COMBINATION BOOK PROTECTOR AND READING PROP
Abstract
A pair of book-cover-size panels are joined by a flexible web,
so that when book is closed one panel overlies each book cover and
web overlies book spine. Flaps hinged to upper edges of panels are
located against inner surfaces of book cover to connect panels to
covers. Panels may be swung rearwardly to serve as book prop. A
single flexible band, which may be stretchable, is secured at its
ends to the panels, extends around the pages of an opened book, and
extends between the flaps at their lower edges, to limit rearward
swing of panels, hold pages down, and prevent accidental separation
of the device from the book.

combination book protector and reading prop comprising
a pair of stiff panels having a size comparable to that of the book
covers and adapted to be placed against the outer surfaces of the
book covers, respectively,
a flexible connector between said panels adapted to extend across
the spine of the book,
means articulating the upper edges of said panels in hinged
relation to the corresponding upper edges of the book covers, said
articulating means comprising
flaps of stiff material hingedly connected to the upper edges of
said panels and adapted to lie flat against the inner surfaces of
said book covers, respectively,
an opening in each of said flaps,
whereby the panels can overlie and protect the book when it is
closed and can be swung rearwardly away from the book covers to
serve as props when the book is opened, and
a single flexible band having ends secured to said prop panels,
said band extending forwardly from its end and adapted to overlie
the pages of an open book, and said band extending through said
openings in said flaps, and means for preventing said band from
being removed from said openings by movement with respect to said
flaps in a direction away from said articulating means, so that
said band serves simultaneously (a) to limit the rearward swing of
said panels, (b) to hold the book pages down, and (c) to prevent
the book covers from accidentally sliding out from between their
respective panels and flaps.

Description
This invention relates generally to book accessories, and has
particular reference to a combination book protector and reading
prop.
In my U.S. Pat. No. 3,339,875 a combination book protector and
reading prop is disclosed intended for use with a conventional book
having front and rear covers and an intermediate spine. When the
device is associated with such a book, it serves as an effective
book cover and protector when the book is closed, and can be
adjusted to serve as a rear prop for the book when the book is
opened. This protector and prop has served, and continues to serve,
admirably in practice. However, it has been found that for certain
situations a combination book protector and reading prop of simpler
construction adequately serves the purpose.
It is therefore a general object of the invention to provide a
combination book protector and reading prop of simple construction
which is easily applicable to a book, inexpensive from a
manufacturing standpoint, and attractive in appearance.
Several features and advantages of the invention will be apparent
from the following description in which reference is made to the
accompanying drawings, in which:
FIG. 1 is a perspective view of a combination book protector and
reading prop shown in association with a conventional book, the
book being in opened and propped condition;
FIG. 2 is a horizontal cross-sectional view substantially along the
line 2--2 of FIG. 1;
FIG. 3 is a fragmentary vertical cross-sectional view substantially
along the line 3--3 of FIG. 1; and
FIG. 4 is a fragmentary perspective view of a portion of FIG.
1.
The book chosen for illustration in FIGS. 1-3 has front and back
covers 10 and 11, a spine portion 12, and the usual pages 13 bound
to the spine 12. The accessory forming the subject of this
invention is optionally applicable to the book and comprises a pair
of stiff panels 14 and 15, a flexible connector 16 extending
between the panels and adapted to extend across the spine 12 when
the book is closed, and a means for articulating the panels 14, 15
to the covers 10, 11 of the cook, respectively, along the upper
edges. Flexible connector 16 may, as shown, be integral with panels
14 and 15 and joined to the panels along hinge-defining score lines
20, or it may be a separate strip of material having margins
overlapping the panels and secured thereto as by adhesive.
The panels 14, 15 have dimensions comparable to those of the book
covers themselves, and the connector 16 made to have a width
substantially equal to the width of the spine 12 of the book with
which the accessory is to be used. It may be convenient to make the
panels 14, 15 of rectangular elements of stiff material such as
cardboard or the like, and to provide these elements with a
covering of relatively thin paper or its equivalent. In the device
chosen for illustration, such a thin covering is shown at 17 (see
FIGS. 2 and 3) and it is caused to extend across the entire inner
and outer surfaces of the intermediate stiff element 18, the outer
edge of the latter being also enclosed as indicated at 19.
The articulating means comprises relatively stiff flaps 26 and 27
hinged along their upper edges to the upper edges of panels 14 and
15, respectively. The articulation may be attained by extending the
covering layers 17 forwardly over the front and back surfaces of
the flaps 26 and 27. This is most clearly shown in FIG. 3, and
creates a flexible hinge connection at 29. Each flap 26 and 27 may
be made comparable in size to that of the book cover 10 or 11 with
which it is associated, although this is not essential.
The device includes a flexible band 21 whose ends are secured to
the panels 14 and 15. This securement may be effected, as shown in
the drawings, by passing each band end through a hole in its
respective panel and then tying a knot 22 at the end to prevent it
from passing through the hole. Each hole may be lined by a grommet
for strength. The band may have any desired width and may be
composed of any suitable material. However, a cord having elastic
properties is preferred. The band 21 extends from each of its ends
at an angle downwardly and toward flexible connector 16 to a point
of connection with the flap 26 or 27 closest to it. In the present
example, the connections between band 21 and flaps 26 and 27 are
slidable connections defined by a grommet-lined hole 28 near the
lower edge of each panel through which band 21 passes freely.
However, the connections could be fixed if desired. The outer edge
of each flap 26 and 27 may be furnished with a series of notches 30
which serve as positioning means for band 21. These notches are
useful in case it is desired to adjust the position of the band
portion covering a book page.
Each band portion extending between a knotted end 22 and a hole 28
passes over a corner of open book pages 13, as shown in the
drawings, to hold the pages of the book down and thus help to
maintain the book in opened condition. This portion also serves as
a means for limiting the rearward swinging movement of the panels
14 and 15 when they are adjusted into the book proping position.
The band portion extending between holes 28 is positioned beneath
the book pages 13 and thus helps to hold flaps 26 and 27 in place
and prevent the book covers 10 and 11 from accidentially sliding
out from between their respective panels and flaps which would
result in disengagement of the device from the book.
The practical nature of the device, and the ease with which it may
be used, will be readily apparent. Having chosen a book protector
whose flexible connector 16 is comparable to the width of the spine
12 of the book, the user applies the accessory device to the book
by swinging prop panels 14 and 15 way from flaps 26 and 27, opening
both covers 10 and 11 of the book, and slipping all the book pages
(while they are held closed) through the opening defined by the
opposed edges 29 of flaps 26 and 27, the upper edge of connector
16, and the portion of band 21 extending between holes 28. Each
flap will then be arranged between a cover of the book and the book
pages. Band 21 is caused to extend over corners of the open book
pages. When the book is closed, the panels 14 and 15 lie closely
against the outer faces of the book covers, and serve as protective
enclosures. The band 21 may serve as a useful book mark. When the
book is opened, it can be propped into the condition shown in the
drawings by adjusting the book covers into substantial alignment
and then swinging the panels 14 and 15 rearwardly. The extent of
this swinging movement is limited by the end regions of the band
21.
It will thus be seen that a device of thoroughly practicable
character has been devised, readily adaptable for use with any
conventional book to serve as an effective book protector and as a
reading prop.
It is to be understood that some of the details herein described
and illustrated may obviously be altered by those skilled in the
art without necessarily departing from the spirit and scope of the
invention as expressed in the appended claims.
