FIELD OF THE DISCLOSURE

A portable book holder capable of being adjusted to hold various size
books open.

BACKGROUND

At some point in time we have all read books and wished that we had a
means of holding the book open. Particularly when in college, holding
a book open for studying or reading can become cumbersome when you are
also trying to take notes or complete various papers. Another example
of when it would be nice to have an adjustable book holder is when you
are cooking. Cook books come in all different sizes from small thin
paperbacks to heavy thick hard back books. It is very irritating when
you are cooking to have to keep finding your page because the book
will not stay open. It is also very annoying trying to get a small
book to sit and stay open on most of the book holders that are
currently available.

While there are a number of book holders on the market, they are not
always the best choice. For example, most book holders are not
portable and tend to be made of a hard material that makes them
awkward to carry from place to place. Also, most book holders are
designed to fit a fairly standard size book. Unfortunately, books come
in a wide variety of not only sizes but thicknesses, as well as they
come in hard back and paper back form. All of these variants make
finding a book holder to accommodate all of these needs very difficult.

One example of a book holder that is described in Design Patent No.
Des. 278,578 by Jensen. In this configuration, the book simply sits on
the holder. This book holder also allows the angle of the book to be
adjusted. However, there is no means of holding the book open to a
particular page. Also, the size of the book could potentially be a
relevant factor since there is no way of adjusting for size, but is
purely based on the size of the holder itself.

Another example of a book holder is described in U.S. Pat. No.
4,239,171 by Huls et al. This book holder is made of light materials
and provides some flexible options for using the book holder. For
example, it comprises a center leg that can be used to stick in the
ground or sand (if you are at the beach) or it has additional legs
that can be attached for reading on a solid surface. However, it order
to hold a book, the book must be placed between a piece of plexiglass
and a spring system allowing the book to be held rigidly in place
against the plexiglass for easy reading. Unfortunately, in order to
turn the page, the book would have to be removed from the holder, the
page turned and the book replaced in the holder. With this particular
type of book holder you also have the risk of the spring system
getting stretched and no longer supporting the book.

U.S. Pat. No. 3,951,372 by Quigley is another example of a book
holder. In this particular patent, the holder is comprised of a
foamable plastic material which has been molded. It further comprises
a series of elastomeric strips of inverted V-form. These elastomeric
strips are used to hold the book in place and to keep the book open to
the desired page. The particular book holder is also designed to be
placed on either side for purposes of reading in bed, or it can be
placed on the stomach or thigh or any other portion of the body
depending on whether the reader is sitting, reclining or lying down.

While there are obviously a number of book holder options available
including the standard holder that sits on a cabinet, none of these
book holders address the need for a portable type holder that can
easily be folded up and taken with one to another place. There are
lots to places where people read books and/or study. For example,
depending on your geographical location, you might like to read on the
beach. College students seem to find lots of interesting places to
study from the library to the student union. As books get heavier, the
need for a book holder that accepts these books increases. However,
the weight of the book holder, the ease of use and the portability of
the holder must remain simple and light.

FIG. 1 is perspective view of a portable book holder

FIG. 2 is a detailed view of the length/height adjustment mechanism
depicted in FIG. 1

DETAILED DESCRIPTION OF THE DRAWING FIGURES

In the following detailed description of the preferred embodiments,
reference is made to the accompanying drawings which form a part
hereof, and in which is shown by way of illustration specific
preferred embodiments in which the invention may be practiced. These
embodiments are described in sufficient detail to enable those skilled
in the art to practice the invention, and it is to be understood that
other embodiments may be utilized and that logical, mechanical and
electrical changes may be made without departing from the spirit or
scope of the invention. To avoid detail not necessary to enable those
skilled in the art to practice the invention, the description may omit
certain information known to those skilled in the art. The following
detailed description is, therefore, not to be taken in a limiting
sense, and the scope of the present invention is defined only by the
appended claims.

FIG. 1 is a perspective view of a portable book holder 10 comprising a
base 20, a tilt adjustment 30, an upper section 40, a first upper
piece 50, a second upper piece 60, a hinge mechanism 70, a first
extendable spine support 80, a second extendable spine support 90, a
first book support 100, a second book support 110, a slideable
extension 120, a balance support bracket 130, a height adjustment
mechanism 140, a length adjustment mechanism 150, a semi-circular
shaped base 160, upward extending supports 170 and an adjustment clip
180.

