. 2 and 3, and in greater detail in Figs. 4, 5 and 6. vEach of the eyelets 2B is formed from a suitable length of heavy gauge iron rod, bent to form a snug fit around the crossbars I2-i3, Ill- I5 and lli-Il and are taclr welded at one side of their terminal ends to an appropriate side of the rods 25. Looking from right to left in Fig. 2, it will be seen that the eyelets 28 are welded to the right-hand sides of the rods 26 of the front shelf section, whereas the rear shelf section is constructed with its respective eyelets 23 welded to the left-hand side of the rods 26. This method cf attachment is to compensate for the space occupied by the loops 2 which preclude the rods 26 from occupying the same front-to-rear vertical plane and necessitates their side by side arrangement on the rear rods 213. Also, in addition to their use as pivotal supports for t e shelf Sections 2l and 22, they serve as spacers on the crossbars I2 and I3. The same is true in connection with the shelves 4 and 5.

As already stated, the present embodiment of the invention includes auxiliary left and right end shelves 5 and i (Figs. 1, 2 and 6) although it is fully contemplated that end shelves of a substantially similar character may be included at the higher shelf levels. A preferred construction of the end shelves (which are identical) is illustrated in detail in Fig. 2 and Fig. 6. Referring particularly to Fig. 2, the shelf l' comprises three sections 30, 3l and 32 of which the element 30, substantially triangular in outline, is hingedly joined to the trapeZoidal-shaped members 3| and 32 to form a substantially basket-like end shelf of rectangular outline. The basket or deep-tray effect is best illustrated in Figs. 1 and 6. The members 3l and 32 are disclosed as converging in a general direction toward a center line extending lengthwise through the display stand. Actually it provides a continuation of the V- shaped trough formed by the shelf 3 (Fig. 4) when in its depressed V-shaped position. The apex of the triangular member 3b is pointed downwardly toward the V-shaped trough formed by the members 3l and 32, and the surface of the member Sil slopes upwardly and outwardly therefrom.

The member 3d' comprises a substantially triangular frame 33 formed by bending a suitably rigid gauge of wire rod stock to shape. The extremities of the wire rod are lap welded to form a closed frame for supporting a plurality of shelf wires 34, which are spaced parallel to one another, extending from the base of the frame to the opposite sides of the triangle, and are welded to the upper surface of the frame 33.

The vtrapezoidal-shaped members 3l and 32 consist of frames constructed of wire rod similar to that used in forming the triangular shaped member 30 and are similarly formed by being bent to shape. However, by loops 35 and 36, formed similarly to the loops 21 and. the rods 26,

the members 3| and 32, one arranged at each side of the member 36, are each hingedly connected to the member 30 at its apex and at the respective base angle. The loops 35 and 36 form a hinged connection which enables the three members 36, 3| and 32 to be collapsed from their erected basket-shaped structure into a substantially flat unit which is comparatively less bulky and more economical to carton and store than when in its erected condition.

Means for securing the end shelves 6 and 'I to their respective uprights I and 2 is provided in each instance by welding a washer 38 (Figs. 2, 6) of suitable dimensions to the frame of each trapezoidal member 3I and 32 in position so that the center holes thereof are disposed to receive the threaded ends of the crossbars I2 and I3 and be clamped against the outer surface of the respective upright by the nuts 20. Additional means for supporting the shelves 6 and 'I is provided by braces 39, one of which is anchored to each upright leg 8, 9, I5 and II and has its opposite end fastened to the frame of its respective shelf by being looped, as at 43, therearound at the base angle of the triangular member 39, thus forming a pivotal connection suiciently flexible to permit the braces 35 to be folded flat when the display stand is disassembled, yet of sufficient rigidity when in erect position to lend support to the end shelves. Drilled holes 4I (Fig. 3) are formed in the leg members 8, 9, IIJ and II of the uprights through which threaded ends of the braces 39 are inserted and fastened by the nuts 42.

Further rigidity in the display stand is obtained by the provision of iron rod braces 43 (Figs. l, 6), one pair of which is employed to brace the front crossbar I2, and another pair similarly employed for bracing the rear crossbar I3. The braces 43 are welded at their upper terminal ends to the undersurface of the crossbars I2 and I3 and are formed to extend downwardly therefrom to the upright legs of the uprights I and 2. As in the case of the braces 33, the uprights I and 2 are drilled, as at 55, to receive the free, threaded ends of the braces 43, which are fastened thereto by nuts 44.

In order to insure effective rigidity of the shelves 3, 4 and 5 when in their horizontal position, especially when they are to support extraordinarily heavy display of merchandise, there is provided an auxiliary brace or locking member 45 (Fig. 7) for each shelf. Inasmuch as the widths of the various shelves may vary substantially, the braces 45 diier in length accordingly although they'are formed alike. As will be seen in Fig. 7, the braces are formed from a length of heavy gauge iron rod bent at right angles at both ends to form a pair of parallel arms 46 adapted to provide a transverse support beneath a group of the shelf wires 25 (see Fig. 2). A

shorter length of rod stock, preferably of equivalent gauge, is bent to form a substantially U- shaped member 4l, one leg of which is lap welded tothe center of the brace 45 in a position such that the legs of the member 41 extend parallel with main portion of the brace 45 and the unattached leg of the member 4l is above and spaced from said main portion. The brace 45 is applied beneath a shelf by sliding the U-shaped member 4'I over the center rods 24, whereupon the main portion of the brace extends beneath'the shelves on opposite sides of the rodsv24 and the Larms 46 thereof underlie a group of the ,shelf wires 25 near the outer edges of the shelves.v It is obvious that whenever it is desired to tilt the shelves to their inclined positions, the braces 44 are readily removed and laid aside.

