Johnson, Minneapolis, Minn., assignor to Waldorf Paper Products Company, Ramsey, Mind, a
corporation of Minnesota Filed Aug. 19, 1963, Ser. No. 302,862 9 Claims. (Cl. 211-153) This invention relates to an improvement in shelf extends and deals particularly with a folded paper board tray which may be mounted on the forward edge of a store shelf to project outwardly therefrom.
In modern day supermarkets, goods of all types are usually stacked up neatly on the shelves from which they can be readily removed by the customers. Because of the fact that there is often one product after another in cans or bottles of similar shape and size, some difiiculty is experienced in finding a particular product. In cases where some item is on special sale, or a new product is being introduced, some means must be provided for separating this product from the others so that it will standout and be readily noticed. In some instances, special floor stands are provided for this purpose. In others, shelf extenders are provided which project beyond the shelves and forwardly thereof so that the product contained therein is more readily visible than the product on the shelves.
In order to accomplish their desired result, shelf extenders of this type must be relatively inexpensive, as they are thrown .away after a relatively short period of use. More permanent metal shelf extenders could be provided, but in such a case the extenders would have to be used for various products in order to be economi cally practical, and it is usually desired that the surfaces of the shelf extender be used for advertising purposes. As a result, shelf extenders formed of less expensive materials, such as corrugated paperboard have'been found somewhat more practical than the metal units. Shelf extenders of this type may be readily printed with the necessary advertising copy and may be produced at low enough cost so that they can be discarded after the period of advertising has been passed.
A feature of the present invention resides in the provision of a shelf extender which is formed of disposable material and which is sutficiently strong to support a considerable weight of product. As a result, the device may beused as an advertisement for canned goods or bottled goods which are normally quite heavy.
A further feature of the present invention resides in the provision of a shelf extender which may be either shipped in a flat state or which may be shipped in a rectangular container without a material loss of space. In order to simplify the operation of the supermarket operators and to assure the fact that the shelf extender will be used, rather than thrown away, portions of the brackets which connect the extender to the shelf are folded flat against a wall of the tray, the tray being filled with the product, and the unit is placed in a rectangular outer container for shipment.
These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.
In the drawing forming a part of the specification;
FIGURE 1 is a perspective view of the shelf extender in place upon a shelf. 1
FIGURE 2 is .a rear perspective view of the shelf extender in readiness for operation.
FIGURE 3 is a perspective view of the partially folded tray, illustrating the manner in which the tray is assembled.
FIGURE 4 is also a perspective view of a portion of the tray in a later step of the assembly.
FIGURE 5 is a rear perspective view of a portion of the shelf extender showing the supporting brackets in partially assembled form.
FIGURE 6 is a view similar to FIGURE 5 but showing a later step of the assembly operation.
FIGURE 7 is a diagrammatic view of the blank from which the extender is formed. The shelf extender is illustrated in general by the letter A and is designed to engage the forward edge of a shelf D to extend forwardly therefrom. The manner in which the shelf extender appears in use is illustrated in FIGURE 1 of the drawings, the contents of the tray being omitted in order to better disclose the construction.
As indicated in FIGURE 7 of the drawings, the shelf extender includes a tray portion having a rectangular bottom panel 10 foldably connected along parallel fold lines 11 and 12 to a front wall 13 and rear wall 14 respectively. In preferred form, the rear wall 14 is substantially higher than the front wall 13 to provide suflicient strength without concealing the goods.
Trapezoidal corner flaps 15 are hinged to the ends of the front panel 13 along parallel fold lines 16. The shorter parallel side of each corner flap 15 adjoins the fold line 16 and the wider parallel side 17 forms the free end of the flap. One edge 19 of each corner flap 15 is substantially an extension of the fold line 11 and is at right angles through the fold lines 16. The other edge 20 of each flap is angled to follow the shape of the tray end walls which will be described.
The tray ends include outer end wall panels 21 which are hinged to the ends of the tray bottom 11 along parallel fold lines which are generally aligned with the fold line 16 but which are slighty offset outwardly to permit each corner flap 15 to fold inwardly of the adjacent outer end wall 21. The end walls 21 are of trapezoidal form with the shorter parallel edge 23 substantially equal in height to the front wall 13 and the longer parallel wall 24 equal in height to the rear wall 14. The edges 23 and 24 are at right angles to the fold lines 22. The inclined upper edges of the end walls 21 are connected along double score lines 25 to end wall liner panels 26 which are substantially similar in shape and area to the outer end walls 21. As a result, when the liner panels 26 are folded along the double fold line 25, the liner panels may assume substantialy contiguous relation with the outer end walls.
' The edges 27 of the liner panels 26 which extend along j The longer parallel side of each of the trapezoidal end liner panels 26 is connected along a fold line 28 to a generally triangular flap 31, one edge 32 of which will extend along the upper edge of the rear wall 14 in folded form of the extender, as is best illustrated in FIGURE 4 I of the drawings.
The longer side 24 of each of the outer end wall panels 21 is connected along a fold line 33 to a bracket flap 34, each bracket flap 34 projecting from the upper portion of the edge 24 in the folded form of the extender. The lower portions of the edges 24 are connected along fold lines 35, which are aligned with the fold lines 33, to a lower bracket arm 36. The bracket flaps 34 and the bracket arms 36 are in spaced relation and the extremities of the arms 36 which are most remote from the end walls 21 include widened portions 37. The upper edges 39 of these widened portions 37 are slightly below the level of the lower edges 40 of the bracket flaps 34 to permit the shelf B to be inserted between the bracket flaps and the bracket arms.
