Slide display

A foldable slide display of folded paperboard material which includes a folded back panel and a viewing box hingedly connected to the back panel for folding movement between an upright condition and a folded collapsed condition and wherein the viewing box includes a pattern of viewing openings in aligned relation and in registry with window openings suitable for displaying film so that when the device is folded into an open condition, the film may be observed through the viewing openings of the box and the box may include a slide with a magnifying glass for sliding movement therealong for enlarging the image seen on the film.

FIELD OF THE INVENTION 
This invention relates to a slide display and, more particularly, to a 
slide display which is useful, for example, in advertising. 
BACKGROUND OF THE INVENTION 
In the past there have been numerous types of display devices for 
advertising materials. One of the most desirable forms of advertising are 
slides or pieces of film which may be viewed against a light background. 
This invention is of a device which includes a viewing box and means for 
mounting film clips so that the clips can be viewed when the device is in 
an open condition and which includes a viewing box which is adapted to be 
collapsed into a folded condition for mailing. 
It is, generally, an object of this invention to provide an improved slide 
display which is suitable for advertising in accordance with the 
description which is set forth more fully hereinafter.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the drawings wherein like reference characters designate like 
or corresponding parts throughout the several views and referring 
particularly to FIG. 3, it is seen that there is provided a back panel of 
cardboard or foldable paperboard generally designated by the numeral 12 
which includes a fold line 14 thereacross in the central zone. The fold 
line defines, on opposite sides thereof, a first portion 16 and a second 
portion 18. There is a strip zone in the first portion which extends 
parallel to the fold line 14 completely across the first portion 16 and in 
which there are a plurality of aligned spaced windows, 22, 23, 24, 25, 26 
and 27. A retainer means 28 in the form of an elongate strip with adhesive 
longitudinally extending edges is provided to hold a film 29 in each of 
the windows. The film 29 may comprise a strip of different scenes, such as 
are utilized in advertising and may display a product. The retaining means 
28 is preferably of translucent material. 
A viewing box 30 is provided which includes a first and a second side wall 
32 and 34 in upstanding relation with respect to the first portion 16 and 
on opposite sides of the strip zone thereacross. Each of the side walls 
has an upper edge and a lower edge. The upper edges are spanned by a roof 
44 having a first end 46 and a second end 48. The roof is provided with a 
plurality of viewing openings 50, 52, 54, 56 and 60, each of which are in 
registry with one of the windows of the strip zone in the first portion 
16. Means are provided to connect the lower edges of the side walls of the 
back panel along the strip edges, in a hinge-type connection as will be 
explained more fully hereinafter. A slide 61 which includes a magnifying 
means in the form of a glass 62 is slidably mounted on the box which 
includes a guide track 63 connecting into channels which are inturned and 
provided on the lower portion of the slide, see FIG. 4. Stop means in the 
form of downturned ends of the upper sheet or means 63 may be provided to 
limit travel of the slide to movement between the first and second ends of 
the roof. With reference to FIG. 4, means are provided for hingedly 
collapsing and moving the box into an upright position for viewing. To 
this end, a pull member 70 which comprises a panel zone having a first end 
72 and a second end 74 is provided with the pull member being connected to 
the first side wall 34 of the box, that is the side wall which is adjacent 
the fold line 14 and with the second end being connected to the second 
portion of the back panel and, indeed, it may be integral with it or it 
may be taped as at 74 to it. Hinge means 80 are provided in the form of an 
adhesive strip at the connection of the pull member in the first side 
wall. Hinge means are also provided as at 82 in the form of the lower 
terminal edge of the side wall of the box there indicated being outturned 
and adhesively secured to the first portion 16 of the panel 12. The length 
of the pull member and the distance between the first side wall 34 of the 
box at the connection of the pull member and the first side wall and the 
second portion of the back panel being of a ratio such that the angle 
opposite the length of the pull member is about 90 degrees when in the 
position shown in FIG. 4; that is, the box is erected for viewing. When 
the back panel is folded as indicated in FIG. 5, the viewing box will 
collapse to the position shown in FIG. 2 with the various portions of the 
slide display being generally in what may be described as roughly parallel 
planes, see FIG. 2. 
In operation, an advertiser or anyone having items to be displayed in a 
card may insert the film strip and conveniently ship it, with a message 
being written on the card so that the receiver has advertising or a 
message and an opportunity to view what is referred to in the written text 
by simply moving the slide from viewing opening to viewing opening to see 
what is depicted on the film.
