Claims
I claim:
1. A poster hanger for supporting and suspending a poster
comprising:
an elongated substantially rigid channel-shaped member having a
uniform cross sectional configuration in the form of an inverted U,
the parallel opposite depending side flanges of the U terminating
in upwardly and inwardly converging retaining flanges which
terminate in laterally spaced poster-gripping edges, said side
flanges being yieldable to permit the lateral gap between said
retaining flange gripping edges to widen as a poster upper edge is
slid upwardly through said gap, said gripping edges being adapted
to maintain a resilient gripping force on a poster sufficient to
hold it suspended from the hanger, said retaining flanges also
functioning to define an upwardly extending retaining lip adapted
to interlock with a downwardly bent flange extending along the
length of a poster top edge to thereby create an interlocking
retention of the poster flange behind said lip which normally
prevents the poster from being removed from the hanger except by
longitudinally withdrawing it the full length of the hanger.
Description
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to hanger structures and more in
particular to hanger structures for substantially flat sheet
materials.
In hanging substantially flat, decorative sheet materials such as
pictures, posters, record covers, leaf calendars, charts or the
like to a supporting surface, conventionally separate means are
employed. One of the means is associated with the particular
material to be hung and the other means generally comprises a
supporting hook associated with the supporting surface, which is
generally semi-permanently embedded in the supporting surface. This
conventional arrangement of hanging flat sheet material from a
likewise generally flat supporting surface, is objectionable in
that first: the hanger means associated with the flat sheet
material are usually permanently fastened thereto and distract from
the general decorative appearance of the sheet material and,
secondly: the supporting means associated with the supporting
surface are generally damaging to the supporting surface by being
embedded therein.
This conventional arrangement is further objectionable, in
consequence of the above defined structure, in that selective
relocation of the hung sheet material from one place to another is
made more difficult, time consuming and as stated before, may be
damaging to the supporting surface by having to relocate the
semi-permanent supporting means from one location on the supporting
surface to another.
Accordingly, the present invention provides an improved hanger
means for flat sheet material which has no potion permanently
fastened to either the supporting surface or to the supported sheet
material. The improved hanger does not distract from the general
decorative appearance of the sheet material but rather adds a
decorative touch to the sheet material to be supported.
Additionally, the hanger has easily applicable and selectively
removable means for securement of the hangers to the supporting
surface without causing damage to the supporting surface.
The present improved hanger structure comprises a longitudinal
channel member generally of U-shaped cross-section which along one
side provides a slot formed by inwardly and toward each other
inclined resilient tab members integrally formed with and extending
from the opposite flanges of the channel member whereby the
respective sheet material may be clamped within the channel member
by insertion between the resilient tab members. If the decorative
sheet material is provided along one or two opposite sides with
integral hook means, which is often the case in such materials as
posters and the like, the hook means may be conveniently hooked
over a selected tab within the channel type hanger member.
One of the longitudinal flange portions of the hanger member is
provided with one or more pressure sensitive adhesive portions by
which the hanger members may be conveniently secured to a
supporting surface and similarly conveniently removed therefrom for
relocation.
Further advantages and distinct features of the present invention
are set forth in the following detailed description of a preferred
embodiment thereof with reference to the attached drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1 and 2 of the attached drawings, a
decorative flat sheet material, such as a frameless picture, record
cover or the like, is indicated by the numeral 10 and has an upper
longitudinal margin 12 by which the sheet material 10 is supported
within the present improved hanger structure 14.
The hanger structure 14 is comprised of a longitudinal, rectangular
channel member having a generally U-shaped cross-section as seen in
FIG. 2 and more in detail in FIG. 5. The hanger 14 comprises
opposite longitudinal side flanges 16 and 18, respectively,
integrally connected to a transverse bridge portion 20 to form a
U-channel configuration.
With more particular reference to FIG. 5, the free ends of the
longitudinal side flanges 16 and 18 of the hanger 14 are each
provided with a longitudinally substantially flexible tab portions
22 and 24, respectively, which may be formed integrally with the
lower ends of the side flanges 16 and 18 by any known manufacturing
process. The longitudinal tab members 22 and 24, respectively, are
bent inwardly into the U-channel between the side flanges 16 and 18
and extend in a converging direction towards each other.
In order to hang the sheet material 10 which, as mentioned, may be
a record cover or the like, the upper margin 12 of the sheet
material is inserted between the tab members 22-24 into the
U-channel of the hanger 14 and is retained therein by means of the
flexibility of the tab members 22-24 which exert an opposite
retaining force against the sides of the margin 12 of the sheet
material, sufficient to retain the sheet material in a free hanging
position in the U-channel type hanger 14.
