PHOTO DISPLAY FRAME AND ATTACHMENT MEANS THEREFOR
Abstract
A display frame for temporarily exhibiting photographic prints
and similar planar display material by magnetic attachment. The
frame includes a planar backing member of metallic material, and
the display material is affixed thereto by means of spots of planar
synthetic resinous material having magnetized metallic particles
therein which are magnetically attracted to the backing member, and
are temporarily affixed to a rear surface of the print or display
material by a coated adhesive substance having relatively limited
adhesive properties relative to hard calendered paper, so as to be
readily peelable therefrom for reuse with other display
material.

Claims
I claim:
1. A combination display frame and attachment means therefor for
temporarily exhibiting relatively hard surfaced light-weight planar
displays comprising: a frame element including a planar backing
plate of magnetically responsive material, at least one attaching
means including a lamina of synethetic resinous material having
magnetic particles imbedded therein, said lamina having a first
surface free of adhesive removably positioned in juxtaposed
relation relative to said backing plate to be magnetically
attracted thereto, and a second oppositely disposed surface, a
double faced adhesive lamina having a planar base, and first and
second adhesive layers positioned on oppositely disposed surfaces
of said base, said first adhesive layer having relatively greater
adhesive strength and being secured to said second surface of said
synthetic resinous lamina, whereby when said second layer of
adhesive is temporarily adhered to a surface of a planar display,
it may be readily peeled from engagement therewith without
disturbing the attachment of said first adhesive to said synthetic
resinous layer.
2. Structure in accordance with claim 1 in which each of said first
and second adhesive layers comprises a rubber based adhesive.
Description
This invention relates generally to the field of display devices
for photographic prints and the like, and more particularly to an
improved display frame and reusable means for affixing the display
material to the frame.
BRIEF DESCRIPTION OF THE PRIOR ART
It is known in the prior art to affix photographic prints and
similar material to a backing board for display using adhesive
tape, mounting corners, clips, pins, tacks and the like. It is also
known to employ a plurality of small bar magnets to hold the
material to be displayed against a magnetically attractive surface,
to permit ready removability. Such bar magnets are, however,
exposed to view, and tend to degrade an otherwise attractive
display.
BRIEF DESCRIPTION OF THE PRESENT INVENTION
Briefly stated, the invention conetemplates the provision of a
display frame defining a display opening, and mounting a backing
board of planar metallic material. The display material is
magnetically affixed to the backing board by providing a series of
mounting means comprising small pieces of a planar synthetic
resinous material having magnetized particles imbedded therein. One
surface of this material is placed in juxtaposed position with
respect to the backing board. The other surface is permanently
adhered to a correspondingly shaped piece of tape or filament
having an adhesive coating on each side thereof, one coating layer
having stronger adhesive properties than the other, and being
permanently adhered to one surface of the synthetic resinous
material. The other adhesive surface having lesser adhesive
properties is selectively adhered to the rear surface of the
photographic print which is normally of hard calendered paper, so
as to be readily removable therefrom, without disturbing the
adhesive attachment of the tape or filament to the synthetic
resinous material. The attaching means may thus be used many times,
until the ability of the adhesive to adhere to the rear of a
photographic print is lost.
BRIEF DESCRIPTION OF THE DRAWING
In the drawing, to which reference will be made in the
specification, similar reference characters have been employed to
designate corresponding parts thoughout the several views.
FIG. 1 is a front elevational view of an embodiment of the
invention.
FIG. 2 is a longitudinal sectional view as seen from the plane 2--2
in FIG. 1.
FIG. 3 is a fragmentary enlarged sectional view as seen from the
plane 3--3 in FIG. 2.
DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENT
In accordance with the invention, the device, generally indicated
by reference character 10, comprises broadly a frame element 11 and
a plurality of individual attaching means 12 for supporting one or
more prints or other display material 13 of well known type.
The frame element 11 may be of any desired construction, as for
example, to include a peripheral wood frame 14 having side members
15 and 16, and end members 17 and 18 defining an opening 19
therebetween. A rear surface 20 defines a continuous rabbet 21
seating a backing member 22 including a metallic plate 23 having an
optional fabric or felt covering 24 upon the exposed surfaces
thereof.
The attaching means 12 are generally similar, and accordingly, a
description of one such means will serve to describe all. Each
means includes a body 26 of flexible planar synthetic resinous
material, such as polyethylene or the like, in which there have
been imbedded particles capable of retaining a magnetic charge.
Materials of this type are known in the art, and are presently
commercially available from Minnesota Mining and Manufacturing
Company (3M) of St. Paul, Minn. This material is cut into circular
or other suitably shaped spots or pieces after one planar surface
of the same has been suitably adhesively coated. Thus, each means
includes an uncoated surface 27 adapted to be placed in
juxtaposition to the backing member 22, and a second surface 28 to
which adhesive is applied, both surfaces being bounded by a
peripheral edge 29.
Since the affinity for most adhesives for hard coated paper
normally found as a rearward surface of a photographic print, and
the surface of the synthetic resinous material, it is necessary
that steps be taken to assure that when an attempt is made to peel
the means 12 from the surface of the print, the adhesive will
remain attached to the means 12. As seen in FIG. 3, this is most
conveniently accomplished by providing a double sided tape or
filament 30 having a first adhesive 31 applied to one surface of a
base 32, and a second adhesive 33 applied to the opposite surface.
The first adhesive is of greater strength per unit area, and is
more or less permanently affixed to the surface 28, while the
second adhesive 33 is employed to interconnect the rear surface of
the print or display material 13. Both of the adhesives 31 and 33
may be well known rubber base types, with the former more thickly
applied, that is to say with a lesser degree of evaporable vehicle,
so that its bonding strength is inherently greater. The tape 30 is
preferably applied to one surface of the body 26 prior to the
cutting of the same from a larger web, to simplify manufacturing
procedures.
In use, it is necessary only to affix one or more of the means 12
to the rear surface of a desired print 13 and place the print upon
the forward surface of the backing member 22 to enable magnetic
attraction between the means and the board to occur. The print may
be left in position as long as desired, and when replacement with
another print is made, it is necessary only to remove the print
with the attached means 12, and peel the same from the rear surface
of the print. Since the adhesive layer 33 has a relatively weak
affinity for the rear surface of the print, it peels relatively
easily, and until detached fibers from the paper stock comprising
the print, or other soil become imbedded in the adhesive surface,
it may be used many times without difficulty. Since the adhesive
layer 31 is considerably stronger, the adhesive will always remain
attached to the body 26 rather than the print, and only reasonable
care need by exercised in the detaching operation.
I wish it to be understood that I do not consider the invention
limited to the precise details of structure shown and set forth in
this specification, for obvious modifications will occur to those
skilled in the art to which the invention pertains.
