1 Claim. *1
This invention relates to display equipment and refers more particularly to improvements in display devices of the type employed to illustrate charts or other educational data.
One of the principal objects of this invention is to provide a display device having a loose leaf binder characterized in that it enables suspending charts or other display sheets in juxtaposition to each other on either or both sides of the supporting member for the binder.
Another object of this invention is to provide a display device having spring operated holding rings capable of being readily manipulated to enable charts or other display data to be quickly engaged therewith and having relatively straight portions projecting laterally outwardly from opposite sides of the ring supporting rail to permit suspending the charts or display sheets on either side of the supporting member in juxtaposition to each other.
A further object of this invention is to provide a demountable display device having means on the ring supporting rail enabling the latter to be readily attached to a stand or tripod when it is desired to illustrate the charts or other display sheets.
The foregoing as well as other objects will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:
Figure 1 is a diagrammatic perspective view of a chart display device embodying the features of the present invention;
Figure 2 is a bottom plan view of a portion of the display device shown in Figure 1;
Figures 3, 4 and are respectively cross sectional views taken on the planes indicated by the lines 33, 4-4 and 5-5 of Figure 2'; and
Figure 6 is a view similar to Figure 3 showing a slightly modified form of the invention.
Upon reference to Figure l is will be noted that the reference character l0 indicates a display device having a collapsible tripod I l of conventional construction and having a holder l2 attachable to the tripod. The holder l2 comprises an elongated sheet metal rail of inverted channel shape cross section having a transversely curved base 13 and having flanges l4 flared inwardly in a manner to provide longitudinally extending pockets 15 at opposite sides of the rail.
Carried by the rail is a pair of spring type holding rings l6 and I1 spaced from each other in the direction of length of the rail and disposed in parallel planes extending transversely of the rail. As shown in Figure 3, each ring comprises complementary sections having the adjacent ends at the .top normally abutting each other and having the opposite end portions I8 extending into the channel-shaped rail through openings formed in opposite sides of the channel. The end portions l 8 are substantially straight and project sufficient distances beyond opposite sides of the holder or rail l2 to enable suspending a substantial number of display sheets in juxtaposition to each other on either or both sides of the holder or rail I2.
Referring now to Figure 2 of the drawing, it will be noted that corresponding sections of the rings are connected together by rods l9 having intermediate portions 28 respectively pivot-ally engaged in the pockets [5 at opposite sides of the rail i2. Each rod has aligned knurled or serrated portions 2! adjacent the ring sections at opposite ends thereof and the portions 22 of the rods which connect the intermediate portions 20 to the serrated portions 2| are bent inwardly with respect to the flanges M of the channelshaped rail to position the aligned serrated portions on one rod in mesh with the corresponding aligned serrated portions on the other rod. Thus the ring sections projecting from one side of the rail l2 are not only connected together but are also connected to the ring sections extending from the opposite side of the rail with the result that movement of one ring section efiects a corresponding movement of the other ring sections. In addition it will be noted from Figure 3 of the drawing that the serrated portions 2| of the rods l9 are offset laterally with respect to a horizontal plane including the intermediate portions 20 of the rods so that the rods are tensioned upon initial movement 01 the ring sections to either their closed or open positions. As soon, however, as the serrated portions 2| of the rods are moved sufficiently to cross the horizontal plane in either direction of travel, the energy stored up in the tensioned rods snaps the ring sections open or closed.
As previously stated, the holder or rail I2 is attachable to the upper end of a tripod l I and for this purpose a nut 23 is welded or otherwise secured to the bottom surface of the rail intermediate the ends of the latter. The nut is threaded in the manner shown in Figure 5 to readily detachably receive a correspondingly threaded end on the tripod ll. When the rail i3 is in assembled relation with the tripod, the rings may be readily manipulated to accommodate a plurality of charts or display sheets. These sheets may be suspended on either side of the rail 13 by the portions l8 of the rings, and the number of charts or display sheets capable of being accommodated depends upon the length of the portions I8 projecting from opposite sides of the rail. In the present instance the portions H! are substantially straight so as to enable suspending the charts or display sheets in juxtaposition to each other.
The embodiment of the invention shown in Figure 6 diilers from the construction previously described in that the portions l8 of the rings are curved instead of Straight. With this eXception the construction and operation of the embodiment shown in Figure 6 is identical to the one described above.
What I claim as my invention is:
A display device comprising an elongated rail substantially channel-shaped in cross section and positioned with the channel opening downwardly, a stand having an upright member extending into the channel and secured to the base of the channel intermediate the ends of the rail, a pair of complementary substantially U-shaped sections located in a common plane perpendicular to the rail and cooperating with each other to form a closed ring, the lower leg portions of the U-shaped sections extending laterally outwardly from opposite sides of the rail to enable supporting display sheets in juxtaposition to each other on said leg portions at either side of the rail and permitting the sheets to be transferred from a position at one side of the stand to a position at the opposite side of the latter, and means pivotally supporting the lower leg portions of the U-shaped sections in the channel enabling relative swinging movement of the sections to open and closed positions.
