STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not Applicable.
BACKGROUND OF THE INVENTION
This invention relates primarily to document and note holders, and, in particular to a document or note holder which can be mounted to a surface, such as a desk, cabinet, computer monitor, telephone, etc. to hold a document or note in any desired orientation.
Document holders are commonly used in offices to support papers, memos, notes, and other documents in a manner in which a typist can fairly easily view the document. Often, document holders are mounted to the side of a computer monitor. Such document holders typically include a back surface with a bottom ledge, and the sheet of paper sits on the bottom ledge and rests against the back surface. The paper is held in place, for example, using clips at the top of the back surface or an arm or bar which extends across the page.
Other document holders have been provided which can simply be placed on a desk (or counter) top to hold a note, memo, or other document. One such document holder is shown in U.S. Pat. No. 4,089,116. This document holder is in the form of a ruler having a slot in the top, which receives papers. The slot is closed on its sides, and hence, the holder is limited to receiving papers having a width slightly less than the length of the slot. Alternating blades in the slot form corrugations in the paper to hold the paper upright.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, a document holder is provided which can be mounted to either a vertical or horizontal surface so that the document holder will project vertically upwardly or downwardly or horizontally, as the user chooses to frictionally hold one or more sheets of paper from the top, bottom, or sides. The document holder includes a base and front and back walls extending from the base. The front and back walls each have inner and outer surfaces and are spaced apart to define a slot between the front and back walls. Projections extend from the inner surface of the two walls. Preferably, there are at least three projections: one inner projection extending from the inner surface of one of the walls and two outer projections extending from the inner surface of the other of the walls. The projections are arranged in an alternating pattern. Additionally, the projections are sized and spaced such that, when paper is inserted in the holder, the inner projection will push the paper against the outer projections, and the outer projections will push the paper against the inner projections such that the paper will be frictionally engaged by the edges of the inner and outer projections. Further, the inner surfaces of at least the inner projection or the outer projections are sloped, such that the distance between the sloped projections and the opposing wall varies along the height of the sloped projections. These surfaces define friction-inducing edges, which engage paper, which is inserted in the document holder to frictionally grip the paper. The friction grip is sufficiently strong to prevent the sheet(s) of paper from sliding through, or rotating out of, the document holder under the weight of the paper, even if the holder is completely inverted with the paper projecting downwardly from the slot. To help ensure that the paper remains generally flat or planer when held by the document holder, the document holder includes channels at opposite edges which open into the slot. The channels are co-linear or in the same plane with each other. The channels can be formed, for example, by extensions projecting outwardly from sidewalls of the holder.

DETAILED DESCRIPTION OF THE INVENTION
The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what I presently believe is the best mode of carrying out the invention.
Additionally, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
A document holder
10
of the present invention is provided to frictionally hold a sheet of paper in any orientation. The document holder
10
is substantially smaller than a regular 8½″×11″ sheet of paper. Preferably, the document holder is about 1.5″ wide and about 2″ tall. It includes a base
12
from which a front wall
14
and a back wall
16
extend. The front and back walls include inner and outer surfaces. The outer surfaces of the front and back walls are preferably generally parallel with each other. However, the inner and outer surfaces of the respective walls are not parallel, and the front and back walls both vary slightly in thickness from the top of the walls to the bottom of the walls; the walls being slightly thicker at their bottoms than at their tops. As seen, the base
12
is preferably not perpendicular to the front and back walls
14
and
16
. Rather, the base defines an angle of about 95° to about 100° with the outer surfaces of the front and back walls. The bottom of the base
12
includes a pocket
18
, which receives, for example, an adhesive strip having a removable coating. The coating protects the adhesive strip prior to mounting of the document holder
10
to a surface S. The adhesive strip coating is removed to enable the document holder to be secured to a surface. Although shown to use an adhesive strip to mount the document holder to a surface, the document holder can be mounted to a surface in other ways as well. For example, and without limitation, the document holder can be mounted to a surface using a magnet, glue, suction cups, etc. The surface S to which the document holder is to be secured can be a vertical surface (such as the side of a computer monitor or a cabinet wall) or horizontal surface (such as the underside of a cabinet or a countertop). Thus, the document holder
10
can be used in a vertical orientation to hold paper from the side or in a horizontal orientation to hold paper from the top or bottom of the paper.
