2 Claims. (Cl. 248174) This invention relates to paperboard display stands or similar structures of paperboard or like material. which can be collapsed into a relatively flat compact condition for shipment prior to use and for storage when not in use. In particular, the invention relates to paperboard structures of the general type mentioned where one part, usually the top, extends laterally beyond another part, usually the base, in order to provide an attractive and useful stepped construction giving the effect, for ex ample, of a relatively wide display case with a narrower supporting pedestal.

Paperboard structures of this general type have been provided in the past, one example being found in U. 8; Patent 2,066,844 to Lynch. However, such structures have been relatively unwieldly to set up, since-it has been necessary to expand the structure and then continue to manually restrain the natural collapsing tendency of the structure during the infolding or insertion of lock-' ing overflaps.

We have provided a structure of the type described which is locked in expanded position by the very act of expansion and which therefore exhibits no tendency to collapse during the infolding or insertion of such supplemental locking overflaps and such other elements as it may be desirable to provide.

Another advantage of our structure is that any tendency of the top and base, when collapsed, to move slightly toward and away from each other in telescoping relation is eliminated, thereby providing a firmer collapsed package which is less subject to the flexing and chafing and consequent loss of body and stiffness which similar structures of the prior art have experienced, particularly under impact loads incident to shipping and handling. Our structure is also stronger and more rigid whenerectedthan those of the prior art.

We achieve the above objects and advantages by providing connections between the top and bottom assemblies of the structure, which connections embody what might be termed a toggling feature which resists changes in the folded relation of the connecting'elements in both the expanded and collapsed conditions of the structure.

The above and other objects and advantages of the invention and its mode of operation will become clearer from the following description of an embodiment of the invention, which is given by way of illustration-and Figures 2-5 are side views of the structure shown-"in Figure l at succeeding stages of expansion.

Figure 6 is a sketch in perspective of the structure in the condition shown in Figure 5, certain elements being, omitted for clarity.

Figure 7 is a sketch in perspective showing a later stage in; the'complete assembly of the particular embodiment illustrated.

Figure 81is a sketch in perspective showing the'final and complete assembly of the particular embodiment illustrated.

Figures 9-12 are layouts of the several blanks which the illustrated embodiment may comprise.

Figures 13-46 are views on an enlarged scale and in cross-section, taken on lines 1313 in Figure 2, 14-14 in Figure 3, 1515 in Figure 4, and 16-16 in Figure 5, respectively.

Figure 17 is a view, on an enlarged scale, of the upperportion of Figure 2.

Figure 18 is a view, on an enlarged scale, of the lower portion of Figure 2.-

The particular embodiment illustrated, in its fullest elaboration, may includeone tubular element or pedestal generally indicated at 20, another tubular element or top. generally indicated at 21, a bottom pad generally indicated at 22 and a tray pad generally indicated at 23 (see Figures 9-12, respectively).

Thetube may comprise plain side walls or panels 25 and intermediately scored or foldable side walls or panels 26, the side walls or panels 25, 26 being separated byjfold lines 27. A tab 28 is appropriately glued or fastened to the opposite free end of the panel assembly to .form a tube. The cuts 29 and fold lines 30 define plain tabs 31 and intermediately scored or foldable tabs32. The tabs 3i and 32 have, respectively, intermediate tab portions or panels 34 and 35 defined between' the fold. lines 30 and fold lines 36 and outer tab panels 37' and 38. Suitable tabs 39 may be pro! vided at the opposite'end of the tubular assembly 20.

The tabs32 are intermediately cut and severed by the cuts 40 andaligned therewith are intermediate folds or scores 41 in the panels 26, which preferably have the form of non-severing cuts extending from the inside of the tube to the outer liner of the paperboard stock with out severing such outer liner.

The tube 2l'may comprise plain side walls or panels 45' and intermediately scored or foldable side walls or panels 46, the side walls or panels 45, 46 being separatedvby fold lines 47. A tab 43 is appropriately glued or fastened to the opposite free end of the panel assembly to 'form a tube. The notches or cuts 49 and fold lines 50, 51 define plain tabs 52 and intermediately scored or foldable'tabs 53. The tabs 52 and 53 have intermediate tab' portions or'panels 54 defined between the fold lines 51 and fold lines 55 and outer tab panels 56. v

The side walls or panels 46 are provided with intermediate folds or scores 57 which preferably have the form of non-severing cuts extending from the inside of the tube to the outer liner of the paperboard stock Without'severing such outer liner. The folds or scores 57 extend intermediately along the tabs 53.

The bottom or pad 22 may be provided with a central hole and with suitable tabs 58. The traypad 23 may also be provided with a central hole.

Inthe particular embodiment illustrated, the tabs 32 each comprise pairs of tabs due to the intermediate severance at 40. However, it will be understood that each line 40 may less preferably be merely a fold line or score line, in which case the tabs 32 are each divided'not' into separate tabs but into two co-joined portions.

The outer tab panels 37 and 38 are glued or fastened lie on or at the adjacent ends of the tubesZG and 21 with the intermediate tab panels 34 and 35 extending therebetween.
