Claims
The embodiments of the invention in which an exclusive property or
privilege is claimed are defined as follows:
1. A compact booklike storage and display device comprising: a. a
front cover and a back cover each hingedly connected to opposite
sides of relatively narrower spine, said covers and spine being
generally flat and rigid; b. one of said covers is a compound cover
composed of two generally flat and rigid panels; c. the first of
said panels is hingedly connected to the spine and to the other

perforations in registry with perforations in said other panel; and
6. said annular fastening element extending through said
perforations in said plate; h. said device when closed forming a
generally flat booklike storage unit; and i. said device when
folded into a generally triangular prism, having one of said covers

stack of pages.
Description
This invention relates to a compact presentation folder for the
display of test or other educational material or sales or promotion
material, or the like. When closed, it resembles a book or
notebook. When opened, it assumes the form of an easel on which is
displayed pictorial or typographical stimulus material loosely
bound so that material on consecutive pages can be serially
displayed by flipping the pages from the front to the back sides of
the easel. Although intended primarily for educational use, for
testing and similar purposes, it is useful for various sale and
promotional purposes, for presentation of insurance and investment
data, and the like.
The invention is illustrated in the accompanying drawings in
which:
FIG. 1 is a top plan view of one form of the display device shown
laid out flat and fully open;
FIG. 2 is an end elevation on an enlarged scale showing the same
form of device fully closed;
FIG. 3 is a perspective view showing the device partially open;
FIG. 4 shows the device in an intermediate position preparatory to
forming an easel structure,
FIG. 5 is a perspective view of the device assembled in easel form
for display of the stimulus material;
FIG. 6 is a fragmentary plan view showing in greater detail the
form of a latch or clip member for maintaining the easel stable;
and
FIG. 7 is an end elevation of the structure of FIG. 6 shown partly
in section along the line 7--7 and in the direction of the
arrows.
Referring now to the drawings, and particularly to FIGS. 1 through
5, the display device according to one form of the present
invention comprises a booklike unit, indicated generally at 10. The
unit includes generally a flat rectangular rigid panel 11
corresponding to the front cover of a book, a similar panel 12 of
the same height but lesser width corresponding to the spine of a
book, and a panel 13 generally similar to panel 11 corresponding to
the back cover of a book. Panels 11 and 13 are hingedly connected
to the narrower spine panel 12 as is common in books and
notebooks.
A further auxiliary back cover panel 14 corresponding generally to
panels 11 and 13 is hingedly secured to the edge of panel 13
opposite from spine 12. Panel 14 is foldable so that it may be
folded into face-to-face contact with the inside surface of panel
13, as seen in FIGS. 2 and 3, panels 13 and 14 then together
forming a compound back cover. A stack of a plurality of pages 15
of material to be displayed is loosely bound to the free edge of
panel 14 opposite from its hinged connection with panel 13, as by
means of wire binding or ring binding 16, or the like. The pages 15
are desirably slightly smaller in their overall dimensions than
panel 14 so as to permit the edges of the panels to provide a
slightly overhanging and protective lip for the pages when the
device is in folded book form, as in FIG. 2.
The adjacent edges of panel 14 and pages 15 are provided with a
plurality of perforations 17 to accommodate the loose wire or ring
binding. A latch or clip member 18 is secured to the inside surface
of panel 14, as by being secured by the binding 16, for the purpose
of holding the device in assembled easel form, as explained in
greater detail hereinafter.
The sheets 15 may be imprinted on one or both sides. For test
purposes, the one side visible to the examinee will bear certain
stimulus material and the opposite side of the next adjacent sheet
which is simultaneously visible to the examiner bears related
identifying or explanatory material. Where several sets of stimulus
material may be included in a single device, suitable indexing
means 19 may be provided.
If desired, the inside surfaces of front and rear covers 11 and 13
may be provided with pockets, such as a pocket 20 for receiving a
pencil 21, a pocket 22 for receiving an instruction manual 23, a
pocket 24 for receiving a stack of scoring sheets 25, and the like.
The spine panel 12 is of sufficient width to accommodate the
combined thickness of the plurality of sheets 15, panel 14 and the
material contained within the pockets 22 and 24 so that the closed
unit lies generally flat, as seen in FIG. 2.
The device is assembled to form an easel generally as follows:
The closed unit, as in FIG. 2, is placed on a desk or table with
panel 13 in engagement with the surface. The front cover panel 11
is lifted, as in FIGS. 3 and 4, sufficient to permit panel 14 with
its attached stack of pages 15 to be lifted free, as in FIG. 4.
Then the front cover 11 is folded inwardly toward panel 14 and the
edge lip of panel 11 is caused to engage latch or clip 18 on the
inside surface of panel 14. This is best seen in FIG. 6 and 7.
The latch 18 comprises a thin flat plate 26 having at least two
perforations 27 through which the loose binding 16 (in this
instance shown as spiral wire binding) may pass. The plate has a
plurality of projecting spaced-apart tabs 28 and 29 which together
define a channel into which the lip of front cover panel 11 is
received. This insures stability of the easel structure such that
accidental pressure against the top surface of panel 11 will not
cause the easel to collapse. Although it provides a less stable
assembled easel structure, the latch means may alternatively. be a
simple tab extending along the edge of panel 14 adjacent the
binding 16 generally in engagement with the surface of panel 14 and
extending toward its connection with panel 13. The edge of panel 11
can engage this tab by slipping under it. The latch means is not
essential to the easel structure, but may be eliminated altogether
at the cost of a slight loss in stability.
In assembled position, as shown in FIG. 5, the unit is now ready
for use. The easel is positioned with the surface of pages 15
facing the person or the group to which the material is to be
displayed. Then, one by one, after the material on the front face
of each page 15 has been displayed for the requisite time, that
page is flipped over on the relatively loose binding 16 so as to
lie against the angularly disposed front cover panel 11. The pages
are turned in sequence until all of the desired display material
has been exhibited.
The unit is closed by flipping the plurality of pages 15 back
against panel 14, lifting panel 14 to release the latch 18, lifting
front cover panel 11 slightly to permit panel 14 to resume its
face-to-face engagement with back cover panel 13 and then closing
front cover panel 11. When used for testing purposes, the easel
shields from the examinee the scoring sheet on which the examiner
records responses. In this manner, distraction of the examinee by
the recording of responses is effectively eliminated.
When in assembled form for use as a display easel, the device
resembles a triangular prism whose ends are generally isosceles
triangles. One cover is the base of the prism. The loose wire or
ring binding is at one edge, most generally at the apex. The two
angularly disposed sides are formed by the other cover and the
stack of pages to be displayed.
It is apparent that many modifications and variations of this
invention as hereinbefore set forth may be made without departing
from the spirit and scope thereof.