The front and back walls
14
and
16
are spaced apart from each other to define a slot
19
into which paper can be inserted. Importantly, the slot is open at its top and along its sides. Preferably, the back wall
16
is taller than the front wall
14
. The taller back wall facilitates the insertion of paper into the slot
19
, as seen in
FIG. 1. A
user can simply place the paper anywhere on the outer surface of the front wall, wipe it toward the protruding back wall until it snaps on to the back wall at which point it can be easily inserted into the slot
19
. This will enable persons to quickly and easily insert papers into the document holder without having to look back and find the slot. This eliminates the need for the user to align the paper with the slot in order to insert the paper into the slot.
The front wall
14
is generally planar, extending the full width of the document holder
10
. As seen, the outer surface of the front wall is also preferably flush with an edge of the base
12
. Hence, the base
12
does not extend beyond the front wall
14
. However, if desired, the front and back walls could be positioned to be generally centered on the base
12
, or to be toward the opposing edge of the base
12
. The front wall
14
includes at least two spaced apart projections
20
extending from the inner surface of the front wall
14
toward the back wall
16
. The back wall
16
also is generally planar and includes at least two side projections or walls
22
and a central projection
24
. The projection
24
has a length at least equal to the distance between the free ends of the projections
20
and the inner surface of the back wall
16
. Hence, at a minimum, the free ends of the projections
20
and
24
are co-linear. The projections
20
and
24
can each have a length such that the projections overlap each other. The projections each have friction-inducing edges that engage the paper, and the natural resilience of the paper against these edges retains one or more sheets of paper in a selected location along the sheet(s). That is, the sheet(s) is (are) retained in the document holder whether the sheet(s) is inserted into the document holder near the top, middle, or bottom of the sheet.
As can be seen best in
FIG. 2
, the side projections
22
form side walls to the holder and there is a gap between the end of the side walls
22
and the inner surface of the front wall
14
through which paper can extend. The walls
22
and projections
24
extend from the inner surface of the back wall
16
towards the front wall
14
. The projections
20
and
24
and the walls
22
are positioned on the front and back walls such that the projections
20
are positioned between the walls
22
and the projection
24
. The front wall projections
20
have upper surfaces
20
a
which are arced and back surfaces
20
b
which are sloped, such that the distance between the projection surface
20
b
and the back wall inner surface is smaller at the bottom of the projection than at the top of the projection. Similarly, the sidewalls
22
of the back wall
16
each have a sloped upper surface
22
a
and a sloped front surface
22
b
. The slope of the front surface
22
b
is significantly steeper than the slope of the top surface
22
a
. The sidewall front surface
22
b
is sloped such that the distance between the wall surface
22
b
and the front wall inner surface is smaller at the bottom of the sidewall than at the top of the sidewall. Hence, as can be appreciated, the projections
20
and walls
22
are wider at their bases than at the their tops. Additionally, the projections
20
and walls
22
have a width over a majority of the height of the projections which is greater than one-half the width of the slot between the inner surfaces of the front and back walls, such that the projections
20
and walls
22
overlap each other. The back wall central projection
24
is substantially smaller in width than the front projections
20
and the side walls
22
and protrudes only slightly into the slot
19
. The forward edge of the projection
24
is generally parallel to the back wall outer surface. The projection is shown to be generally triangular in plan, but could be any other shaper, for example, the projection could be rectangular, triangular, trapezoidal etc. As best seen in
FIGS. 2 and 3
, the projection
24
is centered with respect to both the sidewalls
22
and the projections
20
. However, the projections
20
are closer to the projection
24
than the side walls are to the projections
20
. Stated differently, the distance between the sidewalls
22
and the projections
20
is greater than the distance between the projections
20
and the projection
24
. As noted above, the projections
20
and sidewalls
22
both have sloped surfaces. The distance between these sloped surfaces of the projections
20
and the sidewalls
22
and their opposing surfaces varies, as best seen in
FIGS. 7 and 8
.
The base
12
includes openings
28
between the projections. These openings are provided primarily to enhance the molding process. The inclusion of the holes in the document holder helps reduce mold maintenance and, consequently, increases mold life. The mold includes fingers, which define the slot between the front and back walls of the holder. These mold fingers are received in openings in the mold base so that the mold fingers will be locked into place with respect to the mold base during injection of the plastic resin into the mold. If the mold fingers were not fixed in place and engaged with the mold base, the pressure of the resin during injection of the resin can cause the mold portion which forms the slot between the front and back walls to deflect.