The hanger 14 may be made from any suitable, preferably
lightweight, material such as sheet metal or from a suitable
synthetic material such as nylon, perlon, Teflon or the like and
may be colored or ornamented for decorative purpose to similate a
frame, adding to the aesthetic appearance of the sheet material
10.
In one form of the embodiment in FIG. 1 and 2, for hanging the
sheet material 10 onto a supporting surface, such as a wall, a wire
hanger 26 is provided of a shape generally resembling a wire cloth
hanger having its longitudinal base portion extending through the
U-channel type hanger 14 to abut underneath the transverse bridge
portion 20 thereof. The opposite, toward each other converging leg
portions of the wire hanger 26 extend into another U-channel hanger
member 14a of substantially shorter dimension. The short hanger
member 14a is disposed in reverse position to the primary sheet
material hanger 14 and is provided along one of its side flanges
with pressure sensitive adhesive portion 28 adapted for attachment
to the supporting surface (not shown). It will be understood, that
the intermediate wire hanger 26 and supporting hanger 14a may be
omitted and the adhesive portion 28 may be provided directly on the
sheet material supporting hanger 14 for direct attachment to a
supporting surface, as will be described in connection with the
embodiment in FIGS. 3 and 4. Additionally, the wire hanger 26 may
be replaced by a decorative cord.
The sheet material 10, supported by the improved hanger 14 of the
present invention, as indicated is of relatively stiff material,
such as cardboard or a plastic as generally used for record covers
or the like, and which is of sufficient rigidity to hang flat
downwardly from the supporting hanger 14 without crinkling or
curling-up.
In the embodiments of FIGS. 3 and 4, a pair of the present improved
U-type hanger member 14 is utilized to support the upper and lower
margins of a sheet material 30, which in this instance, may be of a
relatively soft, foldable material such as used for posters, single
sheet calenders, charts and the like. These sheet materials usually
have a stiffening flange provided along their upper and lower edges
made of sheet metal or the like which, in the embodiments in FIGS.
3,4 and 6 is utilized to retain the flexible sheet material 30 in
the hanger member 14.
As seen in FIG. 6, the upper stiffening flange 32 of the sheet
material 30 is slightly bent outwardly so that, when the upper
margin of the sheet material 30 is inserted in the U-channel type
hanger 14, the stiffening flange 30 will hook over one of the
longitudinal tab members 22 or 24, respectively, as shown, to
thereby retain the sheet material 30 in a supporting downwardly
depending position in the U-channel type hanger 14. In order to
prevent crinkling or curling of the flexible sheet material 30, the
lower margin of the sheet material, which is likewise provided with
a stiffening flange 32, is similarly supported within another
U-channel type hanger member 14 disposed in opposite direction to
the upper hanger member 14, as seen in FIG. 4.
To support the sheet material 30 in a depending position from a
supporting surface, one longitudinal side flange 16 or 18,
respectively, of the hanger member 14 is provided with a plurality
of pressure sensitive adhesive portions 28 to attach the hanger
member to the respective supporting surface (not shown).
Conversely, the sheet material 30 may be hung in the fashion
illustrated in FIGS. 1 and 2.
The provision of the lower hanger member 14 for the flexible sheet
material 30 is provided to add sufficient weight and stability to
the sheet material 30 so that, when the sheet material is hung in
position it is not liable to crinkle or curl-up on itself. However,
if preferred, the lower hanger member 14 may likewise be provided
with pressure sensitive adhesive portions 28, as shown in FIG. 4,
for attachment to the supporting surface to securely maintain the
sheet material 30 in a flat stretched-out position.
Thus, it will be obvious from the foregoing description and the
appended drawings that the present invention provides an improved
hanger structure for flat sheet material to be supported from a
supporting surface which is constructed such as not to damage the
sheet material in hanging and which adds a decorative touch to the
sheet material when applied thereto.
The present improved hanger structure is such as to permit easy
relocation of the sheet material from one supporting surface to
another without damage to the supporting surface and permits
separation of the sheet material from the hanger for interchange
with another sheet material.
The present improved hanger structure is particularly adaptable for
all types of sheet materials, decorative or otherwise, which are
not initially provided with integral hanging means.
Although the present invention has been described by means of a
preferred embodiment, various changes in detail and material of the
structure may be made without departing from the spirit and
essential characteristic of the invention as indicated by the scope
in the appended claims.