The rear extremities of the bracket arms 36 are connected along transverse fold lines 41 to reinforcing bracket arms 42. I V bracket arms 42 follow the shape and contour of the bracket armsv36 when folded in face contact therewith.
The upper surfaces of the reinforcing bracketarmsto be folded in the manner shown in FIG- The reinforcing bracket arms 42 include anchoring.ex-'
tremities 43 which are substantially the full height of the 7 rear portions of the end walls 21 and are sandwiched be tween the end walls 21 and end wall liner-panels 26 when the structure'is folded. The anchoring, portions 43include auxiliary bracket flaps 44 which are designed to'lie.
in face contact with bracket flaps 34 and to act as a reinforcernent'therefor. Thus both the bracket armsand bracket flaps are of double thickness. I
The rear wall panel 14 is connected along a double s core line 46 to a rear wall liner panel 47. Thisliner panel 47 is provided with short projecting locking tongues:
49 thereupon and the bottom panel 10 is provided; with elongated slots 50 into which the locking tongues 49 may URES and 6 of the drawings.
In usual practice, the tray portion of the shelf extender is usually set up in the manner'described-and the bracket 'the bracke t arms are hinged to the rear edges of the end engage when the liner panel 47 is folded into contiguous parallel relation to theirear wall 14. I
Inthe assembly of the shelf extender A, the front wall panel 13 is folded up into right angular relation to the bottom panel along the fold line 11, and the corner flaps 15 are folded at right angles to the. front panel tov extend along the fold line 22. FIGURE 3 of the drawings show the parts in this relation. Thetrapezoidal end wall wall panel's, they are reinforced by'the anchoring ends of the reinforcing bracket arms which are not similarly folded. It should also be noted, thatthe fold lines 52- do not materially weakenthe jarm structure, as the corresponding area of the bracketarms are" not folded at this point.
In accordance the patent statutes, I have described the principles of construction and operation of my shelf extender, and whilel'have endeavored to set forth the best embodiment thereof, I desireto have it understood panels 21 are ,nextfolded upwardlynoutwardly of the corner flaps 15, and the end wall liner panels 26 arethen folded along the double fold lines 25 until the locking tongues 2Q engage in the slots 30. The liner panels 26 thus hold the front wall'in right angular relationto the end walls 21 and to the bottom panel 10. Due-to the" trapezoidal shape of the end walls and liner panels there is a tendency for the forward corners of the liner panels 26 to engage the front wa1l13 and bend as they are folded into parallel relation to the end wall panels 21. Diagonal,
fold lines 54 may extend across the lower front corners of the end wall liner panels 26 to permit such temporary.
flexing without injuring the paperboard.
The corner .flaps 31 are next folded inwardly into a common plane, and the" rear wall panel14 is folded up against the corner flaps 31, the edge 32 extending along the double fold line 46 connecting the rear wall 14 to that obviouschanges may; be made within thescope .of the'following claims without'de parting from the spirit of my invention. a
Iclairnfj 1. A shelf. extender including a generally rectangular tray of paperboard, the tray including a'bottom panel,
front, rear .and end walls extending upwardly therefrom,

2. The structure of claim land in which said bracket "arms comprise a pair ofjarm members foldably conthe rear wall liner panel 47. *This brings the; structure I 7 into the position'illustratedfin FIGURE 4. The liner panel 47 is then swung inwardly and downwardly until the locking tongues 49 engage inthe'slots 50. The corner flaps 31 are enclosed betweenfthe'panels l4 and 47'to hold the rear of the tray. assembled. a This completes the 5 formation of thetray.
With the tray portion of the structure assembled, it
, would not be possible to assemble'the bracket arms in place without bending one or the other of the arms except for the provision of a pair of'score lines'52 parallel v to thefold lines 41 which connect the reinforcing bracket arms 42 to the bracket-arms 36. In folding the arms the reinforcing bracket arms 42 are folded along the fold line 52 as indicated in FIGURE 5 of the drawings. From ne'cted and extending in face'contact. a 7

anchoring portion 43 enteringthe space between theouter end wall panel 21 andthe adjoining end wall liner panel] 26. During this operation, the bracket arms are flexed ,to some extent but not to the extent necessary to injure the structureof-the'paperboard. As the areas .53 swing toward coplanar relation with the remainder 'of the re-' inforcing bracket 42, the flexing of the arms decreases until finally the reinforcing bracket arms 42 are again in face contact with the bracket flaps 34. When injplace,
the bracket structure. appears as best illustrated in FIG- URE 2 of the drawings.
,In order to function m the manner described,- it is' necessary that the areas 53 between-the fold lines 41'and 52 be of the width no greater than /z the extent-to which 4 the anchoring portions 43 arelinserted. er it h wiched b tween said from; said rear panel adapted "to underlie a shelf, and reinforcing bracket arms hinged to the rear extremities of saidbracket armsand folded in face contacttherewith, the ends of a said reinforcing'bracket' arms extending between said end wallpanels and said end wall liner panels. 7 .4.
