arroeuEVS United States Patent 3,176 419 DISPLAY ASSEMBLY HA VING A CGLLAPSIBLE STRUCTURAL MEMBER Elmer L. Stein, Milwaukee, Wis, assignor to Eye-Beam Displays, Inc., 'Miiwaukee, Wis., a corporation of Wisconsin Filed Oct. 3, 1962, Ser. No. 228,068 Claims. (Q1. 40125) This invention relates to a display assembly having a collapsible structural member.
The present application is a continuation in part of application 845,114, filed October 8, 1959.
It is an object of the invention to provide a structural member which can be fabricated separately or as a part of a display and which, in either event, can be folded flat for shipment and which will either be self-erecting in the sense that it will spring to its position of use or, in any event, will be stable in its position of use, notwithstanding that it has been folded.
This is accomplished by blanking the structural member from cardboard or the like which is creased or scored to be folded longitudinally to a cross section such as to preclude transverse folding, the material also being transversely creased or scored in a manner to permit transverse folding only when the material is flat. In other words, the longitudinal fold is incompatible with the folding of the material on its transverse fold.
Thus, if the longitudinal fold is maintained in the structural member by means which preclude its parts from flattening out, the structural member will also be held in such a way as to preclude transverse folding.
In the various embodiments disclosed, the structural member is angular or triangular or square in cross section when erected but folds into flat form when collapsed to permit of folding on the transverse score line. In the disclosed embodiments, rubber bands encircle the faces of the structural member and subject such member to 'a bias such that as the structuralmember is erected, the
respective faces tend to spring to longitudinally folded positions in which they are incapable of yielding about their transverse score lines.
Various means are disclosed for holding the parts in the positions to which they are urged by the rubber bands.

In the device shown in FIGS. 1 to 3, the collapsible structural member 25 comprises a column which, as erected, is of angular cross section to include faces 26 and 27 foldably joined to each other at right angles upon a score line 28. At its upper end, the face 27 has an integral flange 29 joined to it upon a score line 30 and connected by adhesive 31 with a display panel 32. Immediately beneath the flange 29, the faces 26 and 27 are respectively notched at 33 and 34, the notches serving to position a rubber band 35 which encircles the two faces under tension. When the faces are flattened to the same plane as shown in FIG. 3, the tension of the rubber band 35 is increased. Consequently, whenever the faces 26 and 27 are free to fold upon the longitudinal score line or crease 28, the tension of the rubber band tends to draw them from the mutually planiform position of FIG. 3 to the angular relationship in which they are shown in FIGS. 1 and 2.
The faces are not free to fold along the score line 28 when they are folded intermediate their ends upon the transverse score line 37, as is the case in the showing of FIG. 3. In FIG. 3, the upper and lower ends of the respective faces 26 and 27 have been collapsed into superposed position on the transverse score line 37. Accord ingly, in order that the column may be erected to the position shown in FIGS. 1 and 2, it is first required that the upper and lower ends of faces 26 and 27 be unfolded so that the entire length of such faces lies in the same plane. Thereupon, the tension of the rubber band 35 will cause the faces to told about the longitudinal score line 23, such folding being incompatible with folding upon the transverse score line 37. Thus, when the faces are folded as shown in FIG. 1 and FIG. 2, they cannot fold on the transverse score line and the colurrm will stand erect.
In order that the column may be supported in its erect position, the lower ends of the faces 26 and 27 are desirably enlarged as shown at 38 and 39. Whether or not they are enlarged, each is desirably provided with a flap. The flap of face 26 is shown at 40 and the flap of face 27 is shown at 41. When the two faces are at right angles to each other as shown in FIG. 1 and FIG. 2, the flaps 4t) and 41 are superposed and a can such as is commonly used for foods or lubricating oils or the like may be placed on the superposed flaps as shown in dotted lines at 42, the can being representative of any weight which, placed on the superposed flaps, will anchor the base of the column to maintain the column erect to hold the panel 32 in display position.
