Claims. (01. 40126) My present invention relates generally to displayldevices, and has particular-reference to an improved knock-down'arch display.

'It is a general object of the inventiontoprovide a display device which-is in theform of an arch'upon which suitable advertisingindicia may be printed or displayed; I -.:?A "more particular object is to provide a device which is composed entirely of simple struclO tural elements formed fromflat blanks of sheet cardboard or equivalent. material. The elemehts are so constructed that they may be readily' collapsed into substantially flat-condition, or setsupinto prismatic form. When set up, the

parts are adapted to be assembled in .an extremely simple manner, and with a minimum of'...efiort, into a rigid self-supporting structure.

. The present device may be of any'desired size,

butfonthepurpdse of explaining the general characteristics of the structure I will state that a satisfactory embodiment; for use on a display counter of. a store or in a show window, has:a

painof columnsapproximately three to four feet high, and a1 cross-beam approximately five feet 2 in 1ength '1' @Thepresentdevice consists essentially ofonly three main elements, 1 two of which are adapted to serve as upright spacedcolumnsfthe third of which is adapted toserVe as a cross-beam which rests upon the columns. 'Each of th'e elements maybe set upinto the form of'a hollow prism, andthe'term prism is used herein in a broad sense and is intended toinclude within its sc'ope'the configurations 'herein illustratively exemplified, in which the columns are'each of rectangular cross-section, having squared ends, while the cross-beam is of substantially rectan gular cross-section with arcuate ends. Y "I achievethe foregoing objects, and such other objects as ma'y' hereinafter appear "or be pointed o'ut,i in the manner illustratively exemplified in theiaccompanyingdrawings, wherein v 7 Figured is a perspective view of a knock-down display device of the present character, in.set-up n ion; r Y 4 Figure 2 is a cross sectional view taken substantially along' .the-.line.2..2 of Figurel';

Figure 7 is a plan view of a bracing disc for use with; the cross-beam; and

Figure 8 is a plan viewof .a bracing disc. for use with one of the columns. i

The. device consists essentially .of. the two spaced upright columns ill and II and thecrosse beam; l2. Each ofthe columns iscomposed of a single blank of sheet material, such as card.- board orthel like, folded upon itself to form a collapsible tubular structure. Since eachof the garments is identical with the other, a description of one will sufiice, f V

A substantially rectangular blank, as shown most clearly in Figure 6, is divided by. fold lines into rectangular sections I3 and-I l, with provision being made for an. attachmentflap l5 atone edge. When folded upon itself, the sec,- tions 13 are adapted to'form front and rear walls of the-resultant column; and the sections .14 are adapted to form side walls. The attachment flap l5 is .secured'byadhesive means or otherwise to the margin adjacent to the edge It, so that a tubular. structure results, having a substantially rectangular cross-section. Along the bottom rim of the structure tabs H are provided which, when folded outward, serve as feetto facilitate the support of thecolumn, as indicated most clearly in Figures 1 and 2. :If desired, tacks may be driven through these feet into the counter or floor upon which the device is. to stand.

Along the upper rim of the column I, provide upstanding ears I8, preferably one for eachwall,

and preferably, though not necessarily, centered with respect to each wall.

It will be obvious that each of the columns may be collapsed into substantiallyflat conditionby simply folding the same along, two diametrically opposed edges, thereby bringing the walls I3 and I4 into superposed relationship. On thev other hand,when the column is to be set up, it is a relatively simple matter to open it up into tubular form. Preferably, though not necessarilyue'ach column is braced in set-up condition, by inserting thereinto one or more bracing discs such as that shown in Figure 8 and designated by the reference numeral l9. This referencenumeral is applied to discs of this character in Figures 1-4.

Each of these discs is preferably of relatively rigid cardboard, such as corrugated board, and it has a medial opening 2i) which serves as a convenient hand wheel. Each disc conforms. in peripheral contour with the internal cross-sectionrofthe column, sov that when it is inserted its edge wedges itself against the inner wall of the column and thereby serves to hold the column in proper setup condition.

The cross-beam l2 may be composed of the blank shown most clearly in Figure 5. This blank is an integral piece of cardboard or equivalent, cut and shaped to define adjacent sections 2|, 22, 23, and 24, and provision is also made for an attachment flap 25. The section 2| is adapted to form the bottom wall of the cross-beam; the section 23 is adapted to form the top wall and is somewhat shorter in length than the bottom wall; and the sections 22 and 23 ultimately form the front and rear walls of the cross-beam.

At the opposite ends of the section 23 I provide flaps 26 which ultimately form openable end flaps for the beam. At the end of each flap I provide a connecting tab 27, and this tab is preferably of T-shape so that it may be inserted through a slot to lock the flap 26 in desired position.

The section 2| is provided with the series of slots 28 near one end, and the corresponding series of slots 29 near the other end, each setof slots being of such a size and of such a relative arrangement as to accommodate the upstanding ears I8 of one of the columns. Near the ends of the section 2| I provide the slots 30 which are adapted to receive the tabs 21. After the blank of Figure 5 has been properly cut and shaped, it is folded upon'itself and the attachment flap 25 is secured by adhesive means or otherwise to the margin of the edge 3|, thereby forming a tubular structure of substantially rectangular cross-section. This structure may obviously be collapsed into substantially flat condition in the same way as the columns are collapsible. The clot-and-dash lines 32 represent fold lines which constitute hinges for the flaps 28', and when the cross-beam is collapsed it is usually preferable to fold each flapZt along its corresponding hinge line 32, so that the flap will overlie the section 23.

The cross-beam is preferably maintained in setup condition with the aid of bracing discs of the character shown at 33 in Figure 7. These discs are similar to the discs l9 are provided with the central openings 34; and are preferably composed of corrugated board or similar rigid material. Each of the discs conforms in peripheral contour to the internal cross-section of the crossbeam.

When the device is set up, the two tubular columns are first erected and arranged in proper spaced relation. The cross-beam is then applied to the columns, so that the ears l8 of one column will enter into the slots 28, while the ears l8 of the other column will enter into the slots 29. V This act of assembly is greatly facilitated, in the present device, by the free access which is aiforded by swinging the flaps 26 rearwardly onto the top wall 23 of the cross-beams This is shown most clearly in Figure 4, in whichthe dot-and-daSh lines 26 represent the flap 26 in rearwardly swung position.

tion to the dot-and-dash line position 26' of Figure 4, and back again, the outer edge swings through an arc which is approximately designated by the dot-and-dash lines 35 in Figure 4.

It will be observed that when the device is completely set up the openable end walls or flaps 26 are completely concealed from the front and rear. This arises from the fact that the front and rear walls 22 and 24 of the cross-beam have extensions 36 shown most clearly in Figures 1 and 4 which conceal the edges of the flaps 26. The flaps 26 are preferably of such a size that when they are in closed position they .lie along an are as shown in Figure 4. The end extensions 36 of the front and rear walls of the cross-beam are preferably of a similar contour, but, obviously, other shapes may be employed if desired.

When the structure is used, it may be rested or secured upon a store counter or upon the floor, or it may be placed'in a store window-"or other desired location. With suitable advertising ornamentation on the columns and onthe cross-beam, an attractive attention-arresting device results. In many cases, it is preferable to arrangea display of the commodities that are advertised around the columns land under the arch; or they maybe ornamentally stacked adjacent to each of the columns. Some may often be rested upon the cross-beam, provided that'the weight is not too great.

The, disassembly of the device, after it has been used for the desired'period of time, is'ju'st assimple as its assembly. The steps hereinbefore described are carried out in reverse order, and the various elements are adapted to be stacked, shipped, or stored'in substantially flat relationship. If desired, all of the elements may be completely discarded after the device has been used, because the structure is so simple and economical in nature'that salvaging of the parts is not essential. In fact, one of" the characterizing features of the present structure lies in the utter simplicity thereof, whereby an emtire display device is provided by employing'only three main elements, each of which is nothing more than a' blank of sheet cardboard properly shaped and constructed.

It may be noted in passing that the ease with which'the parts are assembled and disassembled is due in large measure to the novel arrangement of end flaps; whereby each flap is hinged to the top wall of the cross-beam along a hinge axis 32 which is ofiset'toward the center of the beam.

In general, it will be understood that changes in the details, herein described and illustrated for the purpose of explaining the nature of my invention, may be made by those skilled in the art without departing from the spirit and-scope of the invention as expressed in the appended claims. It is, therefore, intended that these details be interpreted as illustrative, and notin a limiting sense.

Having thus described my invention, and illustrated its use, what I claim as new and desire to secure by Letters Patent is 1. A knockdown display device comprising a pair of columns and a cross-beam, each of said elements comprising a blank of sheet cardboard shaped into the form of a hollow prism which is collapsible into substantially flat conditionand means for separably interlocking said prismsto form an arch in which the columns serve as spaced upright supports for said cross-beam,

said means comprising upwardly projecting ears on the upper rims of said columns, and slots in the bottom wall of the beam arranged to receive said ears, respectively, whereby the beam rests directly upon the upper ends of said columns.

2. A knockdown display device, as set forth in claim 1, in which the beam has end walls in the form of openable flaps to permit access to the interior of the beam during the engagement of said ears into said slots.

3. A knockdown display device comprising a pair of columns and a cross-beam, each of said elements comprising a blank of sheet cardboard shaped into the form of a hollow prism which is collapsible into substantially flat condition, and means for separably interlocking said prisms to form an arch in which the columns serve as spaced upright supports for said cross-beam, said means comprising upwardly projecting ears on the upper rims of said columns, and slots in the bottom wall of the beam arranged to receive said ears, respectively, whereby the beam rests directly upon the upper ends of said columns, said beam having end walls in the form of openable flaps, and the front and rear walls of the beam having end extensions concealing the edges of said flaps.

4. A knockdown display device, as set forth in claim 1, in which the beam has end walls in the form of openable flaps, each flap being hinged to the top wall of the beam, and means for separably interengaging the free end of each flap in the bottom wall of the beam.

5, A knockdown display device, as set forth in claim 1, in which the beam has end walls in the form of openable flaps, each flap being hinged to the top wall of the beam along a hinge axis offset toward the center of the beam, and means for separably interengaging the free end of each flap with the bottom wall of the beam, whereby top access to the column ears is facilitated when the flap is swung upwardly.
