A further object of the invention is in the provision of improved means for holding the frame parts together at the corners and in rounded or curved distended position.
A still further object of the invention is in the provisionof a frame structure of this kind which is capable of great variation in curved, angular or rounded simulation of various actual picture frames.
A still further object of the invention is in the provision of afolding display of this kind which may be easily set up and supported in vertical position, either upon any suitable plane or by hanging it as a picture, and also collapsible when not in use tofold compactly for shipping purposes and for storing them in quantities.
Other objects of the invention will appear hereinafter, the preferred structure and modifications thereof being more particularly illustrated in the accompanying drawing, in which Fig. 1 is a face view or elevation of a frame in accordance with this invention;

Fig. 6 illustrates a modification of the curved frame in which no additional supporting struc-. ture is used; and t Fig. 7 to 16 inclusive are fragmentary sectional views illustrative of a number of different frame structures capable of use and contemplated in connection with a display frame of this kind.
In simulating a picture frame for display purpose made' of cardboard, one diiiicultyis to hold the frame tightly at the corners and another dimculty is to produce a rounded or curved frame which will not crack or break. In producing a curved displayframe of cardboard or similar material having substantial thickness so' material such as of one" that itwill have the necessary rigidity, the material may be scored or creased to produce an angle orbend but must have an entirely different treatment to produce a curved or rounded portion without breaking or cracking. In the pres-. ent invention the rounded feature of the frame is produced by providing a number of parallel scores or cuts extending partially but not entirely through the material so that the surface opposite the scores may be bent without breaking. This is particularly advantageous for display frames for advertising material where a.
printed sheet of paper is applied to one surface of a cardboard sheet, the printed sheet bearing a picture as well as a frame representation, all of which is printed so that upon being properly cut and scored the desired frame and picture will be incorporated as a complete display when the frame structure is distended.
Referring now more particularly to the drawing, a display frame is made of a single sheet of cardboard 20 or the like, cut, scored, distended and held to form a central picture plane 2| and a simulation of side and end curved frame sections 22 and 23 with an inner beveled edge 24 connecting them to the picture plane.
In order to bend, curve or bow the portions forming the frame for the display without breaking the cardboard on the face thereof, the under or opposite side of the sheet is provided with a plurality'of parallel closely spaced scores 25 extending partially but not entirely through the cardboard and forming parallel 'fold lines therein which permit the portion thus scored or cut to be bowed or bent transversely. to the scoring thereof and providing a relatively smooth curved surface convex or concave -on the side opposite such scoring.- At the corners dividing the sides and ends are curved cuts 26 depending upon the countour or shape ofthe frame desired, these cuts providing an angular beveled juncture 21 at each corner and one extremity 28 overlapping the other at the rear side of the corner as clearly shown in Fig. 2.
In the form shown by Figs. 1 to 5 a bevele connecting portion '24 is produced by score lines 29 and 30 in opposite'faces .thereof and at the extremities of the sidesor, ends this necessitates a V-shapednotch 3| in/order to make a tight connection.
To hold the sides of th frame distended in the desired position, a locking device, also preferably formed of cardboard, has a corner portion- 32 at each end and flat portions 32a between the ends adhesively secured to the back of the picture plane 2| and preferably adjacent each comer it 1 by an extension 35 hinged to the portions 32 C structure it will be readily understood that itmay and 32a adhesively secured to the back plate, forming a continuation of the end locking wings 34 and the extension having a hinged and overlapping. locking tongue 36 extending all along one side of the frame with perforated slots 31 therein at intervals to receive locking tongues 38 which project therethrough from the locking tongues 33 all along the corresponding side of the display. Thus the two end locking tongues 33 and 34 are held rigidly in position at the back of the picture plate and the outer end of each locking tongue 33 or 34 which projects beyond the picture plane and at the back of the frame is provided with another locking tongue 39 which engages in a locking slot 40 in the outer edge of the frame side or end beyond the parallel score lines 25,
65 through engaging slots'45 to receive them so that Thus the shape of the locking tongue is depend,- ent upon the shape of frame desired, the shape of the outer head or projection of the locking tongue forming a backing for distending and supporting the frame section of the desired shape produced by the frame scoring. For some frames only the end locking tongues are necessary but if the frames are long, additional locking tongues may be provided along the sides or ends, depending upon the direction of extent of the locking device on the back of the frame. The locking device also produces a box-like supporting structure because of the overlapping engagement of the hinged portions 35 and 36 which produces a very strong and well braced frame structure.
In extending a frame of this kind the locking wing structure is first set up from its fiat or collapsed condition at the back of the picture frame 'and then the two opposite sides or ends separately are connected to their corresponding locking wings, after which the other. two ends or sides are separately folded over, engaging their corresponding locking wings and overlapping the ad.- jacentsides or ends at the corners. designing the corner cuts 26 conforming to the shape of the frame desired,,the comers willflt tightly and are held tightly in place by engagement of the tongues 39.
The curved portion of a frame may be formed at the edge of a picture plane 40 made of cardboard and the like as shown in Fig. .6, by bending over each of the edges inwardly upon a score line 4|, by providing the face opposite the picture plane with parallel scores 42 so that the reverse face 43 of this edge is bent or curved as desired, the outer marginof this bent edge being formed with tongues 44 which are insertedthe outwardly bent frame portions will thereby be held about the edges of the picture plane 43' to form the resemblance of apicture or display.
.One objection to this form is that the exposed other forms shown the printed sheet including --the frame and the picture display in the frame are printed on one 'sheet. This frame however shows a simple form of the parallel scoring as applied to simulate a curved or rounded surface,
, and eliminates the rear distending and supporting structure.
Instead of applyingthe back supporting structure simply to the extension of a curved frame y p pe l also be applied to a straight, angular box-like frame either separately or in conjunction with curved sections, either bent convexl'y or concavely. A few representative frame sections are illustrated in Figs. '7 to 16, inclusive, Fig. 7 showing a straight riser 5| from the picture plane and a curved outer edge 52; Fig. 8 shows a rolled edge-or a rounded continuation 53 of the picture plane; Fig. 9 shows an angular straight edge 54'rearwardly from the picture plane; Fig. 10 shows a raised round convex edge 55; Fig. 11 shows a raised angular beveled edge 56; Fig. 12 shows a raised rectangular edge 51; Fig. 13 shows a concave frame edge 53; Fig. 14 shows a forward angular projection 59; Fig. 15 shows a concave edge 60 back of the picture plane edge; and Fig.
16 shows a concave forwardly extending curve 6| at the margin of the picture plane.
Picture or display frames of the kinds'illustrated and other variationsof straight and curved portions are all intended to be distended and held in frame position by the frame holding structure parts, whereupon the frame sections may be extended flatly or folded over inwardly upon the picture plane. Likewise the locking wings 33 being disengaged may be folded flatly with the extension .35 and locking flange 36 at the back of the picture plane.