The device shown in FIG. 4 to FIG. 6 is collapsed and erected like that of FIGS. 1 to 3. However, it has a different base and it has a display which is not integral with the structural column. Its structural member is designated by reference character 250. Like member 25, it has faces 26 and 27 integrally joined on a longitudinal fold line 28 and having a transverse fold line at 37. In other words, the generic concept involves collapsing them into parallel positions whether such positions involve the same plane or contiguous planes. In either case, they may be folded on a transverse fold line when in parallel positions, whereas they may not fold on a transverse fold line when they are non-parallel.
type of base. In this construction, the faces 26 and 27 have flaps 40 and 41 but, in use, they are folded outward- 1y away from each other as shown in dotted lines in FIGS. 4 and 6, instead of being folded into superposed position as in FIG. 1. The base member 45 is provided with the folded faces 26 and 27, and the flaps 40 and 41 are divergent beneath'the base member 45 to be confined between the base member and the floor. If the base member has substantial weight of its own, it, will not be necessary to use a can or other weight.
with an opening 46 which is dimensionally in conformity p In this instance, the erected column being square in 'cross section, a channel-shaped adaptor is used at 525 for the support of the panel'325 whose bow535 isconnected by staple 64 or otherwise to the adaptor.
I claim: I v V j 1. The combination with a display panel, of a support therefor comprising collapsible lightweight structural member comprising an elongated strip of material having a longitudinal fold line and faces at opposite sides A special display panelmounting is also disclosedin the construction of FIGS. 4-to 6. The faces 26 and 27 have notches at 48 and 49 which receive'the cut-out tabs 50 and 51 on a triangular adaptor 52 which is received telescopically'intothe angle between the faces 26 and of ,said fold line. which arehingedly movable upon said fold line with respect to each other between collapsed positions of substantial, parallelism and erected positions in which said faces are at an angle to each other, the said faces being respectively subdivided by aligned transverse fold lines upon which they are foldable in their collapsed positions of parallelism, but upon which they are not foldable when erected to positions in which they are 27. vThe adaptor is stapled or otherwise fastenedto the bowed stretcher 53 of a tensioned panel 320 which is marginally flanged-in accordance with the teaching of myv Patent No. 2,805,504.
Whereas the structural members'thus far disclosed rep-' resent openfigures in cross section, 'beingjmerely angles, the structural member 251 shown in FIGS. 7 and 8 has a closed triangular form in cross section, comprising not only the faces 26 and 27 integrally joined on a longitudinal fold line 28, but further comprising a third face 55 joined to the face 27 upon a longitudinal score line 56; :The
the structural member is erected as there illustrated. Yet,
. rubber'band now encircles all three faces, tending to hold them in the triangular form shown in FIG. 7 when if the several faces are provided with transversely aligned transverse score lines at 371', they may be folded on such transverse score line after firstbeing collapsed into parallelism as shown in FIG. 8. For this purpose, the rubber band 35 may either be removed or left in place. If left in place, it will be subjectedto'very substantially more tension than in the construction shown in FIGS. Ito 3.
The general arrangement of the base 451' with respect to the severalflaps 401, 411 and 412 is similar to that angularly' relatedto each other, and means carried by said strip'forzrendering said fa'ces self-erecting when portions of the respective saidaface's at opposite sides of the respective fold lines are aligned, said means comprising a rubber band entirely externally encircling said strip and under, greatertension in said collapsed position than in saiderectedposition for biasing said faces toward their angula 'rly related erected positions, said means being yieldable to accommodate movement of said faces to their collapsed positions of'substantial parallelism, said faces havingfflaps, and means connected with said flaps for maintaining said faces in the angular erected positions to'which they are biased by said rubber band.

In addition, there is a'fourth face 60 joined toface 555 upon a score line 61. Also, there is a gluing flap 62 con nected to the face 60 and integrally joined to the face 265 on a fold line 63. The concept of connecting the otherwise free margins of the faces is applicable to the construction of FIG. 7 in the same manner, as disclosed in FIG. 11 shows how the several faces may be collapsed into parallelplanes and thereupon are foldable on a transverse fold line 375 for. shipping or storage.
