' 9 Claims. (01. 40-125) Theinve'ntion relates to a collapsible display 'device. of the type in which a length of flexible material is adapted to be-rolled orwrapped about a rod or roller to constitute a compact construction, economizing in space for storing and transportation and which can be readily distended with the flexible material stretched taut. The primary object of the invention is to provide'a simplified form of construction of the type outlined which will feature a-high degree of compactness; the utilization of the least possible amount of material and at the same time to give the requisite structural strength to the construc:

tion'asawhole.

Still another object of the'invention and still featuring compactness in construction is to-pro. vide a simple means for bracing the structure against distorting strainsand to provide for a wide spreading form of base support for-holding thestretched material in upright position. 7

Various other objects and advantages of the invention-will be in part obvious from an in- 'spectionz of-the accompanying-drawing andin part will be more fullyset forth in the following. particular description of one form of mechanism embodying thetinvention, and the invention also consists in certain new and novel feaftures of: construction and combination of parts hereinafter set forth and claimed.

Inthe accompanying drawing: Fig. '1 is a view in rear elevation showing a preferred embodiment; of the invention distended to sh'owrit in its operative position and with the parts broken away; 1

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. land lookingin the direction indicated by the arrows; c 1 Fig. 3 is a detailed sectional view taken on the line 33 of Fig.' 2 and=showing the stretcher about to be slid into the roller bar; and

Fig. 4 is a view in elevation of the structure shownin the preceding'figures rolled in collapsed and housed position.

Referring to the drawing there is disclosed a .length 10 of flexible material which may be paper,

one side 12 of which is flatand to this flat side is permanently secured as by gluing or tacking the/upper edge of the material 10.- I

At the lower edge of the material 10 there is secured a similar brace for giving rigidity to this portion of the fabric. This brace, hereinafter referred to as roller 13, is of somewhat elliptical form as shown in Fig. 2 with a fiat side 14 to which the lower edge of the fabric -10 is secured. Atthe central portion of the underside of the brace 11 there is provided a socket 15 and similarly .theroller 13 is provided with an oppositing socket 165. A stretcher 1'7. is positioned-with its opposite ends inserted respectively in the sockets 15 and lfi and the parts are so proportioned that the stretcher will hold the flexible material-taut when in the distended position shown in Figs. 1 and 2. The stretcher is formed of two parts, a tubular part 18 and a rod 19; the rod 19 being provided adjacent one end with a collar 20 and positioned between the collar 20 and a bead 21 formed on the adjacent end of the tube 18 is a distendable spring 22. It will be noted from the construction as shown in Figs. 1 and 2 that the spring 22 acts to, force the parts 18 and 19 in opposite direction thus placing the flexible material 10 under spring tension.. The stretcher is so arranged that when the parts 18 and;19 have been demountedfrom each other the long upper portion 23 of rod 19 may be reversed from the position shown in Fig. 1 and telescoped within the open end of tube 18 so that the telescoped parts are reduced in length and the partsare so proportioned that when so telescoped they may be contained within the bore 24 which extends axially .through the roller 13. Y,

1 To one 'side of' the bore the portion of the rolleropposite the flat side 14 is provided with a groove 23 in which is contained or at least partially contained a foot 26, the end adjacent the socket 16 being pivotally mounted in place on pin 27. Instead of this pivotal mounting of the foot 26, it is obviously within the scope of the disclosure to providea transverselyextending bore or socket 28 indicated in dotted lines in Fig. 2 into which the end of the foot may be positioned with a friction tight fit when it is desired'to have the 'foot extend laterally from the roller to obtain the wide spreading support to the device as a-whole as indicated in the showing in Fig. 1. V I

In operation and assuming the parts to be in the position as shown in Fig. 1, itisapparent that the flexible material 10 is stretched taut in its plane to expose the characters on its front side and that when so positioned the material 10 acts to conceal its bracing parts positioned at .the rear of the material. There will usually be sufficient play in the flexible material to permit the removal oi-the stretcher 17 and for this purpose it is noted that the socket 15 is comparatively shallow. Should difliculty be experienced in removing the stretcher, it is simply necessary to hold two parts of the same and by moving the parts towards each other and against the resistance of the spring 22, one or the other end of the stretcher may be readily removed from its associated socket. When the stretcher is dismounted, the foot 26 is either swung back into position housed within the groove 25 or, in case the socket form of support is provided for the foot, it is simply withdrawn longitudinally from the associated socket at 28 and positioned in the groove 25. The two parts of the stretcher are then separated, reversed and retelescoped as hereinbefore indicated and the telescoped assembly is then inserted in the bore 24, as indicated in Fig. 3. The length of flexible material 10 is then wrapped about the roller in the manner of a shade roller as shown in Fig. 4 and preferably the parts are so proportioned that the flat side 12 of the upper brace 11 will face with the flat side 14 of the roller 13 so that there is finally obtained the smooth, somewhat elliptical wrapped construction shown in Fig. 4 and which may be readily contained in a mailing tube or other container.

By means of a device of this character it is possible to provide a form of display device which can be made much larger than similar construe tions now known; which will have a neat, substantially rigid appearance when distended into stretched position and which can be provided with a long supporting foot which will tend materially to one side to maintain the structure supported in its upright display position. When rolled for storage or transportation, there is presented a neat package without projections which might catch in other articles with similar projections and there is provided a structure which can be easily handled and quickly mounted in position thus providing an article which is particularly adapted for lecture and other purposes where difierent charts and display matter have to be quickly set and dismounted, one after the other.

The present disclosure particularly features a structure which when in wrapped position is entirely self-contained and forms a compact package.
