EASEL Filed Juhe 23, 1939 Patented Au 12, 1941 UNITED fiTATES, PATENT. OFFICE EASEL' Milton Kohn, Chicago, 111.

Application June 23, 1939, Serial No. 286,786

(01. its-124.1)

15 Claims.

This invention relates to easels and more particularly to easels made of flexible sheet material for the purpose of supporting display cards or photographs or the like.

One embodiment of the invention is particularly adapted for use as a place card or for similar purposes. It is an object of the invention to provide an easel or card of the character described which is normally collapsed and may be opened or expanded to easel form and in which automatic locking means is provided for retaining the easel in self supporting condition.

A further object is to provide an easel of the character described which may be formed of ordinary cardboard or similar comparatively thin sheet material; also, in which substantially the entire easel may, if desired, be formed of a single piece of sheet material, and in which all of the smaller and more fragile portions thereof are enclosed within the protecting sheets when the easel is collapsed.

An important object of the invention is the provision of a type of hinge between the front of the easel and the supporting means which will provide a substantial spring tension tending to collapse the easel, and which also tends to resiliently retain the locking means in place when the easel is expanded.

A further object is to provide an easel of the character described which will be of few parts,

cheap to manufacture, easy to assemble, and which will not easily get out of order in use; also wherein the easel isautoma'tically locked in open position by a single manual operation.

Further objects will be apparent from the specification and the appended claims.

Fig. 3 is a side view illustrating the easel in its normal collapsed condition.

, "Fig. 4 is'an enlarged view of the upper end of the easel'and illustrates the novel hinge arrangement.

Fig. 5 is a view of the blank from which the main'portion of the easel may be formed, a portion being broken away for convenience in illustration.

Fig. 6 is a rear perspective View of another embodiment of the invention.

Fig. 7 is a side elevation of the embodiment shown in Fig. .6 in its collapsed form.

Fig. 8 is a perspective view of the'blank fonning the supporting portion of the embodiment shown in Figs. 6 and '7 with thehinge members attached thereto.

' Referring to the drawing in detail, theembodiment illustrated in Figs. 1 to 5, inclusive,

comprises two display panels I and 2 and an intermediate portion 3 connecting the lower edge ofthe walls or panels I and 2. The panels I and 2 and the intermediate portion 3 are preferably formed of asingle piece of cardboard or other suitable resilient sheet material, and the blank may be scored, as shown by the dotted lines 4 and 5 in Fig. 5, to provide hinge joints connecting the intermediate portions with the panels and a hinge joint 5 preferably on the median line of the intermediate portion 3, as shown, so that the intermediate portion 3 will normally tend to fold inwardly in the form of an accordion plait when-the easel is collapsed as shown in Fig. 3. The intermediate portion 3, therefore, provides two inwardly extending hinge members 6 and I which are hinged at their outer ends to the panels I and 2 with their inner edges hinged together as shown.

In the embodiment illustrated, the portion 1 adjacent the panel I of the easel is sheared as shown in Fig. 5 to provide tongues 8 which form integral extensions of the portion 6 and these tongues normally remain in substantially the same plane as the member 6 and merely form semi-rigid inwardly extending continuations thereof. The tongues 8 normally ext-end upwardly between the side Walls of the easel when it is collapsed as shown in Fig. 3, and, when the walls I and 2 are expanded, the ends of the tongues will move downwardly along the inner surface of the front wall as the accordion plait expands until the ends of the tongues automatically engage in slots 9 in the front wall of the easel, as shown in Fig. 1, to thereby lock the easel in open position.

lower edge supported on the outwardly extending ends of the tongues 8.

The upper ends of the panels I and 2 are secured together by means of a hinge member [2.

This hinge may be in the form of a folded strip of adhesive tape or any suitable material, preferably paper tape, which is adhesively secured to the side walls in the manner shown in Fig. 4, with the upper or pivotal edge of the hinge somewhat below the upper edge of the walls I and 2. In other words, the upper edges of the panels I and 2 extend somewhat beyond the pivot point of the hinge so that these walls tend to resist the opening of the easel and a resilient structure is thereby formed which normally tends to collapse the easel, and, when the easel is pulled open against this tension, the ends of the tongues 8 will move downwardly along the inner surface of the panel I until they automatically snap into the slots 9 and the normal tension supplied by the hinge will tend to hold the easel in the locked position shown.

The panel I of the easel may be provided with .a plurality of vertically aligned transverse slots 9 so that the tongues 8 may be engaged in any selected pair of slots to thereby provide supports for any desired size of card or photograph. It will, of course, be understood that either or both of the panels may bear illustrations or printed matter for display purposes.

The embodiment illustrated in Figs. 6, 7, and 8 is very similar to that previously described except that any suitable card l3 may be used for the front of the easel and a strap-like supporting member M is provided adjacent its upper end with a hinge I5 which may be similar to the hinge l2. The upper pivotal edge of this hinge I5 is positioned slightly below the upper end of the strap member M so that, when the strap and the card A3 are secured together by the hinge, the supporting member tends to collapse as shown in Fig. '7.

The lower end of the strap member M is secured to the card I3 by means of a hinge member [6 which may be similar to the hinge member 15; that is, it may be formed of a folded strip of adhesive tape having one side secured to the member l4 and the other side secured to the card Hi to provide a suitable hinge It. This lower pivotal edge of the hinge It may be positioned slightlyabove so that this hinge also tends to resiliently resist opening of the easel.

The strap member rl l' may be transversely creased or scored or otherwise formed along lines corresponding to the dotted lines ll and E8 to provide a collapsible accordion hinge portion H], as shown, whereby this entire hinge section tends to collapse between the body portion 14 and the card l3 when the easel is closed, as shown in Fig. '7. The construction of the accordion hinge portion it in this embodiment is similar to the intermediate collapsible portion 3 of the easel previously described except that in this structure any suitable card or panel 13 may be used and the supporting portion or strap it may be attached thereto by means of the hinge members 15 and it.

The position of the pivotal point of the hinges l5, and H5 in the relationship shown at 20 in Fig. 7 causes the resilience of the supporting member to tend at all times to collapse the easel and to hold it rigidly in position when opened, as shown in Fig. 6.

Thestrap portion Hi is sheared and slotted as shown, in Fig. 8 to provide a locking tongue 2|. The tongue 2! forms an integral portion of one side of the accordion hinge member l9 and automatically engages in a slot 23 in the strap Hi when the easel is opened, as shown in Fig. 6. In this embodiment the strap portion Hi, including the adhesive tape hinge members l5 and 16 applied thereto, may be manufactured and sold as a separate unit and may be attached to any suitable card such as the card l3 by merely securing the free ends of the adhesive hinges l5 and I5 thereto as shown in Fig. 6.

Modifications may be made without departing from the spirit of the invention, and it is therefore desired that the invention be limited only by the prior art and the scope of the appended claims.

Having thus described this invention, what is claimed and desired to be secured by Letters Patent is:
