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.

BRIEF DESCRIPTION oF- Tl-lEPRIOR 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 dis- I played 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 boardof 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 calenderedpaper, so as to be readily removable therefrom, without disturbing the adhesive attachment of the tape orfilament 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 or THE DRAWING In the drawing, to whichreference 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 aplurality 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 asa 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 face of the print, it peels relatively easily, and until detached fibers I 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.

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 a rubber based adhesive.

Claims

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.