FIG. 1 depicts a portable book holder 10 in an expanded or open
position. The base 20 comprises a tilt mechanism 30 that allows the
upper section 40 to rotate with the base 20 thereby adjusting the
angle of the back of a book when it is placed on the portable book
holder 10. The upper section 40 comprises a first upper piece 50 and a
second upper piece 60 that operate to support the spine of the book.
The first upper piece 50 and the second upper piece 60 are attached by
a hinge mechanism 70 which allows the book to be opened to varying
degrees based on the size of the book and the desire of the reader.
The upper section 40 also includes a first extendable spine support 80
and a second extendable spine support 90 which are capable of being
adjusted to accommodate the height of the book. By having the first
extendable spine support 80 and the second extendable spine support
90, if a reader has a very tall book these supports can be adjusted
upward to provide support and prevent the book from toppling over
backwards. Alternatively, should the reader have a rather short book
and/or limited space then the first extendable spine support 80 and
the second extendable spine support 90 can be adjusted downward into
the first upper section 50 and the second upper section 60,
respectively, to facilitate a shorter book or space restriction.
Additionally, the upper section 40 has attached a balance support
bracket 130, which provides support for the upper section 40. The
balance support bracket 130, is designed to keep the upper section 130
balanced when a larger book is placed on the portable book holder 10.
By providing support on the back of the upper section 40, the portable
book holder 10 is prevented from turning over backwards.

FIG. 1 also illustrates a semi-circular shaped base 160 which has a
first book support 100 and a second book support 110 extending
outward. The semi-circular shaped base 160 allows the user to rotate
the first book support 100 and the second book support 110 to various
widths. By doing this the first book support 100 and the second book
support 110 can conform to different size books. For example, most
children's books are small and not very thick. By being able to adjust
the first book support 100 and the second book support 110, the
portable book holder 10 can facilitate these particular books.
Alternatively, most novels tend to bigger, thicker books. Again, by
adjusting the first book support 100, the second book support 110 and
the first upper piece 50, the second upper piece 60, the first
extendable spine support 80 and the second extendable spine support 90
these types of books can comfortably fit onto the portable book holder
10. The first book support 100 and the second book support 110 each
have an upward extending support 170 located on the end that extends
outward from the semi-circular shaped base. This upward extending
support 170 functions to hold a book on the portable book holder 10,
by preventing the book from sliding off.

FIG. 2 is a detailed view of the height adjustment mechanism 140 which
is identical to the length adjustment mechanism 150. The height
adjustment mechanism 140 is located on the first upper piece 50 and
the second upper piece 60. The length adjustment mechanism 150 is
located on the first book support 100 and the second book support 110.
The height adjustment mechanism 140 allows the user to push the
adjustment clip 180 causing either the first extendable spine support
80 or the second extendable spine support 90 to move up or down.
Alternatively, the length adjustment mechanism 150 allows the user to
push the adjustment clip 180 to adjust the slideable extension 120 of
the first book support 100 or the second book support 110 causing the
slideable extension 120 to extends outward from the first book support
100 and/or the second book support 110. By adjusting the height of the
first upper piece 50 and the second upper piece 60 by extending the
first extendable spine support 80 and the second extendable spine
support 90 and the length of the first book support 100 and the second
book support 110 by way of the slideable extension 120, a user can
easily adjust the portable book holder 10 to fit any size book.

When one is done using the portable book holder 10, it easily folds
down for storage or transportation. For example, if one wanted to take
the portable book holder 10 with them to the library, it folds up and
can be placed is a back pack or other similar carrying device. By
using the height adjustment mechanism 140, the first extendable spine
support 80 and the second extendable spine support 90 can be adjusted
down into the first upper piece 50 and the second upper piece 60,
respectively. The slideable extension 120 of the first book support
100 and the second book support 110 can be adjusted inward. Then the
upper section 40 can be folded downward toward the base 20 by way of
the tilt adjustment 30 of the portable book holder 10. The balance
support bracket 130 will then fold inward toward the upper section 40
and lay against the upper section 40. The portable book holder 10 is
then it its closed position and ready to be transported or stored

Although an embodiment of the present invention has been shown and
described in detail herein, along with certain variants thereof, many
other varied embodiments that incorporate the teachings of the
invention may be easily constructed by those skilled in the art.
Accordingly, the present invention is not intended to be limited to
the specific form set forth herein, but on the contrary, it is
intended to cover such alternatives, modifications, and equivalents,
as can be reasonably included within the spirit and scope of the
invention. For more information go to WWW.GAPATENTS.COM or
