DISPLAY DEVICE The present invention relates to a multiple use display device. As will be seen from the description to follow the display device of the invention may be used, for example, for displaying advertising material, portraits, scenic representations, promotional renditions and the like.

Promotional exhibits for advertising purposes are customarily displayed within ready view and reach of the observer. Generally the display is supported within a longitudinal recess provided in the top surface of a supporting base having a width and length sufficient to sustain the display in erected position. With such support the display exhibit is exposed to handling and may be readily removed by individuals seeking souveniers. Because of its exposure it may also be marred by scribbling and other form of graffito.

The present invention is broadly directed to a display device which may be readily assembled and which, when assembled, will enclose the display to avoid marring or undesired removal thereof.

With the foregoing in mind, I provide in accordance with the invention a display device comprising a pair of members each constituted of an upstanding section and a base portion offset from said upstanding section, and longitudinally spaced apart means integral with the upstanding section of. each member, said spaced apart means interconnecting said pair of members with the upstanding sections in normal contiguous and aligned relation and with said base portions offset in opposite directions in relation to the upstanding sections, at least one of said upstanding sections being light transmitting, said contiguous and aligned sections being adapted,

upon simultaneous application of a downward manual force upon each of the offset sections, for separation a distance sufficient to permit insertion of a display between said members.

Advantageously, the longitudinally spaced apart means are formed in the upstanding section of each member adjacent the base portion and comprise a projection and a slot in substantial longitudinal alignment.

reversely related to the other member and the projec-' tion on one of the members fitted in the slot of the other member and the projection of the other member fitted in the slot of said one of said members.

Advantageously, both upstanding sections may be constituted of clear plastic material in which event two displays may be used, one for viewing on one side of the display device through one of clear plastic sections, and

the other for viewing on theopposite side of the display device through the other clear plastic section. While the base portion need not be made of clear transparent material and for that matter can be of a material other than that consituting the upstanding sections of the display device, it is desirable that the base be formed of the same material for ease of fabrication.

The members, constituting in their assembled relation the display device of the invention, may have any desired shape and may be produced by injection molding techniques well known to those skilled in the art.

With the display device assembled as indicated, in order to insert a display between the two contiguous and aligned upstanding sections of each member, it is only necessary to simultaneously exert downwardly applied finger pressure on the base portions of each member whereby to spread apart each section a distance sufficient to permit entry of the display between the upstanding sections of the display device. Once the display is so inserted and aligned as desired between the spread apart contiguous sections, the finger pressure on the base portion is removed whereupon each section moves toward the other to fix the display therebetween. 7

It is a feature of the invention that when the assembled members are positioned on a supporting surface in a supporting upright position for the display device, the combined weight of the display and the upstanding sections acting on the-base portions will produce, by virtue of the resistance to displacement offered by the supporting surface, an effective counter force which acts on the base portions to urge the upstanding sections of each member into, tighter than normal, engagement with the display.

Objects and advantages of the invention will be apparent from the following disclosure taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a perspective view of the display device of the invention;

FIG. 2 is a perspective view of the device with the upstanding sections thereof spread apart for insertion of a display;

FIG. 3 is a vertical section through lines 3-3 of FIG.

FIG. 4 is a perspective view of the member which, when assembled in pairs, constitute the display device of the invention;

. ,FIG. 5 is a bottom plan view partly in section to show the manner in which the individual members of the display device are assembled; and

FIG. 6 is a perspective view of a second embodiment of the invention.

In FIG. 4, I have illustrated in perspective view the basic member used for forming the assembly of FIG. 1. As will be seen from FIG. 4, the basic member 1 is constituted of an upstanding section 2 and a base portion 3 offset from the upstanding section and preferably inclined with respect thereto at an obtuse angle, as more clearly shown in FIG. 1.

The upstanding section 2 is formed with longitudinally spaced apart interconnecting means preferably comprising a projection 4 and a slot 5 which respectively cooperate with a like slot and projection of a separate identical member for interconnecting the two members into an assembled construction. The assembled display device is shown in FIG. 1.

More specifically, two identical members 1 may be used each having an upstanding section 2, base portion 3, projection 4 and slot 5. For assembling the two members, one member is merely reversely related to the other so that the projection 4 on one of the members is received in the slot 5 of the other member and the ,slot in the one member receives the projection 4 of the other member. The slot 5 in each member is sized to snugly receive the projection of the other member. Also, the projection 4 and slot 5 should be symmetrically disposed and uniformly spaced with respect to the central vertical axis 6 (see FIG. 1) in such manner that when one of the members is reversely related to the other, the projection 4 on each member will fit into the slot 5 of the other member.

As seen in FIGS. 1, 2 and 3 a complementary acting interlock is provided between the upstanding sections 2, 2 of the pair ofmembers and results from the projections on the separate upstanding sections entering the slots in the adjacent sections from opposite directions.

This interlock has been found to resist ready separation of the members. In fact, a positive separating force is required to separate the members so joined.

it will also be noted that the longitudinal walls defining each slot act as bearing surfaces about which the projections may be pivoted upon application of downwardly or upwardly directed forces upon base portions 3, 3. As seen in FIG. 2, upon application of a downward force on base members 3, 3, the projections are pivoted about the slot bearing surfaces in a direction to cause angular separation of the upstanding sections 2, 2 a sufficient distance to permit insertion of a display 7 between the separated sections. Preferably each member is made of plastic material which although substantially rigid has sufficient resilience so that when downwardly imparted finger pressure on the base portion is terminated the-upstanding sections will automatically return from their positions in FIG. 2 to their positions in FIG. 1.

When an upwardly directed force is applied to base portions 3, 3, the upstanding sections 2, 2, by virtue of the direction of pivotal movement of the projections 4 about their bearing surfaces pursuant to such upward force, will be urged into tighter than normal engagement. Advantageously, such tighter than normal engagement will occur when the display device is supported on a supporting surface. I

The embodiment of FIG. 6 is similar to the embodiment just described excepting that the upstanding sections 2', 2' are curved and the base portions 3', 3 are offset in one direction on one member and in an opposite direction on the other member to provide a support for the display device. The shape of the projections and the slots will be seen to conform to the shape of the upstanding sections.

While the base portions have been shown as extending along the entire longitudinal extent of the upstanding sections, it will be apparent that this is not necessary. Obviously, only such length need be used as to provide a firm support. Also, the base portions, where of minimal length, should be provided in the region between the slot and the projection to permit ready movement of the upstanding sections into their positions shown in FIG. 2.

What is claimed is:
