NEW JERSEY, A CORPORATION OF NEW STAND FOR POSTERS.

Application filed May 4,

This invention relates particularly to display posters which are made up in flexible form so that they can be rolled for shipment or storage purposes.

Various attempts have been made to provide some sort of light simple frame for supporting such posters unrolled, in display condition, but these efforts have not been entirely successful.

The objects of this invention are to provide a supporting structure combined with the poster so as to occupy but small space when the poster is folded, capable of being quickly set up to support the poster in extended relation and whichwill be simple, light, inexpensive and satisfactory in all respects.

These objects are attained in the particular embodiment of the invention'herein dis closed by constructing the poster with edge reinforclng strips and supporting the same in extended relation by braces or uprights connected with the edge reinforcements, said braces being crossed at the back of the poster and having an extensible prop flexibly connected therewith at the point'of such cross lfarious other novel features of the invention will appear as the specification pro: ceeds.

v In the drawings accompanying and form- 'in part of this specificatiomthe invention is illustrated embodied in different practical commercial forms, but it should be under stood that the structure may be modified with respect to such disclosure without departure from the broad spirit and scope of the invention. I

Figure 1 is a rear view of the poster un folded and set up for display.

Figure 2 is a view showing the frame folded and the poster ready to-be rolled about the same.

Figure 3 is an enlarged broken detail of f the resilient mounting for the prop;

Figures 4 and 5 are similar details of. modifications.

Figures 6 and 7 are views-of a further modification of the spring mounting.

The body of the poster is shown made of a sheet 5 of suitable flexible material having 1525. Serial No. 27,916.

edge reinforcing strips 6,7, at the upper and lower edges of the same.

The crossed braces are designated 8 and 9 and are shown detachably connected with the upper reinforcement-strip by paper fastener cllps 10 passed throughv registering openings 11 in the edge strip and upper ends of the supports respectively.

The supports are pivotally connected at the point of crossing by a stud 12 shown in the form of a split rivet engaged over bear- 1ng washers 13,14 at its opposite ends.

The pivot stud serves an additional function in the illustration in that it is extended. through the upper end of the prop 15 and acts as a pivotal mounting for the same.

The angle at which the prop extends from the back of the supports is determined by bevehng the upper end of the prop at 16 to provide an angled bearing for flat engagement with the back of the rearmost brace, 9.

The prop is automatically extended and resilientl held at the angle determined by the beve ed upper end of the same, by spring means, here disclosed as a bowed spring 17 interposed between the two supports 8, 9 and held in this position bythe passage of'the pivot pin therethrough. The action of this spring will be best understood from Figure 3 Where it will be, seen that it exerts its force to separate the crossed braces or supports and to draw the beveled end of the prop flat against the back of the rear support, thereby retaining the braces in their crossed relation and the prop in its extended position. The pivot opening 18 in the. end of the prop is of sufficient size to permit the prop being folded down flat against the back of the rear support, as indicated in Figure 2.

To hold the poster stretched flat over the supportingframe, elastic bands are shown provided at 19 secured on the back of the supports by staples 20 and looped over the extended ends of the lower edge reinforcement. These resilient connectors hold the poster taut and by so doing, act .to brace the entire structure.

The supports. and prop may be made of light strips of wood and the Whole structure may be made quite light since the parts are poster sheet caught th-erebetween.

so interconnected and tensioned as to brace eachother. This braced construction imparts to the poster the characteristics of a light rigid panel, which can be shifted and handled as if it were a one piece unit.

The edge reinforcements may be made of half round strips secured together with the These strips when applied to the face of the sup porting braces serve to space the sheet slightly in front of such supports so that it can i about the lower ends of the braces and about the lower end of the prop to hold these parts inclosely folded relation, By a reverse set of operations, the poster can be quickly set up, the spring pivot between the braces and prop materially assisting by holding the braces in their angularly crossed relation while the upper edge of the poster is being attached to the upper end of the free brace and by automatically thrusting out the prop into extended position where it isready to support the poster as soon as it is swung to an intermediate position between the lower ends of the braces.

The formof the spring for tensioning the parts and automatically throwingthe prop into supporting position, may vary both in structure and location. Thus in Figure 4, the spring 17 is of the coiled type and is located at the back of the beveled portion of the prop, exerting .its pressureto force such beveled end forwardly into flat engagement with the back of thercar brace.

In Figure 5, the spring is shown as a rod or wire 17 of spring steel or the like embedded at its lower end in the material of the prop and having its upper end caught in the loop of the cotter pin 12 which forms the center pivot. This spring has both the effect of forcing the beveled end of the prop forwardly against the back of the rear brace and of swinging the lower portion of the.

prop out into the supportin position.

In the form of. the invention illustrated in Figures 6 and 7, the spring effect is obtained by elastic strips 17 connected between a pin 21 on the back of the rop below the pivot stud and pins 22 on tie outer sides of the crossed braces. It will be seen that the com bined ffect of these resilient connectors,

which may be elastic bands or coiled springs,-

memos is to swing the braces open and to pull the prop" rearward into a centralized supporting position with the beveled end thrust flat against the back of the rear brace. The spring means in this instance thus has the effect of holding the three members of the supporting tripod in their extended relation.

To limit the extent of this spreading action some confining means may be provided such as the cord shown at 23 connected between the three legs of the tripod. This cord does not interfere with the folding of the frame, which can be done by simply swinging the parts together into the compact bundle shown in Figure 7, and it comes into action automatically to limit the spreading tendency when the tripod elements are released from their bundled or folded condition. This last tripod structure has the ad'- vantage over the first forms described, that the natural-tendency of the spring means is to spread the legs and thus automatically set up the tripod, leaving the operator only to properly connect the poster sheet to the tops and bottoms of the crossed braces. The pivot connecting the prop and the two braces is shown in this form of the invention as a wood screw 12 extending freely through openings in the prop and rear brace into a seat in the front brace.