As already stated the display stand is of the knock-down type which can be assembled easily. In erecting it, either upright I or 2 is held in standing position and one end of the crossbars I2 and I3 of the lower shelf 3 are inserted in drill holes 48 (Fig. 6). The nuts 20 may be loosely screwed on the ends of the crossbars I2 and I3 to hold them in place, although in practice this may be unnecessary since the frictional engagement of the threaded ends of the crossbars in the holes 43 will probably suice. The opposite ends of the crossbar are then loosely attached to the other upright in like manner. The remaining shelves 4 and 5 are then attached to the uprights in the same way as the shelf 3 and at this point may be left loose or fastened securely, as desired, but the bottom shelf cannot be tightly fastened until the braces 39 and 43 and the end shelves 6 and 'I are in place. Thus while the uprights can still be moved or sprung apart both front and rear pairs of braces 43 are inserted in their respective drill holes 50 in the uprights. Then end shelves 6 and 1 are placed in position on the threaded ends of the crossbars I 2 and I3 (Fig. 6) projecting through the drill holes of the uprights and the free ends ofthe braces 39 are inserted through the drill holes 5l] in the uprights. The nuts 20 on the crossbars i2 and I3, and the nuts 42 and 44 on the braces 33 and 43, respectively, may now be set up' to secure the shelves 3, 6 and I in place.

Any or all of the shelves 3, 4 and 5 may now be adjusted to either their horizontal position, as illustrated by the lower shelf 3 in Fig. 3, or to their inclined positions illustrated by shelves 4 and 5 in Fig. 3. Merchandise placed on the horizontal shelf 3 is indicated by dotted outline and designated 5I, and with the shelf in this position the brace 45 is inserted in place as shown in Fig. 4. The intermediate and top shelves, if depressed to their inclined position, will assume the position taken by shelves 4 and 5 in Fig. 3 and merchandise carried on these shelves may be placed as indicated by the dotted outline and identified by numbers 52 and 53.

In order to maintain the various shelves of the display stand in either their horizontal or their depressed V-shaped position, advantageis taken of the resiliency inherent in theuprights I and 2. The width of the shelves is such that in erected condition the legs of the uprights I and 2 are normally in outwardly sprung condition when the shelves are in horizontal position. Thus when the shelf is in horizontal position the inward pressure of the leg members will be applied through the shelf sections against the center rods 24, tending to force the shelf sections against each other laterally.v The looseness of the rods within the loops 2'I causes one to ride up on the other to a slight extent above center (see Figs. 3 and 5) and make an eifective friction lock which can be released only when sufcient downward pressure is exercised on the shelf to spring the legs farther apart. When a shelf is in its V-shaped position, the uprights I and 2 will move inward, and tend to maintain the hinged shelf sections in their V-shape position.

It is pointed out that due to the resiliency of the uprights I and 2, all o-f the wire rod shelving is continuously under tensionv and, consequently, looseness at the various pivotal connections is reduced to a minimum.

It may be appropriate to further describe how the shelves are prevented from rising at any time above their horizontal position to an inverted V-shaped condition. Referring to Fig. 4, it will be observed that the right hand shelf section is mounted off-center above the crossbar l2 a distance equivalent to the radius of the crossbar l2 by means of the U-shaped eyelet 28. In like manner, the left hand shelf section is mounted offcenter an equivalent distance above the crossbar I3 by means of a similar eyelet 28. In their horizontal positions, best illustrated by the lower-most shelf of Fig. 3", the sections are forced inwardly against each other, and looseness at the hinged joints is taken up to maintain rigidity. When the shelves are forced downward to their V- shaped position, the rotation of the sections about their pivots on the crossbars l2 and i3 will cause opposed arcs to be described by the inner extremities of the shelf sections, which arcs will gradually recede from one another as the angular rotation of the associated shelf sections is increased. Consequently, any downward movement of the shelves will be limited by the looseness in the hinged connection between the shelf sections, which looseness will be taken up by the horizontal distance which separates the arcs of the respective shelf sections. inasmuch, however, as the shelf sections are mounted off-center and above their pivots (the crossbars l2 and I3) the arc separation of the opposed shelf sections generated from the horizontal position downward to the depressed position, is substantially narrower than it would be if the shelf sections were mounted on center. Conversely, since the upwardly directed arcs formed by the shelf sections would recede from each other at a substantially faster rate than the downwardly drawn arcs, it is obvious that the separation distance between the hinged ends of the shelf sections will, should any attempt be made to invert the shelves upwardly, become suddenly too wide to permit such movement, because the hinge construction 24-21 is not provided with sufficient looseness to separate the required distance. This arrangement insures a positive locking arrangement at all times against any upwardly directed movement of the shelves above the horizontal position.