Preferably, the holder includes an extension
26
projecting outwardly from the forward ends of the sidewalls
22
. The extensions
26
each have an inner surface which faces, and is generally parallel to, the inner surface of the front wall
14
. The back wall
16
has a side-to-side width, which is less than the side-to-side width of the front wall
14
. The combined side-to-side width of the back wall
16
and the sidewall extensions
26
is approximately equal to the side-to-side width of the front wall
14
. The extensions
26
and the front wall
14
, in combination, define channels
30
on opposite sides of the slot
19
and which open into the slot
19
. As best seen in
FIG. 2
, the two channels
30
are co-linear with each other or in the same plane with one another. Further, as can be seen, the channels
30
are spaced forewardly from the free ends of the projections
20
.
As can be appreciated, the projections
20
and
24
and the sidewalls
22
will impart a slight bend, curvature, or deflection in paper when paper is inserted into the holder. This curve provides rigidity to the paper so that the paper will stand erect when held from its sides or bottom. When the paper is held from the top or bottom, the side channels
30
help ensure that the opposite sides of the paper will be essentially in the same plane. Thus, the paper extending from the document holder
10
will be essentially flat.
The edges of the projections are friction-inducing edges. The projections
20
and
24
are sized and positioned such that when paper is placed in the slot
19
, the projection
24
will urge the paper against the projections
20
, and the projections
20
will urge the paper against the projection
24
such that the projections
20
and
24
frictionally grip the paper. Additionally, the channels
30
are spaced forewardly from the free ends of the projections
20
. Hence, the paper will have to curve from their point of engagement with the projections
20
to pass through the channels
30
. This induced curvature causes the paper to engage the sidewalls at their inner corners, such that the corners frictionally engage the paper. As can be appreciated, due to the overlap of the projections, the paper inserted in the slot
19
will bend or curve around the projections
20
,
22
, and
24
. The frictional grip of the projections on the paper is sufficient to hold the paper in the document holder, whether the paper is held from the top, bottom, or side. Hence, the paper will not slide through the document holder or rotate out of the document holder. If the paper is held from the side, the paper can easily be moved up and down relative to the document holder to help, for example, a typist to maintain his or her place on the paper. Further, the slight curvature introduced into the paper by the projections will help to prevent the paper from bending should the paper be held by the side and near the bottom of the paper.
The varying width of the slot
19
(from the top end of the slot to the base of the document holder) enables the document holder to frictionally grip and hold different numbers of sheets of paper equally well. Hence, if the document holder is designed to accept, for example, 6 sheets of paper, it will grip one sheet of paper as well as it will grip 6 sheets of paper. As can be appreciated, due to the varying width of the slot, one sheet will slide down into the slot further than six sheets. The distance between the front and back walls, and, the distances between the friction edges of the projections and the inner surface of the opposing wall can be varied for specific use applications, i.e., to accommodate different number of sheets of paper, or different paper stock.
Preferably, the document holder
10
is produced from plastic by injection molding. However, the document holder can be produced in any other desired manner. If injection molded, the projections and walls are all preferably of the same approximate thickness.
As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. For example, more or fewer projections could be used, as desired. The extensions
26
could be eliminated if desired. The width of the slot can be varied to hold different number of sheets of paper or different paper stock (i.e., copy or printer paper vs. note cards). The document holder can be adapted to be mounted to surfaces using, for example, magnetic strips, rather than adhesive. This will allow the document holder to be mounted, for example, on a refrigerator or other ferrous surface. Hook and loop fasteners (such as Velcro) can also be used to removably mount the document holder to a surface. In this case, however, one of the strips of the Velcro would have to be adhered to the surface, for example, with an adhesive strip. The back wall side projections could be made to be wide projections. In this case, the extensions
26
would, in effect, be incorporated into the projections
22
. The projections could be reversed, such that the projections
20
are on the back wall and the projections
22
and
24
are on the front wall. The central back wall projection
24
can be wider if desired, and can have any desired shape. That is, it does not have to be triangular. These examples are merely illustrative.
