17 Claims.

This invention relates to display devices which are readily placed in condition to be conveniently packed for shipment or storage and may be easily but simply placed in display condition.

The main object of the invention is to provide a device of the character described which is of simple construction and low in cost.

A further object of the invention is to provide a device of the character described which shall be self-contained, requiring no auxiliary apparatus or fittings to support it or otherwise make it operable for display purposes.

A further object of the invention is to provide a device of the character described corn-prising a display surface held in a flat position in connection with a simple support which not only maintains the display surface in an upright position but also maintains it under tension, so that it will be flat and smooth without ripples or wrinkles.

It is a further object of the invention to provide a device of the character described which does not require pasting, gluing or any similar operation to change the device from its flat sheet or manufacturing and packing position into a condition for use.

It is a further object of the invention to provide a device of the character described wherein the display surface is formed by a flexible material incapable of self-support such as oil silk or paper or other suitable material.

A further object of the invention is to provide a device of the character described requiring only two parts for the display and its support, one part being a card of any material suitable for the purpose and the other the display surface.

One of the main objects of the invention is inexpensively (1) to stretch taut and smooth without ripples or wrinkles a flexible material incapable of self-support, (2) to erect such material simply and easily in upright display position and (3) to manufacture, ship and store a display device in flat condition.

Other and ancillary objects of the invention will appear hereinafter.

In the accompanying drawing which illustrates the invention- Fig. 1 illustrates a perspective front view of my display device, when in an operative condition or condition for use;

Fig. 2 shows a perspective rear View I of the device shown in Fig. 1;

Fig. 3 illustrates a top view of my display device when in a flat or leveled condition, as used for the purpose of manufacture, packing and ship- Figs. 4 and 5 show the top view of the device in two difierent stages of development during the process of transforming the device from the flat condition to that shown in Figs. 1 and 2;

Fig. 6 is a top view of the display device when in a condition as that shown in Fig. 1;

Fig. '7 is a sectional top view of a lock arrangement on line ll of Fig. 2; and

Fig. 8 is a plan view of the card used in the display device.

Referring to the drawing, the suitably elastic card or sheet of pasteboard or cardboard is, Fig. 8, is provided with two scored lines 5 5, extending throughout the entire length and located a deflnite distance away from, two parallel edges of the card. The strips or flanges 12, thus produced, may consequently be subjected to a hinging or bending action with relation to the remainder of the card, so that these flanges may be moved and turned on its scored line in either direction, from front (the side of the display sheet) to rear and vice versa. When the flanges are turned on their hinges or scored lines into their extreme forward position, they will lie against 'the front surface of the card It) in the manner shown in Fi 3.

When the card [0 is in a condition as that shown in Fig. 3, wherein the flanges l2 are turned against the front surface of the card, the visible and non-touching surfaces of both flanges are covered by a display sheet E5 of fabric preferably textile fabric, such as oil silk or the like and of which its size is approximately that of the bent card. This sheet, which may have printed or painted on its surface suitable advertising or other matter, is fastened to the outer surfaces of flanges l2 by any suitable means such an adhesive material or stapling or other fastening means.

The display sheet may, instead of having pictures, printing or other matter, serve as a picture screen for receiving light projected pictures or other matter as from a stereoptican or moving picture projector.

Card ID is also provided with a series of curvilinear slits l3, Fig. 8, located near to and in parallel alignment with the scores II on this card. These slits, made for the purpose of furnishing flaps or tabs M, are here shown to number three per series. It is evident, however, that this number may be changed, and that furthermore the distance between the flaps l4 may be determined to suit any practical conditions.

, The device thus far described may be changed from the flatcondition as shown in Fig. 3, as

used for shipping, into an operative condition, as that used for manufacturing and display purposes and which will now be described, referring to Figs. 3, l, 5 and 6, as follows:

The operator, holding the flat device of Fig. 3 in both his hands, will place his fore-fingers between the card I0 and the sheet l5 and separate the flanges 12 from the card. This will exert a tension on the fabric of sheet I5 and also cause a bulge or bow on the card in a direction away from the sheet. When the flanges have been turned far enough, the card will have a curvilinear shape as that shown in Fig. 4.

If now the flanges are turned still further away from the front surface of the card, into the position as shown in Fig. 5, the fabric will have been shortened still further relative to the card surface and the rounding or bowing of the card is subsequently increased still more.

By moving the flanges far enough, until they are stopped by the rear surface of the card, as shown in Fig. 6, the card will have received a maximum degree in curvature, large enough, to exert sufficient tension on the display sheet to hold it taut and smooth, and provide a large enough area within the bowed end to provide a base on which the device may stand firmly and stably.

When in their rearward position as shown in Fig. 6, the flanges or strips I2 may be secured or locked in that position by being inserted beneath the flaps H (see Figs. 2, 6 and 7) so that the device will be held in display position.

It will be apparent that the wider the strips l2 the more the card will be bowed for a given angular movement of the strips about their hinges, so that the tension upon the display sheet I5 and the bowing of the card may be regulated by regulating the width of the flanges.

It will now be seen that the present invention provides a display device which is extremely simple in its structural details and which, by an easy manipulation and method of procedure, can be converted from a flat, or shipping, condition into one wherein it is applicable for practical and effective use without the necessity of any auxiliary apparatus for supporting it or otherwise.

While the card [8 is shown as being imperiorate, it may be provided with openings or windows through which may be projected the light from a picture projector whereby an image may be formed upon the screen or display sheet l5.

If desired an incandescent lamp I6 or other suitable illuminating means may be placed in the space between the bowed card and the display sheet for the purpose of illuminating the latter.

While the invention has been illustrated in what are considered its best applications it may have other embodiments without departing from its spirit and is not therefore limited to the structures shown in the drawing.

What I claim is:
