(Cl. 404-63) This invention relates to display devices and more parnited states Patent@ desirable or expedient for the display of the information ticularly to a panel on which various information may be displayed.

An object of the invention is to provide an easy, systematic and simplified display device using small cards and color combinations to keep information current and easily accessible for various types of organizations, either public or private. Y

The information contained on the cards will, of course, vary in accordance with the organization using the display device. In each instance, though, there is a section having a plurality of removable channels for holding the cards. The channels are preferably parallel and in a vertical arrangement and are very easily separated yfrom the panel to alter the card carrying information thereon. Further, the display device has a plurality of card pockets which are arranged in a storage compartment that is readily accessible at the front of the panel. Heading cards are located above the channel `section and here again, the type of information thereon will be varied in accordance with the particular use of the display dev ice. l

One of the important features of this invention is found in the construction of the channels. Each channel has a pair of sides bent inwardly at an angle toward the center of the channel. The channels are preferably made of metal, although they may be made of plastic or some other substance. When made of metal the sides are of double thickness with the inner panel of each double thickness side terminating at a place very slightly spaced from the plane of the back wall of the channel. This slight spacing is exceedingly important. It is of a width dimension equal to the thickness of the card or cards used in the channel so that small grooves are formed by these spaces. In this way it is possible for at least one-half of a channel full of cards to be slid at one time for inserting additional cards without having to move the cards one at a time. In the absence of this groove of proper dimension with rela- .tionship to the thickness of the cards, the cards would slide over top of each other when one tried to push a whole or part of a column of cards simultaneously.

These together with other objects and advantages which will become'subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Patented July 12, 1960 Figure 5 is a perspective view of one of the trays showing the groove at the sides of the channel.

In the accompanying drawings there is shown va display device 10 which has a at panel 12 which may be hung or otherwise fastened to a wall or other supporting surface or which may `be used in any other way deemed on the -cards carried by the panel.' Two horizontal rows 14 and `16 of Vcards are at the top part of panel 12, these being heading cards, although the information thereon, -like the information on all of the cards used in the display device, may be varied. Cards 14 are disposed in channel 18, while cards 16 are disposed in channel 20. Channel 18 is made of an upper strip 22 and a lower strip 24, the strip 24 beingcornmonto'channels 18 and 20v respectively. These strips have elongate grooves 26 and 28 near the front surface of panel 12 (Figure2) so that the thin exible cards 14 may be exed, placed in channel 18 and then released so that the inherent elasticity of the cards 14 will return them so that-their edges become lodged in the grooves 26 and 28. When in this position, vthe cards are slightly arched, and they are slidable in channel 18 between the ends of the channel at which they contact the shallow sides 30 and 32 along the side edges of panel 12. Channel 20 is constructed in exactly the same way with strip 24 having a groove 36, and strip 38 that is parallel to strips 24 and 22, having a shallow groove 40 to accept the edges of cards 16.

The lower part of the panel 12 has a storage compartment 42 which is provided with a bottom wall 44 and a front wall 46. There are short end walls 48 and 50 secured to the bottom wall 44 and the front wall 46. The storage compartment has a number of dividers 52 separating it into several pockets of correct Size for the various cards used in the display device.

The main information supplying portion of the display device has a plurality of channels 60r retained parallel to each other and in a vertical arrangement. horizontal strip 38 has a front face or wall 62 with an elongate slot 64 behind it land formed `by -an undercut vin wall 62, spacing a part of the strip 38 from the front surface of panel l12. The lower horizontal strip 66 has an upstanding wall or flange 68 which is also slightly `spaced from the front surface of panel 12 thereby forming an upwardly opening groove or pocket 70. The two grooves or pockets 70 and 64 are spaced from each other with the inner extremity surface of each being of a spaced apart distance in excess of the length of each channel `60 so that insertion and removal of the channels is accomplished by vertically sliding the channels in an upward direction to move them deeper into pocket 64 and then moving them either toward the surface of panel 12 (when inserting the channels) or moving them at their lower parts away from the surface of panel 12 (when removing the channels).

A typical channel 60 is'shown in detail in |Figure 5. It has two sides or side walls 74 and 76, each of which is ilattened at its ends, thereby forming attened parts 78 which are fitted ilush against the surface of the bottom wall 80 of channel 60. This forms an upper and lower limit for the sliding movement of cards 82 that are supported by channel 60. Further, sides 74 and 76 are inclined inwardly toward the longitudinal center line of the channel and they are made of two thicknesses of material when the channels are constructed of metal. Each thickness may be considered asa short panel, there then being panels 82 and 84 for side 74 with the `In this way the panel 84 may be constructed slightly shorter than'panel 82 thereby leaving an elongate groove -86 defined by the sans l Upper o space between the longitudinal edge of panel 84 and the adjacent part of the surface of wall 8l?. The depth of groove 86 is made equal to the thickness of card 82 so that cards cannot pile on each other when a plurality of cards are slid in the channel simultaneously. This makes it possible for a number of cards to be moved up or down in the channel simultaneously so that it is easy to insert additional cards without removing all of the cards in one channel simply to insert one or more additional cards in the channel.

Y The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modications and equivalents may` b e resorted to, falling within the scope of the invention as claimed.

What is claimed as new is Vas follows:

1. In a display device, the combination of a panel, a pair of strips provided in spaced relation on said panel, said strips having opposing faces provided at the surface of the panel with undercut grooves, a plurality of elongated channels extending between said strips and having substantially flat end portions removably received in said grooves with said channels resting against the surface of d the panel, said channels including lateral keeper flanges extending between and of a length lesser than the distance between said strips whereby to facilitate insertion and removal of the channels in and from said grooves, and a plurality of exible display cards removably positioned in said channels in engagement with said anges. 2. The device as dened in claim 1 wherein each of said channels also includes a iiat bottom wall, said keeper anges being angul'ated inwardly from side edges of said 10 bottom wall and being doubled under themselves with the freeedges of the doubled under portions being spaced from said bottom wall by a distanee equal. to the thickness of said cards, whereby to prevent sliding of one card over another in said channels.
